The development of broadband Internet connections has fostered new audiovisual media services and opened new possibilities for accessing broadcasts. The Internet retransmission case of TVCatchup before the CJEU was the first case concerning new technologies in the light of Art. 3.1. of the Information Society Directive. On the other side of the Atlantic the Aereo case reached the U.S. Supreme Court and challenged the interpretation of public performance rights. In both cases the recipients of the services could receive broadcast programs in a way alternative to traditional broadcasting channels including terrestrial broadcasting or cable transmission. The Aereo case raised the debate on the possible impact of the interpretation of copyright law in the context of the development of new technologies, particularly cloud based services. It is interesting to see whether any similar problems occur in the EU. The „umbrella” in the title refers to Art. 8 WCT, which covers digital and Internet transmission and constitutes the backrgound for the EU and the U.S. legal solutions. The article argues that no international standard for qualification of the discussed services exists.

De nos jours, les séries télévisées américaines représentent une part incontournable de la culture populaire, à tel point que plusieurs traductions audiovisuelles coexistent au sein de la francophonie. Outre le doublage qui permet leur diffusion à la télévision, elles peuvent être sous titrées jusqu’à trois fois soit, en ordre chronologique : par des fans sur Internet; au Québec, pour la vente sur DVD en Amérique du Nord; et en France, pour la vente sur DVD en Europe. Pourtant, bien que ces trois sous titrages répondent aux mêmes contraintes linguistiques (celles de la langue française) et techniques (diffusion au petit écran), ils diffèrent dans leur traitement des dialogues originaux. Nous établissons dans un premier temps les pratiques à l’œuvre auprès des professionnels et des amateurs. Par la suite, l’analyse des traductions ainsi que le recours à un corpus comparable de séries télévisées françaises et québécoises permettent d’établir les normes linguistiques (notamment eu égard à la variété) et culturelles appliquées par les différents traducteurs et, subsidiairement, de définir ce que cache l’appellation « Canadian French ». Cette thèse s’inscrit dans le cadre des études descriptives et sociologiques. Nous y décrivons la réalité professionnelle des traducteurs de l’audiovisuel et l’influence que les fansubbers exercent non seulement sur la pratique professionnelle, mais aussi sur de nouvelles méthodes de formation de la prochaine génération de traducteurs. Par ailleurs, en étudiant plusieurs traductions d’une même œuvre, nous démontrons que les variétés de français ne sauraient justifier, à elles seules, la multiplication de l’offre en sous titrage, vu le faible taux de différences purement linguistiques.

Design for visors for the delegation from Jamaica to the London Olympic Games 2012. This design was commissioned by PUMA 2012 based on McLean's designs featured in the website House of Flora, which functions as a space of display, archive, folio, point of sale and dissemination. The McLean standard design for visors is a component of the avant garde, pret a porter millinery, accessory design collections, and stylistically customised for the Jamaican team. McLean's oeuvre is original in its integration of the experimental traditions of art school workshop culture with the professional demands of fashion manufacture and trade culture. Combining the innovation of the postmodern urban artisan with the exacting demands of industrial production, dissemination and distribution McLean's design work spans the disparate worlds of national art collections such as the Victoria and Albert Museum (A Hat Anthology Exhibition, and catalogue 2009), London Design Museum ( Fifty Hats that Changed the World 2009). Integrating design considerations of multiple and mass production with the stylistic considerations of the studio workshop McLean brings the wit of the avant garde urban artisan to the structures and systems of fashion industry. The designs reach to a global audience as product users, as well as to the international connoisseurship of crafts and design specialists. The rigour of McLean's research and innovation is evident in the specificity of the stylistic references made through her selection of materials, processes, form, colour and symbolism. A range of cultural references cite the rich fusion of early twentieth century modernist culture in which the disparate worlds of popular, proletarian, culture fertilised the stylistic austerity of high modern formalism. McLean here considers the relationship between millinery and coiffure, following from the millinery piece featured in (Marcel bobbed hairpiece hat), and now brings the considerations of ethnic difference to bear on her design. Afro hair brings user group specificity to the milliner, and the visor design is a resolution of function and style for both protection and display. Connoting the sartorial conventions of workwear headgear, rather than the nineteenth century colonial 'cricketer's' cap, or the twentieth century US 'baseball' peaked cap, McLean's 'Jamaican Olympic Visor' brings distinctively postcolonial meaning to the cultural profile of the heterotopic media space. Designing for the popular culture of Olympic sports, televised and broadcast to global audiences, brings new forms of agency to the fashion designer, and McLan's design deploys a style that is widely recognisable from other popular culture's film and TV depictions of workwear to mark the distinctive tradition of supremacy that black athletes bring to the European traditions of cultural heritage. Supplanting the Arcadian 'laurels' with which winners are, traditionally, crowned, McLean's visor design innovation, suggests that it is not impossible to challenge and transform apparently timeless hierarchies of power and supremacy, so that ex-slaves may also become victors. McLean's fashion designs all work within this reach of fashion towards the carnivalesque inversion of social orderliness through play, display and sartorial activism.

