Este artigo tem por objetivo apresentar e discutir a sugestão de Fred Dretske para analisar o problema dos qualia. Tal problema, caro à Filosofia da Mente, ficou conhecido pela discussão desenvolvida por Thomas Nagel em seu clássico artigo What is it like to be a bat. Nesse artigo, Nagel postulou a impossibilidade de se conhecer, em perspectiva de terceira-pessoa, os aspectos da experiência humana. Ele considera que, mesmo após as descrições objetivas da experiência de um sujeito, escapariam ainda aspectos qualitativos, (...) fundamentais para se caracterizar os qualia. A partir de sua Tese Representacionista da mente, Dretske argumenta que seria possível dissolver esse problema se admitirmos que a mente é a face representacional do cérebro, a natureza dos qualia seria, assim, representacional. Nesse contexto, os fatos mentais relacionados às experiências seriam fatos representacionais: se conhecermos a natureza desses fatos representacionais conheceremos também a experiência do sistema que a representa. Diante de tal entendimento, discutimos em que medida a proposta dretskeana constitui uma alternativa ao problema dos qualia. (shrink)

Este ensaio pretende analisar a situação atual de confinamento imposta pela pandemia de Covid-19 a partir dos conceitos heideggerianos de técnica, quotidiano e preocupação. Defendemos que o isolamento oferece as condições materiais para que mais pessoas deem atenção a si mesmas e cuidem de se mesmas, do que resulta um deixar-ser tanto a própria liberdade quanto a do outro. Com isso, as possibilidades que somos são encaradas como tais, em especial nosso ser-para-a-morte.

In line with recent efforts to empirically study the folk concept of weakness of will, we examine two issues in this paper: (1) How is weakness of will attribution [WWA] influenced by an agent’s violations of best judgment and/or resolution, and by the moral valence of the agent’s action? (2) Do any of these influences depend on the cognitive dispositions of the judging individual? We implemented a factorial 2x2x2 between–subjects design with judgment violation, resolution violation, and action valence as independent (...) variables, and measured participants’ cognitive dispositions using Frederick’s Cognitive Reflection Test [CRT]. We conclude that intuitive and reflective individuals have two different concepts of weakness of will. The study supports this claim by showing that: a) the WWA of intuitive subjects is influenced by the action’s (and probably also the commitment’s) moral valence, while the WWA of reflective subjects is not; b) judgment violation plays a small role in the WWA of intuitive subjects, while reflective subjects treat resolution violation as the only relevant trait. Data were collected among students at two different universities. All subjects (N=710) answered the CRT. A three-way ANOVA was first conducted on the whole sample and then on the intuitive and reflective groups separately. This study suggests that differences in cognitive dispositions can significantly impact the folk understanding of philosophical concepts, and thus suggests that analysis of folk concepts should take cognitive dispositions into account.

ObjectiveTest anxiety (TA) is a construct that has scarcely been studied based on Lang’s three-dimensional model of anxiety. The objective of this article is to investigate the repercussion of sociodemographic and academic variables on different responses for each component of anxiety and for the type of test in adolescent students.MethodA total of 1181 students from 12 to 18 years old (M= 14.7 and SD = 1.8) participated, of whom 569 were boys (48.2%) and 612 girls (51.8%). A sociodemographic questionnaire and (...) theCuestionario de Ansiedad ante los examenes-Adaptado (CAEX-A)[Test Anxiety Questionnaire-Adapted] an adaptation for Spanish secondary school levels (ESO) and Bachillerato were administered.ResultsGirls scored higher on the cognitive and physiological components of TA than boys, the intensity of the physiological response increasing with age. Bachillerato level students reported more physiological anxiety than those of ESO level. Students with better marks in the previous year presented more anxiety in the cognitive component, while those who obtained the lower mark presented higher anxiety values in the behavioral component. Participants reported that the types of tests that cause them more anxiety were oral tests in front of the class, oral presentation in front of a panel, and mathematics tests.ConclusionAdolescents show a differential response of TA based on the physiological, cognitive and motor components, mediated by the variables of gender, age, grade, academic performance and type of exam. These results serve to design specific intervention programs to manage anxiety in situations of academic assessment. (shrink)

