Real-time detection of twitter social events from the user's perspective

2015

Over the last 40 years, automatic solutions to analyze text documents collection have been one of the most attractive challenges in the field of information retrieval. More recently, the focus has moved towards dynamic, distributed environments, where documents are continuously created by the users of a virtual community, i.e., the social network. In the case of Twitter, such documents, called tweets, are usually related to events which involve many people in different parts of the world. In this work we present a system for real-time Twitter data analysis which allows to follow a generic event from the user's point of view. The topic detection algorithm we propose is an improved version of…

Fast Volumetric Reconstruction of Human Body through Superquadrics

2013

This paper describes a technique to reconstruct the volumes of the human body. For this purpose, are introduced mathematical objects able to represent 3d shapes, called super quadrics. These objects are positioned in the space according the captures made by a Microsoft Kinect device and are composed to represent the volumes of the human body. The employment of quaternions provides a relevant speedup for the rotation of the volumes and allows to follow the human movements in real time and reduced computational cost.

Stato, rivoluzione e violenza simbolica. Una lettura à la Bourdieu dell’insorgenza cilena

2023

The essay is part of a book that aims to rediscover and enhance Pierre Bourdieu's contribution to the legal philosophy. Clelia Bartoli's paper takes up the French sociologist's theory of the State outlined during courses held at the College de France in 1989/1990 and 1990/1992. Bourdieu eschewed an intellectual fashion of his time that pushed historians, political scientists, lawyers and sociologists to examine the causes and reasons, evolutions and epilogues of revolutions, at the expense, however, of what is happening on the background: the dull, muffled and repetitive order of things. Bourdieu believed that permanence more than change, what is obvious more than what is eccentric, the ord…

Settore IUS/20 - Filosofia Del DirittoSettore SPS/11 - Sociologia Dei Fenomeni PoliticiSettore SPS/01 - Filosofia PoliticaIl saggio si inserisce in un volume che intende riscoprire e valorizzare il contributo di Pierre Bourdieu alla filosofia del diritto. Lo scritto di Clelia Bartoli riprende soprattutto la teoria dello Stato del sociologo francese delineata durante i corsi tenuti al College de France nel 1989/1990 e nel 1990/1992. Bourdieu ha rifuggito una moda intellettuale a lui coeva che spingeva storici politologi giuristi e sociologi a vagliarne cause e ragioni evoluzioni ed epiloghi delle rivoluzioni a discapito però di quanto accade sul fondale: lo scialbo ovattato e ripetitivo ordine delle cose. Bourdieu riteneva che dovesse stupire e meritare di essere spiegato fosse più la permanenza del mutamento l’ovvio più dell’eccentrico l’ordinario più straordinario. Tuttavia nel corso delle lezioni menzionate afferma che per provare nell’ardua impresa di pensare e comprendere lo Stato sia necessario guardare al momento della sua genesi o alle fasi di crisi come durante le rivoluzioni. È infatti in quei momenti che il potere simbolico di cui lo Stato ha il monopolio non è stabile e si presta ad essere osservato come frutto di un processo anziché nella sua ineluttabilità. Le categorie e l’approccio socioepistemico à la Bourdieu vengono adottate dalla Bartoli per leggere il caso dell’insorgenza cilena del 2019 e l’esordio del processo costituente.

Manuel Vázquez Montalbán y sus heterónimos en la revistra "Triunfo"

2022

The volume collects and analyzes the collaborations of Manuel Vázquez Montalbán in the magazine Triunfo, from the opinion article, to the report, from the short story to the comic strip, focusing on the use of heteronomous words. Following the path of the genre, the style and the narrative perspectives of the different contributions, the fertile osmosis between literary discourse and journalistic discourse is thus verified. The weekly appeared in 1946 in Valencia, playing a role of theater and film information and criticism. Since its transfer to Madrid in 1948, the magazine expanded its interests, inserting articles on domestic and foreign policy, until, in the 1960s, it became the intelle…

Settore L-LIN/05 - Letteratura SpagnolaEl volumen recoge y analiza las colaboraciones de Manuel Vázquez Montalbán en la revista Triunfo desde el artículo de opinión al reportaje del cuento a la historieta centrándose en el uso de heterónomos. Siguiendo el camino del género el estilo y las perspectivas narrativas de las distintas aportaciones se constata así la fecunda ósmosis entre discurso literario y discurso periodístico. El semanario apareció en 1946 en Valencia desempeñando un papel de información y crítica teatral y cinematográfica. Desde su traslado a Madrid en 1948 la revista fue ampliando sus intereses insertando artículos sobre política interior y exterior hasta que en la década de 1960 se convirtió en el referente intelectual de la España antifranquista recogiendo las firmas de los intelectuales más incisivos de izquierda. En 1980 la periodicidad pasó a ser mensual hasta su último número en agosto de 1982. El intelectual catalán comienza a colaborar con Triunfo en 1969 año en el que verá la luz el célebre reportaje de cinco números Crónica sentimental de España y mientras tanto la escritura de Vázquez Montalbán adquiere una fisonomía particular en la que el discurso narrativo e incluso poético se injertan en el tejido informático del periódico. Además acompaña su actividad la creación de múltiples heterónomos con diferentes estilos narrativos y perspectivas. Así después de "Jack el Decorador" creado para la revista Hogares Modernos es precisamente en Triunfo donde aparecen las firmas de “Luis Ávila” "Sixto Cámara" "Manolo V el Empecinado" "Luis Dávila" "Menelao el Aeropagita" "Baronesa D´Orcy”. Mientras tanto la función osmótica entre la escritura del intelectual y el discurso periodístico ligada a la macrotextualidad de la revista cobra cada vez más importancia.

Predicting depression from illness severity in cardiovascular disease patients: self-efficacy beliefs, illness perception, and perceived social suppo…

2014

Background: Many studies have investigated the relationships between cardiovascular diseases and patients' depression; nevertheless, few is still known as regard the impact of illness severity on depression and whether psychosocial variables mediate this association. Purpose: The aim of this study is to investigate the putative mediating role of illness representations, self-efficacy beliefs, and perceived social support on the relationship between illness severity and depression. Methods: A total of 75 consecutive patients with cardiovascular disease (80 % men; mean age=65.44, SD=10.20) were enrolled in an Italian hospital. Illness severity was measured in terms of left ventricular ejectio…
