Connected teens: Measuring the impact of mobile phones on social relationships through social capital
Authors: Vidales-Bolaños María-José , Sádaba-Chalezquer Charo 
Published: July 2017

Over the past twenty years, the high penetration of mobile phones as a means of interpersonal communication, especially among adolescents, has facilitated access to broader social environments outside their own family. Through the extension of their social environment, teenagers are able to establish new and more extensive relationships, while facing risks that may negatively affect their socialization process. The aim of this article was to find out how computer-mediated communication helps or obstructs the creation of social capital between teenagers, and what are the consequences of its use for this age group. To achieve this, an index of social capital was developed in the study, designed to determine the positive or negative impact of certain components of mobile mediated communication in the creation of this intangible resource. Questionnaires were distributed among Spanish adolescents of secondary and high school age, from different public and private schools of Navarre. Furthermore, the study considered the adolescents’ own perceptions about the incidence of the use of mobile phones in their social relationships. As reflected in the results, to identify the components of mediated communication that significantly affect social capital it is necessary to conduct an objective measurement of this resource.
La alta penetración del teléfono móvil entre los adolescentes y su uso como medio de comunicación inter-personal ha facilitado para este público el acceso, durante los últimos veinte años, a entornos más amplios, distintos al familiar. A través de la extensión de su ámbito social, estos son capaces de establecer nuevos vínculos y relaciones más extensas, al tiempo que se enfrentan a riesgos que afectan de manera negativa a su proceso de socialización. El objetivo de este trabajo fue conocer de qué manera la comunicación mediada por la tecnología favorece o no la creación de capital social entre las comunidades de adolescentes, y cuáles son las consecuencias que pueden resultar de su uso para este grupo de edad. Para ello se propuso un índice de capital social, que permitiera conocer el impacto positivo o negativo que tienen determinados componentes de la comunicación mediada por el móvil en la creación de este recurso. Se repartieron cuestionarios entre jóvenes españoles de la ESO y Bachillerato, en colegios públicos y privados de la Comunidad Foral de Navarra. Además, se tuvo en cuenta la propia percepción de los adolescentes, sobre la incidencia del uso de este dispositivo en sus relaciones sociales. Tal como reflejan los resultados, solo a través de una medición objetiva del capital social es posible identificar aquellos componentes de la comunicación mediada que afectan de manera significativa a este recurso.
Social empowerment in Mexican violent contexts through media competence
Authors: Grijalva-Verdugo Abel-Antonio , Moreno-Candil David 
Published: July 2017

The acquisition of digital skills, media diet management, and general knowledge of ICT, is essential for the development and empowerment of audiences in the current media ecology, particularly considering the political and social challenges of the Latin American environment. In that sense, the study of media competence is urgent for sizing up the needs and characteristics of these communities. This work analyses the axiological and ideological dimension of media competence during an electoral process in northwestern Mexico, a region that is generally subject to violence related to organized crime. Twenty-three items pertaining to this dimension were selected from an instrument designed to evaluate media competence, which were applied to a probability sample of 385 subjects divided by digital natives, digital migrants, and digital illiterates. After an exploratory factor analysis, seven factors were identified. The intra and inter-group scores were explored, lower scores were found in components that allude citizens’ participation and social action; likewise, three of seven factors showed statistically significant differences, being digital natives who reported a lower score. Therefore, the need to search for new strategies for citizens to acquire media competence is evident, in order for pro-summing to become a social empowerment tool.
En las actuales ecologías mediáticas la adquisición de saberes digitales, manejo de dieta de medios y dominios generales de las TIC son fundamentales para el desarrollo y el empoderamiento de las audiencias, en particular, al considerar los desafíos políticos y sociales de entornos como el latinoamericano. Así, el estudio de la competencia mediática es urgente para dimensionar las necesidades y características de estas comunidades. La presente investigación analiza la dimensión axiológica e ideológica de la competencia mediática durante un proceso electoral en el noroeste de México, región que se ha caracterizado por la violencia relacionada con el crimen organizado. A partir de un instrumento diseñado para evaluar dicha competencia, se seleccionaron 23 ítems que remiten a la dimensión señalada, este se aplicó por medio de un muestreo probabilístico a 385 sujetos divididos en nativos, inmigrantes y analfabetos digitales. Tras un análisis factorial exploratorio se identificaron siete factores que conforman la dimensión axiológica e ideológica. Se exploraron las puntuaciones intra e intergrupos y se encontraron puntuaciones bajas en componentes que aluden a la participación ciudadana y a la movilización social; asimismo, tres de los siete factores presentaron diferencias estadísticamente significativas, siendo los nativos digitales quienes reportaron valores más bajos. Así, se pone en evidencia la necesidad de buscar nuevas estrategias para que los ciudadanos adquieran la competencia mediática y que así el prosumo se vuelva una herramienta de empoderamiento social.

