Knowledge and Experience in two-mode temporal networks
Professor and Chair, Network Analysis, University of Manchester
Two mode social network data consisting of actors attending events is a common type of social network data. For these kinds of data, in these cases it is also common to have additional information about the timing or sequence of the events. We call data of this type two-mode temporal data. We explore the idea that actors attending events gain information from the event in two ways. Firstly the event itself may provide information or training; secondly, as co-attendees interact, they may pass on skills or information they have gleaned from other events. We propose a method of measuring these gains and demonstrate its usefulness using the classic Southern Women Data and a covert network dataset.

User Linkage in Online Social Networks
Lim Ee Peng
Professor, Information Systems, Singapore Management University
Director, Living Analytics Research Centre
The popularity of social media has led many users to create accounts with different online social networks. Identifying these multiple accounts belonging to same user is of critical importance to user profiling, community detection, user behavior understanding and product recommendation. Nevertheless, linking users across heterogeneous social networks is challenging due to large network size, heterogeneous user attributes, and noises in user generated data. In this talk, we shall introduce different approaches to link users across heterogeneous social networks, overcoming the above challenges. We will also feature Linky, a platform that is designed to evaluate user linkage accuracies returned by different user linkage methods.

Network Diversity and the link to National Identity and Social Cohesion
Associate Professor, Sociology, National University of Singapore
Examining the social networks of some 3,000 Singapore residents using representative data collected in 2016, this study examines the link between a variety of network diversities and national identity and trust toward other groups. We hypothesize a positive relationship occurring between them based on the idea that forging ties with a variety of different others (e.g., different race or class or religion) generates understanding between groups, dismantles silos, enhances a national identification and strengthens trust between groups. The study adds to a growing literature on the effects of network diversity on social cohesion.
Vincent Chua is an Associate Professor in the Department of Sociology at the National University of Singapore. He received his PhD in Sociology from the University of Toronto in November 2010. His main research interests are in social networks, education, and social stratification. He has published widely in international journals including Social Networks, Social Science Research, Current Sociology, Comparative Sociology, Sociological Perspectives, International Studies in the Sociology of Education, American Behavioral Scientist and Environment and Planning C. He received the Faculty Teaching Excellence Award in 2013 and 2017 and the Annual Teaching Excellence Award in 2017.
Investigating Ecological Influence and Casual Contact Network Effects: An Introduction to Blau Status Methodology
Assistant Professor, Sociology, Singapore Management University
The talk introduces a methodological framework to investigate ecological influence processes. It is premised on McPherson's (1983) Blau space and affiliation ecology model and represents a powerful framework for analyzing the ecological competition among social entities, such as organizations, along a combination of sociodemographic characteristics of their members. A central idea to this framework is that of a Blau status, which is a positional attribute derived from an individual’s Blau space location in the affiliation ecology. There are a variety of Blau statuses and the talk will present both network-dependent and network-independent statuses. Blau statuses exert their effect via casual social network ties and thus can act as a proxy of casual contacts, which are otherwise difficult to measure. This talk will be divided into four parts. First, it will explain the theoretical framework and motivation behind the method. Second, it will present the methodological framework that underpins the method with an empirical example of a published study on the spread of two kinds of behaviors as well as a current study on identifying members of delinquent social groups. Third, it will describe the software developed for the investigation of Blau Space analysis called Blaunet (available for free as an R library). Fourth, it will discuss some of the directions that Blau status methodology can be extended.
Michael Genkin is an Assistant Professor of Sociology at Singapore Management University. He received his PhD in Sociology from Cornell University in 2014. His main research interests are social network analysis and political sociology. His current research aims to develop the method of Blau Status Analysis to model and understand a range of human behaviors. His second research stream seeks to understand the ecological forces that explain how individuals and organizations adopt political violence as a strategy. His work appeared in the American Journal of Sociology, American Sociological Review, Social Networks, Social Science Research, and Journal of Conflict Resolution.
