The usage of Twitter from the Spanish media during the elections
2018
Los medios de comunicación tradic ionales han adoptado Twitter c omo otro canal por el que difundir su información y llegar hasta las audiencias digit ales. Este estudio tiene como objetivo analizar las características de los tuits publicados por los me dios españoles durante doce meses en los que se producen dos procesos electorales, para comprobar las di ferencias en la utilización de esta plataforma según el contenido de la cobertura y la fase en que se publica. La investigación se fundamenta en una metodología cua ntitativa, en la que se implem enta un análisis de contenido computarizado de las publicacione s en Twitter que hacen los dis tintos tipos de medios entre 2015 y 2016. Los res…
Rhetoric and Pragmatics: Suggestions for a Fruitful Dialogue
2013
The aim of this paper is to show that classical rhetoric can provide valuable insights in the contemporary debate in pragmatics. This is especially true for Aristotelian rhetoric, due to its philosophical approach. In the first part of the paper, I discusses the conditions under which ancient rhetoric can be a real partner of current pragmatics: (1) rhetoric must be understood as a type of knowledge (a techne) and not as a “jumbles of techniques”; (2) we need to consider persuasion as an anthropological feature and not only as a specific case of communication; (3) we should not exclude truth from the rhetorical field. The second part of the paper focuses on what can be considered the basic …
Methodological Problems in RCTs on IBD
2012
Abstract: Randomized controlled trials (RCTs) are the gold standard method for developing evidence-based medicine in inflammatory bowel disease (IBD). Methodological problems in RCTs in IBD concern different aspects such as the definition of the study population due to the extreme variability of patients with IBD, the indices of disease activity, a clearly defined outcome, the environmental risk factors (i.e smoking behaviour) that may influence the randomization, the heterogeneous placebo rate of remission and the different statistical methods used to analyze the results. It is important that trials are designed efficiently, done well and complement clinical practice with a careful subject…
Logos, Pathos and Ethos in Ackroyd's Plato's Papers via an Interdisciplinary Psycho-philosophical Approach
2014
Abstract The present moral crisis of humanity will be closely considered in Ackroyd's Plato's Papers via Riemann's Theorem of Earth Mapping, Kelly's Personal Construct theory and Plato's Idea of the Third Man with a view to showing that only the generally assumed relationship between logos and ethos could rescue the mentality of the entire world and retrieve temporality and morality. For this approach to be successfully turned to good account the Aristotelian concepts of Logos (the thinking part of the intellect) mediating with Pathos (the feeling self) through the actions of his acting self, the personal Ethos, will be employed in relation to Ackroyd's character, Plato, the philosopher-ora…
Un'autoetnografia per immagini
2020
Lo studio propone una riflessione geografica sulla fotografia (sui suoi usi e sui suoi sviluppi) in relazione a varie forme di spazialità. Attraverso l'analisi di alcune immagini sul Social Network Instagram viene presentata un'etnografia di tipo riflessivo utile a definire e discutere alcuni aspetti espistemologici della disciplina geografica, quali la metodologia da utilizzare, il posizionamento del ricercatore sul campo e i suoi oggetti di conoscenza e d'indagine scientifica. The study proposes a geographical reflection on photography (on its uses and its developments) in relation to various forms of spatiality. Through the analysis of some images on the Instagram Social Network, a refle…
Shrinkage and spectral filtering of correlation matrices: A comparison via the Kullback-Leibler distance
2007
The problem of filtering information from large correlation matrices is of great importance in many applications. We have recently proposed the use of the Kullback-Leibler distance to measure the performance of filtering algorithms in recovering the underlying correlation matrix when the variables are described by a multivariate Gaussian distribution. Here we use the Kullback-Leibler distance to investigate the performance of filtering methods based on Random Matrix Theory and on the shrinkage technique. We also present some results on the application of the Kullback-Leibler distance to multivariate data which are non Gaussian distributed.
Nonlocal symmetry for QED
1993
We demonstrate that QED exhibits a previously unobserved noncovariant, nonlocal symmetry. Some consequences are discussed.
Teacher professional development in the context of the “Open Discovery of STEM laboratories” project: Is the MOOC methodology suitable for teaching p…
2020
Abstract The “Open Discovery of STEM Laboratories” (ODL) project, funded by the European Erasmus+ KA2 program, was aimed at introducing the use of MOOCs in school curricula. In particular, it fostered teacher collaboration in creating and using micro-MOOCs for the inclusion of STEM (Science, Technology, Engineering and Mathematics) online remote or virtual laboratories in the everyday teaching practice. The project focused on teachers, educators and curriculum designers with the aim to strengthen their profile by supporting them to deliver high quality teaching practices and to adopt new methods and tools. Thanks to the project, in service and pre-service teachers had the opportunity to ext…
