Foreword: Resisting Erasure: Libraries In Palestine And Palestine In Libraries, Emily Drabinski Mar 2026

Foreword: Resisting Erasure: Libraries In Palestine And Palestine In Libraries, Emily Drabinski

Publications and Research

This foreword opens an anthology that explores research and experiences at the intersection of Palestine and libraries. Part one examines how Palestinian librarians, archivists, and individuals resist erasure by preserving Palestinian materials and narratives and by ensuring Palestinians’ access to library resources amidst recurring cycles of destruction and confiscation. Part two explores how librarians in the United States respond to pressure from right-wing and pro-Israel advocacy groups that are quick to label any effort to include Palestinians and their histories as antisemitic.


Bundled Guidance Types And Changes In Expected Volatility, Thaddeus Neururer, George Papadakis Mar 2026

Bundled Guidance Types And Changes In Expected Volatility, Thaddeus Neururer, George Papadakis

University Research

We examine how different types of bundled managerial guidance affect uncertainty levels around earnings announcements. To measure changes in uncertainty, we use both changes in implied volatilities and methods that decompose the implied volatility term structure. Unlike prior studies, we find little evidence that earnings guidance is associated with investor uncertainty. Our results instead indicate that other forms of bundled guidance are associated with lower uncertainty levels. Revenue, capital expenditure, and earnings before interest, taxes, depreciation, and amortization guidance are strongly associated with reductions in investor uncertainty, even when firms provide earnings guidance.

Parent-Child Interactions Across Contexts And Children’S Adaptive Classroom Behaviors In Second Grade, Hannah Dalton Mar 2026

Parent-Child Interactions Across Contexts And Children’S Adaptive Classroom Behaviors In Second Grade, Hannah Dalton

Honors Program: Senior Projects (Public)

Adaptive classroom behaviors are important for children’s success in the classroom by supporting their abilities to learn academic concepts and positively engage with peers. Research indicates that parents’ behaviors during interactions with their children are important for their social and academic outcomes, but there may be variance in parents’ behaviors based on their goals for the interaction. The current study examined interaction quality across three parent-child interaction tasks and correlations with their second-grade children’s adaptive classroom behaviors. The sample included 170 second-grade children and their parents who completed three joint tasks: a puzzle task, a homework task, and a conflict …

Contraceptive Autonomy Of Adolescents And Young Adults In The U.S. South: The Influence Of Healthcare Providers, Partners, And Parents, Kathleen Broussard, Laura D. Lindberg, Emily S. Mann Mar 2026

Contraceptive Autonomy Of Adolescents And Young Adults In The U.S. South: The Influence Of Healthcare Providers, Partners, And Parents, Kathleen Broussard, Laura D. Lindberg, Emily S. Mann

Faculty Publications

A growing body of research describes coercive experiences in contraceptive care in the clinic setting, a phenomenon that disproportionately constrains the contraceptive autonomy of women who are young, low-income, Black, or Latinx. Less research has examined how other social influences may constrain contraceptive use and decision-making. We examine contraceptive autonomy across three domains of interpersonal influence (healthcare providers, sexual partners, and parents) and by race (Black vs. White). Between July–September 2023, we surveyed 1207 Black and White adolescents and young adults (AYAs) assigned female at birth living in five southern states. Over half of all respondents reported feeling social pressure …

Resting-State Eeg Spectral Activity In Children And Adolescents With Asd: Potential Correlations With Interoceptive Neocortical Areas, Stephanie J. Morris Mar 2026

Resting-State Eeg Spectral Activity In Children And Adolescents With Asd: Potential Correlations With Interoceptive Neocortical Areas, Stephanie J. Morris

Dissertations

Autism spectrum disorder (ASD) is a developmental condition marked by impairments in social interaction, communication, repetitive behaviors, and differences in cognitive and emotional functioning. These challenges can significantly affect daily living, relationships, and long-term independence, often requiring lifelong support. Emerging research suggests that deficits in interoceptive processing—the ability to perceive internal bodily states—may contribute to ASD symptoms and represent a potential target for intervention.

