PROBLEMS OF PASSENGER MOBILITY AND ROAD TRANSPORT IN THE SOUTHERN FAR EAST REGION

Dimensions of the road transport problem in the southern Far East Economic Region (Primorskiy Kray, Amur Oblast, and Khabarovsk Kray) are outlined and some of its social and economic impacts described (for example, the inadequate levels of services provision addressed in the preceding paper). Road connectivity and passenger mobility trends are analyzed before coverage shifts to more specific challenges confronting planners: the need to (a) separate inter-city from intra-city flows in cities along major transport corridors, (b) improve road surfaces, (c) reduce travel times and regulate seasonal fluctuations in service, and (d) provide a more favorable environment for growing private automobile use (translated by H. L. Haslett, Leamington Spa, UK).     

AN ARCHAEOMAGNETIC STUDY OF POTTERY KILNS FROM BRÜHL-PINGSDORF (GERMANY)*

Four pottery kilns from Brühl-Pingsdorf (Germany) were dated by comparing their characteristic remanent magnetization with a curve of the palaeo-secular variation of the geomagnetic field. Archaeomagnetic results suggest last heating events between AD 775 and 1020. The archaeological evidence generally supports the relative temporal succession and the duration of use, but indicates that the kilns are about 150 years younger on average. Hence, a systematic offset between these independently developed chronologies must be considered. Rock magnetic parameters display radial variations through the kiln walls. These variations are controlled by the maximum temperature the rock was exposed to. These parameters were used to identify specimen which acquired a thermoremanent magnetization.     

COMPACTNESS AND ELECTORAL BOUNDARY ADJUSTMENT: AN ASSESSMENT OF ALTERNATIVE MEASURES

Spatial compactness has been proposed as a suitable criterion for assessing whether electoral boundaries reflect partisan interests. Although several different measures of spatial compactness have been developed, only limited efforts have been made to compare and evaluate them in the context of electoral redistricting. This paper assesses alternative spatial compactness measures and applies conceptually appealing measures to the provincial ridings proposed by British Columbia's Royal Commission on Electoral Boundaries (1988).     

SAND FOR ROMAN GLASS PRODUCTION: AN EXPERIMENTAL AND PHILOLOGICAL STUDY ON SOURCE OF SUPPLY*

This paper reports the results of an experimental study performed on Campanian littoral sand, together with a careful philological analysis of Pliny's text concerning the production of glass using the above sand in order to verify its suitability. Accurate chemical and mineralogical characterization of sand samples and experimental glasses was carried out, proving the unsuitability of sand for glass production in its original state. Taking into account both the results of the philological analysis of Pliny's text and the mineralogical assemblage of the sand, a new hypothesis regarding Roman glass‐making technology is proposed and tested here. The technology implies the production of ‘quartz‐enriched’ sand by means of selective grindings according to the different degrees of hardness and cleavage of the mineralogical phases. Melting experiments, carried out on treated sand and in the temperature range compatible with Roman technology, yielded a glass with composition similar to those of typical Roman glasses. Therefore, new perspectives on the sources of supply of raw materials, hitherto debated, are opened up.     

AN EARLY CELTIC POTTERY WORKSHOP IN NORTH WESTERN HUNGARY: SOME ARCHAEOLOGICAL AND TECHNOLOGICAL EVIDENCE

Summary. Excavations at the settlement site of Krautacker in the outskirts of Sopron (NW Hungary) have produced evidence of pottery manufacture from LT B to LT C. Three kilns of updraught type were discovered. Their technology is discussed. Stamp-decorated wheel-turned ware was produced throughout. The contexts and distribution of these vessels are considered.     

NEW COMPETITION IN SHOPPING-CENTER HIERARCHIES: AN EMPIRICAL COMPARISON OF ALTERNATIVE SPECIFICATIONS*

ABSTRACT. Within the framework of an existing hierarchy of shopping centers, Voronoi diagrams at each level of the hierarchy are used to define infringement on existing centers by new entrants. We distinguish four intensities of infringement—that is, four categorizations of when existing centers face new competition—and label shopping centers accordingly. Our aim is to determine empirically which type of new competition is best explained by various attributes of the incumbent centers. To accomplish this, logit analysis is used to relate the above labels to market-area population, store turnover, age, and hierarchical level of each shopping center in Edmonton, Alberta.     

