Central polynomials of graded algebras: Capturing their exponential growth
2022
Let G be a finite abelian group and let A be an associative G-graded algebra over a field of characteristic zero. A central G-polynomial is a polynomial of the free associative G-graded algebra that takes central values for all graded substitutions of homogeneous elements of A. We prove the existence and the integrability of two limits called the central G-exponent and the proper central G-exponent that give a quantitative measure of the growth of the central G-polynomials and the proper central G-polynomials, respectively. Moreover, we compare them with the G-exponent of the algebra.

Imagine there’s no borders. Miti identitari, percorsi di viaggio, sguardi sull’altro dall’Antichità al Medioevo
2022
Sulla dicotomia identità e alterità la critica moderna si è molto esercitata negli ultimi decenni, mettendo a punto un armamentario di strumenti e categorie analitiche utili a identificarne i rispettivi spazi di applicazione: da un lato, troviamo dunque l’identità, con tutto il suo repertorio di parole-chiave, quali tradizione, memoria, scrittura, purezza, coerenza; dall’altro, l’alterità, in tutti i suoi gradi, che vanno da una potenziale assimilabilità a un’estraneità radicale, espressa, volta per volta, dalla climax di termini quali ospite, straniero, rifugiato politico, esiliato, nemico, invasore. Il volume che qui presentiamo si propone di indagare, attraverso una galleria di casi stud…

Does happiness drive tourism decisions?
2022
This research examines the role that happiness plays in affecting tourism flows. While most previous studies are country-specific, our analysis is performed with panel data on 142 countries from 2005 to 2019. This allows us to implement a structural gravity model that includes both domestic and international tourism flows, which is a novel approach in this branch of the literature. Our empirical strategy enables us to correctly identify happiness when multilateral resistance terms are included. The results show that happiness at a destination is a significant tourist attractor, although the link follows an inverted U-shaped pattern. This suggests that tourists associate happiness with the q…
Lionello Perera: An Italian Banker and Patron in New York
2022
The book presents the long-lost biography of Lionello Perera, principal banker, patron, and philanthropist of the Italian American community in New York at the inception of the twentieth century. Born and raised in Venice, Lionello Perera took over his uncle’s financial activity in Wall Street and developed the family business into a stronghold of the Italian American community. His remarkable career led him to become the Vice President of Bank of America in 1928 as an associate of California born Amadeo P. Giannini, while he also was instrumental to the political success of New York mayor Fiorello La Guardia. Recognised as a true founding father of the Italian American community of the Eas…
Diritto d’asilo. Accessibilità e riciclo dell’ex Asilo Biondo a Danisinni, Palermo

There are many virtuous initiatives, national and international, which, starting from school buildings, have aimed at redeveloping some degraded urban spaces through paths aimed at increasing civic sense and social and environmental sensitivity in pupils, parents and citizens. . Reopening schools in neighborhoods characterized by a high school dropout was the goal of the research aimed at making accessible the paths and spaces in school buildings and starting urban and architectural recycling projects in waiting places. The research thus proposed field work in opposition to an ongoing process carried out by the municipal administration of Palermo which identified precisely in obsolete or ab…
Il Problem Based Learnig (PBL) come strumento di orientamento nella scuola secondaria di primo grado
2022
La scuola costituisce indubbiamente un luogo privilegiato di inserimento sociale, di partecipazione e di confronto e allo stesso tempo per imparare ad orientarsi e in cui gli alunni vengono incoraggiati attivamente al ragionamento e alla risoluzione dei problemi ricavando e attingendo in modo autonomo a tutte le fonti informative necessarie a tale scopo. L’ipotesi di ricerca da cui lo studio parte è che la metodologia didattica dell’apprendimento per problemi (PBL) sia efficace nello sviluppo di competenze strategiche (problem-solving, decision-making) e, pertanto, possa essere applicata nelle attività di orientamento. L’attività di Problem-Based Learning è stata proposta a 98 docenti di s…

