      Self-efficacy matches the belief that a person has that she is able to produce theresults she wants to achieve. The beliefs of self-efficacy that parents have about the baby emerge asa powerful predictor of positive parenting. Objective: this study aimed to evaluate the maternalself-efficacy behavior in hospitalized mothers and validate an instrument for measuring this conceptdeveloped and validated in England by Barnes and Adamson-Macedo, in 2007. Method: this cross-sectional exploratory study convenience cohort comprised 87 mothers of newborn babies, 26premature and 61 full-term infants. The scale Perceived Maternal Parenting Self-Efficacy (PMP S-E),which consists of 20 items that represent four subscales was tested for reliability and validity. Results:the internal consistency of the scale PAEPM reached a value of .86, the internal consistency andreliability estimates for each of the subscales also reached acceptable values. Exploratory FactorAnalysis (EFA) confirmed the validity of the construct and the scores of self-efficacy were normallydistributed for both subgroups and total sample. Conclusions: PMP S-E scale proved to be an easyapplication tool and psychometrically robust, reliable and valid for use with mothers of hospitalizednew-borns both premature as the term clinically stable. It is a reliable method of identifying mothersof babies who need more support from the hospital staff.

    • Validation of a scale for assessing social validity in mindfulness-based education programs

      López-González, L.; Herrero-Fernández, D.; Amutio, A.; Santamaría, T.; Van Gordon, William; University of Derby (Springer, 2019-03-30)
      Social validity (SV) is a concept used in intervention research and is concerned with the overall acceptability, relevance, and utility of an intervention to all intervention stakeholders. SV not only takes into account efficacy in respect of the pre-defined study outcomes, but also participants’ perceptions of the intervention as well as the wider social context in which it will be applied. There are a growing number of mindfulness-based educational programs (MBEPs) being empirically evaluated and implemented in educational settings. However, due to a lack of scientifically validated instruments that can assess SV in MBEPs, a systematic evaluation of SV in such programs has not been undertaken to date. The aim of this study was to investigate the psychometric properties of the Social Validity Scale of Mindfulness-Based Programs for Adolescents (Escala de Validez Social de Programas de Mindfulness para Adolescentes—EVSPM-A), composed of 20 items. The sample comprised 512 compulsory secondary education and high school students (mean age = 14.5; SD = 1.57) from three Spanish educational centers that had completed an MBEP known as the TREVA Program. Results The final version of the scale showed good psychometric properties and factor analyses yielded five factors: global impact-satisfaction, acceptance and viability, individual perceived effectiveness, perceived classroom climate; training feasibility, and applicability of techniques. The EVSPM-A appears to be a suitable means of assessing SV in MBEPs delivered to adolescents. Using the EVSPM-A to evaluate SV can help improve the implementation and long-term efficacy of MBEPs.

      The European Space Agency’s (ESA’s) Aerosol Climate Change Initiative (CCI) project intends to exploit the robust, long-term, global aerosol optical thickness (AOT) dataset from Europe’s satellite observations. Newly released Swansea University (SU) aerosol products include AATSR retrieval and synergy between AATSR and MERIS with a spatial resolution of 10 km. In this study, both AATSR retrieval (SU/AATSR) and AATSR/MERIS synergy retrieval (SU/synergy) products are validated globally using Aerosol Robotic Network (AERONET) observations for March, June, September, and December 2008, as suggested by the Aerosol-CCI project. The analysis includes the impacts of cloud screening, surface parameterization, and aerosol type selections for two products under different surface and atmospheric conditions. The comparison between SU/AATSR and SU/synergy shows very accurate and consistent global patterns. The global evaluation using AERONET shows that the SU/AATSR product exhibits slightly better agreement with AERONET than the SU/synergy product. SU/synergy retrieval overestimates AOT for all surface and aerosol conditions. SU/AATSR data is much more stable and has better quality; it slightly underestimates fine-mode dominated and absorbing AOTs yet slightly overestimates coarse-mode dominated and non-absorbing AOTs.

