The purpose of the current study was to determine if college students' retrospective reports of family-of-origin physical abuse were related to their current reports of depressed symptomology, hopelessness, and suicidal and life-threatening behavior. Consistent with hypotheses, abuse by a parent (physical and psychological) and physical perpetration toward a parent were associated with increased rates of suicidal and life-threatening behavior. Gender of the parent was also shown to be important as symptoms of depression were related to mother but not father victimization and perpetration. Contrary to expectation, witnessing parental spouse abuse was not associated with young adults' current symptoms of depression, hopelessness, and suicidal and life-threatening behavior. These findings were interpreted with regard to the intergenerational transmission of violence theory.  相似文献

In mortality research, much attention has been paid to the strong geographical differentials in mortality levels and in modern mortality decline, as the analysis of this geographical differentiation might hold the key to explaining the determinants of mortality change. The use of historical cause-specific mortality data has proved a challenging, although very insightful, means to this end. The four contributions to this special issue focus on cause-specific mortality in the past, both to reassess older data using new insights and to challenge existing insights by using new data and methods. These papers, of which earlier versions were presented during the thirty-eighth Social Science History Association (SSHA) Meeting in Chicago, 21–24 November 2013, explore mortality at different stages of the life course, ranging from early infancy to old age. Moreover, each paper revolves around a different group of causes of death. Although the papers are in many ways rather different, together they demonstrate how different data, theoretical frameworks and methodologies can push the boundaries of research into the trends and determinants of historical mortality patterns.  相似文献

Disasters such as flash flooding, mass shootings, and train and airplane accidents involving large numbers of victims produce significant opportunity for research in the biosciences. This opportunity exists in the extreme tails of life events, however, during which decisions about life and death, valuing and foregoing, speed and patience, trust and distrust, are tested simultaneously and abundantly. The press and urgency of these scenarios may also challenge the ability of researchers to comprehensively deliver information about the purposes of a study, risks, benefits, and alternatives. Under these circumstances, we argue that acquiring consent for the immediate use of data that are not time sensitive represents a gap in the protection of human study participants. In response, we offer a two-tiered model of consent that allows for data collected in real-time to be held in escrow until the acute post-disaster window has closed. Such a model not only respects the fundamental tenet of consent in research, but also enables such research to take place in an ethically defensible manner.  相似文献

Contact and close‐range gunshot injuries can produce bloodstains on the shooting hand and weapon. In this study, backspatter was analyzed in experimental horizontal pistol shots into blood‐filled sponges. The shooting distances were set between 0 and 45 cm. With increasing shooting distance, there was a significant decrease in the degree of backspatter. Microspatter could be detected on the weapon and shooting hand up to a shooting distance of 40 cm. They were predominantly located on thumb and index finger as well as the radial dorsal aspects of the hand. Fine spray of microspatter combined with elongated droplets in the shape of exclamation marks was found at contact and 2‐cm distance shots. An angular calculation based on the shape of the bloodstains was possible up to a shooting distance of 2 cm. No bloodstains were detected beyond 45 cm.  相似文献

This note focuses on the best means for achieving civilian control of border security in the Balkans. Civilian control may be achieved through societal control (as in civilian complaint reviews) but such procedures require an established political culture that does not yet exist in the region. Civilian control also requires a degree of technical expertise, which is not always available among international officials, let alone local communities.  相似文献
