Selective oxidation of aromatic alcohols in the presence of C3N4 photocatalysts derived from the polycondensation of melamine, cyanuric and barbituri…
2021
AbstractA set of C3N4 samples has been prepared by using melamine, cyanuric acid and barbituric acid as the precursors. The materials were subjected both to physical and chemical characterization and were used as photocatalysts for the selective oxidation of aromatic alcohols in water suspension under UV and visible irradiation. The photoactivity of the materials versus the partial oxidation of four substituted benzyl alcohols was investigated. The type and position of the substituents in the aromatic molecule influenced conversion and selectivity to the corresponding aldehyde. The presence of barbituric and cyanuric acids in the preparation method has changed the graphitic-C3N4 structure, …
Emotional Connotations of Musical Instrument Timbre in Comparison With Emotional Speech Prosody: Evidence From Acoustics and Event-Related Potentials
2018
Music and speech both communicate emotional meanings in addition to their domain-specific contents. But it is not clear whether and how the two kinds of emotional meanings are linked. The present study is focused on exploring the emotional connotations of musical timbre of isolated instrument sounds through the perspective of emotional speech prosody. The stimuli were isolated instrument sounds and emotional speech prosody categorized by listeners into anger, happiness and sadness, respectively. We first analyzed the timbral features of the stimuli, which showed that relations between the three emotions were relatively consistent in those features for speech and music. The results further e…
L'interprete al cinema: stereotipi, pregiudizi e realtà
2020
The figure of the interpreter in history has always oscillated between visibility and invisibility. Although today there is a tendency to give it increasing recognition, some categories (cultural mediators, war and sign interpreters) still remain in a poorly recognized situation and often operate in precarious working conditions. The interpreter as a subject of study has been present in world literature for years. We will investigate what has become the interpreter as a subject in world cinema. What is the semiotic process for which a given image of the interpreter communicates a certain cliché or suggests certain characteristics that the director (or the screenwriter) wanted to highlight. …
Sentence-Level Effects of Literary Genre: Behavioral and Electrophysiological Evidence
2017
The current study used event-related brain potentials (ERPs) and behavioral measures to examine effects of genre awareness on sentence processing and evaluation. We hypothesized that genre awareness modulates effects of genre-typical manipulations. We manipulated instructions between participants, either specifying a genre (poetry) or not (neutral). Sentences contained genre-typical variations of semantic congruency (congruent/incongruent) and morpho-phonological features (archaic/contemporary inflections). Offline ratings of meaningfulness (n = 64/group) showed higher average ratings for semantically incongruent sentences in the poetry vs. neutral condition. ERPs during sentence reading (n…
«A/traverso» la transizione. Le pratiche culturali del movimento del ’77 e il paradigma artistico
2012
Il cosiddetto movimento del ’77, già negli anni della sua emersione ricondotto alle esperienze delle avanguardie artistiche del primo Novecento, riconfigurò i dispositivi di produzione-fruizione della cultura producendo un capovolgimento – orientato verso l’autorappresentazione politica dell’emergente proletariato giovanile – delle tradizionali categorie e mediazioni sociali ancora agenti nella società fordista.
Decoding brain activities of literary metaphor comprehension: An event-related potential and EEG spectral analysis
2022
Novel metaphors in literary texts (hereinafter referred to as literary metaphors) seem to be more creative and open-ended in meaning than metaphors in non-literary texts (non-literary metaphors). However, some disagreement still exists on how literary metaphors differ from non-literary metaphors. Therefore, this study explored the neural mechanisms of literary metaphors extracted from modern Chinese poetry by using the methods of Event-Related Potentials (ERPs) and Event-Related Spectral Perturbations (ERSPs), as compared with non-literary conventional metaphors and literal expressions outside literary texts. Forty-eight subjects were recruited to make the semantic relatedness judgment afte…
Spoken-Word Segmentation and Dyslexia
2002
We used magnetoencephalography to elucidate the cortical activation associated with the segmentation of spoken words in nonreading-impaired and dyslexic adults. The subjects listened to binaurally presented sentences where the sentence-ending words were either semantically appropriate or inappropriate to the preceding sentence context. Half of the inappropriate final words shared two or three initial phonemes with the highly expected semantically appropriate words. Two temporally and functionally distinct response patterns were detected in the superior temporal lobe. The first response peaked at approximately 100 msec in the supratemporal plane and showed no sensitivity to the semantic appr…
Assessing the case of Dengue in Argentina 2009: discrimination and fear
2010
After almost a decade, the re-appearance of Dengue in Argentina caused panic and fears. Unlike Bolivia, Brazil and Paraguay where policies of preventions have been followed, the future of dengue is uncertain for Argentina; this paper does not have any political affiliation but emphasizes the role that mass media play in the coverage of epidemics. The question as to whether a newspaper or mass media corporation should maintain a minimum of objectivity is too complex to be resolved in this short article. However, we have so far set forth a model which will help other researchers to interpret topics of this nature in the future. In moments of disorder, uncertainty or disaster, societies experi…
Gesture’s body orientation modulates the N400 during semantic integration of gesture and visual sentence
2020
AbstractBody orientation of gesture entails social-communicative intention, and may thus influence how gestures are perceived and comprehended together with auditory speech during face-to-face communication. To date, despite the emergence of neuroscientific literature on the role of body orientation on hand action perception, limited studies have directly investigated the role of body orientation in the interaction between gesture and language. To address this research question, we carried out an EEG experiment presenting to participants (n=21) videos of frontal and lateral hand gestures of five-seconds (e.g., raising a hand), followed by visually presented sentences that are either congrue…
Clinical management of drug-drug interactions in HCV therapy: Challenges and solutions.
2013
Contains fulltext : 118153.pdf (Publisher’s version ) (Open Access) Hepatitis C virus (HCV) infected patients often take multiple co-medications to treat adverse events related to HCV therapy, or to manage other co-morbidities. Drug-drug interactions associated with this polypharmacy are relatively new to the field of HCV pharmacotherapy. With the advent of the direct-acting antivirals telaprevir and boceprevir, which are both substrates and inhibitors of the cytochrome P450 (CYP) 3A iso-enzyme, knowledge and awareness of drug-drug interactions have become a cornerstone in the evaluation of patients starting and continuing HCV combination therapy. In our opinion, an overview of conducted dr…
