Data are presented to support the argument that motivation to manage is a major cause of managerial effectiveness, that it declined sharply in the college population during the activism of the 1960s and early 1970s, and that it is now severely lacking in the United States relative to many other countries. Thus America's competitiveness problems appear to be largely motivational in nature. Possible solutions are discussed, including recruiting and selecting for managerial motivation, increasing motivation to manage using training and development techniques, and changing organizational designs (telescoping the scalar chain, moving managerial tasks into non-managerial positions, resorting to professional forms, and expanding venture structures). © 1995 by John Wiley & Sons, Inc.  相似文献

Ordering univariate distributions by entropy and variance   总被引:1,自引:0,他引:1  
This paper examines the role of variance and entropy in ordering distributions and random prospects. There is no universal relation between entropy and variance orderings of distributions. But we place their relationship in the context of a stronger ordering relation known as dispersion ordering. Further, some conditions are identified under which variance and entropy order similarly when continuous variables are transformed. We also analyze parametric changes which do not disturb the agreement between these rankings. The results are conveniently tabulated in terms of distribution parameters.  相似文献

Cooperation is a necessary condition, along with competition, for the creation of wealth, innovation and knowledge. We briefly re-visit and critique certain neo-classical arguments in regards to pure competition and profit maximization that continue to be carried forward by current neo-liberal thought. We also attempt to illustrate the unbalanced and damaging outcomes of neo-liberal logic across the lens of enactment; as well as across our own discernment of holographic analogies to the individualism–collectivism dyad that exist within our complex environments. Within the spirit of evolutionary economics and complexity theory, early and more recent theoretical and empirical underpinnings for cooperation are presented, with the argument that it, combined with competition, leads to more well-balanced wealth creation—be it regional, national or global in character. Finally, we review competitive vs cooperative economic approaches across the lens of emergent complex systems. We then present two possible ‘future’ scenarios: one extreme outcome occurring as a result of truncating or de-balancing the individual vs collective dyad and its holographic analogies; while another outcome attempts to integrate a more inherent balance within these same dyads.  相似文献

Information-theoretic methodologies are increasingly being used in various disciplines. Frequently an information measure is adapted for a problem, yet the perspective of information as the unifying notion is overlooked. We set forth this perspective through presenting information-theoretic methodologies for a set of problems in probability and statistics. Our focal measures are Shannon entropy and Kullback–Leibler information. The background topics for these measures include notions of uncertainty and information, their axiomatic foundation, interpretations, properties, and generalizations. Topics with broad methodological applications include discrepancy between distributions, derivation of probability models, dependence between variables, and Bayesian analysis. More specific methodological topics include model selection, limiting distributions, optimal prior distribution and design of experiment, modeling duration variables, order statistics, data disclosure, and relative importance of predictors. Illustrations range from very basic to highly technical ones that draw attention to subtle points.  相似文献

This study aims to shed light on the debate concerning the choice between discrete-time and continuous-time hazard models in making bankruptcy or any binary prediction using interval censored data. Building on the theoretical suggestions from various disciplines, we empirically compare widely used discrete-time hazard models (with logit and clog-log links) and the continuous-time Cox Proportional Hazards (CPH) model in predicting bankruptcy and financial distress of the United States Small and Medium-sized Enterprises (SMEs). Consistent with the theoretical arguments, we report that discrete-time hazard models are superior to the continuous-time CPH model in making binary predictions using interval censored data. Moreover, hazard models developed using a failure definition based jointly on bankruptcy laws and firms’ financial health exhibit superior goodness of fit and classification measures, in comparison to models that employ a failure definition based either on bankruptcy laws or firms’ financial health alone.  相似文献

Oil jump risk     
The risk premium associated with large upside jumps in oil market is a significant driver of the cross-section of stock returns from 1986 to 2014. In contrast to previous research, variance risk is priced only when we do not control for jumps. Upward jumps are priced in tight supply-demand conditions but not in more abundant supply periods. There is some evidence that downward jumps are priced in abundant supply conditions but not in tight conditions. Innovations in risk neutral jumps have predictive power for important economic indicators, including notably consumption growth. This helps explain the pricing of jump risks.  相似文献

Since 1979, the People's Republic of China (PRC) has made tremendous economic progress. As a result, China and its management practices have received increasing research attention. Human resource management practices in China have been extensively explored elsewhere. Unfortunately, little research has dealt with the concept of hierarchical role motivation theory; its main construct, motivation to manage; and its potential implications for strategic human resource practices in the PRC. The study reported here is an attempt to fill this void.  相似文献

Chinese mainland business expatriates assigned to Hong Kong were surveyed assessing their socio-cultural and psychological adjustment. The investigation explored the association of a variety of personal characteristics with adjustment to work and life in the territory. The main results of the study showed that expatriates from the neighbouring Guangdong Province, male expatriates, younger expatriates and expatriates who were accompanied by their spouses were better adjusted in Hong Kong than others. On the other hand, expatriates recruited directly from universities were less well adjusted than those hired from other sources. Implications of these findings are drawn and future avenues for improving and extending this kind of exploratory research are discussed.  相似文献

The role of the so-called surplus processes in the assessment of probability of survival of a company is well-known in risk theory and applications thereof. However, the insurance models used in this regard ignore the fact that, in many situations, no relevant information is available for the assessment of survival after the company goes out of business. In this paper, we revisit the classical risk model in order to remedy this situation. Having stopped the deficit process, which is negative of the surplus process, at the time of ruin, under two different sampling schemes, we obtain inference procedure for ruin probabilities. As by products of our methodology, we also obtain procedures to assess the reliability of systems whose survival depends on a cumulative damage process, which is equivalent to the aggregate claim size process of the classical risk model.  相似文献
