Timber economy in the Roman Age: charcoal data from the key site of Herculaneum (Naples,Italy)

The city of Herculaneum (Naples, southern Italy), buried by the volcanic eruption of Mount Somma-Vesuvius in 79 ad, is a key site for understanding the timber economy during the Roman period. In this paper, the results of charcoal analysis of different building element types are presented. Beams, joists, poles, planks and door and window frames were investigated allowing us a view of which timber the Romans preferred for building in this area. We also fit the taxonomic results into the reconstruction of the ancient Campanian landscape, and finally, we discuss the knowledge that the Romans had about the technological properties of the wood that they used for building and the possible selection criteria that they followed in choosing them. Coniferous timber is the preferred material for building purposes. Abies alba is especially used, this fact confirming its stronger presence in southern Italian woods during the past and suggesting that its decline is mainly due to human overexploitation. The large presence of Cupressus sempervirens, selectively used for the production of poles, confirms that this tree was cultivated in plantations for timber production in the Vesuvius area. Furthermore, it might indicate that cypress could have been present as a natural tree in the local vegetation, suggesting a forest type that nowadays almost completely disappeared from this area and from the entire Italy. The findings of Juglans regia, Pinus pinea and Olea europaea, typical elements of the Mediterranean cultural landscape, show that their use was not limited to fruit production and that Romans also appreciated their timber. Beside these local resources, the presence of Picea abies and Picea/Larix indicates the importation of timber from northerly regions, probably the northern Apennines and the Alps.     

Multiproxy approach to the study of Medieval food habits in Tuscany (central Italy)

A multiproxy approach based on archaeobotanical, organic residue and isotopic analyses was carried out on materials from 12 Medieval archaeological sites in Tuscany (central Italy), in order to provide a diachronic overview of local diet in rural and urban sites from the mid-eighth to the fourteenth centuries AD. Archaeobotanical analyses were applied to 130,578 seeds/fruits, residue analyses involved 87 samples from cooking and storing vessels, whereas analyses of carbon and nitrogen stable isotopes included 63 human bone samples and 26 animal specimens. The results indicate that from the mid-eighth century AD, crop production was of high quality similar, to that of the Roman Age. The main cultivations were naked wheats, barley and horse bean, a diversity that attests the technological skills reached by Tuscan peasants during the whole Middle Ages. Different cereals and pulse abundantly supplemented the diet. This strategy not only ensured peasants’ subsistence in the mid-eighth century AD, minimizing the risks of environmental adversities, but it also increased crop production – from the mid-ninth century AD on, for the revived markets and trade. Between the eleventh and fourteenth centuries AD, C4 plants had a dominant role in the peasants’ diet, when the wheat production was strictly collected first by the landlords and then by the cities for their own needs. Crop production was integrated by swine farming; animal meat consumption is well documented in rural and urban populations from the ninth century AD. Wine and olive oil, considered important elements of diet in Medieval Tuscany, have a very scarce presence, but they are recorded for later periods, mainly in urban areas and in higher social classes, such as the religious and aristocratic ones. In fact, only between the twelfth and thirteenth centuries AD was the great expansion of olive groves and vineyards recorded, when cities and urban populations claim to have access to these luxury foods.     

Sexuality in diasporic space: rural-to-urban migrant women negotiating gender and marriage in contemporary China

Feminist geographers use the term diasporic subjectivity to emphasize the relational quality of identity as it is constructed in the dynamic in-between space occupied by the migrant and traversed by norms and practices associated with the village community, migrant peers, and urban consumer society, as well as nation-states. Using ethnographic methods, I explore how young, single rural Chinese women who migrated to Beijing in the 1990s negotiate sexuality in diasporic space, within the discursive and institutional orders of state, market and family. Though migration does not fundamentally alter these structures that construct inequality around place-based identity, gender and class, it does enable rural women to shift position within them and, significantly, to imagine that further, future change is possible. Foregrounding migrant women's agency in remaking gender identity from so-called rustic peasants to modern girls as well as in choosing marital partners and conducting courtship provides an important counterweight to the primary emphasis on structure found in much of the migration literature.     

FIRM PRODUCTIVITY AND INSTITUTIONAL QUALITY: EVIDENCE FROM ITALIAN INDUSTRY

This paper aims to contribute to the debate on the determinants of differentials in firms’ productivity. We test the hypothesis that macro factors, especially the quality of local institutions, play a central role in explaining firm productivity in Italy. To this end, we construct measures of Total Factor Productivity (TFP) for about 4,000 firms by means of different estimation techniques, and a province‐level index of institutional quality. Then, we estimate the relationship between institutional quality and firm‐level TFP. Our results show that the existence of better local institutions might help firms to become more productive.     

