Short or object-specific counting sequences in a language are generally regarded as early steps in the evolution from premathematical conceptions to greater abstraction and often as cognitively deficient. This paper scrutinizes the main numeration principles in some of the occasionally referenced instances from Melanesia and Polynesia to show that neither assumption holds categorically. The ana...
Most countries in Oceania have adequate quarantine legislation, systems and staff to prevent the introduction of new animal diseases. Surveillance and preparedness for dealing with incursions of such diseases are less developed, except in those countries with larger livestock populations. The degree of preparedness for animal health emergencies in the different countries of the region reflects ...
Abstract Background Since the first study of prevalence autism spectrum disorder (ASD) in 1966, several studies from across world have reported increasing ASD children. This has led to a debate whether childhood cases are real time or increase is essentially due improved accessibility/referral health services changes diagnostic criteria and accuracy. Methods MEDLINE PSYCINFO databases were sear...
This paper commences with a survey of genetic markers thought to give protection from malaria, in connection with the issue of differentiation between An and NAn populations in Oceania. The closely-linked, highly polymorphic human leukocyte antigen (HLA) class II genes, HLA-DR and -DQ, are then examined for evidence of in situ evolution in some Austronesian-speaking populations of Oceania. The ...
Much human adaptation depends on the gradual accumulation of culturally transmitted knowledge and technology. Recent models of this process predict that large, well-connected populations will have more diverse and complex tool kits than small, isolated populations. While several examples of the loss of technology in small populations are consistent with this prediction, it found no support in t...
The history of education in many developing nations is a template of ineffectual and expensive instruction. Despite nearly half a century of higher education in the Pacific, up to 50% of the teachers in many countries such as the Federated States of Micronesia and the Republic of the Marshall Islands still have no more than a high school education. Similar trends are found in Asia and Africa. P...
Since the late 1990s, several Asian countries have developed plans to launch their own navigation satellite systems (NSSs). As a Global Navigation Satellite System (GNSS) is very expensive and complex – only the US and Russia have fully developed GNSSs so far, with Europe and China promising systems – a Regional Navigation Satellite System (RNSS) is a more feasible option. China launched its fi...
It has recently been shown that ancestors of New Guineans and Bougainville Islanders have inherited a proportion of their ancestry from Denisovans, an archaic hominin group from Siberia. However, only a sparse sampling of populations from Southeast Asia and Oceania were analyzed. Here, we quantify Denisova admixture in 33 additional populations from Asia and Oceania. Aboriginal Australians, Nea...
