Carbonate/evaporitic sedimentation during the Messinian salinity crisis in active accretionary wedge basins of the northern Calabria, southern Italy
2020
Abstract This work deals with Messinian deposits belonging to the Neogene infill of the Rossano and Belvedere Basins, respectively developed along the fore-arc and the back-arc areas of the north Calabria accretionary wedge. The main goal is to characterize the carbonate and evaporitic sedimentation during the Messinian Salinity Crisis, in the general framework of the basin architecture and the interplay between eustatic vs tectonic controlled sea-level variations. Fieldwork integrated with seismic lines and well logs interpretations led to the revision of the general stratigraphy of the basins and the proposal of a new sequential stratigraphic model driven by cyclic sea-level variations. E…
GEOV1: LAI, FAPAR essential climate variables and FCOVER global time series capitalizing over existing products. Part 2: Validation and intercomparis…
2013
International audience; This paper describes the scientific validation of the first version of global biophysical products (i.e., leaf area index, fraction of absorbed photosynthetically active radiation and fraction of vegetation cover), namely GEOV1, developed in the framework of the geoland-2/BioPar core mapping service at 1 km spatial resolution and 10-days temporal frequency. The strategy follows the recommendations of the CEOS/WGCV Land Product Validation for LAI global products validation. Several criteria of performance were evaluated, including continuity, spatial and temporal consistency, dynamic range of retrievals, statistical analysis per biome type, precision and accuracy. The…
Effect of Multiple Stressors on marine organism predicted and quantified through bioenergetic mechanistic models
Anthropogenic pressure on coastal ecosystems is vast and diverse, simultaneous impacts such as pollution, eutrophication and fishing pressure nowadays add up and interact with the effects of climate change (e.g., global warming, acidification and sea level rise). The magnitude of these effects on marine species and their replies can vary and the possible changes can depend on: i) species life-histories (LH) traits, ii) local environmental conditions and iii) contextual presence of more than one anthropogenic related stressor. The study of a single anthropogenic disturbance or Climate Change-derived alteration on multi-level ecological responses is misleading and generates unrealistic conclu…
Transport policy and climate change: How to decide when experts disagree
2008
Abstract Transport is the sector with the fastest growth of greenhouse gases emissions in many countries. Accumulation of these emissions may cause uncertain and irreversible adverse climate change impacts. In this context, we use the analytic hierarchy process (AHP) to face the question on how to select the best transport policy if the experts have different opinions and beliefs on the occurrence of these impacts. Thus, both the treatment of uncertainty and dissent are examined for the ranking of transport policies. The opinions of experts have been investigated by a means of a survey questionnaire. A sensitivity analysis of the experts’ weights and the criteria’ weights confirms the robus…
Socioemotional behavior and school achievement in relation to extracurricular activity participation in middle childhood
2012
This 3-year longitudinal study investigated the associations of student (aged 9 to 10 years at the beginning of the study; n = 281; 51% girls) participation in extracurricular activities with teacher-rated socioemotional behavior and school achievement. MANOVA results showed that, after controlling for the grade level and the initial level of the outcome variables, participation in arts and crafts and music activities was related to higher adaptive behavior, academic attainments (i.e., reading, writing, arithmetic), and working skills (persistence, concentration, carefulness). Participation in performing arts was associated with higher academic working skills, and participation in academic …
Engineering Self-adaptive Systems: From Experiences with MUSA to a General Design Process
2019
Designing and developing complex self-adaptive systems require design processes having specific features fitting and representing the complexity of these systems. Changing requirements, users’ needs and dynamic environment have to be taken in consideration, also considering that, due of the self-adaptive nature of the system, the solution is not fixed at design time but it is a run-time outcome. Traditional design approach and life cycles are not suitable to design software systems where requirements continuously change at runtime. A new design process paradigm is needed to design such systems. In this Chapter, we present a retrospective analysis based on three projects developed in the las…
Birds facing climate change: a qualitative model for the adaptive potential of migratory behaviour
2015
Recent climate change is altering the migratory behaviour of many bird species. An advancement in the timing of spring events and a shift in the geographical distribution have been detected for birds around the world. In particular, intra-Palearctic migratory birds have advanced arrivals in spring and shortened migratory distances by shifting northward their wintering grounds. These changes in migratory patterns are considered adaptive responses facilitating the adjustment of the life cycle to the phenological changes found in their breeding areas. However, in some cases, populations exposed to the same selective pressures do not show any appreciable adaptive change in their behaviour. Basi…
Physical activity and fat-free mass during growth and in later life.
2021
ABSTRACT Background Physical activity may be a way to increase and maintain fat-free mass (FFM) in later life, similar to the prevention of fractures by increasing peak bone mass. Objectives A study is presented of the association between FFM and physical activity in relation to age. Methods In a cross-sectional study, FFM was analyzed in relation to physical activity in a large participant group as compiled in the International Atomic Energy Agency Doubly Labeled Water database. The database included 2000 participants, age 3–96 y, with measurements of total energy expenditure (TEE) and resting energy expenditure (REE) to allow calculation of physical activity level (PAL = TEE/REE), and cal…
Mediación en derecho administrativo
2018
Presenciamos un momento de creciente fascinación por la mediación. Sin embargo, el Derecho administrativo se presenta históricamente como un ámbito plagado de obstáculos frente a las ADR y, por tanto, frente a la mediación. Sin embargo, los cambios sociales y la mutación de las estructuras administrativas llevan a buscar nuevos cauces para la resolución de los conflictos con la Administración. La mediación se ha visto fuertemente impulsada por la Unión Europea y en el ámbito interno, el Consejo General del Poder Judicial ha propiciado la incorporación de la mediación administrativa mediante proyectos pilotos que impulsan el consenso.
Physical activity experiences of children and adolescents with asthma: a qualitative systematic review protocol
2020
Objective: The objective of the review is to synthesize existing knowledge about experiences of children andadolescents with asthma related to participation in, or limitation of, physical activity.Introduction: Limitations of physical activity, expressed as a barrier of bodily movement, may relate to physiologicalrestraints, as well as emotional and social delimitation, in children and adolescents with asthma. Participation inphysical activity is related to management of asthma and is also important for social inclusion. Through childhoodand adolescence, physical activity enhances physical, cognitive, and social development, and a dose-responserelationship between physical activity and seve…
