Formal body bequest program in Nigerian medical schools: When do we start?     

Akinola OB 《Anatomical sciences education》2011,4(4):239-242

Human body dissection is a prerequisite for the training of health professionals and the conduct of medical research. However, most Nigerian medical schools experience difficulty obtaining an adequate and regular supply of human tissue. Presently, the major source of anatomical material comes from unclaimed bodies collected from hospital mortuaries. However, one sure way to ensure a regular supply of bodies for anatomical dissection is to establish a whole body bequest program among the departments of anatomy in Nigerian medical schools. If such a program were to be supported by an appropriate legislative act of parliament, the supply of acceptable cadavers for anatomical teaching and research would be substantially increased. The author advocates for establishing a whole body bequest program among Nigerian medical schools.  相似文献   

Critical psychologies of disability: boundaries,borders and bodies in the lives of disabled children     

Dan Goodley  Katherine Runswick Cole 《Emotional and Behavioural Difficulties》2015,20(1):51-63

Attending to the ways in which bodies and subjectivities are constituted in social environments is not simply a concern of social geographers but an emerging interest in critical psychology, childhood and disability studies. Boundaries and borders are nothing if not the different relational and durational articulations of bodies and spaces. These entangled boundaries include borders between parent and child; culture and body; school, family and child. Through analysing the ways in which these borderlines are continually re-composed and re-constituted, we are able to reveal their relational and embodied articulations. In previous works, we have explored the ways in which disabled children disrupt normative orders associated with school, family and community. In this paper, we take up the concepts of boundaries and borders to explore their relational and embodied articulations with specific reference to stories collected as part of an ESRC project entitled ‘Does every child matter, Post-Blair: the interconnections of disabled childhoods’. We ask, how do disabled children negotiate space in their lives? In what ways do they challenge space through their borders and boundaries with others? How can we re-imagine, re-think and differently practice – that is revolutionise – key borders and boundaries of education in ways that affirm the lives of disabled children? We address these questions through reference to the narrative from the Derbyshire family, with particular focus on Hannah and her mother Linda, which we argue allow us to consider the ways in which disabled childhoods can be understood and reimagined. We explore two analytical considerations; ‘Being disabled: being mugged’ and ‘Becoming enabled: teacups, saucers and communities’.  相似文献

Action theory and the value of sport     

Jon Pike 《体育哲学杂志》2019,46(1):14-29

I present a corrective to the formalist and conventionalist down-playing of physical actions in the understanding of the value of sport. I give a necessarily brief account of the Causal Theory of Action (CTA) and its implications for the normativity of actions. I show that the CTA has limitations, particularly in the case of failed or incomplete actions, and I show that failed or incomplete actions are constitutive of sport. This allows me to open up the space for another model, drawn from Aristotle, for failed or incomplete actions, conceived of as ‘doables.’ This avoids some of the problems of the CTA. I explain the importance of difficult but doable actions, at which athletes often fail, and suggest that this establishes pro tanto value. Finally, I claim that this account of the actions that are constitutive of sport deepens our understanding of the value of sport as a whole.  相似文献   

国际体育仲裁院对体育组织规则与决定的审查--以平昌冬奥会俄罗斯运动员参赛资格纠纷为例     

李睿智  郭树理 《成都体育学院学报》2020,(2):49-56

震惊体坛的俄罗斯运动员大规模使用兴奋剂事件引发了一系列后果,国际奥委会对俄罗斯奥委会实施禁赛,俄罗斯运动员必须经由国际奥委会特别设立的邀请程序方得参加平昌冬奥会。体育仲裁院平昌冬奥会特别仲裁处经审查认定该程序具有法律依据且实施得当。然而,该程序实际设立了一项特别参赛规则:存在兴奋剂违纪记录的俄罗斯运动员不得参加平昌冬奥会。该规则有违反"一事不再罚"原则之嫌,但特别仲裁处由于未能充分行使抽象审查的权力,未能为俄罗斯运动员的权利提供适当救济。体育组织应审慎行使规则和决定的自治权,充分考量规则和决定的合法性、合理性。另外,我国现有针对体育组织决定和规则的外部审查机制存在主体单一化、缺乏独立性的缺陷,不利于运动员权益的保障,应尽快建立具有可操作性的体育仲裁制度。  相似文献   

