Developing a coding scheme for analysing classroom dialogue across educational contexts

The research reported sought to develop a framework for systematically analysing classroom dialogue for application across a range of educational settings. The paper outlines the development and refinement of a coding scheme that attempts to represent and operationalise commonalities amongst some key theorists in the field concerning productive forms of educational dialogue. The team has tested it using video recordings from classroom settings in the UK and Mexico, across age phases, subject areas, and different interactional contexts including whole class, group and paired work. Our Scheme for Educational Dialogue Analysis (SEDA) is situated within a sociocultural paradigm, and draws on Hymes' Ethnography of Communication to highlight the importance of context. We examined how such a tool could be used in practice. We found that concentrating on the ‘communicative act’ to explore dialogue between participants was an appropriate level of granularity, while clustering the 33 resulting codes according to function of the acts helped to highlight dialogic sequences within lessons. We report on the application of the scheme in two different learning contexts and reflect on its fitness for purpose, including perceived limitations. Development of specialised sub-schemes and a version for teachers is underway

Overview of the TCV tokamak experimental programme

The tokamak a configuration variable (TCV) continues to leverage its unique shaping capabilities, flexible heating systems and modern control system to address critical issues in preparation for ITER and a fusion power plant. For the 2019-20 campaign its configurational flexibility has been enhanced with the installation of removable divertor gas baffles, its diagnostic capabilities with an extensive set of upgrades and its heating systems with new dual frequency gyrotrons. The gas baffles reduce coupling between the divertor and the main chamber and allow for detailed investigations on the role of fuelling in general and, together with upgraded boundary diagnostics, test divertor and edge models in particular. The increased heating capabilities broaden the operational regime to include T (e)/T (i) similar to 1 and have stimulated refocussing studies from L-mode to H-mode across a range of research topics. ITER baseline parameters were reached in type-I ELMy H-modes and alternative regimes with \u27small\u27 (or no) ELMs explored. Most prominently, negative triangularity was investigated in detail and confirmed as an attractive scenario with H-mode level core confinement but an L-mode edge. Emphasis was also placed on control, where an increased number of observers, actuators and control solutions became available and are now integrated into a generic control framework as will be needed in future devices. The quantity and quality of results of the 2019-20 TCV campaign are a testament to its successful integration within the European research effort alongside a vibrant domestic programme and international collaborations

Effect of different hydrothermal vent conditions in the proteome of vent mussel Bathymodiolus azoricus

The mytilid mussel Bathymodiolus azoricus is the most representative species of north Mid Atlantic Ridge (MAR) hydrothermal vents and is abundantly found at Menez-Gwen, Lucky Strike and Rainbow vent sites.info:eu-repo/semantics/publishedVersio

iTRAQ and DIGE in the ecophysiological characterization of zebra mussel populations (Dreissena polymorpha) invading the Ebro and the Júcar hydrographic basins

Poster presentado en el 9th Iberian and 6th Iberoamerican Congress on Environmental Contamination and Toxicology "The environmental research: essential for sustainability" celebrado en Valencia del 1 al 3 de julio de 2013The invasion of zebra mussel in the ecosystems involves a serious environmental risk, at both ecological and socioeconomic levels. The control of the zebra mussel invasion requires previous knowledge about the main colonization strategies and dispersal ability, as well as a comprehensive study of the mechanisms involved in coping with environmental factors. The study included six populations sampled at diverse locations from the Ebro and Ju¿car basins, differing in their water quality. We have used osmoregulatory and ionoregulatory characters, defences against metal toxicity, and a general health status index for the ecophysiological characterization of zebra mussel populations. Furthermore, proteomics (DIGE and iTRAQ methodology) allowed us to find some of the proteins involved in the physiological adaptation of Dreissena polymorpha to the environmental conditions of the studied sites.Peer Reviewe
