Different approaches of bibliometric analysis for data analytics applications in non-profit organisations (FULL-TEXT)

Profitable companies that used data analytics have a double gain in cost reduction, demand prediction, and decision-making. However, using data analysis in non-profit organisations (NPOs) can help understand and identify more patterns of donors, volunteers, and anticipated future cash, gifts, and grants. This article presents a bibliometric study of 2673 to discover the use of data analytics in different NPOs and understand its contribution. We characterise the associations between data analysis techniques and NPOs using, Bibliometrics R tool, a co-term analysis and scientific evolutionary pathways analysis, as well as identify the research topic changes in this field throughout time. The findings revealed three key conclusions may be drawn from the findings: (1) In the sphere of NPOs, robust and conventional statistical methods-based data analysis procedures are dominantly common at all times; (2) Healthcare and public affairs are two crucial sectors that involve data analytics to support decision-making and problem-solving; (3) Artificial Intelligence (AI) based data analytics is a recently emerging trending, especially in the healthcare-related sector; however, it is still at an immature stage, and more efforts are needed to nourish its development. The research findings can leverage future research and add value to the existing literature on the subject of data analytics.

Worldwide research trends on the use of chemical–mechanical caries removal products over the years: a critical review (Full-Text)

Chemical–mechanical caries removal (CMCR) products are in constant evolution and were recommended during the COVID-19 pandemic as substitutes for conventional caries removal. The aim of this paper is to characterize the worldwide scientific literature about CMCR products, over the years, by means of a critical review. An electronic search was performed on Medline/PubMed, Scopus, Web of Science, Cochrane Library, Lilacs, and Embase up to November 2020. Year, journal, country of authors, and type of study were the data extracted from the retrieved studies. Additional data of the clinical studies and systematic reviews were investigated. For results, 2221 records were identified, 397 selected. 2011–2020 period concentrates higher number of publications (n = 169), in the Journal of Dental Research (n = 51), developed in Brazil (n = 45) and India (n = 44). Most studies were in vitro (n = 211) and clinical trials (n = 101). Carisolv™ (n = 48) and Papacarie Duo Gel™ (n = 33) were the most used products, prescript in isolated usage (n = 101), and compared with drills (n = 77). CMCR were more studied in primary teeth (n = 78), receiving glass ionomer cement (GIC) (n = 51) as restorative material. The most evaluated outcomes were time spent (n = 48) and pain (n = 41). Clinical application of CMCR takes more time than other techniques, but can also reduce patient anxiety, pain, and need for anesthesia. Our conclusion is nn vitro and clinical studies with CMCR products have been increasing, mostly carried out in developing countries, evaluating Carisolv™ and Papacarie Duo Gel™. Clinical studies tend to evaluate the time spent and pain compared to drills for removing caries in primary teeth, posteriorly restored with GIC. CMCR clinical application reduces anxiety, pain, and need for anesthesia, despite increase treatments’ time.

Identification of factors affecting the reduction of VOC emissions in the paint industry: Systematic literature review – SLR (Full-Text)

In recent years, the interest of the manufacturing industry in new perspectives aimed at sustainability has increased, driving the manufacture of paints to use alternatives that help to reduce the impacts generated by the emission of Volatile Organic Compounds (VOCs); these impacts are especially negative since they have environmental consequences related to atmospheric pollution and social consequences due to their harmful effects on human health. The economic field has a positive effect due to the performance and varied application of the coatings in different industries. A systematic literature review (SLR) was conducted to identify factors that contribute to the reduction of VOCs emissions in the coating industry. Search equations were proposed with selected keywords, reading and selection of articles, analysis and classification of the information and finally plotting the data with the use of VantagePoint software. A total of 51 articles were selected for analysis, finding three key factors. (1) green chemistry, based on the formulation of paints from the use and/or synthesis of raw materials with renewable materials; (2) incorporation of cleaner production strategies which involves the change of paint technology, such as water-based, powdered, or with variation of the solids content; and (3) regulations and standards that must be complied with regarding VOCs emissions and that depend on the type of industries and the country where they are applied. Polyurethane resins were identified as the most studied for VOCs abatement. The paints market has focused on new sources to develop environmentally friendly materials, introducing manufacturing processes and technologies that combine sustainability and performance in this industry.

The scientific publication of the Memórias do Instituto Oswaldo Cruz (1909-2020): a history of contribution to the biomedical sciences (Full-Text)

The Memórias do Instituto Oswaldo Cruz (MIOC) is one of the first scientific journals created in Brazil and
currently one of the most important biomedical journals in South America. Knowledge of the main themes disseminated over time and its main contributors can contribute towards a better understanding of its trajectory and future. The objective of this paper was to map the journal’s scientific publication between 1909 and 2020. Data from three scientific databases was combined, alongside bibliometrics and network analysis to analyse publication records between 1909 and 2020. Publications increased substantially since the 1980s. The main publishing organisations are Brazilian. Excluding Brazil, the main publishing countries are the USA, Argentina, and Colombia. During the entire investigated period, the main themes refer to Chagas disease, schistosomiasis, and Leishmaniasis. During some periods, publications followed disease outbreaks in Brazil (e.g., dengue fever and yellow fever). Since its foundation in 1909, the MIOC has focused on infectious and parasitic diseases. The editorial changes implemented from the 1980s onwards led MIOC to a relevant growth concerning annual publications and its transformation into an important communication vehicle for researchers from several Brazilian organisations besides Fiocruz, as well as organisations from other countries, especially within Latin America.

Research Trends on Pillared Interlayered Clays (PILCs) Used as Catalysts in Environmental and Chemical Processes: Bibliometric Analysis

Over the last four decades, a large number of studies have been published on pillared interlayered clays (PILCs) used as adsorbent materials and catalysts or supports for transition metals in heterogeneous catalysis. Particularly, PILCs have been used for water treatment through advanced oxidation processes (AOPs) to remove organic pollutants. They have also been studied in various chemical and environmental processes. Because of the growing interest in PILCs, this article is focused on analyzing scientific publications such as research/review articles and book chapters from the last four decades (from 1980 to 2019) through a bibliometric analysis (BA) to visualize and describe research trends on PILCs. By narrowing the bibliographic search to titles, keywords, and abstracts of publications related to PILCs, using Scopus and Web of Science (WoS) (the two scientific databases), a total of 3425 documents have been retrieved. The bibliometric dataset was analyzed by VantagePoint®. The main research trends identified in the last four decades were the use of PILCs in environmental processes (34.4% of total publications) along with chemical processes (petrochemical reactions 17.5%, SCR NOx 10.8%, and decomposition 8.2%). In environmental processes, PILCs have been used in photo-oxidation (32%), CWPO (21.1%), and heterogeneous catalysis (19.4%). Phenols, dyes, and VOCs have been the main pollutants studied using PILCs as catalysts. Fe, Ti, Zr, Cu, and Co are the most supported active phases in PILCs. Other research trends grouped by characterization techniques, countries, research areas, institutes, scientific journals that have published the most on this topic, number of publications per 5-year period, and most frequently used keywords through the last four decades have been identified. It was determined that the number of publications on PILCs has increased since 1980 and the countries with the highest number of publications are China, Spain, and The United States of America.
