The Trend of Bacterial Nanocellulose Research Published in the Science Citation Index Expanded From 2005 to 2020: A Bibliometric Analysis

To gain insight into the trend of bacterial nanocellulose research, a bibliometric analysis was performed using the Science Citation Index Expanded database from 2005 to 2020. The study concentrated on the publication’s performance in terms of annual outputs and citations, mainstream journals, categories of the Web of Sciences, leading countries, prominent institutions, and trends in research. Current research priorities and future trends were analyzed after summarizing the most commonly used keywords extracted from words in the paper title analysis, authors’ keyword analysis, and KeyWords Plus. The findings revealed that the annual output in the form of scholarly articles on bacterial nanocellulose research steadily increased during the first quartile of the study period, followed by a very rapid increase in the last five-years of the study. Increasing mechanical strength would remain the main future focus of bacterial nanocellulose research to create its scope in different field of applications.

Intangible Cultural Heritage in Tourism: Research Review and Investigation of Future Agenda

Intangible cultural heritage (ICH) can be a valuable tourism resource for both government and local communities. However, the complex definition and the massive and fragmented nature of ICH data make it hard to review and conclude research trends and future directions of ICH tourism. In this study, 85 keywords extracted from ICH definitions are input in the Web of Science database before collecting papers indexed in the Social Sciences Citation Index, the Arts and Humanities Citation Index, and the Conference Proceedings Citation Index-Social Science and Humanities. Later, a systematic literature review of 418 ICH tourism studies from 76 countries published between 2000 and 2021 were conducted based on three groups of questions. The findings mainly illustrated that: (1) Currently research in ICH tourism is mainly composed of three themes: resource planning and sustainability, the impact of tourism development, and tourist behavior and destination marketing; (2) topics related to food tourism, sacred knowledge, traditional management systems, traditional management systems, legends, and myths can achieve high impact; (3) in the last five years, scholars have reduced using the official full name of ICH in tourism studies, while the category of “social practices, rituals and festive events” has become a hot topic since 2010; (4) ecotourism, culinary tourism, festival tourism, and religious tourism are the most discussed in ICH tourism research, and they will still be intensive topics in near future; (5) future directions in ICH tourism research are resultant of three vectors: place making, technology, and environment. The results present a comprehensive picture of current popular ICH topics and predict future directions in the field of ICH tourism. The systematic review of literature can help contribute to both theoretical construction, heritage preservation, and tourism practices.

Scopus 1900–2020: Growth in articles, abstracts, countries, fields, and journals

Scientometric research often relies on large-scale bibliometric databases of academic journal articles. Long term and longitudinal research can be affected if the composition of a database varies over time, and text processing research can be affected if the percentage of articles with abstracts changes. This article therefore assesses changes in the magnitude of the coverage of a major citation index, Scopus, over 121 years from 1900. The results show sustained exponential growth from 1900, except for dips during both world wars, and with increased growth after 2004. Over the same period, the percentage of articles with 500+ character abstracts increased from 1% to 95%. The number of different journals in Scopus also increased exponentially, but slowing down from 2010, with the number of articles per journal being approximately constant until 1980, then tripling due to megajournals and online-only publishing. The breadth of Scopus, in terms of the number of narrow fields with substantial numbers of articles, simultaneously increased from one field having 1000 articles in 1945 to 308 in 2020. Scopus’s international character also radically changed from 68% of first authors from Germany and the USA in 1900 to just 17% in 2020, with China dominating (25%).

Scientometric engineering: Exploring citation dynamics via arXiv eprints

Scholarly communications have been rapidly integrated into digitised and networked open ecosystems, where preprint servers have played a pivotal role in accelerating the knowledge transfer processes. However, quantitative evidence is scarce regarding how this paradigm shift beyond the traditional journal publication system has affected the dynamics of collective attention on science. To address this issue, we investigate the citation data of more than 1.5 million eprints on arXiv (https://arxiv.org) and analyse the long-term citation trend for each discipline involved. We find that the typical growth and obsolescence patterns vary across disciplines, reflecting different publication and communication practices. The results provide unique evidence on the attention dynamics shaped by the research community today, including the dramatic growth and fast obsolescence of Computer Science eprints, which has not been captured in previous studies relying on the citation data of journal papers. Subsequently, we develop a quantitatively-and-temporally normalised citation index with an approximately normal distribution, which is useful for comparing citational attention across disciplines and time periods. Further, we derive a stochastic model consistent with the observed quantitative and temporal characteristics of citation growth and obsolescence. The findings and the developed framework open a new avenue for understanding the nature of citation dynamics. Peer Review https://publons.com/publon/10.1162/qss_a_00174

Epicutaneous sensitization. what do we know?

Background. According to the currently existing hypothesis, epicutaneous sensitization is one of the leading mechanisms in the development of food allergy.The aim of this review was to analyze immune mechanisms in epicutaneous sensitization and the role of skin barrier impairment.We performed a literature search using PubMed, UpToDate, Web of Science, and Scopus databases by the key words: epicutaneous sensitization, atopic dermatitis, skin barrier impairment, food allergy. Articles were to be in open access and present the most relevant information on the topic. Studies were selected by the largest sample size and the highest citation index. Once publications were identified, they were reviewed by all the authors to select the studies that specifically addressed the theme of the review. A total of 101 publications from 1998–2000 were included in the study.This review article discusses the data of experimental studies, sets out modern ideas about the hypothesis of a double exposure to an allergen, and presents research data proving the clinical significance of epicutaneous sensitization in relation to food allergy. Knowledge about the mechanisms of epicutaneous sensitization development is necessary to elaborate strategies for prevention of food allergy. One of the modern trends in prevention is the use of emollients, which are supposed to restore the skin response. However, studies on preventive intake of emollients do not present a similar viewpoint.There is not enough evidence for or against the mechanism of epicutaneous sensitization as an indispensable condition for the formation of food allergies. Further research in this area is required.

