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.     

Pentadic cartography: Mapping the universe of discourse

Expressions of time have increasingly infused the rhetorical experience of post-industrial war, especially since 9/11. This essay demonstrates how these “signs of time” operate as one of three tropes: deadline/countdown, infinite/infinitesimal war, and the ticking clock. The persistence of such signs of time in public discourse can be seen as an expression of what Paul Virilio has called the “chronopolis,” a political universe textured by real-time communication technologies. The chronopolitical will exhibits certain autocratic traits at odds with democratic ideals, primarily the refashioning of citizen identity into that of the “contemporary.” The analysis here charts the autocratic rhetoric of the chronopolis as a critical democratic project.

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。     

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。
