Philip Kitcher presents an ambitious account of pragmatic naturalism that incorporates an explanatory story of the emergence and development of ethics, a metaethical perspective on progress, and a normative stance for moral theorizing. This article contends that Kitcher's normative stance is incompatible with the explanatory and metaethical components of his project. Instead, pragmatic naturalists should endorse a normative ethics that is experimental, grounded in practice, and acutely aware of cognitive and informational limitations. In particular, the ethical project would benefit from endorsing empirical work on participatory democracy for the identification of mechanisms to guide us on deep moral conflicts.  相似文献

Dr. Judith Miranti has contributed over 40 years of service to the Association for Spiritual, Ethical, and Religious Values in Counseling (ASERVIC). The purpose of this article is to highlight and recognize a pioneer and influential leader of ASERVIC. The interview discusses Dr. Miranti's (a) historical knowledge and memories of the development of ASERVIC, (b) involvement in ASERVIC in various leadership roles and with others who influenced her, and (c) hope for the future of ASERVIC.  相似文献

Positive beliefs about worry are theorized to maintain excessive and uncontrollable worry, the hallmark of generalized anxiety disorder (GAD; American Psychiatric Association, 2013). The Why Worry-II (WW-II) is a 25-item revised questionnaire designed to measure five positive beliefs about worry. These five beliefs are that worry: (1) facilitates problem solving; (2) enhances motivation; (3) protects against negative emotions; (4) prevents negative outcomes; and (5) reflects a positive personality trait. The main goal of this study was to assess the WW-II’s psychometric properties, including its factor structure. Undergraduate participants (N = 309) completed the WW-II, and measures of worry, depression, anxiety, and positive and negative beliefs about worry. Overall, the results suggest that the five-factor model is a good fit to the data. The WW-II demonstrated excellent internal consistency, good test–retest reliability at six weeks, and evidence of convergent and divergent validity. The WW-II also uniquely predicted worry severity. Overall, our findings suggest that the WW-II has a five-factor structure congruent with theoretical predictions, sound psychometric properties, and a unique relationship to excessive worry. The theoretical and clinical implications of these findings are discussed.  相似文献

分子靶向药物的出现显示出肿瘤治疗传统模式的重要进展。与传统放疗、化疗相比,分子靶向治疗因其特异性高、不良反应轻微,在恶性肿瘤个体化治疗中扮演重要角色。十五年来,分子靶向药物的出现,给肿瘤的治疗模式带来重大改变,也给临床医生带来新的挑战。准确把握分子靶向药物应用时机,获得最大临床效果,已成为肿瘤治疗领域关注热点。本文就非小细胞肺癌、消化系统肿瘤、乳腺癌、肾癌治疗中分子靶向药物如何选择应用时机进行阐述。  相似文献

个体的情绪伪装能力是其情绪社会化发展极为重要的方面,选取某幼儿园123名3~6岁儿童为被试,通过“区分外表-真实情绪”任务和“错误信念”任务考察3~6岁儿童情绪伪装认知能力的发展特点,进而探讨情绪伪装认知与错误信念理解的关系.结果表明:(1)儿童情绪伪装认知能力随年龄增长而提高,3~5岁为儿童情绪伪装认知能力的快速发展期;(2)儿童在消极情境下区分内外情绪的能力显著高于在积极情境中的表现;同时,对两种情绪伪装动机(社会适应、自我保护)的认知能力无显著差异;(3)儿童情绪伪装认知和错误信念理解能力显著相关,两种错误信念(意外内容、意外地点)理解都能很好地预测情绪伪装认知能力.  相似文献

Weight bias exists across many important life domains, necessitating interventions designed to reduce weight-biased attitudes and beliefs. Though the effectiveness of weight bias interventions has been questioned, to our knowledge no meta-analysis of these interventions has been conducted. This meta-analysis evaluated the impact of weight bias interventions on weight-biased attitudes and beliefs and explored potential moderators. Interventions were eligible if they used an adult sample and a validated measure of weight-biased attitudes, which resulted in the inclusion of 30 studies represented in 29 articles. A random effects approach using inverse weights resulted in a mean effect size estimate of g = −0.33 (lower scores indicate less weight bias) for both attitudes and beliefs. Intervention type, publication type, and population type were not significant moderators but demonstrated noteworthy trends. Results reveal a small, positive effect of weight bias interventions on weight-biased attitudes and beliefs and provide useful information for future interventions.  相似文献

To deal with an uncertain future, global ethics as an academic endeavour might consider a common value we all share, such as sustainability, which acts as an all-encompassing term to indicate our future direction. Technologies of the near future that are currently in development hold problems and promise, and are clear subjects for the ethics of sustainability at a global level. Autonomous military combat robots, insects as food (entomophagy) and in vitro synthetically grown meat are significant cases. Such robots might in fact serve injustice and work against sustainability, and such novel food technologies may hold hope for promoting sustainability and global justice.  相似文献

We examined whether the power of tests as learning events, frequently demonstrated in the laboratory, would also occur in a large undergraduate course. Our goals were to determine: if learning of information tested on multiple-choice quizzes administered across the course would be enhanced compared to non-tested control information; and what the effects of quizzing would be for the learning of information conceptually related to the tested information but not itself tested on the quizzes. Given that retrieval practice can have positive (testing effect) and negative consequences (retrieval-induced forgetting), our concern was that the learning and later retention of non-tested conceptually related information might be impaired by the multiple-choice quizzes. Importantly, learning benefits were found for both types of information on the final exam, indicating that quizzing within a course can enhance not only the learning of specifically tested information, but the learning of non-tested conceptually related information as well.  相似文献
