Conclusion In the event of death, society has in place a wide range of rituals and supports designed to help mourners deal with their grief. It may be that assigning blame and seeking legal recourse has become a significant ritual for those who have sustained other types of losses and, in some situations, loss through death as well. However, unlike societal death rituals, which guide the mourners, no guidelines exist to help negotiators address the impact of grief on their clients. Thus, in this article, insights gleaned from studies of grief, loss, and separation have been examined in an effort to develop an awareness of the impact of grief reactions on the parties to negotiation.Grief reactions—ranging from denial, bargaining, anger, depression, and guilt to acceptance—serve a useful purpose for those who have sustained grievous losses. Consequently, a better understanding of grief factors may be advantageous to negotiators and, more importantly, to their clients. Such considerations may help challenge perceptions of other parties that may otherwise be prejudicial to one's client (as in the Lindy Chamberlain case) and assist negotiators in trying to anticipate, and thus protect their clients from, grief-related reactions of other parties. In the large number of cases where negotiation and settlement discussions are not only critical but also decisive, grief theory may provide negotiators with better insight into client, and other party, interests and may help them to formulate advice and intervention strategies that take the impact of various grief reactions into account. Nancy Lewis Buck is an attorney and social worker, currently completing a doctoral dissertation at Yale Law School. Her mailing address is 9 Surrey St., Cambridge, Mass. 02138.  相似文献

This article summarizes some of the literature reviewed by the Girls Study Group, which is a federally funded project aimed at assessing the causes of girls’ delinquency as well as evaluating programs to address it. The literature reveals that a number of factors such as family dysfunction, involvement with antisocial peers, and living in disadvantaged neighborhoods are correlated with delinquency for both boys and girls. Some factors, however, are gender sensitive, meaning that either girls are more exposed to a given risk factor than boys or react somewhat differently to a given risk factor. Girls have higher rates of exposure to sexual assault, which is associated with delinquency and, although more research is needed, they are more affected by the impacts of early puberty, when it is coupled with harsh parenting and disadvantaged neighborhoods. This article discusses some implications of the research on correlates of delinquency for programming for girls and makes recommendations for program selection.  相似文献

The American Law Institute proposes that in contested physical custody cases the court should allocate to each parent a proportion of the child's time that approximates the proportion of time each has spent performing caretaking functions in the past. Examined through the lens of child development research, the approximation rule is unlikely to improve on the best interests standard. It is difficult to apply; is perceived as gender‐biased; creates a new focus for disputing parents; renders a poor estimate of parents’ contributions to their child's best interests; overlooks parents’ intangible, yet significant, contributions to their child's well‐being; and miscalculates the essence of how a child experiences the family. A preferable alternative is a better defined, contemporary best interests standard that accommodates new knowledge and reforms that encourage nonadversarial, individualized resolutions of custody disputes.  相似文献

A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning.  相似文献

Archibald T. Strong, born in Melbourne, was the son of an Australian scholar who went to an academic post at Liverpool. The younger Strong received his secondary and tertiary education in England. There, he became proficient in modern European languages and literature. He initially planned a career in the law, but for health reasons returned to Australia to the Department of English at the University of Melbourne. Prior to the First World War, Strong became prominent in Melbourne literary circles and also a prolific commentator on world affairs. As an early member of the Round Table group in Australia, Strong assessed Imperial Germany as posing an existential threat to the British Empire and hence to Australia's security. The nation's future, he believed, lay in unwavering defence of the Empire. Strong evinced a distinct impatience with fellow citizens, especially on the socialist left, who failed, in his view, to understand the realities of Australia's position in the world and what was at stake in the Great War.  相似文献

Decomposition studies were conducted using two carcasses of domestic pigs, Sus scrofa L., 8.4 kg and 15.1 kg in weight, to determine the effects of carcass size on the rate of decomposition, composition of the arthropod fauna, and succession patterns. A total of 46 arthropod taxa were recovered during this study. No size-related differences were observed between carcasses with respect to composition of the arthropod fauna or patterns of succession. A greater number of arthropods were observed attracted to the 15.1-kg carcass, and the rate of decomposition observed was more rapid for the 15.1-kg carcass than for the 8.4-kg carcass. Internal temperatures of the 8.4-kg carcass were more directly related to external ambient temperatures during the fresh and bloated stages of decomposition. During the decay stage, both carcasses generated internal temperatures significantly above ambient temperatures. Following this stage, internal temperatures fell to approximate ambient temperatures during the postdecay and remains stages.  相似文献
