La pantomima italiana sulla scena americana ottocentesca. Lo spettacolo come prodotto del mercato dell’intrattenimento
No full textIl contributo intende documentare l’attività artistica di Marietta Zanfretta, attrice, ballerina e acrobata italiana, che intorno agli anni Cinquanta dell’Ottocento migra negli Stati Uniti. Grazie all’analisi del variegato repertorio dell’artista, delle sue molteplici collaborazioni con celebri compagnie di pantomimi (Ravel), circhi (Van Amburgh) e impresari di rilievo (Tony Pastor), e delle sue costanti tournée in spazi scenici polivalenti (Niblo’s e Bowery Theatre di New York), lo studio storiografico delinea il panorama dello spettacolo dell’epoca post secessionista, in relazione sia ai processi di trasmissione e stabilizzazione delle forme sceniche miste di derivazione europea, sia all’origine del mercato dell’intrattenimento moderno
Shift to the core: Abnormal core-periphery global topography in unipolar and bipolar depression
No full textThis study explores the global signal topography of core and periphery brain networks in Major Depressive Disorder (MDD), Bipolar disorder (BD-Dep) and healthy controls (HC) using resting-state fMRI. In a sample of 140 depressed MDD and BD patients, and 70 HC, we observed a significant shift toward increased activity in the transmodal-core regions (e.g., default mode network, frontoparietal network) at the expense of unimodal-periphery regions (e.g., visual, sensory-motor cortices) in both depressed MDD and BD patients compared to HC. Whole brain machine learning analyses further demonstrated that altered global signal dynamics can effectively distinguish MDD and BD from HC (ACC = 79% and 77% respectively). Notably, we identified a significant negative correlation between global signal correlation in unimodal-periphery networks and depressive symptom severity. Additionally, in a smaller sample of BD during mania (N = 22) a distinct topographic pattern was observed, with increased global representation in the unimodal-periphery compared to depressive states, suggesting mood state-dependent shifts in network organization. To assess multivariate discriminability across diagnostic groups, a Partial Least Squares (PLS) analysis revealed that higher Core and related network activity (DMN, FPN) predicted diagnostic assignment to MDD and BD-Dep, whereas higher Periphery and related network (e.g., visual and sensory-motor networks) predicted assignment to BD-Man and HC. The Core–Periphery (C–P) ratio emerged as the strongest predictor (VIP = 1.65). These results underscore the critical role of global signal topography in mood disorders, particularly the imbalance between core and peripheral brain networks, as a potential neurobiological marker for depressive states
Design, Testing and Calibration of the GAPS Experiment Si(Li) Tracker Readout ASIC: From the First Flight Campaign Toward the Second Mission Upgrade
No full textIl General Antiparticle Spectrometer è un esperimento a pallone stratosferico concepito per effettuare tre voli di lunga durata dall’Antartide, con l’obiettivo di ricercare antinuclei cosmici a bassa energia, in particolare antideuteroni, come canale indiretto per lo studio della materia oscura. La tecnica di rivelazione si basa sulla formazione e sul decadimento di atomi esotici, riconoscibili attraverso l’emissione di raggi x caratteristici e la successiva annichilazione in particelle secondarie. Al cuore dello strumento si trova il tracciatore al silicio, costituito da rivelatori al silicio drogati al litio, operati a –40°C e letti da un circuito integrato dedicato, denominato SLIDER32, realizzato in tecnologia CMOS a 180 nm. La tesi descrive le attività di integrazione, calibrazione e validazione dell’elettronica di lettura del tracciatore basata su SLIDER32. La caratterizzazione in laboratorio di un modulo del tracciatore, condotta con una sorgente di Americio-241 e con muoni cosmici, è stata affiancata da prove di calibrazione e test dell’intero tracciatore nella configurazione prevista per il primo volo, che hanno portato alla prima acquisizione di uno spettro a raggi x da una sorgente di Cadmio-109. Queste attività hanno fatto parte della fase di integrazione e test dell’esperimento, culminata con l’assemblaggio completo dello strumento e la sua validazione durante la campagna antartica del 2024. Sulla base di questa esperienza è stato progettato e realizzato un nuovo circuito integrato, sviluppato come evoluzione di SLIDER32: il chip ANTARES4, fabbricato in tecnologia CMOS a 65 nm. Il dispositivo integra otto canali analogici fino allo stadio di shaping e introduce soluzioni innovative per la compressione dinamica del segnale mediante transistori MOS a soglia dinamica, insieme a un circuito migliorato di compensazione della corrente di leakage all’ingresso del preamplificatore. La caratterizzazione di laboratorio ha fornito una prima validazione di queste soluzioni progettuali, ponendo le basi per il sistema di lettura di nuova generazione che sarà impiegato nel secondo volo dell’esperimento.The General Antiparticle Spectrometer is a balloon-borne experiment designed to perform three long-duration flights from Antarctica to search for low-energy cosmic antinuclei, in particular antideuterons, as an indirect probe of dark matter. Its detection method is based on the formation and decay of exotic atoms, identified through the emission of characteristic x-rays and the subsequent annihilation into secondary particles. At the core of the instrument is the silicon tracker, composed of lithium-drifted silicon