Hypotheses

• No criterion is sufficient by itself
• Each criterion yields different measures of
  internationality
• Some criteria are difficult to quantify
• In the absence of a multi-criteria, single-valued
  index, internationality remains a highly
  subjective and ambiguous estimate based on a
  biased choice of evaluation criteria

Conclusion

• Journal Internationality cannot be measured
  unambiguously by the assessment of individual
  criteria
• Need for a multi-criteria, single-valued Journal
  Internationality Index

With the new JII we will be able to

• Quantitatively measure internationality
• Qualitatively define Internationality
• Re-assess academic journals
