You will receive a link to the virtual meeting via email.  \n\n\n\n\nRegister\n\n\n\n\nSocial networks research with digital traces data\n\n\n\nThe emergence of the internet and its various modes of online interaction have created unprecedented opportunities for social scientists to study classic social questions in new ways\, but also to ask new questions. This holds in particular for themes like social networks\, social order\, and cooperation. In this talk I will present various examples of my work over the past years on these themes\, drawing on a variety of different “digital traces” data sources\, including social media and online markets. \n\n\n\nAbout Rense Corten\n\n\n\n\n\n\n\nRense Corten is Associate Professor at the Department of Sociology. His research revolves around the themes of cooperation\, trust\, and (the dynamics of) social networks\, with empirical applications including adolescent networks\, social media\, the sharing economy\, online criminal networks\, and laboratory experiments. In 2016 he received an NWO Vidi grant for a research project on the origins and consequences of trust in the sharing economy.He obtained his PhD in social sciences in 2009 and his doctorate in sociology in 2004 at Utrecht University.

Understanding mechanisms for the emergence of school segregation is crucial for understanding potential policy solutions. A vast literature has identified a number of main factors in school segregation of which residential patterns and school choice are arguably the most important. Drawing on findings from a range of qualitative and quantitative studies\, I will outline the complexity of school segregation and suggest to combine existing approaches with a complexity science perspective. I will present both empirical evidence from the Netherlands and insights from theoretical models. \n\n\n\nAbout Willem Boterman\n\n\n\n\n\n\n\nWillem Boterman is Associate Professor Urban Geography at the University of Amsterdam. He combines qualitative and quantitative methods in his interdisciplinary work into the relationship between spatial and social inequalities. His work is primarily concerned with segregation in neighborhoods and schools\, but also with formations of social class and gender.

You will receive a link to the virtual meeting via email.  \n\n\n\n\nRegister\n\n\n\n\nRethinking one-mode projections\n\n\n\nTwo-mode networks are usually analyzed in one of two ways. With the “direct” approach using methods tailored for bipartite graphs\, or with the “conversion” approach\, which includes all methods that project the two-mode network onto each mode separately.In this talk\, I focus on one-mode projections where one mode serves as the primary mode and the second mode only as a proxy for relations among actors in the primary mode. Drawing parallels to item response theory\, I argue that projected (and dichotomized) ties are conceptually different than traditional ties\, which therefore restricts the applicability and interpretability of standard network analytic tools in such cases. I will introduce a set of alternative methods to analyze one-mode projections and exemplify these with several empirical examples. \n\n\n\nAbout David Schoch\n\n\n\n\n\n\n\nDavid came to Manchester in September 2018 as a Presidential Fellow in Sociology.

Takes DESCRIPTION:Frank W. Takes (Leiden University & University of Amsterdam): Population-scale Social Network Analysis \n\n\n\nAbstract | Country-wide administrative register data\, as studied within the POPNET project\, enables the discovery of population-scale insights into contemporary social scientific problems such as segregation\, inequality\, loneliness and poverty. This talk considers responsibly anonymized population-scale social network data on all 17 million inhabitants of the Netherlands. We discuss how the formal links in this social network require one to critically rethink network analysis concepts such as the unit of analysis\, measurement errors effects and the boundary specification problem\, but also allows us to in a unique way revisit the well-known small-world phenomenon. The talk furthermore presents initial findings on the relation between the network structure and spatial distribution of the population. \n\n\n\nBio | Frank Takes is head of the Computational Network Science Lab at LIACS\, the computer science department of Leiden University. He is also co-PI of the Population-scale social network Analysis (POPNET) platform\, involving a collaboration between Leiden University\, University of Amsterdam and Statistics Netherlands (CBS). His research deals with understanding the connectivity of our highly connected society\, and is fascinated by how complex network structures cause societies or economies to fail or succeed. He is a steering committee member of the International Conference on Computational Social Science and a board member of the Dutch Network Science Society\, an official chapter of the International Network Science Society.

However\, systematic evidence on how firms build global knowledge access is still lacking. In this paper\, we analyse how global work connections relate to differences in the skill composition of employees within companies and local industry clusters. We gather survey data from 10% of workers in a local industry in Sweden\, and complement this with digital trace data to map co-worker networks and skill composition. This unique combination of data and features allows us to quantify global connections of employees and measure the degree of skill similarity and skill relatedness to co-workers. We find that workers with extensive local networks typically have skills related to those of others in the region and to those of their co-workers. Workers with more global ties typically bring in less related skills to the region. These results provide new insights into the composition of skills within knowledge-intensive firms by connecting the geography of network contacts to the diversity of skills accessible through them. \n\n\n\nAbout Lőrincz László\n\n\n\n\n\n\n\nLászló Lőrincz is a Sociologist (Ph.D) at NETI Lab at Corvinus University\, and ANet Lab at Research Centre for Economic and Regional Studies.

