"Engineering geology of the Patonga Claystone, Central Coast, New South Wales, with particular reference to slaking behaviour." Awarded by:University of New South Wales.

Full textAbstract:
The Patonga Claystone, a red bed facies in the Narrabeen Group of the Sydney Basin, is one of the most unfavorable rock units in the basin from a geotechnical point of view. This rock unit is composed of sandstone, siltstone, mudstone and claystone. One of the unfavorable characteristics is the low shear strength, which causes instability of cut slopes; another is its slaking-prone behaviour. Numerous measurements of geotechnical properties, along with extensive mineralogical and geochemical determinations, were carried out to identify cause of this slaking behaviour. Key techniques were the use of quantitative X-ray diffractometry for mineralogical analysis, and the determination of slake durability index and related properties to evaluate the slaking behaviour under both standard and more extended conditions. Standard (two cycle) slake durability test results indicate a range from low to high slake durability index values, with some mudstone samples having very low durability and some sandstones having very high slake durability indices. Jar slake test results indicate that the rock samples break rapidly and/or develop several fractures (Ij = 4) in an as-received state, but degrade to a pile of flakes or mud (Ij = 1) if the samples are oven dried before testing. The results for jar slake testing of oven-dried material are comparable, for individual samples, to those obtained from the more comprehensive slake durability tests. The mineralogy of the samples was evaluated by quantitative X-ray diffraction techniques using the Rietveld-based Siroquant processing system. Comparison to independent chemical data show a generally good level of agreement, suggesting that the mineralogical analysis results are consistent with the chemical composition of the individual rock samples. Good correlations were also obtained between clay mineralogy determined from orientedaggregate XRD analysis of the <2 micron fraction and the results from powder diffractometry and Siroquant analysis of the whole-rock samples. Evaluation of the slake durability characteristics and other geotechnical properties in relation to the quantitative mineralogy suggests that quartz and feldspar form a rigid framework in the rocks that resists the disruptive pressures that cause slaking. Expansion of the clay minerals by various processes, including the incorporation of water into the interlayer spaces of illite/smectite as well as changes in pore pressures associated with entry of water into micro-fractures in the clay matrix, are thought to produce the disruptions that cause slaking and degradation. An abundant clay matrix also reduces the strength of the rock materials, probably because of the less rigid nature of the clay minerals relative to the quartz and feldspar particles. As well as the mineralogy, the loss on ignition (LOI) and water absorption percentage were found to provide good indicators of longer-term slaking behaviour. Both properties are also related to the overall clay content. Rock samples with water absorption values of <10, 10-15 and >15% behave as highly durable, intermediate and less durable materials respectively. Rocks with LOI values of greater than 5% by weight behave as less durable rock materials, at least for the strata encompassed by the present study. The water absorption and LOI values were also used to develop a predictive model of slake durability characteristics for the different rock materials in the Patonga Claystone, providing a relatively simple basis for predicting longer-term stability in a range of geotechnical studies.

Full textAbstract:
Construction of a 1:250,000 scale regolith-landform map of the Cobar area of central New
South Wales (NSW) Australia, demonstrates the presence of a wide range of previously undescribed
regolith materials, landforms and landscape features in the region. The map covers the east-west extent
of the Cobar Basin, extends to the west onto the Darling River Floodplain, and east onto rocks of the
Girilambone Group. The mapping area is centred on the Cobar township and covers -14,730 krn2
between 303113 and 446113 E and 6483184 and 6586183 N (AGO 66, MGA Zone 55). 48 regolithlandform
units have been identified, including both transported (alluvial, colluvial, aeolian, lacustrine)
and in situ materials. A range of siliceous, ferruginous and calcareous indurated materials are also
present.
Four major drainage types have been identified based on lithological, sedimentological and
topographic differences in alluvial materials. The 4 drainage types include: 1) modern drainage; 2)
maghemite and quartzose gravels elevated 1-2 m relative to the modern drainage; 3) higher
topographically inverted, and at least partly silicified, gravels; and, 4) sediments of Cretaceous origin.
Multiple phases of drainage stability and instability from the Cretaceous to the present are indicated
within the sediments. Breaching of drainage divides and increased dissection of the modern drainage,
especially to the south of Cobar, indicate possible tectonic movement across a major regolith-landform
boundary in the southern map area. Colluvial materials are more widespread to the north of Cobar
reflecting the increased landscape dissection to the south. Colluvial fans are preserved adjacent to
major rangefronts. Aeolian and lacustrine materials include longitudinal dunefields of the Darling
River floodplain, source bordering dunes, and small lunettes associated with the Barnato Lakes system.
Regolith-landform mapping at Cobar has been used to assess the applicability of previously
developed landscape evolution models of the Cobar Block and surrounding region, and to develop a
new landscape evolution model for the region. The new landscape evolution model of Cobar indicates
minimal deposition of Cretaceous sediments, succeeded by high-energy early Tertiary fluvial regimes
across the Cobar landscape. Weathering and sediment deposition continued into the Miocene, coupled
with deep valley incision on the Cobar Block associated with early Oligocene regression. By the close
of the Miocene, the Cobar Block had eroded to predominantly bedrock terrain and widespread filling of
previously incised valleys occurred. A decrease in erosion and fluvial activity led to the formation of
the modern drainage during the Pliocene-early Quaternary, followed by the formation of alluvial,
aeolian and lacustrine deposits in the later Quaternary. Regionally, Eromanga Basin sediments were not
extensive over the Cobar Block, and low rates of erosion are recorded at Cobar from the Cretaceous to
the present. Former northerly drainage did exist in this area in the Cretaceous, but was limited in
distribution. By at least the Early Tertiary the Cobar area was a structural high and drainage systems of
the region had assumed their current configuration. These findings do not support interpretations of
AFTT data of significant cover and subsequent stripping over the Cobar Block in the Early Tertiary.
Evidence of landscape evolution from the Cretaceous to the present suggests that the Cobar
landscape has been responding to changes in the primary landscape forming factors of lithology,
climate and to a lesser degree, tectonics. Variations in the these three primary landscape forming
factors have contributed to ongoing weathering, relatively continuous deposition, and periods of
relative stability and instability, particularly in response to climatic and baselevel fluctuations, within a
dynamically evolving landscape throughout the entire Tertiary. Former landscape evolution models of
peneplanation and pediplanation, based on correlation of palaeosurfaces including duricrusts, a deep
weathering profile developed during extended planation in the Early Tertiary, and tectonism during the
late Tertiary in the Cobar area, are not supported by evidence preserved in regolith-landform features at
Cobar.

Full textAbstract:
The red fox occurs across a very broad range of habitats, and displays great behavioural flexibility under different environmental conditions. In Australia, mounting concern over the impacts of foxes on livestock and native fauna has highlighted a need for more information on fox ecology under Australian conditions as a fundamental step towards developing more strategic means of managing foxes. This study explores ranging behaviour, dispersal, use of dens, activity rhythms, population dynamics and diet in the absence of management in productive agricultural land in the central tablelands of New South Wales. The study was conducted from June 1994 to June 1997 on private property near Murringo, NSW Australia (34°15� S, 148°30� E). The site was primarily sheep and cattle grazing land and had a history of no fox management. Rainfall was considerably below average for much of the study. A total of 83 foxes were trapped over 3931 trapnights, of which 50 were fitted with radio-collars (23 adult and 6 juvenile females, 12 adult and 9 juvenile males) and 26 released with eartags only (all juveniles: 10 females, 16 males). Thirty-three foxes were radio-tracked using fixed towers between March 1995 and December 1996, with between 11 and 28 foxes tracked at any time. Mean home range size was 446.1 ha ± 69.8 se using 95% Minimum Convex Polygons (MCP), and 276.4 ha ± 36.3 se using 95% kernel utilisation distributions. Male home ranges defined by MCP were significantly larger than female ranges, but no significant difference was found using 95% kernels. Core ranges were estimated to be 133.4 ha ± 23.7 se using 50% MCP and 59.8 ha ± 6.1 se using 95% kernels, with no significant difference between sexes. No significant differences were found between range sizes of adults and juveniles or between years or seasons. While most home ranges were steady for the duration of the study, some foxes were observed to shift range location and 4 foxes displayed nomadic behaviour for at least some of the study. There was a high incidence of overlapping home ranges, most commonly between females or males and females but occasionally between males, but core areas were usually separate. Fully overlapping core areas were observed in 1995 but not in 1996.
Juvenile foxes were significantly more likely to disperse than adults, and usually travelled further (juveniles 61.1 km 31.6 ± se; adults 5.9 km 1.1 ± se). Males and females were equally likely to disperse, and there was no significant difference in the distance travelled. The furthest distances were 285 km and 140 km, but mean distance of dispersal excluding these animals was 12.3 km ± 4.3 se (n = 13). Thorough surveys across a 16.4 km² area located 200 dens, with 68 of these active in 1995 and 96 active in 1996. Density of breeding foxes was estimated to be 0.55 and 0.52 adult foxes/km² in 1995 and 1996 respectively based on natal den counts. Density estimates based on active den counts, which include non-breeding foxes, were 0.91and 1.30 foxes/km² in 1995 and 1996 respectively. These estimates appear lower than other studies in similar habitats but this is likely due to using a half home range boundary strip around the surveyed area in the present study. Application of mark-recapture analysis found very high �recapture� rates of dens and gave a similar estimate of the total number of dens to that observed directly. Natal dens were regularly distributed across the study area, whereas active dens tended to be in clusters. There was a high turnover of which dens were used each year, but the total number of natal dens was similar across years (16 in 1995 and 17 in 1996). Natal dens were more likely to be used on repeat occasions than other dens, but not necessarily by the same vixen. Litter size based on sightings of emergent cubs was 2.8. Foxes were predominantly nocturnal, with a major peak in activity about an hour after sunset. A new method of analysing activity rhythm data using Fourier series to mathematically describe animal movements was developed, that allowed systematic identification of the cyclical components underlying overall movement patterns. General fox behaviour could be clearly described by a 24-hour and a 12-hour cyclical component when corrected for variation in daylength. The rising and setting of the sun appeared to be a major trigger underlying movement patterns. Seasonal and sex differences were observed in patterns of activity. The annual rate of increase of the fox population was found to vary around a mean of zero between June 1994 and June 1997. A major drop in fox numbers as estimated by spotlight counts occurred in the second half of 1995, but numbers recovered by the
end of 1996. Kaplan-Meier analysis of radio-tagged foxes found annual adult survival was generally very high (0.56-0.96) with lowest survival between July and October. Causes of mortality were human-related outside the site and apparently of natural causes within the site. However foxes dying of natural causes outside the site were unlikely to be found. There was no overall movement of foxes into or out of the site. Immigration was detected following the drop in fox numbers in late 1995, but there was no evidence of immigration prior to this period although emigration occurred. A sensitivity analysis was conducted on the effects of a small change in life history parameters on finite rate of increase using published data as well as adult mortality data from the present study. The two most influential life-history parameters were adult and juvenile survival, while changes in fecundity and age at first reproduction had much less impact on finite rate of increase. In terms of management, in which fertility control is being considered as an alternative to lethal control, this implies that a small change in fecundity may cause less change in the rate of increase of foxes than lethal control. Foxes were culled in June 1997 on completion of the study. Estimated density using a Petersen estimate was 2.4-5.3 foxes/km² and index-manipulation-index was 1.4-3.2 foxes/km². The different methods used to cull foxes appeared to target different age groups within the population, and were generally biased in favour of younger foxes. Success at killing animals was low, leading to large standard errors in the population estimates. Stomachs of foxes shot in the Orange district were found to contain predominantly rabbit and carrion, with invertebrates present when abundant. These findings were not strictly representative of the diet of foxes in the study area, where rabbits were scarce. Foxes scavenged heavily on lamb carcasses within the study site. The quantity of fresh lamb carrion removed from a lambing paddock in winter 1996 was estimated to support 13-24 foxes, with available fresh lamb theoretically able to support 240-440 foxes. Density based on removal of fresh carcasses was estimated to be 0.83-1.5 foxes/km².

