“…A better practice is to search all articles in all SLA related journals indexed in the WoS database, as done in a recent bibliometric study of applied linguistics [41]. Second, as found in a number of studies, automated search results are not error-free [104][105][106]. Although this study has refined the search results to "linguistics or education educational research or language linguistics" categories, some erroneous entries may still exist within the dataset.…”

This study aims to provide a comprehensive and data-driven review of the knowledge domain of second language acquisition (SLA) and pedagogy in the past 30 years. Using knowledge domain visualization techniques, the study first provides a review of SLA at the disciplinary level. It then identifies the major research areas and current research frontiers in the SLA research landscape based on high-quality data retrieved from Web of Science (WoS) databases. The study provides useful references for future research and pedagogy in the field in which literature reviews employing scientometric methodology and driven by data, such as the present one, are rare, and thus, are much in need of supplement views produced by traditional literature reviews.

“…Using the query string ‘ISSN(2071‐1050) AND (LIMIT‐TO(PUBYEAR,2015))’, the abstracting and indexing database provides 843 results. It deserves mentioning that at least one of the results is a duplicated item, probably due to matching issues within the indexing engine (Franceschini, Maisano, & Mastrogiacomo, , ; Meester, Colledge, & Dyas, ), and one is a correction. Therefore, the number of articles analysed here is equal to 841.…”

On the skewness of journal self‐citations and publisher self‐citations: Cues for discussion from a case study

This paper takes the cue from the case of a retracted paper, cited both by the retraction notice and by an article published later in the same journal. This led to analysis and discussion on the skewness of citations in the journal Sustainability and within Multidisciplinary Digital Publishing Institute (MDPI) journals, particularly investigating self‐citations at journal and publisher levels. I analysed articles published by Sustainability in 2015 and found that self‐citations are higher than expected under a uniform probability distribution. Self‐citations in this journal make a 36% difference to the journal's impact factor. This research raises the question of what citation patterns can be expected as normal, and where the boundary between normal and anomaly lies. I suggest the issue deserves further investigation because self‐citations have several implications, ranging from impact factors to visibility and influence of scientific journals.

“…During the data verification process, some inconsistencies were detected. Nevertheless, this is a common problem of large databases given that they contain a huge amount of information from a variety of sources [35,36].…”

Power Quality: Scientific Collaboration Networks and Research Trends

et al. 2018

View full text Add to dashboard Cite

Power quality is a research field related to the proper operation of devices and technological equipment in industry, service, and domestic activities. The level of power quality is determined by variations in voltage, frequency, and waveforms with respect to reference values. These variations correspond to different types of disturbances, including power fluctuations, interruptions, and transients. Several studies have been focused on analysing power quality issues. However, there is a lack of studies on the analysis of both the trending topics and the scientific collaboration network underlying the field of power quality. To address these aspects, an advanced model is used to retrieve data from publications related to power quality and analyse this information using a graph visualisation software and statistical tools. The results suggest that research interests are mainly focused on the analysis of power quality problems and mitigation techniques. Furthermore, they are observed important collaboration networks between researchers within and across countries.
