Advancing Understanding Of Lived Experience Of Unhoused People To Reduce Social Stigma And Promote Community Health: A Theoretically-Guided Photovoice Study, B-Rad Stephen Applegate

Graduate Student Theses, Dissertations, & Professional Papers

Homelessness is a persistent public health challenge shaped by structural inequities, stigma, and exclusion from social and health systems. Community-Based Participatory Research (CBPR) has increasingly been used to center the knowledge of people who are unhoused, yet limited attention has been given to the theoretical frameworks guiding this work across disciplines. The purpose of this dissertation was to examine theories and methods used in CBPR with unhoused populations and to explore the extension of Margaret Newman’s Theory of Health as Expanding Consciousness from a nursing-focused theory to a public health framework for understanding lived experience.

Using a scoping review methodology …

Between Care And Protection: Constraints On Political Authority In Kamala Harris's 2024 Presidential Campaign, Marissa Barbara Pax

Graduate Student Theses, Dissertations, & Professional Papers

Competing expectations about strength, care, and protection shape how presidential leadership and authority are constructed in contemporary U.S. politics, particularly for members of marginalized communities. This thesis examines Kamala Harris’s 2024 presidential campaign as a case study to explore how candidates negotiate competing understandings of political authority through appeals to Lakoff’s (2002, 2008) Strict Father Morality and the Nurturant Parent Morality. An analysis of her campaign reveals that Harris repeatedly appeals to both moral frameworks, constructing authority through empathy, mutual responsibility, and care while also emphasizing threat identification, protection, discipline, and moral strength. Although Harris successfully mobilizes the rhetorical resources …

High Algal Biomass Is Decoupled From Metabolism In The Gallatin River, Cora Mae Steinbach

Graduate Student Theses, Dissertations, & Professional Papers

Assessing eutrophication in rivers is difficult compared to lakes and coastal waters, because most algal biomass occurs on the riverbed and flows interact and co-vary with production (Biggs and Close, 1989; Bernhardt et al., 2018). Riverine eutrophication is typically assessed using algal biomass and water column nutrients (U.S. Environmental Protection Agency, 2000), but biomass is highly variable and labor-intensive to measure, while nutrient concentrations often underestimate enrichment due to rapid biological uptake (Dodds and Smith, 2016). Reach-scale river metabolism can help evaluate long-term functional change in rivers recovering from nutrient enrichment (Arroita et al., 2019; Jankowski et al., 2021; Diamond …

The Experience Of A Single Parent Participating In Child-Parent Relationship Therapy: An Instrumental Single-Case Study, Matthew Nicholas Schramm

Graduate Student Theses, Dissertations, & Professional Papers

Traditional family structures in the United States have shifted significantly, with single-parent households facing systemic barriers that increase parental stress and strain the parent-child relationship. As this bond is critical for healthy child development, accessible mental health support is essential for these families (Parache et al., 2023).

Child Parent Relationship Therapy (CPRT), a ten-week evidence-based program, strengthens this bond by training caregivers to use play as a therapeutic tool (Landreth & Bratton, 2020). This instrumental single case study (Stake, 1995) examined one single-parent's experience of CPRT delivered in a condensed four-week telehealth format, addressing the limited representation of single-parent households …

An Evidence Review Of Technology Enabled Social Care In The Uk: Report For Cornwall Health Determinants Research Collaboration, Sheena Asthana, Michael Loizou, Marius Varga, Oliver Beer, Rory Baxter, Kieran Green

School of Nursing and Midwifery

The Urgent Need for a Shift from Crisis Intervention to Prevention. As highlighted by the Chief Medical Officer, demographic ageing—particularly acute in coastal areas like Cornwall—necessitates a fundamental shift in care models to allow individuals to live as independently as possible. Currently, the potential of digital technologies to support this aim is not being realised. To maintain wellbeing and reduce demand on statutory services, the system must pivot from reactive crisis management to a greater focus on prevention. While technology can play a pivotal role, it will only succeed if integrated into interoperable, data-driven systems that facilitate early intervention and …

