The paper gives a review of the advantages of genetic information potentially available from surviving molecules (especially proteins) in bone. Survival of such information depends on degradative processes during burial. Conventional protein chemical and immunochemical investigations on various organic components remaining in buried archaeological bone are described. The results provide information on the chemistry of collagen degradation, and indicate that polymorphic macromolecules survive at too low a concentration to be easily detectable. 相似文献

The historiography of the Sabbath reflects closely the concerns of its Sabbatarian subjects: the rise or fall in public piety and the effectiveness, or lack thereof, of evangelical moral reform and social control. In this article we step away from the question of how religious or secular goldfields society was, and instead, observe how Sunday functioned on the goldfields. In doing so we eschew a dominant narrative of religious history — secularisation — and deploy a postsecular analysis. Such an analysis reveals a remarkable degree of social cohesion: a diverse, but common, practice of rest on the Sabbath. It was only because of the universal honouring of the goldfields’ Sabbath that government troops were able to so quickly and decisively end the Eureka Stockade on Sunday, 3 December 1854. 相似文献

This essay provides a critical review of the field of immigration policy studies from the perspective of measurement and modeling. It serves to contextualize and broaden the views presented in the special issue. As such, we combine insights from American and comparative politics, pinpoint key limitations and challenges in the field, and identify areas of strength within each subfield which could inform theory and measurement development for the other. Ultimately, the concerns about conceptualization, definition, and measurement that we identify and discuss herein, do not apply only to immigration policy studies but to policy studies writ large. 相似文献

Public policy and economic practice, quintessential expressions of institutional cognition, create an opportunity structure constituting a tunable, highly patterned,‘non‐white noise’ in a generalized epidemiological stochastic resonance that can efficiently amplify unhealthy living and working conditions, particularly within highly concentrated, marginalized urban populations, to evoke infectious disease outbreaks. This is especially true for the infections carried by socially generated ‘risk behaviours’ which are usually adaptations to histories of resource deprivation or marginalization. A number of local epidemics originating in such ecological keystone communities may subsequently undergo a policy and structure‐driven phase transition to become a coherent pandemic, a spreading plague which can entrain more affluent populations into the disease ecology of marginalization. We use this approach to contrast the ecological resilience of apartheid and egalitarian social systems, and apply these perspectives to the forthcoming social and geographical diffusion of multiple drug resistant (MDR) HIV from present AIDS epicentres to the rest of the United States. 相似文献

Participatory policy analysis (PPA) has been recommended as a means for better informing the policy process and reinvigorating citizen participation in government decisionmaking. This study analyzes the Vermont Forest Resources Advisory Council (FRAC), a stakeholder form of PPA, to assess trust and understanding, which PPA proponents suggest is important for democratic governance. Findings indicate that process design and the roles of science and social values in decisionmaking affected trust and understanding among participants and in the FRAC process. This case highlights challenges in making PPA operational and in addressing positivist and postpositivist perspectives within PPA. 相似文献
