Genetics and the population history of Europe

Analysis of genetic variation among modern individuals is providing insight into prehistoric events. Comparisons of levels and patterns of genetic diversity with the predictions of models based on archeological evidence suggest that the spread of early farmers from the Levant was probably the main episode in the European population history, but that both older and more recent processes have left recognizable traces in the current gene pool.

Prevalence of germ-line mutations in p16, p19ARF, and CDK4 in familial melanoma: analysis of a clinic-based population.

Five to ten percent of individuals with melanoma have another affected family member, suggesting familial predisposition. Germ-line mutations in the cyclin-dependent kinase (CDK) inhibitor p16 have been reported in a subset of melanoma pedigrees, but their prevalence is unknown in more common cases of familial melanoma that do not involve large families with multiple affected members. We screened for germ-line mutations in p16 and in two other candidate melanoma genes, p19ARF and CDK4, in 33 consecutive patients treated for melanoma; these patients had at least one affected first or second degree relative (28 independent families). Five independent, definitive p16 mutations were detected (18%, 95% confidence interval: 6%, 37%), including one nonsense, one disease-associated missense, and three small deletions. No mutations were detected in CDK4. Disease-associated mutations in p19ARF, whose transcript is derived in part from an alternative codon reading frame of p16, were only detected in patients who also had mutations inactivating p16. We conclude that germ-line p16 mutations are present in a significant fraction of individuals who have melanoma and a positive family history.

The International Human Rights Policies of New Democracies: Brazil and Chile in Comparative Perspective

Since the beginning of the 1990s, the majority of Latin American states have attempted to incorporate in some way or another human rights concern into their respective foreign policies, highlighting a history of human rights abuses and the return of democratic political rule as a trigger for galvanizing a commitment to assist in preventing such violations in other countries. Yet, while human rights have come to play a non-trivial role in the contemporary foreign policy of many Latin American states, there is great diversity in the ways and the extent to which they go about incorporating human rights concerns into their foreign policies. Explaining the diversity of human rights foreign policies of new Latin American democracies is at the heat of this project. The main research questions are the following: Why do new democracies incorporate human rights into their foreign policies? And what explains the different international human rights policies of new democracies? To answer these questions, this research compares the human rights foreign policies of Chile and Brazil for over two decades starting from their respective transitions to democracy. The study argues that states commitment to international human rights is the result of the intersection of domestic and international influences. At the international level, the search for international legitimacy and the desire for recognition and credibility affected the adoption of international human rights in both cases but with different degrees of impact. International values and pressures by themselves, while necessary, are an insufficient condition for human rights initiatives perceived to have not insubstantial political, economic or strategic costs. New democracies will be more or less likely to actively include human rights in their international policies depending on the following four domestic conditions: political leadership legitimizing the inclusion of human rights into a state's policies, civil society groups connected to international human rights advocacy networks with a capacity to influencing the foreign policy decisions of their government, and the Foreign Ministry's attitudes towards international human rights and the degree of influence it exercises over the outcome of the foreign policy process.

“Fall” and Redemption in the Thought of Martin Heidegger and Jacques Lacan

This dissertation examines and develops Martin Heidegger’s concept of “falling” as a significant historical-philosophical principle. Falling, however, is primarily understood as a concept of the early Heidegger, whereas I argue that Heidegger continues to rely upon it, both explicitly and implicitly, throughout his career. Falling is a description ofphilosophical and Western history, known as metaphysics, and the description of man’s relationship to Being. Thus, falling relates to the most significant streams in Heidegger’s later thought, too, including the truth of Being, the death of God, the gods, the overcoming of metaphysics, and meditative thinking. I then reinterpret the traditional theology of the Fall narrative from Genesis in light of falling as philosophical concept, extending Heidegger’s own “destruction” of Western metaphysics in relation to one of its grounding myths. I move on to demonstrate the significance of a falling understanding in a rereading of the death of God and the end of metaphysics by examining Heidegger’s engagement with Nietzsche. I conclude by incorporating Jacques Lacan’s psychoanalysis as a further extension of Heidegger’s discourse on falling, showing that the subject’s discourse and relationship to the truth of Being is at the core of his constitution and neurosis.

Background Checks for Firearms Sales and Loans: Law, History, and Policy

This article examines past and present systems requiring that a person receive permission before buying or borrowing a firearm. The article covers laws from the eighteenth century to the present. Such laws have traditionally been rare in the United States. The major exceptions are antebellum laws of the slaves states, and of those same states immediately after the Civil War, which forbade gun ownership by people of color, unless the individual had been granted government permission. Today “universal background checks” are based on a system created by former New York City Mayor Michael Bloomberg and his “Everytown” lobby. Such laws have been enacted in several states, and also proposed as federal legislation. Besides covering the private sale of firearms, they also cover most loans of firearms and the return of loaned firearms. By requiring that almost all loans and returns may only be processed by a gun store, these laws dangerously constrict responsible firearms activities, such as safety training and safe storage. Massachusetts, Connecticut, and California are among the jurisdictions which have enacted less restrictive, more effective legislation which create controls on private firearms sales, without inflicting so much harm on firearms safety.

Surréalisme Sous-L’Eau : science and surrealism in the early films and writings of Jean Painlevé

A French biologist who moved in Surrealist circles, Jean Painlevé began making films about underwater creatures in 1927, and by 1982 had created over two hundred films on a broad range of natural, scientific, and political subjects. His underwater films remain the most ethereal and poetic works in his oeuvre, and he specifically used cinema to capture the mystery and wonder of nature.
