Design of mobile phones for older adults : An empirical analysis of design guidelines and checklists for feature phones and smartphones
2017
Design guidelines and checklists are suggested as a useful tool in the development and evaluation of interface design of mobile phones for older adults. Given the intense evolution of mobile phone design, understanding how the design guidelines and checklists have taken into account the advances in mobile phone usability for older adults is important for their correct application and future development. Thus, this study explores the usability dimensions of mobile phone design for older adults and the related changes in terms of time and the type of device (feature phones vs. smartphones) based on an expert coding of the eight mobile phone design guidelines and checklists for older adults pu…
Reducing Relationship Conflict in Virtual Teams With Diversity Faultlines: The Effect of an Online Affect Management Intervention on the Rate of Grow…
2020
The aim of this study was to analyze the effect of an online affect management intervention on relationship conflict through the rate of growth of team resilience in virtual teams with diversity faultlines. Fifty-two 4-person teams participated in a randomized controlled trial design with repeated measures (i.e., three measurement occasions). Teams were randomly assigned to either an intervention designed to help them manage emotions in virtual teams or a control condition. Our findings showed that affect management can reduce the level of relationship conflict in virtual teams with diversity faultlines and that this effect can be explained by the pattern of change in team resilience in re…
Teoría de la educación : educación y cultura en la sociedad de la información
2016
Las nuevas tecnologías de la información y la comunicación han construido un nuevo contexto: la sociedad de la información, en la que la escuela sufrirá necesariamente cambios importantes. La integración de estas nuevas tecnologías en la educación será adecuada si se realiza desde una perspectiva pedagógica activa y constructiva. En esa dinámica hay una serie de factores muy importantes para una integración eficaz: el apoyo institucional y el desarrollo de políticas pertinentes, lo que comporta dotación de infraestructuras y formación de los profesores, el apoyo de los equipos directivos de los centros, y el desarrollo de modelos de evaluación coherentes. The information and communication n…
Protección de la infancia y nuevas tecnologias de la comunicación : el código PEGI de regulación de los videojuegos y juegos on-line
2008
Monográfico con el título: 'Videojuegos: una herramienta en el proceso educativo del 'Homo Digitalis''. Resumen basado en el de la publicación Se dice que el futuro de un pueblo reside en sus hijos, y no sólo porque ellos son el futuro, sino porque este es mejor si protege y educa bien a sus niños. Ya en 1959 la Organización de las Naciones Unidas redactó diez principios en la Declaración de los Derechos del Niño. El segundo de estos principios afirma que 'el niño gozará de una protección especial para que pueda desarrollarse física, mental, moral, espiritual y socialmente'. En el siglo XXI, en un contexto de sociedad del conocimiento muy diferente al de 1959, el derecho a la protección deb…
Performance of Lead-Acid Batteries with Nanostructured Electrodes at Different Temperature
2018
In this work we present innovative lead-acid batteries with nanostructured electrodes, which are cycled in a wide range of temperatures typically of lead-acid commercial batteries (EN 61427-1: 2013). In comparison to parameters usually used to commercial batteries, much more stressful conditions in terms of cut-off, charge/discharge rate and discharge were imposed.
High-Performance Lead-Acid Batteries Enabled by Pb and PbO2 Nanostructured Electrodes: Effect of Operating Temperature
2021
Lead-acid batteries are now widely used for energy storage, as result of an established and reliable technology. In the last decade, several studies have been carried out to improve the performance of this type of batteries, with the main objective to replace the conventional plates with innovative electrodes with improved stability, increased capacity and a larger active surface. Such studies ultimately aim to improve the kinetics of electrochemical conversion reactions at the electrode-solution interface and to guarantee a good electrical continuity during the repeated charge/discharge cycles. To achieve these objectives, our contribution focuses on the employment of nanostructured electr…
On Temporal Aspects in Cross-Cultural e-Collaboration Between Finland and Japan Research Teams
2018
Time is an essential dimension in cross-cultural e-collaboration among research project teams. Understanding temporal aspects and project dynamics in cross-cultural research e-collaboration and related processes can improve team members' skills in cross-cultural communication and increase their cultural competence. The present case cultures are Finnish and Japanese, and the case universities are the University of Jyväskylä (Finland) and Keio University (Japan). Three issues are addressed in this article. First, cultural dimensions and time models in the cross-cultural e-collaboration context are discussed. Second, temporal aspects related to e-collaboration activities are introduced. Third,…
The role of age and digital competence on the use of online health and social care services: A cross-sectional population-based survey
2022
Objective Online health and social care services are getting widespread which increases the risk that less advantaged groups may not be able to access these services resulting in digital exclusion. We examined the combined effects of age and digital competence on the use of online health and social care services. Methods We used a large representative population-based sample of 4495 respondents from Finland. Paper-based self-assessment questionnaire with an online response option was mailed to participants. The associations were analyzed using survey weighted logistic regression, exploring potential non-linear effects of age and controlling for potential sex differences. Results Higher age,…
A Particular Focus on the Prevalence of α- and β-Thalassemia in Western Sicilian Population from Trapani Province in the COVID-19 Era
2023
Thalassemia is a Mendelian inherited blood disease caused by α- and β-globin gene mutations, known as one of the major health problems of Mediterranean populations. Here, we examined the distribution of α- and β-globin gene defects in the Trapani province population. A total of 2,401 individuals from Trapani province were enrolled from January 2007 to December 2021, and routine methodologies were used for detecting the α- and β-globin genic variants. Appropriate analysis was also performed. Eight mutations in the α globin gene showed the highest frequency in the sample studied; three of these genetic variants represented the 94% of the total α-th…
On the Choice of the Extracellular Vesicles for Therapeutic Purposes
2019
Extracellular vesicles (EVs) are lipid membrane vesicles released by all human cells and are widely recognized to be involved in many cellular processes, both in physiological and pathological conditions. They are mediators of cell-cell communication, at both paracrine and systemic levels, and therefore they are active players in cell differentiation, tissue homeostasis, and organ remodeling. Due to their ability to serve as a cargo for proteins, lipids, and nucleic acids, which often reflects the cellular source, they should be considered the future of the natural nanodelivery of bio-compounds. To date, natural nanovesicles, such as exosomes, have been shown to represent a source of diseas…
