Advocacy of trafficking campaigns: A controversy story
Authors: Saiz-Echezarreta Vanesa , Alvarado María-Cruz , Gómez-Lorenzini Paulina 
Published: February 2018

The construction, visualization, and stabilization of public problems require the mobilization of civil society groups concerned about these issues to actively engage in the demand for actions and policies. This paper explores the institutional campaigns against human trafficking and sexual exploitation in Spain between 2008 and 2017 and their role in helping to shape this issue as a matter of public concern. Our aim is to identify the ideological basis of these campaigns through their representations of predominant actors, which have been systematized to identify possible mistakes and to help determine more effective actions with a greater capacity for mobilization. We applied a mixed content analysis combined with a semiotic model to evaluate the presence or absence of the different actors and their relevance in each case. Several lines of discourse have been reiterated across the 50 campaigns analysed: Curbing the demand for prostitution as a priority objective; the centrality of victims in the representations; the role of the consumer of paid sex as an accomplice to the crime; and the correlation between prostitution and human trafficking. We will also examine how these issues relate to the broader dispute on the status of prostitution in Spain. This will require a conceptual shift away from educational and social-oriented communication towards the structural causes, collective responsibility and transformative justice frameworks.
La construcción, visibilización y estabilización de un problema público requiere de la movilización de colectivos ciudadanos interesados en el asunto, que actúen como un ente activo en la reclamación de acciones y políticas. Este artículo analiza las campañas contra la trata de personas con fines de explotación sexual en España (2008-2017) desde su contribución a la conformación de esta cuestión como un problema de carácter público. El objetivo es identificar los ejes ideológicos desde los que han operado estas campañas, a través de las representaciones que se han sistematizado de sus protagonistas para identificar posibles errores y orientar acciones de mayor eficiencia y capacidad movilizadora. Se ha aplicado un análisis de contenido mixto complementado con un análisis semiótico, considerando la presencia o ausencia de los distintos actores y su mayor o menor protagonismo en cada caso. En las cincuenta campañas analizadas se constata la reiteración de varias líneas discursivas: la prioridad en desincentivar la demanda de prostitución, la centralidad de las víctimas en la representación, la figura del demandante de sexo de pago como cómplice del delito y la equiparación de prostitución y trata. Son discursos que intervienen en una controversia más amplia sobre el estatuto de la prostitución en el país y que necesitan reorientarse, desde la educomunicación y la comunicación con fines sociales, hacia las causas estructurales, la responsabilidad colectiva y la denuncia transformadoras.
#TrumpenMexico. Transnational connective action on Twitter and the border wall dispute
Authors: Meneses María-Elena , Martín-del-Campo Alejandro , Rueda-Zárate Héctor 
Published: February 2018

This article aims to identify how digital public opinion was articulated on Twitter during the visit of the Republican presidential candidate Donald Trump to Mexico City in 2016 by invitation from the Mexican government, which was preceded by the threat to construct a border wall that Mexico would pay for. Using a mixed methodology made up of computational methods such as data mining and social network analysis combined with content analysis, the authors identify conversational patterns and the structures of the net-works formed, beginning with this event involving the foreign policy of both countries that share a long border. The authors study the digital media practices and emotional frameworks these social network users employed to involve themselves in the controversial visit, marked by complex political, cultural and historical relations. The analysis of 352,203 tweets in two languages (English and Spanish), those most used in the conversations, opened the door to an understanding as to how transnational public opinion is articulated in connective actions detonated by newsworthy events in distinct cultural contexts, as well as the emotional frameworks that permeated the conversation, whose palpable differences show that Twitter is not a homogeneous universe, but rather a set of universes co-determined by sociocultural context.
El presente artículo busca identificar cómo se articuló la opinión pública digital en la red social Twitter durante la visita del entonces candidato republicano Donald Trump a la Ciudad de México en el año 2016 por invitación del gobierno mexicano que fue precedida de la amenaza de construir un muro fronterizo que pagaría México. Mediante una metodología mixta compuesta por métodos computacionales tales como minería de datos y análisis de redes sociales combinado con análisis de contenido se identifican los patrones de la conversación y las estructuras de redes que se conformaron a partir de este acontecimiento de la política exterior de ambas naciones que comparten una extensa frontera. Se estudiaron las prácticas mediáticas digitales y los encuadres emocionales con los cuales los usuarios de esta red social se involucraron en la controversial visita marcada por una compleja relación política, cultural e histórica. El análisis de 352.203 tuits en dos idiomas (inglés y español), los más utilizados en las conversaciones, permitió comprender cómo se articula la opinión pública transnacional en acciones conectivas detonadas por eventos noticiosos en contextos culturales distintos, así como los encuadres emocionales que permearon la conversación, cuyas diferencias palpables demuestran que cuando se habla de Twitter no se trata de un universo homogéneo, sino de un conjunto de universos codeterminados por el contexto sociocultural.
YouTuber videos and the construction of adolescent identity
Authors: Pérez-Torres Vanesa , Pastor-Ruiz Yolanda , Abarrou-Ben-Boubaker Sara 
Published: February 2018

