The introduction of a new analytical method, due fundamentally to François Viète and René Descartes and the later dissemination of their works, resulted in a profound change in the way of thinking and doing mathematics. This change, known as process of algebrization, occurred during the seventeenth and early eighteenth centuries and led to a great transformation in mathematics. Among many other consequences, this process gave rise to the treatment of the results in the classic treatises with the new analytical method, (...) which allowed new visions of such treatises and the obtaining of new results. Among those treatises is the Arithmetic of Diophantus of Alexandria which was written, using the new algebraic language, by the French mathematician Jacques Ozanam, who in addition to profusely increasing the original problems of Diophantus, solved them in a general way, thus obtaining many geometric consequences. The work is handwritten, it has never been published, it has been lost for almost 300 years, and the known references show its importance. We will show that Ozanam’s manuscript was quoted as an important work on several occasions by others mathematicians of the time, among whom G. W. Leibniz stands out. Once the manuscript has been located, our aim in this article is to show and analyze this work of Ozanam, its content, its notation and its structure and how, through the new algebraic method, he not only solved and expanded the questions proposed by Diophantus, but also introduced a connection between the algebraic solutions and what he called geometric determinations by obtaining loci from the solutions.

El ser humano inventó las técnicas que hicieron evolucionar al hombre como género. La historia de todas las formas culturales y civilizatorias de nuestra especie, Homo sapiens, puede explicarse al ritmo de las revoluciones tecno-energéticas, que han marcado las épocas de auge, abocadas ineluctablemente a una ulterior crisis y decadencia, salvo que una renovación o innovación tecnológica permita la superación. La utopía moderna del progreso mediante el dominio industrial y despótico sobre la naturaleza ya se ha realizado lo suficiente, como (...) para hacer ver que el sistema tecnológico hiperindustrial dominante, con la política económica que conlleva, es causa de la actual crisis mundial de la civilización humana. Tal sistema está en entredicho, por su carácter no adaptativo para la especie: su mundialización resulta materialmente inviable, dadas las consecuencias catastróficas que produce para la biosfera y vistas las desigualdades explosivas que fabrica entre las poblaciones humanas y dentro de cada una de ellas. La pregunta es si cabe la posibilidad de humanizar y ecologizar la tecnología, lo que exige una «política del hombre», único camino para prevenir la autodestrucción de la humanidad. (shrink)

Objective: This study aimed to compare the effects of two intervention programs, high-intensity interval training and moderate-intensity training, on anxiety, depression, stress, and resilience during the confinement caused by the coronavirus disease 2019 in healthy adults.Methods: A total of 67 adults who participated were randomly assigned to two groups: HIIT and MIT groups. The MIT group had to perform a home-based intervention based on aerobic exercises, whereas the HIIT group had to perform a home-based intervention based on HIIT exercises. The (...) two groups had to complete the same physical exercise volume, 40 min per session during the confinement period. Depression, anxiety, stress, and resilience were assessed before and after the intervention.Results: Results showed that HIIT and MIT significantly reduced the stress, anxiety, and depression as well as increase the resilience. Moreover, the improvements obtained in the HIIT group seem to be greater than those of the MIT group in depression.Conclusions: HIIT and MIT decreased anxiety, stress, and depression as well as increased resilience during the COVID-19 confinement. In addition, the HIIT intervention seemed to be more beneficial to reduce depression than the MIT intervention. (shrink)

Background The COVID-19 pandemic has influenced the approach to the health-disease system, raising the question about the principles of bioethics present in physician–patient relations. The principles while widely accepted may not be sufficient for a comprehensive ethical analysis. Therefore, the aim of this study was to explore the perception of these principles and the physician–patient relationship during a hospital stay through a qualitative approach. Method Sixteen semi-structured interviews took place to know the patients’ perception during their 2020 hospitalization for COVID-19. (...) The data was analyzed through the constant comparison method, creating categories and comparing them. In the end, seven categories were established and were grouped in three: bioethical principles (dignity, charity, vulnerability, autonomy), doctor-patient relationship (participant commitment, informed consent, health staff-patient relationship) and the experience of the disease (illness, the role of the family). Results The research found that most patients described a positive experience, with the feeling of having been well cared for with no sense of discrimination or injustice done. The majority also reported that their autonomy was respected in the treatment decisions. The evaluation of these attitudes is an area of opportunity, especially when the patients' vulnerability is at risk. Conclusions The ethics of virtue offers a better reflection of how human beings manifest themselves by emphasizing the development of virtuous character and behaviors that allow them to realize their values in life.

