Tra, Bi Zamblé Mathieu. „Polyphonie sur les médias socionumériques : le cas des interactions sur YouTube à propos des feux de forêt d’Amazonie“. Electronic Thesis or Diss., Bourgogne Franche-Comté, 2024. http://www.theses.fr/2024UBFCC002.
Der volle Inhalt der QuelleThis study examines polyphonic enunciation in online writings, focusing on that which arises from and is induced by interactions on YouTube during the Amazon rainforest wildfires. After presenting the context and the concepts and theories related to polyphony, it proposes a methodological framework for analyzing polyphony that first captures the role of techno-semiotic, socio-economic, and psychosociological aspects of YouTube in polyphony, and then interrogates this polyphony at the level of other media actors mentioned from YouTube. This allows us to identify consistencies and changes in polyphonic configurations during our observation period and to show how these polyphonic configurations during the Amazon rainforest wildfires could be influenced by exogenous contextual variables. We also observe power dynamics when this polyphony is used as a strategy by various media actors involved in the social controversy surrounding the Amazon rainforest wildfires. This study complements previous research on editorial enunciation in screen writings by considering polyphony at both the network actors’ level and the argumentation level
Portilla, Yonathan. „Etude des Réseaux Sociaux : modélisation et analyse“. Thesis, Avignon, 2019. http://www.theses.fr/2019AVIG0235.
Der volle Inhalt der QuelleCurrently social networks focus on the sharing and exchange of opinions, videos, photos, music,news and others informations, one of its objectives is to establish direct and indirect linkswith users. Social networks also promote products, people (their political or artistic image) orinfluential brands.Social networks are changing rapidly, so we’re looking to see the evolution of these sharingtools, and see how social networks change over time.We have the opportunity to study the events that occur in social networks thanks to the amount ofdata they produce. In the current market there are tools that allow the analysis of social networks,but most tools are not free, and 100% free tools disappear over time. For this reason we decidedto produce computer tools able to extract and analyse the data of the social networks studied.This study begins with the state of the art, where we describe the context of the problem, thework that led to this study and a summary of the contributions made during the thesis that wepresent briefly in the rest of the abstract.i. First we focus on the geo-linguistic fingerprint and language evolution in Twitter. Accessto content of messages sent by a group of subscribers of a social network may be usedto identify and quantify some features of a group. The feature can represent the level ofinterest in an event or product, or the popularity of an idea, or of a musical hit, or of apolitical figure. The feature can also represent how language is used and transformed,how words are written and how new grammatical rules appear.ii. Then we study the evolution of the cultural phenomenon called meme in social networks.Memes were defined by R. Dowkins as a cultural phenomenon that spreads through nongeneticforms. We examine three of the most popular memes of the internet and examinetheir impact on society in the Mediterranean countries. We use for analysing Google Trends, Topsy (a tool to measure the popularity of words on Twitter) and YouTube toquantify the impact of memes in the Mediterranean society.iii. After that we study the YouTube recommendation graph based on measurements andstochastic tools. We confirm that recommendation lists influence the views of a video.We focus on the recommendation system that boosts the popularity of videos. We buildfirst a graph that captures the recommendation system in YouTube and we study the relationshipbetween the number of views of a video and the average number of views of avideo in its recommendation list.iv. To conclude we describe the online tools available and the tools that we developed duringthe thesis. The online tools Topsy, Trendistic and Google Trends allowed us to analyseplatforms like YouTube and Twitter. We also produced tools based on API’s: in Twitterwe used the Streaming function to download and analyse tweets, with the Topsy APIwe studied the evolution of the language and the use of words, and the YouTube’s APIsallowed us to describe the behaviour on the lists of recommendations and the popularityof videos
Hoff, Rafael Sbeghen. „Um olhar pela Porta dos Fundos : apontamentos sobre o humor político audiovisual no Youtube“. reponame:Biblioteca Digital de Teses e Dissertações da UFRGS, 2018. http://hdl.handle.net/10183/180560.
