This study seeks to develop a general framework for evaluating communication platforms in e‐commerce, and then apply the framework to investigate what factors have impeded m‐commerce from taking off in the specific context of China.

The paper proposes a three‐dimension framework for evaluating a communication platform in e‐commerce, which features reach, richness, and costs of communications as its salient characteristics. Grounded on the framework, a comparative analysis is conducted using data from a survey sponsored by the Ministry of Commerce of China. The analysis, from the user's perspective, compares facilitators and inhibitors for using communication platforms in two different contexts, the mobile communication platform in m‐commerce vs the fixed communication platform in the “classical” e‐commerce.

The study finds that, compared with e‐commerce over the fixed communication platform, the m‐commerce in China enjoys relatively great communication reach but suffers from relatively low communication richness. In the mean time, costs of communications do not seem to be a major barrier for m‐commerce growth.

The three‐dimension framework can serve as an underlying model not only to evaluate currently available communication platforms for e‐commerce, but also to address economic calculus of benefits and costs of emerging communication platforms.

With the prevailing use of online communication platforms, this study revisits the definitions of trust in an online context. By exploring organizational online communications from a practitioners' perspective, a conceptual framework that illustrates the nature of trust and its relationship with dialogic communication between organizations and organizations' stakeholders in the digital era is proposed.

A total of 27 in-depth interviews were conducted with public relations and marketing practitioners involved in coordinating organizational online communications in Hong Kong.

From the practitioners' perspective, stakeholders' online trust toward an organization, which is a hybridity of initial and rapidly evolving trust, begins with stakeholders swift and initial judgment of the organization according to category-based cues (including knowledge-based attributes of the organization, institutional cues, and particular attributes of online dialogic communication) available on online platforms and further develops over time. Practitioners regard the integration of online and offline communication platforms to be the most effective way to build trust in organization–stakeholder relationships in the digital era, while dialectical tensions can hinder trust formed in online communication.

Along with the proposed conceptual framework, this study advances the discussion of online trust in public relations practices from the practitioners' perspective. A qualitative approach provides rich descriptions that may help to enrich theories in public relations and communication management regarding the interplay of trust and dialogic communication in organizational practices in the digital era.

India has the biggest number of active users on social media platforms, particularly Twitter. The purpose of this paper is to examine public sentiment on COVID-19 vaccines and COVID Appropriate Behaviour (CAB) by text mining (topic modeling) and network analysis supported by thematic modeling.

A sample dataset of 115,000 tweets from the Twitter platform was used to examine the perception of the COVID-19 vaccination and CAB from January 2021 to August 2021. The research applied a machine-learning algorithm and network analysis to extract hidden and latent patterns in unstructured data to identify the most prevalent themes. The COVID-19 Vaccine Hesitancy Amplification Model was formulated, which included five key topics based on sample big data from social media.

The identified themes are Social Media Adaptivity, Lack of Knowledge Providing Mechanism, Perception of Vaccine Safety Measures, Health Care Infrastructure Capabilities and Fear of Coronavirus (Coronaphobia). The study implication assists communication strategists and stakeholders design effective communication strategies using digital platforms. The study reveals CAB themes as with Mask Wearing Issues and Employment Issues as relevant themes discussed on digital channels.

The themes extracted in the present study provide a roadmap for policy-makers and communication experts to utilize social media platforms for communicating and understanding the perception of preventive measures of vaccination and CAB. As evidenced by the increased engagement on social media platforms during the COVID-19-induced lockdown, digital platforms are indeed valuable from the communication perspective to be proactive in the event of a similar situation. Moreover, significant themes, including social media adaptivity, absence of knowledge-providing mechanism and perception of safety measures of the vaccine, are the critical parameters leading to an amplified effect on vaccine hesitancy.

The COVID-19 Vaccine Hesitancy Amplification Themes (CVHAT) equips stakeholders and government strategists with a preconfigured paradigm to tackle dedicated communication campaigns and assess digital community behavior during health emergencies COVID-19.

The increased acceptance of vaccines and the following of CAB decrease the advocacy of mutation of the virus and promote the healthy being of the people. As CAB has been mentioned as a preventive strategy against the COVID-19 pandemic, the research preposition promotes communication intervention which helps to mitigate future such pandemics. As developing, economies require effective communication strategies for vaccine acceptance and CAB, this study contributes to filling the gap using a digital environment.

