El antiguo problema de la libertad y el determinismo ha sido retomado en nuestros días por las neurociencias desde una perspectiva naturalista. Son muchos los problemas metodológicos y conceptuales a los que se enfrentan los investigadores al tratar de resolver científicamente la pregunta por la existencia del libre albedrío. Nuestro objetivo será someter a crítica uno de los presupuestos de estas investigaciones, la posibilidad de cuantificar la libertad como un hecho. Para ello expondremos en primer lugar las dificultades relativas a (...) esta pretensión. Tras ello estableceremos cuáles son las condiciones de posibilidad de la libertad en aras de someter a crítica las perspectivas psicológica y neurocientífica, sugerimos que ambas son incapaces de ofrecer conocimiento sobre la existencia de tales condiciones. Asimismo, ofreceremos algunas consideraciones metodológicas tomando como eje de la crítica el famoso experimento de Libet. (shrink)

El capitalismo histórico ha experimentado, en la escala mundial que hoy le corresponde, profundos cambios que han modificado sustancialmente su componente de acumulación, pero también, de forma significativa, el de regulación, perturbando críticamente su forma de gestionar las inequidades, desigualdades y doxas que él mismo produce. Actualmente, la expansión de un capitalismo autoritario premunido del paradigma mercantil, promueve una cultura individual que ha calado duramente en los sujetos ..

El punto central del artículo lo constituyen las diferencias entre el análisis marxista clásico o “sistémico” y sus nuevas vertientes “abiertas” o “autonomistas”. Se crítican ciertos discursos testimoniales y rebeldes de la resistencia anticapitalista (John Holloway), las que no darían cuenta del legado teórico de las modalidades clásicas del antagonismo Capital/Trabajo, surgidas de la experiencia sociohistórica de las luchas sociales. Por el contrario, el texto aboga por un análisis más profundo de la nueva fase del capitalismo mundializado y por el (...) rescate de formas organizativas de resistencia que den cuenta del nuevo contexto global.

In this article, we first review the development of clinical ethics in pediatrics in the United States. We report that, over the last 40 years, most children’s hospitals have ethics committees but that those committees are rarely consulted. We speculate that the reasons for the paucity of ethics consults might be because ethical dilemmas are aired in other venues. The role of the ethics consultant, then, might be to shape the institutional climate and create safe spaces for the discussion of (...) difficult and sometimes contentious issues. Finally, we report how pediatric clinical ethics has evolved differently in a number of other countries around the world. (shrink)

Traditionally, philosophical inquiry into pedagogical issues has occurred far from the classrooms in which pedagogy materialises. However, an organised form of inquiry into issues of a normative nature and of an analytic nature, making use of ideas obtained in an empirical way in classroom and classroom-related situations, is both feasible and desirable. About desirability, this form of inquiry depends on the particularities of the local situations, and that helps to take them into account when deciding on how to improve pedagogical (...) practice. That is, it contextualises pedagogical decisions. About feasibility for normative issues, an analysis based on Donald Davidson’s philosophy of language shows that there is nothing that compels empirical observations to be descriptive and to not be normative. And normative occasional beliefs acquired empirically can serve as a general confrontation or testing field for ideas about the justification of pedagogical actions or strategies. About feasibility for analytic issues, as a consequence of giving up the analytic–synthetic distinction it is argued that they can also be explored by means of occasional beliefs acquired empirically, when confronted with the implications of the definition of any pedagogical concept.

The sentential logic S extends classical logic by an implication-like connective. The logic was first presented by Chellas as the smallest system modelled by contraining the Stalnaker-Lewis semantics for counterfactual conditionals such that the conditional is effectively evaluated as in the ternary relations semantics for relevant logics. The resulting logic occupies a key position among modal and substructural logics. We prove completeness results and study conditions for proceeding from one family of logics to another.

