实施系统的心理训练提高速射运动员心理稳定性的个案研究

采用个案研究,考察了系统的心理训练对提高速射运动员心理稳定性的影响。结果表明:系统的心理训练能有效地提高速射运动员的心理稳定;心理训练必须与运动员的专项训练相结合,并且要长期有序的进行下去才可能取得良好的效果;利用目标设置和认知训练的有关理论能有效地帮助运动员的端正比赛时的心态从而促进运动员的比赛发挥。     

运动拍摄与解析技术的快速反馈研究进展

快速反馈是运动拍摄与解析技术的核心，从萌芽发展到电影拍摄、录像拍摄以至红外拍摄技术，均是围绕着快速反馈而不断创新、发展的。既有清晰图像又不须人工判读图像特征点的自动跟踪技术是运动拍摄与解析技术进一步的研究方向。

Exploring mechanisms of rapid automatized naming to arithmetic skills in Chinese primary schoolers

Rapid automatized naming (RAN) is associated with children's arithmetic performance, which is multifactorial by nature and consists of arithmetic fluency, arithmetic procedure, and word problems. Yet, it is unclear whether RAN can predict all key aspects of arithmetic skills independently and what cognitive mechanisms may explain this relation. Using a sample of Chinese primary school students (N = 170), results showed that while RAN was associated with all key aspects of arithmetic skills, the relations of RAN–arithmetic procedure and RAN–word problems may be dependent on that of RAN–arithmetic fluency. Supporting the processing speed hypothesis, results further suggested that processing speed may underlie the relation between RAN and arithmetic performance. Findings made unique contribution to understanding the effect of RAN on arithmetic performance and cognitive mechanisms that may underpin this association in the context of Chinese culture.     

社会转型加速期加强城市社区建设的意义

目前我国正处于社会转型加速期，在这一时期社会生活的各个方面，包括人们的劳动方式，生活方式，价值观念等都发生了深刻变化，带来了一系列问题，这在我国的城市社会尤为明显，加强城市社区建设将有助于解决社会转型过程中出现的某些问题，本文对此作以探讨。

对虾白斑综合症病毒囊膜蛋白Vp28基因的克隆、表达及蛋白纯化

以对虾白斑病毒DNA为模板扩增出Vp28基因,经限制性内切酶（SmaI,Not I）酶切后按正确的读码框顺序插入到pGEX-4T-2表达载体上,重组质粒转化大肠杆菌,经菌落PCR和质粒双酶切鉴定、序列测定确认,证实成功地构建了Vp28基因原核表达载体．转化菌经IPTG诱导表达,SDS-PAGE显示有与预期大小约52kD相吻合的融合蛋白带,18℃诱导24h后获得了可溶性表达的目的蛋白,采用Glutathione Sepharose 4B亲和层析对重组蛋白进行纯化,获得了纯度很高的目的蛋白．     

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.     

论高校网络思想道德环境的净化和建设

上网是大学生学习生活的重要内容,大量的良莠混杂的网络信息,对大学生的道德观念及价值判断造成了深刻影响,其消极方面集中表现为道德主体性的失落、道德失范和道德心理失衡。加强高校网络思想道德环境的净化和建设工作刻不容缓,这就要求净化校园的网络环境,保证网络信息健康文明的内容格调;教育学生自觉遵守网络法律规范,做文明网民‘鼓励和支持学校主管部门及“两课”教师创建专门网站,开辟高校网络思想教育新阵地。
