Testing The Transferability Of Ai Models For Cold-Water Coral Detection And Classification, Kyran P. Graves, Louise Allcock, David K.A. Barnes, Amelia E.H. Bridges, Kerry L. Howell

School of Biological and Marine Sciences

The proliferation of accessible deep-water imaging platforms has resulted in the acquisition of vast amounts of image data, resulting in an analysis bottleneck. Object detection is now being applied to assist the image annotation process, with the potential to reduce analysis time. However, for object detectors to effectively tackle the scale of the challenge, models need to be generalisable to allow the transfer between imaging platforms and in space. This study trains YOLOv5 object detection models to identify six coral morphology groups using annotated imagery collected by ROV ISIS in the UK (JC136). Model performance was tested with independent datasets …

Small-Molecule Therapies Targeting Tumor-Associated Macrophages In Glioma: Mechanisms And Potential, Hua Wang, Heng Luo, Haijian Zhong, Amy Ockleton, Feng Jiang, Renhui Yi, Shaochun Yang, Ming Li

Peninsula Medical School

Glioblastoma, a highly prevalent and aggressive primary brain tumor, is marked by poor prognosis due to the blood-brain barrier and chemoresistance, which limit conventional pharmacotherapy. Recent research has pivoted toward targeting the tumor microenvironment, where tumor-associated macrophages (TAMs) drive gliomagenesis and malignant progression through immunosuppressive signaling. Small-molecule agents targeting TAMs have emerged as promising therapeutics, capable of reprogramming macrophage polarization, modulating immune cell dynamics, and suppressing glioma growth. This review explores the mechanistic roles of TAMs in glioma and evaluates how small-molecule compounds exert antitumor effects via TAM modulation. These insights lay a foundation for developing next-generation TAM-targeted therapies, offering …

Three Christmas Island Land Crabs Do Not Alter Extracellular Magnesium In Response To Acute Reduced Temperature, Katie N.G. Thiessen, Helena C. Reinardy, John I. Spicer, Lucy M. Turner

School of Biological and Marine Sciences

Magnesium is essential to numerous biological processes in many species. Including protecting intracellular pH and ATP concentrations during temperature and anoxia stress. Extracellular [Mg²⁺] is tightly regulated in many, but not all crustaceans. There is evidence that extracellular [Mg²⁺] content may be open to environmental influence such as temperature. The alteration of extracellular [Mg²⁺] in decapod crustaceans in response to temperature has been proposed, with individuals exposed to low temperature often displaying an increase in extracellular [Mg²⁺]. However, data, supporting or refuting this hypothesis, are sparse and drawn mainly from temperate and …

On The Edge Of Science?: Commentary On Birch On Edge Of Sentience, Mark Briffa, Lynne U. Sneddon

School of Biological and Marine Sciences

In The Edge of Sentience, Jonathan Birch (2024) provides a thought-provokingsynthesis of current perspectives on animal (and artificial) sentience. He addresses the question from conceptual, ethical, regulatory and empirical viewpoints. Here we focus on some of the scientific issues raised, including defining and operationalising the concept of sentience and the implications for policy and regulation. Despite unresolved conceptual challenges, the book makes a compelling case for the continued scientific investigation of animal sentience.

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 …

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. …

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 …

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 …

Defining Consensus‐Based Components For Integrating Dietitians Into Primary Dental Care For Paediatric Populations: A Delphi Study, Lauren Hallewell, Raul Bescos, Zoe Brookes, Robert Witton, Patricia Casas‐Agustench

School of Health Professions

Background: Diet is a modifiable risk factor linking oral and systemic health, contributing to dental caries and weight-related outcomes (including underweight, overweight and obesity) in the paediatric population. However, dietary advice provided by dental professionals in primary dental care is often brief and sugar-focused, representing a missed opportunity to address shared risk factors. Integrating dietitians into primary dental care may support more holistic paediatric preventative care. Objective: To develop expert consensus on the components required to integrate dietitians into primary dental care to address diet as a common risk factor in paediatric oral health and weight-related outcomes. Methods: A three-round …

