    • Constructing Self-Dual Codes from Group Rings and Reverse Circulant Matrices

      Gildea, Joe; Kaya, Abidin; Korban, Adrian; Yildiz, Bahattin; University of Chester; Sampoerna Academy; Northern Arizona University
      In this work, we describe a construction for self-dual codes in which we employ group rings and reverse circulant matrices. By applying the construction directly over different alphabets, and by employing the well known extension and neighbor methods we were able to obtain extremal binary self-dual codes of different lengths of which some have parameters that were not known in the literature before. In particular, we constructed three new codes of length 64, twenty-two new codes of length 68, twelve new codes of length 80 and four new codes of length 92.
    • Combining bioacoustics and occupancy modelling for improved monitoring of rare breeding bird populations

      Abrahams, Carlos; Geary, Matthew; Baker Consultants Ltd; Nottingham Trent University; University of Chester
      Effective monitoring of rare and declining species is critical to enable their conservation, but can often be difficult due to detectability or survey constraints. However, developments in acoustic recorders are enabling an important new approach for improved monitoring that is especially applicable for long-term studies, and for use in difficult environments or with cryptic species. Bioacoustic data may be effectively analysed within an occupancy modelling framework, as presence/absence can be determined, and repeated survey events can be accommodated. Hence, both occupancy and detectability estimates can be produced from large, coherent datasets. However, the most effective methods for the practical detection and identification of call data are still far from established. We assessed a novel combination of automated clustering and manual verification to detect and identify heathland bird vocalizations, covering a period of six days at 44 sampling locations Occupancy (Ψ) and detectability (p ) were modelled for each species, and the best fit models provided values of: nightjar Ψ=0.684, p=0.740, Dartford warbler Ψ=0.449 p=0.196 and woodlark Ψ=0.13 p=0.996. Including environmental covariates within the occupancy models indicated that tree, wetland and heather cover were important variables, particularly influencing detectability. The protocol used here allowed robust and consistent survey data to be gathered, with limited fieldwork resourcing, allowing population estimates to be generated for the target bird species. The combination of bioacoustics and occupancy modelling can provide a valuable new monitoring approach, allowing population trends to be identified, and the effects of environmental change and site management to be assessed.
    • Deteriorative Influences Upon the Morale of the British 21st Army Group in the Shadow of Operation ‘Market Garden’.

      Grady, Tim; Kirby-Jones, Harry, D, B. (University of ChesterUniversity of Chester, 2019-09-19)
      Operation ‘Market Garden’ was initiated by Allied forces on the 17th September 1944, ending on the 25th of the same month. Up until that point of the Second World War, it was the largest airborne landing to have ever been undertaken. The main aim of Operation ‘Market Garden’ was to open up an invasion route for the Allied forces into the north of Germany from the Netherlands. In order to do this, the operation sought to capture and cross a number of bridges over a series of rivers and canals, including the Rhine and the Maas. The first part of this operation - ‘Market’ - involved the landing of paratroopers in proximity to these bridges in order to capture and secure, awaiting part two of the operation. ‘Garden’ involved the movement of heavier units from Belgium, up through the Netherlands, relieving the units holding these bridges (See Source 0.01, 0.02, 0.03).
    • The operation of Article 4 of Rome II Regulation in English and Irish courts

    • Mangrove and mudflat food webs are segregated across four trophic levels, yet connected by highly mobile top predators

