Exploiting synergistic interactions ofMedicago sativaL. andParaburkholderia tropicafor enhanced biodegradation of diesel fuel hydrocarbons
Publisher: Cold Spring Harbor Laboratory
Date: 30-03-2021
DOI: 10.1101/2021.03.30.437699
Abstract: The biotechnological application of microorganisms for rhizoremediation of contaminated sites requires the development of plant-microbe symbionts capable of plant growth promotion and hydrocarbon degradation. Studies focusing on microbial consortia are often difficult to reproduce, thereby necessitating the need for culturable single bacterial species for biotechnological applications. Through genomic analyses and plant growth experiments, we examined the synergistic interactions of Medicago sativa L. and Paraburkholderia tropica for enhanced remediation of diesel fuel-contaminated soils. Comparative genomics revealed strong potential of P. tropica for plant growth-promotion, chemotaxis and motility, root nodulation and colonization, and diesel fuel degradation. Plant growth experiments confirmed that P. tropica thrived in the contaminated soils and effectively enhanced M. sativa growth. Geochemical analysis showed that the M. sativa + P. tropica treatment resulted in an efficient degradation of diesel fuel hydrocarbons within two months, offering great prospects for enhanced biodegradation of organic pollutants.
Corporate governance and financial policies
Publisher: Emerald
Date: 09-03-2015
Abstract: – The purpose of this paper is to examine the influence of board structure on idend policy of Australian corporate firms. It also considers the traditional explanations of corporate idend choice, such as agency cost theory, signalling hypothesis, the life cycle hypothesis along with tax-based explanations of idend policy. – The final s le consists of 413 non-financial firms that are part of the All Ordinaries Index. The causal analysis was undertaken in three stages. In the first stage, the authors analyse the likelihood of paying idends. And classify all firms as either idend payers or non-payers. The authors then model this binary variable as a function of different sets of variables. In the second stage, the authors analyse the factors determining the magnitude of idend payout by those firms that have paid a idend. In contrast, stage three employs all firms – those which did not pay any idend and those firms which paid a idend. – For the study period 2004-2009, this study finds that board independence has a significant positive influence on the idend payout of Australian firms. This finding is consistent with the “outcome” model of La Porta et al. (2000). This study also finds that size has a significant positive influence on the idend payout of Australian firms thus providing support for the agency cost view of idend policy. Similarly, this study also finds support for the signalling hypothesis and the life cycle theory given the significant positive influence of profitability and the significant negative influence of current losses and growth opportunities on the idend policy of Australian firms. – The findings of the study are robust with to alternative measures of variables employed and are not influenced by the global financial crisis. However, this study did not consider the possible endogenous and multiple relationships between idends, debt, profitability, cash holdings and governance structures given the limited study period considered. – This study finds that board independence has a significant positive influence on the idend behaviour of Australian firms. This suggests that idends and independent directors play complementary governance roles. While idends provide the monitoring and disciplinary roles, independent directors act as catalysts for enhancing effective board functioning. These findings have implications for corporate governance policies and the payout policies. – Though the governance role of idends has long been recognized in the literature (Easterbrook, 1984 Jensen, 1986), very few studies analyse the influence of board characteristics on the decision to pay idends in Australia. Given the distinct Australian setting where the tax imputation system allows companies to pay franked idends to domestic investors, this study provides evidence on the interaction of corporate and idend policies. This study finds that idend polices are influenced by percentage franking of idends. This study also finds that board independence has a significant positive influence on the idend policy of Australian firms.
The Potential of Oxygenates to Increase the Risk of Exposure to Polycyclic Aromatic Hydrocarbons through Groundwater Contamination
Publisher: MDPI AG

DOI: 10.3390/W14050739
Abstract: The Clean Air Act (42 U.S. Code § 7401) is one of the United States of America’s most influential environmental laws. Under the Clean Air Act Amendments of 1990, oxygen-containing organic compounds must be added to some fossil fuels with the goal of combating CO2 and particulate emissions. However, one major implication is the effect of co-solvency on the leaching potentials of polycyclic aromatic hydrocarbons (PAHs) into groundwater. Our research investigated this effect on three groups of recalcitrant PAHs that are present in diesel fuel. Our results reveal that ethanol addition enhances the leaching potentials of these otherwise hydrophobic contaminants, with 10% ethanol (E10) resulting in elution of all the PAHs studied. While 5% ethanol addition to diesel fuel resulted in the elution of an average of 2.5% of all the trimethylnaphthalenes and 6.0% of the C2 alkylphenanthrenes present in diesel fuel, 10% ethanol addition led to the elution of more than 80% of each of the studied trimethylnaphthalene peaks and more than 70% of each of the studied C2 alkylphenanthrene peaks present in diesel fuel. In view of the known mutagenic and carcinogenic risks associated with exposure to PAHs through groundwater contamination, our study highlights the need for energy scientists to carefully consider the environmental and health implications of ethanol-blended innovations holistically. It is not enough to save the atmosphere but ruin the hydrosphere and most importantly, human health.

