The human species enjoys uniquely developed capacities for analytical reasoning and rational decision making, but these capacities come with a price: They make us aware of our inevitable physical death. Drawing on terror management theory and dual-process theories of cognition, we investigate the impact of mortality awareness on analytical reasoning. Two experiments show that experimentally induced thoughts of death impair analytical reasoning performance, just as cognitive load would. When made aware of their own mortality, reasoners allocate their executive resources to the suppression of this disturbing thought, therefore impairing their performance on syllogisms that require analytic thought. This finding has consequences for all aspects of rational thinking that draw on executive resources, and calls for an integrated approach to existential psychology and the psychology of rational thought.  相似文献

Using a self-report questionnaire from the aggressor's point of view, this study contrasted employees' frustration, perception of procedural justice, organizational commitment, and their relationships to interpersonal deviance in Canada and Belgium. Significant main effects were found in both countries for frustration and procedural justice on psychological and physical violence. Moreover, hierarchical regression analyses revealed significant interactions of country by normative and continuance commitment in interpersonal deviance, indicating the unique patterns relationships in Canada and Belgium. Hofstede's model of cultural dimensions was used to discuss the results.  相似文献

This study aimed to better understand the psychological mechanisms, referred to in the job demands–resources model as the energetic and motivational processes, that can explain relationships between job demands (role overload and ambiguity), job resources (job control and social support), and burnout (emotional exhaustion, depersonalization, and personal accomplishment). Drawing on self-determination theory, we examined whether psychological resources (perceived autonomy, competence, and relatedness) act as specific mediators between particular job demands and burnout as well as between job resources and burnout. Participants were 356 school board employees. Results of the structural equation analyses provide support for our hypothesized model, which proposes that certain job demands and resources are involved in both the energetic and motivational processes—given their relationships with psychological resources—and that they distinctively predict burnout components. Implications for burnout research and management practices are discussed.  相似文献

ABSTRACT

Introduction: The aim of this study was to evaluate whether the classic asymmetry seen in hemispheric functioning is modified in older adults by using a verbal-manual concurrency task. Method: Thirty-five right-handed participants divided into two groups according to age (15 older participants, mean age: 68 ± 8 years, without cognitive decline and 20 younger participants, mean age: 23 ± 2 years) had to perform a 30-second uni-manual tapping task, in both a single task (tapping alone) and dual task (tapping and performing a letter fluency task together) condition. Results: In younger participants, the letter fluency task disrupted the right hand more than the left hand whereas, in older participants, the letter fluency task disrupted both hands equally. Conclusion: These results should be considered preliminary data using a behavioral dual task condition, which might be useful for studying lateralized hemispheric functioning and the processes of divided attention during aging.  相似文献

Senior physicians of modern medicine in India play a key role in shaping policies and public opinion and institutional management. This paper explores their perceptions of medical tourism (MT) within India which is a complex process involving international demands and policy shifts from service to commercialisation of health care for trade, gross domestic profit, and foreign exchange. Through interviews of 91 physicians in tertiary care hospitals in three cities of India, this paper explores four areas of concern: their understanding of MT, their views of the hospitals they work in, perceptions of the value and place of MT in their hospital and their views on the implications of MT for medical care in the country. An overwhelming majority (90%) of physicians in the private tertiary sector and 74.3 percent in the public tertiary sector see huge scope for MT in the private tertiary sector in India. The private tertiary sector physicians were concerned about their patients alone and felt that health of the poor was the responsibility of the state. The public tertiary sector physicians’ however, were sensitive to the problems of the common man and felt responsible. Even though the glamour of hi-tech associated with MT dazzled them, only 35.8 percent wanted MT in their hospitals and a total of 56 percent of them said MT cannot be a public sector priority. 10 percent in the private sector expressed reservations towards MT while the rest demanded state subsidies for MT. The disconnect between their concern for the common man and professionals views on MT was due to the lack of appreciation of the continuum between commercialisation, the denial of resources to public hospitals and shift of subsidies to the private sector. The paper highlights the differences and similarities in the perceptions and context of the two sets of physicians, presents evidence, that questions the support for MT and finally analyzes some key implications of MT on Indian health services, ethical issues emerging out of that and the need for understanding the linkages between public and private sectors for a more effective intervention for an equitable medical care policy.  相似文献

Background

Medical tourists, persons that travel across international borders with the intention to access non-emergency medical care, may not be adequately informed of safety and ethical concerns related to the practice of medical tourism. Researchers indicate that the sources of information frequently used by medical tourists during their decision-making process may be biased and/or lack comprehensive information regarding individual safety and treatment outcomes, as well as potential impacts of the medical tourism industry on third parties. This paper explores the feedback from former Canadian medical tourists regarding the use of an information sheet to address this knowledge gap and raise awareness of the safety and ethical concerns related to medical tourism.

