" The consistency of models may be conceptual or physical. In many areas of research conceptual models have become the dominating species, as conceptual models, more easily than physical ones, can be investigated by means of computing . For conceptual models to be the shared property of a research community the concepts they involve must be capable of being shared. That is the case when a consensual understanding of these concepts has been achieved or can be achieved by means of definition, examples, etc. With respect to what is shown by a conceptual model there are differences at least with respect to computer science, mathematics and logic. Mathematical models in one way or another establish a functional cohesion between entities such as input values and output values. Logical models establish an interpretation relationship between formulae and structures. Car Collectible Model Models in Computer Science are largely organizational in that they show how data, a cooperation between agents, the process of creating a response to an external stimulus, an algorithm, or similar is structured. The emphasis of organization that is apparent in many models of computer science appears to be a consequence of either of the following: (1) complexity issues need to be dealt with such that a functional cohesion actually can be evaluated.

" Journalists are then supposed to adopt an uncritical attitude that makes it possible for them to accept corporate values without experiencing cognitive dissonance. During the year 2005 in the USA, the Government Accountability Office (GAO) criticised the George W. Bush administration for the preparation and distribution of videos which falsely give the impression of being interviews made independently of the administration. The New York Times claimed that more than 20 federal agencies, including the State Department and the Defense Department, now create fake news clips. The Bush administration spent $254 million in its first four years on contracts with public relations firms, more than double the amount spent by the Clinton administration. [1] [2] Flak The term "flak" has been used to describe what Chomsky and Herman see as targeted efforts to discredit organizations or individuals who disagree with or cast doubt on the prevailing assumptions which Chomsky and Herman view as favorable to established power (e. g. Car Magazine Model, "The Establishment"). Unlike the first three "filtering" mechanisms — which are derived from analysis of market mechanisms — flak is characterized by concerted and intentional efforts to manage public information. "
