At the beginning of the 18th century, Berkeley believed an anomaly pointed out by Isaac Barrow could be regarded as important evidence against the optical theories that had been established and standardized thanks to the works of Kepler and Newton. In this article, we want to show that Berkeley’s treatment of the Barrovian Case does not falsify these theories. We will contend that the strategy used by Berkeley to resolve the anomaly by alluding to a change of convention is a (...) strategy that the classical theorist could use as well. In other words, the classical theorist could also appeal to a change of convention to deal with the problem. (shrink)

Johannes Kepler dedicated much of his work to discover a law for the refraction of light. Unfortunately, he formulated an incorrect law. Nevertheless, it was useful for anticipating the behavior of light in some specific conditions. Some believe that Kepler did not have the elements to formulate the law that was later accepted by the scientific community, that is, the Snell–Descartes law. However, in this paper, we propose a model that agrees with Kepler’s heuristics and that is also successful in (...) anticipating the behavior of light when it passes through a surface that separates two media with different optical densities. This model adopts strategies that were recommended by Kepler in two types of analogies. The obstacles that led to the failure of the two types of analogies are presented in the article, and we argue that the model proposed here could overcome these specific obstacles. Finally, we show how the proposed model could be articulated with Kepler’s metaphysics of light. (shrink)

El título reproduce las famosas frases de Friedrich Nietzsche y Michel Foucault, quienes de manera alegórica postulaban el agotamiento de dos conceptos centrales que tuvieron larga y fructífera vida en la historia de la humanidad. Para Nietzsche la muerte de Dios es la pérdida de la capacidad ordenadora del mundo, sustentada en una verdad concebida como metafísica y en una moral judeo-cristiana, cuyas raíces las busca el filósofo en la Grecia de Sócrates y Platón.Según Foucault, con la “muerte de Dios” (...) devendría también la muerte de su asesino, el hombre como sujeto de verdad, pues en el siguiente siglo de postmodernidad no aparecerá el esperado Superhombre de Nietzsche, sino la cada vez más devaluada figura del hombre como categoría ontológica, cediendo su lugar central a la primacía del lenguaje. Así, el hombre sale de la posición central en tanto objeto de conocimiento, del saber racional, un desplazamiento del hombre a su sola condición de sujeto pensante y productor de discursos, ya no como privilegiado objeto de dicho pensamiento.Foucault reconoce que es Nietzsche quien inaugura ese cambio de eje. Foucault con su formulación sobre el discurso, el saber y el poder, nos lleva finalmente al punto focal de su investigación, la constitución del sujeto dentro de una sociedad disciplinaria. Nietzsche y Foucault nutren y forman las dos caras de la misma moneda que nos encadena a la economía de la vida. Los sujetos, en ejercicio de nuestra libertad, podemos –como sujetos constituidos- adscribirnos totalmente al orden normativo y la seguridad que nos brinda el ámbito social de pertenencia o podemos –como sujetos constituyentes- utilizar nuestro juicio y ejercer una reflexión crítica de esa sociedad a la que pertenecemos.

Na atualidade estamos enfrentando uma forte onda de intolerância e tolerância, potencializando e valorizando a Tolerância como sendo um modelo a seguir, e seria a solução para as fortes condutas violentas, discriminatórias e criminosas que estamos sendo vítimas nas relações interpessoais e nas relações entre culturas e países. Tolerar o desigual, o assimétrico é uma luta desigual, do mais forte contra aquele que pela sua realidade social, tem sido enfraquecido. Como formar uma consciência e uma cultura, não do tolerar-aguentar a (...) partir de minhas condições impostas; mas uma cultura de hospitalidade, de acolhida, de abertura ao distante, ao assimétrico e estranho. A hospitalidade incondicional, ou seja, não coloco nenhuma condição, a única condição para acolher ao estrangeiro que chega do além do horizonte, é não ter condições. Desse modo não acolho uma categoria estrangeiro, mas uma pessoa que tem sua individualidade e sua unicidade. Para uma acolhida com hospitalidade é necessário criar um deslocamento na minha interioridade, me acomodar diferente, o outro que chega sempre provoca um movimento interior e exterior no meu eu; quando não acolho ao assimétrico, colocando condições na sua chegada, nada de novo acontece no eu. Acolher com hospitalidade é a possibilidade de nos experimentar diferente e de inaugurar algo novo em nós, na construção de sermos cada vez melhores, mais humanos, solidários e hospitaleiros. Palavras-chave: Tolerância, Intolerância, Hospitalidade condicional, Hospitalidade incondicional, Estrangeiro. (shrink)

