Suicide by cop has become a familiar topic among members of law enforcement, mental health professionals, and the general public. This paper presents two cases where police officers chose to commit suicide by getting other police officers to kill them. The two police officers studied, by examination of closed case files, were found to be similar to civilians who committed suicide by cop on several demographic (gender, age, history of mental illness, and suicide attempts), and situational (stress factors, trigger) variables. The cases help us to understand possible motives and management for individuals who choose to end their life in this manner. 相似文献

Non-fiction books by and about Aboriginal and Torres Strait Islanders have arguably played a crucial role in the framing of public discussion of Indigenous issues in Australia since the 1950s. In this article, I track quantitative trends in the publishing of the approximately 769 such books for the Australian retail trade between 1960 and 2000, as part of what I describe as an emerging “cultural mission” among Australian book publishers through the period. The article then discusses two major trends within the data. The first is an overall increase in the number of titles published annually through the period, while the second is a declining interest by mass-market trade publishers in publishing books in the area from the 1980s onwards versus an increased publication rate by smaller independent presses and two large trade publishers with a particular interest in the area, one of which is also independently owned. The article concludes with a discussion of possible reasons for the latter trend in the context of ongoing debates about white Australian colonialism. 相似文献

Pulmonary embolization of cerebral tissue as the result of severe head trauma is an uncommon, if not rare, phenomenon, and few cases have been reported in the literature. The authors discuss the case of a 51-year-old male who died six days after suffering extensive head trauma in a motor vehicle collision. At autopsy, white-gray emboli were found in several subsegmental pulmonary arteries. The results of histologic examination with the hematoxylineosin stain gave the impression that the emboli were necrotic cerebral tissue; however, routine special stains for neural tissue produced inconclusive results. Immunohistochemical staining of the emboli with monoclonal mouse anti-human neurofilament protein (Dako Corp., Carpinteria, California) confirmed the cerebral nature of the emboli. To the authors' knowledge, this is the first reported case of pulmonary embolization of cerebral tissue confirmed by immunohistochemistry. 相似文献

Two six-shot suicides are reported that occurred in adjoining counties in Ohio eleven-and-one-half weeks apart. There is no indication of any connection between victims, and it is doubtful that the second individual knew of the first death since there was no news media coverage of the first death. The most significant points of commonality between the two cases are the location of the gunshot wounds (anterior chest and upper abdomen) and the responses of disbelief from those outside the medicolegal professions. Knowledge of such cases with a high number of shots and more than one fatal wound can assist death investigators in confronting similar cases. 相似文献

The effects of programmed peer- and adult-mediated play initiations were compared for socially dysfunctional, maltreated preschool children. An N = 1, alternating treatments design was used to compare these strategies. Two withdrawn nonmaltreated (control), two withdrawn maltreated, and three aggressive maltreated children served as subjects. Dyadic play sessions were videotaped and rated at the completion of the study by naive raters according to an 18-category observation system. Overall, the control children showed no difference in levels of interaction between peer and adult conditions. The withdrawn maltreated children showed a clear preference for interaction with the peer over the adult. The aggressive maltreated children showed a clear preference for interaction with the peer over the adult. The aggressive maltreated children showed a clear preference for interaction with the adult. They also demonstrated a decrease of positive behavior and increase in negative behavior in response to the programmed initiations. Implications of these differential responses were discussed. 相似文献
