Untangling the effects of overexploration and overexploitation on organizational performance: The moderating role of environmental dynamism

Because a firm's optimal knowledge search behavior is determined by unique firm and industry conditions, organizational performance should be contingent oil the degree to which a firm's actual level of knowledge search deviates from the optimal level. It is thus hypothesized that deviation from the optimal search, in the form of either overexploitation or overexploration, is detrimental to organizational performance. Furthermore, the negative effect of search deviation oil organizational performance varies with environmental dynamism: that is, overexploitation is expected to become more harmful. whereas overexploration becomes less so with all increase in environmental dynamism. The empirical analyses yield results consistent with these arguments. Implications for research and practice are correspondingly discussed

MENTAL HEALTH CARE FOR OLDER PERSONS: NETWORKING AS A RESPONSE TO ORGANIZATIONAL CHALLENGES -super-1

We use case study methodology to examine the degree of cooperation and coordination among organizations providing mental health care to older persons. Mail surveys and in-depth interviews were employed to gather data from human service organizations in one relatively rural county of Upstate New York. We find that organizations that are older and provide larger numbers of services tend to have a higher degree of integration with other organizations. There is little evidence of formal coordination of services. Informal cooperation, at least on an ad hoc basis, is common, though. Older persons with chronic mental health problems are relatively well served by the system. Older persons whose mental health problems are associated with the aging process are not well served by the system. The growth of mental health managed care has increased competition among many organizations, further fragmenting a weakly integrated system. Copyright 2000 by The Policy Studies Organization.

New Size Measurements in Population Ecology

In organizational ecology, the analysis of the impact of competition between populations on vital ratios is relatively underdeveloped. This paper addresses this issue by developing new competition measurements that focus on the importance of organizational size. The application of these measurements in the case of competition between organizational subforms in a population, and their impact on mortality rates, demonstrate their usefulness for modelling competition. Specifically, the results show how levels of competition between firms in a population can be more clearly analysed when the rival population mass or concentration indices are used.