Quantitative Framework for Astrobiology Strategies and in situ Biogenic Assessments

DOI: 10.3389/FSPAS.2022.769607
Abstract: In July 2020, NASA’s Perseverance (Mars 2020) mission was launched. The rover sent to the surface of Mars will not only perform in situ analyses, but will also collect rock and regolith s les that will be returned to Earth by future missions for further investigations. Therefore, the amount and quality of astrobiological data retrieved from these missions is expected to be unprecedented. The challenge faced by the astrobiology community will be to use these data in the most efficient way to assess whether any of the analysed s les are of biogenic origin. However, in situ biogenic assessments often lack quantitative support. Particularly, their statistical uncertainty is not systematically evaluated. This study aims to provide the first quantitative framework that evaluates the uncertainty of in situ biogenic assessments using recursive Bayesian statistics. Our results show that detecting more than seven potential biosignatures does not increase the reliability of biogenic assessments, unless the probability of detection of biosignatures in the s le and the probability of the biosignatures being false positives are well constrained. This study emphasizes the need for quantitative support of biogenic assessments and astrobiology strategies in general.

PYROLYSIS OF AROMATIC COMPOUNDS AS A GUIDE TO SYNTHETIC REACTIONS IN SEDIMENTS
Publisher: CSIRO Publishing
Date: 1994
DOI: 10.1071/AJ93022
Abstract: The syntheses of methylaromatics by the reactions of phenanthrene, anthracene and pyrene with coals and CH4 at 220°C to 400°C is demonstrated. At temperatures not exceeding 350°C the experimental conditions may be thermally equated, in terms of R0 values, to those approximating the oil window. Therefore, the high degree of methylation achieved, the insensitivity of the methylation process to reaction conditions and the systematic and theoretically predictable increases with temperature in the ratio of the ß/α substituted methyl isomers of the parent aromatic hydrocarbon, provide support for significant geosynthetic processes in sediments. The high concentration of n-alkanes generated from the coal may play a crucial role in reactions.

Australian women's experiences of receiving maternity care during the COVID‐19 pandemic: A cross‐sectional national survey
Publisher: Wiley
Date: 27-06-2022
DOI: 10.1111/BIRT.12569
Abstract: The COVID‐19 pandemic has led to multiple changes in maternity services worldwide. Systems rapidly adapted to meet public health requirements aimed at preventing transmission of SARS‐CoV‐2, including quarantine procedures, travel restrictions, border closures, physical distancing and “stay‐at‐home” orders. Although these changes have impacted all stakeholders in maternity services, arguably the women at the center of this care have been most affected. This study aimed to explore women's experiences of receiving maternity care during the COVID‐19 pandemic in Australia. A national cross‐sectional online survey, including fixed choice and open‐ended questions, was conducted during the first wave of the COVID‐19 pandemic in Australia pregnant and postnatal women were recruited through social media networks. The survey was completed by 3364 women. Women felt distressed and alone due to rapid changes to their maternity care. Limited face‐to‐face contact with health practitioners and altered models of care often required women to accommodate significant changes and to coordinate their own care. Women felt that they were often “doing it alone,” due to public health restrictions on support people and visitors, both within and outside health services. Women described some benefits of visitor restrictions, such as, more time for rest, breastfeeding establishment, and bonding with their baby. This large nationwide Australian study provides unique data on women's experiences of receiving maternity care during the COVID‐19 pandemic. Lessons learned provide an opportunity to rebuild and reshape the maternity sector to best meet the needs of women and their families during current and future public health crises.

Abstract: The fuel used for motor-sledging during Scott's 1910–1913 expedition has been reanalysed to assess its suitability for that task in Antarctica. A research octane number of 65 and volatility were low compared with modern fuels but probably suitable when considering the design of the flathead engine. The findings are consistent with view that engine design was the primary cause of the mechanical failings.

No Aladdin's Cave in New South Wales? Local Government Amalgamation, Scale Economies, and Data Envelopment Analysis Specification
Publisher: SAGE Publications
Date: 20-04-2015
Abstract: Local government structural reform programs are often based on the purported benefits of increased scale. We examine this question in relation to the proposed amalgamation program for New South Wales (NSW) by the NSW Independent Local Government Review Panel using Data Envelopment Analysis (DEA). We find evidence that a significant proportion of municipalities scheduled for amalgamation already exceed optimal scale and that the great majority of “amalgamated” entities will initially exhibit decreasing returns to scale. Our findings thus stand in stark contrast to the Independent Local Government Review Panel (ILGRP) contention that municipal mergers are the optimal approach to capturing economies of scale in NSW local government.

Hydrocarbon charge history of the northern Londonderry High
Publisher: CSIRO Publishing
Date: 2001
DOI: 10.1071/AJ00023
Abstract: Re-appraisal of the oil charge history of the northern Londonderry High has identified numerous palaeo-oil columns of up to 80 m in height. An integration of the oil charge history, stress field analysis and contemporary seepage data allows a sub ision of the well results into three distinct provinces. These each have distinct charge histories that reflect differences in potential source kitchens and all have been adversely affected by the Neogene collision of the Australian and Southeast Asian plates. Traps located on the northern and northeastern Londonderry High have experienced high oil charge rates at the Mesozoic level, with nearly all valid traps showing evidence of prior oil accumulation. Breaching of these oil columns in the Neogene appears to be related to the orientation of the contemporary stress field, which promotes shear failure on the faults reliant for seal. Present day hydrocarbon migration indicators, such as Synthetic Aperture Radar (SAR) data show differences in seepage response between the northern and northeastern Londonderry High, with prolific current day seepage restricted to the northern province. Rapid subsidence associated with plate collision has accelerated maturation in the northern province to create these strong seepage anomalies over this region. The absence of seepage over the breached oil columns of the northeastern province indicates that either, oil charge has ceased to this area or that hydrocarbon leakage is episodic in nature.In contrast, results from the northwestern province show no evidence of prior oil accumulation, despite many wells having tested valid traps. These data point to either a lack of connected oil migration pathways or an impoverished source kitchen for liquid hydrocarbons. Low levels of seepage in the northwestern Londonderry High detected by the SAR data are minor compared with other parts of the Timor Sea and consistent with migration continuing at the current day. The overall prospectivity for fault bound traps in the study area appears to be low, due to extensive fault reactivation producing low fault seal integrity. Stratigraphic plays that do not rely on faults for seal, particularly in the northern and northeastern provinces, represent an alternative play concept at the Jurassic level. At shallower levels in the Cretaceous, subtle four-way dip closed structures are often enhanced by the reactivation process and could be ideally positioned to receive remigrated oil from breached Jurassic oil accumulations.

