Are boys left behind? The evolution of the gender achievement gap in Beijing's middle schools     

Fang Lai 《Economics of Education Review》2010

Using one cohort of 7235 middle school students in Beijing, China, we examined the evolution of the gender achievement gap in middle school. Our study found a more significant female dominance than in U.S. studies: even though boys gradually caught up during middle school, especially in Math and Science, and the gender achievement gap decreased over the distribution of test scores, girls outperformed boys throughout primary and middle school and in each quartile of the performance distribution. As well, girls had a more positive school experience than boys, and boys had a higher dropout rate by the end of middle school. Despite significant gender differences in various important characteristics that have explained the gender achievement gap in the U.S., in our study, primary school test scores seemed to be the only significant source of the gender achievement gap at the end of middle school, indicating the importance of early intervention.  相似文献   

Beyond English Literature A Level: The silence of the seminar?     

Gary Snapper 《English in Education》2009,43(3):192-210

This paper presents data from a doctoral study of the relationships between A Level English Literature and university English, a study which examines the experiences of one class of first year university English students. It argues that, whilst the socio-cultural emphases of literary study in the university have the potential to offer a great deal to students, full attention to the interplay between curriculum and pedagogy, and an understanding of the values and assumptions which students and lecturers bring to the literature classroom, are vital if students are to be genuinely engaged in the theoretical aspects of the discipline.  相似文献

十六大以来中国农村改革进程的基本判断与前瞻     

张新光 《临沧师范高等专科学校学报》2006,(1)

十六大以来,中国新一轮农村改革发展的一条主线是"多予、少取、放活"。目前,农村税费改革已取得了阶段性的巨大成功,国民收入分配结构和财政支出结构正向农村地区倾斜,"三农"问题初步得到了缓解,我国在总体上进入到了"后农业税时代"和"工业反哺农业、城市支持农村"新的发展阶段。下一步深化农村改革的重点、难点是,逐步消除城乡二元体制对经济社会协调发展所造成的瓶颈制约,从根本上解决"三农"问题的深层次矛盾和体制性障碍;最大的突破口选择是加快推进农村综合配套改革,进一步做好"放活"这篇大文章,充分发挥9亿农民的市场主体地位和作用,激发农民自我发展和自我积累的巨大潜能,不断提高和增强农业和农村经济发展的内部活力。这是我国在本世纪头20年实现全面建设小康社会目标的根本途径。  相似文献

Characteristics of faecal bacterial flora and volatile fatty acids in Min pig,Landrace pig,and Yorkshire pig     

《Electronic Journal of Biotechnology》2021

BackgroundIn order to study the influence of long-term growth process and evolution environment on intestinal bacteria of different breeds, the intestinal bacteria and volatile fatty acids among the faeces of Min, Landrace and Yorkshire pigs were analysed by Illumina high-throughput sequencing of the 16S-rDNA and gas chromatography.ResultsThe shared core microbiota of Landrace, Yorkshire and Min pig were 1273, accounting for 69.56% of total abundance of organisms. The proportion of Firmicutes in Min pig faeces (57.89%) was significantly higher than that in Landrace and Yorkshire pig faeces (47.01% and 46.40%, respectively) (P < 0.05), but that of Bacteroidetes was exactly opposite. Moreover, Min pig presented more highly efficient membrane transport, environmental adaptation, carbohydrate transport, and metabolism than Yorkshire pig (P < 0.05). The acetic acid/total volatile fatty acid ratio in Min pig was significantly higher than that in Landrace pig (P < 0.05), and the isobutyric acid/ total volatile fatty acid ratio in Min pig was significantly larger than that in Yorkshire pig (P < 0.05). Furthermore, the content of branched chain volatile fatty acids in Min pig was significantly higher than that in Yorkshire pig (P < 0.05).ConclusionsThis study demonstrated that Min pig, as an excellent breed in the cold area of China, possessed special intestinal floral structure compared to the imported pigs in order to satisfy their physiological and metabolic demands, which may influence their characteristics such as resistance to cold, diseases, and crude feeding, and the ability to deposit intramuscular fat.How to cite: Yang Y, Sun C, Li F, et al.
