Background The field of software testing is growing and rapidly-evolving. Aims Based on keywords assigned to publications, we seek to identify predominant research topics and understand how they are connected and have evolved. Methods We apply co-word analysis to map the topology of testing research as a network where author-assigned keywords are...

Some states in the U.S. have traditionally received less federal research funding than other states. The National Science Foundation (NSF) created a program in 1979, called the Experimental Program to Stimulate Competitive Research (EPSCoR) to enhance the research competitiveness in such EPSCoR states. While it is well established that the EPSCoR s...

Background: The U.S. Food and Drug Administration (FDA) authorized the marketing of the IQOS tobacco heating system as a modified risk tobacco product (MRTP) in July 2020, permitting its 'reduced exposure' marketing. This decision is accompanied by much controversy among the global health community. We provide a preliminary analysis of Twitter conv...

Background: Little is known about the role of the World Health Organization (WHO) in setting an agenda on social media during a public health emergency such as the COVID-19 pandemic. More specifically, there is no study about the relationship between WHO agenda and the agenda of Twitter users during COVID-19. Objective: This study uses the netwo...

Background: The word “infodemic” refers to the deluge of false information about an event, and it is a global challenge for today’s society. The sheer volume of misinformation circulating during the COVID-19 pandemic has been harmful to people around the world. Therefore, it is important to study different aspects of misinformation related to the p...

Encyclopedias are sometimes cited by scholarly publications, despite concerns about their credibility as sources for academic information. This study investigates trends from 2002 to 2020 in citing two crowdsourced and two expert-based encyclopedias to investigate whether they fit differently into the research landscape: Wikipedia, Britannica, Baid...

Background: Although past research focuses on the COVID-19 related frames in the news media, such research may not accurately capture and represent the perspectives of people from diverse backgrounds. Additionally, the research on the public attention to COVID-19 as reflected through frames on social media is scarce. Objective: This study identi...

BACKGROUND Although past research has focused on COVID-19–related frames in the news media, such research may not accurately capture and represent the perspectives of people from diverse backgrounds. Additionally, research on the public attention to COVID-19 as reflected through frames on social media is scarce. OBJECTIVE This study identified the...

Assigning authorship and recognizing contributions to scholarly works is challenging on many levels. Here we discuss ethical, social, and technical challenges to the concept of authorship that may impede the recognition of contributions to a scholarly work. Recent work in the field of authorship shows that shifting to a more inclusive contributorsh...

Using big data has been a prevailing research trend in various academic fields. However, no studies have explored the scope and structure of big data across disciplines. In this paper, we applied topic modeling and word co-occurrence analysis methods to identify key topics from more than 36,000 big data publications across all academic disciplines...

Although more than a million academic papers have been posted on Facebook, there is little detailed research about which fields or cross-field issues are involved and whether there are field or public interest relationships between Facebook mentions and future citations. In response, we identified health and biomedical scientific papers mentioned o...

Background and Aims The economic value of wine has increased over the years due to the emergence of new producers and new markets. In line with this, the global distribution of research outputs in viticulture and oenology has also shifted since this informs wine production and consumption. This study investigates the trends in wine and grape public...

Over a million journal articles had been shared on public Facebook pages by 2017, but little is known about who is sharing (posting links to) these papers and whether mention counts could be an impact indicator. This study classified users who had posted about 749 links on Facebook before October 2017 mentioning 500 medical and health-related resea...

Reading academic publications is a key scholarly activity. Scholars accessing and recording academic publications online are producing new types of readership data. These include publisher, repository, and academic social network download statistics as well as online reference manager records. This chapter discusses the use of download and referenc...

Although counts of tweets citing academic papers are used as an informal indicator of interest, little is known about who tweets academic papers and who uses Twitter to find scholarly information. Without knowing this, it is difficult to draw useful conclusions from a publication being frequently tweeted. This study surveyed 1,912 users that have t...

This exploratory study examines the strategies of social bots on Twitter that were retweeted following a mass shooting event. Using a case study method to frame our work, we collected over seven million tweets during a one‐month period following a mass shooting in Parkland, Florida. From this dataset, we selected retweets of content generated by ov...

OBJECTIVES/SPECIFIC AIMS: Translational science supports the continuum of activities from early-stage bench research to implementation of discoveries for better and faster treatments to more patients. Past studies have attempted to clarify our understanding of the spectrum of translational research by categorizing the activities into stages ranging...

Altmetrics is an emerging measure for academic impact and it is gaining in global importance. In this paper, we analyse the altmetric landscape of Singapore, a young nation with a fast growing international research sector. We aim to find out if the coverage of altmetrics across the different disciplines is increasing along with the fast increase i...

Although Mendeley bookmarking counts appear to correlate moderately with conventional citation metrics, it is not known whether academic publications are bookmarked in Mendeley in order to be read or not. Without this information, it is not possible to give a confident interpretation of altmetrics derived from Mendeley. In response, a survey of...

Although there is evidence that counting the readers of an article in the social reference site, Mendeley, may help to capture its research impact, the extent to which this is true for different scientific fields is unknown. This study compares Mendeley readership counts with citations for different social sciences and humanities disciplines. The...

Little detailed information is known about who reads research articles and the contexts in which research articles are read. Using data about people who register in Mendeley as readers of articles, this paper explores different types of users of Clinical Medicine, Engineering and Technology, Social Science, Physics and Chemistry papers inside and o...

Faculty of 1000 (F1000) is a post-publishing peer review web site where experts evaluate and rate biomedical publications. F1000 reviewers also assign labels to each paper from a standard list or article types. This research examines the relationship between article types, citation counts and F1000 article factors (FFa). For this purpose, a random...

There is some evidence that counting the readers of an article in the social reference site, Mendeley, may help to capture the research impact of the article, but the extent to which this is true for different scientific fields is unknown. This study compares Mendeley readership counts with citation counts for different social sciences and humaniti...

Nanoscience and technology (NST) is a relatively new interdisciplinary scientific domain, and scholars from a broad range of different disciplines are contributing to it. However, there is an ambiguity in its structure and in the extent of multidisciplinary scientific collaboration of NST. This paper investigates the multidisciplinary patterns of I...
