School of Geography, Earth and Environmental Sciences
Background: Childhood adversity is multi-layered, extending beyond the family to include broader neighbourhood and health contexts. We aimed to investigate how these multiple layers of childhood adversity relate to the risk of death in young adulthood. Methods: Children were followed from birth into young adulthood (16–42 years) using nationwide register data on multi-layered childhood adversity and mortality. Individual adversity included perinatal adversity (preterm or small-for-gestational-age) and mental and physical health-service use. Family adversity included five distinct groups using group-based multi-trajectory modelling based on 12 adversities. Neighbourhood adversity included material deprivation in small-area geographical zones. We evaluated associations of these layers …

School of Engineering, Computing and Mathematics
Life Cycle Assessment (LCA) is a methodology for the evaluation of the (relative) potential environmental impacts of a product system throughout its life cycle. It is standardised under the ISO14040 and ISO14044 series. When conducted rigorously, LCA provides a quantitative framework for comparing environmental impact and can challenge or substantiate common assumptions regarding environmental performance of the system. However, it is essential that any reported results are read in combination with the defined goal and scope, as the choice of the system boundary and/or the allocation of burdens and other methodological choices can influence the outcome presented. This review will …

The Effect Of Face Masks On The Perception Of Trustworthiness And Competence In Individuals With Autistic Traits, Farid Pazhoohi, Maryam Rostami-Aghoui, Leilani Forby, Keina Aoki, Alan Kingstone
School of Psychology
Facial expressions play a crucial role in social communication, influencing judgments of trustworthiness and competence. While previous research has examined how face masks affect trust and competence in general populations, little is known about their impact on individuals with high autistic traits, who often rely more on the mouth region for social cue interpretation. The present study investigates the effects of face masks on perceptions of trustworthiness and competence as a function of high and low autistic traits. Results show that masked faces are generally perceived as more trustworthy and competent than unmasked faces. The effect of mask wearing on …

Height From The Ground And Phytotelm Ph Affect Prokaryotic Diversity In Epiphytic Bromeliads, X O’Reilly-Berkeley, Thomas Hughes, H Mossman, Jennifer Rowntree, Richard Preziosi
School of Biological and Marine Sciences
Tank bromeliads in the neotropics harbour complex communities of invertebrates and even provide food, water and shelter to various vertebrate species. However, few studies have sequenced the microbial communities within epiphytic bromeliad phytotelmata. We sequenced the 16S rRNA subunit extracted from swabs rubbed at the base within the central phytotelm of the epiphytic bromeliads Aechmea hoppii and A. nidularioides. We tested factors that we suspected could influence the alpha diversity and beta-diversity of prokaryotic communities in bromeliads. Height on the tree and size of the bromeliad influenced the alpha-diversity within plants. Height from the ground and pH of the phytotelm …

Focused ultrasound can be delivered through the temporal window to modulate heterogeneously located brain areas. Acoustic simulations allow for safety assessments when dynamically targeting brain structures, but the mismatch between simulation and measured focal pressure can vary across the steerable range due to mechanically inaccurate assumptions made about the skull and transducer. Here, we describe efficient methods for simulation-measurement calibration using axisymmetric projections and sparse sampling across a 3D steerable subspace encompassing deep brain targets across 157 subjects. To address the simulation-reality mismatch in skull transmission, we used the measured and predicted pressure values through eight human temporal window fragments …

Considering Participatory Illustration Forlgbtq+ Inclusion In Climate Discussions: Transformative Learning Theory And Identity: Imagining Sustainable Developments, Discussing Education Futures, Devon Tipping
School of Law, Humanities and Social Sciences
Historically climate discussions have been influenced by dominant discourses that frequently overlook intersectional perspectives. To address this, this article explores how participatory illustration, as a process for listening, reflecting, and co-creating meaning, can enable individuals to consider alternative perspectives on climate discussions in inclusive and transformative ways. As a form of artistic research, illustration moves beyond visual representation to prioritise community-driven strategies for fostering climate solutions and amplifying marginalised voices. This research, formed of five participatory illustration-led workshops with LGBTQ+ individuals in the South-west of England, sought to explore how participatory illustration can foster inclusive climate discussions. Drawing upon transformative …

