An analysis of the stability and bifurcation of a discrete-time predator-prey model with the slow-fast effect on the predator.

In many environments, predators have significantly longer lives and meet several generations of prey, or the prey population reproduces rapidly. The slow-fast effect can best describe such predator-prey interactions. The slow-fast effect ε can be considered as the ratio between the predator's linear death rate and the prey's linear growth rate. This paper examines a slow-fast, discrete predator-prey interaction with prey refuge and herd behavior to reveal its complex dynamics. Our methodology employs the eigenvalues of the Jacobian matrix to examine the existence and local stability of fixed points in the model. Through the utilization of bifurcation theory and center manifold theory, it is demonstrated that the system undergoes period-doubling bifurcation and Neimark-Sacker bifurcation at the positive fixed point. The hybrid control method is utilized as a means of controlling the chaotic behavior that arises from these bifurcations. Moreover, numerical simulations are performed to demonstrate that they are consistent with analytical conclusions and to display the complexity of the model. At the interior fixed point, it is shown that the model undergoes a Neimark-Sacker bifurcation for larger values of the slow-fast effect parameter by using the slow-fast effect parameter ε as the bifurcation parameter. This is reasonable since a large ε implies an approximate equality in the predator's death rate and the prey's growth rate, automatically leading to the instability of the positive fixed point due to the slow-fast impact on the predator and the presence of prey refuge.

Exploring how to improve the involvement of Polish and South Asian communities around big data research. A qualitative study using COM-B model.

Introduction: Involving public contributors helps researchers to ensure that public views are taken into consideration when designing and planning research, so that it is person-centred and relevant to the public. This paper will consider public involvement in big data research. Inclusion of different communities is needed to ensure everyone's voice is heard. However, there remains limited evidence on how to improve the involvement of seldom-heard communities in big data research. Objectives: This study aims to understand how South Asians and Polish communities in the UK can be encouraged to participate in public involvement initiatives in big data research. Methods: Forty interviews were conducted with Polish (n=20) and South Asian (n=20) participants on Zoom. The participants were living in the United Kingdom and had not previously been involved as public contributors. Transcribed interviews were analysed using reflexive thematic analysis. Results: We identified eight themes. The 'happy to reuse data' theme sets the scene by exploring our participants' views towards big data research and under what circumstances they thought that data could be used. The remaining themes were mapped under the capability-opportunity-motivation-behaviour (COM-B) model, as developed by Michie and colleagues. This allowed us to discuss multiple factors that could influence people's willingness to become public contributors. Conclusions: Our study is the first to explore how to improve the involvement and engagement of seldom-heard communities in big data research using the COM-B model. The results have the potential to support researchers who want to identify what can influence members of the public to be involved. By using the COM-B model, it is possible to determine what measures could be implemented to better engage these communities.

Tapping into the power of coproduction and knowledge mobilisation: Exploration of a facilitated interactive group learning approach to support equity-sensitive decision-making in local health and care services.

BACKGROUND: We report on a study of a facilitated interactive group learning approach, through Collaborative Implementation Groups (CIGs), established to enhance capacity for equity-sensitive evaluation of healthcare services to inform local decision-making: (1) What was the experience of participants of the CIGs? (2) How was knowledge mobilisation achieved? (3) What are the key elements that enhance the process of coproducing equity-sensitive evaluations? METHODS: A thematic analysis of qualitative data obtained from focus group (FG) discussions and semistructured interviews exploring the experiences of participants. All FGs included representation of participants from different projects across the programme. Interviews were conducted with a member from each of the teams participating in the first cohort after their final workshop. RESULTS: We identified four themes to illustrate how the approach to delivering intensive and facilitated training supported equity-sensitive evaluations of local healthcare services: (1) Creating the setting for coproduction and knowledge mobilisation; (2) establishing a common purpose, meaning and language for reducing health inequalities; (3) making connections and brokering relationships and (4) challenging and transforming the role of evaluation. CONCLUSION: We report on the implementation of a practical example of engaged scholarship, where teams of healthcare staff were supported with resources, interactive training and methodological advice to evaluate their own services, enabling organisations to assemble timely practical and relevant evidence that could feed directly into local decision-making. By encouraging mixed teams of practitioners, commissioners, patients, the public and researchers to work together to coproduce their evaluations, the programme also aimed to systematise health equity into service change. The findings of our study illustrate that the approach to delivering training gave participants the tools and confidence to address their organisation's stated aims of reducing health inequalities, coproduce evaluations of their local services and mobilise knowledge from a range of stakeholders. PATIENT OR PUBLIC CONTRIBUTION: The research question was developed collaboratively with researchers, partner organisations and public advisers (PAs). PAs were involved in meetings to agree on the focus of this research and to plan the analysis. N. T. is a PA and coauthor, contributing to the interpretation of findings and drafting of the paper.

