Television and the construction of identity: Barcelona, Olympic host

This document, originally published as part of the book The Keys of success: the social, sporting, economic and communications impact of Barcelona’92, comes from a larger study that looked at all aspects of television in the Olympics and can be found in its original version, in Miquel de Moragas Spà, Nancy K. Rivenburgh and James F. Larson (1996). Television in the Olympics. London: John Libbey.

Towards an emotion-driven interactive music system: ridging the gaps between affect, physiology and sound generation

Report for the scientific sojourn at the Stanford University from January until June 2007. Music is well known for affecting human emotional states, yet the relationship between specific musical parameters and emotional responses is still not clear. With the advent of new human-computer interaction (HCI) technologies, it is now possible to derive emotion-related information from physiological data and use it as an input to interactive music systems. Providing such implicit musical HCI will be highly relevant for a number of applications including music therapy, diagnosis, nteractive gaming, and physiologically-based musical instruments. A key question in such physiology-based compositions is how sound synthesis parameters can be mapped to emotional states of valence and arousal. We used both verbal and heart rate responses to evaluate the affective power of five musical parameters. Our results show that a significant correlation exists between heart rate and the subjective evaluation of well-defined musical parameters. Brightness and loudness showed to be arousing parameters on subjective scale while harmonicity and even partial attenuation factor resulted in heart rate changes typically associated to valence. This demonstrates that a rational approach to designing emotion-driven music systems for our public installations and music therapy applications is possible.

Parents, television and cultural change

This paper develops a model of cultural transmission where television plays a central role for socialization. Parents split their free time between educating their children which is costly and watching TV which though entertaining might socialize the children to the wrong trait. The free to air television industry maximizes advertisement revenue. We show that TV watching is increasing in cultural coverage, cost of education, TV's entertainment value and decreasing in the perceived cultural distance between the two traits. A monopolistic television industry captures all TV watching by both groups if the perceived cultural distance between groups is small relative to the TV's entertainment value. Otherwise, more coverage will be given to the most profitable group where profitability increases in group size, advertisement sensitivity and perceived cultural distance. This leads to two possible steady states where one group is larger but both groups survive in the long run. Competition in the media industry might lead to cultural extinction but only if one group is very insensitive to advertisement and not radical enough not to watch TV. We briefly discuss the existing evidence for the empirical predictions of the model.

El joc del TERCETI : una unitat didàctica multimèdia sobre GNU/LINUX amb suport DVB-MHP i SCORM.

Fent ús del programari lliure s'ha generat la unitat didàctica del joc del terceti per a la televisió digital interactiva i s'ha desada en format SCORM. La facilitat d'ús del comandament a distància fa possible practicar un tipus de t-learning fonamentat en l'edutainment (education+entertaiment) i provoca que el teleespectador passiu passi a ser un "teleusuari" més actiu.

The future of television : advertising, technology and the pursuit of audiences

La televisió està en crisi. Les noves tecnologies i els dispositius han fragmentat les audiències de televisió en segments més petits. En aquest informe, Marissa Gluck i Meritxell Roca Sales examinen l'explosió dels mitjans de comunicació que han impulsat aquesta fragmentació.

I-SS: integrated supervision systems approach based on interactive components

Process supervision is the activity focused on monitoring the process operation in order to deduce conditions to maintain the normality including when faults are present Depending on the number/distribution/heterogeneity of variables, behaviour situations, sub-processes, etc. from processes, human operators and engineers do not easily manipulate the information. This leads to the necessity of automation of supervision activities. Nevertheless, the difficulty to deal with the information complicates the design and development of software applications. We present an approach called "integrated supervision systems". It proposes multiple supervisors coordination to supervise multiple sub-processes whose interactions permit one to supervise the global process

The migration towards Digital Terrestrial Television: challenges for public policy and public broadcasters

This paper initially identifies the main transformations of the television system that are caused by digitalization. Its development in several broadcasting platforms is analyzed as well as the particular obstacles and requirements that are detected for each of them. Due to its technical characteristics and its historical link to the public services, the terrestrial network requires migration strategies different from those strictly commercial, and public intervention might be needed. The paper focuses on such migration strategies towards DTT and identifies the main issues for public intervention in the areas of the digital scenario: technology, business and market transformation and the reception field. Moreover, it describes and classifies the challenges that public broadcasters should confront due to digitalization. This paper finally concludes that the leadership of the public broadcasters during the migration towards DTT is an interesting tool for public policy. The need for foster the digitalization of the terrestrial platform and to achieve certain social and public goal besides the market interest brings an opportunity for public institutions and public broadcasters to work together. That leading role could also be positive for the public service to face its necessary redefinition and reallocation within the digital context.

