Background: This systematic review examines the lived experiences of Black students in UK higher education (HE), focusing on their encounters with racism and racial disadvantage, and how institutional and social factors contribute to these experiences. Methods: We conducted a systematic search across seven databases (Academic Search Complete, Education Abstracts, PsycINFO, Race Relations Abstracts, Scopus, Web of Science, and SocINDEX) in April 2023, with periodic updates. The grey literature, which refers to research and information produced outside of traditional academic publishing and distribution channels, was reviewed. This includes reports, policy briefs, theses, conference proceedings, government documents, and materials from organisations, think tanks, or professional bodies that are not commercially published or peer-reviewed but can still offer valuable insights relevant to the topic. Hand searches were also included. Studies were included if they were peer-reviewed, published between 2012 and 2024, written in English, and focused on the experiences of Black students in UK higher education. Both qualitative and quantitative studies with a clear research design were eligible. Studies were excluded if they lacked methodological rigour, did not focus on the UK HE context, or did not disaggregate Black student experiences. Risk of bias was assessed using standard qualitative appraisal tools. Thematic analysis was used to synthesise findings. Results: Nineteen studies were included in the review. Two main themes emerged: (1) diverse challenges including academic barriers and difficulties with social integration, and (2) the impact of racism and institutional factors, such as microaggressions and biased assessments. These issues contributed to mental fatigue and reduced academic performance. Support systems and a sense of belonging helped mitigate some of the negative effects. Discussion: The evidence was limited by potential bias in reporting and variability in study quality. Findings reveal persistent racial inequalities in UK HE that affect Black students’ well-being and outcomes. Institutional reforms, increased representation, and equity-focused policies are needed. Future research should explore effective interventions to reduce the awarding gap and support Black student success Full article

Background: Youth suicide is a global issue and a type of death that can be prevented through early access to evidence-based mental health interventions, which can contribute to improved quality of life as well as health, educational and employment outcomes. Young people are encouraged to seek help for mental health problems, yet help-seeking rates remain low. Objective: The aim of this research was to explore how young people with a mental health problem decide to search and ask for professional help, and the impact of help-seeking experiences. Methods: Young people aged 16–25 years with experiences of help-seeking to mental health services were recruited (N = 18). Data analysis was informed by Constructivist Grounded Theory methods, and the findings were presented across four sub-categories: 1. Deciding to Seek Help; 2. Searching for the Right Help; 3. Reflecting on Help-seeking Experiences; and 4. Living with the Impacts of Help-seeking. Findings: Young people sought help often while highly distressed and required the skills and resources of a family member or friend to access the right type of help. Help-seeking was multi-episodic and had lasting positive and negative impacts. Young people’s help-seeking patterns were found to be similar to the ways in which they problem-solve in learning contexts, and the concept of a formal help-seeking skillset was presented.

Despite rapid progress in natural language processing, current interactive AI systems continue to struggle with interpreting ambiguous, idiomatic, and contextually rich human language, a barrier to natural human–computer interaction. Many deployed applications, such as language games or educational tools, showcase surface-level adaptation but do not systematically probe or advance the deeper semantic understanding of user intent in open-ended, creative settings. In this paper, we present Semantrix, a web-based semantic word-guessing platform, not merely as a game but as a living testbed for evaluating and extending the semantic capabilities of state-of-the-art Transformer models in human-facing contexts. Semantrix challenges models to both assess the nuanced meaning of user guesses and generate dynamic, context-sensitive hints in real time, exposing the system to the diversity, ambiguity, and unpredictability of genuine human interaction. To empirically investigate how advanced semantic representations and adaptive language feedback affect user experience, we conducted a preregistered 2 × 2 factorial study (N = 42), independently manipulating embedding depth (Transformers vs. Word2Vec) and feedback adaptivity (dynamic hints vs. minimal feedback). Our findings revealed that only the combination of Transformer-based semantic modelling and adaptive hint generation sustained user engagement, motivation, and enjoyment; conditions lacking either component led to pronounced attrition, highlighting the limitations of shallow or static approaches. Beyond benchmarking game performance, we argue that the methodologies applied in platforms like Semantrix are helpful for improving machine understanding of natural language, paving the way for more robust, intuitive, and human-aligned AI approaches.

