      Xu, Xiao; Hu, Weihao; Cao, Di; Liu, Wen; Huang, Qi; Hu, Yanting; Chen, Zhe
      Extensive studies have been carried out on various hybrid energy systems (HESs) for providing electricity to off-grid areas. However, a standalone HES that is capable of providing power and gas, has been less studied. In this paper, a standalone Photovoltaic (PV)-battery-methanation HES is proposed to provide adequate, reliable and cost-effective electricity and gas to the local consumers. Identifying a potential solution to maximize the reliability of the system, asked by consumers, and to minimize costs required by the investors is challenging. Bi-level programming is adopted in this study to tackle the pre-mentioned issue. In the outer layer, an optimal design is obtained by means of particle swarm optimization. In the inner layer, an optimal operation strategy is found under the optimal design of the outer layer using sequential quadratic programming. The results indicate that 1) The bi-level programming used in this study can find the optimal solution; 2) The proposed HES is proved to be able to supply power and gas simultaneously. 3) Compared with the right most and leftmost points on Pareto set, the total costs are reduced by 17.77% and 2.16%.

    • Population Health Screening after Environmental Pollution

      Stewart, Alex G.; orcid: 0000-0002-4931-5340; email: dragonsteeth@doctors.org.uk; Wilkinson, Ewan; orcid: 0000-0002-2167-8756; email: ewilkinson@chester.ac.uk (MDPI, 2020-11-24)
      Following environmental pollution exposure, calls to screen the population for disease or disease markers are often made. Population screening is a cross-sectional review of a population to find latent cases or biomarkers of disease that indicate the possibility of disease development; it differs from environmental screening or an epidemiological survey. Recognized standard approaches have been developed over 60 years to ensure quality and effectiveness in complex programs. We surveyed the literature for papers on health screening following environmental exposures and checked them for reference to accepted criteria such as those of Wilson and Jungner. We applied these criteria to three situations covering source/hazard (arsenic contaminated land), pathway/exposure (radiation release), and receptor/disease (lead poisoning). We identified 36 relevant papers. Although across the papers the whole range of criteria were addressed, no paper or program utilized recognized criteria. Issues and gaps identified included limited strategic approaches, lack of treatment, environmental prevention being seen as the screening outcome instead of treatment of identified individuals, and programs which did not fit the World Health Organization screening description. Robust discussion in the literature is needed to consider the organization and role of health screening following environmental exposures.
    • The role of antibody expression and their association with bladder cancer recurrence: a single-centre prospective clinical-pilot study in 35 patients

      Ella-tongwiis, Peter; Lamb, Rebecca May; Makanga, Alexander; Shergill, Iqbal; Hughes, Stephen Fôn; orcid: 0000-0001-6558-9037; email: Stephen.hughes6@wales.nhs.uk (BioMed Central, 2020-11-25)
      Abstract: Background: Bladder cancer (BC) is the 10th most common cancer in the UK, with about 10,000 new cases annually. About 75–85% of BC are non-muscle invasive (NMIBC), which is associated with high recurrence and progression rates (50–60% within 7–10 years). There are no routine biomarkers currently available for identifying BC patients at increased risk of developing recurrence. The focus of this research study was to evaluate antibody expression in BC patients and their association with cancer recurrence. Methods: 35 patients scheduled for TURBT were recruited after written informed consent. Ethical approval for the project was granted via IRAS (REC4: 14/WA/0033). Following surgical procedure, tissues were preserved in 10% buffered formalin and processed within 24 h in FFPE blocks. 7 sections (4 µm each) were cut from each block and stained for CD31, Human epidermal growth factor receptor-2 (HER-2), S100P, Cyclooxygenase-2 (COX-2), VEGFR-3 thrombomodulin and CEACAM-1 using immunohistochemistry. Clinical outcome measures (obtained via cystoscopy) were monitored for up to 6 months following surgical procedure. Results: There was significantly increased expression of CD31 (p < 0.001), HER-2 (p = 0.032), S100P (p < 0.001), COX-2 (p < 0.001), VEGFR-3 (p < 0.001) and decreased expression of thrombomodulin (p = 0.010) and CEACAM-1 (p < 0.001) in bladder tumours compared to normal bladder tissues. HER-2 expression was also significantly associated with cancer grade (p = 0.003), especially between grade 1 and grade 2 (p = 0.002) and between grade 1 and grade 3 (p = 0.004). There was also a significant association between cancer stage and HER-2 expression (p < 0.001). Although recurrence was significantly associated with cancer grade, there was no association with antibody expression. Conclusion: Findings from the present study may indicate an alternative approach in the monitoring and management of patients with BC. It is proposed that by allowing urological surgeons access to laboratory markers such as HER-2, Thrombomodulin and CD31 (biomarker profile), potentially, in the future, these biomarkers may be used in addition to, or in combination with, currently used scoring systems to predict cancer recurrence. However, verification and validation of these biomarkers are needed using larger cohorts.