‘Scratch’ investigates the use of physical space as a representation of narrative and dramatic structure. An audio-drama, it is a world-first in being location-sensitive without being tied to any particular place (preceding attempts by others have emphasised location-specific aspects of the genre). Developed in collaboration with and part-funded by BBC Radio Drama, it builds on research undertaken for ‘Dragons’ (output 4). It uses pre-recorded audio on GPS-enabled mobile devices allowing sounds to be virtually attached to locations in an outdoor space. As participants move, they encounter scenes forming a coherent drama which behave differently if the same place is visited more than once. This translocational approach opens novel artistic possibilities exploited through team expertise in narrative, sound design and advanced interaction. It is also significant in the economics of broadcast media as a more viable proposition than the many experimental locative experiences which have been site-specific: this was of great interest to the BBC. The public performance selected for BBC FreeThinking, 1-2 September 2008 in Liverpool as part of European Capital of Culture was reported in a co-authored 2009 conference presentation at ISEA, Belfast, 26-29 August 2009 and in a co-authored short chapter in Spierling and Szilas (eds.) Interactive Storytelling, Springer 2008. Boyd Davis directed the project and devised and undertook the evaluation with 40 trial listeners, reporting to BBC executives (http://researchonline.rca.ac.uk/1000/) for whom a second trial was also run in London in 2009. The evaluation used interview, video observation and a questionnaire combining an open question at the beginning with more specific questions later, avoiding channelling respondents' reactions immediately after the experience into issues which might not be uppermost in their minds, while also yielding data capable of rigorous analysis. The evaluation was to provide feedback to the makers of the drama and to guide policy at the BBC. [287] Participants were recruited principally through the publicity for FreeThinking 2008 – mainly via the festival website. The average age of participants was 40. The gender of participants was 20 males, 17 females and 3 null returns. The evaluation strategy was to combine an open question at the beginning with more specific questions later. In this way we avoided channeling respondents' initial opinions immediately after the experience into issues which might not be uppermost in their minds, while also yielding data capable of rigorous analysis. The purpose of the evaluation was to provide guidance for ourselves as the makers of the drama and to guide policy at the BBC on locative and other interactive media. The responses are analysed in the report.