Presence And Characteristics Of Plastics And Microplastics On The Seabed Of The Western English Channel, Faye Read, Andrew Turner

School of Geography, Earth and Environmental Sciences

Little is known about the presence, distribution, origins and characteristics of plastic litter and microplastics on the ocean floor. In this study, plastics trawled from the bed of the western English Channel have been categorised and analysed by a variety of optical and spectroscopic techniques. A total of 90 plastic samples were classified, in descending order of abundance, as food-drink packaging, unknown, homeware, military and fishing. Most samples showed varying degrees of weathering (e.g., discolouration, distortion, cracking, fragmentation) and were visibly fouled by calcareous deposits. The majority of samples were constructed of polymers of negative buoyancy (e.g., polyamides, polyethylene terephthalate …

Numerical Study Of Air Vents Influence On Wave Forces Acting On Box-Type Bridge Girders With Cavities Under Storm Surge, Khalida H. Jihad

UNF Graduate Theses and Dissertations

Along with the continuous rise of sea level, direct interaction between elevated coastal structures, such as coastal bridges, and seawater during storm surge, has been shown to potentially cause bridge failures in the past. For example, Hurricane Irma (2017) generated storm surge levels exceeding 2-3 m in portions of South Florida, causing widespread transportation disruption including roadway washouts, erosion, and bridge approach damage along US-1 in Florida Keys. Similar failures have occurred during Hurricane Ivan (2004), where uplift forces displaced spans of the Escambia Bay Bridge, and Hurricane Ian (2022), which caused partial collapse of the Sanibel Causeway when elevated …

Exploring The Lived Experiences Of Families Of Students With Significant Disabilities In Accessing Community Transition Supports In Rural Settings, Michael David Green Jr.

UNF Graduate Theses and Dissertations

The transition process beyond high school can be daunting for students with disabilities and their families. Families often encounter difficulties accessing community-based supports after students leave the K–12 education system despite federal legislative mandates under the Individuals with Disabilities Education Act (IDEA) and the Workforce Innovation and Opportunity Act (WIOA). Rural contexts further complicate the experience for families accessing adult services after high school. The current hermeneutic phenomenological study explored how families of students with significant disabilities experienced accessing community transition supports after leaving high school in rural contexts. Through the lens of van Manen’s hermeneutic phenomenology, the study explored …

Development And Testing Of A Low-Cost Inertial Impact Sensor, Gabriel Michael Pesek

UNF Graduate Theses and Dissertations

Acceleration sensors have seen increasing usage within sports to detect when somebody receives an impact to their head which can potentially lead to Traumatic Brain Injury (TBI). While adoption of these sensors has steadily risen, the cost of these sensors is often cited as a reason they have not been as widely adopted, especially for amateur teams. This leads to the need for a lower-cost option for detecting these impacts. To fill this gap, a low-cost, lightweight acceleration sensor was designed that exploits the inertia of a working fluid on impact in order to rupture a metallic membrane which acts …

Integrating Inquiry, Peer Observation, And Professional Learning Communities: Teachers’ Experiences With A Job-Embedded Professional Learning Design, Tiffany Outman

UNF Graduate Theses and Dissertations

Professional learning is often experienced through disconnected initiatives that limit opportunities for sustained collaboration, reflection, and instructional growth. This qualitative action research study explored teachers’ experiences with the integration of teacher inquiry, peer observation, and professional learning communities (PLCs) as a design for job-embedded professional learning within an elementary school setting. The study emerged from an existing culture of collaboration and peer observation at Timber Oaks Elementary, a suburban elementary school in Northeast Florida, and examined what happened when inquiry was intentionally integrated into those structures as the next stage of the school’s professional learning journey. While the professional learning …

Suspended Futures: Exploring The Lived Experiences Of Black Adult Males Affected By Exclusionary Discipline, Tamara Jones

