    The present research explored the impact of local short break scheme on the strengths and difficulties of disabled adolescents and their parents. At the end of the scheme disabled children (N=11) took part in semi-structured interviews to evaluate their experiences of the scheme. Data was also collected from their parents (N=7), who completed questionnaires measuring their strengths and difficulties (SDQ, Goodman, 2001) and levels of parental stress (PSI, Abdin, 1995). The findings highlighted that short break schemes can have numerous beneficial effects on disabled adolescent’s health, development and wellbeing. Moreover, the findings suggest that these potential benefits extend beyond the scheme participants to their parents. Finally, areas for future developments emerged, including: funding for more resources, development of young people’s skills, implementing more activities, provide a longer scheme and most significantly the need to develop young adult short break schemes to help aid the transition into adulthood for those from 18 years of age

    Reduced regulator dependence of neutron-matter predictions with chiral interactions

    Full text link
    We calculate the energy per particle in infinite neutron matter perturbatively using chiral N3LO two-body potentials plus N2LO three-body forces. The cutoff dependence of the predictions is investigated by employing chiral interactions with different regulators. We find that the inclusion of three-nucleon forces, which are consistent with the applied two-nucleon interaction, leads to a strongly reduced regulator dependence of the results.Comment: 7 pages, 8 figures, 1 table, to be published in Physical Review

    The nuclear matter equation of state with consistent two- and three-body perturbative chiral interactions

    We compute the energy per particle of infinite symmetric nuclear matter from chiral N3LO (next-to-next-to-next-to-leading order) two-body potentials plus N2LO three-body forces. The low-energy constants of the chiral three-nucleon force that cannot be constrained by two-body observables are fitted to reproduce the triton binding energy and the 3H-3He Gamow-Teller transition matrix element. In this way, the saturation properties of nuclear matter are reproduced in a parameter-free approach. The equation of state is computed up to third order in many-body perturbation theory, with special emphasis on the role of the third-order particle-hole diagram. The dependence of these results on the cutoff scale and regulator function is studied. We find that the inclusion of three-nucleon forces consistent with the applied two-nucleon interaction leads to a reduced dependence on the choice of the regulator only for lower values of the cutoff.Comment: 9 pages, 12 figures, 3 tables, to be published in Physical Review C. arXiv admin note: text overlap with arXiv:1209.553

    Chiral nucleon-nucleon forces in nuclear structure calculations

    Get PDF
    Realistic nuclear potentials, derived within chiral perturbation theory, are a major breakthrough in modern nuclear structure theory, since they provide a direct link between nuclear physics and its underlying theory, namely the QCD. As a matter of fact, chiral potentials are tailored on the low-energy regime of nuclear structure physics, and chiral perturbation theory provides on the same footing two-nucleon forces as well as many-body ones. This feature fits well with modern advances in ab-initio methods and realistic shell-model. Here, we will review recent nuclear structure calculations, based on realistic chiral potentials, for both finite nuclei and infinite nuclear matter.Comment: 10 pages, 8 figures, plenary talk presented at "Nucleus-Nucleus 2015" Conference, 21-26 June 2015, Catania, to be published in the "Conference Proceedings" Series of the Italian Physical Societ

    Dominant Nuclear Outflow Driving Mechanisms in Powerful Radio Galaxies

    Get PDF
    In order to identify the dominant nuclear outflow mechanisms in Active Galactic Nuclei, we have undertaken deep, high resolution observations of two compact radio sources (PKS 1549-79 and PKS 1345+12) with the Advanced Camera for Surveys (ACS) aboard the Hubble Space Telescope. Not only are these targets known to have powerful emission line outflows, but they also contain all the potential drivers for the outflows: relativistic jets, quasar nuclei and starbursts. ACS allows the compact nature (<0.15") of these radio sources to be optically resolved for the first time. Through comparison with existing radio maps we have seen consistency in the nuclear position angles of both the optical emission line and radio data. There is no evidence for bi-conical emission line features on the large-scale and there is a divergance in the relative position angles of the optical and radio structure. This enables us to exclude starburst driven outflows. However, we are unable to clearly distinguish between radiative AGN wind driven outflows and outflows powered by relativistic radio jets. The small scale bi-conical features, indicative of such mechanisms could be below the resolution limit of ACS, especially if aligned close to the line of sight. In addition, there may be offsets between the radio and optical nuclei induced by heavy dust obscuration, nebular continuum or scattered light from the AGN.Comment: 9 pages, 8 figures, emulateapj, ApJ Accepte

    Creating a difference – a role for the arts in addressing child wellbeing in conflict-affected areas

    Background Details findings from a project on the potential for arts activities and art therapy to support the mental health and wellbeing of children living in Kashmir. Methods The intervention engaged 30 school children over the course of one year who produced various forms of artwork and performances. In this paper, we report on project impacts, drawing on some of our qualitative measures including observations and interviews. Results Our research details impacts and improvements in areas of emotional expression, belonging, and agency. We also found an important role for schools to create safe, secure, and caring spaces to allow students to express themselves and work through traumatic feelings in a non-judgemental way. Conclusions School-based arts interventions can play an important role in the mental health and wellbeing of children. Critical here, however, are dedicated space, time, and resources to provide a supportive environment and to sustain activity in long-term

    • While it is believed that the Animal Welfare Act is a valuable document, enforcement of its remits need to be strengthened • A range of recommendations are made focusing on the following areas: • The effectiveness of the Animal Welfare Act 2006 with regard to domestic pets • Regulation surrounding the sale of domestic pets, including online sales and advertising • Enforcement of current animal welfare legislation, including prosecution of offences by the police, local authorities, the RSPCA and others • Recommendations include • Introduction of an effective licensing system (for breeders and dog owners) • Bans on selling and advertising dogs on the internet • Community education events for dog owners • Introduction of a competitive system to decide on the authorised animal welfare enforcement agency • Greater investment in ground services such as number of inspector
