    • Developing framework for improving the Nigerian public sector construction projects selection processes

      Unuafe, Emmanuel (University of BedfordshireUniversity of Bedfordshire, 2017-06-16)
      Despite the development of various frameworks to assist in the appraisal and selection of government projects, failures are still being recorded with government projects. In developing countries, where frameworks are rarely used, the problems are compounded. To improve the situation this study investigates the current practice of construction project selection processes within the Nigerian public sector in order to inform theories of decision making from the perspective of developing nations and project management practice. The study adopts approach that challenges the concepts of conventional scholars. More specifically, it adopts Activity Theory concepts in the development of a conceptual framework. Data were collected through semi-structured interviews with a purposeful sample of 30 senior public sector management personnel within the five parallel case organisations between March 2015 and November 2017. The data obtained from the interviews were then compiled and analysed using qualitative software for content analysis. Using activity theory as the basis of the investigation, the findings identified a number of artefacts mediating project selection activity. Findings revealed that with the increase in population, incidence of infrastructure shortage has continued to increase in Nigeria, causing a severe challenge, especially to the Nigerian government. The citizens now depend largely on dilapidated and/or in some instances on low quality infrastructure and feel strongly that the shortage in infrastructure supply capacity and the rate of marginalisation of some regions in the provision of infrastructure is pushing the country towards disaster. This feeling is compounded by the fact that the majority of government projects have not delivered the anticipated benefits within time and cost expectations. A number of factors were identified as influencing the project selection process within the public sector and these have been grouped under six categories: technical factors, stakeholders’ expectation factors, financial feasibility factors, social factors, strategic alignment factors and external factors. Findings emerging from this study reveal that a visible theoretical project selection framework to support public sector decision makers in making project decisions is still lacking. The thesis concludes by proposing a selection framework and guidelines/protocols that will aid decision makers to be consistent in assessing and selecting construction projects within the Nigerian public sector. The results from this study also indicate that the level of stakeholder participation is still low. This study supports positive stakeholder engagement by informing decision-maker the need to adopt bottom-up approach where stakeholders drive the project selection process rather than the top-down approach where the executive drives project selection process as is currently the practice in Nigeria.
    • An examination of the recontextualisation of national sport policy when implemented into practice: a case study of Sport England’s ‘This Girl Can’

      Price, Rianna (University of Bedfordshire, 2016-11-04)
      The purpose of this study is to investigate the recontextualisation of a sport policy into the local level, through a case study of Sport England’s ‘This Girl Can’ (TGC) campaign in order to examine the implementation gap currently in UK sport policy. Bernstein’s pedagogical approach (1996) is used as the theoretical framework to analyse how intended outcomes are not implemented in practice. A Case Study research design facilitated the use of multiple qualitative methods: semistructured interviews (n=7) with participants in the field of Sport Development. They were asked to share their perspectives on policy and delivery, specifically TGC, and their experiences of delivery ‘on the ground’. An online questionnaire gathered information about respondents’ (n=41) sport and PA participation and their experience of TGC. Analysis of the data was conducted using a combination of content and thematic analysis. The research findings indicate that there is an implementation gap in sport policy to practice regarding TGC. The intention of the TGC campaign was to encourage women to think differently about sport and PA, in part through a model of behaviour change. Sport England claims that the campaign had an impressive influence as a result of the use of television and public space advertisements which enhanced public and media attention. At a local level, however, national organisations (such as Sport England) failed to facilitate development of the knowledge or resources required by practitioners to effectively implement the strategy. Provider’s recontextulaised the policy to fit their understanding or the needs in their local environment and in so doing did not follow the intentions of TGC. It is essential that the relationship between the national (policy makers) and local (implementation) be rebuilt in order for sport policies, campaigns and programmes to be more effective and suit the needs and resources available for practitioners. Rebranded solutions may be provided for recurring problems, where the implementation gap affects policy being accurately implemented because there is limited connection with specific needs on the ground.
    • Help-seeking for perinatal mental health: South Asian women’s experiences in Luton

