È evidente come la nostra società tecnologica sia legata senza alcun dubbio alla diffusione delle immagini. Autori come Gottfried Boehm, John Mitchell, Hans Belting hanno indagato la natura dell'immagine ponendo le basi, negli anni Novanta, per l'idea di un pictorial turn, di una cultura totalmente dominata dalle immagini che è diventata adesso una possibilità tecnica reale su scala globale. Un nuovo statuto dell'immagine che si usa raccogliere sotto l'etichetta di iconic turner inserito nel più vasto campo visual culture studies. L'uso del termine cultura accanto a quello di visuale è indicativo dell'ampiezza del campo d'indagine che visual culture studies si prefiggono di ricercare: essi …

It is evident that our technological society is undoubtedly linked to the diffusion of images. Authors such as Gottfried Boehm John Mitchell Hans Belting investigated the nature of the image by laying the foundations in the 1990s for the idea of ​​a pictorial turn of a culture totally dominated by images that has now become a real technical possibility on global scale. A new statute of the image that is used to collect under the label of iconic turner inserted in the wider field of visual culture studies. The use of the term culture alongside that of visual is indicative of the breadth of the field of investigation that visual culture studies aim to seek: they do not want to limit themselves to ascertaining the predominance of the visual in contemporary society and an evaluation of its aesthetic component. but they want to proceed towards an anthropological research in which visual culture is analyzed as a particular lifestyle that expresses certain meanings and values ​​not only in art and high culture but also in institutions and daily behavior. We will try to apply this new paradigm to photographs: instead of asking ourselves what the images mean let's try to ask ourselves what they want.

Volatiles in pantellerite magmas: A case study of the Green Tuff Plinian eruption (Island of Pantelleria, Italy)

2013

Abstract The Green Tuff (GT) Plinian eruption, the largest in magnitude at Pantelleria, erupted 3 to 7 km3 DRE of pantellerite magma and a small volume of trachyte. Fifty-nine anorthoclase-hosted melt inclusions from the two basal pumice members were analyzed by FT-IR spectroscopy in order to assess the pre-eruptive H2O content in the pantellerite melt. Microanalytical methods were used to determine major element, Cl, F and S contents. Melt inclusions and glassy groundmasses have a nearly homogeneous pantelleritic composition (peralkaline index = 1.9-2.2) and variable water contents ranging from 1.4 to as high as 4.2 wt %, i.e. much higher than the 1.4 wt % of earlier published studies. The…

The chlorine content is constant at about 1 wt %. Combined Cl and H2O data were used to estimate a confining pressure of about 50 MPa (depth around 2-3 km) for the GT magma chamber. The chamber was characterized by a compositional zoning with a dominant pantellerite overlying a trachyte magma. Soon after the GT eruption intra-caldera volcanism was dominated by the eruption of voluminous trachyte lavaflows while pantellerite melt production resumed after about 20 ka with numerous low-volume mildly explosive (Strombolian) to effusive eruptions. Comparison with data from the literature reveals that despite the differentexplosivity the post-caldera Strombolian eruptions and the GT Plinian eruption were fed by pantelleritic magmas with similar water contents. Chlorine and CO2contents suggest that the young magma reservoirs feeding the Strombolian to effusive activity were deeper (h≥4.5 km) than the much larger (based on erupted volumes) magma chamber which fed the GT eruptionGeologyMelt inclusionsJournal of Volcanology and Geothermal Research

Physical activity and ability to meet different work requirements among adult working men with or without current depressive symptoms

2021

Abstract Purpose To examine the relationship between leisure-time physical activity (LTPA) and ability to meet different work requirements among adult working men with or without current depressive symptoms. Methods We measured LTPA with the long version of the International Physical Activity Questionnaire (IPAQ). The Work Ability Index (WAI) and Beck Depression Inventory (BDI) were used to assess the work ability and depression of 921 Finnish employed male volunteers. Participants were divided into three groups according to the WAI for their work requirements: mental (MENT), physical (PHYS), and an equal amount of mental and physical work (BTH). Results When adjusted for age, BMI and emplo…

Adapted Metrics for Dominated splittings.

