Analysis of polychrome Iron Age glass vessels from Mediterranean I,II and III groups by LA-ICP-MS

In this work the analytical results obtained by ICP-MS with laser ablation solid sampling and SEM-EDS for some polychrome glass vessels from the Iron Age are presented and discussed. The samples, coming from Etruscan sites near Adria (Northern Italy), belong to the so-called Mediterranean Groups I, II and III and are dated from the 5th, 3rd and 2nd century B.C., respectively. To date, analytical data for only two sets of vessels of the Iron Age have been discussed in the literature. In spite of the low number of available samples, this is the first time that vessels of all three periods are analytically compared. Elemental concentration data show that the samples can be classified as low-magnesia-low potash (LMLK) soda-lime-silica glasses, with low phosphorus and titanium contents, in agreement with data for similar samples of the same age. Bivariate and multivariate analyses of the contents of many elements characterizing the siliceous sands showed three distinct sets corresponding to the three periods. Since the sets indicate different provenances of the sands it seems rational to assume that different glassmaking locations were involved. Chromophores and opacifiers of the blue bodies and the yellow, white and turquoise decorations of the vessels were analytically identified, while the nature of the corresponding ores was hypothesized.     

THE BORDER POPULATION EFFECTS OF EU INTEGRATION*

ABSTRACT Border cities or regions are in theory more affected by the EU integration process than more central locations as it more drastically influences their transaction costs and market potential. We find a positive empirical effect of EU enlargement as measured by the growth in population share along the integration borders. This effect is active for a limited distance (70 km) and time period (30 years), and is more important for large cities and regions. Despite this positive EU enlargement effect along the border, a location close to a border remains a burden in view of the (larger) negative general border effect.     

REGIONAL POPULATION–EMPLOYMENT DYNAMICS ACROSS DIFFERENT SECTORS OF THE ECONOMY*

ABSTRACT An important subset of the literature on agglomeration externalities hypothesizes that intrasectoral and intersectoral relations are endogenously determined in models of local and regional economic growth. Remarkably, structural adjustment models describing the spatio‐temporal dynamics of population and employment levels or growth traditionally do not include intersectoral economic dynamics. This paper argues and shows that allowing for economic linkages across sectors in these models adds considerable value, especially in forecasting. An econometric model of population–employment dynamics, in which sectoral variations in economic development are explicitly taken into account, is applied to a large urban planning policy proposal in the Netherlands. The empirical analyses suggest that population dynamics are largely exogenous, population changes drive employment in particular in the industry and retail sectors, and employment in all sectors depends strongly on intersectoral dynamics. Intersectoral dynamics appear as important drivers of regional sectoral employment changes; they are even more important than population changes, and their effect shows up clearly even within the Dutch institutional context where strict regulatory housing and planning restrictions are enforced.     

Navigational Equipment from 't Vliegend Hart (1735)

The Dutch United East-India Company ship 't Vliegend Hart sank in the mouth of the River Scheldt in 1735. With archival sources the wreck was located in 1979, and in the following years researched and excavated, a process still continuing. This article gives a brief historical introduction on the ship, followed by a paragraph on the art of navigation and navigational instruments at the time of 't Vliegend Hart 's sailing. Thereafter this is compared with the navigational artefacts retrieved from the wreck. In the final paragraph the exploration of the 't Vliegend Hart wreck is briefly dealt with.

Johann Gaspar Spurzheim: The St. Paul of phrenology

ABSTRACT

Franz Joseph Gall’s wayward discipline Johann Gaspar Spurzheim greatly modified Gall’s original system and introduced it to the English-speaking world. Through an active program of itinerant lecturing, publishing and converting disciplines, Spurzheim made phrenology. He also developed a philosophy of following the laws of nature that was adopted and further promoted by his disciple, George Combe. Combe’s book The Constitution of Man (1828) became one of the best-selling works of its genre in the nineteenth century. Thus Spurzheim, never particularly original, exercised an enormous influence on nineteenth-century culture.     

NEIGHBOURHOOD ETHNIC MIX AND THE FORMATION OF MIXED‐ETHNIC UNIONS IN BRITAIN: A LONGITUDINAL ANALYSIS

Although developed societies are becoming increasingly ethnically diverse, relatively little research has been conducted on geographies of mixed‐ethnic unions (married or cohabiting). There is some recent evidence from the US that mixed‐ethnic couples are more likely to be found in mixed‐ethnic neighbourhoods, but this research is based on cross‐sectional data. Therefore it is not possible to determine whether mixed‐ethnic couples are more likely to form in mixed‐ethnic neighbourhoods or whether they are more likely to move there. Our longitudinal analysis allows us to tease out the relative importance of these two processes, furthering our understanding of the formation of mixed‐ethnic unions. Using data from the Office for National Statistics Longitudinal Study we examine neighbourhood effects on the formation of mixed‐ethnic unions in England and Wales. We find that mixed‐ethnic unions are more likely to form in neighbourhoods with low concentrations of co‐ethnic population. The results from this study lend support to the contact theory that geographical proximity to other ethnic groups enhances mutual understanding between people from different ethnic groups and could lead to the development of intimate partnerships.
