Trust is an essential element in productive and effective intraorganizational communication and interaction. The present study examined several consequences of trust in terms of influence strategies used and the frequency with which people interact with each other. The study also examined the extent to which the technology of work affects management's dependency on their employees. It was found that distrust of subordinates by managers (n = 275) was associated with the use of strong tactics of influence, little dependency on employees, and the use of personal-related characteristics to explain distrust. It was also found that distrust of managers by subordinates (n = 267) was associated with the use of strong methods of influence, less interaction, less attempts to influence, and the use of personal-related characteristics to explain lack of trust. These findings have clear implications for understanding the relation among worker trust, dependency, and social influence. The data suggest that both employees and employers could benefit from considering the importance of a trusting relationship in the workplace. 相似文献

20世纪全球卫生发展的回顾与展望 总被引:3,自引:0,他引:3
20世纪人类的健康状况发生了革命性的转变,同时也面临着前所未有的挑战。疾病谱的改变及人口寿命的延长以及医疗费用的上涨仍然是困扰各国决策者的难题,卫生发展与改革任重道远。完善健康保障体系最理想的选择方案是政府为居民“购买”基本卫生服务,由国家财政和居民共同承担保险基金,普及初级卫生保健,鼓励多种形式办医,WHO确定的卫生工作目标是各成员国卫生系统改革与发展的指导方针。 相似文献

本研究采用师生关系教师评定量表,由14名班主任教师对498名3-6年级学生与教师的关系进行评价.结果表明:(1)师生关系量表具有较好的信度和效度,师生关系特点主要表现在冲突性、亲密性和反应性三个维度上.(2)快速聚类分析的结果表明,3-6年级学生的师生关系可划分为3种类型:冷漠型、冲突型、亲密型,其分布比例分别为23.0%、33.7%、43.3%.(3)师生关系随学生年级增长而变化.在师生关系各维度及总分上,存在显著的年级差异.随年级的上升,积极师生关系类型的比例逐渐下降,而消极师生关系类型的比例逐步上升. 相似文献

This study examined the impact of thought suppression on the quality of cognitive processing and self-reported mood. While completing a stream-of-consciousness task about two topics sequentially, participants were either instructed to suppress negative thoughts or were given no suppression instructions. Computer-based content analyses indicated that thought suppression led to significantly less causal reasoning and discrepancy seeking. However, the suppression of negative thoughts also resulted in a more positive mood. Results suggest that thought suppression can improve mood but it comes with the cognitive cost of superficial processing. 相似文献

This article examines the interrelationship between old age, professional power, and social policy. In particular, dominant theoretical models in social gerontology are reviewed and an alternative framework for understanding social gerontological issues—Foucauldian gerontology—is advanced. Foucauldian narratives are employed to delineate the historical relationship between professional social work and recent social policy for older people in the United Kingdom. In addition, a Foucauldian framework employed to examine identity formation, professional practices, and policy narratives enriches and widens the disciplinary subject matter of theorizing aging studies. The structure of this article is in three parts: review of theories of aging with an introduction of Foucault's potential contribution to gerontological analysis, the historical overview of the instigation of professional intervention in modernity and the changing roles and responsibilities in relation to older people utilizing Foucault's (1977) genealogical method, and the exploration and application of Foucault's key notion of governmentality (1977; Rose & Miller, 1992) in the analysis of social policy for older people. 相似文献

We examined a combined approach of manipulating reinforcer dimensions and delay fading to promote the development of self‐control with 3 students diagnosed with attention deficit hyperactivity disorder. First, we administered a brief computer‐based assessment to determine the relative influence of reinforcer rate (R), reinforcer quality (Q), reinforcer immediacy (I), and effort (E) on the students' choices between concurrently presented math problems. During each session, one of these dimensions was placed in direct competition with another dimension (e.g., RvI involving math problem alternatives associated with high‐rate delayed reinforcement vs. low‐rate immediate reinforcement), with all possible pairs of dimensions presented across the six assessment conditions (RvQ, RvI, RvE, QvI, QvE, IvE). The assessment revealed that the choices of all 3 students were most influenced by immediacy of reinforcement, reflecting impulsivity. We then implemented a self‐control training procedure in which reinforcer immediacy competed with another influential dimension (RvI or QvI), and the delay associated with the higher rate or quality reinforcer alternative was progressively increased. The students allocated the majority of their time to the math problem alternatives yielding more frequent (high‐rate) or preferred (high‐quality) reinforcement despite delays of up to 24 hr. Subsequent readministration of portions of the assessment showed that self‐control transferred across untrained dimensions of reinforcement. 相似文献

准备时间和预先信息对任务切换的影响 总被引:2,自引:1,他引:1
两个实验采用任务线索范式,考察了准备时间和预先信息对任务切换的影响。实验1的准备时间为可预测,实验2的为不可预测,以考察准备时间的可预测性对任务切换的影响。以被试执行重复任务、切到任务和切离任务的正确反应时为主要指标,结果:(1)在准备时间可预测和不可预测两种条件下,准备时间和预先信息之间存在显著交互作用。在可预测条件中,重复和切到任务的反应时随着准备时间的增加而减少,但切到代价无显著变化,切离任务的反应时不受准备时间的影响,切离代价表现出反准备效应;不可预测条件下,三种任务的反应时都随着准备时间的增加而减少,但是切到和切离代价表现出反准备效应;(2)切离任务的反应时和代价显著高于切到任务的反应时和代价;(3)在这两种条件下,都没有出现切换代价的准备效应 相似文献

采用《儿童学习适应性调查表(I)、(II)》和《学习习惯与应试技能自我测查表》对231名学优儿童的学习适应性及其相关因素进行调查。结果表明:(1)学优儿童和学习不良儿童的学习适应性、学习习惯和应试技能存在显著性差异;(2)城市学优儿童的学习生活、学习习惯、学习方法、阅读习惯和技能明显优于农村学优儿童;(3)学优女生在学习适应性明显好于男生,但女生有独立性差、情绪障碍等症状,而学优男生则在学习习惯方面不如女生。在学习习惯与应试技能方面则不存在显著的性别差异;(4)除了对学校的态度因子外,学优儿童学习适应性与其学习习惯和学习方法、阅读习惯和技能、准备与应试等有显著性相关。 相似文献

The article argues that the most important trends in the recent metamorphosis of higher education, especially of university teaching and research, cannot be understood without placing them in the context of general developments in political life. Both processes reveal alarming features and there is a link between them. In recent decades a religion has established its dominance in the public policy field. Its dogmas are called “liberalization”, “economic man”, “individual preference”, “the free market”, “competition” and “efficiency”. The consequences of the progressive imposition of this doctrine on the universities—including on the relation between teaching and research—are well documented but not always well understood. It is argued that the “commercialization” of higher education and research means in reality their hyper-bureaucratization, via the imposition of so-called evaluation, assessment and accreditation schemes, the latest avatars of the managerialist ideology. Might the final result be the disintegration of the university as an institution? 相似文献
