Discrimination and Carpet Cleaning Clients

She had just moved into our area, buying in a very nice neighborhood. When she called about having her carpet cleaned ASAP, she immediately rubbed me the wrong way. You know the type. Combative with you immediately. Demanding (bordering on rude), even before you begin to “tell and sell” your company.
We do an in-home carpet evaluation with potential clients before quoting any pricing for carpet and upholstery cleaning. It allows us to tell the client what they can expect from the cleaning and what the cost will be if they hire us.
We charge by the square foot, so after measuring the areas she wanted cleaned, I gave her our exact down-to-the-penny price. I reviewed the square footages to be cleaned, what was included in the package we offered and finally, the cost to have us clean the carpeting.
It took less than three seconds for her to declare, “That’s too much.” She told me the last company she used had cleaned more carpet and did it for half the price I had just quoted.
I knew from her tone and demeanor that it was over. This woman had no intention of hiring our company. I thanked her for her time and left. Walking back to my van, I silently thanked the cleaning gods that we didn’t have to do business with this woman.
However, five minutes after returning to the office, she called back and informed me she wanted us to clean the carpeting. The time for subtleties was over. “I thought you said our price was too high,” I said. She replied, “Well, if you do a good job, we’ll have you do it. Is tomorrow still available?” Stunned, I told her it was and that we would be there at 9 a.m.
After hanging up, I sat there staring at the phone and thought about this turn of events.
This lady was difficult from the get go. More importantly, she was clearly unhappy even before we set foot in the door to clean her carpet. Why? Because she felt she was being overcharged. No matter what we did, no matter how spectacular the results, I was convinced she would find fault with our cleaning because she was already dissatisfied.
Did I really want to work for her?
I decided to fire her as a potential client. I called her back and told we wouldn’t be cleaning for her.
She was incredulous. “You mean even though I agreed to pay your price, you still won’t clean my carpet?” Yep, you got it. I replied, “it’s just not a good fit. There are plenty of dirt cheap companies who would love to clean for you.” I actually gave her the names of two of our competitors to call.
“Even though I agreed to pay your price?” Those few words spoke volumes to me. She was convinced that I was holding her carpet for ransom. And if she was going to get it back clean, she was forced to pay our ransom price.
BIG LESSON: You can refuse to work for anyone that you choose. It’s important to your business that you embrace this concept.
But isn’t this discrimination? You bet. Is it ethical? Absolutely. Most people equate discrimination with prejudice, which has bigotry and intolerance at its base.
That is NOT what I’m referring to. The definition of discrimination, as it applies to this discussion is “the act, practice, or an instance of discriminating categorically rather than individually.”
Refusing to work for someone is not a personal slight toward that person. It’s simply a business decision.
REALLY BIG LESSON: Never forget that it’s your company. Do you really want to work for just anyone who waves money in front of you? Working for a troublesome client will only steal your joy. It will cause you aggravation that you really don’t need. Life is too short and the problems of business ownership are already complex. You do not need people like the one I just described as clients.
Now extend this concept even further
Many use direct response marketing to obtain new clients. Discrimination is applicable here as well.
You do not want mail to everyone simply because they have a heartbeat. Find out the average home value in your area. Add 10% to the value and that’s who you want to market to. We categorically refuse to clean mobile homes and apartments. We laser focus on homeowners with nicer homes and more disposable income.
To help you sift and sort potential clients, have a substantial minimum service fee. It should be at least $100, preferably $125 or more and this would be after any discounts given.
Remember that line from the last Indiana Jones movie? Before selecting from dozens of cups to drink from, the old knight tells them to “choose wisely.” The wrong decision would be disastrous. As business owners, the same holds true for us. Choose wisely which clients fill your cleaning schedule. The wrong choices won’t necessarily be disastrous… but it will sure feel that way.

How to Train and Groom Precious Human Resources?

“The illiterate of the 21 century will not be those who cannot read and write but those who cannot learn, unlearn and relearn”, Alvin Toffler.

INTRODUCTION:

“By spending just 10 per cent of GDP (RS 4,90,000 Crores) on skill repair, the country would be able to generate extra income of 61 percent of GDP (RS 17,51,487 Crores) for the current unemployable youth”, according to India Labor Report 2007. It indicates the importance of ‘training and grooming’ which is required so as to enhance the efficiency of not only the unemployable youth but also the employed people. In this context, it is desirable to explain briefly about the fundamentals of education, training and development.

EDUCATION, TRAINING & DEVELOPMENT:

Education is a broader concept and it provides all round knowledge, skills, attitudes etc., Training is the narrow area, functional area and is more or less related to job. Training is subset of teaching and education. According to Flippo, “Training is the act of increasing the knowledge and skills of an employee for doing a particular job”1. An automobile engineer having formal education, at times, may not be as capable of an automobile mechanic without formal education because of the training the latter had. The mechanic after working very hard continuously and mechanically for a long period becomes an expert not by education but by training and experience. It is like saying that, in a clinic, a compounder is better than a doctor who acquired a professional qualification. On the other hand, development is career oriented which helps in the growth of the individual as well as the institution.

Training is usually cut out for short term and it is meant for non managers mainly covering technical knowledge. Training is provided for imparting specific skills among operative workers and employees. The corporate trainer or supervisor has a pivotal role to play in this regard. On the other hand, development is cut out for long term and it is meant for managers covering theoretical as well as conceptual knowledge. Development denotes the overall growth of the executives where the executive motivates himself to develop. Rather development is a broader concept when compared with training.

UNEMPLOYABILITY AND UNEMPLOYMENT:

Mr.Amit Bhatia, founder CEO of Aspire said, “Only 39.5 per cent of graduates in India are employable and the challenge is to bridge the HR gap by providing skills training to the other 60 per cent”2.

Presently we have unemployability problem not unemployment problem. Everyone knows what unemployment is but a few are aware of unemployability. In the past, especially before the liberalization, privatization and globalization India had unemployment problem where the candidates had the eligibility, suitability and capability but jobs were not available due to lack of so many opportunities. But ever since the mid nineties many global MNCs have come to India and set up their shops and industries and as a result so many employment opportunities have been created. But unfortunately candidates do not possess the requisite skills and abilities which are expected by the employers. It is a state of unemployability problem. To some extent, it is the result of outdated academic system. The present educational system is theoretical oriented and no way related to the practical application and, as a result, the candidates struggle to get placed. In this context, it is desirable to dwell at length about the relevance of Soft Skills.

SOFT SKILLS:

There is an adage in business, “People rise because of their hard skills and fall because of (the lack of) soft skills”. Hard skills are the domain skills and are also called technical skills. Soft skills are like non domain skills and anything other than the subjective knowledge that helps in effective communication, presentation, team building and leadership are known as soft skills. These are also known as emotional intelligence and the interpersonal skills. To put it in a nut shell, the soft skills and hard skills are two sides of the same coin and the one without the other has no meaning.

IMPORTANCE OF SOFT SKILLS:

Soft skills believe in nurture rather than nature. It manages by interacting between subtle and fickle human beings. It enhances the efficiency at the work place and minimizes the attrition rate. It always makes an individual stay ahead of time.

Soft skills enhance employability of the candidates and provide a solid ground to get adjusted and get along in the organizations more effectively and efficiently. These enhance the core competence and confidence of an individual. The growing widening gap between the talent supply and technical demand can be narrowed down. In a nut shell, proper training in soft skills creates more opportunities for the fresh candidates thereby minimizing the talent crunch in the job market.

There should be inclusion of soft skill subject in the academic curriculum so that students will have confidence and courage to communicate in the corporate world.

Infosys conducted 5 day work shop on Soft Skills titled Special Training Program (STP) for the teaching faculty in Hyderabad in 2007 and it is a step in the right direction and it shows the significance attached to the area of soft skills.

IMPORTANCE OF TRAINING AND DEVELOPMENT:

“William James of Harvard University estimated that employees could retain their jobs by working at a mere 20-30 per cent of their potential. His research led him to believe that if these same employees were properly motivated, they could work 80-90 per cent of their capabilities”.3

Training cuts down the costs and contributes to better utilization of machines and materials. It also helps to reduce the cost of raw materials and products thereby minimizing losses due to waste and poor quality products. Apart from this, it minimizes absenteeism, accidents, employee’s dissatisfactions and grievances. Production and the productivity can be enhanced as wastage is brought down and the employee’s efficiency is increased. There will be qualitative improvement both at the work front as well as at the human resources front. Motivation and morale will be extraordinarily high. Employees do not get boredom with the routine and outdated tools and techniques as training will help them get updated which leads to accepting new roles and responsibilities thereby giving better job satisfaction and sense of achievement. There will be total personal and professional safety thereby preventing health hazards. In a nut shell, there will be all round personal and professional prosperity and growth.

TYPES OF TRAINING:

Below are the various types of training. They are:

1. Induction training.

2. Job training.

3. Apprenticeship training.

4. Refresher training.

5. Internship training.

6. Training for promotion.

Induction Training: It is also known as orientation training as the newly recruited employee is oriented with the rules and regulations and roles and responsibilities of the institution. The employee learns the basic tools and techniques that are required to work on a daily basis. It is basically for short term period to the freshers by supervisors so that the freshers get acquainted with the organization. It is like tuning, training and grooming to the organization with in the shortest possible span of time.

Job Training: It is basically for providing specific skills related to job so that the freshers can perform at ease. It is basically for knowledge and skills’ imparting so as to provide confidence to the newly inducted employees.

Apprenticeship Training: It is like learning and earning where the fresh students will be provided with training related to knowledge and skills of a particular trade. Govt. of India has made it mandatory for a few employers to provide such kind of apprenticeship to students where class room instructions along with on the job training are imparted. Under this the employers get cheap man power and the trainees also get some wages for the work they rendered.

Refresher Training: It is also known as retraining where the employees who worked many years are provided with fresh training to get them updated with the latest developments in technology and other related areas of knowledge and skills. It is in this context, Dale Yoder aptly quoted, “Retraining programmes are designed to avoid personnel obsolescence”. It enhances both efficiency and efficacy.

Internship Training: Under this the educational institution ties up with the industry to provide training to its students for some time so that they get exposed to the industry who can be absorbed if the industry finds them suitable and competent. It is usually for the period from 6 months to 2 years. For instance, the engineering students work in the final year for some time in the business enterprise. So is the case of management graduates where they learn about the business by way of case studies during their class rooms and go for internship during the course or at the end of the course with business enterprises to get practical exposure and expertise.

Training for Promotion: It is a motivational move by the companies where the talented employees are short listed for further and higher training so that they can shoulder the roles and responsibilities when promoted.

TRAINING METHODOLOGIES:

A survey conducted by Kalra 4 indicated that participants would like to have training programs in the following areas:

- Training in taking responsibility/decision-making

- Greater practical focus rather than conceptual focus in training program. It indicates that the employees would like to work in challenging environment to touch their upper limits.

The main objectives of individual training methods could be: demonstration value, developing interest and finally, appeal to senses5. “Experience indicates that almost 75 per cent of what we imbibe is through the sense of right and the rest is through the sense of hearing, touch, smell and taste. From the trainer’s point of view it would be beneficial to utilize as many of the trainee’s senses as possible, in order to improve retention of learning”.

Knowledge, Skills and Attitudes (KSAs) are the basic things that are imparted by way of training. And the same is provided by three training methods such as Cognitive methods, Behavioral methods and Management Development methods. In Cognitive methods, theoretical training that includes knowledge and attitudes is provided. In Behavioral methods, practical training that highlights basically about the development of skills is provided. In Management Development methods, the employees are provided with the training keeping the future requirement in view.

COGNITIVE METHODS:

“Learning is not a spectator sport – - – - it is an active, not a passive, enterprise. Accordingly, a learning environment must invite, even demand, the active engagement of the student”, D.Blocher.

Under the cognitive methods we have the below methods of training:

Lectures: The knowledge is imparted by way of lecturing. The concepts related to specific skills are explained with theoretical classes with case studies.

Demonstration: The concepts so explained by way of theoretical methods will be demonstrated while all the trainees observe the same and learn. It enables the trainees to understand better as the skills are demonstrated in the presence of all. It is having better penetration and retention in the minds of the trainees.

