    • 摘要: With the development of internationalization,English has gradually become the medium of international communication.As English is learned and used as a second language by people from different countries,nationalities and cultures,English teachers pay more and more attention to the communication and interaction of language users around the world,and World English paradigm is noticed in the classroom.This paper introduces the attitudes of different countries towards the learning and use of different English variants in the Three Circle Model,and briefly describes the formation and development of Chinglish in China,and discusses the influence of the application of World English paradigm in English teaching from both positive and negative aspects.The use of World English paradigm in English classroom is conducive to learners'development of their communicative competence and cultural identity.However,using World English paradigm will also affect teachers'ability to distinguish English variants and errors in the sense of SLA.In English classroom,teachers should choose teaching materials from the perspective of multiculturalism and receive corresponding training to avoid the risk of using World English paradigm and effectively improve students'English communication level.

    • 摘要: The collaboration tools offered by Cloud Computing have increased the need to share data and services within companies or between autonomous organizations. This has led to the deployment of community cloud infrastructures. However, several challenges will arise from this grouping of heterogeneous organizations. One of the main challenges is the management of trust between the actors of the community. Trust issues arise from the uncertainty about the quality of the resources and entities involved. The quality of a resource can be examined from a security or functional perspective. Therefore, ensuring security and monitoring the quality of resources is to ensure a high level of trust. Therefore, we propose in this paper a technique for dynamic trust management and quality monitoring of resources shared between organizations. Our approach consists, on the one hand, in evaluating the quality of resources based on quality of service measurement attributes and, on the other hand, in updating the trust values according to the information deduced from these measurements. The proposed framework is evaluated in terms of resource sharing success rate and execution time. Experimental results and comparison with TNA-SL and InterTrust models show that the framework can identify and track the behavior of malicious organizations with relatively low execution time.

    • 摘要: 目的 研究对慢性丙型肝炎(chronic hepatitis C,CHC)患者的自身抗体和丙型肝炎病毒(hepatitis virus C,HCV)进行检测,进而分析两者的相关性.方法 选取2018年12月—2019年12月在我院治疗的144例CHC患者作为研究对象.对所有CHC患者进行自身抗体检测,包括抗核抗体(antinuclear antibody,ANA)、抗可溶性肝抗原抗体(anti-soluble liver antigen antibody,SLA)、抗肝肾微粒体抗体-1(anti-hepatorenal microsomal antibody-1,LKMA-1)、抗肝细胞胞质1型抗体(anti-hepatocyte cytoplasmic type 1 antibody,LC-1)等,再检测患者的HCV-RNA,根据检测结果分析其相关性.结果 在这144例CHC患者中,98例患者的自身抗体检测结果为阳性,阳性率为68.06%(98/144);HCV-RNA检测结果中,112例患者的自身抗体检测呈阳性,阳性率为77.78%(112/144);在HCV-RNA阳性患者中,ANA阳性率高于HCV-RNA检测呈阴性的患者(P<0.05).结论 HCV-RNA检测阳性CHC患者中,其ANA的阳性率更高,提示慢性丙肝患者的自身免疫反应和丙肝病毒复制能力具有一定相关性.
