Infanzia e digitale. Le sfide di oggi, le scelte per domani
No full textL’infanzia contemporanea si sviluppa in un ambiente in cui il digitale è divenuto parte integrante della quotidianità, tra schermi, dispositivi connessi e piattaforme che attraversano casa, scuola e contesti di socialità. Il contributo propone di superare letture semplificate e posizioni polarizzate, riconoscendo la natura plurale delle esperienze mediali e l’importanza di distinguere dispositivi, contenuti, tempi e funzioni d’uso. Al centro viene posto il ruolo educativo degli adulti – genitori, insegnanti, educatrici – chiamati a mediare e accompagnare le esperienze digitali, integrandole con opportunità fisiche, ludiche, narrative e relazionali capaci di rispondere ai bisogni fondamentali dell’infanzia 0-6. Attraverso i concetti di mediazione, comunità educante e naturalizzazione del digitale, l’articolo delinea strategie per addomesticare gli schermi, orientando pratiche limitate, creative e situate, e promuovendo percorsi flessibili di sperimentazione condivisa. In tale prospettiva, il digitale non è né un destino né un tabù, ma una dimensione da integrare criticamente, anche in vista delle sfide poste dall’intelligenza artificiale alle pratiche educative future.Today’s childhood unfolds within an environment where digital technologies have become an integral part of everyday life, through screens, connected devices and platforms that permeate homes, schools and social spaces. This article invites readers to move beyond simplistic or polarized views, acknowledging the plural nature of children’s media experiences and the need to distinguish devices, contents, time and purposes of use. The focus is on the educational role of adults – parents, teachers, early childhood professionals – who are called to mediate and accompany children’s digital practices, integrating them with rich physical, playful, narrative and relational opportunities that respond to the core needs of 0–6-year-olds. Through the notions of mediation, educating community and naturalization of the digital, the article outlines strategies to tame screens by promoting limited, creative and context-based uses and shared, flexible experimentation paths. In this perspective, the digital world is neither a fate nor a taboo, but a dimension to be critically integrated into everyday life, also in view of the emerging challenges that artificial intelligence brings to educational practices
Decoding Living Lab sensing system through Bayesian networks: The preferable working space targeting comfort and productivity
No full textWorkplace environmental conditions significantly influence workers' well-being, health, and productivity. The understanding of the interaction between environmental factors across multiple domains can improve occupants' satisfaction and indoor conditions. This study aims to identify optimal office environmental conditions by analysing comfort demands and multi-domain interplay in a dynamic context. A year-long experimental campaign was performed in a Living Lab comprising five offices, monitoring indoor and outdoor environmental parameters and gathering occupants' feedback through surveys. Gaussian Naïve Bayes technique was applied to develop probabilistic models that identified optimal conditions for comfort and satisfaction, including self-perceived productivity as combined effect analysis. Participants showed more acceptability of warmer conditions in cooling seasons. Probabilistic models aligned with the current standards, indicating optimal temperatures of 22°C-24 °C for heating seasons and 23°C-24 °C for cooling seasons. Visual comfort was affected by the balance of natural and artificial light, with higher visual discomfort when the former was limited during cooling seasons. Temperatures higher than 22 °C demonstrated increased “stale air” discomfort, potentially linked to respiration and sweating, even without elevated CO2 levels. Self-perceived productivity decreased in temperatures higher than 24 °C and CO2 concentrations exceeding 800 ppm. Other factors and more comprehensive measurements, together with monitoring of physiological signals should be included in future studies, allowing the creation of guidelines for more comfortable office places. These findings offer valuable insights for enhancing workplace human-centric standards and regulations globally. They have the potential to shape policies that foster more sustainable productive environments for workers’ wellbeing worldwide
Use of high polymer-modified bitumen for compensating the presence of degraded SBS in the blends of aged and virgin polymer-modified bitumen: a laboratory study on the binder scale
No full textHot recycling of reclaimed asphalt pavement (RAP) in new hot mix asphalt (HMA) including polymer-modified bitumen (PmB) is problematic because the SBS in the RAP would be degraded or absent. To avoid this issue, the use of highly modified asphalt (HiMA) with an increased SBS content has been recently proposed. In the present study the rheological and performance behaviour of a blend including 50% of HiMA and 50% of RAP bitumen was evaluated in comparison with a reference virgin PmB and a blend including 50% of PmB and 50% of RAP bitumen treated with an ordinary recycling agent. The blend of HiMA and RAP bitumen showed an excellent performance in terms of resistance to permanent deformation and fatigue behaviour, as the excess of SBS in the HiMA entailed a noticeably marked elasticity of the bituminous blend. However, ageing caused a significant decrease of the performance for the HiMA + RAP blend
Malipiero simbolista. Modelli e ossessioni nel "Sogno d'un tramonto d'autunno"
No full textIl saggio esamina la drammaturgia e il retroterra estetico-compositivo del "Sogno d'un tramonto d'autunno", atto unico di Gian Francesco Malipiero su testo di Gabriele d'Annunzio, completato nell'autunno del 1913. Pur rimasta inedita e a lungo ineseguita, l'opera agì per il musicista veneziano come un catalizzatore di esperienze, e risulta imprescindibile per una piena compresione della sua poetica. Per la prima volta si offre una panoramica sui modelli 'rivissuti' da Malipiero: dalla "Fedra" di Pizzetti a "Elektra" di Strauss, con un'appendice sul "Sacre du printemps", che incrocia la trama decadente dell'eletta Pantèa, sacrificata nel fuoco del Bucintoro. Tutto ciò viene colto dall'interno della partitura malipieriana, che si credeva perduta ma giace nell'Archivio Ricordi di Milano. I nove esempi musicali che corredano il saggio sono intesi come una modalità di divulgazione di un'opera ignota tanto al pubblico quanto agli specialisti
INDUSTRIA 4.0
No full textL’intento è quello di raccogliere in un unico volume le “parole chiave” che ri-guardano, in modo particolare, l’ambito della Formazione Professionale e del lavoro, parole che contribuiscono a mettere a disposizione del pubblico una “grammatica comune”, necessaria oggi per districarsi in questo variegato sistema.
