Hide and Seek. Roads, Lookouts and Directional Visibility Cones in Central Anatolia
In Cappadocia (central Turkey), routes that were only of a secondary importance during the Roman age acquired a new relevance starting from the end of the 7th century. In this framework, to what extent did the archaeological evidence match the picture recalled by the written sources? To address this question, the relationship between movement and visibility was considered and viewshed analyses were conducted from targeted and strategic spots set along the routes considered. This allowed to better understand the role and the different functions of those axes crossing Cappadocia, and to evaluate the Byzantine/Arab military strategies in central Anatolia
L’asilo politico nelle relazioni franco-italiane. I signori nessuno e l’impossibile status dell’opposizione italiana all’estero (1920-1986)
Ce travail de recherche plonge ses racines dans l’analyse de la typologie d’accueil particulière dont ont bénéficié les exilés politiques italiens des années 1970-1980. La problématique à la base de cette thèse se propose de comprendre si la politique française d’accueil de ces années-là peut être considérée comme un fait nouveau ou si, au contraire, elle est à interpréter comme un geste dont les racines remontent à une plus longue histoire : celle de l’asile politique. Nous analyserons selon une perspective de longue période le rapport existant entre les institutions politiques et administratives des Etats et les groupes sociaux. Avec cette analyse, nous voudrions contribuer à reconstruire l’origine des pratiques, des instruments et finalement des conceptions politiques et juridiques que la France et l’Italie ont appliquées au groupe d’émigrés politiques italiens en France. La thèse se compose des deux parties, (avant et après deuxième guerre mondiale). Nous allons d’abord reconstruire la naissance des principes constitutifs de l’asile politique en Europe tout au long du XIX siècle. Nous allons donc analyser la gestion étatique de la présence en France d’une grande partie de l’opposition italienne pendant les années Vingt et Trente, d’abord selon une perspective bilatérale, et ensuite internationale. Dans la deuxième partie du travail nous allons reconstruire les changements du cadre juridique de référence au lendemain de la deuxième guerre mondiale. Nous allons ensuite analyser la façon dont les Etats ont géré la présence en France de l’opposition extra-parlementaire italienne des années soixante-dix, d’abord d’un point de vue bilatéral, et ensuite multilatéral.This thesis analyses how Italy and France dealt with handling and controlling Italian opposition in France. Chosen time interval elapses from 1920 to 1986. During these years two political opponents’ migratory waves were monitored by the two nations: anti fascist emigration and several revolutionary left wing former militants of the Seventies emigration. The thesis analysis by a long period perspective how French and Italian institutions confronted with such a phenomenon, particularly considering the issue of juridical status conferred to Italian opponents abroad.
During analysed period Italy and France operated in a precise diplomatic context characterised by the multiplication of bilateral and multilateral interrelations that progressively became more and more crucial with regards to the states’ management of political emigration. Carried out analysis will underline continuity and breaches of this relation.
Thesis first part analyses Italian Reign period from 1870 to end of Second World War. Introduction will mark the origin of asylum key principles that precedes chosen historical period but is fundamental to analyse the juridical frame of France and Italy future steps. First and Second Chapter focus on years between 1920 and 1940, with particular attention to political emigration handling by a bilateral (Chap. 1) and by a multilateral perspective (Chap. 2). Thesis Second part focuses on Republican Italy. The Introduction retraces juridical frame partial changes and focuses on asylum debate in the Italian Constituent. Analysis of political emigration handling will be carried out both from a bilateral (Chap. 3) and multilateral perspective (Chap. 4)
DUE O TRE COSE A CUI NON CREDO. A MARGINE DI UN PARRICIDIO COMPIUTO DI ROBERTO FINELLI
I very appreciate the analysis conducted by Roberto Finelli on Marx’s textes, but I have some doubts regarding the total horizon that Finelli promises: the accomplished “abstraction” (as “dematerialisation”) that Marx had prophesied. In this paper I try to explain why I don’t think that Marx was a prophet; I don’t think that the world (and the capitalistic production) has become immaterial; I don’t think that the main problem is a “catastrophe of emotion”
Evaluación de un novedoso prototipo diseñado para el apoyo y la sujeción cefálica en pacientes con asistencia respiratoria mecánica
