Social networks as digital leisure spaces

Vivimos en una sociedad digital donde los hábitos y estilos de vida se han visto transformados debido al desarrollo de Internet y las nuevas Tecnologías de la Información y la Comunicación (TIC). El ocio, entendido en este artículo como experiencia de desarrollo humano (Cuenca, 2000) y ámbito vital, tampoco se ha resistido a la influencia de la tecnología y la esfera virtual, dando pie a la generación de nuevos ocios virtuales entre los que destaca el uso de las redes sociales. Son parte de las nuevas prácticas de ocio de los jóvenes españoles y los nuevos formatos de entretenimiento. Fundamentándonos en el modo de entender el ocio del Instituto de Estudios de ocio de la Universidad de Deusto y en la dicotomía de ocio serio y ocio casual defendida por Stebbins (2008), pretendemos dar respuesta a los siguientes planteamientos: ¿de qué manera ha influido la revolución digital en el ámbito del ocio?, ¿nos encontramos ante nuevos formatos de entretenimiento de carácter consumista o bien ante prácticas de ocio digital que fomentan el desarrollo personal? Esto nos llevará a analizar los usos que los jóvenes pertenecientes a la generación digital hacen de las redes sociales virtuales.We live in a digital society where habits and lifestyles have been transformed by the development of the Internet and New Technologies of Information and Communication (ICT). Leisure, understood in this article as an experience of human development (Cuenca, 2000) and vital area, neither has resisted the influence of technology and the virtual sphere, and that caused the generation of new virtual leisures, among which the most important is the use of social networks. They are part of the new leisure practices of Spanish young people and new entertainment formats. Based on the way of understanding the concept of leisure inherent to Institute of Leisure Studies of the University of Deusto and the dichotomy between of serious leisure and casual leisure defended by Stebbins (2008), we try to answer the following approaches: what way has influenced the digital revolution in the field of leisure?, are we faced with new practices of consumer entertainment formats or with digital leisure practices that promote personal development? This will lead us to analyze the uses that young people belonging to the digital generation made of virtual social networks

Connected, mobile, transmedia and multiformat leisure of youngs in the digi-tal age

El desarrollo constante de las tecnologías digitales ha transformado una gran parte de los ámbitos de actuación hu-mana, entre ellos, la esfera del ocio. Los jóvenes son uno de los colectivos que más han notado su influencia, ya que el ciberespacio se ha instaurado como un espacio de ocio al que recurren con frecuencia, más aún desde que los smartphones comenzaron a ser los principales dispositivos de acceso a Internet. El ocio de los jóvenes se define como un ocio conectado, móvil, transmedia y multisoporte. Estilos de ocio que emplean para informarse, comunicarse, pa-sar el rato y divertirse. Prácticas de ocio en red que interpretadas desde el paradigma del ocio casual vs. ocio serio o el nivel de apropiación de la tecnología son propias de un ocio superficial. Un e-ocio que pese a ser percibido por los propios jóvenes como positivo, no aprovecha todas las potencialidades que Internet ofrece.The constant development of digital technologies has become a large part of the areas of human performance, in-cluding the sphere of leisure. Young people are one of the collective that have most noticed his influence, since cy-berspace has established itself as a leisure space which often recur, even more so since smartphones began to be the main Internet access devices. Leisure of youth is defined as a leisure connected, mobile, and multi transmedia. Lei-sure styles they use to learn, communicate, hang out and have fun. Leisure practices networked interpreted from the paradigm leisure casual vs. serious leisure or level of appropriation of technology are characteristic of a superficial leisure. An e-leisure that, despite being perceived by young people themselves as positive, does not take full potential of the Internet

Filtering directory lookups in CMPs

Coherence protocols consume an important fraction of power to determine which coherence action should take place. In this paper we focus on CMPs with a shared cache and a directory-based coherence protocol implemented as a duplicate of local caches tags. We observe that a big fraction of directory lookups produce a miss since the block looked up is not cached in any local cache. We propose to add a filter before the directory lookup in order to reduce the number of lookups to this structure. The filter identifies whether the current block was last accessed as a data or as an instruction. With this information, looking up the whole directory can be avoided for most accesses. We evaluate the filter in a CMP with 8 in-order processors with 4 threads each and a memory hierarchy with a shared L2 cache.We show that a filter with a size of 3% of the tag array of the shared cache can avoid more than 70% of all comparisons performed by directory lookups with a performance loss of just 0.2% for SPLASH2 and 1.5% for Specweb2005. On average, the number of 15-bit comparisons avoided per cycle is 54 out of 77 for SPLASH2 and 29 out of 41 for Specweb2005. In both cases, the filter requires less than one read of 1 bit per cycle.Postprint (published version

