Let’s Pay by Card! Determinants of Visitor Expenditure During the Venice International Film Festival Within a Spatial Panel-Data Framework
No full textThe relationship between tourism and events has been widely studied, with a focus on visitor motivations, behaviors, and the socioeconomic impacts of hosting events. However, research on visitor expenditure during events remains limited and often relies on survey-based approaches, typically centered on willingness to pay. The present study adopts an approach for aggregated big data, primarily using Mastercard credit card transaction and Vodafone mobility data, to analyze actual visitor expenditure. Focusing on the Venice International Film Festival, a prestigious cultural event held in one of Europe’s most visited destinations, this research applies a spatiotemporal econometric model to examine the expenditure patterns of four visitor clusters: domestic, cross-border, consumer, and commercial cardholders. The findings reveal the diverse economic impacts that a cultural event can generate, highlighting variations in expenditures across visitor types and locations in Venice during the event period

Multimodal Intention Recognition for Dynamic Tool Sharing in Anthropocentric Human-Robot Collaborative Applications
No full textIn the context of Industry 5.0, designing anthropocentric human-robot collaborative applications is essential. Moreover, the ability to share production resources, such as tools, in a safe, ergonomic, and efficient manner is a prerequisite for implementing seamless human-robot collaboration. This work aims to develop a tracking system capable of combining the motion and gaze of an operator to infer his/her intentions during a collaborative task involving a shared tool within a manufacturing context. Wearable inertial sensors, combined with a kinematic model of the human, were used to track the operator’s actions, while eye-tracking glasses were employed to determine his/her gaze point relative to the shared tool. A neural network was trained exploiting wearable sensor data to predict the operator’s intention to perform a task. A practical case study was designed, and the developed tracking system was validated through multiple tests assessing reaction time, stopping distance, and reliability. The results indicate that adopting a multimodal signal approach that combines both tracking solutions significantly improves the system’s performance in inferring the operator’s intentions. Thanks to the combination of the eye-tracking and the motion-tracking system, a progressive reduction in reaction time was observed, i.e. from 2.05 to 1.62 s. Additionally, the failure rate for incorrectly recognizing human actions dropped from 37.5% to 7.5%. Overall, the tracking system correctly recognized the operator’s movements 95% of the time. These improvements enhance safety and ergonomics in collaborative environments, particularly in scenarios involving shared production tools
Leonardo Bruni’s Translation of the Speeches in Iliad 9
No full textAt the end of the thirties of the fifteenth century, Leonardo Bruni from Arezzo (1370-1444) translated into Latin prose three passages of the ninth book of the Iliad, that is, the verses containing Ulysses’ speech (222–305), Achilles’ reply (310–425), and Phoenix’ speech (435–605). He entitled this translation Orationes Homeri and explained in a preface (Prohemium) that the three speeches are supposed to be a model of perfection respectively in the three genres of oratory: “subtle,” “stately,” and “middle.” Exemplary of the humanistic translation method, the Orationes is based on precise aesthetic requirements and uses a typically Ciceronian language and style. It is therefore a work noticeably different from the previous Homeric translation of Leontius Pilatus. In the course of the fifteenth century, Bruni’s Orationes became an essential point of reference for other humanists who undertook the translation of Homeric poems (among them Pier Candido Decembrio and Lorenzo Valla)

Attitudes Toward Forest-Based Health and Wellness Practices: Evidence from an Exploratory Study in Northern Italy
No full textThis study examines the motivations, socio-demographic profiles, and behavioural orientations
of residents in Northern Italy toward mountain and forest visitation, with a focus
on their propensity to engage in forest-based health and wellness activities. The analysis
draws on a large stratified survey conducted between December 2023 and January 2024,
involving 1218 respondents, of whom 976 reported regular forest visitations. Exploratory
factor analysis identifies two main attitudinal dimensions: “Health andWellness-Driven
Forest Engagement”, centred on psychophysical restoration, and “Comfort-Oriented Forest
Use”, related to accessibility and low physical effort. Regression models show that wellnessoriented
engagement is strongly associated with psychological well-being, walking and
hiking habits, and gender, while comfort-oriented use reflects seasonal patterns and preferences
