El presente artículo tiene como objetivo analizar la cobertura periodística de los diarios Expreso y Diario Uno sobre la manifestación en contra de Keiko Fujimori previo a la segunda vuelta electoral en 2016. Se conoce que ambos periódicos presentan una línea editorial opuesta entre ellos. Se utilizó como método el análisis de contenido de una muestra de 32 notas que salieron entre el día del anuncio de la marcha, la fecha en la que se llevó a cabo y el día posterior a este. Como resultado se encontró que Expreso dedicó menos espacio a informar sobre este hecho y solo lo mencionó por medio de la participación de Pedro Pablo Kuckzynski. En cuanto a Diario Uno, el tono con el que trató este hecho noticioso se caracterizó por ser favorable, además de brindarle espacio a fuentes cercanas al colectivo “No a Keiko”, principal promotor de la manifestación. / The purpose of this article is to analyze the journalistic coverage of the Expreso and Diario Uno newspapers on a demonstration against Keiko Fujimori prior to the second round of elections in 2016. It is known that both newspapers have an opposite editorial line between them. The content analysis of a sample of 32 notes that came out between the day of the anouncement of the protest, the protest, the day it was realized and the day after it. As a result, it was found that Expreso dedicated less space to report on this fact and only mentioned it through the participation of Pedro Pablo Kuckzynski. As for Diario Uno, the tone with which it dealt with this news event was characterized by being favourable, in addition to providing space to closer sources of the collective “No a Keiko”, the main promoter of the demonstration. / Tesis

Cette recherche porte sur l’analyse des problématiques narratologiques et stylistiques dans les écrits parus à la fin du soulèvement populaire survenu en Égypte en 2011. Elle entrecroise deux axes, l’un notionnel et l’autre analytique. D’une part, elle aborde la question du genre littéraire, de l’espace, de la temporalité et de la langue d’écriture. D’autre part, on se propose de comparer cinq textes, qu’on envisagera dans leur double appartenance littéraire et thématique : Ayyām al-Taḥrīr (2011), Cairo : my city, our revolution (2012), al-Ṯawra 2.0 (2012), Aǧniḥat al-farāša (2011) et Sabʿat ayyām fī al-Taḥrīr (2011). Nous examinerons ces œuvres dans le cadre de ce que les critiques ont désigné sous le nom d’adab al-ṯawra ou d’adabiyyāt al-ṯawra – « littérature(s) de la révolution » – et tenterons d’identifier les caractéristiques et les particularités de cette très jeune production. L’enjeu est d’étudier comment les écrivains égyptiens contemporains produisent des narrations à travers lesquelles se déploie un processus d’émerveillement, de reconfiguration et de modification de la représentation du citoyen, notamment celle des jeunes. / This research focuses on narratological and stylistic issues in the writings that appeared at the end of the popular uprising in Egypt in 2011. It combines two axes, one notional and the other analytical. On the one hand, it deals with questions of literary genre, space, temporality and language of writing. On the other hand, it offers to compare five texts which will be examined at the literary as well as at the thematic level : Ayyām al-Taḥrīr (2011), Cairo: my city, our revolution (2012), al-Ṯawra 2.0 (2012), Aǧniḥat al-farāša and Sabʿat ayyām fī al-Taḥrīr (2011). These works are considered within the framework of what critics have called adab al-ṯawra or adabiyyāt al-ṯawra--"literature(s) of the revolution". I try to highlight the characteristics and peculiarities of this very young production. The challenge here is to study how contemporary Egyptian writers have produced narratives which reveal a process of wonderment, reconfiguration and transformation of the representation of the citizen, especially that of young people.

