Leaders play a critical role in the success or failure of their organizations. Leaders can be effective in implementing changes, building their organization's capabilities, and improving its performance, or the opposite, they could be ineffective. In this systematic review, the authors aim to summarize the findings of previous quantitative research, published between the period from 2000 to 2018, to identify the effect of various leadership styles on organizational Knowledge management (KM) capabilities and activities. The authors reviewed 50 articles found in well-known databases included Emerald, ScienceDirect, Taylor and Francis, Ebsco, Google Scholar, and others, concerning the impact of leadership when implementing KM in business organizations. The review revealed that transformational, transactional, knowledge-oriented leadership, top executives, and strategic leadership have evidence of their constant and positive effect on the KM process. The authors encourage organizations to use a combination of those styles to maximize the effect of leadership on KM. The authors also recommend conducting further studies on the effect of the remaining leadership styles, such as the ethical and servant leadership styles on KM and the other specific KM activities.

The concept of Green Information Technology (Green IT) has been widely discussed in recent times, but the question of how a firm can afford to implement Green IT in both IT and other business operations has yet to be examined. In addition, the question of whether Green IT has made any significant contributions towards competitive advantage in organizations has not yet been studied. This study attempts to bridge this gap by viewing Green IT capability from the lens of Natural Resource-Based View. The two constructs derived from this theory, namely, as pollution prevention and product stewardship are discussed in this paper. Its application is extended into the IT context with reference to Green IT literature. This occurs among an early review of the utilisation of these constructs particularly for Green IT process management. The implications of the outcome of this study, both for the IS researchers and for the practicing managers, are discussed.

Knowledge sharing is considered to be an essential concept and a determinant of success regarding knowledge management. The current paper reviews the most relevant quantitative studies, within the context of individual-level knowledge sharing. The main aim of this paper is to identify the relevant individual factors that influence knowledge sharing. Furthermore, it seeks to identify relevant theories, previously used in literature, that communicate a theoretical understanding of individual levels of knowledge sharing. The researchers searched through five well-known databases using a combination of keywords related to the study context. By applying filtration procedures to the articles gathered from the selected databases, the literature survey revealed 31 most relevant articles. As a result of reviewing the selected articles, it has been indicated that the factors that most affect knowledge sharing include trust, reciprocity, self-efficacy, altruism, and reputation. These factors, studied through different contexts, have been found to significantly affect the behavior of individuals in terms of sharing knowledge. Furthermore, it has been found that the social exchange theory has been repeatedly used. It has been concluded that the resulted antecedents may influence the knowledge sharing of individuals and consider these factors by the decision makers will motivate the individual’s intention to knowledge sharing.

PurposeThe aim of this paper is to review the firm's resources, as identified by the researcher in previous environmental studies, from the theoretical lens of a resource‐based view (RBV). This will help to identify the firm's resources for the future Green IT studies.Design/methodology/approachThe objective was first achieved by reviewing the environmental resources for the firm's performance. The approach uses literature reviews of environmental studies having related keywords in literature databases. Using content analysis approach, the authors selected ten empirical environmental studies and developed the typology of the firm's environmental resources. The frequently highlighted constructs are then discussed in the context of Green IT.FindingsThis review shows the importance of continuous innovation, stakeholder integration, shared visions and early adoption which were frequently highlighted in RBV studies. The literature studies concerning Green IT also point out the importance of these resources for Green IT performance. Drawing upon this, it is also believed that these firm resources identified from environmental literature are also applicable in Green IT context.Research limitations/implicationsSome limitations of this study have been encountered and are as follows: First, the search was performed within a limited time frame. Second, different search terms might have yielded more results. Third, the classification of the firm's resources might be different from the point of view of others. Nonetheless, the authors believe this review can be used as a guide for future integrative resource‐based Green IT studies. Future confirmatory studies could empirically validate these relationships. The role of mediating and moderating variables that could enhance Green IT practice can also be further investigated. This could contribute to the knowledge concerning the application of RBV in the Green IT context.Originality/valueThe paper helps to shed light on a firm's resources for environmental capability coming from different industries, which contributes towards an understanding of these theories from wider perspectives, including environmental sustainability, in the IT context.
