Adaptive optics are techniques used for processing the spatial resolution of astronomical images taken from large ground-based telescopes. In this work, computational results are presented for a modified curvature sensor, the tomographic pupil image wavefront sensor, which measures the turbulence of the atmosphere, expressed in terms of an expansion over Zernike polynomials. Convolutional neural networks are presented as an alternative to the TPI-WFS reconstruction. This technique is a machine learning model of the family of artificial neural networks, which are widely (...) known for its performance as modeling and prediction technique in complex systems. Results obtained from the reconstruction of the networks are compared with the TPI-WFS reconstruction by estimating errors and optical measurements. The reconstructed wavefronts from both techniques are compared for wavefronts of 153 Zernike modes. For this case, a detailed comparison and grid search to find the most suitable neural network is performed, searching between multi-layer perceptron, CNN and recurrent networks topologies. In general, the best network was a CNN trained for TPI-WFS reconstruction, achieving better performance than the reconstruction software from TPI-WFS in most of the turbulent profiles, but the most significant improvements were found for higher turbulent profiles that have the lowest r0 values.

Descartes posee una visión práctica de la medicina encaminada a la conservación de la salud. Acorde a dicho cometido, los fármacos que hallamos en el Remedia et vires medicamentorum y en su Excerpta anatomica desempeñan un importante papel, en tanto que conforman los instrumentos que posibilitan recuperar la salud ante distintas enfermedades. El presente artículo se propone examinar dichos remedios, dilucidando su estatuto en la medicina cartesiana y su posible origen en farmacopeas clásicas.

La epistemología contemporánea sostiene la imagen de Descartes como un fundamentalista epistemológico clásico, apelando, para ello, a las certezas metafísicas y a la presunta deducción del resto de conocimiento a partir de dichos principios. Con todo, un examen más detallado del proyecto epistemológico cartesiano pone en cuestión esta interpretación. El presente artículo analiza el papel de la deducción y la certeza moral a fin de redefinir el fundamentalismo de Descartes en términos moderados.

RESUMENLa interpretación actual de la ciencia cartesiana ya no concibe ésta como una mera deducción desde los principios metafísicos, sino que reivindica el papel de la experiencia en ella. El presente artículo tratará de dar un paso más, defendiendo que existe una dimensión instrumental en la ciencia cartesiana. Para ello, se analizará la modificación que Descartes realiza en la Dióptrica de la relación artificial-natural y que posibilita una lectura instrumentalista.PALABRAS CLAVEDESCARTES, ARTIFICIAL, NATURAL, INSTRUMENTALISMO, CIENCIAABSTRACTThe current interpretation of the Cartesian science (...) no longer sees it as a mere deduction from the metaphysical principles, but claims the role of experience in it.

Este artículo analiza las estrategias utilizadas por Descartes para «desencantar el mundo», a fin de suprimir los elementos herméticos de las explicaciones científicas cartesianas y someter todos los fenómenos naturales a nuestro control. Para ello, apelo a la distinción entre elementos causales —cualidades ocultas— y sus efectos —efectos admirables— como las dos dimensiones que deben ser incorporadas bajo las explicaciones científicas para garantizar el cálculo de los fenómenos y su dominio.

RESUMEN La interpretación habitual de Descartes sostiene que la nueva ciencia cartesiana es resultado del remplazo, en las explicaciones científicas, de las causas finales y formales por las causas eficientes. Si bien dicha afirmación en líneas generales es correcta, se ha tendido a asumir que las causas eficientes no entrañan problema alguno. Este artículo desea cuestionar dicha asunción, poniendo de manifiesto una serie de problemáticas concernientes a la cognoscibilidad de las causas eficientes. ABSTRACT The common interpretation of Descartes argues that (...) the new science is a result of Cartesian replacement, in scientific explanations, of the final and formal causes by the efficient causes. While this statement is broadly correct, it has tended to assume that efficient causes do not imply any problem. This paper wishes to question this assumption, showing a number of problems concerning the knowability of efficient causes. (shrink)