      Moghul, Fariha (University of Bedfordshire, 2018-09-06)
      The objective was to identify the current care pathway for Perinatal Mental Health (PMH) in Luton, and to explore South Asian women’s views on factors that influence help-seeking with a view to making recommendations to local service development (LBC, BLMK). Method Focus groups were used to explore the factors (barriers and enablers) that influenced the help-seeking of local South Asian women for perinatal mental health. 5 focus groups (FG) were conducted with n=17 women, from various South Asian countries and ethnic subgroups, all of whom had children who had been born locally. Luton has a large ethnic population in areas of high social and material deprivation, with a fast growing birth rate, placing them at increased risk of perinatal mental illness (PMI), but conversely has low levels of reported mental illness from within these areas. Findings The findings indicate that community; extended family, religious and cultural beliefs have a significant impact on the development, recognition and treatment of PMI, forming a complicated mesh of considerations that need to be integrated when designing local PMH services for differing populations. Conclusion Improving healthcare engagement may require a three pronged approach of; developing more culturally attuned services; a community social awareness programme endorsed by community leaders and; a socio-healthcare programme to sustain healthy spousal and familial relationships and change cultural attitudes towards motherhood to help prevent the development of PMI. These changes may reduce stress in the post-partum year, where caring for a new baby means that illnesses are more likely to develop and contribute to healthy and positive family relationships, with long-term health, social and life trajectory benefits for the family, community and society in general.
    • Revisiting the Black-Scholes model related to the volatility assumptions

      Chiwele, Chansa (University of BedfordshireUniversity of Bedfordshire, 2017-06-02)
      The Black-Scholes (BS) or Black-Scholes-Merton (BSM) formula is the most popular model that is used to price vanilla options. However, some of the assumptions underpinning this formula have been found to be false (Dumas, 1998). One such assumption is stated below: “There are no transaction costs on the underlying asset” (Wilmott, 2006). This assumption advances the idea that markets are frictionless and therefore there are no transaction costs incurred in those markets. This in fact is not true. It is costly to carry out financial transactions in financial markets. Taxes are normally applied to transactions that take place in various financial jurisdictions (Wilmott, 2006). One other BS assumption says that “there is a single constant volatility for the stochastic pro-cess followed by the spot” (Austing, 2014). If the world were truly BS in nature, the volatility quoted for each of the options with different strike prices in a liquid market would be the same (Austing, 2014), (Kwok, 2008). In other words, if the implied volatility quotes were plotted against the strike prices, a straight horizontal line would be obtained (Austing, 2014). However, after the financial crisis of October 1987, it was discovered that when the Implied Volatilities (IV) of a group of vanilla options of the same maturity were plotted against strike prices, the graph had the shape of a smile (Dupire, 1994). This is called the volatility smile. This was not expected. The shape of the graph that was expected was that of a straight hori-zontal line. The above issues and others have resulted in the values of options that are calculated by the BS not being fully accurate. This has created a gap in the body of published literature which needs to be filled. In addition to the above issues, another of the inaccuracies in the BS has been attributed to the IV parameter. All the parameters that are input into the BS formula are observable except the IV (Kwok, 2008), (Wilmott, 2006), (Dupire, 1994). Therefore, those parameters that are observable can have their values determined accurately from observable evidence whereas the value of the IV does not enjoy this privilege. In fact, the IV is normally determined by the sentiment of the financial markets. This is not very accurate. The quest of this research is to develop a mathematical model that would determine the values of the IVs more exactly which can be used to obtain more accurate results from the BS formula. This approach will be unique and has not been evidenced in literature. It will help to fill the gap that currently exists in the body of knowledge. The idea is to use this mathematical model to calculate more precise values of the IV which will be input into the BS formula in order to improve the accuracy of the BS formula. The secondary benefit from the approach taken by this research is being able to determine the strike prices that match the given IVs. Sometimes the strike prices agreed upon by the market participants can be out of kilter with the other parameters in the BS formula. This re-search would be able to help resolve that.
    • ‘Y el olor de la sangre manchaba el aire’: Tlatelolco 1521 and 1968 in José Emilio Pacheco’s ‘Lectura de los “Cantares Mexicanos”’

