Echocardiography Evaluation Of Aortic Dissection: A Case Study, Alyssa Garvey

Bachelor of Science in Diagnostic Ultrasound Projects

Aortic dissection is a deadly condition where the layers of the aorta tear apart, often causing sharp pain and a lack of blood flow to vital organs. A 55-year-old male presented with worsening shortness of breath, dyspnea on exertion, and peripheral edema. A transthoracic echocardiogram and computed tomography angiogram were performed and uncovered an ascending aortic aneurysm and a combined Stanford A and B aortic dissection. The patient was rushed into emergency surgery where a Bio-Bentall Procedure was performed. Due to lack of insurance, the patient put off receiving medical aid causing his condition to progress for the worse. Improved …

Testing The Influence Of Increased Predation On The Evolution Of Morphological Coloration Plasticity In Trinidadian Killifish (Anablepsoides Hartii), Alyssa M. Laux

Biology Theses

The ability to camouflage is a widespread trait in both vertebrates and invertebrates that enhances survival in risky environments. The ability of organisms to respond to shifts in environmental conditions and change color is a conspicuous example of camouflage. Such coloration plasticity can occur rapidly (seconds to minutes) versus longer periods of time (days to months). There are numerous examples of physiological coloration plasticity (short-term) and morphological coloration plasticity (long-term). Yet, there are few tests of the conditions that drive the evolution of physiological vs. morphological coloration plasticity. In this study we use Trinidadian killifish (Anablepsoides hartii) as …

Ebola In The Drc: A Different Problem Compounded By Violence, David Brett-Major

Journal Articles: Epidemiology

A Public Health Emergency of International Concern (PHEIC) has been declared in the Democratic Republic of Congo (DRC) due to Ebola disease from Bundibugyo virus. Non-health-focused factors should be fundamental to how DRC and its partners respond to and recover from the current emergency. Filovirus emergencies are violent in every sense-the disease experience of patients and their caregivers, the tumult in impacted communities, sometimes the physical manifestations of frustration against healthcare services, the fits and starts of concerted response, and the milieu of conflict in which this emergency occurred. Yet, interpersonal and organized violence may contribute to frequency of health …

The Role Of Academic Vocabulary Instruction In Supporting Secondary English Learners' Science Proficiency, Chue Seng Her

All Electronic Theses and Dissertations

This literature review examines the extent to which academic vocabulary instruction influences secondary English learners’ (ELs’) science proficiency. Science learning requires students to interpret complex texts, engage in academic discourse, and construct evidence-based explanations using discipline-specific language, which may present challenges for ELs. This review provides an overview of research on language demands in science and instructional approaches that support vocabulary development. Findings indicate that academic vocabulary plays a critical role in students’ ability to comprehend scientific content, participate in discourse, and communicate reasoning effectively. Instructional approaches such as explicit vocabulary instruction, scaffolding, discourse-based strategies, reciprocal teaching, cognitive strategy instruction, …

Economic Exchange And Relational Work In Doubled-Up Households, Hope Harvey

Sociology Faculty Publications

Doubling up, or sharing a home, is an increasingly common way that families make ends meet. Drawing on over 170 in-depth interviews with 60 parents, I ask how doubled-up household members understand and contest their economic relationships. I show that the success of intra-household economic exchange depends not only on the amounts exchanged, but also the shared meanings behind these exchanges. Given the lack of institutionalized expectations guiding doubled-up household relationships, household members draw on competing norms, framing the household as either a solidarity unit or a series of independent nuclear family units. Although disagreement over economic relationships is common, …

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 …

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 …

Mechanical Property Evaluation Of Paper Die Materials In Explosive Forming, Higa Yoshikazu, Kadena Hisashi, Shimojima Ken, Iyama Hirofumi

