    Despite the frequency with which individuals are currently communicating via forms of technology and the unique features of online communication (i.e., lack of verbal and nonverbal cues, ability to send messages with greater frequency, opportunity to make personal information public, etc.), few studies have considered individuals\u27 perceptions of and experiences with online partner aggression victimization. Through quantitative and qualitative methods, the present research investigated university students\u27 ( N = 349; 82.1% female) experiences of online partner aggression victimization occurring via email, instant messaging, and social networking sites and their perceptions of severity of the aggressive acts. In addition, information was collected about participants\u27 dispositional coping strategies and their psychological and adaptive functioning as well as the indirect effects of coping on associated outcomes. Findings revealed that a large number (82.1%) of participants were victimized by online partner aggression at least once in the past year and that victimization occurred most frequently (71.8%) via instant messaging. Women were found to perceive all categories of online partner aggression as more severe than men. Path analysis indicated that maladaptive coping indirectly affected outcomes for individuals who had experienced online partner aggression such that this method of coping resulted in poorer psychological functioning, but better adaptive functioning. These findings provide support for the seriousness of online partner aggression and the importance of coping style with respect to outcomes. Limitations and clinical implications are discussed

    A peculiar HI cloud near the distant globular cluster Pal 4

    We present 21-cm observations of four Galactic globular clusters, as part of the on-going GALFA-HI Survey at Arecibo. We discovered a peculiar HI cloud in the vicinity of the distant (109 kpc) cluster Pal 4, and discuss its properties and likelihood of association with the cluster. We conclude that an association of the HI cloud and Pal 4 is possible, but that a chance coincidence between Pal 4 and a nearby compact high-velocity cloud cannot be ruled out altogether. New, more stringent upper limits were derived for the other three clusters: M 3, NGC 5466, and Pal 13. We briefly discuss the fate of globular cluster gas and the interaction of compact clouds with the Galactic Halo gas.Comment: Accepted for publication in MNRA

    Thoracic Society of Australia and New Zealand position statement on acute oxygen use in adults : 'swimming between the flags'

    Oxygen is a life-saving therapy but, when given inappropriately, may also be hazardous. Therefore, in the acute medical setting, oxygen should only be given as treatment for hypoxaemia and requires appropriate prescription, monitoring and review. This update to the Thoracic Society of Australia and New Zealand (TSANZ) guidance on acute oxygen therapy is a brief and practical resource for all healthcare workers involved with administering oxygen therapy to adults in the acute medical setting. It does not apply to intubated or paediatric patients. Recommendations are made in the following six clinical areas: assessment of hypoxaemia (including use of arterial blood gases); prescription of oxygen; peripheral oxygen saturation targets; delivery, including non-invasive ventilation and humidified high-flow nasal cannulae; the significance of high oxygen requirements; and acute hypercapnic respiratory failure. There are three sections which provide (1) a brief summary, (2) recommendations in detail with practice points and (3) a detailed explanation of the reasoning and evidence behind the recommendations. It is anticipated that these recommendations will be disseminated widely in structured programmes across Australia and New Zealand

    High Energy Neutrino Signals of Four Neutrino Mixing

    Full text link
    We evaluate the upward shower and muon event rates for two characteristic four neutrino mixing models for extragalactic neutrinos, as well as for the atmospheric neutrinos, with energy thresholds of 1 TeV, 10 TeV and 100 TeV. We show that by comparing the shower to muon event rates, one can distinguish between oscillation and no-oscillation models. By measuring shower and muon event rates for energy thresholds of 10 TeV and 100 TeV, and by considering their ratio, it is possible to use extragalactic neutrino sources to determine the type of four-flavor mixing pattern. We find that one to ten years of data taking with kilometer-size detector has a very good chance of providing valuable information about the physics beyond the Standard Model.Comment: version accepted for publication in Phys.