      Carpenter, Victoria; (Liverpool University Press, 2018-12-31)
      When Octavio Paz compared the Tlatelolco 1968 massacre to the conquest of the Aztec empire he created a foundation (and indeed, at times, the inspiration) for the view of the massacre as a symbol of a long-lasting internal conflict. This paper explores how the Tlatelolco 1968 poetry reflects (or appropriates) the 1521 texts. Are these texts used as extra metaphors of what happened in La Plaza de las Tres Culturas on 2 October, as links to the square’s infamous past, or is there a more enduring reason for the retelling of the story of the fall of Tenochtitlán? To answer these questions, I will examine four versions of José Emilio Pacheco’s poem ‘Lectura de los “Cantares Mexicanos”: Manuscrito de Tlatelolco (octubre 1968)’. The reading will be informed by the theory of habit (Bourdieu) and collective remembering and forgetting (Halbwachs and Bartlett).
    • A bridge between worlds: parallel universes and the observer in “The Celestial Plot” by Adolfo Bioy Casares

      Carpenter, Victoria; Halpern, Paul; University of Bedfordshire; University of the Sciences, Philadelphia (Brill Academic Publishers, 2019-09-24)
      Adolfo Bioy Casares’s story “The Celestial Plot” (1948) is among the best known examples of Latin American science fiction writing of the early twentieth century inspired by contemporary advances in quantum physics. Most readings of the story focus on the movements of its main protagonist, Captain Ireneo Morris, as he traverses realities while test-flying a plane. This approach overlooks the role of the story’s other protagonist, Dr. Carlos Servian, who, we argue, is the lynchpin upon which the multiple realities are dependent. We read the changes to Dr. Servian’s character from a variety of scientific and philosophical perspectives on parallel universes. By addressing variations in Servian’s character and language, and focusing on the disparate representations of the key objects in the story, we show how the story anticipates in some ways the Many Worlds notion which argues that reality bifurcates during quantum measurements, leading to near-identical copies of observers.
    • Recent advances in sensor fault diagnosis: a review

      Li, Daoliang; Wang, Ying; Wang, Jinxing; Wang, Cong; Duan, Yanqing; China Agricultural University; Shandong Agricultural University; University of Bedfordshire (Elsevier, 2020-05-11)
      As an essential component of data acquisition systems, sensors have been widely used, especially in industrial and agricultural sectors. However, sensors are also prone to faults due to their harsh working environment. Therefore, the early identification of sensor faults is critical for making corrective actions to mitigate the impact. This paper provides a comprehensive review on the contemporary fault diagnosis techniques and helps researchers and practitioners to understand the current state of the art development in this emerging field. The paper introduces the common fault types and causes in sensors, and different types’ methods for fault diagnosis used in industry and agriculture sectors. It discusses the advantages and disadvantages of these methods, highlights the current challenges, and offers recommendations for future research directions.
    • Explaining work-related stress in UK academic staff: alternative approaches