      Alder, David; Lamont-Black, J; Hamza, Omar; Jackson, C; Jones, C; University of Derby; Electrokinetic; Jacobs; Newcastle University (ICE, 2019-01-07)
      Electrokinetic method has been increasingly applied to repair infrastructure earthwork involving landslip. The work presented in this paper attempts to improve the current understanding of this innovative technique by verifying the effectiveness of Electrokinetic treatment using in-situ and laboratory testing in addition to monitoring data obtained from the first full scale project implementing this technique, which has been carried out recently for a defected embankment slope on M5- Junction 7 in the UK. The paper outlines the design and implementation aspects of the project and discusses the findings of the post construction verification.
    • A validation of security determinants model for cloud adoption in Saudi organisations’ context

      Alassafi, Madini O.; Atlam, Hany F.; Alshdadi, Abdulrahman A.; Alzahrani, Abdullah I.; AlGhamdi, Rayed A.; Buhari, Seyed M.; University of Southampton (Springer, 2019-08-30)
      Governments across the world are starting to make a dynamic shift to cloud computing so as to increase efficiency. Although, the cloud technology brings various benefits for government organisations, including flexibility and low cost, adopting it with the existing system is not an easy task. In this regard, the most significant challenge to any government agency is security concern. Our previous study focused to identify security factors that influence decision of government organisations to adopt cloud. This research enhances the previous work by investigating on the impact of various independent security related factors on the adopted security taxonomy based on critical ratio, standard error and significance levels. Data was collected from IT and security experts in the government organisations of Saudi Arabia. The Analysis of Moment Structures (AMOS) tool was used in this research for data analysis. Critical ratio reveals the importance of Security Benefits, Risks and Awareness Taxonomies on cloud adoption. Also, most of the exogenous variables had strong and positive relationships with their fellow exogenous variables. In future, this taxonomy model can also be applied for studying the adoption of new IT innovations whose IT architecture is similar to that of the cloud.
    • Validation of the actuator line method for simulating flow through a horizontal axis tidal stream turbine by comparison with measurements

      Baba-Ahmadi, Mohammad H.; Dong, Ping; University of Dundee; University of Liverpool (Elsevier, 2017-05-20)
      The purpose of the present work is to evaluate the capability of the Actuator Line Method (ALM) to simulate flow through a horizontal axis tidal stream turbine. A numerical model combining the ALM with large eddy simulation technique is developed and applied to compute the flow past a laboratory-scale tidal stream turbine. The flow field is analysed in terms of streamwise mean velocity, turbulence intensity, turbulent kinetic energy and the decay rate of the maximum turbulent kinetic energy behind the turbine. It is found that the ALM performs well in predicting the mean flow and turbulence characteristics behind the turbine. The flow field predicted show a clear transition from an organised vorticity region near the turbine to a highly turbulent flow downstream. The location of this transition and the controlling parameters are discussed but further investigation, both numerical and experimental is required in order to clarify its effects on the flow structure and the performance of downstream turbines in tidal turbine arrays.
    • Validation of the English version of the scale for psychosocial factors in food allergy and the relationship with mental health, quality of life, and self-efficacy

      Knibb, Rebecca C.; Cortes, Aaron; Barnes, Christopher; Stalker, Carol; Aston University; University of Derby; Universidad de Chile Clinical Hospital (2016-08-21)
      Background. The Scale for Psychosocial Factors in Food Allergy (SPS-FA) is based on the biopsychosocial model of health and was developed and validated in Chile to measure the interaction between psychological variables and allergy symptoms in the child. We sought to validate this scale in an English speaking population and explore its relationship with parental quality of life, self-efficacy, and mental health. Methods. Parents (𝑛 = 434) from the general population in the UK, who had a child with a clinical diagnosis of food allergy, completed the SPS-FA and validated scales on food allergy specific parental quality of life (QoL), parental self-efficacy, and general mental health. Findings. The SPS-FA had good internal consistency (alphas = .61–.86). Higher scores on the SPS-FA significantly correlated with poorer parental QoL, self-efficacy, and mental health. All predictors explained 57% of the variance in SPS-FA scores with QoL as the biggest predictor (𝛽 = .52). Discussion. The SPS-FA is a valid scale for use in the UK and provides a holistic view of the impact of food allergy on the family. In conjunction with health-related QoL measures, it can be used by health care practitioners to target care for patients and evaluate psychological interventions for improvement of food allergy management.
    • Validation of the HADRIAN system using an ATM evaluation case study

