The collective storytelling organisational framework for social media use

The organisational implementation and use of social media for online community engagement is plagued with many challenges. The result is managers being frustrated at not achieving their desired results. Despite an increase in social media research, it is evident that some critical aspects of social media use by organisations are left unexplained by existing theories. The purpose of this research study is to investigate how social media is used within organisations to engage with its online community. The grounded theory method (GTM) was used to develop a substantive theory that increases understanding of this phenomenon. Two organisations were selected as the case studies. Both are industry leaders in South Africa, with one being a prominent retailer with a visible social media presence and the other, being a leading university in South Africa, which is actively growing its social media presence. The results show that organisations enter a collective storytelling process with their online community. The need to reduce risk to reputation and improve on the levels of online community engagement are identified as reasons for this. The strategic alignment of the social media function and the organisational social media use characteristics set the backdrop for the collective storytelling process, while content quality influences the richness of this process. Challenges associated with the collective storytelling process lead to the development and refinement of the organisational social media strategy, which in turn helps to reduce risk to reputation and improve online community engagement.

Telecommunications media for transport telematics

This article considers past and present European research into communications characteristics for transport telematics applications. The background for the work is derived from the European Commission's DRIVE/Transport Telematics programs and research projects, and CEN TC278 activities. The prospect that a single media cannot meet all the current applications requirements is supported by consideration of key services that have different communications requirements. However, media selection minimization and a migration path for homogeneous implementation of current research solutions are expostulated. The article concludes by questioning a defaulting media selection against our social consciences for matching media to requirements. The article is aimed at a readership with some technical knowledge and should be of interest to transport authorities and manufacturers intending to tackle the problems of implementing transport telematics systems

An idea for electromagnetic "feedforward-feedbackward" media

An idea for a new class of complex media that we name feedforward-feedbackward (FFFB) media is presented and some of the results of our theoretical work in analyzing plane wave propagation in the axial direction through these media are described. The concept of FFFB media, as introduced here, was inspired by the theoretical research of Saadoun and Engheta (1992, 1994) on a variation of artificial chiral media. Like chiral media, to our knowledge there are no naturally occurring FFFB media for the microwave frequency band; for this reason we introduce an idea for artificial FFFB media. The focus of this paper is on one conceptualization of such media, namely dipole-dipole FFFB media. First, we present the calculation of the necessary constitutive parameters for studying axial plane wave propagation. Then we solve the macroscopic Maxwell equations in the k domain for axial plane wave propagation in an unbounded source-free crossed-dipole FFFB medium. Finally, we present the dispersion equation for this medium in this case, discuss some of the physical properties of its roots and certain features of the polarization eigenstates, and speculate some of the potential applications of this medium.     

Social media discontinuation: A systematic literature review on drivers and inhibitors

Recent practical reports reveal that users leave social media. This behavior is named social media discontinuation (SMD) and is attributed to stress, fatigue, and further negative effects caused while using social media. While current literature points to some causes of SMD, a systematic literature review is needed to identify current research trends, carve out future research directions, and guide practitioners in encouraging users not to close their social media accounts. We thus examine existing research on SMD and identify its drivers and inhibitors. We conducted a systematic literature review by screening 1,270 studies, published in journals and conference proceedings since 2005. We focused on 32 studies that matched our screening guidelines. Our results come up with three SMD drivers and inhibitors categories: individual, relational and platform-specific. Individual drivers and inhibitors can further be divided into cognitive, behavioral, and emotional drivers, whereas platform-specific drivers are related to content and other social media characteristics. Most drivers are from the individual or the relational category. The findings contribute to SMD research by providing a comprehensive state-of-the-art perspective on what drives and inhibits SMD. This lets us develop valuable future research directions, such as the need for future research on SMD inhibitors, which have received little attention. The study further offers valuable practical implications to social media service providers.     

More Than Stories With Buttons: Narrative,Mechanics, and Context as Determinants of Player Experience in Digital Games

Recent research has attempted to describe meaningful experiences with entertainment media that go beyond hedonic enjoyment. Most of this research focuses on noninteractive media, such as film and television. When applied to digital games, however, such research needs to account for not only the content of the medium, but also the unique dimensions of digital games that distinguish them from noninteractive media. Experiences with digital games are shaped by the game mechanics that define the users' interaction with game content, as well as by the opportunities for social interaction that many games offer. We argue that the complex interplay of these dimensions (narrative, mechanics, and context) facilitates or inhibits meaningful user experiences in ways that are unique to digital games.

Social Media Addiction and Empathy: Moderating impact of personality traits among high school students

Potential addiction to social media is one of the problems that some people, especially adolescents, are facing. For this reason, many studies have been conducted in this field in recent years. There is no research investigating how empathy is associated with excessive and problematic online social media use, whilst some studies have associated social media use with empathy as the main component of social development. Hence, the purpose of this study is to examine the influences of Empathic Concern (EC) and Perspective Taking (PT) on social media addiction (SMA). Moreover, prior studies revealed that Internet addiction behavior of individuals varies according to differences in personality traits. Accordingly, we further intend to understand how the impacts of EC and PT on SMA are intensified by considering individuals’ traits differences, and thus, personality traits were included in the research model as the moderators. To assess the research model, the data collected through the distributed printed questionnaire among 592 high-school 15–18 years old students (42.1% male) were analyzed utilizing the partial least squares structural equation modeling (PLS-SEM) approach. The results revealed that both EC and PT significantly and negatively predict SMA. Furthermore, the moderating analysis showed that Extraversion negatively moderated the relationships between EC and SMA and PT and SMA. Further analysis revealed that while there were no differences across genders, behaviors associated with SMA were more common among students of high-income schools in contrast to low-income schools. Implications of the study are further discussed.
