Methodology,consetvation criteria and performance evaluation for archaeological site shelters

Abstract

The many intersecting issues that arise when deciding whether to shelter an archaeological site should be approached using a values-based methodology, one that has demonstrated its validity arid practical worth in conservation over recent decades. Nonetheless, pitfalls abound in the decision-making process and in establishing effective conservation criteria which should be based principally on a thorough understanding of the threats to the resource and the specific deterioration mechanisms operating, with the objective of creating a shelter that will preserve the site's identified values. An aspect that has received almost no attention in the past is evaluation of a shelter's performance, both qualitative and quantitative, in preserving the site. It is urged that this receive priority when establishing the conservation criteria during the initial phases of a sheltering project. Issues are illustrated from a range of diverse sites, including a number of published shelters. The paper first looks at the examples of the Laetoli (Tanzania) and Lark Quarry (Australia) trackway sites in the context of decision-making and conservation criteria, and then discusses two examples of evaluation: one quantitative, using an experimental shelter and the other discussing publications on a petroglyph site shelter.     

The Underdeveloped Historical Dimension of the Study of Community Power Structure

Abstract

This article presents a technique of standardising and coding textual birthplace and occupation strings in the censuses of England and Wales and Scotland, 1851–1911. While the approaches for the two text strings are different, they are both based upon the integration of computer technologies, mathematical methods, and expert knowledge. Both processes are described formally using Structured Analysis and Design Technique methodology. The classification of occupations is defined by two algorithms based on statistical decision theory in order to allocate codes from the original occupation strings. The method of standardising parishes is based on the comparison of original birthplace strings and reference data.     

Preserving a Monument: The Example of the Parthenon

Abstract

The preservation of architectural relics of the past developed as a science mainly in the last century. The more a ruin is preserved, the more information it may provide about the past. Structural interventions on relics aim to improve their state of preservation for the future, as well as to render their shape more complete, for the overall purpose of safeguarding their historical information. Over the course of past decades interventions have undergone many changes with respect to methodology, materials, and scope. Intervention in the name of preservation can be interpreted in various ways and questions concerning the goals and nature of modern interventions have become particularly relevant. The current Parthenon Restoration Project, which differs in basic aspects from its predecessors, follows international guidelines for interventions, but remains distinctive for its extent as well as its methods of execution. This paper discusses the theoretical approach underlying the intervention and practical aspects of its methodology.     

‘Site unseen’: the case for reburial of archaeological sites

Abstract

The decision-making process for managing and conserving archaeological sites is increasingly accepted as being driven by a thorough assessment of values, physical condition of the resource and the management context. Reconciling the results of these assessments, which may point in different directions, to arrive at a decision that is most appropriate for the resource can be a complex process. When reburial (also referred to as backfilling) is being considered as an option for the preservation of an excavated site (especially long-term reburial), there are particular opportunities and constraints and a host of considerations (stakeholder, technical and management) that need to be taken into account if the values of a place are not to be compromised and stakeholders alienated. For, however beneficial reburial may be from a conservation perspective, it is generally viewed with scepticism or disfavour by those with legal authority over a site, and by those stakeholders who want access to the site for study, education or money-making. This paper examines the rationales for reburial, as well as the objections to it, and puts forth a decision-making model for reburial interventions that takes into consideration stakeholder, technical and management needs.     

'Joking apart…': A 'processual' approach to researching self-help groups

It is well known that 'feminist research methodologies' reject the traditional and positivistic insistence on detached objectivity, favouring instead a situated and empathic responsiveness to particular research contexts. In practice, however, interviewees often have a justifiable interest in maintaining a communicative distance between researcher and researched, thereby retaining a degree of control over the research process. Although the nature and function of this communicative distancing change over time it may (initially at least) emphasize the boundaries between the respondents' 'insider' and the researcher's 'outsider' status. This phenomenon seems especially pertinent where those researched comprise a tightly knit group with shared interests and experiences such as self-help groups for those suffering from specific disabilities. This paper reflects on my own experiences interviewing agoraphobic women members of two such groups in Central Scotland and discusses the manner in which humour acted as an indicator and facilitator of these changing communicative distances. It concludes that a processual methodology is required in circumstances where managing the research process is often as much a matter of coping with as directing change.     