This study aims to compare resting-state EEG (QEEG) activity between children and adolescents with ASD and neurotypical (TD) peers, and to explore the relationship between interoceptive processing and ASD diagnosis. Archival QEEG data from individuals aged …

Evaluating Youth Programs With Intention: Integrating Developmental Research For A Youth-Centered Approach, Brittany Hite, Tiffany Berry, Evangelia Theodorou, Michelle Sloper

Journal of Youth Development

Conducting applied research or program evaluations in youth settings requires a unique combination of expertise. Although evaluation approaches provide general guidance on how to conduct high-quality evaluations, they rarely provide specific guidance on how to engage in evaluation with organizations serving youth. Fortunately, the field of youth development provides extensive information about how youth develop, facilitators of and influences on youth development, and important considerations for collecting data from this population. This paper provides an approach to evaluation that integrates youth development research. By integrating this literature into their evaluation practice, the authors identified two underlying principles (contextual sensitivity and …


Differences In Student Basic Need Satisfaction Across University Community Service Offerings In Vietnam, Myles Lynch, Nguyen Lam Phuong, Duong Ngoc Anh, Huy Ngoc Vu, Hoang Quang Thang Mar 2026

Differences In Student Basic Need Satisfaction Across University Community Service Offerings In Vietnam, Myles Lynch, Nguyen Lam Phuong, Duong Ngoc Anh, Huy Ngoc Vu, Hoang Quang Thang

Journal of Youth Development

In 2018, the Vietnam Ministry of Education and Training (MOET) made experiential learning a mandatory component of general education in an effort to enhance student skills pertaining to career and professional success. Community service, as a form of experiential learning, can enable individuals to apply knowledge and skills to address societal challenges beyond classroom settings. The availability and effectiveness of structured community service-learning programs vary across Vietnamese universities. Using Basic Needs Theory (autonomy, competence, relatedness), a sub-theory of Self-Determination Theory, this study examined differences in Vietnamese student need satisfaction based on availability of community service courses, providing insights into program …

Improving Agent Retention By Documenting The Impact Of 4-H In Kentucky, Ken Culp, Kimberly Ragland, Tori Stanton, Katherine L. Thompson

Journal of Youth Development

The purpose of this study was to improve agent retention by documenting the positive impact that 4-H agents were making by identifying the most effective program delivery methods in Kentucky. This could help agents prioritize their time, emphasizing high-impact activities. Agents indicated that while one year of 4-H makes the greatest impact, 10 years’ membership is ideal. The most impactful delivery methods were clubs and camps. The most important life skills developed in 4-H were communication, leadership, and community service. Club programming includes all highly valued core experiences identified in this study (leadership opportunities, community service, and communication).

Cyborgs In The Chat: Technological Objects And Sociotechnical Interaction On Twitch.Tv, Yanro Judd C. Ferrer Mar 2026

Cyborgs In The Chat: Technological Objects And Sociotechnical Interaction On Twitch.Tv, Yanro Judd C. Ferrer

Sociology & Anthropology Department Faculty Publications

This paper introduces the concept of Cyborgification, derived from the metaphor cyborg of Donna Haraway, to analyze how technological objects, such as emotes, bots, and third-party extensions, co-construct social life on Twitch.tv. Drawing on digital ethnography and interviews, it examines how viewers and streamers interact not just with each other but with the platform’s technical features in the production of humor, identity, and belonging. Through three scenes, a media-triggered emote ritual, a bot glitch turned joke, and an outsider’s exclusion due to missing plug-ins, this work shows how technological entanglement shapes participation. Cyborgification offers a sociotechnical lens that moves beyond …

Emergency Department Boarding for Psychiatric Care: The Effect of PointClickCare Integration

Abstract

For many individuals in psychiatric crisis, the emergency department has become the first place to seek help, highlighting gaps in how behavioral health care is accessed and coordinated. In Massachusetts, PointClickCare's Behavioral Health Treatment and Referral Platform (BH TRP) was implemented to centralize and streamline referrals between emergency departments and inpatient psychiatric facilities. This capstone evaluates whether implementation of the BH TRP was associated with changes in psychiatric boarding time at a community hospital emergency department. Using a mixed-methods program evaluation design, this study analyzed de-identified electronic medical …

The Changing Landscape Of International Development: An Introduction, Pascaline Dupas, Pinelopi Goldberg, Rohini Pande Mar 2026

