Purpose: This systematic review aimed to analyze the impact that the COVID-19 lockdown had on the amount of physical activity performed by university students.Materials and Methods: A systematic electronic search for studies providing information regarding physical activity levels pre and during COVID-19 pandemic in university students was performed up to 20th October 2020 in the databases Cochrane Library, PubMed, SPORTDiscus, and Web of Science. The risk of bias of external validity quality of included studies was assessed by means of those (...) the Newcastle-Ottawa Scale. The quality of the evidence for main outcomes was graded using the Grading of Recommendations Assessment, Development and Evaluation approach.Results and Conclusions: A total of 10 studies were selected. Physical activity levels were assessed by means of questionnaires and accelerometer. Risk of bias was regarded as low and high in six and four investigations, respectively. The quality of evidence was downgraded to low. A significant reduction of physical activity levels were observed in 9 studies. Compared to pre-lockdown values, five studies showed a reduction of light/mild physical activity between 32.5 and 365.5%, while seven studies revealed a reduction of high/vigorous physical activity between 2.9 and 52.8%. Walking, moderate, vigorous, and total physical activity levels have been reduced during the COVID-19 pandemic confinements in university students of different countries. Despite of the reductions, those who met the current minimum PA recommendations before the lockdown generally met the recommendations also during the confinements. (shrink)

Against the common historiographic narratives of evolutionary biology, the first decades of the 20th century were theoretically far richer than usually assumed. This especially refers to the hitherto neglected role that early theoretical biologists played in introducing visionary research perspectives and concepts before the institutionalization of the Modern Synthesis. Here, we present one of these scholars, the German theoretical biologist and ecomorphologist Hans Böker, by reviewing his 1935 paper “Artumwandlung durch Umkonstruktion, Umkonstruktion durch aktives Reagieren der Organismen”, published in the (...) inaugural volume of the journal Acta Biotheoretica. While largely forgotten today, this work represents a melting pot of ideas that adumbrate some of today’s most lively debated empirical and conceptual topics in evolutionary biology: the active role of organisms as actors of their own evolution, environmental induction and phenotypic plasticity, genetic assimilation, as well as developmental bias. We discuss Böker’s views on how species change through "Umkonstruktion," and how such reconstruction is exerted through active reactions of organisms to environmental perturbations. In addition, we outline the aims and wider context of his "biological comparative anatomy," including Boker’s reprehensible political affiliation with the Nazi Party. Finally, we highlight some of the historical reasons for why Böker’s views did not have a larger impact in evolutionary biology, but we also recount some of the direct and indirect legacies of his approach in research areas such as ecomorphology and EvoDevo. Böker’s paper is available as supplementary material in the online version of this article, as part of the journal's "Classics in Biological Theory" collection; the first translation of the paper into English, by Alexander Böhm and Jan Baedke, is also being published in this volume.

Emotional regulation, understood as the skills and strategies needed to influence and/or modify the emotional experiences, has a very remarkable implication within numerous emotional and behavioral disorders in childhood and adolescence. In recent years there has been a significant increase in research on emotional regulation, however, the results are still divergent in terms of differences in emotional regulation in relation to age and gender. This study aimed to assess emotional regulation in adolescents in relation to their age and gender. Two (...) hundred and fifty-four adolescents from eight schools in the Valencian Community and aged between 9 and 16 years participated in the study. The adolescents completed the Cognitive Emotion Regulation Questionnaire and the FEEL-KJ questionnaire. We analyzed the differences in emotional regulation strategies and a latent emotional regulation variable in two age groups (9 to 12 years and 13 to 16 years) and by gender. The results suggested that children and pre-adolescents in the 9-12 year group obtained lower scores in the emotional regulation strategies than the 13-16 year group. Girls reported higher scores on the use of emotional regulation strategies when experiencing sadness, anxiety and anger than boys, and on the overall average of regulation according to these specific emotions. Age, but not gender, had a major effect on scores for the latent variable of emotion regulation. An interaction effect between age and gender was identified in the latent emotion regulation scores. Girls tended to have higher scores than boys when they were younger and lower scores than boys when they were older. These results could be relevant for designing prevention and intervention programs for adolescents and at different ages. (shrink)

