Although there are a number of studies on the factors affecting the continuance usage intention for social network services (SNS), the studies on the integrated model encompassing SNS qualities (information, system, and service quality, and hedonic value, which are gratifications for SNS usage), flow, relationship quality (which are trust and satisfaction), and continuance intention are almost non-existent. Based on Bagozzi’s self-regulation framework, the IS success model, uses and gratification theory, and flow theory, the purpose of this paper is to examine the qualities and hedonic value of SNS, which have an influence on flow experience and relationship quality which are posited to affect the continuance usage intention.

This study used an e-mail survey method to collect 460 questionnaires for the final sample. The sample of the study includes college students or job workers who have experience in using SNS. Various user categories in terms of gender, school degree, occupation, usage years, and daily time of usage were included.

The study results show that system, service quality, and hedonic value have an impact on flow experience, information and service quality, and hedonic value influence the relationship quality of SNS. The flow experience and relationship quality while using SNS affect the continuance usage intention of SNS. This results show that the consideration of various SNS qualities, hedonic value, flow experience, and relationship quality is necessary to actively explore the factors for continuance usage intention for SNS.

IS managers trying to understand reuse intent can use surveys on information, system, and service quality, and hedonic value. Practitioners should constantly incorporate and develop various activities or useful applications to allow people to reach out to each other, to reinforce users’ attention, interaction, and increase social connections, trust, satisfaction, and further intensify users’ intention to use, increasing SNS value. The findings explain a mechanism through which SNS users’ continuance intention is built. Understanding this mechanism provides valuable information for practitioners to understand the qualities driving SNS users’ intention to revisit SNS.

This study sheds light on the existing literature on website usage that focuses on the design qualities as this paper has combined website quality perspective, i.e., information, system, and service quality, and hedonic value, and the flow and relationship perspective to investigate how these constructs would affect users’ intention to continuously use SNS. On the basis of four theories, Bagozzi’s self-regulation framework, IS success model, users and gratification theory, and flow theory, this study extended the previous studies on SNS by adding information, system, and service quality, hedonic value, flow and relationship quality as second-order constructs affecting continuance intention.

Previous studies have produced mixed findings regarding the relationship between social networking site (SNS) use and psychological outcomes. To provide new evidence on this relationship, this study investigates the influence of SNS involvement on psychological outcomes. This study also examines the moderating role of information sharing on the link between SNS involvement and relationship quality and that between SNS involvement and social life satisfaction.

This study investigates a sample of 383 Facebook users in Vietnam. Structural equation modeling is performed to test the theoretical model and research hypotheses.

Results show that SNS involvement positively influences information sharing, relationship quality and social life satisfaction. In addition, information sharing positively affects relationship quality, which in turn is positively related to social life satisfaction. Moreover, information sharing positively moderates the link between SNS involvement and relationship quality but negatively moderates that between SNS involvement and social life satisfaction.

This study sheds a new light on the effect of SNS involvement on psychological outcomes. Specifically, the findings of this study help clarify the influence of SNS involvement on social life satisfaction. Furthermore, this study provides evidence on the moderating mechanism of information sharing on the link between SNS involvement and psychological outcomes. The findings can help SNS users and administrators make better decisions in their SNS engagement.

Users' continuance intention is vital to the future of mobile social networking service (SNS) with rapid development and intensive competitions among its providers. The purpose of this research is to identify the factors affecting mobile SNS users' continuance intention.

Data from an online survey administered to 228 mobile SNS users are used to test the research model through the use of structural equation modelling.

The results show that flow, perceived usefulness and satisfaction determine continuance intention of mobile SNS. Moreover, the authors found that referent network size and perceived complementarity are the main factors affecting flow, whereas information quality is the main factor affecting perceived usefulness. Only system quality significantly affects satisfaction.

The results imply that mobile service providers need to take the functional characteristics of the mobile SNS (e.g. system quality and information quality), network externalities (referent network size and perceived complementarity) and flow experience into consideration when encouraging users' continuance intention towards mobile SNS.

Extant research has focused on initial adoption and usage of mobile SNS and has seldom considered post-adoption usage, which is critical to mobile service providers' success. This research tries to fill the gap by examining continuance intention to use mobile SNS. The theory embedded within the IS success model, network externalities and flow theory articulated that these three research domains can be integrated to better understand the factors that influence mobile SNS users' continuance intention.

