The network consists of circular nodes representing authors, with node size reflecting citation strength and connecting lines indicating co-citation relationships. Nodes are grouped by color to show clusters of authors who are often cited together. At the center of the network is a dense cluster of green and blue nodes with two prominently large labels: “hall c m 2019” and “boluk k a 2019”, indicating these authors have the highest co-citation frequency. The central cluster includes green-colored nodes such as “scheyvens r 2016”, “budenau a 2016”, “baum t 2016-1”, “higgins-desbiolles f 2020”, “peter j 2017”, “bramwell b 1993”, “higgins-disbiolles f 2006”, “gossling s 2021”, “united nations”, “noluk k 2017”, “un generl 2015”, “movono a 2022”, and “international labour”. To the left of the central mass is a blue cluster containing nodes including “lenzen m 2018”, “brammer b 2011”, “byrd e t 2007”, “le blanc 2015”, “wango vm 2013”, “hall c m 2011”, “united nations 2015-2”, “butler r 1999”, “manyar o g 2007”, “scheyvens r 2019”, and “w c e d 1987”. These nodes are linked with medium-strength co-citation lines. A red cluster appears below the center with authors such as “alarcon d m 2019”, “robinson m s 2019”, “baum t 2018”, “baum t 2016-2”, “figueroa-domecq c 2016”, “scheyvens r. 2000”, “braun v. 2000”, and “movono a 2021”. These nodes are connected closely, indicating shared citations in multiple documents. Small peripheral clusters appear at the edges. A purple group on the lower left includes “scheyvens r 2012” and “mahadevan r 2019”.Author co-citation network of documents. Source: Developed by authors
