Stones, maps and cities
2021
Il presente contributo, articolato in tre paragrafi, propone una riflessione sulla prospettiva che, all'interno dell'approccio geografico, sottolinea il valore della rappresentazione cartografica. Dopo aver sintetizzato brevemente il contesto teorico attraverso una serie di spunti ed episodi, si propone una riflessione sugli spazi urbani contemporanei, che intreccia i discorsi geografico, urbano e letterario, sulla necessità inalienabile di risolvere la complessità nel segno cartografico. La mappa, intesa come modello di conoscenza, accompagna da sempre l'uomo nella rappresentazione dei luoghi ma, soprattutto, nella rappresentazione del sé nello spazio. Può la città contemporanea, apparente…
Agro-hydrological models and field measurements to assess the water status of a citrus orchard irrigated with micro-sprinkler and subsurface drip sys…
2021
Compared to the micro-sprinkler irrigation, traditionally used in citrus orchards, subsurface drip systems (SDS) allow increasing the water use efficiency (WUE); when coupled with water-saving strategies, like regulated deficit irrigation (RDI), further increase of WUE are possible. Combining measurements of soil water content (SWC) and weather data with measurements of midday stem water potential (MSWP) makes it possible to identify irrigation scheduling parameters for the RDI. However, measurements of MSWP are destructive and time-consuming, and also require skilled operators. For all these reasons, the use of the agro-hydrological models, such as the FAO-56 model, can be considered a sur…
Transforming student contributions into subject-specific expression
2021
Drawing on a corpus of pre-service teacher training classroom interactions in an English-medium instruction university in Turkey, we examine teacher follow-up turns that introduce specialized terms, showing how a teacher transforms student’s responses into pedagogically relevant points using academic language. We argue that teacher third-turns following student contributions accomplish several interrelated actions, not only introducing new terminology to these teachers-in-training, but also familiarizing them with ways of thinking specific to their discipline, i.e., these turns model “doing being a teacher.” These teacher actions are used to bridge student contributions to more scientific t…

INSEGNARE AL MASCHILE E AL FEMMINILE SECONDO GIUSEPPE MARI
2021
La riflessione storica e quella teoretica di Mari sul dimorfismo sessuale, che è presente in tutte le culture, costituiscono la base per giustificare la differenziazione parziale dell’educazione del ragazzo e della ragazza, considerando i ruoli che essi svolgeranno, l’uno di padre e l’altra di madre: una paternità e una maternità che vanno ben oltre la generatività fisica. Mari ha collocato la didattica di genere all’interno del sistema pedagogico dell’educazione personalizzata. The historical and Mari's theoretical reflection on sexual dimorphism that exists in all cultures form the basis for justifying the partial differentiation in boy and girl education, considering the roles they will …

Identità russe in transito nella New York di Ljudmila Ulickaja
2021
The essay analyses the atypical concept of border in the povest' by Ljudmila Ulickaja 'Veselye pochorony' (1997). This short novel offers several images related to the symbolic setting represented mainly by the city of New York, which embodies an idealized 'border city', where some Russians immigrants arrive and meet in 1991. First of all my research aims to to examine the role played by a few peculiar places represented in 'Veselye pochorony', in order to highlight the emotional dynamics of some Ulickaja's characters, who have to face the difficulties of integration in a cultural and social environment, totally different from the one they come from. Moreover this essay investigates the dev…
Redox-related biomarkers in physical exercise