El hábito cartesiano constituye el elemento clave que posibilita la implantación de determinadas regularidades en mente y cuerpo, facilitando la intervención del sujeto en ambas dimensiones. Así, se observa cómo el hábito juega un importante papel en propuestas cartesianas centrales ― la asunción del método, los prejuicios de la infancia o la educación de las pasiones―, de forma que toda comprensión que se dirija a examinar éstas, deberá referirse previamente al concepto cartesiano de hábito. El presente artículo tratará, en consecuencia, (...) de elucidar el sentido de hábito. Para ello se efectuará una distinción entre los tipos de movimientos encargados de generar distintos hábitos y las diversas formas de memoria que permiten preservar las conexiones sobre las que éste se genera. Una vez ofrecida esta explicación sobre cómo se producen los hábitos, se propondrá una categorización apelando a la distinción establecida por Descartes entre alma y cuerpo. (shrink)

La “conservación de la salud” ha constituido el eje sobre el que se han articulado y evaluado las aportaciones de Descartes a la medicina. Sobre ello, las interpretaciones canónicas se han circunscrito a la terapéutica cartesiana para las enfermedades, obviando otras dimensiones a las que el proyecto médico cartesiano también se dirigió. De ese modo, el presente artículo aborda un segundo sentido de conservación de la salud entendido como “preservación de la salud”, dirigiéndose, para ello, a un análisis de la (...) dieta cartesiana, cuyo empleo evita, según Descartes, la contracción de distintas afecciones. Dicho examen trata de mostrar en qué sentido la dieta posibilita la preservación de la salud, y cómo ésta se justifica apelando a la propia fisiología cartesiana. (shrink)

This article addresses the semiotic problem of how meaning is agentially grounded: how actual meaning is possible and is justifiably supported by agents’ capabilities and purposes. This article is particularly focused on human agential grounding; however, to a great degree, insights presented here can be extended to other living beings. Specifically, agential meaning is examined here inside the framework of agentive semiotics and embodied, situated and enactive cognition theories, in line with the mind-life continuity general thesis. To offer clarity and (...) methodological precision about agential grounding, three explanation categories are proposed: phylogenetic recurrence, the evolutionary basis for corporal/embodied grounding; ontogenetic recurrence, the developmental basis for individual meaning grounding; and collective recurrence, the basis for meaning recognized, attributed and assigned inside social contexts. These recurrences are conceived as three types of general processes that constantly enclose possibilities for purpose and meaning emergence in humans. As a result of these types of recurrences, two categories of human agendas or purposes are also proposed: individual and collective. Finally, remarks about how these categories can be useful for semiotic analysis and further research are suggested. (shrink)

Critical thinking is a complex, dynamic process formed by attitudes and strategic skills, with the aim of achieving a specific goal or objective. The attitudes, including the critical thinking attitudes, constitute an important part of the idea of good care, of the good professional. It could be said that they become a virtue of the nursing profession. In this context, the ethics of virtue is a theoretical framework that becomes essential for analyse the critical thinking concept in nursing care and (...) nursing science. Because the ethics of virtue consider how cultivating virtues are necessary to understand and justify the decisions and guide the actions. Based on selective analysis of the descriptive and empirical literature that addresses conceptual review of critical thinking, we conducted an analysis of this topic in the settings of clinical practice, training and research from the virtue ethical framework. Following JBI critical appraisal checklist for text and opinion papers, we argue the need for critical thinking as an essential element for true excellence in care and that it should be encouraged among professionals. The importance of developing critical thinking skills in education is well substantiated; however, greater efforts are required to implement educational strategies directed at developing critical thinking in students and professionals undergoing training, along with measures that demonstrate their success. Lastly, we show that critical thinking constitutes a fundamental component in the research process, and can improve research competencies in nursing. We conclude that future research and actions must go further in the search for new evidence and open new horizons, to ensure a positive effect on clinical practice, patient health, student education and the growth of nursing science.

