    What does engagement look like in a Media Studies classroom?

    In wider discourses about teaching and learning, ā€œengagementā€ has become something of a contested term, with teachers and educationalists often arguing about what being engaged in education actually involves. This contestation is compounded in media education, because the teacher has to deal with multiple conceptions of audience and, as a consequence, multiple meanings of the term engagement. In this essay, these conceptions and meanings are explored using some primary data taken from surveys of students and teachers from A-Level Media Studies classes, who were asked about both their engagement with the texts they taught and studied on the course, and their engagement with the wider critical study of media texts. The analysis of the data shows varying types and levels of engagement, some of which are personal, some educational and some academically critical. The authors seek to categorise these ā€œengagement eventsā€ in different ways and highlight the idea that engagement in the study of media texts is very different to other types of audience engagement

    Long Term Wind-Driven X-Ray Spectral Variability of NGC 1365 with Swift

    We present long-term (months-years) X-ray spectral variability of the Seyfert 1.8 galaxy NGC 1365 as observed by Swift, which provides well sampled observations over a much longer timescale (6 years) and a much larger flux range than is afforded by other observatories. At very low luminosities the spectrum is very soft, becoming rapidly harder as the luminosity increases and then, above a particular luminosity, softening again. At a given flux level, the scatter in hardness ratio is not very large, meaning that the spectral shape is largely determined by the luminosity. The spectra were therefore summed in luminosity bins and fitted with a variety of models. The best fitting model consists of two power laws, one unabsorbed and another, more luminous, which is absorbed. In this model, we find a range of intrinsic 0.5-10.0 keV luminosities of approximately 1.1-3.5 ergs/s, and a very large range of absorbing columns, of approximately 10^22 - 10^24 cm^-2. Interestingly, we find that the absorbing column decreases with increasing luminosity, but that this result is not due to changes in ionisation. We suggest that these observations might be interpreted in terms of a wind model in which the launch radius varies as a function of ionising flux and disc temperature and therefore moves out with increasing accretion rate, i.e. increasing X-ray luminosity. Thus, depending on the inclination angle of the disc relative to the observer, the absorbing column may decrease as the accretion rate goes up. The weaker, unabsorbed, component may be a scattered component from the wind.Comment: 9 pages, 7 figures, accepted for publication in the Monthly Notices of the Royal Astronomical Societ

    Long-Term X-ray Spectral Variability of Seyfert Galaxies with Swift

    Full text link
    We present analysis of the long-term X-ray spectral variability of Seyfert galaxies as observed by Swift, which provides well-sampled observations over a much larger flux range and a much longer timescale than any other X-ray observatory. We examine long-term variability of three AGN: NGC 1365 (see Connolly et al. 2014), Mkn 335 and NGC 5548. At high fluxes, the 0.5-10 keV spectra soften with increasing flux, as seen previously within the 2-10 keV band. However, at very low fluxes the sources also become very soft. We have fitted a number of models to the data and find that both intrinsic luminosity variability and variable absorption are required to explain the observations. In some systems, e.g. NGC 1365, the best explanation is a two-component wind model in which one component represents direct emission absorbed by a disc wind wind, with the absorbing column inversely proportional to the intrinsic luminosity, and the second component represents unabsorbed emission reflected from the wind. In other AGN the situation is more complex.Comment: 6 pages, 5 figues, to appear in "Swift: 10 years of discovery", Proceedings of Scienc

    A Bayesian Approach to Comparing Cosmic Ray Energy Spectra

    Full text link
    A common problem in ultra-high energy cosmic ray physics is the comparison of energy spectra. The question is whether the spectra from two experiments or two regions of the sky agree within their statistical and systematic uncertainties. We develop a method to directly compare energy spectra for ultra-high energy cosmic rays from two different regions of the sky in the same experiment without reliance on agreement with a theoretical model of the energy spectra. The consistency between the two spectra is expressed in terms of a Bayes factor, defined here as the ratio of the likelihood of the two-parent source hypothesis to the likelihood of the one-parent source hypothesis. Unlike other methods, for example chi^2 tests, the Bayes factor allows for the calculation of the posterior odds ratio and correctly accounts for non-Gaussian uncertainties. The latter is particularly important at the highest energies, where the number of events is very small.Comment: 22 pages, 10 figures, accepted for publication in Ap

    Media literacy, curriculum and the rights of the child

    Get PDF
    Engaging with digital media is part of everyday living for the majority of children, yet opportunities to learn about, through and with media are denied many pupils in compulsory schooling. Whilst Media Studies in the UK is internationally reputed to be well established, changes made to the primary and secondary national curriculum in 2014 included removal of existing media study elements. We demonstrate what is lost by these actions in relation to the United Nations Rights of the Child and, in particular, the right of the child to express identity. We demonstrate how media literacy had previously been included in curriculum, enabling opportunities to address childrenā€™s rights, and propose that the absence of media education is part of an overall trend of the non-prioritisation of childrenā€™s rights in England and Northern Ireland. The paper calls for media literacy to be reintroduced into primary and secondary curriculum

    Who are Non-Resident Fathers?: A British Socio-Demographic Profile

    Despite international growth of, and policy interest in, divorce and separation since the 1970s, there is still surprisingly little known about non-residential fatherhood. This paper presents a 'father-centric' analysis and provides one of the first profiles of non-residential fatherhood in early millennium UK. Using data from Understanding Society Wave 1, a nationally representative survey of over 30,000 households in the UK, we found 1,070 men self-identifying as having a non-resident child under 16 years old (https://www.understandingsociety.ac.uk). We estimate a prevalence of 5 per cent of British men having a non-resident dependent child. Through latent class analysis, four distinct groups of non-resident fathers are identified: 'Engaged' fathers, 'Less Engaged' fathers, 'Disengaged' fathers and 'Distance' fathers. Our analysis finds that non-resident fathers form a heterogeneous group in terms of their socio-demographic profile and family behaviour. It is recommended that legislation and policy concerning fathers in post-separation families are sensitive to variation as well as commonality in socio-economic conditions and family lives and situations

    Britain's slow movement to a Gender Egalitarian Equilibrium: Parents and Employment in the UK 2001 - 2013

    This paper examines the working lives of British couple families across the first decade of the millennium using EU Labour Force Survey data (2001-2013) taking a multiple equilibria approach (Esping-Andersen and Billari, 2015). We identify a growth in dual full-time earners, increased working hours of mothers in part-time employment and a growing proportion of households with ā€˜non-standardā€™ working patterns, suggesting both a convergence and greater diversity in economic provisioning within parent couple households. We find that household employment patterns remain strongly associated with maternal education and family size but are becoming less sensitive to the age of youngest child. The dual full-time earner model is growing in significance for British parents of young children but a new gender egalitarian equilibrium has not yet been reached
