Antenna-Based Sensors For Dielectric Characterization Of Materials, Hilary Scott Nkimbeng Cho

Dissertations, Master's Theses and Master's Reports

This research introduces antenna-based sensors for dielectric characterization aimed at overcoming the limitations of conventional microwave sensors. Although traditional microwave sensors are widely used for their noncontact operation, high sensitivity, and ability to penetrate various materials, they often face challenges such as large size and high-power consumption. To address these issues, antenna-based sensors are explored for their compactness, ease of fabrication, and flexible design adaptability across diverse sensing applications. An in-depth analysis of multiple antenna sensor configurations is conducted, followed by the design and development of high-performance sensing structures. A saw-tooth slot antenna sensor is developed for highly sensitive liquid …

First-Principles Investigation Of Quasi-One-Dimensional Van Der Waals Magnets For Advancing Low-Dimensional Spintronics, Alyssa Horne

Dissertations, Master's Theses and Master's Reports

Van der Waals (vdW) magnets have been of great interest for advancing low- dimensional spintronics. A notable example is the quasi-one-dimensional (Q1D) vdW CrSbSe₃, as it is composed of individual one-dimensional units that are held together by the vdW forces. Finding other Q1D vdW magnets that exhibit non-metallic behavior together with long range ferromagnetic ordering is critical in developing next generation spintronics. Here in, using first-principles density functional theory (DFT), we investigate the compositional effects on electronic and magnetic behavior of Cr_1–xMn_xSbSe₃ (x = 0, 0.5, 1). When 50% of Cr is replaced …

Beyond Satisfaction: Developing A Data Storytelling Evaluation Protocol For Stem Equity Program Assessment, Karen Colbert

Dissertations, Master's Theses and Master's Reports

Higher education institutions routinely evaluate equity initiatives using measures of participation, engagement, and satisfaction. While these approaches provide useful information about program delivery, they offer limited insight into whether interventions change how participants understand institutional inequities. As a result, important dimensions of organizational learning and awareness often remain difficult to detect, particularly within STEM higher education environments where evaluation systems frequently emphasize measurable outputs over deeper indicators of change.

This dissertation examines how awareness-related outcomes can be identified, measured, and communicated within equity intervention contexts. Using a three-study design, the research first presents a systematic review of equity intervention evaluation …

Valuing Life And Loss: Genre Analysis Of Insurance Claims Processing In Ghana, Cornelius Fuumaale Suom-Kogle

Dissertations, Master's Theses and Master's Reports

This thesis draws on theories from rhetorical genre studies (Spinuzzi’s genre ecology and Freadman’s uptake), biopolitics, and the social justice turn in Technical and Professional Communication to examine how decisions are made in the processing of insurance claims. I adopt a qualitative, interpretive approach to analyze one hundred and twelve (112) claims processing examples from Ghana’s insurance industry. The findings indicate that insurance claims processing is a complex communicative system in which institutional power is enacted, negotiated, and, at times, contested. The findings also reveal that insurer-authored genres frequently enact forms of oppression (exploitation, marginalization, and powerlessness) through technical language …

Enhancing Coastal Vulnerability Assessments And Policy Impacts On Socioeconomic And Environmental Equity In Michigan's Great Lakes Communities, Esther N. Acheampong

Dissertations, Master's Theses and Master's Reports

Accelerating shoreline erosion, fluctuating lake levels, and climate-induced hazards are transforming the Great Lakes’ freshwater coasts, exposing the limitations of static and inequitable management frameworks. This dissertation investigates how Michigan’s coastal governance systems produce and manage vulnerability along the Lake Michigan shoreline by integrating geospatial modeling, institutional policy analysis, and environmental justice theory. It argues that both physical processes and institutional designs co-determine patterns of exposure, protection, and equity. The research begins by developing a refined Coastal Vulnerability Index (CVI) tailored for lacustrine environments, applying it to Muskegon County to assess how shoreline change, armoring, and seasonality influence localized risk. …

Predicting Loneliness Among Older Adults In Ireland Using Supervised Machine Learning, Ariadne Chaves Miranda

ICT

Over the last two decades, technology has grown exponentially and has facilitated communication that helps individuals remain connected. However, this has also contributed to social isolation and lack of physical interaction. One consequence of this phenomenon is loneliness, which is understood as an unpleasant subjective state of discrepancy between the desired amount of companionship or emotional support and what is available in the person’s environment (Prohaska and Burholt, 2020). In the European context, Ireland has emerged as the loneliest country in Europe with 20% of its population that have reported feeling lonely most or all the time (Schnepf et al., …

The Role Of Parent Involvement In Enhancing Pediatric Speech And Language Therapy, Katie Lynch

Honors Program Theses

As speech-language pathologists, we provide speech and language therapy for children in a variety of settings. It is crucial that we include a client’s family in therapy because family involvement has been shown to promote generalization of skills learned in therapy to a child’s typical environment. Despite this, various barriers exist for families as they aim to support their child’s speech and language goals. This literature review examines how speech-language pathologists can gain an understanding of these barriers and how they can promote family involvement in pediatric speech and language therapy.

