Closer Investigation of the Kinetics and Mechanism of Spirovinylcyclopropyl Oxindole Reaction with 3Σ–g-O2 by Topological Approaches and Unraveling t…
2021
In this investigation at the MN15L/Def2-TZVP level of theory, we present computational evidence indicating that the reaction of 3Σ-g-O2 with spirovinylcyclopropyl oxindole (2) leads to a product called spiro-1,2-dioxolane (2) in its singlet state; this reaction occurs via a stepwise mechanism and its rate-determining step is catalyzed by iodine radicals, which promotes opening of the three-membered ring under dark conditions. The conversion of 2 to 1-benzylindoline-2,3-dione (3) and 2-vinyloxirane (4) takes place via a concerted and slightly asynchronous reaction. Both electron localization function and AIM topological analysis reveal that the step associated with the attack of the 3Σ-g-O2 …
Terrorismo yihadista: un protocolo de evaluación del riesgo de radicalización y de comisión de atentados
2019
El objetivo principal de la tesis es elaborar un protocolo de evaluación integral del riesgo de radicalización y de comisión de atentados yihadistas. Para alcanzar este propósito, la investigación se estructuró en dos partes diferenciadas. La primera consistió en una revisión bibliográfica de la literatura internacional sobre el fenómeno del terrorismo yihadista. Se realizó una fundamentación teórica sobre los factores de riesgo de radicalización y de comisión de atentados, así como de los protocolos teóricos y empíricos existentes al respecto. La segunda acogió una investigación empírica original. Se confeccionó una extensa base de datos con todos los atentados de índole yihadista perpetra…
The FE-Meshless multiscale approach applied to masonry structures
2015
Heterogeneous structures have an overall response that is strongly dependent on the inelastic events developing at the local level. In these structures, the most relevant kinematical and mechanical phenomena take place at a scale which is small if compared to the dimensions of the entire structure. In literature, a mesoscopic and a macroscopic scales of interest are distinguished, directly linked to as many theoretical approaches. The mesoscopic approach [1] considers materials and their interfaces individually, but many difficulties arise in the mesh creation and a fine discretization of the structure is needed, which leads to prohibitive computational costs. The macroscopic approach consi…
"Io ho ragione; tu sei morto!" Su terrorismo e radicalizzazione
2018
Il contributo analizza il radicalismo come presupposto ideologico del terrorismo, proponendo un'analisi concettuale e criminologica delle diverse possibili forme di radicalizzazione e dei suoi rapporti con la violenza terroristica. Vi si analizzano altresì possibilità e limiti di de-radicalizzazione e contro-radicalizzazione quali strategie di contrasto al terrorismo alternative rispetto alla coercizione penale. The paper focuses on radicalism as the ideological background of terrorism, by putting forth a conceptual and criminological analysis of the different forms radicalization can take as well as of its relationships with terrorist violence. The paper also analyzes de-radicalization and…
Dagens Rødhette i en flerkulturell kontekst – mulighet for en ny identitet?
2013
The starting point for this article is the tendency in recent Norwegian children’s and Ya fiction to thematize cultural encounters in an increasingly multicultural and globalized world. The picturebook Little Miss Eye Flap ( Skylappjenta , 2009) written by the Pakistani-Norwegian author and actor Iram Haq and illustrated by Endre Skandfer, presents a modern version of traditional folktales such as Little Red Riding Hood and Rapunzel . However, the traditional structure of home – away – home gives particular emphasis to the phase of homelessness, not providing any safe return to harmony. This condition of liminal space between cultures is discussed in light of the concepts of reflexive ident…

The castle's Hermitage of Yecla (Region of Murcia) constituted during the 13th to 16th centuries the first parish of the population, hosting a triptych-shaped altarpiece presided over by a tempera painting on wood of Our Lady of Humility or "Virgo Lactans", dated around 1370 and attributed to the painter Barnaba da Modena, which was the titular image of the mentioned temple under the title of Our Lady of the Incarnation, until at the end of the 18th century it changed ownership for the Conception of Our Lady. The table at averages of the eight hundred was placed in an a loft, appropriating it at the beginning of the 20th century by the retired military Pascual Spuche y Lacy, who sold it aro…
Design ed eco-sostenibilità: le fibre vegetali in Sicilia tra tradizione ed innovazione
2012
Il dibattito sulla questione ambientale, sorto tra gli anni ‘60 e ‘70 del secolo scorso, con la formazione delle prime associazioni ambientaliste, ebbe come nodo centrale il rapporto tra economia e ambiente, nella sempre più evidente necessità di preservare la qualità del patrimonio naturale e nella consapevolezza che, essendo le risorse del pianeta tendenzialmente esauribili, dovessero essere rivisti ed equilibrati i modelli di sviluppo. Gli oggetti, secondo la lezione di Bruno Latour, simboleggiano stili di vita che comprendono al loro interno processi comunicativi e riguardano in ogni caso la sfera dell’informazione, dell’interazione, del ricordo e anche del desiderio. L’omologazione del…
Dialogue as a Response to the Psychiatrization of Society? Potentials of the Open Dialogue Approach
2021
In recent decades, the use of psychosocial and psychiatric care systems has increased worldwide. A recent article proposed the concept of psychiatrization as an explanatory framework, describing multiple processes responsible for the spread of psychiatric concepts and forms of treatment. This article aims to explore the potentials of the Open Dialogue (OD) approach for engaging in less psychiatrizing forms of psychosocial support. While OD may not be an all-encompassing solution to de-psychiatrization, this paper refers to previous research showing that OD has the potential to 1) limit the use of neuroleptics, 2), reduce the incidences of mental health problems and 3) decrease the use of ps…
Regularization Preserving Localization of Close Edges
2007
International audience; In this letter, we address the problem of the influence of neighbor edges and their effect on the edge delocalization while extracting a neighbor contour by a derivative approach. The properties to be fulfilled by the regularization operators to minimize or suppress this side effect are deduced, and the best detectors are pointed out. The study is carried out in 1-D for discrete signal. We show that among the derivative filters, one of them can correctly detect our model edges without being influenced by a neighboring transition, whatever their separation distance is and their respective amplitude is. A model of contour and close transitions is presented and used through…
Nuevos enfoques en el estudio de la accesibilidad a los servicios públicos. Un estudio aplicado a los centros que imparten el segundo ciclo de educac…
2020
La Educación Infantil se ha convertido en un elemento estratégico para el desarrollo de muchos países debido a los múltiples beneficios personales, económicos y sociales que reporta. Desde el ámbito de la planificación espacial educativa se busca que todos los alumnos tengan un acceso equitativo a los colegios en términos de calidad y accesibilidad, haciendo un uso eficiente de los mismos. El objetivo general de la tesis consiste en evaluar la accesibilidad locacional y personal de la demanda potencial a la red de centros públicos y concertados que imparten el segundo ciclo de Educación Infantil en la ciudad de Valencia, a fin de establecer propuestas de mejora. Para ello, se hace un diagnó…
