Identifying Landscape And Behavioral Drivers Of Human-Black Bear Conflict In New Hampshire, Shea O'Connor May 2026

Identifying Landscape And Behavioral Drivers Of Human-Black Bear Conflict In New Hampshire, Shea O'Connor

Master's Theses and Capstones

Abundant American black bear (Ursus americanus) populations and increasing human development in New Hampshire have led to a prevalence of human-bear conflict across the state. This conflict negatively impacts humans, bears, and even the surrounding environment as safety is put at risk and environmental roles are disrupted. This thesis aimed to address both the ecological and human dimensions of human-bear conflict by combining a quantitative spatial analysis with a qualitative thematic analysis. Chapter One examined anthropogenic and landscape factors influencing human-black bear conflict levels across New Hampshire. I utilized ordinal logistic regression to analyze how various ecologically relevant predictor variables …

The Baby And The Bathwater: Reproductive Abuse As Domestic Violence And Empowering Bodily Autonomy Through The Law, Kadhapriya Lindo May 2026

The Baby And The Bathwater: Reproductive Abuse As Domestic Violence And Empowering Bodily Autonomy Through The Law, Kadhapriya Lindo

University of Florida Journal of Law & Public Policy

Reproductive abuse—ranging from contraceptive sabotage and coerced pregnancy to coerced abortion and sexual violations such as stealthing—operates as a distinct and under-recognized form of domestic violence. By assessing medical, sociological, and legal research, it is clear how reproductive abuse holds a victim’s body and reproductive ability hostage, producing long-term physical, psychological, and familial harms. Existing criminal statutes, which focus on force-based sexual offenses, do not capture non-physical reproductive violations such as medication tampering or nonconsensual condom removal. Further, civil remedies, including tort claims and custody determinations, inadequately account for the harms of coerced conception and the long-term legal ties it …


Under The Influence: Why The Federal Government Should Implement A Tier System For Drunk Drivers, Maycie Bloom May 2026

Under The Influence: Why The Federal Government Should Implement A Tier System For Drunk Drivers, Maycie Bloom

University of Florida Journal of Law & Public Policy

Drunk driving persists as a serious problem in the United States, claiming thousands of lives every year. Although the drunk driving fatality rate decreased following advancements in federal drunk driving legislation during the 1990s, after decades of remaining unchanged, the drunk driving fatality rate has increased in recent years. The increase in drunk driving fatalities has been associated, in part, with an increase in drunk driving recidivism, a phenomenon that is closely linked to alcoholism and poses a serious problem for the community. Individuals who suffer from alcoholism often develop higher tolerances, which can lead to overconsumption and a diminished …


Undue Hardship In Student Loan Bankruptcy: A Circuit-By-Circuit Analysis Of Brunner, Rahaf Alrehaili May 2026

Undue Hardship In Student Loan Bankruptcy: A Circuit-By-Circuit Analysis Of Brunner, Rahaf Alrehaili

University of Florida Journal of Law & Public Policy

The judicial landscape of student loan discharge under the Brunner test reflects both commonalities and significant divergences across circuits. While courts generally adhere to a shared framework for assessing undue hardship, they remain divided on key issues, including whether retirement savings qualify as necessary expenses, the extent to which religious tithing is protected under the Religious Liberty and Charitable Donation Protection Act (RLCDPA), and whether a debtor’s refusal to enroll in an income-driven repayment (IDR) plan constitutes bad faith under Brunner’s third prong. Courts also disagree on whether IDR eligibility should be considered under the first or second prong …


Political Weapons Or Judicial Officers: How The United States Supreme Court's Increased Political Polarisation Highlights An Immediate Need For Reform, Marcello Jones May 2026

Political Weapons Or Judicial Officers: How The United States Supreme Court's Increased Political Polarisation Highlights An Immediate Need For Reform, Marcello Jones

University of Florida Journal of Law & Public Policy

The “politicization of justice” has become a most unwelcome stereotype for our nation’s highest court. While it is understandable that Justices must still judge, and so in a practical matter, leaving their political views at the door is not always possible. When society can accurately and consistently predict the Justices’ votes solely based on their political ideology, it is difficult to see past the view that the Justices are consistently manipulating the Constitution and the facts of the cases before them to serve their own political agenda. And when an Executive can be elected into office primarily based on the …


