CHARACTERIZATION OF PLASTERS AND MORTARS AS A TOOL IN ARCHAEOLOGICAL STUDIES: THE CASE OF LARDIRAGO CASTLE IN PAVIA,NORTHERN ITALY*

Plasters and mortars from Lardirago Castle (Pavia, northern Italy) have been characterized by means of petrographical and chemical analyses in order to achieve technical and historical evidence of material production. The study focused on the oldest nucleus of the structure, where hidden plastered masonry has been discovered recently. Textural and compositional data of the binder and the aggregate fractions were collected by means of optical microscopy and electron microscopy coupled with microanalysis. These data permit the identification of building materials with similar technical and compositional characteristics, which can be related to different building phases.     

A THERMAL METHOD FOR ARCHAEOLOGICAL PROSPECTION: PRELIMINARY INVESTIGATIONS

Interaction of archaeological features with the secular variation in surface heat flux generates an anomalous ground temperature distribution which can form the basis for a shallow geophysical prospecting tool. Earlier studies have concentrated on recording surface temperature disturbances via aerial thermography but these results can be biased towards minor variations in vegetation, albedo. and microclimate. A more promising approach is to record temperatures at a depth of 20cm using a simple probe. Anomalies at this depth arise from the interaction of objects with the annual heat-flux cycle and other long-term temperature variations. The amplitude, shape, and phase of anomalies have been modelled, together with the nature and magnitude of other, unwanted causes of ground temperature variation. Field equipment and data processing techniques for the direct-contact approach to thermal prospection have undergone trails in the U.K. at Verulamium and Fountains Abbey.     

A NEW METHOD FOR EXTRACTION,ISOLATION AND TRANSESTERIFICATION OF FREE FATTY ACIDS FROM ARCHAEOLOGICAL POTTERY

This paper presents evidence for increased recovery of organic residues from archaeological pottery through use of a microwave‐assisted liquid chromatography protocol. C_16:0 and C_18:0 saturated fatty acids were obtained from archaeological potsherds recovered from nine Neolithic settlements in the Middle East dating between 4700 and 7300 cal bc , including materials that had not produced evidence for the survival of any lipid species through use of ‘conventional’ solvent extraction techniques. Compound‐specific isotopic analyses of C_16:0 and C_18:0 fatty acids in potsherd extracts subsequently revealed δ¹³C/δ¹²C compositions consistent with modern subcutaneous fats of wild boar and goats pastured on lands adjacent to the Jordan Valley, and residues from a modern pottery vessel used in the manufacturing of butter, cheese and yogurt in central Turkey. These results are presented as an illustration of capabilities of the microwave‐assisted recovery protocol. The reclamation of saturated and unsaturated fatty acids from archaeological pottery fragments recovered from a number of the earliest ceramic horizons in the Middle East is herewith reported, and the extraction methods and instrumental analytical techniques are described.     

ORTHOIMAGE‐BASED DOCUMENTATION OF ARCHAEOLOGICAL STRUCTURES: THE CASE OF A MEDIAEVAL WALL IN PONTEVEDRA,SPAIN

During the completion of the expansion works at the Museum of Pontevedra (Spain), a stretch of about 60 m of the medieval walled enclosure surrounding the historic city centre was discovered. Due to its value as a heritage element, the discovery of this archaeological structure required the implementation of preservation activities and exhaustive documentation so that future generations will be able to know and enjoy this piece of history. This paper presents digital models that reproduce the original structure of the wall using close‐range digital photogrammetry, as well as orthophotos, which thoroughly document the dimensional and textural characteristics of the archaeological site. In addition to analysing the accuracy and validity of photogrammetry in the conservation of archaeological heritage, a methodology of data capture, processing and photogrammetry representation is evaluated.     

条件价值法评估旅游资源游憩价值的效度检验——以杭州西湖风景名胜区为例

运用条件价值法评估资源的经济价值,假想市场的构建使得评估的信度和效度备受质疑。早在20年前,发达国家关于条件价值法的相关研究已从实施实验、报告内容和结果,向检验结果的信度和效度方向转变。国内旅游资源研究的相关领域,对条件价值法信度和效度的关注非常罕见。文章以杭州西湖风景名胜区为个案,运用条件价值法进行游憩价值评估,并进一步聚焦评估效度的深入探讨。条件价值法的评估结果表明:杭州西湖风景名胜区2012年的游憩价值为7.14亿元。效度检验结果表明:杭州西湖风景名胜区的意愿调查具有良好的内容效度;与运用旅行费用区间分析法的评估结果566.04亿元相比,两者并不具备良好的收敛效度,前者的评估结果明显偏低;建构效度检验说明杭州西湖风景名胜区的意愿调查结果部分可以从经济学角度得到解释。     

"LOCAL" DEVELOPMENT IN SOUTHERN EUROPE: TOWARDS A NEW MYTHOLOGY

From the mid-1970s onwards, many southern European regions experienced a pattern of decentralized development and growth. This pattern has been largely explained by theories of “local” or “endogenous” development which became the new catch-phrases during a period of great financial difficulties. Despite logical improvements and the use of some radical rhetoric, local development approaches based on rationalization of existing cases (especially in Third Italian regions) suffer both in their theory and practice from the same inherent limitations of two decades ago. The paper argues for an alternative interpretation of local development characteristics in Portugal, Spain, Italy and Greece, discussing the political implications of proposed policies.     