Published: July 2017

In Peru, young college students have leading roles in social protest mobilizations even when they seldom belong to political organizations. This study aims to analyze the perception of current politics and its institu-tions among young college students, and to inquire into their interest on relevant events at their surround-ings and into the importance gained by the media and the social networks concerning their information. The purpose of this project is also to examine the role assigned by college students to the university as a space of personal development and reflection. This project was carried out in Lima, Peru, directed to youngsters aged 17 to 25 from public and private universities. Opinions have been collected through six focus-groups and a survey applied to more than 400 students. The analysis concludes that college students distrust pro-foundly political parties and formal political organizations; likewise it shows they have a broad access to information sources, so as their willingness to solve Peru’s problematic issues. It also uncovers clear differ-ences between students of private and public universities regarding attitudes for participating in political action, inside and outside the campus. From the study stems a proposal to provide young students at their campuses with opportunities to debate public issues of national and global interest as a part of their overall academic training.
En el Perú, los jóvenes universitarios son protagonistas de movilizaciones de protesta social aun cuando es escasa su pertenencia a organizaciones políticas. Esta investigación tiene como objetivos analizar la per-cepción que tienen los jóvenes universitarios limeños sobre la política y sus instituciones e indagar acerca de su interés por los sucesos relevantes de su entorno y la importancia que adquieren los medios de co-municación y las redes digitales para su información. El trabajo también se propuso examinar el rol que los universitarios le asignan a la universidad como espacio de formación y reflexión. El estudio se realiza en Lima, Perú, con jóvenes de 17 a 25 años, de universidades públicas y privadas. Las opiniones se recogen en seis grupos focales y una encuesta aplicada a más de 400 estudiantes. El análisis concluye que los universitarios desconfían profundamente de los partidos políticos y las organizaciones políticas formales; asimismo, se evidencia que gozan de amplio acceso a fuentes de información y están dispuestos a contri-buir a la solución de los problemas que aquejan a su país. El estudio desvela diferencias marcadas entre estudiantes de universidades públicas y privadas en su disposición para participar en actividades políticas, dentro y fuera del ámbito universitario. La investigación propone que la universidad ofrezca a los jóvenes oportunidades para el debate de los asuntos públicos de interés nacional y global en su formación integral.
Parent’s influence on acquiring critical Internet skills

