This article draws on fieldwork conducted in the back‐office of a major retail UK bank and explores how, when introducing change, management drew on contradictory normative and rational discourses. Its primary concern is to explore how, in this context, employees engaged in contradictory acts that combined elements of both resistance (‘making out’) and consent (‘making do’) that are difficult to disentangle. It is argued that although both are moves within the game, they can be distinguished from each other because the former works against the grain of corporate intentions, whereas the latter works with them.  相似文献

The power motive, defined as the desire to impact the behavior and emotions of another person, has long been controversial. On one side, the exercise of power has been put forth as a fundamental human need greater in strength than the need to survive. On the other, it has been vilified for its potentially devastating consequences. We argue the latter view is distorted, and, by relying too heavily on it, we have come to misunderstand the essential nature of power and its use by leaders charged with driving performance. It is not the power motive that leads to corruption and tyranny, but rather how the power motive is channeled into behavior by other personality factors. Consequently, those charged with leader selection should place greater emphasis on how individuals with strong power motives differ in how they channel power. Doing so will support the selection of executives best equipped to deliver organizational performance.  相似文献

为解决常规钻井水力学公式对偏心流场计算结果与实际有所差别的问题,揭示大位移井偏心环空水力行为规律,基于fluent软件对幂律钻井液偏心环空紊流流动进行了数值模拟研究,分析偏心度、稠度系数、流性指数、屈服值、钻杆与钻头组合对流动规律的影响.结果表明,随偏心度、稠度系数、流性指数、屈服值、钻杆与钻头尺寸比例的增大,环空中宽间隙处的流速、压力逐渐增大,而窄间隙处的流速、压力逐渐减小.  相似文献

当前我国已经将决战脱贫攻坚、决胜全面建成小康社会作为主要的战略目标,为了实现这一目标,实现脱贫攻坚,电力保障是一个非常重要的因素。近年来我国全面推进农网改造升级工程。农网改造工程的接地施工质量的重要性毋庸置疑,但是农网改造工程的特殊性又使得接地质量的判断变得不好把握,本文从农网改造工程接地质量现状、防控措施等方面进行探讨。  相似文献

In the conventional economic wisdom, the notion of unique equilibria that are efficient and Pareto optimal dominates the modeling discourse. Hebert Simon proposed an alternative analytical framework where the notion of multiple and sustainable equilibria is critical. Multiple equilibrium is the crucial stylized fact of economic life that requires better understanding and modeling. Of particular significance, Simon touched on the importance of institutions and differential power relationships in affecting economic outcomes. But this modeling approach was not well developed by Simon. Following from his contributions, further develop the notion of multiple equilibria especially in the realm of production with an emphasis on x-efficiency theory. I bring to bear the importance of institutional parameters (including power relationships), culture, norms, ethics, and moral sentiments to the determination of economic outcomes. In the model developed here, boundedly rational decision-makers’ choices are contextualized and constrained by complex environmental factors. No one choice is either inevitable or economically efficient. A multiplicity of outcomes is possible and sustainable inclusive of those that are suboptimal. Much depends on individual preferences and institutional design. This has significant implication for institutional design and policy.  相似文献

构建上海合作组织命运共同体是中国政府提出的关于促进上海合作组织长远发展的重大倡议。由于上海合作组织命运共同体理念的提出时日尚短,学术界关于该理念的研究尚未全面启动。要使上海合作组织命运共同体理念成为一个有效的研究议题,不仅需要明晰上海合作组织命运共同体的具体内涵,而且需要将其纳入国际共同体、国际组织和大国外交等议题的研究,提炼出一些具有普遍性的理论命题。就攸关上海合作组织命运共同体构建的重大问题而言,至少需要回答上海合作组织命运共同体提出的理论与实践意义、上海合作组织命运共同体构建应遵循的基本路径、上海合作组织命运共同体构建的基础和条件、上海合作组织命运共同体构建面临的挑战与障碍、学术界能为上海合作组织命运共同体构建提供的对策建议等重大问题。在此过程中,学术界还需将其与周边命运共同体、人类命运共同体等家族相似性的概念纳入同一研究视域,以澄清上海合作组织命运共同体的内涵与外延,辨识上海合作组织命运共同体演变的动力与机制,并从理论层面提炼上海合作组织发展经验的特殊性与普遍性。  相似文献

Despite the widespread recognition of the paybacks of “going green” and “going clean,” limited research has focused on the impact of lean‐green strategy on firm growth. In this study, we contribute to strategy and environmental sustainability literatures by investigating the possibility that the influence on lean‐green strategy and firm growth is driven by different levels of industry competition, managerial power, and family ties. Using panel data from 732 firms in four major industrialized economies (the United States, Germany, France, and the United Kingdom), we found that lean‐green strategy positively relates to firm growth and this relationship is amplified at higher levels of competition, managerial power, and family ties. Theoretical and practical implications of the study are also discussed.  相似文献

While the literature on business power and global finance has illuminated the ways in which financial institutions limit the policy autonomy of states in developing countries, we know much less about the circumstances under which the power of financiers is undermined. In this article, I advance explanations of these circumstances by arguing that state access to natural resource revenues reduces the power of financial institutions and enhances the capacity of the state to pursue central bank policies which violate the interests of major financiers. I employ a case study of central bank policy in Nigeria to probe this argument and find evidence that supports the claim that whenever the Nigerian government's access to resource revenues increased, the state's capacity to diverge from financiers’ preferred central bank policies and to advance its own preferences increased as well. The analysis provides the basis for broader propositions about the policy space of developing countries vis-à-vis financial institutions and the variability of structural power.  相似文献

基于2003—2016年我国A股上市公司的经验数据,以企业表内列报的预计负债金额与表外附注中披露的或有事项频数为考察对象,实证检验了管理层权力对或有事项信息披露的影响。研究发现,管理层权力与表内列报的或有事项信息显著负相关,而与表外披露的或有事项信息显著正相关;进一步发现,随着环境不确定性的增加,管理层权力对企业表内预计负债列报的负向影响显著增强,而对表外或有事项披露的正向影响明显减弱。在当前外部环境瞬息万变、内部治理机制弱化的背景下,管理层可能会利用其控制权操控或有事项信息的披露方式,自我服务偏好明显。  相似文献

Finite mixtures offer a rich class of distributions for modelling of a variety of random phenomena in numerous fields of study. Using the sample interpoint distances (IPDs), we propose the IPD‐test statistic for testing the hypothesis of homogeneity of mixture of multivariate power series distribution or multivariate normal distribution. We derive the distribution of the IPDs that are drawn from a finite mixture of the multivariate power series distribution and multivariate normal distribution. Based on the empirical distribution of the IPDs, we construct a bootstrap test of homogeneity for other multivariate finite mixture models. The IPD test is applied to mixture models for matrix‐valued distributions and a test of homogeneity for Wishart mixture is presented. Numerical comparisons show that IPD test has accurate type I errors and is more powerful in most multivariate cases than the expectation–maximization (EM) test and modified likelihood ratio test.  相似文献