Seismic Assessment of the Bell Tower of Santa Maria Del Carmine: Problems and Solutions

A complete structural analysis of the bell tower of Santa Maria del Carmine in Naples (Italy) has been developed by using a 3D FE model based on the results of detailed experimental investigations in situ. Linear analysis for gravity loads, linear modal analysis, and nonlinear static analysis (Push Over) were carried out in order to assess the seismic capacity of the structure. A check of local out-of-plane failure mechanisms was also performed to verify if the structure is able to attain a global behavior. Problems and solutions related to the different methods are presented and discussed.     

Large-scale content analysis of historical newspapers in the town of Gorizia 1873–1914

We have digitised a corpus of Italian newspapers published in 1873–1914 in Gorizia, the county town of an area in the North Adriatic at the crossroad of the Latin, Slavic and Germanic civilizations, then part of the Habsburg Empire and now divided between Italy and Slovenia. This new corpus (of 47,466 pages) is analysed along with a comparable set of local Slovenian newspapers, already digitised by the Slovenian National Library. This large and multilingual effort in digital humanities reveals the statistical traces of events and ideas that shaped a remarkable place and period. The emerging picture is one of rapid cultural, social and technological transformation, and of rising national awareness, combining the larger European pattern with uniquely local aspects.     

Combining residue analysis of floors and ceramics for the study of activity areas at the Garum Shop at Pompeii

In this paper, we propose the application—for the first time in the Mediterranean area—of the combination of the study of chemical residues in floors and ceramics, with the aim of providing information about the activities carried out in archeological buildings. We chose the Garum Shop at Pompeii to test the method. In fact, due to the peculiarity of this archeological context, it provided an ideal case in which the activities performed are in part known, and the ceramic vessels recovered are still in situ. Floor samples were studied by means of spot tests developed in Mexico aimed at identifying the presence of phosphates, fatty acids, and protein residues, while the organic residues preserved in the ceramic matrix of amphorae, dolia, and other ceramic vessels were studied by gas chromatography coupled with mass spectrometry. Moreover, we integrated the data obtained with specific studies directed at better identifying the solid residues found inside two of the amphorae studied: botanical studies of fruit stones recovered in a Dressel 20 amphora and the characterization of the lime preserved in an African amphora. The research allowed for the identification of the traces of some of the activities performed, such as cooking and producing garum in the floors of the building, and the use and re-use of amphorae and dolia before the Vesuvian eruption.     

Modeling and Seismic Response Analysis of Italian Code-Conforming Single-Storey Steel Buildings

ABSTRACT

This article describes the structural design, nonlinear modeling, and seismic analysis of prototype single-storey non-residential steel buildings made of moment-resisting portal frames in the transverse direction and concentric braces in the longitudinal direction. Various design parameters (building geometry, seismic hazard, foundation soil category) and different modeling assumptions (bare frame model, model including cladding elements, ground motions including vertical accelerations, and modeling uncertainties) were considered to investigate their effects on the simulated seismic performance.     

Knowledge-Based Performance Assessment of Existing RC Buildings

One of the most challenging aspects of the seismic assessment of existing buildings is the characterization of structural modeling uncertainties. Recent codes, such as Eurocode 8, seem to synthesize the effect of structural modeling uncertainties in the so-called confidence factors that are applied to mean material property estimates. The confidence factors are classified and tabulated as a function of discrete knowledge levels acquired based on the results of specific in-situ tests and inspections. In this approach, the effect of the application of the confidence factors on structural assessment is not explicitly stated. This work presents probabilistic performance-based proposals for seismic assessments of RC buildings based on the knowledge levels. These proposals take advantage of the Bayesian framework for updating the probability distributions for structural modeling parameters based on the results of tests and inspections. As structural modeling parameters, both the mechanical material properties and also the structural detailing parameters are considered. These proposals can be categorized based both on the amount of structural analysis effort required and on the type of structural analysis performed. An efficient Bayesian method is presented which relies on simplified assumptions and employs a small sample of structural model realizations and ground motion records in order to provide an estimate of structural reliability. As an alternative proposal suitable for code implementation, the simplified approach implemented in the SAC-FEMA guidelines is adapted to existing structures by employing the efficient Bayesian method. This method takes into account the effect of both ground motion uncertainty and the structural modeling uncertainties on the global performance of the structure, in a closed-form analytical safety-checking format. These alternative proposals are demonstrated for the case study structure which is an existing RC frame. In particular, it is shown how the parameters for the safety-checking format can be estimated and tabulated as a function of knowledge level, outcome of tests, and the type of structural analysis adopted.
