BACKGROUND:
Intraoperative mechanical ventilation may yield lung injury. To date, there is no consensus regarding the best ventilator strategy for abdominal surgery. We aimed to investigate the impact of the mechanical ventilation strategies used in 2 recent trials (Intraoperative Protective Ventilation [IMPROVE] trial and Protective Ventilation using High versus Low PEEP [PROVHILO] trial) on driving pressure (ΔP
RS), mechanical power, and lung damage in a model of open abdominal surgery.

METHODS:
Thirty-five Wistar rats were used, of which 28 were anesthetized, and a laparotomy was performed with standardized bowel manipulation. Postoperatively, animals (n = 7/group) were randomly assigned to 4 hours of ventilation with: (1) tidal volume (V
T) = 7 mL/kg and positive end-expiratory pressure (PEEP) = 1 cm H2O without recruitment maneuvers (RMs) (low V
T/low PEEP/RM−), mimicking the low-V
T/low-PEEP strategy of PROVHILO; (2) V
T = 7 mL/kg and PEEP = 3 cm H2O with RMs before laparotomy and hourly thereafter (low V
T/moderate PEEP/4 RM+), mimicking the protective ventilation strategy of IMPROVE; (3) V
T = 7 mL/kg and PEEP = 6 cm H2O with RMs only before laparotomy (low V
T/high PEEP/1 RM+), mimicking the strategy used after intubation and before extubation in PROVHILO; or (4) V
T = 14 mL/kg and PEEP = 1 cm H2O without RMs (high V
T/low PEEP/RM−), mimicking conventional ventilation used in IMPROVE. Seven rats were not tracheotomized, operated, or mechanically ventilated, and constituted the healthy nonoperated and nonventilated controls.

RESULTS:
Low V
T/moderate PEEP/4 RM+ and low V
T/high PEEP/1 RM+, compared to low V
T/low PEEP/RM− and high V
T/low PEEP/RM−, resulted in lower ΔP
RS (7.1 ± 0.8 and 10.2 ± 2.1 cm H2O vs 13.9 ± 0.9 and 16.9 ± 0.8 cm H2O, respectively; P< .001) and less mechanical power (63 ± 7 and 79 ± 20 J/min vs 110 ± 10 and 120 ± 20 J/min, respectively; P = .007). Low V
T/high PEEP/1 RM+ was associated with less alveolar collapse than low V
T/low PEEP/RM− (P = .03). E-cadherin expression was higher in low V
T/moderate PEEP/4 RM+ than in low V
T/low PEEP/RM− (P = .013) or high V
T/low PEEP/RM− (P = .014). The extent of alveolar collapse, E-cadherin expression, and tumor necrosis factor-alpha correlated with ΔP
RS (r = 0.54 [P = .02], r = −0.48 [P = .05], and r = 0.59 [P = .09], respectively) and mechanical power (r = 0.57 [P = .02], r = −0.54 [P = .02], and r = 0.48 [P = .04], respectively).

CONCLUSIONS:
In this model of open abdominal surgery based on the mechanical ventilation strategies used in IMPROVE and PROVHILO trials, lower mechanical power and its surrogate ΔP
RS were associated with reduced lung damage.

Published: July 2017

Abstract
Quasi-classical trajectory calculations at the DFT level and CVT calculations at the CCSD(T) level are performed to study the dynamics of O(3P) + H2S(1A1) reaction on the lowest triplet potential energy surface. In the dynamics part the potential energy surface has been constructed by interpolation technique following the method introduced by Collins and his coworkers. Total and individual classical reactive cross sections are calculated at collision energies from 13.1 to 126.0 kJ mol−1. The rate constants from QCT calculation are compared with those calculated from canonical variational transition state theory at the G3(MP2)B3 and CCSD(T)/Aug-cc-pVTZ levels. The energy partitioning in reactive collisions for the formation of main products (OH + SH and H + HSO) and in non-reactive collisions for the reactants is investigated. At 52.5 kJ mol−1 initial collision energy about 42% and 49% of the total available energy goes into the translational energy and internal motions of H + HSO products, respectively, while for SH + OH products these quantities were found to be about 25% and 40% of the total available energy. The rest of the available energy is allocated in the rotational degrees.
2-Aminoethanesulfonic Acid Immobilized on Epichlorohydrin Functionalized Fe3O4@WO3 (Fe3O4@WO3-EAE-SO3H): A Novel Magnetically Recyclable Heterogeneous Nanocatalyst for the Green One-Pot Synthesis of 1-Substituted-1H-1,2,3,4-Tetrazoles in Water

