It has been claimed that a broad attentional breadth buffers the impact of negative stimuli on human perception and cognition. Here we identify issues with the research on which this claim is based, and then rigorously test the claim. To induce narrow versus broad attentional breadth participants attended to the local versus global elements of Navon stimuli, and to investigate the impact of emotionally salient stimuli on performance we measured the effect of task-irrelevant stimuli of varying emotional salience (negative, neutral, (...) or positive) on task performance. Across a series of experiments, we found that the Navon stimuli were effective in inducing different attentional breadths, and that both negative and positive task-irrelevant stimuli slowed responses relative to neutral stimuli, but that the magnitude of this emotion-induced slowing was invariant to whether attentional breadth was broad or narrow. This indicates that a broad attentional breadth did not buffer against the effect of either negative or positive emotionally salient stimuli. These results challenge the claim the broadening attentional breadth protects against the impact of emotionally salient stimuli. (shrink)

A major barrier to recombination between bacterial species lies in the mismatch repair system, a complex of proteins that has evolved to proof‐read freshly replicated DNA. It now appears that a second system, involving an inducible DNA recombination, repair and mutagenesis pathway, also regulates interspecies recombination, but in a positive way, being required for recombination between Escherichia coli and Salmonella typhimurium(1). Thus the rate at which newly emerging species of bacteria diverge can be seen as a balance between a permissive (...) state associated with inducible repair and recombination, and the proof‐reading of intermediates in the recombination pathway by the mismatch correction system.

The problem of the one and the many is central to ancient Greek philosophy, but surprisingly little attention has been paid to Aristotle's treatment of it in the Metaphysics. The Central Books of the Metaphysics are widely recognised as the most difficult portion of a most difficult work. This title aims to examine the Central Books.

This paper introduces a new typology and associated measure of social and environmental mission integration by conceptually framing a feature of hybrid organizations—the degree of integration of their revenue model and social–environmental mission. The SEMI measure is illustrated using a hand-collected sample of 256 North American Certified B Corporations. We explore the heterogeneity of SEMI scores by identifying external-facing correlates and demonstrate non-congruence with Certified B Corporation’s audit results. Overall, our findings advance existing knowledge of these hybrid organizations and how (...) they balance their social–environmental missions with their economic objectives. (shrink)

This book discusses American pragmatism as it is found in the writings of its three major advocates: Charles S. Peirce, William James, and John Dewey. This book discusses each man's definition of pragmatism and shows how each of them applied it to one basic concept: Peirce to a theory of reality; James to a notion of truth; and Dewey to the concept of God.
