Purpose This paper aims to investigate the key drivers of social media adoption intention by small- and medium-sized enterprises (SMEs). Design/methodology/approach It uses a multi-perspective framework combining technological, organizational and environmental elements affecting SMEs. Data were collected from a random sample of 1,700 SMEs operating in the UAE. Partial least squares structural equation modeling was used to analyze the data. Findings The results showed that the technology construct had no significant effect on social media adoption, but both organization and environment constructs were significant. Research limitations/implications This has implications for social media experts and anyone wishing to encourage social media use by SMEs. Originality/value Conceptually, it develops a suitable multi-perspective framework covering various factors that may affect social media use. It also tests the framework empirically on a sample of SMEs from the UAE.

Abstract Eighteen earlier studies have investigated the associations between social media use (SMU) and adolescents’ self-esteem, finding weak effects and inconsistent results. A viable hypothesis for these mixed findings is that the effect of SMU differs from adolescent to adolescent. To test this hypothesis, we conducted a preregistered three-week experience sampling study among 387 adolescents (13–15 years, 54% girls). Each adolescent reported on his/her SMU and self-esteem six times per day (126 assessments per participant; 34,930 in total). Using a person-specific, N = 1 method of analysis (Dynamic Structural Equation Modeling), we found that the majority of adolescents (88%) experienced no or very small effects of SMU on self-esteem (−.10 < β < .10), whereas 4% experienced positive (.10 ≤ β ≤ .17) and 8% negative effects (−.21 ≤ β ≤ −.10). Our results suggest that person-specific effects can no longer be ignored in future media effects theories and research.

We examined the impact of social media use on employee innovative performance, and the psychological mechanism underlying this relationship. Our hypothesis was that social media use would have a positive influence on employee innovative performance and that work engagement would act as a mediator in this relationship. We employed structural equation modeling to investigate this mediating role with 298 employees of a large enterprise in China. Results of a time-lagged survey showed that both social media use and work engagement were significantly correlated with innovative performance, and work engagement partially mediated the social media use–innovative performance relationship. These findings shed light on how social media use affects employee innovative performance. Theoretical and practical implications and directions for future research are discussed.

Today, social media have become a major trend, and consumers are engaging more and more in the social media platforms used by hotels. This does not mean that they book a hotel room via social media, as the booking process is a complex one. The paper investigates the factors that affect users’ intention to book a hotel room using social media applications. The recent enforcement of General Data Protection Regulation (GDPR) in the European Union and California Consumer Privacy Act (CCPA) in California may have an impact on consumers’ behavior. To investigate this further, the study integrates into a model the following constructs: Perceived ease of use, perceived usefulness, trust in online hoteliers, social media use, and permission-based-acceptance. The survey was conducted on Greek users of social media. An online questionnaire was used for data collection. The conceptual model was tested using Structural Equation Modeling (SEM) analysis. The study identified four factors that directly or indirectly influence consumers’ intention to book hotel rooms through social media. Usefulness directly affects intention to book online. Permission-based acceptance plays a core role in the model. Both constructs trust in online hoteliers and social media use, and have a direct positive effect on permission-based acceptance, whereas permission-based acceptance has a direct positive influence on intention to book through social media. The validated model stretches the need for hoteliers to obtain permission from consumers in carrying out their marketing activities. It is important for hotel owners, managers, and social media specialists to keep consumers in mind, offer them useful information and services, and have a trustworthy behavior in order to boost bookings through social media.

Abstract There are mixed findings as to whether social media use (SMU) is positively or negatively related to well-being (positive/negative affect), and this relationship varies by age. The current study seeks to further explore this relationship by examining physical activity (PA) as a potential mediator at both a within (intraindividual) and between-person (interindividual) level across adulthood. The data are from the Midlife in the United States Refresher eight-day daily diary study (N=782, ages 25-75) with self-reported frequency of SMU, PA, and well-being (positive/negative affect). Multilevel structural equation modeling simultaneously tested how the relationships between the variables differed at both the between- and within-person levels. Between-person results showed that across the week, those who reported less SMU reported engaging in more PA, and more PA was associated with more positive affect. PA significantly mediated the relationship between SMU and positive affect for midlife and older adults, but not for younger adults. Effects for negative affect were not significant. Within-person results indicated that days with more PA were associated with more positive affect; however, PA did not mediate the relationship between SMU and positive or negative affect. These findings suggest the benefits of engaging in PA on one’s positive emotional well-being at both the between- and within-person levels. However, for midlife and older adults, more SMU across the week may take away time from engaging in PA, which in turn lowers their positive affect. Implications of the effects of SMU on PA and well-being across adulthood are discussed.

Fostering student creativity is widely accepted as an important goal in Chinese higher education, and social media is now integrated into students' everyday lives. I investigated how social media use in study contexts is related to students' engagement and creativity. A validated questionnaire was used to collect data from 652 undergraduate students at 3 Chinese public universities. Structural equation modeling results show that social media use in study contexts was related to student engagement and creativity, and that student engagement partially mediated the relationship between social media use and student creativity. This provides insight into how to promote student creativity. Theoretical and practical implications of the results are presented, and future directions for research are discussed.

Social media is becoming a platform for student entrepreneurship; however, little is known about the influence of social media use on students' entrepreneurial intention. This study investigated social media use as a predictor of students' entrepreneurial intention, with consideration given to the mediating role of self-efficacy. Questionnaires were given to undergraduate students at three Chinese public universities, and 524 effective responses were received. We used structural equation modeling to test our hypotheses. The results show that social media use was indirectly related to students' entrepreneurial intention via self-efficacy. Our findings extend the literature on the social media use–entrepreneurial intention link, and highlight the importance of self-efficacy in this link. Thus, educators could endorse social media tools and encourage students to incorporate these into their entrepreneurial activities.

We examined employee voice as the mediator in the social media use–employee innovative behavior relationship in the current Web 2.0 age. We used structural equation modeling to test this mediating role with 178 employees of a large enterprise in China. The results showed a significant positive relationship between social media use and employee voice, and between employee voice and innovative behavior, and a positive but not significant relationship between social media use and employee innovative behavior. Results also supported a full mediating role for employee voice in the social media use–employee innovative behavior relationship. Our findings extend prior research and suggest some mechanisms of social media use. Theoretical and practical implications are discussed.
