Naturalistic hotspots along the Itinerarium Rosaliae (CW Sicily, Italy)
2018
The conservation, fruition and management of landscape and natural resources is one of the most important topic of the moment. Here we presented a study on naturalistic hotspots that can be found along the Itinerarium Rosaliae, a naturalistic and religious route in Sicily that crosses three natural reserves and one natural regional park connecting Mount Pellegrino with the Hermitage of Santo Stefano di Quisquina. On the whole 7 semi-natural woods, 13 monumental trees, 8 geosites, and 4 areas of high naturalistic interest were identified. This initiative can be of example for other territories where human and natural heritage can be connected for an organic network of fruition.
Shift in Tuna Catches due to Ocean Warming.
2017
Ocean warming is already affecting global fisheries with an increasing dominance of catches of warmer water species at higher latitudes and lower catches of tropical and subtropical species in the tropics. Tuna distributions are highly conditioned by sea temperature, for this reason and their worldwide distribution, their populations may be a good indicator of the effect of climate change on global fisheries. This study shows the shift of tuna catches in subtropical latitudes on a global scale. From 1965 to 2011, the percentage of tropical tuna in longliner catches exhibited a significantly increasing trend in a study area that included subtropical regions of the Atlantic and western Pacifi…
Self-organized dynamics in spatially structured populations
2001
Self-organization and pattern formation represent the emergence of order in temporal and spatial processes. Self-organization in population ecology is gaining attention due to the recent advances concerning temporal fluctuations in the population size of dispersal-linked subunits. We shall report that spatially structured models of population renewal promote the emergence of a complex power law order in spatial population dynamics. We analyse a variety of population models showing that self-organization can be identified as a temporal match in population dynamics among local units, and how the synchrony changes in time. Our theoretical results are concordant with analyses of population data…
Topographic Independent Component Analysis reveals random scrambling of orientation in visual space
2017
Neurons at primary visual cortex (V1) in humans and other species are edge filters organized in orientation maps. In these maps, neurons with similar orientation preference are clustered together in iso-orientation domains. These maps have two fundamental properties: (1) retinotopy, i.e. correspondence between displacements at the image space and displacements at the cortical surface, and (2) a trade-off between good coverage of the visual field with all orientations and continuity of iso-orientation domains in the cortical space. There is an active debate on the origin of these locally continuous maps. While most of the existing descriptions take purely geometric/mechanistic approaches whi…
An attraction-based cellular automaton model for generating spatiotemporal population maps in urban areas
2015
We develop a cellular automaton (CA) model to produce spatiotemporal population maps that estimate population distributions in an urban area during a random working day. The resulting population maps are at 50 m and 5 minutes spatiotemporal resolution, showing clearly how the distribution of population varies throughout a 24-hour period. The maps indicate that some areas of the city, which are sparsely populated during the night, can be densely populated during the day. The developed CA model assumes that the population transition trends follow dynamics and propagation patterns similar to a contagious disease. Thus, our model designed to change the states of each grid cell (stable or dynami…
Mafia Methods, Extortion Dynamics and Social Responses
2016
This chapter is devoted to exploring both the empirical results and the policy proposals produced by the GLODERS project. Based on 631 cases of extortions, the Sicily and Calabria extortion database represents a relevant achievement in the field of the research on extortion racket and it is one of the main results of the GLODERS project. Gathering a great amount of information, our empirical analysis revealed the existence of several differences in the extortive conducts carried on within these two regions, which are presented. Moreover, the chapter introduces the legislation related to the crime of extortion. Social and legal responses to the phenomenon are then discussed.
Spatio-Temporal Spread Pattern of COVID-19 in Italy
2021
This paper investigates the spatio-temporal spread pattern of COVID-19 in Italy, during the first wave of infections, from February to October 2020. Disease mappings of the virus infections by using the Besag–York–Mollié model and some spatio-temporal extensions are provided. This modeling framework, which includes a temporal component, allows the studying of the time evolution of the spread pattern among the 107 Italian provinces. The focus is on the effect of citizens’ mobility patterns, represented here by the three distinct phases of the Italian virus first wave, identified by the Italian government, also characterized by the lockdown period. Results show the effectiveness of the lockdo…
Educatio siglo XXI : revista de la Facultad de Educación
2015
La presencialidad obligatoria en Educación Superior y el creciente número de estudiantes con compromisos familiares justifican la necesidad de conocer las opiniones del alumnado con respecto a la conciliación estudiantil-familiar en el contexto universitario. Se adopta una metodología cualitativa mediante narrativas. Participan de la investigación 27 estudiantes de la Universitat de València y 46 de la Universidad de Alicante, del Grado en Maestro de Educación Primaria. Los resultados evidencian limitaciones, dificultades y demandas ante las nuevas exigencias metodológicas y evaluativas, si se tienen cargas familiares. Se concluye con propuestas académicas, legislativas y de implementación …
Vision metrology and Structure from Motion for archaeological heritage 3D reconstruction: A Case Study of various Roman mosaics
2017
<p class="Abstract">Vision metrology and computer vision can be successfully used for archaeological heritage 3D reconstruction in very high precision 3D measurement projects. Of those archaeological objects requiring very accurate measurements (&lt;1 mm), ancient mosaics comprise some of the most important. The aim of this paper is to assess the photogrammetric/computer vision approach in a vision metrology context as part of a 3D mosaics survey. In order to evaluate the optimal photogrammetric/computer vision workflow in this work, three different surveys were performed on three mosaics of different sizes and locations. Two of these are stored at the <em>Antonino Salinas&l…
Democracia, argumentación e ideologías jurídicas | Democracy, Argumentation and Legal Ideologies
2016
RESUMEN. Este trabajo analiza la relacion de la democracia y la argumentacion juridica desde diversas perspectivas. En primer lugar, desde un punto de vista externo, que apunta al fundamento politico y moral de las corrientes argumentativas dentro de la Filosofia del Derecho. En segundo lugar, aborda esta relacion desde un punto de vista interno, analizando el papel del principio democratico en el marco de un modelo general de racionalidad argumentativa. Y, por ultimo, pretende hacer una caracterizacion de las teorias/ideologias juridicas en el contexto de la democracia constitucional. ABSTRACT. This paper analyzes from varied perspectives the relation between democracy and legal argumentat…
