Beyond Borders: Understanding the Motivations and Experiences of International Students at Ulster University
Get PDFThis multi-phase research study explored the motivations, expectations, and experiences of international students at Ulster University. Drawing on data from over 140 students with overseas fee status, the study highlighted key factors influencing university choice—namely, academic reputation and affordability—alongside the complex realities of adapting to a new educational and cultural environment. Students reported challenges with communication, assessment styles, and integration, emphasising the need for tailored, ongoing support beyond induction. The findings recommended inclusive teaching practices, cross-cultural staff training, scaffolded assessments, and greater internationalisation of curricula. Initiatives such as peer mentoring, group work, and culturally responsive services were seen as essential for fostering belonging and success. The study underscores the importance of listening to student voices and designing systems that recognise diverse educational experiences. By acting on these insights, institutions can build inclusive, globally engaged campuses where international students—and the wider community—can thrive
Procuring Promising Provisions: the British Patent System and the Navy Proviso, 1794-1831
Get PDFIn 1794, the British State intervened in the patent system by introducing the Navy proviso, a legal proviso targeted at select patents compelling the patentee to supply their invention to the State on terms set by state-appointed adjudicators. This study employs new patent and archival data to examine the proviso’s origins, administration, and which technologies it was targeted at. Our findings reveal the state targeted technologies to enhance logistical and operational capacities during wartime, addressing potential undersupply in private markets. Functioning similarly to patent buyouts and compulsory licensing, the proviso may have encouraged technical change and knowledge dissemination
Social policy in a political vacuum: Women's experiences of hunger during the Cost‐of‐Living Crisis in Northern Ireland
Get PDFBetween 2022 and 2024, there was no devolved government functioning in Northern Ireland. This protracted absence of government occurred in the aftermath of the Covid‐19 pandemic and during what is arguably the worst economic crisis of recent years. Women are more vulnerable to hardship during economic crisis and thus it is unsurprising that the Cost‐of‐Living Crisis is hitting women hardest. This paper examines increasing food insecurity for women in Northern Ireland and the implications for the realisation of their human right to an adequate standard of living. The UK Government has ratified the International Covenant on Economic, Social and Cultural Rights, which provides a legal duty to ensure that everyone has adequate access to food. However, increasing numbers of food banks and ill health related to insufficient food intake indicates that there is a fundamental problem. This article draws on 20 focus groups with 250 women on a low‐income to explore their experiences of the Cost‐of‐Living Crisis in Northern Ireland. The research found that women routinely skipped meals; described feelings of shame and guilt associated with struggling to feed their children; and discussed difficulties associated with purchasing food. Much of the pain associated with the hunger experienced by these women and children is hidden within the private sphere of the home. This article intends to shine a light on women's experiences and will reflect on the necessary policy change required to ensure compliance with international human rights obligations
Anti-inflammatory effects of phytocannabinoids and terpenes on inflamed Tregs and Th17 cells in vitro
Get PDFAims: Phytocannabinoids and terpenes from Cannabis sativa have demonstrated limited anti-inflammatory and analgesic effects in several inflammatory conditions. In the current study, we test the hypothesis that phytocannabinoids exert immunomodulatory effects in vitro by decreasing inflammatory cytokine expression and activation. Key methods: CD3/CD28 and lipopolysaccharide activated peripheral blood mononuclear cells (PBMCs) from healthy donors (n = 6) were treated with phytocannabinoid compounds and terpenes in vitro. Flow cytometry was used to determine regulatory T cell (Treg) and T helper 17 (Th17) cell responses to treatments. Cell pellets were harvested for qRT-PCR gene expression analysis of cytokines, cell activation markers, and inflammation-related receptors. Cell culture supernatants were analysed by ELISA to quantify IL-6, TNF-α and IL-10 secretion. Main findings: In an initial screen of 20 μM cannabinoids and terpenes which were coded to blind investigators, cannabigerol (GL4a), caryophyllene oxide (GL5a) and gamma-terpinene (GL6a) significantly reduced cytotoxicity and gene expression levels of IL6, IL10, TNF, TRPV1, CNR1, HTR1A, FOXP3, RORC and NFKΒ1. Tetrahydrocannabinol (GL7a) suppression of T cell activation was associated with downregulation of RORC and NFKΒ1 gene expression and reduced IL-6 (p < 0.0001) and IL10 (p < 0.01) secretion. Cannabidiol (GL1b) significantly suppressed activation of Tregs (p < 0.05) and Th17 cells (p < 0.05) in a follow-on in vitro dose-response study. IL-6 (p < 0.01) and IL-10 (p < 0.01) secretion was significantly reduced with 50 μM cannabidiol. Significance: The study provides the first evidence that cannabidiol and tetrahydrocannabinol suppress extracellular expression of both anti- and pro-inflammatory cytokines in an in vitro PBMC model of inflammation.</p
