Este trabajo examina los diferentes reparos que el recurso a las ideas procedentes de la cultura pública como base de su concepción de la justicia le ha procurado a Rawls. Ese examen se propone establecer dos conclusiones. Primera, frente a quienes sugieren que, con la apelación a tales fundamentos, la solidez del método de justificación que Rawls articula se resiente gravemente y los que esgrimen que, con esa apelación, Rawls renuncia a las pretensiones de universalidad que son consustanciales a la (...) doctrina liberal, intenta poner de manifiesto que el papel que esas ideas cumplen en la justificación de una concepción política de la justicia como la suya únicamente muestra la congruencia que la obra de Rawls exhibe en la manera de entender la naturaleza de la justificación y la clase de elementos sobre los cuales se articula. Segunda, frente a quienes sostienen que el método de justificación empleado por Rawls entraña alguna forma de relativismo o etnocentrismo, trata de evidenciar que ese método no conduce a ese tipo de posiciones, por más que tome como base nuestros juicios considerados y nociones políticas fundamentales.

Background: Pain has been associated with structural changes of the brain. However, evidence regarding white matter changes in response to acute pain protocols is still scarce. In the present study, we assess the existence of differences in brain white matter related to pain intensity reported by patients undergoing surgical removal of a mandibular impacted third molar using diffusion tensor imaging analysis.Methods: 30 participants reported their subjective pain using a visual analog scale at three postsurgical stages: under anesthesia, in pain, and (...) after the administration of an analgesic. The diffusion data were acquired prior to surgery.Results: DTI analysis yielded significant positive associations of fractional anisotropy in white matter areas related to pain processing with the differences in pain between the three postsurgery stages. Extent and location of these associations depended on the magnitude of the subjective pain differences. Tractography analysis indicated that some pain–tract associations are significant only when pain stage is involved in the contrast, while others are only when anesthesia is involved in the contrast.Conclusions: The association of white matter fractional anisotropy and connectivity, measured before the pain stages, with subjective pain depends on the magnitude of the differences in pain scores.

Background: Treating medication-refractory freezing of gait in Parkinson’s disease remains challenging despite several trials reporting improvements in motor symptoms using subthalamic nucleus or globus pallidus internus deep brain stimulation. Pedunculopontine nucleus region DBS has been used for medication-refractory FoG, with mixed findings. FoG, as a paroxysmal phenomenon, provides an ideal framework for the possibility of closed-loop DBS.Methods: In this clinical trial, five subjects with medication-refractory FoG underwent bilateral GPi DBS implantation to address levodopa-responsive PD symptoms with open-loop stimulation. Additionally, PPN (...) DBS leads were implanted for CL-DBS to treat FoG. The primary outcome of the study was a 40% improvement in medication-refractory FoG in 60% of subjects at 6 months when “on” PPN CL-DBS. Secondary outcomes included device feasibility to gauge the recruitment potential of this four-lead DBS approach for a potentially larger clinical trial. Safety was judged based on adverse events and explantation rate.Findings: The feasibility of this approach was demonstrated as we recruited five subjects with both “on” and “off” medication freezing. The safety for this population of patients receiving four DBS leads was suboptimal and associated with a high explantation rate of 40%. The primary clinical outcome in three of the five subjects was achieved at 6 months. However, the group analysis of the primary clinical outcome did not reveal any benefit.Interpretation: This study of a human PPN CL-DBS trial in medication-refractory FoG showed feasibility in recruitment, suboptimal safety, and a heterogeneous clinical effect in FoG outcomes.

Altruism and solidarity are concepts that are closely related to organ donation for transplantation. On the one hand, they are typically used for encouraging people to donate. On the other hand, they also underpin the regulations in force in each country to different extents. They are often used indistinctly and equivocally, despite the different ethical implications of each concept. This paper aims to clarify to what extent we can speak of altruism and solidarity in the predominant models of organ donation. (...) It also raises the ethical question of whether these categories are adequate as a basis for such models, bearing in mind that organs are a scarce resource and that a shortage of them may mean that fewer lives are saved or improved.

