Assessment of the Lines of Torres Vedras defensive system with visibility analysis

A method to assess the coherence of defensive systems based on the individual and combined visual coverage of fortifications is presented. The case study is the complex fortification system of Lines of Torres Vedras, around Lisbon, Portugal, activated in the first decade of the 19th century to halt the French armies of Napoleon in the Peninsular War. As messages between fortifications are known to have been exchanged visually by semaphore, GIS-based viewshed calculations enabled the assessment of the system's coherence and the exploration of how the undocumented communication with the defensive forces' headquarters in Lisbon might have been achieved. Results show that the defensive system with its two lines was highly effective per se with respect to the visual coverage of the terrain and the exchange of messages between fortifications, but it could have been improved with minor changes to the location of communication devices. It is also found that communication with the headquarters in Lisbon was not adequate, suggesting that additional devices were needed.     

Investigation of past archaeological landscapes using remote sensing and GIS: a multi-method case study from Mount Ida,Crete

Spatial analysis in geoarchaeological applications can be improved by implementing a wider set of geoecological parameters, in order to provide more precise results. The aim of the paper is to show how geoscientific ground-truth and techniques can be adopted for detailed archaeological studies using a comprehensive set of environmental variables that might have influenced ancient settlement patterns. The project focuses on spatial patterns of archaeological sites as well as Bronze Age communication paths in Central Crete by applying a multi-method approach (surveying, remote sensing, DEM analysis, least-cost analysis, candidate site detection, predictive modelling, etc.). In contrast to conventional archaeological GIS applications this enhanced strategy offers promising prospects regarding landscape and settlement modelling.     

The visibility of past trees and woodland: testing the value of insect remains

The reconstruction of woodland history is important in relation to archaeological, ecological, biogeographical and evolutionary problems, and insect remains are a significant source of relevant information. Fully natural interglacial and Holocene ‘waterlogged’ deposits assumed to have formed in woodland generally contain abundant macrofossils of both plants and insects indicative of trees. In contrast, British archaeological deposits rich in macrofossil remains of trees often lack, or contain very few, tree-associated insects. To cast light on this contradiction, assemblages of insect (Coleoptera and Hemiptera) remains from a range of modern deposits with various spatial relationships to woodland and trees have been analysed. The proportions of tree-associated insects varied greatly. There was a general trend from higher values in woodland and near to isolated trees of species supporting a rich insect fauna, to low or zero values where there were no trees. However, low values sometimes occurred in woods or near trees, so that rarity of tree-associated insects in archaeological deposits does not always carry the implication of a treeless environment. Further investigation is suggested, with emphasis on the importance of identifying isolated trees, scrub and hedges as a resource for humans and wildlife in the past.     

Enhancing the mobility of collections and access to cultural heritage: immunity of cultural objects from seizure in Poland

This paper analyses, from the perspective of cultural policy considerations, the legal regime established by the recent Polish law on the immunity from seizure of cultural property on loan (2015). It deals with current trends of international museum exchange and explains the benefits and risks involved in cross-border loans of cultural material. This analysis is carried out by focusing on the actual practice and experiences of Polish museums, national and international regulations in force, and human rights considerations. The authors attempt to situate the Polish model for the protection of foreign cultural property on loan within the broader comparative context of the domestic legislation on museum exchange adopted in selected national jurisdictions. The article also offers a more general cultural policy discussion in the context of international museum exchanges of cultural material. Laws and policies facilitating such exchanges are weighed against other rights and interests encompassed in the protection of cultural heritage and the realisation of all human rights, including cultural rights.     

Testing micro-regional variability in the Holocene shaping of high mountain cultural landscapes: a palaeoenvironmental case-study in the eastern Pyrenees

Previous research acknowledges the ancient and complex land-use history of European mountainous areas, which are characterised by a remarkable regional variability in terms of human practices and patterns of occupation during the Holocene. However, the combined palaeoenvironmental and archaeological study of highland human management at a micro-regional scale remains a largely unexplored research field, especially in the Pyrenees. A combined pollen, stomata, non-pollen palynomorphs (NPPs) and macrocharcoal study was carried out at three nearby alpine and subalpine peat basins from a relatively small territory (ca.1700 ha) at the Madriu valley (Andorra, eastern Pyrenees), following a fine spatial-resolution strategy. The purpose was to test the suitability of high altitudinal palaeoecological sequences when reconstructing past small-scale land-use variability. The palaeoecological results of those peat records are compared and further integrated with archaeological local data, and together underline the marked complexity of high mountain land-use system over the Holocene period. Main phases of micro-regional land-use and landscape variability can be distinguished from the middle Neolithic to the early Bronze Age and from the Roman Period to the Modern Era. Conversely, several phases of homogeneous landscape management are distinguishable during the early Neolithic, and from the late Bronze to the late Iron Age. Results drawn from this study show that landscape variability is not necessarily connected to topographic or climatic parameters, and underline the role of social, economical and cultural parameters in the land-use organisation and the landscape shaping of high mountain spaces since Prehistory.     

