What movie will I watch today? The role of online review ratings, reviewers’ comments, and user’s gratification style

Browsing online ratings and viewers’ comments is an integral part of the experience of choosing and watching a movie. Current theories have broadened the concept of entertainment beyond amusement (hedonic motives) to include experiences of meaning, value, and self-development (eudaimonic motives). With a between-subjects design, we examined the role of the reviewer’s rating (medium rating vs high rating), comments (hedonic vs. eudaimonic), and participant’s gratification style on their interest in watching a movie. Results showed that participants (N = 383) reported a higher preference for the high rating movie. Results also revealed a match between comment type and individual gratification style, with participants with hedonic motives reporting more interest in the movie with hedonic comments, and those reporting eudaimonic motives for the movie with eudaimonic comments.info:eu-repo/semantics/acceptedVersio

A Meta-Analysis of Procedures to Change Implicit Measures

Using a novel technique known as network meta-analysis, we synthesized evidence from 492 studies (87,418 participants) to investigate the effectiveness of procedures in changing implicit measures, which we define as response biases on implicit tasks. We also evaluated these procedures’ effects on explicit and behavioral measures. We found that implicit measures can be changed, but effects are often relatively weak (|ds| \u3c .30). Most studies focused on producing short-term changes with brief, single-session manipulations. Procedures that associate sets of concepts, invoke goals or motivations, or tax mental resources changed implicit measures the most, whereas procedures that induced threat, affirmation, or specific moods/emotions changed implicit measures the least. Bias tests suggested that implicit effects could be inflated relative to their true population values. Procedures changed explicit measures less consistently and to a smaller degree than implicit measures and generally produced trivial changes in behavior. Finally, changes in implicit measures did not mediate changes in explicit measures or behavior. Our findings suggest that changes in implicit measures are possible, but those changes do not necessarily translate into changes in explicit measures or behavior

Computing point-of-view : modeling and simulating judgments of taste

Thesis (Ph. D.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2006.Includes bibliographical references (p. 153-163).People have rich points-of-view that afford them the ability to judge the aesthetics of people, things, and everyday happenstance; yet viewpoint has an ineffable quality that is hard to articulate in words, let alone capture in computer models. Inspired by cultural theories of taste and identity, this thesis explores end-to-end computational modeling of people's tastes-from model acquisition, to generalization, to application- under various realms. Five aesthetical realms are considered-cultural taste, attitudes, ways of perceiving, taste for food, and sense-of-humor. A person's model is acquired by reading her personal texts, such as a weblog diary, a social network profile, or emails. To generalize a person model, methods such as spreading activation, analogy, and imprimer supplementation are applied to semantic resources and search spaces mined from cultural corpora. Once a generalized model is achieved, a person's tastes are brought to life through perspective-based applications, which afford the exploration of someone else's perspective through interactivity and play. The thesis describes model acquisition systems implemented for each of the five aesthetical realms.(cont.) The techniques of 'reading for affective themes' (RATE), and 'culture mining' are described, along with their enabling technologies, which are commonsense reasoning and textual affect analysis. Finally, six perspective-based applications were implemented to illuminate a range of real-world beneficiaries to person modeling-virtual mentoring, self-reflection, and deep customization.by Xinyu Hugo Liu.Ph.D

