Research Productivity among Plastic Surgeons in the State of Israel: h-index and M-quotient Assessment

The h-index has been proven in the US and Canada to be a solid tool to assess the quality and impact of individual scientific work in the field of plastic surgery. M-quotient is an additional metric that mitigates the h-index's inherent bias toward more seasoned researchers. The objective of this study was evaluating the relationship between h-index and M-quotient and research productivity among plastic surgeons in the state of Israel.

Methods

A list of all Israeli board-certified plastic surgeons registered in the Israeli Society of Plastic and Aesthetic Surgery was obtained from the organization's website. Relevant demographic and academic factors of each surgeon were retrieved. The Scopus database was queried to determine each surgeon's h-index and M-quotient, among other bibliometric parameters.

Results

Our study included 173 plastic surgeons, 90% of whom were men. In total, 49.7% were working in academically affiliated hospitals; 14.4% of the surgeons had an academic rank. The mean h-index was 6.13; mean M-quotient was 0.27. Statistical analysis demonstrated a positive correlation between total number of publications (P < 0.0001), total number of citations (P < 0.0001), the surgeon's seniority (P < 0.0001), academic rank (P = 0.007), appointed as past/present plastic surgery department director (P < 0.0001), and working in an academic affiliated hospital (P < 0.025). The same parameters were found to have a positive correlation with M-quotient.

Conclusions

The h-index is an effective measure to compare plastic surgeons' research productivity in Israel. M-quotient is an ancillary tool for the assessment of research productivity among plastic surgeons, with the advent of neutralizing the surgeon's seniority.

Do researchers know what the h-index is? And how do they estimate its importance?

The h-index is a widely used scientometric indicator on the researcher level working with a simple combination of publication and citation counts. In this article, we pursue two goals, namely the collection of empirical data about researchers’ personal estimations of the importance of the h-index for themselves as well as for their academic disciplines, and on the researchers’ concrete knowledge on the h-index and the way of its calculation. We worked with an online survey (including a knowledge test on the calculation of the h-index), which was finished by 1081 German university professors. We distinguished between the results for all participants, and, additionally, the results by gender, generation, and field of knowledge. We found a clear binary division between the academic knowledge fields: For the sciences and medicine the h-index is important for the researchers themselves and for their disciplines, while for the humanities and social sciences, economics, and law the h-index is considerably less important. Two fifths of the professors do not know details on the h-index or wrongly deem to know what the h-index is and failed our test. The researchers’ knowledge on the h-index is much smaller in the academic branches of the humanities and the social sciences. As the h-index is important for many researchers and as not all researchers are very knowledgeable about this author-specific indicator, it seems to be necessary to make researchers more aware of scholarly metrics literacy.

Scientific Performance and Mapping of the Term STEM in Education on the Web of Science

Technological progress is causing terms such as “STEM”, an acronym for Science, Technology, Engineering and Mathematics, to burst into the educational arena, marking a new era in the application of innovative and motivating teaching and learning processes. The objective of this research is to analyze the trajectory and the transcendence of the “STEM” concept in the educational field, having as reference the reported literature of Web of Science. The methodology applied in this research is based on bibliometrics, analyzing both the performance and the structural and dynamic development of the concept through a co-word analysis. The total number of documents analyzed is 4390. The results show that the scientific community mainly uses English and research papers to present their results. From 2015 onwards, the main lines of research are beginning to be established, which focus on “women” and “science”. It can be concluded that the term “STEM” in education is beginning to have a greater incidence and impact on the processes of teaching and learning, especially in the field of science, although there are currently discrepancies between men and women in its use.
