Proxies of mate value must be evolutionarily salient. Gangestad & Simpson (G&S) have made a good case that fluctuating asymmetry is an important proxy of male mate value that correlates well with genetic and developmental quality. The use of financial variables as proxies for male investment ability by Gangestad, Simpson, and virtually every other investigator of human mating in evolutionary pe...

Coming on the heels of the publication of Tobacco Control’s Twentieth Anniversary issue (vol. 21, issue 2) comes another landmark: David Simpson is stepping down from his longtime position as editor for the journal’s News Analysis section, which he has held since shortly after the journal’s founding in 1992. Mr Simpson’s contributions to tobacco control are legion. Many across the globe, includ...

The Deligne-Simpson problem (DSP) (resp. the weak DSP) is formulated like this: give necessary and sufficient conditions for the choice of the conjugacy classes Cj ⊂ GL(n,C) or cj ⊂ gl(n,C) so that there exist irreducible (resp. with trivial centralizer) (p + 1)-tuples of matrices Mj ∈ Cj or Aj ∈ cj satisfying the equality M1 . . .Mp+1 = I or A1+ . . .+Ap+1 = 0. The matrices Mj and Aj are inter...

Brown and Simpson (1993) considered two versions of the Baire Category Theorem, which they called BCT-I and BCT-II . They showed that BCT-I is provable in RCA0, the subsystem of second order arithmetic specifying some basic algebraic properties of the numbers, induction for Σ 1 sets and the recursive comprehension axiom. Additionally, they showed that BCT-II is not provable in RCA0. Brown and S...

The first anesthetic for childbirth and the first recognition of the importance of hand hygiene in obstetrics coincidentally occurred within 5 months of one another in 1847. More than 150 years later, one would have thought that these milestone events would have been fully integrated into practice. However, individuals resist transformational change, which is defined as a fundamental alteration...
