We conduct an experimental test of the long-standing conjecture that autonomy increases motivation and job performance. Subjects face a menu consisting of two projects: one risky and one safe. The probability that the risky project succeeds depends on the subject’s effort. In one treatment, subjects choose a project from the menu; in the other treatment, they are assigned a project from the men...

In his recent paper, “What a Real Argument is,” Ben Hamby attempts to provide an adequate theoretical account of “real” arguments. In this paper I present and evaluate both Hamby’s motivation for distinguishing “real” from non-“real” arguments and his articulation of the distinction. I argue that neither is adequate to ground a theoretically significant class of “real” arguments, for the articu...

We enumerate unrooted planar maps (up to orientation preserving homeomorphism) having two faces, according to the number of vertices and to their vertex and face degree distributions, both in the (vertex) labelled and unlabelled cases. We rst consider plane maps, i.e., maps which are embedded in the plane, and then deduce the case of planar (or sphere) maps, embedded on the sphere. A crucial st...

MACAQUE’S PRIMARY VISUAL CORTEX WAHIBA TAOUALI, GIACOMO BENVENUTI, FRÉDÉRIC CHAVANE, AND LAURENT U. PERRINET Institut de Neurosciences de la Timone UMR7289, CNRS & Aix-Marseille Université 1. MOTIVATION 1. When an oriented moving bar reaches the classical receptive field (cRF) of V1 neurons, how are directional and orientational (tuning) information dynamically encoded in their activity? 2. How...
