Smart cities: Advances in research—An information systems perspective

Smart cities employ information and communication technologies to improve: the quality of life for its citizens, the local economy, transport, traffic management, environment, and interaction with government. Due to the relevance of smart cities (also referred using other related terms such as Digital City, Information City, Intelligent City, Knowledge-based City, Ubiquitous City, Wired City) to various stakeholders and the benefits and challenges associated with its implementation, the concept of smart cities has attracted significant attention from researchers within multiple fields, including information systems. This study provides a valuable synthesis of the relevant literature by analysing and discussing the key findings from existing research on issues related to smart cities from an Information Systems perspective. The research analysed and discussed in this study focuses on number of aspects of smart cities: smart mobility, smart living, smart environment, smart citizens, smart government, and smart architecture as well as related technologies and concepts. The discussion also focusses on the alignment of smart cities with the UN sustainable development goals. This comprehensive review offers critical insight to the key underlying research themes within smart cities, highlighting the limitations of current developments and potential future directions.     

黄土高原社会-生态系统变化及其可持续性

在全球变化和人类活动驱动下,社会系统与生态系统均处在不断加剧的动态变化中,揭示二者之间的互馈机制是保持和增强系统弹性以及可持续性的科学基础。黄土高原地区是中国人口、资源、环境矛盾最集中的区域之一,也是黄河重要的产水区和绝大部分泥沙的来源区。合理布局黄土高原土地利用格局,协调黄土高原水土保持和黄河下游水资源利用与泥沙控制,是黄土高原地区和黄河流域可持续发展的重大需求。本文立足于国际社会-生态系统耦合研究前沿和可持续发展与生态建设的国家需求,综述了区域社会系统与生态系统的互馈机制和社会-生态系统的耦合模拟的研究进展,总结了黄土高原社会-生态系统的变化过程和驱动机制,认为发展社会-生态系统动态机制分析方法和稳态转换识别方法,建立耦合社会系统与生态系统的土地利用权衡与优化模型,是推动社会-生态系统耦合研究理论与方法创新、为黄土高原的可持续发展提供科学依据的重要途径。     

大数据下中小企业竞争情报网络信息源使用行为研究

[目的/意义] 大数据下中小企业对竞争情报网络信息源的依赖性不断上升,但存在使用障碍。本研究旨在探究大数据下企业竞争情报网络信息源的使用行为,为企业竞争情报工作提供参考。[方法/过程] 基于经典信息源分类,针对现有研究不足,创新性地将大数据下竞争情报网络信息源分为社会化媒体类、互联网公开类、互联网商务类。通过问卷调查与深度访谈方法进行研究。[结果/结论] 研究发现,社会化媒体类网络信息源的重要性增强,但传统信息源的作用不容忽视,质量是影响网络信息源使用的首要因素。     

提升大学生英语平行文本检索能力的研究

英语平行文本的阅读和借鉴不仅能在应用翻译领域帮助译者摆脱源语文化的束缚、提升译文的地道性,而且能在大学英语教学中帮助学生评估和提升语言输出质量。然而理想的英语平行文本在网络上的检索并非易事。本文针对如今大学生英语学习中信息素养能力欠缺的现状,从搜索方法、信息筛选、信息加工三个方面进行研究,旨在帮助大学生提高英语平行文本网络检索能力。     

Demystifying blockchain: A critical analysis of challenges,applications and opportunities

The blockchain is considered to be the potential driver of the digital economy. The Blockchain technology outweighs the challenges associated with the traditional transaction business governed and regulated by the third trusted party. There is a growth in the interest among the researchers, the industry, and the academia to study and leverage the potential of Blockchain. Blockchain provides a decentralized and distributed public ledger for all the participating parties. Though it seems that blockchain is a viable choice and solution for all the centralized governed and regulated transactions (in digital online space), it has potential challenges that need to be resolved; opportunities to be explored, and applications to be studied. This paper utilizes a systematic literature review to study several research endeavors made in the domain of blockchain. To further research on blockchain adoption, the paper theoretically constructs an integrated framework of the blockchain innovation adoption process in an organization considering organizational and user acceptance perspectives. This would facilitate its widespread adoption, thereby achieving sustained leadership solutions. The paper offers 23 propositions to information systems (IS)/information management (IM) scholars with respect to innovation characteristics, organizational characteristics, environmental characteristics, and user acceptance characteristics. Further, the paper explores several areas of future research and directions that can provide deep insights for overcoming challenges and for the adoption of blockchain technology.

汽车产品分销及服务管理系统的研究与开发

近年,ERP（Enterprise Resource Planning、企业资源计划）系统已在企业中大量实施,它已显著提高了企业内部信息传递效率并为企业各级管理层的决策提供了大量及时、准确的信息。由于目前的企业中实施的ERP系统大都是一些软件公司的标准产品,十分适用于采购、制造、销售、仓管、财务等标准流程。但对于企业的一些特殊流程却无法完全适应。企业的IT部门会自行开发或委托外部企业专门针对自己的一些特性需求做一些二次开发,使企业内部的流程更优化、效率更高。
