El neopragmatismo ha renovado la vieja cuestión del relativismo epistemológico pero enfocándolo, ahora, desde el horizonte del lenguaje. En particular el profesor Richard Rorty ha avanzado algunas tesis que han conmovido al mundo académico, llevando la disuasión hacia un asunto pertinente: ¿Qué función debe cumplir la filosofía? ¿Verdad o solidaridad? ¿Universalismo o contextualismo? Rorty se muestra partidario, a partir de la crítica a la verdad como espejo de la naturaleza, a retomar el diálogo socrático en el que todas las voces (...) puedan tener cabida bajo supuestos de responsabilidad y simpatía en la búsqueda de acuerdos siempre renovables. En definitiva más ética y responsabilidad en la finitud humana, que verdad en la trascendencia histórica. (shrink)

El autor interpreta el pragmatismo defendido por R. Rorty como una variante más del cambio cultural denominado "Postmodernidad ", e identifica y comenta algunas afirmaciones rortianas sobre el sentido de la filosofia y el pensamiento crítico que le permitan encarar los temores expresados por J. Searle sobre el posible irracionalismo ofrecido por los posmodernos en el campo de la educación. A fin de establecer un marco conceptual lo suficientemente amplio para desarrollar su tesis, el autor confronta dos de las múltiples (...) distinciones ofrecidas sobre el sentido de la "postmodernidad" para criticar la epistemología como núcleo de las tareas de la modernidad occidental. Establecido dicho marco se da paso a algunas de las tesis de Rorty sobre el sentido que toman en su propuesta los conceptos de filosofia, razón y educación. Desde este punto de vista, la educación se convierte en una genuina actividad ética y no en una nueva destreza metodológica propia de la educación liberal ilustrada tal como la defiende Searle. Otra tesis complementaria del autor es que la posmodernidad no es el reino del relativismo ni la sinrazón. (shrink)

El debate teórico sobre las reacciones entre la concepción neoliberal y la filosofía apenas si ha llamado la atención de la sociedad contemporánea. El interés se ha centrado básicamente en el aspecto económico social. En este artículo se da cuenta, someramente, de tres dominios conceptuales que entran en el debate: economía política y teología. Los autores considerados son Adam Smith, John Rawls y Michel Novack.

Desde el punto de vista de Frege, la expresión "teoría formal de la aritmética" puede designar dos concepciones muy diferentes, de las cuales él defendió una con tanto ardor como combatió a la otra. La segunda es la concepción formalista vulgar, según la cual, en aritmética "los signos son vacíos y constituyen ellos mismos los números. La primera es la que atribuye a la aritmética un carácter "formal", en el sentido de "puramente lógico" que la distingue radicalmente de la geometría (...) y la aproxima a la lógica propiamente dicha.

La Iglesia de América Latina y el Caribe recibe del Concilio Vaticano II una fuerza crítica y profética, que se evidencia en la Segunda Conferencia del Episcopado, reunida en Medellín, en 1968. A partir de la originalidad propia de nuestra amerindia, este Concilio se asume, integra y traduce para vivir su inspiración y derroteros fundamentales. La iglesia de la que somos testigos hoy, 50 años después de Medellín, se ha entretejido desde allí. Prueba fehaciente de ello, en este continente, son (...) aquellas comunidades que testimonian a una iglesia liberadora y misericordiosa, nazarena y samaritana, una iglesia que es pueblo de Dios y de los pobres, una iglesia comunitaria de comunidades y, siempre, en salida. Comunidades que han trabajado en aras de la paz, la justicia y la dignidad de todos; en una búsqueda y respuesta real de organización, de lucha ante la opresión y explotación de cualquier orden.

The progress of Mathematics during the nineteenth century was characterised both by an enormous acquisition of new knowledge and by the attempts to introduce rigour in reasoning patterns and mathematical writing. Cauchy’s presentation of Mathematical Analysis was not immediately accepted, and many writers, though aware of that new style, did not use it in their own mathematical production. This paper is devoted to an episode of this sort that took place in Spain during the first half of the century: It (...) deals with the presentation of a method for numerically solving algebraic equations by José Mariano Vallejo, a late Spanish follower of the Enlightenment ideas, politician, writer, and mathematician who published it in the fourth (1840) edition of his book Compendio de Matemáticas Puras y Mistas, claiming to have discovered it on his own. Vallejo’s main achievement was to write down the whole procedure in a very careful way taking into account the different types of roots, although he paid little attention to questions such as convergence checks and the fulfilment of the hypotheses of Rolle’s Theorem. For sure this lack of mathematical care prevented Vallejo to occupy a place among the forerunners of Computational Algebra. (shrink)