      Marley, Guy; Lawrence, Andrew; Phillip, Dawn; Hayden, Brian; Canadian Rivers Institute
      Seascape connectivity is crucial for healthy, resilient ecosystems and fisheries. Yet, our understanding of connectivity in turbid mangrove-lined estuaries—some of the world’s most productive ecosystems—is limited to macrotidal systems, and rarely incorporates highly mobile top predators. We analysed δ13C and δ15N isotope values of 7 primary producers, 24 invertebrate taxa, 13 fishes, 4 birds and 1 reptile to reveal trophic interactions within and between a mangrove and adjacent mudflat in a microtidal system of the Gulf of Paria, Orinoco River estuary. Primary producers, invertebrates and fishes collected within the mangrove were significantly depleted in 13C and 15N compared to those collected on the mudflat. Stable isotope mixing models showed that mangrove-derived carbon was predominantly assimilated by invertebrates (78 ± 5% SE) and fishes (88 ± 11%) sampled in the mangrove. In contrast, invertebrates and fishes sampled in the mudflat derived <21% of their carbon from mangrove sources. Instead, microphytobenthos and phytoplankton underpinned the mudflat food web. Scarlet ibis Eudocimus ruber and yellow-crowned night heron Nyctanassa violacea were also highly associated with mangrove carbon sources. However, osprey Pandion haliaetus, snowy egret Egretta thula and spectacled caiman Caiman crocodilus obtained carbon from both mangrove and mudflat sources, effectively integrating the food webs. The present study demonstrates simultaneous aspects of food web segregation and connectivity, as well as the importance of surveying the entire food web across a range of tidal systems when investigating seascape connectivity.
    • The use of photogrammetry and film in fostering understanding of early medieval history

      Lang, Roger (University of ChesterUniversity of Chester, 2019-09)
      The recent arrival of a growing body of freely available photogrammetric 3D models of early medieval stone sculptures gives the opportunity for educators to use them as virtual primary sources, either directly as navigable objects or through the medium of film. The research investigates their potential role in schools following the current national curriculum in England. The curriculum requirements are reviewed and their implementation investigated through a study of school websites and Ofsted reports in an English shire county. A search is made for suitable stone sculptures with 3D models, new ones are made where necessary, and the academic literature on the sculptures is reviewed. Lesson plans and resources are created and trialed in three primary schools in a method closely resembling cyclic Lesson Study methodology. The conclusion is that the process has demonstrated the potential for the use of 3D models to serve as the focus of engaging and challenging lessons.
    • From Siege to Emerging Leisure Town: Chester’s Recovery from the Civil War, 1646-1745

      Gaunt, Peter; Beech, Rachel (University of ChesterUniversity of Chester, 2019-09)
      By the end of 1647, Chester had been reduced to a damaged and diseased shell, suffering from the twin effects of civil war siege and plague. Reports stated that most of the capable working population had fled leaving only the poor and dying.1 However, only thirty years later Chester began to see marked improvements, with fashionable architecture, growing marketing and port trade, and a wealthy population of urban gentry. How the city was able to recover from its low state towards a comfortable and prosperous new identity – the ‘leisure town’ – will be explored in this dissertation
    • Why is China absent from the human remains debate

      Wu, Hukeyao (University of ChesterUniversity of Chester, 2019-09)
      The display of human remains has been widely studied and discussed by archaeologists and museum curators all around the world. The discussion on this topic involves the ethics, policies, and display methods faced by museums concerning the repatriation, storage, care, management and interpretation of human remains. China, however, has been absent from this debate. It is not that Chinese museums do not display human remains. On the contrary, some Chinese museums do exhibit human remains and proper practices and respect have been shown in some museums. In order to find out the reasons of China’s absence from the human remains debate, this article will review the relevant literature of Britain and China and analyse the possible reasons from four aspects, respectively: repatriation claims, authority, changed Chinese culture and display tendency. Besides, one case study of a Western Han dynasty female corpse displayed in the Hunan Museum will be reviewed as access to the Chinese context.
    • A study of the deposition of, and taphonomic processes affecting, plant macrofossil records for an island in Palaeolake Flixton, North Yorkshire

