A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that accounts exclusively for papers and citation metrics within the specific discipline of Business and Management. This ensures that the ranking accurately reflects a researcher’s influence and impact within their field rather than their overall scholarly output.
Scope of Research Examined
The ranking process examined a total of 279,971 scientist profiles identified from a variety of bibliometric data sources across all academic disciplines. Out of these, 21 scientists specializing in Business and Management in Portugal qualified for the ranking.
To be considered for inclusion, a scientist’s D-index needed to be at least 30, with the additional criterion that the majority of their top-tier publications—those contributing most significantly to their citation metrics—be in the Business and Management discipline. Awards and notable achievements within the field were also considered to provide a more holistic view of scholarly impact.
The D-index threshold is strategically set in increments of 10 relative to the estimated total number of scholars in each discipline. This approach ensures that the top 1% of leading researchers are consistently incorporated into the ranking, preserving a focus on excellence. Furthermore, a proximity threshold of 30% or less between a scientist’s general H-index and their D-index is implemented to confirm the disciplinary focus of their research profile.
Additional Verification Practices
The Research.com team recognizes that raw bibliometric data should never serve as an absolute or sole indicator of scholarly output quality. Consequently, all scientist profiles included in the ranking undergo meticulous manual verification. This process involves cross-correlating publication records against a broad array of trustworthy sources to ensure accuracy and complete representation of a researcher’s contributions.
While the number of publications in prestigious journals and conference proceedings does not directly influence the ranking position, it constitutes a valuable secondary indicator of scholarly impact and visibility within the Business and Management community.
Ultimately, the ranking is based on each researcher’s D-index derived from attributes collected primarily through OpenAlex and CrossRef. These platforms represent the most prominent and reliable bibliometric data repositories accessible to the global research community.
