Doping testing is a key component enforced by anti-doping authorities to detect and deter doping in sport. Policy is developed to protect athletes’ right to participate in doping-free sport; and testing is a key tool to secure this right. Accordingly, athletes’ responses to anti-doping efforts are important. This article explores how the International Standards for Testing, which face different interpretations and challenges when policy is implemented, are perceived by elite athletes. Particularly, this article aims to investigate how elite athletes perceive the functioning of the testing system (i.e., the efforts of stakeholders involved in testing) in their own sport both nationally and worldwide. Moreover, it seeks to identify whether specific factors such as previous experience of testing and perceived proximity of doping have an impact on athletes’ perceptions of the testing system. The study comprises a web-based questionnaire (N = 645; response rate 43%) and uses qualitative findings to elaborate on and explain quantitative results. Results showed that two-thirds of the athletes reported the national testing programme in their sport to be appropriate. A majority of the athletes who had an opinion on the subject regarded testing programmes in some countries as not extensive enough or believed that in certain countries doping control was downgraded to win medals. Past experience of testing seemed to have a positive influence on trust in the concrete measures; however, if athletes experienced flaws during the control procedures, this could increase distrust and cause worry. The proximity of doping in an athlete's sport influenced the athlete's perception of the testing system. Particularly, athletes who need the testing system to be effective and to function well across the world show greater distrust of or dissatisfaction with the current testing system. The athletes’ diverging views indicate that contemporary anti-doping policy is simultaneously met with support, (dis)trust and frustration. By integrating the views and experiences of Danish elite athletes, this study confirms that the current testing system is confronted with obstacles, and it contributes knowledge about some of the challenges WADA faces when policy is implemented. Implications of results and recommendations for anti-doping authorities are outlined in the paper.  相似文献

Our comments focus on the ACMCode of Ethics and situate the Code within ageneral ethical decision-making process tospecify the five steps which logically precedehuman action in ethical matters and determinethat action, and the individual differencetraits in these five steps which bear upon theresolution of an ethical problem and lead tomorally responsible action. Our main purpose isto present a cognitive moral processing modelwhich computing professionals can use to betterunderstand their professional rights andduties. It is clear that the Code providessubstantial guidance in the areas ofintellectual property rights, unauthorizedentry into computing systems, and privacy. Inother areas, such as obscenity onbulletin-board systems, the Code is silent. Aninteractive software program which allows theuser to see the ways in which the Code isintegrated and instructive in the six-stepmoral decision-making process is accessible viathe internet. Our secondary purpose is toreformulate the Code as a set of questionswhich allow the computing professional to seepractices which diminish the human person asunethical and those which enhance the humanperson as ethical.  相似文献

Students’ ability to build knowledge, and transfer it within and between contexts is crucial to cumulative learning and to academic success. This has long been a concern of higher education research and practice. A central part of this concern for educators is creating the conditions that enable their students' deep learning, as this is an area of significant struggle for many students. Legitimation Code Theory, in particular the dimension of Semantics, is proving useful in examining the kinds of conditions that may be necessary for students to build disciplinary knowledge cumulatively over time. Using illustrative data from one case study, this paper suggests that the conceptual tools offered by Semantics can provide academic lecturers and academic development staff with a set of conceptual and analytical tools which can enable them to ‘see’ and understand the ways in which knowledge can be cumulatively acquired and used, as well as the possible gaps between what they are teaching and what their students may be learning. The hope is that these new insights will provide new directions for change in teaching and learning where these may be needed.  相似文献

1939年,美国国会制定了《美国联邦税法典》,该税法典以公平正义为理念、以纳税人为中心,构建了一套规模宏大、逻辑严密、技术精巧的税收法律体系,反映了美国在上个世纪以来的法典化进程中的突出成就。吸取《美国联邦税法典》中的核心精神,借鉴该法典中的优良制度,以构建我国的《税法通则》为契机,重构税法制度体系,并为税收立法提供一套科学的长效机制,不仅可以促进税收公平,而且可以提高税收效率。  相似文献

This article reports on an analysis undertaken in the field of African philosophies using selected conceptual tools from Maton’s Legitimation Code Theory (LCT). In response to calls by South African students for ‘decolonising’ the Humanities curriculum, the practical purpose of the analysis was to generate theoretically-informed guidelines for developing a curriculum for an undergraduate course in a new African Studies major. The field of African philosophies is of theoretical interest because historically it has been premised on responding to and challenging dominant, Western ideas imposed on African intellectuals through processes of colonization and modernization. LCT was employed to uncover principles that legitimate knowledge claims in this field – with a view to determining what content should be selected, recontextualized and pedagogized for the new curriculum. The analysis includes the author’s meta-reflections on the affordances and limitations of LCT for working with knowledge in the South.  相似文献
