Through Our Eyes: An Exploration Of Hope Among Opportunity Youth, Judith L. Fenlon

Electronic Theses & Dissertations (2024 - present)

Opportunity youth—young people aged 16–24 who are disconnected from both school and employment—experience significant barriers to successful transitions into adulthood. Existing research has largely focused on deficits, risk factors, and outcomes associated with disconnection, often overlooking the strengths, resilience, and aspirations of these young people. Hope has been identified as a critical factor associated with educational achievement, psychological well-being and future orientation; however, little research has explored how opportunity youth experience hope in the context of systemic inequities. The purpose of this study was to explore the lived experience of hope among low-income opportunity youth and to examine the factors …

Audiovisual Motion Onset Asynchrony As Expectation Violation: Effects On Memory And Liking In Media Contexts, Sijia Song

Electronic Theses & Dissertations (2024 - present)

This research presents the first systematic investigation of motion-onset asynchrony (MOA) as a form of audiovisual temporal incongruency grounded in contemporary spatial audio and extended reality (xR) systems. MOA—the delay between the onset of visual and auditory motion—was manipulated at three levels (0 s, 1.1 s, 3 s) to test its effects on cognitive (memory) and affective (liking) outcomes during short 2D animated video viewing. Guided by inverted-U models of expectation violation, it was hypothesized that moderate MOA would be associated with the highest memory performance and liking ratings and that liking would mediate MOA’s effects on memory. Across two …

The Instruments Of Chinese Economic Statecraft, Wilson Han

Electronic Theses & Dissertations (2024 - present)

The global economic order is undergoing a profound transformation as China increasingly leverages its vast commercial resources not merely for market expansion, but as strategic instruments to reshape global governance and secure its national interests. Moving beyond traditional analyses that rely on aggregate macroeconomic indicators, this dissertation investigates the targeted, highly asymmetrical mechanisms of Beijing’s economic statecraft. It systematically examines three specific instruments – institutional, financial, and trade – through which China projects structural power and constructs an alternative economic order.

The first empirical study explores China’s institutional statecraft by analyzing its bid to join the Comprehensive and Progressive Agreement …

Making Words Count: Computational Linguistics In Management Research, Joseph J. Simpson, Richard A. Hunt, David M. Townsend, Judy Rady, Elham Asgari, Mohammad Rady, Daniel J. Beal

International Business and Entrepreneurship Faculty Publications

In recent years, a rapidly growing number of management scholars are using computational linguistics (CL) to analyze vast corpora of naturally occurring organizational language. Yet the rapid adoption of CL methods has outpaced the development of shared standards for linking theoretical constructs, linguistic data, and computational measurement. We synthesize 353 articles published in leading management journals for 2013–2025, identifying four recurring challenges shaping the credibility of CL-based research: misalignment between constructs and textual corpora, unnecessary model complexity, the opacity of large language model workflows, and insufficient transparency in reporting. Building on these patterns, we develop four integrative design principles—construct-language fit, …

Identification Of Neural Crest And Melanoma Cancer Cell Invasion And Migration Genes Using High-Throughput Screening And Deep Attention Networks., J C Kasemeier-Kulesa, S Martina Perez, R E Baker, Paul M. Kulesa

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Cell migration and invasion are well-coordinated in development and disease but remain poorly understood. We previously showed that the neural crest (NC) cell migratory wavefront shares a 45-gene panel with other cell invasion phenomena. To rapidly and systematically identify critical genes, we performed a high-throughput siRNA screen and statistical and deep learning analyses to determine changes in NC- versus non-NC-derived human cell line behaviors.

RESULTS: We find 14 out of 45 genes significantly reduced c8161 melanoma cell migration; four of the 14 genes altered leader cell motility (BMP4, ITGB1, KCNE3, and RASGRP1). Deep learning identified marked disruptions in cell-neighbor …

Designed Lands©Apes—Ar©Hitecture, Sculpture, Visual Art, Shape, Pi©Torial Work, Or . . . Nothing At All?, Richard H. Chused

Articles & Chapters

This article arises from the saga of the construction and eventual destruction of a landmark landscape architectural work by the well-known artist Mary Miss that was constructed adjacent to the Des Moines Art Center called Greenwood Pond: Double Site. The project’s demise is emblematic of the remarkably ambiguous copyright problems that surround such artistic creations. They do not neatly fit into any category of copyrightable works. Though they may contain sculptural works, their overall designs are rarely totally sculptural. While architects typically draw plans and “sculpt” a landscaped space, the results usually are not “buildings,’ as required by the definition …

Exploring The Acceptability Of Integrating Dietitians Into Primary Care Dental Services For Children, Lauren Hallewell, Raul Bescos, Zoe Brookes, Tracey Parkin, Robert Witton, Patricia Casas-Agustench

School of Health Professions

BACKGROUND: Dental caries is a common childhood non-communicable disease strongly associated with high sugar intake. Beyond oral health, a poor diet can affect children's growth, development, and overall well-being. While dietary advice is central to preventive dental care, some primary care dental clinics have introduced body mass index (BMI) assessments and further dietary advice to address wider nutritional concerns in children. However, these efforts are often constrained by limited nutrition training, time constraints and concerns about sensitivity. Integrating dietitians into primary dental care may help overcome these barriers by enhancing dietary guidance, supporting broader nutritional needs and facilitating structured BMI …