Discussions: Here the work related tasks, skills and concepts are discussed to have better grasping and understanding. Discussions will help us learn effectively as we humans tend to forget 50 per cent of what we learn with in the first 48 hours unless we recall the things first.

Programmed Instruction: It is also known as Programmed Learning which is a self-teaching method particularly useful for transmitting information or skills that need to be learnt and placed in logical order. The instructor is replaced by an “instruction booklet” or a “teaching machine” or both. Again there are two approaches under this one is linear programming and the second one is intrinsic or branching programming and of these two the popularly used one is linear programming.

Under cognitive methods there are also other methods like Intelligent Tutorial System, Computer Based Training and Virtual Reality by which the training is imparted.

BEHAVIOURIAL METHODS:

Under these methods we have the following types of training methods:

Management Games: It is like creating a real life situation under controlled conditions where different teams are created and are encouraged to compete with one another. In this scenario the employees analyze the situation and take decision based on intuition and gut feeling. It is like a trial and error method without any major fall-out. And the feedback is given instantly so that the mistakes are corrected and the right methodologies are learnt and adopted.

Simulation Methods: A simulation method is used to develop, in a controlled environment, a situation that is as near to real life as possible, whereby people can learn from their mistakes. When individuals want to learn car driving they can undergo simulation method. After getting confident then they can go for driving the real cars. Similarly in defence organizations the pilots undergo flying under simulated conditions so as to avert any accident to the aircraft as well as to prevent the loss of life of the pilot. The astronauts and cosmonauts also work number of hours in a simulator before they embark on the real space shuttle aircraft.

Case Study: Harvard law professor, Christopher C.Langdell is the father of case study method. It provides learning by doing.

Yin has defined case study as “an empirical inquiry that investigates a contemporary phenomenon with in its real life context, when the boundaries between phenomenon and context are not clearly evident, and in which multiple sources of evidence are used”6.

Case study is a simulation of a management situation that helps the management graduates to react in a real situation and helps them by providing right direction towards right decision making and problem solving.

In-Basket Method: As the name indicates the problems that need to be addressed are placed in the basket. The trainees are asked to don the hat of the manager and look at the problems with in a given time frame. In day to day life the managers have to work under lot of pressure and under time constraints and deliver the results. The trainees step into the shoes of the manager and provide number of viable solutions towards decision making. And subsequently the same is evaluated by the experts and the comments are offered for improvement.

Role Playing: This technique is widely in developing human relations and leadership qualities. For instance, after delivering the lecture the faculty member may encourage a few of the students to come to the podium to deliver what they understood from the lecture. When student come to the podium and delivers then we can say that he is role playing like a faculty member. The faculty can offer feedback of the delivered lecture by the student. It is only for a limited time that the student feels like that of a faculty member and over a period of time he learns to deliver effectively and efficiently like faculty member by overcoming stage frit.

Under Behavioral Methods there are also other methods of training like Behavior Modeling, Business Games and Equipment Stimulators through which training is imparted.

MANAGEMENT DEVELOPMENT METHODS:

“Management or executive development includes all those activities and programs which have substantial influence on changing the capacity of the individual to perform his present assignment better and in so doing are likely to increase his potential for future management assignment”7.

There are two ways the Management Development is affected – one is by On-The-Job training method and the second is by Off-The Job training method.

On-The-Job Training: It is learning by doing. In this method, the employee is given training at the work place by his immediate supervisor. Under this we have the following methods of training.

Mentoring: Mentoring is the process of helping the mentee to realize the hidden potential or discover the hidden talents. It is a link between the mentor and mentee with the former getting sense of satisfaction and achievement and the latter learning and growing personally, professionally and socially.

“Mentoring is a brain to pick, an ear to listen, and a push in the right direction”, John Crosby quoted. In brief, mentoring can be defined as the relation between an experienced individual and an inexperienced individual where the former provides the training and helps in grooming the latter.

Coaching: In this method the coach provides continuous training to the learner right from the beginning to the end. He constantly and continuously trains and grooms the learner. The coach guides and coaches but does not teach. He provides periodic feedback and evaluation by which the learner can learn quickly.

Job Rotation: An employee is put in various departments of the same organization so that he learns something of everything about all the departments in the organization. He becomes a Jack of all trades and, of course, he is already a Master of a specific trade. It will help an employee to reach higher position as he knows the ins and outs of the organization. And in future, he can not be misled by his subordinates due to lack of exposure to specific department. The prospects are brighter for the employee to become not only an efficient manager but also an effective leader.

Understudy: It is like preparing the subordinate employee to fill the bill as and when the vacancy arises due to resignation, promotion, transfer or retirement of his immediate superior. The advantage of this training is to ensure that the there is no losing the link in the organizational structure. There will be ready made supply of the talent as the subordinate is already is trained and groomed to fill the vacuum or to replace the incumbent.

Under On-The-Job Training Method we have also other training methods like Committee Assignment, Job Instruction Technique and Multiple Management by which also training can be imparted to the employees.

Off-The-Job Training: This kind of training can be acquired by the employee who is away from the work place as he works without any tension and without supervisor. It is only learning not ‘learning by doing’. Under this, we have the below methods.

T-Group Training: It is also known as Sensitivity training and also known as laboratory training as it is conducted under controlled conditions. This kind of training is very sensitive as the trainee is openly criticized or praised for his actions. The feedback is open and should be taken constructively and positively. The trainees who are very sensitive can not digest the feedback if given negatively. That is the reason it is known as Sensitivity training. This kind of training is led by a professional trainer who happens to be a psychologist or the one who knows the psyche of the trainees.

Special Courses: The employer may send the worthy employees for special courses which may benefit both the institution and the individual. The employer may sponsor in special cases with contractual agreement with the employee that the latter will not leave the organization after acquiring the courses and qualifications.

Specific Readings: The articles related to the nature of work are sent to the employees so that they can get updated with the various dimensions of their area and also about the latest developments and happenings. It will help them to apply in their real life scenario and grow both personally and professionally. Most of the employees who have the hunger for knowledge are always on the look out for the write-ups or articles or newspaper cuttings of business magazines like Business Today, Business World, business journals like Harvard Business Review, ICFAI Magazines and business newspapers like The Economic Times, Business Standard, Financial Express etc.,

Conference Training: Companies conduct conferences periodically to exchange information, enhance knowledge base and also to solve problems. In this, the conference members and conference leader will have wider opportunity to grow professionally as different shades of opinions are expressed openly which provides an opportunity to rate one’s opinions vis-à-vis others. It enlightens the individuals participated where do they stand in decision making and problem solving. Besides learning they also develop empathy and respect towards the opinions of other conference members.

Transactional Analysis (TA): It was developed by Eric Berne, a psychiatrist who is best known for his book, Games People Play, which was popularized by Thomas Harris in I’m, OK – You’re OK. Muriel James and Dorothy Jongeward’s book, Born to Win, showed how people could apply TA to their personal lives8. Transaction is the exchange of words and behavior between two people which is concerned with social interaction. Stroke is nothing but feedback or recognition which can be either positive or negative. When you praise some one then it is a positive stroke and when you criticize some one then it is a negative stroke. According to Eric Berne, every person has three ego states such as Parent ego state, Adult ego state and Child ego state. Every person undergoes all the three ego states depending upon the situation and occasion.

Under the Off-The-Job Training, there are other methods like Straight Lectures, Case Study, Simulation Exercises and Role Playing by which also the training is imparted.

HOW TO DESIGN A TRAINING PROGRAM?

Training is subset of teaching and it should be on a continuous basis and Human Resources Manager plays a crucial role to see that the training activities take place on a regular basis.

Before rolling out the strategy for a training program it is necessary to look at the vision and mission of the organization as it helps in designing the training schedule and module properly. It is also desirable to look at the short term goals and long term objectives of the organization. After going through the same it provides a clear cut direction and guideline for the plan of action for training.

Any training program should have the following four stages and steps.

1. Identification of Training Needs,

2. Setting Training Objectives,

3. Organization of Training, and

4. Evaluation of Training.

1. Identification of Training Needs:

It is necessary to find out the critical gaps between the expectations and the realities of the employer. Unless these are found out it is very difficult to design the training program. The technology is changing rapidly and the human resources should keep pace with the rapid changing technology and if the same if not kept then the necessary tools and techniques related to training should be created to keep the employees on the right track and fast track. While identifying the needs it is vital to look at the issue from three dimensions like organizational front, human resources front and at the task front. Efforts should be made to bring effective synchronization and coordination among these three fronts as these are interrelated.

2. Setting Training Objectives:

After identifying the training needs then set the goals and objectives which are in tune with the needs and demands. Once the objectives are set then the next stage is to create training schedule and module. In this context, let us look at the role of trainers.

Role of Trainers: These days there is steady growth of corporate and soft skill trainers in India who work either full time or as freelance faculty. The companies are gradually realizing the importance of imparting right training to their employees so that they get updated, attuned with latest teaching and training methodologies and developments and stay competent and compete. All companies and especially IT and BPO companies where attrition is high have realized the role of corporate trainers and are hiring them to motivate their employees on continuity basis.

Conducting workshops, seminars and conferences periodically will help the employees release and relive from their routine burdens and monotony and they get recharged by corporate training activities and as a result they contribute the work with more energy and enthusiasm.

3. Organization of Training:

Organization of training is essential as it saves the time and energy and also provides right direction towards effective training. In this context, let us look at the qualities needed for a trainer, tips for trainers, training tips and trainer’s rapport with the trainees.

Qualities of a Trainer:

• He should have passion towards training.

• Should have presence of mind and should have the ability to respond any type of queries.

• Must be a great communicator with the ability to motivate and inspire the audience.

• Should have courage and confidence to face the crowd.

• Should have possessed work experience that helps him to give too many examples based on experience. Along with examples he can teach the skills and abilities which are essential for the trainees.

• Should be a psychologist, if not, should know the pulse of the audience so that he can reach the audience effectively and efficiently.

• Should have higher levels of energy and enthusiasm.

• Should have good sense of humor.

• Should have read many books that provide food for thought for the trainees.

• Should have traveled widely as it develops tolerance towards others’ cultures and values.

• Should have emotional intelligence.

• Should be a good net worker, observer, and listener.

• Should be tactful while handling question and answer session.

• Should be good at presentation skills and interpersonal skills.

Tips for Trainers:

1. Don’t load the entire information at one go. Instead of which give out the information in a piecemeal manner. It is like that of a diabetic patient who takes meals with regular intervals as it helps in better digestion and contains the disease. No session should last for more than 2 hours at one go as the trainees will resist too much intake of information at a time.

2. Give the easy stuff first followed by the tough stuff gradually so that trainees will be able to absorb the contents.

3. Keep relevant case studies and examples under your fold. Apply the same depending upon the context.

4. Keep message oriented stories so that the same can be delivered along with the contents as humans would love to listen to stories. Message oriented stories not only give morals but also inspire the audience to think and apply in real life.

5. Leave your ego at the door. How giant you are is not the yardstick but how effectively you teach and train is the criteria. When you train well the audience will applaud and recognize your abilities and talents and it boosts your ego automatically.

6. Involve the trainees into team games and activities if possible. Research reveals that human would remember 20 per cent of what he listens, 30 per cent of what he sees, 50 per cent of what he listens and sees and 80 per cent of what he listens, sees and does.

7. Always start with a small story or an example or an anecdote and then correlate the same with the training material. It arouses interest apart from creating the best impression.

8. If previous session was held start the session by linking with the previous session as it easily connects the contents and carries the audience in a natural training flow.

9. Lay stress on quality not quantity. Apply the Socratic Method where the answers are found out from the questions raised by the trainees. It also encourages the trainees to think creatively and innovatively. It inspires them to think through training material thoroughly.

Training Tips:

• Avoid jargon. Every field has its own jargon and it is not proper to expect the audience to know a specific jargon. In extreme cases if jargon can not be avoided it is better to explain the jargon then proceed further so that the trainees can get glued to the training process.

