Authors: Espada Largo Manuel , Lorenzo-Llamas Elena María , Torrego Seijo Juan Carlos 
Published: May 2017

Los problemas de comportamiento en centros educativos son objeto de numerosas investigaciones (Mayorga y Oliver, 2006; Olweus, 1973a; Sela-Shayovitz, 2009; Sellman, 2011; Torrego y Galán, 2008). El objetivo de este estudio es describir cómo se interviene con alumnado con Alteraciones Graves de Conducta (AGC) en los Institutos públicos de la provincia de Toledo (España). El plan de investigación corresponde a un estudio de caso único de tipo intrínseco. Las técnicas de recogida y análisis de datos son cuantitativas vs cualitativas complementariamente. Se diseñaron categorías de análisis prefiguradas a partir del marco teórico del estudio y se recogieron categorías emergentes. El instrumento utilizado fue un cuestionario de entrevista semiestructurada diseñado ad hoc. Los resultados indicaron que la intervención que se está desarrollando en los Institutos públicos de la provincia de Toledo con este tipo de alumnado debería ser revisada. Existen diferencias importantes entre los criterios básicos de prevención, la atención desde un planteamiento integral de mejora de la convivencia y el nivel de aplicación real en los centros. Se concluyen propuestas de mejora.
L’art comme remise en scène de la vie quotidienne : traduire le social en esthétique
Authors: Bui Camille 
Published: May 2017

Cet article explore, à travers le paradigme de la traduction, la mise en scène des interactions sociales dans Playtime de Jacques Tati (1967), Kontakthof de Pina Bausch (1978-2000-2008) et Reconstitutions d’Édouard Levé (1998-2003). Chacune de ces oeuvres témoigne du désir de traduire le social en esthétique : il s’agit de dire l’ordinaire des jeux de distance et de proximité entre les corps, par le cinéma, la danse ou la photographie. Ce geste de traduction emprunte à la logique de la re-présentation qui réifie le social, mais il ne peut s’y réduire. Car la traduction vise aussi à reconduire, sur la scène de l’art, la dynamique du lien en tant qu’adresse faite à l’autre, au risque de son échec. Penser le geste artistique comme traduction permet d’être sensible au devenir chorégraphique des situations sociales, autant qu’à la socialité qui anime des oeuvres qui nous émeuvent ou nous indiffèrent.
Measuring, monitoring, and managing for productive learning? Australian insights into the enumeration of education
Authors: Hardy Ian 
Published: May 2017

This article reflects upon how teacher learning is currently construed under conditions of increased measurement of student learning outcomes, and the effects of advocacy for such enumeration processes. It draws upon a broad range of literature on the practice of education, measuring learning, and its effects on teachers’ learning. To help ground the analysis, the paper analyses the meeting transcripts of an ongoing, long-term teacher learning initiative in a school in northern Queensland, Australia, and how processes of measurement influenced such learning. These reflections reveal teachers’ practices as deeply influenced by the ways in which schooling is construed under conditions of increased pressure to enumerate learning, even as this is contested. Processes of ‘measuring learning’ are revealed as enabling practices of ‘monitoring learning’ through students’ data profiles, and ultimately, of ‘managing learning’, particularly of lower performing students. The article cautions that while these resultant practices of ‘managing’ learning may be productive of teacher learning for substantive student learning, the extent to which this is the case under conditions of more fine-grained processes of measuring and monitoring of student learning is a contested point, and requiring much more careful analysis than currently attends support for the enumeration of education more broadly.
Emergency Health Care Professionals’ Understanding of the Costs of Care in the Emergency Department
Authors: Hoffman Kevin A. , Mancini Michelino 
Published: May 2017

Abstract

Background
Efficiency and fiscal responsibility are important to the equal, safe, and effective delivery of care in the emergency department, where all presenting patients must be evaluated for emergent conditions. Health care professionals’ understanding of the costs of care is a first step to developing rational approaches for the efficient distribution of the finite resources hospitals and emergency departments have at their disposal to reduce costs to patients and health care systems.

Objective
To determine emergency department health care professionals’ knowledge of the costs to patients of routine care delivered in the emergency department.

Methods
An internet-based survey of currently practicing emergency medicine health care professionals with various levels of training (physicians, residents, physician assistants, and nurse practitioners) was conducted to evaluate their ability to identify the cost of care for 3 common presentations to the emergency department: abdominal pain, dyspnea, and sore throat.

Results
Four hundred forty-one emergency medicine health care professionals participated. In the 3 cases presented, correct costs were determined by 43.0%, 32.0%, and 40.1% of participants, respectively. Geographic region was not related to cost determination. Larger institution size was related to greater cost chosen (P=.01). Higher level of training was significantly correlated with perceived understanding of cost (P<.001); however, it was not related to accurate cost assessment in this study.

