“…Niche themes, in turn, include five much smaller clusters, three of which ("management accounting information system", "methods in accounting research", "outsourcing") have the same indices of rank density (5.5) and cluster frequency (2), due to which they completely overlap each other, and also overlap with the fourth cluster ("accounting information system quality"), which has the same rank density (5.5), but a much higher cluster frequency ( 5). This circumstance determines a certain thematic affinity of the publications in the above-mentioned clusters, which were devoted to researching the concept of AIS quality (Anggadini, 2015;Rapina, 2015), the productivity of management accounting software products and the factors that influence them (Choe, 1998;Napitupulu, 2015), and as well as a comparative assessment of the effectiveness of the alternative of implementing and supporting AIS through outsourcing (O'Connor & Martinsons, 2006;Cullinan & Zheng, 2015). The specificity of the qualitative characteristics of AIS requires the use of unique research methods, including the Delphi method (to determine the impact of IT risks on business processes and management areas) (Worrell et al, 2013a) and social network analysis (to study the interaction of AIS with other network nodes and impact on organizational outcomes and company performance) (Worrell et al, 2013b).…”
