Studies of resilient youth have documented the helpful influence of religion in their lives. In the absence of positive influences among high-risk youth, religion and religious organizations in particular often serve to promote prosocial outcomes. This study, on the other hand, investigates whether religion and religious change are comparably effective influences in reducing the vulnerability of low-risk youth to drinking, drug use, delinquency, problems in school, and poor grades. Using data from the National Longitudinal Study of Adolescent Health, this study identified at least one influential aspect of religion that serves as a direct protective factor across each mode of vulnerability, and also documented indirect pathways of religious influence. We discuss the findings and consider the variable influence of religion on youth.  相似文献

Curve estimates and surface estimates often contain features such as inclines, bumps or ridges which may signify an underlying structural mechanism. However, spurious features are also a common occurrence and it is important to identify those features that are statistically significant. A method has been developed recently for recognising feature significance based on the derivatives of the function estimate. It requires simultaneous confidence intervals and tests, which in turn require quantiles for the maximal deviation statistics. This paper reviews and compares various approximations to these quantiles. Applying upcrossing‐probability theory to this problem yields better quantile approximations than the use of an independent blocks method.  相似文献

This paper concerns designed experiments involving observations of orientations following the models of Prentice (1989) and Rivest &Chang (2006). The authors state minimal conditions on the designs for consistent least squares estimation of the matrix parameters in these models. The conditions are expressed in terms of the axes and rotation angles of the design orientations. The authors show that designs satisfying U1 + … + Un = 0 are optimal in the sense of minimizing the estimation error average angular distance. The authors give constructions of optimal n‐point designs when n ≥ 4 and they compare the performance of several designs through approximations and simulation.  相似文献

The purpose of this study is to quantify 86 contingent variables and modify the construct of the contingency theory. A nationwide survey among public relations practitioners first enabled quantitative analysis of the 86 contingent variables affecting public relations practice, divided into 12 factors on two dimensions. This test gave parsimony to the matrix of 86 contingent variables initially offered in the matrix, provided validity to the contingency theory, and suggested its theoretical evolution measured against Occam's Razor, which holds that the simplest explanation is generally the most precise and thus the best approach to follow in building theories.  相似文献

Economic Stress in Lives: Developmental Perspectives   总被引:1,自引:0,他引:1  
A major task for research on the social costs of economic stress is to trace how macrosocial changes affect increasingly smaller social units and ultimately those microsocial phenomena that directly influence children in their families. In this paper, we specify linkages between macroeconomic change and children's development by tracing deprivational effects through family adaptations in the household economy and in personal relationships. Our findings from research on children and families of the Great Depression are discussed in relation to an interactional model of the process by which families adapt to stressful times.  相似文献

Sex-related distress is integral to the diagnosis of hypoactive sexual desire disorder (HSDD). This article describes the results of three prospective, non-treatment validation studies (two North American and one European), each testing over 200 participants with HSDD, other types of female sexual dysfunction (FSD), or no FSD in which the 12-item Female Sexual Distress Scale© (FSDS©), the 13-item FSDS–Revised©(FSDS–R©), and a single question asked using a daily electronic diary (the eDiary For HSDD Trials©; eDiary) were used to measure sex-related distress. FSDS results with 30- and seven-day recall were equivalent. The results observed with FSDS–R Item 13 (a single question assessing concern due to low sexual desire) were comparable to the FSDS. Mean eDiary monthly distress scores were closer to the minimum possible score (equivalent to “a little bit” of distress) and were about twice as variable as FSDS or FSDS–R Item 13 scores in participants with HSDD. All three measures confirmed that there is more distress in women with HSDD compared to women with no sexual dysfunction at all time points, demonstrating discriminant validity.  相似文献

ABSTRACT

Social work research and literature in the area of supervision tends to focus on the supervision of field education students. Less attention is given to the supervision of social work practitioners and there is almost no information that examines how social workers become supervisors. This exploratory study interviewed 27 practicing social work supervisors across different fields of social work practice in Western Canada. The participants included 15 supervisors with a graduate degree and 12 supervisors with an undergraduate degree. The supervisors completed a brief questionnaire that was followed by a structured interview. Supervisors were asked how they came to be social work supervisors. Thematic analysis of the supervisors’ responses revealed three pathways to supervision: task exposure, supervision by happen chance, and deliberate decision. The responses suggested that additional focus on supervision might be included in undergraduate education and that universities, professional associations, and employers pay more attention to succession planning.  相似文献

In order for empirical testing to be performed systematically on family therapy theories, appropriate testing instruments must be developed and validated. The purpose of this study was to develep a reliable and valid scale for measuring the related constructs of relational ethics as described in contextual family therapy (Boszormenyi-Nagy & Krasner, 1986). Presented here is the five-stage procedure used in development in Relational Ethics Scale, data supporting the validity and reliability of the scale, and the final version of the instrument.  相似文献
