Knowledge exchange through science diplomacy to assist disaster risk reduction
2021
Abstract This paper analyses science diplomacy efforts to reduce disaster risks and proposes establishing national knowledge exchange centers (KECs) to help individual states adhere to their Sendai Framework goals. KECs are considered to be interconnected globally and work together to promote resilience efforts by facilitating sharing of information and strategies in risk monitoring, assessment, and ultimately reduction across the globe. KECs can provide high-quality scientific evidence for informed decisionmaking along with a component related to disaster science media to ensure that appropriate knowledge reaches a variety of people who need it in different forms tailored for them. KECs ca…

Robert Foulke, The Sea Voyage Narrative, Routledge, New York and London, 1997, pp. 244, ISBN 0-415-93894-5. The Sea Voyage Narrative consente al lettore di immergersi nell'affascinante mondo della letteratura di mare. Robert Foulke, fine conoscitore dell'ambiente marino, mette in luce la complessità e l'aspetto proteiforme della sea literature, che non può definirsi come un vero e proprio genere letterario, ma soltanto come un'ampia categoria descrittiva. Il testo è suddiviso in sei capitoli, ciascuno dei quali analizza aspetti connessi alle esperienze di viaggi per mare in relazione con elementi narratologici e tematici di capolavori della sea literature.
Mechanics and self-organization in tissue development
2021
Self-organization is an all-important feature of living systems that provides the means to achieve specialization and functionality at distinct spatio-temporal scales. Herein, we review this concept by addressing the packing organization of cells, the sorting/compartmentalization phenomenon of cell populations, and the propagation of organizing cues at the tissue level through traveling waves. We elaborate on how different theoretical models and tools from Topology, Physics, and Dynamical Systems have improved the understanding of self-organization by shedding light on the role played by mechanics as a driver of morphogenesis. Altogether, by providing a historical perspective, we show how i…
Store Brands in Tourist Services
2016
A current trend in retailing is the use of a brand extension strategy by supermarkets and hypermarkets, which enhances the store brand’s presence in a growing number of product categories. In the travel services domain, research on store brand extension is scarce. This research paper aims to fill in a gap on brand extension of current traditional store brands to travel services. Based on a sample of 608 individuals, our findings suggest that the likelihood of choosing a travel service offered by a local retailer (hypermarket/supermarket) is directly and positively conditioned by (1) the individual’s overall attitude towards store brands, (2) customer perception of the retailer’s trustworthi…
Automating the Parameter Selection in VRP: An Off-line Parameter Tuning Tool Comparison
2014
Vehicle route optimization is an important application of combinatorial optimization. Therefore, a variety of methods has been proposed to solve different challenging vehicle routing problems. An important step in adopting these methods to solve real-life problems is to find appropriate parameters for the routing algorithms. In this chapter, we show how this task can be automated using parameter tuning by presenting a set of comparative experiments on seven state-of-the-art tuning methods. We analyze the suitability of these methods in configuring routing algorithms, and give the first critical comparison of automated parameter tuners in vehicle routing. Our experimental results show that t…
Existence of a traveling wave solution in a free interface problem with fractional order kinetics
2021
Abstract In this paper we consider a system of two reaction-diffusion equations that models diffusional-thermal combustion with stepwise ignition-temperature kinetics and fractional reaction order 0 α 1 . We turn the free interface problem into a scalar free boundary problem coupled with an integral equation. The main intermediary step is to reduce the scalar problem to the study of a non-Lipschitz vector field in dimension 2. The latter is treated by qualitative topological methods based on the Poincare-Bendixson Theorem. The phase portrait is determined and the existence of a stable manifold at the origin is proved. A significant result is that the settling time to reach the origin is fin…
Generation of travelling sine-Gordon breathers in noisy long Josephson junctions
2022
The generation of travelling sine-Gordon breathers is achieved through the nonlinear supratransmission effect in a magnetically driven long Josephson junction, in the presence of losses, a current bias, and a thermal noise source. We demonstrate how to exclusively induce breather modes by means of controlled magnetic pulses. A nonmonotonic behavior of the breather-only generation probability is observed as a function of the noise intensity. An experimental protocol providing evidence of the Josephson breather's existence is proposed.
Gioielli siciliani nelle testimonianze dei viaggiatori inglesi in Sicilia tra XVIII e XIX secolo
2020
The attention that is dedicated to the Decorative Arts in the travelers' diaries is much inferior in comparison to that one turned to the archaeology, to the painting or to the sculpture. As far as jewelry is concerned, in particular, the growing admiration for the craftsman's mastery was flanked by the traditional consideration of its splendor as a status symbol and the ancestral conception of precious stones as bearers of particular magical or apotropaic powers. It is, however, natural that the quotations of jewels in the diaries of the Grand Tour are in small numbers compared, for example, to those relating to archaeological ruins, and their collection is the result of targeted research …
La grandeur & la beauté - Le Arti Decorative siciliane nei diari dei viaggiatori francesi tra XVII e XIX secolo
2021
This volume constitutes the second stage of a research project which, through a detailed study of the accounts of foreign travellers who arrived in Sicily between the 17th and 19th centuries, has identified descriptions of the Sicilian decorative arts seen during their itineraries. After having published the results of the research on the diaries of English travellers in the volume Beauty and Splendour - Le Arti Decorative siciliane nei diari dei viaggiatori inglesi tra XVIII e XIX secolo, the results of the scientific research on the diaries of French travellers are presented here.

2019
The essay analyses the testimonies of foreign travellers on the church of Santa Caterina al Cassaro in Palermo between the 18th and 19th centuries, contextualising them with the cultural and historical-artistic panorama of the time.
