A scientist’s position in this ranking is determined by their D-index (Discipline H-index), a refined metric which considers only publications and citations relevant to the specific discipline under examination—Business and Management in this instance. This targeted approach ensures that the ranking reflects a researcher’s true impact and contribution within their specialized field, rather than their general academic performance.
Scope of Research and Eligibility Criteria
The ranking framework comprehensively examined 279,971 scientist profiles spanning all academic disciplines, including a focused analysis on top researchers within Business and Management, identifying 3 leading scientists specifically in this area for Ghana.
To qualify for inclusion, candidates were required to meet a minimum D-index threshold of 30 within the discipline, thereby ensuring a baseline of established research impact. Additionally, a majority of the candidate’s tier publications had to be within Business and Management, reinforcing the focus on relevant and specialized contributions. Consideration was also given to notable awards and achievements in Business and Management to complement the bibliometric evaluation.
The D-index cutoff for top researchers is dynamically adjusted in increments of 10 relative to the estimated total scholar population within each discipline. This adaptive threshold guarantees that the ranking consistently includes the top 1% of leading experts in the field. Another important criterion applied was that the proximity between a scientist’s overall H-index and their D-index should not exceed 30%, ensuring that their general academic footprint closely aligns with their discipline-specific impact.
Verification and Methodological Rigor
At Research.com, we recognize that raw bibliometric data alone cannot provide a complete evaluation of scholars’ outputs. To address this, all scientist profiles included in the ranking underwent thorough manual verification. Profiles were cross-correlated against an extensive array of trusted publication sources to authenticate accuracy and relevance.
While the number of papers published in prominent journals and esteemed conference proceedings is not a direct factor in determining position within the Research.com rankings, it is acknowledged as a valuable secondary indicator of a researcher’s contributions within their scientific area.
The ranking’s foundational metric—the D-index—is derived using the meticulously curated data from OpenAlex and CrossRef, which stand as two of the most comprehensive, respected, and widely-accessible bibliometric databases available to the global research community.