The Use and abuse of fluorescence colours as maturity indicators of oil in inclusions from Australasian petroleum systems
Publisher: CSIRO Publishing
Date: 2001
DOI: 10.1071/AJ00025
Abstract: It is well established that the fluorescence colours of crude oils shift towards the blue end of the spectrum with increased API gravity and implied thermal maturity. Oil inclusions also fluoresce, and it would be useful to correlate these fluorescence colours likewise to thermal maturity, because oil inclusions often contain the only direct evidence of residual oils once present in a reservoir. In order to validate this concept, the geochemical and petrographic properties of fluid inclusion oils in 36 sandstone s les from Australasian oil fields have been compared. A maturity assessment was made for each fluid inclusion oil using 25 molecular maturity ratios. Each fluid inclusion oil was placed in one of four maturity brackets, approximately equivalent to early, mid, peak and post oil generation windows.S les containing mainly blue-fluorescing oil inclusions have thermal maturities throughout the oil window, including relatively low maturities (Rc

Radiocarbon analysis of halophilic microbial lipids from an Australian salt lake

DOI: 10.1016/J.YQRES.2011.10.003
Abstract: Assigning accurate dates to hypersaline sediments opens important terrestrial records of local and regional paleoecologies and paleoclimatology. However, as of yet no conventional method of dating hypersaline systems has been widely adopted. Biomarker, mineralogical, and radiocarbon analyses of sediments and organic extracts from a shallow (13 cm) core from a hypersaline playa, Lake Tyrrell, southeastern Australia, produce a coherent age-depth curve beginning with modern microbial mats and extending to ~ 7500 cal yr BP. These analyses are furthermore used to identify and constrain the timing of the most recent change in hydrological regime at Lake Tyrrell, a shift from a clay deposit to the precipitation of evaporitic sands occurring at some time between ~ 4500 and 7000 yr. These analyses show the potential for widespread dating of hypersaline systems integrating the biomarker approach, reinforce the value of the radiocarbon content of biomarkers in understanding the flow of carbon in modern ecologies, and validate the temporal dimension of data provided by biomarkers when dating late Quaternary sediments.
The Impact of More Intensive Unemployment Benefit Requirements on Jobseekers’ Likelihood of Complying*
Publisher: Wiley
Date: 09-01-2022
Abstract: After 12 months of unemployment, Australian benefit recipients must undertake intensive participation in activities, in addition to standard requirements. Advocacy groups have raised concerns that these requirements are too onerous. If this were the case, those with additional requirements would be expected to comply less, and more often have a valid reason for non‐compliance. We examine this claim using discontinuities in levels of requirements. We do not find evidence of higher rates of non‐compliance or valid reason. However, further research is required to determine how to optimally set requirements, including further research on the efficacy of the requirements themselves.

Diversity and metagenome analysis of a hydrocarbon-degrading bacterial consortium from asphalt lakes located in Wietze, Germany
Publisher: Cold Spring Harbor Laboratory

DOI: 10.1101/2021.03.25.436929
Abstract: The pollution of terrestrial and aquatic environments by petroleum contaminants, especially diesel fuel, is a persistent environmental threat requiring cost-effective and environmentally sensitive remediation approaches. Bioremediation is one such approach, but is dependent on the availability of microorganisms with the necessary metabolic abilities and environmental adaptability. The aim of this study was to examine the microbial community in a petroleum contaminated site, and isolate organisms potentially able to degrade hydrocarbons. Through successive enrichment of soil microorganisms from s les of an historic petroleum contaminated site in Wietze, Germany, we isolated a bacterial consortium using diesel fuel hydrocarbons as sole carbon and energy source. The 16S rRNA gene analysis revealed the dominance of Alphaproteobacteria . We further reconstructed a total of 18 genomes from both the original soil s le and the isolated consortium. The analysis of both the metagenome of the consortium and the reconstructed metagenome-assembled genomes show that the most abundant bacterial genus in the consortium, Acidocella , possess many of the genes required for the degradation of diesel fuel aromatic hydrocarbons, which are often the most toxic component. This can explain why this genus proliferated in all the enrichment cultures. Therefore, this study reveals that the microbial consortium isolated in this study and its dominant genus, Acidocella , could potentially serve as an effective inoculum for the bioremediation of sites polluted with diesel fuel or other organic contaminants.

