No full textCooperative Architectures The Italian Way Along e-Government
No full textIn Italy, the need for a better coordination of efforts and investments in the area of government information systems motivated the Italian Parliament in 1993 to create the Authority for Information Technology in the Public Administration. The initiatives undertaken by AIPA include: the definition, design and deployment of a Nationwide Public Administration Network to connect public administrations; and the definition and deployment of a Nationwide Cooperative Information System atop the network to facilitate increased organizational efficiency and effectiveness of administrative actions. In the last few years, some cooperative projects aiming at the development of specific cooperative systems in different areas have been experimenting with different technologies, architectures, and approaches to cooperation. This chapter describes and compares these projects, focusing on the organizational characters of their approaches to cooperation; and it proposes some guidelines for the future Nationwide Cooperative Information Systemof the Italian Public Administration

Coherence maintainance in cooperative information systems: the access key warehouse approach
No full text In this paper, we present and discuss a novel architectural approach supporting the integration among legacy information systems of autonomous organizations. It is based on the use of a data warehouse in a new conceptual role. Namely, we propose to use it, during the design and implementation phases of a cooperative information system, as a tool supporting the coherence maintenance of the underlying databases and the efficient management of accesses to them. Our approach is rooted in the SICC project for cadastral data exchange among Italian Municipalities, Ministry of Finance, Notaries, and Certified Land Surveyors. Research results reported here are an abstraction of solutions introduced in the SICC project and validated through the development of various inter-organization cooperative information systems, managed by the "Coordinamento dei Progetti Intersettoriali" of AIPA, the Italian Authority for Information Technology in Public Administration. </jats:p
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
