Unravelling the rationalities of childhood cycling promotion
2022
Decrease of children’s independent mobility (CIM) has worried academics, policymakers, educators and other professionals for decades. Research and policy often emphasise that promoting children’s physically active and independent transport modes as cycling is important to achieve better public health, solve environmental challenges and increase related economic benefits. Yet, cycling promotion is not a neutral process and all promotion efforts are derived from latent notions of ‘cyclists’ and ‘cycling’. This paper discusses different rationalities of childhood cycling promotion and the representations of ‘children’ as independent ‘cyclists’ they entail. We argue that in order to efficiently…

The Perception of Not-for-Profit Organisations on Risks in Partnership with Czech, Sicilian and Castilian-Leonese Schools
2022
Non-proft sector and schools have different trajectories in the sphere of education and yet they both direct to the same goal – well-being of their target groups. What would happen if they joined their interests and transformed it into some kind of cooperation? Is it already happening and if so, how? This chapter focuses on the everyday reality of partnership between non-proft non-governmental organizations and schools, particularly in the area of inclusion of foreign language (FL) students in three European geographical areas – the Czech Republic, Castilla y León Autonomous Community of Spain, and Sicily in Italy. The three-year project aimed to map the extent of such cooperation and allow…
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. …
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…

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,…

Year-round variation in the isotopic niche of Scopoli's shearwater (Calonectris diomedea) breeding in contrasting sea regions of the Mediterranean Sea
2022
Top marine predators are key components of marine food webs. Among them, long-distance migratory seabirds, which travel across different marine ecosystems over the year, may experience important year-round changes in terms of oceanographic conditions and availability of trophic resources. We tested whether this was the case in the Scopoli’s shearwater (Calonectris diomedea), a trans-equatorial migrant and top predator, by sampling birds breeding in three environmentally different regions of the Mediterranean Sea. The analysis of positional data and stable isotopes (δ13 C and δ15N) of target feathers revealed that birds from the three regions were spatially segregated during the breeding per…

Nel presente contributo l’esercizio delle abilità di leggere e comporre testi è stato indagato su un gruppo di studenti …
Toponymic politics and the role of heritagisation in multiethnic cities in Romania
2022
Although scholars have made considerable progress in understanding the dynamics of heritagisation and toponymic politics, research is yet to explore how these may interact with each other. Drawing on a mixed-methods comparative qualitative study, this paper explores the politics of place naming and multilingualism in the context of heritagisation in three multiethnic cities in Romania: Târgu Mureş, Oradea and Baia Mare. We argue that the recent trends of heritagisation introduce a new element in the politics of place naming in ethnically diverse cities. Heritage becomes inclusive when it loses its importance in the power struggle between minority and majority political representatives. Once…
Association between physical multimorbidity and sleep problems in 46 low- and middle-income countries
2022
BACKGROUND: Little is known about the association between multimorbidity (i.e., two or more chronic conditions) and sleep problems in the general adult populations of low- and middle-income countries (LMICs). Thus, we aimed to assess this association among adults from 46 LMICs, and to quantify the extent to which anxiety, depression, stress, and pain explain this association. METHODS: Cross-sectional, predominantly nationally representative, community-based data from the World Health Survey were analyzed. Nine chronic physical conditions (angina, arthritis, asthma, chronic back pain, diabetes, edentulism, hearing problems, tuberculosis, visual impairment) were assessed. To be included in th…
Digital Education For All: Multi-University Study of Increasing Competent Student Admissions at Scale
2022
An indubitable way to put learning at scale in practice is to implement Massive Open Online Courses, or MOOCs. When a wide-enough portfolio of them is available, new applications arise. For instance, university admissions in Finland, where this study was conducted, have traditionally been based on students' grades in high school studies, an entrance examination, or a combination of both. A minority of students have been accepted through an open university admission path where students can get a study right if they complete enough university course credits with a high enough grade in a given time frame. In this work, we report results from a multi-university project in which the open univers…
Studio della qualità dei frutti e della risposta fotosintetica di tre cultivar di Mango (Mangifera indica L.) coltivate in serra in Sicilia
2022
La coltivazione del mango all’interno di una serra in Sicilia sottopone le piante a temperature estremamente elevate, fino a 50 °C, mentre le temperature minime registrate in serra durante la notte nel corso dell’anno non differiscono da quelle registrate all’aperto. Nonostante le alte temperature estive, l’attività fotosintetica delle piante ha mostrato valori elevati (fino a 20μmol (CO2)/s), ovvero uno dei più alti per il mango sulla base di quanto finora riportato in letteratura. I frutti ottenuti erano di alta qualità, non presentavano imperfezioni derivanti da danni di natura biotica o abiotica. Avevano, inoltre, un elevato contenuto zuccherino e sono stati pienamente apprezzati dai gi…
Análisis del aumento de seguidores y de la presencia multiplataforma de la clase política en Facebook, Twitter e Instagram en campañas electorales (2…
2022
[EN] The participation of politicians in social media is increasingly necessary in order to gain visibility. However, the logic of content dissemination is very different from conventional media. In social media, building a broad and varied base of followers facilitates a greater impact of the message. This article analyses the influence of various individual factors of the candidates on two aspects of the process: variation in the number of followers and multiplatform presence. Both issues are assessed on Facebook, Twitter, and Instagram in the context of three general elections held in Spain during the 2010s. The results show that the age and gender of the candidates, their frequency of p…
Sindacato di legittimità costituzionale e legalità penale: il delicato equilibrio tra ruolo della Corte Costituzionale e discrezionalità del legislat…
2022
The paper intends to focus on the issue of the relationship between the judgment of constitutional legitimacy and the legislator's discretionary power in criminal matters. The Constitutional Court, especially in recent years, has carried out an overall rewriting of criminal law, through rulings that have affected some of the most significant institutions, introducing a substitute regulation for that deliberated by the legislator. To achieve this result, in the name of safeguarding fundamental rights, the Constitutional Court devised new techniques of adjudication, forcing patterns that had already been established in its jurisprudence or proposing new ways of adjudication in incidental proc…
Una forma leggiadra. Simboli sessuali dell'altalena in India nel rito del mahavrata e in alcune pratiche contemporanee
2022
In the grammar of rituals described in Vedic texts, the swing was an object whose meanings referred to the propitiation of fertility and solar symbolism. Although its use remains in various contemporary festive contexts, its meaning has been differently defined. By analyzing the passages from works belonging to the ancient religious literature, this article examines the description of the swing’s construction and the rite performed on it by the officiant named hotr. Such an approach allows us to focus on the symbolic elements related to the swing in one of the focal points of the sequence of the mahavrata ceremony. Through a diachronic investigation and considering the data from the compara…
The circular economy for resilience of the agricultural landscape and promotion of the sustainable agriculture and food systems
2022
The agricultural landscape is a public good to be preserved for long-term socio-economic and environmental effects. The agricultural landscape is preserved by the carrying out of agricultural activities. Through a empirical survey we examined how some young farmers in the countryside adopt conservation and resilience strategies. A common feature of the case studies examined is the adoption of photovoltaic energy production necessary for the performance of business activities. The method applied is that of the opportunity cost. The results of the research show that young farmers after graduation have returned to agriculture as they have an advantage in terms of opportunity costs compared to …

