Controllore o compagno di apprendimento? La funzione dell'insegnante in una scuola “senza voti”
No full textEducational research has shown how the processes of assessment, teaching and learning are deeply interlinked. It is therefore evident that a change in assessment processes has an impact on the teaching and learning processes that take place in that specific school context where the change in assessment is realised. The present research starts in a secondary school in which, from the school year 2023/2024, an experiment in narrative assessment has been initiated. The school has chosen not to employ numerical grading in ongoing assessment, replacing it with narrative feedback. The research therefore aims to explore the impact of this assessment experimentation on the teacher's role and teaching approaches. Through the use of a questionnaire and possible interviews, teachers‘ and students’ perceptions of the teacher's role and its possible changes with the beginning of the experimentation are surveyed
Food insecurity and risk management of smallholder farming systems in Ethiopia
No full textAgriculture is the economic mainstay of Ethiopia. About 80% of the Ethiopian population depends on smallholder agriculture whilst about 6 million of people are food insecure due to limited availability and access to food. Food insecurity has complex interfaces with environment, climate, economy, health, gender etc. Through the study of farming systems and livelihoods in two Ethiopian food insecure areas, a suited methodology is presented how to incorporate livelihoods into vulnerability and how to match economic and social dimensions with environmental and spatial analysis. The results show natural, market and health shocks constitute a major challenge to rural economy

Flowering synchrony as a trick to enhance species richness in dry meadows
No full textGiven the growing consensus on the positive effect of biodiversity on ecosystem functioning (Balvanera et al. 2006; Cardinale et al. 2012), species richness and loss are among the simplest and most used measures of habitats evaluation. Species diversity in a plant community is assumed to be determined by two sets of factors. The first refers to the “species pool”, i.e. the set of propagules able to reach a site. The second comprises local ecological interactions and select species from the pool that are able to coexist. In this ‘community filter’, both abiotic and
biotic factors operate. Among biotic factors facilitation may increase the diversity of a community (Stachowicz, 2001). Such enhancement can be produced through facilitation via shared pollinators among co-flowering entomophilous species.
We evaluated the role of flowering synchrony in determining species richness and coverage at the community level in dry meadows (Festuco-Brometea) (Habitat 6210). In particular we tested if 1. there is a non-random flowering pattern at the community level; 2. both the presence
and percentage cover of different insect-pollinated species are affected by flowering synchrony.
The study was carried out in the Euganei Hills district (NE Italy). 45 plots (2x2m) were randomly placed over dry meadows and data on species richness and percentage cover were collected. Flowering phenology of all entomophilous species was monitored every 10 days during the growing season (April, 1st to September, 30th 2013). Flowering was considered started when the first flower opened on an individual plant and terminated
when individuals no longer possessed flowers with anthers (Dante et al., 2013). To estimate flowering time overlap at the community level a mean Co-flowering index (V score; Lepš, Šmilauer, 2003) was performed between all possible pairs of monitored species. The significance of flowering overlap pattern was tested using a null model (Gotelli, Graves, 1996). For each plot a Co-flowering index was than computed.
Spearman’s rank correlation was used to test for a relationship between the V score and the number (and percentage cover) of insect-pollinated species per plot. Species were classified in six groups according to Müeller’s (1881) classification, which groups nectariferous flowers according to the depth of nectar display. Six classes were recognized as follows: a) pollen flowers, b) flowers with exposed nectar, c) flowers with partly hidden nectar, d) flowers with totally hidden nectar, e) Hymenoptera flowers and f) Lepidoptera flowers. Only rough groups of pollinators are assigned to the first four groups, which differ in length of proboscis, while smaller pollinator range characterizes classes e) and f).
A non random flowering pattern has been observed at the community level among entomophilous species (pvalue<0.001).
In particular, richness and percentage cover of Hymenoptera flowers turned out to be positive related to Coflowering index (p=0.001 and p=0.02 respectively), while no significant correlations were observed for the other groups of species.
In conclusion, our results show that flowering synchrony may play an important role in controlling and enhancing Hymenoptera pollinated species richness in Euganean dry meadows
Didattica e ricerca. L’esperienza del Laboratorio aragonese e sforzesco
No full textIn the workshop on Diplomatic correspondences in the Italian Renaissance, directed in January-May 2018 by Francesco Storti and Francesco Senatore in the Istituto italiano per gli studi filosofici of Naples, 12 undergraduate and graduate students learned to read and trascribe italian diplomatic dispatches of the 15th cent., producing a specimen of scientific edition. In the opinion of the author, such activities and similar ones are very useful for future school teachers and scholars and they could be introduced in the university and pHD courses of history. Students of humanistic sciences should have concrete contacts with the historical research on primary sources. On the other hand, editing of historical sources could become a marginal activity because it is not enough appreciated in the current research evaluation processes.

LA MADONNA ESTERHAZY DI RAFFAELLO

Fotografie di Sergio Oriani
Il curatore della mostra, Stefano Zuffi, ha voluto inquadrare criticamente l’opera di Raffaello
proveniente dal Museo di Budapest, ponendola tra la Vergine delle Rocce di Francesco Melzi,
proveniente dall’Istituto delle Suore Orsoline di Milano e la Madonna della Rosa di Giovanni
Antonio Boltraffio, proveniente dal Museo Poldi Pezzoli della stessa città. L’architetto Corrado
Anselmi ha progettato un affascinante allestimento, concependolo come un percorso che si
sviluppa attraverso tre soste utili all’ammirazione delle opere. L’autore Francesco Murano,
spiega con ricchezza di particolari i vincoli del progetto illuminotecnico e le scelte luministiche.Once again, for the Christmas season, the Municipally of Milan decided to display an important work in the frame of the Palazzo Marino’s Alessi Hall. For this year 2014, the choice has been to propose the Estheràzy Madonna by Raphael, from the Museum of Budapest.
The exhibition curator, Stefano Zuffi, wanted to critically frame to work of Raphael by placing it between the Vegine delle Rocce (Virgin of the Rocks) by Francesco Melzi, coming from the Milan’s Istituto delle Suore Orsoline, and the Madonna della Rosa by Giovanni Boltraffio, from the Milanese Museo Poldi Pezzoli.
The Architect Corrado Anselmi designed a fascinating display, convinced as a path that develops through three stops that are useful for the enjoyment of the works.

Phantasy, Multiverse and Protopia: Ran Slavin's Israeli Futurism
No full textThe essay discusses Israeli artist Ran Slavin's transmedia production, since the 1990s, as a key example of Israeli Futurism. The essay contextualizes Slavin's films, multimedia installations, photography, soundscapes, CGI imagery, and tech-based output as a way to process the conflictual dynamics at the basis of the foundation of Israel, the mythologies of Judaism and the ongoing metamorphosis of Jewish identity. The author of this essay, Francesco Spampinato, is also the editor of this major retrospective monograph on Slavin's work
