Inspired by infectious disease dynamics and modern psychology, this paper aims at constructing a multi-dimensional function to get the model of information dissemination on social networks under epidemic-related panic base on the characteristics of individual differences and global characteristics, like emotional cumulative effect, herd effect, time-sensitive decline effect, cognitive level, intimacy, personal influence, etc. The results show that the psychological effect has a significant effect on the increase of the spread of panic news; When netizens are in an emotional atmosphere, their emotional self-regulation ability is limited; when the infection rate is relatively low, the characteristics of individual differences play a leading role in affecting the spreading process. When the infection rate is high enough, the herd effect and emotional cumulative effect play a major role in promoting information dissemination; In a society with a higher rate of emotional contact, it is easier to form a kind of collective wisdom, which can help the collective quickly identify rumors. Moreover, in this kind of society, the role of opinion leaders is limited, and timely refutation of rumors can significantly reduce the spread of panic news.

Nous interrogeons les formes d’interactions des apprenants dans un parcours d’autoapprentissage guidé en langues. Le dispositif comprend un centre de ressources en langues, des entretiens et un journal de bord réflexif sur leurs activités dont certaines visent des interactions : tandem, réseaux sociaux, etc. À partir de questionnaires et d’extraits de journaux de bord, nous proposons une typologie des interactions qui nous conduit d’une part à interroger les apprentissages formels, non formels ou informels, d’autre part à relier ces interactions aux différentes catégories de l’autonomisation : autodirection, planification et choix des ressources, autorégulation et choix des stratégies, autoévaluation.We analyze the way interactions take place among learners in a self-directed language learning environment. It gathers a language learning centre, individual interviews and a reflexive learning journal describing their activities, which may include interactions such as tandem, social networks, etc. We rely on questionnaires and learning journal extracts that help us build a typology of interactions. This leads us to discuss the notion of formal, informal and non-formal learning and to associate these interactions with several categories for the development of autonomy: self-direction, planning and choosing resources, self-regulation and choice of strategies and self-evaluation.

Reduced Activity

Testosterone plays a role in aggressive behavior, but the mechanisms remain unclear. The present study tested the hypothesis that testosterone influences aggression through the OFC, a region implicated in self-regulation and impulse control. In a decision-making paradigm in which people chose between aggression and monetary reward (the ultimatum game), testosterone was associated with increased aggression following social provocation (rejecting unfair offers). The effect of testosterone on aggression was explained by reduced activity in the medial OFC. The findings suggest that testosterone increases the propensity toward aggression because of reduced activation of the neural circuitry of impulse control and self-regulation.

Opinion Evolution

We study opinion dynamics in social networks and present a new strategy to control the invasive opinion. A developed continuous-opinion evolution model is proposed to describe the mechanism of making decision in closed community. Two basic strategies of evolution are determined, and some basic features of our new model are analyzed. We study the different invasive strategies. It is shown via using Monte Carlo simulations that our new model shows different invulnerability with traditional model. Node degree and cohesion in invasive small-world community plays less significant role when the evolution of opinion is continuous rather than dichotomous. Using simulation, we find one kind of Influential Nodes that can affect the outcome dramatically, while these Influential Nodes are sensitive to their node degree and the evolution weight. Thus, we develop invasive control strategy based on these features.

This work proposes a new model of activation of frames, called network activated frames (NAF). The NAF seeks to update the study of framing as a result of the activation of frames by users in a connected network. With this objective in mind, I reconstruct the different notions of frame and framing in the political communication literature and present their limitations. The activation of frames in social networks is verified experimentally using a conjoint experiment, a technique that randomly rotates a variety of frame elements and evaluates the intention to share the content. The results provide conclusive evidence of the propensity of social network users to activate different frame elements in different regions of a social network. Resumen Este trabajo propone un nuevo modelo de activación de encuadres llamado network activated frames (NAF) (activación de encuadres en red). El NAF busca actualizar el estudio del framing como resultado de la activación de encuadres por parte de los usuarios en una red conectada. Con este objetivo en mente, reconstruyo las distintas nociones de frame y framing en la bibliografía en comunicación política y presento sus limitaciones. La activación de encuadres en redes sociales se constata experimentalmente utilizando tweets apareados (conjoint experiment), una técnica que rota aleatoriamente una variedad de elementos de encuadre (frame elements) y evalúa la intención de compartir el contenido. Los resultados proporcionan evidencia concluyente de la propensión de los usuarios de redes sociales a activar distintos elementos de encuadre en distintas regiones de una red social.

Purpose ”“ The purpose is to examine the degree of privacy protection in the social networking field. In this sense, we analyze the benefits of the self-regulation of the industry as a complement to the regulations. Methodology/approach/design ”“ We study the Spanish and the European regulations regarding personal data protection with respect to social networks. Findings ”“ The legislative regulations on this subject are insufficient due to their intrinsic limitations in the field. Therefore, we should encourage the approval of good legislation that complements and fills the gaps. Practical implications ”“ The advantages that are derived from the research on this subject are useful for service providers and the public and private sectors in the information society. Therefore, they are useful for society in general. Originality/value ”“ This research article includes the examination of the general utility of society. The aspects that are addressed are applicable to the industry and those who use social networks. The government must prevent infractions that damage consumers and/or users.
