Full textI will propose a theoretical framework (conceptualization and formalization) which seeks to model obesity as a process of transformation of one's own body determined by individual (physical and psychological), inter-individual (relational, relationship between the individual and others) and socio-cultural factors (environmental, relationship between the individual and his milieu). Individual and inter-individual factors are tied to each other in a socio-cultural context whose impact is notably related to the visibility of any body being exposed on the public stage in a non-contingent way. To investigate obesity in this multifactorial manner, this paper is divided in two main parts. First, I take into account these inseparable factors to analyze the impact through time that obese individual transformation may have on the social structure. With this aim, I develop a network model in which individual interactions are in part due to homophilic selection/deselection, i. E. Preferential attachment and detachment of inter-individual links according to characteristics of the individuals involved. Homophily is here defined as the tendency of an individual to create links with other individuals sharing similar attributes with him and to cut links with other dissimilar individuals. Homophily suggests that individuals tend to interact with those who resemble them. Second, and reciprocally, I study the role which could be played by the structure of the social fabric in the increase and current development of obesity. I evaluate the impact of micro level (i. E : relations between individuals) as well as the impact of meso level (i. E : relations between districts) and between macro level (i. E :countries). This approach highlights the necessity to integrate the dynamics of each scale to better understand the evolution of the pathology. With this aim, I use two stochastic models : epidemiological compartmental model and individual centered network model, considering three influences : exogenous heterogeneous (individual- cultural), exogenous homogeneous (individual-social) and endogenous (individual-individual). All together, this investigation of obesity will allow me to investigate the social and cultural dimension involved in being and transforming one's body

Full textThis work aims at contributing to analyze the role of word-of-mouth communication in the job matching process. If employers and job seekers are used to relying on their social relations, the percentage of jobs finally filled through socialnetworks varies between geographical areas. In the first chapter, we analyze, through a matching model of the labormarket à la Pissarides (2000) with social networks, the potential influence of the level of both professional concentration and ethnic diversity in the area. We find that the rise of professional concentration has a positive impact on the distribution of information through contacts. However, if ethnic origin is the single criterion influencing networks formation, it has a negative impact. In the second chapter, we re-evaluate the results of chapter one in an extended theoretical framework: workers have different level of qualification, some employed workers are overqualified and search on-the-job to improve their situation. Our results indicate that on-the-job search has a negative impact on the word-of-mouth communication process. In the third chapter, we show, from the French Trajectories and Origins survey from Ined/Insee (2008) that the rise of ethnic diversity has a positive impact on word-of-mouth communication in the labor market. Still from the same dataset, we find, in chapter four, that job offers provided by contacts are generally not appropriate to workers competences

Full textThe first chapter of this thesis considers an ad-financed media firm that chooses the ideological location of its news and targets consumers who can share the news with their followers on social media. After studying how each targeted consumer's incentive to share the news is shaped by the location of the news and the distribution of her followers’ ideological locations, we study the firm's strategy to maximize the breadth of news sharing and find that when the mean (respectively, the variance) of the followers' ideological locations is a convex (respectively, concave) function of a targeted consumer's location, the firm is likely to produce polarized news.In the second chapter, we consider a monopoly platform providing a continuum of vertically differentiated content and study the design of the optimal screening contracts when consumers have binary types. A contract specifies a set of content, a price and whether or not the content consumption is subject to advertising. We distinguish top-down content allocations from bottom-up allocations and allow for informational bundling of a content set. We find that advertising can induce the platform to use bottom-up allocation for low-type consumers while subscription-based contracts always use top-down allocations. Advertising tends to induce the platform to expand the amount of content consumed by resorting to informational bundling, which increases consumer surplus. When content consumption cannot be subsidized by a negative price, the platform may find it optimal to offer a freemium contract, which expands (reduces) the consumption set, relative to the case of consumption subsidy, for bottom-up allocations (top-down allocations) and thereby increases (reduces) consumer surplus. Finally, when high types experience larger ad nuisance than low types, the platform may have a socially excessive incentive to show advertising to low types in order to extract the information rent of high types.In the third chapter, we study equilibrium patent licensing networks that arise among symmetric competing firms. We consider licensing agreements that cannot specify royalties but can use fixed fees and focus on bilaterally-efficient networks. We find that the complete network, which generates the most competitive outcome is always bilaterally efficient. When there are three symmetric firms, we provide a complete characterization of all bilaterally-efficient licensing networks. When patents are independent, we find that the star network leading to monopoly is never bilaterally efficient. In particular, when the cost reduction from patent is large enough, there is a big contrast: although a multilateral licensing agreement allows the firms to implement the monopoly outcome, the complete network is the unique bilaterally-efficient network. We provide a general condition under which the complete network is both the unique bilaterally-efficient outcome and the unique industry-profit-maximizing outcome for any given number of firms. Our results offer clear-cut policy implications in favor of fixed-fee licensing relative to two-part tariff licensing including royalties