for easily accessible forests. A small subset of respondents reports discomfort in forest
environments, forming a distinct attitudinal barrier. Overall, the results indicate substantial
potential for forest-based wellness tourism to support healthier lifestyles and diversify
mountain economies. Policy implications highlight the need for accessible infrastructures,
targeted communication, and the integration of wellness-oriented services into regional
development strategies
La frode informatica (art. 640-ter)
No full textIl contributo analizza il delitto di frode informatica (art. 640-ter c.p.) nel contesto della criminalità digitale, evidenziando come la vulnerabilità delle vittime derivi prevalentemente dalla struttura stessa dell’ambiente informatico. La cooperazione della persona offesa, spesso inconsapevole, si colloca soprattutto nelle fasi prodromiche della captazione dei dati (phishing, smishing, malware), mentre la lesione patrimoniale si realizza tramite un’aggressione unilaterale al sistema. Muovendo dalla genesi normativa della fattispecie, si sottolinea il superamento degli schemi della truffa tradizionale, in assenza di induzione in errore e atto dispositivo, e la maggiore affinità dell'art. 640-ter con la fattispecie di furto. Vengono esaminate le nozioni di sistema informatico e telematico, le modalità della condotta incriminata (alterazione o intervento abusivo) e il dibattito sull’abusività dell’accesso. Centrale è la ricostruzione del danno e del profitto in chiave patrimoniale, nonché l’analisi delle circostanze aggravanti, con particolare attenzione al furto o indebito utilizzo dell’identità digitale
Microalgae‐Mediated Heavy Metal Removal From Wastewater: A Review on Recent Perspectives and Future Trends
No full textHuman activities such as the development of industries, mining, disposal of heavy metal and electronic wastes, use of coal, leaded gasoline, pesticides, and various fertilizers cause contamination of water resources with heavy metals such as Zn, Hg, Cd, Pb, and Cr. Exposure to heavy metals can cause acute poisoning, cancer, damage to the kidneys, liver, and lungs, and even death. Recent innovations introduce modern and environmentally friendly techniques to remediate heavy metal contamination in wastewater. Meanwhile, the biological processes using algal species are gaining importance for sustainability, simplicity, and environmental benefits. Phytoremediation, as this method is known, involves intracellular and extracellular mechanisms, including cell surface biosorption, intracellular accumulation, and interaction with antioxidant enzymes. Such mechanisms change the pollutants by reducing their toxicity and reactivity, ultimately leading to their detoxification or transformation into less harmful compounds. The type of microalgae, the concentration and type of heavy metals, and the physicochemical conditions of the environment are factors that affect the efficiency of this process. In addition, the toxic effects of these elements on the environment and living organisms and their removal/detoxification mechanisms by microalgae and finally the challenges and perspectives of this method were investigated. The commercial application of microalgae still demands attention because of extended retention times compared to other methods, which leads to the need for larger areas. Thus, further improvement of this technique for optimal results is still needed and necessitates detailed analysis
A cohesive phase-field method for seamlessly modelling intergranular and transgranular fracture in polycrystalline materials
No full textDue to their microstructural inhomogeneity, predicting damage and fracture mechanisms in polycrystalline materials at the micron scale remains challenging. Therefore, accounting for microstructural features involved in damaging processes is of paramount importance in addressing this critical problem. This study proposes a novel cohesive phase-field approach to seamlessly simulate intergranular and transgranular failure within a realistic polycrystalline microstructure, capable of accounting for grain boundary cohesive properties. It relies on complete control of local material properties within the considered solid domain while exploiting the flexibility of the cohesive phase-field formulation. To exploit the model’s capabilities, an image segmentation technique was developed, enabling realistic microstructure modelling. This technique serves as input for Finite Element-based simulations in an open-source FEniCS library integrated into GPFniCS, a code previously proposed by the authors. Two case studies demonstrate the model’s capabilities: a one-dimensional problem with a cohesive interface and a two-dimensional cantilever bending scenario in polycrystalline material. The proposed approach is also validated with the commercial cohesive zone method (CZM). The proposed model opens new avenues for designing and optimising polycrystalline materials with unprecedented fracture toughness, while also revealing the failure mechanisms at this critical scale in currently available materials
