The objective of this article is to identify the trends of the publications in the Congresses USP, ANPCONT and CBC that address the costing methods, between the period of 2015 to 2017. The methodology is qualitative with the use of the bibliometric technique, the data collected through the websites being analyzed a universe of 779 articles, categorized in: quantity of published articles on accounting of Costs; number of published articles on costing methods; typology of the costing methods used in each article; applied in the articles on costing methods. The results showed that CBC, 8% of the works submitted in 2015 referred to the Costing Methods, in 2016 this percentage was 12%, and in 2017, 15%. At the USP Congress, only two studies discussed costing methods, while in 2016 and 2017 articles were not identified that address costing methods. At the ANPCONT Congress, 118 articles were presented in the year 2015, of which 12 were related to the subject of Cost Accounting, none of which deals effectively with the Costing Methods. It is concluded that CBC was the congress presented the largest number of articles related to this issue of costing methods, when compared to the Congresses USP and ANPCONT.

Ecuador, a country of 17 million inhabitants with a medium hwnan development index of 0.75, has a small scientific productivity in relation to its size and population. Objective: To analyze Ecuador publications in the Science Citation Index Expanded, focusing on productivity, subjects, institutions, citations, and trends. Methods: We analyzed scientific publications by authors from Ecuador from 1900 to 2017 in the Science Citation Index Expanded and compared it with other tropical countries. Results: We found 16 document types (7 806 articles). The three most productive institutions were Universidad San Francisco de Quito. Pontificia Universidad Catolica del Ecuador, and Escuela Politecnica Nacional. USA and Spain were the most frequent collaborating countries. Most articles were in English and ecology, botany, and zoology were common, but no field produced over 8 % of articles. However, ecology represents 11.3 % of the total citations. The most cited papers in the database were from large international biology and physics projects with minimal participation of Ecuadorean scientists. Article citations occurs mostly after the SCI stops counting. Conclusion: Science in Ecuador is growing but needs to greatly increase collaboration among Ecuadorean institutions to reduce its dependence on forcing projects. However, this study did not include articles published by the hundreds of Ecuadorean journals not covered by the SCI Expanded

In the realm of multi-criteria decision-making (MCDM) problems, the selection of a weighting method holds a critical role. Researchers from diverse fields have consistently employed MCDM techniques, utilizing both traditional and novel methods to enhance the discipline. Acknowledging the significance of staying abreast of such methodological developments, this study endeavors to contribute to the field through a comprehensive review of several novel weighting-based methods: CILOS, IDOCRIW, FUCOM, LBWA, SAPEVO-M, and MEREC. Each method is scrutinized in terms of its characteristics and steps while also drawing upon publications extracted from the Web of Science (WoS) and Scopus databases. Through bibliometric and content analyses, this study delves into the trend, research components (sources, authors, countries, and affiliations), application areas, fuzzy implementations, hybrid studies (use of other weighting and/or ranking methods), and application tools for these methods. The findings of this review offer an insightful portrayal of the applications of each novel weighting method, thereby contributing valuable knowledge for researchers and practitioners within the field of MCDM.

Optical and thermal remote sensing data have been an important tool in geological exploration for certain deposit types. However, the present economic and technological advances demand the adaptation of the remote sensing data and image processing techniques to the exploration of other raw materials like lithium (Li). A bibliometric analysis, using a systematic review approach, was made to understand the recent interest in the application of remote sensing methods in Li exploration. A review of the application studies and developments in this field was also made. Throughout the paper, the addressed topics include: (i) achievements made in Li exploration using remote sensing methods; (ii) the main weaknesses of the approaches; (iii) how to overcome these difficulties; and (iv) the expected research perspectives. We expect that the number of studies concerning this topic will increase in the near future and that remote sensing will become an integrated and fundamental tool in Li exploration.
