    The liver in amoebic disease

    Get PDF
    During the past 8 years, 305 cases of amoebic disease have been examined at the Department of Diagnostic Radio-isotopes of the H. F. Verwoerd Hospital, Pretoria. Analysis of the data obtained by means of scintigraphy in 247 of these patients indicates that in vivo scintigraphy of the liver is a valuable method for the investigation of many aspects of the disease. Our observations on the localisation of the abscesses, the relationship between localisation and the frequency of complications, the macroscopical changes in the liver during the disease, the presence of a generalised reaction of the liver parenchyma to amoebae in some cases, and the healing rate of abscesses under different types of treatment, are reported in this article.S.

    Chinese labour in the global economy: an introduction

    Get PDF
    This Introduction outlines the main purpose of this special issue volume: to analyse new forms of resistance by Chinese workers against conditions of super-exploitation. After an assessment of the new international division of labour, we provide an overview of Chinese production in the global economy, followed by an introduction of the contributions to this volume

    Limits on axion and light Higgs boson production in Y(1S) decays

    Get PDF
    We have searched for axion and light Higgs boson production in the channel Y(1S) → (a0 or h0)+gamma, where the non-interacting axion a0 and the Higgs boson h0 do not decay in the detector. We find no evidence for an axion and give an upper limit, Br(Y(1S) -> a0 gamma) <4.0x10(-5) (90% CL), for long-lived axions. Combining our limit with the previous search in J/Psi decays, we are able to rule out the axion in the standard model with first order QCD corrections. Our Y(1S) data also rule out a Higgs boson with mass m<86 MeV

    Acute life-threatening extrinsic allergic alveolitis in a paint controller

    Background Occupational diisocyanate-induced extrinsic allergic alveolitis (EAA) is a rare and probably underestimated diagnosis. Two acute occupational EAA cases have been described in this context, but neither of them concerned hexamethylene diisocyanate (HDI) exposure. Aims To investigate the cause of a life-threatening EAA arising at work in a healthy 30-year-old female paint quality controller. Methods Occupational medical assessment, workplace evaluation, airborne and biological monitoring and immunodermatological tests. Results Diagnosis of EAA relied on congruent clinical and radiological information, confirmed occupational HDI exposure and positive IgG antibodies and patch tests. The patient worked in a small laboratory for 7 years, only occasionally using HDI-containing hardeners. While working with HDI for 6 h, she developed breathlessness, rapidly progressing to severe respiratory failure. Workplace HDI airborne exposure values ranged from undetectable levels to 4.25 p.p.b. Biological monitoring of urinary hexamethylene diamine in co-workers ranged from <1.0 to 15.4 μg/g creatinine. Patch tests 8 months later showed delayed skin reaction to HDI at 48 h. Subsequent skin biopsy showed spongiotic dermatitis with infiltration of CD4+ and CD8+ T cells. Conclusions We believe this is the first reported case of acute life-threatening EAA following exposure to HDI. Low concentrations of airborne HDI and relatively high urinary hexamethylene diamine suggest significant skin absorption of HDI could have significantly contributed to the development of this acute occupational EA

    Commodification and ‘the commons’: the politics of privatising public water in Greece and Portugal during the Eurozone Crisis

    Get PDF
    In response to the Eurozone crisis, austerity and restructuring has been imposed on the European Union’s (EU) peripheral member states in order to receive financial bailout loans. In addition to cuts in funding of essential public services, cuts in public sector employment and further liberalisation of labour markets, this has also included pressure towards the privatisation of state assets. And yet, workers have not simply accepted these restructuring pressures. They have organised and fought back against austerity and enforced privatisation. Based on a historical materialist perspective and following a strategy of incorporated comparison, in this paper we will comparatively assess the struggles against enforced water privatisation in Greece and Portugal set against the background of the structuring conditions surrounding the Eurozone crisis

    Distributing Reflexivity through Co-laborative Ethnography

    Get PDF
    In ethnographic research and analysis, reflexivity is vital to achieving constant coordination between field and concept work. However, it has been conceptualized predominantly as an ethnographer’s individual mental capacity. In this article, we draw on ten years of experience in conducting research together with partners from social psychiatry and mental health care across different research projects. We unfold three modes of achieving reflexivity co-laboratively: contrasting and discussing disciplinary concepts in interdisciplinary working groups and feedback workshops; joint data interpretation and writing; and participating in political agenda setting. Engaging these modes reveals reflexivity as a distributed process able to strengthen the ethnographer’s interpretative authority, and also able to constantly push the conceptual boundaries of the participating disciplines and professions.Heinrich Böll Stiftung https://doi.org/10.13039/100009379Deutsche Forschungsgemeinschaft https://doi.org/10.13039/501100001659Deutsche Forschungsgemeinschaft https://doi.org/10.13039/501100001659Peer Reviewe

    Virtual Reality as a Vehicle to Empower Motor-Cognitive Neurorehabilitation.

    Get PDF
    In this paper, we advocate the combination of four key ingredients that we believe are necessary to design long-lasting effective treatments for neurorehabilitation: (i) motor-cognitive training, (ii) evidence-based neuroscience principles, in particular those related to body perception, (iii) motivational games, and (iv) empowerment techniques. Then, we propose virtual reality (VR) as the appropriate medium to encompass all the requirements mentioned above. VR is arguably one of the most suitable technologies for neurorehabilitation able to integrate evidence-based neurorehabilitation techniques and neuroscience principles into motivating training approaches that promote self-management by empowering patients to own their recovery process. We discuss the advantages and challenges of such an approach on several exemplary applications and outline directions for future developments. We strongly believe that the combination of positive psychology and positive technology mediated by VR-based interventions can heavily impact the rehabilitation outcomes of motor-cognitive functions along all the stages of the rehabilitation path