The current dominant approach on the assessment of critical thinking takes as a starting point a conception of criticality that does not commit to any substantive view or context of meaning concerning what issues are relevant to be critical about in society or in life. Nevertheless, as a detailed examination of the identification of assumptions shows, when going from the theory of critical thinking to the praxis of producing and evaluating arguments, the critical person will inevitably make such commitments from (...) particular perspectives, using particular contexts of meaning. But then she may fail to take notice of relevant ones and may end up using her critical powers in a mercenary way. It is then proposed, in the context of assessment of critical thinking, to choose and use some privileged contexts of meaning, while making them available for critical scrutiny and allowing for the possibility that new ones be brought up by those being assessed.

Some authors have argued that consideration of alternative claims, theories, or worldviews is necessary for a proper or sound critical assessment of a claim or set of claims. However, an understanding of interpretation and beliefs as inherently holistic suggests that interpretation already involves the recogllition of alternatives, and that therefore assessment also necessarily involves their comparison. Starting from this idea, it will be argued that presuppositions can be regarded as limits to the range of alternatives that are considered by the (...) author of the claims, as seen by an interpreter making the assessment. However, a result of this consists in the fact that these assumptions can only be found in the conversational interaction between the author’s and the interpreter’s broader belief systems. Some implications for a conversational form of criticality will also be derived from here. (shrink)

Objectives: To explore opinions and attitudes regarding the current information-giving practices in research involving adults with intellectual disabilities.Design: Qualitative focus group study with a purposive sample.Setting: An intellectual disabilities service within the NHSParticipants: A sample of 26 individuals including adults with mild intellectual disability, carers, clinicians, care managers and the charitable sector.Results: Three main themes were identified: process, format, and content. There was agreement that there is a need for improvement in the process and quality of information giving. With regard (...) to the content of information, there was little discrepancy between the study findings and existing guidance.Conclusions: Information should be presented in different formats and prepared with input from appropriate professions. Additionally the roles of peers, carers and other professionals in the process of information giving should be considered. (shrink)

International law is not merely a set of rules or processes, but is a professional activity practised by a diversity of figures, including scholars, judges, counsel, teachers, legal advisers and activists. Individuals may, in different contexts, play more than one of these roles, and the interactions between them are illuminating of the nature of international law itself. This collection of innovative, multidisciplinary and self-reflective essays reveals a bilateral process whereby, on the one hand, the professionalisation of international law informs discourses (...) about the law, and, on the other hand, discourses about the law inform the professionalisation of the discipline. Intended to promote a dialogue between practice and scholarship, this book is a must-read for all those engaged in the profession of international law. (shrink)

Given its non-invasive nature, there is increasing interest in the use of transcutaneous vagus nerve stimulation across basic, translational and clinical research. Contemporaneously, tVNS can be achieved by stimulating either the auricular branch or the cervical bundle of the vagus nerve, referred to as transcutaneous auricular vagus nerve stimulation and transcutaneous cervical VNS, respectively. In order to advance the field in a systematic manner, studies using these technologies need to adequately report sufficient methodological detail to enable comparison of results between (...) studies, replication of studies, as well as enhancing study participant safety. We systematically reviewed the existing tVNS literature to evaluate current reporting practices. Based on this review, and consensus among participating authors, we propose a set of minimal reporting items to guide future tVNS studies. The suggested items address specific technical aspects of the device and stimulation parameters. We also cover general recommendations including inclusion and exclusion criteria for participants, outcome parameters and the detailed reporting of side effects. Furthermore, we review strategies used to identify the optimal stimulation parameters for a given research setting and summarize ongoing developments in animal research with potential implications for the application of tVNS in humans. Finally, we discuss the potential of tVNS in future research as well as the associated challenges across several disciplines in research and clinical practice. (shrink)

In this paper we set out a semantics for relevant (counterfactual) conditionals. We combine the Routley-Meyer semantics for relevant logic with a semantics for conditionals based on selection functions. The resulting models characterize a family of conditional logics free from fallacies of relevance, in particular counternecessities and conditionals with necessary consequents receive a non-trivial treatment.

