该文以中国英语学习者口语语料库和本族语者口语语料库（老友记）为数据来源，通过语料库软件检索idea一词在两个语料库中的使用情况，重点分析idea一词的搭配及类联接，探索中国英语学习者使用该词时存在的问题及其原因，为英语词汇教学和二语习得提供一定的借鉴和思考。

This paper takes the spoken English corpus of Chinese English learners and the spoken English corpus of native speak-ers (Friends) as data sources, and through retrieving the use of the word"idea"in the two corpuses with corpus software, focuses on the collocation and colligation of the word "idea", and then ex-plores the problems existing in Chinese English learners'' use of this word and the causes, aiming to provide certain references and suggestions for English vocabulary teaching and second lan-guage acquisition.

针对云计算中多任务调度和资源分配问题，提出一种融合田口方法和差分进化算法（DEA）的改进差分进化算法（IDEA），优化云计算中多任务调度和资源分配。利用田口方法的一个正交表（OA）作为掩膜变异算子对任务进行编码，通过变异、交叉过程产生更好的后代。建立成本和时间模型，以此寻找调度方案的帕累托最优解。仿真具有5个任务和5个资源的云平台环境，以平均交叉率、分布距离、最大宽度和高维空间比率作为性能指标，将IDEA算法与DEA、NSGA-II等现有算法进行比较。实验结果表明，IDEA算法在寻找任务调度和资源分配的帕累托最优解上优于NSGA-II和DEA等算法。此外，对于不同的完工时间和任务调度成本的目标，分别列出了提出算法所寻找到的最优调度方案，能够为决策者提供很大帮助。

For the issue that multi-task scheduling and resource allocation problems in cloud computing, an Improved Dif-ferential Evolution Algorithm(IDEA)fusing Taguchi method and Differential Evolution Algorithm(DEA)is proposed. The algorithm encodes the tasks by using an Orthogonal(OA)of Taguchi method as a mask mutation operator, produces better offspring by the mutation and crossover process, and establishes a cost and time model in order to find out the Pareto optimal scheduling scheme. A cloud platform environment containing five tasks and five resource is simulated to compare IDEA algorithm with DEA, NSGA-II and other existing algorithms by using average cross rate, distribution distance, max-imum width and high-dimensional space ratio as the performance index. Experimental results show that, IDEA algorithm outperforms NSGA-II, DEA and other algorithms in finding Pareto optimal solution for task scheduling and resource alloca-tion. In addition, the optimal scheduling schemes fi

为科学地对港口物流服务商进行评估及选择,基于数据包络分析(DEA)模型,结合定性的不确定因素,提出非精确数据包络分析(IDEA)模型的港口物流服务商优选方法.该方法无需更多精确信息,并兼有一般DEA的特点,较好地解决了DEA无法处理定性因素的问题.算例分析结果表明了该方法的有效性和实用性.

To evaluate and select port logistics service suppliers scientifically, a method of IDEA model was proposed based on data envelopment analysis(DEA) model, considering the cardi-nal and imprecise factor in port vendor selection. The proposal method is more robust without demanding too much precise in-formation and keeps the characteristics of the conventional DEA model so that it can solve such a problem well that it deals with the qualitative factors in DEA model but can''t be settled there-in. Numerical example shows the effectiveness and utilities of such method.

以大陆地区31个省、市、自治区为研究对象，使用改进的DEA-IDEA模型定量地测度我国2011年农产品物流效率水平，并对各省、市、自治区农产品物流效率差异产生原因进行分析。传统模型测量结果显示，2011年东部地区的技术效率水平高于中部地区和西部地区，西部地区的技术效率水平在三大地区中最低。使用改进后DEA模型（IDEA模型）后，东部地区的技术效率水平与中部、西部地区的差距进一步扩大；而西部地区与中部地区的技术效率水平差异却有所减少。除西部地区部分省份外，全国大部分区域已不适合继续扩大农产品物流规模。同时发现农产品物流业从业人数和农产品物流总额是影响农产品物流技术效率水平的主要因素。

In this paper, with the 31 provinces, cities and autonomous regions of China as the subject, we used the improved DEA model to quantitatively measure the efficiency level of the agricultural produce logistics of China for the year 2011, then analyzed the causes for the difference in the agricultural produce logistics efficiency of them, and reached some useful conclusions and insights.

Under the background of economic globalization, the globalization of human resources management determines the success of enterprise success or failure, in a sense, human resource is the first resource of the enterprise. Cross-cultural training is the core problems in global human resource management, it can let employees quickly familiar with the company''s business and job content, understand the enterprise culture and core idea, to play a huge role in promoting enterprise development. Therefore, strengthen enterprise staff training, improve the comprehensive quality of enterprise personnel has become the urgent problems now in the process of enterprise development. Articles in samsung electronics of South Korea, for example, introduces the samsung especially cross-cultural training content, training method and training effect. And analysis of cross-cultural training impact in the global business team and establish business relationship.
