New data on relevant ancient Egyptian wooden artifacts: Identification of wooden species and study of the state of conservation with multidisciplinary analyses

Wood species identification and characterization of its weathering processes are crucial steps in the scientific approach of conservation of wooden cultural heritage. Many precious wooden objects of ancient Egypt are largely present in museums, nevertheless relatively little information is available concerning the nature of timber used and on their status of conservation. To address this gap, the wooden species of three relevant archaeological wood objects (statue, box, and coffin) arising from different Egyptian archaeological sites dated from the Old Kingdom (2,686–2,181 BC) to New Kingdom (1,550–1,069 BC) were deeply studied. Five hardwood and softwood species were identified belonging to Tamarix mannifera, T. gennessarensis, Ficus sycomorus, Vachellia nilotica, and Cedrus sp. Such data confirmed the recurrence of Vachellia and Tamarix among the most common timbers found in ancient Egypt. Scanning electron microscope, Fourier transform spectroscopy, and synchrotron x-ray radiation diffraction were conducted to evaluate the archaeological wood deterioration. The formation of microcracks, biological degradation patterns (fungal colonization), or chemical characterization (accumulation of salts on and in-between wooden cells) were detected. SEM micrographs showed the presence of fungal hyphae and conidial spores on the wooden cells. Significant changes in the chemical wood composition and decrease in the crystallinity index were detected.     

The Use and Deployment of Modern Wood Samples as a Proxy Indicator for Biogeochemical Processes on Archaeological Sites Preserved in situ in a Variety of Environments of Differing Saturation Level

Abstract

In situ preservation of archaeological sites is becoming an ever increasing trend as a means of preserving our cultural heritage. In connection with this the environmental conditions, such as water level, dissolved oxygen, temperature, pH and water chemistry, of a site are often monitored. It is generally agreed that a waterlogged and anoxic environment is essential for optimal preservation conditions but the set-up and maintenance of an environmental monitoring programme can be costly.

This paper discusses the design and use of a system whereby modern samples of wood can, with a minimal disturbance of the soil, easily be deployed and retrieved from archaeological sites. The system was deployed in an unsaturated environment, an environment with fluctuating water levels and a fully saturated peat bog. The samples were assessed after two years using microscopic, physical and molecular biological methods, and the types of wood-degrading organisms seen were compared with the results of environmental measurements. Modern wood samples were used, as the microbial ecology of wood-degrading organisms in these different types of environments is relatively well documented. Preliminary conclusions show that the deterioration processes of modern wood samples in these environments act as a good proxy indicator of the environmental conditions and biogeochemical processes ongoing at a site.     

War on the Mind

Abstract

The new biology, a formidable triad of the disciplines of biochemistry, genetics and cell biology, has given an entirely new insight into disease processes. It is forcefully argued here that this interdisciplinary approach should be applied to tropical diseases. The detailed strategy and possible engineering of a malaria vaccine, as developed at the author's Institute, are cited as an example. But finally, society must decide if the new biology is to be used for research on the diseases of the rich or the poor peoples of this planet.     

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.     

Interdisciplinary Teaching in Health

Abstract

In this brief survey, the author sketches his hopes and the difficulties of introducing an interdisciplinary approach to the academic training of health personnel. The solution would appear to be an organizing framework in which the many medical and health disciplines, their values and end results, could be synthesized into a single interdisciplinary approach. Our quality of life depends on this.     

The Fabulous Tales of the Common People,Part 1: Representing Hadrian’s Wall

Abstract

Hadrian’s Wall is one of the most instantly recognizable ancient monuments in the UK. This paper explores the historical and contemporary visualization practices which have created this iconic image. Moving between the disciplines of archaeology, cultural geography, and heritage and tourism studies, the paper draws upon a variety of data sources such as paintings, photographs, models, and reconstructions to consider how the Wall is visually represented within contemporary public discourse. The paper focuses on digital photography and considers the ways in which images create and sustain particular readings of the Wall’s function and significance. These contemporary representational practices demonstrate strong continuities, and earlier images are used to provide historical context. Emphasis is placed on the monument’s landscape setting in visual representations and the importance of this environmental context for readings of the Wall’s cultural and political significance. The present paper deals primarily with representations of the Wall, but it is argued that these representational practices are also fundamentally embodied. The physical encounters of visitors and archaeologists will be considered in greater detail in the second part of this study (Witcher, forthcoming).     

