智能生产时代下的网络安全策略研究

智能生产时代下，互联网和物联网的普遍应用、连接性的不断增加，颠覆了传统生产模式的同时，也带来了与之相匹配的网络风险和安全挑战，针对工业领域的安全事件频发，影响愈发广泛。然而网络安全策略却未能引起制造企业的足够重视与支持，网络安全人才匮乏使得制造业不断面临新的网络安全挑战。智能生产环境下的网络安全策略不容忽视，应从一开始就全面融入智能制造战略内容中。     

电力企业数字档案系统选型评价方法研究——以华能大连电厂为例

针对电力企业数字档案馆建设过程中档案系统选型难的问题。本文从电力企业的内外部环境出发,结合系统选型的三个决策目标,构建了一套适合电力企业档案系统选型的评价指标体系,并运用改进后的权衡排序法对华能大连电厂开展实例验证研究。研究表明,该方法可以很好地解决决策阶段指标权重和指标值确定的问题,而且每一步研究都有事实依据支撑。系统实施运行后的反馈结果表明,该方法选出的档案系统可以解决电力企业档案管理中存在的问题,电厂对系统和系统提供商满意度高。该研究对其它电力企业的档案系统选型也具有一定的参考价值。

数字经济是否会加剧我国税收税源背离?——来自中国城市的经验证据

运用2011—2020年275个地级市的面板数据,实证检验了数字经济发展对税收税源背离的影响。研究表明：数字经济发展和税收税源背离度呈U形关系,即当数字经济发展未达到拐点时,数字经济的发展会缓解全国范围内的税收税源背离,而当数字经济发展达到拐点后,其进一步发展会加剧全国范围内的税收税源背离。影响机制分析显示,产业结构合理化水平的提高可以缓解U形关系,但是产业结构高级化水平的提高会加剧U形关系。     

国内个人数字图书馆研究现状及国外实践扫描

个人数字图书馆的建设是与图书馆的服务理念相一致的,早在2000年,国内相关学者就对该领域进行了有益的研究,经过十余年的发展已经取得了一定的成就。国外十分重视个人数字图书馆的建设,近年来逐渐形成了各具特色的技术模式,美国的UPLIB、MyLibrary3.0系统,土耳其的MAVIS计划对我国个人数字图书馆的建设均具有很大的借鉴意义。     

iPod use and the perception of social introversion

The recent proliferation of Apple iPods begs the question: what effect does iPod use have on society and social interaction? An experimental research design was utilised to examine iPod use and degree of extroversion on the perception social interaction. At a small Christian university in the south, 105 college students participated in this study, first completing a personality inventory and then answering questions based on one of two scenarios. The first hypothesis was that participants would view iPod users as less likely to engage in social interaction. The second hypothesis was that extroverted participants would perceive iPod users as less socially engaging than would introverted participants. The results support the hypothesis that people view iPod users as less likely to engage in social interaction than non-iPod users. Participants rated iPod users as less likely to engage in social behaviours such as making eye contact. The results did not support the hypothesis that extroverted participants would view iPod users differently than introverted participants. However, this may merely illustrate that the perception of iPod users is more universal than previously thought and transcends personality characteristics.     

Institutionalising XBRL for financial reporting: resorting to regulation

By integrating and streamlining financial information within and among various organisations, eXtensible Business Reporting Language (XBRL) has been developed with a view to enhancing the efficiency, accuracy, and transparency of corporate accounting information. Taking an inter-organisational focus, this paper investigates the process of how XBRL was institutionalised. It explains and offers insights on how institutional arrangements emerge and become relevant as heterogeneous organisations consider adopting accounting innovations while evidence concerning their benefits is unavailable. The original and overall contribution of this study is that it improves current understanding of coal-face actors' perceptions, behaviours, and strategies as they interact in the organisational field and become engaged in developing accounting innovations to produce the macro-level observations documented in existing institutional theory studies.     

学术期刊优先数字出版优劣分析——以“中国知网”为例

中国知网优先数字出版具有得天独厚的人文和地理优势,巨大的品牌优势与影响力,体现了发展趋势,能形成多赢局面,为数字化出版有困难的编辑部提供了方便,顺应了集约化发展的要求;但还存在插件下载不畅、标注窗口功能单一等问题。完善优先数字出版应改革学术论文质量评价机制,改变学术期刊影响因子计算方法,加大数字化出版人才的培养力度,制定学术期刊数字化国际技术标准,加快数字化建设步伐,制定和完善相关的法律法规,加强浏览器的兼容性或开发自带的浏览器,改变“摘要”显示功能,简化标注过程。
