THE NUMBER‐AVERAGE SIZE RULE: A NEW EMPIRICAL RELATIONSHIP BETWEEN INDUSTRIAL LOCATION AND CITY SIZE*

ABSTRACT The spatial intensities of both industries and population are highly uneven across space. Moreover, these intensities differ not only across industries, but also change through time. Nevertheless, we show using Japanese data for metropolitan areas in two time periods that the location intensities of both industries and population are linked by surprisingly simple and persistent patterns. In particular, we identify a strong negative log‐linear relation between the number and the average (population) size of metro areas in which a given industry is found. This relation, which we designate as the Number‐Average Size (NAS) Rule, is also shown to be intimately connected to both the Rank‐Size Rule and Christaller's (1966) Hierarchy Principle applied to metropolitan areas. In particular, we show mathematically that in the presence of the Hierarchy Principle (which holds quite well in Japan) this NAS Rule is essentially equivalent to the Rank Size Rule.     

Environmental impacts around the time of Norse landnám in the Qorlortoq valley,Eastern Settlement,Greenland

Palynology, radiocarbon dating, and open-section stratigraphies from archaeological trenches are used to examine the impact of human activity around the time of Norse landnám on vegetation and landscape associated with a small farm (Ø34) in the Qorlortoq valley, Eastern Settlement, Greenland (61° N 45° W). Peat deposits from a mire abutting the Norse ruins revealed a discontinuous palaeoenvironmental record containing a possible hiatus from ca. AD 410–1020. Palaeovegetational data were recovered either side of this period. Pollen assemblages suggest that open Salix scrub dominated the landscape during the pre-settlement phase. The later phases of landnám resulted in the creation of hay fields and heavily-grazed grassy heath. Site abandonment is reflected by a re-expansion of Salix. This occurs shortly before the onset of deposition of a Sphagnum peat, dated to cal AD 1420–1630 (2σ) and reflecting an increase in mire surface wetness, probably in response to a deteriorating climate. Radiocarbon dates were obtained on peat and plant macrofossils sampled from either side of the proposed hiatus at two different but closely-spaced (<20 m) locations across the mire. These produced significantly different dates for the cessation of peat formation in the pre-landnám period (cal BC 2130–1770 and cal AD 240–410 respectively), but near-synchronous dates for the recommencement of peat growth (cal AD 890–1150 for peat and a probably more reliable interval of cal AD 1020–1190 based on plant macrofossils). It is suggested that this hiatus may represent the first direct evidence for peat cutting in Norse Greenland.     

Spaces of Utopia and Dystopia: Landscaping the Contemporary City

Some of the most recent literature within urban studies gives the distinct impression that the contemporary city now constitutes an intensely uneven patchwork of utopian and dystopian spaces that are, to all intents and purposes, physically proximate but institutionally estranged. For instance, so–called edge cities (Garreau, 1991) have been heralded as a new Eden for the information age. Meanwhile tenderly manicured urban villages, gated estates and fashionably gentrified inner–city enclaves are all being furiously marketed as idyllic landscapes to ensure a variety of lifestyle fantasies. Such lifestyles are offered additional expression beyond the home, as renaissance sites in many downtowns afford city stakeholders the pleasurable freedoms one might ordinarily associate with urban civic life. None–the–less, strict assurances are given about how these privatized domiciliary and commercialized 'public' spaces are suitably excluded from the real and imagined threats of another fiercely hostile, dystopian environment 'out there'. This is captured in a number of (largely US) perspectives which warn of a 'fortified' or 'revanchist' urban landscape, characterized by mounting social and political unrest and pockmarked with marginal interstices: derelict industrial sites, concentrated hyperghettos, and peripheral shanty towns where the poor and the homeless are increasingly shunted. Our paper offers a review of some key debates in urban geography, planning and urban politics in order to examine this patchwork–quilt urbanism, In doing so, it seeks to uncover some of the key processes through which contemporary urban landscapes of utopia and dystopia come to exist in the way they do.
