Polarization is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is transverse to the direction of motion of the wave, so the oscillations can have different directions perpendicular to the wave direction. A simple example of a polarized transverse wave is vibrations traveling along a taut string; for example, in a musical instrument like a guitar string. Depending on how the string is p
The Future of Poverty: Framing Uncertainty 75 Given both the weak basis for forecasting and slow change historically in domestic distributions, a fundamentally ï¬ at forecast is a reasonable pattern for the base case.8 Patterns of Potential Human Progress Volume 1: Reducing Global Poverty Third, however, those scenarios also remind us that the future is not simply a matter of different human action patterns.
Each nation has its own threshold for absolute poverty line; in the United States, for example, the absolute poverty line was US$15.15 per day in 2010 (US$22,000 per year for a family of four), while in India it was US$1.0 per day and in China the absolute poverty line was US$0.55 per day, each on PPP basis in 2010.
