Modélisation des choix d'itinéraires pédestres en milieu urbain. Approche géographique et paysagère
2006
Nowadays, on foot journeys create renewed interest as a complementary mode of transport. Indeed, local decision makers appear as willing to reduce the imbalance between different ways of transport within the cities. In the field of Geography the term ‘mobility' refers to the practice of exchanges and movements done by individuals or groups of individuals; this mobility is likely to reveal the characteristics of places and to contribute to their alteration. Among all the modes of transport, walking implies a privileged relation between persons and area they live in. As an element of the living environment used on a daily basis and eventually integrated by the prism of perception the visible …
Mapping a language aware educational landscape
2018
This article is based on a poster presented at the 2017 FERA conference at the University of Lapland, Rovaniemi (Figure 1). The poster aims to provide a visual aid to enhance discussions with in- and pre-service teachers as well as educational researchers around the role of language in education. The perspectives presented here are intended to provide different ‘entry points’ into language awareness and highlight different considerations. This contribution begins by outlining why language awareness is needed before introducing the six entry points we use to map a language aware educational landscape. Hopefully the discussion will continue in different forums and the model will also be devel…
Caratterizzazione geotecnica del comporportamentodi una grande frana in argille varicolori in Sicilia
2014
Si illustrano le misure degli spostamenti e delle pressioni neutre raccolte in un paio d’anni di osservazione del comportamento di un esteso corpo di frana in una formazione di argille varicolori in Sicilia. L’analisi delle misure raccolte indica che la riattivazione riguarda zone distinte del corpo di frana, nelle quali gli spostamenti si sviluppano con velocità e direzioni differenti. L’evoluzione degli spostamenti è manifestamente dipendente dalle condizioni climatiche, dal momento che essi aumentano al crescere delle pressioni interstiziali, a loro volta regolate dalle piogge, e rallentano nella stagione secca, spesso senza annullarsi del tutto. Analisi a ritroso effettuate in una delle…
IL RUOLO DELLE AREE AGRICOLE NELLA PROGETTAZIONE TERRITORIALE. Gli aspetti sociali come forma di rivitalizzazione del territorio.
2014
La tesi indaga il tema della multifunzionalità applicata all’agricoltura come strumento per riattivare territori abbandonati, degradati, a rischio di uso improprio o di nuova edificazione. L’agricoltura ha sempre avuto un rapporto fondamentale con l’Uomo e con gli insediamenti. Il rapporto tra centri abitati e aree agricole è stato un rapporto di unione e di contrapposizione. Nel passaggio da agricoltura di sussistenza a quella di tipo intensivo e specializzato sono stati coinvolti gli spazi, le tecniche, gli strumenti, le opere legate all’attività agricola e, infine, il rapporto con il territorio. L’agricoltura, benché produca beni di prima necessità, nei decenni scorsi è stata considerata…
Conceptualizing ecosystem tipping points within a physiological framework
2017
Connecting the nonlinear and often counterintuitive physiological effects of multiple environmental drivers to the emergent impacts on ecosystems is a fundamental challenge. Unfortunately, the disconnect between the way “stressors” (e.g., warming) is considered in organismal (physiological) and ecological (community) contexts continues to hamper progress. Environmental drivers typically elicit biphasic physiological responses, where performance declines at levels above and below some optimum. It is also well understood that species exhibit highly variable response surfaces to these changes so that the optimum level of any environmental driver can vary among interacting species. Thus, specie…
Predicting Earthquake-Induced Landslides by Using a Stochastic Modeling Approach: A Case Study of the 2001 El Salvador Coseismic Landslides
2023
In January and February 2001, El Salvador was hit by two strong earthquakes that triggered thousands of landslides, causing 1259 fatalities and extensive damage. The analysis of aerial and SPOT-4 satellite images allowed us to map 6491 coseismic landslides, mainly debris slides and flows that occurred in volcanic epiclastites and pyroclastites. Four different multivariate adaptive regression splines (MARS) models were produced using different predictors and landslide inventories which contain slope failures triggered by an extreme rainfall event in 2009 and those induced by the earthquakes of 2001. In a predictive analysis, three validation scenarios were employed: the first and the second …
Factor selection procedures in a Google Earthtm aided landslide susceptibility model: application to the Beiro river basin (Spain)
2011
A procedure to select the controlling factors connected to the slope instability has been defined. It allowed to assess the landslide susceptibility in the Rio Beiro basin (about 10 km2) over the north-eastern area of the city of Granada (Spain). Field and remote (Google EarthTM) recognition techniques allowed to generate a landslide inventory consisting in 127 phenomena. Univariate tests, using both association coefficients and validation results of single parameter susceptibility models, allowed to select among 15 controlling factors the ones that resulted as good predictor variables; these have been combined for unique conditions analysis and susceptibility maps were finally prepared. In…
I musei naturalistici come presidi ambientali e culturali. L'Orto botanico di Palermo
2013
La funzione degli Orti botanici, fondamentalmente, si esplica nella conservazione, nella ricerca scientifica, nelle attività espositive ed educative. I punti di forza dell’azione sociale di questi tipi di musei deriva sia dalla capacità di produrre e diffondere la conoscenza scientifica, sia dalla ricchezza patrimoniale posseduta. Una serie di emergenze planetarie e le prospettive incerte per l’ambiente, le società, le economie di tutte le nazioni del mondo configurano lo scenario d’oggi. Questa situazione richiede la costruzione collettiva di nuove forme di sentire, pensare e agire nella ricerca di soluzione ai problemi contemporanei. Si tratta quindi, per i musei scientifici, di intrapren…
Checklist of the Mammal Collection Preserved at the University of Palermo under the Framework of the National Biodiversity Future Center
2023
The latest reorganization of the Vertebrate collections preserved at the “Pietro Doderlein” Museum of Zoology of the University of Palermo (Italy) has made it possible to draw up a check-list of the Mammal taxa present in the stuffed (M), fluid-preserved (ML) and anatomical (AN) collections. The intervention was planned under the National Biodiversity Future Center (NBFC) agenda, focused on the enhancement of Italian natural history museums. The growing interest in museum collections strongly demands databases available to the academic and policy world. In this paper, we record 679 specimens belonging to 157 specific taxa arranged in 58 families and 16 orders. Most of the species (75.1%) co…
The shape of the water
2016
The Po River is a living organism that breathes: it inhales and swells; it exhales and releases its energy. Between two extreme phases of overflow and shallows, there are endless variations. In Piacenza, at the riverside, hydrometric instruments also took size and shape of a special building in reinforced concrete crowned by conical elements. When the water level rises, it floods the earth gradually; it deletes some marks lapping, and then reveals other things. The water clears and continuously constructs, in a surreal atmosphere of expectation, always in the balance between the catastrophe and the regeneration of a soil that emerges like an archaeological plan. Visible volumes are like the…