Aplicación nativa ANDROID para la localización de autobuses más frecuentemente usados en Londres

Aunque existen distintas aplicaciones en el mercado que ofrecen todo tipo de información sobre los autobuses de la ciudad de Londres, facilitada por la “Transport For London Unified API”, éstas no se enfocan en usuarios de autobús cuya rutina les lleva a usar con frecuencia la misma línea de autobús que cogen en las mismas paradas. Esta aplicación, que he llamado buStop, pretende llenar ese hueco, ofreciendo de manera rápida y requiriendo la mínima interacción posible del usuario, la información que necesita, cuándo la necesita y por supuesto de forma segura y en tiempo real. Para el desarrollo del proyecto se han tratado de seguir los pasos lógicos y de la manera más real posible, que se habrían seguido para desarrollar un producto en un marco de trabajo moderno. Desde el desarrollo de un plan de proyecto que justificaría llevarlo a cabo, como la definición funcional y desarrollo del mismo. El empleo de los principios definidos en las metodologías ágiles, así como el empleo de la última arquitectura de componentes definida por Google para el desarrollo de aplicaciones Android han ayudado al autor a profundizar y ampliar conocimientos en áreas y tecnologías que se encontraban fuera del ámbito habitual de su trabajo

Identification of organoleptic and functional quality profiles in Spanish traditional cultivars of tomato

The original publication is available at www.actahort.orgDespite the increasing importance of the internal quality in breeding programmes and marketing of tomato, little information is available regarding organoleptic and functional profiles of traditional cultivars of renowned quality. The aim of this study is to evaluate the internal quality of 51 traditional tomato accessions representative of the Spanish genepool. Total soluble solids, oxalic, malic, citric and glutamic acids, fructose, glucose and sucrose, vitamin C and lycopene were determined, thereby obtaining the respective organoleptic and functional profiles. These profiles will be very valuable in establishing breeding objectives, to provide the cultivars appreciated by consumers, willing to pay higher prices for them. A considerable high level of variability has been found in the profiles obtained and no clear groups could be identified with regards to fruit morphology or local name. Variability was higher in those traits affecting functional quality (coefficients of variation of 51.2% for vitamin C and 74.6% for lycopene content) than those affecting organoleptic quality (coefficients of variation ranged from 18% for total soluble contents to 38.8% for glutamic acid). Additionally, several accessions were selected on the basis of their higher individual contents for further studies of internal quality. These accessions were CDP8102 and CDP3547 for high malic acid, accession CDP6315 for high fructose and glucose levels, accession CDP1523 for its lycopene content and accessions CDP2226 and CDP336 for high vitamin C content. Considering previous correlations between individual contents and consumer preference, accessions CDP7554, CDP2666 and CDP3547 should be further evaluated for their overall flavour quality.Cortés Olmos, C.; Leiva Brondo, M.; Adalid Martinez, AM.; Cebolla Cornejo, J.; Nuez Viñals, F.

Adaptación del sistema radicular de melón (Cucumis melo L.) frente a la deficiencia en fósforo

[ES] Los resultados demuestran la variabilidad, tanto en la arquitectura de raíz en condiciones normales, como en la respuesta plástica a la deficiencia en fósforo de las entradas de melón estudiadas. Las entradas de la subsp. agrestis, y algunos grupos botánicos de la subsp. melo con entradas más rústicas, como el tipo flexuosus y chate, muestran una respuesta muy marcada a la deficiencia en fósforo. Para los grupos de melones cultivados las tipologías de respuesta son más diversas, pero existe variación, tanto en el grupo inodorus como en el grupo cantalupensis y reticulatus, que resulta de interés para la mejora de los tipos cultivados.Los trabajos realizados han sido parcialmente financiados por el proyecto INIARF2008-00003-C02-02 y por el proyecto ERANETGEN2006-27773-C2-2.Fita, A.; Nuez Viñals, F.; Picó Sirvent, MB.

