TV Advertisement and the clever audience

Els anuncis televisius –i els mitjans publicitaris en general– tenen entre els seus propòsits els de captar l’atenció dels espectadors i arribar a una audiència de consumidors potencials. Aquestes dues finalitats no acostumen a representar processos separats o nivells de percepció diferents per part de l’espectador: si l’anunci assoleix la seva meta, despertarà un interès que serà l’interès d’aquells que es considera que tenen més probabilitats de comprar el producte o de realitzar l’acció que l’anunci vol promoure. Com més gran sigui la precisió a l’hora d’establir contacte amb aquestes persones, més específic, directe i, en conseqüència, reeixit, serà l’efecte del missatge. Pot semblar una paradoxa el fet que un dels procediments utilitzats per a atraure l’atenció de l’audiència sigui presentar un anunci el significat del qual no s’entén a primera vista. Però es tracta d’un recurs útil. La percepció d’alguns anuncis és semblant a la que es produeix al llegir poemes o certs relats curts, tenim la tendència a rellegir-los. Potser en una primera lectura no acabem de copsar-ne el significat, però això mateix es converteix en un repte que ens porta a llegir-lo una i altra vegada fins que descobrim el missatge del text. Quan arribem a aquest punt, l’esforç esdevé plaer estètic i el filtre que selecciona l’audiència també serveix per a seleccionar el client potencial.

Competition between TV platforms

The aim of this paper is to identify the factors that affect the market penetration of pay television by studying the competition that exists between three types of technology (satellite, cable and ADSL). We distinguish three groups of factors: the level of market competition, the level of competition in the industry and the quality of the product being offered. Our results seem to indicate that as market concentration increases, the television service can achieve greater penetration. This relationship is specifically captured by the level of intra- and inter-platform competition. We also examine the relationship between free television channels and pay television and find that as the amount of time dedicated to the broadcasting of advertising by the former increases, the number of subscribers to pay TV rises. Finally, we examine product quality by introducing the effect of holding the rights to broadcast Professional Football League matches and an HBO or Showtime produced series. Our results suggest that these variables are critical for the penetration of pay television.

El reporterismo de investigación en el medio televisivo: del reportero neutro, al declarado, pasando por el discreto (Análisis de Documentos TV, A la presó y 21 días)

El treball final de carrera analitza el reporterisme d'investigació en el mitjà televisiu, un dels fenòmens que actualment, en la pràctica periodística, s'està posant cada vegada més de moda. Per aquest motiu s'ha realitzat una part teòrica amb l'objectiu de sintetitzar tot el que fa referència al marc conceptual, des dels seus inicis, fins els elements que ho componen i que formen part del procés d'investigació i, posteriorment, una part pràctica on s'ha efectuat una anàlisi de diferents reportatges actuals d'investigació televisius. La conclusió del treball demostra que les noves audiències són les protagonistes que el panorama del reporterisme televisiu estigui evolucionant cap a nous formats, formats que, al mateix temps que progressen, conviuen els uns amb els altres dins la mateixa graella televisiva.

Towards smart user models in open environments

Our work is concerned with user modelling in open environments. Our proposal then is the line of contributions to the advances on user modelling in open environments thanks so the Agent Technology, in what has been called Smart User Model. Our research contains a holistic study of User Modelling in several research areas related to users. We have developed a conceptualization of User Modelling by means of examples from a broad range of research areas with the aim of improving our understanding of user modelling and its role in the next generation of open and distributed service environments. This report is organized as follow: In chapter 1 we introduce our motivation and objectives. Then in chapters 2, 3, 4 and 5 we provide the state-of-the-art on user modelling. In chapter 2, we give the main definitions of elements described in the report. In chapter 3, we present an historical perspective on user models. In chapter 4 we provide a review of user models from the perspective of different research areas, with special emphasis on the give-and-take relationship between Agent Technology and user modelling. In chapter 5, we describe the main challenges that, from our point of view, need to be tackled by researchers wanting to contribute to advances in user modelling. From the study of the state-of-the-art follows an exploratory work in chapter 6. We define a SUM and a methodology to deal with it. We also present some cases study in order to illustrate the methodology. Finally, we present the thesis proposal to continue the work, together with its corresponding work scheduling and temporalisation

Under-achievement and the glass ceiling: Evidence from a TV game show

We use a Colombian TV game show to test gender differences in competitivebehavior where there is no opportunity for discrimination and females face no genderspecificexternal constraints. Each game started with six contestants who had toanswer general knowledge questions in private. There were five rounds of questionsand, at the end of each, one participant was eliminated. Despite equality in startingnumbers, women earn less than men and exit the game at a faster rate. In particular,there are more voluntary withdrawals by women than men. We draw an analogybetween the game and the process by which employees rise through the levels of acorporation. As such, we note that glass ceilings may result, in part, from women sown behavior and this raises the issue of how women are socialized to behave. At thesame time, our results illustrate that maintaining and promoting gender diversity at thelower/middle ranks of organizations is necessary to obtain gender diversity at the top.

TV or not TV? Subtitling and English skills

We study the influence of television translation techniques on the quality of the English spoken across the EU and OCDE. We identify a large positive effect for subtitled original version as opposed to dubbed television, which loosely corresponds to between four and twenty years of compulsory English education at school. We also show that the importance of subtitled television is robust to a wide array of specifications.We then find that subtitling and better English skills have an influence on high-tech exports, international student mobility, and other economic and social outcomes.

A reusable smart interface for gas sensor resistance measurement

The advances of the semiconductor industry enable microelectromechanical systems sensors, signal conditioning logic and network access to be integrated into a smart sensor node. In this framework, a mixed-mode interface circuit for monolithically integrated gas sensor arrays was developed with high-level design techniques. This interface system includes analog electronics for inspection of up to four sensor arrays and digital logic for smart control and data communication. Although different design methodologies were used in the conception of the complete circuit, high-level synthesis tools and methodologies were crucial in speeding up the whole design cycle, enhancing reusability for future applications and producing a flexible and robust component.

Application of a floating well concept to a latch-up-free, low-cost, smart power high-side switch technology

The aim of this brief is to present an original design methodology that permits implementing latch-up-free smart power circuits on a very simple, cost-effective technology. The basic concept used for this purpose is letting float the wells of the MOS transistors most susceptible to initiate latch-up.

Smart antennas in software radio base stations

The application of adaptive antenna techniques to fixed-architecture base stations has been shown to offer wide-ranging benefits, including interference rejection capabilities or increased coverage and spectral efficiency.Unfortunately, the actual implementation ofthese techniques to mobile communication scenarios has traditionally been set back by two fundamental reasons. On one hand, the lack of flexibility of current transceiver architectures does not allow for the introduction of advanced add-on functionalities. On the other hand, theoften oversimplified models for the spatiotemporal characteristics of the radio communications channel generally give rise toperformance predictions that are, in practice, too optimistic. The advent of software radio architectures represents a big step toward theintroduction of advanced receive/transmitcapabilities. Thanks to their inherent flexibilityand robustness, software radio architecturesare the appropriate enabling technology for theimplementation of array processing techniques.Moreover, given the exponential progression ofcommunication standards in coexistence andtheir constant evolution, software reconfigurabilitywill probably soon become the only costefficientalternative for the transceiverupgrade. This article analyzes the requirementsfor the introduction of software radio techniquesand array processing architectures inmultistandard scenarios. It basically summarizesthe conclusions and results obtained withinthe ACTS project SUNBEAM,1 proposingalgorithms and analyzing the feasibility ofimplementation of innovative and softwarereconfigurablearray processing architectures inmultistandard settings.
