ABSTRACT

There is a substantial literature on how to deliver feedback to change performance. However, to date no research has been conducted on teaching employees how to effectively receive feedback, even though employee behavior during a feedback session could moderate the effects of feedback. Thus, we developed a list of skills that should be exhibited by an employee while receiving verbal feedback. We then evaluated their acquisition after behavioral skills training using a nonconcurrent multiple-baseline design across participants. The results showed that participants were able to acquire and maintain appropriate feedback receiving behavior.  相似文献

ABSTRACT This paper uses themes from political ecology to develop insights into the billion dollar shrimp aquaculture sector in Thailand. We find that corporations can exercise only limited control over shrimp production and that there is no clear trend toward larger operations. We explain the continued viability of small owner-operated farms by looking at how shrimp farming is located in physical and social space, and at the ability of owner-operators to work within the highly unstable socio-ecological processes of shrimp production. We also find that shrimp farming has induced a spatially-uneven increase in state territorial regulation. The spatial distribution of regulation is shaped by differences in how landscapes become politicized, and the degree of jurisdictional clarity. We conclude that industry self-regulation has limited prospects for containing the social and environmental problems of shrimp farming in Thailand, but that expanded state regulation that mobilizes the participation of local people might be effective.  相似文献

Although soldiers and relief workers traditionally have engaged in conflicting missions—killing versus saving lives—recent peacekeeping operations have required the two groups to work together on humanitarian efforts. Interviews with aid workers in Bosnia and in Haiti reveal that this traditionally antimilitary population has come to support military interventions in their regions. They have developed a cooperative relationship with the military despite lingering doubts and persistent cultural differences. This recent shift in attitudes demonstrates that the concept of task cohesion, developed from studies of small-group dynamics, can be applied at the organizational level. Organizations that share a common goal and that depend on one another to reach that goal can develop a cooperative relationship and yet retain distinct organizational memberships and cultures.  相似文献

The branching structure of inflorescences of the cultivated strawberry ( Fragaria × ananassa Duch.) is very variable. This paper demonstrates that some aspects of this variability are well described by a simple stochastic model of branching that has two adjustable parameters. The model is shown to provide a good fit to data from a set of almost 700 inflorescences of the cultivar Elsanta, collected over two successive years. For one parameter the maximum likelihood estimator is a moment estimator which is fully efficient even if the detailed branching structure of the inflorescences is not recorded. This parameter provides a convenient summary of branching vigour. The maximum likelihood estimator of the second parameter must be determined iteratively and can be quite inefficient unless the full branching structure is recorded. The model demonstrates that branching structure is affected by the order in which inflorescences emerge on the plant.  相似文献

Monitoring, as an important function for boards of directors in both the private and nonprofit sectors, receives widespread attention throughout the empirical (Chait, Holland, and Taylor, 1996; Eisenhardt, 1989; Golden‐Biddle and Rao, 1997; Kosnik, 1987) and normative literature (Axelrod, 1994; Block, 1998; Carver, 1997; Houle, 1997; Ingram, 1989). Despite the consensus about the significance of this crucial board responsibility, scholars know little about the ways in which a nonprofit board actually performs its monitoring function. In this article I report on an empirical study of the monitoring behavior of twelve nonprofit boards of directors. Agency theory provides the framework for this analysis. I show that the way in which individual board members define their relationship with the chief executive and understand the scope of the monitoring function influences how, or if, they monitor agency action. The findings also show that, given ambiguous rules of accountability and unclear measures of performance, nonprofit board members tend to monitor in ways that reflect their professional or personal competencies rather than paying attention to measures that would indicate progress toward mission‐related goals and initiatives.  相似文献

Applying Weber's theorizing on action and stratification, this study examines whether the early 20th-century extinction of half of the medical schools in the United States resulted from actions intended to serve class, status, and party interests by achieving social closure. Analyses reveal closure intentions in the school ratings assigned by the American Medical Association, although not in the recommendations in the 1910 Carnegie-sponsored Flexner report. In contrast to claims that schools failed largely because of economic exigencies, analyses indicate that failures were influenced by the AMA's and Flexner's assessments, as well as by state regulatory regimes and school characteristics.  相似文献

We introduce health technology assessment and evidence synthesis briefly, and then concentrate on the statistical approaches used for conducting network meta-analysis (NMA) in the development and approval of new health technologies. NMA is an extension of standard meta-analysis where indirect as well as direct information is combined and can be seen as similar to the analysis of incomplete-block designs. We illustrate it with an example involving three treatments, using fixed-effects and random-effects models, and using frequentist and Bayesian approaches. As most statisticians in the pharmaceutical industry are familiar with SAS? software for analyzing clinical trials, we provide example code for each of the methods we illustrate. One issue that has been overlooked in the literature is the choice of constraints applied to random effects, and we show how this affects the estimates and standard errors and propose a symmetric set of constraints that is equivalent to most current practice. Finally, we discuss the role of statisticians in planning and carrying out NMAs and the strategy for dealing with important issues such as heterogeneity.  相似文献

Community Amenity Measurement for the Great Fly-Over Zones   总被引:1,自引:0,他引:1  
The purpose of this paper is to provide an alternative operationalization of amenities that does not privilege certain kinds of natural resources and climatic conditions and that can be used for assessing the quality of life in small towns. The amenity inventory presented here extends previous literature by including a broad range of amenities (natural resource, indoor and outdoor built recreational facilities, public and private services, and downtown amenities). The community level of analysis and small town focus are also unique. The inventory uses both secondary data from public sources and primary data that can be gathered by researchers or community residents. Therefore, in addition to the scholarly contribution of the inventory, the process of defining and assessing community amenities may be a valuable tool for building interpersonal relationships within communities, generating community spirit, and developing strategies for enhancing the local quality of life.  相似文献
