Computer and Information Science , 2012, DOI: 10.5539/cis.v5n4p77
Abstract: The paper puts a “cloud” learning platform mode. In order to improve the quality of education and teaching and solve the problems such as single teaching systems, the gap between classroom teaching and online teaching and less interaction between the teacher and students and so on. First, force on the application of cloud computing, cloud learning and cloud platforms, we analysis and compare to characteristics of the traditional learning platform, and propose a method that based on the B-learning thinking for the cloud learning platform. Then we give an instance of practice application and it proves that the establishment of cloud study platform has improved the efficiency of the teachers’ classroom, the students’ independent learning, teacher-student interaction, and so on. It is of great significance for promoting the teaching techniques of innovation
An Application Research on Configuration Software System Platform Based on Component Technology
Chao Xu,Hongmei Ge
Computer and Information Science , 2012, DOI: 10.5539/cis.v5n3p76
Abstract: This paper proposes a component based configuration software platform model that aims to develop the application system meeting different demands and build a high-quality software integration system. The model separates system logic description from system implementation and reinforces logic extensibility and reusability using the configuration idea of industrial controlling automation for reference on the base of traditional software developing method. From the effects of the application for the real projects, we can see that the method can reduce the system implementation cost and reinforce the software credibility with better maneuverability and reusability.

Genetic Diversity and Linkage Disequilibrium in Chinese Bread Wheat (Triticum aestivum L.) Revealed by SSR Markers
Chenyang Hao,Lanfen Wang,Hongmei Ge,Yuchen Dong,Xueyong Zhang
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0017279
Abstract: Two hundred and fifty bread wheat lines, mainly Chinese mini core accessions, were assayed for polymorphism and linkage disequilibrium (LD) based on 512 whole-genome microsatellite loci representing a mean marker density of 5.1 cM. A total of 6,724 alleles ranging from 1 to 49 per locus were identified in all collections. The mean PIC value was 0.650, ranging from 0 to 0.965. Population structure and principal coordinate analysis revealed that landraces and modern varieties were two relatively independent genetic sub-groups. Landraces had a higher allelic diversity than modern varieties with respect to both genomes and chromosomes in terms of total number of alleles and allelic richness. 3,833 (57.0%) and 2,788 (41.5%) rare alleles with frequencies of <5% were found in the landrace and modern variety gene pools, respectively, indicating greater numbers of rare variants, or likely new alleles, in landraces. Analysis of molecular variance (AMOVA) showed that A genome had the largest genetic differentiation and D genome the lowest. In contrast to genetic diversity, modern varieties displayed a wider average LD decay across the whole genome for locus pairs with r2>0.05 (P<0.001) than the landraces. Mean LD decay distance for the landraces at the whole genome level was <5 cM, while a higher LD decay distance of 5–10 cM in modern varieties. LD decay distances were also somewhat different for each of the 21 chromosomes, being higher for most of the chromosomes in modern varieties (<5~25 cM) compared to landraces (<5~15 cM), presumably indicating the influences of domestication and breeding. This study facilitates predicting the marker density required to effectively associate genotypes with traits in Chinese wheat genetic resources.
Identifying Loci Influencing 1,000-Kernel Weight in Wheat by Microsatellite Screening for Evidence of Selection during Breeding
Lanfen Wang, Hongmei Ge, Chenyang Hao, Yushen Dong, Xueyong Zhang
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0029432
Abstract: Chinese wheat mini core collection (262 accessions) was genotyped at 531 microsatellite loci representing a mean marker density of 5.1 cM. One-thousand-kernel weights (TKW) of lines were measured in five trials (three environments in four growing seasons). Structure analysis based on 42 unlinked SSR loci indicated that the materials formed two sub-populations, viz., landraces and modern varieties. A large difference in TKW (7.08 g, P<0.001) was found between the two sub-groups. Therefore, TKW is a major yield component that was improved in the past 6 decades; it increased from a mean 31.5 g in the 1940s to 44.64 g in the 2000s, representing a 2.19 g increase in each decade. Analyses based on a mixed linear model (MLM), population structure (Q) and relative kinship (K) revealed 22 SSR loci that were significantly associated with mean TKW (MTKW) of the five trials estimated by the best linear unbiased predictor (BLUP) method. They were mainly distributed on chromosomes of homoeologous groups 1, 2, 3, 5 and 7. Six loci, cfa2234-3A, gwm156-3B, barc56-5A, gwm234-5B, wmc17-7A and cfa2257-7A individually explained more than 11.84% of the total phenotypic variation. Favored alleles for breeding at the 22 loci were inferred according to their estimated effects on MTKW based on mean difference of varieties grouped by genotypes. Statistical simulation showed that these favored alleles have additive genetic effects. Frequency changes of alleles at loci associated with TKW are much more dramatic than those at neutral loci between the sub-groups. The numbers of favored alleles in modern varieties indicate there is still considerable genetic potential for their use as markers for genome selection of TKW in wheat breeding. Alleles that can be used globally to increase TKW were inferred according to their distribution by latitude and frequency of changes between landraces and the modern varieties.
Response of phytoliths in Leymus chinensis to the simulation of elevated global CO2 concentrations in Songnen Grassland, China
Yong Ge,DongMei Jie,JiXun Guo,HongMei Liu,LianXuan Shi
Chinese Science Bulletin , 2010, DOI: 10.1007/s11434-010-4123-2
Abstract: Measuring the response of terrestrial ecosystems to elevated CO2 concentrations is very important for understanding the effects of global change. In this study, OTC (open top chambers) were used to simulate elevated CO2 concentrations in the Songnen Grassland. As well, phytoliths in Leymus chinensis were extracted to study the relationships between phytoliths and CO2 concentration. The results show the rondel is abundant in Leymus chinensis, while the trapeziform polylobate is rare. When phytolith production is increased, the rondel phytoliths grow bigger and the proportions of the different phytolith types changes under high CO2 concentration. These types include elongate hollow, acicular hair cell, square and laminate and are only observed in samples grown under high CO2 concentrations. All this evidence demonstrates that phytoliths in Leymus chinensis are sensitive to CO2 concentration, and indicate that phytolith analysis may have potential use in the study of global change, identifying different ecotypes of Leymus chinensis and for the reconstruction of paleoatmospheric CO2 concentrations.