Machine learning for ultrafast nonlinear photonics
2022
Recent years have seen the rapid growth of the field of smart photonics where the deployment of machine-learning strategies is the key to enhance the performance and expand the functionality of optical systems. Here, we review our recent results obtained in collaboration with the University of Aston (S. Boscolo) and the University of Franche-Comté (J.M. Dudley) by providing several examples of advances enabled by machine-learning tools such as neural networks (NNs).We describe the use of a supervised feedforward NN paradigm to solve the direct and inverse problems relating to nonlinear pulse shaping in optical fibres, bypassing the need for direct numerical solution of the governing propaga…
La poltrona di Proust. Evoluzione ed epistemologia di una relazione di prossimità tra design e artigianato.
2022
The proximity between craft and design has been identified as one of the many reasons for the success of what has been the Made in Italy phenomenon, and now the contemporary design scenario shows a strong tendency to contamination of skills from one discipline to the other. This paper offers a critical analysis of the evolution of this relationship to identify new cognitive tools to interpret and categorise the instances of hybrid design in the era of design when everybody designs.
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. …
Biological Monitoring Using Lichens as a Source of Information About Contamination of Mountain with Heavy Metals
2022
Abstract The aim of this study was passive biomonitoring of the mountains of southern Poland. Lichens Hypogymnia physodes were used for the study. Concentrations of the heavy metals Ni, Cu, Zn, Cd and Pb were determined in these lichens. The concentrations were measured by atomic absorption spectrometry (AAS). The analysis of the concentrations of the determined heavy metals in the lichen thallus allowed to determine the places with the highest and the lowest contamination with a given heavy metal in the study area. It was shown that the area of Great Czantoria and Big Soszow is the most contaminated with heavy metals among the investigated areas. The study shows that the transport of analy…
Città post-pandemiche tra ricerca della giustizia spaziale e nuove forme di disuguaglianza
2022
Le necessarie misure adottate dal Governo italiano per fronteggiare la pandemia, soprattutto nella prima fase di lockdown, con la chiusura delle attività produttive, commerciali e culturali, hanno amplificato le contraddizioni già presenti nelle città e nei territori del nostro Paese evidenziandone le fragilità. L’acuirsi di nuove forme di disuguaglianza si sta riverberando sullo status di sofferenza socio-economica in cui già si trovavano le fasce più vulnerabili della popolazione in condizione di marginalità o a rischio di povertà. Tale circostanza conferma come i luoghi in cui viviamo costituiscano, in termini di giustizia spaziale, la prova delle concrete disparità sotto il profilo dell…
Management of severe asthma during the first lockdown phase of SARS-CoV-2 pandemic: Tips for facing the second wave.
2022
SARS-CoV-2 pandemic has contributed to implement telemedicine, allowing clinicians to follow the patient remotely, therefore minimizing the risk of any exposure to positive COVID-19 patients. We summarize the approaches adopted to treat and monitor severe asthmatic patients during the lockdown phase of the pandemic. Our experience supports the strategy that every effort should be made to minimize patient contact with the health-care system, planning a pathway that allows patients to receive appropriate medical care and continue the biological therapies, thus preventing the loss of disease control and acute severe exacerbations.

