Consumer Adoption of Mobile Internet Services: An Exploratory Study

This study provides a framework that captures the antecedents of mobile internet adoption and the willingness to pay for such service. The theory of reasoned action and components of a theory of innovation adoption were integrated into a research model of consumer adoption of the mobile internet. The hypothesized model included service quality perceptions (fixed internet and mobile technology service), beliefs about mobile internet, and individual difference variables to explain intention to adopt mobile internet. An online questionnaire was used to gather data. The results showed that beliefs and quality perceptions play a significant role in influencing intentions to adopt mobile internet. In particular, beliefs about mobile internet are positively related to the adoption; quality perceptions of fixed internet are found significant to negatively influence adoption intentions, but positively relate to willingness to pay for using mobile internet. Mobile service usage, and peer influence are found non-significant to influence adoption intentions. Fixed internet usage was found negatively affect adoption intentions. Computer skills, knowledge of mobile internet and career mobility are all found positively related to the adoption. In addition, innovation driven consumers are more likely to adopt mobile internet, and intention to adopt plays an important role in shaping actual mobile internet use. Implications of results and directions for future research are examined.     

Prevalence and attitude of university students towards mobile phone use while driving in Jeddah,Saudi Arabia

ABSTRACT

This study aimed to investigate the prevalence and attitude of university students towards mobile phone use while driving. The present study was conducted at King Abdulaziz University, Jeddah, Saudi Arabia. Five hundred and ninety-three participants were recruited for this study. Attitude, consequences and their involvement in various reckless behaviours pertaining to the use of mobile phone while driving were checked by a questionnaire. Overall, the majority of the respondents (90%) use a mobile phone while driving. About half of the participants had experienced consequences regarding texting while driving and had engaged in reckless behaviour. The majority of the students of Faculty of Medicine, Engineering Sciences, Earth Sciences, Administration and Economics and Orientation Classes were more frequently texting while driving (p < .001). The unmarried students were more often texting while driving as compared to married (p < .001). Overall, the majority of the respondents use the mobile phone while driving.     

Mobile Shoppers: Types,Drivers, and Impediments

The technology adoption of mobile commerce has frequently been studied by considering the extended technology acceptance model (TAM). However, the role of the perceived drivers and impediments affecting potential mobile shoppers' acceptance has been scarcely analyzed. This article highlights: (1) the typology of potential m-shoppers described by their reasons for, and perceived impediments to, mobile shopping and (2) the possible differences in the extended TAM in the resulting categories. In order to do so, we advance a single hypothesis about moderation of the m-shopper type on the relationships presented in the extended TAM. The study was conducted in Spain, a country with significant current and forecasted use of mobile shopping. Data from 476 Spanish mobile phone users were analyzed. The use of latent class cluster allowed us to identify three types of mobile shoppers that show different profiles based on their perception about drivers and impediments. Differences in the extended TAM relations across the clusters were identified using the multigroup approach of structural equation models. The results show support for the moderation effect, providing valuable information for practitioners to understand how consumers develop mobile shopping intentions, which is necessary to implement effective marketing strategies.     

Mobile Commerce

Abstract

To Business-to-Consumer (B2C) companies, finding convenient and secure payment methods is crucial. While the most popular payment method in the United States is the credit card, the common methods in Japan are cash on delivery, transfer of payment into bank accounts, and postal money order. The paper presents such issues as why credit card payments have not become the mainstream payment method in Japan, the current situation of other payment methods, and the future mobile trend.     

Extracting Value from the Supply Chain with Mobile Technologies

Abstract

This paper attempts to alleviate some of the current confusion about the capabilities of mobile technologies in the context of the enterprise and its supply chain. Unique features that differentiate m-business from e-business are explored. We highlight the sources of value creation of m-business applications by extending a theoretical framework proposed by Amit and Zott (2001), and we suggest potential areas in which mobile technologies appear exceptionally suited to produce cost savings or opportunities for differentiation of product or services. Two dimensions of value creation stand out: efficiency and novelty.     

New Technology Adoption,Business Strategy and Government Involvement: The Case of Mobile Commerce

SUMMARY

This research focuses on understanding how business organizations are likely to adopt mobile commerce (m-commerce) technology. Mobile commerce adoption represents a complex process that draws in variables external to the firm such as the environment in which the business operates and the government involvement, as well as variables internal to the company such as its business strategy and its organizational culture. A model is formulated and several research propositions are offered. They will help understand the mobile commerce applications adoption process. Implications of this model and further research avenues are discussed.     

低轨LTE卫星随机接入前导设计及检测算法研究

针对低轨卫星环境中的较广波束覆盖范围和较大多普勒频移的特点,研究了能够应用于低轨LTE（Long Term Evolution）卫星移动通信中的随机接入前导及其检测算法。首先,提出多根长序列（MRLS）,该序列通过级联多个根序列号不同的短ZC（Zadoff-Chu）根序列构建,可以支持一步定时提前估计;其次,提出一种基于MRLS的随机接入前导检测算法,该算法通过相邻短ZC根序列的共轭相乘产生多个检测序列,再与多个待检序列进行联合差分相关检测,克服了整数倍和小数倍子载波间隔的多普勒频移的影响。仿真结果表明,利用MRLS序列,所提算法对载波频率偏移具有很好的鲁棒性,适用于基于LTE的低轨卫星移动通信系统。     

‘Regrettable-escapism’ the negative effects of mobile app use: A retail perspective

Despite the enhanced shopping opportunities that mobile devices offer to consumers, there is a fine line between consumers enjoying the mobile shopping process and them regretting the time spent involved in it. Through the lens of Uses and Gratifications Theory (U>) and drawing on Flow Theory, this study aims to understand the effects of consumers' interactions with mobile shopping apps on their intention to reuse the app in the future, loyalty towards the brand and brand reputation. Study 1, through a questionnaire (n = 1024), provides insight into the positive and negative relationships between Utilitarian and Hedonic gratifications on intentions to reuse a retailer's mobile app, loyalty towards the b,rand and the brand's reputation. Through undertaking 24 in-depth interviews, Study 2 provides deeper insight into these relationships to uncover the complex nature of the negative effects of escapism. Findings demonstrate that the addictive nature of retailers' shopping apps lead to regrettable escapism. The flow state of mind experienced during escapism, becoming engrossed and notions of time-distortion, leave consumers with feelings of guilt and frustration due to the perceived wasted time spent on the retailer's app. Accordingly, this study advances theoretical understanding of escapism and its negative effects with ubiquitous, portable smartphones. The research provides implications for retailers and policy makers, while offering avenues for future research.

基于LMS估计的卫星移动通信定时同步优化

针对采用长期演进（LTE）通信标准的地球静止轨道（GEO）卫星移动通信系统上行定时误差会影响单载波频分多址技术正交性的问题,在LMS线性估计算法的基础上提出了一种适用于大时延环境下单载波频分多址定时同步优化方法。该方法对用户与卫星之间传输时延的变化进行估计,通过闭环控制补偿减小上行定时误差。仿真表明：该方法在使用LTE标准帧结构时,能保护用户上行信号正交性,避免符号间干扰,且传输速率损失约为9%,远低于传统拓展帧结构方法带来的损失,验证了方法的优越性。
