Camorra e mafie di mezzo in alcuni recenti contributi delle scienze sociali
2018
Interacting with the lively debate on petitions and the various forms of appeal to the authorities written in different spatial and temporal contexts, the article deals with the analysis of a group of “discrimination” requests addressed to the General Directorate for Demography and Race by a sample of female Italian citizens qualified as belonging to the “Jewish race” in Autumn 1938. Women’s petitions represented a minority within the broader corpus of requests for derogation from the Anti-Semitic Fascist legislation. They are nonetheless a source of great importance, both to illuminate the relevance of the “discrimination” procedures from the persecuted point of view, and to shed fresh lig…
Game of Thieves and WERW-Kpath: Two Novel Measures of Node and Edge Centrality for Mafia Networks
2021
Real-world complex systems can be modeled as homogeneous or heterogeneous graphs composed by nodes connected by edges. The importance of nodes and edges is formally described by a set of measures called centralities which are typically studied for graphs of small size. The proliferation of digital collection of data has led to huge graphs with billions of nodes and edges. For this reason, we focus on two new algorithms, Game of Thieves and WERW-Kpath which are computationally-light alternatives to the canonical centrality measures such as degree, node and edge betweenness, closeness and clustering. We explore the correlation among these measures using the Spearman’s correlation coefficient …