    This document is the author's original submitted manuscript (pre-print) version. An updated version has been published by MIT Press in Journal of Cold War Studies, available online at doi: https://doi.org/10.1162/JCWS_a_00721.Films and sports played central roles in Cold War popular culture. Each helped set ideological agendas domestically and internationally while serving as powerful substitutes for direct superpower conflict. This article brings film and sport together by offering the first comparative analysis of how U.S. and Soviet cinema used sport as an instrument of propaganda during the Cold War. The article explores the different propaganda styles that U.S. and Soviet sports films adopted and pinpoints the political functions they performed. It considers what Cold War sports cinema can tell us about political culture in the United States and the Soviet Union after 1945 and about the complex battle for hearts and minds that was so important to the East-West conflict.Peer reviewedFinal Published versio

    Effectiveness of pelvic floor muscle training with and without electromyographic biofeedback for urinary incontinence in women: multicentre randomised controlled trial

    This is the final version. Available on open access from BMJ Publishing Group via the DOI in this recordObjective To assess the effectiveness of pelvic floor muscle training (PFMT) plus electromyographic biofeedback or PFMT alone for stress or mixed urinary incontinence in women. Design Parallel group randomised controlled trial. Setting 23 community and secondary care centres providing continence care in Scotland and England. Participants 600 women aged 18 and older, newly presenting with stress or mixed urinary incontinence between February 2014 and July 2016: 300 were randomised to PFMT plus electromyographic biofeedback and 300 to PFMT alone. Interventions Participants in both groups were offered six appointments with a continence therapist over 16 weeks. Participants in the biofeedback PFMT group received supervised PFMT and a home PFMT programme, incorporating electromyographic biofeedback during clinic appointments and at home. The PFMT group received supervised PFMT and a home PFMT programme. PFMT programmes were progressed over the appointments. Main outcome measures The primary outcome was self-reported severity of urinary incontinence (International Consultation on Incontinence Questionnaire-urinary incontinence short form (ICIQ-UI SF), range 0 to 21, higher scores indicating greater severity) at 24 months. Secondary outcomes were cure or improvement, other pelvic floor symptoms, condition specific quality of life, women’s perception of improvement, pelvic floor muscle function, uptake of other urinary incontinence treatment, PFMT self-efficacy, adherence, intervention costs, and quality adjusted life years. Results Mean ICIQ-UI SF scores at 24 months were 8.2 (SD 5.1, n=225) in the biofeedback PFMT group and 8.5 (SD 4.9, n=235) in the PFMT group (mean difference −0.09, 95% confidence interval −0.92 to 0.75, P=0.84). Biofeedback PFMT had similar costs (mean difference £121 ($154; €133), −£409 to £651, P=0.64) and quality adjusted life years (−0.04, −0.12 to 0.04, P=0.28) to PFMT. 48 participants reported an adverse event: for 23 this was related or possibly related to the interventions. Conclusions At 24 months no evidence was found of any important difference in severity of urinary incontinence between PFMT plus electromyographic biofeedback and PFMT alone groups. Routine use of electromyographic biofeedback with PFMT should not be recommended. Other ways of maximising the effects of PFMT should be investigated.National Institute for Health Research (NIHR

    Spinal involvement in mucopolysaccharidosis IVA (Morquio-Brailsford or Morquio A syndrome): presentation, diagnosis and management.

    Get PDF
    Mucopolysaccharidosis IVA (MPS IVA), also known as Morquio-Brailsford or Morquio A syndrome, is a lysosomal storage disorder caused by a deficiency of the enzyme N-acetyl-galactosamine-6-sulphate sulphatase (GALNS). MPS IVA is multisystemic but manifests primarily as a progressive skeletal dysplasia. Spinal involvement is a major cause of morbidity and mortality in MPS IVA. Early diagnosis and timely treatment of problems involving the spine are critical in preventing or arresting neurological deterioration and loss of function. This review details the spinal manifestations of MPS IVA and describes the tools used to diagnose and monitor spinal involvement. The relative utility of radiography, computed tomography (CT) and magnetic resonance imaging (MRI) for the evaluation of cervical spine instability, stenosis, and cord compression is discussed. Surgical interventions, anaesthetic considerations, and the use of neurophysiological monitoring during procedures performed under general anaesthesia are reviewed. Recommendations for regular radiological imaging and neurologic assessments are presented, and the need for a more standardized approach for evaluating and managing spinal involvement in MPS IVA is addressed
