A simulation of disagreement for control of rational cheating in peer review
2013
Understanding the peer review process could help research and shed light on the mechanisms that underlie crowdsourcing. In this paper, we present an agent-based model of peer review built on three entities - the paper, the scientist and the conference. The system is implemented on a BDI platform (Jason) that allows to define a rich model of scoring, evaluating and selecting papers for conferences. Then, we propose a programme committee update mechanism based on disagreement control that is able to remove reviewers applying a strategy aimed to prevent papers better than their own to be accepted (rational cheating). We analyze a homogeneous scenario, where all conferences aim to the same leve…
Statistically validated mobile communication networks: the evolution of motifs in European and Chinese data
2014
Big data open up unprecedented opportunities to investigate complex systems including the society. In particular, communication data serve as major sources for computational social sciences but they have to be cleaned and filtered as they may contain spurious information due to recording errors as well as interactions, like commercial and marketing activities, not directly related to the social network. The network constructed from communication data can only be considered as a proxy for the network of social relationships. Here we apply a systematic method, based on multiple hypothesis testing, to statistically validate the links and then construct the corresponding Bonferroni network, gen…
Is translation an autopoietic system?
2010
Translation is analyzed from the standpoint of its systemic properties. Translation is shown to have the capacity to observe itself and its difference from the environment. Observation being a major autopoietic factor, translation may be considered as an autopoietic system. Doubts about this hypothesis arise because of the peculiarities of communicative properties of translation. Translation plays the role of the mediating party in complex translation communication events and its communicative behavior is ‘defective’ in that translation does not act upon source messages because its communicative function is passing messages on to the target party. As a system, translation may be studied aga…
A Diffusive Strategic Dynamics for Social Systems
2010
We propose a model for the dynamics of a social system, which includes diffusive effects and a biased rule for spin-flips, reproducing the effect of strategic choices. This model is able to mimic some phenomena taking place during marketing or political campaigns. Using a cost function based on the Ising model defined on the typical quenched interaction environments for social systems (Erdos-Renyi graph, small-world and scale-free networks), we find, by numerical simulations, that a stable stationary state is reached, and we compare the final state to the one obtained with standard dynamics, by means of total magnetization and magnetic susceptibility. Our results show that the diffusive str…
Jessie Bernard. Paradossi dei matrimoni felici e della maternità incondizionata
2022
Questo volume introduce per la prima volta in Italia il pensiero di Jessie Bernard, la cui produzione scientifica sui temi del genere e del femminile – dal matrimonio alla maternità, dalla segregazione alla mobilità professionale – ha fornito un importante contribuito alla rivoluzione femminista, proponendo un’analisi articolata del “sistema coniugale americano” e dei condizionamenti operanti sulle famiglie bianche e su quelle di colore in tema di maternità. Il pensiero di Jessie Bernard non si situa in una lotta ideologica, ma nell’esperienza di una studiosa che ha “scalato le montagne” dell’irrisione coniugale, della sufficienza accademica e del sospetto femminista. Una riflessività – que…
Structure and evolution of a European Parliament via a network and correlation analysis
2016
We present a study of the network of relationships among elected members of the Finnish parliament, based on a quantitative analysis of initiative co-signatures, and its evolution over 16 years. To understand the structure of the parliament, we constructed a statistically validated network of members, based on the similarity between the patterns of initiatives they signed. We looked for communities within the network and characterized them in terms of members' attributes, such as electoral district and party. To gain insight on the nested structure of communities, we constructed a hierarchical tree of members from the correlation matrix. Afterwards, we studied parliament dynamics yearly, wi…
