Partitioning chi-square for the analysis of frequency table data: an archaeological application

Archaeologists often wish to compare observed frequency distributions with expectations generated by a model. We describe a technique of partitioning chisquare which yields information about goodness of fit to a model and about homogeneity among populations simultaneously, and which is often superior to other commonly used methods of evaluating frequency data. The technique is demonstrated with data from the Upper Paleolithic rockshelter Le Flageolet I. The results suggest selective raw material use by the Aurignacian occupants.

The origin of the road and city network of Roman Pannonia

In any one macro-region there is usually one brief period of large-scale city foundation. Within Pannonia the road and city building impulse was introduced from outside along differing axial lines at three different times. Impulse chains extended from the generating points or areas to the primary objectives. The pattern of the network was determined by the selection of basic strategic objectives, which were placed on specific sites of high military-transport potentiality. Each of the road networks proved to be fanshaped composed of three elements: the axial entry route, the “cross-bar” along the Danube and “ribs” or “trusses” joining key border posts to the axis. The total pattern was that of a parallelogram of urban corridors surrounding a vacant middle.     

New Insights into the Provenance of the Obsidian Fragments of the Island of Ustica (Palermo,Sicily)

In this study we applied a multidisciplinary approach, coupling geophysical and geochemical measurements, to unveil the provenance of 170 obsidian flakes, collected on the volcanic island of Ustica (Sicily). On this island there are some prehistoric settlements dated from the Neolithic to the Middle Bronze Age. Despite not having geological outcrops of obsidian rocks, the countryside of Ustica is rich in fragments of this volcanic glass, imported from other source areas. The study of obsidian findings was carried out first through visual observations and density measurements. At least two different obsidian families have been distinguished, probably imported from Lipari and Pantelleria islands. Analysing the magnetic properties of the samples, these two main sources were confirmed, but the possibility of other provenances was inferred. Finally, we characterized the geochemical signature of the Ustica obsidians by performing microchemical analyses through electron microprobe (EMPA) and laser ablation (LA–ICP–MS). The results were compared with literature data, confirming the presence of the Lipari and Pantelleria sources (Sicily) and indicating for the first time in this part of Italy a third provenance from Palmarola island (Latium). Our results shed new light on the commercial exchanges in the peri‐Tyrrhenian area during the prehistoric age.     

Lead Isotope Analyses Revealed the Key Role of Chang'an in the Mirror Production and Distribution Network During the Han Dynasty

Chang'an (now Xi'an) was the capital of the Western Han Dynasty and the starting point of the Silk Road. In the light of the importance of Chang'an as the centre of politics, economy and cultural interaction, the overarching question proposed in this paper is focused on its role in the mirror production and distribution network during Han period. On the basis of chemical and lead isotopic analyses of 34 Han mirrors, this paper discusses the potential existence of a mirror production centre in Chang'an. Meanwhile, a comparative study with mirrors uncovered from the south‐western frontier and from Central Asian and North‐East Asian countries offers new insight into these related issues.     

Microstructural and Componential Characterization of the Plating Technology on Chinese Han Dynasty Bronze Fragments

The bronze wares of the Han Dynasty excavated in Chongqing are decorated with plating patterns, maintaining an exquisite lustre right up to modern times after the covering patina is cleared away. In this paper, a plated fragment of the Han Dynasty from the Wushan County Museum was characterized by combining optical microscopy (OM), scanning electron microscopy with X‐ray energy‐dispersive spectrometry (SEM–EDS), X‐ray fluorescence analysis (XRF), X‐ray diffraction (XRD) and X‐ray photoelectron spectroscopy (XPS). The results showed that the bronze fragment was gilded with a ~ 3 μm thick gilded layer and a ~ 20 μm thick silvered layer. The high concentration of Hg and Hg‐rich intermetallic compounds confirmed the existence of mercury gilding/silvering technology, for example, Au₉Hg in the gilded layer and Ag₁₃Hg₇ in the silvered layer. An ordered stripe structure was observed in the gilded surface, corresponding to the formation of rod‐like, intermetallic Au–Hg compounds. Specifically, a high concentration of Au was detected in the silvered layer. The exploration of gilded/silvered bronze casts light on this ancient technology and the benefit of identifying, protecting and reproducing it.     

Studies On Lacquerwares from Between the Mid‐Warring States Period and the Mid‐Western Han Dynasty Excavated in the Changsha Region

The development of lacquerwares reached its peak between the Warring States Period and the Han Dynasty (390–87 bc ) in the Changsha region of China. By studying excavated fragments of lacquers from this period, this paper examines the constitution of various pigmented layers, such as red, black and white layers, coloured lacquer layers, namely reddish brown or reddish orange, dark‐coloured or black, and silver lacquer layers, using non‐destructive methods. In addition, the characteristics of lacquer production techniques in Changsha are also discussed in comparison with those of other regions in China during the same period of time.     

ZONING A CROSS‐BORDER CITY

This paper investigates zoning in a cross‐border linear city that consists of two bordering towns. In each town, a local regulator has a say in the location of the local firm. We find that local regulators may use zoning strategically. The incentive to gain consumers from the other town, or not to lose local consumers, may push regulators to approve only locations for firms close enough to the frontier. When zoning is costly an asymmetric equilibrium may emerge: only one regulator resorts to zoning. In the case of towns of different sizes, the regulator of the larger town is the only one that zones in an asymmetric equilibrium.     

LOCATION AND ENTREPRENEURSHIP: INSIGHTS FROM A SPATIALLY‐EXPLICIT OCCUPATIONAL CHOICE MODEL WITH AN APPLICATION TO CHILE

Occupational choice and heterogeneous managerial ability enter a spatial Dixit‐Stiglitz setting, linking location, wages and regional entrepreneurship rates. Market potential has a positive partial effect and wages a negative partial effect on the regional supply of entrepreneurs, both balancing in equilibrium with endogenous wages. Market potential increases profits, but also the opportunity cost of entrepreneurship. In the long‐run equilibrium with perfect mobility, the cut‐off level of ability determining selection into entrepreneurship will be the same across regions; moreover, regional differences in entrepreneurship rates depend only in differences in average fixed costs of firms. An empirical application is provided for Chile.
