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.
Third, it is startling just how much difference changes in national inequality could make â suggesting support for greater attention to this is the key implication of all these future projections. Forecasts of global poverty are very sensitive to assumptions about inequality.In one scenario, we found that the difference between poverty estimated on current inequality trends versus a hypothetical return to âbest everâ inequality for every country could be an extra billion $2 poor people in 2030.hese kind of papers have significant policy implications because it is only by understanding both the future scale and anticipated locations of poverty that properly informed debates can be had on the scale and objectives of future international aid.
