The purpose of this study was to explore the factor structutre Brief Self-Control Scale (BSCS; Tangney, Baumeister y Boone, 2004) used as self-report with a sample 151 children in Colombia (mean age 8.2 years, 50.33% girls and 49.66% boys) 115 Chile 7.3 53.04% 49.95% boys). scale also answered by 80 Colombian children’s mothers 38.3 years) Chilean 35.8 evaluate their self-control. Exploratory F...

This paper introduces three methodological advances to study the optimal design of static and dynamic markets. First, we apply a mechanism design approach to characterize all incentive-compatible market equilibria. Second, we conduct a normative analysis, i.e. we evaluate alternative competition and innovation policies from a welfare perspective. Third, we introduce a reliable way to measure co...

A famous theorem of P. Novikov 1955 and W. W. Boone 1959 asserts the existence of a finitely presented group with unsolvable word problem. In my Spring 2005 topics course (MATH 574, Topics in Mathematical Logic), I presented Boone’s proof, as simplified by J. L. Britton, 1963. In this seminar I shall present a truly slick, streamlined proof, due to S. Aanderaa and D. E. Cohen, 1980. Instead of ...

The ηL(1410) component of the η(1440) pseudoscalar has strong affinity for glue. But its mass is incompatible with lattice simulations that predict a much higher value for the 0 glueball. As a consequence it has been suggested that ηL(1410) could signal physics beyond the Standard Model. Here we argue that if glueballs are closed gluonic fluxtubes then ηL(1410) is a prime candidate for the 0 −+...

We present intermediate results on our ongoing investigation concerning semileptonic decays of heavy pseu-doscalar mesons into pseudoscalar and vector mesons. The corresponding formfactors are evaluated at several momenta and appropriate combinations of four light and four heavy quarks, which are chosen to allow for an extrapolation into the B Meson region. In order to obtain clear groundstate ...