Religious Law Schools, Rankings, And Bias: Measuring The Rankings Penalty At Religious Law Schools, Michael Conklin May 2026

Religious Law Schools, Rankings, And Bias: Measuring The Rankings Penalty At Religious Law Schools, Michael Conklin

University of Florida Journal of Law & Public Policy

Law school rankings play a pivotal role in shaping legal education. However, these rankings have faced substantial criticism for their methodology, susceptibility to manipulation, and bias related to political ideology and race. This Article measures bias by applying a novel, quantitative analysis to disparities between the objective overall rankings and the subjective peer rankings among religiously affiliated law schools. The findings reveal that religiously affiliated law schools experience a 17.65 peer rankings penalty. Further analysis strengthens the evidence of bias by showing a heightened penalty among more devoutly religious law schools. A longitudinal analysis finds that this trend is rapidly …

Is Hipaa Still Protecting Your Medical Data? An Analysis Of Deidentification As A Security Measure In The Age Of Ai., Jessica Novak May 2026

Is Hipaa Still Protecting Your Medical Data? An Analysis Of Deidentification As A Security Measure In The Age Of Ai., Jessica Novak

The University of New Hampshire Law Review

Artificial Intelligence is rapidly altering the landscape of many industries, and for some, faster than the law can necessarily keep up, leaving those industries unprotected from AI-related concerns. For the healthcare industry in particular, the integration of AI presents large-scale data privacy concerns. The current law protecting patient data privacy, the Health Insurance Portability and Accountability Act (“HIPAA”), is potentially already outdated and inadequate; concerns about HIPAA’s efficacy have long-existed and AI’s integration has only solidified this concern. It is potentially inadequate because of a provision within the law itself-deidentification. HIPAA allows healthcare providers to remove identifying information from a …


"Smart" Cities And Due Care With Emerging Technologies, Anthony J. Luppino May 2026

"Smart" Cities And Due Care With Emerging Technologies, Anthony J. Luppino

The University of New Hampshire Law Review

The rapid development of increasingly powerful technologies presents new opportunities to produce public benefits, as exemplified by the “Smart Cities” movement. Conversely, emerging technologies pose significant threats to public safety and individual rights, as evidenced by high-profile cyberattacks and other technology-related incidents, and in warnings issued by some Artificial Intelligence experts. This article examines the responsibilities of local governments in the United States as users of technology and as regulators of uses by other actors—arguing that they have a duty of care, traceable to the Preamble to the U.S. Constitution, to act diligently in that dual role whether or not …


Revocation Reconsidered: Probation Advocacy Through A Litigation Lens, Shira Diner May 2026

Revocation Reconsidered: Probation Advocacy Through A Litigation Lens, Shira Diner

The University of New Hampshire Law Review

Being found in violation of probation has dire consequences. The person found in violation can be imprisoned, upending them from their job, family, and community. Unlike incarceration after a criminal trial, a sentence after a violation of probation is not the result of a legal process characterized by robust due process protections. It is also often not the result of a forceful and thorough defense. It is instead the consequence of a hearing where lawyers with the fixed mindset of an inevitable finding of a violation don’t engage in the same preparation that they would if it was a trial. …


Exploration Of Expressive Prosody During Dyadic Conversation In Adults With Dementia, Kara Marie Sabanski May 2026

Exploration Of Expressive Prosody During Dyadic Conversation In Adults With Dementia, Kara Marie Sabanski

Undergraduate Honors Thesis Collection

Dementia is associated with progressive cognitive and communicative impairments that can contribute to social withdrawal and reduced quality of life. Although prior research has explored musical interventions and the use of prosodic features for early diagnosis, little is known about how expressive prosody is linked to engagement and communicative state during dyadic conversation in individuals with dementia. The present study examines different speech characteristics present in expressive prosody during conversation and explores whether these characteristics are associated with differences in conversational and behavioral engagement. Acoustic measures of pitch and speaking rate were analyzed during conversational interactions. Results indicated that prosodic …

