Theodor Wiesengrund-Adorno: interpretación históriconatural
2015
La tesis trata de construir una concepción de la filosofía actual como interpretación históriconatural a partir de la obra de Theodor Wiesengrund-Adorno. Se centra en las conferencias „Die Aktualität der Philosophie“ (1931), „Die Idee der Naturgeschichte“(1932) y las dos versiones de su escrito de habilitación sobre los libros sobre Kierkegaard. Es la primera investigación tanto en español como en alemán que trabaja partes del original escrito de habilitación – inédito hasta ahora – de Adorno Konstruktion des Ästhetischen in Kierkegaards Philosophie comparándolo con la versión corregida y publicada del mismo: Kierkegaard. Konstruktion des Ästhetischen. Tras una exposición de la concepción d…
Darwinism and the Origin of Life
2012
Abstract Historically, ideas on the origins of life have been mingled with evolutionary explanations. Darwin avoided discussing the origin of the very first species in public although he acknowledged the possibility that life originated by natural causes. Some of his followers adopted this materialistic position and advocated some sort of spontaneous generation in the distant past. Nevertheless, Pasteur’s experiments were a major obstacle for scientific acceptance of the sudden emergence of life. The scientific study of the origin of life, established in the 1920s, required abandoning the idea of a unique chance event and considering a view of life emerging as the result of a long evolution…

Approccio computazionale per la certificazione di strutture aeronautiche in materiale composito
Il processo di certificazione di strutture in materiale composito utilizzate per componenti aero-strutturali è principalmente analitico supportato dall’evidenza dei test a livello di coupon, elementi, sub-componenti, componenti e full-scale. Il processo di certificazione stabilisce che specifiche metodologie di test e particolari controlli dei processi vengano applicati per la qualifica del materiale e dei vari componenti, per verificare la conformità del progetto ai requisiti richiesti. Le procedure (basate su tecniche statistiche) per la caratterizzazione di materiali compositi, comportano l’impegno di una quantità molto grande di risorse ad ogni livello: il criterio di base infatti vuole…
Psilocybin as an Inducer of Ego Death and Similar Experiences of Religious Provenance
2016
Abstract The purpose of this chapter is to provide an overview of the impact of hallucinogenic psilocybin on religious-type emotionality related to ego disintegration. Psilocybin as a typical hallucinogen evokes alternations of visual perception (enhances a development of pseudo-hallucinations, phantom visual perception, or hypnagogic experiences). These visual phenomena may be inspiring and are claimed to enhance aesthetic appreciation. Additionally the hallucinogen induces transient impairment of cognitive functions and psychological regression comparable to the signs of ego blurring and dissociative phenomena. The psilocybin effects, initially euphoric, may become emotionally perceived a…
Flows of information and meaning: a vocabulary approach to integrated thinking and reporting
2020
PurposeIntegrated reporting (IR) is increasingly becoming a practice useful not only for accountability but also for managerial purposes because of its potential role as a signifying practice for integrated thinking (IT). In this perspective, this paper aims to explore which of the objects that are represented in integrated reports provide materiality and common understanding to the concept of IT for its effective implementation within organizations.Design/methodology/approachThis paper is based on a vocabulary approach for interpreting the texts of integrated reports as systems of words that are able to provide meaning for a common understanding of the concept of IT. In particular, by focu…
Why do Helvétius' writings matter? Rousseau's Notes sur De l'esprit
2016
International audience; De l’esprit was read and commented on by Rousseau, Diderot, and Voltaire, in 1758. So was De l’homme when it appeared posthumously in 1773. We will go into this series of books, marginalia, and refutations, to address the question: what exactly was widely discussed between the three authors during the 1750s? Is it ‘materialism’? Our first point is to interpret the potential distortions, re-workings or re-appropriations in Rousseau’s marginalia, known as Notes sur De l’esprit, especially here about the so-called theory of passive judgement. We will then see that there certainly is, in the discussion between Rousseau and Helvétius, a real opposition on the question of…

Structure–Property Relationships in Bionanocomposites for Pipe Extrusion Applications
2021
In this work, bionanocomposites based on different biodegradable polymers and two types of nanofillers, namely a nanosized calcium carbonate and an organomodified nanoclay, were produced through melt extrusion, with the aim to evaluate the possible applications of these materials as a potential alternative to traditional fossil fuel-derived polyolefins, for the production of irrigation pipes. The rheological behavior of the formulated systems was thoroughly evaluated by exploiting different flow regimes, and the obtained results indicated a remarkable effect of the introduced nanofillers on the low-frequency rheological response, especially in nanoclay-based bionanocomposites. Conversely, t…