Overpressure release: Fluid inclusion evidence for a new mechanism for the formation of heavy oil
Publisher: Geological Society of America
Date: 18-05-2020
DOI: 10.1130/G47227.1
Abstract: Heavy oils in sedimentary basins are commonly related to biodegradation and water washing, and thermal degradation of sulfur-rich kerogen at an early hydrocarbon generation stage. However, the potential for overpressure release to form heavy oil has been seldom considered and rarely demonstrated. Paragenetic sequences of diagenetic and oil charge events, pressure-temperature-composition (P-T-x) evolutionary history reconstruction, and molecular geochemical data from a single generation of oil inclusions reveal that heavy shale oil in the PS18–1 well in the Dongpu Depression, Bohai Bay Basin, China, was neither a product of biodegradation nor due to early oil generation during kerogen maturation. Instead, the precipitation and retention of polar compounds of a previously charged, higher-maturity oil from deeper source rocks, induced by intense pressure reduction during basin uplift, represent the most likely mechanism for the formation of the heavy oil. The precipitation of polar compounds during primary and secondary migration due to intense pressure release may be an important mechanism for explaining compositional fractionation effects in the expelled petroleum fluids in source rocks, bitumen, and heavy oil distributions in unconventional shale systems, and deep non-biodegraded heavy oils. This mechanism has wider implications for understanding the hydrocarbon distribution in overpressured basins.

Metagenomic insight into the plant growth-promoting potential of a diesel-degrading bacterial consortium for enhanced rhizoremediation application
Publisher: Cold Spring Harbor Laboratory
Date: 26-03-2021
DOI: 10.1101/2021.03.26.437261
Abstract: The slow rate of natural attenuation of organic pollutants, together with unwanted environmental impacts of traditional remediation strategies, has necessitated the exploration of plant-microbe systems for enhanced bioremediation applications. The identification of microorganisms capable of promoting both plant growth and hydrocarbon degradation is crucial to the success of plant-based remediation techniques. Through successive enrichments of a soil s le from a historic oil-contaminated site in Wietze, Germany, we isolated a plant growth-promoting and hydrocarbon-degrading bacterial consortium. Metagenome analysis of the consortium led to the identification of genes and taxa putatively associated with these processes. The majority of the coding DNA sequences involved in these reactions were affiliated to Acidocella aminolytica and Acidobacterium capsulatum. In microcosm experiments performed in association with Medicago sativa L., the consortium achieved 91% rhizodegradation of diesel fuel hydrocarbons within 60 days, indicating its potential for biotechnological applications in the remediation of sites contaminated by organic pollutants.

Abstract: Phosphate-shelled brachiopods differ in filter-feeding lifestyle, with Lingula anatina an active infaunal burrower, and Discinisca tenuis a shallow marine epibenthic animal. The shells of these animals are built of organophosphatic constituents, the organic fibres/sheets reinforced with calcium phosphate to provide a sophisticated ultrastructural robustness. This investigation examined the nature of the organic fibres in order to improve understanding of how living organisms produce hierarchically structured biomaterials. Unlike powdered s les commonly used in previous studies, organic fibres were isolated for the first time and the shell fractions were purified, in order to study the content and nature of the biopolymer fibres. Biochemical methods including Calcofluor staining revealed a chitin matrix. Ultrastructural analysis, thermal gravimetric analysis, and spectroscopic analyses show that the core polysaccharide framework is composed of layers of β -chitin sheets and/or fibrils that are coated with a fibrous organic matrix. There is more chitin matrix in the L. anatina shells (26.6 wt.%) compared to the D. tenuis shells (12.9 wt.%). Taken together, the data show that the chitin matrix contributes to increased skeletal strength, making L. anatina highly adapted for life as an active burrower. In comparison, D. tenuis contains less chitin and lives as attached epibenthos in a shallow marine environment. First spectroscopic evidence of β-chitin sheets in recent organophosphatic brachiopods
Efficiency measurement of basic service delivery at South African district and local municipalities
Publisher: AOSIS
Date: 04-04-2009
DOI: 10.4102/TD.V5I2.133
Abstract: South Africa has experienced immense changes in the post- apartheid era and coordinated local public policy has sought to expand and improve the level of basic services provided to previously disadvantaged people. Local government has played a pivotal role in this process and has been subjected to intense reform in an effort to enhance its effective- ness and broaden its range of activities. While a number of scholars have examined the administrative, political and social dimensions of the local government reform program, little attention has focused on the economic efficiency of service delivery. This paper seeks to remedy this neglect by evaluating the productive efficiency with which municipal councils have delivered electricity, domestic waste removal, sanitation and water in line with their new responsibilities using Data Envelopment Analysis (DEA) techniques applied to cross-sectional data covering the period 2006/2007 for 231 local municipalities and 46 district municipalities.
An intersectoral comparison of Australian water reforms
Publisher: IWA Publishing
Date: 10-2008
DOI: 10.2166/WP.2007.031
Abstract: Reformation of the policies for allocating Australia's water resources has now assumed profound political, economic and social significance. However, there are marked contrasts between urban and agricultural sectors, in the approach to policy reform. Whereas governments have embarked on a range of mandated initiatives to alter or constrain the behaviour of urban dwellers, the approach adopted for irrigated agriculture has been characterised by an emphasis on markets and private property rights. This paper explores the extent of these disparate and potentially incongruous policies by focussing primarily on the states with the largest irrigation sectors, New South Wales and Victoria. Whilst acknowledging the high transaction costs of in idual households engaging in a water market, the paper argues for more liberal market participation by urban water authorities on behalf of their constituents. The paper also calls for more rigorous economic assessment of the plethora of water-saving and demand-management strategies being proposed in the urban water setting.

