Considerações históricas sobre o infinito e alguns de seus paradoxos

This research aims to elucidate some of the historical aspects of the idea of infinity during the creation of calculus and set theory. It also seeks to raise discussions about the nature of infinity: current infinite and potential infinite. For this, we conducted a survey with a qualitative approach in the form of exploratory study. This study was based on books of Mathematics' History and other scientific works such as articles, theses and dissertations on the subject. This work will bring the view of some philosophers and thinkers about the infinite, such as: Pythagoras, Plato, Aristotle, Galilei, Augustine, Cantor. The research will be presented according to chronological order. The objective of the research is to understand the infinite from ancient Greece with the paradoxes of Zeno, during the time which the conflict between the conceptions atomistic and continuity were dominant, and in this context that Zeno launches its paradoxes which contradict much a concept as another, until the theory Cantor set, bringing some paradoxes related to this theory, namely paradox of Russell and Hilbert's paradox. The study also presents these paradoxes mentioned under the mathematical point of view and the light of calculus and set theory

Sustentabilidade na educação corporativa e o desenvolvimento de competências societais

Em sua dimensão político-societal, competência começa a fazer parte da agenda dos modelos de desenvolvimento de pessoas nas organizações, sobretudo, sob o mote da sustentabilidade. Partindo dessa premissa, este artigo investiga se há conteúdo relevante por trás dessas propostas educativas ou se elas, simplesmente, tornam os pressupostos da sustentabilidade funcionais ao sistema corporativo sem que alguma mudança substancial esteja de fato em curso. Mais especificamente, este estudo se apoia em dois eixos: primeiro, procura discutir o conceito de competência societal; segundo, busca analisar uma experiência de educação executiva de desenvolvimento de gestores em questões relacionadas à sustentabilidade, o Programa de Desenvolvimento de Líderes para Sustentabilidade (PDLS). O estudo, de natureza qualitativa, foi conduzido em uma instituição financeira que se tornou destaque na mídia e passou a ser reconhecida como ator social destacado, por levar à frente a ideia de inserir a sustentabilidade na prática dos negócios. Os resultados revelam um programa impactante que se, por um lado, permitiu que o discurso dos gestores se tornasse competente, por outro, nem sempre correspondeu a uma ação que atingisse o mesmo patamar de excelência. Os gestores participantes adquiriram conhecimento e visão crítica, mas, ainda, enfrentam dificuldades para harmonizar os objetivos do negócio com princípios de sustentabilidade. Mesmo com formação avançada sobre o tema, os paradoxos da ação permanecem presentes quando se trata de dar vida a esta ideia força chamada sustentabilidade.

Marx and the Bible: José Miranda’s Critique of the Philosophy of Oppression

This paper critically examines the liberation theology of José Porfirio Miranda, as expressed in his Marx and the Bible (1971), with a focus on the central idea (and subtitle) of this work: the “Critique of the Philosophy of Oppression.” Miranda’s critique is examined via certain key tropes such as “power,” “justice,” and “freedom,” both in the context of late twentieth-century Latin American society, and in the state of the “post-Christian” and “post-Marxist” world more generally, vis-à-vis contemporary liberal justice theory. Close examination of the potentialities, paradoxes and subtle evasions in Miranda’s critique leads not to the conclusion that Miranda does not go far enough in his application of Christian principles to justice theory.

Childrens Participation and Citizenship in a Global Age. Empowerment, Tokenism or Discriminatory Disciplining?

This article explores children’s participation and citizenship, taking its point of departure in the empirical observation of a paradox: On the hand there is a general participatory climate and a growing commitment to empowerment of children, and on the other hand some children’s experience of discrimination, disciplining and distrust. The analysis is structured into three main parts: 1) Participation, approached from Hart’s Ladder of Participation and Bourdieu’s theorizing of power dynamics; 2) Rights, using Marshall’s tripartite conceptualization, namely civil rights, political rights and social rights, supplemented by a discussion of the right to care and cultural rights; and 3) Identity, theorized using Delanty’s conceptualization of citizenship as a learning process The article concludes that children’s citizenship, and the initiatives that are accounted for as facilitating their well being and participation though social work, too often tend towards tokenism if not discriminatory disciplining and exclusion, rather than empowerment, due to political, organisational and discursively shaped power relations.