School of Nursing and Midwifery

This narrative review investigates the influence of child-specific content within pre-registration nursing programs on newly qualified nurses’ perceptions of preparedness to care for children, young people, and their families. Despite international recognition of the specialised competencies required for pediatric nursing, the proportion and quality of child-focused education across Higher Education Institutions is not clear. The Population, Exposure, Outcome framework provided a comprehensive search strategy applied across eight databases to identify relevant studies that met the inclusion and exclusion criteria. Of 663 records identified, 451 were screened and 25 full texts wereassessed for eligibility by two reviewers. No studies met the …

Enhancing Monitoring In Protected Areas: Evaluating Mobile Apps As A Tourism Proxy, Jorge Costa, Alberto Gomes, Martin Stokes, Miguel Saraiva

School of Geography, Earth and Environmental Sciences

Crowdsourced data, such as that from mobile fitness apps (MFAs), has the potential to transform tourism research. This opportunity is particularly valuable as tourism to protected areas (PAs) increases, making it more difficult to manage their environmental impacts. However, such data sources come with challenges. Therefore, their representativeness should be carefully evaluated, particularly as their use continues to grow. We use the Paiva Walkways (Portugal) to assess MFAs as a tourism proxy using Spearman’s rank correlation, to evaluate kernel density and fishnet methods for spatialising visitor movements, and to analyse the visitors’ spatiotemporal behaviour using GIS, kernel density estimation, and …

Cryogenic Sloshing In Aircraft Fuel Tanks, Stuart Colville

School of Engineering, Computing and Mathematics Theses

Liquid sloshing in next-generation sub-cooled liquid hydrogen aircraft fuel tanks can induce rapid ullage pressure and temperature drops, potentially causing cavitation in cryogenic pumping systems and compromising fuel delivery systems. Sloshing events may be initiated during taxiing, take-off, landing, and turbulence, with large accelerations producing highly non-linear liquid motion and wave-breaking conditions. Understanding such phenomena is essential for cryogenic hydrogen fuel tank design and certification for next generation aircraft.A systematic experimental methodology was employed to investigate both the wave kinematic and thermodynamic aspects of sloshing. Initial water–air experiments in a simplified horizontal circular tank were conducted to validate measurement techniques, …

Digitalisation In The Voluntary Sector: An Empirical Study On The Determinants Of It Acceptance, Deniz Dogu

School of Engineering, Computing and Mathematics Theses

Digitalisation represents a major societal trend that drives economic and social trans-formation by increasingly embedding digital information and communication techno-logies (ICT) into processes, interactions, and everyday activities across all domains of life. However, the voluntary sector has yet to fully embrace ICT. The extent to which volunteers integrate digital tools depends on factors such as technical infrastructure and willingness to adopt IT. Research in this area remains limited, and findings are often difficult to transfer across different national contexts. This PhD research addresses the gap in understanding IT acceptance in volunteering, using Germany as a case study. A comprehensive literature …

Coupled Thermo-Structural Analysis Of Steel Reinforced Geopolymer Concrete Structural Members, Bin Zhang

School of Engineering, Computing and Mathematics Theses

This thesis investigates the coupled thermal, flexural and steel–concrete bond response of steel-reinforced geopolymer concrete (GPC) and ordinary Portland cement concrete (OPCC) beam cross-sections subjected to one-sided standard fire exposure. A sequential analytical framework is developed to link transient heat-transfer analysis, temperature-dependent sectional flexural analysis, and temperature-dependent bond and flexural–bond coupling assessment.The thermal analysis is performed using a one-dimensional transient heat-conduction model implemented in MATLAB PDEPE. Separate temperature-dependent density, specific-heat and thermal-conductivity relationships are adopted for OPCC and GPC. A dedicated OPCC model of the B1 validation specimen is assessed against 13 matched experimental reinforcement-temperature measurements, giving R^2=0.9542 and an …

Modelling And Optimisation Of Dynamic Power Cable Configurations For Floating Offshore Renewable Energy, Anna Holcombe

