The security of the civil aviation network is closely related to flight safety. Security situation prediction is the advanced stage of situational awareness in the civil aviation network. In this article, a prediction approach of security situations for the air traffic management network is proposed on the basis of the wavelet neural network. The proposed approach adopts the wavelet theory and neural network, combining a time-series forecasting method for the prediction of security situations in the civil aviation network. The experimental (...) results show that this approach has the advantages of fast training and high prediction accuracy. (shrink)

Economics is a culturally and politically powerful and contested discipline, and it has been that way as long as it has existed. For some commentators, economics is the "queen of the social sciences", while others view it as a "dismal science" (and both of these epithets allow for diverse interpretations; see Mäki 2002). Economics is also a discipline that deals with a dynamically complex subject matter and has a tradition of reducing this complexity by using systematic procedures of simplification. Nowadays, (...) these procedures involve for the most part building and using mathematical models (for an overview of the philosophical issues, see Morgan and Knuuttila 2011). In the dominant circles of the discipline, one is not regarded as a serious economist having a professional expert view on any given economic or social issue without having a model about it. Much of the power of the discipline and its characteristic contestations therefore involve models and modelling: the successes and failures of the dismal queen are those of modeling. The issues involved in conomic modeling have been made particularly acute once again by the financial crisis of 2008-2009 and its aftermath: the discipline of economics is among the candidates for the major blame for failure. I will first outline some thoughts about the characteristics disciplinary conventions that guide and constrain modeling in economics. I will then summarize my account of the very ideas of models and modeling. Finally, within the framework of that account, I will highlight some major issues of contestation and sketch the respective notions of potential success and failure in economic modeling with illustrations. These notions are motivated by my subscription to a (flexible and discipline-sensitive) realist philosophy of science (e.g. Mäki 2005). (shrink)

In seiner Aufsatzsammlung Anthropologie statt Metaphysik behandelt Ernst Tugendhat große metaphysische Fragen mit nüchternem Blick auf uns Menschen. Tugendhat plädiert dort an mehreren Stellen für ein erkenntnistheoretisches Prinzip, nach dem wir uns z.B. dann zu richten haben, wenn wir uns fragen, ob wir an Gott glauben sollen. Das Prinzip lautet: Wenn die rationalen Gründe zugunsten einer Überzeugung genauso stark sind wie die rationalen Gegengründe, und wenn wir – unabhängig von Vernunft – das Bedürfnis verspüren oder den Wunsch oder die Hoffnung, (...) dass die Überzeugung wahr sein möge, dann sollen wir uns gegen die fragliche Überzeugung entscheiden. Ich halte dies Prinzip für zu pessimistisch und für überzogen rational. Meiner Ansicht nach wären wir nicht gut beraten, dem Prinzip in unserem geistigen Leben immer zu folgen; das ist nur in ganz speziellen Fällen ratsam. Um das plausibel zu machen, gehe ich verschiedene Alltagsbeispiele durch, bei denen das Prinzip greifen würde und bei denen sich seine Anwendung so ähnlich anfühlt wie bei der Frage nach Gott. Die Beispiele betreffen Fragen der künstlerischen Selbsteinschätzung, des Wetters, der Liebe sowie der menschlichen Qualitäten von Vor- und Nachfahren. Und da Tugendhats Prinzip schon bei solchen harmlosen Beispielen pessimistische, aber keineswegs zuverlässige Ratschläge erteilt, sollten wir es besser auch nicht auf die Frage nach Gott anwenden.

Recent controversy about the use of the vertebrate fossil record for external calibration of molecular clocks centers on two issues, the number of dates used for calibration and the reliability of the fossil calibration date. Viewing matters from a palaeontological perspective, we propose three qualitative, phylogenetic criteria that can be used within a comparative framework for the selection of well-constrained calibration dates from the vertebrate fossil record. On the basis of these criteria, we identify three highly suitable new fossil calibration (...) dates for molecular clock estimates: the lungfish–tetrapod split (between 419 and 408 Ma), the bird–crocodile split (between 251 and 243 Ma), and the alligator–caiman split (between 71 and 66 Ma). Together with our previously suggested bird–lizard split (between 252 and 257 Ma), these four fossil dates span a range of very different ages. They are, in our opinion, more suitable for molecular clock calibration than the traditionally used mammal–bird split, which is less well constrained. We plea for closer interactions between paleontologists and molecular biologists in studying the timescale of vertebrate evolution. BioEssays 27:1069–1075, 2005. © 2005 Wiley Periodicals, Inc.

