Seismic Vulnerability of Building Contents for a Given Occupancy Due to Multiple Failure Modes

A methodology is presented for assessing the seismic vulnerability of inventories of contents to multiple failure modes. An ordering method to find out probabilities of failure of a conditional mode upon the survival of the other modes is applied. The procedure considers the statistical correlation of failure modes due to the dynamic response, such as sliding and/or overturning, of contents and also to non structural components. This methodology was applied to inventories of four types of occupancy (house, school, office, and hospital) located in Mexico City, considering that all contents are situated at ground level. Expected damage functions for these inventories show large differences between them, the house and school inventories being the least vulnerable, and the hospital inventory, the most vulnerable, even for low intensities.     

An inventory of abandoned mining exploration sites in Nunavik,Canada1

This article presents, for the first time in the literature, an inventory of abandoned mining exploration sites in Nunavik, namely the sites containing materials representing a danger to the environment and human health, to lay the foundations for a priority cleanup operation. In this article, the historical context of mining exploration in Canada first provides a backdrop for the research problem. The methodology section then examines the various techniques tested during a pilot project aimed at determining the feasibility of the project at the lowest cost. The final section presents an inventory of abandoned sites and begins an initial discussion of the potential impacts associated with these sites and some of the priority actions envisioned to mitigate these impacts.     

Earth Sciences Comparative Matrix: A Comparative Method for Geoheritage Assessment

Geological heritage is insufficiently recognised in Australia; it should be considered in its own right, not as an addendum to other heritage values. The lack of a suitable robust and repeatable methodology has seriously constrained the assessment of geological sites suitable for the National Heritage List (NHL). A desktop assessment of Australian desert landscapes required intrinsic natural values of a diverse group of sites, spread over a vast area, to be assessed against NHL criteria. The Earth Sciences Comparative Matrix (ESCoM) was developed for this study. In the ESCoM, sites are grouped in process themes. Each is assessed against NHL criteria then compared with other similar places, according to degree of unusualness, integrity, and authenticity. A site scoring well across multiple themes has increased heritage significance. The overall values of a site are quantified, leading to a qualitative judgement on whether it achieves the threshold of outstanding heritage value. Examples of assessment using this method are given. In this methodology, significance determination is based on rigorous comparisons of specific values. It is semi‐quantitative, repeatable, and robust. It differs from other geoheritage assessment methods in its combination of process‐based groupings (facilitating the separation of site type from heritage criteria), matrix structure (minimising complexities of scale or diversity), and use of numerical rankings as an aid in decision‐making. While the study for which ESCoM was developed was focused on landforms, it can be used for other types of geoheritage (e.g. fossils, tectonic processes), with modification of matrix theme headings.     

Rocking of Non-symmetric Rigid Blocks in Buildings Considering Effects Associated with Dynamic Soil-Structure Interaction

A dynamic model for the estimation of the rocking and/or overturning response of a free-standing non-symmetric rigid block considering rotational and horizontal excitation is proposed. The block is situated at different levels of a building with flexible base subjected to earthquakes. Base flexibility introduces the rotational component of the excitation due to dynamic soil-structure interaction (DSSI). The model is used to assess the influence of the dynamic soil-structure interaction on the behavior of the block. An illustrative example of the proposed model for non-symmetric rigid blocks in 5-, 10-, and 15-story buildings located in soft soils considering earthquakes from different seismic sources is presented. Results show that it is important to consider kinematic effects as well as inertial effects of DSSI in the dynamic response of contents. The influence of base flexibility depends on the change of spectral intensities associated to the increase of the building structural period and is larger for higher building levels.     

The resources and economy of Scotland re‐viewed

The increasing demand for sand and gravel in Scotland is examined and it is shown that most reserves occur in areas of fluvioglacial deposition. Against this background, existing methods of evaluation are compared and it is argued that these techniques are either too costly and time‐consuming, or else not of general applicability to all regions containing aggregate supplies. A new methodology is suggested which overcomes these drawbacks and provides a means by which a trained geomorphologist can produce a reasonably accurate inventory of reserves in a given region. An example of the application of this new procedure to North East Scotland is considered.     

