Understanding Resilience In Children In Out-Of-Home Care: Using Person-Centered Health Services Research, Hyeeun K. Shin

Theses and Dissertations--Health Services Research (HSR)

Adverse childhood experiences (ACEs), which refer to exposure to traumatic life events before age 18, and instability in caregiving experiences contribute to poor physical, mental, behavioral, and developmental health outcomes for both children and adults. Previous research shows that these experiences can have negative effects both in the short term and throughout a person’s life. However, children’s strengths, which are the internal and external assets that support their development, can help protect against the impact of ACEs. Effective parenting, positive social support, and self-regulation skills are essential factors that build resilience, helping individuals adapt to challenges that may affect their …

Suicide Stigma In A Cross-Cultural Context: Comparison Between Mexican And Mexican American Communities., Robin E. Gearing, Micki Washburn, Kathryne Brewer, Luis R. Torres-Hostos, Pedro Isnardo De La Cruz, Miao Yu, Natalia Giraldo-Santiago, Alberto Cabrera, Adelaido Garcia Andres

School of Social Work Faculty Publications

Suicide and suicide-related stigma are serious public health issues affecting Latine communities and often serve as a barrier to help-seeking Mexicans and Mexican Americans experiencing mental health concerns. Despite this, there are still gaps in our understanding of how suicide stigma specifically impacts Latines of Mexican heritage. While Mexicans and Mexican Americans share many familial, cultural, and religious values, their exposure to different societal norms may shape distinct perceptions of suicidal ideation and mental health. To better understand suicide-related stigma in these communities, we conducted a community-based survey with 248 Mexican Americans in Houston and 203 participants in Mexico City …

The Digital In The Library: Finding The Mutually Beneficial Synergy, James M. Donovan

Law Faculty Books and Chapters

With the value of access to digital resources abundantly demonstrated during the COVID-19 lockdown, enthusiasm for the format is reaching new heights. This chapter counsels restraint, rebutting the argument that skepticism concerning the wide adoption of digital materials into the library is due merely to nostalgia by anti-technologists for a now-bygone age. Despite their obvious usefulness in certain situations, patrons have not responded well when libraries propose to discard legacy print collections in favor of transient electronic formats.To explain this rejection, this chapter argues that libraries are built upon principles of collection development and organization of materials in order to …

Ai-Assisted Hybrid Ga–Pso Channel Allocation Under 3gpp Tr 38.901 Uma For Efficient 5g Radio Resource Management, Sharada Narsingrao Ohatkar

ASEAN Journal on Science and Technology for Development

The increased traffic and heterogeneity in the 5G/B5G network require efficient radio resource management (RRM). However, the existing methods, such as GA and PSO, have poor convergence speed and require proper initial conditions. Additionally, learning-based methods have high computational complexity. Hence, in this paper, a novel AI-assisted Hybrid Channel Allocation (AI–HCA) framework is proposed by using a support vector regression (SVR)-based predictive initialization method and GA-PSO optimization. Simulation results using the 3GPP UMa channel model show that the proposed method has a 28% reduction in call blocking probability (CBP), a 15-25% enhancement in spectral efficiency (SE), and a 18-25% enhancement …

Face2cam: A User-To-Webcam Distance Estimation Image Dataset, Yixuan Zhai, Arryn Robbins

Psychology Faculty Publications

Estimating the distance between a user and their device’s camera is important for tasks such as gaze-aware interaction, adaptive interface scaling, and accessibility tools. Specialized depth sensors are effective but rarely available in everyday computing devices; by contrast, webcams are ubiquitous yet lack native distance information. To advance accessible distance-aware computing, we present Face2Cam, an openly available dataset of webcam images annotated with user-to-camera distances. Thirty-six adults were photographed under controlled variation of head orientation, gaze direction, and illumination, yielding 3,240 labeled images spanning distances from 30–80 cm. As a baseline, we trained a convolutional neural network as a lightweight …

The Relationship Between Obsessive-Compulsive Disorder Symptoms And Reading Abilities And The Moderating Roles Of Parent-Teacher Involvement And Family Emotional Expressiveness, Tatiana Lombana Mims

University of the Pacific Theses and Dissertations

The present study focuses on how obsessive-compulsive disorder (OCD) symptoms influence reading abilities and whether parent-teacher relationships and family emotional expressiveness moderate that relationship. This study provides further knowledge on the relationship between mental health struggles and academic performance and possible risk/protective factors. Structural equation modeling through AMOS 31 was used to construct path analysis models to analyze the significance of OCD symptoms on reading abilities with parent-teacher involvement and family emotional expressiveness, both positive and negative, as moderators. The relationship between OCD symptoms and reading abilities indicated a consistent negative association though not statistically significant. Parent-teacher involvement did indicate …

