受访者推动抽样：研究隐藏人口的方法与实践

“隐藏人口”的特点是规模较小且成员一般不愿暴露身份，因此很难使用常规抽样方法对其进行研究。近年来出现了一种新的研究隐藏人口的方法——受访者推动抽样（RDS)方法，该方法在传统“雪球抽样”方法的基础上，结合社会网络分析的理论和方法，使研究者有可能根据样本对总体特征做出合理的推论。本文对RDS方法的理论渊源、基本思路、主要操作步骤和原理进行了简要介绍，并探讨了在实际操作过程中应注意的问题。     

The interaction between landmine clearance and land rights in Angola: A volatile outcome of non-integrated peacebuilding

The current approach to peacebuilding by the international community is to focus on the priorities thought to be important to recovery, but this occurs in a largely non-integrated way. With these different endeavors largely isolated from each other in planning, analysis, implementation, and measures for success, little is known about how they interact and whether or not the aggregate effect contributes to, or detracts from durable peace. This is especially important for priorities which in some way interact with each other on the ground among a recipient population. Two of these priorities for recovery, landmine clearance and land rights, while taking place on the same lands at the same time, and for the same people, are regarded separately as crucial to postwar recovery, and their interaction has not yet been examined. This article looks at these two priorities for Angola, and finds in their interaction a number of ways in which they detract from durable peace. This is a result of, 1) the role of areas adjacent to mine contaminated locations, 2) land grabbing, 3) the actions and role of the State, 4) the problematic interaction between different sectors involved in recovery, 5) the ongoing return of refugees and internal dislocatees and their (re)settlement, and 6) the lack of awareness of land tenure issues on the part of ‘mine action’ organizations. Subsequent to an examination of these forms of interaction this article looks at possible ways forward, focusing on, 1) the derivation of a form of ‘forced transparency’ as a deterrent to land grabbing, 2) enhancing the utility of ‘land release’ within the mine action community, 3) linkage of the different sectors concerned with mine action and land rights, and 4) the role that donors of mine action can play.     

When Adaptations Go Awry: Functional and Dysfunctional Aspects of Social Anxiety

Adaptations are psychological and behavioral mechanisms designed through evolution to serve specific purposes ultimately related to reproductive success. Although adaptations are inherently functional, in some cases their operation can nevertheless cause personal and social dysfunction. We describe a theoretical framework for understanding, predicting, and reducing the dysfunctional consequences of psychological adaptations. We discuss three general sources of dysfunction: a) the existence of adaptive tradeoffs, b) mismatches between current environments and ancestral environments, and c) individual differences. The paper applies this framework primarily to the topic of social anxiety, a psychological phenomenon marked by concerns pertaining to social rejection and embarrassment. Although social anxiety can serve useful functions, it can also involve excessive worry, negative affect, and avoidance of social situations, leading to significant distress and social impairment. We consider sources of dysfunction in social anxiety and discuss implications for policy, including recommendations for psychological, situational, and biological interventions. We also discuss broader applications of this theoretical framework to other areas of social life.     

From delusion to play

Winnicott suggested that delusions are a failed form of play. Using Winnicott's theories of the play space, this paper illustrates through clinical material how the therapist can join a delusion and convert it into an area of play. Discussion includes an analysis of the use of play in working with the transference and countertransference as well as the therapist's resistances to engaging in play.     

The periphery of care: Emergency services for homeless people in rural areas

Until recently, homelessness in rural areas has received little recognition because of overwhelming assumptions about the urban-centredness of homeless people and their needs. This paper seeks to build on recent research that has begun to uncover some of the problems and characteristics of rural homelessness, by suggesting two significant dynamics which together can shape the experience of different groups of homeless people in rural environments. First, rural places reflect particular local qualities which contextualise both the circumstances of homelessness and the provision of services in response to those circumstances. Secondly, the contemporary governance of homelessness unfolds rather unevenly in different rural areas, producing distinct local service environments with varying degrees of ‘insider’ and ‘outsider’ status in relation to joined-up responses to the needs of homeless people. These dynamics are articulated through three case studies: a remote friary in a deep rural area of southern England; a small hostel run by a vibrant non-statutory organisation in a small town in the west of England, and two advice centres in a coastal resort in the north-east of England. Through these case studies we highlight the importance of both local reactions to the homeless other, and local relations between central government funding, local authority initiatives and charitable organisations, in the production and consumption of spaces of care in settings set in, or serving, rural environments.     

'Gentrification' and desire

II y a moins de vingt ans, les vieux quartiers au coeur des villes canadiennes ou vivait la classe ouvrière étaient menacés de démolition. Maintenant à la mode et habités par une population financièrement à l'aise, ces quartiers sont une forme urbaine paradoxale. Il représentent d'une part la montée d'une structure économique désindustrialisée et dénationaliséd dans laquelle les citadins déclassés et les membres de la classe ouvriere sont marginalisés. D'autre part-et c'est là l'objet central de ce texte-il se trouve fossilisé dans les nouvelles textures de ces quartiers une critique immanente du développement urbain moderne. En ce sens, ces quartiers montrent comment, par l'intermédiaire de l'industrie culturelle, les pratiques culturelles marginales engendrent leur propre déplacement.
The old neighborhoods in Canadian inner cities that less than two decades ago were working-class housing threatened with demolition but have lately become fashionable and affluent are a paradoxical urban form. On the one hand, they represent the emerging dominance of a deindustrialized, denationalized economic structure and the irrelevance of working-class and underclass city dwellers to this process. On another hand-this paper's central theme-fossilized in the new landscapes of these neighborhoods is an immanent critique of modern city-building. In the latter respect, these areas illustrate how, by the workings of the culture industry, marginal cultural practice breeds its own displacement.     

The Migrant Mortality Advantage: A 70 Month Follow-up of the Brussels Population

There is considerable evidence that first generation immigrants to developed countries tend to have lower mortality than does the population as a whole at their destination. This advantage is usually ascribed to a selection process which makes migrants more robust than the local population and/or an acculturation process whereby third-world migrants lose their natural healthy life style as they take on modern urban dietary and living habits. We investigate immigrant-local mortality differences using a 6-year follow-up of the complete Brussels population aged 25–55, as enumerated at the Belgian census, 1991. We show that adult migrants have lower mortality than their native-born counterparts, despite their often poorer living arrangements, work status and human capital. This effect differs by origin group. The effects of age on mortality are similar for all groups, with mortality increasing about 8% a year. This increase is slightly greater for the Belgian born than for immigrants, which makes the selectivity explanation unlikely. Years since migration does not significantly increase the mortality risk for most groups, contradicting the acculturation hypothesis. Thus, explanations ascribing immigrants' mortality advantage to migrant selectivity, pre-modern cultural practices, or an artefact of population recording practices are insufficient. We propose, instead, an explanation based on the meaning migration has for the immigrant, and the hope engendered in the move, particularly that from a lesser to a more developed country.     

Managing the introduction of new technology

Most of the existing literature on the implications of new technology focuses on either its ‘impact’ or the social choices that lie behind strategies for its introduction into work organisations. The problems of managing the implementation of new technology have yet to be extensively examined despite this being one of the most critical aspects in the process of technological change. The findings from two case studies are presented which show how managers in the organisations concerned developed contrasting approaches to the problem of implementation in the context of opportunities and constraints presented by product markets and technological advance. Similarities between the two approaches are identified, in particular the role played by top management support in facilitating the acceptance of the new technology. The argument that management is able to develop a single unitary strategy towards the introduction of new technology is rejected in favour of a view of managerial actions as a series of flexible and changing sub-strategies associated with different stages in the process of change.
