The Italian Corporate Network After the "Golden Age" (1972-1983): From Centrality to Marginalization of State-Owned Enterprises
Enterprise and Society, 2012Co-Authors: Alberto Rinaldi, Michelangelo VastaAbstract:This article analyzes the structure of the Italian Corporate Network in the decade that followed the end of the "Golden Age" (1972-83), when the transition from the technological trajectory of the second to that of the third industrial revolution began. The article is based on a large dataset, Imita.db, which contains data on more than thirty-eight thousand Italian joint-stock companies and about three hundred thousand directors, and uses both Network analysis and a prosopographic approach. The main result is that the interval considered was marked by a sharp decrease in the degree of cohesion of the Italian Corporate Network. In 1972, the system was very cohesive and state-owned enterprises were well represented within the most central firms. In 1983, the cohesion of the system had sharply diminished; state-owned enterprises had disappeared from the center and a new private center, hinged on Mediobanca, the only merchant bank operating in the country, had emerged.

State-owned enterprises in the Italian Corporate Network, 1972-1983
2009Co-Authors: Alberto Rinaldi, Michelangelo VastaAbstract:State-owned enterprises pervaded Italian capitalism from the 1930s to 1999. Historians have stressed the relevance of stateowned enterprises to capital-intensive industries, but argued they also might curb private-sector growth. While researchers have mapped the extension of the major Italian state-owned groups, private companies in the Italian Corporate Network remain largely unexplored. We use the interlocking directorates technique to assess Antonio Chiesi’s thesis that in the mid-1970s the Italian Corporate Network was marked by two distinct centers, one stateowned and one private. We base our analysis on Imita.db for 1972 and 1983, using both Network analysis and a prosopographic approach. Contrary to Chiesi’s results using a different sample, in 1972 the Italian Corporate Network was characterized by one large center, comprising both private and state-owned companies. By 1983, however, system cohesion had decreased sharply; stateowned enterprises had disappeared from its center, and the Italian Corporate Network, as Chiesi argued, had two distinct centers.

The Italian Corporate Network, 1952-1983: New Evidence Using the Interlocking Directorates Technique
2008Co-Authors: Alberto Rinaldi, Michelangelo VastaAbstract:The paper explores the structure of the Italian Corporate Network by focusing on the relationships between financial - banks, insurances and holdings - and industrial firms in Italy during the period 1952-83 through the analysis of the interlocks that existed between them. By an interlock is meant the link created between two firms when an induvidual belongs to the board of directors of both. The analysis is based on a database - Imita.db - containing data on over 130,000 directors of Italian joint stock companies for the years 1952, 1960, 1972 and 1983. After showing a descriptive statistics of the companies and the directors included in the database, the paper develops a Network connectivity analysis of the system. This is integrated by a prosopographic study about the big linkers, defined as those directors cumulating the highest number of offices in each benchmark year. The paper confirms that the Italian Corporate Network maintained substantial peculiarities in the period investigated. In particular, it argues that interlocks played an important role in guaranteeing the stability of the positions of control of the major private companies and their connections with State-owned enterprises. In 1952 and 1960, the system, centred on the larger electrical companies, showed the highest degree of cohesion. That centre dissolved after the nationalisation of the electricity industry in 1962 and was replaced by a less strong and cohesive one, hinged on banks, insurances and the major finance companies. At the beginning of the 1980s the centre appeared to have been further reshaped with the marginalisation of state-owned enterprises.

security aspects of scada and Corporate Network interconnection an overview
International Conference on Dependability of Computer Systems, 2006Co-Authors: Paulo Motta S Pires, Luiz Affonso Henderson Guedes De OliveiraAbstract:SCADA (Supervisory Control and Data Acquisition) systems play an important role in industrial process. In the past, these used to be stand-alone models, with closed architecture, proprietary protocols and no external connectivity. Nowadays, SCADA rely on wide connectivity and open systems and are connected to Corporate intranets and to the Internet for improve efficiency and productivity. SCADA Networks connected to Corporate Networks brought some new seecurity related challenges. This paper presents an overview of the security aspects of this interconnection.

The influence of firm, industry and Network on the Corporate social performance of Japanese firms
Asia Pacific Journal of Management, 2007Co-Authors: K. C. O’shaughnessy, Eric Gedajlovic, Patrick ReinmoellerAbstract:We develop and test the thesis that Corporate social performance (CSP) constitutes a socially constructed and shared strategic asset, which is not only influenced by factors specific to a firm, but also by the social performance of firms in its industry and inter-Corporate Network. Using variance decomposition, we analyze data from 130 large Japanese firms and find that both firm-specific and industry-level factors account for significant variance in CSP, but Network-level factors do not.

Router Security Penetration Testing in a Virtual Environment
Advances in Intelligent Systems and Computing, 2017Co-Authors: Christian Scully, Ping WangAbstract:A router is the first line of defense in a typical Network. Improper configurations of the router may lead to various security vulnerabilities. Virtualization provides a safe and self-contained environment for Network simulation and security testing. This paper uses a virtual penetration testing environment to simulate and analyze the two phases of a typical Advanced Persistent Threat (APT): (1) incursion by way of reconnaissance (passive information gathering), and (2) discovery by initial compromise to exploit vulnerabilities found in routers linking a Corporate Network with the untrusted zone of the inherently unsecure World Wide Web.
