In the contemporary era of global and sustainable information management, blockchain has made a cutting-edge transformation in online learning. To apprehend this new trajectory, this current systematic review with bibliographic visualization aims to identify the thematic clusters of underlying aspects concerning the sustainable nexus of blockchain and online learning. Using the updated guidelines of the PRISMA flowchart, a total of 434 scholarly research papers from the mainstream research databases, i.e., Web of Science, Scopus, IEEE Xplore, and ScienceDirect, were inspected to be categorized into 15 relevant publications. Bibliographic data were assembled and analyzed accordingly to construct network visualization maps, such as co-authorship, citation, co-citation, bibliographic coupling, and term co-occurrence using VOSviewer 1.6.18. Significant terms were reported and later cross-mapped with those identified by critically reviewing the applicable 15 papers. Standardized scholarship, behavior pattern, and digital badging have been found and derived as themes from the connected clusters. Therefore, current research findings reveal these three broad clutches of themes concerning the sustainable nexus of blockchain and online learning.

Drawing on social identity theory, this study seeks to investigate the relationship between green organisational climate and employee engagement facets, such as vigour, dedication, and absorption. The research also explores the mediating effect of green group cohesion and the moderating effect of technological turbulence. A two-wave survey was administered to gather data, which were analysed utilizing partial least squares structural equation modelling. The findings indicate that green organisational climate does not consistently affect the vigour, dedication, and absorption of Gen Z employees unless green group cohesion is present. The results further demonstrate that technological turbulence serves as a significant moderator, exerting a negative impact on the relationship between green organisational climate and both vigour and dedication. This study offers novel insights that explain how green group cohesion positively mediates the influence of green organisational climate on employee engagement dimensions. The theoretical and practical implications are discussed, followed by research limitations and future avenues.
