This study examined the prevalence and severity of intimate partner violence (IPV) among 248 problem gamblers (43 women, 205 men) recruited from newspaper advertisements. The main outcome measures used were the Canadian Problem Gambling Index, the Conflicts Tactics Scale-2, the State Trait Anger Expression Inventory-2, the drug and alcohol section of the Addiction Severity Index and the substance use section of the Structured Clinical Interview for the DSM-IV. In this sample, 62.9% of participants reported perpetrating and/or being the victims of IPV in the past year, with 25.4% reporting perpetrating severe IPV. The majority of the sample (64.5%) also had clinically significant anger problems, which was associated with an increased risk of being both the perpetrator and victim of IPV. The presence of a lifetime substance use disorder among participants who had clinically significant anger problems further increased the likelihood of both IPV perpetration and victimization. These findings underscore the importance of routinely screening gambling clients for anger and IPV, and the need to develop public policy, prevention and treatment programs to address IPV among problem gamblers. Future research to examine IPV among problem gamblers is recommended.  相似文献

The Nordic countries at the same time exhibit a remarkably high participation rate of mothers and a more moderate decline in fertility rates compared to other Western countries. This has been attributed to the fact that the welfare state model and, especially, the family friendly policies chosen in the Nordic countries are unique. In this paper we evaluate the impact of Nordic countries’ family friendly policies on employment, wages and children’s well-being. We demonstrate that, although the ‘Nordic model’ has been successful in boosting female employment, it is a costly solution. Furthermore, family-friendly policies mainly directed towards giving mothers the right to be on long paid maternal leave have adverse effects on women’s wages with consequences for gender equality. Indeed, extensive family-friendly schemes may even have created a ‘system-based glass ceiling’ hindering women’s career progression. There is no evidence however of a trade-off between family-friendly policies and family welfare as effects on child development and children’s well-being of publicly provided child-care are found to be modest or even positive.

This paper reports on a study of over 200 young people going missing from residential and foster care in four local authorities. The proportion of young people missing from residential care was high, ranging from 25 to 71% of all 11 – 16‐year‐olds in mainstream children’s homes. Two types of absence were identified: the ‘runaways’ profile (those who ran away or stayed out) and the ‘friends’ profile (those missing to be with friends). There were variations in levels of risk for different sub‐groups within the sample. Risks included immediate risks of victimization, sexual exploitation (including prostitution), offending and substance misuse. A longer‐term risk of detachment was identified among those going missing often, involving high levels of non‐school attendance, detachment from carers and involvement in offending and in substance misuse. Difficulties in the assessment of risk are discussed and approaches to managing risk for young people who go missing from substitute care are explored. Copyright 1999 John Wiley & Sons, Ltd.  相似文献

Outliers that commonly occur in business sample surveys can have large impacts on domain estimates. The authors consider an outlier‐robust design and smooth estimation approach, which can be related to the so‐called “Surprise stratum” technique [Kish, “Survey Sampling,” Wiley, New York (1965)]. The sampling design utilizes a threshold sample consisting of previously observed outliers that are selected with probability one, together with stratified simple random sampling from the rest of the population. The domain predictor is an extension of the Winsorization‐based estimator proposed by Rivest and Hidiroglou [Rivest and Hidiroglou, “Outlier Treatment for Disaggregated Estimates,” in “Proceedings of the Section on Survey Research Methods,” American Statistical Association (2004), pp. 4248–4256], and is similar to the estimator for skewed populations suggested by Fuller [Fuller, Statistica Sinica 1991;1:137–158]. It makes use of a domain Winsorized sample mean plus a domain‐specific adjustment of the estimated overall mean of the excess values on top of that. The methods are studied in theory from a design‐based perspective and by simulations based on the Norwegian Research and Development Survey data. Guidelines for choosing the threshold values are provided. The Canadian Journal of Statistics 39: 147–164; 2011 © 2010 Statistical Society of Canada  相似文献

This paper reports on a quasi-experimental study which comparedoutcomes for young people referred to specialist family supportteams with those for others referred to mainstream social workteams. Although there was no evidence that the specialist servicewas more effective in promoting changes in child and familyfunctioning, nevertheless, many young people in both groupsshowed improvement in this respect. This paper explores how,why and in what circumstances these positive changes occurred.The factors which moderated or mediated the effectiveness ofinterventions included both risk and protective factors foremotional and behavioural problems and aspects of the interventionsthemselves. The paper explores the mechanisms whereby thesefactors interacted to help or hinder workers’ effortsto promote change. Child and family attributes and histories,the duration of child and family difficulties, motivation andoptimism all moderated the impact of interventions, making changemore, or less, likely to occur. Aspects of the interventionsthemselves also mediated their effectiveness, such as theirecological approach, the strategies used to change child behaviourand parenting style and the development of a therapeutic alliance.These moderators and mediators of change had a stronger impacton the outcome of interventions than differences in servicetype.  相似文献

