The author traces the historical development of standards for library services prepared by the Joint Commission on Accreditation of Hospitals, emphasizing those elements of the present standards that auger well for the development of libraries in hospitals. Then examined are the role of librarians and new roles for libraries, stressing sound management practices that ensure continued development.  相似文献

By adolescence, men's participation and achievement in science exceeds women's. This article reports a case study that examined the beginnings of this gender differentiation during a naturally occurring academic activity that was designed to support and guide young children's interest in doing science. Data were collected during 2 successive years of a science fair for children in Grades 1–6 of a progressive private school. A total of 268 projects were characterized in terms of achievement and area of science. Parents provided information about the way children selected and created projects. In both years and in all grade levels, boys tended to choose to work in the physical sciences, and girls in the biological and social sciences. Peer collaborations were exclusively same sex. Achievement and parental involvement were not gender related. Factors are discussed that might lead to an early divergence of boys' and girls' interests in science within a context that promotes its exploration. © 1998 John Wiley & Sons, Inc.

The aim of this study was to examine participant and scheme characteristics in relation to access, uptake, and participation in a physical activity referral scheme (PARS) using a prospective population-based longitudinal design. Participants (n = 3762) were recruited over a 3-year period. Logistic regression analyses identified the factors associated with the outcomes of referral uptake, participation, and completion (> or = 80% attendance). Participant's age, sex, referral reason, referring health professional, and type of leisure provider were the independent variables. Based on binary logistic regression analysis (n = 2631), only primary referral reason was associated with the PARS coordinator making contact with the participants. In addition to the influence of referral reason, females were also more likely (odds ratio 1.250, 95% confidence interval 1.003-1.559, P = 0.047) to agree to be assigned to a leisure provider. Referral reason and referring health professional were associated with taking up a referral opportunity. Older participants (1.016, 1.010-1.023, P < 0.001) and males were more likely to complete the referral. In conclusion, the PARS format may be less appropriate for those more constrained by time (women, young adults) and those with certain referral reasons (overweight/obesity, mental health conditions). More appropriate targeting at the point of referral could improve participation rates by revealing or addressing barriers that might later result in dropout.  相似文献

The assumption that the first four cognitive levels of the taxonomy of educational objectives are arranged hierarchically and that this hierarchy is cummulative was evaluated. Mental ability and motivation scores were used to divide 144 high school biology students into six blocks. A 93-frame program in genetics was administered, and at the completion of the program the subjects took a 28-item posttest that had subscores for the cognitive levels of knowledge, comprehension, application, and analysis. Results indicated that no significant differences were found between knowledge and comprehension or application and analysis. A significant difference was found beyond the .0005 level, however, between comprehension and application. These results indicate that the cognitive processes at work at each level of the taxonomy may not be equitable, and that the previously mentioned assumptions are at least questionable.  相似文献

Walking is a safe, accessible and low cost activity, amenable to change and known to have great potential to increase physical activity levels in sedentary individuals. The objective of this study is to estimate the proportion of the 2009 adult population of England who would attain or exceed vigorous intensity activity (>70% maximum heart rate [HR(max)]) by walking at 3 mph. We conducted predictive impact modelling using participants' (n = 1741, aged 25-64 years) cardiovascular fitness data from treadmill walking tests. We combined this data with English population estimates adjusted for age and sex to estimate the numbers of individuals that would exceed 70% HR(max) (an intensity considered sufficient for fitness gains) when walking at 3 mph (4.8 km · h(-1)). We estimate 1.5 million men (95% confidence interval [CI] 0.9-2.2 million) (from 13.4 million corresponding to 11.6% (95% CI 7.0-16.2%)) and 3.9 million women (95% CI 3.0-4.8 million) (from 13.6 million corresponding to 28.6% (95% CI 22.0-35.1%)) in England aged 25-64 years would benefit from regularly walking at 3 mph. In total, a projected 5.4 million individuals (95% CI 3.9-6.9 million) aged 25-64 (from 26.97 million corresponding to 20.1% (95% CI 14.6-25.7%)) could benefit from walking at 3 mph. Our estimates suggest a considerable number of individuals in the English population could receive fitness and health benefits by walking regularly at 3 mph. Physical activity messages that promote walking at this speed may therefore have the potential to significantly impact national fitness levels and health in England.  相似文献

This article presents a mixed methods examination of teachers’ job beliefs in the Yukon Territory in northern Canada. In Study 1 we used questionnaires to examine job beliefs for 221 teachers from the Yukon and western Canada. Teachers’ self- and collective efficacy and workload stress were lower for Yukon teachers, but levels of overall stress and satisfaction were similar across settings. In Study 2 we conducted interviews to examine how geographical, community, and cultural factors were related to Yukon teachers’ job beliefs. Results showed that job stress and job satisfaction were influenced by physical and human geography, level of connection with the community, and by the community's cultural transitions. The findings highlight the influence of cultural and community factors on teachers’ working lives.  相似文献

This article highlights the transformative contributions of Mary Monroe Atwater to the field of science education. Influenced by worldviews shaped by a segregated macro-society and the privileges of a micro-society, Mary stood against oppression in the early years of her academic career by desegregating academic settings and being the first and only African American in varied arenas for many years. As an aspiring academic, Mary challenged dominant paradigms and as an activist academic, she changed the landscape of science education. She broadened the knowledge base through scholarship and praxis and diversified the science education community through personal and professional efforts that were pioneering in nature.

This paper reports on outcomes from a White Rose Centre for Enterprise funded project Managing Innovation in the Digital Economy. This project aims to incorporate learning for enterprise into undergraduate and postgraduate curricula in information management and information systems. The paper presents results from a survey distributed to postgraduate information management and information systems students following completion of a module in E‐Business and E‐Commerce delivered by the Department of Information Studies at the University of Sheffield. The findings suggest that differences in levels of prior knowledge of business studies and in cultural background can impact on students’ acquisition of domain knowledge and intellectual and information research skills during collaborative development of a business plan. Implications of the results for web‐based instruction are addressed, by identifying teaching and learning strategies that support differential treatment of learners in terms of content and process. It is concluded that empirical investigation of individual differences within a student body can inform more effective methods for information systems and information management graduates to learn about and for entrepreneurship.  相似文献