3D Digital Documentation,Assessment, and Damage Quantifi cation of the Al-Deir Monument in the Ancient City of Petra,Jordan

Abstract

The rock-cut monuments in the ancient city of Petra in Jordan form an outstanding tangible heritage site. Unfortunately, this important part of the world's cultural heritage is gradually being diminished due to weathering and erosion problems. In this research, an approach combining in situ surveying and laboratory analysis is applied in order to provide sufficient and comprehensive data regarding the documentation and evaluation of the status of the Al-Deir monument in Petra. The purpose was not only to quantify the damage, but also to make a first step towards creating a 3D monitoring programme of the deterioration rate. The approach presents a correlation study between the environmental condition and the surface weathering damage, using 2D mapping of the weathering form and accurate 3D realistic modelling from laser scanning and digital photogrammetry. The 2D mapping provides detailed weathering damage information for the entire stone surface of the monument, whereas the 3D modelling provides information on the spatial distribution and texture of the damage. Additionally, the 3D digital model can provide reference data as an exact guide to the restoration needed. In order to support the visual presentation of 3D surface details, a hybrid approach combining data from laser scanning and digital imagery was developed.

Studies of stone texture and spatial distribution of soluble salts were carried out at the monument in order to explain the mechanism of the weathering problem. Relative humidity, temperature, and wind are the main factors in the salt damage process. In order to study the effect of these conditions in the salt crystallization process a series of fieldwork investigations and laboratory work were undertaken. The results show that visible zoning of weathering damage is correlated to different salt concentrations.     

The Results of Cultural Management of the Croatian Archaeological Heritage with Special Consideration for Cost Effectiveness: The Case of Roman Iovia (Ludbreg)

Abstract

During the four seasons of excavations of the Roman town of Iovia-Botivo (present-day Ludbreg, Croatia), a smaller bath and sizeable (presumably public) building were discovered. An optimal plan for presentation was made with all due consideration for the site’s speci?c situation. The plan encompassed scholarly and professional requirements concerning conservation in situ combined with the needs of successful cultural management, thus resulting in alignment between the latter two factors as well as cost effectiveness. By applying the aforementioned principles (which served more as guidelines rather than rigid edicts) and facilitating successful, interdisciplinary cooperation between the national government, the municipal authorities, and researchers, it was possible to provide a sound, legally secure future for this site.     

Conservation of archaeological mosaic pavements by means of reburial

Abstract

In a burial environment ancient mosaic pavements are subject to a variety of mechanisms of deterioration, both physical and chemical. However, many pavements have survived, sometimes in exceptional condition. Additionally, some mosaics that have been discovered in recent times and reburied as a means of protection have also been well preserved. This indicates that reburial can be an effective means of preventive conservation and a viable response to the need for conservation of exposed mosaics on many archaeological sites. For reburial to be successful, risks to the mosaic must be accurately appraised and the design of the reburial must be well specified, following a rigorous conservation methodology.     

Thinking Outside the Box: Interdisciplinary Integration of Teaching and Research on an Environment and Development Study Programme

Abstract

Interdisciplinary education and research are increasingly in demand in land use, environment and development because understanding complex human-nature relationships requires a holistic approach. While the need for interdisciplinarity is acknowledged by most, in practice, traditional disciplines are still accorded greatest scientific recognition. This article illustrates how interdisciplinarity has been approached on an international education and research programme. A major challenge was how to strike a balance between interdisciplinarity and specialization, and a specific model based on problem-oriented group work and specialized research teams was developed which successfully negotiated this divide, according to a comprehensive student evaluation. International co-operation among Denmark, Thailand, Malaysia, South Africa, Swaziland, and Botswana has revealed structural and cultural barriers to the implementation of interdisciplinary programmes. Successful negotiation of these barriers requires personal relations based on long-term commitment which was achieved in this case through the study programme and annual joint student field courses.     

Archaeological site conservation and management An appraisal of recent trends

Abstract

There is an increasing awareness and interest in the issues of archaeological site conservation and management. The acknowledgement of these issues has encouraged greater collaboration between the allied professions of archaeology and heritage conservation. From this is evolving a new body of literature and practice. This paper offers an assessment of the field through a literature review of the past 25 years. The investigation reveals a lack of commonly agreed upon standards, principles and practices and the need for active cooperation between the related disciplines and local communities. It traces the development of the field from isolated material and object studies to recent interdisciplinary conferences. What emerges is a new focus on the archaeological site, as those involved in its protection expand conservation from object or material to an integrative practice of concomitant concerns. A selected bibliography is included.     