Objetivos: 1) Fabricar un prototipo de almohada para apoyo y sujeción cefálica para pacientes críticos con asistencia respiratoria mecánica, 2) comparar su eficacia con la de los métodos alternativos de apoyo y sujeción, 3) monitorizar la formación de escaras en contacto con el prototipo, 4) relevar la opinión del personal de enfermería. Diseño: Ensayo clínico con distribución aleatoria. Ámbito: Unidad de Cuidados Intensivos de un hospital privado.Pacientes: 52 hombres y mujeres con asistencia respiratoria mecánica, de entre 31 y 91 años de edad, reunidos en dos grupos: uno de 23 pacientes, que usaron métodos alternativos, y otro de 29 que utilizaron el prototipo.Intervenciones: Se registró la posición de la cabeza en los 52 pacientes por un lapso de entre 1 y 7 días corridos, 3 veces por día; y el desplazamiento del tubo endotraqueal se registró una vez por día. Catorce enfermeros/as respondieron un cuestionario.Variables de interés principales: Posición de la cabeza y desplazamiento del tubo endotraqueal.Resultados: La cabeza se mantuvo centrada en el 56,9% (métodos alterna-tivos) y en el 87,3% (prototipo) (p 0,9). Doce de los 14 enfermeros/as encuestados prefirieron el prototipo a los métodos alternativos. Conclusiones: El prototipo resultó significativamente más eficaz que los métodos alternativos para mantener la cabeza centrada, mientras que no así para prevenir el desplazamiento del tubo endotraqueal. La mayoría del personal de enfermería prefirió el prototipo a los métodos alternativos.Fil: Turchetto, Elsio S.. Hospital Italiano de Mendoza; ArgentinaFil: Navarro Arce, Graciela.

Influence of distributary channels on sediment and organic matter supply in event-dominated coastal margins: the Po prodelta as a study case
From November 2008 through May 2009, the Po river (Italy) experienced several floods exceeding 5000 m<sup>3</sup> s<sup>−1</sup>. This long series of events ended with a large flood in early May 2009 (~8000 m<sup>3</sup> s<sup>−1</sup>). An event-response sampling was carried out in the Po prodelta in April–May 2009 to characterize the preservation of this series of floods in the sediment record and to describe the event-supply and deposition of riverborne particulate material during the May 2009 flood. The water sampling was carried out early in the event under conditions of moderate river flow (~5000 m<sup>3</sup> s<sup>−1</sup>) and 24 h later during the peak discharge (~8000 m<sup>3</sup> s<sup>−1</sup>). Sediment cores were collected in the prodelta before and after the peak flood. At each station, profiles of conductivity, transmittance, and fluorescence were acquired. Surface and bottom waters were sampled to collect sediments in suspension. In addition, a few days before the May 2009 event, suspended sediments were collected at Pontelagoscuro gauging station, ~90 km upstream from the coast. Biogeochemical compositions and sedimentological characteristics of suspended and sediment samples were investigated using bulk and biomarker analyses. Furthermore, <sup>7</sup>Be and radiographs were used to analyze the internal stratigraphy of sediment cores. <br><br> During moderate flow, the water column did not show evidence of plume penetration. Stations re-occupied 24 h later exhibited marked physical and biogeochemical changes during the peak flood. However, the concentration of terrestrially-derived material in surface waters was still less than expected. These results suggested that, since material enters the Adriatic as buoyancy-driven flow with a reduced transport capacity, settling and flocculation processes result in trapping a significant fraction of land-derived material in shallow sediments and/or within distributary channels. <br><br> Although numerous discharge peaks occurred from November 2008 through April 2009 (4000–6000 m<sup>3</sup> s<sup>−1</sup>), sediment cores collected in late April 2009 showed lack of event-strata preservation and reduced <sup>7</sup>Be penetrations. This suggested that only a small fraction of the sediment supply during ordinary events reaches the deepest region of the prodelta (12–20 m water depth). As a result, these event-strata have a thickness not sufficient to be preserved in the sediment record because of post-depositional processes that destroy the flood signal. <br><br> Stations in the northern and central prodelta were re-occupied after the peak of the May 2009 flood. Based on <sup>7</sup>Be and radiographs, we estimated event layers of 17 and 6 cm thickness, respectively. Selective trapping of coarse material occurred in the central prodelta likely because of the geomorphologic setting of the central outlet characterized by an estuary-like mouth. Despite these settling processes, lignin-based parameters indicated that the composition of the terrigenous OC was fairly homogenous throughout the network of channels and between size-fractions
Analysis on the relation between ESG rating and the historical prices time series through a phase space reconstruction algorithm
LAUREA MAGISTRALENegli ultimi anni il mondo finanziario ha iniziato a prestare attenzione al rating ESG,
acronimo di Environmental, Social and Governance. Questa tesi si propone di indagare
se i titoli ESG possono essere considerati un asset class a se stante. Abbiamo scelto di
analizzare il mercato mondiale, americano, europeo, emergente, italiano e giapponese,
quindi per ognuno di essi abbiamo selezionato due indici, uno ESG e uno più generale, e
abbiamo studiato le serie storiche corrispondenti.
