In this review of ten years of social innovation research(2012e2022),we define and explore three paradigms in the field:instrumentalist,strong,and *** investigate how language usage and geography play a central role in identifying which paradigms recently published scholarship falls *** we do not insist that sharp divisions exist between each paradigm,we do find that on the“instrumentalist”side,language tends to abstract or neutralize power ***,these perspectives tend to derive from Western or eurocentric orientations or ***“strong”paradigm accepts the necessity of institutional and stakeholder engagement and seeks to engage socially excluded *** contrast,geographical diversity,attendance to historicized and systemic inequalities,and elevation of the most marginalized communities are more likely to be centered in the“democratic”*** apply this discussion to recent research in arts-related social innovation and the related field of social entrepreneurship.

The behavior of electrons in ordinary metals is dominated by physics near the Fermi surface. Indeed, many of the first successes of the quantum theory of solids, such as understanding the large specific heat of metals, followed from applications of the Fermi surface concept. Great effort has been devoted in recent years to semimetals in which the Fermi surface shrinks to a set of Dirac or Weyl points, where four