CAMPANIAN POTTERY FROM ANCIENT BRUTTIUM (SOUTHERN ITALY): SCIENTIFIC ANALYSIS OF LOCAL AND IMPORTED PRODUCTS*

One hundred and fifty-seven sherds of Campanian pottery were analysed by inductively coupled plasma optical emission spectroscopy (ICP-OES) and flame emission spectroscopy (FES). The sherds were found in the course of archaeological excavations carried out at the sites of Sibari, Cosenza, Crotone, Locri, Reggio and Oppido Mamertina in southern Italy (ancient Bruttium, today Calabria). Analyses were carried out on dissolved samples, determining 15 elements per sample (Al, Fe, Ca, Mg, Ti, Mn, Sr, Ba, Cr, Cu, Y, La and Sc by ICP-OES, and Na and K by FES). Analytical data were subject to multivariate statistical treatment by hierarchical cluster analysis and principal components analysis. Results indicated different compositional groups, allowing one to separate suspected imports from Campania, Etruria and Sicily from each other and from likely local products. The latter could be further classified into different groups, comprising imitations of foreign forms as well as original local products.

THERMOLUMINESCENT DATING OF NEOLITHIC AND CHALCOLITHIC POTTERY FROM SITES IN CENTRAL PORTUGAL

Samples of Neolithic and Chalcolithic pottery from nine sites in the Upper Alentejo and Estremadura regions of Portugal have been dated by the thermoluminescence method (quartz inclusion technique). The project was designed to help establish an absolute chronology for the Neolithic and Chalcolithic periods in this area, and to try to elucidate the chronological relationships between settlement sites and burial sites (‘dolmens’) in the same area. Portugal was confirmed, together with Brittany, as being one of the earliest foci of megalith builders.     

SOUTH APPALACHIAN MISSISSIPPIAN AND PROTOHISTORIC MORTUARY PRACTICES IN SOUTHWESTERN NORTH CAROLINA

Abstract

Mississippian societies of southwestern North Carolina are generally thought to have been less centralized and less hierarchical than their counterparts elsewhere in the Southeast. This paper compares and contrasts mortuary patterns at the Warren Wilson, Garden Creek, and Coweeta Creek sites to reconstruct patterns of social and spatial differentiation within late prehistoric and protohistoric communities in southwestern North Carolina. These sites include, respectively, a late prehistoric stockaded village, a platform mound and village, and a protohistoric Cherokee town with a public structure and several domestic dwellings. Distributions of burial goods and the placement of burials indicate that some social distinctions were reflected in the treatment of the dead by Mississippian and protohistoric groups in southwestern North Carolina, and that those distinctions were embedded in the architecture and built environment of these sites.     

传统藏陶传承千年再焕新生

Traditional Tibetan pottery has a long history and comes in varying categories and shapes,making it one of ethnic Tibetans’ most refined forms of cultural art.Today,however,very few craftsmen have been able to fully pass on the pottery-making process,and pottery makers have disappeared from the map entirely in some places.     

THERMOLUMINESCENCE DATING OF POTTERY: AN ASSESSMENT OF THE DOSE-RATE FROM RUBIDIUM

The naturally occurring radioisotope ⁸⁷Rb makes a small contribution to the total dose-rate. Assuming an average potassium:rubidium ratio of 200:1 the contribution is estimated at 2.9% of the B dose-rate From potassium. The effect will be negligible in quartz inclusion dating because of the strong attenuation of the B- emission from ⁸⁷Rb. In fine-grain dating the omission of the ⁸⁷Rb contribution will overestimate the age of a pottery sherd by not more than 2% and this is regarded as of minor importance when the total error in the technique is at least 15%.     

中原地区史前陶窑发展演变研究

陶器是新石器时代的广域性文化遗存之一,明显改变了史前人类包括饮食结构在内的诸多生活方式,并促进了史前文化的繁荣与发展,因而制陶术也被视为史前人类的重大发明之一.以往对制陶技术的研究多集中在制坯成型工艺方面,陶窑结构虽也被纳入考察的范畴,却未能充分考虑烧制技术与陶窑结构之间的内在联系,似乎一直没有把握住陶窑形态结构演变的核心特征.中原地区(本文主要指河南及山西中南部)不仅是新石器时代文化发展的重要区域,也发现有裴李岗文化以来各个阶段的史前陶窑遗存,为探讨史前陶窑的结构演变及烧制技术提供了较系统的实物依据.本文在充分考虑烧制技术的基础上,通过陶窑形态结构分类,力求把握其结构演变的核心特征及演变规律.
