Laterites and paleoclimates. Weathering processes and anthropogenic impact

The European Union of Geosciences held its 9th biannual meeting in Strasbourg, March 23–27, 1997. During this meeting, Symposium No. 63, Weathering Processes: Mineral deposits and soil formation in tropical enÍironments, was merged with Symposium No. 78, Anthropogenic Impact on Weathering processesco-sponsored by IGCP Project 405. The resulting symposium No. 63, Weathering processes and Anthropogenic Impact, was held under the sponsorship of EUROLAT1 and attracted 36 oral and poster presentations and about 100 participants, reflecting the interest of the Earth Sciences community in weathering processes and anthropogenic impact

Collectively Creative: a means to perceive differently

This feature article is a response to the question " Can anyone be creative?"In dialogue with the Editor of the Hong Kong Youth Journal Elaine Morgan the argument is made that it is possible given the right environment. The significance of the creative arts in the establishment of social justice in education is highlighted

Optimisation of maintenance scheduling strategies on the grid

The emerging paradigm of Grid Computing provides a powerful platform for the optimisation of complex computer models, such as those used to simulate real-world logistics and supply chain operations. This paper introduces a Grid-based optimisation framework that provides a powerful tool for the optimisation of such computationally intensive objective functions. This framework is then used in the optimisation of maintenance scheduling strategies for fleets of aero-engines, a computationally intensive problem with a high-degree of stochastic noise, achieving substantial improvements in the execution time of the algorithm

Local and global query expansion for hierarchical complex topics

In this work we study local and global methods for query expansion for multifaceted complex topics. We study word-based and entity-based expansion methods and extend these approaches to complex topics using fine-grained expansion on different elements of the hierarchical query structure. For a source of hierarchical complex topics we use the TREC Complex Answer Retrieval (CAR) benchmark data collection. We find that leveraging the hierarchical topic structure is needed for both local and global expansion methods to be effective. Further, the results demonstrate that entity-based expansion methods show significant gains over word-based models alone, with local feedback providing the largest improvement. The results on the CAR paragraph retrieval task demonstrate that expansion models that incorporate both the hierarchical query structure and entity-based expansion result in a greater than 20% improvement over word-based expansion approaches

Creativity and Democracy in Education: Practices and politics of learning through the arts

Research MonograpghWith particular reference to the practices and politics of learning through the arts this book (Research Monograph) forms part of the Routledge Research in Education Policy and Politics series aims to enhance our understanding of key challenges and facilitate on-going academic debate within the influential and growing field of Education Policy and Politics.Many of the projects discussed in the book have been supported by research councils, businesses, educational societies, learned societies and charities with acknowledged funding from: British Academy; British Council; World Bank; EU Comenius and Grundtvig Schemes; Cheshire West and Chester Council; Race Hate Crime UK; Society for the Advancement of Management Studies; Royal Society of Arts (North West Venture Fund); Japan Foundation, Santander; Higher Education Academy; Higher Education Funding Council; National endowment for Science, Technology and the Arts; Esmée Fairbairn Foundation; Korean Society for Education through Art; National Society for Education in Art and Design; Tate

Understandings of creative practice and pedagogy by teacher education communities in West Bank, Palestine, and North West England

This is an Accepted Manuscript of an article published by Taylor & Francis in Discourse on 27/01/2020, available online: https://www.tandfonline.com/doi/full/10.1080/01596306.2019.1708706.This paper discusses a collaborative research project that aimed to explore approaches to creative practices and pedagogies by teacher education communities in the West Bank, Palestine, and North West England (Bethlehem and Chester). The project explored the values, attitudes and perceptions of teacher educators and student teachers in relation to creative pedagogies and the conditions under which they flourished in each community. We found that creativity was understood to take many forms, according to the cultural values and conditions present in each community, and that creative pedagogical forms emerged from the specificities of their cultural and political contexts. Creativity in education is a contentious issue in both cultures, but an area that both education communities wished to explore further. Despite the differences, there were surprising commonalities between the two communities about the value of creative practices and the relation of creativity to democratic and critical practices in the classroom

Towards understanding the clinical significance of QT peak prolongation: a novel marker of myocardial ischemia independently demonstrated in two prospective studies

Background: QT peak prolongation identified patients at risk of death or non-fatal MI. We tested the hypothesis that QT peak prolongation might be associated with significant myocardial ischaemia in two separate cohorts to see how widely applicable the concept was. Methods and Results: In the first study, 134 stroke survivors were prospectively recruited and had 12-lead ECGs and Nuclear myocardial perfusion scanning. QT peak was measured in lead I of a 12-lead ECG and heart rate corrected by Bazett’s formula (QTpc). QTpc prolongation to 360ms or more was 92% specific at diagnosing severe myocardial ischaemia. This hypothesis-generating study led us to perform a second prospective study in a different cohort of patients who were referred for dobutamine stress echocardiography. 13 of 102 patients had significant myocardial ischaemia. Significant myocardial ischaemia was associated with QT peak prolongation at rest (mean 354ms, 95% CI 341-367ms, compared with mean 332ms, 95% CI 327-337ms in those without significant ischaemia; p=0.002). QT peak prolongation to 360ms or more was 88% specific at diagnosing significant myocardial ischaemia in the stress echocardiography study. QT peak prolongation to 360ms or more was associated with over 4-fold increase odds ratio of significant myocardial ischaemia. The Mantel- Haenszel Common Odds Ratio Estimate=4.4, 95% CI=1.2-16.0, p=0.023. Conclusion: QT peak (QTpc) prolongation to 360ms or more should make us suspect the presence of significant myocardial ischaemia. Such patients merit further investigations for potentially treatable ischaemic heart disease to reduce their risk of subsequent death or non-fatal MI