• Always use positive strokes that encourage the audience to show interest in the training activity.

• Encourage questions and discussions from the audience.

• Have patience when a few trainees do not show any interest in the session. Apply the tools and techniques so that they can be brought into the training fold actively. In this context, application of humor is essential.

• Tailor the training as per the needs of the trainees to avoid wastage of time, money and energy.

• Appreciate the audience generously.

Trainer’s rapport with trainees:

• The trainer must greet the trainees. And he must start the session with ice breaking activities.

• He must remember the first names of a few trainees to keep the training activity alive and kicking.

• He must encourage informal conversation.

• He must keep the trainees at comfortable posture and encourage the trainees to pair up and familiarize with them.

• He must stick to punctuality and start the session as per the scheduled time.

• Use easy to understand examples.

• He must change his strategies depending upon the response of the trainees. If he finds that particular strategy of training is not working out he should shift his strategy that is acceptable to the maturity level of the trainees.

• He should create an ambience that is conducive for learning and training.

• He should ensure that all the trainees take part in the training process actively. If possible he must offer small gifts to encourage the non-participants.

4. Evaluation of Training:

Hesseling has divided the evaluation of training into four categories – trainee, the trainer, the training experts or directors, and management 9.

It is the last but not the least stage where the amount of hard work that has been put in is evaluated. After the training the feedback forms should be given to the trainees to find out the effectiveness of the training and the competency of the trainer. The feedback questionnaire should have both open ended and close ended questions by which the performance of the training can be evaluated. It will also help the organizers to cover the areas that have been left uncovered in this training activity.

CONCLUSION:

Srinivasan’s study 10 (based on a sample of trainers, trainees, program organizers and sponsors) indicated that in future the following would be the potential areas of training:

• Man Management

• Corporate Planning

• Marketing Management and Sales promotion.

The above information is an indication of the importance of training in those areas in the years to come. It will also help the organizations to find out where the future of the training activities lies.

Training is only a comma not a full stop. With the growing competition across the globe due to the rapid changing technology the concept and process of training is changing and will also undergo drastic changes in the years to come. Out of the four major pillars of an organization such as ‘men’, ‘machine’, ‘material’ and ‘money’ it is the pillar of ‘men’ that plays a crucial role to survive and succeed in the corporate world. It is but natural that we can stay competitive only by effective and efficient training and grooming of precious human resources.

Chicago Suburban Markets for New Homes and Rehabs

Chicago Area Markets for New Homes and Rehabs What are The Next Hot Markets and What you Should Consider Before Buying? By: Christine Moscinski, Broker Associate & Market Expert – Gobber GMAC REAL ESTATE

April 27, 2009 

There’s no doubt that the residential real estate market is slumping in some areas. Many of the hardest hit areas are communities where homes are not kept “up to par” with what is out  in the new development or newly constructed homes and even rehabbed homes.

New competition with emerging housing developments and condo conversions around Chicago’s near West Side Loop, the northeast and southwest suburbs including Huntley, Lemont, Lockport, Romeoville, Bolingbrook, Homer Glenn, New Lenox are amongst the hottest areas right now with homes ranging in the low $200K to upper $300K’s so take advantage of these custom homes (many are in pre-foreclosure or bank owned). All are conveniently located along the I-355 extension, (the new Veterans Memorial Tollway (I-355) from I-55 through Will County to I-80) makes it an easy commute to Chicago.

Affordability and getting a great “deal” is ranked a top priority with my clients – they are looking for the best deals out there. The most asked question is “where can I can find “brand new”, move-in ready or completely rehabbed homes and townhomes for cheap?” – but are willing to pay the extras in monthly assessment costs and longer commute times for a “deal home”.  Frankly, I cannot advise against newer developments or rehabbing when the existing homes are reaching 40-50+ year’s in age, are higher priced (some by $50+K) and homeowners have not made any updates or changes since they were built!

My suggestion has always been Location, Location, Location and of course mass transit availability. With the population growth (estimated to go over nine or ten million by the year 2020 according to census) and current gasoline prices, forecasters see a drastic adjustment to travel in the very near future. Forecasters estimate that we will see many more “green” cars on the road vs. the 20% market share of sales in SUV and van sales and a new or expanding transit system.

And a quick note, just because new retail is rising out of the ground does not mean instant success and equity growth in your neighborhood.  Although it’s great sales tax income for the town, I advise clients to examine their lifestyle and where they see themselves in 5 years. Statistically homeowners stay in a home 5-7 years before moving due to outgrowing the home or the need to relocate for job or other reasons. Therefore, homebuyers should review with their Realtor every aspect of their home purchase, the location, commute times, METRA, PACE or CTA transit lines, taxes, municipal improvements, schools, HO assessments and think down the line what changes may take place in themselves and the area they pick and if they are willing to stay awhile.

There are plenty of opportunities for buyers.  Many young professionals want to live nearer to Chicago and close to mass transit (METRA, CTA, PACE) including Chicago’s Near West Side, Greek Town, Taylor Street & Medical District, but they do come with the higher city tax.  So many do opt for close and affordable neighboring suburbs that are less expensive and have lower real estate taxes like Berwyn, Brookfield and Westchester Illinois.

My top picks for affordable homes in the near west suburbs are: South Berwyn (2 & 3BR from $220k-$280K) Brookfield (2-3 BR from Low $200K’s), Westchester (2BR from the mid $200K),  La Grange Park (2BR from mid to upper $200K), Downers Grove (2-3 BR from low $300-$400K) Illinois. 

Each of these communities offer future growth and low real estate taxes.

With the recent changes and the injection from the government securing interest in U.S. banks  we will see a rebound in lending in 2009.  Mortgage rates are so low many that can afford to buy right now are really taking advantage of this opportunity.

My area picks for pre-rehab homes, pre-foreclosure and REO’s can be found in north & east Berwyn, Cicero and Lyons where the average price of these types of homes start in the low $50-100K with an average investment to rehab $30-$50K. 

My picks for new construction homes and townhomes are: Shorewood, Joliet, Bolingbrook, Romeoville and Elgin where prices start in the low $200K’s for 3-4 bedroom..

The house deal’s are out there, you just have to HUNT for them!

The Race for favourable rates

Apart from the stock market crash and the severing of international credit lines to Nigerian banks, analysts still maintain that the nation is yet to feel a stint of the global financial meltdown. But one part of Nigeria that is definitely been affected by this financial meltdown is the federal government income as its revenue generation capacity has been greatly diminished due to falling oil prices – a fall out of reduced demand for crude. For a country that sold a barrel of crude for $140 a few months ago and now desperately seeking buyers at $45 thereabout, the global financial crisis couldn’t be closer.

The issues that this raises however, is far of greater importance than how much we sell or make from a barrel of oil. It has exposed the inability of successive governments in Nigeria to diversify the Nigerian economy, a once vibrant agricultural economy, from the mono-product, oil dependent economy that it currently is.

Currently, Nigeria generates 80% of its revenue from oil exports and about 90% of its foreign exchange putting the country always at the mercy of crude oil price fluctuations. As the Nigerian economy again cycles down with falling oil prices, the need for the creation of more options for the economy comes to the fore with the government in need of more revenue, more employment for its people and better infrastructure.

Reviving the real sector of the economy, especially the manufacturing sector which serves as the industrial base of the economy and encouraging private enterprise remains a ready alternative for any attempt at diversifying the economy beyond oil exporting. Without any statistical backing it is obvious that real sector growth in Nigeria has been on the negative in the last two decades. Large, small and medium sized industries wind up almost daily. New entrants always find it difficult to survive and close doors as quickly as they opened them.

Various arguments have emerged as to who to blame for this poor showing that has made Nigeria the dumping ground for all kinds of foreign goods. Many would want to support the ‘How can banks be declaring billions of naira in profit when the real side of the economy is in a comatose?’ argument, putting the blame at the doorsteps of banks. The claim is that high interest rates make it impossible for businesses to source cheap funds with which they can run their operations. The managing director of a paint manufacturing company once affirmed this claim during his company’s recovery phase that, any industry that must stay afloat should look away from the banks when it comes to seeking funding in Nigeria.

The need for favourable rates has always therefore, been a source of concern since Nigeria’s oil wealth has been unable to tow the economy to paradise and government has remained inhospitable to entrepreneurship. So, financial regulators representing the government find it expedient to always seek ways of installing a regime of lower, more business friendly rates if Nigeria must again feel economic prosperity.

Since the current CBN governor Chukwuma Soludo came into office in May 2004, he has never hidden his belief that lower inflation rates can play a huge part if banks must begin to lend at more reasonable rates. The inflation rate is the rate of increase in the prices of goods and services. If inflation is high definitely operational costs increase putting pressure on banks to push up rate also.

Apart from spirited attempt to cub inflation, the CBN also adjusts the monetary policy rate in a bid to aid banks’ ability to lend at lower rates. The monetary policy rate is the rate at which the CBN lends to banks. The MPR is also supposed to serve as a regulatory rate around which other rates will be determined. The lower this rate is the better for banks and the better it should be for customers.

The central bank has also, a number of times, tried the option of pegging the rates at which banks must lend to customers.  Most times this measure continues to fail as banks have always lent well above stipulated rates.

But like many bankers, I would not also subscribe to the claim that high interest rates should be considered the monster that has consumed major businesses in Nigeria including Michelin which closed its factories in Nigeria a few years ago. Definitely, there must be more factors affecting the survival of businesses and even the operations of banks themselves and threatens the possibility of ever having rates that will favour business growth for economic buoyancy.

Firstly, the general state of infrastructure in Nigeria is not at all encouraging to businesses. Chief among these infrastructural deficits is the near inexistence of power supply in a country that hopes to be one of the top 20 economies globally by 2020. Power supply in Nigeria remains unreliable so businesses have to run on alternative power, in many cases generators, which are expensive to maintain and keep running. This increases the cost of operations of banks whose branches (they have a huge number of them these days) have to run on generators most times for 24hours a day. As business ventures that are also struggling to survive and deliver profit to their shareholders, the cost of running such expensive operations must be borne by customers. Today banking operations are run on high tech facilities some of which have to be kept in operation always increasing the demand for power.

Security is also a major concern. For banks, which are in the business of money movement, they cannot afford to compromise security. Banks invest huge sums in procuring amoured carriers for moving cash in the face of growing insecurity. Armed robbery attacks on loaded vans are also a rampant occurrence especially in the Niger Delta region. So much also has to go into insurance costs owing to the volatility of the environment.

These two major factors coupled with other factors such as the inflation rate which in spite of continuous efforts at reducing it to one digit is still on the high. Figures from the National Bureau of Statistics show that food prices is fuelling overall increase in inflation rate. This unguarded increase in the cost of goods and services especially food products and its ripple effect on the cost of living impacts negatively on the capacity of banks to reduce interest rates which is their major source of income accounting for up to 80% of revenue making banking operations in Nigeria extremely expensive and leaving interest rates nowhere but at prohibitive levels.

I should not forget to also note, as stated by the First bank managing director, that credit risk is now playing a critical role in determining at what rate banks will lend to any prospect. According to him, the interest rate is a reflection of the risk inherent in the business. So when a bank believes that a venture holds more risk than usual, the interest rate will have to cover for it. In such a business environment as offered by Nigeria, the natural risk inherent in every venture more than doubles. Little wonder that 26% of the industry loan is non-performing.

After a meeting with stakeholders including all bank CEOs about 3 weeks ago, the CBN has taken a number of measures to try to cub the unwarranted rate of interest in an effort to stimulate the economy by increasing liquidity within the system. One of these measures included the lowering of the monetary policy rate to 8%. This review is supposed to encourage banks to borrow from the CBN and lend to customers at better rates. As part of the fallouts of the meeting that focused on the rates, the CBN has also again taken the option of pegging interest rates. Banks are now not expected to lend at above 22% with sanctions spelt out for erring banks. How far this will achieve in the face of the other issues raised remains a question of time.

