Muscle-power quality: does sex or race affect movement velocity in older adults?

To determine sex and race differences in muscle power per unit of muscle contraction, knee-extensor muscle power normalized for knee-extensor muscle volume was measured in 79 middle-aged and older adults (30 men and 49 women, age range 50-85 years). Results revealed that women displayed a 38% faster peak movement velocity than men and African Americans had a 14% lower peak movement velocity than Whites of a similar age when expressed per unit of involved muscle (p < .001). As expected, men exhibited greater knee-extensor strength and peak power per unit of muscle than women, but women had a faster knee- extension movement velocity per unit of muscle than men at the same relative strength level. Moreover, African Americans had greater knee-extensor muscle volume than Whites but exhibited lower knee-extensor strength and lower movement velocity per unit of muscle when tested at the same relative strength levels.     

Testing for abrupt breaks in variance structures with smooth changes

Abstract

We investigate the problem of testing for variance breaks in the case where the variance structure is assumed to be smoothly time-varying under the null. Since the classical tests are aimed to detect any change in the variance, they are not able to distinguish between smooth non constant variance and abrupt breaks. In this paper a new procedure for detecting variance breaks taking into account for smooth changes in the variance under the null is proposed. The finite sample properties of the test we introduce are investigated by Monte Carlo experiments. The theoretical outputs are illustrated using U.S. macroeconomic data.

论法律职业化的伦理精神

法律职业伦理精神在法律职业化进程中具有重大功能和作用,进而深刻地影响着法治现代化和司法现代化进程.关注人性的伦理精神,即尊重公民权利和限制国家权力,是法律职业化的逻辑起点;正义是社会体制的第一美德,崇尚正义的伦理精神构成了法律职业化的价值基础;法治是迄今为止人类治理国家和社会的最好模式,忠于法律的伦理精神是法律职业化的直接动力;珍视荣誉的伦理精神从内部维系着法律职业共同体并保证共同体的社会地位和声誉,是法律职业化的内在源泉.
