Prometeo genetista. Profitti delle tecniche e metafore della scienza
2016
Il saggio di Claude Calame affronta una tematica di grande rilievo scientifico, ossia il confronto tra il valore epistemologico e sociale dell'uso delle arti tecniche nell'antica Grecia e il valore epistemologico del linguaggio della scienza moderna in particolare applicato all'ambito della genetica e delle moderne biotecnologie e scienze di laboratorio. Lo spunto del confronto è offerto dall'analisi storico-culturale e antropologica del mito di Prometeo, come è stato diversamente declinato dai vari autori dell'antichità classica, a partire da Esiodo sino a Platone, passando per l'autore del dramma "Prometeo incatenato". In una prospettiva di indagine antropopoietica, le arti tecniche perme…
Are quality management practices enough to improve process innovation?
2015
The popularity of quality management as a system for continuous improvement has not been accompanied by deep theoretical understanding of its effects on process innovation. In this work, the resource-based view serves as the basis for the construction of a model designed to explain the effects of quality management practices (QMP) on process innovation performance and the mediating role of dynamic capabilities in this relationship. The empirical data were analysed using the structural equation modelling technique by examining 6 competing models that represent full, partial mediation and non-mediation relationships on a sample of 550 Spanish industrial companies. The findings indicate that t…
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…
Prenatal thyroid hormones accelerate postnatal growth and telomere shortening in wild great tits
2021
AbstractEarly-life environment is known to affect later-life health and disease, which could be mediated by the early-life programming of telomere length, a key hallmark of ageing. According to thefetal programming of telomere biology hypothesis, variation in prenatal exposure to hormones is likely to influence telomere length. Yet the contribution of key metabolic hormones,i.e. thyroid hormones (THs), has been largely ignored. We recently showed that in contrast to predictions, exposure to elevated prenatal THs increased postnatal telomere length in wild collared flycatchers, but the generality of such effect, its underlying proximate mechanisms and consequences on survival have not been i…
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,…
Group‐based instant messaging in Finnish residential elder care work : taming the technology or vice versa?
2022
As new communication technologies become embedded in care work, there is a need to understand how they affect its temporal order. This article analyses group-based mobile instant messaging (IM) in residential elder care work in Finland. The article asks (i) how care workers use group-based messaging for work; and (ii) how they negotiate the rules for its use. Theoretically, the article draws on science and technology studies focusing on ‘taming’ and ‘unleashing’ (Pols, 2017), and temporality (Wajcman, 2008). Analysis is based on a qualitative interview study of care workers and nurses (n = 25) conducted in 2018. The results showed how the time-shifting functionality of IM allows employees t…
The contribution of action research to policy learning: The case of Gipuzkoa Sarean
2014
Published version of an article in the journal: International Journal of Action Research. Also available from the publisher at: http://dx.doi.org/10.1688/IJAR-2014-02-Karlsen This article is about a six year policy learning process named Gipuzkoa Sarean in the Basque province of Gipuzkoa. In the article we reflect on how action research contributed to policy learning. The process consists of three stages: 2009-2011: Initiation of the project and development of a work method; 2011-2013: Government learning and organisational change; 2013-2014: Social learning and the shift to a new approach to territorial development. For each stage we describe the background and main goal of the research pr…
