Tourism represents one of the main industries in terms of job creation and economic development while sustainability in tourism represents a worldwide challenge. The objective of the present study is to use a bibliometric approach to review the relevant literature. Bibliometric indicators, such as citations, are used to identify the field structure and the VOSviewer software is used to map the main trends in this area. Over the period 1987–2018, a total of 4647 papers were found in Scopus regarding sustainability issues in tourism. Analysis of the leading journals, authors, institutions, and keywords indicates that: (1) the literature on sustainability issues in the field of tourism is significantly growing; (2) a mere six papers accounted more than 300 citations, but there are several prolific authors; (3) of the 614 sources included in the review, the most important have published 46.7% of the papers; (4) in terms of documents and citations, the United States is the leading country in this topic; (5) according to keyword trend network analysis, sustainability is becoming a strategic approach for companies and tourist destinations. Finally, this subfield within the tourism literature has considerable potential and is expected to continue growing.

This paper reviews the literature on online reviews in tourism and hospitality, and presents the current state of research in the area. A bibliometric approach was used to analyze 632 journal articles on online reviews in tourism and hospitality from 2005 to 2019 from the Scopus Database. This study identifies the most prolific journals, foundational works, and major research themes in the research area. In addition, we analyzed some dimensions of their network structure and the thematic evolution of the research area. The bibliometric method is quantitative and objective, and we carry out an analysis of the area based on citations and keywords. Researchers and business managers can gain useful insights on the current state of the art in this area. There have been only a few literature reviews tracking the growth in this research area, and even fewer using bibliometric methods or science maps. Therefore, this work provides an updated review of this fast-growing area with a bibliometric approach to highlight the recent developments with the aid of science maps, and shows the thematic network structure and evolution with an innovative visualization.

Purpose – The aim of this paper is to provide empirical guidance on those antecedents and consequences of customer satisfaction (CS) that may be included in the tourism sector and based on a systematic literature review. Design/methodology/approach – Undertaken through a review of 495 papers that have been published in 41 journals since 1988 and up to 2016 (a 29-year period). A more detailed understanding and discussion is also provided, which has been based on the analysis of the 100 most-cited articles. Findings – The theoretical models and the empirical applications provided depend to some extent on the sector under analysis. Nevertheless, the most popular determinants and consequences are service quality and loyalty (recommendation and revisiting), respectively. CS antecedents have been studied more than CS consequences. Research limitations/implications – The analysis has been based solely on English language articles that appear in Scopus. As a result, the geographical areas and the tourist sectors are definitely biased by this selection, and the results cannot be easily transferred to other geographical areas or tourist sectors. Practical implications – The results obtained from the study have relevant empirical and practical implications for hospitality researchers and practitioners. Firstly, the selected papers may be used as a valid starting point to research CS with respect to antecedents and consequences. Hospitality managers can also benefit from a better understanding of this triplet in tourism. Originality/value – This study is the first attempt to provide a systematic literature review on the antecedents and consequences of CS in tourism. Thus, researchers in the field will be able to begin their work with a complete and comprehensive model that considers the main antecedents and consequences of CS in tourism.

Improving healthcare performance has become a need for resource optimisation in a field where they are scarce. Activity‐Based Costing (ABC) has been applied for more than 30 years to allocate costs and provide information for decision‐making. This paper seeks to review previous literature in the health field that analysed this cost system and its new version, TDABC (Time‐Driven Activity‐Based Costing). Five hundred ninety articles published from 1989 to 2019 were retrieved from Scopus and Medline. The review includes descriptive, relational and content analyses. Results show that the interest in applying these cost systems is growing, especially in journals focusing on the financial aspects of health, policy and planning, and radiology. However, there is a difference in the application of ABC and TDABC. ABC is more related to efficiency and more used in laboratories. In contrast, TDABC is primarily used in hospitals and addressing the value of health rather than cost‐effectiveness. On the other hand, the findings suggest that TDABC present greater opportunities for publication compared with ABC. Its progression is higher and gets more citations. The current article contributes to broadening the field's vision and encourages authors for further research.

Six Sigma is a business management strategy used by many industries for quality improvement. The aim of the study is to conduct a bibliometric and relational study on Six Sigma research indexed in two well-known databases: Scopus and the Web of Science. Data collection involved 798 articles published in 392 academic journals between 1990 and 2017. Studies were classified based on research type (methodology used), authorship (type and country of affiliation), research field and keywords (co-occurrence and trend). Results show that literature on Six Sigma is dominated by the field of business and management followed by engineering and medicine. United States is the leading country in this topic in terms of documents, cites and co-authorships. Case studies and conceptual papers are clearly the most used methodologies, although there is a noticeable upward trend in surveys in the business and management area. Based on the articles’ keywords, it appears that Lean Six Sigma, the combination of the two management approaches, has recently become one of the most common terms, outpacing traditional terms such as Total Quality Management or continuous improvement. For the field to advance, further survey studies are needed as conceptually it has been deeply researched.