Background: One in seven youth experiences a mental disorder, accounting for 13% of the global disease burden. The family environment is a modifiable factor for the prevention of mental disorders. While evidence-based online parenting programs exist, engagement by immigrant families, such as Indian-origin families in Australia, remains low. Objective: To explore perceived barriers of Indian-origin parents and co-create strategies to build cross-cultural bridging interventions to increase their engagement in parenting programs. Method: A qualitative co-design method was used, and participants were selected using a set of inclusion criteria through a criterion-based sampling approach. Eight videoconference workshops were conducted with 23 Indian-origin parents living across Australia, incorporating scenarios, roleplay, and vignettes. Data were analysed using Braun and Clarke’s inductive coding approach. Results: One central theme and six design principles were developed. The central theme, low engagement with parenting programs, encompassed five factors that contribute to low engagement: ‘parenting programs’ is not a concept in India; limited awareness of parenting programs available in Australia; lack of time to engage in parenting programs; misalignment between parenting program content and real-world parenting challenges; and an ‘I know how to parent’ mindset. The six design principles were: acknowledge culture shock and acculturation; use a collaborative approach; include content specific to immigrant parents and children; adopt cross-cultural perspectives; use short and interactive bilingual pedagogic tools; and use focused dissemination and marketing. Conclusions: This study’s findings formed the foundation for developing a cross-cultural bridging intervention to connect Indian-origin parents with existing online parenting programs. Full article

The explosive growth of tasks on crowdsourcing platforms has intensified information overload, making it difficult for workers to spot lucrative bids; yet mainstream recommenders inherit a user-independence assumption from e-commerce and therefore overlook the real-time competition among workers, which degrades ranking stability and accuracy. To bridge this gap, we propose the Adaptive Parameter Exponential Decay Algorithm (APAED), which first produces base relevance scores with an offline neural model and then injects a competition-aware exponential decay whose strength is jointly determined by the interquartile range of each worker’s score list (global factor) and the live bid distribution of every task (local factor). This model-agnostic adjustment explicitly quantifies competitive intensity without handcrafted features and can be paired with any backbone recommender. Experiments on a real-world dataset comprising 25,643 tasks and 19,735 workers show that APAED cuts the residual RMSE of HR@10 from $9.575\times {10}^{-4}$ to $5.939\times {10}^{-4}$ (−38%) and that of MRR from $2.920\times {10}^{-4}$ to $0.736\times {10}^{-4}$ (−75%), substantially reducing score fluctuations across epochs and consistently outperforming four strong neural baselines. These results confirm that explicitly modeling worker competition yields more accurate and stable task recommendations in crowdsourcing environments. Full article

Background: Anal squamous cell carcinoma is a rare disease strongly associated with the human papillomavirus (HPV) and preceded by the premalignant anal squamous intraepithelial lesion (ASIL). High-resolution anoscopy (HRA) using a colposcope is considered the gold standard for detecting and managing ASIL. Despite being recommended in current guidelines for anal cancer screening, HRA availability remains limited. Although generally well tolerated, concerns about follow-up adherence persist. We have developed an endoscopic technique using high-resolution flexible endoscopes for detection, resection, and screening of ASIL. Our previous research suggests that this method is effective and gentle, but patients’ experiences of this approach remain underexplored. The aim of this study was to explore patients’ experiences of endoscopic detection, treatment, and screening of anal squamous intraepithelial lesions. Method: A qualitative approach was used involving semi-structured interviews and abductive qualitative content analysis. The 32-item COREQ checklist guided the reporting of the study. All participants followed a standardized protocol for treatment and follow-up. Results: Analysis of 16 interviews (female n = 7, male n = 9, age 19–72 years) yielded four categories: a comforting encounter in an exposed situation (with four subcategories); impact on intimate relationships (with one subcategory); living with uncertainty (with four subcategories); and physical discomfort (with two subcategories). Conclusions: High-resolution endoscopy is a well-tolerated and effective diagnostic and therapeutic modality for ASIL. However, the psychological impact of HPV-related conditions highlights the need for appropriate psychosocial support. These findings underscore the importance of integrating patient-centered care principles into the implementation of novel diagnostic and therapeutic technologies. Full article

