This study examined the association of victimization in a physically violent dating relationship with risk behaviors, age of risk behavior initiation, and co-occurrence of risk behaviors among students in grades 9 through 12 in the United States. Data were from the 2003 national Youth Risk Behavior Survey (YRBS). Nearly 9% of students reported experiencing dating violence victimization. Dating violence victimization was associated with alcohol use, marijuana use, and having ever had sexual intercourse among female students and having ever had sexual intercourse among male students. Dating violence victimization also was associated with early initiation of alcohol use among female students. The odds of dating violence victimization increased as the number of risk behaviors increased and as the number of lifetime sexual partners increased. These risk behavior patterns should serve as warning signs of elevated risk for dating violence victimization and may be helpful in identifying adolescents who could benefit from targeted, preventive interventions. 相似文献

In this article we examine the rate at which patent applications are granted as a function of the inventor's race and gender. Empirical analysis of more than 3.9 million U.S. applications finds minority and women applicants are significantly less likely to secure a patent relative to the balance of inventors. Further analysis indicates that a portion of this bias is introduced during prosecution at the Patent Office, independent of the quality of the application. Mechanisms underlying these disparities are explored. The article concludes with a discussion of our results and their interaction with patent law, innovation policy, and employment trends. 相似文献

The storage and use of explosives is regulated at the state and federal level, with a particular focus on physical security and rigorous accounting of the explosive inventory. For those working with explosives for the training and testing of explosive-detecting canines, cross-contamination is an important concern. Hence, explosives intended for use with canine teams must be placed into secondary storage containers that are new, clean, and airtight. A variety of containers meet these requirements and include screw-top glass jars (e.g., mason jars). However, an additional need from the explosive-detecting canine community is secondary containers that can also be used as training aids whereby the volatiles emitted by explosives are emitted in a predictable and stable manner. Currently, a generally accepted method for the storage of explosives and controlled emission of explosive vapor for canine detection does not exist. Ideally, such containers should allow odor to escape from the training aid but block external contaminates such as particulates or other volatiles. One method in use places the explosive inside a permeable cotton bag when in use for training and then stores the cotton bag inside an impermeable nylon bag for long-term storage. This paper describes the testing of an odor permeable membrane device (OPMD) as a new way to store and deploy training aids. We measured the evaporation rate and flux of various liquid explosives and volatile compounds that have been identified in the headspace of actual explosives. OPMDs were used in addition to traditional storage containers to monitor the contamination and degradation of 14 explosives used as canine training aids. Explosives were stored individually using traditional storage bags or inside an OPMD at two locations, one of which actively used the training aids. Samples from each storage type at both locations were collected at 0, 3, 6, and 9 months and analyzed using Fourier Transform Infrared (FTIR) Spectroscopy and Gas Chromatography–Mass Spectrometry (GC–MS) with Solid-Phase Microextraction (SPME). FTIR analyses showed no signs of degradation. GC–MS identified cross-contamination from ethylene glycol dinitrate (EGDN) and/or 2,3-dimethyl-2,3-dinitrobutane (DMNB) across almost all samples regardless of storage condition. The contamination was found to be higher among training aids that were stored in traditional ways and that were in active use by canine teams. 相似文献

Children and adolescents who are having difficulty coping with stress often present with complaints of physical discomfort. Effective treatment approaches exist for many of these issues. Among high-conflict parents, however, children's medical issues can become another canvas for conflict, with parents focused more on blaming one another for the child's distress than on options for assisting the child. Professionals can be drawn into the conflict to such a degree that they overlook essential steps for addressing and managing these issues. The authors present a research-informed model for managing medical and psychophysiological issues amid parental conflict. 相似文献

Australia has well‐established conventions for caretaker governments. These conventions regulate how a government should operate once an election is called, and have been documented for some decades. Yet the current conventions date from an era when elections usually produced clear and immediate results. Can our caretaker conventions cope with the emerging reality of indecisive elections and long delays before a new government is confirmed? This paper canvasses the state of Australia's caretaker conventions and offers suggestions for an expanded, contemporary code. 相似文献