Este artículo examina el desarrollo histórico y la jurisdicción del "inspector de la policía y del mercado" (sahib al-surta wa-l-suq) en Córdoba a través de los casos judiciales tomados de la colección de dictámenes jurídicos de Ibn Sahl al-Ahkam al-Kubrà y de fuentes biográficas e históricas. Durante el período de Taifas, esta expresión omeya dio paso al "inspector de sentencias jurídicas" (sahib al-ahkam). A través de más de veinte casos, datables entre los años 456 / 1064 y 464 / 1072, (...) se demuestra cómo este juez, que no era qadi, seguía en sus sentencias el fiqh malikí, tanto en las leyes procesales como en la ley sustantiva.

Este artigo trata da formação moral do homem segundo Kant. Para ele, “o homem, afetado por tantas inclinações, é na verdade capaz de conceber a idéia de uma razão pura prática, mas não é tão facilmente dotado da força necessária para a tornar eficaz in concreto no seu comportamento”. Deste modo, para implementar nossas máximas de comportamento Kant elabora seu estudo sobre a formação do homem para levá-lo a uma vida livre e moral.

Afin de saisir la portée du débat nord-américain sur les communautarismes pour l’éthique théologique chrétienne actuelle, il paraît nécessaire de faire le point sur la différence entre le communautarisme des traditions intellectuelles, morales et spirituelles partagées, ou communautarisme éthico-religieux et éthico-politique, et le communautarisme politique. Le second, pour autant qu’il postule l’existence de communautés séparées au sein du politique, en est selon nous réduit à échouer comme modèle politique, aussi bien en ce qui concerne la démocratie à l’intérieur des Etats-nations (...) qu’en ce qui touche les relations entre Etats-nations . D. Müller prête ici attention à la valeur herméneutique constructive des traditions intellectuelles, morales et ou spirituelles, et plaide pour la fécondité partielle d’une telle approche lorsqu’il est question de construire une éthique théologique à visée vraiment universelle.To understand the scope of the North American debate on the communitarianisms for Christian theological ethics today, it seems necessary to discuss the difference between the communitarism of shared intellectual, moral and spiritual traditions or ethical-religious and ethical-political communitarianism, and political communitarianism. The latter, insofar as it postulates the existence of separate communities within the political sphere is, in our view, bound to fail as a political model, both as regards democracy inside nation-states , and as regards relations between nation-states . D. Müller is calling attention here to the constructive hermeneutic value of intellectual, moral and spiritual traditions and arguing in favor of the partial fecundity of such an approach when it is a question of constructing a theological ethic with a truly universal outlook.

Institution caractéristique d'une Cappadoce peu urbanisée, les chorévêques (ou ' évêques des campagnes ') sont attestés pour l'essentiel aux IVe et Ve siècles. C'est leur place dans le gouvernement de l'Église nouvellement impériale que nous avons examinée pour montrer que, loin de témoigner d'une première évangélisation et prise en charge par l'Église de ces communautés rurales d'Asie Mineure, leur importance au IVe siècle, puis leur effacement au siècle suivant signalent en fait la mise sous tutelle de ces mêmes communautés et (...) de leur organisation ecclésiastique par la hiérarchie épiscopale, conformément au principe d'accommodement. Cette conclusion invalide l'idée, encore récemment énoncée, que les campagnes dans leur ensemble ont été christianisées tardivement, et postérieurement aux cités. (shrink)

Platão tem uma visão negativa da arte e da tragédia. A “irracionalidade” da prática artística está na base dessa negação. Sua visão é contrária ao perspectivismo humanista de Eurípedes e dos sofistas. Na filosofia renascentista, o sujeito observador (temporal e racional) pressupõe o múltiplo e o infinito. O perspectivismo está na base dessa orientação e Shakespeare é a melhor expressão artística desse pressuposto defendido na filosofia por Giordano Bruno.