Der volle Inhalt der QuelleThe thesis investigates how the political humor of “Porta dos Fundos” in audiovisual sketches transmitted by Youtube is presented. It started by a panorama on the audiovisuals to look at productive processes in relation to national socioeconomic and political contexts. Henry Bergson (1983) and Elias Thomé Saliba (2002) trigger ehe concepts of comics and humor. The first one being taken as the system organizer of the narrative from the intentionality of making laugh, while the second one is defined by the contrast between what is and what should be, triggering a critical reflection that complements and gives the tone of the social gesture employed by comedians. To deal with audiovisual humor, we go through the story of laughter and scorn with Georges Minois (2003), Roberto Elísio dos Santos and Regina Rosseti (2012), among others, in order to rescue the roots of Brazilian disseminated laught. The research problem is: How does the political humor in the audiovisual comedy of “Porta dos Fundos”work? In order to answer this question we have as a general objective of the research to describe and analyze how audiovisual political humor is presented in a channel on YouTube – called Porta dos Fundos, exploring the object in relation to the field of the national audiovisual, with the contemporary political context and with the theory about humor and comedy. From this, specific objectives are stablished: a) to describe the possible relations between the matrix of the national audiovisual comedy and the political humor conveyed by Porta dos Fundos; b) describe and analyze how the audiovisual contents present the political humor of Porta dos Fundos; c) to point out clues that indicate elements of distinction of the humoristic content of Porta dos Fundos in the field of contemporary audiovisual We understand that in order to approach the political humor of Porta dos Fundos on Youtube it is necessary to contextualize the contemporary digital and digital culture, relating it to the actual political and economic context in Brazil during the period of analysis, searching for relational look that points out clues about how agents and social fields influence each other and which brands leave in one another. The epistemology adopted is Pierre Bourdieu's (1997, 2002, 2007a, 2007b), relational sociology, which assists in the treatment given to the empirical corpus of six audiovisual humoristic sketches transmitted by Youtube, in between august of 2012 and april of 2017, and analyzed in the movie by the methodological propositions of Penafria (2009), Julier and Marie (2009). As a result we find distinctive marks of the political humor of Porta dos Fundos from their narrative strategies that privilege the sense of reality with the spectator; a collaborative production process that diversifies the content and strengthens the brand image; a visual identity (aesthetic and linguistic) maintained even with the rotation of functions and collaborators; all marking a phenomenon that emerges in a time that lacs critical political humor on TV, public policies that encourage independent audiovisual production and converge with the expansion of connectivity and digital culture in the country.
Conter, Marcelo Bergamin. „Imagem-Música em vídeos para web“. reponame:Biblioteca Digital de Teses e Dissertações da UFRGS, 2012. http://hdl.handle.net/10183/49264.
Der volle Inhalt der QuelleThe present dissertation proposes to investigate how music over-codifies the audiovisual language of web videos, creating new signification processes and complexifying the musical virtuality (here understood as the unrepresentable totality of images that express it). YouTube’s website is established as a privileged locus for such study because it contains a significant amount of music videos in which music manifests itself in every audiovisual element, interfering in the audiovisual composing process (both in the visual and the sound tracks), which is edited according to musical rules. What may come from this encounter are updates and potentialities from the music’s virtual, manifested in the form of what will be here understood as image-music. The videos that compose the work's corpus are organized in four categories that are defined according to videoclip's language proximity: audiovisual mash up, audiovisual sampling, shreds spoofs, and auto-tuning. This procedure allows us to perceive how, progressively, in web videos, an empowerment of music-image is occurring. These practices were already contained, potentially, in previous audiovisuals, like cinema, television, video art and video clips – and also on electronic music practices –, but only in the web they managed to be fully manifested. Different theories will be presented and utilized as theoretical references, like those of French philosopher Henri Bergson, which will be used to comprehend music’s virtuality; works from Gilles Deleuze, will be utilized to aid our understanding of the signification processes that music’s over-codification performs on audiovisual, and how its structure is altered by it through this process; from Nicklas Luhmann's theories will provide a different point of view, on web music videos; and Vilém Flusser’s works will be employed to understand the nature of the technical image. We conclude that the web videos analyzed effectively move away from the logic of television music video, first, because they do not dialogue with the recording industry’s logic; second, because the songs created result from editing and not the other way around, as often occurs in video clips; third, it becomes clear that music is able to print something out of itself on the studied videos, there is an ongoing tendency for the dilution of the distinction between figurative art and music; throughout these videos, the production of imaginative music becomes possible, created from the recycling of audiovisual material available on the web.

