Cell division is an universal process the aim of which is the equitable distribution of subcellular organelles from single cells to their daughters. The extraordinary accuracy with which the genetic material is partitioned requires a complex machinery involving many gene products. Genetic approaches can be used to identify the relevant components and processes, and mutational analysis of loci essential for cell division has been carried out in several eukaryotes, in particular fungi and mammalian cells in culture. Recently, this type of (...) analysis has been extended to Drosophila, an ideal eukaryote for genetic studies. We will review here the genetic dissection of mitosis in Drosophila melanogaster, discussing recent findings of interest and the methodological problems that have been encountered. (shrink)

Federations are concerned about attracting new sportsmen and sportswomen and increasing the number of members. The purpose of this research was to describe karate federations' strategies for attracting and retaining members through happiness. The analysis was carried out by designing a structural equation modeling, which allowed to analyze the main variables that influenced the happiness of the karate athlete and consequently to study their effect on people's loyalty to sports federations. In particular, Partial least squares SEM was applied in an (...) overall model when it was possible to understand the happiness role in relation with other traditional relevant variables on loyalty. The data were obtained through primary sources employing a survey sent to the autonomous federations in the discipline of karate, obtaining a sample of 682 federated members in Spain. The results of the model revealed that consumer satisfaction, engagement, and meaningful influence on consumer happiness, but engagement was the most important and relevant variable for affecting this variable. Finally, consumer satisfaction and consumer happiness influence loyalty, and consumer satisfaction was the most important variable, but consumer happiness showed a real alternative for improving loyalty in karate sports federations. Then, one of the implications of this work was that it helped to explain how the federations can be managed to achieve loyal consumers together with a more considerable increase in the number of federated members.

The purpose of the present study is to examine the attitudes of Portuguese chartered accountants with respect to questions of ethical nature that can arise in their professional activity. Respondents were asked to respond to the Ethics Position Questionnaire developed by Forsyth (Journal of Personality and Social Psychology 39(1), 175–184, 1980), in order to determine their idealism and relativism levels. Subsequently, they answered questions about five scenarios related to accounting practices, with the objective of measuring their ethical judgments. Based on (...) the idealism and relativism levels of our respondents, they were classified into one of four groups, representing different ethical ideologies (absolutism, exceptionism, subjectivism, and situationism). The results indicated that age was the major determinant of relativism. Contrary to previous research, older respondents revealed themselves significantly more relativistic than younger ones. Gender seems to be the most important determinant of ethical judgments; against expectations, men evidenced significantly stricter judgments than women in two of the five scenarios. Findings also indicated that respondents’ ethical judgments did not differ significantly based on their ethical ideology, supporting the idea that ethical ideology is not an important determinant of ethical judgments.

Nesta resenha são apresentados alguns pontos fundamentais do livro de Tracie Matysik When Spinoza Met Marx: Experiments in Nonhumanist Activity. Na obra, a autora analisa detidamente alguns pensadores ligados à tradição alemã pós-Hegel: Heinrich Heine, Berthlod Auerbach, Moses Hess, Karl Marx, Johann Jacoby, Jakob Stern e Gueorgui Plekhanov. Seu foco é o modo como todos esses utilizaram o pensamento de Espinosa para compreender a noção de atividade e a possibilidade de transformação social. Espinosa era fundamental para o tema, pois seu (...) pensamento permitiria unir a ação humana à sua completa determinação frente à necessidade presente na natureza, duas ideias indispensáveis para um século no qual a ciência se desenvolvia rapidamente e para um país que acabara de presenciar as revoluções nas terras vizinhas. Matysik, então, nos oferece a oportunidade de entender a riqueza do espinosismo, dadas as inúmeras possibilidades de interpretação das obras do filósofo neerlandês, utilizadas tanto para fins revolucionários quanto reformistas. Além disso, a partir da segunda metade do livro, a autora nos convoca para discutir as relações entre a filosofia da completa determinação e os movimentos com raízes no socialismo marxista, apresentando os principais problemas que surgiam - e ainda surgem - para os autores que buscavam traçar tal conexão.

