SVC bitstream adaptation in MPEG-21 multimedia framework

INTRODUCTION Scalable video coding (SVC) (Schwarz et al., 2004) is the most promising video format for appli- cations of collaborative communication. First, SVC format, which is extended from the latest advanced video coding (AVC), is appropriate for creating a wide variety of bitrates with high compression effi- ciency. Second, an original SVC bitstream can be easily truncated in different ways to meet various characteristics and variations of devices and connec- tions. The scalabil…

流行天下:二十一世纪中国女性文学观察

二十一世纪女性文学以流行天下的姿态占据了新世纪中国文学的开端。它的流行有其重要原因,即社会进步与女性地位提高的时代环境;实力作家与作品实力的魅力征服;调情撒娇与话语放纵的市场策略;名家渴盼与隐私窥探的阅读期待。这种流行预示着文学写作“她世纪”的来临。     

21世纪世界格局展望

自60－70年代以来，世界格局就出现了多极化的趋势，冷战结束后，世界明显向着多极化方向发展。到21世纪，世界将形成以美国、中国、俄国、日本、德国五大主权国家构成的多极格局。本世纪末由这几个大国形成的纵横交错的大小三角关系，已经构筑了这种格局的基本框架和战略态势。

Comparing teacher salaries: Insights from the U.S. census

Teachers are more likely to be found in rural communities and low-wage metropolitan areas than are college-educated workers in other occupations. This analysis explores the extent to which the geographic distribution of teachers explains the relatively low average wage found in other studies. The analysis suggests that excluding geographic indicators from the analysis downwardly biases estimates of relative teacher wages. One important implication of these findings is that researchers should pay attention to geographic wage variations when making earnings comparisons between teaching and other occupations.     

Incentives and effort in the public sector: Have US education reforms increased teachers’ work hours?

Beyond some contracted minimum, salaried workers’ hours are largely chosen at the worker's discretion and should respond to the strength of contract incentives. Accordingly, we consider the response of teacher hours to accountability and school choice laws introduced in US public schools over the past two decades. Total weekly hours of full-time teachers have risen steadily since 1983 by about an hour, and after-school instructional hours have increased 34 percent since 1987. Average hours and the rate of increase also vary widely across states. However, after accounting for a common time trend in hours, we find no association between the introduction of accountability legislation and the change in teacher hours. Education reforms are, however, associated with an increase in student test scores, presumably due to other types of changes in school and teacher behavior.     

Three measures of returns to education: An illustration for the case of Spain

In this article, in a context of wage equations with sample selection, we propose a novel interpretation of the partial effects linked to education as additional measures of returns to education that complement the traditional one, which is directly obtained from the estimation of the wage offer equation. Using European Household Panel data for Spain these partial effects were calculated. The results show that there are incentives in Spain for investing in education not only because it means an increase in wages but also because it raises the probability of obtaining any wage at all.
