The oral health consequences of the adoption and intensification of agriculture in Southeast Asia

Abstract: Introduction In 1979, Christy Turner put the Asia Pacific region on the global bioarchaeological radar with his highly cited paper characterising subsistence economies using mean caries frequencies. Collating dental caries data from some 64 samples, Turner (1979, p. 622) found a mean caries frequency for hunter–gatherers of 1.3%, for mixed economies of 4.8% and for agriculturalists of 10.4%. Rose et al . (1984) also posited a quantitative benchmark where a mean carious lesion rate per individual exceeding 2 indicated agricultural dependency. In fact, the contributions in the widely cited book by Cohen and Armelagos (1984) helped to formulate a consensus view that the frequency of carious lesions will increase with the move from foraging to agriculturally oriented subsistence bases, at least in the maize-based economies on the North American continent. Other contributions to that volume detailed the same correlation between increasing frequencies of lesions and intensification of millet-based agriculture in North Africa (Martin et al . 1984) and of barley- and wheat-based agriculture in the Levant (Smith et al . 1984). Lukacs (1992) has also documented the same trend in South Asia with the intensification of wheat and barley agriculture. With respect to Europe, Molnar and Molnar (1985) argued not so much an increase in carious lesions per se but rather for a high prevalence of root lesions with the increased use of unspecified domesticated grains. It is also worth pointing out that other types of grain have been associated with this apparent global trend.

Productivity analysis for Vietnam’s textile and garment industry

Abstract: The study uses firm-level panel data to study the technical efficiency performance of Vietnam’s textile and garment firms in the period 1997-2000, as well as its determinants. The model used is that of Battese and Coelli [1995]. The average estimated technical efficiency of the two subsectors is relatively high. In the textile subsector, medium-old, South-based, private, export-oriented, and highly equipped firms are found to be more technically efficient than those with differing characteristics. In the garment subsector, large or old-medium, south-based, and high external capital firms have higher technical efficiency. Meanwhile, small, old, and highly equipped firms have lower technical efficiency than firms with other characteristics. The total factor productivity (TFP) picture of the textile subsector is mixed, whereas the TFP growth of the garment subsector is positive, although this growth decreases. JEL classification: O47, O33
