The thematic map with four-quadrants has the vertical axis labeled “Development degree (Density)” and the horizontal axis labeled “Relevance degree (Centrality).” The quadrants are labeled as “Niche Themes” (top left), “Motor Themes” (top right), “Emerging or Declining Themes” (bottom left), and “Basic Themes” (bottom right). Each quadrant contains colored bubbles of varying sizes, each accompanied by a set of terms. In the “Niche Themes” quadrant (top left), a bubble at the top contains the terms “digital technologies” and “human resource development.” A bubble below it has the terms “electronic human resource management” and “knowledge-oriented leadership.” In the “Motor Themes” quadrant (top right), a large bubble at the top right contains the terms “industry 4.0,” “human resource management,” and “sustainability.” A large bubble below it overlaps with the bottom right quadrant, and contains the terms “0,” “industry 4,” and “digital transformation.” On the left, a smaller bubble has the terms “digitalization,” “digitization,” and “automation.” In the “Emerging or Declining Themes” quadrant (bottom left), a bubble at the bottom contains the term “innovation.” Small bubbles at the top of this quadrant contain the terms “circular economy.” In the “Basic Themes” quadrant (bottom right), a bubble at the top center contains the terms “sustainable human resource management” and “challenges.” A bubble near the bottom center contains the terms “sustainable development” and “corporate social responsibility”.Thematic map-Industrial 4.0 and human resource management.
