Cuestionario breve de respuesta parental ante el comportamiento disruptivo (RPCD): Perspectiva de los padres.
Authors: Cantero-García María , Alonso-Tapia Jesús 
Published: July 2017

<p>The aim of this study is to develop and validate the <em>questionnaire of parental response to </em><em>disruptive behavior (PRDB). </em> Parents can act proactively towards problems and their emotional repercussions, focusing on how to handle them positively, or can focus their attention on the emotional response generated by behavior problems, being overburdened by them. In order to assess the prevalent personal orientation to cope with disruption, to guide parents and to assess the effect of psychological interventions, a questionnaire such as the one proposed here is required. A total of 420 parents and their children participated in the study. The structural validity of the questionnaire was tested using confirmatory factor analysis first to compare a multifactorial model (five specific factors) with a multifactorial-hierarchical model (with two second-order factors), and second, to study the cross validity of both models. The predictive validity was tested analyzing the relationship between parents’ and children’ perceptions of family climate. Children’s perceptions were assessed with the "Questionnaire of Behavior Management Climate perceived by children." Results showed that both models had good and similar fit indices that were almost identical in the two subsamples. Besides, the correlation analysis showed that although in general the relationship between perceptions of parents and their children is in the expected direction, this does not always happen. </p>

<p>Fragile X Syndrome (FXS) and Down Syndrome (DS) read better than expected for their mental age. We have measured three basic reading skills (word recognition, phonological awareness, and reading comprehension), and two standard intellectual and verbal measures: the McCarthy Scales of Children’s Abilities and Peabody Picture Vocabulary Tests. The tests were applied to 16 adolescents classified as FXS (<em>M</em> = 14.74 years old, <em>SD</em> = 4.03) and 16 adolescents classified as DS (<em>M</em> = 15.59 years old, <em>SD</em> = 2.35). For comparison purposes, the reading tests were also applied to a typical develop group of 70 children aged between 4.8 and 7.0 years (<em>M</em> = 6.11, <em>SD</em> = 0.71). Children with DS and FXS exhibited verbal skills superior to their cognitive development, especially in the FXS group. In reading performance, FXS showed a reading level corresponding to 5/6 their age, and for SD 6/7 of the equivalent reading age, however, both groups exhibited a similar reading performance in the three reading skills measured, when nonverbal mental age was controlled.</p>
Transforming finnish higher education: institutional mergers and conflicting academic identities

Published: July 2017

<p style="margin: 0cm 0cm 10pt;"> </p><p class="RESUMENCURSIVA">As in many other European countries also Finnish higher education system has witnessed several reforms over the past decade many of which originate in efforts to make more competitive and affordable higher education system. The aim of this paper is to describe the changes and institutional mergers in particular that have taken place in Finnish higher education and explore what kind of academic identities are constructed amid changes in Finnish higher education. The paper shows that the mergers followed the objectives set by the Finnish Ministry of Education and Culture for the structural development of the higher education system and that the creation of a joint culture for merged institutions was important yet challenging. The paper also argues that due to these external changes in Finnish higher education there is a tendency to move from a traditional notion of an academic toward more hybrid and dynamic understanding of what it is being an academic in the 21st century.</p><p style="margin: 0cm 0cm 10pt;"><span style="line-height: 115%; font-family: 'Times New Roman','serif'; font-size: 12pt; mso-ansi-language: EN-US;" lang="EN-US"><br /></span></p>

