Over the past decade, a contentious debate regarding delayed memories of childhood sexual abuse (CSA) has existed. In order to address this debate, 240 female participants completed questions about CSA, the Dissociative Experience Scale (Bernstein & Putnam, 1986), Perceived Emotional Closeness with Perpetrator Scale (Schultz, Passmore, & Yoder, 2000), and the Gudjonsson Suggestibility Scale 2 (GSS 2) (Gudjonsson, 1987). Eighty-two (36%) reported CSA and 37% of these indicated memory disturbances for the CSA. Participants reporting memory disturbances also reported significantly higher numbers of perpetrators, chemical abuse in their families, and closer relationships with the perpetrator(s) than participants reporting no memory disturbances. Implications for clinicians working with clients reporting CSA are discussed. 相似文献

Protective capacity is the 'extra' capacity placed at non-bottleneck resources to absorb random disruptions in planned levels of performance so that the bottleneck resource continues to be effectively utilized. A full factorial experiment with a simulation model was conducted to explore issues associated with the quantity and location of processing variance in a five-station manufacturing cell. The cell's performance was measured using both mean flow time ( MFT ) and bottleneck shiftiness ( SHIFT ) for 3 patterns of variance for the non-bottlenecks at 5 different levels of variation. In order to investigate the importance of the quantity of added capacity on the variation both a low level of protective capacity (10%) and a high level (50%) were considered. The results indicate that having the higher variation work centres close to the bottleneck provides reduced MFT and SHIFT . The performance measures improved at both the low and high setting of protective capacity. 相似文献

We describe a quasi-experimental trial of time-limited family therapy with veterans and families of veterans who served in Europe, outside the war zone, during Operation Desert Storm (ODS). Family systems therapy was provided both to individuals and conjointly to couples or families during the acute postwar readjustment period. The intervention adapted strategies from structural, strategic, intergenerational, and behavioral family therapies in a brief-treatment protocol for systemic stressor resolution. Veterans given family system therapy were able to resume functional levels of psychosocial adjustment and reduce the risk of long-term (Chronic or delayed) psychosocial impairment. Based on these preliminary findings, controlled evaluation of family systems therapy appears warranted for indi- 相似文献

American ecologists recently began to address the ecology of cities. Concurrently, higher education institutions have developed sustainability education programs and instituted sustainability policies and projects. This paper draws together these two disparate areas by examining the nitrogen (N) budget of the Twin Cities campus of the University of Minnesota. We addressed the question: what were the annual inputs, outputs and internal cycles of N on the University of Minnesota Twin Cities campus? We found that 508 Mg N yr-1 were brought into the campus and 494 Mg N yr-1 were emitted from the University of Minnesota campus. The largest N inputs were abiotic fixation (conversion of N2 to NOx by combustion) and food for humans and animals. The largest N output was NOx, followed by wastewater. Our results expand the understanding of the ecology of institutions within an urban area and provide an opportunity for improving urban ecology education and environmental policy at educational institutions. 相似文献

Local action for biodiversity is essential to ensure better conservation status for biodiversity and maintain ecosystem services. In many places the rich biodiversity is still relatively untouched and represents an outstanding asset for local sustainable development. The loss of biodiversity occurs mainly because of rapid changes in land use, urban sprawl, infrastructure development, acidification, eutrophication, desertification, overexploitation, intensification of agriculture, tourism development and climate change. There is a clear need for a more flexible, people-oriented and visionary approach for sustainable use of biodiversity resources. This article concerns “Local Biodiversity Action Plans”, which provide a comprehensive and integrated approach to biodiversity and ecosystem services for the sustainable development of rural municipalities and their local communities. Although biodiversity action planning is not a new concept, bringing a plan to life has significant societal benefits with innovative solutions to help biodiversity conservation while entailing close interaction of science, policy and society. This approach was developed together with project partners and local communities in selected regions of the Western Balkans and it benefits from a range of stakeholders, including social and natural scientists, practitioners, elected representatives of the local communities and end users in the frame of a participatory approach. The conclusion of this article discusses the role of communication and outlines the critical success factors and the challenges ahead for the future. 相似文献
