Consumption and communication perspectives of IT in a developing economy

Technological innovations are important sources of competitive advantage when there is a balanced rate of adoption that helps organisations maintain or improve performance levels. This paper synthesises and builds on efforts to conceptualise the adoption and implementation of technologically induced customer services in developing countries. Its point of departure is recent advances in computer-mediated marketing environments (CMMEs). It assesses relationships between customer services and evolving technologies in the provision of services in the banking sector. Using phenomenological hermeneutics and a case study approach, we iteratively engaged with data that emerged to identify core values and community-based values. These facets were further developed into seven main issues (core values: quality, education and reach, and community-based values: efficiency, usability, control and security). The paper offers practical steps by which companies and institutions may counter these issues and the theoretical implications for wider considerations are discussed.     

小波域抑制多音干扰的扩频接收机

利用小波包理论提出了一种快速、准确地识别并且抑制多音干扰的有效方法。该方法利用小波包理论将多音干扰的各条谱线逐个定位，然后通过功率谱分析的方法来识别多音干扰的存在区间，最后将被干扰污染的区间逐个切除并反向重构接收到的信号。实验证明该方法的误比特率性能在强干扰时要优于以前的FFT域切割法。     

一种高效的无线自组网全网可靠广播协议

现有大部分的无线自组网广播协议采用最小虚拟骨干子网进行全网广播,能最小化广播的总发送次数。但是,由于未考虑无线链路的不可靠性,这些协议在实际网络中的广播效率并不高。为此,提出了一种高效的全网可靠广播协议（ENWRB）,该协议采用网络编码技术减少单跳广播的重传次数,并通过一种基于链路感知的虚拟骨干网选择算法产生更高效的广播骨干网。仿真结果表明,在确保所有节点成功接收广播消息的相同前提下,ENWRB协议的效率显著高于HCA(Hierarchical CDS-based Algorithm)协议。     

基于图像分析光学伪装效果的定量评价系统

针对传统的伪装效果评价容易受到试验条件、时间、经费等多方面限制的问题,提出了一种基于图像定量评价光学伪装效果的方法。利用AHP对颜色和形状进行权重的分析,得出颜色和形状的权重系数W1和W2,通过颜色评价系数对伪装图案与背景的图像颜色相似度进行定量评价,利用横纵比差值来对伪装图案与背景的图像形状相似度进行评价,最终得出基于图像分析光学伪装评价效果的定量评价系统。实验结果表明,该评价系统可实现对伪装图案与背景的颜色和形状相似程度的定量评价。     

基于物联网技术平台的O2O商业模式研究

在国家大力推进产业结构调整、信息化的压力下,物联网技术和O2O商业模式作为信息时代的新型生产力,在国内的普及率并不高。本文运用案例分析的方法通过研究大学生创业项目引入O2O商业模式的概念,并与物联网技术有机结合,把握两者之间优势互补的关系,提出两者创新应用,同时从商业模式构成要素的角度对该模式进行系统、深入分析,为中国现代农业信息化建设和结构调整提供了新思路。     

Beyond concern: socio-demographic and attitudinal influences on privacy and disclosure choices

ABSTRACT

The co-option of consumers as unwilling agents in their own surveillance has enabled significant abuses of consumer privacy. Previous studies have largely used privacy concern as a proxy for overall privacy attitudes. In this study, we implement a choice experiment in combination with measures adapted from Communication Privacy Management theory to enable a broader exploration of the influences of privacy attitudes by contextualising privacy as a negotiation about accessibility over contextual boundaries. Key findings suggest individuals’ social media disclosure decisions are influenced at least in part by their privacy attitudes, particularly with respect to information categories which may cue other personal information. Findings are also presented on consumers’ willingness to pay for privacy, with implications for alternative revenue streams not built on consumer surveillance.     

When open-mindedness lowers product evaluations: Influencers to consumers’ response to religious cues in advertising

Prior research has examined response to Christian religious cues used in secular marketing messages but has inadequately explored the underlying reasons for such response as well as why religious cues may negatively influence product evaluations. These limitations are addressed in this research work through three studies utilizing religious cues. In Studies 1a and 1b, ads with a Christian or Muslim religious cue (no religious cue) were found to produce lower (higher) product evaluations. Studies 2–3 then examined why religious cues in ads can produce lower product evaluations to show that open-mindedness moderated this effect (Study 2), and priming open-mindedness also influenced this effect (Study 3). Most interestingly, open-minded consumers were more negative toward religious cues in marketing communications than close-minded consumers, and priming open-mindedness magnified this effect. These novel effects are discussed in relation to the literature on open-mindedness and value-based consumption. Additionally, implications for research and practice are discussed.     

Can Pokémon GO catch brands? The fit effect of game characters and brands on efficacy of brand communications

Given the recent popularity of augmented reality (AR) games, such as Pokémon GO, this study explores the congruence effect of game characters and brands on brand evaluations and the underlying mechanisms of the effect. Prior gaming experience and motivations are taken into account. An experiment reveals that inexperienced gamers are likely to have more favorable evaluations of the target brands when the images of game characters match the brand images, whereas these effects disappear for experienced gamers. Furthermore, the research demonstrates that experienced gamers are more likely to hold game-specific motivations than the inexperienced, while inexperienced gamers are motivated more by social interaction for playing AR games. Lastly, a mediation analysis reveals that social interaction-related motivation mediates inexperienced gamers’ preference of character–brand congruence. This study sheds light upon how AR games can be utilized by brand communicators.     

基于无线生理传感器与虚拟现实技术的复愈性环境注意力恢复作用研究

基于卡普兰复愈性环境理论，运用脑机接口设备、智能腕带传感器等无线生理指标检测技术，测试大学生被试人群在沉浸式虚拟现实(VR)情境下，对4种复愈性环境及城市环境在注意力恢复和压力减轻方面的反应及其作用强度，获得被试在不同环境中脑电、心率、肌电的客观生理数据。采用非参数统计方法R语言对数据进行分析。结果显示，多数被试在复愈性环境中较城市环境表现出更好的注意力恢复效果。其中具有逃离性和迷人性特征的自然环境，复愈效果最为明显；在虚拟现实环境中，观赏城市环境图片也具有一定的复愈效果。
