Ocean acidification affects fish spawning but not paternity at CO2 seeps

2016

Fish exhibit impaired sensory function and altered behaviour at levels of ocean acidification expected to occur owing to anthropogenic carbon dioxide emissions during this century. We provide the first evidence of the effects of ocean acidification on reproductive behaviour of fish in the wild. Satellite and sneaker male ocellated wrasse (Symphodus ocellatus) compete to fertilize eggs guarded by dominant nesting males. Key mating behaviours such as dominant male courtship and nest defence did not differ between sites with ambient versus elevated CO2 concentrations. Dominant males did, however, experience significantly lower rates of pair spawning at elevated CO2 levels. Despite the higher r…

Structure and function of the vacuolar Ccc1/VIT1 family of iron transporters and its regulation in fungi

2020

Iron is an essential micronutrient for most living beings since it participates as a redox active cofactor in many biological processes including cellular respiration, lipid biosynthesis, DNA replication and repair, and ribosome biogenesis and recycling. However, when present in excess, iron can participate in Fenton reactions and generate reactive oxygen species that damage cells at the level of proteins, lipids and nucleic acids. Organisms have developed different molecular strategies to protect themselves against the harmful effects of high concentrations of iron. In the case of fungi and plants, detoxification mainly occurs by importing cytosolic iron into the vacuole through the Ccc1/V…

Il Paradigma della Città Fluida

2013

Nella recente crisi globale i poderosi flussi di capitali finanziari, sociali e relazionali che hanno alimentato la riqualificazione urbana nel corso degli ultimi quindici anni non sono più disponibili ad essere intercettati in maniera indiscriminata così come è stato possibile fino a qualche anno fa. Nell'era della crisi strutturale le città più dinamiche non sono più quelle in grado di attrarre progetti urbani iconici ed investitori spinti dal mercato immobiliare o dalla redditività delle attività ricreative, ma quelle città che, a partire dalle loro profonde e diversificate risorse culturali, saranno capaci di attuare una vera e propria “metamorfosi” per usarle come base per la creazione…

In current global crisis the strong flows of financial social and relational capitals that powered urban regeneration over the last fifteen years are no longer available to be tapped in an indiscriminate manner as was the case until just a few years ago. The most dynamic cities in the future will no longer be those that are able to attract urban projects and investors driven by the real estate market or leisure-based development but the cities that have deep and different cultural resources and that are able to use them as the basis for creating new urban cultures and for generating new economic values. Revitalising waterfront is no longer easy opportunity for long-term investments or for using the financial capital gains of corporation or hedge funds but a more creative-driven port city has to provide precious opportunities for real development – not only quantitative but more and more qualitative – that is able to produce effects in both the domain of collective assets and that of private capitals.Settore ICAR/21 - Urbanistica

Usi pubblici e politici di Dante Alighieri

2022

The commemorations of Dante Alighieri ‘s 700th death anniversary saw in 2021 a ‘national’ and even a ‘nationalist ‘ Dante cropping up once again in the Italian public discourse. This article summarises the history of the public and political uses of the poet of the Divina Commedia: from the end of the 18th century, when his modern cult was born, to the Risorgimento, from the First World War to Fascism, up to the more recent ‘pop’ Dante.

In occasione delle celebrazioni per il settecentenario della sua morte in Italia è stato riproposto un Dante “nazionale” e “nazionalista”. In questo articolo si ripercorre la storia degli usi pubblici e politici del poeta della Commedia: dalla fine del Settecento quando nasce il suo culto moderno al Risorgimento dalla Prima guerra mondiale al Fascismo fino agli anni più recenti del Dante “pop”.Settore L-FIL-LET/10 - Letteratura ItalianaSettore L-FIL-LET/11 - Letteratura Italiana Contemporanea

La dimensione tecnologica del museo: forme, tecniche, "identità mutanti" tra storia e contemporaneità

2005

Nella cultura contemporanea il tema della conservazione dell’eredità storica, della rappresentazione e della trasmissibilità dell’arte è argomento ampiamente dibattuto. La forza culturale del museo, detentore dell’eredità, può essere interpretata secondo diverse traiettorie di forme. La memoria intende esprimersi sulle origini e sul significato della "macchina museale" attraverso l’analisi critica dell’oggetto, sia esso contenitore, palco di rappresentazione o scena interattiva. Sonda i processi di comunicazione relativamente alla forma architettonica, alla funzione ed alla fruizione del prodotto espositivo. Tenendo conto delle diverse scuole di pensiero sulla spettacolarizzazione dell’arte…

In present days the storical heritage the transmission of art and its performance is very important argument of debate. Its representation is the building museum in many different forms. The building museum of art is the most important place for exsposition of masterpieces instead the museum of architecture exhibits the works through projects and patterns. Today museum reconstructs the human perception of space using new technologies. The same thing happens for the museum of science and technique where the visitor gets involved in scientific representation. Therefore museum can be a place of study and scientific research. It can be either memory of past times or place of contemporaneity. This study expresses origin and meaning of building museum through the critical analysis of architectonic forms technological aims and the proper use of the exspositive space.Settore ICAR/12 - Tecnologia Dell'Architettura

L’uso tradizionale del legno in Sicilia

2017

Fin dall’antichità, il legno è stato utilizzato per produrre oltre che energia, materiale per la costruzione di edifici e di oggeti che servivano per la vita quotidiana. Ma il legno è stato utilizzato anche come materia prima per la scultura e per i manufati artistici. Anche in Sicilia sono numerosi gli edifici storici (o parti di esso) in legno, mez - zi di trasporto (carri o navi), opere d’arte dipinte su legno, sculture religiose e strumenti musicali che sono arrivati ai giorni nostri e che dimostrano le abilità e la padronanza di tecniche nelle civiltà del passato. Indubbiamente il legno era nella cultura rurale una risorsa essenziale ed un capitale per l’economia dei piccoli laboratori…

Adolescent transport and unintentional injuries: a systematic analysis using the Global Burden of Disease Study 2019

2022

Correction to Lancet Public Health 2022; 7: e657-69. Lancet Public Health. 2022 Dec;7(12):e992. doi: 10.1016/S2468-2667(22)00294-8. PMID: 36462522. Background: Globally, transport and unintentional injuries persist as leading preventable causes of mortality and morbidity for adolescents. We sought to report comprehensive trends in injury-related mortality and morbidity for adolescents aged 10-24 years during the past three decades. Methods: Using the Global Burden of Disease, Injuries, and Risk Factors 2019 Study, we analysed mortality and disability-adjusted life-years (DALYs) attributed to transport and unintentional injuries for adolescents in 204 countries. Burden is reported in absolut…

Trends in the prevalence of asthma and allergic rhinitis in Italy between 1991 and 2010

2012

The prevalence of asthma increased worldwide until the 1990s, but since then there has been no clear temporal pattern. The present study aimed to assess time trends in the prevalence of current asthma, asthma-like symptoms and allergic rhinitis in Italian adults from 1990 to 2010. The same screening questionnaire was administered by mail or phone to random samples of the general population (age 20-44 yrs) in Italy, in the frame of three multicentre studies: the European Community Respiratory Health Survey (ECRHS) (1991-1993; n=6,031); the Italian Study on Asthma in Young Adults (ISAYA) (1998-2000; n=18,873); and the Gene Environment Interactions in Respiratory Diseases (GEIRD) study (2007-2…
