This study evaluated the effects of an exergame program combined with traditional tennis training on autonomic regulation, tennis technique, gross motor skills, clinical reaction time, and cognitive inhibitory control in children. Sixty-three children were randomized into four groups and compared at baseline, 6-month immediately post intervention and at 1-year follow-up post intervention. At 6-month post intervention the combined exergame and regular training sessions revealed: higher breathing frequency, heart rate and lower skin conductance levels during exergaming; additional benefits in the point (...) of contact and kinetic chain elements of the tennis forehand and backhand technique ; negative impact on the shot preparation and the follow-through elements ; higher ball skills ; higher percentages of clinical reaction time improvement and cognitive inhibitory control improvement in both congruent and incongruent trials. The 1-year follow-up test showed no differences in the tennis technique, clinical reaction time and cognitive inhibitory control improvement between groups with the same number of trainings per week. The findings support exergaming as an additional training tool, aimed to improve important cognitive-motor tennis skills by adding dynamics to the standardized training process. Caution should be placed to planning this training, e.g., in a mesocycle, since exergaming might decrease the improvement of specific tennis technique parts of the trainees.. (shrink)

Nous ne pouvons pas laisser l'avenir de l'humanité et les questions écologiques à l'appréciation de quelques-uns. Ce problème mérite un véritable débat scientifique, philosophique et politique. Au milieu des incertitudes grandissantes, cet ouvrage se propose comme une lecture critique d'une culture dominée par la raison technoscientifique et la puissance capitaliste. Si l'humanité doit continuer à exister, comme le pense Hans Jonas, comment la vulnérabilité peut-elle devenir une force, un levier pour sa préservation? Le devoir-être des générations futures implique un devoir-agir (...) urgent de la part des générations actuelles. Lorsque cette exigence est menacée, la responsabilité s'impose comme un devoir de type kantien. L'humanité doit redécouvrir un nouveau rapport au monde : elle doit reconnaître que la nature est limitée et qu'elle n'est pas disponible à volonté. L'amour de la nature, la sobriété, la justice semblent incontournables dans l'exercice de cet impératif: 'Agis de façon que les effets de ton action soient compatibles avec la permanence d'une vie authentiquement humaine sur terre'"--Page 4 of cover.

Prispevek obravnava nekatere pojme politične filozofije Clauda Leforta. Pokazati želi, da za rekonstrukcijo politične filozofije, ki se je loteva Lefort, ni toliko konstitutiven njen prelom z znanstvenim diskurzom, ampak vse prej pojem simbolnega, ime za družbeno, ki je zavezano razliki in delitvi.

The objective of the present essay is to show that the traditional dilemma of philosophy, namely, does science think or does not think, has today become the problem that science itself has to solve. To assert that science thinks means first that science, when it thinks, constructs its object in an always specific manner; second, in construing its object, it adds to it the real, i.e., a reference, external to the scientific construction itself, which science then discovers as the basis (...) and source of its construction. This article argues that it is for strictly scientific reasons that science is today faced with the task of affirming itself as a domain of thought in both aforementioned meanings. Affirming the view that science thinks is a scientific struggle for the existence of politics of emancipation. (shrink)

Der Beitrag geht, sich auf die Grundlegung zur Metaphysik der Sitten und die Kritik der praktischen Vernunft beziehend, der Frage nach, ob es möglich ist, Kants praktische Philosophie, jenseits des Dilemmas abstrakter moralischer Universalismus vs. Rechte des Partikulären als Ansatz einer Theorie des subjektivierten Handelns zu begreifen. Das heisst eines Handelns, in dem das Individuum nicht nur im "Dienste der Güter" bzw. seiner empirisch-pathologischen Interessen und Neigungen steht. In der Beantwortung dieser Frage wird die Aussage des kategorischen Imperativs "ich soll (...) so oder so handeln, ob ich gleich nichts anderes wollte" im ersten Schritt als eine Forderung verstanden, die nicht einfach nichts Empirisches zu wollen verlangt, sondern das Wollen an ein Nichts als Etwas bindet. Im zweiten Schritt wird dann gezeigt, dass am Ort dieses Nichts als Etwas das Vernunftfaktum als abgründiger Grund eines Handelns steht, das mit dem Anspruch auftritt, für niemanden zu gelten, wenn es nicht bedingungslos für alle geltend gemacht werden kann.

A partir la thèse avancée par Monique David-Ménard, selon laquelle l’entendement réussi là où la raison échoue, il s’agit d’examiner la révolution kantienne dans la manière de penser. Pour tirer les conséquences du renversement dans la pensée mis en oeuvre par la philosophie kantienne, l’auteur interroge la constitution de la réalité dans la perspective transcendantale comme double opération avec le non-savoir portant respectivement sur le sujet et le noumène. Sur le fond de cette interrogation, il montre que la réalité à (...) laquelle a affaire la philosophie kantienne n’est ni la réalité objective constituée, ni la réalité hallucinée du désir de la raison transgressant les limites de la connaissance, mais à une réalité subjectivée, constituée par la mise en scène de la double destitution : celle de la réalité phénoménale et celle de la raison. C’est sur ce point que peut s’établir une alliance militante entre la philosophie et la psychanalyse, alliance dont l’enjeu principal, pour l’une comme pour l’autre, consiste justement en ceci que chacune, pour son propre compte, pense la réalité comme une telle scène du Deux.