School of Engineering, Computing and Mathematics Theses

Floating offshore renewable energy requires dynamic power cables to transmit generated electricity from the floating device to the seabed, or to an adjacent device, so that it can be exported to shore. Dynamic power cables are connected at the top end to a floating device, and traverse the water column, subjected to loading at the hang-off, and direct hydrodynamic loading from waves and currents. Their reliability has been a concern within industry and research, particularly due to historically high failure rates of static subsea cables. It is essential that design and analysis of dynamic power cables is accurate, to mitigate …

Thermal Barrier Coatings And Their Impact On The Mechanical And Thermal Behaviour Of Fused Deposition Modelled Polymers In Harsh Environments, Simon Weait

School of Engineering, Computing and Mathematics Theses

Coordinated deployment of thermally protected unmanned aerial vehicles (UAVs)equipped for active firefighting operations around incidents such as the GrenfellTower fire could have provided substantial support to life-saving efforts. Incurrent practice, UAVs employed in comparable emergencies are largelyconfined to observational and surveillance roles, thereby substantiallyunderutilising their potential. Expanding their use to direct firefighting tasksrequires the integration of advanced thermal protection systems capable ofwithstanding significantly elevated temperatures associated with carbonaceousfire plumes. In particular, the development of a lightweight thermal barrier coatingthat adheres reliably to fused deposition modelled (FDM) polymers, such aspolylactic acid (GTP), is critical for operational viability and the minimisation ofthe …

School of Psychology

Objectives: Many university students experience high anxiety but have limited access to effective interventions. We evaluated a novel digital intervention for anxiety based on functional imagery training (FIT), designed to help individuals identify the impacts of anxiety, set engagement goals, and strengthen motivation for change. Functional Imagery for Keeping Anxiety low (FIKA) uses speak-aloud tasks, journalling, empathic questions, and personalised guided imagery for a person-centred approach. It builds motivation for engagement goals over safety goals through development and practice of vivid and emotionally laden multisensory imagery. Design: Study 1 used semi-structured interviews and thematic analysis to explore user experiences of …

Dampened Social Motivation In Dysphoria: The Role Of Negative Social Expectancies And Internal Causal Attribution Style, Julie L Ji, Nilly Mor, Colin Macleod

School of Psychology

Dysphoria is associated with dampening of social interaction intention, but the cognitive mechanisms that underpin this relationship are under-investigated. This study tested the hypothesis that heightened negative social expectancies mediate the association between dysphoria and dampened social motivation. Additionally, it tested the hypothesis that the association between dysphoria and negative social expectancies is mediated by an attribution style bias that attributes negative, but not positive, outcomes to internal causes. University students (N = 271) with varied levels of dysphoria read vignettes describing hypothetical situations where they initiate a social interaction that results in positive or negative outcomes. Participants rated their …

Training Healthcare Professionals To Deliver A Group-Based Intervention For People Living With Severe Obesity: Lessons From The Progroup Feasibility Trial, Shokraneh Moghadam, Mark Tarrant, Lily Hawkins, Dawn Swancutt, Rod Sheaff, Laura Hollands, Raff Calitri, Jonathan Pinkney, Jenny Lloyd

School of Psychology

Introduction: Group-based programmes are increasingly adopted to support people living with obesity, as they have the potential to reduce staff time and costs and enhance motivation and capability for behaviour change. Group-based programmes could also provide members with opportunities to form meaningful social connections. As such, training should equip healthcare professionals to deliver group interventions successfully and be accessible and feasible for them to complete. This study presents how mixed-methods process evaluation data from the feasibility randomised controlled trial of PROGROUP (a group-based weight management intervention for people living with severe obesity) informed optimisation of the PROGROUP training programme.

