Existen dos versiones del instrumento astronómico conocido como al-sarrāŷiyya (siglo XIV). El artículo estudia la versión simple a partir de la edición y la traducción del manuscrito Cairo, Dār al-kutub, mīqāt, 291, analiza cómo y cuándo se recomienda su uso y comenta su relación con la azafea šakkāziyya del astrónomo andalusí Azarquiel (siglo XI).

Precautionary Principles are often said to be appropriate for decision-making in contexts of uncertainty such as climate policy. Contexts of uncertainty are contrasted to contexts of risk depending on whether we have probabilities or not. Against this view, I argue that the risk-uncertainty distinction is practically irrelevant. I start by noting that the history of the distinction between risk and uncertainty is more varied than is sometimes assumed. In order to examine the distinction, I unpack the idea of having probabilities, (...) in particular by distinguishing three interpretations of probability: objective, epistemic, and subjective probability. I then claim that if we are concerned with whether we have probabilities at all—regardless of how low their epistemic credentials are—then we almost always have probabilities for policy-making. The reason is that subjective and epistemic probability are the relevant interpretations of probability and we almost always have subjective and epistemic probabilities. In contrast, if we are only concerned with probabilities that have sufficiently high epistemic credentials, then we obviously do not always have probabilities. Climate policy, for example, would then be a case of decision-making under uncertainty. But, so I argue, we should not dismiss probabilities with low epistemic credentials. Rather, when they are the best available probabilities our decision principles should make use of them. And, since they are almost always available, the risk-uncertainty distinction remains irrelevant. (shrink)

The causal theory of action is widely recognized in the literature of the philosophy of action as the "standard story" of human action and agency -- the nearest approximation in the field to a theoretical orthodoxy. This volume brings together leading figures working in action theory today to discuss issues relating to the CTA and its applications, which range from experimental philosophy to moral psychology. Some of the contributors defend the theory while others criticize it; some draw from historical sources (...) while others focus on recent developments; some rely on the tools of analytic philosophy while others cite the latest empirical research on human action. All agree, however, on the centrality of the CTA in the philosophy of action. The contributors first consider metaphysical issues, then reasons-explanations of action, and, finally, new directions for thinking about the CTA. They discuss such topics as the tenability of some alternatives to the CTA; basic causal deviance; the etiology of action ; teleologism and anticausalism; and the compatibility of the CTA with theories of embodied cognition. Two contributors engage in an exchange of views on intentional omissions that stretches over four essays, directly responding to each other in their follow-up essays. As the action -oriented perspective becomes more influential in philosophy of mind and philosophy of cognitive science, this volume offers a long-needed debate over foundational issues.

Managers often ask why their firm should have an ethics program, especially if no one has complained about unethical behavior. The pursuit of business ethics can cost money, they say. It can lose sales to less scrupulous competitors and can drain management time and energy. But as Harvard business professor Francis Aguilar points out, ethics scandals (such as over Beech-Nut's erzatz "apple juice" or Sears's padded car repair bills) can severely damage a firm, with punishing legal penalties, bad publicity, (...) and irreparably injured customer relations. Equally important if less obvious, unethical behavior can undermine a firm's organizational spirit. On the other hand, Aguilar argues, in a well run firm, ethical programs can actually enhance corporate performance, strengthening the company at every level and supercharging employee risk taking and innovation. In Managing Corporate Ethics, Aguilar shows managers how to create ethical programs within their organizations that not only discourage large-scale wrongdoing, but can contribute substantially to the achievement of corporate excellence. Aguilar's program is down-to-earth and comprehensive, and based on his extensive research on highly successful, ethical companies, both large and small. He recommends action on three fronts: first, get senior management to provide effective ethical leadership; second, set up an ethics program that promotes concern for the interests of people affected by the firm's operations and that provides safeguards against corrupting business pressures; and third, staff the company with ethical people and surround the organization with ethical advisors (including legal, financial, accounting, tax, and marketing consultants). To illuminate this three-step program, Aguilar incorporates the lessons learned in his in-depth study of ten prominent firms with proven successful ethics programs--among them Hewlett-Packard, Johnson & Johnson, Nucor Steel, Cray Research, ServiceMaster, and Texas Instruments. He examines Lincoln Electric's attention to compensation and job security to ensure quality products and to reduce the pressure or temptation to act unethically. He shows how General Mills, while pushing product line managers to compete aggressively, uses corporate staff units to guard against illegal or unacceptable claims (testing cake recipes, for example, to see if a product's quality fails under the less-than-perfect conditions of a normal kitchen). And he details how Armstrong World Industries uses pep talks, inspirational stories, role models, and ready access to management to promote ethical standards among employees. Throughout, Aguilar demonstrates convincingly that an ethical program pays dividends: that employees, suppliers, customers, and the community at large know when they are being treated in a positive and constructive manner, and are likely to respond in kind. Packed with real life examples of successful (and failed) ethical programs, Managing Corporate Ethics is a valuable roadmap to an often overlooked source of business success. (shrink)