The purpose of this paper is to analyse the Spanish mobile phone industry to determine how mobile phone companies and certain institutions can improve protection for children who use mobile phones. We carried out a multivariate statistical analysis using anonymous primary data from mobile phone companies, and institutions and associations that protect children, to compare these stakeholders’ opinions and to put forward solutions. We proved that, even though some European countries have made an effort to provide safer ICT services, all (...) stakeholders still need to cooperate and agree on solutions to the commercial problems associated with children using mobile phones. This can be done by signing codes of conduct. We found that even though some companies implement measures to protect children from accessing harmful content via their mobile phones, they do so for reasons of legal and not social responsibility.

Resumen La ética es un saber filosófico que puede ser enfocado de distintas maneras, y una de ellas es el enfoque de la vulnerabilidad, que es un aspecto evidente de la realidad humana. Desde este punto de vista, es preciso distinguir entre la vulnerabilidad general y la vulnerabilidad contextual. Por su parte, en el caso de la vulnerabilidad contextual, es necesario distinguir entre la que es producto de opciones voluntarias y la que se produce por razones involuntarias. En el marco (...) de estas distinciones, reflexionamos sobre la situación de pandemia mun dial que estamos padeciendo y proponemos algunas medidas de carácter ético que pueden ser útiles para afrontar la crisis.Ethics is a philosophical knowledge that can be approached in different ways, and one of them is the approach to vulnerability, which is an evident aspect of human reality. From this point of view, it is necessary to distinguish between general vulnerability and contextual vulnerability. In the case of contextual vulnerability, it is necessary to distinguish between that which is the product of voluntary choices and that which occurs for involuntary reasons. Within the framework of these distinctions, we reflect on the global pandemic situation that we are suffering from and propose some ethical measures that may be useful in facing the crisis. (shrink)

Partiendo de las traducciones de las crónicas Iftitah al-Andalus de Ibn al-Qutiyya y Ajbar maymu,a recientemente publicadas por David James, se discuten en profundidad los aspectos historiográficos de ambos textos y la bibliografía sobre el tema.

Los Massalik al-absar de Ibn fadl Alláh al-Umari incluyen un breve resumen de la Historía de los omeyas en al-Andalus. En este trabajo se analizan las relaciones textuales entre ese pasaje y el Muqtabis de Ibn Hayyán, crónica que resulta ser la fuente casi única utilizada por al- Umari para redactar ese capitulo.

La Ilustración es un gran torrente que marcó un hito en la Historia del mundo, por sus implicaciones po-líticas, sociales, culturales y económicas. Este fenómeno es conocido popularmente desde Kant como la en-trada en la mayoría de edad de la sociedad: abandonar viejos fanatismos y tener valor de servirse del propio entendimiento. El objetivo de este artículo es mostrar las interpretaciones dominantes de este fenómeno his-tórico que han marcado su recepción en la academia y mostrar la singular aproximación del filósofo (...) francés Michel Foucault.

Análisis historiográfico del relato de las vicisitudes del alfaquí T.a-lu-t, elaborado por Ibn al-Qu-t.iyya y reproducido por numerosas fuentes andalusíes y orientales. De dicho análisis se desprende que la supuesta versión amplia de la crónica de Ibn al-Qu-t.iyya nunca existió y que la coincidencia entre varias obras en presentar una versión extensa del relato es debida a su común dependencia de un subarquetipo que amplificó retóricamente el texto original de Ibn al- Qu-t.iyya.

