The idea that payment for research participation can be coercive appears widespread among research ethics committee members, researchers, and regulatory bodies. Yet analysis of the concept of coercion by philosophers and bioethicists has mostly concluded that payment does not coerce, because coercion necessarily involves threats, not offers. In this article we aim to resolve this disagreement by distinguishing between two distinct but overlapping concepts of coercion. Consent-undermining coercion marks out certain actions as impermissible and certain agreements as unenforceable. By contrast, coercion as subjection indicates a way in which someone’s interests can be partially set back in virtue of being subject to another’s foreign will. While offers of payment do not normally constitute consent-undermining coercion, they do sometimes constitute coercion as subjection. We offer an analysis of coercion as subjection and propose three possible practical responses to worries about the coerciveness of payment. 相似文献

Withholding and withdrawing treatment are widely regarded as ethically equivalent in medical guidelines and ethics literature. Health care personnel, however, widely perceive moral differences between withholding and withdrawing. The proponents of equivalence argue that any perceived difference can be explained in terms of cognitive biases and flawed reasoning. Thus, policymakers should clear away any resistance to accept the equivalence stance by moral education. To embark on such a campaign of changing attitudes, we need to be convinced that the ethical analysis is correct. Is it? In this article, I take a closer look at the moral relation between withholding and withdrawing. My conclusion is that withholding and withdrawing are not in general ethically equivalent. Thus, medical guidelines should be rewritten, and rather than being “educated” away from their sound judgments, medical professionals and patients should have nuanced medico-ethical discussions regarding withholding and withdrawing treatment. 相似文献

Classic statements of research ethics advise against permitting physician-investigators to obtain consent for research participation from patients with whom they have preexisting treatment relationships. Reluctance about “dual-role” consent reflects the view that distinct normative commitments govern physician–patient and investigator–participant relationships, and that blurring the research–care boundary could lead to ethical transgressions. However, several features of contemporary research demand reconsideration of the ethics of dual-role consent. Here, we examine three arguments advanced against dual-role consent: that it creates role conflict for the physician-investigator; that it can compromise the voluntariness of the patient-participant’s consent; and that it promotes therapeutic misconceptions. Although these concerns have merit in some circumstances, they are not dispositive in all cases. Rather, their force—and the ethical acceptability of dual-role consent—varies with features of the particular study. As research participation more closely approximates usual care, it becomes increasingly acceptable, or even preferable, for physicians to seek consent for research from their own patients. It is time for a more nuanced approach to dual-role consent. 相似文献

工作旺盛感是个体在工作中同时感受活力和学习一种心理状态。组织情境中领导、组织支持和公平、工作特征和同伴均影响工作旺盛感。基于特质激活和自我决定理论, 构建“组织情境影响工作旺盛感的心理机制”模型:“全景式”和“离散式”组织情境能直接影响基本心理需求的满足, 或者先激活特质, 再影响基本心理需求满足, 进而影响工作旺盛感。未来应加强“全景式”组织情境及其中介机制研究, 开展个体和组织情境变量以及社会层和任务层等多层次整合研究, 并运用动态研究方法研究组织情境与工作旺盛感之间的联动变化规律, 预测工作旺盛感。 相似文献

根据社会交换理论和人与情境互动理论,研究探讨了个人-组织匹配对员工组织公民行为的影响机制。通过对12家餐饮连锁店225位员工进行的问卷调查,结果表明:个人-组织匹配正向预测组织公民行为,员工工作敬业度在两者关系中起中介作用;此外,分别作为情境因素和个体因素的主管支持、员工主动性人格对个人-组织匹配与组织公民行为之间的关系具有调节作用。主管支持的程度越高,个人-组织匹配与组织公民行为的正向关系更强;而对于高主动性人格的员工,个人-组织匹配与组织公民行为之间的正向关系反而更弱。 相似文献

本研究通过两时点纵向问卷调查,探讨主动性人格与组织公民行为、任务绩效之间的关系,考察主动社会化行为在其中的中介作用,以及政治技能的调节作用。结果表明:(1)主动社会化行为在主动性人格和组织公民行为、任务绩效之间起中介作用;(2)政治技能对主动社会化行为在主动性人格和组织公民行为、任务绩效之间的中介效应起调节作用:当政治技能水平上升,主动性人格通过主动社会化行为对组织公民行为及任务绩效的预测更加明显。 相似文献

Building on conservation of resources theory and social exchange theory, the author examined the relationship between supervisor support and organizational commitment through work–family conflict, work–life balance, and the job satisfaction of employees working in the financial sector in Australia. The study comprised 305 employees recruited through an online survey. Results indicate that supervisor support is negatively related to work–family conflict. In turn, work–life balance and job satisfaction are negatively linked to work–family conflict. The results further show that both work–life balance and job satisfaction are positively related to organizational commitment. Theoretical and practical implications, as well as limitations, are discussed. 相似文献
