CD ROM imaging in osteoarchaeology

This paper describes the potential use of CD ROM in osteoarchaeology. It describes what CD ROM is and how it works, how CD ROM disks are produced and how the technique could be used in osteoarchaeology. The hardware required, both to produce and access compact disks, is outlined together with approximate costs. The possible uses of the technique in osteoarchaeology are suggested. Costs for the hardware are reasonable. However, collaboration between organizations will be essential.     

Constructing a Manufacturing Fixed Capital Stock Series for the Regions of Greece

Although regional variation in rates of capital accumulation is considered a major component of spatially uneven industrial development, it remains largely an understudied area. The theoretical and methodological problems that surround the measurement of capital, generally, alongside the lack of necessary information about a wide range of specific aspects, pose serious obstacles in any attempt to construct regional capital stock series. In such a context, the main aim of this paper is to make the best possible effort to construct a regional manufacturing fixed capital stock series for Greece. The limited availability of information (not unusual in regional as opposed to national contexts) and the necessity of making some arbitrary, but specified, assumptions mean that the estimation steps have to be presented in detail to assess reliability. Four regional fixed capital stock series for total manufacturing activity are generated. The results are then assessed in the context of uneven spatial development in Greece.

Approximating the Length of Vehicle Routing Problem Solutions Using Complementary Spatial Information

Accurately estimating the length of Vehicle Routing Problem (VRP) distances can inform transportation planning in a wide variety of delivery and service provision contexts. This study extends the work of previous research where multiple linear regression models were used to estimate the average distance of VRP solutions with various customer demands and capacity constraints. This research expands on that approach in two ways: first, the point patterns used in estimation have a wider range of customer clustering or dispersion values as measured by the Average Nearest Neighbor Index (ANNI) as opposed to just using a Poisson or random point process; second, the tour coefficient adjusted by this complementary spatial information is shown to exhibit statistically more accurate estimations. To generate a full range of ANNI values, point patterns were simulated using a Poisson process, a Matern clustering process, and a simple sequential inhibition process to obtain random, clustered, and dispersed point patterns, respectively. The coefficients of independent variables in the models were used to explain how the spatial distributions of customers influence the VRP distances. These results demonstrate that complementary spatial data can be used to improve operational results, a concept that could be applied more broadly.
