X-ray bursts and burst oscillations from the slowly spinning X-ray pulsar IGR J17480-2446 (Terzan 5)
2011
The newly discovered 11-Hz accreting pulsar, IGR J17480-2446, located in the globular cluster Terzan 5, has shown several bursts with a recurrence time as short as a few minutes. The source shows the shortest recurrence time ever observed from a neutron star. Here we present a study of the morphological, spectral and temporal properties of 107 bursts observed by the Rossi X-ray Timing Explorer. The recurrence time and the fluence of the bursts clearly anticorrelate with the increase in the persistent X-ray flux. The ratio between the energy generated by the accretion of mass and that liberated during bursts indicates that helium is ignited in a hydrogen-rich layer. Therefore, we conclude th…
Financial Incentives for Living Organ Transfer?
2020
In 2012, almost 4,500 people died in the United States while waiting for kidney transplants. In 2013, 4,100 died in the European Union while officially placed on waiting lists. To solve this problem, there are essentially two ethi-cally acceptable solutions; but both have, in their current state, disadvantages. The first solution would be having financial incentives for living organ transfer. The second one would be adopting a model, like the Spanish or Cro-atian ones, which we can denominate as the «imperfect altruistic» model. En 2012, casi 4500 personas murieron en Estados Unidos mientras esperaban trasplantes de riñón. En el transcurso de 2013, 4100 pacientes murieron en la Unión Europe…
Hart’s blind spot. The missing piece in The Concept of Law
2014
Al inicio de El Concepto de Derecho, Hart sugiere una asimilación errónea entre conducta que es «no opcional» y conducta que es «obligatoria» (i. e. conducta que o es forzada o sometida a una obligación). Esta asimilación vicia el argumento del libro en su conjunto, llevándole a Hart a descuidar las diferentes vías en las que el derecho monitorea, corrobora o constituye relaciones de poder. Es cierto y evidente que en The Concept of Law la atención se dedica a los poderes normativos, legales. Sin embargo, el poder social bruto, y las relaciones del derecho con él —el papel del derecho como una pieza en la maquinaria de los poderes sociales— están ampliamente ignorados. Éste es, de alguna ma…
Principles, balancing, and the separation between law and morals: on neo-constitutionalism and its critics
2011
En el ensayo Constitucionalismo principialista y constitucionalismo garantista, Luigi Ferrajoli ofrece una oportuna clarificación teórica y conceptual sobre el así llamado neoconstitucionalismo. Por mi parte, en esta contribución intentaré desarrollar algunas observaciones sobre tres puntos acerca de los cuales me encuentro en relativo desacuerdo con el análisis de Ferrajoli: el tratamiento de la distinción entre reglas y principios, la interpretación de la práctica de la ponderación, y el problema de la separación entre Derecho y moral. Además, ofreceré un panorama de los significados del (neo)constitucionalismo, y, respecto a tal panorama, consideraré el modo en el cual Ferrajoli sitúa su…
Conflicts between Fundamental Rights: a Criticism to Luigi Ferrajoli
2009
El objeto de este breve texto es poner de relieve alguna duda acerca de un específico, aunque no marginal, aspecto de la compleja teoría de los derechos fundamentales construida por Ferrajoli: el problema del conflicto entre derechos fundamentales. En primer lugar, ofreceré un sumario bastante genérico sobre la presencia (por lo menos aparente, o potencial) de conflictos entre derechos fundamentales en el panorama constitucional contemporáneo. De ahí pasaré a ilustrar la estrategia elaborada por L. Ferrajoli para argumentar la tesis de la ausencia o, al menos, la extremadamente reducida y marginal presencia de los conflictos entre derechos fundamentales. Por último, mostraré algunas posible…
Some arguments supporting an interpretative approach to legal knowledge
2014
La scienza giuridica di matrice giuspositivista istituisce un legame stringente tra diritto e linguaggio. Secondo questa prospettiva, il diritto è il discorso del legislatore e la scienza giuridica non è altro che un discorso sopra un discorso: un meta-linguaggio descrittivo del linguaggio prescrittivo del legislatore. Questa concezione del diritto e questo modello di scienza giuridica sono in crisi da alcuni decenni. Nel mio saggio presento quattro argomenti volti a evidenziare i limiti di questo approccio al diritto: l’argomento epistemologico, l’argomento del pluralismo epistemologico, l’argomento della svolta interpretativa e, infine, l’argomento funzionalista. Questi argomenti non stan…
Manuel Vázquez Montalbán y sus heterónimos en la revistra "Triunfo"
2022
The volume collects and analyzes the collaborations of Manuel Vázquez Montalbán in the magazine Triunfo, from the opinion article, to the report, from the short story to the comic strip, focusing on the use of heteronomous words. Following the path of the genre, the style and the narrative perspectives of the different contributions, the fertile osmosis between literary discourse and journalistic discourse is thus verified. The weekly appeared in 1946 in Valencia, playing a role of theater and film information and criticism. Since its transfer to Madrid in 1948, the magazine expanded its interests, inserting articles on domestic and foreign policy, until, in the 1960s, it became the intelle…

Cognitive rehabilitation of schizophrenia through NeuroVr training.
2013
Cognitive difficulties are prevalent in people with diagnosis of schizophrenia and are associated with poor long-term functioning. In particular, memory, selective, divided and sustained attention and executive functions are altered by this disease. We used a Virtual Reality environment (developed via the NeuroVr2.0 software) for the rehabilitation of shifting, sustained attention and action planning functions using tasks reminiscent of daily life tasks. Test and retest showed significant differences in the assessed cognitive dimensions.
Virtual reality environments to rehabilitation attention deficits in schizophrenic patients
2016
Abstract. Cognitive dysfunction is a core feature of schizophrenia. Patients with schizophrenia shown perform poorly on tasks that require vigilance or sustained attention. Patients with more pronounced attention deficits are least likely to acquire skills in psychosocial programs as the attention problems makes it difficult for them to process the information given in groups, and they may not be able to sustain attention for the session duration. The study aimed to develop a Virtual Reality cognitive training to improve the selective, divide and sustained attention. Specifically, we developed, via the NeuroVr 2.0 software, three different virtual environments with the hierarchical sequence…
