Data from the Centers for Disease Control and Prevention (CDC) 1993 Youth Risk Behavior Surveillance (YRBS) of a sample of U.S. female adolescents (N = 7839) were compared to a cohort of 9th through 12th grade high performance female athletes (N = 141) with regard to risk-taking behavior on eight items related to sexual activity (i.e., ever engaged in sexual intercourse, age of first sexual intercourse, number of lifetime sexual partners, current sexual activity, condom use, use of the birth control pill, contracting a sexually transmitted disease (STD), and incidence of alcohol or drug use prior to last sexual activity). Chi-square analyses (p < .05) showed that with the exception of alcohol or drug use prior to last sexual activity, and use of birth control pills, the six other risk-taking behaviors were significantly different between the U.S. female sample and the female athletes. In all instances, except for contracting an STD, U.S. females reported engaging in sexual risk-taking behaviors more frequently than the high performance athletes, and furthermore, were more likely to be sexually active than the high performance athletes (50% vs. 21%). Among the high performance athletes, only lifetime sexual activity showed significant difference by grade, with sophomores and seniors reporting more frequent involvement in sexual activity. These findings suggest that participation in a high performance sports activity is positively associated with some reduced sexual risk-taking behaviors for adolescent females.相似文献

Security incidents such as targeted distributed denial of service (DDoS) attacks on power grids and hacking of factory industrial control systems (ICS) are on the increase. This paper unpacks where emerging security risks lie for the industrial internet of things, drawing on both technical and regulatory perspectives. Legal changes are being ushered by the European Union (EU) Network and Information Security (NIS) Directive 2016 and the General Data Protection Regulation 2016 (GDPR) (both to be enforced from May 2018). We use the case study of the emergent smart energy supply chain to frame, scope out and consolidate the breadth of security concerns at play, and the regulatory responses. We argue the industrial IoT brings four security concerns to the fore, namely: appreciating the shift from offline to online infrastructure; managing temporal dimensions of security; addressing the implementation gap for best practice; and engaging with infrastructural complexity. Our goal is to surface risks and foster dialogue to avoid the emergence of an Internet of Insecure Industrial Things. 相似文献
In this article, we question the apparent simplicity of medical law's construction of 'life and death' cases as a clash between the sanctity of life principle and patient autonomy. Our main purpose in doing so is to try to understand more fully the nature of law's regulation of the existence and non-existence of life. Specifically, we argue that, by broadening the understanding of autonomy in this area beyond a simple concern for patients' rights and self-determination, to include a focus on the individual generally, it becomes possible to identify some of the legal practices that are central to the manner in which law regulates the threshold between life and death. Through an analysis of a recent case in English law--Re B (an adult: refusal of medical treatment)--(although Australian jurisdictions presently disclose no similar, authoritative case, ours presently is almost an arbitrary choice)--we demonstrate the central role played in this regulation by tests for mental capacity, questions of character, explanation, and imagination. We conclude that medical law, at least in this context, can be theorised as a normalising practice--one in which the determination of norms often occurs through patients. 相似文献
Mental health problems and the services to address them are currently receiving more attention in the UK than ever. Mental health care in England--indeed, across the UK--is experiencing a much needed transformation. It is therefore highly pertinent to examine the patterns of psychotropic medication use, given their intended links to recovery, rehabilitation, and reintegration, as well as to explore the economic and other factors that appear to influence those patterns. These are the aims of this paper. Our attention will be primarily focused on England. What this analysis shows is that given a higher profile by government, including additional funding (although not really benefiting differentially compared to other parts of the health service) and the first national service framework, it is possible to see changes in service patterns, access and (to a degree) outcomes. These changes are occurring at a time when new classes of psychotropic medication are being introduced in a range of therapeutic areas, contributing to the relatively rapid growth of take-up but also raising questions about appropriateness, effectiveness, cost-effectiveness and equity. 相似文献
