External knowledge sourcing in different national settings: a comparison of electronics establishments in Britain and France
2004
04001; International audience; In a detailed comparison of matched samples of electronics establishments in Britain and France, this paper finds that the two samples of establishments were operating in distinctively different national labour markets for engineers and scientists, reflecting structural differences in national higher education systems and a far higher level of individual mobility between enterprises in Britain than is found in France. These differences were found to have very little effect on quantitative measures of establishments' external research interactions which tended to reflect other national-institutional differences such as continued government support for public la…
Intra- and intergenotypic competition in Drosophila melanogaster: effects of density on larval survival and rate of development
1986
We have examined the effects of density and frequency in the larval competition of Drosophila melanogaster by measuring three fitness components: viability (V), mean development time (MDT) and a combination of these two (E). We have detected (contrary to most published results) non-linear effects of density in single-genotype cultures; in addition, different functions are required to describe the density effects below and above the optimal density. Frequency has also non-linear effects in the two-genotype cultures. Only one polymorphic equilibrium frequency, which is stable, occurs with respect to V; but two polymorphic equilibria, one stable and one unstable, exist with respect to E. The r…
Same Citius, Altius, Fortius…more women, crashes, and McTwists?
2013
Almost half of the record 98 events being held at the 2014 Sochi Winter Olympic Games were either not held 20 years ago at Lillehammer or have been substantially modified. The Olympics as a global sports event are not stationary but must adapt and evolve in response to changing demands, just as the remarkable athletes who are competing do. While the Winter Olympics program has steadily grown since Chamonix in 1924, the rate of development has greatly accelerated in the last 20 years. Three factors seem to be instrumental. First, the Winter Olympics program has become more gender balanced. Female hockey teams are battling for gold, and this year women will compete in ski jumping for the firs…
