Narissra M. Punyanunt-Carter  Marilda J. Oviedo  Samer Melhem 《Qualitative Research Reports in Communication》2019,20(1):67-74

Based on questionnaire responses from 381 undergraduate students, this study sought to examine perceptions of Hispanics on television. Results revealed that college students perceive Hispanics portrayals on television are mainly stereotypical and often highlight negative perceptions (e.g., lazy and ill-tempered). Students regarded Hispanics to be hardworking and to prioritize culture. Perceptions of Hispanic men were mainly controlling figures and Hispanic women were mostly caretaking characters. These findings suggest that television can affect the way college students view and possibly communicate with Hispanics.  相似文献   

Triggering effects of mobile video marketing in nature tourism: Media richness perspective     

Ari Alamäki  Juho Pesonen  Amir Dirin 《Information processing & management》2019,56(3):756-770

The aim of this study was to investigate videos as potential triggers of behavior. Therefore, we applied the theories of triggers and media richness to learn about the triggering efficiency of mobile marketing videos on participants’ behavioral intentions. The experiment involved three distinct test groups, each comprising 41 student participants. From the perspective of media richness theory, we observed that the different kinds of videos had quite similar effects in terms of triggering behavioral changes. However, the mechanisms explaining why triggers were present differed for each video. Further, the results reveal that the consumer's position in the information search process was the most significant reason for the triggering of any kind of effect. In addition, the instructionally designed videos were able to exert an affective triggering effect: the more participants liked the video, the more it affected their participation intention and recall scores. This study extends the media richness research by demonstrating that the effects of media richness can vary within technically similar videos, as they form different logical connections among non-verbal visual cues related to a video's storyline.  相似文献   

When digitalized customers meet digitalized services: A digitalized social cognitive perspective of omnichannel service usage     

《International Journal of Information Management》2020

With the prevalence of digital technologies, various services have grown digitalized. Specific to the marketing section, multichannel has been gradually replaced by omnichannel, which aims to integrate all the physical and digital channels tightly. Although omnichannel has received considerable attention, there is still a dearth of research that theorizes the multi-faceted impacts of digitalization on omnichannel. This study thus extends social cognitive theory (SCT) to the digitalized context and contextualizes the digitalized customer and digitalized environment as mobile identity and channel integration quality, respectively. Moreover, based on the self-regulation process of human agency, we incorporate omnichannel self-efficacy, satisfaction, and habit as the agentic factors to interpret a customer’s conscious (ability and expectancy beliefs) and unconscious (automatic behavioral tendency) decision-making under the omnichannel setting. Through an online survey of 401 omnichannel customers, we find support for all the proposed hypotheses. Implications and limitations of this study are further discussed.  相似文献

Learning design and learning analytics in mobile and ubiquitous learning: A systematic review

Mobile and Ubiquitous Learning (m/u-learning) are finding an increasing adoption in education. They are often distinguished by hybrid learning environments that encompass elements of formal and informal learning, in activities that happen in distributed settings (indoors and outdoors), across physical and virtual spaces. Despite their purported benefits, these environments imply additional complexity in the design, monitoring and evaluation of learning activities. The research literature on learning design (LD) and learning analytics (LA) has started to deal with these issues. This paper presents a systematic literature review of LD and LA, in m/u-learning. Apart from providing an overview of the current research in the field, this review elicits elements of common ground between both communities, as shown by the similar learning contexts and complementary research contributions, and based on the research gaps, proposes to: address m/u-learning beyond higher education settings, reinforce the connection between physical and virtual learning spaces, and more systematically align LD and LA processes.  相似文献
