Solution‐Focused Coaching of Staff of People With Severe and Moderate Intellectual Disabilities: A Case Series
Authors: Roeden John M. , Maaskant Marian A. , Bannink Fredrike P. , Curfs Leopold M. G. 
Published: September 2012

AbstractSolution‐focused coaching (SFC) represents a short‐term, future‐focused, and person‐directed therapeutic approach that helps people focus on solutions rather than problems. Thirteen cases of SFC of staff dealing with people with severe and moderate intellectual disabilities (S/MID) are described. In all 13 cases, the progress toward the team goal, proactive thinking of staff, and the quality of the relationship (QOR) between staff and people with S/MID were measured directly before SFC, directly after SFC, and 6 weeks after SFC. After SFC, progress toward the team goal was found in seven out of 13 teams, improvement of proactive thinking was found in 5/10 teams and improvement of the QOR was found in 7/13 teams. With regard to individual staff members, improvement of proactive thinking was found in 12/34 staff members and improvement of the QOR was found in 22/42 staff members. The authors note that SFC stimulates dealing with support problems in a behavioral, proactive way and that SFC can be a useful approach to build useful relationships. The findings are in line with results of earlier research on the value of solution‐focused brief therapy applied to carers (parents or professionals) of people with ID. Future investigation of SFC, preferably using a randomized controlled design, could test the hypothesis that SFC can increase self‐efficacy and proactive thinking in teams, can positively alter staff's perceptions of people with ID, and that teams find it a useful approach.
Superluminous supernovae: 56Ni power versus magnetar radiation
Authors: Dessart Luc , Hillier D. John , Waldman Roni , Livne Eli , Blondin Stéphane 
Published: September 2012

Abstract
Much uncertainty surrounds the origin of superluminous supernovae (SNe). Motivated by the discovery of the Type Ic SN 2007bi, we study its proposed association with a pair-instability SN (PISN). We compute stellar evolution models for primordial ∼200 M⊙ stars, simulating the implosion/explosion due to the pair-production instability, and use them as inputs for detailed non-local thermodynamic equilibrium time-dependent radiative transfer simulations that include non-local energy deposition and non-thermal processes. We retrieve the basic morphology of PISN light curves from red supergiant, blue supergiant and Wolf–Rayet (WR) star progenitors. Although we confirm that a progenitor 100 M⊙ helium core (PISN model He100) fits well the SN 2007bi light curve, the low ratios of its kinetic energy and 56Ni mass to the ejecta mass, similar to standard core-collapse SNe, conspire to produce cool photospheres, red spectra subject to strong line blanketing and narrow-line profiles, all conflicting with SN 2007bi observations. He-core models of increasing 56Ni-to-ejecta mass ratio have bluer spectra, but still too red to match SN 2007bi, even for model He125 – the effect of 56Ni heating is offset by the associated increase in blanketing. In contrast, the delayed injection of energy by a magnetar represents a more attractive alternative to reproduce the blue, weakly blanketed and broad-lined spectra of superluminous SNe. The extra heat source is free of blanketing and is not explicitly tied to the ejecta. Experimenting with an ∼9 M⊙ WR-star progenitor, initially exploded to yield an ∼1.6 B SN Ib/c ejecta but later influenced by tunable magnetar-like radiation, we produce a diversity of blue spectral morphologies reminiscent of SN 2007bi, the peculiar Type Ib SN 2005bf and superluminous SN 2005ap-like events.
Transitions in the Chinese market for refined petroleum products
Authors: Leung Guy C.K. , Li Raymond , Walls W.D. 
Published: September 2012

AbstractChina's rapidly rising crude oil consumption has been a cause of concern, both for China's own energy security and the effects this rising demand has on world oil markets. However, one must disaggregate the domestic Chinese demand for petroleum products to reveal what sort of policy options might be sensible. In this research, we provide a simple empirical characterisation of recent transitions in China's market for refined petroleum products. This study discusses the factors that affect the demand for various petroleum products to enhance our understanding of China's oil economy. Policy options currently being considered by China's leaders are discussed in light of our empirical findings.
The economics of Nigeria's petroleum products' subsidy removal debate: Who is right? Who is wrong?
Authors: Asekunowo Victor O. 
Published: September 2012