Abstract

This paper  presents a secure authentication method  for Mobile IPv6. As a default IPsec is used for secure signaling messages between the Mobile Node and other agents in Mobile IPv6 networks. Mobile IPv6 message transactions include the Binding Updates and Acknowledgement messages as well. We propose a new mechanism for securing Mobile IPv6 signaling between Mobile Node and other agents.  The proposed method consists a Mobile IPv6 message authentication option and cookie management that can be added to the current protocols for securing IPV6. Also we investigate an architecture to integrate the mobility authentication signaling. This architecture is implemented and evaluated. In Mobile IPV4 protocol and also some authentication protocols of Mobile IPV6, there are some difficulties for satisfying timing requirements. We show the latency can be decrease between the Mobile IPV6 node, Home Agent and Correspondent Node with creating a cookie file keeping the mobile node identification.

 

1.Introduction

The security of a mechanism and protocol depends on the reliability and infrastructure of the Internet routing. The protocol will work between mobile nodes and any other Internet node that have no previous connection or relation with, and also we assume there is not any specific global security infrastructure. When Mobile IPV6 was developed, the built-in technology made it possible for users to change their points of attachment to the Internet while they still using the same IP connections established before. But, authentication and authorization, which are too important functions in wireless networks, were not considered during the design and creation. Therefore, this paper investigates the integration of MIPv6 and Authentication systems and develops integrated architectures as well. The mechanism described in this paper is a simplified version of the actual Mobile IPV6 protocol. We focus on the binding-update messages sent by the mobile node to its correspondents. In fact authentication service is the most important protection and inspection services in wireless networking. Security designing in mobile network is a critical stage in developing and establishing a Network infrastructure system. While a wireless system provides economic, convenience and efficient network , it must also be secured to prevent attack for theft and damage of data and  information . A safe and secure wireless network can ensure that your data transmissions are not intercepted, abuse, misuse by unknown third-party. Unsecured wireless networks are vulnerable to many types of problems, including:

-Theft of information

-Corruption or illegal modification of data

-Interception of interaction ,transaction and communication

-Insider abusing of network data and resources

Establishing a professional and secure wireless network means implementing a framework of authentication, encryption and key management protocols[1]. We focus on authentication with IPV6  in this paper. As a description , authentication is a process of verifying that a device or user that is attempting to log in to the wireless network, should be allowed on the network. Encryption and Key Management are processes and techniques that are make more complex and scramble data so that an unauthorized user or device that receives the data cannot use that.

 

2. IPv6 Review

Based on the recent concerns over the lack of internet addresses and the desire to provide more functionality for modern mobile devices, an upgrade of the old and current version of the Internet   Protocol (IP), called IPv4, has been established. This new version, called IP version 6 (IPv6), resolves  weakness of IPv4 design issues and made a revolution in Internet in recent years. The long of addresses in IPv6 are 128 bits. The first 64 bit are used for the link prefix. Which it  is assigned to every link and gets advertised through routers on that link. The second 64 bit of the address belongs to the interface  identifier .There are different scopes of IPv6 addresses in networking. The different scopes can be     diagnostic by looking at certain bit patterns of the address prefix.  

We can call the most important scopes in IPv6 as below:

- Link local: An address with a scope of link local only can be used to communicate within the node’s link. Packets with this link addresses will not be

routed outside the link. The first 64 bits of this addresses are fixed and look likes this: 1111111010 0 . . – Site local

First 10 bits Proceeding 54 bits. Link local addresses are like unique addresses  inside a site. The size of a site will define by site administrator. It can be a small home network with two or three clients or even the network of a university with hundreds nodes. The first 64 bits of site local addresses look like follows: 1111111011 0 . . . – Subnet ID

The 16 subnet bits are used to differentiate sites and First 10 bits Proceeding 38 bits last 16 bits. Protocol transitions are not easy and the transition from IPv4 to IPv6 is no exception. Protocol transitions are typically deployed by installing and configuring the new protocol on all nodes within the network and verifying that all node and router operations work successfully. Although this might be possible in a small or medium sized organization, the challenge of making a rapid protocol transition in a large organization is very difficult. Additionally, given the scope of the Internet, rapid protocol transition from IPv4 to IPv6 is an impossible issue. The designers of IPv6 recognize that the transition from IPv4 to IPv6 will take years and that there might be organizations or hosts within organizations that will continue to use IPv4 indefinitely[1]. IPv6 solves the network address limitations of  the current IPv4 protocol by replacing IPv4’s  32-bit addresses with 128-bit addresses. Different elements were considered during the design of IPv6. One of this consideration is forecasting about the needs of future markets. We can guess that future of internet markets would rely on more security, high efficiency, and mobility[7]. Another successful issue of IPv6 designing is the way of internet’s transition from IPv4. This kind of transition involves with different software, hardware, protocol and infrastructure problems. Fortunately IPv6 has been developed to work with IPV4 network protocol as well. By creating a tunnel to transfer IPv6 packets or by creating a tunnel for transferring other protocol packets, IPv6 will support without requiring any fundamental changes. When a mobile node is far from it’s home agent, it sends information about its current location to the home agent. Any node that it wants to start interaction and communication with a mobile node will use the home address of the mobile node for this communication and sending packets. The home agent intercepts these packets information, and via using tunnels the packets to the mobile node’s care-of address. In fact Mobile Network IPv6 uses care-of address .But for supporting route optimization for direct connection between Mobile Node and Correspondent Node, the Correspondent node will use IPv6 header than the IP encapsulation. Mobile IPv6 technology allows a Mobile Node to move within the Internet infrastructure without loosing an old established connection. It means for a Mobile Node to be reachable at any time by a Correspondent Node it must have an address that not change. In fact this address belongs to the subnet of home network. In Mobile IPv6 this address is called, Home Address or HoA. If Mobile Node be available in its home network, all packets that want to reach to it, can reach the through the normal routing way. In this situation the Home Agent is topologically correct for the Mobile Node. But if the Mobile Node moves to another subnet, it must to update a Care of Address that topologically this address belongs to the new network. From now Mobile Node  will not be reachable through its HoA as well. Home Agent is responsible to receive all packets that destined to the Mobile Node, whenever Mobile Node is in another visited network. Whenever Home agent receives a packet, it would establish a tunnel it to the Mobile Node’s current Care of Address. It proves the Mobile Node has to update its Home Agent about its current Care of Address regular. It means Home Agent will forward any packets destined to the Mobile Node’s Home Address, to its current Care of Address in visited network. These packets will send through a tunnel to the Mobile Node. It should be considered that the tunnel begins from the Home Agent and will end at the Mobile Node. Mobile IPv6 works like transparent for upper layers like applications. Any time Mobile Node wants to send a packet to the Correspondent Node, it can send it direct to it’s address.

 

3. Security on Mobile IPV6

 3.1. Data Encryption and authentication protocol

One of the solution for making sure that unauthorized users or systems do not access on your wireless and mobile network is to encrypt your data and files. The famous and basic encryption method, WEP (wired equivalent privacy), unfortunately was found to be completely weak and nonstable. WEP works on a shared key technology, or password, to prevent unauthorized access. Anyone who find the WEP key or even stronger key can join and misuse the wireless network. There is no any mechanism or technique in WEP  to automatically change this key, and some tools have produced that can crack a WEP key very fast , even less that 60 sec! It means it will not take long time for an attacker to access a WEP-encrypted in wireless network. We can say the procedure of  RADIUS server is receiving end user requests, then authenticating the user, and finally providing the NAS plus all of the  information for it to deliver services. This protocol of authentication provides a centralized security system to control access to the network resources. Lightweight Directory Access Protocol or LDAP  is called another authentication protocol which defines organized and accessed information. As we know an authentication protocol is a set of rules for communication between server and clients. By implementing LDAP, Network administrator can control users and clients easier with centralize and secure user information[12]. Also there are other mechanisms for mobile authenticating clients, the combination of  RADIUS, EAP, and LDAP is the most common and available solution in use in business today.  Each component has associated open-source software that is freely available for network administrators to download, configure, and use. Thus, with the hardware in place, installation of an authentication system is inexpensive[15]. 

 

3.2. Hijacking and Spoofing on Mobile IPV6 Networks

The first difficulty of IP networks is that it is difficult to know where information really comes from. An attack called IP spoofing takes advantage of this weakness. Since the source IP address of a packet has no influence to the deliverability, it can easily be changed. The attack – called spoofing – makes a packet coming from one machine appear to come from somewhere else altogether. It’s obvious that IP based address is not trustable at all, because everyone can claims he is the owner of this IP address. Even after authentication step , still everything is not safe against sessions hijacking. It means after identification of a person, we can not make sure he will be the same person during the rest of that session. That’s why all source of data must authenticated during the transmission. Still most of networks in the world are based on Ethernet or cabling LANs. This type of network normally are cheap, globally available, easy understood and fast to expand. But making spying is easy in these networks, because any node is able to read every transmitted packet over the LAN. Formally, each network card only listens and responds to the packets that specifically belongs to it, but it is not difficult to ask these devices to listen all packets during passing on the wire. The first recommendation for all Mobile IP networks is to use encryption and authentication the data. But there are still problems on that. We should consider all encryption keys will be exchanged during communicating parties. It’s a rule that encryption keys use encryption algorithms to encrypt and decrypt data. 

 

3.3. Mobile Node MAC address and Authentication

A sorted care-of address is a care-of address that obtained by mobile node as a local IP address. This IP address will be dynamically acquire, may be through a DHCP server or via a foreign agent. After assigning a routable IP address to MN, the mobile node is now able to establish and communicate directly with it’s home agent, careless of  foreign agent. By implementing of this method, mobility decapsulation has done. Sometimes Mobile Node uses the Mobile Node Identifier option to establish of communication and enable the Home Agent to start using of available authentication infrastructure. One of the most difficult step for an attacker is finding the MAC Address of wireless Lan[7]. Many of systems may trust on a faked MAC address, as an authorized wireless router or client. Attacker can start denial of service attacks by passing access control mechanisms in wireless. MAC addresses have been used as unique layer 2 for network identifier in Mobile IPV6 Networks. As we know MAC address is unique in the world for all network-based devices. Organizationally unique identifiers (OUI) has allocated to all hardware manufacturers specially network products manufacture. Generally the MAC address of a client or mobile node is used as an authentication parameter or a unique identifier for making security in authentication level. When an attacker changes their MAC address they continue to utilize the wireless card for its intended layer 2 transport purpose, transmitting and receiving from the same source MAC. All 802.11 network protocol use their MAC addresses to be changed, with support from the manufacturer[6]. Linux users can change their MAC address with some command or programming with C program. But windows users are able to change  their MAC address by configuring the properties of lan card drivers. We should care that an attacker may choose to change the MAC address for different  reasons[15]. The Mobile IPv6 protocol enables a Mobile Node to move from one network to another network without the need to change its old IPv6 address. Because a Mobile Node is always routable and addressable by its home agent, which is the Mobile Node’s IPv6 address. When a Mobile Node is far from its home network, messages can be routed to it using the Mobile Node’s home address. Normally the movement of a mobile node is completely invisible to transport and other layer protocols. 

 

3.4. Mobile IPV6 Accounting

Mobile IPV6 accounting can be divided to four processes: metering, pricing, charging and billing. Actually the duty of metering process would be measure and collects the resource usage information which is related to a single customer’ service. Also the task of pricing would be the process of determining a cost per unit. Then charging process make compatible the pricing data to the usage of resource to an amount of money that we called charge. This charge has to paid by customer. And billing process obviously  informs customer about the billing information[7]. In fact accounting on Mobile network means the act keeping the records for all user’s usage of the source. The primary aim could be billing for any user but for security reasons we need to know each users logon and logout time, visited websites, amount of download and upload and so on.