Chan et al. (2020) recommended using social media platforms for public knowledge dissemination. The study observed that the value of a communication strategy is increased when communication happens using highly trusted and accessible channels such as Twitter and Facebook. With the preceding context, the present study is a novel approach to contribute toward digital communication strategies related to vaccination and CAB.

Social media communications on platforms such as Facebook and LinkedIn can allow managers to interact cost effectively with trading partners. However, although most firms have an online presence on multiple social media platforms, the question remains as to whether marketers’ widespread social media investments are beneficial for firms. The paper aims to discuss this issue.

This paper presents competing hypotheses to explore how firms’ investment in one form of social media impacts activity on another form of social media. To do so, the authors draw on a data set of 208 large Australian organizations using objective social media activity metrics that measure business-to-business (B2B) audience engagement.

The findings suggest that widespread social media activity on LinkedIn, Twitter, and YouTube negatively affects a firm’s marketing activity on Facebook. The results indicate that having a social media preference whereby firms focus on a specific social media platform is more effective in forming successful inter-organizational relationships than a multiplatform approach.

The study contributes to the sparse research that seeks to leverage social media for audience engagement beyond a business-to-consumer context. The study’s findings provide insights into the key mechanisms that underlie firms’ B2B social media strategies, and in so doing, offer a fresh perspective on the importance of interactive marketing communication.

The study explores the role of dialogic public communication and information quality (IQ) in evaluating the operational performance of donation-based crowdfunding (DBC) tasks. These tasks are primarily used to support disaster relief operations. The authors also test the influence of cognitive trust and swift trust as moderating variables in explaining the relationship between both IQ and dialogic communication with operational performance.

The authors used a primary survey to test the hypotheses. A total of 203 responses were collected from multiple crowdfunding platforms. The authors used archival data from task creators on donation-based crowdfunding platforms, and a structured questionnaire is also used to collect responses. Data are analyzed using Warp PLS 6.0. Warp PLS 6.0 works on the principle of partial least square (PLS) structured equation modeling (SEM) and has been used widely to test path analytical models.

The authors found out that the operational performance is explained significantly by the quality of information and its association with dialogic public communication. The results support the arguments offered by dialogic public communication theory and trust transfer theory in assessing the operational success of DBC. The study also confirms that cognitive trust positively moderates the relationship between IQ and organizational public dialogic communication and operational performance. It is also revealed that the duration of the DBC task has no significant control over dialogic public communication.

The study lays practical foundations for task creators on DBC platforms and website designers as it sets the importance of both IQ and dialogic communication channels. The communication made by the task creator and/or the DBC platforms with the donors and potential donors in the form of timely and appropriate information forms the key to the success of any DBC task. The study also helps task creators choose a suitable platform to improve performance.

The authors propose a unique framework by integrating two theoretical perspectives: dialogic public relation theory and trust transfer theory in understanding the operational performance of donation-based crowdfunding tasks. The authors address DBC tasks catering to disaster relief operations by collecting responses from task creators on DBC platforms. The study uniquely positions itself in the area of information and communication.

In the Web 2.0 era, users massively communicate through social networking services (SNS), often under false expectations that their communications and personal data are private. This paper aims to analyze privacy requirements of personal communications over a public medium.

This paper systematically analyzes SNS services as communication models and considers privacy as an attribute of users’ communication. A privacy threat analysis for each communication model is performed, based on misuse scenarios, to elicit privacy requirements per communication type.

This paper identifies all communication attributes and privacy threats and provides a comprehensive list of privacy requirements concerning all stakeholders: platform providers, users and third parties.

Elicitation of privacy requirements focuses on the protection of both the communication’s message and metadata and takes into account the public–private character of the medium (SNS platform). The paper proposes a model of SNS functionality as communication patterns, along with a method to analyze privacy threats. Moreover, a comprehensive set of privacy requirements for SNS designers, third parties and users involved in SNS is identified, including voluntary sharing of personal data, the role of the SNS platforms and the various types of communications instantiating in SNS.

This study aims to examine how sport fans' intention to donate to college athletics differs by the type of communication and by the interactivity of communication when a college athletic department uses a social cause for marketing.

To discover differences in donation intention, the study adopts a two (social media/newspaper) by two (interactive/non-interactive) factorial experiment in which the study's created scenario is randomly presented to subjects. Participating in the online survey are 184 collegiate sport fans at a university in the American Midwest. Collected data are analyzed on the analysis of variance.

Results show that fans demonstrating the highest donation intention are those in the group of fan-interactive marketing on social media. Those showing the lowest are in the group of non-interactive marketing on newspaper. Between marketing interactivity and marketing platform, no interaction effect is found.