ARCHAEOSEISMOLOGY IN ITALY: CASE STUDIES AND IMPLICATIONS ON LONG-TERM SEISMICITY

Four Italian cases from central Apennines and central-eastern Alps show how the use of archaeoseismology and paleoseismological investigations on deformed archaeological remains may improve the knowledge on long-term seismicity. In the Fucino Plain (central Apennines), the displacement of a Roman canal (built during the lst-2nd century AD) was caused by the movement of one of the active faults affecting the basin. The paleoseismological analysis and available archaeological data permitted to date the event at the 5th-6th century AD and to hypothesise that this earthquake was also responsible for significant damage to the Colosseum in Rome shortly before 508 AD. At the Egna site (Bolzano province, northern Italy), the displacement of a Roman building has been paleoseismologically investigated. It probably resulted from surface faulting, thus permitting to hypothesise the occurrence of strong earthquakes in an area for which seismicity does not show significant historical earthquakes. In the Sulmona Plain (central Apennines) the occurrence of a strong event around the middle of the 2nd century AD is testified by ah epigraph. Widespread evidence of building, collapses and abandonments characterise a number of archaeologically investigated sites and confirm the age of occurrence inferred from the epigraph. In the Trento area (northern Italy), evidence of earthquake-induced damage to medieval buildings suggests that the earthquake which affected northern Italy in 1117 may have been responsible for significant damage also in the Adige Valley. Gained experience indicates that in areas where historical research does not contribute significantly to the knowledge of the effects of strong earthquakes, the use of archaeological evidence of past earthquakes may be a valuable tool to obtain information on the historical seismicity related to moderate-large magnitude events.

国家空间选择性、新城新区的开发及其房地产化——以南京河西新城为例

本文认为有必要将中国城市新区开发运动理解为新区空间快速开发与城市空间不平衡发展的相统一过程。本文引入国家空间选择性理论视角来理解中国城市新区开发的"双统一"过程。首先,将国家空间选择性理论具体化为三个分析维度——选择性的空间发展战略、选择性的国家权力和国有资源空间配置。进而以南京河西新城为例,从国家空间选择性角度实证解析了其发展的"双统一"过程。主要结论是：国家的空间选择性给河西新城的开发配置了明显优于其他地区的战略、权力和国有资源条件,引导社会资本的集中涌入,塑造了不平衡发展的城市格局。国家空间选择性主导的发展模式一定程度上引致了河西新城发展的房地产化。     

A NEW DATING METHOD FOR HIGH‐CALCIUM ARCHAEOLOGICAL GLASSES BASED UPON SURFACE‐WATER DIFFUSION: PRELIMINARY CALIBRATIONS AND PROCEDURES*

The first European settlers came to North America in the early 17th century using glass in the form of containers and decorative objects. Thus, glass is a horizon marker for all historic period settlements and a potential source of chronometric dates at archaeological sites belonging to the historic period in the Americas. We have developed a new absolute dating method based upon water diffusion into the surface of manufactured glasses that predicts diffusion coefficients based upon variation in glass chemical constituents. Low‐temperature (< 190°C) hydration experiments have been performed on a set of five high‐calcium (21.7–28.3%) glasses that were used to manufacture wine bottles from the 17th?19th centuries. Infrared spectroscopy and secondary ion mass spectrometry was used to model the water diffusion/alkali exchange process. The ability of the model to accurately predict archaeological ages was evaluated with artefacts recovered from ceramic‐dated contexts at Thomas Jefferson's plantation known as Monticello.

NON‐DESTRUCTIVE ANALYTIC METHOD USING XRF FOR DETERMINATION OF PROVENANCE OF ARCHAEOLOGICAL OBSIDIANS FROM THE MEDITERRANEAN AREA: A COMPARISON WITH TRADITIONAL XRF METHODS*

A non‐destructive analytical method using wavelength‐dispersive X‐ray fluorescence (WDXRF) that allows the establishment of the provenance of archaeological obsidians was developed and a comparison with the classical XRF method on powders is discussed. Representative obsidian samples of all the geological outcrops of archaeological interest of the Mediterranean area (Lipari, Pantelleria, Sardinia, Palmarola and the Greek islands of Melos and Gyali), were analysed with the normal procedures used in rock analysis by XRF (crushing, powdering and pelletizing). The non‐destructive XRF analysis was instead conducted on splinters taken from the original geological pieces, with the shape deliberately worked to be similar to the refuse usually found at archaeological sites. Since the analysis was conducted on the raw geological fragment, intensity ratios of the suitably selected chemical elements were used, instead of their absolute concentrations, to avoid surface effects due to the irregular shape. The comparison between concentration ratios (obtained by traditional XRF methods) and the intensity ratios of the selected trace elements (obtained from the non‐destructive methodology) show that the different domains of the chemical composition, corresponding to the geological obsidians of the source areas, are perfectly equivalent. In the same way, together with the geological splinters, complete archaeological obsidians, from Neolithic sites, may be analysed and their provenance may be determined. The proposed non‐destructive method uses the XRF method. Due to its sensitivity, low cost and high speed, it is surely an extremely valid instrument for the attribution of the provenance of the archaeological obsidian from Neolithic sites.
