The aim of this study was to carry out a psychosocial analysis of child-to-parent violence (CPV) in a sample of school adolescents, considering a set of individual variables (psychological distress, problematic use of social networking sites, and perceived non-conformist social reputation) and family variables (open and problematic communication with parents) according to sex. The sample consisted of 3,731 adolescents (54% boys), aged between 14 and 16 years (M = 14.6 years, SD = 0.567), from the state of Nuevo León, Mexico. (...) The scores of the boys and girls were analyzed to check for differences. Also, correlations between all the study variables were calculated. Finally, a multiple stepwise regression analysis was carried out for the total sample and also for boys and girls separately. Results confirmed the important role of individual variables as predictors of CPV in boys and girls. The main difference between boys and girls was observed in the predictive weight of problematic use of social networking sites, which was higher in girls than in boys. Open communication with the father was a significant factor for predicting the decrease of CPV levels in the case of boys, while open communication with the mother predicted the decrease of CPV in girls. Problematic communication with the mother showed similar values in boys and girls when predicting CPV, however, the predictive weight of problematic communication with the father was higher in girls than in boys. These results are interesting and have important implications for the prevention of CPV. (shrink)

An iterative learning control algorithm is presented for the force control circuit of a hydraulic cushion. A control scheme consisting of a PI controller, feed-forward and feedback-linearization is first derived. The uncertainties and nonlinearities of the proportional valve, the main system actuator, prevent the accurate tracking of the pressure reference signal. Therefore, an extra ILC FF signal is added to counteract the valve model uncertainties. The unknown valve dynamics are attenuated by adding a fourth-order low-pass filter to the iterative learning (...) control design, which is split up into two second-order low-pass filters to carry out forward and backward filtering and obtain zero-phase filtering. The addition of the ILC signal presents significant improvements in terms of settling time and overshoot of the pressure signal in the cylinder. (shrink)

On Carlos Moya's Reply to the Argument from Luck Resumen: Esta nota crítica se centra en el argumento de Carlos Moya (2017, 168-70) a favor de la conclusión de que el Argumento de la Suerte representa en realidad un problema mayor para los compatibilistas que para los libertaristas. La Sección 1 introduce brevemente el Argumento de la Suerte. La Sección 2 discute la distinción de Moya entre dos concepciones de deliberación práctica, y propone una manera alternativa a la (...) de Moya de entender la crítica al libertarismo que se basa en la condición de que cualquier decisión libre debe tener una explicación contrastiva. Finalmente, la Sección 3 resume la respuesta libertarista de Moya al Argumento de la Suerte, y sugiere un modelo alternativo de determinismo que Moya podría considerar para completar su argumento. Palabras clave: libre albedrío, Argumento de la Suerte, libertarismo, compatibilismo, explicación contrastiva, determinismo. Abstract: This review focuses on Carlos Moya’s (2017, 168-70) argument for the conclusion that the Argument from Luck actually represents a greater problem for compatibilism than for libertarianism. Section 1 briefly introduces the Argument from Luck. Section 2 discusses Moya’s distinction between two conceptions of practical deliberation, and suggests a justification that Moya does not consider for the condition that any free decision must have a contrastive explanation. Finally, Section 3 summarizes Moya’s libertarian response to the Argument from Luck, and suggests an alternative model of determinism that Moya might consider to complete his argument. Keywords: free will, Argument from Luck, libertarianism compatibilism, contrastive explanation, determinism. (shrink)

This book introduces readers to central concepts and ideas in Mexican philosophy. Couched in stories and anecdotes from the author's life, the book offers these concepts and ideas as orientations, recommendations, or exhortation for navigating today's world. The structure and the style of the book aims at making these accessible to both specialists and non-specialist or anyone who may have had some experience with contemporary forms of marginalization, alienation, objectification, or any of the various forms of dread and accidentality familiar (...) to modern life. This, the author thinks, is most of us. Narrowing down the scope of the tradition, the author draws from the history of Mexican philosophy in the 20th century, as it is at this time that Mexican philosophy comes into its own. The book begins with two short introductions, one is an introduction philosophy in Mexico, the other to Mexican philosophy. Here, readers are introduced to Alfonso de la Veracruz, who offered the first philosophy course in the Americas in 1540 in the monastery of a small town in Michoacán, Mexico. From there, it presents four main themes from Mexican philosophy that recur in the philosophical literature. The remainder of the book serves as a "guide" for living a better, more fulfilling life. The main characters in what the author considers an uncontroversial retelling of Mexican philosophy are Antonio Caso, Samuel Ramos, Emilio Uranga, Leopoldo Zea, Jorge Portilla, Rosario Castellanos, Elsa Cecilia Frost, and, of course, persons in the author's own life.

