Effective Measures of ''Effective Discharge''
World Environmental and Water Resources Congress 2008, 2008Abstract The concept of effective discharge, Qe, was introduced by Wolman and Miller (1960) as that stream discharge that transports the most sediment over time. Recently, the validity of Qe as an overall descriptor of sediment transport has been questioned because of its various interpretations and methods of calculation.

Effective effective interactions
The European Physical Journal A, 2003The use of effective field theory techniques allows the basic physics to be extracted from otherwise complex systems. We cite examples from quantum mechanics, condensed-matter physics, QCD, and quantum gravity.

Scientists and technologists have long used the word effect-as in the Doppler effect, the butterfly effect, and the greenhouse effect-to good effect. In fact, effect has been so, uh, effective at naming things that it has branched out into the mainstream.

Business model (BM) visualisations have become popular instruments with which to explain and manage today's complex business interactions. Using verbal and graphic elements, they provide simplified representations of reality and can support BM tasks that go beyond working memory's capacities.

Environmental influences resulting in epigenetic mediation of gene expression can affect multiple generations via direct effect (first generation); direct or maternally mediated effects on the fetus (second generation), or gonadal cell lines of the fetus (third generation) when pregnant animals are exposed to the stimuli; and through generational ...

Treatment effects and placebo effects
BMJ, 2015Researchers investigated the effectiveness of iron supplementation on reducing fatigue in non-anaemic women with unexplained fatigue. A double blind randomised placebo controlled trial was performed. In total, 144 women aged 18-55 years were recruited from an academic primary care centre and eight general practices in western Switzerland.

Fixed Effects and Random Effects
2008One of the major benefits from using panel data as compared to cross-section data on individuals is that it enables us to control for individual heterogeneity. Not controlling for these unobserved individual specific effects leads to bias in the resulting estimates.