Methodological problems in the analysis of fossil non-artifactual wood assemblages from archaeological sites

The analysis of fossil wood fragments is often undertaken in relation to the archaeological excavation of a site. However, such analysis does not yet appear to have the strong methodological foundation that the investigation of many other classes of palaeoenvironmental evidence (e.g. seeds and pollen) have. Consequently, it is difficult to evaluate the value of fossil wood analysis at an archaeological site. Using data regarding non-artifactual wood assemblages at one site in southern Scotland, the relative merits of possible analysis are described and discussed. The results from such analyses tend to fall into two broad groups: (I) those of relatively high reliability, and (2) those of relatively low reliability. The results in the former group are often based on moderately secure methodology and tend to provide relatively non-interpretative information (e.g. species lists). On the other hand, those in the latter group are more often based on insecure interpretive methodology and provide relatively more stimulating information, such as evidence for prehistoric woodland management. There are many reasons for this situation, and these are discussed. In conclusion, it is argued that to increase the reliability of results in the second group (in particular), a full understanding of the taphonomy of non-artifactual fossil wood assemblages is needed, and that once this is available attention can then be paid, as elsewhere in environmental archaeology, to the problems of providing statistically valid samples for analysis.     

METALLURGICAL ANALYSIS FROM SARAZM,TADJIKISTAN SSR

Recent excavations of the Bronze Age site of Sarazm (35W2000 B.C., uncalibrated) were undertaken by a collaborative team of archaeologists from the U.S.S.R. and U.S.A. The site is located in the Zeraoshan Valley in Tadjikistan SSR. A series of radiocarbon dates are presented as well as the analysis of 8 metallurgical samples. This Bronze Age site represents the easternmost extension in central Asia of an urban community with a rich metallurgical inventory.     

Petrographic Characterization and Provenance Determination of the Crystalline Marbles Used in the Roman City of Banasa (Morocco): New Data on the Import of Iberian Marble in Roman North Africa

This paper reports the results of an archaeometric study of the crystalline marbles used in the Roman city of Banasa (Morocco). On‐site surveys allowed a detailed inspection of the monuments of the ancient city and sampling of the different marble lithotypes used for architectural purposes and sculptures. The inventory was completed by the study of both the grey‐and‐white streaked or spotted marble items stored in the warehouse of the archaeological site and of those currently exhibited at the National Archaeological Museum of Rabat. Provenance determination of 28 samples was carried out by means of a multi‐method approach combining mineralogical–petrographic data and C–O stable isotope analyses as the first step, and cathodoluminescence microscopy as a complementary technique to verify possible unusual alternative origins of some marbles. The analytical results obtained were compared with both the most reliable international databases and the few available studies dealing with the use of marble in other Roman towns in Morocco (e.g., Volubilis, Thamusida and Sala‐Chellah). They point to a variety of classical marble sources such as Carrara, Mount Penteli, Paros, Marmara and probably Mount Filfila (Algeria), and prove a significant import of Iberian lithotypes.     

Hazor rulership and ritual manipulation

ABSTRACT

Hazor was unquestionably the largest Bronze Age Canaanite site, standing as an anomaly in the southern Levant in terms of its size, elaborate public architecture, special geopolitical stature and far-reaching international networks. While the site has been well established as an urban center with many temples, the use of each of Hazor’s temples and how they relate to one another remains unclear. In this study, we analyze the rituals and other activities that were conducted within Hazor’s numerous temples. The methodology we employ stresses, fundamentally, the necessity to contextualize objects within entire assemblages – through spatial analysis – to most accurately assess how Hazor’s cultic spaces were actually used. We apply the same methodology to other MB and LB Canaanite temples to establish a generalized ideal-type temple assemblage for Canaanite temples. This study successfully demonstrates that Hazor’s temples substantially diverge from the ideal temple assemblage, indicating cult at Hazor was practiced differently than elsewhere in the region. This includes the atypical distribution of certain cultic vessels (e.g. miniature vessels), the appearance of special vessels in ritual contexts (e.g. cups), and a fundamentally different use of indoor and outdoor spaces when compared to other Canaanite temples. It turns out that Hazor’s elites were major factors controlling the anomalies of cultic practice at the site. Hazor’s rulers impacted cultic architectural forms and locations and played instrumental roles in dictating and manipulating the types of rituals and associated cultic paraphernalia that were allowed to be performed and used throughout the entire settlement landscape.     

