Mandarin Neutral Tone—does it Change Target
It is known that in Mandarin each of the five lexical tones can be assigned with an articulatorily functional target: [high] for tone 1, [rise] for tone 2, [low] for tone 3, [fall] for tone 4 and [mid] for tone 5 (the first four tones are known as full tones while tone 5 is called neutral tone). Given that the targets of full tones can change (e.g., from tone 3 to tone 2) in certain speech cond...
متن کاملCapital Intensity, Neutral Technological Change, and Earnings Inequality
The paper furthers the neoclassical theory of earnings inequality. The inequality multiplier is derived as the amount by which inequality in skills must be multiplied to yield earnings inequality. Neutral technological change and the real interest rate affect inequality by changing capital per worker. The effect of capital per worker on the inequality multiplier is related to skill differential...
متن کاملA non-equilibrium neutral model for analysing cultural change.
Neutral evolution is a frequently used model to analyse changes in frequencies of cultural variants over time. Variants are chosen to be copied according to their relative frequency and new variants are introduced by a process of random mutation. Here we present a non-equilibrium neutral model which accounts for temporally varying population sizes and mutation rates and makes it possible to ana...
متن کاملFunctional DNA Positions Change as Frequently as Do Neutral Ones
Much work has been done in statistically describing how DNA changes through evolution. Relative to models for neutral DNA sequence positions, models for functional DNA sequence positions usually include a far-from-uniform equilibrium probability distribution and a significantly reduced rate of change. We examine the mathematical basis for these modifications to the functional-DNA model. We find...
متن کاملHow range shifts induced by climate change affect neutral evolution
We investigate neutral evolution during range shifts in a strategic model of a metapopulation occupying a climate gradient. Using heritable, neutral markers, we track the spatio-temporal fate of lineages. Owing to iterated founder effects ('mutation surfing'), survival of lineages derived from the leading range limit is enhanced. At trailing limits, where habitat suitability decreases, survival...
