Improving pupil group work interaction and dialogue in primary classrooms : Results from a year-long intervention study
Findings are reported from a year-long evaluation of the effectiveness of the SPRinG programme relative to a control group. SPRinG aimed to address the wide gap between the potential of group interaction to promote learning and its limited use in schools. The project involved working with teachers to develop strategies for enhancing pupil group-work and dialogue, and to implement a pupil relational and group skills training programme. Video observations were conducted of a sub-sample of pupil groups (31 SPRinG; 29 Control groups) working on a specially designed group decision-making activity undertaken in everyday classroom settings. SPRinG groups displayed higher levels of participation, engagement, active and sustained discussion, high level inferential joint reasoning and lower levels of group disruptive blocking behaviours. We argue that group-work can be successfully implemented into everyday school classrooms, and improve pupil interactions and high level discussion, provided teachers take time to train pupils in relational and group-working skills
Sound Knowledge: Music and Science in London, 1789-1851
What does it mean to hear scientifically? What does it mean to see musically? This volume uncovers a new side to the long nineteenth century in London, a hidden history in which virtuosic musical entertainment and scientific discovery intersected in remarkable ways.
Sound Knowledge examines how scientific truth was accrued by means of visual and aural experience, and, in turn, how musical knowledge was located in relation to empirical scientific practice. James Q. Davies and Ellen Lockhart gather work by leading scholars to explore a crucial sixty-year period, beginning with Charles Burney’s ambitious General History of Music, a four-volume study of music around the globe, and extending to the Great Exhibition of 1851, where musical instruments were assembled alongside the technologies of science and industry in the immense glass-encased collections of the Crystal Palace. Importantly, as the contributions show, both the power of science and the power of music relied on performance, spectacle, and experiment. Ultimately, this volume sets the stage for a new picture of modern disciplinarity, shining light on an era before the division of aural and visual knowledge
A Two Hour Quasi-Period in an Ultra-luminous X-Ray source in NGC628
Quasi-periodic oscillations and X-ray spectroscopy are powerful probes of
black hole masses and accretion disks, and here we apply these diagnostics to
an ultraluminous X-ray source (ULX) in the spiral galaxy NGC628 (M74). This
object was observed four times over two years with the Chandra X-ray
Observatory and XMM-Newton, with three long observations showing dramatic
variability, distinguished by a series of outbursts with a quasi-period (QPO)
of 4,000-7,000 seconds. This is unique behavior among both ULXs and Galactic
X-ray binaries due to the combination of its burst-like peaks and deep troughs,
its long quasi-periods, its high variation amplitudes of %, and its
substantial variability between observations. The X-ray spectra is fitted by an
absorbed accretion disk plus a power-law component, suggesting the ULX was in a
spectral state analogous to the Low Hard state or the Very High state of
Galactic black hole X-ray binaries. A black hole mass of -- is estimated from the -- scaling relation found in the
Galactic X-ray binaries and active galactic nuclei.Comment: 12 pages, 3 figures. accepted for publication in ApJ Lette
Why is Austerity Governable? A Gramscian Urban Regime Analysis of Leicester, UK
open access articleAusterity has been delivered in the UK, without durably effective resistance. Read through a dialogue between Urban Regime Theory and Gramsci’s theory of the integral state, the paper considers how austerity was normalised and made governable in the city of Leicester. It shows how Leicester navigated waves of crisis, restructuring and austerity, positioning itself as a multicultural city of entrepreneurs. The paper explores historical influences on the development of the local state, inscribed in the politics of austerity governance today. From a regime-theoretical standpoint, it shows how the local state accrued the governing resources to deliver austerity, while disorganising and containing resistance. Imbued with legacies of past-struggles, this process of organised-disorganisation produced a functional hegemony articulated in the multiple subjectivities of “austerian realism”. The paper elaborates six dimensions of Gramscian regime analysis to inform further research

eCook: what behavioural challenges await this potentially transformative concept?
