'You were quiet - I did all the marching': Research processes involved in hearing the voices of South Asian girls

This article is available open access through the publisher’s website at the link below. Copyright @ 2011 A B Academic Publishers.This article provides insights into the outcomes of reflection following two interview approaches used to explore narratives of the lived, individual experiences of South-Asian girls living in West London. In attempting to illuminate and re-present the cultural experiences as told by these girls, the choice of interview approach became critical in allowing the voices to be effectively heard (Rogers, 2005). This article therefore considers how a semi-structured interview approach offered valuable insights into the girls' experiences but became constraining for both researcher and participant in unveiling the complexity and depth of their lives. These constraints emerged through reflection by both participants and researcher. As a result of reflexivity during the research process, the researcher moved towards the use of research conversations during the second phase of the study. Ultimately the study revealed how the girls felt empowered by the opportunity to narrate their individual experiences and tell of their lives. In narrating their reflections on being part of the research, there was a clear recognition that the process facilitated the articulation of new voices and ‘multi-voicedness’ (Moen, 2006

Two-Photon Fluorescence Microscopy Imaging of Cellular Oxidative Stress Using Profluorescent Nitroxides

A range of varying chromophore nitroxide free radicals and their nonradical methoxyamine analogues were synthesized and their linear photophysical properties examined. The presence of the proximate free radical masks the chromophore’s usual fluorescence emission, and these species are described as profluorescent. Two nitroxides incorporating anthracene and fluorescein chromophores (compounds 7 and 19, respectively) exhibited two-photon absorption (2PA) cross sections of approximately 400 G.M. when excited at wavelengths greater than 800 nm. Both of these profluorescent nitroxides demonstrated low cytotoxicity toward Chinese hamster ovary (CHO) cells. Imaging colocalization experiments with the commercially available CellROX Deep Red oxidative stress monitor demonstrated good cellular uptake of the nitroxide probes. Sensitivity of the nitroxide probes to H2O2-induced damage was also demonstrated by both one- and two-photon fluorescence microscopy. These profluorescent nitroxide probes are potentially powerful tools for imaging oxidative stress in biological systems, and they essentially “light up” in the presence of certain species generated from oxidative stress. The high ratio of the fluorescence quantum yield between the profluorescent nitroxide species and their nonradical adducts provides the sensitivity required for measuring a range of cellular redox environments. Furthermore, their reasonable 2PA cross sections provide for the option of using two-photon fluorescence microscopy, which circumvents commonly encountered disadvantages associated with one-photon imaging such as photobleaching and poor tissue penetration

‘It’s never okay to say no to teachers’: children’s research consent and dissent in conforming schools contexts

This article examines the limits to children giving research consent in everyday school contexts that emphasises their conformity to comply with adult expectations, and highlights children’s competence and agency in navigating this conformity through different practices of dissent. It draws on research into children’s agency, using a multimodal ethnography of Year 1 classrooms in two English primary schools. The article includes a reflexive methodological focus, exploring the extent to which I counter the schools’ emphasis on conformity. This includes creating visuals for children to practice consent; positioning myself as the researcher in a non‐teacher role, as ‘least adult’ and the one who ‘least knows’; and designing interview spaces markedly different from classrooms. The article examines how children navigate conforming discourses by finding different ways to dissent in the research. Firstly, children demonstrate a sophisticated awareness of the cultural norms of indicating refusals beyond saying the word ‘No’. Secondly, children achieve unnoticeablity, by which they absent themselves from the ‘on‐task’ classroom culture, and by extension the research process. Thirdly, they engage in playful dissent, demonstrating their political knowingness of the classroom social order. The article discusses the implications for educational research when the values of consent are in conflict with a schooling focused on conformity. This includes emphasising the limits of consent procedures, paying closer attention to how researchers recognise and respond ethically to children’s multiple practices of dissent, and using research to disrupt problematic power structures in education settings that limit possibilities for children’s consent

Reproduction and transformation of inequalities in schooling: The transformative potential of the theoretical constructs of Bourdieu

This article is concerned with the theoretical constructs of Bourdieu and their contribution to understanding the reproduction of social and cultural inequalities in schooling. While Bourdieu has been criticised for his reproductive emphasis, this article proposes that there is transformative potential in his theoretical constructs and that these suggest possibilities for schools and teachers to improve the educational outcomes of marginalised students. The article draws together three areas of contribution to this theme of transformation; beginning by characterising habitus as constituted by reproductive and transformative traits and considering the possibilities for the restructuring of students’ habitus. This is followed by a discussion of cultural capital and the way that teachers can draw upon a variety of cultural capitals to act as agents of transformation rather than reproduction. The article concludes by considering the necessity of a transformation of the field to improve the educational outcomes of marginalised students

Epidemiological and cohort study finds no association between COVID-19 and Guillain-Barré syndrome

Reports of Guillain-Barré syndrome (GBS) have emerged during the Coronavirus disease 2019 (COVID-19) pandemic. This epidemiological and cohort study sought to investigate any causative association between COVID-19 infection and GBS. The epidemiology of GBS cases reported to the UK National Immunoglobulin Database was studied from 2016 to 2019 and compared to cases reported during the COVID-19 pandemic. Data were stratified by hospital trust and region, with numbers of reported cases per month. UK population data for COVID-19 infection were collated from UK public health bodies. In parallel, but separately, members of the British Peripheral Nerve Society prospectively reported incident cases of GBS during the pandemic at their hospitals to a central register. The clinical features, investigation findings and outcomes of COVID-19 (definite or probable) and non-COVID-19 associated GBS cases in this cohort were compared. The incidence of GBS treated in UK hospitals from 2016 to 2019 was 1.65–1.88 per 100 000 individuals per year. GBS incidence fell between March and May 2020 compared to the same months of 2016–19. GBS and COVID-19 incidences during the pandemic also varied between regions and did not correlate with one another (r = 0.06, 95% confidence interval: −0.56 to 0.63, P = 0.86). In the independent cohort study, 47 GBS cases were reported (COVID-19 status: 13 definite, 12 probable, 22 non-COVID-19). There were no significant differences in the pattern of weakness, time to nadir, neurophysiology, CSF findings or outcome between these groups. Intubation was more frequent in the COVID-19 affected cohort (7/13, 54% versus 5/22, 23% in COVID-19-negative) attributed to COVID-19 pulmonary involvement. Although it is not possible to entirely rule out the possibility of a link, this study finds no epidemiological or phenotypic clues of SARS-CoV-2 being causative of GBS. GBS incidence has fallen during the pandemic, which may be the influence of lockdown measures reducing transmission of GBS inducing pathogens such as Campylobacter jejuni and respiratory viruses

Mediated Class-ifications: Representations of Class and Culture in Contemporary British Television

This article takes, as its point of departure, recent debates about the representation of working-class life, especially the lives of the 'feckless poor', on reality television in the UK. These issues are contextualized by reference to a set of wider-ranging historical debates about: a) the category of class as a mode of social determination (and as an explanatory model); b) the relations of language, class and culture in educational sociology and in community publishing; and, c) in relation to classical Marxism's theorization of both the 'respectable' working class and the lumpen proletariat. The article concludes with a consideration of debates about the representation of the working class in the contemporary British TV drama series Shameless
