Dec

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 ...

SONIC Lab is proud to welcome Ingmar Weber who will present a talk on Wednesday, November 16th, 2016 at 2:00 PM in Frances Searle Building, Room 1-459. Please contact SONIC Lab Manager Katya Bitkin with any questions or comments. Demographics in Social Networks: Usage Differences, Content Spread, and Homophily Abstract   How do demographic attributes affect network structure and content spread? In this talk, I’ll present attempts to address this question using a demographically annotated data set for 350K Twitter users in New York. For each user, their gender, age and race has been inferred from their profile picture using Face++. I’ll start by  showing that population-level differences in hashtag usage are intuitive, such as African Americans being more likely to use #blacklivesmatter, women more likely to use #makeup, and young people more likely to use #growingupwithsiblings. Taking ideas previously studied in the context of web search, we then look at  which demographic groups are generally first – or last – to use new hashtags. Here we find that, e.g., new music-related hashtags tend to originate from African American users, whereas new baseball hashtags come from white men. Looking at the topic ...

Tertius Gaudens, Tertius Iungens, and the Temporality of Structural Holes Abstract Organizational network research has demonstrated that multiple benefits accrue to people occupying brokerage positions. However, the extant literature offers scant evidence of the process postulated to drive such benefits –information brokerage– and therefore leaves unaddressed the question of brokers broker. We address this gap by examining the information-brokerage interactions in which actors engage. We argue that the information-brokerage strategies of brokers differ in three critical ways from those of actors embedded in denser network positions. First, brokers more often broker information via short-term interactions with colleagues outside their network of long-term relationships, a process we label “unembedded brokerage.” Second, when they engage in unembedded brokerage, brokers are more likely than are actors in dense ...

Frames and Fields on Twitter Associate Professor School of Sociology Centre for Social Research & MethodsANU College of Arts and Social Sciences Abstract We characterize an online activist field as a social arena in which participants vie for the definition of the most urgent cause or risk issue. We ask the question: to what extent is it conceptually and empirical valid to regard protest activity on Twitter, such as the Occupy Wall Street movement, as an online activist field? Network analysis is used to examine two core aspects of field theory: the behavior of incumbents vs new entrants in response ...

Associate Professor, Organizational Behavior, Weatherhead School of Management, Case Western University The New Foundations: Emergence, Constructionism and the New Reductionism Abstract The science of studying emergence is not well understood among organizational scholars.  Scholars often transfer assumptions from variance analysis to this particular application of process analysis.  Further, its components parts—emerging, emergent outcomes and their properties—are often confounded leading to muddled thinking.  In this paper, I distinguish among these components.  Specifically, I discuss the features of complex systems drawing out distinctions between complex vs complicated non-linear systems, constituting vs causing, aggregation, levels, and holism.  I draw out the implications of this research approach, emphasizing the paradigm shift required to apply it from ...

SONIC Lab is proud to welcome Brian Keegan, who will present a talk on Friday, November 13th, 2015 at 1:30 PM in the SONIC Lab in the Frances Searle Building 1-459. All are welcome to attend. Title Collaboration in Bursty Information Systems: Wikipedia’s Coverage of Breaking News Events Abstract Bursts are characterized by a sudden onset, significant change in intensity, and temporary duration of collective social behavior. As “software eats the world” and makes critical economic and social infrastructures more interconnected, managing ever more interoperable information systems in the face of bursts will take on heightened importance. Wikipedia’s coverage of current events is a compelling context to understand how open collaborations coordinate complex, time-sensitive, and knowledge-intensive work in the absence of central authority, stable membership, clear roles, or reliable information. Using 1.1 million revisions made to 3,233 articles Wikipedia articles about current events between 2001 and 2011, I employ social network analysis methods to test whether the structures of high-tempo collaborations on Wikipedia articles are (a) similarly structured over time, (b) exhibit features of organizational regeneration, and (c) have similar collaboration dynamics over time. The mediation of bursty behaviors through information systems capturing detailed records enables researchers to develop richer models of the antecedents, processes, and ...

Sep

On September 9th, 2015, Ludo Waltman visited Northwestern University’s SONIC Lab to give a talk on Large-scale analysis of bilbliometric networks: Tools, techniques, and applications. Ludo’s full abstract, as well as the presentation, can be seen below. Large-scale analysis of bibliometric networks: Tools, techniques, and applications Abstract The analysis of bibliometric networks has the potential to offer deep insights into the structure and dynamics of science. I will provide an overview of research into bibliometric network analysis at the Centre for Science and Technology Studies (CWTS) of Leiden University. Two popular software tools for the analysis and visualization of bibliometric networks have been created at CWTS. These tools, VOSviewer (www.vosviewer.com) and CitNetExplorer (www.citnetexplorer.nl), will be demonstrated and the underlying network analysis techniques will be discussed. A number of large-scale applications of bibliometric network analysis will be presented. One application investigates the degree to which network science is evolving to become a single unified research field. Other applications are concerned with research planning and research evaluation. In these applications, bibliometric network analysis is used to identify the key research strengths of a university, to study the interdisciplinary nature of modern science, and to ...
