" They also looked at what they perceived as naturally-occurring "historical control groups" where two events, similar in their relevant properties but differing in the expected media attitude towards them, are contrasted using objective measures such as coverage of key events (measured in column inches) or editorials favoring a particular issue (measured in number). Finally, the authors examine what points of view they believe are expressed in the media . In one case, the authors examined over fifty of Stephen Kinzer's articles about Nicaragua in the New York Times. They criticize Kinzer for failing to quote a single person in Nicaragua who is pro-Sandinista and contrast this with polls that Chomsky and Herman cite as reporting a 9% support for all the opposition parties taken together. Based on this example and select others, the authors conclude that such a persistent bias can only be explained by a model like the one they advocate. Applications Since the publication of Manufacturing Consent, both Herman and Chomsky have adopted the theory and have given it a prominent role in their writings, lectures, and theoretical frameworks. Chomsky, in particular, has made extensive use of its explanative power to lend support to his own interpretations of mainstream media attitudes towards a wide array of events, including the following: Gulf War (1990) Panama invasion (1989) Iraq invasion (2003). Model Home Virtual Tour Herman, seeking to build upon a more institutionalized framework to analyze mainstream media functioning, joined the media watchdog group Fairness and Accuracy in Reporting (FAIR), which has as its goal the critique, documentation, and statistical analysis of what it alleges is media bias and censorship since 1986. With the emergence of the World Wide Web as a cheap and potentially wide-ranging means of communication, a number of independent websites have surfaced which adopt the propaganda model to subject media to close scrutiny.

" One attempt to address the first defect is known as grand unification. The so-called grand unified theories (GUTs) hypothesized that the SU(3), SU(2), and U(1) groups are actually subgroups of a single large symmetry group. At high energies (far beyond the reach of current experiments), the symmetry of the unifying group is preserved; at low energies, it reduces to SU(3)×SU(2)×U(1) by a process known as spontaneous symmetry breaking. The first theory of this kind was proposed in 1974 by Georgi and Glashow, using SU(5) as the unifying group. A distinguishing characteristic of these GUTs is that, unlike the Standard model, they predict the existence of proton decay. In 1999, the Super-Kamiokande neutrino observatory reported that it had not detected proton decay, establishing a lower limit on the proton half-life of 6. 7× 1032 years. Model Home Tour This and other experiments have falsified numerous GUTs, including SU(5). Another effort to address the first defect has been to develop Preon models which attempt to set forth a substructure of more fundamental particles than those set forth in the Standard Model. "
