Toward Equitable Micromobility: Lessons From Austin E-Scooter Sharing Program, Shunhua Bai, Junfeng Jiao

Research Collection College of Integrative Studies

This study revealed the inequitable societal impacts of E-scooters on disadvantaged populations. The study conducted a population distribution analysis to compare the use opportunities and space intrusion burdens of E-scooter sharing on four vulnerable population groups in Austin, Texas. Nearly all minority population experienced fewer E-scooter use opportunities. Ten percent of the minority population waited for a disproportionately longer time before a disturbance could be resolved. Ten percent of the low-income population were in a disadvantaged position in high opportunities and moderate burdens. Twenty percent of the physically disabled population faced more moderate-level burdens. The result did not show significant …

Analyzing Racial Disparities In The United States Homeownership: A Socio-Demographic Study Using Machine Learning, Arya Farahi, Junfeng Jiao

Research Collection College of Integrative Studies

While increasing homeownership has been a focal point for policymakers in the United States, the distribution of access to homeownership opportunities across all families within the country has not been equitable. The complex relation between social factors and economic conditions has significantly shaped the journey toward homeownership. Of particular concern is the persistent disparity in homeownership rates among Black households in the United States. Effectively addressing these disparities within urban communities necessitates comprehensive policy interventions and social initiatives. However, the success of such endeavors hinges upon a comprehensive grasp of the underlying causes of these inequalities. Drawing upon machine learning …

Consistent Seasonal Hydrography From Moorings At Northwest Greenland Glacier Fronts, Marie J. Zahn, Kristin L. Laidre, Malene Simon, Kathleen M. Stafford, Michael Wood, Josh K. Willis, Elizabeth M. Phillips, Ian Fenty

Faculty Research, Scholarly, and Creative Activity

Greenland's marine-terminating glaciers connect the ice sheet to the ocean and provide a critical boundary where heat, freshwater, and nutrient exchanges take place. Buoyant freshwater runoff from inland ice sheet melt is discharged at the base of marine-terminating glaciers, forming vigorous upwelling plumes. It is understood that subglacial plumes modify waters near glacier fronts and increase submarine glacier melt by entraining warm ambient waters at depth. However, ocean observations along Greenland's coastal margins remain biased toward summer months which limits accurate estimation of ocean forcing on glacier retreat and acceleration. Here, we fill a key observational gap in northwest Greenland …

Detection And Measurement Of Bacterial Contaminants In Stored River Water Consumed In Ekpoma, Imokhai T. Tenebe, Eunice O. Babatunde, Nkpa M. Ogarekpe, Joshua Emakhu, Egbe Etu Etu, Onome C. Edo, Maxwell Omeje, Nsikak U. Benson

Faculty Research, Scholarly, and Creative Activity

This study was conducted in Ekpoma, a town dependent on rainwater and river water from nearby areas because of a lack of groundwater sources, and the physicochemical and bacteriological (heterotrophic plate count [HPC], total coliform count [TCC], and fecal coliform count [FCC]) properties of 123 stored river water samples grouped into five collection districts (EK1 to EK5). The results were compared with regulatory standards and previous regional studies to identify water quality trends. While most physicochemical properties met drinking water standards, 74% of samples had pH values > 8.5. Twenty-seven samples were fit for drinking, with EK4 having the highest number …

The Intellectual Roots Of Hindutva: Influences From Early German Romantics And Mahatma Gandhi, Johannes Scheuer

Dissertations, Theses, and Capstone Projects

The economic and political ascent under the leadership of the Bharatiya Janata Party (BJP) and Narendra Modi has not only increased interest in Indian politics but also highlighted the dominance of Hindu nationalism (Hindutva) as a political ideology in contemporary India. Many scholars and journalists have drawn parallels between European fascist movements of the past and reactionary movements in today's political landscape to understand the rise and dominance of Hindutva. However, this paper takes a different approach by tracing the intellectual roots of Hindutva through the political philosophy of the Early German Romantics, particularly Johann Gottfried Herder, and the philosophy …

Building Networks, Producing Spaces For Play: Local Geographies And National Organizing In The History Of Adventure Playgrounds In The United States, 1949-1999, Reilly B. Wilson

