The inclusion of a second harmonic in the solution does result in changes to the response, especially the softening behaviour, but overall it has a small effect for the system parameters chosen in this paper, which is representative of a quasi-zero stiffness isolator.
However, when the rate for closing was 20%, then closing schools for 14 days had a smaller effect on hospitalization rates than closing for 7 or 21 days.
While odds ratios changed markedly after age adjustment, additionally adjusting for IRSD score had a smaller effect.
This has a small effect on, for example, the estimated long-run interest rate, but has no effect on the correlation results.
Portes says that a highly restrictive immigration policy might have a small effect on wages for low-skilled workers but little or none for medium and highly skilled workers.
Alternatively, many association studies of schizophrenia have been performed because genetic association methods are a more powerful means for finding genes that are expected to have a small effect on risk for the disorder.
Most of the time, the markers identified by genotyping are common variations that have a small effect on risks for common conditions.
All of these SNPs have at some stage been suggested as susceptibility polymorphisms for schizophrenia (e.g., 16,17), but current meta-analyses do not support their role in etiology of the disease itself with the exception of the 5-HT2AR A-1438 G polymorphism, which may have a small effect on the risk for schizophrenia (SchizophreniaGene: http://www.schizophreniaforum.org/res/sczgene) (18).
Rotation length had only a small effect; for an equivalent log height, there was an increase in log average density of 2 4 kg m−3 for each 5 year increase in rotation length.
