Background: Biosimilars could be a promising option to help decrease healthcare costs and expand access to treatment. There is no previous evidence of a global bibliometric analysis on biosimilars. Therefore, we aimed to assess the quantity and quality of worldwide biosimilars research. Methods: We performed a bibliometric analysis using documents about biosimilars published until December 2016 in journals indexed in Scopus. We extracted the annual research, languages, countries, journals, authors, institutions, citation frequency, and the metrics of journals. The data were quantitatively and qualitatively analyzed using Microsoft Excel 2013. Additional information about authors’ participation was obtained using the R-package Bibliometrix. Publication activity was adjusted for the countries by population size. Also, author co-citation analysis and a term co-occurrence analysis with the terms included in the title and abstract of publications was presented as network visualization maps using VOSviewer. Results: A total of 2330 biosimilar-related documents identified in the Scopus database, most of them were articles (1452; 62.32%). The number of documents published had an exponential increased between 2004 and 2016 (p <0.001). The United States was the country with the highest production with 685 (29.40%) documents followed by Germany and UK with 293 (12.58%) and 248 (10.64%), respectively. Switzerland (11.05), Netherlands (5.85) and UK (3.83) showed the highest per capita ratio. The highest citation/article ratio were for the Netherlands (28.06), Spain (24.23), and France (20.11). Gabi Journal published 73 (3.13%) documents; both Biopharm International and Pharmaceutical Technology and Mabs, 41 (1.76%). Three out of top ten journals were Trade publications. Amgen Incorporated from the USA was the most prolific institution with 51 documents followed by Pfizer Inc. with 48. Terms about specific diseases and drugs were found in recent years, compared with terms such as legislation, structure, protein, dose and generic in the early years. Conclusions: Research production and publication of documents on biosimilars are increasing. The majority of publications came from high-income countries. The trends in terminology use are according to state of the art in the topic, and reflects the interest in the utilization of biosimilars in diseases who are expected to obtain benefits of its use.

 

 

Introduction: This article is a product of the research on “The bibliometric analysis of Central America and Caribbean journals” that takes place at the Technological University of Panama in 2018. Objective: to measure the impact of open access journals and compare the countries of the study region. Also study the position of the magazines in Panama with respect to the other countries of the region. Methodology: We used the data from the indexed journals in DOAJ extracted in CSV format that were filtered by countries in a total of 211 journals and compared with indexers Latindex, Redalyc, Scielo and Redib in a total of 42 journals which were analyzed bibliometrically a Through the publish or perish software. Results: Most of the journals of the study region that belong to DOAJ comply with the necessary guidelines to index in the regional directories, however, of the 211 journals analyzed, only 42 have been integrated to the 4 indexers. Conclusions: The visibility of journals in the study region has improved the visibility of their publications, however, compared to countries such as Brazil, Indonesia and the United Kingdom, it is lower in impact numbers. Originality: In Panama there are no studies to measure scientific production or the impact of journals. Limitations: No data on this topic has been found in engineering publications.

 

 

This article has the following question as a problem: what do researches that tackle Special Education in/from the Countryside say about school curriculum for subjects with disability, autism spectrum disorders and high skills/giftedness? Thus, it aims to: analyze scientific production deriving from theses and dissertations produced in Brazil about the topic of Special Education in/from the Countryside, as well as if they tackle and how they tackle school curriculum for these subjects. The study was carried out by means of the adoption of bibliometric approach and content analysis, which took as a data source the Brazilian Digital Library of Theses and Dissertations (Biblioteca Digital Brasileira de Teses e Dissertacoes – BDTD), which is maintained by the Brazilian Institute of Information in Science and Technology (Instituto Brasileiro de Informacao em Ciencia e Tecnologia – IBICT). Results reveal 31 works on the theme of Special Education in/from the Countryside over the last 25 years. Out of these, only five works tackle school curriculum in/from the countryside for the target audience of Special Education, albeit not directly, but as a theme that emerges from the main theme tackled by their authors. Therefore, investigating about the development of school curriculum for the audience of Special Education in/from the countryside is a challenging task.

 

 

Value chains are an important driver for the current labor dynamics in the agri-food sector, and agri-food value chain sustainability strongly depends on decent work conditions. An increasing literature body have been investigated the interactions between chain agents and how it impacted labor issues. Our aim was to map the scientific landscape of the scientific knowledge on labor in agri-food value chains. We performed a bibliometric review of 343 articles indexed in the Web of Science based on descriptive and network analysis of articles metadata, which covered authors, journals, citation times, keywords and countries. We showed that labor in agri-food value chains has an international audience, despite that knowledge production was largely built by a restraint leading scientific network. Overall, the scientific knowledge is organized into four main research domains on labor in agri-food value chains: (1) labor governance in global value chains through standards, (2) employment in value chains and impacts on socioeconomic conditions of rural areas, (3) gender issues and value chains, (4) labor and upgrading in global value chains. The controversies in the international literature regarding labor issues in the agri-food value chains, and blind spots of current research are discussed.

