The purpose of this study was to examine the factorial invariance of the Abbreviated Neighborhood Environment Walkability Scale (NEWS-A) across subgroups based on demographic, health-related, behavioral, and environmental characteristics among Nurses’ Health Study participants (N = 2,919; age M = 73.0, SD = 6.9 years) living in California, Massachusetts, and Pennsylvania. A series of multigroup confirmatory factor analyses were conducted to evaluate increasingly restrictive hypotheses of factorial invariance. Factorial invariance was supported across age, walking limitations, and neighborhood walking. Only partial scalar invariance was supported across state residence and neighborhood population density. This evidence provides support for using the NEWS-A with older women of different ages, who have different degrees of walking limitations, and who engage in different amounts of neighborhood walking. Partial scalar invariance suggests that researchers should be cautious when using the NEWS-A to compare older adults living in different states and neighborhoods with different levels of population density.  相似文献

This paper argues that the South African educational restructuring policy proposals are unlikely to become interventions that help bringing about greater development, equity, participation and redress. The reasons for this are manifold. It is contended that the policy proposals are flawed in their conceptualization of the problems and misjudge the educational context and dynamics on the ground. These interventions favour the interests of the more organized and privileged sections of society and only indirectly address the needs of the excluded and disadvantaged. The policy proposals are also based on problematic assumptions about policy and the policy process, and the relationship between policy and practice. Finally, these proposals do not have an appropriate understanding of the change process and are unable to develop strategies to influence the reform process and empower the disadvantaged to struggle for a fairer, more equitable and effective education and training system.  相似文献

This paper reports an investigation via questionnaire into the changes in pastoral care and PSE since 1988 and the Reform Act. The author outlines the key changes since 1988 and constructs several hypotheses. These hypotheses predict that the effects on these two areas will have been negative. However, the results obtained from the survey were more positive than expected. Many respondents saw the changes as having increased the perceived importance of pastoral care.  相似文献

摘要:运动缺乏症(EDD)是一种儿科疾病,特点是中高强度体力活动(MVPA)下降,低于目前的推荐量,也与积极的健康结果(health outcomes)不一致。目前,大多数儿童和青少年符合EDD的诊断标准,因为他们没有达到日常MVPA的最低要求。本文的目的是强调10个与青少年EDD有关的重要研究问题。需要进行重要的研究来更好的定义EDD的临床表现,包括评估体力活动行以确定开始出现EDD的年龄或发育阶段;包括运动技巧和体能的运动起源(kinesiogenesis)的检测;以及对影响青少年MVPA的生活方式因素的评估。关于治疗EDD的干预措施和政策的研究问题,包括评估对卫生保健从业者进行运动医学重要性的教育和训练;确定在临床上识别和治疗EDD青少年的方法的有效性;开发敏感的、特效的、经济的方法以诊断青少年EDD;以及定制方法以促进本病诊疗的医疗保险赔付。如果未来研究不能优化EDD青少年的识别、治疗和管理方案,具有重大影响的生物医学、心理、经济和政治的新的卫生保健问题将会不断出现。  相似文献

The Ontario Council of University Libraries (OCUL) is a consortium of the twenty-one university libraries in Ontario, Canada. Since 1967, OCUL member institutions have worked together to share costs and workload through collective purchasing and licensing of information resources and more recently through the establishment of a shared digital infrastructure known as Scholars Portal. Under the auspices of OCUL, Ontario's university map librarians formed the OCUL Map Group in 1973 to seek opportunities to communicate and collaborate to improve the collections and services they offer their users. The opportunities provided by collaboration have ensured a greater capacity to manage evolving collections of geospatial data. The group has served as a community of practice, which has provided educational opportunities and facilitated collaborative problem solving through a listserv, conference calls, and face-to-face meetings. This collegial environment has also led to the completion of a number of projects, which have resulted in the creation of new technical infrastructures and strategies for sharing the workload of data management tasks. This paper discusses the role of collaboration in OCUL projects and offers some suggestions for others considering embarking on collaborations of their own.  相似文献