Der volle Inhalt der QuelleOur work aims at studying websites as the substantial objects of the Web universe. Our approach yields from an analysis of websites contents, from the point of view of their material form and of the complex mediations that emerge among users, the medium and content publishers. The thesis is articulated along the following axes : questioning the nature of the « website object » in its relation to the communication partners ; observation and analysis of the transformations induced by the Web to the conditions of sense production ; observation of the way the transformations of institutional positions and of mediations with respect to the Web productions are expressed. In particular, we investigate the metaphor-based mechanisms that arise involving website designers' strategies, users' practices and medium proprieties

Der volle Inhalt der QuelleThis research aims to understand how the visual electronic word of mouth emitted by a youtubeur influences the affect and the purchase intention of the consumers. We study the impact of word of mouth characteristics and the effect of social contagion.The main results are:1. The professional status of the youtubeur, the existence of commercial links between brands and youtubers and the valence of the magazine have an impact on the feeling expressed and therefore the intention to purchase.2. There is a social contagion, both emotional and behavioral within the audience of electronic and visual word of mouth that impacts its effectiveness.3. The number of subscribers of an individual (individual characteristic of the commentator) impacts his sensitivity to social contagion
El, mouldi Sana. „Communautés virtuelles sur youtube : quand les marques s'associent aux youtubeurs“. Thesis, Bordeaux, 2020. http://www.theses.fr/2020BORD0040.
Der volle Inhalt der QuelleInfluence marketing is increasingly being used by companies in their digital strategies. This interest is explained by the effectiveness of influencers and their recommendations on consumer behaviour. This research focuses on Youtube subscribers' attitudes towards Youtubeur and brand partnerships. Two exploratory studies were conducted. Face-to-face interviews helped to better understand how Youtube works, to highlight the motivations of Internet users to subscribe to a channel and to identify the importance of the personality and attractiveness of the Youtubeur. A netnography was performed by analyzing three fashion and beauty channel videos that together total 2075 comments. The analyses revealed three types of attitudes : cognitive, affective and conative, towards the partnership, the Youtubeuse and the brand. Finally, a quantitative study was conducted to test the influence of the youtubeur’s credibility on subscribers' attitudes towards the brand, the video and their purchasing intention
Rondot, Camille. „Représenter et incarner une organisation internationale : analyse d’une prétention communicationnelle sur le site internet de l’UNESCO“. Thesis, Paris 4, 2015. http://www.theses.fr/2015PA040094.
Der volle Inhalt der QuelleIf the UNESCO’s website is now considered by the organization as the most suitable media for its communication, this thesis focuses on the denaturalization of this apparent evidence. It brings to light a communicational claim based both on the nature of the organization, invested devices and the particular competency of the UNESCO: the mediation of knowledge. This thesis also focuses on the symbolic issues of the media representation of the UNESCO’s promoted by its website. This thesis relies on a techno-semiotic-discursive methodology, based on the analysis of the signs, mobilizing the discourses produced by the organization on its website and considering the technical specifications of the invested devices. This thesis shows how the website embodies a particular concept of the mediation of knowledge resulting from the encounter between a media and an organization. It also leads us to consider the close relationship between knowledge and policy in the definition of the posture of the organization, represented and embodied by its website
Heuguet, Guillaume. „Métamorphoses de la musique et capitalisme médiatique. Au prisme de YouTube (2005-2018)“. Thesis, Sorbonne université, 2018. http://www.theses.fr/2018SORUL153.