Full textAbstract:
Spicers Creek catchment is located approximately 400 km west of Sydney in the Central West region of New South Wales, Australia. Dryland salinity has been recognised as a major environmental issue impacting soil and water resources in the Central West region of NSW for over 70 years. Due to the geological complexity of the catchment and the presence of high salt loads contained within the soils, groundwater and surface waters, the Spicers Creek catchment was identified as a large contributor of salinity to the Macquarie River catchment. Over fifty-two dryland salinity occurrences have been identified in the Spicers Creek catchment and it appears that dryland salinity is controlled by the presence of geological structures and permeability contrasts in the shallow aquifer system. Combinations of climatic, geological and agricultural factors are escalating salinity problems in the catchment. The main aim of this thesis was to identify the factors affecting salinisation processes in the Spicers Creek catchment. These include the role of geological structures, the source(s) of salts to the groundwater system and the geochemical processes influencing seepage zone development. To achieve these aims a multidisciplinary approach was untaken to understand the soils, geology, hydrogeology and hydrogeochemistry of the catchment. Investigative techniques employed in this project include the use of geophysics, soil chemistry, soil spectroscopy, hydrogeochemistry and environmental isotopes. Evaluation of high-resolution airborne magnetics data showed a major north-east to south-west trending shear zone. This structure dissects the catchment and several other minor faults were observed to be splays off this major structure. These structures were found to be conducive to groundwater flow and are influencing the groundwater chemistry in the fractured aquifer system. Two distinctive groundwater chemical types were identified in the catchment; the saline Na(Mg)-Cl-rich groundwaters associated with the fractured Oakdale Formation and the Na-HCO3-rich groundwaters associated with the intermediate groundwater system. The groundwater chemistry of other deep groundwaters in the catchment appears to be due to mixing between these end-member groundwaters within the fractured bedrock system. The spatial distribution of electrical conductivity, Cl-, Sr2+ and 87Sr/86Sr isotopic ratios showed the correlation between saline groundwaters and the location of faults. Elevated salinities were associated with the location of two crosscutting fault zones. The spatial distribution of HCO3-, K+, Li+ and ?????3CDIC highlighted the extent of Na-HCO3-rich groundwaters in the catchment and showed that these groundwaters are mixing further east than previously envisaged. These findings show that Na(Mg)-Cl-rich groundwaters are geochemically distinctive and have evolved due to extensive water-rock interaction processes within the fracture zones of the Oakdale Formation. These saline groundwaters contain elevated concentrations of trace elements such as As, V and Se, which pose a potential risk for water resources in the area. 87Sr/86Sr isotopic ratios indicated that the source of salinity to the Na(Mg)-Cl-rich groundwaters was not purely from marine or aerosol input. Salt is most likely contributed from various allochthonous and autochthonous sources. This research found that the main mechanism controlling the formation of dryland salinity seepage zones in the Spicers Creek catchment is due to the presence of geological structures. These groundwater seepage zones act as mixing zones for rainfall recharge and deeper groundwaters. The main sources of salt to the seepage zones are from deeper Na(Mg)-Cl-rich groundwaters and rainfall accession. The major importance of this research highlights the need for an integrated approach for the use of various geoscientific techniques in dryland salinity research within geologically complex environments.

Full textAbstract:
Doctor of Philosophy(PhD)The European red fox (Vulpes vulpes L.) is a well known predator of native species and domestic stock, and is recognised as one of Australia’s most devastating vertebrate pests. Current fox management relies heavily on poisoning using baits impregnated with sodium monofluoroacetate (1080). This reliance on 1080 is likely to continue given the lack of viable alternatives for controlling foxes, so that, in the meanwhile, it is important to improve the efficiency of the current techniques. Factors affecting the susceptibility of individual foxes to bait include their ability to locate it, as well as the bait’s palatability and toxicity. The economic costs associated with using different bait types, the pattern and density of their distribution will also affect the efficiency of control programs. It is essential to examine and refine all such issues to ensure efficient use of the 1080 baiting technique. This thesis focuses generally on problems associated with management of the fox in eastern Australia. More specifically, I investigate the factors affecting the efficiency of fox baiting practices on the central tablelands of New South Wales. The study was conducted largely on agricultural lands near the town of Molong (33010’ 37”S, 148087’15”E) on the central tablelands of New South Wales. This area was chosen as it is broadly representative, in terms of land use, of a large region of eastern Australia. The highly modified, predominantly agricultural landscapes near Molong are well suited to foxes, and conflict with the predominantly pastoral community means that fox management is widely undertaken. I determined the persistence of 1080 in two commonly used bait types, Foxoff® and chicken wingettes, under different climatic and rainfall conditions. The rate of 1080 degradation did not change significantly between the central tablelands and the relatively hotter and drier western slopes. Foxoff® baits remained lethal for longer than wingettes under all conditions, although their rate of degradation generally increased with increasing rainfall. I confirmed the presence of defluorinating micro-organisms in thesoils of eastern Australia for the first time, and suggest that, following removal from the bait, 1080 would not persist in the environment for long. Bait should be attractive and highly palatable to ensure that the target species will find and consume it upon discovery. Caching, where discovered food is removed but not immediately consumed, may potentially reduce the efficacy and cost-effectiveness of baiting campaigns. I quantified the caching of chicken wingette, day-old chick and Foxoff® baits by inserting transmitters into bait material and assessing whether it was eaten or cached following removal. The intensity of caching did not change significantly between seasons. Type of bait had the largest influence on caching intensity, with a greater percentage of non-toxic Foxoff® baits (66.9%) being cached than either wingettes (5.7%) or day-old chicks (4.5%). The percentage of toxic (1080) baits cached was even greater, suggesting that 1080 bait may be less palatable, and detectable to foxes. I also investigated the use of conditioned taste aversion to reduce multiple bait uptake by foxes. Levamisole, an illness-inducing chemical, was added to bait and the fate of removed bait was again monitored via radio-telemetry. Following consumption of a levamisole-treated bait, foxes avoided eating treated baits but consumed untreated baits. I concluded that a reduction in bait consumption was achieved through learned aversion to levamisole rather than via conditioned taste aversion to baits. Adding levamisole to baits, especially non-toxic bait such as rabies vaccines, could potentially be used to reduce bait monopolisation by individual foxes. Fox density and den site preferences were assessed by investigating the distribution and density of fox natal dens on one property (9.6 km2) over three consecutive years. A total of 9 natal dens were located in 2000 and 2001, declining to 6 in 2002. No preference was shown for den sites on the basis of habitat, slope or aspect, but more dens were located under, or adjacent to cover. Assuming that each natal den represents a breeding pair and that the population sex ratio did not differ from parity (1:1), the site contained a prebreeding density of 1.9 foxes/km2 in 2000 and 2001, and 1.25 foxes/km2 in 2002. Given that the mean number of cubs is 4.0, the post-breeding density was estimated at 5.6 and 3.75 foxes/km2 in 2000/2001 and 2002, respectively. The results demonstrated that high densities of foxes occur on agricultural lands. The success and likely accuracy of the technique to monitor fox density suggests that it may be used to calibrate more efficient abundance estimates that will be essential for the strategic management of foxes in future. Pest animal management strategies are traditionally assessed for their effectiveness, with less consideration being given to the efficiency or cost of achieving the desired effect. I used cost-effectiveness analyses to compare between different baiting strategies based on the longevity, palatability and handling/replacement costs associated with each bait type. The results indicated that, when measured on a total cost-per-bait-consumed basis, wingettes and day-old chicks were the most cost-effective baits for campaigns of up to 4 weeks duration. This demonstrates the importance of including the longevity, and particularly the palatability of bait, when assessing cost-effectiveness. However, it is recognised that other factors, including the consistency of dosage and uptake by nontarget species, may be equally or more important in deciding the appropriate baiting strategy. The spatial and temporal application of fox baiting in the region overseen by the Molong Rural Lands Protection Board was examined between January 1998 and December 2002 as a case study to evaluate the apparent effectiveness of cooperative management practices. Most landholders (78.8%) did not bait for foxes during this period. Based on known dispersal distances, the effect of fox immigration into baited areas was determined. The results indicated that no areas baited for foxes were separated by a sufficient buffer distance (>9.58 km) from unbaited areas to be protected from fox immigration. This suggests that, at current levels of coordination, the effectiveness of most baiting operations in eastern Australia is compromised over the long term by fox immigration. However, it is recognised that short-term reductions in fox density may sometimes be all that are required to reduce predation to acceptable levels, especially for seasonally-susceptible prey. Ultimately, the cost-effectiveness of control should be evaluated in terms of the response of the prey rather than that of the predator. This study has highlighted deficiencies in current ‘best-practice’ baiting techniques. Specific recommendations for current baiting practices, in addition to future research, are also given. In brief, these include minimising free-feed baiting, increasing the minimum distance between bait stations, and, where possible, presenting the most palatable bait. Continued research into conditioned taste aversion, aerial baiting, and techniques to reduce caching are recommended as potential techniques to improve the efficiency of baiting practices.

