Drawing And The Pursuit Of Progress In The Late 19th-Century Dominican Republic, Felix V. Rodriguez Suero

Faculty Publications – Art

Eugenio Maria de Hostos, with the support of late 19th-century Dominican liberals, spearheaded the transition from scholastic education to an education grounded on scientific principles and liberal ideals. Through the discussion of four fundamental principles for drawing instruction in Hostos’s educational project, I examine why teaching young people drawing skills was central to his anticolonial political project. Drawing from decolonial and critical frameworks, I analyze the connection between art classes in schools and the political struggles to democratize and modernize Dominican society. I argue that, despite seemingly good intentions, the influence of Western philosophy and 19th-century scientific rationalism led Hostos …

Long-Term Evaluation Of The Energy Consumption Of 100 Energy-Efficient Buildings In Austria, Thomas Roßkopf-Nachbaur, Günter Lang, Martin Ploß, Markus Lang, Andreas Peter, Tobias Hatt, Diana Ürge-Vorsatz, Souran Chatterjee, Luisa F. Cabeza

School of Geography, Earth and Environmental Sciences

In 2019, buildings greenhouse gas (GHG) emissions accounted for 21 % of global emissions, therefore regions such as Europe have strong policies to decrease such emissions. The literature shows different examples simulating energy refurbishment of buildings or districts where an important GHG reduction can be achieved, but there is a clear gap on real measurements of exemplary buildings. This paper shows an assessment of more than 100 energy-efficient buildings in Austria, showing that this GHG emissions reduction is really possible. The paper evaluates residential and non-residential buildings, where the energy consumption was 50 % below the consumption of typical multi-apartment …

The Effects Of Environmental Complexity On Brain Development And Personality Expression In Western Hognose Snakes, Gokulan Nagabaskaran

Theses and Dissertations (Comprehensive)

There is growing interest in snake cognition, personality, and welfare as more snakes are kept as pets, yet little research has been conducted. The effects of enrichment and environmental factors have been well documented in other taxa, and recent evidence suggests that snakes may benefit in similar ways. This dissertation investigated the impact of environmental and social enrichment on personality expression, personality stability, and brain development. Western hognose snakes (Heterodon nasicus) were used as the model species, as they are a popular choice in the pet trade. This allows the research to be readily translatable to husbandry practices of many …

The Politics Of Survival: South-South Migration, Urban Informality, Governance, And The Food Security Nexus In Nairobi, Kenya, Zack Ahmed

Theses and Dissertations (Comprehensive)

This dissertation contributes to the scholarship on South-South migration by integrating food security into the analysis of urban governance and migrant livelihoods in Sub-Saharan Africa. While migration and development have been widely examined, their connection to food systems remains underexplored, particularly in urban settings where informality, displacement, and transnational mobility converge. The research addresses this gap by investigating how Somali migrants and refugees in Nairobi’s Eastleigh navigate food insecurity within overlapping systems of governance, inequality, and transnational exchange. It explores three dimensions: the structural and socio-economic determinants of migrant household food insecurity, the impact of the COVID-19 pandemic as a …

Impacts Of Burn Severity On The Hydro-Physical, Chemical And Thermal Properties Of Sub-Arctic Peat, Joshua B. Meyer Mr

Theses and Dissertations (Comprehensive)

Under current climate change, summer season in the boreal regions of Canada is becoming increasingly warmer and drier. This shift is driving increases in the frequency and intensity of naturally occurring wildfires and allowing access to areas not normally susceptible to fire such as wetlands. In peatland areas, these increasingly large fires can create complex burn scars, which contain a wide variety of different burn severities across different landcover types. This variety calls for a greater understanding of how varying fire intensity affects the hydro physical, chemical, and thermal characteristics of boreal peat. This study aims to deepen that understanding …

The Association Between Maternal-Fetal Medicine Physician Density And Pregnancy Outcomes, Tetsuya Kawakita, Rula Atwani, Misa Hayasaka, Lindsay Robbins, George Saade

Department of Obstetrics & Gynecology Faculty Publications

Objective

We sought to examine the association between maternal-fetal medicine (MFM) physician density and adverse pregnancy outcomes at the state level.

