The Caspian Sea, the Earth's largest inland water body, faces water level decline, drawing comparisons to the collapse of the Aral Sea. Unlike the Aral Sea, the relative roles of climatic variability, hydrological changes, and anthropogenic pressures on the Caspian Sea remain poorly understood. Here, we integrate satellite observations, in situ hydrological records and reanalysis data to examine recent drivers of the Caspian water loss. We show that total river inflow to the Caspian Sea has declined significantly, primarily due to reduced discharge from the Volga River. At the same time, precipitation over the basin has remained broadly stable, while …

Expanding Transmobilities: Understanding Genderdiverse And Transgender Travel Behavior Through An Art-Informed Methodology, Nicholas Michael Puczkowskyj

Dissertations and Theses

Transgender and genderdiverse people face discrimination and harassment in public when making trips in Portland, OR. People who identify as genderdiverse or transgender create unique travel behavior due to the influence of their internalized and expressed gender identity and through interactions in public. This dissertation examines how gender identity influences the travel behavior of genderdiverse and transgender people and how these experiences influence their subjective wellbeing when making trips in Portland, Oregon. Traditional one-on-one interviews were conducted in conjunction with allowing the interviewees to produce art as a non-verbal form of expression and communication of their experiences making trips in …

Center for Cybersecurity

This study analyzes cyberattack trends targeting non-profit organizations using longitudinal data collected over a three-year period within the Non-Profit Cybersecurity Incident Repository (NPCIR). Developed through a National Security Agency Center of Academic Excellence in Cyber Defense (NSA CAE-CD) designated center, the NPCIR applies an open-source intelligence (OSINT) methodology to systematically document cybersecurity incidents affecting the global non-profit sector. This study examines attack types, threat actor characteristics, sectoral distribution, and cybersecurity impacts using the Confidentiality–Integrity–Availability (CIA) triad framework. The results indicate that availability-related incidents, particularly ransomware and distributed denial-of-service (DDoS) attacks, constitute the most prevalent threats, while confidentiality breaches remain highly …

Implementation Of A Mixed Precision Iterative Solver On An Amd Apu, Saeyeon Kim, Henrik Evers

Computer Science and Engineering Senior Theses

Solving systems of linear equations is a core operation in high-performance computing and many scientific and engineering applications. One of the most widely used direct methods for solving such systems is LU factorization. Mixed-precision methods accelerate these solvers by using low-precision LU factorization with iterative refinement, improving performance and energy efficiency while preserving high numerical accuracy. AMD Accelerated Processing Units (APUs), which integrate CPU and NPU resources, provide an opportunity to explore this approach on emerging heterogeneous architectures. However, effective NPU utilization remains challenging due to workload partitioning, buffer management, data-movement overhead, and software tooling limitations.

This project implements a …

Privately Negotiated Withdrawals: How Shareholders Can Shape A Company's Carbon Emissions Reduction, Gabriella M. Chioffi

Duke Environmental Law & Policy Forum

Governed by the U.S. Securities and Exchange Commission's Rule 14a-8, shareholder proposals are a fundamental and longstanding mechanism that investors use to express their opinions and preferences on how a corporation is operating. Over the last decade, there has been a marked shift in the subject matter of the proposals that shareholders are submitting, as concerns relating to the environment have become an increasingly key issue. However, shareholder support for these climate-related proposals reached its highest point in 2021 and has declined slightly in subsequent years. The conditions that made shareholder proposals a successful tool in 2021 have since changed, …

The system combines hardware and software components, including a dual-camera setup and a custom visualization pipeline, to produce both qualitative and quantitative outputs. Users are able to …

A Protestant Response To The Pope’S Magnifica Humanitas On Ai, Derek Schuurman

University Faculty Publications and Creative Works

Pope Leo XIV released his first papal encyclical, Magnifica Humanitas, on May 25, a roughly 42,000-word document outlining a Catholic response to recent developments in AI. I had been eagerly anticipating this encyclical and spent much of the release day poring over the text. While there have been other Christian efforts to release statements about AI, this is the first comprehensive statement from the Catholic Church. What follows is a summary of the document, followed by my own response.

