El presente ensayo intenta repensar las ciencias humanas a partir de la idea de espíritu que manejan los pueblos de la Amazonía. Para ello, se dará cuenta del pensamiento crítico brasileño contemporáneo, que asume la alteridad y la crisis ambiental como ejes centrales de sus reflexiones, para luego articularlo a una idea de ciencias humanas que asuman como objeto no lo humano, sino lo viviente.

Entrevista a Miguel Valderrama por Raúl Rodríguez Freire.

Las investigaciones que Carlos Alchourrón desarrolló en la Filosofía del Derecho se vincularon, desde inicios de la década de 1980, con problemáticas críticas de la Inteligencia Artificial. Su contribución a la construcción de una lógica de las normas se conectó rápidamente con la deducción automática y los Sistemas Expertos Jurídicos. Su preocupación por la cuestión de los conflictos de obligaciones que pueden plantearse en un sistema normativo cuando el juez se enfrenta a la necesidad de emitir un veredicto considerando ciertos (...) hechos, se vinculó, en sus trabajos, con la noción más general de "condicionales derrotables" y con la formalización del Razonamiento No Monótono. Pero su contribución de mayor impacto fue aquella derivada de la búsqueda de una solución al problema de los resultados múltiples que surgen de la derogación de una norma en un sistema jurídico, problema que puede ser visto, en un contexto epistémico, como el de la contracción de un conjunto de creencias. Su enfoque constructivo, que desarrolló con David Makinson, convergió con el axiomático elaborado por Peter Gärdenfors, dando lugar al surgimiento de la teoría de los Cambios Racionales de Creencias, más conocida como AGM, teoría que fue adoptada en IA como un modelo standard para la especificación de las actualizaciones de Bases de Conocimiento, operaciones que, habitualmente, involucran la introducción de una nueva creencia que puede ser inconsistente con las anteriores. ¿Por qué AGM adquirió rápidamente carta de ciudadanía en IA, al punto de que su influencia, medida según la cantidad de menciones bibliográficas del artículo fundacional de 1985, se ha duplicado en la última década? Mostraremos en este trabajo que la teoría apareció en un momento de crisis de la IA y que el alto nivel de abstracción del modelo de AGM era lo que muchos investigadores de la disciplina estaban buscando. El presente artículo, luego de describir la génesis de AGM, realiza un análisis histórico de las circunstancias en las cuales la teoría se introdujo en la IA y una evaluación cuantitativa y cualitativa de su impacto en dicha disciplina. The main lines of research that Carlos Alchourrón developed in the Philosophy of Law, were connected, from the beginnings of the 80' s, to some critical problems in the Artificial Intelligence. His contributions to the construction of a logic of norms were rapidly linked to automatic deduction and the Legal Expert Systems. His concerns for the conflict of obligations that could arise in a normative system when a judge has to issue a ruling taking some particular facts into account were associated in his work with the more general notion of "defeasible conditionals" and with the formalization of Non Monotonic Reasoning. But his most relevant contribution was the one derived from the search of a solution to the problem of multiple outcomes resulting from the derogation of a norm in a legal corpus, which may be considered -within an epistemic framework- analogous to the contraction of a set of beliefs. The constructive approach he worked out with David Makinson converged with Peter Gärdenfors' axiomatic, giving rise to the formulation of the theory of Rational Changes of Belief, which was adopted in AI as a model for the specification of the updates of Knowledge Bases as it usually involves a new belief that may be inconsistent with the old ones.

The interest of assigning homework is frequently discussed due to its alleged low impact on student achievement. One of the current lines of research is to emphasize the quality of student homework engagement rather than the amount of time spent on homework. The aim of this study was to determine (a) the extent to which students’ prior achievement affects their homework engagement (i.e., time spent, time management, and amount of teacher-assigned homework done), and (b) how students’ intrinsic motivation towards homework (...) may mediate or moderate the relationship between prior achievement and the homework engagement variables. A large sample of students from the first four years of Secondary Education (N = 1899) completed questionnaires. The results showed that intrinsic motivation partially mediates, but does not moderate, the effect of prior achievement on the three variables related to homework engagement (time spent, time management, and amount of teacher-assigned homework done). These results highlight the importance of considering both students’ current level of achievement and their motivation towards homework engagement when assigning homework. (shrink)