Full textAbstract:
Densities and behaviour of Noisy Friarbirds Philemon corniculatus and Red Wattlebirds Anthochaera carunculata were measured during 1992 and 1993 at six sites along an east-west transect through central New South Wales from the Central Coast through to the Central Western Slopes, and at Goobang National Park from 1993 to 1996. Both P. corniculatus and A. carunculata were found to be mostly canopy foragers with occasional forays into the shrub layer when food resources became available there. Flower-probing and foliage gleaning comprised the bulk of foraging behaviour. Most of the food resources used by these honeyeaters were seasonally unreliable and unpredictable, so that they needed to shift between foods and track them over hundreds of kilometres. A strong relationship was found between the densities of honeyeaters and the density of flowering trees at both regional and local scales. Sites on the western slopes were more important for nectar during winter and spring, while sites on the tablelands provided a greater diversity of foods over all seasons. When foraging at foliage, both honeyeaters were found to preferentially select Eucalyptus punctata. These two honeyeaters are very mobile and appear to cope within the fragmented landscape. Their ecological role as plant pollinators, seed dispersers and insect population limiters may have increased proportionally due to habitat fragmentation compared with less mobile species with similar ecological roles. Hence they may also have become more important in maintaining habitat patch qualityDoctor of Philosophy (PhD)

Full textAbstract:
Abstract Aragonite is a minor secondary mineral in many limestone caves throughout the world. It has been claimed that it is the second-most common cave mineral after calcite (Hill & Forti 1997). Aragonite occurs as a secondary mineral in the vadose zone of some caves in New South Wales. Aragonite is unstable in fresh water and usually reverts to calcite, but it is actively depositing in some NSW caves. A review of current literature on the cave aragonite problem showed that chemical inhibitors to calcite deposition assist in the precipitation of calcium carbonate as aragonite instead of calcite. Chemical inhibitors work by physically blocking the positions on the calcite crystal lattice which would have otherwise allowed calcite to develop into a larger crystal. Often an inhibitor for calcite has no effect on the aragonite crystal lattice, thus aragonite may deposit where calcite deposition is inhibited. Another association with aragonite in some NSW caves appears to be high evaporation rates allowing calcite, aragonite and vaterite to deposit. Vaterite is another unstable polymorph of calcium carbonate, which reverts to aragonite and calcite over time. Vaterite, aragonite and calcite were found together in cave sediments in areas with low humidity in Wollondilly Cave, Wombeyan. Several factors were found to be associated with the deposition of aragonite instead of calcite speleothems in NSW caves. They included the presence of ferroan dolomite, calcite-inhibitors (in particular ions of magnesium, manganese, phosphate, sulfate and heavy metals), and both air movement and humidity. Aragonite deposits in several NSW caves were examined to determine whether the material is or is not aragonite. Substrates to the aragonite were examined, as was the nature of the bedrock. The work concentrated on Contact Cave and Wiburds Lake Cave at Jenolan, Sigma Cave, Wollondilly Cave and Cow Pit at Wombeyan and Piano Cave and Deep Hole (Cave) at Walli. Comparisons are made with other caves. The study sites are all located in Palaeozoic rocks within the Lachlan Fold Belt tectonic region. Two of the sites, Jenolan and Wombeyan, are close to the western edge of the Sydney Basin. The third site, Walli, is close to a warm spring. The physical, climatic, chemical and mineralogical influences on calcium carbonate deposition in the caves were investigated. Where cave maps were unavailable, they were prepared on site as part of the study. %At Jenolan Caves, Contact Cave and Wiburds Lake Cave were examined in detail, %and other sites were compared with these. Contact Cave is located near the eastern boundary of the Late Silurian Jenolan Caves Limestone, in an area of steeply bedded and partially dolomitised limestone very close to its eastern boundary with the Jenolan volcanics. Aragonite in Contact Cave is precipitated on the ceiling as anthodites, helictites and coatings. The substrate for the aragonite is porous, altered, dolomitised limestone which is wedged apart by aragonite crystals. Aragonite deposition in Contact Cave is associated with a concentration of calcite-inhibiting ions, mainly minerals containing ions of magnesium, manganese and to a lesser extent, phosphates. Aragonite, dolomite and rhodochrosite are being actively deposited where these minerals are present. Calcite is being deposited where minerals containing magnesium ions are not present. The inhibitors appear to be mobilised by fresh water entering the cave as seepage along the steep bedding and jointing. During winter, cold dry air pooling in the lower part of the cave may concentrate minerals by evaporation and is most likely associated with the ``popcorn line'' seen in the cave. Wiburds Lake Cave is located near the western boundary of the Jenolan Caves Limestone, very close to its faulted western boundary with Ordovician cherts. Aragonite at Wiburds Lake Cave is associated with weathered pyritic dolomitised limestone, an altered, dolomitised mafic dyke in a fault shear zone, and also with bat guano minerals. Aragonite speleothems include a spathite, cavity fills, vughs, surface coatings and anthodites. Calcite occurs in small quantities at the aragonite sites. Calcite-inhibitors associated with aragonite include ions of magnesium, manganese and sulfate. Phosphate is significant in some areas. Low humidity is significant in two areas. Other sites briefly examined at Jenolan include Glass Cave, Mammoth Cave, Spider Cave and the show caves. Aragonite in Glass Cave may be associated with both weathering of dolomitised limestone (resulting in anthodites) and with bat guano (resulting in small cryptic forms). Aragonite in the show caves, and possibly in Mammoth and Spider Cave is associated with weathering of pyritic dolomitised limestone. Wombeyan Caves are developed in saccharoidal marble, metamorphosed Silurian Wombeyan Caves Limestone. Three sites were examined in detail at Wombeyan Caves: Sigma Cave, Wollondilly Cave and Cow Pit (a steep sided doline with a dark zone). Sigma Cave is close to the south east boundary of the Wombeyan marble, close to its unconformable boundary with effusive hypersthene porphyry and intrusive gabbro, and contains some unmarmorised limestone. Aragonite occurs mainly in a canyon at the southern extremity of the cave and in some other sites. In Sigma Cave, aragonite deposition is mainly associated with minerals containing calcite-inhibitors, as well as some air movement in the cave. Calcite-inhibitors at Sigma Cave include ions of magnesium, manganese, sulfate and phosphate (possibly bat origin), partly from bedrock veins and partly from breakdown of minerals in sediments sourced from mafic igneous rocks. Substrates to aragonite speleothems include corroded speleothem, bedrock, ochres, mud and clastics. There is air movement at times in the canyon, it has higher levels of CO2 than other parts of the cave and humidity is high. Air movement may assist in the rapid exchange of CO2 at speleothem surfaces. Wollondilly Cave is located in the eastern part of the Wombeyan marble. At Wollondilly Cave, anthodites and helictites were seen in an inaccessible area of the cave. Paramorphs of calcite after aragonite were found at Jacobs Ladder and the Pantheon. Aragonite at Star Chamber is associated with huntite and hydromagnesite. In The Loft, speleothem corrosion is characteristic of bat guano deposits. Aragonite, vaterite and calcite were detected in surface coatings in this area. Air movement between the two entrances of this cave has a drying effect which may serve to concentrate minerals by evaporation in some parts of the cave. The presence of vaterite and aragonite in fluffy coatings infers that vaterite may be inverting to aragonite. Calcite-inhibitors in the sediments include ions of phosphate, sulphate, magnesium and manganese. Cave sediment includes material sourced from detrital mafic rocks. Cow Pit is located near Wollondilly Cave, and cave W43 is located near the northern boundary of the Wombeyan marble. At Cow Pit, paramorphs of calcite after aragonite occur in the walls as spheroids with minor huntite. Aragonite is a minor mineral in white wall coatings and red phosphatic sediments with minor hydromagnesite and huntite. At cave W43, aragonite was detected in the base of a coralloid speleothem. Paramorphs of calcite after aragonite were observed in the same speleothem. Dolomite in the bedrock may be a source of magnesium-rich minerals at cave W43. Walli Caves are developed in the massive Belubula Limestone of the Ordovician Cliefden Caves Limestone Subgroup (Barrajin Group). At the caves, the limestone is steeply bedded and contains chert nodules with dolomite inclusions. Gypsum and barite occur in veins in the limestone. At Walli Caves, Piano Cave and Deep Hole (Deep Cave) were examined for aragonite. Gypsum occurs both as a surface coating and as fine selenite needles on chert nodules in areas with low humidity in the caves. Aragonite at Walli caves was associated with vein minerals and coatings containing calcite-inhibitors and, in some areas, low humidity. Calcite-inhibitors include sulfate (mostly as gypsum), magnesium, manganese and barium. Other caves which contain aragonite are mentioned. Although these were not major study sites, sufficient information is available on them to make a preliminary assessment as to why they may contain aragonite. These other caves include Flying Fortress Cave and the B4-5 Extension at Bungonia near Goulburn, and Wyanbene Cave south of Braidwood. Aragonite deposition at Bungonia has some similarities with that at Jenolan in that dolomitisation of the bedrock has occurred, and the bedding or jointing is steep allowing seepage of water into the cave, with possible oxidation of pyrite. Aragonite is also associated with a mafic dyke. Wyanbene cave features some bedrock dolomitisation, and also features low grade ore bodies which include several known calcite-inhibitors. Aragonite appears to be associated with both features. Finally, brief notes are made of aragonite-like speleothems at Colong Caves (between Jenolan and Wombeyan), a cave at Jaunter (west of Jenolan) and Wellington (240\,km NW of Sydney).

Full textAbstract:
Glenbrook Lagoon, an 8 hectare lake receiving rainfall runoff from a residential catchment, is experiencing nutrient enrichment problems expressed as excessive aquatic plant presence. This study aims to assess the relative nutrient contribution of the total system compartments, including catchment loading, water column, aquatic plants and surface sediment. This information is utilised in the formulation of management strategies which may produce a sustainable nutrient reduction and general improvement in the system. The total nutrient content of the aquatic system was determined to be high in comparison with the present nutrient loading from the catchment. The ideal management case considers nutrient reduction of the surface sediment compartment firstly, followed by the aquatic plant community, with the water column and catchment influence as relatively low priority compartments. Various strategies for managing these are proposed. The total system benefits of the ideal management case are reductions in nutrients, aquatic plant biovolume and suspended solid loading. Unavoidable constraints placed upon the ideal management case include the excessive aquatic plant presence restricting accessability to the surface sediment for dredging. The resulting best management case requires aquatic plant eradication prior to sediment management, with the total system benefits associated with the ideal management case being retained.Master of Science (Hons)

Full textAbstract:
Over the last 60 years, grass tetany has been recognised as a significant lethal condition in sheep and cattle.Outcomes from this study include documentation of the likely precursors to grass tetany, ways to recognise these precursors, and long term practices that will enable producers to minimise livestock deaths. The benefit of this research to beef producers is that the environmental circumstances thought to be associated with outbreaks of grass tetany have been identified, along with remedial action that can be taken to prevent deaths occurring.Recommendations to industry on best practice to be adopted by leading producers to minimise outbreaks of grass tetany are made.This study provides an alternate strategy for the management of grass tetany in beef cattle, to the more clinical approaches previously recommended. It is suggested that losses from this economically important metabolic disease can be minimised if management practices of beef cattle producers in eastern Australia can incorporate a more holistic approach to farm management, which takes account of the soil/plant/animal/climate inter-relationships.Master of Science (Hons)

Full textAbstract:
In the years between 1960 and 1975 in NSW there emerged a loosely connected network of women interested in modern or creative embroidery. The Embroiderers' Guild of NSW served as a focus for many of these women, providing opportunities for them to exhibit their work, and to engage in embroidery education as teachers or as learners. Others worked independently, exhibited in commercial galleries and endeavoured to establish reputations as professional artists. Some of these women were trained artists and wanted embroidery to be seen as 'art'; others were enthusiastic amateurs, engaged in embroidery as a form of 'serious leisure'. They played a significant role in the development of creative embroidery and textile art in NSW and yet, for the most part, their story is absent from the narratives of Australian art and craft history. These women were involved in a network of interactions which displayed many of the characteristics of more organised art worlds, as posite d by sociologist Howard Becker. They produced work according to shared conventions, they established co-operative links with each other and with other organisations, they organised educational opportunities to encourage others to take up creative embroidery and they mounted exhibitions to facilitate engagement with a public audience. Although their absence from the literature suggests that they operated in isolation, my research indicates that there were many points of contact between the embroidery world, the broader craft world and the fine art community in NSW. This thesis examines the context in which creative embroiderers worked, discusses the careers of key individuals working at this time, explores the interactions between them, and evaluates the influence that they had on later practice in embroidery and textiles in NSW.

