Simple race models of attention have been proposed (Shibuya and Bundesen, 1988, Bundesen, 1987) but our best current theories supplement the simple race mechanism with some components of mutual struggle, or with additional processes of top-down control (see Bundesen and Habekost, 2008).
Competition based mechanisms for achieving selectivity come in at least two varieties: In a simple race mechanism each of the competitors independently completes a process that is comparable, along some dimension of variation, with the processes completed by the other competitors.
Using these criteria, the boundaries between quasihomogeneous and relay-race mechanisms are determined experimentally as a function of the initial organization of the reaction medium (i.e., particle size and porosity).
In the relay-race mechanism, while planar at the macroscopic level, the combustion front profiles are irregularly shaped, with arc-shaped convexities and concavities at the microscopic level.
It is unfortunate that anyone, regardless of age, gender, race or mechanism of injury, die in war, but that's what warriors do when called upon.
The two groups (NPWT and vessel loop) were statistically similar in regards to age, race, gender, mechanism of injury, presence of vascular injury, open fracture, infection and length of stay (Table I).
At the center of the yearslong battle over the constitutionality of affirmative action was Abigail Fisher, a white woman who sued UT after she was denied admission under the school's Top 10 Percent rule, a "race-neutral" mechanism that automatically grants admission to top-performing high school students across Texas.
As a result both sexes can become involved in a sexually antagonistic arms race and evolve mechanisms to gain control over reproduction, regardless of the costs to the other sex [ 15, 16].
However, the existing tools for such task are either too slow or hard to extend the race condition detection mechanism.
Covariables included patient (age, race, gender, insurance, mechanism of injury, injury severity score (ISS)), provider (ATLS certification) and hospital (trauma level designation) characteristics.
It is part of the ideological framework of redressing the race and class exclusion mechanisms of artisans and others from the landscape of skills possession.
