Reinventing Imperata: Revaluing Alang‐Alang Grasslands in Indonesia

This article takes a new look at the economic value and cultural significance of Imperata cylindrica grasslands in Indonesia, drawing particularly on fieldwork in Bali, Lombok and West Timor, where the focus is on the use of alang‐alang grass for roof thatch. The development of tourism has resulted in the commodification of thatch in Bali and Lombok for quality roofing and insulation. With its visual impact reinforcing its traditional cultural significance, the thatched roof has become a tourist artefact, its resulting high price elevating Imperata to the status of temporary cash crop and lucrative export. In West Timor, on the other hand, the grass has become a scarce commodity for roofing traditional houses. While it lacks the high prices of Bali‐Lombok, in Timor the cheapness of thatch in this time of economic crisis has increased its value over alternatives. This article explores the valuing and revaluing of Imperata within various agro‐ecological and economic niches, and provides case studies of some of the highly adaptive and opportunistic responses of local people to land‐use change. While the Bali case represents an extreme example of the grass as commodity, the more significant view of its value is the place it continues to occupy, in a subsistence or contingency sense, in many rural economies.

WHAT I BELIEVE ABOUT THE USEFUL DIVERSITY OF THEORY IN SOUTHEASTERN ARCHAEOLOGY

Theory is crucial but has become boring and unintelligible; it is often ignored by most professionals. Archaeology must include a foundation of culture history, processual science, and postprocessual imagination and counteraction of bias. Further, all archaeology should aim for public aspects and practical applications. Theoretical writing must be clear and avoid pretension. Gender bias in Southeastern archaeology is one of the worst distortions of the prehistoric record for what were probably matrilineal societies. Diverse humanistic approaches from many (including non-archaeological) viewpoints can provide worthwhile avenues for investigation with new scientific tools. Narrow interpretive frameworks should be avoided in favor of the delightful banquet of multiple simultaneous or blended approaches.     

Protocol for Recording Enamel Hypoplasia in Modern and Archaeological Caprine Populations

This paper outlines the first methodology for recording dental enamel hypoplasia in the high‐crowned dentition of modern and archaeological caprine teeth. The method has been developed and trialed on five caprine populations from Orkney (UK); two modern populations (Shetland and North Ronaldsay breeds) and three Neolithic assemblages from the archaeological sites of Knap of Howar, Skara Brae and Holm of Papa Westray. Problems associated with differential tooth wear, as well as the presence of coronal cementum, are discussed, and recommendations are given on the identification and recording of hypoplastic dental defects in caprines.

Dental Pathology,Trauma and Attrition in a Zambian Iron Age Sample: A Macroscopic and Radiographic Investigation

Using morphological and radiographic methods, we analysed the dentitions of 24 individuals from Ingombe Ilede and Isamu Pati Zambian Iron Age archaeological sites. In this study, we determined the frequency and distribution of attrition, pathological conditions and dental trauma. This research also presents the first view of dental health for an Iron Age population in southern Africa. In total, 482 teeth were available for this study with 287 teeth missing, where 50 of these were lost antemortem and one individual had an erupted supernumerary first mandibular incisor. With the use of radiography and morphology, 21.5% (104/482) of the analysed teeth had at least one pathological condition or evidence of dental trauma. Some interesting dental aspects found and discussed in this paper are linear enamel hypoplastic lesions, radicular resorption, periapical lesions, fractures, dental modification and carious lesions. Many of these features were diagnosed with radiography, and this was especially important for those found below the cemento‐enamel junction (p = 0.0202) that are less obvious with macroscopic investigation alone. Additionally, the quantity and direction of dental attrition was studied. There were observed sex differences with the direction of wear, likely representing a sex‐specific cultural practice of using teeth as tools. Overall, the results show that this sample suffered relatively little from dental problems, and many of those observed features were associated with the traumatic procedure of dental modification, whereas others were age and diet‐related. Additionally, with the use of radiography, rare dental fractures and other features were diagnosed; these results demonstrate the requirement for its application in dental studies on archaeological assemblages.

Manipulating the Maritime Cultural Landscape: Vernacular Boats and Economic Relations on Nineteenth-Century Achill Island,Ireland

Resistance to British control of Ireland’s maritime landscape under the United Kingdom of Great Britain and Ireland (1800–1922) was highly localized, enacted in part through Irish choices in boat construction and patterns of movement at sea. British naval authorities overseeing Achill Island in County Mayo used both coercive and conciliatory means to replace Irish subsistence fishing from regional vernacular boats with commercial fishing from larger non-local vessels reliant upon piers and dredged harbors. These changes encouraged islanders’ dependency upon imported food and wage-based employment performed under Protestant surveillance. Indigenous boats including curraghs and yawls played central roles in Irish resistance to these changes, through the assertion of traditional lifeways and practices.     

The Challenges and Potentials of Archaeological Heritage in Africa—Cape Verdean Reflections

This paper considers three different ways that heritage can be considered fragile—as a reference to the conservation status of the physical heritage, as a concern for the meaning of the heritage, and in terms of threats to the knowledge potentials. It also briefly considers any special conditions that may characterise the threats to heritage in Africa and the consequential challenges to its heritage managers and politicians. On this basis, the experiences of working on one of the first systematic archaeological projects in Cape Verde are used to think about how these challenges are encountered within a specific place but from the viewpoint of foreigners and archaeologists.     

An assessment of the luminescence sensitivity of Australian quartz with respect to sediment history

This study provides a preliminary systematic characterisation of OSL sensitivity, with respect to sediment history, of single grains of Australian quartz from a variety of source rocks and depositional contexts. Samples from two distinct lithologies and with relatively short modern sedimentary histories were compared in an examination of the influence of rock type on OSL sensitivity. Sediments derived from weathered sandstone were found to be brighter than those from metamorphosed schists, suggesting that sensitivity may be inherited from the source rock and its earlier sedimentary history. Secondly, quartz from the same source, but different modes of deposition, was compared to assess the effect on sensitivity of nature of exposure to light during the most recent bleaching event. Quartz grain sensitivity appears not to vary depending on the mode of sediment deposition, suggesting that the nature of exposure to light during deposition is less important in the sensitisation process. This study highlights the complexity and variety of natural sedimentary quartz, demonstrating the limitations of an investigation based solely on OSL sensitivity. Further systematic investigation into the physical, geological and geomorphological characteristics of sediments is proposed to better understand the mechanisms of luminescence sensitisation in quartz.
