Adversarial Robustness Of Perceptual Hashing Systems: A Unified Security Evaluation Framework, Avijit Roy

Student Theses

Social network platforms, child safety organizations, and image provenance systems use perceptual hashing to identify known child sexual abuse material (CSAM), support content moderation and reverse image search, and verify image integrity. Perceptual hashing works by producing similar fingerprints for visually similar images, even after common transformations such as compression, resizing, or minor brightness changes. This useful similarity-preserving property also creates an adversarial attack surface, as attackers can use AI-assisted or conventional image manipulation techniques to move a hash across a matching threshold while maintaining visual similarity, often without access to specialized hardware.

The security failures produced by adversarial attacks …

Trace: Temporal Rhetorical Analysis And Consistency Evaluation For Legislative Speech, David Hernandez

Master's Theses

Legislators frequently discuss the same policy issues across multiple hearings and legislative sessions, sometimes maintaining consistent positions and other times modifying or reframing their stance over time. Understanding how these positions evolve is important for analyzing political discourse and democratic accountability, yet identifying such shifts at scale remains difficult.

We introduce TRACE (Temporal Rhetorical Analysis and Consistency Evaluation), a system built on the Digital Democracy Database (DDDB) for detecting rhetorical inconsistency in California legislative hearing testimony. TRACE organizes utterances into speaker-anchored timelines indexed by bill and session, then applies hybrid semantic retrieval — combining dense BGE embeddings with BM25 lexical …

Temporal Integration In Music And Aesthetic Judgments: Assessing Musical Taste Through A Transformer-Based Approach, Sophia M. Senderak

Dissertations, Theses, and Capstone Projects

Music unfolds over time, requiring listeners to integrate information moment by moment to make aesthetic judgments. Although we know that music is likely processed on multiple timescales, it is not known which musical features contribute to short versus long timeframes. This study examined whether a computational measure of temporal integration could help explain aesthetic responses to music. Participants (N = 28) listened to 32 sixty-second clips of classical and electronic music, and continuously rated their enjoyment with a dial. After listening, they then gave an overall liking judgment for each clip. To quantify temporal integration, we derived an integration measure …

Rethinking Ethics For An Era Of Trusted Computational Tools, Kristin M Kostick-Quenet, Meghan Hurley, John Herrington, Eric A Storch

Center for Medical Ethics and Health Policy Staff Publications

Computer perception (CP) technologies are poised to deliver near real-time behavioral insights with high precision. As technical barriers recede, our field's ethical focus must shift from "Can we trust the data?" to "Should we use it here, and how?" We propose a contextual ethics framework that: (1) defines the appropriate scope of CP integration; (2) advocates codesigned roadmaps to manage expectations and epistemic conflict; (3) expands evaluation beyond performance metrics to humanistic outcomes; and (4) anticipates future high performance systems to safeguard dignity, empathy, and shared decision-making in clinical care.

Can Generative Ai Make Farming Decisions? Current Status And Future Pathways: A Case Study In Row Crop Production With Chatgpt, Nipuna Chamara, Yufeng Ge, Joe Luck, Yu Pan, Saleh Taghvaeian, Cory Walters, Christopher Proctor, Daran Rudnick, Daren Redfearn

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The agricultural decision-making process is experience-based, knowledge-dependent, time-sensitive, complex, and driven by historical data. Planting, fertilization, irrigation, and chemigation are key categories in farm decision-making, and currently there is no one-shot decision-support tool that covers all these activities. Generative Artificial Intelligence (AI) models are more advanced than traditional machine learning and deep learning models. These models have been trained on vast amounts of data from the internet, allowing them to accept unstructured data in various forms and generate human-like text, solutions to problems, and scenario predictions. Given this capability, we became interested in exploring the potential of generative AI in …

Daily Problematic Smartphone Use Predicts Decreases In Self-Control Capacity: Evidence From Random-Intercept Cross-Lagged Panel Model, Adalia Yin Hui Goh, Andree Hartanto

Research Collection School of Social Sciences

Amidst the widespread increase in global smartphone screen time and the phenomenon of ‘The Great Exhaustion’, where multiple surveys indicate pervasive tiredness and feelings of being drained, there is growing concern about the link between problematic smartphone use and the capacity for self-control. While numerous studies have investigated the relationship between problematic smartphone use and self-control capacity, they are mostly cross-sectional. Thus, it is unclear whether the lack of capacity for self-control is an antecedent or consequence of problematic smartphone use. Addressing the research gap, we conducted a 7-day diary study to investigate the bidirectional relationship between problematic smartphone use …

This Story surrounds an event that occurred one summer on June 25, 1876, along the banks of the Little Bighorn River in what is now the state of Montana. Seen from a 21st century perch, it is a story of a collision between two very different civilizations or empires. Both empire’s military fought in the manner of their society. This narrative will attempt to balance the believable truth of what happened in that contest between the military representatives of both societies while also trying to tell an engaging story, without drifting into naked partisanship, purple prose, or sensationalism. The narrative …

Assessment Of Information Literacy Instruction In Reference: Applying Vanscoy’S Conceptual And Procedural Framework In Practice, Vanessa Arce

