“Social Justice Needs to Be Everywhere”: Imagining the Future of Anti-Oppression Education in Teacher Preparation
This article analyzes a social-justice teacher education project in a larger teacher education program in Western Canada. This program-within-a-program took an anti-oppressive education approach designed to help teacher candidates to understand and challenge various forms of inequity and their interconnections. We review the social justice project first, through a descriptive analysis of our teaching, and second, through hour-long qualitative, semistructured interviews with 20 graduates of our program (all beginning teachers). Our alumni provided examples of teaching against the grain and also spoke to the challenges of implementing critical pedagogies. We conclude by providing four key recommendations and reflecting on the implications for future teacher preparation.Cet article analyse un projet de justice sociale dans le cadre d’un important programme de formation des enseignants dans l’Ouest canadien. Ce « programme à l’intérieur d’un programme » a adopté une approche pédagogique contre l’oppression, conçue pour aider les étudiants en pédagogie à comprendre et à remettre en question diverses formes d’iniquité et les liens entre elles. Nous nous penchons sur le programme de justice sociale, d’abord par une analyse descriptive de notre enseignement, ensuite par des entrevues qualitatives et semi-structurées d’une heure auprès de finissants de notre programme (tous débutant leur carrière d’enseignant). Nos anciens ont fourni des exemples d’enseignement à contre-courant et ont évoqué les défis liés à la mise en oeuvre de pédagogies critiques. Nous concluons en présentant quatre recommandations clés et en réfléchissant aux conséquences pour la formation des enseignants à l’avenir

Sensitivity to Sunburn Is Associated with Susceptibility to Ultraviolet Radiation–Induced Suppression of Cutaneous Cell–Mediated Immunity
Skin cancer incidence is highest in white-skinned people. Within this group, skin types I/II (sun sensitive/tan poorly) are at greater risk than skin types III/IV (sun tolerant/tan well). Studies in mice demonstrate that ultraviolet radiation (UVR)-induced suppression of cell-mediated immune function plays an important role in the development of skin cancer and induces a susceptibility to infectious disease. A similar role is suspected in humans, but we lack quantitative human data to make risk assessments of ambient solar exposure on human health. This study demonstrates that ambient levels of solar UVR, typically experienced within 1 h of exposure to noonday summer sunlight, can suppress contact hypersensitivity (CHS) responses in healthy white-skinned humans in vivo (n = 93). There was a linear relationship between increase in erythema and suppression of CHS (P < 0.001), and a moderate sunburn (two minimal erythema doses [2 MED]) was sufficient to suppress CHS in all volunteers by 93%. However, a single suberythemal exposure of either 0.25 or 0.5 MED suppressed CHS responses by 50 and 80%, respectively, in skin types I/II, whereas 1 MED only suppressed CHS by 40% in skin types III/IV. The two- to threefold greater sensitivity of skin types I/II for a given level of sunburn may play a role in their greater sensitivity to skin cancer
The Samurai Project: verifying the consistency of black-hole-binary waveforms for gravitational-wave detection
We quantify the consistency of numerical-relativity black-hole-binary
waveforms for use in gravitational-wave (GW) searches with current and planned
ground-based detectors. We compare previously published results for the
mode of the gravitational waves from an equal-mass
nonspinning binary, calculated by five numerical codes. We focus on the 1000M
(about six orbits, or 12 GW cycles) before the peak of the GW amplitude and the
subsequent ringdown. We find that the phase and amplitude agree within each
code's uncertainty estimates. The mismatch between the modes
is better than for binary masses above with respect to
the Enhanced LIGO detector noise curve, and for masses above
with respect to Advanced LIGO, Virgo and Advanced Virgo. Between the waveforms
with the best agreement, the mismatch is below . We find that
the waveforms would be indistinguishable in all ground-based detectors (and for
the masses we consider) if detected with a signal-to-noise ratio of less than
, or less than in the best cases.Comment: 17 pages, 9 figures. Version accepted by PR
Paediatric 'care closer to home':stake-holder views and barriers to implementation
In this study we explore the views of NHS stakeholders on providing paediatric ‘care closer to home’ (CCTH), in community-based outpatient clinics delivered by consultants. Design: Semi-structured interviews and thematic framework analysis. Setting: UK specialist children's hospital and surrounding primary care trusts. Participants: 37 NHS stakeholders including healthcare professionals, managers, commissioners and executive team members. Results: Participants acknowledged that outreach clinics would involve a change in traditional ways of working and that the physical setting of the clinic would influence aspects of professional practice. Different models of CCTH were discussed, as were alternatives for improving access to specialist care. Participants supported CCTH as a good principle for paediatric outpatient services; however the challenges of setting up and maintaining community clinics meant they questioned how far it could be achieved in practice. Conclusions: The place of service delivery is both an issue of physical location and professional identity. Policy initiatives which ignore assumptions about place, power and identity are likely to meet with limited success
