The effort to create a colony of African Americans on the west coast of Africa was one of the most celebrated and influential movements in the United States during the first half of the 19th century. While historians have often viewed African colonization through the lens of domestic anti-slavery politics, colonization grew from an imperial impulse which promised to transform the identities of black colonists and indigenous Africans by helping them to build a democratic nation from the foundation of a settler colony. By proposing that persons of African descent could eventually become self-governing subjects, the liberal framework behind colonization offered the possibility of black citizenship rights, but only within racially homogenous nation-states, which some proponents of colonization imagined might lead to a “United States of Africa.” This dissertation examines how the notion of expanding democratic ideals through the export of racial nationhood was crucial to the appeal of colonization. It reveals how colonization surfaced in several crucial debates about race, citizenship, and empire in the antebellum United States by examining discussions about African Americans’ revolutionary claims to political rights, the bounds of US territorial expansion, the removal of native populations in North America, and the racialization of national citizenship, both at home and abroad. By examining African colonization from these perspectives, this dissertation argues that the United States’ efforts to construct a liberal democracy defined by white racial identity were directly connected to the nation’s emerging identity as a defender and exporter of political liberty throughout the world.

We construct a family of examples of increasing homeomorphisms of the real line whose local quasi-symmetric distortion blows up almost everywhere, which nevertheless can be realized as the boundary values of David homeomorphisms of the upper half-plane. The construction of such David extensions uses Carleson boxes.

Watkins proposes a neo-Popperian solution to the pragmatic problem of induction. He asserts that evidence can be used non-inductively to prefer the principle that corroboration is more successful over all human history than that, say, counter-corroboration is more successful either over this same period or in the future. Watkins's argument for rejecting the first counter-corroborationist alternative is beside the point. However, as whatever is the best strategy over all human history is irrelevant to the pragmatic problem of induction since we are not required to act in the past, and his argument for rejecting the second presupposes induction.

Philosophers have long been fascinated by the connection between cause and effect: are 'causes' things we can experience, or are they concepts provided by our minds? The study of causation goes back to Aristotle, but resurged with David Hume and Immanuel Kant, and is now one of the most important topics in metaphysics. Most of the recent work done in this area has attempted to place causation in a deterministic, scientific, worldview. But what about the unpredictable and chancey world we actually live in: can one theory of causation cover all instances of cause and effect?Cause and Chance: Causation in an Indeterministic Worldis a collection of specially written papers by world-class metaphysicians. Its focus is the problem facing the 'reductionist' approach to causation: the attempt to cover all types of causation, deterministic and indeterministic, with one basic theory.

To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a higher density of segmental duplications, enrichment of repetitive elements, and species-specific variations in genes associated with lactation and immune responsiveness. Genes involved in metabolism are generally highly conserved, although five metabolic genes are deleted or extensively diverged from their human orthologs. The cattle genome sequence thus provides a resource for understanding mammalian evolution and accelerating livestock genetic improvement for milk and meat production.

Este artigo busca uma compreensão da trajetória do antropólogo britânico, radicado nos EUA, David Maybury-Lewis. Aborda aspectos de sua formação intelectual, que envolveram uma longa pesquisa entre os Xavante e um estudo comparativo sobre os povos de língua jê e bororo do Brasil Central. Maybury-Lewis é um nome central para o desenvolvimento de um "americanismo tropical". Entre suas contribuições etnográficas e teóricas, pode-se citar a elaboração de um modelo analítico jê e bororo, a renovação dos estudos de parentesco e a reflexão sobre a relação entre povos indígenas e o Estado. Um tema parece, com efeito, permear a sua obra: o das organizações dualistas. Não por menos, esse foi o motivo de um longo debate com a obra de Lévi-Strauss, que será aqui destacado.
