As a result of extreme modifications in human activity during the COVID-19 pandemic, the status of air quality has recently been improved. This bibliometric study was conducted on a global scale to quantify the impact of the COVID-19 pandemic on air pollution, identify the emerging challenges, and discuss the future perspectives during the course of the ongoing COVID-19 pandemic. For this, we have estimated the scientific production trends between 2020 and 2021 and investigated the contributions of countries, institutions, authors, and most prominent journals metrics network analysis on the topic of COVID-19 combined with air pollution research spanning the period between January 01, 2020, and June 21, 2021. The search strategy retrieved a wide range of 2003 studies published in scientific journals from the Web of Sciences Core Collection (WoSCC). The findings indicated that (1) publications on COVID-19 pandemic and air pollution were 990 (research articles) in 2021 with 1870 citations; however, the year 2020 witnessed only 830 research articles with a large number 16,600 of citations. (2) China ranked first in the number of publications ( n = 365; 18.22% of the global output) and was the main country in international cooperation network, followed by the USA ( n = 278; 13.87% of the global output) and India ( n = 216; 10.78 of the total articles). (3) By exploring the co-occurrence and links strengths of keywords “COVID-19” (1075; 1092), “air pollution” (286; 771), “SARS-COV-2” (252; 1986). (4) The lessons deduced from the COVID-19 pandemic provide defined measures to reduce air pollution globally. The outcomes of the present study also provide useful guidelines for future research programs and constitute a baseline for researchers in the domain of environmental and health sciences to estimate the potential impact of the COVID-19 pandemic on air pollution.

“…Note Bibliometric analysis was conducted for only 443 (primary) documents as 73 (secondary) documents lack full data (affiliation, abstract and keywords) bibliometric data was sufficient, but only 443 ECR articles were included in science mapping (e.g., co-authorship, bibliographic coupling, and keyword analyses using VOSviewer [23] and Gephi [24]) as full bibliometric data was required. This collection of articles met the minimum sample size of 200 articles for bibliometric analysis recommended by Rogers, Szomszor, and Adams [25].…”

2021 marks the 20th anniversary of the founding of Electronic Commerce Research ( ECR ). The journal has changed substantially over its life, reflecting the wider changes in the tools and commercial focus of electronic commerce. ECR ’s early focus was telecommunications and electronic commerce. After reorganization and new editorship in 2014, that focus expanded to embrace emerging tools, business models, and applications in electronic commerce, with an emphasis on the innovations and the vibrant growth of electronic commerce in Asia. Over this time, ECR ’s impact and volume of publications have grown rapidly, and ECR is considered one of the premier journals in its discipline. This invited research summarizes the evolution of ECR ’s research focus over its history.

“…It is generally accepted that citations should be normalized by year of publication, discipline, and document type, although whether the calculation should be based on the average of ratios (Opthof & Leydesdorff, 2010;Waltman et al, 2011) or ratio of averages (Moed, 2010;Vinkler, 2012) is contentious (Larivière & Gingras, 2011), as is the selection of counting methodology (Potter et al, 2020;Waltman & van Eck, 2015). Suitable sample size is key to providing robust outcomes (Rogers et al, 2020), and any choices made with respect to category scheme used and indicator choice should influence interpretation of results (Szomszor et al, 2021).…”

This paper presents an analysis of the Overton policy document database, describing the makeup of materials indexed and the nature in which they cite academic literature. We report on various aspects of the data, including growth, geographic spread, language representation, the range of policy source types included, and the availability of citation links in documents. Longitudinal analysis over established journal category schemes is used to reveal the scale and disciplinary focus of citations and determine the feasibility of developing field-normalized citation indicators. We examine how well self-reported funding outcomes collected by UK funders corresponds to data indexed in the Overton database, and if peer-review assessment of impact as measured by the UK Research Excellence Framework (REF) 2014 correlates with derived citation metrics. Our findings show that for some research topics, such as health, economics, social care and the environment, Overton contains a core set of policy documents with sufficient citation linkage to academic literature to support various citation analysis that may be informative in research evaluation, impact assessment, and policy review. The data indexed in Overton agrees with that collected via self-reporting of funding outcomes, and correlates with peer-review assessment of impact in some disciplines.