The main objective of this research is to analyze the content of YouTuber's videos that have the greatest impact on adolescents and their relationship with the construction of identity. The YouTube platform is one of the most commonly used by Spanish teenagers and around 70% of young people between 14 and 17 years of age prefer this network. YouTubers are perceived by young people as their equals, approachable people who share similar traits to their own, which facilitates rapid identification. A qualitative analysis of the content of 22 videos on the YouTube platform was carried out using the Atlas.ti program. The analysis led to several emerging codes related to the construction of adolescent personal identity. Most of the messages relating to personal identity were aimed at transmitting the self-impression of the YouTuber and the relationship of that self-impression with his gender identity, sexual orientation, and vocational identity. Also, family and peers appeared in the videos, especially as providers of social support. Teen followers include messages to support YouTubers, express their identification with the messages and use comment spaces to describe their own experiences, expressing the same concerns in the configuration of their identity. It is necessary to take into account this new space of interrelation to understand the development of young people’s identity.
El objetivo general de esta investigación consiste en analizar el contenido de los vídeos de los youtubers de mayor impacto entre los adolescentes y su relación con la construcción de la identidad. La plataforma YouTube es una de las más utilizadas por los adolescentes españoles, ya que alrededor del 70% de los jóvenes entre 14 y 17 años prefieren esta red. Los youtubers son percibidos por los jóvenes como sus iguales, personas cercanas que comparten rasgos similares a los suyos, lo que facilita la rápida identificación con ellos. Se ha realizado un análisis cualitativo del contenido de 22 vídeos de la plataforma YouTube mediante el programa Atlas.ti. El análisis ha dado lugar a varios códigos emergentes relacionados con la construcción de la identidad personal en la adolescencia. La mayoría de los mensajes sobre la identidad personal estaban orientados a transmitir la autodefinición que hace el youtuber sobre sí mismo y la relación de esa autoimagen con su identidad de género, orientación sexual e identidad vocacional. Además, la familia y los iguales aparecen en los vídeos, especialmente como proveedores de apoyo social. Los seguidores adolescentes incluyen mensajes de apoyo al youtuber, manifiestan su identificación con los mensajes y utilizan los espacios de comentarios para exponer sus experiencias personales, expresando las mismas inquietudes en la configuración de su identidad. Es necesario tener en cuenta este nuevo espacio de interrelación en la comprensión del desarrollo identitario de los jóvenes.
Gamification and transmedia for scientific promotion and for encouraging scientific careers in adolescents
Authors: Pérez-Manzano Antonio , Almela-Baeza Javier 
Published: February 2018

The current growth in gamification-based applications, and especially in what is known as Digital Game-based Learning (DGBL), is providing new opportunities with considerable educational potential. In the present study, we report on the results of the progress of a project for developing a setting for a gamified website carried out ad hoc, complemented by transmedia resources and aimed at scientific promotion and the promotion of technological and scientific careers (S&T) in adolescents, who are at a stage in life when career preferences are established. At present, the decrease in S&T careers is one of the greatest problems for the society of technological development that we live in, where the number of professionals working in key areas for economic development and progress is declining. After completing a pre and post project participation survey, the results suggest a high level of efficiency achieved by projects of this type due to their online experimentation design, the knowledge of real cases of research activity, and the communication of positive scientific values and attitudes appropriate for the target population. The participants significantly increased their interest in the subject area, scientific professions, and research activity and their social benefits demonstrating the acquisition of positive attitudes towards scientific knowledge and skills.En la actualidad la proliferación de aplicaciones basadas en gamificación y especialmente en el denominado Aprendizaje Digital Basado en Juegos (Digital Game-Based Learning, DGBL) abre un panorama de elevado potencial educativo. En el presente trabajo se muestran los resultados del desarrollo de un proyecto con el funcionamiento de un entorno web gamificado y realizado ad hoc, complementado con recursos transmedia y dirigido a la divulgación científica y al fomento de las vocaciones científico-tecnológicas (CyT) en adolescentes, siendo precisamente en este rango de edad donde se configura la preferencia vocacional. El descenso de vocaciones CyT supone uno de los mayores problemas actuales para la sociedad de desarrollo tecnológico en la que nos encontramos, con un descenso generalizado de profesionales en áreas claves para el desarrollo económico y de progreso. Tras la realización de una encuesta previa a la participación en el proyecto y la misma encuesta tras la realización del mismo, los resultados obtenidos indican la elevada eficacia de proyectos de este tipo, diseñados en base a la experimentación online, el conocimiento de situaciones reales de la actividad investigadora y la comunicación de valores y actitudes procientíficas de forma afín a la población objetivo. Los participantes aumentan significativamente su interés por la profesión científica, la actividad investigadora y su beneficio social manifestando la adquisición de conocimientos y destrezas procientíficas y poniendo de relieve su interés por la temática tratada.
From sMOOC to tMOOC, learning towards professional transference. ECO European Project