The purpose of the paper is to present a logical framework that allow to formalize a kind of prima facie duties, defeasible conditional duties, indefeasible conditional duties and actual (indefeasible) duties, as well as to show their logical interconnections.

Resenha do livro “Raízes do Conservadorismo brasileiro: a abolição na imprensa e no imaginário social”, escrito por Juremir Machado da Silva e publicado pela Editora Civilização Brasileira em 2017.

Resumen: Este artículo sostiene que la regla en el mundo social es el cambio, en todas las escalas de tiempo, sin ciclos ni periodicidades. Por consiguiente, el tema que emerge inmediatamente es la irregularidad del mundo. Si esto es cierto, deben ser posibles unas ciencias sociales irregulares. El mejor antecedente para una idea semejante se encuentra en la comprensión del propio Mandelbrot acerca de los fractales y multifractales. Las ciencias sociales tratan radicalmente, de fenómenos irrepetibles, singulares. Estos han sido llamados (...) como eventos raros. De esta suerte, una nueva epistemología emerge y es posible. Al final se muestra que existen nexos fuertes entre las ciencias sociales con la biología y la ecología. Pero en ese punto, el texto termina abierto.: This paper claims that change is the rule in the social world, in all scales of time, without cycles or periodic dynamics. Hereafter, the topic that immediately arises is the irregularity of the world. If this is true, then irregular social sciences are to be possible. The best antecedent of such an idea is to be found in Mandelbrot’s own understanding of fractals and multifractals. Thus, the social sciences radically deal with phenomena that are in no way repeated, for they are singular. Such events have been called as rare events. In thus tenure, a brand-new epistemology arises and is possible. At the end, some connections between the social sciences and biology and ecology are depicted. That, however, is where this text ends and remains open. (shrink)

No cartesianismo contemporâneo, devido à retomada da teoria da livre criação das verdades eternas, alguns intérpretes trazem ao debate internacional um interessante viés interpretativo do pensamento de Descartes. Segundo eles, ao apresentar a indiferença da vontade como atributo de Deus, Descartes instaura uma concepção totalmente perigosa, da qual derivam a incompatibilidade entre a indiferença divina e o sistema cartesiano, deflagrando, enfim, um irracionalismo radical.

Las nociones de "uno" y de "múltiple" han sido, históricamente, objeto de tratamiento, a la vez, filosófico y teológico. En el contexto de la filosofía islámica oriental, y en el marco de su vertiente más específicamente neoplatónica, el "Príncipe de los Teósofos", Sadrá Sirázi (ob. 1050/1640), estudia ambas desde una perspectiva ontológica y distanciándose del enfoque consignado al respecto por los filósofos peripatéticos del Islam. Adaptando y continuando, de un lado, la gnosis de 1km aI-'Arabi, y, de otro, la sabiduria (...) iluminativa de Sohravardi, MollA Sadrá discute la distinción aviceniana entre un Ser Necesario y una multiplicidad de seres posibles, así como la posibilidad de considerar accidental la realidad de la existencia. Basado en la eoimplicación de tres conceptos fundamentales: i~álat al-wu9ñd (prioridad del ser), i,vahdat al-wu9i2d (unidad del ser) y tagkik (diferenciación y gradación intensiva del ser), el univocismo monadológico de 5adrá puede, por otra parte, permitirnos reevaluar ciertas cuestiones filosóficas que pugnan por ser examinadas hoy a una nueva luz.

¿Cuál es la distancia mínima entre autor y obra? ¿Pueden unos números sucesivos trazados en un lienzo convertirse en el testimonio de una existencia? Estas y otras muchas preguntas emergen cuando se analizan las obras del pintor polaco Roman Opalka. Su proyecto OPALKA 1965/1-∞ constituye un hito en el arte contemporáneo por su intención de explorar la representabilidad de la duración del tiempo y del ser en su carácter existencial en relación a la muerte. La extrema longitud del proyecto, desarrollado (...) durante más de cuatro décadas, así como su aparente precariedad formal encierran un mensaje pleno de potencia que cuestiona la relación que tenemos con nuestra propia vida.

