Ten Years of Participatory Cinema as a Form of Political Solidarity with Refugees in Italy. From ZaLab and Archivio Memorie Migranti to 4CaniperStrada

This paper introduces the context of European mobilizations for and against refugees and how participatory cinema has become a way of expressing political solidarity with refugees in Italy. We present and discuss ten years of the artistic work of ZaLab and Archivio Memorie Migranti and focus on two film projects of 4CaniperStrada. Central to the production of participatory cinema in Italy is challenging the mainstream narrative of migration through the proactive involvement of asylum seekers, with their political subjectivity, by using a self-narrative metho

Architettura sacra mediobizantina dal Monte Athos (Grecia), il caso di Ravdouchos

Riassunto: La penisola di Athos, compresa nella regione della Grecia chiamata Calcidica, è da oltre un millennio custode di una tradizione monastica autoctona fondata sull’eremitismo ed evolutasi nei secoli fino alla costituzione di una vera e propria Repubblica, incentrata sulla sovranità di venti sacri monasteri e attualmente subordinata allo Stato Ellenico. La protezione offerta dall’Impero Bizantino nei secoli, il ruolo di santuario della Chiesa cristiana Ortodossa e le strette norme che attualmente regolano l’afflusso dei pellegrini hanno reso possibile la tutela del patrimonio storico, artistico ed archeologico di Athos, dall’età classica fino ai giorni nostri. In questo intervento si fornisce una descrizione di Ravdouchos, centro di ridotte dimensioni riferibile a una fondazione monastica di minore entità ed ascrivibile all’età mediobizantina (secc. VIII - XIII).Parole chiave: Monte Athos Ravdouchou Ravdouchos KellionAbstract: The peninsula of Athos, administrately belonging to Halkidiki Prefecture (Greece), had preserved for over a millennium an autochthonous monastic tradition, settled on eremitic shape and then developed by centuries until the constitution of a Monastic Republic. A rich list of architectural, artistic, archaeological and historical evidences were preserved during Athos’ existence by protection offered by Byzantine Emperors and the role of Athos itself as the main sanctuary of the Christian Orthodox Church. In this article Marco Muresu provides to give a description of an example of middle-byzantine building, its art and architecture.Keywords: Mount Athos Ravdoucho

Quantificazione dell'azotofissazione della sulla in Sardegna: azoto fissato nella fitomassa epigea ed effetto dell'inoculazione

An important and economic source of nitrogen for Mediterranean crop and forage systems arises from symbiotic nitrogen fixation, which contributes also to a high environmental protection and sustainability. This papers refers on the quantification of nitrogen fixation in sweetvetch, by the isotopic dilution and nitrogen balance methods. In addition, the effect of sweetvetch inoculation with a Sardinian strain of Rhizobium sullae was evaluated against an uninoculated treatment. The potential of nitrogen fixation in sweetvetch, estimated by the isotopic dilution method, resulted high, reaching 180 kg ha-1 of nitrogen fixed in the biennium. The nitrogen balance method underestimated the nitrogen fixation compared to the isotopic dilution. Very low differences between inoculated and uninoculated sweetvetch were due to a presence of resident rhizobia in the soil. This result outlines the need of evaluating where inoculation is necessary or useless

I Vandali: isolazionismo integralista o logica imprenditoriale? Riflessioni sul Mediterraneo di V-VI secolo

The paper aims to focus some of the main features of the economic management of the Vandal Kingdom, from Africa to Sardinia. By beginning from the awareness of the modern historians to reconsider the Vandals peculiarities, and the interpretation of the ancient sources not damaged by a compromised historical perspective, the paper tries to enlight the business implications of the political economy pursued by the Vandals, from their aggressive maritime policy to the role of coinage and products like the African Red Slip Wares and the amphorae in their trade system.Il contributo affronta alcune tra le principali peculiarità della gestione economica e commerciale del Regno Vandalo, dalle sue prime forme di dominio in Africa fino alle sue più importanti testimonianze in Sardegna. Partendo dalla consapevolezza, da parte della storiografia contemporanea, di aver rivalutato le potenzialità e le caratteristiche dei Vandali, secondo un’ottica non inficiata dalla parzialità delle fonti storiche antiche, si cerca di porre l’accento sui connotati imprenditoriali dell’economia del regno vandalo, dalla sua politica marittima al cospicuo flusso commerciale connotato dalla circolazione di prodotti quali le ceramiche sigillate e le anfore, fino all’ampia diffusione della circolazione monetaria

Il castrum di Sant’Antioco (Carbonia-Iglesias). Riflessione alla luce di alcuni documenti

Nell’ambito degli studi sull’archeologia bizantina in Sardegna il castrum di Sant’Antioco risente di una complessiva man­canza di dati, storici e archeologici. A parte le informazioni scaturite dagli studi effettuati da Vittorio Angius e dal rilievo del Della Marmora nel XIX secolo, si sa ben poco sulla struttura difensiva antiochese, demolita nel 1927 per far spazio all’attuale Campo Sportivo della città di Sant’Antioco. I questo lavoro si intende fornire nuovi spunti di riflessione riguardo alla planimetria del com­plesso, tramite l’analisi comparata di alcuni esemplari cartografici custoditi presso l’Archivio di Stato di Cagliari ed aventi come soggetto il castrum ed il territorio ad esso limitrofo.About Byzantine archaeology in Sardinia the Sant’Antioco’s castrum reflects a total lack of data, both historical and ar­chaeologycal. Apart from the informations revealed by studies conducted by Vittorio Angius and designed by Della Marmora in the XIX century, little is known about antiochese defensive structure, demolished in 1927 to make way for the current Field Sports of Sant’Antioco’s village. This article gives new insights regarding the layout of the complex, through comparative analysis of some cartographic specimens kept at the State Archives of Cagliari which represents the castrum and nearer territories.   

