Differential Impact of Web and Mobile Interactivity on E-Retailers' Performance

This study investigates the differential impact of machine and person interactivity on both Web and mobile interfaces on e-retailers' operational and financial performance. Based on data from 463 large e-retailers in the United States and Canada, interesting findings are obtained indicating that Web machine interactivity and mobile person interactivity have significantly positive impacts on e-retailers' operational performance, whereas Web person interactivity and mobile machine interactivity do not. Furthermore, machine interactivity on a Web interface (i.e., Web machine interactivity) has a stronger impact than machine interactivity on mobile interfaces (i.e., mobile machine interactivity), and person interactivity is more influential on mobile interfaces (i.e., mobile person interactivity) than on Web interfaces (i.e., Web person interactivity). E-retailers' operational performance is found to have a significantly positive impact on e-retailers' financial performance. Overall, this study provides in-depth insights into the differential roles of machine and person interactivity on Web and mobile interfaces in affecting e-retailers' performance. Implications for research and practice as well as suggestions for future research are discussed.

消费者导向下的移动通信品牌竞争力测评模型构建探析

消费者导向下的品牌竞争力,主要体现在品牌赢得消费者与保持住消费者的能力上,对品牌竞争力的测评也主要是对这两种能力进行测评。以移动通信市场为例,从移动通信品牌的这两种能力入手,以传播、产品、价格、服务四个方面来反映品牌的核心竞争力,同时将消费者对企业的好感度作为附加竞争力,这样我们就可构建起品牌竞争力的外显型市场测量模型和品牌竞争力的要素构建型市场测量模型,利用该模型可以有效地对移动通信运营商的竞争力进行测评和比较。     

TD-SCDMA系统中一种软件集成智能天线算法

给出了一种采用信干噪比准则的、集成了预多波束天线与LMS自适应天线的软件天线方案,该方案采用开关合并方法,把软件天线输出接到最大输出信噪比的算法输出,实现算法分集.在TD-SCDMA动态模型上对提出的方法进行了仿真,结果表明,采用集成软件天线方案的误码率性能要优于单纯的预多波束天线或LMS自适应智能天线.仿真过程考虑了用户来波方向和用户到基站距离的动态变化,以及功率控制算法和系统同步过程的影响.