Published: February 2018

The evolution of MOOCs in the last decade has been constant and dynamic. The first cMOOC and xMOOC models eventually evolved into different postMOOC modalities, such as sMOOC, which conjugates interaction among students with a participation model based on social networks. This work is focused on carrying out a systematic review of the state-of-the-art scientific literature referred to the concept of MOOC and its diverse types. Moreover, in this article, a new generation associated to sMOOC is unveiled: the tMOOC (Transfer Massive Open Online Courses). The methodology of study is based on the content analysis of those categories resulting after compiling 707 entries from Web of Science, plus an in-depth study of the 70 articles which were quoted at least 10 times. In addition, a case study has been carried out from European ECO Project’s “sMOOC Step by Step”, as an example of innovative pedagogical model based on collaborative learning to train future e-teachers. The results of the analysis show the very recent –and still scarce– research on the different types of MOOCs, as well as the finding of a new modality based on pedagogical transformation, learning transference and intercreative talent. As a conclusion, the analysis of all key factors in the configuration of tMOOC has encouraged us to propose a new taxonomy based on the 10 T’s.La evolución de los MOOC en la última década ha sido constante y dinámica. Como antecedentes, los primeros modelos de cMOOC y xMOOC se transforman en otras modalidades postMOOC, como los sMOOC, que conjugan la interacción entre los estudiantes con el modelo de participación implantado en las redes sociales. Este trabajo tiene como objetivo realizar una revisión sistemática del estado de la literatura científica sobre el concepto MOOC y sus distintas tipologías. En este artículo, se descubre una nueva generación asociada a los sMOOC, los tMOOC (Transfer Massive Open Online Courses). La metodología de estudio se basa en el análisis de contenido de las categorías resultantes en los 707 registros recogidos de Web of Science, profundizando en los 70 artículos que obtuvieron al menos diez citas. Además, se ha realizado el estudio de caso del sMOOC «Paso a paso» del Proyecto Europeo ECO, como modelo pedagógico innovador, centrado en el aprendizaje colaborativo para la formación de futuros e-teachers. Los resultados del análisis muestran la reciente y escasa investigación sobre los diferentes tipos de MOOC, así como el hallazgo de una nueva modalidad basada en la transformación pedagógica, la transferencia del aprendizaje y el talento intercreativo. Como conclusión, el análisis de todas las claves de la configuración del tMOOC nos lleva a proponer una nueva taxonomía basada en las 10 T’s.
Possibility of critical practice in computational design: applications on boundaries between public and private space
Authors: Kimmel Laurence 
Published: February 2018

La conception par ordinateur permet de créer des surfaces transformatives complexes qui tendent à gommer les limites entre espaces de différents statuts. Cet article porte sur les possibilités de développer une pratique artistique et critique de la conception par ordinateur, permettant ainsi l’émergence d’événements dans le système en transformation, et donc de l’« affect ». La possibilité de jouer sur les limites entre espaces de différents statuts nécessite de maintenir les notions d’espace public et d’espace privé (les technologies et leurs capacités à connecter tout espace dans un même réseau économique tend à effacer ces différences) de manière à permettre un entrelacement créatif de ces derniers. La possibilité de transformer ces limites pose la question de l’entité légitime pour contrôler cette évolution. En maintenant une distance avec les extrêmes que sont la liberté totale tendant vers un soi-disant ‘Bien ultime’ d’un côté, et une liberté niée par une « loi » excessive de l’autre côté, l’article présente des manières dont une communauté pourrait reprendre le contrôle de son environnement grâce aux nouvelles technologies, tant qu’une « loi commune » pour la vie publique est respectée. La manière dont les paramètres et algorithmes pourraient être ajustés afin de fonctionner selon ce modèle est utopique mais théoriquement faisable dans le futur selon les théories de l’« émergence ». Le maintien de la possibilité d’événements et de singularités créatives dans le système maintient un espace pour la pensée critique en architecture, prenant en compte la mémoire et la volonté d’un futur meilleur.
Biomass burning CCN enhance the dynamics of a mesoscale convective system over the La Plata Basin: a numerical approach
Authors: Camponogara Gláuber , Faus da Silva Dias Maria Assunção , Carrió Gustavo G. 
Published: February 2018

