If R 1 and R 2 are the rate of responses on two schedules that yield obtained (as distinct from programmed) rates of reinforcement Rf 1 and Rf 2, the strict matching law holds that the relative response rate R 1 / (R 1 + R 2) matches, that is, equals, the relative reinforcement rate Rf 1 / (Rf 1 + Rf 2).

Variable-time schedules are similar to random ratio schedules in that there is a constant probability of reinforcement, but these reinforcers are set up in time rather than responses. The probability of no reinforcement occurring before some time t’ is an exponential function of that time with the time constant t being the average IRI of the ...
Let be a metric space with distance function .Let be a set of indices and let () be a tuple (indexed collection) of nonempty subsets (the sites) in the space .The Voronoi cell, or Voronoi region, , associated with the site is the set of all points in whose distance to is not greater than their distance to the other sites , where is any index different from .
A reinforced concrete column is a structural member designed to carry compressive loads, composed of concrete with an embedded steel frame to provide reinforcement. For design purposes, the columns are separated into two categories: short columns and slender columns.
An odds ratio greater than 1 indicates that the condition or event is more likely to occur in the first group. And an odds ratio less than 1 indicates that the condition or event is less likely to occur in the first group. The odds ratio must be nonnegative if it is defined. It is undefined if p 2 q 1 equals zero, i.e., if p 2 equals zero or q ...
Coding (primary, FSIQ) – children under 8 mark rows of shapes with different lines according to a code, children over 8 transcribe a digit-symbol code using a key. The task is time-limited. Symbol Search (primary) – children are given rows of symbols and target symbols, and asked to mark whether or not the target symbols appear in each row.
The approximation ratio is defined as the ratio of the computed solution length to the optimal length for a worst-case instance, one that maximizes this ratio. Because the NP-hardness reduction for the k -minimum spanning tree problem preserves the weight of all solutions, it also preserves the hardness of approximation of the problem.