The Coronavirus Disease 2019 pandemic, now a global health crisis, has surprised health authorities around the world. Recent studies suggest that the measures taken to curb the spread of the COVID-19 outbreak have generated issues throughout the population. Thus, it is necessary to establish and identify the possible risk factors related to the psychosocial and psychophysiological strain during the COVID-19 outbreak. The present extensive literature review assesses the social, psychological, and physiological consequences of COVID-19, reviewing the impact of quarantine measures, (...) isolation, vast human loss, social and financial consequences in the family’s economies, and its impact on the psychological health of the population. We also discussed the effect of psychophysiological factors, considering the impact of physical inactivity and modifications in nutritional habits, at psychological and physiological levels. The present review includes an actualized to date bibliography, articles for which were methodologically analyzed to verify they met the standards of quality and scientific accuracy. Authors understand the pandemic as a multifactorial event for which only a profound and extensive analysis would lead to better compression and efficient intervention in the near future. (shrink)

La idea de convergencia es una de las nociones más difundidas en el lenguaje tecnocientífico actual. Sin olvidar el éxito que está teniendo en el diseño de la política europea, no cabe duda de que es un concepto clave en la financiación de las investigaciones integradas en el marco de lo que se ha denominado las NBCI (nano-bio-cogno-info-tecnologías). Con ello, pretendemos analizar hasta qué punto se está difundiendo algún sesgo axiológico a través de esta noción. Algo que cobra especial interés (...) si tenemos en cuenta la acogida que está teniendo en los recientes estudios sobre el nuevo modo de producción del conocimiento tecnocientífico (Gibbons, Nowotny, Funtowicz…) y el giro económico que estos han experimentado en los últimos años.

Despite the importance of network analysis in biological practice, dominant models of scientific explanation do not account satisfactorily for how this family of explanations gain their explanatory power in every specific application. This insufficiency is particularly salient in the study of the ecology of the microbiome. Drawing on Coyte et al. (2015) study of the ecology of the microbiome, Deulofeu et al. (2021) argue that these explanations are neither mechanistic, nor purely mathematical, yet they are substantially empirical. Building on their (...) criticisms, in the present work we make a step further elucidating this kind of explanations with a general analytical framework according to which scientific explanations are ampliative, specialized embeddings (ASE), which has recently been successfully applied to other biological subfields. We use ASE to reconstruct in detail the Coyte et al.’s case study and on its basis, we claim that network explanations of the ecology of the microbiome, and other similar explanations in ecology, gain their epistemological force in virtue of their capacity to embed biological phenomena in non-accidental generalizations that are simultaneously ampliative and specialized.

It can be stated that self-regulated learning (SRL) brings broad benefits to the process of students' learning and studying. However, research has yet to be undertaken in relation to one of its components, namely self-regulation of motivation and affectivity. The main objectives of this study are to examine the use of self-motivation strategies that involve classmates and to obtain models on the influence of academic goals and self-efficacy on such self-motivation strategies. To this end, was conducted a study using two (...) different samples of students in the compulsory secondary education or baccalaureate stages in Spain (N = 613 and N = 910). The results obtained indicate that, with regard to gender, differences only exist in the use of the strategy of deception (t = 5.450, p <.001, d =.364). That the two pairs of strategies positively and significantly correlated with one another (r =.239, p <.01 and r =.355, p <.01). That only the strategy of annulation of others correlates with a more adaptive type of motivation. Thus, the group of students that reported the greatest level in its use also did so in relation to task and ego self-enhancing goals, to self-efficacy, and being negatively associated with the goal of work avoidance. Finally, were offered models on relationships between academic goals, self-efficacy and enhancement and annulation strategies (χ² (8) = 5.204, p =.736) and deception and annulation strategies (χ² (4) = 3.228, p =.520).