Full textAbstract:
Doctor of Philosophy (PhD)Injuries to people living and working on farms in New South Wales continue to be a significant burden on the health system, Workers’ Compensation system, agricultural industries and farming families. Strategies to reduce the number and severity of injuries suffered by farmers and people working on farms rely on accurate information. Unfortunately there is no one dataset available to describe the circumstances surrounding farm injuries and the size of this burden in Australia. Hence, a number of different data sources are required to provide a picture of farm injuries. To date, there has been very little critical examination of what value each of these datasets provides to describing farm injuries. This Thesis aimed to: • Undertake surveillance of injuries occurring to people on farms or during agricultural production in NSW using data from an Emergency Department, NSW Hospital Separations information, NSW Workers’ Compensation Claims, and ABS Deaths data. • Critically examine the utility of Emergency Department, Hospital, Workers’ Compensation, and ABS Deaths Data for the surveillance of farm injuries in NSW. • Critically examine data classification systems used in Emergency Department, Hospital, Workers’ Compensation, and ABS Deaths data collections to describe the breadth of farm injuries in NSW. • Define the priority areas for farm injury prevention initiatives in NSW based on the information obtained from the examination of the data from Emergency Department, Hospital, Workers’ Compensation, and ABS Deaths. • Evaluate the effectiveness of the NSW Rollover Protective Structure (ROPS) rebate scheme and examine the utility of the data currently available in NSW to measure the performance of the program. Four datasets, Tamworth Emergency Department, Hospital Separations, Workers’ Compensation and the Australian Bureau of Statistics (ABS) Deaths data were used to provide information on the surveillance of farm injuries, describe the breadth of classifications used to describe farm injuries, and define priorities for the prevention of farm injuries. There were 384 farm-related injuries which presented to the Emergency Department at the Tamworth Base Hospital between 1 September 1997 and 31 August 1998. Emergency Department data collected in this study used the Farm Injury Optimal Dataset (FIOD) for classification, which allowed for a comprehensive picture of the circumstances surrounding the injury event. The three most common external causes of injury were related to horses, motorcycles, and animals. Commonly people were working at the time of injury. Children represented 21% of the people injured. The average number of injuries per 100 farms per annum was 34.7. An examination of hospital discharge data for NSW was undertaken for the period 1 July 1992 to 30 June 2000 where the location of the injury was a farm. Classification of cases in this dataset conformed to the International Classification of Disease (ICD) versions 9 and 10. There were 14,490 people who were injured on a farm during the study period. The three most common external causes of injury were motorcycles, animals being ridden and agricultural machinery. Children represented 17% of all farm injury cases. The rate per 1,000 farms ranged from 19 to 42 per annum. An examination of Workers’ Compensation claims for agricultural industries in NSW between 1 July 1992 and 30 June 2001 was undertaken. The ‘Type of Occurrence’ classification system was used to code the claims. There were 24,332 claims of which the majority were males (82%). The incidence of injury / disease in agriculture per annum varied from 37 per 1,000 workers to 73 per 1,000 workers. The rate per 1,000 agricultural establishments varied from 54 to 76. The average cost of a claim was $10,880 and the average time lost per claims was 9.2 weeks. There were 81 deaths and 3,158 permanent disabilities. The three most common agents were sheep / goats (5%), ferrous and non-ferrous metals (5%), crates / cartons / boxes / etc (5%). Using ABS deaths data to examine the deaths of people working and living on farms was limited to males whose occupation was recorded as ‘farmer and farm manager’ and ‘agricultural labourer and related worker’. There were 952 deaths over the period 1 January 1991 and 31 December 2000. The information provided a consistent series of cases over time. Areas where prevention should be directed included motor vehicle accidents; falls; agricultural machinery; other machinery; firearms; poisoning; and drowning. Using any one of the datasets alone to examine people injured on farms not only underestimates the number of people injured, but also misses particular types of agents involved in farm injuries. Each of the datasets used in this Thesis provides a different perspective of farm injury in NSW. By examining the information together, there are a number of areas which are consistently represented in each dataset such as falls and agricultural machinery. While no one dataset provided all the information that would be useful for the prevention of injuries, the available information does provide direction for the development of prevention strategies. The overall weakness of the information provided is that it misses a number of risk factors that contribute to farm injuries such as fatigue and training. The lack of appropriate denominator information also makes it difficult to directly compare the datasets and estimate the size of the problem. There are a number of additional coding categories that could be included in each dataset that would provide a better understanding of the different groups at risk of sustaining an injury on a farm or during agricultural work. These coding categories include activity at time of injury, admission to hospital, and occupation. An example of the use of data to determine the effectiveness of a farm injury prevention program is the ‘NSW Rollover Protective Structure (ROPS) Rebate Scheme’ evaluation. Tractor rollover deaths have been identified as an issue for prevention by Farmsafe Australia; however, such deaths were not identified in any of the datasets used in this Thesis due to coding limitations in the ABS data. In this Thesis information about the evaluation of the ‘NSW ROPS Rebate Scheme’ is presented. The scheme was successful in fitting 10,449 ROPS to tractors and the following lessons were learnt: when providing a rebate, the administration (i.e. sending the cheque) needs to be done well; advertising is important and should be co-ordinated, increase the awareness of the risk(s) the intervention is aiming to prevent and effectiveness of subsequent solution (s); the program should ensure there is an increased awareness of the outcome the intervention is aiming to prevent; if regulation is part of the program, enforcement needs to undertaken; and should address any barriers to uptake. The information provided in this Thesis highlights the substantial burden that farm injury places on the agricultural and rural sector of NSW. While there is no one data source that can describe the circumstances and the burden of farm injuries, the currently available datasets do provide an insight into the circumstances of farm injuries and the burden these injuries place on health, Workers’ Compensation, agricultural industries and farming families.

Doctor of PhilosophyResponsible Government began in New South Wales in 1856. Direct participation by women began 70 years later in 1925 with the election of Millicent Preston-Stanley. Her first speech questioned whether Parliament was a fit place for women. Another significant milestone was reached after another 70 years when female MLAs in the Fifty-first Parliament constituted 15% of the Legislative Assembly and female MLCs made up 33% of the Legislative Council. In the 1990s there was no formal barrier to the participation of persons on the basis of their sex but no scholarly study had addressed the question of whether the Parliament’s culture was open to all gender orientations. This study examines the hypothesis that the Parliament informally favoured some types of gender behaviour over others. It identifies ‘gender’ as behaviour rather than a characteristic of persons and avoids the conflation of gender with sex, and particularly with women exclusively. The research used interviews, observation and document study for triangulation. The thesis describes the specific context of New South Wales parliamentary politics 1995-1999 with an emphasis on factors that affect an understanding of gender. It explores notions of representation held by MPs, analyses their personal backgrounds and reports on gender-rich behaviours in the chambers. The study concludes that gender was a significant factor in the behaviour of Members of the Parliament. There were important differences between the ways that male and female MPs approached their roles. Analysis of the concept of gender in the Parliament shows that some behaviours are more likely to bring political success than are others. The methodology developed here by adapting literature from other systems has important strengths. The data suggest that there is a need for many more detailed studies of aspects of gender in parliaments.

Full textAbstract:
This thesis examines mortality rates among adults who experienced full-time imprisonment in New South Wales between January 1988 and December 2002, by record linkage to the Australian National Death Index. The cohort included 76383 men and 8820 women. Over a mean follow-up of 7.7 years, 5137 deaths (4724 men, 423 women) were identified. Three hundred and three deaths (295 men, eight women) occurred in custody. The median age at death was 36.6 years for men and 32.7 years for women. The prominent causes of death were drug overdose, suicide, accidental and cardiovascular disease. The crude mortality rate was 797 per 100000 person-years for men and 685 per 100000 person-years for women. Risk of mortality was 3.7 times greater in male and 7.8 times greater in female prisoners than the standard population. The excess mortality was substantially raised following release from prison in both men (standardised mortality ratio 4.0 vs 1.7) and women (standardised mortality ratio 8.2 vs 2.1). The period of highest risk of death was the first two weeks after release. Drug overdose was the main cause of death, responsible for 68% of the deaths in the first two weeks for men and for 90% of the deaths in this period for women. In men, there was also a clustering of suicide directly after release. Prisoners admitted to prison psychiatric hospital, repeat offenders and those in the early stage of followup were at increased risk of mortality. Violent offenders were overrepresented in suicide figures and property offenders in death from overdose. Minority groups, in particular men, had a lower risk of death than white people. The above findings reinforce how disadvantaged prisoners are, measured by mortality as the most fundamental scale of human wellbeing. Prison represents a potential opportunity for treatment and public health intervention to address some of the health problems underlying the high mortality found in this study. The key challenge is, however, to provide a continuum of care between the prison and community.

Full textAbstract:
This research conducts a conceptual and qualitative investigation into the practices, rationales and functions of imprisonment in NSW. A specific system of imprisonment, in this case the prisons operated by the NSW Department of Corrective services, is explored in order to examine the practices, processes and justifications for incarceration. The various purposes, theories, rhetorics, practices and contradictions of the prison system in NSW and the ways in which the people who are responsible for the administration of this system make sense of its operations and its incoherencies, are central to this analysis. This research utilises a hybrid methodology involving aspects of content analysis and grounded theory. At the centre of this research are eight interviews with senior NSW Corrective Services staff. This analysis is supplemented by interview with ex-prisoners, and other people familiar with, but not working for Corrective Services. In addition a documentary analysis of both Corrective Services documents, and external literature examining NSW prison is carried out. The findings of these analyses are then explored with reference to both their internal coherency, as well as their relationship to a range of theoretical frameworks. The thesis connects abstract and philosophical questions of punishment and penalty with the logistics of running the prison system in NSW. This research found a diversity of practices, understandings and justifications of imprisonment which connected to particular cultural, social philosophical and structural trends. These included victimary discourses, the rhetoric of progress, the influence of managerialism, the faith in ???objective??? professionals, the increasing emphasis on empiricism, the conflicts between coercive practices and individual responsibility, the construction of prisoners as dangerous, and an ongoing struggle for purpose. Imprisonment in NSW was found to be characterised by discrepancies between the intentions of its administrators and pragmatics of its practice, conflicts between internal explanations of its purpose, as well as contradictions between internal Corrective Services accounts and external expectations about the roles, functions and practices of imprisonment. Theoretical perspectives explaining why these characterise imprisonment in NSW were developed. These perspective include the ???ought/is??? confusion of penal administrators, the inhumanity of humane containment, the myth of technocratic amorality, and the sedimentation of purpose.

