国内核电公众沟通研究热点及发展趋势——基于CiteSpace的知识图谱分析

文章以中国学术期刊网络出版总库(CNKI)2000—2021年发表的396篇核电公众沟通相关文献为基础,运用CiteSpace5.7R1软件,进行发文量统计、合作共现、关键词聚类、突现词探测等分析,揭示出国内核电公众沟通研究主要聚焦核电政策宣贯与技术知识普及、核电公众沟通与接受机理两大主题,沟通重心由“核事故处置”向“核应急预防”转变,沟通思路由“单向宣传”向“双向互动”转变并朝“构建核安全共同体”迈进。同时发现,国内核电公众沟通研究仍属小众领域,与我国从核大国迈向核强国的现实需求不相称,亟待更多学者广泛参与,推动学科交叉融合,增强研究系统性,提升学术影响力。     

The Design of Feature‐Limited Demonstration Software: Choosing the Right Features to Include

Today, software supports many important tasks in a variety of industries. In the specialized nature of these environments, a common problem faced by software vendors is to correctly signal the true value of a software product to the end users. For example, telecommunications equipment manufacturers design complex software for important functions like provisioning new users in the network. These software products automate various functions that would otherwise need to be done manually. In order to enable potential customers—telecommunications providers—to evaluate and recognize the full value of the product, equipment vendors often provide a free, feature‐limited version of the product to the customer. As the specific features included in the feature‐limited version influence whether the full product is purchased or not, it is essential that the features included in the feature‐limited version be selected judiciously. While the importance of identifying the best set of features has been well recognized, there has been little research to date that systematically addresses this fundamental business decision. This study fills this gap in the literature by providing an objective approach to the design of demonstration software. We illustrate the benefits of our approach through a case study involving the design of a feature‐limited demo for a wireless telecommunications equipment manufacturer.
