  1. By: Antoci Angelo; Sabatini Fabio; Sodini Mauro
    Abstract: Empirical studies have documented a decline in indicators of social participation in the last decades. The responsibility of social disengagement has been often attributed to pervasive busyness and the rising pressure of time. In this paper we argue that computer-mediated interaction, and particularly online networking, can help mitigate this downward trend. We develop a logical framework for assessing the role of the internet in the evolution of social participation. We analyze an economy where agents can develop their social interactions through two main modes of participation, one encompassing both online networking and face to face interactions, and another solely based on physical encounters. We study the interdependence between the rise in the pressure of time and the variation in the relative performance of the two strategies of participation.

    Abstract: Students in a traditional agriculture class were surveyed to learn their perceptions of digital learning objects created by the instructor to improve student problem solving ability. Student assignments and exam scores were compared. The students enrolled in the course with digital learning objects scored higher on exams than a similar section which did not include digital learning objects. However, student performance was mixed with regard to assignment and exam scores for the students who used the digital learning objects.
