Abstract : The genesis and evolution of NGO communities
One of the most pronounced changes in the last decade has been the significant increase in the number and influence of non-profit nongovernmental organizations (NGOs) and their networks. While NGO networks have been the subject of several studies in the last decade, these studies have tended to focus on the characteristics and evolution of already well established organizational population networks. While such research has contributed to our understanding of processes of network evolution, it does not sufficiently account for the complexity inherent in the genesis of NGO populations. The purpose of this research is to examine the genesis of NGO networks among newly established populations. These population networks emerge within the context of a community of NGO populations. As such, the study is an empirical examination of the emergence of four populations of NGOs, HIV/AIDS, infectious diseases, third world development, and sustainable development NGOs, and their networks. Examining these NGO populations from 1950 to 2007, this research investigates the influence of functional identity niches, geographic regions, organizational types, and network effects on the genesis and evolution of these networks.

Abstract : The coevolution of an INGO collaboration network with external relations
While interorganizational network theorizing suggests that multiplex relationships with external populations should influence the pattern of collaboration within populations over time, empirical research has typically only examined the coevolution of collaborative relationships with one other relation. This research examines the coevolution of international nongovernmental organization (INGO) collaborative patterns (N = 264), accounting for reciprocity, popularity of alter, transitive triads, organization type, and geographic region, with five external relations: founding, funding, intergovernmental organizations (IGO) consultative status, IGO collaboration, and membership. Drawing data from the 1993-2007 Yearbook of International Organizations, this paper utilizes SIENA actor-oriented modeling to examine the influence of each of these relations over 8 waves of data. Each of these relations is transformed into co-membership matrices, so that common external relationships are predictive of collaboration. In addition, each of these parameter’s interaction with organization type, or the type of social issue the organization addresses, are modeled. Results of this research will contribute to a growing body of literature on the co-evolution of interorganizational relationships and offer significant implications for the NGO sector.