<p class="western" lang="es-ES" align="justify"><span style="font-family: Arial, serif;"><span><span style="font-family: Arial, sans-serif;">Entre las misiones de la Fundación Integra está el acelerar el proceso de implantación de la Sociedad de la Información en la Región de Murcia, por lo que focaliza una gran parte de su actividad en la generación de múltiples recursos digitales. En el marco de esta línea de actuación se desarrolló en el año 2015 el videojuego de realidad virtual “El Misterio de la Encomienda de Ricote”. Se trata de un contenido interactivo al cual se juega mediante gafas Oculus Rift. Este videojuego está dirigido principalmente a escolares de Educación Secundaria, en concreto a estudiantes de 2.º ESO a 4.º ESO, tanto por el contenido a tratar como por las dinámicas de juego diseñadas. A pesar de que son ya bastante numerosas las propuestas educativas para introducir la historia a través de los videojuegos, en raras ocasiones se procede a una evaluación educativa del videojuego. Aunque en este caso la jugabilidad del producto se demostró bastante alta en diferentes ocasiones, se hacía necesaria una reflexión sobre las ventajas didácticas que este juego podía proporcionar. La evaluación consta de una primera fase de prepilotaje para la que se ha diseñado un primer cuestionario con siete ítems que permiten un análisis de tipo mixto, que ha sido aplicado a modo de prueba piloto en un centro de Educación Secundaria sobre una muestra de 14 individuos de 13-14 años. Gracias a este instrumento, se procura precisar cuáles de las pruebas que se desarrollan durante el juego son más eficaces para el aprendizaje. Así mismo, la evaluación se completa con un segundo instrumento que analiza el nivel de aceptación por parte de los jugadores así como su percepción sobre lo aprendido.</span> </span></span></p>

Published: July 2017

<p>Manicures, pedicures, podólogos e clientes podem estar expostos ao risco de contaminação por diversas doenças transmitidas por materiais não esterilizados. O objetivo deste trabalho foi realizar um levantamento sobre os métodos de esterilização utilizados em salões de beleza de Salvador-BA. Foram aplicados questionários a 149 profissionais em 121salões. Todos os estabelecimentos possuíam aparelhos para a esterilização. 36,2% dos salões utilizavam esterilizadores ou forninhos; 34,7%, estufas de ar quente, e autoclaves, 29,1%. Observou-se grande variação na temperatura e tempo utilizados. Alguns salões não tinham termômetro na estufa e o ciclo de esterilização era interrompido durante o processo. Os resultados mostraram que, apesar dos salões possuírem aparelhos para a esterilização, a maioria dos profissionais desconheciam seu funcionamento. A possibilidade da ocorrência de infecções cruzadas pela utilização de materiais não esterilizados salientou a necessidade de cursos de treinamento destinados a esse público.</p>

Published: July 2017

<p>A prototipagem rápida é uma tecnologia de fabricação aditiva onde um modelo tridimensional é construído pela deposição de sucessivas camadas de material. O objetivo deste trabalho foi realizar uma revisão de literatura sobre a aplicabilidade da prototipagem rápida em especialidades da odontologia. Realizou-se uma abordagem indutiva com técnica de documentação indireta. Os dados obtidos foram submetidos a uma análise descritiva. Ao término da revisão, foi possível verificar que o desenvolvimento do estágio virtual ocorre a partir de softwares de modulação sólida (Computer-aided Design - CAD) ou da aquisição da imagem por scanner 3D, tomografia computadorizada ou ressonância magnética. Os processos mais usualmente aplicados são a estereolitografia, a modelagem por deposição fundida, a sinterização seletiva a laser, a impressão tridimensional, a thermojet e a polyjet. Essa técnica é utilizada na cirurgia bucomaxilofacial para o planejamento virtual de procedimentos cirúrgicos e personalização de placas de reconstrução; na implantodontia para a fabricação de biomodelos e guias cirúrgicas; na ortodontia para o diagnóstico e tratamento de caninos maxilares impactados e colagem de bráquetes; na prótese sua utilização consiste na confecção de próteses metálicas totais, próteses metalocerâmicas, coroas cerâmicas, próteses totais e próteses orbitárias, faciais e do septo nasal; e na endodontia para a documentação de casos não usuais. Conclui-se que, o crescente desenvolvimento da radiologia e imaginologia, em associação com a engenharia de softwares e processos de prototipagem rápida, tem possibilitado a introdução de procedimentos com mais segurança em odontologia e sua simplificação do ponto de vista operacional.</p><p> </p>
On the divergence of potential and actual evapotranspiration trends: An assessment across alternate global datasets
Authors: Anabalón Alfonso , Sharma Ashish 
Published: July 2017

