The Unintentional Effects on Body Donation Programs of a Competency-Based Curriculum in Postgraduate Medical Education     

Geoffroy P.J.C. Noël  Joseph Dubé  Gabriel Venne 《Anatomical sciences education》2021,14(5):675-681

As medical programs place increasing importance on competency-based training and surgical simulations for residents, anatomy laboratories, and body donation programs find themselves in a position of adapting to changing demands. To better assess the demand for “life-like” cadaveric specimens and evaluate the possible impacts that competency-based medical education could have upon the body donation program of McGill University, Canada, the authors tracked, over the course of the last 10 years, the number of soft-embalmed specimens, along with the number of teaching sessions and the residents enrolled in competency-based programs that are using cadaveric material. The results reveal that the number of soft-embalmed specimens used within residency training increased from 5 in 2009 to 35 in 2019, representing an increase from 6% of bodies to 36.5% of the total number of body donors embalmed in this institution. Correspondingly, the number of annual teaching sessions for residents increased from 19 in 2012 to 116 in 2019. These increases in teaching are correlated with increasing number of residents enrolled in competency-based programs over the last 3 years (Pearson r ranging from 0.9705 to 0.9903, and R² ranging from 0.9418 to 0.9808). Those results suggest that the new skill-centered curricula which require residents to perform specific tasks within realistic settings, exhibit a growing demand for “life-like” cadaveric specimens. Institutions’ body donation programs must, therefore, adapt to those greater need for cadaveric specimens, which presents many challenges, ranging from the logistical to the ethical.  相似文献   

The resilience of scientific publication: From elite ancient academies to open access     

Jonathan J. Mallett 《Learned Publishing》2021,34(1):49-56

• Scientific publication has been a key part of the scientific method since the inception of Philosophical Transactions in 1665.
• The scientific publications industry has grown exponentially along with science, incorporating technological innovations along the way, and adapting journal processes and practices to changing needs of science as it matured.
• Of all the technological innovations over more than 300 years, the move to online journals may be the most significant, making open access to content practical for the first time.
• The open‐access movement is disrupting the economics of journal publishing, which is hoped will make the industry more competitive: the ability of the publications industry to adapt to open access will be a measure of its resilience.
• The demand for articles published in reputable journals continues to grow as readers trust the credibility of peer reviewed journal articles, and good authors value the prestige of publishing in the best journals.
• It is difficult to predict what new functionalities may be included in articles of the future or what additional services publishers and editors will provide, but there is every reason to believe that scientific journal articles are here to stay.

指向武术核心素养的中小学武术有效教学策略与方法设计     

柴广新  孙有平 《武汉体育学院学报》2020,54(4):87-92

为了有效促进学生武术核心素养的培育,针对我国武术教学中存在套路内容“繁难”、教法单一、重“形”轻“击”、重知识灌输,轻自主性培养、重教师的“教”,轻学生的“学”“学生不喜欢武术课”等一系列问题,提出了有效促进武术认知、武术运动能力、武术人格培育的原则,基于此原则,对“化难为易”策略、“化浅为深”策略、“化无趣为有趣”策略、“化技术为实践”策略、“知新温故”等策略进行了具体探索性设计,并对上述策略的具体实施方法进行了阐述,为中小学武术教学改革提供现实指导。  相似文献

视力康复背景下体育锻炼与儿童动态视力关系研究及启示          下载免费PDF全文

潘景玲  蔡赓  殷荣宾  孙雷  王国祥 《体育科研》2019,(1):90-95

目的：探讨动态视力在不同类型体育项目间的发展特征，为体育锻炼改善视力的应用研究提供依据。方法：选取6~10岁无专门体育训练经历的在校学生和参加足球、乒乓球、跆拳道、空手道、游泳、体操等项目的俱乐部或体校学生，共603名。使用动态视力检测仪和标准对数视力灯箱测量动态视力和静态视力。计算动静比（动态视力/静态视力），并将其作为衡量动态视力发展水平的指标。结果：6~7岁是动态视力发展的敏感期（P＜0.05），8岁、10岁男性儿童的动静比高于女性儿童，且差异有统计学意义（P＜0.05）。校外体育练习组的动静比高于普通在校学生组（P＜0.05），开放性运动项目的动静比高于闭锁性运动项目（P＜0.05）。结论：参加体育锻炼对动态视力的发展有积极的影响，且不同运动项目的影响效果不同。  相似文献   

Cultured meat and cowless milk: on making markets for animal-free food     

Michael J. Mouat 《Journal of Cultural Economy》2018,11(4):315-329

According to its proponents, animal-free animal food products, such as cultured meat and synthetic cow’s milk, have the potential to overcome various environmental, health and ethical challenges that have emerged around global animal product consumption and the industrial agriculture that is needed to support it. Apart from the myriad of technical problems making animal-free food products, critics have pointed out the blurry ontological status of the food and the ethical challenges therein, and have questioned the veracity of the various promissory narratives being produced. This paper considers animal-free food from a social studies of economies and markets (SSEM) perspective. As a market that currently mostly only exists in potential, an SSEM perspective can reveal the various social and material relations that comprise the (bio)capital formation that will underpin any market-to-be, an aspect of markets that are often invisible once markets are up and running. Moreover, this perspective details the intimate role markets have in establishing the ethical and ontological aspects of animal-free foods in a political economy shaped by neoliberalisation and financialisation.  相似文献

运动因子在心血管功能中的调控作用及相关机制研究进展     

于凤至  孙朋  刘淑卉 《中国体育科技》2020,(5):48-58

心血管疾病(cardiovascular disease,CVD)是包括动脉粥样硬化、心力衰竭、心脏缺血后再灌注损伤和心肌梗死等血管和心脏的复杂病症。血管内皮细胞、平滑肌细胞和心肌细胞生理功能障碍是诱发CVD的关键因素。研究表明,运动能够对心脏和动脉的形态、功能起到积极的调控作用,可作为CVD非药物疗法的重要手段之一。运动可通过调控多种运动因子的表达水平,如肌肉分泌的Fstl1、Irisin和MSTN,脂肪分泌的Omentin、Apelin、CTRP3和CTRP9,肝脏分泌的FGF21、ANGPTL3和ANGPTL4等,进而调控血管内皮细胞、平滑肌细胞和心肌细胞的分化、增殖和凋亡,从而发挥其防治CVD作用。本文试图梳理肌肉、脂肪和肝脏分泌的运动因子与调控心脏和动脉功能之间的相关信号通路及其机制,为运动干预防治CVD提供新的思路。  相似文献