Structural Assessment of Ancient Masonries before and during a Rehabilitation Process

ABSTRACT

The rehabilitation of old buildings requires detailed knowledge of the mechanical characteristics and stress state of the structural elements, which play an important role in the intervention process. In this sense, non-slightly destructive tests can estimate structural characteristics with good precision at relatively low costs. Consequently, this article presents a device, based on the flat jack technique, applied to continuous stress monitoring over time. It also focuses on the onsite determination of service stresses and its continuous monitoring in several masonry buttresses of a historic building, as well as the assessment of the structural safety before, during, and after an intervention process. A brief analysis of the research is performed, and the motivation and the methodology adopted are described. Finally, the evolution of the measurements recorded and the analysis of the results achieved are detailed. The study enabled recommendations to be made to the intervening agents that guarantee structural safety.     

Children’s independent mobility: the role of school-based social capital

ABSTRACT

Research has documented the decline in children’s independent mobility (CIM) globally. CIM is a measure of the level of a child’s freedom to move about his or her local neighbourhood without direct adult supervision. This paper explores the effectiveness of three intervention programmes to change travel behaviours of children to and from school in 26 Catholic primary schools in a range of urban and regional settings in Victoria, Australia. Using pre and post intervention surveys with 1600 students and parents, and interviews with school principals, we measured the influence of a range of individual, social, and built environment factors on the effectiveness of these intervention programmes. The degree of social connectedness of the school and the individual was found to have the most impact on the effectiveness of the intervention programmes to change behaviours, while the interventions themselves were not greatly effective without being embedded in a supportive school culture.     

A Methodological Approach Towards Conservation

Abstract

Since conservation became a recognized discipline, professionals involved in conservation projects have tried to find the best criteria for their interventions. Often these criteria remain quite vague, based on the idea that every historic building has its own special conditions, which make its problems different from other buildings. This conviction, which is appropriate at one level, has serious consequences due to the lack of a consistent methodology. More than a lack of criteria, we might talk about a lack of 'habit' in identifying values in the Mediterranean region: the concept of values is much more widespread in Anglo-Saxon countries.

If we take a look at the history of conservation, there are a number of cases which are often used as models: for example, the Colosseum or the Arch of Titus in Rome, both interventions which are greatly admired and included in many conservation manuals. More recently there are projects which are widely accepted by the heritage conservation community as well: the paper explores the Palace of the Partal (Granada), the Villa Romana del Casale (Piazza Armerina), the theatre at Orange, and the Insula Orientalis I in Herculaneum. In this article, I suggest that there are constant elements within these conservation projects, reflecting typological, structural, constructional, functional, aesthetic, formal, historical, and symbolic values. These features represent a way of planning a conservation project and a critical methodology to judge the outcomes of the project in an objective manner. The methodology is qualitative rather than quantitative. All historic buildings have a set of values developed from their origins and throughout their history. These values can be analysed to extract the most important elements to be preserved. Analysing the values of our built heritage will allow us to create better decision-making processes.     

Environmental History within a Revitalized Integrative Research Methodology for Today and Tomorrow

Abstract

In the past decades, historians and scientists worldwide have focused intensively on researching and recording the micro and macro trends of the environmental history of many places with reference to numerous aspects of nature that involve people. Yet no definite methodology, epistemology or even theory has resulted from these research contributions, which were and are being conducted within disciplinary and sometimes interdisciplinary frameworks. The transdisciplinary research approach, at least as practiced by historians, is a ‘newcomer’, although it features familiar criteria. For several reasons, some historians appear to be neither in favour of, nor familiar with, research co-operation with other disciplines, private practitioners or informed community members. There are obstacles to using a research methodology that complements the interdisciplinary or transdisciplinary approach, especially the grey areas of research quality, source validity, methodology and publication value. However, if approached constructively and meaningfully, transdisciplinary research may result in what we could call higher-order research because it is all-inclusive and can provide diverse perspectives on any theme, for example, environmental history. This article discusses the possibility of progressing towards ‘transdisciplinary’ as part of an integrative multidisciplinary approach in research on environmental history. An integrative multidisciplinary (‘triangular’) research model is proposed, especially for use by historians and others who want to approach environmental research from disciplinary, interdisciplinary and transdisciplinary perspectives. It is also hoped that this discussion will stimulate the debate by historians on research co-operation with the social sciences and humanities, as well as collaboration with non-related sciences in environmental history.     

Comparing expeditious procedures for the seismic vulnerability assessment on the European territorial context: reliability,feasibility, cost,and time consumption

ABSTRACT

The definition of strategies for the preservation and protection of cultural heritage is a topical issue, especially in view of the increasing relevance of the theme of seismic risk mitigation and reduction.