      Summerskill, Steve; Marshall, Russell; Case, Keith; Gyi, Diane E.; Sims, Ruth; Davis, Peter; Day, Philip N.; Rohan, C.; Birnie, S.; Loughborough University (2010)
      The HADRIAN human modelling system is under development as part of the EPSRC funded AUNT-SUE project. The HADRIAN system aims to foster a 'design for all' ethos by allowing ergonomists and designers to see the effects of different kinds of disability on the physical capabilities of elderly and people with disabilities. This system is based upon the long established SAMMIE system, and uses data collected from 102 people, 79 of whom are registered as disabled, or have age related mobility issues. The HADRIAN system allows three dimensional CAD data of new products to be imported, with a subsequent automated analysis using all of the 102 sample members. The following paper describes the process and results gathered from a validation study using an ATM design as a case study. The results indicated that fine tuning of the behavioural data built into HADRIAN would improve the accuracy of an automated product analysis.

    • Validity of the Polar V800 heart rate monitor to measure RR intervals at rest

      Neil, William; Giles, David; Draper, Nick; University of Derby (Springer, 2015-12-26)
      Purpose To assess the validity of RR intervals and short-term heart rate variability (HRV) data obtained from the Polar V800 heart rate monitor, in comparison to an electrocardiograph (ECG). Method Twenty participants completed an active orthostatic test using the V800 and ECG. An improved method for the identification and correction of RR intervals was employed prior to HRV analysis. Agreement of the data was assessed using intra-class correlation coefficients (ICC), Bland–Altman limits of agreement (LoA), and effect size (ES). Results A small number of errors were detected between ECG and Polar RR signal, with a combined error rate of 0.086 %. The RR intervals from ECG to V800 were significantly different, but with small ES for both supine corrected and standing corrected data (ES <0.001). The bias (LoA) were 0.06 (−4.33 to 4.45 ms) and 0.59 (−1.70 to 2.87 ms) for supine and standing intervals, respectively. The ICC was >0.999 for both supine and standing corrected intervals. When analysed with the same HRV software no significant differences were observed in any HRV parameters, for either supine or standing; the data displayed small bias and tight LoA, strong ICC (>0.99) and small ES (≤0.029). Conclusions The V800 improves over previous Polar models, with narrower LoA, stronger ICC and smaller ES for both the RR intervals and HRV parameters. The findings support the validity of the Polar V800 and its ability to produce RR interval recordings consistent with an ECG. In addition, HRV parameters derived from these recordings are also highly comparable.
    • Value chain impacts of EU waste framework directive 2018/851 as a result of reporting substances of very high concern from 2021

      Takhar, Sukhraj; Liyanage, Kapila; College of Engineering and Technology, University of Derby; Assent Compliance, Canada (University of Cambridge, 2019-09-27)
      The EU Waste Framework Directive 2018/851 sets out requirements for producers and importers of products within the EEA, to report data on Substances of Very High Concern (SVHC) content within products into a new central European database to from 5th January 2021. The reporting requirements: (1) support chemical regulations that impose the need on industry to record the use of hazardous chemicals; (2) identification of products entering waste streams containing hazardous chemicals; (3) support circular economy initiatives within the EU. To meet these new reporting requirements industry will need to collect additional information from all supply chain actors, who as duty holders will also be required to report into the new EU SVHC database system. Failure to provide the required information may result in enforcement actions from the authorities, which could see products being restricted from the EEA. The new EU database system will be accessible to industry, regulators, NGOs and the general public. This paper explores the new requirements, together with feedback received from various stakeholders for collection of data and reporting into the new EU database system from 2021.
    • Value co-creation and co-destruction: considerations of spa servicescapes

      Buxton, Louise; Michopoulou, Eleni; University of Derby (Informa UK Limited, 2021-01-19)
      Spas are places that enable mind, body and spiritual harmony, and are therefore inextricably linked to the pursuit of health and wellbeing, as one of the most prominent forms of wellness tourism. Recent growth in the global spa industry is fuelled by increasing consumer interest in the pursuit of wellness. Concepts within the spa industry remain largely unexplored, thus, this conceptual paper aims to progress our understanding by considering opportunities for value co-creation and co-destruction in a spa context. In doing this, the paper unpacks the concept of the servicescape, explores the concept of authenticity and argues that understanding the consumption and production of experiences is central to understanding the creation of value in spa service settings.