Root transcriptional responses of two melongenotypes with contrasting resistance toMonosporascus cannonballus (Pollack et Uecker)infection

Background: Monosporascus cannonballus is the main causal agent of melon vine decline disease. Several studies have been carried out mainly focused on the study of the penetration of this pathogen into melon roots, the evaluation of symptoms severity on infected roots, and screening assays for breeding programs. However, a detailed molecular view on the early interaction between M. cannonballus and melon roots in either susceptible or resistant genotypes is lacking. In the present study, we used a melon oligo-based microarray to investigate the gene expression responses of two melon genotypes, Cucumis melo ¿Piel de sapo¿ (¿PS¿) and C. melo ¿Pat 81¿, with contrasting resistance to the disease. This study was carried out at 1 and 3 days after infection (DPI) by M. cannonballus. Results: Our results indicate a dissimilar behavior of the susceptible vs. the resistant genotypes from 1 to 3 DPI. ¿PS¿ responded with a more rapid infection response than ¿Pat 81¿ at 1 DPI. At 3 DPI the total number of differentially expressed genes identified in ¿PS¿ declined from 451 to 359, while the total number of differentially expressed transcripts in ¿Pat 81¿ increased from 187 to 849. Several deregulated transcripts coded for components of Ca2+ and jasmonic acid (JA) signalling pathways, as well as for other proteins related to defence mechanisms. Transcriptional differences in the activation of the JA-mediated response in ¿Pat 81¿ compared to ¿PS¿ suggested that JA response might be partially responsible for their observed differences in resistance. Conclusions: As a result of this study we have identified for the first time a set of candidate genes involved in the root response to the infection of the pathogen causing melon vine decline. This information is useful for understanding the disease progression and resistance mechanisms few days after inoculation.Roig Montaner, MC.; Fita, A.; Rios, G.; Hammond, JP.; Nuez Viñals, F.; Picó Sirvent, MB.

Stress-related coping styles, anxiety, and neuroticism in university students with myalgia temporomandibular: A case control study

Los pacientes que sufren dolor debido a trastornos temporomandibulares (TTM) presentan mayores niveles de distrés psicológico, estrés ambiental, síntomas somáticos, ansiedad, depresion, cogniciones de catastrofización, y otras estrategias de afrontamiento al dolor alteradas, comparados con personas libres de dolor. Sin embargo, poco se conoce acerca de los factores psicológicos involucrados en diferentes tipos de TTM. Además, independientemente de la gravedad o el tipo de TTM, el papel de los estilos y estrategias de afrontamiento al estrés en los TTM todavía no está claro. El principal objetivo de este trabajo es estudiar los estilos de afrontamiento al estrés, ansiedad y rasgos de personalidad en un grupo de estudiantes de odontología que sufren mialgia temporomandibular. Una muestra de 102 estudiantes universitarios fue inicialmente reclutada para este estudio. Tras una evaluación clínica, se formaron un grupo de estudiantes con mialgia (24 participantes) y un grupo de estudiantes control (24 participantes). Los participantes de ambos grupos fueron posteriormente evaluados en ansiedad, estrategias de afrontamiento al estrés, y rasgos de personalidad. El grupo con mialgia mostró mayor rasgo de ansiedad y neuroticismo que el grupo control. Los participantes con mialgia también mostraron un mayor uso de estrategias de afrontamiento evitativas. Las estrategias evitativas generalmente se han considerado como desadaptativas, y se ha visto que incrementan el estrés percibido, un fuerte predictor de TTM.Patients suffering pain-related temporomandibular disorders (TMD) exhibit greater levels of psychological distress, environmental stress, somatic symptoms, anxiety, depression, pain catastrophizing, and impaired pain coping strategies compared to pain-free controls. However, little is known about psychological factors involved in the different TMD types. Furthermore, regardless of severity or TMD type, the role of stress-related coping strategies and styles in TMD is not yet well understood. The main goal of this study was to investigate stress-related coping styles, anxiety, and personality traits in a group of dentistry students suffering from temporomandibular disorder with myalgia. A cohort of 102 university students was initially recruited for this study. Following clinical evaluation, a myalgia group (24 participants) and a control group (25 participants) were formed. Participants were later assessed in anxiety, stress coping strategies, and personality measures. The myalgia group presented greater levels of trait anxiety and neuroticism in comparison to the control group. Participants with myalgia also showed higher levels of avoidance coping. Avoidance coping strategies are generally considered maladaptive, as they seem to increase perceived stress, a robust predictor of TM
