    Search for lepton flavor violating decays of a heavy neutral particle in p-pbar collisions at root(s)=1.8 TeV

    Get PDF
    We report on a search for a high mass, narrow width particle that decays directly to e+mu, e+tau, or mu+tau. We use approximately 110 pb^-1 of data collected with the Collider Detector at Fermilab from 1992 to 1995. No evidence of lepton flavor violating decays is found. Limits are set on the production and decay of sneutrinos with R-parity violating interactions.Comment: Figure 2 fixed. Reference 4 fixed. Minor changes to tex

    From evidence-base to practice: implementation of the Nurse Family Partnership programme in England

    Get PDF
    The aims of this article are to highlight the issues that are relevant to the implementation of a rigorously evidence-based programme of support, the Nurse Family Partnership programme, into a national system of care. Methods used are semi-structured interviews with families in receipt of the programme in the first 10 sites, with the nursing staff, with members of the central team guiding the initiative and with other professionals. Analyses of data collected during programme delivery evaluate fidelity of delivery. The results indicate that the programme is perceived in a positive light and take-up is high, with delivery close to the stated US objectives. Issues pertaining to sustainability are highlighted - in particular, local concerns about cost set against long-term rather than immediate gains. However, local investment is predominantly strong, with creative methods being planned for the future. Overall, the study shows that within an NHS system of care it is possible to deliver a targeted evidence-based programme

    ?? Special Feature THE DOSE-RATE EFFECT REVISITED: RADIOBIOLOGICAL CONSIDERATIONS OF IMPORTANCE IN RADIOTHERAPY

    Get PDF
    A wide range of dose-rates have been used in radiation biology and radiation therapy, extending from a few cGy per day to hundreds of Gy in a fraction of a second. The dose-rate range of importance in radiotherapy extends from about 0.1 Gy/br to several Gy/min. In tbis range, the fraction of cells billed by a given dose decreases as tbe dose-rate is reduced, principally because of the repair of sub-lethal damage. In some ceil lines, an inverse dose-rate effect is observed where, over a narrow range of dose-rates, the effectiveness of a given dose increases with decreasing dose-rate if cells move through tbe cycle and are arrested in G,, which is a radiosensitive phase. In recent years data have accumulated for cells of human origin. About 40 data sets have been analyzed for values of tbe survival curve parameters and the rate of repair of sub-lethal damage. These data have been used to address three questions of relevance to radiotherapy

    Exploring the use of new school buildings through post-occupancy evaluation and participatory action research

    Get PDF
    This paper presents the results of the development and testing of an integrated post-occupancy evaluation (POE) approach for teachers, staff, pupils and community members using newly constructed school buildings. It focusses on three cases of UK secondary schools, demonstrating how users can be inspired to engage with the problems of school design and energy use awareness. The cases provided new insights into the engagement of school teachers, staff and young people regarding issues of sustainability, management, functional performance and comfort. The integrative approach adopted in these cases provided a more holistic understanding of these buildings’ performance than could have been achieved by either observational or more traditional questionnaire-based methods. Moreover, the whole-school approach, involving children in POE, provided researchers with highly contextualised information about how a school is used, how to improve the quality of school experiences (both socially and educationally) and how the school community is contributing to the building's energy performance. These POE methods also provided unique opportunities for children to examine the social and cultural factors impeding the adoption of energy-conscious and sustainable behaviours

    Strategies for improving mental health and wellbeing used by older people living with HIV: A qualitative investigation

    Get PDF
    Recent research into “successful ageing” and “resilience” in the context of ageing with HIV highlights older people living with HIV’s (OPLWH) adaptations and coping strategies hitherto neglected by early research’s emphasis on difficulties and challenges. Yet “resilience” and “successful ageing” are limited by their inconsistent definition, conflation of personal traits and coping strategies, normative dimension, and inattention to cultural variation and the distinctive nature of older age. This article thus adopts an interpretivist approach to how OPLWH manage the challenges to their mental health and wellbeing of ageing with HIV. Drawing on interviews with 76 OPLWH (aged 50+) living in the United Kingdom, we document both the strategies these participants use (for example, “accentuating the positive” and accessing external support) and the challenges to these strategies’ success posed by the need to manage their HIV’s social and clinical dimensions and prevent their HIV from dominating their lives. This points to (a) the complex overlaps between challenges to and strategies for improving or maintaining mental health and wellbeing in the context of ageing with HIV, and (b) the limitations of the “resilience” and “successful ageing” approaches to ageing with HIV.

    The contested and contingent outcomes of Thatcherism in the UK

    Get PDF
    The death of Margaret Thatcher in April 2013 sparked a range of discussions and debates about the significance of her period in office and the political project to which she gave her name: Thatcherism. This article argues that Thatcherism is best understood as a symbolically important part of the emergence of first-phase neoliberalism. It engages with contemporary debates about Thatcherism among Marxist commentators and suggests that several apparently divergent positions can help us now reach a more useful analysis of Thatcherism’s short- and long-term outcomes for British political economy. The outcomes identified include: an initial crisis in the neoliberal project in the UK; the transformation of the party political system to be reflective of the politics of neoliberalism, rather than its contestation; long-term attempts at the inculcation of the neoliberal individual; de-industrialisation and financial sector dependence; and a fractured and partially unconscious working class. In all long-term outcomes, the contribution of Thatcherism is best understood as partial and largely negative, in that it cleared the way for a longer-term and more constructive attempt to embed neoliberal political economy. The paper concludes by suggesting that this analysis can inform current debates on the left of British politics about how to oppose and challenge the imposition of neoliberal discipline today

    The poverty of journal publishing

    Get PDF
    The article opens with a critical analysis of the dominant business model of for-profit, academic publishing, arguing that the extraordinarily high profits of the big publishers are dependent upon a double appropriation that exploits both academic labour and universities’ financial resources. Against this model, we outline four possible responses: the further development of open access repositories, a fair trade model of publishing regulation, a renaissance of the university presses, and, finally, a move away from private, for-profit publishing companies toward autonomous journal publishing by editorial boards and academic associations. </jats:p

    Energy transitions and uncertainty: creating low carbon investment opportunities in the UK electricity sector

    Get PDF
    This paper examines how actors in the UK electricity sector are attempting to deliver investment in low carbon generation. Low carbon technologies, because of their relative immaturity, capital intensity and low operational costs, do not readily fit with existing electricity markets and investment templates which were designed for fossil fuel based energy. We analyse key electricity market and infrastructure policies in the UK and highlight how these are aimed at making low carbon technologies ‘investable’ by reducing uncertainty, managing investment risks and repositioning actors within the electricity socio-technical ‘regime’. We argue that our study can inform contemporary debates on the politics and governance of sustainability transitions by empirically investigating the agency of incumbent regime actors in the face of uncertainty and by offering critical insights on the role of markets and finance in shaping socio-technical change

    Developing Dementia-Friendly Tourism Destinations: An Exploratory Analysis

    Get PDF
    Dementia is emerging as a global issue. Increases in life expectancy create an older population structure with accompanying health needs but also high lifestyle expectations. For example existing generations have come to expect to be able to participate in leisure and tourism activities in later life, which can be constrained by the onset of dementia. Leading healthy lifestyles and engaging in tourism activities are viewed as fundamental to remaining active and contributing to slowing the progress of dementia. This study is the first to examine the challenges and implications of the growing scale of dementia and the business opportunities this may create for destinations wishing to achieve dementia-friendly status. The paper reports results from an initial scoping study with tourism businesses in a coastal resort in the United Kingdom with such ambitions to assess the nature of the issues that arose from a series of face-to-face interviews
