Publiradio.net: innovación docente e investigación sobre publicidad radiofónica en el marco del EEES

La adaptación del sistema universitario catalán y español al Espacio Europeo de Educación Superior (EEES) está favoreciendo la aparición de nuevas metodologías docentes en respuesta a los requerimientos del llamado European Credit Transfer System (ECTS), una modalidad de crédito cuya principal característica consiste, como ya es ampliamente conocido, en focalizar la atención en el estudiante y, especialmente, en generar un proceso interactivo en el que el alumno se convierta en responsable activo de la adquisición de conocimientos. En el ámbito de las Ciencias de la Comunicación, una de las iniciativas más destacables de aproximación al EEES comienza en el año 2004, cuando el Departament d'Universitats, Investigació i Societat de la Informació de la Generalitat de Catalunya (DURSI) eligió a varios centros catalanes para que aplicaran de manera experimental el nuevo sistema común de créditos derivados de la Declaración de Bolonia. La Universidad Autónoma de Barcelona (UAB) fue uno de ellos, y ésta, a su vez, decidió poner en práctica la prueba piloto en la licenciatura de Publicidad y Relaciones Públicas. Es a partir de ese momento cuando los profesores del Departament de Comunicació Audiovisual i Publicitat de la UAB que forman el grupo de investigación Publiradio2 deciden poner en marcha un proyecto que, en el marco de las asignaturas de creatividad y de radio publicitaria, respondiera a las exigencias de la cultura docente en la que se inspira el crédito ECTS. Nace así Publiradio.net, un aplicativo on-line para la creación de publicidad radiofónica destinado, también, a facilitar y potenciar el aprendizaje autónomo entre los estudiantes, a fomentar, en sintonía con las apreciaciones de Aguaded, la utilización de 'técnicas y procedimientos que permitan al alumnado su análisis y uso como lenguajes propios' y a impulsar y facilitar a los estudiantes la investigación en publicidad radiofónica.

La ópera como integración de las artes : LSP 3.1

Embarcarse en la aventura de componer una ópera y llegar a materializarla con los mínimos recursos requiere de mucha imaginación e ilusión, de un trabajo constante y meditado, de un buen equipo de colaboradores, de fe ciega en que todo acabará funcionando y de lo más básico: un buen libreto. La serva padrona de Pergolesi nos demuestra cómo una historia sencilla y de recursos austeros puede llegar a ser tan tremendamente fresca, divertida y entretenida. Este intermezzo representará el punto de partida de una creación en la que la escena teatral y el discurso musical se fundirán de manera indivisible. Al fin y al cabo, la creación de una ópera supone asimilar desde buen principio que en ella convergen diferentes artes de índole muy diversa. Conseguir trabajar dentro de este marco de encuentro multidisciplinar es un privilegio que, sin duda, se debe aprovechar.

Deciding where to belong: gender differences in educational trajectories and migration in a rural Spanish town

From an anthropological perspective, formal post-secondary schooling is not an abstractentity with an intrinsic value that everyone finds desirable, but rather one alternative among many that young people evaluate from their different positions in the social field. The problem discussed in this paper is the diverging life trajectories that young men and women in a concrete rural context, at the end of the 20th century, shape for themselves at the ages of 14-16, a moment of decision created by national legislation regarding mandatory education (LGE, 1970, General Education Law, and LOGSE, 1990, General Organic Law of the Education System). Despite a strong cultural norm of equal inheritance divided among all children, male and female, and despite the equal educational opportunities provided by the Spanish State, different meanings of possession and use-rights over land and the resulting culturally accepted gendered division of work converge to orient men and women differently towards post-secondary schooling. Observation of the age, gender, and civil status structure of the population led to the preliminary query: Why do men and women, in this town, behave differently with respect to migration and marriage? The main hypothesis was that women’s longer school trajectories and resulting migration and men’s anchoring in the town and their higher rates of celibacy were not drastic changes in values, in the positional-relational sense of Bourdieu (1988, 2002), but the current outcome of previously existing dissimilar relations to property that produce dissimilar mobility. Through their schooling and work choices, young men and women, at very early ages, locate themselves in, or decide to belong to, different contexts that later reveal very different possibilities of finding marriage partners. This paper is based on an ethnographic study of a small rural town (302 inhabitants in 1950; 193 in 2000) near Leon. Although this paper deals with the situation in the final decades of the 20th century, we must also consider the first half of the century, where some elements that shape this situation have their roots. Fieldwork was carried out between 1988 and 2001, in periods of differing length and intensity. The social subjects discussed here are the domestic unit and its component members. They were studied in conjunction, analyzing the life-trajectory decisions of specific persons in the framework of the domestic unit and the relations among people and property which comprise it. The tried-and-true methods of ethnographic research –participant observation, interviews, and life-histories, etc.- were employed. Archival research was also important for producing demographic data. Demographic analysis, the analysis of the composition and transformation of domestic units, and the creation of life trajectories were among the principal techniques used. The theoretical analysis was oriented by Bourdieu’s (2002) framework of the social field, habitus, and difference.