La percepción clara y distinta es el elemento sobre el que se asienta la certeza metafísica de Descartes. Con todo, el planteamiento de los argumentos escépticos referidos a la duda metódica cartesiana ha evidenciado la necesidad de hallar una justificación al propio criterio de la percepción clara y distinta. Frente a los intentos basados en la indubitabilidad de la percepción o en la garantía surgida de la bondad divina, se defenderá una justificación alternativa pragmatista.

La pandemia del SARS-CoV-2 ha creado un desafío sin precedentes para la educación. En 2020, como resultado de las medidas para reducir la propagación del SARS-CoV-2, muchas instituciones educativas pasaron del aprendizaje presencial al aprendizaje remoto. Sin embargo, este modelo educativo puede generar estrés y ansiedad adicionales a la ansiedad provocada por la pandemia. Los objetivos del presente estudio fueron: 1) comparar las perspectivas de estudiantes y docentes sobre el número de horas dedicadas a las clases, y 2) determinar las (...) principales dificultades que enfrentan docentes y estudiantes, respectivamente, al pasar al sistema de educación en línea. Para realizar esta investigación se realizó una encuesta online en países de habla hispana, utilizando una muestra de 1.048 participantes anónimos. A través de los datos recopilados. Se analizaron el uso de plataformas, los tipos de equipos, los niveles de angustia y las posibles razones de esta angustia. Esta pandemia es una de las amenazas de salud pública más importantes de la historia reciente y ha afectado nuestras vidas de manera significativa, siendo una de las más importantes la futura adaptación de escuelas, estudiantes y docentes a una nueva forma de aprender.

Since their introduction in Colombia in the '80s for Pablo Escobar’s extravagant zoo, hippos have become an ecological problem around the basin of the Magdalena River. This article proposes an ecosemiotic discourse analysis of different visions of nature enacted by stakeholders and public opinion around the management of hippos in Colombia. Concretely, we focus on three particular discourses and visions of nature: animalista, narco-cultural, and conservacionista. In this article, we present the relevant social and ecological context of Colombia, the visions (...) of nature theory and the impact of such visions on conservation measures regarding so-called invasive species; we describe and analyze the three visions of nature we center on, and present a computational analysis of discourse dynamics and controversies in Twitter between of such visions of nature; and we reflect on possible courses of action and recommendations about addressing the close interrelation of public discourses and ecosystem conservation by proposing an alternative view, based on the biosemiotic framework of semiocide, to the concept of invasive species.

En este texto se elabora un análisis historiográfico, filosófico y teórico en torno a diversas propuestas de caracterización, demarcación, y explicación de la conducta y la cognición. Asimismo, se construyen argumentos para favorecer una comprensión más integral y elaborada de los programas de investigación acerca de la conducta y la cognición. Con este fin, en la primera sección analizaremos y cuestionaremos tres mitos acerca de la historia de la psicología: la tesis de los paradigmas hegemónicos y los reemplazos revolucionarios, la (...) tesis de los paradigmas incomparables, y la tesis que exige un único paradigma dominante como requisito de cientificidad. Dado que estos mitos se derivan de ciertas ideas problemáticas de Kuhn, en la segunda sección ofreceremos una propuesta alternativa basada en la filosofía de la ciencia de Bunge. En las secciones tercera y cuarta exploraremos los significados de las palabras “conducta” y “cognición”, y su relevancia para corregir ciertos malentendidos que obstaculizan los debates entre los programas de investigación conductistas y cognitivos. En las secciones quinta y la sexta, discutiremos algunos mitos acerca del conductismo y del cognitivismo, y en la última sección ofreceremos algunas conclusiones sobre los temas abordados. Las herramientas que analizaremos permiten establecer un debate más racional entre programas de investigación científica, generar puentes de discusión y desarrollo teórico de una manera más integral y completa, y evitar caer tanto en el dogmatismo y la descalificación injustificada, como en las actitudes eclécticas.

El propósito del artículo es explicar el genocidio de la Unión Patriótica en clave de la economía nacional y su ubicación estratégica a partir de una aproximación teórica desde algunos elementos propuestos por Antonio Negri y Michael Hardt. Como conclusión se destaca que el genocidio de la up fue consecuencia de su poderío local, que ponía en riesgo la continuidad de las clases políticas dominantes en razón de sus propuestas como colectivo político. Así mismo, este hecho produjo que a raíz (...) de su origen se construyera sobre ellos un relato negativo de enemigos de la sociedad civil.