'To me, it's ones and zeros, but in reality that one is death': A qualitative study exploring researchers' experience of involving and engaging seldom-heard communities in big data research.

BACKGROUND: Big data research requires public support. It has been argued that this can be achieved by public involvement and engagement to ensure that public views are at the centre of research projects. Researchers should aim to include diverse communities, including seldom-heard voices, to ensure that a range of voices are heard and that research is meaningful to them. OBJECTIVE: We explored how researchers involve and engage seldom-heard communities around big data research. METHODS: This is a qualitative study. Researchers who had experience of involving or engaging seldom-heard communities in big data research were recruited. They were based in England (n = 5), Scotland (n = 4), Belgium (n = 2) and Canada (n = 1). Twelve semistructured interviews were conducted on Zoom. All interviews were audio-recorded and transcribed, and we used reflexive thematic analysis to analyse participants' experiences. RESULTS: The analysis highlighted the complexity of involving and engaging seldom-heard communities around big data research. Four themes were developed to represent participants' experiences: (1) abstraction and complexity of big data, (2) one size does not fit all, (3) working in partnership and (4) empowering the public contribution. CONCLUSION: The study offers researchers a better understanding of how to involve and engage seldom-heard communities in a meaningful way around big data research. There is no one right approach, with involvement and engagement activities required to be project-specific and dependent on the public contributors, researchers' needs, resources and time available. PATIENT AND PUBLIC INVOLVEMENT: Two public contributors are authors of the paper and they were involved in the study design, analysis and writing.

Public contributors' preferences for the organization of remote public involvement meetings in health and social care: A discrete choice experiment study.

INTRODUCTION: Covid-19 expanded the use of remote working to engage with public contributors in health and social care research. These changes have the potential to limit the ability to participate in patient and public involvement and engagement (PPIE) for some public contributors. It is therefore important to understand public contributors' preferences, so that remote working can be organized in an optimal way to encourage rather than discourage participation. METHODS: We use an economic preference elicitation tool, a discrete choice experiment (DCE), via an online survey, to estimate public contributors' preferences for and trade-offs between different features of remote meetings. The features were informed by previous research to include aspects of remote meetings that were relevant to public contributors and amenable to change by PPIE organizers. RESULTS: We found that public contributors are more likely to participate in a PPIE project involving remote meetings if they are given feedback about participation; allowed to switch their camera off during meetings and step away if/when needed; were under 2.5 h long; organized during working hours, and are chaired by a moderator who can ensure that everyone contributes. Different combinations of these features can cause estimated project participation to range from 23% to 94%. When planning PPIE and engaging public contributors, we suggest that resources are focused on training moderators and ensuring public contributors receive meeting feedback. DISCUSSION AND CONCLUSION: Project resources should be allocated to maximize project participation. We provide recommendations for those who work in public involvement and organize meetings on how resources, such as time and financial support, should be allocated. These are based on the preferences of existing public contributors who have been involved in health and social care research. PATIENT OR PUBLIC CONTRIBUTION: We had a public contributor (Naheed Tahir) as a funded coapplicant on the UKRI ESRC application and involved members of the North West Coast Applied Research Collaboration (NWC ARC) Public Advisor Forum at every stage of the project. The survey design was informed from three focus groups held with NWC ARC public contributors. The survey was further edited and improved based on the results of six one-to-one meetings with public contributors.

Outcome measures for economic evaluations and cost-effectiveness analyses of interventions for people with intellectual disabilities: A methodological systematic review.

BACKGROUND: Mainstream economic evaluations methods may not be appropriate to capture the range of effects triggered by interventions for people with intellectual disabilities. In this systematic review, we aimed to identify, assess and synthesise the arguments in the literature on how the effects of interventions for people with intellectual disabilities could be measured in economic evaluations. METHOD: We searched for studies providing relevant arguments by running multi-database, backward, forward citation and grey literature searches. Following title/abstract and full-text screening, the arguments extracted from the included studies were summarised and qualitatively assessed in a narrative synthesis. RESULTS: Our final analysis included three studies, with their arguments summarised in different methodological areas. CONCLUSIONS: Based on the evidence, we suggest the use of techniques more attuned to the population with intellectual disabilities, such sensitive preference-based instruments to collect health states data, and mapping algorithms to obtain utility values.