    • 'Value for money' and the restaurant experience: a case study of supply and demand stakeholders.

      Alonso, Abel Duarte; Sakellarios, Nikolaos; Jones, Chris; Cseh, Leonard; Cooper, Sandra J.; Edith Cowan University; University of Derby (Inderscience Publishers, 2016-06-18)
      Using the case of a training restaurant open to paying guests, this study compares the perceptions of two groups of stakeholders with regard to different factors of the dining experience. The first group represents the supply side and is composed of 73 students involved in the preparation and delivery of menu dishes, while the demand side consists of 222 guests of the training restaurant. Both groups' level of agreement was similar when they identified gaps regarding the restaurant's performance in terms of décor, design, lighting and background music. The groups, however, differed in their perceptions of other elements, most notably regarding the selection of beverages, and the entertainment aspect of the dining experience (e.g., deboning fish in front of guests), with students clearly in lesser agreement. Overall, the study's findings demonstrate that involving different groups of stakeholders to evaluate the restaurant's performance could potentially enhance the dining experience.
    • The value of art therapy in antenatal and postnatal care: A brief literature review with recommendations for future research

      Hogan, Susan; Sheffield, David; Woodward, Amelia; University of Derby (Taylor & Francis, 2017-09-01)
      There is a very small body of literature addressing the use of the arts or art therapy in antenatal and post-natal care, and much of it is qualitative, including some rich and complex data which is worthy of discussion and consideration. Overall, it points to a promising use of supportive and therapeutic arts in this area. This article presents some background on the use of the arts specifically focusing on post-natal depression and birth trauma. It then moves on to present a brief survey of literature in the field, followed by some further reflections and discussion about further research needed to establish clinical utility and economic viability.

    • Values production through social and emotional learning

      Wood, Peter; University of Derby (Routledge, 2015)
      This chapter considers if social and emotional learning(SEL) schemes have the potential to marginalise and promote certain values, norms and behaviours, to guard against cultural pollution. It explores the historical underpinnings of values education and highlights concerns regarding values production via the national and hidden curriculum. Education serves a function for society as it should shape social beings by instilling shared moral traditions, practices and ideals. Such opinion is also demonstrable in terminology of various acts of parliament in the United Kingdom, like 1944 Education Act and the Education Reform Act 1988, which both identified the central role of education system in values production. The National Curriculum, which stemmed from latter of these acts, was the first step in explicitly recognising the integral tenet of schooling in shaping the values of pupils, by making it compulsory for schools. Current educational policy and its narrow emphasis on academic performance is one of the obvious barriers to the realisation of mutual reach.

    • Variability in laboratory vs. field testing of peak power, torque, and time of peak power production among elite bicycle motocross cyclists

      Rylands, Lee; Roberts, Simon J.; Hurst, Howard Thomas; University of Derby; Liverpool John Moores University; University of Central Lancashire (Wolters Kluwer, 2015-09)
      The aim of this study was to ascertain the variation in elite male bicycle motocross (BMX) cyclists' peak power, torque, and time of power production during laboratory and field-based testing. Eight elite male BMX riders volunteered for the study, and each rider completed 3 maximal sprints using both a Schoberer Rad Messtechnik (SRM) ergometer in the laboratory and a portable SRM power meter on an Olympic standard indoor BMX track. The results revealed a significantly higher peak power (p ≤ 0.001, 34 ± 9%) and reduced time of power production (p ≤ 0.001, 105 ± 24%) in the field tests when compared with laboratory-derived values. Torque was also reported to be lower in the laboratory tests but not to an accepted level of significance (p = 0.182, 6 ± 8%). These results suggest that field-based testing may be a more effective and accurate measure of a BMX rider's peak power, torque, and time of power production.
