conclusion The Information Age has revolutionized the workplace. While it is possible to purchase or copy machines and technology, their very interchangeability means they fail to cre-ate a sustained competitive advantage for an organization (Barney, 1991). The research directions this paper offers are intended to develop firm knowledge that allows creation of inimitable human resources. Importantly, in the rush to embrace new information technologies, organizations must remember the fundamental principle that workers will invest in firm goals in the presence of shared values and a commitment by the firm to make their well-being a priority. We urge continued attention to fulfillment of the psy-chological contract, and to the "people issues" that frequently seem less critical than issues of hardware or technology.  相似文献

This paper elaborates on some issues discussed by Moskowitz, who presented evidence that linear multiple regression models, estimated from decisions made by individuals, often outperform the individuals themselves. In discussing his results, Moskowitz (1) suggested that inconsistency in information utilization by individuals may account for the relative superiority of regression models, and (2) expressed concern over the robustness of linear regression models to changes in (a) information environments, (b) weighting parameters, and (c) functional form of the model. This paper discusses reasons (in addition to inconsistency) for the relative superiority of model over man, and it summarizes recent research in psychology concerning the robustness of linear regression models (and linear models in general). This paper is supportive, rather than critical, of Moskowitz's research.  相似文献

A number of methods of obtaining the distribution of the optimum of the ‘wait and see’ stochastic programming model have been proposed, but computational experience for these is currently limited to the solution of small problems. The purpose of this paper is to discuss the role of the ‘wait and see’ model in planning, and to propose a method of analysis based on the minimax and maximax decision criteria. The approach requires the solution of a special class of non-linear programming problems. Computational results to date suggest that it will be possible to analyse practically sized problems in this way.  相似文献

The theory and properties of trend-free (TF) and nearly trend-free (NTF) block designs are wel1 developed. Applications have been hampered because a methodology for design construction has not been available.

This article begins with a short review of concepts and properties of TF and NTF block designs. The major contribution is provision of an algorithm for the construction of linear and nearly linear TF block designs. The algorithm is incorporated in a computer program in FORTRAN 77 provided in an appendix for the IBM PC or compatible microcomputer, a program adaptable also to other computers. Three sets of block designs generated by the program are given as examples.

A numerical example of analysis of a linear trend-free balanced incomplete block design is provided.  相似文献

Abstract

Objective: The object of this exploratory evaluation was to evaluate the “Bringing in the Bystander” sexual and intimate partner violence prevention program with a new sample of intercollegiate athletes. Participants and Methods: Fifty-three male and female athletes participated in the program (experimental group), and 86 were in the control group. All completed pretest, posttest, and 2-month follow-up surveys, including assessment of rape myth acceptance, intent to engage in bystander behaviors, bystander confidence, and bystander behaviors. Results: The program worked overall and for both women and men, improved bystander confidence and intent to engage in bystander behaviors, and did not create significant backlash effects (ie, worsening of attitudes as a result of program). Conclusions: The program fits with the intent of the National Collegiate Athletic Association CHAMPS/Life Skills program regarding its focus on the overall development of student-athletes and demonstrates the promising bystander approach compatible with the 2007 American College Health Association toolkit, Shifting the Paradigm: Primary Prevention of Sexual Violence.  相似文献

A method for combining forecasts may or may not account for dependence and differing precision among forecasts. In this article we test a variety of such methods in the context of combining forecasts of GNP from four major econometric models. The methods include one in which forecasting errors are jointly normally distributed and several variants of this model as well as some simpler procedures and a Bayesian approach with a prior distribution based on exchangeability of forecasters. The results indicate that a simple average, the normal model with an independence assumption, and the Bayesian model perform better than the other approaches that are studied here.  相似文献

In this essay, we argue that, following their perception of practices in the natural sciences the social sciences have reified methodology, making it the chief imperative of social investigation and using it to ground their knowledge claims. We find this to be the case even in the work of social scientists who try to overcome or reject the dominant positivist paradigm. We argue that this obsession with method has led the social sciences to abandon thinking-beyond-the-given in favor of small, specialized studies whose justification is no longer substantive but methodology driven. After a review of the history of the role of method in traditional philosophies of science, the essay turns to the work of recent critics of social science who have become increasingly dissatisfied with modeling the social sciences after the natural ones. We distinguish between a hermeneutic and phenomenological critique of positivism, both of which, we argue, end up reproducing the scientism they reject. We identify this problem in our careful readings of some of the most influential critics of Popperian scientific philosophy. In the final section, we distinguish between contemporary social science, situated in what we term the epistemological paradigm, and our own critical science, stemming from an alternate, ontohistorical tradition in the history of ideas. Here, we begin to lay out what a critical, nonmethodology-driven, reflective and historical science might look like.  相似文献

In a series of major papers culminating in A Theory of Justice, John Rawls constructs an alternative to utilitarianism by developing a social contract theory of moral and political philosophy. Unfortunately, Rawls formulates the two basic principles upon which the theory rests in such a way as to restrict (unduly) the contract theory's applicability (see Section I). In this paper we present a more general discussion of the theory of justice that avoids the problems of Rawls' formulation and yet retains the important idea of justice as fairness and the contractarian approach (Section II). Later it is argued that this more general theory constitutes a bridge between the pure utilitarian theories and the social contract doctrines (Sections V and VI). The theory's advantages are demonstrated by applying it to a problem discussed by Rawls, intergenerational equity, and comparing the two solutions (Section III). Further comparisons are made and inferences drawn in the concluding three sections.Without implicating them, we would like to thank James M. Buchanan and David Lyons for comments on an earlier draft of this paper.
