This study examined the effects of program pacing, defined as the rate of scene and character change per minute, on infants’ visual attention to video presentations. Seventy‐two infants (twenty‐four 6‐month‐olds, twenty‐four 9‐month‐olds, twenty‐four 12‐month‐olds) were exposed to one of two sets of high‐ and low‐paced commercial infant DVDs. Each DVD was approximately 5‐min long, and the order the DVDs were viewed was counterbalanced for pace. Attention was higher during rapidly than slowly paced DVDs, particularly for the 6‐ and 9‐month‐old infants. These results support previous research documenting that attention is initially controlled by exogenous qualities (e.g., rapid pace), but with development and experience becomes more influenced by endogenous factors.  相似文献

Bryson和Mowbray曾在1981年写文章批判政府盲目使用“社区”一词,并谈到关系着社区的循证政策如何在2005年成为一句空洞的政治口号。两篇文章都刊登在澳大利亚的社会问题期刊上。本文通过定性分析的方法搜集数据,考察南澳大利亚州某地方政府对“社区”的主观和现实意义作何理解,以评估其与社会政策制定者所使用的“社区”一词的吻合度。笔者认为,在2009年,社会政策制定者所使用的“社区”与围绕此主题展开的大量研究或者当前个体与家庭的情况缺乏共鸣,从而导致针对社区的社会政策其初衰与效果不相匹配。  相似文献

The payday lending industry has grown considerably in recent years, reflecting both widespread economic insecurity and market neglect by the traditional banking sector. Outlets are now commonplace in many communities across America. Accused by many of predatory practices, payday lenders can be viewed as financial hazards in already economically distressed communities. Using a Geographic Information System (GIS) and associated statistical analyses, this paper examines the social ecology of payday lending along the Front Range communities of Colorado. Comparison of means and logistic regression results reveal how communities’ composition by class, occupation, race/ethnicity, nativity, age, and military affiliation affect their likelihood of hosting payday lending.  相似文献

This paper describes an innovative application of statistical process control to the online remote control of the UK's gas transportation networks. The gas industry went through a number of changes in ownership, regulation, access to networks, organization and management culture in the 1990s. The application of SPC was motivated by these changes along with the desire to apply the best industrial statistics theory to practical problems. The work was initiated by a studentship, with the technology gradually being transferred to the industry. The combined efforts of control engineers and statisticians helped develop a novel SPC system. Having set up the control limits, a system was devised to automatically update and publish the control charts on a daily basis. The charts and an associated discussion forum are available to both managers and control engineers throughout the country at their desktop PCs. The paper describes methods of involving people to design first-class systems to achieve continual process improvement. It describes how the traditional benefits of SPC can be realized in a 'distal team working', and 'soft systems', context of four Area Control Centres, controlling a system delivering two thirds of the UK's energy needs.  相似文献

The intention of this review article is to consider some of the major social changes that have had an impact on adolescents during the latter part of the last century, and to suggest ways in which the behaviour and development of young people in the present century will alter in response to such a change. It is argued that alteration in the labour market and in family composition and structure will have particular effects on young people in the coming years. The article also considers race, gender, sexuality, mental health and social exclusion. The review concludes with some tentative predictions concerning the attitudes and likely behaviours of young people in the twenty first century. Copyright © 2000 John Wiley & Sons, Ltd.  相似文献

The present study describes the depressive symptomatology of 393 parents of prekindergarten children and assesses ethnic differences in the depression scores of these parents and their differential consequences for children's social competence. Data are drawn from the National Center for Early Development and Learning (NCEDL) classroom study, a national, longitudinal study examining the quality and outcomes of prekindergarten programs operated in schools or under the direction of state and local educational agencies, and the supplemental NCEDL familial and social environments study. Analyses indicated that Latino parents were more likely than African‐American and White parents to be depressed. However, as reported by both parents and teachers, behavioral outcomes for African‐American children of parents with elevated depressive symptomatology were worse than children of their Latino and White counterparts. Interactions between ethnicity and depressive symptomatology emerged in the parent‐child relationship, with African‐American parents with elevated depressive symptoms reporting significantly greater levels of conflict in the parent–child relationship than their non‐depressed counterparts. African‐American parents with elevated depression scores were also less likely to be in marital relationships than their non‐depressed counterparts. Among African‐American families, parent–child conflict served as a mediator of the effects of parental depression on child outcomes. Implications for intervention are discussed.  相似文献

Male and female participants were surveyed on abortion attitudes, commitment, and abortion experience. Results revealed a normal distribution of abortion attitudes rejecting the notion that the vast majority of the sample would have significantly pro-choice views. No significant difference was found in overall abortion attitudes of males vs. females, however, individuals with direct abortion experience were found to have significantly stronger pro-choice attitudes than individuals without direct abortion experience. Overall, college students reported a moderate degree of commitment to the issue of abortion. Females were significantly more committed than males, individuals with direct abortion experience were significantly more committed than individuals without direct abortion experience, and individuals with more extreme abortion attitudes were significantly more committed than those with weaker, more ambivalent, attitudes. No significant difference was found in level of commitment between pro-choice and pro-life individuals.  相似文献