A differenza di quanto fatto nella letteratura esistente, in questo lavoro per effettuare
l’analisi abbiamo utilizzato l’algoritmo di phase space reconstruction proposto da Li et
al. [26] per generare una rete dalle serie storiche e poi abbiamo confrontato l’indice di
complessità sviluppato da Cao et al. [8] delle serie storiche ESG e di quelle non ESG.
Questo aspetto è discusso in dettaglio nel secondo capitolo, dove si spiegherà che quando si
considerano le serie storiche nella loro interezza, quelle ESG hanno una critical embedding
dimension più piccola rispetto a quelle non ESG, da cui consegue che gli indici ESG hanno
una maggiore complessità. Tuttavia, analizzando le serie storiche con la stessa lunghezza
(cioè troncando le serie storiche non ESG in modo da avere lo stesso numero di osservazioni
per ogni coppia di indici), il risultato è diverso e le serie storiche ESG sono quelle con
minore complessità.
Nel terzo capitolo, l’argomento è il comportamento delle serie storiche ESG e non-ESG
durante un periodo di stress nei mercati. Analizziamo la crisi finanziaria di Covid-19,
scoprendo che il valore più alto di complessità si riscontra in generale nel periodo successivo
alla crisi, mentre la complessità più bassa si osserva durante la crisi stessa. Inoltre, in
questo periodo, la complessità delle serie storiche ESG risulta essere superiore a quella
delle serie storiche non ESG.
Infine, nell’ultimo capitolo, utilizziamo finestre temporali mobili per studiare come la
critical embedding dimension e la complessità delle serie storiche cambiano nel tempo.
Per piccole finestre temporali mobili, le serie storiche ESG tendono ad avere una maggiore
complessità e una componente casuale più marcata, mentre quelle non ESG hanno una
critical embedding dimension media più piccola per grandi finestre temporali mobili.In the last few years, the financial world has started to pay attention to the ESG rating,
which stands for Environmental, Social and Governance. This thesis aims to investigate
if ESG stocks can be considered a different asset class with different characteristics than
general stocks. We chose to analyze the World, the American, the European, the Emerg-
ing, the Italian and the Japanese markets, so for each of them we selected two indexes,
one ESG and one more general, and we studied the corresponding time series.
Unlike what was done in the existing literature, in this work to carry out the analysis we
used the phase space reconstruction algorithm proposed by Li et al. [26] to generate a
network from the time series and then we compare the Complexity index developed by
Cao et al. [8] of the ESG time series and of the non-ESG ones. This is discussed in detail
in Section 2.2 where it will be explain that when we consider the time series with their full
length the ESG ones have a smaller critical embedding dimension than non-ESG ones,
from which follows that ESG indexes have a greater complexity. However, analyzing time
series with the same length (i.e. truncating the non-ESG time series in order to have the
same number of observation for every couple of indexes), the outcome is different and
ESG time series are the ones with lower complexity.
In Section 2.3, the topic is the behavior of ESG and non-ESG time series in a stressed
market. We analyze the Covid-19 financial crisis, discovering that the highest value of
complexity is found in general in the period after the crisis, while the lowest complexity
is seen in the crisis period. Moreover, during the financial crisis analyzed, the complexity
of the ESG time series turns out to be higher than the complexity of the non-ESG ones.
Finally, in Section 2.4, we use sliding time windows to study how the critical embedding
dimension and complexity of the time series change over time. For small sliding time
windows, ESG time series tend to have a greater complexity and random component,
while non-ESG ones have a smaller average critical embedding dimension for large sliding
time windows