The island of St Lucia has undergone a dramatic transformation in a matter of decades, metamorphosing from a monocrop banana economy to a high end tourist destination which generates billions of dollars of revenue for those who operate it. This transformation has, however, seen a tourism industry develop that relies on Western models of environmental destruction and degradation. For Rastafari communities in St Lucia this represents a direct challenge to a deeply green ecological ethic which lies at the heart of the movement. Instead, some offer an alternative—eco-tourism. Several Rastafari are today engaged in offering an experience to visitors which brings them closer to this naturality rather than separating them from. To do so, however, is not without challenge. Many Rastafari seek to avoid as far as is possible all forms of engagement with a ‘Babylonian’ system that has persecuted the movement and debased all around it. For these individuals, it is only through the establishment of agrarian communes entirely separate from governmental systems and means of production that Rastafari might achieve a spirituality and a living modality free from corruption. These Rastafari eco-tourism ventures offer an alternative to this vision in presenting a different path to a shared ambition of self-sufficiency. Through ethnographic research on the island this paper seeks to situate and explore Rastafari eco-tourism as a vision for community autonomy in St Lucia. Full article

This paper explores the complexities of measuring impact from placemaking in the context of public and community housing (sometimes known as social or subsidised housing) in Aotearoa New Zealand. Placemaking refers to a range of practices and interventions—including the provision or facilitation of access to community infrastructure—that seek to cultivate a positive sense of place through everyday experiences, spaces, relationships, and rituals. Drawing on interviews with four community housing providers (CHPs), analysis of their documentation, and tenant survey and interview data from two of those CHPs, this research examines providers’ change theories about placemaking in relation to tenants’ experiences of safety, belonging and connectedness, including access to local amenities, ease of getting around, and a sense of neighbourhood and community affiliation. Based on the importance of these variables to wellbeing outcomes, the study highlights the potential of placemaking to support tenant wellbeing, while also recognising that providers must navigate trade-offs and co-benefits, limited resources, and varying levels of tenant engagement. While placemaking can help to foster feelings of connection, belonging and safety, its impact depends on providers’ capacity to initiate and sustain such efforts amidst competing demands and constraints. The study offers indicative findings and recommendations for future research. Although the impacts of placemaking and community infrastructure provision are difficult to quantify, research findings are synthesised into a prototype framework to support housing providers in their decision-making and housing development processes. The framework, which should be adapted and evaluated in situ, potentially also informs other actors in the built environment—including architects, landscape architects, urban designers, planners, developers and government agencies. In Aotearoa New Zealand, where housing provision occurs within a colonial context, government agencies have obligations under Te Tiriti o Waitangi to actively protect Māori rights and to work in partnership with Māori in housing policy and delivery. This underscores the importance of placemaking practices and interventions that are culturally and contextually responsive. Full article

Background/Objectives: Diabetic foot syndrome (DFS) is a chronic complication of diabetes mellitus that negatively impacts patients’ quality of life (QoL). Patients’ perceptions of health status and healthcare can be assessed using Patient-Reported Experience Measures (PREMs) and Patient-Reported Outcome Measures (PROMs). This article aims to review the available literature on PREMs and PROMs, evaluate their characteristics, and determine whether an existing measure is applicable to or can be developed for the patient population of a third-level unit for diabetic foot. Methods: A search through Cinahl, Scopus, and Pubmed electronic databases was conducted to identify studies published between 2000 and 2024. Eligible studies included those using PREMs and PROMs in patients with DFS. Studies that used self-assessment methods or open questions and those that applied PROMs in people living with diabetes without diabetic foot were excluded. Results: After a careful selection, 53 studies met the inclusion criteria: none of these applied PREMs. Regarding PROMs, 46 studies applied a generic method alone or in combination with a specific tool to large populations comparing patient groups, while 7 studies applied a specific PROM alone to small populations evaluating specific aspects of pathology. Conclusions: In the existing literature, generic tools are mainly reported. No gold standard has yet been identified among all the tools considered for assessment of quality of life or patients’ perceptions of their health. Further studies are needed to develop a reliable and specific PREM or PROM questionnaire for complex patients affected by DFS. Full article

