Seed Activation Scheduling for Influence Maximization in Social Networks
2018
This paper addresses the challenge of strategically maximizing the influence spread in a social network, by exploiting cascade propagators termed “seeds”. It introduces the Seed Activation Scheduling Problem (SASP) that chooses the timing of seed activation under a given budget, over a given time horizon, in the presence/absence of competition. The SASP is framed as a blogger-centric marketing problem on a two-level network, where the decisions are made to buy sponsored posts from prominent bloggers at calculated points in time. A Bayesian evidence diffusion model – the Partial Parallel Cascade (PPC) model – allows the network nodes to be partially activated, proportional to their accumulat…
The Impact of Internet and Social Media Use on Well-Being
2021
The present research examines the longitudinal average impact of frequency of use of Internet and social networking sites (SNS) on subjective well-being of adolescents in Germany. Based on five-wave panel data that cover a period of nine years, we disentangle between-person and within-person effects of media use on depressive symptomatology and life satisfaction as indicators of subjective well-being. Additionally, we control for confounders such as TV use, self-esteem, and satisfaction with friends. We found that frequency of Internet use in general and use of SNS in particular is not substantially related subjective well-being. The explanatory power of general Internet use or SNS use to p…

The Open Dialogue Approach to Acute Psychosis: Its Poetics and Micropolitics
2003
In Finland, a network-based, language approach to psychiatric care has emerged, called "Open Dialogue." It draws on Bakhtin's dialogical principles (Bakhtin, 1984) and is rooted in a Batesonian tradition. Two levels of analysis, the poetics and the micropolitics, are presented. The poetics include three principles: "tolerance of uncertainty," "dialogism," and "polyphony in social networks." A treatment meeting shows how these poetics operate to generate a therapeutic dialogue. The micropolitics are the larger institutional practices that support this way of working and are part of Finnish Need-Adapted Treatment. Recent research suggests that Open Dialogue has improved outcomes for young peo…

Social Networks and Labour–Education Market System
2015
Two facts about human beings are widely accepted: they are social creatures and they behave in a bounded rational way. In particular, this results in substantial use of social networks in individual decision-making. Before dealing with the issues of modelling individual behaviour in the labour–education market system, we have to recall some empirical facts known from the literature about this behaviour. This is exactly what this chapter provides.