Dissertations, Theses, and Capstone Projects

This dissertation provides an historical analysis of repurposed material adventure playgrounds in the United States between 1949 and 1999. Three microhistories of adventure playgrounds (The Yard, in Minneapolis, M.N., and several playgrounds in New York City, N.Y., and Houston, T.X.) are framed against the wider socio-economic changes that shaped more than thirty-five adventure playgrounds in the United States over the period of study. By focusing on the relationships mobilized by adventure playground advocates at different scales and across different points of view, and how these networks shaped the local production of spaces for play, this dissertation's method underlines the importance …

Building Black Manhattan: Architecture, Art, And The Politics Of Respectability, 1857–1914, Jessica Larson

Dissertations, Theses, and Capstone Projects

“Building Black Manhattan” is the first study to examine the architectural contributions of Black women reformers to the urban development of New York City between the Civil War and the Great Migration. Through the construction of charitable and reform institutions throughout Manhattan, they articulated a strategy of racial uplift through deliberate spatial construction.

As reform work was one of the very few arenas in the nineteenth and early twentieth centuries in which women had a significant public voice, the buildings constructed to facilitate reformers’ work encoded the social, racial, and gendered demands of women into their designs. These institutions included …

The Film, The Stadium And The Jail: The Post-Industrial Transformation Of Downtown Durham, Seth Rose

Dissertations, Theses, and Capstone Projects

By the late 1980s, Durham, North Carolina’s downtown-based industrial economy had been replaced by a powerful knowledge economy in the city’s peripheries. Downtown Durham’s vast array of tobacco and textiles manufacturing buildings stood empty, along with most of its commercial spaces, offices and sidewalks. This thesis argues that the local development of two major public works, a baseball stadium (the Durham Bulls Athletic Park) and a jail (the Durham County Detention Center), conceived and constructed on similar timelines in close physical proximity, was indicative of how—and for whom—city and county officials envisioned a revitalized downtown. The first chapter examines the …

Bodies That Traverse: Colonial Fantasies Of Oriental Incorporations In Late Medieval England, Soojung Choe

Dissertations, Theses, and Capstone Projects

“Bodies that Traverse: Colonial Fantasies of Oriental Incorporations in Late Medieval England” shows how a picture of a proto-colonialist England arises from popular romances of the period, particularly those featuring the Crusades and the “Orient,” or the fictional Near East, as its central narrative locus. While the historical Crusades to the Holy Land mainly took place between the eleventh and twelfth centuries, English fictional writing on the Crusades flourished in the “post-crusade” period of 1200–1450. My project argues that the Orient in these writings, especially popular vernacular romances, serves as a colonial ‘contact zone,’ a fetishized site for England to …

Future Land, Futures Lost: Planning The Crisis On The Louisiana Coast, Sheehan Moore

Dissertations, Theses, and Capstone Projects

South Louisiana is rapidly losing coastal land to the combined forces of subsidence, sea-level rise, and worsening storms, accelerated by the effects of flood control engineering and extractive industrial development. With erosion threatening homes and industry alike, the state has marshaled a response on a massive economic and geographic scale: its Coastal Master Plan recommends $50 billion in river sediment diversions, barrier island restoration, and other projects over fifty years. This dissertation is about the emergence of Louisiana’s coast as a place from this knot of human and environmental relations, as an object for governance and a container for political …

Living Color: Aesthetic Surfaces And Political Life In Brazil, Samuel E. Novacich

Dissertations, Theses, and Capstone Projects

This dissertation is about the manipulation of appearances – of both the human body and the built environment – in Rio de Janeiro, Brazil. Focused on Afro-aesthetic makeup and tanning practices as well as urban renewal projects, this ethnographic study reveals how the making over of both the skin and the urban landscape shape social inequalities and contribute to productions of race, gender, and national belonging. While some of the aesthetic technologies examined herein may be characterized as “bottom up” – or as the self-fashioning tactics of marginalized Afro-Brazilians – others constitute “top down” infrastructural interventions led by the state …

Play In The Undercommons: The Transformative Power Of Fugitive Practice In A Multiracial, International Teacher Inquiry Collective, Kushya Sugarman

Dissertations, Theses, and Capstone Projects

Though scholars have begun to position youth’s fugitivity, refusal, and disengagement as logical responses to hostile environments, and as part of a larger legacy of Black speculative planning and action, most teachers do not. Elementary teachers, especially in urban contexts, notoriously struggle with “classroom management” and teachers across contexts cite behavior challenges, such as “disruptive” behavior, as the number one challenge facing our schools. In fact, up to 50% of novice teachers leave the profession in the first five years due to students’ behaviors. This dissertation interrogates the common trope of the wayward student who must be controlled. I consider …