AbstractThe petroleum products' subsidy removal proposal slated to take effect from early 2012 in Nigeria has generated a lot war of words between governments in the country, the Nigerian Labour Congress and the civil society. This war of words has, on occasion, regrettably degenerated into violence, culminating in loss of lives and properties. This paper looks at the economics behind the positions taken by the groups on both sides of the divide. The review conducted revealed that the arguments presented by each side cannot be adjudged to have dwarfed the other. However, the review also revealed that the Nigerian poor, who probably due to initial distribution or some other vicissitudes of life, would suffer immeasurably if the subsidy is totally withdrawn. This paper therefore argued that a middle ground, partial withdrawal of subsidy policy must be adopted in which the administration of the scheme, if reformed, would make less targeting errors, i.e. subsidy should be better targeted. This way, the already unimpressive Human Development Index of Nigeria would not worsen.
INSTITUTIONAL WAGE EFFECTS: REVISITING UNION AND BARGAINING COUNCIL WAGE PREMIA IN SOUTH AFRICA
Authors: BHORAT HAROON , GOGA SUMAYYA , VAN DER WESTHUIZEN CARLENE 
Published: September 2012

AbstractThe literature on the union wage gap in South Africa is extensive, spanning a range of data sets and methodologies. There is, however, little consensus on the appropriate method to correct for the endogeneity of union membership or the size of the union wage gap. Furthermore, there are very few studies on the bargaining council wage premium in South Africa because of lack of data on the coverage of employees under these agreements. Our study, using 2005 Labour Force Survey data, firstly reconsiders the union wage gap controlling for both firm‐level and job characteristics. When correcting for the endogeneity of union status through a two‐stage selection model and including firm size, type of employment, and non‐wage benefits, we find a much lower union wage premium for African workers in the formal sector than premiums reported in some previous studies. Secondly, our study estimates bargaining council wage premiums for the private and public sectors. We find that extension procedures are present in both private and public bargaining council systems but that unions negotiate for additional gains for their members at the plant level. Furthermore, there is some evidence that unions negotiate for awards for their members in the private sector irrespective of bargaining council coverage.
RISK–RETURN TRADE‐OFF AND BEHAVIOUR OF VOLATILITY ON THE SOUTH AFRICAN STOCK MARKET: EVIDENCE FROM BOTH AGGREGATE AND DISAGGREGATE DATA
Authors: MANDIMIKA NEVILLE ZIVANAYI , CHINZARA ZIVANEMOYO 
Published: September 2012

AbstractThe study analyses the nature and behaviour of volatility, the risk–return relationship and the long‐term trend of volatility on the South African equity markets using aggregate level, industrial level and sectoral level daily data for the period 1995‐2009. By employing dummy variables for the Asian and the sub‐prime financial crises and the 11 September political shock, the study further examines whether the long‐term trend of volatility structurally breaks during financial crises and major political shocks. Three time‐varying generalised autoregressive conditional heteroskedasticity models were employed: one of them symmetric, and the other two asymmetric. Each of these models was estimated based on three error distributional assumptions. The findings of the study are as follows: First, volatility is largely persistent and asymmetric. Second, risk at both aggregate and disaggregate level is generally not a priced factor on the South Africa (SA) stock market. Third, the threshold autoregressive conditional heteroscedasticity (TARCH) model under the generalised error distribution is the most appropriate model for conditional volatility of the SA stock market. Fourth, volatility generally increases over time, and its trend structurally breaks during financial crises and major global shocks. The policy and investment implications of the findings are outlined.
Accelerating the CM method
Authors: Sutherland Andrew V. 
Published: September 2012

