Competition: our constant companion

Competition: our constant companion.

641 Competition is at the heart of every step we make during our careers as research scientists. We first compete for a place in a laboratory to carry out our PhD research. We then compete for postdoctoral fellowships. And as heads of laboratories, in a way that is perhaps unique to research, we compete for funds to finance the experiments performed in our laboratories. It is not an exaggeratio...

CBOT: our constant challenge

CBOT: o nosso desafio constante Recently, we had another Brazilian Congress of Orthopedics and Traumatology (CBOT), this time in the city of Rio de Janeiro, with its beauty and joyfulness and the warmhearted competence of its inhabitants. Rio has a great tradition of congresses, starting with the one at the Quitandinha, the first major Brazilian congress, and continuing to today's international...

Measuring Hubble’s Constant in our Inhomogeneous Universe

Recent observations of Cepheids in the Virgo cluster have bolstered the evidence that supports a Hubble constant in 70−90 km sec−1 Mpc−1 range. This evidence, by and large, probes the expansion of the Universe within 100Mpc. We investigate the possibility that the expansion rate within this region is systematically higher than the true expansion rate due to the presence of a local, large underd...

Electronic Companion to: What matters in school choice tie-breaking? How competition guides design

We break Theorem 3.2 into several smaller (sub-)theorems and prove each one separately. This is done in sections 1.1, 1.2, and 1.3, which state and discuss the theorems about stochastic dominance, Pareto improving pairs, and variance, respectively. The theorems stated in these sections are then proved separately in the later sections. Section 2 contains the proofs for stochastic dominance. Sect...
