Analysis of cell performance and thermal regeneration of a lithium-tin cell having an immobilized fused-salt electrolyte
Cell performance and thermal regeneration of a thermally regenerative cell uses lithium and tin and a fused-salt electrolyte. The emf of the Li-Sn cell, as a function of cathode-alloy composition, is shown to resemble that of the Na-Bi cell
Adolf Reinach: An Intellectual Biography
The essay provides an account of the development of Reinachās philosophy of āSachverhalteā (states of affairs) and on problems in the philosophy of law, leading up to his discovery of the theory of speech acts in 1913. Reinachās relations to Edmund Husserl and to the Munich phenomenologists are also dealt with
Review of economic evidence in the prevention and early detection of colorectal cancer.
This paper aims to systematically review the cost-effectiveness evidence, and to provide a critical appraisal of the methods used in the model-based economic evaluation of CRC screening and subsequent surveillance. A search strategy was developed to capture relevant evidence published 1999-November 2012. Databases searched were MEDLINE, EMBASE, National Health Service Economic Evaluation (NHS EED), EconLit, and HTA. Full economic evaluations that considered costs and health outcomes of relevant intervention were included. Sixty-eight studies which used either cohort simulation or individual-level simulation were included. Follow-up strategies were mostly embedded in the screening model. Approximately 195 comparisons were made across different modalities; however, strategies modelled were often simplified due to insufficient evidence and comparators chosen insufficiently reflected current practice/recommendations. Studies used up-to-date evidence on the diagnostic test performance combined with outdated information on CRC treatments. Quality of life relating to follow-up surveillance is rare. Quality of life relating to CRC disease states was largely taken from a single study. Some studies omitted to say how identified adenomas or CRC were managed. Besides deterministic sensitivity analysis, probabilistic sensitivity analysis (PSA) was undertaken in some studies, but the distributions used for PSA were rarely reported or justified. The cost-effectiveness of follow-up strategies among people with confirmed adenomas are warranted in aiding evidence-informed decision making in response to the rapidly evolving technologies and rising expectations
Childrenās travel as pedestrians: an international survey of policy and practice
A survey of OECD member countries was carried out to provide high level data on a consistent basis to identify and account for current patterns of child road safety . This paper reports the findings relating to children, aged 0-14 years, as pedestrians. Key survey elements included analyses of fatality data, relationships between socio-economic, demographic factors and fatality rates, and a questionnaire based survey.
League tables based on average child pedestrian fatality rates were constructed for each OECD member country participating in our questionnaire enabling identification of the top five countries with the lowest pedestrian fatality rate as Sweden, The Netherlands, Finland, Germany, and Denmark.
Few countries had quantitative information about childrenās travel and its absence means that assessments are difficult about childrenās safety and the relative risks they face, especially as pedestrians. There are large variations in the amount of walking between countries and growing car use is becoming an issue in one third of OECD countries.
The main findings from the questionnaire survey were that the majority of countries did not have information on high risk groups but of those that did, the cross cutting themes of socio-economic and ethnic minority groups, young children and urban areas were identified.
Three characteristics distinguish top countries in the League table from those doing less well: a strong approach to the introduction of infrastructure measures for pedestrian safety, including low speed limits in residential areas; conducting road safety campaigns at least once a year; and having legislation which assumes driver responsibility in an accident involving a child pedestrian.
Having compulsory road safety education for children aged 6-9 years was a characteristic shared by most countries, as was the promotion of child pedestrian education and training initiatives and the commissioning of research. However there is lower research activity in less well performing countries
Analysis of secondary cells with lithium anodes and immobilized fused-salt electrolytes
Secondary cells with liquid lithium anodes, liquid bismuth or tellurium cathodes, and fused lithium halide electrolytes immobilized as rigid pastes operate between 380 and 485 degrees. Applications include power sources in space, military vehicle propulsion and special commercial vehicle propulsion
Social Justice, The Common Weal and Children and Young People in Scotland
This paper argues that: ā¢ Scotland should organise itself around social justice, which addresses entitlements, redistribution, recognition and respect. ā¢ Children and young people have particular views on what social justice means for them. ā¢ Rights have a particular contribution to make to social justice in term of entitlements, claims and minimal standards. ā¢ The combination of piecemeal incorporation of childrenās rights, an apolitical wellbeing framework and a lack of strong legislation to hold local authorities and other public services, private sector organisations and the third sector to account, results in children and young people encountering discrimination on an everyday basis. ā¢ To achieve social justice, a change is needed in how adults perceive children and childhood, young people and youth. Children and young people need to be recognised as contributors to their families, institutions and communities now ā and not just in the future. ā¢ For children and young people to be included in the Common Weal, it needs to be concerned with the full and diverse range of structural, cultural and individual barriers that they encounter in their lives
Area-level socioeconomic disadvantage and suicidal behaviour in Europe: a systematic review
The relationship between adverse individual socio-economic circumstances and suicidal behaviour is well established. However, the impact of adverse collective circumstances - such as the socio-economic context where people live - is less well understood.
This systematic review explores the extent to which area-level socioeconomic disadvantage is associated with inequalities in suicidal behaviour and self-harm in Europe. We performed a systematic review (in MEDLINE, Embase, PsycINFO, EconLit and Social Sciences Citation Index) from 2005 to 2015. Observational studies were included if they were based in Europe and had a primary suicidal behaviour and self-harm outcome, compared at least two areas, included an area-level measure of socio-economic disadvantage and were published in the English language.
The review followed The Joanna Briggs Institute guidelines for quality appraisal. We identified 27 studies (30 papers) from 14 different European countries. There was a significant association (in 25/27 studies, all of which were rated as of medium or high quality) between socioeconomic disadvantage and suicidal behaviour (and self-harm), particularly for men, and this was a consistent finding across a variety of European countries. Socio-economic disadvantage was found to have an independent effect in several studies whilst others found evidence of mediating contextual and compositional factors. There is strong evidence of an association between suicidal behaviours (and self-harm) and area-level socio-economic disadvantage in Europe, particularly for men. Suicide prevention strategies should take this into account.
Improving the usability of the hierarchical file system
Whether you are interested in improving the usability of Linux, Macintosh or Windows, there is one restriction you cannot escape - the hierarchical file storage system. The notion of files and folders has been with us for so long that it almost seems axiomatic. In this paper we look at the effects on users of forcing a hierarchical classification of files. We also consider how some of the resultant problems can be tackled with a new piece of file browsing software based on the ideas of relational database systems