In this article, I claim that the Antinomy of pure reason emerges as the result of synthetic activities that require succession. In this regard, I show that cosmological conflicts involve different kinds of representations: cosmological ideas, purely conceptual representations of the unconditioned and the product of non-temporal synthetic activities; and putative complete series of spatiotemporal conditions, which require temporal synthetic activities. As I show, purely conceptual representations cannot produce cosmological conflicts: The Antinomy requires the interaction of reason, understanding, and sensibility. (...) I also discuss the maxim and principle of pure reason, how they lead to the unconditioned, and how the cosmological syllogism produces the Antinomy. (shrink)

El artículo aborda las categorías de identidad y crisis desde la realidad histórica de América Latina -en sus expresiones culturales y políticas- para criticar desde allí el concepto de universalidad de la modernidad. Luego aborda el concepto de mundialización desde la sociedad postmoderna o postindustrial, para concluir -siguiendo a Zubiri, principalmente- con propuestas éticas desde la Unidad en la Diversidad, que nos permitiría como región integrarnos sin degradarnos en las profundas transformaciones del mundo contemporáneo.

El conocimiento histórico –entendido como un proceso metacognitivo de asimilación constructiva sobre el pasado para explicar fenómenos– comporta un análisis del impacto y la transcendencia de determinados acontecimientos y procesos históricos, en cuya comprensión y valoración influye el concepto de relevancia histórica. Desde esta perspectiva es necesario implementar propuestas de evaluación sólidas, vinculadas al desarrollo competencial. El objetivo de este estudio es diseñar una guía de caracterización de los instrumentos evaluativos –actividades y ejercicios– más utilizados por el profesorado de Historia, (...) con el fin de optimizar los procesos de evaluación de esta competencia mediante una serie de descriptores estructurales, competenciales y transferenciales. Estos indicadores de pertinencia pueden marcar el camino de aquellos docentes que deseen perfeccionar su manera de evaluar lo históricamente determinante. En conclusión, este innovador planteamiento supone un proceso de formación continua del profesorado que contribuye a la mejora de la calidad educativa. (shrink)

For one of the current scholars of Thomism, Serge T. Bonino, research on Thomas Aquinas’ philosophy of being has polarized into two tendencies, the axis of which is the Dominican Thomistic school. One of them is represented by the harsh criticisms that the French medievalist Étienne Gilson made of the positions of this school. The second, on the other hand, is characterized by a staunch defense of the theses of the main commentators of this school. During the 20th century, one (...) of Gilson’s students, the Canadian Lawrence Dewan, openly opposed Gilsonian Thomism on the basis of the traditional interpretation. Today, some of his students consider this Dewanian proposal as a “nouvelle métaphysique thomiste,” assuming that it is a movement that brings a genuine renewal. In this article we will show that this movement, although it claims to be a novelty, is nothing more than the revitalization of the formalist theses of the Dominican school, and therefore cannot be considered a valid interpretation of Thomas Aquinas.

RESUMEN Este artículo teje una relación entre el proceso de acumulación de tierras y el despojo en Colombia, para pensar, desde una perspectiva espacial, la relación que se construye con la guerra. El enclave teórico de este artículo sostiene que la colonialidad del poder es también una forma de disociación de la tierra que complejiza la experiencia de la servidumbre. A través de una lectura de pensadores como Marx, Harvey, Castro-Gómez y Mariátegui problematiza la experiencia del despojo de tierras en (...) Colombia y la economía del poder que de allí se desprende. ABSTRACT This paper exposes a relation between the accumulation and dispossession process of land in Colombia as a product of war, from a perspective of space. The theoretical frame of this paper assumes that coloniality of power is a complex form of dissociation of the land, one that transforms the experience of serfdom. Via reading thinkers like Marx, Harvey, Castro-Gómez, and Mariátegui, this paper problematizes the experiences of dispossession of land in Colombia and the economy of power that it engenders.

Los textos de este volumen ofrecen un enfoque menos frecuentado en torno a la cuestión postmoderna. Se trata de ir más allá del tópico general en las valoraciones de la postmodernidad, y conseguir así que ésta no consista, únicamente, en sus representaciones. Para ello, el volumen da cuenta de la dimensión estética del horizonte postmoderno, por un lado, y de su singular temporalidad, por otro. Desnuda ante el espejo, la postmodernidad descubre sus orígenes, lo mismo que sus carencias.