Published: July 2017

The accessibility and easeofuse for children of information and communication technologies lead us to suggest that one of the key questions for their potential empowerment is linked to their analytical use by means of the acquisition of critical skills. The family environment is considered an important factor in digital literacy and the education of critical citizens. The present paper analyzes the mediation role of the parents in their children’s education. It shows a predictive model that includes parental education style and their trust in the interactive media for their children’s acquisition of critical cognitive abilities. It also identifies the personal and contextual factors that are related to the parental education style. The model was tested on a representative sample of 765 families from the Madrid Community selected on the educational level, center type, and district income bases. It was found that children’s educational level is the factor of greatest impact on the acquisition of critical abilities. Nevertheless, as parents adopt a less restrictive style regarding the uses of Internet, there is a more positive influence on the acquisition of critical abilities independently of the age effect. The results question the role of parental restrictions on the use of the interactive media to encourage the education of critical citizens.La accesibilidad y facilidad de uso de las tecnologías de la información y la comunicación en los menores lleva a plantear que una de las cuestiones clave para su potencial de empoderamiento está vinculada al uso crítico de las mismas a través de la adquisición de habilidades críticas. El entorno familiar se postula como un factor determinante en la alfabetización digital y en la formación de ciudadanos críticos. El presente trabajo analiza el papel mediador de los padres en la educación de sus hijos. Plantea un modelo compresivo que recoge la influencia del estilo parental y la confianza de los progenitores hacia el medio interactivo en la adquisición de habilidades críticas por parte de los menores y se identifican los factores personales y contextuales que influyen sobre el estilo parental. El modelo se pone a prueba con una muestra representativa de 765 familias procedentes de la Comunidad de Madrid seleccionadas en función del nivel de enseñanza, tipología de centro y nivel de renta del distrito. Se comprueba que el nivel educativo de los hijos es el factor más influyente en la adquisición de habilidades críticas. No obstante, cuanto menos restrictivo es el estilo de control parental de Internet, más positivamente influye en la adquisición de habilidades independientemente de la edad. Los resultados cuestionan el papel de las restricciones en el uso del medio interactivo para la formación de ciudadanos críticos.
Effect of 4-Month Intermittent Atropine Penalization in Amblyopic Children for Whom Patch Therapy Had Failed
Authors: Seol Bo Ram , Yu Young Suk , Kim Seong-Joon 
Published: July 2017

Purpose:
To evaluate the effect of 4-month intermittent atropine penalization in children with amblyopia for whom patch therapy had failed and to analyze the factors associated with treatment success.

Methods:
This retrospective observational study included participants who visited the hospital between January 1, 2011, and December 31, 2015. Forty-one children with amblyopia for whom patch therapy had failed were included and their medical records were analyzed retrospectively. They were treated with 1% atropine eye drops in the sound eye twice per week for 4 months. Treatment success was defined as a best corrected visual acuity (BCVA) improvement of two lines in the amblyopic eye. Age, cause of amblyopia, pretreatment BCVA at the start of atropine penalization in the amblyopic eye, age at the start of eyeglass prescription, age at the start of patch therapy, duration, compliance with and total amount of patch therapy, type of refraction, type of strabismus, and cause of failure of patch therapy were analyzed and compared between two groups: the failure and success groups.

Results:
Twenty of 41 patients (48.8%) showed treatment success. The mean age was 5.59 ± 1.52 years and the mean BCVA of the amblyopic eye was 0.40 ± 0.20 logarithm of the minimum angle of resolution (logMAR). Younger age and poor pretreatment BCVA at the start of atropine penalization in the amblyopic eye were the factors associated with treatment success.

Conclusions:
Intermittent atropine penalization for 4 months can improve BCVA in children with amblyopia for whom patch therapy has failed. Atropine penalization can be especially effective in younger children and those with poor BCVA at the start of atropine penalization in the amblyopic eye.

Rebeca Lane : « libre, atrevida y loca », la liberación del cuerpo por una rapera feminista de Guatemala
Authors: Gondouin Sandra 
Published: July 2017

