Diet and hypertension in the Asia-pacific region : a brief review

In this paper, the possible reasons for the prevalence of hypertension in the Asia–Pacific region are examined, along with its likely dietary, nutritional and sociocultural causes. This brief survey indicates the need for more comprehensive blood pressure monitoring and surveillance throughout the region. Findings from research conducted in the region and elsewhere suggest that a variety of aetiological factors predict the occurrence of hypertension, most of which are similar to those observed in western populations. However, several lines of research suggest that obesity, abdominal obesity and a number of dietary constituents, in addition to salt, may play relatively greater roles than in western populations. It is argued that hypertension may be prevented via a combination of individual, community and governmental approaches which promote social capital, environmentally sustainable food production and the public health.

Observations on ponticocythereis tricristata (Brady, 1880) from the Admiralty Islands, Papua New Guinea and comments on quaternary ostracod evolution within the sw Pacific Ocean

The ostracod species originally described as Cythere tricristata Brady, 1880 from the Admiralty Islands, Papua New Guinea, appears to belong to the SW Pacific and Australasian genus Ponticocythereis McKenzie, 1967 (sensu Warne & Whatley 1996). This interpretation is based on the presence of some posterior pointing scale-like spines on the carapace surface of this species. SEM images of the type material for Ponticocythereis tricristara n. comb., which are presented here for the first time, enable the clear differentiation of this species from the very similar Ponticocythereis ichthyoderma (Brady, 1890), Ponticocythereis quadriserialis (Brady, 1890) and Ponticocythereis laingensis (Wouters, 1981). As a consequence of the subdued manifestation of scale-like or blade-like spines on adult specimens of P. tricristata, this species closely resembles juvenile rather than adult specimens of some other Ponticocythereis species. This ontogenetic/phylogenetic relationship suggests that paedomorphic processes were significant in the Quaternary evolutionary radiation of Ponticocythereis species within tropical SW Pacific and Australasian regions.

Antitropicality of Pacific fishes : molecular insights

Twenty-one molecular genetic studies of thirteen antitropical Pacific fishes are herein reviewed. High dispersal potentials and Plio-Pleistocene transequatorial divergence are suggested for approximately half of the taxa studied, consistent with movement across the tropics during glacial periods. Divergences within two fish groups were mid-Miocene in age, corresponding to a period suggested for vicariant isolation associated with equatorial warming, but high dispersal potentials complicate the interpretation of biogeographic history. Only one study suggested transequatorial divergence older than 20 million years. There is a greater proportion of Pleistocene transequatorial divergences in the East Pacific than the West Pacific, consistent with the suggestion that conditions in the East Pacific are more amenable to the formation of antitropical distributions. Multiple transequatorial divergences have been observed within at least two groups, and instances of cryptic speciation have been identified twice. Areas for future research concern taxa that differ from the majority studied to date with respect to latitudinal distribution, bathymetry, evolutionary age, and dispersal potential. Molecular characters have demonstrated utility for the study of antitropical fishes, but with limitations.

Cheilodactylus (Goniistius) francisi, a new species of morwong (Perciformes: Cirrhitoidea) from the Southwest Pacific

A new morwong, Cheilodactytus (Goniistius) francisi, is recognized from southwest Pacific Islands (Lord Howe Island, Middleton Reef, Kermadecs, and probably Elizabeth Reef, Norfolk Island, and New Caledonia). Distinguishing features from C. (G.) vittatus (Hawaiian Islands) comprise gill-raker counts, caudal-fin coloration, and notable molecular divergence.

Are the earliest field monuments of the pacific landscape serial sites?

Explanations of the origin and genesis of Pacific field monuments commonly assume they reflect local social change in islands or island groups which were increasingly isolated following colonization. A recent review of early West Polynesian archaeology suggests that the penecontemporaneous appearance of various kinds of field monuments from eastern Melanesia to Polynesia may be better explained as evidence of interaction and the movement of people and/or ideas, possibly associated with the colonization of East Polynesia.

Supportng Chinese distance learners through computer-mediated communication- revisting Salmon`s model

Salmon’s (2000) proposed model for the effective development of on-line communication and collaboration between student suggests that on-line socialisation forms an early and important component of establishing required levels of comfort and skill. In this paper we review research with Chinese learners that suggests that some adjustments to Salmon’s model may be advisable for these students. Specifically, the model is redeveloped to provide a more structured experience, and to use that structure to develop online skills, such that comfortable socialisation is seen as an end-point rather than as an early enabler.

Missionaries, music and method - dissemination of tonic sol-fa in Asia-Pacific countries during the nineteenth century

The Tonic Sol-fa method of teaching choral singing and its system of music notation was developed in England by John Curwen and propagated throughout the British Isles as a means of both enhancing Christian worship and achieving social reform. Tonic Sol-fa may be identified as an entirely foreign musical practice introduced to indigenous people in many British colonies and in other overseas countries during the nineteenth century as an instrument of Christian evangelism as well as of European cultural imposition. Nevertheless, indigenous communities were introduced to other aspects of European musical culture including a choral repertoire consisting of four-part hymnody and masterworks by Handel, Bach, Mozart, etc which sometimes resulted in the emergence of a school of indigenous composers writing in Tonic Sol-fa notation and using the tonal harmonic style. The result has been that in several countries-such as South Africa and Fiji for example-Tonic Sol-fa has been so fully assimilated into the ethnic culture that it has been "indigenized" and may now be said to represent a significant exogenous aspect of the musical culture in these countries.

Tonic Sol-fa was most commonly introduced to countries in the Asia-Pacific Region -as in Africa - by Christian missionaries who sought to exploit the attraction of hymns, particularly when sung in four-part harmony, as a means of evangelizing indigenous people who frequently regarded this aspect of missionary activity as a form of "magic". In particular, the Tonic Sol-fa method and notation gained a significant foothold in what were referred to as the South Sea Islands--especially in Fiji where today, the Fijian Hymn Book (1985 edition) is notated exclusively in Tonic Sol-fa. The vast majority of the Fijians are literate in Tonic Sol-fa notation and congregational singing in four parts is the norm in Fijian churches.

This paper will draw on data from nineteenth century journal sources, particularly The Tonic Sol-fa Reporter (1853-1888) and The Musical Herald (1889-1920), and will document the introduction and dissemination of Tonic Sol-fa in several Asia-Pacific countries where, unlike Australia and New Zealand, the indigenous population has maintained its own cultural and demographic predominance. Countries to be considered will include India, China (including Hong Kong), and Pacific Island nations. There will also be a consideration of the contemporary usage and applications of Tonic Sol-fa in the region, with specific reference to Fiji. It will be argued that countries where Tonic Sol-fa notation has become the norm should resist any external pressure to transfer to the standard staff notation merely for the sake of conformity. In the case of Fiji, almost universal music literacy has been achieved through Tonic Sol-fa and this should be recognized as an enviable social and cultural asset.
