Among a sample of college students, roughly 30% of the women and 12% of the men reported having been the victim of a sexual assault sometime in their lives. Of the assault victims, approximately 23% of both sexes stated that they had sexual intercourse with their assaulters on at least one subsequent occasion. Female victims of a completed sexual assault were significantly more likely to continue being sexually active with their assailants than were female victims who managed to block the assault, while no such difference was found for male victims. This would imply that some men are using assaultive tactics to secure sex partners beyond a single sexual episode, thereby enhancing their potential reproductive success in evolutionary terms. Also, men who committed sexual assault reported having had more lifetime sex partners than did sexually experienced men with no sexual assault history. Overall, the idea that sexual assault is part of an evolved reproductive strategy is consistent with findings from this study. 相似文献

Abstract: Intracerebral hemorrhage (ICH) is a well‐recognized complication of recreational cocaine use. The precise mechanism of the cocaine‐induced hemorrhagic event is unclear, although multiple factors have been implicated. We report a case of a 62‐year‐old woman who suffered left parieto‐occipital ICH with herniation and death, following a cocaine binge. Microscopic examination also revealed extensive cerebral amyloid angiopathy (CAA) in the vicinity of the hemorrhage. We additionally studied brain tissue in eight subjects between ages of 60 and 80 who were positive for cocaine metabolites at autopsy; of these, none had vascular amyloid‐β deposits by immunohistochemistry. Whereas we found no evidence that chronic cocaine use is a risk factor for CAA, given the age‐associated nature of CAA and the aging population using cocaine, CAA‐induced hemorrhage in the setting of cocaine use may be more common than recognized. This is the first reported case of CAA‐associated ICH precipitated by cocaine. 相似文献

In this paper we use a size and industry matched sample of over 1,900 UK and US businesses for the period 2004–05 in the manufacturing
and business services sectors to analyse the relative “strength” of the university–industry ecosystems in which these firms
operate in the two economies. Our analysis shows that in both countries universities per se play a quantitatively smaller
role as a source of knowledge for business innovation than either the business sector itself or a variety of organisations
intermediating between the university and business sectors. Our analysis reveals a much more diffuse university–industry ecosystem
in the UK in which a higher proportion of businesses claim links external to themselves in their pursuit of knowledge for
innovation and a higher proportion report directly connecting with universities. US firms are more likely to access knowledge
through a combination of business and intermediary sources and are less likely to have established formal collaborative or
partnership agreements in the 3 years prior to the survey. We also find, however, that a higher proportion of US firms place
a very high value on the connections they have with universities and are much more likely to commit resources to support such
innovation related university interactions. A similar pattern of diffuse but weaker links characterise the supply of public
sector financial assistance for innovation in our sample firms. UK firms are more likely to be in receipt of assistance, but
receive far less per firm in absolute terms and relative to their R&D expenditures. It appears that the UK university–industry
ecosystem is characterised by a greater width than quality of interaction. 相似文献

Police officers on the ground, as well as their senior officers, generally accept the view that arresting prostitutes and
their clients is simply not as important as arresting many other types of ‘offenders’. Police officer preferences and priorities
will differ such that the discretion applied to the enforcement of paid sex market related offences varies across locations.
Motivated by increasing policymaker interest in considering demand-side policies, a simple model is developed to help analyse
how clients will be likely to respond to enforcement level differences across jurisdictions. A range of policy implications
that arise are also identified and discussed. 相似文献

The nature of the risk or threat posed by ‘cyberfraud’ - fraud with a cyber dimension – is examined empirically based on data reported by the public and business to Action Fraud. These are used to examine the implications for a more effective risk-based response, both by category of fraud and also responding to cyberfraud generally, not just in the UK. A key characteristics of cyberfraud is that it can be globalised, unless there are major national differences in attractiveness of targets or in the organisation of control. This does not mean that all cyberfraud is international, however: not only do some involve face to face interactions at some stage of the crime cycle, but in online auction selling frauds, it appears to be common for the perpetrators and victims to reside in the same country. After reviewing patterns and costs of victimisation and their implications for control, the paper concludes that any law enforcement response must begin by being strategic: which other public and private sector bodies should be involved to do what; what should be the specific roles and responsibilities of the police and where ‘problem ownership’ should lie; what are we willing to pay for (in money and effort) for greater cybersecurity and how to reduce ‘market failure’ in its supply; and, how that security is going to be organised for and/or by the huge numbers of businesses and people that are (potentially) affected. 相似文献

Assessing Sexual Coercion: Survey Wording Differences and the Victimization-Perpetration Discrepancy
The current study examined the impact of item wording on self-reported sexual assault perpetration and victimization rates. The Sexual Experiences Survey (SES; Koss et al. in Journal of Consulting and Clinical Psychology, 55, 162–170, 1987) is a self-report assessment of female sexual victimization and male sexual perpetration. Studies using the SES consistently report a marked discrepancy between victimization rates and perpetration rates. The wording of the SES items asks respondents to report whether experiences occurred in the absence of female want. It was hypothesized that modified items, which did not require an analysis of female want, would yield increased male response rates compared to the original SES, but that female rates would be equivalent across versions. Parallel male and female SES items, for coercive sexual contact and intercourse, were compared with modified items. Analyses of the data confirmed the hypothesis that modified items yielded increased reports for males in the contact and intercourse conditions. Female response rates on modified items were increased in the contact condition, but not the intercourse condition. Implications of these findings were discussed. 相似文献

Prevalence and Predictors of Sexual Risks Among Homeless Youth 总被引:1,自引:0,他引:1
This study examined prevalence of sexual risks among homeless adolescents and described factors associated with those risks. Community-based outreach methods were used successfully to access this difficult-to-reach population. The sample included 203 homeless youth aged 15–22 recruited from community sites. Questionnaire items addressed demographics, sexual behaviors, alcohol/drug use, STI history and testing, and pregnancy history. In cross-sectional analysis, 58.7% of males and 75.6% of females reported recent sexual intercourse. Of those, one third of males and half of the females used no barrier method with at least one partner. Both gender (female) and race/ethnicity (non-Black) were associated with having intercourse without a barrier contraceptive method. Over one fifth reported a history of survival sex or receiving money, drugs, clothing, shelter, or food for sex. These results show disturbingly high rates of a number of sexual risks, reinforcing the need for targeted interventions with this highly vulnerable population. 相似文献
