In situ preservation of archaeological bone: a histological study within a multidisciplinary approach

To make preservation in situ a serious option for the management of archaeological sites, research has to be done on the factors affecting conservation of different archaeological materials, including bone. A European project has been started which deals with bone degradation in a multidisciplinary way. The goals of the project are to develop techniques to describe the preservation of archaeological bone, to make a classification of soil environments according to their preservation potential and to detect what factors in the environment of the bone affect its conservation. One technique used in this project to determine the state of preservation of archaeological bone is histology. The relevance of this technique for archaeological heritage management research is discussed.     

UNCSTD: 'geoperspective' of a multidisciplinary commission

Abstract

The term 'safety critical' applies to a wide range of technologies, from car braking systems, through trains and their signalling systems, to advanced air and space technology, both civil and military. It is a rather sophisticated euphemism for 'dangerous';and like the word 'safe', it suggests the existence of some spectral but inherent property beneficial to human health that could be lost under certain conditions, but does not have to be. How far can the discourse about safety be trusted?And why are debates about risk sometimes so heated?In this paper it is proposed that literary theory, particularly work on 'deconstruction' by philosopher Jacques Derrida, can shed some light on these questions. Unsurprisingly, deconstruction cannot say much to safety engineers about the technicalities of system building. But then again questions about whether and why we continue to build and rely upon safety critical technologies are not simply technical; the language used in them is almost always politically charged.     

The transport amphorae of Gela: a multidisciplinary study on provenance and technological aspects

Mineralogical, petrographic and chemical analyses were performed on thirty-eight samples of transport amphorae found at Gela, an important Greek colony on the southern coast of Sicily. Based on macroscopic observation, the amphorae, which are datable between the second half of the 6th and the end of the 5th century B.C., were supposed to be local because of similarities to the common wares from the same site. Therefore, in order to verify the provenance of the samples, they were compared to a reference group of locally made ceramics (kiln spacers, kiln wasters, common wares, ancient mud bricks, modern bricks) and twelve samples of local clayey sediments. The results of the analyses have allowed the assignment of all the amphorae to Gela, with the exclusion of five samples, maybe produced in neighbouring sites, and to determine for the first time the archaeometric characteristics of the Geloan medium-coarse ceramics. The aim of our research has also been to investigate some technological aspects of this production, as the location of the clay sources, the methods of clay preparation, and, in particular, the causes of the typical whitening effect on the surface of the vessels.     

Citizen-led democratic reform: innovations in Indi

Contemporary political systems are experiencing a democratic disconnect between formal institutions of representative government, and the more informal spaces of political participation. Rather than offer an institutional remedy, this article turns to practice and considers how citizens themselves are seeking to transform dysfunctional democratic practices. The article provides an in-depth analysis of democratic events that have unfolded between 2012 and 2017 in the Australian federal electorate of Indi. The analysis explores the intertwined participatory efforts of the citizens’ group, Voices4Indi, and the local Independent federal member, MP Cathy McGowan. The Indi experience demonstrates that while citizens may be frustrated with ‘politics as usual’, they are not rejecting the system but rather instigating creative democratic reforms.

Towards a holistic approach to heritage values: a multidisciplinary and cosmopolitan approach

ABSTRACT

In this paper, we explore the ‘Preservation/Heritage Values/Management’ triptych, and we propose a new method for addressing the values attributed to cultural heritage sites. Combining multidisciplinary and cosmopolitan approaches, we propose a way of moving beyond the traditional lens of assessing significance within the imposed categorical framework of ‘aesthetic, historic, scientific, social or spiritual values’. We provide an example of our new approach through a worked case study in the Maloti-Drakensberg Park World Heritage Site (South African section). Our case study concerns the values associated with the world famous San (Bushman) rock art of this mountain area. Through a thematic analysis of data collected in this area from 2009 to 2017, six cross-cultural interest points are identified and are discussed. Building upon the history of values-based heritage management, we argue that our multidisciplinary and cosmopolitan method is transferable and can be applied to heritage sites around the world. It can facilitate the construction of heritage management plans that are more in tune with local actors and that will therefore prove to be more effective and sustainable.     