En el artículo se examina la controversia entre extramisionismo e intramisionismo a propósito de la percepción visual. Se defiende que la evaluación del cierre de la controversia depende del explanandum que rastrea el filósofo/historiador en la reconstrucción que persigue. Si enfatizamos en los mecanismos causales, la controversia se cerró en favor del intramisionismo. Si enfatizamos en aspectos asociados con la intencionalidad o con la forma como ciertas afecciones mentales refieren a objetos externos, la controversia conduce a una conciliación entre intramisionismo (...) causal y extramisionismo mental. Finalmente, si ponemos en duda la necesidad de una distinción entre interno/externo, la controversia se disuelve por carecer de sentido. (shrink)

This article presents the analysis of the characteristics of labor well-being in Colombian micro and small enterprises, this was developed through a documentary review from the model of Hoyos (2010), it is a qualitative research, where 42 investigations were collected, which were consulted in databases such as: Science Direct, Refseek, Redalyc, Scielo, Google Scholar and Dialnet, in addition to exploring the repositories of Colombian universities such as: UNAD, Uniminuto, ECCI, Usanbuenaventura, EAFIT, Unipiloto, UGranada, UTecnológica, UJavieriana, UAndes, UCatólica, UNIR, among others, (...) of which, 13 were adjusted with the categories: Practices of Labor Well-being, Theories of Labor Well-being, Needs in Collaborators and Sociodemographic Data, then descriptive synoptic sheets were constructed and then an analysis by category matrix was made, finally, a data analysis was carried out with the ATLAS.ti tool, which allows discerning the object of study through semantic networks. In this order, it is found that activities related to communication, incentives and motivation are part of the activities used as work welfare practices; as for the theoretical positions of well-being at work, the most supported is the one given by the WHO (2010), which is also defined from satisfaction and quality of life; Among the most outstanding needs to develop welfare programs is dissatisfaction in communication with colleagues and managers, ignorance of the responsibilities in their position, among others, on the other hand, there is evidence of a disregard to establish sociodemographic profiles, that is, companies do not consider it when planning or implementing workplace welfare actions. It concludes the need to build labor welfare policies and practices sensitive to the cultural and economic context for Colombian companies, this means recognizing the importance of adaptive and pragmatic approaches in microenterprises and the integration of more structured and theoretical approaches in small enterprises.

The objective of this research was to systematize the results of existing publications on basic recreational activities in Basic Education students during the years 2019 to 2023. The method adopted in the research was a review of the scientific literature, based on a documentary design, involving the stages that include exploring the sources, carrying out the filtering process to select the most significant and relevant studies, then interpreting the results and subsequently analyzing them. The type of research was a systematic, (...) retrospective, observational review. The databases considered were Scopus, Scielo, EBSCOHOST and Sciencedirect. As inclusion and exclusion criteria, studies from the last 5 years were taken into account, which considered the research variables taking them in a general or specific way and no books, theses or conference documents were taken. The presentation of the results was used following the PRISMA method adapted from the year 2020. The results of the systematic review allowed us to theoretically associate the recreational physical activities carried out by basic education students with personal perception, motivation, psychosocial aspects and social barriers that constitute factors. conditions for its execution.

