ABSTRACTThis study explores the idea of creating a knowledge base from shared online accounts to use in training librarians who perform distance reference services. Through a survey, follow-up interviews and a case study, the investigators explored current and potential use of shared online accounts as training tools. This study revealed that the participants viewed the concept positively, but many encountered barriers to effectively employing a local knowledge base as a training tool. 相似文献

Within the Canadian context, the physical activity levels of children and youth in the after school time period has become a source of public health concern. We argue that this concern is informed by broader public health crises, in particular the ‘global obesity epidemic’ and the closely related ‘global pandemic of physical inactivity', and that these so-called ‘crises’ operate as part of a discursive regime that serves to justify after school interventions aimed at increasing the physical activity practices of children and youth. Although the objectives of such interventions are seemingly well intentioned, we suggest that such interventions nonetheless harbor difficult to discern, but potentially pernicious consequences, for the communities in which they are implemented. We focus our attention on the place-specific effects of one Public Health Agency of Canada-funded after school physical activity intervention – After the School Bell Rings (ASBR) – that was implemented in the mostly Indigenous, northern community of Placid, Manitoba. Based on a critical analysis of the ASBR program itself, along with interviews and focus groups with children, parents and recreation providers (n?=?10) from the community of Placid, we contend that the ASBR serves to govern Indigenous recreation at a distance. We argue that when implemented in the place-specific context of Placid, the ASBR functions as part of a broader governmental assemblage composed of loosely connected discourses, institutions, socio-structural conditions and individuals that, when assembled, ultimately serve to govern geographically and culturally distinct communities. We conclude by suggesting that the objectives of broad-based health interventions, such as the goal of increasing after school physical activity levels, should not be universally implemented across diverse locales, but need to account for the diverse, place-specific priorities and needs of the communities into which they are implemented. 相似文献

In this work, we describe a simple coarse-grained model of a barbell that can be used to determine the qualitative role of bar bend during a jerk. In simulations of this model, we observed a narrow time window during which the lifter can leverage the elasticity of the bar in order to lift the weight to a maximal height. This time window shifted to later times as the weight was increased. In addition, we found that the optimal time to initiate the drive was strongly correlated with the time at which the bar had reached a maximum upward velocity after recoiling. By isolating the effect of the bar, we obtained a generalized strategy for lifting heavy weight in the jerk. 相似文献

Abstract The influence of the Cardan rotation sequence on the orientation angles for joints is well known but has not been explored for dynamic sports movements. The purpose of this study is to establish the influence of Cardan rotation sequence on the orientation angles of the ankle, knee, and hip of the support leg and pelvis during dynamic sports movements, typified by a maximal instep kick in soccer. We found that: (a) the X (flexion/extension) axis rotations provide data that are robust for any sequence used other than the YXZ sequence, although the Y (abduction/adduction) and Z (internal/external) axes rotations are variable in both shape and offset magnitude; (b) the preferred rotation sequence is either XYZ or XZY for dynamic sports movements, although for the soccer kick the XYZ rotation sequence has been widely used and so this is recommended as a standard; and (c) most uncertainties exist in the Y and Z axes and are most apparent at the beginning of the movement. Where uncertainty exists in identifying Y and Z axes orientations, the integrated angular velocity may be considered as an alternative to determine the relative changes in segment orientation. 相似文献

Numerous classroom-based interventions have aimed to improve sexual health outcomes for young people, yet few have shown strong, lasting effects. Ecological approaches that address multiple levels of a young person’s environment offer largely untapped potential to positively change sexual behaviour. This paper presents results of a cluster-randomised trial of a multicomponent sexuality education intervention that integrated a classroom curriculum, parent education workshops and materials, peer advocate programme, and sexual health services at 10 urban high schools. An implementation evaluation, employing quantitative and qualitative instruments, was conducted to examine whether the individual components of the intervention were delivered as planned and how they were received by the target populations. Multilevel modelling was used to evaluate the effect of the multicomponent intervention on outcomes at one-year follow-up. Results showed that the intervention components were successfully implemented with and well received by target populations. Students receiving the multicomponent intervention reported greater increases in the use of sexual health services (odds ratio [OR] = 1.73, 95% CI = 1.09–2.75) and the likelihood of carrying a condom (OR = 2.71, 95% CI = 1.44–5.09) relative to those receiving a control condition. No effects were found for other behaviours, possibly due to low prevalence of sexual activity in the sample and the small number of schools randomised. 相似文献

In response to increased student assessment and accountability concerns, colleges and universities have been called on to increase their efforts to improve the retention rates of an increasingly diverse student body. This article outlines a synergistic strategy for promoting minority student persistence through faculty renewal efforts that encourage faculty to question their cultural beliefs and academic values concerning the teaching and learning enterprise.Dr. Kay F. Norman is currently with Delaware State University where she is Director of the Center for Excellence in Teaching. She also teaches graduate courses in Educational Assessment and Special Education Administration and Supervision. She holds an Ed.D. in Higher Education Administration with emphasis in Student Services from Texas Southern University. Her research interests are in student retention, assessment, and effective teaching. James Norman, Ph.D., is an Associate Professor of Education at Delaware State University's School of Education. He is a graduate of Ohio State University. Dr. Norman's research interest include special education monitoring and compliance issues, and behavioral management systems. 相似文献

This study was designed to assess the impact of taking a high quality picture book home from school daily on the at-home reading behaviors of young children and/or family members from middle and low SES backgrounds. Eighty children representing two study groups (treatment & no-treatment comparison) and two socioeconomic groups (Head Start & middle-class) composed the study sample. Treatment children selected picture books at school daily to take home over a 12-week period. Child and family picture book reading behaviors were assessed by weekly random telephone surveys. Findings indicate that taking a picture book home daily more than doubled the number of books read at home for both middle-class and Head Start treatment children over their no-treatment comparison counterparts and significantly increased the amount of time Head Start treatment children were involved in reading each day. The practicality of making high quality picture books available for preschool children to take home and the implications of increased at-home reading behaviors are discussed. 相似文献

The Student Counselling Needs Scale (SCNS) was administered to 867 participants recruited from high schools in Kenya. The data were analyzed using exploratory factor analysis yielding five factors: human relationships, career development, self development, social values, and learning skills were assessed. The findings highlighted the importance of using assessment instruments to identify students’ counselling needs in Kenya. 相似文献