Geomorphology, archaeology and geoarchaeology: introduction and background -- Surface stone artefact scatters: why can we see them? -- Geomorphic controls on spatial patterning of the surface stone artefact record -- A temporal framework for interpreting surface artefact scatters in Western NSW -- Synthesis: stone artefact scatters in a dynamic landscape.
Surface scatters of stone artefacts are the most ubiquitous feature of the Australian Aboriginal archaeological record, yet the most underutilized by archaeologists in developing models of Aboriginal prehistory. Among the many reasons for this are the lack of understanding of geomorphic processes that have exposed them, and the lack of a suitable chronological framework for investigating Aboriginal 'use of place'. This thesis addresses both of these issues. -- In arid western NSW, erosion and deposition accelerated as a result of the introduction of sheep grazing in the mid 1800s has resulted in exposure of artefact scatters in some areas, burial in others, and complete removal in those parts of the landscape subject to concentrated flood flows. The result is a patchwork of artefact scatters exhibiting various degrees of preservation, exposure and visibility. My research at Stud Creek, in Sturt National Park in far western NSW, develops artefact and landscape survey protocols to accommodate this dynamic geomorphic setting. A sampling strategy stratified on the basis of landscape morphodynamics is presented that allows archaeologists to target areas of maximum artefact exposure and minimum post-discard disturbance. Differential artefact visibility at the time of the survey is accommodated by incorporating measures of surface cover which quantify the effects of various ephemeral environmental processes, such as deposition of sediments, vegetation growth, and bioturbation, on artefact count. -- While surface stone artefact scatters lack the stratigraphy usually considered necessary for establishing the timing of Aboriginal occupation, a combination of radiocarbon determinations on associated heat-retainer ovens, and stratigraphic analysis and dating of the valley fills which underlie the scatters, allows a two-stage chronology for huntergatherer activity to be developed. In the Stud Creek study area, dating of the valley fill by OSL established a maximum age of 2,040±100 y for surface artefact scatters. The heatretainer ovens ranged in age from 1630±30 y BP to 220±55 y BP. Bayesian statistical analysis of the sample of 28 radiocarbon determinations supported the notion, already established from analysis of the artefacts, that the Stud Creek valley was occupied intermittently for short durations over a relatively long period of time, rather than intensively occupied at any one time. Furthermore, a gap in oven building between about 800 and 1100 years ago was evident. Environmental explanations for this gap are explored, but the paiaeoenvironmental record for this part of the Australian arid zone is too sparse and too coarse to provide explanations of human behaviour on time scales of just a few hundred years. -- Having established a model for Stud Creek of episodic landscape change throughout the late Pleistocene and Holocene, right up to European contact, its veracity was evaluated in a pilot study at another location within the region. The length of the archaeological record preserved in three geomorphically distinct locations at Fowlers Gap, 250 km south of Stud Creek, is a function of geomorphic dynamics, with a record of a few hundred years from sites located on channel margins and low terraces, and the longest record thus far of around 5,000 years from high terrace surfaces more remote from active channel incision. But even here, the record is not continuous, and like Stud Creek, the gaps are interpreted to indicate that Aboriginal people moved into and out of these places intermittently throughout the mid to late Holocene. -- I conclude that episodic nonequilibrium characterizes the geomorphic history of these arid landscapes, with impacts on the preservation of the archaeological record. Dating of both archaeological and landform features shows that the landscape, and the archaeological record it preserves, are both spatially and temporally disjointed. Models of Aboriginal hunter-gatherer behaviour and settlement patterns must take account of these discontinuities in an archaeological record that is controlled by geomorphic activity. -- I propose a new geoarchaeological framework for landscape-based studies of surface artefact scatters that incorporates geomorphic analysis and dating of landscapes, as well as tool typology, into the interpretation of spatial and temporal patterns of Aboriginal huntergatherer 'use of place'.

Full textAbstract:
This sociological investigation examines the changing role of parents in the education of their children in Catholic schools in New South Wales over the twentieth century. Catholic Church documents specifically state primary parental responsibility for their children???s religious education. Catholic schools were established to inculcate faith, and assist parents??? role. This thesis asks, to what extent that role has been realised? It unravels the processes that determined and defined the changing role of Catholic parents during this period, and identifies significant shifts in institutional thinking and practices related to parents and resultant shifts in cultural and social perceptions. After half a century of conformity and comfort, a significant era followed as the Australian Church responded to challenges, including financial crisis for Catholic schools, reform in the Australian education system, and the impact of the Second Vatican Council. Cohorts from three generations were selected. Interviews and focus groups elicited memories that were recorded and analysed, in terms of the integral questions; the role and involvement of parents in Catholic schools. Participants recalled their own childhood in Catholic schools and, where applicable, as parents educating their own children, or as religious teachers. The analysis was theoretically informed by the work of Durkheim, Greeley, Coleman and Bourdieu. A review of Church documents and commentaries through the twentieth century, bearing on the education of children, showed the official Church position. Despite numerous rhetorical statements issued by Catholic authorities, emphasising the role of parents as ???primary educators???, the practical responses ranged from active encouragement to dismissal. Teachers in Catholic schools and related bureaucracies were, seemingly, reluctant to initiate a more inclusive partnership role. Gradually, and in a piecemeal fashion, the Catholic Church and its schools have been responding to growing parental consciousness of their role and responsibilities. A significant shift was signalled by the New South Wales Bishops in establishing the Council of Catholic School Parents, to be supported by a full-time, salaried Executive Officer, in 2003. But any accommodation to new understandings of parent/teacher, or family/school relation is complex and not to be oversimplified as a simple sharing, or ceding of authority.

This thesis examines cancer and mortality rates among people diagnosed with hepatitis B (HBV) and C (HCV) infection in New South Wales (NSW) from 1990 through 2002, by linking hepatitis notifications with the NSW Central Cancer Registry (CCR) and National Death Index. Of the 39101 HBV, 75834 HCV and 2604 HBV/HCV co-infection notifications included 1052, 1761 and 85 were linked to cancer notifications and 1233, 4008 and 186 were linked to death notifications respectively. Of 2072 hepatocellular carcinoma (HCC) notifications to the CCR 323, 267 and 85 were linked to HBV, HCV and HBV/HCV co-infection notifications. Incidence of HCC was 6.5, 4.0 and 5.9 per 1000 person years for HBV, HCV and HBV/HCV co-infected groups. Risk of HCC in those diagnosed with hepatitis was 20 to 30 times greater than the standard population. There was a marginally statistically significant increased risk of immunoproliferative malignancies associated with HCV infection (SIR=5.6 95% CI 1.8 ???17.5). Risk of death for those with hepatitis was significantly greater, 1.5 to 5 fold, than the general population with the greatest risk among those with HBV/HCV co-infection. The primary cause of HBV deaths was liver related, particularly HCC, whereas in the HCV groups drug related deaths were most frequent. Among people with HCV, risk of dying from drug related causes was significantly greater than from liver related causes (p=0.012), with the greatest increased risk in females age 15- 24 years (SMR 56.9, 95%CI 39.2???79.9). Median age at diagnosis of HCC varied markedly by country of birth and hepatitis group: HBV 66, 63 and 57years ; HCV 51, 68 and 71 years; unlinked 69, 70 and 64 years for Australian, European, and Asian-born groups, respectively (P<0.0001 for all groups). While the risk of cancer, particularly HCC, is elevated among people with HBV and HCV infection, the absolute risk remains low. Young people with HCV face a higher mortality risk from continued drug use than from liver damage related to their HCV infection. The influence of IDU in the epidemiology of HCC in New South Wales was possibly reflected in the varying distributions of age and country of birth.

Full textAbstract:
Intertidal wetland habitats in southeastern Australia have changed significantly during the past sixty years. Mangrove habitats have expanded both seawards and landwards, the latter being at the expense of saltmarsh habitats. This relatively common phenomenon is generally suggested to be an outcome of sea-level rise. Several factors potentially responsible for this change are examined, including changes in mean sealevel during the past 50 to 100 years, changes in climate, population growth, catchment landuse, and estuary type. A protocol for mapping estuarine habitats was developed and implemented, incorporating the application of geographic information systems. Spatial and temporal coastal wetland habitat changes at nine sites along the New South Wales coast are illustrated. These habitat dynamics were shown to not correlate between sites. The results demonstrate that sea-level rise in this region cannot solely account for the extent of change during the past sixty years. With the exception of one site (Careel Bay), there have been no correlations between contemporary mean sea-level rise and mangrove incursion of the saltmarsh habitats at the study sites, or with rainfall patterns, at the scale of observation in this study, which was largely decadal. The only correlations determined during this study have been between population growth and coastal wetland habitat dynamics in some sites. In spite of saltmarsh habitat loss being a regional phenomenon, local factors appear to have a profound bearing on the rates of change. Neither contemporary mean sea-level rise, rainfall patterns, estuary type, catchment landuse, catchment natural cover nor population pressure can account solely for the patterns in the spatial and temporal dynamics of the coastal wetlands of New South Wales. It seems apparent that regional factors create preconditions favourable for mangrove incursion, but that localised conditions have been responsible for the extent of these incursions from site to site. That is, despite higher sea-level and greater rainfall, the extent of change has been determined by the unique characteristics of each site. The results have important implications for current estuary management practices in the state of New South Wales. The lack of spatial and temporal trends in coastal wetland habitat dynamics point to the need for management to be conducted on a localised, rather than regional scale. Additionally, anthropogenic influences must be carefully managed, since the extent of mangrove habitat expansion into saltmarsh areas is unlikely to be a natural occurrence.