The study tests the effectiveness of marketing communication in the context of collegiate sports and identifies the impact of social media on college sport fans' donation intention. For collegiate athletic administrators designing a cause-related marketing campaign, this study provides practical information on how to use social media in delivering fan-oriented activities.

Gig workers form the backbone of any crowdsourcing platform where they showcase their talent and choose a job of their choice and freedom. The study explores the role of information quality (IQ) and social-mediated dialogue (SMD) in evaluating gig worker engagement and productivity on crowdsourcing platforms. The authors also propose to understand how gig worker productivity could be improved under the moderating effect of game elements.

A conceptual model was developed and empirically tested by integrating media richness theory and dialogic public relation theory. Data were collected from gig workers that are involved in crowdsourcing activities for the past three years. An overall sample of 346 gig workers contributing to at least one of the crowdsourcing platforms was collected. The authors tested the hypotheses using Warp PLS 7.0. Warp PLS 7.0 uses partial least square (PLS) structured equation modeling (SEM) and has been used widely to test path analytical models.

Results reveal that the information quality plays an essential role in the SMD, thereby fostering gig workers' productivity and engagement, which could be improved in the presence of game elements due to their nature of supporting rewards. However, engagement in the platform leading to improved productivity was not supported.

The study lays practical foundations for crowdsourcing platforms as it sets the importance of both IQ and dialogic communication channels. The two-way communication between gig workers and the platforms via accurate, timely, valuable and reliable information forms the key to the task's success. The introduction of the right game element will help to achieve better engagement and productivity.

This study also offers a new dimension to media richness theory and dialogic public relation theory in crowdsourcing platforms. The results would help platform designers and gig employers understand gig workers' quality and performance in a platform economy. The study uniquely positions itself in the area of crowdsourcing platforms by using game elements.

This study aims to examine how three perceived interactivity attributes of massive open online courses (MOOCs), namely, perceived active control, perceived synchronicity and perceived two-way communication, impact individuals' engagement and continuance intention of MOOCs through the stimulus-organism-response (S-O-R) lens and how that effect differs between male and female users.

Drawing upon S-O-R as an overarching theoretical framework, this study conducted an empirical study in China and collected 294 valid questionnaires from online learners. Structural equation modeling approach was used to examine the proposed research model.

Empirical results suggest that perceived active control, perceived synchronicity and perceived two-way communication are significant stimuli of individuals' continuance intention of MOOCs, and the influences of perceived active control and perceived synchronicity are partially or fully mediated by engagement on the platform. Multi-group analysis results further indicate that perceived synchronicity has a stronger influence on engagement on the platform for males, while perceived active control and perceived two-way communication are more salient in stimulating engagement on the platform for females.

Research findings from the present study can serve as the foundation to guide MOOCs’ administrators to respond to the needs of participants through interactivity designed into the platform and shed light on possible key solutions of high dropout rates in MOOCs.

This study uncovers the mediating mechanism of affective engagement between interactivity and continuance intention in the emerging context of the latest online learning platform MOOCs and reveals the behavioral differences between females and males regarding their affective reactions to the three interactivity attributes.

The purpose of this paper is to examine the potential applications of stratospheric communication platforms (SCP), which have been recently introduced as an alternative for satellite communications.

Various applications, solutions and services are planned by using aircraft or airship SCP, which could be classified as digital narrowband or broadband, depending on the broadband required. The platforms as base stations can provide service for fixed and mobile applications, with commercial and military solutions. Subscribers will use uplink to the platform for transmitting and receiving information, where onboard SCP switching devices will downlink to the ground station and route traffic directly to other subscribers within the same platform coverage, to another platform via optical inter‐platform links, trough heterogeneous networks including satellite or to the terrestrial telecommunications network. Each SCP can deploy an antenna for large coverage area or a multibeam antenna capable of projecting numerous spot beams within its potential coverage area.

This paper outlines the findings of fixed and mobile applications, features, testing and some specific development programs of SCP using aircraft solutions, such as SkyTower and airship solutions, such as CRL/TAO/NAL.

Particular consideration is given to the use of SCP for delivery of future broadband, broadcast and multimedia wireless communications including research for new communication, navigation and surveillance (CNS) implications.

SCP will provide communication facilities that can exploit the best features for both terrestrial and satellite schemes.

Emerging solutions of voice, data and video over IP are offered by SCPs operating in the stratosphere at altitudes of up to 25 km.
