This study examines the publication pattern of open access (OA) and paywalled scholarly works, determines the citations and views impact of publications published through the different forms of OA, and disaggregates the scholarly outputs and impact across the different types of OA in sub-Saharan African countries, in order to assess whether the types of OA matter in research impact in sub-Saharan Africa. Data from the SciVal database, utilising bibliographic, citation, and views data drawn from Scopus, formed the foundation of this study. The research scope encompassed documents published over a decade, from 2012 to 2021. Research output, quantified as the number of publications papers), constituted the primary focus, while citation-based and views-based metrics were utilised as proxies for measuring research impact. The findings underscore a steady rise in OA scholarly publications, indicating a growing inclination and uptake of OA scholarship within sub-Saharan African nations. Across most sub-Saharan African countries, OA publications comprised over 50% of the total publications. The study discerns a preference hierarchy for OA models: Green OA emerged as the foremost choice, trailed by Gold OA, and Bronze OA, while Hybrid-Gold OA registered as the least favoured model. Notably, publication counts exhibited robust associations with citation and viewing figures, displaying varying strengths in correlation with other citation and viewing metrics.

This research arises from the demand in business management for capabilities that put into practice—in an autonomous way—skills and knowledge in BI&A of all those who make decisions and lead organizations. To this end, this study aims to analyze the development of scientific production over the last 20 years in order to provide evidence of possible gaps, patterns and emphasis on domains of strategic leadership competencies in BI&A. The study was split into two methodological phases. Methodological Phase 1: Application of analytical techniques of informetrics. Methodological Phase 2: natural language processing and machine learning techniques. The records collected were 1231 articles from the Web of Science and Scopus databases on 16 August 2021. The results confirm, with an r 2 = 96.9%, that a small group of authors published the largest number of articles on strategic leadership competencies in BI&A. There is also a strong emphasis on studies in the domain of professional capability development (92.29%), and there are few studies in the domain of enabling environment for learning (0.72%); the domain of expertise (3.01%) and strategic vision of BI&A was also rare (3.37%).

Given the neurotrauma that soldiers might face during wars, a byproduct of such devastating neurosurgical conditions can be novel data, which can act as a catalyst for potentially paradigm-shifting research. We aimed to identify the impact of major U.S. military campaigns on military neurosurgery literature across defined time periods. A comprehensive Elsevier's Scopus database search was performed to capture all published and indexed studies from 1915 to 2021 relevant to military neurosurgery. A discrete set of validated informetric metadata parameters were extracted and analyzed using productivity analysis, citation analysis, keyword analysis, text mining, content analysis, and collaboration network mapping. Our search yielded 2216 documents. Annual scientific production since 1915 grew at a compounded rate of 6.1% per year, with the most significant increases during U.S. military campaigns (coefficient = 42.9, P < 0.001) and following the introduction of the Department of Defense Trauma Registry in 2007 (coefficient = 114.5; P < 0.001). Each war had a direct influence on military neurosurgery literature growth (P < 0.05), with the most prominent following the Afghanistan war. The journals with the most publications on military neurosurgery were Military Medicine (n = 168) and Journal of Head Trauma. The topmost cited author was Hoge et al. (N = 2083), while the topmost cited country was the United States (N = 1098). Since World War II, the military has contributed significant historical developments to neurosurgery, the most prominent being after the Iraq and Afghanistan wars and the introduction of the Department of Defense Trauma Registry.

The literature on neurofibromatosis (NF) has never been systematically assessed using bibliometric analytic methodologies. We quantitatively analyzed the major trends and scientific output regarding NF, highlighting potential avenues for research. An Elsevier's Scopus database search was performed for all indexed studies related to NF from 1898 to 2021. Validated bibliometric parameters were analyzed using productivity, citation, and keyword analysis, including text mining, content analysis, and collaboration network mapping from inception to date on R 4.1.2. Our search yielded 15,024 documents. Annual scientific production has grown at a compounded rate of 5.86%, with the largest occurring in 2021 (n = 626). Journals with the most publications on NF include the Journal of Medical Genetics (n = 117) and Neurology (n = 113). The topmost cited author was Gutmann DH (n = 295). The United States had the most international collaboration (n = 435; multiple country publications). Identification of citation classics revealed a shift in recent decades towards understanding genetic and molecular pathways of NF tumorigenesis. Macro-level and micro-level text mining revealed the top 20 genetic and molecular pathways, and syndromes, associated with NF. Our study exemplifies a quantitative method for understanding the historical and current state of academic efforts regarding NF. There has been a shift of treatment strategies towards targeting specific pathways involved in tumorigenesis. We highlight the top 20 genetic and molecular pathways in the literature as well as the top 20 associated syndromes. This data is encouraging as increased research in molecular targeted therapies aimed at NF pathogenesis may allow advances in disease control. [ABSTRACT FROM AUTHOR]