Age structure and age heaping: solving Ireland’s post-Famine digit preference puzzle
Get PDFThe quality of age reporting in Ireland worsened in the years after the 1845–1852 Great Irish Famine, even as measures of educational attainment improved. We show how Ireland’s age structure partly accounts for this seemingly conflicting pattern. Specifically, we argue that a greater propensity to emigrate typified the youngest segment (23–32-year-olds) used in conventional indices of age heaping. Any quantification of age heaping patterns must therefore be interpreted considering an older underlying population which is inherently more likely to heap. We demonstrate how age heaping indices can adjust for such demographic change by introducing age standardization
Interventions in food business organisations to improve food safety culture: a rapid evidence assessment
Get PDFThe European Commission recently adopted Commission Regulation (EU) 2021/382 requiring food businesses to establish and provide evidence of a food safety culture (FSC). FSC incorporates management systems, risk perceptions, leadership, communication, environment and commitment to ensure food safety. This review (n = 20) investigates food safety interventions in food businesses to identify effective strategies to improve food safety practices and FSC, and to provide recommendations for improving FSC. Results found that most interventions focused on knowledge training and that workplace practical demonstrations produced the best outcomes. Similar training topics were used evidencing the existence of common training needs. Frequent training over longer time periods was most successful for behavioral change, yet no sustained behavioral change was reported, indicating that single knowledge-based interventions are insufficient, reinforcing repeated experiential learning to be incorporated into training. We suggest that FSC training should focus on FSC more broadly, rather than solely on knowledge training, and that management leadership skills in particular are important to ensure sustained positive change. This study contributes to knowledge by providing a summative overview of food safety interventions and how components of these may be used to enhance FSC in food businesses.</p
HARMamba: Efficient and Lightweight Wearable Sensor Human Activity Recognition Based on Bidirectional Mamba
Get PDFWearable sensor-based human activity recognition (HAR) is a critical research domain in activity perception. However, achieving high efficiency and long sequence recognition remains a challenge. Despite the extensive investigation of temporal deep learning models, such as convolutional neural networks, RNNs, and transformers, their extensive parameters often pose significant computational and memory constraints, rendering them less suitable for resource-constrained mobile health applications. This study introduces HARMamba, an innovative lightweight and versatile HAR architecture that combines selective bidirectional state-space model and hardware-aware design. To optimize real-time resource consumption in practical scenarios, HARMamba employs linear recursive mechanisms and parameter discretization, allowing it to selectively focus on relevant input sequences while efficiently fusing scan and recompute operations. The model employs independent channels to process sensor data streams, dividing each channel into patches and appending classification tokens to the end of the sequence. It utilizes position embedding to represent the sequence order. The patch sequence is subsequently processed by HARMamba Block, and the classification head finally outputs the activity category. The HARMamba Block serves as the fundamental component of the HARMamba architecture, enabling the effective capture of more discriminative activity sequence features. HARMamba outperforms contemporary state-of-the-art frameworks, delivering comparable or better accuracy with significantly reducing computational and memory demands. Its effectiveness has been extensively validated on four publicly available data sets, namely, PAMAP2, WISDM, UNIMIB SHAR, and UCI. The F1 scores of HARMamba on the four data sets are 99.74%, 99.20%, 88.23%, and 97.01%, respectively.</p
The impact of AI feedback on the accuracy of diagnosis, decision switching and trust in Radiography.
