El sociograma como instrumento de evaluación del clima de aula

La comprensión y el estudio de las relaciones entre el alumnado en las aulas es fundamental, tanto para lograr una satisfactoria convivencia escolar como para evitar la violencia, el acoso escolar o bullying. Por ello es conveniente conocer la estructura informal de los alumnos dentro de la clase, identificando los grupos que se forman y sus dinámicas de exclusión y liderazgo. Para poder intervenir en un grupo social, el educador debe conocer a fondo las relaciones sociales que en él fluyen. En esta investigación, se describen las relaciones que hay en una clase de 6º de primaria del colegio Cardenal Ilundain, mostrando los diferentes grupos y subgrupos que existen en el aula y señalando qué sujetos ejercen el rol de líder y cuáles son rechazados. Para ello se ha elaborado un test sociométrico que nos permite conocer las relaciones, jerárquicas o no, del grupo-clase y realizar una serie de sociogramas que proporcionan una visión de las relaciones entre compañeros y muestran tanto el nivel de integración de cada alumno/a como los contextos en los que se relacionan. En el diseño del sociograma se han tenido en cuenta los resultados de algunas investigaciones sobre este tema, principalmente las investigaciones de Jacob Levy Moreno creador del sociograma

Application of gold complexes in the development of sensors for volatile organic compounds

Two different kinds of sensors have been developed by using the same kind of vapochromic complexes. The vapochromic materials [Au2Ag2(C6F5)(4)L-2](n) have different colours depending on the ligand L. These materials change, reversibly, their optical properties, colour and fluorescence, in the presence of the vapours of volatile organic compounds (VOCs). For practical applications, two different ways of fixing the vapochromic material to the optical fibre have been used: the sol-gel technique and the electrostatic self-assembly method (ESA). With the first technique the sensors can even be used to detect VOCs in aqueous solutions, and using the second method it has been possible to develop nanosensors.

Replicación Activa en NodeJS con 0MQ

Mi trabajo final de grado se centra en el aprendizaje, desarrollo y divulgación del entorno de programación NodeJS, un entorno orientado a eventos que está basado en el lenguaje de programación JavaScript en el lado del servidor. El enfoque de NodeJS es el desarrollo de aplicaciones de red altamente escalables. La escalabilidad se proporciona por la eficiencia obtenida a lo largo de los años en la optimización de código en los motores de JavaScript por la delegación asíncrona a tareas propias del sistema operativo. Aprovechando estas cualidades, desarrollo la implementación de un algoritmo basado en el modelo de replicación activa consistente en mantener copias de objetos de datos en distintos almacenes de datos. Con este modelo se constituye un sistema distribuido tolerante a fallos y de alta disponibilidad. Para los protocolos de comunicación se utilizan de los socket 0MQ y se desarrollan algunos ejemplos del uso de cada tipo de ellos.

Measurement of the differential cross section for the reaction gamman-->pi- p from deuterium.

We report a measurement of the differential cross section for the gamman-->pi- p process from the CLAS detector at Jefferson Laboratory in Hall B for photon energies between 1.0 and 3.5 GeV and pion center-of-mass (c.m.) angles (thetac.m.) between 50 degrees and 115 degrees. We confirm a previous indication of a broad enhancement around a c.m. energy ([sqrt]s) of 2.1 GeV at thetac.m.=90 degrees in the scaled differential cross section s7dsigma/dt and a rapid falloff in a center-of-mass energy region of about 400 MeV following the enhancement. Our data show an angular dependence of this enhancement as the suggested scaling region is approached for thetac.m. from 70 degrees to 105 degrees.

Breech delivery and birth‐related behaviors in wild mantled howling monkeys

The breech birth of an infant mantled howling monkey was observed on February 12, 1990. The mother assisted the successful delivery by pulling on the infant's tail and hindleg. No other members of the social group attended the mother or demonstrated any interest in the birth process. Copyright © 1991 Wiley‐Liss, Inc., A Wiley Company

Smartphone ECG for evaluation of STEMI: Results of the ST LEUIS Pilot Study

© 2015 Elsevier Inc. All rights reserved.Background 12-lead ECG is a critical component of initial evaluation of cardiac ischemia, but has traditionally been limited to large, dedicated equipment in medical care environments. Smartphones provide a potential alternative platform for the extension of ECG to new care settings and to improve timeliness of care. Objective To gain experience with smartphone electrocardiography prior to designing a larger multicenter study evaluating standard 12-lead ECG compared to smartphone ECG. Methods 6 patients for whom the hospital STEMI protocol was activated were evaluated with traditional 12-lead ECG followed immediately by a smartphone ECG using right (VnR) and left (VnL) limb leads for precordial grounding. The AliveCor™ Heart Monitor was utilized for this study. All tracings were taken prior to catheterization or immediately after revascularization while still in the catheterization laboratory. Results The smartphone ECG had excellent correlation with the gold standard 12-lead ECG in all patients. Four out of six tracings were judged to meet STEMI criteria on both modalities as determined by three experienced cardiologists, and in the remaining two, consensus indicated a non-STEMI ECG diagnosis. No significant difference was noted between VnR and VnL. Conclusions Smartphone based electrocardiography is a promising, developing technology intended to increase availability and speed of electrocardiographic evaluation. This study confirmed the potential of a smartphone ECG for evaluation of acute ischemia and the feasibility of studying this technology further to define the diagnostic accuracy, limitations and appropriate use of this new technology.

Operationalizing the social-ecological systems framework to assess sustainability.

Environmental governance is more effective when the scales of ecological processes are well matched with the human institutions charged with managing human-environment interactions. The social-ecological systems (SESs) framework provides guidance on how to assess the social and ecological dimensions that contribute to sustainable resource use and management, but rarely if ever has been operationalized for multiple localities in a spatially explicit, quantitative manner. Here, we use the case of small-scale fisheries in Baja California Sur, Mexico, to identify distinct SES regions and test key aspects of coupled SESs theory. Regions that exhibit greater potential for social-ecological sustainability in one dimension do not necessarily exhibit it in others, highlighting the importance of integrative, coupled system analyses when implementing spatial planning and other ecosystem-based strategies.

Science objectives and performances of NOMAD, a spectrometer suite for the ExoMars TGO mission

The NOMAD spectrometer suite on the ExoMars Trace Gas Orbiter will map the composition and distribution of Mars atmospheric trace species in unprecedented detail, fulfilling many of the scientific objectives of the joint ESA-Roscosmos ExoMars Trace Gas Orbiter mission. The instrument is a combination of three channels, covering a spectral range from the UV to the IR, and can perform solar occultation, nadir and limb observations. In this paper, we present the science objectives of the instrument and how these objectives have influenced the design of the channels. We also discuss the expected performance of the instrument in terms of coverage and detection sensitivity.