AbstractGiven a prime q and a negative discriminant D, the CM method constructs an elliptic curve E/Fq by obtaining a root of the Hilbert class polynomial HD(X) modulo q. We consider an approach based on a decomposition of the ring class field defined by HD, which we adapt to a CRT setting. This yields two algorithms, each of which obtains a root of HD mod q without necessarily computing any of its coefficients. Heuristically, our approach uses asymptotically less time and space than the standard CM method for almost all D. Under the GRH, and reasonable assumptions about the size of log q relative to ∣D∣, we achieve a space complexity of O((m+n)log q) bits, where mn=h(D) , which may be as small as O(∣D∣1/4 log q) . The practical efficiency of the algorithms is demonstrated using ∣D∣>1016 and q≈2256, and also ∣D∣>1015 and q≈233220. These examples are both an order of magnitude larger than the best previous results obtained with the CM method.

Two simple clinical tests for predicting onset of medial tibial stress syndrome: shin palpation test and shin oedema test
Authors: Newman Phil , Adams Roger , Waddington Gordon 
Published: September 2012

ObjectiveTo examine the relationship between two clinical test results and future diagnosis of (Medial Tibial Stress Syndrome) MTSS in personnel at a military trainee establishment.DesignData from a preparticipation musculoskeletal screening test performed on 384 Australian Defence Force Academy Officer Cadets were compared against 693 injuries reported by 326 of the Officer Cadets in the following 16 months. Data were held in an Injury Surveillance database and analysed using χ2 and Fisher's Exact tests, and Receiver Operating Characteristic Curve analysis.Main outcome measureDiagnosis of MTSS, confirmed by an independent blinded health practitioner.ResultsBoth the palpation and oedema clinical tests were each found to be significant predictors for later onset of MTSS. Specifically: Shin palpation test OR 4.63, 95% CI 2.5 to 8.5, Positive Likelihood Ratio 3.38, Negative Likelihood Ratio 0.732, Pearson χ2 p<0.001; Shin oedema test OR 76.1 95% CI 9.6 to 602.7, Positive Likelihood Ratio 7.26, Negative Likelihood Ratio 0.095, Fisher's Exact p<0.001; Combined Shin Palpation Test and Shin Oedema Test Positive Likelihood Ratio 7.94, Negative Likelihood Ratio <0.001, Fisher's Exact p<0.001. Female gender was found to be an independent risk factor (OR 2.97, 95% CI 1.66 to 5.31, Positive Likelihood Ratio 2.09, Negative Likelihood Ratio 0.703, Pearson χ2 p<0.001) for developing MTSS.ConclusionThe tests for MTSS employed here are components of a normal clinical examination used to diagnose MTSS. This paper confirms that these tests and female gender can also be confidently applied in predicting those in an asymptomatic population who are at greater risk of developing MTSS symptoms with activity at some point in the future.

Published: September 2012

Background—
Abdominal aortic aneurysm (AAA) formation is characterized by inflammation, smooth muscle activation and matrix degradation. This study tests the hypothesis that CD4+ T-cell–produced IL-17 modulates inflammation and smooth muscle cell activation, leading to the pathogenesis of AAA and that human mesenchymal stem cell (MSC) treatment can attenuate IL-17 production and AAA formation.

Methods and Results—

Human aortic tissue demonstrated a significant increase in IL-17 and IL-23 expression in AAA patients compared with control subjects as analyzed by RT-PCR and ELISA. AAA formation was assessed in C57BL/6 (wild-type; WT), IL-23
−/−
or IL-17
−/−
mice using an elastase-perfusion model. Heat-inactivated elastase was used as control. On days 3, 7, and 14 after perfusion, abdominal aorta diameter was measured by video micrometry, and aortic tissue was analyzed for cytokines, cell counts, and IL-17–producing CD4+ T cells. Aortic diameter and cytokine production (MCP-1, RANTES, KC, TNF-α, MIP-1α, and IFN-γ) was significantly attenuated in elastase-perfused IL-17
−/−
and IL-23
−/−
mice compared with WT mice on day 14. Cellular infiltration (especially IL-17–producing CD4+ T cells) was significantly attenuated in elastase-perfused IL-17
−/−
mice compared with WT mice on day 14. Primary aortic smooth muscle cells were significantly activated by elastase or IL-17 treatment. Furthermore, MSC treatment significantly attenuated AAA formation and IL-17 production in elastase-perfused WT mice.

