Management of liver disease in Italy after one year of the SARS-CoV-2 pandemic: a web-based survey
2021
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)pandemic has severely limited the clinical activity of most hospitals around the world. A previous survey of the Italian Association for the Study of the Liver (AISF) has demonstrated a negative impact of the first pandemic wave on all inpatient and outpatient hepatologyactivities. Like other countries, Italy has subsequently experienced a second and third wave, which occurred in November 2020 and in March 2021 respectively. During the second and third wave many hospitals had already developed emergency management plans and improved knowledge on the management of mild-moderate COVID19 disease was available. However, it is unknown w…
Sourcing on the internet: Examining the relations among different phases of online inquiry
2021
This study examined students’ engagement in sourcing throughout online inquiry, that is, when they specified the information need, formulated search queries, evaluated online texts, and composed a written product. Participants were 167 upper secondary school students. Students completed an online inquiry task in a restricted online environment that utilized authentic online texts. Students’ prior topic knowledge and reading fluency was measured and controlled for in the analysis. The results showed that students engaged in sourcing even in the earliest phases of online inquiry. A sequential regression analysis indicated that the more frequently students engaged in sourcing in specifying the…
Personas mayores usuarias habituales de tecnologia de la información y la comunicacion: análisis del perfil
2015
Las Tecnologías de Comunicación e Información (TICs) son instrumentos básicos de participación social a lo largo del ciclo vital. Las personas mayores son una de las cohortes con mayor riesgo de exclusión social por la llamada brecha digital, pero cada vez más personas son usuarias habituales de estas tecnologías, mostrando características diferenciadoras de los perfiles más tradicionales de personas mayores. La presente investigación ha tenido como objetivo principal analizar las características que definen el perfil de personas mayores usuarias habituales de las TICs. Para ello ha sido necesario analizar el tipo de equipamiento que disponen, el uso y el nivel de importancia que le concede…
A Geometrical Channel Model for MIMO Mobile-to-Mobile Fading Channels in Cooperative Networks
2009
This paper deals with the modeling and analysis of narrowband multiple-input multiple-output (MIMO) mobile- to-mobile (M2M) fading channels in relay-based cooperative networks. Non-line-of-sight (NLOS) propagation conditions are assumed in the transmission links from the source mobile station to the destination mobile station via the mobile relay. A stochastic narrowband MIMO M2M reference channel model is derived from the geometrical three-ring scattering model, where it is assumed that an infinite number of local scatterers surround the source mobile station, the mobile relay, and the destination mobile station. The complex channel gains associated with the new reference channel model are…
A Geometrical Three-Ring-Based Model for MIMO Mobile-to-Mobile Fading Channels in Cooperative Networks
2011
Published version of an article published in the journal: Eurasip Journal on Advances in Signal Processing. Also available from the publisher at: http://dx.doi.org/10.1155/2011/892871. OA This paper deals with the modeling and analysis of narrowband multiple-input multiple-output (MIMO) mobile-to-mobile (M2M) fading channels in relay-based cooperative networks. In the transmission links from the source mobile station to the destination mobile station via the mobile relay, non-line-of-sight (NLOS) propagation conditions are taken into account. A stochastic narrowband MIMO M2M reference channel model is derived from the geometrical three-ring scattering model, where it is assumed that an infi…
Identity profiles and digital engagement among Finnish high school students
2018
Developing a stable personal identity is considered a more precarious task in today’s society than hitherto. Skilful digital engagement may, however, constitute a valuable asset in necessary identity exploration and commitment. Applying a person-oriented approach, we examined for the first time how identity profiles are associated with digital engagement, operationalized as digital competence, gaming seriousness, type of internet activity and excessive ICT use. After controlling for gender, life satisfaction and parental SES, this study of a Finnish high school sample (N = 932) revealed that adolescents with future commitments and some exploration of options (achievement, searching moratori…

Internet, Big data y nuevas tecnologías : repercusiones y respuestas del ordenamiento jurídico | Internet, Big data and new tecnologies: implications…
2019
Resumen: Cada uno de los movimientos que se suceden en la red genera información que se digitaliza en código binario y se almacena masivamente. La arbitrariedad con la que operan las grandes corporaciones del Big data así como la opacidad de los algoritmos empleados por la inteligencia artificial han dado origen a nuevas formas de vulneración de derechos, dónde la intimidad y el honor han resultado los primeros damnificados. Este escenario requiere un replanteamiento de conceptos jurídicos como estado o vida privada que han cobrado nuevos significados y demandan construcciones jurídicas capaces de reforzar el control sobre nuestros derechos más fundamentales.

Distributed radio map reconstruction for 5G automotive
2018
Se espera que los mapas de entorno radio sean una herramienta esencial para la optimización y gestión de recursos del 5G en vehículos. En este trabajo, consideramos el problema de la reconstrucción del mapa de entorno radio utilizando una red de sensores inalámbricos formada por nodos sensores en vehículos, nodos de acceso de una infraestructura de ciudad inteligente, etc. Debido a las limitaciones de recursos en las redes de sensores, es crucial seleccionar un pequeño número de mediciones de los sensores para reconstruir el campo. En este contexto, presentamos un novedoso algoritmo distribuido basado en el método de regresión Kriging para la reconstrucción del mapa de entorno radio en térm…