An Intelligent Systems Explanation Of Type 2 Diabetes And A Narrative To Promote Lifestyle Change, Michael E. Hyland
An Intelligent Systems Explanation Of Type 2 Diabetes And A Narrative To Promote Lifestyle Change, Michael E. Hyland
School of Psychology
Type 2 diabetes is an error in the glycemic control system caused by insulin resistance. Self-organizing control systems use artificial intelligence to monitor and correct how they function and are used in modern applications of robotics. The development of type 2 diabetes is gradual and reversible through lifestyle changes, and this is consistent with insulin resistance being formed through a self-organizing or intelligent control system rather than the traditional control system on which current biomedical control systems are modelled. Lifestyles that induce high levels of glycemic variation would, in an intelligent control system, be detected as excessive oscillation, and an …

New And Emerging Drug Therapy In Primary Open-Angle And Normal-Tension Glaucoma: Pharmacology, Neuroprotection And The Endpoint Problem, Stephanie Mroczkowska, Leanne Smewing, Doina Gherghel
School of Health Professions
Glaucoma is a group of progressive optic neuropathies characterized by retinal ganglion cell (RGC) loss, optic nerve head damage and corresponding visual-field loss. Intraocular pressure (IOP) is the principal modifiable risk factor, and lowering IOP remains the only treatment approach that has been shown in randomized clinical trials to slow glaucomatous progression, including in normal-tension glaucoma (NTG). However, IOP reduction does not eliminate progression in all patients, indicating that susceptibility to pressure-related damage is heterogeneous and that additional biological mechanisms are relevant. This review examines current and emerging pharmacological strategies for IOP lowering, approaches intended to protect RGCs independently of …

A Proposed Methodology For Defining The Criteria Of ‘Good Environmental Status’ For Artificial Light At Night In Marine Waters, Thomas Davies, Olivia R. Rendón, Benjamin O'Driscoll, Rosalyn Seddon, Elena Maggi, Francesca Rossi, Junio Fabrizio Borsani, Tim Smyth
School of Biological and Marine Sciences
There is now a growing recognition internationally that the impacts of Artificial Light at Night (ALAN) on marine biodiversity require regulation. How ALAN should be regulated and what constitutes ‘Good Environmental Status’ (GES) for underwater ALAN remain open questions that if resolved would accelerate the integration of ALAN management into existing policy instruments. In the European Union, interpretations of Descriptor 11 of the Marine Strategy Framework Directive (MSFD) - ‘Introduction of Energy’ - have historically focused exclusively on underwater noise. As a result, no formal targets, thresholds or assessment structures currently exist for marine light pollution across EU Member States. …

Soundscapes are receiving increasing attention in tourism studies. Much focus is given to noise generated by tourism, whereas the role of sound in experiences of place has received less attention. To address this gap, we introduce a ‘soundscape wheel’ as a theoretical and applied tool that can inform transdisciplinary work across tourism studies. The aim of this conceptual map is to discern the ways soundscapes are addressed in the literature spanning natural sciences, social sciences, and humanities, with the hope of better informing tourism geographers’ engagement with sound and other sensorial elements of place. This conceptual map was derived by …

Perspectives On Person‐Centred End‐Of‐Life Care In Care Homes: Findings From A Qualitative Secondary Analysis, Gary Hodge, Susie Pearce
School of Nursing and Midwifery
Background: The number of older people dying in long-term care facilities (LTCF) is growing globally. This highlights an urgent need for high-quality and person-centred palliative and end-of-life care (PEoLC) to be incorporated in LTCFs’, such as care homes. Resident health and care complexities can lead to challenges around PEoLC decision-making and delays in pre-death discussions, ultimately impacting on a care home’s ability to provide a ‘good death’ for the resident and those caring for them. Aim: We aimed to explore what good person-centred end-of-life care might look like in a care home from the perspective of residents, family members and …
A Folk Taxonomy Of Magic, Gustav Kuhn, Cyril Thomas, Griffiths Thomas
A Folk Taxonomy Of Magic, Gustav Kuhn, Cyril Thomas, Griffiths Thomas
School of Psychology
Magic tricks provide a uniquely powerful window onto the boundaries of what people consider possible, and the ways in which those boundaries can be challenged. Although there exists an effectively infinite variety of magic tricks, relatively little is known about how different magical effects relate to one another at a psychological level. Previous attempts to classify magic have largely relied on the judgments of a small number of expert magicians, rather than capturing people’s intuitive understanding of magical phenomena. Here, we introduce a new multi-dimensional taxonomy of magic that treats the observable effect (e.g., an object vanishing) and the attributed …