Complications and Effectiveness of In Situ Preservation Methods for Underwater Cultural Heritage Sites

Abstract

Underwater Cultural Heritage (UCH) as an outstanding division of the cultural heritage of humanity appears to be crucial and complicated when more general issues regarding preservation and conservation are raised. The essence of in situ preservation should be equally discussable for any kind of archaeological remains; on land or underwater.

There is a long history of different methods and concepts of intervention in a variety of sub-aquatic archaeological sites; from shipwrecks to submerged settlements. This paper will present an introduction to different techniques and theories of preservation and conservation of underwater cultural and archaeological sites since this kind of heritage has scientifically been explored and studied. A range of different preservation methodologies, from total or partial transference inland, to preservation underwater, will be compared; the advantages and disadvantages of each option will be highlighted. Different examples of international best practices will be illustrated. Different types of in situ conservation/protection will be explained and categorized. Furthermore, there will be a focus on the UNESCO Convention of 2001 on Conservation and Preservation of UCH, where the in situ conservation option has been recommended.

Moreover, the technical issue for preservation of UCH sites, either in situ or after displacement, will be explained. The implication of relocation for different sorts of sites and materials will be argued; for example, cases where some sites, such as shipwrecks, would more easily be displaced compared with submerged settlements, villages, or ports.

Finally, by stressing that the state of ‘being underwater’ makes many sites qualified to be regarded as UCH, the in situ preservation approach will prevail that this state is maintained.     

Environmental adjustment and private economic strategies in reindeer pastoralism: Combining game theory with participatory action research

The aim of this article is to suggest a research approach to be used in studies of common‐pool resource problems and the deterioration of reindeer pasture. A frequent strategy in such studies is game theory based on rational choice assumptions. This approach has been criticised, for instance, for the neglect of local knowledge concerning cultural preconditions and for the political implications damaging Saami reindeer‐ecology. Our contention is that such problems can be handled by combining game theory with participatory action research when studying the subject above.     

Does the History of Medicine Begin where the History of Philosophy Ends? An Example of Interdisciplinarity in the Early Modern Era

Abstract

A popular saying attributed to Aristotle states that ‘medicine begins where philosophy ends’—but this principle does not seem entirely valid for the late Middle Ages and the Renaissance, when medicine and philosophy were considered to be integral parts of the same branch of knowledge. For this reason, although today medicine and philosophy are clearly distinct disciplines, historians of ideas cannot study them entirely separately. Indeed, since the early modern era was a period of profound revision of knowledge, probably only a truly interdisciplinary investigation can identify the conceptual shifts and transfers capable of reinstating medicine in its fundamental role in the development of civilisation and modern thought, in particular as a model of a rational knowledge aimed at improving the social good through a fitting interpretation of experience. This article intends to offer arguments in support of such a historiographical approach, and to illustrate certain interesting methodological ideas that emerge from a study in which the history of philosophy and history of medicine cross-pollinate.     

Towards a Theory of Cultural Evolution

Abstract

Previous experience in the development of the mathematical theory of biological evolution, has helped the authors toward their theory of cultural evolution. In this review a constant comparison between the two evolutions, in both directions, has led to an interdisciplinary understanding. Cultural transmission is discussed in detail and the ten major modes of transmission are enunciated; cultural traits are defined and the variance within, as well as between, groups considered. Cultural and environmental selection as well as complex transmission are further aspects leading the authors to the conclusion, that in spite of gross oversimplification, their theory is essential for a rigorous qualitative investigation of cultural evolution.     

Community Conservation and the (Mis)appropriation of Taboo

Community conservation initiatives have long struggled to forge productive relationships with the people living in and around protected areas. Currently, there is enthusiasm among conservation researchers and practitioners regarding local cultural taboos, which often appear to conserve species and landscapes of ecological importance. However, in incorporating local taboos into conservation programmes, there is the risk that these culturally sophisticated institutions are used in a highly reductionist manner. Drawing from ethnographic work in Madagascar, this article highlights how the simplification of cultural taboos can exasperate already fraught relationships between communities and conservation organizations, and undermine the very environmental outcomes that groups seek to promote. This reductionist approach can also lead to the harmful appropriation of local meanings and resources. Overall, while working with local taboos may potentially offer an alternative to neoliberal models of conservation, scholars and practitioners should recognize the dynamic and interconnected processes connected with taboos, instead of regarding them as static and interchangeable products.     

