Masonry structures: A proposal of analytical generation of fragility functions for tsunami impact – Application to the Mediterranean coasts

2021

Abstract Evaluation of tsunami vulnerability of coastal buildings is gaining high interest in recent years in the areas with high tsunami hazard. Fragility evaluation is a fundamental step to obtain a quantitative estimation of the probability of building damage and in order to define possible strategies for risk mitigation. Several empirical fragility curves are available for masonry structures. However, an empirical fragility curve is generally based on field surveys after tsunami events, not always available. Conversely, analytical fragility curves are based on prediction approaches. In this paper, a proposal for the evaluation of analytical fragility curves for masonry structures typica…

Vulnerabilità, consenso, responsabilità: alcuni casi di grave sfruttamento lavorativo e tratta delle donne migranti in Italia

2017

A partire dalla definizione di sfruttamento e dalla problematizzazione dell'idea di libertà contrattuale e di consenso, il contributo analizza alcuni casi di grave sfruttamento lavorativo e di tratta ai danni delle donne migranti nell'ambito del settore domestico e di quello agricolo. I dati e le interviste qualitative raccolte sul campo confermano quindi le premesse teoriche (e normative) che avevano ricostruito la vulnerabilità in termini di mancanza di alternative percorribili e la tratta come abuso della posizione di vulnerabilità così definita.

Seabird influence on ecological processes in coastal marine ecosystems: An overlooked role? A critical review

2021

Abstract Seabirds are vital, but overlooked, components of coastal marine ecosystems and may connect the marine and terrestrial environment at a global scale, significantly contributing to inter-habitat connectivity and the provision of multiple ecosystem services. Although the ecological and functional role of birds in terrestrial areas, islands in particular, has been deeply studied since the last century, the same does not hold true for coastal marine areas. Given the importance of coastal areas for seabirds worldwide and, at the same time, the high vulnerability of both, looking into the role of seabirds in influencing the ecosystem functioning in coastal areas is needed nowadays. Here,…

Taphonomical peculiarities and formation conditions of Baltic Devonian vertebrate fossil assemblages

2013

Devona mugurkaulnieku atrodņu tafonomiskais raksturojums un veidošanās apstākļi dienvidaustrumu Baltijā Pirmo reizi paleontoloģisko pētījumu vēsturē Baltijā ir veikta detalizēta Živetas, Franas un Famenas mugurkaulnieku atrodņu tafonomisko īpašību analīze, izmantojot mūsdienu metodiku. Savā starpā ir salīdzinātas vidējā un augšējā devona oriktocenozes Latvijas teritorijā, bet Baltijas (Galvenā devona lauka) fosiliju atrodnes ir salīdzinātas ar sakopojumiem Dienvidu Timanā. Ir secināts, ka, neskatoties uz tafonomisko pazīmju atšķirībām, Franas un Famenas klastiskās slāņkopas, kā arī vidus- un augšdevona mugurkaulnieku sakopojumu veidošanās mehānismi Baltijā ir bijuši visai līdzīgi. Ir noteik…

Adaptation to host inVibrio vulnificus, a zoonotic pathogen that causes septicemia in fish and humans

2019

Vibrio vulnificus is a siderophilic pathogen spreading due to global warming. The zoonotic strains constitute a clonal-complex related to fish farms that are distributed worldwide. In this study, we applied a transcriptomic and single gene approach and discover that the zoonotic strains bypassed the iron requirement of the species thanks to the acquisition of two iron-regulated outer membrane proteins (IROMPs) involved in resistance to fish innate immunity. Both proteins have been acquired by horizontal gene transfer and are contributing to the successful spreading of this clonal-complex. We have also discovered that the zoonotic strains express a virulent phenotype in the blood of its main…

Managing information security risks during new technology adoption

2012

Author's version of an article in the journal: Computers and Security. Also available from the publisher at: http://dx.doi.org/10.1016/j.cose.2012.09.001 In the present study, we draw on previous system dynamics research on operational transition and change of vulnerability to investigate the role of incident response capability in controlling the severity of incidents during the adoption of new technology. Toward this end, we build a system dynamics model using the Norwegian Oil and Gas Industry as the context. The Norwegian Oil and Gas Industry has started to adopt new information communication technology to connect its offshore platforms, onshore control centers, and suppliers. In oil co…

Vulnerability maps pollution to hydrocarbon and urban waste pollution in seawater intrusion areas

2004

De acuerdo con un proyecto nacional promovido por el Grupo Nacional Italiano para la Protección contra Riesgos Hidrogeológicos han sido publicados los mapas de vulnerabilidad (1:50.000) de parte del Territorio Italiano, particularmente algunos mapas de Sicilia: Montes Iblei, Moadonie, Sicani y el Monte Etna. Estos mapas se han vuelto documentos públicos para el manejo local del agua subterránea. Algunos fenómenos muy peligrosos han sido reportados en algunas áreas de Sicilia. Intervenciones antrópicas han creado basureros de residuos tóxicos sobre áreas vulnerables. Esta investigación explica las ventajas del uso de mapas de vulnerabilidad en estudio de tipos peligrosos de contaminación par…

Phylogeny and life cycle of the zoonotic pathogen Vibrio vulnificus

2020

Vibrio vulnificus is a zoonotic pathogen able to cause diseases in humans and fish that occasionally result in sepsis and death. Most reviews about this pathogen (including those related to its ecology) are clearly biased towards its role as a human pathogen, emphasizing its relationship with oysters as its main reservoir, the role of the known virulence factors as well as the clinic and the epidemiology of the human disease. This review tries to give to the reader a wider vision of the biology of this pathogen covering aspects related to its phylogeny and evolution and filling the gaps in our understanding of the general strategies that V. vulnificus uses to survive outside and inside its …

Evaluation of genotypic and phenotypic methods to distinguish clinical from environmental Vibrio vulnificus strains.

2009

ABSTRACT Vibrio vulnificus is a heterogeneous bacterial species that comprises virulent and avirulent strains from environmental and clinical sources that have been grouped into three biotypes. To validate the typing methods proposed to distinguish clinical from environmental isolates, we performed phenotypic (API 20E, API 20NE, and BIOLOG tests) and genetic (ribotyping and DNA polymorphism at several loci) studies with a large strain collection representing different biotypes, origins, and host ranges. No phenotypic method was useful for biotyping or grouping strains with regard to the origin of an isolate, and only the BIOLOG system was reliable for identifying the strains at the species …
