However, as stopping was contrasted directly with infrequent shifting, present functional group differences are unlikely to result from such factors.
It is difficult to interpret the present findings within the context of these studies as task requirements were very different, with infrequent shifting requiring no change in overt responding [Dodds et al., 2011].
Second, it must come to terms with the fact that China's rise and America's decline are not simply a result of a failure of policy but are rather one of those great — and highly infrequent — historical shifts that governments can do relatively little to affect, let alone prevent.
Our main finding is that, for the nine series we analyze, specifications with infrequent and large shifts in error variances outperform both fixed parameter specifications and smooth, continuous shifts when it comes to interval coverage.
Respiratory distress and anaemia, together with the clinical sign of prostration, are the most prevalent presentations of severe malaria, with the majority of cases occurring in younger children, as opposed to coma, which is infrequent and slightly shifted to older children [33].
In the second mechanism, overlapping genes are alternately translated through infrequent ribosomal frame-shifts of a single mRNA transcript.
The important thing to remember is that broad, secular shifts, while infrequent in occurrence, present extraordinary opportunities for those fortunate enough to capitalize on them.
We observe that allowing for infrequent and large parameter shifts while imposing normal and homoskedastic errors often leads to erratic forecasts, but that the model typically forecasts well if it is made more robust by allowing for non-normal errors and time varying variances.
Demographic shifts are infrequent in this area, and the population can be followed long term.
The results show that recent jumps to distantly related hosts (from different subgenera) are relatively infrequent and limited to one "shifted" new species per lineage (see above).
