Despite the known positive effects of acute exercise on cognition, the effects of a competitive team sport match are unknown. In a randomized crossover design, 20 female and 17 male field hockey players completed a battery of cognitive tests prior to, at half-time, and immediately following a competitive match ; with effect sizes presented as raw ES from mixed effect models. Blood samples were collected prior to and following the match and control trial, and analyzed for adrenaline, noradrenaline, brain (...) derived neurotrophic factor, cathepsin B, and cortisol. The match improved response times for a simple perception task at full-time and response times on the complex executive function task improved at half-time. Working memory declined at full-time on the match. The change in working memory was negatively correlated with increases in cortisol, as was the change in simple perception response time and the change in noradrenaline concentration. This study is the first to highlight the effects a competitive hockey match can have on cognition. These findings have implications for performance optimization, as understanding the influence on specific cognitive domains across a match allows for the investigation into strategies to improve these aspects.

"The Laws", Plato's most lengthy dialogue, has longbeen regarded as the most comprehensive explanation of the possible consequences of a practical application of his philosophy.We might expect the first question Plato ponders to be "What is Law?" Instead, the question posed is "Who is given the credit for laying down your laws?"We are privy to an interaction between a powerfulstatesman and an Athenian philosopher on theisland of Crete. We watch as a plan for a new political order is worked out (...) that embodiesmany of the issues that we still struggle withtoday, such as the status of women, the statusof homosexuals, the family, criminal law, andthe role of religion in a healthy society.We at Timeless Classic Books hope that you enjoy this ancient thought-provoking story that may change the way you think about modern day issues.(Timeless Classic Books).

Woodger's substitution of the "allegedly more precise term 'an environmentally insensitive set of lives'" for the term 'an inborn character' is discussed by haldane. He proposes that "woodger's definitions do not appear to have reached precision." (staff).

The thesis that there can be vague objects is the thesis that there can be identity statements which are indeterminate in truth-value (i.e., neither true nor false) as a result of vagueness (as opposed, e.g., to reference-failure), "the singular terms of which do not have their references fixed by vague descriptive means". (if this is "not" what is meant by the thesis that there can be vague objects, it is not clear what "is" meant by it.) the possibility of vague (...) objects should not be taken, in itself, to imply the more radical thesis that the identity relation can be one of "degree". one can hold that the concept of degrees of identity is absurd (how can one thing be more or less identical to another?) "and" that indeterminacy in identity is possible; hence, any incoherence in the idea of degrees of identity does not thereby undermine the idea of indeterminate identity. (shrink)

The role of microaggressions has gained increasing philosophical attention in recent years. However, microaggressions only tell part of the story. An often-overlooked component of inequality is the uneven and unjust distribution of microaffirmations. In this paper, I give a new definition of microaffirmations as signals that a recipient belongs to some valued or high-status class. Microaffirmations can—but need not—lead individuals to gain a sense of confidence, belonging, and merit. I then explain the harms of microaffirmations, arguing that when microaffirmations are (...) distributed inequitably, they can have larger ramifications for injustice, harming some vulnerable groups more than others. In addition, microaffirmations can lead individual actors to make choices based on who gives them microaffirmations and where they receive them, and thus can have outsized influence over the direction of an individual’s life because individuals tend to migrate to where they feel valued, appreciated, and included. I then turn to solutions to the problems I raise. I argue we should attend to and attempt to rectify inequalities in microaffirmations because doing so can help ensure not just the absence of negative attention, but also that the presence of positive attention is flowing in a just and equitable way.

Il y a un conflit entre les normes surnaturelles qui ne tiennent pas compte des possibilités humaines et les normes naturelles qui conduisent à des règles d’action fondées sur la connaissance positive du milieu où nous vivons ; mais il est impossible que les secondes affranchissent l’homme des premières. La question de leur accord se trouve donc posée.

It has been argued that neural networks and other forms of analog computation may transcend the limits of Turing-machine computation; proofs have been offered on both sides, subject to differing assumptions. In this article I argue that the important comparisons between the two models of computation are not so much mathematical as epistemological. The Turing-machine model makes assumptions about information representation and processing that are badly matched to the realities of natural computation (information representation and processing in or inspired by (...) natural systems). This points to the need for new models of computation addressing issues orthogonal to those that have occupied the traditional theory of computation. (shrink)
