Mappings of finite distortion : boundary extensions in uniform domains
2015
In this paper, we consider mappings on uniform domains with exponentially integrable distortion whose Jacobian determinants are integrable. We show that such mappings can be extended to the boundary and moreover these extensions are exponentially integrable with quantitative bounds. This extends previous results of Chang and Marshall on analytic functions, Poggi-Corradini and Rajala and Akkinen and Rajala on mappings of bounded and finite distortion.
Dal mare al museo. Il recupero di uno scheletro di stenella striata, Stenella coeruleoalba (Meyen 1833)
2022
In 2021, the Museum of Zoology “P. Doderlein” of the University of Palermo acquired a new specimen, the complete skeleton of Stenella coeruleoalba, a striped dolphin stranded in 2018 in Marinella di Selinunte, Castelvetrano (Sicily, Southern Italy). The project herein described is the result of a collaboration among the Bio-Reconstruction Laboratory of the IAS-CNR of Capo Granitola, the IZS of Palermo, the company Naturaliter and the Museum of Zoology “P. Doderlein”. In Natural History Museums, cetaceans are an excellent tool to facilitate scientific dissemination aimed at the conservation of marine biodiversity. The work herein described is presented as an example of good practices in reco…
Employment and earnings trajectories before and after sickness absence due to major depressive disorder: a nationwide case-control study.
2020
ObjectivesTo examine employment and earnings trajectories before and after the first sickness absence period due to major depressive disorder (MDD).MethodsAll individuals (n=158 813) in Finland who had a first sickness absence period (lasting longer than 9 days) due to MDD between 2005 and 2015 were matched with one randomly selected individual of the same age and gender with no history of MDD. Employment status and earnings were measured using register-based data annually from 2005 to 2015. Generalised estimating equations were used to examine the trajectories of employment and earnings before and after MDD diagnosis in men and women separately.ResultsSickness absence due to MDD was associ…
Intermediate Isolation System for the seismic retrofit of existing masonry buildings
2022
This paper deals with the potentials of Intermediate Isolation Systems (IIS) for retrofitting masonry buildings by means of a vertical extension, isolated at its base, and realized on the rooftop of the existing structure. By carefully defining the dynamic properties of the superstructure and isolation system, in previous papers the authors have demonstrated that this passive technique is able to reduce a priori the seismic demand on the existing building. For this reason, the non-linear behavior has been only assumed for the isolation system, with the masonry structure in the elastic field. This result has been validated by carrying out spectrum-compatible time history analyses on the 3D F…
Whole class interaction in the adult L2-classroom : The case of Swedish for immigrants
2019
This article focuses on verbal interaction in whole class teaching in second language education for adults in Sweden. The article draws on theories treating language as multiple resources that are situated and embedded in material life, and including complex and diverse linguistic, semiotic, physical material and social resources. The material for the article was created in a project based in linguistic ethnography in the form of an action research project, including two municipal Swedish for Immigrants (SFI) schools. The interaction patterns that occurred challenged students’ language proficiency in ways that stimulated meaning negotiation through what we call extended interactions. This s…
Archaeometric Characterisation of Decorated Pottery from the Archaeological Site of Villa dei Quintili (Rome, Italy): Preliminary Study
2019
This work focused on the study of decorated pottery dated back to the 16th century from the Roman archaeological site of Villa dei Quintili, a monumental complex located in the south-eastern part of Rome (Italy). A minero-petrographic and geochemical study was undertaken to analyse five archaeological samples in order to define textural features and raw materials used for their production, along with the chemical and physical composition of the superficial decorative glazed coatings. For this purpose, different analytical methods were used, such as polarising optical microscope (POM), X-ray diffraction (XRD), micro-Raman spectroscopy, X-Ray fluorescence (XRF), and electron microprobe analys…
El ejercicio físico y la promoción de la salud en la infancia y la juventud
1992
SummaryThe «new health consciousness» that emerged in the developing countries in the 70s and 80s, has contributed to consider exercise as an element of health promotion. But it can establish simplistic relationships between exercise and health, particularly critical for professionals who develop promotion programmes. In this paper, five problematic aspects linked, to exercise and health relationships both in children and youngsters, are discussed and should be taken into account when promoting health programmes. We refer to: 1) the problematic role of exercise in health promotion and in physical education curriculum as an area of privileged action in children and youngsters; 2) the automat…
Generation of programmable 3D optical vortex structures through devil’s vortex-lens arrays
2013
Different spatial distributions of optical vortices have been generated and characterized by implementing arrays of devil's vortex lenses in a reconfigurable spatial light modulator. A simple design procedure assigns the preferred position and topological charge value to each vortex in the structure, tuning the desired angular momentum. Distributions with charges and momenta of the opposite sign have been experimentally demonstrated. The angular velocity exhibited by the phase distribution around the focal plane has been visualized, showing an excellent agreement with the simulations. The practical limits of the method, with interest for applications involving particle transfer and manipula…
The Spanish Version of the Empathy Questionnaire (EmQue): Evidence for Longitudinal Measurement Invariance and Relationship With Emotional Regulation
2018
Research Findings: Empathy, or the ability to understand what others are thinking or feeling, can be observed in early developmental stages. The purpose of this study was to validate the Spanish ve...
Development of Burnout Syndrome in Non-university Teachers: Influence of Demand and Resource Variables.
2021
Psychosocial risks at work are an important occupational problem since they can have an impact on workers' health, productivity, absenteeism, and company profits. Among their consequences, burnout stands out for its prevalence and associated consequences. This problem is particularly noteworthy in the case of teachers. The aim of the study was to analyze the influence of some psychosocial factors (demand and resource variables) and risks in burnout development, taking into consideration the levels of burnout according to the Spanish Burnout Inventory (SBI). This paper contributes to advancing knowledge on this issue by analyzing the influence of work characteristics and personal characteris…
