In the present study, three experimental groups of rats were orally exposed to PCBs typically found in human breast milk and then behaviorally tested for changes in measures of stimulus control (percentage lever-presses on the reinforcer-producing lever), activity level (responses with IRTs > 0.67 s), and responses with short IRTs (< 0.67 s).
In the major economies, monetary policy is approaching the limits of what they can do.He adds that central banks have two levers; the level of rates and the amount of base money (banking liquidity).
Similarly, the two animals that received misplaced CART injections (M = 64.5, SE = 22.5) responded on the active lever at a level almost identical to controls, but higher than the PVT-directed 0.625 µg CART (M = 19, SE = 6.47) and 2.5 µg CART (M = 14.17, SE = 4.73) groups.
For convenience, the indifference level between lever S and lever C was set at 0. Values above 0 indicated a preference for lever S (i.e., selection of lever S>50% of completed choice trials) while values below 0 indicated a preference for lever C (i.e., selection of lever C>50% of completed choice trials).
Many students consider the applied nature of criminology and criminal justice as a lever into higher levels of the job market.
A compact planar three-degrees-of-freedom (3-DOF) nanopositioning platform is described in which three two-level lever amplifiers are arranged symmetrically to achieve large magnification.
A simulator set up at the lab in Liverpool with just two levers shows the level of simplicity they are aiming for.
For the fifth year in a row, California ranked first in Clean Edge's "U.S. Clean Tech Leadership Index," thanks to the State's "clean-tech prominence," "effective policy levers at every level of government," and "a green-minded populace".
A pole 15 feet high in the centre of the arch at the Stretford bank supported a semaphore system with two arms on each side, operated by levers at ground level.
Decisions about the choice of the technique (long lever to manipulate multiple levels or short lever to manipulate one specific level) and the location of the forces are left to the discretion of the PTs.