Con una pervasività ed una velocità inusitate, la disintermediazione ha impresso il suo sigillo sulla nostra era. È il principio su cui si fonda tutta la tecnologia dell’universo blockchain che, sostituendo tutte le istituzioni centrali con reti orizzontali, aperte e condivise di blocchi, valida le operazioni senza bisogno di controllori, notai o terze parti (di qui anche il discusso fenomeno dell’NFT, “non-fungible token”, permette di comprare un’opera senza il bisogno di una galleria/ un mediatore). Una svolta di enorme impatto che, dalla verticalità centralizzata con cui veniva dispensata la cultura dei corpi intermedi, giunge all’orizzontalità decentralizzata che connette gli individui,…

Early-stage thermal performance design of thermo-active walls implemented in underground infrastructures
2022
Abstract Energy geostructures (EGs) represent an innovative technology in the sustainable energy agenda and are useful for satisfying the energy needs of the built environment. They are usually involving geostructures such as piles, walls, tunnels, shafts, and sewers. The application of such technology to infrastructure projects may have considerable thermal potential because of the large surfaces that can be thermally activated. This study focuses on thermo-active walls (energy walls, EWs), which are retaining structures used to sustain the sides of excavations. Key features related to their thermal design are examined, and a design methodology is proposed. The heat-exchange modes involvin…

Le Officine Ducrot, un esempio di organizzazione del lavoro dell'industria palermitana tra il XIX e il XX secolo
2022
Le officine Ducrot sono un'importante testimonianza del fiorente passato imprenditoriale palermitano che ha avuto un ruolo centrale tra la fine dell'Ottocento e i primi del Novecento del secolo scorso per il carattere internazionale e innovativo di una attività, nata da un piccolo mobilificio, trasformata in pochi anni in un prestigioso atelier artigianale, fino a diventare una società di produzione industriale con una affermazione artistica e commerciale tale da ottenere la quotazione in Borsa. I motivi del grande successo sono numerosi: il sodalizio tra il proprietario, Vittorio Ducrot, e l'architetto Ernesto Basile; la produzione di raffinati e moderni arredi, caratterizzati da un mix tr…

Scale-dependent patterns and drivers of vascular plant, bryophyte and lichen diversity in dry grasslands of the Swiss inneralpine valleys
2022
AbstractThe inner-alpine dry valleys of the Swiss Alps are characterized by subcontinental climate, leading to many peculiarities in dry grassland species composition. Despite their well-known uniqueness, comprehensive studies on biodiversity patterns of the dry grasslands in these valleys were still missing. To close this gap, we sampled 161 10-m2 vegetation plots in the Rhône, Rhine and Inn valleys, recording vascular plants, terricolous bryophyte and lichen species, as well as environmental data. Additionally, we tested the scale-dependence of environmental drivers using 34 nested-plot series with seven grain sizes (0.0001–100 m2). We analysed the effects of environmental drivers related…
Sull'eterogeneità del Mezzogiorno
2022
Il capitolo rappresenta l'ambizioso tentativo di costruire un modello di sviluppo locale in grado di spiegare il "mistero della crescita" e fornire elementi di guida e di riflessione per le diverse componenti coinvolte a realizzare il cambiamento. Un aspetto viene messo in particolare luce: l'analisi quali-quantitativa sulle determinanti della profonda eterogeneità dei Sud, anche di quelli che sono geograficamente, storicamente, tradizionalmente contigui e da lungo tempo radicati in una condizione di relativa e trasversale arretratezza o apparente immobilismo. Questa eterogeneità emerge chiaramente man mano che l'attenzione si sposta ai diversi ambiti di sviluppo locale.
OPTIMAL OPERATION OF POWER-SPLIT HYBRID ELECTRIC POWERTRAIN: COMPARISON BETWEEN TWO PERFORMANCE INDICES
2022
Among all the current environmentally-friendly ground vehicles proposed to reduce fuel consumption and emissions, power-split hybrid electric vehicles represent one of the most promising solutions. Their operation is based on the cooperation of the thermal engine and the electric unit enabled by mechanical transmissions consisting of planetary and ordinary gear sets. However, implementing proper energy management strategies to realise the best powertrain operations is crucial to maximise the environmental gain without compromising performance and drivability. For this purpose, an initial comprehensive analysis of the powertrain response is required. In this respect, this paper relies on a u…
BIODEGRADING BIOFILMS ON INNOVATIVE BIOPOLYMERIC SUPPORTS
2022
ABSTRACT Water bioremediation is traditionally carried out using ‘ free ’ bacterial cells, however, in recent years, utilization of ‘immobilized’ bacterial cells on adsorbing matrices, has gained attention as a promising technique due to biotechnological and economic benefits (Sonawane et al., 2022). Bacterial biofilms show greater resilience, survival and degradative activity for longer periods than cells in the planktonic state (Alessandrello et al., 2017); moreover immobilization reduces bioremediation costs, eliminate cell dilution and dispersion in the environment (Bayat et al., 2015). Possible applications of immobilized biodegrading bacteria require long-term survival and maintenance…
Farming on the margins : Just transition and the resilience of peripheral farms
2022
Sustainability transition demands fundamental changes taking place at the farm system level. At the same time, many farms are operating on the verge of financial profitability, especially in geographically disadvantaged peripheral regions with a limited range of production opportunities. These observations raise concerns about the transition's justice aspects. Using the concept of resilience, we analysed farmers’ capacities for transformation in a peripheral context in Finland. The results from our farmer survey (n = 577) indicated that the regime exerts a strong cost-price squeeze on farmers, escaping of which is difficult also for farmers deliberately seeking new pathways beyond it. Due t…

