Variations of the boxplot are suggested, in which the sides of the box are used to convey information about the density of the values in a batch. The ease of computation by hand of the original boxplot had to be sacrificed, as the variations are computer-intensive. Still, the plots were implemented on a desktop personal computer (Apple Macintosh), in a way designed to keep their ease of computation by computer. The result is a dynamic display of densities and summaries. 相似文献

This article focuses on the implementation of evidence‐based parenting programmes (EBPPs) in a small sample of urban local authorities in England. The first part discusses the development of government policy, guidance and implementation issues. The second part presents findings from an exploratory study, which focused on the implementation of EBPPs in terms of programme eligibility, fidelity and intensity in six urban local authorities. Implementation was not necessarily in line with policy or guidance. Issues associated with programme fidelity along with concerns about sustainability as a result of cuts in funding are discussed and implications for policy and future research considered. 相似文献

This article examines the historical evolution of the development of social policy toward street children in Russia and makes recommendations for prevention. The historical examination begins with the Soviet period, when statistics on social problems were not publicly known. It continues through the post-Soviet period when there was an emerging awareness about the increasing number of abused, abandoned children and children living on the streets. Etiological factors, such as child maltreatment and parental substance abuse, are then discussed. Based on these etiological factors, the article then proposes a model in which existing institutions and professionals are supported in facilitating an integrated system of primary, secondary and tertiary prevention. This includes improving child protection services and interventions to prevent children leaving their homes, early identification of children who are becoming involved in street life and a continuum of care for children who cannot return home. 相似文献

Despite fears that selective exposure and selective avoidance could deepen polarization and negatively affect the democratic process, few studies have directly studied this phenomenon. This study explores whether selective exposure and avoidance to blogs, social network sites, and Twitter directly influence confidence in Congress and the president or more indirectly through polarization. This study suggests that fears of selective exposure, selective avoidance, and polarization infecting the democratic process appear overstated. First, polarization was positively related to confidence in Congress and the president. Second, selective exposure to social media sites strengthens confidence in the president and in Congress. Twitter boosts confidence in Congress. Third, selective avoidance had a negative influence on other measures, which suggests people seek both information that challenges their views as well as ones that supports them. Finally, selective exposure and avoidance proved weak indicators of polarization. Instead, strength of partisanship is the stronger predictor of confidence in Congress and the president. 相似文献

The present study tested for gender differences in depression and body image among a sample of 6th–8th grade low-income African American adolescents. Gender differences were found, with adolescent girls more likely to report both depressive symptoms and poor body image. The most frequently endorsed body image concern for both boys and girls was the desire to lose weight, with approximately half of the girls in this sample reporting they would like to lose weight. Results of mediational analyses indicate that poor body image mediates the relation between gender and depression in this sample, suggesting that heightened rates of depression, among girls, are due to heightened rates of poor body image. 相似文献
