Interplay Between Individual And Group Structure In NetworksReichardt, Joerg; Alamino, Roberto; Saad, DavidAnalyzing Network DataBayesian Methods, Block Model Analysis, Sports Participation, Community Detection, Analytical Methods, EquilibriumFRI.PM1Network structure is the result of a complex interplay between latent and observed characteristics at the level of both individual nodes as well as groups ofnodes. However, when inferring latent group structure using stochastic a‐posteriori block models, the expansiveness and attractiveness of individual nodeshave generally been excluded from such models. We present a computationally efficient Bayesian framework for inferring stochastic block structure innetworks that includes the estimation of node specific expansiveness and attractiveness parameters as well as block specific reciprocity. This corresponds to a‐posteriori block modeling in a dyadic exponential random graph model (ERGM), also known as p1‐model. We show that neglecting individual expansivenessand attractiveness when inferring block structure may lead to wrong assignments of nodes into classes and hence wrong conclusions about the block structurein the graph. Further, we show that inferring latent block structure and block specific reciprocities may allow for an accurate representation of the triad censusin networks, while still using a computationally simple dyadic model. Our approach applies to undirected, directed as well as bi‐partite networks.Interprofessional Relationships Among Biomedical And Complementary/alternative PractitionersWellman, Beverly; Kelner, MerrijoyQualitative and Mixed Method Network studiesMixed Methods, Healthcare Networks, Collaboration Network, Interprofessional CollaborationTHURS.AM2Working in collaborative teams requires a blurring of professional boundaries, new role definitions, and sharing of professional knowledge, skills and power.One instance of interprofessional collaboration that is currently receiving attention is integrative health care, a combination of biomedical care andcomplementary and alternative medicine. This study traces the perspectives and experiences of health care practitioners working at two different integrativehealth care centres as they strive to adapt their professional identities and practices to working in collaborative interprofessional teams. We asked about theirmotivations for working in a team setting, whether there are formal mechanisms to enhance collaboration, the nature of their everyday interactions with otherpractitioners, and whether they feel that they operate as part of a team or on their own. We analyze how professionals adapt to an environment that iscounter to the unique ways they have been socialized, and to observe how they relate to each other and share patient information as team members underone physical and organizational roof. We interviewed all the practitioners at each of the two centres. We are continuing to attend staff meetings as well assitting in the waiting rooms observing. Initial findings and reviews of the literature suggest that collaboration is more than co‐location. Without formalstructures and strong leadership guiding the team towards collaboration and communication, achieving it is unrealistic.