Pinjás Sadé fue considerado un heterodoxo en el seno de la “Cultura Estatal” israelí que constituyó su entorno vital. En la primera parte de este artículo presento su biografía y su obra más representativa, La vida como parábola, publicada en 1958, así como sus raíces románticas y frankistas y su inclinación hacia el cristianismo de acuerdo con el Evangelio. En la segunda parte se hace un análisis mítico de esa obra según la estructura del viaje interior del héroe en busca (...) del sentido de su vida. Presento la metodología seguida, basada en los trabajos del Círculo de Eranos . Analizo después los mitemas encontrados en la obra. Finalmente, comparo esos mitemas con los que aparecen en la obra Siddharta de Hermann Hesse. (shrink)

Las fuentes históricas ofrecen un material nada despreciable sobre fenómenos meteorológicos y astronómicos y el Rawḍ al-qirṭās de Ibn Abī Zar‛ es un buen ejemplo de ello. En el artículo se transcribe el texto árabe de acuerdo con la edición de Rabat 1976, a continuación se ofrece la traducción de Huici Miranda y por último se comenta la noticia. Una vez verificados los datos que aporta la obra relativos a eclipses y «cometas » sobresalen dos fenómenos: el primero y más (...) significativo es la observación de la supernova del año 1006 AD. Esta misma noticia ofrece la novedad, dentro de la tradición astronómica árabe, de que el autor atribuya, basándose en las observaciones de los antiguos, un carácter cíclico a los cometas. El segundo evento destacable es la aurora boreal observada, posiblemente, en Córdoba en el siglo IX. Finalmente, la datación exacta de los eclipses permite corregir algunas fechas erróneas del texto árabe cuyos manuscritos difieren bastante entre sí. (shrink)

Die vorliegende Studie beleuchtet die Problematik der Unbeherrschtheit im gesamten Corpus Platonicum und rekonstruiert die historisch nachweisbare Differenz zwischen Sokrates und Platon in diesem Punkt anhand des Leib-Seele-Verhältnisses. Unter Rekurs auf Xenophons Memorabilia wird gezeigt, dass das sokratische Verständnis von akrasia subkutan auf einem rigorosen Leib-Seele-Dualismus unter Annahme einer eingestaltigen Seele beruht. Bei Platon verschieben sich diese Koordinaten: In Politeia IV wird der Konflikt im Rahmen der seelischen Trichotomie internalisiert, während im Spätwerk der Leib zwar wieder als unmittelbarer ursächlicher Faktor (...) für unbeherrschtes Verhalten auftritt, aber nicht mehr in dualistischer Entgegensetzung zur Seele verstanden wird. Insofern Platon vom evaluativen Monismus der sokratischen Handlungspsychologie abrückt, ist bei ihm eine relativ „starke" Form von Willensschwäche möglich, die sich nicht einfach auf Unwissenheit im Sinne kognitiver Fehlleistungen reduzieren lässt. Die Entwicklungen in Sachen akrasia innerhalb des Corpus Platonicum gehen somit insgesamt mit der Revision des Verhältnisses von Leib und Seele einher. (shrink)

Cet article s’adosse au travail d’un centre d’action médico-social précoce qui prend en charge des enfants dont les parents viennent d’un ailleurs. Face aux retards de développement présentés par les enfants accompagnés, l’institution médico-sociale et les familles peuvent avoir des lectures différentes sur ce qui se passe pour l’enfant. Le recours à l’approche transculturelle permet aux familles d’assurer une double protection de leur enfant, en adhérant aux soins médicaux et psychologiques proposés par l’institution et en mobilisant leurs ressources familiales, culturelles (...) et parfois religieuses à travers des rituels de soins, chacune des deux méthodes ayant pour objectif d’assurer un apaisement de l’enfant et la bonne poursuite de son développement.

