We propose a model mechanism for the initiation and spatial positioning of teeth primordia in the alligator, Alligator mississippiensis. Detailed embryological studies by Westergaard and Ferguson have shown that jaw growth plays a crucial role in the developmental patterning of the tooth initiation process. Based on biological data we develop a dynamic patterning mechanism, which crucially includes domain growth. The mechanism can reproduce the spatial pattern development of the first seven teeth primordia in each half jaw of A. mississippiensis. (...) The results for the precise spatio-temporal sequence compare well with experiment. Simulation of the model also predicts that certain transplantations can alter the spatial sequence of teeth primordia initiation. (shrink)

Appearing in English for the first time, Schelling’s 1842 lectures develop the idea that many philosophical concepts are born of religious-mythological notions.

Pure Type Systems, PTSs, were introduced as a generalization of the type systems of Barendregt's lambda cube and were designed to provide a foundation for actual proof assistants which will verify proofs. Systems of illative combinatory logic or lambda calculus, ICLs, were introduced by Curry and Church as a foundation for logic and mathematics. In an earlier paper we considered two changes to the rules of the PTSs which made these rules more like ICL rules. This led to four kinds (...) of PTSs. Most importantly PTSs are about statements of the form M:A, where M is a term and A a type. In ICLs there are no explicit types and the statements are terms. In this paper we show that for each of the four forms of PTS there is an equivalent form of ICL, sometimes if certain conditions hold. (shrink)

This article discusses the role of moment-to-moment affect dynamics in mental disorder and aims to integrate recent literature on this topic in the context of complex dynamical system theory. First, we will review the relevance of temporal and contextual aspects of affect dynamics in relation to psychopathology. Related to this, we will discuss recent insights resulting from a network view on affect dynamics in psychopathology. Next, we explore how we can reconcile literature findings from a perspective of complex dynamical system (...) theory. Finally, future directions with regard to personalized assessment of risk and diagnostic use are discussed. (shrink)

People who work and live in a certain moral practice usually possess a specific form of moral wisdom. If we manage to incorporate their moral intuitions in ethical reasoning, we can arrive at judgements and theories that grasp a moral experience that generally cannot be found outside the said practice. To achieve this goal, we need a legitimate way to balance moral intuitions, ethical principles and general theories. In the present contribution, we describe a version of the model of Reflective (...) Equilibrium, which we call the Normative-Empirical Reflective Equilibrium . RE provides a framework for ethical thinking that includes both moral experience and normative theory.After an outline of the model, we focus on the role of empirical research and illustrate how empirical data on moral intuitions can add to the comprehensiveness of the set of moral beliefs in NE-RE. Subsequently, we describe how coherence among the elements of an NE-RE can be understood and measured. Finally, we address an important question for any method of moral reasoning: what is the status of the outcome of the reasoning process? This is a matter of justification. We argue for a so-called good reasoning-justified outcome strategy in NE-RE. This strategy is built on a reasoning process in which the reason-giving force of each element is tested and weighed. The thinker has to work towards a coherent view in which only the elements with sufficient justificatory power are retained. If the thinker decides that the elements fit together into a coherent view, a reflective equilibrium is reached. NE-RE is an attempt to describe a model for moral reasoning that can profit from the moral wisdom present among experienced agents through the use of empirical research. (shrink)

Ben Saunders claims that actual consent is not necessary for organ donation due to ‘normative consent’, a concept he borrows from David Estlund. Combining normative consent with Peter Singer's ‘greater moral evil principle’, Saunders argues that it is immoral for an individual to refuse consent to donate his or her organs. If a presumed consent policy were thus adopted, it would be morally legitimate to remove organs from individuals whose wishes concerning donation are not known. This paper disputes Saunders' arguments. (...) First, if death caused by the absence of organ transplant is the operational premise, then, there is nothing of comparable moral precedence under which a person is not obligated to donate. Saunders' use of Singer's principle produces a duty to donate in almost all circumstances. However, this premise is based on a flawed interpretation of cause and effect between organ availability and death. Second, given growing moral and scientific agreement that the organ donors in heart-beating and non-heart-beating procurement protocols are not dead when their organs are surgically removed, it is not at all clear that people have a duty to consent to their lives being taken for their organs. Third, Saunders' claim that there can be good reasons for refusing consent clashes with his claim that there is a moral obligation for everyone to donate their organs. Saunders' argument is more consistent with a conclusion of ‘mandatory consent’. Finally, it is argued that Saunders' policy, if put into place, would be totalitarian in scope and would therefore be inconsistent with the freedom required for a democratic society. (shrink)

In modern approaches to phonology a lack of clarity exists on the issue of whether phonetic facts are psychological or physical realities. The results from an experiment suggest that phonetic facts can be considered as psychological realities, but with the restriction that they can take acoustical shape. More specifically, the syntactic material consisted of ambiguous French sentences of the following sort: On a tourné ce film intéressant pour les étudiants. They were spoken in disambiguating contexts, without the readers noticing the (...) ambiguities, and without context, but with the instruction to make a conscious effort to disambiguate. By tape splicing, the contexts were removed from the context-embedded sentences. Twenty-eight native speakers of French listened to the sentences and judged whether one or the other meaning had been intended by the speaker. Subjects performed significantly above chance: 60% correct identifications for context-embedded sentences, 75% for context-free sentences. Pitch-amplitude analyses were made to determine the acoustical differences involved. (shrink)

