The theory of rough sets starts with the notion of an approximation space , which is a pair ( U , R ), U being the domain of discourse, and R an equivalence relation on U . R is taken to represent the knowledge base of an agent, and the induced partition reflects a granularity of U that is the result of a lack of complete information about the objects in U . The focus then is on approximations of concepts (...) on the domain, in the context of the granularity. The present article studies the theory in the situation where information is obtained from different sources. The notion of approximation space is extended to define a multiple-source approximation system with distributed knowledge base , which is a tuple , where N is a set of sources and P ranges over all finite subsets of N . Each R P is an equivalence relation on U satisfying some additional conditions, representing the knowledge base of the group P of sources. Thus each finite group of sources and hence individual source perceives the same domain differently (depending on what information the group/individual source has about the domain), and the same concept may then have approximations that differ with the groups. In order to express the notions and properties related with rough set theory in this multiple-source situation, a quantified modal logic LMSAS D is proposed. In LMSAS D , quantification ranges over modalities, making it different from modal predicate logic and modal logic with propositional quantifiers. Some fragments of LMSAS D are discussed and it is shown that the modal system KTB is embedded in LMSAS D . The epistemic logic is also embedded in LMSAS D , and cannot replace the latter to serve our purpose. The relationship of LMSAS D with first and second-order logics is presented. Issues of expressibility, axiomatization and decidability are addressed. (shrink)

Resumen La relación que siempre ha existido entre la filosofía y el lenguaje es una zona que nos interesa explorar. La imagen de la metáfora como figura que se contextualiza en este ensayo, tiene como presupuesto el origen occidental del acto especular y la concurrencia que lo metafórico ha tenido en este tan particular período del pensamiento. -/- Lo metafórico, entonces, se convierte en el nudo gordiano que se comienza a develar en tanto esta problematización hace aparición en el texto (...) poético como fuente genera triz de lo que posteriormente será el discurso filosófico occidental, que en su lectura fundacional atisba el caos pero cae con posterioridad en un irreversible proceso de secularización en el cual la metáfora también jugó y juega hasta hoy un muy importante desempeño. -/- Abstract The relationships that there has always been between philosophy and language is a zone we are interested in exploring from the image of the metaphor as a figure which it is contextualized in this essay having its basis on the western origin of the speculative act and the repetitiveness that the metaphoric has had in that particular period of thought. -/- The metaphoric then become the gorgian node which start to reveal as this puzzle appears in the poetic text as a generative source of the following philosophical western discourse which in its foundational reading views the chaos but it falls later in a irreversible process of secularization in which the metaphor also played and play until today an important execution.

This paper is a defence of a holistic version of the generalist view of moral reasoning based on prima facie principles. In Section 1 I summarise Dancy’s arguments for particularism. Then I argue that particularism goes against strong intuitions regarding reasoning in general (Section 2), fails to account for the asymmetry of reasons (Section 3) and to make sense of compunction and moral imbecility (Section 4). I conclude (Section 5) that a holistic generalism is the right view of moral reasoning. (...) Then I discuss Dancy’s objections to it. I argue that Dancy’s appeal to default reasons is philosophically equivalent to a holistic version of generalism, and hence incompatible with particularism (Section 6) and that his resistance to accept holistic generalism is the result of a foundationalist view of reasoning (Section 7). As an alternative to foundationalism I defend an Aristotelian dialectical view of moral reasoning. (shrink)

SummaryThis article is a defense of a semantic concept of incommensurability. Davidson's criticism of the dualism of scheme and content and Ramberg's davidsonian pragmatic concept of incommensurability are discussed. It is argued that Davidson's argument against conceptual relativism fails to undermine the notion of two languages being mutually partially not translatable. It is then claimed that a non‐trivial concept of semantic incommensurability based on the notion of intranslatability does makes sense, does not presuppose the scheme‐content dualism and is consistent with (...) an objectivist view of progress in science. It is then concluded that, although the widely held view that the incommensurability thesis entails some form of epistemological relativism must be rejected, it does follow from Davidson's criticism of the “third dogma” of empiricism that a sharp distinction of the kuhnian kind between “normal” disagreement and conceptual change can not be drawn.