Governing bodies of sport as knowledge brokers in Sport-for-All communities of practice     

《Sport Management Review》2019,22(5):584-599

Delivering Sport-for-All is a major challenge for sport organizations and policy-makers worldwide. Sport-for-All is a practical activity and a knowledge intensive field, characterized by dispersed knowledge creation and sharing processes involving numerous agencies, professionals and volunteers; in other words, it is a community of practice. Communities of practice are vehicles that allow knowledge sharing and creation in intensive and dispersed settings. Learning in communities is enhanced by knowledge brokers, a role typically assumed by governing bodies of sport as part of their formal mandates. In this study, the authors use a community of practice lens to look at Sport-for-All. The authors collected and analyzed data on Sport-for-All communities on the regional (Flanders), national (Australia and England), and international (Sport and Development) level by interviewing key people in each of the communities, and by interrogating virtual knowledge repositories (websites) and public web-based data. Results indicated the existence of Sport-for-All communities of practice with governing bodies of sport acting as brokers in those communities for sharing knowledge, exploration of new ideas, and knowledge creation. However, governing bodies of sport are not strategically exploiting the full potential of online tools to enhance the communities. They ought to focus on supporting the communities by taking a more strategic approach and using new media tools, and let the community of practice standards emerge instead of determining them.  相似文献   

Confucian Ethics on the Commercial Use of Human Bodies and Body Parts: Yi (Righteousness) or/and Li (Profit)?     

Jing-Bao Nie  David Gareth Jones 《Anatomical sciences education》2019,12(4):444-453

In China as elsewhere in the world, human bodies and body parts have long been used for a wide range of medical and non-medical purposes. In recent decades, China has played a considerable role in some of the public exhibitions of plastinated bodies and body parts, and the commercial trade in organ donations. These contemporary developments have raised numerous challenging ethical and governance questions. In spite of the growing role of China in these, there have been few studies devoted to Chinese ethical thinking that might govern its policies on the use of human bodies and body parts, and in particular on the issue of commercialization. The present study is an attempt to bridge this gap, and concludes that Confucian thinking stresses the primacy of righteousness over profits and utilities. This conclusion is reached directly by drawing on Confucian ethical responses to the peculiar practice of using human body parts, such as placenta and flesh, as drugs in traditional Chinese medicine in imperial China and what has been called “yili zhibian,” the major Confucian discourse on yi (righteousness or justice) and li (profit or interest) in its long history. The principle of prioritizing righteousness over profit leads to a general moral opposition to the commodification of human bodies and body parts. While Confucianism may not place an absolute prohibition on any such use, it does require that any commercial uses are made subject to the fundamental moral principles, such as righteousness, as well as adequate ethical governance procedures.  相似文献

对比有无磁场条件下铁磁性材料摩擦副的摩擦学性能,发现直流磁场的存在显著改善了铁磁性材料摩擦副的摩擦学性能。其主要原因是磁场的存在使磨屑保持摩擦副之间,从而铁磁性材料摩擦副的两体摩擦转变为摩擦副、磨屑之间的三体摩擦;同时,磁场的存在提高了氧化磨损在磨损中的比例。  相似文献   

Isotropic dual p-surface area measure     

俞武扬 《上海大学学报(英文版)》2010,14(6):437-441

It is shown that a convex body has minimal dual p-surface area among its affine transformations of the same volume if and only if its dual p-surface area measure is isotropic. A double-sided estimate for the （n-1）-dimensional volume of the intersection of a dual p-surface isotropic convex body in terms of its affine invariant dual p-surface quantity is given. Furthermore, the dual p-isopermetric inequality is obtained.  相似文献