Operationalising Equity In Ecosystem-Based Fisheries Management, Riley Bibaud, Tom Mullier, Matthew Ashley, Holly Niner, Lauren Stewart, Siân Rees
School of Biological and Marine Sciences
Equity is increasingly recognised as a critical dimension of sustainable ocean governance, yet operational frameworks for incorporating equity considerations into marine governance remain limited. Fisheries management practices have traditionally concentrated on stock sustainability and commercial extraction, often without fully addressing the broader ecosystem dynamics that underpin fish populations throughout key life stages. This study explores how Ecosystem-Based Fisheries Management (EBFM) can support more equitable outcomes by applying a beneficiary-centric natural capital framework to the Celtic Sea and Western Channel Pelagic Fisheries Management Plan. A typology of beneficiaries was developed to assess the distribution of ecosystem service benefits, followed by a …

School of Biological and Marine Sciences
Rubble strips are shore-normal, elongated deposits on coral reef flats, composed of variably sized and shaped mobile coral clasts, which can contribute to the sediment supply on exposed low-lying coral reef islands. As climate change-driven ecological and physical disturbances increasingly impact coral reef systems and associated landforms, understanding the processes and controls governing their morphodynamics is critical. At an exposed intertidal rubble strip in Huvadhu Atoll, we examined: i) the morpho-sedimentological characteristics; ii) short-term (days-weeks) clast mobility using tracer experiments with in situ current and wave measurements; iii) intra-annual morphological changes using repeated UAV photogrammetric surveys; and iv) deposit age …
Camouflaging Autistic Traits Is Not A Consequence Of Conformist Tendencies, Alastair Smith, Rhiannon Walsh
Camouflaging Autistic Traits Is Not A Consequence Of Conformist Tendencies, Alastair Smith, Rhiannon Walsh
School of Psychology
Social camouflaging behaviours are often used by people with high autistic traits to negotiate a predominantly neurotypical social world. Previous discussion has associated camouflaging with a tendency to conform, although it has also been suggested that masking autistic tendencies may be a more specific motivating factor. The relationship between autistic traits and conformity is itself equivocal, suggesting that it may not necessarily be a driving force for social camouflaging in this group. To better characterise the relationship between these factors, we conducted an exploratory questionnaire study comprising measures of social conformity (Tendency to Conform Questionnaire), autistic traits (AQ), social camouflaging …

Shallow Margin Fish Biomass Estimates In Lake Victoria Using Horizontal-Beam Acoustics, Yang Yang, Roland Proud, Robert Kayanda, Collins Ongore, Mboni Elison, Hillary Mrosso, Benedicto B Kashindye, Andrew S Brierley, Alina M Wieczorek
School of Biological and Marine Sciences
The shallow margins (<10 m depth) of Lake Victoria, comprising ca. 9% of the lake’s total area, have been suggested to harbour up to 35% of the lake’s fish biomass based on limited trawl data. However, since standardized lake-wide acoustic surveys began in 1999, these nearshore waters have remained inadequately sampled due to the inability of research vessels to operate in shallow waters, creating one of the largest data gaps in the assessment of Africa’s most productive inland fishery. This study addresses this longstanding sampling gap by conducting near-horizontal acoustic surveys at 17 sites along the Tanzanian shoreline. A total of 65 surveys over 6 rounds were conducted between November 2019 and March 2023, using an open canoe equipped with a broadband echosounder (Simrad EK80, centre frequency 200 kHz). Concurrent beach seine and gillnet sampling provided species composition and size information, and biomass was estimated using echo counting and geostatistical methods. Shallow margins cover ca. 10.2% (3528 km²) of the Tanzanian sector within the 10 m isobath and 19.5% (6736 km²) within the 20 m isobath. Estimated total biomass ranged from 0.26 to 0.68 million tonnes (MTs) in the 20 m strip and from 0.15 to 0.37 MTs in the 10 m strip. Tilapia and haplochromines dominated the biomass in most surveys, while Nile perch contributed a smaller but persistent fraction. These findings identify the shallow margins as a quantitatively important biomass domain in the Tanzanian sector and highlight the need for dedicated shallow water sampling in future fisheries assessment and ecosystem modelling.

