Yoga is believed to have beneficial effects on cognition, attenuation of emotional intensity and stress reduction. Previous studies were mainly performed on eastern experienced practitioners or unhealthy subjects undergoing concomitant conventional therapies. Further investigation is needed on the effects of yoga per se, as well as its possible preventive benefits on healthy subjects. We investigated the effects of yoga on memory and psychophysiological parameters related to stress, comparing yoga practice and conventional physical exercises in healthy men . Memory tests, salivary (...) cortisol levels and stress, anxiety, and depression inventories were assessed before and after 6 months of practice. Yoga practitioners showed improvement of the memory performance, as well as improvements in psychophysiological parameters. The present results suggest that regular yoga practice can improve aspects of cognition and quality of life for healthy individuals. An indirect influence of emotional state on cognitive improvement promoted by yoga practice can be proposed. (shrink)

Language does not have to be held as a problem for radical enactivists. The scope objection usually presented to criticize enactivist explanations is a problem only if we have a referentialist and representationalist view of the nature of language. Here we present a normative hypothesis for the great question concerning the hard problem of content, namely, on how linguistic practices develop from minds without content. We carry representational content when we master inferential relations and we master inferential relations when we (...) master normative relations, especially when we are introduced into frameworks of authorizations and prohibitions. Inspired by the anti-intellectualism of the later Wittgenstein and Brandom’s inferentialism, we present the hypothesis that language emerges from inferentially articulated action from normative elements and not from manipulation in internal mental states of contents fixed by reference to external things.

Although various scholars underscore the importance of innovating responsibly in view of today's societal challenges, less attention has been paid to the entrepreneurial skillset, that is, the range of individual skills and organizational capabilities, that innovation-based organizations mobilize to deliver new responsible products and services. This paper thus explores the relationships between the entrepreneurial skillsets of 16 Canadian and Brazilian for-profit and not-for-profit organizations producing Responsible Innovations in Health (RIH) and their degree of responsibility. Our mixed methods study includes interviews (...) with entrepreneurs (n = 23) and fieldnotes as well as quantitative results from the RIH Assessment Tool. Our findings identify four skillset orientations—Technical, Technical + Business, Social, and Social + Business—that not only reflect (co)founders' training and entrepreneurial motivations but also a proclivity toward the consolidation of either “Technical” or “Social” skills and capabilities. Such consolidation is made possible by recruiting high-level executives with diverse backgrounds or by tapping on external knowledge sources (e.g., boards of directors, incubators, or volunteers). As five enterprises had no formal business skills, patterns associated to their overall RIH score (ranging from 1 to 5) reveal intriguing results. Organizations with a Social + Business skillset have a slightly lower RIH score (4.1) than those with a Social skillet (4.4) and those with a Technical + Business skillset have a slightly higher score (3.5) than those with a Technical skillset (3.0). The presence of business skills thus appears to mediate the relationship between entrepreneurial skillsets and the degree of responsibility, which may be linked to the distinct roles of ordinary (“doing things right”) and dynamic capabilities (“doing the right things”). These exploratory findings have scholarly and practical implications. First, the tensions and synergies characterizing responsible value creation should be approached by examining the complementary skills and capabilities that need to be assembled and consolidated. Second, the eight cases with a Social + Business skillset clarify the unique capabilities needed to produce highly responsible health innovations. Third, entrepreneurs with a scientific or engineering background should recognize that a Technical skillset is not enough. Fourth, recognizing that “falling in love with the cause” of RIH is not sufficient, investors and boards of directors should adequately support responsible entrepreneurs towards the proper orchestration of skills and capabilities that can reconcile economic and social goals.

Bernard Nieuwentijt ist in der Mathematikgeschichte bekannt als Kritiker der Leibnizschen Differentialrechnung. Im Gegensatz zu dem, was häufig angenommen wird, war die Kritik an Leibniz' Methode kein Hauptanliegen Nieuwentijts. Das Ziel seines bedeutendsten mathematischen Werks, Analysis infinitorum , war die Systematisierung und logische Deduzierung der ihm bekannten Infinitesimalmethoden, besonders derer von den Engländern wie Barrow, Wallis u. a. Das Werk Leibnizens war ihm anfangs völlig unbekannt. In dem System, das Nieuwentijt selbständig entwarf, rechnete er nicht mit Infinitesimalen höheren Grades: ihre (...) Existenz hielt er für unmöglich. Dies brachte ihn zur Kritik der Leibnizschen Methode, als er später auf dessen Werk stieß. Später aber erkannte er die Unhaltbarkeit seiner Kritik, wie klar wird aus seinem posthumen Werk Gronden van zekerheid . Der Aufsatz gibt überdies zur Fundierung dieser Thesen einen sehr kurzen Überblick über Nieuwentijts mathematische Arbeiten und eine Besprechung neuerer Interpretationen. (shrink)

From the beginning of the seventeenth century it has generally been held that the second Medicean is the parent of all the other extant manuscripts. In two articles C. W. Mendell has demonstrated that Leidensis B.P.L. 16. B is the manuscript once owned by Rudolphus Agricola and later by Th. Ryck, whose edition makes frequent allusion to its readings. Mendell's attempt to show further that L represents a tradition independent of the Medicean has found little support until recently, when E. (...) Koestermann, in the course of preparing the latest Teubner edition of Annals and Histories became convinced from his own study of L that Mendell's view—in spite of some arguments of dubious validity—was essentially correct. In an article in Philologus and in the preface to his edition of Histories Koestermann has marshalled the arguments which he believes prove L's independence of the Medicean line of descent. Since the new valuation that Koestermann puts upon L has produced a drastic revision of both text and apparatus criticus in his new editions, it may be worth while to examine the evidence that Koestermann adduces in support of his belief in L's independence.
