This article is the first of two consecutive reviews on the major empirical studies which have been carried out in an attempt to estimate the prevalence of child sexual abuse among females. The research is structured in terms of three sample categories: (a) probability and non-probability samples of the general population; (b) college student samples; and (c) clinical inpatient and outpatient samples. This part of the review deals with (a) and (b) and highlights a number of unresolved methodological issues which may contribute to the variance in reported prevalence rates. These include a myriad of definitions of child sexual abuse and different methods of eliciting information on possible histories of abuse. Despite these problems. taken as a whole the prevalence studies indicate the significant numbers of people who have experienced abuse and who are willing to disclose aspects of these abusive experiences.  相似文献

Most European welfare states today have said farewell to themale breadwinner–female caretaker model. Still, childcare policy has a different pace and shape in each country.This article studies the (late) origins as well as the diversityin Danish and Flemish (Belgian) child care policy. In Denmark,a universal child care provision was made possible because ofthe advocacy coalition of women with social pedagogues. Theypromoted the ideal of professional care. To combat the idealof full-time motherhood, the Flemish Catholic women’smovement strived for subsidizing childminders—the idealof surrogate motherhood—supported by the Christian DemocraticParty. Both strategies led to comparatively high levels of childcare provisions, but also to very different contents and shapes.In short, one of the factors that shaped child care policy isthe promotion of different (moral) ideals of care by the women’smovement, together with other—often more powerful—allies,and backed up by parental preferences.  相似文献

Expressions for the entropy, the Kullback-Leibler information, and the I α-information are established for distributions of progressively Type-II censored order statistics. These results are used to identify minimum and maximum information censoring plans. In particular, we find minimum and maximum entropy plans for DFR, exponential, Pareto, reflected power, and Weibull distributions. The results for Kullback-Leibler and I α-information hold for any continuous distribution.  相似文献

This study sought to examine school anxiety and depression by parents’ immigrant status and identify differences by region of birth and language proficiency. Data were used from the Early Childhood Longitudinal Study‐Kindergarten Cohort, a nationally representative and longitudinal study of students in the United States. The analytic sample included 6,156 youth. Linear regression models predicted school anxiety and depression of American eighth grade students from English proficiency and parents’ region of birth. Controlling for demographic covariates, there was no significant difference in school anxiety or depression between youth with American‐born parents and those with parents born in any major world region. With the inclusion of an interaction between language proficiency and region of birth, children with limited English proficiency from Europe (B = 2.86, 95% CI = 2.16, 3.55), Central America (B = 1.52, 95% CI = 0.73, 2.31), Asia (B = 1.48, 95% CI = 0.55, 2.40), and South America (B = 0.85, 95% CI = 0.08, 1.61) had significantly heightened school anxiety compared to native‐English speakers with native‐born parents. When considering sources of school anxiety, it was revealed that over 60% of these youth worried about doing well in school. Future research should explore interventions to increase English proficiency and ease school‐related stress among children of immigrants.  相似文献

We investigate retailers’ dynamic pricing decisions in a stylized two‐period setting with possible supply constraints and demand from both myopic and strategic consumers. We present an analytical model and then test its predictions in a behavioral experiment in which human subjects played the role of pricing managers. We find that the fraction of strategic consumers in the market systematically moderates the optimal pricing structure. When this fraction exceeds a certain threshold, the retailer offers relatively small late season markdowns to discourage strategic consumers from waiting and to incentivize them to buy during the early season; otherwise, the retailer offers relatively large markdowns to divert all strategic consumers to the late season, where the majority of revenue is made. Our model analyses suggest that the latter policy is optimal under fairly broad conditions. Our experiment shows that after some significant learning, aggregate behavior is able to approximate the key qualitative predictions from our model analysis, with one notable deviation: in the presence of a mixture of myopic and strategic consumers, subjects act somewhat myopically – they underprice and oversell in the main selling season, which significantly limits their ability to generate revenue in the markdown season.  相似文献

This research examines whether peer-led prevention programs are preferable to adult-led programs. Participants were 2,447 students in 94 classes, from 31 schools running drug prevention programs. The schools were divided into two groups according to the model they used in their program: fifteen schools used peer-led model, while sixteen used the adult-led model. A 46-item questionnaire was constructed in order to examine the students' perception of the programs. The results show that all the input measures (content, atmosphere, openness, discipline, facilitators' competence) and the outcome measures (satisfaction, knowledge, avoidance, curiosity, personal relationship) were perceived as more positive in the peer-led model. The differences were small, but significant. While the findings suggest that the peer-led model has a somewhat greater potential for primary prevention, the differences found do not enable us to state with certainty that this model is preferable for primary prevention purposes.  相似文献
