This study analyzes correlates of the acceptability of physical punishment of children in Europe. The design was a three‐level ordinal logistic regression of 10,812 people nested within 208 localities (cities), nested within 14 countries of the European Union. Results showed that higher levels of acceptability were reported by men, the older, the less educated, and those who perceived that violence against children was less frequent in their own country. At the country level, the existence of laws prohibiting physical punishment of children as well as a lower number of child maltreatment deaths were significantly associated with lower levels of acceptability of physical punishment of children. Findings suggest that education efforts at the individual and population level are needed.  相似文献

World health reports highlight the increasing prevalence of mental health problems and the need to recognize that mental well‐being is a fundamental aspect of any health policy. The scale and cost of mental health problems mean that appropriate policies and strategies must be developed and implemented. In Ireland this is a period of substantial review and reflection on mental health policy and practice, but to date little consideration has been given to the development of a cross‐border strategy. Cooperation and collaboration has been largely dependent on the leadership of a number of individuals supported by short‐term European Union funding. This paper is informed by a study which was concerned with examining the issues associated with promoting mental health across the Irish border. Insights were provided by 38 individuals who were involved in the delivery of cross‐border mental health services in the North West region. The article argues that there is substantial support for working across borders and developing sustainable cross‐border health strategies. In the absence of a statutory all‐Ireland coordinated policy overseeing the development of mental health promotion, the sustainability of projects emerged as a key issue. The results suggest that whilst much innovative and creative work has been undertaken by committed individuals, what is now required is a strategic response from both the British and Irish governments which will ensure the needs of service users in these deprived border regions can be effectively addressed. Also, at a policy level this strategic development would be seen as a reflection of the value placed on promoting mental health and well‐being.  相似文献

Abstract

We propose a simple procedure based on an existing “debiased” l1-regularized method for inference of the average partial effects (APEs) in approximately sparse probit and fractional probit models with panel data, where the number of time periods is fixed and small relative to the number of cross-sectional observations. Our method is computationally simple and does not suffer from the incidental parameters problems that come from attempting to estimate as a parameter the unobserved heterogeneity for each cross-sectional unit. Furthermore, it is robust to arbitrary serial dependence in underlying idiosyncratic errors. Our theoretical results illustrate that inference concerning APEs is more challenging than inference about fixed and low-dimensional parameters, as the former concerns deriving the asymptotic normality for sample averages of linear functions of a potentially large set of components in our estimator when a series approximation for the conditional mean of the unobserved heterogeneity is considered. Insights on the applicability and implications of other existing Lasso-based inference procedures for our problem are provided. We apply the debiasing method to estimate the effects of spending on test pass rates. Our results show that spending has a positive and statistically significant average partial effect; moreover, the effect is comparable to found using standard parametric methods.  相似文献

Abstract. While it is a popular selection criterion for spline smoothing, generalized cross‐validation (GCV) occasionally yields severely undersmoothed estimates. Two extensions of GCV called robust GCV (RGCV) and modified GCV have been proposed as more stable criteria. Each involves a parameter that must be chosen, but the only guidance has come from simulation results. We investigate the performance of the criteria analytically. In most studies, the mean square prediction error is the only loss function considered. Here, we use both the prediction error and a stronger Sobolev norm error, which provides a better measure of the quality of the estimate. A geometric approach is used to analyse the superior small‐sample stability of RGCV compared to GCV. In addition, by deriving the asymptotic inefficiency for both the prediction error and the Sobolev error, we find intervals for the parameters of RGCV and modified GCV for which the criteria have optimal performance.  相似文献

This paper studies the special case of the triangular system of equations in Vytlacil and Yildiz (2007), where both dependent variables are binary but without imposing the restrictive support condition required by Vytlacil and Yildiz (2007) for identification of the average structural function (ASF) and the average treatment effect (ATE). Under weak regularity conditions, we derive upper and lower bounds on the ASF and the ATE. We show further that the bounds on the ASF and ATE are sharp under some further regularity conditions and an additional restriction on the support of the covariates and the instrument.  相似文献

Increasingly, nonprofit organizations engage in interorganizational collaboration to address large‐scale social problems. Scholarship typically focuses on the characteristics of both within‐sector and cross‐sector partnerships of two collaborating organizations or all partnering organizations involved in a collaboration, but we know little about the patterns of interorganizational relationships that single nonprofit organizations maintain. This research draws upon surveys from 452 nonprofits and introduces nonprofit network portfolios, which we define as the number, integration, intensity, and duration of relationships that nonprofits purposefully develop with other organizations. Using 12 network measures, Ward cluster analysis revealed three distinct network portfolios: restricted within‐sector (n = 319, 70.58%), which included limited collaboration and prioritized within‐sector partnerships; robust within‐sector (n = 80, 17.70%), which included more nonprofit partnerships than restricted within‐sector portfolios; and cross‐sector (n = 53, 11.72%), which had a rich assemblage of integrative partnerships with nonprofits, businesses, and government agencies. Further, nonprofits that maintained each type of portfolio differed in their revenue and social mission, suggesting these factors are related to the types of collaboration that nonprofits maintain. This study makes contributions to existing research on interorganizational networks and cross‐sector collaboration and suggests practical and policy implications for nonprofit network management.  相似文献

Recent research in information systems and operations management has considered the positive impacts of information technology (IT). However, an undesirable side effect of firms’ increasing reliance on IT to support the distribution and delivery of goods and services to customers is a greater exposure to a diverse set of IT security risks. One such risk is intentional employee misuse of technology resources. In this article, we draw upon modern deterrence frameworks to develop a predictive model of technology misuse intention that incorporates formal and informal sanctions as well as employment context factors. The model specifies previously untested relationships between formal and informal sanctions, thereby providing fresh insight into the role of sanctions in deterring technology misuse in organizations. Our results suggest that a predisposition toward the need for social approval and moral beliefs regarding the behavior are key determinants of technology misuse. Contrary to criminological research that has questioned the relative importance of formal sanctions in the deterrence process, we also found that the threat of formal sanctions has both direct and indirect influences on technology misuse intention. Further, from an employment context standpoint, employees who spend more working days away from the office (i.e., “virtual” mode) appear more inclined to misuse their organization's technology resources. The findings have implications for the research and practice of technology management.  相似文献
