Educar implica, en gran medida, transgredir la flecha del tiempo y actuar a modo de contratiempo. Los profesores saben bien que, en numerosas ocasiones, para asegurar el éxito de su acción, deben a menudo "perder tiempo" dejándose paradójicamente llevar por él. El conocimiento del tiempo educativo nos introduce en el estudio de este peculiar contratiempo que, a diferencia del tiempo objetivo, predecible y cronométrico que sirve para racionalizar las actividades pedagógicas, permite a los educadores impedir que en educación el tiempo (...) pase, se consuma sin más, fluya o simplemente suceda. De ahí que la autora plantee las relaciones tiempo y educación desde una perspectiva más integradora, incorporando para ello los múltiples tiempos que confluyen en la realidad educativa junto aquéllos que confieren legitimidad al proyecto educativo. La escuela ha venido recreando un modelo no normativo tiempo -básicamente predictivo y probabilístico- y ha aplicado una racionalidad ahistórica que dificulta la emergencia del sujeto al que se dirige y el modelo de sociedad hacia la que se proyecta. En la actualidad se plantea la necesidad de educar desde una nueva perspectiva ética que integre el tiempo como categoría normativa de acción. Educar hoy para mañana exigirá, en este sentido, atender a dos lógicas temporales: impregnar de historicidad la dimensión de sentido de todo proyecto educativo y planificar las acciones pedagógicas de acuerdo con una nueva tecnología temporal que incorpore la incertidumbre, la complejidad, la interdependencia y la sostenibilidad temporal.

El propósito general de este estudio es ofrecer un marco de análisis integrador sobre la arquitectura emocionalde la educación y sus implicaciones para el diseño de acciones educativas pertinentes en los procesos de formaciónhumana. De modo específico, se analizan los componentes y mecanismos emocionales implicados en los procesoseducativos que han probado su efectividad. A tal fin, se ha aplicado un enfoque analítico basado en una revisióndocumental a partir de estudios científicos y humanísticos. Las preguntas que han guiado este estudio han (...) sido: ¿aqué nos referimos cuando hablamos de emoción en las ciencias de la educación?, ¿qué componentes y mecanismosdefinen la arquitectura emocional de los procesos educativos? Se infiere que la arquitectura emocional de laeducación posee un carácter pluridimensional, pues concierne a realidades orgánicas, psíquicas y socioculturales;asimismo, que los componentes esenciales para educar y aprender tienen en las emociones sus instrumentosmás destacados, entre ellos, deseo y entusiasmo. Como mecanismos emocionales más relevantes se encuentranla implicación —del enseñante y el aprendiz— la resonancia y la proximidad emocional. Las implicacionespedagógicas son apostar por una educación afectiva que integre el aprendizaje del bienestar y del dolor, y laapuesta de metodologías experienciales, participativas y artísticas —especialmente dramáticas o escénicas— ydispositivos de acompañamiento para los profesionales de la educación y los estudiantes.

Recent arguments claim that behavioral science has focused – to its detriment – on the individual over the system when construing behavioral interventions. In this commentary, we argue that tackling economic inequality using both framings in tandem is invaluable. By studying individuals who have overcome inequality, “positive deviants,” and the system limitations they navigate, we offer potentially greater policy solutions.

Dentro del epistolario de Francisco Romero, que permanece inédito, se analizan las cartas que intercambió con el filósofo personalista Edgar S. Brightman (1884-1953), como así también se alude a otros representantes dentro del movimiento en EEUU. Este escrito se apoya en la hipótesis del interés compartido por esta corriente de ideas dentro de los años que van desde la II Guerra Mundial hasta los inicios de la llamada Guerra Fría. Se alude también al propósito de ambos corresponsales por acercar (...) la filosofía estadounidense y la desarrollada en América Latina. Las cartas en el repositorio se extienden entre 1939 y 1952. Se incluye como anexo la nota necrológica sobre Brightman redactada por José Vasconcelos con el fin de mostrar que su filosofía interesaba también en otros países latinoamericanos. Within the unpublished epistolary collection of Francisco Romero, this work analyses the letters that were exchanged with the personalist philosopher Edgar S. Brightman (1884-1953), and it also refers to others representative philosophers inside the American Personalist movement. The hypothesis is that both maintain a mutual interest for these ideas during World War II until the beginnings of the so called Cold War. It also refers to the purpose of both correspondents to come closer American and Latin American philosophy. The letters in the collection were written between 1939 and 1952. This paper includes as appendix the obituary authored by José Vasconcelos about Brightman to show that his philosophy was of interest in other Latin American countries. (shrink)

