Supervised and Semi-Supervised Explainable AI applied to Cardiovascular Magnetic Resonance Mapping Techniques
No full textDeep Learning techniques have demonstrated broad applicability across numerous domains, including medicine. Among these, Cardiovascular Magnetic Resonance Imaging stands out as a field where Deep Learning has the potential to transform myocardial tissue characterization through the automated, objective, and reproducible assessment of modern-day quantitative techniques like T1 and T2 mapping images, which serve as the case study of this Thesis. The clinical implementation of these techniques, however, is hindered by several obstacles, including the need for center-specific reference values -- which strongly depend on the magnetic field strength, acquisition sequence, and chosen parameters -- along with the scarcity of large annotated datasets, class imbalance, and the requirement for transparent and explainable decision-making. This Thesis proposes a Deep Learning approach that utilizes supervised and semi-supervised learning and model ensembling to navigate some of these challenges. It provides explainability tools to support transparent case-level explanation of model predictions, facilitate clinician trust and supporting clinical adoption. Experimental results demonstrate that the proposed framework enhanced predictive accuracy and reliability harnessing actionable insights in Cardiac Imaging
Gli impatti macroeconomici delle politiche per il clima in Italia
No full textQuesto articolo fornisce alcuni risultati quantitativi sull’efficacia e sugli impatti macroeconomici delle politiche di accompagnamento alla transizione verso le zero emissioni. Una delle critiche più requenti mosse infatti a chi sottolinea l’urgenza di agire per ridurre le emissioni di gas serra è il costo di queste politiche e la necessità di evitare che i loro impatti riducano crescita economica e occupazione. Ma il costo dipende fortemente, come vedremo, dalle politiche adottate: politiche di accompagnamento ben disegnate sono in grado di ridurre fortemente, se non azzerare, i costi della transizione. Almeno in aggregato, perché questa transizione, come tutte le altre di questi ultimi 150 anni, sta avendo e avrà importanti effetti distributivi. Per cui le politiche vanno pensate e applicate sia per ridurre il costo aggregato della transizione, anche nel breve periodo, sia per attenuare i loro effetti distributivi (settoriali e occupazionali) affinché la transizione sia equa e sorretta dal consenso degli elettori
EXPLORING THE INFLUENCE OF SUSTAINABILITY AND DIGITALIZATION ON BRAND IDENTITY IN THE LUXURY INDUSTRY. THE BULGARI CASE.
No full textIn the present dynamic landscape, the luxury industry is undergoing a significant transformation, characterized by the emergence of new trends that compel brands to swiftly adapt to the accompanying challenges. The work sets as its main object of analysis two prevailing emerging trends, sustainability and digitalization, as they majorly reflect the evolving preferences and needs of the younger generations, and on the impact these phenomena have on luxury brand identity, with a particular focus on the case study of the renowned Roman Maison, Bulgari. The case study analyses strategies and practices adopted by the Maison, along with an assessment of their impacts on both
brand identity and image and the major challenges that Bulgari faces in navigating these transformative processes

Ultrafast Terahertz Field Control of the Emergent Magnetic and Electronic Interactions at Oxide Interfaces
No full textUltrafast electric-field control of emergent electronic and magnetic states at oxide interfaces offers exciting prospects for the development of the next generation of energy-efficient devices. Here, it is demonstrated that the electronic structure and emergent ferromagnetic interfacial state in epitaxial LaNiO3/CaMnO3 superlattices can be effectively controlled using intense, single-cycle THz electric-field pulses. A suite of advanced X-ray spectroscopic techniques is employed to measure a detailed magneto-optical profile and the thickness of the ferromagnetic interfacial layer. Then, a combination of time-resolved and temperature-dependent optical measurements is used to disentangle several correlated electronic and magnetic processes driven by ultrafast, high-field THz pulses. Sub-picosecond non-equilibrium Joule heating of the electronic system is observed, ultrafast demagnetization of the ferromagnetic interfacial layer, and slower dynamics indicative of a change in the magnetic state of the superlattice due to the transfer of spin-angular momentum to the lattice. These findings suggest a promising avenue for the efficient control of 2D ferromagnetic states at oxide interfaces using ultrafast electric-field pulses
Clitic climbing across Italy. Variation, optionality, and the role of bilectalism
No full textThis study discusses clitic placement in restructuring contexts in Italian and the Italo-Romance dialects spoken in Italy. The data come from AIS map 1086 and a judgement task experiment conducted on bilectal speakers of Italian and the dialect at six representative points in the Italian territory. The variation between clitic climbing and enclisis turns out to be much more complex than previous literature has suggested. The two clitic positions are available to all varieties, but at different rates and with different degrees of optionality. Optionality can be analysed as a function of language dominance in an intricate fashion
Does Being a HERO Really Make a Positive Difference to Police Officer Street Level Bureaucrats’ Well-Being?
No full textThis study examines the extent to which being a HERO (i.e., Hope, Efficacy, Resilience, and Optimism) impacts police officer Street Level Bureaucrats (SLBs) operational and organizational stress, and their subsequent perceived well-being. The sample comprised 220 Italian and 228 English SLBs, and hypotheses were tested using the Analysis for Moment Structures (AMOS) v.27 Structural Equation Modeling software. The findings depict that HERO explains approximately a fifth of SLBs’ organizational stress, and together, their variance accounted for approximately two-thirds of SLBs’ well-being. Finally, as one personal psychological resource for helping police officers cope with stress in the workplace, the findings indicate a need to upskill SLBs in HERO to better negotiate bureaucratic processes without becoming more susceptible to negative stress-related outcomes