Članek utemeljuje trditev, da za transcendentalno teorijo objektivnosti nista značilni le občost in nujnost, ampak tudi refleksivnost. Teorija objektivnosti se vselej tudi že obrača nazaj nase in določa pomen lastne določitve objektivnega spoznanja. Samonanašalnost spoznavne konstitucije objekta pa se izraža v nujnosti zveze med realnim nasprotjem in dialektičnim nasprotjem. Skozi to razmerje spoznanje ni le določeno kot objektivno, ampak je vselej tudi že naddoločeno kot uspeh. Pomen konstitucije spoznavnega objekta je uspeh, analiza Kantove fasciniranosti z nevarno bližino uma in norosti (...) pa pokaže, da misli njegova filozofija uspeh kot dejanje, s katerim se uspe um razmejiti od lastne norosti.

This article aims at clarifying the status of the Idea in two of Badiou's recent works: Second manifeste pour la philosophie and L'hypothèse communiste. Badiou sets out from the assumption that the operation with the Idea implies an affirmation of the materialism of a philosophy that is under the conditon of four generic procedures. In his attempt to elaborate Badiou's materialism of the Idea, the author does not turn to Plato, as one would expect, but, rather, to Kant's theory of (...) ideas such as it is presented in the Transcendental Dialectics of the first Critique. In so doing, the author seeks to develop Kant's idea in terms of the act. Posing the question of the Idea in terms of the act has at least two advantages: it shows how the pure reason separates itself from the Thing in itself that affects it while allowing for its appearance in the world.

Analysing the role of Kant’s third and final Critique, the _Critique of Judgement_, in the system of Kant’s three Critiques (_Critique of Pure Reason_, _Critique of Practical Reason_, _Critique of Judgement_), the paper posits that with the conclusion of the system of critiques in the third _Critique_, Kant succeeds in presenting it as a point of a transfinitisation of knowledge within the critiques’ system.

Rado’s Conjecture is a compactness/reflection principle that says any nonspecial tree of height ω1 has a nonspecial subtree of size ℵ1. Though incompatible with Martin’s Axiom, Rado’s Conjecture turns out to have many interesting consequences that are also implied by certain forcing axioms. In this paper, we obtain consistency results concerning Rado’s Conjecture and its Baire version. In particular, we show that a fragment of PFA, which is the forcing axiom for Baire Indestructibly Proper forcings, is compatible (...) with the Baire Rado’s Conjecture. As a corollary, the Baire Rado’s Conjecture does not imply Rado’s Conjecture. Then we discuss the strength and limitations of the Baire Rado’s Conjecture regarding its interaction with stationary reflection principles and some families of weak square principles. Finally, we investigate the influence of Rado’s Conjecture on some polarized partition relations. (shrink)

We prove that Rado's Conjecture implies that the nonstationary ideal on ω 1 is presaturated.

Todorčević showed that Rado's Conjecture implies CC*, a strengthening of Chang's Conjecture. We generalize this by showing that also CC**, a global version of CC*, follows from RC. As a corollary we obtain that RC implies Semistationary Reflection and, i.e. the statement that all forcings that preserve the stationarity of subsets of ω1 are semiproper.

A version of the Erdös-Rado theorem on partitions of the unordered n-tuples from uncountable sets is proved, without using the axiom of choice. The case with exponent 1 is just the Sierpinski-Hartogs' result that $\aleph (\alpha)\leq 2^{2^{2^{\alpha}}}$.

This is a continuation of our paper where we show that Rado's Conjecture can trivialize ‐sequences in some cases when ϑ is not necessarily a successor cardinal.

We show that both Rado's Conjecture and strong Chang's Conjecture imply that there are no special ℵ2-Aronszajn trees if the Continuum Hypothesis fails. We give similar result for trees of higher heights and we also investigate the influence of Rado's Conjecture on square sequences.

Let κ be a cardinal which is measurable after generically adding ${\beth_{\kappa+\omega}}$ many Cohen subsets to κ and let ${\mathcal G= ( \kappa,E )}$ be the κ-Rado graph. We prove, for 2 ≤ m < ω, that there is a finite value ${r_m^+}$ such that the set [κ] m can be partitioned into classes ${\langle{C_i:i (...) ${\mathcal G}$ in ${\mathcal G}$ such that ${[\mathcal{G} ^\ast ] ^m\cap C_i}$ is monochromatic. It follows that ${\mathcal{G}\rightarrow (\mathcal{G} ) ^m_{<\kappa/r_m^+}}$ , that is, for any coloring of ${[ \mathcal {G} ] ^m}$ with fewer than κ colors there is a copy ${\mathcal{G} ^{\prime}}$ of ${\mathcal{G}}$ such that ${[\mathcal{G} ^{\prime} ] ^{m}}$ has at most ${r_m^+}$ colors. On the other hand, we show that there are colorings of ${\mathcal{G}}$ such that if ${\mathcal{G} ^{\prime}}$ is any copy of ${\mathcal{G}}$ then ${C_i\cap [\mathcal{G} ^{\prime} ] ^m\not=\emptyset}$ for all ${i 2 we have ${r_m^+ > r_m}$ where r m is the corresponding number of types for the countable Rado graph.

Let ⪯R be the preorder of embeddability between countable linear orders colored with elements of Rado's partial order . We show that ⪯R has fairly high complexity with respect to Borel reducibility , although its exact classification remains open.
