Tim Hannigan to present in the SONIC speaker series

No Comments

Tim Hannigan will be presenting a SONIC speaker series talk at 2:30pm on February 27th in room 1-421 of the Frances Searle Building. Tim is a Doctoral Candidate at the Saïd Business School, University of Oxford.

In his upcoming talk, Tim will focus on his research on the evolution of product ontologies. As
cognitive representations packaging up product attributes, use-cases and buyer
characteristics, these knowledge structures become embedded as market categories.
This talk will show that the fuzzy-front end of a product market is marked by ambiguity
and uncertainty around definitions and concepts that appear in the form of rumour.
Using a computer-aided text analysis on discourse of “tech-bloggers”, Tim will show that
this uncertain knowledge is refracted by social media into semantic networks that
demonstrate the emergence of meaning structures.

Edward Smith SONIC Speaker Series

No Comments

On Monday, February 6, from 9:30-11:00 a.m. Dr. Edward (Ned) Smith will be giving a presentation in room 1-483 of the Frances Searle Building on the Northwestern University Evanston Campus. The talk is entitled “Identity and Network Activation”.

About the talk
In his talk Ned will focus on his research on Identity and Network Activation. Using a dynamic cognitive model of network activation, Ned and his colleagues experimentally test two com peting hypotheses on the link between identity and network activation. On one hand, affirming people’s power might enable agency. On the other hand, if such power affirmations conflict with people’s more stable status characteristics, this could create tension. These hypotheses were tested experimentally by priming people at varying levels of status with power
(high/low) and social change (significant/none) and asking them to recall their social networks. Results suggest that stable, confirmed identities, and not feelings of power, are the foundation from which people can exhibit greater network responsiveness.

About Ned Smith
Ned Smith is an Assistant Professor of Strategy at the Stephen M. Ross School of Business, University of Michigan. He received his Ph.D. from the University of Chicago Booth School of Business prior to joining the faculty at Ross in 2010. His research focuses on the construction and consequences of organizational identity, with an emphasis on financial markets. He draws on sociological and network theories to develop and test new identity-based models of organizational behavior and investor decision-making. He also studies how people mentally construct their social worlds -i.e., their social networks- according to situational and environmental variations. Ned’s research has been published or is forthcoming in leading journals such as the American Journal of Sociology, The Journal of Mathematical Sociology, Management Science, and Organization Science.

On Friday, December 2, from 2:15-3:30 p.m. Dr. Griffin M Weber will be giving a presentation in room 1-421 of Frances Searle Building on the Northwestern University Evanston Campus. The talk is entitled “Social Network Analysis Using Harvard Catalyst Profiles”. Harvard Catalyst Profiles is an open source, ontology based, research networking software platform that creates research profiles for an institution’s faculty, and links these together through both Passive Networks, which are automatically generated based on information known about investigators, and Active Networks, which users themselves create by indicating their relationships to other researchers. These networks have numerous applications, ranging from finding individual collaborators and mentors to understanding the dynamics of an entire research community. Harvard Catalyst Profiles is used by institutions around the world and has an active user community with multiple software development teams contributing to the platform.

Roger Leenders SONIC Speaker Series

No Comments

Prof. Roger LeendersOn Thursday, October 27, from 1:00-2:00 p.m. Prof. Dr. Roger Leenders will be giving a presentation in Room 1-483 of Frances Searle Building on the Northwestern University Evanston Campus. The talk is entitled “Competition and the Gender of Team Creativity”. The presentation reports on several studies on the effect of interteam competition on the creativity of teams. In particular, a recent study proposing that having groups go head-to-head is stimulating to the creativity of groups composed of men but detrimental to the creativity of groups composed of women. Lab studies showed differential effects of competition on the creativity of male versus female groups, especially at the higher end of the competition spectrum. The researchers also found that, based on network theory, these effects were mediated by in-group collaboration. The effects were also replicated in a field setting involving R&D teams.

Ackland to lead Hyperlink Network Analysis Workshop

No Comments

On Friday, October 7th, from 10:00-12:00p.m. Robert Ackland will be leading a workshop on Hyperlink Network Analysis in Frances Searle Room 1-459 on Northwestern University’s Evanston Campus.

If you plan to attend, please email Marilyn Logan: mjlogan@northwestern.edu, by Thursday, September 29.

This presentation will involve a demonstration of hyperlink network analysis using two software packages: the VOSON System (a web-based application for hyperlink
network construction and analysis) and VOSON+NodeXL (a VOSON plugin to the NodeXL Excel 2007/2010 template for social media network analysis). Topics covered
include: creating a hyperlink network (identifying seed URLs, setting the webcrawler parameters); node preparation (methods for filtering and controlling the grouping of web pages); coding of node attributes; basic social network analysis metrics; network visualization; clustering; website content analysis. Participants wanting to use the software are requested to bring their laptops with Mozilla Firefox and VOSON+NodeXL installed, and must have (free) VOSON user account.
See http://voson.anu.edu.au and http://www.uberlink.com for information on the VOSON project and software. See http://nodexl.codeplex.com for information on NodeXL.

Robert Ackland is a Fellow at the Australian National University, where he conducts empirical social science research into online social and organizational networks. He leads the VOSON project http://voson.anu.edu.au, coordinates the ANU’s Master of Social Research programme and teaches on the social science of the Internet and online research methods. Robert has degrees in economics from the University of Melbourne, Yale University (where he was a Fulbright Scholar) and the ANU, where he gained his PhD in 2001.
