大型光学设备全寿命周期管理软件设计与实现

当前中国战略性大型光学设备需求不断增大,传统的大型设备管理模式已经逐步影响了大型设备的维护和生产,迫切需要研制一种综合的全寿命周期管理软件,将生产与维护相结合,在对系统的维护过程中记录关键数据,以求在设备再生产或者改进中发挥经验作用.为了实现上述需求,采用基于客户机/服务器(Client/Server,C/S)模式的数据库技术,通过ACCESS软件建立数据库,通过C#语言连接并访问、修改数据库,使用WPF构建用户界面,开发了软件系统,实现了预期功能.通过实际使用,验证了全寿命周期管理软件的引入提高了大型光学设备的维护效率,方便了研发人员与用户之间的沟通.     

论初中语文教学中如何培养学生的创新能力

教育心理学研究表明,学生学习漫不经心是大脑皮层处于抑制状态的表现,而敢于质疑问难,则是积极思维的表现。思是疑的前提,疑是思的发展。只有疑与思结合,才能在学习中发现问题,提出问题,最终解决问题,推动学生个体学习的进步和思维的发展。

Unraveling the interplay of review depth,review breadth,and review language style on review usefulness and review adoption

To examine whether long reviews are uniformly more useful to readers, this study utilizes the experimental design approach to investigate the interplay of review depth, review breadth, and review language style on readers’ perceived usefulness and adoption intention of online hotel reviews. Drawing on the results from two experiments, review depth is proven to exert a positive impact on readers’ review usefulness and adoption intention. The moderating role of review breadth is verified, and the positive effect of review depth on review usefulness is attenuated (accentuated) when review breadth is high (low). The moderating role of review language style is also confirmed, and the result shows longer reviews written in literal language are considered more useful to readers than those written in figurative language. Being one of the first studies examining the interplay of review content and review style on review usefulness, this study provides important theoretical and practical contributions.     

Comparing consumer-produced product reviews across multiple websites with sentiment classification

ABSTRACT

Online consumer reviews have been extensively studied. However, existing literature analyzing online consumer review data mostly relies on a single data source, resulting in potentially biased analytics conclusions. Many websites encourage consumers to post reviews of their purchased products, so that new consumers can evaluate these reviews for the same product across different websites to help them make purchasing decisions. Confusions often arise in this process, because there often exist substantial discrepancies in customer reviews across different retailers on the same product. Clarifying such confusions can help consumers reduce concerns to make up their mind for their purchases, therefore benefiting both consumers and retailers. Through text analytics and sentiment analysis, we comparatively examine the underlying patterns of online consumer reviews of three large retailers including Sears, Home Depot, and Best Buy for a same product. Afterward, we combine online consumer reviews from these large retailers and conduct an overall text analytics and sentiment analysis. The overall results are further compared with the results from individual retailers. The findings show that the sentiment of the online consumer reviews could vary substantially so relying on a single data source to make purchase decision is not a wise idea. Based on the results, we further devise a framework to comparatively examine and integrate multiple data sources for social media analytics of online consumer reviews. This study offers important managerial implications and identifies several new research directions for social media analytics.
