Child maltreatment often has a negative impact on the development of social behavior and health. The biobehavioral mechanisms through which these adverse outcomes emerge, however, are not clear. To better understand the ways in which early life adversity affects subsequent social behavior, changes in the neuropeptide oxytocin (OT) in children (n = 73) aged 8.1–11.5 years following a laboratory stressor were examined. Girls with histories of physical abuse have higher levels of urinary OT and lower levels of salivary cortisol following the stressor when compared to controls. Abused and control boys, however, do not differ in their hormonal responses. These data suggest that early adversity may disrupt the development of the stress regulation system in girls by middle childhood. 相似文献

With globalization, the world has become more interconnected and interdependent, with people, capital, and ideas rapidly migrating across borders. Yet, along with greater global interdependence and increased diversity within societies, economic and social inequalities have deepened, making poverty one of the leading global problems. To lessen poverty around the world, better integrate immigrant groups into societies, and enhance stability, both societies and education systems are dedicated to fostering social cohesion as a key objective. Yet, still little is known about the extent to which immigration and socioeconomic status are predictive of social cohesion. Using cross-national data from the 2009 International Civic and Citizenship Study for 38 countries, this article further investigates the link between poverty, immigration, education, and social cohesion. Findings indicate that socioeconomic status is an important influence on social cohesion of immigrant students and that schools play an important role in fostering social cohesion. 相似文献

Doug Kirby transformed the field of sex education by conducting rigorous research that led to new, critical insights about ways to strengthen programmes, evaluation and policies related to sexual health throughout the world. Throughout his career, Kirby was meticulous in compiling evidence and translating findings into actionable recommendations for interventions, research and policy. He published more than 150 scientific articles, book chapters and monographs that have been widely cited and more than 900,000 copies of his publications have been distributed. Kirby's impact has been recognised with awards from numerous professional organisations and his unique and powerful scientific voice is greatly missed by his colleagues and friends. 相似文献

Although it is clearly established that an effective instructional systems design (ISD) process requires evaluation, previous studies provide evidence to show that everyday practices of instructional designers do not include sufficient or appropriate evaluation. Research suggests that organizational barriers and lack of support for evaluation are a leading cause of its inadequate usage. Without appropriate and sufficient evaluation practices, it is impossible to maintain the integrity of the systematic quality of ISD and threatens to undermine the entire concept of instructional design. This article first examines the purposes and importance of evaluation. Second, it reviews research that describes the less‐than‐optimal performance of practitioners as it relates to conducting evaluation, along with identifying causes for this performance deficiency. Third, it proposes using a model of human performance technology for improving the environment leading to implementation of evaluation. 相似文献