Cette thèse présente l’analyse des propos de trois générations de femmes réfugiées au Québec sur les manières dont ces femmes s’exposent, s’identifient et s’approprient le discours des médias pour ensuite en discuter entre elles. L’analyse permet de cerner certaines de leurs pratiques d’insertion et d’adaptation à un nouveau milieu de vie. L’immigration favorise de plus en plus l’éclosion des « cultures de la mixité », lesquelles représentent un enjeu incontournable en matière d’intégration. Quant aux médias, ils sont une source incontournable d’accès à l’information et à la culture. Le développement des techniques de transmission telles les réseaux câblés, le satellite de diffusion directe, Internet et le numérique permet au consommateur de médias, quel que soit son origine, de s’approprier de façon personnelle les produits culturels qui en retour déterminent la participation à la vie active dans la société hôte. Cette nouvelle intégration culturelle se transmet-elle aisément au sein des générations d’immigrantes? Cette thèse découle aussi d’un projet plus vaste sur les transmissions intergénérationnelles des savoirs, des pratiques et de l’entraide entre trois générations de femmes réfugiées au Québec (Vatz Laroussi, Guilbert & al. CRSH, 2009-2012). Étudier les transmissions de savoirs au sein des familles immigrantes, c’est reconnaitre avec les auteurs contemporains l’importance de la transmission et de la circulation des histoires personnelles s’inscrivant dans une histoire familiale et sociale de l’époque a méthodologie adoptée s’appuie sur les entretiens semi-directifs, le commentaire réflexif ainsi que l’analyse de contenu. La démarche méthodologique a été empruntée au projet principal. Les entretiens réalisés auprès des familles de réfugiés établis dans plusieurs régions du Québec (Sherbrooke, Joliette, Québec et Montréal) ont été réalisés par une équipe pluridisciplinaire, multiculturelle et féminine. L’originalité de cette recherche se trouve entre autres dans la collecte d’information qui s’est faite auprès de trios générationnels (grand-mère, mère et fille). Chaque membre du trio a été rencontré de façon individuelle et par la suite, le trio s’est formé pour une dernière entrevue de groupe. Ainsi, une analyse thématique des discours des répondants a été réalisée. Cette analyse a permis de mettre en perspective divers éléments proéminents relatifs à la relation entre les médias et chaque membre du trio générationnel. Il a été constaté que les médias sont appréhendés différemment par chaque membre du trio, que des médias comme la télévision et l’Internet sont les plus prisés par les jeunes et ils servent à la fois de fenêtre sur le pays d’accueil, d’ouverture sur le monde et d’expression de soi-même face aux frustrations vécues au Québec. En dernier lieu, une analyse de la question de la transmission intergénérationnelle au prisme des médias entre les trois générations de femme réfugiée a été faite. On constate que dans les trios, la transmission n’est pas unidirectionnelle. Elle va dans tous les sens. Sortant des sentiers battus elle devient un espace de création.

While news stories are an important traditional medium to broadcast and consume news, microblogging has recently emerged as a place where people can dis- cuss, disseminate, collect or report information about news. However, the massive information in the microblogosphere makes it hard for readers to keep up with these real-time updates. This is especially a problem when it comes to breaking news, where people are more eager to know “what is happening”. Therefore, this dis- sertation is intended as an exploratory effort to investigate computational methods to augment human effort when monitoring the development of breaking news on a given topic from a microblog stream by extractively summarizing the updates in a timely manner. More specifically, given an interest in a topic, either entered as a query or presented as an initial news report, a microblog temporal summarization system is proposed to filter microblog posts from a stream with three primary concerns: topical relevance, novelty, and salience. Considering the relatively high arrival rate of microblog streams, a cascade framework consisting of three stages is proposed to progressively reduce quantity of posts. For each step in the cascade, this dissertation studies methods that improve over current baselines. In the relevance filtering stage, query and document expansion techniques are applied to mitigate sparsity and vocabulary mismatch issues. The use of word embedding as a basis for filtering is also explored, using unsupervised and supervised modeling to characterize lexical and semantic similarity. In the novelty filtering stage, several statistical ways of characterizing novelty are investigated and ensemble learning techniques are used to integrate results from these diverse techniques. These results are compared with a baseline clustering approach using both standard and delay-discounted measures. In the salience filtering stage, because of the real-time prediction requirement a method of learning verb phrase usage from past relevant news reports is used in conjunction with some standard measures for characterizing writing quality. Following a Cranfield-like evaluation paradigm, this dissertation includes a se- ries of experiments to evaluate the proposed methods for each step, and for the end- to-end system. New microblog novelty and salience judgments are created, building on existing relevance judgments from the TREC Microblog track. The results point to future research directions at the intersection of social media, computational jour- nalism, information retrieval, automatic summarization, and machine learning.