El libro de Alex Ibarra, Filosofía chilena. La tradición analítica en el periodo de la institucionalización de la filosofía, plantea la discusión sobre las líneas filosóficas, demostrando la existencia de cierta tradición analítica en Chile. A partir de allí, reflexionamos en torno a los procesos de constitución del campo de la filosofía en Chile como una historia atravesada por la necesidad de préstamos y cruces que impiden una delimitación clara de sus límites, lo que tornaría necesaria la atención a (...) ciertas políticas de la lectura que el libro soslaya. La productividad de la filosofía producida en Chile surgiría gracias -y no pese- a su inscripción en sus tiempos y espacios, a partir de recepciones cuya ausencia de retraso no impide el gesto de cierto re-trazo de lo leído. Alex Ibarra's exposition in his book Filosofía chilena. La tradición analítica en el periodo de la institucionalización de la filosofía, places the discussion on the philosophical traditions, showing the existence of a certain kind of analytical tradition in Chile. From there, we expose the processes of constitution of the field in Chile as a history crossed by the need of importations and intersections that contest the clear delimitation of its boundaries, what makes necessary the attention of the politics of readings that the book avoid. The productivity of the philosophic production in Chile, arises thanks to -but not in spite of- its inscription in its age/times and spaces, coming from its receptions and its differences. (shrink)

In the present work, we will analyze the concept of intuition mainly in relation to the epistemological and the metaphysical theses of Schopenhauerian theory. In the first section, we will discuss the central axes of Schopenhauer’s metaphysical system, especially regarding the concept of will (Wille) and the relationship that this entails with his theory of knowledge. Then, we will examine the difference that the German philosopher establishes between representative —or mediated— rational knowledge and direct —or immediate— intuitive knowledge. Likewise, we (...) will trace at first the theses and the fundamental problems of the dualism of representation and we will furtherly establish the problem of the intuition of one’s own body. Finally, we will consider the scope and the limits of intuition, as well as its different variants: mainly aesthetic intuition and its culmination in mystical intuition. (shrink)

Transformar el modo de vida individual es necesario para abordar la crisis ecosocial, y resulta perentorio que las políticas comprometidas con su resolución promocionen una capacidad individual de acción ecosocial. Sin embargo, parece que cierta brecha motivacional está obstaculizando la transformación del modo de vida individual. A fin de dar respuesta a esta brecha, ensayamos una mixtura del enfoque de las capacidades con las teorías de Hartmut Rosa. Argumentamos que la resonancia natural funge de factor personal de conversión necesario, si (...) bien no suficiente, para la capacidad de acción ecosocial; y que una política que promocione la resonancia natural se adecuaría también a los requisitos impuestos al desarrollo humano tanto por el enfoque de las capacidades como por la sostenibilidad.

Background: Eye movement desensitization and reprocessing [EMDR] is an innovative, evidence-based and effective psychotherapy for post-traumatic stress disorder [PTSD]. As with other psychotherapies, the effectiveness of EMDR contrasts with a limited knowledge of its underlying mechanism of action. In its relatively short life as a therapeutic option, EMDR has not been without controversy, in particular regarding the role of the bilateral stimulation as an active component of the therapy. The high prevalence of EMDR in clinical practice and the dramatic increase (...) in EMDR research in recent years, with more than 26 randomized controlled trials published to date, highlight the need for a better understanding of its mechanism of action. Methods: We conducted a thorough systematic search of studies published until October 2017, using PubMed, ScienceDirect, Web of Knowledge and Scopus databases that examined the mechanism of action of EMDR or provided conclusions within the framework of current theoretical models of EMDR functioning. Results: Seventy-five studies were selected for review and classified into three overarching models; (i) psychological models (ii) psychophysiological models and (iii) neurobiological models. The evidence available from each study was analysed and discussed. Results demonstrated a reasonable empirical support for the working memory hypothesis and for the physiological changes associated with successful EMDR therapy. Recently, more sophisticated structural and functional neuroimaging studies using high resolution structural and temporal techniques are starting to provide preliminary evidence into the neuronal correlates before, during and after EMDR therapy. Discussion: Despite the increasing number of studies that published in recent years, the research into the mechanisms underlying EDMR therapy are still in its infancy. Studies in well-defined clinical and non-clinical populations, larger sample sizes and tighter methodological control are further needed in order to establish firm conclusions. (shrink)

