A systematic and comprehensive introduction to the study of nonlinear dynamical systems, in both discrete and continuous time, for nonmathematical students and researchers working in applied fields. An understanding of linear systems and the classical theory of stability are essential although basic reviews of the relevant material are provided. Further chapters are devoted to the stability of invariant sets, bifurcation theory, chaotic dynamics and the transition to chaos. In the final two chapters the authors approach the subject from a measure-theoretical (...) point of view and compare results to those given for the geometrical or topological approach of the first eight chapters. Includes about one hundred exercises. A Windows-compatible software programme called DMC, provided free of charge through a website dedicated to the book, allows readers to perform numerical and graphical analysis of dynamical systems. Also available on the website are computer exercises and solutions to selected book exercises. See www.cambridge.org/economics/resources. (shrink)

This work analyzes of clear, brief and simple way the important role of Communication nowadays in the called “Third Sector” or “Social Economy Sector”, which is composed by voluntary organizations , that develop selflessly social activities. The complicated relationships between these private and nonprofit organizations and the mass media, the need to take a proper communication strategy with them and the influence of new technologies as channels of “alternative communication” are the main topics discussed from an expert in Law´s point (...) of view.

Este articulo pretende brindar elementos sobre el tema de las identidades puestas al servicio de proyectos políticos y económicos. Es, conforme a una costumbre de quien firma este artículo, un diálogo entre el pasado y el presente, a la vez que se hace un esfuerzo de contextualización. El patriotismo emerge como coartada de intereses económicos, dejando una cauda de odios, sobre los que se debe pensar y contribuir a actitudes de hermanamientos. Esta colaboración se centra en el nuevo colonialismo hispano, (...) de índole ultraconservador, aunque no están exentas otras fuerzas del espectro político. El trabajo, sobre todo, se centra en colaboraciones periodísticas críticas del ultraconservadurismo, por lo que se inscribe en un análisis de medios de comunicación. A modo de tipologías de fuentes podemos resaltar el texto de la BBC que muestra la preocupación hispana sobre la postura del Gobierno de Biden que recuerda la vieja pugna hispanismo-panamericanismo; el texto de Miriam Hernández Reina como asiento referencial de los nuevos aires de la ultraderecha española en América Latina; la combinación de los intereses políticos y económicos de dicha tendencia política en clave colonial, así como las preocupaciones del mundo de las izquerdas y ciertas pautas a seguir para contrarrestar la influencia creciente de la extrema derecha en las redes sociales.

El ensayo encuentra su sentido en la proximidad que tiene con el acontecimiento, la experiencia formativa y “con lo provisorio de la vida misma.” Surge de la reflexión de la práctica como docente universitario, en la vivencia del educador, en su actuar pedagógico reflexivo. Situado en la dinámica generativa: método/camino/ensayo/travesía/búsqueda/estrategia, se aproxima por medio de la observación y conceptualización a lo efímero, lo contingente, la novedad, la multiplicidad; fundamentado en principios métodológicos que dan cuenta de una iniciación en el (...) pensar complejo. Asumiendo los principios del pensamiento complejo a manera de conceptos sensibilizadores, se busca comprender la interacción educativa. Por último, se desarrollan temáticas emergentes, que pueden ser asumidas en próximas reflexiones e investigaciones sobre las múltiples y diferenciadas experiencias y acontecimientos formativos universitarios.

Un día de verano en medio de un insólito vendaval murió mi madre. Fue una extraña tarde de junio de torrencial lluvia y abrumadores rayos. “Tiene poca lividez, pero está muerta”, dijo el médico luego de auscultarla, tomarle el pulso, mirarle el reflejo pupilar a la velocidad de la luz y concluir: “Muerte súbita. Feneció de un ataque al corazón”.

La Sociedad Española de Historia Natural nació en 1871 como una asociación privada de naturalistas (geólogos y biólogos), con la pretensión de publicar una revista en la que dar a conocer sus estudios sobre la flora, gea y fauna española. En las décadas siguientes alcanzó un considerable número de socios, los Anales que publicaba adquirieron considerable prestigio y reunió una notable Biblioteca. Con el cambio del siglo la Sociedad consiguió una notable influencia en medios oficiales: se le concedió en 1903 (...) el título de Real, influyó en el diseño de los planes de estudios de la Sección de Naturales de la Facultad de Ciencias y los reglamentos del Museo Nacional de Ciencias Naturales, etc. A finales de los años veinte la Sociedad publicaba tres revistas científicas (Boletín, Memorias y Conferencias y Reseñas). En los años previos a la Guerra Civil la Sociedad acogió a todos aquellos investigadores, profesores, ingenieros, médicos, etc., interesados en las Ciencias Naturales. Tras décadas de esfuerzos por mantener su actividad, la Sociedad, desde 1971, ha luchado por fortalecer su actividad científica y académica. (shrink)