      Taylor, Barry; Clarke, Pauline (University of ChesterUniversity of Chester, 2019-12)
      Plant macrofossil analysis is used in the study of developing environments and is especially applied to the study of the formation of a hydrosere, due to the excellent preservation conditions usually found in the peat associated with the lakes infilling. Modern studies of the flora present in an area and the correlation to the associated macrofossils give proxies for the study of a Palaeolake, such as Lake Flixton in the Vale of Pickering, North Yorkshire. While the proxy studies broadly concur in the approach to be taken, the deposition and taphonomy of specific plant species and the value of any results, there are elements not considered in them, one being that here are no extant studies of the dispersal of macro-remains and the associated taphonomic processes that are particular to islands within a lake. This dissertation aims to correct this by studying No Name Hill, a former island within Palaeolake Flixton. Cores for examination were collected from the island during excavations in 2018 and the resultant data compared with previous studies from other sites around the lake. While the hydroseral succession was demonstrated consistently across the lake environment, the cores from the island highlighted differential processes of deposition and taphonomy affecting the macrofossil record. It is probable that the shoreline cores give a more generic picture of the environment of the lake and surroundings, while cores taken from an island produce results which are more reflective of the localised flora.
    • ‘The Madman out of The Attic’ Gendered Madness in Jane Eyre, Wuthering Heights, Villette, and The Tenant of Wildfell Hall

      Bury, Hannah (University of ChesterUniversity of Chester, 2019-12)
      The nineteenth-century ‘madwoman’ is critically established, but not always contentiously questioned or repudiated, within Brontë scholarship. This dissertation will therefore explore the possibility that the quintessentially ‘mad’ female can be replaced by the heavily flawed, and often equally ‘mad’ man, who continuously controls and represses her. Through a diachronic analysis of Bertha Mason and Lucy Snowe in Charlotte Brontë’s Jane Eyre and Villette, Catherine Earnshaw in Emily Brontë’s Wuthering Heights and Helen Graham in Anne Brontë’s The Tenant of Wildfell Hall, this project will demonstrate how and why the middleclass, ‘sane’ and respectable man can be met with character divergences and vices of his own. This undermines his credibility as a ‘doctor’ or a dictator in his treatment of women, which in turn vindicates and questions the validity and the ultimate cause of female ‘madness’ in the first instance. Chapters One and Two will trace Bertha and Catherine’s respective downfalls to death through ‘madness’, and their connecting relationships with both Rochester and Edgar. Chapter Three will examine how Lucy does manage to survive her mistreatment; yet, she is left without purpose or a definitive identity of her own as a result. In contrast to the preceding chapters, Chapter Four will inverse and redeem the trends of the nineteenth-century woman, ones which so heavily affected Bertha, Catherine and Lucy, as Helen survives her unfavourable experience. While Bertha, Catherine and Lucy react and succumb to their patriarchal repression in different ways, only Anne Brontë offers a solution to the polemical issues which all three authors raise. As she emancipates her heroine Helen, in contrast to repressing her further, she negotiates how an alternative and a more optimistic fate potentially awaits women who are entrapped within the rigid patriarchal systems of nineteenth-century literature and culture.
    • A phenomenological exploration of nursing students’ experience of raising a care concern in clinical practice

      Cooper, Elizabeth (University of ChesterUniversity of Chester, 2020-01)
      UK pre-registration healthcare students are expected to raise a care concern about unsafe situations whilst in clinical practice. The UK’s NHS is in the midst of a change to an open, honest and transparent culture which responds to a professional’s concern about patient care, to improve safety and prevent harm. Central to this change is improving the experience of registered healthcare professionals whose decision to raise a care concern is influenced by the organisational culture; this can create a difficult moral choice. The experience of nursing students who decide to raise a care concern has received little attention, and this study sought to explore this under-researched area. A literature review was undertaken which identified that the experience of nursing students who had raised a care concern had not been previously examined. To guide this study, Clarke Moustakas’ (1994) transcendental phenomenological methodology was used to explore nursing students’ lived experience of raising a care concern. Ten nursing students with experience of raising a care concern in clinical practice voluntarily participated in the study. Open interviews conducted between December 2016 and October 2017 were audio recorded and transcribed, exposing individual narratives of raising a care concern in clinical practice. The transcripts were analysed to produce a composite description which summarises nursing students’ lived experience, reflecting four themes or essences: 1) patient centred concern; 2) deciding how to act; 3) having emotional strength; and 4) feedback and support. These typify what it is like for nursing students to raise a care concern whilst in clinical practice. The findings were critically examined and suggest that compassion may motivate nursing students to act when faced with an unsafe situation, seeking to stop patient harm and suffering. Recognising this moral motivation, students described the relevance of emotional strength when dealing with the emotionally complex experience of facing difficult situations, with feedback and support providing comfort plus moral and emotional satisfaction. This study also explores the implications for professional practice, specifically the impact upon future teaching and learning approaches to facilitate nursing students’ ability to detect and act upon unsafe situations; providing listening opportunities to support students in clinical practice; and valuing nursing students who raise a care concern as role models and local clinical leaders. Recommendations include a new national campaign to improve the likelihood of nursing students raising care concerns and updating UK professional guidance.
    • British Military Veterans and the Criminal Justice System in the United Kingdom: Situating the Self in Veteran Research

