A theoretical understanding of the gendered contours of structural, everyday and symbolic violence suggests that young addicted women are particularly vulnerable to the infectious diseases caused by injection drug use-especially hepatitis C. Participant-observation fieldwork among heroin and speed addicts in San Francisco's Haight Ashbury neighborhood reveals that extreme levels of violence against women are normalized in the common sense of street-youth drug culture. Physical, sexual and emotional violence, as well as the pragmatics of income generation, including drug and resource sharing in the moral economy of street addicts, oblige most young homeless women to enter into relationships with older men. These relationships are usually abusive and economically parasitical to the women. Sexual objectification and a patriarchal romantic discourse of love and moral worth leads to the misrecognition of gender power inequities by both the men and women who are embroiled in them, as well as by many of the public services and research projects designed to help or control substance abusers. Despite deep epistemological, theoretical and logistical gulfs between quantitative and qualitative methods, applied public health research and the interventions they inform can benefit from the insights provided by a theoretical and cross-methodological focus on how social power contexts shape the spread of infectious disease and promote disproportional levels of social suffering in vulnerable populations.  相似文献

Data from the three Norwegian censuses of 1960, 1970 and 1990 combined with information on migration status and survival between 1970 and 1985 have permitted the estimation, though logistic modelling, of the predictive abilities of different socio-economic indicators on the risk of death by cause. The risk has also been measured for each indicator separately, according to the path followed by the individual between 1960 and 1980. The study shows very strong disparities in risk both for men and for women, as well as a moderate reduction in differences in risk by age. The study also shows, among other things, the importance of taking account of socio-economic information covering as long a period as possible and to consider the cause of death in the study of differential mortality through a life-history approach.  相似文献

In the aftermath of the 1974–1975 oil crisis, an increasing number of business and government leaders in Europe have advocated a reinforcement of protectionist measures in order to cope with competition from the newly industrializing countries, and in particular from the Asian ‘gang of four’. So far there is no evidence that trade with the NICs has resulted in net losses in terms of employment. The Asian NICs are eager to absorb new technology and to develop their industries towards sophisticated high value added sectors. This creates new opportunities for European companies to export intermediate products, capital goods, and to foster their foreign direct investment in the region.  相似文献

Auditory hallucination, or hearing voices, is generally associated with psychopathology. In psychiatry it is inter-preted as a symptom of an illness, with no connection to the individual's life history. Voice hallucinations in childhood occur in a variety of contexts and have variable long-term outcomes. Little is known about the course of the experience. In this study, 80 children and youngsters hearing voices were interviewed on four occasions over a period of three years about the content of the voices and their overall experience of voices, focusing on the determinants for a promising outcome in the pathways through care. The results indicate that the need for care in the context of the experience of voices is associated not only with high levels of problem behaviour and associated negative symptoms of psychosis, but also, independently, with an appraisal of the voices in terms of anxiety, depression, dissociation and frequency of occurrence. In 60 per cent of the participants the voices disappeared during the three-year research period. The relationship between the disappearance of voices and the course of mental health treatment is, however, ambiguous.  相似文献

The outranking methods usually contain two main steps: determination of a (sometimes valued) relation which aggregates the preferences and exploitation of this relation in order to choose, sort or rank the actions. In a ranking problem, the second step is the construction of a (complete or partial) preorder from a (valued) relation. We have considered it was interesting to list the good properties such a construction should verify and to analyze some procedures in this context. We present here the first results of this study, which concern the construction of a complete preorder from a non valued relation.  相似文献

Rushton's theory of r-K race differences was examined in relation to the rate of murder, rape, and serious assault per 100,000 population and Gross Domestic Product per Person for 74 countries from the 1993–1996 International Crime Statistics published by INTERPOL and the 1999 CIA World Fact Book. Each country was assigned to one of the three macro-races East Asian, European, and African. The results corroborated earlier findings that violent crime is lowest in East Asian countries, intermediate in European countries, and highest in African and in Black Caribbean countries. The median number of violent crimes per 100,000 population were: 7 East Asian countries—34; 45 European countries—42; and 22 African and Black Caribbean countries—149, respectively. The median Gross Domestic Product per Person was highest in East Asian countries ($12,600), intermediate in European countries ($7,400), and lowest in African and Black Caribbean countries ($1,900). Across the three population groups there was an ecological correlation of –.96 between crime and wealth (wealthier countries had less crime). Finer-grained analyses, however, found that while wealth was negatively related to crime across European or East Asian countries, it was positively related to crime for the African and Black Caribbean countries (i.e., the wealthier an African or Black Caribbean country, the greater its rate of violent crime). Future research needs to examine genetic factors in addition to cultural factors as well as their interactions.  相似文献

This paper models optimal release prices of an experience good recurrently issued on markets. Using a sample of Bordeaux wines, we find that using a minimal number of intrinsic and extrinsic attributes is sufficient to explain a large proportion of release prices. We further observe a significant relationship between primary market prices and secondary market prices and general economic conditions. Release prices can deviate from secondary market prices in the short run but remain aligned over the long run. Finally, an out-of-sample analysis indicates that short-run mispricing directly affects the purchase behavior of customers.  相似文献