Running to keep up with the lecturer or gradual de-ritualization? Biology students’ engagement with construction and data interpretation graphing rou…
2021
Abstract Through a commognitive lens, we examine twelve first-semester biology students’. engagement with graphing routines as they work in groups, during four sessions of Mathematical Modelling (MM). We trace the students’ meta-level learning, particularly as they fluctuate between deploying graphs for mere illustration of data and as sense-making tools. We account for student activity in relation to precedent events in their experiences of graphing and as fluid, if not always productive, interplay between ritualised and exploratory engagement with graph construction and interpretation routines. The students’ construal of the task situations is marked by efforts to keep up with lecturer ex…
Creation of a brand model through SEM to predict users' loyalty and recommendations regarding a public sports service.
2021
Brand perception is a key element in achieving business success: how a brand is perceived by current and potential users determines what they think and their disposition towards the brand. The users' perception also determines whether they will perceive the sports service as offering a greater quality or value than other services, whether they will be more loyal, or whether they will recommend the service. This paper analyses the brand perception of users of a public sports service, creating a model of structural equations that analyses how credibility and trust influence a user's congruence with the brand and the generation of positive attitudes towards the brand and how these variables in…
Urban organic aerosol composition in eastern China differs from north to south:Molecular insight from a liquid chromatography-mass spectrometry (Orbi…
2021
Air pollution by particulate matter in China affects human health, the ecosystem and the climate. However, the chemical composition of particulate aerosol, especially of the organic fraction, is still not well understood. In this study, particulate aerosol samples with a diameter of ≤2.5 µm (PM2.5) were collected in January 2014 in three cities located in northeast, east and southeast China, namely Changchun, Shanghai and Guangzhou. Organic aerosol (OA) in the PM2.5 samples was analyzed by an ultrahigh-performance liquid chromatograph (UHPLC) coupled to a high-resolution Orbitrap mass spectrometer in both negative mode (ESI-) and positive mode electrospray ionization (ESI+). After non-targe…

Bipolar membrane reverse electrodialysis for the sustainable recovery of energy from pH gradients of industrial wastewater: Performance prediction by…
2021
Abstract The theoretical energy density extractable from acidic and alkaline solutions is higher than 20 kWh m−3 of single solution when mixing 1 M concentrated streams. Therefore, acidic and alkaline industrial wastewater have a huge potential for the recovery of energy. To this purpose, bipolar membrane reverse electrodialysis (BMRED) is an interesting, yet poorly studied technology for the conversion of the mixing entropy of solutions at different pH into electricity. Although it shows promising performance, only few works have been presented in the literature so far, and no comprehensive models have been developed yet. This work presents a mathematical multi-scale model based on a semi-…
Effetti della tecnologia Modified Atmosphere Packaging a base di argon sulla qualità degli arilli di melograno (Punica granatum L. cv. Wonderful)
2021
La coltivazione del melograno è aumentata globalmente nell’ultimo decennio grazie ai rinomati benefici del frutto per la salute. Il consumo del melograno come frutto fresco, però, incontra delle resistenze da parte dei consumatori a causa della scomodità di estrazione degli arilli dal frutto e della presenza di metaboliti fenolici che possono macchiare le mani. Oggi si sta diffondendo sempre più il consumo di arilli pronti al consumo, pratici e veloci in confezionamento protettivo per cui occorre mantenere inalterate le caratteristiche qualitative del frutto fresco. Il confezionamento in atmosfera modificata (MAP) è stato utilizzato negli ultimi anni per mantenere la qualità della frutta di…
Exploring the linkage between dew point temperature and precipitation extremes: A multi-time-scale analysis on a semi-arid Mediterranean region
2021
Abstract Understanding warming climate implications on precipitation is of crucial importance, especially for areas particularly subjected to climate changes and land use/cover modifications, which could be extremely vulnerable to phenomena typically caused by rainfall extremes, such as floods and landslides. Past decade has been witnessing an increasing interest on simple modeling approaches based on the observation of commonly available meteorological variables and their physical linkages. In particular, based on the well-known thermodynamic Clausius-Clapeyron (CC) equation, it was widely investigated the scaling relation between rainfall extremes and variables representative of the near …
Angioedema Coexisting Chronic Spontaneous Urticaria Negatively Influences Patients’ Sense of Coherence, What Results in Susceptibility to Anxiety Sym…
2021
Background: Angioedema coexisting chronic spontaneous urticaria (CSU) is proved to result in patient anxiety occurrence, but the mechanisms and susceptibility patterns are unknown. Sense of coherence (SOC) is one of methods of coping with stress and is defined as a person’s general orientation toward life. We decided to assess SOC disturbances in CSU patients in the context of possible angioedema association. Methods: The study comprised 71 CSU subjects. To analyze disease activity, the Urticaria Activity Score seven-day assessment questionnaire (UAS7) was used. For anxiety assessment, the STAI questionnaire was used. The SOC-29 questionnaire, consisting of questions related to comprehensib…
The Representation of Roma in the Romanian Media During COVID-19: Performing Control Through Discursive-Performative Repertoires
2021
This article investigates the narratives employed by the Romanian media in covering the development of COVID-19 in Roma communities in Romania. This paper aims to contribute to academic literature on Romani studies, particularly in Central and Eastern Europe, by adopting as its case study the town of Ţăndărei, a small town in the south of Romania, which in early 2020 was widely reported by Romanian media during both the pre- and post-quarantine period. The contributions rest on anchoring the study in post-foundational theory and media studies to understand the performativity of Roma identity and the discursive-performative practices of control employed by the Romania media in the first half…
Vetting and verifying multimodal false information. A challenge for democratic societies
2021
The rapid proliferation of fake news is a challenge for free societies, founded on freedom of expression and information, endangering their democratic systems through audience confusion. Fake news is a type of disinformation with the ability to alter the logical orientation of readers, and as evidenced in different academic publications, it can radicalize the citizen and favour violence. This news is also created to confuse audiences and reinforce certain trends. This is important enough to produce a scientific interest in information science studies and urge the creation of tools capable of detecting and identifying this type of news, especially those disseminated by social networks, where…
Garnet as a monitor for melt–rock interaction: Textural, mineralogical, and compositional evidence of partial melting and melt‐driven metasomatism
2021
International audience; In this study, we focus on a partially melted garnet-bearing granulite from the Salvador–Esplanade Belt (Salvador da Bahia, Brazil), and examine the behaviour of major and trace elements during partial melting and melt-driven metasomatism. Phase equilibria modelling and U–Th– Pb geochronology show that the sample underwent partial melting during the heating segment of the decompression path from ~1.2 GPa and 675–700° C to ~0.8 GPa and 790°C at c. 2.06 Ga. During the final stage of decompression, from 0.8 to ~0.5 GPa, physical segregation of melt resulted in the establishment of chemical potential gradients and mass transfer between the host granulite and the leucosom…