Increased alpha-defensins 1-3 production by dendritic cells in HIV-infected individuals is associated with slower disease progression.

Defensins are natural endogenous antimicrobial peptides with potent anti-HIV activity and immuno-modulatory effects. We recently demonstrated that immature dendritic cells (DC) produce α-defensins1-3 and that α-defensins1-3 modulate DC generation and maturation. Since DC-HIV interaction plays a critical role during the first steps of HIV infection, we investigated the possible impact of α-defensins1-3 production by DC on disease progression.

Impact of community structure on information transfer

The observation that real complex networks have internal structure has important implication for dynamic processes occurring on such topologies. Here we investigate the impact of community structure on a model of information transfer able to deal with both search and congestion simultaneously. We show that networks with fuzzy community structure are more efficient in terms of packet delivery than those with pronounced community structure. We also propose an alternative packet routing algorithm which takes advantage of the knowledge of communities to improve information transfer and show that in the context of the model an intermediate level of community structure is optimal. Finally, we show that in a hierarchical network setting, providing knowledge of communities at the level of highest modularity will improve network capacity by the largest amount.

Comunidades bentonicas del sustrato duro del litoral NE Español, XIII. Vegetacion: diversidad y sociabilidad

A partir de los datos obtenidos en el estudio bionómico del bentos de la costa catalana, exponemos los correspondientes a la vegetación marina. Se comparan los índices de diversidad de las localidades de muestreo en relación con el espacio, la profundidad y las estaciones del año, relacionándolo con el número de especies de Clorófitos, Feófitos y Rodófitos que se han hallado en las muestras estudiadas. Con los valores de las afinidades entre las especies de mayor frecuencia de aparición se ha confeccionado un diagrama, donde aparecen varios grupos de algas que forman comunidades bastante características en algunas localidades de la costa catalana.

Heterogeneity and event dependence in the analysis of sickness absence

Sickness absence (SA) is an important social, economic and public health issue. Identifying and understanding the determinants, whether biological, regulatory or, health services-related, of variability in SA duration is essential for better management of SA. The conditional frailty model (CFM) is useful when repeated SA events occur within the same individual, as it allows simultaneous analysis of event dependence and heterogeneity due to unknown, unmeasured, or unmeasurable factors. However, its use may encounter computational limitations when applied to very large data sets, as may frequently occur in the analysis of SA duration. To overcome the computational issue, we propose a Poisson-based conditional frailty model (CFPM) for repeated SA events that accounts for both event dependence and heterogeneity. To demonstrate the usefulness of the model proposed in the SA duration context, we used data from all non-work-related SA episodes that occurred in Catalonia (Spain) in 2007, initiated by either a diagnosis of neoplasm or mental and behavioral disorders. As expected, the CFPM results were very similar to those of the CFM for both diagnosis groups. The CPU time for the CFPM was substantially shorter than the CFM. The CFPM is an suitable alternative to the CFM in survival analysis with recurrent events,especially with large databases.

Anàlisi lingüística d'un procés judicial de Mallorca del començament del segle XV

Aquest treball és l'anàlisi lingüística diacrònica d'un procés judicial sobre proxenetisme celebrat entre el mes de desembre de 1403 i el mes d'abril de 1404 a Binissalem (Mallorca). L'interès per la llengua no literària dels textos catalans medievals n'és el seu l'origen. L'estudi que presentam s'ha dividit en diferents seccions en què analitzam els nivells lingüístics (grafies i fonètica, morfosintaxi i lèxic). Els resultats aconseguits ens han permès confirmar i aportar més informació sobre l'estat de la llengua a la Mallorca medieval, entre els quals destacam alguns trets innovadors que detallam a l'anàlisi
