Ultraviolet imaging of volcanic plumes: A new paradigm in volcanology
2017
Ultraviolet imaging has been applied in volcanology over the last ten years or so. This provides considerably higher temporal and spatial resolution volcanic gas emission rate data than available previously, enabling the volcanology community to investigate a range of far faster plume degassing processes than achievable hitherto. To date, this has covered rapid oscillations in passive degassing through conduits and lava lakes, as well as puffing and explosions, facilitating exciting connections to be made for the first time between previously rather separate sub-disciplines of volcanology. Firstly, there has been corroboration between geophysical and degassing datasets at â1 Hz, expeditin…
Le politiche di contrasto al rischio da maremoto: il caso di Stromboli
2020
This chapter, intending to be part of the reasoning on the perception of risk from extreme natural events, intends to describe the main contents of the National Emergency Plan for volcanic events of national importance on the island of Stromboli (ME) prepared in 2015 by the Department for the Civil Protection (DPC). The volcanic island of Stromboli is in fact largely exposed to the risk associated with the activities of the volcano of the same name, especially that of the tsunami. The effusive activity of the Stromboli in fact causes a marked instability of the slope known as Sciara del Fuoco which can induce, as happened at the end of 2002, a tsunami. The contribution, starting from a desc…
Rapid sensing of volcanic SO₂ fluxes using a dual ultraviolet camera system: new techniques and measurements at Southern Italian volcanoes
2012
Volatiles carry crucial information on pre- to sin-eruptive processes at active volcanoes. Measurements of gas emission rates (crater plumes, fumaroles, diffuse soil degassing) therefore improve our understanding of degassing processes and subsurface magmatic and hydrothermal conditions, and contribute to eruption forecasting. Recent technological developments in spectroscopy have allowed, over the last 30 years, the remote sensing of magmatic volatile emissions from quiescent and erupting degassing volcanoes. These data-sets have contributed to discovering cyclic gas flux components due to periodic magma supply and replenishment in magma storage zones, and/or timescales of magma migration …
Volumes of aqueous block copolymers based on poly(propylene oxides) and poly(ethylene oxides) in a large temperature range: A quantitative description
2006
The focus of this paper was on a quantitative comprehension of temperature effect on the volumes of aqueous di-block and triblock copolymers, based on propylene oxide (PO) and ethylene oxide (EO) units. To this purpose, literature data dealing with (EO316PO94 + water) and (EO13PO30EO13 + water) mixtures were analyzed. The volume vs. temperature trends were rationalized on the basis of the (unimers + aggregate) equilibrium by taking into account the temperature effect on both the partial molar volumes of the unimeric and the aggregated copolymer as well as the equilibrium constant of micellization. The analysis extended to the expansibility allowed to quantify the contribution for the shift …
Anatomical and electrophysiological study of the vomeronasal circuits: Amygdaloid response to odours and pheromones
2017
Rodents detect information concerning the world around them mainly through two chemosensory systems: the olfactory and the vomeronasal systems. In order to develop an appropriate behavioural response to their environment, these systems exhibit both functional and physiological convergence. Further understanding of the organization and function of the olfactory systems would allow us to comprehend how their information is integrated in the brain. In a first approach we performed a thorough analysis of the connections of key structures involved in the processing of vomeronasal information: the medial (Me) and the posteromedial cortical (PMCo) amygdaloid nucleus. Then, we enquire the populatio…
Representing the Haitian diaspora in Russell Banks’s Continental Drift, from Port-de-Paix to Little Haiti: a celebration of the margins
2021
International audience; Russell Banks’s 1985 novel Continental Drift tells the intertwined stories of Bob Dubois, a white American man who decides to try his luck in Florida, and the Haitian Vanise Dorsinville, who is forced to leave her island with her son and her nephew to flee Jean-Claude Duvalier’s dictatorial presidency. In this paper, I study how, in the chapters dedicated to the Haitian diaspora, Banks chooses to adopt an ex-centric point of view to give a voice to those whose history and culture have largely been ignored by American society and literature. Vanise is a figure of in-betweenness, caught between Haiti and the United States, between land and ocean, and even between life …
La tutela del lavoratore straniero irregolare dopo il decreto n. 130/2020
2022
Lo scritto si propone di indagare i profili di vulnerabilità legati alla posizione di clandestinità dei migranti irregolari ed il duplice ruolo dell’ordinamento giuridico, quale causa della loro stessa vulnerabilità e strumento di tutela. A tal fine, si propone un’analisi degli ultimi interventi in tema di immigrazione, a cui segue un dettagliato esame della più recente giurisprudenza in materia di protezione speciale. L’obiettivo è quello di definire l’ambito di applicazione della “nuova” protezione speciale come ultimo approdo legislativo in grado di fornire un meccanismo residuale di protezione delle vulnerabilità dei lavoratori migranti, laddove il permesso di soggiorno per motivi di la…

Examining the Impact of eWOM-triggered Customer-to-Customer Interactions on Travelers’ Repurchase and Social Media Engagement
2021
Electronic word-of-mouth (eWOM) communication on social media has revolutionized how travelers search for and share information and how they interact with one another digitally. This research examines the effects of eWOM-triggered customer-to-customer (C2C) interactions on travelers’ post-eWOM behaviors (i.e., repurchase and customer engagement) in a cross-cultural context. Drawing upon cognitive dissonance theory, a scenario-based experiment was conducted using a sample of 461 African tourists with recent intracontinental travel experience. Our findings suggest that a customer’s repurchase intention and engagement in social media C2C interactions are significantly influenced when their eWO…
