De las aulas universitarias a la red. Un proyecto innovador aplicado al aprendizaje y difusión de la literatura catalana barroca
2017
[EN] This paper focuses on the description and analysis of an innovative educational experience in the field of the Baroque Catalan Literature. This experience, which has recently been implemented as a pilot test in universities thanks to the a project of innovative teaching, concentrates on the use of tecnological resources and the development of an initial project of Transmedia Storytelling to foster the motivation of students and generate a more meaningful learning. This case study is grounded in the implementation of the resources and active methodologies of the course on Early Modern Catalan Literature, traditionally based on conventional educational strategies and despised by the hist…
Spatio-temporal perturbation of the dynamics of the ferroin catalyzed Belousov-Zhabotinsky reaction in a batch reactor caused by sodium dodecyl sulfa…
2008
The effects of the anionic surfactant sodium dodecyl sulfate (SDS) on the spatio-temporal and temporal dynamics of the ferroin-catalyzed Belousov-Zhabotinsky (BZ) reaction have been studied over a wide surfactant concentration range. For the first time, investigations were performed also for unstirred systems. The presence of SDS in the reaction mixture influences the oscillatory parameters to an extent that significantly depends on the surfactant concentration. The trend of the wave speed v upon the increasing amount of SDS was found to have a maximum at [SDS] = 0.075 mol dm (-3) ( v = 0.071 mm s (-1)), after which the speed decreased to 0.043 mm s (-1) at [SDS] = 0.5 mol dm (-3), which is…
Sida y prisión
2002
La relación entre droga y delincuencia hace que Instituciones Penitenciarias se con¬centren numerosas personas con antecedentes de uso de droga inyectadas (UDIs), principal práctica de riesgo para transmisión de la infección. Esta misma concentra¬ción sin embargo es una buena oportunidad de intervención terapéutica. En este trabajo se expone la situación de la infección por VlH/Sida en lnstituciones Penitenciarias(evolución y tratamiento) y los principales Programas que se aplican en la actualidad en beneficio de una prevención de la enfermedad, fundamentalmente dirigidos a la educación sexual y deshabituación del consumo de drogas, dentro del objetivo general de disminución de riesgos.

However, their exact regulation and effects in periodontitis are not known. The aim of this in-vitro study was to investigate the effect of microbial and inflammatory insults on the GHS-R1a expression in human osteoblast-like cells. MG-63 cells were exposed to in…
Adoption of a COVID-19 Contact Tracing App Among Older Internet Users in Finland
2022
The outbreak of the COVID-19 pandemic created an unequal need for limiting physical contacts and tracing possible exposures to a novel coronavirus. Smartphone-based contact tracing applications (CTAs) were presented as a vehicle for stopping virus transmission chains and supporting the work of contact tracing teams. In this study, older adults’ adoption of a CTA was studied using socioeconomic background factors, satisfaction with health, and the measure of digital activity as predictors. The data were drawn from a larger questionnaire survey targeted at older internet users. A subsample of older Finnish internet users (N = 723) was analyzed using a logistic regression model. Results showed…
Pornografía infantil: cambios en las formas de obtención y distribución
2017
RESUMEN: El objetivo de este estudio es sintetizar el conocimiento científico sobre los principales mecanismos empleados para la obtención y distribución de pornografía infantil a lo largo de la historia. Para ello, se ha realizado una búsqueda exhaustiva de los trabajos publicados hasta 2016, siendo seleccionados un total de 37. Los resultados obtenidos permiten diferenciar cuatro grandes etapas del tráfico de pornografía infantil (comercial, informatizada, Internet, oculta), en las que los consumidores han migrado hacia tecnologías que les resultan más atractivas y adecuadas para sus fines (Deep Web y redes p2p sin filtro). Sin embargo, un sistema descentralizado como Internet impide la a…

Children as social actors negotiating their privacy in the digital commercial context
2023
This study advances research on children’s negotiation of online commercial privacy by identifying an act of digital agency by children that may serve their current needs but can also impact children negatively. Secondly, it identifies certain factors children consider while evaluating the trustworthiness of apps and websites before disclosing information online. Eight focus group discussions with children (13–16 years) in Finland’s capital region are analysed using thematic analysis. Our findings highlight that while children’s digital literacy education is needed, ensuring that education translates to children’s online practices is also essential. We also recommend increasing corporations…
