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)

Cultural evolution studies are characterized by the notion that culture evolves accordingly to broadly Darwinian principles. Yet how far the analogy between cultural and genetic evolution should be pushed is open to debate. Here, we examine a recent disagreement that concerns the extent to which cultural transmission should be considered a preservative mechanism allowing selection among different variants, or a transformative process in which individuals recreate variants each time they are transmitted. The latter is associated with the notion of “cultural (...) attraction”. This issue has generated much misunderstanding and confusion. We first clarify the respective positions, noting that there is in fact no substantive incompatibility between cultural attraction and standard cultural evolution approaches, beyond a difference in focus. Whether cultural transmission should be considered a preservative or reconstructive process is ultimately an empirical question, and we examine how both preservative and reconstructive cultural transmission has been studied in recent experimental research in cultural evolution. Finally, we discuss how the relative importance of preservative and reconstructive processes may depend on the granularity of analysis and the domain being studied. (shrink)

Cultural evolution researchers use transmission chain experiments to investigate which content is more likely to survive when transmitted from one individual to another. These experiments resemble oral storytelling, wherein individuals need to understand, memorize, and reproduce the content. However, prominent contemporary forms of cultural transmission—think an online sharing—only involve the willingness to transmit the content. Here I present two fully preregistered online experiments that explicitly investigated the differences between these two modalities of transmission. The first experiment (_N_ = 1,080 participants) (...) examined whether negative content, information eliciting disgust, and threat-related information were better transmitted than their neutral counterpart in a traditional transmission chain setup. The second experiment (_N_ = 1,200 participants) used the same material, but participants were asked whether or not they would share the content in two conditions: in a large anonymous social network or with their friends, in their favorite social network. Negative content was both better transmitted in transmission chain experiments and shared more than its neutral counterpart. Threat-related information was successful in transmission chain experiments but not when sharing, and finally, information eliciting disgust was not advantaged in either. Overall, the results present a composite picture, suggesting that the interactions between the specific content and the medium of transmission are important and, possibly, that content biases are stronger when memorization and reproduction are involved in the transmission—as in oral transmission—than when they are not—as in online sharing. Negative content seems to be reliably favored in both modalities of transmission. (shrink)

A completeness theorem is established for logics with congruence endowed with general semantics (in the style of general frames). As a corollary, completeness is shown to be preserved by fibring logics with congruence provided that congruence is retained in the resulting logic. The class of logics with equivalence is shown to be closed under fibring and to be included in the class of logics with congruence. Thus, completeness is shown to be preserved by fibring logics with equivalence and general semantics. (...) An example is provided showing that completeness is not always preserved by fibring ligics endowed with standard (non general) semantics. A categorial characterization of fibring is provided using coproducts and cocartesian liftings. (shrink)

The branching-time logic called Peircean by Arthur Prior is considered and given an infinite axiomatization. The axiomatization uses only the standard deduction rules for tense logic.

In the tree-like representation of Time, two histories are undivided at a moment t whenever they share a common moment in the future of t. In the present paper, it will first be proved that Ockhamist and Peircean branching-time logics are unable to express some important sentences in which the notion of undividedness is involved. Then, a new semantics for branching-time logic will be presented. The new semantics is based on trees endowed with an indistinguishability function, a generalization of the (...) notion of undividedness. It will be shown that Ockhamist and Peircean semantics can be viewed as limit cases of the semantics developed in this paper. (shrink)

Apartándose de la interpretación humanista /metafísica, la comprensión originaria de la estética, la ética y la lógica que expone Heidegger lleva consigo un nuevo humanismo centrado en torno a la idea de Gelassenheit. Pero Gelassenheit, núcleo del habitar poético del hombre, es también la esencia de la experiencia artística originaria que es verdaderamente una poética de la receptividad del ser, es decir, una experiencia ética y ontológica originaria.

The nature of pre-reflective self-consciousness—viz., the putative non-inferential self-consciousness involved in unreflective experiences, has become the topic of considerable debate in recent analytic philosophy of consciousness, as it is commonly taken to be what makes conscious mental states first-personally given to its subject. A major issue of controversy in this debate concerns what pre-reflective self-consciousness is an awareness of. Some scholars have suggested that pre-reflective self-consciousness involves an awareness of the experiencing subject. This ‘egological view’ is opposed to the ‘non-egological (...) view’, according to which the subject, in being pre-reflectively self-conscious, is just aware of their own occurrent mental state. In this paper, I argue in favour of the egological view. The argument I develop is a qualified version of a line of reasoning originally provided by Rosenthal and builds on a proper clarification of the ontological status of token mental states. More precisely, I argue that token mental states are structured ‘fact-like’ entities having their subject among their constituents. Accordingly, one cannot be aware of one’s own occurrent mental state without thereby being aware of oneself. (shrink)

We show that the maximal linear extension theorem for well partial orders is equivalent over RCA0 to ATR0. Analogously, the maximal chain theorem for well partial orders is equivalent to ATR0 over RCA0.