El escenario energético de escasez a nivel mundial se empieza a reflejar fuertemente en América Latina. Chile tiene una política energética diseñada en el período dictatorial, y administrada en la democracia, que hace muy vulnerable su economía, su medio ambiente y su seguridad. En este artículo se analizan críticamente los diversos aspectos que inciden fuertemente en el actual escenario energético chileno, sobre todo en lo que respecta a la política de integración con sus vecinos latinoamericanos, desde donde se puede vislumbrar (...) también una solución sustentable a los problemas energéticos futuros.

Neuroscience influences education, and these two areas have converged in a new field denominated “Neuroeducation.” However, the growing interest in the education–brain relationship does not match the proper use of research findings. In 2007, the Organization for Economic Cooperation and Development warned of the misunderstandings about the brain among teachers, labeling them as neuromyths. The main objective here is to observe the prevalence of the neuromyths in educators over time. After two decades of publications of research on neuromyths among in-service (...) or prospective teachers, this work presents a systematic scientific review. To select the articles, we used the words: “teachers,” “preservice teachers,” “neuromyths” combined with the Boolean data type “and.” The search was filtered according to the following criteria: identifiable author, written in English, Spanish, French, Italian, or Portuguese, word neuromyth in title, abstract, or keywords, research with a participant's survey, sample focused on educators, peer-review publication index in JCR, SJR, or ESCI. The documents were found through Web of Science, Scopus, PubMed, Dialnet, ProQuest, EBSCO-host, and Google Scholar. After the search, 24 articles were identified as being of sufficiently high quality for this systematic review. This result highlights that neuromyths are still the subject of attention almost two decades after their definition. The findings present neuromyths as the consequence of a lack of scientific knowledge, a communicative gap between scientists and teachers, and the low-quality information sources consulted by teachers. In addition, the data on protectors and predictors of neuromyths is inconsistent. There is also no standard scientific methodology nor a guideline to determine a new neuromyth. The results show the need to improve the scientific content in higher education and the importance of in-service teacher training. This research justifies the requirement for university professors to be active researchers and to establish a close link with educators from other fields and levels. Neuroeducation will be the bridge that unites scientific knowledge and practical application in education, with a rigorous, standard method for the entire scientific-educational community. (shrink)

RATIONALE AND AIMS: Total hip and knee replacements, usually, have long waiting lists. There are several prioritization tools for these kind of patients. A new tool should undergo a standardized validation process. The aim of the present study was to validate a new prioritization tool for primary hip and knee replacements. METHODS: We carried out a prospective study. Consecutive patients placed on the waiting list were eligible for the study. Patients included were mailed a questionnaire which included, among other questions, (...) the seven items of the priority tool and the Western Ontario and McMasters Universities Arthritis Index (WOMAC) specific questionnaire. The priority tool gives a score from 0 to 100 points, and three categories (urgent, preferent and ordinary). We studied the content and construct validity. We used Student's t-test or one-way analysis of variance. Correlational analysis was used to evaluate convergent and discriminate validity. RESULTS: The sample consisted of 838 patients (62.3% were female), with mean age of 70.2 years (SD 8.4). A total of 55.5% patients underwent knee replacement. Given that the tool was elaborated by patients and orthopaedic surgeons, it shows a good content validity. The priority score was statistically different (P < 0.001) among the three urgency categories created. The scores of the three WOMAC dimensions showed differences (P < 0.001) by the three urgency categories created. The correlations between the priority score and WOMAC dimensions were 0.79 (function), 0.69 (pain) and 0.51 (stiffness). The correlations between WOMAC items and items from priority tool were greater (0.47-0.69) between items measuring similar constructs than those measuring different constructs (0.27-0.49). These data are similar in both joints. CONCLUSIONS: Results support the validity of the prioritization tool to be used with patients waiting for hip or knee replacement. (shrink)

