The future of communication and advertising is mobile. There is, however, little empirical evidence as to exactly how mobile advertising works. This research examines the role of mental imagery elicited by mobile advertising and its mediating effect on trust in the advertising message (ad trust) and purchase intention. Using a 2 × 2 factorial experimental design, we examined the influence of the type of message – SMS vs. MMS – and type of content – informational vs. transformational – on the three dimensions of mental imagery: vividness, quantity and elaboration. Results show a greater impact of MMS mobile ads and transformational ads on vividness and elaboration, while SMS mobile ads have a greater impact on the quantity dimension. The study also suggests that ad trust can be improved by enhancing the mental imagery elicited by mobile ads. Vivid and elaborate mental imagery mediates the effect of the type of ad on ad trust and exerts a positive influence on purchase intention. These findings have important implications for mobile advertisers since overcoming trust issues remains a major obstacle in the adoption of this medium. In addition, practical aspects of mobile ads’ conception and design are discussed and directions for future research are suggested.  相似文献

新媒体联盟《2012年地平线报告》指出,平板计算是未来五年可能影响教育发展最重要的六项技术之一。平板电脑由于克服了传统PC在时间、地点等方面的客观限制,一经问世,即抢占电脑市场,成为颇具前景的电子产品。它颠覆了以往PC已经成熟的Web模式,其多媒体特性、移动性、便捷的操作性以及资源分发模式,可能会对目前在线学习模式进行迭代和补充,促进远程教育教学发展,因此受到国内外广泛关注。目前,平板电脑在远程教育中的应用已经涉及数字阅读、视频公开课、电子教材、电子书包等多方面,但由于普及率、资源开发成本、交互屏障、消费意愿等综合因素,其在远程教育中的广泛应用还没有形成整体的成熟方案和模式,还需要远程教育机构、教学设计者、软件开发者及决策部门实践创新破局,构建符合各类学员特点,更方便易用、大众化的全民教育、终身教育的远程教育模式。  相似文献

Data exchange is the problem of taking data structured under a source schema and creating an instance of a target schema, by following a mapping between the two schemas. There is a rich literature on problems related to data exchange, e.g., the design of a schema mapping language, the consistency of schema mappings, operations on mappings, and query answering over mappings. Data exchange is extensively studied on relational model, and is also recently discussed for XML data. This article investigates the construction of target instance for XML data exchange, which has received far less attention. We first present a rich language for the definition of schema mappings, which allow one to use various forms of document navigation and specify conditions on data values. Given a schema mapping, we then provide an algorithm to construct a canonical target instance. The schema mapping alone is not adequate for expressing target semantics, and hence, the canonical instance is in general not optimal. We recognize that target constraints play a crucial role in the generation of good solutions. In light of this, we employ a general XML constraint model to define target constraints. Structural constraints and keys are used to identify a certain entity, as rules for data merging. Moreover, we develop techniques to enforce non-key constraints on the canonical target instance, by providing a chase method to reason about data. Experimental results show that our algorithms scale well, and are effective in producing target instances of good quality.  相似文献

ABSTRACT

The purposes of this study were to examine (a) similarities and differences in constraints to and constraint negotiation for masters games (MG) participation, and (b) the relationships among constraints, constraint negotiation, and intention to participate in the World Masters Games 2021 Kansai, across international sport tourists, domestic sport tourists, and sport excursionists. An online survey was conducted with 449 Japanese people who participated in MGs within the last three years. Our results indicated that international sport tourists experienced higher levels of psychological, physiological, interpersonal, financial, tourism, commitment, MG-specific constraints than domestic sport tourists and sport excursionists, although physiological constraints did not differ between international and domestic sport tourists. Conversely, international and domestic sport tourists utilized tourism and MG-self-adaptation negotiation strategies more than sport excursionists. Lastly, constraints to and constraint negotiation for the past MG were not related to the intention of participation in the World Masters Games 2021 Kansai across the three groups. These results suggest that this typology of sport tourists – international, domestic, and excursionist – is an effective framework to understand constraints and negotiation as well as other behaviors and experiences of Japanese sport tourists.  相似文献

Due to the proliferation of Web 2.0 technology, e-commerce has evolved into social commerce. In this social commerce era, consumers are increasingly dependent on each other and look for social support (informational and emotional) online even before making purchases. This study examines the content of consumer reviews, a fundamental construct of social commerce. Topics expressed in consumer reviews (collected from Amazon.com) are explored using a machine learning technique (i.e. latent semantic analysis). This study documents the thematic differences between positive and negative reviews and finds that negative reviews report service-related failures while positive reviews relate more to the product, among other things. Next, the informational support aspect of social commerce is explored by identifying the topics expressed in reviews that are helpful in purchase decisions. The findings demonstrate that potential customers (i.e. those who would like to purchase a product in the near future and currently are reading reviews with the intention to decide whether or not to buy that product) find the negative reviews containing service failure information and the positive reviews containing information on core functionalities, technical aspects, and aesthetics to be more helpful. Theoretical and managerial implications are discussed.  相似文献