The search for a systems‐level picture of metabolism as a web of molecular interactions provides a paradigmatic example of how the methods used to characterize a system can bias the interpretation of its functional meaning. Metabolic maps have been analyzed using novel techniques from network theory, revealing some non‐trivial, functionally relevant properties. These include a small‐world structure and hierarchical modularity. However, as discussed here, some of these properties might actually result from an inappropriate way of defining network interactions. Starting from (...) the so‐called bipartite organization of metabolism, where the two meaningful subsets (reactions and metabolites) are considered, most current works use only one of the subsets by means of so‐called graph projections. Unfortunately, projected graphs often ignore relevant biological and chemical constraints, thus leading to statistical artifacts. Some of these drawbacks and alternative approaches need to be properly addressed. (shrink)

In daily academic life, students are exposed to a wide range of potentially stressful situations which could negatively affect their academic achievement and their health. Among the factors that could be weakened by academic stress, attention has been paid to expectations of self-efficacy, which are considered one of the most important determinants for student engagement, persistence, and academic success. From a proactive perspective, research on academic stress has emphasized the importance of coping strategies in preventing harmful consequences. In recent years, (...) there has been a growing interest in discovering the extent to which individuals are able to combine different coping strategies and the adaptive consequences this flexibility entails. However, studies using this person-centered approach are still scarce in the academic context. On that basis, this current study had two objectives: (a) to examine the existence of different profiles of university students based on how they combined different approach coping strategies (positive reappraisal, support seeking, and planning); and (b) to determine the existence of differences in general expectations of self-efficacy between those coping profiles. 1072 university students participated in the study. The coping profiles were determined by Latent Profile Analysis (LPA). The differences in the self-efficacy variable were determined using ANCOVA, with gender, university year, and degree type as covariates. Four approach coping profiles were identified: (a) low generalized use of approach coping strategies; (b) predominance of social approach coping approaches; (c) predominance of cognitive approach coping approaches; (d) high generalized use of approach coping strategies. The profile that showed that a greater combination of the three strategies was related to higher general self-efficacy expectations, and vice versa. These results suggest that encouraging flexibility in coping strategies would help to improve university students’ self-efficacy. (shrink)

El objetivo central de este artículo consiste en argumentar a favor de la tesis de que es imposible o, al menos, excesivamente difícil evaluar creencias basadas en la memoria, especialmente cuando se justifican en los denominados recuerdos episódicos, lo que implica que las creencias basadas en la memoria episódica no pueden ser justificadas suficientemente para alcanzar el estatus de conocimiento. Para lograr este objetivo expondré brevemente las diferencias y las relaciones que hay entre memoria, recuerdo, creencia y conocimiento (o saber). (...) Posteriormente presentaré diversas formas en que ha sido entendida la memoria, así como algunas de las pruebas que han servido para medir la memoria ya que en función de estas se puede mantener que hay recuerdos falsos. Aunque estas pruebas son valiosas para los propósitos para las que fueron diseñadas, hay casos que se les escapan y estos tienen implicaciones epistemológicamente importantes, entre ellas que la memoria episódica no es una fuente confiable para justificar algunas de nuestras creencias y que estas cuenten como conocimiento.

En este trabajo ofreceré argumentos para mantener que el entorno co-textual de una expresión configura su significado y también conforma su referente. Donde el referente es resultado de una actividad metalingüística cuya base se encuentra en las operaciones lingüísticas de condensación, síntesis y reificación, entre otras. Lo anterior implica que se puede mantener una teoría referencial sin la necesidad de asumir compromisos ontológicos tal como lo manifestaron Russell y especialmente W. V. Quine. Me valdré de la construcción nominal “la radiación (...) adaptativa” con el objetivo de responder a qué tipo de entidades se refiere esta expresión. Una respuesta parcial e incompleta a esta interrogante la encontramos en Quine por esta razón intentaré desarrollarla más recurriendo a la lingüística operacional y a la lingüística de texto. In this paper I will offer arguments to show that the co-textual environment of an expression configures its meaning and also conforms its referent. Where reference is a result of a metalinguistic activity which is based on linguistic operations of condensation, synthesis and reification, among others. The above implies that we can maintain a referential theory without the necessity to assume ontological commitments as they manifested especially Russell and WV Quine. I will use the nominal construction “la radiación adaptativa” in order to respond to what kind of entities is covered by this expression. A partial and incomplete answer to this question is found in Quine for this reason I will try to develop appealing to operational linguistics and textual linguistics. (shrink)

Historicismo y Marxismo. El Historicismo, Ludovico Geymonat y la disputa en torno al Marxismo como método o concepción de mundo.