Full textAbstract:
The decline and extinction of amphibian species over the past three decades is widely acknowledged as one of the greatest biodiversity crises of modem time. Providing convincing data to support hypotheses about these declines has proved difficult, which has greatly restricted the development and implementation of management actions that may prevent further amphibian declines and extinctions from occurring. In this thesis, I present research that was undertaken as part of the recovery programs for the southern corroboree frog (Pseudophryne corroboree), and the Booroolong frog (Litoria booroolongensis); two species that underwent very rapid declines in distribution and abundance during the 1980's. More specifically, I investigated potential causal factors in the declines of both species using experimental and correlative studies, and examined the mechanisms by which one threatening process (chytridiomycosis) may be causing continued decline and extinction in P. corroboree. I also examined the implications of population dynamics for monitoring L. booroolongensis, and suggest a possible monitoring strategy that may reliably facilitate the implementation of recovery objectives for this species. I also tested one possible reintroduction technique aimed at preventing the continued decline and extinction of P. corroboree populations.
In Chapters 2 and 3, I present the results from a series of experiments in artificial enclosures designed to examine whether the tadpoles of L. booroolongensis are susceptible to predation by co-occurring introduced predatory fish species; brown trout (Salmo trutta), rainbow trout (Oncorhynchus mykiss), European carp (Cyprinus carpio), redfin perch (Percafluviatilis), and mosquito fish (Gambusia holbrooki). I demonstrated that the tadpoles of L. booroolongensis, and a closely related species Litoria lesueuri, were palatable to non-native trout species, but not to two native predatory fish species, Gadopsis bispinosus and Galaxias olidus. A pond breeding frog species included in this experiment, Limnodynastes tasmaniensis, was palatable to both the native and non-native fish species. In a separate experiment I also demonstrated that the tadpole of L. booroolongensis is palatable to the three other introduced fish species examined in this study; C. carpio, P. fluviatilis, and G. holbrooki. In three of the experiments, the provision of rock within enclosures as a potential refuge habitat did not afford protection to L. booroolongensis tadpoles from
predation by any of the five introduced fish species examined. While all the introduced fish species tested here did consume L. booroolongensis tadpoles, the results also suggested that chemical unpalatability might afford some level of protection against some of these fish species. Firstly, the addition of alternative prey items in one of the experiments reduced the proportion of tadpoles consumed, suggesting that L. booroolongensis may not be a preferred prey item. Secondly, the proportion of tadpoles consumed varied greatly among the different fish species examined, suggesting differing levels of palatability. Overall, this study supports previous research in suggesting that chemical unpalatability may be an important strategy for the tadpoles of riverine frog species in south-eastern Australia to avoid predation by native fish species, and that this strategy is less effective against introduced fish species. While L. booroolongensis currently persists in streams inhabited by a number of introduced fish species, this study supports the likelihood that these species are having a negative impact on populations of L. booroolongensis in the wild.
In Chapter 4, I present the results of a study aimed at examining potential monitoring techniques for L. booroolongensis. The results of a mark-recapture exercise demonstrated that L. booroolongensis may exhibit large fluctuations in abundance from one year to the next, and through a prospective power analysis approach, I demonstrated that it would be difficult to confidently identify population trends of interest using either indices or estimates of abundance for this species. An assessment of the capacity to identify the presence or absence of L. booroolongensis using nighttime
spotlight surveys demonstrated the high detectability of this species using this technique, at both the scale of 300-meter sections of stream and individual breeding areas (typically less than 10-meters of stream). This study suggests that the monitoring objectives of the L. booroolongensis recovery program would be most effectively achieved using presence/absence surveys at different scales.
In Chapter 5, I present the results of a field survey aimed at determining the current distribution and habitat requirements of L. booroolongensis in the South West Slopes region of New South Wales. Of the 163 sites I surveyed across 49 streams,I located
L. booroolongensis along 77 of these sites from 27 streams. Based on population and habitat connectivity, this study identified 18 populations of L. booroolongensis that
are likely to be operating as independent populations. Twelve of these populations are not represented in conservation reserves, but rather occur along streams that flow through the agricultural landscape. A broad scale habitat analysis identified a positive relationship between extent of rock structures along the stream and the occurrence of
L. booroolongensis, and a negative relationship between the proportion of canopy cover and this species' occurrence. At the breeding habitat scale, this study identified a positive relationship between the presence of breeding males and; number of rock crevices in the aquatic environment, extent of emergent rocks, and proportion pool. This analysis also detected a negative relationship between occupancy and water depth. These results confirm previous work suggesting the importance of rocky stream habitats to the persistence of L. booroolongensis, but also suggest how disturbance processes, such as increasing sedimentation and weed invasion, may reduce the suitability of rocky structures as breeding sites.
In Chapter 6, I investigated current levels of amphibian chytrid fungus (Batrachochytrium dendrobatidis) infection in corroboree frog populations, and used retrospective screening of museum specimens to assess the possibility that this pathogen was implicated in the initial decline of the corroboree frogs. Using histology, I did not detect any B. dendrobatidis infections in corroboree frog populations prior to their decline, however using the same technique, moderate levels of infection were detected in post-decline populations of both species. Real-time PCR screening of skin swabs identified much higher overall infection rates in post-decline populations of P. corroboree (between 44% and 59%), while significantly lower rates of infection were observed in P. pengilleyi populations (14%). These results suggest that the initial and continued decline of the corroboree frogs may well be attributed to the emergence of B. dendrobatidis in populations of these species.
In Chapter 7, I investigated how B. dendrobatidis may be causing the continued decline of P. corroboree through the presence of an abundant reservoir host for this pathogen. I found that populations of adult C. signifera in sub-alpine bogs carry high
B. dendrobatidis infection rates (86%), but appear unaffected by this infection. An experiment involving the release of P. corroboree tadpoles into 15 natural pools resulted in metamorphs from seven of these pools testing positive for B. dendrobatidis, with all these individuals dying soon after metamorphosis. These
results support the possibility that B. dendrobatidis infection in P. corroboree populations is being facilitated by the presence of large numbers of infected C. signifera in the shared environment.
Chapter 8 presents the results of a population augmentation study for P. corroboree. I investigated the extent to which increasing recruitment to metamorphosis may result in population recovery in this species. This was undertaken by harvesting eggs from the field and rearing them through to mid stage tadpoles over the winter period prior to being released back to their natal ponds in spring. While I was able to increase recruitment to metamorphosis by an average of 20 percent, this did not result in a noticeable influence on the subsequent adult population size, as both manipulated and non-manipulated sites declined over the course of this study by an average of 80 percent. I observed a positive relationship between natural recruitment to a late tadpole stage and subsequent adult male population size, however there was considerable variation associated with this relationship. The relationship between recruitment and subsequent population size at the augmentation sites was consistent with the relationship observed at the non-manipulated sites. These results suggest that recruitment to metamorphosis may not be the most important life stage restricting the population recovery of P. corroboree, but that mortality during post-metamorphic stages may be more important in regulating current population size. Hence, further attempts to use captive rearing to increase P. corroboree populations in the wild should focus on the release of post-metamorphic frogs.
Overall, this thesis demonstrates the value of quantitative research to the implementation and progress of threatened species recovery programs. While this research will specifically contribute to the recovery programs for L. booroolongensis
and P. corroboree, it more broadly contributes to the understanding and capacity to respond to the concerning levels of amphibian extinctions currently occurring throughout the world.

Full textAbstract:
In response to concern that excessive macroalgal growth and accumulation was occurring in some inshore areas of Lake Macquarie, the distribution, abundance and seasonality of macroalgae was investigated in relation to nutrient input and power station cooling water. Macroalgal dry weight biomass was measured at ten sites on a monthly basis for two years, with an analysis of community structure conducted using Multi-Dimensional Scaling. The macroalgal community in Lake Macquarie was typical of those found in other New South Wales coastal lagoons, exhibiting considerable spatial and temporal variation. A close similarity was observed in macroalgal community structure at sites affected by urban nutrient input, these being characterised by a high biomass often attributable to only one or two species. These nuisance macroalgae were mostly green algae, which were almost entirely absent from other sites. Biomass at sites affected by urban nutrient input was generally within the range documented for eutrophic estuaries elsewhere. Analysis of macroalgal community structure showed no evidence of large-scale changes macroalgal communities attributable to the effects of power station cooling water except within 500m of the outfall. At sites affected by a 1-2??C temperature increase, community structure and the magnitude of the biomass were similar to sites deemed as being relatively free of human impact. A reduction in species diversity occurred only within the immediate discharge zone, where water temperatures were approximately 6??C above ambient temperatures. Excessive growth of nuisance macroalgal species was not observed at any of the sites influenced by power station cooling water. There were no distinct patterns in seasonality of macroalgal growth in this study, though the greatest biomass appeared to occur in spring. The irregular temporal variation in macroalgal growth suggests that the most significant factors affecting growth occur on a time scale of weeks to months. It is therefore likely nutrient input to the nearshore through surface runoff is an important influence on the distribution and abundance of macroalgae in Lake Macquarie. This emphasises the need to reduce nitrogen and phosphorus input from urban sources in Lake management.

Full textAbstract:
Throughout their world distribution, fruit bats (Chiroptera: Pteropodidae) play an extremely
important role in forest ecology through seed dispersal and pollination. However, the
recognition of their role in maintaining forest ecological diversity has been largely
overshadowed by the fact that fruit bats are known to cause damage to a wide variety of
cultivated fruits and, as a result, significant effort is undertaken to control fruit bat numbers
in areas where crop damage frequently occurs.
In Australia, fruit bats of the genus Pteropus (or flying foxes) are well known for their role
in destroying valuable fruit crops, particularly along the east coast from Cairns to Sydney.
Historical evidence suggests that flying foxes have been culled as an orchard pest in large
numbers for the past 80 years. Uncontrolled culling both on-farm and in roosts coupled
with extensive habitat destruction in the past century, has resulted in noticeable declines
both in flying fox distribution and local population numbers.
In New South Wales, flying foxes have been 'protected' under the National Parks and
Wildlife Act (1974) since 1986. From that time, fruitgrowers have been required to obtain
a licence (referred to as an occupier's licence) from the National Parks and Wildlife Service
(NPWS) to cull flying foxes causing damage to fruit crops. However, despite the
'protected' status of the species, flying foxes continue to be culled in large numbers as an
orchard pest.
An examination of the management of flying foxes in NSW, has shown that, between
1986-1992, fifteen NSW National Parks and Wildlife Service Districts issued a combined
total of 616 occupier's licences to shoot flying foxes with an total allocation of over
240,000 animals. In addition, most flying foxes are culled when the female is carrying her
young under wing or when the young remain in the camp but continue to be dependent on
her return for survival. Further evidence on the extent of culling includes a widely
distributed fruitgrower survey with responses indicating that as few as 50% of the
fruitgrowers shooting flying foxes in NSW obtain the required licence from the National
Parks and Wildlife Service.
While the NPWS has undertaken research into the role of flying foxes in seed dispersal and
pollination, management effort largely continues to focus on resolving conflicts between
fruitgrowers and flying foxes primarily by issuing culling permits to fruitgrowers. At
present, there is no NPWS policy on the management of flying foxes in NSW to guide the
administration of the permit system. As a result, the process of issuing permits for flying
foxes is largely inconsistent between NPWS Districts.
The absence of comprehensive goals and objectives for the management of flying foxes has
resulted in the current situation where large numbers of flying foxes are being culled both
legally and illegally in the absence of any data on the impacts of unknown culling levels on
local flying fox populations.
The NPWS has a statutory obligation to manage flying foxes consistent with the 'protected'
status of the species in NSW and several well known principles of wildlife management.
However, current management of flying foxes in indicates that the Service may be in
violation of the requirement to 'protect' and 'conserve' flying foxes as required under the
National Parks and Wildlife Act (1974).
This study recommends that licences issued to fruitgrowers to cull flying foxes be
discontinued immediately and that adequate enforcement be engaged to reduce illegal
shooting. This action should continue until such time that research on flying fox
populations is able to demonstrate that the culling of flying foxes will not lead populations
into decline. Furthermore, management effort should focus on the development of
alternative strategies to reduce crop damage by flying foxes and provide incentives for
growers to utilize existing control strategies such as netting.