The prediction of the impact an earthquake could have on existing buildings requires the knowledge of their dynamic behaviour. The procedure to be adopted for this purpose is quite complex and onerous in terms of costs, time, and implementation, especially when the study concerns territorial areas rather than single buildings. The definition of methodologies aimed at respecting the principles of economic sustainability and preserving human life and architectural heritage is of paramount importance to assess seismic vulnerability using available resources. Rapid methods for the seismic vulnerability assessment, aimed at defining buildings vulnerability and intervention priority lists, must be implemented to guarantee the preservation of historical centers.

This article describes the application to some case studies of different methods aimed at creating fragility curves for the vulnerability assessment on the European territorial context. The comparison between a deterministic approach and a new probabilistic one is performed for all case studies, to define the most suitable methodology in terms of reliability and savings in cost and time.     

A Multidisciplinary Study on the Seismic Vulnerability of St. Agostino Church in Amatrice following the 2016 Seismic Sequence

ABSTRACT

The big earthquake of August 24, 2016 and subsequent major shocks severely damaged many historic villages in Central Italy and dramatically showed the intrinsic vulnerability of the diffused architectural heritage. The St. Agostino church is one of the collapsed historical buildings, being inside the epicentre village of Amatrice. During the long seismic earthquake swarm, progressively the church was damaged and monitored. This multidisciplinary study of the damage of the church includes correlations of all the data derived from three steps geomatics surveys (3D aerial and terrestrial models): the archival drawings and images documenting previous events distressing the building, the previous strengthening intervention, and finally the seismic site response analysis (from Amatrice’s accelerometric station). Through a back analysis carried out by a finite elements model, it was possible to understand the seismic vulnerability of this historical building, in relation to the previous interventions and damage events. The proposed methodology, based on the interdisciplinary data analysis, provides useful information for the next strengthening projects of damaged historical monument.     

Restoration Interventions at the Roman Nymphaeum in Amman: Identification and Evaluation

Abstract

Over the last few decades, conservation work has been conducted by the Department of Antiquities of Jordan (DoA) on the Roman Nymphaeum in Amman. This intervention has taken the form of direct and indirect actions. In this article it will be shown that the conservation works concentrated on reinforcing the structure and reconstructing some architectural features of the building, with little consideration of the techniques and materials used. Intervention actions were mostly poor in terms of their scientific approach, and neither proper planning nor a well-defined methodology existed. This study provides a holistic approach for the evaluation of the state of the conservation of the monument in terms of quality and quantity. Thus, the results could be a valuable source for establishing comprehensive risk mitigation for future restoration work and site management. In addition, establishing practical restoration guidelines could help in developing socio-economic benefits for the community through tourism.     

Land Uses and Environmental Conflicts in the Arcachon Bay Coastal Area: An Analysis in Terms of Heritage

Abstract

Coastal zones are specific areas which usually have natural resources of particular interest from ecological and heritage points of view. They are nevertheless subject to considerable pressure because of their attractiveness. Integrated coastal zone management is supposed to take into account these multiple factors in order to preserve natural resources and to allow for coastal development. In this context, land-use conflicts may emerge. This study aims to identify such conflicts and to explain them in terms of heritage conventions. An interesting methodology is implemented, using both focus groups' representations and daily press articles concerning the specific coastal zone of Arcachon Bay in the south west of France. The results raise questions on the link between water and land in coastal land-use management.     

Management of Historic Shipwrecks Through a Combination of Significance and Conservation Assessments

Abstract

Corrosion modelling of decay rates of the iron wrecks in Port Phillip Bay, Victoria, has enabled an estimation of the speed at which the historic resource of iron shipwrecks is disappearing. Use of the significance ranking of the iron wrecks, based on the Australian National Standards for significance assessment, provides a useful guide to decision-making, but decisions based solely on these criteria can lead to less than optimal results. From the corrosion rates and the amount of residual metal thickness in structural elements it is possible to determine a conservation ranking that is based on the need for intervention and the chances of being successful in stabilizing the wrecks. The arithmetic product of the significance and conservation rankings defines the treatment score or ranking which forms the basis for rational decision making about deployment of resources.     

The Officer Corps in Greece (1912–1936)

Abstract

The formation of the modern Greek army coincides with the efforts of the newly established Greek nation of the nineteenth century to import and emulate western institutions. The persistence of most governments in creating an officer corps inspired by the professional standards of western armies may be viewed as part of a general effort to modernize the Greek state. This attempt has invariably been thwarted by traditional practices which prevented modernizing forces from taking firm root in Greek reality. The degree to which professionalism was attained in the army depended both on the quality of military education and on the degree of professional security enjoyed by officers. Lack of security made some officers willing clients of ambitious cliques and agents of disruption of both military and political order.     