Aromatic compound-degrading taxa in an anoxic coal seam microbiome from the Surat Basin, Australia
Publisher: Oxford University Press (OUP)
Date: 31-03-2021
Abstract: Methane is an important energy resource internationally, and a large proportion of this methane is produced by microbial communities living in coal seams. Despite the value of this resource for human energy security, our understanding of the metabolic roles played by specific taxa during the biodegradation of coal to methane in situ is quite limited. In order to develop a greater understanding of microbial catabolism on coal, a community from a coal seam in the Surat Basin, Australia, was incubated on 10 different aromatic organic compounds: coronene, benzo[a]pyrene, pyrene, phenanthrene, naphthalene, ethylbenzene, phenol, benzoate, vanillate and syringate. Each of these aromatic compounds either occurs in coal or is a possible product of the coal biodegradation process. 16S rRNA sequencing revealed substantial changes to each community in response to each aromatic carbon substrate provided. Abundant taxa from these substrate-specific communities were identified and their probable catabolic roles proposed based on literature searches of related taxa. This study is the first to link specific coal seam taxa to aromatic substrates available in coal seam environments. Two conceptual models of the putative degradation pathways and key taxa responsible are proposed.
Evidence for a new oil family in the Nancar Trough area, Timor Sea
Publisher: CSIRO Publishing
Date: 2002
DOI: 10.1071/AJ01021
Abstract: Geochemical evidence is presented for a previously unrecognised oil generative source rock in the Nancar Trough area. This source rock supplements the middle to late Jurassic source rocks, which have previously been shown to have generated most of the oils in the northern Bonaparte Basin and the Vulcan Sub-basin. Fluids with a strong contribution from this new source rock, defined here as the Nancar oil family, have an unusually high abundance of mid-chain substituted monomethylalkanes. In comparison, oils from the Vulcan Sub-basin contain mostly terminally substituted monomethylalkanes and the overall abundance is much lower. Oils from the Laminaria High and some from the northern Vulcan Sub-Basin show intermediate characteristics and may be co-sourced. Evidence from the analysis of fluid inclusion oils was important in establishing the presence of the new oil family because interference from drilling mud contaminants could be excluded. The detailed geochemistry of Ludmilla–1 fluid inclusion oil suggests the source rock for the Nancar oil family was deposited in a marine environment under sub-oxic conditions with limited sulphur content, a low contribution of terrestrial organic matter and a high contribution of organic matter from bacterial activity. Since monomethylalkanes are typical biomarkers of cyanobacteria, the source rock that gave rise to the new oil family may be rich in cyanobacterial organic matter. Further studies on sediment extracts are needed to establish an explicit oil-source rock correlation and to identify the stratigraphic location alaeo-environment of the source rock. Such information will be valuable in determining the prospectivity of the large and relatively unexplored province draining the Nancar Trough kitchen.

Prisoner Taking and Prisoner Killing: A Comment on Ferguson's Political Economy Approach
Publisher: SAGE Publications
Date: 11-2007
Abstract: Niall Ferguson argued that, in part, the Second World War proved much more difficult to end than the First World War because both the German and Japanese armed forces continued fighting long after any realistic prospect of victory had disappeared. He ascribes this difference to the comparatively greater difficulties faced by soldiers wishing to surrender in the Second World War. Only after the Allied military authorities had adopted policies encouraging surrender in the Second World War did large numbers of enemy troops voluntarily surrender, thereby bringing the conflict to a swift conclusion. Ferguson contends that the game theoretic approach developed in economics, as exemplified in the prisoner's dilemma game, can be extended to a `captor's dilemma' game that can shed light on the efficacy of various strategies on surrender policy available to military forces. This paper considers the game theoretic approach advanced by Ferguson and suggests that it requires further refinement before it can satisfactorily explain the problem of surrender.
Cyanobacterial Inhabitation on Archean Rock Surfaces in the Pilbara Craton, Western Australia
Publisher: Mary Ann Liebert Inc
Date: 07-2015
Abstract: High abundances of 7- and 6-monomethylalkanes as well as C17 n-alkane, indicative of cyanobacteria, have been discovered near the surfaces of Archean carbonate rocks of the Fortescue Group in the Pilbara region, Western Australia. The presence of cyanobacterial biomarkers is mostly limited to the surface layer (<1 cm thickness) of the rocks, indicating that the cyanobacteria are an endolithic species. Biomarkers are found in bitumen I (solvent-extracted rock) and also in bitumen II (solvent-extracted decarbonated rock). The abundance of biomarkers is generally the same between both bitumen fractions in the surface layer, which suggests that the cyanobacteria penetrated into the carbonate minerals. Trace amounts of the biomarkers have also diffused into a deeper part of the rocks, but this influence is only seen in bitumen I. This implies that hydrocarbons moved toward the inside of the rock through pores and fissures in the rock fabric. In contrast, hydrocarbons in bitumen II, which mainly come from within the carbonate minerals, are isolated from the hydrocarbon migration from the outside of the rock and may be ancient indigenous organic matter. To the best of our knowledge, this is the first report of the past or modern inhabitation of cyanobacteria on Archean rocks in the Pilbara region for which hydrocarbon biomarker analyses was used.

