A within-subject ABAB reversal design was utilized to investigate the effects of graphic feedback and goal setting on employee closing task completion. Goal setting was contingent upon baseline performance and graphic feedback was posted weekly. It was found that goal setting and graphic feedback improved employee closing task completion. 相似文献

This paper presents a model and an algorithm for scheduling a system in which parts are processed through a chemical processing tank line. The tank line is equipped with one piece of material-handling equipment. The tank line is modelled with a mixed integer linear programming formulation. The formulation is then used to develop a heuristic algorithm. The algorithm generates the optimum or near optimum schedule and is easy to apply in practice where no defectives are permitted. 相似文献

Optimal scheduling of shopfloor activities in an environment of discrete part manufacturing is discussed. The scheduling problem is a well known NP complete one. The main part, the sequencing problem, has been tackled using two techniques: virtual resources identification and taboo search heuristics. The first approach allowed the authors to reduce the complexity of the sequencing from a job shop to a general flow shop problem. On the other hand, the search for an optimal solution, with respect to a fixed strategy, has been achieved via the taboo search. A synthesis of the results of a large number of tests is presented as well as the results of an application to a real case. The latter is shown in comparison with the output of the system being presently used in the examined factory. 相似文献

The objective of this study is to examine the impact of a short-term international experience, which is designed to address the conditions outlined in Allport’s (Allport, G.W. 1954. The Nature of Prejudice. New York: Perseus Book Group) contact hypothesis, on each of the four factors which make up cultural intelligence (CQ). A sample of 135 university students was broken up into test and control groups. The results for the test group suggest that the short-term experience ranging from 7 to 12 days within a structured study abroad service programme, including modest pre-trip preparation, found a significant increase in each of the four factors of CQ. At the same time, there was no significant change in the control group. Implications for human research development research and practice as well as limitations and suggested areas for future research are discussed. 相似文献

Despite international terrorism's increasing relevance for international business, the effects of terrorism that confront employees during assignments abroad have hardly been investigated. Applying a stress perspective, this article analyzes the impact of terrorism-induced stress on attitudes and the performance of expatriates. Employing data from 143 expatriate managers in high-risk countries, the study shows that several terrorism-related stressors create a significant stress level for the individual, causing negative work attitudes and attitudes towards host country nationals (disaffection). This eventually leads to worse performance. We applied partial least squares (PLS) structural equation modeling (SEM) to analyze the entire impact path and found substantial support for our hypotheses. Of all the relevant stressors, intra-family conflicts due to terrorism have the greatest impact. 相似文献

The initial version (v1) of the Fish Invasiveness Scoring Kit (FISK) was adapted from the Weed Risk Assessment of Pheloung, Williams, and Halloy to assess the potential invasiveness of nonnative freshwater fishes in the United Kingdom. Published applications of FISK v1 have been primarily in temperate‐zone countries (Belgium, Belarus, and Japan), so the specificity of this screening tool to that climatic zone was not noted until attempts were made to apply it in peninsular Florida. To remedy this shortcoming, the questions and guidance notes of FISK v1 were reviewed and revised to improve clarity and extend its applicability to broader climatic regions, resulting in changes to 36 of the 49 questions. In addition, upgrades were made to the software architecture of FISK to improve overall computational speed as well as graphical user interface flexibility and friendliness. We demonstrate the process of screening a fish species using FISK v2 in a realistic management scenario by assessing the Barcoo grunter Scortum barcoo (Terapontidae), a species whose management concerns are related to its potential use for aquaponics in Florida. The FISK v2 screening of Barcoo grunter placed the species into the lower range of medium risk (score = 5), suggesting it is a permissible species for use in Florida under current nonnative species regulations. Screening of the Barcoo grunter illustrates the usefulness of FISK v2 as a proactive tool serving to inform risk management decisions, but the low level of confidence associated with the assessment highlighted a dearth of critical information on this species. 相似文献

Social Amplification of Wildfire Risk: The Role of Social Interactions and Information Sources 总被引:2,自引:0,他引:2
Hannah Brenkert‐Smith Katherine L. Dickinson Patricia A. Champ Nicholas Flores 《Risk analysis》2013,33(5):800-817
Wildfire is a persistent and growing threat across much of the western United States. Understanding how people living in fire‐prone areas perceive this threat is essential to the design of effective risk management policies. Drawing on the social amplification of risk framework, we develop a conceptual model of wildfire risk perceptions that incorporates the social processes that likely shape how individuals in fire‐prone areas come to understand this risk, highlighting the role of information sources and social interactions. We classify information sources as expert or nonexpert, and group social interactions according to two dimensions: formal versus informal, and generic versus fire‐specific. Using survey data from two Colorado counties, we empirically examine how information sources and social interactions relate to the perceived probability and perceived consequences of a wildfire. Our results suggest that social amplification processes play a role in shaping how individuals in this area perceive wildfire risk. A key finding is that both “vertical” (i.e., expert information sources and formal social interactions) and “horizontal” (i.e., nonexpert information and informal interactions) interactions are associated with perceived risk of experiencing a wildfire. We also find evidence of perceived “risk interdependency”—that is, homeowners’ perceptions of risk are higher when vegetation on neighboring properties is perceived to be dense. Incorporating social amplification processes into community‐based wildfire education programs and evaluating these programs’ effectiveness constitutes an area for future inquiry. 相似文献

正式控制的局限性、企业对客户关系的重视以及销售人员素质的提高,使得企业越发重视销售人员的非正式控制,但是关于非正式控制对销售人员绩效和客户关系质量影响的研究还较少,非正式控制时销售人员绩效和客户关系质量的作用机制与作用效果还没有得到有效验证.本文在理论分析的基础上,建立了非正式控制影响销售人员绩效和客户关系质量的概念模型和研究假设,并进行了实证检验.结果表明:非正式控制对绩效既有直接影响,也有间接影响,其中间接影响的中介变量为角色明晰性:非正式控制只能通过角色明晰性和情感性承诺对客户关系质量产生间接影响,而对客户关系质量的直接影响不显著.非正式控制对角色明晰性、情感性承诺、绩效、客户关系质量影响的总效应分别为0.38、0.51、0.48、0.48.实证研究结果为企业强化销售人员的非正式控制提供了理论支撑,对其他员工管理控制的研究与实践也具有借鉴意义. 相似文献

This paper develops the idea that following rules of good OR practice is necessary, but not sufficient for ethical OR. Several challenges of introducing ethical aspects into OR are discussed, evidencing difficulties and ambiguities in the relationship to be established between the OR practitioner and his/her clients, decision-makers or stakeholders. It shows that neither analysis nor modelling work nor the choice of analytical tools is entirely ethically neutral; incomparability, incommensurability and incertitude must be dealt with. The purpose of this article is to detail several difficulties or dilemmas an OR practitioner may be confronted with in the course of his or her assignment. In such situations, following rules of good practice may not be sufficient to indicate how to act in a morally good way. This paper aims at stimulating reflection by structuring the debate; it may leave the reader unsettled—unsettlement being a result and even aim of many discussions in moral philosophy. 相似文献
