Despite similar permanent status immigration categories (Economic, Family, and Refugee), the experiences of skilled immigrants in Canada and the United States are quite different. The point system used to select applicants for the Economic Class in Canada makes skilled immigrants vulnerable to a number of perils after the migrant lands. Foreign credentials and work experience are discounted by Canadian employers, who also impose a discriminatory income penalty on minorities. While previous cohorts of Economic Class migrants may have been warned of these perils via reliable migrant networks, new Canadian research suggests that recent cohorts have no such safety net. This article examines the economic integration experiences of Economic Class migrants in the United States in light of the Canadian experiences. The vulnerabilities reported in Canada do not appear to be transferable to the United States, because immigration policy in the US stresses pre-landing employment commitments via employer sponsorship. Accordingly, prospective Economic Class migrants to the United States do not migrate without first knowing how their credentials and “minority status” will affect employment opportunities. However, for the 85,000 skilled workers admitted to the United States on H-1B temporary visas each year, the perils noted in the Canadian experience are relevant, as are a number of additional concerns.  相似文献

The Briand Memorandum in 1930 was the most important effort to create stronger European political unity in the interwar period. The responses by the governments of Sweden, Finland and Estonia have not been studied before. It is convenient to study these replies together and focus on possible cooperation between neighbouring countries. Whilst France was using the Memorandum to europeanize her relations with Germany, Sweden, Finland and Estonia also adopted the Memorandum to their foreign policy. As a result a common policy towards the Memorandum could not be found, despite the fact that the three countries agreed on multiple issues.  相似文献

The skeletal elements of mountain gazelle (Gazella gazella) have proven difficult to sex with statistical confidence due to wide overlap in the body size of the two sexes. We studied a sample of 53 modern mountain gazelle skeletons to determine which character traits and metric measurements best predict sex. The success of the character traits was determined using blind tests while the metrics were examined using discriminant function analysis. The most useful elements include the previously identified horn core, pubis and atlas, but also some new bone portions that preserve well in the archaeological record (e.g., distal tibia, distal metacarpal and metatarsal, and second phalanx). Surprisingly, two elements commonly used in sexing analyses (distal humerus and astragalus) were not among the most effective elements. Although cutting points and discriminant functions for sexing gazelle bone portions are presented here, they do not account for potential body size change and thus are not suited for direct application to archaeological assemblages. Instead, we provide guidelines for application to archaeological gazelle assemblages, most importantly a regression analysis that considers the sex ratios obtained from multiple measurements to predict the sex ratio of archaeological gazelle populations.  相似文献

In Australia, the Commonwealth and State governments are increasingly devolving natural resource management (NRM) responsibilities to regional bodies. This move has led to the development of regional NRM plans. Native vegetation and biodiversity conservation, along with soil, pasture and water resources, are key components of the regional NRM plans in Queensland's extensive rangelands. This paper outlines and applies a set of criteria for evaluating the native vegetation and biodiversity content of accredited regional NRM plans for Queensland's rangelands. The evaluation showed considerable variation in the comprehensiveness of the information and knowledge base and management action targets among plans, including the poor articulation of impacts of excessive grazing pressure on biodiversity. The NRM plans lacked effective integration of natural resource, native vegetation and biodiversity conservation targets and actions. Several regions had too many biodiversity targets, many of which were poorly integrated. This is symptomatic of a limited understanding of rangelands as ecological systems and the lack of an integrated planning framework. We conclude regional NRM planning is not a ‘silver bullet’ for biodiversity conservation in the rangelands, but rather, it is the beginning of a long road to address complex, multi‐scale problems at a regional level.  相似文献

Race relations organisations in Britain hailed Sikhs as models of peaceful integration during volatile political debates about the immigration of Commonwealth peoples during the 1960s and early 1970s. But Sikh campaigns to protect the sanctity of turban-wearing challenged this symbiotic relationship. This article explores how motorcycle helmet laws provoked a campaign to protect the Sikh turban and allowed diasporic Sikhs to articulate their concerns about British integration and race relations expertise during the mid-1970s. Sikh campaigners linked restrictions on turban-wearing to concerns about race relations legislation, equal employment policy, and their rights as British residents. In assessing the fluctuating relationship between Sikh activists and race relations authorities, it reveals the fractures in pluralist integrationist ideologies that continued to prioritise British cultural authority. The evidence here also demonstrates that this moment provided British Sikh communities with an unprecedented opportunity for national solidarity and diasporic community-building.  相似文献

Abstract

This article reconstructs concepts of ‘European solidarity’ in Helmut Schmidt’s political thought. Tracing Schmidt’s beliefs from the late 1940s to the period of his chancellorship and beyond, it shows how his concepts of European solidarity were shaped by the lessons he drew from the political and economic catastrophes of the 1920s and 1930s. The article reveals how Schmidt developed a largely functionalist understanding of ‘European solidarity’ that was grounded in both his generational experience and the piecemeal logic of European integration he derived from Robert Schuman and Jean Monnet. Schmidt believed that ‘European solidarity’ was not a given, but that it had to be consciously constructed through mutually beneficial intra-European cooperation. He was guided by two central convictions: that the interdependence of European economies made their cooperation both necessary and desirable; and that Germany’s unique historical burden and geostrategic location meant that its foreign policy always had to be embedded in a wider European framework. As West German Chancellor from 1974 to 1982, Schmidt then sought to translate these convictions into practice, trying to avoid a relapse into 1930s protectionism whilst at the same time hoping to avoid perceptions of German dominance in economic matters. Yet, he remained highly sceptical of any attempts to transfigure West European integration into a greater ‘European identity’, believing that the Cold War context made any such attempts futile since true European solidarity could only be practised on a pan-European scale. Putting these views in a broader context, the article concludes that Schmidt’s thoughts offer valuable insights into the relationship between constructions of ‘European solidarity’ and notions of ‘crises’, and suggests that the analysis of his pragmatic approach adds to new, less teleological narratives of European integration that are now emerging in the historiography.  相似文献
