Pseudochirops winteri n. sp. is described from the Pliocene Bluff Downs Local Fauna on the basis of a left dentary fragment with M2. It is considered to be most similar to P. archeri although its phylogenetic position must remain tentative until further material is found. The presence of this presumably rainforest-dwelling possum, the first from this fauna, may indicate a limited closed forest component. Given the paucity of additional rainforest taxa recovered from this site despite extensive screen washing, however, such a component must have been restricted to gullies or riparian fringes.  相似文献

Political science as a distinct discipline only emerged in the Australian academy after the Second World War. By the end of the 1950s it was attracting thousands of undergraduates. Into the 1990s and beyond, political science has remained a relatively 'successful' discipline. However, it would be difficult to argue that the identity of Australian political science has been forged by disputes over the 'scientific' core of the discipline. Some Australian political scientists have claimed that this deficit is a fundamental weakness, denying the discipline both a set of common professional values and a basis for the integration of research. By contrast, this paper will argue that the issue of identity is better considered from a historically sensitive perspective rather than purely in terms of profession and methodology.  相似文献

The Southwest Michigan Historic Landscape Project was initiated in 1994 to examine how the cultural landscapes and associated material culture of the region became transformed since the pioneer settlement of the early 19th century (ca. 1830s). Thus far we have used various methods to investigate four sites in Allegan, Calhoun, and Jackson counties at varying levels of intensity. From these initial efforts we have begun to compile comparative information on the built environment. Here we present the theory and methods used in the project and discuss how class, gender, and ethnic identities are expressed in the material record of the region.  相似文献

Prior to the early 1950s, Americanist archaeologists, given their interest in chronology, routinely searched for direct historical connections between ethnographically documented cultures and archaeological cultures. In those instances where clear evolutionary connections existed between ethnographic and prehistoric cultures, the ethnic affinities of the latter could be assessed, chronologies of prehistoric cultures could be built, and ethnographic descendant cultures could be used as analogs of prehistoric ancestral cultures. The latter became known as specific historical analogy, and it stands in contrast to general comparative analogy, in which no detectable evolutionary connection exists between archaeological subjects and ethnographic sources. The theory underpinning the use of specific historical analogs is Darwinian evolutionism, or descent with modification; thus similarities between ethnographic sources and archaeological subjects are homologous. By midcentury, with the problem of chronology behind them, archaeologists began to address anthropological concerns. Darwinian evolutionism was replaced by the theory of orthogenesis as an explanation of culture change, and concomitantly specific historical analogy was replaced by general comparative analogy, in which similarities between ethnographic sources and archaeological subjects are the result of convergence. For over a century anthropologists and archaeologists have mixed elements of the two theories.  相似文献