Abordamos aquí unos aspectos, posiblemente los menos conocidos, de la dilatada vida de Fray Diego de Deza, como son los orígenes de su linaje en la gallega Terra de Deza y el afincamiento durante la segunda mitad del siglo XIV de la que fue la rama familiar de Toro, su ciudad natal. No perteneciendo a la hidalguía de mayor abolengo y riqueza de los linajes allí establecidos, sus méritos personales le labraron un futuro prometedor, primero por la cátedra docente que (...) ocupó en Salamanca y sus altas dotes como maestro y, además, por la confianza que los Reyes Católicos depositaron en él al nombrarlo preceptor del malogrado príncipe heredero don Juan, lo que le hizo emprender una envidiable carrera tanto eclesiástica como por sus servicios a la Corona. Nuestro objetivo aquí no ha sido otro que vislumbrar sus relaciones parentales y sociales, obviando su brillante cursus honorum en ese doble rol de servicio al altar y al trono. (shrink)

La filosofía de los pensadores "presocráticos" ha sido abordada frecuentemente desde una perspectiva ontológica o cosmológica. El presente trabajo propone situar las consideraciones ontológicas o cosmológicas de estos pensadores en un marco más amplio, determinado por lo que el autor llama la "lógica de las retribuciones". Esta perspectiva más abarcadora tiene la ventaja de poder integrar en la exposición de las primeras filosofías de Grecia algunos textos frecuentemente desatendidos, por considerarlos puros elementos mitológicos o literarios. Desde este punto de vista (...) se abren nuevas vías para entender las relaciones entre filosofía y religión, al tiempo que se muestran las intenciones prácticas de la filosofía en sus mismos orígenes.

La indagación del segundo Heidegger acerca del ser encuentra su maduración en la doctrina del Ereignis, un nuevo concepto «post-metafísico», según Vattimo, con el que el filósofo alemán trata de responder a la pregunta de qué es el ser una vez ha mostrado, en su primera etapa intelectual, la esencial diferenciación ontológica. El ser no es un ente, ni aquello fijo e inmutable que fundamenta lo ente. Ni de él puede decirse que es; el ser «se da». Y se da (...) al hombre en un acto de donación recíproca en la totalidad del acontecer histórico. Vattimo parte de esta idea para concluir que el ser es evento que orbita en la constelación del Ge-Stell, el destino de la época actual en cuanto forma de desocultar el ser, de desvelar la verdad, y convierte a Heidegger en precursor de la postmodernidad y de su pensiero debole.

In this article we analyze in a new way the epistemological concept of mythical explanation. It is shown, within the framework of the theory of dynamic and complex systems, that this kind of explanation is grounded on the substitution of distributed causation by lineal and single causes. Considering four examples, we show which mechanism is operating in that substitution. The first one concerns a computational implementation of a racial segregation model. The second one will be the analysis of an imaginary (...) panic. The third one starts with the theory, developed by René Girard, concerning sacrifice rituals and the emergence of scapegoats. Finally, the fourth one is based on the introduction of the imitation mechanism as an explanation for the financial markets behavior. (shrink)

An extensive literature has been accumulating, in recent years, on face-processing in sheep and on the relevance of faces for social interaction in this species. In spite of this, spontaneous preferences for face or non-face stimuli in lambs have not been reported. In this study we tested the spontaneous preference of 8-day-old lambs (N = 9) for three pairs of stimuli. In each pair, one stimulus was a face-like display, whereas the other presented the same inner features displaced in unnatural (...) positions. One pair of stimuli was obtained from photographic images of ewes’ faces, the other two pairs were schematic face-like stimuli. Lambs could differentiate the two stimuli obtained by photos of conspecifics, looking longer at the non-face stimulus (p < 0.05). We interpret this as a novelty preference, proving that few day-old lambs have already encoded the structural properties that define a face and recognize violations of those general properties.

