Spatial data fusion and analysis for soil characterization: a case study in a coastal basin of south-western Sicily (southern Italy)
2012
Salinization is one of the most serious problems confronting sustainable agriculture in semi-arid and arid regions. Accurate mapping of soil salinization and the associated risk represent a fundamental step in planning agricultural and remediation activities. Geostatistical analysis is very useful for soil quality assessment because it makes it possible to determine the spatial relationships between selected variables and to produce synthetic maps of spatial variation. The main objective of this paper was to map the soil salinization risk in the Delia-Nivolelli alluvial basin (south-western Sicily, southern Italy), using multivariate geostatistical techniques and a set of topographical, phy…

Dispersal ecology of deadwood organisms and connectivity conservation
2018
Limited knowledge of dispersal for most organisms hampers effective connectivity conservation in fragmented landscapes. In forest ecosystems, deadwood‐dependent organisms (i.e., saproxylics) are negatively affected by forest management and degradation globally. We reviewed empirically established dispersal ecology of saproxylic insects and fungi. We focused on direct studies (e.g., mark‐recapture, radiotelemetry), field experiments, and population genetic analyses. We found 2 somewhat opposite results. Based on direct methods and experiments, dispersal is limited to within a few kilometers, whereas genetic studies showed little genetic structure over tens of kilometers, which indicates long…
Science education and the “state of the world”: a programme of activities to enhance teacher’s perception of global problems and possible remedies
2003
A literatura sobre formação de professores de ciências não tem tratado suficientemente a situação do mundo quanto a uma percepção global de seus graves problemas atuais. O presente artigo consiste essencialmente de um programa de atividades a ser desenvolvido com professores em formação e em exercício, que visa favorecer uma reflexão coletiva e conscientização sobre essa problemática. Nesta perspectiva é apontado um conjunto de referências e questões para um debate fundamentado sobre vários dos fatores associados à degradação da vida e sobre possíveis medidas para o enfrentamento da emergência planetária. Investigações preliminares sobre a utilização do programa proposto têm revelado result…
Effect of different packaging methods on the free amino acid profiles of the deep-water rose shrimp (Parapenaeus longirostris) during frozen storage
2022
The composition of free amino acids (FAAs) in seafood products contributes to characterizing their flavor, as well as freshness and quality during storage. Deep-water rose shrimps (Parapenaues longirostris, Lucas, 1846) (DWRS) are being increasingly harvested in the Mediterranean Sea, and the captured specimens are quickly frozen onboard fishing trawlers to preserve freshness and post-harvest quality. Here, we quantified the FAA profiles of DWRS packaged using five methods: (1) 100% N2; (2) vacuum; (3) 50% N2 + 50% CO2; (4) commercial anhydrous sodium sulfite; and (5) air (control). All samples were quickly frozen at −35°C and stored for 12 months at −18°C. Arginine (661 mg/100 g), proline …
The early careers of the second generations: a double ethnic penalty?
2016
International audience; Young people from North African origin have greater difficulty in finding employment than their counterparts of French origin. And once they do manage to find employment, their jobs tend to be of lower quality. Thus they appear to suffer from a double penalty linked to their origins which, aggravated by the crisis, does not seem to abate over time.

Sense of quality of life and self-discrepancy - differences between social science and technology students
2020
The main purpose of the research is to determine personality predictors related to a new model of the sense of quality of life in a diverse group of students. The study is based on the self-discrepancy theory developed by Higgins, and the Personality and Axiological Model developed by Mróz. Method. Sixty four (64) pedagogy students and 62 electrical engineering students were the subjects of the research. The Adjective Check List test (ACL), the Modified Quality of Life Questionnaire as well as interview and observation were applied in the research. Results. Individuals with low self-discrepancy achieved significantly better results in Competences, Relationships, and Autonomy as part of the …
The Relationship between Knowing Sign Language and Quality of Life among Italian People Who Are Deaf: A Cross-Sectional Study
2023
Deafness is a medical condition with important relational implications. This condition could affect well-being and self-esteem and cause social anxiety. Sign language is not only a simple mimic but can be considered as a different kind of communication that could be protective for those who have learned it. However, some people do not use sign language because they think it can be marginalizing. The present study aimed to compare the quality of life (QoL) between people who learned Italian sign language as their first language with those who had never learned it or learned it later. This cross-sectional study involved 182 deaf Italian adults (70.3% females) who were recruited from Ente Nazi…
