Abstract: Although Resource Dependence Theory has proven useful in understanding relations between organizations, the theory has fallen into disuse. Since it was first put forward using ideas from an early formulation of Power-Dependence Theory, Resource Dependence Theory has not remained in contact with developments of that theory. Nor has it been informed by developments of competing theories of exchange networks in sociology. Had it done so, undoubtedly Resource Dependence Theory would have grown and taken up new and increasingly complex problems. In fact, Resource Dependence Theory has remained largely static, while, in sociology, Network Exchange Theory has experienced steady growth through an interaction of theory development and experimental testing. The recent extension of Network Exchange Theory to flow networks – networks where resources flow through multiple nodes – has opened the way for precise interorganizational applications. In this paper, I extend that theory to flow networks with multiple commodities, an application which according to Salancik (1972) is vital for any theory seeking to predict and explain exchanges in interorganizational networks. Experimental tests for my extension are suggested.

Abstract: An exact mathematical solution for the low Reynolds number motion induced by a rod in the form of a prolate spheroid sweeping a symmetric double cone is developed, and the influence of the ensuing fluid motion upon passive particles is studied. The advected particles are observed to admit slow orbits around the rotating rods and a fast epicyclic motion roughly commensurate with the rod rotation rate. The epicycle amplitudes, vertical fluctuations, arclengths and angle traveled per rotation are mapped as functions of their initial coordinates and rod geometry. These trajectories exhibit a rich spatial structure with greatly varying trajectory properties. The Eulerian and Lagrangian flow properties of the fluid flow are also studied and shown to exhibit complex structures in both space and time. We establish the origin of these complexities via an auxiliary flow in a rotating frame, which provides a generator that defines the epicycles. Finally, an additional spin around the major spheroidal axis is included in the exact hydrodynamic solution resulting in enhanced vertical spatial fluctuation as compared to the spinless counterpart. The present study is of direct use to nano-scale,actuated fluidics.

Abstract: The standard gravity model implicitly postulates dyadic independence, which claims that trade flows of any pair of countries can be reduced to individual and dyadic characteristics. This ignores, however, the fact that countries are embedded in trade network structure and the fact that the network structure can enhance or inhibit bilateral trade. Thus, we hypothesize the embeddedness effect on bilateral trade, occurring when two countries share the same third parties as trade partners. Put another way, sharing the same third parties, we hypothesize, generates a structural force encouraging trade between the two countries involved in trade. We find consistent empirical evidence supporting the hypothesis: as a pair of countries trade more with the same third parties, the bilateral trade between them increases as well, even after taking into account the standard gravity variables, such as economic size and distance.

Abstract: An experiment was conducted to examine the effectiveness of a highly proactive approach to crisis communication labeled “stealing thunder.” Journalists and journalism students were asked to read one of two fictitious crisis scenarios: one in which the organization’s P.R. practitioner stole thunder (broke the news about the crisis) by contacting the journalist, and one in which the journalist learned about the crisis from another party. When the organization stole thunder, journalists rated the practitioner as more credible, but also indicated greater interest in the story. No differences were found across the two conditions in terms of perceptions of crisis severity or framing of news leads written by the journalists. Implications for crisis communication and the ongoing journalist-practitioner relationship are discussed.
