Theoretical and Numerical Seismic Analysis of Masonry Building Aggregates: Case Studies in San Pio Delle Camere (L’Aquila,Italy)

Masonry building aggregates are large parts of the Italian building heritage often designed without respecting seismic criteria. The current seismic Italian code does not foresee a clear calculation method to predict their static nonlinear behavior. For this reason, in this article a simple methodology to forecast the masonry aggregate seismic response has been set up. The implemented procedure has been calibrated on the results of two FEM structural analysis programs used to investigate three masonry building compounds. As a result, a design chart used to correctly predict the base shear of aggregate masonry units starting from code provisions has been set up.     

“A Chronicle of a Death Foretold”: Urban Expansion and Land Consumption in Rome,Italy

The article analyses the long-term changes in the spatial distribution and density of the urban settlements in Rome (Italy), a compact Mediterranean city recently undergoing low- and medium-density expansion. Eight density classes were considered: no buildings, <0.5 buildings per hectare, 0.5–1.0, 1–2, 2–3, 3–5, 5–10, >10 buildings per hectare. Non-urbanized land amounted to 89% of the investigated area in 1919 and fell to 30% in 2001. Building density increased over time suggesting that both concentration and diffusion processes occurred in the study area. During 1919–2001, the building density was stable in only 37% of the investigated land. In that period, the largest part of the area (47%) underwent a low increase in building density, while 12% of the area passed from a low-density to a high-density class. Settlement density decreased rapidly with the distance from the city centre in 1919 and 1945, while a marked increase was observed in areas progressively further away from Rome since 1961. In recent years, land consumption was partly determined by the planning strategies adopted by Rome's municipality with the aim of producing a more balanced and polycentric region. More effective policies preserving the quality of the environment and promoting the sustainable development of peri-urban Mediterranean regions are needed.     

Early agriculture and palaeoenvironmental history in the North of the Iberian Peninsula: a multi-proxy analysis of the Monte Areo mire (Asturias,Spain)

A multi-proxy study (pollen and NPPs, geochemical composition and radiocarbon dating), combined with principal components analysis, was applied to a core sampled in the Monte Areo mire (Asturias, N Spain), which covers the last 11,600 years cal BP. Both signals of Holocene climate change and transformations by human activities were recorded.     

Characterization of elemental and firing-dependent properties of Phlegrean ceramics by non-destructive ED-XRF and NMR techniques

A combination of energy dispersive X-ray fluorescence (ED-XRF) and 2D proton nuclear magnetic resonance (¹H NMR) relaxometry was employed for the characterization of two groups of similar ceramic fragments from the high-medieval production of the Phlegrean area (Miseno and Cuma, Southern Italy). Both methods are based on the use of non-destructive and portable instruments. This approach allows to correlate complementary microstructural features of ceramics, both dependent and independent of the firing technique.     

Medieval phases of settlement at Benabbio castle,Apennine mountains,Italy: evidence from Ground Penetrating Radar survey

The lack of written sources for many of the medieval castles in the northern Apennines (Italy) makes it difficult to completely establish the most ancient historical phases of these settlements. The church of San Michele belongs to an abandoned fortified settlement of the Castle of Benabbio, in the mountains surrounding Lucca. Thanks to an epigraph still visible on the façade, the church foundation is dated back to AD 1218. However, several archaeological findings at the settlement seem to suggest stages of encastlement that are older than the church foundation.     

Xing: The Discourse of Sex and Human Nature in Modern China

In Modern Chinese, xing is the character most commonly used to denote sex, gender and sexuality. However, the character was a specialist Confucian term originally meaning ‘human nature’ in Classical Chinese, and only came to signify both sex and human nature in the early twentieth century. This usage was invented by Japanese intellectuals in the late nineteenth century for their translations of sexological texts from Europe, in which they encountered the concept of sex as a natural drive and the fundamental core of individuals. This article investigates the convoluted linguistic career of xing, and argues that in China in the 1920s, sex/xing became the point of anchorage for a new politics, which naturalised sex, legitimised talk about reproduction and desire, and made imperative the intensification of the production of scientific knowledge on sex (and by extension ‘human nature’). It is emphasised that the history of xing in China in the 1920s is not just a curiosity or appendage to more ‘mainstream’ history of sexuality; rather, it is impossible to appreciate the global nature of modernity without a thorough understanding of the circulation of sexual ideas.     

Multi-technique characterization of dyes in ancient Kaitag textiles from Caucasus

Kaitag textiles, named after the Kaitag district of Southwest Daghestan, Russia, where it is being manufactured, are a unique embroidered textile art form. They were used by families on special occasions such as the birth, marriage or death of one of their members and were thus passed down from generation to generation as family heirlooms. Today, only a few hundred of these precious antique specimens can still be found, and surviving examples are mostly from the seventeenth and eighteenth centuries. In this article, an extensive work for the scientific analysis of Kaitag textiles is presented as the logical continuance and updating of the investigations performed by thin layer chromatography almost two decades ago. A multi-technique approach involving the combined use of micro-invasive and nondestructive techniques suitable for in situ analyses was used, aiming to identify the colourants of Kaitag textiles and the inks employed for the underlying drawing. Analyses were performed by high-performance liquid chromatography, surface-enhanced Raman spectroscopy, scanning electron microscopy combined with energy dispersive X-ray analysis, as well as visible reflectance spectroscopy and X-ray fluorescence. In addition, infrared reflectography and ultraviolet fluorescence were employed to visualise underlying drawings and possible restorations. Corrosion phenomena observed in brown- and black-dyed areas were also investigated.     

Post-Tensioned Glulam Beam-Column Joints with Advanced Damping Systems: Testing and Numerical Analysis

This article describes tests investigating a feasible source of passive damping for post-tensioned glue-laminated (glulam) timber structures. This innovative structural system adapts precast concrete PRESSS technology [Priestley et al., 1999] to engineered wood products combining the use of post-tensioned tendons with large timber members. Current testing is aimed at further improvement of the system through additional energy dissipation. Testing has favorably compared glue-laminated timber (not previously implemented in this way) with laminated veneer lumber (LVL) used in New Zealand. After initial benchmark testing with post-tensioning only, a simple, minimally invasive and replaceable type of hysteretic damper was added.     

Understanding cultural heritage in Turkey: institutional context and organisational Issues

This paper explores Turkey’s cultural heritage system from the perspective of the ‘Heritage Chain’, which sees the heritage sector as an interconnected series of relationships and activities including protection and conservation, archaeological activity, research and museum presentation. By reviewing quantitative data along each step of the chain, we construct a holistic perspective that shows interrelationships between activities and illustrates which parts of the system are underdeveloped. By demonstrating the effects of Turkey’s distinct combination of bureaucratic fragmentation and centralisation on professional practice among conservators, archaeologists and museums, we argue for increased attention to administrative issues within heritage studies.
