This study evaluates and synthesizes qualitative evidence addressing factors affecting a child’s decision to disclose an experience of sexual abuse. Childhood sexual abuse is a devastating crime, with long-term negative impacts. Understanding the factors that affect a child’s decision to disclose is vital. Disclosure enables access to support and protection, both therapeutically and legally. A systematic review was conducted focusing on factors affecting a child’s decision to disclose an experience of sexual abuse. Seven studies were identified, quality appraisal undertaken, and meta-ethnography used to synthesize the studies. Six new super-ordinate themes were developed: Fear of what will happen; Others’ reactions: fear of disbelief; Emotions and impact of the abuse; An opportunity to tell; Concern for self and others; and Feelings toward the abuser. Themes indicated the importance of support, structure, and opportunity to facilitate disclosure and should be utilized by agencies to develop practices that facilitate disclosures. 相似文献

This article presents a qualitative analysis of the experience of parenting of mothers with dissociative disorders. This analysis was performed to complement the quantitative analysis of problems of mothers with dissociative disorders that Benjamin, Benjamin, and Rind (1996) presented previously. They found that the functioning of these mothers, as well as their subjective experience of mothering, was poorer that that of either clinical or nonclinical control mothers. Our goal was to provide a clearer, richer picture of their problems in parenting. Using the mothers' own words, we describe how the five symptom areas of dissociation (amnesia, depersonalization, derealization, identity confusion, and identity alteration) impeded their parenting efforts. We conclude with a discussion of the necessity of addressing parenting in the treatment of client-mothers with dissociative disorders. 相似文献

ABSTRACT. The problem of boundary bias is associated with kernel estimation for regression curves with compact support. This paper proposes a simple and uni(r)ed approach for remedying boundary bias in non-parametric regression, without dividing the compact support into interior and boundary areas and without applying explicitly different smoothing treatments separately. The approach uses the beta family of density functions as kernels. The shapes of the kernels vary according to the position where the curve estimate is made. Theyare symmetric at the middle of the support interval, and become more and more asymmetric nearer the boundary points. The kernels never put any weight outside the data support interval, and thus avoid boundary bias. The method is a generalization of classical Bernstein polynomials, one of the earliest methods of statistical smoothing. The proposed estimator has optimal mean integrated squared error at an order of magnitude n −4/5 , equivalent to that of standard kernel estimators when the curve has an unbounded support. 相似文献

Dans cet article, nous examinons différents modèles de rapports avec les forces policières parmi des sous-populations hétérogènes de jeunes, dans les premiers stades de transition de leur carrière criminelle. Nous croyons que la recherche axée sur l'hétérogénéité et sur les premiers stades de la transition vers la criminalité peut nous renseigner sur les éléments de la dynamique comportementale - jusqu'ici ignorés - dans l'étude de l'apparition d'un comportement criminel et de sa persistance. À partir de données policières informatisées provenant d'une grande ville de l'ouest du Canada, nous utilisons certains modèles de survie basés sur des événements pour dégager des modèles d'apparition et de persistance de comportements criminels sur une période de six mois, dans les premiers rapports avec la police. Les résultats démontrent des modifications importantes à court terme dans le comportement criminel de sousgroupes de jeunes de niveaux différents. Certains semblent avoir un comportement criminel ponctuel, qu'ils abandonnent par la suite, tandis que d'autres continuent de se comporter en criminels, en augmentant la fréquence et le taux d'infractions. Toutefois, certains modèles hétérogènes existent au sein de ces sous-groupes de jeunes délin quants dans les premières phases de développement de la criminalité. We investigate distinctive patterns of police contacts among heterogeneous subpopulations of youths in the early transition stages of their criminal careers. We argue that research focussing upon heterogeneity and the initial transition stages of criminality can provide insights into behavioural dynamics previously overlooked in the study of the onset and development of criminal careers. Using computerized police archival data from a large western Canadian city, we employ event history survival models to estimate patterns of onset and persistence for delinquent careers over six-month intervals in the early stages of police contact. Our results provide strong evidence of meaningful short-term change in offending among multiple levels of youth subgroups. Some youths appear to offend only briefly and then desist, while others continue offending and at a higher rate. However, there also appear to be patterns of heterogeneity within as well as between these subgroups of young offenders during the early stages of criminal careers. 相似文献

Threshold models have a wide variety of applications in economics. Direct applications include models of separating and multiple equilibria. Other applications include empirical sample splitting when the sample split is based on a continuously‐distributed variable such as firm size. In addition, threshold models may be used as a parsimonious strategy for nonparametric function estimation. For example, the threshold autoregressive model (TAR) is popular in the nonlinear time series literature. Threshold models also emerge as special cases of more complex statistical frameworks, such as mixture models, switching models, Markov switching models, and smooth transition threshold models. It may be important to understand the statistical properties of threshold models as a preliminary step in the development of statistical tools to handle these more complicated structures. Despite the large number of potential applications, the statistical theory of threshold estimation is undeveloped. It is known that threshold estimates are super‐consistent, but a distribution theory useful for testing and inference has yet to be provided. This paper develops a statistical theory for threshold estimation in the regression context. We allow for either cross‐section or time series observations. Least squares estimation of the regression parameters is considered. An asymptotic distribution theory for the regression estimates (the threshold and the regression slopes) is developed. It is found that the distribution of the threshold estimate is nonstandard. A method to construct asymptotic confidence intervals is developed by inverting the likelihood ratio statistic. It is shown that this yields asymptotically conservative confidence regions. Monte Carlo simulations are presented to assess the accuracy of the asymptotic approximations. The empirical relevance of the theory is illustrated through an application to the multiple equilibria growth model of Durlauf and Johnson (1995). 相似文献

There has been intense debate in Australia regarding how asylum seekers who arrive by boat should be treated. Some call for compassion towards those prepared to risk their lives to seek protection, whereas others believe ‘boat people’ should not be allowed into the country. This article uses data from a large representative sample of young people in Queensland, Australia, to understand the acceptance of asylum seekers by young people in Australia. The findings suggest that young Australians are more accepting than the Australian adult population. Several social and political background factors were also found to be associated with the belief that ‘boat people’ should be permitted into Australia. Fewer factors, however, are associated with the trust young Australians have in people from another country. This suggests that while some young Australians may believe boats carrying asylum seekers should not be turned away, fewer might be prepared to enter into trusting relationships with ‘boat people’ should they resettle in Australia. 相似文献

Welfare policy has been controversial and support is often drawn along political affiliation lines, the economic return of investment in welfare programs is frequently cited as a justification for new and expanded policies. To investigate the direct and indirect effects of welfare programs on economic performance, the authors develop a multilink approach, through employment and investment. The relationship is then tested with data from each of the United States from 1976 to 2006. Findings show welfare programs have no direct effect on a state's economy. Indirectly, welfare has a negative effect through investment, though the effect on employment is minimal. 相似文献

Leadership efficacy: Review and future directions 总被引:1,自引:0,他引:1
The concept of leader efficacy has received relatively little attention in the leadership literature. This is somewhat surprising given that effective leadership requires high levels of agency (i.e., deliberately or intentionally exerting positive influence) and confidence. This review uses existing theory and research on leader efficacy as a point of departure for proposing an expanded and multi-level framework for understanding the domain of leadership efficacy that includes leader, follower, and collective efficacies. The primary goals are to provide a conceptual framework to stimulate future theory and research on building efficacious leadership and to understand how such leadership develops and has implications for effective performance. 相似文献