I. INTRODUCTIONThe Parshall Flume, which was invented in 1920 by R. Parshall, is mostly used in wastewater and crop supply. Utilizing equations, Parshall established dimensions that fit the design, one of the advantages is the conversion of position energy to velocity energy since in other measurement structures there are minimum energy losses in this one it does not allow sedimentation. The structuring of the project is adhered to by different models that define its behavior and limit its use. This is (...) the case of an approach length of the channel entrance, which is nothing more than a primary distance for the action of the flow within the channel. Throughout history, some studies were conducted in an attempt to establish an approximate and realistic value of the length at the time of measurements, but the theories put forward were lost. Some people link this length with the narrowing of the gorge, and others suggest flow conditions before entering the flume. For the development of the project established with its respective objectives, the respective structuring was carried out: For the measurement, the points already established in the field will be taken with the help of a total station, GPS, to verify the respective measurements of the Parshall flume. For the calculations and the design, the points will be introduced in the civil 3D to be able to verify if the points taken are the correct ones and what distances they have between them, through this, we can apply different methods to be able to verify the design that has this Parshall flume. For the evaluation and layout of the gutter, if it is the case, we will carry out a layout in plan with the data already calculated in the office and we will evaluate the situation in which it is so that we can apply a possible solution so that a defect does not occur. In this report, we focus on the design and redesign of a hydraulic irrigation channel where we find a Parshall section, which has the function of measuring the flow found in that section. The measurements found in the field can be verified in the office using formulas and software to verify if the data are correct, if so we can say that it is well designed, otherwise we will look for a possible solution by doing a field study.

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.

Background. The study of entrepreneurial activity has undergone intense development in recent decades. Traditionally this topic has been addressed from three approaches: economic, sociological and psychological. In the study of enterprising personality, two fundamental perspectives stand out: the use of general personality traits, like the Big Five, and the use of more specific traits related to entrepreneurial spirit, such as self-efficacy, autonomy, innovation, optimism, and others. The objective of this study is to provide validity evidence for a new instrument for (...) measuring eight specific dimensions of entrepreneurial personality (BEPE). Method. The sample was composed of 1,170 adults from the general population (59.9% women). The average age was 42.34 years with a standard deviation of 12.96. Of the sample, 13% were self-employed. Internal factorial structure and reliability of BEPE were examined. The relationships with other variables and the discriminative capacity of the BEPE between different groups of workers were analyzed. Results. First order factor analyses show the essential unidimensionality of each of the eight proposed sub-scales, with factorial weights ranging between 0.341 and 0.825. A second-order factor analysis was carried out, obtaining a general dimension of entrepreneurial personality. With regards to reliability, the eight BEPE sub-scales gave high alpha coefficient values, between 0.825 and 0.899, as did the total battery (0.97). BEPE sub-scales show a high canonical correlation with the Big Five personality factors (.795), and with the sub-scales of the Measure of Entrepreneurial Talents and Abilities questionnaire (.815). Conclusions. The BEPE questionnaire for the evaluation of the eight fundamental specific dimensions of the entrepreneurial personality presents adequate psychometric properties. Its relationships with other measures of personality traits are in line with what is expected. Therefore, the BEPE is a new measurement instrument that can be used with confidence both in the applied field and in research. (shrink)

O papel da Igreja foi fundamental no processo de constituição do território no Novo Mundo. Neste artigo, explora-se a forma como se implementaram no Novo Reino de Granada (hoje Colômbia) as “Instruções para a fábrica e decoração das igrejas” de Carlos Borromeo de 1577, documento considerado como a consolidação arquitetônica do Concilio de Trento. A análise parte da comparação dos principais preceitos contidos nas Instruções com os contratos de fabricação das igrejas celebrados pelo Visitador Luis Henríquez entre os anos 1599 (...) e 1605 no território da Província de Tunja. Dentro da empreitada religiosa e de unificação da Coroa espanhola no território americano, a doutrina dos indígenas americanos tornou-se um projeto crucial e, portanto, a fabricação das igrejas e a concentração da população. A igreja era o ponto de partida para a conformação de novos assentamentos para indígenas sob a responsabilidade de um padre, chamados “povoados de índios”. A força do projeto secular espanhol deixou suas marcas na forma destas igrejas de doutrina construídas e que, 400 anos depois, permitem realizar uma reflexão sobre a imposição do simbolismo e da hierarquia eclesiástica em Colômbia. Palavras-chave: Arquitetura religiosa. Novo Reino de Granada. Carlos Borromeo. Igrejas de doutrina.In the territorial constitution of the New World the role of the Church was crucial. In this article, we investigate the implementation in the new kingdom of Granada (the current Colombia) the “Instructions to the factory and decoration churches” by Charles Boromeo, 1577, a document considered as architectural consolidation of the Council of Trent. This analysis is grounded in the comparison between the Borromeo's Instructions and the numerous contracts assigned by Luis Henriquez in the period of 1559 and 1605, in the territory of the province of Tunja. The indoctrination process of the indigenous American people became the main project in the religious enterprise and unification of Spanish Crown through the construction of sturdy churches and concentration of this population around them. The church was the start point for urban conformation of new indigenous settlements named “povoados de índios”, upon the responsibility of a priest. The force of Spain’s secular project left its mark in the shape of such “churches of doctrine” constructed across the territory in the XVII century, which allow today a reflection about the symbolic imposition of a new ecclesial hierarchy in Colombia during this period.