Per orientare il lettore, inoltre, i curatori dell’opera hanno progettato, avvalendosi dell’apporto del prof. Dario Nicoli, una guida alla lettura e alla consultazione del vo-lume attraverso il contributo “Le parole fondative della IeFP”.
Il progetto, con la scelta ragionata di raccogliere un campione consistente di voci (230 voci sviluppate, 461 se si calcolano anche i rimandi), offre “una panoramica” suf-ficientemente aggiornata sul sistema formativo e lavorativo italiano, inquadrato nel più ampio sistema di Istruzione e Formazione europeo e internazionale. Per meglio orientare il lettore nel volume è presente anche una “guida alla scelta” delle voci, organizzata per aree tematiche, una sorta di “bussola per orientarsi e per formarsi”
Kaldor–Kalecki Business Cycle Model: An 80-Year Multidisciplinary Retrospective
No full textBusiness cycles exhibit complex fluctuations driven by economic downturns and expansions. Understanding whether these fluctuations follow deterministic chaos is crucial for economic modeling and policy planning. This study investigates the presence of deterministic chaos in business cycles by analyzing real-world economic data and simulations based on the Kaldor–Kalecki model. Using advanced analytical techniques, including recurrence quantification analysis (RQA), principal component analysis (PCA), and wavelet entropy, we assess whether endogenous economic collapses can be simulated and detected in real data. The findings reveal that transitions from laminar (regular) to turbulent (chaotic) phases occur in both simulated and historical economic data, such as U.S. GDP downturns in 1949, 1953, and 1958. Moreover, statistical analyses confirm that the simulated and real-world data are indistinguishable, reinforcing the model’s validity. These insights suggest that different economies, despite following distinct developmental trajectories, may be governed by a shared deterministic dynamic. By identifying such structures in business cycles, this study contributes to improving economic forecasting and crisis detection methodologies, offering valuable implications for policymakers and economists
Investigating the relationship between spatial morphology, meteorological factors, and elderly people well-being in a traditional algerian village
No full textIn the face of climate change, outdoor spaces have become increasingly unfavorable due to heat conditions and the lack of adequate design strategies. The real consequences of these factors on human beings, both physiologically as well as physically and psychologically, are often overlooked in the short term that can turn into a long term with continuous exposure, particularly among elderly people. This study investigates the relationship between spatial morphology, meteorological factors, and the physiological and psychophysical responses of elderly people during a walk. The results demonstrated the elevation as a key factor influencing various physical environments and, consequently, elderly people's responses. High Sky View Factor (SVF) and low Height to Width ratio (H/W) significantly increased Skin Temperature of the Forehead (STForehead) and stress level, leading to a weakened state (P ≤ 0.001) and heightened thermal sensation (0.01 < P < 0.05), ultimately resulting in a decreased walking speed (P ≤ 0.001). In contrast, a higher Visible Green Index (VGI) and Building View Factor (BVF) under low mean radiant temperature (Tmrt) significantly reduced STForehead and stress level, leading to a relaxed and energetic state (P ≤ 0.001) while improving thermal perception (0.01 < P < 0.05). Thanks to the spatial configurations, including optimal H/W ratio, greenery, and northeast-southwest orientation, Tmrt was reduced approximately 5°C on one route compared to the other two. Additionally, the thermal sensation vote (TSV) could be predicted by the skin temperature of the forehead and the energetic-weak state. Meanwhile, the thermal pleasantness vote (TPV) could be predicted by STForehead, walking speed, and the relaxed-unrelaxed state
