One topic of debate within the field of intimate violence involves the equivalence, or lack thereof, of male-perpetrated versus female-perpetrated violence. To inform this debate, we examined potential gender-related differences in the frequency of sustaining violence, the severity of violence sustained, and effects of violence on relationship satisfaction. Data were collected from 2 samples of heterosexual undergraduates in dating relationships. In both studies, men and women experienced violence at comparable frequencies, although men experienced more frequent moderate violence. Rates of severe violence were extremely low for both sexes across studies. In both investigations, only women experienced lower relationship satisfaction as a function of partner violence. In Study 1, relationship status moderated this effect, such that women in serious dating relationships were less satisfied than either women in less serious relationships or than men as a function of partner violence. In Study 2, women were less satisfied with violent relationships than men regardless of relationship status. We contend that gender-sensitive approaches to relationship violence are important to better understand and prevent both male- and female-perpetrated violence. Directions for future research efforts are outlined.  相似文献

Abstract: This study explores the views of Victorian Chief Administrators (CAs) about their jobs. CAs report that the environment of administration has changed in three broad areas: greater public expectations, a breakdown of the politics-administration dichotomy and difficulties reconciling managerial accountability with limited managerial autonomy. In response, CAs describe a distinctive pattern of concerns — with the "what", "why" and "how" of agency operation. First, they attempt to shape the "what" or the ends and values their agency creates. Second, they act to enhance the "why" or their agency's legitimacy and the support it attracts from constituencies. Third, CAs are concerned with "how" to mobilise organisational resources, particularly by moulding culture towards the agency values they identify. These findings suggest that CAs have devised understandings of their responsibilities which conform more to theoretical conceptions of leadership than either administration or management. The research points to the emergence of a distinctive type of administrative leadership.  相似文献

An integrated lab-on-a-chip system has been developed and successfully utilized for real-time forensic short tandem repeat (STR) analysis. The microdevice comprises a 160-nL polymerase chain reaction reactor with an on-chip heater and a temperature sensor for thermal cycling, microvalves for fluidic manipulation, a co-injector for sizing standard injection, and a 7-cm-long separation channel for capillary electrophoretic analysis. A 9-plex autosomal STR typing system consisting of amelogenin and eight combined DNA index system (CODIS) core STR loci has been constructed and optimized for this real-time human identification study. Reproducible STR profiles of control DNA samples are obtained in 2 h and 30 min with ≤0.8 bp allele typing accuracy. The minimal amount of DNA required for a complete DNA profile is 100 copies. To critically evaluate the capabilities of our portable microsystem as well as its compatibility with crime scene investigation processes, real-time STR analyses were carried out at a mock crime scene prepared by the Palm Beach County Sheriff's Office (PBSO). Blood stain sample collection, DNA extraction, and STR analyses on the portable microsystem were conducted in the field, and a successful “mock” CODIS hit was generated on the suspect's sample within 6 h. This demonstration of on-site STR analysis establishes the feasibility of real-time DNA typing to identify the contributor of probative biological evidence at a crime scene and for real-time human identification.  相似文献