Discrimination and harassment (DH) against women are topics of broad concern to gender equality advocates. This study aimed to investigate the prevalence of DH against women in Nigeria, based on seven specific forms of DH captured in the 2021 Nigeria Multiple Indicator Cluster Survey (MICS), and to identify key socio-demographic factors associated with an aggregated DH outcome variable. Drawing upon data from 38,806 women aged 15–49, we used descriptive statistics to summarize the prevalence of DH across seven reasons and the socio-demographic characteristics of respondents, followed by chi-square analysis to test bivariate associations and binary logistic regression to identify predictors. Results showed that the prevalence of DH against Nigerian women (18.9%) was significantly associated with socio-demographic factors such as age, education level, wealth index, marital status, and ethnicity. At the individual level, women who felt very unhappy had higher odds of experiencing DH (OR = 3.101, 95% CI: 2.393–4.018, p < 0.001) compared to those who felt very happy. In contrast, women with higher/tertiary education (OR = 0.686, 95% CI: 0.560–0.842, p < 0.001) were 31.4% less likely to face DH than those with no education. Regionally, respondents living in Zamfara (OR = 5.045, 95% CI: 3.072–8.288, p < 0.001) were over five times more likely to experience DH than those in Kano state. The findings underscore the need for policy interventions and support systems to address DH against women in Nigeria. Full article

Egg yolk immunoglobulin Y (IgY) has significant application potential in aquaculture as passive immunotherapy against various bacterial infections owing to its capacity for large-scale and cost-effective production. In this study, IgY antibodies of live or inactivated Aeromonas veronii were generated by laying hens immunization. Subsequently, passive immune protection experiments of the two IgY antibodies were conducted on goldfish (Carassius auratus) infected with A. veronii and Aeromonas hydrophila. The results indicated that both live and inactivated bacteria IgY antibodies provided significant passive protection rates (p < 0.05). Furthermore, ELISA tests demonstrated that the two IgY antibodies, as well as the serum of C. auratus, interacted with A. veronii or A. hydrophila (p < 0.05) in vitro. The bacterial loads in the kidneys of C. auratus immunized with the two IgY antibodies were decreased (p < 0.05), and C. auratus phagocytes had enhanced phagocytic activity. The expression levels of antioxidant factors (SOD, CAT, GSH-Px) and inflammatory factors mRNA (TNF-α, IL-1β, IL-6, IL-8) were down-regulated (p < 0.05). Additionally, histopathological analysis indicated that the renal, splenic, and intestinal tissue structures remained intact, and the immunofluorescence confirmed that apoptosis and DNA damage factors of p53 and γH2A.X reduced (p < 0.05), respectively. Thus, the IgY antibodies of live and inactivated A. veronii exhibit passive immune-protective effects against different pathogenic bacteria in C. auratus. Further, inactivated A. veronii immunization causes less damage to laying hens than that of live bacteria, which aligns more closely with welfare standards for laying hens, and the IgY of inactivated A. veronii is anticipated as a cross-protection against A. veronii and A. hydrophila infections in aquaculture.

Accessing the built environment poses many challenges for people with disabilities, severely affecting their independence and quality of life. A panel of experts with a lived experience of disabilities co-designed a survey capturing the challenges in New Zealand’s public places. There were 319 survey respondents with impairments related to mobility (66.5%), vision (18.8%), hearing (5.0%), sensory processing and cognition (8.8%). They perceived sports stadiums as the least accessible venue, followed by bars, boutique shops and public toilets. The most accessible venues were supermarkets, libraries and shopping malls. The type of disability affected the main accessibility challenges. Significant outdoor barriers included uneven and cluttered paths, inadequate provision of curb cuts, seating and accessible parking spaces, and obscure wayfinding. Entrance barriers included heavy doors, complex access control, remote ramps and narrow, obscure entrances. Interior problems included cluttered paths and poor signage. The top priorities for improvement were simplifying layouts, keeping paths clear, and providing clear, inclusive signage, communication and assistance for people with varying impairments. Providing lower counters, better colour contrast, hearing loop facilities and better control of lighting and acoustics also improve accessibility. This research contributes novel experiential data from people with disabilities that is critical to achieving an inclusive built environment. Full article

