Explaining variability
Orthodontic treatment is routinely described to last, on average, 24 months. Nonetheless, every orthodontist has already experienced that this time length shows huge variability, depending on several factors that are inherent to the operator, the patient, scientific knowledge and mastering of the mechanics used in orthodontic movement. It is very likely that there is something else, something s...
متن کاملExplaining variability in Early Paleoindian foraging
We have argued elsewhere [Cannon, M.D., Meltzer, D.J., 2004. Early Paleoindian foraging: examining the faunal evidence for large mammal specialization and regional variability in prey choice. Quaternary Science Reviews 23, 1955–1987] that the North American archaeofaunal record provides little support for the notion that Early Paleoindians across the continent practiced a uniform subsistence st...
متن کاملExplaining X-ray variability in blazars
The X-ray variability of blazars has been observed for many years. The X-ray emission mechanism is now reasonably understood, and, following observations such as the lag of the IR emission (ie the synchrotron component) by the X-rays, is usually explained as synchrotron self-Compton emission from the jet. The X-ray emission is observed to vary very rapidly, usually in a nonlinear way. Sometimes...
متن کاملExplaining the Increased Variability in Long-Term Interest Rates
M onetary policy affects the macroeconomy only indirectly. In the standard mechanism, changes in the federal funds rate, the Federal Reserve’s main policy instrument, lead to changes in longer-term interest rates, which in turn lead to changes in aggregate demand. But the links between the funds rate, long rates, and demand may be far from tight, and this potential slippage is a fundamental pro...
متن کاملExplaining variability in parasite aggregation levels among host samples.
Aggregated distributions among individual hosts are a defining feature of metazoan parasite populations. Heterogeneity among host individuals in exposure to parasites or in susceptibility to infection is thought to be the main factor generating aggregation, with properties of parasites themselves explaining some of the variability in aggregation levels observed among species. Here, using data f...