AbstractEvapotranspiration is a key variable in hydrology, playing an important role in water and energy balance of the land surface. There has been speculation on the direction of trend in potential and actual evapotranspiration (PET and AET) resulting from rising global temperatures, in both observational and derived records representing the historical climate. In this study, PET and AET trends of eight different global model datasets where analyzed over two time periods: from 2003 to 2012 (short term) and from 1980 to 2012 (multidecadal), to identify regions where the trends coincide or differ and to study the reasons behind these changes. The short‐term analysis showed considerable uncertainty exists on the detection and direction of significant trends on both PET and AET. There was little agreement among the datasets about the direction of the global trends. The multidecadal study showed much more consistent trends throughout the datasets, particularly in relation to positive significant PET trends. During this period, the global PET mean increased 0.091 mm month−1 yr−1, while the global AET rose at 0.045 mm month−1 yr−1. Much of the opposite PET/AET trends can be attributed to changes in the precipitation. Most of the regions which present these trends are water‐limited and present strong correlations between AET and precipitation trends. Some energy‐limited regions showed an increasing gap between PET and AET, suggesting the influence of additional variables controlling AET.
Where is the magnetic energy for the expansion phase of auroral substorms accumulated? 2. The main body, not the magnetotail
Authors: Akasofu Syun‐Ichi 
Published: July 2017

AbstractIt is suggested that the magnetosphere tries to stabilize itself by quickly unloading the magnetic energy accumulated within its main body, when the accumulated magnetic energy exceeds a limited amount, which can be identified as the energy for the expansion phase. It is this process which manifests as the impulsive expansion phase, during which auroral arcs advance well beyond the presubstorm latitude in the midnight sector. It was shown in the previous paper that the magnetotail does not have enough magnetic energy for a medium substorm (energy 5 × 1015 J; AE = 1000 nT). In this paper, it is shown that (1) the reason of the short lifetime (1–1.5 h) of the expansion phase is due to the fact that a limited amount of magnetic energy accumulated during the growth phase is dissipated in a period similar to the duration of the growth phase (1–1.5 h); the accumulation rate is similar to the dissipation rate during the expansion phase: (2) when the main body of the magnetosphere accumulates the magnetic energy, it is inflated; β (= (nkT/B2/8π)) even at XGSM = −6 RE becomes close to 1.0 for magnetic energy (2.9 × 1014 J) which is less than the amount consumed by a medium intensity substorm. (3) As a result, the plasma sheet current and thus the magnetosphere are expected to become unstable, unloading the accumulated excess magnetic energy and resulting in current reduction and deflation. (4) The resulting deflation can cause an earthward electric field of 5–50 mV/m, which can generate Bostrom's current system, which is mainly responsible in producing various phenomena of the expansion phase. (5) The large range of substorm intensity (AE = 100–2000 nT) is likely to be due to the location where the energy is accumulated; the closer is the distance to the Earth (XGSM between −10 RE and −4 RE), the more intense the substorm intensity is.
The origin of volatiles in the Earth's mantle
Authors: Hier‐Majumder Saswata , Hirschmann Marc M. 
Published: July 2017

AbstractThe Earth's deep interior contains significant reservoirs of volatiles such as H, C, and N. Due to the incompatible nature of these volatile species, it has been difficult to reconcile their storage in the residual mantle immediately following crystallization of the terrestrial magma ocean (MO). As the magma ocean freezes, it is commonly assumed that very small amounts of melt are retained in the residual mantle, limiting the trapped volatile concentration in the primordial mantle. In this article, we show that inefficient melt drainage out of the freezing front can retain large amounts of volatiles hosted in the trapped melt in the residual mantle while creating a thick early atmosphere. Using a two‐phase flow model, we demonstrate that compaction within the moving freezing front is inefficient over time scales characteristic of magma ocean solidification. We employ a scaling relation between the trapped melt fraction, the rate of compaction, and the rate of freezing in our magma ocean evolution model. For cosmochemically plausible fractions of volatiles delivered during the later stages of accretion, our calculations suggest that up to 77% of total H2O and 12% of CO2 could have been trapped in the mantle during magma ocean crystallization. The assumption of a constant trapped melt fraction underestimates the mass of volatiles in the residual mantle by more than an order of magnitude.
Uranium isotope evidence for an expansion of marine anoxia during the end‐Triassic extinction

