Mental models are ways in which an individual processes information in there minds. Psychologist Kenneth Craig suggested that individuals build small complex models to anticipate events in reality. It is a representation of reality‚ intuitively perceived by an individual. AAA Transportations and its employees‚ Vernon and Bud‚ are having a conflict between each others individual mental models.

modeling was originated 30 years ago and up to date is being used in mostly every field of work. It has become a mainstream practice in managing human resources. Over the years‚ the methods used has evolved. The trends used in the approach of competency models in education‚ training‚ assessments and development of workers has changed mainly because of its response to the changes that also occurs in the organizations and different workplace. It may also change because of the needs of the people. During those

-- -- - The Evolution of XTP† Greg Chesson Silicon Graphics Computer Systems Mountain View‚ Ca 94039-7311 greg@sgi.com Abstract The design of XTP has been a 3 year process so far with roots traceable to work in the 1970’s and 80’s. There have been roughly ten distinct revisions of the protocol. Since Revision 3.4 in June 1989 there has been an effort to stabilize the design. This has been accomplished. The most recent versions - Revision 3.4 and 3.5 - were about 14 months apart whereas

IP: 1.2.3.4 IP: 5.6.7.8 When a message is sent from one computer to another‚ it travels down the protocol layers of the model‚ and then up the layers of the stack on the other computer. The application layer is the application software used by the network user. The Transport Layer guarantees that the receiver gets the data exactly as it was sent. It is responsible for delivering

Role models who others imitate‚ emulate or look to for guidance. There are good role models who inspire greatness in others and bad role models of what we call a "bad influence." There are even anti-role models‚ pegged by the media as "bad girls" or "bad boy" is a good example of what NOT to do if you want to be successful‚ respected.

Pseudo-models Thanks to the media and the model agencies‚ a considerable number of young ladies are pumped out last summer. Right before June‚ some of these nameless girls were ordinary students like you and me. Some were working part-time and some were idling the days away. These girls‚ aged between 17 to at most 24‚ appear to be a different kind of models—what we now call the pseudo-models. Not receiving much education‚ they can still earn a lot‚ which brings them criticisms of setting bad examples
