“…Our results are consistent with Bradford’s Law, which establishes that most articles of interest in an area are published in a small number of high-impact journals [ 13 ]. All T10 articles have been published in top quartile (Q1) journals of their respective areas of knowledge, including four in the New England Journal of Medicine .…”

Dimethyl fumarate is a cytoprotective and immunomodulatory drug used in the treatment of multiple sclerosis. We performed a bibliometric study examining the characteristics and trends of the top 100 cited articles that include dimethyl fumarate in the title. On 21 September 2020 we carried out an electronic search in the Web of Science (WOS), seeking articles that include the following terms within the title: dimethyl fumarate, BG-12, or Tecfidera. To focus our investigation on original research, we refined the search to include only articles, early access, others, case report, and clinical trials. We obtained a total of 1115 items, which were cited 7169 times, had a citation density of 6.43 citations/item, and an h-index of 40. Around 2010, there was a jump in the number of published articles per year, rising from 5 articles/year up to 12 articles/year. We sorted all the items by the number of citations and selected the top 100 most cited (T100). The T100 had 4164 citations, with a density of 37 citations/year and contained 16 classic research articles. They were published between 1961 and 2018; the years 2010–2018 amassed nearly 80% of the T100. We noted 17 research areas with articles in the T100. Of these, the number one ranking went to neurosciences/neurology with 39 articles, and chemistry ranked second on the T100 list with 14 items. We noticed that the percentage of articles belonging to different journals changed depending on the time period. Chemistry held the highest number of papers during 1961–2000, while pharmacology andneurosciences/neurology led the 2001–2018 interval. A total of 478 authors from 145 institutions and 25 countries were included in the T100 ranking. The paper by Gold R et al. was the most successful with 14 articles, 1.823 citations and a density of 140.23 citations/year. The biotechnological company Biogen led the T100 list with 20 articles. With 59 published articles, the USA was the leading country in publications. We concluded that this study analyzed the use of and research on dimethyl fumarate from a different perspective, which will allow the readership (expert or not) to understand the relevance of classic and recent literature on this topic.

“…Pointing once again to the emergence of the subject and the curve of interest by the scientific community, indicating that the average life has not yet reached saturation point. It also allows us to affirm with certainty that the rate of thinning or the substitution of scientific knowledge on this subject is still far from being initiated, in the same way as the aging/obsolescence factor, since there was no loss greater than 50% in the citations and in the actuality of the information [5,10,14].…”

“…Applying the Bradford's Law to verify the behavior of the distribution/dispersion of journals, in Table 3, it was possible to identify, from the Bradford Multiplier (Bm), a constant, since the variation between the Bm of the Zones remained within the allowed oscillation [5][6][7][8][9] 0.7, demonstrating a distribution very close to the ideal (I:n:n 2 ), as determined by the Law. The Nucleus comprised 15 periodicals, being these the most devoted to the subject [9][10].…”

“…We have experienced a century in which information is published and disseminated at an unprecedented scale and speed, making the process of incorporation by researchers increasingly easy [3], therefore, it is essential to have the minimum ability to select the best indexing bases and repositories, prospecting, filter and select the most relevant information for their research, and it is precisely in this context that bibliometric studies present themselves as sources of information for different research areas, and are capable of subsidizing technological and scientific evolution [4], however, due to their characteristic of mapping scientific production [5].…”

Objective: To analyze the dispersion of journals and scientific collaboration on Severe Acute Respiratory Syndrome, available on the Web of Science. Methods: Bibliometric study that analyzed the production of documents available on the Web of Science, from 1989 to 2020. Results: 1623 documents were retrieved, distributed in 538 journals. The average production per year was 55.9. The average production per author was 1.73. The Nursing category contributed 17 (1.04%) documents, with Virology being the largest contribution 324 (19.96%). China led the ranking with 640 publications (39.43%). Conclusion: The data presented demonstrate the high level of interest of the scientific community in the subject. It was possible to identify 82 authors composing an Elite group of Authors, whose productivity was 66.1%. The United States, China and Saudi Arabia are the countries that most formed Collaboration Networks

“…This was performed by using word frequency analysis (WFA) through NVivo, which gave us the number of times a word was used in the entire sample set of learner's feedback. The more frequently a word was used in the feedback, the bigger was its size in the word cloud (Figueiredo et al, 2019).…”

In recent years, sentiment analysis has gained popularity among researchers in various domains, including the education domain. Sentiment analysis can be applied to review the course comments in Massive Open Online Courses (MOOCs), which could enable course designers’ to easily evaluate their courses. The objective of this study is to explore the influential factors that affect the completion rate of MOOCs and unravel the sentiments of dropout learners by evaluating learners’ feedback. In the present study, sentiment analysis was performed using Python programming and NVivo tools on the feedback of the learners enrolled in three MOOCs entitled Introduction to Cyber Security, Digital Forensics and Development of Online Courses for SWAYAM, which was hosted on the SWAYAM platform (www.swayam.gov.in). Two instruments were used for data collection: (1) a structured questionnaire using a 5-point Likert scale was administrated using Google Forms — the questionnaires have also some additional open-ended questions — and (2) semi-structured interview schedules with the domain experts. The feedback was collected using Google Forms and a total of 324 responses were received between April 23, 2022 to May 31, 2022. The non-probability sampling method served as the sampling approach in the quantitative phase in this study. During analysis, the findings of the feedback uncovered important dimensions of some peculiar factors that may be responsible for retention of learners, i.e., content localisation, credit mobility and latest trend courses that were less explored in the earlier literature.