Remote working in public involvement: findings from a mixed methods study.

BACKGROUND: This paper considers remote working in patient public involvement and engagement (PPIE) in health and social care research. With the advent of the Covid-19 pandemic and associated lock-down measures in the UK (from March 2020), PPIE activities switched to using remote methods (e.g., online meetings), to undertake involvement. Our study sought to understand the barriers to and facilitators for remote working in PPIE by exploring public contributors' and PPIE professionals' (people employed by organisations to facilitate and organise PPIE), experiences of working remotely, using online and digital technologies. A particular focus of our project was to consider how the 'digital divide' might negatively impact on diversity and inclusion in PPIE in health and social care research. METHODS: We used a mixed method approach: online surveys with public contributors involved in health and social care research, online surveys with public involvement professionals, and qualitative interviews with public contributors. We co-produced the study with public contributors from its inception, design, subsequent data analysis and writing outputs, to embed public involvement throughout the study. RESULTS: We had 244 respondents to the public contributor survey and 65 for the public involvement professionals (PIPs) survey and conducted 22 qualitative interviews. Our results suggest public contributors adapted well to working remotely and they were very positive about the experience. For many, their PPIE activities increased in amount and variety, and they had learnt new skills. There were both benefits and drawbacks to working remotely. Due to ongoing Covid restrictions during the research project, we were unable to include people who did not have access to digital tools and our findings have to be interpreted in this light. CONCLUSION: Participants generally favoured a mixture of face-to-face and remote working. We suggest the following good practice recommendations for remote working in PPIE: the importance of a good moderator and/or chair to ensure everyone can participate fully; account for individual needs of public contributors when planning meetings; provide a small expenses payment alongside public contributor fees to cover phone/electricity or WiFi charges; and continue the individual support that was often offered to public contributors during the pandemic.

This paper looks at remote working in patient public involvement and engagement (PPIE) in health and social care research. When the Covid-19 pandemic began and the UK went into lock-down in March 2020, PPIE activities began to use remote working methods, such as Zoom or Teams online meetings. We co-developed a study to understand the experiences of both public contributors and PPIE professionals, those who are employed to organise PPIE, of working remotely. We were particularly interested in how remote working might affect diversity and inclusion in PPIE in health and social care research. We ran online surveys for public contributors and public involvement professionals and conducted semi-structured interviews with public contributors. We co-produced the study with public contributors to embed public involvement throughout the study. We had 244 respondents to the public contributor survey, 65 for the public involvement professionals survey and conducted 22 qualitative interviews. Due to ongoing Covid restrictions during the research project we could not include people who did not have access to digital tools, and this is a limitation of our project. We found that public contributors generally liked working remotely and, for many, their PPIE activities increased. There were both benefits and drawbacks to working remotely. From our findings, we have made a number of suggestions for how to run remote meetings in PPIE and what to prioritise based on the areas public contributors thought were important (such as one-to-one support).

Public involvement and engagement in big data research: protocol for a scoping review and a systematic review of delivery and effectiveness of strategies for involvement and engagement.

INTRODUCTION: Big data research has grown considerably over the last two decades. This presents new ethical challenges around consent, data storage and anonymisation. Big data research projects require public support to succeed and it has been argued that one way to achieve this is through public involvement and engagement. To better understand the role public involvement and engagement can play in big data research, we will review the current literature. This protocol describes the planned review methods. METHODS AND ANALYSIS: Our review will be conducted in two stages. In the first stage, we will conduct a scoping review using Arksey and O'Malley methodology to comprehensively map current evidence on public involvement and engagement in big data research. Databases (CINAHL, Health Research Premium Collection, PubMed, Scopus, Web of Science) and grey literature will be searched for eligible papers. We provide a narrative description of the results based on a thematic analysis. In the second stage, out of papers found in the scoping review which discuss involvement and engagement strategies, we will conduct a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, exploring the delivery and effectiveness of these strategies. We will conduct a qualitative synthesis. Relevant results from the quantitative studies will be extracted and placed under qualitative themes. Individual studies will be appraised through Mixed Methods Appraisal Tool (MMAT), we will then assess the overall confidence in each finding through Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual). Results will be reported in a thematic and narrative way. ETHICS AND DISSEMINATION: This protocol sets out how the review will be conducted to ensure rigour and transparency. Public advisors were involved in its development. Ethics approval is not required. Review findings will be presented at conferences and published in peer-reviewed journals.

The impact of COVID-19 social distancing and isolation recommendations for Muslim communities in North West England.

