Thematic evolution maps for the periods 2014–2023. Thematic maps obtained for each period; top right quadrant: motor themes (1), bottom right quadrant: basic themes (2), bottom left quadrant: emerging or declining themes (3), top left quadrant: highly specialized/niche themes (4). When assessing findings, it is important to consider motor themes, which represent the primary and prominent themes in a research field, often reflecting widely studied topics across numerous studies. In contrast, niche themes typically signify narrower or more specialized subjects focused on specific areas of interest, often representing new and emerging research topics compared to motor themes.
