Among older youth transitioning from the foster care system, this longitudinal study examined the association of religious and spiritual capital to substance use in the past year at age 19. Participants consisted of African American (N = 179) and White non‐Hispanic (N = 133) older youth in foster care. Drawing from social capital theory, it was posited that religious service attendance (a proxy for religious capital) and belief in a spiritual force (a proxy for spiritual capital) would be inversely associated with substance use. Multiple logistic regression results indicated support for the first and second hypothesis for White foster youth only. Among White foster youth, more frequent religious service attendance and greater belief in a spiritual force were associated with a lower likelihood of illegal substance and polysubstance use. No association between religious or spiritual capital and substance use was found among African American foster youth. The findings underscore the importance of conducting spiritual assessments to help ensure older foster youth who have strong religious or spiritual orientations are in environments where they are accommodated and supported. 相似文献

Corruption is a social ill that involves public officials’ misuse of entrusted power, which is a function of sociocultural factors. Rarely, however, do researchers view corruption as a leadership-related problem. In the current research, we conceptualize corruption as a leadership-related problem, and propose three broad leadership prototypes based on social value orientation theory and research. We seek to examine (1) how cultural endorsement of self-serving, prosocial, and individualistic leadership prototypes is related to corruption at the societal level and (2) how wealth moderates the relationship between cultural endorsement of self-serving leadership and corruption. Using archival data of 53 societies, we found that cultural endorsement of self-serving leadership was positively related to corruption, strengthened by wealth. Cultural endorsement of prosocial leadership and individualistic leadership, however, was not significantly related to corruption, and wealth did not moderate either of the relationships. The implications of these findings for theory and future research are discussed. 相似文献

This article employs the process of critical reflection to uncover and challenge the hegemonic assumptions of evidence-based practice (EBP). The critical reflection process results in a re-conceptualisation of best practices that, while still honouring empirical research, is less hierarchical and more inclusive of a broad spectrum of interests than traditional EBP. Multidimensional Evidence-Based Practice (MEBP) validates consumer wisdom, professional experience, and qualitative research as equal partners to quantitative research in determining current state-of-the art best practices. Furthermore, MEBP incorporates a value-critical analysis of those best practices that can lead to improvements and innovations, so that ‘best practices’ becomes a dynamic rather than a static construct. 相似文献

Estimation of benchmark doses (BMDs) in quantitative risk assessment traditionally is based upon parametric dose‐response modeling. It is a well‐known concern, however, that if the chosen parametric model is uncertain and/or misspecified, inaccurate and possibly unsafe low‐dose inferences can result. We describe a nonparametric approach for estimating BMDs with quantal‐response data based on an isotonic regression method, and also study use of corresponding, nonparametric, bootstrap‐based confidence limits for the BMD. We explore the confidence limits’ small‐sample properties via a simulation study, and illustrate the calculations with an example from cancer risk assessment. It is seen that this nonparametric approach can provide a useful alternative for BMD estimation when faced with the problem of parametric model uncertainty. 相似文献

This article utilises historical information to throw light on the forces shaping British aid policies towards Africa. It outlines key long‐term policy developments, summarises the influences shaping these policies and comments on the present juncture of UK policies. It shows that, while there have been many influences, governments have enjoyed considerable policy autonomy, being largely unconstrained in pursuing their preferences in a top‐down manner. This autonomy has mainly been used for the pursuit of long‐term development, as against the promotion of the UK's national interest. The present thrust of UK policies to achieve massive increases in aid to Africa is a prime example of this policy autonomy. 相似文献

This article deals with the issue of using a suitable pseudo-likelihood, instead of an integrated likelihood, when performing Bayesian inference about a scalar parameter of interest in the presence of nuisance parameters. The proposed approach has the advantages of avoiding the elicitation on the nuisance parameters and the computation of multidimensional integrals. Moreover, it is particularly useful when it is difficult, or even impractical, to write the full likelihood function. We focus on Bayesian inference about a scalar regression coefficient in various regression models. First, in the context of non-normal regression-scale models, we give a theroetical result showing that there is no loss of information about the parameter of interest when using a posterior distribution derived from a pseudo-likelihood instead of the correct posterior distribution. Second, we present non trivial applications with high-dimensional, or even infinite-dimensional, nuisance parameters in the context of nonlinear normal heteroscedastic regression models, and of models for binary outcomes and count data, accounting also for possibile overdispersion. In all these situtations, we show that non Bayesian methods for eliminating nuisance parameters can be usefully incorporated into a one-parameter Bayesian analysis. 相似文献

This article describes a group‐based intervention for adolescents specifically designed to improve motivation to change sexually abusive behaviour. The intervention is intended to be used as a single module within a comprehensive treatment programme based on cognitive behavioural and relapse prevention principles. It utilizes the Prochaska and DiClemente ( 1983 , 1986 ) model of the stages of change and Morrison's ( 1998 ) seven steps in contemplating change. We have combined these two models to produce ‘11 Steps of Motivation and Action in Changing Sexually Abusive Behaviour’. These 11 steps form the foundation of the intervention. In this paper we describe how we use the 11 steps, with accompanying illustrative vignettes and question cards describing juvenile sexual abusers at various points along the continuum of change, in order to promote the acceptance of responsibility for abusive behaviour and the development of skills to prevent reoffending. Examples of the vignettes are provided, along with a discussion of how they can be used to motivate change, develop healthy group norms in treatment and set individual goals for clients. Finally, we highlight the possibility of future applications of this intervention with male adult abusers, adolescent and adult female abusers, parents groups, significant other groups, individual clients and children with sexually aggressive behaviour.
