In light of the World Anti Doping Agency’s 2013 Code Revision process, we critically explore the applicability of two of three criteria used to determine whether a method or substance should be considered for their Prohibited List, namely its (potential) performance enhancing effects and its (potential) risk to the health of the athlete. To do so, we compare two communities of human guinea pigs: (i) individuals who make a living out of serial participation in Phase 1 pharmacology trials; and (ii) elite athletes who engage in what is effectively ‘unregulated clinical research’ by using untested prohibited or non-prohibited performance enhancing substances and methods, alone or in combination. Our comparison sheds light on norms of research ethics that these practices exacerbate with respect to the concepts of multiplicity, visibility, and consistency. We argue for the need to establish a proper governance framework to increase the accountability of these unregulated research practices in order to protect the human guinea pigs in elite sports contexts, and to establish reasonable grounds for the performance enhancing effects, and the risks to the health of the athlete, of the methods and substances that might justify their inclusion on the Prohibited List.  相似文献

A distinguishing characteristic of the biomedical model is its compartmentalized view of man. This way of seeing human beings has its origin in Greek thought; it was stated by Descartes and to this day it still considers humans as beings composed of distinct entities combined into a certain form. Because of this observation, one began to believe that the focus of a health treatment could be exclusively on the affected area of the body, without the need to pay attention to patient’s subjectivity. By seeing pain as a merely sensory response, this model was not capable of encompassing chronic pain, since the latter is a complex process that can occur independently of tissue damage. As of the second half of the twentieth century, when it became impossible to deny the relationship between psyche and soma, the current understanding of chronic pain emerges: that of chronic pain as an individual experience, the result of a sum of physical, psychological, and social factors that, for this reason, cannot be approached separately from the individual who expresses pain. This understanding has allowed a significant improvement in perspective, emphasizing the characteristic of pain as an individual experience. However, the understanding of chronic pain as a sum of factors corresponds to the current way of seeing the process of falling ill, for its conception holds a Cartesian duality and the positivist premise of a single reality. For phenomenology, on the other hand, the individual in his/her unity is more than a simple sum of parts. Phenomenology sees a human being as an intending entity, in which body, mind, and the world are intertwined and constitute each other mutually, thus establishing the human being’s integral functioning. Therefore, a real understanding of the chronic pain process would only be possible from a phenomenological point of view at the experience lived by the individual who expresses and communicates pain.  相似文献

Research focused on the prodromal period prior to the onset of psychosis is essential for the further development of strategies for early detection, early intervention, and disease pre-emption. Such efforts necessarily require the enrollment of individuals who are at risk of psychosis but have not yet developed a psychotic illness into research and treatment protocols. This work is becoming increasingly internationalized, which warrants special consideration of cultural differences in conceptualization of mental illness and international differences in health care practices and rights regarding research participation. The process of identifying and requesting informed consent from individuals at elevated risk for psychosis requires thoughtful communication about illness risk and often involves the participation of family members. Empirical studies of risk reasoning and decisional capacity in young people and individuals with psychosis suggest that most individuals who are at-risk for psychosis can adequately provide informed consent; however ongoing improvements to tools and procedures are important to ensure that this work proceeds with maximal consideration of relevant ethical issues. This review provides a discussion of these issues in the context of international research efforts.  相似文献

The medical profession consistently strives to uphold patient empowerment, equality and safety. It is ironic that now, at a time where advances in technology and knowledge have given us an increased capacity to preserve and prolong life, we find ourselves increasingly asking questions about the value of the lives we are saving. A recent editorial by Professor Raanan Gillon questions the emphasis that English law places on the sanctity of life doctrine. In what was described by Reverend Nick Donnelly as a “manifesto for killing patients”, Professor Gillon argues that the sanctity of life law has gone too far because of its disregard for distributive justice and an incompetent person’s previously declared autonomy. This review begins by outlining the stance of the sanctity of life doctrine on decisions about administering, withholding and withdrawing life-prolonging treatment. Using this as a foundation for a rebuttal, a proposal is made that Professor Gillon’s assertions do not take the following into account:
  1. 1)
    A sanctity of life law does not exist since English Common Law infringes the sanctity doctrine by tolerating quality of life judgements and a doctor’s intention to hasten death when withdrawing life-prolonging treatment.
     
  2. 2)
    Even if a true sanctity of life law did exist:
    1. a)
      The sanctity of life doctrine allows for resource considerations in the wider analysis of benefits and burdens.
       
    2. b)
      The sanctity of life doctrine yields to a competent person’s autonomous decision.
       
