A Structural And Linguistic Approach To <strong>Social</strong> Roles: An Examination Of Im/politeness And Influence In Online Health Management CommunitiesMastarone, GinniferWords and <strong>Network</strong>s ‐ Roles, Health, Methods<strong>Social</strong> Influence, <strong>Social</strong> Media, Health, Politeness TheoryFRI.PM1<strong>Social</strong> networking sites such as Dailystrength.org represent online communities where patients and caregivers engage in health management. Within thesecommunities, social influence serves as a mechanism <strong>for</strong> carving the identity, in<strong>for</strong>mation practices and norms of the community. Structural theories ofinfluence rest on arguments regarding the relationship between social structure and in<strong>for</strong>mation flows. Particularly, the role of Influentials within diffusionnetworks has come under scrutiny in the literature (e.g. Watts & Dobbs, 2007). However, the sole analysis of structural positions does not take into accountlinguistic processes that are used to decrease social distance, manage identity and define hierarchal roles within online communities. Furthermore, theanalysis of im/politeness strategies outside of the context of the social network does not accurately represent the relational attributes of individual and groupidentity management. There<strong>for</strong>e, a community‐based model of im/politeness must be developed to reflect the relational discursive patterns between actors.In this paper, I theorize that an actor's politeness tactics coupled with their structural positioning provides a more holistic explanation of why particular actorsassume certain social roles (e.g. brokers, marginals) within the health management network. I examine message board and blog posts hosted onDailystrength.org <strong>for</strong> politeness strategies as well as identify social roles through social network analysis. I expect that this research will contribute to ourunderstanding of community <strong>for</strong>mation and leadership within online health communities.A Study On The Synchronization Of World Stock Markets Via <strong>Network</strong> AnalysisChoi, Seungil<strong>Network</strong>s and EconomicsMinimum Spanning Trees, Syncronization, Stock MarketsFRI.PM2In the progress of the recent global financial crisis, we have seen an increased synchronization of world stock markets. With the correlation data among majorstock indices, we construct the minimum spanning trees over time and analyze the dynamics of these minimum spanning trees. First, we ask when anynoticeable increases in returns synchronization of world stock markets occur. Second, we ask if there were any noticeable changes in network indicatorspreceding a financial crisis. Third, can we explain any effects of the G20 on the synchronization of world stock markets via network analysis? Different fromprevious studies on the synchronization of stock markets with GARCH models, this research applies network analysis to explain the characteristics of globalstock market synchronization.
