A longitudinal approach to migration behavior makes it possible to identify a sufficient condition for positive associations between rates of in-migration and rates of out-migration in the same regions. The longitudinal approach centers on the intervals of time that individuals spend in a region, and these intervals can be analyzed in terms of probability distributions or the equivalent hazard functions or survivor functions. Differences in the distributions of these intervals between subpopulations whose residence in a region begins with in-migration and subpopulations whose residence begins with other events are sufficient for temporal variations in rates of in-migration to produce variations in out-migration rates in subsequent periods of time. Tests for such differences are performed using data from the National Longitudinal Survey of Youth.  相似文献

Current western aid and development policy aims to promote ‘good governance’ in the third world. Few would deny that competent, open and fair administration is both a worthy aim and a self-evident requirement of development. However, the current orthodoxy clearly illustrates the technicist fallacy, which is implicit in the following quotation from Pope, that the effective administration or ‘management’ of development is essentially a technical or practical matter. This article argues that development is fundamentally a political matter and that it is illusory to conceive of good governance as independent of the forms of politics and type of state which alone can generate, sustain and protect it. For Forms of Government, let fools contest; Whate'er is best administered, is best. (Pope, 1734: Bk 3, lines 303-4).  相似文献

This paper develops a nested family of market interaction models for the general case of spatial or aspatial goods. Market structure effects are identified in the form of intraregional and extraregional competition. The competing destinations and competing central place models are shown to be special cases of the general modeling framework. An empirical example, using survey data collected from Chicago-area Management and Public Relations (SIC 874) firms, illustrates how the family of models may be used to identify market structure.  相似文献

This article draws on a piece of wide-scale mixed-methods research (n = 429) that examines how women who write and read male/male erotica feel their involvement with the genre has affected their views on gender and sexuality and their political engagement with gay rights issues. Previous work has looked at how online slashfic communities might provide a safe space for exploring gender performance and sexuality, while other researchers have observed a tension between those who identify as queer themselves and those who only ‘play at queerness’ exclusively within the online environment. However, much of this work has examined the theoretical positioning of such forums as transgressive and/or political. Far fewer pieces have attempted to engage with the women who frequent such sites to ask them about whether their involvement in these online spaces has affected their attitudes and behaviours. This study looks not only at the ways in which online m/m fandoms can act as a safe space for women to explore their sexualities and gender identities, but whether and how these insights connect to women’s real-world lives. Data presented here shows a strong consensus among participants that involvement with explicit slash communities has had a positive effect on their lives, as well as contributing to beneficial changes in their knowledge, attitudes, and practices with regards to LGBTQ+ issues. Overall, slash is seen as a medium which can create better allies, encourage cross-identification, and bring about positive personal changes. To this extent, I argue that explicit online slash sites can act as heterotopias.  相似文献

Guatemalan author Rodrigo Rey Rosa’s first novella, Cárcel de árboles (1991), tells the story of a secret politico-medical experiment conducted on prisoners who have been condemned to death by the State. The experiment takes place in a prison camp located in the tropical forest. In this article, I examine the portrayal of power and embodiment in Rey Rosa’s novella, placing the text in dialogue with thanatopolitical theory and outlining the ways it evokes the historical context of violence and economic transition in Guatemala. I commence by discussing the forms of power at work in the novella’s prison camp, before examining the significance of medical science to Rey Rosa’s depiction of embodiment. I then explore the complex aesthetic and ethical questions embedded in the relationship between language, textuality and the body in the novella. Finally, I discuss the post-human dimensions of the text that emerge in the relationship between the human bodies of the prisoners and the non-human terrain. Over the course of this analysis, I contend that Rey Rosa marshals the body to invoke the ways in which the category of the ‘human’ is formed, deconstructed and reconfigured in the face of the destructive power that operates in the modern techno-scientific epoch.  相似文献

Conversations around, and conceptions of, citizenship have changed over time. Assumed initially as a mark of membership, of belonging to a political community (Marshall 1950), the essence of what it means to be a citizen and what the contractual ties of citizenship are have evolved over time. This evolution has been encouraged by processes of migration and increasing mobility. More recently, our ability to traverse geographical and political boundaries has meant that notions of borders and boundaries, of who belongs where and why, have also been subject to dramatic changes. This article investigates the impact of such mobility on the individual lived experience of migrant women who, as a group, have been traditionally excluded from more formal political arenas, and asks questions of what citizenship means for them. Though I do not contest the very political fact of citizenship as status, this article challenges the way in which the nature of this status is assumed or implied for all. This article therefore argues that citizenship itself is a much more fluid concept, incorporating the emotional and lived experience of individuals and that it is in these emotional accounts through which citizenship, and its extended rights and political capabilities, must be understood through a sense of everyday, grounded and personal politics.  相似文献
