Space- and time-efficient approach for virtual machine provisioning

As a new promising paradigm, cloud computing can make good use of economics of scale and elastically deliver almost any IT related services on demand. Nevertheless, one of the key problems remaining in cloud computing is related to virtual machine images, which require a great amount of space/time to reposit/provision, especially with diverse requests from thousands of users simultaneously. In this paper, by using the splitting and eliminating redundant data techniques, a space and time efficient approach for virtual machines is proposed. The experiments demonstrate that, compared with existing solutions, our approach can conserve more disk space and speed up the provisioning of virtual machines.

无限接近原著为前提的译者主体性--感悟于结构主义与解构主义的特点

结构主义在揭示语言内部客观规律的同时忽视了译者的主体性;解构主义在否定文本终极意义的同时夸大了译者的主体性.所以,运用矛盾的对立统一规律辩证地分析二者的显著特点,探索科学合理的建构理论.把"无限接近原著为前提的译者主体性"作为翻译学的指导思想和理论基础.     

我国融资租赁立法若干问题的探讨

Differential prospective relationships of social-oriented and individual-oriented achievement motivations with achievement goals and affective wellbeing: A 1-year follow-up study

This study aimed to investigate the differential prospective relationships of social-oriented achievement motivation (SOAM) and individual-oriented achievement motivation (IOAM) with student's adoption of specific achievement goals and their affective wellbeing (AWB). A total of 332 Chinese university students (M_age = 19.139; Female = 75%) voluntarily participated in the baseline and the 1-year follow-up surveys of this study. The factor score path analysis results showed statistically significant positive paths from SOAM and IOAM at baseline to performance goals and mastery goals, respectively, at follow-up. Moreover, a statistically significant positive path was found from SOAM at baseline to negative affective experiences, at follow-up, and no association was found between IOAM and AWB, after controlling for achievement goals. The findings suggest the usefulness of raising educators' and parents' awareness regarding the double-edged sword of utilizing socially valued motives to promote performance approach goals in individuals because such values potentially lowering their psychological wellbeing.     

长期股权投资收益确认问题的探讨

长期股权投资收益的核算方法有成本法和权益法两种。在权益法下应根据投资比例和被投资企业的盈利确认投资收益，但是，这样处理不符合资产的定义和会计准则的基本要求，也是通货膨胀产生的重要原因。因此，在反映双方内在经济利益关系的基础上，有必要按收付实现制核算投资收益。     

建设现代编辑心理学刍议

现代编辑心理学是把普通心理学、现代心理学的有关理论与编辑工作的具体实践结合起来,主要探讨编辑活动中认识主体各自的心理特征、心理现象、心理机制及其他们之间相互的心理感应规律与心理活动规律的一门学科.它是新兴的边缘交叉学科,也是一门应用学科;它的特点是具有交叉性、独特性、创造性、实践性、探索性.研究的原则是客观性、反映论、发展性、系统性;研究的方法是观察法、实验法、心理测验法、调查研究法;研究的意义是有助于推动编辑学和心理学自身的发展,有助于提高编辑队伍的素质,培养编辑健全的人格.     

The Use and Misuse of Standardized Testing: A Whiteheadian Point of View

First an overview is given about the actual national and international situation concerning standardized testing. Then two major reasons are presented why accountability systems based on standardized testing have become so widespread: (a) the missing validity and reliability of teachers’ assessment of students’ achievement, and (b) the important role standardized testing plays for out-put management in educational systems.On the basis of these considerations Alfred North Whitehead’s critical remarks on external standardized testing are presented. Whitehead’s main point is that external standardized testing limits the freedom of teachers to adapt to the complex, situation specific circumstances in order to obtain a maximum of the creative learning process for students who are conceived as specialists. Instead external testings lead to “teaching to the test.” As a consequence, the attitude of creative, adventurous exploration is undermined and substituted by simple pattern recognition, narrow visions, and even boredom. Finally, the question is raised whether there is any possibility of developing a measurement tool which on the one side meets scientific test criteria, and on the other side is still flexible enough to do justice to needs of individual schools – which according to Whitehead are the essential educational unit – and not vice versa, as it is the case at present with external standardized testing. That such a flexible approach to evaluation is possible is demonstrated by the presentation of the basic ideas of the MSS (Module Approach to Self-Evaluation of School Development Projects) which has been developed and examined in ten schools by the author and his collaborators.     

One-to-One Computing and Student Achievement in Ohio High Schools

This study explores the impact of one-to-one computing on student achievement in Ohio high schools as measured by performance on the Ohio Graduation Test (OGT). The sample included 24 treatment schools that were individually paired with a similar control school. An interrupted time series methodology was deployed to examine OGT data over a period of 5 to 8 years. Overall student performance and content-specific achievement in math, reading, science, social studies, and writing were not significantly affected by the introduction of 1:1 computing. Treatment schools using a netbook device produced the greatest overall change in scores.