Published: July 2017

AbstractThe end‐Triassic extinction coincided with an increase in marine black shale deposition and biomarkers for photic zone euxinia, suggesting that anoxia played a role in suppressing marine biodiversity. However, global changes in ocean anoxia are difficult to quantify using proxies for local anoxia. Uranium isotopes (δ238U) in CaCO3 sediments deposited under locally well‐oxygenated bottom waters can passively track seawater δ238U, which is sensitive to the global areal extent of seafloor anoxia due to preferential reduction of 238U(VI) relative to 235U(VI) in anoxic marine sediments. We measured δ238U in shallow‐marine limestones from two stratigraphic sections in the Lombardy Basin, northern Italy, spanning over 400 m. We observe a ∼0.7‰ negative excursion in δ238U beginning in the lowermost Jurassic, coeval with the onset of the initial negative δ13C excursion and persisting for the duration of subsequent high δ13C values in the lower‐middle Hettangian stage. The δ238U excursion cannot be realistically explained by local mixing of uranium in primary marine carbonate and reduced authigenic uranium. Based on output from a forward model of the uranium cycle, the excursion is consistent with a 40–100‐fold increase in the extent of anoxic deposition occurring worldwide. Additionally, relatively constant uranium concentrations point toward increased uranium delivery to the oceans from continental weathering, which is consistent with weathering‐induced eutrophication following the rapid increase in pCO2 during emplacement of the Central Atlantic Magmatic Province. The relative timing and duration of the excursion in δ238U implies that anoxia could have delayed biotic recovery well into the Hettangian stage.
Ionospheric annual anomaly—New insights to the physical mechanisms
Authors: Sai Gowtam V. , Tulasi Ram S. 
Published: July 2017

AbstractThe ionospheric annual anomaly or nonseasonal anomaly of the ionosphere is characterized by globally increased ionization in December solstice than in June solstice. Though this phenomenon was reported several decades ago, the causal mechanisms have not been fully understood till today. In this paper, the F2 layer peak electron density (NmF2) data from Formosa satellite 3/Constellation Observing System for Meteorology, Ionosphere, and Climate‐radio occultation observations during the low solar activity year 2009 were systematically analyzed to investigate the physical mechanisms responsible for annual anomaly and its local time, latitudinal, and longitudinal variability. It is found that the annual anomaly is primarily dominant at Southern Hemisphere at all local times, with significant enhancements at equatorial ionization anomaly crest latitudes during noon to afternoon hours and at high latitudes during nighttimes. The annual anomaly in Northern Hemisphere occurs with relatively smaller magnitudes and confined only to morning to early afternoon hours (08–14 LT). This study brings out the important roles of effective neutral winds due to the geomagnetic field configuration and the offset between geomagnetic equator and subsolar point for the enhanced plasma density in the Southern Hemisphere during December that majorly contributes to the ionospheric annual anomaly. These results provide new insights to the responsible mechanisms behind the ionospheric annual anomaly and its local time latitudinal, and longitudinal variation
A corotation electric field model of the Earth derived from Swarm satellite magnetic field measurements
Authors: Maus Stefan 
Published: July 2017

AbstractRotation of the Earth in its own geomagnetic field sets up a primary corotation electric field, compensated by a secondary electric field of induced electrical charges. For the geomagnetic field measured by the Swarm constellation of satellites, a derivation of the global corotation electric field inside and outside of the corotation region is provided here, in both inertial and corotating reference frames. The Earth is assumed an electrical conductor, the lower atmosphere an insulator, followed by the corotating ionospheric E region again as a conductor. Outside of the Earth's core, the induced charge is immediately accessible from the spherical harmonic Gauss coefficients of the geomagnetic field. The charge density is positive at high northern and southern latitudes, negative at midlatitudes, and increases strongly toward the Earth's center. Small vertical electric fields of about 0.3 mV/m in the insulating atmospheric gap are caused by the corotation charges located in the ionosphere above and the Earth below. The corotation charges also flow outward into the region of closed magnetic field lines, forcing the plasmasphere to corotate. The electric field of the corotation charges further extends outside of the corotating regions, contributing radial outward electric fields of about 10 mV/m in the northern and southern polar caps. Depending on how the magnetosphere responds to these fields, the Earth may carry a net electric charge.