El cambio climático es uno de los mayores desafíos a los que nos enfrentamos en el siglo XXI. Los niños, niñas y adolescentes son especialmente vulnerables a sus efectos y han levantado su voz exigiendo justicia climática y un mayor reconocimiento en esta lucha ante la falta de atención de los estados. Aunque se han mejorado sus derechos para participar en la toma de decisiones, todavía no se han visto acciones concretas, especialmente en el sur global. En este artículo se (...) propone el concepto de «reconocimiento recíproco de capacidades» como una manera de empoderar a los niños, niñas y adolescentes. Se concluye que es fundamental abordar este reconocimiento a nivel micropolítico. (shrink)

Nesta obra, Patrick J. Geary, professor emérito de História na Universidade da Califórnia, que dedicou a sua vida académica ao estudo da História Medieval, apresenta-nos as suas “reflexões sobre a relação entre os mitos dos povos europeus e as realidades do nacionalismo contemporâneo” (p. 7). A narrativa que Patrick J. Geary nos oferece tem um objectivo claro e assumido: desmontar os mitos nacionalistas e contribuir para a prevenção do seu reaparecimento e/ou fortalecimento.

In this paper I intend to argue that Prince Andrei Bolkonsky, one of the lead characters of the novel War and Peace, by Leo Tolstoy, can be taken as a Schopenhauerian hero.

A review of Alejandro Llano's book, Sueño y vigilia de la razón, is attempted on this article. To this aim it presents five main ideas from which it is possible to go beyond modernity limits to reach a new realistic philosophical framework.

Se plantea un trabajo de problematización socio-filosófica de la dimensión mediática de nuestros modos contemporáneos de coexistencia que retoma la perspectiva analítico-crítica formulada por Michel Foucault. En primer lugar, se considera la problematicidad de la ausencia de una indagación en profundidad al respecto en su obra; y se enfocan los escasos lugares en los que él mismo se refirió a la temática, especialmente sus indicaciones relativas a la emergencia de la noción de “público” como una dimensión particular de la población. (...) En segundo lugar, se abordan los modos en que su pensamiento ha sido retomado por pensadores contemporáneos que han situado la centralidad de las técnicas comunicacionales de poder, como Maurizio Lazzarato y Byung-Chul Han, y que se han planteado la necesidad de avanzar más allá sirviéndose en ambos casos de las propuestas de Gilles Deleuze sobre las sociedades de control. En particular, se sitúa cómo los conceptos de “biopolítica” y “biopoder” de Foucault son reformulados para construir nociones, tales como las de “noopolítica” y “psicopolítica”, que buscan dar cuenta de las formas de poder que se ejercen ya no sobre los cuerpos sino primariamente sobre la mente o la psique.

The present introduction contains a short scientific biography describing the many different areas of logic and computation where Luis contributed significant advances. (shrink)

We give an account of stable reasoning, a recent and novel approach to problem solving from a formal, logical point of view. We describe the underlying logic of stable reasoning and illustrate how it is used to model different domains and solve practical reasoning problems. We discuss some of the main differences with respect to reasoning in classical logic and we examine an ongoing research programme for the rational reconstruction of human knowledge that may be considered a successor to the (...) logical empiricists’ programme of the mid-twentieth century.

O sermão número 48, “O dia santificado” (Sermo XLVIII: Dies Santificatus), proferido em Mainz na data de 6 de Janeiro de 1445, na Festa da Epifania do Senhor, traz alguns temas de interesse na compreensão do desenvolvimento da filosofia cusana no período imediatamente posterior à obra A douta ignorância (De docta ignorantia, 1440) e As conjecturas (1442). Este sermão é citado no opúsculo A busca de Deus (De querendo deum, I, 16, 3), de 1445, como sendo a primeira tentativa cusana (...) de tratar do tema dos “modos de conhecimento” (modi cognoscendi) a partir da perspectiva do tema da “luz e das cores”, caro à tradição de comentadores escolásticos do De anima aristotélico, tentativa essa que viria a ser aprimorada no referido opúsculo. Nele, Cusa busca uma “conjectura” capaz de simbolizar a relação paradoxal de imanência e transcendência entre Deus e a criação, mediante a relação que se estabelece entre a luz sensível e as cores do arco-íris. A luz, embora explicada em suas determinações, isto é, nas cores, ainda permanece transcendente às mesmas, as complicando enquanto luz pura. Do mesmo modo, Cusa evoca o exemplo do “sentido comum” da tradição escolástica, que em sua interpretação neoplatonizante, seria responsável por “complicar” todos os sentidos. Por fim, mediante tais exemplos da luz e dos sentidos, Cusa encaminha sua reflexão à visão do “modo de ser divino”, que, segundo ele, também poderia ser intuído no exemplo do nome divino IHWH. Esse nome inominável que complica todos os nomes, assim como os exemplos tratados, simboliza aquela realidade divina que complica e explica todas as coisas. A reunião desses exemplos é abalizada por uma coleção de citações escriturais, que buscam trazer respaldo às suas interpretações. (shrink)
