Gamifying Teacher Students’ Learning Platform
2020
This paper presents initial results from a study exploring teacher students’ experiences related to the gamification of an online learning platform in higher education. The aim was to get an understanding of the participants’ views regarding the use of game elements and to examine the user type profile of this group in order to explore the potential of applying user types in planning gamification solutions for teacher students. The participants’ overall experience of having game elements as part of their course platform was principally positive. User types students presented were investigated using the Hexad scale adapted from game design: in this user group, Socialiser and Philanthropist w…
Le camere dello scirocco: archetipi bioclimatici della Palermo antica
2014
"Scendesi più in basso a man destra vi è una grotta seu camera di scirocco con fontana in mezzo e tutto un giro di mattoni di Valenza e più sopra un lavoro di crocchiole con diversi animali per buttar l’acqua". Queste parole di un atto notarile del 1691 fanno, per la prima volta, riferimento alla 'camera dello scirocco’, singolare esempio di archetipo per il raffrescamento passivo e parte di un inestimabile patrimonio, eredità di secoli di storia e del succedersi di popoli che hanno fatto di Palermo una città d'arte e cultura. Strutture ipogee che, insieme ad altri capolavori di ingegneria presenti nel sottosuolo palermitano, testimoniano quanto le potenzialità dell'ingegno umano siano in g…
A review of the importance of mineral nitrogen cycling in the plant-soil-microbe system of permafrost-affected soils : changing the paradigm
2022
The paradigm that permafrost-affected soils show restricted mineral nitrogen (N) cycling in favor of organic N compounds is based on the observation that net N mineralization rates in these cold climates are negligible. However, we find here that this perception is wrong. By synthesizing published data on N cycling in the plant-soil-microbe system of permafrost ecosystems we show that gross ammonification and nitrification rates in active layers were of similar magnitude and showed a similar dependence on soil organic carbon (C) and total N concentrations as observed in temperate and tropical systems. Moreover, high protein depolymerization rates and only marginal effects of C:N stoichiomet…
Gaia-ESO Survey: Global properties of clusters Trumpler 14 and 16 in the Carina nebula
2017
Aims: We present the first extensive spectroscopic study of the global population in star clusters Trumpler 16, Trumpler 14, and Collinder 232 in the Carina nebula, using data from the Gaia-ESO Survey, down to solar-mass stars. Methods: In addition to the standard homogeneous survey data reduction, a special processing was applied here because of the bright nebulosity surrounding Carina stars. Results: We find about 400 good candidate members ranging from OB types down to slightly subsolar masses. About 100 heavily reddened early-type Carina members found here were previously unrecognized or poorly classified, including two candidate O stars and several candidate Herbig Ae/Be stars. Their l…
HADES RV programme with HARPS-N at TNG: XII. The abundance signature of M dwarf stars with planets
2020
[Context] Most of our current knowledge on planet formation is still based on the analysis of main sequence, solar-type stars. Conversely, detailed chemical studies of large samples of M dwarfs hosting planets are still missing.
The role of melt composition on aqueous fluid vs. silicate melt partitioning of bromine in magmas
2018
International audience; Volcanogenic halogens, in particular bromine, potentially play an important role in the ozone depletion of the atmosphere. Understanding bromine behaviour in magmas is therefore crucial to properly evaluate the contribution of volcanic eruptions to atmospheric chemistry and their environmental impact. To date, bromine partitioning between silicate melts and the gas phase is very poorly constrained, with the only relevant experimental studies limited to investigation of synthetic melt with silicic compositions. In this study, fluid/melt partitioning experiments were performed using natural silicate glasses with mafic, intermediate and silicic compositions. For each co…

The genotypes and virulence attributes of C. albicans isolates from oral leukoplakia
2021
Background There is a debate as to whether some types of oral leucoplakias (OL) are caused by Candida species, and whether they contribute to the malignant transformation, associated with a minority of such lesions. As no detailed population analysis of yeast isolates from OL is available, we evaluated the virulence attributes, and genotypes of 35 C. albicans from OL, and compared their genotypes with 18 oral isolates from healthy individuals. Material and Methods The virulence traits evaluated were esterase, phospholipase, proteinase, haemolysin and coagulase production, and phenotypic switching activity, and yeast adherence and biofilm formation. DNA from OL and control yeasts were evalua…
An SVM Ensamble Approach to Detect Irony and Stereotype Spreaders on Twitter
2022
The problem we address in this work is classifying whether a Twitter user has spread Irony and Stereotype or not. We used a text vectorization layer to generate Bag-Of-Words sequences. Then such sequences are passed to three different text classifiers (Decision Tree, Convolutional Neural Network, Naive Bayes). Our final classifier is an SVM. To test and validate our approach we used the dataset provided for the author profiling task organized by PAN@CLEF 2022. Our team (missino) submitted the predictions on the provided test set to participate at the shared task. Over several cross fold validation our approach was able to reach a maximum binary accuracy on the best validation split equal to…
Postmodernistyczna kultura i jej wpływ na nurty pedagogiczne – wyzwania i dylematy współczesnego pedagoga
2017
Artykuł porusza istotne problemy związane z kontekstami kultury postmodernistycznej i jej wpływem na nowe nurty pedagogiczne, ze szczególnym zwróceniem uwagi na wyzwania i dylematy współczesnego pedagoga. Relewantne są rozważania dotyczące kultury toksycznej, w stosunku do której można użyć tautologicznego stwierdzenia, że jest ona „ kulturą” nie kulturalną. Wpływ tej kultury, lansowanej w mediach, jest jednak wszechobecny i to on kształtuje postawy przyszłych pedagogów – strategów „nowych” koncepcji pedagogicznych, a także systemów oświatowych