Just Transitions: Critical Exploration Of Environmental Policy And Decision-Making Through The Lens Of Lived Stories, Mariya Marinova

Dissertations, Theses, and Capstone Projects

This research explores perspectives on just transition, what transitional policies and practices are already set in motion, the conditions necessary to achieve it, and how this knowledge can inform environmental policy. Focusing on West Virginia, it employs qualitative methodology with open-ended interviews and develops life sketches of transitions to demonstrate how deeply intertwined just transition is with the lives of the people in places marked by extractive industries. Combining guiding principles from environmental and landscape justice, energy justice, feminist energy systems framework, and place attachment theory, the findings reveal that just transitions need to be transformative, focusing on understanding how …

Race, Rebellion, And Counterinsurgency: California's Supermax Prisons, Stephen Jones

Dissertations, Theses, and Capstone Projects

This dissertation project concerns the geographies of counterinsurgency in California’s super-maximum-security prisons. I argue that these facilities – the first of which opened in the mid-1980s, and which were more repressive and isolating than any of California’s existing prisons – were explicitly developed in response to powerful organizing by people in prison. As early as 1973, corrections administrators and prison officers argued that dangerous prison gangs, organized along racial and geographical lines, were behind prisoner militancy, and advocated for expansive security measures including indefinite confinement in supermax prisons. I demonstrate, however, that officers and administrators deliberately promoted conflict, attempting to …

Supporting Social Equity Through Informal Spaces On An Urban Campus, Eve B. Klein

Dissertations, Theses, and Capstone Projects

This dissertation focuses on applying research to design in the setting of higher education. Specifically, it explores the informal spaces outside the classroom at a predominantly Black college in an urban setting. The existing structural challenges facing college students are many, including issues related to financial resources, mental health/wellness, family responsibilities, psychosocial identity formation, and structural racism. These challenges were compounded by the events of the spring of 2020, when a heightened awareness of anti-Black racism, combined with the hardships of COVID-19, brought college campuses to a close and masses of people to the streets to protest the unjust killings …

Original Vs. Simplified Miranda Rights: The Impact On Miranda Rights Comprehension And Subsequent Waiver Decisions, Sydney Baker

Dissertations, Theses, and Capstone Projects

Youths’ developmental immaturity negatively impacts their ability to meaningfully understand and appreciate their Miranda rights, raising questions about the validity of their waiver decisions. Moreover, most Miranda warnings are long, written at advanced reading levels, and contain complex sentence structure and vocabulary, which further hinders comprehension. In response, several jurisdictions have begun to use developmentally informed Miranda warnings for youth. However, research has yet to determine whether this improves youths’ ability to make informed Miranda waiver decisions. As such, the current research study explored whether simplified Miranda warnings increased youths’ comprehension of their rights, whether Miranda comprehension was related to …

Essays In Health Economics And Applied Econometrics: Assessing Recreational Marijuana Laws, Dragos Ailoae

Dissertations, Theses, and Capstone Projects

This dissertation explores the diffusion and impacts of state recreational marijuana laws (RML). Chapter 1 examines factors driving state adoption and spread of RML, finding that states with citizen ballot initiatives, expansive legislative capacities, and higher fiscal stress are more likely to enact RML. Ideological proximity, rather than geography, drives policy diffusion, with learning from early adopters likely serving as a key mechanism in the process. Chapter 2 assesses first-order effects of RML on marijuana consumption and drug policing using various econometric methods. Results suggest amplification bias in difference-in-differences point estimates due to an endogenous policy variable. This has economic …

Explainable analytics models are transparent models in which the primary factors and weights that lead to a prediction can be explained. Typical AI models are non-transparent or opaque models, …

Quantifying Delay Propagation In Airline Networks, Liyu Dou, Jakub Kastl, John Lazarev

Research Collection School Of Economics

We develop a framework for quantifying delay propagation in airline networks by integrating structural modeling and machine learning methods to estimate causal effects. Using a comprehensive dataset on actual delays and a model-selection algorithm (elastic net), we estimate a weighted directed graph of delay propagation for each major airline in the United States and establish conditions under which the propagation coefficients are causal. These estimates enable a decomposition of airline performance into "luck" and "ability." Our findings indicate that luck accounts for approximately 38% of the performance difference between Delta and American Airlines in our data. Additionally, we leverage these …

