Growth and decentralization have brought increasing conflict to many international NGOs, particularly between field and headquarters. This case study, written by the executive responsible for the activities portrayed, examines an attempt to define a clear new role for a headquarters department in a large, decentralized INGO focused on building unity of purpose. By ensuring that decentralized units of the organization took the leadership in related corporate initiatives whenever possible, with headquarters coordinating an inclusive process rather than implementing, unity was increased and tension reduced. Senior managers at the headquarters of growing, decentralized INGOs should find this case study relevant as they strive to maintain unity in the face of institutional fragmentation. 相似文献

This article describes the restructuring process currently underway at the United Church of Christ (UCC)—a 1.4 million member Protestant denomination. Three main questions are addressed: What are the central goals of the UCC restructure? What factors might explain the particular strategic direction pursued in UCC restructuring? and How might the UCC case inform recent thinking about the structure and performance of multisite nonprofits? 相似文献

Consider a decentralized, dynamic market with an infinite horizon and participation costs in which both buyers and sellers have private information concerning their values for the indivisible traded good. Time is discrete, each period has length δ, and, each unit of time, continuums of new buyers and sellers consider entry. Traders whose expected utility is negative choose not to enter. Within a period each buyer is matched anonymously with a seller and each seller is matched with zero, one, or more buyers. Every seller runs a first price auction with a reservation price and, if trade occurs, both the seller and the winning buyer exit the market with their realized utility. Traders who fail to trade continue in the market to be rematched. We characterize the steady‐state equilibria that are perfect Bayesian. We show that, as δ converges to zero, equilibrium prices at which trades occur converge to the Walrasian price and the realized allocations converge to the competitive allocation. We also show the existence of equilibria for δ sufficiently small, provided the discount rate is small relative to the participation costs. 相似文献

Regarding the effect of product variety on purchase probability, there exist findings which demonstrate a positive effect
of variety for small assortments and a negative effect of variety for large assortments. Despite these results, little evidence
exists about the causal mechanism of this effect. We conduct a field study among German consumer electronics customers to
investigate the previously proposed constructs of anticipated product utility, anticipated regret and evaluation costs. The
results suggest that anticipated regret and evaluation costs play a powerful role in explaining the negative link between
variety and purchase probability for high variety assortments. Anticipated product utility on the other hand serves to explain
part of the positive causality for low variety assortments. The results obtained give rise to recommendations for the planning
of assortments.

Recurrent events in clinical trials have typically been analysed using either a multiple time-to-event method or a direct approach based on the distribution of the number of events. An area of application for these methods is exacerbation data from respiratory clinical trials. The different approaches to the analysis and the issues involved are illustrated for a large trial (n = 1465) in chronic obstructive pulmonary disease (COPD). For exacerbation rates, clinical interest centres on a direct comparison of rates for each treatment which favours the distribution-based analysis, rather than a time-to-event approach. Poisson regression has often been employed and has recently been recommended as the appropriate method of analysis for COPD exacerbations but the key assumptions often appear unreasonable for this analysis. By contrast use of a negative binomial model which corresponds to assuming a separate Poisson parameter for each subject offers a more appealing approach. Non-parametric methods avoid some of the assumptions required by these models, but do not provide appropriate estimates of treatment effects because of the discrete and bounded nature of the data. 相似文献

This article presents a quantitative content analysis of 10,473 comments from two opposing online petitions related to the legal status of a section of the penal code in Singapore used to ban sex between men. Results indicate numerous significant differences in how the two sides discussed the law and its significance. In particular, they used different types of arguments to support their views and expressed different kinds of concerns over the potential impact of changing or maintaining the law. The patterns of language use seem to reflect distinctly different approaches to the debate and suggest the difficulty of finding common ground amid this contentious social issue, but they also reveal similarities to how Western cultures have framed the debate. 相似文献

We present two studies that examine the effects of psychological entitlement on employees' ratings of abusive supervision and their behavioral reactions to these perceptions. Study 1 indicated that entitlement was positively associated with ratings of abusive supervision. Perceived abuse was, in turn, associated with upward undermining behaviors and organizational deviance. In Study 2, we re-examined the hypothesized relationships using paired data from employees and their coworkers. The results replicated those from the first study and showed that entitled employees rated supervisors as more abusive than coworkers who shared the same supervisors. Although this variance is likely driven by a combination of perceptual distortion and actual abusive behaviors, the ultimate implication is that psychologically entitled employees are prone to feel that they are victims of abuse and to react in undesirable ways. 相似文献
