The question of what explains individual differences in expertise within complex domains such as music, games, sports, science, and medicine is currently a major topic of interest in a diverse range of fields, including psychology, education, and sports science, to name just a few. Ericsson and colleagues’ deliberate practice view is highly influential perspective in the literature on expertise and expert performance—but is it viable as a testable scientific theory? Here, reviewing more than 25 years of Ericsson and colleagues’ writings, (...) we document critical inconsistencies in the definition of deliberate practice, along with apparent shifts in the standard for evidence concerning deliberate practice. We also consider the impact of these issues on progress in the field of expertise, focusing on the empirical testability and falsifiability of the deliberate practice view. We then discuss a multifactorial perspective on expertise, and how open science practices can accelerate progress in research guided by this perspective. (shrink)

P. Ia. Chaadaev continues to attract the attention of researchers of Russian thought. Some recent publications in our press justify the assertion that scholars are interested not only in this or that side of the views of "the philosopher of Basmannaia Street" but also in the very character of his mentality and its place in the history of Russian philosophical thought. Thus, Viacheslav Vsevolodovich Ivanov writes in his article "Chaadaev-Our Contemporary" [Chaadaev-nash sovremennik] : "There are several reasons why Chaadaev is (...) not at home in Russia and in the history of Russian thought. One of them is his extreme rationalism and logical orientation. He is the follower of Western European rationalism, mainly, I think, of the French rationalist tradition. For him the chief achievement of civilization is the syllogism, the deduction of logical conclusions from some kind of premises and he takes history to be a unified whole." The same problem of Chaadaevan mentality is raised by P.V. Kuznetsov in his article "The Metaphysical Narcissus: P. Ia. Chaadaev and the Fate of Philosophy in Russia" [Metafizicheskii nartsiss. P. Ia. Chaadaev i sud'ba filosofii v Rossii] , which contrasts Chaadaev's thought with the Eastern "apophatic consciousness.". (shrink)

In a previous work [the second and the third author, “On paraconsistent deontic logic”, Philosophia 16, 293-303 (1986)] investigated certain systems of paraconsistent deontic in order to investigate the problem of contradiction in the domain of ethics. This paper continues this line of research, studying some paraconsistent systems containing alethic and deontic modalities. This approach allows us to treat the principles of Kant (OA→ \diamond A) and Hintikka (\square A → OA) from the classical and from the paraconsistent point of (...) view, and to propose systems in which either, both, or neither of these principles is valid.

This article presents empirical evidence to address how some visitors build relationships with a wildland place over time. Insights are drawn from qualitative interviews of recreation visitors to the backcountry at Rocky Mountain National Park in Colorado. The article describes relationship to place as the active construction and accumulation of place meanings. The analysis is organized around three themes that describe how people develop relationships to place: time and experience accrued in place, social and physical interactions in and with the (...) setting, and an active reflective process of regulating sense of identity to affirm commitment to place.

Let ƒ be a real number. It is well known [7] that the set of rational numbers which are less than ƒ is a recursive set if and only if ƒ is representable as the limit of a recursive, recursively convergent sequence of rational numbers. In this paper we replace the condition that the set of rational numbers less than ƒ is recursive by the condition that this set is at various points in the Kleene hierarchy, and we replace the (...) recursive, recursively convergent limit by a variety of other recursive limiting processes.

The purpose of this study is to examine the importance that real patients attach to their right to withdraw from an on-going feasibility randomised trial (RCT) evaluating types and timings of breast reconstruction (two parallel trials) following mastectomy for breast cancer. Our results show that, while some respondents appreciated that exercising the right to withdraw would defeat the scientific objective of the trial, some patients with a surgical preference consented only given the knowledge they could withdraw if they were not (...) allocated to their preferred treatment.

The purpose of the study is to identify a common theoretical basis for the study of human life as capital and unconditional higher value. Theoretical basis is based on the value-laden and revised structural constructivism, provided by the French philosopher and sociologist Pierre Bourdieu, critical analysis of the concepts of capital as the embodiment of social expectations, the biological concept of the value of human life, as well as the concepts of its sanctity. Originality. It is proved that one should (...) not consider the value of human life as capital only but instead takes into account its different value interpretations, especially when forming the social identity of a person. Moreover, in each of the value systems, the value of human life can be recognized as unconditional, which does not prevent the coexistence of such different value interpretations within the framework of one social identity, which then inevitably becomes a multiple social identity. Conclusions. Human life cannot be considered as a result of integrating economic expectations into the concept of "advertising" capital: first, expectations may well be inadequate; second, expectations by themselves are not directly related to capital; third, expectations do not necessarily lead to development; fourth, one should clearly distinguish between the spontaneous "expectations" and the values that express people’s strong motivation as members of social communities. The multiplicity of possible cultural conditions that affirm the unconditional value of life indicates that this unconditionality is always relevant rather than absolute. The multiple social identities could be used to add value to the protection of human life, the affirmation of multiple social identities is a means of affirming the unconditional value of human life – it is unconditional in several alternative ways.

If Unamuno had been able to choose how to be remembered, he would have wanted him to be a poet. This book wants to do justice to that happy possibility. But above all because Unamuno was a poet in the highest sense: he was while writing the same essay as a novel, or theater, letter or verse, and he was also a poet when he passionately lived all the facets of his intense existence. His intellectual work was poetic and his (...) personal relationships, as well as his political activity, also responded to that peculiar Unamunian aesthetic in which the vital horizon is inescapably confused with the tasks of thought." --Translated from back cover.
