The Impact of a Character Posture Model on the Communication of Affect in an Immersive Virtual Environment

This paper presents the quantitative and qualitative findings from an experiment designed to evaluate a developing model of affective postures for full-body virtual characters in immersive virtual environments (IVEs). Forty-nine participants were each requested to explore a virtual environment by asking two virtual characters for instructions. The participants used a CAVE-like system to explore the environment. Participant responses and their impression of the virtual characters were evaluated through a wide variety of both quantitative and qualitative methods. Combining a controlled experimental approach with various data-collection methods provided a number of advantages such as providing a reason to the quantitative results. The quantitative results indicate that posture plays an important role in the communication of affect by virtual characters. The qualitative findings indicated that participants attribute a variety of psychological states to the behavioral cues displayed by virtual characters. In addition, participants tended to interpret the social context portrayed by the virtual characters in a holistic manner. This suggests that one aspect of the virtual scene colors the perception of the whole social context portrayed by the virtual characters. We conclude by discussing the importance of designing holistically congruent virtual characters especially in immersive settings.

Use of social networks for academic purposes: a case study

Purpose- This paper aims to analyse various aspects of an academic social network: the profile of users, the reasons for its use, its perceived benefits and the use of other social media for scholarly purposes. Design/methodology/approach- The authors examined the profiles of the users of an academic social network. The users were affiliated with 12 universities. The following were recorded for each user: sex, the number of documents uploaded, the number of followers, and the number of people being followed. In addition, a survey was sent to the individuals who had an email address in their profile. Findings- Half of the users of the social network were academics and a third were PhD students. Social sciences scholars accounted for nearly half of all users. Academics used the service to get in touch with other scholars, disseminate research results and follow other scholars. Other widely employed social media included citation indexes, document creation, edition and sharing tools and communication tools. Users complained about the lack of support for the utilisation of these tools. Research limitations/implications- The results are based on a single case study. Originality/value- This study provides new insights on the impact of social media in academic contexts by analysing the user profiles and benefits of a social network service that is specifically targeted at the academic community.

Políticas universitarias de difusión de la información a través de la propia web institucional

La difusión de la información se ha convertido en uno de los elementos críticos en los planes estratégicos de las instituciones universitarias. Inquietadas por su posición en los rankings internacionales que evalúan este tipo de instituciones, las universidades comienzan a preocuparse también por sus estrategias de difusión de información y sus webs institucionales. En este trabajo se abordan las funciones principales de las webs universitarias; el proceso de análisis, diseño e implementación en la creación de este tipo de sitios webs; los elementos mínimos que deben incluirse en una guía de estilo de web universitaria; y algunos de los principales estándares y referencias nacionales e internacionales de ese tipo de guías.

Aprendizaje Servicio Universitario: creando empleo a partir de la emprendeduría social

La Universidad debe erigirse como motor de la sociedad civil y abordar con decisión los desafíos sociales contemporáneos, como es la situación de paro en España. La metodología del Aprendizaje Servicio Universitario permite integrar un aprendizaje basado en la realidad con el servicio a la comunidad concretizando la responsabilidad social de la Universidad. El artículo presenta el proyecto interfacultativo EcoSPORTech desarrollado en la Universidad de Vic cuya finalidad ha sido la creación de empleo juvenil desde la emprendeduría social. La política de comunicación ha sido clave en este proyecto.
