Black Ecological Care: Conservation, Environmental Justice, And Sovereignty In Baltimore, Maryland, Alexandria Nicole Casteel

Dartmouth College Ph.D Dissertations

Dominant traditions of urban planning, municipal policy, and environmental science register Black urban spaces through a vocabulary of pathology, as sites of ecological deficit, contamination, and social decay. This dissertation investigates how Black communities in U.S. cities attend to the environment in ways that address legacies of environmental and social injustice while opening pathways toward different environmental futures. I gather these practices under the analytic of Black ecological care, which captures the generative labor of making and maintaining livable worlds within, alongside, and beyond histories of harm. I develop the analytic across twenty-nine months of ethnographic fieldwork in 2021 and …

From Meaning To Memory: Assessing The Capacity And Representational Structure Of Visual Working Memory With Meaningful Stimuli, Yong Hoon Chung

Dartmouth College Ph.D Dissertations

Visual working memory is thought to be strictly limited. Yet we remember meaningful, real-world objects better than abstract stimuli. Here I show that this advantage arises from the semantic structure of meaningful objects, not their perceptual features alone, and that it extends even to memory for associated features such as color. In the brain, meaningful objects elicit greater and more distributed delay activity, consistent with the recruitment of higher-level neural processes during maintenance. I propose that semantic knowledge adds representational dimensions that make items more distinctive, and that these dimensions are organized hierarchically with lower-level visual features. These findings recast …

The Effects Of Episodic Facilitation And Immersion On Memory Formation During Learning Of An Exterior Preflight Inspection Procedure, Nathan A. Sonnenfeld

Graduate Studies Theses and Dissertations 2026

This research examined the use of episodic facilitation—instructional elements aligned with episodic memory (EM) processes—to affect learners’ memory of simulation training for an aviation procedure. Despite its assumed benefits in industry and theory, virtual reality (VR) has shown limited advantages over conventional media for training procedures, in part because prevailing frameworks emphasize semantic and procedural outcomes, leaving memory of training experiences as events underexamined. To address this gap, this work advances human factors research by examining EM as a design consideration, an outcome, and an explanatory mechanism for how simulation training experiences are remembered. Grounded in theories of EM and …

Grandmothers Of Invention: A Commentary On Fifty Years Of Hazards And Disasters Research And Practice In The United States, Susan L. Cutter, Kathleen Tierney

Faculty Publications

This commentary highlights the role of “grandmothers of invention”: women in the United States who were the first to enter the field of hazards and disasters as core researchers and who played key roles in advancing the science and practice of hazards/disasters research since 1975. We examine the evolution and transformation of the field from the perspective of the women who were initially entering a male-dominated field. The innovations in theory, concepts, tools, topics, and mentoring the next generation of scholars and practitioners are highlighted. Notably, emphasis on these women's singular and collective influence on practice and policy highlights the …

The Effects Of Psychological Counseling Types On Stress, Athlete Burnout, And Resilience In Athletes: Ai Chatbot Vs. Face-To-Face Counseling, Ga-Young Kim, Hye Jin Yang, Chulhwan Choi, Chul-Ho Bum

Human Movement Studies & Special Education Faculty Publications

This study examined the effects of artificial intelligence (AI) chatbot counseling and face-to-face counseling on perceived stress, athlete burnout, and resilience among athletes. In this three-arm quasi-experimental pretest–posttest study, 73 athletes participated in AI chatbot counseling, face-to-face counseling, or a control condition over a 12-week intervention period. Nonparametric longitudinal analyses revealed significant group-by-time interactions. After adjustment for multiplicity, significant group-by-time interactions were observed for perceived stress and reduced sense of accomplishment, a sub-variable of athlete burnout. Perceived stress significantly decreased in the face-to-face counseling group, whereas reduced sense of accomplishment significantly decreased in the AI chatbot counseling group. For supportiveness, …

Multihoming And Single-Homing Complementors' Responses To Intensified Between-Platform Competition: Evidence From The Youtube–Twitch Rivalry, Niloofar Abolfathi

Research Collection Lee Kong Chian School Of Business

Research Summary: This paper examines how heterogeneous YouTube content creators-specifically, single-homing and multihoming channels-respond to a sudden increase in the exposure of the rival platform, Twitch. Contrary to expectations, I find that multihoming channels reduce their content creation efforts and underperform relative to single-homers. To make sense of these surprising results, I develop a formal model that characterizes the strategic behavior of different types of complementors operating across two platforms with varying levels of user exposure. The model offers a plausible explanation for the observed empirical patterns, suggesting that intensified competition between platforms, as a consequence of their changing exposure, …

