Strategic management research has been characterized as placing less emphasis on construct measurement than other management subfields. In this work, we document the state of the art of measurement in strategic management research, and discuss the implications for interpreting the results of research in this field. To assess the breadth of measurement issues in the discipline, we conducted a content analysis of empirical strategic management articles published in leading journals in the period of 1998–2000. We found that few studies discuss reliability and validity issues, and empirical research in the field commonly relies on single‐indicator measures. Additionally, studies rarely address the problems of attenuation due to measurement error. We close with a discussion of the implications for future research and for interpreting prior work in strategic management. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

This paper develops twenty hypotheses concerning the relationships among selected individual differences variables (locus of control, delay of gratification, gender, and race) and five different ethical beliefs. The results of a study of collegians provide support for seventeen out of twenty research hypotheses. As predicted, locus of control, delay of gratification, and race are related to ethical beliefs. Also as predicted, gender is not related to ethical beliefs. Michael K. McCuddy, Professor of Human Resource Management at Valparaiso University, has conducted research on a variety of organizational topics. His work has been published in the Academy of Management Journal, Journal of Applied Psychology, Journal of Organizational Behavior Management, The Health Care Supervisor, and Management Accounting. His current interests involve academic ethics and subsequent career behavior, organizational morality and organizational success, and ethics in the management accounting profession. Barbara L. Peery, Adjunct Professor of Management at Virginia Commonwealth University, teaches courses in Entrepreneurship and Human Resources Management. Her scholarly work has been published in the Journal of Small Business Management and the Journal of Private Enterprise. Her current research interests focus on the antecedents and consequences of academic ethics. She has co-directed or coordinated several consulting projects for agencies in the Commonwealth of Virginia, and has taught in Russia.  相似文献

The life span of a product is a key component in assessing its environmental impact. Until very recently, however, product durability was far from prominent in the environmental debate. This has begun to change due to mounting concern about waste, the prospect of producer ‘take back’ schemes and the importance of quality in highly competitive international markets. This has led to product durability emerging on the business and environment agenda. This paper explores the significance of product life spans and identifies currently available data on the life-span of consumer durables. It defines product life and argues that, from an environmental perspective, optimum product life, rather than maximum product life should be the goal. It suggests that potential advantages to businesses of manufacturing and retailing products with longer life spans include improved environmental foresight (i.e. a greater responsiveness to new social trends, changes in consumer behaviour and tighter government regulations), an enhanced reputation for quality, greater potential market share and increased customer loyalty. Addressing claims that manufacturers deliberately make products with the intention that they should have life spans below the known technical potential, the paper identifies some of the influences upon manufacturers which encourage shorter product life spans. Finally, some means by which longer life products might be encouraged are proposed.  相似文献

This paper concerns the behavior of gold and silver prices on a daily, weekly and monthly time span during January 1970 to December 1989. The methodology consists of extracting the predictive power of time series of changes in past prices for obtaining optimal forecasts for next-period changes in prices. Optimizations are made in the context of information theory via minimizing the degree of diversity between the actual and predicted changes in prices. This methodology has merit in that it does not rest on, generally speaking, unacceptable assumptions regarding the shape of the distribution, stationarity of variance or its existence. The behavior of gold and silver prices are studied during peak to trough and trough to peak of the business cycles over 1970–1989. It is generally shown that information contained in past prices of gold and silver does not allow one to predict next-period changes in prices in the short run. However, longer-term predictions are possible. This study further reveals that as the length of the time interval expands, gold prices exhibit a higher degree of dependency on past prices than silver.  相似文献
