    What can professionals do to support mothers whose previous children have been removed: an exploratory study

    Get PDF
    "As senior social workers working in an inner London borough’s front line child protection service for five to six years we have been struck by the fact that the same families become the subjects of safeguarding concerns time and again, often with similar outcomes for subsequent children, in terms of them being removed into substitute care via care proceedings. We were interested in exploring whether there may be more innovative ways of working with parents to enable more children to successfully remain in their parents care.

    Uniformity Studies of Scintillator Tiles directly coupled to SiPMs for Imaging Calorimetry

    Full text link
    We present a novel geometry of scintillator tiles developed for fiberless coupling to silicon photomultipliers (SiPMs) for applications in highly granular calorimeters. A high degree of uniformity of the tile response over the full active area was achieved by a drilled slit at the coupling position of the photon sensor with 2 mm, 4 mm and 5.5 mm in height, width and depth. Detailed measurements of the response to penetrating electrons were performed for tiles with a lateral size of 3 x 3 cm^2 and thicknesses of 5 mm and 3 mm.Comment: 6 pages, 8 figures, accepted by NIM

    Exploring the Spin Structure of the Proton with Two-Body Partonic Scattering at RHIC

    Get PDF
    The STAR collaboration at the Relativistic Heavy Ion Collider is using polarized proton beams at sqrt{s} = 200 GeV to study the spin structure of the proton. The first results for the double spin helicity dependence of inclusive jet production are presented along with projections for additional data taken in 2005 and 2006. When fully analyzed these data sets should place strong constraints on the possible contribution of gluonic spin to the proton spin as expressed by Delta G. Future studies using 2-jet or photon-jet coincidences to map out the gluon spin distribution vs. the gluon's momentum fraction of the proton are discussed.Comment: 4 pages, 2 figures, presented at the 18th Int. IUPAP Conf. on Few-Body Problems in Physics, Santos, Sao Paulo, Brazil, August 21-26,200

    Will China\u27s 12th Five Year Plan Allow for Sufficient Nuclear Power to Support Its Booming Economy in the Next Twenty Years?

    Get PDF
    A major part of China’s 12th Five Year Plan focuses on energy conservation and environmental protection. Its 12th Year Environmental Plan provides that China will increase its nuclear capacity by 30% from 2010 levels of 10.8 gigawatts to 43 gigawatts in 2014. Two questions arise from this plan. First, will enough energy be produced from other sources to supply the country’s energy needs or will there be the need for an expansion to its nuclear program? Second, are the locations of its nuclear power plants safe in light of the disaster at the Fukushima nuclear power plant in Japan following the tsunami in early 2011

    The SISCone jet algorithm optimised for low particle multiplicities

    Full text link
    The SISCone jet algorithm is a seedless infrared-safe cone jet algorithm. There exists an implementation which is highly optimised for a large number of final state particles. However, in fixed-order perturbative calculations with a small number of final state particles, it turns out that the computer time needed for the jet clustering of this implementation is comparable to the computer time of the matrix elements. This article reports on an implementation of the SISCone algorithm optimised for low particle multiplicities.Comment: 16 pages, version to be publishe

    Comparative Analysis of Participation and Finances in Programs of the Brookings Parks and Recreation Department

    Get PDF
    The purpose of this study was to conduct and comparative analysis of the nature and frequency of participation in recreation programs of the Brookings Parks and Recreation Department and the sources of revenue used in support of these activities. The study has been deemed significant as the present researcher was unable to fund and evidence that studies on the nature and frequency of participation as related to cost have been attempted. It was hoped that this study might provide a framework for data collection for future studies of a similar nature. The study was designed and conducted to provide Parks and Recreation Departments with information which would help those agencies determine the extent of non-resident participation and assist in the development of policies regarding such participation. It was also believed that the study might be indicative of the recreational needs of the non-resident population and could be taken to the officials in county government for their information in future county recreational support and planning. Finally, the study was significant in that the present researcher was unable to locate many studies relating to problems of rural recreation administration, particularly in the State of South Dakota

    Production of Jets at the Tevatron

    Full text link
    Measurements of the inclusive jet cross section and the dijet angular distribution using data from the Tevatron are presented. Comparisons to NLO QCD show good agreement below 250 GeV, but CDF data show an excess at higher ET; qualitative agreement is seen between the CDF and DO cross sections. Analysis of the dijet angular distributions exclude quark compositeness below 2.1 TeV.Comment: 5 pages, 6 figure

    Sociodemographic and Psychographic Variables in the Senior Travel Market

    Get PDF
    Segmentation of the senior travel market has, until recently, focused on age groupings. Such segmentation has limited practical application, providing little direction for the development of travel services. Furthermore, age segments are not easily accessible for promotional communication. Investigations which segment the market into clusters, based on reasons for travel for example, may be limited to only the sample investigated. This investigation compares segmentation based on the sociodemographic variable of age to a proprietary psychographic segmentation technique. The latter is shown to provide a better view of the senior travel market and has the benefit of known avenues of accessibility. This research investigation was made possible by a grant from the American Association of Retired Persons Andrus Foundation
