" Models are usually man-constituted. That justifies talking about their purpose prior to talking about their consistency . Models are used as substitutes for originals because properties of the latter are of interest and the originals are not going to be investigated themselves. There may be a number of reasons for that such as taboos preventing from studying the original itself, or inability, the involved cost in terms of resources or moral damage being intolerable, or similar.

That implies firstly that M does not have the properties of O that prevent I from investigating O. Beautiful Female Fitness Model Also other properties of O may not be properties of M. In that sense a model is more abstract than its original. "

Figure Fitness Model The theory postulates five general classes of "filters" that determine the type of news that finally gets published in news media. These five are: Ownership of the medium Medium's funding sources Sourcing Flak Anti-communist ideology The first three (ownership, funding, and sourcing) are generally regarded as being the most important.