 

4. New Mechanism

 4.1.  Mobility Message Authentication with a Cookie File

This section defines a new mechanism in mobility message authentication option that can be use to secure Binding Update and Binding Acknowledgement messages in mobile IPV6 networks. This mechanism is able to used along with IPsec or preferably as an new mechanism to authenticate Mobile node in communication with Home agent or foreign agent to Binding Update and Binding Acknowledgement messages whenever we don’t have IPsec infrastructure in our network. The simulation of the Mobile IPV6 protocols is based on the implementation of Mobile IPV6 in Network Simulator 2 (NS2). Overall implementation is based on home station, correspondent node and mobile agents. In fact base station agent will implement the functionality of home agent and foreign agent. This agent will create the Broadcasting area. This area will re-set every second. Mobile IPV6 agent finds the advertisement and registers with home agent and foreign agent based on protocol. The registration timeout for Mobile IPV6 protocol has set for one second. It means every second updating of registration will happen. For simulation we developed a simulated Mobile IPV6 network that considers to delay and payload.  Also for the simulation of the authentication with a C++ code  home agent will create a cookie file as a identity file. Based on our assumption the Mobile Node has registered with the home agent before leaving it’s subnet. The Mobile Node as a personal computer has some specific details that it can save them in a cookie as a file and then encrypt the file[10]. Home Agent MUST include this option in the BA if it received this option in the corresponding BU and Home Agent has a shared-key-based mobility security association with the Mobile Node[2]. 

 

4.2. New Care-of Address and Binding Update

After detection that a Mobile Node has moved the network, new CoA allowed to access to the network, but it must inform its Home Agent regarding the new location of Mobile Node. It’s a big concern in mobility that whenever a Mobile Node lost it’s connectivity with its last router, until it informs its Home Agent about its new location, all messages that sent to it will lost and also it will not able to send any packet to any of correspondent nodes. Actually a Mobile Node registers its new Care of Address to its HA via sending a binding update message. Then Home agent does acknowledge this update by replying a binding acknowledgement and from that time is able to tunnel the packets from Mobile Node’s home address (HoA) to the Mobile Node’s in new location. In the last step, The Mobile Node informs all of its Correspondent Node, its new location and that it is reachable with this new Care of Address. It means after registering, the Mobile Node sends a BU to all CN to inform them about its new location. By the way, there is an additional procedure for following that BUs are sent to all CNs. This one called Return Routability (RR) test.

  

4.3. WAP Infrastructure with CookiesWAP protocol is a service enabler that is located between internet and mobile networks in the service layer. The service layer includes of different service enablers for mobile nodes and mobile applications. The WAP protocol works like a secured tunnel from the mobile node to the  service layer. All IP packets from a mobile node will transport via three layers of mobile networks: connectivity layer, control layer, and service layer.  

4.4. Design and Implementation

Mobile IPv6 authentication relies fundamentally on IPv6 protocol functions as a standard protocol and IPv6 neighbour discovery as well[1]. It’s obvious that the latency can significantly affect during following components in IPV6 Mobility[13]:

• Movement detection time (td): The time to detection and establishment for Mobile Node, when it moves to a new location. For example the discovery of a new router.

• IPV6 Care-of-Address configuration time (ta):

The time between the establishment of movement and configuration of a globally routable IPv6 address. Duplicate address detection test is partial of this time[2].

• Context establishment time (tc): The time between establishment of a routable care-of address and the establishment of the suitable context state.

• Binding registration time (tr): The time between the sending of a binding update signal to the Home Agent to the receipt of an acknowledged Binding Update.

• Route optimization time (to): The time from registering of new Care of Address to completing route optimization with Correspondent Nodes. This time includes the return routability procedure time if exist, it must calculate before a Binding Update is sent by Mobile Node to a Correspondent Node[8].

In fact , the total Mobile IPV6 configuration delay (th) can be defined as the sum of these mentioned latency times as follows:

Formula 1: th = td + ta + tc + tr + to

  

4.4.1.  Movement Detection Time

The movement of detection time (td) is the sum of two separate latency time: First, Link of switching delay (Tl2) which is the time delay regarding to re-association of the wireless subnet’s Access Point and Second, Link-local IPv6 address configuration delay (Tll), which is the time between the first time that Mobile Node meets a new link by receiving neighbor advertisement over its all nodes. It means movement detection time can be defined as:

Formula 2 : td = Tl2 + Tll

  

4.4.2. Care of Address Configuration Time

As we mentioned about the CoA configuration time (ta), it’s a starting time from the moment of the receipt of a router advertisement till the Duplicate Address Detection and update of the routing table will complete. For stateless IPv6 address auto-configuration ta  is included of the following delays:

Formula 3: ta = TpreAd + TAddConf + TDAD + TRoutUpdt

Meanwhile TpreAd is defined as:

TrtAd – TrtSol (if the router advertisement is requested)

TrtAdInterval / 2 (if router advertisement is cyclic)

TAddConf is the real time that Mobile Node needs to configure the address, like to Create an unique and globally routable IPv6 address. The time in stateful address auto-configuration, like DHCPv6 for Care of address can be defined as:

Formula 4: TAddConf = TDHCPaddReq + TDHCPaddResp + TRoutUpdat

In fact TDHCPaddReq and TDHCPaddResp  will represent the transmission delay caused by stateful configuration of a care of address via a DHCP server in Mobile IPV6 network[9].

 

4.4.3. Care of Address Registration Time

Care of Address registration time or tr is defined as the transmission delay caused within registration of the Mobile Node Care of Address with its Home Agent.

Formula 5: tr = RTMN-HA + BUproc + BAproc

 

5. Create a Code to Perform MPV6 Authentication

On the File menu, point to New, then Project. Click Visual C++ Projects under Project Types, and then we click Mobile Web Application under Templates.

      “In the next step, we should add the following code to the Web.config file:”

  

     

        

           

        

     

  

  

               

 

  

To add a Mobile IPV6 authentication Web Form we should perform these steps:

First, click Add New Item on the Project Menu, then Click on Mobile Web Form and finally type Login.aspx in the Name box.

We can create the following controls from the Mobile IP Controls section

of the toolbox:Collapse this tableExpand this table

Now we can click on Log in and open the code-behind page.

Then we should add the following code in the page:

private void cmdLogin_Clk(Obj sender, Event Args)

   {

      if(IsAuthenticated(txtUsername.Text, txtPassword.Text))

      {

MobileIPAuthentication.RedirectFromLogin(txtPassword.Text,true);

      }

      else

      {

         Error.Text = “Check the credentials”;

      }

   }

 

private IsAuthenticated(String user, String password)

{//Or call the cookie file which has been created for authentication/

   if(FormsAuthentication.Authenticate(user, password))

   {

      return true;

   }

   else

   {

      return false;

    }

}

We can add a Label control on the page, and change the text of the Label control to

“Mobile IPV6 Authenticated!”

 

6. Delay Calculation and analyze

6.1.  Authentication Delay Calculation

In this section, we quantitatively calculate and analyze the times of different phases of authentication on the security and system performance in Cookie ID based authentication and IPsec protocol with some assumption, which is the first step of the work for build up a relationship between the security and QoS[3]. Moreover the effect on the mobility security, authentication mechanism also affects on authentication delay, cost, number of message exchange, call dropping and etc[2]. Data encryption/decryption in each router involves some security processing latencies. We consider that an IPSec Mobile Network in each router take the same time. This latency lsec is evaluated with the following equation:

 Formula 7 :  lsec = Dpacket

                                     R

where Spacket is the data packet size (in bit) and R is the router encryption/decryption processing capability (in bit/s). In our assumption R is 1Mbit/Sec like a normal router. The authentication delay time is defined as the time from whenever  a Mobile Node sends out the authentication request till the time that Mobile Node receives the authentication reply. The problem is during this delay,  any data can be transmitted, which may interrupt or even disconnect the connections. Therefore, the call dropping will increased with the increase of authentication delay time[2]. In the other hand authentication cost is defined as the processing and signaling cost for cryptography. The total number of  messages from the Mobile Node, Foreign Node and Home agent could be large if the distance between them is long[14]. It should be considered, the mobility technique and traffic mechanisms will make the authentication frequently in different scenarios because the authentication will start whenever a Mobile Node establish a communication session.

 6.2. Latency and Analyze Our Mechanism

Practical of Mobile IPV6 is likely to occur where a private network is deployed over the Internet. It means this situation can hint that Foreign Agent belongs to a another subnet wants to provide mobility services. For any accounting and billing purposes, the Foreign Agent needs to track of the usage of its services by mobile nodes. We simulate the Authentication protocol of Mobile IPV6 Transport Mode. Actually the major reason for simulation is representation with the least expensive computational authentication method.  A cookie based authentication is used between the Mobile Node and Home Agent. The second association will establish between Foreign Agent and Home Agent. With the expansion of mobile security protocols and the growth of internets, all networks are trying to securely extend their wireless networks over the public infra-structre, is called Virtual Private Networks or VPN. Cookie identity authentication’s  functionality consists of two phases: In the first phase, mobile node and home agent involved in communication establishment and in the second phase , the home agent and foreign agent will communicate for send/receive the cookie file which is belong to mobile ipv6 node. The major difference between this two phases is that phase 1 will happen in the same subnet and naturally it’s faster and easier to complete, but phase 2 must establish a communication between two different subnet. In phase 2 we recommend  to establish a tunnel for higher security. The attributes of cookie file which is include Mac address, User name, Password and may extra information defined by the encryption algorithm and authentication mechanism. Based on our assumption the maximum authentication message size would be 4096 bytes or 4KB, the transmission delay is considered 40 milliseconds, and we assume 4 Mbps for our mobile network capacity. Also IP Configuration latency on Local Site is around 20 msec and on different subnets this latency would be around 160-200 msec in Cisco standard. As a average it’s considered 180 msec.

Formula 9 : IPconf-latn-local= 20 Msec,

Formula 10 : IPconf-latn-global = 180 Msec

There is an additional factors should be considered. There are additional bytes added to each packet of data sent to control errors and routing information as well. The actual numbers of these codes depend on the packet size and also protocol used in Mobile network. Generally, a typical packet of data sent will be about 90% and 10% or a bit more belongs to overhead. In order to send 4096 Bytes of data about 4506 bytes would actually need to be transmitted.In a router with 16 MegaBITs/Sec speed transfer rate is equal to 2MB/Sec. Our Cookie file with 4506 byte would take time about 0.0023 seconds to send, assuming the source can continuously send the file and also the receiver can process it that fast and there no lost packets that need to be resent. In 802.11X protocol, router will advertise every second. It means in the best case a Mobile Node might wait about 0 Sec and in the worst case it might to wait 1 Sec for next advertising of router and join to it. We assume 0.5 Sec for all cases as a average waiting, whenever a Mobile Node wants to find and ask a router to join to the new subnet.

7. Conclusion

We have described secured authentication Mobile IPv6 mechanism and used in the standard protocol such as IPSec. In Mobile IP network techniques, some features are unconventional because of globally working of protocols and without any global infrastructure for security challenges. The quantitative analysis and design of Mobile IPV6 authentication with respect to the IPSec create more challenges about the authentication in IPV6 wireless networks. Overall time in IPSec in our assumption with 4KB file amd 2MB/Sec router bandwidth is  2.8846 Sec. But in our mechanism with Cookie ID it decreases to  2.2394Sec . It means saving time would be 0.6452 Sec and the efficiency would be “.

Note that we considered latency time for encryption/decryption via a tunnel from HA to CN, and obviously it takes time and cost for our mechanism[11]. We believe without making strong security, any protocol and mechanism on mobility infrastructure will not get a positive response. As result shows encryption/decryption time for Cookie ID file is  0.0325 Sec, that this time will be higher for bigger files. This time has not calculated and mentioned for IPsec protocol, because although it’s strongly recommended on IPSec, but its not a Must[5]. The only disadvantage of Cookie ID mechanism could be creating cookie files on the storage of authenticator server. We can ignore these small files, because as we mentioned the size of cookie file is 4KB. Also task schedule can be configure for disk cleanup monthly, weekly or daily. It can erase these un-useful files from the storage to prevent of any confusing and conflict.

Paris: New faces

The French capital is a tried and trusted destination for meetings and events – but it is still able to surprise. John Keenan reports

You must start with the Seine. The river is the reason the city exists and to this day provides a vital artery to commercial life in the French capital. The touristic Bateaux-Mouches are a familiar sight on the waterway, as inevitable as umbrellas in April, but ship-owner Didier Spade has taken a hackneyed concept and given it a postmodern twist. His Clipper Paris is decked out with sofas, banquettes and armchairs and looks more like a determinedly trendy club than a boring boat. The main and sun decks are 200 sqm each and can comfortably accommodate 100 people for a cocktail reception and 150 people for a seated dinner.