UNF Graduate Theses and Dissertations

Black males continue to experience exclusionary discipline at disproportionately high rates in American schools, often resulting in academic disruption and long-term educational and social consequences. While existing research had extensively documented disciplinary disparities, less attention had been given to how Black males interpret and make meaning of these experiences over time. This hermeneutic phenomenological study explored the lived experiences of Black adult males who experienced exclusionary discipline during their secondary school years and examined how they now make sense of those experiences in adulthood. Grounded in Critical Race Theory and Social Cognitive Theory, the study focused on participants’ perceptions of …

The Composition Of Gases From A Diffusion Flame Above Longleaf Pine Needle Fuel Beds, David R. Weise, Thomas H. Fletcher, Timothy J. Johnson, Weimin Hao, Russell G. Tonkyn, Catherine A. Banach, Javier Palarea-Albaladejo, Mahsa Alizadeh, Stephen Baker

Faculty Publications

The gas and tar composition of a wildland fire diffusion flame from longleaf pine needles is currently relatively unmeasured and more data are needed to fill in the gap between pyrolysis data and smoke plume data, thus improving physical and chemical modeling of wildland smoke formation. A pilot experiment to measure light gas and tar composition of such a flame is described for three flame zones: persistent flame (flame base), intermittent flame, and smoke plume. Flame gases from 24 experimental fires were collected in canisters and analyzed for CO2, CO, H2, CH4, and C2 to C7 hydrocarbon gases. Other light …

Do Cohort Restatements Generate Contagion? A Re-Examination, Melissa F. Lewis-Western, Timothy Seidel, Michael S. Wilkins

Faculty Publications

Gleason, Jenkins, and Johnson (2008) provide evidence that restatements lead to stock price declines among non-restating industry peer firms, suggesting that investors perceive contemporaneous manipulation within the industry. In contrast, Kedia, Koh, and Rajgopal (2015) find that restatements—especially less severe ones—encourage peer firms to initiate earnings manipulation. These divergent findings, together with the rising prevalence of less severe restatements and advances in monitoring technologies, motivate a re-examination of manipulation contagion. Although we are able to replicate the results of both seminal studies, we find that the results in Kedia, Koh, and Rajgopal (2015) are sensitive to design choices that affect …

Psychological Distance And Auditor Assessment Of The Severity Of An Internal Control Deficiency, Scott C. Jackson, John D. Keyser, Douglas F. Prawitt

Faculty Publications

Auditors often underestimate the severity of internal control deficiencies, particularly when associated misstatements are immaterial. We find that auditors are more likely to correctly classify a material weakness when no misstatement information is provided than when misstatement information is available, and that this finding may unconsciously arise from auditors’ construal level in judging control deficiency severity. Through a series of experiments, we manipulate misstatement information related to an internal control deficiency designed to represent a material weakness. We hold the size of potential misstatement constant and find that auditors and graduate auditing students are less likely to correctly assess the …

Influence Of Surface Features On Heat Transfer During Dropwise Condensation Over Superhydrophobic Surfaces In Shear Flow, Shaur Humayun, R. Daniel Maynes, Julie Crocket, Brian D. Iverson

Faculty Publications

This study investigates heat transfer during dropwise condensation (DWC) on superhydrophobic (SH) surfaces in humid air shear flow, emphasizing the effect of increased drop mobility and the influence of surface micro/nanostructure on heat transfer rates. Experiments were conducted on smooth hydrophobic, microstructured SH, nanostructured carbon-infiltrated carbon nanotube (CICNT) surfaces, and two-tiered SH surfaces with both micro and nanostructures. Heat transfer rates were measured under humid air flow rates in the range of 2–4 CFM. Experimental results demonstrate that surfaces with nanostructure (including two-tiered structures) exhibit increased drop mobility and coalescence-induced drop jumping, enhancing drop removal rates and overall heat transfer …
