A case study of three early modern Dutch cities (Alkmaar, Delft, and Amsterdam) using geographical information systems and confronting earlier historical, sociological, and geographical models finds clear patterns of segregation below the level of the city block, thus necessitating block-face mapping. The remarkable continuity in patterns of residential segregation is best explained by the workings of the real-estate market, allowing the well-to-do and middle classes to realize their preferences. In Amsterdam, the merchant elites were able to use their political dominance to plan a scenic and expansive residential environment free from noisy and odorous activities. 相似文献

An archaeometric study was carried out on 40 gold leaf tesserae from mosaics in Italy dated 1st to the 9th century AD. Glass layers and gold leaf were both analysed by X-ray microanalysis. The main aim was the identification of the composition of the glass and of the gold leaf, in order to assess the variations in composition and nature of the tesserae in the examined period. 相似文献

The birth of the Alleanza nazionale and its rise to power in Berlusconi's 1994 and 2001 cabinets have attracted great interest. The evolution of the AN's political culture from 1995 to the present has received far less attention. The interest of scholars is dominated by concern over the number of fascist chromosomes inherited by the AN, and the way these influence its policy choices. The weight of history overlays the problems faced by the party in its attempt to establish an original identity. This article investigates the formation of the AN's political culture through an analysis of the official programmatic documents produced thus far by the party, putting each in the Italian political context at the time of its issue. The documents show that the AN is no longer a neofascist, extreme right or populist radical-right party, but its values and beliefs have not found a stable form. 相似文献

This paper focuses on the long-debated topic of the so-called calcium oxalate films: their origin and meaning but also their
age and original appearance. The restoration of the main facade of the Siena Cathedral provided a unique opportunity to this
end, thanks to the possibility of an extensive and detailed sampling and (as rarely happens) a sufficiently accurate historical
knowledge of the construction vicissitudes. This work, mainly based on a polarising microscopy study (coupled with X-ray diffraction
and SEM-EDS analyses) of over a thousand thin and ultra-thin sections of 400 microsamples, demonstrates that the current relicts
of films are the result of alteration and decay of ancient treatments. In most cases, these were linseed oil-based glazings
(the use of this substance is confirmed by historical documents) and pigments. Their role was essentially aesthetic; their
use dates the beginning of the fourteenth century and continued at least until the eighteenth century.

This article investigates the implementation of small‐scale entrepreneurship programmes in inner‐city Addis Ababa. Drawing on eighteen months of ethnographic fieldwork, it discusses the failure of these programmes to open up opportunities for social improvement for young people. It also analyses how young people confronted with this failure suggest ways of conceptualizing ‘alternatives’ to established development concepts of poverty reduction, such as microfinance and small‐scale entrepreneurship. In doing this, the author does not pretend either to offer a grand solution or to invent a brand new developmental concept. Rather, the aim is to provide a critical commentary on the reasons why some of the current academic debate on alternatives to neoliberalism have, de facto, amounted to an endorsement Ethiopia's political authoritarianism. 相似文献

Our study explores research avenues that can help policymakers to assess regional capabilities for ‘green’ economic restructuring. After reviewing the relevant literature, and envisioning research paths which consider both market transactions and externalities, we propose possible ways to translate past research findings into novel statistical tools. Our point of departure is the ‘skill relatedness’ among economic sectors in Norway, as inferred from intersectoral labour flows (years 2008–2014). Then, on the basis of the industrial composition in each of the 161 Norwegian labour market areas, candidate regions that could benefit the most from a ‘green’ restructuring policy, aimed at photovoltaics in our empirical example, are brought forward. 相似文献

The term “millets” is used to identify several genera of grasses (Poaceae), most of which belong to the subfamily Panicoideae. Millets are one of the major food sources in arid and semi-arid areas of the world and they have been important crops in the prehistory of Africa and Eurasia. In this paper, we discuss phytoliths and starch grains from two of the less studied major millets (Pennisetum glaucum and Sorghum bicolor) as well as from some small millet species that are not normally considered of much importance (so-called forgotten millets: Digitaria ciliaris, Echinochloa colona, Echinochloa frumentacea, Brachiaria ramosa, Setaria pumila and Setaria verticillata). The preliminary results of this study on phytolith morphology, both at single and joined (silica skeletons) morphotypes, and starch grains show great potentials for the identification of different genus or species on the basis of microremains. 相似文献

Several authors agree that stone surface consolidation works should not significantly alter original mechanical and hygrometric properties of the stones in order to avoid differential stress between the consolidated and non-consolidated parts. Specific limitedly destructive methodologies have been developed for assessing the variation in both mechanical and hygrometric properties, but they require preliminary calibration procedures that are very costly to adopt in terms of both time and money. This research study describes an analytical and experimental procedure aimed at obtaining the necessary hygrometric and mechanical characterization of natural and/or artificial stone, before and after consolidation works, by simply assessing the variation in the distribution of the porous structure. 相似文献