Ambient Air Pollution In New Mexico: Nurse Practitioner Awareness, Mckenzie Hemmes, Grayson Kemp May 2026

Ambient Air Pollution In New Mexico: Nurse Practitioner Awareness, Mckenzie Hemmes, Grayson Kemp

Doctor of Nursing Practice Scholarly Projects

Ambient air pollution is a significant public health concern in New Mexico and contributes to respiratory disease, cardiovascular illness, and adverse pregnancy outcomes (Dominski et al., 2021; Di et al., 2022). Despite well-established evidence linking environmental exposures to health outcomes, environmental exposure screening is not routinely incorporated into clinical practice. The purpose of this Doctor of Nursing Practice (DNP) project was to improve environmental health literacy (EHL) among advanced practice registered nurses (APRNs) in New Mexico and to increase their intention to integrate ambient air pollution exposure screening and mitigation counseling into routine clinical practice. A virtual educational intervention guided …

Creating Healthy Work Environments (CHWE)

Background: Nurse burnout is a global health priority that has been compounded by Coronavirus 2019 (COVID-19). Organizational theory states that nurse burnout is directly impacted by operant mechanisms (nurse characteristics, nurse specialization) and hospital-wide models. The purpose of this study is to determine the relationship between hospital wide models (evidence-based care, team-based care, discharge planning, care coordination), operant mechanisms (nurse characteristics and specialization), and outcomes (nurse burnout) before and after COVID-19.

Design: A cross-sectional design was applied, using secondary data analysis.

Methods: A secondary data analysis using the 2018 and 2022 NSSRN data set was used to …


A Rare Convergence: Malignant Thymoma With Pericardial Invasion In A Brca2 Mutation Carrier With A Synchronous Breast Mass, Mahmoud Yacout, Mohammad Chisti May 2026

A Rare Convergence: Malignant Thymoma With Pericardial Invasion In A Brca2 Mutation Carrier With A Synchronous Breast Mass, Mahmoud Yacout, Mohammad Chisti

Conference Presentation Abstracts

Introduction Thymomas are rare epithelial tumors of the anterior mediastinum, accounting for < 1% of adult malignancies, with an estimated annual incidence of approximately 0.15 cases per 100,000 persons. Although often indolent, thymomas are malignant by definition and may invade locally, recur, and, less commonly, disseminate. They are classically associated with autoimmune conditions, most notably myasthenia gravis, yet their relationship with hereditary cancer syndromes remains poorly defined. Germline BRCA2 mutations are well established in the pathogenesis of breast, ovarian, pancreatic, prostate, and other malignancies through impaired homologous recombination DNA repair. However, an association between BRCA2 mutations and thymic epithelial tumors has rarely been reported. We describe an unusual case of invasive malignant thymoma with pericardial invasion in a BRCA2 mutation carrier, discovered concurrently with a synchronous FDG-avid breast mass suspicious for malignancy. Case Presentation An 85-year-old man with a history of CAD, hypertension, GERD, and prior radical prostatectomy presented with several months of unintentional weight loss and chronic diarrhea. During evaluation for recurrent appendicitis, imaging incidentally revealed a large anterior mediastinal mass measuring up to 7.9 cm with irregular margins. FDG-PET demonstrated moderate metabolic activity within the mass (SUVmax 3.8). CT-guided biopsy revealed a thymic epithelial neoplasm consistent with thymoma. There was no clinical evidence of myasthenia gravis. He subsequently underwent partial sternotomy with thymectomy. Pathology demonstrated a 6-cm type B2 thymoma with direct pericardial invasion, positive surgical margins (R1), and no regional lymph node involvement (pN0), consistent with pT2 stage III disease by the Masaoka–Koga system. Given high-risk features, adjuvant radiation therapy was initiated, with planned surveillance using PET imaging and circulating tumor DNA monitoring. Concurrent PET imaging identified a palpable FDG-avid right breast mass. Genetic testing revealed a pathogenic germline BRCA2 mutation. The breast lesion is currently undergoing diagnostic biopsy and surgical evaluation. Discussion Thymomas are malignant neoplasms with a predilection for local invasion. Type B2 thymomas carry a higher risk of recurrence, particularly in the presence of pericardial invasion or incomplete resection. Complete surgical excision remains the cornerstone of management, while postoperative radiotherapy is recommended in invasive or R1 disease to reduce locoregional recurrence. The coexistence of invasive thymoma and a germline BRCA2 mutation is exceedingly rare and raises questions regarding shared oncogenic mechanisms. While thymic epithelial tumors are not classically associated with BRCA mutations, DNA repair defects may contribute to tumorigenesis in rare malignancies. The presence of a synchronous FDG-avid breast mass in a male BRCA2 carrier further underscores the importance of comprehensive oncologic and genetic evaluation and highlights the need for multidisciplinary management in complex hereditary cancer presentations. Conclusion We report a rare case of malignant type B2 thymoma with pericardial invasion in a BRCA2 mutation carrier, identified alongside a synchronous breast mass suspicious for malignancy. This case highlights the potential intersection between thymic epithelial tumors and hereditary cancer syndromes, reinforces the importance of genetic evaluation in patients with multiple malignancies, and underscores the need for long‑term multidisciplinary surveillance. Further investigation is warranted to elucidate any causal relationship between BRCA‑mediated DNA repair dysfunction and thymoma development.

