Asset management is not new, and research has been conducted in private and public sectors on how to systematically maintain infrastructure or facilities for sustainable use and achieve the level of service desired by users or customers at the lowest life cycle costs. This research identifies the research topics and trends in asset management over the past 30 years. To this end, latent Dirichlet allocation, a topic modeling approach, was applied to articles published in engineering journals and investigated the following three research questions: (1) what have the key topics been for the past three decades? (2) what are the main activities and target sectors of asset management? (3) how have the research topics and keywords changed over the past three decades? The analysis shows that the target field of asset management has broadened while the main activities of asset management have been limited to several popular activities such as life cycle cost analysis and reliability analysis. Some implications and future research directions are also discussed.

Biochemical Research

Biochemistry has been broadly defined as “chemistry of molecules included or related to living systems”, but is becoming increasingly hard to be distinguished from other related fields. Targets of its studies evolve rapidly; some newly emerge, disappear, combine, or resurface themselves with a fresh viewpoint. Methodologies for biochemistry have been extremely diversified, thanks particularly to those adopted from molecular biology, synthetic chemistry, and biophysics. Therefore, this paper adopts topic modeling, a text mining technique, to identify the research topics in the field of biochemistry over the past twenty years and quantitatively analyze the changes in its trends. The results of the topic modeling analysis obtained through this study will provide a helpful tool for researchers, journal editors, publishers, and funding agencies to understand the connections among the diverse sub-fields in biochemical research and even see how the research topics branch out and integrate with other fields.

Perfectionism is a personality characteristic that has been explored for its implications in mental health; reviews and meta-analyses were conducted to synthesize research findings. This study systemically synthesizes the perfectionism literature using a text-mining approach. Co-word analysis and Dirichlet Multinomial Regression topic modeling were performed on a total of 1,529 perfectionism abstracts published from 1990 to 2019. Analysis revealed that perfectionism research is closely connected with “disorder,” with “symptom” being the most frequently addressed issue. Topic-modeling results found a total of 15 topics represented perfectionism research of the past three decades. Most articles were published in psychology journals, with social and clinical psychology subdisciplines publishing perfectionism articles most frequently. There were overlaps in research topics by journal subdisciplines, while differences were also observed. This study provides a panoramic view of perfectionism literature and highlights frequently and infrequently explored areas that could be considered in future research endeavors.

This paper aims at examining how overtourism and tourismphobia are being approached as emergent research topics in current tourism literature. It conducts an analysis of 154 documents, indexed in the Web of Science (WoS) Core Collection and Scopus databases. The study follows a quantitative and qualitative approach, with the support of VOSviewer and HistCite softwares for a descriptive content analysis. The analysis focuses on highlighting important aspects in terms of the most frequent publication sources (authors and journals); co-citation, as well as dimensions and research streams; methodologies used; results obtained; and implications for future research. The literature review unveiled that the concepts of overtourism and tourismphobia are usually related to destinations’ development, negative impacts, and tourism policies and regulation. Results show that, although tourism excesses and conflicts have been studied for long, ‘overtourism’ and ‘tourismphobia’ have become usual terms, mainly within the past three years. Even though the adoption of the terms can be considered by some as a ‘trend’, the in-depth analysis of the topics shed light on how ‘old’ concepts can evolve to adapt to contemporary tourism issues. Further studies are needed in tracking the evolution of these topics and their implications on the future of tourism.

Abstract The spout-fluid bed (SFB) is a very successful synthesis of the spouting and fluidization. The hydrodynamics of SFB are more complex than both fluidized beds and spouted beds. Up-to-date information on the fundamentals and applications of SFBs has been briefly presented, based on the limited work reported, in the new spouted bed book edited by Norman Epstein and John R. Grace (Spouted and spout-fluid beds: fundamentals and applications, 2011). In the past three years, nearly 30 papers have been published in international journals. They reported interesting studies on hydrodynamic characteristics, numerical simulations and new applications of SFBs. This article reviews the major research and development on SFB from the year 2010 and recommends further research topics. This review is intended not only as an important supplement to the SFB chapter of the spouted bed book but also helpful guidance for future research.