Assibi A. Amidu 2009. Matrix Nominal Phrases in Kiswahili Bantu. A Study of their Effects on Argument Syntax.

Assibi A. Amidu's contribution is undoubtedly a highly challenging one to the direct study of the Kiswahili Bantu language. Aiming at complementing the existing grammars and monographs of living languages the author intends to illuminate some paradoxes of the Kiswahili syntax and morphology. Having defined this aim he presents a clearly structured monograph to the interested reader, consisting of six chapters, relating to one another.

Ar diffusion in K-feldspar: present and absent

The mechanisms of Ar release from K-feldspar samples in laboratory experiments and during their geological history are assessed here. Modern petrology clearly established that the chemical and isotopic record of minerals is normally dominated by aqueous recrystallization. The laboratory critique is trickier, which explains why so many conflicting approaches have been able to survive long past their expiration date. Current models are evaluated for self-consistency; especially Arrhenian non-linearity leads to paradoxes. The models’ testable geological predictions suggest that temperature-based downslope extrapolations often overestimate observed geological Ar mobility substantially. An updated interpretation is based on the unrelatedness of geological behaviour to laboratory experiments. The isotopic record of K-feldspar in geological samples is not a unique function of temperature, as recrystallisation promoted by aqueous fluids is the predominant mechanism controlling isotope transport. K-feldspar should therefore be viewed as a hygrochronometer. Laboratory degassing proceeds from structural rearrangements and phase transitions such as are observed in situ at high temperature in Na and Pb feldspars. These effects violate the mathematics of an inert Fick’s Law matrix and preclude downslope extrapolation. The similar upward-concave, non-linear shapes of Arrhenius trajectories of many silicates, hydrous and anhydrous, are likely common manifestations of structural rearrangements in silicate structures.

El laberinto del continuo del joven Leibniz y la paradoja de Aquiles y la tortuga

En este trabajo se considerarán los desarrollos de Leibniz en torno al laberinto del continuo en sus años de juventud (1671-1676). Nuestra intención es tratar de determinar el modo como puede comprenderse la solución leibniziana de la paradoja de Zenón conocida como Aquiles y la tortuga. Para esto, luego de presentar las paradojas, señalaremos la estructura general de la solución y tres grandes momentos de su aplicación que se estructuran en torno a los siguientes escritos: Theoria motus abstracti (1671), De minimo et maximo (1673) y el diálogo Pacidius Philalethi (1676)

El recurso de la paradoja en la Farsalia de Lucano

En el presente trabajo analizaremos algunas paradojas de la Farsalia, que ejemplifican la presencia de esta figura en una amplia diversidad de ámbitos (genérico, lingüístico, político, mítico - religioso y moral) y asimismo muestran su posición nuclear en el funcionamiento de la estructura semántica y formal de la epopeya. Los trabajos de F. Ahl (1976), W. Johnson (1987), A. Perutelli (2000), E. Narducci (2002) y S. Bartsch (1997; 2005) constituyen los principales referentes bibliográficos en su consideración de la importancia del empleo de la paradoja en la Farsalia

Las paradojas de nadie : Una genealogía del no-sujeto

Cada época histórica construye, a través de discursos y prácticas específicas, sus formas legitimadas de subjetividad. Sin embargo, por debajo de estas identidades institucionalizadas, se ha ido gestando a lo largo de la historia una forma paradójica de subjetividad cuyo nombre, desde Homero en adelante, es Nadie. Esta figura excéntrica hace posible, cada vez que reaparece en la trama de los discursos y las prácticas, la subversión de las categorías fundamentales de la ontología y la política que han definido al hombre históricamente. Este trabajo pretende reconstruir la genealogía de esta particular figura con el fin de mostrar la posibilidad de una lectura diferente (y paradójica) de algunos de los conceptos centrales de la metafísica de Occidente
