Black, Owen Streeter, Arianne Sweeting, Pejman Adily, Mark Lauer, Adrienne Gordon, Vincenzo Berghella, Belinda R. Bruce, Lauren Ferris, Bradley De Vries

Department of Obstetrics and Gynecology Faculty Papers

Increasingly the value of gestational weight gain (GWG) as a useful measure to predict obstetric outcomes including cesarean section is being questioned. We will undertake a retrospective cohort study of recorded births in 2023 from 24 to 42 weeks' gestation for women aged from 16 to 49 years in the United States. Using multivariable Robust Poisson Regression, maternal body mass index (BMI) and BMI gain will be modelled on the primary outcome of cesarean delivery. The primary analysis will be restricted to nulliparous women if there is interaction between parity and BMI or BMI gain. A sample of 716,392 births …

The Role Of Social Media In Beauty Marketing: Insights From Kidfluencers, Brand Withdrawal, And Consumers’ Attitudes, Avery Giddings

Business/Business Administration

This thesis examines the evolving role of social media in beauty marketing by analyzing industry trends, ethical considerations, and consumer perceptions. The paper first outlines how social media has transformed digital marketing, enabling brands to merge advertising, community-building, and e-commerce. Two case studies highlight contrasting dynamics within this landscape: the rise of “kidfluencers,” which raises concerns about privacy and potential financial exploitation; and Lush Cosmetics’ decision to withdraw from major social media platforms, a move rooted in ethical branding but accompanied by economic challenges. To further investigate consumer attitudes, a survey of 150 U.S. participants assessed social media usage patterns, …

Training Aba Service Providers To Use Phonemic Transcription: A Comparison Of Two Alphabets, Kristin Marie Albert

Theses and Dissertations

Applied behavior analysis (ABA) service providers regularly develop speech and shape articulation when working with minimally vocal children with autism. However, these providers usually have not received training in related subject areas as part of their certification coursework. This results in a gap between their scopes of competence and practice. The present study aimed to lessen this gap by training ABA service providers to take phonemic transcription. The author, in consultation with a speech-language pathologist, developed and implemented a computer-based programmed instruction training package. Studies 1 and 2 employed a concurrent multiple-probe design with an embedded adapted alternating treatments design …

Infectious Disease Crisis Communication After The Covid-19 Pandemic, Macy Lloyd

Capstone Experience: Master of Public Health

Since the COVID-19 pandemic, the United States has experienced a proliferation of mis- and disinformation, an increasing politicization of health and science, and growing distrust in government, science, and institutions. While these trends present challenges for normal public health communications, during a public health emergency, such as an infectious disease outbreak, these challenges are even more acute. To address challenges at the local level, health departments need plans, products, and tools that adapt health crisis communications to the current media environment and meet community members where they are across the trust continuum. To develop an infectious disease incident communication plan, …

Local Government Standing As State Standing, Katharine Cooney, Katherine Mims Crocker

Faculty Scholarship

It is increasingly common, and controversial, for local governments to bring lawsuits as plaintiffs in federal court. Many questions about this practice raise matters that sound in policy. But some, including the issue of standing to sue, also raise issues of constitutional law. How local governments fit into standing rules should reflect how they fit into the U.S. constitutional system more broadly. As the Supreme Court put it in the famous (and infamous) 1907 case Hunter v. City of Pittsburgh, "[m]unicipal corporations are political subdivisions of the State, created as convenient agencies for exercising such of the governmental powers of …

Introduction Mortality-to-incidence ratios (MIRs) are useful in assessing disease burdens and illustrating disparities. Unlike cancer, MIRs have not been applied to ADRDs. Therefore, we estimated and mapped the MIRs for ADRDs to show disparities in South Carolina. Methods Using data from the South Carolina Alzheimer’s Disease Registry (2017−2021), ADRD MIRs were calculated by demographic and geospatial characteristics. To account for the influence of the COVID-19 pandemic, data from 2015 to 2019 were also examined. MIRs were calculated as age-adjusted mortality rates divided by age-adjusted incidence rates. Results Overall, Black people and rural individuals consistently experienced higher MIRs, with the COVID-19 …

This article reports findings from a mental health-focused telehealth instructional activity integrated into an existing AGACNP curriculum. This instructional activity was designed to introduce students to telehealth delivery and build AGACNP competencies using telehealth technology to assess patients with depressive mood …

Fast & Forensic: Rapid Detection & Quantitation Of 30 + Emerging Novel Psychoactive Substances In Hair Using Lc-Ms/Ms, Seokjin Hwang

Student Theses

The continuous emergence of novel psychoactive substances (NPS) poses a significant challenge for forensic and clinical toxicologists, due to their structural diversity, rapid turnover on the illicit drug market, and limited toxicological information. Hair is a powerful matrix for retrospective drug exposure assessment and monitoring NPS worldwide. Not only does it provide a broad window of detection but also a simple sample exchange amongst laboratories. However, the extraction of multi-class NPS in a single method remains an analytical challenge. Therefore, there is an urgent need for extraction techniques and analytical methods that are both rapid and capable of multi-class quantitation …

Understanding Mental Health Crisis Response Through The Lens Of First Responders, Ella Gibson

Student Theses

Responses to mental health crises are becoming an increasingly contentious topic as cases of extreme police violence or fatality during a crisis are publicized in the media. Although first responders’ experiences with mental health crisis response have been explored in prior literature, there remains a lack of research that gathers data from multiple first responder roles and compares their experiences across groups. There is also a significant gap in research examining the perspectives of co-response teams. This study sought to gather qualitative data on the experiences of police officers, EMTs/paramedics, and co-response team members, and to explore their perceptions of …

