The order in which the tasks were undertaken was inverted in half of the participants to average out differences in stimulus familiarity across tasks.
Exceptions are the female and the non-Western European subsample with significant differences in half of the covariates.
When investigating the reasons behind this, a study done in Sweden published in 1996 found that half of the difference between genders can be dismissed if you take out the days missed by pregnant women.
The difference in median age would then fall to approximately 12 years: in other words, almost half of the difference reported by Bowen et al (2008a) is simply a consequence of the fact that there are relatively few Black women over the age of 60 in Hackney.
The loss of the other three IRSs in the Atlantic salmon comprises almost half of the difference in the sizes between the introns (trout: 1264 bp; salmon: 964 bp).
The excess in gains of Yokkaichi patients reached approximately half of the difference in life expectancy between Yokkaichi patients and Mie Prefecture (Table 2 and Fig 3), suggesting that decrease in life expectancy was greatly due to respiratory mortality.
David Goldstein (Duke University, USA) described studies of the sustained virological response (SVR) following hepatitis C virus infection, in which GWASs identified the IL28B gene, explaining half of the difference in SVR between Europeans and Africans.
This is clearly accepted at policy level (for example, for NAEDI in England) and it is estimated that about half of the difference in survival is due to 'late diagnosis' (Abdel-Rahman et al, 2009).
Because the favorable interleukin 28B (IL28B) associated-single nucleotide polymorphisms (SNPs), leading to better response, exist at substantially greater frequency in European than African populations, they also explain approximately half of the difference in response rates between African-Americans and patients of European ancestry [29].
Renters are discouraged from moving by generous rent-control policies and public-housing programmes.Research by Peter Rupert of the University of California at Santa Barbara and Etienne Wasmer of Sciences Po in Paris suggests that housing-market frictions may account for about half of the difference in mobility rates between Europe and America.
