Brouwer and Weyl recognized that the intuitive continuum requires a mathematical analysis of a kind that set theory is not able to provide. As an alternative, Brouwer introduced choice sequences. We first describe the features of the intuitive continuum that prompted this development, focusing in particular on the flow of internal time as described in Husserl's phenomenology. Then we look at choice sequences and their logic. Finally, we investigate the differences between Brouwer and Weyl, and argue that Weyl's conception of (...) choice sequences is defective on several counts. (shrink)

Cet article montre ce que la cooccurrence peut nous apprendre sur la monosémie et comment on peut exploiter l’analyse des cooccurrences de deuxième ordre pour quantifier l’analyse sémantique. Les analyses sont conduites sur un corpus technique (1,7 million d’occurrences) relevant du domaine spécialisé des machines-outils pour l’usinage des métaux. Dans cet article, nous expliquons la méthodologie adoptée pour déterminer le degré de monosémie d’un mot technique à partir de l’analyse du recoupement de ses cooccurrences de deuxième ordre. Dans le but (...) d’affiner les résultats de la mesure de recoupement, nous procédons également à quelques expérimentations qui vont au-delà du simple repérage statistique des cooccurrences et qui font varier différents paramètres, tels que la fenêtre d’observation, le seuil de significativité et la forme graphique ou le lemme des cooccurrences de premier et deuxième ordre. Finalement, nous abordons l’importance de l’intégration des étiquettes morphosyntaxiques dans l’analyse des cooccurrences. (shrink)

This article explores the relation between innovation and resources that are governed as commons by looking at the governance of potato genetic resources, especially in the context of the emergence ofhybrid diploid potato breedingthat will enable potato propagation through true seeds. As a new breeding tool, hybrid diploid potato breeding may not only revolutionize traditional potato breeding practices, it may also strongly affect current governance modes of potato genetic resources as a commons. Contrary to conventional accounts of the commons that (...) treat technological innovation mainly as an exogenous factor, we argue that technological innovation can better be understood as an endogenous factor. In particular, we develop aco-production frameworkof innovation and the commons that draws attention to the different ways in which innovation, commons and its governance interact. Using this framework, we demonstrate that the constitution of potato genetic resources as a commons cannot be understood without considering the various ways in which technological innovation affects resources and mediate how these are governed. While reversely, technological innovations themselves are also enabled and constrained by users who govern potato genetic resources as a shared resource. We argue that changes in the governance of genetic resources can be understood as a change from one socio-technical constellation to another, whereby innovations, resources, and institutions are continuously co-produced.

The related fields of fractal image encoding and fractal image analysis have blossomed in recent years. This book, originating from a NATO Advanced Study Institute held in 1995, presents work by leading researchers. It is developing the subjects at an introductory level, but it also has some recent and exciting results in both fields. The book contains a thorough discussion of fractal image compression and decompression, including both continuous and discrete formulations, vector space and hierarchical methods, and algorithmic optimizations. The (...) book also discusses multifractal approaches to image analysis, segmentation, and recognition, including medical applications. (shrink)

Aristotle asserts that philosophy, which begins in wonder, seeks principles and causes in the world, just as mythology does, but each in a different way. This article argues that Homer analyzes the world according to Vico’s imaginative genera; early Greek philosophy according to natural genera, and philosophers in the strict sense according to rational genera. Thus, Homer’s rainbow is the goddess Iris, which Xenophanes divides into natural object and divinity, and which Aristotle calls principles or causes. In the transition from (...) imaginative to natural genus, wonder is lost because the enchanted world of mythology has become explicable in terms of the five senses. Plato’s and Aristotle’s philosophical approach seeks to restore wonder without remythologizing the world. Homer’s Oceanus myth is examined, in relation to the testimony of Thales and the fragments of Xenophanes, and as reflected explicitly and implicitly in the works of Plato and Aristotle. (shrink)

Now that the Washington Football Team, formerly known as the Redskins, has succumbed to recent political pressure and changed its name, some may think that the fight over pseudo-Native-American representations (PNAR) in sports is over and won in favor of the activists. I will argue, using Beauvoir’s existential ethics, that PNAR in general is immoral and that several other teams should also change their branding.