Organisations have implemented intensive home-based teleworking in response to global COVID-19 lockdowns and other pandemic-related restrictions. Financial pressures are driving organisations to continue intensive teleworking after the pandemic. Understanding employees’ teleworking inclinations post COVID-19, and how these inclinations are influenced by different factors, is important to ensure any future, more permanent changes to teleworking policies are sustainable for both employees and organisations. This study, therefore, investigated the relationships between the context of home-based teleworking during the pandemic, productivity perceptions during home-based (...) teleworking, and employees’ future teleworking inclinations beyond the pandemic. Specifically, the study examined whether pandemic-teleworking conditions related to the job, and the physical and social environments at home, influenced employees’ FTI, and if perceptions of improved or reduced productivity mediated these relationships. Data were collected during April and May 2020 with a cross-sectional online survey of teleworkers in Germany, Switzerland, the United Kingdom, and other countries during the first COVID-19 lockdowns. Reported FTI were mixed. Most participants reported wanting to telework more post-pandemic compared to before the pandemic; however, 18% wanted to telework less. Hierarchical multiple regression analysis revealed that some teleworking conditions were positively associated with FTI. Other teleworking conditions were not associated with FTI. Perceived changes in productivity mediated the relationship between work privacy fit and FTI. Findings highlight the role of work privacy fit and job demands in influencing pandemic productivity perceptions and teleworking inclinations post-pandemic. Results raise questions about the suitability and sustainability of home-based teleworking for all staff. As organisations plan to increase the proportion of teleworking post-pandemic, this study suggests there is a need to support employees who perceived their productivity to be poor while home-working during the pandemic.

The Western world is experiencing a resurgence of interest in the therapeutic potential of psychedelics, most of which are derived from plants or fungi with a history of Indigenous ceremonial use. Recent research has revealed that psychedelic compounds have the potential to address treatment‐resistant depression and anxiety, as well as post‐traumatic stress disorder and addictions. These findings have contributed to the decriminalization of psychedelics in some jurisdictions and their legalization in others. Despite psychedelics’ opaque legal status, numerous companies and individuals (...) are profiting from speculative investments with few, if any, benefits accruing to Indigenous Peoples. In this paper, we suggest that the aptly named “psychedelic renaissance,” like the European Renaissance, is made possible by colonial extractivism. We further suggest that Indigenous philosophical traditions offer alternative approaches to reorient the “psychedelic renaissance” towards a more equitable future for Indigenous Peoples, psychedelic medicines, and all our relations.

In the field of clinical practice, there does not seem to be too much contention about what schizophrenia is, at least from a high level. After all, there are various diagnostic systems and guidelines, all of which point toward schizophrenia as a psychotic syndrome which likely forms a continuum with other psychotic disorders. It may sound obvious that, according to the current definitions, the major commonality between schizophrenia and all other psychoses is psychotic symptoms; more precisely, delusions and hallucinations. Any (...) description, or ‘phenomenology’ as most clinicians view it, can be found in these diagnostic manuals. However, is there anything at all that sets schizophrenia apart from the other...

In this article, I give a counterexample to a claim made in that empirically equivalent theories can often be regarded as theoretically equivalent by treating one as having surplus structure, thereby overcoming the problem of underdetermination of theory choice. The case I present is that of Lorentz's ether theory and Einstein's theory of special relativity. I argue that Norton's suggestion that surplus structure is present in Lorentz's theory in the form of the ether state of rest is based on a (...) misunderstanding of the role that the ether plays in Lorentz's theory, and that in general, consideration of the conceptual framework in which a theory is embedded is vital to understanding the relationship between different theories.

We address a recent proposal concerning ‘surplus structure’ due to Nguyen et al.. We argue that the sense of ‘surplus structure’ captured by their formal criterion is importantly different from—and in a sense, opposite to—another sense of ‘surplus structure’ used by philosophers. We argue that minimizing structure in one sense is generally incompatible with minimizing structure in the other sense. We then show how these distinctions bear on Nguyen et al.’s arguments about Yang-Mills theory and on the hole argument.

