Comunicació 2.0 i gènere
2009
Internet ha capgirat les formes de comunicació i d’intercanvi d’informació entre les persones: les receptores en el procés comunicatiu són ara també emissores. La conjunció d’aquesta particularitat amb l’aparició i ús d’algunes eines de comunicació (fàcils d’usar i bàsicament gratuïtes) permet parlar d’un fenomen social de gran abast: la comunicació 2.0. Aquest article analitza algunes de les característiques d’aquesta classe d’interacció i centra l’interés de forma particular en certes iniciatives que tenen com a epicentre les qüestions de gènere. La comunicació 2.0 permet la participació activa i directa en el procés, obert i col·laboratiu, de construcció de la identitat pròpia. Així mate…
« Thyroid diseases and Controversies »
2022
The topic of the presentation is related to thyroid controversies online, specifically the Levothyrox controversy that took place in France in 2017. The objective of this work aims at performing a quantitative content analysis of online messages in order to understand how digital tools and technologies such as an online forum, shape and impact controversies.
Delphi study for the design and validation of a questionnaire about digital competences in higher education
2016
The study of digital competence remains an issue of interest for both the scientific community and the supranational political agenda. This study uses the Delphi method to validate the design of a questionnaire to determine the perceived importance of digital competence in higher education. The questionnaire was constructed from different framework documents in digital competence standards (NETS, ACLR, UNESCO). The triangulation of non-parametric techniques made it possible to consolidate the results obtained through the Delphi panel, the suitability of which was highlighted through the expert competence index (K). The resulting questionnaire emerges as a good tool for undertaking future na…
La competencia TIC en el nuevo currículo peruano desde la perspectiva de la educación mediática
2017
El 2017 empieza a implementarse en el Perú un nuevo currículo para la edu-cación obligatoria. Entre otras novedades, esta norma desarrolla una com-petencia específica sobre las Tecnologías de la Información y la Comunica-ción (TIC). Para abrir el debate e introducir otros marcos de referencia que enriquezcan el análisis, este artículopresenta y analiza la denominada com-petencia TIC desde la perspectiva de la educación mediática. Concluimos que, aunque no se enuncie una competencia mediáticacomo tal, algunas de sus propuestas conceptuales están presentes de forma diseminada, lo que presenta una oportunidad para el desarrolloinicialde la educación me-diática en el contexto peruano. In 2017, …
Optimisation of direct digital frequency synthesisers based on CORDIC
2001
Methods to simplify digital frequency synthesizers based on the co-ordinate rotation digital computer (CORDIC) algorithm are presented. Application of these methods leads to performance enhancement, compared with the topologies previously proposed in the literature. For a given output precision, hardware resources are reduced and spur-free dynamic range is increased.
New digital trends in current architecture. A comprehensive critical examination
2017
The research presented is about digital revolution in architecture, which has contributed to the birth of new figurative trends. The work was conducted through the definition of a framework to identify and classify architectural design elements that should be attributed to the methods and techniques of design computing, then applied to sixty prominent recent architectures which are acknowledged products of digital means. The early results suggest that a new era is coming, where the conceptual starting point of designers is often born in the digital space, taking advantage of the augmented representation skills to control and manipulate form. We will also do an overview of these new architec…
Information retrieval in digital documents : a variation patterns of procedural execution
2013
The research activity of information on the internet has become common in our daily life. Despite this fact, it still raises many problems for the user who does not find the information they want or is lost to the amount of information available. This study aims at testing a new patented preview device, enabling users to browse and view pages in depth. The task is to find a target apartment with one or more specific criteria in a real estate agency designed website. Several conditions were tested. The “usual” condition with the classic search features, page by page, the other "transparent" condition which enables you to preview selected pages and select only relevant pages. We are intereste…
L’excursus evolutivo fra l’OCSE e l’Unione Europea
2023
Il contributo esamina Il ruolo svolto dall’OCSE e dall’Unione Europea nello sviluppo di possibili modelli di tassazione dell'econima digitale, distinguendo tre fasi. La prima è stata definita come fase della “neutralità”, poiché l’economia digitale è stata considerata alla stregua dell’economia tradizionale e, pertanto, l’approccio fiscale nei suoi confronti doveva essere neutrale, cioè non diverso da quello che ha storicamente caratterizzato l’economia tradizionale a livello internazionale. La seconda è stata definita come fase del “contrasto” poiché, muovendo dalla consapevolezza che l’applicazione degli strumenti della digitalizzazione all’economia tradizionale aveva consentito alle impr…
Digital education, geography and multidisciplinarity: Themes, methods and critical issues
2023
<abstract> <p>The article is the Editorial of the Special Issue "Digital Education, Geography and Multidisciplinarity: Themes, Methods and Critical Issues". It explores some fundamental and theoretical issues on the interrelated subjects of digital education, geography and multidisciplinarity. More in particular, the article takes into account the manner in which this Special Issue of AIMS Geosciences reflects on links between the teaching/learning of geography (at any school/university level) and the digital world in a multidisciplinary perspective. That includes both the critical issues and the advantages in terms of sustainability and greater awareness of geographical phenome…
32×32 winner-take-all matrix with single winner selection
2010
A 32 × 32 winner-take-all (WTA) matrix with single winner selection is introduced. A high-resolution gain-boosted regulated-cascode WTA circuit is used in a first competition stage. Because of the large number of competing cells the possibility of a multiple winners situation arises. A single winner is obtained by means of a digital inhibitory circuit following each WTA analogue amplifier. Simulations show that this mixed analogue-digital circuit achieves its objective with a current resolution of approximately 10 nA (0.8% of the maximum input current in the simulated case). A time response of ?s can be achieved.