Conclusion
Emergency medicine health care professionals have an inadequate understanding of the costs associated with care routinely provided in the emergency department.
Bridging the Gap: An Osteopathic Primary Care–Centered Approach to Duchenne Muscular Dystrophy
Authors: Carls Christopher , Krajacic Predrag 
Published: May 2017

Abstract
Duchenne muscular dystrophy (DMD) is a deadly and incurable disease typically diagnosed in early childhood. Presently, the delay between a caregiver's initial concern and the primary care physician obtaining creatine kinase levels—the most important screening test—is more than a year. It is imperative to diagnose DMD as soon as possible because early treatment has the potential to double the patient's lifespan. In addition, because of geographic and economic disadvantages, multidisciplinary DMD treatment centers are not readily available to all patients. Therefore, the challenge of early diagnosis and treatment coordination rests with the primary care physician. The present review provides osteopathic primary care physicians with current and relevant information regarding DMD diagnosis and management.
High or low? Comparing high and low-variability phonetic training in adult and child second language learners
Authors: Giannakopoulou Anastasia , Brown Helen , Clayards Meghan , Wonnacott Elizabeth 
Published: May 2017

BackgroundHigh talker variability (i.e., multiple voices in the input) has been found effective in training nonnative phonetic contrasts in adults. A small number of studies suggest that children also benefit from high-variability phonetic training with some evidence that they show greater learning (more plasticity) than adults given matched input, although results are mixed. However, no study has directly compared the effectiveness of high versus low talker variability in children.MethodsNative Greek-speaking eight-year-olds (N= 52), and adults (N= 41) were exposed to the English /i/-/ɪ/ contrast in 10 training sessions through a computerized word-learning game. Pre- and post-training tests examined discrimination of the contrast as well as lexical learning. Participants were randomly assigned to high (four talkers) or low (one talker) variability training conditions.ResultsBoth age groups improved during training, and both improved more while trained with a single talker. Results of a three-interval oddity discrimination test did not show the predicted benefit of high-variability training in either age group. Instead, children showed an effect in thereversedirection—i.e., reliably greater improvements in discrimination following single talker training, even for untrained generalization items, although the result is qualified by (accidental) differences between participant groups at pre-test. Adults showed a numeric advantage for high-variability but were inconsistent with respect to voice and word novelty. In addition, no effect of variability was found for lexical learning. There was no evidence of greater plasticity for phonetic learning in child learners.DiscussionThis paper adds to the handful of studies demonstrating that, like adults, child learners can improve their discrimination of a phonetic contrast via computerized training. There was no evidence of a benefit of training with multiple talkers, either for discrimination or word learning. The results also do not support the findings of greater plasticity in child learners found in a previous paper (Giannakopoulou, Uther & Ylinen, 2013a). We discuss these results in terms of various differences between training and test tasks used in the current work compared with previous literature.
A new view on the morphology and phylogeny of eugregarines suggested by the evidence from the gregarineAncora sagittata(Leuckart, 1860) Labbé, 1899 (Apicomplexa: Eugregarinida)

Published: May 2017

BackgroundGregarines are a group of early branching Apicomplexa parasitizing invertebrate animals. Despite their wide distribution and relevance to the understanding the phylogenesis of apicomplexans, gregarines remain understudied: light microscopy data are insufficient for classification, and electron microscopy and molecular data are fragmentary and overlap only partially.MethodsScanning and transmission electron microscopy, PCR, DNA cloning and sequencing (Sanger and NGS), molecular phylogenetic analyses using ribosomal RNA genes (18S (SSU), 5.8S, and 28S (LSU) ribosomal DNAs (rDNAs)).Results and DiscussionWe present the results of an ultrastructural and molecular phylogenetic study on the marine gregarineAncora sagittatafrom the polychaeteCapitella capitatafollowed by evolutionary and taxonomic synthesis of the morphological and molecular phylogenetic evidence on eugregarines. The ultrastructure ofAncora sagittatagenerally corresponds to that of other eugregarines, but reveals some differences in epicytic folds (crests) and attachment apparatus to gregarines in the family Lecudinidae, whereAncora sagittatahas been classified. Molecular phylogenetic trees based on SSU (18S) rDNA reveal several robust clades (superfamilies) of eugregarines, including Ancoroidea superfam. nov., which comprises two families (Ancoridae fam. nov. and Polyplicariidae) and branches separately from the Lecudinidae; thus, all representatives of Ancoroidea are here officially removed from the Lecudinidae. Analysis of sequence data also points to possible cryptic species withinAncora sagittataand the inclusion of numerous environmental sequences from anoxic habitats within the Ancoroidea. LSU (28S) rDNA phylogenies, unlike the analysis of SSU rDNA alone, recover a well-supported monophyly of the gregarines involved (eugregarines), although this conclusion is currently limited by sparse taxon sampling and the presence of fast-evolving sequences in some species. Comparative morphological analyses of gregarine teguments and attachment organelles lead us to revise their terminology. The terms “longitudinal folds” and “mucron” are restricted to archigregarines, whereas the terms “epicystic crests” and “epimerite” are proposed to describe the candidate synapomorphies of eugregarines, which, consequently, are considered as a monophyletic group. Abolishing the suborders Aseptata and Septata, incorporating neogregarines into the Eugregarinida, and treating the major molecular phylogenetic lineages of eugregarines as superfamilies appear as the best way of reconciling recent morphological and molecular evidence. Accordingly, the diagnosis of the order Eugregarinida Léger, 1900 is updated.
Clinical impact of human papillomavirus in laryngeal squamous cell carcinoma: a retrospective study

