Group-Analytic Family Psychotherapy: A Transcultural Perspective
1997
Group-analytic family psychotherapy is a methodology based on a development of Group-analytic theory. The family is defined as a mental field formed by the symbolic plot of `us' in a double relationship: with the cultural history of the family group on one side, and with external groups on the other. The symbolic plot thus has a tribal characteristic which connects the genealogical trees to the ancestral foundation of the group. In cases of psychotic and borderline patients, Group-analytic family psychotherapy has indicated two types of family: those that are embedded in the past, or families that are cut off from the past. After outlining the circumstances of Italian families, this articl…
Figure della maternità e itinerari dell’attesa negli oggetti del Museo etnografico siciliano Giuseppe Pitrè
2023
Il contributo propone una riflessione sul tema della maternità che lega, come un filo rosso, gli oggetti del Museo etnografico siciliano Giuseppe Pitrè e ne struttura la narrazione. Lo sguardo rivolto alle collezioni e al loro ordinamento restituisce la centralità di una tematica che riflette il senso profondo della cultura che gli oggetti comunicano e svela, attraverso i suoi simboli, i significati contestuali delle sue figure: le madri e i loro corpi, le madrine e i loro ruoli, le levatrici e le loro potenzialità. The contribution proposes a reflection on the theme of motherhood that links the objects of the Sicilian Ethnographic Museum Giuseppe Pitrè as a core idea and a narrative struct…
A simple joint estimation-detection technique for OFDM systems
2005
In this work a simple approach for the joint estimation-detection in a frequency selective severe fading environment of OFDM signals adopting PSK constellations is presented. A linear predictor of suitable order is adopted for the channel estimation in the frequency domain. The predictor coefficients are estimated on the basis of a sample estimation of the autocorrelation of the channel frequency response, aided by a preliminary differential decoding, in a blockwise manner. The detection technique proposed here is based on a simple tree search where a small number of best survivor paths are maintained at each step. Despite the simplicity of above detection approach, the simulation results s…
H�lder continuity of solutions to quasilinear elliptic equations involving measures
1994
We show that the solutionu of the equation $$ - div(|\nabla u|^{p - 2} \nabla u) = \mu $$ is locally β-Holder continuous provided that the measure μ satisfies the condition μ(B(x,r))⩽Mrn − p + α(p − 1) for some α>β. A corresponding result for more general operators is also proven.
Fusayolas de la necrópolis de Olival do Senhor dos Mártires (Alcácer do Sal, Portugal) : tipología, función y simbolismo
2018
La presencia de un conjunto significativo de fusayolas entre los ajuares de la necrópolis de la Edad del Hierro de Olival do Senhor dos Mártires (Alcácer do Sal, Portugal) plantea cuestiones de gran interés sobre los límites entre la función de estos elementos y su significado simbólico y escatológico. En este estudio se abordan esas cuestiones, analizando por un lado las características físicas, tecnológicas y morfológicas de las piezas, y por otro los posibles códigos simbólicos y religiosos que las convierten en elementos integrales del ajuar funerario en distintas comunidades del sur peninsular.
Numerical studies to detect chaotic motion in the full planar averaged three-body problem
2023
AbstractIn this paper, the author deals with a well-known problem of Celestial Mechanics, namely the three-body problem. A numerical analysis has been done in order to prove existence of chaotic motions of the full-averaged problem in particular configurations. Full because all the three bodies have non-negligible masses and averaged because the Hamiltonian describing the system has been averaged with respect to a fast angle. A reduction of degrees of freedom and of the phase-space is performed in order to apply the notion of covering relations and symbolic dynamics.
Statistical physics: Some basic principles of fluctuation and noise theory
1983
Abstract Models have traditionally played a significant role in statistical mechanics. In view of the complexity of the system which statistical mechanics attempt to describe, this is not at all surprising. The study of simplified models has frequently revealed the underlying mathematical structure of many physical questions and in so doing the study of models has contributed directly to a clarification of several paradoxes which beset statistical mechanics. In this paper some of the models which appear to be useful for the discussion of non-equilibrium phenomena are examined in some detail. As usual these models are extremely simplified versions of the actual situations. It is, finally, as…
Social representations of latin american immigrants about immigration, care and elderly caregivers
2013
Ageing in Spain has increased considerably and elderly people often find themselves in a situation of great dependence. Facing this situation, many have had the support of immigrant caregivers from Latin America. This research had the purpose to know the social representations (SR) of these caregivers, living in Valencia (Spain), about immigration, care and elderly care. It involved the participation of 35 immigrants who responded the Word Association Test and a socio-demographic questionnaire. The results revealed that the SR on immigration reflect "nostalgia", care was represented by "help", and care for the elderly by "respect". It is concluded that the SR allow understanding the symboli…
Robust Graph Topology Learning and Application in Stock Market Inference
2019
In many applications, there are multiple interacting entities, generating time series of data over the space. To describe the relation within the set of data, the underlying topology may be used. In many real applications, not only the signal/data of interest is measured in noise, but it is also contaminated with outliers. The proposed method, called RGTL, infers the graph topology from noisy measurements and removes these outliers simultaneously. Here, it is assumed that we have no information about the space graph topology, while we know that graph signal are sampled consecutively in time and thus the graph in time domain is given. The simulation results show that the proposed algorithm h…
Su mortu mortu vs Halloween. Questue infantili in Sardegna
2020
Il contributo indaga il rapporto fra questue infantili tradizionali e Halloween in Sardegna. Dalle ricerche sul campo è emerso che in diversi centri Halloween è subentrato ai giri di raccolta consuetudinari, in altri convive con essi, ma nella maggior parte dei paesi il festival di origine anglosassone non si è ancora diffuso poiché, appunto, sono vitali le questue tradizionali. Si tratta di due manifestazioni rituali diverse, espressione di contesti storici e socioculturali ma anche politico-economici differenti e tuttavia i simboli rituali più noti della “carnevalata americana" – la zucca con la candela accesa, la formula rituale per la richiesta dei doni e la minaccia di ritorsioni per l…
