Mapping interdisciplinary fields: efficiencies, gaps and redundancies in HIV/AIDS research

Area of Science:

• Bibliometrics
• Scientometrics
• Health Sciences
• Social Sciences

Background:

• Interdisciplinarity is increasingly encouraged in science funding and policy.
• However, its actual impact on scientific advancement, particularly in complex fields like HIV/AIDS research, is not well understood.
• A critical examination of disciplinary integration is needed to understand knowledge gaps and unresolved questions.

Purpose of the Study:

• To analyze the dynamics of disciplinary integration within HIV/AIDS research over two decades.
• To investigate how different research topics integrate or remain segregated across disciplinary boundaries.
• To challenge simplistic or static views of interdisciplinarity.

Main Methods:

• Bibliographic coupling networks were constructed using citation data from two interdisciplinary journals.
• Topic modeling was employed to analyze the content of research within the field.
• The evolution of research clusters and topic structures over 20 years was compared.

Main Results:

• Bibliographic coupling revealed distinct research clusters, indicating varying levels of disciplinary segregation.
• Topic models showed that some areas, like vaccine development, exhibited increasing cross-disciplinary coordination.
• Other areas, such as drug resistance, remained consistently segmented within disciplinary domains throughout the study period.

Conclusions:

• Interdisciplinarity in HIV/AIDS research is heterogeneous, with different topics integrating at different rates.
• The findings challenge one-dimensional and cross-sectional analyses of scientific collaboration.
• A nuanced approach is essential for understanding the organization of science and fostering effective interdisciplinary research.
