Questioning Polycentric Development and its Effects. Issues of Definition and Measurement for the Italian NUTS-2 Regions

Polycentric development is a widely used term both in academic research and in the normative agenda. However, its theoretical foundations and economic implications are still unclear and the concept of polycentricity still does not have a shared definition or a shared measurement method. The aim of this study is two-fold. First, it defines and measures polycentricity at a NUTS-2 regional level, by comparing functional and morphological methods. Second, in the light of the role assigned to polycentric development in terms of policy, the study investigates the relationships between the degree of regional polycentricity and the key economic variables of performance, namely, competitiveness, social cohesion and environmental sustainability. Our main finding was that functional and morphological methods lead to similar results. In addition, we find a correlation between polycentricity and a more unequal income distribution and a higher level of productivity, especially when polycentricity was measured in functional terms. No stable correlations were found between polycentricity and measures of environmental sustainability, such as land consumption and greenhouse gas emissions.     

Floor Response Spectra for Bare and Infilled Reinforced Concrete Frames

The objective of this article is to study the effects of structural nonlinear behavior on Floor Response Spectra (FRS) of existing reinforced concrete frames. This study examines how the FRS vary with the level of post-elastic behavior in buildings of different number of stories and masonry infill wall configurations. The effect of damping modeling assumptions is also investigated. Differences and similarities with findings from the literature are discussed. On the basis of the obtained results, a commentary on the adequacy of basic assumptions used in predictive equations proposed by different seismic codes is offered.     

Susceptibility measurements,optical and X-ray analysis to explain the origin of archaeological magnetic anomalies in Tavoliere lowland (Southern Italy)

Since 2002 a non-invasive investigation integrating aerial photography and high-resolution magnetometry has been carried out for reconstructing extensive ancient settlements in Tavoliere lowland (Southern Italy). Relevant magnetic anomalies were detected in all the surveyed sites allowing a precise mapping of the buried structures over more than 150 ha. Next to this research susceptibility measurements, PXRD, XRF and optical analysis were also performed in order to explain the origin of the notable magnetization contrast between the anthropogenic structures and the embedding materials, generating the measured signals. This last study was accomplished, in 2006, in Monte S. Vincenzo site, a vast Neolithic village where the remotely sensed data were also used to guide some direct inspection. Trial archaeological excavations brought to light parts of C-shaped compounds, providing complete information on the geometry and location of the sources of magnetic signals. Profiting by the archaeological feedback, the susceptibility contrast between the soil filling the ditches and the calcareous substratum was assessed in situ. A synthetic model based on this information was created and compared with the experimental data. The infilling material was also sampled for laboratory analysis: the presence of several magnetic minerals (pyroxenes, monometric magnetite, haematite) was ascertained. Furthermore optical analyses showed different types of volcanic and igneous products such as pumices, melanite garnets and lava fragments. Geomorphological and archaeometric evidence allowed us to relate these materials to activity of the Mt. Vesuvius volcano. Eventually their possible spatial distribution was inferred from recent studies on ash transportation and deposition during explosive activity.     

Seeing the churches like the state: taxes and wealth redistribution in late antique Italy

Two key economic questions tend to be asked about the transformation of the Roman world. First, how did Roman fiscal structures continue, disintegrate and transform? Second, how did emerging churches play a role in the redistribution of wealth through new administrative structures to create a new social system, what Ian Wood has called a ‘temple society’? These two processes – one focussing on the continuity or discontinuity of the Roman economic structures and the other on churches within that system – are usually examined separately or assumed to follow, what we call here, a ‘Gallic model’. In this article, we first demonstrate that Wood’s ‘temple society’ is far more complex in its emergence in Italy than in Gaul. Second, we argue that the churches of Italy remained embedded within late Roman fiscal structures, even as they transformed during late antiquity. Fiscal arrangements, examined through the churches of Rome and Ravenna, established churches as ever more central economic actors to the state fiscal system by 600 and shaped their long-term wealth redistribution process.     

Microscope observations and DNA analysis of wine residues from Roman amphorae found in Ukraine and from bottles of recent Tuscan wines

Morphological analysis by light and electron microscopy was conducted on wine residues from second century Roman amphorae found in Myrmekion (Ukraine). The results of the archaeological samples were compared with residues formed in bottles of wine from Tuscan vineyards, corked between 1969 and 1977 without filtration and enzyme or biochemical processing. Staining and histochemical observation of the archaeological and recent residues detected nucleic acids. Molecular analysis was also performed using nuclear microsatellite SSRs markers having high polymorphism to study genetic relationships. Genotype profiles of archaeological and recent residues were compared with contemporary cultivars in a data bank. Low homology of genotype profiles of all residues, and oral evidence, confirmed the presence of autochthonous varieties in recent wines and enabled indirect assessment of varieties detected in the archaeological material. The results confirmed that the archaeological material could be related to Sangiovese and indicated Roman wine trade as far afield as Ukraine, whereas the recent residues provided evidence of disappearing native Tuscany cultivars like Gorgottesco, Mammolo, Verdello, Rossone and Tenerone, used for table wines until the late seventies.     

Reconstructing Kilmainham: the topography and architecture of the chief priory of the Knights Hospitaller in Ireland,c.1170–1349

ABSTRACT

For almost 400 years the Knights of St John of Jerusalem – the Knights Hospitaller – maintained a priory in Kilmainham, Co. Dublin, as their principal residence in Ireland. Nothing survives of it above ground. The priory's early history and topography are mainly shrouded in mystery, but a fourteenth-century registrum illuminates the workings of its community and the character of its members, and provides valuable evidence relating to the appearance of its architecture and layout when it was at the peak of its prosperity. Yet the registrum has never been subjected to detailed scrutiny. Recent research on the Hospitallers in Ireland on the one hand, and on the organisation of domestic space in medieval contexts in Ireland on the other, has prompted this comprehensive appraisal of the evidence in Kilmainham's registrum.
