RESUMEN

Many papers offer methods for preparing a systematic literature review. These methods assume that the researchers have some experience in research, are proficient in English, and that the research objective is solely a literature review. This article presents a systematic method for preparing a literature review aimed at novice researchers who have four to twelve weeks to develop their work and do not have the guidance of a professor. Originality is associated with the objective of the literature review. The proposed method aims to elaborate the literature section of a technical article, while the other methods aim to elaborate a literature review article. The method's flexible structure allows for increasing the depth of the results according to the researcher's capacity. Another innovation of the presented method consists of a structure that allows the simultaneous consideration of international and national literature.•This paper introduces a systematized method to guide novice researchers in preparing the literature review section of their research.•The method has an easy-to-follow structure that does not require the novice researcher to follow up with a professor.•The method allows adjusting the depth level of the international literature review through the number of articles subject to content analysis, exploring the international and national literature through a set of materials (graphs, forms, and figures) that facilitate and speed up the elaboration, synthesis, and presentation of the results.

RESUMEN

Landslides are generated by natural causes and by human action, causing various geomorphological changes as well as physical and socioeconomic loss of the environment and human life. The study, characterization and implementation of techniques are essential to reduce land vulnerability, different socioeconomic sector susceptibility and actions to guarantee better slope stability with a significant positive impact on society. The aim of this work is the bibliometric analysis of the different types of landslides that the United States Geological Survey (USGS) emphasizes, through the SCOPUS database and the VOSviewer software version 1.6.17, for the analysis of their structure, scientific production, and the close relationship with several scientific fields and its trends. The methodology focuses on: (i) search criteria; (ii) data extraction and cleaning; (iii) generation of graphs and bibliometric mapping; and (iv) analysis of results and possible trends. The study and analysis of landslides are in a period of exponential growth, focusing mainly on techniques and solutions for the stabilization, prevention, and categorization of the most susceptible hillslope sectors. Therefore, this research field has the full collaboration of various authors and places a significant focus on the conceptual evolution of the landslide science.

RESUMEN

RESUMEN El objetivo de este artículo fue realizar un estudio bibliométrico de las publicaciones de la RPMESP (2010-2019) con el fin de posibilitar el mejoramiento de los procesos de gestión editorial y toma de decisiones de esta y otras revistas científicas con similar comportamiento. Es un estudio descriptivo con metodología bibliométrica que analiza por medio de indicadores de productividad, colaboración y de redes las principales tendencias de la revista. Los registros fueron recuperados de Scopu, del cual, luego de un proceso de normalización, se obtuvieron 565 documentos. El 96% de documentos se publicaron en idioma español y en colaboración (dos o más autores), esto refleja que hay mayor interés de autores latinoamericanos de publicar en colaboración en los últimos años. Se observó un incipiente grado de apertura internacional al recibir documentos de países como Estados Unidos, Colombia y España, tendencia que es necesario continuar trabajando en la búsqueda de un mayor grado de internacionalidad. Perú como país y la Universidad Peruana Cayetano Heredia como institución tuvieron las mayores medidas de centralidad y poder en el análisis de redes. La posición estratégica de estos nodos puede ser aprovechada por la RPMESP para establecer estrategias y fortalecer relaciones de colaboración con todos los miembros de estas redes. Este paso podría mejorar el rol importante que cumple la RPMESP en la divulgación científica de estudios médicos en respuesta a las grandes demandas actuales.

ABSTRACT The objective of this article was to carry out a bibliometric study of the RPMESP publications (2010-2019) in order to enable the improvement of the editorial management and decision-making processes of this and other journals with similar behavior. It is a descriptive study with bibliometric methodology that analyzes through productivity, collaboration and network indicators the main trends of the journal. The records were recovered from Scopus, which, after a standardization process, obtained 565 documents. 96% of the documents were published in Spanish and in collaboration (two or more authors), which reflects the greater interest of Latin American authors in publishing in collaboration in recent years. An incipient degree of international openness was observed when documents were received from countries such as the United States, Colombia, and Spain, a trend that needs to be continued in the search for a greater degree of internationality. Peru as a country and the Universidad Peruana Cayetano Heredia as an institution had the greatest measures of centrality and power in network analysis. The strategic position of these nodes can be used by the RPMESP to establish strategies and strengthen collaborative relationships with all members of these networks. This step could improve the important role that the RPMESP plays in the scientific dissemination of medical studies in response to the great demands of today.

RESUMEN

Because the Amazon rain forest is ecologically relevant on a global scale, we applied scientometric techniques to integrate studies dealing with mercury research in this unique ecosystem between 1991 and 2017. Using a combination of co-authorship and co-citation analyses, keyword mapping and overlay visualization of topics in the field, this article identified three major areas in the 26-year period of mercury research: (1) human exposure to mercury (artisanal small-scale gold mining-ASGM) and methylmercury through fish consumption, and their respective risks for human health; (2) mercury accumulation in the environment and its relation to ASGM and atmospheric concentration; and (3) mercury geochemistry and its presence in soils, sediments, and water. The paper also identified the leading institutions related to the published research and respective influential scholars in the context of this study. Overall, the analyses revealed patterns of convergence and divergence between authors, specialization, and interdisciplinary engagement in mercury investigation, thus highlighting strengths and weaknesses of research topics in the field. This scientometric approach could be a useful tool to monitor/assess the implementation of the Minamata Convention.
