The AIDS epidemic has made it imperative that sexual behaviour be changed. This paper examines heterosexual negotiation, which will form the focus for behaviour change. The processes involved in such negotiation are little understood.Research was carried out using the method memory work, which generated and theorised data relating to women's past experiences in sexual encounters. The method, originated by Haug, provides a way to examine how sexuality is produced and reproduced through reflection and reconstruction of past experiences. Memories are analysed by examining gaps and absences, cliches and metaphors, in the search for the common understandings and taken-for-granted assumptions which set the boundaries within which encounters take place.The memories obtained can be partly understood in terms of three discourses documented by Hollway. These are the male sex drive discourse, the have/hold discourse, and the permissive discourse. The data may also be understood in relation to three permissible figures for women identified in Irigaray's analysis, namely virgin, wife-mother, and whore. The paper acknowledges that these theoretical perspectives are quite distinct, even contradictory, but nevertheless finds that each in its own way illuminates the data. It is shown that some common understandings underlying sexual encounters render negotiation not only impossible but largely unintelligible. The permissive discourse may possibly provide space for some negotiation, but the paper concludes that it is essential to develop a truly woman-centered discourse of sexuality out of which male sexuality can be problematised. 相似文献

Decision-making is usually studied in the context of a particular choice or institution. This article proposes an alternative, cross-cutting approach. It argues that federal policy-making involves three forms of rationality — technical, economic and political. Standard operating procedures develop around each. This simplifies much decisionmaking but may also produce narrowness of outlook and a failure to see other dimensions to a policy problem. 相似文献

This paper considers the growing appeals to the idea of community in criminal justice policy and the involvement of actual communities in criminal justice initiatives. It draws on a completed two year research study of a number of community-based crime prevention initiatives in the South East of England. The paper considers the nature of community to which appeals are made in criminal justice discourse and policies, the contribution of community to the practices of social order and the nature of community representation and participation in crime prevention initiatives. It is argued that appeals to community in crime prevention, and crime control more generally, embody shifts in what constitutes the legitimate responsibilities of individuals, collectivities and the state. This has a number of implications, the first of which is a redrawing of the cost of policing and security services. Additionally, there is an associated shift in blame for failure. Finally, actual community involvement in crime control gives rise to new structures and forms of local governance that evoke key questions about the regulation of social relations, the nature of conflict resolution, citizenship, democracy and social justice. 相似文献

Telephone surveys were conducted over a three-year period on more than 800 Small Business Innovation Research (SBIR) Phase II projects initiated during the first three years of the program. For most of these projects, respondents were surveyed four years after receiving their Phase II award Five distinct levels of commercialization activity were identified ranging from “commercialization has occurred” (Level 1) to “commercialization is not expected” (Level 5). At the time of the survey, 12% of the projects had achieved commercialization (Level 1) and 18% were experiencing some commercialization success (Levels 1 and 2 combined). Of the participating federal agencies, the Department of Health and Human Services had by far the largest percentage of commercialized projects. For all agencies, over 60% of the respondents attributed nearly all of their projects' success to the SBIR program. Eighty-four percent stated that the technology development effort would not have been pursued without SBIR. Survey responses were also analyzed for a series of factors to determine their influence on the extent of commercialization activity. Factors included in the series are those related to the SBIR company conducting the project, the technology being developed, and marketing the product or service expected to be derived from the SBIR effort. 相似文献

Theories of federal grants to states and localities suggestthat these grants have a stimulative effect on spending, causingrecipient governments to expand and contract programs alongwith changes in the grants. However, policymakers may responddifferently to grant decreases than to grant increases becausethey face political and bureaucratic pressures to expand programs.These asymmetric reactions may depend on specific politicalstructures. Pooled time-series regressions of data from theAid to Families with Dependent Children program across 46 statesfrom 1965 to 1994 demonstrate state government responses togrant changes. Bureaucratic pressures and proposals lead statesto expand their welfare benefits upon increases in federal grants,but not to contract them upon decreases in federal grants. Withregard to the 1996 welfare reforms, this study indicates thatthe switch to block grants will lead to little or no state reductionin welfare payments. 相似文献

In situations where badly burnt fragments of bone are found, identification of their human or non-human origin may be impossible by gross morphology alone and other techniques have to be employed. In order to determine whether histological methods were redundant and should be superseded by biomolecular analyses, small fragments of artificially burnt bone (human and non-human) were examined by quantitative and standard light microscopy, and the findings compared with newer biomolecular analyses based on identifying specific human albumin by ELISA and amplifying human mitochondrial DNA by PCR. For quantitative microscopy, reference data were first created using burnt bones from 15 human and 20 common domestic and farm animals. Measured osteon and Haversian canal parameters were analysed using multivariate statistical methods. Highly significant differences were found between values for human and non-human bone, and a canonical discriminant function equation was derived, giving a predicted correct classification of 79%. For the main study, samples of cortical bone were taken from three fresh cadavers, six human skeletons and ten freshly slaughtered animals and burnt by exposure to temperatures ranging from 800 to 1200 degrees C; charred fragments of human cortical bone from two forensic cases were also tested. Quantitative microscopy and canonical discriminant function gave the correct origin of every sample. Standard microscopy falsely assigned burnt bone from one human skeleton and one forensic case to a non-human source, but otherwise gave correct results. Human albumin was identified in five individuals, including one of the forensic cases, but mitochondrial DNA could not be amplified from any of the human bone. No false positive test results were seen with either biomolecular method; and human albumin and mitochondrial DNA were correctly identified in all unburnt control specimens. It was concluded that histological methods were not redundant and that quantitative microscopy provided an accurate and consistent means of determining the human or non-human origin of burnt bone and was more reliable than standard microscopy or the newer immunological and DNA techniques tested here. 相似文献

This study links two previously unrelated lines of research: the lack of comprehension of capital penalty-phase jury instructions and discriminatory death sentencing. Jury-eligible subjects were randomly assigned to view one of four versions of a simulated capital penalty trial in which the race of defendant (Black or White) and the race of victim (Black or White) were varied orthogonally. Dependent measures included a sentencing verdict (life without the possibility of parole or the death penalty), ratings of penalty phase evidence, and a test of instructional comprehension. Results indicated that instructional comprehension was poor overall and that, although Black defendants were treated only slightly more punitively than White defendants in general, discriminatory effects were concentrated among participants whose comprehension was poorest. In addition, the use of penalty phase evidence differed as a function of race of defendant and whether the participant sentenced the defendant to life or death. The study suggest that racially biased and capricious death sentencing may be in part caused or exacerbated by the inability to comprehend penalty phase instructions. 相似文献