Study Design

This was a cross-sectional analysis of publicly available, state-level data from 2018 to 2021, including Natality, Multiple Cause-of-Death, and Fetal Death databases. The number of active MFM physicians per year was obtained for each state from the American Medical Association Masterfile. The primary exposure was the density of MFM per state, categorized into three groups: (1) low density (< 30 MFM physicians per 100,000 live births), (2) moderate density (30-59 MFM physicians per 100,000 live births), and (3) high density (≥60 MFM physicians per 100,000 live births). Our primary outcome was maternal mortality during pregnancy and up to 42 days postdelivery. Our secondary outcomes were pregnancy-related mortality up to 365 days postdelivery and stillbirth. We calculated adjusted incident rate ratios (aIRR) and average marginal effect (AME) with 95% confidence intervals (95% CI) using multivariable negative binomial mixed effects regression models.

Results

Overall, there were 14,792,743 live births, 3,440 maternal mortalities, 4,980 pregnancy-related mortalities, and 90,848 stillbirths included. The …

The Impact Of Student Achievement On Economic Growth: A Pisa-Based Analysis Of Gdp Per Capita, Emma Rose Nasr

Undergraduate Theses and Capstone Projects

This study investigates the extent to which international student achievement, measured through PISA assessments in mathematics, reading, and science, explains cross-country differences in economic development. Using an unbalanced panel data set combining PISA results from 2015, 2018, and 2022 with macroeconomic indicators from the World Development Indicators, I estimate multiple regression models, including pooled OLS, country and time fixed effects, and subsample analyses for developed and developing countries. Results from the pooled model indicate strong positive associations between PISA scores and GDP per capita, consistent with human capital theory. However, these relationships diminish under fixed effects specifications, suggesting that cross-country …

Comparing Us Medicare Coverage Options As A Contributing Mechanism To Sticking Or Switching To An Insurance Plan, Lisa M. Grabert, Brian J. Miller, Kathryn L. Wagner

College of Nursing Faculty Research and Publications

Background

In 2025, the US Medicare program is expected to spend over $1.1 trillion taxpayer dollars. A growing trend in the US Medicare program is more beneficiaries electing a private insurer, referred to as Medicare Advantage (MA), to manage their care. Since 2023, a slight majority of Medicare beneficiaries have elected to enroll in MA, yet little is understood about the mechanisms that drive beneficiaries toward their choices.

Methods

Our objective was to examine the association between comparing coverage options and ‘switching’ or ‘sticking’ with Fee-for-Service (FFS) Medicare or Medicare Advantage (MA). We conducted a panel study, using data from …

Seasonal And Geographic Patterns Of Gastroschisis In Canada: Protective Effect Of Periconceptional Sunlight Exposure, Shiliang Liu, Shin Jie Yong, Dunjin Chen, Gavin C. Hughes, Claude L. Hughes

Department of Medicine Faculty Publications

Background: Gastroschisis is a right-sided, full-thickness defect with extra-amnionic herniation of abdominal contents directly into the amniotic cavity. The causes of gastroschisis remain obscure. We hypothesized that limited periconceptional sunlight exposure might lead to insufficient vitamin D during fetal development and play a role in gastroschisis etiology.

Methods: We conducted a population-based cohort study of infants conceived in Canada between April 2006 and March 2020. We used winter months (i.e., November and December) and northern geographic latitudes as indicators of insufficient sunlight exposure, while summer months (July and August) and southern geographic latitudes were considered as reference. We examined the …

Lack Of Disparities In Postoperative Care After Ileocecal Resection In Patients With Crohn's Disease At Tertiary Inflammatory Bowel Diseases Centers, Shannon Coombs, Molly Powell, Kemmian Johnson, Jessica Hu, Mollie Webb, Philip Mcdaniel, Parakkal Deepak, Edward L Barnes

2020-Current year OA Pubs

BACKGROUND: Prior studies suggest that longer drive time (DT) to specialists and higher area deprivation index (ADI) are linked to worse outcomes in inflammatory bowel disease (IBD), but their impact on postileocolic resection (ICR) care in patients with Crohn's disease (CD) is not well defined.

