While there is a progressive ageing of the population, we are witnessing a rapid development of new information and communication technologies (ICTs). Although for most of society this technology is within reach, there are population segments for whom access is limited, especially adults who are considered of old age. Due to the relevance that the relationship between ICTs and older adults acquires in today's society, it is necessary to carry out an analysis of the scientific literature in order to understand the knowledge structure of this field. In this research, a comparative bibliometric analysis of 172 documents published in the Web of Science (WoS) and Scopus databases was carried out until 2018 and is complemented by a co-citation analysis. The results show that this subject is incipient and is in its exponential growth stage, with two thirds of the production concentrated in the 2012-2018 period. Four out of five authors are transient with a single authorship and the collaboration level is high. The most productive country is Germany followed by the United States and Australia.

Digital transformation and technological advances are causing a radical change in communication structures and in the way information is consumed. With rapid development of computing and the Internet, data is generated, recorded, stored and accumulated on a large scale, making it necessary for economic sectors to act quickly in order to adapt their businesses to the online environment and thus, ensure their own survival. The application of Big Data in tourism enables to transform all this data into useful information, so that companies in the sector can define and optimize their strategies in order to increase their profits. This article performs a comparative bibliometric analysis of the presence and impact of scientific production related to Big Data within the area of tourism research indexed in the WoS and Scopus databases. The aim is to know key aspects such as its growth, correlation, citation, coverage, overlap, dispersion or concentration that will support future researchers when they start their work in this emerging field. From the analysis of the 113 articles selected between the two bases through an advanced search for terms with a time limit set in 2019, it can be concluded that this is a new field of knowledge, which has aroused great interest since 2017, publishing about two thirds of the articles during the period 2017–2019. Although WoS and Scopus differ in general terms in scope and coverage policies, both systems are complementary and not exclusive. In the specific area of Big Data and Tourism Research, Scopus is the base that provides better coverage by collecting a higher number of articles and receiving more citations. [ABSTRACT FROM AUTHOR]

Beer is popular worldwide and it is considered the oldest and most consumed alcoholic beverage in the world. At the global production level, most of the market is dominated by a few multinational companies, but in recent years, craft beers have gained market share. In addition to being independent and produced on a smaller scale, the main characteristic of craft breweries is their broad differentiation capacity, attracting consumers who demand products that are more committed to sustainability and the environment, as well as being willing to pay higher prices for goods in line with their life philosophy. Their great popularity aroused the interest of researchers throughout the world, leading to the proliferation of a large number of scientific articles that address the production and consumption of craft beer. This research aims to identify and analyze the scientific production that addresses Craft Beer. A bibliometric analysis is used as the methodology to obtain the following information regarding the subject over the years: growth and coverage, article citations (quality indicator), the most relevant authors, etc., which will be useful information for researchers. The two main international databases, WoS and Scopus are used for document tracking and 137 articles are identified. The results show that this is a recent area of study, since researchers only started showing interest in the subject in 2015; 90% of the documents have been published in the last 5 years. Most of the authors are transient with a single authorship, so the production is low (productivity index 1.18). Therefore, the study area is incipient and is considered of great potential for researchers. [ABSTRACT FROM AUTHOR]

Purpose Since Masaaki Imai coined the term Kaizen in the mid-1980s, it has been seen as a key element for the competitiveness of Japanese companies, and it is currently a widely discussed philosophy and is applied in a wide range of organizations throughout the world. The purpose of this paper is to serve as guidance for researchers who are developing their studies in the field of the Kaizen philosophy, in order to improve their knowledge on the most relevant articles, the most productive authors or the key scientific journals that make up this subject.Design/methodology/approach In order to fulfill the proposed objective, a descriptive bibliometric study was carried out with the analysis of citations from 138 articles included in the multidisciplinary database Scopus (Elsevier) until 2016. For the search of documents, a tracking strategy was chosen that allowed for the development of the ad hoc database required to analyze each of the basic variables of the bibliometric indicators.Findings The results obtained show a growing interest of the scientific community in its study in the last decade, as shown by the significant increase in citations received by articles, despite the reduction in the number of papers published in the last two years.Research limitations/implications The main limitations are derived from the choice of a specific database, as well as the specific search equation.Originality/value The study presents an in-depth analysis of the current state of research regarding the Kaizen philosophy through its bibliometric study, providing useful information for academics and professionals by providing a series of significant indicators to measure the bibliographic material.

Two of the greatest challenges that threaten sustainable development are the water supply crisis together with the control of water resources pollution. The United Nations recognises that the right to safe drinking water and sanitation is an essential right, and states are called upon to intensify their efforts to provide the entire population with affordable access to safe drinking water. However, due to population growth and climate change, water resources are under great pressure, producing millions of cubic metres of wastewater. Due to the near impossibility of increasing water supply in a natural way, the importance of wastewater management as a method has grown in recent years, which, although it is not to increase the amount of this resource, but to facilitate its successive use before its final return to the sea. The objective of this article is to carry out a bibliometric analysis regarding the production and impact of the scientific research related to wastewater management indexed in the WoS and Scopus databases. The purpose is to know key aspects such as the progression of production over the years, maturity in research, coverage of the subject, identifying the most discussed topics and therefore identifying the gaps, the most relevant authors and the core of journals through which knowledge in this area is disseminated, as well as its impact through the analysis of citations. This analysis can help future researchers in this field by providing an overview of the current literature that helps them identify new research approaches to position their own work and identify the most relevant authors in this field. Likewise, a comparison is made on coverage and overlap between the two main international databases WoS and Scopus. From the analysis of the 211 articles selected through an advanced search by terms with a time limit set in 2018, it is concluded that we are facing a very incipient field of knowledge that has aroused great interest since 2010, with about half of the articles published in the period 2012–2018. Although WoS and Scopus differ in general terms in scope and coverage policies, both systems are complementary and not exclusive. In the specific area of wastewater management, Scopus is the base that provides the best coverage taking into account the number of articles published and the number of citations received.

In this article, the results of the bibliometric analysis applied to research on "Water Governance" are presented in order to observe behavior patterns in the key areas of this field of knowledge (progression, most productive authors, etc.). This research is complemented with a co-citation analysis. When considering two databases, a comparative study is carried out between both databases through coverage, overlap, dispersion, or concentration indicators. The results indicate that this area of knowledge has evolved rapidly and has gained popularity and importance among researchers, especially since 2009, when the real boom of the discipline took place, with about two-thirds of the papers being published in the last five years. The main authors, the most relevant articles based on the citation criterion, the institutions, and countries with the highest number of investigations and the journals where this topic is published are also identified. Scopus is the database that performs better coverage by collecting a higher number of articles and obtaining a greater number of citations. [ABSTRACT FROM AUTHOR]