Der volle Inhalt der QuelleWhile music digitization has become a major theme of public discourse and academic research, YouTube, a video publication website founded by three ex-employees of PayPal and now the property of Google, is today recognized as the first media used for music listening in France. Through an analysis of digital archives of the Web and the compilation of media sources, this thesis analyzes what a company coming from technology « does » to musical culture, taking into account the regular change of its forms and its promises. A first chapter deals with the effects of power and blurriness in the mediatization of YouTube and its relationship to music. A second chapter analyzes the way music shaped YouTube, proposing a genealogy of relationships between music and media apparatus, linking the invention of recorded music, the standardization of online listening software and the « musicalization » of YouTube. A third chapter discusses music as an opportunity. We identify how the company invested in music as a key strategic ressource, while shaping the practice of music gathering and publication around values of popularity and creativity. A fourth chapter concerns the construction of a market for music built upon the technological and juridical control of the works versions and the financing by advertising, interrogating the limits of this model. We conclude by showing the intricacy of discourse about the transformation of musical culture with the logics of permanent change from the actors of media capitalism. From this point, we defend the necessity of studying the micropolitics of formats
Khokhar, Muhammad Jawad. „Modélisation de la qualité d'expérience de la vidéo streaming dans l'internet par expérimentation contrôlée et apprentissage machine“. Thesis, Université Côte d'Azur (ComUE), 2019. http://www.theses.fr/2019AZUR4067.
Der volle Inhalt der QuelleVideo streaming is the dominant contributor of today's Internet traffic. Consequently, estimating Quality of Experience (QoE) for video streaming is of paramount importance for network operators. The QoE of video streaming is directly dependent on the network conditions (e.g., bandwidth, delay, packet loss rate) referred to as the network Quality of Service (QoS). This inherent relationship between the QoS and the QoE motivates the use of supervised Machine Learning (ML) to build models that map the network QoS to the video QoE. In most ML works on QoE modeling, the training data is usually gathered in the wild by crowdsourcing or generated inside the service provider networks. However, such data is not easily accessible to the general research community. Consequently, the training data if not available beforehand, needs to be built up by controlled experimentation. Here, the target application is run under emulated network environments to build models that predict video QoE from network QoS. The network QoS can be actively measured outside the data plane of the application (outband), or measured passively from the video traffic (inband). These two distinct types of QoS correspond to the use cases of QoE forecasting (from end user devices) and QoE monitoring (from within the networks). In this thesis, we consider the challenges associated with network QoS-QoE modeling, which are 1) the large training cost of QoE modeling by controlled experimentation, and 2) the accurate prediction of QoE considering the large diversity of video contents and the encryption deployed by today's content providers. Firstly, QoE modeling by controlled experimentation is challenging due to the high training cost involved as each experiment usually consumes some non-negligible time to complete and the experimental space to cover is large (power the number of QoS features). The conventional approach is to experiment with QoS samples uniformly sampled in the entire experimental space. However, uniform sampling can result in significant similarity in the output labels, which increases the training cost while not providing much gain in the model accuracy. To tackle this problem, we advocate the use of active learning to reduce the number of experiments while not impacting accuracy. We consider the case of YouTube QoE modeling and show that active sampling provides a significant gain over uniform sampling in terms of achieving higher modeling accuracy with fewer experiments. We further evaluate our approach with synthetic datasets and show that the gain is dependent on the complexity of the experimental space. Overall, we present a sampling approach that is general and can be used in any QoSQoE modeling scenario provided that the input QoS features are fully controllable. Secondly, accurate prediction of QoE of video streaming can be challenging as videos offered by today's content providers vary significantly from fast motion sports videos to static lectures. On top of that, today's video traffic is encrypted, which means that network operators have little visibility into the video traffic making QoE monitoring difficult. Considering these challenges, we devise models that aim at accurate forecasting and monitoring of video QoE. For the scenario of QoE forecasting, we build a QoE indicator called YouScore that quantifies the percentage of videos in the catalog of a content provider that may play out smoothly (without interruptions) for a given outband network QoS. For the QoE monitoring scenario, we estimate the QoE using the inband QoS features obtained from the encrypted video traffic. Overall, for both scenarios (forecasting and monitoring), we highlight the importance of using features that characterize the video content to improve the accuracy of QoE modeling

Étude sémiotique des vidéos promotionnelles et du site web participatif Sharek : Al Jazeera face à la guerre de Gaza (2009) et aux révolutions arabes (2011)“. Thesis, Paris 2, 2018. http://www.theses.fr/2018PA020028/document.