Goldsmithing traditions and innovations in colonial Colombia: an analytical study of crucibles from Santa Cruz de Mompox

SUMMARY: The 16th-century Spanish conquest of Colombia brought new technologies that altered and interacted with native metalworking traditions. In the colonial village of Santa Cruz de Mompox, renowned because of its goldsmithing tradition, indigenous groups and Spaniards experienced momentous encounters of individuals, metallurgical technologies and knowledge. However, little is known concerning colonial metallurgy, its continuities and changes with regards to the pre-Columbian period. Here we present the analytical characterization of five crucibles recovered in Mompox, together with discussion of relevant archival evidence. We find evidence for the local manufacture of crucibles as well as for the melting of unrefined gold dust, tumbaga (gold-copper-silver alloys) and silver. These metallurgical practices illustrate some likely illegal activities, continuities with pre-Columbian traditions in the use of tumbagas, and the Spanish-led introduction of silver in northern Colombia. It is argued that metallurgical remains can be informative of wider social and economic negotiations that engaged indigenous peoples, mestizos and Spaniards, which are critical to understand the configuration of the colonial reality.     

Fair Isle: half a century of change

ABSTRACT

Fair Isle is one of the best known of the Scottish islands having given its name to a shipping forecast region and to an internationally known style of knitting patterns and also because it has a world renowned bird observatory, and is the most remote of the inhabited British islands. Over the last five decades it has experienced major changes in its economic and social fabric, reflecting the influences of both endogenous and exogenous forces. This paper reviews and interprets those changes, utilising two surveys made fifty years apart using the same survey instrument and the same methodology in order to provide a basis for a consistent comparison. The paper discusses the changes that have taken place in agricultural practices, in infrastructure, in the economic base and the successful stabilisation of population numbers, and in tourism to the island, which reflect changes in ownership of the island and the impacts of North Sea development and local government re-organisation.     

Transitional change in proto-buildings: a quantitative study of thermal behaviour and its relationship with social functionality

The almost universal transition from ‘brushwood’ huts to ‘pithouses’ to above-ground rectilinear huts constitutes an example of architectural convergence, having occurred in numerous culturally unrelated regions around the world. This transition was accompanied by a pattern of change in the way these proto-buildings performed thermally. A quantitative study using engineering-analysis, outlined here, shows that the thermal microclimatic range and potential for selective thermal control (the building's thermal capacity) gradually increased throughout the proto-building phase. This means that the range of thermally dependent functions that the occupants were capable of performing would have correspondingly increased throughout the phase. This pattern, of increasing thermal capacity and the potential for social functionality that is present throughout the proto-building phase, is also present throughout the vastly longer term trajectory of change evident in the built environment generally. Over time, change in the built environment has tended towards the prevalence of classes of buildings that possess selectively adjustable thermal systems, systems that can accommodate diverse and changing social options.     

Inter-regional migration and social change: a study of South East England based upon data from the Longitudinal Study

"Data from the [Office of Population Censuses and Surveys] Longitudinal Study are used to trace the social class effects of migration between the South East region and the rest of England and Wales in the period 1971-81. The analysis begins with the migration streams into and out of the South East of those people who were in the labour market (including the unemployed) at both census dates. The paper then proceeds to an analysis of the migration streams of those who entered or left the labour market between 1971 and 1981. Finally, the effects of the migration streams on the social class composition of both the South East and the rest of England and Wales are summarised. The results are interpreted in the light of debates about change in the British urban and regional system."     

