“…fj =number of articles with j authors j = articles (1 author, 2 authors, 3 authors, 4 authors, and more than 4 authors) N = number of articles K = The greatest number of authors in a paper (Ajiferuke, Burell, & Tague, 1988) Results In Table 1, the authors are sorted according to their number of publications. The rate of collaboration among prolific writers in the field of e-learning is bold and significant; few articles are single-authored, while the number of articles with four or more authors is remarkable.…”

Partnership is one of the mechanisms of scientific development, and scientific collaboration or coauthorship is considered a key element in the progress of science. This study is a survey with a scientometric approach focusing on the field of e-learning products over 10 years. In an Advanced Search of the Web of Science, the following search formula was used: TS=("m-learning" OR "mlearning" OR "mobile learning" OR "online learning" OR "virtual learning" OR "distance learning" OR "electronic learning"). The study was limited to [2005][2006][2007][2008][2009][2010][2011][2012][2013][2014], and the document type was limited to paper. A total of 4292 documents were found, to which 12362 authors contributed. The articles were evaluated individually and their information was entered into Microsoft Office Excel 2007 for analysis using the collaborative coefficient formula. In the Computers and Education journal, articles with two authors are the most frequent. The United States, with the highest production of articles in the field of e-learning, tends to produce articles with two authors. In 2014, the most productive year, articles with three authors were more frequent. The highest collaborative coefficient is in 2005 and 2014. Our findings show that despite the need for research activities as a team, the authors in the field of e-learning tend to publish their papers alone or in a team of two.

“…Co-authorship was measured by collaborative coefficients. 28 Despite the promise of MEDLINE regarding covering third world science more comprehensively than other databases, a crucial aspect of current international science politics relates to the selection of journals indexed in national databases. National databases tend to give more preference to their national sources, and this often amounts to some advantage when evaluation of publications of their national scientific activities is carried out.…”

This article maps the biomedical literature of Nigeria by source/origin of publications and authorships from 1967 to 2002. This mapping is expected to provide crucial information to both government and others taking funding and related decisions regarding biomedical research in Nigeria. Data was collected from MEDLINE. Scientists publishing on Nigerian biomedicine have written 6,820 articles in 295 journals/sources. Only eight of the 121 local journals that published biomedical research in Nigeria during the period were included in MEDLINE's listing (2.72%), while there were 32 (10.84%) regional and 255 (86.44%) external journals used. Local journals appeared to be more heavily used than regional and external ones. It was also shown that MEDLINE does not adequately represent Nigeria's biomedical literature.

“…3 shows that the value of CC above 0.5 in every year and it is exponentially increasing. According to Ajiferuke 18 , CC tends to zero as single authored papers dominate and higher the value of CC, higher the probability of multi and mega authored papers. This implies that papers published by BHU are more in collaboration and collaboration pattern is continually increasing with years.…”

Research and Development Organisation with 280 publications. BHU's main collaborator country is USA with 607 publications, followed by Germany with 471 publications. Maximum consistency (0.40) in international collaboration is seen with Nepal, whereas minimum consistency observed with England. Maximum consistency of publications is seen 1995. Highest consistency (0.37) is seen in sub-field electrochemistry. Sepectrochimica acta Part A has highest consistency (0.53), while Astrophysics and Space Science has lowest (0.19) consistency.Keywords: Three-dimensional study; Banaras Hindu University; BHU; Collaboration Received : 09 August 2017, Revised : 03 September 2017 Accepted : 19 September 2017, Online published : 07 November 2017 DJLIT, VOL. 37, NO. 6, NOVEMBER 2017 404 indicated volume; the quality (or impact i), as measured by the ratio C/P, where C is the total number of citations received by P papers, indicated the velocity with which the ideas in P papers are communicated through citations C, and consistency ƞ indicated the variety (variability) in the quality of the individual papers in the publication set or, in other words, the shape of the distribution curve. By using all three components together, a z-index can be computed from an energy-like term (Z = ƞ X = ƞ 2E ) as z = Z 1/3 , which has the same dimensions as the number of publications. X is energy and E is energy [5][6] , so it is possible to imagine a phantom indicator named zynergy for Z = ƞ X = ƞ 2E . This phantom index combines quantity, quality, and consistency (or efficiency) in the true spirit of 3D evaluation. The accurate calculation of consistency (ƞ) requires the complete citation sequence, (i.e. the distribution curve) for country, organisation, author or journal. tHrEE-dIMEnSIonAL EVALuAtIon tooLSSeveral indicators have been used to express performance of scientific output of an individual, institution, or an entity. Scientific performance of individual or an entity can be measured by using different parameters. QuantityNumber of papers/articles 'P' published during a prescribed window will be called publication window (for this study the window is from 1989 to 2016). A five-year citation window is considered for each year. Quality and consistencyQuality denotes citation per paper, calculated as C/P where C is the number of citations during a prescribed citation window. The quality measurement needed two separate windows, the publication window and the citation window. In 3-D evaluation of performance measurement after computing quantity P and quality i parameters, it is possible to derive other indicators by following these sequences. P= i 0 P (zero th -order indicator), C= i 1 P (first-order indicator), X= i 2 P = iC (secondorder indicator), where C = Σc j , j = 1 to P.C is derived from complete citation sequence, c j of the citation of each paper in a publication portfolio of P papers as the total number of citations, C=∑c j , for j=1 to P. Both P and C serve as indicators of performance in their respective ways. If C=iP may be as...