OBJECTIVES: We aimed to evaluate disparities in post-ICR care based on DT and ADI.

METHODS: Spatial analysis was performed with ArcGIS Pro to geocode patient and medical facility addresses with StreetMap Premium locators. High DT was defined as >60 min from the center. Data were analyzed using basic statistics and multivariate logistic regression.

DESIGN: A …

Analytical And Empirical Data-Driven Risk-Governance Design Across The Different Phases: Creating Informed Policy Adjustments For The Transportation Project Lifecycle, Mariam A. Elazhary

Doctoral Dissertations

"Transportation infrastructure is a critical foundation for economic productivity, yet agencies still face challenges in translating the expanding transportation datasets into defensible, phase-specific risk-governance tools. This dissertation addresses this gap by developing analytical and empirical, data-driven approaches to support risk governance across the transportation project lifecycle. Module 1 uses a panel model with bid-letting data to examine how out-of-state contractor participation affects pre-award competition and to derive entry-governance rules. Module 2 analyzes nonfatal injury data through iterative multiple linear regression and fatality data through association-rule change mining to identify multi-factor safety-risk configurations and develop adaptive safety-governance provisions. Module 3 develops …

Sources Of Tensions In Ai Adoption For Organ Procurement Organizations, Amaneh Babaee

Masters Theses

"Although medical AI systems have promise, the healthcare system has not fully integrated them for improved organizational operations. Studies have been conducted to identify root causes for this hesitancy without targeting a specific domain in healthcare. This generalization can be enhanced for the nuanced or domain-specific factors that offer practical insights to organizations leader. In this thesis, I focus on the factors and sources of tensions in AI adoption in transplant system, which is highly regulated but encourages innovation. Applying the Extended Technology, Organization, Environment (TOE) framework, 10 interviews were conducted at Organ Procurement Organizations (OPOs).

Dropouts And Refusers: Clinicians’ Insights And Initiatives Into Reducing Treatment Attrition Amongst Young People Who Sexually Offend, James L. Finney, Natalie Gately, Suzanne Rock, Jocelyn Jones

Research outputs 2022 to 2026

Sexual offending by young people causes significant harm to victims, families and communities. Treatment engagement and completion are therefore important for reducing future harm; however, young people who drop out of, or refuse to engage in, treatment present a unique challenge for clinicians and justice systems. Drawing on Bronfenbrenner’s (1979) ecological systems theory, this study explored clinicians’ perspectives on the barriers to treatment engagement and completion for young people who have sexually offended in the Australian context. Semi-structured interviews were conducted with clinicians who provided or facilitated treatment for young people who had sexually offended (N = 22). Two major …

Precarity On The Move: The Relative Economic Precarity Of Mobile Youth Moving To Australia, Lara Mckenzie, Anita Harris, Loretta Baldassar

Research outputs 2022 to 2026

Analyses of precarity often focus on how insecure employment, careers, finances, and geographies influence people’s lives for the worse, with young people understood as especially precarious in their economic stability and transitions to adulthood. This article analyses accounts of precarity amongst middling transnationally mobile youth, drawing from 24 semi-structured interviews incoming to Australia, and longitudinal survey data. We show that experiences of economic precarity are impacted by their access to work, government support, ability to access or sustain visas, and access to support from family and partners. By drawing on migration scholars’ observations that transnational mobility can be privileged and …

Tall Orders: A Comparison Of Resident Food Behaviours By Dwelling Type And Apartment Characteristics In Australia, Joelie Mandzufas, Siobhan Hickling, Kevin Murray, Sarah Foster, Gina S.A. Trapp