Published: May 2017

Objectives
The purpose of this study is to determine the prevalence and clinical impact of human papillomavirus (HPV) related laryngeal squamous cell carcinoma (LSCC).

Methods
A total of 106 LSCC patients who underwent primary surgical resection with or without adjuvant radiotherapy/chemoradiotherapy were enrolled retrospectively. Tumors collected from paraffin-embedded samples were used for HPV detection by polymerase chain reaction and in situ hybridization technique. Clinicopathological parameters were recorded for analysis.

Results
The prevalence of HPV in patients with LSCC was 13.2% in our series and 12 out of 14 (85.7%) HPV-positive tumors were HPV-16. The patients with HPV-positive tumors were older (p = 0.042), less local/regional recurrence (p = 0.037) and non-smoker (p = 0.068). There was no significant difference in the 5-year overall survival (OS) (p = 0.8056) between HPV-positive and -negative tumors. The patients with HPV-positive tumors had a better 5-year disease-specific survival (DSS) (100% vs. 84.8%, p = 0.1485), although the difference did not reach statistical significance. However, the local/regional control rate was significantly better in HPV-positive tumors than in HPV-negative tumors (100% vs. 75%, p = 0.0494).

Conclusions
A low prevalence of HPV infection in our series suggests that HPV is not a major cause of LSCC. However, a 100% local/regional control rate and DSS were observed in HPV-positive tumors. This finding suggests a different tumor behavior between HPV-positive and HPV-negative LSCC. Further research with a larger sample size is necessary to confirm our observations.

AbstractUsing a combined approach of seafloor mapping, MAPR and CTD survey, we report evidence for active hydrothermal venting along the 130°‐140°E section of the poorly‐known South‐East Indian Ridge (SEIR) from the Australia‐Antarctic Discordance (AAD) to the George V Fracture Zone (FZ). Along the latter, we report Eh and CH4 anomalies in the water column above a serpentinite massif, which unambiguously testify for ultramafic‐related fluid flow. This is the first time that such circulation is observed on an intermediate‐spreading ridge. The ridge axis itself is characterized by numerous off‐axis volcanoes, suggesting a high magma supply. The water column survey indicates the presence of at least ten distinct hydrothermal plumes along the axis. The CH4:Mn ratios of the plumes vary from 0.37 to 0.65 denoting different underlying processes, from typical basalt‐hosted to ultramafic‐hosted high‐temperature hydrothermal circulation. Our data suggest that the change of mantle temperature along the SEIR not only regulates the magma supply, but also the hydrothermal activity. The distribution of hydrothermal plumes from a ridge segment to another implies secondary controls such as the presence of fractures and faults along the axis or in the axial discontinuities. We conclude from these results that hydrothermal activity along the SEIR is controlled by magmatic processes at the regional scale and by the tectonics at the segment scale, which influences the type of hydrothermal circulation and leads to various chemical compositions. Such variety may impact global biogeochemical cycles, especially in the Southern Ocean where hydrothermal venting might be the only source of nutrients.

Published: May 2017

AbstractU‐Pb dating of calcite is an emerging but rapidly growing field of application in geochronology with great potential to inform problems in landscape, basin, and mountain belt evolution, through age determination of diagenetic cements, vein mineralization, and geological formations difficult to date otherwise. In this brief, we present isotope dilution U‐Pb isotope measurements on a sample of calcite (WC‐1) that has been and will continue to be used as a reference material for in situ U‐Pb Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA‐ICP‐MS) dating, and which is suitable to be distributed to the geochronological community. We present in situ measurements using LA‐ICP‐MS to demonstrate the suitability of WC‐1 for use as a U‐Pb dating reference material, in spite of it not being isotopically homogeneous. The WC‐1 calcite sample is 254.4 ± 6.4 Ma old and comprised 85–98% radiogenic lead. It presents a suitable reference material that can facilitate dating of calcite ranging in age from Precambrian to late Neogene age.
New insights into the magmatism in the northern margin of the South China Sea: Spatial features and volume of intraplate seamounts

