A great variety of medical conditions are subject to the placebo effect. Although there is mounting evidence to suggest that the placebo effect is related to the expectation of clinical benefit, little is still known about the biochemical bases underlying placebo responses. Positron emission tomography studies have recently shown that the placebo effect in Parkinson’s disease, pain, and depression is related to the activation of the limbic circuitry. The observation that placebo administration induces the release of dopamine in the ventral (...) striatum of patients with Parkinson’s disease suggests a link between the placebo effect and reward mechanisms. In addition to Parkinson’s disease, the placebo-reward model may also apply to other disorders. However, the relative contribution of the different neurotransmitters and neuropeptides that are known to be involved in modulating the activity of the limbic system may be disease-specific. Thus, while the placebo-induced clinical benefit observed in Parkinson’s disease would mostly reflect the release of dopamine in the dorsal striatum, the activation of opioid and serotonin pathways could be particularly implicated in mediating placebo responses encountered in pain and depression, respectively.

La literatura especializada sobre Unamuno ha prestado poca atención a la dimensión del cuidado latente en la obra de este filósofo. El presente estudio ofrece una aportación en ese sentido, para ello parte de los planteamientos éticos contemporáneos relacionados con el cuidado y analiza varios textos de Unamuno a la luz de ese marco teórico. El resultado es una lectura novedosa de su obra donde se identifica la presencia de aspectos vinculados a la eticidad del ser-para-otro, se plasma el ejercicio (...) del cuidado ejercido a través del lenguaje y del tacto, y se profundiza en el alcance ético de la actitud maternal omnipresente en los relatos del bilbaíno.

The self- vs. external-regulation behavior theory, SR-ER Theory model has postulated the Self-Regulation /Non or De-Regulation/Dys-regulation continuum in the person and in their context. The model also generates a behavioral heuristic that allows us to predict and explain the variability of other dependent behavioral variables in a range of scenarios. Consequently, the objective of this study was to validate the different scales prepared on the basis of the theory presented. A total of 469 students voluntarily completed at different times the (...) five questionnaires presented, to give a total of 1,385 completed questionnaires. Using an ex post facto design, descriptive, correlational, confirmatory factorial analysis, reliability, and concurrent validity analyses were carried out. The scales were analyzed individually and as a whole. The results showed the acceptable structure of scale and consistent levels of reliability. The five levels generated by the SR-NR-DR combinatory heuristic that arises from the theoretical model determined significant differences in the levels of the variables analyzed for each psychological context. We discuss the theoretical implications and the implications for the assessment and improvement of the behaviors analyzed in function of the personal and contextual regulation levels evaluated.

El presente trabajo es un estudio descriptivo y con un enfoque sincrónico que da muestra de las deficiencias de los profesores universitarios al redactar textos científicos. Este estudio tiene como objetivo proponer varias acciones de superación para perfeccionar el manejo del lenguaje y el arte de redactar de los docentes de la Universidad de Ciencias Médicas "Dr. Faustino Pérez Hernández" de la provincia Sancti Spíritus que cursan la octava edición de la Maestría en Ciencias de la Educación de la Universidad (...) de Sancti Spíritus "José Martí Pérez". Para darle cumplimiento a este propósito, se aplicaron varios métodos y técnicas de recolección de datos a una muestra seleccionada al azar de informantes y de sus publicaciones, lo que permitió fundamentar la existencia de varias problemáticas en la redacción científica de dichos profesores y la necesidad de implementar formas organizativas básicas del proceso de educación de posgrado para su inmediata y eficaz aplicación. The present work is a descriptive study grounded in a synchronic approach that identifies the deficiencies of university professors when writing scientific texts. This study aims to propose several measures to improve the use of language and the art of writing of teachers of the " Dr. Faustino Pérez Hernández" University of Medical Sciences in Sancti Spíritus, Cuba who are participating in the eighth edition of the Master's Degree in Educational Sciences program at the "José Martí Pérez" University, also located in Sancti Spiritus. Several methods and techniques of data collection were applied to a random sample of informants and their scientific articles. This allowed for the detection of several problems in scientific writing and the need to implement basic organizational forms of postgraduate education for immediate and effective application.

Childhood obesity, linked to a sedentary lifestyle and an unbalanced diet, is one of the main problems in today’s Western societies. In this sense, the aim of the study was to analyze students’ perceived satisfaction in physical education classes with learning strategies and engagement in learning and critical thinking as determinants of healthy lifestyle habits. The study involved 2,439 high school students aged 12–18 years (M= 14.66,SD= 1.78). Structural equation modeling was conducted to analyze the predictive relationships between the study (...) variables. The results showed that teaching, teaching mastery, and cognitive development are precursors to deep thinking on the part of students, indicators of the adoption of healthy lifestyle habits. These results reflect the importance of the methodology adopted by the teacher in order to positively influence the students’ habits. (shrink)

The gene regulation function (GRF) provides an operational description of a promoter behavior as a function of the concentration of one of its transcriptional regulators. Behind this apparently trivial definition lies a central concept in biological control: the GRF provides the input/output relationship of each edge in a transcriptional network, independently from the molecular interactions involved. Here we discuss how existing methods allow direct measurement of the GRF, and how several trade‐offs between scalability and accuracy have hindered its application to (...) relatively large networks. We discuss the theoretical and technical requirements for obtaining the GRF. Based on these requirements, we introduce a simplified and easily scalable method that is able to capture the significant parameters of the GRF. The GRF is able to predict the behavior of a simple genetic circuit, illustrating how addressing the quantitative nature of gene regulation substantially increases our comprehension on the mechanisms of gene control.

