Expert skill in music performance involves an apparent paradox. On stage, expert musicians are required accurately to retrieve information that has been encoded over hours of practice. Yet they must also remain open to the demands of the ever-changing situational contingencies with which they are faced during performance. To further explore this apparent paradox and the way in which it is negotiated by expert musicians, this article profiles theories presented by Roger Chaffin, Hubert Dreyfus and Tony and Helga Noice. For (...) Chaffin, expert skill in music performance relies solely upon overarching mental representations, while, for Dreyfus, such representations are needed only by novices, while experts rely on a more embodied form of coping. Between Chaffin and Dreyfus sit the Noices, who argue that both overarching cognitive structures and embodied processes underlie expert skill. We then present the Applying Intelligence to the Reflexes (AIR) approach?a differently nuanced model of expert skill aligned with the integrative spirit of the Noices? research. The AIR approach suggests that musicians negotiate the apparent paradox of expert skill via a mindedness that allows flexibility of attention during music performance. We offer data from recent doctoral research conducted by the first author of this article to demonstrate at a practical level the usefulness of the AIR approach when attempting to understand the complexities of expert skill in music performance.

In elite sport, the advantages demonstrated by expert performers over novices are sometimes due in part to their superior physical fitness or to their greater technical precision in executing specialist motor skills. However at the very highest levels, all competitors typically share extraordinary physical capacities and have supremely well-honed techniques. Among the extra factors which can differentiate between the best performers, psychological skills are paramount. These range from the capacities to cope under pressure and to bounce back from setbacks, to (...) the knowledge of themselves, opponents, and the domain, which experts access and apply in performance. In the companion chapter on breadth and depth of knowledge in expert sport (see Chapter 11), we discussed the forms or kinds of knowledge deployed by elite athletes, and described some lines of research which seek to tap and study such expert knowledge (McPherson & MacMahon, 2008; McRobert, Ward, Eccles & Williams, 2011). In this chapter we focus more directly on questions about methods for measuring or more accurately assessing expert knowledge, in particular addressing a wider range of methods to help us understand what experts know. Suggesting that sport researchers can productively adopt and adapt existing qualitative methodologies for integration with more standard quantitative methods, we introduce and survey a number of areas of qualitative research in psychology.

The biochemistry of geotropism in plants and gravisensing in e.g. cyanobacteria or paramacia is still not well understood today [1]. Perhaps there are more ways than one for organisms to sense gravity. The two best known relatively old explanations for gravity sensing are sensing through the redistribution of cellular starch statoliths and sensing through redistribution of auxin. The starch containing statoliths in a gravity field produce pressure on the endoplasmic reticulum of the cell. This enables the cell to sense direction. (...) Alternatively, there is the redistribution of auxin under the action of gravity. This is known as the Cholodny-Went hypothesis [2], [3]. The latter redistribution coincides with a redistribution of electrical charge in the cell. With the present study the aim is to add a mathematical unified field explanation to gravisensing.