2022
The quality of wintering habitats, such as depth of snow cover, plays a key role in sustaining population dynamics of Arctic lemmings. However, few studies so far investigated habitat use during the Arctic winter. Here, we used a unique long-term time series to test whether lemmings are associated with topographical and vegetational habitat features for their wintering sites. We examined yearly numbers and distribution of 22 769 winter nests of the collared lemming Dicrostonyx groenlandicus (Traill, 1823) from an ongoing long-term research on Traill Island, Northeast Greenland, collected between 1989 and 2019, and correlated this information with data on dominant vegetation types, elevatio…
IL RAPPORTO DI LAVORO INDECENTE E LA VULNERABILITà SOCIALE
2022
Una riflessione più attenta sul tema dello sfruttamento del lavoro e, più nello specifico, sulle pratiche contrarie al lavoro dignitoso, oggi è suggerita dal contesto economico e sociale e dalla precarizzazione dell’occupazione, il cui effetto è quello di produrre una corrente svalutazione del lavoratore.
Making Space for Creativity : Niche Construction and the Artist’s Studio
2022
Abstract It is increasingly acknowledged that creativity cannot be fully understood without considering the setting where it takes place. Building on this premise, we use the concepts of niche construction, scaffolding, coupling, and functional integration to expound on the environmentally situated nature of painters’ studio work. Our analysis shows studios to be multi-resource niches that are customized by artists to support various capacities, states, and actions crucial to painting. When at work in these personalized spaces, painters do not need to rely solely on their “inner” powers of imagination, memory, decision making, and technique to execute their paintings. Instead, with the help…
Coping with pandemics using social network sites: A psychological detachment perspective to COVID-19 stressors
2022
Prior research has often portrayed information technology (IT) as a stressor. In this paper, we propose and demonstrate that IT can also be an effective means of coping with life stressors, including those induced by pandemics such as COVID-19. We thus deviate from the common IT-as-a-stressor perspective and adopt an IT-as-a-coping-mechanism viewpoint. To this end, we apply the stressor-detachment model from organisational psychology to the use of social network sites (SNSs) in coping with stressors wrought by the COVID-19 pandemic. We examine psychological well-being as our dependant variable and introduce psychological detachment through SNS use as a mediator and moderator of the associat…
Management of pharyngeal collapse in patients affected by moderate obstructive sleep apnoea syndrome
2022
This study reports our experience in a selected cohort of patients affected by mild-moderate OSAS, without tonsillar obstruction, and treated with pharyngoplasty.In a case-control retrospective study, we compared modified expansion sphincter pharyngoplasty (MESP) to modified barbed reposition pharyngoplasty (MBRP) in adult patients with oropharyngeal transversal collapse with a BMI ≤ 30 kg/mWe enrolled 20 patients: 10 treated with MESP and 10 treated with MBRP. Mean apnoea-hypoapnoea index (AHI) was 22.8 (± 5.63). We observed in both groups a significant reduction of AHI and oropharyngeal obstruction (p = 0.01), with a success rate, according with Sher's criteria, of 90% for MESP and 80% fo…

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…
La determinazione del Fondo crediti di dubbia esigibilità nel rendiconto della gestione
2022
La determinazione dell’accantonamento al Fondo crediti di dubbia esigibilità in sede di rendiconto non appare di univoca interpretazione, con specifico riferimento alla definizione del quinquennio per il computo delle medie. Esemplificazioni numeriche chiariscono la differente entità dell’accantonamento discendente dalla diversa scelta del quinquennio. Attraverso l’analisi della giurisprudenza contabile e di differenti orientamenti di associazioni di categoria, il lavoro mira a chiarire quale sia, a parere di chi scrive, il più corretto - e anche logico - percorso da seguire, auspicando comunque una revisione del principio contabile applicato della contabilità finanziaria, allegato n. 4/2 a…

The brighter side of materialism : Managing impressions on social media for higher social capital
2022
Individuals adjust their behavior on social media to varying extent, and commonly in their idealized way. Most studies have focused on the problems associated with materialism and social media use, yet their potential positive contributions remain less clear. In fact, impression management holds potential for both negative and positive: it has been linked with materialistic attitudes, but also increased amounts of self-reported social capital. This study examines how young people's materialistic values connect with status-seeking impression management on social media, and subsequently to social capital, within the same model. Eight hundred Finnish participants aged 15–19 participated in our…
