Two ancient rounds of polyploidy in rice genome

An ancient genome duplication (PPP1) that predates divergence ofthe cereals has recently been recognized. We report here another potentially older large-scale duplication (PPP2) event that predates monocot-dicot divergence in the genome of rice(Oryza saliva L.), as inferred from the age distribution of pairs of duplicate genes based on recent genome data for rice. Our results suggest that paleopolyploidy was widespread and played an important role in the evolution of rice.     

《岁暮归南山》暑作权当属孟郊考

《岁暮归南山》素来被认为由孟浩然所作。唯韦庄《又玄集》署名孟郊。从《又玄集》成书年代与坊间孟郊已知刻本年代之比较、唐人诗互窜、“南山”争论、“不才明主弃”之辨看,此诗著作权当属孟郊。     

信息传媒时代的文艺及文艺消费之反思

处在社会转型期的中国文化形态错综复杂,而且中国业已进入传媒发达的信息社会。从文艺创作上来说,思想缺失进一步加深,创作丧失了伟大的困惑感和深渊感,部分文学创作的思维新闻化、写作的趋利性越来越明显。就作品而言,出现了很多堕落性的形式,如无心智的＂蠢文艺＂大行其道,网络文学则是网络生态产生的一种注水性文学。信息时代的文艺在多样化的同时,更应保有一种精神上的高度,从而排斥全民性的狂欢与堕落。处在传媒引导和信息包围下的受众,其生活可能失重,因为电视等媒介只是宣传的机器和娱乐的工具,消费主义意识形态本身是社会发展产生出来的悖论性结果,人们应在消费主义的洪流中认清本真之我。

Moral Education of Youths in the Information Age

In Chinese societies, moral education has always been considered the most essential component of education because the nurturing of moral persons is the prime function of schooling. The implementation of moral education has relied on the inculcation of values that reflect moral ideals. The emergence of the Information Age, with a plethora of information and ideas being disseminated instantly through informational technologies, has altered the educational landscape of the world and challenged the conventional approach to moral education. Given this context, we argue that it is important for Chinese educators to find an alternative approach to moral education that can embrace the new realities of our networked world. In this approach, lofty moral ideals should give way to simple and easily understood concepts such as respect, information and ideas in the ＂cyber world＂ should be exploited rather than shunned, and the genuine interests of children and youths should form the basis of moral education that is at once relevant and enlightening. In proposing this approach to moral education, we also assume that moral educators in Chinese societies, which include school teachers, parents, and organizers of nonformal education programs, would endeavor to understand the complex world of cyber realities and devise feasible ways to suit contextual educational needs.
