This article explores the relationship between parental psychological control and parental autonomy granting, and the relations between these constructs and indicators of adolescent psychosocial functioning, in a sample of 9,564 adolescents from grades 9 to 12. Participants completed a comprehensive parenting questionnaire as well as several measures of psychosocial adjustment. Confirmatory factor analyses of the parenting items revealed discrete factors for psychological control and autonomy granting, suggesting that these are distinct parenting constructs rather than opposite ends of a parental control continuum. Moreover, structural equation modeling showed that these factors were weakly correlated and differentially related to adolescent internalizing symptoms. Findings have implications for future conceptualization and measurement of psychological control and autonomy granting, and for research examining their effects on adolescent development. 相似文献

This study examines whether changes in impulse control and sensation‐seeking across adolescence and early adulthood reflect independent or interdependent developmental processes. Data are drawn from a national longitudinal study (N = 8,270; 49% female; 33% Black, 22% Hispanic, 45% non‐Black, non‐Hispanic). An autoregressive latent trajectory model is used to test whether development in one trait influences development in the other. Although levels of these traits are inversely correlated, we do not find evidence that change over time in either trait is influenced by the prior level of the other. This failure to reject the null hypothesis is consistent with the view that sensation‐seeking and impulse control are the products of distinct neuropsychological systems that develop independently of one another. 相似文献

Sedentary behavior has already been associated with mortality, cardiovascular disease, and cancer. Questionnaires are an affordable tool for measuring sedentary behavior in large epidemiological studies. Here, we introduce and evaluate two statistical methods for quantifying measurement error in questionnaires. Accurate estimates are needed for assessing questionnaire quality. The two methods would be applied to validation studies that measure a sedentary behavior by both questionnaire and accelerometer on multiple days. The first method fits a reduced model by assuming the accelerometer is without error, while the second method fits a more complete model that allows both measures to have error. Because accelerometers tend to be highly accurate, we show that ignoring the accelerometer's measurement error, can result in more accurate estimates of measurement error in some scenarios. In this article, we derive asymptotic approximations for the mean-squared error of the estimated parameters from both methods, evaluate their dependence on study design and behavior characteristics, and offer an R package so investigators can make an informed choice between the two methods. We demonstrate the difference between the two methods in a recent validation study comparing previous day recalls to an accelerometer-based ActivPal. 相似文献

Currently, disabilities organizations are increasingly being challenged by the requirement for individualized service, expectations to show personal outcomes, and the need to base their services on evidence-based practices. Social entrepreneurship (SE) is being put forward as an innovative approach for dealing with these challenges. This article presents a systems approach to SE based on a program logic model. This model identifies the input factors (a strong social vision, exploiting opportunities, maximizing resources), throughput strategies (entrepreneurial orientation, critical thinking skills, networking, capacity building), and outcome components (improving people’s lives, community-building, improving society) of SE at the micro, meso, and macro level. Also, the importance of planning for contextual changes as a social entrepreneur is discussed. The article concludes with presenting three inspiring practices regarding SE in the field of disabilities organizations. 相似文献

Marie‐Laurence Flahaux 《The International migration review》2017,51(4):868-892
This study questions the role of migration policy changes in France, Italy, and Spain for return migration to Senegal, by analyzing biographic data from the Migration between Africa and Europe (MAFE‐Senegal) survey and the contextual data of the Determinants of International Migration (DEMIG) VISA and DEMIG POLICY databases that cover major changes in migration policies in these destination countries for the different categories of migrants. Event history logistic regressions reveal that Senegalese migrants are less likely to return when the entry restrictions have become tighter. This result suggests that the decision to return depends on the possibility of migrating again after the return, which is crucial for both theory and policy regarding Western democracies' attempts to regulate migration. 相似文献

The paper addresses the occurrence of improvisation and intuition within dynamic business environments from an emergence theory perspective. As argued, the dynamics of the so-called red queen principle forces competition towards the verge of the manageable, making improvised and intuitive action and decision-making not a shortcoming but a necessity in a successful business context. Particularly, the paper discusses how we may interpret the highly rationalistic acts and outcomes of planning and plans in such chaotic and uncertain contexts. We draw upon a longitudinal study of large industrial project deliveries incorporating more than 25 such deliveries. 相似文献

瑞典顾客满意度晴雨表 总被引:4,自引:0,他引:4
瑞典是世界上第一个在全国范围内测量顾客满意度的国家,建立了瑞典顾客满意度晴雨表(SCSB).SCSB基于瑞典30多个行业100多个企业的顾客年度调查数据对于整个国家经济产出的质量状况进行测量.根据SCSB 在瑞典前3年的发展状况,针对SCSB对瑞典国内各行业的影响结果进行分析,进而得出推论--顾客满意度在供给相同需求各异的行业偏低;在需求和供给相匹配的行业偏高;在高度依赖重复购买的行业偏高;而在垄断行业偏低. 相似文献
