The Mythology Of Polymyositis, Suur Biliciler, Tahseen Mozaffar

Faculty, Staff and Student Publications

Polymyositis (PM) has been in the diagnostic armamentarium in medicine since the mid-nineteenth century. Medicine training puts a heavy emphasis on this diagnosis, and anyone with proximal muscle weakness with elevated serum creatinine kinase is assumed to be PM and a number of patients were rendered this diagnosis without additional testing. This article addresses the historical aspects of the diagnosis of PM and its evolution. We review this literature that addresses the rarity of this diagnosis and rightly puts in perspective in terms of its occurrence in relation to other inflammatory myositides.

Catch Me If You Can: Microplastics Hidden In Plain Sight, Karin Mattsson, Pere Masque, Thomas Maes, Marc Metian

Research outputs 2022 to 2026

Microplastic (MP) pollution is widely recognised as a pressing environmental issue, yet certain major sources remain under-addressed. This paper focuses on three significant but often overlooked contributors: paint particles, textile fibres, and tire wear particles (TWP). Together, these sources account for over 25 % of global MP emissions, nearly 3 million tonnes annually, yet they are rarely singled out in research or regulation. Each presents unique analytical and regulatory challenges due to their complex compositions, diffuse emissions, and strong ties to daily life. We enumerate current knowledge on their environmental pathways, emission estimates, and detection methods, highlighting the need for …

Artificial Intelligence To Detect Developmental Dysplasia Of Hip: A Systematic Review, Suketu Bhavsar, Bhanu B. Gowda, Maulini Bhavsar, Sanjay Patole, Shripada Rao, Chandra Rath

Research outputs 2022 to 2026

Aim: Deep learning (DL), a branch of artificial intelligence (AI), has been applied to diagnose developmental dysplasia of the hip (DDH) on pelvic radiographs and ultrasound (US) images. This technology can potentially assist in early screening, enable timely intervention and improve cost-effectiveness. We conducted a systematic review to evaluate the diagnostic accuracy of the DL algorithm in detecting DDH. Methods: PubMed, Medline, EMBASE, EMCARE, the clinicaltrials.gov (clinical trial registry), IEEE Xplore and Cochrane Library databases were searched in October 2024. Prospective and retrospective cohort studies that included children (< 16 years) at risk of or suspected to have DDH and reported hip ultrasonography (US) or X-ray images using AI were included. A review was conducted using the guidelines of the Cochrane Collaboration Diagnostic Test Accuracy Working Group. Risk of bias was assessed using the QUADAS-2 tool. Results: Twenty-three studies met inclusion criteria, with 15 (n = 8315) evaluating DDH on US images and eight (n = 7091) on pelvic radiographs. The area under the curve of the included studies ranged from 0.80 to 0.99 for pelvic radiographs and 0.90–0.99 for US images. Sensitivity and specificity for detecting DDH on radiographs ranged from 92.86% to 100% and 95.65% to 99.82%, respectively. For US images, sensitivity ranged from 86.54% to 100% and specificity from 62.5% to 100%. Conclusion: AI demonstrated comparable effectiveness to physicians in detecting DDH. However, limited evaluation on external datasets restricts its generalisability. Further research incorporating diverse datasets and real-world applications is needed to assess its broader clinical impact on DDH diagnosis.

Bravo, Júlia Rodriguez-Puig, Aaron Alorda-Kleinglass, Carlos Green-Ruiz, Marc Diego-Feliu, Pere Masqué, Javier Gilabert, Jordi Garcia-Orellana

Research outputs 2022 to 2026

Coastal enclosed ecosystems, such as lagoons, are vulnerable to anthropogenic impacts because they favor the accumulation of contaminants from the surrounding watersheds, particularly in their sediments. Europe's largest saltwater lagoon, the Mar Menor (SE, Iberian Peninsula), is a highly impacted ecosystem and the first in the continent to be granted personhood rights. Based on a high-resolution spatial and temporal dataset, we present the historical reconstruction of metal contamination in this ecosystem during the last century. Our results highlight that sediment metal contamination has been mainly driven by the development of the mining industry in the nearby Sierra Minera de Cartagena-La …

Reading The Word And The World: Overstanding Literacy In Aboriginal And Chinese Classrooms, Gui Ying Annie Yang-Heim

Faculty Publications - College of Education

This qualitative comparative case study examines how culturally grounded philosophies of education shape the teaching and learning of reading in two cross-cultural contexts—an Aboriginal Australian classroom and urban Chinese elementary schools. Drawing on interpretive and reflexive methodologies, it investigates how Aboriginal and Confucian epistemologies influence literacy practices and how these practices align with or resist dominant, decontextualized models of reading instruction. Data sources include classroom observations, reading assessments, teacher interviews, and researcher reflections. Conceptually framed by Gadamer’s hermeneutics, Bourdieu’s theory of cultural capital, Habermas’s typology of knowledge, and the Caribbean concept of overstanding, this research finds that Aboriginal literacy is …

Influence Of Organic Matter And Mineral Composition On Carbonate Source Rock Wettability: Implications For Co2 Geostorage, Muhammad Usman, Nurudeen Yekeen, Muhammad Ali, Mujahid Ali, Alireza Keshavarz, Stefan Iglauer, Volker Vahrenkamp

Research outputs 2022 to 2026

Wettability is critical in determining carbon dioxide (CO2) behavior during geological sequestration in unconventional reservoirs. Unconventional reservoirs are compositionally heterogeneous, affecting CO2 plume migration, containment security, and storage capacity during geological sequestration. Previous studies on CO2 storage in unconventional reservoirs have primarily attributed to changes in organic matter content; however, this study examines how variations in the mineralogical and organic matter content combined affect wettability in CO2/brine systems under subsurface conditions. Three samples with varied mineralogy and TOC content were selected from a well drilled in Jordan source rocks—an immature analog of marine-derived, carbonate-dominated, Type IIS source rocks. Samples were …

