This study investigated the various groups of factors that predict individuals’ use and non-use of fitness and diet apps on smartphones. Unlike previous research on fitness and diet apps which have mainly studied individuals’ intentions to use the apps, this study focused on the prediction accuracy of various factors that lead people to use fitness and diet apps through analysis of data collected from users as well as non-users of these apps. To examine prediction accuracy, this study applied the Random Forest algorithm. According to the findings, prediction accuracy higher than that of 70 percent was observed for nine factors: age, annual income, education, perceived obesity, dieting efforts, number of smartphone apps currently used, daily time spent with smartphone apps, perceived benefits from exercise, and social influence. A major contribution of this study is its detection of those factors predicting actual behavioral decisions regarding use of fitness and diet apps, as opposed to future intentions..  相似文献

China is the most rapidly aging country and has the largest aging population in the world. However, social participation is an important intervention to boost the active and healthy aging. The present study investigated the effects of media usage, together with social-demographics and health variables, on Chinese older adults. Drawing upon a national research project with a representative sample (N = 1,399) of older adults (55+) from 58 cities in China, the research findings revealed that conventional media, digital access and social media usage had positive effects on older adults’ informal social participation, while age moderated the relationship between informal social participation and digital access, particularly regarding access to tablet PCs and smartphones. Moreover, conventional media, digital access and social media engagement largely explained seniors’ formal social participation regardless of their social-demographic backgrounds. Finally, the roles of conventional media and digital media in older adults’ social participation are discussed.  相似文献

Social media has been increasingly utilized as an effective avenue for individuals to obtain needed social support and health-related information, especially during the on-going global COVID-19 pandemic. However, surprisingly few empirical studies have concentrated on the detrimental impact of social media adoption on young adults’ psychosocial well-being and mental health. Drawing upon previous stressor-strain-outcome theoretical paradigm (SSO), the present research investigates how psychosocial well-being assessments, especially compulsive WeChat use and information overload could trigger social media fatigue and, furthermore, how social media fatigue would ultimately result in emotional stress and social anxiety. This article utilized the cross-sectional design whereby statistical data were collected from 566 young people to test the conceptual research model. This research results demonstrate that perceived information overload through WeChat could significantly trigger social media fatigue among young people. Moreover, perceived information overload could indirectly predict emotional stress and social anxiety through the mediation of social media fatigue. This present work has vital theoretical and practical implications for widespread adoption of newly emerging communication technologies to enhance mental health and well-being among younger generation during recent public health crises.  相似文献

Infodemic, the spread of false information during the COVID-19 pandemic, has been raised as one of the major concerns aggravating the confusion in the global society. In this regard, the role of media as an information channel in delivering the reliable information and motivating the active participation of citizens in complying with government’s preventive actions becomes much more important. In this study, the role of online news and social media on people’s preventive actions considering the role of trust in citizens and government from the perspective of social capital is investigated. For the empirical study, a structural equation modeling is employed by using survey material gathered from South Korea in the early days of the COVID-19 outbreak. South Korea was selected as its COVID-19 prevention strategy focused not only on the provision of medical support, but also on the enhancement of social trust through active engagement with people through media channels. Our results reveal that the perceived characteristics of online news and social media influence preventive actions through the trust in citizens or in government. In addition, while online news media enhances trust in both the citizens and the government, social media only influences trust in citizens. Based on our findings, the role of media in preventing the spread of COVID-19 is dicussed.  相似文献

In many developing countries such as Saudi Arabia the adoption of cloud computing is still at an early stage. This research aims to investigate the influencing factors in the decision to adopt cloud computing in the private sector. An integrated model is proposed incorporating critical factors derived from a literature review, along with other factors (such as physical location) that have not been examined in previous studies as main factors in the organisation’s decision to adopt cloud services. Data were collected from 300 IT staff in different organisations in the private sector in Saudi Arabia, in order to test the cloud adoption model and explore factors that were positively or negatively associated with cloud adoption. The most influential determinants of cloud adoption were found to be quality of service and trust. However, security and privacy concerns still prevent cloud adoption in this country. This study also showed that the effect of these variables differed according to organisation size and in adopter and non-adopter companies. Overall, these research findings provide valuable guidelines to cloud providers, managers, and government policy makers on ways of encouraging the spread of cloud computing in Middle Eastern countries and increasing its implementation, particularly in Saudi Arabia.  相似文献

