Hypercompetitive Performance : Are the Best of times Getting Shorter ?
Hypercompetition” has been theorized to make competitive advantage increasingly more difficult to sustain in a wide range of industries. Further, sustained competitive advantage is now held to be less a matter of a single advantage maintained over time and more a matter of concatenating over time a sequence of advantages. This research examines 6772 firms in 40 industries over 25 years to disco...
متن کاملCoping with shorter days: do phenology shifts constrain aphid fitness?
Climate change can alter the phenology of organisms. It may thus lead seasonal organisms to face different day lengths than in the past, and the fitness consequences of these changes are as yet unclear. To study such effects, we used the pea aphid Acyrthosiphon pisum as a model organism, as it has obligately asexual clones which can be used to study day length effects without eliciting a season...
متن کاملShorter oars are more effective.
The purpose of this investigation was to clarify the effects of blade design and oar length on performance in rowing. Biomechanical models and equations of motion were developed to identify the main forces that affect rowing performance. In addition, the mechanical connection between the propelling blade force and the force that the rower applies on the handle was established. On this basis it ...
متن کاملAre winters getting warmer?
We examine whether any trends in monthly temperatures are the same through-out the year for various lengthy series. The data concern the world, the northern and southern hemispheres, and about three centuries of data for the United Kingdom and the Netherlands. For the empirical exercise, we rely on new and accurate tests which have been recently developed. These tests do not have standard distr...
متن کاملRacehorses are getting faster.
Previous studies have concluded that thoroughbred racehorse speed is improving very slowly, if at all, despite heritable variation for performance and putatively intensive selective breeding. This has led to the suggestion that racehorses have reached a selection limit. However, previous studies have been limited, focusing only on the winning times of a few elite races run over middle and long ...
