Research Questions/Issue: In this bibliometric review of shareholder activism literature spanning 1983–2021, we pursue two objectives. Firstly, we investigate the degree of interdisciplinarity in the field, and second, we scrutinize publication trends, foundational knowledge, core topics, and emerging thematic trends, exploring the trajectory of shareholder activism research over time and providing a roadmap for future scholars. Research Findings/Insights: Systematic analysis of 1055 scholarly works reveals significant growth and a trend toward interdisciplinarity, though disciplinary silos persist. Shareholder activism is evolving beyond traditional, firm-level financial motivations to include sustainability-oriented goals, blending environmental, and social objectives with corporate governance concerns and financial interests. This shift signals broader engagement by diverse activist actors, strategies, and motivations, with a heightened emphasis on the long-term impact of shareholder activism. To capture this complexity, we advocate for research that emphasizes the intricate interrelationships among actors, objectives, strategies and outcomes, encouraging a redefinition of theoretical and methodological approaches. Theoretical/Academic Implications: Our analysis underscores the need for greater interdisciplinary engagement in shareholder activism research and highlights an expanding scope of topics, regions and theories. With growing scholarly interest in sustainability-oriented shareholder activism, jurisdictional nuances, and the emergence of new activist actors like index funds and individual investors, we anticipate continued theoretical and methodological diversity. Practitioner/Policy Implications: Policymakers and practitioners should adopt a holistic approach to shareholder activism, considering the multifaceted actors, objectives, and strategies involved. Evaluations of activist outcomes should account for both financial and non-financial impacts at the firm-, market-, and macro-levels.

The RSA (Rivest–Shamir–Adleman) cryptosystem is a widely used public-key cryptographic algorithm in information systems and computer applications. With the advancement of lattice theory, a technique known as the lattice-based method has emerged as a significant threat to RSA and its variants. This paper aims to conduct a bibliometric analysis of publications in the field of lattice-based attacks on RSA-type cryptosystems. The analysis is based on a dataset of relevant publications retrieved from Scopus and utilizes visualization tools such as CiteSpace and VOSviewer for a thorough overview. In order to understand the research developmental trajectory, we analyze the publication trends over the years, explore cooperation networks at various levels, including country/region, institution, and author, and assess the extent of collaboration, contribution, and productivity within the field. Additionally, author co-citation network and reference co-citation clustering are utilized to enable the identification of significant research achievements, cutting-edge developments, and structural framework. Furthermore, we conduct detailed analysis from a keyword perspective to identify research hotspots and emerging trends. The findings contribute to the existing body of knowledge on lattice-based cryptanalysis of RSA-type cryptosystems. Moreover, this bibliometric analysis serves as a valuable resource for identifying fruitful areas for further exploration and guides future research efforts.

This study explores the changing landscape of Open Banking-a financial services model where third-party providers get access through APIs to banking data for further innovation and customer experience improvements. The analysis is based on Scopus bibliographic data and relies on Biblioshiny and Citespace for the analysis of trends from 1999 to 2024. The main indicators analyzed include the dynamics of the annual scientific production, which increased after 2018 by a factor driven by regulatory frameworks such as PSD2. The main contributors are leading authors and sources, among them the Journal of Payments Strategy and Systems, while country-specific analyses definitely point out the UK, India, and China as major Open Banking research hubs. Thematic and trend analyses show that themes like data sharing, fintech, and API regulation are well-developed, whereas API security and risk management are still underexplored. Co-citation network visualizations depicted clear collaboration networks between countries and then between key authors. Factorial analysis further identified clusters of research related to technologically integrated themes, such as machine learning and blockchain. Key research gaps were identified in areas such as security and risk management, which are considered critical, with Open Banking’s continued expansion across the world. Practical implications include more robust API security frameworks and a deeper dive into the advanced technology-regulatory compliance link.
