Abstract

Using Habermas' (1971) Grand Theory and Schaefer's (1979) notion of Theory as Fiction, two major philosophical assumptions that undergird the literature, practice and teaching of social work are reviewed. Empiricism dominates social work theory and aims at technical control. Existentialism has been an important but marginal voice and attempts to explain subjective meaning. Two newer theoretical positions also are introduced: Critical theory, which considers humanity's ability to reflect on history to be an agent of societal change; and deconstruction, which questions the validity of any structure. The article concludes with a consideration of the implications of using each position as a context for teaching.  相似文献

This commentary on Avgi Saketopoulou’s article develops her startling claim that sexual perversion may be psychically useful. It does so by elaborating the twin concepts of ébranlement (shattering) and enigmatic signifier that Saketopoulou derives from the metapsychology of Jean Laplanche in order to consider an analogy between the work of perversion and the work of psychoanalysis. If sadomasochism holds a psychically transformative potential comparable to that of clinical analysis, then on what grounds should one practice be prioritized over the other?  相似文献

Research has suggested women’s sexual response cycle may vary more than previously thought. We asked 769 sexually active women between the ages of 18–70 to report on their sexual desire and arousal patterns during their last sexual experience. Using a latent class mixture model from retrospective sexual response data, we found six classes of desire and arousal patterns (Low, Middle Steady, High Fluctuation, Low Fluctuation, Upper Steady, High). We examined how these patterns were related to demographics, outcomes during the sexual experience, and outcomes for the global relationship. The Low sexual response class (8% of women) was significantly different from other classes in duration of the sexual experience, orgasms, and overall satisfaction with the sexual experience. Most sexual response patterns were associated with healthy relational and sexual outcomes. All classes except for the Low arousal and desire class showed associations with a neutral or positive sexual satisfaction evaluation. The non-problematic variation of women’s sexual experience is an important concept to consider as it impacts determinations of dysfunction and women’s self-evaluations. Not all women need to experience high levels of arousal throughout the sexual experience or to have desire at the outset in order to have positive sexual experiences and sexual outcomes.  相似文献

Currently there appears to be a spate of world, national and local disasters. Always there is concern, not only about how to manage the immediate emergency, but how to facilitate the long-term recovery period. This paper presents a six-months perspective of a particular disaster and recovery period, based on the experiences of a recovery worker. It emphasises the importance of routine training for workers in organisations who may be called upon in a disaster. It notes that because of the unique situation in every disaster, decision making on recovery structures and processes needs to remain invested in the local community, with assistance from external resources. It makes other suggestions for consideration in the continuing building of recovery theory. Finally, it underlines the importance of the social work role in most aspects of disaster recovery work, and the need to prepare not only undergraduates, but professional workers, for this role.  相似文献

Abstract

Objective: The purpose of this study was to employ a multivariate approach to examine the correlates of self-rated health in a college sample of women, with particular emphasis on sexual assault history and related mental health outcomes. Participants: A national sample of 2,000 female college students participated in a structured phone interview between January and June 2006. Methods: Interview modules assessed demographics, posttraumatic stress disorder, major depressive episode, substance use, rape experiences, and physical health. Results: Logistic regression analyses showed that poor self-rated health was associated with low income (odds ratio [OR] = 2.70), lifetime posttraumatic stress disorder (OR = 2.47), lifetime major depressive episode (OR = 2.56), past year illicit drug use (OR = 2.48), and multiple rape history (OR = 2.25). Conclusions: These findings highlight the need for university mental health and medical service providers to assess for rape history, and to diagnose and treat related psychiatric problems in order to reduce physical morbidity.  相似文献

In many applications, the cumulative distribution function (cdf) \(F_{Q_N}\) of a positively weighted sum of N i.i.d. chi-squared random variables \(Q_N\) is required. Although there is no known closed-form solution for \(F_{Q_N}\), there are many good approximations. When computational efficiency is not an issue, Imhof’s method provides a good solution. However, when both the accuracy of the approximation and the speed of its computation are a concern, there is no clear preferred choice. Previous comparisons between approximate methods could be considered insufficient. Furthermore, in streaming data applications where the computation needs to be both sequential and efficient, only a few of the available methods may be suitable. Streaming data problems are becoming ubiquitous and provide the motivation for this paper. We develop a framework to enable a much more extensive comparison between approximate methods for computing the cdf of weighted sums of an arbitrary random variable. Utilising this framework, a new and comprehensive analysis of four efficient approximate methods for computing \(F_{Q_N}\) is performed. This analysis procedure is much more thorough and statistically valid than previous approaches described in the literature. A surprising result of this analysis is that the accuracy of these approximate methods increases with N.  相似文献

We examine the possibilities of premature and postponed replacement in a deterministic infinite horizon model when there is technological progress. Both revenue and operating cost deteriorate with age, but at different rates. The optimal deterministic replacement time is an implicit solution from the timing boundary obtained for the equivalent real option model using a dynamic programming framework, and then by setting the underlying volatilities equal to zero. A step change improvement characterizing technological progress in the initial operating cost level for the successor occurring during the economic lifetime of the incumbent justifies premature replacement, compared to the traditional present value approach. This finding can be extended to step change improvements in the initial revenue level for the successor and for the re-investment cost. In contrast, if the technological progress can be characterized by a constant declining rate for the initial operating cost level for the successor, then the replacement is postponed for certain parameter values. This finding can be extended to different assumed improvement rates in the initial revenue level for the successor and for the re-investment cost.  相似文献

Substantial youth minimum wage changes in New Zealand between 2000 and 2007 raised teenage average wages by 5–10 per cent relative to those for adults. We use Statistics New Zealand's Linked Employer–Employee Database (LEED) to examine whether firms' teenage labour demand responses to these changes are greater for firms with higher teenage‐employment share. We find evidence that high teen‐employers reduced their teen employment relative to other firms and had lower survival rates over the period. However, firms that entered the main teen‐employment industries had higher teen‐employment shares than continuing firms. The results are consistent with endogenous technology adoption in response to non‐marginal changes in relative wages.  相似文献

The Lilliefors test, which was developed by Lilliefors (1967), is a well-known test for univariate normality when population parameters are unknown. The main assumption for implementing the test is the independent-data assumption. This paper demonstrates the robustness of the Lilliefors test against equicorrelated observations. More specifically, we show that the null distribution of the Lilliefors test statistic is invariant under the alternate assumption that the observations are equicorrelated.  相似文献