Looking Back at the New Knowledge Bases of EFL Teacher Education  [PDF]
Hongmei Zhu
Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.412106
Abstract: This article discusses the trend of reconceptualizing EFL teachers’ knowledge base to avoid the separation between theory and practice, which is in particular reflected on the establishment of some new EFL teachers’ knowledge domains. However, the horizontal categorizing approaches of teachers’ knowledge establish another gap between theory and practice and the hierarchical approach formulates so much abstract knowledge for teachers. The construct of knowledge of EFL classroom interaction is a pilot inquiry to create an interface between “theory knowledge” and “practice knowledge” from the teachers’ needs. In the end of the article, a rough knowledge framework is constructed for EFL classroom interaction on teachers’ needs.

Learning Opportunity and EFL Teachers’ Questions  [PDF]
Hongmei Zhu
Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.43027
Abstract: As postmethod EFL teaching method was proposed in 1999, ideas on teaching and learning be-came unthinkably various and dynamic. The views on teachers’ questions also changed a lot in postmethod period. The term of learning opportunity bridged teaching and learning in this situation. This article aims to explore the way that an expert teacher, an experienced teacher and a novice teacher provide learning opportunities for the students in their question-answer sequences. A CA approach is used to analyze three teachers’ questions based on four different students’ first responses: Right Answer, Partly Right Answer, Incomplete Answer and Refusal Answer. The results suggest that the expert teacher can provide more learning opportunities by strengthening students’ identities, extending students’ contributions, attracting students’ involvement and there is an insignificant relation between the type of questions and learning opportunities. It is suggested that EFL teachers can be more aware of the local and dynamic teaching context and promote more negotiation of meaning and students’ involvement.