Published: July 2017

AbstractIn this research 2-aminoethanesulfonic acid immobilized on epichlorohydrin functionalized Fe3O4@WO3 (Fe3O4@WO3-EAE-SO3H) has been introduced as a novel and efficient magnetic nanocatalyst for appropriate and rapid synthesis of 1-substituted-1H-1,2,3,4-tetrazoles. This new nanocatalyst was then characterized using FT-IR, XRD, TEM, EDS, TGA, FE-SEM, CHNS and VSM techniques. The above experimental results allowed determination of the composition of Fe3O4@WO3-EAE-SO3H and clearly revealed that the nanoparticles are spherical in shape with particle size in the range of 7–23 nm and superparamagnetic behavior. Fe3O4@WO3-EAE-SO3H as an excellent replacement for Brønsted acids was shown to be highly efficient in the rapid preparation of 1-substituted-1H-1,2,3,4-tetrazoles through the cyclization reaction of various primary amines, triethyl orthoformate and 1-butyl-3-methylimidazolium azide ([bmim][N3]). Compared with conventional methods, the present protocol has considerable advantages such as short reaction time, mild reaction conditions, easy work-up, pure products with high yields, catalyst recovery using an external magnet and reuse of the catalyst several times without noticeable deterioration in catalytic activity. In addition to the aforementioned favourable properties, the remarkable feature of the present protocol is the use of water as environmentally benign solvent, which eliminates the use of toxic solvent.
Music technology, education and maps: The use of geospatial technology and data to inform music education research
Authors: Purves Ross M. 
Published: July 2017

Abstract
Recent developments in geographical information systems and geospatial statistics, together with greater access to large, fine-resolution ‘geocoded’ data sets, are transforming environmental, social and economic research. Over the past decade, there has been a small, but growing application of these techniques within the fields of music making, music education and music research. This article begins by offering a brief overview of some of the developments as a whole. It goes on to offer a detailed treatment of a series of geospatial statistical techniques which, it is hoped, may be applicable within a wide range of music and music education research fields. These techniques are illustrated through references to a deviant idiographic case study dealing with instrumental tuition provided by one English local government area (local authority) between 2003 and 2010. The case study draws on analyses of detailed anonymized participant records (n = 6063) using, amongst other techniques, location quotients, tests for spatial autocorrelation and distinct distributions and ‘global’ and ‘local’ regression models. The article will demonstrate how these techniques can be applied using open-source software and freely available census, government and cartographic data.
Technical exercise practice: Can piano students be motivated through gamification?
Authors: Birch Heather J. S. , Woodruff Earl 
Published: July 2017

Abstract
Gamification is a process whereby game design and game mechanics are applied in non-game contexts to influence behaviour. This research study explores the effects of gamification on young piano students’ practice of technical elements such as scales, chords and arpeggios in the context of independent practice between private lessons. A control and a treatment group of ten piano students each were formed across two different private piano studios. A game-like environment was introduced for the treatment group, in which the players experienced game elements such as avatars and rewards, including points, badges and level achievements. Gamification was found to have a positive effect on the number of technical elements students mastered and a modest effect on their attitude towards practicing technical elements. The educational implications for these findings are discussed.
Assessing the suitability of Kinect for measuring the impact of a week-long Feldenkrais method workshop on pianists’ posture and movement
Authors: Beacon Jillian F. , Comeau Gilles , Payeur Pierre , Russell Donald 
Published: July 2017