This paper offers a re-reading of the works of Umberto Eco, be they academic, journalistic or literary, with a pseudologic tone: his desire to investigate the mechanisms of lying, and their relation with fiction, falsification, error, secrecy, and conspiracy. The study will review some of his main academic texts in the fields of semiotics, rhetoric, and aesthetics, and will make some references to his recent novels and essay compilations, as well as offer an explanation of how the evolution of his (...) thoughts takes a pessimistic turn. The face of the lie, which initially was aesthetic consolation and consumerist delusion, and then a game of intelligence, a creative stimulus and an interpretive challenge, changes when serves the purpose of extortion, manipulation, and war. In short, it could be argued that Eco became increasingly disappointed by deceptions, and lost faith in fakes and forgeries. (shrink)

Background: I suggest this individualized care is a fundamental principle closely linked to nursing ethics and has important benefits for the patients, however, nurses do not always take into consideration the principles of individualized care. Moreover, there is no validated instrument to assess patients’ views of individualized care in Spanish-speaking countries. Objectives: To assess the validity and reliability of the Spanish version of the Individualized Care Scale-patient. Design: A cross-sectional study design was conducted. A questionnaire survey, including the Individualized Care (...) Scale-patient, was used for data collection. Psychometric properties of reliability and validity were assessed. Fit indices of the overall model were computed. Participants and research context: Survey data were collected from a sample of 118 inpatients at a public hospital in Spain. Ethical considerations: Informed consent from participants and ethical approval was obtained from a regional Clinical Research Ethics Committee. Findings: Ordinal Cronbach’s alphas were 0.966 for Individualized Care Scale-patient subscale A and 0.969 for Individualized Care Scale-patient subscale B. The polychoric correlation between each item and the subscale ranged between 0.653–0.874 and 0.604–0.916, respectively. The exploratory factor analysis revealed a three-factor solution. Personal life situation explained relatively large amounts of the variance. Goodness of fit index showed a good fit for the model. Discussion: This study confirms three factors underlining the individualized care concept, but some differences were found in the load of the factors, such as the relevance of “personal life situation” subscale, that need further research. Conclusion: The Spanish version of the Individualized Care Scale-patient is reliable, valid, user-friendly, and suitable to be used in Spanish-speaking countries showing satisfactory properties. This instrument may help managers better understand and develop areas in which patients perceive lower individualized care received and the factors influencing it. Such key information will help ensure the right of the patient to be respected as an individual. (shrink)

Judo is a multifactorial sport where many variables or key performance indicators such as force-velocity profile, bioenergetic capacity, technical and tactical skills, and cognitive and emotional competence play a role and influence the final result. While there have been many academic studies of these variables, usually in isolation, none have examined KPIs holistically or analyzed their impact on strategic performance. The main objective of the present study, therefore, is to apply a novel and easily replicable methodology to identify and prioritize (...) the main KPIs affecting performance in professional judo. Such a methodology was applied to the High-Performance Judo Centre of Valencia, using a multi-criteria decision aid technique: the analytic network process. The ANP is used to identify and quantify cause and effect relationships not only between KPIs but also between KPIs and performance objectives. Further, the ANP offers effective results when there is a lack of historical KPI data, because it is based on experts' opinions and judgments. A judo expert group comprising elite judo coaches and half-lightweight male judokas applied the methodology to discriminate between the characteristics required when aiming to reach high-level strategic objectives. The JEG, which consisted of five elite judokas, national and international champions, and three Olympic coaches—including a former European champion and silver medalist in a world championship—provided high added value to the study. The main findings were that the KPIs that made the most difference were mostly psychological, specifically motivation, stress, and team cohesion. Of these, motivation was by far the most important KPI for success in our case study, so judokas should make sure that they analyze it properly. Motivation is usually intrinsic to the competitor and should be maintained at a high level, not only during tournaments but also during daily training and lifestyle activities. Physical and other specific forms of training, as well as lifestyle KPIs, are very important for the elite competitor but are not sufficient to reach high-level objectives. The most important of these KPIs were Kumi-Kata, dual career, focus and concentration level, scouting, nutrition, and basic technique. Power and strength were the most important physical KPIs. In general, these are essential for meeting strategic objectives, but they do not make the crucial difference. This suggests that professional psychological support should be provided in daily training and that international team composition and internships should be fostered. (shrink)