ASEAN Journal on Science and Technology for Development

This study investigates the feasibility of using paper materials as substitutes for molds in explosive forming by systematically evaluating their mechanical properties. Tensile tests were conducted on three paper types differing in thickness and internal fiber structure, using a custom-designed gripping tool. Specimens were prepared in multiple orientations to account for anisotropic behavior. Results indicate that coated paper, exhibiting the highest specific tensile strength and energy absorption per unit basis weight, is the most suitable for formability. In contrast, thick paper, characterized by the lowest specific tensile energy absorption, offers the best dimensional accuracy. Anisotropy was observed in matte and …

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 …

Umbilical Cord Connections: Ban Huay E Kang Women's Ecological Knowledge Transmission And Mobilization, Areerat Worawongwasu, Yuting Zhou, Phyo Su San

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, …

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, …

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 Rise In Height And Curb Weight Of The Top-Selling Vehicles In The United States From 1991 - 2025: Implications For Engineering Design And Vulnerable Road Users, Samuel L. Steinman-Friedman

Civil Engineering Theses

Road fatalities are higher in the United States than in other high-income regions. In 2024, 39,254 people died on roads in the United States compared to 19,940 in the European Union. These two regions have comparable exposure metrics, such as population size, roadway network length, and fatalities per mile traveled. Light trucks dominate the U.S. market, whereas hatchbacks are prevalent in Europe. 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 …

Extreme Points And Majorization, Andreas Kleiner, Benny Moldovanu, Philipp Strack

Cowles Foundation Discussion Papers

Many seemingly different economic problems share a common mathematical structure: they involve the maximization of a functional over sets of monotonic functions that are either majorized by, or majorize, a given function. This paper presents new, simpler proofs for the main characterization results of the extreme points of sets defined by monotonicity and majorization constraints obtained by Kleiner, Moldovanu, and Strack (2021). It demonstrates how these characterizations can be applied to a broad range of economic applications, including auction and information design, contest design, optimal delegation, optimal stopping, and decision problems under risk. The paper concludes with an overview of …

The Non-Punishment Principle And Restorative Justice, Rachel J. Wechsler

Faculty Publications

The non-punishment principle is a legal norm that has increasingly gained legitimacy over the past quarter-century within international, regional, and domestic law on human trafficking. At its core, this principle opposes the punishment of human trafficking victims for unlawful conduct they engage in as a consequence of their trafficking victimization. Little is known about the presence and operation of the non-punishment principle within U.S. law. This Article fills this gap as the first to comprehensively map and analyze the principle’s instantiation across state and federal law.

From this new map, three key themes emerge. First, the non-punishment principle has a …

Protecting Those Who Protect Us: A Blueprint For Mandatory Mental Wellness Standards For First Responders, Joy Hutchinson

Faculty & Staff Scholarship

First responders, including firefighters, law enforcement officers, emergency medical technicians (EMTs), dispatchers/telecommunicators, and corrections officers, serve as the backbone of public safety in the United States. Their work requires rapid decision-making, repeated exposure to traumatic events, and sustained emotional regulation in high-stakes environments (Hoell et al., 2023; Vig et al., 2020). Despite their critical roles, mental health support across these professions remains inconsistent, optional, and largely reactive rather than preventative, with many systems relying on self-referral only after crisis onset (Burke, 2021; Johnston et al., 2025).

Between 2021 and 2025, U.S.-based research has documented alarming levels of burnout, depression, anxiety, …

Experiments In Graph Structure And Knowledge Graph Embeddings, Antrea Christou, Cogan Shimizu

Computer Science and Engineering Faculty Publications

Knowledge graphs (KGs) are an established paradigm for integrating heterogeneous data and representing knowledge. As such, there are many different methodologies for producing KGs, which span notions of expressivity, and are tailored for different use-cases and domains. Now, as neurosymbolic methods rise in prominence, it is important to understand how the development of KGs according to these methodologies impact downstream tasks, such as link prediction using KG embeddings (KGEs). In this article, we examine how various perturbations of graph structures impact downstream tasks. These perturbations are sourced from how various methodologies (or design practices) would impact the model, starting with …