Abstract
The Microsoft Kinect depth sensor could offer a convenient, markerless solution for quantifying the head and torso movements of pianists to examine the impact of somatic training on playing postures and movement. To assess the suitability of the Kinect for this application, we tracked four professional piano teachers performing scales immediately before and after a week-long workshop involving daily Feldenkrais Awareness through Movement (ATM) lessons. We compared Kinect skeletal tracking data with 2D reference data obtained simultaneously using Dartfish video analysis software. Analysis revealed frequent tracking errors in the Kinect data compared to reference data from Dartfish. Differences in pre- and post-test measurements of forward head position, head height, C7 vertebra height and shoulder displacement did not correspond between Dartfish and Kinect. Our results suggest that one Kinect sensor does not provide enough accuracy to track torso movements of pianists for the purposes of ergonomic assessment in response to somatic training.
A new medium for remote music tuition
Authors: Duffy Sam , Healey Patrick 
Published: July 2017

Abstract
It is common to learn to play an orchestral musical instrument through regular one-to-one lessons with an experienced musician as a tutor. Students may work with the same tutor for many years, meeting regularly to receive real-time, iterative feedback on their performance. However, musicians travel regularly to audition, teach and perform and this can sometimes make it difficult to maintain regular contact. In addition, an experienced tutor for a specific instrument or musical style may not be available locally. General instrumental tuition may not be available at all in geographically distributed communities. One solution is to use technology such as videoconference to facilitate a remote lesson; however, this fundamentally changes the teaching interaction. For example, as a result of the change in communication medium, the availability of non-verbal cues and perception of relative spatiality is reduced. We describe a study using video-ethnography, qualitative video analysis and conversation analysis to make a fine-grained examination of student–tutor interaction during five co-present and one video-mediated woodwind lesson. Our findings are used to propose an alternative technological solution – an interactive digital score. Rather than the face-to-face configuration enforced by videoconference, interacting through a shared digital score, augmented by visual representation of the social cues found to be commonly used in co-present lessons, will better support naturalistic student–tutor interaction during the remote lesson experience. Our findings may also be applicable to other fields where knowledge and practice of a physical skill sometimes need to be taught remotely, such as surgery or dentistry.
Ubiquitous music research: Everyday musical phenomena and their multidisciplinary implications for creativity and education
Authors: De Lima Maria Helena , Keller Damián , Flores Luciano Vargas , Ferreira Edemilson 
Published: July 2017

Abstract
This article presents contributions from the emerging and multidisciplinary research field of Ubiquitous Music (Ubimus) for creative studies and educational practices. Ubimus research focuses on music making in everyday settings, employing creativity-centred design strategies to support creative experiences within artistic and educational endeavours. We report two studies which address the challenges in the design of a creativity support metaphor – time tagging – and that target the application of ecologically grounded creative strategies within formal educational processes as a way to increase social interactions among musicians and laypeople in everyday settings. The first one constitutes a longitudinal planning study featuring group collaborations within the context of educational research activities done by teenagers in a public high school. The second study features several improvisatory sessions by casual participants and musicians at a non-standard venue. We discuss qualitative and quantitative assessments conducted with the teenage students of the first study and with the adult-volunteers of the second study.

