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 …

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 …

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 …

“The True Me”: Unravelling The Dual Narrative Of Borderline Personality Disorder And Autistic Spectrum Disorder, Robin Iliffe-Lewis, Alison Bacon

School of Psychology

Objectives: There is growing recognition that some individuals who receive a diagnosis of Borderline Personality Disorder (BPD) are later diagnosed with autism. However, existing literature on this topic remains limited. This study aimed to explore the experiences of individuals diagnosed with BPD prior to autism, how they made sense of these diagnoses, navigated clinical systems, and learnt to manage the complex challenges associated with this diagnostic sequence.Methods: Thirteen (6 male, 6 female, 1 non-binary) adult participants took part in semi-structured interviews exploring their diagnostic journeys. Reflexive thematic analysis was used to develop a nuanced understanding of their experiences.Results: Three themes …

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 …

School of Psychology

Early learning takes place within complex, multimodal environments where curiosity plays a critical role in guiding exploratory behaviors and supporting cognitive development. While trait curiosity shapes children’s early learning experiences, state curiosity is context-dependent fostering early learning, in-part, through information seeking behaviors. Here, we explore whether state-induced curiosity can influence exploratory behaviors and facilitate word learningwithin a multimodal search task that mirrors real-world learning environments.Children (2.5- to 4-year-olds) will be introduced to novel objects and labels via a storybook. After exposure to each novel object, participants will locate the target object (i.e., a sticker depicting the novel object), hidden within …

Post-Divorce Lgbtq-Parent Families: Navigating Loyalty Conflicts And Stepfamily Closeting, Caroline Sanner, Abbie E. Goldberg, Katherine R. Allen

Psychology

Objective: The purpose of this study was to investigate underexplored dynamics of post-divorce LGBTQ-parent families.

Background: In LGBTQ-parent families in which children were conceived in the context of a prior different-gender partnership, children experience the coinciding events of parental separation and a parent's coming out as LGBTQ. In recent decades, research on LGBTQ-parent families formed following different-gender divorce has stalled, perhaps due to the increasing emphasis on planned LGBTQ-parent families, or families formed after parents have come out.

Method: Twenty-four adults who were born to different-gender married parents (i.e., mother/father families) who divorced when one parent came out as LGBTQ …

The Leeuwenhoek Paradox In Dental Artificial Intelligence: A Narrative Review Of Artificial Intelligence-Detected Subclinical Periapical Changes And Human-Labeled False Positives, Etyene Schnurr, Mario Parra, David M. Kim

Journal of Dental Sciences

This narrative review explores the “Leeuwenhoek Paradox,” a metaphorical and conceptual challenge that arises when artificial intelligence (AI) detects subtle periapical radiological changes that are not visible to human observers. Drawing on evidence from studies using two-dimensional and cone-beam computed tomography (CBCT) imaging, this review critically examined the limitations of human-centered reference standards and recurrent discrepancies in AI-based periapical detection. The literature shows that AI systems frequently detect more periapical alterations than human experts. These findings may reflect early bone changes, as indicated by CBCT-based analyses of bone density and longitudinal observations. The paradox arises because AI identifies subclinical radiographic …

Living With Generative Ai: Considering Constructionist Approaches To Learning And Methodological Implications Of Process Ontologies, Jimin Lee, Nancy Budwig

Psychology

The growing presence of generative artificial intelligence (GenAI) in educational practice raises questions about how learners and educators live with AI and reshapes questions about how learning unfolds across contemporary learning environments. Although research on AI in education has expanded quickly, much of this work continues to frame GenAI in technocentric and static terms, as a tool to be evaluated, rather than as a relational and developmental presence within learners' trajectories. Drawing on constructionist learning theory and post-Cartesian metatheoretical perspectives, this mini review suggests that such framings are insufficient for understanding how learning is enacted in AI-mediated contexts. We propose …

Elastohydrodynamic Propulsion Of A Magnetically Actuated Filament, Sohum Kapadia, Julien Chopin, Arshad Kudrolli

Physics

We investigate the low-Reynolds-number propulsion of a slender elastic filament with a dipolar magnetic head actuated by an oscillating magnetic field in a viscous fluid by studying its strokes and net forward motion. To capture these dynamics, we employ an elastohydrodynamic (EH) framework that couples Euler-Bernoulli beam mechanics with resistive force theory. Unlike prescribed-kinematics models, filament shapes here emerge self-consistently from the actuation and the force and torque boundary conditions (BCs). We demonstrate that viscous boundary contributions are crucial for quantitative agreement and show that the swimming dynamics are governed by the EH length and a magneto-viscous-elastic stroke amplitude introduced …

What Kind Of Democracy Is Energy Democracy? Reconsidering Energy Democracy Through Green Democratic Theory, Eric S. Godoy

Faculty Publications - Philosophy

This study examines an energy democracy framework for guiding a just transition to renewable energy, which incorporates democratic methods and values into energy policy decision-making. But as there are a variety of models of democracy (e.g. liberal, ecological, green republican, and socialist), energy democracy is a complex normative concept, which gives rise to ambiguities and confusions. Drawing from political theory, I argue that identifying with a particular kind of democracy provides the framework with a clearer definition, richer normative grounding, and resources for addressing some limitations its critics have identified, such as the reduction of democracy to participation.