      Mottershead, Richard (University of ChesterUniversity of Chester, 2019-11)
      The 21st Century has seen the continuation of armed conflict, exposing military personnel to the rigours of warfare and the challenges of transition back to a civilian identity. There has been a renewed realisation that there exists a sub-group within the criminal justice system (CJS) of veterans and whilst the exact figures are debated, their presence is not. This thesis seeks to capture the perspectives and experiences of veterans who are identified as exoffenders and those having been employed in the CJS as practitioners. The super-structuralist concept of the CJS collectively represent services of a ‘total institution’ that have shared similarities and differences to life within the ‘total institution’ of the Armed Forces. The life stories of the participants indicated that whilst one veteran life story trajectory (veteran practitioner) appeared to be able to adapt during the transition to a civilian identity successfully, there was evidence that the other veteran life story trajectory (veteran exoffender) found themselves segregated and isolated from a familiar veteran identity with few resources to survive the experience unscathed. This exploratory qualitative study provides emancipatory evidence that the process of entering the CJS as offenders often fails to address the origins of their criminal behaviour or from the wider social context that creates a cyclical response. The veteran practitioners appear to hold a crucial insight into the issues and seek to progress the CJS’s need to expand its knowledge base on the identification, diversion and management of veteran offenders. The study was theoretically informed through the use of reflexivity to articulate the internal and external dialogue of what is known and how it is known in understanding the lived experiences of 17 participants. Life stories were collected from in-depth interviews across the United Kingdom. The life stories were analysed thematically, providing insight and understanding through the elicitation of narratives derived from the contours of meaning from the participants’ (veterans) experiences and enunciating the two separate life story trajectories into the CJS. The findings of this study indicate the participants need to belong and explores how their veteran identity instilled in them both a source of strength and a feeling of anguish, as their new lives could not offer the same security and sense of belonging. The negative consequences of being identified as an offender often resulted in the emergence of stigma and associated shame upon themselves and their families. The life stories demonstrated disparities between the attempted empowering philosophies of the veteran practitioners and the practices imposed generally by the CJS. There were numerous examples of how the veterans’ prior exposure to the institution of the Armed Forces had shaped their experiences and engagement with the institutions of the CJS. Both sub-groups of veterans constructed positive ownership of their veteran identity which at times served to counterbalance their negative experiences of transition from military to a civilian identity. These constructions of their experiences highlight the vulnerability of this sub-group within the CJS and the failure of the system and wider society to address the consequences of military service on some veterans. This research raises the issue of the ‘fallout’ from the recruitment of youth from communities where established socio-economic deprivation has created fertile recruitment grounds for the Armed Forces. The analysis identifies a pragmatic need to address the gaps within the research literature as well as multi-agency working, in order to expand veteran peer support schemes. The voice of the veteran has been overlooked within the positivist research approach, this study seeks to capture the viewpoint of the veterans through reflexive exploratory research undertaken by a veteran researcher to understand the phenomena. Researching the experiences of veterans’ experiences of the CJS presented ethical and methodological challenges. The study has provided new knowledge and understanding that can be disseminated and used to improve current practices and policies.
    • Talent management and the HR function in cross-cultural mergers and acquisitions: The role and impact of bi-cultural identity