Others’ Requests May Dampen The Desire To Do Good: The Effect Of Requests On Children's Prosocial Motivation Across Five Cultures., Anneliese Skrobanek, Patricia Kanngiesser, Jahnavi Sunderarajan, Jorge David Mantilla Salgado, Saiwa Sisa Quimbo Yacelga, Shoji Itakura, Marie M. Morita, Masanori Yamaguchi, Nadia Chernyak, Lucy M. Stowe, Joscha Kärtner

School of Psychology

There exists cultural variation in how people react to prosocial obligations, but we still know little about when these differences emerge in development and how they can be explained. We investigated this in a study with 6- to 11-year-old children (N = 686) in five cultural contexts. Children listened to scenarios about spontaneous and requested (within-subjects) helping and sharing. They rated requested scenarios as less desirable and less satisfying, but there was significant cross-cultural variation in the magnitude of this effect, which was mostly stable with age. We also measured children's sense of individual agency and internalization of prosocial norms …

Integrating Neuroscience And Social Psychology In Researching Interprofessional Education: The Inspire Framework, Kimberley Schenke, Pamela Rae, Jaysan Charlesford, Phil Gee

School of Psychology

There is an increasing focus on the importance of interprofessional education as an integral part of health and social care training. However, the fundamental psychological processes underlying successful interprofessional education are not well understood. Here we propose a single framework, Integrating Neuroscience and Social Psychology In Researching Interprofessional Education (INSPIRE), grounded in evidence from social psychology and neuroscience that could be used to generate testable hypotheses to inform the design, development and evaluation of interprofessional education. The application of this framework offers a novel, scientifically grounded approach to improving the learning outcomes of interprofessional education and provides a foundation for …

Picturing The Past: The Role Of Photo Cue Visual Perspective On Positive Autobiographical Memory Recall In Dysphoria, Sarah Snow, Zachary Adolph Niese, Julie L Ji

School of Psychology

Positive autobiographical memory plays a key role in emotional well-being and is distorted by cognitive processing biases in dysphoria. This experiment investigated how the visual perspectives (first-person vs. third-person) of personal photographs influence recall of positive memories depending on dysphoria. Eighty-five participants (42 low dysphoria, 43 high dysphoria) submitted photos of positive events from both perspectives. Later, participants recalled these events while viewing either a first- or third-person photo before rating and describing their memory. While first-person photos promoted more recall from an own-eyes vantage point regardless of dysphoria level, dysphoria was still associated with greater observer-like recall, reduced mental …

School of Psychology

Background: This service evaluation focused on support workers' perceptions of Video Interaction Guidance (VIG) offered by an NHS Community Learning Disabilities Team. Methods: A mixed-methods design was employed. Support workers developed goals and rated their progress before and after VIG sessions. Thematic analysis was used to analyse qualitative data on the nature of the goals developed, and the strengths and working points identified. The differences between progress ratings before and after VIG were analysed using the Wilcoxon signed-rank test. Retrospective interviews helped to further understand support workers' experiences of VIG. Findings: Support workers identified goals, strengths and working points that …

The Role Of Conflicting Cognitions In Changing Hazardous Consumer Behaviour, Krzysztof Kubacki, Krzysztof Stepaniuk, Dariusz Siemieniako, Karolina Małagocka, Chrystyna Misiewicz

Plymouth Business School

Despite diverse approaches deployed worldwide to address harmful alcohol consumption, understanding binge drinking as a hazardous consumption behaviour remains a pressing issue in marketing and consumer behaviour research. Thus, this study examines the role of cognitive dissonance – and its absence – in facilitating transitions between different phases of binge drinking. Drawing on 38 biographical interviews conducted in Australia, the Netherlands, Poland, and the United States, we identify six instances where cognitive dissonance, or the absence thereof, contributes to the transition into, between, and out of phases of binge drinking. By examining conflicting cognitions that emerge from the gaps between …

A Novel 3d Imaging Approach To Study Evolutionary Innovations In Solanaceae Inflorescences, Devin L. Jackson, Joonseog Kim, Wenheng Zhang Dr.