Self-Guided Functional Imagery Training To Reduce Anxiety, Jackie Andrade, Stephanie Hartgen-Walker, Caroline Morgan, Ayan, Idil Aytekin, Khadijah Sekoni, Kardelen Sengul, Jonathan Rhodes

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. Methods: …

Children And Adults Across 15 Countries Believe In Human Uniqueness Of Mind: A Cross-Cultural Investigation Of Cross-Species Mind Perception, Karri Neldner, Luke Maurits, Magie Junker, Lara Abbas, Nayrouz Abbas, Arianna Abis, Federica Amici, Bernardo Arroyo-Garcia, Negar Asghari, Giovanna Barragán Pardo, Zhen Zhang, Junior Peña Chumacero, Ardain Dzabatou, Dustin Eirdosh, Susan Hanisch, Tom Herrnsdorf, Tom Hovehne, Alicia Junker, Patricia Kanngiesser, Felipe Villa Larens, Safaa Mahmoud, Sandra Masaquiza, Iino Masato, Risma Illa Maulany, Tongtong Meng, Kardelen Mutlu, Putu Oka Ngakan, Ebru Peközer, Ljubica Petrović, Mirella Christy Rehatalanit

School of Psychology

The way humans relate to other animals is fundamentally shaped by whether we perceive ourselves as unique, with feelings and thoughts not shared by other animals. How beliefs about animals’ ability to feel and think develop across cultures remains largely unexplored. We asked children and adolescents (4–17 years, N = 1025) and adults (N = 190) from 33 urban and rural communities across 15 countries whether animals have thoughts or feelings (judgments of presence), and whether those thoughts or feelings are human-like (judgments of similarity). Bayesian analyses revealed that participants generally ascribed non-human animals the ability for thoughts and feelings. …

Degrees Of Separation: Grandchildren's Experiences Of Grandparental Brain Tumor Or Stroke, Emily Sapsford, Alyson Norman, Sue Jackson, Josh Deacon, Emily Ravenhill, Pete Keohane

School of Psychology

The impact of acquired brain injury on family members is far reaching. Research has identified experiences of trauma, ambiguous loss and burden of care. Limited research has addressed the ripple effect of brain injury across the wider family. The study aimed to gain a detailed insight into the lived experiences of grandchildren of those who have experienced stroke or brain tumor. Ten participants (eight female and two males aged between 18 and 29) took part in semi-structured interviews about their experiences of grandparental stroke or brain tumor. Data were analyzed using interpretive phenomenological analysis (IPA). Four themes were identified. The …

Psychophysiological Recovery From Viewing Nature And Urban Settings: A Multisite Replication, A. E. Van Den Berg, K. Dijkstra, D. Meuwese, F. Beute, P. M. Darcy, S. Dewitte, B. Gatersleben, C. J. Gidlow, C. M. Hägerhäll, J. A. Hipp, Y. Joye, Y. A.W. De Kort, S. C.M. Lechner, C. Neale, Sang Ode Sang, J. Roe, D. T. Scheepers, K. Smolders, H. Staats, R. S. Steensma, K. J. Wyles, S. L. Koole

School of Psychology

The idea that merely viewing nature can promote stress recovery has profound societal implications, driving the use of nature imagery in the design of environments where access to real nature is limited. Scientific support for this concept originates from a pioneering study by Ulrich et al. (1991), which demonstrated superior psycho-physiological stress recovery during exposure to nature videos compared to urban videos. Despite its influence, this foundational study has never been systematically replicated. To address this gap, ten research teams across the Netherlands, Belgium, the UK, Sweden, and the USA collaborated on a multisite replication. A final sample of 959 …

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 …

The Impact Of Value Homophily, Rational And Emotional Persuasion On Information Passing Of Social Media Advertisements: A Model Comparison Approach, Gloria Hui Wen Liu, Cecil Eng Huang Chua, Neil Chueh An Lee, Jenny Hua Jen Wu

Business and Information Technology Faculty Research & Creative Works

Increasingly, businesses collaborate with influencers and content creators (the source) to advertise on social media, with social media users being exposed to an environment saturated with unsolicited advertisements. With social contacts remaining the most trusted advertisement sources, users' passing of such advertisements helps their dissemination and creates a specific kind of electronic word of mouth called information passing. Information passing involves users forwarding advertisements about products/services to someone else. Prior studies have found at least three factors influence information passing, including value homophily (similarity with the source as perceived by users), rational appeal (information about how a product can meet …

Gubernatorial Re-Election Incentives, Local Investment Bias, And Pension Fund Performance, Hongxian Zhang, Liang Guo, Jun Hao, Yu Liu