Colonial To Neoliberal Governmentality In Monument Governance: Shifting Positionalities Of The Monument Adjacent Communities In India, Ujal Kumar Mookherjee, Shreyasi Bhattacharya

Socio-Legal Review

Organised monument governance in India began during the colonial rule. The colonial governance enterprise was bureaucratic and worked through stringent laws which often came down heavily on the monument-adjacent communities. The totalising nature of Indian colonial governmentality fractured the local community, disabling their engagement with the State either as civil society, as individuals or as social groups, while on the other hand enabling such engagement through a “community” constructed on religious lines. Colonial continuities in monument governance meant that a roughly similar position continued in the post-colony. On the international plane, however, there has been a discursive shift in valorisation …

Discovery Of Bmi-Associated Gut Microbiome Signatures In The Awi-Gen 2 Cohort, Meriem Yagoubi

Theses and Dissertations

Obesity is increasing across sub-Saharan Africa amid rapid dietary, environmental, and urbanization transitions, yet the gut microbiome features associated with adiposity in African populations remain under-characterized. This study investigated whether species-level gut microbiome composition is associated with body mass index (BMI) in the AWI-Gen 2 cohort, and whether BMI-associated microbial signals remain detectable after accounting for the dominant geographic structure of the microbiome. Gut microbiome community structure and diversity were characterized across 1,665 participants, and differential abundance analysis was used to identify taxa associated with BMI after controlling for study site. Machine learning models were then trained to assess how …

Chatgpt, Where Should I Go? A Qualitative Exploration Of How Large Language Models Are Experienced As Support For Travel Planning, Mohammad Amin Kuhail, Asbjørn Følstad, Saifeddin Alimamy

All Works

Large language models (LLMs) are increasingly used for travel planning. Yet, little is known about how travellers experience and interact with such language models. This qualitative study explores how users employ LLMs to plan trips, drawing on the hedonic/pragmatic model of user experience to examine functional and affective dimensions. We collected data from 104 participants with prior experience using LLMs for travel advice through open-ended questionnaire responses. Thematic analysis revealed three key insights: (1) users value the pragmatic benefits of LLMs, such as efficiency, clarity, and confidence in decision-making, while also appreciating hedonic qualities, including inspiration, enjoyment, and authenticity; (2) …

Child undernutrition remains a significant public health challenge in many low and middle-income countries (LMICs), including Lao PDR, where high levels persist even in urban areas with generally available and accessible food. This study aimed to explore factors underlying the persistently high rates of undernutrition among young children in urban (Saysetha) and peri-urban (Pakgneum) districts of the Vientiane Capital in Lao PDR. A cross-sectional survey employed a sequential explanatory mixed-methods approach, combining a structured questionnaire of 333 mother-child pairs for quantitative analysis with semi-structured interviews of 47 caregivers for qualitative insights. The prevalence of malnutrition among children under 24 months …

The Civil Liability Gap For Oil Spills Caused By Non-State Armed Groups: The Case Of The Mv Sounion Tanker In The Red Sea, Emery Hansell

Duke Environmental Law & Policy Forum

On August 21, 2024, the Greek-flagged oil tanker MV SOUNION ("Sounion") was attacked by Houthis as it passed through the Red Sea. The Houthis, a rebel group that controls large swaths of Yemen, then set the ship ablaze, threatening to spill roughly 1 million barrels of crude oil into the water. The cleanup was anticipated to cost $20 billion. The question thus arises: who would—and who should—pay for that cleanup? At the moment, there is no effective solution.

As an initial matter, current international law focuses on State liability and is therefore unlikely to require the Houthis—as a non-State actor—to …

Phasing Out A Way Of Life: How Decarbonization Affects Coal Dependent Communities, Alex Loeb

Duke Environmental Law & Policy Forum

As member states seek to comply with European Union industry rationalization directives that will force mines that cannot compete with free-market prices without subsidies to close, domestic governments across Europe will face competing pressure from civil society. Many traditional European mining communities are dependent on the coal industry and will resist the phase out of its position in the European energy mix. In Asturias, Spain, the phase out of non-competitive coal mines has had devastating impacts on former mining towns, as they struggle to transition to a coal-free economy. After phasing out coal, Asturias has struggled with unemployment and significant …

A Machine Learning Framework For Contractor Scope Matching Using Profile Characteristics And Work Package Vector Similarity, Pedro Fonseca, Sergei Chuprov