Nos proponemos abordar la tesis de la segunda antinomia. Primero, intentaremos demostrar que la tesis y su prueba sólo pueden versar sobre partes simples materiales de cuerpos extensos en el espacio, y no sobre sustancias simples inmateriales. En segundo lugar, intentaremos demostrar que en la tesis y su prueba intervienen una síntesis categorial y una síntesis empírica correspondientes a la categoría de cualidad, lo que conduce a afirmar que la prueba no procede por meros conceptos, sino que introduce cierta referencia (...) a la intuición. Dicha referencia será explicada a través de la síntesis empírica de realidad y confirmara que la tesis se refiere a partes simples corpóreas. (shrink)

La relación entre máxima lógica y principio sintético de la razón pura ocupa un lugar fundamental en la "Dialéctica trascendental". Esto se nota en la formulación de los problemas que la Dialéctica se propone abordar, pues hace una referencia explícita al pasaje de la máxima al principio mencionado ; sin embargo, Kant no explica cómo se haría tal pasaje. Aquí se propone una explicación de dicho pasaje a través de un estudio pormenorizado de la premisa mayor del silogismo cosmológico, donde (...) éste ocupa un lugar fundamental. se sostendrá que tal pasaje sólo es comprensible suponiendo una máxima lógica restringida que permita deducir legítimamente, para el caso de la lógica general, lo incondicionado dado a partir de lo condicionado dado. El principio trascendente será una pretendida extensión de esta máxima a las cosas en sí. The relationship between the logical maxim and the synthetic principle of pure reason plays an important role in the "Transcendental Dialectic". This is apparent by noting that the formulation of the problems treated in the Dialectic has an explicit reference to the transition from the maxim to the principle . Nevertheless, Kant doesn't explain how this transition is made. I intend to explain this transition through a detailed study of the major premise of the cosmological syllogism, where it has an important role. I claim that this passage is understandable only by assuming a restricted logical maxim that allows inferring legitimately the unconditioned given from the conditioned given. The transcendental principle will be an extension of this maxim to things in self. (shrink)

El artículo recorre la obra de Rodolfo Kusch posicionando sus principales propuestas en la construcción de tres enfoques convergentes en su filosofía. El primer enfoque está relacionado con la fenomenología y la cultura. El segundo enfoque se refiere a la influencia de la antropología y el cuestionamiento por el símbolo. El tercer enfoque despliega una aproximación filosófico-política. Estos enfoques permiten introducir tres “horizontes de pregunta” principalmente relacionados con el método, con lo popular y con lo indígena, que son expuestos como (...) asuntos centrales en toda su obra. Estos “horizontes de pregunta” buscan comprender los alcances de la filosofía de Kusch y su contribución al pensamiento filosófico americano. This paper analyses the work of Rodolfo Kusch remarking his main philosophical proposals through three correlated perspectives. The first perspective refers to phenomenology and culture. The second focuses on the influence of anthropology and the problem of symbols. The third posits a political-philosophical approximation. These perspectives operate interdependently as the background for Kusch’s philosophy and allow us to introduce three “questioning horizons” related to the method, the popular and the indigenous as the central issues of his philosophical work. Thus, these “questioning horizons” build a platform to understand Kusch’s philosophy and his contribution to the Latin American philosophy. (shrink)

Resumen. En México, la mercadotecnia promocional se ha erigido como la segunda más grande inversión demercadotecnia, principalmente debido a que las compañías tienden con más frecuencia a subcontratar laresponsabilidad de los aspectos operativos de la mercadotecnia. Las empresas contratantes exigen cada vezmás la garantía de seguridad y certidumbre en la prestación de los servicios, por lo que la calidad de éste seha convertido en un factor determinante en la elección de una agencia de promociones. El presentedocumento técnico busca compartir un (...) caso de estudio relacionado a una empresa de promoción de ventasque enfrenta una alta tasa de deserción de clientes con su consecuente contracción en las ventas, pero quecontradictoriamente está inmersa en un mercado que tiene un crecimiento sostenido del 15 por ciento en losúltimos años. El problema fue abordado desde la perspectiva de la calidad en el servicio y la satisfacción delcliente a través de la aplicación de encuestas Servqual a algunos clientes de la compañía. Dichas encuestaspermitieron: identificar las dimensiones de calidad relevantes en el servicio, detectar las áreas de oportunidadentre el servicio esperado y el servicio real, y la elaboración de un plan de acción que posteriormente fuesistematizado e implementado. Los resultados muestran que la implementación del sistema de calidad redujola deserción de los clientes; además, se descubrió que las dimensiones de calidad del Servqual afectan enproporciones diferentes a la satisfacción del cliente.Palabras Claves. Calidad en el servicio, deserción de clientes, mercadotecnia promocional, promoción deventas, QFD, satisfacción del cliente, Servqual, sistema de calidad.. In Mexico, the promotional marketing has emerged as the second largest marketing investment,mainly because companies tend to outsource most often the operational aspects of marketing. Thosecompanies are increasingly demanding security and certainty in the delivery of services. As a consequence,service quality has become a determining factor in the election of a sales promotion agency. This technicalpaperwork shares a case study related to a sales promotion company facing high customer defection rate withits consequent contraction in sales, but ironically immersed in a market that has a sustained growth of 15 per cent in recent years. Approach of the problem was from quality service and customer satisfaction perspectivethrough the use of Servqual surveys applied to some customers. These surveys allowed: to identify relevantdimensions of quality service, to identify opportunities between the expected service and the actual service,and the development of an action plan which was later systematized and implemented. Results show that theimplementation of the quality system reduced customer desertion. Also, found that the quality dimensions of SERVQUAL affect customer satisfaction in different ways.Keywords.

