The current study examines the association between parental support and adolescent sleep under varying levels of family stress. Participants included 316 adolescents (Mage = 16.40 years, 43% male) and their parents (Mage = 45.67 years, 91% mothers) from diverse ethnic backgrounds. Both adolescents and parents completed questionnaires and adolescents wore wrist actigraphs and completed self‐reports on their sleep for 7 consecutive days. Results indicated that under contexts of family stress, more parental support was linked to longer sleep duration, less sleep variability, and less time spent awake during the night. Findings suggest that under contexts of family stress, cohesive family relationships may provide a sense of stability and security that is necessary for healthful sleep. 相似文献

The study described in this article takes the view that distance education programs are dynamic systems with multiple constituencies.
Literature on distance education programs as complex systems and on the critical constituency approach to program evaluation
was used to guide the development of a questionnaire designed to assess the components of a distance education program. Instrument
development was conducted in four phases using both quantitative and qualitative methods. The data from this study suggest
that there are four major components of effectiveness in distance education programs: instruction, management, telecommuting,
and support. Within each of these components there are from two to five subcomponents, 14 components in all, which can be
used to assess distance education programs. The assessment scale which was developed measures these four components and their
subcomponents. 相似文献

Effects of problem-based learning as reported in curricular comparison studies have been shown to be inconsistent over different medical schools. Therefore, we decided to summarize effects of a single well-established problem-based curriculum rather than to add up sometimes-conflicting findings from different problem-based curricula. Effect sizes were computed for 270 comparisons. The results suggest that students and graduates from the particular curriculum perform much better in the area of interpersonal skills, and with regard to practical medical skills. In addition, they consistently rate the quality of the curriculum as higher. Moreover, fewer students drop out, and those surviving need less time to graduate. Differences with respect to medical knowledge and diagnostic reasoning were on average positive but small. These outcomes are at variance with expectations voiced in recent contributions to the literature. They demonstrate that constructivist curricula can have positive effects on learning even if they deemphasize direct instruction. 相似文献

摘要：习近平总书记高度重视体育事业，并围绕建设体育强国，加快“健康中国”建设发表了系列重要讲话。习近平关于体育系列重要讲话系统地阐述了对体育的认识与观点，是习近平体育观的集中体现。文章根据习近平系列重要讲话、有关体育指示的文献资料,应用原典分析法和对照式研究方法，系统分析和探析了习近平的体育观，深刻学习和全面领会了习近平新时代中国特色社会主义思想。首先，习近平体育观，涵盖严谨的科学体系。习近平明确指出，“人民身体健康是全面建成小康社会的重要内涵”，这既是“体育定位的新论”，又是习近平体育观的逻辑起点。“两大发展思想”，是习近平体育观的根本指导方针。“两大战略目标”，是习近平体育观的战略目标体系。“六大战略任务”，是习近平体育观的发展战略任务。“深化体育三大改革”是习近平体育观的发展动力机制。“坚持党的领导”是习近平体育观的制度保证；其次，习近平体育观具有坚持体育的问题导向、坚持体育发展的人民性、时代性、社会引领示范性、坚持体育创新驱动性的创新特征，这彰显了习近平体育观的伟大时代价值；最后，习近平体育观是新时代的创新性理论，是建设体育强国，努力实现建设“健康中国”目标的指导思想。 相似文献

The Experience Corps?, a community-based intergenerational program, was developed to promote the health of older adults, while simultaneously addressing unmet social and academic needs in public elementary schools. The model was designed to draw on, and potentially activate, the wisdom of older adults. This paper explores the nature of wisdom-related knowledge and how older adults may apply such knowledge when tutoring and mentoring young children, as well as the potential for the intergenerational transmission of wisdom from the older adult volunteers to the school children being mentored by them. Developing an understanding of these issues may provide a basis for the creation of more extensive wisdom-generating opportunities for both older and younger generations. 相似文献

课程文化的实质,是课程文化最根本、最深层、最终极的规定性。以往的研究侧重从课程的角度或文化的角度来理解课程文化的内涵,应该说这是理解课程文化内涵的一种视角。本文从课程与文化两个概念的共同属性来把握课程文化的内涵。它是主体发展的文化资源。 相似文献

当今世界主要市场经济国家准备金率及其调整频率一般很低,部分国家甚至完全取消准备金工具使用,而我国不仅准备金率较高而且调整频繁,是重要的货币政策工具。准备金制度地位和作用巨大反差的原因在于,其调控目标和发挥作用的金融环境的不同。短期来看,准备金率依然是我国央行倚重的货币政策工具,但长期来看,弱化其使用是必然趋势,而弱化的主要条件是外部经济失衡问题明显好转、金融体系流动性过剩局面得到明显缓解、利率市场化机制基本形成。 相似文献