RésuméKarl Popper, dans La logique de la découverte scientifique, a généralisé et formalisé, sans le savoir, les grands principes méthodologiques formulés par Claude Bernard dans son Introduction àľétude de la médecine expérimentale.Cette analogie est frappante lorsqu'on rapproche du faillibilisme poppérien ľ affirmation du physiologiste selon laquelle les progrès de la méthode expérimentale consistent en ce que la somme des vérités augmente à mesure que la somme des erreurs diminue.Ľ intérêt que ľ on porte à cette analogie dépasse la simple curiositéérudite (...) car certaines difficultés du poppérianisme sont déjà sensibles dans la méthodologie bernardienne.En effet, si ľ un et ľ autre insistent sur le caractère hypothético‐déductif de la démarche scientifique, ni ľ un ni ľ autre n'aborde le difficile problème des décisions épistémiques qu'elle requiert. C'est notamment au niveau des hypothèses falsifiantes destinées àéviter les coïncidences constituent un des écueils les plus graves que rencontre la méthode expérimen‐tale qu'est sensible cette difficulté.SummaryIn his Logic of Scientific Discovery Karl Popper, nor realizing the fact, has generalized and formalized the main methodological principles formulated by Claude Bernard in his Introduction àľ Etude de la Médecine Expérimentale.This analogy is especially noticeable when one brings together Popper's “faillibilism” and the physiologist's affirmation according to which “progress in the experimental method consists in the fact that the more the total error decreases, the more the total truth increases”.The interest in this analogy goes far beyond erudite curiosity since some of Popper's difficulties are already perceptible in Bernard's methodology.As a matter of fact, if both stress the hypothetical‐deductive nature of the scientific progress, none approaches the difficult problem of the epistemic decisions required. This difficulty is particularly perceptible at the level of the falsifying hypotheses intended to avoid the “coincidences being one of the most serious pitfalls of the experimental method” .ZusammenfassungOhne es zu wissen, hat Karl Popper in der Logik der Forschung die methodischen Prinzipien, die Claude Bernard in seiner Introduction àľ Etude de la Médecine Experimental formuliert, verallgemeinert und formalisiert.Die Analogie tritt besonders deutlich hervor, wenn man Poppers Faillibilismus mit der Behauptung des Physiologen konfrontiert, wonach der Fortschritt darin bestehen soll, dass die Summe der Wahrheiten in dem Masse zunimmt, wie die Summe der Irrtümer abnimmt.Das Interesse an dieser Analogie ist insofern nicht ein rein historisches, als gewisse Schwie‐rigkeiten, denen Popper begegnet, sich schon in Bernards Ansatz bemerkbar machen.Wenn auch beide besonderes Gewicht auf den hypothetisch‐deduktiven Charakter des wis‐senschaftlichen Vorgehens legen, so gehen sie beide nicht auf das schwierige Problem der erkenntnistheoretischen Entscheide ein, diedamit verbunden sind. Dieser Mangel macht sich vor allem bei Poppers falsifizierenden Hypothesen bemerkbar, die, wie schon Bernard formuliert, dazu dienen sollen, die Hauptschwierigkeit der experimentellen Methode, namlich das zufällige Zusammentreffen von Ereignissen, zu vermeiden.

In a discussion-note in Mind, Father P. M. Farrell, O.P., gave an account, in what he admitted to be an embarrassingly brief compass, of the Thomist doctrine concerning evil. There is one sentence in this discussion which at first glance appears paradoxical. Father Farrell has been arguing that a universe containing ‘corruptible good’ as well as incorruptible is better than one containing ‘incorruptible good’ only. He continues: ‘If, however, they are to manifest this corruptible good, they must be corruptible and (...) they must sometimes corrupt.’ The final words, despite Father Farrell's italics, strike one as expressing, not a self-evident truth, but a non sequitur. The fact that I am capable of committing murder does not entail that I will at some time commit it. It is not immediately obvious that a similar entailment holds in the case of corruption and corruptibility. (shrink)

This collection of essays, addresses, and one interview come from the years 1966-73 and cover a wide spectrum of interest, dealing with such general topics as 'The Absence of God in Modern Culture' and 'The Future of Christianity.'.

The posterior parietal cortex (PPC) is the most likely site where egocentric spatial relationships are represented in the brain. PPC cells receive visual, auditory, somaesthetic, and vestibular sensory inputs; oculomotor, head, limb, and body motor signals; and strong motivational projections from the limbic system. Their discharge increases not only when an animal moves towards a sensory target, but also when it directs its attention to it. PPC lesions have the opposite effect: sensory inattention and neglect. The PPC does not seem (...) to contain a “map” of the location of objects in space but a distributed neural network for transforming one set of sensory vectors into other sensory reference frames or into various motor coordinate systems. Which set of transformation rules is used probably depends on attention, which selectively enhances the synapses needed for making a particular sensory comparison or aiming a particular movement.

For countable structure, "Scott rank" provides a measure of internal, model-theoretic complexity. For a computable structure, the Scott rank is at most [Formula: see text]. There are familiar examples of computable structures of various computable ranks, and there is an old example of rank [Formula: see text]. In the present paper, we show that there is a computable structure of Scott rank [Formula: see text]. We give two different constructions. The first starts with an arithmetical example due to Makkai, and (...) codes it into a computable structure. The second re-works Makkai's construction, incorporating an idea of Sacks. (shrink)