Prosocial Ceos And Accounting Manipulation, Mei Feng, Weili Ge, Zhejia Ling, Wei Ting Loh

Research Collection School Of Accountancy

This paper examines the association between chief executive officers’ (CEOs’) prosocial tendency and their firms’ likelihood of accounting manipulation. We measure CEOs’ prosocial tendency based on their involvement with charitable organizations. We find that prosocial CEOs are less likely to engage in accounting manipulation, as proxied by material non-reliance restatements and SEC or DOJ enforcement actions. The effect is more pronounced when CEOs are involved with charities that directly aim to improve the welfare of others and when they face stronger incentives to misreport. These results continue to hold in analyses of changes in CEOs’ prosocial tendency around turnover events. …

Beyond Metrics: A Decade Of Building Critical Scholarship At The Interface Of Forest And Society, Muhammad Alif K. Sahide, Nurhady Sirimorok, Micah R. Fisher

Forest and Society

This editorial reflects on the first decade of Forest and Society by examining how scholarly journals can be understood beyond bibliometric indicators and ranking systems. While metrics remain influential in contemporary academic publishing, they offer only a partial account of how knowledge is produced, evaluated, and sustained. Drawing on a decade of editorial practice, the editorial foregrounds the intellectual, pedagogical, and institutional dimensions through which critical scholarship at the interface of forests and society has been cultivated. Beyond its role as a publication outlet, Forest and Society has evolved as part of a broader scholarly community, most notably through the …

Forest and Society

In the Pga K’nyau village of Ban Huay E Kang in the Chiang Mai province of northern Thailand, a newborn's umbilical cord is placed inside a bamboo container and hung from a tree. This is a sacred act of establishing a lifelong connection between each villager and the forest. The practice is known in the Pga K’nyau language as de paw thoo. This tradition has faced significant disruption from state-led conservation policies and the institutionalization of childbirth in state hospitals, which Ban Huay E Kang villagers contest through their revitalization of de paw thoo. Based on collaborative ethnographic research, …

The Unequal Partnership Behind Biodiversity Conservation Efforts In The Eastern Democratic Republic Of Congo, Alexandra Rasoamanana, Eliezer Majambu, Dominique Bikaba, Symphorien Ongolo, Emilie Dupuits

Forest and Society

The growing demand for inclusivity in conservation has led international conservation organisations (ICOs) to collaborate more with local conservation organisations (LCOs). This paper assesses such partnerships through a community-led initiative establishing a wildlife corridor between Maiko and Kahuzi-Biega National Parks. In this region, resource conflicts are often cited as a political justification for recurring conservation failures. However, this framing overlooks crucial questions about how fairness and sustainability in conservation are constructed in practice, particularly within contested forestlands where multiple groups claim legitimacy over ownership. We analyse the structural conditions that enable or constrain the formation of authentic partnerships. Such partnerships …

Systematic Approaches To Characterizing Vulnerabilities And Enhancing Robustness Of Text And Vision-Language Models, Poojitha Thota

Computer Science and Engineering Dissertations

The proliferation of artificial intelligence (AI) across critical domains, including news summarization, privacy-policy analysis, and medical decision support, has raised growing concerns about the security and robustness of these systems against adversarial manipulation. This dissertation investigates adversarial robustness in generative AI by addressing three key research goals: (1) characterizing adversarial vulnerabilities across generative models, (2) developing systematic defenses to improve the robustness of generative models, and (3) designing deployment-time safeguards for securing LLM interactions.

Towards the first goal, we characterize adversarial vulnerabilities across text-based and multimodal systems. In abstractive text summarization, we show that inference-time perturbations can exploit lead bias …

Designing An Approach To Developing Students' Symbol Sense For The Derivative In Calculus, Laura E. Weinstein

Theses, Dissertations and Culminating Projects

Students often struggle to connect the conceptual meaning of the derivative with the symbolic structures of Leibniz (dy/dx) notation. Although symbol sense has been described as the coordination of mathematical concepts, signs, and objects, little is known about how instruction can purposefully support students in developing symbol sense for the derivative. This study addresses this gap by designing and examining a learning approach aimed at helping students construct the relational structures underlying derivative notation. Using design research methodology, the study engaged intact algebra, precalculus and calculus classes in a suburban New Jersey high school across iterative cycles of design, implementation, …

Earth As Medium: Land Art And The Human Experience Of Connection To Nature, Charlotte Johnson-Watts

MA in Contemporary Art Dissertations

This dissertation examines how the Land Art of the 1960s and 1970s engaged the earth as both medium and site, foregrounding the ways in which artists constructed experiences of connection to the natural world. It focuses specifically on the practices of Michael Heizer, Robert Smithson and Richard Long, who each emerged as central figures during this period, turning to the earth itself as their primary material and rejecting traditional, commodifiable forms of art. For these artists, earthworks functioned not only as a critique of the social and political conditions of the time but also as an innovative way of re-engaging …

