A colloquio con Gaspare Spatuzza. Un racconto di vita, una storia di stragi
2016
C’è un periodo della storia del nostro Paese che avremmo potuto raccontare come fosse il momento si sono aperte le porte dell’inferno. Questo sono state le stragi di mafia dei primi anni Novanta, con i lutti e le distruzioni provocate dall’attacco allo Stato da parte di Cosa Nostra e di altri poteri occulti. Si tratta di vicende narrate e indagate in tanti modi. La novità di questo studio è la strada, il percorso attraverso cui il lettore può esplorare la quotidianità di Cosa Nostra, quell’inferno dei vivi che – dopo aver tentato di fare guerra allo Stato – ancora oggi brucia vite umane, tiene sotto giogo interi quartieri, città, economie nazionali e internazionali. Il libro è il racconto d…
Towards a fuzzy-linguistic based social network sentiment-expression system
2015
Liking allows users of Social Networks, blogs and online magazines to express their support of posts and artifacts by a simple click. Such function is very popular but lacks semantic power, and some platforms have augmented it by allowing to choose a pictographic depiction corresponding to a feeling. What is gained in depth is lost in simplicity, and the wide acceptance liking has enjoyed did not carried to the sentiment version. We outline a sentiment-expression hybrid system based on textual analysis and linguistic fuzzy Markov chains overcoming the intrinsic limitations of liking without burdening the user with complex choices.
What drives the helpfulness of online reviews? A deep learning study of sentiment analysis, pictorial content and reviewer expertise for mature desti…

Los destinos turísticos se ven cada vez más afectados por la información relacionada con los viajes que se comparte a través de las redes sociales. Basándose en teorías de proceso dual sobre cómo los individuos procesan la información, este estudio examina el papel de las rutas de procesamiento de información central y periférica en la formación de las percepciones de los consumidores sobre la utilidad de las reseñas en línea de destinos maduros. Llevamos a cabo un proceso de dos pasos para abordar la utilidad percibida del contenido generado por el usuario, un análisis de sentimiento utilizando técnicas avanzadas de aprendizaje automático (aprendizaje profundo) y un análisis de regresión. …
Percorsi di riflessione etica sul valore umano ed educativo della sofferenza. Alcune definizioni operative
2011
La concezione personalistica cristiana permette una corretta visione antropologi- ca ed etica che fonda le riflessioni delle scienze umane (sociologia, psicologia, pedagogia, scienze della comunicazione) che vogliono analizzare le situazioni in cui versano il paziente oncologico terminale, i suoi familiari e coloro che si occupano dell’attività di assistenza clinico-sanitaria, sociale e volontaria. Se- condo tale concezione, la “persona” è un’unità inscindibile di corpo, psiche e spirito, di sesso maschile e femminile, destinata a una dimensione trascendente e ultraterrena dell’essere. La persona ammalata di cancro, in questa visione, non può essere ridotta a mero agglomerato psicofisico, a…
When a new technological product launching fails: A multi-method approach of facial recognition and E-WOM sentiment analysis
2018
Abstract The dual aim of this research is, firstly, to analyze the physiological and unconscious emotional response of consumers to a new technological product and, secondly, link this emotional response to consumer conscious verbal reports of positive and negative product perceptions. In order to do this, biometrics and self-reported measures of emotional response are combined. On the one hand, a neuromarketing experiment based on the facial recognition of emotions of 10 subjects, when physical attributes and economic information of a technological product are exposed, shows the prevalence of the ambivalent emotion of surprise. On the other hand, a nethnographic qualitative approach of sen…
Analysis and Comparison of Deep Learning Networks for Supporting Sentiment Mining in Text Corpora
2020
In this paper, we tackle the problem of the irony and sarcasm detection for the Italian language to contribute to the enrichment of the sentiment analysis field. We analyze and compare five deep-learning systems. Results show the high suitability of such systems to face the problem by achieving 93% of F1-Score in the best case. Furthermore, we briefly analyze the model architectures in order to choose the best compromise between performances and complexity.
Increasing the Inference and Learning Speed of Tsetlin Machines with Clause Indexing
2020
The Tsetlin Machine (TM) is a machine learning algorithm founded on the classical Tsetlin Automaton (TA) and game theory. It further leverages frequent pattern mining and resource allocation principles to extract common patterns in the data, rather than relying on minimizing output error, which is prone to overfitting. Unlike the intertwined nature of pattern representation in neural networks, a TM decomposes problems into self-contained patterns, represented as conjunctive clauses. The clause outputs, in turn, are combined into a classification decision through summation and thresholding, akin to a logistic regression function, however, with binary weights and a unit step output function. …
Pharmacological genome demethylation increases radiosensitivity of head and neck squamous carcinoma cells
2011
Aberrant inactivation of tumor suppressor genes by promoter hypermethylation has been recognized as a crucial step of tumor development and is related to aggressiveness and therapy resistance. To identify potential novel treatment strategies, we evaluated pharmacological genome demethylation for the increase of irradiation treatment effectiveness in head and neck squamous cell carcinoma (HNSCC) in this in vitro study. HNSCC cells were cultured with 2 different concentrations of 5-azacytidine (5-Aza) for 72 h, followed by a single fraction irradiation with 4 or 50 Gy, respectively. To show successful genome demethylation, the methylation status of the tumor suppressor gene hic1 (hypermethyla…
Prensa, populismo y resistencia. "Crónica sentimental de Esapaña" de Manuel Vázquez Montalbán en la revista Triunfo
2020
In the fall of 1969, Manuel Vázquez Montalbán published five reports entitled Crónica sentimental de España, where he analyzes everyday life to reflect the sentimental evolution of Spaniards from the 1940s to the 1960s and highlights the mechanisms by which popular culture forges the collective imagination, while the Francoism makes it a transmitter of moral conduct norms within a program of populist propaganda. The aim of this study is to go through the narrative construction of the journalistic text and its focus on the populist discourse which becomes a proposal of resistance. En el otoño de 1969, Manuel Vázquez Montalbán publica cinco reportajes bajo el título Crónica sentimental de Esp…
Educación sentimental, humorismo y nuevos modelos femeninos: Plaerdemavida («Tirant»), Triola («Platir») y otras doncellas confidentes en libros de c…
2020
En el presente artículo se analiza un estereotipo femenino de los libros de caballerías, el de las doncellas confidentes, desde la perspectiva de la función didáctica que desempeñan en el ámbito sentimental y erótico respecto a sus amigas. Enfocando algunas figuras concretas, como Plaerdemavida en Tirant lo Blanc y Triola en Platir, se considera el valor del humorismo en la asunción de un papel educativo que posibilita el establecimiento, por parte de estas mujeres, de un juego con el concepto de amor y de sexualidad. Dicho juego participa en la creación de un paradigma de conducta femenina que se escapa de las normas convencionales para abrazar también costumbres potencialmente transgresiv…