Airborne lidar survey of irrigated agricultural landscapes: an application of the slope contrast method

Irrigated agriculture was central to the economies of many of the world’s best known complex societies. New high-resolution digital elevation models (DEM) derived from remotely sensed lidar data give archaeologists the opportunity to study field systems at a scale not previously possible. Here we describe a method called slope contrast mapping that takes advantage of the dissimilarity between artificial and natural slopes to identify and map discrete features. We use this relatively simple method in our own research to identify complexes of agricultural terraces in the North Kohala district, Hawai’i Island. It has also proved useful for mapping the natural landscape, specifically the extent of flat land between valleys suited for irrigated agriculture.     

The Tel Akko Total Archaeology Project (Akko,Israel): Assessing the suitability of multi-scale 3D field recording in archaeology

Abstract

Archaeology is a destructive discipline, and, unfortunately, the majority of methods employed by archaeologists to record and preserve the archaeological record consist of two-dimensional representations of three-dimensional (3D) subjects. Recent breakthroughs in 3D technology, however, have the potential to revolutionize the discipline. In recent years, multiple software suites capable of generating spatially accurate, photorealistic 3D models with a series of digital photographs have become available. Following a successful season of field testing in 2011, the Tel Akko Total Archaeology Project (Akko, Israel) expanded the use of Agisoft’s PhotoScan Pro—one of the commercially available software suites—to test the accuracy and suitability of the program for archaeological applications at multiple scales. After two years of field testing, it is clear that the implementation of PhotoScan Pro in archaeology facilitates unprecedented accuracy in field recording and digital heritage management, and provides a new outlet for the dissemination of archaeological data.     

Tracking tuberculosis in the past: the use of genealogical evidence

A series of mutations of tuberculosis, present in the 1990s among elderly persons in the Province of Quebec (Canada), is interpreted as the outcome of a suite of three episodes of high mobility. The most recent is the rapid urbanization of the 1950s. In the 1840s exceptional mobility was a feature of frontier settlement and exploitation of timber. Unusual mobility in the 1750s and 1760s was associated with wartime conditions of the British conquest of Quebec and re-settlement of Acadian refugees. The scenario was developed from cartographic analysis (using geographic information systems), genealogies of the human hosts, and molecular genetics of the bacterium.     

Exploratory Analysis of the Homeless Shelter System in Columbus, Ohio

Abstract: A geographic information system (GIS)-based framework is structured to analyse the spatial characteristics and patterns associated with a system of homeless shelters and services. Given the lack of detailed spatial information available to decision-makers and shelter operators, the siting of new shelters and services is often carried out with little supporting information. The shelter system in Columbus, Ohio is investigated. Personal interviews with shelter providers and local decision-makers offers a look at their collective understanding of the services needed by Columbus' homeless population and the spatial patterns and socio-economic characteristics that define the neighbourhoods in which shelters are located. The use of GIS facilitates an exploratory data analysis that allows these understandings to be examined, affording planners and decision-makers the opportunity to move beyond perceptions of the system. Findings indicate that while many perceptions are supported empirically, there are perceptions that are not substantiated. This research provides a basis for the evaluation of important social services in an urban area where perception influences planning and decision-making.     

Monumentalization and ritual landscapes at Fort Center in the Lake Okeechobee basin of South Florida

Why do some places seem to emerge out of a void and then continue to be occupied for millennia? How do historical factors contribute to this process? Examples of sites with grand and lengthy occupational histories can be found in the Lake Okeechobee basin of South Florida. Our research at one such site, Fort Center, contributes to the broader theoretical understanding of these issues by examining and evaluating some of the architectural constructions at this famous site. In order to conceptualize such sites, we introduce the concept of persistent monumental places. We use this notion to structure our discussion of geophysical and archaeological data on the earthworks of Fort Center in an attempt to historicize its development as an enduring place as well as microcosm of the surrounding landscape. We suggest that such a perspective aids in the investigation of larger social, economic, ritual, and environmental dimensions related to monument construction and use in the region.     

Using Airborne LiDAR Survey to explore Historic-era archaeological landscapes of Montserrat in the Eastern Caribbean

Abstract

This article describes what appears to be the first archaeological application of airborne LiDAR survey to historic-era landscapes in the Caribbean archipelago, on the island of Montserrat. LiDAR is proving invaluable in extending the reach of traditional pedestrian survey into less favorable areas, such as those covered by dense neotropical forest and by ashfall from the past two decades of active eruptions by the Soufrière Hills volcano, and to sites in localities that are inaccessible on account of volcanic dangers. Emphasis is placed on two aspects of the research: first, the importance of ongoing, real-time interaction between the LiDAR analyst and the archaeological team in the field; and second, the advantages of exploiting the full potential of the three-dimensional LiDAR point cloud data for purposes of the visualization of archaeological sites and features.     