      Liu, Yipeng; email:; Vrontis, Demetris; email:; Visser, Max; email:; Stokes, Peter; email:; Smith, Simon; email:; Moore, Neil; email:; Thrassou, Alkis; email:; Ashta, Ashok
      Abstract This paper examines bi-cultural talent in relation to human resource management (HRM) practices in cross-cultural merger and acquisitions (M&A). The intersection of HRM, bi-cultural talent management and cross-cultural M&A literature proposes a conceptual framework to capture the complexity of bi-cultural talent management and reveals the dominant macro-characterization of the extant HRM literature focussing on a more micro-orientated perspective. The paper develops a matrix by underlining spatial dimensions (spanning micro-aspects of the individual employee through to the macro-entity of firm and its location in the macro-national cultural context) and temporal dimensions (consisting of pre-merger, during merger and post-merger phases). This provides a template which examines the multi-level dynamics of bi-cultural talent management. The argument identifies ways in which extant cross-cultural lenses require deeper understanding of bi-cultural talent management in M&A settings. Future research directions and agendas are identified.
    • A reflexive arts investigation: An examination of the shifting gendered identities of mother and daughter through psychodynamic and feminist discourses.

      Sampson-Chappell, Lynn (University of ChesterUniversity of Chester, 2019-02)
      This research is the culmination of nine years of collaborative and individual arts practice with my daughter, using a range of collaborative and individual art practices to document the stages of my daughter’s development and learning through play and experimentation with art materials. The thesis is a lived enquiry which gives my daughter authorship as co researcher, offering a unique insight into her understanding and learning through arts practice. The arts practice provides a voice to the child, which has been lost to the performativity metrics of the school institution. The research acknowledges the multiple identities of the researcher, mother, artist and educator. As an artist I live and embody the creative and critical inquiry, as the researcher I respond to the culture of the research community and as an educator / mother I respond to others involved in the artistic inquiry. The practice-based thesis consists of two interconnected elements: an exhibition of art practice created by me and my daughter working both symbiotically and independently accompanied by a written account of the process. The art work is a collection of early drawings and experimental mark-making, photographs, screen prints, casts and embossed papers which trace my daughter’s emotional development as she navigates her infancy, latency and emerging adolescence. At the same time the Exhibition documents the parallel processes in me as an artist/teacher and mother of my only child, through her infancy, childhood and adolescence. The practice-based thesis illustrates that healthy separation is a crucial feature of normal development, emerging identity and the journey from dependence, interdependence to independence. The shared and individual arts practice creates an external representation of what is usually an internal, invisible emotional struggle as mothers separate from their children and children strive for their right to become adults independent of their parents. This iii transitional movement is visible in the art practice. Psychodynamic ideas such as the mother as an object and a container are explored as boundaries are maintained by the mother despite being challenged by the daughter; at first these challenges are resisted and then, reluctantly relinquished by the mother. The mother’s own childhood is inevitably present in the art work and the analysis. This thesis adopts an autobiographical, ethnographic and reflexive approach, consequently the findings can only be subjective. It exposes a highly personal journey which is both painful and joyful. It offers insights into how an artist/teacher/mother can engage with a developing child through providing a containing relationship in which shared arts practice reveals and exposes in painstaking detail how separation is navigated as an ongoing, dynamic process. The art itself explores in very concrete ways how boundaries are sometimes held firmly and how they sometimes move, how emerging identity evolves, fades, changes and is finally brought into sharp relief. A parent who herself is not contained will find it difficult to contain her child through the ordinary turbulence of childhood.
    • Managers Managing Stress at Work: Exploring the experiences of managers managing employee stress in the social housing sector