INTRODUCTION: People from Minority Ethnic backgrounds living in the UK are at greater risk of not only contracting COVID-19, but also experiencing serious consequences of the virus. These emerging health inequalities mirror those already evident in UK society. AIM: The aim of this study was to understand how COVID-19 and the associated imposed restrictions affected the lives of people from the Muslim community living in the North West of England. METHOD: Twenty-five in-depth qualitative interviews and four focus groups (n = 22) explored individual experiences of COVID-19 and imposed restrictions. Data were analysed thematically. FINDINGS: The virus and associated imposed restrictions had negative impacts on the psychological wellbeing of participants, their families and the wider community. Worry and low mood were particular features of participant's pandemic stories. Main concerns were those of contracting and transmitting the virus to others and employment-related difficulties. Low mood was particularly linked to the impact of restrictions on fundamental interactions embedded within cultural and religious practices. These practices are central to feelings of belonging and connectedness within the Muslim community. Religious beliefs were important in helping to mitigate psychological distress for some participants. CONCLUSION: Psychological distress was associated with COVID-19 virus and impact of COVID-19 restrictions on livelihoods and fundamental human interactions. Better provision of culturally appropriate information, improving local channels of communication and practical support are important during times of pandemic when usual support systems may be disrupted.

How do Muslim community members perceive Covid-19 risk reduction recommendations - a UK qualitative study?

INTRODUCTION: The evidence is now unequivocal that people from Black and Minority Ethnic Backgrounds (BAME) living in the UK are disproportionately affected by covid-19. There is growing evidence that the reasons for this difference are multi-factorial and need further exploration. AIM: The aim of this study was to understand better, perceptions of risk and responses to covid-19 of members of the Muslim community living in the North West of England, and to understand the facilitators and barriers to adherence to restrictions and guidance measures. METHOD: A total of 47 participants took part in 25 in-depth qualitative interviews and four focus groups (n=22) that explored perceptions of risk and responses to risk from covid-19. Data were analysed thematically. FINDINGS: Participants were aware of the mechanism of transmission of covid-19 and took steps to mitigate risk of transmission including, observing a range of hygiene practices and following social distancing guidance. Increased risk of covid-19 for BAME populations was explained largely in terms of exposure to the virus due to the types of employment people from BAME populations are employed in. Limitations both within the working environment and more generally in public spaces, was identified as problematic for effective social distancing. The closure of mosques sent out a strong message about the seriousness of the virus and religious teachings reinforced hygiene and social distancing guidelines. CONCLUSION: Across society there are people that adhere to restrictions and guidelines and those that do not. Improving local information provision and communication pathways during times of the pandemic, could aid understanding of risk and promote adherence to social distancing restrictions.

A systematic review of barriers and enablers to South Asian women's attendance for asymptomatic screening of breast and cervical cancers in emigrant countries.

OBJECTIVES: The aim of this review was to identify the cultural, social, structural and behavioural factors that influence asymptomatic breast and cervical cancer screening attendance in South Asian populations, in order to improve uptake and propose priorities for further research. DESIGN: A systematic review of the literature for inductive, comparative, prospective and intervention studies. We searched the following databases: MEDLINE/In-Process, Web of Science, EMBASE, SCOPUS, CENTRAL, CDSR, CINAHL, PsycINFO and PsycARTICLES from database inception to 23 January 2018. The review included studies on the cultural, social, structural and behavioural factors that influence asymptomatic breast and cervical cancer screening attendance and cervical smear testing (Papanicolaou test) in South Asian populations and those published in the English language. The framework analysis method was used and themes were drawn out following the thematic analysis method. SETTINGS: Asymptomatic breast or cervical screening. PARTICIPANTS: South Asian women, including Bangladeshi, Indian, Pakistani, Sri Lankan, Bhutanese, Maldivian and Nepali populations. RESULTS: 51 included studies were published between 1991 and 2018. Sample sizes ranged from 25 to 38 733 and participants had a mean age of 18 to 83 years. Our review showed that South Asian women generally had lower screening rates than host country women. South Asian women had poorer knowledge of cancer and cancer prevention and experienced more barriers to screening. Cultural practices and assumptions influenced understandings of cancer and prevention, emphasising the importance of host country cultures and healthcare systems. CONCLUSIONS: High-quality research on screening attendance is required using prospective designs, where objectively validated attendance is predicted from cultural understandings, beliefs, norms and practices, thus informing policy on targeting relevant public health messages to the South Asian communities about screening for cancer.
