Scopus publication, h-index, impact factor and Q1 publication
Research is the center of education, as research enables one to be a “knowledge producer”, instead of being merely “knowledge retailer”. The quality of research is measured by both quantity and quality (impact) of publication, which is highly preferable to be delivered in the form of international journal papers, with high quality. In Binus University, the performance of publication of each faculty members is monitored through Scopus.com, the world’s biggest database indexing data of peer-reviewed publications. At Scopus, an affiliation (either universities, research groups, or companies) may see the publication title, journal title, list of authors, the profile of a particular author, also when the publication has been indexed at Scopus, and how many citations obtained by a paper.
There is still a debate on how successful publication performance of a particular researcher/faculty member is measured, as there is a trade-off of quantity and quality of publication (where high quantity of publication often sacrifices the quality, and vice versa). At 2005, Jorge E. Hirsch suggested a type measurement that may assess both quantity and quality (impact) of publications simultaneously, which is by using h-index.
H-index of “n” is defined as “n” papers published by a particular scientist, that gets “n” number of citations. In other words, the higher the h-index, the more productive and the more meaningful a publication performance of a person. Better explanation on measurement of h-index could be by taking attention to the example below:
Let us take an example of publication profile of the Head of Department of Food Technology Binus University: Ibu Ir. Ingrid S. Surono, MSc, PhD
Her Scopus profile tells us that she has at least 19 papers indexed at Scopus, with various numbers of citations (sorted from largest to smallest), with h-index of 7.
Her h-index is not 8, unless her paper 2006’s and 2015’s paper get additional 1 and 1 citation, respectively. If you could grasp this, then you could perform another plot for Bu Ingrid’s deputy, pak Dave Mangindaan, https://www.scopus.com/authid/detail.uri?authorId=36621052200
The importance of h-index, at least for Indonesian scientist, is for enabling emerging scientist to submit proposals twice as many as their peer. In Indonesia, submission of research grants to the Indonesia Ministry of Higher Education is limited to 1 proposal as principle investigator and 1 proposal as a member. However, for those who have h-index more than 2, they are allowed to submit 2 proposals as a principle investigator and 2 proposals as a member, or in other words, maximum of 4 proposals!
Besides the impact of a publication as measured by the citation number, and thus related to the h-index, there is also a famous parameter named “impact factor” to measure the prestige of a particular journal. It is defined as the number of citations from all the articles published in journal X, divided with the number of articles released by journal X, within 2 years. So, with citation of 100 and 200, from 50 and 100 papers published by journal X, respectively, then the impact factor for journal X is 300/150= 2.0.
To maintain (or increase) the quality, an editor for journal X must be very selective, as a paper might be of subpar quality, thus not getting read and obtains no citation at all. However, the editor could not deliberately reject papers in order to maintain quality, as the number of published papers also must be at a sufficient quantity, otherwise the publication cost could be high and not economically feasible.
The common “Impact Factor” parameter is released and updated annually by Thomson Reuters https://jcr.incites.thomsonreuters.com/. However, due to the limitation of subscription, Binus University uses another source for measuring the quality of a journal, from http://scimagojr.com (Scimago Journal & Country Rank)
The quality parameter from Scimago is simply an index that is quite similar to that of Thomson Reuter’s, but not the same. At Scimago, journals are ranked by their respective fields, and separated into 4 categories, which are:
Q1 (top <25%)
Q4 (bottom >75-100%)
Some examples of Q1 journals are
- Journal of Agricultural and Food Chemistry (Bu Ingrid has a publication in it, at 2008, with 12 citations), with unbeatable Q1 reputation from 1997-2016 at two different fields of Agricultural and Biological Sciences, and Chemistry.
- Drying Technology
Our faculty member has a paper in it, Q1 at Chemical Engineering
Our faculty member has a paper in it, Q1 at Filtration-Separation, Materials Science, Physical and Theoretical Chemistry
