Such conglomerates frequently extend beyond traditional media fields, and thus have extensive financial interests that may be endangered when certain information is widely publicized . Thus, according to this reasoning, news items that most endanger the corporate financial interests that own the media will face the most bias and censorship. The authors claim that the importance of ownership filter is the fact that corporations are subject to shareholder control in the context of a profit-oriented market economy. The theory then argues that maximizing profit means sacrificing news objectivity, and news sources that ultimately survive must be fundamentally biased, with regard to news in which they have a conflict of interest.

" 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. For an investigator I it makes only sense to consider an entity M as a substitute of an entity O, if I can (1) establish an analogy, similarity, or similar relation between M and O that permits the substitution of O by M with respect to purpose and means, time-horizon etc. , and (2) I can actually investigate M in the required way. That implies firstly that M does not have the properties of O that prevent I from investigating O. Also other properties of O may not be properties of M. Architectural House Model Kit 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. "