The organ donation and transplantation (ODT) system heavily relies on the willingness of individuals to donate their organs. While it is widely believed that public trust plays a crucial role in shaping donation rates, the empirical support for this assumption remains limited. In order to bridge this knowledge gap, this article takes a foundational approach by elucidating the concept of trust within the context of ODT. By examining the stakeholders involved, identifying influential factors, and mapping the intricate trust relationships among (...) trustors, trustees, and objects of trust, we aim to provide a comprehensive understanding of trust dynamics in ODT. We employ maps and graphs to illustrate the functioning of these trust relationships, enabling a visual representation of the complex interactions within the ODT system. Through this conceptual groundwork, we pave the way for future empirical research to investigate the link between trust and organ donation rates, informed by a clarified understanding of trust in ODT. This study can also provide valuable insights to inform interventions and policies aimed at enhancing organ donation rates. (shrink)

Los estados eran tradicionalmente los encargados de responder del ámbito público y de promover los derechos humanos (Ruggie, 2013); los mercados atendían a la generación de valor económico; y el tercer sector se encargaba de la integración social. Sin embargo, hoy en día esto ha cambiado, ya no es equivalente la responsabilidad pública con la responsabilidad estatal. Aunque los estados siguen siendo los máximos responsables, no son los únicos agentes responsables de esa tarea. Ahora hablamos de una sociedad civil globalizada (...) (García-Marzá, 2013).

We present the resistive switching characteristics of Metal-Insulator-Metal devices based on amorphous Al2O3which is deposited by Atomic Layer Deposition. A maximum processing temperature for this memory device is 300°C, making it ideal for Back-End-of-Line processing. Although some variations in the forming, set, and reset voltages are obtained for many of the measured MIM devices, thememristoreffect has been obtained after cyclicI-Vmeasurements. These resistive transitions in the metal oxide occur for bothbipolarandunipolarconditions, while theIOFF/IONratio is around 4–6 orders of magnitude and is formed (...) at gate voltages ofVg<4 V. In unipolar mode, a gradual reduction inVSETis observed and is related to combined incomplete dissolution of conductive filaments which leaves some residuals and thickening of chemically reduced Al2O3during localized Joule heating. This is important because, by analyzing the macroscopic resistive switching behavior of this MIM structure, we could indirectly relate it to microscopic and/or nanoscopic phenomena responsible for the physical mechanism upon which most of these devices operate.

Objective: To measure the stability of life-sustaining treatment preferences amongst older people and analyse the factors that influence stability. Design: Longitudinal cohort study. Setting: Primary care centres, Granada (Spain). Eighty-five persons age 65 years or older. Participants filled out a questionnaire with six contexts of illness (LSPQ-e). They had to decide whether or not to receive treatment. Participants completed the questionnaire at baseline and 18 months later. Results: 86 percent of the patients did not change preferences. Sex, age, marital status, (...) hospitalisation, and self-perception of health and pain did not affect preferences. Morbidity and the death of a relative did. Conclusion: Stability of preferences of older persons in relation to end-of-life decisions seems to be more probable than instability. Some factors, such as the death of a relative or the increase in morbidity, can change preferences. These findings have implications for advance directives (ADs) and advance care planning. (shrink)

Background: This research explores how public awareness and attitudes toward donation and transplantation policies may contribute to Spain's success in cadaveric organ donation. Materials and Methods: A representative sample of 813 people residing in Andalusia (Southern Spain) were surveyed by telephone or via Internet between October and December 2018. Results: Most participants trust Spain's donation and transplantation system (93%) and wish to donate their organs after death (76%). Among donors, a majority have expressed their consent (59%), and few nondonors have (...) expressed their refusal (14%). Only a minority are aware of the presumed consent system in force (28%) and feel sufficiently informed regarding the requirements needed to be an organ donor (16%). Participants mainly consider that relatives should represent the deceased's preferences and be consulted when the deceased's wishes are unknown, as is the case in Spain. Conclusion: Public trust in the transplant system may contribute to Spain's high performance in organ donation. High levels of societal support toward organ donation and transplantation do not correspond with similar levels of public awareness of donation and transplantation policies in Spain. (shrink)