In this article are treated, in general strokes, the methodological foundations of the Diccionario de conceptos políticos y sociales de la España de los siglos XIX y XX which has been published recently under the direction of the above mentioned editors. This dictionary in which nearly 200 authors of different Spanish universities and centres of research have collaborated collects more than 100 articles. It is partly inspired by the German Begriffsgeschichte. Its editors, however, have also taken into account the contribution (...) of the famous school of Cambridge by adapting the influences of several methodological currents to the specific claims of their work, i. e. to the elaboration of a dictionary which, on the basis of a huge volume of sources, pretends to cartograph, in an alphabetical order, the principal ideological lines – the discoursive and conceptual ones – of the Spanish 19th century. The article ends with a discussion of certain difficulties and aspects which are treated controversally in the intellectual history. It also claims to give a reflexion on the suitability and meaning which can – in the actual situation of the social sciences – pretend to determine the studies of political languages, especially the basic essays concerning the comparative history of political and social thinking under a conceptual perspective.

La diversidad cultural en la sociedad y en las aulas es una realidad patente que hay que tener en cuenta y no obviar. La investigación en el campo de las actitudes desarrolladas por parte de los agentes educativos se hace inexorablemente pertinente y necesaria para la construcción de una sociedad futura libre de conflictos innecesarios. En este estudio se han analizado las actitudes familiares mediante entrevista semiestructurada. Se realizó un análisis cualitativo y cuantitativo, obteniendo el perfil sobre pensamiento en torno (...) a la diversidad cultural de progenitores e hijos. El grado de concordancia de dichas actitudes queda reflejado en el análisis de los resultados, apreciando desconocimiento de grupos culturalmente diversos, ventajas de enriquecimiento personal, convicción sobre la necesidad de integrar tanto a los estudiantes como a sus familias, preparación del profesorado y fomento de unas relaciones óptimas entre alumnos, docentes y familias. No obstante, existen divergencias en la función de la escuela con relación a las conductas, creencias, tradiciones y dificultades, y a la formación de los docentes para superarlas y para el tratamiento de la diversidad.

La crítica de Feuerbach concibe el fenómeno religioso como una manifestación efectiva de la autoconciencia humana. Partiendo de este supuesto, el presente artículo tiene como objeto contextualizar, a la luz de un desarrollo histórico, el humanismo propuesto por el autor como siguiente estadio del proceso de autoconocimiento humano. Dicha propuesta implicaría necesariamente el reconocimiento de los mecanismos de enajenación implícitos en la religión y, en definitiva, su superación. Al desembarazarse de las especulaciones propias de la fe, la reducción de la (...) teología a la antropología despojaría a la realidad de todo elemento sobrenatural y supondría un avance significativo en pos de la plenitud humana.

Open Letter to Comrade Žižek is an attempt to question and highlight some incongruous points that Slavoj Žižek, one of the greatest critics of capitalism and its ideological effects in the contemporary world, expressed in his latest books about the Pandemics. The text focuses in the economic, political, social and cultural consequences of Žižek’s position and goes further in developing another position related to the spread of COVID-19 and the preventive measures to fight it.

Este artículo pretende mostrar la crítica de Hume a la tradicional oposición entre razón y pasión. Frente al modelo de razón geométrica y de metafísica esencialista de cuna platónico-pitagórica, Hume apuesta por otra fuente de certezas «a la medida de lo humano », capaz de superar las «miserias» —limitaciones y excesos ideológicos— de esa razón demostrativa e intuitiva. En las cuestiones de hecho y en la moral no hay autoevidencias geométricas. Sólo un nuevo y más amplio modelo de racionalidad (...) será válido para reflexionar sobre esas cuestiones. Junto a la razón matemática y sus certezas plenas, habría otra forma de certeza igualmente válida, pero mucho más útil, que Hume descubre arraigada en la dimensión pasional humana. Alumbra así «lo otro de la razón» en el interior de la misma, anticipando importantes ideas de autores contemporáneos críticos de la «razón carismática» moderna. (shrink)

Este artículo aborda las fuentes antiguas del problema medieval de los universales em relación con la tradición filosófica posterior. Nos enfocamos en la Antigüedad Tardía como el marco dentro del cual se forja el problema de los universales y repasamos algunos acuerdos básicos del mundo académico, así como los tópicos actualmente debatidos. Sobre esa base, tratamos la doctrina de los universales de Porfirio, tanto en la Isagogé como en otras obras. En cuanto a Boecio, señalamos sorprendentes diferencias, no solo entre (...) su comentario a las obras lógicas de Aristóteles y su Consolación de la Filosofía, sino también dentro del corpus lógico mismo. El resultado es que ambos autores son abstraccionistas pero al mismo tiempo negocian con la metafísica realista platónica. (shrink)

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.

