Koan amphorae from Halasarna – investigations in a Hellenistic amphora production centre

Ceramic amphorae have been the most popular transport and storage containers for a large variety of liquid and solid products. The amphorae of the present study were used as transport containers for wine from the island of Kos (East Aegean). Therefore, they had to fulfil certain requirements in terms of mechanical strength and toughness but also in terms of standardization of vessel size and shape. An assemblage of amphora fragments from the excavation of ancient Halasarna, an amphora production centre, will be presented. The ceramics were studied by means of their chemical and mineralogical composition and fabric. Furthermore, their material properties were measured and their mechanical performance was simulated in computer models.     

Keeping an eye on your pots: the provenance of Neolithic ceramics from the Cave of the Cyclops,Youra, Greece

Combined petrographic and chemical analysis of MN and LN ceramics from the Cave of the Cyclops on the island of Youra, Greece, has revealed a compositionally diverse assemblage with a range of different local and off-island sources. Ceramics deposited in Neolithic times on this barren, rocky outpost of the Sporades chain may have originated from a surprising number of possible origins, including from the Plain of Thessaly, Euboea and the volcanic northeast Aegean islands. This picture challenges traditional assumptions about Neolithic pottery production and indicates that significant movement of ceramics was already taking place within the northern Aegean as early as the beginning of the sixth millennium BC. The discovery of a persistent local pottery tradition, that is also found on the neighbouring island of Kyra-Panagia, indicates significant continuity in ceramic technology over some 1500 years.     

Urbanization and Socioeconomic Status in the European Regions: The Role of Population Ageing and Capital City Regions

Using the European Community Household Panel data survey and confirmatory factor analysis, this paper explores the causal relationship between the multidimensional concepts of urbanization and socioeconomic status in the European Union. It shows that income, education and occupation are strongly related to status, and the density of population area and the town size, to urbanization. The relationship between urbanization and status is positive. This means that urban areas contain the residences of the elite, such as the rich, those with high levels of educational attainment and people with high-calibre jobs. This paper does not provide evidence to support the idea that individuals lose socioeconomic status as they age and that status is higher in capital city regions. The relationship between urbanization and status is relatively stronger for the old working-age cohort and for the non-capital city regions. These results have policy implications with regard to social welfare and urban and regional planning and development.     

INTEGRATION OF IMMIGRANTS,BRIDGING SOCIAL CAPITAL,ETHNICITY, AND LOCALITY

This paper analyses a uniquely detailed data set of social integration characteristics of immigrants belonging to four non‐native ethnic groups (i.e., Turks, Moroccans, Surinamese, and Antilleans) living in Dutch neighborhoods. It is well known that an individual's level of social integration is related to the ethnic composition and economic development of an immigrant's residential locality, as well as the generation of the immigrant. Yet, what is not known is whether the social and economic characteristics of adjacent or neighboring localities also influence an individual's level of social integration. Using a multilevel hierarchical analysis with spatial interaction effects, we examine the extent to which four social integration aspects of the bridging social capital of these immigrant groups are related to their ethnicity, their generation, their immediate locality, and the effects of the neighboring localities. Our findings regarding the effects of the ethnic concentration and economic development of the immediate locality along with the immigrant's generation broadly concur with existing studies. At the same time, however, we also find that the features of neighboring localities exert an additional influence on an individual's social integration over and above those related to the immigrant's generation and immediate locality. These additional spatial spillover effects are broadly in line with those associated with the immediate locality, but they are also sensitive to particular proxies for social integration which are employed. These spatial spillover effects on social capital and social integration have not been observed before.     

High-temperature performance of two-layered ceramics and the implications for Roman crucibles

Roman metalworking crucibles are frequently characterized by an extra outer layer of clay, applied to a pre-formed vessel. Three-point bending and standardized dead-weight loading tests were conducted to determine the advantages offered by the extra outer layer. Deformation and fracture behaviour, at temperatures up to 1100°C, of two-layer, monolithic and tempered-monolithic briquettes were compared. Measurements indicated that the two-layer briquettes were more resistant to fracture at high temperatures: > 850°C they showed more extensive plastically deformed regions than monolithic briquettes. The influence of temper was consistent with previous results: tempering caused quasi-stable fracture and reduced fracture strength. The results suggest extra outer layers assisted in preventing catastrophic failure.     

