No full textIl management delle organizzazioni tra problem solving e decision making
No full textObiettivi. Il contributo propone una riflessione sulla distinzione tra attività del decidere e dell’agire delle organizzazioni, mettendo in luce la necessità di riconoscere le profonde differenze delle situazioni problematiche da cui emerge la scelta.
Metodologia. Il contributo muove dal ripercorrere alcune tappe fondamentali dell’evoluzione della teoria della decisione facendo emergere elementi di riflessione utili a comprendere la rilevanza della distinzione proposta.
Risultati. Il percorso interpretativo delineato conduce a far emergere la necessità di tener conto della differenza tra situazioni problematiche di decision making, tipiche della scelta in condizioni di complessità, e situazioni problematiche di problem solving, riconducibili a condizioni di complicazione.
Limiti della ricerca. Il contributo ha un essenziale carattere teorico e concettuale. Implicazioni pratiche. Notevoli sono le implicazioni manageriali della consapevolezza del dover decidere in condizioni di complessità, costatando l’inadeguatezza degli schemi risolutivi consolidati.
Originalità del lavoro. Il lavoro rappresenta un contributo alla riflessione sull’evoluzione dell’approccio alla decisione manageriale in condizioni di complessità
Bringing European University Alliances to High Schools: A Hands-On Collaborative Workshop
No full textEuropean University Alliances have emerged as a transformative initiative to foster collaboration, mobility, and innovation within higher education across Europe. Despite their growing relevance, younger audiences often demonstrate limited awareness and understanding of their significance. This paper presents a novel educational approach that utilizes Open Data to engage high school learners with alliance goals and evolution. The proposed activity involves an unplugged, hands-on, and collaborative experience in which participants analyze textual descriptions and validate information by cross-referencing them with data visualizations. Learners are assigned to distinguish between true and false statements based on materials presented in two distinct formats: scientific articles and dialogues resembling outputs from generative artificial intelligence systems. The study assesses the effectiveness of data-driven educational approaches in enhancing learners’ understanding and perceptions of European University Alliances, illustrating how Open Data can facilitate meaningful engagement with key concepts shaping the future of academia in Europe
Federated Learning under Attack: Game-Theoretic Mitigation of Data Poisoning
No full textFederated Learning (FL) is vulnerable to various attacks, including data poisoning and model poisoning, which can degrade the quality of the global model. Current solutions are based on cryptographic primitives or byzantine aggregation but suffer from performance and/or quality worsening and are even ineffective in case of data poisoning. This work proposes a game-theoretic solution to identify malicious weights and differentiate between benign and compromised updates. We use the Prisoner's Dilemma and Signaling Games to model interactions between local learners and the aggregator, allowing a precise evaluation of the legitimacy of shared weights. Upon detecting an attack, the system activates a rollback mechanism to restore the model to a safe state. The proposed approach enhances FL robustness by mitigating attack impacts while preserving the global model's generalization capabilities

Exploring deep eutectic solvents and enzyme-based hydrolysis for hemp seed flour valorization
No full textThis study explores the valorization of hemp seed cake flour (HSCF) through a combined delignification and
enzymatic hydrolysis approach aimed at improving its nutritional and technological properties for food applications.
HSCF was pretreated with a choline chloride–glycerol deep eutectic solvent (DES) under different
temperatures and biomass-to-solvent ratios. The optimal pretreatment conditions (120 ◦C, 1:8 biomass/DES)
achieved a 32.6 % reduction in lignin while maintaining high biomass recovery (>85 %). Subsequent enzymatic
hydrolysis reduced by 11,9 % the total insoluble fibre and led to the release of xylooligosaccharides (XOS) with
potential prebiotic activity. Structural analyses (FTIR, XRD) confirmed the selective disruption of the lignin–
hemicellulose–cellulose complex and improved crystallinity of cellulose. These results demonstrate that DESassisted
enzymatic hydrolysis provides an effective and sustainable route for upgrading hemp seed cake flour,
generating functional flours with improved compositional and structural attributes suitable for the development
of plant-based food products

«Turbando con il contagio dell'eresia la quiete dei popoli vicini»: Giovenale Vegezzi e il Memoriale storico-statistico intorno ai Valdesi (1829)
No full textIl seguente contributo si concentra sulla vita e sulle opere di Giovenale Vegezzi Ruscalla, in particolare sul Memoriale storico-statistico intorno ai Valdesi, redatto nell'anno 1829. Il documento, orientato a favorire la politica conservatrice di Carlo Felice, sottolinea strategicamente la magnanimità di Casa Savoia nei rapporti con il popolo valdese. Giovenale, corroborando la sua narrazione tramite il ricorso a fonti cattoliche, accusava le cronache protestanti di riportare dati storici e statistici spesso fuorvianti