Utilization Of Geospatial Distribution In The Measurement Of Study Cohort Representativeness., Keith Feldman, Natalie J. Kane, Stacey Daniels-Young, Bruce Reed, Jessica Welch, Lauren Fitzpatrick, Mark A. Hoffman, Andrea Bradley-Ewing, Elin Grundberg

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVE: The ability to apply results from a study to a broader population remains a primary objective in translational science. Distinct from intrinsic elements of scientific rigor, the extrinsic concept of generalization requires there be alignment between a study cohort and population in which results are expected to be applied. Widespread efforts have been made to quantify representativeness of study cohorts. These techniques, however, often consider the study and target cohorts as monolithic collections that can be directly compared. Overlooking known impacts to health from socio-demographic and environmental factors tied to individual's geographical location, and potentially obfuscating misalignment in underrepresented …

Beneficial Effects Of Lactobacillus Plantarum On Growth Performance, Immune Status, Antioxidant Function And Intestinal Microbiota In Broilers, Xiao Xiao, Tiantian Cui, Songke Qin, Tao Wang, Jinsong Liu, Lihan Sa, Yanping Wu, Yifan Zhong, Caimei Yang

Faculty, Staff and Student Publications

Lactobacillus plantarum (L. plantarum) has been globally regarded as antibiotic alternative in animal farming in the past few years. However, the potential function of L. plantarum in broilers has not been systemically explored. In this study, a total of 560 one-day-old yellow-feathered broilers were randomly divided into 3 groups, fed with basal diet and drank with L. plantarum HJZW08 (LP) at the concentration of 0 (CON), 1000 × 10^5 (LP1000), and 2000 × 10^5 CFU/L (LP2000) for 70 d. Results showed that the body weight (BW), average daily …

An Analysis Of Suspected Microplastics In The Muscle And Gastrointestinal Tissues Of Fish From Sarasota Bay, Fl: Exposure And Implications For Apex Predators And Seafood Consumers, Eric Conger, Miranda Dziobak, Elizabeth J Berens Mccabe, Tita Curtin, Ayushi Gaur, Randall S Wells, John E Weinstein, Leslie B Hart

Faculty, Staff and Student Publications

Microplastics have been found in the gastrointestinal (GI) fluid of bottlenose dolphins (Tursiops truncatus), inhabiting Sarasota Bay, FL, suggesting exposure by ingestion, possibly via contaminated fish. To better understand the potential for trophic transfer, muscle and GI tissues from 11 species of dolphin prey fish collected from Sarasota Bay were screened for microplastics (particles <5 mm diameter). Suspected microplastics were found in 82% of muscle samples (n=89), and 97% of GI samples (n=86). Particle abundance and shapes varied by species (p<0.05) and foraging habit (omnivore vs. carnivore, p<0.05). Pinfish (Lagodon rhomboides) had the highest particle abundance for both tissue types (muscle: 0.38 …

Reclaiming Healing Spaces: A Phenomenological Study On The Transformative Power Of Outdoor Therapy From The Lived Experiences Of Black Clinicians Working With Black Clients, Lynn Murphy

Dissertations

This phenomenological study involved assessing the experiences of Black therapists who engaged Black clients in outdoor therapeutic contexts. The study was founded on the existing literature that shows the quality of the therapeutic relationship is pivotal for client retention and the Western standards that have historically favored treatment within indoor environments. To contextualize this research, a comprehensive literature review was commenced, covering topics such as the decolonization of therapy, the historical and present-day relationship between Blacks and the outdoors in the United States, sedentary lifestyles, the psychological benefits of time spent in nature, various types of outdoor therapy, and the …

Embodied Energy Injustice And The Political Ecology Of Solar Power, Dustin Mulvaney

Faculty Research, Scholarly, and Creative Activity

Solar energy is poised to become a major source of electricity around the world. As deployment rises to terawatts levels, these industries will drive demand for specific materials, natural resources, labor, and lands with solar energy resources reconfiguring socio-ecological relations. Global change from the development of solar power commodity chains includes increased demand for minerals and metals, new places for metallurgy and smelting, shifting workforce flows, occupational safety challenges from extractive industries to semiconductor manufacturing fabs. These new geographies of production could result in increased emissions and effluents from specialty chemical industries, conservation and agricultural land use change, and questions …