Social media, as a subaltern public sphere (Fraser, 1990), have a democratic function in providing an alternative platform for minorities and marginalized to defy mainstream discourses in the public sphere. However, social media have been found to have an echo chamber effect, which may be detrimental to democracy. They may help to accelerate the ascendancy of a “post-truth” era in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief. A study on political polarization, however, showed that selective exposure and avoidance in social media are weak indicators of polarization (Johnson et al., 2017). This study examines the role of social media in democracy and partisan politics. The authors considered that despite the echo chamber effect, social media have a limited part to play in the formation of polarized stances compared with other factors, such as demographics, political orientation, and mass media use. The study tested two main hypotheses: H1: Social media use is associated with political stance that is marginalized in the mainstream media; H2: Political orientation has a stronger relationship than social media use with the stance toward political values and social issues.The results supported both hypotheses. Social media are associated with political stance that is marginalized in the mainstream media. However, when compared with other factors, the relationship between social media and stance becomes less obvious. Although the echo chamber effect may reinforce the original stance, social media do not exhibit a strong relationship with the stance toward political values and social issues. Partisan orientation and use of partisan mass media are found to have stronger links with variations in stance. Social media, however, provide a subaltern public sphere for those excluded from the dominant public sphere, thus extending the public sphere to accommodate multiple opinions and perspectives.  相似文献

This study examined whether external factors, which are charity project, charity organization, Internet technology features and social network site (SNS) features influence people’s general attitude towards online donation and their intention to donate via SNS. An online survey was conducted based on the framework of factors influencing the intention to donate via SNS that was adapted from the literature review. Data from 258 respondents were used for analysis. Structural equation modelling was used to test the research model and hypotheses. The results indicated that the Internet technology features factor significantly contributes in influencing people’s general attitude towards online donation, and general attitude positively influences people’s intention to donate via SNSs. The full mediation effect of the general attitude towards online donation on the relationship between Internet technology features and intention to donate via SNS was found. However, charity project, charity organization, and SNS features were not significant factors in influencing people’s intention to donate via SNSs. The sample was limited to some Asian countries (preliminary Malaysia and South Korea). Thus, the results cannot be generalized to other countries. The findings suggest that non-profit organizations should focus on how to deal with the Internet issues, especially pertaining to security and privacy. Therefore, a mechanism for gaining donors’ trust to use the Internet, particularly in doing online transaction must be considered.  相似文献

Campaigns have increasingly resorted to Facebook because it has the highest number of users among social media platforms. The question as to whether Facebook is a more favorable choice of social media than a blog for political purposes must be addressed. In this comparative study, cross-sectional data collected in the 2009 and 2014 Taiwan local elections were used for exploring the differences among voter motivations, perceived credibility, and dependency between the use of political blogs and Facebook. In addition, the impact factors regarding the relationship between blogs and Facebook dependency were analyzed. The findings indicate that voter motivations, perceived credibility, and dependency were higher for political blogs than they were for Facebook, suggesting that in a political context, people prefer blogs to Facebook. The results of regression analyses indicate that the motivation for debating political topics was a significant predictor of the dependency on blogs, whereas motivations for general information and entertainment were related to Facebook use. The perceived credibility was not related to blog use; however, accuracy and information depth were significant factors for the use of Facebook. The reasons for the differences between peoples’ use of political blogs and Facebook are discussed in this paper. This study advances our understanding on the variations in people’s use of different social media platforms in a political context, and few studies have investigated this topic from a user-oriented perspective.  相似文献

There are a number of approaches to learning such as traditional approaches (teacher-centered) and collaborative approaches (learner-centered). Nowadays, the concepts of collaboration and social interactions are the major trends in education. Therefore, many researchers embrace these concepts to offer the educational field enhanced learning environments which are supported by communication and collaboration techniques. The adaptation causes the existence of varied approaches which are addressing the collaborative learning techniques. As a result, there is a need for a mechanism to study those approaches and highlight their eminence. The aim of this paper is to give a comprehensive overview about the state-of-art in collaborative learning, especially by integrating social media tools. To do so, the study adopts a classification framework based on four different views (subject, purpose, method, and tool). The framework has been used to compare ten collaborative e-learning approaches. The finding indicates the potential of all approaches in developing an online learning environment for remote collaborative learning despite the lack of fulfilling all the requirements highlighted in the four views.  相似文献

Social influence is an important research topic in the technology acceptance literature, in particular for social media. Prior empirical studies have for the most part employed social influence theory to investigate user intentions to continue with social media, while culture driven theories have been neglected. Rather than using social influence theory, we introduced guanxi theory to explore how guanxi social mechanisms (or processes) influence Chinese users’ continuance intentions in WeChat. Specifically, we developed a model that examines the role of guanxi as manifested by renqing, mianzi and ganqing in perceived usefulness, perceived enjoyment and continuance intention in WeChat. A survey research method was adopted to test the proposed hypotheses. This study found that ganqing has a positive impact on perceived usefulness and continuance intention. Mianzi exerts a negative effect on continuance intention but exhibits a positive effect on perceived usefulness. Renqing was found to have no significant impact on perceived usefulness and continuance intention. Our study advances the Technology Acceptance Model (TAM) by introducing guanxi-based constructs in a Chinese mobile social-messaging application context. Our study also offers alternative insights on guanxi-based social influence processes in the Chinese technology acceptance literature.  相似文献