This article delineates the notion of conjectural artworks—that is, ways of thinking and explaining formal and relational phenomena by visual means—and presents an appraisal and review of the use of such visual ways in the work of Chilean biologists and philosophers Humberto Maturana and Francisco Varela. Particularly, the article focuses on their recurrent uses of Cellular Automaton, that is, discrete, locally interacting, rule-based mathematical models, as conjectural artworks for understanding the concepts of autopoiesis, structural coupling, cognition and enaction: (i.e. Protobio (...) and Bittorio). Additionally, the article proposes a new model of conjectural artwork based on an extension of cellular automaton: random Boolean networks namely, binary systems with variable local connections. Such model, as it is argued, is useful to connect the theoretical frameworks by Maturana and Varela, especially structural coupling and enaction, with other relevant fields such as biosemiotics’ Umwelt-research and cognitive landscapes in neurodynamics, and to advance and explore the concepts of structurally coupled categorization and generalization.

Las emociones son sin duda un campo de creciente interés y estudio. Sin embargo, son experiencias complejas que incluyen diferentes problemas. Precisamente esta variedad de perspectivas exige mantener el equilibrio de los enfoques y, sobre todo, su orden. La fenomenología ilumina ese orden mediante la descripción de las experiencias emotivas.

In this article, a semiotic approach is proposed to explain how human agents use and give meaning to art in complex contexts. Inspired by the psycho-historical approach on art appreciation, which attempts to embrace psychological and cognitive aspects of art sense-making, as well as the art-historical context dependence of artworks, an extended theory is suggested: an agent's art use and interpretation can be described using three general categories of meaning grounding: phylogenetic recurrence, ontogenetic recurrence and collective recurrence. These categories explain (...) how a certain meaning of a sign is possible and justifiable, supported by human agents' capabilities and purposes. This article also proposes that it is possible to narrate, using such categories of meaning grounding, how different agents enact art, that is, give meaning and act upon art in different circumstances. Finally, I offer some examples about how the model can be used in real art contexts. The objective of this narrative-enactive approach, even though it offers a limited and edited focus, is to offer an orderly and comprehensible method to explain the dynamic nature of art meaning and how biologic, individual and collective grounding and purposes intertwine.

This paper reconstructs the explanation that Descartes offers about two diseases of the mind known in the seventeenth century: phrenitis and lethargy. For this aim, it is exposed, in the first place, how the Cartesian theory of mental representations give an account of the delusions and perceptual hallucinations of the madmen. Thus, Descartes's analysis of phrenitis and lethargy is presented, delving into the Cartesian theory of memory.

Cartesian skepticism represents a fundamental element of the Cartesian method directed to find the metaphysical certainties that securely justify knowledge. Nonetheless, the Cartesian radical doubt has clearly defined limits insofar as it does not extend to the realm of vital praxis. The present paper develops the connection between Cartesian moral certainty and the notion of «practice of life» in order to show how Descartes’ methodological skepticism is framed in the academic tradition rather than in the Pyrrhonian one.

This article explores the role that repetition plays in symbolic healing through a close examination of the speech patterns and actions performed by a healer in a Chol Maya ritual aimed at curing a woman of kisiñ—the “embarrassment-sickness.” The authors examine the repetition of speech patterns in the healing chant and the frequency with which other paralinguistic elements, such as taps, co-occur with the chant verses. The sound patterns generated during the ritual, specifically those created by the rhythmic tapping of (...) the patient's body with a bough bouquet, are yet another form of repetition often overlooked in analyses of healing rituals, which have concentrated on other symbolic elements used by healers. It is argued that the repetition of phrases in parallel verses serves as metapragmatic commentary on the healing process as a restructuring of the patient's body, which has been unstructured by the disease.