¿Puede ser racional creer algo porque se quiere creerlo? Prima facie no, puesto que una creencia racional se basa en razones, y la voluntad de creer puede ser una causa, pero no una razón de la creencia. Sin embargo, algunos intentos de autoinducirse creencias causalmente pueden verse como el ejercicio de una racionalidad de segundo orden. En este artículo, se esboza una visión de esta racionalidad de segundo orden basada en la tesis de Davidson de la división de la mente (...) y la distinción de Ortega entre ideas y creencias. La inquietante conclusión del análisis es que la capacidad de tener deseos de segundo orden sobre nuestras creencias es lo que hace posibles tanto la autocrítica y la autosuperación como el dogmatismo y la autocorrupción y que la condición de posibilidad de la racionalidad y la libertad es la misma que la de la irracionalidad y la alienación. Is it rational to believe something because one wants to believe it? Prima facie it is not, for a rational belief is based on reasons, and the will to believe can be a cause, but not a reason for the belief. Nevertheless, some attempts of causally self-inducing beliefs can be viewed as a sort of second-order rationality. This paper sketches a view of this second-order rationality based on Davidson's thesis of the divided mind and Ortega's distinction between ideas and beliefs. The uncomfortable conclusion of the discussion is that the ability to have second-order beliefs about our beliefs is what makes possible both self-criticism and self-improvement and dogmatism and self-corruption and that the possibility condition of rationality and freedom and of irrationality and alienation are the same.

Este artigo aborda os diferentes estilos educativos parentais, objetivando subsidiar reflexões sobre a parentalidade e a adaptação psicossocial das crianças diante da pandemia. A fundamentação teórico-conceitual está baseada nos estilos educativos parentais a partir da abordagem tipológica. De acordo com a literatura, pais com um estilo (...) educativo autorizativo e indulgente podem contribuir para que as crianças enfrentem adversidades de maneira mais adaptativa. (shrink)

a elaboração de uma ontologia fenomenológica era uma possibilidade inscrita no próprio projeto filosófico husserliano. Em que sentido, no entanto, o espírito da máxima da ?volta às coisas mesmas? serviu de inspiração ao retorno à questão do ser? Em que medida as elaborações ontológicas que se atribuíram o título de fenomenológicas permaneceram fiéis ao espírito geral e às diretrizes formais do pensamento de Husserl? É na tentativa de responder a essas questões que nos propomos examinar a posição especial de Heidegger (...) face ao problema da articulação da ontologia com a fenomenologia. Nossa preferência é ditada pela própria originalidade do emprego da fenomenologia, no autor de Ser e Tempo. O exame do sentido que assume a fenomenologia enquanto ontologia da compreensão, cujo instrumento é a hermenêutica da existência fáctica do homem, exige previamente o delineamento do projeto filosófico fundamental heideggeriano.

In this paper we study the distribution of power in the Basque Parliament since the restoration of the Spanish democracy. The classic simple games do not fit with the particular voting rule that it is used to invest the president of the regional government. In order to model this voting mechanism we incorporate coalitional externalities to the game. We use the extensions of the most popular power indices to games with externalities that have been proposed in the most recent literature. (...) Moreover, we propose a method to estimate the probability of a given coalition based on the ideological positions of its members in a two-dimensional political spectrum. (shrink)

Objectives To describe the distress experienced by Spanish podiatrists related to ethical dilemmas, organisational matters, and lack of resources. Design A 2008 email survey of a representative sample of 485 Spanish podiatrists presenting statements about different ethical dilemmas, values and goals at the workplace. Results The response rate was 44.8%. Of all the respondents, 57% described sometimes having to act against their own conscience as distressing. Time constraints is the main cause of moral distress (67%) and 58% of respondents said (...) that they found it distressing that patients have long waits for treatment. Distress related to inadequate treatment due to economical constraints or ineffectiveness was described by 60% of the podiatrists. Another 51% reported that time spent on administration and documentation is distressing. Female doctors experienced more distress than their male colleagues. Last, 36% of respondents reported that their workplace lacked strategies for dealing with ethical dilemmas. Conclusion These study results identify moral distress among Spanish podiatrists mainly related to time constraints, patient demands and lack of resources. Moral distress varies with sex and age. Organisational strategies such as moral deliberation and responsive evaluation offer the potential to address moral distress. (shrink)

C.S. Peirce defended a pragmatist view of assertion in terms of its normative effect. This paper has two goals. First, to reconstruct and assess Peirce’s argument for the thesis that to assert a proposition is to make oneself responsible for its truth. Second, to argue that Peirce interpreted “responsibility for truth” as the acquisition of a dialogical commitment, namely, the duty to defend the proposition asserted by giving reasons upon challenge.