Full textIn the last years, the amount of available data on the social Web has exploded. For the average user, it became hard to find quality content without being overwhelmed with publications. For service providers, the scalability of such services became a challenging task. The aim of this thesis is to achieve a better user experience by offering the filtering and recommendation features. Filtering consists to provide for a given user, the ability of receiving only a subset of the publications from the direct network. Where recommendation allows content discovery by suggesting relevant content producers on given topics. We developed MicroFilter, a scalable filtering system able to handle Web-like data flows and RecLand, a recommender system that takes advantage of the network topology as well as the content in order to provide relevant recommendations
Zardi, Hédia. "Détection des communautés dans les réseaux sociaux dynamiques : une approche multi-agents." Thesis, Paris 6, 2016. http://www.theses.fr/2016PA066147.
Full textAnalysis of social networks has led to the discovery of a very interesting property : these networks are characterized by the existence of areas with high density composed of highly interconnected elements. These areas called "communities", evolve over time according to the dynamic of social members and their interactions. The identification of these communities offers an interesting light on the network structure and it allows to track their progress over time. Although this problem has been the subject of numerous studies in recent years, the detection of dynamic communities remains an open problem and no fully satisfactory solution has yet been proposed. In this work, we propose a multi-agent approach for the detection of communities in dynamic social networks. The entities of our approach observe the evolution of the network and consequently they adapt in real time the graph representing the network and they generate the appropriate changes on previously identified communities. This approach allows to model the network by a graph that dynamically adapts according to the evolution of the network. For this modeling, several network’s aspects are integrated: the topological structure of the graph, the semantic similarity of social members and the communication between them. This modeling is based on the concept of homophily and a pheromone based stigmergy. In order to study the performances of the proposed approach, we applied it to a divers set of real and artificial graphs. The results were satisfactory enough and show the good performance of our model

Full textThis thesis investigates one factor that may differ across men and women and may contribute to their differentlabor market outcomes: social networks. The objective of this work is twofold. On the one hand, it is important tounderstand whether men and women differ in the way they form their social networks. On the other hand, it isnecessary to pay particular attention to how men and women use their social networks for job-related benefits, inorder to understand whether social networks form part of the explanation behind persistent gender differences inthe labor market.The first chapter tries to assess whether men and women differ in terms of their social network formation. It teststwo hypotheses, based on sexual selection theory, about gender differences in individual choices with respect tosocial interactions that require investment (of time or economic resources). The differential selectivity hypothesispredicts that women invest less than men in interactions with new partners, all other things being equal. Thedifferential opportunism hypothesis predicts that women’s investments in social interactions are less responsive toinformation about the likely economic payoff to these investments. Both hypotheses, if true, imply importantdifferences in the formation of social networks by women and men. Evidence is found in support of the twohypotheses, using two cohorts of a total of 363 students that were matched randomly over two rounds withpartners to play trust games.The second chapter investigates whether social networks yield different salary benefits for some 22,000 male andfemale senior executive and non-executive board members in European and US firms. The number of currentlyinfluential individuals with whom executive men have previously worked has a large positive impact on their salary,while the impact for executive women is significantly weaker, and statistically distinguishable from zero only incertain years. These findings also hold for non-salaried remuneration. Using a placebo measure of individuals whowere employed in the same firm as the individuals, but at different times, it is shown that the network measuresreflect genuine connections and not merely unobserved individual characteristics. In contrast to executives, nonexecutiveboard members do not display systematic gender differences in the effectiveness with which theyleverage their links into remuneration. The possible mechanisms at play are explored, and it appears that the firmswhich do the most to integrate women into positions of executive power appear to rely less on networks forrecruitment.The third chapter focuses on the role of social networks in outside board appointments. Using data on US publiclyquoted companies from 2003 to 2012, prior employment links between candidates and the current directors sittingon the board are uncovered by studying the employment history of candidates and board members anddetermining whether they have previously worked together. This works shows that having historical connectionswith board members increases the probability of being appointed as an outside director, and knowing the CEO inparticular increases this probability further. On the contrary, being connected with members of the nominationcommittee in particular does not improve the chances of being appointed to the board above and beyond theeffect of knowing any board member. Future research should determine whether the effect of social networks onoutside board appointments is detrimental or not for firm performance and corporate governance in general

Full textThe emergence of social media has revolutionized the web by allowing individuals to extend their virtual connection in a more real relationship and share knowledge. This new context of information dissemination on the Web can be an effective way to identify the information needs of Web users, and allow information retrieval (IR) to better meet these needs by adapting the indexing and querying models. The information retrieval faced several challenges with the use of social networks, the most important concerns the representation of information in a personalized social IR (PSIR) model and its evaluation in the absence of a social test collections with the user-centered data (user-centered queries and user-centered relevance judgments). We propose to benefit from the use of the user generated content (UGC) on the social networks to personalize his social search in order to better fit his interests and preferences. The main contributions of our work consist of, on the one hand, building a social profile from the UGC within the social network. We propose then a personalized social information retrieval models which integrate the user’s social profile at various levels of the IR process. On the other hand, with the objective of evaluating our PSIR models on a dedicated test collection, we propose a PSIR test collection "DelRSI" we built from the collaborative social bookmarking network "Delicious" ; a PSIR test collection containing in addition to the classical IR test collection’s data, a user-centered data

Full textThe objective of this study is to explore three different techniques to predict toxicity online community users. Our main motivation is to help the moderators of these communities to focus their efforts on users who are more likely to write toxic messages, and thus avoid wasting time and resources by monitoring the entire community. First, we created a mathematical model capable of predicting the five personality traits of the OCEAN model (Openness, Conscientiousness, Extraversion, Agreeableness and Neuroticism) and the three traits of the Dark Triad (Narcissism, Machiavellianism and Psychopathy) for auser, based on their writing style and choice of vocabulary. The experiments we performed with this model on users of the Twitter and Reddit communities have shown that there is a relationship between a user’s personality and the level of toxicity of their messages. In particular, we found that users with high values of narcissism, Machiavellianism and psychopathy andlow values of conscientiousness and agreeableness were more likely to write toxic messages. For our second technique, we applied clustering algorithms on the predicted personality traits andon the observed language characteristics. This allowed us to show that it is possible to detect clusters of potentially risky users without having to create a profile for each user. Finally, we created a regression model to estimate the level of toxicity of users based on their linguistic attributes alone. We observed that the users predicted to have higher toxicity levels by our regression model are also those who have a very high value of Dark Triad traits according to our personality model.