IntroductionDuring the Coronavirus pandemic, a set of daily stressors are being experienced, all this affects people’s mental health, leading them to have a set of emotional disturbances. Little is known about how people’s age can influence their emotional well-being in the face of prolonged stress generate by the pandemic.ObjectiveTo clarify the presence of emotional aspects such as emotional expressiveness and the frequency of positive and negative affections in people with different age in times of crisis.MethodsThe final sample included 297 Chileans (...) between 22 and 68 years old, recruited through an online survey with the appropriate written informed consent. The study was carried out when the pandemic was spreading in Chile.ResultsThe findings revealed age differences in emotional expressivity and the type of affections experienced. The expression of emotions was more affected by negative affections, the age and the gender of the people. While the avoidance of this emotional expression, by age and affections both positive and negative. Age was a significant predictor of emotional expressiveness.DiscussionFindings suggests that the associations between both variables, varied according to the age group of the people. Furthermore, this finding proposes that although older people are facing the persistent and serious threat of COVID-19, they show better emotional functioning. Which would help to better understand the interaction of both positive and negative life experiences in times of crisis. (shrink)

BackgroundThe effectiveness of physical activity as an intervention against anxiety disorders and depression is undeniable in clinical psychology. Therefore, the question arose whether these effects also occur when a fear stimulus, like the COVID-19 pandemic, affects otherwise healthy adolescents. Boredom is closely linked to symptoms of fear and anxiety, but the connection between PA, boredom and fear is partly unclear.MethodsA cross-sectional online study was conducted that involved 122 students. Participants were 13–19 years old. The survey was available online from April (...) 27th to May 3rd, 2020. At this time, schools in Germany had already been closed for 6 weeks. A self-report questionnaire was used to measure physical activity, boredom, and fear of COVID-19. A multiple linear regression model was conducted.ResultsThe reported fear of COVID-19 significantly correlates with total PA, quantity of strenuous PA, and boredom. Furthermore, a significant regression equation was found. The variables boredom, PA, and age contribute significantly to predicting the fear of COVID-19 [R2 = 0.127, F = 6.876, p < 0.000], among adolescents.ConclusionOur results indicate that there is an association between PA, boredom and the quarantine experience of adolescents. Students who were physically more active, especially with strenuous intensity, did not feel bored and showed less fear of COVID-19. (shrink)

Physical exercise is seen as the main ally for health promotion, preventing and protecting the organism from several diseases. According to WHO, there is a tendency of constant growth in the elderly population in the coming years. The regular practice of exercises by the elderly becomes relevant to minimize the deleterious effects of the aging process and to increase the fitness index. Recently, the world population started a confrontation against Corona Virus Disease (COVID-19), which is the most significant public health (...) challenge globally. Although social isolation is a reasonable measure in an attempt to stop contamination by COVID-19, this measure has limited the ability of individuals to exercise outdoors or in gyms and health clubs, which increased the risk of developing chronic illnesses related to a sedentary lifestyle. The critical point is that the recent recommendations on exercise prescription to combat the potentially harmful effects of COVID-19 failure to adequately address resistance exercise interventions as home-based exercise strategy. Thus, in this paper, we discussed the physical exercise as medicine if the training status is enough to protect the elderly against COVID-19 infection, about the role of physical activity on immunosuppression. Possible risks for COVID-19 infection, and the old training methods, such as no-load resistance training as possible resistance exercise strategies and high-intensity interval training, as new proposals of home-based exercise interventions, could perform during the current COVID-19 pandemic.