Dignity And The Free Press, Erin C. Carroll May 2026

Dignity And The Free Press, Erin C. Carroll

Georgetown Law Faculty Publications and Other Works

As American institutions wither and die, those who believe in their importance must reflect and rebuild. One institution worthy of sustained attention is the free press. Divorced from government by design, the press can benefit from efforts to reinvigorate and reinvent it in ways that institutions more directly under the federal government’s thumb cannot. To best undertake these efforts, we need a richer understanding of why a free press is vital. Articulating the values that underlie the need for this institution is necessary not only to build the most robust free press, but also to best exercise our freedoms as …


Popular Accountability And State Constitutional Law, Jonathan L. Marshfield May 2026

Popular Accountability And State Constitutional Law, Jonathan L. Marshfield

Vanderbilt Law Review

American constitutionalism operates against the backdrop of democratic processes, but the federal Constitution approaches democracy differently than state constitutions. The federal Constitution is built to fend off rash majoritarianism through checks and balances and siphoning accountability into a few highly mediated representative bottlenecks—elections for President and Congress. State constitutional structure is different. Through processes like judicial elections, the citizen initiative, referendum, recall, popular conventions, and elections for various executive offices, state constitutions reflect skepticism of wholesale representative democracy and trust in extant electoral majorities to participate in governance. This Article argues that state constitutional law should better account for this …


Effects Of Vitamin E Deficiency On Anxiety-Like Behavior In Zebrafish With Distinct Stress Coping Styles, Areem Zahid May 2026

Effects Of Vitamin E Deficiency On Anxiety-Like Behavior In Zebrafish With Distinct Stress Coping Styles, Areem Zahid

Theses/Capstones/Creative Projects

Stress and anxiety disorders affect millions worldwide and represent a significant public health burden. Individual differences in stress coping style and antioxidant regulation contribute to variability in stress responsiveness and anxiety-related behaviors. Oxidative imbalance has been implicated in the neurobiology of anxiety, but its interaction with inherent stress coping phenotypes remains unclear. This study examined whether long-term dietary vitamin E deficiency alters anxiety-like behaviors in zebrafish selectively bred for proactive and reactive stress coping styles. Adult zebrafish were maintained on either a vitamin E–sufficient or vitamin E–deficient diet for five months, followed by behavioral assessment using the novel tank diving …

Insights Into Androgen Receptor Allosteric Modulation By P,P'-Dichlorodiphenyldichloroethylene Binding At The Binding Function-3 Site And Site-Specific Binding Function-3 Mutations, Emanuel Aggeo Flores May 2026

Insights Into Androgen Receptor Allosteric Modulation By P,P'-Dichlorodiphenyldichloroethylene Binding At The Binding Function-3 Site And Site-Specific Binding Function-3 Mutations, Emanuel Aggeo Flores

Theses and Dissertations

One of DDT’s metabolites, p,p’-dichlorodiphenyldichloroethylene (DDE), has been classified as an endocrine disrupting chemical (EDC) due to its ability to interfere with hormone signaling by binding to nuclear receptors (NR) such as the androgen receptor (AR).