The study also included the analysis of the different versions of the songs and their evolution, the participants’ individual contributions to an online private diary and their interactions within a customized designed online platform. Results showed a clear impact on participants in different areas: development of social and emotional skills, ability to problem solving and work in teams, development of technological skills and clear improvements in the process of musical creation.
La incidencia del liderazgo y el clima escolar en la satisfacción laboral de los docentes en América Latina
Authors: Martínez-Garrido Cynthia 
Published: July 2017

La investigación sobre Eficacia Educativa ha identificado la Satisfacción laboral de los docentes como un elemento fundamental para que se desarrolle una enseñanza eficaz. Sin embargo, frente a la cantidad de estudios que analizan el efecto de la satisfacción laboral de los docentes en el rendimiento de los estudiantes, son menos las investigaciones que permiten conocer y comprender cómo se desarrolla la satisfacción de los docentes y de qué depende. El objetivo de esta investigación es conocer la relación entre la satisfacción laboral del docente, la dirección escolar y el clima. Para dar respuesta a este objetivo se realiza un análisis multinivel de la información aportada por los docentes de 5.733 escuelas de 15 países latinoamericanos que participan en el Tercer Estudio Regional Comparativo y Explicativo (TERCE) de la UNESCO. Nuestros resultados señalan que el ambiente laboral, el clima de aula, el apoyo de la dirección a los maestros son las variables que más impactan sobre el grado de satisfacción laboral de los docentes en Latinoamérica.
The Euler equation around the world
Authors: Stracca Livio 
Published: July 2017

AbstractThis paper discusses the empirical challenges associated with the estimation of the New Keynesian IS curve and provides an estimate of the forward looking IS curve by pooling macro data from 31 countries, delivering over 4000 observations on which to test the specification. The main finding of the paper is that it is possible to recover the theory-consistent IS curve from macro data when the sample size is large enough and the intrument is valid and strong. I also test the validity of the instruments by comparing estimates in countries which have or do not have an independent monetary policy reaction function. Another relevant finding is that the slope of the IS curve appears to have steepened over time since the 1990s, probably reflecting financial liberalisation.
Pass-through of imported input prices to domestic producer prices: evidence from sector-level data
Authors: Ahn JaeBin , Park Chang-Gui , Park Chanho 
Published: July 2017

AbstractMotivated by stylized facts pointing to a dominant role of imported inputs in transmitting external price shocks to domestic prices, this paper zooms in to study the pass-through of imported input costs to domestic producer prices. Our approach constructs effective input price indices from sector-level price data combined with sector-level information on input-output linkages. Applying an error correction model specification to sector-level output and input prices, the long-run pass-through rate of effective imported input costs to domestic producer prices is estimated to be around 70 percent in Korea and almost 100 percent in selected European countries.
Democracy and income: taking parameter heterogeneity and cross-country dependency into account
Authors: Sequeira Tiago Neves 
Published: July 2017

AbstractThis paper investigates the relationship between income and democracy using common correlated effects (CCE) extended estimators which take into account the fact that democracy variables are highly correlated across countries and the possibility of heterogeneous effects of income on democracy in different countries. Using a wider database than ever, covering annual data from 1804 to 2010 for almost all countries, we show that overall, the effect of income on democracy is significantly negative when the time-series features of the data are taken into account, a result that comes from the low-income countries. This calls back into question the controversy about the empirical effect of income on democracy.
Has the forecasting performance of the Federal Reserve’s Greenbooks changed over time?
Authors: Ekşi Ozan , Orman Cüneyt , Taş Bedri Kamil Onur 
Published: July 2017

AbstractWe investigate how the forecasting performance of the Federal Reserve Greenbooks has changed relative to commercial forecasters between 1974 and 2009. To this end, we analyze time-variation in the Greenbook coefficients in forecast encompassing regressions. Assuming that model coefficients change continuously, we estimate unobserved components models using Bayesian inference techniques. To verify that our results do not depend on the specific way change is modeled, we also allow the coefficients to change discretely rather than continuously and test for structural breaks using classical inference techniques. We find that the Greenbook forecasts have been consistently superior to the commercial forecasts at all horizons throughout our sample period. Although the forecasting performance gap has narrowed at more distant horizons after the early-to-mid 1980s, it remains significant.
Effect of organoclay on structure, morphology, thermal behavior and coating performance of Jatropha oil based polyesteramide
Authors: Alam Manawwer , Sharmin Eram , Alandis Naser M. , Ahmad Naushad 
Published: July 2017

