Questionnaire data obtained from 97 supervisory and nonsupervisory employees representing the Production, Production Services, Marketing, and Administration departments of an Israeli metal production plant were used to test the relationship between selected personal and organizational attributes and work related misbehavior. Following Vardi and Wiener's (1996) framework, Organizational Misbehavior (OMB) was defined as intentional acts that violate formal core organizational rules. We found that there was a significant negative relationship between Organizational Climate and OMB, and between the Organizational Climate dimensions (Warmth and Support, and Reward), and OMB. Also, the activities of misbehavior reported by both managers and employees were negatively related to the Rules, Instrumental and Caring dimensions of Ethical Climates as defined by Victor and Cullen (1988). 相似文献

This article reviews a new program established to provide modern modes of oncologic therapy to Arab cancer patients in the West Bank. The population of this region is distinguished by its fatalistic and traditional attitudes, and communication via word of mouth is prevalent. Therefore, the social system can be considered as one of traditional norms discouraging the adoption of new ideas. Demonstration effects and face-to-face communication proved effective in bringing about social change in health patterns. 相似文献

The paper reports a study of the operation of the breeding system in the milk herd in Israel. Basic notions in quantitative genetics are explained and incorporated in a simulation model which is used to illustrate and analyse the selection process. Particularly emphasised are the traits common to selection and other research and development effort; among them, search, limited information, and biological and technical constraints. Differential technical changes affected the structure of the milk producing industry and its measured productivity; these effects are discussed in the last part of the paper. 相似文献

Simple search methods for finding a Nash equilibrium 总被引:1,自引:1,他引:0
We present two simple search methods for computing a sample Nash equilibrium in a normal-form game: one for 2-player games and one for n-player games. Both algorithms bias the search towards supports that are small and balanced, and employ a backtracking procedure to efficiently explore these supports. Making use of a new comprehensive testbed, we test these algorithms on many classes of games, and show that they perform well against the state of the art—the Lemke–Howson algorithm for 2-player games, and Simplicial Subdivision and Govindan–Wilson for n-player games. 相似文献

The multiplicity problem is evident in the simplest form of statistical analysis of gene expression data – the identification of differentially expressed genes. In more complex analysis, the problem is compounded by the multiplicity of hypotheses per gene. Thus, in some cases, it may be necessary to consider testing millions of hypotheses. We present three general approaches for addressing multiplicity in large research problems. (a) Use the scalability of false discovery rate (FDR) controlling procedures; (b) apply FDR-controlling procedures to a selected subset of hypotheses; (c) apply hierarchical FDR-controlling procedures. We also offer a general framework for ensuring reproducible results in complex research, where a researcher faces more than just one large research problem. We demonstrate these approaches by analyzing the results of a complex experiment involving the study of gene expression levels in different brain regions across multiple mouse strains. 相似文献

Medical technology diffusion and its effect on the modern hospital and on the rising costs of medical care is an issue which receives considerable attention from economists and policy analysts. In this paper a different approach is used to understand this phenomenon. We present the decision of a single hospital, whether or not to adopt an advanced technology system, using the concept of a noncooperative, nonzero sum game. Such presentation provides us with more insight on the conflict in which hospitals find themselves; the "catch" which pushes them to purchase more and more sophisticated and expensive technology in the hope that they will be able to successfully compete with other hospitals. The situation is further complicated by the existence of another "hidden" player--society, whose goals may differ from those of any individual hospital and even from the collective interests of the hospital sector. Possible conflicts that may exist and suggested solutions for each participant are presented and their policy implication are discussed. 相似文献

In this non-technical review of agricultural research the author points to the geographical and economic distribution of research efforts, the problems of transfers of knowledge and technologies, consequent adjustment problems, and resource allocation in agricultural research. 相似文献

Equilibrium joining probabilities for an M/G/1 queue 总被引:1,自引:0,他引:1
We study the customers' Nash equilibrium behavior in a single server observable queue with Poisson arrivals and general service times. Each customer takes a single decision upon arrival: to join or not to join. Furthermore, future regrets are not allowed. The customers are homogenous with respect to their linear waiting cost and the reward associated with service completion. The cost of joining depends on the behavior of the other customers present, which naturally forms a strategic game. We present a recursive algorithm for computing the (possibly mixed) Nash equilibrium strategy. The algorithm's output is queue-dependent joining probabilities. We demonstrate that depending on the service distribution, this equilibrium is not necessarily unique. Also, we show that depending on the service time distribution, either the ‘avoid the crowd’ phenomenon or the ‘follow the crowd’ phenomenon may hold. 相似文献

The role of agriculture in the Israeli economy has been declining, and a combination of essential trends has resulted in the emergence of tourism as alternative sources of economic growth in rural areas. These changes have created a new situation, in which tourism-related developments in the rural areas of Israel have become part of the activities of many farm owners. Thus, the Israeli rural environment is a single, tightly coupled system and should be analysed as such. The growth of rural tourism in the Israeli agricultural sector raises several questions, addressing whether rural tourism and farming are synergetic, and the effects of tight coupling between tourism development and agricultural processes. This article presents a simulation model of the coupling effects in which tourism development and agricultural processes are tightly coupled. Our model examined large numbers of different scenarios and the possible outcomes of a decision the farm owner takes in a routine situation of uncertainty. A typical Israeli farm owner embarks on tourism development activities mainly because of stress. Our model shows that adding tourism activities does not increase profit dramatically, but it does increase the variance of profit, which means greater exposure to risks. 相似文献
