Divorce, although a statistical norm, is a developmental trauma to the children involved. This article looks at the two-camp emotional environment of a divorcing family and its effect on the formation of a child's identity. By examining developmental ages, chosen according to divorce research, the author attempts to show how the interspouse emotional cathexes negatively affect a child's sense of self in ways specific to the child's age at the divorce.  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

Jorge Sanjinés' 1960s films Revolución and Ukamau challenge the class and ethnic hierarchies of Bolivian society by casting the proletarian and indigenous masses as revolutionary liberators. The new national imaginary they evoke is tightly bound to the experimental cinematic techniques they employ, since their rejection of rationalist, realist aesthetics signals a partial undermining of the linear time of the modern nation. Ukamau both recalls and resists previous Bolivian indigenismo, which sought to co‐opt the Indian into a national mestizo consciousness. Its exoticist portrayal of the Indian ultimately limits its political effectiveness, but textual and contextual analyses show subversive Indian agency leaking through.  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

The accountability of international development NGOs (INGOs) has attracted a great deal of interest from academics and development practitioners. INGO accountability falls into two categories: practical accountability (for the use of inputs, the way activities are performed, and outputs) and strategic accountability for INGOs' performance in relation to their mission. This article presents a conceptual framework for exploring INGO accountability. It is based on information collected through a literature review and semi-structured interviews with representatives from 20 UK-based INGOs. The research found that INGOs tend to use a number of quality-assurance mechanisms to achieve ‘practical’ accountability. However, it is suggested that this kind of accountability will not necessarily enable INGOs to achieve their missions to alleviate poverty and eliminate injustice. Furthermore, the predominant use of practical accountability has led to a number of gaps in INGO accountability. It is suggested that, like the term ‘participation’ before it, accountability has been co-opted for its instrumental benefits to INGO project performance and management. It is argued that if INGOs are to achieve their missions, this will require more ‘strategic’ forms of accountability, geared towards fundamentally changing those social, economic, and political structures that promote poverty.  相似文献