Growth And Sustainability Of Ash Tree Replacements In Twin Lakes, Iowa, Emma Larsen

Honors Program Theses

The significant loss of mature ash trees at Twin Lakes Bible Camp (TLBC) has motivated efforts to restore green spaces by planting replacement trees. In summer 2024, 32 trees representing eight unique species were planted, and their overall health and site suitability were evaluated to inform future replanting efforts in summer 2025. The five soil series present at TLBC (Canisteo, Clarion, Webster, Okoboki, and Nicollet) were evaluated by soil chemistry testing through x-ray fluorescence spectrometry. This study presents site-specific data of tree growth measurements, visual health assessments, and soil compatibility analyses to identify practical recommendations for improving restoration success. The …

Using Simulations And Machine Learning To Improve Routing Algorithms In Wireless Sensor Networks, Luke Abels

Honors Program Theses

Wireless sensor networks (WSNs) are widely used in fields such as environmental monitoring, smart agriculture, disaster response, and other applications where low-power devices must communicate reliably over time. Because these networks operate under limited energy and communication constraints, routing and broadcast strategies strongly influence performance, scalability, and network lifetime. This thesis examines how simulation and machine learning can be used to study interference-aware broadcasting in WSNs. The project first evaluates the usefulness of existing network simulation tools, including ns-3, and then describes the development of a custom Python simulator designed for rapid experimentation with broadcast behavior, mobility, and signal-to-interference-plus-noise ratio …

Approximation Algorithms For Center-Based K-Clustering, Ankita Sarkar

Dartmouth College Ph.D Dissertations

Center-based metric k-clustering is a rich class of well-studied optimization problems. These include the classical k-center, k-median, and k-means problems. In all these problems, a client set C and a set F of candidate facilities live in a metric space. We are required to pick or "open" k facilities S ⊆ F to minimize some objective function, potentially subject to further constraints on S. Such problems are NP-hard, which has encouraged a long line of research in approximation algorithms for them.

In this thesis, I present research on center-based k-clustering in scenarios where either …

Consensus Decision-Making: Decision-Making Model Of Chinese Constitutional Review, Songfeng Li

Emory International Law Review

The judgment model of constitutional review in China adopts a consensus-based judgment model involving multiple stakeholders, including review authorities, drafting authorities, relevant interest parties, and the general public. Through multi-level, multi-stage, and multi-round interactive communication and negotiation, consensus is reached on constitutional judgments. This judgment model aligns with the power division political system under the NPC system, reflecting the institutional concept of people’s sovereignty and the cultural foundation of valuing harmony. It is also a result of the decentralization of constitutional review authority leading to insufficient power for actual reviewers, the parallel nature of factual and normative judgments in constitutional …

Ocean-driven basal melting of Antarctic ice shelves plays an important role in the mass loss of the Antarctic Ice Sheet. Ice shelf cavity-resolving ocean models are a valuable tool for understanding ice shelf-ocean interactions and for simulating projections of ice shelf and ocean states under future climate. Designed to assess the current state of ice shelf–ocean modelling, the second Ice Shelf–Ocean Model Intercomparison Project, ISOMIP+, consists of 12 ocean model configurations submitted with a common, idealised experimental setup. Here, we focus on the experiments Ocean0–2 (Asay-Davis et al., 2016), which are ocean models with idealised, static ice …

Risk Factors Of Child Sex Trafficking: A Gender-Based Scoping Review In The U.S. And Cross-Border Contexts, Peyton Forbes

Social Work Theses

Child sex trafficking is a major public health issue affecting the youth population of the United States and internationally. This scoping review examines risk factors on multiple levels including individual, family, community, and macro and digital contexts. A systematic search of databases identified 32 studies meeting inclusion criteria. Findings suggest that individual-level risk includes cumulative exposure to violence and trauma, substance use, mental health and behavioral problems, child welfare and justice involvement, runaway behavior, educational disruption, limited social support, and intersection demographic vulnerabilities (e.g., gender, sexuality, race/ethnicity, disability). Family‑level risk reflects unstable or unsafe home environments characterized by substance use, …

Pork, Parties, And Power: Money Politics In Japanese Political Parties, Maya Maranto