Technology Discontinuance: A Systematic Literature Review And Research Agenda, Birgit Altrichter, Sabine Benoit

Research Collection Lee Kong Chian School Of Business

Technology discontinuance by users who quit digital services such as social media or lose interest in their devices after a few weeks is a common phenomenon. Yet it has received little research attention; the few studies that address it are scattered across disciplines. Research into customer churn is more prevalent, but it implies switching providers rather than halting usage altogether. By moving beyond discipline-based knowledge boundaries and conducting a systematic literature review, the current article proposes a technology discontinuance framework, which details seven technology discontinuance types (overuse, overload, proficiency, disenchantment, social, circumstantial, and solution) and their drivers. For example, guilt …

Managing The Personalization Paradox: Lessons From Spotify’S Ai Dj, Anirban Mukherjee, Hannah H. Chang, Jonathan Wibowo

Research Collection Lee Kong Chian School Of Business

This case study uses Spotify’s AI DJ to examine the “personalization paradox,” where product features designed to deepen user connection can instead cause alienation. An analysis of over 1,400 user comments identifies three core frictions: a perceived loss of user agency, mismanaged expectations for the human-like AI, and a scalability bottleneck that led to repetitive content. Students are placed in the role of a product manager tasked with developing a prioritized roadmap to address these issues, forcing them to grapple with the critical trade-offs between technological capability and user psychology.

Determining The Accumulation Potential Of Nanoplastics In Crops: An Investigation Of 14C-Labelled Polystyrene Nanoplastic Into Radishes, Nathaniel J. Clark, Astrid C. Fischer, Demelza Carne, George R. Littlejohn, Lee J. Durndell, Anne Plessis, Richard C. Thompson

School of Biological and Marine Sciences

The capacity of crops to accumulate nanoplastics has remained relatively unexplored largely due to analytical constraints. To address this challenge, the present study employed a radiolabelling approach to demonstrate, for the first time, that polystyrene nanoplastics (¹⁴C-PS NPs) accumulate and move into the edible tissues of radishes (Raphanus sativus). Radishes were exposed hydroponically for five days, with only their non-fleshy roots in contact with the ¹⁴C-PS NPs, while accumulation in the fleshy (edible) roots and shoots was subsequently measured. The radish roots retained nearly 5 % of the ¹⁴C-PS NPs from the exposure, either through accumulation …

Plastic Or Natural? The Impact Of Marine Debris On The Shell Preference Of A Terrestrial Hermit Crab, Robert Puschendorf, Pete Cotton, Mark Briffa

School of Biological and Marine Sciences

Plastic pollution is one of the main human-induced rapid environmental changes threatening marine organisms. Terrestrial hermit crabs, which inhabit coastal areas where litter accumulates, are increasingly documented using plastic debris as shells, and a recent study hypothesized that this shift may be an adaptive response. They suggested that ‘plastic shells’ may reduce transport costs, provide camouflage in a polluted environment, and may even be favoured by sexual selection. Our study is the first to quantify plastic shell use in a population, to examine shell preference and to test the hypothesis that plastic shells optimize the ratio of weight to volume. …

The Root Cause Of Perceived Appraisal Politics Using Evidence From The South Korean Public Sector, Jinwoong Yoo, Saeyeon Roh, Mohamed Haddoud, Smita Tripathi

Plymouth Business School

The purpose of this study is to investigate the root causes of Perceived Appraisal Politics (PAP) within the public sector in South Korea. Scholars in the field of Human Resource Management (HRM) have identified the determinants of PAP in an effort to mitigate it. However, the complex interactions among those determinants and root causes have been overlooked. Therefore, we adopt a novel methodology in this study that combines Interpretive Structural Modelling (ISM) and fuzzy-Decision-Making Trial and Evaluation Laboratory (f-DEMATEL). The findings indicate that the root causes of PAP include the presence of cliques, ambiguity of appraisal policies and goal ambiguity …

School of Geography, Earth and Environmental Sciences

Tritium (³H), an isotope of hydrogen, is a by-product of the nuclear industry. Decommissioning and normal operations of nuclear facilities can generate tritiated stainless-steel particles (T-SSPs) that could be unintentionally released into the environment. Considering tritium's physicochemical properties and the proximity of nuclear facilities to water bodies, assessing the behaviour and potential effects of these particles in the aquatic environment is imperative. In the present study, marine mussels, Mytilus galloprovincialis, were exposed to: (a) hydrogenated, non-radioactive stainless-steel particles (H-SSPs) (10 mg L⁻¹) (b) T-SSPs (1 and 10 MBq L⁻¹) and (c) tritiated water (HTO) …

School of Geography, Earth and Environmental Sciences

Water that flows through permeable ultramafic rocks produces high abundances of molecular hydrogen (H₂), methane (CH₄), and other small organic molecules. Such products can fuel life in the rocky subseafloor, be extracted for energy, and may have played a role in pre-biological chemical synthesis on early Earth or other planetary bodies. The International Ocean Discovery Program drilled a new 1268-m-deep borehole (U1601C) into serpentinized mantle with minor gabbroic rocks on the Atlantis Massif, ∼800-m north of the Lost City hydrothermal field (30°N, Mid-Atlantic Ridge). Measured temperatures of the disturbed borehole reached 91.3 °C, and equilibrated temperatures …