El presente artículo tiene como principal objetivo introducir al lector algunos de los conceptos fundamentales de la filosofía de Gottlob Frege. Estos son: el binomio sentido/referencia, el valor veritativo de oraciones con elementos no referenciales, la distinción entre pensar, juzgar y aseverar, su concepción de los indéxicos y los demostrativos, así como su defensa de la existencia de un tercer reino. En algunos de ellos se mostrarán algunas problemáticas asociadas que han sido destacados por pensadores de renombre. Tal es el (...) caso, por ejemplo, de la famosa crítica de Bertrand Russell a la semántica de Frege por su incapacidad para dar cuenta del valor de verdad de oraciones ficticias. Dirigido especialmente al lector lego en la materia, aunque sin perder rigor académico, este trabajo procura presentar algunas de las principales tesis fregeanas a través de sus fuentes primarias.

Based on published works and unpublished materials, this article analyses how cybernetics was received by two Spanish thinkers exiled in Mexico: José Gaos (1900–1969) and Eduardo Nicol (1907–1990). This reception is particularly intriguing especially when considering the substantial presence and social impact that Norbert Wiener had in Mexican society because of his friendship with Arturo Rosenblueth. Gaos and Nicol are the first philosophers to develop a complex and original diagnosis of cybernetics in Mexico. It will be shown how the exiled (...) thinkers take on the philosophical implications of this science in the light of their respective theoretical projects, and finally, it will be defended how the critical perspective they develop is particularly significant for Mexico’s political and academic context since it illuminates some negative aspects of cybernetics that Wiener did not foresee and that had not been reported there until then.

La intención de este artículo será proponer una lectura tentativa del papel del mesianismo que sea acorde con la centralidad del concepto de experiencia y redención en Walter Benjamin y, al mismo tiempo, que sea capaz de dar con las tensiones teóricas propias de la maceración materialista de su pensamiento, así como la influencia inequívoca de problemas de cuño kantiano en la conformación de la atomización de la experiencia de la modernidad diagnosticada por Benjamin. Para ello, nos fijaremos en una (...) de las últimas y más acabadas modulaciones del concepto de crítica inmanente en la figura del historiador dialéctico tal y como es abordada en El libro de los Pasajes.

Karl Popper postula que no puede haber una teoría científica del desarrollo histórico que sirva de base para la predicción. Para mejorar la sociedad es necesario recurrir a la ingeniería social gradual, que busca introducir cambios tentativos, en sí mismos valiosos, al margen de que exista o no un plan general. Si no se obtiene el resultado esperado, habrá oportunidad de rectificar. El progreso gradual, la necesidad de un equilibrio de fuerzas bajo el poder del Estado, y la proporción entre (...) Estado y sociedad son vitales para la conservación de la libertad. La base teórico-social se ilustra con el ejemplo de un país imaginado, en el cual luego de un comienzo promisorio, que parecía dirigido a la construcción de una sociedad más justa, se abandonó el gradualismo, surgieron las ilusiones utópicas y terminó por apartarse de toda planificación. Palabras clave: Estado; falsacionismo; gradualismo; historicismo; ingeniería social; libertad; marxismo; planificación; sociedad; utopía. Popper and freedom. Once upon a time there was a country that went off courseKarl Popper argues that there can be no scientific theory of historical development on which historical prediction might be grounded. In order to improve society it is necessary to resort to gradual social engineering, which seeks to bring about tentative changes, valuable in themselves, regardless of whether or not there exists a general plan. If one does not reach the expected result, there will be room for rectification. Gradual progress, the need for a balance of the forces under the State’s power, and the balance between State and society are vital for the preservation of freedom. The social-theoretical basis is illustrated with the example of an imaginary country, which after a promising start -seemingly aimed at building a more just society-, simply gave up gradualism, utopian illusions emerged, and finally all planning was abandoned. Keywords: State; falsationism; gradualism; historicism; social engineering; freedom; marxism; planning; society; utopia. (shrink)

Resumen: La teoría de probabilidad rara vez diferencia su concepto de su determinabilidad cuantitativa. Para definir su objeto, ésta comienza por la exposición abstracta de la probabilidad y sus determinaciones o bien referidas a la esfera del ser, o bien a la esfera del pensar. Este estudio pretende, siguiendo el automovimiento de estas determinaciones en la Lógica, criticar la limitación de ambas proposiciones y presentar una concepción especulativa del fenómeno probabilístico.