Este trabajo intenta analizar las tensiones e interrelaciones entre el paradigma del reconocimiento y el paradigma de la redistribución. En concreto se analiza críticamente la obra de Nancy Frazer. En este sentido, se propone el paradigma de la inclusión, para un tercer ámbito, el de la política. Este paradigma se basaría en el ideal de la igual dignidad y la tricotomía inclusión/exclusión/participación. También se plantean reservas a la noción de paridad participativa, que según Fraser, hace conmensurables todas las demandas de (...) justicia. La conclusión es que redistribución y reconocimiento son irreductibles, están interrelacionados y en tensión. Para los casos de soluciones contrapuestas, se propone la noción de inconmensurabilidad que sostienen los defensores del pluralismo de valores -Berlin,Gray-. En casos de conflicto, redistribución y reconocimiento abocarían a una respuesta similar a cómo se debería resolver un dilema. (shrink)

The purpose of this article is to explore the concept of Philosophy within the works written by Wittgenstein if we take into account the ambivalent sense of the term phármakon. Thus, it will be outlined a contest of paradoxes between, on the one hand, healthiness, sanity, and the adaptable confidence produced by western rationality materialized into objective science, and, on the other hand, sickness, insanity, the world of perplexities, and the realm of desire and death, essential to philosophical thought. Bearing (...) in mind last Wittgenstein’s approaches, we will understand the Tractatus both critical to the deficiencies of western Reason and imprisoned within them. But the “enchanting” power of western Reason, conducting to identify rationality and scientificity in that work, will be conjured in the last Wittgenstein through the opening of plural realms of rationality and of discourses. In this way, philosophical questions will be rescued from silence and absurdity. (shrink)

We are going to analyse the issue of alterity in the philosophy of Miguel de Unamuno through the study of Abel Sánchez. In this nivola, Unamuno examines the concept of envy and establishes the bases of a theory of alterity based on the specular relationship with the other, which it is constituted by the scarcities of the one who looks. We will also look at what are the philosophical premises of this narration, in which way it is linked with the (...) organic philosophy of Unamuno, and what its relationship with the theatre piece El Otro is, released more than a decade after but of a quite similar subject. Finally, we will outline a possible theory of the alterity by Unamuno that it is formulated through the fraternity and altruistic help. (shrink)

En primer lugar, se estudian los elementos de retribución, reciprocidad y altruismo implicados. En segundo lugar, se desarrollan algunas de las habituales críticas sobre esta Regla y dos argumentos de defensa. Finalmente, se aplica el análisis sobre esta Regla a la resolución de cuatro casos controvertidos. La intención es considerar que la Regla de Oro forma parte de (...) la ética de la alteridad.ABSTRACT: This article analyses the Golden Rule of Humanity, which is the common moral denominator of the majority of religions and cultures. Firstly, it looks at the elements of retribution, reciprocity and altruism as implied. Secondly, it develops some of the common criticisms of this Rule and two arguments of defence.

The SRL vs. ERL theory has shown that the combination of levels of student self-regulation and regulation from the teaching context produces linear effects on achievement emotions and coping strategies. However, a similar effect on stress factors and symptoms of university students has not yet been demonstrated. The aim of this study was to test this prediction. It was hypothesized that the level of student self-regulation (low/medium/high), in interaction with the level of external regulation from teaching (low/medium/high), would also produce (...) a linear effect on stress factors and symptoms of university students. A total of 527 undergraduate students completed validated questionnaires about self-regulation, regulatory teaching, stress factors and symptoms. Using an ex post facto design by selection, ANOVAs and MANOVAs (3 x 3; 5 x 1; 5 x 2) were carried out. The results confirmed that the level of self-regulation and the level of regulatory teaching jointly determined the level of stress factors and symptoms of university students. Once again, a five-level heuristic of possible combinations was configured to jointly determined university students’ level of academic stress. We concluded that the combination of different levels of student regulation levels and regulation from teaching process jointly determines university students’ level of academic stress. The implications for university students’ emotional health, stress prevention and well-being are established. (shrink)

The aim of this research was to determine the degree to which undergraduate students’ learning approach, academic achievement and satisfaction were determined by the combination of an intrapersonal factor (self-regulation) and a interpersonal factor (contextual or regulatory teaching). The hypothesis proposed that greater combined regulation (internal and external) would be accompanied by more of a deep approach to learning, more satisfaction and higher achievement, while a lower level of combined regulation would determine a surface approach, less satisfaction and lower achievement. (...) Within an ex post facto design by selection, 1036 university students completed validated questionnaires using an online tool. Several multivariate analyses were conducted. Results showed that the combination of self-regulation and external regulation can be ordered as levels along a five-point scale or heuristic. These levels linearly determine type of learning approach, academic achievement and satisfaction. Implications are established for quality and improvement of the teaching and learning process at university. (shrink)