<div>Social influence networks are collections of entities dealing with a shared issue on which they have individual opinions. These opinions are dynamic, changing over time due to influence from other entities. Mechanisms within the network can affect how influence leads to opinion change, such as the strength and number of social ties between agents and the decision models used by an individual to process information from its neighbors. In real-world scenarios, these mechanisms are often hidden. Much effort in social network analysis involves proposing models and attempting to replicate target output data with them. Can we instead use the evolution of opinions in a network to infer these mechanisms directly?</div><div><br></div><div>This work explores how opinion change in social influence networks can be used to determine characteristics of those networks. Broadly, this is accomplished by simulating social influence networks using various designs and initial conditions to generate opinion data, and then identifying relationships between response variables and changes to the simulation inputs. Key inputs include the population size, the influence model that controls how agents change their opinions, the network structure, the activation regime that controls the sequencing of opinion updates, and probability distributions for communication errors. Analyzing the opinions of individual agents can provide insights about the individuals (microscopic), but in this work, focus is on insights into the social influence network as a complete system (macroscopic), so opinion data is aggregated according to each response variable.</div><div><br></div><div>Response variables are designed through the lens of complexity theory. Three types of complexity measurements are applied to opinion data: regression, entropy, and a new complexity measure. In each case, relationships between design factors and response variables are diverse. The influence model and the distribution of communication errors---a factor often omitted from the literature---are consistently impactful, with their various settings producing distinct profiles in time series plots of the measurements. Activation regime is impactful to some entropy measures. Network structure has little impact on the new complexity measure, and population size has little impact in general. Overall, distinctive relationships can exist between opinions and design factors. These relationships, as well as the measures and problem-solving approaches used in this work, may be helpful to analysts working to infer the properties of real-world social influence networks from the opinion data those systems generate.</div>

Social shopping is one of the latest trends on the Internet. Websites dedicated to social networking with a focus on shopping have been emerging on the web for a few years. The basic idea is that consumers are looking for product information on the Internet and social shopping sites provide a place for consumers to find this information from other consumers. These sites provide a place for their users to engage in socialization and shopping simultaneously, sometimes following recommendations of premier users, who are labeled from other users. However, purchases aren't made through these sites. So, there may still be something missing from the experience. For these sites, social pricing mechanisms may be implemented to provide revenue. Major ecommerce websites have begun focusing on increasing social features throughout the transaction process. For example, more websites are including ratings, reviews and recommendations of products and services by other consumers. However, pure ecommerce websites do not provide functionality that allows consumers to communicate in real time. Hence, there are some features missing from the social experience. Also, the social functionality included in pure e-commerce websites, tends to be utilized for the benefit of the Web site, as opposed to the consumers. Both social shopping sites and ecommerce sites have seen independently successful though few sites have been able to truly integrate these together at this point. It may be more beneficial to the end user if these sites could work in unison. This thesis is an exploratory study of the emerging social shopping phenomenon. The contributions of this work include analysis of the social shopping phenomenon and identifying metrics and Web sites that incorporate social shopping, a survey of academic literature related to social shopping and social pricing and a review of current recommender system algorithms with a discussion on how to incorporate social networking data into the algorithms to improve recommendations. Improvement suggestions include incorporating customer purchase history with social networking information. Potential future research ideas are included.

