“…In contrast to these steady peaks, new peaks appeared in Tachikawa and Akishima cities after 1998 and at the Omiya ward in Saitama city after 2008. These small peaks correspond to the business cores envisioned by the fourth National Capital Regional Development Plan in 1986 [9], which aimed at multi-nucleated urban structures to avoid over-concentration in the Tokyo central area. The potential over 30 years reveals how the urban structure in Tokyo has changed or remained unchanged.…”

Human flow in cities indicates social activity and can reveal urban spatial structures based on human behaviours for relevant applications. Scalar potential is a mathematical concept, and if successfully introduced, it can provide an intuitive perspective of human flow. However, the definition of such a potential to the origindestination flow matrix and determination of its plausibility remain unsolved. Here, we apply Hodge-Kodaira decomposition, in which a matrix is uniquely decomposed into a potential-driven (gradient) flow and a curl flow. We depict the potential landscapes in cities due to commuting flow and reveal how the landscapes have been changed or unchanged by years or transport methods. We then determine how well the commuting flow is described by the potential, by evaluating the percentage of the gradient component for metropolitan areas in the USA and show that the gradient component is almost 100% in several areas; in other areas, however, the curl component is dominant, indicating the importance of circular flow along triangles of places. The potential landscape provides an easy-to-use visualisation tool to show the attractive places of human flow and will aid in various applications in commerce, urban design, and epidemic spreading.

Human flow in cities indicates social activity and can reveal urban spatial structures based on human behaviours for relevant applications. Scalar potential is a mathematical concept, and if successfully introduced, it can provide an intuitive perspective of human flow. However, the definition of such a potential to the origin-destination flow matrix and determination of its plausibility remain unsolved. Here, we apply Hodge-Kodaira decomposition, in which a matrix is uniquely decomposed into a potential-driven (gradient) flow and a curl flow. We depict the potential landscapes in cities due to commuting flow and reveal how the landscapes have been changed or unchanged by years or transport methods.

Itsuki Hiroyuki’s Farewell to Moscow Misfits and Entertainment Strategies: Middlebrow Novels, Jazz Novels, and Repatriates

This paper addresses writer Itsuki Hiroyuki’s 1966 debut novel Farewell to Moscow Misfits through the lens of middlebrow novels, jazz novels, and repatriates. This novel draws from Itsuki’s personal experience being repatriated from colonial Korea after the war and visiting the Soviet Union in the mid-1960s. Farewell was unique for its time in representing jazz, music, and youth “stilyagi” counterculture in the Soviet Union. This counterculture movement was roughly contemporaneous with the student movement of the 1960s in Japan. This period also saw the popularization of the “middlebrow novel”—an ambiguous term that was used to describe literature outside of the established pure/popular dichotomy. These amorphous “middlebrow” works allow us to read some of the cultural dynamics of the 1960s. Itsuki published many of his early works in so-called middlebrow magazines, not “pure” literary journals. Itsuki himself claimed that his works were neither pure literature nor popular literature; they were simply “entertainment”. He placed his works in relation to jazz, the circus, and enka. His unique views on cultural production and media emerged from his repatriation experiences and his encounter with Russian culture. This paper examines not only genre conventions in literature but also Itsuki’s objections to the pure/popular literary structure, as well as his place in cultural representations of the 1960s.
