Multimedia augmented m-learning: Issues,trends and open challenges

The advancement in mobile technology and the introduction of cloud computing systems enable the use of educational materials on mobile devices for a location- and time-agnostic learning process. These educational materials are delivered in the form of data and compute-intensive multimedia-enabled learning objects. Given these constraints, the desired objective of mobile learning (m-learning) may not be achieved. Accordingly, a number of m-learning systems are being developed by the industry and academia to transform society into a pervasive educational institute. However, no guideline on the technical issues concerning the m-learning environment is available. In this study, we present a taxonomy of such technical issues that can impede the life cycle of multimedia-enabled m-learning applications. The taxonomy is devised based on the issues related to mobile device heterogeneity, network performance, content heterogeneity, content delivery, and user expectation. These issues are discussed, along with their causes and measures, to achieve solutions. Furthermore, we identify several trending areas through which the adaptability and acceptability of multimedia-enabled m-learning platforms can be increased. Finally, we discuss open challenges, such as low complexity encoding, data dependency, measurement and modeling, interoperability, and security as future research directions.

Predicting smartphone brand loyalty: Consumer value and consumer-brand identification perspectives

With the growth and competition of the smartphone industry, developing a better understanding of what drives consumers' loyalty to smartphone brands has become an important issue for academics and practitioners. This study hypothesizes four determinants of smartphone brand loyalty based on the perspectives of consumer value and consumer-brand identification. Furthermore, this study also explores the moderating effects of age and gender differences on the determination process of smartphone brand loyalty. Data collected from 157 respondents was tested against the research model using a partial least squares (PLS) approach. The results indicate that functional value, emotional value, social value, and brand identification have a positive influence on smartphone brand loyalty. Of the two moderators, results show that age enhances the emotional value-brand loyalty and social value-brand loyalty linkages but weakens the brand identification-brand loyalty relationship. However, gender does not play a moderating role in the determination of smartphone brand loyalty. The results of this study provide several important theoretical and practical implications for smartphone brand management.     

How system quality influences mobile BI use: The mediating role of engagement

Despite the recognized value that mobile BI (m-BI) brings to firms, our understanding of the use of m-BI and its determinants are limited. In this study, we suggest that m-BI system quality characteristics may be among the factors that influence m-BI use. Yet, in the information systems (IS) literature there is mixed support for the relationship between system quality and system use at the individual level. Given there is research suggesting that engaged users are an indication of the technology’s success, we believe that ‘engagement’ may be the key to understanding the relationship discrepancy between system quality and use. To address this gap, we conducted a quantitative study of key informants who use m-BI, to understand what the key m-BI capabilities are and other success dimensions perceived as important by users. The results indicate that m-BI system quality attributes affect m-BI use indirectly through engagement, with this finding contributing to understanding of the complexity of IS use in mobile technologies.     

手机颜色词的类型特征及语用功能

"极夜蓝"、"成功银、骑士灰"、神秘紫、"迷幻红"、等这些新出现的手机颜色词是一类值得研究但却没有引起足够关注的新词.从"四个世界"理论出发,有从物理世界、文化世界、心理世界产生的手机颜色词,它们都具有一些特殊的语用功能.     

英汉对比下的大学英语翻译教学探索

翻译是一种技术层面的实践,是一种语言层面的转换,更是一种跨文化交际现象。英汉对比是翻译的前提,也是搞好翻译教学不可缺少的理论基础,可以说,自觉或不自觉地进行英汉对比,特别是跨文化比较整个贯穿于英汉翻译的教学过程中,而有意识地把英汉对比,特别是文化意识寓于翻译教学之中,则是当前搞好翻译教学的有效途径,特别是在大学英语教学改革中起着极其重要的作用。     

危机传播中地方媒体的角色、功能与策略

地方媒体作为社会的"守望者"、"监督者"以及沟通政府与公众的重要桥梁,其对与公共利益紧密相关的重大决策信息传播的缺席常常是导致危机发生的重要原因之一。因此,从危机传播视角出发,负责任的地方媒体在危机传播中应以价值定位取代功能性定位,明确自身作为社会监测者的基本角色,履行好危机传播中揭示危机真相和进行公民教育的传播功能。在传媒所受体制性束缚一时难以改变的情况下,地方媒体危机传播功能的实现要靠"打时间差"、"边缘突破"、"协同作战"等策略性实践手段来实现。