Guaranteed and computable error bounds for approximations constructed by an iterative decoupling of the Biot problem
2021
The paper is concerned with guaranteed a posteriori error estimates for a class of evolutionary problems related to poroelastic media governed by the quasi-static linear Biot equations. The system is decoupled by employing the fixed-stress split scheme, which leads to an iteratively solved semi-discrete system. The error bounds are derived by combining a posteriori estimates for contractive mappings with functional type error control for elliptic partial differential equations. The estimates are applicable to any approximation in the admissible functional space and are independent of the discretization method. They are fully computable, do not contain mesh-dependent constants, and provide r…
Dance movement therapy for depressed clients : Profiles of the level and changes in depression
2021
This research identified participant profiles in level and changes in depression among working age (18–64 years old) clients (N = 137) diagnosed with depression, who participated in a 20-session dance movement therapy (DMT) intervention. Using Latent Profile Analysis Mild, sharply reducing depression (9%), Mild, reducing depression (58%) and Severe, reducing depression (33%) profiles were established, using Beck Depression Inventory scores gathered at pre-intervention, post-intervention, and follow-up points. At the pre-intervention point, being in full-time work was related to the Mild, sharply reducing depression profile. Being on a disability pension, having a history of one's own or a c…
A New Score Unveils a High Prevalence of Mild Cognitive Impairment in Patients with Nonalcoholic Fatty Liver Disease