Se sintetiza los grandes problemas de la historiografía del XVI y deja al lector la reflexión abierta sobre la situación historiográfica actual. Las similitudes y divergencias entre las angustias y apuestas de aquellos historiadores y los de hoy, esto es, la percepción de la realidad y del pasado por medio de la Historia, ¿son aún iguales?

La invitación hecha en el segundo semestre de 2022 para participar en este dosier de Co-herencia suponía, entonces, por un lado, el sometimiento de los comentarios de Volkening a la obra en proceso de Gómez Dávila a un primer escrutinio crítico y, por el otro, la apertura a la discusión sobre crítica literaria y el pensamiento en Colombia y a consideraciones sobre formas alternativas de escritura crítica, como las ofrecidas por el ensayo literario, el diario y los géneros marginales y (...) fragmentarios. El llamado invitaba a considerar la pertinencia de un tema lleno de posibilidades, que permite relacionar la pregunta por la escritura, la lectura, la institucionalización y la recepción literaria con las perspectivas que prodiga un diálogo entre dos intelectuales colombianos, actualizado gracias a su publicación casi medio siglo después. Surgía de este modo la opción de descubrir, no solo un objeto de estudio de interés, sino también nuevos caminos críticos para los problemas del campo literario, editorial e intelectual colombiano.

This text is an interview given by Prof. Dr. Alfredo Pereira Jr. to Leonardo Ferreira Almada, on the occasion of the call for publication of interviews with different Brazilian philosophers. In response to the goal of the Trans/Form/Ação journal call, we sought to carry out an interview in which a PhD professor with an established career presents some elements of his personal and academic stories, as well as clarifies important points of his research, some of his theses and vision (...) of the world based on questions asked by another professor, a historical research partner, and in-depth knowledge of the interviewee’s career.

The Critique of Pure Reason—Kant’s First Critique—is one of the most studied texts in intellectual history, but as Alfredo Ferrarin points out in this radically original book, most of that study has focused only on very select parts. Likewise, Kant’s oeuvre as a whole has been compartmentalized, the three Critiques held in rigid isolation from one another. Working against the standard reading of Kant that such compartmentalization has produced, The Powers of Pure Reason explores forgotten parts of the First (...) Critique in order to find an exciting, new, and ultimately central set of concerns by which to read all of Kant’s works. Ferrarin blows the dust off of two egregiously overlooked sections of the First Critique—the Transcendental Dialectic and the Doctrine of Method. There he discovers what he argues is the Critique’s greatest achievement: a conception of the unity of reason and an exploration of the powers it has to reach beyond itself and legislate over the world. With this in mind, Ferrarin dismantles the common vision of Kant as a philosopher writing separately on epistemology, ethics, and aesthetics and natural teleology, showing that the three Critiques are united by this underlying theme: the autonomy and teleology of reason, its power and ends. The result is a refreshing new view of Kant, and of reason itself. (shrink)

The importance of the collective management of immaterial resources is a key variable in the valorisation of products in a post-industrial economy. The purpose of this paper is to analyse how, in post-industrial economies, it is possible to devise alternative forms of mediation between producers and consumers, such as organic farmers' markets, to curb the appropriation of rent by transnational and/or local business elites from the value created by immaterial resources. More specifically, we analyse those aspects of the collective management (...) of ethical values that, in the case of organic farmers' markets, can be a strategic source of competitive advantage for local producers. In this paper, the Ecomercado de Granada is studied as an example of mediation between production and consumption in a post-industrial economy. (shrink)

Hegel is, arguably, the most difficult of all philosophers. To find a way into his thought interpreters have usually approached him as though he were developing Kantian and Fichtean themes. This book demonstrates in a systematic way that it makes much more sense to view Hegel's idealism in relation to the metaphysical and epistemological tradition stemming from Aristotle. The book offers an account of Hegel's idealism in light of his interpretation, discussion, assimilation and critique of Aristotle's philosophy. There are explorations (...) of Hegelian and Aristotelian views of system and history; being, metaphysics, logic, and truth; nature and subjectivity; spirit, knowledge, and self-knowledge; ethics and politics. No serious student of Hegel can afford to ignore this major interpretation. It will also be of interest in such fields as political science and the history of ideas. (shrink)

