美国环保协会的故事开始于50多年前一场关于保护鸬鹚,一种可爱的鸟类的运动。上世纪60年代,美国长岛的科学家惊讶地发现当地鸬鹚幼鸟的数量由于不知名的原因,急剧下滑至正常数量的七分之一。与此同时,秃头鹰、游隼等其他猛禽的数量也出现了同样惊人的跌幅。其中一些科学家通过科学研究追踪问题的根源,发现喷洒杀虫剂DDT(又称“滴滴涕”)是造成这一现象的罪魁祸首。在通过科学的指证赢得了在美国全面禁止DDT使用的官司之后,为了进一步保护人类赖以生存的自然环境,这些科学家成立了美国环保协会。  相似文献

Social workers have made a significant contribution to the developmentand delivery of palliative care. Both palliative care and socialwork are rapidly evolving but, given their changing contextsand increasing workloads, can they sustain compatibility? Advancesin treatment of life-threatening illness mean that people livelonger in a period of palliative care. Social work has undergoneradical change in the wake of the 1990 NHS and Community CareAct and subsequent local-authority modernizations, with socialworkers now given the role of care managers, rather than themore traditional ‘casework’ or therapeutic role.This paper aims to explore the current and potential role ofthe social worker in palliative care for people with cancerand other prolonged life-threatening illness. It draws uponevidence from a prospective qualitative, patient-centred researchstudy, which detailed the experiences of forty people with lungcancer and advanced cardiac failure, and their personal andprofessional carers (Murray et al., 2002). A total of two hundredand nineteen qualitative interviews were carried out. We found that social workers were conspicuous by their absencefrom the lives of these forty vulnerable adults, who were livingand dying in the community with many unmet needs which, potentially,could be met by social-work input. The study highlights sixareas of concern in which social-work assessment and interventioncould have impacted on dying patients’ quality of lifeand that of their carers: loss and dependency, family-centredissues, carers’ needs, practical tasks, emotional andspiritual struggles, and finally, support needs of staff. Theseareas are outlined to explore the territory which a social workermight inhabit if resources and policies permitted.  相似文献

The interaction of geography and world-systems theory has created two groups of work. The first body of work uses world-systems theory as its theoretical framework with minor levels of critique or change. The second body of work attempts to inform world- systems theory by explicitly including a geographical perspective. Human geographers attracted to world-systems theory provide a perspective that highlights the role of agency in what is widely perceived to be a rigid structuralist approach. Key geographical concepts of region and place are viewed as social constructs created within an overarching context of structural imperatives. By conceptualizing places, states, and the macroregions of core, semiperiphery, and periphery as geographical scales, the role of agency in creating and maintaining the important structures and institutions of the capitalist world-economy, such as hegemony, is illustrated. The geographer's interest in the creation of geographical scales results in analysis of the dynamism of the contemporary world-system.  相似文献

This study examined the extent to which supervisory phone-ins were related to change in both immediate therapist behaviors and subsequent change in resistant behaviors of client family members. Of specific interest was whether the congruence of supervisor and therapist behaviors (referred to as isomorphism by some family therapy authors) would be related to immediate change in client resistance. The quality of supervisor's Support and Teach behaviors was foundj to be significantly related to the change in the quality of the threrapists' Support and Teach behaviors. Moreover, in instances where both supervisors and their supervises demonstrated effective Support and Teach behaviors, clients generally tended to either remain cooperative or become cooperative more frequently than when both effective supervisor and supervisee behaviors where not present.  相似文献

The mere-exposure effect is the formation of a positive affective reaction (PAR) to repeated or single exposure to a stimulus, even in the absence of awareness. The mere-exposure effect indicates that communication effects go beyond “explicit memory”, measured with the traditional measures of (aided) recall and recognition. “Implicit memory” indicates latent communication effects, e.g., liking, for persons exposed to particular stimuli. The mere-exposure effect in the absence of awareness represents implicit memory. In this study, the mere-exposure effect is observed by using a new type of divided-attention method with Chinese participants responding to Chinese characters. The prediction by the two-factor model of mere-exposure effect is confirmed. Recognition (“explicit memory”) may inhibit the mere-exposure effect. Recognition memory is a dual process with two aspects: recollection and familiarity. Employing the process dissociation procedure (PDP) (Jacoby, L.L., 1991. Journal of Memory and Language 30, 513–541), it is found that familiarity of above-chance recognition is greater than that of chance recognition. It is the high level of familiarity and not recollection of abovechance recognition that inhibits the mere-exposure effect. The implications of these findings are that a high level of familiarity inhibits the primary affective reaction and “replaces” this reaction with a more conscious and cognitive evaluation. With the two-factor model, with wear-in (habituation) and wear-out (satiation) factors, the optimal level of exposure may be determined in order to increase the affective reaction. The study shows the robustness of the mere-exposure effect, also for familiar stimuli.  相似文献

Increasingly complicated tools known as financial derivatives have been introduced in recent times to manage the market risk arising from floating exchange rates. The rapid development of the derivatives markets has in turn introduced new risks into the business of finance - witness the highly-publicised trading losses at Metallgesellschaft and Procter and Gamble. A principal method for measuring and reporting market risk in the portfolios of banks and their clients is ‘value at risk’ (VaR).Fred Stambaugh explains the concept of ‘value at risk’ and describes three principal approaches to calculating it - correlation matrix, historical simulation and Monte Carlo simulation; they are alternatives, not competitors. As well as setting out their uses, he considers those situations that go beyond ‘value at risk’, i.e. dire events that lie beyond the confidence level of VaR. Techniques for portfolio stress testing are discussed.  相似文献

Military courts have had to face the issue of compulsive gambling in criminal court-martial proceedings. The military recently switched from the liberal ALI definition of insanity to the much more stringent standards of the federal Insanity Defense Reform Act. However, military courts have not even allowed in expert testimony, holding the relevance of compulsive gambling has not been generally accepted in the scientific community. The rules involving extenuation or mitigation in sentencing allow much more leeway. Although compulsive gambling cannot be used as the basis for a defense of insanity in military courts, defense lawyers will continue to raise the issue in attempting to obtain lesser punishments for their military clients.B.S.