Patients with nonalcoholic fatty liver disease (NAFLD) may show mild cognitive impairment (MCI). The neurological functions affected remain unclear. The aims were to: (1) Characterize the neuropsychological alterations in NAFLD patients; (2) assess the prevalence of impairment of neurological functions evaluated; (3) develop a new score for sensitive and rapid MCI detection in NAFLD; (4) assess differences in MCI features between patients with nonalcoholic fatty liver (NAFL) and nonalcoholic steatohepatitis (NASH); and (5) compare neuropsychological alterations in NAFLD patients with cirrhotic patients with MCI. Fifty-nine NAFLD patients and 53 controls performed psychometric tests assessin…
Closeness to Parents and Experiencing Threats with COVID-19 Mediates the Link between Personality and Stress among Adolescents
2021
Purpose: many researchers have already established that the 2019 COVID-19 pandemic poses a threat to adolescent psychological health. Studies on the COVID-19 pandemic mainly focus on individual psychological consequences, such as anxiety, depression or stress. The presented study added a family context to psychological analyses of the COVID-19 pandemic in adolescence. We examined the mediational effects of closeness to parents and perceived pandemic-related threats to relationships between personality (emotional stability and agreeableness) and stress in adolescents. Methods: in total, 413 students from secondary schools in southern Poland completed questionnaires measuring stress, personal…

Abstract Funding Acknowledgements Type of funding sources: None. Background. In recent guidelines, non-invasive imaging techniques play a pivotal role in the management of chronic coronary syndrome (CCS). The elderly represent a large percentage of our routine CCS population and risk stratification in this scenario is challenging. The potential of vasodilator stress cardiovascular magnetic resonance (CMR) for this purpose is unknown. Purpose. We explore the prognostic value and the usefulness for decision-making of the ischemic burden determined by vasodilator stress CMR imaging in a large cohort of elderly patients with known or suspected CCS. Methods. The study group was made up of 2496 p…
El derecho a morir dignamente: una oportunidad para el impulso ético del Trabajo Social
2021
La creciente importancia de las enfermedades crónicas como causa de muerte y la atención que actualmente se presta al final de la vida han creado interés en el papel de las disciplinas sociosanitarias en el momento y el modo de muerte. En la actualidad, pocos países han legalizado o despenalizado la eutanasia y el suicidio asistido. Este artículo realiza una revisión narrativa con el objetivo de conocer los aspectos éticos y jurídicos que envuelven el derecho a morir dignamente, el suicidio asistido y la eutanasia en los países donde se han regulado estas prácticas, así como su vinculación con los principios éticos inherentes al Trabajo Social. Los resultados muestran que estas prácticas de…
Combining Ergonomic Risk Assessment (RULA) with Inertial Motion Capture Technology in Dentistry—Using the Benefits from Two Worlds
2021
Traditional ergonomic risk assessment tools such as the Rapid Upper Limb Assessment (RULA) are often not sensitive enough to evaluate well-optimized work routines. An implementation of kinematic data captured by inertial sensors is applied to compare two work routines in dentistry. The surgical dental treatment was performed in two different conditions, which were recorded by means of inertial sensors (Xsens MVN Link). For this purpose, 15 (12 males/3 females) oral and maxillofacial surgeons took part in the study. Data were post processed with costume written MATLAB® routines, including a full implementation of RULA (slightly adjusted to dentistry). For an in-depth comparison, five newly i…
Presentazione dell’edizione italiana di storia della Sicilia da Odisseo ai giorni nostri di Jean-Yves Frétigné
2021
Published for the first time in 2009, for the Fayard types, and re-edited in 2018 in a "pocket" format, this History of Sicily by Jean-Yves Frétigné, with the subtitle from Odysseus to the present day, presented to the French public as an easy consultation, a "Compagnon de voyage" destined to have an excellent editorial success with over 8,000 copies sold.The Italian translation presented here does not have the presumption of concurring with the monumental works of the history of Sicily which constitute an essential reference by the same Author, as the rich bibliography in the appendix to the volume clearly testifies. Rather, it intends to offer, in just over 400 pages, the “external” look …
Semi-natural habitats in boreal Europe: a rise of a social-ecological research agenda
2021
The European continent contains substantial areas of semi-natural habitats, mostly grasslands, which are among the most endangered habitats in Europe. Their continued existence depends on some form of human activity, for either production or conservation purposes, or both. We examined the share of semi-natural grasslands within the general grassland areas in boreal Europe. We reviewed research literature across the region to compile evidence on semi-natural grasslands and other semi-natural habitats, such as wooded pastures, in respect to a range of topics such as ecology, land-use change, socioeconomics, and production. We also explored drivers of the research agenda and outlined future re…