Business and Information Technology Faculty Research & Creative Works

We investigate the impact of gubernatorial re-election incentive and political factors on US public pension funds from 1990 to 2022. Our empirical analysis finds no significant overall relationship between gubernatorial re-election incentives and local bias in the full sample. However, the effect of gubernatorial re-election incentives on local bias is influenced by a state's level of corruption. Specifically, in states within the lowest corruption quantile, governors eligible for re-election tend to prioritize local investments to gain consistent support. In contrast, in states within the highest corruption quantile, heightened scrutiny may encourage re-election-eligible governors to adopt conservative investment policies that do …

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 …

Peninsula Medical School

Background and Aims: Increasing reports of plastic accumulation in human tissue have raised concerns about potential adverse health outcomes. Evidence of negative effects of nanoplastics is heterogeneous and provides limited insights into the underlying pathogenic toxicity mechanisms in humans. Methods: In the present study, carboxylate-modified fluorescently labelled polystyrene nanoparticles (PS NPs) were used to investigate uptake and cytotoxicity in three different hepatic models of varying complexity, including HepG2 cells, IHH cells, and human precision-cut liver slices (hPCLS). Results: The results show model- and dose-dependent effects on hepatocytes. 74.2% ± 13.4% of the IHH cells showed PS NPs uptake at 0.1 …

Microplastics, Nanoplastics And Liver Disease: An Emerging Health Concern?, Shilpa Chokshi, Ashwin Dhanda, Matthew E. Cramp, Richard Thompson

Peninsula Medical School

Human liver tissue has been found to contain microplastics and nanoplastics (MNPs), with evidence that hepatic MNP accumulation has markedly increased over the past 10 years, prompting critical questions regarding their potential causal role in liver disease. In cell-based and murine models, MNP exposure can trigger oxidative stress, fibrogenesis and inflammation, pathological features that resemble those of advanced liver disease, suggesting shared mechanistic pathways. Furthermore, the capacity for MNPs to act as vectors for microbial pathogens, antimicrobial resistance, endocrine-disrupting chemicals and carcinogenic additives might have important implications for liver pathology. This Perspective examines emerging evidence on the consequences of MNPs …

Designing A Mobile App For Post Traumatic Stress Disorder: Insights From Lived Experience And Clinical Practice, Rohit Shankar, Richard Laugharne, Michael Loizou, Marius Varga, Sivia Lin, Bojana Daw Srdanovic, Roger Farrell

Peninsula Medical School

Post-traumatic stress disorder (PTSD) is a disabling anxiety disorder precipitated by severe trauma. Many people with this condition have little access to clinical interventions, especially in low-middle-income countries. For the development of any digital health intervention, it is vital to know the opinions of PLE and clinicians to guide the developers. We conducted two focus groups, one with clinicians (n = 5) and one with people with lived experience (PLE) (n = 11), to gain knowledge of their views on the development of a PTSD App. Transcripts of both focus groups were coded and thematically analysed. The key themes that …

Shelled Shut-Ins: A Conditional Escape Task Showing Perceptual Awareness In Hermit Crabs, Ari Drummond, John Spicer, Mark Briffa

School of Biological and Marine Sciences

Sentience is an increasingly popular topic in animal welfare and behavioural research. However, studying sentience can be difficult and contentious. Sentience has frequently been associated with ‘feelings’ and ‘subjective states’ not directly accessible to human observers; thus, investigating awareness in animals could be an alternative approach. Frameworks of awareness have been developed for the experimental examination of cognitive capacities that might underpin ‘feelings’ as affective states and subjective experiences. Using a framework of four hierarchically arranged levels of awareness (that is, perceptual, cognitive, assessment and executive), the awareness of an intertidal crustacean, the common hermit crab, Pagurus bernhardus , was …

Investigating The Potential For First Year Residential Field Courses To Facilitate The Establishment Of Teacher-Student Relationships In Biological Sciences Undergraduate Degrees, Anne Plessis, Alison Stokes

School of Biological and Marine Sciences

Teacher-student relationships (TSRs) in higher education impact many aspects of the student experience, including engagement and performance. However, relatively little is known about the mechanisms of establishment of TSRs, and in particular how these are influenced by specific learning environments and contexts. Here, we undertake an exploratory investigation using first year biological sciences undergraduate residential field courses to examine how this teaching context affected the frequency and nature of teacher student interactions, and consequently the development of TSRs. Data were collected from teacher and student participants using questionnaires and focus groups. We found that interactions during fieldwork took place frequently …

Utilizing A Culture System For Horizontal Cells To Study Neural Circuit Assembly In The Developing Mouse Retina, Ross M Perez, Yong H Park, Ajeet Singh, Collin Todora, Marlon F Mattos, Daniela Becerril, Rajashree Venkatraman, Arlene A Hirano, Nicholas C Brecha, Rinki Ratnapriya, Benjamin J Frankfort, Elizabeth Zuniga-Sanchez

Faculty, Staff and Students Publications

The precise wiring of the nervous system relies on neurons extending their processes at the right time and place to find their appropriate synaptic partner. The mechanisms that determine when and where neurons extend their neurites during synaptogenesis remains a central question in the field. In the present study, we used a cell culture system coupled with live imaging to investigate the wiring mechanisms in the developing mouse retina. We focused on horizontal cells which are a class of interneurons in the outer mouse retina known to synapse selectively to the distinct types of photoreceptors. Previous research has shown horizontal …
