SENZA COMMETTERE UN FALSO STORICO. Il restauro della ex chiesa Madre di Santa Margherita di Belice dopo il terremoto del 1968 / The restoration of th…
2018
Il restauro persegue l’obiettivo di preservare il carattere autentico dell’architettura storica e le sue stratificazioni, rendere distinguibili le aggiunte e proporre un uso compatibile. Questa posizione culturale ha sostenuto l’intervento condotto sui resti dell’ex chiesa Madre a Santa Margherita di Belice in Sicilia, distrutta da un terremoto nel 1968, che oggi ospita il Museo della Memoria. Esclusa l’iniziale proposta di ripristino delle parti crollate, il progetto di restauro è stato indirizzato verso la conservazione critica del frammento autentico, la reintegrazione della fabbrica lacunosa e la ridefinizione dell’involucro architettonico con componenti strutturali dal carattere potenz…
"Nel più fulgido scenario di colori” Goethe e la scoperta del paradiso a Napoli
2017
Dopo avere visitato Roma, nel febbraio del 1787, J.W. Goethe giungeva a Napoli dove: «l’atmosfera si faceva sempre più pura, ormai ci trovavamo in un’altra terra». Nella seconda metà del Settecento, in Europa il poeta di Francoforte rappresentava certamente il massimo fra i divulgatori del mito del paradiso a Napoli e in Campania, ma anche in Sicilia, e dunque nel Meridione d’Italia, sia per la loro rigogliosa e sempre verde natura sia per l’abbondanza delle loro antichità classiche. A Roma Goethe aveva pregustato i frutti di questo paradiso, ma è solo visitando Napoli e il suo territorio che realizza di essere in un altro mondo, totalmente diverso dai paesi del Nord. Il presente saggio ha …
Why do university students choose tourism degrees? Interests analysis and employ-ment expectations for students from Universitat de València
2019
Las expectativas del alumnado que determinan la elección de una titulación en Turismo condicionan sus conductas durante y después de sus estudios. Para identificar estas expectativas se realizó una encuesta al alumnado de Turismo de primer curso. Un análisis factorial nos ha permitido identificar los factores de mayor peso en la elección: Internacionalización, Expectativas de empleo, Emprendimiento, Importancia del sector e Interés por la titulación. Finalmente, se ha completado el estudio analizando sus expectativas sobre las salidas profesionales vinculadas al ámbito turístico. Interests that drive students to choose a Tourism degree will condition their behaviour in their studies and lat…
¿Por qué conservamos la biodiversidad? Un breve recorrido sociológico, psicológico y moral
2017
espanolEn este trabajo se muestran, de manera muy sucinta, algunos conceptos fundamentales sobre los valores que subyacen en la toma de las decisiones sobre la conservacion de la biodiversidad, asi como las bases psicologicas de la deliberacion en este contexto. Para ello, se describe, en primer lugar, un modelo sociologico clasico que ayuda a predecir la asignacion de recursos para la conservacion, basado en la construccion social y el poder “politico” oculto de las diferentes especies. En segundo lugar, se vincula dicho modelo con la taxonomia de valores subyacentes (no necesariamente excluyentes). Finalmente, se discute la base psicologica de la deliberacion valorativa a partir de la teo…
Ex situ conservation and exploitation of fungi in Italy
2011
Abstract The kingdom Fungi comprises one of the most diverse groups of living organisms. They are numerous, ubiquitous and undertake many roles both independently and in association with other organisms. Fungi display a wide diversity of forms also mirrored by functional diversity and play such a dominant role in human society that they are arguably biotechnologically the most important group of organisms. Ex situ conservation of fungi, not only guarantees correct management and conservation of biodiversity, but also its exploitation in different fields. This article describes the major biological resource centres dealing with fungi in Italy and gives several examples of fungal exploitation…
Modelling urban networks at mega-regional scale: Are increasingly complex urban systems sustainable?
2015
Are the dynamics of mega-regions sustainable or not? We explore the hypothesis that increasing complexity in mega-regions implies less demands on resources needed to generate organized information, thereby making the systems more efficient and stable. This article aims to identify structural indicators for measuring urban networks at the mega-regional scale. We use night-time light data from the broad band near-visible infrared channel of the DMSP-OLS to monitor the dynamics of urbanization. We study the urban networks as graphs, where nodes are cities, and the main road and railway infrastructures represent the edges. We propose four indicators for measuring the complexity, polycentricity,…
The European Union can afford greater ambition in the conservation of its threatened plants
2021
The importance of Natura 2000 network for the conservation of natural habitats, wild flora and fauna at European level is undeniable. However, it may not have reached its full potential since the loss of biodiversity continues to increase year on year. Further on, a third of the plant species listed in the Habitats Directive to guide the declaration of European Union Natura 2000 network of protected areas is not threatened and there is broad agreement on the need to review and update the species list. Here, the effectiveness of Natura 2000 in the conservation of Spanish bryophytes and vascular plants included in the Habitats Directive Annex II is analysed and compared with the one offered t…
Path dependency and landscape biographies in Latgale, Latvia: a comparative analysis
2010
This paper focuses on the path dependency of landscapes in Latgale, Latvia from the present perspective at the regional and local scale. During the last centuries Latvia's landscapes have passed through radical changes, which were driven by political events. Each new political era discarded the ideas of the previous era and subsequently reorganized the land(scape) according to the new views. At the regional level the role of history is significant in analyzing landscapes while at the local level the main force is people, often themselves not knowing the history of the place but putting the existing path dependency into practise or disregarding it. The biographies of two former villages are …
G.I.S. context analysis for environmental recovery suitability evaluation
2009
The attributes of every single patch in a land mosaic constitute the database that landscape ecologists use for processing and analysis. Nonetheless spatial and ecological relationships between adjacent patches can play a key role in understanding the overall functionality of land mosaics. Defining the ecological role of a single tessera within an ecosystem is not possible if that patch is regarded as an insular element; on the other hand global analysis on the entire land mosaic would grant just a small amount of new information on each tessera and none on its functional role. To recognize areas susceptible of improvement through environmental recovery and to define priorities for interven…
Drought-induced positive feedback in xylophagous insects: Easier invasion of Scots pine leading to greater investment in immunity of emerging individ…
2012
Abstract We studied the infestation rate of Scots pine Pinus sylvestris by xylophagous insects in relation to distance from forest lakes in eastern Latvia, northern Europe. In summers of 2008 and 2009, we felled 72 pines of approximately 65 years age. Sections of the logs were incubated in insect emergence traps. The trees located near lakes were significantly less infested by xylophagous insects than those sampled at greater distances from the lakes. We also tested the ability of Tomicus piniperda , the most abundant species of xylophagous insects in our samples, to resist the entomopathogenic fungus Beauveria bassiana . The results show that beetles captured near lakes were more susceptib…