One of the main challenges in medicine is to guarantee an appropriate drug supply according to the real needs of patients. Closed-loop strategies have been widely used to develop automatic solutions based on feedback variables. However, when the variable of interest cannot be directly measured or there is a lack of knowledge behind the process, it turns into a difficult issue to solve. In this research, a novel algorithm to approach this problem is presented. The main objective of this study (...) is to provide a new general algorithm capable of determining the influence of a certain clinical variable in the decision making process for drug supply and then defining an automatic system able to guide the process considering this information. Thus, this new technique will provide a way to validate a given physiological signal as a feedback variable for drug titration. In addition, the result of the algorithm in terms of fuzzy rules and membership functions will define a fuzzy-based decision system for the drug delivery process. The method proposed is based on a Fuzzy Inference System whose structure is obtained through a decision tree algorithm. A four-step methodology is then developed: data collection, preprocessing, Fuzzy Inference System generation, and the validation of results. To test this methodology, the analgesia control scenario was analysed. Specifically, the viability of the Analgesia Nociception Index as a guiding variable for the analgesic process during surgical interventions was studied. Real data was obtained from fifteen patients undergoing cholecystectomy surgery. (shrink)

This text proposes a conception of Richard Rorty’s philosophy from the distinction between systematic philosophy and edifying philosophy, proposing this distinction as a key to reading his neo-pragmatism and his political-ethical proposal of the 90s, whose consequence main will be his conception of liberal democracy, ironic citizen and post-philosophical culture.

Some doctors and nurses played a key role in Nazism. They were responsible for the sterilization and murder of people with disabilities. Nazi doctors used concentration camp inmates as guinea pigs in medical experiments that had military or racial objectives. What we have learnt about the behaviour of doctors and nurses during the Nazi period enables us to reflect on several issues in present-day medicine. In some authors' opinions, the teaching of the medical aspects of the Holocaust could be a (...) new model for education relating to professionalism, Human Rights, Bioethics and the respect of diversity. Teaching Medicine and the Holocaust could be a way of informing doctors and nurses of violations of Ethics in the past. Moreover, a Study Trip to Holocaust and Medicine related sites has a strong pedagogical value. Visiting Holocaust related sites, T4 centres and the places where medical experiments were carried out, has a special meaning for medical students. Additionally, tolerance, anti-discrimination, and the value of human life can be both taught and learned through this curriculum. The following article recounts our experiences of organizing and supervising a study trip with a group of medical students to some Holocaust and medicine-related sites in Berlin and Hadamar. The study tour included lectures at universities in Düsseldorf and Berlin. (shrink)

The Air Quality Index (AQI) shows the state of air pollution in a unique and more understandable way. This work aims to forecast the AQI in Algeciras (Spain) 8 hours in advance. The AQI is calculated indirectly through the predicted concentrations of five pollutants (O3, NO2, CO, SO2 and PM10) to achieve this goal. Artificial neural networks (ANNs), sequence-to-sequence long short-term memory networks (LSTMs) and a newly proposed method combing a rolling window with the latter (LSTMNA) are employed as the (...) forecasting techniques. Besides, two input approaches are evaluated: using only the data from the own time series of the pollutant in the first case or adding exogenous variables in the second one. Several window sizes are employed (24, 28 and 72 hours) with ANNs and LSTMNAs. Additionally, several feature ranking methods are applied in the exogenous approach to select the most relevant lagged variables to feed the models. Results show how the proposed exogenous approach increases the performance of the prediction models. Besides, the newly proposed method LSTMNA provides the best performances in most of the cases evaluated. Hence, it constitutes an exciting alternative to standard LSTMs and ANNs to predict pollutants concentrations and, consequently, the AQI. (shrink)