Structurally, the AR contains a ligand-binding domain (LBD) where endogenous steroids bind. Furthermore, the LBD contains a surface binding site known as binding function-3 (BF-3), which studies suggest exerts an allosteric effect on bound DHT when small, hydrophobic molecules bind.

Here, we present a study that examines how specific BF-3 site mutations and DDE binding affect steroid stability within the LBP utilizing computational methods. …


Using Behavioral Monitoring To Assess Activity Patterns And Welfare Indicators In Captive Black Howler Monkeys (Alouatta Caraya), Ramiro Gomez Iii May 2026

Using Behavioral Monitoring To Assess Activity Patterns And Welfare Indicators In Captive Black Howler Monkeys (Alouatta Caraya), Ramiro Gomez Iii

Theses and Dissertations

This study examined activity patterns and potential welfare indicators in captive black howler monkeys (Alouatta caraya) using behavioral monitoring techniques. A monogamous pair housed indoors at Gladys Porter Zoo was observed using focal sampling methods, and a species specific ethogram was developed to systematically record behavior. A total of 1,750 minutes of data were collected over one year. Observed behaviors were categorized into five groups: affiliative, agonistic, stationary, locomotion, and stereotypic behaviors. Activity budgets were calculated to determine the proportion of time allocated to each behavioral category. Results indicated that affiliative behaviors, particularly physical contact, dominated the activity budget, while …


Exploring The Role Of Video Games In Civil Engineering Education And K-12 Stem Engagement, Jillian S. Codron May 2026

Exploring The Role Of Video Games In Civil Engineering Education And K-12 Stem Engagement, Jillian S. Codron

Architectural Engineering

Civil engineering education has traditionally emphasized a linear progression from theory to application, with foundational concepts introduced in lecture before being reinforced through laboratory or design experiences. While effective for advanced learners, this approach can limit early engagement for K–12 students who may struggle to connect abstract principles to realworld engineering practice. This project examines the use of video games as interactive, feedback-driven environments for introducing civil engineering concepts and practices to younger learners in more exploratory and accessible ways.

The study pursues four primary objectives: evaluating the educational affordances of selected video games; examining how gaming experiences have influenced …


Manipulation Or Monetization?: The Rise Of Stock Buybacks And Their Effects On Firm Valuation And Investment, Thomas H. Serrano May 2026

Manipulation Or Monetization?: The Rise Of Stock Buybacks And Their Effects On Firm Valuation And Investment, Thomas H. Serrano

Economics Undergraduate Honors Theses

Abstract:

This thesis uses basic econometrics to examine the relationship between stock buybacks, firm valuation, and investment among publicly traded firms from 2000-2024. Using firm-level data pulled from Compustat North America and a fixed-effect multivariate regression, it evaluates whether buybacks are associated with higher valuation and stronger productive investment as defined in the paper. The results show that buybacks are positively associated with firm valuation the first year that they occur, but the relationship disappears when they are lagged for a year. Furthermore, the analysis does not find strong statistical evidence that repurchases are associated with changes in investment, or …

F.L.A.I.R. -- A Flow-Level Autoencoder For Intrusion Recognition, Joseph P. Dumond May 2026

F.L.A.I.R. -- A Flow-Level Autoencoder For Intrusion Recognition, Joseph P. Dumond

Electrical Engineering and Computer Science Undergraduate Honors Theses

Industrial Internet of Things (IIoT) networks underpin critical infrastructure worldwide, yet securing them remains an open challenge. Traditional intrusion detection systems require labeled attack data for training, a resource that is rarely available in real industrial deployments. They also fail against novel threats, a model trained on known attacks has no basis for detecting anything outside its training set. This thesis presents a Flow-Level Autoencoder for Intrusion Recognition, or FLAIR, a fully unsupervised deep learning system for network intrusion detection in IIoT environments. FLAIR is built on a Gated Recurrent Unit (GRU) autoencoder trained exclusively on normal network traffic. Rather …
