Inga Clendinnen has been described as an anthropologist, a public intellectual, a writer, a poet in prose, a Mesoamericanist, and a student of the Holocaust and Australia. She was all this, but she insisted that she was always and mainly a historian. A cultural historian without portfolio, I would say. This essay aims to introduce her written work as a whole, its main purposes, themes, and approach.  相似文献

ABSTRACT

Refugee policy involves a two-level game. For Australia since approximately 1998, the politics of refugees has been toxically affected by domestic politics. This has had potentially negative effects on Australia’s reputation and soft power. This article provides an overview of the issue, explores the ways in which considerations of domestic politics have come increasingly to shape Australia’s policy and concludes with a discussion of the consequences of Australia’s treatment of refugees for its diplomacy and soft power.  相似文献

The abundance, accessibility and value of limpets as a source of food and bait for coastal peoples have resulted in their high frequency in shell middens worldwide. The limpet Patella vulgata is found in middens from the Mediterranean to Norway, and morphometric and sclerochronological analyses of its shell can provide insight into harvesting patterns and paleoenvironmental variables valuable in reconstructing climate. Previous work with P. vulgata has relied on lines on the exterior of the shell, or on lines exiting on the shell surface in shell cross-section, as annual or sub-annual markers. Shell damage may compromise these lines and limit the use of some shells, but growth lines are also found in the better-preserved shell apex. We investigated whether the growth lines in the apex of P. vulgata from two locations in Northern Europe are annual using calcein-marking and recapture. Investigations were performed at one site in the Shetland Islands (UK) and at one site at the northern limit of P. vulgata's range in Northern Norway. We also used laser ablation to measure the concentration of minerals in the shells of two individuals from Shetland to determine if patterns of minerals suggested as bioproxies for temperature and productivity varied annually. All individuals deposited one growth line in the apex during their year in the field, and the lowest ratios of Sr/Ca and Ba/Ca and to a lesser extent Mg/Ca were coincident with annual lines on the shells from Shetland. Growth at both sites was modelled using the von Bertalanffy growth function, and apex growth was nearly five times faster in Shetland than in Norway, probably a result of differences in temperature between the two locations.  相似文献

This is a nontraditional PSJ article. It is intended as an advocacy essay on one way to study organized interests and their public policy role. It's written in a light-hearted fashion, calling for more professional involvement in the actual politics of public policy, going beyond Fenno's famous “soaking and poking.” There are three purposes here. One is emphasis on the usefulness of intense policy domain studies. The second is arguing for close and ongoing academic relationships with policy players. The third is arguing that those relationships provide wonderful opportunities to gather large and reliable data sets that are unavailable otherwise.  相似文献

This paper explores the encoding and decoding of power relations in Belfast. The paper argues that during and since the Northern Ireland Peace Process came to fruition, symbols of past domination in the built environment have become politically and psychologically sensitive. A new discourse for the built environment of Belfast is called for.  相似文献
