目的:基于决策树模型探讨引起幼儿超重的关键因素。方法:招募南昌市23所幼儿园5870名3~6岁幼儿,测量身高、体重;问卷调查幼儿身体活动、静坐行为、出生信息,父母的育儿方式、身体形态、锻炼行为和家庭情况,并将其划分为36个变量;采用IBM SPSS modeler软件创建CHAID决策树模型,筛选幼儿超重的关键性因素。结果:CHAID模型准确率达85.23%。CHAID模型结果显示,8个变量与幼儿超重有较强关联性,各变量按重要性排序依次为室外身体活动时间、父亲BMI、母亲BMI、父亲收入、室内身体活动时间、父亲受教育程度、喂养方式、看电视时间。结论:身体活动尤其是室外身体活动与幼儿超重的关系最为密切,父母肥胖程度、父亲收入与受教育情况、喂养方式、静坐行为也是导致幼儿超重的关键性因素。 相似文献

This paper reports initial findings of a research project in Queensland, Australia that did not adopt recommended practices from listings established in other countries for early childhood intervention services. Instead, a contextual and participatory process served to determine a relevant listing of program quality indicators for a large, early intervention service conducted by the state Department of Education (Stage 1). Thirty-one indicators of program quality were identified for this particular service. To validate these indicators and to gather additional information about their implementation, a statewide survey was conducted (Stage 2). For each of the 31 indicators, parents and staff from within this service were asked to (a) indicate their level of acceptance, (b) report on current use, and (c) comment on barriers to implementation. Results provide strong support for the indicator listing and reveal high level of indicator acceptance accompanied by a lower level of indicator implementation. Lack of time and lack of staff were identified as the primary barriers to implementation across all indicators. The validated indicator listing for Early Special Education (Qld) services is provided. 相似文献

论区域图书馆区位设置与规划 总被引:1,自引:0,他引:1
从空间角度看,区域图书馆区位设置与规划跟图书馆功能发挥密切相关,能有效提高区域层面图书馆整体服务效率.文章所指区位不仅仅指区域地理位置、区域经济等要素,同时指图书馆读者和文献资源等要素的位置和空间范围,是系统观指导下图书馆各要素在区域的综合集成.个体图书馆区位设置.指以服务人口等确定图书馆规模和位置,合理设置内部空间结构.区域图书馆整体规划,指客观分析区域区位,系统规划区域内图书馆的设置数量、不同规模和类型图书馆的组合结构等.我国图书馆的现代化发展中,技术对图书馆区位设置的影响日益显现,国家宏观调控和区域图书馆自主探索有机结合,尤其是东莞等沿海区域图书馆区位设置与规划取得了宝贵的经验. 相似文献

通过分层抽样,选取广东省东莞市的1289名居民为样本,对其参与社会阅读推广活动情况进行调查。通过对社会阅读活动与信息贫富状况的关联分析发现,信息富裕者更有可能去主动搜集关于读书节等社会大型阅读推广活动的信息,从而使这一人群中知晓读书节活动的人数比例高于其他人群。信息贫困一方面表现为"信息获取意愿的贫困",另一方面则表现为个体对信息获取缺乏(积极的或消极的)体验。对现有社会公共信息资源和服务利用不足是导致信息贫困的重要原因之一。购书费用、年借阅量和数字阅读时间的增加对信息贫富分化影响显著,但这些因素对男性和女性产生的影响有所不同。 相似文献

Poor post-school outcomes for youth with disabilities have consistently been reported internationally. Interagency collaboration between school systems and post-school services is critical and key to improving post-school life for these youth. An initial Queensland study that benchmarked the teacher practice of 104 transition teachers and associated personnel indicated that interagency collaboration practices had the lowest levels of implementation. These results were the motivation behind a second study which investigated the hypothesis that lack of teacher control over interagency collaboration practice formed a roadblock for effective transitioning of youth with disabilities. Results generally confirmed the hypothesis and provide further understanding about the multi-faceted nature of interagency collaboration and the stakeholders involved in this process. Three interconnected actions are proposed to bypass identified roadblocks. If these actions are put in place, schools should improve their connections with post-school services, teachers should enhance their practice, and students should achieve improved post-school outcomes. 相似文献