An efficiency analysis of basic service provision in South African local government (2006/7 to 2008/9)
Publisher: AOSIS
Date: 31-12-2012
DOI: 10.4102/TD.V8I2.232
Abstract: The South African local government sector has undergone changes in the post-apartheid era as policy makers have sought to improve basic services provided to disadvantaged local communities. While scholars have considered various dimensions of the reform program, little effort has been directed at evaluating the effectiveness and efficiency dimensions of the changes in service provision, with some notable exceptions (van der Westhuizen and Dollery, 2009 Krugell, et al., 2010). This article seeks to contribute to this literature by evaluating the efficiency with which municipalities have provided (Reconstruction and Development Program) RDP water, RDP sanitation RDP electricity and RDP refuse removal, using Data Envelopment Analysis techniques (DEA) applied to panel data from 2006/2007 to 2008/2009 for 231 local municipalities and 46 district municipalities.Keywords: Data warehousing, Systems thinking, Prescriptive theory, Descriptive theory, Interpretative research.

An Empirical Analysis of International Migrant Business Ownership and Employment in Regional Australia*
Publisher: Wiley
Date: 28-04-2022
Abstract: A broad consensus exists that Australian economic activity is too heavily concentrated in capital cities, and regional employment creation should be encouraged. Given the magnitude of international migration to Australia, it is important to determine the impact of migration on regional development by investigating business ownership and job creation by international migrants in regional areas. This paper examines the probability that regional migrant business owners are employers – and thereby employment generators – using a multivariate logit model. We find that migrant business owners with staff are more likely to be male, married and live in regional NSW, metropolitan Victoria and regional and metropolitan Queensland.

Economies of Scale and Local Government Expenditure: Evidence From Australia
Publisher: SAGE Publications
Date: 17-12-2012
Abstract: Controversy surrounds structural reform in local government, especially efforts aimed at involuntarily reducing the number of local authorities to secure scale economies. We examined whether scale economies exist in local government outlays by analyzing the expenditure of 152 New South Wales councils. Initially, council expenditure is characterized by scale economies. However, given the correlation between population and population density, it is important to determine whether the influence of population on expenditure is due to variations in population density. When areas are decomposed into subgroups on the basis of density, the evidence of scale economies largely disappears.

The influence of vegetation and soil properties on springtail communities in a diesel-contaminated soil
Publisher: Elsevier BV
Date: 04-2018
DOI: 10.1016/J.SCITOTENV.2017.11.186
Abstract: Soil health is important for the functioning of all terrestrial ecosystems, but may be impacted by contamination. Soil contamination may in turn necessitate rehabilitation and remediation works, but many of the techniques currently used cause physical disturbance to the soil structure, which may in itself affect soil assemblages. An understanding of the relative influence of these two types of disturbance on soil biota is needed to inform in situ remediation activities. Subantarctic Macquarie Island provides an ideal location to study these interactions because soil bio ersity is naturally low and a number of diesel spills have undergone active in situ remediation in recent years. In this study, soil cores were collected in triplicate from 21 locations. Springtails were extracted and identified to genus/species level. Total petroleum hydrocarbon (TPH) concentrations were measured at the surface and at 0.5m depth at each site, as was vegetation coverage and a range of soil properties. The relationships between these data were examined using distance-based linear models. Together, all environmental variables (vegetation and soil properties) explained a total of 76% of the variation in springtail assemblages. Soil properties alone accounted for 52% of the variation in springtail assemblages, of which bulk density was most important followed by soil conductivity and pH. Vegetation cover by the four plant taxa accounted for 34% of variation observed, with Leptinella plumosa and Poa foliosa having the greatest influence. Surface and underlying TPH concentration did not have a significant effect on springtail assemblages. Overall, factors that can be linked to physical soil disturbance had greater influence over springtail assemblages than did soil contamination. This finding may influence the selection of the most appropriate contaminant management approach for environmentally sensitive sites.

Integrating heavy-mineral, geochemical and biomarker analyses of Plio-Pleistocene sandy and silty turbidites: a novel approach for provenance studies (Indus Fan, IODP Expedition 355)
Publisher: Cambridge University Press (CUP)
Date: 14-08-2019
DOI: 10.1017/S0016756819000773
Abstract: A multidisciplinary mineralogical, geochemical and biomarker study of Indus Fan sediments cored during International Ocean Discovery Program (IODP) Expedition 355 to the Laxmi Basin was carried out to define the different compositional signatures of sand, silt and clay. Upper Pliocene – lower Pleistocene turbidites from sites U1456 and U1457 were selected as the best candidates for this study. The integrated dataset presented here was obtained by coupling traditional and innovative bulk-sediment and single-mineral techniques on the same s les. Turbiditic deposits mostly consist of medium to fine silt, including rich and erse heavy-mineral assemblages. Such a fine grain size forced us to push the limits of high-resolution quantitative heavy-mineral analysis down to as low as 5 μm. Heavy-mineral analysis allowed us to establish a Himalayan origin of the detritus in the studied turbidites. Heavy-mineral concentrations are higher in channel-fill than in overbank deposits. Mineralogical and geochemical data concur in revealing that fast-settling ultradense minerals such as zircon are preferentially concentrated in channel-fill deposits, whereas the top of overbank deposits are notably enriched with slow-settling platy phyllosilicates. Biomarker analysis represents a most suitable complementary technique that is able to investigate the provenance signature of the finer sediment fraction, largely consisting of clay. This technique allowed us to identify a largely terrigenous origin of organic matter at Site U1456 and an open marine origin at Site U1457. The latter site lies closer to the Laxmi Ridge, where thermal maturity increases with depth to reach the early oil window (127°C at c . 320 m below the seafloor).