Human suffering is a complex and multidimensional phenomenon of special interest for psychotherapy. Psychotherapists deploy various epistemological processes that act as mediators when understanding the human suffering afflicts their clients. However, these issues are scarcely considered by psychotherapists and are rarely addressed in specialized literature. In this sense, and seeking to respond to this problem, this theoretical article aims to analyze the epistemic mediators of the psychotherapist that affect the process of knowledge of the client's human suffering. Three mediators will (...) be analyzed: 1) the general epistemic framework (psychotherapeutic approach of ascription), 2) the specific epistemic framework (personal epistemology of the therapist), and 3) the hegemonic epistemology (positivism) together with its role in the psychopathologization of life, the objectification of suffering and mental health. It is concluded that human suffering is a constant construction phenomenon dependent on the psychotherapist's epistemic mediators, impacting various areas of praxis. Finally, the limitations, implications, and contributions of the issues discussed in the discipline are presented. (shrink)

Science is the practice that provides the most epistemically warranted claims that can be made, and involves the possibility that explanatory theories will eventually be replaced by better ones. In the case of Psychology, the process of formulating theories through the scientific method has been difficult and has generated concern among scientific psychologists. Thus, in 1978 Meehl published a seminal text about the weakness of psychological theories, which has had a great influence to this day, with different authors describing a (...) theoretical crisis in Psychology. This manuscript reviews the current panorama of the situation, characterizing the crisis, the associated factors and the proposals to solve it. In relation to the factors associated with the crisis, the youth of Psychology, the emphasis on data, problems in the definitions of constructs and their measurement, and difficulties in determining causality in Psychology are highlighted. With respect to the solutions, the proposals for including training in theory construction in the study plans, the integration of interdisciplinary skills, the theory formation cycle, and the formation of theories are reviewed. It is concluded about the need to include theoretical training within university curricula, as well as the possibility that Theoretical Psychology is a viable specialization for psychologists.

In Artificial Intelligence, Artificial Neural Networks are very accurate models in tasks such as classification and regression in the study of natural phenomena, but they are considered “black boxes” because they do not allow direct explanation of what they address. This paper reviews the possibility of scientific explanation from these models and concludes that other efforts are required to understand their inner workings. This poses challenges to access scientific explanation through their use, since the nature of Artificial Neural Networks makes (...) it difficult at first instance the scientific understanding that can be extracted from them.

Este artículo tiene como objetivo fundamental presentar, esquemáticamente, las perspectivas teóricas, las estrategias metodológicas y los resultados de la investigación titulada “Genealogía de las prácticas confesionales en la Reforma Protestante: un análisis histórico de las relaciones de poder”. En la primera parte, se muestra el marco teórico general mediante el cual nos aproximamos a la relación entre el lenguaje y la política. Esto tiene como fin caracterizar el problema con el que la investigación se comprometió y la forma en la (...) que se trató de resolver. De igual modo, en la segunda parte se indica la confesión protestante. Allí se hace énfasis en la problematización de las prácticas sociales asociadas al ascetismo puritano en términos que involucran los conceptos de ejercicio de sí, subjetividad y pliegue. Finalmente, trae a colación el tema de las diferenciaciones políticas en la Colonia para mostrar cómo se puede proceder en el intento de aplicar las formulaciones teóricas venidas de los análisis previos de la investigación a un problema específico de la historia colombiana. Al final, se compilan las conclusiones de cada uno de los estudios. (shrink)

