  The ongoing discussion regarding the utilization of individual research
performance for academic hiring, funding allocation, and resource distribution
has prompted the need for improved metrics. While traditional measures such as
total publications, citations count, and the h-index provide a general overview
of research impact, they fall short of capturing the continuous contribution of
researchers over time. To address this limitation, we propose the
implementation of the Kz index, which takes into account both publication
impact and age. In this study, we calculated Kz scores for 376 research
profiles. Kz reveals that the researchers with the same h-index can exhibit
different Kz scores, and vice versa. Furthermore, we observed instances where
researchers with lower citation counts obtained higher Kz scores, and vice
versa. Interestingly, the Kz metric follows a log-normal distribution. It
highlights its potential as a valuable tool for ranking researchers and
facilitating informed decision-making processes. By measuring the continuous
research impact, we enable fair evaluations, enhance decision-making processes,
and provide focused career advancement support and funding opportunities.