      Wall, Tony; Foster, Scott; Parkyn, Matthew (University of ChesterUniversity of Chester, 2019-07)
      This research has explored how seventeen middle managers in the social housing sector manage employee stress and the reasons they take the approach they do. The research has been conducted in response to the increased prevalence of workplace stress. While workplace stress and mental well-being continues to rise up the political and business agenda; the most recent statistics from national and international organisations identify that the management of stress in the workplace needs to be improved. Workplace stress is a global issue for which the related direct and indirect costs are only beginning to be quantified, although the estimated cost of work-related depression in Europe is €617 billion per year. Furthermore, there is a trend towards devolving responsibility for managing workplace stress to individual managers. Despite their increasing responsibilities for managing stress at work, middle managers often lack the authority, skills and capacity to make the changes required to prevent workplace stress. Evidence suggests that middle managers are in a complex and challenging position between their superiors and more junior staff which can exposes them to role related stressors. The United Kingdom (UK) social housing sector is a particularly complex and vital one, comprising of a variety of private, public and charitable enterprises that build, manage and maintain housing stock. The complexities, political and financial challenges facing the sector expose middle managers and their staff to an increased risk of work-related stress. This study adopted a constructivist philosophy, relativist ontology and subjectivist epistemological position. Semi structured interviews were conducted with seventeen middle managers working in the social housing sector in an attempt to explore and better understand how they approach managing work-related stress experienced by the employees. The findings of this study are that, in contrast to what the extant literature recommends, participants adopt predominantly reactive approaches to managing employee stress and deploy mostly secondary and tertiary stress management interventions. The study also found that the participants tend to focus on managing stress caused by workload, relationships at work and home-work interface. Furthermore, this study contributes new insights into how middle managers are managing stress in practice such as, using their personal experiences of managing their own stress and by observing the behaviours and practices of other managers. This study also highlights a number of contemporary stressors in the context of the social housing sector. These contributions provide new practical insights into how middle managers might more effectively manage stress in the workplace. The need and focus of this research arose from the researcher’s practice as an occupational health and safety consultant working with social housing providers across the UK. His work involves advising housing providers and their middle managers on matters of employee stress and health. Often this advice is sought when the employee is already unwell and needs help to recover. This reactive approach to workplace stress is contrary to what UK health and safety (H&S) law requires and is known to be ineffective in tackling stress at work. The researcher’s professional experience in the housing sector and the trend in devolving responsibility for managing stress at work to middle managers, provided the initial spark for this research.
    • Developing active personal learning environments on smart mobile devices.

      Whalley, Brian; France, Derek; Park, Julian; mauchline, Alice; Welsh, Katharine E.; University of Sheffield, University of Chester, University of Reading
      ‘Tablets’ and other 'smart' devices (such as iPads and iPhones)have established themselves as a significant part of mobile technologies used in mobile (m-)learning. Smart devices such as iPads and the Apple Watch not only provide many apps that can be used for a variety of educational purposes; they also allow communication between students and tutors and with the world at large via social media. We argue that 'smart' mobile devices enable personalized learning by adjusting to the educational needs of individuals. We refer to Salmon's quadrat diagram to suggest where using mobile technologies should be of benefit to revising our views of pedagogy, making it much more responsive to students' needs in education as well as the world in general. Smart mobile devices now contain computing power to allow voice and face recognition, augmented reality and machine learning to make them intelligent enough to act as tutors for individual students and adjust and respond accordingly. To take advantage of these facilities on mobile devices, pedagogy must change from an institution-centred to a student-tutor-device focus. This is best done via 'active learning' and incorporating cognitive awareness into an educational operating system that can develop with the owner.
    • “The Great Story on Which the Plot Turns”: Cruciformity in C.S. Lewis’ Narrative Spiritual Theology

