Generative Modeling of Human Behavior and Social Interactions Using Abductive Analysis Abstract: Abduction is an inference approach that uses data and observations to identify plausible (and preferably, best) explanations for phenomena. Applications of abduction (e.g., robotics, genetics, image understanding) have largely been devoid of human behavior. Here, we devise and execute an iterative abductive analysis process that is driven by the social sciences: behaviors and interactions among groups of human subjects. One goal is to understand intra-group cooperation and its effect on fostering collective identity. We build an online game platform; perform and analyze controlled laboratory experiments; form hypotheses; build, exercise, and evaluate network-based agent-based models; and evaluate the hypotheses in multiple abductive iterations, improving our understanding as the process unfolds. While the experimental results are of interest, the paper’s thrust is methodological, and indeed establishes the potential of iterative abductive looping for the (computational) social sciences.

Seniors’ usage of mobile social network sites

Seniors’ usage of mobile social network sites: Applying theories of innovation diffusion and uses and gratifications Myung Ja Kim, Choong-Ki Lee, Noshir S. Contractor Abstract: Seniors are substantial users of mobile devices to communicate and participate in mobile social network sites (MSNS) to interact, but there has been little theoretically based understanding of what motivates seniors’ use of MSNS for tourism. To bridge the gap, this study applied the theory of the diffusion of innovations as well as the theory of uses and gratifications to explain why seniors use MSNS. Key explanatory variables included site attachment and authentic experience. Results indicate that the effect of innovation diffusion on authentic experience was greater than on site attachment. The effect of uses and gratifications was also greater on authentic experience than on site attachment. In addition, this study examined the moderating role between purchase and non-purchase groups. The effects of uses and gratifications on site attachment and authentic experience were stronger in the purchase group than in the nonpurchase group, while on the other hand, the effects of innovation diffusion on site attachment and authentic experience were stronger in the non-purchase group than ...

The SONIC Speaker Series presents Esther Sackett Kellogg School of Management, Northwestern University Expertise Awareness in Multi-Organizational Collaboration: The Role of Goal Awareness SONIC Lab is proud to welcome Esther Sackett of the Northwestern University. Dr. Sackett will speak on Thursday, December 7th, 2017 at 2 PM in Frances Searle Building, Room 1-483. Please contact Dr. Michael Schultz with any questions.    Abstract: Multistakeholder alliances typically have dual purposes that are often in tension – 1) pooling knowledge and resources toward a collaborative goal, and 2) engaging in knowledge transfer by leveraging knowledge and resources for each individual organization’s benefit. However, research has also demonstrated that these dual purposes are also quite intertwined, as members’ sustained engagement in the alliance over time depends on the perceived value of participation in terms of meeting their own organization’s needs. Inherent in the structure of multistakeholder alliances and their dual purposes is an implicit assumption: that the distributed expertise in a multistakeholder alliance is available for the pursuit of both collaborative goals and knowledge transfer. However, each of these goals may actually require access to ...
