    In the last two decades, several studies have reported on the benefits of Content and Language Integrated Learning (CLIL) on students’ affective and cognitive gains. These studies, however, have mainly concentrated on the implementation of CLIL within the formal (school) context, with very little research on its impact in non-formal (out-of-school) contexts. Thus, the present article addresses this gap by describing an action research project aimed at understanding secondary school students’ attitudes towards the integration of CLIL and museum-based pedagogies. The project involved 284 students (14–16 years old) in northern Italy, who participated in a CLIL museum visit on Animal Classification through English at the Natural History Museum in Venice. A mixed-method research design was implemented and data was collected through students’ questionnaires and focus groups. Results reveal that students showed very positive attitudes towards taking part in a CLIL museum visit based on the interaction among the following dimensions: engagement with museum objects, use of English beyond the classroom, methodology and students’ interests, self-concept and career plans

    Formal reference ranges for rotational thromboelastometry (ROTEM®) in pregnancy have not been obtained in the recommended minimum sample size of 120. This prospective observational study aimed to establish baseline parameters in an Australian population of women undergoing elective caesarean delivery. The secondary aim was to compare these reference ranges with those from prior studies and the manufacturer.Women undergoing elective caesarean delivery at term were included if they were at term, with normal body mass index and had no conditions affecting coagulation. ROTEM® reference ranges were derived by calculating the 2.5 and 97.5 percentiles for INTEM/EXTEM/FIBTEM amplitude at 5 minutes (A5), amplitude at 15 minutes (A15), coagulation time (CT), maximum clot firmness (MCF), and clot formation time (CFT).Of 202 women screened, 132 met the inclusion criteria, having a mean age of 32.7 ± 5.0 years and median body mass index of 23.8 kg/m (interquartile range 21.5-26.4). The reference ranges for selected ROTEM® parameters were as follows: FIBTEM A5 (13-28 mm), FIBTEM CT (40-74 s), FIBTEM MCF (16-34 mm), EXTEM A5 (39-66 mm), EXTEM CT (43-69 s), INTEM A5 (38-63 mm).ROTEM® reference ranges for women with uncomplicated term pregnancies were reported as per the International Federation of Clinical Chemistry. The FIBTEM MCF and FIBTEM/EXTEM/INTEM amplitudes were higher in comparison to the manufacturer's reference ranges for the non-obstetric population. The EXTEM CT was shorter than the non-obstetric reference ranges. These ranges show an increase in coagulability during normal pregnancy compared to the non-pregnant reference ranges

    Infectious Disease Ontology

    Technological developments have resulted in tremendous increases in the volume and diversity of the data and information that must be processed in the course of biomedical and clinical research and practice. Researchers are at the same time under ever greater pressure to share data and to take steps to ensure that data resources are interoperable. The use of ontologies to annotate data has proven successful in supporting these goals and in providing new possibilities for the automated processing of data and information. In this chapter, we describe different types of vocabulary resources and emphasize those features of formal ontologies that make them most useful for computational applications. We describe current uses of ontologies and discuss future goals for ontology-based computing, focusing on its use in the field of infectious diseases. We review the largest and most widely used vocabulary resources relevant to the study of infectious diseases and conclude with a description of the Infectious Disease Ontology (IDO) suite of interoperable ontology modules that together cover the entire infectious disease domain

    Michael Gove’s war on professional historical expertise : conservative curriculum reform, extreme Whig history and the place of imperial heroes in modern multicultural Britain

    Get PDF
    Six years of continuously baiting his opponents within the history profession eventually amounted to little where it mattered most. UK Secretary of State for Education, Michael Gove, finally backtracked in 2013 on his plans to impose a curriculum for English schools based on a linear chronology of the achievements of British national heroes. His ‘history as celebration’ curriculum was designed to instil pride amongst students in a supposedly shared national past, but would merely have accentuated how many students in modern multicultural Britain fail to recognise themselves in what is taught in school history lessons. Now that the dust has settled on Gove’s tenure as Secretary of State, the time is right for retrospective analysis of how his plans for the history curriculum made it quite so far. How did he construct an ‘ideological’ conception of expertise which allowed him to go toe-to-toe for so long with the ‘professional’ expertise of academic historians and history teachers? What does the content of this ideological expertise tell us about the politics of race within Conservative Party curriculum reforms? This article answers these questions to characterise Gove as a ‘whig historian’ of a wilfully extreme nature in his attachment to imperial heroes as the best way to teach national history in modern multicultural Britain

    Effects of membrane depolarization and changes in extracellular [K+] on the Ca2+ transients of fast skeletal muscle fibers. Implications for muscle fatigue

    Repetitive activation of skeletal muscle fibers leads to a reduced transmembrane K+ gradient. The resulting membrane depolarization has been proposed to play a major role in the onset of muscle fatigue. Nevertheless, raising the extracellular K+ (\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}Ko+ {\text{K}}_{\text{o}}^{ + } \end{document}) concentration (\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}[K+]o [ {\text{K}}^{ + } ]_{\text{o}} \end{document}) to 10 mM potentiates twitch force of rested amphibian and mammalian fibers.