It is an example of how suppliers in Paris are bending traditional formats into decidedly up-to-date forms. Over two freezing days earlier this year, in the tutelary company of Helene Hubert from the Paris Convention Bureau, I was introduced to an array of refurbished, remodeled and restored venues which demonstrated that the French capital is capable of surprising the most proficient Paris planner.  At Cite de l’Architecture et du Patrimoine, opposite the Trocadero, Zoe Macedo, head of events, threaded us expertly through examples of French architecture from the 12th century to the modern age, explaining how the 12 reception rooms and auditorium can be put to use by events and conference organisers. The largest area, the Galerie des Moulages at 3,420 sqm, is more appropriate for a reception rather than anything formal. The Cathédrale area is more manageable at 380 sq m, while the 250 sq m auditorium is a thoroughly contemporary meeting space with all the bells and whistles one would demand.

Across the road on Avenue George Mandel, 6 Mandel is a gorgeous 19th century Parisian townhouse adapted to the needs of the 21st century events planner. The rooms comprise 95 sqm of events space plus a 130 sq m garden within sight and shadow of the Eiffel Tower. I used my imagination and pictured a perfect soiree on a warm’s summer’s eve. The house at 6 Mandel once belonged to Jacques Homberg, Christian Dior’s close companion, and one can imagine the pair shopping for presents at Café Fauchon near the Madeleine. The shop pays homage to all things tasty, tempting and ever-so-slightly transgressive from coffee, condiments and spices to biscuits, patisseries and macaroons… you can practically feel your blood sugar levels heading upwards as you navigate the immaculate aisles. Upstairs a separate terrace is available for meetings of up to 250 people.

Following our visit, Hubert and I worked off the calories with a spirited stroll from the Place de la Madeleine across the Boulevard Haussmann to Rue La Fayette, to see a 120 sqm blank canvass in the heart of the city. Whether L’Appart Lafayette looks elegant, funky or formal is completely down the taste and imagination of the client. Well-suited for product launches and press conferences, this is not the place to bring your dancing shoes – the floor won’t take it. But dancing, playing air-guitar and just about any other form of adolescent exhibitionism is positively encouraged at the ‘rock ‘n’ luxe’ Murano in the Marais area. This is not a hotel, please note: it is an ‘urban resort.’ Meeting rooms are not the top item on the agenda at this property, and if you are the kind of client who balks at the idea of presenting your pitch in a bar-lounge to the accompaniment of a track last heard in Ibiza in the late 90s, then the Murano is not for you. You don’t have to be groovy to stay here, but it probably helps.

Another hip and happening meeting space can be found in the distinctly edgy north-east tip of the city. The Centquatre, a former funeral parlour, is a huge light-filled event space and home to the largest collection of in-house artists in Europe. My visit coincided with a residency by British trip-hop big-wig Tricky and equally as impressive is the 39,000 square metre function space. The publicity material includes much worthy comment about the ‘production of living thought’, but of more practical use are the studios, showrooms and workshops which provide modern meeting and events facilities.

If the artistic innovation at Centquatre is your thing, chances are you will also feel at home in the eccentric environment of the Mama Shelter hotel, close to the Pere Lachaise Cemetery. This property has literally got quirky designer Philippe Starck written all over it – from the ‘provocative’ graffiti in the lift to the comic-book masks and i-Macs in the rooms. Owner Serge Trigano promised me that traditional service values at the 172-room hotel have not been chucked away with the more conventional trappings of comfortable furniture and discreet decorations.

Back on more conventional ground, both literally and figuratively, the Académie Diplomatique Internationale (ADI) on Avenue Hoche, near the Arc de Triomphe and Parc Monceau, is a prestigious location, comprising five separate meeting rooms which can be privatised for up to a total 350 guests. But be warned: you must give plenty of notice as the building normally hosts diplomatic events but can be hired for a few days every month for meetings and special events.

If the accent at the ADI is on the formal, the ambiance at the Païva Restaurant at the foot of the Champs-Élysées is decidedly unceremonious. The former townhouse of a 20th-century courtesan, renovated by renowned interior decorator Jacques Garcia, is a riot of purple and red furnishings – check out the stars on the ceiling. It’s one more instance of how established venues in the French capital are discovering a contemporary twist.

Rooms for improvement

Nestled on the rue de Berri, just off the Champs-Elysees, the Hotel California has no connection with the famous Eagles tune. In fact, the atmosphere is far more Parisian chic than West Coast cool. The 18-room (plus 16 suites) property has nine meeting rooms ranging from the Pasedena 1, which at 25 sqm can hold up to 20 people to the San Francisco II, which has 120 sqm and can accommodate up to 200 people. As sales manager Sylvia Pietsch points out, the property was refurbished in 2004 preserving the comfortable ambience of the old property while installing the thoroughly modern gadgetry that today’s planners insist upon.

Contemporary equipment and spanking new rooms are the dominant themes at the Meridien Etoile. An established player in the Paris meetings market, and now part of the Starwood organisation, the hotel has added two new rooms to its meetings roster: offering 661 and 484 sqm the combined spaces can accommodate up to 1,200 people. The overall meetings offer comprises 25 conference rooms with more than 2,500 sqm of space. Bang opposite the Palais des Congrès, the hotel has 1,025 rooms – chic, it may be; boutique it definitely is not. At the Park Hyatt Paris-Vendôme, all is luxe, calme et volupté. It’s easy to be overawed by the magnificent public areas, festooned with fine art and gorgeous furnishings, but the gracious staff (epitomised during my visit by marketing communications manager Coralie Malazdra) mix a pleasing lack of formality with a practiced professionalism which puts you entirely at ease. The meeting rooms are similarly appealing – 12 all told, from 31 sqm to the beautiful 162 sqm ballroom.

And if you can tear yourself away from the hotel, the best shops in Paris are temptingly on the doorstep – as is the charming Hotel Lotti, tucked discreetly along Rue Castiglione. The property was the brainchild of the Duke of Westminster and the eponymous M. Lotti, one time maitre d’ at the Continental Hotel. Opened in 1910, it retains its old-school atmosphere. Five years ago, the hotel opened a new wing which added 44 bedrooms along with brand new conference facilities. Today the Lotti has eight meeting rooms which can hold up to 100 people. The restaurant – a tasty slice of Italy in the heart of Paris – is also available for group hire.

For my money, the most beautiful hotel ballroom in Paris is located within the InterContinental Paris Le Grand on Rue Scribe. It is one of 21 (count them) meeting rooms ranging from the smallest which can host 10 people for a banquet to the ballroom itself which can hold 600. The hotel is a Parisian landmark – it opened amid much excitement in 1862 and remains a byword for sumptuous events. The Café de la Paix is renowned in its own right.

The Crown Plaza on the Champs-Elysees can’t boast such an illustrious history but what it lacks in heritage it makes up for quirky ambience. This is not your standard Crown Plaza – designed by Bruno Borrione (who, almost inevitably, was a student of Philippe Starck) the property is an eclectic mix of natural timbers and modern furnishings. The 300 sqm meeting room can hold up to 260 people.

Last and far from least, the Westin Paris, overlooking the Tuileries gardens, is a gorgeous grand dame of a property. Rivaling the InterContinental for jaw-dropping opulence, this is an unashamedly upmarket place. The meeting rooms – festooned with frescos in the style of the second empire (that’s 1850-1870 for those whose French history is a little rusty) – the total of 1,982 sqm can hold up to 1,000 people. The Salons Castiglione, Feuillants, Mont-Thabor, Rivoli, and Saint-Honoré provide a variety of configurations for events while the Salons Tuileries and Vendome are best suited for lunch or dinners. The flamboyant is 19th-century Salon Impérial is ablaze with gilt chandeliers, red drapes and carpets while the Salon Concorde is a splendid grand ballroom. Style never goes out of fashion.

Feeding creativity

 Any self respecting event planner has a couple of Paris-based caterers in the address book. If Butard Enescot is not one of them you really ought to do something about it. During a deeply impressive lunch, featuring (among other things) crispy scallops, crayfish mille feuille, lobster marinated in rum and a bitter chocolate truffle, Laetitia Gey outlined the company’s commitment to make each reception ‘a singular moment’. Fine words, but the genuine passion for superlative cuisine was evident in each memorable mouthful. Not exactly a new kid on the block – Butard Enescot was formed in 1997- the company is nevertheless challenging established caterers in the city with dynamism, know-how and supreme skill.

We dined at the beautiful Pavillon Royal in the Bois de Boulogne, and then took a post-prandial stroll to another magnificent events venue, the Pre Catalan. Long a favourite of aristocracy, politicians and high society, the venue is a fabulous choice even if fine dining is not on the menu – it offers 13 elegant rooms ranging from 32 sqm to 800 sqm, and can host from 20 to 1,400 guests for a reception.In contrast to the formalism of the Pavillon Royal, the Boeuf sur le Toit is an unceremonious Art Deco gem in the heart of the city. Le Boeuf wears it brasserie heart on its sleeve and the tables crowded with local families are testament to its enduring appeal. The diners at the Chiberta are also local but likely to be more recognizable to anyone who keeps an eye on the French press. The restaurant’s Michelin-starred cuisine and seemingly bottomless wine list make it a favourite with the powerbrokers, media savvy, famous – and would-be famous.

 A more traditional mainstay of typically French high cuisine, the Lassere is as French as foie gras – and how you react to that idea will tell you whether this establishment will strike you as inspired or insufferable – I plump for the former, won over by the polite and informative staff and the unexpected eccentricity of the sliding roof.On my final evening in the capital Helene Hubert and I dined at La Grande Cascade on the Allee de Longchamp, once more in the Bois de Bologne. A Belle Epoque beauty, the restaurant has a number of private rooms which can be taken over exclusively for groups. We toured the rooms after a lengthy and very Gallic dinner involving game, truffles, and, bien sur, foie ras de canard poivre et sel. Paris has many different faces, but some things never change.

Case study

Toward the end of last year, Paris-based Carlson Wagonlit Travel (CWT) was asked to produce an exceptional event for 80 of the best clients of a well-known financial institution. It was to be an all-inclusive tailormade event; assistance would be provided to each attendee; and the on-site co-ordination would take place in a sophisticated venue renowned for its cuisine.

CWT was charged with end-to-end event management, comprising venue sourcing, delegate welcome, on-site assistance, and around-the-clock service.

The chosen venue was Pavillon Ledoyen.  The Pavillon was built in 1791 by Pierre-Michel Doyen, scion child of a famous catering family. It was redesigned in 1842 and is located amid chestnut trees, beside a manicured lawn and peaceful fountains, within a graceful neo-classical facade.

CWT account director at CWT Meetings & Events in France, Christophe Colvin says: “Our objectives were to create a wonderful experience for these important clients and to introduce new products. The event had to be original and high-end. The delegates were French employees of a large US-headquartered company. For the French people, food is very important – and our presentation reflected this. The delegates were treated like stars; good food, good wine, good conversation.“The budget was dedicated totally to the event – it was not spent on travel or accommodation. By focusing on the clients exact needs we were able to create a memorable event. For me the twin pillars of a successful event are re-invention and creativity.”

A brief word

We asked a leading Paris-based destination management company to respond to a hypothetical brief:  a pan-European company needs to retain staff and strengthen its upscale brand image internally. The programme comprises a two-day conference including break-out sessions, a keynote address by the CEO and a gala dinner on the final evening.

Michele Hensley, Allied France

The arrival and departure transfers can be arranged via different types of vehicles, from de luxe motor coach, van or private car to motorbike transfer. A two-day conference can be enhanced with activities during the morning and afternoon coffee breaks such as distribution of baby trees, massages, caricaturists, cooking activities or a Paris quiz. The activities will be selected according to the demographic of attendees. For the farewell evening dinner, depending on attendees demographic and budget we suggest one of the following: themed dinner in one of the Paris’ pavilions, or a dinner cruise with entertainment to allow the participants to discover the City while dining, or a fun and interactive dinner in the Funfair Museum or lastly the best in terms of classical dinner an evening in the Palace of Versailles, starting with the visit of the state apartments on a private basis for the participants, followed by a dinner in the gallery of battles along with music and period entertainment and costumes.

