This paper provides new causal evidence on the effects of gender congruence in the student-adviser relationship on three key student outcomes: (i) retention; (ii) grades; and (iii) post-graduation career outcomes. In so doing, we use unique administrative data from a selective liberal arts...

Peculiar vibrational modes of graphene nanoribbons (GNRs) with topological line defects were presented. We find that phonon dispersion relations of the topological defective GNRs are more similar to those of perfect armchair-edge GNR than to zigzag-edge GNR in spite of their zigzag edge. All...

This article examines the quantitative effects of the Chinese fiscal system on the increasing regional income inequality in China, from 1978 to 2007. Fiscal decentralization is a multifaceted concept not likely to be captured by a single measure. This paper investigates the evolution of three...

TiCl4/MgCl2, TiCl4/MgCl2/donor catalysts and TiCl4/donor complexes were prepared in this experiment; the donors are EB, DNBP, DBPG, DBW, PPDE, and BMMF respectively. Chemical states of Ti on the surface of MgCl2-supported Z–N catalysts were analyzed with X-ray photoelectron spectroscopy (XPS)....
