STUDY DESIGN Siberian Yupiks of various ages were recruited from three populations: residents of the village of Gambell, residents of the village ...

METHODS As part of on-going community-based participatory research (CBPR) studies on SLI, 5 discrete exposure-assessment projects were conducted: (a) a biomonitoring study of human blood serum; (b-d) 3 investiga...

A Note on the Lawrence-Krammer-Bigelow Representation

A very popular problem on braid groups has recently been solved by Bigelow and Krammer, namely, they have found a faithful linear representation for the braid group Bn . In their papers, Bigelow and Krammer suggested that their representation is the monodromy representation of a certain fibration. Our goal in this paper is to understand this monodromy representation using standard tools from th...

Ecology and evolution on the banks of the St Lawrence.

The population biologist John Harper (1967) wrote that ‘the theory of evolution by natural selection is an ecological theory, founded on ecological observation by perhaps the greatest of all ecologists’. More than 40 yr since this observation, it is surprising that the professional societies devoted to the study of ecology and evolution still remain largely distinct (for example, consider the S...
