Research on testosterone-behavior relationships in humans is assessed in relation to a version of the challenge hypothesis, originally proposed to account for testosterone-aggression associations in monogamous birds.
In any event, all that is required to falsify the Wilcox-Russell hypothesis in relation to a particular variable is to show that the birth weight distribution and the birth-weight-specific mortality curve do not shift horizontally together to the same extent that is, that there are significant indirect effects operating through birth weight.
In relation to a 'metabolic rate hypothesis', rates of mtDNA evolution are postulated to be affected primarily by by-products of respiration (e.g. oxygen radicals) which can cause mutations in DNA.
In relation to the hypothesis, a negative coefficient indicates that a country where large firms seem dominant would tend to have lower entrepreneurial activities and intentions.
In relation to the second hypothesis, a positive intention to seek help from a healthcare professional at baseline did not predict subsequent mental health service use and over 12 months, and there was no association between a positive intention to seek help from a healthcare professional at baseline and subsequent 12-month mental health service use.
In relation to the security hypothesis, a different approach is necessary.
Finally, the present results were discussed in relation to the hypothesis according to which the focal and the postural components are parts of the same motor program.
The key findings of this study in relation to our hypothesis is that, as predicted, L-Dopa medication restored the function of the motor cortico-striatal loop, during the execution of a set-shift since significantly more activation was found in the PMC during the ON vs. the OFF state when matching after negative feedback was compared with control matching (Figure 5).
In relation to this hypothesis, differences in immune effectiveness between asexual and sexual forms have been predicted [ 8].
The significance of these results is discussed in relation to the hypothesis that diol-epoxides are important in the metabolic activation of polycyclic hydrocarbons like benzo[a]pyrene.
