The Making of a French Migration Crisis
15 June 2022

Dr Michelle Reddy and Dr Hélène Thiollet

Center for International Research (CERI) at Sciences Po

Mass inflows of migrants are believed to create public anxiety and impact attitudes and votes. However, few scholars have systematically explored the construction of migration as a crisis.

In this session of the CIVICA Data Science Seminar Series, Dr Michelle Reddy and Dr Hélène Thiollet used automated text analysis on a longitudinal dataset extracted from French newspapers to locate the emergence of 'migration crisis' discourse in 2015. Absent massive inflows of migrants or refugees in France contrary to other European countries, this showcases a politicised framing of a humanitarian issue that might have created a sense of slow-burning crisis in French society.

A New Approach to Visualizing Spatial Exposure Data for Comparing Earthquakes
1 June 2022

Professor Stephanie Lackner

Assistant Professor in Economics at the IE Business School and the School of Global and Public Affairs at IE University

The comparison of different earthquakes is a popular tool to highlight particular aspects of one or several events. The objective is usually to demonstrate differences in the social conditions and how those affect the outcome of earthquake impacts. While earthquake magnitude is always presented in such comparisons, earthquake shaking is often not considered, even though shaking is the crucial determinant for impacts. Whenever differences in shaking are discussed, these discussions usually provide technical details that describe why the shaking was different and neglect to present how the shaking was different.

In this session of the CIVICA Data Science Seminar Series, Professor Stephanie Lackner, demonstrated an approach that utilizes two separate but complimentary steps of data visualizations which can facilitate an effective communication of earthquake shaking and population exposure data to non-experts.

Modeling Sustainable Development from the Bottom Up: Coupling Open Data and Agent Computing to Inform Policy Prioritisation
4 May 2022

Miss this event? A recording is available here.

Dr Omar A Guerrero

Head of Computational Social Science Research
The Alan Turing Institute.

The explicit acknowledgement of the complexity of the Sustainable Development Goals (SDGs) is one of the main innovations of this international agenda. However, the formal analysis of complex systems in the SDG literature remains scant, as most of the focus is given to (top-down) aggregate models such as systems dynamics and networks of indicators.

In this talk, Omar argued that an adequate treatment of complexity needs to look at development as a bottom-up process, with macro-level outcomes emerging from micro-level interventions. From a quantitative point of view, popular methodologies such as statistical analysis and machine learning are inadequate to deal with this vertical causation since the existing data are aggregate and coarse grained (typically annual development indicators). To resolve this, models with explicit agent-level causal mechanisms are needed, and agent computing is the right tool to create them. Omar presented the research program of Policy Priority Inference, which employs agent computing to model the SDGs from the perspective of public expenditure interventions. Omar discussed several applications related to policy coherence, policy resilience, feasibility, fiscal federalism, accelerators, and bottlenecks; as well as the country-case studies in which they have been applied. This programme provides a fresh perspective to the challenges of multidimensional development, and a rigorous approach to exploit not only indicators, but also new sources such as open spending data.

The Science of Success: Quantifying Outcomes in Social Systems
9 March 2022

Professor Albert-László Barabási

Professor of Network Science at Northeastern University and Director of the Center for Complex Network Research

Our current approach to success is driven by the belief that predicting exceptional impact requires us to detect extraordinary ability.

Despite the long-standing interest in the problem, even experts remain notoriously bad at predicting long-term impact. Success becomes suddenly predictable, however, if we see it not as an individual but a collective phenomenon: for something to be successful, it is not enough to be novel or appealing, but we all must agree that it is worthy of praise.

If we accept the collective nature of success, its signatures can be uncovered from the many pieces of data around us using the tools of network and data science.

In this talk, Professor Albert-László Barabási focused on a general, quantitative theory of success and signal the emergence of a new research field - The Science of Success.

Embedding Regression: Models for Context-Specific Description and Inference
23 February 2022

Professor Arthur Spirling

Professor of Politics and Data Science at New York University

"Political scientists commonly seek to make statements about how a word’s use and meaning varies over circumstances—whether that be time, partisan identity, or some other document-level covariate. A promising avenue is the use of domain-specific word embeddings, that simultaneously allow for statements of uncertainty and statistical inference."

In this session, Professor Arthur Spirling, introduced the a la Carte on Text (ConText) embedding regression model for this purpose and evaluate how this method outperforms well-known competitors for studying changes in meaning of words across groups and time.

Information and Irregular Migration: Evidence from a Field Experiment in Nigeria
9 February 2022

Dr Alexandra Scacco

Senior Research Fellow in the Institutions and Political Inequality unit at WZB

Policy projections and recent research suggest that large numbers of migrants from sub-Saharan Africa will continue to attempt to make their way to Europe over the next few decades. In response, European countries have made and continue to make significant investments in information campaigns designed to discourage irregular African migration. 

Dr Alexandra Scacco from WZB Berlin led us through her team's research and field experiment on the effects of having detailed, accurate information about features of the journey along the “Mediterranean route”. Alex explored migration-related risks, interest in attempting irregular migration, and actual migration from households in Nigeria, helping to shed some light on why and how certain groups of people choose to embark on this migration journey.

Understanding Social Media censorship with Text Matching

Professor Margaret Roberts

Associate Professor in the Department of Political Science at the University of California, San Diego and co-director of the China Data Lab at the 21st Century China Center.

 
"Social media users in China are censored every day, but it is largely unknown how the experience of being censored affects their future online experience. Are social media users who are censored for the first time flagged by censors for increased scrutiny in the future? Is censorship 'targeted' and 'customised' toward specific users? Do social media users avoid writing after being censored? Do they continue to write on sensitive topics or do they avoid them?"

This is the opening to the latest research on Adjusting for Confounding with Text Matching by Professor Margaret Roberts and her research team, Brandon Stewart and Rich Nielsen.

In this session, Margaret shared how the method of text matching can help to address the problem of confounding in observational studies which ultimately supports credible causal inferences about the effects of experiencing censorship. She also validated her research approach and illustrated the importance of conditioning on text to address confounding with two applications: the effect of perceptions of author gender on citation counts in the international relations literature and the effects of censorship on Chinese social media users.

Speaker

Professor Chris Bail

Professor of Sociology and Public Policy at Duke University

In an era of increasing social isolation, platforms like Facebook and Twitter are among the most important tools we have to understand each other. We use social media as a mirror to decipher our place in society but, it functions more like a prism that distorts our identities, empowers status-seeking extremists, and renders moderates all but invisible.

In this seminar Professor Chris Bail explores the minds of these online extremists and offers innovative solutions to counter this political tribalism.