Nodule-associated microbiome diversity in wild populations of Sulla coronaria reveals clues on the relative importance of culturable rhizobial symbionts and co-infecting endophytes

Abstract The culturable bacteria from root nodules of Sulla coronaria growing in spontaneous conditions in Sardinia were characterized. This plant's peculiarity is to represent a legume still found in both wild and cropped statuses. We tested whether culturable bacteria would differ from those commonly isolated from its field-cropped varieties, to date exclusively represented by Rhizobium sullae. 63 isolates from 60 surface-sterilized nodules were analyzed by ARDRA and 16S rDNA sequencing. The official nitrogen-fixing symbiont Rhizobium sullae was found only in 25 nodules out of 60. The remaining nodules did not yield culturable rhizobia but a number of different endophytic genera including Pseudomonas sp. (17 nodules), Microbacterium sp. (15 nodules), Pantoea agglomerans (5 nodules). The situation appears therefore a hybrid between what is commonly observed in other Mediterranean legumes occurring only in wild status (featuring non-culturable rhizobia and arrays of culturable endophytes within nodules), as opposed to cropped legumes (endowed with fully culturable rhizobia and minimal endophytic occurrence). These findings, within a species bridging the ecology between native and cropped conditions, suggest insights on the relative importance of endophytic co-occupancy vs. true N-fixing symbiont culturability within nodules. The latter trait thus appears to accompany the domestication path of plants with a main trade-off of renouncing to interactions with a diversity of endophytic co-invaders; the relationships with those being critical in the non-cropped status. In fact, endophytes are known to promote plant growth in harsh conditions, which can be particularly stressful in the Mediterranean due to drought, highly calcareous soils, and pathogens outbreaks

Studio dell’associazione tra infezione da HPV e tumori extra-cervicali nella popolazione del Nord Sardegna: aspetti epidemiologici, isto-patologici, molecolari e di Sanità Pubblica

More than 100 types of human papillomaviruses (HPVs) have been identified and classified as high- or low-risk according to their oncogenic potential. The mechanism by which HPV leads to malignant transformation is likely mediated by2 viral oncogenes, E6 and E7, which are associated with uncontrolled cellular growth. About4.5% of cancers are attributable to HPV infection with 640,000 casesglobally.Increasing evidence suggest a correlation between HPV-infection and anogenital cancer (anal, vulvar, vaginal, penile), headneck cancer (pharynx, throat, palate, nose) and, furthermore, prostate, bladder and breast cancer.Anal and penile cancers are a relative rare diseases in the general population, however, an increasing trends was reported during last decades in more developed countries. Based on this background, the aim of the present study was to assess: - prevalence and distribution of HPV infection in anal and penile cancers - diagnostic and prognostic role of p16 and E6 transcript, as surrogate markers of HPV infections. An observational, retrospective mono-center study was carried out in North Sardinia, between 2002- 2018. Epidemiological and clinical variables were collected to assess their potential prognostic role. The results obtained confirmed the etiological role of HPV in penile and anal cancer (28.1% and 79%, respectively) with a predominance of HPV-16 genotype. Our study supports the adoption of vaccination strategies in both women and men to prevent HPV related diseases and risk of recurrence in the high risk population. Further studies are needed to better clarify the prognostic role of HPV/p16 status

Impacts of climate change on grapevine: the use of crop model WinStics to estimate potential impacts on grapevine(<i>Vitis vinifera</i> L.) in Sardinia scale

The vine has been extensively studied in the context of climate change studies. In this study an analysis of the potential impacts of climate change on grapevine (Vitis vinifera L.) will be presented. Namely predicting the responses of two main Sardinian varieties - Cannonau and Vermentino, in order to ascertain reliable adjustment cultural practices as well to define possible mitigation strategies. The objectives of this research were to evaluate the effects of climate change and grapevine and phenology, at two experimental sites in Sardinia, different for soil, climate conditions. To achieve these main objectives, the approach used in this study was: The application and assessment of a coupled climate scenario-crop model method, in which Atmosphere-Ocean General Circulation Models, used to generate future climate scenarios, are integrated into crop models to simulate future crop yields. The analysis of daily meteorological variables for current climatic conditions and climate change projections. These data are used as input variables for crop simulation models in conjunction with soil parameters and agronomic and management information, to simulate the dynamics of plant growth and development. The comparison of the results of these simulations for both current and future climatic conditions. Impacts of climate change are then expressed as changes in crop productivity and phenological phases