This article focuses on how biblical content and spiritualities can be communicated, probably more effectively, to (late) preschool children by using information technology, which has already been implemented successfully for years in secular and religious environments. Because children enjoy listening to stories, watching cartoons and playing every day, the approach in this research will be to propose a particular construct to communicate biblical content to preschool children. This construct comprises interactive storytelling, cartoon animation and educational gaming, which constitute a trilogy (...) for teaching biblical content and principles to preschool children. This should be done interactively. These three approaches have become fundamental designs and presentations in child education. Churches, Christian nurseries and other Christian educators, in general, are encouraged to develop computer programs according to the construct and strategy proposed in this article for the teaching of the Gospel to late preschool children. The approach in this article will be, firstly, to examine and explore the religious orientation of preschool children and, secondly, to validate and propose how computer technology can be implemented to communicate the biblical content to preschool children via the trilogy of interactive storytelling, cartoon animation and educational gaming in an uninterrupted experience. Contribution: This article argues that the use of interactive storytelling, cartoon animation and educational gaming should be used consecutively and uninterruptedly to communicate the biblical message to preschool children. This is probably the most effective way to keep the attention of these children and to affect their conduct. (shrink)

Het verhaal van de natuurkunde is ook een persoonlijk verhaal, want achter de feiten gaan altijd mensen schuil. Van Einstein, die Beethoven op zijn viool probeert te spelen, tot Van Swinden, die jarenlang in het planetarium in Franeker werkt. Cees Andriesse, die 'Titan kan niet slapen' schreef, een biografie over Christiaan Huygens, heeft veel gevoel voor deze verhalen. In deze nieuwe geschiedenis van de natuurkunde wordt dan ook ruim aandacht besteed aan de zoektocht en wederwaardigheden van grote figuren, maar ook (...) van collega's uit de tijd dat Andriesse in Groningen werkte. De wetenschap draait om onmiskenbare relaties tussen harde feiten; die gaan spreken onder de pen van Andriesse, die oog heeft voor de ontdekkers en zichtbaar maakt hoe zijn eigen begrip is ontstaan. Het is hem niet te doen om de mechanisering van de natuurkunde, maar om de historisering daarvan. Dit boek biedt een nieuw perspectief op grote ontdekkingen, waarbij zowel God, als literatuur als psychologie een rol spelen. (shrink)

Whereas right-libertarians do not think that it is a requirement of justice that we raise revenues for persons with disabilities, both left-libertarians and liberal egalitarians think that there is such a requirement. An issue remains for the latter two theorists—how ought we to raise this revenue? Liberal egalitarians typically endorse either universal taxation or taxation of the wealthy. Left-libertarians, on the other hand, cannot so easily appeal to the methods of universal taxation and taxation of the wealthy, as they are (...) illegitimately coercive. One such method left open to the left-libertarian is one proposed by Michael Otsuka. He argues that both left-libertarians and liberal egalitarians should find the method of taxation of the unjust to be a reasonably strong way of raising revenue. In this paper, I point out problems with Otsuka’s argument, as well as directly criticize the method of taxation of the unjust. (shrink)

Our epistemic access to mathematical objects, like numbers, is mediated through our external representations of them, like numerals. Nevertheless, the role of formal notations and, in particular, of the internal structure of these notations has not received much attention in philosophy of mathematics and cognitive science. While systems of number words and of numerals are often treated alike, I argue that they have crucial structural differences, and that one has to understand how the external representation works in order to form (...) an advanced conception of numbers. The relation between external representations and mathematical cognition will be discussed by drawing on experimental results from cognitive science and mathematics education, and I argue for the constitutive role of external representations for the development of an advanced conception of numbers.

Jonathan Wolff is Professor of Philosophy at University College London. He is the author of Robert Nozick (1991), An Introduction to Political Philosophy (1996) and Why Read Marx Today (2002). He is currently working on a number of topics at the intersection of political philosophy and public policy.

Ethical thought experiments such as the trolley dilemma have been investigated extensively in the past, showing that humans act in utilitarian ways, trying to cause as little overall damage as possible. These trolley dilemmas have gained renewed attention over the past few years, especially due to the necessity of implementing moral decisions in autonomous driving vehicles. We conducted a set of experiments in which participants experienced modified trolley dilemmas as drivers in virtual reality environments. Participants had to make decisions between (...) driving in one of two lanes where different obstacles came into view. Eventually, the participants had to decide which of the objects they would crash into. Obstacles included a variety of human-like avatars of different ages and group sizes. Furthermore, the influence of sidewalks as potential safe harbors and a condition implicating self-sacrifice were tested. Results showed that participants, in general, decided in a utilitarian manner, sparing the highest number of avatars possible with a limited influence by the other variables. Derived from these findings, which are in line with the utilitarian approach in moral decision making, it will be argued for an obligatory ethics setting implemented in ADVs. (shrink)

In Miletus, about 550 B.C., together with our world-picture cosmology was born. This book tells the story. In Part One the reader is introduced in the archaic world-picture of a flat earth with the cupola of the celestial vault onto which the celestial bodies are attached. One of the subjects treated in that context is the riddle of the tilted celestial axis. This part also contains an extensive chapter on archaic astronomical instruments. Part Two shows how Anaximander (610-547 B.C.) blew (...) up this archaic world-picture and replaced it by a new one that is essentially still ours. He taught that the celestial bodies orbit at different distances and that the earth floats unsupported in space. This makes him the founding father of cosmology. Part Three discusses topics that completed the new picture described by Anaximander. Special attention is paid to the confrontation between Anaxagoras and Aristotle on the question whether the earth is flat or spherical, and on the battle between Aristotle and Heraclides Ponticus on the question whether the universe is finite or infinite.

