借鉴循证医学方法促进SARS治疗决策科学化

面对突如其来的严重急性呼吸综合征(SARS),其预防和治疗方案层出不穷.究竟哪一种预防或治疗方法对SARS最有效?怎样面对现有的困难?如何借鉴循证医学的理念及方法,促进SARS治疗决策科学化至关重要.     

临床决策:医学哲学研究的一个重要领域

临床决策研究已成为临床医学中的一个重要领域.当下的临床决策问题涉及到医学信息学、循证医学、费用-效益评估、卫生技术评估、医学伦理与法律等学科领域.因此在临床决策中单一的经验-描述的研究纲领已不适应当代医学发展的需要,需要引入综合的决策方法.临床决策问题也为医学哲学研究提供了一个极佳的思想实验场所.临床决策的多维度研究,对于打通学科之间的壁垒,架构科学与人文之间的桥梁,更深刻地理解和把握医疗保健的整体性,使临床医疗达到最佳疗效具有重要意义.     

The good,the bad and the ugly thing to do when sharing information: Revealing,concealing and lying depend on social motivation,distribution and importance of information

Research on information sharing in group decision-making has widely assumed a cooperative context and focused on the exchange of shared or unshared information in the hidden profile paradigm (36 and 37), neglecting the role of information importance. We argue that information sharing is a mixed-motive conflict setting that gives rise to motivated strategic behavior. We introduce a research paradigm that combines aspects of the traditional information sampling paradigm with aspects of a public good dilemma: the information pooling game. In three experiments, we show that information sharing is strategic behavior that depends on people’s pro-social or pro-self motivation, and that people consider information sharedness and information importance when deciding whether to reveal, withhold, or falsify their private or public information. Pro-social individuals were consistently found to honestly reveal their private and important information, while selfish individuals strategically concealed or even lied about their private and important information.     

Blocking incidental frustration during bargaining

The current study examined the effects of an intervention aimed at blocking the transfer of frustration from a previous experience (i.e. recall task) to a subsequent and unrelated task (i.e. ultimatum bargaining task). Participants who went through the intervention were more likely to accept unfair offers in the ultimatum bargaining task than those who did not go through the intervention. These results show that participants who were blocked from transferring their feelings of frustration from the recall task to the subsequent bargaining task (no-transfer condition) more likely accepted unfair offers than those who inadvertently transferred their feelings of frustration (transfer condition). The effect of conditions on accept-reject decisions in the ultimatum bargaining was mediated by reported feelings of frustration.     

Perceived benefits of using an Internet-based interactive career planning system

Making Better Career Decisions (MBCD) is an Internet-based interactive career planning system designed to help deliberating individuals. The present research examined the benefits of a dialogue with MBCD, by analyzing 712 users’ perceptions of its contribution to their career decision-making process, and locating variables associated with these perceptions. A pre-dialogue and a post-dialogue questionnaire were used to collect the users’ perceptions of its benefits and measure the change in the degree of decidedness. Perceived benefit was derived from participants’ ratings of the degree of progress they had made in their career decision-making process, whether they had learned about additional factors to be considered and their career-related preferences, as well as their ratings of the quality of the list of “promising” career alternatives presented to them during their dialogue with MBCD. This composite perceived benefit was found to be positively associated with the users’ decidedness at the completion of the dialogue with MBCD. Users’ satisfaction with the length and variety of their personal “promising alternatives” list was associated with a higher perceived benefit.     

Remarks on the Absentminded Driver

Piccione and Rubinstein (1997) present and analyse the sequential decision problem of an “absentminded driver”. The driver's absentmindedness (imperfect recall) leads him to time-inconsistent strategy evaluations. His original evaluation gets replaced by a new one under impact of the information that the circumstances have changed, notwithstanding the fact that this change in circumstances has been expected by him all along. The time inconsistency in strategy evaluation suggests that such an agent might have reason to renege on his adopted strategy. As we shall see, however, this danger is only apparent. There is no serious problem of dynamic inconsistency in this case. My diagnosis of the case under consideration is in many respects similar to the one provided by Aumann, Hart and Perry (1997), but the analysis leading to this diagnosis is not quite the same. This revised version was published online in August 2006 with corrections to the Cover Date.     

Gender and Risk in Public Performance

The scarcity of women as contestants on the nationally televised quiz show Who Wants to Be a Millionaire provided the impetus to study gender and risk. In three simulated studies we investigated perception of risk and decision making about whether to engage in a televised public performance. Gender differences consistent with the risk assessment literature were found. Women considered going on the show to be more personally risky, were more concerned about doing poorly in public, and were less likely to risk entering their names. Results were discussed in terms of motivation to avoid negative social consequences. Implications of the findings for women's participation in public life are discussed.     

Guidance on conducting and reviewing systematic reviews (and meta-analyses) in work and organizational psychology

Systematic reviews and meta-analyses are means of summarizing and synthesizing research evidence in a given topic area. They can be used to define the current state of knowledge and how confident we can be in that knowledge, to identify evidence gaps, and to provide recommendations for policy and practice based on the best available evidence. At European Journal of Work and Organizational Psychology, our editorial stance is explicitly to encourage the conduct of systematic reviews and meta-analyses. The purpose of this editorial is to provide some guidance to authors and journal referees on the (technical) features of good systematic reviews.     

动机冲突影响混合跨期决策：趋近-回避动机理论视角

组织与个人面临的许多决策,既无纯粹获益,也无纯粹损失,往往需要同时对未来不同时间点的损益加以权衡,这类损益兼具的决策称为混合跨期决策。过往研究通常沿用纯粹获益或损失跨期决策的理论框架,缺乏与混合跨期决策相匹配的理论建构和决策过程探索。基于此,本研究从趋近-回避动机理论出发,探索动机冲突影响混合跨期决策的过程机制。研究1拟探讨混合跨期决策中动机冲突特点,及其与决策行为之间的关系。研究2则计划分别操纵影响动机冲突程度的内源性因素(得失金额的相对差异程度)和外源性因素(资源有限程度),试图揭示动机冲突程度与混合跨期决策之间的因果链条。研究3拟采用鼠标追踪技术,基于决策过程指标进一步探索动机冲突影响混合跨期决策的过程机制。我们预期该研究结果有利于从动机冲突视角揭示并建构混合跨期决策的作用机制,同时也将为涉及混合跨期情境的企业管理和个体消费决策提供科学依据。     

Match-fixing: Moral challenges for those involved

ABSTRACT

Match-fixing is a major ethical issue in sports. Although research interest in match-fixing has increased in recent years, we remain largely in the dark regarding how both betting- and non-betting-related match-fixing relate to the moral decision-making of those involved. Drawing on Rest’s theory of morality and on the perceptions of a large sample (n = 567) of participants in Flemish sports, this study indicates that most match-fixing incidents are non-betting-related, while moral motivation and associated challenges clearly differ according to the type of match-fixing. Therefore, each type of match-fixing requires different preventive measures.