Christian physicians are in danger of losing the right of conscientious objection in situations they deem immoral. The erosion of this right is bolstered by the doctrine of "physician value neutrality" (PVN) which may be an impetus for the push to require physicians to refer for procedures they find immoral. It is only a small step from referral to compelling performance of these same procedures. If no one particular value is more morally correct than any other (a foundational PVN premise) (...) and a physician ought to be value neutral, than conscientious objection to morally objectionable actions becomes a thing of the past. However, the argument for PVN fails. Therefore, Christian physicians should state their values openly, which would allow patients the ability to choose like-minded physicians. Some possible responses to this erosion of conscientious objection include, disengagement from non-Christian institutions, the formation of distinctly Christian medical institutions and political action. However, for the Christian the initial focus should be on a life of holiness which requires each of us to avoid evil. (shrink)

In this paper the authors argue that ethical considerations are relevant for evaluating animal production systems and that in consequence agrologists should seriously consider the arguments of animal welfare supporters. Furthermore, the authors point out the ethical basis for some (though not all) of the conclusions proposed by supporters of animal welfare. In consequence it is necessary to determine the nature of animal welfare and methods of evaluating the welfare of animals and to recognize when production systems fail to satisfy (...) the needs of animals.

We study reducts of Peano arithmetic for which conditions of saturation imply the corresponding conditions for the whole model. It is shown that very weak reducts (like pure order) have such a property for κ-saturation in every κ ≥ ω 1 . In contrast, other reducts do the job for ω and not for $\kappa > \omega_1$ . This solves negatively a conjecture of Chang.

Roman Catholic moral theology follows a centuries-old tradition of moral reflection. Contemporary Roman Catholic moral theory applies these traditional arguments to the realm of medical ethics, including the issues of active euthanasia and physician-assisted suicide. Unavoidable moral limits on licit medical intervention sometimes require that the moral duty to treat, cede to the duty to cease treatment when measures become more harmful than beneficial to the patient. This does not reduce the need for the compassionate use of palliative care in (...) response to suffering. However, it does mean that rather than being excessively committed to maintaining mere biological human life, or actively seeking death, that we learn a sober realism about the limits of human life. Catholic moral analysis examines an act objectively, both in its relation to the agent and as a material event in the world. This allows both the virtuous or vicious intentions of the agent and the effects of the action to be included in its moral evaluation. Thus, Catholic moral analysis is both quasi-deontological and quasi-consequentialist. Objectively, active euthanasia and physician-assisted suicide, as acts of deliberate killing, are seen as repugnant, in that they fail to incarnate a benign inner intention or to form an agent in virtue. Catholic moral theology is extremely skeptical that an act of intending death directly can be consonant with a sincere compassion for the dying, suffering person and views it as a direct negation of the precious gift of human life.

In the modal literature various notions of completeness have been studied for normal modal logics. Four of these are defined here, viz. (plain) completeness, first-order completeness, canonicity and possession of the finite model property — and their connections are studied. Up to one important exception, all possible inclusion relations are either proved or disproved. Hopefully, this helps to establish some order in the jungle of concepts concerning modal logics. In the course of the exposition, the interesting properties of first-order definability (...) and preservation under ultrafilter extensions are introduced and studied as well. (shrink)

Is it possible to interfere with individual decision-making while preserving freedom of choice? The purpose of this article is to assess whether ‘libertarian paternalism’, a set of political and ethical principles derived from the observations of behavioural sciences, can form the basis of a viable framework for the ethical analysis of public health interventions. First, the article situates libertarian libertarianism within the broader context of the law and economics movement. The main tenets of the approach are then presented and particular (...) attention is given to its operationalization through the notion of a ‘nudge’. Essentially, a ‘nudge’ consists in an intervention, which aims to suggest one choice over another by gently steering individual choices in welfare-enhancing directions yet without imposing any significant limit on available choices. Finally, the article concludes that, while it fails as an overreaching framework of ethical analysis, libertarian paternalism nonetheless constitutes a valuable addition to the conceptual toolbox of public health ethics.

There has been no generally accepted cognitive definition of dreaming. An electrophysiologic correlate (REM sleep) has become its defining characteristic. Dreaming and REM sleep are complex states for which the Dreaming + REMs model is over-simplified and limited. The target articles in this BBS special issue present strong evidence for a dissociation between dreaming and REM sleep. [Hobson et al.; Nielsen, Revonsuo; Solms; Vertes & Eastman].

In this paper, we state a metatheorem for constructions involving coding. Using the metatheorem, we obtain results on coding a family of sets into a family of relations, or into a single relation. For a concrete example, we show that the set of limit points in a recursive ordering of type ω 2 can have arbitrary 2-REA degree.
