New Urban Sociology began in Europe at the beginning of the 1970s and then spread to the United States. It also influenced urban studies in Japan. This article examines the changing debates that have occurred in New Urban Sociology since its introduction to Japan in the late 1970s. The twenty years since its introduction from the West can be divided into three stages. The first covers the period from 1977 to 1985, when French urban sociology, particularly Manuael Castells' theory of the state, was highly influential. The second stage, from 1986 to 1992, focused on theories of urban social movements and the concept of global city in a context of urban renewal in Japan's major cities. The third stage, from 1992 to the present, is characterized by a transformation of New Urban Sociology into a sociological theory of space under globalization that has been heavily influenced by the work of David Harvey.

A series of Sn-substituted strontium ferrate SrFe1-xSnxO3-δ (x = 0, 0.25, 0.50, 0.75 and 1.0) were prepared by the polymerized complex method. Influence of the substitution of Fe in SrFeO3-δ...
A new method is proposed for the detection and characterization of bubble clusters in the framework of Euler-Lagrange simulations. It is based on the definition of the smoothed void fraction which depends only on geometrical information, i.e. on the bubble positions. Two variants are proposed, one in an Eulerian fashion and a more efficient one in a Lagrangian style. Both techniques are applied to a vertical channel flow laden with monodispersed bubbles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
