The current review examines conceptual and methodological issues related to the use of dialectical behavior therapy for adolescents (DBT-A) in treating youth who engage in deliberate self-harm. A comprehensive review of the literature identified six studies appropriate for the review. Results indicated several inconsistencies and limitations across studies including the mixing of various forms of self-harm; variations in diagnostic inclusion/exclusion criteria, insufficient use of standardized self-harm outcome measures, variable lengths and intensity of provided treatment, and inadequate attention paid to DBT adherence. Each of these areas is reviewed along with a discussion of ways to improve the quality of future research. 相似文献

As the social context in which gay men live changes due to greater visibility, greater acceptance, and easier access to gay subculture, gay males may self-identify and take part in gay social activities at earlier ages than in the past. This study examined whether developmental milestones associated with sexual orientation for gay men have changed over the past several decades. A large and diverse sample of 2,402 gay men who responded to a 1994 survey published in a national magazine provided retrospective information on the age at which they reached individual psychological, social, and sexual behavior developmental milestones. We found evidence that individual psychological and sexual behavior milestones (e.g., awareness of attraction to males, having an orgasm with other male) are slowly moving toward earlier chronological ages (by 1 year of age every 8-25 years, p < 0.05), whereas social milestones (e.g., coming out) are moving more rapidly in a similar direction (by 1 year of age every 2-5 years, p < 0.001). The authors perform an innovative sensitivity test to demonstrate the persistence of the finding after correcting for the bias attributable to underrepresentation of those who have not yet self-identified as gay in such samples. 相似文献

The increasing popularity of Interpretative Phenomenological Analysis (IPA) in social research brings an increasing criticism about its validity, robustness and, more recently, its lack of expressive features. Recently, the novel arts-based research approach called body-mapping was recognized as enhancing social science research in creative and nuanced ways. Body-mapping allows for unique insights into participants’ lived experiences, the meaning thereof, and into how meaning is impacted by their socio-cultural contexts. This article provides new understandings about the potential use of body-mapping as part of an IPA framework by drawing upon existing literature to critically discuss their philosophical and methodological congruence. The following discussion demonstrates how particular strengths of body-mapping align with weaknesses of IPA and that, when merged, they may be especially useful for research with vulnerable and hard-to-reach populations. Limitations of this discussion and implications for future research are provided. 相似文献

This paper presents point and interval estimators of both long-run and single-period target quantities in a simple cost-volume-profit (C-V-P) model. This model is a stochastic version of the “accountant's break-even chart” where the major component is a semivariable cost function. Although these features suggest obvious possibilities for practical application, a major purpose of this paper is to examine the statistical properties of target quantity estimators in C-V-P analysis. It is shown that point estimators of target quantity are biased and possess no moments of positive order, but are consistent. These properties are also shared by previous break-even models, even when all parameters are assumed known with certainty. After a test for positive variable margins, Fieller's [6] method is used to obtain interval estimators of relevant target quantities. This procedure therefore minimizes possible ambiguities in stochastic break-even analysis (noted by Ekern [3]). 相似文献

In 1980 the Joint Economic Committee completed the Special Study on Economic Change. This 20 volume, 3-year project, was premised on the fact that: ‘fundamental economic, social, political, international and technical conditions have changed, and are still changing markedly’. This suggests that conventional wisdom and established economic tools may not be equal to meeting the challenge of making sound policies in the economic sphere. The so-called laws of economics have not been repealed, but all guiding principles presuppose a certain environment of conditions, customs and practices—and when these change, the implementation of new policies and the modes of adjustment have to change also. This paper examines the problem of devising policy instruments for economic management, identifying the facts of the changing economic environment and the main difficulties facing world economic development. 相似文献
