Este trabajo pretende replicar con muestras españolas un estudio americano diseñado para evaluar las relaciones entre el rasgo Búsquesa de Sensaciones, Extraversión, Neuroticismo y Psicoticismo, con el interés por la contemplación o lectura de sucesos violentos, morbosos y sexuales en los medios de comunicación (o reales). El estudio se realizó a partir de inventarios autoinformados de curiosidad morbosa, cuestionarios de personalidad y autopuntuaciones de asistencia a películas pornográficas y de terror. Los resultados obtenidos informan de una relación positiva entre las escalas de Búsqueda de Sensaciones (EBS) y las escalas de Curiosidad Morbosa (CTM-CTS). Ello sugiere como hipótesis que los altos buscadores de sensaciones podrían estar interesados en estímulos que aumentan la actividad del sistema central de catecolaminas. Para ello se parte de hallazgos experimentales previos que apuntan que películas morbosas de terror o sexuales aumentan los niveles de las catecolaminas periféricas.

La publicación en 1977 de "A critical bibliography of Hispanic Arthurial material", de Harvey L. Sharrer (Londres, Grant & Cutler) contribuyó a un mejor conocimiento de los textos conservados, ediciones y estudios de la literatura artúrica y tristaniana medieval en España y Portugal. Treinta años después, este artículo amplía los contenidos de aquel volumen, al recoger los resultados del descubrimiento de nuevos testimonios y de las últimas investigaciones sobre este ámbito, en lengua catalana, gallego-portuguesa y castellana de la Edad Media.

El artículo tiene como objetivo analizar la cobertura que los principales periódicos deportivos catalanes (Sport, Mundo Deportivo, El 9 Esportiu y Gol) hicieron de la campaña a la presidencia del FC Barcelona (Barça) de junio de 2010 y que acabó ganando Sandro Rosell. La investigación compara esta cobertura con la información de campaña aparecida en las redes sociales Twitter y Facebook usadas por cada candidatura y analiza si el uso de estas nuevas herramientas 2.0 influyó en la visibilidad de los candidatos en la prensa tradicional.

Many concepts have been developed to describe the convergence of media, languages, and formats in contemporary media systems. This article is a theoretical reflection on “transmedia storytelling” from a perspective that integrates semiotics and narratology in the context of media studies. After dealing with the conceptual chaos around transmedia storytelling, the article analyzes how these new multimodal narrative structures create different implicit consumers and construct a narrative world. The analysis includes a description of the multimedia textual structure created around the Fox television series 24. Finally, the article analyzes transmedia storytelling from the perspective of a semiotics of branding.

The emergence of social media has led many companies to adopt them as marketing channels. Yet these media are novel enough that many marketers are still unsure as to how to plan an effective social media marketing strategy, actually oriented towards engaging prospects. In this article, we discuss how to shape a social media strategy. To do so, we show the key concepts and steps involved in the planning process of this type of digital marketing strategy, and how to measure their impact immediately.

We present the implementation of dynamic electrostatic force microscopy in liquid media. This implementation enables the quantitative imaging of local dielectric properties of materials in electrolyte solutions with nanoscale spatial resolution. Local imaging capabilities are obtained by probing the frequency-dependent and ionic concentration-dependent electrostatic forces at high frequency (>1 MHz), while quantification of the interaction forces is obtained with finite-element numerical calculations. The results presented open a wide range of possibilities in a number of fields where the dielectric properties of materials need to be probed at the nanoscale and in a liquid environment.

We present new analytical tools able to predict the averaged behavior of fronts spreading through self-similar spatial systems starting from reaction-diffusion equations. The averaged speed for these fronts is predicted and compared with the predictions from a more general equation (proposed in a previous work of ours) and simulations. We focus here on two fractals, the Sierpinski gasket (SG) and the Koch curve (KC), for two reasons, i.e. i) they are widely known structures and ii) they are deterministic fractals, so the analytical study of them turns out to be more intuitive. These structures, despite their simplicity, let us observe several characteristics of fractal fronts. Finally, we discuss the usefulness and limitations of our approa

This article describes a literature review of the influence of advertising and the media on Eating Disorders (ED). Research published in scientific journals in various fields of social sciences such as sychology, psychiatry and communication science has enabled us to conclude that the content displayed in the media, including advertising, are enhancers of disorders and contribute significantly to body issatisfaction in relation to the perceived idea of beauty, it also facilitates the development of weight loss strategies in women and gain of muscle mass in men.

La evolución de peso en los períodos de lactación y transición de 583 lechones fue estudiada mediante un análisis estadístico, evaluando el efecto de la suplementación con ácidos grasos de cadena media (AGCM) en lechones con poco peso al nacimiento. 188 de los 375 lechones que nacieron con un peso al nacimiento (PN) <1250 g recibieron 3mL de AGCM cada 24 h durante los primeros 3 días de vida; su peso medio al destete (día 28) fue inferior respecto al grupo control (lechones no suplementados) (-114,17 g). No obstante, 106 de los 180 lechones nacidos con un PN <1000 g fueron suplementados, y su peso medio al destete y a finales de transición (día 63) fue superior respecto al grupo control (destete: +315,16 g; día 63: +775,47 g). Finalmente, los lechones suplementados con PN<800 g tuvieron los peores resultados: su diferencia de peso medio al destete fue de -177,58 g respecto al grupo control. Por lo tanto, en esta prueba fueron estudiados los lechones con un PN entre 800 y 999 g porque el grupo suplementado al destete tuvo una diferencia de peso medio considerable respecto al grupo control:+511,58 g. Asimismo, considerando una probabilidad de error inferior a 0,05, no hubieron diferencias significativas en las diferentes categorías de PN analizadas. De todas maneras, es importante destacar el alto grado de significación en la suplementación con AGCM en lechones con PN entre 800 y 999g (P=0,059). Por otra parte, el PN del grupo suplementado con PN<1000 g fue inferior que el del grupo no suplementado con PN<1000 g; esta diferencia de PN fue significativa (P=0,004) y como consecuencia el grado de significación en la suplementación con AGCM en lechones con PN entre 800 y 999 g fue inferior al esperado. Además, en esta prueba se incluyeron algunos resultados generales y también un análisis simple de supervivencia, aunque no era el objetivo principal

In a more transparent and dynamic world, in which consumers trust other consumers more for advice and recommendations on products and services, the continuity of organizations appears to be associated with socialization, the sharing of interests and the interaction with the audience. This is associated with the incorporation of digital technologies to business, specifically the use of social media. Consequently, it is timely and interesting to explore the phenomenon of virtual socialization, although it is a littlestudied field and what is needed is an innovative and theoretical approach based upon theories of marketing and communication. Expertise in these areas is present in all organizations and their performance is important for appropriate development of them. This work is a qualitative analysis about the behavior, reactions and attitudes of individuals to organizations, in order to understand the social factors that contribute to sustainable competitive advantages of organizations which can support strategic and future actions. We conclude that relevant factors associated with the tacit knowledge of the organization, specifically to learning and social interaction of the organization and their knowledge of virtual communities. The higher the coexistence of factors, the more difficult is the replication and greater will be the hypothesis of sustainable competitive advantage.