The Changing Landscape Of International Development: An Introduction, Pascaline Dupas, Pinelopi Goldberg, Rohini Pande

Cowles Foundation Discussion Papers

Since the late 1980s, extreme poverty has declined sharply, life expectancy and schooling have increased, and electoral democracy has expanded. However poverty reduction has slowed in recent years, particularly following the COVID-19 pandemic, amid intensifying conflict, fragility, climate risks, democratic backsliding, and the erosion of global trends—including trade integration and geopolitical stability—that once supported growth. These dynamics raise three interrelated questions: what barriers impede further progress; where will future growth in lower-income countries come from; and how can growth be broadly shared. Taking stock of 15 chapters forthcoming in Volume 6 of the Handbook of Development Economics, we discuss how …


The Geometry Of Learning Under Ai Delegation, Lingxiao Huang, Nisheeth K. Vishnoi Mar 2026

The Geometry Of Learning Under Ai Delegation, Lingxiao Huang, Nisheeth K. Vishnoi

Cowles Foundation Discussion Papers

As AI systems shift from tools to collaborators, a central question is how the skills of humans relying on them change over time. We study this question mathematically by modeling the joint evolution of human skill and AI delegation as a coupled dynamical system. In our model, delegation adapts to relative performance, while skill improves through use and decays under non-use; crucially, both updates arise from optimizing a single performance metric measuring expected task error. Despite this local alignment, adaptive AI use fundamentally alters the global stability structure of human skill acquisition. Beyond the high-skill equilibrium of human-only learning, the …


Thin Sets Are Not Equally Thin: Minimax Learning Of Submanifold Integrals, Xiaohong Chen, Wayne Yuan Gao Mar 2026

Thin Sets Are Not Equally Thin: Minimax Learning Of Submanifold Integrals, Xiaohong Chen, Wayne Yuan Gao

Cowles Foundation Discussion Papers

Many economic parameters are identified by “thin sets” (submanifolds with Lebesgue measure zero) and hence difficult to recover from data in an ambient space. This paper provides a unified theory for estimation and inference of such “thin-set” identified functionals. We show that thin sets are not equally thin: their intrinsic dimensionality m matters in a precise manner. For a nonparametric regression h0 with Hölder smoothness s and d-dimensional covariates in the ambient space, we show that n^{-s/(2s+d−m)} is the minimax optimal rate of estimating linear and nonlinear (e.g., quadratic, upper contour) integrals of h0 on an m-dimensional submanifold (0 ≤ …


Screening And Segmenting: A Consumer Surplus Perspective, Dirk Bergemann, Tibor Heumann, Michael C. Wang Mar 2026

Screening And Segmenting: A Consumer Surplus Perspective, Dirk Bergemann, Tibor Heumann, Michael C. Wang

Cowles Foundation Discussion Papers

We analyze consumer surplus when a monopolist can adjust both prices and prod-uct qualities across segments, engaging in second- and third-degree price discrimination simultaneously. We characterize the consumer-optimal segmentation and show that it has a striking structure: consumers with the same value receive the same quality in every segment, though prices differ. Under mild conditions, any segmentation harms consumers if and only if demand is sufficiently more elastic than supply. Hence, po-tential benefits for consumers depend critically on demand and supply elasticities. These findings have implications for regulatory policy regarding price discrimination and market segmentation.


Identifying Common Trend Determinants In Panel Data, Yoonseok Lee, Peter C.B. Phillips, Suyong Song, Donggyu Sul Mar 2026

Identifying Common Trend Determinants In Panel Data, Yoonseok Lee, Peter C.B. Phillips, Suyong Song, Donggyu Sul

Cowles Foundation Discussion Papers

This paper develops a novel method for identifying observable determinants of latent common trends in nonstationary panel data, which are typically removed or controlled in two-way fixed effects regressions. By examining cross sectional dispersion processes, we assess whether panel series exhibit distributional convergence toward specific observed time series, revealing them as long run determinants of the underlying latent trend. The approach also offers a new perspective on cointegration between time series and panel data, focusing on the relative variation of the panel data with respect to the cointegration error. Applying this method to U.S. state-level crime rates demonstrates that the …