La filosofía del siglo XX apenas puede entenderse sin lo que tiene de constatación de una grave crisis. Transformaciones históricas de largo alcance como la redefinición del Estado burocrático, la irrupción de la cultura de masas o el despliegue de la técnica industrial modificaron sustantivamente la experiencia que los hombres tenían de sí mismos y del mundo.La ambivalencia de esos cambios en lo que tienen, por un lado, de hitos de progreso racional, y, por otro, de verdaderas amenazas para el (...) bienestar de los hombres, obliga a que el pensamiento filosófico reconsidere lo que pueda quedar del hombre como sujeto de la razón moderna. La centralidad de la humanidad como sujeto de una historia pretendidamente racional, ¿ha quedado definitivamente atrás y apenas resta más que recordarla como una vana ilusión? ¿Es de todo punto inevitable que antes o después los logros de la humanidad se conviertan en procesos ciegos que podrían llegar a destruirla? Este libro trata de responder a estas preguntas, y a las que surgen de su hilo con- ductor, de la mano de la losofía del siglo XX. Autores de la talla de José Luis Pardo, Santiago Alba Rico, César Rendueles, Pablo López o Eduardo Maura, entre otros, agitan los términos de un debate que nos concierne a todos. (shrink)

paradigma estabelecido pela dualidade de “palavras-princípio” Eu-Tu e Eu-Isso, a intuição axial do pensamento dialógico de Martin Buber se constitui como pedra angular de sua obra sobre religião: a dupla disposição de um homem-Eu e de Deus-Tu fundada num encontro recíproco. A fé – Glauben - é a resposta do homem a Deus, no encontro no qual Ele se mostra pela Palavra como Tu Eterno na revelação como mistério de Presença. Buber propõe duas maneiras opostas de crer: de um lado, (...) a Emunah, como confiança pessoal ou abandono confiante de um povo, Israel, que se deixa guiar por Deus e, de outro lado, a Pistis, a qual, segundo o apóstolo Paulo, é a adesão individual a um conteúdo de fé, de um credo tido por verdadeiro. Os dois modos de crer, embora haja diversidade nos conteúdos de fé, podem ser apreendidos a partir de experiências vividas: tenho confiança em alguém e reconheço um fato como verdadeiro. Para tais experiências, não se consegue “dar razão” ou justificá-las. O objetivo desta comunicação é apresentar, de maneira sucinta, o pensamento de Martin Buber sobre essa questão que pode ilustrar o seu entendimento das relações entre o Cristianismo helenista e o Judaísmo. Palavras-chave: Emunah ; Pistis ; Fé; Martin Buber. (shrink)

Não importa nossa crença ou descrença, que nosso anseio à sabedoria tome a forma de uma meditação sobre a vida ou uma meditação sobre a morte, quando esta irrompe como um ladrão, sem avisar o dia e a hora, não nos é possível frear um sentimento de estupor e de tristeza. A morte do Rubem, tirado do afeto dos seus, excluído da amizade de seus colegas, é daquelas que provocam a incompreensão diante da injustiça do destino.

The Marvel Cinematic Universe has brought many of the best-known Marvel Comics stories to the big screen. But just because they use these stories it doesn’t mean they reproduce them faithfully. As it has been seen over the years, Marvel Studios’ film projects follow their own storylines that do not correspond to the main narrative of the comics. Starting from this premise, this research aims to study the evolution to Thor: Love and Thunder (Waititi, 2022) from the comic book series (...) Thor: The Butcher of Gods (Aaron, 2018) on which it is based. Focusing both on what aspects they share and the differences that make Thor: Love and Thunder a standalone project. (shrink)

