A physically literate individual is expected to be cognitively knowledgeable, physically competent, and mentally motivated for a physically active life throughout the lifespan. The advancement of technology in recent years, especially those in active video games（AVGs）, seems to have allowed the mind-body integrated physical activity accessible to children at all ages. This article reviews findings from research and critique research on AVGs in light with the theoretical and pedagogical tenets of physical literacy and, on the basis of the review, elaborates the potential that AVGs could contribute to enhancing children＇s physical literacy.展开更多

Building on an extended life-cycle model,this paper shows that prolonged life expectancy will cause individuals to increase their time in education but may not warrant rises in labor input.Later we show that higher improvement rate of longevity rather than initial life expectancy will promote economic growth,even we exclude the mechanism of human capital formation,and only consider growth effects of higher improvement rate of life expectancy from physical capital investment.展开更多

Based on an enterprise＇s life-cycle theory, this paper makes use of both qualitative and quantitative models to do an empirical study on measurement of the life-cycle of 1135 Chinese public companies from 1991 to 2002, both FoxPro and SAS programs are used to process data. At the end of the paper, the author comes up with a company＇s value goals and relevant competence strategies in every stage of life cycle, with the purpose to promote the Chinese public companies＇ sustainable development.展开更多