Les médias produits par et/ou pour les minorités ethniques et immigrantes (au sens traditionnel du terme) ont longtemps été l’outil de communication des privilégiés de ces groupes. Avec la démocratisation de l’accès aux nouvelles technologies dont Internet et le Web, et surtout avec l’expansion des médias socio-numériques, ces minorités ont pu devenir consommatrices mais aussi productrices de contenus numériques. Ces dispositifs leur permettent également de garder le contact avec leurs proches et les membres de leur communauté dans le pays d’accueil. Ces médias revêtent donc aujourd’hui une double fonction : garder le lien avec leur communauté et diffuser des informations présentant un intérêt pour elle. Par ailleurs, la dimension sociale de ces outils numériques leur confère une troisième fonction : celle d’établir des liens avec la société de leur pays d’accueil. Grâce à cette sociabilité en ligne, une relation se construit, et elle contribué à l’intégration de ces communautés au sein de leur nouvel environnement social, linguistique et culturel. Pour étudier ce potentiel processus d’intégration, nous avons travaillé depuis 2011 avec les membres adolescents d’une communauté cap-verdienne résidente dans la ville de Nice, afin d’analyser leur réseau social en ligne et hors ligne et leurs pratiques du réseau socio-numérique Facebook. Par l’usage de l’ethnographie des réseaux sociaux et de la netnographie, nous avons étudié leurs pratiques pendant sept ans et essayé de comprendre dans quelle mesure ces dispositifs pourraient contribuer à l’intégration des minorités ethniques et immigrantes en France. / Since long back, traditional media produced by and for immigrant and ethnic minorities, have been the preferred communication tools of these communities. Through the democratization of the access to new technologies such as Internet and ‘the Web’, and in particular through the expansion of social networks, these minorities have become consumers and producers of user generated content. Such tools also allow them to stay in contact with their relatives and the members of their community in the adopted country. Thus, this media has a double function: it facilitates keeping in touch with the user’s community, and it provides a means for sharing information relevant for the latter. Moreover, the social dimension of these digital tools gives them a third functionality: it establishes connections with the society of the foster country. Thanks to this online sociability, a relation is formed and this contributes to the integration of the communities within their new social, linguistic and cultural environment. In order to study this potential integration process, I have since 2011 worked with teenage members of a Cape Verdean community living in Nice, France. The objective has been to analyze their social networking online and offline, and their use of Facebook. From a methodological standpoint, this study has been conducted by the use of social network ethnography and of Netnography. The work is the results of seven years of observations of practices in the online and offline worlds, with the objective to provide an understanding of how social media can contribute to the integration of ethnic and immigrant minorities in France.

Eles favorecem a construção e a produção de discursos que manifestam as múltiplas "verdades" sociais e suas representações. Além disso, são espaços complexos que estimulam o debate, geram ou desoprimem as tensões e, sobretudo, trazem os discursos sociais que refletem os valores e a moral de seus participantes. Nos Sites de Redes Sociais o ideal admitido é a liberdade e, portanto, os usuários tendem a avaliar e julgar a ação dos demais e vão além, aplicam sanções que bem entendem. O objetivo geral da pesquisa foi verificar e analisar como algumas questões relativas à moralidade apareceram nas publicações dos usuários e moldaram as suas ações dentro do Facebook. Temos como justificativa a necessidade de estudos que explorem a moralidade "virtual" dos participantes e apresentem programas e estratégias que promovam o uso consciente e responsável. Para tanto utilizamos como metodologia a netnografia. Ela consiste em uma pesquisa observacional participante, pois permite que o pesquisador adentre no universo que estuda por um determinado tempo, utilizando-se além das ferramentas próprias do Facebook, o diário de campo. Para cumprir com objetivos acessamos a plataforma diariamente durante o período de Junho de 2017 à Agosto de 2018, em busca de casos que causavam grande indignação nos usuários e eram as mais polêmicas da época. Além disso, elas deveriam tratar de questões...

They favor a construction and production of discourses that manifest as multiple "truths" and their representations. In addition, they are spaces that stimulate debate, generate or unfavor the tendencies and, above, bring social discourses that reflect the values and a moral of its participants. In Social Networking Sites the ideal is freedom, and therefore users tend to evaluate and judge an action of others and go beyond the attention that is understood. The purpose of the research was identified and shown as some issues related to morality. Studies justifying studies that explore a "virtual" morality and participate in programs and strategies that promote conscious and responsible use. For such use as a netnography network. It consists of a participatory observational survey, because it allows you to search in a universe that has a fixed rhythm, using the own tools of Facebook, the field diary. The date in the case of annual data to 2017 June of 2018, in the case of the case in the case of big data in the users are the greater data in time. In addition, they can be moral issues, such as: justice, robberies, lies, cooperation, altruism. We know that the feeling of indignation comes when the spectator disapproves of an action that considers a moral good and; in itself a value, and therefore what must be done must also follow the same foundations.

This thesis is devoted to the area of sentiment analysis. Its goal is to discuss and compare various methods applicable to sentiment classification of short texts. When analyzing the described techniques, we will orient ourselves towards the context of social networks. Recently, this type of media became the source of vast amounts of data and the demand for its automatic processing is high. Interesting results have been obtained for clustering used in combination with supervised learning and convolution, which is primarily used for image data.
