Chapter 1 begins with a detailed historical account of rock radio station WLUP’s 1979 Disco Demolition Night promotion at Comiskey Stadium. The infamous event, at which baseball fans detonated a pile of disco records, was a flashpoint that presaged the codification of Chicago house music as a distinct set of cultural practices and sounds. Building on the work of urban cultural historians studying Chicago’s Black and brown cultural economies (Mumford, 1997; Heap, 2010; Green, 2007), this chapter historicizes the geographic and social frameworks that gave rise to house by showing how the demolition of musical artifacts surrogating queerness, blackness, and Latinidad sutured post-Great Migration histories of residential and economic segregation to new spaces for queer of color conviviality near Chicago’s central business district. Unlike previous accounts of the demolition (Cowie, 2010; Echols, 2010) that connect it to a national homophobic backlash against disco music, Do You Remember House? addresses the promotion as a phenomenon tied to Chicago’s particular histories of racial apartheid.

In this work, we proposed a theoretical framework inspired by physical thermodynamics to explain the housing price distributions in monocentric cities. In the same spirit as the Alonso–Muth–Mills (AMM) model, we assume that the disposable income [Formula: see text] after renting a home a distance [Formula: see text] from the center of a city is determined by the wage [Formula: see text] generated at the point-like Central Business District (CBD), the rent [Formula: see text], and the transportation cost [Formula: see text]. Unlike in the AMM model, where the scaling exponents are phenomenological, we admitted only physically reasonable exponents for the scaling of various quantities with distance [Formula: see text] from the CBD. We then determine the equilibrium rent [Formula: see text] by requiring [Formula: see text], where we assumed for simplicity the utility function [Formula: see text] (representing the demand side) has diminishing return in [Formula: see text]. In the simplest model, the equilibrium rent is given by [Formula: see text], i.e., the scaling of [Formula: see text] with [Formula: see text] is entirely determined by [Formula: see text]. We then introduce additional home availability [Formula: see text] (representing the supply side) into the simple theory in the form of an entropic correction, [Formula: see text]. The equilibrium rent then becomes [Formula: see text]. This allows us to treat additional availability due to the two-dimensional nature of cities, as well as that due to high-rise buildings on equal footing. Finally, we compare the equilibrium theory against urban data in Singapore, London and Philadelphia. For Singapore, we find quantitative agreement between theory and data. For London, we find only qualitative agreement between theory and data because the transportation cost is zone based. For Philadelphia, the home price distribution is very different from Singapore and London, and shows clear signs of economic segregation, which is difficult to treat in our equilibrium theory.

AbstractMany studies have investigated urban heat island (UHI) intensity for cities around the world, which is normally quantified as the temperature difference between urban location(s) and rural location(s). A few open questions still remain regarding the UHI, such as the spatial distribution of UHI intensity, temporal (including diurnal and seasonal) variation of UHI intensity, and the UHI formation mechanism. A dense network of atmospheric monitoring sites, known as the Oklahoma City (OKC) Micronet (OKCNET), was deployed in 2008 across the OKC metropolitan area. This study analyzes data from OKCNET in 2009 and 2010 to investigate OKC UHI at a subcity spatial scale for the first time. The UHI intensity exhibited large spatial variations over OKC. During both daytime and nighttime, the strongest UHI intensity is mostly confined around the central business district where land surface roughness is the highest in the OKC metropolitan area. These results do not support the roughness warming theory to explain the air temperature UHI in OKC. The UHI intensity of OKC increased prominently around the early evening transition (EET) and stayed at a fairly constant level throughout the night. The physical processes during the EET play a critical role in determining the nocturnal UHI intensity. The near-surface rural temperature inversion strength was a good indicator for nocturnal UHI intensity. As a consequence of the relatively weak near-surface rural inversion, the strongest nocturnal UHI in OKC was less likely to occur in summer. Other meteorological factors (e.g., wind speed and cloud) can affect the stability/depth of the nighttime boundary layer and can thus modulate nocturnal UHI intensity.