Undergraduate Research Posters

Understanding the relatedness of angiosperms and the evolution of their inflorescence remains challenging, as these structures are highly modified and prone to convergent evolution. The current research describing inflorescence architecture, whether genetically or morphologically focused, typically relies on text based explanations, 2D images, or 3D based models created with CAD modeling software. This creates a disparity in the reader's understanding of these models since descriptions rely heavily on the author's interpretation of the inflorescence. The goal of our study is to bridge this disconnection by producing anatomically and color-correct 3D inflorescence models using Solanaceae flowers that readers can explore directly, …

Neuron-Enriched Extracellular Vesicle Micrornas Reflect Hormonal Suppression Associated With Oral Contraceptive Use In Young Women, Amulya Chowdhory, Rebekah Frye, Roxann Roberson-Nay

Undergraduate Research Posters

Hormonal contraceptives alter hypothalamic–pituitary–ovarian (HPO) feedback, but their impact on brain-associated molecular communication remains poorly understood. Neuron- enriched extracellular vesicle (nEV) microRNAs (miRNAs), isolated from plasma, provide a minimally invasive window into brain molecular activity. This pilot study examined nEV miRNA expression in young women (ages 18–22) who were either naturally cycling or using a combined monophasic oral contraceptive (OC) pill. To identify hormonally responsive miRNAs, we calculated effect sizes (Cohen’s d) between the two groups and selected those showing large between-group differences (|d| ≥ 0.8). These miRNAs were entered into a principal component analysis (PCA) to reduce dimensionality, and …

From Custody To Care: Understanding Mental Health And Recidivism In The Criminal Justice System, India Cox

Undergraduate Research Posters

Previous studies on genetic influences in mental health disorders have been shown to correlate with incarceration rates in families. Consequently, there are individuals within the criminal justice system under the clinical threshold of a mental health diagnosis; it has been found that almost half of the incarcerated population was arrested due to acting upon their mental health disorder, while 27 to 38 percent developed PTSD while imprisoned. Furthermore, the serious and exhausting cycle of recidivism within the criminal justice system highlights the failure to provide the necessary mental health treatment required to support rehabilitation while incarcerated and prevent reoffending upon …

Bridging The Gap: Why Circulating Micrornas Have Yet To Become Clinical Biomarkers For Endometriosis, Anisha Addepalli, Mary C. Boyes

Undergraduate Research Posters

Endometriosis is a chronic inflammatory disorder in which endometrial-like tissue grows  outside the uterus, leading to pelvic pain, infertility, and diagnostic delays due to the current  reliance on invasive laparoscopy. Although imaging and hormonal assays offer limited accuracy in diagnosing the disease, circulating microRNAs (miRNAs) in arterial blood have emerged as a  promising alternative method as noninvasive biomarkers because they regulate gene expression,  reflect inflammatory and angiogenic pathways, and remain stable in circulation. I propose  investigating miRNAs such as miR-17-5p, miR-451a, and the let-7 family because of their direct  involvement in the regulation of processes such as cell proliferation, immune …

Exploring The Impact Of Skin Tone Satisfaction On Racial-Ethnic-Cultural Belonging Among Latiné Caregivers, Nithya Angadi, Raven J. Bacchas, Fantasy T. Lozada, Chelsea Derlan Williams

Undergraduate Research Posters

A sense of racial-ethnic-cultural belonging (REC-B) is a key process that supports wellbeing and ethnic-racial identity (ERI) development across the lifespan. Yet, little research has examined how phenotypic characteristics may shape belonging within caregivers. While the impact of skin tone on Latiné families has been examined, understanding caregivers' feelings towards their skin tone is essential due to its potential impact on their identity. The current study aimed to investigate whether skin tone and skin tone satisfaction predicts REC-B within Latiné caregivers. This study contributes to understanding how phenotypic factors shape belonging-related identity processes throughout adulthood.

Participants included 113 Latiné caregivers …

Llm-Driven Weekly Newsletter To Assess Open Source Software Project Github Health, Christian Novalski, Christopher Chavez, Ghalian Fayyadh, Kostadin Damevski

Undergraduate Research Posters

Open Source Software (OSS) projects increasingly depend on a diverse set of contributors, including episodic participants who contribute intermittently. Episodic contributors represent a large portion of OSS communities, yet projects often struggle to retain them, leading to decreased project health and continuity. While dashboards and real-time communication tools support continuously active contributors, they often fail to serve the unique needs of episodic participants, who may struggle to remain informed and re-engage with project activity after periods of absence. In this study, we examine the effect of a weekly, email-based newsletter intervention designed to improve awareness and engagement among episodic OSS …
