AAS Institutional Presence

About This Visualization
Methodology

This visualization examines which academic institutions have been represented at Association for Asian Studies (AAS) conferences through panels and papers on Japan. Data spans 1995–2025, covering 21 conference years.

Three complementary views reveal different aspects of institutional participation:

  • The heatmap shows the top 25 institutions across all conference years, with cell intensity reflecting presentation count.
  • The bar chart race animates cumulative institutional contributions over time, revealing which institutions have sustained or accelerated their presence.
  • The bump chart tracks rank trajectories for the top 20 institutions, showing which departments have risen or fallen in relative participation.

The sidebar provides concentration metrics (top-5 share by era), geographic breakdowns (US, Japan, and international), and new institutional appearances each year. Institutions are colored with their official university brand colors where available.

Data Source

Institution data comes from presenter self-reported affiliations in AAS conference programs and proceedings.

Normalization

Raw institution strings are processed through a multi-stage pipeline: alias lookup (~200 canonical mappings), prefix normalization for university systems (UC, SUNY, etc.), and artifact removal (trailing colons, concatenated titles, role prefixes). Entries that are clearly not institutions (independent scholars, freelance, etc.) are excluded.

School Colors

The top institutions receive colors matching their official brand palettes. Colors adjust for dark mode to ensure visibility. Institutions without defined brand colors appear in grey.

Metrics

The top-5 concentration percentage shows what share of all institutional presentations came from the five most active institutions in each era. Higher values indicate more concentrated participation.

Limitations

  • Institution names are self-reported and may include department names or research centers despite normalization efforts.
  • Some institutions may appear under multiple variant names that are not fully consolidated.
  • Presentations without affiliation data are excluded from institutional counts.