Semantically Enhanced 3D: A Web-based Platform for Spatial Integration of Excavation Documentation at Alken Enge,Denmark

ABSTRACT

The photorealistic and geometrically accurate 3-dimensional representation of excavations, provided by image-based modeling, has the potential to transform the process of excavation documentation, making it easier to share observations with other researchers. Paradoxically, however, spatial representation lacks the ability to convey archaeological interpretations. By example of excavations in Alken Enge, Denmark, this paper explores how a web-based 3D platform is able to facilitate the collaborative exchange of 3D excavation content and how the integration of spatial and attribute data into one common event-based data model may be advantageous. This includes enhancing the semantic value of field-recorded 3D models by segmenting the geometry using various techniques, such as 3D projections and machine learning. Accordingly, the paper demonstrates a framework for interactive 3D models, which includes attributed classification based on segmented 3D content correlated with traditional raster, vector, and textual data, delivering a spatially integrated platform for collaborative research.     

TOM JONES (3HE40): GEOPHYSICAL SURVEY AND SPATIAL ORGANIZATION AT A CADDO MOUND SITE IN SOUTHWEST ARKANSAS

Abstract

This article outlines a process that has facilitated discoveries of intrasite pattern, architecture, and diagnostic artifacts at the prehistoric Caddo mound site Tom Jones (3HE40) in southwestern Arkansas. A methodology of multisensor geophysical survey using electrical resistance, electromagnetic conductivity, gradiometry, magnetic susceptibility, high accuracy survey and mapping, and data georeferencing enabled by geographic information system technology has proven to be an efficient, effective, and essential component of an overall research plan. In addition to providing insights regarding the intrasite organization of an upland Caddo ceremonial mound center, this technologically integrated approach has established that Saratoga chalk geology and Blackland Prairie clays combine to form an advantageous medium for geophysical discovery.     

The bodies of others in Swedish feminism

Abstract

The body – or, more specifically, women’s bodies – has long been one of feminism’s central topics. This discussion has ranged from explorations of the cultural meaning of biology to the challenging of classification systems regulating bodies not only culturally coded as female or male but also understood through race regimes. This article seeks to explore the location of bodies within Swedish feminism, examining how women’s bodies are understood, designated and acted upon in feminist agendas. Our focus is on the location that bodies take in political conflicts among and between feminists. In particular, we explore the impact of the presence of black bodies within the field of Swedish feminism. On a theoretical level, this article bridges decolonial feminist contributions of Black, Chicano and Latin American feminist thought on the body. The research methodology combined autoethnography with feminist ethnography, including an analysis of 25 narratives of young feminist activists engaged in public resistance against, and confrontation with, the growing presence of right-wing xenophobic social movements and political parties in the public sphere.     

A Risk Assessment for Cultural Heritage in Southern Iraq: Framing Drivers,Threats and Actions Affecting Archaeological Sites

ABSTRACT

This paper proposes a classification of the risks threatening archaeological sites in southern Iraq and suggests some possible remediation to better preserve them. This has been possible thanks to a research methodology that combines remote sensing and ground control on a sample of 558 sites documented by the Iraqi-Italian QADIS survey project. A three-tier typological framework has been created illustrating the risks jeopardising the cultural heritage of the region. This research showed that the most impacting risks are the ones caused by agricultural activity, despite current narratives which mainly focus on looting and violent destruction. To get at the root of the problem, current laws protecting cultural heritage in Iraq are analysed, as well as how the cultural authorities are organised on the ground. Improving the organisation of the SBAH, engaging the local communities towards the issue of sites’ protection and introducing preventive archaeology are among the solutions proposed.     

Seismic Risk Assessment and Mitigation at Emergency Limit Condition of Historical Buildings along Strategic Urban Roadways. Application to the “Antiga Esquerra de L’Eixample” Neighborhood of Barcelona

ABSTRACT

This article presents a management tool for the large-scale assessment and mitigation of the seismic risk of urban systems. The research introduces a new perspective for a scientifically tackled holistic approach. The proposed methodology considers multiple objectives, from the identification of the most vulnerable buildings whose collapse may hinder the operationality of strategic urban roadways after the occurrence of an earthquake, up to the proposal of proper interventions to improve their functionality. The approach uses a performance-based approach founded on the concept of urban Emergency Limit Condition. Plotting maps of geo-referenced scenarios by means of GIS software have revealed to be extremely useful to detect the weak points of the urban network and to plan suitable strategies of seismic risk mitigation and appropriate enhancement of reliability. The proposed methodology is applied to the “Antiga Esquerra de l’Eixample” neighborhood of Barcelona that hosts the strategic route to the hospital and is characterized by high levels of seismic vulnerability of existing buildings and exposition of its high-density population.
