Many studies have focused on the adoption of social commerce (s-commerce) by customers but not by businesses or by microbusinesses. Further, they have investigated this adoption from a researcher's perspective while using quantitative approaches. To fill this gap, the study sheds light on the success of Instagram for microbusinesses (IMB) in an Arab country and highlights the need for more investigation in order to understand this complex phenomenon. In this study, the authors use a qualitative approach to 27 microbusiness cases that adopted Instagram for s-commerce. They use technological innovation theories to successfully identify and classify the drivers and inhibitors of success under different contexts. Hence, they find that the success of IMB in Kuwait is contingent on addressing different technological, organizational, and environmental challenges. Further, they find that Instagram initiatives are still evolving and still need assistance from different stakeholders to overcome several hurdles. This study provides different recommendations that advance the theory and practice.

This is a cross-country study about intention to use mobile banking considering respondents from Brazil, South Korea, and the United States of America. The purpose of the paper is to analyze the role of an individual's computer self-efficacy ion mobile banking context. The authors employed the confirmatory factor analysis and the structural equation modeling to analyze the constructs and test the hypotheses of the study. They also relied on bootstrap confidence intervals to test the statistical significance of indirect effects. This study considers a comprehensive measure for computer self-efficacy (CSE), and a direct effect of this variable on two antecedents of behavioral intention to use mobile banking was found. CSE also had an indirect effect on the intention to use mobile banking. However, the effect of computer self-efficacy was not persistent among the different sub-samples considered in this study.

The influence of eWoM use for s-commerce in the context of Arab region remains unexplored. To bridge this gap, this study develops a model for eWoM use for s-commerce post adoption. This model link three antecedents-factors (trust towards other people, trust of internet/Instagram, and perceived risks) to eWoM use for s-commerce through the mediation of perceived enjoyment, perceived value, and customer satisfaction. The model is validated with a large sample of 843 Instagram users using LISREL tool. Research findings revealed that propensity to trust, trust of internet, perceived risk, and perceived value affect use of eWoM through the indirect effect of perceived enjoyment and satisfaction, while perceived value has no direct effect on eWoM. Customer satisfaction was a predominant predictor of eWoM use. The model has relevant contributions and implications for both research and practice.

What critical factors contribute to knowledge workers’ effective information management and consequent job performance? This paper begins to address this important question by developing a conceptual definition of a new construct called personal information management effectiveness (PIME) and its constituent dimensions. Specifically, we theorize that PIME consists of two underlying dimensions: personal information management motivation (PIMM) and personal information management capability (PIMC). Synthesizing the extant literature on information management and information orientation, we further conceptualize PIMM as having four sub-dimensions of proactiveness, sharing, transparency, and formality, and PIMC as possessing five sub-dimensions of sensing, collecting, organizing, processing, and maintaining. Moreover, we develop a theoretical model that positions PIME as a mediator between two selected individual characteristics (IT self-efficacy and need-for-cognition) and job performance. New measures for PIME dimensions were developed and shown to have strong psychometric properties. The proposed model was empirically tested using data collected from 352 knowledge workers. As theorized, PIME was found to have significant effects on job performance (41%) and fully mediate the effects that the selected individual characteristics have on job performance. Responding to recent calls for advanced research on personal information management, the measures of PIMM and PIMC developed in this study have practical value as research and diagnostic tools and the findings provide useful insights to help organizations improve knowledge workers’ information management practices.

Enterprise systems are gaining interest from both practitioners and researchers because of their potential linkages to organizational and individual user's productivity. Information systems (IS) researchers have been investigating the implementation and adoption issues of enterprise systems based on the organizational IS management perspectives. However, there are few papers that investigate enterprise systems management and implementation issues based on the informal control mechanisms, although the enterprise systems are control tools in the organization. Specifically, this paper applies Enterprise Resource Planning (ERP) adoption and implementation to the informal controls, such as cultural control and self-control, which can be viewed as a tacit perspective in knowledge management. Uncertainty avoidance and perceived enjoyment are used as informal controls in the ERP implementation in this paper, and are linked to the technology acceptance variables to investigate the relationships among them. Sociotechnical design, organizational control mechanism, knowledge management, and individual motivation are reviewed to support this potential linkage in the model. Field data via the online survey of ERP systems user group (n=101) are analyzed with partial least squares and supported our hypotheses. Uncertainty avoidance cultural control and intrinsic motivation as self-control are the important antecedents of ERP systems adoption. Furthermore, the result helps the systems manager understand that informal controls should be applied to the ERP systems implementation to enhance tacit and social aspects of IS management.