Life cycle environmental assessment of retaining walls in unsaturated soils
2022
Abstract Retaining structures above groundwater level support soils that are usually in a state of partial saturation and subject to the actions of atmospheric agents. The current design approach considers the possible extremes of soil conditions – either totally dry or totally saturated – but it neglects matric suction’s contribution to soil shear strength. This work aims to describe how unsaturated-soil mechanics of can positively influence the sustainability of retaining structures through a holistic, multidisciplinary, geotechnical, and environmental analysis. The geotechnical analysis allows to estimate the lateral earth pressure of a geostructure in both unsaturated and extreme soil c…
When more is less: The other side of artificial intelligence recommendation
2022
Based on consumers' preferences, AI (artificial intelligence) recommendation automatically filters information, which provokes scholars' debate. Supporters believe that by analyzing the consumers' preferences, AI recommendation enables consumers to choose products more quickly and with lower cost. Critics deem that consumers are more easily trapped in information cocoons because of the use of AI recommendation. This reduces the possibility of consumers contacting with a variety of commodities, thus lowering the consumer decision quality. Based on experiments, this paper discusses the moderating role of AI recommendation on the relationship of consumers' preferences and information cocoons. …

Lo sviluppo economico è/e lo sviluppo della qualità: un parco dell'innovazione a Catania
2022
Il tema delle periferie produttive (o ex produttive) negli ultimi anni ha assunto un ruolo predominante nella pianificazione delle città al fine di rivalutare le aree industriali dismesse come serbatoi per la riqualificazione urbana ed economica delle nostre città. Sicurezza, degrado sociale e ambientale, abbandono, consumo di suolo sono le principali problematiche di queste aree e investire nella loro riqualificazione può essere un’occasione centrale per la “ripartenza” economica delle nostre città. Per tale motivo, la Regione Siciliana ha recentemente designato una vasta area della città di Catania come “Zona Economica Speciale” (ZES) per il rilancio delle filiere economiche della città. …
Biostratigraphy of the Ribota and Huérmeda formations (Cambrian Series 2) in the Comarca del Aranda (Zaragoza province), Iberian Chains (NE Spain)
2022
This article presents a detailed biostratigraphic analysis of the Cambrian Series 2 Ribota and Huérmeda formations of four sections of the Iberian Chains (NE Spain), and a systematic study of their trilobite faunas. We identified four major assemblages: two in the middle part of the Ribota Formation, one at the base of the Huérmeda Formation and one at the top of the Huérmeda Formation. The studied species permit the assignment of these formations to the middle and upper Marianian and probably lower Bilbilian stages in the regional stratigraphic chart for the Iberian Peninsula, which correlates with an interval around the Cambrian Stage 3–4 boundary. The assemblages exhibit a great correlat…