Ca2+ transients elicited by single stimulation were potentiated by depolarization from −80 to −60 mV but markedly depressed by further depolarization. Potentiation was inversely correlated with a reduction in the amplitude, overshoot and duration of APs. Similar effects were found for the Ca2+ transients elicited by the first pulse of 100 Hz trains. Depression or block of Ca2+ transient in response to the 2nd to 10th pulses of 100 Hz trains was observed at smaller depolarizations as compared to that seen when using single stimulation. Changes in Ca2+ transients along the trains were associated with impaired or abortive APs.

    Use of information and communication technologies to support effective work practice innovation in the health sector: a multi-site study

    Get PDF
    <p>Abstract</p> <p>Background</p> <p>Widespread adoption of information and communication technologies (ICT) is a key strategy to meet the challenges facing health systems internationally of increasing demands, rising costs, limited resources and workforce shortages. Despite the rapid increase in ICT investment, uptake and acceptance has been slow and the benefits fewer than expected. Absent from the research literature has been a multi-site investigation of how ICT can support and drive innovative work practice. This Australian-based project will assess the factors that allow health service organisations to harness ICT, and the extent to which such systems drive the creation of new sustainable models of service delivery which increase capacity and provide rapid, safe, effective, affordable and sustainable health care.</p> <p>Design</p> <p>A multi-method approach will measure current ICT impact on workforce practices and develop and test new models of ICT use which support innovations in work practice. The research will focus on three large-scale commercial ICT systems being adopted in Australia and other countries: computerised ordering systems, ambulatory electronic medical record systems, and emergency medicine information systems. We will measure and analyse each system's role in supporting five key attributes of work practice innovation: changes in professionals' roles and responsibilities; integration of best practice into routine care; safe care practices; team-based care delivery; and active involvement of consumers in care.</p> <p>Discussion</p> <p>A socio-technical approach to the use of ICT will be adopted to examine and interpret the workforce and organisational complexities of the health sector. The project will also focus on ICT as a potentially <it>disruptive innovation </it>that challenges the way in which health care is delivered and consequently leads some health professionals to view it as a threat to traditional roles and responsibilities and a risk to existing models of care delivery. Such views have stifled debate as well as wider explorations of ICT's potential benefits, yet firm evidence of the effects of role changes on health service outcomes is limited. This project will provide important evidence about the role of ICT in supporting new models of care delivery across multiple healthcare organizations and about the ways in which innovative work practice change is diffused.</p

    Suppressor of cytokine signaling 2 regulates neuronal differentiation by inhibiting growth hormone signaling

    The intracellular mechanisms that determine the response of neural progenitor cells to growth factors and regulate their differentiation into either neurons or astrocytes remain unclear. We found that expression of SOCS2, an intracellular regulator of cytokine signaling, was restricted to mouse progenitor cells and neurons in response to leukemia inhibitory factor (LIF)-like cytokines. Progenitors lacking SOCS2 produced fewer neurons and more astrocytes in vitro, and Socs2(-/-) mice had fewer neurons and neurogenin-1 (Ngn1)-expressing cells in the developing cortex, whereas overexpression of SOCS2 increased neuronal differentiation. We also report that growth hormone inhibited Ngn1 expression and neuronal production, and this action was blocked by SOCS2 overexpression. These findings indicate that SOCS2 promotes neuronal differentiation by blocking growth hormone-mediated downregulation of Ngn1

    The aim of this study was to establish rotational thromboelastometry (ROTEM ) baseline parameters in labouring women at term gestation. The secondary aim was to compare these reference ranges with those from prior studies on labouring women and the manufacturer.A prospective, observational study.Tertiary referral hospital.Healthy women in labour.Ethics approval was granted for an opt-out recruitment approach. ROTEM testing was performed in labouring women at term gestation. Women with any condition affecting coagulation were excluded. ROTEM Delta reference ranges were derived by calculating the 2.5 and 97.5 percentiles for INTEM/EXTEM/FIBTEM parameters including amplitude at 5 minutes (A5), coagulation time (CT) and maximum clot firmness (MCF).ROTEM® parameters were measured in labouring women prior to delivery. The following tests were performed: FIBTEM, EXTEM and INTEM.One hundred and twenty-one women met inclusion criteria, with a mean (SD) age of 29.6 ± 5.4 years and median (interquartile range) gestation of 39.4 weeks (37.4-40.4). Seventy-five (62.0%) women were nulliparous and 71 (58.7%) delivered vaginally. The median and interquartile ranges for selected ROTEM parameters were: FIBTEM A5, 21 millimetres (IQR 18-23); EXTEM A5, 55 millimetres (52-58); and EXTEM CT, 52 seconds (48-56).The FIBTEM/EXTEM/INTEM amplitudes were higher than the manufacturer's reference ranges for non-obstetric patients. The FIBTEM MCF upper and lower limits were higher and the EXTEM/INTEM CT was shorter and narrower in range. This study provides reference ranges for ROTEM values in healthy labouring women at term gestation with uncomplicated pregnancies