      Dickieson, Brenton (University of ChesterUniversity of Chester, 2019-05)
      This thesis presses in on C.S. Lewis’ extremely diverse corpus to explore his integrative narrative spirituality of the cross. Chapter one argues that Lewis’ concept of spiritual self-death and resurrection is lacking critical treatment despite the spirituality of the cross that I argue is deeply woven into the fabric of Lewis’ poetry, fiction, nonfiction, and letters. This cross-shaped spirituality, what Michael Gorman calls “cruciformity,” is central to Lewis’ understanding of Christian life. Though neglected because of readings of Lewis that reduce him to the role of an apologist, chapter one surveys occasional notes about this death-and-resurrection motif in Lewis scholarship and provides definitions for methodological approaches to the study. Following definitions of spiritual theology by Eugene Peterson, chapter two turns from systematic theological explorations of Lewis to consider him as a spiritual theologian, a move that is organic to his theological enterprise, his epistemology, and his fiction. Chapter three explores Gorman’s biblical-theological approach to Pauline cruciformity, arguing that there is a six-point Logic of Cruciformity in Lewis’ so-called apologetics writings that moves past and refocuses Thomas à Kempis’ Imitation of Christ. As Lewis’ spirituality is embedded in narrative form within poetry, fiction, and nonfiction, chapter four explores “The Shape of Cruciformity” in Lewis’ œuvre, using Northrop Frye’s narratology and J.R.R. Tolkien’s theory of eucatastrophe to argue that there is a comedic, U-shaped pattern of cruciform imagery in Lewis’ fiction, poetry, and nonfiction. Chapter five interrogates Lewis’ integrative, normative narrative cruciformity with feminist theological critique, provoked by Anna Fisk’s concerns about cross-shaped spiritualities in women’s experiences. A response to this problematisation reveals an inversive quality inherent to Lewis’ thought that is itself U-shaped, comedic, and eucatastrophic. Chapter six explores this inversive U-shaped thinking central to Lewis’ theological project, arguing that the shape of cruciformity in Lewis is the shape of his spiritual theology. I conclude the thesis with “sacred paradoxes” in Lewis’ thought that invite further work and deepen our understanding of Lewis’ concept of spiritual life, thus inviting a prophetic self-critique for Christian believers.
    • Predictors of mortality and survival in type 1 diabetes: a retrospective cohort study of type 1 diabetes mellitus (T1D) in the Wirral Peninsula

      Akata, Eloho (University of ChesterUniversity of Chester, 2019-05)
      Background: The prevalence of T1D is rising, despite improvements in the management of this condition. It presents a risk of premature and excess mortality, which impacts survival and life expectancy. Aim: The study aim was to assess mortality, identify predicting risk factors for mortality and survival in T1D in the Wirral. A systematic review was done to establish present current evidence of all-cause and cause-specific mortality amongst T1D patients. Methods: A retrospective cohort study design, 1786 patients diagnosed with T1D extracted from the Wirral Diabetes Register (WDR). The follow-up period was between 1st of January, 2000 to 31st December, 2012. The primary outcome measured was all-cause mortality. Results: 1458 participants with T1D meet the inclusion criteria, after a follow-up period of 12 years, 113(7.75%) deaths were recorded. While the incidence rate was steady over the study period, the prevalence rate continued to increase over the study period. Significant predictors of mortality in this cohort were age of diagnosis, duration of diabetes, HbA1c,systolic blood pressure (SBP), diastolic blood pressure (DBP), and triglyceride levels. The predicting risk gender, age at diagnosis, duration of T1D, BMI, serum creatinine levels, SBP, total cholesterol, LDL, HDL, TC\HDL, and LDL\HDL showed a linear increase in mortality risk. IMD and DBP followed a U-shaped relationship with relative and absolute mortality, while HbA1c levels reveal a sinusoidal pattern with the highest risk of mortality at the levels ≤ 5.9% (41 mmol/mol). The risk of mortality for the predicting risk factors for this study ranged between 5% and 9%. Maximal risk of mortality of 9% was recorded in the predicting risks of smoking, BMI, SBP, and DBP. The risk of mortality of 8% was recorded for IMD, serum creatinine, total cholesterol, TG, LDL\HDL ratio, and TSH. The risk of mortality of 7% was recorded for the predicting variables of HbA1c, HDL, LDL, and TC\HDL ratio. The minimum risk of mortality of 5% was recorded for the predictor variable of the duration of diabetes. The significant predictors of mortality were the age at diagnosis, duration of diagnosis, systolic and diastolic blood pressure, HbA1c. The burden of mortality rest disproportionately with females who had higher relative risk of mortality of 4 times that of their male counterparts, however, the burden of premature mortality as recorded by the years of potential life lost was slightly higher in males (1797[53.6%]) as compare to females (1553[46.4%]). Of the 113 deaths recorded for the cohort that indicated a proportion of 7.75% of the total T1D patients, records for only 37 participants were retrieved. The principal cause of death in this cohort was malignancy-related 8 deaths (21.6%), this was followed by cardiovascular disease and sepsis, each having 6 deaths (16.2%) respectively. Cerebrovascular disease accounted for 5 deaths (13.5%). Death from diabetes complications (hypoglycaemia) was recorded in 1 patient (2.7%). There were marked reductions in life expectancy for this cohort. Life expectancy at 40 years for females was to an average age mortality of 66.2 years as compared to males 78.3 years. There has been improved survival for T1D in this cohort, 77.185 years [95% CI: 75.191 – 79.179] in males and 76.011 years [95% CI: 73.169 – 78.000] in females. The systematic review highlighted increased mortality in those with T1D as compared to the general population, females showed greater risk of vascular complications as compared to the males with T1D. 35 studies were included. Results showed all-cause mortality RR 3.73 (95% CI 3.19, 4.36) compared to general population, with gender specific mortality RR 1.17 (95% CI 1.06, 1.29). For cause specific mortality risk (overall and gender specific): cardiovascular v disease RR 3.48 (95% CI 3.14, 3.86) and RR 1.41 (95% CI 0.92, 2.17); renal disease RR 1.06 (95% CI 0.89, 1.26) and RR 0.63 (95% CI 0.38, 1.04); neoplasms RR 1.03 (95% CI 0.92, 1.16) and RR 1.18 (95% CI 0.75, 1.86); cerebrovascular disease according to gender RR 0.99 (95% CI 0.66, 1.48), and accidents and suicides according to gender RR 2.30 (95% CI 1.31, 4.06). Conclusion In conclusion, the study highlighted significant mortality risk in females as compared to their male counterparts; there has been progress in the survival of patients with T1D. However, life expectancy remains reduced as compared to those without the condition. Prevalence of T1D continues to increase, and the complex interplay of the predictor variables support the need for an individualised approach to care.