Der volle Inhalt der QuelleThe co-production of information with the Arab viewer has always been the directive editorial line that distinguished the Qatari channel Al Jazeera since its creation in 1996. Over the years, the recipe has paid off, making Al Jazeera the most watched international news channel in the Arab world. The strategic choice of the channel to make the Arab spectator, long marginalized in the media, an ally is explained by a desire for legitimacy by the emir Hamad ben Khalifa al-Thani especially after the coup against his father in 1995. Nevertheless, cutting off from the old regime imposes substantial changes. With the first political debates on Al Jazeera, the status of the Arab viewer changes dramatically. They become actors and participate with their questions and comments at the cost of a simple phone call. But at the same time, Al Jazeera becomes the enemy of the Arab regimes. Over the years, the Qatari channel won the trust of many viewers, especially during its coverage of major crises in the Arab world, like the second Intifada in 2000 and the American invasion of Iraq in 2003. Through its media coverage from the ground in hot zones, it differentiates itself from other news channels. The year of 2011 was a major turning point in the history of the channel. From day one, Al Jazeera covered the rising demonstrations in the Arab countries. The declared war of autocratic regimes against Al Jazeera does not prevent it from covering stories. Aware of the contributions of digital media, the channel gives spectators the means to participate in the creation and circulation of information. The promotional videos of Al Jazeera are a concrete example. Throuh their short form which enables them to travel from one medium to another; they become an object of media activism. As for the digital platform Sharek, it shows how the channel involves the Arab spectator in the process of spreading and archiving information

Der volle Inhalt der QuelleThe purpose of this thesis is to identify criteria to understand how contemporary artworks make sense in public space. When conflict of opinions happen, protagonists are led to rise in generality to justify their point of view, which allows the researcher to access at values giving a meaning to the object. However, the influence of the promotional discourse from the contemporary art world and the constraints that transformed art criticism in a journalism disengaged and consensual make problematic the legitimacy of a negative critique in the public space. First, the research focused on the subjects covered by newscast about contemporary art in order to understand criteria raised by this communication journalism that tries to satisfy the variety of accepted values by society. Then, disputes on the social network YouTube were analyzed. These give access to a speech freed from the constraints of the art world and journalism where the expression of a negative critique is possible. Thanks to sociology of values and a discourse analysis, it was possible to typify the receivable arguments in the public sphere. This patterning allows to state the hypothesis that the political meaning given to art defuses, paradoxically, the possibility of controversy. This politicization of art promotes evaluation criteria of artworks whose consistency appears considering the ‘‘insolite’’ as a new aesthetic category common to different cultural practices

Der volle Inhalt der QuelleAdvertising is ubiquitous in nearly all current media : the press, television, radio stations. For several decades, its use has considerably expanded and evolved. Recently, however, it has acquired a new dimension thanks to new, cutting-edge information technologies. Indeed, the spread of the Internet and its expanding resources have ushered in new forms of advertising communication – which occupy a large part of the global Web's virtual space.Many studies have been performed concerning advertising in traditional media. However, messages posted via online dating sites have seldom been seriously investigated. And yet, they can be considered as advertising discourses. Hence, they constitute a relatively new research field.This thesis endeavours to study their semiotics, focusing notably on their various forms, techniques, strategies, and objectives.We chose to analyse the advertising discourses published on two French dating sites steeped in two different cultures, and on an Arab site – to compare their respective ways of adjusting to the language and cultural environment of their different targeted audiences.We focused our research on the following Internet dating sites : Meetic, in its French-language version Inch’Allah, a French-language site aimed at Muslims around the world. Iraqroom, an Iraqi site targeting Arab-speaking persons wishing to marry

Der volle Inhalt der QuelleThis research aims to deepen present-day scientific knowledge about politicians’ communication on Twitter in different national contexts. Namely, it proposes a new angle of analysis through the notion of semiosphere. The PhD examines components of political discourse on Twitter, by means of Lotman’s theory of the semiosphere, particularly their structure as a coherent semiotic space created around an “event” on a digital platform. This analysis deals with the questions of modelling, representing and interpreting of an “event” within the discourses put in different cultural contexts. The PhD is based on the quantitative but especially qualitative analysis of different language-based corpora (French, British, German, Russian). The research mobilises a variety of theoretical approaches, in order to set up a contrastive as well as comprehensive approach to the analysis of political communication on Twitter