Conclusions—
These results demonstrate that CD4+ T-cell–produced IL-17 plays a critical role in promoting inflammation during AAA formation and that immunomodulation of IL-17 by MSCs can offer protection against AAA formation.
Effect of Complete Revascularization on 10-Year Survival of Patients With Stable Multivessel Coronary Artery Disease

Published: September 2012

Background—
The importance of complete revascularization remains unclear and contradictory. This current investigation compares the effect of complete revascularization on 10-year survival of patients with stable multivessel coronary artery disease (CAD) who were randomly assigned to percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG).

Methods and Results—

This is a post hoc analysis of the Second Medicine, Angioplasty, or Surgery Study (MASS II), which is a randomized trial comparing treatments in patients with stable multivessel CAD, and preserved systolic ventricular function. We analyzed patients who underwent surgery (CABG) or stent angioplasty (PCI). The survival free of overall mortality of patients who underwent complete (CR) or incomplete revascularization (IR) was compared. Of the 408 patients randomly assigned to mechanical revascularization, 390 patients (95.6%) underwent the assigned treatment; complete revascularization was achieved in 224 patients (57.4%), 63.8% of those in the CABG group and 36.2% in the PCI group (
P
=0.001). The IR group had more prior myocardial infarction than the CR group (56.2%×39.2%,
P
=0.01). During a 10-year follow-up, the survival free of cardiovascular mortality was significantly different among patients in the 2 groups (CR, 90.6% versus IR, 84.4%;
P
=0.04). This was mainly driven by an increased cardiovascular specific mortality in individuals with incomplete revascularization submitted to PCI (
P
=0.05).

Conclusions—
Our study suggests that in 10-year follow-up, CR compared with IR was associated with reduced cardiovascular mortality, especially due to a higher increase in cardiovascular-specific mortality in individuals submitted to PCI.

Clampless Off-Pump Versus Conventional Coronary Artery Revascularization
Authors: Börgermann Jochen , Hakim Kavous , Renner André , Parsa Amin , Aboud Anas , Becker Tobias , Masshoff Marc , Zittermann Armin , Gummert Jan Fritz , Kuss Oliver 
Published: September 2012

Background—
This study aimed to assess if clampless off-pump coronary artery bypass grafting (CABG) decreases risk-adjusted mortality, stroke rate, and morbidity in unselected patients in comparison to conventional CABG.

Methods and Results—

Between July 2009 and November 2010, data of 1282 consecutive patients undergoing isolated CABG were prospectively recorded. In 30.8% (n=395), clampless off-pump revascularization was used, either with the PAS-Port automated central venous anastomosis system (n=310) or as total arterial revascularization without central anastomoses (n=85). Propensity score (PS) matching was performed based on 15 preoperative risk variables to correct for selection bias. In-hospital mortality and stroke rate as primary end point, as well as major complications and follow-up outcome of clampless off-pump (lessOPCAB) and conventional CABG (cCABG) were compared in 394 matched patient pairs (total: 788 patients). The clampless off-pump technique decreased the in-hospital rate of death (odds ratio, 0.25; 95% confidence interval, 0.05–1.18,
P
=0.080) and stroke (odds ratio, 0.36; 95% confidence interval, 0.13–0.99,
P
=0.048) significantly. Complications such as low cardiac output syndrome, prolonged ventilation and rethoracotomy were also reduced by lessOPCAB. Over a 2-year follow-up period overall survival, cerebrovascular and major adverse event rate were significantly lower in the lessOPCAB group, while the repeat revascularization rate was comparable.

Conclusions—
In a retrospective PS-matched analysis, clampless off-pump CABG lowers mortality, stroke rate and other morbidity in an unselected group of patients with coronary artery disease.
