    Navigating the gAI Landscape: Insights from a Physics Education Survey

    Get PDF
    A survey of physics students at Durham University sheds some light on the students' current use and understanding of gAI and their concerns for the future and the education sector. Physics students highlight that the main use of gAI is for computational assistance, followed by its use as a valuable tool for simplifying complex physics concepts and providing alternative explanations. Overall, students do not trust gAI and cross-check its output. They agree with the department’s policy concerning gAI and express mixed views regarding its use for providing feedback and assessing students’ work. Differences across levels have been found, with the students’ confidence in effectively using gAI increasing with level, together with resistance to the possibility of using gAI to assess their work. Though online assessments remain popular, their popularity decreases with the level

    Identifying prognostic structural features in tissue sections of colon cancer patients using point pattern analysis

    Diagnosis and prognosis of cancer is informed by the architecture inherent in cancer patient tissue sections. This architecture is typically identified by pathologists, yet advances in computational image analysis facilitate quantitative assessment of this structure. In this article we develop a spatial point process approach in order to describe patterns in cell distribution within tissue samples taken from colorectal cancer (CRC) patients. In particular, our approach is centered on the Palm intensity function. This leads to taking an approximate-likelihood technique in fitting point processes models. We consider two Neyman-Scott point processes and a void process, fitting these point process models to the CRC patient data. We find that the parameter estimates of these models may be used to quantify the spatial arrangement of cells. Importantly, we observe characteristic differences in the spatial arrangement of cells between patients who died from CRC and those alive at follow-up

    Achieving patient weighing in UK primary care. A conversation analytic study

    Addressing issues of weight with people with type 2 diabetes is increasingly becoming part of the workload of primary care. This includes taking weight measurements during consultations. Evidence suggests that weighing is experienced as difficult for health professionals and patients. This study explores how weighing is accomplished and identifies strategies and practices that can be used in primary care settings. Data are drawn from two large UK based archives of over 600 audio and video recorded primary care consultations. Conversation analysis was used to systematically inspect the consultation data. We identified the linguistic practices employed by GPs and resulting interactions around the measurement of weight in primary care. Seven consultations form this corpus. We identify the sequential interactional pattern through which GPs and patients engage to achieve weighing and identify delicacy features in GPs talk which are used to build alignment with patients to achieve weighing. The analysis also highlighted the ways in which GPs justify their need to weigh patients, including marking the measurement as clinically necessary and preferring a need for an objective measure of weight. The analyses highlight that patient responses to requests to weigh are varied and that weighing patients can necessitate considerable interactional effort. Achieving weighing of patients in primary care consultations requires considerable interactional work between GPs and patients and it is important for the delicacy of these requests to be appreciated. There is a need for greater attention to how to achieve weighing, given the increasing attention weight has in relation to health

    Attitudes to the use of animals in biomedical research: Effects of stigma and selected research project summaries

    Get PDF
    Three groups of participants (largely recruited from the UK) completed a survey to examine attitudes to the use of animals in biomedical research, after reading the lay (N = 182) or technical (N = 201) summary of a research project, or no summary (N = 215). They then completed a survey comprising the animal attitude (AAS), animal purpose (APQ), belief in animal mind (BAM) and empathy quotient (EQ) scales. The APQ was adapted to assess attitudes towards the use of animals for research into disorders selected to be perceived as controllable and so ‘blameworthy’ and potentially stigmatised (addiction and obesity) and ‘psychological’ (schizophrenia and addiction) versus ‘physical’ (cardiovascular disease and obesity), across selected species (rats, mice, fish pigs and monkeys). Thus, the APQ was used to examine how the effects of perceived controllability and the nature of the disorder affected attitudes to animal use, in different species and in the three summary groups. As expected, attitudes to animal use as measured by the AAS and the APQ (total) correlated positively with BAM and EQ scores, consistent with the assumption that the scales all measured pro-welfare attitudes. Participants in the two research summary groups did not differentiate the use of rats, mice and fish (or fish and pigs in the technical summary group), whereas all species were differentiated in the no summary group. Participants given the lay summary were as concerned about the use of animals for schizophrenia as for addiction research. APQ ratings otherwise indicated more concern for animals used for addiction research (and for obesity compared to cardiovascular disease in all summary groups). Therefore, the information provided by a research project summary influenced attitudes to use of animals in biomedical research. However, there was no overall increase in agreement with animal use in either of the summary groups

    Developing an implementation strategy for a digital health intervention: an example in routine healthcare.