Localization Wireless Sensor Networks (WSN) represent a research topic with increasing interest due to their numerous applications. However, the viability of these systems is compromised by the attained localization uncertainties once implemented, since the network performance is highly dependent on the sensors location. The Node Location Problem (NLP) aims to obtain the optimal distribution of sensors for a particular environment, a problem already categorized as NP-Hard. Furthermore, localization WSN usually perform a sensor selection for determining which nodes are to be (...) utilized for maximizing the achieved accuracy. This problem, defined as the Sensor Selection Problem (SSP), has also been categorized as NP-Hard. While different metaheuristics have been proposed for attaining a near optimal solution in both problems, no approach has considered the two problems simultaneously, thus resulting in suboptimal solutions since the SSP is biased by the actual node distribution once deployed. In this paper, a combined approach of both problems simultaneously is proposed, thus considering the SSP within the NLP. Furthermore, a novel metaheuristic combining the Black Widow Optimization (BWO) algorithm and the Variable Neighbourhood Descent Chains (VND-Chains) local search, denominated as BWO-VND-Chains, is particularly devised for the first time in the author’s best knowledge for the NLP, resulting in a more efficient and robust optimization technique. Finally, a comparison of different metaheuristic algorithms is proposed over an actual urban scenario, considering different sensor selection criteria in order to attain the best methodology and selection technique. Results show that the newly devised algorithm with the SSP criteria optimization achieves mean localization uncertainties up to 19.66 % lower than traditional methodologies. (shrink)

Hoy nos movemos en un mundo altamente cambiante y atestado de desarrollo científico, técnico y tecnológico. Un mundo condicionado por los intereses de una globalización económica, donde el imperativo es consumir, y donde aquellos que producen de manera individual y distinta son absorbidos, en el mejor de los casos, o anulados por el sistema capitalista. Ahora bien, ese estado de cosas ha puesto en riesgo de pérdida al sujeto racional heredado y caracterizado desde la modernidad y que es requerido hoy (...) día como sujeto de racionalidad tecnológica. El sujeto-persona-agente racional se encuentra en una encrucijada ante la sociedad de consumo y el sistema económico de producción. La encrucijada consiste en si sigue aceptando el ser considerado y utilizado como un objeto, cosa, instrumento, artefacto más dentro del sistema artefactual o recobrar la capacidad de racionalidad, heredada desde la Modernidad y refrendada como racionalidad tecnológica desde la Revolución Industrial.

People’s awareness of tactile stimuli has been investigated in far less detail than their awareness of stimuli in other sensory modalities. In an attempt to fill this gap, we provide an overview of studies that are pertinent to the topic of tactile consciousness. We discuss the results of research that has investigated phenomena such as “change blindness”, phantom limb sensations, and numerosity judgments in tactile perception, together with the results obtained from the study of patients affected by deficits that can (...) adversely affect tactile perception such as neglect, extinction, and numbsense. The similarities as well as some of the important differences that have emerged when visual and tactile conscious information processing have been compared using similar experimental procedures are highlighted. We suggest that conscious information processing in the tactile modality cannot be separated completely from the more general processing of spatial information in the brain. Finally, the importance of considering tactile consciousness within the larger framework of multisensory information processing is also discussed. (shrink)

Culture has traditionally been considered as a set of knowledge, beliefs, arts, laws, norms, and morals, acquired by a human being as a member of a group. Some anthropologists interpret this as a set of abstract representations, such as information or knowledge, while others interpret it as behavioral control mechanisms. These views assume that the contents of a particular culture must be processed by the minds of individuals, either in a direct way or by resorting to learned mental structures in (...) processes of symbolic socialization. Some critics suggest a problem with these perspectives since they do not provide a convincing explanation of the enculturation process beyond metaphorical images of transfer or internalization of symbolic cultural contents through linguistic transmission. The new embodied theories of cognition, especially enactivism, could give new ideas about what enculturation processes are like, through the concept of participatory sense-making in material culture environments. In this essay, we discuss how an enactive vision of culture could be, and what advantages it would have, as well as the challenges and weaknesses in explaining the culture and its learning processes.

The United Nations’ increasing involvement in global sustainability culminated in 2015 with the release of the 2030 Agenda. This agenda puts businesses in the spotlight, and their innovation and stakeholder partnering activities are portrayed as essential strategies for achieving an ambitious set of 17 Sustainable Development Goals. In this study, we identify six distinct dynamic stakeholder engagement strategies—resilient specialists, opportunity explorers, uncommitted diversifiers, rainbow warriors, rainbow washers, and progressive learners—and distinguish two approaches to innovate, depending on the range of SDG (...) targets aimed to achieve simultaneously. On the one hand, for firms that take a narrow approach intended to achieve a reduced set of SDG targets, we predict that successful dynamic stakeholder engagement strategies are those that end up with an intensive collaboration with a reduced number of stakeholder groups. On the other hand, for firms adopting a broad innovation approach to satisfy a wide set of SDG targets, we predict that successful dynamic stakeholder engagement strategies are those that end up interacting with a wide number of stakeholder groups. Longitudinal analysis of more than 3900 Spanish firms supports our predictions and suggests clear implications for responsible innovation research and the advancement of sustainable development through collaboration.

