In this paper we introduce a new view on roles in Object Oriented programming languages. This view is based on an ontological analysis of roles and attributes to roles the following properties: first, a role is always associated not only with an object instance playing the role, but also to another object instance which constitutes the context of the role and which we call institution. Second, ...

Network Analysis is employed as methodological approach to classify social roles. With this aim, we measure sociometric status by the direct observation of pre-school children behaviours. The data have been collected by a longitudinal observational study. We follow the children in seven waves for two months. In this study, we measure relational skills of subjects applying three procedures. Name...

While it may not be easy for social workers to integrate the roles of investigator and he...

After sign-up and baseline session...

In this paper we propose a foundational ontology of the social concepts of organization and role which structure institutions. We identify which axioms model social concepts like organization and roles and which properties distinguish them from other categories like objects and agents: the organizational structure of institutions and the relation between roles and organizations. All social conc...
