    494 pages : illustrations (some color), maps (some color) ; 26 cm. Conference sponsored by the American Museum of Natural History and the St. Catherines Island Foundation.Although this volume covers a broad range of temporal and methodological topics, the chapters are unified by a geographic focus on the archaeology of the Georgia Bight. The various research projects span multiple time periods (including Archaic, Woodland, Mississippian, and contact periods) and many incorporate specialized analyses (such as petrographic point counting, shallow geophysics, and so forth). The 26 contributors conducting this cutting-edge work represent the full spectrum of the archaeological community, including museum, academic, student, and contract archaeologists. Despite the diversity in professional and theoretical backgrounds, temporal periods examined, and methodological approaches pursued, the volume is unified by four distinct, yet interrelated, themes. Contributions in Part I discuss a range of analytical approaches for understanding time, exchange, and site layout. Chapters in Part II model coastal landscapes from both environmental and social perspectives. The third section addresses site-specific studies of late prehistoric architecture and village layout throughout the Georgia Bight. Part IV presents new and ongoing research into the Spanish mission period of this area. These papers were initially presented and discussed at the Sixth Caldwell Conference, cosponsored by the American Museum of Natural History and the St. Catherines Island Foundation, held on St. Catherines Island, Georgia, May 20-22, 2011.

    Proposing new measures of employment deconcentration and spatial dispersion across metropolitan areas in the US

    A well-known challenge is measuring employment concentration across metropolitan areas and analysing the evolving spatial structure. We introduce a new approach that avoids identifying “job centres” and conceptualizes the distribution of employment based on two dimensions: (1) employment deconcentration; and (2) spatial dispersion of high employment locations. We apply this framework to study 329 US metropolitan regions based on 1 sq km. grid cells. We find diverse trajectories of metropolitan restructuring between 2000 and 2010, and substantial variation across regions in employment concentration. The new framework enables researchers to compare metropolitan regions to gain insights into the dynamic nature of metropolitan spatial structure

    Testing the Monocentric Urban Model: Evidence Based on Wasteful Commuting

    No full text
    Recent papers have questioned the ability of the monocentric urban model to account for urban development patterns. Most damaging are estimates of wasteful commuting that indicate actual commuting may be eight times as large as efficient commuting predicted by the strong form of the monocentric model. This study recomputes previous estimates of wasteful commuting in a monocentric city that relaxes the strong form assumption that all households are identical. The recomputed estimates indicate that actual commuting is only twice as large as efficient commuting, a result generally consistent with the monocentric model.