Emerging social networking sites (SNSs) are less advantageous than leading SNSs in attracting users. They might stand a better chance if they know what users want. The purpose of this paper is to study factors that urge Facebook users to switch to Instagram to reveal how latecomers in the SNSs circuit can win the hearts of users.

This study proposes an SNS switching framework that is adapted from the demographic Push-Pull (PP) migration model to investigate users’ switching intention. Structural equation modeling was applied to analyze the data collected from 260 Instagrammers who all had experience using Facebook before moving on Instagram.

Results show that socializing and system quality of the SNS negatively affect users’ switching intention, while attractiveness of the alternative, peer influence and critical mass do the opposite. Surprisingly, enjoyment is not associated with switching intention.

SNSs switching may not mean a complete abandonment of previous SNSs. In many occasions, users simply become less active in one SNS and more active in other SNSs. The PP migration model provides a useful tool to understand the patterns as well as competing forces that influence the migration of SNS users, pushing them away or pulling them to new alternative sites. Specifically, pulling demonstrates to be a stronger influence than pushing.

This study suggests that SNS operators should satisfy users’ needs for socializing, maintain high system quality, provide peer influence tools and create their own attractive features, in order to retain existing customers or induce new users to switch.

This is one of the earlier empirical studies to investigate users’ switching intention from Facebook to Instagram with a valid sample. In addition, the present study approaches pull and push effects by multiple constructs, providing a clearer picture of what constitutes the pull and push forces.

The purpose of this study is to identify the factors leading to adoption of social networking sites (SNS) by librarians of entrepreneurial libraries to provide support to business community in their market research. Identification of these adoption factors will help to design SNS in the way that led to their seamless diffusion in university libraries, making them capable of providing reliable and useful market knowledge to the business community.

To meet the research objectives, this study is based on the technology adoption model (TAM). The survey was conducted with 50 librarians of various universities across Europe, Asia, America, Africa and Australia, sampled through non probabilistic sampling techniques-purposive and snowball sampling. The collected data are analyzed through partial least squares structural equation modeling (PLS-SEM) to estimate the formulated structural equation model using SmartPLS 3.2.9 software version.

The results indicate that university librarians have high perception about usefulness and ease of using SNS for meeting their business objectives. The perceived usefulness (PU) is solely based on the prolonged adoption of SNS technology in personal lives of the librarians. The perceived ease of use (PEU) is triggered by the increasing quality of evolving SNS technology, especially user friendliness. The prolonged use of technology, increasing market entry of brands and improving quality of SNS will overcome librarian resistance to use SNS for market research related support to business community. Evolving technologies are more likely to be adopted seamlessly in entrepreneurial libraries.

This study has implications for librarians, entrepreneurs and technology providers. Librarians should have flexible technology adoption policies in place to keep technology adoption synchronized with changing market conditions. Entrepreneurs should share clear and accurate business needs as well as practicing ethical and lawful business practices. They should also help libraries to gain new skills to make future adoption easier. Technology providers should focus on improving the quality of their technology by increasing their functional utilities, performance and reliability as well as making them more user-friendly.

This study investigates technology adoption of SNS in libraries from the perspective of providing market research related services to entrepreneurs rather than just digitalizing library services for student users.

This paper aims to explore the formal (i.e. contracts, standards, processes, and structure) and informal (i.e. social structure, norms, information sharing, and value system and culture) governance instruments used in supply networks and their influence on quality.

This research is qualitative-exploratory in nature, involving semi-structured interviews with 20 managers from three essential layers in the dairy industry's supply chain: companies that supply essential inputs to milk producers; milk producers; and milk cooperatives.

Analysis of the generated data show that formal governance instruments have a strong and/or weak influence on products' and operations' quality in the dairy industry context; informal instruments have a strong and/or weak influence on quality, as a counterpart to formal instruments; and the integration of verified governance instruments positively influences the quality of products and operations.

This paper offers several managerial and practical implications. The first is to encourage suppliers of primary inputs and milk producers to invest in the formal structure, primarily in formal contracts with each other. The second implication suggests the relevance of creating different training and qualification courses with members from all organizational levels. Third, there is a need for cooperatives, encompassing all industries, to consider several informal instruments, complementary to contracts and standards currently used for processes.

Governance instruments can lead to desired supply chain outcomes, including those related to quality. Although previous supply chain studies have investigated the relationship between governance instruments and the supply chain, and quality management and the supply chain, studies on governance instruments' influence on supply chain quality are limited.