The aim of this study was to analyze the association between physical activity and eating habits during the COVID-19 pandemic among Brazilian adults. A sample of 1,929 participants answered an online survey, however 1,874 were included in the analysis. The impact of the COVID-19 pandemic on eating habits was assessed inquiring about participants' intake of fruits, vegetables, fried foods, and sweets during the pandemic. Physical activity was assessed by asking participants about their weekly frequency, intensity and number of minutes/hours engaging (...) in structured physical activities per week. Participants were then stratified into categories based on moderate-to-vigorous intensity and into active or inactive. Increased sweets consumption was the most commonly reported change to eating habits, followed by an increase in the consumption of vegetables, fruits, and fried foods. Physical activity practice was related to lower consumption of fried foods and sweets. A cluster analysis revealed subjects with higher the level of physical activity was more likely to follow a healthy diet. Thus, physical activity was positively associated with healthier eating habits. Health authorities must recommend regular physical as a strategy to improve overall health during the COVID-19 pandemic. Future studies should address the physical activity interventions to improve health status during a pandemic. (shrink)

The present study investigated whether lexical access is affected by a regular phonological variation in connected speech: voice assimilation in French. Two associative priming experiments were conducted to determine whether strongly assimilated, potentially ambiguous word forms activate the conceptual representation of the underlying word. Would the ambiguous word form [sud] (either assimilated soute 'hold' or soude 'soda') facilitate 'bagage' 'luggage', which is semantically related to soute but not to soude? In Experiment 1, words in either canonical or strongly assimilated form (...) were presented as primes. Both forms primed their related target to the same extent. Potential lexical ambiguity did not modulate priming effects. In Experiment 2, the primes such as assimilated soute pronounced [sud] used in Experiment 1 were replaced with primes such as soude canonically pronounced [sud]. No semantic priming effect was obtained with these primes. Therefore, the effect observed for assimilated forms in Experiment 1 cannot be due to overall phonological proximity between canonical and assimilated forms. We propose that listeners must recover the intended words behind the assimilated forms through the exploitation of the remaining traces of the underlying form, however subtle these traces may be.

We study the filter ℒ*(A) of computably enumerable supersets (modulo finite sets) of an r-maximal set A and show that, for some such set A, the property of being cofinite in ℒ*(A) is still Σ0 3-complete. This implies that for this A, there is no uniformly computably enumerable “tower” of sets exhausting exactly the coinfinite sets in ℒ*(A).

§ 1. Introduction. Perhaps the most surprising recent development in complexity theory is the discovery that the class NP can be characterized using a form of randomized proof checker that only examines a constant number of bits of the “proof” that a string is in a language [6, 5, 31, 3, 4]. More specifically, writing ∣x∣ for the length of a string x, a language L in the class NP of languages recognizable in Nondeterministic polynomial time is traditionally given by (...) a polynomial p and a polynomial-time predicate P such that a string x is in L iff there is some string y satisfying P, where ∣y∣ ≤ p. Intuitively, we can think of a string y as a possible proof that x ϵ L, with the predicate P some kind of proof checker that distinguishes good proofs from bad ones. A string x is therefore in a language L ϵ NP if there is a short proof that x ϵ L, and not in L otherwise. The surprising discovery is that the deterministic proof checker that reads the entire input and proof can be replaced by a probabilistic verifier that on input x and possible proof y, where y is presented in a certain way, flips at most O coins and reads at most a constant number of bits of x and y. Obviously, a probabilistic verifier that does not read the whole proof will sometimes make mistakes. However, the surprising and essentially non-intuitive mathematical fact is that for each language L in NP, it is possible to find a polynomial q and verifier V flipping a logarithmic number of coins and reading a constant number of bits such that, for any x ϵ L, there exists y with ∣y∣ ≤ q and with V accepting with probability 1 and, for x ∉ L, there is no y with ∣y∣ ≤ q and with V accepting with probability ≥ 1/4. This idea canalsobeextended to PSPACE [10, 9], using a game that alternates between two players instead of a proof presented by a “single player.”. (shrink)
