Social link recommendation systems, like "People-you-may-know" on Facebook, "Who-to-follow" on Twitter, and "Suggested-Accounts" on Instagram assist the users of a social network in establishing new connections with other users. While these systems are becoming more and more important in the growth of social media, they tend to increase the popularity of users that are already popular. Indeed, since link recommenders aim at predicting users' behavior, they accelerate the creation of links that are likely to be created in the future, and, as a consequence, they reinforce social biases by suggesting few (popular) users, while giving few chances to the majority of users to build new connections and increase their popularity.In this paper we measure the popularity of a user by means of its social influence, which is its capability to influence other users' opinions, and we propose a link recommendation algorithm that evaluates the links to suggest according to their increment in social influence instead of their likelihood of being created. In detail, we give a constant factor approximation algorithm for the problem of maximizing the social influence of a given set of target users by suggesting a fixed number of new connections. We experimentally show that, with few new links and small computational time, our algorithm is able to increase by far the social influence of the target users. We compare our algorithm with several baselines and show that it is the most effective one in terms of increased influence.

Social link recommendation systems, like “People-you-may-know” on Facebook, “Who-to-follow” on Twitter, and “Suggested-Accounts” on Instagram assist the users of a social network in establishing new connections with other users. While these systems are becoming more and more important in the growth of social media, they tend to increase the popularity of users that are already popular. Indeed, since link recommenders aim to predict user behavior, they accelerate the creation of links that are likely to be created in the future and, consequently, reinforce social bias by suggesting few (popular) users, giving few chances to most users to create new connections and increase their popularity. In this article, we measure the popularity of a user by means of her social influence, which is her capability to influence other users’ opinions, and we propose a link recommendation algorithm that evaluates the links to suggest according to their increment in social influence instead of their likelihood of being created. In detail, we give a factor approximation algorithm for the problem of maximizing the social influence of a given set of target users by suggesting a fixed number of new connections considering the Linear Threshold model as model for diffusion. We experimentally show that, with few new links and small computational time, our algorithm is able to increase by far the social influence of the target users. We compare our algorithm with several baselines and show that it is the most effective one in terms of increased influence.

Social distance and social link are important in the relationships between teachers and pupils. This question deserves to be examined with a sociological eye. The aim of this book chapter is to clarify the meaning of the terms (“social distance” and “social link”) and to analyze the influences of the social distance reconfigurations on the behavior of the first towards the second. Based on interviews with secondary school teachers, this chapter aims to show how do the influences of social distance reconfigurations change or not their oral language practices.

Purpose This paper aims to explain a celebrity’s deep resonance with consumers by unpacking the individual constituents of a celebrity’s polysemic appeal. While celebrities are traditionally theorised as unidimensional semiotic receptacles of cultural meaning, the authors conceptualise them here instead as human beings/performers with a multi-constitutional, polysemic consumer appeal. Design/methodology/approach Supporting evidence is drawn from autoethnographic data collected over a total period of 25 months and structured through a hermeneutic analysis. Findings In rehumanising the celebrity, the study finds that each celebrity offers the individual consumer a unique and very personal parasocial appeal as the performer, the private person behind the public performer, the tangible manifestation of either through products and the social link to other consumers. The stronger these constituents, individually or symbiotically, appeal to the consumer’s personal desires, the more s/he feels emotionally attached to this particular celebrity. Research limitations/implications Although using autoethnography means that the breadth of collected data is limited, the depth of insight this approach garners sufficiently unpacks the polysemic appeal of celebrities to consumers. Practical implications The findings encourage talent agents, publicists and marketing managers to reconsider underlying assumptions in their talent management and/or celebrity endorsement practices. Originality/value While prior research on celebrity appeal has tended to enshrine celebrities in a “dehumanised” structuralist semiosis, which erases the very idea of individualised consumer meanings, this paper reveals the multi-constitutional polysemy of any particular celebrity’s personal appeal as a performer and human being to any particular consumer.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This study addresses Lacan's comments on Marx. While much has been done towards reading Marx with psychoanalysis generally, little had has been done to unpack the meaning and extent of Lacan's own statements on Marx. For example, while Lacanian Marxists like Slavoj Zizek have wielded Lacan to great effect in a critique of post-structuralism, they have neglected the full meaning and complexity of Lacan's own stance. What is argued thereby is that Zizek not only omits the discrete knowledge within Lacan's commentary, but misses what I describe as a Lacan's theory of the social. On the one hand, it is commonly known in Lacanian thought that discourse is responsible for making the subject. On the other hand, what is less known is that Lacan defined discourse as that which makes a social link which, in contrast with Marxist thought, introduces a certain affect and materialism premised on discourse itself, commonly known, but also for providing the underlying strata of topology (namely, paradox) requisite for making any social link between subjects. Although less commonly known, we can nevertheless gain new insight into Marx. On the one hand, Lacan concedes Marx's underlying structuralism. On the other hand, Marx fails to see the true source of discourse's origins, the real itself, and consequently fails to see the true efficacy of discourse. He fails to see how discourse, although negative, stands as entirely positive and material in its distinctive effects. Discourse negotiates subjects and their inimitable objects of desire in this singularity itself. This is where true production lies; it is that which precedes any social or economic theory, which are otherwise premised on reality. Lacan rejects reality.

This article develops a theoretical framework for analyzing the role of kinship in entrepreneurship. Kinship, we argue, is a key ingredient of the social and cultural environment of entrepreneurs, and, therefore, essential in understanding how and why entrepreneurship happens. Building on qualitative research conducted among Cambodian Chinese entrepreneurs in Phnom Penh, we define kinship as interpersonal ties grounded in relatedness. We distinguish different categories of kinship ties that involve different levels of relatedness and are used for different aspects of entrepreneurship, and we identify different types of reciprocity and trust as the sociocultural dynamics that buttress kinship involvement in entrepreneurship.
