    Despite the growing awareness of the significance of helping a relative to relocate to a care home as a key phase in the care-giving career, relatively few British studies have explored this experience in depth. Informed by a constructivist perspective, this study sought a better understanding of nursing home placements from the viewpoint of relatives. Data were collected in 37 semi-structured interviews involving 48 people who had assisted a close relative to move into a nursing home. Analysis revealed three perceived phases to the transition: ‘making the best of it’, ‘making the move’ and ‘making it better’. The relatives' experiences through these phases had five perceived elements, all of which were continua, from absent to very strong, reflecting the extent to which they were felt. They were: operating ‘under pressure’ or not; ‘in the know’ or ‘working in the dark’; ‘working together’ or ‘working alone’; ‘in control of events’ or not, and ‘supported’ or ‘unsupported’ both practically and emotionally. This paper reports findings about the first phase of the transition, ‘making the best of it’, and documents the experiences of decision-making about nursing home placements. It is argued that health and social care practitioners have enormous potential to influence whether or not helping a relative to move into a nursing home is perceived as a positive choice

    Policy responses to regional unemployment:Lessons from Germany, Spain and Italy

    Get PDF
    The paper examines the causes of high regional unemployment in Germany, Spain and Italy, and identifies a number of areas where policy action is needed. Lower unemployment rates will not only depend on stability-oriented macroeconomic policies and a sufficiently flexible labour market, but also on moves towards more decentralised wage bargaining systems; efforts to reduce regions' long-term dependency on fiscal transfers; changes in tax-benefit systems to improve incentives to create and take up jobs; efficient public expenditure on physical and human capital and action to reduce obstacles to labour mobility.labour force,wages,policy changes,labour mobility,European Economy.

    Close Approach during Hard Binary--Binary Scattering

    Full text link
    We report on an extensive series of numerical experiments of binary--binary scattering, analysing the cross--section for close approach during interactions for a range of hard binary parameters of interest in globular cluster cores. We consider the implied rate for tidal interactions for different globular clusters and compare our results with previous, complementary estimates of stellar collision rates in globular clusters. We find that the collision rate for binary--binary encounters dominates in low density clusters if the binary fraction in the cluster is larger than 0.20.2 for wide main--sequence binaries. In dense clusters binary--single interactions dominate the collision rate and the core binary fraction must be \ltorder 0.1 per decade in semi--major axis or too many collisions take place compared to observations. The rates are consistent if binaries with semi--major axes ∌100AU\sim 100 AU are overabundant in low density clusters or if breakup and ejection substantially lowers the binary fraction in denser clusters. Given reasonable assumptions about fractions of binaries in the cores of low density clusters such as NGC~5053, we cannot account for all the observed blue stragglers by stellar collisions during binary encounters, suggesting a substantial fraction may be due to coalescence of tight primordial binaries.Comment: 13 pages including 13 ps figures.

    How to Recover a Qubit That Has Fallen Into a Black Hole

    Get PDF
    We demonstrate an algorithm for the retrieval of a qubit, encoded in spin angular momentum, that has been dropped into a no-firewall black hole. Retrieval is achieved analogously to quantum teleportation by collecting Hawking radiation and performing measurements on the black hole. Importantly, these methods only require the ability to perform measurements from outside the event horizon.Comment: 6 pages v2: modified protocol to discuss total angular momentum, corrected typos, added references v3: updated with referee feedbac

    Consistent analysis of neutral- and charged-current neutrino scattering off carbon

    Full text link
    Background: Good understanding of the cross sections for (anti)neutrino scattering off nuclear targets in the few-GeV energy region is a prerequisite for correct interpretation of results of ongoing and planned oscillation experiments. Purpose: Clarify possible source of disagreement between recent measurements of the cross sections on carbon. Method: Nuclear effects in (anti)neutrino scattering off carbon nucleus are described using the spectral function approach. The effect of two- and multi-nucleon final states is accounted for by applying an effective value of the axial mass, fixed to 1.23 GeV. Neutral-current elastic (NCE) and charged-current quasielastic (CCQE) processes are treated on equal footing. Results: The differential and total cross sections for the energy ranging from a few hundreds of MeV to 100 GeV are obtained and compared to the available data from the BNL E734, MiniBooNE, and NOMAD experiments. Conclusions: Nuclear effects in NCE and CCQE scattering seem to be very similar. Within the spectral function approach, the axial mass from the shape analysis of the MiniBooNE data is in good agreement with the results reported by the BNL E734 and NOMAD Collaborations. However, the combined analysis of NCE and CCQE data does not seem to support the contribution of multi-nucleon final states being large enough to explain the normalization of the MiniBooNE-reported cross sections.Comment: 14 pages, 9 figures, detailed discussion of the role of FSI is adde

    The Low Surface Brightness Extent of the Fornax Cluster

    Get PDF
    We have used a large format CCD camera to survey the nearby Fornax cluster and its immediate environment for low luminosity low surface brightness galaxies. Recent observations indicate that these are the most dark matter dominated galaxies known and so they are likely to be a good tracer of the dark matter in clusters. We have identified large numbers of these galaxies consistent with a steep faint end slope of the luminosity function (alpha~ -2) down to MB ~ -12. These galaxies contribute almost the same amount to the total cluster light as the brighter galaxies and they have a spatial extent that is some four times larger. They satisfy two of the important predictions of N-body hierarchical simulations of structure formation using dark halos. The luminosity (mass ?) function is steep and the mass distribution is more extended than that defined by the brighter galaxies. We also find a large concentration of low surface brightness galaxies around the nearby galaxy NGC1291.Comment: 16 pages, 6 figure

    Optical/near-infrared colours of early-type galaxies and constraints on their star formation histories

    Get PDF
    (abridged) We introduce and discuss the properties of a theoretical (B-K)-(J-K) integrated colour diagram for single-age, single-metallicity stellar populations. This combination of integrated colours is able to largely disentangle the well known age-metallicity degeneracy when the age of the population is greater than ~300 Myr. We discuss in detail the effect on this colour-colour diagram of alpha-enhanced metal abundance ratios, the presence of blue horizontal branch stars unaccounted for in the theoretical calibration, and of statistical colour fluctuations in low mass stellar systems. In the case of populations with multiple stellar generations, the luminosity-weighted mean age obtained from this diagram is shown to be heavily biased towards the youngest stellar components. We apply this method to several datasets for which optical and near-IR photometry are available in the literature. For the two Local Group dwarf galaxies NGC185 and NGC6822, the mean ages derived from the integrated colours are consistent with the star formation histories inferred independently from photometric observations of their resolved stellar populations. A sample of bright field and Virgo cluster elliptical galaxies is found to exhibit a range of luminosity-weighted mean ages from 3 to 14 Gyr, with a mean of 8 Gyr, independent of environment, and mean metallicities at or just above the solar value. Colour gradients are found in all of the galaxies studied, in the sense that central regions are redder. Aperture data for five Virgo early-type dwarf galaxies show that these galaxies appear to be shifted to lower mean metallicities and lower mean ages (range 1 to 6 Gyr) than their higher luminosity counterparts.Comment: (1) Liverpool John Moores University, UK; (2) University of Cardiff, UK; (3) University of Bristol, UK; (4) INAF-Osservatorio Astronomico di Collurania, I; 12 pages, 9 figures, MNRAS in pres