Communications in Information Literacy

The instructional aspect of reference work has long been acknowledged, especially in academic libraries. The current RUSA guidelines include helping users develop information literacy as a goal of reference. In this context, investigating the presence and nature of information literacy instruction can be used to assess the quality of reference services. This study applied Amy VanScoy’s conceptual/procedural framework for point-of-need instruction to a sample of chat reference transcripts at Lehman College, City University of New York. One of the assessment’s goals was to determine the prevalence of instruction and type of knowledge addressed in reference interactions. Another goal was to …

Research Matters: Problem-Setting: A Research Reflection Process, Merinda Kaye Hensley

Communications in Information Literacy

In this inaugural “Research Matters” column, Merinda Kaye Hensley introduces problem-setting as an intentional research reflection process inspired by instructional design. This three-pronged approach invites librarians to examine their research agendas by surfacing prior knowledge, identifying bottlenecks, and creating an assumptions inventory. By interrogating what we think we know and where we struggle in doing research related to information literacy, problem-setting reframes our research processes as a generative, inquiry-driven practice. Drawing on an example from her own research agenda, investigating undergraduate researchers’ understandings of the publication process, Hensley demonstrates how reflective problem-setting can unstick thinking, sharpen questions and energize scholarly …

Investigating The Structural Barriers And Opportunities For End-Of-Life Management Of Agricultural Plastic Waste Within California's Strawberry Industry, Rory M. O'Toole

Master's Theses

Agricultural plastic waste (APW) accounts for a significant and growing share of global plastic pollution, yet no study has documented how APW management functions across a specific crop system from production through end-of-life (EOL). This thesis addresses that gap by examining the structures and valuations that shape current EOL management of plastic mulch (PM) and drip tape (DT) in California's strawberry industry, one of the nation's most plastic-dependent crop systems. Drawing on an ethnographic approach that included 27 semi-structured interviews with stakeholders, as well as site visits, this study traces how APW is produced, valued, and discarded within a structurally …

Development Of A Video-Based Tool To Measure Motor Asymmetry In Infants At Risk For Hemiparesis, Roha Ali

Master's Theses

Congenital hemiparesis is a unilateral motor impairment stemming from brain injury in utero or early postnatally. Hemiparesis can be difficult to detect in early infancy with current clinical tools. Yet, early identification of motor asymmetry could play a key role in the design of effective early intervention and rehabilitation strategies. This thesis presents the development and validation of a video-based tool designed to extract infant limb movement data using DeepLabCut’s (DLC) machine learning network. The pipeline was developed using videos of typically developing (TD) infants and infants with Asymmetric Perinatal Brain Injury (APBI), all at or under 3 months corrected …

Reimagining Power And Practice: Grantee Reporting For Greater Impact, Steven Lafrance, Jamae Morris, Lauri Valerio

The Foundation Review

The evaluation of Robert Wood Johnson Foundation’s (RWJF) Written Reports Alternative Project (WRAP) pilot revealed that Oral and Alternative Reporting (OAR) options offer a practical, values-aligned pathway to equitable, trust-based reporting that reduces burden while improving usefulness with a pathway to scale.

WRAP participants reported strengthened relationships and two-way learning, especially when conversations complemented or replaced written materials.

Recommendations for others considering OAR include: offer and codify choice, center questions that matter, design technology to support multiple formats, compensate grantee time for evaluation or additional learning-related asks, and train staff for relational learning.

RWJF’s experience demonstrates how reporting can be …

Unpacking Assumptions: What Evaluation Capacity Building Looks Like When It’S Optional, Flexible, And Funded, Jennifer Marsack, Martena Reed, Robiel Abraha, Abby Triño, Sara Jones, Brita Blesi

The Foundation Review

Evaluation capacity building (ECB) in the philanthropic sector is often designed around a common set of assumptions: organizations need to be directed toward “correct” evaluation practices, compliance is the primary motivator for engagement, and funder-defined metrics are the most appropriate measure of success. This article challenges these assumptions by sharing insights from a multi-year ECB initiative funded by Houston Endowment called Harnessing the Power of Data.

Drawing on surveys, interviews, and program participation data, the authors explore how co-creating learning goals in a strengths-based structure shifts the evaluation culture of an organization. Key lessons include: (1) how flexibility and alignment …

Calibrations And Compliance: The Role Of Motivations In Policy Instrument Design, Panchali Guha, Ishani Mukherjee

Research Collection School of Social Sciences

Most research on the role of policy calibrations in fostering policy target compliance has focused on the calibration of incentives and deterrents; less attention has been paid to examining the deployment and calibration of a wider range of policy instruments with the intention of eliciting a greater degree of compliance from policy targets with heterogeneous motivations. This article addresses this gap in the literature by empirically testing multiple hypotheses on the relationship between the calibration of different kinds of policy instruments and policy compliance for policy targets characterized by different motivations. Using data from a vignette experiment set in the …

La Espiritualidad: Transmitting Peruvian Culturo-Spiritual Elements Into Occidental Systemic Spaces, Deisy Amorin-Woods

