We evaluated the relationships of daily sleep duration and inconsistency with soft tennis competitive performance among 15 healthy collegiate soft tennis players. Sleep duration and inconsistency were determined by a 50-day sleep diary, which recorded sleep and wake times of sleep. Soft tennis athletic performance was evaluated by a service and baseline stroke accuracy test and the spider run test. Mean sleep duration was 7.4 ± 1.7 h. No correlation was found between long-term mean sleep duration and athletic performance. But (...) inconsistency in sleep duration was inversely correlated with service score after controlling for soft tennis experience and sex. There was no significant relationship between sleep inconsistency and other athletic performance. This result indicates that reducing the instability of sleep duration in the long-term may have a positive effect on soft tennis players’ service performance. Although participants’ current mean sleep duration was not as sufficient as the recommendation in sleep extension experiments, it revealed the importance for athletes to maintain regular sleep in daily life.

Nous nous proposons dans cette intervention de structurer synchroniquement trois moments philosophiques d’origines differentes : l’intuition agissante chez Kitarō Nishida, la dialectique de la mediation absolue chez Hajime Tanabe et la philosophie de l’individuation chez Gilbert Simondon, dans un contexte de reflexion philosophique sur la nature de la vie humaine. Les trois moments semblent susceptibles de se croiser, se critiquer et se completer dans un terrain transductif au sens ou l’entend Simondon. C’est ce nouveau terrain que nous entendons defricher afin (...) d’ouvrir une perspective ou un individu humain se transforme en agent responsable d’un transhumanisme a travers le processus de l’individuation dynamique et transindividuelle, laquelle nous preparerait a l’emergence du posthumain dans un futur proche.

Dans la double conception du sujet que précise Tokieda Motoki dans sa théorie du processus langagier : sujet subordonné au prédicat et sujet d’action langagière volontaire, conception fondée sur une théorie linguistique inspirée principalement d’études grammaticales de la langue japonaise et qui s’est donc totalement émancipée du paradigme de la grammaire des langues européennes, on peut retrouver, de manière tout à fait paradoxale et frappante, le sens originaire du sujet, à savoir celui de son origine latine « subjectum » qui (...) est d’ailleurs la traduction du mot grec « ὑποκείμενον », à double titre : celui qui est assujetti ou soumis à une instance supérieure ou plus fondamentale et celui qui est susceptible de donner lieu ou occasion aux accidents, aux faits contingents.

We show that length initial submodels of S12 can be extended to a model of weak second order arithmetic. As a corollary we show that the theory of length induction for polynomially bounded second order existential formulae cannot define the function division.

We define a theory of two-sort bounded arithmetic whose provably total functions are exactly those in ${\mathcal{F}_{LOGCFL}}$ by way of a generalized quantifier that expresses computations of SAC 1 circuits. The proof depends on Kolokolova’s conditions for the connection between the provable capture in two-sort theories and descriptive complexity.

師廣松哲学の「体系の軋み」を見た熊野が若きヘーゲル哲学に寄港し彷徨い、ついには「父殺し」に辿り着いたことを鮮やかに描出。同時に、廣松哲学体系の破綻を浮き彫りにする黒田晩年の静謐なる論断。.

We define a fragment of Primitive Recursive Arithmetic by replacing the defining axioms for primitive recursive functions by those for functions in some specific complexity class. In this note we consider such theory for AC0. We present a model-theoretical property of this theory, by means of which we are able to characterize its provably total functions. Next we consider the problem of how strong the induction scheme can be in this theory.

We will give a two-sort system which axiomatizes winning strategies for the combinatorial game Node Kayles. It is shown that our system captures alternating polynomial time reasonings in the sense that the provably total functions of the theory corresponds to those computable in APTIME. We will also show that our system is equivalently axiomatized by Sprague–Grundy theorem which states that any Node Kayles position is provably equivalent to some NIM heap.

I identify three functions of language: the communicative, the objectifying, and the objective. I claim that of these three functions, the objective function is the most essential, in the sense specified in the paper, and the communicative the least. I further indicate that language use without the communicative function is more prevalent than might commonly be believed.