Testing Mean Stability Of Heteroskedastic Time Series, Violetta Dalla, Liudas Giraitis, Peter C. B. Phillips

Research Collection School Of Economics

Time series models are often fitted to the data without preliminary checks for stability of the mean and variance, conditions that may not hold in much economic and financial data, particularly over long periods. Ignoring such shifts may result in fitting models with spurious dynamics that lead to unsupported and controversial conclusions about time dependence, causality, and the effects of unanticipated shocks. In spite of what may seem as obvious differences between a time series of independent variates with changing variance and a stationary conditionally heteroskedastic (GARCH) process, such processes may be hard to distinguish in applied work using basic …

Between Artifice And Enlightenment: Queer Critique, Insecurity, And The Ai Large Language Model, Kevin S. Amidon Ph.D.

Modern Languages Faculty Publications

Over several decades, machine learning systems—often described with the double metaphor “artificial intelligence”—have become indispensable computational tools in the flow and mediation of economic and social capital. These systems can, on the surface, appear to deepen the dialectic of enlightenment identified by Horkheimer and Adorno by enabling ever greater domination over natural systems and human agency. They therefore generate widespread concern that computational advances endanger the security and autonomy of human subjects, especially in the sphere of production and exchange. Contemporary social theory offers conceptual tools that go beyond received categories of domination and autonomy, however, to provide a reanalysis …

Estimating The Average Treatment Effect In Randomized Controlled Trials With Incomplete Covariates, Elizabeth M. Pauley

Open Access Dissertations

Randomized controlled trials (RCTs) are commonly used to estimate average treatment effects (ATEs), with baseline covariates often included to improve precision and statistical power for detecting those effects. In applied settings, covariates can be incomplete, and some may moderate treatment effects, leading to heterogeneous treatment effects (HTE). Literature lacks clear direction regarding whether incomplete covariates should be included when estimating the ATE and how different missing data handling methods perform in such conditions. This study aimed to evaluate the performance of four missing data handling methods in RCTs via Monte Carlo simulations, namely listwise deletion (LD), inverse probability weighting (IPW), …

Protective Behavioral Strategies On Alcohol And Cannabis Co-Use Occasions, Sabrina Todaro

Open Access Dissertations

Simultaneous use of alcohol and cannabis, or co-use (i.e., the use of both substances so that effects overlap), is an increasingly significant public health concern among young adults between the ages of 18 and 25 in the U.S. (SAMHSA 2025; Terry-McElrath & Patrick, 2018). Protective behavioral strategies (PBS; i.e., tactics used to modify or limit substance use related harm; Pearson, 2013) have been robustly linked to fewer negative outcomes (e.g., lower use quantity, frequency, and consequences) for alcohol- and cannabis-only occasions (Bravo et al., 2016; Bravo et al., 2017; Bravo et al., 2019; Pearson, 2013; Pedersen et al., 2016; Pedersen …

An Experimental Investigation On The Influence Of Emotion On Craving And Alcohol Consumption Among Women, Melissa C. Rothstein

Open Access Dissertations

A burgeoning literature suggests that alcohol use, rates of binge drinking, rates of alcohol use disorder, and experiences of alcohol-related consequences are increasing among women in comparison to men (Adams et al., 2022; Baraona et al., 1991; Peltier et al., 2019; White, 2020). As such, alcohol use among women is a growing public health concern, but historically, most existing research, including interventions, has focused on men (Agabio et al., 2017; Holzhauer et al., 2020; Maxwell et al., 2022; Verplaetse et al., 2021; White, 2020). Although there is a large literature on the role of negative emotion in alcohol use (Austin …

The Colorado River: Searching For Solutions In The Face Of Uncertainty: Conference Summary, Emilia Endara, Douglas Kenney

Books, Reports, and Studies

The Colorado River is facing unprecedented change and uncertainty. Average annual flows continue to decline, and negotiations to craft post-2026 guidelines to manage the river have repeatedly bogged down in disagreements about delivery obligations, sharing shortages, and mandatory conservation. While some clarity may emerge in the coming months, the ability to sustain many existing municipal and agricultural water users is already being compromised. Meanwhile, there is growing recognition that a durable resolution must also address the water rights of sovereign Tribal Nations and better integrate environmental values into river management. All sovereigns, stakeholders, and sectors must work together now more …

