Utilizing affective events theory (Weiss & Cropanzano, 1996), the current study unravels how and when pseudo-transformational leaders promote contempt, avoidance, and aggression. Specifically, we examined whether pseudo-transformational leadership enforces feelings of contempt, which, in turn, fosters interaction avoidance and covert aggression in followers. We hypothesized that contempt also has an indirect effect that is contingent on levels of epistemic motivation of followers. By adopting a multi-wave research design, we gathered data from 277 employees of the service sector of Pakistan. The results signified that followers of pseudo-transformational leaders feel contemptuous of them and respond with interaction avoidance and indirect aggression. Further, we found that the impact of pseudo-transformational leadership on contempt was more pronounced in individuals with higher levels of epistemic motivation. We believe that this study opens up a new avenue in the pseudo-transformational leadership literature by highlighting the mechanism and conditions under which such leaders are deleterious for organizations. 相似文献

There is a considerable debate in terms of opportunities and challenges about the presence of refugees in the neighbouring host countries. Most of the existing discourse has focused only on their humanitarian and security implications. This article, on the other hand, seeks to uncover this issue through a purely economic lens, focusing on the economic impact of more than three million Afghan refugees in Pakistan. Utilizing data for the period 1979–2014 and the ARDL bounds testing approach, we arrive at few important conclusions. The empirical results indicate that Afghan refugees have a strong negative impact on economic growth in Pakistan. The effect holds in both the short run and the long run, suggesting that the influx of refugees lowers real economic activity in the country. Ultimately, the study implies that hosting refugees can never be a boon to Pakistan's economy. 相似文献

Pricing and Replenishment of Competing Perishable Product Variants under Dynamic Demand Substitution
Arvind Sainathan 《Production and Operations Management》2013,22(5):1157-1181
I consider pricing and ordering decisions faced by a retailer selling a perishable product with a two‐period shelf life over an infinite horizon. In the first period, the product is “new”; in the next, it becomes “old.” The new product is perceived by customers to have a higher quality than the old product. Every period, the retailer makes three decisions: prices for the new and old products and how much new product to order. I first show, with some simple cases, that demand uncertainty can make the sale of the old product profitable. I then consider a more realistic case with dynamic demand substitution among customers. I recognize that the retailer's decisions may be constant or may vary across different periods, under different contexts. For instance, varying the price of the new product can sometimes be difficult due to the negative impact it generates among customers. I find that (i) the benefit obtained from selling the old product with constant decisions is much higher than the benefit from allowing all the decisions to vary; (ii) the former benefit increases with a higher procurement cost, a higher quality of the new product, and higher demand volatility; however, the latter benefit is non‐monotone in these parameters; (iii) most of the latter benefit can be obtained by just changing the order quantity; and (iv) as the inventory of the old product increases, when all the decisions vary, the optimal price of the new product may increase or decrease. 相似文献

Previous research on mass customization (MC) has focused on what it is and how it is implemented. In this study we examine when MC is an appropriate strategy for firms to follow by scrutinizing the effects of three environmental uncertainty variables (demand uncertainty, competitive intensity, and supply chain complexity) on the MC–performance relationship. Specifically, we distinguish the direct effect of environmental uncertainty on MC ability and the moderation effect of environmental uncertainty on MC ability's impact on customer satisfaction. We examine six competing hypotheses using data collected from 266 manufacturing plants. Our results show that competitive intensity has a direct positive impact on MC ability. However, demand uncertainty moderates the relationship between MC ability and customer satisfaction, and the direct and positive relationship between MC ability and customer satisfaction holds only when customer demand is highly uncertain. Supply chain complexity neither has a direct relationship with MC, nor moderates the MC–performance relationship. Implications of these research findings are discussed and future research directions are identified. 相似文献

注意力是促使语言输入转化为内在知识的必要和充分条件。本研究通过为期一学期的教学实验,对英语词块强化注意教学模式和传统教学模式的教学效果进行了比较,探究了词块强化注意教学模式的有效性。结果发现:该模式教学能显著提高词块应用水平、英语综合水平和作文水平,而对听力和阅读理解水平的提高则无明显效果。研究证实:通过教学手段提高和强化输入词块的频率与突显程度、以及设计以词块输出为中心的教学任务可以促进词块由输入转变成内在知识、提高语言加工深度,从而提高语言产出水平。 相似文献

An implicit assumption in distributing and coordinating work among independent organizations in a supply chain is that a focal organization can use financial or contractual mechanisms to enforce compliance among the other organizations in meeting desired performance objectives. Absent contractual agreement or financial gain, there is little incentive for independent organizations to coordinate their process improvement activities. In this study, we examine a health care supply chain in which the work is distributed among independent organizations. We use a detailed case study and an abductive reasoning approach to understand how and why the independent organizations choose to coordinate and collaborate in their work. Our study makes two contributions to the literature. First, we use well‐established lean principles to explain how independent organizations achieve superior performance despite highly uncertain and variable customer demand—a context considerably different from the origins of lean principles. Second, we forward relational coordination theory to explain why the organizations in this decentralized supply chain coordinate their work. Relational coordination includes the use of shared goals, shared knowledge, and mutual respect for one another's work as primary mechanisms to explain process improvement in the absence of any contractual incentives. Our study constitutes a first step in generating theory for work design and its improvement in decentralized supply chains. 相似文献

Given an inverse Gaussian distribution I(.μ,a2μ) with known coefficient of variation a, the hypothesis HO: .μ <ce:glyph name="dbnd6"/> μo is tested against H1: μ <ce:glyph name="dbnd6"/> μ1 using the sequential probability ratio test. The maximum of the expected sample number is shown to occur when μ is approximately equal to the geometric mean of μoand μ1 and it is shown that this maximum value depends on .μo and μ1 only through their ratio. It is observed that the test can be used to discriminate between two one-sided hypotheses. 相似文献
