We examined the satisfaction in and perceived quality of information about one’s job, business unit, and company, as well as perceived quality of urgent news (i.e., news about changes in business and generally considered legally sensitive material), communicated via different media. Results from 598 fulltime employees revealed that rich media (e.g., face-to-face) was most related to satisfaction in information about one’s job and business unit and in perceived quality of information from the supervisor; lean media (e.g., company newsletter) was most related to satisfaction in and quality of information from top management, while moderate media (e.g., e-mail) was only significantly related to perceived quality of urgent news. Trust in top management was positively related to satisfaction in and quality of information shared by management. Lean media most strongly related to quality of urgent news, over and above rich communication.The authors would like to thank Monica Moloney for her support on this project.  相似文献

Strategic Maneuvering: A Synthetic Recapitulation   总被引:1,自引:0,他引:1  
As an introduction to the special issue on Perspectives on Strategic Maneuvering, this article provides a synthetic recapitulation of the various steps that were taken in developing the pragma-dialectical theory of strategic maneuvering. First, the concept of strategic maneuvering is described as a means to reconcile the simultaneous pursuit of dialectical and rhetorical aims. Second, strategic maneuvering is related to the various kinds of argumentative activity types in which it takes place. Third, the concept of dialectical profiles is discussed and the parameters that are pertinent to distinguishing between different types of strategic maneuvering. Fourth, the fallacies are viewed as derailment of strategic maneuvering. Fifth, as a case in point, strategic maneuvering with inconsistency is examined. This contribution brings together insights that earlier were put forward in a number of separate publications.  相似文献

This is an examination of two essays on minimal religion by Mikhail Epstein (1982 and 1999), assessing the usefulness of the term ‘minimal religion’ for the analysis of religion in contemporary Russia. An adapted version of a paper delivered at the School of Slavonic and East European Studies (SSEES), University of London, on 8 December, 2003. Note regarding Mikhail Epstein’s use of the words ‘religion’, ‘religiosity’ and ‘spirituality’: Epstein uses the word ‘religion’ to signify ‘mainstream’, church-based manifestations of religion and also the institutional, hierarchical structures related to those. Although in English usage the word ‘religiosity’ has negative connotations – signifying either a superficially felt religious sentiment or a somehow false and insincere expression of religious feeling, intended for outward show – Epstein appears to use the term entirely neutrally. For him it simply serves as a synonym for the word ‘spirituality’. In the two essays examined in the present article the word ‘spirituality’ signifies the whole inner spiritual life and aspirations of the individual and her/his reflection on an ethical way of living, whether the person concerned is a committed, church-going believer, or someone engaged in a personal spiritual or philosophical quest for meaning, or else someone who has experienced what Epstein refers to as ‘the wilderness’ of the Soviet years and has learnt of a spiritual dimension to life through that formative experience.  相似文献

This paper presents Automath encodings (which are also valid in LF/λP) of various kinds of foundations of mathematics. Then it compares these encodings according to their size, to find out which foundation is the simplest.

The systems analyzed in this way are two kinds of set theory (ZFC and NF), two systems based on Church's higher order logic (Isabelle/Pure and HOL), three kinds of type theory (the calculus of constructions, Luo's extended calculus of constructions, and Martin-Löf's predicative type theory) and one foundation based on category theory.

The conclusions of this paper are that the simplest system is type theory (the calculus of constructions), but that type theories that know about serious mathematics are not simple at all. In that case the set theories are the simplest. If one looks at the number of concepts needed to explain such a system, then higher order logic is the simplest, with twenty-five concepts. On the other side of the scale, category theory is relatively complex, as is Martin-Löf's type theory.

图形项目记忆与位置来源提取的ERP研究   总被引:1,自引:0,他引:1  
采用事件相关电位(ERP)方法研究大学生图形项目记忆与位置来源提取新/旧效应的时、空分布特征。学习屏幕左侧(或右侧)呈现的图形后在屏幕中央呈现某一测验项目(已学图形或新图形),对受试者进行两类测验:其一是判断该项目是否已学过;其二是将从某侧学过的测验项目判断为目标,而将其它测验项目判断为非目标的来源测验(排除任务)。实验结果表明:图形位置来源提取比项目再认新/旧效应的头皮分布更广,持续时程更长;与前人相同实验范式的研究结果相比,本研究位置来源提取效应的头皮分布范围较广;非目标-旧图形与目标图形新/旧效应的头皮激活程度不同。上述结果说明:图形位置来源提取比项目再认激活的大脑区域更多,这与双重加工模型的观点一致;实验范式和来源知觉的特性共同调节来源记忆新/旧效应的时、空分布特征;意识水平对来源信息提取的新/旧效应存在一定的影响  相似文献

The current project tested a diagnostic approach to selecting interventions to increase patron selection of reusable dinnerware in a cafeteria. An assessment survey, completed by a sample of 43 patrons, suggested that the primary causes of wasteful behavior were (a) environmental arrangement of dinnerware options and (b) competing motivational variables. A functional relation between environmental arrangement and reusable product selection was demonstrated in a reversal design. However, the largest effect occurred as function of a multicomponent intervention involving environmental arrangement, employee involvement, and personal spoken prompts with motivational signs. The results support the use of informant assessments when designing community interventions.  相似文献

药物产品责任的伦理研究   总被引:1,自引:0,他引:1  
对药物产品责任的监管与立法必须与药物的特殊性相吻合。在药物的产品责任伦理上,社会公益至上是首要的;药物的产品责任伦理应该以安全性为基础,又必须对这种安全性的相对性予以确认,来确立对药物风险和危害的监管与控制,探讨了建设我国药物产品责任伦理与法制的举措。  相似文献

采用MBTI对中国和澳大利亚管理者人格类型的性别差异进行了比较研究.结果表明,在人格的维度、维度组合、类型上,澳大利亚管理者比中国管理者有更大的性别差异;而两国男性管理者在人格的维度、维度组合、类型上的差异比两国女性管理者的差异更大.研究同时发现,中国男、女管理者人格类型的分布都较集中,澳大利亚男、女管理者的人格类型分布都较均衡.  相似文献