 

 

The purpose of this study was to investigate the association between language and total number of citations found among documents in journals written in English and other languages. We selected all the journals clustered together in the Journal Citation Reports 2014 under the subject category “Veterinary Sciences” and downloaded all the data registered between 19942013 by Web of Science for the journals that stated publishing documents in languages other than English. We classified each of these journals by quartile and extracted information regarding their impact factor, language(s) stated, country of origin, total number of documents published, total number of reviews published, percentage of documents published in English and the quartile in which each journal ranked. Of the 48,118 documents published by the 28 journals analyzed, 55.8% were published in English. Interestingly, although most of the journals state being multi-language, most documents published in quartile 1 journals were in English (an average of 99.2%), while the percentage was 93.1% in quartile 2 journals, 62.1% in quartile 3 journals and 27.4% in quartile 4 journals. We also confirmed that citation distribution in these journals was highly skewed. The results of this study suggest that journals should consider adopting English as the main language as this will increase citation counts and the impact factor of the journal.

 

 

The conceptual variations and divergences that permeate the debate on sustainability end up directly reflecting the choice of sustainability assessment (SA) processes, providing different methodological approaches. Among them, some researchers have pointed out challenges, but also opportunities to use geospatial data, techniques, and tools as resources to be explored in sustainability assessments. However, it was still unclear how geospatial tools have contributed in this context, as well as their future potential. Thus, through bibliometric mapping, this research answers these questions, through the identification of both the thematic fields of action of the geographic information system (GIS) in SA as well as the emerging research areas in this domain of knowledge. For this, we selected 1721 articles spanning 31 years (1990-2020). We observe that this is a subject of growing interest, as more than 50% of all publications were published after 2015. The main results indicated that, initially, the GIS supported sustainability assessments as a mapping tool associated mostly with environmental issues, however, the evolution of the analysis potential, through data modeling, gives rise to new application perspectives. This evolution takes place, in parallel, with the global discussion on sustainability, where multidimensionality starts to play a leading role, and sustainability indicators assume geographic positions.

 

 

This article aims to present research conducted on the literature regarding multi-objective optimization for routing problems with environmental considerations, referred to here as Multi-objective Optimization for the Green Vehicle Routing Problem (MOOGVRP). A Brazilian database, CAPES (Coordination for the Improvement of Higher Education Personnel), was used to collect articles of general application, case studies and reviews in English starting from, since 2012. The terms “green vehicle routing problem” (GVRP), “pollution routing problem” (PRP), “vehicle routing problem in reverse logistics” (VRPRL) and “multi-objective” were used in the research protocol. Consequently, this study obtained 1,744 research results that, following the application of the filtering criterion, resulted in a sample of 76 articles from 38 journals, for which a bibliometric data (bibliometric review) survey was conducted. The originality of this article lies in how the research is presented, highlighting the results and details obtained through the survey, which may be considered of great academic importance in the sense of guiding the trends for future research.

 

 

This article analyses how the concept of sustainability is being incorporated into global research of higher education. This study utilizes different scientometric reviews of global research between 1991 and 2018 using text mining techniques in order to generate first and second-generation bibliometric indicators, the latter are displayed in science maps. A total of 6724 articles and conference proceedings were collected from the Web of Science and Scopus databases to generate this research. From the results obtained, it was possible to build a canvas of the main institutions that have significantly contributed to the topic of sustainability in higher education, and it was found that 40.58% of the records originated in institutions from the United States, China, United Kingdom, and Australia. This study also provides an insight into emerging trend themes, and patterns of research in the area of sustainability worldwide. Terms such as regional planning and environmental protection inside the top keywords found, suggest a greater interest in issues of sustainable planning and social awareness and that higher education is becoming the cornerstone of environmental awareness, innovation, and guidance to achieve sustainability goals in higher education institutions, as well as in society and government.

 

 

This study aims to provide a systematic analysis of the literature of methods and resources supporting geoconservation and geotourism worldwide, while identifying current and future trends in the field. This paper offers a comprehensive bibliometric analysis which comprises the period of 2011-2021 after an in-depth systematic literature review of 169 papers, using Web of Science. The volume of research on these topics is growing rapidly, especially in Italy, Poland, Brazil, Russia, and China; these constitute the most productive countries. The main identified geomorphological environments are sedimentary, volcanic, aeolian, coastal, fluvial, and karstic. We discovered that the main methods for evaluating geoconservation and geotourism are geomorphological mapping, the study of economic values for geotourism, field work as a research tool, geoheritage management, documentation, exploration, and inventories of geoheritage at a regional level. The main determined resources are UNESCO Geoparks, educational activities, digital tools, geomanagement, economic values, geoitineraries, and geoeducation programs. To our knowledge, this is the first study dealing with methods and resources publicizing geoconservation and geotourism, worldwide. Knowing about the most successful methods and resources for promoting geoconservation and geotourism can definitely be useful for future endeavors in countries where geoheritage studies are starting to be developed.

 

 

The detection of analytes in complex organic matrices requires a series of analytical steps to obtain a reliable analysis. Sample preparation can be the most time-consuming, prolonged, and error-prone step, reducing the reliability of the investigation. This review aims to discuss the advantages and limitations of extracting bioactive compounds, sample preparation techniques, automation, and coupling with on-line detection. This review also evaluates all publications on this topic through a longitudinal bibliometric analysis, applying statistical and mathematical methods to analyze the trends, perspectives, and hot topics of this research area. Furthermore, state-of-the-art green extraction techniques for complex samples from vegetable matrices coupled with analysis systems are presented. Among the extraction techniques for liquid samples, solid-phase extraction was the most common for combined systems in the scientific literature. In contrast, for on-line extraction systems applied for solid samples, supercritical fluid extraction, ultrasound-assisted extraction, microwave-assisted extraction, and pressurized liquid extraction were the most frequent green extraction techniques.
