5he purpose of this study was to determine whether or not suspected variables affected a surgery clerk's chances of being awarded an honor rating. Findings indicated a significant relationship between a student receiving an honor rating and his or her preceptor's predetermined level of student advocacy, the number of completed patient interview and physical examination write-ups, and final examination scores. There was no significant relationship found between honor ratings and the preceptor's status, the sequence in which the student was discussed or the length of time spent discussing the student at the final evaluation meeting, or the number of clinical faculty present at the meeting. These results lend support to the faculty forum evaluation approach, but suggest a need for further scrutiny of some influencing variables to ensure all students are fairly considered and honor ratings judiciously awarded. 相似文献

"Although the flow of human beings between countries and continents has marked the behaviours of populations for centuries, present international migration is clearly characterized by a number of new factors which make it distinct from international movements of people in the past. This paper aims to identify such new factors relating to the underlying reasons for the international mobility of people, including the motivations of the individuals concerned, and attempts to examine the consequences as they are being faced by the individuals involved, the countries concerned and--in more general terms--the international community."

A historical analysis of trends in immigration to Australia and Canada from 1900 to 1983 is presented. The important role that immigration has played in the development of both countries is stressed. The steps taken to rethink immigration policies following the international economic crises of the mid-1970s are also considered, as is the increased demand for immigration by political refugees. The close relationship between political objectives and migration policies in both countries is emphasized. (summary in FRE, SPA) 相似文献

This paper analyzes similarities and dissimilarities in French and American efforts to come to grip with irregular migration. The symbolic importance of immigration reform is argued to be a key political concern in both nations, although the politics of immigration reform has assumed a more partisan flavor in France, particularly since the municipal elections of 1983. In France, the theme of control and security, associated with the notion of preventing "automatic" immigration which would endanger the cohesion of French society, was widely utilized for political ends prior to and after May 10, 1981 (the date of Francois Mitterand's investiture). The American government, on the other hand, is confronted with the unenviable task of obtaining a legislative consensus on legalization and employer sanctions through an approach seeking to harmonize and integrate the demands articulated by various groups: employers, unions, and alien and ethnic interest groups (principally Hispanic groups divided into a hierarchy along a recently arrived/established cleavage). The American situation most sharply differs from the French case in terms of the absence of a right/left political cleavage. The real effects of clandestine immigration are to be found at the local level. In France, as in the US, the ability of local actors to exert pressure raises the fear that legalization and sanctions will change little, except in terms of symbolic legitimacy. 相似文献

This paper examines 3 basic obstacles thwarting all attempts to reduce irregular migration. The 1st, rather well known and analyzed, underscores the dependency of all regulation of migratory flows on the system of economic and political relations between developed and developing countries. The 2nd obstacle resides in the persistance and growth of subsequent dependent irregular migration. This obstacle also reveals the relative autonomy of population movements compared with the employment situation in the labor market. The 3rd generally ignored obstacle is the role played by migration itself, particularly the discriminatory status of foreign workers in the labor market, in producing irregular migration. 相似文献

This paper examines changing concepts of immigration practice in the UK. Immigration control at the port of entry has extended to internal control within the UK. The burden of proof of legality of status is increasingly on the immigrant, against a background of administrative rather than criminal justice. The changing and broadening definition of illegal immigration in the UK is part of a set of policies, which are governmental responses to what is conceived of as public opinion. THE GUARDIAN suggested that the Home Office has tightened up its application of the rules as the price to the Tory Right for their silence over further changes to the immigration law, thus demonstrating the political aspects of the concept of illegality. The Home Office replied that the UK was now one of the most densely populated countries in Europe and that, in terms of services, the country simply could not support all those who would like to come there. Nor can more than a certain number of newcomers be absorbed by any host community without the risk of friction. However, the host community is now multi-ethnic, and there is a black vote. The growth of administrative justice against which there is little effective appeal, the retrospective application of the 1971 Immigration Act, the ever-widening definition of the concept of illegality along with the fact that there is no time limit under the 1971 Act for one of the most common offenses, that of over-staying, have given rise to an increasing number of campaigns in support of individuals or families. These campaigns against the deportation of "illegal" immigrants may be an indication of a change in public opinion. 相似文献

From time to time during social encounters, people look at one another in the region of the eyes, and sometimes their eyes meet to make eye-contact. According to Argyle and Dean (1965), eye-contact in dyadic encounters signals the intimacy of the interaction and is controlled largely by the competing approach and avoidance forces that motivate the pair. In the present paper, new analyses are reported of three published experiments that were designed originally to test aspects of the intimacy model and it is shown that the duration of eye-contact is no more than a chance product of how long the two subjects look individually. Looking and not eye-contact, it is argued, should be the basis for models of visual interaction, and the intimacy model is ill-founded conceptually; the role of emotion in gaze has been overstressed at the expense of the concept of information; and the most important aspect of vision is in any case not looking and eye-contact but visual access to the whole person. The more cueless the encounter—that is, the fewer the social cues from vision and all the other senses combined—the greater the psychological distance; and the greater the psychological distance, the more task-oriented and depersonalized the content of what people say and, in turn, the less spontaneous their style of speech and the less likely a debate to end in compromise.Research for this article was sponsored by the Social Science Research Council of Great Britain. 相似文献