Philosophers of perception frequently assume that we see actual states of affairs, or facts. Call this claim factualism. In his book, William Fish suggests that factualism is supported by phenomenological observation as well as by experimental studies on multiple object tracking and dynamic feature-object integration. In this paper, I examine the alleged evidence for factualism, focusing mainly on object detection and tracking. I argue that there is no scientific evidence for factualism. This conclusion has implications for studies on the phenomenology (...) and epistemology of visual perception. (shrink)

El objetivo del presente texto es llegar a una descripción clara y comprensiva de la forma budista de abordar la cuestión cognitiva. La palabra cognición se refiere aquí al proceso por el cual se desenvuelve la convicción de que algo es "verdadero". El examen budista de la cognición puede, a su vez, ser encarado como una forma de buscar mayor libertad y distanciamiento frente a los pensamientos, opiniones y tendencias propios.

L'analyste des discours qui surgissent au sein de conflits sociaux, de controverses, de débats publics, a souvent le sentiment qu'il n'observe pas des 'camps' correspondant à des groupes d'individus, mais des agencements qui doivent être considérés indépendamment des intentions, des stratégies ou des opinions de ceux qui y sont impliqués. Pour décrire les processus dans lesquels se constituent ces configurations conflictuelles, on fait alors appel à des combinaisons conceptuelles plus ou moins heureuses. À partir de l'hypothèse selon laquelle les conflits (...) sociaux évoluent par le renforcement/affaiblissement de la disponibilité de types d'actions, ce livre se propose de construire une théorie sémantique qui permette d'éclairer les mécanismes à l'œuvre dans les dynamiques sociales structurées par des tensions, d'interroger les liens entre discours et actions humaines, et d'explorer les conditionnements de la formation sociale du politique"--Page 4 of cover.

Abstract: Research on the nature and varieties of the format of cognitive representations in philosophy and cognitive science have been partly shaped by analogies to external, public representations. In this paper, we argue that relying on such analogies contributes to framing the question of cognitive formats in problematic, potentially counterproductive ways. We show that cognitive and public representations differ in many of their central features, making analogies to public representations ill-suited to improving our understanding of cognitive formats. We illustrate these (...) points by examining two case studies in which analogies to public representations may have had a negative impact on research: the 80’s-90’s debate about compositionality and cognitive architecture between symbolicists and connectionists; and contemporary discussions about the nature of visual demonstratives. Finally, we outline an alternative, computational account of formats that does not share the shortcomings of appeal to public representations. (shrink)

During the last years, there has been an important discussion on the concept of mental disorder. Several accounts of such a concept have been offered by theorists, although neither of these accounts seems to have successfully answered both the question of what it means for a certain mental condition to be a disorder and the question of what it means for a certain disorder to be mental. In this paper, I propose an account of the concept of mental disorder that, (...) if I am right, provides satisfactory answers to both of these questions. Furthermore, this account (unlike other accounts presented in the literature on the subject) meets the requirements for achieving a crucial goal underlying the project of sorting out the concept of mental disorder, namely the goal of allowing the existence of a dialogue between mental health professionals of different theoretical orientations. To achieve this goal, the account herein proposed is not based in any particular theoretical framework, but in both ordinary and technical theory-neutral concepts. In the last part of the paper, I argue that it follows from most accounts of the concept of mental disorder that the disciplines concerned with explaining some mental disorders are not branches of medicine, and that the treatment of some mental disorders is not a matter of medical intervention.

Work and its consequences in enterprise is studied. Family as an institution is the basical example of division of work, which is the situation where human being perfecionates himself. Perfection takes place working, as an integrating technique which has no limits.

In this article we are going to approach the question of the intersubjectivity. To understand why the intersubjectivity is a modern problem and which is the solution that it fits, we have chosen to follow a descending route that gives light and should illuminate what today, in many areas, is seen as a problem. We will begin, consequently, approaching the person as not identical but dual. The above mentioned cosideration takes us from the hand to the distinction between someone and (...) something that reveals the unlimited character of the person. The distinction indicates that what is own of the person is to coexist, that is to say, that there cannot be only one person. Thus, monism is incompatible with the personal being and, having reached the person as coexistence, the discoveries are extended on to intersubjectivity, proper of modern anthropology. (shrink)
