Intentional dental modification, in the form of ablation and filing, is reported for the first time from Cambodia in two late prehistoric sites (Phum Snay and Phum Sophy, c. 2500 to 1500 bp). Bioarchaeological research is relatively new for this region, and this study significantly adds to our reconstruction of past behaviours in mainland Southeast Asia. The skeletal samples combine both excavated material and large looted collections in the form of ossuaries. People from Phum Sophy and Phum Snay had similar rates of anterior maxillary dental ablation, 60 and 47%, respectively, and 21.4 and 7.7%, respectively, in the mandible. Patterns of ablation most commonly involve the removal of the maxillary lateral incisors. Intentional filing was less common than ablation but affected Phum Snay and Phum Sophy individuals to a similar level (4–7%). Filing was also restricted to the anterior dentition, and a range of patterns were evident, many involving filing of the mesial and distal aspects of the crown of the upper and lower incisors and canines to give a pointed appearance. Patterns of ablation or filing were not strongly associated with a particular sex or age group. However, a limited number of ablation and filing patterns were exclusive to each site. The significance of this practice in relation to rites of passage, status, community and family relationships, and trauma is discussed. It is also shown that the modifications show distinct differences in prevalence and pattern, particularly that of filing, to nearby temporal neighbours in southern Cambodia and northeast Thailand, suggesting a unique cultural behaviour for this region.

<p class="1Abstract"><span lang="EN-US">Non Ban Jak is a large, moated site located in the upper Mun Valley, Northeast Thailand. Excavations over three seasons in 2011-4 have revealed a sequence of occupation that covers the final stage of the local Iron Age. The site is enclosed by two broad moats and banks, and comprises an eastern and a western mound separated by a lower intervening area. The first season opened an 8 by 8 m square on the eastern mound, while the second and third seasons uncovered part of the low terrain rising into the western mound, encompassing an area of 25 by 10 m. The former revealed a sequence of industrial, residential and mortuary activity that involved the construction of houses, kiln firing of ceramic vessels and the interment of the dead within residences. The latter involved four phases of a late Iron Age cemetery, which again incorporated house floors and wall foundations, as well as further evidence for ceramic manufacture. The excavation sheds light on a late Iron Age town occupied at the threshold of state formation.</span></p>

ABSTRACT. We present the first radiocarbon dates from previously unrecorded, secondary burials in the Cardamom Mountains, Cambodia. The mortuary ritual incorporates nautical tradeware ceramic jars and log coffins fashioned from locally harvested trees as burial containers, which were set out on exposed rock ledges at 10 sites in the eastern Cardamom Massif. The suite of 28 14 C ages from 4 of these sites (Khnorng Sroal, Phnom Pel, Damnak Samdech, and Khnang Tathan) provides the first estimation of the overall time depth of the practice. The most reliable calendar date ranges from the 4 sites reveals a highland burial ritual unrelated to lowland Khmer culture that was practiced from cal AD 1395 to 1650. The time period is concurrent with the 15th century decline of Angkor as the capital of the Khmer kingdom and its demise about AD 1432, and the subsequent shift of power to new Mekong trade ports such as Phnom Penh, Udong, and Lovek. We discuss the Cardamom ritual relative to known funerary rituals of the pre-to post-Angkorian periods, and to similar exposed jar and coffin burial rituals in Mainland and Island Southeast Asia.

Objectives: To investigate the perceptions of Australian health and medical researchers 4 years after the Wills Report recommended and led to a substantial increase in health and medical research funding in Australia. Design, setting and participants: A telephone poll of 501 active health and medical researchers, conducted between 28 April and 5 May, 2003. Main outcome measures: Researchers' views on the adequacy of funding, infrastructure and support, salary, community recognition, the excitement of discovery and research outcomes such as publication and patenting in research. Results: Research funding was the most important concern: 91% of researchers (455/498) viewed funding as "very" or "extremely" important to their role, but only 10% (52/500) were "very" or "extremely" satisfied with the level of funding. Research infrastructure and support were seen as "very" or "extremely" important by 90% of researchers (449/501), while only 21% (104/501) were "very" or "extremely" satisfied. Researchers in medical research institutes were significantly more likely to be satisfied (27% [56/205] "very" or "extremely" satisfied) with the level of infrastructure and support than those working in universities (15% [41/268] "very" or "extremely" satisfied; P = 0.001). Among the factors that motivate researchers, the excitement of discovery stood out in terms of both high importance and satisfaction. Publications were viewed as more important research outcomes than patenting or commercial ventures. Conclusions: Funding and infrastructure support remain overwhelmingly researchers' greatest concerns. University-based researchers were less satisfied with infrastructure MJA 2005; 183: 606-611 and support than those in independent medical research institutes.
