Cinema e politiche del vino
2021
Se è vero che il cinema culinario, con le sue storie, pone il problema dell’alterità e della convivenza fra diversi, facendo interagire in un medesimo contesto personaggi portatori di identità culinarie/ culturali eterodosse (cfr. Mangiapane 2015), i film che mettono al centro delle loro storie il vino battono una strada diversa. Da qualche tempo, con la progressiva saturazione da parte dell’industria culturale di ogni possibile appiglio narrativo riconducibile alla cosiddetta gastromania (cfr. Marrone 2014), infatti, il vino ha acquisito una certa visibilità come soggetto cinematografico autonomo, ispirando film a esso interamente dedicati. È il caso di alcuni titoli emblematici: Sideways …
Oggetti interni e reaction objects come nomi predicativi di costrutti a verbo supporto
2011
Analyses regarding clauses with a cognate object (CO), e.g. Alice laughed a scornful laugh, have frequently been based on the query: is the CO an adjunct or a complement? This paper aims to contribute to the debate with an alternative suggestion: the CO functions as a noun predicate licensing the subject, to which it assigns a semantic role, whilst the verb functions as a support (a ‘light verb’). A number of the well-known properties of COs, e.g. certain constraints on the determiner, appear to corroborate this analysis. Clauses with the so-called reaction object (RO), e.g. Alice coughed a scornful laugh, are analyzed as multi-predicative as well: also the RO is a noun predicate which lice…
Inhibición cognitiva y comprensión lectora: un estudio sobre las diferencias individuales en los estudiantes de primer año de la Escuela de Psicologí…
2019
Resumen La lectura es un proceso cognitivo complejo, entendida como una interacción coordinada entre distintos niveles de procesamiento de la información: nivel de palabra, nivel de oración y nivel de discurso. Saber leer es, fundamentalmente, saber comprender; es entender el mensaje e integrarlo a nuestro conocimiento. Para ello, es necesario que se construyan estructuras mentales adecuadas sobre el texto que se lee. A través de estudios conductuales se conocen factores que contribuyen a las diferencias individuales de las habilidades de lectura y la comprensión del discurso, entre los cuales, tenemos: la capacidad de decodificación de palabras, la capacidad de supresión o de control cogni…
Functional CdSe and CdSe/ZnS nanoparticles capped with thiols: photophysical and photochemical properties and applications as sensors
2013
Esta tesis se centra en el efecto simbiótico entre los QDs de CdSe o CdSe/ZnS y sus ligandos orgánicos, y las ventajas de este efecto para mejorar la funcionalidad del QD y/o del ligando, o crear una nueva funcionalidad del sistema. Así : 1. la superficie de las nanopartícula recubierta con ligandos orgánicos puede permitir al QD i) permanecer estable en disolventes orgánicos o acuosos, debido a la repulsión estérica o iónica entre las nanopartículas, ii) mantener o aumentar sus propiedades emisivas (pasivación de los defectos de superficie, aumento de distancia entre nanopartícula y moléculas desactivadoras), y/o iii) para proporcionar funcionalidad a la nanopartícula. 2. la forma esférica…
Indeterminacy Reduction in Agent Communication Using a Semantic Language
2015
In recent years, the importance of vagueness and uncertainty in the messages exchanged between agents has been highlighted, mainly due to the ubiquitous nature of the (artificial or human) agents’ communication. The imprecision in the communication becomes more significant when the autonomy of the agents increases or the number of exchanged messages for a communicative goal is limited. In this paper we conjugate ideas drawn from situation semantics theory, human communication, and the multi-agent systems (MAS) field to reduce the impact of vagueness and uncertainty present in the communication. The main advances are achieved with the help of context information, collaboration and reinforcem…
Alkylsilyl compounds as enablers of atomic layer deposition: analysis of (Et3Si)3As through the GaAs process
2016
A new chemistry has been developed to deposit GaAs, the quintessential compound semiconductor. The ALD process is based on a dechlorosilylation reaction between GaCl3 and (Et3Si)3As. Characteristic ALD growth was demonstrated, indicating good applicability of the alkylsilyl arsenide precursor. ALD of GaAs produced uniform, amorphous and stoichiometric films with low impurity content. This was done with saturating growth rates and an easily controlled film thickness. Crystallization was achieved by annealing. Even though the growth rate strongly decreased with increasing deposition temperature, good quality film growth was demonstrated at 175 to 200 °C, indicating the presence of an ALD wind…
Progress in the Development of CdTe and CdZnTe Semiconductor Radiation Detectors for Astrophysical and Medical Applications
2009
Over the last decade, cadmium telluride (CdTe) and cadmium zinc telluride (CdZnTe) wide band gap semiconductors have attracted increasing interest as X-ray and gamma ray detectors. Among the traditional high performance spectrometers based on silicon (Si) and germanium (Ge), CdTe and CdZnTe detectors show high detection efficiency and good room temperature performance and are well suited for the development of compact and reliable detection systems. In this paper, we review the current status of research in the development of CdTe and CdZnTe detectors by a comprehensive survey on the material properties, the device characteristics, the different techniques for improving the overall detector…
A Qualitative and Quantitative Study on Ancient Latin Texts Concerning the Concept of aether : Some Methodological Considerations
2022
My study focuses on the semantic analysis of an ambiguous Latin word, aether, which may roughly be translated as ‘celestial substance’. The study is carried out by utilising both qualitative and quantitative methods on a digital text corpus containing Latin literature dating from ca. 200 BCE to 200 CE. In this paper, the compilation process and the contents of the corpus are described. Beside qualitative research (close reading), various computational methods are implemented on the corpus (distant reading). Of the latter, cosine similarity and correspondence analysis are discussed in this paper. I will explicate one way of combining qualitative and quantitative methods by assigning numerica…
HOWERD: A Hidden Markov Model for Automatic OWL-ERD Alignment
2016
The HOWERD model for estimating the most likely alignment between an OWL ontology and an Entity Relation Diagram (ERD) is presented. Automatic alignment between relational schema and ontology represents a big challenge in Semantic Web research due to the different expressiveness of these representations. A relational schema is less expressive than the ontology; this is a non trivial problem when accessing data via an ontology and for ontology storing by means of a relational schema. Existent alignment methodologies fail in loosing some contents of the involved representations because the ontology captures more semantic information, and several elements are left unaligned. HOWERD relies on a…
Spatialization of the Semantic Web
2012
syntax for Horn-like rules. The SWRL as the form, antecedentconsequent, where both antecedent and consequent are conjunctions of atoms written a1^ ... ^ an. Atoms in rules can be of the form C(x), P(x,y), Q(x,z), sameAs(x,y), differentFrom(x,y), or builtIn(pred, z1, ..., zn), where C is an OWL description, P is an OWL individual-valued property, Q is an OWL data-valued property, pred is a datatype predicate URIref, x and y are either individual-valued variables or OWL individuals, and z, z1, ... zn are either data-valued variables or OWL data literals. An OWL data literal is either a typed literal or a plain literal. Variables are indicated by using the standard convention of prefixing the…
