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.

Floristic notes of Sierra del Rincón Biosphere Reserve (Spain, Madrid province)

New records of vascular plants from Sierra del Rincón Biosphere Reserve and surroundings (Spain, Madrid province) are provided. It is noteworthy the presence of atlantic flora in this continental area and the different shrubby communities in different sectors with different litology: in areas with gneiss they are dominated by leguminous genisteae; where it is schistous, shale or quartzite they are heathlands.

The emotional structure of the advertising message in radio

Radio advertising is suffering from a remarkable crisis of creativity as it has yet not found its role in a radio model based on voice locution and information genres. This article suggests the need for implementing a peripheral or heuristic strategy to attract and hold listeners’ attention. Within this framework, the narration and scene representation are proposed as suitable persuasion techniques. The objective is to design a useful conceptual tool for an efficient creative conception of narration at the service of certain commercial strategy. First, the concept of narrative persuasion is grounded according to the possibilities of the sound code. Second, the keys of scene representation and commercial strategy (brand, product, advantage, benefit and target) within the sound message are presented. And third, these keys are articulated in a model. This model is pre-tested by means of analyzing eight different case-radio ads.

Sports programs of the Spanish radio in the social network Facebook: compared study (2010-2015)

Social networks have increasingly become a showcase where the media can be promoted. Like many other media, radio stations have made use of social networks to promote themselves in a better way and, sometimes, to keep more feedback with their listeners. But not all programs make the same use and not all of them have managed to reach in the same way his followers. This article discusses the consolidation in the social networks of the major radio sports programs in Spain. Through a comparative analysis between 2010 and 2015, throughout the text, the authors have tried to observe the evolution of the programs and, at the same time, to establish comparisons between the followers that these programs have on social networks and the number of listeners as EGM.

University students with disabilities in Universities. A study of their inclusion

Access to higher education has increased among students with disabilities, and universities are adopting different alternatives which must be assessed. The purpose of this study was to identify the situation of a sample of students with disabilities (n=91) who attend a university in Spain, through the design and validation of the “CUNIDIS-d” scale, with satisfactory psychometric properties. The results show the importance of making reasoned curriculum adaptations, adapting teacher training, improving accessibility and involving all the university community. Different proposals were provided which support the social dimension of the EHEA.

Education in J.J. Rousseau: a methodological antecedent of competence based teaching

Taking into account the huge repercussion and influence that J.J. Rousseau has had on modern pedagogy, the recent tercentenary of his birth is a good opportunity to think about his outstanding relevance nowadays. This paper is a theoretical and educative research developed with an analytic and comparative hermeneutical method. The main objective is to show how some concepts of his philosophy of education have a great similarity with certain changes that the present competency based teaching is demanding, so it could be considered its methodological background. In order to achieve this objective this exposure has been divided in three parts. The first part is an analysis of Rousseau's educational theory as developed in the first three books of the Emilio, in which one of the main themes is self experience-based learning, fostering self-sufficiency, curiosity and the motivation for learning. Rousseau proposed as a method the negative education, which requires, among other conditions, a constant monitoring of the learner by the tutor. In the second part, a brief summary of the most relevant changes and characteristics of competency-based teaching is developed, as well as its purpose. The student’s participation and activity are highlighted within their own learning process through the carrying out of tasks. The new educational model involves a radical change in the curriculum, in which it is highlighted the transformation of the methodology used in the classroom as well as the role of the teacher. Finally, the aim of the third part is to offer a comparative synthesis of both proposals grouping the parallelisms found in 4 topics: origin of the two models, its aims, methodology, and change in the teaching roles.

A new teaching category at the Spanish University of Franco’s regime: the appearance on the scene of the senior lecturer

The Law of 17 July 1965 on the structure of university faculties and their teaching staff placed the figure of the university senior lecturer on stage. During the sixties, the gestation process, adoption and subsequent integration of the new figure in the academic pyramid did not escape controversy, leading to a complex phenomenon to which, however, non comprehensive studies have been devoted to reveal: how, when, why and under which conditions this teacher appeared in the Spanish University of Franco’s regime. This paper aims to provide an overview of the process of materialization of the senior lecturer, the legislative framework that definitely established this new educational category and the provisions that were in charge of regulating the processes to get tenure. Also, the first approved aggregate endowments and their distribution among universities, colleges and studies will be discussed. Finally, it was a first approach to the possible motivations that led to the creation of this new educational category in a university afflicted by serious problems waiting for a solution that had been delayed sine die. Asimismo, se analizarán las primeras dotaciones de agregados aprobadas y la distribución de las mismas por universidades, facultades y estudios. Para terminar, se realiza un primer acercamiento a las posibles motivaciones que condujeron a la creación de esta nueva figura docente en una universidad aquejada de graves problemas que esperaban a una solución que venía demorándose sine die.

The influence of video games with apocalyptic content in adolescents

The aim of this study is the dissertation and analysis of the influence (sociological, psychological and cultural) exerted on adolescents by the concept of Apocalypse. Become a key thought of visual culture, the called doomsday theory achieves one of its highest expressions in video games, possibly the favorite entertainment for young people in their leisure time. The results obtained in this research represent a first approach to the subject through the selected samples, two secondary schools from the city of Seville with disparate locations and divergent socioeconomic backgrounds. To reinforce the comparative study, we have included issues related to parental control, principal gaming platforms used by respondents or the number of hours dedicated to this type of entertainment. The conclusions demonstrate an irremediable attraction from our youth towards apocalyptic universes, plotter consciously with leisure and entertainment as escape from their routine of everyday life.

