地址映射技术在IPv6网络中的应用

在IPv4网络向IPv6网络过渡时期,NAT—PT技术是实现两者之间通信的关键技术。但是随着IPv6的不断发展,对NAT-PT翻译网关地址转换技术也提出了更高的要求。地址映射表查找算法是NAT-PT技术的决定性因素,通过伪C代码来实现地址映射表的建立、搜索、修改、删除,此方法可以成功地将NAT—PT技术应用于IPv6网络中。     

一种基于XMLSchema的XML文档到关系数据库的映射方法

分析了P_Schema的不足,并在此基础上提出了改进算法P_Schema＋＋。将P_Schema没有提取完全的嵌套结构、被不同父元素重复引用的元素和可选元素提取出来形成新类型,从而映射为关系。为复杂XML文档的关系数据库存储提供了一种方法。     

校际协作中同步交流协调策略的设计及应用研究

基于网络的校际协作学习中,同步交流是其必不可少的一个环节,然而该环节的协作中通常会存在一些不协调的状态。文章首先分析并归纳了校际协作同步交流中的不协调状态,然后提出相应的协调策略,并对实施结果进行分析和总结。     

Mesh parameterization based on edge collapse

Parameterizations that use mesh simplification to build the base domain always adopt the vertex removal scheme. This paper applies edge collapse to constructing the base domain instead. After inducing the parameterization of the original mesh over the base domain, new algorithms map the new vertices in the simplified mesh back to the original one according to the edge transition sequence to integrate the parameterization. We present a direct way, namely edge classification, to deduce the sequence. Experimental results show that the new parameterization features considerable saving in computing complexity and maintains smoothness.     

30 years of intelligence models in management and business: A bibliometric review

The critical factors in the big data era are collection, analysis, and dissemination of information to improve an organization’s competitive position and enhance its products and services. In this scenario, it is imperative that organizations use Intelligence, which is understood as a process of gathering, analyzing, interpreting, and disseminating high-value data and information at the right time for use in the decision-making process. Earlier, the concept of Intelligence was associated with the military and national security sector; however, in present times, and as organizations evolve, Intelligence has been defined in several ways for the purposes of different applications. Given that the purpose of Intelligence is to obtain real value from data, information, and the dynamism of the organizations, the study of this discipline provides an opportunity to analyze the core trends related to data collection and processing, information management, decision-making process, and organizational capabilities. Therefore, the present study makes a conceptual analysis of the existing definitions of intelligence in the literature by quantifying the main bibliometric performance indicators, identifying the main authors and research areas, and evaluating the development of the field using SciMAT as a bibliometric analysis software.     

中国产学研合作研究的热点主题和知识演化

为明晰中国产学研合作研究领域的热点主题和知识演化,以1992—2016年CSSCI和CNKI中的1 615篇文献为分析样本,利用文献计量学与科学知识图谱方法进行分析。分析结果表明,产学研合作领域的热点涵盖合作模式、机制和影响因素;合作中的高等教育、人才培养;协同创新主体的互动关系;协同创新过程中的要素协同;绩效评价。该领域的研究主题在过去20几年发生了显著的变化,从关注合作模式到关注人才培养、教育改革、知识产权管理和利益分配等主题,再扩展到绩效评价、协同创新和创新网络等主题。     

论中国传统文化"天人合一"生命哲理对地方戏艺术的审美观照

中国传统文化精髓可谓是从现实生活立足的具有实用体征的内容与形式融和贯通的哲学思辨体系,更注重戏剧艺术特定的伦理学和美学的价值规范。可以说,"天人合一"的中华传统文化的精神"潜质",也是华夏审美文化的"中坚思维",它在人类文明历史长河中成为文化艺术精神流变的一种支配力量与文化底蕴,始终渗透于中国地方戏审美的诸多时空。因此,中国地方戏曲崇尚"天人同构"的自由、和谐、恒定、隽永的生命状态,并成为东方戏剧艺术苑囿中一朵靓丽的文化奇葩。     

从开放获取到开放科学的变化与挑战 ——基于多指标比较的文献计量分析

通过知识演化的文献计量分析,基于Web of Science核心库中关于开放获取和开放科学的913篇论文引文数据,使用CiteSpace对相关论文发表数量、涉及学科、合作网络以及研究内容聚类等知识演化研究指标展开比较分析,并基于实证研究对转变过程中的相关挑战展开理论探讨。结果表明,开放科学作为开放获取的新发展,在相关研究的内容上面存在着继承和发展,仍需要展开更多具体的实证研究以增强其实践意义。     

ORM框架的底层实现机制

ORM(Object/Relation Mapping),即对象/关系数据库映射。ORM框架就是为了解决面向对象程序设计语言与关系型数据库之间阻抗不匹配而产生的,这种框架能将业务逻辑层和持久层有效分离,使两层之间以松耦合方式衔接起来,便于代码的维护。探讨了ORM框架的实现机制。     

Combining full text and bibliometric information in mapping scientific disciplines

In the present study results of an earlier pilot study by Glenisson, Glänzel and Persson are extended on the basis of larger sets of papers. Full text analysis and traditional bibliometric methods are serially combined to improve the efficiency of the two individual methods. The text mining methodology already introduced in the pilot study is applied to the complete publication year 2003 of the journal Scientometrics. Altogether 85 documents that can be considered research articles or notes have been selected for this exercise. The outcomes confirm the main results of the pilot study, namely, that such hybrid methodology can be applied to both research evaluation and information retrieval. Nevertheless, Scientometrics documents published in 2003 cover a much broader and more heterogeneous spectrum of bibliometrics and related research than those analysed in the pilot study. A modified subject classification based on the scheme used in an earlier study by Schoepflin and Glänzel has been applied for validation purposes.
