Experimental investigation on dispersion mechanisms in rigid and flexible vegetated beds
2018
Vegetation in channels strongly affects flow structure and turbulence, with consequences on the hydrological storage of nutrients and chemical tracers, the shelter of stream biota as well as the trapping or transport of sediments. At the same time, all these phenomena are inevitably subjected to alteration of hydrological conditions in fluvial systems due to climate change. The present study intends to provide a thorough investigation into the processes of transport and dispersion induced by flow turbulence within the vegetation structure. Specifically, velocity measurements in vegetated channels were intensively conducted and analyzed in the case of both flexible submerged and rigid emerge…

User evaluation of a therapist-guided internet-delivered treatment program for anxiety disorders: A qualitative study
2021
Therapist-guided internet-based cognitive behaviour therapy (ICBT) has been proposed as a potential means to increase individuals' access to quality mental health care and effective treatment. Guided ICBT aims to increase a patient's knowledge and competence to better cope with their disorder. Despite the growing evidence supporting the effects of guided ICBT, there is remarkably little research on the different factors that are important for patients to achieve effects from using such digital treatment interventions. Thus, the aim of this study was to conduct a user evaluation of a therapist-guided ICBT program using the updated DeLone and McLean (D&M) model for measuring information syste…
Comparing Surface and Fine-Wire Electromyography Activity of Lower Leg Muscles at Different Walking Speeds.
2019
Ankle plantar flexor muscles are active in the stance phase of walking to propel the body forward. Increasing walking speed requires increased plantar flexor excitation, frequently assessed using surface electromyography (EMG). Despite its popularity, validity of surface EMG applied on shank muscles is mostly unclear. Thus, we examined the agreement between surface and intramuscular EMG at a range of walking speeds. Ten participants walked overground at slow, preferred, fast, and maximum walking speeds (1.01 ± 0.13, 1.43 ± 0.19, 1.84 ± 0.23, and 2.20 ± 0.38 m s–1, respectively) while surface and fine-wire EMG activities of flexor hallucis longus (FHL), soleus (SOL), medial gastrocnemius (MG…
CEFLES2: The remote sensing component to quantify photosynthetic efficiency from the leaf to the region by measuring sun-induced fluorescence in the …
2009
The CEFLES2 campaign during the Carbo Europe Regional Experiment Strategy was designed to provide simultaneous airborne measurements of solar induced fluorescence and CO<sub>2</sub> fluxes. It was combined with extensive ground-based quantification of leaf- and canopy-level processes in support of ESA's Candidate Earth Explorer Mission of the "Fluorescence Explorer" (FLEX). The aim of this campaign was to test if fluorescence signal detected from an airborne platform can be used to improve estimates of plant mediated exchange on the mesoscale. Canopy fluorescence was quantified from four airborne platforms using a combination of novel sensors: (i) the prototype ai…
Turning Migration Disadvantage into Educational Advantage. Autobiographies of Successful Students with an Immigrant Background
2018
The article focuses on unexpected pathways of successful students with an immigrant background, in order to investigate the implication of this phenomenon from a theoretical, methodological and empirical point of view. After a review of the main sociological studies on “immigrant optimism” towards educational success, I will reflect on biographical approach, particularly suitable to study this topic. A on-going research project based on the collection of educational autobiographies of successful immigrant-origin students, attending upper secondary schools in Northern Italy, is presented. Then, the story of Destiny, a 16 years-old girl with Moroccan origin, is used as a case study to explore…
In situ structural analysis of SARS-CoV-2 spike reveals flexibility mediated by three hinges
2020
Flexible spikes The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein enables viral entry into host cells by binding to the angiotensin-converting enzyme 2 (ACE2) receptor and is a major target for neutralizing antibodies. About 20 to 40 spikes decorate the surface of virions. Turoňová et al. now show that the spike is flexibly connected to the viral surface by three hinges that are well protected by glycosylation sites. The flexibility imparted by these hinges may explain how multiple spikes act in concert to engage onto the flat surface of a host cell. Science, this issue p. 203
In situ structural analysis of SARS-CoV-2 spike reveals flexibility mediated by three hinges
2020
AbstractThe spike (S) protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is required for cell entry and is the major focus for vaccine development. We combine cryo electron tomography, subtomogram averaging and molecular dynamics simulations to structurally analyze Sin situ. Compared to recombinant S, the viral S is more heavily glycosylated and occurs predominantly in a closed pre-fusion conformation. We show that the stalk domain of S contains three hinges that give the globular domain unexpected orientational freedom. We propose that the hinges allow S to scan the host cell surface, shielded from antibodies by an extensive glycan coat. The structure of native S contr…
Valutazione partecipata e continuità nei servizi educativi zero-sei: una ricerca-intervento in un quartiere della città di Palermo
2021
RIASSUNTO In questo articolo verrà condotta inizialmente una riflessione sulla funzione della valutazione di contesto sia in termini formativi individuali e di gruppo, sia in termini di cambiamento organizzativo, adottando una prospettiva ecologica e sistemica. Successivamente, attraverso la narrazione di un percorso di ricerca sulla costruzione di un possibile curricolo zero-sei, condotta per tre anni con un gruppo di insegnanti di scuola dell’infanzia statale ed un gruppo di educatrici di un nido comunale operanti nello stesso territorio (un quartiere del centro storico di Palermo), verranno messi in luce e problematizzati ambiti di continuità e di discontinuità tra i due servizi educativ…
INCLUSIVE PEDAGOGY AND TEACHER TRAINING TOWARDS HIGH QUALITY EDUCATION PROCESSES.A RESEARCH WITH FUTURE SUPPORT TEACHERS
2022
Fornire un’educazione di qualità, equa ed inclusiva e opportunità di apprendimento per tutti è la base per migliorare la vita delle persone e raggiungere lo sviluppo sostenibile. Forte degli insegnamenti trattidagli Obiettivi di Sviluppo del Millennio (OSM), l’obiettivo 4 dell’Agenda 2030 non si limita all’istruzione primaria, ma fotografa in modo completo tutti i passi che sono necessari per garantire, in ogni parte del mondo, un'educazione di qualità, equa e accessibile a tutti. In tale contesto è fondamentale una particolare attenzione allo sviluppo delle competenze degli insegnanti e della loro capacità riflessiva e di lettura critica della propria esperienza professionale. Gli approcci…