DOI: 10.1038/S43247-022-00526-2
Abstract: The biotechnological application of microorganisms for rhizoremediation of contaminated sites requires the development of plant-microbe symbionts capable of plant growth promotion and hydrocarbon degradation. Here, we present a study aimed at isolating single microbial strains that are capable of promoting plant growth as well as rhizoremediation of diesel fuel hydrocarbons. Through genomic analyses and greenhouse-based experiments, we examined the synergistic interactions of Medicago sativa L. and Paraburkholderia tropica WTPI1 for enhanced rhizoremediation of diesel fuel-contaminated soils. Plant growth-based experiments confirmed that the inoculation of M. sativa with P. tropica led to a 99% increase in plant biomass. Furthermore, organic geochemical analysis revealed that 96% of all the distinctive diesel fuel hydrocarbons, including C 10 –C 25 n -alkanes, branched alkanes, cycloalkanes and aromatic hydrocarbons were degraded in the M. sativa + P. tropica treatment. These results will prove beneficial for biotechnological application of P. tropica WTPI1 for plant growth promotion and most importantly for environmental remediation of organic pollutants.

An Evaluation of the Financial Sustainability of Remote Australian Local Councils*
Publisher: Wiley
Date: 25-03-2022
Abstract: Spatial remoteness in the sense of great distances between population centres and limited access to public services is an on‐going problem in Australian local government, where there exist large, sparsely populated regions dominated by the 'tyranny of distance'. From a public policy perspective, it is important to understand the impact of remoteness on local authorities. Accordingly, in this paper, we estimate the relationship between remoteness and financial sustainability using a 2014–2018 s le of Australian local governments. In general, we find only limited empirical evidence for a relationship between geographical remoteness and financial sustainability as we have proxied it.

Methanogenic archaea in subsurface coal seams are biogeographically distinct: an analysis of metagenomically‐derived mcrA sequences
Publisher: Wiley
Date: 10-05-2022
Abstract: The production of methane as an end‐product of organic matter degradation in the absence of other terminal electron acceptors is common, and has often been studied in environments such as animal guts, soils and wetlands due to its potency as a greenhouse gas. To date, however, the study of the biogeographic distribution of methanogens across coal seam environments has been minimal. Here, we show that coal seams are host to a erse range of methanogens, which are distinctive to each geological basin. Based on comparisons to close relatives from other methanogenic environments, the dominant methanogenic pathway in these basins is hydrogenotrophic, with acetoclastic being a second major pathway in the Surat Basin. Finally, mcrA and 16S rRNA gene primer biases were predominantly seen to affect the detection of Methanocellales, Methanomicrobiales and Methanosarcinales taxa in this study. Subsurface coal methanogenic community distributions and pathways presented here provide insights into important metabolites and bacterial partners for in situ coal biodegradation.
Administrative scale economies in local government: An empirical analysis of Sabah municipalities, 2000 to 2009
Publisher: SAGE Publications
Date: 09-12-2013
Abstract: Municipal corporate centres not only perform multiple administrative functions, including supervision, monitoring and budgeting of the overall operation of local government, but also absorb significant resources. From a public policy perspective, it is thus important to determine whether administrative scale economies exist. Adopting an econometric approach, this paper investigates administrative scale effects and the determinants of administrative intensity at the corporate level for 22 local authorities in the Malaysian state of Sabah from 2000 to 2009. Our results indicate that there is an inverted U-shaped scale effect for staff size on administrative intensity in the small urban s le, while own-source revenue is the most important factor in determining administrative intensity in all local authorities and big urban s les. Several policy recommendations are proposed.
A Comparative Study of Different Quality Oil Shales Developed in the Middle Jurassic Shimengou Formation, Yuqia Area, Northern Qaidam Basin, China
Publisher: MDPI AG
Date: 08-02-2022
DOI: 10.3390/EN15031231
Abstract: Oil shales are developed in the Shale Member of the Middle Jurassic Shimengou Formation in the Qaidam Basin, China. The oil shales can be classified into three quality groups (low-, medium-, and high-quality oil shales) through a comprehensive analysis protocol that includes Rock-Eval pyrolysis, total organic carbon (TOC) content, proximate analysis, gas chromatography-mass spectrometry (GC-MS), X-ray diffraction (XRD), major and trace element analyses, and maceral analysis. The low-quality oil shales mainly contain type II1 kerogen, the medium-quality oil shales mainly contain type I-II1 kerogen, and the high-quality oil shales mainly contain type I kerogen. All are immature to early thermally mature. The oil yield of the oil shales is directly related to their quality and are positively correlated with TOC content and calorific value. All studied s les were deposited under anaerobic conditions but in different paleoenvironments. The low-quality oil shales were mainly deposited in fresh-water environments, whereas the high-quality oil shales were usually developed in highly saline and reducing environments. Salinity stratification and evidence of algal blooms that are conducive to organic matter enrichment were identified in both medium- and high-quality oil shales, the latter having the highest paleoproductivity and the best preservation conditions. In summary, shale quality is controlled by a combination of factors, including algal abundance, preservation conditions, the existence of algal blooms and salinity stratification, and paleoproductivity. This study reveals how these different factors affect the quality of oil shales, which might provide an in-depth explanation for the formation process of lacustrine oil shales.