      The purpose of this paper is to investigate the fault coupling effects in the planet bearing as well as the corresponding vibration signatures in the resultant vibration spectrum. In a planetary gear application, the planet bearing can not only spin around the planet gear axis, but also revolve about the sun gear axis and this rotating mechanism poses a big challenge for the diagnostic analysis of the planet bearing vibration spectrum. In addition, the frequency component interaction and overlap phenomenon in the vibration spectrum caused by the fault coupling effect can even worsen the diagnosis results. To further the understanding of the fault coupling effects in a planet bearing, a 34° of freedom planetary gear model with detailed planet bearing model was established to obtain the dynamic response in the presence of various bearing fault scenarios. The method of modelling the bearing distributed faults and localized faults has been introduced in this paper, which can be further incorporated into the planetary gear model to obtain the faulted vibration signal. The “benchmark” method has been adopted to enhance the planet bearing fault impulses in the vibration signals and in total, the amplitude demodulation results from 20 planet bearing fault scenarios have been investigated and analyzed. The coherence estimation over the vibration frequency domain has been proposed as a tool to quantify the fault impact contribution from different fault modes and the results suggested that the outer raceway fault contributes most to the resultant planet bearing vibration spectrum in all the investigated fault scenarios.
    • Innovative Pedagogies

      We scope eight innovative pedagogies that have the potential to provoke major shifts in teaching, learning, and assessment in geography at the undergraduate level. There are further opportunities for geography educators to embrace newly emerging pedagogies to the positive benefit of students, staff, and the health of the discipline. The next decade of higher education geographical pedagogy might focus less on individual elements of our practice and more on how to integrate latent pedagogies into an effective process for future-facing lifelong learning, which might be achieved by focusing on heutagogy in borderland spaces of learning; bringing together a multiplicity of geography and other disciplinary students over diverse spaces and times to co-construct understanding dialogically, allowing them to determine their own learning needs, and preparing them to be successful citizens in a dynamic and uncertain future.
