Effects of Surveillance on Intrinsic Motivation
Previous research indicates that explicit surveillance should induce subjects to attribute their performance at a task to the surveillance; hence, such subjects should persist to a lesser extent than subjects not exposed to such surveillance. Two forms of explicit surveillance were utilized: human and camera, as well as the appropriate opposites (human non- and camera non-surveillance). Subjects were directed to perform a model construction task, then were unobtrusively observed during a post-task “waiting period.” No difference in persistence was found for type of surveillance utilized. However, as predicted, subjects exposed to surveillance persisted less with the task materials than subjects not exposed
Interpolated measures with bounded density in metric spaces satisfying the curvature-dimension conditions of Sturm
We construct geodesics in the Wasserstein space of probability measure along
which all the measures have an upper bound on their density that is determined
by the densities of the endpoints of the geodesic. Using these geodesics we
show that a local Poincar\'e inequality and the measure contraction property
follow from the Ricci curvature bounds defined by Sturm. We also show for a
large class of convex functionals that a local Poincar\'e inequality is implied
by the weak displacement convexity of the functional.Comment: 25 pages, 1 figur
Effect of knocking down the insulin receptor on mouse rod responses.
Previous experiments have shown that the insulin receptor (IR) is expressed in mammalian rods and contributes to the protection of photoreceptors during bright-light exposure. The role of the insulin receptor in the production of the light response is however unknown. We have used suction-electrode recording to examine the responses of rods after conditionally knocking down the insulin receptor. Our results show that these IR knock-down rods have an accelerated decay of the light response and a small decrease in sensitivity by comparison to littermate WT rods. Our results indicate that the insulin receptor may have some role in controlling the rate of rod response decay, but they exclude a major role of the insulin receptor pathway in phototransduction
Quasisymmetric Koebe uniformization with weak metric doubling measures
We give a characterization of metric spaces quasisymmetrically equivalent to
a finitely connected circle domain. This result generalizes the uniformization
of Ahlfors 2-regular spaces by Merenkov and Wildrick
