    Fibre supercapacitors were designed and manufactured using a dip-coating method. Their electrochemical properties were characterized using a VersaSTAT 3 workstation. Chinese ink with a fine dispersion of carbon and binder was coated as the electrode material. The specific capacitance per unit length of a copper fibre supercapacitor with the length of 41 cm reached 34.5 mF/cm. When this fibre supercapacitor was bent on rods with a diameter of 10.5 cm, the specific capacitance per length was 93% of the original value (without bending). It showed that these fibre supercapacitors have good flexibility and energy storage capacity. Furthermore, the fibre supercapacitor in the fabric showed the same capacitance before and after weaving.The European Union Seventh Framework Programme (FP7/2007–2013) under grant agreement no.

    Building an evidence base for adult safeguarding?: problems with the reliability and validity of adult safeguarding databases

    This article considers current adult safeguarding policy guidelines for England, which require local authorities to collect adult safeguarding data for the purposes of research and service development. It then moves on to report some of the findings from an evaluation of adult safeguarding in one English local authority, focussing on how the adult safeguarding database was populated from case records and how the resultant data was utilised. It found that, although the annual number of adult safeguarding alerts more than tripled between 2002 and 2008, this clear evidence of an increase in workload had not resulted in increased resource allocation. The evaluation further noted that only half of the designated ‘adult safeguarding managers’ who were interviewed were able to correctly define the meanings of the recommended terms under which adult safeguarding outcomes are recorded, i.e. ‘substantiated’, ‘not substantiated’ and ‘not determined’. Changes to the terminology used to record the outcomes of safeguarding investigations are proposed as one of a number of measures to enable the creation of valid and reliable information upon which to base future practice developments, including allocation of resources.

    A study of the electrochemical performance of strip supercapacitors under bending conditions

    © 2016 The Authors. In recent years, much effort has been spent developing thin, lightweight and flexible energy storage devices to meet the various requirements of modern smart electronics. In this work, thin strip supercapacitors were successfully developed using activated carbon as the active electrode material. The electrochemical performance of these strip supercapacitors has been studied under mechanical bending conditions. The results indicate that the strip supercapacitor was functional under bending conditions between the bending angles of 30° to 150°. The capacitance of the sample was still about 70% of the original capacitance at different bending angles. This suggests the strip supercapacitor developed has a reasonable flexibility. Simulation model of equivalent circuit was established to analyze the charge transfer resistance (CTR) and equivalent series resistance (ESR) results in electrochemical impedance spectroscopy (EIS) testing. The correlation between the capacitance and the resistance of the strip supercapacitor under bending conditions was investigated and obtained.The European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement no. 28106

    My Marriage My Choice. Summary of Findings

    Get PDF
    The My Marriage My Choice project (a two-year study funded by the National Institute for Health Research, School for Social Care Research) has been conducted with a view to exploring forced marriage of adults with learning disabilities1 from a safeguarding perspective. Its aim was to develop knowledge, policy and practice to support professionals in their work of safeguarding vulnerable children and adults. Forced marriage is defined as a marriage without the consent of one or both parties and where duress is a factor (UK Government Forced Marriage Unit). In a forced marriage one or both spouses do not consent, or due to lacking capacity, cannot consent to the marriage. The research project has also been conducted to raise awareness of forced marriage in order that all of those who are involved in the education, care and support of individuals who cannot effectively consent to any such undertaking, might be empowered to recognise forced marriage as such and respond appropriately

    My Marriage My Choice. Case Study Collection: Learning from case studies of forced marriage of people with learning disabilities

    Get PDF
    This document tells the stories of people with learning disabilities who have been forced to marry, to raise the profile of a little understood issue and contribute to a shift in thinking that will improve safeguarding policy and practice. Forced marriage of people with learning disabilities is different to forced marriage of people without learning disability. As such, it is often not recognised as forced by families, faith leaders or professionals. Some professionals see it as a ‘cultural issue’ and fear being seen as racist or culturally insensitive. This all impacts upon safeguarding policy and practice

    'I was just gobsmacked': care workers responses to BBC Panoramas 'Undercover care: the abuse exposed': invoking mental states as a means of distancing from abusive practices

    Get PDF
    This paper draws upon discourse analytic techniques and discursive psychology to examine how care workers build accounts of viewing the BBC Panorama programme “Undercover Care: The Abuse Exposed” which graphically documented the abuse of people with learning disabilities in a residential care setting. 56 interviews were conducted as part of a project concerning adult safeguarding. The analysis considers how careworkers report their reactions and the interactional strategies they use to construct themselves as shocked and disbelieving and thus, as oppositional to the extreme practices in the programme. Their role as careworkers, and therefore as ‘insiders’ of the industry that allowed such abuse to happen, makes matters of stake and agency live issues for this particular group; and constructions of ‘shock’ and ‘disbelief’ are potential ways for participants to distance themselves from the abuse shown in the programme. More broadly, these data show how the invocation of mental states contributes to the management of other discursive business, namely, that of fending off any association with the aforementioned extreme practices

    The Structure of the EU Mediasphere

    Background. A trend towards automation of scientific research has recently resulted in what has been termed “data-driven inquiry” in various disciplines, including physics and biology. The automation of many tasks has been identified as a possible future also for the humanities and the social sciences, particularly in those disciplines concerned with the analysis of text, due to the recent availability of millions of books and news articles in digital format. In the social sciences, the analysis of news media is done largely by hand and in a hypothesis-driven fashion: the scholar needs to formulate a very specific assumption about the patterns that might be in the data, and then set out to verify if they are present or not. Methodology/Principal Findings. In this study, we report what we think is the first large scale content-analysis of cross-linguistic text in the social sciences, by using various artificial intelligence techniques. We analyse 1.3 M news articles in 22 languages detecting a clear structure in the choice of stories covered by the various outlets. This is significantly affected by objective national, geographic, economic and cultural relations among outlets and countries, e.g., outlets from countries sharing strong economic ties are more likely to cover the same stories. We also show that the deviation from average content is significantly correlated with membership to the eurozone, as well as with the year of accession to the EU. Conclusions/Significance. While independently making a multitude of small editorial decisions, the leading media of the 27 EU countries, over a period of six months, shaped the contents of the EU mediasphere in a way that reflects its deep geographic, economic and cultural relations. Detecting these subtle signals in a statistically rigorous way would be out of the reach of traditional methods. This analysis demonstrates the power of the available methods for significant automation of media content analysis