Cet article propose une interprétation de la philosophie de la Nouvelle Académie différente de celle qui a été défendue par J. Annas. Il nous semble que la prise en compte de l'ensemble des témoignages concernant cette école suggère une réalité plus complexe que celle que recouvre le concept de scepticisme, au moins dans sa version néopyrrhonienne. Nous croyons qu'Arcésilas et Carnéade n'ont pas délimité un Platon sceptique, mais qu'ils ont accepté à leur manière l'ensemble de l'héritage platonicien. La force de (...) la tradition apparaît donc plus forte dans l'histoire de l'Académie que ne l'admettent généralement les interprètes. The purpose of this article is to give an interpretation of the New Academy's philosophy quite different from the one defended by J. Annas. In our opinion the reading of the whole testimonies relating to this school suggests a greater complexity than what is embraced by the concept of skepticism, at least in its neopyrrhonian version. We believe that Arcesilas and Carneades, instead of confining Plato whithin the limits of skepticism, have accepted - in their own way - the whole Platonician legacy. Thus the burden of tradition seems more important in the history of the Academy than it is generally admitted. (shrink)

A fauna sul-americana evolveu durante dezenas de milhões de anos em isolamento dos outros continentes. Isso conferiu-lhe um carácter muito particular, comprovado pelo enorme número de táxones endémicos da divisão biogeográfica em que se inclue o sub-continente – Região Neotropical.Quando os descobridores e colonizadores abordaram e foram penetrando no Brasil, no século XVI e seguintes, deparou-se-lhes uma fauna – abundante na época –, diversificada e estranha ao seu conhecimento da fauna europeia, quando muito também de algumas espécies asiáticas e africanas. (...) As tendências reveladas pelos ‘colonizadores-naturalistas’ na descrição dessa fauna foram diferentes. Uns denominaram-na como se de espécies europeias ou africanas se tratasse. Outros reconheceram a sua originalidade, adoptando a nomenclatura etnobiológica dos Índios, a qual reproduziram em sons da língua portuguesa. Pêro de Magalhães Gândavo, o primeiro português a produzir obra impressa em que se descreve a fauna brasílica, seguiu ambas as vias, conforme os casos. É do seu relato, publicado em 1576, que se apresentam e comentam alguns excertos neste artigo.South American biodiversity evolved for tens of million years in isolation. A most special composition of its fauna and flora has been the result of such an isolation period, the number of endemic taxa being very large. Biogeographers soon recognized the singularity of South America, including this sub-continent in a biogeographical division of the highest rank - the Neotropical Region. When Portuguese discoverers and explorers, from the 16th century on, passed into Brazil, they found a diversified and exotic fauna quite different from the European or African ones that they eventually knew. Some of them, namely jesuits and other educated people, described the most common or conspicuous species, indicating the main edible or dangerous properties of each one. Ethnobiological nomenclature or the common names of the closer European or African species have been applied by those ‘naturalists’. The first of them recording his observations and speculations on a printed book was Pêro de Magalhães Gândavo, who lived in Brazil for a few years before 1561. Comments on his interesting book, entitled História da Província de Santa Cruz, are presented in this paper. (shrink)

Esta investigación da cuenta de cómo ha sido expresada, interpretada y fundada poéticamente la ciudad colombiana durante el siglo XX en las obras de los poetas colombianos Luis Vidales (Suenan Timbres), Rogelio Echavarría (El Transeúnte) y Juan Manuel Roca (Luna de ciegos y Los ladrones nocturnos). Indaga cómo estos tres poetas colombianos han fundado ciudades como textos escriturales y levantado cartografías simbólicas citadinas; realiza una interpretación de los universos de sus poéticas, de las constelaciones simbólicas que asume el poema como (...) universo del lenguaje, el cual construye topologías imaginarias sobre la ciudad, revelando arquetipos fundamentales, presentes en la poesía urbana colombiana.

O presente trabalho visa analisar a possibilidade de se utilizar a ontologia matemática, conforme se pode observar na obra de Badiou, para conformar a estrutura lógica de teorias sociais. Trata-se de exemplificar como o conceito de multiplicidade sem unidade pode substituir a noção grega tradicional de que a unidade é anterior à multiplicidade. Para isso se apresentam as inovações matemáticas de Cantor, com a teoria dos conjuntos, e Paul Cohen, que apresenta as noções de “genérico” e “forçamento”, as quais permitem (...) a concepção de uma multiplicidade sem unidade. Por fim, aborda-se a analogia levantada por William Widen que aproxima o raciocínio lógico-matemático utilizado pela teoria dos conjuntos ao método de “subtração” utilizado por John Rawls para a formação de sua teoria da justiça.