The redemption of the gaze: the crisis of observation in the "fin de siècle" and the advent of cinema

The intention of this article is not to affirm, but rather to question wether it is possible to speak of a loss of the ability to gaze in the context of the nineteenth century and especially in the context of the fin de siècle, in the bosom of the epistemological crisis that beset the Turn of the Century. And very especially, this article tries to question about the impact this crisis had, perhaps, in the birth of cinema. Is in this context that arises the work of Marey and the advent of the cinematograph of the Lumière brothers in the fin de siècle Europe, both of them showing a deep faith in a mechanical apparatus that would allow the redemption of a battered gaze. And it seems to be a dream that continues over time through the tradition of shooting the everyday life.

Optical and infrared photometry of the Type IInSN1998S: days 11-146

We present contemporaneous optical and infrared (IR) photometric observations of the Type IIn SN 1998S covering the period between 11 and 146 d after discovery. The IR data constitute the first ever IR light curves of a Type IIn supernova. We use blackbody and spline fits to the photometry to examine the luminosity evolution. During the first 2-3 months, the luminosity is dominated by the release of shock-deposited energy in the ejecta. After similar to 100 d the luminosity is powered mostly by the deposition of radioactive decay energy from 0.15 +/-0.05 M-. of Ni-56 which was produced in the explosion. We also report the discovery of an astonishingly high IR excess, K-L'=2.5, that was present at day 130. We interpret this as being due to thermal emission from dust grains in the vicinity of the supernova. We argue that to produce such a high IR luminosity so soon after the explosion, the dust must be pre-existing and so is located in the circumstellar medium of the progenitor. The dust could be heated either by the UV/optical flash (IR echo) or by the X-rays from the interaction of the ejecta with the circumstellar material.

The effect of redundancy and neutrality in genetic search

An experimental study aimed at assessing the influence of redundancy and neutrality on the performance of an (1+1)-ES evolution strategy modeled using Markov chains and applied to NK fitness landscapes is presented. For the study, two families of redundant binary representations, one non-neutral family which is based on linear transformations and that allows the phenotypic neighborhoods to be designed in a simple and effective way, and the neutral family based on the mathematical formulation of error control codes are used. The results indicate whether redundancy or neutrality affects more strongly the behavior of the algorithm used.

Delta(1232) isobar excitations and the ground state of nuclei

The influence of Delta isobar components on the ground-state properties of nuclear systems is investigated for nuclear matter as well as finite nuclei. Many-body wave functions, including isobar configurations and binding energies, are evaluated employing the framework of the coupled-cluster theory. It is demonstrated that the effect of isobar configurations depends in a rather sensitive way on the model used for the baryon-baryon interaction. As examples for realistic baryon-baryon interactions with explicit inclusion of isobar channels we use the local (V28) and nonlocal meson-exchange potentials (Bonn2000) but also a model recently developed by the Salamanca group, which is based on a quark picture. The differences obtained for the nuclear observables are related to the treatment of the interaction, the pi-exchange contributions in particular, at high momentum transfers.

Mental health of internally displaced preschool children: a cross-sectional study conducted in Bogotá, Colombia

A causa de los conflictos armados, como el de Colombia, se han desplazado por la fuerza a millones de personas, entre ellas una importante parte de la población infantil. Este estudio tuvo como objetivo evaluar la salud mental de los niños desplazados internos en edad preescolar en Bogotá Colombia, e identificar los determinantes de la salud mental en estos niños. Métodos: Estudio transversal realizado entre 279 niños que asisten a cuatro jardines infantiles en un barrio marginal de Bogotá. La salud mental infantil se evaluó con el instrumento validado de Comportamiento Infantil (CBCL) 1,5-5 años, aplicados a padres y cuidadores. Se realizo un análisis univariado y multivariado de regresión logística para evaluar la asociación entre el desplazamiento y la salud mental de los niños y para identificar las relaciones con la salud mental en los niños desplazados. Resultados: los Niños desplazados (n = 90) se identificaron con más frecuencia sobre los puntos de corte límite para las escalas CBCL que los no desplazados (n = 189) (por ejemplo, problemas totales 46,7 vs 22,8%;p \ 0,001). La asociación entre el desplazamiento y la presencia de problemas CBCL totales se mantuvo después del ajuste por factores socio-demográficos (OR Ajustado 3.3 del 95%: 1,5; 6,9). Donde la salud mental del cuidador explica en parte la asociación. En los niños desplazados, la salud mental del cuidador (p \ 0,01) y el funcionamiento familiar (p \ 0,01) se asociaron independientemente con la salud mental de los niños. La exposición a eventos traumáticos y el apoyo social también se asociaron con la salud mental del niño, sin embargo, las asociaciones no fueron independientes. Conclusión: En este barrio marginal de Bogotá, los niños en edad preescolar registrados como desplazados internos presentan peor salud mental que los no desplazados. El funcionamiento familiar y la salud mental del cuidador fueron fuerte e independientemente asociados con la salud mental de los niños y niñas desplazados.

Role of the cultural values as a key part in the implementing of healthy practices : exploratory research

El concepto de organización saludable cada vez toma más fuerza en el ámbito empresarial y académico, a razón de su enfoque integral y al impacto generado en distintos grupos de interés. Debido a su reciente consolidación como concepto, existe un limitado cuerpo de investigación en torno al tema. Para contribuir a la generación de conocimiento en este sentido, se desarrolló un estudio exploratorio el cual tenía como objetivo identificar la relación existente entre la implementación de prácticas saludables en las organizaciones y los valores culturales. En el estudio participaron 66 sujetos a quienes se les administró un cuestionario compuesto por nueve variables, cinco provenientes del modelo de Hofstede (1980) y cuatro más que evaluaban la implementación de prácticas organizacionales saludables. Los resultados obtenidos muestran que los valores culturales predicen la implementación de prácticas saludables.