There has been much debate recently on the question whether essence can explain modality. Here, I examine two routes to an essentialist account of modality. The first is Hale's argument for the necessity of essence, which I will argue is — notwithstanding recent attempted defences of it — invalid by its very structure. The second is the proposal that it is essential to essential truth that it is necessary. After offering three possible versions of the view, I will argue that (...) each fails to provide a metaphysical explanation of necessity in terms of essence. (shrink)

Patients with psychotic disorders experience a range of reality distortions. These often include auditory-verbal hallucinations, and thought insertion to a lesser degree; however, their mechanisms and relationships between each other remain largely elusive. Here we attempt to establish a integrative model drawing from the phenomenology of both AVHs and TI and argue that they in fact can be seen as ‘spectra’ of experiences with varying degrees of agency and ownership, with ‘silent and internal own thoughts’ on one extreme and ‘fully (...) external and clearly audible voices’ in the absence of a speaker on the other. We believe a spectral model will add emphasis to the continuity of experience and help to better understand how one type of psychotic symptom may interact with another, and put forward the argument that the experience of TI itself is not sufficient to classify as a delusion. In addition we aim to discuss some of the conceptual issues surrounding AVHs and TI with first-person accounts and current philosophical and neuropsychological theories in mind. We propose that the mechanisms behind AVHs and TI are more complex than source-monitoring deficits; indeed, to understand such phenomena one must appreciate that their very ‘existence’ and ‘reality’ as experienced by the individual have much deeper implications and meaning, both philosophically and clinically.

En este artículo buscamos mostrar que, tanto en la filosofía de Schopenhauer como también en la de Bergson, la experiencia estética se constituye como el paradigma del conocimiento intuitivo. A diferencia de lo que establece la teoría kantiana, para Schopenhauer y Bergson la intuición no sólo es la única forma de conocimiento inmediato, sino que no necesita de conceptos para aprehender aquello dado en la sensibilidad. Asimismo, puesto que actualmente no encontramos demasiada literatura sobre la influencia de Schopenhauer en la (...) filosofía de Bergson, dicho análisis pretende contribuir al establecimiento de los posibles vínculos entre ambas teorías.

We argue that several apparently distinct responses to the hole argument, all invoking formal or mathematical considerations, should be viewed as a unified “mathematical response.” We then consider and rebut two prominent critiques of the mathematical response before reflecting on what is ultimately at issue in this literature.

Schizophrenia as a pathology of self-awareness has attracted much attention from philosophical theorists and empirical scientists alike. I view schizophrenia as a basic self-disturbance leading to a lifeworld of solipsism adopted by the sufferer and explain how this adoption takes place, which then manifests in ways such as first-rank psychotic symptoms. I then discuss the relationships between these symptoms, not as isolated mental events, but as end-products of a loss of agency and ownership, and argue that symptoms like thought insertion (...) and other ego-boundary disorders are by nature a multitude of paradoxes created by a fragmented awareness. I argue that such fragmentation does not always require or lead to a delusional elaboration as the definitive feature of its phenomenology, and present reasons for the role of the first-person pronoun as a mere metaphor used to represent the patient’s bizarre experiences where sensory perception and thinking processes converge. Further, I discuss the initi... (shrink)

Universities increasingly play an important role in entrepreneurship, which has contributed to gender equality in the business world. The aim of this study is to establish a causal model of entrepreneurial intentions and explore it by gender, based on the dimensions of the Theory of Planned Behavior, and how these are mediated by the individuals’ resilience and psychological well-being. The previous work experience was considered as one of the control variables, in order to analyze whether this influence the entrepreneurial intention. (...) With a convenience sample of 644 Portuguese students, Structural Equation Modeling was used. For a better understanding, multivariate analyses were performed and each one was individually reported, and for appropriate comparisons by gender, the t-student test was used. The comparison of means, between genders, showed that there are differences only between perceived behavioral control, subjective norm, and entrepreneurial intention, with women scoring the highest values, and psychological well-being, with men scoring the higher. A serial mediation path was performed, and psychological resilience was found to mediate a significant effect between perceived behavioral control and intention in females, but not in males. It also mediates a significant effect between attitude and intention in females, but not in males. These results show that attitude is a determining factor for females to become entrepreneurs. Finally, after discussing the results, theoretical and practical contributions are analyzed, with regard to the field of entrepreneurship in Portugal, and alternatives are pointed out for a more entrepreneurial future, reinforcing the role of higher education institutions.

