Global health networks, webs of individuals and organizations with a shared concern for a particular condition, have proliferated over the past quarter century. They differ in their effectiveness, a factor that may help explain why resource allocations vary across health conditions and do not correspond closely with disease burden. Drawing on findings from recently concluded studies of eight gl...

In this paper we obtain several tight bounds on different types of alliance numbers of a graph, namely (global) defensive alliance number, global offensive alliance number and global dual alliance number. In particular, we investigate the relationship between the alliance numbers of a graph and its algebraic connectivity, its spectral radius, and its Laplacian spectral radius.

In today’s environment of global competition/cooperation, distributed organizations often have to federate into alliances in order to improve their ability to accomplish their customers’requests. Such alliances may establish very tight relationships between their members, as, for example, in the “supply chain” models. We are interested here in another kind of “businessto-business” alliances, de...

Managing organizational knowledge in alliances implies establishing the best possible strategic design to create, acquire, maintain, transfer, and apply organizational knowledge developed between the partners (or acquired from partners) in order to achieve competitive goals. In this paper, the role of knowledge management strategy (KMS) in strategic alliances is analyzed in a technology-intensi...

BACKGROUND Hospital purchasing alliances are voluntary consortia of hospitals that aggregate their contractual purchases of supplies from manufacturers. Purchasing groups thus represent pooling alliances rather than trading alliances (e.g., joint ventures). Pooling alliances have been discussed in the health care management literature for years but have never received much empirical investigati...
