Furthermore, optimism, defined as the generalized expectation that good things will occur in one's life, is inversely associated with anxiety and depression, and is generally considered a positive health determinant during periods of increased stress [ 4].
Cryptochrome stability is a critical determinant of circadian period length, though the direction and magnitude of the period change associated with altered expression or stability of Cry1 and/or Cry2 seems to depend on the mechanism and context of altered stability (Vitaterna et al., 1999; Hirota et al., 2012; St John et al., 2014).
ρ i, the ratio of threshold value to the amplitude, was found to be an important determinant of the period MPS.
PER and TIM shift from the cytoplasm to the nucleus daily, and the length of time that PER and TIM reside in the cytoplasm is an important determinant of the period length of the circadian rhythm.
To account for the impact of the change in the exchange rate regime on the relation among interest rates and the selected determinants over this period, a dummy variable is used.
Longitudinal research is important for enabling tracking of behaviours and their determinants during this period of potential transition and the development of causal theoretical models of health behaviour.
Future research will have to identify possible determinants in the period following hospital discharge that can be used to prolong survival in these patients.
Solar activity is the primary determinant of TEC during periods with high solar activity, whereas periodic factors primarily contribute to TEC during periods with minimum solar activity.
Final Sertoli cell number is the main determinant (other than abstinence period) of sperm count in men (Sharpe et al. 2003).
A further complicating factors concerns the large time lag between childhood and adulthood; the longer the period between determinant and outcome, the larger the number of possible intermediate pathways.
