According to recent research, interactions between infant health and environment can play crucial roles in clustering health and economic disadvantage among certain families. Researchers have provided a clear example of such intergenerational biosocial cycles when they document that interactions between parental low birth weight status and prenatal environment are associated with the risk of a low birth weight, and that interactions between a child's birth weight status and early childhood environment are associated with adult socioeconomic outcomes. In this article, we consider how existing policies may be revised to more effectively address such interactions between social and biological risk categories. We are particularly concerned in this discussion with revising risk categories so they can encompass biological risk, social risk, and developmental frameworks. A framework of biosocial risk is quite flexible and may be applied to a variety of issues and programs; however, in this article we focus on the single case of low birth weight to illustrate our argument. In considering specific applications, we further explore how attention to biosocial interactions may reshape Medicaid, special education, the Earned Income Tax Credit, and Temporary Assistance for Needy Families. 相似文献

Social capital, social liabilities, and political capital: Social networks and informal manufacturing in Nigeria 总被引:1,自引:0,他引:1
This article addresses the question of why social networks havefailed to promote economic development in Africa when they havebeen associated with economic growth in other parts of the world.Detailed field research traces the role of social networks inthe economic organization of two dynamic informal enterpriseclusters in the town of Aba in south-eastern Nigeria, an arearenowned for the density of its popular economic networks andfor the rapid development of small-scale manufacturing underNigerias structural adjustment programme. Focusing onthe role of embedded social institutions and their restructuringamid the competitive pressures of rapid liberalization, I considerthe extent to which social networks in Aba constitute socialcapital capable of promoting economic development inthe context of ongoing liberalization, social liabilitiesthat undermine accumulation through a social logic of redistributionand parochialism, or political capital throughwhich popular forces are incorporated into the shadowstructures of predatory states. This article challengesthe essentialism of much of the contemporary literature on Africansocial networks, arguing for a sharper focus on the specificinstitutional capacities of indigenous economic institutions.It calls for greater attention to the role of rapid liberalizationand state neglect in explaining the developmental failures ofAfrican informal enterprise networks. 相似文献

The detection of a mixture of nine explosive compounds, including nitrate esters, nitroaromatics, and a nitramine in less than 140 sec is described. The new method employs a commercially available pulsed-discharge electron capture detector (PDECD) coupled with a microbore capillary gas chromatography (GC) column in a standard GC oven to achieve on-column detection limits between 5 and 72 fg for the nine explosives studied. The PDECD has the benefit that it uses a pulsed plasma to generate the standing electron current instead of a radioactive source. The fast separation time limits on-column degradation of the thermally labile compounds and decreases the peak widths, which results in larger peak intensities and a concomitant improvement in detection limits. The combination of short analysis time and low detection limits make this method a potential candidate for screening large numbers of samples that have been prepared using techniques such as liquid-liquid extraction or solid-phase microextraction. 相似文献

This paper examines principles of feminist research and discusses the authors' attempts to use these principles in a systematic way in their own research. Three principles of feminist research are identified: research should contribute to women's liberation through producing knowledge that can be used by women themselves; should use methods of gaining knowledge that are not oppressive; should continually develop a feminist critical perspective that questions dominant intellectual traditions and can reflect on its own development.Consciously applying these principles in a research study of the relation between changes in consciousness and the changes in the structural situation of individuals raised several methodological issues and dilemmas. These include the impossibility of creating a research process that completely erases the contradictions in the relationship between the researcher and the researched; the difficulties in analysing change as a process; the tension between the necessity of organizing the data and producing an analysis which reveals the totality of women's lives; and problems of validity, particularly those raised when the research process becomes part of the process of change. 相似文献

This article uses a case-study of the relationship between the British suffrage organization, the Women's Social and Political Union, and its equivalent on the Irish side, the Irish Women's Franchise League, in order to illuminate some consequences of the colonial relationship between Britain and Ireland. As political power was located within the British state, and the British feminist movement enjoyed superior resources, the Irish movement was at a disadvantage. This was compounded by serious internal divisions within the Irish movement - a product of the dispute over Ireland's constitutional future - which prevented the Franchise League, sympathetic to the nationalist demand for independence - from establishing a strong presence in the North. The consequences of the British movement organizing in Ireland, in particular their initiation of a militant campaign in the North, are explored in some detail, using evidence provided by letters from the participants.British intervention was clearly motivated from British-inspired concerns rather than from any solidarity with the situation of women in Ireland, proving to be disastrous for the Irish, accentuating their deep-rooted divisions.The overall argument is that feminism cannot be viewed in isolation from other political considerations. This case-study isolates the repercussions of Britain's imperial role for both British and Irish movements: ostensibly with a common objective but in reality divided by their differing response to the constitutional arrangement between the two countries. For this reason, historians of Irish feminist movements must give consideration to the importance of the ‘national question’ and display a more critical attitude towards the role played by Britain in Irish affairs. 相似文献