Weaponized Deepfakes: A Low-Resourced Attacker Threat Assessment, Joshua David Labelle

Master's Theses and Capstones

The democratization of Artificial Intelligence and Machine Learning (AI/ML) tools, combined with the short-form nature of modern media consumption, has created a ripe landscape for generating and weaponizing synthetic media. The availability of pre-trained, open-source generative models enables would-be attackers, who lack funding and enterprise-grade hardware, to conduct convincing information-based attacks that harm, manipulate, and deceive. This thesis aims to model this threat actor using an open-source deepfake generation pipeline that requires minimal computational resources and is capable of producing deepfakes in the audio, image, and video domains. This model is then used to identify, measure, and evaluate the capabilities …

The Plymouth Student Scientist

The feedback concealed information test (fCIT) incorporates feedback on memory concealment performance within the classical CIT. Providing feedback facilitates the analysis of feedback related ERPs in addition to initial recognition related ERPs within each trial. Combining multiple ERPs aims to improve the reliability and efficiency of the test. The present study investigated the efficiency of combining recognition and feedback related P300 ERPs in detecting concealed birthdates in a personal item fCIT. Feedback proportions were altered to improve believability in feedback. Detection efficiencies using combined P300 amplitudes within this altered paradigm and the impacts of social pressures on feedback P300s were …

What Environmental Circumstances Generate Hazardous Wave Overtopping Conditions For Infrastructure Disruption: Dawlish (United Kingdom) Case Study, Zbigniew Tomasz Zielonka

The Plymouth Student Scientist

Coastal infrastructure faces increasing threats from wave overtopping due to climate change, rising sea levels, and intensifying storms. This research investigates the environmental conditions that drive hazardous wave overtopping using Dawlish, a vulnerable section of the UK’s railway, as a case study. Understanding these conditions is essential for improving knowledge, developing effective mitigation strategies, and enhancing the resilience of shoreline defences against future challenges. Using one-year observations from WireWall instruments, offshore wave buoy, and meteorological data, the research applies a Random Forest model to assess the influence of metocean conditions on overtopping. The results indicate that wave height, tidal level, …

Assessing Overtopping Hazard To The Dawlish Railway Line: Integrating Wave Propagation Models For Coastal Metocean Condition Analysis, Matthew R. Owen

The Plymouth Student Scientist

With rising sea levels and increasingly frequent and intense storms due to climate change, coastal communities and structures are at an increasing risk of overtopping occurring. This study investigates the coastal metocean conditions responsible for overtopping at coastal defences, using Delft3D to model these processes with Dawlish as the case study site. Wave propagation models were employed to simulate metocean conditions from December 2021 to March 2022 to compare inshore wave conditions, alongside water level and wind parameters, with observed overtopping data from the WireWall system installed on top of the seawall, next to the railway line. The results indicate …

Otherwise Than Human: Responsibility In The Wake Of Disaster, An Eco-Deconstructive Response To Climate Catastrophe, James W. Harris

Masters Theses and Doctoral Dissertations

This thesis will, firstly, assume a line of eco-deconstructive reasoning, which takes as its point of departure from other approaches to the environment the basic premises of deconstruction, which aim to de-center the ontological and epistemological assumptions of Western thought about the subject and language, and apply it to the concept of the human as a distinct and, most importantly, privileged being as this privilege has operated within language and culture, thereby demonstrating how climate catastrophe constitutes a fundamental rupture in traditional ontology. Secondly, I will turn towards the ethics of Emmanuel Levinas, as in present in his God, Death, …

This mixed-methods study examined the influence of trauma-informed self-care (TISC) practices on compassion satisfaction, compassion fatigue, secondary traumatic stress (STS), and burnout among K–12 educators in a large southeastern Tennessee district, including Priority Schools serving high-poverty communities. A total of 157 educators were surveyed, while 32 educators participated in focus groups to provide deeper insight into self-care supports. Quantitative analyses revealed that higher levels of TISC engagement were significantly associated with increased compassion satisfaction and personal accomplishment, and …

A Question To Query Llm As A Pipeline Replacement In Knowledge Graph Question Answering Systems, Major Schwartz

Masters Theses and Doctoral Dissertations

Knowledge Graph Question Answering (KGQA) pipelines commonly depend on separate entity and relation predictors before querying the graph, which introduces engineering complexity and costly inference passes over large vocabularies. This thesis presents a drop-in replacement for those modules: a fine-tuned large language model (LLM) that translates a natural-language question directly into an executable SPARQL query. We fine-tune instruction-tuned backbones, Llama-3.1-8B-Instruct and Mistral-7B-Instruct, on paired (question, gold SPARQL) examples, which are formatted through chat templates. As a result, the models can perform single-step query generation. The training and inference pipeline includes a lightweight post-processor that corrects tokenizer-induced spacing artifacts in generated …

A Phylogenetic And Taxonomic Analysis Of Parocnus Serus, An Extinct Holocene Sloth From Haiti, Julia L. Jones

Masters Theses and Doctoral Dissertations

Parocnus serus belongs to a unique radiation of extinct ground sloths endemic to the Antillean islands that was discovered in 1929, but, prior to this thesis, it had not been described in detail or had its phylogenetic and taxonomic relationships with other Antillean sloths extensively analyzed. This detailed description of skull and mandible specimens supported the distinctiveness of the genus Parocnus, and the existing size-based separation of the Antillean megalonychids. A morphological phylogenetic analysis of a sample of Antillean sloths supported the close relationship between P. serus and P. torrei but did not provide conclusive results on the relationships among …