    • Concentrated Noir: Reinforcing and transgressing genre boundaries in Echo

      Waller, Rhian (Intellect, 2021-01-01)
      Nordic Noir has emerged as an increasingly codified set of aesthetic, political and philosophical televisual elements. Echo compresses these elements, subjecting them to the crucible of short film. This article investigates the dramatic potential of stripping back cross-genre tropes to reveal the defining characteristics of a newly emergent format.
    • Exploring the emotional experience of lean.

      Taylor, Siobhan; McSherry, Robert; Cook, Susy; Giles, Emma (2020-11-10)
      This research aims to contribute to the literature on Lean implementation in healthcare by studying the emotional experiences of the relevant actors related to a Rapid Process Improvement Workshop (RPIW) in a UK healthcare context. The purpose of this study was to go beyond what people think about Lean and towards an exploration of their subjective, emotional and "feeling" experience and whether that emotional experience influenced Lean implementation. A phenomenological and symbolic interactionist qualitative case study was undertaken. Data related to participants' emotional experience were collected through non-participant observation and semi-structured interviews. Data were analysed using thematic network analysis. This paper provides novel insights into the emotional experience of Lean as experienced through an RPIW. The findings reveal that participation in an RPIW is much more than a technical process. It influences how people feel about themselves, is based on relationships with others, and requires mental, physical and emotional effort. All of these factors influence engagement with, initiation of and sustainability of the RPIW. A new conceptual framework for the planning and implementation of RPIWs has been developed. However, because of the chosen research approach, the results may lack generalisability. Therefore, researchers are encouraged to test the framework and proposed practice implications. Despite emotions being an integral part of individual and social everyday life, emotional experience has not been studied in relation to Lean. This study is the first to explore emotions in relation to Lean, with implications for practice as to how RPIWs are managed with a new framework for implementation being proposed.

    • Deception Detection and Truth Detection Are Dependent on Different Cognitive and Emotional Traits: An Investigation of Emotional Intelligence, Theory of Mind, and Attention

      Stewart, Suzanne L. K.; orcid: 0000-0003-2152-0091; Wright, Clea; Atherton, Catherine (SAGE Publications, 2018-09-28)
      Despite evidence that variation exists between individuals in high-stakes truth and deception detection accuracy rates, little work has investigated what differences in individuals’ cognitive and emotional abilities contribute to this variation. Our study addressed this question by examining the role played by cognitive and affective theory of mind (ToM), emotional intelligence (EI), and various aspects of attention (alerting, orienting, executive control) in explaining variation in accuracy rates among 115 individuals (87 women; mean age = 27.04 years [ SD = 11.32]) who responded to video clips of truth-tellers and liars in real-world, high-stakes contexts. Faster attentional alerting supported truth detection, and better cognitive ToM and perception of emotion (an aspect of EI) supported deception detection. This evidence indicates that truth and deception detection are distinct constructs supported by different abilities. Future research may address whether interventions targeting these cognitive and emotional traits can also contribute to improving detection skill.

    • Celebration of the Centenary of the first female Fellows: Introduction

      Burek, C. V.; orcid: 0000-0002-7931-578X; Higgs, B. M. (Geological Society of London, 2020-11-12)
      AbstractThe Geological Society of London was founded in 1807. At the time, membership was restricted to men, many of whom became well-known names in the history of the geological sciences. On the 21st May 1919 the first female Fellows were elected to the Society, 112 years after its foundation. This Special Publication celebrates the centenary of that important event. It builds on a previous Special Publication of the Geological Society, The Role of Women in the History of Geology (Burek &amp; Higgs, 2007a) which was the first book to deal solely with the role that women played in the history and development of the geological sciences. The research and learning in the 2007 publication followed the first ever conference to be held on the work of early female geologists, held at the Geological Society in 2005.
    • A validated food frequency questionnaire to determine dietary intake of vitamin D.

      Watkins, Stephanie; Freeborn, Ellen; Mushtaq, Sohail (2020-11-06)
      The aim of the present study was to develop and validate a vitamin D food frequency questionnaire (FFQ) for assessment of dietary vitamin D intake in healthy adults in England, UK. The current study assessed the agreement between a four-day food diary (4d-FD) and a new vitamin D FFQ to measure dietary intake of vitamin D. Dietary intake was estimated using Nutritics dietary analysis software and Spearman's and Bland-Altman tests were utilised to assess correlation and agreement, respectively. Participants also provided a blood sample for plasma analysis of vitamin D concentrations. Home setting. Fifty participants were recruited to the study from the University of Chester and vicinity. Results showed a strong correlation between vitamin D intake recorded by the FFQ and the 4d-FD (r = 0.609; P < 0.0001) within 95% limits of agreement. Furthermore, a significant correlation between plasma 25(OH)D concentrations and vitamin D intake measured by the FFQ (r = 0.290, P = 0.041) and the 4d-FD (r = 0.360, P = 0.01) was observed. Our analysis suggests this FFQ is a useful and rapid tool for researchers and health professionals to assess vitamin D dietary intakes in healthy adults in the UK.