     
This review attempts to demonstrate that at present, and with the legal precedent that restricts it, a sanctity of life law cannot go too far.  相似文献

The strength of amodal completion is known to be modulated by contour relationships and global shape. Some researchers have shown that amodal completion also depends on surface similarity, but they have not distinguished the relative importance of similarity in surface representations either pre or post lightness constancy. In the experiments reported here, we aimed to determine whether amodal completion depends on processes that occur either before or after the establishment of lightness constancy. We used computer rendering techniques to vary the consistency of a cast shadow with a decrement in luminance on one side of a partially occluded surface. We found that perceived completion depended on the consistency of the decrement in surface luminance with the orientation of a cast shadow (Exp.?1). In Experiment ?2, we generated occluded surface fragments that could be either luminance-matched or lightness-matched to surface fragments on the opposite side of the occluder, and we found that the strength of amodal completion depended primarily on similarity in the perceived surface reflectance. In Experiments 3 and 4, we performed apparent-motion tasks to obtain converging evidence for grouping on the basis of perceived similarity in lightness. We found that matching surfaces in lightness significantly improved the apparent motion of surfaces behind an occluder, as compared with surfaces that were matched in contrast alone. These results suggest that amodal completion depends on the perceived similarity in lightness of partially occluded surface fragments.  相似文献

Shame has broad importance to psychological problems. However, few interventions specifically address shame, and most of these have been designed to target shame in the context of particular disorders. Self-Acceptance Group Therapy (SAGT) was developed as a transdiagnostic shame-focused treatment, based on a cognitive-behavioral framework. SAGT is an 8-week treatment that involves psychoeducation and training in the use of cognitive and behavioral shame regulation and support-building skills in order to promote self-acceptance. After describing SAGT, the study presented used an open trial design to examine the utility of SAGT for addressing shame, self-acceptance, quality of life, and relevant psychological problems (e.g., depression, social anxiety). Twenty-four outpatients with elevated shame were assessed at pretreatment, posttreatment, and 1-month follow-up. By post-treatment, results revealed significant improvements in self-acceptance, shame, and borderline personality disorder (BPD) symptoms among treatment completers (n = 18), with all of these improvements maintained at follow-up. Additionally, significant improvements in quality of life, emotion dysregulation, depression, loneliness, and stress were observed at follow-up. Results provide preliminary support for SAGT’s utility in the treatment of shame and related pathology among diverse outpatients.  相似文献

I argue that the separation of conjoined twins in infancy or early childhood is unethical (rare exceptions aside). Cases may be divided into three types: both twins suffer from lethal abnormalities, only one twin has a lethal abnormality, or neither twin does. In the first kind of case, there is no reason to separate, since both twins will die regardless of treatment. In the third kind of case, I argue that separation at an early age is unethical because the twins are likely to achieve an irreplaceably good quality of life—the goods of conjoinment—that separation takes away. Evaluation of this possibility requires maturation past early childhood. Regarding the second type, I point out that with conceivable but unrecorded exceptions, these cases will consistently involve sacrifice separation. I present an argument that sacrifice separation is unethical, but in some cases a moral dilemma may exist in which separation and refraining from separation are both unethical. Perhaps in such cases a decision can be made on non-moral grounds; however, the possibility of such a decision serves not to mitigate but to underscore the fact that the separation is unethical. My conclusion, which applies to all three types of cases, is that it is unethical to separate conjoined twins before their developing personalities give some reliable indication as to whether they desire separation and whether they will achieve those goods of conjoinment.  相似文献

In the second book of his Confessions, Augustine of Hippo presents his famous juvenile Pear Theft as an apparent case of acting under the guise of the bad. At least since Thomas Aquinas’ influential interpretation, scholars have usually taken Augustine’s detailed discussion of the case to be dispelling this “guise of the guise of the bad”, and to offer a solid “guise of the good”-explanation. This paper addresses an important challenge to this view: Augustine offers two different “guise of the good”-explanations in his text rather than just one, and the two explanations seem to be mutually exclusive. A number of more recent attempts to reconcile Augustine’s two lines of explanation are discussed and found wanting, and a new suggestion is made. The proposed solution focuses on the Pear Theft as a joint action, and it departs from the Aquinian interpretation in that it accounts for a way in which the “guise of the bad”-hypothesis survives the explanation.  相似文献

A number of theorists have argued that Scanlon's contractualist theory both "gets around" and "solves" the non-identity problem. They argue that it gets around the problem because hypothetical deliberation on general moral principles excludes the considerations that lead to the problem. They argue that it solves the problem because violating a contractualist moral principle in one's treatment of another wrongs that particular other, grounding a person-affecting moral claim. In this paper, I agree with the first claim but note that all it shows is that the act is impersonally wrong. I then dispute the second claim. On Scanlon's contractualist view, one wrongs a particular other if one treats the other in a way that is unjustifiable to that other on reasons she could not reasonably reject. We should think of person-affecting wronging in terms of the reasons had by the actual agent and the actual person affected by the agent's action. In non-identity cases, interpersonal justifiability is therefore shaped both by the reason to reject the treatment provided by the bad suffered and the reason to affirm the treatment provided by the goods had as a result of existing. I argue it would be reasonable for the actual person to find the treatment justifiable, and so I conclude that Scanlon's contractualist metaethics does not provide a narrow person-affecting solution to the non-identity problem on its own terms. I conclude that the two claims represent a tension within Scanlon's contractualist theory itself.  相似文献
