Dinamiche dell'estorsione e risposte di contrasto fra diritto e società
2016
Il volume raccoglie i contributi interdisciplinari sul fenomeno estorsivo che, nel contesto del progetto europeo GLODERS (Global Dinamics of Extortion Racket Systems), sono stati elaborati dall’unità di ricerca presso il Dipartimento di Giurisprudenza dell’Università di Palermo. Sulla base della rilevazione di dati giudiziari relativi alla diffusione dell’estorsione in alcune realtà territoriali in Sicilia e in Calabria, l’indagine affronta la realtà empirica, i profili giuridici dell’attività di contrasto, coniugando un approccio sociologico quali-quantitativo, i modelli simulativi e le tecniche computer-assistite, l'analisi giuridica, per delineare innovativi interventi di politica crimin…
On the interplay between cosmological shock waves and their environment
2017
Cosmological shock waves are tracers of the thermal history of the structures in the Universe. They play a crucial role in redistributing the energy within the cosmic structures and are also amongst the main ingredients of galaxy and galaxy cluster formation. Understanding this important function requires a proper description of the interplay between shocks and the different environments where they can be found. In this paper, an Adaptive Mesh Refinement (AMR) Eulerian cosmological simulation is analysed by means of a shock-finding algorithm that allows to generate shock wave maps. Based on the population of dark matter halos and on the distribution of density contrast in the simulation, we…

Assimilation and Contrast in Spontaneous Comparisons: Heterogeneous Effects of Standard Extremity in Facial Evaluations
2020
Judgments we make about others often depend on the standards we use as comparisons. Investigations into the outcomes of these comparisons and potential moderators have often been limited to single dimensions and preselected standards. The current work instead uses multiple evaluative facial dimensions and a multitude of comparisons. A series of 4 experiments ('N' = 665) attempted to detect contrast from extreme (Study 1) and assimilation to moderate standards in within (Studies 2 and 3) and between-subjects designs (Study 4). Results showed inconsistent evidence for both comparison effects and significant heterogeneity across the evaluative dimensions that were sampled. An additional 5 stud…
The relationship between positive and negative affect in the Positive and Negative Affect Schedule
2002
Abstract The Positive and Negative Affect Schedule (PANAS; Watson, Clark, & Tellegen, 1988 ) is one of the most widely used affect scales. Nevertheless, the relation between its two scales, positive affect (PA) and negative affect (NA), is still controversial. Previous results that suggest independence between NA and PA were limited to manifest variables. In this study, the relation between PA and NA for both state and trait instructions was analyzed by means of structural equation modeling. Two hundred ninety-two participants responded to the PANAS at three occasions of measurement. No association was found between trait PA and NA, but significant negative correlations between state PA and…
MultiSlice human organ extraction based on GVF
2008
Segmentation techniques based on active contours algorithm are widely used in medical imaging. Unfortunately, they require a lot of parameters to be used and this can rep- resent an issue for those physicians with not much informatics skills. This paper proposes a software tool which allows to segment multiple slice can differ organ extraction setting a small number of parameters. Moreover, the tool offers the functionality to perform a multiple segmentation the same time, so that an entire volume composed by hundreds slices can be segmented.
Locally weighted spatio-temporal minimum contrast for Log-Gaussian Cox Processes
2022
We propose a local version of the spatio-temporal log-Gaussian Cox processes (LGCPs) employing the Local Indicators of Spatio-Temporal Association (LISTA) functions into the minimum contrast procedure to obtain space as well as time-varying parameters. We resort to the joint minimum contrast method fitting method to estimate the set of second-order parameters for the class of spatio-temporal LGCPs. This approach has the advantage of being usable in the case of both separable and non-separable parametric specifications of the correlation function of the underlying Gaussian Random Field (GRF).
SPEECH AND SILENCE IN CICERO'S FINAL DAYS
2014
Composed in spring of 46 BC, Cicero's Brutus emphasizes oratorical silence, in stark contrast with the prominence of the speech act found in the Pro Marcello and first Philippic. Yet in the face of those difficult times and amidst the silence that such times engender, Cicero ironically finds his voice. This paper will demonstrate Cicero's acute awareness, in his final days, of the need to employ his rediscovered voice in light of eloquence's changed role in Rome's new political climate.