Urban Fieldnotes: Rematerialization, Ecological Handicraft, And Participatory Sustainability In Contemporary Art, Qihan Fu

MA in Contemporary Art Dissertations

This dissertation explores how the intertwined practices of rematerialisation and ecological handicraft can reorient contemporary art toward social, ecological, and ethical renewal. It argues that in the aftermath of Conceptual Art’s legacy of dematerialisation, where ideas eclipsed material engagement, art must rediscover its tactile, communal, and ecological intelligence to respond meaningfully to the crises of the Anthropocene. Drawing upon theorists including Lucy Lippard, Jane Bennett, Tim Ingold, and Glenn Adamson, this research proposes a triadic framework of rematerialization, ecological handcraft, and participatory sustainability that restores continuity between making, environment, and community.

The accompanying practice project, Urban Fieldnotes, situated in …

The Politics Of Protection: An Analysis Of Algerian State Communication Regarding Nationals In France (2026), Sophia Schmidt

International Studies Undergraduate Honors Theses

France and Algeria have long been connected, first by colonization and later through their shared histories and migratory flows. In the 1960s and 1970s, following Algerian independence, the Algerian government maintained connections with its immigrant community in France through collaboration with the French government on language and religious education and media programming. Today, as tensions rise between the two countries due to reciprocal resentment over the aftereffects of colonialism and recent international disagreements, it is necessary to examine how the Algerian government understands its own connection to and responsibility for the ever-growing population of Algerian immigrants in France. By examining …

Effect Of Mid-Range Ultraviolet Light On Avian Embryonic Development, Keelie Hughes

Biology Theses

While it is a known fact that specific environmental conditions must be met to ensure proper embryonic development, the impact of changes in this delicate balance is unclear. Ultraviolet (UV) light has a narrow range of effectiveness in mature tissue, where too little can hinder molecular signaling and too much can cause damage to genetic material. This study exposed in ovo chicken embryos in the preliminary stages of development to mid-range UV radiation to examine developing embryo and tissue morphology using anthropometric methods and comparing proliferative cells among embryos exposed to varying doses of UV light. Additionally, quantitative polymerase chain …

The trendline of the average height and curb weight of the top-selling vehicles in the United States has increased by 0.24 inches and 23.52 pounds per year since 1991. The average 2025 top-selling U.S. passenger vehicle is 7.5 …

Integrated Thermal, Energy, And Structural Performance Assessment Of A Novel In-Service Shallow Geothermal Bridge Deicing System, Alireza Fakhrabadi

Civil Engineering Dissertations

Understanding the performance of bridge deck deicing systems under winter weather conditions is important for improving transportation safety and reducing long-term deterioration of bridge infrastructure. Bridge decks are more vulnerable to icing than ground-supported pavements because they are exposed to ambient air, wind, and radiation from multiple directions, while they do not receive thermal support from the underlying soil. Conventional deicing methods, especially chloride-based salts, can reduce ice formation in the short term, but repeated application may accelerate reinforcement corrosion, concrete damage, and environmental concerns. Therefore, shallow geothermal energy has been considered as a sustainable alternative for bridge deck deicing …

Materials Science and Engineering Faculty Research & Creative Works

Understanding and controlling the grain structure of ZrB₂ is critical for optimizing its mechanical and thermal performance in high-temperature applications. Fully dense ZrB₂, densified by hot pressing at 2150˚C and 32 MPa, was analyzed in three dimensions using electron backscattered diffraction, electron and optical microscopy, and mechanical polishing serial sectioning. Grain size followed a gamma distribution, with extreme deviations observed only in the largest 0.1% of grains. Large grains exhibited plate-like morphologies, with the shortest-to-longest axis ratio converging to ∼0.4 as grain volume increased. This work revealed a crystallographically controlled growth mechanism orthogonal to [0001] that is …

The Effects Of Mold Flux Contamination On Oxide Scale Formation And Hydro-Descaling Efficiency During Steel Processing, Tochukwu Princewill Ojiako, Richard Osei, Mario Buchely, Haiming Wen, Simon Lekakh, Ronald O'Malley

Materials Science and Engineering Faculty Research & Creative Works

Oxide scale formation during thin-slab continuous casting has a complex structure, which is influenced by mold flux contamination, that modifies interfacial reactions during solidification, subsequent reheating, and descaling. While individual aspects of the oxidation behavior of carbon steel have been previously examined, the synergetic effects of mold flux contamination during continuous casting and subsequent reheating on scale modification and the efficiency of hydraulic descaling remain inadequately studied. This study quantitatively examines the effect of flux composition on oxide scale evolution, adhesion, and hydraulic removal in low-carbon steel under simulated industrial conditions. Slab samples with as-cast, cleaned, and flux-coated surfaces were …
