This paper reports on a study of 18 of the 20 first round of community online access centres introduced in Tasmania, the only island state of Australia. The access centres were designed to redress some disadvantages of living and working in rural regions of Tasmania, such as isolation and economic inequity. The investigation aimed to determine and evaluate trends in micro e-business activity associated with use of the centres. Statistical data collected over a two-year period in eighteen community online access centres were utilised. Comparisions were made of five communities with populations of 2 000-15 000, and thirteen with populations below 2 000. Differences were found in micro e-business activity generated in the two population categories. In centres in the larger communities, micro e-business activity was more uniform over ...
Continental shelf waters are subject to the greatest impact by humans. If marine ecosystems are to be efficiently managed and protected from the adverse effects of human activities, then identification of the types of marine habitats and the communities they contain is required. Research cruise data and existing data were collected at three diverse study sites on polar, temperate and tropical continental shelves within Australia's Exclusive Economic Zone (EEZ). This project conducted a multi-disciplinary analysis of satellite imagery, multibeam sonar, seismic profiles, oceanographic data, underwater video, and the results of sediment sampling. A Geographic Information System (GIS) was utilised to model the spatial boundaries of the physical and biological datasets. Spatial and multivariate statistical analyses were conducted on the GIS...
Mitochondrial DNA haplotypes from the displacement-loop (D-loop) region (436 bp) were genotyped and sequenced in Japanese Black beef cattle raised in the same herd. Correlation coefficients between mitochondrial DNA haplotypes, maternal lineage, birth weight, preweaning average daily gain, weaning weight, post weaning average daily gain and yearling weight were computed. The objective was to study the relationship between maternal and postnatal growth traits and to investigate if postnatal growth of calves to yearling age could be accurately predicted from mitochondrial DNA haplotypes. Results of the phylogenetic analysis revealed 17 maternal lineages and four mitochondrial DNA haplotypes. There were strong, positive and highly significant (p<0.001) correlations among maternal traits ranging from 0.52 to 0.98. Similarly, among postnata...
This document was produced under request from the Water Quality & River Health Section of the Department of the Environment and Water Resources (DEW). It was written based on the experience and opinions of the author and with input from key state/territory (jurisdictional) agency staff and specialists. Its aim is to review and comment on the utility of AusRivAS, and its possible future governance and funding arrangements.
Alaskan-type platinum-bearing plutons and potassium-enriched mafic to ultramafic volcanic rocks are temporally and spatially associated within the Late Cretaceous-Paleocene Achalvayam-Valaginskii intra-oceanic palaeo-arc system, allochthonousy present in the Kogak Highland and Kamchatka Peninsula (Far East Russia). The compositions of the parental magmas to the Alaskan-type complexes are estimated using the Galmoenan platonic complex as an example. This complex, composed of dunites, pyroxenites and minor gabbros, is the largest (~ 20 km3) in the system and the best studied owing to associated platinum placer deposits. The compositions of the principal mineral phases in the Galmoenan intrusive rocks [olivine (Fo(79-92)), clinopyroxene (1-3.5 wt % Al2O3, 0.1-0.5 wt % TiO2), and Cr-spinel (5-15 wt % Al2O3 and 0.3-0.7 wt % TiO2)] are typic...
Immiscible phase separation during the cooling and crystallisation of magmas is an inherently fugitive phenomenon and melt inclusions may provide the only remaining evidence of this process. We detail those features of such inclusions that can both prove the existence of immiscible phase separation, and constrain the compositional signature of the process. To do so requires the combination of traditional methods (petrographic examination, microthermometry, etc.) with state of the art microbeam analytical techniques (laser Raman spectroscopy and proton-induced X-ray emission). Examples of inclusions in phenocrysts from barren and mineralised rocks are provided to illustrate the approach and validate the interpretations.
Three atomic spectrometry techniques, namely sector field inductively coupled plasma mass spectroscopy, graphite furnace atomic absorption spectrometry and hydride generation atomic fluorescence spectroscopy (ICP-SMS, GF-AAS and HG-AFS, respectively), housed at separate independent laboratories, were used to analyse water and sediment samples collected from the Huon River Estuary, SE Tasmania (Australia) in the Austral spring 1998. A dithiocarbamate-chelation/back-extraction technique was used to separate and preconcentrate Co, Ni, Cu, Zn, Cd and Pb from eight collected water samples prior to analysis by ICP-SMS and GF-AAS. A number of other elements in the waters were analysed directly (Mn, Fe and Zn by GF-AAS; As by HG-AFS), or following sample dilution (1 + 19; V, Mn, Fe, As, Mo, Ba and U by ICP-SMS). Where possible, previously corr...
This document summarises the Independent Sustainable Rivers Audit Groups (ISRAG) main findings from the sampling conducted during the SRA’s Implementation Period 1 (2004-05), or IP1. The initial results are described from the first round of sampling of fish and macroinvertebrates from the subset of river valleys sampled in 2004-05. It should be noted that these results are preliminary. SRA Annual Implementation Reports, as distinct from 3-yearly SRA Reports, are not intended to provide final assessments. Results of more detailed and comprehensive analyses, for all Basin valleys, will be presented in ISRAG’s triennial SRA Reports.
The behavior of researchers when self-archiving in an institutional repository has not been previously analyzed. This paper uses available information for three repositories analyzing when researchers (as authors) deposit their research articles. The three repositories have variants of a mandatory deposit policy. It is shown that it takes several years for a mandatory policy to be institutionalized and routinized, but that once it has been the deposit of articles takes place in a remarkably short time after publication, or in some cases even before. Authors overwhelmingly deposit well before six months after publication date. The OA mantra of 'deposit now, set open access when feasible' is shown to be not only reasonable, but fitting what researchers actually do.