El texto presenta una visión detallada sobre la importancia y operación del Observatorio de la Red Iberoamericana de Bioética (ORIBI), argumentando la relevancia de la bioética en la contemporaneidad. La bioética, definida como la ética aplicada a la vida, ha expandido su influencia más allá de la medicina para abarcar áreas como el medio ambiente, derechos humanos y lucha contra la pobreza, destacando el enfoque interdisciplinario esencial para abordar dilemas éticos complejos. El ORIBI, desarrollado por el Centro Anáhuac de Desarrollo (...) Estratégico en Bioética (CADEBI), busca consolidar algunos esfuerzos dispersos en Iberoamérica, fomentando la colaboración regional en investigación, formación y gestión de la bioética. Se destaca la necesidad de trabajo colaborativo entre observatorios existentes, aprovechando recursos y conocimientos para promover el bienestar social. El ORIBI planea su acción en torno al monitoreo continuo, análisis de actividades y red de vinculación, apoyándose en herramientas como el Atlas Iberoamericano de Bioética y una serie de indicadores de seguimiento. Este enfoque estratégico y flexible permite adaptar la operación del observatorio a desafíos emergentes. (shrink)

In this paper we intend to offer a first approach to the incorporation of certain formal tools in the elucidation of some issues discussed in epistemological contexts. The aim is not to offer an exhaustive resolution of these problems but merely to point out the usefulness of modal semantics when applied to different fields. Here we will show how a series of skeptical arguments eventually involve a modal structure, which we will try to generalise into a useful scheme.

The following study shows the main qualitative results obtained by means of a two follow up study with a group of telephone interpreters who previously participated in an ad hoc emotional regulation program designed according to their specific needs.The study aimed to evaluate the impact of the intervention program in the long term.The results demonstrated the positive effect of the program on the interpreters’ lives and on their emotional management.The need of verifying the effect of this kind of programs in (...) order to totally measure their impact through the time is discussed.

After the criticism that Martin Heide-gger made of Western metaphysics some authors like Gilson or Fabro, among others, wanted to enter into confrontation giving them the oppor-tunity to study in depth most important theses of authors like Thomas Aquinas and his esse philo-sophy. Gilson’s theses had an important impact on the world of Thomism, but Lawrence Dewan, also a Thomist, wanted to defend against Gilson the traditional interpretation of Cayetano and Capreolo, which until now had been regarded as the most (...) celebrated commentators of Thomas. This article investigates a specific point of this confrontation: the causation of esse. El legado de Martin Heidegger con su crítica a la metafísica occidental ha suscitado numerosos estudios en torno a la perenne cuestión acerca del ser, la metafísica y el fundamento mismo de la filosofía. Étienne Gilson, entre otros autores, fue un medievalista que tomó el pulso al pensador alemán para demostrar que Tomás de Aquino no esencializó el ser, como aquél pretendía. Sin embargo, junto con el Francés, en torno a la filosofía del ser tomista surgieron otros estudiosos que quisieron confrontar el tomismo gilsoniano con lo que entendían era un modo más adecuado de entender el verdadero tomismo. Uno de los puntos más interesantes sobre esta confrontación es, sin duda, el papel del esse tomista en la comprensión de la causalidad, entrando aquí en juego, a posteriori, interesantes cuestión en torno a la relación entre el pensamiento tomista y el aristotélico.

RESUMEN El objetivo de este artículo es proponer una reinterpretación del concepto de comunidad a la luz de las transformaciones tecnológicas y de las formas de comunicación recientes, las cuales ponen la idea de lo social no como precepto teórico, sino como elemento a descubrir en los diferentes estudios planteados. Se busca una transversalización teórica de los tres autores, tomando elementos esenciales de sus obras para proponer una nueva clave interpretativa que permita tomar el concepto de comunidad no como un (...) presupuesto teórico, sino como un producto inmanente, resultado de las conexiones cotidianas que se realizan entre los sujetos de manera espontánea en el campo de lo social. ABSTRACT Taking as a starting point the objective of this article is the reinterpretation of the concept, forced by the technological and communication transformations that place the ideas of social and community, not as theoretical precepts, but as elements to discover on the studies proposed. A theoretical transversalization of the three authors will be sought, taking essential elements from their works to propose a new interpretative key that allows us to take the concept of community, not as a theoretical presupposition, but as an immanent product resulting from the daily connections made between the subjects, spontaneously, on the social field.