Der volle Inhalt der QuelleStudent activism, like all types of activism, has undergone a number of fundamental changes over recent decades. These changes have often been reduced to an opposition between membership activism and what Jacques Ion calls post-it activism. Through a series of interviews held with students active within not for profit organisations, political organisations, unions as well as students categorised as alter-activists, this PhD thesis presents an inventory of how different forms of activism work as experimental spaces and influence the identity and political construction of individuals. Moreover, this PhD thesis revises the binary opposition between the militant form of membership activism and the detached form of post-it activism, and contends that the notion of intensity is no longer relevant as it cannot be measured against how long someone is a affiliated to an organisation because today new forms of activism relate to several different spheres in the life of an individual.By articulating the sociology of agency, social movement theory, the sociology of youth and the sociology of the public sphere, this PhD thesis brings to light new shifts in student activism within the context of individualisation and advanced modernity
Frini, Marouane. „Diagnostic des engrenages à base des indicateurs géométriques des signaux électriques triphasés“. Thesis, Lyon, 2018. http://www.theses.fr/2018LYSES052.
Der volle Inhalt der QuelleAlthough they are widely used, classical vibration measurements have several limitations. Vibration analysis can only identify about 60% of the defects that may occur in mechanical systems. However, the main drawbacks of vibration measurements are the difficult access to the transmission system in order to place the sensor as well as the consequent cost of implementation. This results in sensitivity problems relative to the position of the installation and the difficulty to distinguish the source of vibration because of the diversity of mechanical excitations that exist in the industrial environment.Hence, the Motor Current Signatures Analysis (M.C.S.A.) represents a promising alternative to the vibration analysis and has therefore been the subject of increasing attention in recent years. Indeed, the analysis of electrical signatures has the advantage of being a technically accessible method as well as inexpensive and non-intrusive to the system. Techniques based on currents and voltages only require the motor’s electrical measurements which are often already supervised for the purposes of the control and the protection of the electrical machines. This process was mainly used for the detection of motors faults such as rotor bars breakage and eccentricity faults as well as bearings defects. On the other hand, very little research has been focused on gear faults detection using the current analysis. In addition, three-phase electrical signals are characterized by specific geometric representations related to their waveforms and they can serve as different indicators providing additional information. Among these geometric indicators, the Park and Concordia transforms model the electrical components in a two-dimensional coordinate system and any deviation from the original representation indicates the apparition of a malfunction. Moreover, the differential equations of Frenet-Serret represent the trajectory of the signal in a three-dimensional euclidean space and thus indicate any changes in the state of the system. Although they have been previously used for bearing defects, these indicators have not been applied in the detection of gear defects using the analysis of electrical current signatures. Hence, the innovative idea of combining these indicators with signal processing techniques, as well as classification techniques for gears diagnosis using the three-phase motor’s electrical current signatures analysis is established.Hence, in this work, a new approach is proposed for gear faults diagnosis using the motor currents analysis, based on a set of geometric indicators (Park and Concordia transforms as well as the properties of the Frenet-Serret frame). These indicators are part of a specifically built fault signatures library and which also includes the classical indicators used for a wide range of faults. Thus, a proposed estimation algorithm combines experimental measurements of electrical signals with advanced signal processing methods (Empirical Mode Decomposition, ...). Next, it selects the most relevant indicators within the library based on feature selection algorithms (Sequential Backward Selection and Principal Component Analysis). Finally, this selection is combined with non-supervised classification (K-means) for the distinction between the healthy state and faulty states. It was finally validated with a an additional experimental configuration in different cases with gear faults, bearing faults and combined faults with various load levels