Vital indicators: Paris

Value for money – 3

Paris ranks with London and New York as a world-class capital – with world-class prices. You don’t have to have a behemoth budget to get the best out of the city – but it certainly wouldn’t hurt.

Infrastructure – 4

The French capital has been drawing crowds ever since Napoleon Bonaparte launched his first European tour. It knows how to cope with groups of all scale and size.

The X-factor -4

Some clients might claim to have seen it, done it and bought the Eiffel Tower t-shirt – but Paris has ways of reinventing itself which should not tax the imagination of the enthusiastic organiser.

Access – 4

Charles de Gaulle is the busiest airport in Europe bar Heathrow – with all that implies. Not the most centrally located hub, which means transfers demand plenty of aforethought. Brits-based in southern England have the option of the Eurostar – a convenient and speedy, if not cheap, alternative.

Luxury Investment – 3

It’s been two year since the Marriott Rive Gauche shook things up with its 60s-style revival. The five-star hotel sector has been pretty quiet since then.

Conclusion

Paris regularly tops the short-haul league tables for most European event planners. It remains well-placed to capitalise on its strengths when its neighbours, and its own, economic fortunes are revived.

Considerable attention has been focused in recent years on the delivery through the oral mucosa of drugs which have a high first pass metabolism (i.e., metabolized to a large extent by the liver during the first pass there through and therefore do not enter the blood stream) or degrade in the gastrointestinal tract. Transmucosal delivery has also been considered for treatment of oral disorders and as a local anesthetic1.

Buccal delivery involves the administration of the desired drug through the buccal mucosal membrane lining of the oral cavity. Unlike oral drug delivery, which presents a hostile environment for drugs, especially proteins and polypeptides, due to acid hydrolysis and the hepatic first-pass effect, the mucosal lining of buccal tissues provides a much milder environment for drug absorption2. Other routes, such as nasal, ocular, pulmonary, rectal, and vaginal drug administration, have provided excellent opportunities for the delivery of a variety of compounds. However, the mucosal lining of the oral cavity offers some distinct advantages.

Mucoadhesive controlled-release devices can improve the effectiveness of a drug by maintaining the drug concentration between the effective and toxic levels, inhibiting the dilution of the drug in the body fluids, and allowing targeting and localization of a drug at a specific site.3

2. Advantages of Buccal Drug Delivery Systems

Advantages of buccal administration are currently recognized commercially or in the medical literature. The first known advantage is rapidity of action. Medications administered buccally enter the blood stream immediately after passage through the buccal mucosa instead of first having to be swallowed and then having to pass through a portion of the gastrointestinal tract before being absorbed. This rapidity of action is one of the reasons that one commercially available and one experimental product for pain relief have been administered via the buccal route. The first of these products contains nitroglyerin, and is available as a buccal pill that adheres to the mucosa, sold under the trademark Nitrogard. The second product contains the non-steroidal anti-inflammatory analgesic diclofenac which has been used in an experimental buccal pill that adheres to the mucosa. The second known advantage of the buccal route is to allow administration of medications which cannot normally be administered orally. Additional unique advantages of the buccal route and the medications that exploit these advantages are described below, as well as additional medications that could be administered buccally to exploit the two previously mentioned advantages of the buccal route4.

As far as the first advantage, rapidity of action, is concerned several classes of medications would have improved efficacy if administered via the buccal route. One class of medications for which rapidity of action is important and which could be placed in buccal tablets in general and the inventive buccal tablet in particular are analgesics which include aspirin, ibuprofen, fenoprofen, sulindac, salsalate, diflunisal, mecleofenamate, naproxen, nabumetone, tolmetin, diclofenac, oxaprozin, indomethacin ketoprofen, choline salicylate, piroxicam, mefenamic acid, etodolac and ketorolac.

As far as the second advantage of buccal administration, the ability to administer drugs that cannot be ingested because of drug destruction, there are several drugs which are potentially in this category. Testosterone could be placed in a buccal tablet and could then be administered via the oral route to avoid destruction via first pass metabolism. Normally such metabolism necessitates the administration of testosterone via injection or a large skin patch worn on the scrotum. However, the scrotal patch has an important potential disadvantage since scrotal skin generates an increased amount of a testosterone metabolite, 5 alpha-dihydrotestosterone that can potentially stimulate prostate hypertrophy.5

Similarly, many drugs affect liver metabolism of other drugs. This affect would be greatly attenuated by administering such drugs in buccal form. One class of drugs in this category are medications that inhibit metabolizing enzymes in the liver resulting in increased concentrations of other drugs. Another class of drugs increases metabolizing enzymes in the liver resulting in decreased concentrations of other drugs. By administering both classes of these drugs using a buccal tablet there would be less effect on the concentration of other drugs and thus the avoidance of toxic as well as sub-therapeutic drug levels. Drugs in the category of liver enzyme inhibitors which could be administered via a buccal tablet include allopurinol, ketoconazole. Drugs in the category of liver enzyme inducers which could be administered via a buccal tablet include cabamazepine, phenytoin, glutethimide, primidone, rifampin and barbiturates such as phenobarbital, pentobarbital, secobarbital,

The third of these advantages of buccal administration is that it results in much less exposure of the GI tract to a drug as opposed to oral ingestions. One of the side effects of many antibiotics is the destruction of normal GI flora resulting in diarrhea and overgrowth with dangerous organisms such as C. difficile. Antibiotics that could be incorporated in a buccal tablet, which would then have enhanced safety because of reduction in the toxic effect on gut flora, include cephlosporins such as cephalexin, cefadroxil, cefaclor, cefamandone, cefuroxime, cefprozil, cefpodoxime, loracarbef and cefixime; also penicillins including penicillin G, penicillin V, cloxacillin, dicloxacillin

The fourth of these advantages of buccal administration is that it allows drugs to be administered which would otherwise interfere with the absorption of other drugs. In particular iron supplements can be administered via a buccal tablet with the avoidance of many adverse effects on the absorption of other medications such as thyroid hormone.

The fifth of these advantages of buccal administration is that it increases the practicality of administering drugs whose absorption is adversely affected by the presence of food. Tetracyclines, in particular, could be administered buccally thus avoiding the effects of food on tetracycline administration which otherwise complicates the administration of this class of antibiotics via the oral route.

The sixth of these advantages of buccal administration is that it allows blood lipids such as cholesterol to be lowered and modified in ways not possible through the oral ingestion of medications. Lipids can be incorporated into a buccal tablet. Lipids absorbed via the buccal mucosa bypass liver metabolism and can directly interact with endogenous lipoproteins thus influencing blood lipid levels. Recently an acute lowering of cholesterol has been demonstrated by applying lecithin to the skin.6

Compared with the oral, nasal, and rectal routes for drug delivery, the buccal route presents advantages such as an efficient blood supply and relatively low enzymatic activity. Moreover, the buccal mucosa is easily accessible and acceptable to patients; it allows the patient to interrupt drug administration by simply removing the drug delivery system. On the other hand, the buccal route is characterized by some intrinsic limitations (barrier properties of the mucosa, small area available for drug absorption, short residence time of the formulation caused by physiologic-removal mechanisms), which have to be considered in the design of buccal drug delivery systems.7

3.3. Factors affecting mucoadhesion in the oral cavity

Mucoadhesive characteristics are a factor of both the bioadhesive polymer and the medium in which the polymer will reside. A variety of factors affect the mucoadhesive properties of polymers, such as molecular weight, flexibility, hydrogen bonding capacity, cross-linking density, charge, concentration, and hydration (swelling) of a polymer, which are briefly addressed below.

3.3.1. Polymer-related factors

3.3.1.1. Molecular weight

In general, it has been shown that the bioadhesive strength of a polymer increases with molecular weights above 100,000 8. As one example, the direct correlation between the bioadhesive strength of polyoxyethylene polymers and their molecular weights, in the range of 200,000 to 7,000,000, has been shown by Tiwari et al. 9

3.3.1.2. Flexibility

Bioadhesion starts with the diffusion of the polymer chains in the interfacial region. Therefore, it is important that the polymer chains contain a substantial degree of flexibility in order to achieve the desired entanglement with the mucus. A recent publication demonstrated the use of tethered poly(ethylene glycol)–poly(acrylic acid) hydrogels and their copolymers with improved mucoadhesive properties 10. The increased chain interpenetration was attributed to the increased structural flexibility of the polymer upon incorporation of poly(ethylene glycol). In general, mobility and flexibility of polymers can be related to their viscosities and diffusion coefficients, where higher flexibility of a polymer causes greater diffusion into the mucus network 11.

3.3.1.3. Hydrogen bonding capacity

Hydrogen bonding is another important factor in mucoadhesion of a polymer. Park and Robinson found that in order for mucoadhesion to occur, desired polymers must have functional groups that are able to form hydrogen bonds 12. They have also confirmed that flexibility of the polymer is important to improve this hydrogen bonding potential. Polymers such as poly(vinyl alcohol), hydroxylated methacrylate, and poly(methacrylic acid), as well as all their copolymers, are polymers with good hydrogen bonding capacity 13.

3.3.1.4. Cross-linking density

The average pore size, the number average molecular weight of the cross-linked polymers, and the density of cross-linking are three important and interrelated structural parameters of a polymer network 11. Therefore, it seems reasonable that with increasing density of cross-linking, diffusion of water into the polymer network occurs at a lower rate which, in turn, causes an insufficient swelling of the polymer and a decreased rate of interpenetration between polymer and mucin 11. Flory 14 has reported this general property of polymers, in which the degree of swelling at equilibrium has an inverse relationship with the degree of cross-linking of a polymer.

3.3.1.5. Charge

Some generalizations about the charge of bioadhesive polymers have been made previously, where nonionic polymers appear to undergo a smaller degree of adhesion compared to anionic polymers. Peppas and Buri have demonstrated that strong anionic charge on the polymer is one of the required characteristics for mucoadhesion 13. It has been shown that some cationic polymers are likely to demonstrate superior mucoadhesive properties, especially in a neutral or slightly alkaline medium 15. Additionally, some cationic high-molecular-weight polymers, such as chitosan, have shown to possess good adhesive properties.

3.3.1.6. Concentration

The importance of this factor lies in the development of a strong adhesive bond with the mucus, and can be explained by the polymer chain length available for penetration into the mucus layer. When the concentration of the polymer is too low, the number of penetrating polymer chains per unit volume of the mucus is small, and the interaction between polymer and mucus is unstable 13. In general, the more concentrated polymer would result in a longer penetrating chain length and better adhesion. However, for each polymer, there is a critical concentration, above which the polymer produces an “unperturbed” state due to a significantly coiled structure. As a result, the accessibility of the solvent to the polymer decreases, and chain penetration of the polymer is drastically reduced. Therefore, higher concentrations of polymers do not necessarily improve and, in some cases, actually diminish mucoadhesive properties. One of the studies addressing this factor demonstrated that high concentrations of flexible polymeric films based on polyvinylpyrrolidone or poly(vinyl alcohol) as film-forming polymers did not further enhance the mucoadhesive properties of the polymer 16. On the contrary, it decreased the desired strength of mucoadhesion 16.

3.3.1.7. Hydration (swelling)

Hydration is required for a mucoadhesive polymer to expand and create a proper “macromolecular mesh” 11 of sufficient size, and also to induce mobility in the polymer chains in order to enhance the interpenetration process between polymer and mucin. Polymer swelling permits a mechanical entanglement by exposing the bioadhesive sites for hydrogen bonding and/or electrostatic interaction between the polymer and the mucous network 11. However, a critical degree of hydration of the mucoadhesive polymer exists where optimum swelling and bioadhesion occurs 13.