Diverse C–C Bond Formation Reactions Catalyzed By Oxidized Palladium Nanoparticles Supported On Marine Shell Waste Powder Via Additive-Free Deposition–Precipitation, Jian Hou, Garrett M. Milligan, Zhicheng Cai, Jun-Hyun Kim

Faculty Publications – Chemistry

The formation of carbon-carbon (C–C) bonds is central to modern organic synthesis. Although the use of conventional Pd-ligand complexes as homogeneous catalysts results in highly effective yields, these systems often face some limitations including high cost, difficult recyclability, and thermal stability. Here, we demonstrate the utilization of palladium (Pd)-derived metals supported on finely ground marine shell waste as a reactive and recyclable catalyst for diverse C–C bond-forming reactions. Oyster shell powder (OSP) derived from problematic biowaste, primarily composed of calcium carbonate, provides abundant anchoring sites to immobilize Pd ions via an additive-free deposition–precipitation method, followed by thermally-induced conversion into oxidized …

Supporting Teachers’ Learning About Technology Accessibility: A Content Analysis Of Asynchronous Professional Development, Mutiara Syifa, Natalie L. Shaheen

Faculty Publications - College of Education

Accessibility is imperative to providing disabled students a free and appropriate technology-mediated public K-12 education. But according to the literature, teachers often lack the requisite knowledge to ensure the technologies they use are accessible. So, we conducted a study to understand what, if any, asynchronous professional development about technology accessibility was available to teachers and other K-12 professionals. The findings indicate that of the free technology accessibility professional development materials in the sample (a) fewer than 20% are designed for teachers, (b) most provide limited information, and (c) fewer than 9% specifically address science, technology, engineering, and mathematics (STEM) subjects. …

Left-Hand Technique And The Limits Of The Possible, Ricardo Iznaola

Soundboard Scholar

This article conceptualizes classical guitar left-hand technique through a physiomechanical framework that places coordinated movement—particularly shifting—at the center of technical practice. Challenging traditional positional doctrines that privilege static hand forms and digital independence, the author argues that such approaches often disregard the functional anatomy of the limb, resulting in inefficiency, unnecessary tension, and potential injury.   Advancing the principle that form must follow function, the study proposes shifting as the fundamental technical category governing all left-hand procedures. A systematic typology—interpositional, intrapositional, and compound shifting—serves as the basis for analyzing arm-wrist-hand coordination across diverse technical contexts, including extensions and contractions, barrés, slurs, …

Journal of Dental Sciences

Background/purpose Universal health coverage (UHC) ensures access to needed health services without financial hardship. While Taiwan has achieved near-universal coverage for most medical services, domiciliary dental care (DDC) for people with mobility limitations remains poorly integrated into the UHC framework. This study assessed DDC coverage in Taiwan using the World Health Organization UHC framework. Materials and methods Publicly available 2024 data were analyzed for dental institutions, practicing dentists, DDC providers, and long-term care populations across Taiwan's six National Health Insurance (NHI) regions and 22 administrative districts. Geographic distribution was examined using provider density metrics, Lorenz curves, and Gini coefficients. Results …

Structural Design Of Macroporous Layered Double Hydroxide Catalysts: Alleviating Mass Transport Constraints In Bulkier Triglycerides, Nazrizawati Ahmad Tajuddin, Mohamad Hidayat Haider, Nazarudin Nazarudin

Baghdad Science Journal

Layered double hydroxides (LDHs) serve as potential catalysts for biodiesel production through triglyceride (TAG) transesterification; nevertheless, mass transport limitations hinder their effectiveness, especially with larger TAG molecules. This study addresses this limitation by synthesizing macroporous MgAlLDH and ZnAlLDH using a polystyrene templating method. Thorough characterization reveals the successful formation of macroporous structures with significantly increased physicochemical properties and their structural design compared to conventional LDHs. X-ray Diffraction (XRD) confirmed the successful restoration of the LDH structure following calcination and rehydration, with enhanced crystallinity seen in the macroporous materials. The BET surface area analysis revealed a substantial increase (∼10x for MgAlLDH) …

Effect Of Mycovirus Infection On The Hydrolytic Enzymes Activity Of Fusarium Oxysporum F. Sp. Cubense Tropical Race 4, The Causal Agent Of Banana Fusarium Wilt, Zhi-Qin Lai, Clement Kiing Fook Wong, Nor Ismaliza Binti Mohd Ismail, Ganesan Vadamalai

Baghdad Science Journal

Fusarium oxysporum f.sp cubense Tropical Race 4 also known as Fusarium odoratissimum (FO) is a fungal pathogen affecting banana (Musa spp.). It secretes plant cell-wall degrading enzymes (PCWDEs) to penetrate and colonize roots, resulting in wilting symptoms and host death. Mycovirus is a virus that infects fungus. It was discovered that mycovirus could be a biocontrol agent by causing hypovirulence in fungal pathogens, a typical symptom of suppressed pathogenicity of an infected host. Hypovirulence was also associated to reduced PCWDE activity in several plant fungal pathogens. To date, no hypovirulent mycovirus was reported in FO. Hence, this study …