Despite being considering as having infinite fatigue life, failures of motor crankshafts forged from DIN 34CrNiMo6 steels have been reported in Brazilian power plants. As such, the present work aims to discuss the failure of a crankshaft within this context, with the purpose of verifying whether the stresses developed in critical locations of the component were in accordance with the steel’s fatigue limits, as well as if the material exhibits an adequate resistance to crack propagation. Taking into consideration a set of critical-plane stress-based multiaxial fatigue criteria, namely Findley, Matake, McDiarmid and Susmel and Lazzarin, the fatigue behaviour of the material is analysed and discussed. Furthermore, $da/dN$ versus $\mathsf{\Delta }K$ experiments were carried out with the purpose of determining the DIN 34CrNiMo6 steel’s crack growth threshold $\mathsf{\Delta }{K}_{th}$ and comparing it to the $\mathsf{\Delta }{K}_{th}$ of three other commercially available steels (DIN 42CrMo4, SAE 4140 and SAE 4340). The selected multiaxial fatigue criteria indicated that the stresses developed throughout the component were not sufficient to drive the crankshaft to failure, thus indicating safety. On the other hand, the DIN 34CrNiMo6 steel presented the lowest $\mathsf{\Delta }{K}_{th}$ ($6.6\mathrm{M}\mathrm{P}\mathrm{a}{\mathrm{m}}^{1/2}$) among all the considered steels ($10.86$, $12.38$ and $7.22\mathrm{M}\mathrm{P}\mathrm{a}{\mathrm{m}}^{1/2}$ for the DIN 42CrMo4, SAE 4140 and SAE 4340, respectively), therefore being susceptible to shorter fatigue lives in comparison to the other materials.

Motor impairments significantly affect individuals’ ability to perform activities of daily living, reducing autonomy and quality of life. In response to this, robot-assisted rehabilitation has emerged as an effective and practical solution, enabling controlled limb movements and supporting functional recovery. This study presents the development of an upper-limb exoskeleton designed to assist rehabilitation by integrating neurophysiological signal processing and real-time control strategies. The system incorporates a proportional–derivative (PD) controller to execute cyclic flexion and extension movements based on a sinusoidal reference signal, providing repeatability and precision in motion. The exoskeleton integrates a brain–computer interface (BCI) that utilizes electroencephalographic signals for therapy selection and engagement enabling user-driven interaction. The EEG data extraction was possible by using the UltraCortex Mark IV headset, with electrodes positioned according to the international 10–20 system, targeting alpha-band activity in channels O1, O2, P3, P4, Fp1, and Fp2. These channels correspond to occipital (O1, O2), parietal (P3, P4), and frontal pole (Fp1, Fp2) regions, associated with visual processing, sensorimotor integration, and attention-related activity, respectively. This approach enables a more adaptive and personalized rehabilitation experience by allowing the user to influence therapy mode selection through real-time feedback. Experimental evaluation across five subjects showed an overall mean accuracy of 86.25% in alpha wave detection for EEG-based therapy selection. The PD control strategy achieved smooth trajectory tracking with a mean angular error of approximately 1.70°, confirming both the reliability of intention detection and the mechanical precision of the exoskeleton. Also, our core contributions in this research are compared with similar studies inspired by the rehabilitation needs of stroke patients. In this research, the proposed system demonstrates the potential of integrating robotic systems, control theory, and EEG data processing to improve rehabilitation outcomes for individuals with upper-limb motor deficits, particularly post-stroke patients. By focusing the exoskeleton on a single degree of freedom and employing low-cost manufacturing through 3D printing, the system remains affordable across a wide range of economic contexts. This design choice enables deployment in diverse clinical settings, both public and private. Full article

Field residue trials were conducted in greenhouse-grown cabbage at both recommended and double dosages to evaluate the degradation dynamics and dietary risks of three pesticides (azoxystrobin, thiamethoxam, and carbendazim). In this study, a quick, easy, cheap, effective, rugged, and safe (QuEChERS) method combined with liquid chromatography tandem mass spectrometry was developed to measure the residues of three pesticides in cabbage. The mean recoveries of three pesticides in cabbage were 82.5–104.2%, with relative standard deviations of 2.1–5.2%, meeting the requirements of residual analysis. Based on first-order kinetics, the half-lives of the three pesticides in cabbage were 11.55–33.00 d under field conditions. The health risks associated with three pesticides in cabbage were evaluated using the risk quotient (RQ) method and the EFSA PRIMo 3.1 model. In the final residue experiment, the dietary exposure risks of azoxystrobin and thiamethoxam were all acceptable for children and adults regardless of the dosage or pre-harvest intervals, with the risk quotient (RQ) ranging from 0.040 to 0.363 and 0.022 to 0.417, respectively. However, carbendazim intake posed unacceptable health risks for consumers, with RQ significantly exceeding 1. The EFSA PRIMo 3.1 model also indicated high %ADI values for carbendazim, consistent with the RQ results. Given the significant residual risk associated with carbendazim in cabbage, limiting its use on this crop is recommended. Full article