I argue that the opening line of the _Phaedrus_ proleptically encapsulates the major themes of the dialogue and that paying attention to the opening line enables us to strengthen the identification of psychagogy as the key unifying thread of the whole dialogue. In particular, I argue that the opening line foreshadows the quarrel between Lysias and Socrates over the practical guidance of Phaedrus’ soul; the prominence of friendship in the philosophical form of life; the pertinence of Socrates’ one-on-one, custom-built speeches, (...) vis-à-vis the later conceptualization of rhetoric; the definition of the soul as a source of never-ending movement; as well as the origin (_arché_) and destiny (_télos_) of human souls, following the lines of the Palinode.

Since the 1980s, there has been a significant increase in the number of studies concerning Andalusian rural settlements linked to irrigated agriculture, both related to large suburban green belts and to small hydraulic systems. In the vast areas where water is scarce, the settlement apparently would have been concentrated in cities and fortified towns, leaving without population most of the dry lands between them. However, thanks to the intensive survey of one of these regions, La Mancha’s Southeastern area, we are (...) recording a dense rural settlement corresponding to a pattern unknown until now. It consists basically of small villages in plain, devoid of community defense elements, which must have been inhabited by humble peasants, judging by the modesty of the architecture and domestic goods. Surely they make use of the scanty natural resources, which have traditionally oriented the economy of the region towards livestock and rainfed agriculture. In particular, the studied settlement would be related to the demand of wool for the export oriented textile production of the region, within the framework of the commercial expansion of that period. Apparently, most of those villages could have appeared in the eleventh century, disappearing in the middle of the thirteenth century because of the Christian conquest. Their existence would be associated with a general context of population growth that pushed the competition between urban elites and peasants pursuing the privileged agricultural areas, as well as the colonization of less favorable production areas.

Processing data streams arriving at high speed requires the development of models that can provide fast and accurate predictions. Although deep neural networks are the state-of-the-art for many machine learning tasks, their performance in real-time data streaming scenarios is a research area that has not yet been fully addressed. Nevertheless, much effort has been put into the adaption of complex deep learning (DL) models to streaming tasks by reducing the processing time. The design of the asynchronous dual-pipeline DL framework allows (...) making predictions of incoming instances and updating the model simultaneously, using two separate layers. The aim of this work is to assess the performance of different types of DL architectures for data streaming classification using this framework. We evaluate models such as multi-layer perceptrons, recurrent, convolutional and temporal convolutional neural networks over several time series datasets that are simulated as streams at different speeds. In addition, we evaluate how the different architectures react to concept drifts typically found in evolving data streams. The obtained results indicate that convolutional architectures achieve a higher performance in terms of accuracy and efficiency, but are also the most sensitive to concept drifts. (shrink)

Este artículo pretende establecer los nexos y asociaciones de los conceptos fundamentales que sustentan la obra filosófica, pero sobre todo la critica literaria de Rafael Gutiérrez Girardot. Hegel y Schlegel aparecen como pilares que fundamentan sus interpretaciones criticas y sobre los cuales se abre el horizonte de América Latina; a través de autores como Jorge Luis Borges, Alfonso Reyes y César Vallejo.

ABSTRACTCarnap famously argued that there are two kinds of questions and claims concerning the existence or reality of entities: internal and external ones. We focus on Carnapian external ontological claims of the form: ‘Xs really exist’, where ‘X’ stands for some traditional metaphysical category, such as ‘substance’, ‘fact’ or ‘structure’. While Carnap considered them as meaningless, we consider them as faultlessly meaningful. However, in line with an expressivist guise, we do not claim that they have the meaning they have in (...) virtue of representing a certain range of entities in the world or describing pieces of reality. Quite the contrary, we maintain that they are meaningful because they perform a function that is fundamentally expressive, that is, a non-descriptive function. In particular, they may imply a distinctive type of metalinguistic expressive function. Moreover, we avoid accuses of mentalism insofar as we explain the meaning of external ontological claims in terms of the practical commitments to the adoption of certain linguistic forms they express, rather than as expressing some kind of mental state.

