Abstract This paper discusses three questions concerning the ethics of performance enhancement in sport. The first has to do with the improvement to policy and argues that there is a need for policy about doping to be re-constituted and to question the conceptual priority of ‘anti’ doping. It is argued that policy discussions about science in sport must recognise the broader context of sport technology and seek to develop a policy about ‘performance’, rather than ‘doping’. The second argues that a quantitative enhancement to a sporting performance has no value and is, thus, unethical, unless the motivation behind using it implies something meaningful about being human. Thus, unless the use of the technology is constitutive of our humanness, then it is not a justifiable method of altering (rather than enhancing) performance. This rules out the legitimacy of using performance enhancement to gain an advantage over other competitors, who do not have access to similar means. Finally, the third argument claims that sport ethics has had only a limited discourse and has failed to recognise broader theoretical ideas in relation to performance modification, which might be found in the philosophy of technology and bioethics. Collectively, these positions articulate important concerns about the role of science in sport and the ethical discussions arising from them. 相似文献

狭义的遗传工程专指基因工程,它包括外源基因的分离,转移,整合与表达等一系列步骤。其中外源基因的转移需要借助载体。本文综述了载体的基本条件,几种常用载体及构建,并进一步探讨了遗传工程中选择或构建载体应当考虑的一些问题。 相似文献

We present an active way to use a computer animation in secondary molecular genetics class. For this purpose we developed
an activity booklet that helps students to work interactively with a computer animation which deals with abstract concepts
and processes in molecular biology. The achievements of the experimental group were compared with those of a control group
by means of a written questionnaire, which the students received right after the molecular genetics instruction. Analysis
of the post-test showed that the mean score of the experimental group was significantly higher than the mean score of the
control group. This positive trend was also reflected in personal interviews. 相似文献

Understanding the etiology and relationship between standardized intelligence and academic achievement tests is essential, given their ever-increasing role in American education. Behavioral genetic studies have examined the genetic and environmental etiology of intelligence, academic achievement, and their relationship. Results suggest that genetic, shared environmental, and nonshared environmental influences have an impact on intelligence and academic achievement. Behavioral genetic studies also suggest that the importance of genes may vary as a function of age. Other studies suggest that genes drive the correlation and that the nonshared environment drives the discrepancy between measures of intelligence and achievement. Implications for the identification of intellectually and academically relevant environmental influences are discussed. 相似文献
