This is analogous to the notion that reciprocity is hard to sustain in large groups because withdrawing cooperation punishes everyone in the group, defectors and cooperators alike (Boyd & Richerson, 1988).
However, in the majority of low-income countries, cytologic screening has proven difficult to sustain, in large part because of its reliance on highly trained cytotechnologists, high-quality laboratories, and an infrastructure to support up to 3 visits for screening, colposcopic evaluation of abnormalities, and treatment.
Therefore, whether such reductions sustain in larger datasets warrants further investigation.
Remarkably, the absence of both Aiolos and OBF-1 resulted in elevated λ5 mRNA levels in pre-BI cells, which were sustained in both large and small pre-BII cells (Figure 4A).
Where discrete general practice models can be sustained in sufficiently large country towns, alternative hub-and-spoke models may be required for delivering a full range of PHC services to smaller, more isolated communities.
In fact the efficiency analysis will be done including all interventions aimed to be sustained in the large-scale implementation phase.
Complaints of brutality were 94% less likely to be sustained in Chicago than in other large police departments in 2004, Mr Futterman reports.
While the upper Bow does hold trout, its icy, glacial-fed waters do not sustain fish in large numbers.
Rather, it raises the question of whether existing energy consumption could be sustained in a future when a larger proportion of energy was derived directly from unfossilised plant matter, or "biomass" as it is sometimes referred to in this context.
Due to this decoupling of reliance on reef habitat and the potential benefits they may glean from increased food resources, this may be the group that will be sustained in the long term, although a large amount of variation can be expected at the species level [15], leading to changes in community composition.
