Martin Schmeiser 《Soziologie》2006,35(2):178-191
The article analyzes the consequences of the marginal status of the Sociology of Professions in Germany during the last decades on the efforts of the new working group “Sociology of Professions.” This new working group has been established in order to make professions an attractive research topic. First it will be demonstrated that a lack of a solid grounding in the international literature influences the new efforts to publish textbooks. Second it will be shown that there is a missing historical perspective in the old and new sociology of professions in Germany. Finally everything seems to indicate that the new working group is more interested in questions of general sociology and occupational sociology than in questions of a sociology of professions. 相似文献

‘The Effect of Social Networks at Origin
Communities on Migrant Remittances: Evidence from Nang Rong District’ 总被引:1,自引:0,他引:1
Martin Piotrowski 《Revue europeenne de demographie》2006,22(1):67-94
The literature on the effect of social networks on migrant remittances has ignored the influence of a household’s embeddedness in social networks in the origin community. This paper, using multilevel statistical modeling and social survey data from Nang Rong district in Thailand, examines how remittances between migrants and origin households are associated with social networks. Social network measures come from data on sibling and rice harvest network ties. Rice harvesting is very important to the rural economy, and households participating in the network are privy to vital sources of news and information that spread through the network. Results support the notion that migrants remit less to households that are isolates in the rice-harvesting network, which is theorized to be associated with access to information about employment options. 相似文献

This essay examines the historical and theoretical development of sexuality in migration research. Noting gaps and omissions in the literature, the essay proposes a dual notion of sexuality including one that is produced by the intersection of other social identities such as class and race, and a queer studies‐derived idea of the sexual that goes against the normalizing of heterosexual institutions and practices. Utilizing a case study of Filipina migrant workers, the essay demonstrates the pivotal role of sexuality in the future of gender and migration research through a critique of the implicit normative assumptions around family, heterosexual reproduction, and marriage that abound in this body of literature, and how a critical notion of sexuality enables a more inclusive and accurate portrait of global gendered migration. 相似文献

Conclusion The Independent Sector approach to measuring the US non-profit sector, as summarised inThe Almanac, provides a valuable and instructive model for European and other attempts to describe and measure the sector. The aim of mappers in those other countries should not be to replicateThe Almanac, but to imitate its broad approach, using it to stimulate and encourage statistical efforts elsewhere. Although the time for whole-Europe mappings has not yet come — in fact, it is very many years away — individual European countries could and should make substantial progress. As I have argued, progress will generally be greatest when an imaginative blend of five main approaches is employed. This is exemplified by the Independent Sector's work, and would-be mimics should endeavour to match both this blending and the energy and zest with which the task has been tackled.Professor of the Economics of Social Care and Deputy Director of the Personal Social Services Research Unit, University of Kent at Canterbury and Co-editor,Voluntas.I would like to acknowledge a number of European colleagues whose comments assisted my preparation of this paper, in particular Edith Archambault, Paulo Barbetta, Andrea Bassi, Rudolph Bauer, Andrew Crook, Jim Jackson, Jeremy Kendall, Éva Kuti, Susan Saxon-Harrold, Wolfgang Seibel, Justin Davis Smith and Tymen van den Ploeg.

Daughters from low‐income families who did not receive Aid to Families with Dependent Children (AFDC) are compared to daughters from low‐income families who did receive assistance to better account for family income in the intergenerational association of AFDC. The research models the timing of a daughter's first birth and, for those who become mothers, the number of years a daughter receives any AFDC. Women whose families received AFDC during their childhood are more likely to receive AFDC as adults relative to those women whose families did not receive AFDC. Controlling for family income in a more careful and comprehensive way than past research explains part but not all of the effects of childhood AFDC receipt. Among daughters from chronically poor families, however, parental AFDC use is not associated with additional years of AFDC participation. Although the present research cannot confirm or deny a causal role for parental welfare use, the intergenerational transmission of financial resources does explain part of the intergenerational association of welfare use. 相似文献

Sources of drug information among adolescent students 总被引:1,自引:0,他引:1

A sample of 1023 eighth and tenth grade students in small to medium-sized central Texas school districts was assessed to determine the amount of information they receive from ten sources about six categories of drugs. The amount of information males reported receiving about each drug category was significantly greater than what females reported, and the amount of information that eighth graders reported receiving about each drug category was significantly greater than what tenth graders reported. Television was the primary source of drug information for all categories of drugs except inhalants, for which friends and television were equally important sources. Parents and printed media (magazines or newspapers) were of secondary importance, followed by friends and teachers. Adolescents were less likely to receive drug-related information from experience, siblings, church, doctors, and police. The reliance on the mass media for drug information in smaller school districts is a pattern which has been previously observed in larger urban districts. This consistency suggests that mass media approaches to drug education are likely to be as effective in rural areas and smaller towns as they are among urban adolescents. Implications for television programming are discussed. 相似文献
