L’innovazione tecnologica e il Faculty Development.

2023

La crisi pandemica ha accelerato la diffusione di ambienti di apprendimento caratterizzati dall'uso intensivo della tecnologia. Questa novità rappresenta un obiettivo trasversale della professionalizzazione del docente universitario, con una particolare declinazione sul versante pedagogico-didattico-valutativo quale questione strategica per lo sviluppo dell’alta formazione. Il contributo illustra i risultati di una ricerca condotta con 119 docenti universitari neoassunti e 20 Direttori di dipartimento. La finalità della ricerca è stata, da una parte, rilevare la percezione dei docenti neoassunti relativa alle proprie competenze didattiche, metacognitive e valutative, con riferimento alla di…

The pandemic crisis has accelerated the diffusion of learning environments characterized by the intensive use of technology. This novelty represents a transversal objective of the professionalization of the university teacher with a particular declination on the pedagogical-didactic-evaluation side as a strategic issue for the development of higher education. This paper presents the results of research conducted with 119 newly recruited university teachers and 20 Department Directors. The aim of the research was on the one hand to detect the perception of newly hired teachers related to their teaching metacognitive and evaluative skills with reference to distance learning to highlight specific characteristics that could have encouraged or hindered adaptation to this new condition. On the other hand through the qualitative research the aim has been to penetrate in depth the challenges posed by the digital revolution at University by carrying out 20 interviews with privileged witnesses who represent on the national scene agents of institutional change. The results showed a certain awareness of the need to integrate new ways of teaching to increase interest participation and enthusiasm for technology.Settore M-PED/03 - Didattica E Pedagogia Speciale

Traducción y recepción: Rosalía de Castro en Italia

2020

El panorama de la recepción italiana contemporánea de los poetas españoles del siglo XIX, a través de las traducciones, no resulta especialmente satisfactorio, puesto que hay que esperar el siglo siguiente para encontrar los primeros estudios monográficos y ediciones de textos en traducción, aunque en forma antológica. Ello, no obstante, así como en el resto de Europa, el corpus de las publicaciones periódicas de las revistas ofrece un canal editorial muy proficuo para la recepción de textos literarios extranjeros. Este trabajo se centra en la presencia de la obra de Rosalía de Castro en la prensa italiana contemporánea. Al mismo tiempo, se ha intentado completar el estudio de la recepción …

The panorama of the contemporary Italian reception of the Spanish poets of the 19th century through translations is not particularly satisfactory since it is necessary to wait for the following century to find the first monographic studies and editions of texts in translation although in anthological form. However as in the rest of Europe the corpus of periodicals of magazines offers a very profitable editorial channel for receiving foreign literary texts. This work focuses on the presence of Rosalía de Castro's work in the contemporary Italian press. At the same time attempts have been made to complete the study of the reception of the Galician poet in Italy collecting traces in other editorial products such as the book. The consequent analytical focus will correspond to the transnational study of some proto and meta texts individualized by their special interest.

Primo rinvenimento di Juniperus sabina L. sul massiccio del Pollino, Italia meridionale

1992

Viene segnalata per la prima volta la presenza di Juniperus sabina L. sul massiccio del Pollino, dove la specie è stata rinvenuta in habitat rupicolo in due stazioni ricadenti rispettivamente in territorio calabrese e lucano. Le stazioni vengono caratterizzate dal punto di vista floristico ed ecologico.

The presence of Juniperus sabina L. an Eurasian element is recorded from southern Italy where it has been found in two sites on Mt. Pollino. In Italy this species was so far reported only from the Alps and a few localities of central Apennines. Therefore the finding on Mt. Pollino largely widens its distribution southwards in the Italian Peninsula. As regards Europe J. sabina reaches lower latitudes only in southern Spain. The Authors stress the phytogeographical significance of the sites which are characterized from the floristic and ecological viewpoint.Settore BIO/02 - Botanica Sistematica

Interventistica eco-guidata per l’articolazione d’anca

2013

Lo scopo di questo lavoro è di rivedere le principali applicazioni della interventistica eco-guidata d’anca, descrivendone le indicazioni e la metodologia. L’ecografia è una metodica considerata sicura per i pazienti, in quanto non è stato dimostrato un possibile danno dovuto all’energia trasmessa dagli ultrasuoni ai tessuti del paziente, contrariamente alle metodiche che fanno uso di radiazioni ionizzanti, come la radiografia convenzionale e la tomografia computerizzata. Inoltre, l’ecografia risulta rapida ed efficace nel guidare l’ago verso la sede voluta evitando di intercettare strutture vascolari e/o nervose, consentendo quindi una maggiore sicurezza, rispetto alle tecniche interventis…

The purpose of this work is to review the main applications of ultrasound-guided hip intervention al procedures describing the indications and methodology. Ultrasound is a method considered safe for patients as it has not been shown a possible damage due to ultrasound energy transmitted towards the patient's tissues as opposed to methods that make use of ionizing radiation such as conventional radiography and computed tomography. In addition ultrasound is quick and effective in guiding the needle to the desired location avoiding vascular and/or nerve structures thus enabling greater security compared to the techniques performed in interventional fluoroscopy which also have the disadvantage of a large delivery of ionizing radiation for both patient and operator. Several authors have described the main techniques of ultrasound-guided hip intervention and its various applications that can be both diagnostic (as in the case of joint fluid aspiration to assess the presence or absence of septic arthritis) and therapeutic (as in the case of drugs inoculations or evacuation of exceeding intra-articular fluid).