Managing Multidisciplinarity: Lessons from SUBR:IM

Abstract

The complex nature of societal problems has fuelled arguments that such issues can only be addressed by holistic responses which are informed by high-quality policy, practice and techno-scientific research. As a result, research councils are encouraging the development of interdisciplinary research consortia through which the strengths of various scientific and social scientific disciplines can be harnessed to produce coherent, well-informed and cross-disciplinary outputs. Yet the task of managing such projects is problematic. The paper draws on the authors' experiences of managing one such consortium, SUBR:IM (Sustainable Brownfield Regeneration: Integrated Management). We reflect upon the processes and politics of building a broadly-based consortium and argue that, while the benefits of such endeavours can be significant, research councils need to give greater recognition to the barriers that exist to achieving genuine collaboration, such as disciplinary incommensurabilities, centrally imposed constraints and internal resistance. The paper explores these barriers before identifying possible ways forward, including better processes of consortia building, more effective internal structures, focusing on a single case study and recruiting the right mix of academics.     

δ18O Analyses of the Humpbacked Conch (Gibberulus gibberulus): Evaluating a Proxy for Reconstructing Sea-Surface Temperature at Chelechol ra Orrak,Palau

ABSTRACT

In Palau, Micronesia, marine resources, particularly shellfish, played a vital role in human subsistence for millennia. Despite the vast array of molluscan species in archaeological assemblages, there is a dearth of data on nearshore palaeoecology or prehistoric shellfish foraging practices. In this study, we analysed stable oxygen isotopes (δ¹⁸O) values present in the calcium carbonate shell of Gibberulus gibberulus from the Chelechol ra Orrak archaeological site to reconstruct average nearshore sea-surface temperatures (SST) from approximately 1500–1100 cal BP. Modern shellfish samples and environmental data were collected from intertidal zones near the site and x-ray diffraction (XRD) was employed to identify the biomineralogical composition of G. gibberulus. These steps provide necessary information for the selection of the proper oxygen isotope-to-SST conversion formula. The selected formula was applied to δ¹⁸O samples from archaeological shells to reconstruct prehistoric SST averages. The results of this proxy validation study verify that G. gibberulus accurately records ambient SST and can be used to reconstruct ancient nearshore conditions. These findings also contribute to the establishment of an environmental baseline, which can be used to examine how environmental changes may have influenced the availability of molluscan taxa that in turn influenced human subsistence practices through time.     

Ecosystem Management Research: Clarifying the Concept of Interdisciplinary Work

Abstract

Ecosystem management (EM) is a process for addressing environmental problems. It draws on research from multiple disciplines in order to ensure long-term maintenance of socio-ecological systems. The present study evaluates the definition of interdisciplinary work among researchers involved in generating data use (EM). The goal is twofold: to generate further discussions in research supporting EM, and to better situate this research in the broader context of interdisciplinary science. Using an online questionnaire, data was collected from 119 researchers. A cluster analysis identified both distinct and shared understandings of the concept. A logistic regression analysis identified the extent to which personal characteristics and researchers’ understandings of interdisciplinary theory determine definitions of interdisciplinary work. Researchers differ on the terminology but share an understanding about what it is: both a ‘way to do research’ and a ‘way of thinking about research’. Differences between researchers suggest a growing interest in developing deeper engagements with theoretical discussions of interdisciplinarity. Results are discussed in the context of the current state of development of research for EM and its contributions to sustainability.     

World Heritage policy on reconstruction: from exceptional case to conservation treatment

Abstract

International heritage doctrine and the Operational Guidelines (OG) for the Implementation of the World Heritage (WH) Convention discourage the reconstruction of cultural heritage. Only ‘exceptional circumstances’ justify this practice, namely armed conflicts and natural disasters. The UNESCO WH Committee recently expressed its support for the reconstruction of damaged WH properties in view of such circumstances and requested the development of new guidance to address this timely issue (Decisions: 39 COM 7 and 40 COM 7). Guidelines will be prepared and provided to the Committee accordingly (Decision: 41 COM 7). We can therefore foresee revisions and additions to Paragraph 86, which is currently the only guideline in the OG, deemed ‘inadequate’ by the Committee. This research paper brings into focus the status of reconstruction in WH policy formulation and takes a normative position. Drawing on document analysis and the most up-to-date studies, I argue that its status should formally shift from exceptional case ruled out a priori to conservation treatment ruled in. I encourage a fruitful international exchange of ideas among a broad interdisciplinary readership to contribute to policy-making. Readers who dispute my position, no less than those who support it, may come to see reconstruction in a different light.
