Docència i lliure accés: l'Open Course Ware de la Universitat de València
2008
En este artículo presentamos la Oficina OCW de la Universitat de València atendiendo al contexto general de aparición y sus características específicas. En primer lugar, contextualizamos el Open Course Ware en el ámbito de los movimientos Open y repasamos algunas de sus iniciativas. Después nos centramos en la caracterización de los usuarios/destinatarios prototípicos del OCW como “nativos digitales”, atendiendo a la distinción de dos modelos epistemológicos: la inteligencia colectiva (nativos) y el paradigma del experto (inmigrantes digitales), algunas de cuyas premisas básicas se explican solamente por la aparición de las tecnologías digitales. Tras esta contextualización teórica, exponem…
Teoría y concepto del arte moderno. Reflexiones sobre la historia del arte
2005
El presente artículo es una reflexión de orden teórico y metodológico sobre el concepto de Arte Moderno (s. XV-XVIII) aplicado a la universidad española. Un repaso a las ideas que el autor considera fundamentales en el desarrollo de la teoría, docencia e investigación del mencionado período artístico e histórico. This article is a theoretical and methodological reflection about the Modern Art concept (15th-18th centuries) applied to the Spanish University. A review of the ideas that the author considers to be basic in the development of theory, teaching, and research about the abovementioned artistic and historical period.

Inverse Malthusianism and Recycling Economics: The Case of the Textile Industry
2020
The current use of natural resources in the textile industry leads us to introduce a new economic concept called inverse Malthusianism describing a context in which population grows linearly and resource consumption grows exponentially. Inverse Malthusianism implies an exponential increase in environmental impact that recycling may contribute to reduce. Our main goal is to extend the analysis of materials selection under the principle of equimarginality proposed by Jevons. As a first result, we show the particular circumstances under which policies excluding recycled supplies are never optimal. We also aim to overcome the difficulties of reducing environmental aspects to monetary units. To …
Cost-driven framework for progressive compression of textured meshes
2019
International audience; Recent advances in digitization of geometry and radiometry generate in routine massive amounts of surface meshes with texture or color attributes. This large amount of data can be compressed using a progressive approach which provides at decoding low complexity levels of details (LoDs) that are continuously refined until retrieving the original model. The goal of such a progressive mesh compression algorithm is to improve the overall quality of the transmission for the user, by optimizing the rate-distortion trade-off. In this paper, we introduce a novel meaningful measure for the cost of a progressive transmission of a textured mesh by observing that the rate-distor…
Protective effect of paraoxonase-2 against endoplasmic reticulum stress-induced apoptosis is lost upon disturbance of calcium homoeostasis
2008
PON2 (paraoxonase-2) is a ubiquitously expressed antioxidative protein which is largely found in the ER (endoplasmic reticulum). Addressing the cytoprotective functions of PON2, we observed that PON2 overexpression provided significant resistance to ER-stress-induced caspase 3 activation when the ER stress was induced by interference with protein modification (by tunicamycin or dithiothreitol), but not when ER stress was induced by disturbance of Ca2+ homoeostasis (by thapsigargin or A23187). When analysing the underlying molecular events, we found an activation of the PON2 promoter in response to all tested ER-stress-inducing stimuli. However, only tunicamycin and dithiothreitol resulted i…
E-portfolio e flipped classroom: un’indagine esplorativa con i futuri insegnanti di scuola primaria
2023
Il contributo intende far riflettere sul tema della formazione dei futuri insegnanti di scuola primaria, a partire dall’impiego dell’e-portfolio come dispositivo innovativo per promuovere l’acquisizione della competenza riflessiva e autovalutativa all’interno della flipped classroom. La ricerca, che ha coinvolto 154 studenti del Corso di laurea magistrale in Scienze della Formazione Primaria dell’Università degli Studi di Palermo, che frequentavano il corso di Docimologia nell’anno accademico 2020/2021, presenta i presupposti teorici, gli obiettivi e le modalità operative di un percorso che ha visto l’impiego dell’e-portfolio nella flipped per promuovere lo sviluppo delle competenze docimol…
Raman-Mössbauer-XRD studies of selected samples from “Los Azulejos” outcrop: A possible analogue for assessing the alteration processes on Mars
2016
The outcrop of “Los Azulejos” is visible at the interior of the Cañadas Caldera in Tenerife Island (Spain). It exhibits a great variety of alteration processes that could be considered as terrestrial analogue for several geological processes on Mars. This outcrop is particularly interesting due to the content of clays, zeolite, iron oxides, and sulfates corresponding to a hydrothermal alteration catalogued as “Azulejos” type alteration. A detailed analysis by portable and laboratory Raman systems as well as other different techniques such as X ray diffraction (XRD) and Mössbauer spectroscopy has been carried out (using twin-instruments from Martian lander missions: Mössbauer spectrometer MI…