Full textAbstract:
Duchenne muscular dystrophy (DMD) is an X-linked lethal condition associated with high morbidity and mortality. There is currently no cure for this disease. Several gene-based therapeutic approaches for treating DMD are currently under development but all are dependent on the knowledge of the causative dystrophin gene mutation. A combined mutation detection approach consisting of a quantitative PCR based analysis and DNA sequencing of the dystrophin gene resulted in a mutation etection rate of 96% in the New South Wales (NSW) DMD cohort. The proportion of exon duplication mutations was twice that generally reported for similar patient opulations. The clinical utility of the combined mutation protocol for DMD carrier testing clarified the carrier status of an additional one-third (33%) of female relatives compared to a conventional approach of biochemical, pedigree and linkage studies. The generally accepted view that two-thirds of mothers of isolated cases of DMD are themselves mutation carriers is challenged. Although this assumption is valid for duplication and DNA sequence mutations, it is not valid for deletion mutations in the NSW cohort. The incidence of new cases of DMD in the New South Wales population was educed from approximately 1 in 3594 live male births to 1 in 6022 live male births over a 25 year period, indicative of a significant effect of the combination of genetic counselling and improved methods of carrier detection over that period. In a study of a cohort of boys with DMD, who had both psychological and mutational analysis, it was shown that mutations affecting the shorter, C-terminal isoforms of dystrophin are associated with decreased mean intellectual function. A hypothesis is presented that mutations within the long 5' untranslated region of the Dp140 isoform are unlikely to significantly affect expression of this brain-expressed isoform. During the course of studying the NSW DMD cohort a family was identified which exhibited X-linkage and a unique clinical presentation involving episodes of severe and prolonged muscle weakness. A novel variant in the pyruvate dehydrogenase E1 alpha subunit (PDHA 1) was identified. The phenotypic effect of this variant is not proven but a body of evidence implicates this as likely to be causative of the observed phenotype.

Full textAbstract:
Master of Philosophy in Public HealthThis thesis is about the substantial service Karitane provided in the teaching of mothercraft to guide parents in the care of their young children in New South Wales. At first called the Australian Mothercraft Society, it emerged in New South Wales as a voluntary organisation in 1923, closely allied to New Zealand’s Plunket Society founded in 1907 by Sir Truby King. Karitane was at its most active in the 1940s when it provided over a quarter of Sydney’s residential mothercraft services. Its beginnings were overshadowed by conflict and the New South Wales Department of Public Health did not acknowledge Karitane until the 1960s. Until then Karitane was absent from the public record of services for mother and baby in NSW. Sydney’s Eastern Suburbs community and the Karitane Products Society in New Zealand supported Karitane before it integrated into New South Wales’ government supported health services. Throughout it delivered on its aims of teaching mothers ways of caring for infants, disseminating knowledge about the care of young children and preparing specialist nurses. The main theme of this thesis is the ‘moving frontier’ that is the boundary between the voluntary providers of health services and governmental provision of health services. Karitane’s development has depended on the politics of health care at Commonwealth, State and local levels. The secondary themes derive from the competition for scarce resources amongst the professional groups involved; doctors, nurses and health service administrators. Karitane’s experience has not been unique; it has followed a trajectory common to voluntary organizations providing personal care services through the twentieth century and it has conformed to trends in public health. Sometimes Karitane led the trends and sometimes it trailed; it adapted to circumstances but it retains a degree of independence. Shining through all the problems with resources are the human experiences of appreciative mothers who used Karitane’s services and the dedicated staff and supporters who provided mothercentred help with the care of infants. The mother/infant relationship continues to be a central concern for public health. This study of Karitane gives a longitudinal perspective on the contribution of a small band of skilled people with a clear mission to provide services to assist mothers with their babies and young children.

Full textAbstract:
Knowledge of the convict period in New South Wales has been substantially expanded and enriched through a number of revisionist scholarly studies in the last quarter of the twentieth century. The cumulative result has been the establishment of a number of new orthodoxies. These studies have drawn on a number of analytic frameworks including feminism and cliometrics, successfully challenging the previous historiography. The rich archival sources in New South Wales have been utilised to reformulate the convict period by a number of scholars, demonstrating the complexity of life in the penal colony. Academic divisions between what are regarded as “Australian” history and “British” history have imposed their own agendas on writing about transportation. This study challenges this imposition through an examination of petitioners’ approaches to the home and colonial administrations. A lacuna in the scholarly studies has been a lack of attention to transportation’s consequences for married couples and their children. This study seeks to narrow that gap through these petitions. The findings of the study demonstrate the continuation of links between those who were transported and those who remained in Britain. It is argued that these findings have important implications for future research within Britain, and that what is disclosed by these petitions and the individuals who were involved in on-going communications cannot be restricted either to Australian or convict histories. Our knowledge of what transportation meant to individuals in the periphery as well as those in the metropole is diminished if the focus remains firmly on the settler community. Supplementary material from contemporary sources as well as the official records passing between the two administrations has been utilised and these supplementary sources suggest that there was a broad division between official publicly stated policy and practice in respect of transportees’ family circumstances. Chapter One establishes the architecture of the thesis and explains the methodology adopted. Chapter Two offers a reinterpretation of the colony’s formation in 1788 and inserts the “convict audience” of that day into the historiography . Chapter Three examines two petitioners writing from different gaols in Britain prior to their expected transportation. A resolution of the division between cliometrics and this more qualitative humanist approach is proposed. Chapter Four is a study of petitioners in Britain and a study of the process required for a reunion and reconstitution of family units in New South Wales. Chapter Five seeks to a resiting of male convicts as family members through an examination of a number of contemporary sources. Chapter Six examines the petitions raised by husbands and fathers for their wives and families to be given free passages to the colony. Chapter Seven provides case studies of three transportees and their experiences of the petitioning process. In Chapter Eight the focus broadens out from married men to examine and provide a revision of convicts’ correspondence with their relatives and friends in Britain. Such correspondence has previously provided the basis for nationalist interpretations; the revision here suggests that such interpretations are anachronistic. Chapter Nine is an extended metaphor drawing the material together to the conclusions of the study.

Full textAbstract:
Elevated arsenic concentrations have been reported in a drinking water and irrigation-supply aquifer of Stuarts Point, New South Wales, Australia. Arsenic occurrence in such aquifers is potentially a major issue due to their common use for high yield domestic and irrigation water supplies. Ten multi-level piezometers were installed to depths of approximately 30 m in the sand and clay aquifer. Sediment samples were collected at specific depths during drilling and analysed for chemical and mineralogical composition, grain size characteristics, potential for arsenic release from solid phase and detailed microscopic features. From this data, a full geomorphic reconstruction allowed the determination of source provenance for the aquifer sediments. The model proposed herein provides evidence that the bulk of the aquifer was deposited under intermittent fluvial and estuarine conditions; and that all sediments derive from the regional arsenicmineralised hinterland. More than 200 groundwater samples were collected and analysed for over 50 variables. The heterogeneity of the aquifer sediments causes redox stratification to occur, which in turn governs arsenic mobility in the groundwater. The bulk of the aquifer is composed of fluvial sand deposits undergoing reductive dissolution of iron oxides. Arsenic adsorbed to iron oxide minerals is released during dissolution but re-adsorbs to other iron oxides present in this part of the aquifer. The deeper, more reducing fluvial sand and estuarine clay groundwaters have undergone complete reductive dissolution of iron oxides resulting in the subsequent mobilisation of arsenic into groundwater. Some of this arsenic has been incorporated into iron sulfide mineral precipitates, forming current arsenian pyrite sinks within the aquifer. The extraction of groundwater from the aquifer for irrigation and drinking water supply induces seawater intrusion of arsenic-rich estuarine water, bringing further dissolved arsenic into the aquifer. A greater understanding of the source, sinks and mobilisation of arsenic in this aquifer contributes to our broad understanding of arsenic in the environment; and allows aquifer specific management procedures and research recommendations to be made. Any coastal or unconsolidated aquifer that has sediments derived from mineralised provenances should consider monitoring for arsenic, and other potentially toxic trace elements, in their groundwater systems.

The problem for the study was to investigate possible systematic semantic variation in linguistic interaction associated with social class locations of speakers, and relations between any such variants and features of interaction in joint book-reading in Kindergarten. -- A preliminary survey of 427 families in two sociogeographically contrasted sites established that joint book-reading was a common social practice, and gave sufficient indications of variation to justify an intensive socio-semantic study. Two sets of ten mother-child dyads, contrasted for class locations using Bernstein's (1990) theory of class relations, were constructed and recordings of joint book-reading sessions made by mothers. Recordings of interaction in two sets of ten Kindergarten classes in the same socio-geographical areas were made by teachers. -- Vygotsky's theory of semiotic mediation was the general resource used for interpreting children's learning, but it was necessary to resolve problems in the theory in the modelling of contexts for learning, and of mediational means. For this purpose the systemic functional linguistic concept of context of situation, as proposed by Halliday (1978) and expanded by Hasan (in press (a)), was deployed. -- Transcripts of recordings were analysed through a semantic network developed for the study, based on a network proposed by Hasan (1983). -- Semantic variation associated with class locations of families was found across all four metafunctions described within systemic theory, and one variant found to be associated with Kindergarten classroom interaction. The variable semantic features were interpreted as the realization of different principles regulating the individuation of experience, using Bernstein's theories of coding orientation and pedagogic discourse.

Full textAbstract:
There is concern that canyoning, which has grown in popularity in recent years, may not be environmentally sustainable within the Blue Mountains National Park. Sociomanagerial research was undertaken, using an initial focus group discussion and subsequent surveys. Canyoners were found to participate in their sport predominantly in small groups in relatively few canyons, were generally experienced, did not feel crowded by other people encountered, and displayed little evidence of displacement behaviour from popular locations. No specific biophysical impacts were perceived as serious. Canyoners generally supported management action to control visitation to canyons if overuse could be demonstrated, with education and/or restrictive actions as preferred management strategies. Biophysical research was undertaken to test a potential rapid assessment bioindicator for measuring and monitoring potential visitor impacts. Macroinvertebrate data were analysed and no significant difference in macroinvertebrate assemblage composition or water quality was found between high and low visitation streams. Macroinvertebrate fauna were found to be highly resilient to trampling. Current visitation levels within the canyons appeared to be within ecologiocally sustainable levels. The implications of the findings are discussed for visitor impact management policymaking.Doctor of Philosophy (PhD)

