In clinical practice, headache diagnosis is often assumed to be relatively stable for an individual, and yet we have found headache frequency changes substantially over time, potentially moving individuals between diagnostic categories (i.e., between EM and CM).
Røed et al. (2008) show that while there was strong and monotone negative duration dependence in the employment hazard for Norwegian job seekers in this period, it tended to be relatively stable for Swedish job seekers, with a significant rise in transition rates around the time of passive benefit exhaustion.
If Obama follows his own pattern, the next few months should be relatively stable for him as well.
It was largely expected before the discovery of nobelium that in solution, it would behave like the other actinides, with the trivalent state being predominant; however, Seaborg predicted in 1949 that the +2 state would also be relatively stable for nobelium, as the No2+ ion would have the ground-state electron configuration [Rn]5f14, including the stable filled 5f14 shell.
Total PSA has been found to be relatively stable for 2 20 years at −20 °C (Woodrum and York, 1998; Ulmert et al, 2006), close to the storage temperature in the DoDSR (−30 °C).
Examination of the proportion of male births for the Aamjiwnaang community over the study period 1984 2003 shows that the proportion of male births appears to be relatively stable for the period 1984 1992; linear regression (r = 0.000) shows a slope not significantly different from zero (p = 0.990).
