The Trasversale Sicula. Themes and action research projects in sensitive Mediterranean areas

2022

There are many sensitive territories located in disadvantaged areas of the Mediterranean where depopulation has been a significant consequence of their economic and demographic decline. This has led to the gradual flight of young people and the disappearance of certain essential services. The conservation of resources is a topic of growing interest in Europe. It is necessary to rethink a new vision concerning the territory of small towns. Within this framework, this action research project aims to define a new collective sensibility, full of resources and history, throughout the territory of the Trasversale Sicula. The narrative of a new imaginary of the Sicilian hinterland is the foundatio…

I traffici illeciti nel Mediterraneo. Persone, stupefacenti, tabacco. Report Spagna

2019

Il Report analizza il sistema penale spagnolo attraverso la disciplina di contrasto a quattro diversi traffici: favoreggiamento dell'immigrazione clandestina, tratta di esseri umani, traffico di stupefacenti e contrabbando di sigarette. Il Report è parte di una più vasta ricerca ("The New Era of Smuggling in the Mediterranean Sea", NESMeS) volta ad analizzare i suddetti traffici all'interno del Mediterraneo, con specifico riferimento ai seguenti Paesi: Germania, Grecia, Italia, Portogallo e Spagna. Oltre al Report spagnolo, la ricerca NESMeS ha realizzato altri contributi: uno per ciascun Paese, un report criminologico e un libro finale ("I traffici illeciti nel Mediterraneo. Persone, stupe…

Fenêtres sur cases : la fenêtre comme figure réflexive dans quelques bandes dessinées contemporaines

2020

Cet article décrit comment la bande dessinée peut proposer un nouveau paradigme de réflexivité : la fenêtre prend la place du miroir et remplace une réflexivité du sujet par une réflexivité du code. Les fenêtres dans les bandes dessinées sont les équivalents des cases et elles structurent la planche comme des façades d’immeubles. Plusieurs dessinateurs (de Will Eisner à Pascal Rabaté) utilisent le potentiel spectaculaire de la fenêtre pour montrer explicitement le fonctionnement propre de leurs oeuvres et inventent de nouvelles formes d’albums qui vont déconstruire ou reconstruire la représentation.

The Beginning and End of Parental Responsibility — Finnish Parents’ Views

2012

INTRODUCTIONParental responsibility is a topic much discussed in present-day society. In these discussions the concept of parental responsibility appears self-explanatory, and it is often seen as the common denominator in dealing with child behaviour and educational issues, particularly in problem-centred discussions. Generally, responsibility seems to be one of the key concepts in policy-making and public debate about the lives of children and parents (Such & Walker, 2004).A theoretical model of present-day life that deals with parenting but also relates to parental responsibility is the theory of individualization (Giddens 1991, 1992). Individualization is a term used by Beck and Beck-Ger…

Tuberculation in spatangoid fascioles: Delineating plausible homologies

1998

The existing definition of spatangoid fascioles as a narrow band of minute tubercles (miliaries) is inadequate. One reason is that many intermediates between the presence of indisputable fascioles and their total absence are known. Although fascioles are widely used in the classification of spatangoids, diversity of fasciole tuberculation has largely been ignored. We examine fascioles in about 100 spatangoid species, focusing on the earliest manifestations of fascioles (both developmentally and phylogenetically) and on their variable tuberculation. Qualitative observations are complemented by quantitative analyses (ANOVA and PCA) of 21 species. Three types of fascioles are defined according…

Sparse multipath channels: Modelling, analysis, and simulation

2013

A sparse multipath channel is characterized by a small number of randomly distributed scatterers. This study proposes a methodology for the modelling of sparse multipath channels. The new methodology is then used to develop a sparse narrowband multipath channel model by applying the sum-of-cisoids (SOC) principle. The statistical properties of the presented sparse SOC multipath channel model are studied. Analytical expressions are derived for the mean value, variance, autocorrelation function (ACF) and cross-correlation function (CCF) of the complex channel gain, as well as for the probability density function (PDF) of the envelope. Our study shows that mobile radio channels behave in spars…

Filter multiplexing by use of spatial Code Division Multiple Access approach.

2003

The increasing popularity of optical communication has also brought a demand for a broader bandwidth. The trend, naturally, was to implement methods from traditional electronic communication. One of the most effective traditional methods is Code Division Multiple Access. In this research, we suggest the use of this approach for spatial coding applied to images. The approach is to multiplex several filters into one plane while keeping their mutual orthogonality. It is shown that if the filters are limited by their bandwidth, the output of all the filters can be sampled in the original image resolution and fully recovered through an all-optical setup. The theoretical analysis of such a setup …
