“…Surgeons holding academic titles, whether substantive or honorary, had two-fold better indices than their NHS only contemporaries, which is in keeping with reports from other specialties allied with surgery. 5 Even so, significant variance was "For whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath." 24 Arguably, an article's real quality is best measured by the number of times it is cited elsewhere (not self-citation), but building citations takes time, and other faster valuations are welcome, which has lead to the emergence of alternative metrics, now termed ''altimetry''.…”

“…4 The h-index has gained rapid favor because of incorporating two traditional measures of research yield; publication number (quantity) and citations (quality). [5][6][7][8][9][10] An author has an index h, if h of their Np (number of publications) have at least h citations each, and their other articles (Np -h) have less than or equal to h citations.…”

Background: The Hirsch Index, often used to assess research impact, suffers from questionable validity within the context of General Surgery and consequently adapted bibliometrics and altmetrics have emerged, including the r-index, m-index, g-index and i10-index. This study aimed to assess the relative value of these novel bibliometrics in a single UK Deanery General Surgical Consultant cohort. Method: Five indices (h, r, m, g, i10) and altmetric scores (AS) were calculated for 151 general surgical consultants in a UK Deanery. Indices and AS were calculated from publication data via the Scopus search engine with assessment of construct validity and reliability. Results: The median number of publications, h-index, r-index, m-index, g-index and i10-index were 13 (range 0-389), 5 (range 0-63), 5.2 (range 0-64.8), 0.33 (range 0-1.5), 10 (range 0-125) and 4 (range 0-245) respectively. Correlation coefficients of rindex, m-index, g-index and i10-index with h-index were 0.913 (p <0.001), 0.716 (p <0.001), 0.961 (p<0.001) and 0.939 (p<0.001) respectively. Significant variance was observed when the cohort was ranked by individual bibliometric measures; the median ranking shifts were: r-index-2 (-46 to +23); m-index-6.5 (-53 to +22); g-index-0.5 (-24 to +13); and i10-index 0 (-8 to +11) respectively (p<0.001). The median altmetric score and AS-index were 0 (range 0-225.5) and 1 (range 0-10) respectively; AS-index correlated strongly with h-index (correlation coefficient 0.390, p<0.001). Conclusions: Adapted bibliometric indices appear to be equally valid measures of evaluating academic productivity, impact and reach.

“…The h-index was introduced in bibliometric analysis by Hirsch [44] to illustrate the scientific output of a country, organization, researcher, etc. Therefore, the h-index covers both the quantity (number of publications) and the impact (number of citations) [45][46][47]. The impact factor for journals was obtained from the Journal Citation Reports (JCR) © Ranking: 2014 [48].…”

BackgroundDengue is an important emerging and re-emerging arboviral infection globally as a rapidly growing and widespread public health problem, with transmission occurring in more than 128 countries in Asia, Americas, southeast Africa, western Pacific, and eastern Mediterranean regions. Therefore, the aim of this study was to characterize and quantify the scientific output of dengue research in Arab countries relative to that worldwide by using a bibliometric analysis.MethodsThe standardized search approach based on the use of the the keyword “dengue” in the title, abstract, and keyword field was used to get research output related to dengue at a global level. All data related to dengue were collected from the past to December 31, 2015.ResultsA total of 19,581 dengue-related documents identified in the Scopus database. The results show that the study of dengue exhibits an overall upward trend from 1872 to 2015 with peak publications in 2014. The leading countries in dengue research were the USA (4,709; 24.05 %), India (1,942; 9.92 %), Brazil (1,530; 7.81 %), Thailand (1,260; 6.43 %), the UK (1,129; 5.77 %), and France (1,087; 5.55 %). Only 226 (1.16 % of the overall global research effort in the dengue field) articles were published from the Arab region. The total number of citations for all publications was 352,710, with an average of 18.0 citations per publication. Furthermore, the h-index for all extracted data related to dengue research was 186. Kingdom of Saudi Arabia (KSA) was the most productive country in Arab region with 102 documents representing 45.1 %. Furthermore, the h-index for all extracted data related to dengue research was 27. The USA was Arab’s most main cooperative partner (46, 20.4 %), followed by India (36, 15.9 %).ConclusionsThe amount of literature related to dengue research has considerably increased over the last decade. This bibliometric analysis has demonstrated the leading role that the USA, India, Brazil, Thailand, the UK, and France play in dengue research. The Arab world produced fewer publications related to dengue with lower quality than other world countries.

This paper is to survey researchers’ efforts in response to the most number of criteria of lecturers’ performance into various domains, connecting the research insights from the literature into a consistent taxonomy, and figuring out the gaps on this vital research area. The fundamental search is relating to 1) personnel evalaution especially lecturer; 2) education-related; 3) criteria and applications (methods). Web of Science, ScienceDirect, and IEEE Xplore are reliable sources that can cover education and technical literature. The final number of studies is 78. Five articles are reviews to characterize the evaluation criteria for specific specializations. An another group (73/78) is research articles that include diverse evaluation criteria and domains. Most domains covered criteria, such as knowledge, skills, experience, and qualification.
