Emilio Lehoucq - Do Americans Think the Digital Economy is Fair? Using Supervised Learning to Explore Evaluations of Predictive Automation
Predictive automation is a pervasive and archetypical example of the digital economy. Studying how Americans evaluate predictive automation is important because it affects corporate and state governance. However, we have relevant questions unanswered. We lack comparisons across use cases using a nationally representative sample. We also have yet to determine what are the key predictors of evaluations of predictive automation. This article uses the American Trends Panel’s 2018 wave (n=4,594) to study whether American adults think predictive automation is fair across four use cases: helping credit decisions, assisting parole decisions, filtering job applicants based on interview videos, and assessing job candidates based on resumes. Results from lasso regressions trained with 112 predictors reveal that people’s evaluations of predictive automation align with their views about social media, technology, and politics.
Abby Smith - The Impact of Entity Resolution on Observed Social Network Structure
Deduplication, also referred to as "entity resolution", is a common and crucial pre-processing step in the construction of social networks. Traditional deduplication methods compare the attributes (such as name and age) of potential matching pairs to estimate a match probability for a pair. In social network datasets, we can also use relational information (e.g., a person’s network ties) in deduplication. My work is focused on methods for evaluating entity resolution in a network setting, measuring the sensitivity of entity resolution results to choices in tuning parameters, and the downstream impacts these parameter choices can have on network metrics and topologies such as degree, closeness, and connectivity. I apply the evaluation methods to two real-world ego-centric network studies, (i) Care2Hope, a respondent-driven sample of rural people who use drugs (PWUD) in Appalachian Kentucky, and (ii) RADAR, a longitudinal network study of young men in Chicago who have sex with men.
Emma Zajdela - Back in Fashion - Modeling the Cyclical Dynamics of Trends
Common wisdom holds that fashion is cyclical, with talk of trends coming "back," from bell-bottom jeans to miniskirts. Historically, a lack of quantitative data posed a barrier to explicit mathematical study of this system, however, newly digitized historical records now make such work possible. This talk will present analysis from a new database we constructed quantifying tens of thousands of images of clothing from 1869 to present day. It will describe approaches to modeling the cyclical dynamics of fashion observed in the dataset. Large-scale social phenomena such as fashion trends are of intrinsic interest themselves, but can also help elucidate the interplay of creativity, differentiation, conformity, and diffusion of ideas in broader human systems.

WED@NICO SEMINAR: Nicole Woitowich, Feinberg School of Medicine "Exploring the Science of Biomedical Science from Discovery to Impact"

Speaker:
Nicole Woitowich, Research Assistant Professor, Department of Medical Social Sciences, Feinberg School of Medicine, Executive Director, NUCATS
Title:
Exploring the Science of Biomedical Science from Discovery to Impact
Abstract:
This presentation explores the biomedical research enterprise from a science of science perspective, focusing on the relationships between research practices, the people who shape them, the policies that govern them, and the public they ultimately aim to serve. A central thread of this work examines the intersection of sex and gender inclusion in research, the advancement of women in science and medicine - and how they may be inextricably related. This talk will explore how sex and gender are included, analyzed, and reported in biomedical research, and how gender disparities within the scientific workforce influences the types of questions asked and how data are reported and analyzed. Together, these dynamics have significant implications for the rigor and reproducibility of research, as well as for health outcomes more broadly. The talk will also reflect on how this science of science perspective can inform ongoing work at Northwestern’s Clinical and Translational Sciences (NUCATS) Institute which aims to improve, innovate, and implement generalizable solutions that enhance the efficiency, quality, and impact of clinical and translational science. The session will conclude with an overview of NUCATS’ initiatives and resources aligned with these goals.

Title:
All-Female and Female-Led Teams Drive More Breakthrough Ideas in Science and Innovation
Abstract:
The increase of female researchers in science over the past decades has initiated many studies on the gender composition of teams and their research outcomes. Substantial evidence underscores the value of including female researchers in science. Yet, their impact on driving new research directions and technological innovation within teams remains underexplored. In this presentation, we analyze over 65 million papers and two million patents spanning 1950-2010. We document the rise in all-female teams and demonstrate that all-female teams consistently produce the highest proportion of disruptive papers. We explore this trend across time periods, team sizes, and fields. We find that despite the overall decline in disruption, notably, all-female teams have the smallest decline in disruption. We analyze publication text, field-specific structural differences, author careers, leadership dynamics, and team dynamics to understand the vital role that all-female teams play in driving breakthroughs.
