Because global labor markets affect the self-assignment of academics, they also affect structural changes in migration movements. To understand the migration patterns of highly qualified academic scholars, research has focused on their mobility, including their return migration. Thus far, studies have examined migrants from Latin America to the United States, but the impacts of cultural or societal contexts on migration have not been investigated.

Based on an empirical study of Russian academics who have migrated to Germany, we propose theory-based answers to the following questions: Is trust a relevant motivation for homeward-bound academic migrants to return to their native countries, and who or what is the object of this trust? Why do these migrants, in contrast to the vast majority of interviewees, self-identify with their society of origin? Does transaction cost theory explain these academics' motives for migration? Is their temporary stay beneficial to the host society?  相似文献

Malaysia's electoral authoritarian system is increasingly coming under pressure. Indicators of this are the metamorphosis of opposition forces since 1998 and, in particular, the results of the 2008 parliamentary elections. From 1957 until 1998 political party opposition was fragmented. An initial transformation of political party opposition began at the height of the Asian financial crisis, after a major conflict within the ruling United Malays National Organization in 1998. However, the regime was able to weaken the opposition, resulting in its poor performance in the 2004 elections. Afterwards, in a second transformation that has continued until the present time, an oppositional People's Alliance (Pakatan Rakyat) has emerged that now has a serious chance of taking over the federal government. This article argues that the increase in the strength and cohesion of political party opposition since 1998 has been caused mainly by five combined factors: the emergence of pro-democratic segments within a multi-ethnic and multi-religious middle class; the intensified interaction of political parties and civil society forces; the impact of new media; the eroded legitimacy of the United Malays National Organization and other parties of the ruling coalition; and the internal reforms within the Islamist Pan-Malaysian Islamic Party (Parti Islam SeMalaysia). Consequently it has become conceivable that the country will incrementally democratize in a protracted transition. Although the 1999 and 2008 elections were not foundational, they have been transitional. They may not have inaugurated a new democratic regime, but they have marked important phases in the struggle for democracy in Malaysia.  相似文献

The main purpose of this article is to elaborate some conceptual tools for clearer analysis of social reality, power relations and their visual representations. One of these instruments through which power relations are established in society is photography. The paper focuses on different strategies by which, in photography, the “people” are constructed as a homogeneous whole of specific historical self-reflection of culture. The first part of the paper discusses the relationship between the theory of hegemony as elaborated by Ernesto Laclau and the semiotics of culture of Yuri Lotman. The ground for believing this incorporation of the two thinkers to be successful is the very apparent theoretical congeniality between them. They both belong to the Saussurean ontological terrain. The second part of the paper tries to develop a bridge between the given theoretical framework, especially Laclau's concept of empty signifier and Barthes's concepts of studium/punctum, and “iconic photograph” from visual rhetoric. I will distinguish four hegemonical strategies of signification: visual naming, dominant text, code text, and dominant language. The analysed material is taken from Stalin-era soviet Estonia's newspaper and magazine photographs.  相似文献

Previous research is unclear about which citizens support the use of referendums and how a referendum campaign can affect support for direct democracy. This study investigates, first, the factors that determine support for referendums and, second, the role of the campaign in changing support. This is done in the context of the 2005 Dutch EU Constitution referendum. A media content analysis of national media (N = 6,370) is combined with panel survey data (N = 1,008). The results suggest that those who felt more politically disaffected were more supportive of referendums. Furthermore, higher levels of exposure to tabloid style campaign news led to increased approval of referendums. In a second step, the mechanism behind this effect was tested using an experiment (N = 580). When exposed to negative tabloid style news about a referendum proposal, opponents perceive the assumed consequences as more of a threat. This threat perception increased their support for a referendum on the issue at stake as a means to prevent the proposal. The article concludes with a discussion about the conditions under which a dynamic like this is likely to unfold and when alternative explanations for referendum support apply.  相似文献

The importance of forensic age estimation in living subjects has grown over the last few years. In dental age estimation, tooth eruption is a parameter of developmental morphology that can be analyzed by either clinical examination or by evaluation of dental X-rays. In the present study, we determined the stage of wisdom tooth eruption in 410 male and 106 female Black South African subjects of known age (12-26 years) based on radiological evidence from 516 conventional orthopantomograms. Four eruption stages were determined (no emergence, alveolar emergence, gingival emergence, complete emergence). Statistical scores were determined for the individual stages separately for both sexes. The data presented here can be utilized for forensic estimation of the minimum and most probable ages of investigated persons.  相似文献

A sensitive and specific method for the determination of gamma-hydroxybutyric acid (GHB) in urine and serum is described. Prior to quantification by LC/MS in a Pauli-type ion trap, the molecule is converted by a fast and simple one-step procedure into its n-butyl ester derivative. Hexa-deutero GHB has been used as internal standard.  相似文献

An unknown male body was found near an expressway in Germany. As different criminalistic and forensic methods (e.g. tooth status, fingerprint or DNA-analysis) could not help to identify the person, multielement stable isotope investigations were applied. The combined analysis of stable isotope ratios of light (H, C, N) and heavy elements (Pb, Sr) on the man's body tissues supported to assign him to Romania. The case report demonstrates an application of multielement-isotope analysis in the forensic fields and its potential.  相似文献

Risk is a projection of a specific temporality performed by the observer. However, this projection is doomed to impossibility because of the prohibiting problems of time, causality, subjectivity and relativity of risk. The observer is left only with a castrated projection that defies the role of science as a pedestal for the projection and institutes negation as its driving force. This projection is materialised within the Law in the form of the Precautionary Principle. Risk evokes undesired dualisms, especially the one between Idealism and Operationalism. The essay attempts to bring the two together by extrapolating the hard appearance of the legal system as seen through Luhmann’s autopoiesis and the need for critical openness of a contextualised environmental law. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

The vertical integration of Fisher Body by General Motors has been a leading example in both the transaction-cost theory and the property-rights theory of the firm. The present paper makes the following contributions. First, we show how a simple extension of the property-rights theory of the firm (which allows for contractible trade) is able to rationalize the observed ownership arrangements, supply contracts, and investment behavior both before and after integration. Second, the model lends support to Klein’s (2000) view that an increase in demand for closed automobile bodies was pivotal for vertical integration. JEL Classification L22 · L24 · L14 · K12  相似文献