An algorithm based on a Bayesian network classifier was adapted to produce 10-day burned area (BA) maps from the Long Term Data Record Version 3 (LTDR) at a spatial resolution of 0.05° (~5 km) for the North American boreal region from 2001 to 2011. The modified algorithm used the Brightness Temperature channel from the Moderate Resolution Imaging Spectroradiometer (MODIS) band 31 T31 (11.03 μm) instead of the Advanced Very High Resolution Radiometer (AVHRR) band T3 (3.75 μm). The accuracy of the BA-LTDR, the Collection 5.1 MODIS Burned Area (MCD45A1), the MODIS Collection 5.1 Direct Broadcast Monthly Burned Area (MCD64A1) and the Burned Area GEOLAND-2 (BA GEOLAND-2) products was assessed using reference data from the Alaska Fire Service (AFS) and the Canadian Forest Service National Fire Database (CFSNFD). The linear regression analysis of the burned area percentages of the MCD64A1 product using 40 km × 40 km grids versus the reference data for the years from 2001 to 2011 showed an agreement of R2 = 0.84 and a slope = 0.76, while the BA-LTDR showed an agreement of R2 = 0.75 and a slope = 0.69. These results represent an improvement over the MCD45A1 product, which showed an agreement of R2 = 0.67 and a slope = 0.42. The MCD64A1, BA-LTDR and MCD45A1 products underestimated the total burned area in the study region, whereas the BA GEOLAND-2 product overestimated it by approximately five-fold, with an agreement of R2 = 0.05. Despite MCD64A1 showing the best overall results, the BA-LTDR product proved to be an alternative for mapping burned areas in the North American boreal forest region compared with the other global BA products, even those with higher spatial/spectral resolution

This quantitative study examines the impact of teacher practices on student achievement in classrooms where the English is Fun Interactive Radio Instruction (IRI) programs were being used. A contemporary IRI design using a dual-audience approach, the English is Fun IRI programs delivered daily English language instruction to students in grades 1 and 2 in Delhi and Rajasthan through 120 30-minute programs via broadcast radio (the first audience) while modeling pedagogical techniques and behaviors for their teachers (the second audience). Few studies have examined how the dual-audience approach influences student learning. Using existing data from 32 teachers and 696 students, this study utilizes a multivariate multilevel model to examine the role of the primary expectations for teachers (e.g., setting up the IRI classroom, following instructions from the radio characters and ensuring students are participating) and the role of secondary expectations for teachers (e.g., modeling pedagogies and facilitating learning beyond the instructions) in promoting students’ learning in English listening skills, knowledge of vocabulary and use of sentences. The study finds that teacher practice on both sets of expectations mattered, but that practice in the secondary expectations mattered more. As expected, students made the smallest gains in the most difficult linguistic task (sentence use). The extent to which teachers satisfied the primary and secondary expectations was associated with gains in all three skills – confirming the relationship between students’ English proficiency and teacher practice in a dual-audience program. When it came to gains in students’ scores in sentence use, a teacher whose focus was greater on primary expectations had a negative effect on student performance in both states. In all, teacher practice clearly mattered but not in the same way for all three skills. An optimal scenario for teacher practice is presented in which gains in all three skills are maximized. These findings have important implications for the way the classroom teacher is cast in IRI programs that utilize a dual-audience approach and in the way IRI programs are contracted insofar as the role of the teacher in instruction is minimized and access is limited to instructional support from the IRI lessons alone.