3.3.2. Environmental factors

The mucoadhesion of a polymer not only depends on its molecular properties, but also on the environmental factors adjacent to the polymer. Saliva, as a dissolution medium, affects the behavior of the polymer. Depending on the saliva flow rate and method of determination, the pH of this medium has been estimated to be between 6.5 and 7.5 17. The residence time of dosage forms is limited by the mucin turnover time, which has been calculated to range between 47 and 270 min in rats 18 and 12–24 h in humans 19.

Movement of the buccal tissues while eating, drinking, and talking, is another concern which should be considered when designing a dosage form for the oral cavity. Movements within the oral cavity continue even during sleep, and can potentially lead to the detachment of the dosage form. Therefore, an optimum time span for the administration of the dosage form is necessary in order to avoid many of these interfering factors 20.

4. Buccal drug delivery systems

Bioadhesive polymers have been used extensively in buccal drug delivery systems to provide dosage form retention. Bioadhesive polymers are defined as polymers that can adhere to a biological substrate. The term mucoadhesion is applied when the substrate is mucosal tissue 21. Diverse classes of polymers have been investigated for their potential use as mucoadhesives. These include synthetic polymers such as monomeric _ cyanoacrylate 22, polyacrylic acid 23, hydroxyl propyl methylcellulose 24, and polymethacrylate derivatives 25as well as naturally occurring polymers such as hyaluronic acid 26and chitosan 27. Other synthetic polymers such as polyurethanes, epoxy resins, polystyrene, and natural-product cement also have been extensively investigated 28. In general, dosage forms designed for buccal administration should not cause irritation and should be small and flexible enough to be accepted by the patient. These requirements can be met by using hydrogels. Hydrogels are hydrophilic matrices that are capable of swelling when placed in aqueous media. Normally, hydrogels are cross-linked so that they will not dissolve in the medium and will absorb only water. When drugs are loaded into these hydrogels, as water is absorbed into the matrix, polymer chain relaxation occurs and drug molecules are released through the spaces or channels within the hydrogel network. In a broader meaning of the term, hydrogels also would include water-soluble matrices that are capable of swelling in aqueous media; these include natural gums and cellulose derivatives.

Over the last few decades’ pharmaceutical scientists throughout the world are trying to explore transdermal and transmucosal routes as an alternative to injections. Among the various transmucosal sites available, mucosa of the buccal cavity was found to be the most convenient and easily accessible site for the delivery of therapeutic agents for both local and systemic delivery as retentive dosage forms, because it has expanse of smooth muscle which is relatively immobile, abundant vascularization, rapid recovery time after exposure to stress and the near absence of langerhans cells. Direct access to the systemic circulation through the internal jugular vein bypasses drugs from the hepatic first pass metabolism leading to high bioavailability. Further, these dosage forms are self-administrable, cheap and have superior patient compliance. Developing a dosage form with the optimum pharmacokinetics is a promising area for continued research as it is enormously important and intellectually challenging29.

5. Buccal mucoadhesive dosage forms

Buccal mucoadhesive dosage forms can be categorized into three types based on their geometry. Type I is a single layer device with multidirectional drug release. This type of dosage form suffers from significant drug loss due to swallowing. In type II devices, an impermeable backing layer is superimposed on top of the drug-loaded bioadhesive layer, creating a double-layered device and preventing drug loss from the top surface of the dosage form into the oral cavity. Type III is a unidirectional release device, from which drug loss is minimal, since the drug is released only from the side adjacent to the buccal mucosa. This can be achieved by coating every face of the dosage form, except the one that is in contact with the buccal mucosa.

Buccal dosage forms can also be classified as either a “reservoir” or “matrix” type. In the reservoir type, an excessive amount of the drug is present in the reservoir surrounded by a polymeric membrane, which controls the drug’s release rate. In the matrix-type systems, the drug is uniformly dispersed in the polymer matrix, and drug release is controlled by diffusion through the polymer network.

In addition, the mucoadhesive tablet was generally well-tolerated and caused fewer incidences of gastrointestinal disorders and drug-related adverse events than those observed when ketoconazole was administered systemically. The authors suggested that this particular dosage form is the first and only once-daily topical treatment option for this condition 30.

5.1 Buccal tablets

Tablets have been the most commonly investigated dosage form for buccal drug delivery to date. Buccal tablets are small, flat, and oval, with a diameter of approximately 5–8 mm 31. Unlike conventional tablets, buccal mucoadhesive tablets allow for drinking and speaking without major discomfort. They soften, adhere to the mucosa, and are retained in position until dissolution and/or release is complete. These tablets can be applied to different sites in the oral cavity, including the palate, the mucosa lining the cheek, as well as between the lip and the gum. Successive tablets can be applied to alternate sides of the mouth. The major drawback of buccal bioadhesive tablets is their lack of physical flexibility, leading to poor patient compliance for long-term and repeated use.

5.2 Buccal patches

Patches are laminates consisting of an impermeable backing layer, a drug-containing reservoir layer from which the drug is released in a controlled manner, and a bioadhesive surface for mucosal attachment. Buccal patch systems are similar to those used in transdermal drug delivery. Two methods used to prepare adhesive patches include solvent casting and direct milling. In the solvent casting method, the intermediate sheet from which patches are punched is prepared by casting the solution of the drug and polymer(s) onto a backing layer sheet, and subsequently allowing the solvent(s) to evaporate. In the direct milling method, formulation constituents are homogeneously mixed and compressed to the desired thickness, and patches of predetermined size and shape are then cut or punched out. An impermeable backing layer may also be applied to control the direction of drug release, prevent drug loss, and minimize deformation and disintegration of the device during the application period.

5.3 Buccal films

Films are the most recently developed dosage form for buccal administration .Buccal films may be preferred over adhesive tablets in terms of flexibility and comfort. In addition, they can circumvent the relatively short residence time of oral gels on the mucosa, which are easily washed away and removed by saliva. Moreover, in the case of local delivery for oral diseases, the films also help protect the wound surface, thus helping to reduce pain and treat the disease more effectively. An ideal film should be flexible, elastic, and soft, yet adequately strong to withstand breakage due to stress from mouth movements. It must also possess good bioadhesive strength in order to be retained in the mouth for the desired duration of action. Swelling of film, if it occurs, should not be too extensive in order to prevent discomfort.

5.4 Buccal gels and ointments

Semisolid dosage forms, such as gels and ointments, have the advantage of easy dispersion throughout the oral mucosa. However, drug dosing from semisolid dosage forms may not be as accurate as from tablets, patches, or films. Poor retention of the gels at the site of application has been overcome by using bioadhesive formulations .Certain bioadhesive polymers, e.g. poloxamer 407 32, sodium carboxy methylcellulose 33, carbopol, hyaluronic acid, and xanthan gum, undergo a phase change from a liquid to a semisolid. This change enhances the viscosity, which results in sustained and controlled release of drugs. However, these polymers have been investigated for this purpose primarily in ocular drug delivery.

Conclusion

The buccal mucosa offers several advantages for controlled drug delivery. The mucosa is well supplied with both vascular and lymphatic drainage; first-pass metabolism in the liver and presystemic elimination in the GI tract is avoided. The area is well suited for a retentive device and appears to be acceptable to patients. With the proper formulation and dosage form design, the permeability and the local environment of the mucosa can be controlled and manipulated to accommodate drug permeation. Buccal drug delivery is a promising area for systemic delivery of orally inefficient drugs as well as an attractive alternative for noninvasive delivery of potent peptide and perhaps protein drug molecules. However, the need for safe and effective buccal permeation and absorption enhancers is a crucial component for a promising future in the area of buccal drug delivery. A rational approach to dosage form design requires a complete understanding of the physicochemical and biopharmaceutical properties of the drug and excipients. Advances in experimental and computational methodologies will be helpful in shortening the processing time from formulation design to clinical use.

How The Theme Park Wars Will Help You Afford The Family Vacation

Summer is here, the kids are out of school, the economy is in the dumps, and Mickey Mouse wants your money! Don’t count out the family theme park vacation just yet. It is still possible to see the new rides and stay within your budget.
This year, Disney hopes that you’ll bring the family to see their newest attraction, Toy Story Midway Mania. The new ride has just opened on both costs and reviews are generally very positive. In a normal year, tens of thousands of families would hop in the mini van or cram into coach to visit Mickey and friends and see the newest attraction. But this isn’t an ordinary year.
Gas is at a record high, airline tickets have gone through the roof and many regular flights have been dropped – add to that a weakened economy and you have a recipe for lackluster attendance at the theme parks this year. A one day adult ticket at Disney World is currently $71 ($116 if you add the ability to “hop” between parks on the same day), that’s a lot of money in any economy. The price goes down for each additional day that you purchase, but there are also expensive meals and hotel rooms to buy as well. It isn’t going to be a cheap trip.
Disney isn’t the only one that wants your money. Universal Studios parks in both Florida and Hollywood have also opened new family attractions, themed to the Simpson’s TV show. The new Simpson’s ride is bright, colorful, funny, and receiving great reviews from guests. A one day ticket to Universal Orlando is $71 for an adult and $79 if you would like to “hop” between the two Universal Orlando parks. While still expensive, Universal is generally less expensive than Disney and offers lower priced dining options on the whole.
The marketing teams of both companies are in a battle to convince you to visit the parks. But hotel bookings in the Orlando area are projected to be soft through the end of the year and as the number of potential visitors to the various parks starts to shrink, Disney, Universal, Sea World, and a host of smaller parks and attractions will need to wage war with each other to capture the smaller number of tourist dollars. Keep your eyes open for offers of lowered hotel room rates, dining plans, and ticket discounts – all aimed at luring you into the arms of a fuzzy mouse or plastic Homer.
If you have a little money set aside, this is the perfect time to take that theme park trip. While expensive, you can save lots of money on your family vacation by planning and doing the following:
1) Look for attractions and parks within driving distance of your home to save on the air fare.
2) Check online for discounts on tickets and hotels. Packages and discounts are available for both theme park owned properties and less expensive Off Property hotels. Search planning sites such as MiceChat and discount ticket sites such as OrlandoFunTickets to save yourself a bundle.
3) Consider visiting smaller less-expensive attractions which might take up a day or two of your trip and which can help lower the total number of days that you would need to buy more expensive theme park tickets.
4) Ask about meal plans and refillable soda mugs (both of which are offered from time to time by the various parks and/or hotels).
5) Consider eating a big breakfast before arriving at the parks for the day and then leaving the parks to have dinner at the less expensive restaurants which surround the resorts. Lower cost snacks are much easier to afford at the parks than pricey meals.
6) Make sure you are buying the lowest cost ticket. Parks often promote the more expensive ticket (in Disney’s case the “Park-hopper”) but less expensive options (such as a single park ticket) often exist and can save you a lot of money.
7) Avoid the busiest weekends. The fewer rooms that a hotel has booked, the lower the rate you can usually get. In addition, the parks are MUCH more enjoyable when they are less crowded.
8) Consider pushing the family vacation into the fall instead of the summer. Once the summer crowds have gone, the real discounts will begin to show up. If you can swing the time from work and can take the kids out of school, this could be a huge savings for you.
9) Ask the kids. Too many families embark on the big family trip without consulting the kids on the agenda first. Find out what they really want to do. Give them some options. List out all of the parks and attractions in town and have them pick the ones that they’d like to visit. You might be surprised to find out that they would rather visit the less expensive zoo or Legoland than the more expensive Disneyland or Universal Studios. At the very least, you can help pad the trip with a few less expensive days. But you won’t know until you’ve had a family meeting.
10) Know your budget. How much do you have to spend? Then price out the trip: hotel, travel (air or car), tickets, meals, souvenirs. If it adds up to more than your budget, start cutting things out. Keep in mind that trips almost always cost more than you expected (fees, tolls, taxes, etc). Don’t even consider making the trip until you know what you have to spend. This is the ultimate key. It will reduce your stress and allow you to be comfortable knowing that you can in fact afford the trip you are about to take.
It is possible to see the newest rides and attractions, have a great time with the family, and still keep your vacation within the budget. You’d be surprised how many things you can cut from a vacation (that you won’t even miss) to make it affordable.
Woody, Buzz, Bart, Marge, Homer, and Shamu are eagerly waiting for you.
