Thus, a core feature of childhood ADHD is the variability of the nature and timing of behavioural responses.
No correlations were calculated with the other outcome variable, Number of events reported, because of the lack of variability and skewed nature of this item (40% of the respondents indicated not to have reported any events during the past 12 months and 41% had reported only one or two events).
No correlations were calculated with the item number of events reported, because of the lack of variability and skewed nature of this item (90% of the respondents indicated not to have reported any incidents during the last twelve months).
Motivated by previous studies at the site that indicated riverbed clogging plays an important role in the performance of the riverbank filtration system, we investigated the spatiotemporal variability and nature of the clogging.
53 Effectiveness studies on the other hand tend to be more pragmatic in nature, allowing natural variability of patient populations, intervention administration, and follow-up durations to factor into the analyses.
The high inter- and intraclass variability of garments, the continuous nature of the possible deformations of cloth and the evident difficulties in predicting their localization and extension on the garment piece are challenges that have encouraged the researchers to provide a plethora of methods to confront such problems, with some promising results.
Such genetic rearrangements, positive selection, and recombination events act to increase the chemical variability of microcystins found in nature.
Completely faithful recapitulation of such constrains is not possible under laboratory conditions, not the least due to the variability of such events in nature.
If the timing of aging is to some degree set by developmental processes, then this would help explain the great variability of lifespans observed in nature.
To explain the apparent conservation of core genome regions, and reconcile it with the apparent variability of SAR11 genomes in nature, we hypothesize that the large population sizes of SAR11, and the age of these clades that is inferred from phylogenies, have allowed them to accumulate very extensive variation in genome properties that are selectively neutral [ 2].
