Higher Education and FOSS for E-Learning
No full textThis paper examines the paradox of FOSS adoption in U.S. institutions of higher education, where campus-wide deployment of FOSS for e-learning lags far behind adoption for technical infrastructure applications. Drawing on the fields of organizational management, information systems, and education, the author argues that the gap between the advocacy for FOSS teaching and learning applications and the enterprise-wide deployment of FOSS for e-learning is a consequence of the divergent perspectives of two organizational sub-cultures—the technologist and the academic—and the extent to which those sub-cultures are likely to embrace FOSS. The author recommends (a) collaborative needs analysis/assessment prior to a go/no go adoption decision, and (b) broad dissemination of total cost of ownership (TCO) data by institutions deploying FOSS for e-learning enterprise-wide. This discussion satisfies e-learning administrators and practitioners seeking research-based, cross-disciplinary evidence about the FOSS decision-making process and also assists educators in graduate degree programs seeking to expand student knowledge of e-learning technology options.</jats:p

Testing the human factor: Radiocarbon dating the first peoples of the South Pacific
No full textArchaeologists have long debated the origins and mode of dispersal of the immediate predecessors of all Polynesians and many populations in Island Melanesia. Such debates are inextricably linked to a chronological framework provided, in part, by radiocarbon dates. Human remains have the greatest potential for providing answers to many questions pertinent to these debates. Unfortunately, bone is one of the most complicated materials to date reliably because of bone degradation, sample pretreatment and diet. This is of particular concern in the Pacific where humidity contributes to the rapid decay of bone protein, and a combination of marine, reef, C₄, C₃ and freshwater foods complicate the interpretation of ¹⁴C determinations. Independent advances in bone pretreatment, isotope multivariate modelling and radiocarbon calibration techniques provide us, for the first time, with the tools to obtain reliable calibrated ages for Pacific burials. Here we present research that combines these techniques, enabling us to re-evaluate the age of burials from key archaeological sites in the Pacific
Changing prehistoric Yapese pottery technology: a case study of adaptive transformation

Archaeological investigations in the Yap Islands, Micronesia: first millennium B.C. to the present day. Oxford, England: B.A.R.This study describes the processes of cultural adaptation to environmental conditions through an examination of ceramic technology. The case study involved eight months fieldwork in the Yap Islands, Western Caroline Islands, Micronesia, to obtain archaeological, ethnographic and environmental information.
Analyses of the mineral and chemical composition and physical characteristics of Yapese clays showed that two types exist on the island: very plastic metamorphic clay and nonplastic sedimentary clay. Analysis of sand samples from beach and river locations showed varying amount of calcareous sand grains.
Three types of pottery were distinguished in the archaeological deposits on the basis of temper and physical characteristics of vessel walls. Calcareous Sand Tempered (CST) and Plain potteries were made between 2000 and 600 years B.P. whereas Laminated pottery was made after 600 years B.P. Technological change between the three pottery types was shown by reconstructing the technology used and the physical properties of the products, using information about the mineral composition of the clays, tempering, forming, surface finish, vessel form, thickness, firing, strength and porosity.
Metamorphic plastic clay was used for making all three types of pottery. The major contrasting characteristic of the different potteries is differences in tempering behaviour. A steady improvement in firing technique over 2000 years was identified as the major cause for the changes observed.
CST pottery was tempered with fine calcareous beach sand. The clay tempered in this way was very workable but had a disadvantage of being easily damaged if fired at higher temperatures.
Plain pottery was tempered with a range of materials, such as burnt coral lime and coarse sand but not with calcareous sand. This variation with alternative tempers is interpreted as attempts to avoid the deleterious effects of heating calcareous sand. The quality of Plain pottery was not very high (weak, thick and straighter vessel wall), and the experiments did not result in an effective solution to the problems of CST pottery because technological replacement did not occur.
Laminated pottery was shown to be identical to the historically manufactured pottery, and was made with a unique technology. No temper was added to the highly plastic clay, and the techniques of forming, drying and firing were adapted to the low workability of the clay. The combination of these techniques produced a strong and durable layered vessel wall.

Islands of inquiry: Colonisation, seafaring and the archaeology of maritime landscapes (terra australis 29)
No full textAustrian economics: a tale of lost opportunities
No full textThis is a, somewhat indirect, rejoinder to Boettke (2019, this volume, Chapter 1). Doing Austrian economics is low prestige: Austrian economics does not get published in high-prestige journals and Austrian economists are not employed by top universities. And yet, up until World War II Austrian economics was an important part of the international economics community. The author argues that Austrian economists made several theoretical innovations that could have placed them at the frontier of research in economics, and present a brief coun-terfactual history of a thriving Austrian economics based on those innovations. However, the actual history of the Austrian School is quite different. A par-ticularly decisive factor that has made Austrian economics a fringe movement was the rejection of formal methods in theory and empirics. The author argues that Austrian economics is basically dying out as a voice in the conversation of modern economists
