The popular press and academic research has focused primarily on the characteristics of corporate leaders. Subordinates have been studied much less frequently than leaders and yet they play a pivotal role in destructive leadership processes. An area holding significant potential to bring clarity to subordinates?? ability to withstand (or succumb) to pressures from superiors is dispositional affect. In our exploratory study, we examine how specific affective states influence subordinates?? unethical behavior. We performed an experiment with 63 mid-level managers having significant work experience. Participants were given ethical scenarios and asked to assess their intentions to comply with their superiors?? requests to engage in unethical conduct. The participants also completed the positive affect negative affect schedule (PANAS) which provides measures of affective states. Our results provide support for theory-based predictions. The findings of our study make important contributions and have implications to both practice and theory. First, we identify certain affective states that encourage subordinates to adopt the behavior of a conformer or colluder and thus be susceptible to their superiors?? unethical directives. Second, our results suggest the need for training programs to assist employees in managing affect in the work place and consideration of organizational changes that provide a culture of empowerment of its employees. Third, unlike a large majority of prior research, we measured naturally occurring affective states rather than providing a contrived (and potentially exaggerated) triggering event to elicit affective states. Fourth, we examined specific affective states rather than examining only general positive and negative valence categories.  相似文献

We examine whether, and to what extent, the introduction of trading in share futures contracts on individual stocks (i.e., individual share futures, or ISFs) has impacted on the systematic risk and volatility of the underlying shares. The use of ISFs allows a unique experimental design that complements existing work on index futures. Our major findings are as follows. First, we found a general reduction in systematic risk on individual stocks after the listing of futures. Second, we found evidence of a decline in unconditional volatility. Third, we found mixed evidence concerning the impact on conditional volatility. Fourth, the introduction of futures was found to impact on the market dynamics, as reflected by a change in the asymmetric volatility response, although the direction of that change is stock‐specific. In general, the results point to a number of features that are case‐specific and provide new insights into the mixed results that are typical of existing studies. © 2001 John Wiley & Sons, Inc.

This paper discusses legal and ethical issues related to genetic screening. It is argued that persons identified with actual or perceived deleterious genetic markers are protected by the American with Disabilities Act of 1990 and the Civil Rights Act of 1991, if members of a protected group, regardless of whether or not they are currently ill. However, legislation may not protect all employees in all scenarios, in which case, ethical principles should guide decision-making. In doing so a model of preventive ethics is proposed to better understand the multiple levels on which this issue resides.  相似文献

Fallback Bargaining   总被引:2,自引:2,他引:2  
Under fallback bargaining, bargainers begin by indicating their preference rankings over alternatives. They then fall back, in lockstep, to less and less preferred alternatives – starting with first choices, then adding second choices, and so on – until an alternative is found on which all bargainers agree. This common agreement, which becomes the outcome of the procedure, may be different if a decision rule other than unanimity is used. The outcome is always Pareto-optimal but need not be unique; if unanimity is used, it is at least middling in everybody's ranking. Fallback bargaining may not select a Condorcet alternative, or even the first choice of a majority of bargainers. However, it does maximize bargainers' minimum satisfaction. When bargainers are allowed to indicate impasse in their rankings – below which they would not descend because they prefer no agreement to any lower-level alternative – then impasse itself may become the outcome, foreclosing any agreement. The vulnerability of fallback bargaining to manipulation is analyzed in terms of both best responses and Nash equilibria. Although a bargainer can sometimes achieve a preferred outcome through an untruthful announcement, the risk of a mutually worst outcome in a Chicken-type game may well deter the bargainers from attempting to be exploitative, especially when information is incomplete. Fallback bargaining seems useful as a practicable procedure if a set of reasonable alternatives can be generated. It leapfrogs the give-and-take of conventional bargaining, which often bogs down in details, by finding a suitable settlement through the simultaneous consideration of all alternatives.  相似文献

We present work concerning the formal specification of business processes. It is of substantial benefit to be able to pin down the meaning of business processes precisely. This is an end in itself, but we are also concerned to do so in order that we might prove properties about the business processes that are being specified. It is a notable characteristic of most languages for representing business processes that they lack a robust semantics, and a notable characteristic of most commercial Business Process Management products that they have no support for verification of business process models. We define a high-level meta-model, called Liesbet , for representing business processes. The ontological commitments for Liesbet are sourced from the YAWL workflow patterns, which have been defined from studies into the behavioural nature of business processes. A formal characterisation of Liesbet is provided using Milner’s Calculus of Communicating Systems (CCS). In this article, we omit some of the technical details of this characterisation and instead present the essential features by means of an abstract machine language, called LCCS. We also explain how we have facilitated the verification of certain properties of business processes specified in Liesbet , and discuss how Liesbet supports the YAWL workflow patterns. We include a simple three-part example of using Liesbet .  相似文献

