Face-to-face communication is investigated as an efficiency-enhancing mechanism in experimental common-pool resource environments in which the appropriation activities of outside appropriators create coordination and monitoring problems for the communicating group. We identify three distinct problems that can threaten successful collective action. Outsiders respond strategically to reductions in appropriation by cooperating group members. Members of the communicating group deviate from agreements more frequently when monitoring is imperfect and over appropriation can be blamed on outsiders. Groups that are allowed to communicate anticipate the potential problems and have difficulty reaching agreements or committing to a specific appropriation rule. 相似文献

Within the inferential context of predicting a distribution of potential outcomes P[y(t)] under a uniform treatment assignment t ∈ T, this paper deals with partial identification of the α‐quantile of the distribution of interest Qα[y(t)] under relatively weak and credible monotonicity‐type assumptions on the individual response functions and the population selection process. On the theoretical side, the paper adds to the existing results on non‐parametric bounds on quantiles with no prior information and under monotone treatment response (MTR) by introducing and studying the identifying properties of α‐quantile monotone treatment selection (α‐QMTS), α‐quantile monotone instrumental variables (α‐QMIV) and their combinations. The main result parallels that for the mean; MTR and α‐QMTS aid identification in a complementary fashion, so that combining them greatly increases identification power. The theoretical results are illustrated through an empirical application on the Italian returns to educational qualifications. Bounds on several quantiles of ln(wage) under different qualifications and on quantile treatments effects (QTE) are estimated and compared with parametric quantile regression (α‐QR) and α‐IVQR estimates from the same sample. Remarkably, the α‐QMTS & MTR upper bounds on the α‐QTE of a college degree versus elementary education imply smaller year‐by‐year returns than the corresponding α‐IVQR point estimates.

Survey calibration (or generalized raking) estimators are a standard approach to the use of auxiliary information in survey sampling, improving on the simple Horvitz–Thompson estimator. In this paper we relate the survey calibration estimators to the semiparametric incomplete‐data estimators of Robins and coworkers, and to adjustment for baseline variables in a randomized trial. The development based on calibration estimators explains the “estimated weights” paradox and provides useful heuristics for constructing practical estimators. We present some examples of using calibration to gain precision without making additional modelling assumptions in a variety of regression models. 相似文献

abstract This study assesses the prevalence of workplace bullying in a sample of US workers, using a standardized measure of workplace bullying (Negative Acts Questionnaire, NAQ), and compares the current study's prevalence rates with those from other bullying and aggression studies. The article opens by defining bullying as a persistent, enduring form of abuse at work and contrasting it with other negative workplace actions and interactions. Through a review of the current literature, we propose and test hypotheses regarding bullying prevalence and dynamics relative to a sample of US workers. After discussing research methods, we report on the rates of bullying in a US sample, compare these to similar studies, and analyse the negative acts that might lead to perceptions of being bullied. Based upon past conceptualizations, as well as research that suggests bullying is a phenomenon that occurs in gradations, we introduce and provide statistical evidence for the construct and impact of bullying degree. Finally, the study explores the impact of bullying on persons who witnessed but did not directly experience bullying in their jobs. 相似文献

The role of the nurse leader in patient safety can be characterized as follows: to establish the right culture; to infuse that culture with shared leadership so that the expert voice at the bedside is really defining the work; to possess the competencies necessary to coordinate and advance this complex initiative; and to forge both internal and external partnerships, because we will not be able to do this work alone. To further the work on this topic, nurse leaders who participated in the Nursing Leadership Congress are committed to identifying additional resources to help nurse leader colleagues drive patient safety efforts throughout their organizations. 相似文献

Drawing on signaling theory, we hypothesize that a firm's reputation is shaped by its own market actions and the actions of its industry rivals. We view market actions as signals that convey information about the underlying competencies of firms and influence stakeholder evaluations of them. We find that the total number of a firm's market actions, the complexity of its action repertoire, the time lag in rivals' responses to its actions, and the similarity of its repertoire with those of its rivals positively affect its reputation. These results suggest that a firm's reputation is influenced both by its own actions and by its rivals' actions. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

In the early years of the twentieth century, rural America faced a population crisis as young people increasingly left farms for cities. Progressive reformers responded to this crisis with various suggestions meant to more firmly attach youngsters to their rural roots. Among the many solutions advocated were rural youth organizations. The Farm Boy Cavaliers of America, which also enrolled girls, pursued a more innovative path than most, emphasizing not only entertainment and instruction, but also a high degree of economic education and independence for farm children. The program offered an alternative to the Boy Scouts, which Dexter D. Mayne, the organization's founder, believed to be unsatisfactory and inappropriate for farm youth. Ultimately, the organization may have promoted too much freedom for the rural youth, advocating behavior that parents could not approve of or afford in the cash-strapped early days of the century. 相似文献

This paper contrasts findings from a quantitative survey with those from a cognitive interviewing follow-up investigation on a subset of the same respondents. The data were gathered as part of a larger study to explore measurement error across three modes of data collection, but this paper focuses on the question format experiments rather than the mode effects part of the larger study. Three examples are presented which demonstrate how cognitive interviewing can cast new light on quantitative results by increasing the accuracy of the inferences made. These include instances where: (1) quantitative indicators of poor respondent behaviour (e.g., acquiescence bias on agree/disagree questions) are over-estimates, (2) similar quantitative response distributions across satisfaction and behavioural questions (from a fully-labelled versus end-labelled experiment) imply similar respondent satisficing behaviour, but cognitive interviews show that different response processes are at work and (3) unlikely quantitative findings (from an experiment comparing 3 vs. 7 or 8 response options) could easily be dismissed as due to chance but were instead the result of unforeseen respondent difficulties. The paper concludes with a discussion of the value of using a cognitive interviewing follow-up study as a tool in the interpretation of ambiguous quantitative findings. 相似文献

This paper contributes to the emerging literature on reshoring by taking a value-driven enquiry into the renewal of supply chain strategy. It enhances the understanding of the use of reshoring in generating the value demanded by a changing business model. An iconic British high-end clothing brand, Burberry, is the chosen case study to explore the recent move towards reshoring because its changes of leadership, business model and evolving supply chain strategy from 1997 to early 2016 provide a timely and pertinent context. Burberry has continued to realign its business towards a brand-led and customer-centric model along with restoring its corporate heritage and core brand values. The changes in Burberry’s business model triggered the need to renew and realign its supply chain strategy through consolidating and rebuilding manufacturing activities back in the UK, in order to support its brand repositioning as quintessentially British and the company’s refocus on heritage products. The increased managerial control in the supply chain together with the close proximity of design and manufacture enables the promise of quality and brand provenance to be fulfilled. The renewal of Burberry’s supply chain strategy has contributed to an increase in revenues and brand values. These findings suggest that the renewal of supply chain strategy through reshoring and increasing control in supply chain operations can enhance value and firm competitiveness. 相似文献