El presente artículo pretende acercarse a la propuesta de una concepción republicana de la ética empresarial realizada por la Escuela de Erlangen que se ha convertido en una referencia ineludible a nivel europeo. Esta propuesta, fundamentada en el constructivismo de la Escuela de Erlangen y la ética del discurso de la Escuela de Frankfurt, empezó a fraguarse a finales de los años ochenta en Alemania y define a la empresa como una institución con responsabilidades y deberes públicos. Con este artículo (...) se pretende mostrar una concepción de la ética empresarial sólida y coherente, tanto desde el punto de vista teórico como práctico, dada su capacidad de integrar las exigencias éticas con los aspectos organizativos, su proximidad a la praxis y su sistematicidad. The main purpose of this paper is to present the proposals of the Erlangen School for a republican conception of business ethics, which has become a key reference in the European context. Republican business ethics, based on the constructivism of the Erlangen School and the discourse ethics of the Frankfurt School, began to take shape at the end of the eighties in Germany and defines the company as "an institution with public responsibilities and duties". Throughout this article I will attempt to present a solid and coherent conception of business ethics, from both the theoretical and the practical points of view. Republican business ethics is capable of integrating ethical claims with organizational aspects, it comes close to praxis and it is systematic. (shrink)

Plantar un árbol dónde se necesita es un acto solidario. Investigar las características del bosque y las causas de su degradación, es una actividad de aprendizaje. Comprometerse en una campaña de reforestación aplicando y aprovechando lo estudiado, es aprendizaje-servicio.

El objetivo de este artículo es analizar las aportaciones que los avances en neuroética tienen en la toma de decisiones en las empresas. Empezaremos por cuestionar el paradigma dominante de la toma de decisiones empresariales desde el análisis crítico de los presupuestos epistemológicos de la teoría económica liberal, así como desde las perspectivas de las ciencias cognitivas y sus aportaciones al análisis del comportamiento humano. Continuaremos presentando dos grandes modelos de toma de decisiones éticas que se basan en la creación (...) de sentido intuitivo y que tienen sus fundamentos en los avances de las neurociencias. Concluiremos con breves observaciones críticas. (shrink)

Une boîte à outils théoriques pour les luttes sociales Il n’est pas facile de rendre compte d’un ouvrage comme celui-ci. En effet, derrière un titre qui peut sembler un peu anodin, Henri-Jacques Stiker propose un comprimé très dense de pensée contemporaine. Il puise dans de très nombreuses disciplines – philosophie, sociologie, sémiologie, anthropologie – et se réfère à une liste d’auteurs qui peut donner le vertige, de Leibniz à de Beauvoir, de Hume à Preciado, de Canguilhem à Butler, et de...

El presente ensayo analiza la obra de Augusto de Campos y su relación con la poesía visual. A partir del uso que hace el poeta brasileño de la página en negro para componer sus poemas, se propone una lectura de su obra en relación con el legado de Mallarmé y su idea de la escritura. Posteriormente, a partir de la idea de la materialidad de la lengua poética que está en el centro del proyecto poético de Augusto de Campos, se (...) plantea el pasaje hacia una dimensión háptica que se produce en sus poemas, sobre todo en “Anticéu” (“Anticielo”) de 1984.