Dialogic learning and interactive groups: an IMS LD template integrated in runtime systems

Dialogic learning and interactive groups have proved to be a useful methodological approach appliedin educational situations for lifelong adult learners. The principles of this approach stress theimportance of dialogue and equal participation also when designing the training activities. This paperadopts these principles as the basis for a configurable template that can be integrated in runtimesystems. The template is formulated as a meta-UoL which can be interpreted by IMS Learning Designplayers. This template serves as a guide to flexibly select and edit the activities at runtime (on the fly).The meta-UoL has been used successfully by a practitioner so as to create a real-life example, withpositive and encouraging results

Implementing interactive computing in an object-oriented environment

Statistical computing when input/output is driven by a Graphical User Interface is considered. A proposal is made for automatic control ofcomputational flow to ensure that only strictly required computationsare actually carried on. The computational flow is modeled by a directed graph for implementation in any object-oriented programming language with symbolic manipulation capabilities. A complete implementation example is presented to compute and display frequency based piecewise linear density estimators such as histograms or frequency polygons.

Interactive local bandwidth choice

A tool for user choice of the local bandwidth function for a kernel density estimate is developed using KDE, a graphical object-oriented package for interactive kernel density estimation written in LISP-STAT. The bandwidth function is a cubic spline, whose knots are manipulated by the user in one window, while the resulting estimate appears in another window. A real data illustration of this method raises concerns, because an extremely large family of estimates is available.

El relato audiovisual publicitario del siglo XXI. Del medio televisión al medio internet. ¿Nuevos medios o nuevas formas de consumo audiovisual?

Estudiar la comunicación publicitaria del siglo XXI nos permite entender la importancia del desarrollo actual de este tipo de comunicación. Sin duda un desarrollo que afecta enormemente en el modo en que las marcas llevan a cabo sus estrategias de publicidad con su público. Pero sin duda el formato audiovisual sigue siendo el formato más utilizado por anunciantes y agencias para contactar con su público. El siglo XX estuvo definido por el desarrollo del medio televisión, el siglo XXI por el desarrollo del medio internet, pero la pregunta que realmente nos plantea este cambio mediático es conocer si estamos hablando de un cambio de medio o de un cambio en las estrategias y formatos publicitarios audiovisuales utilizados para llegar al receptor. Los mensajes publicitarios actuales resaltan por una mayor interactividad con el espectador, un contacto voluntario de éste, en muchos casos, con nuestra campaña e incluso una participación activa de nuestro consumidor en la distribución de la campaña. Los formatos evolucionan, también la relación del consumidor con el mensaje publicitario audiovisual y el producto

Corruption in building the image of politics in television news broadcasts

This work analyses the political news of eight Spanish television channels in order to see what image is built of politics, and particularly how the news of corruption affects the image of politics in Spanish news broadcasts. Different cases of corruption such as Gürtel, Palma Arena and those associated with judge Baltasar Garzón in his final stage in office, occupy part of the study. A new methodology is therefore proposed that enables the quality of the political information emitted from inside and outside the political content of the news programmes to be observed. Particular attention is paid to the news broadcasts of Televisión Española and Cuatro as those which offer a more balanced view of politics, and channels such as La Sexta, which give priority to a narrative construction of politics in the news programmes around causes of corruption.

Online brands: Branding, possible worlds, and interactive grammars

This paper proposes to reflect from a semiotic perspective on the transformation that brands have undergone since the rise of the Internet. After a brief theoretical introduction to digital communication and the semiotics of brands, the case of the Google brand is analyzed by applying concepts of generative and interpretive semiotics. The paper holds that the iconic and linguistic enunciations are secondary with respect to interaction. In digital media interaction — the interactive experience that the Internet user lives — is a fundamental component of the hypermedia cocktail and occupies a central position in the brand building process. The article concludes with some of the questions and special characteristics raised by so-called eBranding.
