The chances of Ohuruogu escaping punishment when she appears before a UK Athletics disciplinary hearing on a date to be decided appear slim, because she has apologised in a statement that failed to offer any explanation beyond a change in her "training circumstances".
Another potential explanation is a change in the referral patterns, with nearby hospitals now sending more of their sickest patients hoping for better care and resources not previously available in the casualty room.
In case we still find an effect of unemployment on absences, we can argue that this behavior is affected by the incentives of workers to take sick leave, and we can confidently exclude the alternative explanation of a change in the composition of the workforce.
Again, the likely explanation is a change in PKC turnover.
One explanation for a change in molecular conductance is the reduction or oxidation of a neutral species.
A possible explanation is a change in the overall shape of the protein and thus its hydrodynamic radius, when the potentially flexible C-terminal residues are present.
The simplest explanation is a change in the ratio of DNA that codes for proteins versus non-protein coding DNA [ 29].
Changes in the motility of diamagnetically levitated flies [ 27] could be an explanation for a change in the oviposition rate; embryo retention is a typical behavioural response to environmental stress.
One plausible explanation is a change in the transmission route from blood transfusion and/or blood products, operations, surgeries and dental procedures to a route of intravenous drug use (IVDU) and high-risk sexual behavior (HRSB) [ 18, 20].
Although the changes in codon usage observed in the P. tremula lineage are consistent with an increase in the strength of natural selection acting on codon usage, an alternative explanation is a change in base composition driven by changes in mutational biases.
Plausible explanations include a change in fire regime resulting from human-lit fires, a change in fire regime following extinction of megafaunal browsers, and/or a threshold response to increasing aridity.
