Integrating social comparison and social influence perspective within a social exchange theoretical framework, we examine how the exchange ideologies of employees and their coworkers affect the quality of the employees’ social exchanges. Drawing from social exchange theory, we hypothesize that the exchange ideology of a focal employee has a negative relationship with the quality of his/her social exchange with the organization (i.e., felt obligation) and the quality of his/her social exchange with a leader (i.e., leader–member exchange), both of which are related to task performance. Furthermore, we propose that a coworker close to the employee acts as a social referent and provides cues to exert influence on these relationships. Using data collected from 374 (employee–coworker–manager) triads in Hong Kong, we find support for the aforementioned relationships as well as the moderating roles of a coworker’s exchange ideology. 相似文献

We investigated how Justice Sensitivity (JS) shapes the processing of justice‐related information. We proposed that due to frequently perceiving and ruminating about injustices, persons high in JS develop highly accessible and differentiated injustice concepts that shape attention, interpretation and memory for justice‐related information. Three studies provided evidence for these assumptions. After witnessing injustice, persons high in JS attended more strongly to unjust stimuli than to negative control stimuli (Study1) and interpreted an ambiguous situation as less just than persons low in JS (Study2). Finally, they displayed a memory advantage for unjust information (Study3). Results suggest that JS involves the availability and accessibility of injustice concepts as parameters of cognitive functioning and offer explanations for effects of JS on justice‐related behaviour.

In three experiments the problem is investigated how people identify early in the decision process those alternatives that are worthwhile to be examined in more detail. We assume that decision makers employ the Advantages first Principle: They first search for information about positive outcomes and then focus their information search (e.g., for negative consequences or for risk defusing operators) on those alternatives that appear attractive after this initial evaluation. In Experiment 1 (120 participants), initial information about consequences was varied for eight alternatives (no information, positive consequences, negative, or mixed for four alternatives). In all conditions, the great majority of participants followed both aspects of the Advantages first Principle. In Experiment 2, 60 participants decided in two quasi‐realistic scenarios with two alternatives each. Initial information was presented so that one alternative had better positive consequences, worse negative consequences, or both. In all conditions, more information was searched for in the initially better alternative. In Experiment 3 (20 participants) the Advantages first Principle was not only confirmed for a scenario but also for choices in traditional gambling tasks with two and eight alternatives, respectively. Participants could win or lose real money. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

A blockchain can be considered a technological phenomenon that is made up of different interconnected and autonomous systems. Such systems are referred to here as cyber‐physical systems: complex interconnections of cyber and physical components. When cyber‐physical systems are interconnected, a new whole consisting of a system of systems is created by the autonomous systems and their intercommunication and interaction. In a blockchain, individual systems can independently make decisions on joint information transactions. The decision‐making procedures needed for this are executed based on fault‐tolerant communication and voting and consensus procedures, while the results of these decision‐making procedures are stored in distributed ledgers. Due to the intercommunication, interaction, and independent decision making by autonomous systems, the new whole of a blockchain is a complex entity. Complexity science rather than the usual reductionist scientific approach can help us better understand the behaviour of the new and continuously developing whole of a blockchain as a technological phenomenon. 相似文献

研究以混合物分类为实验任务,探讨在面对口语和文字两种信息时,4~6岁中国幼儿的信任特点,在信任任务之后的即时和延时两个时间点上考察幼儿对所信任信息的运用,以及分析阅读水平对幼儿信息信任和运用的影响。研究结果表明:(1)4~6岁中国幼儿对不同类型信息都表现出高度信任,相较于口语信息,阅读水平高的幼儿表现出对文字信息的信任偏好;(2)幼儿在后续任务中较少运用所信任的信息,随着时间的推移,幼儿运用的口语信息持续减少,但文字信息的运用呈现先降后升的特点;(3)阅读水平在不同时间点上影响幼儿对所信任信息的运用,阅读水平低的幼儿在短时间内更多地运用口语信息,而阅读水平高的幼儿在更长时间里显著更多地使用文字信息。未来研究应进一步探究文字意识对幼儿文字信息信任和后续运用的作用。 相似文献

领导情绪对员工绩效有非常重要的影响, 但并非总是遵循“对称假设”。在特定条件下, 领导表达的消极情绪对员工绩效起到积极作用。情绪即社会信息模型(EASI)可以通过情绪表达者、情绪接受者、组织氛围和组织文化四个角度解释这一不对称现象, 但也存在局限性。文章在以往研究的基础上, 从情绪和认知两条路径出发, 对领导情绪和员工绩效间的中介机制及影响因素进行了系统梳理, 并提出了一个整合模型。未来研究应该关注:领导消极情绪表达的时机和程度, 不同类型的消极情绪对员工绩效的影响, 员工情绪反应的差异性。 相似文献

The Survivor Interaction Contrast (SIC) is a powerful tool for assessing the architecture and stopping rule of a model of mental processes (Townsend & Nozawa, 1995). Despite its demonstrated utility, the methodology has lacked a method for statistical testing until now. In this paper we briefly describe the SIC then develop some basic statistical properties of the measure. These developments lead to a statistical test for rejecting certain classes of models based on the SIC. We verify these tests using simulated data, then demonstrate their use on data from a simple cognitive task. 相似文献

病历书写中的质量缺陷存在于主诉、病史、体格检查、病程记录、诊断等各个方面。提高医学生病历书写质量及临床思维能力,是完成高质量病历书写的关键。同时病历书写有关的法律、法规相继出台,对病历书写提出了新的挑战。 相似文献

ICU实行的基本是封闭式管理,这不仅带来了一些伦理问题,也容易引发医疗纠纷,从伦理学的需要、预防医疗纠纷、改善医患关系等方面探讨ICU向患者家属开放的必要性,分析开放存在的问题,论证了ICU向患者家属开放的可行性。 相似文献
