The competitiveness and sustainability of employees in service and nonservice-based organizations continue to trigger scholars' interest to investigate the related factors. As per the review of literature, there are only a few studies have been conducted on abusive supervision and intrinsic motivation about employee psychological wellbeing and turnover intention. We applied the social exchange theory to abusive supervisors at the workplace. This study, therefore, explores the direct and indirect relationship between abusive supervision on subordinate psychological wellbeing and turnover in service-based organizations. This empirical study employs a quantitative research methodology to establish the mediating influence of intrinsic motivation between the underlying constructs. Out of 300

Due to the emergence of Web 2.0 and consequently the increased use of social media, this study aims to explore the role of social media in changing the behavior of tourists and the choice of a destination. Despite the massive popularity of social media, the studies with a comprehensive set of driving constructs along with indicators of social media regarding the changing behavior of tourists are lacking in the literature. Therefore, framed by the theory of planned behavior (TPB), the present study fulfills this research gap by developing a set of driving constructs and carrying out an empirical analysis by collecting data from millennials in the selected universities of the Czech Republic. Through the non-random sampling technique, precisely convenience sampling, 261 valid responses were received, and partial least squares-structural equation modeling (PLS-SEM) analysis was performed to achieve the objectives of this study. The results indicate that social media channels have a significant impact on behavioral intention and the actual behavior of tourists (significant direct and indirect effect). The constructs tourist information search and tourism promotion were partially supported toward predicting the behavior of tourists. Control–variables related to socio-economic characteristics such as gender and educational level also have a significant impact in determining the actual behavior of tourists. Hence, overall, the study concludes with the significant and considerable impact of social media on the behavior of tourists. The contributions of the study and future directions are discussed at the end of the paper.

The upsurge in social media websites has in no doubt triggered a huge source of data for mining interesting expressions on a variety of subjects. These expressions on social media websites empower firms and individuals to discover varied interpretations regarding the opinions expressed. In Sub-Saharan Africa, financial institutions are making the needed technological investments required to remain competitive in today's challenging global business environment. Twitter as one of the digital communication tools has in recent times been integrated into the marketing communication tools of banks to augment the free flow of information. In this light, the purpose of the present study is to perform a sentiment analysis on a large dataset of tweets associated with the Ecobank Group, a prominent pan-African bank in sub-Saharan Africa using four different sentiment lexicons to determine the best lexicon based on its performance. Our results show that Valence ABOUT THE AUTHORS Raphael Kwaku Botchway is a Ph.D. candidate with research interest in Soft Computing, Social Media and Text Analytics at the Faculty of Applied Informatics, Tomas Bata University in Zlin, Czech Republic.

Online shopping has become increasingly popular in the past two decades. Yet, despite its popularity, the use of online stores on the African continent pales in comparison to other parts of the world. Moreover, in many economic contexts in Africa and including Ghana, there has been very limited research on the subject of online adoption and in particular, the fundamental factors that can influence its initial adoption, especially among young and relatively educated consumers who constitute the largest demographic group there. We, therefore, make a determined effort to fill this growing knowledge gap by exploring some fundamental factors associated to shop online by young and educated consumers. This exploratory research draws on the stimulus-organism-response (SOR) framework and focuses on five variables of interest namely perceived ease of use, government support infrastructure, and economic considerations about pricing, perceived convenience and use intentions of online retail stores. Evidence collected from 294 research participants provides support for our research propositions Finally, our research contributions and future study directions are considered in the concluding part of the paper.