Deism, which is known for denying the belief in prophethood and the hereafter while accepting the existence of a deity who is understood through reason but does not interfere with the universe while, has gained increasing popularity especially in positive scientific circles in Europe with the Enlightenment period. The development of deism in Europe has been significantly influenced by the ideas of philosophers and scientists such as Descartes, Newton, Voltaire, David Hume, and Kant. Although there is no word in Islamic (...) terminology that corresponds with the meaning of deism, terms such as Dahriyya, Barāhima, ilhad and heresy have been used to refer to different types of denial, including deism and atheism. However, it can be said that “Dahriyyah” is closer to atheism in meaning, while “Barāhima” is used in a more specific sense to deny prophethood. The words “ilhad” and heresy are used to express any kind of denial that rejects the principles of Islam. Parallel to deism being a subject of interest in our country and around the world, there has been a significant increase in studies conducted both in favour and against it. In this article, the rational proofs mentioned by Māturīdī regarding the existence of the hereafter, which deism rejects, have been discussed. In particular, the evidence found in the exegesis of relevant verses of the Qur’ān in Kitab al-Ta’wilat have been subject to examination. Māturīdī has emphasized the importance of providing rational proof for those who do not believe in the Qur’ān, stating that they will not accept any evidence derived from it. Māturīdī, who researched the reasons why people deny the afterlife, explained that people’s attempt to understand everything by comparing them to their own abilities is an important reason for the denial of the afterlife. According to him, people deny the afterlife because they believe that the power to resurrect the dead is beyond their own abilities and assume that their power is not enough for such an act. If they had contemplated the creation of the heavens and the earth, they would have realised that Allāh’s power is different from the power of His creatures. Furthermore, Imam Māturīdī pointed out that it would be absurd and pointless for Allāh, the Creator of the universe, to have created it solely for the purpose of its destruction. He emphasised that there must be a purpose for its creation, and that this purpose indicates the existence of the afterlife, where the actions of the created beings will be accounted for. In addition, Māturīdī, who said “If the world was eternal, it would not be possible to repay the deeds done,” emphasised the necessity of distinguishing between virtuous and evil individuals and giving everyone the reward or punishment they deserve. He acknowledged that human beings live in this world as a test, and the true consequences of their actions will be revealed in the hereafter. (shrink)

The promise and the threat (al-wa’d wa al-wa‘īd) issue, which has been debated among theological sects, is primarily related to the problem of grave sin. This critical issue discussed in the framework of the problem of grave sin and in the context of the faith-action relationship has been shaped based on the definitions of faith of the emerging sects. Through examining the Qur’ān verses about al-wa’d and al-wa‘īd, answers to such questions whether the Qur’ān verses about to indicate generality (‘umūm) (...) or specification (khusūs) and whether divine promise and threat can change have been sought. In the beginning, the disputations occurring between Murji’ah and Mu‘tazilah, afterward, have become one of the essential matters of debate among Māturīdīs and the Mu‘tazilī scholars. Even though Imām Māturīdī expresses common criticisms against Khawārij and Mu‘tazilah, he mainly condemns the Mu‘tazilī doctrine. Mu‘tazilah treats the principle in question based on the idea that, by force of divine justice, it is necessary for God to reward the faithful and punish the disobedient. According to them, because a grave sin that is not repented requires to stay permanently in the hell, intercession (shafā‘ah) is not possible for such a person. However, Māturīdī argues that a claim of this kind cannot be valid from the point of justice by emphasizing that faith, which is a state of constant assent, prevents the punishment. In this essay, Māturīdī’s criticisms have been discussed with regard to directly related issues such as justice, grave sin, and intercession. (shrink)

Époque de transition, la Renaissance connaît une série d’évolutions de l’idée politique d’empire (héritée du Moyen Âge) vers la réalité moderne d’un vaste marché coordonnant progressivement les économies nationales particulières et leurs réseaux d’influence. Ces évolutions permettent-elles d’évoquer la mise en place d’une « version économique de l’empire » ? Peut-on regarder ce qui se joue à la Renaissance, saisie à travers ses relations géopolitiques, comme la préfiguration de la globalisation ? L’article examine ces questions à partir de plusieurs hypothèses (...) et défend la thèse que l’idée d’empire subit à cette époque des « métamorphoses », c’est-à-dire des évolutions qui en modifient le concept, notamment en ce qui concerne le rapport entre domination et territorialité.

