Dissecting through Barriers: A Follow-up Study on the Long-Term Effects of Interprofessional Education in a Dissection Course with Healthcare Professional Students     

Yu Hang Zheng  Andrew Palombella  Jenn Salfi  Bruce Wainman 《Anatomical sciences education》2019,12(1):52-60

Several studies have shown significant improvements in the attitudes and perceptions of healthcare professional students toward interprofessional education (IPE) immediately following intervention with IPE courses. However, there remains little evidence on the lasting effects of IPE courses and the long-term influences of these IPE experiences are poorly documented. The purpose of this study is to assess the long-term effects of an intensive, ten-week interprofessional gross anatomy dissection course at McMaster University. Attitudes and perceptions of past participants towards interprofessional learning were evaluated, now that they have started working with other healthcare professionals outside of the IPE course setting. Thirty-four past participants who have clinical experience working in interprofessional settings or are currently working in the healthcare field completed a follow-up questionnaire consisting of a modified Readiness for Interprofessional Learning Scale (RIPLS) and open-ended questions. Quantitative analysis revealed a significant decrease in their attitude towards teamwork and collaboration and respect for other health professions, but a significant improvement in their understanding of roles and responsibilities compared to their results immediately after the IPE intervention. Qualitative analysis of open-ended questions revealed several themes such as developing interprofessional competencies, developing relationships, and remembering the strengths of the IPE dissection course. The results of this study indicate that the IPE experience in anatomy was highly valued by the students and that past participants maintain a clear understanding of their scope of practice, but the reality of clinical practice may have eroded gains made in the program.

Where are we now? A review of research on the history of women's soccer in Ireland     

Helena Byrne 《Sport in History》2019,39(2):166-186

ABSTRACT

It is a common fact that women's sport and leisure history, especially in male dominated spheres, and more specifically football, have been ignored by many academics. However, in recent years there have been major developments in digital technology that have changed the nature of the type of research that can be done. Access to tools to facilitate field research are relatively cheap and with the high volume of digitisation projects that have taken place over the last few years as well as the increasing number of born digital resources that have been published, there are new opportunities. In relation to women's soccer in Ireland, this paper asks the question – where are we now? The argument will review the current literature on this subject and outline potential approaches for future research.  相似文献   

High-resolution mapping of brain vasculature and its impairment in the hippocampus of Alzheimer's disease mice

Accumulating evidence indicates the critical importance of cerebrovascular dysfunction in the pathogenesis of Alzheimer''s disease (AD). However, systematic comparative studies on the precise brain vasculature of wild-type and AD model mice are still rare. Using an image-optimization method for analysing Micro-Optical Sectioning Tomography (MOST) data, we generated cross-scale whole-brain 3D atlases that cover the entire vascular system from large vessels down to smallest capillaries at submicron resolution, for both wild-type mice and a transgenic (APP/PS1) mouse model of AD. In addition to distinct vascular patterns in different brain regions, we found that the main vessels of the molecular layer of the hippocampal dentate gyrus (DG-ml) undergo abrupt changes in both diameter and branch angle, spreading a unique comb-like pattern of capillaries. By using a quantitative analysis workflow, we identified in the hippocampus of AD mice an overall reduction of the mean vascular diameter, volume fraction and branch angle, with most significant impairment in the DG-ml. In addition, virtual endoscopy revealed irregular morphological features in the vessel lumen of the AD mice, potentially contributing to the impairment of blood flow. Our results demonstrate the capability of high-resolution cross-scale evaluation of brain vasculature and underscore the importance of studying hippocampal microcirculation for understanding AD pathogenesis.  相似文献   

Using football cultures as a vehicle to improve mental health in men: the case of the Redcar and cleveland boot room     

Kevin Dixon  Dave Belshaw  Paul Johnson  Darren Flynn 《Sport in Society》2019,22(7):1258-1274

This paper sets out to appraise (from the perspective of members) the impact of a localized, football-based mental health intervention. Commissioned in late 2015, the ‘Redcar and Cleveland Boot Room (BR)’ was implemented in response to mass redundancy in the local area, coupled with regional suicide rates in men that exceed the national average. Interactive discussions with BR members revealed that: (a) the language of football and shared identity were important for initiating and sustaining engagement in the BR; (b) peer-support and mentoring combined with member-led activities were active ingredients of the BR and (c) that the BR was an effective vehicle for building mental health resilience. This evaluation adds to the evidence base on the value of football as a context to engage adult males in community-based interventions targeting mental health resilience.  相似文献   

Creativity development in preschoolers: The effects of children’s museum visits and other education environment factors     

《Studies in Educational Evaluation》2020

As one of the potential contextual factors for creativity development, children’s museum has been introduced to China from the western world in recent years, with the aim to offer a new informal educational environment to enhance children’s creativity. Based on experimental data for two groups of 4-year-old preschoolers (218 for the family mode and 202 for the preschool mode) from Beijing with an appropriately one-year long intervention (September 2017 to July 2018), this study examines the effect of regular visits to a children’s museum and other education environmental factors on young children’s creativity measured by Torrance’s Thinking Creatively in Action and Movement (TCAM) test. Results indicate that in terms of family visit, compared to the control group, the intervention that offers 18 times free tickets to visit a children’s museum significantly improved the experiment group’s originality (a sub-measure of creativity) by an additional 34.51 %. A beneficial effect of this intervention was also found in improving children’s fluency from the sample of preschool group visit (46.80 %). In addition, family education environment factors such as public preschool attendance, frequency of visits to science museums, and the degree of parents’ latitude were also found to positively affect creativity. Children’s personal features such as sex and geographic location of the family are also found to be related with children’s creativity.  相似文献

Ethno-national boundaries in the construction of “dirty-work” occupational identity: The case of nursing care workers in diversified workplaces     

《Int J Intercult Relat》2020

Diversified domains, such as workplaces, are suitable social fields for the study of ethnic identities, because identities are constructed through comparison and negation, that is, by identifying what or who the “other” is. In the present study I explore the talk of hands-on nursing care work, a stigmatized occupational field, to illuminate ethnic identities and the strategic boundary work that care workers conduct. The study is based on 14 months of field work and 51 interviews and observations at two Israeli geriatric wards with highly diverse staff. I show that actors negotiate their care worker identity by the opposite strategies of making and unmaking ethno-national boundaries. The first strategy denies and erases ethno-national boundaries by stressing universal professional values and individual virtues; the second one demarcates boundaries between ethno-national groups, using perceived cultural differences. The discussion addresses these antithetical evaluation frameworks in relation to theories of boundary making and unmaking.  相似文献   

新时代我国体育消费力提升研究     

孙威  王晓辉 《沈阳体育学院学报》2020,(3):49-55

当前我国体育消费力较弱,亟需通过研究提升体育消费力。运用文献资料、逻辑分析等方法,依据马克思消费力理论提出并解析了体育消费力的4要素及其现实情况:体育供给不到位导致消费品难以满足需求、居民收入不平衡限制消费者的支付能力、体育环境不规范阻滞良好消费氛围的形成、体育消费者不成熟拉低消费力的整体水平。体育消费力提升路径:以供给侧结构性改革为主线有效优化体育供给力,以拓宽人民增收渠道为手段动态平衡居民可支配收入,以完善市场化引导监督机制为动力合理规范体育社会环境,以强化消费者要素整合能力为抓手全面提升体育消费者成熟度。  相似文献