Collagen fingerprinting of archaeological bone and teeth remains from Domuztepe,South Eastern Turkey

We applied a recently developed method of collagen peptide mass fingerprinting for taxonomic identification in faunal remains to 111 specimens from the Neolithic site of Domuztepe in southeastern Turkey. Advances on the published technique allow us to move beyond the key domesticated fauna (sheep, goat, pig and cattle) to include non-domesticates (deer and gazelle, as well as humans). As the animal economy of Domuztepe was dominated by domestic sheep and goats, a large number of the samples tested were morphologically indistinguishable sheep/goat remains. A number of samples represented elements that provide information on age (i.e., mandibles) or sex (pelvis); thus, this represents the first major study to attempt to improve kill-off profiles using collagen fingerprinting. We also show that the collagen extracted from dentine is equally amenable to the proposed methodology as bone collagen.     

Context, curation, and bias: an evaluation of the Middle Paleolithic collections of Combe-Grenal (France)

The site of Combe-Grenal is arguably the reference site for the Mousterian of southwest France. Bordes excavated the site over a period of 13 years and generated a large collection of lithics and fauna from a deep series of 64 Lower and Middle Paleolithic levels. Though Bordes only partially published his work at the site, its long stratigraphic sequence and particularly its collections have been subjected to numerous studies over the years and have figured prominently in several long-running debates concerning the Mousterian. Recently, the authors undertook a project to inventory and analyzed these collections along with the documentation of their archaeological context. In so doing, however, a number of serious problems became apparent with the collection in its current state, problems that cannot easily be resolved given the state of the available documentation. These problems have important implications not only for results of studies based on these collections, but more generally, they also point to problems in terms of how archaeological collections are curated.     

Three-dimensional (3D) visualisation: the application of terrestrial laser scanning in the investigation of historical Scottish farming townships

Recent developments in digital technologies are heralding significant changes in the way we acquire, visualise and analyse archaeological data. Terrestrial laser scanners can be used to create photo-realistic virtual copies of landscapes, and archaeological features, and offer the potential to improve our understanding of three-dimensional (3D) spatial relationships at study sites. Here we present a methodology for the integration of a high-resolution 3D site model with soil chemical data obtained from an abandoned settlement site located in the Central Highlands of Scotland. At this site, the multi-element concentration in soil, co-visualised within a topographic setting, has an important role to play in elucidating settlement layout and activity. The methods described here are also of significance in archiving sites of archaeological/historical importance where development activities and/or environmental processes may destroy remains, or where access to field sites is restricted.     

Evidence of behaviour from refitting‐a case study

A re‐examination of the lithic remains from the preboreal site of R?rmyr II by means of the method of refitting has shown that the site represents the remains from a single occupation. In this article the authors focus on various behavioural aspects recognized within three contemporaneous activity areas on the site. Furthermore, the idiosyncratic knapping characteristics of the people who produced the material will be discussed. By distinguishing between the various types of refits represented, in addition to examining the implications of the typological inventory, the site of R?rmyr II has been characterized as a short‐term hunter's camp‐site, and not as a specialized hunting station.     

SEISMIC HAZARD ASSESSMENT IN FLORENCE CITY ITALY

A seismic hazard analysis of Florence city was performed in the frame of a project concerning the dynamic behaviour of cable-stayed bridges. Both a probabilistic approach and a methodology based on the use of a local macroseismic catalogue were applied. A local catalogue was expressly compiled for this purpose, to collect the macroseismic intensities actually observed at the site as a result of past earthquakes. This sort of catalogue is an independent tool to verify the assumptions of the probabilistic approach (seismic zoning, earthquake recurrence relation, attenuation model), though it can supply results in terms of macroseismic intensity only and reflects the effective seismic history at the site, without taking into account any variability. The Cornell' methodology was used to assess probabilistic hazard in terms of macroseismic intensity, peak ground acceleration, peak ground velocity, and pseudovelocity uniform response spectra. The local catalogue points out level VII of the Mercalli-Cancani-Sieberg scale (MCS) as the maximum intensity historically observed in Florence. The probabilistic approach leads to the consideration of intensity VIII MCS as the maximum credible for the city. The probabilistic analysis in terms of ground motion was performed using attenuation relations estimated for alluvium sites, since the geology of Florence area is represented by fluvial and lacustrine deposits of various thickness. Peak ground acceleration values with 90% non exceedence probability in 50 and 500 years are respectively 145 and 219 cm/s's for a shallow alluvium site, and 95 and 157 cm/s's for a deep alluvium site; the corresponding peak ground velocity values for sites located on alluvium are 6.41 and 11.76 cm/s. Uniform response spectra are provided for shallow and deep alluvium sites, according to frequency-dependent attenuation relations estimated from strong Italian earthquakes.     