Con una indagación cualitativa se intenta averiguar si el método de palabras generatrices de Paulo Freire presenta ventajas para la enseñanza-aprendizaje de la lengua escrita castellana en la edad infantil. Se extraen los datos de la experiencia práctica acumulada por profesorado que lo ha aplicado en el segundo ciclo. Cinco maestras aportan informes escritos individuales y dos equipos docentes se constituyen en grupos de discusión. Tras la categorización y análisis de los datos, se concluye que el método tiene muchas (...) ventajas. Entre las ventajas de tipo didáctico cabe resaltar el respeto al protagonismo del alumnado y a su pensamiento sincrético, ser muy motivador, conseguir la comprensión lectora desde el principio, desarrollar simultáneamente las conciencias léxica, silábica y fonológica; enriquecer el vocabulario, fijar una ortografía correcta, integrar todos los ámbitos de conocimiento, y desarrollar la capacidad simbólica y la creatividad. Como ventajas de tipo pedagógico: considerar los efectos de tipo actitudinal que actúan sobre los procesos cognoscitivos, adaptarse a los contextos, permitir al profesorado conocer mejor a su alumnado, propiciar el desarrollo de la dimensión afectivo-emocional, favorecer la socialización por trabajarse siempre en grupo y la ayuda entre iguales, el buen clima de aprendizaje y la colaboración familiar.

No presente ensaio, discute-se o impacto do negacionismo na Educação escolar. Essa ideologia é baseada em falsos argumentos, cujos protagonistas negam evidências cientificamente comprovadas, como forma de fortalecer seus anseios pelo poder. A narrativa negacionista atinge pessoas que aceitam acriticamente e replicam esses argumentos como se fossem verdades absolutas. Um dos resultados da disseminação e aceitação dessa ideologia é o estímulo a ações extremistas, como vimos acontecer recentemente no Brasil. A negação fomenta intencionalmente os analfabetismos histórico, social e científico. As (...) pessoas "contaminadas" por essa ideologia extremista ignoram os argumentos lógicos e permanecem alheias ao avanço da Ciência. Acreditam em disparates, como o chamado “terraplanismo”; são disseminadores de informações falsas; promovem “cruzadas” antivacinação; defendem o uso de medicamentos ineficazes; e fomentam o descrédito da democracia. As ideias de Paulo Freire, que estimulam o cultivo do pensamento crítico e emancipatório, é o aporte teóricometodológico que norteia este ensaio, contextualizado na prática docente dos autores, que consideram a Educação como uma prática de liberdade.

The consideration of racial differences in the biology of disease and treatment options is a hallmark of modern medicine. However, this time-honored medical tradition has no scientific basis, and the premise itself, that is, the existence of biological differences between the commonly known races, is false inasmuch as races are only sociocultural constructions. It is time to rid medical research of the highly damaging exercise of searching for supposed racial differences in the biological manifestations of disease. The practice not only (...) condoned but required by the National Institutes of Health of utilizing racial identification as a demographic characteristic with assumed biological implications is at best badly flawed, and at worst unintentionally contributes to perpetuating the fallacy of natural differences between persons of different skin color, which has been used in the past to advance the cause of racial discrimination.

How should we think of perceptual experiences qua dynamic phenomena? Against an increasingly popular Heraclitean approach that frames them as irreducibly dynamic, the present book argues that perceptual experiences may be described in terms of non-dynamic categories, such as properties, relations, and states.

In the context of the end of life, many authors point out how the experience of identity is crucial for the well-being of patients with advanced disease. They define this identity in terms of autonomy, control, or dependence, associating these concepts with the sense of personal dignity. From the perspective of the phenomenology of embodiment, Kay Toombs and other authors have investigated the ways disease can impact on the subjective world of patients and have stressed that a consideration of this (...) personal world can promote understanding and recognition of their experience. Based on the findings of qualitative studies of the perception of dignity and autonomy in patients at the end of life, this analysis assesses concepts such as being-in-the-world in illness, embodiment, lived body versus objective body or the gaze of the other from a Toombsian phenomenological perspective.

En la doctrina del derecho internacional de Hermann Heller el dato fundamental del orden jurídico lo constituye la presencia de unidades decisorias soberanas, individualizadoras del derecho. Heller agrega que, paradojalmente, la existencia del derecho positivo depende de la acción legibus soluta de tales unidades comunitarias. Aunque obligados por “principios jurídicos fundamentales”, los Estados, ante una amenaza que los ponga en riesgo y comprometa, por ende, a la totalidad del orden jurídico, pueden modificar a éste último parcialmente. Así pues, respecto del (...) orden jurídico positivo, el Estado permanece como elemento determinante. Y, dado que en el orden internacional no hay una civitas maxima, sino pluralidad de Estados, serán éstos quienes libremente determinen el derecho internacional público. El Estado nace y perdura como una cierta realidad social y existe como sociedad política –con la legitimidad correspondiente- aun cuando no entable relaciones jurídico-internacionales de ninguna especie. En conclusión, para Heller si el Estado no aparece ni pervive por decisión del derecho internacional, luego tampoco su potestad se origina en una delegación o distribución de funciones emanada de tal orden normativo.

