Drosophila-inspired visual orientation model on the Eye-Ris platform: Experiments on a roving robot
2011
Behavioral experiments on fruit flies had shown that they are attracted by near objects and they prefer front-to-back motion. In this paper a visual orientation model is implemented on the Eye-Ris vision system and tested using a roving platform. Robotic experiments are used to collect statistical data regarding the system behaviour: followed trajectories, dwelling time, distribution of gaze direction and others strictly resembling the biological experimental setup on the flies. The statistical analysis has been performed in different scenarios where the robot faces with different object distribution in the arena. The acquired data has been used to validate the proposed model making a compa…
Effettività delle indagini ed "equità processuale". Il punto su investigazioni scientifiche sulla persona e operazioni sotto copertura
2018
Il contributo, che fa principalmente riferimento alla giurisprudenza della Corte europea, si incentra in una prima parte sul difficile bilanciamento tra gli obiettivi di "equità processuale" e quelli di "effettività delle indagini": ciò, in considerazione di quanto disposto dall'art. 6 Cedu, nonché degli obblighi procedimentali derivanti da diverse norme convenzionali, come gli artt. 2 e 3 Cedu. Una seconda parte del lavoro si riferisce, invece, a due più specifici ambiti, oggetto di un'attenta analisi della Corte di Strasburgo, ossia quelli relativi alla "prova scientifica" e alle "indagini sotto copertura". Il filo conduttore, nel complesso, è la ricerca di un equilibrio nell'attuazione d…

Pesca nelle acque di Paesi terzi e attività “internazionali” di soggetti privati: il caso del Distretto della Pesca e Crescita Blu
2022
Lo scritto affronta il tema della compatibilità dell’attività di cooperazione internazionale portata avanti da soggetti privati, come ad esempio il Distretto della Pesca e Crescita Blu di Mazara del Vallo, con il quadro normativo eurounitario in tema di accordi di pesca con Paesi terzi, prospettando anche un ruolo di garanzia da parte della Regione siciliana, il cui Statuto attribuisce all’amministrazione regionale competenza esclusiva in materia di pesca. The essay addresses the issue of compatibility of international cooperation activities carried out by private entities, such as the District of Fishing and Blue Growth of Mazara del Vallo, with the Community regulatory framework on fishin…
Il problema dell'eutanasia nell'ordinamento multilivello: la prospettiva della tutela dei diritti fondamentali
L'evento della verità in Heidegger
2013
Partendo dall'interpretazione di Ugazio sul tema dell'inizio, l'evento in Heidegger viene connesso con una riflessione sulla negatività e con il riferimento essenziale al farsi presente (Anwesen)
Physiological advantages of dwarfing in surviving extinctions in high-CO2 oceans
2015
Excessive CO 2 in the present-day ocean-atmosphere system is causing ocean acidification, and is likely to cause a severe biodiversity decline in the future, mirroring effects in many past mass extinctions. Fossil records demonstrate that organisms surviving such events were often smaller than those before, a phenomenon called the Lilliput effect. Here, we show that two gastropod species adapted to acidified seawater at shallow-water CO 2 seeps were smaller than those found in normal pH conditions and had higher mass-specific energy consumption but significantly lower whole-animal metabolic energy demand. These physiological changes allowed the animals to maintain calcification and to parti…
Attentional processing biases to threat in schizophrenia: Evidence from a free-viewing task with emotional scenes
2021
Attentional biases to threatening stimuli have been suggested to play a key role in the onset and course of schizophrenia. However, current research has not completely demonstrated this assumption. The aim of this eye-tracking study was to shed light on the underlying psychological mechanisms of schizophrenia by examining the attentional processing of socio-emotional information. Forty-four individuals with schizophrenia and 47 healthy controls were assessed in a 3-s free-viewing task with a social scene (i.e., happy, threatening, or neutral) in competition with a non-social one to determine the effects of emotional information on the different stages of the attentional processing. The loca…
Observing animals and humans : dogs target their gaze to the biological information in natural scenes
2020
Background This study examines how dogs observe images of natural scenes containing living creatures (wild animals, dogs and humans) recorded with eye gaze tracking. Because dogs have had limited exposure to wild animals in their lives, we also consider the natural novelty of the wild animal images for the dogs. Methods The eye gaze of dogs was recorded while they viewed natural images containing dogs, humans, and wild animals. Three categories of images were used: naturalistic landscape images containing single humans or animals, full body images containing a single human or an animal, and full body images containing a pair of humans or animals. The gazing behavior of two dog populations,…