We study non-Markov multistage models under dependent censoring regarding estimation of stage occupation probabilities. The individual transition and censoring mechanisms are linked together through covariate processes that affect both the transition intensities and the censoring hazard for the corresponding subjects. In order to adjust for the dependent censoring, an additive hazard regression model is applied to the censoring times, and all observed counting and “at risk” processes are subsequently given an inverse probability of censoring weighted form. We examine the bias of the Datta–Satten and Aalen–Johansen estimators of stage occupation probability, and also consider the variability of these estimators by studying their estimated standard errors and mean squared errors. Results from different simulation studies of frailty models indicate that the Datta–Satten estimator is approximately unbiased, whereas the Aalen–Johansen estimator either under- or overestimates the stage occupation probability due to the dependent nature of the censoring process. However, in our simulations, the mean squared error of the latter estimator tends to be slightly smaller than that of the former estimator. Studies on development of nephropathy among diabetics and on blood platelet recovery among bone marrow transplant patients are used as demonstrations on how the two estimation methods work in practice. Our analyses show that the Datta–Satten estimator performs well in estimating stage occupation probability, but that the censoring mechanism has to be quite selective before a deviation from the Aalen-Johansen estimator is of practical importance.

Population aging is being experienced by many rural communities in the United States, as evidenced by increases in the median age and the high incidence of natural population decrease. The implications of these changes in population structure for the daily lives of the residents in such communities have received little attention. We address this issue in this study by examining the relationship between population aging and the availability of service‐providing establishments in the rural United States between 1990 and 2010. Using data mainly from the U.S. Census Bureau and the Bureau of Labor Statistics, we estimate a series of fixed‐effects regression models to identify the relationship between median age and establishment counts net of changes in overall population and other factors. We find a significant but nonlinear relationship between county median age and the total number of service‐providing establishments, and counts of most specific types of services. We find a positive effect of total population size across all of our models. This total population effect is consistent with that found in other research, but the independent effect of age structure that we observe represents a novel finding and suggests that age structure is a salient factor in local rural development and community well‐being.  相似文献

This study examines whether (1) mothers vary in the way they express hostility toward their delinquent adolescent offspring, (2) different types of maternal hostility differentially affect adolescents’ depression and recidivism, and (3) adolescent depression serves as a mechanism through which maternal hostility predicts later reoffending. The sample consists of 1,216 male first‐time offenders, aged 13–17 years (M = 15.80, SD = 1.29). Confirmatory factor analysis supported the premise that maternal hostility could be distinguished into two subtypes: emotional and physical hostility. Adolescent offenders who experienced emotional or physical hostility by their mothers reported greater depressive symptoms and reoffending 6 months later. Further, the relation between maternal hostility (of each type) and adolescent reoffending was partially explained by depressive symptomology.  相似文献

Shareholders are not identical, but differ in their objectives and actions. One difference is the level of delegation of the principal functions to the board, which we suggest can be observed through the level of directors’ compensation. We analyze the difference in board compensation through the concept of governance strategy and suggest two distinct categories of shareholder strategies: the company governance strategy and the financial governance strategy. These strategies create different distributions of governance costs, which we separate into principal costs and agency costs. We claim that the financial governance strategy adopts a higher level of delegation, which implies that the principal costs are assumed by the corporation and that agency costs are higher. This in turn can explain the higher compensation for the directors of the board compared to compensation under the company governance strategy. We test our hypothesis using a three-year panel of Swedish listed corporations and find that shareholders pursuing a financial governance strategy are associated with higher levels of board compensation. These findings suggest the existence of differences in governance strategies, reflected in governance costs through board compensation, among different types of shareholders in a corporation.  相似文献

Measurement of affective states in everyday life is of fundamental importance in many types of quality of life, health, and psychological research. Ecological momentary assessment (EMA) is the recognized method of choice, but the respondent burden can be high. The day reconstruction method (DRM) was developed by Kahneman and colleagues (Science, 2004, 306, 1776–1780) to assess affect, activities and time use in everyday life. We sought to validate DRM affect ratings by comparison with contemporaneous EMA ratings in a sample of 94 working women monitored over work and leisure days. Six EMA ratings of happiness, tiredness, stress, and anger/frustration were obtained over each 24 h period, and were compared with DRM ratings for the same hour, recorded retrospectively at the end of the day. Similar profiles of affect intensity were recorded with the two techniques. The between-person correlations adjusted for attenuation ranged from 0.58 (stress, working day) to 0.90 (happiness, leisure day). The strength of associations was not related to age, educational attainment, or depressed mood. We conclude that the DRM provides reasonably reliable estimates both of the intensity of affect and variations in affect over the day, so is a valuable instrument for the measurement of everyday experience in health and social research.  相似文献