Studies that have explored the wish to hasten death (WTHD) in patients with advanced illness have found that the feeling of being a burden may trigger WTHD. Research suggests that both the feeling and the wish are indicators of multidimensional suffering whose meaning may depend on the patient's biographical background. Therefore, we carried out a systematic review and meta‐ethnography. Fourteen qualitative studies, reported in 16 articles, met the inclusion criteria. The analysis identified two themes: the personal and social dimensions that (...) could help to explain the feeling of being a burden in these patients. These dimensions reveal how this feeling is linked to physical, psychological/emotional, existential and social factors. The feeling of being a burden cannot be understood without considering patients’ personal interpretation of their dependency or care needs, and hence it is also necessary to understand their biographical background. Such an understanding is crucial to inform clinical policies based on the moral duty to provide all patients with humane care. (shrink)

José Luis Bermúdez ha defendido una explicación no-circular de la autoconciencia en virtud de contenidos no-conceptuales de primera persona, explicativa y ontogenéticamente básicos. En este artículo se argumenta que los contenidos no-conceptuales explicativamente básicos caen en el mito de lo Dado; mientras que los contenidos no-conceptuales ontogenéticamente básicos, aunque lo evitan, no constituyen la mejor explicación de la adquisición de capacidades cognitivas.

Como expuso Walter Lippmann en su libro La opinión pública, en sociedades complejas como la nuestra los medios de comunicación de masas construyen un pseudoentorno, a través del cual nos hacen llegar las informaciones necesarias para nuestra vida cotidiana. Pero, los medios de comunicación hacen algo más que informarnos: eligen y organizan jerárquicamente nuestro menú cotidiano de informaciones relevantes. Conjuntamente con los agentes sociales, económicos y políticos prominentes, determinan la agenda de las preocupaciones ciudadanas, colocando en primer plano de la (...) actualidad determinados asuntos y silenciando o soslayando otros. Por esa razón, en la sociedad actual el concepto de opinión pública es incomprensible sin referirnos a la actuación de los medios de comunicación. Pero no se trata únicamente de la labor de los media como vehículos para la información y plataformas para la discusión colectiva. Los media popularizan valores, actitudes y modelos de conducta y su enorme capacidad de influir despierta una razonable preocupación entre los ciudadanos. Esta comunicación analiza siete cuestiones que ilustran las fricciones entre ciudadanía y medios de comunicación en la sociedad contemporánea. (shrink)

En este artículo, el autor ofrece una interpretación de la importancia filosófica actual de la Ilustración escocesa. Después de un amplio repaso de las principales características de este movimiento y del pensamiento de figuras escocesas clave del siglo XVIII, se propone que discusiones del momento en tomo a la naturaleza y perspectivas del progreso en la historia, podrían beneficiarse de una reconsideración crítica de ciertos puntos de vista expuestos por los literati escoceses.

The article presents a critical discussion between the conventional and ultranominalistic interpretations as opposed to the idea of truth discussed by Thomas Hobbes. The alternative offered to these points of view has to do with the defense of a moderate nominalism linked with materialistic commitments. It describes the criterion of truth from a double procedure having in mind the linguistic analysis of the statements as well as its empiric verification. It is hoped to make a contribution to the understanding of (...) the connections between the words and things according with the Hobbes’ perspective. (shrink)

The aim of this paper is to analyze the treatment/enhancement distinction as employed by those against using the newest biomedical technologies for purposes other than those strictly curative. First, we analyze the most common definitions related to treatment, such as health, disease or medicine, showing their limitations and problems. Secondly, we consider three different tasks usually assigned to the treatment/enhancement distinction: 1) to establish what we owe to others, 2) to establish what should be included as part of a medical (...) insurance system and 3) to distinguish the morally permissible from the morally impermissible. We conclude that the treatment/enhancement distinction is a useful, if limited, tool for the first two tasks, but an inadequate one for the third. (shrink)

This article tries to elucidate the Deleuzian project of the reversal of Platonism in relation to that of Nietzsche. To this aim, I have made a predominantly historiographic sketch of the question in both authors. In the case of Nietzsche, I inquired about both the relationship that the reversal of Platonism presents in his philosophy with the problem of nihilism and the evolution that the topic undergoes throughout his vast intellectual production, until it reaches its final formulation. With regard to (...) Deleuze, I offer a broad overview of his work aimed at tracing the subject, from his interpretation of the Nietzschean formulation, as opposed to that of Heidegger, to the meticulous way in which it fits into his own philosophy as a shift of the essence in favour of the event as a source of singularities.