After briefly introducing the notion of mask within Nietzsche’s philosophy, as well as its connection with the idea of every possible ‘identity’, we aim at analyzing the position held by Zarathustra’s mask as a teacher, in line with the meanings of his ‘teachings’. We’ll show how Zarathustra’s teaching presents as a sort of nonteaching, thereby indicating how it becomes itself visible amongst some problems in contemporary thought.

Against attempts to vacate silence of the possibility of expression, and empty the expression of its own silence, this article proposes as a task for our contemporary world that we should be silence-trackers. This task is not easy, since the decisive silence cannot be heard, but it is treasured within the words and works as their last and most inspired truth. To that end, it is taken as a guide the famous Letter of Lord Chandos (Hofmannsthal), who claims his silence-in-transit (...) (exceeded by a new experience of the overwhelming richness of reality), as well as Blanchot’s reflections on the relationship between silence and inspiration. In the second part, the article “tracks”, as “exemplary” examples, the silences of A. López (Dream of Light) and the one involved in the secret of “Rosebud” (Citizen Kane, Welles).Keywords: silence, inspiration, expression, Chandos, Hofmannsthal, Blanchot. (shrink)

Ele investiga, primeiramente, a origem dos argumentos de Hartshorne, partindo de uma interpretação de Anselmo; em segundo lugar, o argumento lógico-modal é apresentado, junto com as suas pressuposições e implicações. Finalmente, o autor propõe uma avaliação da abordagem de Hartshorne.

Cet article traite de l'activité complexe de raisonnement quand les gens, au sens ethnométhodologique du terme, « fabriquent » la société et les institutions sociales. Traditionnellement, l'étude du raisonnementet de la connaissance humaine a reposé sur des hypothèses qui sont en désaccord avec la prise en compte de la nature socioculturelle et sociocognitive des activités collectives. Notre raisonnement dans ses grandes lignes est que une analyse de l'usage in situ de catégories institutionnelles révèlent des liens intimes entre la pensée, la (...) communication et des outils matériels. Les artéfacts physiques constituent des externalisations de la connaissance; nous nous reportons sur des objets des représentations avec lesquelles nous agissons plus tard. Dans le dispositif utilisé ici pour mesurer, écrire et documenter les évènements et les activités, les catégories pour coder le monde apparaissent sous forme textuelle et sont utilisées comme procédés de construction de sens et de coordination de divers systèmes d'activité. La capacité des catégories à être des liens qui relient connaissance, communication et technologie est illustrée ici par des exemples empiriques de pratiques de conseil pour la recherche d'emploi dans une agence spécialisée.This article focuses on the complex activity of reasoning, when people - as the ethnomethodologists put it - "make" society and social institutions. Traditionally the study of human reasoning and cognition has been based on assumptions which are at odds with recognising the sociocultural and sociocognitive nature of collective activities. The outline of our argument is that an analysis of the in situ use of institutional categories, points to very close links between thinking, communication and material tools. Physical artefacts represent externalisations of human knowledge; we project representational signs onto objects and we later inter-act with those signs. In our systems used for measuring, writing, and documenting events and activities, categories for codifying the world appear in textual form, and they are used as sense making and co-ordinating devices in various activity systems. The capacity of categories as boundary objects that bridge cognition, communication, and technology is illustrated by empirical examples from vocational guidance practices at a public employment office.

During the Renaissance, as an age of transition, the political idea of empire (a legacy of the Middle Ages) is subject to a series of evolutions leading to the modern reality of a large market, gradually coordinating national economies and their influence networks. Do these evolutions allow us to speak of an « economical version of the empire »? Can we view this process, described through the geopolitical relationships of the Renaissance, as a prefiguration of modern globalization? This paper deals (...) with these questions from various points of view, in order to prove that the Renaissance idea of empire undergoes « metamorphosis », or evolutions, which modify its concept, regarding notably the relationship between domination and territoriality.
