Interpolating geochemical patterning of activity zones at Late Neolithic and Early Copper Age settlements in eastern Hungary

The Late Neolithic of southeast Hungary is known almost exclusively from excavations of large settlement mounds, or tells. Geochemical analyses of sediments collected from boreholes at small, flat Late Neolithic and Early Copper Age settlements in Hungary's Körös River basin provide data necessary to interpret the spatial organization of small settlements for the first time in this region. Principal Components Analysis of multi-element data produced a workable number of variables. Spatial analyses of these components via interpolation in ArcGIS 9 identified specific task areas, and when combined with sediment characterizations, phosphate ‘spot-tests’ and pH, suggest long-term cultural traditions in the location of activity zones within small farmsteads. The results demonstrate the usefulness of multi-element geochemistry as an intra-site prospection method.     

Urban-rural demographic contrasts in Highland Ecuador: town recession in a period of catastrophe 1778–1841

An investigation of three Andean towns in their regional setting forms the basis for an assessment of urban-rural demographic differences. The towns are found to have been ethnically distinct, with a larger proportion of whites than the mainly Indian rural areas. The urban populations also had a larger surplus of women, lower average marriage ages for women but lower proportions married, a higher illegitimacy rate and a slightly older age structure. Trends in urban districts differed from those in rural areas. The towns suffered major population losses, and their share of the regional population fell from nearly 10% in 1778 to around 5% in 1841. The factors affecting population trends are examined in order to identify those which had a differential urban-rural impact. Earthquake and warfare were of key significance. In a regional context of economic depression and population stagnation, these two catastrophes instigated a major urban recession. The three towns shared in the urban decline experienced in many parts of Latin America, but their recession was particularly pronounced owing to the impact of catastrophes.     

A STRUCTURAL EMPIRICAL ANALYSIS OF METROPOLITAN LABOR DEMAND*

ABSTRACT. This paper uses a large data base to study metropolitan labor demand functions. The data are disaggregated by two-digit SICs in manufacturing for SMS As, and are corrected for changing SMSA boundaries. Labor demand elasticities are estimated for factor and commodity prices, transportation costs, state and local taxes and expenditures, and production-function shifters. Estimates from different years allow one to test Le Chatelier's principle in the context of interregional change.     

Mapping population data from zone centroid locations

The author describes the difficulties associated with the use of maps to represent census data. "A review of the problems associated with population mapping is followed by a discussion of [an alternative method known as] a raster method for handling census data, based on population-weighted centroids, and its implications for GIS "[geographic information systems]." The geographical scope is worldwide, with an example provided using data for Wales.
