La racionalidad y la sostenibilidad como figuras míticas en el desmontaje del sistema público de servicios sociales
2014
Este artículo constituye un balance de los cambios que se están produciendo en el sistema de servicios sociales de la Comunidad Valenciana: 1) Una contextualización en un eje histórico que concluye con la actual búsqueda de un “consenso retrógrado” para desmontar el sistema público y los movimientos sociales de resistencia; 2) El desplazamiento de la contención social de la crisis desde el sistema de servicios sociales al de seguridad social; 3) Las transformaciones institucionales producidas por la vía presupuestaria; 4) El “efecto bumerang” sobre los Servicios Sociales que produce la implementación de la Ley de “promoción de la autonomía personal y apoyo a las situaciones de dependencia”;…
Applicazione dell’analisi tridimensionale negli studi di Ecologia del paesaggio
2010
Topography and terrain morphology play a key role in landscape structure and functionality. Landscape ecology modelling based on patch-corridor-matrix usually analyzes the area of study as a plane surface. However, this assumption could be critically far from reality, especially in mountainous areas, and lead to significant mistakes in calculation. Different areas of study were analyzed using both classical and more recent indices. Calculation was performed using a bi-dimensional terrain model and a three-dimensional model in which length and surface area values were much closer to real world values. Results were confronted to understand the different sensitivity of various analysis tools t…
Impact of COVID-19 on aquaculture sector in Malaysia: Findings from the first national survey
2021
Abstract Malaysian aquaculture sector consists of 391,000 t of cultivated organisms produced per year with an economic value for over USD 700 million as estimated in 2019. The COVID-19 pandemic caused a large global human pandemic and it is currently ongoing, affecting profoundly Malaysian aquaculture, which is vital for seafood provision and security assurance. Thus, to increase our understanding about how the pandemic affects aquaculture sectors is crucial to design possible management measures both at local and national level. To do it, we designed a survey, starting in May 2020, consisting of 25 online questions to collect information about the impact of COVID-19 on the aquaculture sect…
Factors affecting fish assemblages associated with gas platforms in the Mediterranean Sea
2013
Abstract Understanding the role played by offshore platforms in marine ecosystems is acquiring increasing importance worldwide. In this work, underwater visual census techniques were applied to describe spatial and temporal patterns of fish assemblages associated with extractive platforms. Data were collected during three seasons according to the following spatial factors: Location (Adriatic and Ionian Seas), Depth (0–6 m and 12–18 m) and Distance from the platform (external and internal). Both univariate and multivariate analyses showed highly significant differences for each factor assessed in this study, as well as for the interaction among said factors. Results indicated that artificial…
Fish diversity associated with gas platforms: Evaluation of two underwater visual census techniques
2007
Se estudiaron las comunidades ícticas asociadas con plataformas extractivas mediante dos técnicas de censos visuales submarinos: transectos y conteos de puntos móviles. Los datos se tomaron a cuatro profundidades en tres diferentes plataformas situadas en el Mar Jónico (Crotone, Italia). Se registraron un total de 25 especies de peces pertenecientes a 12 familias. Se observaron diferencias significativas entre ambos métodos de muestreo y las profundidades en cuanto a la estructura de la comunidad íctica, la riqueza de especies y la abundancia de peces. El promedio de peces registrado con el método de transectos siempre fue mayor que el registrado mediante puntos móviles, mientras que lo con…
Facies and geometry of an Upper Jurassic-Lower Cretaceous carbonate rimmed-shelf system from Northwestern Sicily
2011
Upper Jurassic-Lower Cretaceous carbonate shallow-water successions, several hundreds of meters thick, outcropping in the Palermo Mountains (NW Sicily, Italy), are analyzed in their sedimentological features for environmental reconstructions. In the Palermo Mts., the northernmost thrust system of the western Sicily fold and thrust belt, tectonic bodies, consisting of Upper Triassic-to-Eocene shallow-water carbonates (Panormide carbonate platform), outcrop. Detailed facies and microfacies analyses, stratigraphic measurements and physical stratigraphy studies of the Tithonian-Neocomian carbonates point out the occurrence of several lithofacies, from tidal flat to reef environments. Due to the…
Processi paleocarsici e geositi: il caso del “libeccio antico” nel distretto marmifero di Custonaci, Sicilia nord-occidentale
2016
Abstract The Upper Triassic strata that crops out along the northern slope of Monte Sparagio, in the Custonaci “marble” district in northwestern Sicily, show an extensive development of dissolution cavities with a very variable shape and dimensions. Several different types of dissolution morphologies can be differentiated from microkarst to giant caverns. The cavities are filled up by polychrome silts or calcite cements or, in the larger caverns, by collapse breccias. The matrix between the collapse breccias is a polychrome silt that gives rise to an attractive ornamental stone, quarried in the past with the name of “Libeccio Antico”. The diagenetic processes that have controlled the format…
