Language corpuses offer great convenience to language researches. Prefabricated chunks are a great help for learners to achieve oral English fluency. With the help of computer software, chunks in SECCL are categorized. The conclusion is in the process of chunks acquiring, emphasis should be on content-related chunks, especially specific topic-related ones. One effective way to gain topic-related chunks is to build topic-related English corpus of native speakers.展开更多

These conditions have been forced the movement to adopt themselves to this process vitally. As of year 2007, there are 26 several types of cooperatives with 90.086 unit cooperatives which have total number of 8,561.618 partners that are all dependent to Turkish cooperative association as well as Ministry of Industry and Commerce. In this study, the web sites of Turkish agricultural cooperatives were examined in terms of their contents. Also, it is tried to find out the sufficiency level of their electronic marketing activities.

The creation of such standards by the IASB aims at achieving harmonization of accounting practices among countries. The objective of this research is to show that in accordance with the expectations of international organizations, the adoption of IAS-IFRS increases the information content of financial statements and also to identify the key accounting variables that have been affected by this adoption. This article used a sample of year observations of 150 French firms which have adopted IAS-IFRS since 2005 as data to study the association relationship between accounting variables and stock returns before and after the adoption of IASs. The findings of this paper show that the application of IAS-IFRS as accounting standards increases the information content of accounting numbers. Dividends, long-term debts, equity, and revenue variables are most correlated with stock returns. Their information content has reached 80% after the adoption, while it was 30% before.展开更多

Although there are some technological instruments structuring this work, the methods that have been used must have improvement to a better use. In this sense, IA （information architecture）, as a process that helps users to manage and find information, can collaborate with the organization of this assets allowing the best identification and categorization of information, as well as providing improvements in the website navigation in Intranets and Internet. This article introduces part of a research that deals with the use of IA for developing and structuring the project of Dataprev about the content management for Brazilian social security system.展开更多

Mathematics curriculum standards clearly stated： the design and implementation of the mathematics curriculum should pay attention to the use of modern information technology, particularly to fully consider the impact on mathematics learning content and methods, and to provide students with a more vigorous development of rich learning resources, the modem information technology as a powerful tool for students to learn math and problem-solving, working to change the way students learn, students willing and more energy into reality, exploratory math activities.展开更多

However, the underlying mecha- nism of MHC evolution is still not fully understood. In this study, we investigated genetic variation of three classical MHC class I genes in the giant panda （Ailuropoda mela- noleuca） and tested for selection effect and recombination event across exonic and intronic sequences to understand maintenance mechanism of polymorphism at Aime-MHC class I genes. In total, we isolated 21 MHC class I haplotypes （exon 2-intron 2-exon 3） from 46 captive giant pandas, of which eight were for Aime-C, seven for Aime-I and six for Aime-L; however, we only identified six unique sequences from these haplotypes. The subsequent maximum-likeli- hood and Chi-square analyses both detected evidence of recombination acting on the 21 haplotypes. These results indicate that the giant panda still retains a relatively high adaptive variation at Aime-MHC-I genes, and that the intronic segments have been homogenized along evolu- tionary time by recombination and subsequent genetic drift.We calculated nucleotide substitution rates of the antigen- binding regions （exons 2 and 3） and the noncoding intron 2, and found two pieces of evidence supporting the presence of balancing selection in the giant panda： an excess of nonsynonymous over synonymous substitutions at the antigen-binding sites, and an obviously higher synonymous substitutions in the exons than nucleotide substitutions in the intron. Thus, this study reveals that balancing selection and recombination together shape the diversity pattern at Aime- MHC-I loci of the giant panda.展开更多
