    Moral dilemmas and abortion decision-making: Lessons learnt from abortion research in England and Wales

    This paper scrutinises the concepts of moral reasoning and personal reasoning, problematising the binary model by looking at young women's pregnancy decision-making. Data from two UK empirical studies are subjected to theoretically driven qualitative secondary analysis, and illustrative cases show how complex decision-making is characterised by an intertwining of the personal and the moral, and is thus best understood by drawing on moral relativism

    Multi-population GWA mapping via multi-task regularized regression

    Get PDF
    Motivation: Population heterogeneity through admixing of different founder populations can produce spurious associations in genome- wide association studies that are linked to the population structure rather than the phenotype. Since samples from the same population generally co-evolve, different populations may or may not share the same genetic underpinnings for the seemingly common phenotype. Our goal is to develop a unified framework for detecting causal genetic markers through a joint association analysis of multiple populations

    Fregene: Simulation of realistic sequence-level data in populations and ascertained samples

    Background: FREGENE simulates sequence-level data over large genomic regions in large populations. Because, unlike coalescent simulators, it works forwards through time, it allows complex scenarios of selection, demography, and recombination to be modelled simultaneously. Detailed tracking of sites under selection is implemented in FREGENE and provides the opportunity to test theoretical predictions and gain new insights into mechanisms of selection. We describe here main functionalities of both FREGENE and SAMPLE, a companion program that can replicate association study datasets.Results: We report detailed analyses of six large simulated datasets that we have made publicly available. Three demographic scenarios are modelled: one panmictic, one substructured with migration, and one complex scenario that mimics the principle features of genetic variation in major worldwide human populations. For each scenario there is one neutral simulation, and one with a complex pattern of selection.Conclusion: FREGENE and the simulated datasets will be valuable for assessing the validity of models for selection, demography and population genetic parameters, as well as the efficacy of association studies. Its principle advantages are modelling flexibility and computational efficiency. It is open source and object-oriented. As such, it can be customised and the range of models extended

    Sparrows can't sing : East End kith and kinship in the 1960s

    Sparrows Canā€™t Sing (1963) was the only feature film directed by the late and much lamented Joan Littlewood. Set and filmed in the East End, where she worked for many years, the film deserves more attention than it has hitherto received. Littlewoodā€™s career spanned documentary (radio recordings made with Ewan MacColl in the North of England in the 1930s) to directing for the stage and the running of the Theatre Royal in Londonā€™s Stratford East, often selecting material which aroused memories in local audiences (Leach 2006: 142). Many of the actors trained in her Theatre Workshop subsequently became better known for their appearances on film and television. Littlewood herself directed hardly any material for the screen: Sparrows Canā€™t Sing and a 1964 series of television commercials for the British Egg Marketing Board, starring Theatre Workshopā€™s Avis Bunnage, were rare excursions into an area of practice which she found constraining and unamenable (Gable 1980: 32). The hybridity and singularity of Littlewoodā€™s feature may answer, in some degree, for its subsequent neglect. However, Sparrows Canā€™t Sing makes a significant contribution to a group of films made in Britain in the 1960s which comment generally on changes in the urban and social fabric. It is especially worthy of consideration, I shall argue, for the use which Littlewood made of a particular communityā€™s attitudes ā€“ sentimental and critical ā€“ to such changes and for its amalgamation of an attachment to documentary techniques (recording an aural landscape on location) with a preference for nonnaturalistic delivery in performance

    Implementation and second-year impacts for New Deal 25 Plus customers in the UK Employment Retention and Advancement (ERA) demonstration

    Get PDF
    This report presents findings on the implementation and effectiveness of Britain's Employment Retention and Advancement (ERA) demonstration programme for New Deal 25 Plus customers (ND25 Plus) two years after entering the programme. The effectiveness of this programme is being evaluated using a random assignment research design. Over 16,000 people were randomly assigned onto the programme, making this study one of the largest randomised social policy trials ever undertaken in Britain. The analysis relies heavily on data from two waves of a longitudinal customer survey administered at 12 and 24 months respectively, following each individual's date of random assignment (when they entered the study). The survey respondents (around 6,000) are a representative sub-sample of the full sample of ND25 Plus customers enrolled in the study. The analysis also used data on employment, earnings and benefits receipt from administrative records for the entire sample. To provide a richer understanding of the Jobcentre Plus offices' experience of implementing ERA and customers experiences of ERA, the analysis also uses qualitative research involving in-depth interviews with ERA staff and customers
