human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "democracy globalization and science"):
  Abstract: The relationship between democracy and science has long been discussed by scholars. However, the question has not been adequately addressed empirically at the international level. Using panel data on 161 countries over a seven-year period, we estimate the effects of democracy on scientific influence, controlling for globalization, population size, publication output, and level of international research collaboration. The results show that countries with higher levels of democracy tend to have higher impact science.

Includes members:
  Member "the many faces of mobility using bibliometric data to measure the movement of scientists":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "the differing meanings of indicators under different policy contexts the case of internationalisation")
  Member "field normalized citation impact indicators and the choice of an appropriate counting method":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "china may need to support more small teams in scientific research")
