Understanding the Factors Influencing E-Government Adoption in Sri Lanka: An Integrated Model of UMEGA and Extended UTAUT2. Abeykoon, B.B.D.S.; Sirisena, A.B. The effective adoption of electronic government (e-government) services is crucial for enhancing public services, particularly in developing countries like Sri Lanka. Understanding the drivers that lead citizens to use and recommend egovernment services is essential for ensuring long-term engagement and diffusion. However, despite the significant investments in digital infrastructure, Sri Lanka continues to experience low adoption rates in the context of egovernment. The present study investigates the key factors influencing the adoption of e-government services among Sri Lankan citizens using an extended theoretical framework, which was developed by integrating the Unified Model of E-Government Adoption (UMEGA) and the extended Unified Theory of Acceptance and Use of Technology 2 (UTAUT2). The proposed model encompasses context factors: performance expectancy, effort expectancy, social influence, perceived risk, user factors: price value, facilitating conditions, hedonic motivation, habit, personal innovativeness in IT, trust in government, and system factors: perceived information quality, perceived system quality, perceived service quality. The study collected data from 100 respondents using a structured questionnaire, employing the convenience sampling technique. The model explained 42% of the variance in attitude, 59% in use behaviour, and 57% in intention to recommend. All the context factors significantly affected attitude, while price value, habit, facilitating conditions, and perceived service quality impacted use behaviour. Trust in government directly impacts on the recommendation intention of e-government services. The model disclosed acceptable model fit (SRMR = 0.057) and moderate predictive relevance (Q² = 0.44 for intention to recommend). The findings underscore the critical importance of system improvement, trust-building, and user engagement strategies to enhance peer-driven recommendation of e-government services. These strategies are essential in the Sri Lankan context to drive adoption and sustained use of governmental digital services.

A bibliometric analysis on evolution of military historiography. Abeykoon, B.B.D.S.; Kumar, P. The study of military history and the evolution of warfare spans over two millennia, yet significant gaps persist in comprehensively understanding its scholarly landscape. This study addresses these gaps by employing bibliometric analysis to systematically examine 538 journal articles published across 348 journals in the Scopus database between 2000 and 2022. Utilizing performance analysis and science mapping techniques, with tools such as VOSviewer, the study evaluates the contributions of 840 authors, key publication sources, and influential nations in this domain. The findings reveal trends and research clusters, highlighting areas of dynamic scholarly growth and identifying under-researched topics, including post-war impacts, imperialism, and military technology. These insights underline the need for deeper investigations into critical themes such as human experimentation, military sexual trauma, and simulation. By advancing bibliometric methodologies, this study provides a structured framework for future research in military history, fostering interdisciplinary exploration and practical applications.

Global military technology: A bibliometric analysis of trends and directions. Abeykoon, B.B.D.S.; Kumar, P. The global military establishment witnesses significant transformations and utilizing technological developments to enhance capabilities. Investing in and mastering military technology is crucial for protecting national interests and preserving strategic relevance on the international scene in an era of constantly changing threats. Thus, a comprehensive portrayal of this field is needed. But it is lacking from rigorous studies leveraging bibliometric techniques. To fill the gap, this research study used bibliometric techniques to examine 494 journal articles in the Scopus database published in 342 journals. The articles were authored by 780 authors and show a dynamic growth of the topic for the period. The methodology is based on performance analysis technique and science mapping technique in bibliometric analysis. The results explore the contribution to the domain in terms of authors, sources, and countries, and provide research areas need more attention which drives military technology. It is therefore imperative that many researches have been on topics such as artificial intelligence, drones, automation, technology adoption, unmanned aerial vehicles, robotics, technology forecasts, technology transfer etc. Also, the military technology researches should be advanced and aligned in future with areas such as environment protection, sustainable development, budget control, economics, environment, behavior, etc.
