The history of problems dealing with competing risks is briefly outlined, beginning with Daniel Bernoulli's 1760 “Mémoir” on mortality due to smallpox and proceeding through the development of actuarial techniques and methods used in clinical research, reliability theory, population dynamics, and other areas of application. A probabilistic formulation of the theory of competing risks is then presented which appears applicable to all these areas. Within the framework of this theory, some fundamental problems are stated and discussed, such as questions of identifiability, choices of estimation procedures, or techniques for testing hypotheses. 相似文献

This study tested the proposition that relationships among the various types of work-related commitment and job performance are affected by both the form of commitment and the facet of performance under consideration. Results provided some support for this view. As hypothesized, job involvement was related only to performance tied to intrinsically rewarding elements of work, and career commitment was positively related to overall performance effectiveness. Unexpectedly, however, organizational commitment (both affective and continuance) was unrelated to job performance. The discussion is centered on practical implications of these findings and on directions for future research. © 1998 John Wiley & Sons, Ltd. 相似文献
