The data distribution method, involving absence of overlap in measures of variability, is held to be potentially statistically significant.
Since institutional care involved absence from domestic work, potential disruption to the family also had to be considered.
Expectations of repeatedly finding associations between given genes and phenotypes have been borne out by studies of parallel evolution, especially for traits involving absence or presence of characters.
Of the 82 MDR isolates (20 onset and 62 fifth month), the predominant patterns involved absence of WT8 with either S315T1/2 or Δ-8 mutations (Table 3).
One explanation for this may be that the phenotypes of healthy aging and longevity may be much more complex than those of these complex diseases, in part because they often (depending on phenotype definition) involve absence of specific complex diseases.
Some phenomena involving absences may be tough to categorize.
More generally, he argues that theories of causation as an intrinsic relation are overhasty generalisations of one specific kind of causation, and they fail to do justice to our intuitions about causation involving absences (as causes, effects or intermediaries).
(1971, p. 425; see also Dowe 2001, Hall 2004) Indeed, since disconnections look to involve preventions of would-be-preventers, and since prevention looks to involve absences, one might reject causation by disconnection for the general reason that there is no absence causation (Moore 2009).
Hibernation involves the absence of temperature regulation for long periods in addition to adaptations of circulation, respiration, and renal function and the suspension of most aspects of activity.
Partial pulmonary artery agenesis involves an absence of the proximal portion or a rudimentary pulmonary artery.