Research outputs 2022 to 2026

This paper is a decolonising, Indigenous qualitative inquiry that integrates elements of critical autoethnography, narrative methods and conceptual analysis to explore how Peruvian Andean cosmology can inform contemporary systems thinking and family therapy practice. Writing as a mestiza, a Peruvian migrant in Australia, the author traces the lived experience of cultural erosion within Western, individualistic contexts and her reconnection with ancestral Andean teachings. These teachings—rooted in reciprocity, ecological attachment, collective responsibility and relational balance—are presented as living epistemologies that offer timely contributions to working therapeutically. The author examines core Andean concepts including ayll (kinship-based community), ayni (sacred reciprocity), Yachay (aprenderes …

The Impact Of Corruption On Private Investment In The Mena Region: An Empirical Study On The Period Of 1996-2023, Mohamed A. El Regdawy

Theses and Dissertations

This study aims to examine and understand empirically the impact of corruption on private investment in the MENA region during the period of 1996-2023, as private investment is a key enabler for sustainable economic growth. To better understand such a relationship, a Pooled Mean Group estimator was implemented to figure out this relationship in both the short run and long run. The findings confirm that in the long run, within the context of MENA, corruption was used as a tool to overcome the lack of quality in the regulations that were supposed to enable the role of the private sector. …

From Institutions To Families: Assessing The Progress Of Egypt’S National Strategy For Alternative Child Care Reform, Yasmine M. El Hagry

Theses and Dissertations

This study serves as a critical mid-term review of the Egyptian National Strategy for Alternative Care for Children and Youth without Parental Care (NACS) (2021-2030). The 10-year strategy overall goal is to shift from institutional care, such as orphanages, to family-based care, such as kafala, the Islamic alternative to legal adoption, for children deprived of parental care. While the global literature strongly advocates deinstitutionalization, empirical research on the operational risks and unintended harms that can arise during such complex transformations remains scarce.

Adapting the International Civil Service Effectiveness (InCiSE) Framework, this research uses a qualitative approach to diagnose the …

The Fivestar Method: An Interchangeable Intervention For Ptsd Nightmares And Waking Traumatic Events, Gregory Sparrow, Valerie Leija, Mark Thurston

Human Development and School Services Faculty Publications

There is a variety of trauma resolution methods that focus on reducing the emotional impact of nightmares and/or waking traumatic memories. The revision of nightmares through imagery rescripting represents one of the effective evidence-based methods. In contrast, traditional dream analysis represents an unlikely intervention for trauma resolution, given cultural assumptions regarding the presumed fixed or predetermined nature of dreams. The co-creative dream paradigm, in contrast, introduces the notion that the dream ego can intervene to shift the dream’s unfoldment toward resolution, both retroactively by reliving the original dream in a new way, and prospectively by preparing for new responses in …

International Students As Vectors Of Informal Diplomacy : Does Soft Power Matter More Than Dollars?, Alexis Carriere

Journal of Comparative & International Higher Education

This article examines the evolving rationales underlying government strategies to attract international students, with a particular focus on their role as vectors of informal diplomacy. While existing scholarship has largely analyzed international student mobility through individual motivations or institutional strategies, this study highlights the state-level logics that frame student mobility as a tool of soft power. Drawing on policy documents, political speeches, and scholarly literature, the article analyzes the approaches of the five permanent members of the United Nations Security Council—countries that remain among the world’s top destinations for international students—across three historical periods: 1945–1990s, 1990s–2010s, and 2010s–2025. Findings reveal …

Interrupted By Design: The Impact Of Push Notifications On Stress And Task Performance, Mia Hohmann

University Honors Theses

As digital communication becomes unavoidable at work, notifications have become one of the most common and overlooked sources of interruption. Drawing from current technostress literature, this study investigates how notifications impact acute and perceived stress as well as task speed and accuracy. In an experimental setting, employed university students (N = 35) completed a data-entry task while receiving either no notifications, task-relevant notifications or task-irrelevant notifications to examine how different types of digital interruptions influenced stress and performance. Stress was measured through a pre- and post-task survey and performance was assessed through both speed and accuracy. Although results showed significant …

Public Attitudes Toward Cascade Genetic Screening In The United States, Hadley Stevens Smith, Emilie S Zoltick, Madison R Hickingbotham, Emily S Bonkowski, Stacey Pereira, Tara A Lavelle, David L Veenstra, Amy L Mcguire, Katherine E Bonini, Leila Jamal

Center for Medical Ethics and Health Policy Staff Publications

Introduction: After a patient receives genetic test results that indicate an actionable health condition, cascade genetic screening (CGS) is the process of evaluating the patient's relatives for a potentially elevated genetic risk of disease. The United States primarily relies on patients to communicate with their relatives, resulting in suboptimal rates of risk communication, familial genetic testing uptake, and risk-reducing interventions. There is ongoing debate about whether and how best to inform relatives of a potentially increased genetic risk.

Methods: We conducted a nationally representative survey of US adults to assess attitudes toward informing at-risk relatives, acceptability of system-mediated communication, and …
