Bergamo, Leningrado-San Pietroburgo. Giacomo Quarenghi 1967-2017
No full textQuesto contributo al catalogo del fondo dei disegni di Giacomo Quarenghi (1744-1817), conservati presso l’Accademia Carrara di Bergamo, e fino ad ora mai completamente studiati, mette a fuoco eventi, pubblicazioni e ricorrenze quarenghiane dal primo centenario della nascita dell’architetto bergamasco ad oggi. Il contributo intende proporre un quadro storico dell’attività di ricerca dedicata a Giacomo Quarenghi, grazie alla quale si assistette, nel 1967, all’inizio della collaborazione tra ricercatori russi e italiani che, fino a quel periodo, si erano occupati dell’autore e della sua opera in modo autonomo. Questa collaborazione scientifica ha costruito una significativa sintonia e un rapporto proficuo tra Russia e Italia, dal quale sono scaturiti importanti contributi allo studio dell’architetto bergamasco e della cultura architettonica legata al suo tempo.The contribution to the catalogue provided by the collection of drawings by Giacomo Quarenghi (1744-1817), preserved at the Carrara Academy in Bergamo and until now never fully studied, focuses on events, publications and Quarenghi’s anniversaries, starting from the first centenary of the birth of Bergamo’s architect to date. The contribution intends to propose a historical picture of the research activity dedicated to Giacomo Quarenghi, thanks to which we witnessed, in 1967, the beginning of a collaboration between Russian and Italian researchers who, until then, had worked independently on the author and his work. This scientific collaboration has seen the beginning of a harmonious and a fruitful relationship between Russia and Italy, from which important contributions to the study of Bergamo’s architect and the architectural culture linked to his time have originated

Analysing Trajectories of Mobile Users: From Data Warehouses to Recommender Systems
No full textThis chapter discusses a general framework for the analysis of trajectories of moving objects, designed around a Trajectory Data Warehouse (TDW). We argue that data warehouse technologies, combined with geographic visual analytics tools, can play an important role in granting very fast, accurate and understandable analysis of mobility data. We describe how in the last decade the TDW models have changed in order to provide the user with a more suitable model of the reality of interest and we also cope with the challenge of semantic trajectories. As a use case we illustrate how the framework can be instantiated for realizing a recommender system for tourists
Che cos'è un libro?
No full textA new annotated Italian traslation, by Maria Chiara Pievatolo, of I. Kant, Metaphysik der Sitten, Rechtslehre, § 31, II. Its goal is showing that Kant by "persönliches Recht" did not mean a fundamental right of the person, but simply a right concerning relations among persons. It is sufficient to see Kant's definition of "persönliches Recht" in MdS §18 to realize it.
For this reason, it is a mistake to assert that Kant endorsed intellectual property as a basic human right. From his point of view, the right to publish a book depended only on a personal contract between the author and the publisher
Metajournals. A federalist proposal for scholarly communication and data aggregation
No full textWhile the EU is building an open access infrastructure of archives (e.g. OpenAIRE) and it is trying to implement it in the Horizon 2020 program, the gap between the tools and the human beings – researchers, citizen scientists, students, ordinary people – is still wide. The necessity to dictate open access publishing as a mandate for the EU funded research – ten years after the BOAI - is an obvious symptom of it: there is a chasm between the net and the public use of reason. To escalate the advancement and the reuse of research, we should federate the multitude of already existing open access journals in federal open overlay journals that receive their contents from the member journals and boost it with their aggregation power and their semantic web tools. The article contains both the theoretical basis and the guidelines for a project whose goals are: 1. making open access journals visible, highly cited and powerful, by federating them into wide disciplinary overlay journals; 2. avoiding the traps of the “authors pay” open access business model, by exploiting one of the virtue of federalism: the federate journals can remain little and affordable, if they gain visibility from the power of the federal overlay journal aggregating them; 3. enriching the overlay journals both through semantic annotation tools and by means of open platforms dedicated to host ex post peer review and experts comments; 4. making the selection and evaluation processes and their resulting data as much as possible public and open, to avoid the pitfalls (e. g, the serials price crisis) experienced by the closed access publishing model. It is about time to free academic publishing from its expensive walled gardens and to put to test the tools that can help us to transform it in one open forest, with one hundred flowers – and one hundred trailblazers
PHerc. 817: echi virgiliani e ‘pseudoaugusteismo’

The article aims to offer the reader a revised text of this Latin fragmentary poem, based on the direct examination of the papyrus. A commentary and a discussion about the author are provided
Leveraging feature selection to detect potential tax fraudsters
