Few studies have examined social work students’ reflections on and experiences working with lesbian, gay, bisexual, queer, and questioning persons and addressing the intersection of race/ethnicity and sexuality within practice. This study explored current master’s of social work student (n = 11) and recent graduate (n = 7) reflections on conducting an objective structured clinical practice interaction with an African Canadian youth coming out as a lesbian. Narrative thematic analyses of reflective dialogues highlighted a variation of competence in gay affirmative practice across attitudes (managing personal reactions), knowledge (addressing diversity; terminology and information), and skills (readiness; challenging heterosexism). Curriculum development and agency-based training is recommended to address gaps in knowledge and competence regarding gay affirmative approaches.  相似文献

This article examines dependency on cross-border labor and marriage along the international frontier in the Kelabit Highlands of Sarawak, Malaysia (Borneo) and some local efforts to restrict outsiders. The international border in this remote region of Borneo is highly permeable, and border-crossing activities, including seasonal migrant wage labor and cross-border marriage, are crucial both to the local political economy and to the reproduction of the Kelabit family and farm. This article explores the unique position of the Kelabit as they attempt to appropriate aspects of state power or use the rhetoric of state power in their efforts to maintain a status quo with regard to neighboring, and closely related, migrant workers from across the border.  相似文献

Research findings on comorbidity and pathological gambling are non–existent in Chinese communities. The objectives of this study were to: (a) determine the prevalence of comorbid mood and adjustment disorders among pathological gamblers seeking treatment in Hong Kong; (b) compare demographic profiles and clinical features in pathological gamblers with and without comorbid mood and adjustment disorders; and (c) explore the association and temporal relationship between pathological gambling and comorbid mood and adjustment disorders. Assessment instruments included demographic data, BSI, SCID-I, ASI and LIFE-RIFT. Results showed that about two-thirds (63.7%; n = 128) of 201 participants reported lifetime comorbid psychiatric disorders. Most common comorbid disorders were mood disorders (29.4%; n = 59) and adjustment disorders (20.9%; n = 42). Pathological gamblers with comorbid mood or adjustment disorders showed more severe levels of psychopathology, impairment in psychosocial functioning and gambling problems. This study is important because it is the first scientific comorbidity study among pathological gamblers in a Chinese context.  相似文献

The problem of computing the strength and performing optimal reinforcement for an edge-weighted graph G(V, E, w) is well-studied. In this paper, we present fast (sequential linear time and parallel logarithmic time) on-line algorithms for optimally reinforcing the graph when the reinforcement material is available continuously on-line. These are the first on-line algorithms for this problem. We invest O(|V|3|E|log|V|) time (equivalent to (|V|) invocations of the fastest known algorithms for optimal reinforcement) in preprocessing the graph before the start of our algorithms. It is shown that the output of our on-line algorithms is as good as that of the off-line algorithms. Thus our algorithms are better than the fastest off-line algorithms in situations when a sequence of more than (|V|) reinforcement problems need to be solved. The key idea is to make use of ideas underlying the theory of Principal Partition of a Graph. Our ideas are easily generalized to the general setting of polymatroid functions. We also present a new efficient algorithm for computation of the Principal Sequence of a graph.  相似文献

This paper elaborates on some issues discussed by Moskowitz, who presented evidence that linear multiple regression models, estimated from decisions made by individuals, often outperform the individuals themselves. In discussing his results, Moskowitz (1) suggested that inconsistency in information utilization by individuals may account for the relative superiority of regression models, and (2) expressed concern over the robustness of linear regression models to changes in (a) information environments, (b) weighting parameters, and (c) functional form of the model. This paper discusses reasons (in addition to inconsistency) for the relative superiority of model over man, and it summarizes recent research in psychology concerning the robustness of linear regression models (and linear models in general). This paper is supportive, rather than critical, of Moskowitz's research.  相似文献

A class of decisions, asset mix decisions made by pension fund managers, which exhibit characteristics of both programmed and strategic choices is examined in this paper. The decisions are classified using the scheme developed by Mintzberg et al., (1976) to highlight the circumstances under which strategic decisions may be programmed. The types of strategic decisions which lend themselves to programming are considered. The advantages and disadvantages of programming strategic decisions are also discussed.  相似文献

Findings from studies that have investigated the relationship between task-relevant ability and turnover have been inconsistent. A process model is presented that suggests that ability may be related to turnover through the individual's perception of both the ease and desirability of movement. The potential effect of ability on the turnover process and its practical and theoretical implications are discussed.  相似文献

思维运动主体不是人脑,而是从事社会实践的人。近代形而上学唯物主义把人脑看作是思维运动的主体,虽然肯定了思维运动主体的物质性,但却忽视了它的社会实践性。马克思主义哲学从实践出发理解现存世界和人的思维,把实践看作“人的思维的最本质和最切近的基础”,将从事社会实践活动的人确立为思维运动的主体,从而在思维运动主体上实现了物质性、实践性和社会性三者的有机统一。  相似文献

We consider a continuous-time model for the evolution of social networks. A social network is here conceived as a (di-) graph on a set of vertices, representing actors, and the changes of interest are creation and disappearance over time of (arcs) edges in the graph. Hence we model a collection of random edge indicators that are not, in general, independent. We explicitly model the interdependencies between edge indicators that arise from interaction between social entities. A Markov chain is defined in terms of an embedded chain with holding times and transition probabilities. Data are observed at fixed points in time and hence we are not able to observe the embedded chain directly. Introducing a prior distribution for the parameters we may implement an MCMC algorithm for exploring the posterior distribution of the parameters by simulating the evolution of the embedded process between observations.  相似文献