Get PDFArtificial intelligence decision support systems have been proposed to assist a struggling National Health Service (NHS) workforce in the United Kingdom. Its implementation in UK healthcare systems has been identified as a priority for deployment. Few studies have investigated the impact of the feedback from such systems on the end user. This study investigated the impact of two forms of AI feedback (saliency/heatmaps and AI diagnosis with percentage confidence) on student and qualified diagnostic radiographers’ accuracy when determining binary diagnosis on skeletal radiographs. The AI feedback proved beneficial to accuracy in all cases except when the AI was incorrect and for pathological cases in the student group. The self-reported trust of all participants decreased from the beginning to the end of the study. The findings of this study should guide developers in the provision of the most advantageous forms of AI feedback and direct educators in tailoring education to highlight weaknesses in human interaction with AI-based clinical decision support systems
Teaching note: assessing social work students on placement: a model for professional competence
Get PDFThis teaching note describes how the author (a practice teacher and university lecturer) retrospectively considered and applied the work of Jean Lave and Etienne Wenger; with a specific focus on situated learning, communities of practice and pre-qualifying social work education in Northern Ireland. Through this retrospective lens, this conceptual paper presents a new, inclusive model for practice teachers (practice educators) and social work students to use in professional supervision. The Social Work Placement Professional Competence (PPC) Model is presented as a supervisory tool to guide and frame professional discussions and critical analysis of student’s practice. The model can be used to critically reflect on the development of the students’ incremental learning, knowledge base, evidence of decision-making, assessment of need and ability to effectively manage risk.</p
Towards a Framework for Mapping Authentic Assessment to Competency in University Computing Education in the UK
Get PDFAcross various countries and jurisdictions, we have seen reports of a “graduate skills gap”, with higher-than-desired graduate unemployment and underemployment, as well as reports from employers that there is a mismatch between the competencies desired by employers and those evidenced by graduates. Graduate employment prospects are related to many complex intersecting factors, including human capital, individual attributes, individual career-building behaviours, labour market factors, and social capital. Alongside the graduate skills gap, there are also reports internationally of a ”digital skills gap”, with increasing demand for digital skills and a proclaimed shortage of diverse digital skills evidenced by the workforce. These circumstances appear to promote positive employment outcomes for computing graduates. However, there are reports in many jurisdictions, including the UK, of skills-gap-related issues for computing graduates. In response to these concerns, curricula guidance in the computing and engineering disciplines are increasingly promoting competency-based education (CBE) to develop graduates’ work readiness better and, hence, reduce the skills gap. Authentic Assessment, i.e. Assessment that addresses important problems or questions that require students to effectively and creatively apply their knowledge and disciplinary and personal skills, mirroring the challenges faced by adults or professionals in the real-world context, has also been advocated to reduce skills gaps between education and professional life. However, the link between CBE and Authentic Assessment in the computing discipline could benefit from further exploration.This paper explores the relationship between CBE and authentic assessment. Based on the guiding research question: “How can authentic assessment be employed to promote competency in computing degree programmes?”, the paper begins by providing theoretical underpinnings in the form of working definitions for competency and authentic assessment and the link between the two. This paper follows a proof-of-concept research approach conducted by evolutionary prototyping to develop a framework for exploring the relationship between authentic assessment and competency. The paper documents the validation of the framework by applying it to examples of practices from UK universities involved in the study. These illustrative examples show the framework in action. The paper concludes with a discussion of how the framework promotes learner competency development by authentic assessment. This approach has implications for enhancing how computing graduates address digital skills gaps and has the potential to be customised and adopted more broadly across STEM disciplines