Full textAbstract:
In rural inland, south-eastern Australia, allergy to the fungus Alternaria is prevalent and an important risk factor for asthma. The aim of the thesis was to investigate the distribution and factors influencing allergens of Alternaria in the air. As airborne allergenic spores were thought to arise from harvesting of nearby crops, two towns with different agricultural practices were studied. Moree has two crop harvesting periods in summer and autumn whilst Wagga Wagga has one harvesting period in summer. Over two years, air was sampled daily in Wagga Wagga and Moree using Burkard traps. The reliability of measurements from a single site to represent the distribution of airborne concentrations of spores across each town was examined using data from three traps simultaneously, sited 2.0 to 4.9 km apart, over four weeks. Substantial intra-class correlation coefficients (ICC) were observed between the three sampling sites across both towns (ICC=0.52, 95% CI 0.30-0.71 to 0.76, 95% CI 0.61-0.87) when counts of Alternaria spores were relatively high. The correlation was poor when counts were low. Of more than 365 trap tapes examined, the two microscopic traverses strongly correlated for counts of Alternaria spores (ICC=0.95, 95% CI 0.94-0.96). Alternaria was detected in both towns throughout the two year period with peaks in spore concentrations reflecting the season of crop harvesting in each region. Individual exposure to spores was examined. Thirty three subjects (adults and children from nine families) wore nasal air samplers and personal air samplers both inside and outside their homes. The effects of activity, location, age on the inhalation of Alternaria spores and variation between individuals in the same environment were determined. Every subject inhaled Alternaria spores. Personal exposure to Alternaria in the home environment varied substantially between subjects. Levels of fungal spores inhaled were higher during periods of activity than during rest, and higher while subjects were outdoors than indoors. During outdoor activity, the number of Alternaria spores inhaled ranged from 4 to 794 (median 11) spores/hr. Sources of airborne spores was investigated by sampling air above wheat and cotton crops near the towns during harvesting and non-harvesting periods, in a grain and cotton seed storage shed, and a cotton gin. Substantially higher concentrations were detected above crops during harvesting periods compared to non-harvesting periods. Peaks were associated with harvesting and other activities where plants were manipulated. By regression analysis spore concentrations in both towns were modelled against those detected above crops and with weather variables. Only one crop sampling period (cotton harvest) independently correlated with concentrations in town. Analysis combining all data showed concentrations of spores above crops correlated with spore concentrations in the town when lagged by one day. Variables of rainfall and maximum temperature influenced concentrations in both towns, and wind direction in Wagga Wagga alone. Parents of asthmatic children were asked by questionnaire in which locations symptoms were provoked. Asthma was reported to be exacerbated at grain farms and with disturbance of local vegetation in town and home gardens. Nasal sampling confirmed that activities that disturbed dust or vegetation increased the inhalation of spores. The factors that release allergen from spores were determined in a modified Halogen immunoassay. Approximately 60% of spores released allergen, and the proportion was influenced by isolate, nutrient availability, viability, and not influenced by sunlight or culture age up to 21 days. Germinating the spores significantly increased the proportion that released total allergen and Alt a 1 (p<0.0001). Alt a 1 appears to be a minor contributor to the total allergen released from spores except when spores have germinated. Conclusions: People living in inland rural regions of Australia are exposed to substantial quantities of allergenic spores of Alternaria. Exposure is a highly personal event and is largely determined by disturbance of local vegetation releasing spores such as from nearby crops by wind, harvesting, slashing, transport and processing of produce, and from within town and home gardens. Most spores inhaled are likely to be allergenic, with potency potentially increasing with viability.

Full textAbstract:
The study area extends from west of the Great Divide to the Broken Hill and Tibooburra regions of far western New South Wales, encompassing several important mining districts that not only include the famous Broken Hill lodes (Pb-Zn-Ag), but also Parkes (Cu-Au), Peak Hill (Au), Cobar (Cu-Au-Zn) and White Cliffs (opal). The area is generally semi-arid to arid undulating to flat terrain covered by sparse vegetation.
¶
During the Cretaceous, an extensive sea retreated across vast plains, with rivers draining from the south and east. After the uplift of the Great Divide associated with opening of the Tasman Sea in the Late Cretaceous, drainage swung to the west, cutting across the Darling River Lineament. The Murray-Darling Basin depression developed as a depocentre during the Paleogene. Climates also underwent dramatic change during the Cenozoic, from warm-humid to cooler, more seasonal climates, to the arid conditions prevalent today. Up until now, there has been very little temporal constraint on the development of this landscape over this time period. This study seeks to address the timing of various weathering and landscape evolution events in northwestern New South Wales.
¶
The application of various regolith dating methods was undertaken. Palaeomagnetic dating, clay δ18O dating, (U+Th)/He and U-Pb dating were all investigated. Palaeomagnetic and clay dating methods have been well established in Australian regolith studies for the last 30 years. More recently, (U+Th)/He dating has been successfully trialled both overseas and in Australia. U-Pb dating of regolith materials has not been undertaken. Each method dates different regolith forming processes and materials. Palaeomagnetic and clay dating were both successfully carried out for sites across northwestern New South Wales, providing a multi-technique approach to resolving the timing of weathering events. Although (U+Th)/He dating was unsuccessful, there is scope for further refinement of the technique, and its application to regolith dating. U-Pb dating was also unsuccessfully applied to late-stage anatase, which is a cement in many Australian silcretes.
¶
Results from this study indicate that the landscape evolution and weathering history of northwestern New South Wales dates back at least 60 million years, probably 100 million years, and perhaps even as far back as 180 million years. The results imply that northwestern New South Wales was continuously sub-aerially exposed for the last 100 Ma, indicating that marine sedimentation in the Murray-Darling and Eromanga-Surat Basins was separated by this exposed region. The ages also provide further evidence for episodic deep chemical weathering under certain climatic conditions across the region, and add to the data from across Australia for similar events. In particular, the palaeomagnetic ages, which cluster at ~60 ± 10 Ma and 15 ± 10 Ma, are recorded in other palaeomagnetic dating studies of Australian regolith. The clay ages are more continuous across the field area, but show older clays in the Eromanga Basin sediments at White Cliffs and Lightning Ridge, Eocene clays in the Cobar region, and Oligocene Miocene clays in the Broken Hill region, indicating progressively younger clay formation from east to west across northwestern New South Wales, in broad agreement with previously published clay weathering ages from around Australia.
¶
These weathering ages can be reconciled with reconstructions of Australian climates from previously published work, which show a cooling trend over the last 40 Ma, following an extended period of high mean annual temperatures in the Paleocene and Eocene. In conjunction with this cooling, total precipitation decreased, and rainfall became more seasonal. The weathering ages fall within periods of wetness (clay formation), the onset of seasonal climate (clay formation and palaeomagnetic weathering ages) and the initiation of aridity in the late Miocene (palaeomagnetic weathering ages).
¶
This study provides initial weathering ages for northwestern New South Wales, and, a broad geochronology for the development of the landscape of the region. Building on the results of this study, there is much scope for further geochronological work in the region.

Full textAbstract:
Doctor of PhilosophyThis thesis is concerned with an examination and re-assessment of the establishment, operation and management of the Female and Male Orphan Schools, in the first half of the nineteenth century in New South Wales. The chaplains and governors in the early penal settlement were faced with a dilemma, as they beheld the number of children who were ‘orphaned’, neglected, abandoned and destitute. In order to understand the reasons why these children were in necessitous circumstances, the thesis seeks to examine the situations of the convict women, who were the mothers of these children. Governors Philip Gidley King and Lachlan Macquarie respectively in 1801 and 1819 established the Schools, which provided elementary education, training and residential care within a religious setting. Researching the motives underlying the actions of these men has been an important part of the thesis. An examination of the social backgrounds of some of the children admitted to these Schools has been undertaken, in order to provide a greater understanding of the conditions under which the children were living prior to their admissions. Information about family situations, and the social problems encountered by parents that led them to place their children in the Schools, have been explored. The avenues open to the girls and boys when they left the Schools, has formed part of the study. Some children were able to be reunited with family members, but the majority of them were apprenticed. A study of the nature of these apprenticeships, has led to a greater understanding of employment opportunities for girls and boys at that time. In 1850 the Schools were amalgamated into the Protestant Orphan School at Parramatta. By examining the governance and operation of the Schools during their last two decades as separate entities, we have more knowledge about and understanding of these two colonial institutions. It is the conclusion of this thesis that some of the harsher judgements of revisionist social historians need to be modified. It was the perception that more social disorder would occur if action was not taken to ‘rescue’ the ‘orphaned’ children, usually of convict parentage. However genuine charity, philanthropy and concern was displayed for the children in grave physical and moral danger. The goals of the founders were not always reached in the Orphan Schools, nevertheless they performed an invaluable service in the lives of many children.

Full textAbstract:
The New South Wales Medical Board established a Health Programme for the assessment and rehabilitation of doctors whose clinical performance was impaired by alcohol or psychoactive substance use, mental or physical illness. This programme was developed to be individualized to the needs of each registrant. The present study has three aims: 1. To describe those doctors who participated in the Board???s Health Programme. 2. To chart the duration of involvement of these doctors through the programme. 3. To examine the outcomes associated with this programme. The study is based on the prospective cohort of all 181 impaired doctors who participated in the Health Programme between July 1st 1993 and April 30th 2001. Information on each registrant was collected at the time of the initial assessment and at each review conducted as part of the programme. Additional qualitative data was also collected and supplemented by a file audit conducted in August and September 2001. One hundred and eighty-one doctors were prospectively monitored as part of this study. The largest source of impairment was psychiatric illness (45.3%), 77% of the doctors were male. The average age of the cohort was 41.6 (sd 11.1) years. Impaired doctors were more likely to be working in emergency medicine or psychiatry and be based in a rural area. Of those who had finished their involvement in the programme, successful graduates participated for a mean of 38.2 (sd 22.3) months. In general outcomes of involvement were positive, 64 of 113 (56.6%) of doctors successfully graduated from the programme. One hundred and ten of 168 (65.5%) improved during the period of their involvement and 111 of 126 (88.1%) were working in medicine. Five, 2.8% of the participants died during the period of this study. Measures of registrant insight and support tended to increase during the period of involvement with the Health Programme. Future studies will need to establish evidence for the most appropriate interventions with impaired doctors. This process would be strengthened by the collection of standardized data across intervention programmes, supplemented with functional assessments and the collection of qualitative data.

Full textAbstract:
Studies were undertaken for estuarine stocking of mulloway Argyrosomus japonicus to develop efficient marking techniques; to identify key habitats and migratory patterns of stocked fish; to evaluate the diet and growth of stocked fish and recruitment to commercial fisheries; and to develop a numerical model to estimate optimal stocking density from the predatory impact of stocked fish. The 10-step responsible approach to marine stock enhancement (Blankenship and Leber 1995) was reviewed for four Australian species, and Argyrosomus japonicus and Lates calcarifer were found to be the best candidates for stocking in Australia. Immersion of mulloway in an oxytetracycline-undiluted seawater solution produced poor quality marks, whilst oxytetracycline-diluted seawater solutions and alizarin complexone-seawater solutions produced high quality marks in otoliths and fin spines. These techniques were applied to produce double marks, and in batch mode at fish densities of 30 kg m-3. Key habitats for mulloway were identified as discrete holes or basins up to 20 m deep. Hatchery-reared fish initially had significantly greater movements (greater than 10 km in 3 d) when released in shallow water, compared to hatchery-reared fish released directly over deep holes. Such targeted release strategies could revolutionise stocking of depleted fisheries in estuarine and aquatic habitats, and even oceans. Stomach content analysis of mulloway captured from a coastal lagoon and riverine estuary revealed ontogenetic changes in major prey of mysid shrimp, prawns and forage fish. Comparison between benthic resources and dietary composition in these two estuaries revealed that mulloway consume prey resources in proportion to those in the environment, and do not actively select prey. Simulations of a novel Predatory Impact Model were run for part of the Georges River Recreational Fishing Haven, Sydney, to evaluate appropriate stocking density and associated predatory impact. The 15 km stretch of the Georges River contained c. 361,000 m2 of key mulloway habitat, and 10% of mysid shrimp production within this habitat was assigned to support stocked fish. Given these values, this section of river could support c. 4,000 stocked 8 cm mulloway. Over the 4 y during which mulloway are resident in the estuary, these fish will have a maximum yearly predatory impact of 6.7 t y-1 forage fish, 1.8 t y-1 school prawns and 2.2 t y-1 cephalopods, which represents 48%, 17% and 127% of former commercial fishery in the Georges River respectively.