AbstractJatropha oil (JO) is an inedible oil mainly used in biodiesel. We have attempted to prepare a JO-based polyesteramide/clay composite using a one-pot, two-step reaction, for application as a protective coating. The aim of the work is to utilize JO for its value-added application by preparing a JO polyesteramide/clay composite, to investigate the potential of the prepared composite as a protective coating, and also to study the effect of loaded clay on the structure, morphology, thermal stability and coating properties of the composite. The formation of composites was confirmed by Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM) and atomic force microscope (AFM) studies. The coating properties were studied by standard physico-mechanical and corrosion resistance tests in corrosive media (3.5 wt% HCl, 3.5 wt% NaCl and tap water). The thermal stability was assessed by differential scanning calorimetry (DSC), thermogravimetric (TGA) and derivative thermogravimetric (DTG) analyses. The coatings showed good physico-mechanical and corrosion resistance performance and can be safely used up to 275°C. The approach paves way towards an alternate value addition to a non-edible oil.
Out of Step and Out of Touch: The Matter with Kansas in the 2014 Midterm Election
Authors: McKee Seth C. , Ostrander Ian , Hood M. V. 
Published: July 2017

Abstract
In recent years the politics of Kansas, with its strong historic ties to the Republican Party, have taken a hard right turn. This political environment mirrors many other states in which one political party effectively dominates the policymaking process. But while political dominance may aid incumbency it can also contribute to the kinds of political excess that tend to promote electoral backlashes. In this paper, we use a survey of likely Kansas voters during the 2014 midterm elections to examine opinions and voting preferences related to two state-wide races in which incumbent overreach played a prominent role. In particular, we examine the reelection campaigns of Governor Brownback, as his remarkably austere and highly unpopular budget left him ideologically out of step with most voters, and Senator Roberts, as his lack of residence in the state after years of serving in the Senate left him out of touch with a disgruntled electorate. Although both Republicans survived reelection, their actions ensured an unusually competitive midterm in an otherwise deep red state.

Authors: Xu X. P. , Liu Q. M. , Xia C. Z. , Zou J. S. 
Published: July 2017

AbstractSi3N4 ceramics and 304 stainless steel were joined by the Cu/Ag-Cu/Ti laminated filler metal. Interfacial microstructure of brazed joint and effect of brazing temperature and thickness of Cu foil on mechanical properties were studied in this paper. Research results showed that the interfacial microstructure of the brazed joint might be 304 stainless steel/TiFe2/Ag-Cu eutectic+Cu(s,s)/Cu(s,s)/Cu(s,s)+Ag-Cu eutectic/Cu3Ti+TiN/Si3N4 ceramics. With the increasing of the brazing temperature, four-point bending strength of the brazed joint initially increased, then decreased. The bending strength reached the maximum value of 53 MPa at 1153 K when the thickness of Cu foil was 500 μm. The bending strength reached the maximum value of 57 MPa with 1 mm thickness Cu interlayer under the brazing temperature of 1153 K.

Published: July 2017

AbstractTo make use of chromium slag waste, this study examined the technology of the preparation of MgAl2O4 spinel refractory raw material by using chromium slag. The results showed that (1) using the traditional sintering process of synthetic spinel, the highest volume density was 3.14 g/cm3 and the lowest porosity rate was 9.16 %. With the increase of the proportion of MgO powder mixing, bulk density and porosity fluctuations, and which cannot meet the requirements of refractory raw materials. (2) For MgAl2O4 spinel prepared by the electric-melting process, the highest volume density was 3.27 g/cm3 and the lowest porosity rate was 8.78 %. Volume density and the porosity remained stable, and they are affected by MgO powder thus the blending ratio is very small, which can satisfy the requirements of refractory raw materials. (3) MgAl2O4 spinel prepared by the electric-melting method is superior to traditional MgAl2O4 spinel in terms of slag resistance and thermal shock resistance.