Published: May 2017

AbstractThe extensive intraplate seamounts are obvious features in the northern South China Sea (SCS). However, the distribution, volume, and origin of these seamounts are not well understood, which greatly hinders our understanding of magmatism in the SCS. Based on high‐resolution bathymetric data and 147 seismic profiles, and combining gravity and magnetic data, we first identify 45 seamounts in the northern margin of the SCS and simulate their shape with elliptical cones. Results show that the total volume of these 45 seamounts above seafloor is estimated at about 1885–3078 km3 and the total volume of intrusive magma above Moho is about 0.15 Mkm3, which is close to the estimates for classic large igneous provinces across the world. These seamounts are mostly located on the continental slope with thin crust (approximately 12–18 km), which reduces the overlying pressure and shortens the magmatic conduits. The dominant azimuth of elliptical major axis in seamounts is consistent with the synrift and synspreading fault strikes (NE‐NEE), indicating that these preexisting faults provide magmatic conduits for the subsequent postrift intraplate seamounts. Based on three existing clues, i.e., (1) the intraplate seamounts, high velocity layer and Hainan mantle plume are contiguous in 3‐D space, (2) the high‐velocity layer is thicker beneath the continental shelf but thinner beneath the slope, and (3) the basalts dredged from certain seamounts show OIB‐type geochemical features, we propose a magmatic upwelling pattern which contains Hainan mantle plume to explain the spatial and morphological characteristics of these intraplate seamounts.
Calculation of in situ acoustic sediment attenuation using off‐the‐shelf horizontal ADCPs in low concentration settings
Authors: Haught Dan , Venditti Jeremy G. , Wright Scott A. 
Published: May 2017

AbstractThe use of “off‐the‐shelf” acoustic Doppler velocity profilers (ADCPs) to estimate suspended sediment concentration and grain‐size in rivers requires robust methods to estimate sound attenuation by suspended sediment. Theoretical estimates of sediment attenuation require a priori knowledge of the concentration and grain‐size distribution (GSD), making the method impractical to apply in routine monitoring programs. In situ methods use acoustic backscatter profile slope to estimate sediment attenuation, and are a more attractive option. However, the performance of in situ sediment attenuation methods has not been extensively compared to theoretical methods. We used three collocated horizontally mounted ADCPs in the Fraser River at Mission, British Columbia and 298 observations of concentration and GSD along the acoustic beams to calculate theoretical and in situ sediment attenuation. Conversion of acoustic intensity from counts to decibels is influenced by the instrument noise floor, which affects the backscatter profile shape and therefore in situ attenuation. We develop a method that converts counts to decibels to maximize profile length, which is useful in rivers where cross‐channel acoustic profile penetration is a fraction of total channel width. Nevertheless, the agreement between theoretical and in situ attenuation is poor at low concentrations because cross‐stream gradients in concentration, sediment size or GSD can develop, which affect the backscatter profiles. We establish threshold concentrations below which in situ attenuation is unreliable in Fraser River. Our results call for careful examination of cross‐stream changes in suspended sediment characteristics and acoustic profiles across a range of flows before in situ attenuation methods are applied in river monitoring programs.
What happens to in‐soil Radon activity during a long‐lasting eruption? Insights from Etna by multidisciplinary data analysis

Published: May 2017

AbstractWe analyze short‐ to long‐term changes (from days to months) in Radon (Rn) activity measured nearby (<2 km) the eruptive fractures that fed a lava effusion at Mt. Etna, Italy, between 13 May 2008 and 6 July 2009. The N120‐140°E eruptive fractures opened between 3050 and 2620 m above sea level before a dike‐forming intrusion fed the ∼14 month‐long lava emission. Our high‐rate data streams include: Rn, ambient parameters (barometric pressure and soil temperature), and seismic data (earthquakes and volcanic tremor) recorded from January 2008 to July 2009. The analysis highlights repeated episodes of rock‐fracturing related to seismic swarms, and vigorous gas pulses and peak values in Rn emissions (maximum ∼4.1×105 Bq/m3 on 16 November 2008), which we interpreted in a conceptual model as the response to inputs from the magmatic system during the eruption. This multidisciplinary study: (i) provides evidence of a close relationship between Rn emission at a fumarole near the summit active craters and local earthquakes, and (ii) enables exploring the important role of the volcanic source on the temporal development of the Rn flux, which may account for the much higher (≫94 m/d) ascent speed of the Rn carrier (vapor) than diffusion. The close location of Rn probes to the active conduits, along with the application of our multidisciplinary approach, may shed new light on the internal dynamics of other active volcanoes worldwide.
