(drama), truth of character is properly sacrificed to other objects, such as the main effect. It may also be asked whether the characters are simple, as some people are in actual life, or complex, like most interesting persons; whether they develop, as all real people must under the action of significant experience, or whether the author merely presents them in brief situations or lacks the power to make them anything but stationary.
Unity means that everything included in the work ought to contribute directly or indirectly to the main effect. Very often a definite theme may be found about which the whole work centers, as for instance in 'Macbeth,' The Ruin of a Man through Yielding to Evil.
The main effect from asset purchases was more of a signal that interest rates would remain near zero for longer.
For RTs, the main effect of modality was significant ( F [sub](1,53)= 8.73, P = 0.005, ?2 = 0.14), indicating that RTs were significantly slower in the single auditory task (674 [+ or -] 15 ms) than in the single visual task (642 [+ or -] 11 ms).
Analysis of response accuracy data revealed a significant main effect of predictability, F(1, 30) = 5.15, p = .031, [[eta].sup.2.sub.p] = .15, showing higher accuracy for predictable versus unpredictable faces, and a significant main effect of sex, F(1, 30) = 5.48, p = .026, [[eta].sup.2.sub.p] = .15, reflecting higher accuracy for women than for men.
Some parts of the world warm faster than others, such as the Arctic, but the main effect is the change in weather patterns.
Main effect of row spacing and different levels of blended fertilizer rates did not show significant variation for days to 50% flowering but highly significant effect (P<0.01) was observed between varieties on days to flowering (Table 2).
The phrase "response time" should be replaced with the phrase "main effect." The correct table is shown below.
For BMC, there was a main effect of jump training after just 2 wks, but the diet did not (P=0.854), and there was no interaction between jump training and diet (P=0.082).
In the main effect cutting schedules C1 (28 days) produced significantly higher CP (12.48%) than C2 (35 days) and 21.03% higher than C3 (42 days) during first year (Table 1), whereas during second year, C1 (28 days) produced significantly higher CP (12.20%) than C2 (35 days) and 21.40% higher than C3 (42 days) (Table 1).
On an open free-flowing highway, the main effect is on the lush verge vegetation but standing in a queue at traffic lights or crawling in a confined urban space must be when risks are highest and I would question if the modifications used to reduce emmisions under test might also be applicable under these conditions.