Parental burnout is a unique and context-specific syndrome resulting from a chronic imbalance of risks over resources in the parenting domain. The current research aims to evaluate the psychometric properties of the Spanish version of the Parental Burnout Assessment across Spanish-speaking countries with two consecutive studies. In Study 1, we analyzed the data through a bifactor model within an Exploratory Structural Equation Modeling on the pooled sample of participants obtaining good fit indices. We then attained measurement invariance across both gender (...) and countries in a set of nested models with gradually increasing parameter constraints. Latent means comparisons across countries showed that among the participants’ countries, Chile had the highest parental burnout score, likewise, comparisons across gender evidenced that mothers displayed higher scores than fathers, as shown in previous studies. Reliability coefficients were high. In Study 2, we tested the relations between parental burnout and three specific consequences, i.e., escape and suicidal ideations, parental neglect, and parental violence toward one’s children. The medium to large associations found provided support for the PBA’s predictive validity. Overall, we concluded that the Spanish version of the PBA has good psychometric properties. The results support its relevance for the assessment of parental burnout among Spanish-speaking parents, offering new opportunities for cross-cultural research in the parenting domain. (shrink)

Altered attachment characteristics may disturb the HPA and can even cause changes in the hippocampus. However, it is unknown if that will influence spatial navigation performance, learning and recalling. In this study we pretend to verify if there are differences in spatial navigation learning and was associated with attachment style dimensions of anxiety and close-depend. Sixty-five female participants were recruited and were evaluated using the Adult Attachment Scale-R and tested on a virtual maze navigation task (VMT) at one moment (exploratory (...) trial + 3 trials) and 24h later (3 trials). There was a significant Moment x Trial x Close-Depend interaction for the outcome time, F (2, 126) = 3.807, p = 0.025, with post-hoc analysis indicating that the High Close-Depend group displayed significant improvements between Trial 1 and Trial 3 in the post-test assessment. Conversely, the Low Close-Depend group displayed significant improvements between Trial 1and Trial 3 but on the pre-test assessment. Furthermore, the Low Close-Depend group presented significant better performance in pre-test Trial 3 in comparison to the High Close-Depend group. Thereby, it seems that low comfort with proximity and trust in others is associated with reduced spatial navigation recall, although spatial learning performance was actually superior in these participants. It is possible that reduced exposure to social interaction and meaning relationship may be reduced in the Low Close-Depend group, leading to modifications in hippocampal function and, ultimately, reduced spatial recall. Conversely, participants with high comfort with proximity and trust in others may not display typical spatial learning in the proposed task as they are more willing to freely explore the presented environment.

'We desire all and only those things we conceive to be good; we avoid what we conceive to be bad.' This slogan was once the standard view of the relationship between desire or motivation and rational evaluation. Many critics have rejected this scholastic formula as either trivial or wrong. It appears to be trivial if we just define the good as 'what we want', and wrong if we consider apparent conflicts between what we seem to want and what we seem (...) to think is good. In Appearances of the Good, Sergio Tenenbaum argues that the old slogan is both significant and right, even in cases of apparent conflict between our desires and our evaluative judgements. Maintaining that the good is the formal end of practical inquiry in much the same way as truth is the formal end of theoretical inquiry, he provides a fully unified account of motivation and evaluation.

Background and objectives: Definitions of medical futility, offered by healthcare professionals, bioethicists and other experts, have been rigorously debated by many investigators, but the perceptions of patients of futility have been explored only by a few. Patients were allowed to discuss their concerns about end-of-life care, so that their ideas about treatment futility or utility could be extrapolated by us.Methods: In this cross-sectional study, in-depth, semistructured interviews were conducted with 30 elderly people who were receiving outpatient care in a large, (...) urban Veterans Affairs medical centre in the US. Each of their healthcare providers was also interviewed. Participants were asked to consider four terms commonly used in advance directive forms and to discuss what these terms meant to them. Audiotapes of the open-ended interviews were transcribed and responses were coded and categorised by constant comparison, a commonly used qualitative method.Results: The following four factors were taken into account by the participants when discussing end-of-life interventions and outcomes: expected quality of life; emotional and financial costs of treatment; likelihood of treatment success; and expected effect on longevity.Conclusions: Although the terms “utility” or “futility” were not generally used by the participants, segments of speech indicating their perceptions of these terms were identified. Treatment was not always discussed in the same way by patients and providers, but seemed to reflect the same four concerns. Therefore, it may be fruitful for providers to focus on these concerns when discussing end-of-life treatment options with their patients. (shrink)

Rational Powers in Action presents a conception of instrumental rationality as governing actions that are extended in time with indeterminate ends.
