Resumen tomado de la publicación Desarrollo y validación de la Escala de Valoración del Conflicto (WCAS). Antecedentes: en el contexto de la valoración cognitiva se ha desarrollado la escala de Evaluación del Conflicto en el Trabajo (WCAS) que permite evaluar el conflicto en términos de desafío y amenaza. Método: el Estudio 1 contó con 296 trabajadores con los que se puso a prueba la estructura factorial de la escala usando análisis factorial confirmatorio. En el Estudio 2, con 815 trabajadores, se realizó un análisis factorial confirmatorio multi-muestra, para la validación cruzada de los resultados. Resultados: los análisis confirman la validez de la escala y son consistentes con la clasi…

Resumen tomado de la publicación Versión española de la Escala Job Crafting. Antecedentes: una revisión de la literatura revela que no existen instrumentos de medida del job crafting en lengua española. Este artículo presenta la traducción, adaptación y validación de una escala para medir el comportamiento del job crafting (Spanish Job Crafting Scale -SJCS; Tims, Bakker, & Derks, 2012). Método: la escala fue aplicada a una muestra de 896 empleados (52,6% mujeres y 47,4% hombres). Se han testeado la fiabilidad y la validez factorial de un instrumento con 21 ítems. Resultados: después de realizar análisis confirmatorio (CFI= .858, TLI= .838, IFI= .860, RMSEA= .067), los resultados obtenidos c…
Desarrollo de una metodología de valoración objetiva de la recuperación de la marcha de personas con ictus basada en escalas clínicas y análisis ciné…
2014
La valoración objetiva de la marcha interesa en los ámbitos de la Medicina Física y Rehabilitación y la Medicina Legal. Los instrumentos para su evaluación son las escalas clínicas y las técnicas instrumentales, pero presentan limitaciones. El objetivo de este trabajo es desarrollar una metodología de valoración de la recuperación de la marcha de personas con ictus basado en escalas clínicas y análisis cinético, adecuada a las necesidades de la Rehabilitación y Medicina Legal. Se siguió una cohorte de treinta personas seis meses tras un ictus y se valoró la marcha, equilibrio y Actividades de la Vida Diaria (AVD) en ocho fases: estabilidad hemodinámica, bipedestación, inicio de la rehabilit…
Distance Learning with Hands-on Exercises : Physical Device vs. Simulator
2022
This Research to Practice Full Paper presents a comparison between a physical device and a simulator in a distance learning context. Programming embedded devices is very commonly taught using embedded hardware. One of the most used solutions is the Arduino microcontroller platform, which allows small embedded applications to be built and commanded in a programming language. However, there are some challenges in using physical devices for educational purposes. These challenges are particularly acute in distance learning or when the course needs to be scalable to a varying number of students. To address these challenges, we explored the potential of a simulator as a replacement for a physical…
Valutazione della Vulnerabilità a Scala Territoriale: Il Caso Studio di Caltabellotta (AG)
2017
I recenti studi nell’ambito della valutazione del rischio sismico a scala urbana-territoriale hanno fatto emergere la necessità di coniugare tecniche speditive e metodologie accurate, sia per il rilievo del costruito che per l’individuazione delle criticità e l’analisi strutturale. In quest’ambito, le schede CARTIS (schede di primo livello per la caratterizzazione tipologico-strutturale dei comparti urbani costituiti da edifici ordinari) rappresentano uno strumento in grado di fornire i dati necessari per la valutazione della vulnerabilità sismica con metodi tipologico-osservazionali. Nel presente lavoro si illustrano le metodologie adottate per la caratterizzazione costruttiva, il rilievo …
Gli affreschi provenienti dalle terme romane di Reggio Calabria. Dalla conoscenza al restauro
2023
The frescoes at marine thermae discovered in 1886 during the excavation of the small thermal complex dating between the 1th and 3rd century AD, and located on the seafront of Reggio Calabria, have been collected already collapsed. They are currently part of the permanent exhibition of the National Archaeological Museum of Reggio Calabria. This paper illustrates the results of the restoration intervention, carried out in the form of an educational activity in the context of an agreement signed between the MarRC and the University of Calabria, and the results of the diagnostic investigations carried out by the IPCF-CNR of Messina and the STEBICEF department of the University of Palermo.
Monitoring of erosion on two calanchi fronts – Northern Sicily (Italy)
2011
In the present research, two neighbouring calanchi fronts have been monitored by means of repeated readings on erosion pins, that were carried out between November 2006 and October 2008. During the monitoring period, a gauge station has been recording rainfalls, allowing us to compute the Rainfall-Runoff Erosivity Factor of the USLE model. The research highlighted: i) a general correspondence between rainfalls temporal trends and surface variation rhythms; ii) alternating erosion and deposition phases result in a retreat of the “calanchi” fronts.
HIGH-RESOLUTION SEISMIC SURVEY IN THE WESTERN CALABRIA AND EASTERN SICILY OFFSHORE: IMPLICATIONS WITH VERTICAL TECTONICS
2016
High-resolution seismic data acquired along the continental shelf/upper slope offshore of Capo Vaticano (western Calabria), Milazzo Promontory and Mt. Etna (eastern Sicily) allow to provide new insights on vertical mobility related to active tectonics. A number of depositional sequences bounded by unconformities or correlative para-conformities were recognized on Sparker profiles in the first 200-300 m below the sea-floor. The most recent sequence overlays a widespread erosional surface that ostensibly formed during the sea level stillstand of the Last Glacial Maximum (LGM), whereas a stack of depositional sequences, which are interpreted as representing the falling and low-stand systems tr…
Excess electronic recoil events in XENON1T
2020
We report results from searches for new physics with low-energy electronic recoil data recorded with the XENON1T detector. With an exposure of 0.65 t-y and an unprecedentedly low background rate of $76\pm2$ events/(t y keV) between 1 and 30 keV, the data enables sensitive searches for solar axions, an enhanced neutrino magnetic moment, and bosonic dark matter. An excess over known backgrounds is observed at low energies and most prominent between 2 and 3 keV. The solar axion model has a 3.4$\sigma$ significance, and a 3D 90% confidence surface is reported for axion couplings to electrons, photons, and nucleons. This surface is inscribed in the cuboid defined by $g_{ae}<3.8 \times 10^{-12}$,…
