The SONIC Speaker Series presents Prasad Balkundi Organization and Human Resources, University of Buffalo The Negative Side of the Social Ledger: A Meta-Analysis SONIC Lab is proud to welcome Prasad Balkundi of the University of Buffalo. Dr. Balkundi will speak on Wednesday, April 18th, 2017 at 10 AM in Frances Searle Building, Room 1-483. Please contact Dr. Michael Schultz with any questions.   Abstract: Despite a resurgence of research on negative ties in social networks, a comprehensive understanding of negative and positive has yet to be provided. Incorporating evidence from prior 163 independent samples we examine whether the initiation of positive and negative relationships (i.e., out-degree) or the reception of positive and negative relationships (i.e., in-degree) is more impactful to the focal employee’s effectiveness. Furthermore, to address the negative asymmetry hypothesis in social networks, we compare the relative importance of positive versus negative work relationships while holding the directionality constant. This meta-analytic review makes five contributions to theory on negative and positive social networks by (a) demonstrating the undermining impact of negative ties on performance and job attitudes; (b) providing information on the negative ...

The SONIC Speaker Series presents Gianluca Carnabuci Organizational Behavior, ESMT Berlin Good For One But Bad For Most? How Intra-Organizational Networks Impact Innovative Performance At The Inventor And Firm Level SONIC Lab is proud to welcome Gianluca Carnabuci of ESMT Berlin. Dr. Carnabuci will speak on Wednesday, April 26th, 2017 at 10 AM in Frances Searle Building, Room 1-483. Please contact Dr. Michael Schultz with any questions.   Abstract: Extant organizational research suggests that R&D scientists tend to be more productive (i.e., they generate more impactful innovations) when they occupy a central position within their organization’s intra-organizational collaboration network. Does this imply that an organization’s overall innovative performance would increase if the organization encouraged its R&D scientists to pursue more central network positions? We address this question using a multi-level panel dataset describing the evolving intra-organizational networks of 140 semiconductor firms, as well as the individual network position of each of their R&D scientists. We proceed in three steps. First, we confirm that network centrality does enhance scientists’ innovative performance within our empirical sample, even after controlling for unobserved individual- and organizational-level differences. Second, we simulate how the overall intra-organizational network of ...

Sadat Shami of IBM. Dr. Shami will speak on Monday, February 26th, 2017 at 10 AM in Frances Searle Building, Room 1-483. Please contact Dr. Michael Schultz with any questions.   Abstract: The increased adoption of social media in the enterprise provides an opportunity for organizations to receive real-time feedback from employees on organizational issues. Enterprise social media provides a platform for employees to express their thoughts and opinions on organizational programs, policies, and strategies through unstructured text in status updates, blogs, online community forums etc. Such textual data can be mined to generate insights about the employee experience. Research has shown that organizations that take into consideration employee feedback in organizational decision-making are more productive, and have employees that are more engaged with the organization. In this talk, he will first describe the design and use of Social Pulse – a tool to make ...

The SONIC Speaker Series presents Johan Ugander Management Science & Engineering Stanford University Ruffled Feathers: Trait inference beyond homophily SONIC Lab is proud to welcome Johan Ugander of Stanford University. Dr. Ugander will speak on Tuesday, February 6th, 2017 at 10 AM in Frances Searle Building, Room 1-483. Please contact Dr. Michael Schultz with any questions.   Abstract: The observation that individuals tend to be friends with people who are similar to themselves, commonly known as homophily, is a prominent and well-studied feature of social networks. While homophily describes a bias in attribute preferences for similar others, it gives limited attention to variability. In this work, we observe that attribute preferences can exhibit variation beyond what can be explained by models of homophily. We call this excess variation monophily to describe the presence of individuals with extreme preferences for a particular attribute possibly unrelated to their own attribute. We observe that monophily can induce a similarity among friends-of-friends on a network without requiring any similarity among friends. In order to independently simulate homophily and monophily in synthetic networks, we ...

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 ...

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 ...