Una storia italiana: Giorgio e Isabella

2018

Si tratta, qui, della storia di due italiani dalla “pelle scura” raccontata, per Giorgio Marincola, da Carlo Costa e Lorenzo Teodonio in Razza partigiana e, per la sorella Isabella, da Wu Ming 2 e Antar Mohamed in Timira. Romanzo meticcio. Le loro vicende, così come molti altri aspetti della nostra storia coloniale, neocoloniale e postcoloniale, sono riemerse dal buio nel quale erano state occultate solo nell’ultimo quindicennio, grazie alla riapertura degli archivi che ha permesso di ridiscutere molti degli aspetti che nelle pagine di Storia, così come in quelle letterarie, erano stati raccontati in altro modo. I due testi, che hanno inevitabilmente finito per incontrarsi e che potremmo in…

This paper focuses on the story of two dark-skinned Italians written for Giorgio Marincola by Carlo Costa and Lorenzo Teodonio in Razza partigiana and for his sister Isabella by Wu Ming 2 and Antar Mohamed in Timira. Romanzo meticcio. The events of their lives as well as many other aspects of our colonial neocolonial and postcolonial history have re-emerged from the darkness in which they had been hidden only in the last fifteen years thanks to the reopening of the archives allowing to re-discuss many of the aspects that in the pages of History as well as in those of literature had been told in another way. The two works that could be inserted into the current defined as the "new Italian epic" dismantle a series of clichés and prejudices and invite us to reflect on the concept of Italian identity on colonialism and its consequence in the short and long term and particularly on racism.Settore L-FIL-LET/14 - Critica Letteraria E Letterature Comparate

Improved Beerkan run methodology to assess water impact effects on infiltration and hydraulic properties of a loam soil under conventional- and no-ti…

2021

Beerkan infiltration experiments with three water pouring heights (low, L = 3 cm; intermediate, M = 100 cm; high, H = 200 cm) were performed on both a no-tilled (NT) and a conventionally tilled (CT) bare loam soil to determine the surface soil hydraulic properties by the BEST-steady algorithm. Saturated soil hydraulic conductivity, Ks, significantly and monotonically decreased from the L to the H runs (from 236 to 37 mm h‒1) and lower Ks values were detected under CT (163–23 mm h‒1) than NT (346–51 mm h‒1) for each water pouring height. For both soil management practices, the gravitational potential energy, Ep, of the water used for the infiltration runs, explained most of the variance in t…

Popolamenti marginali di faggio e cambiamenti climatici: criticità dell’applicazione di pratiche colturali classici in ambiente mediterraneo (Sicilia)

2013

Il faggio (Fagus sylvatica) è tra le specie forestali più importanti d’Europa per distribuzione, selvicoltura, rilevanza paesaggistica. Il faggio in Sicilia raggiunge il limite meridionale del proprio areale, nonché le quote altitudinali più elevate in Europa (timberline intorno a 2000 s.l.m.), localizzandosi sui Monti Nebrodi, Madonie ed Etna. La maggior parte di questi soprassuoli è stata tradizionalmente governata a ceduo semplice matricinato, seppur raramente all’interno di un quadro di interventi pianificati di lungo periodo, e molti popolamenti recentemente hanno subito primi interventi di avviamento alla conversione a fustaia. L’assetto attuale di questi soprassuoli è tuttavia destin…

Functional implications of the staminal lever mechanism in Salvia cyclostegia (Lamiaceae)

2011

Flower morphology and inflorescence architecture affect pollinator foraging behaviour and thereby influence the process of pollination and the reproductive success of plants. This study explored possible ecological functions of the lever-like stamens and the floral design in Salvia cyclostegia.Flower construction was experimentally manipulated by removing either the lower lever arms or the upper fertile thecae of the two stamens from a flower. The two types of manipulated individuals were intermixed with the control ones and randomly distributed in the population.Removing the sterile lower lever arms significantly reduced handling time per flower of the main pollinator, Bombus personatus. I…

Insect venom immunotherapy induces interleukin-10 production and a Th2-to-Th1 shift, and changes surface marker expression in venom-allergic subjects.

1997

Abstract The current study was carried out to elucidate the immunoregulatory changes induced by venom immunotherapy (VIT) in bee or wasp allergic subjects. All subjects included in this study had a history of severe systemic allergic reactions to stings of the respective insect as well as positive skin tests with the respective venom or venom-specific IgE in the sera. Parameters assessed in peripheral blood mononuclear cells (PBMC) before and after initiation of VIT (rush therapy reaching a maintenance dose of 100 micrograms venom injected subcutaneously within 1 week) were expression of CD3, CD4, CD8, CD45RA, CD45RO, interleukin (IL)-2 receptor (R) alpha, IL-4R, IL-12R, Fc epsilon RII, CD4…

Preliminary Estimation of Deoxynivalenol Excretion through a 24 h Pilot Study

2015

A duplicate diet study was designed to explore the occurrence of 15 Fusarium mycotoxins in the 24 h-diet consumed by one volunteer as well as the levels of mycotoxins in his 24 h-collected urine. The employed methodology involved solvent extraction at high ionic strength followed by dispersive solid phase extraction and gas chromatography determination coupled to mass spectrometry in tandem. Satisfactory results in method performance were achieved. The method"s accuracy was in a range of 68%108%, with intra-day relative standard deviation and inter-day relative standard deviation lower than 12% and 15%, respectively. The limits of quantitation ranged from 0.1 to 8 μg/Kg. The matrix effect w…