Ester Boserup's theory of agrarian change: a critical review

As discussions of the positive effect of population growth upon agricutural change have been less common than focus on the negative effects, Ester Boserup's book, "The Conditions of Agricultural Growth," and her subsequent work in which it is argued that population growth is the prime cause of agricultural change is of great importance. The objective of this essay is to review earlier attempts to relate the intensification of agriculture to population growth, to outline Boserup's theory, and to examine the criticisms which have been made of the theory. Boserup maintains that population growth is the cause rather than the result of agricultural change and that the principal change is the intensification of land use. The theory of agricultural development posed by Boserup is more subtle and complex than that of any of her predecessors. She sees population pressure as a major cause of change in land use, agricultural technology, land tenure systems, and settlement form. Boserup argues that population growth is independent of food supply and that population increase is a cause of changes in agriculture. The principal means of increasing agricultural output is intensification. Boserup's work has had a varied response from readers; other economists have been less than enthusiastic. It might seem as if the critics of Boserup's theory have left it in tatters. Her central argument, that intensification reduces labor productivity, remains unproven. There are few who would agree that an increase in the frequency of cropping is the only possible response to population pressure; the extensive margin can be extended, higher yielding crops adopted, and methods that increase yields introduced independently of increases in the frequency of cropping. Emigration or the control of numbers may relieve population pressure. Intensification can also take place without population pressure, under the stimulus of urban growth or the development of trade. It is difficult to accept that population pressure is the only cause or agrarian change or that the increased frequency of cropping is the only response to population pressure, yet the thesis is a fruitful interpretation of agrarian change. Assuming population growth as a change mechanism can lead to important new conclusions regarding the nature of agrarian change in western European history.     

Understanding change in cities: a personal research path

At the invitation of the editor, this article offers an overview of my personal research trajectory in one thematic area—the study of urban form, structure and growth. The purpose of the article is not to assign prominence to any particular research style or approach but to illustrate how ideas and priorities in research evolve over a given time period and under specific conditions, as viewed through the lens of my own experience. The article traces the sequential evolution of my research activity and publications from an initial emphasis on understanding change in inner-city land use and built form, through studies of decision making and the behavioural bases of urban form, to analyses of social change, income inequalities and spatial polarization, and then to issues of planning, policy and governance in emerging city regions. The review highlights lessons learned and concludes with an argument for more inclusive and comparative research.     

Testing the sustainability and sensitivity to climatic change of terrace agricultural systems in the Peruvian Andes: a pilot study

The results of an integrated geoarchaeological and palaeoecological pilot study of a prehistoric agricultural terrace and nearby mire basin are presented. They reveal two stages of terrace construction for the cultivation of Zea mays during the Middle Horizon (615–695 AD) and late, Late Intermediate Period (1200–1400 AD). These stages were strongly associated with evidence for vegetation succession, destabilisation and erosion of the surrounding landscape, and changes in mire surface wetness. The reasons for agricultural terrace abandonment and/or reconstruction are uncertain, with only circumstantial evidence for climatically induced agricultural change.     

Developing baseline data to understand environmental change: a geochemical study of archaeological otoliths from the Coorong,South Australia

Otoliths are calcium carbonate structures found in the inner ear of teleost fish. While they are routinely studied by marine scientists, analyses of otoliths recovered from archaeological sites in Australia and the Pacific have generally been restricted to identification of species and sometimes the fish age. Otoliths can also provide information on the season of catch, and, through trace element analysis, allow the reconstruction of environmental conditions experienced by fish. In this study, we use otoliths from mid- to late Holocene aged archaeological shell middens at the Coorong (South Australia) to examine species present, season of catch, age of fish and environmental conditions experienced by fish. Results demonstrate that the majority of the fish (identified as Argyrosomus japonicus and Acanthopagrus butcheri) were caught in freshwater environments during the warm season, and had grown to an age and size indicative of their having reached sexual maturity. This study provides data indicating fluctuating levels of salinity in the estuary, which are significantly lower than the hypersaline conditions experienced today. Ultimately, this project highlights the usefulness of conducting more detailed investigations of otoliths, including geochemical analyses, to address a wide range of research questions in archaeology and palaeoenvironmental research.     

Model tuning and its impact on modelled climate change response: Hudson Bay sea ice, a case study

The impact of climate model parameterization is examined using Hudson Bay sea ice as a case study. The implicit diffusion of an upstream scheme used in a three dimensional ocean general circulation model is locally determined by using a one dimension proxy model of Hudson Bay with atmospheric, cryospheric and oceanic components. Using this proxy model, distinct pairs of values for the thermal conductivity of sea ice and thermal diffusivity of sea water are found that reproduce the current climatology of sea ice thickness in Hudson Bay. These pairs of values are subsequently used in a 3°C warming scenario. The resulting ice thicknesses are shown to be highly dependent on the choice of these pairs of values as well as the seasonal distribution of the warming.
