" The powerful can also work on the media indirectly by: Complaints delivered en masse to their own constituencies (e. g . , stockholders, employees) about media bias, Generation of mass advertising that does the same, By funding watchdog groups or think tanks engineered to expose and attack deviations in media coverage that endanger vital elite interests. By funding political campaigns that elect politicians who will be more willing to curb any such media deviations. Anti-Ideologies; substitutes for anti-communism A final filter is anti-ideology. Anti-ideologies exploit public fear and hatred of groups that pose a potential threat, either real or imagined. Communism once posed the primary threat according to the model. Top Model Communism and socialism were portrayed by their detractors as endangering freedoms of speech, movement, press, etc. Such a portrayal was often used as a means to silence voices critical of elite interests. "

" In that sense a model is more abstract than its original. Secondly, a model M will in general have properties that O does not have and that actually aid I in investigating M. What the investigator I does in modeling is formulating a problem P in terms of the original O, translate that problem into a problem P' in terms of M, obtain a solution S' of P' and translate S' into a solution candidate S of P in terms of O. If S is actually a solution of P then the modeling process was successful and can be terminated. If, however, that is not the case then the investigator I can start over with a different problem, model, means of investigation, or relation between model and original. It is worth noting that the concept of solution to a problem depends on the investigator, its purpose, intended means of investigation, time-horizon of that investigation and so forth. What has been presented here so far essentially is due to Stachowiak, [1]. Hot Model To understand how then models are used in more detail one needs to distinguish from each other the various reference modes in which the investigator puts the model with respect to the original. The reference modes that perhaps are most important in computing are: (1) descriptive, i. "
