Botanical Venice. Trasfigurazioni tra città e natura
No full textThe paper aims to investigate a botanical image of Venice that is the result of a series of morphological, physiological and systematic intersections of the historical, cultural and ecological complexities in the lagoon city. The relationships between botanical traces, urban geographies, and architectural evidence mark the development of Venice, the construction of its memory as a palimpsest, and the establishment of a resilient urban canon
China as a laboratory to renegotiate globalization: Statecraft through the selective exclusion of foreign capital
No full textBuilding on Ilias Alami's invitation to reconceptualize foreign investment screening mechanisms as state tools for renegotiating (post)globalization, this commentary mobilizes China's historical engagement with foreign capital, positioning it as a 'laboratory' for rethinking statecraft amid the transformations of global capitalism. By tracing the genealogy of selective regulatory practices - including the establishment of special economic zones - this analysis underscores how China's 'exceptional spaces' and 'exceptional legal forms' have actively reshaped globalization through the strategic exclusion of foreign capital from critical national sectors. Moving beyond reductionist framings of 'state capitalism' and 'globalization', the commentary foregrounds the layered and contingent processes of valorization and accumulation that characterize contemporary capitalist globalization
Investigating Fairness with FanFAIR: is Pre-Processing Useful Only for Performances?
No full textArtificial Intelligence, and Machine Learning systems in general, are becoming pervasive in our society, from the industry to the public administration. AI can often provide a very efficient means to support decision-making, but it can represent a danger for high-risk applications such as bio-medicine and healthcare. In particular, biased datasets might lead to inaccurate or discriminatory ML systems, undermining the accuracy of their predictions and putting patients' health at risk. FanFAIR is a python tool that provides the community with a semi-automatic tool for datasets' fairness assessment. FanFAIR is designed to integrate qualitative considerations - such as ethics, human rights assessment, and data protection - with quantitative indicators of dataset's fairness, such as balance, the presence of invalid entries, or outliers. In this work, we extend FanFAIR to deal with categorical data, and introduce a new algorithm for outlier detection in the presence of missing values. We then provide a case study on the data collected from COVID patients admitted to pneumology departments in Italy. We show how the successive steps of data cleaning and variable selection improve the indicators provided by FanFAIR. This shows that data cleaning procedures are not only necessary to improve the performance of the machine learning algorithm using the data for learning, but are also a way to improve (a measure of) fairness. Hence, the proposed case study provides an example in which performance and fairness are not in contrast, like it is commonly believed to be, but they improve together

Glossary for Research on Human Crowd Dynamics - 2nd Edition
No full textPedestrian and crowd dynamics involves multiple disciplines, including computer science, engineering, mathematics, physics, bio-mechanics, psychology, social science and more. For effective collaboration between disciplines, researchers need a common understanding of key concepts. To address this challenge, A Glossary for Human and Crowd Dynamics was published six years ago, providing researchers with a valuable reference for cross-disciplinary communication.
We now present the second version, which includes 53 new concepts and 12 revisions from the first glossary, collaboratively developed by 65 contributors from various disciplines and regions around the world through a multi-stage process. This process involved identifying new concepts not covered in the first glossary and suggesting revisions to existing entries, voting on proposed additions and modifications, writing definitions for the selected concepts, and collaboratively revising and editing the entries.
By introducing new terms and refining existing definitions, this glossary aims to facilitate clearer communication, improve conceptual consistency, and support collaboration among researchers working within the field of human and crowd dynamics from diverse perspectives
Review: Popular Culture and the End of Antiquity in Southern Gaul, c. 400–550, by Lucy Grig
No full textLucy Grig’s most recent book is an insightful and rigorous exploration of the cultural dynamics that characterized the late antique period in southern Gaul. Grig, a seasoned scholar of Late Antiquity, deftly navigates the complex interplay between elite and popular culture during a time of profound transformation in the Roman Empire. The book represents the culmination of Grig’s extensive study of popular culture and its wider impact on late antique society, and her work significantly contributes to our understanding of how cultural practices, religious beliefs, and social structures evolved as the Western Roman Empire crumbled and new powers emerged
Uno «stordimento allucinato»: immagini e parole in Giorgio Manganelli
No full textIl presente contributo intende indagare il rapporto tra la scrittura di Giorgio Manganelli e le immagini, attraverso un confronto diretto con alcuni suoi scritti dedicati alle arti visive. Riconoscendo che la struttura metafisica del Discorso dell’ombra e dello stemma è soggiacente al pensiero manganelliano e non solo alla sua concezione teorica della letteratura, si osserva che, al centro dell’attenzione dell’autore e del lettore, in rapporto alla scrittura non c’è la singola immagine prodotta o riprodotta, ma l’immagine mentale, plurale e perennemente mutevole, fantasmatica e numinosa. Gli scritti sulle arti di Manganelli non saranno, dunque, semplicemente da considerare prove ecfrastiche, ma invenzioni letterarie che portano e riportano le immagini dell’arte e dell’esperienza personale, attraverso l’itinerario pseudoteologico tracciato dall’autore, alla loro natura di immagini mentali.This paper aims to investigate the relationship between Giorgio Manganelli’s writing and images, through a direct comparison with some of his writings dedicated to the visual arts. Acknowledging that the metaphysical structure of the Discorso dell’ombra e dello stemma is underlying Manganelli’s thought and not only his theoretical conception of literature, it is observed that at the centre of the author’s and the reader’s attention, in relation to writing, there is not the single image produced or reproduced, but the mental image, plural and always mutable, phantasmic and numinous. Manganelli’s writings on the arts are therefore not simply to be considered as ecphrastic proofs, but as literary inventions that bring and return the images of art and personal experience, through the pseudo-theological itinerary traced by the author, to their nature as mental images
Socio-Political Agents of Welfare and the Reception of ʻSocial Securityʼ, Italy, between 1943 and 1948
No full textThe chapter argues that the circulation of ‘social security’ ideas and programmes in Italy during and just after the Second World War may be studied from a dual perspective that connects global concepts to their bottom-up reception at a national level. This interpretive framework problematizes the transnational making of ‘social security’ by shifting the focus to how Italy’s multilayered mixed economy of welfare adapted global ideas to the Italian context. The corpus of sources comparing proposals from Catholic social associations, trade unions, civil servants and social workers suggests that the reconceptualization of ‘social security’ criss-crossed the social and political spheres. Indeed, this debate reflected a variety of views on the goals and structures of the solidarity bonds that were expected to underpin the post-war democratic political pact and social institutions

Flexible models for coherent estimation of rainfall extremes
No full textIntensity duration frequency (IDF) curves are an essential tool for characterizing the frequency of extreme rainfall events and assessing flood risk. These curves are used to describe the expected frequency of extreme rainfall measured at different durations. To ensure coherent estimates of exceedance probabilities across durations, these curves are subject to adequate shape constraints. Most existing methods employed to estimate IDF curves assume that extreme rainfall accumulations over different durations are independent of each other, but this assumption may not always be valid. This problem is addressed in our work by proposing a Markovian model, which accounts for dependence and is computationally tractable. A simulation study is presented to illustrate the performance of the model and the possible impact of not taking into account the dependence across rainfall durations when estimating IDF curves
