Following an opening chapter by the late Susumu Ohno on paralogues of sex-determining genes, the five best-studied genes essential for early mammalian gonadal development are portrayed in detail: SF-1 and WT1 and their roles in early events in gonadal development, SRY and SOX9 in testis determination, and the anti-testis gene DAX-1. Subsequent chapters look at the roles of these genes in sex determination in marsupial mammals, birds, reptiles, amphibians and fish, and review the different sex-determining mechanisms, genetic and environmental, that operate in these different vertebrate classes. Two insights emerge: one, that the same basic set of genes appears to operate during early gonadal development in all vertebrates, despite the differences in mechanisms; the other, that sex determination in vertebrates results from a complex network of regulatory interactions and not from a simple hierarchical cascade of gene actions.

Essay from the year 2004 in the subject Communications - Journalism, Journalism Professions, grade: 1,0, Indiana University (School of Journalism), course: Journalism J650, 5 entries in the bibliography, language: English, abstract: Robert A. Gross begins his article Markets, Magazines, and More with reference to a quote from Ellen Gruber Garvey’s book The Adman in the Parlor: Magazines and the Gendering of Consumer Culture which summarizes quite well the essential reason behind many developments that led to the creation of an American mass market. “Why...do men make magazines? To sell ad. space in them. What’s a magazine? So many pages of ad. space.” According to Gross magazines were not so much about content as they were about the advertisements in them. Of course, magazines had to be sold in order for people to read the ads, but the content of the magazine was not designed to improve the reader’s life but to get him interested in the product and eventually make him buy it. Many scholars such as William Leach see this development in the American media landscape from a purely informational and even missionary character to a consumption and marketing based arena as a major move away from the traditional values of media outlets such as the newspaper and others. Leach evaluates this change in his book The Land of Desire where he takes a close look at the changes within the American culture and market. He argues that in the decades after the Civil War “American capitalism began to produce a distinct culture, unconnected to traditional family or community values, to religion in any conventional sense, or to political democracy. It was a secular business and market-oriented culture [...].” He traces this change from the time of the Protestant settlers and early American community life, where the ultimate fulfilment was salvation, spiritual blessings for all and an end to poverty, to the 1900s, where those religious ideals were increasingly transformed and commercialized into personal satisfaction and individual pleasures and profit. With the appearance of “new pleasure palaces” such as department stores, theaters, restaurants, hotels, dance halls, and amusement parks Americans experienced the joy of personal satisfaction. Whereas in the past, Leach writes, “values had taken their character from ... the church; now they were deriving it from business and consumption.” This democratization of individual desire of the post Civil War culture is probably one of the “most notable contributions to modern society” according to Leach.
Seminar paper from the year 2006 in the subject American Studies - Miscellaneous, grade: 1,3, Free University of Berlin (John F. Kennedy Institut), course: Rise to Power: US Foreign Policy in the 20th Century, 24 entries in the bibliography, language: English, abstract: No area seems to be of more importance in the field of foreign policy and diplomatic history today than the so called Middle East. The continuing clashes between Israeli forces and Palestinian suicide bombers, the difficult challenge of stabilizing a newly elected government in Iraq and the growing tension between Iran and the international community concerning the issue of nuclear power are just a few examples which illustrate the urgency to look at origins of these conflicts. As an example for this essay, I have chosen the case of Iran. I will focus on the very beginning of the involvement of the United States in the Middle East, and I will demonstrate what kind of issues and perceptions played an essential role in the determination of U.S. policy towards Iran. Although I do not attempt to find causes for the current situation, some of the factors I will identify in this essay might also serve as an explanation for the current conflict with Iran. Yet, this is not my primary intention and further research and empirical data will be required to investigate connections to the contemporary situation with Iran. However, I will argue that the way US policymakers viewed their Iranian counterparts did not change fundamentally for many decades at least regarding the country of Iran if not more countries in the Middle East. I downplay this aspect because a lot more research is needed to support this argument and it would extend beyond the scope of this essay. Mostly the dealings with Iran and its premier Muhammad Musaddiq in the early 1950s at the time of the Anglo-Iranian oil crises will be of relevance. The essence of my argument is that even though strategic thinking and the fear of a communist takeover of Iran played a role in negotiating with Iran, the reason why Musaddiq was toppled by the CIA and the British MI-6 was because Western diplomats had a so called “orientalist” mindset and perceived him as too weak and irrational as to fight off Soviet attacks and propaganda which could have led to an eventual takeover of Iran by Soviet forces. In order to pre-empt that, the United States and Britain collaborated to bring down Musaddiq and install a shah regime that would, on the one hand be more favourable to Western oil interests, and on the other hand more resistant regarding possible Soviet invasion efforts.