Computer Science Faculty Publications

This paper presents a machine learning-based framework for predicting contractor performance in the construction industry by integrating contractor profile information with work package characteristics. The proposed approach addresses procurement challenges arising from the misalignment between contractor expertise and assigned scopes, a key contributor to cost overruns and schedule delays. Unlike existing models that rely on aggregated project-level indicators, the framework enables scope-aware performance prediction by leveraging the Work Breakdown Structure (WBS) to capture similarity among work packages. Contractor profiles are encoded using historical performance data, while WBS elements are vectorized to quantify scope similarity and contextualize predictions. Experimental results demonstrate …

Introduction: The use of artificial intelligence (AI) in the scientific process is advancing at a remarkable speed, thanks to continued innovations in large language models. While AI provides widespread benefits, including editing for fluency and clarity, it also has drawbacks, including fabricated content, perpetuation of bias, and lack of accountability. The editorial board of Regional Anesthesia & Pain Medicine (RAPM) therefore sought to develop best practices for AI usage and disclosure.

Methods: A steering committee from the American Society of Regional Anesthesia and Pain Medicine used a modified Delphi process to address definitions, disclosure requirements, authorship standards, and editorial oversight …

Amc-F1 Regulates Mitochondria-Autophagy Crosstalk Independent Of Nutrient Stress, Yuqin Wang, Raksha K Rao, Trung Vu, Ayano Sekine, Zhengmei Mao, Nami Mccarty

The Brown Foundation: Institute of Molecular Medicine

Mitochondria and autophagy are fundamental yet distinct regulators of cellular homeostasis. Here, we identify AMC-F1 (Autophagy-Mitochondria Coupling Factor 1; formerly TRIM44) as a central integrator of mitochondrial bioenergetics and autophagy. Using Amcf1 knockout and knock-in mouse models, we demonstrate that AMC-F1 bidirectionally regulates these pathways: its loss reduces mitochondrial respiration and autophagic flux, whereas its overexpression promotes mitochondrial elongation and increases autophagy independently of nutrient stress. Transcriptomic analyses reveal AMC-F1-dependent regulation of mitochondrial biogenesis programs that engage autophagy, involving mitochondrial respiratory chain complex genes under basal conditions and mitochondrial organization factors under starvation-induced autophagy. Although dispensable under homeostasis, this coupling …

Participants’ And Physiotherapists’ Views On The Delivery Of A Randomised Controlled Feasibility Trial Investigating A Bespoke Dynamic Elastomeric Fabric Orthosis For Women With Chronic Pelvic Girdle Pain: A Qualitative Exploration, Bradley Halliday, Jennifer Freeman, Sarah Chatfield, Lee Cameron, Kirsty Carter, Joanne Hosking, Jill Shawe

School of Health Professions

Background: Chronic pregnancy-related pelvic girdle pain (PPGP) affects approximately 10–30% of postpartum women beyond 3 months. Such pain is typically recalcitrant to standard care. A dynamic elastomeric fabric orthosis (DEFO) is one option. A feasibility randomised controlled trial (fRCT) assessed the feasibility and acceptability of trial design, interventions and data collection. The aim of this qualitative sub-study was to explore the experience of women participating in the feasibility trial, and physiotherapists delivering the trial intervention. Methods: An embedded qualitative study within a fRCT. The fRCT randomised participants to either control (standard care involving advice and exercise) or intervention (standard care …

The Use Of Surveys In Soliciting Patron Feedback: Effective Strategies For Creating, Promoting, And Applying Them, David J. Fuller

The Christian Librarian

This literature review examines recent sources that explore ways to optimize the helpfulness of surveys in different information organization management contexts. In the landscape of the scholarly literature on using surveys in information organizations, three significant sub-topics for discussion emerge: strategies for incentivizing participation and completion, using surveys in combination with other assessment measures, and formulating action steps from survey results. These three sub-topics are discussed with a focus on common themes, contradictions, and gaps in existing research.

Matching Two Long Interferometric Pathlengths Using Low Temporal Coherence Light For Finding Hong–Ou–Mandel Dip, Keith A. Wyman, Noah S. Everett, Anil K. Patnaik

Faculty Publications

Hong–Ou–Mandel (HOM) dip from a biphoton source in a two-photon interferometer provides a myriad of quantum tools for quantum communication and sensing. But the stringent requirements for spatial coherence between the photon pair makes it prohibitively difficult to observe high-fidelity HOM dip in long-distance free-space implementations, e.g., for the photon pairs involved in quantum communication need to match the two path lengths within a few 10 s of micron because of the short coherence width of the two-photon wave-packet. While many techniques for the pathlength balancing of two interferometric arms have been studied and applied extensively, such balancing is further …
