Coneixement, error i ignorància. Una apologia (parcial) de l'escepticisme
2015
Què és pitjor, l'error o la ignorància? En aquest aricle es compara l'ignorant que sap que ignora amb l'escèptic i es contraposen a qui està convençut. El convençut no té cap motiu per indagar, i si està errat romandrà en l'error.
El coneixement humà I [Pròleg]
1985
El coneixement humà. El seu abast i els seus límits està considerada com la darrera obra sistemàtica de filosofia de B. Russell; ·fou publicada el 1948, quan Russell tenia 76 anys, just el mateix any que, a força de nedar, va salvar la seua vida d'un accident d'avió precipitat al mar. Posteriorment a aquesta data, Russell publica obres de temes d'allò més divers, entre les quals cal destacar una de filosòficament important: My philosophical development (1959). L'obra, però, no intenta d'ésser un resum final o sistema del pensament de l'autor. En primer lloc, perquè el filòsof anglès la va escriure com una obra més, com el resultat de les seues darreres investigacions, que afegien als estudi…
Operator martingale decomposition and the Radon-Nikodym property in Banach spaces
2010
Abstract We consider submartingales and uniform amarts of maps acting between a Banach lattice and a Banach lattice or a Banach space. In this measure-free setting of martingale theory, it is known that a Banach space Y has the Radon–Nikodým property if and only if every uniformly norm bounded martingale defined on the Chaney–Schaefer l-tensor product E ⊗ ˜ l Y , where E is a suitable Banach lattice, is norm convergent. We present applications of this result. Firstly, an analogues characterization for Banach lattices Y with the Radon–Nikodým property is given in terms of a suitable set of submartingales (supermartingales) on E ⊗ ˜ l Y . Secondly, we derive a Riesz decomposition for uniform …
Absorption of oxybutynin from vaginal inserts: drug blood levels and the response of the rabbit bladder.
2000
Abstract Objectives. Oxybutynin has been used for treatment of urge urinary incontinence for more than 20 years. However, one of the major problems with its use is uncomfortable anticholinergic side effects that can lead to discontinuation of treatment. Alternative forms of drug administration may reduce side effects and thus improve patient compliance. Methods. A cylinder-shaped, curved silicone elastomer insert containing oxybutynin was anchored in the vagina of female rabbits. The inserts were designed to release oxybutynin at rates of 0.5, 1.0, and 5.0 mg/day, respectively. Blood drug and metabolite levels were monitored for 1 to 7 days and cystometry was carried out after 7 days of tre…
Knowledge transfer and university-business relations: Current trends in research
2017
Purpose: To identify the current research trends regarding knowledge transfer and the university-business relationships during the period 2013-2016 in the journals indexed in ISI Web of Knowledge. Design/methodology: In order to fulfill the research objective, a bibliographic search was conducted using the Pro-KnowC (Knowledge Development Process-Constructivist) tool, developed by LabMCDA (Laboratory of Multicriteria Methodologies to Support Constructivist Decision-Making). Findings: As a result, a total of 122 articles were identified, classified into 4 separate lines of research, in which the most discussed topic was the economic impact of university-business relations, appearing in a tot…
Escenarios tecnológicos con dispositivos móviles para la acción educativa. Tendencias y vínculos con la imagen
2021
Presentamos un acercamiento a los escenarios educativos con TIC en la actualidad, en concreto tecnologías portables y modelos pedagógicos de colaboración complementarios a ellas, propios del constructivismo. La capacidad de aprendizaje que estos pueden llegar a suscitar, en cualquier momento y en cualquier lugar, refleja una realidad tangible en nuestra sociedad móvil. Nos referimos a los PLE Entornos Personales de Aprendizaje, BYOD Bring Your Own Device, la Gamificación, Flipped Classroom y la Realidad Aumentada y la Realidad Virtual. Se realiza una revisión de literatura de propuestas pedagógicas destacables, a través de algunos de los principales actores que las abordan en España. En cad…
Técnicas de análisis de posproceso en resonancia magnetica parael estudio de la conectividad cerebral
2011
Brain connectivity is a key concept for understanding brain function. Current methods to detect and quantify different types of connectivity with neuroimaging techniques are fundamental for understanding the pathophysiology of many neurologic and psychiatric disorders. This article aims to present a critical review of the magnetic resonance imaging techniques used to measure brain connectivity within the context of the Human Connectome Project. We review techniques used to measure: a) structural connectivity b) functional connectivity (main component analysis, independent component analysis, seed voxel, meta-analysis), and c) effective connectivity (psychophysiological interactions, causal …
Structure of longitudinal chromomagnetic fields in high energy collisions
2014
We compute expectation values of spatial Wilson loops in the forward light cone of high-energy collisions. We consider ensembles of gauge field configurations generated from a classical Gaussian effective action as well as solutions of high-energy renormalization group evolution with fixed and running coupling. The initial fields correspond to a color field condensate exhibiting domain-like structure over distance scales of order the saturation scale. At later times universal scaling emerges at large distances for all ensembles, with a nontrivial critical exponent. Finally, we compare the results for the Wilson loop to the two-point correlator of magnetic fields.
«Bella mia fiamma, addio / Resta, o cara» tra Jommelli e Mozart: osservazioni e ipotesi sull’aria K. 528
2012
Mozart wrote the scena and aria K. 528 in Prague in 1787 for the singer Josepha Duschek. As previously known, this wonderful page is based on a text taken from “Cerere placata”, a “festa teatrale” created in Naples in 1772 by the man of letters and scientist Michele Sarcone and the renowned “maestro di cappella” Niccolò Jommelli to celebrate the birth of the first daughter of king Ferdinand IV of Bourbon. The article reconstructs in detail the circumstances of the Neapolitan performance, and shows that Jommelli’s setting of Titano’s recitative and aria “Bella mia fiamma, addio” / “Resta, o cara; acerba morte” enjoyed a large success and circulated as an autonomous piece. A comparison betwee…