The link between justice and climate change is becoming increasingly prominent in public debates on climate policy. This clear and concise philosophical introduction to climate justice addresses the hot topic of climate change as a moral challenge. Using engaging everyday examples the authors address the core arguments by providing a comprehensive and balanced overview of this heated debate, enabling students and practitioners to think critically about the subject area and to promote discussion on questions such as: Why do anything in (...) the face of climate change? How much do we owe our descendants – a better world, or nothing at all? How should we distribute the burden of climate action between industrialized and developing countries? Should I adopt a green lifestyle even if no one else makes an effort? Which means of reducing emissions are permissible? Should we put hope in technological solutions? Should we re-design democratic institutions for more effective climate policy? With chapter summaries, illustrative examples and suggestions for further reading, this book is an ideal introduction for students in political philosophy, applied ethics and environmental ethics, as well as for practitioners working on one of the most urgent issues of our time.

La nueva era de exploración espacial ha sopesado una y otra vez las posibilidades que tiene nuestro planeta de ser el lugar cósmico en el que las únicas formas de vida inteligentes del universo se hayan desarrollado. La astrofísica y la astrobiología lo ha hecho con números. Esta inquietud existencial se ha plasmado en una serie de escalas científicas que miden la importancia relativa del posible impacto sobre nuestra civilización de un encuentro con vida extraterrestre inteligente. Lamentablemente las consecuencias medidas (...) se han limitado a factores científicos y un hipotético control de daños, y a la credibilidad para con estos por parte de la opinión pública. Han olvidado sin embargo su trascendencia antropológica, moral y filosófica para nuestra especie. (shrink)

Social science research, whether observational or interventional, is confronted with situations where the dignity of participants and respect for cultural practices can be seriously affected. The aim of this article is twofold. Firstly, we will reflect on the ethical challenges facing social science research with special consideration of research in contexts of vulnerability. Secondly, we will propose the Kantian sense of respect as a normative framework to guide social science research.

In this work, we focus on the problem of selecting low-level heuristics in a hyperheuristic approach with offline learning, for the solution of instances of different problem domains. The objective is to improve the performance of the offline hyperheuristic approach, identifying equivalence classes in a set of instances of different problems and selecting the best performing heuristics in each of them. A methodology is proposed as the first step of a set of instances of all problems, and the generic characteristics (...) of each instance and the performance of the heuristics in each one of them are considered to define the vectors of characteristics and make a grouping of classes. Metalearning with statistical tests is used to select the heuristics for each class. Finally, we used the Naive Bayes to test the set instances with k-fold cross-validation, and we compared all results statistically with the best-known values. In this research, the methodology was tested by applying it to the problems of capacitated vehicle routing and graph coloring. The experimental results show that the proposed methodology can improve the performance of the offline hyperheuristic approach, correctly identifying the classes of instances and applying the appropriate heuristics in each case. This is based on the statistical comparison of the results obtained with those of the state of the art of each instance. (shrink)

This article takes a linguistic perspective of argumentation, as proposed by Marion Carel and Oswald Ducrot with the “Théorie des blocs sémantiques” (SBT: Semantic Block Theory). This theory argues that the meaning of a linguistic entity is determined by a collection of discourses that this entity calls to mind. Describing the meaning of a word, a syntagm or an utterance amounts to specifying the argumentative linkages (“enchaînements argumentatifs”) allowed by these entities. We propose a semantic and argumentative analysis of syntagms (...) mujer fácil , femme facile [easy woman] and hombre fácil , homme facile [easy man] that, in Romance languages in particular, hold different meanings: both hombre fácil/homme facile describe a man’s character or nature, whereas mujer fácil/femme facile, in their most common usage, imply a certain sexual behavior. We will compare the argumentative linkages that make up the meaning of mujer fácil/femme facile with those of other expressions that are part of the same semantic block. Also, this analysis will connect the proposed description to certain proverbial discourse about women, and it will call attention to the role that these expressions can play in a persuasive strategy.

Through the analysis of the thought of Mach and Duhem, who have felt the need to re-evaluate the relationship between metaphysics and physics, we study in what measure the authors had a position relating to an eventual weakening of the traditional epistemic criteria, which were until their time used for the evaluation of scientific theories, and those criteria should respect the distinction between fact and value. We investigate the way each argues for a division between science and metaphysics, as well (...) as the reasons for this. For both authors, adopting mechanicism as the basis for modern science is in the origin of the emergence of the materialist metaphysics, which should now be abandoned. Every metaphysics built from physical results would be a disrespect to the distinction between fact and value. Duhem and Mach argue for a new role for the common sense, which should not be taken as the source of error anymore. (shrink)