      Wray, Siobhan (University of BedfordshireUniversity of Bedfordshire, 2018-09-26)
      The programme of work presented in this thesis examined the effect of work-related stressors in UK academic staff across a period of six years, utilising a benchmarking approach. Furthermore, the thesis examines the relationships between stressors and a range of key strain outcomes: psychological distress, emotional exhaustion, disengagement, work-life conflict, intrinsic and extrinsic job satisfaction. Study 1 presents the results of three work and wellbeing surveys conducted in 2008, 2012 and 2014 that utilise the Health and Safety Executive’s Management Standards Indicator tool to assess levels of psychosocial hazard in the occupational group at these three time points. Comparisons were made across each wave of data to identify patterns of change in the sector. Additionally, a range of strain outcomes were assessed at each data collection point and examined with reference to other occupational groups and norms, and across the waves of data where appropriate. The results from study 1 indicate that the level of wellbeing associated with academic work significantly reduced in five out of seven hazard categories across the three waves of data. Additionally, academic staff reported higher levels of perceived stress and increased work-life conflict. Psychological distress and job satisfaction, measured in 2014, were lower than benchmarked data from a range of other occupational groups. Study 2 examined the predictive power of two key theoretical models of work-related stress to further examine the stressor-strain relationship in academic staff. The job demands control-support and job demands resources models predicted significant proportions of the variance in all strain outcomes, however, the inclusion of a broader range of resources in the latter model explained a greater proportion of the variance in all outcome measures except work-life conflict. Strong main effects were observed in each model, but the evidence for interactive effects was less conclusive. Study 3 expanded on these findings by examining key resources identified in the job demands resources model and examining these via the context of sector change. A conservation of resources approach was used to develop and test a resource caravan whereby satisfaction with sector change predicted strain outcomes via the mediating effects of role stress and two form of illegitimate task. Indirect effects of role and illegitimate tasks independently mediated the relationship between change on a range of outcome variables, Additionally, a serial mediation effect whereby change predicted role, which in turn predicted illegitimate tasks added further unique predictive power to each model. The findings from the thesis indicate a worsening pattern of wellbeing associated with academic work across the six-year period investigated and evidence is presented to support the effect of stressors on key strain outcomes in academic staff. Finally, the findings highlight the importance of examining the relationships between key resources at sector, institutional and individual levels to inform systemic interventions to respond to the significant levels of stressors and strain reported by the sector and suggestions for interventions are discussed.
    • An oral history of health psychology in the UK

      Quinn, Francis; Chater, Angel M.; Morrison, Val (Wiley, 2020-04-20)
      Abstract Purpose An oral history of the development of health psychology in the United Kingdom. Methods Standard oral history methods produced interviews with 53 UK health psychologists, averaging 92 min in length. All interviewees entered the field from the 1970s to the 2000s, representing all four countries in the United Kingdom. A reconstructive mode of analysis, along with the few existing sources, was used to create a narrative of the history of health psychology in the United Kingdom. Audio recordings and transcripts will be archived for use by future researchers. Findings In the 1970s, medical schools in London recruited psychologists to teach, while also conducting pragmatic research on issues in healthcare. At the same time, some clinical psychologists began to work with physical health conditions in general hospitals. Partly influenced by developments in the United States and Europe, an identity of ‘health psychology’ developed and spread to researchers and practitioners doing work in psychology and health. In the 1980s, the field continued to attract researchers, including social psychologists working with health behaviours and outcomes, and clinical psychologists working in health care settings. During this time, it became formalized as a scientific field with the creation of the BPS Health Psychology Section, courses, and journals. In the 1990s, the field moved towards professional practice, which was controversial with other BPS divisions. However, it continued to grow and develop through the 2000s and 2010s. Conclusion Reflections on the development of UK health psychology represent the first historical narrative produced from oral testimony of those who were present at the time.
    • Safeguarding adult reviews: informing and enriching policy and practice on self-neglect

      Preston-Shoot, Michael; (Emerald, 2020-04-25)
      Purpose – One purpose is to update the core dataset of self-neglect safeguarding adult reviews and accompanying thematic analysis. A second purpose is to explore the degree to which safeguarding adult reviews draw upon available research and learning from other completed reviews. Design/methodology/approach – Further published reviews are added to the core dataset, mainly drawn from the web sites of Safeguarding Adults Boards. Thematic analysis is updated using the four domains employed previously. The four domains and the thematic analysis are rounded in the evidence-based model of good practice, reported in this journal previously. Multiple exclusion homelessness and alcohol misuse are prominent in this sample of reviews. Findings – Familiar findings emerge from the thematic analysis and reinforce the evidence-base of good practice with individuals who self-neglect and for policies and procedures with which to support those practitioners working with such cases. Multiple exclusion homelessness emerges as a subset within this sample, demonstrating that SABs are engaging in reviews of people who die on the streets or in temporary accommodation.   Research limitations/implications – The national database of reviews commissioned by SABs remains incomplete and does not contain many of the safeguarding adult reviews reported in this evolving dataset. The Care Act 2014 does not require publication of reports but only a summary of findings and recommendations in SAB annual reports. NHS Digital annual datasets do not enable identification of reviews by types of abuse and neglect. It is possible, therefore, that this dataset is also incomplete. Drawing together the findings from the reviews nonetheless builds on what is known about the components of effective practice, and effective policy and organisational arrangements for practice. Practical implications – Answering the question “why” remains a significant challenge for safeguarding adult reviews. The findings confirm the relevance of the evidence-base for effective practice but SARs are limited in their analysis of what enables and what obstructs the components of best practice. Greater explicit use of research and other published SARs might assist with answering the “why” question, drawing attention where appropriate to policies being pursued by central government that undermine any initiative to end rough sleeping. Originality/value – The paper extends the thematic analysis of available reviews that focus on work with adults who self-neglect, further reinforcing the evidence base for practice. The evidence-base also supports practice with individuals who experience multiple exclusion homelessness. Policy-makers and practitioners have an approach to follow in this complex, challenging and demanding area of practice.   Keywords: Safeguarding adult reviews, evidence, self-neglect, research, multiple exclusion homelessness, alcohol misuse
    • Capturing debriefing and enhancing reflection within simulated clinical learning environments

