Motivated by privacy and security concerns in online social networks, we study the role of social pressure in opinion games. These are games, important in economics and sociology, that model the formation of opinions in a social network. We enrich the definition of (noisy) best-response dynamics for opinion games by introducing the pressure, increasing with time, to reach an agreement.We prove that for clique social networks, the dynamics always converges to consensus (no matter the level of noise) if the social pressure is high enough. Moreover, we provide (tight) bounds on the speed of convergence; these bounds are polynomial in the number of players provided that the pressure grows sufficiently fast.We finally look beyond cliques: we characterize the graphs for which consensus is guaranteed, and make some considerations on the computational complexity of checking whether a graph satisfies such a condition.

Social networks like Facebook, Twitter, Pinterest etc. provide data of its users to the demanding organizations to better comprehend the quality of their potential clients. Publishing confidential data of social network users in its raw form raises several privacy and security concerns. Recently, some anonymization techniques have been developed to address these issues. In this paper, a technique to prevent identity disclosure through structure attacks has been proposed which not only prevents identity disclosure but also preserves utility of data published by online social networks. Algorithms have been developed by using noise nodes/edges with the consideration of introducing minimum change in the original graphical structure of social networks. The authors' work is unique in the sense that previous works are based on edge editing only but their proposed work protects against structure attacks using mutual nodes in the social network and the effectiveness of the proposed technique has been proved using APL (Average Path Length) and information loss as parameters.

Online Consumer Behaviour

Despite an increasing interest in understanding consumer behaviour through social media, there is paucity of research concerning psychodynamics among consumers derived by online social networks in emerging economies. The aim of this paper is to explore the role of vloggers (video bloggers) as key network performers to derive consumer psychodynamics (consumers' interactions reflected in a company) through social media, specifically YouTube, through the lens of the experiential view and the Social Network Theory. This work will contribute to the extant literature by determining (1) the relevance of the experiential view approach in online social networks' performance, (2) how psychodynamics among consumers are conducted through social media, specifically YouTube, and (3) how key network performers as YouTube's vloggers derive psychodynamics among consumers. Using an inductive approach and grounded theory to analyse the results, the research findings provide a more comprehensive understanding of online consumer behaviour, therefore, yields more valuable information by examining the experiential view in a digital environment.

Using survey data of social media users in South Korea, this study investigates the dynamics of political rumors in online social networks. Findings of this study reveal the significant connection between the users’ reliance on social media as a source for news and their beliefs in political rumors. Taking a step further, this study underscores the need to understand how users process misinformation they receive through online social networks. Drawing attention to the role of network characteristics in the construction of beliefs around political rumors, this study provides a more nuanced understanding of the conditions under which rumors and misinformation can be regarded as more believable.

This paper develops the theory of the social contagion of violence by proposing a four-part analytical framework that focuses on: (1) contagious narratives and the accompanying behavioural script about the use of violence as a response to those narratives; (2) population susceptibility to these narratives, in particular the role of worldviews and the underlying emotional landscape; (3) mechanisms of transmission, including physical and online social networks, public displays of violence and participation in violence; and (4) the role of contagion entrepreneurs. It argues that a similar four-part approach can be used to identify and imagine possibilities of counter-contagion. The application of the theory is illustrated through examination of the recent epidemic of violence against individuals accused of practising sorcery in the Enga province of Papua New Guinea, a place where such violence is a very new phenomenon.

Definition Of

Taking an anthropological approach, this article interprets Pagnol's critically acknowledged classic as a reinvention of a carnivalesque ritual practised in France from the late middle ages through the late 1930s, when ethnographers observed its last vestiges. By linking La Femme du boulanger (The baker's wife, 1938) to contemporaneous debates over gender, national decadence, and the definition of French cultural identity, I argue that the film recycles the charivari's long-standing function as a tool of popular protest against social and political practices regarded as detrimental to the welfare of the nation. In the context of the Popular Front, Pagnol's charivari ridiculed divisive partisan politics pitting Left against Right, symbolically purged class conflict from the social body, and created a new form of folklore that served as a focal point for the communitarian ritual of movie-going among the urban working and middle classes. In so doing, the film promoted the ongoing shift in public support away from the Popular Front in favour of a conservative ‘National Union’ government under Prime Minister Edouard Daladier, who in 1938–9 assumed the role of France's newest political patriarch.

The subject of this research is the specifics, forms and functions of interaction in social media groups between the representatives of ethnic communities. The goal consists in determination of the role of social networks in adaptation of ethnocultural communities of St. Petersburg. The research is based on the polling technique for acquisition of information on the cognitive, emotional, and behavioral state of a person. The survey was conducted via distribution of questionnaires among the representatives of ethnic groups. The article also employs the method of systematic scientific observation over the social media groups, topic raised therein, as well as reading and analysis of the comments. The scientific novelty of this work consists in outlining of the nature, trends and development prospects of cross-cultural communications as the channel for ethnocultural interaction.  The main conclusions, which touch upon users from various ethnic communities who do not have enough experience in organization of activity of social media groups, demonstrate that it causes the loss of the sense of security, accumulation of prejudices and escalation of interethnic conflicts, as well as preference of the with restricted access, which contributes to lock down of the group and impedes adaptation in the accepting society. Stabilization of situation can be achieved by improvement of the quality of content posted in the social media, as well as level of their administration.

The advent of online social networks (OSN) has transformed a common passive reader into a content contributor. It has allowed users to share information and exchange opinions, and also express themselves in online virtual communities to interact with other users of similar interests. However, OSN have turned the social sphere of users into the commercial sphere. This should create a privacy and security issue for OSN users. OSN service providers collect the private and sensitive data of their customers that can be misused by data collectors, third parties, or by unauthorized users. In this paper, common security and privacy issues are explained along with recommendations to OSN users to protect themselves from these issues whenever they use social media.

Flow Of Information

This article introduces a new method to discover the role of influential people in online social networks and presents an algorithm that recognizes influential users to reach a target in the network, in order to provide a strategic advantage for organizations to direct the scope of their digital marketing strategies. Social links among friends play an important role in dictating their behavior in online social networks, these social links determine the flow of information in form of wall posts via shares, likes, re-tweets, mentions, etc., which determines the influence of a node. This article initially identities the correlated nodes in large data sets using customized divide-and-conquer algorithm and then measures the influence of each of these nodes using a linear function. Furthermore, the empirical results show that users who have the highest influence are those whose total number of friends are closer to the total number of friends of each node divided by the total number of nodes in the network.