Variables considered on art therapy assessments and rating instruments: a systematic review

Objectives: Art-based assessments are used by art therapists and sometimes researchers principally to: determine treatments, levels of cognition and functioning, evaluate progress of a client or to understand the client’s environment and problems that can be represented in a graphic level. These art-based assessments use determined evaluation instruments to measure parameters to understand their clients. The rating instruments have different variables and some studies even present their own adapted scales. For this systematic review, the tools examined in the analysis are: The Bird’s Nest Drawing (BND); the Bridge Drawing; the Diagnostic Drawing Series (DDS); the Person Picking an Apple from a Tree (PPAT); and Free Drawing Assessment. Rating instruments are also considered, including the Descriptive Assessment of Psychiatric Art (DAPA), the DDS Rating Guide and Drawing Analysis Form (DAF), the Formal Elements Art Therapy Scale (FEATS) and studies that include their own scale. There are different elements considered when assessing drawings and artwork approaches to make assessment test using art-based and art therapy tools. The principal objective of the present systematic review was to observe the different elements analysed. The specific objectives were; to describe characteristics of this assessments and to observe the elements considered to analyse drawings in order to observe their application and their validity. Methods: Studies available in English were accessed. The following databases were used: AMED, A&HCI, Arts and Humanities Citation Index, Medline, Psych INFO and Google Scholar. Searches covered the periods from database inception to July 2021 on art therapy and art-based assessment diagnose tools. Results: There were different variables used in art therapy and art based assessment diagnose tools. There were some variables that related or were named differently un some studies. However, there were other variables that were considered in some studies, while in other ones where not. To analyse the assessment the majority were using qualitative and observational technics, a few studies did not share their analysis, in this kind of studies only a thematic analysis or other type of analysis where developed studied. Descriptive results and synthesis outcomes reveal that art therapists are still in a nascent stage of understanding assessments and rating instruments, that flaws in the art therapy assessment and rating instrument literature research are numerous, and that much work has yet to be done. Conclusions: Descriptive results and synthesis revel that some studies have some limitations in some studies regarding to the content that is and how is analysed. Art therapy and art-based studies stills in a nascent stage of understanding the variables considered when using rating instruments. This systematic review also contributes as there are flaws in the art therapy and art-based rating instruments are numerous. There is a limited evidence on studies related with assessment diagnose tools and the reliability of some scales.

A Bibliometric and Visualization Analysis of Mindfulness and Meditation Research from 1900 to 2021

This study comprehensively summarizes research in the field of meditation, especially mindfulness meditation from 1900 to 2021, by analyzing the knowledge map through CiteSpace and VOSviewer software. Using “mindfulness *” or “meditation *” as the topic, articles included in the Science Citation Index Expanded and Social Sciences Citation Index were searched in the web of science core database, resulting in the selection of 19,752 articles. Over half a century ago, Deikman published the field’s first article in the Journal of Nervous and Mental Disease in 1963, and publications have soared in subsequent decades. The USA is in the core position in terms of global collaboration, total publication numbers, and total citations. The Mindfulness journal ranked first for the most published articles and citations. “The benefits of being present: Mindfulness and its role in psychological well-being,” written by Brown and Ryan, was the most cited article. Mindfulness, meditation, depression, intervention, stress reduction, stress, and anxiety are the top co-occurrence keywords. The timeline of cluster analysis discloses that before 2010, hypertension, cancer, mindfulness, generalized anxiety disorder, and other topics received great attention. In the decade since 2010, scholars have shown interest in meta-analysis, attention, and self-assessment, and keen attention to mindfulness-based interventions. These findings provide an important foundation to direct future research.

Data and code availability statements in systematic reviews of interventions are often missing or inaccurate: a content analysis

Objectives: To estimate the frequency of data and code availability statements in a random sample of systematic reviews with meta-analysis of aggregate data, summarise the content of the statements and investigate how often data and code files were shared. Methods: We searched for systematic reviews with meta-analysis of aggregate data on the effects of a health, social, behavioural or educational intervention that were indexed in PubMed, Education Collection via ProQuest, Scopus via Elsevier, and Social Sciences Citation Index and Science Citation Index Expanded via Web of Science during a four-week period (between November 2nd and December 2nd, 2020). Records were randomly sorted and screened independently by two authors until our target sample of 300 systematic reviews was reached. Two authors independently recorded whether a data or code availability statement (or both) appeared in each review and coded the content of the statements using an inductive approach. Results: Of the 300 included systematic reviews with meta-analysis, 86 (29%) had a data availability statement and seven (2%) had both a data and code availability statement. In 12/93 (13%) data availability statements, authors stated that data files were available for download from the journal website or a data repository, which we verified as being true. While 39/93 (42%) authors stated data were available upon request, 37/93 (40%) implied that sharing of data files was not necessary or applicable to them, most often because "all data appear in the article" or "no datasets were generated or analysed". Discussion: Data and code availability statements appear infrequently in systematic review manuscripts. Authors who do provide a data availability statement often incorrectly imply that data sharing is not applicable to systematic reviews. Our results suggest the need for various interventions to increase data and code sharing by systematic reviewers.