Individualisation avancée des services IPTV

Le monde de la TV est en cours de transformation de la télévision analogique à la télévision numérique, qui est capable de diffuser du contenu de haute qualité, offrir aux consommateurs davantage de choix, et rendre l'expérience de visualisation plus interactive. IPTV (Internet Protocol TV) présente une révolution dans la télévision numérique dans lequel les services de télévision numérique sont fournis aux utilisateurs en utilisant le protocole Internet (IP) au dessus d une connexion haut débit. Les progrès de la technologie IPTV permettra donc un nouveau modèle de fourniture de services. Les fonctions offertes aux utilisateurs leur permettent de plus en plus d autonomie et de plus en plus de choix. Il en est notamment ainsi de services de type nTS (pour network Time Shifting en anglais) qui permettent à un utilisateur de visionner un programme de télévision en décalage par rapport à sa programmation de diffusion, ou encore des services de type nPVR (pour network Personal Video Recorder en anglais) qui permettent d enregistrer au niveau du réseau un contenu numérique pour un utilisateur. D'autre part, l'architecture IMS proposée dans NGN fournit une architecture commune pour les services IPTV. Malgré les progrès rapides de la technologie de télévision interactive (comprenant notamment les technologies IPTV et NGN), la personnalisation de services IPTV en est encore à ses débuts. De nos jours, la personnalisation des services IPTV se limite principalement à la recommandation de contenus et à la publicité ciblée. Ces services ne sont donc pas complètement centrés sur l utilisateur, alors que choisir manuellement les canaux de diffusion et les publicités désirées peut représenter une gêne pour l utilisateur. L adaptation des contenus numériques en fonction de la capacité des réseaux et des dispositifs utilisés n est pas encore prise en compte dans les implémentations actuelles. Avec le développement des technologies numériques, les utilisateurs sont amenés à regarder la télévision non seulement sur des postes de télévision, mais également sur des smart phones, des tablettes digitales, ou encore des PCs. En conséquence, personnaliser les contenus IPTV en fonction de l appareil utilisé pour regarder la télévision, en fonction des capacités du réseau et du contexte de l utilisateur représente un défi important. Cette thèse présente des solutions visant à améliorer la personnalisation de services IPTV à partir de trois aspects: 1) Nouvelle identification et authentification pour services IPTV. 2) Nouvelle architecture IPTV intégrée et comportant un système de sensibilité au contexte pour le service de personnalisation. 3) Nouveau service de recommandation de contenu en fonction des préférences de l utilisateur et aussi des informations contextesInternet Protocol TV (IPTV) delivers television content to users over IP-based network. Different from the traditional TV services, IPTV platforms provide users with large amount of multimedia contents with interactive and personalized services, including the targeted advertisement, on-demand content, personal video recorder, and so on. IPTV is promising since it allows to satisfy users experience and presents advanced entertainment services. On the other hand, the Next Generation Network (NGN) approach in allowing services convergence (through for instance coupling IPTV with the IP Multimedia Subsystem (IMS) architecture or NGN Non-IMS architecture) enhances users experience and allows for more services personalization. Although the rapid advancement in interactive TV technology (including IPTV and NGN technologies), services personalization is still in its infancy, lacking the real distinguish of each user in a unique manner, the consideration of the context of the user (who is this user, what is his preferences, his regional area, location, ..) and his environment (characteristics of the users devices screen types, size, supported resolution, and networks available network types to be used by the user, available bandwidth, .. ) as well as the context of the service itself (content type and description, available format HD/SD , available language, ..) in order to provide the adequate personalized content for each user. This advanced IPTV services allows services providers to promote new services and open new business opportunities and allows network operators to make better utilization of network resources through adapting the delivered content according to the available bandwidth and to better meet the QoE (Quality of Experience) of clients. This thesis focuses on enhanced personalization for IPTV services following a user-centric context-aware approach through providing solutions for: i) Users identification during IPTV service access through a unique and fine-grained manner (different from the identification of the subscription which is the usual current case) based on employing a personal identifier for each user which is a part of the user context information. ii) Context-Aware IPTV service through proposing a context-aware system on top of the IPTV architecture for gathering in a dynamic and real-time manner the different context information related to the user, devices, network and service. The context information is gathered throughout the whole IPTV delivery chain considering the user domain, network provider domain, and service/content provider domain. The proposed context-aware system allows monitoring user s environment (devices and networks status), interpreting user s requirements and making the user s interaction with the TV system dynamic and transparent. iii) Personalized recommendation and selection of IPTV content based on the different context information gathered and the personalization decision taken by the context-aware system (different from the current recommendation approach mainly based on matching content to users preferences) which in turn highly improves the users Quality of Experience (QoE) and enriching the offers of IPTV servicesEVRY-INT (912282302) / SudocSudocFranceF

Emotional responses to environmental messages: Implications for future environmentally responsible behavioral intentions

The present study analyzed the role of environmental message characteristics (message modality and message valence) and emotional arousal (positive and negative) in predicting environmentally responsible behavioral intentions. Using an experimental protocol designed to induce emotions in the laboratory, I measured specific emotional responses to gains-framed and losses-framed video and text-only environmental messages, and investigated the relation between intensity of emotional responses to environmental messages and environmentally responsible behavioral intentions. The sample consisted of 161 college students (116 women, 45 men). A hierarchical linear multiple regression was computed to assess the contributions of background variables (environmental knowledge, environmental beliefs, and outdoor recreational behavior), message modality and strength of emotional responses in predicting environmentally responsible behavioral intentions. Findings supported the overall model in explaining variance in environmentally responsible behavioral intentions. Results suggest that background variables, message modality, and negative emotional arousal significantly predicted environmentally responsible behavioral intention. Practical and theoretical implications are discussed

The Brazilian Telenovela El Clon : An Analysis of Viewers\u27 Online Vicarious and Virtual Learning Experiences

This research involves investigating Brazilian telenovelas as a medium to disseminate knowledge about different cultures and customs. Through a qualitative content analysis this study examines messages posted in the El Clon telenovela-world forum with reference to the Muslim cultural theme explored by the telenovela. The theoretical framework overarching this study is the combination of Bandura\u27s social learning/cognitive theory and Freire\u27s dialogical/participatory communication. In order to operationalize the study, a qualitative content analysis is undertaken utilizing the sub-dimension parasocial interaction model proposed by Sood & Rodgers (2000). The messages are analyzed in order to explore how forum participants engage in the discussion brought by the telenovela, in light of the proposed parasocial sub-dimensions: affective, cognitive, and behavioral interactions, and critical and referential involvement. The different opinions voiced and exchanged in the forum verify that the message writers think about the educational content of the novela, in the case of this study the portrayal of the Muslim culture, and the repercussion of this portrayal not only among the Muslim community but also the non-Muslim
