MODELLI, TESTI, PROCESSI: UNO STUDIO COGNITIVO DELLE METAFORE DELESSICALIZZATE E D’INVENZIONE
2014
La tesi di ricerca è basata sulle metafore delessicalizzate e d’invenzione riscontrate all’interno del romanzo di lingua tedesca «Kassandra» scritto nel 1983 dalla scrittrice Christa Wolf e all’interno del racconto di lingua tedesca «Minotaurus: eine Ballade» scritto nel 1985 Friedrich Dürrenmatt. Si vogliono analizzare i processi cognitivi che stanno alla base della creazione dei due tipi di metafore. Per farlo si è scelto di utilizzare tre teorie della linguistica cognitiva: la teoria della metafora concettuale (Lakoff e Johnson, 1980 e 1999); la teoria dell’integrazione concettuale (Turner e Fauconnier, 2002) e la teoria dell’analogia (Monneret, 2004). L’analisi ci permette di comprender…
What is meant by hybridity? An investigation of hybridity and related terms in genre studies
2014
AbstractThis article is an investigation and a discussion of hybridity and related terms as used in linguistic studies of genre. The theoretical points that are made are illustrated with data from empirical research done by others and with the authors’ own data. The focus is on written texts but hybridity in spoken interaction is also discussed. The article defines the notion of genre and discusses (proto)typicality in relation to genre and hybridity. Recontextualization is also discussed. This is followed by a discussion of terms that have been used to talk about the processes of hybridity, firstly, as used in research that has mainly been done on spoken interaction. The focus then turns t…
Morphology and thermal properties of foams prepared via thermally induced phase separation based on polylactic acid blends
2012
Blends of poly-l-lactic acid with two different types of polylactic acid with different average molecular weights (50,000 and 175,000 g/mol, respectively) in different proportions (90/10, 80/20 and 70/30) were utilized in order to produce biodegradable and biocompatible scaffolds for soft tissue engineering applications. The scaffolds were produced via thermally induced phase separation starting from ternary systems where dioxane was the solvent and water the non-solvent. Morphology (average pore size and interconnection) was evaluated by scanning electron microscopy. Foams apparent density was also evaluated (porosity ranges from 87% to 92%). Moreover, a differential scanning calorimetry …
Poly lactic acid based foams prepared via thermally induced phase separation (TIPS): A method to tune the crystallinity
2012
Blends of Poly-L-Lactic Acid (PLLA) with two Poly-Lactic Acid (PLA) in different proportions (90/10 and 70/30) were utilized in order to produce biodegradable and biocompatible scaffolds for soft tissue engineering applications. The scaffolds were produced via thermally induced phase separation (TIPS) starting from ternary systems where dioxane was the solvent and water the non-solvent. Morphology was evaluated by Scanning Electron Microscopy (average pore size and interconnection). Moreover a DSC analysis was carried out on the as-obtained scaffold in order to obtain information about theirs thermal properties (enthalpy of melt and crystallization). The results showed that is possible to p…
Color Correction for Image Stitching by Monotone Cubic Spline Interpolation
2015
This paper proposes a novel color correction scheme for image stitching where the color map transfer is modelled by a monotone Hermite cubic spline and smoothly propagated into the target image. A three-segments monotone cubic spline minimizing color distribution statistics and gradient differences with respect to both the source and target images is used. While the spline model can handle non-linear color maps, the minimization over the gradient differences limits strong alterations on the image structure. Adaptive heuristics are introduced to reduce the minimization search space and thus computational time. Experimental comparisons with respect to the state-of-the-art linear mapping model…
Al cuore del fantastico. Ibridi da pensare nel Paleolitico
2022
Our narrative abilities go back before Chauvet. Already the ivory figure of the so-called Hohlenstein-Stadel Lion-Man, dated to about 40,000 years ago, must be regarded as the most advanced product of a hundred if not a thousand years of figurative and narrative experimentation. In order to create this hybrid figure, as well the more or less theriomorphic figures which populate caves all over the world, the human mind must have possessed developed narrative skills. All the imaginary animals found in prehistoric art and all the teratologies found in caves, presuppose a narrative, more precisely the story of a metamorphosis. In this contribution I propose an interpretation that investigates t…
Integrating Experiences: Palermo Mediterranean Gateway City. Identity and Innovation
2019
Metropolitan transformations of the Palermo as a Mediterranean city, guided by envisioning it as a ‘fluid’ gateway city, have been seen as an example for the planning of other such cities in Italy and Europe. The 2025 strategic vision for Palermo was inspired by three key components: (i) the relevance of Palermo as ‘hub territory’ in European level concerns in territorial and infrastructure development policies; (ii) the urban and regional experience with the concept ‘fluid city’ (envisioning the city as a portal and place of interaction and exchanges, not just in terms of goods and people); and (iii) new metropolitan vision produced by new regional and national legislation on metropolitan …
Structural, mechanical and thermal behavior assessments of PCL/PHB blends reactively compatibilized with organic peroxides
2018
Abstract The efficiency of two commercially available organic peroxides, dicumyl peroxide (DCP) and di-(2-tert-butyl-peroxyisopropyl)-benzene (BIB), during reactive processing of poly(e-caprolactone)/poly(3-hydroxybutyrate) (PCL/PHB) blends was investigated. The changes in chemical structure of PCL/PHB blends, as a function of organic peroxide type (DCP/BIB) and content (in range: 0–1.0 parts by weight - pbw), were characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis combined with infrared spectroscopy, and headspace analysis combined with gas chromatography with flame ionization detector. Performance properties of PCL/PHB blends were evaluated based on diffe…
The Uses of the Imagination in Moral Neuroeducation
2019
In contrast to influential theories that focus on top-down, deliberative reasoning, triune ethics theory seeks to gather findings from neurobiology, affective neuroscience, and cognitive science and integrate them into a bottom-up theory that focuses on that motivational orientations that are rooted in experientially formed, evolved, unconscious emotional systems. Triune ethics theory identifies three basic attractors for moral functioning based on brain evolution: safety, engagement and imagination. It proposes an integrative ethical education model based on the notion of a moral imagination, which can enhance moral development. It integrates, on the one hand, John Dewey’s theory of moral …
Perceptual odor blending is influenced by chemical complexity of odorant mixtures
2008
International audience; Perfumers and flavorists are familiar with odor blending phenomenon and often report that a minimum number of odorants has to be mixed for a good odor blend to arise. Previous studies in humans and animals suggested that a configural process could be involved in the perceptual analysis of mixtures of odorants. It has been proposed that the perceptual blending phenomenon corresponds to a configural perception of odorant mixtures. In the present study, we investigated the influence of chemical complexity on the configural perception of odorant mixtures. Six mixtures including 2 to 6 odorants as well as each unmixed odorant were assessed for their odor quality by a pane…
