A standard optimal investment model can be used to analyse an individual’s decision to accumulate social capital. We analyse six facts that support the predictions of this individualbased approach: (1) social capital first rises and then falls with age, (2) social capital declines with expected mobility, (3) social capital rises in occupations with greater returns to social skills, (4) social c...

The aim of this paper is to provide a logical framework for the specification of autonomous Multi-Agent Systems (MAS). A MAS is autonomous in so far as it is capable of binding (‘nomos’) itself (‘auto’) independently of any external normative constraint specified by a designer. In particular, a MAS is autonomous if it is able to maintain its social institutions (i.e. rule-governed social practi...

From early childhood, human beings learn not only from collections of facts about the world but also from social contexts through observations of other people, communication, and explicit teaching. In these contexts, the data are the result of human actions-actions that come about because of people's goals and intentions. To interpret the implications of others' actions correctly, learners must...

In this paper I show that social knowledge does not supervene on facts about what individuals know, nor even what they believe or intend, or any combination of these or other mental (including epistemic) states. Instead I develop the idea that social knowing is an anal...

This article conceptualizes and elaborates what constitutes learning experiences. It does so from a perspective that centres on experiences as arising through relations between social and personal worldsyet also acknowledges the mediation of brute facts (i.e., nature). The social contributions are twofold, yet quite distinct. First, there are immediate social experiences that are projected by t...

BACKGROUND As online social media have become prominent, much effort has been spent on identifying users with depressive symptoms in order to aim at early diagnosis, treatment, and even prevention by using various online social media. In this paper, we focused on Facebook to discern any correlations between the platform's features and users' depressive symptoms. This work may be helpful in tryi...

Monkeys recognize when they are being imitated, but they seem unable to learn by imitation. These facts make sense if imitation is seen as two different capacities: social mirroring, when actions are matched and have social benefits; and learning by copying, when new behavioural routines are acquired by observation.
