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.
In the United States, the federal poverty line â an absolute measure of annual income â is frequently used to determine who is categorized as poor (Ferris & Stein, 2008, 2010). Currently the government defines the poverty line as an income of $11,139 for an individual and $22,314 for a family of four (Censky, 2011). In sociology, poverty can be defined using two terms â relative deprivation and absolute deprivation. Relative deprivation is a comparison between people and social class.