Amphibian populations are declining, and species are going extinct due to habitat loss, climate change, and emerging infectious disease, prompting the increasing use of translocations as a conservation tool. Skin-associated bacterial communities play a key role in amphibian health, particularly in protecting hosts from pathogenic infection. However, to date weknow relatively little about the impact of translocation on the dynamics of skin-associated bacteria, or the consequences oftranslocation-mediated disturbance of the microbiome for amphibian health. We investigated the skin microbiome of the critically endangered frog Craugastor ranoides, now restricted to a fraction of its historical range in Costa Rica. We first …

School of Biological and Marine Sciences
Many ocean sediment habitats on the continental shelf have been extensively trawled and dredged with bottom-towed fishing gear before scientific baselines of the seabed could be recorded. Observations of ocean sediments may reflect shifted baselines towards more mobile and homogenous environments, dominated by disturbance-tolerant, short-lived species. This will have implications for the appropriateness of existing Marine Protected Area (MPA) management. Low levels of trawling and dredging in the Isles of Scilly provide an opportunity to study a UK example of minimally impacted sediment habitats, where absence of bottom-towed fishing since 2013 has provided the chance for 10 years of ecological …

School of Biological and Marine Sciences
Accumulation of end-of-life plastic is a global environmental problem. Plastics are widely used in oil and gas infrastructure and bring considerable benefits while in service. However, the environmental consequences of end-of-life decommissioning scenarios are largely unknown. Using the UK Continental Shelf (UKCS) as a case study we estimate the mass of plastics deployed in subsea pipelines, quantify degradation and estimate the rate of microplastic generation. Recognising that the relatively slow rate of any subsequent mineralisation leads to an accumulation of plastic particles in the marine environment, we then apply a novel approach using Predicted No-Effect Concentration (PNEC) analysis to estimate …

First Direct Observations Of Dilute Antarctic Turbidity Currents Associated With Dense Water Overflows, Corbyn Johannes, Jess Hilman, Phil Hosegood, Ed Pope, Katherine Maier, Jenny Gales
School of Biological and Marine Sciences
Turbidity currents are increasingly recognised as a key mechanism for transporting sediment into the deep ocean, yet their structure, behaviour, and long-term impact in Antarctic submarine canyons remain poorly understood owing to a lack of direct observations. Using a year-long mooring deployed in Wilson Canyon, western Ross Sea, we obtained the first in situ measurements of a dilute turbidity current associated with a slow moving dense water overflow in Antarctica, documenting a single event that lasted for thirteen days and exhibited a distinct internal structure: a dense frontal head containing coarse sediment and cold, saline shelf-derived water, followed by a …

As climate change intensifies, cultivating hope has become critical for sustaining possibilities and collective action. However, existing scholarship on hope remains predominantly Eurocentric and theoretical, offering limited empirical attention to how hope is generated and sustained through everyday actions in the Global South. This paper addresses this gap by examining four grassroots initiatives in the Philippines engaged in environmental advocacy, post-disaster recovery, youth empowerment, and speculative design. Drawing on fieldwork conducted between 2017 and 2024 and guided by the framework of radical hope, we analyse how a climate politics of hope is enacted in practice. Our findings reveal three dynamics …

Regulation Of Ultradian Pulsatility And Stress Responses In The Human Hypothalamic–Pituitary–Adrenal Axis, Belinda Lombard, Thomas J. Upton, Ben Gibbison, David Henley, Georgina Russell, John R. Terry, Stafford L. Lightman, Eder Zavala
Peninsula Medical School
The hypothalamic–pituitary–adrenal (HPA) axis is a vital neuroendocrine system that maintains homeostasis by regulating stress hormone secretion through tightly controlled circadian and ultradian rhythms. Although rodent studies and mathematical models have clarified the mechanisms of ultradian pulsatility, a quantitative, human-specific description of HPA axis dynamics is lacking. Here, we analyse 24-h high-frequency hormonal profiles from a cohort of healthy humans to quantify inter-individual variability in adrenocorticotropic hormone and cortisol rhythms and to calibrate a foundational mathematical model of the human HPA axis. The model reproduces key human-specific features, including an asymmetric circadian rhythm peaking at waking and ultradian oscillations with …