Purpose The purpose of this paper is to provide a broad preliminary overview and critical viewpoint on the current state of customer experience innovation and strategy in Thailand. Design/methodology/approach This paper outlines and critically analyses the key trends based on 15 prime instances of customer experience innovation from the past ten years in Thailand across three industries: retail, fuel service and insurance. Findings Customer experience in Thailand is still in its nascent stage. This is because firms are yet to realise their full potential as critical brand differentiators. Many Thai firms also miss collaboration opportunities with external partners when innovating customer experiences. This is despite the overwhelming contributions from local SMEs to breakthrough innovations and creativity. Consequently, many customer experience innovations in Thailand are yet to be truly memorable and unique. Originality/value This is the first paper that critically examines the trends in customer experience across the retail, fuel service and insurance. It is also the only paper that outlines strategic implications of customer experience strategies and innovations to date for Thailand. Both future research topics and managerial implications for Thai professionals are discussed in the paper.

Research Fronts

Abstract Background: Medical informatics (MI) is a multidisciplinary field in which researchers pursue scientific exploration, problem-solving, and decision-making to facilitate the effective use of biomedical data, information and knowledge for the improvement of human health. The purpose of this study is to identify research fronts in the field of MI and ultimately elucidate research activities and trends in this field. Methods: This study used topic model to identify research topics in the field of MI based on the latent Dirichlet allocation method (LDA). And the topic cloud is utilized to visualize the research topics. For identifying the research front topics, we proposed the indicators of identifying research front topics. In addition, we investigated how front topics change over time, and divided them into five categories based on the life cycle theory. Results: The data were collected from 35981 published journal abstracts between 2007 and 2016. In the topic distribution of MI, we found that the scope of MI related research has become increasingly interdisciplinary, particular for medical data analysis. Also, in the analysis of research fronts of MI, we found that the use of natural language processing and medical text knowledge extraction play an essential role for systematic analysis and indexing of the underlying semantic contents. Conclusions: By categorizing the research fronts, the results shows that there are twelve growing, five stable and two declining research fronts. We hope that this work will facilitate greater exploration of the method of identifying the research fronts. Moreover, the findings of this study provide an insight on the research fronts and trends in MI.

Abstract Background The rapid decrease in international funding for HIV/AIDS has been challenging for many nations to effectively mobilize and allocate their limited resources for HIV/AIDS programs. Economic evaluations can help inform decisions and strategic planning. This study aims to examine the trends and patterns in economic evaluation studies in the field of HIV/AIDS and determine their research landscapes. Methods Using the Web of Science databases, we synthesized the number of papers and citations on HIV/AIDS and economic evaluation from 1990 to 2017. Collaborations between authors and countries, networks of keywords and research topics were visualized using frequency of co-occurrence and Jaccards’ similarity index. A Latent Dirichlet Allocation (LDA) analysis to categorize papers into different topics/themes. Results A total of 372 economic evaluation papers were selected, including 351 cost-effectiveness analyses (CEA), 11 cost-utility analyses (CUA), 12 cost-benefit analyses (CBA). The growth of publications, their citations and usages have increased remarkably over the years. Major research topics in economic evaluation studies consisted of antiretroviral therapy (ART) initiation and treatment; drug use prevention interventions and prevention of mother-to-child transmission interventions. Moreover, lack of contextualized evidence was found in specific settings with high burden HIV epidemics, as well as emerging most-at-risk populations such as trans-genders or migrants. Conclusion This study highlights the knowledge and geographical discrepancies in HIV/AIDS economic evaluation literature. Future research directions are also informed for advancing economic evaluation in HIV/AIDS research.

Methylmercury Exposure

AbstractProtecting the environment and enhancing food security are among the world’s greatest challenges. Fish consumption is widely considered to be the single significant dietary source of methylmercury. Nevertheless, by synthesizing data from the past six decades and using a variety of models, we find that rice could be a significant global dietary source of human methylmercury exposure, especially in South and Southeast Asia. In 2013, globalization caused 9.9% of human methylmercury exposure via the international rice trade and significantly aggravated rice-derived exposure in Africa (62%), Central Asia (98%) and Europe (42%). In 2016, 180 metric tons of mercury were generated in rice plants, 14-fold greater than that exported from oceans via global fisheries. We suggest that future research should consider both the joint ingestion of rice with fish and the food trade in methylmercury exposure assessments, and anthropogenic biovectors such as crops should be considered in the global mercury cycle.