Medical councils increasingly require graduates to understand law and to practise medicine mindful of the legal rules. In the UK a revised curriculum for medical law and ethics has been published. However, coverage of law in medical education remains variable and doubts exist about how far students acquire legal knowledge and skills in its implementation. This survey of students in two UK medical schools measured their law learning and their confidence in using this knowledge. Concept maps and a self-audit questionnaire (...) were used to capture students' understanding and perceptions of this knowledge domain and self-assessments of their legal knowledge and skills. A large sample was achieved across first, second and final year students. Students agree that a sound understanding of law is essential to being a good doctor. Their perceptions of law are generally positive but the interface between the legal rules and codes of medical ethics creates difficulty. In some areas students offer relatively confident self-assessments of their legal knowledge and skills for practising law. However, levels of confidence in other areas of their law learning raise doubts about the degree to which they can advocate for and protect their patients. Conclusions are drawn about the effectiveness of students' law learning and recommendations made for further research. (shrink)

An authorized, eminently readable translation of a work first published in German in 1957. Martin leads his reader into the problems of metaphysics by tracing the development of Plato's thought and Aristotle's criticism of Plato, focusing throughout on the question, "What is unity?" Although the book is introductory in intent and tone, it offers its own interpretation of Plato and Aristotle.--J. M. W.

This eighth volume of the Collected Works of Jung comprises a collection of essays in which Jung struggles with the basic theoretical problems of his psychology. He brings an impressive erudition to his search for concepts, models and explanatory principles adequate to the refractory psychic phenomena with which he deals. In keeping with Jung's conviction that the psyche is "a thing of such infinite complexity that it can be observed and studied from a great many sides," the essays exhibit a (...) variety of approaches, from the relatively empirical to the frankly speculative. The essays span some forty years of Jung's reflection and, thanks to their arrangement in thematic groupings by the editors, present an interesting study in the refinement of his thought and statement.--J.

The static properties of leaves with parallel venation from terrestrial orchids of the genus Epipactis were modelled as coupled elastic rods using the geometrically exact Cosserat theory and the resulting boundary-value problem was solved numerically using a method from Shampine, Muir and Xu. The response of the leaf structure to the applied force was obtained from preliminary measurements. These measurements allowed the Young’s modulus of the Epipactis leaves to be determined. The appearance of wrinkles and undulation characteristics for some leaves (...) has been attributed to the small torsional stiffness of the leaf edges. (shrink)

The primary aim of this study was to investigate the relation between self-perceived executive functions and the school achievement of young adolescents, while controlling for parental education and sex. We specifically focused on executive aspects of daily life behavior and the higher-order EFs, as measured with self-report, rather than on the more basic EFs which have been the primary focus of prior investigations. In two independent samples of sixth graders, students evaluated their EFs on a self-report questionnaire, the Amsterdam Executive (...) Functioning Inventory. School achievement in the domains of mathematics and reading comprehension were evaluated with nationally used, norm-based achievement tests. Results revealed that the self-perceived EFs of young adolescents were significantly correlated with their school achievement in both study samples. School achievement was also correlated with the level of parental education, but the factor sex did not have such influence. In study 1, self-perceived EFs explained additional variance in school achievement, while controlling for parental education and sex. In study 2, this was only the case for the most robust measure of school achievement, i.e., the end-of-primary-school final achievement test. Furthermore, besides the relation with achievement tests, we also found a relation between self-perceived EFs and teacher ratings behavioral problems in the classroom. Together, our findings imply that young students can properly reflect on the effectiveness and appropriateness of their EFs in a way that is relevant to their academic achievement and classroom behavior. The findings underscore the importance of considering the development of EFs and parental education in the evaluation of academic achievements in early adolescence. (shrink)

Dicke discusses the metamorphosis of Hegelianism in Feuerbach and Marx through an examination of the concept of identity in the three philosophers. He demonstrates the persistence of this concept as a decisive theme in both Feuerbach and Marx, and shows how Hegel's doctrine of identity is transformed and adulterated in the process of adaptation. A primary consequence of Marx's modification of this doctrine is the philosophical sacrifice of the individual to the collective, which has its practical consequences in contemporary communist (...) states.--J.

The author regards faith as a restless quest for that which can save man from his self-destructive tendencies and allow him to actualize most completely his constructive potentialities. Wieman critically examines several answers to this quest of faith, including those of Dewey, Tillich, and Barth. In contrast he develops the view of "liberal religion," which finds the answer in a divine creativity fostered by communication, and is productive of fresh insights which transform human ideals.--J. M. W.

A thoughtful Christian counter-offensive on the popular interpretation of Marxism as the absolute antithesis of all that is Christian and democratic. The author's explicit intention is to break down the barrier to understanding and communication constituted by that image. He examines the Judeo-Christian heritage of Marxism and traces the influences which led to Marx's estrangement from that heritage. Elements of the heritage which survived the estrangement are then elucidated and the author concludes with an eminently reasonable appraisal of the legitimate (...) points of contact and conflict between the two doctrines.--J.

Combining an appreciation of recent analyses of "types" of scientific explanation with a detailed knowledge of contemporary biological investigations, Goudge examines the theory of evolution since Darwin. He argues that twentieth century evolutionary theory gives rise to philosophical questions whose importance rivals anything that physics has to offer. After showing how "modern selectionist theory" differs from Darwin's view of evolution, he asks: "Has evolutionary theory metaphysical implications?" The answer--a tentative "yes"--is so carefully qualified that one wonders whether new contributions to (...) the theory of evolution have the philosophic import that Goudge claims for them.--J. M. W.