No full textTax evasion is any act that knowingly or unknowingly, legally or unlawfully, leads to non-payment or underpayment of tax due. Enforcing the correct payment of taxes by taxpayers is fundamental in maintaining investments that are necessary and benefits a society as a whole. Indeed, without taxes it is not possible to guarantee basic services such as health-care, education, sanitation, transportation, infrastructure, among other services essential to the population. This issue is especially relevant in developing countries such as Brazil. In this work we consider a real-world case study involving the Treasury Office of the State of Ceará (SEFAZ-CE, Brazil), the agency in charge of supervising more than 300,000 active taxpayers companies. SEFAZ-CE maintains a very large database containing vast amounts of information concerning such companies. Its enforcement team struggles to perform thorough inspections on taxpayers accounts as the underlying traditional human-based inspection processes involve the evaluation of countless fraud indicators (i.e., binary features), thus requiring burdensome amounts of time and being potentially prone to human errors. On the other hand, the vast amount of taxpayer information collected by fiscal agencies opens up the possibility of devising novel techniques able to tackle fiscal evasion much more effectively than traditional approaches. In this work we address the problem of using feature selection to select the most relevant binary features to improve the classification of potential tax fraudsters. Finding out possible fraudsters from taxpayer data with binary features presents several challenges. First, taxpayer data typically have features with low linear correlation between themselves. Also, tax frauds may originate from intricate illicit tactics, which in turn requires to uncover non-linear relationships between multiple features. Finally, few features may be correlated with the targeted class. In this work we propose ALICIA, a new feature selection method based on association rules and propositional logic with a carefully crafted graph centrality measure that attempts to tackle the above challenges while, at the same time, being agnostic to specific classification techniques. ALICIA is structured in three phases: first, it generates a set of relevant association rules from a set of fraud indicators (features). Subsequently, from such association rules ALICIA builds a graph, which structure is then used to determine the most relevant features. To achieve this ALICIA applies a novel centrality measure we call the Feature Topological Importance. We perform an extensive experimental evaluation to assess the validity of our proposal on four different real-world datasets, where we compare our solution with eight other feature selection methods. The results show that ALICIA achieves F-measure scores up to 76.88%, and consistently outperforms its competitors
Sentiment-enhanced multidimensional analysis of online social networks: Perception of the mediterranean refugees crisis
No full textWe propose an analytical framework able to investigate discussions about polarized topics in online social networks from many different angles. The framework supports the analysis of social networks along several dimensions: time, space and sentiment. We show that the proposed analytical framework and the methodology can be used to mine knowledge about the perception of complex social phenomena. We selected the refugee crisis discussions over Twitter as a case study. This difficult and controversial topic is an increasingly important issue for the EU. The raw stream of tweets is enriched with space information (user and mentioned locations), and sentiment (positive vs. negative) w.r.t. refugees. Our study shows differences in positive and negative sentiment in EU countries, in particular in UK, and by matching events, locations and perception, it underlines opinion dynamics and common prejudices regarding the refugees
The scope of property: why does Kant reject the concept of intellectual property?
No full textAlthough both Fichte and Kant are often included among the intellectual property forerunners, there are at least three outstanding differences between the former and the latter: 1. Fichte bases copyright on the individual originality in the form of expression; Kant does not mention originality at all; 2. Fichte equates copyright with private property; Kant rejects the very possibility of founding the authors' right on a ius reale; 3. Fichte believes that copyright violators deserve the same harsh punishment of thieves. According to Kant, the unauthorized printer should simply compensate all the damages he caused to the author or to his authorized publisher. While Fichte is an intellectual property endorser, Kant is an “enlightened” conservative who supports the Roman law tradition, according to which property applies only to material, touchable things (res quae tangi possunt). He accepts the copyright principle, according to which authors are entitled to decide how to publish their works, but describes it as rights concerning only the relationships among persons. The rights of the publishers, besides, are justified only as long as they help authors to reach the public. Kant's copyright is not property; it has the function to protect authors' freedom to share their texts as they prefer, and to make it easier to communicate them to the public. And, if it has to be seen as a means to foster the publication and the diffusion of texts, its rules should also depend on the prevailing media technology. Kant maintained almost the same copyright theory both in his 1785 essay Von der Unrechtmäßigkeit des Büchernachdrucks and in the Metaphysik der Sitten (1797). In 1797, however, Kant bases property on a possessio noumenon that is different, as a juridical, rational possession, from the physical possession. Why does Kant reject the very concept of an intellectual property while advocating an intellectual theory of property? Answering to such a question could help us the provide a general understanding of the functions and the limits of property in Kant's thought
