Advancing Strategic Entrepreneurship Research: The Role of Complexity Science in Shifting the Paradigm

Minet Schindehutte, Michael H. Morris
2009 Entrepreneurship: Theory & Practice  
Using this lens, a rearticulation of SE is proposed that centers on the notion of an opportunity space and a paradigm built around forms, flows, and functions.  ...  Complexity science is presented as an alternative theoretical lens for addressing these issues, and enhancing the potential of SE in a world characterized by fluctuations, irreversibility, nonlinearity  ...  The word "novel" is used liberally by scholars, but not always correctly.  ...

New microcrystalline catalysts

John Meurig Thomas
1990 Philosophical Transactions of the Royal Society of London Series A Physical and Engineering Sciences  
Catalysts themselves, though they should in theory remain unchanged, are consumed during use, chiefly because of mechanical attrition.  ...  Plausible mechanisms of Phil. Trans. R. Soc. Lond. A (1990) 175 catalysed conversions abound, some commended by their immediacy, very few by their demonstrated veracity.  ...  At first, using relatively primitive molecular mechanics procedures (Thomas & Ramdas 1985; Ramdas et al. 1984; Wright et al. 1985) it was possib simple notions of shape selectivity, and then to estimate  ...

Darkened Counsel: The Problem of Evil in Bergson's Metaphysics of Integral Experience

Anthony Paul Smith
2016 Journal of French and Francophone Philosophy  
A theodical structure is one that, at bottom, justifies the experience of suffering by way of a concept of the whole or some concept that functions to subsume everything within it.  ...  This essay presents a counter-narrative to that reading by looking to the place of the problem of evil within his integral metaphysics.  ...  Written in the aftermath of World War I and before the next wave of mass suffering, Bergson turns to the problem of mechanization and the way that science had been captured by the demand to create machines  ...