Employment Preferences Of Favela Residents, Mayara Felix, Beatriz Marcoje, Ieda Matavelli, Maria Clara Rodrigues

Cowles Foundation Discussion Papers

We document employment preferences of workers at the margin of informality using open-ended questions and discrete choice experiments in Brazil’s largest favela complex. Stated preferences emphasize pay and tangible job benefits rather than meaning or purpose, while primary complaints center on poor management, customers, and inflexible schedules. Workers exhibit high valuations for all formal sector amenities on average—unemployment insurance, parental leave, and termination notice—as well as for learning opportunities, but lower for non-formal sector amenities such as shorter commutes. Valuations vary systematically by employment sector in ways consistent with sorting: formal workers value formal amenities most, the self-employed value them …

The First 1000 Days And Beyond: The Process Of Child Development, Orazio Attanasio

Cowles Foundation Discussion Papers

This paper reviews recent developments in the economics of human development, focusing on the early years of life as a critical period for shaping long-term outcomes. Early childhood development is inherently multidimensional: cognitive and socioemotional skills evolve dynamically and interact with health, nutrition, and environmental influences. Economists have contributed to this field by providing a conceptual unifying framework that highlights how key drivers of development reflect the choices of individuals operating under incentives and constraints. Within this framework, the paper emphasizes two central challenges: understanding the interactions among multiple dimensions of development and identifying causal links—particularly the effects of different …

Assessing Flood Resilience In West Virginia Communities: Integrating Physical, Institutional, Socioeconomic, And Environmental Dimensions, Anahita Mahmoudi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Flooding is one of the most frequent and damaging natural hazards in the United States, with impacts expected to intensify under changing climate conditions. In regions such as West Virginia, complex terrain, development patterns along river corridors, and socioeconomic disparities contribute to elevated flood risk. Traditional approaches to flood risk assessment often focus on single dimensions of vulnerability or rely on binary floodplain maps, which do not fully capture the spatial variability and multidimensional nature of flood resilience.

This dissertation develops an integrated, community-scale framework for assessing flood resilience in West Virginia by combining physical, environmental, institutional, and socioeconomic dimensions …

Assigning Library E-Books As Textbooks: An Examination Of Collection Development Policies And User Education Practices At Minority-Serving Institutions, Michelle Ehrenpreis

Publications and Research

Assigning library e-books as course textbooks can help to alleviate the financial burden of college for many students. Accordingly, libraries include e-books in their collection development policies and strive to educate users on the availability of these texts via the use of library research guides. Previous studies discuss library collection strategies and intentions to use e-books as textbooks, but do not discuss continuous or permanent plans. This study examined library policies at Hispanic Service Institutions (HSI’s) and Historically Black Colleges and Universities (HBCU’s) to evaluate how these libraries approach and document their acquisitions of library e-books. Research guides at the …

The Influence Of Scale In Modeling Social Vulnerability And Disaster Assistance, Sina Razzaghi Asl, Oronde Drakes, Eric Tate, Samuel Brody, Wesley Highfield, Kayode Atoba

Political Science & Geography Faculty Publications

Understanding how social vulnerability relates to disaster impacts is critical for addressing social equity, yet the role of spatial scale in this relationship is often overlooked. Most studies use aggregated data, risking ecological fallacy-misinterpreting individual outcomes from group-level data. This study examines how spatial scale influences the relationship between social vulnerability and federal disaster assistance after Hurricane Harvey. Using spatial econometric models at both household and census tract levels, we assessed the strength of key vulnerability indicators in explaining disaster assistance. Results show that disability, housing tenure, household size, and income predict assistance at the household level, but their influence …

Beyond Discrete Indicators: Modeling Intersectional Flood Vulnerability, Sina Razzaghi Asl, Eric Tate, Christopher T. Emrich, Md Asif Rahman, Kaeleb Royster

Political Science & Geography Faculty Publications

Social vulnerability to flooding is shaped by intersectional social marginalization, yet most quantitative assessments employ indicators of single populations. This study applies spatial machine learning to examine how the intersectional social vulnerability indicators of poverty-race, poverty-housing tenure, and race-housing tenure compare with traditional discrete indicators of single populations in predicting flood exposure in California. Using geographically weighted random forests and partial dependence plots, we model spatial heterogeneity and non-linear relationships between social vulnerability and exposure. We quantified flood exposure using a population-adjusted measure derived from building footprints and modeled 500-year fluvial and pluvial flood hazard. The results reveal distinct explanatory …

Africa As A Strategic Arena: How Great Power Rivalry Is Reshaping Security Governance, Chick Edmond