This paper aims to identify and understand the challenges that may confront the scaling up of a proposed battery electric cooking concept (Batchelor 2013), eCook, which offers the potential for emission free cooking, with time/money savings and broader environmental benefits from reduced fuelwood/charcoal consumption. By drawing on the literature on the transition to electric cooking in South Africa and more broadly, literature from across the Global South analysing the uptake of ICS (improved cookstoves), LPG (liquid petroleum gas) and solar home systems, this study identifies the factors (e.g. successful delivery models and marketing strategies) that have enabled these innovations to reach scale. This knowledge is then related to the eCook concept, by identifying the potential users of this promising technology and outlining potential marketing strategies, as well as a user-focused iterative design process, that will enable social enterprises to reach them. Uptake is predicted to be most rapid in hot climates where fuelwood/charcoal is purchased and low energy diets and low power cooking devices are the standard. Mobile enabled fee-for-service (utility) business models, the establishment of a service network, awareness raising campaigns on the benefits of clean cooking, female-focussed training programs and bundling eCook systems with locally appropriate appliances to enable productive activities are seen as key to reaching scale
Crazy heart: kinematics of the "star pile" in Abell 545
We study the structure and internal kinematics of the "star pile" in Abell
545 - a low surface brightness structure lying in the center of the cluster.We
have obtained deep long-slit spectroscopy of the star pile using VLT/FORS2 and
Gemini/GMOS, which is analyzed in conjunction with deep multiband CFHT/MEGACAM
imaging. As presented in a previous study the star pile has a flat luminosity
profile and its color is consistent with the outer parts of elliptical
galaxies. Its velocity map is irregular, with parts being seemingly associated
with an embedded nucleus, and others which have significant velocity offsets to
the cluster systemic velocity with no clear kinematical connection to any of
the surrounding galaxies. This would make the star pile a dynamically defined
stellar intra-cluster component. The complicated pattern in velocity and
velocity dispersions casts doubts on the adequacy of using the whole star pile
as a dynamical test for the innermost dark matter profile of the cluster. This
status is fulfilled only by the nucleus and its nearest surroundings which lie
at the center of the cluster velocity distribution.Comment: Accepted for publication in A&A. 10 pages & 6 figure
The Effectiveness and Cost-Effectiveness of Spinal Cord Stimulation for Refractory Angina (RASCAL Study): A Pilot Randomized Controlled Trial
Background:
Patients with “refractory angina” (RA) unsuitable for coronary revascularization experience high levels of hospitalization and poor health‐related quality of life. Randomized trials have shown spinal cord stimulation (SCS) to be a promising treatment for chronic stable angina and RA; however, none has compared SCS with usual care (UC). The aim of this pilot study was to address the key uncertainties of conducting a definitive multicenter trial to assess the clinical and cost‐effectiveness of SCS in RA patients, i.e., recruitment and retention of patients, burden of outcome measures, our ability to standardize UC in a UK NHS setting.
Methods:
RA patients deemed suitable were randomized in a 1:1 ratio to SCS plus UC (SCS group) or UC alone (UC group). We sought to assess: recruitment, uptake, and retention of patients; feasibility and acceptability of SCS treatment; the feasibility and acceptability of standardizing UC; and the feasibility and acceptability of the proposed trial outcome measures. Patient outcomes were assessed at baseline (prerandomization) and three and six months postrandomization.
Results:
We failed to meet our planned recruitment target (45 patients) and randomized 29 patients (15 SCS group, 14 UC group) over a 42‐month period across four sites. None of the study participants chose to withdraw following consent and randomization. With exception of two deaths, all completed evaluation at baseline and follow‐up. Although the study was not formally powered to compare outcomes between groups, we saw a trend toward larger improvements in both primary and secondary outcomes in the SCS group.
Conclusions:
While patient recruitment was found to be challenging, levels of participant retention, outcome completion, and acceptability of SCS therapy were high. A number of lessons are presented in order to take forward a future definitive pragmatic randomized trial