2007

International audience; A Riemannian metric is adapted to an hyperbolic set of a diffeomorphism if, for this metric, the expansion/contraction of the unstable/stable directions can be seen after only one iteration. A dominated splitting is a notion of weak hyperbolicity where the tangent bundle of the manifold splits in invariant subbundles such that the vector expansion on one bundle is uniformly smaller than on the next bundle. The existence of an adapted metric for a dominated splitting has been asked by Hirsch Pugh and Shub who answer positively to the question in the special case of a dominated splitting in two bundles, one being of dimension 1. This paper gives a complete answer to th…

Common Fixed Points of a Pair of Hardy Rogers Type Mappings on a Closed Ball in Ordered Dislocated Metric Spaces

2013

Common fixed point results for mappings satisfying locally contractive conditions on a closed ball in an ordered complete dislocated metric space have been established. The notion of dominated mappings is applied to approximate the unique solution of nonlinear functional equations. Our results improve several well-known conventional results.

Análisis del comportamiento de la demanda de turismo rural desde la experiencia de la comarca El Alto Palancia

2004

This study is intended to delve into the tastes and preferences of tourists visiting rural areas in Spain as an alternative to the traditional sun and beach holiday that dominates Spanish tourism. This paper is focused on the demand side of rural tourism; more specifically the extent to which tourists visiting a Spanish rural area. El Alto Palancia region, exhibit different behaviours depending on age, gender, incomes and educational background. The homogeneity of behaviour across several categories of tourists was tested in two sets of variables. First, «interest in certain resources associated with rural tourism», focused on natural and architectural resources that sustains the tourist's …

Revisión de la sección del yacimiento del Mas de la Chimenea Alta (Formación Arcillas de Morella, Castellón) y significado en el contexto paleoambien…

2012

Desde los primeros estudios estratigráficos y paleontológicos, que datan de principios del siglo XX, la Fm Morella se ha caracterizado por su coloración rojiza y su contenido fósil. La mayor parte de sus depósitos se han interpretado como continentales, aunque con intercalaciones locales de materiales marinos. En esta unidad se da la paradoja de que muchos de los lugares descritos con fauna de vertebrados continentales se encuentran en depósitos interpretados como ambientes marinos poco profundos y de transición. La sección del Mas de la Chimenea Alta es un ejemplo. Ésta contiene yacimientos con fósiles de vertebrados que son claramente alóctonos, pero también otros, con icnitas que permite…

On the a posteriori error analysis for linear Fokker-Planck models in convection-dominated diffusion problems

2018

This work is aimed at the derivation of reliable and efficient a posteriori error estimates for convection-dominated diffusion problems motivated by a linear Fokker-Planck problem appearing in computational neuroscience. We obtain computable error bounds of the functional type for the static and time-dependent case and for different boundary conditions (mixed and pure Neumann boundary conditions). Finally, we present a set of various numerical examples including discussions on mesh adaptivity and space-time discretisation. The numerical results confirm the reliability and efficiency of the error estimates derived.

Dynamic instability in absence of dominated splittings.

2006

We want to understand the dynamics in absence of dominated splittings. A dominated splitting is a weak form of hyperbolicity where the tangent bundle splits into invariant subbundles, each of them is more contracted or less expanded by the dynamics than the next one. We first answer an old question from Hirsch, Pugh and Shub, and show the existence of adapted metrics for dominated splittings.Mañé found on surfaces a $C^1$-generic dichotomy between hyperbolicity and Newhouse phenomenons (infinitely many sinks/sources). For that purpose, he showed that without a strong enough dominated splitting along one periodic orbit, a $C^1$-perturbation creates a sink or a source. We generalise that last…

Anthropogenic Influences in Land Use/Land Cover Changes in Mediterranean Forest Landscapes in Sicily

2016

This paper analyzes and quantifies the land use/land cover changes of the main forest and semi-natural landscape types in Sicily between 1955 and 2012. We analyzed seven representative forest and shrubland landscapes in Sicily. These study areas were chosen for their importance in the Sicilian forest panorama. We carried out a diachronic survey on historical and current aerial photos; all the aerial images used to survey the land use/land cover changes were digitalized and georeferenced in the UTM WGS84 system. In order to classify land use, the Regional Forest Inventory 2010 legend was adopted for the more recent images, and the CORINE Land Cover III level used for the older, lower resolut…