However\, although these studies consider the structural\, temporal\, or spatial characters of human interactions they commonly miss one important dimension regarding the socioeconomic status of individuals\, which may largely determine the social structure itself. The uneven distribution of wealth and individual economic capacities are among the main forces\, which shape modern societies and arguably bias the emerging social network. In this talk\, we will discuss a set of results aiming to close this gap through studies relying on various data-driven observations on mobile-phone communication\, bank transaction\, satellite\, online social system and human mobility datasets. We will find that socioeconomic disparities lead to segregation patterns not only in space but in the social network structure and mobility patterns of people. \n\n\n\nAbout Márton Karsai\n\n\n\n\n\n\n\nMárton Karsai\, PhD\, Habil.\, is an Associate Professor in the Department of Network and Data Science at the Central European University\, researcher at the Rényi Institute of Mathematics\, and fellow of the ISI Foundation in Torino.

You will receive a link to the virtual meeting via email.  \n\n\n\n\nRegister\n\n\n\n\nUsing networks to study inequality: two examples \n\n\n\nDo daily decisions and social interactions reproduce socioeconomic inequality? Limited resources could drive self-defeating behaviour\, strain interactions with others\, and restrict access to valuable information in ways that reinforce people’s disadvantaged position\, while already abundant resources could beget additional advantages in ways that make the rich richer. I will present two projects that use radically different computational and analytical methods to address this general hypothesis. In the first example\, we conduct online network cooperation experiments to study whether the visibility of outcome-relevant resources (ability\, intelligence\, knowledge\, etc.) and the visibility of wealth could improve inequality. In the second example\, we analyse the bipartite network of verified Twitter accounts of companies\, brands\, and organizations and their followers to estimate the socioeconomic status of individual Twitter users.  \n\n\n\nAbout Milena Tsvetkova \n\n\n\n\n\n\n\nMilena Tsvetkova is Assistant Professor of Computational Social Science at the Department of Methodology at the London School of Economics and Political Science.

Over the course of careers\, workers build social networks to other workers through shared institutional and organizational histories. For a long time\, scholars have studied how such networks enable and constraint the mobility of workers\, shaping horizontal movement across workplaces as well as vertical movement in the occupational structure. In this talk we theorize the relative importance of different configurations of worker ego networks in enabling social mobility in labor markets\, along with their changing utility across different occupational careers. \n\n\n\nWe consider family\, education-\, workplace-\, and resident-based ties to co-workers and managers and provide a theoretical framework that link synergies between the type\, strength and power asymmetry of social ties to horizontal and vertical mobility outcomes. We present various analytical strategies for identifying workers’ network configurations and for testing the relative importance of different configurations on different mobility outcomes. Combining linked employer-employee data with population registers and educational records we reconstruct workers’ network configurations as they move between workplaces. By combining dynamic multimodal network data with mobility outcomes across workers’ careers we are able to demonstrate the multiple pathways by which networks inform labor market mobility.  \n\n\n\nAbout Lasse Folke Henriksen\n\n\n\n\n\n\n\nLasse Folke Henriksen is Associate Professor at Copenhagen Business School.

This study focuses on the phenomenon of corruption in a bureaucratic context\, in one of the most corruption-prone sectors – public procurement. In their attempts to fight institutionalized grand corruption\, governments all over the world improve the regulatory frameworks to ensure transparent and efficient public procurement market. One of the recent developments in the field was a successful launch of the ProZorro public procurement platform in Ukraine that achieved recognition all over the world as one of the best procurement reforms. Despite the enormous effort invested in the development of the transparent and efficient public procurement platform\, it is too early to conclude that ProZorro successfully eliminated corruption. Hence\, this study sets out to precisely estimate the prevalence and distribution of corruption risks in ProZorro. Overall\, we find that ProZorro faces issues related to the lack of competition such as a low number of suppliers and a high share of single bidding contracts in some of the procurement markets. To tackle these issues\, we develop a risk assessment tool for policymakers that could signal higher corruption risks in tendering processes. \n\n\n\nAbout Yuliia Kazmina \n\n\n\nYuliia Kazmina is a PhD Candidate at the POPNET project.

First\, I am going to show how commuting distance conditions the online social ties of Twitter users in the 50 largest metropolitan areas of the United States. Home and work locations are identified from geolocated tweets that enable us to infer the socio-economic status of individuals. The results suggest that commuting-enabled mixing manifests in reduced levels of income assortativity in online social relationships suggesting a universal role of commuting in integrating disparate social networks in cities. Second\, I am going to talk about the difference between the spatial concentration of social ties around people’s home and work locations\, and how the concentration around the home locations is stronger for people with lower socio-economic status\, whereas higher status users have a higher social connection density around their workplaces. These differences between the poor and the rich can also be observed in certain structural metrics of the ego-networks linked to social capital such as the clustering coefficient and the share of supported ties. This suggests that the structure of social networks around homes provide greater social capital for poor users than for rich users. \nAbout Eszter Bokányi\nEszter Bokányi is a research postdoc in the POPNET project investigating a population-scale longitudinal social network of the Netherlands. She has a background in physics\, and graduated with a PhD from statistical physics at Eötvös Loránd University in Budapest. The topic of her thesis was already rather connected to computational social science\, having investigated a huge database of geolocated Twitter messages.Nowadays\, she is still mostly interested in spatial social networks and their connection to human mobility\, as well as dynamical phenomena such as the spreading of innovations over these social networks.\n \n \n\n\nAbout POPNET Connects\n\n\n\nPOPNET Connects is the seminar series of the Population Scale Network Analysis (POPNET) platform. We invite everyone to join the seminar\, connect with others and get involved in discussion.
