涉外星级饭店员工EHP需求分析调查研究——以武汉为例

EHP(English for Hotel Purpose)即饭店专门用途英语使用者的真实需求分析一直以来缺乏相关的实证调查和研究,导致饭店英语的教学与实际需求不一致.本文采用实地调查方法对武汉市涉外星级饭店员工的饭店英语需求分析进行了深度和广度了解,并对得出的结论进行探讨,最后提出必须依据饭店英语使用者的真实需求运用相关原则以改进饭店英语的教学水平.     

体育教育专业大学生学业自我效能感对学习自我控制力的影响

通过对内蒙古民族大学体育学院体育教育专业本科4个年级298名学生进行学业自我效能感对学习自我控制力的影响作用分析表明:学业自我效能与学习自我控制力总体之间呈中等程度极显著正相关,回归分析显示学业自我效能对学习自我控制力有直接影响作用,说明学业自我效能感越高,学习自我控制力越高.     

Inductive transfer learning for unlabeled target-domain via hybrid regularization

Recent years have witnessed an increasing interest in transfer learning. This paper deals with the classification problem that the target-domain with a different distribution from the source-domain is totally unlabeled, and aims to build an inductive model for unseen data. Firstly, we analyze the problem of class ratio drift in the previous work of transductive transfer learning, and propose to use a normalization method to move towards the desired class ratio. Furthermore, we develop a hybrid regularization framework for inductive transfer learning. It considers three factors, including the distribution geometry of the target-domain by manifold regularization, the entropy value of prediction probability by entropy regularization, and the class prior by expectation regularization. This framework is used to adapt the inductive model learnt from the source-domain to the target-domain. Finally, the experiments on the real-world text data show the effectiveness of our inductive method of transfer learning. Meanwhile, it can handle unseen test points.     

基于数据分割和集成学习的大规模SVM分类算法

支持向量机对分类问题的求解过程相当于解一个线性约束的二次规划问题,求解的变量个数与训练样本数相等,且需要计算和存储的核矩阵大小与训练样本数的平方相关.随着样本数目的增多,经典的求解二次规划问题的算法不再适用.针对大规模二分类问题,基于数据分割和集成学习策略,本文提出了一种快速支持向量机学习算法.其主要思想是:首先对数据集进行预处理,自动将正负类分别聚成若干子簇;然后对两两组合的正负子簇用SMO算法进行交叉学习,得到多个基本分类器;最后对这些基本分类器进行集成学习.在UCI的5个数据集上的实验表明,与SMO学习算法相比,这种基于数据分割的训练策略在精度几乎没有损失的情况下显著地提高了训练速度.     

A Systemic Evaluation of the State of Affairs Following the Negative Outcome of the Referendum in Cyprus Using the Structured Dialogic Design Process

This paper reports the results of the first of a series of co-laboratories organized by Cypriot peace pioneers 30 months after the negative outcome of the referendum concerning UN General Secretary’s plan for reunification of the island. The purpose of this co-laboratory was to support a diverse group of disengaged and disappointed peace pioneers and activists representing Turkish and Greek communities of Cyprus develop a shared understanding of factors contributing to the perceived widening of the gap between the two divided communities in Cyprus. The co-laboratory was organized using the structured dialogic design process (SDDP) approach within the context of a rich web-based communication environment. The root causes contributing to the widening of the gap are discussed and are also compared with those identified during a similar co-laboratory employing the Interactive Management methodology 12 years earlier.

CAI in English Language Teaching

CAI (Computer-Assisted Instruction),a kind of teaching methodology characterized by modern technology,has become a possibility in the application of modern education. CAI in ELT can provide various teaching environments and diverse study patterns which traditional teaching can not achieve. This paper mainly introduces the importance of CAI and discusses its effective use in ELT. As a newly developed technique,CAI is either a challenge or an opportunity for our teachers. If we can grasp this chance properly,...     

品味电影《变人》促进高职英语教学

欣赏英语原版电影,是英语课堂教学的一种重要补充手段。本文通过对美国影片《变人》中台词的举例和分析,结合高职英语教学,探讨了电影欣赏结合课堂教学的特点。原版电影有助于巩固学生的语言知识,深化对语法规则的理解,提高学生对学习兴趣;学生可以更深入理解英美文化,培养跨文化意识。同时,观赏电影可以提高学生对西方人性的认识。     

学习风格理论与大学英语教学

本文阐述了学习风格理论的内涵,介绍了学习风格的分类与类型。作者认为具有不同学习风格的学习者,采取的学习策略也不同,本文提出了在大学英语实践中,使教学风格与学习风格相匹配的重要性和具体实施建议。     

团队知识扩散与组织学习的匹配及其动态模型探析

对团队知识扩散的相关界定,分析影响其有效转移的主体因素、结构因素、行为因素以及环境因素。知识扩散能否在复杂、动态、模糊的情境中有效运作,很大程度上依赖于组织学习以及整体配合的灵活状态。在此基础上,构建团队知识扩散与组织学习的动态模型,为进一步的团队互动打下坚实的基础。
