However, most studies testing this hypothesis have either not manipulated the presence of engineers, or have transplanted engineers into areas already dominated by other engineers, which limits the ability to assess the relative engineering effects.
A further shortcoming of the current state of the art relates to the fact that most studies testing this hypothesis were restricted to samples of working men and women from a single country or from different countries, mostly within Europe [ 11- 13].
Most studies tested a hypothesis of non-inferiority (36%%) or equivalence (24%%), while 16%% of studies aimed to demonstrate superiority.
Most studies tested models involving this hierarchical cognitive structure.
As most studies tested holiday effects in several subgroups it is necessary to take multiple testing into account.
As most studies tested many markers, we coded each report according to whether some, all, or no tested hypotheses were positive.
Thus, most studies tested 5-HTTLPR, in conjunction with between-subject differences in levels of stress, on predicting individual differences in depression.
A Cochrane review updated in 2007 6 concluded that little evidence supports the effectiveness of scientific peer review, since most studies tested the specific effects of masking either authors or reviewers.
Most studies tested the efficacy of any form of heparin to other anti-coagulants for indications including anti-phospholipid antibodies with prior loss, thrombophilias, unexplained repeated pregnancy loss, and cardiac indications.
However, because most studies test the cumulative aversive effects of genotype and environment (i.e., dual risk), rather than differential susceptibility or vantage sensitivity, we solely reviewed findings involving environmental adversity (i.e., the "for worse" part).
Most studies test pitch or timbre discrimination (Gougoux et al., 2004; Doucet et al., 2005), or localization of single sounds in space (Lessard et al., 1998; Roder et al., 1999), which do not require estimation and comparison of positions in space.