A SPATIO‐TEMPORAL KERNEL METHOD FOR MAPPING CHANGES IN PREHISTORIC LAND‐USE PATTERNS

Archaeologists are accustomed to considering both the spatial distributions of sites and the temporal distributions of dates as means of analysing the dynamics of prehistoric societies. However, spatial and temporal approaches have thus far remained largely separate, rather than being combined within a single, unified framework. A formal methodology is outlined that combines univariate kernel density estimation based on radiocarbon dates with bivariate kernel density estimation based on spatial site coordinates; the approach allows archaeologists to arrive at reconstructed land‐use distributions through time that not only correct for the problematic issue of site contemporaneity, but also reflect the continuous nature of the archaeological record. The model is implemented using as a data set a series of sites from the Mesolithic of Atlantic Iberia; the results demonstrate that it is capable of providing key insights into changing patterns of land use that are not apparent from either the temporal or the spatial perspective alone.     

Archaeological Heritage Management at the Memphis and its Necropolis World Heritage Site

This research explores archaeological heritage management at the Memphis and its Necropolis – the Pyramid Fields from Giza to Dahshur World Heritage Site in Egypt. The case study methodology involved a structured questionnaire in order to gather data from key stakeholders. The results suggest only partial implementation of the World Heritage Site (WHS) management plan due in part to financial constraints, while strategies to raise visitor numbers remain limited. Actions are required to promote tourism, and to find resources for site enhancements. Current site management responsibilities appear centralised, with a need to develop an integrated management plan for the WHS. There could be better understanding of the needs of visitors and how these can be met. The study recommends development of a more Integrated Management Plan for the site, perhaps also involving some restructuring of key (state) organisations and/or specifically the creation of an entity responsible for management of the site.     

Bedding, hearths, and site maintenance in the Middle Stone Age of Sibudu Cave, KwaZulu-Natal, South Africa

Micromorphological analysis of sediments from the Middle Stone Age site of Sibudu Cave, KwaZulu-Natal, South Africa, provides a high-resolution sequence and evidence of site formation processes of predominantly anthropogenic deposits. This methodology allows for a detailed interpretation of individual anthropogenic activities, including the construction of hearths and bedding and the maintenance of occupational surfaces through the sweep out of hearths and the repeated burning of bedding. This analysis also provides a context for evaluating other studies at the site relating to magnetic susceptibility, paleobotany, paleozoology, anthracology, and studies of ochre.     

Clues to Stone Tool Function Re-examined: Comparing Starch Grain Frequencies on Used and Unused Obsidian Artefacts

The identification of plant residues observed on prehistoric stone artefacts has often been used to inform on tool function without adequate consideration of potential contamination due to post-depositional processes. The paper redresses this balance by proposing a methodology which combines use-wear and residue analyses with systematic testing of depositional context to distinguish residues formed during tool use from accidental contamination. A case study involving obsidian artefacts from an open site in Papua New Guinea is used to illustrate the new approach. Starch grains, a class of residue which has had little attention outside Australia, were chosen as the focus of study because of their abundance at this site. The frequency of starch grains extracted from residues on stone artefacts was compared with those in sediments adhering to and adjacent to the artefact. A use-wear study conducted as a blind test provided an independent measure of whether the artefacts had been used. The frequency of starch grains was shown to be significantly correlated with used artefacts and not correlated with unused artefacts or the sediments. The case study demonstrates the importance of testing for contamination and also illustrates the benefit of studying starch grains as a class of plant residue.     

Putting the Spotlight on Small Metal Age Pottery Scatters in Northern Calabria (Italy)

This paper presents the results of an in-depth multidisciplinary restudy of small Metal Age surface scatters recorded in earlier fieldwalking surveys in northern Calabria (Italy). Guided by a stratified sampling approach based on site types and topographic positions, high-resolution surface collections at the selected sites were combined with geophysical surveys, test pits, and soil studies to investigate both archaeological deposits and the site formation processes that have an effect on their detectability. This approach is shown to result in a better definition of archaeological ‘sites’, and to help fill in details of regional exploitation and settlement dynamics at the landscape scale. At this broader scale we are also able to model post-depositional processes and slope dynamics affecting the preservation of the archaeological record. With regard to methodology, our study has enabled the evaluation of diverse archaeological detection methods and the fine-tuning of field strategies for the study of Metal Age remains.