      Wareing, Mark; England, Jacqueline A.; Mathew, David; Ball, Carla; Willetts, Amanda; Kemp, Jane; Clifford, Kelly; Thompson, Andrea; Dove, Ian; Adams, Louise; et al. (National Association of Educators in Practice, 2020-05-05)
      This article presents findings from an evaluation of a new A3-size learner notes sheet designed for use by healthcare students engaging in clinical simulation and clinical skills sessions. The notes sheet consists of an adapted form of the SBAR (situation, background, assessment, response) tool, whilst capturing post-simulation oral debriefing provided by a facilitator. Additionally, the Driscoll (2007) model is used to provide students with an opportunity to reflect on their engagement in clinical simulation. Two cohorts of students, who engaged in separate simulation sessions, completed the A3 sheet. The study featured 33 midwifery and 21 operating department practitioner (ODP) students undertaking a simulation. Documentary analysis was undertaken to identify the depth of reflective writing of both groups of students. Midwifery student participants reflected on their experiences of simulation at a slightly deeper level than their ODP counterparts. All students adhered to the structure of the notes sheet when receiving their briefing from the facilitator and when asked to write their reflective accounts. This study has sought to explore an under-researched area of clinical simulation: the extent to which healthcare students can utilise reflection when engaging with a clinical scenario within a simulated learning environment.
    • Best practices in the cost engineering of through-life engineering services in Life Cycle Costing (LCC) and Design To Cost (DTC)

      Baguley, Paul (Springer, 2020-04-30)
      This chapter defines a number of Cost Engineering challenges from industry and their potential best practice solutions as industry case studies and industry practices surveys completed during the previous 5 years. In particular Life Cycle Costing in the context of upgrade and revamp in the process industry and also an example of design for full life cycle target cost for the manufacturing industry. Life Cycle Costing of complex long life cycle facilities is exemplified by identification and development of a life cycle costing of oil refineries through a survey of 15 companies and full life cycle experts and a review of the literature. Life cycle costing practices and a standardised life cycle cost breakdown structure are identified. Design to full life cycle target cost practices have been identified in the development of a full life cycle cost estimating tool for marine radar systems. In particular a survey of 17 companies and a case study with a marine radar systems company has identified specific practices useful in developing products to full life cycle target cost. In planning for future Through Life Engineering Services it is proposed that the collection of cost data and the understanding of Cost Engineering practices is a potential competitive advantage.
    • Acute effects of breaking up prolonged sedentary time on cardiovascular disease risk markers in adults with paraplegia

