In recent years, the emergence of social media influencers attracts the study of a realistic influence maximization (IM) technique. The theoretical performance of IM has become matured. However, it is not enough since IM has to be implemented in a social media environment. Realistic IM algorithms and diffusion models have been proposed, such as the addition of user factors or a learning agent. However, most studies still relied on the influence spread benchmark, which makes the usefulness questionable. This research is among the first IM study using Instagram data. In this study, two diffusion models are proposed, which are based on the original IC and LT models, with the addition of the engagement grade (EG) factor. An algorithm called IMFS (IM with followers score) is proposed to accommodate the new models as well as IC and LT. In addition, realistic benchmark methods are proposed, namely the average engagement of the activated users, and the overlapping between post likers and activated users. The result shows that the proposed models are 2-3x more realistic if compared to IC and LT.

This paper aims at contributing to financial reporting literature by proposing a conceptual interpretative model to analyse the corporate use of social media for financial communication purposes. In this perspective, the FIRE model provides a framework to study social media shifting the focus on the distinctive features that might enhance web investor relations. The model highlights these features through four building blocks: (i) firm identity (F); (ii) information posting (I); (iii) reputation (R); and (iv) exchange and diffusion (E). They represent key aspects to explore corporate communication activities and might offer a framework to interpret to what degree corporate web financial reporting exploits the potential of social media. Accordingly, the paper proposes metrics based on this model aimed at capturing the interactivity of corporate communications via social media, with a particular focus on web financial reporting. It tries to show the potential of this model by illustrating an exploratory empirical analysis investigating to what extent companies use social media for financial reporting purposes and whether firms are taking advantage of Twitter distinctive features of interaction and diffusion.

Abstract Social media is a virtual community or network platform that the public uses to achieve self-creation and it’s sharing with others; under the social media environment, self-media channels become more abundant, and the autonomy and originality of content dissemination are also continuously enhanced. When tourism enterprises face increasing market competition, personalized and targeted promotional programs will, to a certain extent, have a certain appeal to competitors’ potential customer groups, thereby providing tourism enterprise customers with relevant benefits for oriental information, and also serving as an important way for companies to develop new customers. Based on the summary and analysis of previous literature works, this paper expounded the research status and significance of social media environment, elaborated the development background, current status and future challenges of customer-oriented information analysis for tourism enterprises, introduced the methods and principles of customer’s transfer value and life cycle and social media environment’s cognitive composition, proposed a sentiment model of tourist-oriented information analysis under the social media environment, and analysed the management strategy and scheduling platform of customer-oriented information, constructed an analysis system of customer-oriented information in social media environment, performed the reliability, validity, transfer and perception value analysis of customer-oriented information and finally conducted case simulation and its result analysis. The study results of this paper provide a reference for further researches on the customer-oriented information analysis for tourism enterprises under the social media environment.

This article investigates how platformisation changes the practices of content production and distribution through the case of the web series, Druck (tr. Pressure (2018–), for the public service content network ‘funk’ (ARD and ZDF). An analysis of the German adaptation of the Norwegian television and web series Skam (tr. Shame) (NRK3, 2015–2017) shows how public service broadcasting (PSB) in Germany is changing due to the influence of social media. To reach a younger audience, PSB has to meet them on third-party platforms. Consequently, PSB must provide content that fits the mobile media environment of social media.

Purpose Existing studies reflect that traditional teaching–learning relationships between supervisors and graduate students have become disjointed with actuality seriously. In particular, there are practical difficulties in handling many students from coursework-based postgraduate degrees under current university curricula. Therefore, this study aims to explore the relationship between research supervisors and graduate students on social media, which is popular among students. Design/methodology/approach This study surveyed 109 graduate students from two majors (population around 100 each) of a university in Hong Kong to explore their information usage for research on social media, related attitudes and their perceived supervisor relationships. The differences between the two majors were also compared. Findings The authors’ findings indicated that graduate students were active on social media, and social media has successfully provided effective alternate ways for students to communicate with their research supervisors. Social media could improve relationships between supervisors and research students and among fellow students. Besides education purposes, students also discussed their personal affairs on social media with supervisors, demonstrating enhanced trusted relationships. Graduate students also showed confidence in the further application of social media in higher education. Some differences between respondents from the two programs were also found in terms of communication contents, strengths, personal preferences and purposes for using social media. Originality/value Scant studies focus on the relationship between supervisors and graduate students under the current social media environment, especially for students from coursework-based postgraduate degrees. At a deeper level, for the widespread use of social media in the information age, this study explores the specific changes brought about by social media. Therefore, this study is of great theoretical and practical value to graduate education under the current social media environment.

The problem of identifying a seed set composed of K nodes that increase influence spread over a social network is known as influence maximization (IM). Past works showed this problem to be NP-hard and an optimal solution to this problem using greedy algorithms achieved only 63% of spread. However, this approach is expensive and suffered from performance issues like high computational cost. Furthermore, in a network with communities, IM spread is not always certain. In this paper, heterogeneous influence maximization through community detection (HIMCD) algorithm is proposed. This approach addresses initial seed nodes selection in communities using various centrality measures, and these seed nodes act as sources for influence spread. A parallel influence maximization is applied with the aid of seed node set contained in each group. In this approach, graph is partitioned and IM computations are done in a distributed manner. Extensive experiments with two real-world datasets reveals that HCDIM achieves substantial performance improvement over state-of-the-art techniques.

With the advent of popular social media platforms, news journalism has been forced to re-evaluate its relation to its audience. This applies also for public service media that increasingly have to prove its utility through audience ratings. This ethnographic study explores a particular project, the development of ‘concept bible’ for the Finnish Broadcasting Company YLE’s online news; it is an attempt to solve these challenges through new journalistic practices. The study introduces the concept of ‘nuanced universality’, which means that audience groups’ different kinds of needs are taken into account on news production in order to strengthen all people’s ability to be part of society. On a more general level, the article claims that despite its commercial origins, audience segmentation can be transformed into a method that helps revise public service media principles into practices suitable for the digital media environment.

Abstract Building a brand is a long-term process and it also applies to the world of social media. It is said that building a good brand reputation takes years, but it can be ruin in a moment. Therefore, it is important to look responsibly at all the aspects that have a role in building a brand on social media. The actual experience with the brand on social media is able to significantly affect brand building. The study focuses on exploring brand-building relationships in the social media environment. We selected a set of factors to predict customer experience with the brand in a social media environment and then we examined the relationship between this customer experience and the perceived brand image. 476 respondents filled out the electronic questionnaire. The study puts the greatest emphasis on respondents aged 20 to 35 years. We used correlation analysis to investigate the relationships in this issue. Out of the seven investigated relationships, up to two cases with medium dependence were confirmed by the strong relevance of relationships. The results support the importance of using social media tools for branding purposes, because these tools are the ones with the greatest ability to influence the people’s perception and attitude. It is also the fastest and one of the most personal ways to communicate with the customer. It happens in real time and it can convey the real emotion if performed right which all together help to trigger the user action. The findings of this study can guide marketing activities for companies to make the return on investment in social media as high as possible. The research offers a new perspective on selected factors and their role in creating social media experience and subsequently a brand image.
