基于共轭分析的网络对抗效能评估

本文为了探讨影响网络对抗效能评估的众多因素,利用可拓学中的共轭分析进行研究。介绍了共轭分析原理中的虚实、软硬、潜显和负正这四对概念,并利用这四对概念分别从网络对抗系统的物质性、系统性、动态性和对立性这四个方面分析影响其效能的各种因素,为网络对抗效能评估提供了新的思路。

三峡库区资源开发及可持续发展管见

三峡水库位于长江上游下段,受回水影响的水库淹没区和移民安置涉及的县市称为库区。三峡库区属我国经济发展水平低的连片贫困地区之一。90年代以来,随着三峡工程的兴建,库区资源开发和经济发展速度明显加快,但也面临着许多挑战和发展中的经济、社会问题。对此,提出了自己的观点。     

环境规制与行业异质性对制造业企业技术创新的影响——基于我国沿海与内陆地区的比较

基于行业异质性视角,以2010年—2015年我国省级制造业规模以上企业为样本,将环境规制划分为正式型与非正式型两类,对比分析了沿海与内陆地区环境规制、行业异质性对企业技术创新影响的差异。研究发现：(1)从制造业全行业来看,正式型环境规制对技术创新的影响作用在沿海与内陆地区均显著为正;非正式型环境规制对技术创新的影响作用在沿海地区显著为正,在内陆地区作用不显著;环境规制强度对技术创新的影响作用在沿海地区显著为负,在内陆地区显著为正。(2)环境规制对高污染行业的技术创新作用在沿海地区显著为正,在内陆地区显著为负。(3)环境规制对高搬迁成本行业的技术创新作用在沿海地区显著为正,在内陆地区显著为负。     

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.

“有效性”视域下华语教学若干问题的思考

华语教学是特殊的二语教学,其最终目的是培养华裔青少年具有在现实生活中自由运用华语进行交际的语言能力。但当前,一些认识因素、教学因素和环境因素严重制约着华语教学的“有效性”,只有实现华语教学目标的综合化、教学过程的交际动态化、教学方法的多元化和教学环境营造的多样化,才是促进华语教学的健康发展、提高华语教学“有效性”的必然选择。     

刍议环境权的创设

环境权是一项新兴的、正处于发展中的重要权利,其产生具有深刻的背景和动因。从法律上创设环境权,一方面适应了现实社会的普遍需求;另一方面解决了环境利益与传统权利体系难以协调的矛盾,具有十分重要的现实意义。在现有的社会历史条件下,对环境权的主体、客体和内容应作合理界定。从法律上创设环境权的基本途径是环境权的宪法化。     

Teaching and evaluating instructor effectiveness using the instructor effectiveness questionnaire and the instructor effectiveness check sheet combination

Abstract

This article describes the use of two linked instruments, the Instructor Effectiveness Check Sheet (IEC) and Instructor Effectiveness Questionnaire (IEQ). The use of an evaluation instrument during a course can enable improvements to be made — even with experienced instructors. Detail can be taken from the IEC and IEQ to find obvious and not so obvious needed changes and attention to individuals in the group. The article gives an example where the instruments were used to teach instructors about different pedagogical constructs, describes further research using the instruments at the Nantahala Outdoor Center, USA, and describes a case study on a wilderness education group that illustrated improvement in effective teaching.
