Abstract. The 1990s debate on minority rights clearly indicates that minority issues are among the most controversial subjects of international relations. Questions concerning national minorities gained new prominence in international relations, especially in East Central Europe, following the end of the Cold War. Between 1990 and 1995 the formulation of international standards regulating state conduct towards national minorities was a priority for European organisations. This standard setting episode raises several important questions. Why did national minorities reappear on the international agenda after 1989? How were they responded to? Why did state sovereignty continue to take precedence over minority rights?  相似文献

Using Canada’s National Film Board (NFB) as a case study, this paper highlights a paradigm shift in media policy away from supporting diverse content in favor of new digital formats. Historically the NFB has supported Aboriginal media production as a hallmark of the institution’s founding commitment to representing Canada’s people and culture. However, in recent years the institution has shifted its focus to digital technologies and interactive productions. This research is rooted in both a quantitative and qualitative examination of NFB official reports and related press coverage. The examination demonstrates a decrease in emphasis on Aboriginal production and an increase in attention to new technologies.  相似文献

Over the past four decades several workers have argued that the orientations of striations on the labial surfaces of the front teeth of Middle and Late Pleistocene fossils attributed to Neanderthals and antecedent archaic hominids can tell us something about handedness. These researchers have suggested that such scratches result from stone tools scraping across the incisors during ‘stuff‐and‐cut’ behaviours, and that they reflect directions of hand movements and handedness. In this study, we examine comparable wear features on the incisors of anatomically modern humans to determine whether striation angle may reflect handedness. The teeth from 66 individuals representing four groups with known differences in subsistence practices (Aleut, Arikara, Illinois Bluff, and Puye) were examined. Photomicrographs were made of the maxillary central incisor labial surfaces of all individuals at 56× magnification. These photomicrographs were scanned to image files, and orientations of all visible wear striations were measured using a semi‐automated image analysis procedure. Approximately three‐quarters of all labial surfaces showed a preferred striation orientation. Of those, most had preferred apico‐cervical or vertical striation orientations, independent of cultural affiliation. Few showed the tendency toward diagonally‐oriented scratches expected if handedness is related to scratch orientation. We found no evidence for ‘stuff‐and‐cut’ striations, despite the fact that at least one of the groups studied—the Aleut—are documented to have used this behaviour. In sum, there is evidently no relationship between striation orientation and handedness in the groups studied. It is, therefore, unlikely that labial scratch orientation in Middle and Late Pleistocene hominids reflects handedness if they used their front teeth in a manner comparable to that of any of the anatomically modern groups considered here.

Stable carbon (δ13C) and nitrogen (δ15N) isotope ratios are commonly used to reconstruct palaeodiets and palaeoenvironments. The method is based on our knowledge of isotopic patterns in plants, which are subject to taxonomic and environmental variability. While previous researchers have addressed isotopic variability amongst plants, no studies have looked extensively at a broad suite of taxa over multiple temporal scales from within the savanna biome so as to provide baseline data for palaeodietary and palaeoenvironmental studies. Here we document variations in the isotopic compositions of plants collected over two years from the Kruger National Park, South Africa, with respect to species and anatomical differences, and the influences of geological substrate and spatio-temporal shifts in climate. Results show that environmentally-induced carbon isotopic variations in plants within this region are generally smaller than 2‰, which is lower than what has been previously reported for plants compared across multiple habitat-types. These data suggest that δ13C differences of 2‰ or more (or 1‰ if the diet is predominantly C4) between animals from a given area reliably indicate real dietary differences. Plant δ15N values vary greatly between different microhabitats (by up to 4‰), responding to a range of environmental influences that may, in turn, significantly influence variation in animal δ15N values.  相似文献

Risk perceptions are important to the policy process because they inform individuals’ preferences for government management of hazards that affect personal safety, public health, or ecological conditions. Studies of risk in the policy process have often focused on explicating the determinants of risk perceptions for highly salient, high consequence hazards (e.g., nuclear energy). We argue that it is useful to also study more routinely experienced hazards; doing so shows the relevance of risk perceptions in individuals’ daily lives. Our investigation focuses on the impact perceived risk has on citizens’ preferences over hazard management policies (as distinct from identifying risk perception determinants per se). We use a recursive structural equation model to analyze public opinion data measuring attitudes in three distinct issue domains: air pollution, crime, and hazardous waste storage and disposal. We find that citizens utilize perceived risk rationally: greater perceived risk generally produces support for more proactive government to manage potential hazards. This perceived risk–policy response relationship generally holds even though the policy options respondents were asked to consider entailed nontrivial costs to the public. The exception seems to be when individuals know less about the substantive issue domain.  相似文献

This article considers why and how locality influenced feminists' perceptions of colonised women. It does so through an analysis of how militants and novelists linked with the Union Française pour le Suffrage des Femmes (French Union for Women's Suffrage, UFSF) perceived the Arab and Berber women of colonial North Africa. The organisation had branches in North Africa, and thus feminists in Algeria, Morocco and Tunisia are compared to those in France. Where these women lived shaped their understanding of French women's roles in the colonies, along with their opinions regarding the rights to which colonised women could lay claim. Tensions among UFSF members are traced here through the literary figure Elissa Rhaïs, articles in the feminist newspaper  La Française  and correspondence among UFSF members. These sources indicate that while all these French women positioned themselves as mediators of colonialism and women's rights, their precise interpretations of that mediation were consistently influenced by local concerns.  相似文献