Results

According to feedback provided in interviews with former Canadian medical tourists, the majority of participants responded positively to the information sheet and indicated that this document prompted them to engage in further consideration of these issues. Participants indicated some frustration after reading the information sheet regarding a lack of know-how in terms of learning more about the concerns discussed in the document and changing their decision-making. This frustration was due to participants’ desperation for medical care, a topic which participants frequently discussed regarding ethical concerns related to health care provision.

Conclusions

The overall perceptions of former medical tourists indicate that an information sheet may promote further consideration of ethical concerns of medical tourism. However, given that these interviews were performed with former medical tourists, it remains unknown whether such a document might impact upon the decision-making of prospective medical tourists. Furthermore, participants indicated a need for an additional tool such as a website for continued discussion about these concerns. As such, along with dissemination of the information sheet, future research implications should include the development of a website for ongoing discussion that could contribute to a raised awareness of these concerns and potentially increase social responsibility in the medical tourism industry.

Jean Hamburger (1909–1992) is considered the founder of the concept of medical intensive care (réanimation médicale) and the first to propose the name Nephrology for the branch of medicine dealing with kidney diseases. One of the first kidney grafts in the world (with short-term success), in 1953, and the first dialysis session in France, in 1955, were performed under his guidance. His achievements as a writer were at least comparable: Hamburger was awarded several important literary prizes, including prix Femina, prix Balzac and the Cino del Duca prize (1979), awarded, among others, to Jorge Luis Borges and Konrad Lorenz.Here we would like to offer a selected reading of a “golden” book, “Conseils aux étudiants en medicine de mon service” (“Advice to the Medical Students in my Service”), the first book dedicated to patient-physician relationship in Nephrology, written when dialysis and transplantation were becoming clinical options (1963). The themes include: the central role of the patient, who should be known by name, profession, life style, and not by disease; the importance of the setting of the care; the need for truth-telling and for leaving hope; the role of research not only in the progression of science, but also in the daily clinical practice.  相似文献

Introduction

Physicians vary in their moral judgments about health care costs. Social intuitionism posits that moral judgments arise from gut instincts, called “moral foundations.” The objective of this study was to determine if “harm” and “fairness” intuitions can explain physicians’ judgments about cost-containment in U.S. health care and using cost-effectiveness data in practice, as well as the relative importance of those intuitions compared to “purity”, “authority” and “ingroup” in cost-related judgments.

Methods

We mailed an 8-page survey to a random sample of 2000 practicing U.S. physicians. The survey included the MFQ30 and items assessing agreement/disagreement with cost-containment and degree of objection to using cost-effectiveness data to guide care. We used t-tests for pairwise subscale mean comparisons and logistic regression to assess associations with agreement with cost-containment and objection to using cost-effectiveness analysis to guide care.

Results

1032 of 1895 physicians (54%) responded. Most (67%) supported cost-containment, while 54% expressed a strong or moderate objection to the use of cost-effectiveness data in clinical decisions. Physicians who strongly objected to the use of cost-effectiveness data had similar scores in all five of the foundations (all p-values?>?0.05). Agreement with cost-containment was associated with higher mean “harm” (3.6) and “fairness” (3.5) intuitions compared to “in-group” (2.8), “authority” (3.0), and “purity” (2.4) (p?<?0.05). In multivariate models adjusted for age, sex, region, and specialty, both “harm” and “fairness” were significantly associated with judgments about cost-containment (OR?=?1.2 [1.0-1.5]; OR?=?1.7 [1.4-2.1], respectively) but were not associated with degree of objection to cost-effectiveness (OR?=?1.2 [1.0-1.4]; OR?=?0.9 [0.7-1.0]).

Conclusions

Moral intuitions shed light on variation in physician judgments about cost issues in health care.

The meaningful consideration of cultural practices, values and beliefs is a necessary component in the effective translation of advancements in neuroscience to clinical practice and public discourse. Society’s immense investment in biomedical science and technology, in conjunction with an increasingly diverse socio-cultural landscape, necessitates the study of how potential discoveries in neurodegenerative diseases such as Alzheimer disease are perceived and utilized across cultures. Building on the work of neuroscientists, ethicists and philosophers, we argue that the growing field of neuroethics provides a pragmatic and constructive pathway to guide advancements in neuroscience in a manner that is culturally nuanced and relevant. Here we review a case study of one issue in culturally oriented neuroscience research where it is evident that traditional research ethics must be broadened and the values and needs of diverse populations considered for meaningful and relevant research practices. A global approach to neuroethics has the potential to furnish critical engagement with cultural considerations of advancements in neuroscience.  相似文献