EDUCATION AND INCOME INEQUALITY IN THE REGIONS OF THE EUROPEAN UNION*

ABSTRACT This paper provides an empirical study of the determinants of income inequality across regions of the EU. Using the European Community Household Panel dataset for 102 regions over the period 1995–2000, it analyses how microeconomic changes in human capital distribution affect income inequality for the population as a whole and for normally working people. The different static and dynamic panel data analyses conducted reveal that the relationship between income per capita and income inequality, as well as between a good human capital endowment and income inequality is positive. High levels of inequality in educational attainment are also associated with higher income inequality. The above results are robust to changes in the definition of income distribution and may be interpreted as a sign of the responsiveness of the EU labor market to differences in qualifications and skills. Other results indicate that population ageing, female participation in the labor force, urbanization, agriculture, and industry are negatively associated to income inequality, while unemployment and the presence of a strong financial sector positively affect inequality. Finally, income inequality is lower in social‐democratic welfare states, in Protestant areas, and in regions with Nordic family structures.     

Mirages and miracles of European small and medium enterprise development

A small‐scale industry ‘renaissance’ has characterized recent academic literature on industrialization and development policies. This comes as a reaction to the manifest difficulties facing mass production economies and to the sometimes spectacular performance of small‐ and medium‐sized enterprises (SMEs), particularly in Europe. The causes of the above success, together with the accompanying theorizations — such as the flexible specialization approach — are manifold and contradictory. Furthermore, theories on the present and future of SMEs vary as regards both optimism and policy implications — supra‐national, national or regional. Recent EU policies towards SMEs present an amalgam of instruments which, albeit often economically effective, constitute chiefly a political gesture.     

Nonlinear Static and Dynamic Behavior of a 16-Story Torsionally Sensitive Building Designed According to Eurocodes

A 16-story building under construction in Bucharest has been designed according to the provisions of EC2 and EC8, using elastic spectral modal analysis. Considering that the building is torsionally sensitive in the nonlinear range, it was further checked and verified using nonlinear dynamic and static procedures, using a detailed space-frame model. Specifically, time-history analysis for seven different excitations, as well as respective inelastic static analysis taking into account torsional effects were performed. The results are examined regarding structural (global) and member (local) response and various issues concerning the adequacy of the original elastic design and the applicability of advanced analysis methods are discussed.     

A Saxon Fish Weir and Undated Fish Trap Frames Near Ashlett Creek,Hampshire, UK: Static Structures on a Dynamic Foreshore

The remains of a wooden V-shaped fish weir and associated structures have been discovered near Ashlett Creek on the tidal mudflats of Southampton Water in Hampshire, southern Britain. Radiocarbon dating of oak roundwood stakes taken from the main weir structure date it to the middle Saxon period. Clusters of as-yet undated roundwood posts within the catchment area of the weir are interpreted as the frames for fish traps that are assumed to pre- or post-date the operational period of the weir itself. The weir is contemporary with wooden V-shaped fish weirs found elsewhere in southern and central Britain, and also Ireland, but its circular catchment ‘pound’ remains restricted, in these islands, to the Solent and Severn estuaries: it has a close parallel with another Saxon-era weir on the nearby Isle of Wight. It also shows striking structural similarities with examples in use today in Basse Normandy, on the southern shore of the English Channel. The paper discusses the function and operation of the weir, and places it in its social and historical context. Regressive cartography demonstrates that the structures have become exposed as a result of saltmarsh retreat in this area of Southampton Water since the nineteenth century. The radiocarbon dates returned for the posts demonstrate that this transgression of the marsh must have been preceded by a prolonged period of progradation, which covered and preserved the site; its subsequent re-exposure has negative implications for its survival.     

Mind the Gaps: The Evolution of Regional Earnings Inequalities in the U.K., 1982–1997

In this paper we apply earnings equations for U.K. regions over 1982–1997. We find evidence of rapid convergence across regions regarding the determinants of individual wages (i.e., regional fixed-effects, gender gaps, and returns to education and experience). In contrast, data on average regional earnings point to a worsening of U.K. regional inequalities and a rise in the North-South gap. Education accounts for most of the discrepancy between aggregate divergence and disaggregated convergence. First, London gained because its workforce became relatively more educated over the period. Second, returns to education increased nationwide, which favored the most educated regions (i.e., London). Third, returns to education were initially lower in London but they (partially) caught up with the rest of the country. Had returns to education and their distribution across U.K. regions remained stable over the period, the U.K. North-South divide would have decreased.