HMC Senior Theses

This thesis examines the proposition that the LDP utilizes money politics more than opposition parties in Japan, which could explain why the LDP has remained largely dominant since 1955. Focusing on the House of Representatives elections in 2017, 2021, and 2024, I analyze eight case studies, examine the University of Tokyo-Asahi Shimbun Elite Candidate Survey covering over 90 percent of candidates, and quantitatively analyze party manifestos. I operationalize money politics as reliance on support organizations, support for infrastructure and agriculture, forestry, and fisheries, and support for regional funding. I find that, all measures taken together, the LDP remains the most …

Fear, Delay, And Preventable Death: Rethinking Wyoming's Legislative Framework To Reduce Barriers In Overdose Emergency Reporting, Shoshana Sangros

Wyoming Law Review

This Comment asks whether Wyoming’s current immunity framework for reporting overdoses truly reduces delays in emergency treatment when distance, weather, and limited emergency medical service (EMS) capacity already regularly extend response times. It proposes that by amending two Wyoming statutes and funding statewide education, the goal of reducing barriers to calling 9-1-1 to report overdoses can be better achieved, and residents better protected. To support these proposed changes, Part II provides a concise account of relevant Wyoming statutory protections. Part III proposes specific amendments that would address the on-the-ground challenges of the Wyoming emergency response system. These adjustments will utilize …

“If You Can Do This Job, You Can Do Anything”: An Exploration Of The Lived Experiences Of Early Career Social Workers Engaged With People Living With Hiv/Aids, John J. Edwards

Bryn Mawr College Dissertations and Theses

The HIV/AIDS epidemic, now in its fifth decade, is one of the most consequential health, social, scientific, and political challenges of the modern era. Since its emergence, social work has played a critical role in service provision and advocacy on behalf of people living with HIV/AIDS (PLWHA). Tremendous biomedical advancements over the years have fundamentally transformed HIV from an invariably fatal illness to a chronic and manageable condition. As the profile of HIV has changed over time, less is known about the contemporary experiences of social workers engaged with PLWHA. To address this gap, semi-structured interviews were conducted with early …

To increase CRC screening in primary care practices, our team developed a tablet-based digital health program (mPATH) designed to identify patients needing CRC screening, provide education, and empower patients to request a screening test via the program.

Objective: This study aimed to qualitatively assess facilitators of and barriers to implementing and maintaining mPATH in primary care clinics.

Methods: In a pragmatic implementation trial, clinics were randomized to receive only in-person training and technological support via phone or email (low touch) …

Adipose Tissue-Derived Small Extracellular Vesicles In Plasma Reveal Molecular Circuitries Underlying Glucose Intolerance, Shalini Mishra, Yixin Su, Ashish Kumar, Sangeeta Singh, Brian S. Finlin, Fang-Chi Hsu, Jingyun Lee, Cristina M. Furdui, Philip A. Kern, Swapan K. Das, Gagan Deep

Internal Medicine Faculty Publications

Objective: Glucose tolerance (GT) is a major effector for adipose tissue (AT) remodeling in obesity, yet its molecular mechanisms remain incompletely defined. We hypothesized that the biophysical and molecular profiles of AT-derived small extracellular vesicles (sEV^AT) change in response to glucose availability and differ by GT status.

Methods: sEV^AT were isolated from plasma of individuals with normal GT (NGT) and impaired GT (IGT) (n = 5/group) at fasting (0 h) and 1 h post glucose challenge during oral glucose tolerance test (OGTT). sEV^AT were characterized for size, concentration, surface expression of insulin receptor-α (INSRα), proteome, …

The Bigotry Of The Future: Ai Recruitment Tools & Hiring Discrimination Law, Lily Manshel

City University of New York Law Review

As one-click applications and a competitive job market result in hundreds of applicants per listing, hiring tools that use Artificial Intelligence (“AI”) promise recruiters a convenient way to sort through the crowd and find the “perfect” candidate, all while eliminating human bias. These tools—which include resume screeners, gamified assessments and personality tests, and video interviewing software—are proliferating so rapidly that their ubiquity is positioned as inevitable by both the software companies that produce them and the employers who use them. However, the use of these automated decision-making tools creates a paradox under existing antidiscrimination law: the systems clearly perpetuate and …

Disability As A Critical Element In Exploring The Racial Wealth Gap, Nanette Goodman, Montserrat Avila-Acosta, Fitore Hyseni, Peter Blanck

The Lender Center for Social Justice

This report examines the racial wealth gap for people with disabilities in the United States. While the racial wealth gap is well-documented, with the median White household having a net worth 7-10 times higher than the median Black household, the wealth gap experienced by people with disabilities remains less explored. Recent data show that households without disabilities possess, on average, 6 times the net worth of households led by a working-age person with a disability. Wealth, defined as total household assets minus total liabilities, is a comprehensive measure of economic well-being and social stratification, and it has wide implications, including …
