We calibrated portions of the radiocarbon time scale with combined 230Th, 231Pa, 14C measurements of corals collected from Espiritu Santo, Vanuatu and the Huon Peninsula, Papua New Guinea. The new data map 14C variations ranging from the current limit of the tree-ring calibration [11,900 calendar years before present (cal BP), Kromer and Spurk 1998, now updated to 12,400 cal B P, see Kromer et al., this issue], to the 14C-dating limit of 50,000 cal BP, with detailed structure between 14 to 16 cal kyr BP and 19 to 24 cal kyr BP. Samples older than 25,000 cal BP were analyzed with high-precision 231Pa dating methods (Pickett et al. 1994; Edwards et al. 1997) as a rigorous second check on the accuracy of the 230Th ages. These are the first coral calibration data to receive this additional check, adding confidence to the age data forming the older portion of the calibration. Our results, in general, show that the offset between calibrated and 14C ages generally increases with age until about 28,000 cal BP, when the recorded 14C age is nearly 6800 yr too young. The gap between ages before this time is less; at 50,000 cal BP, the recorded 14C age is 4600 yr too young. Two major 14C-age plateaus result from a 130 drop in Δ14C between 14–15 cal kyr BP and a 700 drop in Δ14C between 22–25 cal kyr BP. In addition, a large atmospheric Δ14C excursion to values over 1000 occurs at 28 cal kyr BP. Between 20 and 10 cal kyr BP, a component of atmospheric Δ14C anti-correlates with Greenland ice δ18O, indicating that some portion of the variability in atmospheric Δ14C is related to climate change, most likely through climate-related changes in the carbon cycle. Furthermore, the 28-kyr excursion occurs at about the time of significant climate shifts. Taken as a whole, our data indicate that in addition to a terrestrial magnetic field, factors related to climate change have affected the history of atmospheric 14C.

The Village

ABSTRACT When European colonists arrived in the late 19th century, large villages dotted the coastline of the Gulf of Papua (southern Papua New Guinea). These central places sustained long-distance exchange and decade-spanning ceremonial cycles. Besides ethnohistoric records, little is known of the villages’ antiquity, spatiality, or development. Here we combine oral traditional and 14C chronological evidence to investigate the spatial history of two ancestral village sites in Orokolo Bay: Popo and Mirimua Mapoe. A Bayesian model composed of 35 14C assays from seven excavations, alongside the oral traditional accounts, demonstrates that people lived at Popo from 765–575 cal BP until 220–40 cal BP, at which time they moved southwards to Mirimua Mapoe. The village of Popo spanned ca. 34 ha and was composed of various estates, each occupied by a different tribe. Through time, the inhabitants of Popo transformed (e.g., expanded, contracted, and shifted) the village to manage social and ceremonial priorities, long-distance exchange opportunities and changing marine environments. Ours is a crucial case study of how oral traditional ways of understanding the past interrelate with the information generated by Bayesian 14C analyses. We conclude by reflecting on the limitations, strengths, and uncertainties inherent to these forms of chronological knowledge.

The most recent estimates, published in 2016, have indicated that around 70% of anaesthesia providers in Papua New Guinea are non-physician anaesthetic providers and that they administer over 90% of anaesthetics, with a significant number unsupervised by a physician anaesthetist. Papua New Guinea has a physician anaesthetist ratio estimated to be 0.25 per 100,000 population, while Australia and New Zealand have a ratio of 19 physician anaesthetists per 100,000, which is 75 times that of Papua New Guinea. To reach a ratio of seven per 100,000, recommended as the minimum acceptable by the Lancet Commission in 2016, there will need to be over 35 practitioners trained per annum until 2030, at a time when the average annual numbers of recent years are less than three physicians and less than five non-physician anaesthetic providers. We review the development of anaesthesia administered by non-physician indigenous staff and the stages of development from heil tultuls, dokta bois, liklik doktas, native medical assistants, aid post orderlies, and Anaesthetic Technical Officers up to the current Anaesthetic Scientific Officers having attained the Diploma in Anaesthetic Science from the University of Papua New Guinea.

Abstract Bats represent an important, but poorly known component of mammal diversity in Papua New Guinea (PNG). Our surveys in two altitudinal rainforest gradients recorded 43 bat species of which six (Dobsonia minor, D. praedatrix, Hipposideros calcaratus, H. maggietaylorae, Miniopterus australis, Miniopterus sp.) fell outside of their known altitudinal ranges. This enlargement could reflect the lack of past sampling, or a genuine range extension, potentially in response to climate change. Our study highlights the importance of baseline data on the altitudinal distribution of vertebrates, including bats, in PNG for the monitoring of their response to climate change and anthropogenic disturbance.

This paper examines a number of recent empirical studies of local-level decision-making in relation to development planning and, especially, the allocation of state development funds in Papua New Guinea. The discussion is framed by the extensive theoretical and Papua New Guinea literature on patronage politics and political culture, by the recent history of decentralisation reforms, and by the frequently articulated, but largely anecdotal, observations about the functioning of district and local-level governance processes.In contrast to the anecdotal vision of widespread and chronic dysfunctionality, the studies considered here paint a picture of considerable spatial and regional variation. We offer some tentative hypotheses to explain this variation, while flagging the need for more empirical work. We outline how these preliminary findings have informed a program of research that is currently being undertaken at the district and local government levels with a view to gaining a better understanding of the extent and nature of spatial variation in the local-level governance of state development funds in Papua New Guinea.

AbstractOriginally intended to provide an accessible overview for colleagues in Papua New Guinea, this article outlines the emergence of the continental division of the world in classical antiquity. In medieval Europe this survived as a learned conception which eventually acquired emotional content. Nevertheless, the division was still within the context of universal Christianity, which did not privilege any continent. Contrary to the views of recent critics, the European sense of world geography was not inherently ‘Eurocentric’. While Europeans did develop a sense of continental superiority, Americans, Africans, and many Asians also came to identify themselves with their continents and to use them as weapons against European domination. The application of the division to Melanesia is also considered.