El artículo plantea varias cuestiones a la obra de José Antonio Suárez, catalogada dentro del formato mínimo y la micrografía. Se analizan las causas de la atracción por lo mínimo: la perfección de la joya, la magia del talismán, el oficio, el truco, los modelos editoriales de la ilustración. Se aborda el recurso a la privacidad del diario de apuntes, el rechazo a la producción del gran arte y al mismo tiempo la admiración por el arte museal. Finalmente (...) se evalúan las posibilidades que da el grabado al formato mínimo. (shrink)

Esta reseña artística, escrita especialmente por Carlos Arturo Fernández Uribe, está dedicada a un artista que tiene una innegable importancia en el espíritu de la marginalidad tipográfica. Fernández Uribe comenta los ejercicios que José Antonio Suárez dedicó a los vaciados de la colección Pizano, copias de obras clásicas utilizadas durante mucho tiempo en las clases de pintura y escultura de la Universidad Nacional de Colombia. Las relaciones entre el homenaje, el centón, la apropiación y la copia que van (...) de la literatura y la filosofía a las artes visuales son más que evidentes. (shrink)

El presente trabajo propone una introducción a la doctrina de la ciencia matemática de Francisco Suárez según sus Disputaciones Metafísicas I. El contexto de la investigación aborda la noción de objeto adecuado, una teoría de la abstracción y el orden de las ciencias especulativas en general. Por ello, para mejor comprender las ciencias matemáticas, es necesario observar su relación con la metafísica, delimitando no solo su fundamento, sino también su horizonte especulativo.

El presente trabajo propone una introducción a la doctrina de la ciencia física de Francisco Suárez en sus _Disputaciones Metafísicas I_. El contexto de la investigación aborda la noción de objeto adecuado, una teoría de la abstracción y el orden de las ciencias especulativas en general. Por ello, para mejor comprender las ciencias físicas, es necesario observar su relación con la metafísica, delimitando el fundamento, el horizonte y las divisiones de la filosofía natural.

Resumen: En las Disputationes Metaphysicae XIII, X-XIV Francisco Suárez expone su parecer sobre la incorruptibilidad de los cielos. Particularmente, la sección XI, 13-34 reviste capital importancia de acuerdo con un tópico contextual: la incipiente revolución copernicana y el quebrantamiento de las tesis fundamentales aristotélicas. Su confutación, ubicada principalmente en las D.M. XIII, XI, 13, constituye la piedra angular que le permitirá al Dr. Eximio continuar sosteniendo una posición metafísica-cosmológica de cuño aristotelizante.

De acuerdo con las D.M. de Francisco Suárez, la ciencia metafísica ha perdido su horizonte. Por esta razón el tratado del Dr. Eximio principia con un estudio de la filosofía primera donde paulatinamente se atenderán las dificultades emergentes relativas a una consideración de las ciencias especulativas. De ese modo la claridad alcanzada en derredor de la metafísica colocaría las bases necesarias para evitar –o tratar de corregir– los errores en teología sagrada por su vinculación necesaria con la filosofía primera. (...) Asimismo, el esclarecimiento del objeto adecuado de la metafísica conlleva la necesidad de evidenciar para la razón aquellos propios de las demás ciencias, configurándose así una división y relación entre ellas en sede objetiva. A su vez este panorama aparece expresado con total claridad en las D.M. I, I, 14-15 sobre el que exclusivamente se hará foco. (shrink)

El presente artículo tiene como propósito presentar una reflexión pedagógica mediante la aplicación de referentes del pensamiento de Juan José Bautista, discípulo de Enrique Dussel. Se busca repensar en términos epistemológicos la enseñanza del locus de enunciación latinoamericano. Se tiene en cuenta que el proceso de desarrollo y consolidación de la razón moderna como forma de compresión de la realidad latinoamericana ha destruido sistemáticamente otras formas de pensar, incluidas las de los pueblos originarios americanos. Es por eso que este (...) artículo busca introducir la reflexión sobre los compromisos que implican pensar y pertenecer a esta zona geográficamente diversa. (shrink)