Does It Take A Village? The Impact Of Lgbtq+ Community And Geographic Location On Associations Among Parenting Stress, Parent Mental Health, And Child Adjustment, Kevin A. Mcaweeney, Rachel H. Farr

Psychology Faculty Publications

While LGBTQ+-parented families share many similarities with their cis-het parent counterparts, they still experience unique factors exclusive to them. One such factor is access to the LGBTQ+ community. Utilizing a diverse sample of LGBTQ+ parents with adolescents in the U.S., primarily living in Southern and Midwest states, we examined the potential moderating impact of a parent’s sense of LGBTQ+ community on the relationship between parenting stress, parent mental health, and child adjustment. Regression analyses demonstrated a series of positive associations between LGBTQ+ parent stress, parent mental health concerns, and child adjustment issues. However, sense of community failed to moderate these …

Temperature affects the timing of the transformation of amorphous silica (opal-A) into crystalline (opal-CT) exponentially. Thus, in hot subseafloor environments opal-A is expected to convert into opal-CT at relatively shallow burial depths, where in situ temperatures do not exceed ∼56 °C, as it has been previously observed at various deep-sea sites and in onshore rock outcrops as well as assessed during lab experiments. The response of biosilica (biogenic opal-A) diagenesis to steep geothermal gradients (∼224–529 °C/km) at extremely high sedimentation rates (∼1 m/kyr) was examined in cores from off-axis boreholes drilled by the International Ocean Discovery Program (IODP) Expedition 385 …

Black, Indigenous, And People Of Color's Experiences Of Discrimination In Psychoanalytic Professional Organizations In The Usa: Results Of A Thematic Analysis Of Interview Data, Carter Carter, Rory Crath, Christine Tronnier, Harshita Bhargava, Alison Espinosa-Setchko, Julia Galeota, Q. Garcia-Geary, Tara Lasheen, Diana Sencherey, Rachel Steindler

School for Social Work: Faculty Publications

This article reviews the results of a qualitative study of Black, indigenous, and people of color (BIPOC)'s experiences of discrimination in psychoanalytic professional organizations (PPOs) in the USA. The authors used thematic analysis to analyze the transcripts of semi-structured interviews with n = 10 self-identified BIPOC with prior experience in PPOs, including psychoanalytically-oriented graduate programs, psychoanalytic institutes and other training programs, and professional membership organizations across the United States. A key finding is that a significant majority of interviewees (n = 9) reported experiencing discrimination in these organizations, per their own definitions of the term “discrimination,” and described these experiences …

The Psychometric Properties Of The Swahili Version Of The Primary Care Post Traumatic Stress Disorder Screen For Dsm-5 Among Adults In Kenya, Patrick Nzivo Mwangala, Joseph Newton Guni, Paul Mwangi, Millicent Makandi, Anita Kerubo, Rachel Odhiambo, Amina Abubakar

Institute for Educational Development, East Africa

Background: The psychometric properties of the Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) are undocumented in Kenya and sub-Saharan Africa (SSA) at large. This study aimed to evaluate the psychometric properties of the Swahili version of the tool, S-PC-PTSD-5, in a community sample of adults 18 years and older drawn from Nairobi, Mombasa and Kwale counties in Kenya.

Methods: Analysis of cross-sectional data from 1431 adults from the community was conducted, examining the reliability, factorial structure, measurement invariance, and convergent and divergent validity of the interviewer-administered S-PC-PTSD-5.

Results: Out of 1431 adults who completed the S-PC-PTSD-5, 666 (46.5%) reported experiencing …

Disappearing Immigrant Shadows: A New Analytical Framework And Typology For Second-Generation Chinese American Ethnic Engagement, Annie Wang

Dissertations, Theses, and Capstone Projects

This capstone challenges the predominant narrative that upwardly mobile, second-generation individuals prefer to socially distance themselves from working-class, first-generation co-ethnics, a concept referred to here as ethnic distancing. It argues that this narrative fails to capture the second generation’s affinity and capacity for ethnic engagement, which includes desired and actual participation in ethnic-based activities ranging from casual consumption to more meaningful volunteerism, activism, and community building with co-ethnics of diverse socioeconomic backgrounds. Drawing on 32 interviews with second-generation Chinese Americans aged 18-35, I argue that we can better understand ethnic engagement in New York City’s Manhattan Chinatown by …
