The purpose of this study was to describe the physical activity levels of urban inner city preschoolers while attending Head Start, the federally funded preschool program for children from low-income families. Participants were 158 African American children. Their physical activity during Head Start days was measured using programmed RT-3 accelerometers. Results revealed that the children spent the most time in sedentary and light physical activity, while their participation in moderate-to-vigorous physical activities was low. Given the sedentary class format and limited physical space for the Head Start programs observed, we suggest adding a structured physical activity component to Head Start schools to fight the overweight and obesity crisis.  相似文献

在淹水培养条件下(土/水=2 g/40 mL),研究连二亚硫酸钠(200 mmol/L Na2S2O4)对p,p'-DDT在自然土和Na2S2O4还原土壤中降解历程的影响及机理.在自然土和还原土中添加Na2S2O4促进p,p'-DDT降解,2 d降解率分别为73%和79%,随后降解缓慢.p,p'-DDT在土壤中降解为p,p'-DDD和p,p'-DDE.p,p'-DDT主要被Na2S2O4降解,Na2S2O4还原土壤产生的Fe2+也有贡献.Na2S2O4与Fe2+体系对修复DDTs污染土壤有应用前景.  相似文献

孙子兵法是我国现在最早的兵书,自流传至今约2500年存在多种版本。从最早的魏武帝注本,到宋朝的《武经七书》本、吉天宝撰《孙子十家注》本,再到清朝孙星衍校定的《孙子十一家注》,再加上七十年代银雀山汉墓竹简本《孙子》的出土,为《孙子兵法》的研究提供了充分的文献材料。本文简单考察《孙子兵法》版本的流变情况,以此来更好地学习和研究《孙子兵法》。  相似文献

马歇尔计划不只是美国政府内少数精英设计出来的,而且在相当程度上也是美国一些利益集团加以推进的结果.这些美国商业、劳工等利益团体不但通过发布声明、发表演讲支持马歇尔计划,而且还组建哈里曼委员会直接参与到该计划政策的制订中,对后来马歇尔计划的实施产生了重要影响.  相似文献

Objectives:

Through interviews with the National Library of Medicine''s MedlinePlus Go Local collaborators, an evaluation team sought to identify process characteristics that are critical for long-term sustainability of Go Local projects and to describe the impact that Go Local projects have on sponsoring institutions.

Methods:

Go Local project coordinators (n = 44) at 31 sponsor institutions participated in semi-structured interviews about their experiences developing and maintaining Go Local sites. Interviews were summarized, checked for accuracy by the participating librarians, and analyzed using a general inductive methodology.

Results:

Institutional factors that support Go Local projects were identified through the interviews, as well as strategies for staffing and partnerships with external organizations. Positive outcomes for sponsoring institutions also were identified.

Conclusions:

The findings may influence the National Library of Medicine team''s decisions about improvements to its Go Local system and the support it provides to sponsoring institutions. The findings may benefit current sponsoring institutions as well as those considering or planning a Go Local project.

Highlights

  • Many project coordinators said they underestimated the level of work their National Library of Medicine (NLM) MedlinePlus Go Local projects would require, but most expressed dedication to the project and optimism about project sustainability.
  • An institutional record of community service or outreach and a director who was supportive of the project were important factors in the progress and sustainability of Go Local projects.
  • Go Local projects brought recognition to some sponsoring institutions from their parent institutions or their communities and provided opportunities to establish better relations with other libraries and institutions.
  • Go Local projects ran more smoothly when a person, even a temporary hire, with dedicated time for the project was in charge during the initial building phase. Volunteer assistance has been difficult to motivate and sustain.

Implications

  • NLM''s Go Local proposal guidelines accurately identify the factors that institutions should pay close attention to when planning a Go Local project.
  • NLM should emphasize continuity plans to address project coordinator turnover.
  • NLM should develop a more formal orientation plan for new project coordinators to assist program continuity at the sponsoring institutions.

通过对石楠进行不同土壤类型、苗木生长与时间的生长关系及苗木密度与苗木质量的关系试验对比,掌握石楠育苗技术措施.结果表明石楠育苗在江川不同类型的土壤上均适应;播种时间以1~2月为宜;地苗培育密度以300~500株/m2最好,超过500株/m2时,苗木高径比差异显著,苗木质量明显降低;地苗移袋时间以播种后120~150天(5~7月)为宜.  相似文献

To succeed academically, college students must actively construct course information, synthesize this information with information from texts and other resources, understand this information so that they can succeed on various forms of assessments and ultimately retain this information for the long term. While the complexity of these demands has been modeled somewhat metaphorically, there has been little ecologically valid research into learning in authentic classroom contexts. The present study examines the interrelationships among student perceptions of the learning context, test complexity, study strategies, and academic performance. Results of a path analysis demonstrated that perceptions of the teaching format and test complexity were positively related to the study strategies reported, and these study strategies were further related to the reported course performance.  相似文献