This article shows how the ethical framing of the contemporary issue of modern slavery has evolved in UK construction, a sector in which there is a high risk of labor exploitation. It also examines how these framing dynamics have inhibited the emergence of a common framework of action to deal with the issue. We draw on both framing theory and the literature on the discursive construction of moral legitimacy. Our longitudinal analysis reveals that actors seeking to shape the debate bring (...) their own moral schemes to justify and construct the legitimacy of their frames. Actors cluster their views around five evolving frames: human rights issue (later shifting to hidden crime), moral issue, management issue (later shifting to human moral obligation), social justice issue, and decent work issue—which promote particular normative evaluations of what the issue is, who is responsible, and recommendations for action. Our study contributes to a dynamic and political understanding of the meaning making of modern slavery. We identify the antecedents and conditions that have forestalled the emergence of new patterns of action to tackle modern slavery in the UK construction sector thereby evidencing the effects of the interplay of morally competing frames on field-level change.

Focusing especially on Science and the Modern World, this article explores Whitehead's understanding of the social contexts and repercussions of mathematical and scientific abstraction. It investigates his remarks on the need to offset pernicious practices of abstraction in the context of a renewed concern with the link between conceptuality and materiality in social theory. Whitehead's inquiry into the problematic legacy of Galileo and scientific materialism is then contrasted with a different diagnosis of the abstractive maladies of modern society, the one (...) put forward under the Marxist rubric of `real abstraction'. While both stances allow us to explore the social repercussions of abstractive practices, it is argued that an understanding of the practically abstract character of capitalism permits us to identify the limits of Whitehead's pedagogical wish to reform our culture of abstraction.

Este artículo, producto de un proyecto financiado por la Fundación Cajacanariasy la Asociación Cultural TuSantaCruz, analiza las perspectivas juveniles acerca de la realidad social, política y económica que marcan las diferentes trayectorias de vida de la juventud que habita en Santa Cruz de Tenerife. El uso del concepto de joven que hacemos en este trabajo es más abierto de lo habitual, pues concebimos que la juventud es una categoría social atravesada por cuestiones como el origen social, el nivel de estudios (...) y la clase social, por lo que no es un colectivo caracterizado únicamente por un aspecto biológico-generacional. La metodología utilizada es de tipo cualitativa, concretamente se ha empleado la técnica denominada grupos de discusión.This article, that was a product of a project funded by the Cajacanarias Foundation and the TuSantaCruz Cultural Association, analyzes the youth perspectives of the social, political and economic realities that affect at different life trajectories of youth that lives in Santa Cruz de Tenerife. Note that the use made of the concept of youth is more open than usual, because in this communication we conceive that youth is a social category traversed by issues such as social origin, educational level and social class, so this group is not only a group characterized by biological-generational relationships. The methodology used is qualitative, specifically we have used the technique called focus groups. (shrink)

La razón fundamental por la que, según cierto modelo historiográfico el Parménides platónico constituye un diálogo de crisis en el desarrollo del pensamiento de Platón, es la supuesta presencia en él de una crítica de la Teoría de las Ideas del período medio –Fedón, Banquete, República. La insuficiencia de esa teoría consistiría en una concepción de las Ideas como unidades absolutamente simples y completamente aisladas que les impediría cumplir la función para la cual habrían sido concebidas. Esa función solo podría (...) ser cumplida por una nueva concepción relacional de las Ideas que estaría sugerida en el Parménides y desarrollada en el Sofista. Así pues, por contraste con la que yo llamaría una estrategia del silencio, quisiera 1) insistir en que la noción de koinōnía es fundamental e imprescindible para el proyecto de la República, pues su tema central, la noción de justicia, es impensable sin la noción de koinōnía entre las Ideas; y 2) hacer notar el uso de esa noción de justicia en el Parménides, precisamente en conexión con la cuestión de la interrelación eidética y la concepción de la Idea como un todo “que ha surgido como un uno a partir de todos las partes – ἐξ ἁπάντων ἓν τέλειον γεγονός”.