    BACKGROUND: Evidence on how to implement new interventions into complex healthcare environments is often poorly reported and indexed, reducing its potential to inform initiatives to improve healthcare services. Using the implementation of a digital intervention within routine National Health Service (NHS) practice, we provide an example of how to develop a theoretically based implementation plan and how to report it transparently. In doing so we also highlight some of the challenges to implementation in routine healthcare. METHODS: The implemented intervention was HeLP-Diabetes, a digital self-management programme for people with Type 2 Diabetes, which was effective in improving diabetes control. The target setting for the implementation was an inner city London Clinical Commissioning Group in the NHS comprised of 34 general practices. HeLP-Diabetes was designed to be offered to patients as part of routine diabetes care across England. Evidence synthesis, engagement of local stakeholders, a theory of implementation (Normalization Process Theory), feedback, qualitative interviews and usage data were used to develop an implementation plan. RESULTS: A new implementation plan was developed to implement HeLP-Diabetes within routine practice. Individual component strategies were selected and developed informed by Normalization Process Theory. These strategies included: engagement of local opinion leaders, provision of educational materials, educational visits, educational meetings, audit and feedback and reminders. Additional strategies were introduced iteratively to address barriers that arose during the implementation. Barriers largely related to difficulties in allocating resources to implement the intervention within routine care. CONCLUSION: This paper provides a worked example of implementing a digital health intervention. The learning from this work can inform others undertaking the work of planning and executing implementation activities in routine healthcare. Of particular importance is: the selection of appropriate theory to guide the implementation process and selection of strategies; ensuring that enough attention is paid to planning implementation; and a flexible approach that allows response to emerging barriers

    Health care professionals' views towards self-management and self-management education for people with type 2 diabetes

    Get PDF
    OBJECTIVES: Significant problems with patients engaging with diabetes self-management education (DSME) exist. The role of healthcare professionals (HCPs) has been highlighted, with a lack of enthusiasm, inadequate information provision and poor promotion of available programmes all cited as affecting patients' decisions to attend. However, little is known about HCPs' views towards DSME. This study investigates the views of HCPs towards self-management generally and self-management in the context of DSME more specifically. DESIGN: A qualitative study using semi-structured interviews to investigate HCPs views of type 2 diabetes self-management and DSME. Data were analysed thematically and emergent themes were mapped on to the constructs of Normalisation Process Theory (NPT). SETTING: Two boroughs in London, UK. PARTICIPANTS: Sampling was purposive to recruit a diverse range of professional roles including GPs, practice nurses, diabetes specialist nurses, healthcare assistants (HCAs), receptionists and commissioners of care. RESULTS: Interviews were conducted with 22 participants. The NPT analysis demonstrated that while a self-management approach to diabetes care was viewed by HCPs as necessary and, in principle, valuable, the reality is much more complex. HCPs expressed ambivalence about pushing certain patients into self-managing, preferring to retain responsibility. There was a lack of awareness among HCPs about the content of DSME and benefits to patients. Commitment to and engagement with DSME was tempered by concerns about suitability for some patients. There was little evidence of communication between providers of group-based DSME and HCPs or of HCPs engaging in work to follow-up non-attenders. CONCLUSIONS: HCPs have concerns about the appropriateness of DSME for all patients and discussed challenges to engaging with and performing the tasks required to embed the approach within practice. DSME, as a means of supporting self-management, was considered important in theory, but there was little evidence of HCPs seeing their role as extending beyond providing referrals