Despite the importance of incorporating social media with customer relationship management (CRM), the implementation of social CRM is still in its initial stages for a majority of green brands. The purpose of this paper is to examine whether consumers’ perception-based factors of the online CRM tactics through social media (i.e. perceived marketer-dominated information quality, perceived interaction quality, and perceived service content quality in social media) offered by the green brand were related to the perceived customer retention orientation (CRO) of the green fashion retailer, which was related to patronage intention towards the green retailer, and the moderating effect of green consciousness on the link between perceived CRO of the green retailer and patronage intention.

Data were collected from social media users (n=631) using a consumer panel via an online survey. Structural equation modelling was employed to test the proposed model and research hypotheses.

This study found that the perceived CRO of the green retailer was positively related to patronage intention. The perceived marketer-dominated information quality and perceived service content quality in social media were positively related to the perceived CRO of the green retailer. Green consciousness moderated the link between perceived CRO and patronage intention.

First, this study contributes to the further theoretical understanding of the underlying factors that influence customer perception of the CRO of the green retailer and green patronage intention. Second, on a managerial level, this proposed model provides green retailers with beneficial insights into the development of successful social CRM.

This study aims to analyze the effect of religiosity (RE), halal knowledge (HK) and halal certification (HC), attitudes, subjective norms and vaccine quality on the Muslim community’s intention to use halal vaccines in Indonesia.

This study involved 725 Muslim respondents in 32 Indonesian provinces. The model used was based on the theory of reasoned action development with the partial least squares structural equation modeling as the data processing tool.

The study discovered that RE, HK and HC did not affect the intention of Muslims to use halal vaccines. In addition, the MUI (Majelis Ulama Indonesia – Indonesia Council of Ulama) fatwa permitting the use of the AstraZeneca vaccine despite the haram ingredients was considered an excuse for Muslims to administer non-halal vaccines. However, several parties disagreed on the fatwa because the emergency legal standing for its permissibility did not apply to all regions. The reason was that each had different rates of confirmed cases, ranging from high-risk areas to those with zero confirmed Covid-19 cases.

This study examines the Muslim community’s intention toward using halal vaccines in several regions in Indonesia. In addition, this study conducted in-depth interviews as samples in several regions. This study also conducted interviews to determine the public’s views on government obligation about the Covid-19 vaccine. Finally, this study proposes a vaccine to avoid the possibility of controversy over the use of non-halal vaccines.

The purpose of this research is to examine the effect of flow experience on mobile social networking service (SNS) users' loyalty.

Based on 305 valid responses collected from a survey questionnaire, structural equation modeling (SEM) technology was employed to examine the research model.

The results show that both information quality and system quality significantly affect users' trust and flow experiences, which further determine their loyalty. The results indicate that flow experience is the strongest determinant of users' loyalty.

Mobile SNS providers need to consider user experience when seeking users' loyalty. They should enhance information quality and system quality in order to improve user trust and flow experience.

Although much research has been conducted to explore the effects of extrinsic motivations, such as perceived usefulness, on mobile commerce user behavior, the effect of intrinsic motivations, such as flow experience, is seldom tested. This research found the effect of flow experience on mobile SNS users' loyalty to be significant.

The advancements of emerging technology to configure the way to convey information, knowledge sharing and even entertainment could make a valuable insight to the contemporary life trend. Because the increased new types of social network site (SNS) use would undoubtedly create the ethical issues referring to both positive and negative effects, it can lead to higher rates of the unintended consequences mentioned above and thus ethical issues surrounding SNS need to conceive an entire deal of attention. This paper aims to investigate the application of values and ethics on SNS.

Literature from refereed and peer-reviewed journals and articles was reviewed using thematic topic analysis to propose a model of ethics in SNS. In this paper, the profound conceptual discussions related to SNS use were examined in the way which these theories can be transformed into technical requirements and specifications. A review of the literature pointed to a need for ethical engagement with SNS.

The finding revealed that there are three points of adaptive ethics on SNS, which would entail enhancing awareness about the quality of information available. This followed with which ranged from credible to dubious, through increasing caution about information quality and reliability across the online social community.

In this paper, we have summarized the profound conceptual discussions related to SNS use both as users in engaging social relationship and brands’ promotion in dealing with customers’ transaction and examined the ways in which these theories can be transformed into technical requirements and specifications. Put simply, the author proposes a dynamic theory that encompasses credibility and conscientiousness, by way of confirmation, as the ultimate goal of SNS ethics as it pertains to information.
