Differences in both regional skill prices and skill mix can explain interregional variations in wage distributions. We control for interregional differences in skill mix that permit us to compute key parameters of regional wage distributions including regional returns to skills. In addition to setting forth the methods in detail, we also present estimates for 48 U.S. states and 10 Canadian provinces. For both males and females, we find that regional mean wages (with controls for skills mix) in the U.S. and Canada are similar, but that the returns to skills are systematically higher in the U.S. 相似文献

This article explores intersections between academic work and emotional work at a feminist geography reading weekend held by the Women and Geography Study Group of the Royal Geographical Society-Institute of British Geographers in the UK in 2006. It points to the importance of the fleeting, often unreported, spaces of feminist geographical praxis and of inserting these in our disciplinary histories. Using a performative textual strategy it offers a poly-vocal reflection on the complex, challenging and productive experiences of this kind of academic workspace. In so doing it contributes to feminist engagements with the practices of neo-liberal academia, to debates about the emotional geographies of feminist geographical work, and to discussions of the value of activities outside the norms of academia in providing potentially supportive and creative spaces for geographical praxis. 相似文献

The first ever simulations of global patterns of early Homo morphology are presented here. These simulations are a good match to the known patterns in the fossil record. An enhanced version of the Stepping Out model is presented which simulated global patterns of hominin morphology including genetic drift and the homogenising effects of inter-group exchange. Stepping Out is then used to examine the importance of environmental factors on hominin morphology. The most significant feature of the simulations is an emergent division between the African and Asian populations. The effect of biogeographical factors on this division and other patterning is considered. Throughout, modelling results are interpreted in the context of fossil and archaeological records in order to enhance our understanding of population histories of hominin groups. 相似文献

Credible interpretation of pollen recovered from archaeological sites hinges upon understanding how pollen becomes deposited by both the environment and human behavior. The environmental role has been studied to some extent, but how the activities of people have formed the pollen assemblages at archaeological sites is usually just assumed rather than considered explicitly. Moreover, the complexity involved in the interaction between human behavior and pollen ecology is seldom considered. An archaeological case study of grinding tool pollen washes highlights the ambiguities of standard practice because the results confound common assumptions about pollen washes. A series of experimental seed and grinding tool washes designed to test the relationships between the processing of seeds and the deposition of pollen help explain why, for most situations, artifact pollen washes do not provide direct or even faithful records of plant processing. These results highlight the need for further experimental research with pollen so that we are warranted in making behavioral inferences from palynology. This conclusion is easily extended to other microbotanical data classes that archaeologists regularly employ. 相似文献

Escaping one heritage of British colonialism for another, Irish immigrants to Canada in the nineteenth and early twentieth century helped to shape the image of Canada and Canadian nationalism. In this paper, I compare the diversity of Irish immigrant experiences in Canadas urban and wilderness landscapes. The Irish immigrant experience in major urban centers is well documented. Community neighborhoods, Church activities and domestic and manual labor constitute just part of the stories of urban Irish Canadians in cities such as Toronto. The popular conception of the Irish as strictly city people is strengthened by the lack of discussion of the Irish immigrant role in taming (and ideologically shaping) the wilderness of Western Canada. It is argued that this has to do with the colonial image of the Irish from which British imperialist Canada sought to distinguish itself. 相似文献

Brain death and the historical understanding of bioethics 总被引:1,自引:0,他引:1
Belkin GS 《Journal of the history of medicine and allied sciences》2003,58(3):325-361
In a 1968 Report, the Ad Hoc Committee of the Harvard Medical School to Examine the Definition of Brain Death promulgated influential criteria for the idea and practice known as "brain death." Before and since the Committee met, brain death has been a focal point of visions and nightmares of medical progress, purpose, and moral authority. Critics of the Committee felt it was deaf to apparently central moral considerations and focused on the self-serving purpose of expanding transplantation. Historical characterizations of the uses and meanings of brain death and the work of the Committee have tended to echo these themes, which means also generally repeating a widely held bioethical self-understanding of how the field appeared-that is, as a necessary antidote of moral expertise. This paper looks at the Committee and finds that historical depictions of it have been skewed by such a bioethical agenda. Entertaining different possibilities as to the motives and historical circumstances behind the Report it famously produced may point to not only different histories of the Committee, but also different perspectives on the historical legacy and role of bioethics as a discourse for addressing anxieties about medicine. 相似文献