Political Science & Geography Faculty Publications

The rising importance of Africa as a key battleground in great power rivalry is an important shift in global politics that will have significant impacts on security governance in Africa. This article will explore the ways in which increased competition between the U.S., China and Russia will affect African states and regional organizations, and how economic dependency, regional security architecture and diplomatic strategy will influence the overall security environment in Africa. Using recent case studies and academic research, along with current policy analysis, it will analyze whether or not African countries and regional organizations will be able to mitigate potential …

Great Power Competition In Africa: Sustaining Openness Amidst Transnational Threats And Authoritarian Fragmentation, Chick Edmond

Political Science & Geography Faculty Publications

As the United States seeks to position itself in an increasingly competitive world, Africa has emerged as an increasingly key arena of great power competition where the United States, China, and Russia are competing to determine the nature of political norms, economic governance and security architecture on the continent.

The combination of growing transnational threats (such as terrorism, pandemics, climate-related instability, and digital vulnerability), and growing authoritarianism, has transformed the continent into a testbed for competing visions of international order. In light of this backdrop, this paper posits that the United States must pursue a strategy of sustained strategic openness …

Security Governance In Post-Colonial Africa And Implications On Democratic Institutions, Chick Edmond

Political Science & Geography Faculty Publications

This paper will evaluate how security governance contributes to both the development of democracy and the establishment of stable institutions within newly independent post-colonial states in Africa. Security governance is examined here as it relates to the long-term influence of colonial legacy, military presence, and the politicization of the security services. The authors have based their analysis of this issue on qualitative data gathered from Nigeria, Ghana, South Africa, Democratic Republic of Congo, and Kenya. The findings of the research suggest that unless security sectors are subject to civilian oversight and adhere to democratic principles, they tend to serve the …

Nuclear Deterrence And The Security Dilemma In A Complex Multipolar World, Chick Edmond

Political Science & Geography Faculty Publications

Objectives: The purpose of this research project is to examine how nuclear deterrence intersects with the concept of security dilemma, i.e., when a state takes an action intended to increase its own security it may inadvertently create a risk or threat to another state and contribute to increased levels of tension. Fourth, how nuclear and conventional systems are becoming increasingly interconnected, which will serve to potentially amplify risks associated with these systems.

Methods: Utilizing a qualitative analytical approach of documents such as national strategy documents, defense policy statements and historical records of crises dating from 1945-2025, the study identifies four …

Revisiting Dependency In The Twenty-First Century: A Critical Analysis Of Africa-China Relations, Chick Edmond

Political Science & Geography Faculty Publications

This research assesses the characteristics of today’s Africa–China relations using dependency theory, world systems theory, neocolonialism, and South-South cooperation, using comparisons between historical African dependence on European colonial powers and recent reliance on China in terms of trade, infrastructure, debt, and technology. This research identifies how contemporary cooperations either continue previous patterns of economic and political subordination or create a transformation of those relationships or provide a challenge to them. Using qualitative comparative historical analysis, along with specific case studies and secondary sources (academic journals, speeches, government publications, etc.), the research demonstrates that while Africa-China relations exhibit fewer structural features …

Autonomous Weapons And Strategic Stability, Chick Edmond

Political Science & Geography Faculty Publications

The increasing number of artificial intelligence (AI) elements within military systems has introduced new forms of security dilemmas related to speed, level of secrecy, and transfer of responsibility from humans to machines. This article addresses the question of whether or how AI enabled autonomous weapons can lead to greater levels of strategic instability. Three causal mechanisms were determined by this study to potentially create destabilizing effects due to the introduction of autonomy; the first mechanism is a reduction in time available for decision making. The second mechanism involves the creation of multiple pathways of escalation. The third mechanism is the …

Global Evidence On Scaling Nature-Based Solutions For Compound Hazards, Sina Razzaghi Asl, Anahita Azadgar

Political Science & Geography Faculty Publications

Nature-based solutions (NbS) are increasingly promoted for climate adaptation to compound hazards, but systematic evidence of their effectiveness is still scarce. We address this gap with a systematic review of 38 studies. Each study was sorted by what its measurement design can support, not by what its authors claim. This produced four groups. Direct studies attribute a measured hazard reduction to the intervention, proxy studies infer protection from ecosystem condition, prioritization studies map suitable locations without estimating performance, and qualitative studies describe effectiveness without measuring it. We detect trends in geographic distribution, hazard combinations, intervention types, methodological approaches, and strength …
