    Women’s narratives on their interactions with the first response police officer following an incidence of domestic violence in the UK

    Historically police responses towards the treatment of domestic disturbances regard them as a noncriminal problem. Recent changes to societal and Criminal Justice System attitudes to domestic violence now places an emphasis on first response officers to effectively deal with offenders, manage victim safety and gather evidence. This study explored fifteen women’s interactions with the attending first response police officer following an episode of domestic violence within the home. A qualitative approach using unstructured narrative interviews was chosen to ensure that each woman remained in control of the research interview. Thematic analysis revealed three main themes concerning power relations and officer attitudes, suggesting that personal and cultural factors may negatively impact on officers’ handling of complaints of partner assault, offsetting policy initiatives that guide officers in engaging with victims of domestic violence. The order of the themes reflects the sequential nature of the women’s dialogue. The first theme explores the initial police response, followed by the women’s narratives around feelings of personal disregard for their experiences and evidential considerations. The final theme explores the police response to retraction of statements. Women’s interactions with first response officers following domestic violence illuminates societal issues previously unmentioned. Making womens’ stories visible provides an important insight, contribution and opportunity to examine first response officer’s responses to domestic violence. Integrating the voices of the women (service users) themselves, is arguably an advantageous consideration towards continuing professional development training for all first response police officers

    rp-Process weak-interaction mediated rates of waiting-point nuclei

    Full text link
    Electron capture and positron decay rates are calculated for neutron-deficient Kr and Sr waiting point nuclei in stellar matter. The calculation is performed within the framework of pn-QRPA model for rp-process conditions. Fine tuning of particle-particle, particle-hole interaction parameters and a proper choice of the deformation parameter resulted in an accurate reproduction of the measured half-lives. The same model parameters were used to calculate stellar rates. Inclusion of measured Gamow-Teller strength distributions finally led to a reliable calculation of weak rates that reproduced the measured half-lives well under limiting conditions. For the rp-process conditions, electron capture and positron decay rates on 72^{72}Kr and 76^{76}Sr are of comparable magnitude whereas electron capture rates on 78^{78}Sr and 74^{74}Kr are 1--2 orders of magnitude bigger than the corresponding positron decay rates. The pn-QRPA calculated electron capture rates on 74^{74}Kr are bigger than previously calculated. The present calculation strongly suggests that, under rp-process conditions, electron capture rates form an integral part of weak-interaction mediated rates and should not be neglected in nuclear reaction network calculations as done previously.Comment: 13 pages, 4 figures, 4 tables; Astrophysics and Space Science (2012

    The rp-process and new measurements of beta-delayed proton decay of light Ag and Cd isotopes

    Full text link
    Recent network calculations suggest that a high temperature rp-process could explain the abundances of light Mo and Ru isotopes, which have long challenged models of p-process nuclide production. Important ingredients to network calculations involving unstable nuclei near and at the proton drip line are β\beta-halflives and decay modes, i.e., whether or not β\beta-delayed proton decay takes place. Of particular importance to these network calculation are the proton-rich isotopes 96^{96}Ag, 98^{98}Ag, 96^{96}Cd and 98^{98}Cd. We report on recent measurements of β\beta-delayed proton branching ratios for 96^{96}Ag, 98^{98}Ag, and 98^{98}Cd at the on-line mass separator at GSI.Comment: 4 pages, uses espcrc1.sty.

    Total differential cross sections for Ar–CH4 from an ab initio potential

    Get PDF
    Total differential cross sections for the Ar–CH4 scattering complex at ECM=90.1 meV were obtained from converged close-coupling calculations based on a recent ab initio potential computed by symmetry-adapted perturbation theory (SAPT). Agreement with experiment is good, which demonstrates the accuracy of the SAPT potential

    Thermonuclear Reaction Rate of 23Mg(p,gamma)24$Al

    Full text link
    Updated stellar rates for the reaction 23Mg(p,gamma)24Al are calculated by using all available experimental information on 24Al excitation energies. Proton and gamma-ray partial widths for astrophysically important resonances are derived from shell model calculations. Correspondences of experimentally observed 24Al levels with shell model states are based on application of the isobaric multiplet mass equation. Our new rates suggest that the 23Mg(p,gamma)24Al reaction influences the nucleosynthesis in the mass A>20 region during thermonuclear runaways on massive white dwarfs.Comment: 13 pages (uses Revtex) including 3 postscript figures (uses epsfig.sty), accepted for publication in Phys.

    Ultracold collisions of oxygen molecules

    Full text link
    Collision cross sections and rate constants between two ground- state oxygen molecules are investigated theoretically at translational energies below ∼1\sim 1K and in zero magnetic field. We present calculations for elastic and spin- changing inelastic collision rates for different isotopic combinations of oxygen atoms as a prelude to understanding their collisional stability in ultracold magnetic traps. A numerical analysis has been made in the framework of a rigid- rotor model that accounts fully for the singlet, triplet, and quintet potential energy surfaces in this system. The results offer insights into the effectiveness of evaporative cooling and the properties of molecular Bose- Einstein condensates, as well as estimates of collisional lifetimes in magnetic traps. Specifically, 17O2^{17}O_{2} looks like a good candidate for ultracold studies, while 16O2^{16}O_{2} is unlikely to survive evaporative cooling. Since 17O2^{17}O_{2} is representative of a wide class of molecules that are paramagnetic in their ground state we conclude that many molecules can be successfully magnetically trapped at ultralow temperatures.Comment: 15 pages, 9 figure