Over the last decade, success of social networks has significantly reshaped how people consume information. Recommendation of contents based on user profiles is well-received. However, as users become dominantly mobile, little is done to consider the impacts of the wireless environment, especially the capacity constraints and changing channel. In this dissertation, we investigate a centralized wireless content delivery system, aiming to optimize overall user experience given the capacity constraints of the wireless networks, by deciding what contents to deliver, when and how. We propose a scheduling framework that incorporates content-based reward and deliverability. Our approach utilizes the broadcast nature of wireless communication and social nature of content, by multicasting and precaching. Results indicate this novel joint optimization approach outperforms existing layered systems that separate recommendation and delivery, especially when the wireless network is operating at maximum capacity. Utilizing limited number of transmission modes, we significantly reduce the complexity of the optimization. We also introduce the design of a hybrid system to handle transmissions for both system recommended contents ('push') and active user requests ('pull'). Further, we extend the joint optimization framework to the wireless infrastructure with multiple base stations. The problem becomes much harder in that there are many more system configurations, including but not limited to power allocation and how resources are shared among the base stations ('out-of-band' in which base stations transmit with dedicated spectrum resources, thus no interference; and 'in-band' in which they share the spectrum and need to mitigate interference). We propose a scalable two-phase scheduling framework: 1) each base station obtains delivery decisions and resource allocation individually; 2) the system consolidates the decisions and allocations, reducing redundant transmissions. Additionally, if the social network applications could provide the predictions of how the social contents disseminate, the wireless networks could schedule the transmissions accordingly and significantly improve the dissemination performance by reducing the delivery delay. We propose a novel method utilizing: 1) hybrid systems to handle active disseminating requests; and 2) predictions of dissemination dynamics from the social network applications. This method could mitigate the performance degradation for content dissemination due to wireless delivery delay. Results indicate that our proposed system design is both efficient and easy to implement.

The next generation of vehicles will be equipped with automated Accident Warning Systems (AWSs) capable of warning neighbouring vehicles about hazards that might lead to accidents. The key enabling technology for these systems is the Vehicular Ad-hoc Networks (VANET) but the dynamics of such networks make the crucial timely delivery of warning messages challenging. While most previously attempted implementations have used broadcast-based data dissemination schemes, these do not cope well as data traffic load or network density increases. This problem of sending warning messages in a timely manner is addressed by employing a network coding technique in this thesis. The proposed NETwork COded DissEmination (NETCODE) is a VANET-based AWS responsible for generating and sending warnings to the vehicles on the road. NETCODE offers an XOR-based data dissemination scheme that sends multiple warning in a single transmission and therefore, reduces the total number of transmissions required to send the same number of warnings that broadcast schemes send. Hence, it reduces contention and collisions in the network improving the delivery time of the warnings. The first part of this research (Chapters 3 and 4) asserts that in order to build a warning system, it is needful to ascertain the system requirements, information to be exchanged, and protocols best suited for communication between vehicles. Therefore, a study of these factors along with a review of existing proposals identifying their strength and weakness is carried out. Then an analysis of existing broadcast-based warning is conducted which concludes that although this is the most straightforward scheme, loading can result an effective collapse, resulting in unacceptably long transmission delays. The second part of this research (Chapter 5) proposes the NETCODE design, including the main contribution of this thesis, a pair of encoding and decoding algorithms that makes the use of an XOR-based technique to reduce transmission overheads and thus allows warnings to get delivered in time. The final part of this research (Chapters 6--8) evaluates the performance of the proposed scheme as to how it reduces the number of transmissions in the network in response to growing data traffic load and network density and investigates its capacity to detect potential accidents. The evaluations use a custom-built simulator to model real-world scenarios such as city areas, junctions, roundabouts, motorways and so on. The study shows that the reduction in the number of transmissions helps reduce competition in the network significantly and this allows vehicles to deliver warning messages more rapidly to their neighbours. It also examines the relative performance of NETCODE when handling both sudden event-driven and longer-term periodic messages in diverse scenarios under stress caused by increasing numbers of vehicles and transmissions per vehicle. This work confirms the thesis' primary contention that XOR-based network coding provides a potential solution on which a more efficient AWS data dissemination scheme can be built.