Entre los documentos del exjesuita peruano Juan Pablo Viscardo y Guzmán que el venezolano Francisco Miranda recibió del plenipotenciario norteamericano en Inglaterra, Rufus King, se encontraba la "Carta dirigida a los españoles americanos". Este pieza documental, considerada "la primera proclama de la independencia" hispanoamericana, había sido escrita originalmente en francés hacia 1792 como testimonio de protesta de la situación de vejación y sometimiento que tenía España a sus colonias americanas, para ser presentada ante las autoridades inglesas. El entusiasmo que despertó (...) la "Carta" del fallecido jesuita en el temible e infatigable conspirador Miranda, fue inequívoca, al punto que no sólo se dispuso a traducirla y publicarla (Londres, 1801), sino la presentó, en su frustrada expedición de Coro en agosto de 1806, como portaestandarte de la cruzada libertadora.

Este artículo discute y analiza la formación del carácter crítico e intelectual en Rafael Gutiérrez Girardot. A partir de fuentes diversas y, en parte, inexploradas, se reconstruye el proceso de formación y ejercicio de su actividad crítica entre 1950 y 1965. Se tienen en cuenta tanto las relaciones con otros intelectuales como la influencia de los diversos contextos en los cuales se dieron dichas relaciones. Así, su participación en Cuadernos Hispanoamericanos, su correspondencia con Alfonso Reyes y con Nils Hedberg, su (...) actividad diplomática, su trabajo editorial y de traducción y, finalmente, su práctica docente, se estudian con objeto de tener un marco comprensivo. La obra crítica de Gutiérrez Girardot dista de estar comprendida y, de hecho, se precisa todavía de un exhaustivo trabajo de reconstrucción y análisis. This paper discusses and analyses the critical and intellectual nature of the work of Rafael Gutiérrez Girardot. It reproduces the process of construction and exercise of his critical activity (1950-1965), based on different sources some of them not yet very studied. The paper takes into account his relationships with other intellectuals and the influence of its different contexts. Thus, in order to get a comprehensive framework, it studies his participation in Cuadernos Hispanoamericanos, his correspondence with Alfonso Reyes and Nils Hedberg, his diplomatic activity, his work as editor and translator and finally his teaching experience. The critical work of Gutiérrez Girardot is far from being completely interpreted and this makes necessary an exhaustive work of reconstruction and analysis. (shrink)

El presente artículo aborda la profunda relación de Nietzsche con el lenguaje desde la perspectiva de la filosofía, de la filología y de la poesía. Son reflexiones que remiten al interés del filósofo por la retórica, del filólogo por el estilo, y del poeta que hace uso del lenguaje lírico. Se analizarán cuestiones básicas en la escritura de Nietzsche como la musicalidad, el ritmo, el tono, la metáfora y el carácter dialógico de sus textos.

Este artículo estudia la hipotética penetración del islamismo –vertiente degradada del Islam- en algunos sectores de la extrema izquierda en Latinoamérica y reflexiona sobre su habilidad para desarrollar tanto una teoría como una práctica islamizadas de la revolución. El objetivo de esto es indagar en un aspecto inusual de la seguridad, el factor ideológico, habitualmente soslayado por preferirse los elementos estratégicos y tácticos. Para ello primero se investigan someramente algunos cambios del terrorismo ligados al islamismo en Latinoamérica. Después se analiza (...) la doctrina mediante la que el islamismo puede conectar con la extrema izquierda mediante los conceptos de revolución, guerra revolucionaria, guerra asimétrica y yihad. Finalmente están las conclusiones del artículo. (shrink)

Este artigo compara e contrasta dois conceitos filosóficos provenientes de distintas linhagens de pensamento: de um lado, o _clinamen _de Lucrécio; do outro, o _conatus _de Espinosa. O que fomentou minha pesquisa foi uma conjugação dessas noções tal como proposto por Deleuze no apêndice de seu _Logique du sens_. Nesse sentido, a primeira seção está orientada tendo em vista uma elucidação da filosofia de Lucrécio — consequentemente, também a de Epicuro — e, especificamente, uma interpretação do desvio dos átomos ou (...) _clinamen_ em combinação com o tópico da liberdade. A segunda seção se dedica a clarificar a metafísica de Espinosa e a acomodação do tema da liberdade dentro de seu robusto enquadramento necessitário, entrelaçado com o motivo do _conatus _ou esforço de auto-preservação. Contra a leiture de Deleuze, entretanto, argumentarei que _clinamen _e _conatus _pertencem à sistemas metafísicos que são praticamente incompatíveis e que corroboram um entendimento diferente sobre liberdade e necessidade.