Impact of densitized lapse slicings on evolutions of a wobbling black hole
We present long-term stable and second-order convergent evolutions of an
excised wobbling black hole. Our results clearly demonstrate that the use of a
densitized lapse function extends the lifetime of simulations dramatically. We
also show the improvement in the stability of single static black holes when an
algebraic densitized lapse condition is applied. In addition, we introduce a
computationally inexpensive approach for tracking the location of the
singularity suitable for mildly distorted black holes. The method is based on
investigating the fall-off behavior and asymmetry of appropriate grid
variables. This simple tracking method allows one to adjust the location of the
excision region to follow the coordinate motion of the singularity.Comment: 10 pages, 8 figure
Physiotherapy for sleep disturbance in chronic low back pain: a feasibility randomised controlled trial
<p>Abstract</p> <p>Background</p> <p>Sleep disturbance is becoming increasingly recognised as a clinically important symptom in people with chronic low back pain (CLBP, low back pain >12 weeks), associated with physical inactivity and depression. Current research and international clinical guidelines recommend people with CLBP assume a physically active role in their recovery to prevent chronicity, but the high prevalence of sleep disturbance in this population may be unknowingly limiting their ability to participate in exercise-based rehabilitation programmes and contributing to poor outcomes. There is currently no knowledge concerning the effectiveness of physiotherapy on sleep disturbance in people with chronic low back pain and no evidence of the feasibility of conducting randomized controlled trials that comprehensively evaluate sleep as an outcome measure in this population.</p> <p>Methods/Design</p> <p>This study will evaluate the feasibility of a randomised controlled trial (RCT), exploring the effects of three forms of physiotherapy (supervised general exercise programme, individualized walking programme and usual physiotherapy, which will serve as the control group) on sleep quality in people with chronic low back pain. A presenting sample of 60 consenting patients will be recruited in the physiotherapy department of Beaumont Hospital, Dublin, Ireland, and randomly allocated to one of the three groups in a concealed manner. The main outcomes will be sleep quality (self-report and objective measurement), and self-reported functional disability, pain, quality of life, fear avoidance, anxiety and depression, physical activity, and patient satisfaction. Outcome will be evaluated at baseline, 3 months and 6 months. Qualitative telephone interviews will be embedded in the research design to obtain feedback from a sample of participants' about their experiences of sleep monitoring, trial participation and interventions, and to inform the design of a fully powered future RCT. Planned analysis will explore trends in the data, effect sizes and clinically important effects (quantitative data), and thematic analysis (qualitative data).</p> <p>Discussion</p> <p>This study will evaluate the feasibility of a randomised controlled trial exploring the effects of three forms of physiotherapy (supervised general exercise programme, individualized walking programme and usual physiotherapy, which will serve as the control group) on sleep quality in people with chronic low back pain.</p> <p>Trial Registration</p> <p>Current controlled trial ISRCTN54009836</p
Health care professionals' views of paediatric outpatient non-attendance:Implications for general practice
Background. Non-attendance at paediatric hospital outpatient appointments poses potential risks to children's health and welfare. Prevention and management of missed appointments depends on the perceptions of clinicians and decision makers from both primary and secondary care, including general practitioners (GPs) who are integral to non-attendance follow-up. Objectives. To examine the views of clinical, managerial and executive health care staff regarding occurrence and management of non-attendance at general paediatric outpatient clinics. Methods. A qualitative study using individual semi-structured interviews was carried out at three English Primary Care Trusts and a nearby children's hospital. Interviews were conducted with 37 staff, including GPs, hospital doctors, other health care professionals, managers, executives and commissioners. Participants were recruited through purposive and 'snowball' sampling methods. Data were analysed following a thematic framework approach. Results. GPs focused on situational difficulties for families, while hospital-based staff emphasized the influence of parents' beliefs on attendance. Managers, executives and commissioners presented a broad overview of both factors, but with less detailed views. All groups discussed sociodemographic factors, with non-attendance thought to be more likely in 'chaotic families'. Hospital interviewees emphasized child protection issues and the need for thorough follow-up of missed appointments. However, GPs were reluctant to interfere with parental responsibilities. Conclusion. Parental motivation and practical and social barriers should be considered. Responsibilities regarding missed appointments are not clear across health care sectors, but GPs are uniquely placed to address non-attendance issues and are central to child safeguarding. Primary care policies and strategies could be introduced to reduce non-attendance and ensure children receive the care they require