In an ever more transparent, digitalized, and connected environment, customers are increasingly pressuring brands to embrace genuine corporate social responsibility practices and co-creation activities. While both CSR and co-creation are social and collaborative processes, there is still little research examining whether CSR can boost co-creation. In addition, while previous research has mainly related co-creation to emotional outcomes, limited empirical research has related it to rational and behavioral outcomes. To address these shortcomings in the literature, this paper examines the influence of (...) CSR on customer loyalty, considering the mediating roles of co-creation and customer trust. It also investigates the influence of co-creation on customer trust. The data were collected in Spain in late 2017 using an online survey, and the sample contained 1101 customers of health insurance services brands. Structural equation modeling was used to test the hypothesized relationships simultaneously. The results show that CSR influences customer loyalty both directly and indirectly through co-creation and customer trust. However, the indirect impact is the stronger of the two, implying that embracing co-creation activities and developing customer trust can make it easier for CSR practices to enhance customer loyalty. In addition, co-creation has a direct effect on customer trust. (shrink)

In order to be competitive in an era of ethical consumerism, brands are facing an ever-increasing pressure to integrate ethical values into their identities and to display their ethical commitment at a corporate level. Nevertheless, studies that relate business ethics to corporate brands are either theoretical or have predominantly been developed empirically in goods contexts. This is surprising, because corporate brands are more relevant in services settings, given the nature of services, and the fact that services settings comprise a greater (...) number of customer–brand interactions and touch points than goods contexts. Accordingly, the purpose of this article is to empirically examine the effects of customer perceived ethicality of corporate brands that operate in the services sector. Based on data collected for eight service categories using a panel of 2179 customers, the hypothesized structural model is tested using path analysis. The generalizability theory is applied to test for measurement equivalence between these categories. The results of the hypothesized model show that, in addition to a direct impact, customer perceived ethicality has a positive and indirect impact on brand equity, through the mediators of recognition benefits and brand image. Moreover, brand heritage negatively influences the impact of customer perceived ethicality on brand image. The main implication is that managers need to be aware of the need to reinforce brand image and recognition benefits, as this can facilitate the translation of customer perceived ethicality into brand equity.

The recent rise in ethical consumerism has seen increasing numbers of corporate brands project a socially responsible and ethical image. But does having a corporate brand that is perceived to be ethical have any influence on outcome variables of interest for its product brands? This study analyzes the relationship between perceived ethicality at a corporate level, and brand trust, brand affect and brand loyalty at a product level. A theoretical framework with hypothesized relationships is developed and tested in order to (...) answer the research question. Data have been collected for 45 product categories in the fast moving consumer goods sector using a panel of 4,027 Spanish consumers. The proposed relationships are tested using structural equations modeling. The results suggest there is a positive relationship between perceived ethicality of a brand and both brand trust and brand affect. Brand affect also positively influences brand trust. Further, brand trust and brand affect both show a positive relation with brand loyalty. The managerial and academic implications of the results are discussed. (shrink)

In recognition of the central place that the concept of tragedy holds in the historical understanding of culture and society, this paper features an analysis of its presence, current state, and value in the digital environments of the postmodern era, with special attention to videogames. Thus, the overcoming of a classic model of tragedy in the cybertextual condition is first determined, along with the discursive dimension underlying said overcoming. To this end a theoretical statement to the issue of tragedy is (...) proposed, from the perspective of the cybertext as procedural rhetoric. This will establish the formulation of a semiotic analytical model that problematizes Greimas’ actantial system under the light of the digital and interactive reality of videogames. To avoid this constraint, we propose to attach a new variable to the base of the generative trajectory: the “configurative synthesis,” product of the so-called “gaming/playing function.” This addition will integrate the figures of the game and the player in the dynamic distinction of the “quasi-Actant.” Finally, a sample of 79 cases will be observed in regards to the implications of the cybertextual notion of tragedy to the narrative and discourse of videogames.

Educational accompaniment, an expanded view from personalist anthropology In today's educational landscape, the digital transformation is a methodological, pedagogical and, undoubtedly, relational challenge. In this environment, there are proposals that advocate accompaniment as a means of facing this challenge. Moreover, we could say that accompanying is fashionable, with the risk that this implies of limiting and even sweetening its true meaning and scope. To avoid this, we propose to look at the nature of the human being and rediscover what he (...) really needs in his process of personal growth. This article presents an analysis of educational accompaniment, revealing its internal dynamism, making explicit the essential conditions that make it possible and proposing some pedagogical applications that shed light on the mission of accompaniment. From this personalist and profound point of view, accompaniment is proposed as a response to the anthropological need of being human and is configured as a path of encounters oriented towards the fullness of the person.