Research outputs 2022 to 2026

To accommodate population growth, Australian cities are becoming denser, with more Australians living in apartments. However, there is little understanding of whether this shift towards apartment living raises any potential short- and long-term implications for dietary health. Using an Australian nationally representative household survey, this cross-sectional study compared meal-purchasing frequency and fruit and vegetable intake by dwelling type, apartment block height, and number of bedrooms in the apartment. Adjusted mean differences were derived from linear regressions, adjusting for socio-demographic characteristics. Apartment residents purchased 0.72 more meals out each week than house residents (p < 0.001, 95% CI [0.599,0.831]) and consumed 0.10 fewer daily serves of vegetables (p = 0.002, 95% CI [0.038,0.163]). Among apartment residents, those in high-rise blocks purchased 0.80 more meals out each week than low-rise residents (p = 0.012, 95% CI [0.250,1.348]), and residents of one-bedroom or studio apartments ate 0.25 fewer serves of fruit per day than residents in apartments with at least three bedrooms (p = 0.003, 95% CI [0.038,0.163]). These findings provide important evidence to inform policy and targeted interventions that promote healthy food behaviours in apartment-living populations.

The Networked City: City Climate Change Networks And U.S. Climate Governance, Caroline G. Cox

American University Law Review

City climate change networks complicate common narratives about the local role in environmental and climate change governance in the United States. These networks—organizations with three or more member cities or representative city staff that share information and resources—are crucial actors in supporting the increasing interest in local climate change mitigation. Building upon prior scholarship addressing mayor-led networks and municipal collaborations, this Article considers how city climate networks challenge notions of local parochialism and rebut some critiques of local climate action. The Article also evaluates the growing importance of these networks in light of changes in federal climate policy, including the …

Beyond Marriage: Challenging Marital Prerequisites In State Adoption Laws Through A Constitutional And Child-Centered Lens, Alisha Glass

American University Law Review

Many state adoption laws restrict joint adoptions to married couples, thus excluding unmarried partners who share loving and committed relationships with the children they seek to adopt. These marital prerequisites reflect society’s outdated preference for the nuclear family while conflicting with adoption law’s commitment to the best interests of the child. Nonmarital families experience unequal legal protections based on marital status and geographic location. Building on the Kentucky Supreme Court’s decision in G.G. v. Cabinet for Health & Family Services, this Comment examines the limits of resolving these disparities through statutory interpretation and identifies the constitutional questions that remain …

Half-Armenian, Fully Diasporic: Navigating Memory, Trauma, And Identity In Marcella Polain’S The Edge Of The World, Sebnem Nazli Karali

Research outputs 2022 to 2026

This work of creative nonfiction employs a hybrid creative-critical methodology that combines autobiographical narrative and interview-based research within the framework of memory studies. Drawing on Marianne Hirsch’s concept of postmemory, the article examines how knowledge of the Armenian Catastrophe is transmitted, refracted, and contested across generations in the Armenian diaspora in Australia. It situates The Edge of the World, Marcella Polain’s semi-autobiographical novel, within broader traditions of diasporic and postmemory writing, arguing for its significance as a literary meditation on historical rupture and inherited trauma. Interweaving Karali’s personal diasporic narrative with a close reading of Polain’s novel and her in-depth …

Migration Literacy And Commercial Intermediaries: The Debt Financed Labour Migrations Of Chinese Working-Class Tradesmen In Boomtime Australia, Catriona Turnbull

Research outputs 2022 to 2026

This paper explores how constrained informational capital makes migrants dependent upon commercial intermediaries to facilitate their migration. It proposes migration literacy as a critical dimension of mobility capital and as a way to articulate the dependencies engendered through low information capital in relation to the regulatory regimes of the immigration state. These ideas are illustrated with reference to a cohort of working-class labour migrants to Australia whose experiences are shaped by their low migration literacy. Trade skilled migrants from China paid high fees to chains of brokers to secure sponsored employment in Australian workshops. Their low migration literacy, the result …