Rebeca Lane, « artivista » guatemalteca, es una de las pocas mujeres de Centroamérica que ha entrado a la escena del hip hop. Desarrolla un discurso feminista en el que la representación del cuerpo aparece como céntrica, tanto desde la imagen visual como poética. En sus canciones, reinventa mitos « femeninos », afirma el orgullo de ser mujer y cuestiona la memoria colectiva y las identidades de género desde el motivo del cuerpo. Ahora bien, el cuerpo desempeña un papel fundamental en las reflexiones feministas contemporáneas, en tanto que espacio colonizado que las mujeres buscan reapropiarse, a través del arte en particular. El hecho de que Rebeca Lane tenga una formación de socióloga puede explicar la potencia de su discurso artístico, tanto visual como textual. En efecto, sus canciones y videoclips traducen una reflexión social y unos planteamientos feministas contra-hegemónicos sólidos, con una sensibilidad cercana al feminismo comunitario. Así, Rebeca Lane subvierte la tradición muy machista del rap, decolonizando y liberando el cuerpo de mujer. Veremos cómo su rap llega a ser un instrumento de empoderamiento y reconstrucción de la identidad de mujer, pero también de recuperación de la memoria colectiva y sanación del cuerpo social.
Cinéma, genre et politique en Argentine : Ana Amado et ses sœurs
Authors: Mullaly Laurence H. 
Published: July 2017

Parmi les universitaires argentines qui ont fait l’expérience du militantisme et de la répression, puis de l’exil et du retour, Ana Amado, décédée en novembre 2016, est une des figures intellectuelles dont le féminisme a toujours nourri les pratiques. Son positionnement critique en tant que spécialiste du cinéma argentin participe de la lutte contre une dépolitisation programmée par la plupart des pouvoirs en place depuis la fin de la dictature. Ses publications témoignent de son intérêt pour les interventions artistiques d’une « nouvelle » génération qui convoque autrement l’histoire, la politique et les identités au sein du champ socioculturel argentin.
New Ferrimagnetic Garnets for LTCC-Technology Circulators

Published: July 2017

Abstract
Yttrium iron garnet-based ferrites are used in nonreciprocal devices like microwave circulators and isolators. The low dielectric and magnetic losses of those materials provide the required properties. The main drawbacks of circulators are their size and cost, due to complex mechanical assembling of the different materials. To simplify the complex manufacturing process, a possible solution would be to adapt the different materials to a common low temperature cofired ceramic (LTCC) process: the circulators would be produced with an additive multilayer process. We showed that cationic substitutions (bismuth and copper) enable a considerable decrease of the sintering temperature of garnets, from ~1,450°C to down to ~950°C. Furthermore, due to bismuth cations, a high permittivity is achieved, allowing the reduction of the circulator core size. Our most recent results show that it is possible to decrease this temperature down to 880°C, thanks to vanadium substitutions. This significant decrease of the sintering temperature leads to a compatible material for cofiring with gold and particularly with silver (melting points 1,064°C and 962°C, respectively). Different assemblies of tapes were studied: ferrite with silver or gold, ferrite with dielectric and ferrite with dielectric and metallization. Physical analyses (dilatometry, coefficient of thermal expansion, etc.) are exposed and magnetic and dielectric properties (permittivity and saturation magnetization) are discussed. Moreover, the first results of circulators in LTCC technology with gold and silver screen printing are presented (transmission, isolation, and return loss) and the compatibility of the different elements is analyzed.
Investigations on the Additive Manufacturing and Heavy Wire Bonding Capability of Selective Laser-Melted Circuit Carriers

Published: July 2017

Abstract
Additive manufacturing (AM) provides tool-free and direct manufacturing of complex geometries simultaneously integrating various functions into components. Though AM techniques are widely used in various sectors, the application into electronics production has not yet been explored. In electronics production, substrate development has high relevance due to their multifunctionality through electrically connecting components and providing mechanical support. This contribution introduces an innovative approach based on selective laser melting (SLM) in the development of high-temperature substrates through additive layered manufacturing. Furthermore, possibilities and challenges that come along with the process combination of SLM and heavy wire bonding are investigated. Wire bonding capability is analyzed on untreated as well as on postprocessed surfaces. The influence and effectiveness of various steps of postprocessing such as cleaning, sand blasting, and grinding are analyzed. Thus, interdependencies between both manufacturing process as well as postprocessing can be revealed. The effect of surface roughness and hardness of the assembly partner are investigated as well. The primary characteristics besides the bond parameters that influence the wire bonding capability are focused in this article. The process stability and the interconnection quality are evaluated by optical nondestructive laser microscopic analysis. Destructive pull and shear tests and metallographic cross sections are performed to evaluate the adhesion characteristics. By a profound understanding of all interdependencies between the two processes, a flexible manufacturing technology for power devices can be established.
Doing theology in multi-world contexts
Authors: Meylahn Johann-Albrecht 
Published: July 2017

