基于Web的情报信息系统的设计与实现

由于传统的公安工作缺乏技术平台支撑,在领导层决策分析时,需要进行大量手工统计,不仅工作量大而且分析过程缓慢,无法准确及时地指导工作,因此文中设计并实现了适用于公安部门的情报信息系统。以Internet中的Web服务器和Web浏览器设计为基础,介绍所开发的基于Web的情报信息系统,对其总体框架结构、主要功能等内容进行探讨和研究,构建了相应的设计资源库,并分析了实现该系统的一些关键技术。该系统的研发成功,使得公安部门能有效地实现数据资源的合理配置和利用,为公安部门提供了一个先进、实用、高效、成熟可靠的工作系统。     

JSP嵌套SQL Server Reporting Services报表

针对传统物流行业报表的制作、呈现、管理都是由报表业务人员进行操作,不能及时的将报表呈现的数据信息反馈给决策者,导致信息的延误。通过对JSP以及SQL Server Reporting Service（SSRS）的分析介绍,提出把SSRS报表嵌套在JSP中,加入到网络物流系统操作平台。基于SQL Server 2008 R2数据库以及Spring MVC框架,运用Spring注解方式与JSP技术进行系统开发,直接将SSRS报表嵌套在JSP页面供决策者分析。结果表明,JSP页面可以嵌套带有参数要求的SSRS报表,并且可以准确的读取操作SSRS报表,获得满意的嵌套效果。     

基于双线性对的k-匿名隐私保护方案研究

针对移动互联网环境下位置服务的隐私保护问题,基于双线性对性质和k-匿名的思想,提出了一个高服务质量的隐私增强方案。通过终端在欧几里得距离环形区域内均匀生成2k个虚假位置,利用位置熵、位置分散度和地图背景信息从中筛选出k-1个虚假位置,进而达到更优的k-匿名效果。通过安全性分析,本方案不仅满足隐私性、匿名性、不可伪造性等安全特性,而且能够抗查询服务追踪攻击;仿真实验表明,本方案虚假位置节点选取具有更优的均匀度,同时在假节点生成和选取效率也有所提高。     

Revisiting the two-stage choice model: an empirical study of consumer choice on brand website visits

In consumer choice behaviour literature, a two-stage choice model serves as a base theory where choice behaviour is decomposed into a consideration stage plus a choice stage. Yet, this default model has been increasingly challenged by the ‘limited consumer search’ school of thought because consumers do not necessarily review all products in a choice set before making decisions, but frequently draw on external information as mental short cuts. Methodologically, the choice behaviour in stage 1 has traditionally been latent because data that directly observe how consumers form their consideration sets by eliminating alternatives are lacking. This study continues the ‘limited consumer search’ line of reasoning and proposes an aided non-compensatory process in choice stage 1, where consumers reduce brand website alternatives by using online ratings to arrive at a consideration set. We use observed Web analytics data to unveil the stage 1 choice process and also the transition from stage 1 to stage 2, which is in need of further research based on extant literature. Lastly, we cross-validate our model with two types of websites (i.e. search vs. experience/credence) and find our model is contingent on the type of website content, where consumers’ inclination to use online ratings for decision-making varies.     

I3WSN: Industrial Intelligent Wireless Sensor Networks for indoor environments

Sensor Web Enablement (SWE) technologies have been successfully applied to a great variety of outdoor scenarios but, in practical terms, little effort has been applied for indoor environments, and even less in the field of industrial applications. This article presents an intelligent SWE application for an indoor and industrial scenario, with the aim of improving and increasing the levels of human safety. The base low-level architecture is built on top of wireless sensor networks (WSN) connected to a Sensor Observation Service (SOS). Higher layers in the architecture include services that make real time decisions based on the collected data. Both simulation and experimental results are presented. The paper shows the viability of our approach in terms of performance, scalability, modularity and safety.     

Sustainability in Web server systems

The exponential growth of Internet during the last decade leads us to make more efforts in the researching and developing of sustainable Web servers in order to decrease the global energy demand. In this paper, we cover, as a first step, a proper review of the literature related to the energy efficiency research in Web server systems to depict the state of the art to plan further contributions as more research in sustainable Web systems. We also propose and implement an energy metric that permits to establish a relation between the Quality of Service (QoS) obtained by the system and the power it consumes.     

A Study of Bruneian Corporate Customers＇ Uses of Mobile Services： An Application of Value-Based Adoption Model

This pioneering study investigates the seventy Bruneian corporate customers＇ adoption intentions towards using the mobile services. The study uses and validates the VAM （value-based adoption model） for investigating mobile service in different geographical setting contrary to the original study for Mobile Interact. The study combines four external variables such as perceived usefulness, perceived enjoyment, technicality and perceived fee with perceived value in predicting the adoption intentions of using mobile services. The study results indicate that only perceived usefulness is significant predictor of perceived values which are significant indicator of adoption intentions of using mobile services. Based on the results, some recommendations are made for the managerial implications.
