This paper investigates the phenomenon of three clients living in squalor, all of whom have severe and enduring mental health problems, and are on the caseload of a mental health social work team. By thinking about the clients both individually and as a group, within a psychoanalytic framework, it attempts to understand their squalor in a new way, with particular regard to the transference and countertransference experienced by the practitioner. By making use of social work literature as well as that concerning organisations and community care, it also discusses the impact these clients make on the wider community around them, and examines some of the dilemmas faced by the practitioner. The implications for social work are serious and far-reaching and these are discussed with regard to long-term intervention as well as professional and personal scrutiny. 相似文献

This paper studies an M/G/1 clearing queueing system with setup time and multiple vacations, in which all present customers in the system are served simultaneously and breakdowns may occur in busy or setup period. We investigate the stationary distribution of system size and the Laplace–Stieltjes transform of sojourn time. In addition, various performance measures are discussed, such as the mean system size at arbitrary time and the mean length of a vacation circle. Moreover, a cost analysis is carried out for this queueing system. Numerical results are presented to study the sensitivity of the system parameters on the expected cost function and system performances. 相似文献

国际组织和成员国的法律责任归属问题一直以来都是国际法争论的话题。政府间国际组织作为一类国际法主体,应独立承担法律责任。但在实践中,成员国在执行国际组织决议的过程中往往滥用国际组织法律人格,其行为不仅是国际组织法律人格的体现,还代表了自己的意志,造成法律责任归属不明。以此种争议情形为研究对象,结合1999年的使用武力合法性案,2007年欧洲人权法院的拜拉米案和萨拉马提(Behrami/Saramati)案、阿尔吉达(Al-Jedda)案以及2014年海牙法院关于斯雷布雷尼察(Srebrenica)诉荷兰案的相关判决,借鉴国外学者近几年的相关研究,认为应当坚持国际组织和成员国法律责任的多重归属。围绕责任多重归属原则的确立过程,通过对2011年《国际组织责任条款草案》相关条文的分析,明确了行为归属与责任归属的关系:只有确定行为归属之后,才能确定责任归属;为了最终确定责任的多重归属,提出以有效控制为标准认定行为归属,并明确这种有效控制是对具体行为的事实控制。 相似文献

利用单期静态博弈分析法、有限期动态博弈分析法和无限期动态博弈分析法对成品油定价机制中寡头厂商的合谋行为进行了分析。研究发现:两家寡头厂商在合谋条件下的收益均高于双方各自独立定产条件下的收益,因此,双方存在进行价格合谋的利益激励。基于此,我国成品油价格形成机制的改革可以考虑采用有限规制等手段。 相似文献

In this paper, we investigate the complete moment convergence and Lr convergence for maximal partial sums of asymptotically almost negatively associated random variables under some general conditions. The results obtained in the paper generalize some corresponding ones for negatively associated random variables. 相似文献

一个地区的旅游业发展与该地的人文、地理、环境等有很大联系。近年来,随着长治旅游业的不断发展,上党神话作为长治地区特有的人文内涵与长治旅游业之间逐渐形成了相互影响、相互促进、相互合作和相互依赖的共生关系。上党神话在长治旅游业的旅游景区方面赋予了神秘的色彩,在旅游产品方面丰富了本地旅游产品的内涵,在旅游需求方面扩展了长治旅游消费市场;同时,长治旅游业对上党神话的普及、发展及延伸也发挥了补充作用。 相似文献

Motivated by several practical issues, we consider the problem of estimating the mean of a p-variate population (not necessarily normal) with unknown finite covariance. A quadratic loss function is used. We give a number of estimators (for the mean) with their loss functions admitting expansions to the order of p ?1/2 as p→∞. These estimators contain Stein's [Inadmissibility of the usual estimator for the mean of a multivariate normal population, in Proceedings of the Third Berkeley Symposium in Mathematical Statistics and Probability, Vol. 1, J. Neyman, ed., University of California Press, Berkeley, 1956, pp. 197–206] estimate as a particular case and also contain ‘multiple shrinkage’ estimates improving on Stein's estimate. Finally, we perform a simulation study to compare the different estimates. 相似文献

This study examined whether being in a romantic relationship is associated with undergraduates’ alcohol use and negative consequences of drinking. Alcohol use was operationalized to include amount and frequency of drinking, binge drinking, and drunkenness. Negative consequences included: having a hangover, missing a class, getting behind in school work, doing something that was later regretted, forgetting where the student was or what they did, having unplanned sex, and getting hurt or injured. Data came from an online survey distributed to Midwestern undergraduate students (N = 572), with analyses conducted separately for men and women. Results indicated that being in a committed relationship generally served as a protective factor against drunkenness, but did not reduce frequency of drinking or binge drinking. Whereas romantically committed men were only less likely to report doing something that was later regretted, women in romantic relationships were less likely to experience all negative consequences of drinking considered here. 相似文献

The current study used dyadic data to investigate the impact of relationship type and social support on the retrospective accounts of commitment trajectories of romantic relationships. Past research suggests that social support is a positive contributor to relationship stability and commitment, which may be especially true for partners in interracial relationships who face broader societal opposition than intraracial couples. Using multilevel modeling, we investigated the effects of sex, relationship type, and social support on reports of commitment. Results showed differences in trajectories of commitment based on couple type (interracial vs. intraracial) for both men and women. Social support was found to have an especially strong impact for women in interracial relationships compared with women in intraracial relationships, but there was no differential impact among men. 相似文献