Fault tree analysis (FTA) is one of the important analysis methods of safety system engineering commonly utilized in various industries to evaluate and improve the reliability and safety of complex systems. To grasp the current situation and development trend of FTA research and to further point out FTA's future development directions, 1469 FTA-related articles from the literature were retrieved from the SCIE and SSCI databases. Informetric methods, including co-authorship analysis, co-citation analysis and co-occurrence analysis, were adopted for analyzing the cooperation relationship, research knowledge base, research hotspots and frontier in the FTA research field. The results show that China has the highest number of publications, and the Loughborough University of England has the highest number of publications of relevant institutions. Dynamic fault tree analysis, fuzzy fault tree analysis and FTA based on binary decision diagrams are recognized as the knowledge bases in FTA studies. "Reliability Engineering and System Safety", "Safety Science" and "Fuzzy Sets and Systems" are the core journals in this field. Fuzzy fault tree analysis, dynamic fault tree analysis based on Bayesian networks and FTA combined with management factors may be both the main research hotspots and the frontiers. Then, by deriving the above results, this study can help scholars better master the current research status and frontiers of FTA to improve system reliability and safety. [ABSTRACT FROM AUTHOR]

This study was conducted to determine the relationship between open access presence and ranking of African universities. It adopted descriptive informetric to examine open access presence of African countries using Directory of Open Access Repositories (DOAR) and Research Gate scores (RGs) of the universities. Data was also extracted from the Journal Consortium (an African university ranking organisation) for metrics on African university ranking. Data on African open access presence was correlated with university rankings. Findings reveal that only twenty-four countries in Africa have records in DOAR and Research gate. Four of the countries (South Africa, Egypt, Kenya and Nigeria) contribute more over 85% of open access records in Africa and the same produced 68% of the top 100 universities in Africa. The study found a highly significant positive but moderate correlation between open access presence and ranking of African universities. It concludes that African universities need to review their science policy in line with open access initiative to enhance the visibility and ranking of the university globally.

Neurodegenerative diseases, namely Alzheimer's (AD), Parkinson's (PD), and Huntington's disease (HD) together with amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS), devastate millions of lives per year worldwide and impose an increasing socio-economic burden across nations. Consequently, these diseases occupy a considerable portion of biomedical research aiming to understand mechanisms of neurodegeneration and to develop efficient treatments. A potential culprit is cholesterol serving as an essential component of cellular membranes, as a cofactor of signaling pathways, and as a precursor for oxysterols and hormones. This article uncovers the workforce studying research on neurodegeneration and cholesterol using the TeamTree analysis. This new bibliometric approach reveals the history and dynamics of the teams and exposes key players based on citation-independent metrics. The team-centered view reveals the players on an important field of biomedical research. [ABSTRACT FROM AUTHOR]

From an informetrics perspective, we discuss the relationship between the Least Effort Principle and information cost minimisation, and discuss the implications for Zipf's law. We propose a mathematical proof of a theorem demonstrating that if one minimises the average cost per unit of information, the Least Effort Principle (LEP) will be verified regardless of the effort function chosen. We then show that Zipf's law can be demonstrated on the basis of the two models studied, namely Average Cost per Unit of Information and the Least Effort Principle (LEP). • Math proof shows minimizing info cost per unit satisfies Least Effort Principle (LEP) for any effort function chosen. • In the continuous mode, the equivalence of the two principles is shown using a class of 'admissible' effort functions. • This article establishes the relationship between the PLE and the average cost per unit of information. • If we minimise the average cost per unit of information, PLE is proved independently of the chosen effort function.

Noma is an orofacial gangrenous infection commonly affecting malnourished children in the tropical region of the World, particularly the sub-Saharan Africa. Nigeria is a sub-Saharan African country which is among the countries seriously affected by noma. In Nigeria, noma has been classified as a priority disease. However, only very little attention has been focused on noma research in Nigeria, unlike many other priority diseases. This study conducted an informetric analysis of research outputs on noma in Nigeria, using the PubMed database - a world-leading and authoritative database of medical literature. This study revealed that only 26 PubMed-indexed publications on noma (PONs), published between January 1990 and September 2021, were available. A trend analysis of these PONs showed that the average output (outputs from 1999 to 2020 = 23) rate per year (from 1990 to 2020 [31 years]) was 0.74 (23/31). Sokoto ( n = 11), Oyo ( n = 4) and Kebbi ( n = 3) were the top three Nigerian states surveyed on noma in the included PONs. Only 12 publications had international co-authors, of which only few publications had co-authors affiliated with institutions in other African countries: South Africa - 5 publications; and Rwanda - 2 publications. Only two publications were funded. Also, the top five prolific Nigerian authors on noma in Nigeria were affiliated with Noma Children Hospital, Sokoto State, Nigeria. In conclusion, PONs by Nigerian authors is so meagre in quantity. This low output is an issue of medical concern. More research focused on noma in Nigeria is needed through funding and other research capacity-strengthening measures., Competing Interests: The author declare that they have no competing interests.
