Current anthropogenic pressures on agro-ecological protected coastal wetlands
2015
Coastal wetlands are areas that suffer from great pressure. Much of it is due to the rapid development of the surrounding artificial landscapes, where socio-economic factors lead to alterations in the nearby environment, affecting the quality of natural and agricultural systems. This work analyses interconnections among landscapes under the hypothesis that urban-artificial impacts could be detected on soils and waters of an agro-ecological protected area, L'Albufera de Valencia Natural Park, located in the vicinity of the City of Valencia, Spain. The methodological framework developed addresses two types of anthropogenic pressure: (1) direct, due to artificialisation of soil covers that cau…
Per gli antichi chiostri. Monache e badesse nella Palermo medievale
2020
Il libro inquadra la storia degli otto monasteri femminili fondati a Palermo tra l’XI e il XIV secolo sul piano sociale, economico e culturale, ricostruendo le vicende fondative, il patrimonio, il profilo di monache e badesse. All’atto della fondazione i monasteri ricevettero beni di diversa entità, concentrati nella città e nel territorio di Palermo, che divennero il principale cespite finanziario. Solo la metà dei monasteri ebbe in dotazione un feudo che forniva i prodotti agro-pastorali indispensabili per il fabbisogno interno. La monacazione era considerata la forma di esistenza più alta e perfetta; inoltre, le doti monastiche erano di gran lunga inferiori a quelle matrimoniali e consen…
Impacts of COVID-19 and pandemic control measures on public transport ridership in European urban areas – The cases of Vienna, Innsbruck, Oslo, and A…
2021
The study uses the case of two regions with small and medium sized cities (Agder in Norway and the greater Innsbruck area in Austria) and two European capitals, Vienna and Oslo, to showcase the impact of the COVID-19 pandemic on public transport ridership in northern and central Europe. The comprehensive timeline of actions taken by governments and public transport providers in Austria and Norway, and their impact on public transport ridership in the first and second waves of the pandemic form the basis of a descriptive study. Comparing the data, a strong negative impact on the public transport patronage in the first wave of the pandemic was found, despite a comparable low number of cases p…
Megacities without Global Functions.
2007
Present urban evolution is characterized by two major phenomena. On the one hand, the number of very large cities, the megacities, increases dramatically, especially in the less developed countries (LDCs). On the other hand, globalization leads to the emergence of cities coordinating complex and global economic activities, the global cities, especially in the more developed countries (MDCs). So, the two phenomena are diverging. A number of megacities do not exhibit any global function.The global performances of megacities are well correlated with their degree of economic development. But it is worth wondering why economic underdevelopment is consistent with urban growth but not with city gl…
Creative Cities in Italy: new scenarios and projects
2012
Reflections on and experimentation with urban creativity as a competitive factor put together in recent years, starting with the works of Florida and Landry, gave rise to further theoretical/operative reflections aimed at providing a greater territorial dimension to the creative city, lessening the rhetorical character and increasing that of the concrete effects on the quality of life. In 2007 my book “Creative City: Dynamics, Innovations, Actions” identified the need for concrete evolution and pointed out the factors that make it possible for urban creativity to become a launch pad for new economies and a creative force for new cities and not simply an attractive force for intellectual res…
From Paris and Beijing to Washington and Brasilia: the grand design of capital cities and the early plans for Quezon City
2014
International audience; Political leaders have always sought to build monumental capitals, with earlier designs influencing those of later cities. The Western design that revolved around a central axis of power became evident in some Asian capitals, although cities in the Chinese cultural realm differed in shape but nonetheless had its own axis of power. This article provides a typology of capital cities and from this perspective it explores the design of the newly created capital of Quezon City in the late 1930s. Quezon City’s design embraced some design ideas from elsewhere, but it remained unique. However, the design was not realized entirely.
Human leptospirosis cases in Palermo Italy. The role of rodents and climate
2018
Many regions of the world are increasingly exposed to leptospirosis due to poverty, global warming and high urban density. Here, we report a molecular survey for pathogenic Leptospira spp. in rodents and two symptomatic human cases of leptospirosis in the city of Palermo, Italy.Four rodent species were captured in six areas of the city, and a molecular analysis for pathogenic Leptospira spp. on DNA from the kidney samples showed a different prevalence of leptospirosis in all the species of rodents. In addition, two human cases that occurred in May and October of 2009 in the city were also reported. A 67-year-old woman recovered after antibiotic treatment, whereas a 71-year-old woman did not…
Predictions for 5.023 TeV Pb + Pb collisions at the CERN Large Hadron Collider
2016
We compute predictions for various low-transverse-momentum bulk observables in √sNN = 5.023 TeV Pb+Pb collisions at the CERN Large Hadron Collider (LHC) from the event-by-event next-to-leading-order perturbative-QCD + saturation + viscous hydrodynamics (“EKRT”) model. In particular, we consider the centrality dependence of charged hadron multiplicity, flow coefficients of the azimuth-angle asymmetries, and correlations of event-plane angles. The centrality dependencies of the studied observables are predicted to be very similar to those at 2.76 TeV, and the magnitudes of the flow coefficients and event-plane angle correlations are predicted to be close to those at 2.76 TeV. The flow coeffic…
C4 plant isotopic composition (delta13C) evidence for urban CO2 pollution in the city of Cotonou, Benin (West Africa).
2006
9 pages; International audience; The carbon isotopic composition (delta13C) of plants can reveal the isotopic carbon content of the atmosphere in which they develop. The delta13C values of air and plants depend on the amount of atmospheric fossil fuel CO2, which is chiefly emitted in urban areas. A new indicator of CO2 pollution is tested using the delta13C variation in a C4 grass: Eleusine indica. A range of about 4 per thousand delta units was observed at different sites in Cotonou, the largest city in the Republic of Benin. The highest delta13C values, from -12 per thousand to -14 per thousand, were found in low traffic zones; low delta13C values, from -14 per thousand to -16 per thousan…
Rotavirus Genotypes in Sewage Treatment Plants and in Children Hospitalized with Acute Diarrhea in Italy in 2010 and 2011
2014
ABSTRACT Although the molecular surveillance network RotaNet-Italy provides useful nationwide data on rotaviruses causing severe acute gastroenteritis in children in Italy, scarce information is available on rotavirus circulation in the general Italian population, including adults with mild or asymptomatic infection. We investigated the genotypes of rotaviruses present in urban wastewaters and compared them with those of viral strains from clinical pediatric cases. During 2010 and 2011, 285 sewage samples from 4 Italian cities were tested by reverse transcription-PCRs (RT-PCRs) specific for rotavirus VP7 and VP4 genes. Rotavirus was detected in 172 (60.4%) samples, 26 of which contained mul…