      Bailey, Daniel Paul; Withers, Thomas M.; Goosey-Tolfrey, Victoria L.; Dunstan, David W.; Leicht, Christof A.; Champion, Rachael B.; Charlett, Opie P.; Ferrandino, Louise; (John Wiley and Sons, 2020-04-03)
      Elevated levels of cardiovascular disease (CVD) risk markers are highly prevalent in people with a spinal cord injury (SCI). Breaking up prolonged sedentary time with short, regular bouts of physical activity can reduce postprandial glucose and lipid levels in able-bodied individuals. The effects in people with paraplegia are unknown. The study aims were to examine the acute postprandial glucose (primary aim), lipid, blood pressure, and psychological responses (secondary aims) to breaking up prolonged sedentary time in individuals with paraplegia. This was a randomized crossover design trial. Fourteen participants with paraplegia (age 51 +- 9 years, trunk fat mass 44.3 +- 7.7%) took part in the following two, 5.5-hour conditions: (1) uninterrupted sedentary time (SED), and (2) sedentary time interrupted with 2 minutes of moderate-intensity arm crank ergometer physical activity every 20 minutes (SEDACT). Standardized breakfast and lunch test meals were consumed during each condition. The outcomes were compared between conditions using linear mixed models. Glucose area under the curve (AUC) was significantly lower during the lunch postprandial period in SED-ACT vs SED (incremental AUC 1.9 [95% CI 1.0, 2.7) and 3.0 [2.1, 3.9] mmol/L∙2.5 hour, respectively, P = .015, f = 0.34). There were no differences between conditions for the breakfast or total 5.5 hours postprandial periods (P > .05). Positive affect was higher in SED-ACT than SED (P = .001). Breaking up prolonged sedentary time acutely attenuates lunch postprandial glucose and improves positive affect in people with paraplegia. This may have clinical relevance for reducing CVD risk and improving psychological well-being in this population.
    • Two roads, one destination: community and organisational mechanisms for contextualising child abuse prevention in Australia and the UK

      Firmin, Carlene Emma; Rayment-McHugh, S.; (Springer, 2020-05-04)
      Calls for a contextual approach to abuse prevention highlight a need to better understand how contextual frameworks may be operationalized.  Using a dual-case study design, this research compares two contrasting pilot projects underpinned by contextual theories of abuse prevention.  One was implemented in a small remote Indigenous community in Australia, and aimed to reduce the extent of youth-perpetrated sexual abuse.  The other occurred in a densely populated urban area in London (United Kingdom) and involved the co-creation and testing of a contextual child protection response to peer-to-peer abuse.  Despite their divergent approaches to developing contextual practice, a comparison of the two projects identified shared features of implementation. Both involved: context-specific community buy-in and ownership of a response to peer-to-peer abuse; solutions that were co-created between professionals and communities, and; the enhancement of community guardianship, pro-social use of space and changes to the physical design of areas to increase safety. Consequentially both projects demanded a radical transformation in the way health and social care professionals viewed the target of their interventions – the what- and the approach to achieving change – the how. Comparing these two case studies provides a unique opportunity to extend knowledge on the practical application of contextual theoretical approaches to abuse prevention. 
    • Child sexual exploitation: why theory matters

      Pearce, Jenny J. (Policy Press, 2019-11-30)
      This book explores the contribution that different theoretical perspectives make to our understanding of child sexual exploitation (CSE). It addresses the ways that these theories can influence our practice with children and young people affected by CSE and offers scope to identify when and why particular approaches are adopted.  Each chapter identifies a particular theoretical approach, explains its meaning and then offers an understanding of how this can enhance our practice. Covering topics such as how structuration theory offers us  a way to move beyond simplistic binary oppositions such as ‘victim’ and ‘perpetrator’;  how discourse  analysis can illustrate how and why our understanding of CSE as a form of abuse has changed over time; how contextual safeguarding helps us to explore the importance of relationships, places and spaces outside of the home environment; how laisse-faire approaches to internet providers impact on their engagement with managing abuse on line; how lifespan development theories place adolescence in context with emotional maturation and  brain development; how psychodynamic understandings and trauma informed understandings help us to address the impact of abuse; how we can enhance ‘empathy’ through understanding its relationship with ecology and social support structures;  and how our understanding of the impact of racism, gender and disability can help understand situations faced by children affected by CSE  as well as our role in advocating for change. This work aims to ‘bring theory home’ into our everyday practice and encourages individuals, teams and agencies to consider how their work with children affected by CSE is informed and developed.
    • Towards an epistemology of media education: confronting the problems of knowledge presented by Social Realism

