    Older LGBTQI+ people: a protocol for a systematic review of their experiences of receiving home care services in the community

    Get PDF
    To examine older (over 60 years) LGBTQI+ people’s perceptions and experiences of using home care services. The review aims to answer the following questions: 1. What are the experiences or perceptions of older (over 60 years) LGBTQI+ people in using formal home care services? 2. What impact (if any) do these experiences have on the physical and mental health of those utilising home care services? 3. What are the barriers and facilitators to accessing these services

    Interactive analysis of a large aperture Earth observations satellite

    Get PDF
    A system level design and analysis has been conducted on an Earth Observation Satellite (EOS) system using the Interactive Design and Evaluation of Advanced Spacecraft (IDEAS) computer-aided design and analysis program. The IDEAS program consists of about 40 user-friendly technical modules and an interactive graphics display. The reflector support system and feed mast of the EOS spacecraft are constructed with box-truss structural concept, a lattice configuration which can be packaged for delivery in a single Shuttle flight and deployed in orbit. The deployed spacecraft consists of a 120-m by 60-m parabolic focal axis. The spacecraft was modeled for structural, thermal, and control systems analysis and structural elements were designed. On-orbit dynamic and thermal loading analyses were conducted; spacecraft weights and developmental and first unit costs were determined

    Some properties of Potato Virus M (PVM) in Crude Sap and in Pure Preparations

    A study was performed to determine some properties of the potato virus M (PVM) in crude sap and in pure preparations. In crude sap the virus was shown to have a dilution end point value of 10- 4, longevity in vitro particles sedimented as one peak with a sedimentation coefficient value of 162 s. The buoyant density in cesium chloride was 1.304 gm/cm ~ Electrophoresis in polyacrylamide gels showed that the virus possessed only one protein subunit with a molecular weight of 39,300 daltons

    Massive stars in the hinterland of the young cluster, Westerlund 2

    Get PDF
    Accepted for publication in MNRAS, 13 July 2018. 16 pages, plus one-page table in an appendix.An unsettled question concerning the formation and distribution of massive stars is whether they must be born in massive clusters and, if found in less dense environments, whether they must have migrated there. With the advent of wide-area digital photometric surveys, it is now possible to identify massive stars away from prominent Galactic clusters without bias. In this study we consider 40 candidate OB stars found in the field around the young massive cluster, Westerlund 2, by Mohr-Smith et al.: these are located inside a box of 1.5 × 1.5 deg 2 and are selected on the basis of their extinctions and K magnitudes.We present VLT/X-shooter spectra of two of the hottest O stars, respectively 11 and 22 arcmin from the centre of Westerlund 2. They are confirmed as O4V stars, with stellar masses likely to be in excess of 40 M ·. Their radial velocities relative to the non-binary reference object, MSP 182, in Westerlund 2 are -29.4 ± 1.7 and -14.4 ± 2.2 km s -1, respectively. Using Gaia DR2 proper motions we find that between 8 and 11 early O/WR stars in the studied region (including the two VLT targets, plus WR 20c and WR 20aa) could have been ejected fromWesterlund 2 in the last one million years. This represents an efficiency of massive-star ejection of up to ~ 25 per cent. On sky, the positions of these stars and their proper motions show a near N-S alignment. We discuss the possibility that these results are a consequence of prior sub-cluster merging combining with dynamical ejection.Peer reviewe

    Integrated dementia care: A qualitative evidence synthesis of the experiences of people living with dementia, informal carers and healthcare professionals.

    Get PDF
    In order to provide improved care provision, integrated care services are being developed. However, little is known about how people living with dementia, their families and healthcare professionals experience integrated care. Therefore, the purpose of this review of the qualitative literature was to examine the experiences and perceptions of integrated dementia care. This qualitative review synthesised findings from included studies identified from a comprehensive literature search. Searches included: five electronic databases, journal handsearching, and reference list searching of relevant literature reviews and the final included studies. Three overarching themes were identified: 1) Ways of working which facilitate the delivery of integrated dementia care; 2) Informal carers as equal partners in care provision and decision making; and 3) Challenges leading to fragmented and disjointed integrated dementia care. For integrated care to be successful, communication and collaboration between healthcare professionals, and the involvement of informal carers is needed. Multidisciplinary teams and employing case managers to coordinate care provision can improve communication and collaboration. However, distrust between healthcare professionals and a lack of a central database to access and share information often hinders the development of integrated dementia care service provision. Integrated dementia care can be successful and well received by people living with dementia and their families when certain conditions are met. However, given the negative consequences fragmented and disjointed care can have on people living with dementia and their families, action is needed to further support the development of integrated dementia care services.

    Competitive intelligence programmes at French Chambers of Commerce and Industry.

    Get PDF
    Over the last ten years France has implemented regional programmes to increase the awareness of, and change attitudes towards, the Competitive Intelligence (CI) practices of enterprises. The emphasis has been on Small and Medium-sized Enterprises (SMEs) with the Chambers of Commerce and Industry (CCI) playing a central role. This is an important part of a national state effort to improve and focus a company’s strategic management of information in both defensive and offensive modes. This report is a summary of 15 semi-structured interviews undertaken with French Chambers of Commerce and Industry in 2009. These form the foundation for future work on identifying the roles of awarenessand attitudes as influence drivers in the competitive intelligence processes of SMEs in France

    Collective oscillations of a Fermi gas in the unitarity limit: Temperature effects and the role of pair correlations

    Full text link
    We present detailed measurements of the frequency and damping of three different collective modes in an ultracold trapped Fermi gas of 6^6Li atoms with resonantly tuned interactions. The measurements are carried out over a wide range of temperatures. We focus on the unitarity limit, where the scattering length is much greater than all other relevant length scales. The results are compared to theoretical calculations that take into account Pauli blocking and pair correlations in the normal state above the critical temperature for superfluidity. We show that these two effects nearly compensate each other and the behavior of the gas is close to the one of a classical gas.Comment: 8 pages, 5 figure

    Group selection models in prebiotic evolution

    Full text link
    The evolution of enzyme production is studied analytically using ideas of the group selection theory for the evolution of altruistic behavior. In particular, we argue that the mathematical formulation of Wilson's structured deme model ({\it The Evolution of Populations and Communities}, Benjamin/Cumings, Menlo Park, 1980) is a mean-field approach in which the actual environment that a particular individual experiences is replaced by an {\it average} environment. That formalism is further developed so as to avoid the mean-field approximation and then applied to the problem of enzyme production in the prebiotic context, where the enzyme producer molecules play the altruists role while the molecules that benefit from the catalyst without paying its production cost play the non-altruists role. The effects of synergism (i.e., division of labor) as well as of mutations are also considered and the results of the equilibrium analysis are summarized in phase diagrams showing the regions of the space of parameters where the altruistic, non-altruistic and the coexistence regimes are stable. In general, those regions are delimitated by discontinuous transition lines which end at critical points.Comment: 22 pages, 10 figure