This article seeks to respond to the challenge of doing theology in multi-world contexts, by understanding how these multiple worlds appear. Understanding the role of power in the appearance of these different worlds helps in the deconstruction of dominant worlds, but it leaves one with relativism, and consequently apathy. The article presents a Christo-fiction as a praxis of doing theology in multi-worlds as a way beyond such relativism.
La realidad aumentada aplicada al aprendizaje en personas con Síndrome de Down: un estudio exploratorio
Authors: Martín-Sabarís Rosa-María , Brossy-Scaringi Gerardo 
Published: July 2017

La Realidad Aumentada es una tecnología en creciente auge en los campos de la comunicación, la educación, la medicina, el marketing, la arquitectura o el entretenimiento, pero sigue estando dirigida a públicos hegemónicos. El objetivo de este trabajo es explorar su utilidad en la comunicación y el aprendizaje de personas con Síndrome de Down. Metodología: Para ello se diseñó, ejecutó y evaluó una experiencia de RA consistente en la visita de tres grupos de sujetos con esta patología a dos museos de la ciudad de Bilbao asistidos por una aplicación móvil. Resultados y conclusiones: Los resultados muestran que un mayor grado de maduración cognitiva y el uso previo de TIC influyen en una mejor experiencia de usuario, pero no son determinantes. Esta tecnología es útil en su desplazamiento por la vía pública, lo que permite una mayor autonomía y, en consecuencia, una mejora en la calidad de vida. El componente visual resulta de gran ayuda en el mantenimiento de la atención, la adquisición de información y en la memoria a largo plazo, lo que sugiere la necesidad de desarrollar herramientas e implementar programas específicos para estas personas.
Automatically Representing TExt Meaning via an Interlingua-based System (ARTEMIS). A further step towards the computational representation of RRG
Authors: Mairal-Usón Ricardo , Cortés-Rodríguez Francisco 
Published: July 2017

Within the framework of FUNK Lab – a virtual laboratory for natural language processing inspired on a functionally-oriented linguistic theory like Role and Reference Grammar-, a number of computational resources have been built dealing with different aspects of language and with an application in different scientific domains, i.e. terminology, lexicography, sentiment analysis, document classification, text analysis, data mining etc. One of these resources is ARTEMIS (<span style="text-decoration: underline;">A</span>utomatically <span style="text-decoration: underline;">R</span>epresenting <span style="text-decoration: underline;">TE</span>xt <span style="text-decoration: underline;">M</span>eaning via an <span style="text-decoration: underline;">I</span>nterlingua-Based <span style="text-decoration: underline;">S</span>ystem), which departs from the pioneering work of Periñán-Pascual (2013) and Periñán-Pascual &amp; Arcas (2014). This computational tool is a proof of concept prototype which allows the automatic generation of a conceptual logical structure (CLS) (cf. Mairal-Usón, Periñán-Pascual and Pérez 2012; Van Valin and Mairal-Usón 2014), that is, a fully specified semantic representation of an input text on the basis of a reduced sample of sentences. The primary aim of this paper is to develop the syntactic rules that form part of the computational grammar for the representation of simple clauses in English. More specifically, this work focuses on the format of those syntactic rules that account for the upper levels of the RRG Layered Structure of the Clause (LSC), that is, the <em>core</em> (and the level-1 construction associated with it), the <em>clause</em> and the <em>sentence </em>(Van Valin 2005). In essence, this analysis, together with that in Cortés-Rodríguez and Mairal-Usón (2016), offers an almost complete description of the computational grammar behind the LSC for simple clauses.