Abstract. High aerosol loadings are discharged into the atmosphere every year by biomass burning in the Amazon and central Brazil during the dry season (July–December). These particles, suspended in the atmosphere, can be carried via a low-level jet toward the La Plata Basin, one of the largest hydrographic basins in the world. Once they reach this region, the aerosols can affect mesoscale convective systems (MCSs), whose frequency is higher during the spring and summer over the basin. The present study is one of the first that seeks to understand the microphysical effects of biomass burning aerosols from the Amazon Basin on mesoscale convective systems over the La Plata Basin. We performed numerical simulations initialized with idealized cloud condensation nuclei (CCN) profiles for an MCS case observed over the La Plata Basin on 21 September 2010. The experiments reveal an important link between CCN number concentration and MCS dynamics, where stronger downdrafts were observed under higher amounts of aerosols, generating more updraft cells in response. Moreover, the simulations show higher amounts of precipitation as the CCN concentration increases. Despite the model's uncertainties and limitations, these results represent an important step toward the understanding of possible impacts on the Amazon biomass burning aerosols over neighboring regions such as the La Plata Basin.
Increased West Antarctic and unchanged East Antarctic ice discharge over the last 7 years

Published: February 2018

Abstract. Ice discharge from large ice sheets plays a direct role in determining rates of sea-level rise. We map present-day Antarctic-wide surface velocities using Landsat 7 and 8 imagery spanning 2013–2015 and compare to earlier estimates derived from synthetic aperture radar, revealing heterogeneous changes in ice flow since ∼ 2008. The new mapping provides complete coastal and inland coverage of ice velocity north of 82.4° S with a mean error of < 10 m yr−1, resulting from multiple overlapping image pairs acquired during the daylight period. Using an optimized flux gate, ice discharge from Antarctica is 1929 ± 40 Gigatons per year (Gt yr−1) in 2015, an increase of 36 ± 15 Gt yr−1 from the time of the radar mapping. Flow accelerations across the grounding lines of West Antarctica's Amundsen Sea Embayment, Getz Ice Shelf and Marguerite Bay on the western Antarctic Peninsula, account for 88 % of this increase. In contrast, glaciers draining the East Antarctic Ice Sheet have been remarkably constant over the period of observation. Including modeled rates of snow accumulation and basal melt, the Antarctic ice sheet lost ice at an average rate of 183 ± 94 Gt yr−1 between 2008 and 2015. The modest increase in ice discharge over the past 7 years is contrasted by high rates of ice sheet mass loss and distinct spatial patters of elevation lowering. The West Antarctic Ice Sheet is experiencing high rates of mass loss and displays distinct patterns of elevation lowering that point to a dynamic imbalance. We find modest increase in ice discharge over the past 7 years, which suggests that the recent pattern of mass loss in Antarctica is part of a longer-term phase of enhanced glacier flow initiated in the decades leading up to the first continent-wide radar mapping of ice flow.
SMART THERMOPLASTIC ELASTOMERS WITH HIGH EXTENSIBILITY FROM POLY (VINYLIDENE FLUORIDE) AND HYDROGENATED NITRILE RUBBER: PROCESSING–STRUCTURE–PROPERTY RELATIONSHIP
Authors: Saha Subhabrata , Bhowmick Anil K. 
Published: February 2018

ABSTRACT
Novel smart thermoplastic elastomers (TPEs) with very high extensibility were prepared by blending polyvinylidene fluoride (PVDF) with hydrogenated nitrile rubber (HNBR) at an appropriate ratio, and their processing–structure–property relationship was investigated. Although the rubber phase was found to be dispersed in the matrix of PVDF for all compositions, morphology was shear sensitive and changed significantly after each processing step. Dropletlike structure was observed after the mixing in an internal mixer and compression molding, which changed to the lamellar structure after milling and injection molding. The compression molded sample exhibited very high extensibility (∼1600% elongation at break for 30/70 PVDF/HNBR blend) and a tensile strength of ∼6 MPa due to the formation of a strong interface. The elongation at break was much higher than any of the TPEs reported so far. Theoretical calculation of rubber particle size was also in agreement with the experimental observation. Dissipative particle dynamics simulation was run to capture the morphology, where HNBR chains were more sensitive to the shear force than the PVDF chains. The electromechanical sensitivity of the blend was 14.3 MPa−1, much better than the existing reported elastomeric actuator as well as pristine PVDF. Dynamic vulcanization gave further improvement in tensile strength and tension set properties.
