This study explores the resource dependency and relational exchange theories of understanding firms’ participation in e-procurement, and seeks to determine the degree to which the resource dependency theory variables — supply importance, supply complexity, supply market dynamism, and availability of alternatives — affect information exchange and operational linkages, the relational exchange the...

A species’ range limits may shift in space either because of changes in ecological factors (e.g. climate, the abundances of interacting species) or because the traits which influence range limits (e.g. dispersal, niche characteristics) evolve by natural selection. In Geographical Ecology, Robert MacArthur (1972) provided a synthesis of the evolutionary factors that may drive range dynamics. In ...

This chapter identifies the issues that might create orthogonal complexities for process dynamism, and decouples the components implementing them in a “domain specific” way. Authors believe that traditional process management techniques for modeling and executing the processes still fall short to improve the dynamism of an enterprise. Some of the reasons are: using too “generic” techniques and ...

Web services play a key role in bioinformatics enabling the integration of database access and analysis of algorithms. However, Web service repositories do not usually publish information on the changes made to their registered Web services. Dynamism is directly related to the changes in the repositories (services registered or unregistered) and at service level (annotation changes). Thus, user...

Mounting evidence suggests that economic dynamism and entrepreneurial activity are declining in the United States. Over the past thirty years, the annual number of new business startups and the pace of job reallocation have declined significantly. A variety of causes for these trends have been suggested, including an increasing ability of firms to respond to idiosyncratic shocks, technology ind...

This study uses structural equation models to describe how objective neighborhood, perceived neighborhood, and environmental support predict mental health; 792 adolescents responded to highly structured interviews. The effect of objective environment on mental health was mediated through its influence on perceived neighborhood. Environmental support mitigated negative perceptions of environment...

Applying a configuration-theoretic approach to study multiple channels, the authors hypothesize that multiplechannel systems make their greatest contributions to firm performance when their structures are properly aligned with their firms’ business-level strategies and with environmental conditions. A conceptual model incorporating these variables is supported in an empirical study of responses...
