Per un museo virtuale dell'informatica. Un supporto automatico per creare "visite museali"

The subject of the present research is related to the field of computer technology applied to support intellectual activities such as text translation, screenwriting and content organization of popular and education courses, especially concerning museum visits. The research has started with the deep analysis of the cognitive process which characterizes a screenwriter while working. This choice has been made because a screenplay is not only an aid to the realization of a show but, more in general, it can be considered as the planning of an education, popular and formative intellectual activity. After this analysis, the research has focused on the specific area of the planning, description and introduction of topics related to the history of science, and in particular, of computer science. To focus on this area it has been fundamental to analyse subjects concerning the didactics of museum visits organization. The aim was to find out the guide lines that a teacher should follow when planning the visit of a museum (virtual museum of the history of computer science). The consequent designing and realisation of an automatic support system for the description and the production of a formative, education and popular multimedia product (for the history of computer science), has been possible thanks to the results achieved through this research. The system obtained is provided by the following features: ·management of multimedia slides (such as texts, video, audio or images) which can be classified on the bases of the topic and of the profile of the user; ·automatic creation of a sequence of multimedia slides which introduce the topic; ·management of the interaction with the user to check and give validity to the product. The most innovative aspect of the present research is represented by the fact that the product is realised on the bases of the profile of the user.

The social construction of cooperation: exchange, identification and collective intentions within the organization

My aim is to develop a theory of cooperation within the organization and empirically test it. Drawing upon social exchange theory, social identity theory, the idea of collective intentions, and social constructivism, the main assumption of my work implies that both cooperation and the organization itself are continually shaped and restructured by actions, judgments, and symbolic interpretations of the parties involved. Therefore, I propose that the decision to cooperate, expressed say as an intention to cooperate, reflects and depends on a three step social process shaped by the interpretations of the actors involved. The first step entails an instrumental evaluation of cooperation in terms of social exchange. In the second step, this “social calculus” is translated into cognitive, emotional and evaluative reactions directed toward the organization. Finally, once the identification process is completed and membership awareness is established, I propose that individuals will start to think largely in terms of “We” instead of “I”. Self-goals are redefined at the collective level, and the outcomes for self, others, and the organization become practically interchangeable. I decided to apply my theory to an important cooperative problem in management research: knowledge exchange within organizations. Hence, I conducted a quantitative survey among the members of the virtual community, “www.borse.it” (n=108). Within this community, members freely decide to exchange their knowledge about the stock market among themselves. Because of the confirmatory requirements and the structural complexity of the theory proposed (i.e., the proposal that instrumental evaluations will induce social identity and this in turn will causes collective intentions), I use Structural Equation Modeling to test all hypotheses in this dissertation. The empirical survey-based study found support for the theory of cooperation proposed in this dissertation. The findings suggest that an appropriate conceptualization of the decision to exchange knowledge is one where collective intentions depend proximally on social identity (i.e., cognitive identification, affective commitment, and evaluative engagement) with the organization, and this identity depends on instrumental evaluations of cooperators (i.e., perceived value of the knowledge received, assessment of past reciprocity, expected reciprocity, and expected social outcomes of the exchange). Furthermore, I find that social identity fully mediates the effects of instrumental motives on collective intentions.