Based on the results obtained from primary education students—fifth and sixth graders—the aim of this work is to check the appropriate self-perceived behaviors during and at the end of the game. The study population was made up of 698 students from fifth and sixth grade in the Autonomous Region of Castilla–La Mancha (Spain). Data were collected through a questionnaire (scale) on the social skills of primary school students linked to the adequate skills when losing, the adequate skills when winning, and (...) the adequate skills during the game. Study results revealed that analyzed behaviors vary, depending on the moment of the game, being it more frequently during the development of the game than when losing or winning. (shrink)

Introducción: Los cambios biológicos, sicológicos, económicos y sociales que se observan durante el envejecimiento conllevan a pensar que en los ancianos existe una serie de factores que favorecen la aparición de una depresión. Objetivo: evaluar la efectividad de una intervención sicológica para disminuir la depresión en adultos mayores de la Casa de abuelos "Dr. Diego Tamayo Figueredo", de Puerto Padre, en el período de noviembre de 2013 - mayo de 2014. Material y métodos: se realizó un estudio de intervención sicológica (...) en una muestra de 12 adultos mayores de la casa de abuelos. Se aplicó un programa de intervención sicológica, así como la Escala de Depresión Geriátrica para realizar la valoración antes y después de la intervención. Se empleó el modelo Cognitivo- Conductual de Beck. Los datos fueron tratados según la estadística descriptiva. Resultados: el porciento más elevado de pacientes correspondió al grupo de ancianos con edades entre los 60 y 90 años de edad. Respecto al sexo, el más frecuente es el masculino. El asma bronquial, la hipertensión arterial y la diabetes Mellitus representaron el mayor porciento de antecedentes patológicos personales. Conclusión: la intervención sicológica resultó efectiva pues se logró disminuir a leve los niveles iniciales de depresión establecida y los considerados con leve a no depresión, por lo tanto se afirma que con su aplicación fue modificado el estado emocional de los adultos mayores que se implicaron en la muestra. Introduction: Biological, psychological, financial and social changes observed during aging lead to think that there is a series of factors that favor the appearance of depression in senior citizens. Objective: Assessing the effectiveness of a psychological intervention in order to reduce depression in senior citizens from "Dr. Diego Tamayo Figueredo" Senior Citizens' House, Puerto Padre, from November 2013 to May 2014. Material and methods: A psychological intervention study was conducted on a sample of 12 senior citizens from the house. A psychological intervention program as well as the Geriatrics Depression Scale were applied before and after the intervention in order to make the assessment. The Beck's cognitive-behavior model was used. Data was processed according to descriptive statistics. Results: The highest percentage of patients corresponded to a group of seniors between 60 and 90 years of age. Regarding sex, males are more common. Bronchial asthma, arterial hypertension and diabetes mellitus represented the highest percentage of personal pathological history. Conclusion: The psychological intervention proved to be effective since initial established depression levels were reduced to minor and those considered as minor were reduced to no depression ; therefore, it is stated that its application modified the state of mind of the senior citizens involved in the sample.

La pandemia mundial del coronavirus ha supuesto una de las mayores conmociones de nuestra historia reciente y, como tal, parece obligarnos a repensar nuestros modos de organización y formas de vida e, incluso, como se propone aquí, a plantearnos cómo podríamos habitar el colapso. En este escenario incierto y desconocido, la filosofía, con sus múltiples enfoques y subdisciplinas, se presenta como un lugar privilegiado para analizar las vertiginosas transformaciones que han dado lugar a esta “nueva normalidad”. El presente monográfico aglutina (...) una serie de contribuciones realizadas por distintos investigadores e investigadoras de la Universidad de Oviedo, que han tratado de abordar la crisis sanitaria global desde diversas perspectivas filosóficas y humanísticas. Entre los temas que se estudian en estas páginas, figuran los relativos a la gestión de la pandemia y la comunicación científica sobre la misma, las relaciones entre pobreza, salud mental y suicidio o el alcance de la revalorización del mundo rural. También se utilizan las herramientas del análisis biopolítico para examinar la gestión de los cuerpos durante la pandemia a partir de tres ejes distintos: el tratamiento de los enfermos, los nuevos dispositivos de control y la gestión de la pandemia en las instituciones de encierro. Además, varios de los capítulos se ocupan explícitamente de un tema inherente a la mayoría de las reflexiones que componen este volumen: a saber, el de la necesidad de un cuestionamiento profundo de la sociedad occidental contemporánea y la insostenibilidad de su forma de vida.