System of measurement of the severity of periodontal disease in past populations

This paper presents a review of the antiquity of periodontal disease, discussing past aetiological concepts in comparison to current research on the causes of this condition. As periodontal disease is analysable on dry bone specimens, it is possible to document its natural history. To date, little work has been done on an actual system of measurement for periodontal disease in such specimens. A new system of measurement is proposed, which is confined to evaluating the periodontal status of post-mortem skulls. The system is a modification of the Ramfjord index for periodontal disease (PDI) and can be adapted for both individual specimen measurement and for population studies. Seven skulls, ca. AD 500–700, from the Varden Site at Long Point, Ontario, were examined using the proposed system. Mean attachment loss was computed for each of the seven specimens. The results revealed one specimen with early periodontitis, four with moderate periodontitis and two with advanced periodontitis. This system provides a concise method for classification of the severity of periodontal disease in dry bone specimens that will be useful in documenting the history of this disease.     

Mapping ancient chinampa landscapes in the Basin of Mexico: a remote sensing and GIS approach

This paper uses remote sensing data to document a raised field, chinampa system adjacent to the Postclassic kingdom of Xaltocan in the northern Basin of Mexico. Various forms of landscape information; historic records and maps as well as remote sensing; are considered to understand the chinampa system. The remote sensing data examined include 1950s aerial photographs, Landsat 7 data, and Quickbird VHR, multi-spectral imagery. This article evaluates the utility of each of these forms of data to identify buried chinampa features and integrates them in a GIS to produce a map of Xaltocan's chinampa landscape. Canals of various sizes and hydrological positions comprised the chinampas and integrated the system together. Occupying at least 1500–2000 ha, Xaltocan's chinampa system represents the largest pre-Aztec, chinampa system in the Basin of Mexico.

Tourism and the management of cultural resources in the Pays Dogon,Mali

Abstract

The Pays Dogon, designated a joint Natural/Cultural World Heritage Site in 1989, is Mali's leading tourist attraction receiving 6,000 visitors per year with an annual growth of 10% which may increase when a new access road is constructed. Tourism is the major source of income for the Dogon who have lived in picturesque villages clinging to the sides of the 600m cliffs of the Bandiagara escarpment since the 15th century. The Dogon are best known to Europeans for their masked dances and powerful woodcarvings, much prized by collectors. Loss of cultural property by illicit trading combined with alteration of the traditional masked dances for visitor preference is contributing to cultural change within Dogon communities. The harmony and cohesion which enabled the Dogon to resist the colonial power is being threatened by a new set of historical constructs and priorities indicating that Dogon culture is more fragile when confronted with the 20th century.

青海历史文化多元性及地域文化命名

目前学术界就青海地域文化的命名共提出“江河源文化”、“青藏文化”等9种文化命名,本文认为青海地域文化命名多样化产生原因首先是由青海历史文化的多元性造成的,而政区和文化区范围界定的不匹配、青海所处特殊地理环境和地理位置以及历史时期移民活动则是注定青海历史文化多元性产生的主要原因。在借鉴其他省份地域文化命名的规律的基础上,建议把青海地域文化命名为“青海文化”,因为“青海”既是历史地名,又是自然实体名,符合已有地域文化命名的规律。文章最后特别指出一个地方的地域文化命名和历史文化定位是两个不同的问题,地域文化名称如人的姓名,只是一种识别符号,所以不可能也没必要全面反映一个地区的文化特点,后者是历史文化定位的内容。针对青海历史文化多元性,建议以分层的方式来解决青海历史文化定位问题。     

Information obtained from the microscopic examination of cultural striations in human dentition

The surfaces of teeth from some fossil remains and archaeological samples have been examined by SEM, in order to study different types of cultural striations and to determine the archaeological information that these striations can provide. Different patterns of cultural striations are present in human samples from different sites and periods. Similar cultural striations can be interpreted in different ways, depending on the tooth in which they are present, their location in the tooth and their direction, regularity, number and width. The study of cultural striations can yield valuable information about different aspects of feeding behaviour, oral hygiene, patterns of cultural diffusion and manipulative work with teeth of past human groups. A close integration with other anthropological and archaeological data is needed and specific interpretations should be made in each case.     

Dealing with the contested past in Serbia: decontextualisation of the war veterans memories

This article addresses the protracted process that took place following the wars of the 1990s through which the war veteran populations in Serbia were fragmented, alienated and marginalised. The main assumption in this paper is that gaining control over the veteran populations was a crucial step in silencing any public reckoning with the nation's criminal past. Drawing on the case study of the top‐down reframing of the war veterans' memories, I show that the most effective strategy was found to be first to fragment the veteran population and then to encourage them to de‐contextualise and reframe their memories replacing concrete historical suffering with abstract remembrance. This resulted in the reinstitution of Serbia's former national narrative of Serbian victimisation. It is suggested that the Serbian case of collective memory reconstruction after the wars of the 1990s is a prime example of how post‐conflict states may mediate their contested past in order to bridge the gap between domestic demands and those of the international community.
