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   

Implementing an institution-wide electronic lab notebook initiative     

Erin D. Foster  Elizabeth C. Whipple  Gabriel R. Rios 《Journal of the Medical Library Association》2022,110(2):222

Background:To strengthen institutional research data management practices, the Indiana University School of Medicine (IUSM) licensed an electronic lab notebook (ELN) to improve the organization, security, and shareability of information and data generated by the school''s researchers. The Ruth Lilly Medical Library led implementation on behalf of the IUSM''s Office of Research Affairs.Case Presentation:This article describes the pilot and full-scale implementation of an ELN at IUSM. The initial pilot of the ELN in late 2018 involved fifteen research labs with access expanded in 2019 to all academic medical school constituents. The Ruth Lilly Medical Library supports researchers using the electronic lab notebook by (1) delivering trainings that cover strategies for adopting an ELN and a hands-on demo of the licensed ELN, (2) providing one-on-one consults with research labs or groups as needed, and (3) developing best practice guidance and template notebooks to assist in adoption of the ELN. The library also communicates availability of the ELN to faculty, students, and staff through presentations delivered at department meetings and write-ups in the institution''s newsletter as appropriate.Conclusion:As of August 2021, there are 829 users at IUSM. Ongoing challenges include determining what support to offer beyond the existing training, sustaining adoption of the ELN within research labs, and defining “successful” adoption at the institution level. By leading the development of this service, the library is more strongly integrated and visible in the research activities of the institution, particularly as related to information and data management.  相似文献   

Estimates of the number of people in England who attain or exceed vigorous intensity exercise by walking at 3 mph     

Kelly P  Murphy M  Oja P  Murtagh EM  Foster C 《Journal of sports sciences》2011,29(15):1629-1634

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   

Teaching in the Yukon: Exploring teachers’ efficacy beliefs,stress, and job satisfaction in a remote setting     

Robert M. Klassen  Rosemary Y. Foster  Sukaina Rajani  Carley Bowman 《International Journal of Educational Research》2009,48(6):381-394

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   

Individual differences in learning entrepreneurship and their implications for web-based instruction in e-business and e-commerce     

Jonathan Foster  Angela Lin 《British journal of educational technology : journal of the Council for Educational Technology》2003,34(4):455-465

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   

Images in mirrors: Recollections,alternative explanations and modes of cognitive functioning     

Dr. Brian Jones  Professor Kevin Collis  Dr. Jane Watson  Miss Kimberley Foster  Dr. Sharon Fraser 《Research in Science Education》1994,24(1):191-200

Students' conceptions of how objects are seen directly, and in mirrors, were explored in an analysis of their written and drawn responses to common visual phenomena depicted in cartoons with brief text. Students in Grades K-10 (n=214) completed a questionnaire and some were interviewed. Evidence was sought to support an hypothesis for increasingly sophisticated responses related to the concepts of sight, light, reflection and image. The developmental model used in this analysis was the updated SOLO Taxonomy (Biggs & Collis, 1991; Collis & Biggs 1991). It appears from the results that different modes of functioning can interfere to produce factually incorrect recollections of experience particularly in the age group 7 to 13 years approximately. Also, this is associated with the common spurious conception that mirrors have a lateral inversion property. Explanations involving light were extremely rare and its role related to the production of an image ‘in the mirror’ but not to the perception of an image in the eyes. Specializations: science education, students' understandings of phenomena in science. Specializations: cognitive development, evaluation, mathematics and science education. Specializations: mathematics education, students' understanding of chance and data concepts.  相似文献

Developing mathematical fluency: comparing exercises and rich tasks     

Colin Foster 《Educational Studies in Mathematics》2018,97(2):121-141

Achieving fluency in important mathematical procedures is fundamental to students’ mathematical development. The usual way to develop procedural fluency is to practise repetitive exercises, but is this the only effective way? This paper reports three quasi-experimental studies carried out in a total of 11 secondary schools involving altogether 528 students aged 12–15. In each study, parallel classes were taught the same mathematical procedure before one class undertook traditional exercises while the other worked on a “mathematical etude” (Foster International Journal of Mathematical Education in Science and Technology, 44(5), 765–774, 2013b), designed to be a richer task involving extensive opportunities for practice of the relevant procedure. Bayesian t tests on the gain scores between pre- and post-tests in each study provided evidence of no difference between the two conditions. A Bayesian meta-analysis of the three studies gave a combined Bayes factor of 5.83, constituting “substantial” evidence (Jeffreys, 1961) in favour of the null hypothesis that etudes and exercises were equally effective, relative to the alternative hypothesis that they were not. These data support the conclusion that the mathematical etudes trialled are comparable to traditional exercises in their effects on procedural fluency. This could make etudes a viable alternative to exercises, since they offer the possibility of richer, more creative problem-solving activity, with comparable effectiveness in developing procedural fluency.  相似文献   

Infants' perception of object trajectories     

Johnson SP  Bremner JG  Slater A  Mason U  Foster K  Cheshire A 《Child development》2003,74(1):94-108

Filling in the gaps in what humans see is a fundamental perceptual skill, but little is known about the developmental origins of occlusion perception. Three experiments were conducted with infants between 2 and 6 months of age to investigate perception of the continuity of an object trajectory that was briefly occluded. The pattern of results across experiments provided little evidence of veridical responses to trajectory occlusion in the youngest infants, but by 6 months, perceptual completion was more robust. Four-month-olds' responses indicated that they perceived continuity under a short duration of occlusion, but when the object was out of sight for a longer interval, they appeared to perceive the trajectory as discontinuous. These results suggest that perceptual completion of a simple object trajectory (and, by logical necessity, veridical object perception) is not functional at birth but emerges across the first several months after onset of visual experience.  相似文献   

Integrating hearing and deaf students on a college campus. Successes and barriers as perceived by hearing students     

P M Brown  S B Foster 《American annals of the deaf》1991,136(1):21-27

This study had two purposes: (1) to learn how hearing students in a mainstream college setting perceive deaf students as classmates, and (2) to discover how those perceptions influence the integration of deaf and hearing students on campus. Thirty full-time students at the Rochester Institute of Technology in Rochester, New York, were interviewed using in-depth, open-ended interview strategies. It was found that even in this setting, designed expressly to integrate deaf and hearing students, full integration did not occur. Deaf students were successfully placed on the campus with hearing students for educational purposes; however, social integration did not occur.  相似文献