Schleiermachers Wissenschaftslehre wird in dieser Untersuchung als eine universale Prinzipienlehre und formale Strukturtheorie rekonstruiert. Es werden mit einem interdisziplinären Ansatz im Anschluß an und in Weiterführung von Überlegungen Schleiermachers zur Struktur von Wirklichkeit und zu ihrer Erkenntnis grundlegende Fragen der Bildung und Konzeptualisierung von Wissenschaften im allgemeinen und von Theologie im besonderen behandelt. Über seine Platoninterpretation, die Rolle der Naturphilosophie, und eine Analyse zentraler Texte Schleiermachers wird erkennbar, daß sich hinter der dyadisch bestimmten Semantik de facto eine triadische Elementarstruktur verbirgt, (...) die über das Operieren mit Dualen zu generieren versucht wird und von der her allererst seine Theorieanlage und Systementscheidungen plausibel werden.

Servant leadership has been theorized as a model where the moral virtue of humility co-exists with action-driven behavior. This article provides an empirical study that tests how these two apparently paradoxical aspects of servant leadership interact in generating follower engagement, while considering the hierarchical power of the leader as a contingency variable. Through a three-way moderation model, a study was conducted based on a sample of 232 people working in a diverse range of companies. The first finding is that humble (...) leaders showed the highest impact on follower engagement regardless of their hierarchical position. Less humble leaders in lower hierarchical positions seem to be able to compensate for that through a strong action-oriented leadership style. Most notably for leaders in high hierarchical positions, the moral virtue of humility seems to strengthen the impact of their action-oriented leadership the most. These findings provide empirical support and a better understanding of the interplay between the moral virtue of humility and the action-oriented behaviors of servant leadership. (shrink)

People undergo many idiosyncratic experiences throughout their lives that may contribute to individual differences in the size and structure of their knowledge representations. Ultimately, these can have important implications for individuals' cognitive performance. We review evidence that suggests a relationship between individual experiences, the size and structure of semantic representations, as well as individual and age differences in cognitive performance. We conclude that the extent to which experience-dependent changes in semantic representations contribute to individual differences in cognitive aging remains unclear. (...) To help fill this gap, we outline an empirical agenda that utilizes network analysis and involves the concurrent assessment of large-scale semantic networks and cognitive performance in younger and older adults. We present preliminary data to establish the feasibility and limitations of such empirical, network-analytical approaches. (shrink)

ABSTRACT. The received picture of linguistic communication understands communication as the transmission of information from speaker's head to hearer's head. This picture is in conflict with the attractive Lewisian view of belief as self-location, which is motivated by de se attitudes – first-personal attitudes about oneself – as well as attitudes about subjective matters such as personal taste. In this paper, I provide a solution to the conflict that reconciles these views. I argue for an account of mental attitudes and (...) communication on which mental content and speech act content is understood as sets of multicentered worlds – roughly, possible worlds ‘centered’ on a sequence of individuals at a time. I develop a Stalnakerian model of communication based on multicentered worlds content, and I provide a suitable semantics for personal pronouns and predicates of personal taste. The resulting picture is one on which the point of conversation is the coordination of individual perspectives. (shrink)

During the last fifty years, the dialogue between science and religion in Germany has gained momentum. This essay briefly describes the academic setting in Germany with denominational theology at state universities and explains the development of secularization in reunified Germany. Twenty-five years after reunification, East Germany is one of the most secular societies in the world, and religion is seen as a strange relic. This poses challenges to the interaction between science and religion in both parts of Germany. The essay (...) then presents important institutions and contributors to the interaction between science and religion in Germany over the past fifty years, emphasizing the importance of private institutes at the intersection of the academy with society, churches, and ethical challenges.

This volume contains the proceedings of a conference on the Presocratic philosophers Pythagoras and Heraclitus. Investigated by a team of international scholars are key problems in doxography, Pythagorean Communities, logos, harmony, psychology, flux, number theory, ethics, and theology. Designed for all students of ancient philosophy, this volume will spur further investigations into these cardinal concerns of early Greek scientific thinkers.

In the context of some criticism about social responsibility education in business schools, the paper reports findings from a survey of CSR education (teaching and research) in Europe. It analyses the extent of CSR education, the different ways in which it is defined and the levels at which it is taught. The paper provides an account of the efforts that are being made to mainstream CSR teaching and of the teaching methods deployed. It considers drivers of CSR courses, particularly the (...) historical role of motivated individuals and the anticipation of future success being dependent on more institutional drivers. Finally it considers main developments in CSR research both by business school faculty and PhD students, tomorrow''s researchers and the resources devoted to CSR research. The conclusion includes questions that arise and further research directions. (shrink)
