Alina Arseniev-Koehler, Assistant Professor, Sociology, Purdue University
Title:
Stigma’s Uneven Decline
Abstract:
Has the stigma targeting diseases declined? We analyze 4.7 million news articles to create new measures of stigma for 106 health conditions from 1980-2018, using word embedding methods for text analysis. We then examine how this stigma changed for different types of conditions across time using mixed effects regression modeling. We find that in the 1980s, most diseases were marked by strong connotations of disgust, immorality, and negative personality traits. Since then, stigma declined dramatically for chronic illnesses: cancers, neurological conditions, genetic diseases, and many other conditions have shed most of their negative connotations. But for other types of conditions, stigma proved especially resistant to change. Across the decades, behavioral health conditions (mental illnesses, addictions, and eating disorders) persistently connoted immorality and negative personality traits. Infectious diseases remained strongly linked to attributions of disgust. Stigma has transformed from a sea of negative connotations surrounding most diseases to a narrower set of judgments targeting conditions where the primary symptoms are aberrant behaviors. (This talk is based on research with Rachel Best at the University of Michigan).
Speaker Bio:
Alina Arseniev-Koehler is a computational and cultural sociologist with substantive interests in language, health, and social categories. Alina strives to clarify core concepts and debates about cultural meaning in sociology. For example, how do individuals learn and deploy stereotypes? Empirically, Alina focuses on cases where meaning is linked to inequality and health, such as the moral meanings attached to body weight, the stigmatizing meanings of disease, and gender stereotypes. To investigate these topics, Alina uses computational methods and machine learning, especially computational text analysis.
Alina’s work also circles around a methodological question: how can scientists measure meanings encoded in text data, such as news articles and social media posts? Computational text analysis requires scientists to mathematically model the nuanced ways in which human language encodes and conveys meaning. As highlighted by Alina’s work, innovation in computational text analysis is tightly intertwined with innovation in theoretical understanding of meanings.
Alina received a B.A. in Sociology from University of Washington in 2014, and a master’s and Ph.D. in Sociology from the University of California, Los Angeles in 2022.

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.

WED@NICO SEMINAR: Diego Gomez-Zara, University of Notre Dame "All-Female and Female-Led Teams Drive More Breakthrough Ideas in Science and Innovation"

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.