Se propone un método paradójico para el análisis del Derecho. Este método de conocimiento consiste en una mirada a la complejidad del fenómeno jurídico, presentando sus aspectos complejos en forma de aparentes contradicciones. No son contradicciones reales, sino elementos complejos que, al constatarlos como0 dándose conjuntamente, nos permite dotar de profundidad nuestra reflexión. Hay diferentes maneras de definir la paradoja, pero aquí nos centramos en las cualidades literarias, retóricas y filosóficas que ofrece el tipo o tipos de paradoja utilizados, de (...) forma magistral, por el escritor inglés G.K. Chesterton. De las funciones de las paradojas (desde esta perspectiva, pero no solamente) son especialmente útiles para el análisis jurídico: criticar el sistema de pensamiento y abrir a la realidad. La primera se relaciona con el Derecho porque este siempre está bajo la amenaza del formalismo. La segunda se relaciona con él porque el Derecho es un fenómeno humano, de forma que, cuando hablamos de Derecho, estamos analizando la realidad compleja de la persona humana. Esta nos e puede reducir a una sola de sus dimensiones, y por ello es necesaria la paradoja, para equilibrar los distintos enfoques del análisis. Tras explicar todo esto, se procede en el artículo a sugerir siete paradojas que muestran la complejidad del fenómeno jurídico y pretenden ser retos al pensamiento. (shrink)

It is common in psychiatry and other sciences to describe an individual or a type of individual in terms of its disposition to manifest specific effects in a particular range of circumstances. According to one understanding, dispositions are statistical regularities of an individual or type of individual in specific circumstances. According to another understanding, dispositions are properties of individuals in virtue of which such regularities hold. This entry considers a number of ways of making each of these senses of disposition (...) more precise while discussing a number of dangers lurking in careless use of the concept of a disposition.

This book provides an up-to-date revision of materialism’s central tenets, its main varieties, and the place of materialistic philosophy vis a vis scientific knowledge. Materialism has been the subject of extensive and rich controversies since Robert Boyle introduced the term for the first time in the 17th century. But what is materialism and what can it offer today? The term is usually defined as the worldview according to which everything real is material. Nevertheless, there is no philosophical consensus about whether (...) the meaning of matter can be enlarged beyond the physical. As a consequence, materialism is often defined in stark exclusive and reductionist terms: whatever exists is either physical or ontologically reducible to it. This conception, if consistent, mutilates reality, excluding the ontological significance of political, economic, sociocultural, anthropological and psychological realities. Starting from a new history of materialism, the present book focuses on the central ontological and epistemological debates aroused by today’s leading materialist approaches, including some little known to an anglophone readership. The key concepts of matter, system, emergence, space and time, life, mind, and software are checked over and updated. Controversial issues such as the nature of mathematics and the place of reductionism are also discussed from different materialist approaches. As a result, materialism emerges as a powerful, indispensable scientifically-supported worldview with a surprising wealth of nuances and possibilities. (shrink)

Macroscopic irreversible processes emerge from fundamental physical laws of reversible character. The source of the local irreversibility seems to be not in the laws themselves but in the initial and boundary conditions of the equations that represent the laws. In this work we propose that the screening of currents by black hole event horizons determines, locally, a preferred direction for the flux of electromagnetic energy. We study the growth of black hole event horizons due to the cosmological expansion and accretion (...) of cosmic microwave background radiation, for different cosmological models. We propose generalized McVittie co-moving metrics and integrate the rate of accretion of cosmic microwave background radiation onto a supermassive black hole over cosmic time. We find that for flat, open, and closed Friedmann cosmological models, the ratio of the total area of the black hole event horizons with respect to the area of a radial co-moving space-like hypersurface always increases. Since accretion of cosmic radiation sets an absolute lower limit to the total matter accreted by black holes, this implies that the causal past and future are not mirror symmetric for any spacetime event. The asymmetry causes a net Poynting flux in the global future direction; the latter is in turn related to the ever increasing thermodynamic entropy. Thus, we expose a connection between four different “time arrows”: cosmological, electromagnetic, gravitational, and thermodynamic. (shrink)

I discuss the recent claims made by Mario Bunge on the philosophical implications of the discovery of gravitational waves. I think that Bunge is right when he points out that the detection implies the materiality of spacetime, but I reject his identification of spacetime with the gravitational field. I show that Bunge’s analysis of the spacetime inside a hollow sphere is defective, but this in no way affects his main claim.