This article applies inductive analytic techniques to identify and elaborate on two recurring themes that underpin the core puzzle of entrepreneurship research — where entrepreneurial opportunities come from. The first theme is the unique role of imprinting, or the profound influence of social and historical context in constraining the perceptual apparatus of entrepreneurs and delimiting the range of opportunities for innovation available to them. Second, our analysis offers insight into the counterbalancing role of reflexivity, operating at both individual and collective levels of analysis, in generating the ability of entrepreneurs to overcome the constraints of imprinting. These insights are based on a thematic review of the nine studies that comprise this special issue on qualitative research. The nine studies, individually and each in their own way, offer key insights into how we might better understand the emergence of entrepreneurial opportunity.  相似文献

This essay was written for the 1984 General Motors Intercollegiate Business Understanding Program. It consists of three sections, each responding to a separate issue posed by General Motors. The opinions expressed are not those of the General Motors management.The first section attempts to document, through the use of Harvard Business Review articles, a shift in the notion of managerial responsibility from a narrowly focused role responsibility to a more widely focused moral responsibility.The second section explicates the different conceptions of Justice behind the United States and West German economic systems. It gives examples of the consequences of the different conceptions both in methods of policy formation and results.The third section deals with business ethics in international contexts. It argues that law is by itself inadequate in the regulation of business activity and must be supplemented by public discussion, which employs the traditional methods of moral reasoning.John Davis Feldmann, John Kelsay, and Hugh E. Brown III are or have been graduate students in the Department of Religious Studies at the University of Virginia. Their essay, written under the direction of James F. Childress, Edwin B. Kyle Professor of Christian Ethics, won first prize in the 1984 General Motors Intercollegiate Business Understanding Program.John D. Feldmann, currently writing a dissertation on justice and tax reform, holds a law degree from the University of Virginia. He has practiced business law, served as a Vice-President of a banking corporation, and worked for the Center for Applied Ethics at the University of Virginia's Darden Graduate School of Business Administration.John Kelsay, an ordained minister of the Presbyterian Church U.S.A., holds a Ph.D. in Religious Ethics from the University of Virginia and has been serving as an Instructor there. His dissertation dealt with ethics and society in Islam.Hugh E. Brown III, now preparing for the Episcopal ministry at Virginia Theological Seminary, holds an M.A. in Religious Ethics from the University of Virginia. Prior to entering graduate school, he had experience in business as a supervisor for an AT&T affiliate.  相似文献

The rapid growth of the United States as a whole is basically a story of the discovery and adoption of novel and improved ways of satisfying wants and needs. Previously, these wants and needs have been championed by individuals such as J.P. Morgan (finance), James B. Duke (tobacco), Andrew Carnegie (steel), Cornelius Vanderbilt (railroads), and John D. Rockefeller (oil). Each of these entrepreneurs commercialized a new idea or invention—the essence of the innovation process. Each bridged the gap between science and the marketplace by developing and commercializing a marketable innovation.Although even more of a need to reach the market as quickly as possible exists today, the majority of the innovations commercialized each year come from new or smaller organizations-often the ones with the least amount of capability and resources to accomplish the task. Existing businesses, especially larger ones, are in a much better position to bridge this gap. These companies have the existing financial resources, business skills, and usually the marketing and distribution systems to successfully commercialize a new innovation. Recognizing this capability, large companies have tried to instill an entrepreneurial spirit or an internal venturing program in an attempt to increase the amount and success of new offerings. This activity has taken on a variety of forms, one of which is the new business venture unit.What are the characteristics of a new business venture unit? Are they more successful at introducing new products than autonomous entrepreneurs? These and other questions were addressed in a research project of Fortune 1000 firms consisting of a mail questionnaire and in-depth personal interviews.The majority of these firms did not have a new business venture unit (70%). Of those firms that did, the average age of their unit was 5.3 years and the range of ages was from a few months to 20 years. In addition, the range of employees in the new business venture unit varied greatly: from one to 100. Firms in the primary product lines of chemical and medical products, computers, beauty products, and feminine products tended to have new business venture units more than did firms in other product areas. These units contained a variety of departments, including marketing (the most frequent), finance, and research and development. Through modest increases in the number of new products introduced each year, the new business venture units also significantly increased the per- centages of sales attributed to products introduced within the previous three years. A good environment for a successful new business venture unit included: encouraging new ideas; allowing mistakes and failure; making available the resources of the firm; encouraging teamwork; establishing broad per- formance goals and an appropriate reward system; and having top management strongly support the unit.  相似文献
