Discussing science in the public sphere: a corpus-assisted study of web-based interaction concerning the measles, mumps and rubella (MMR) triple vaccine

This thesis reports a study into aspects of the discourse concerning the measles, mumps and rubella (MMR) triple vaccine. The aim of the thesis is to contribute to knowledge about the ways in which debates about science are enacted in the public sphere. The study uses a corpus-assisted discourse studies (CADS) approach to examine key lexico-grammatical patterns in the JABS corpus, a corpus of texts gathered from the website of the vaccine-critical Justice Awareness and Basic Support (JABS) group. The aim of the study is to discover how participants on the JABS website discussion forum draw on discursive resources to achieve their rhetorical goals. Comparison is made with the typical lexico-grammatical patterns in the NHSvax corpus, a corpus comprising texts from NHS immunization websites. The study finds that, although there are several areas of similarity between the two corpora, the JABS corpus data contains greater evidence of evaluative lexis, a higher frequency of nouns which express evaluations of the status of discursive objects. These resources are used to reformulate and reframe propositions which originate in the medical-scientific domain. Narratives of vaccine damage are also frequently used to express warrants for expertise

Postglacial (after 18 ka) deep-sea sedimentation along the Hikurangi subduction margin (New Zealand): Characterisation, timing and origin of turbidites

International audienceRecent sedimentation along the Hikurangi subduction margin off northeastern New Zealand is investigated using a series of piston cores collected between 2003 and 2008. The active Hikurangi Margin lies along the Pacific-Australia subduction plate boundary and contains a diverse range of geomorphologic settings. Slope basin stratigraphy is thick and complex, resulting from sustained high rates of sedimentation from adjacent muddy rivers throughout the Quaternary. Turbidites deposited since c. 18 ka in the Poverty, Ruatoria and Matakaoa re-entrants are central to this study in that they provide a detailed record of the past climatic conditions and tectonic activity. Here, alternating hemipelagite, turbidite, debrite and tephra layers reflect distinctive depositional modes of marine sedimentation, turbidity current, debris flow and volcanic eruption, respectively. Turbidites dominate the record, ranging in lithofacies from muddy to sandy turbidites, and include some basal-reverse graded turbidites inferred to be derived from hyperpycnal flows. Stacked turbidites are common and indicate multiple gravity-flows over short time periods. The chronology of turbidites is determined by collating an extremely dense set of radiocarbon ages and dated tephra, which facilitate sedimentation rate calculation and identification of the origin of turbidites. Sedimentation rates range from 285 cm/ka during late glacial time (18.5-17 ka) to 15 to 109 cm/ka during postglacial time (17-0 ka). Turbidite deposition is controlled by: (1) the emplacement of slope avalanches reorganising sediment pathways; (2) the postglacial marine transgression leading to a five-fold reduction in sediment supply to the slope due to disconnection of river mouths from the shelf edge, and (3) the Holocene/ Pleistocene boundary climate warming resulting in a drastic decrease in the average turbidite grain-size. Flood-induced turbidites are scarce: nine hyperpycnites are recognised since 18 ka and the youngest is correlated to the largest ENSO-related storm event recorded onland (Lake Tutira). Other turbidites contain a benthic foraminiferal assemblage which is strictly reworked from the upper slope and which relates to large earthquakes over the last c. 7 ka. They yield a shorter return time (270-430 years) than the published coastal records for large earthquakes (c. 670 years), but the offshore record is likely to be more complete. The deep-sea sedimentation along the New Zealand active margin illustrates the complex interaction of tectonic and climate in turbidite generation. Climate warming and glacio-eustatic fluctuations are well recorded at a millennial timescale (18 ka), while tectonic deformation and earthquakes appear predominant in fostering turbidite production at a centennial timescale (270-430 years)

Effekten av akutt sult og emosjonelt stress på vommiljø og kjøttkvalitet i rein

Resultatene er derfor hittil negative når det gjelder vår hypotese om at stress påvirkervommiljøet og dermed kjøttkvaliteten. Det er imidlertid tvilsomt om dyrene som var slaktet i Kautokeino var tilstrekkelig stresset til å gi et klart utslag. Det bør i denne sammenheng fremheves at det ikke ble påvist dårlig lukt eller andre subjektive tegn på dårlig kjøttkvalitet under slaktingen

Transitions into Higher Education

This book will help all academic staff in higher education (HE) develop more informed teaching and better support students as they transition to university. It explores the organisations who advise students pre-university and uncovers the myths and misconceptions held by HE stakeholders. Induction and welcome activities are examined in order to identify best practice, transition problems such as study skills, employment, mental health and identity are covered, and a final chapter focuses on the effects of Covid-19 on transition issues. The Critical Practice in Higher Education series provides a scholarly and practical entry point for academics into key areas of higher education practice. Each book in the series explores an individual topic in depth, providing an overview in relation to current thinking and practice, informed by recent research. The series will be of interest to those engaged in the study of higher education, those involved in leading learning and teaching or working in academic development, and individuals seeking to explore particular topics of professional interest. Through critical engagement, this series aims to promote an expanded notion of being an academic – connecting research, teaching, scholarship, community engagement and leadership – while developing confidence and authority