      Connolly, Steve M.; University of Bedfordshire (Taylor & Francis (Routledge), 2020-04-29)
      Recent debates about the status of knowledge in the school curriculum have seen the emergence of attempts to connect curriculum reform to the ideas about "powerful knowledge" articulated by Michael Young and other sociologists. This article argues that for the case of media education, and specifically its application in secondary schools - in the form of Media Studies - these ideas are not adequate to explain the epistemological principles upon which the project of media education is built. The paper takes a threefold approach to developing an epistemology of media education; firstly, by outlining existing work on the nature of knowledge in media education; secondly, by examining social realist arguments about the way that knowledge is manifested in things like school subjects and canonical knowledge and arguing that media education does not fit these manifestations; and finally by offering some alternative ideas upon which an epistemology of media education may be built
    • SOLACE: a psychosocial stigma protection intervention to improve the mental health of parents of autistic children: a feasibility randomised controlled trial

      Lodder, Annemarie; Papadopoulos, Chris; Randhawa, Gurch (Springer, 2020-04-23)
      This study presents findings from a feasibility trial, testing an 8-week psychosocial stigma protection intervention (SOLACE) designed to improve the mental health of parents of autistic children. Seventeen parents were stratified then randomly assigned to either SOLACE (n = 9) or control group (n = 8). Retention and adherence rates were excellent with minimal missing data suggesting SOLACE had good acceptability and feasibility. Quantitative analysis revealed that mental health scores had significantly improved for those who took part in SOLACE compared to no significant changes for control group participants. In addition, changes in secondary outcome measures (e.g. stigma, self-esteem and self-compassion) were in favour of SOLACE. Focus group interviews revealed that SOLACE was acceptable to parents. Results suggest that a full randomised controlled trial is warranted.
    • Uncertainty of Net Present Value calculations and the impact on applying integrated maintenance approaches to the UK rail industry

      Kirkwood, Leigh; Shehab, Essam; Baguley, Paul; Starr, Andrew; Cranfield University (Elsevier, 2015-10-27)
      The Public performance indicator (PPI) is an important Key Performance Indicator for Network Rail and monitored carefully by the organisation and their external stakeholders. Condition monitoring is of increasing interest within network rail as a suitable method for increasing asset reliability and improving the PPI metric. As condition monitoring methods are identified each will need assessment to establish the cost and benefit. Benefit can be measured in cost savings as poor PPI performance results in fines. Within many industries Net Present Value (NPV) calculations are used to determine how quickly investments will break-even. Cost-risk is a term that is used to describe the financial impact of an unexpected event (a risk). This paper outlines a more detailed approach to calculating NPV which considers the cost-risk effect of changes of the denial of service charging rate. NPV prediction is of importance when assessing when to deploy different fault detection strategies to maintenance issues, and therefore the cost-risk of the NPV calculation should be used to support asset management decisions.
    • Performance of supply chain collaboration - a simulation study

      Ramanathan, Usha; University of Bedfordshire (Elsevier, 2013-07-16)
      In the past few decades several supply chain management initiatives such as Vendor Managed Inventory, Continuous Replenishment and Collaborative Planning Forecasting and Replenishment (CPFR) have been proposed in literature to improve the performance of supply chains. But, identifying the benefits of collaboration is still a big challenge for many supply chains. Confusion around the optimum number of partners, investment in collaboration and duration of partnership are some of the barriers of healthy collaborative arrangements. To evolve competitive supply chain collaboration (SCC), all SC processes need to be assessed from time to time for evaluating the performance. In a growing field, performance measurement is highly indispensable in order to make continuous improvement; in a new field, it is equally important to check the performance to test conduciveness of SCC. In this research, collaborative performance measurement will act as a testing tool to identify conducive environment to collaborate, by the way of pinpointing areas requiring improvements before initializing collaboration. We use actual industrial data and simulation to help managerial decision-making on the number of collaborating partners, the level of investments and the involvement in supply chain processes. This approach will help the supply chains to obtain maximum benefit of collaborative relationships. The use of simulation for understanding the performance of SCC is relatively a new approach and this can be used by companies that are interested in collaboration without having to invest a huge sum of money in establishing the actual collaboration. © 2013 Elsevier Ltd.