detectors operated at −40°C and read out by a custom application-specific integrated circuit, SLIDER32, implemented in 180 nm CMOS technology. This thesis reports on the integration, calibration, and validation of the SLIDER32-based tracker readout electronics. Laboratory characterization of a single tracker module with an Americium-241 source and cosmic muons was complemented by calibration and testing of the full tracker in its flight configuration, leading to the first x-ray spectrum acquisition from a Cadmium-109 source. These activities formed part of the integration and testing phase of the experiment for the first flight, which culminated in the complete instrument assembly and validation during the Antarctic campaign of 2024. Building on this experience, the work introduces the design and characterization of a new prototype integrated circuit conceived as an upgrade to SLIDER32: the ANTARES4 chip, fabricated in 65 nm CMOS technology. The device integrates eight analog channels up to the shaping stage and implements innovative solutions for dynamic signal compression exploiting dynamic-threshold MOS transistors, together with an improved detector leakage current compensation circuit at the preamplifier input. Its laboratory characterization provides a first validation of these design choices, laying the foundations for the next-generation tracker readout system to be adopted in the second flight of the experiment
Let’s Talk Stigma Out: An Interaction-Based Process of Stigma Recognition and Removal within Organizational Fields
Full text linkStigma is relational and intersubjective, as it depends on how stigmatizing audiences and stigmatized actors make sense of it. However, little research has investigated the nuances of the interaction process through which stigma comes to be recognized and eventually removed. We address this puzzle by studying stigma in the field of cooperatives in the Lazio region of Italy. Following the involvement of one cooperative in illegal activities, cooperatives in the region were stigmatized by its exchange partners: nonprofit organizations and local governments. Cooperatives’ initial strategy to remove stigma led their exchange partners to change their perception of the root causes of the stigma affecting cooperatives. Cooperatives recognized this change through interaction with their exchange partners and therefore adapted their stigma-related strategy. This process successfully removed the stigma and transformed the way in which cooperatives engaged in exchanges with their partners. Building on this evidence, we develop an interaction-based process model of stigma recognition and removal that reconnects and extends the research streams on stigma and organizational fields

Full text linkAutonomia dell’ordinamento sportivo e principi dello Stato di diritto europeo: le questioni pregiudiziali del TAR Lazio nelle cause FIGC-CONI
Full text linkThis article examines the preliminary references submitted by the Lazio Regional Administrative Court (TAR Lazio) in the joint cases FIGC-CONI (C-424/24 and C-425/24), concerning the compatibility of the Italian system of sports justice with EU law. It analyses Advocate General Spielmann’s Opinion on the relationship between sporting autonomy and the principle of effective judicial protection under Articles 19(1) TEU and 47 of the Charter of Fundamental Rights.
The contribution focuses on three issues: the limits imposed on national courts’ powers to review and annul sports disciplinary sanctions; the compatibility of long-term bans with EU rules on competition and free movement; and the question, left open by the Advocate General, of whether broadly framed disciplinary clauses based on duties of loyalty, fairness and probity comply with the principles of legality and due process.
The article situates the FIGC-CONI cases within the recent case-law of the Court of Justice, highlighting the increasing relevance of EU constitutional standards in the assessment of sports regulation
Eco-Design for Additive Manufacturing (EcoDAM)
No full textThe EcoDAM (Eco-Design for Additive Manufacturing) project presents a comprehensive framework aimed at enhancing the environmental sustainability of metal additive manufacturing (AM) processes. Recognizing the complex interdependencies between material selection, manufacturing technologies, and lightweight design, the framework integrates four key steps: sustainable technology selection, lightweight design optimization, and a two-phase parametric life cycle assessment (LCA) involving both objective function formulation and constraint definition. Innovative methodologies such as function-oriented patent analysis, topological and lattice structure optimization, and parametric LCA modelling are employed to systematically evaluate and minimize environmental impacts throughout the AM product lifecycle. A case study based on Ti6Al4V connecting rod produced by laser powder bed fusion demonstrates the application of the framework, resulting in more than 50% weight reduction and improved sustainability performance. Key parameters, such as cell size and wall thickness of gyroid lattice structures, are optimized using finite element modelling simulations, while LCA constraints are formulated using experimental and literature-based data. The framework’s modular design allows for industrial integration using commercial tools, enabling scalable, data-driven, and environmentally informed decision-making in AM. EcoDAM thus contributes a robust methodology for advancing circular economy goals in industrial AM