Reappraisal of hydrocarbon biomarkers in Archean rocks
Publisher: Proceedings of the National Academy of Sciences
Date: 27-04-2015
Abstract: The advent of oxygenic photosynthesis set the stage for the evolution of complex life on an oxygenated planet, but it is unknown when this transformative biochemistry emerged. The existing hydrocarbon biomarker record requires that oxygenic photosynthesis and eukaryotes emerged more than 300 million years before the Great Oxidation Event [∼2.4 billion years ago (Ga)]. We report that hopane and sterane concentrations measured in new ultraclean Archean drill cores from Australia are comparable to blank concentrations, yet their concentrations in the exteriors of conventionally collected cores of stratigraphic equivalence exceed blank concentrations by more than an order of magnitude due to surficial contamination. Consequently, previous hydrocarbon biomarker reports no longer provide valid evidence for the advent of oxygenic photosynthesis and eukaryotes by ∼2.7 Ga.

An assessment of rate-pegging in New South Wales local government
Publisher: University of Technology, Sydney (UTS)
Date: 2010
Abstract: Rate-pegging has been in place in NSW for more than thirty years with broad support from all sides of politics. However, in late 2008 the NSW Government commissioned IPART to report on the adequacy of rate-pegging. IPART produced a Draft Report and then a Final Report, which has not yet been released by the NSW Government. Nevertheless, the NSW Government has made some changes to local government finance by way of capping developer charges, allowing IPART to make annual rate-pegging determinations, and enabling IPART to consider special variations in rate-pegging. Against this background, this paper considers the principles and practice of rate-pegging in NSW, the rationale for rate-pegging and counter-arguments on its desirability, as well as its economic effects on NSW local government finance relative to other Australian local government jurisdictions.

Determining the extent of biodegradation of fuels using the diastereomers of acyclic isoprenoids
Publisher: American Chemical Society (ACS)
Date: 02-03-2007
DOI: 10.1021/ES0621288
Abstract: Improved testing and remediation procedures for sites contaminated with petroleum hydrocarbons are a priority in remote cold regions such as Antarctica, where costs are higher and remediation times are longer. Isoprenoid/n-alkane ratios are commonly used to determine the extent of biodegradation at low levels but are not useful once the n-alkanes have been removed. This study demonstrates how the diastereomers of the acyclic isoprenoids can be used to determine the extent of biodegradation in moderately biodegraded fuel in soils from a bioremediation trial at Casey Station, Antarctica. The biological diastereomers of pristane (meso RS = SR) are depleted more rapidly during moderate biodegradation than the geological or mature diastereomers (RR and SS), and thus, the ratio of pristane diastereomers can determine the level of biodegradation. The statistical difference among mean diastereomer ratios for s les grouped according to the biodegradation scale and pristane hytane ratios was highly significant. The ratios of norpristane and phytane diastereomers also change with biodegradation in a similar fashion, and different levels of sensitivity exist for each. Additional benefits are that the method can be performed on conventional gas chromatographs by non-specialist chemists and that the ratios are independent of evaporation and do not necessarily require a non-biodegraded reference (T0) s le. This study details a simple alternative method for determining the extent of biodegradation of fuels at moderate levels that can be applied to a wide range of petroleum products.

Administrative intensity and financial sustainability: An empirical analysis of the Victorian local government system
Publisher: Wiley
Date: 27-05-2022
DOI: 10.1111/POLP.12466
Abstract: A substantial empirical literature has examined the relationships between organizational characteristics and performance across the public sector, including the determinants of financial sustainability in local government. However, with the exception of one 2020 source, no attempt has been made to investigate the impact of administrative intensity on municipal financial sustainability. To address this gap in the empirical literature, this article examines the influence of administrative intensity on financial sustainability in the Victorian state local government system in Australia, as proxied by financial sustainability ratios, over the period 2014/15–2018/19. In addition, we consider whether variations in the relationship between administrative intensity and financial sustainability exist between rural and urban Victorian local authorities. We find that administrative intensity significantly affects the financial sustainability indices of local councils. In addition, there are differences across rural and urban councils in the association between financial sustainability and administrative intensity. The study concludes with a brief discussion of its broader policy implications.

Administrative intensity in local government: Do administrative scale economies exist in New South Wales local government?
Publisher: Wiley
Date: 13-05-2022
DOI: 10.1111/POLP.12467
Abstract: A vast empirical literature has investigated economies of scale in local service provision, especially in water and waste management. By contrast, the question of scale economies in local government administration has attracted much less attention, especially in Australian local government. To address this gap in the Australian empirical literature, we investigated administrative scale economies in the New South Wales (NSW) local government system for rural, regional, and urban local authorities over the period 2014/15 to 2017/18. We find that total municipal population and municipal staff exhibit a U‐shaped relationship with the total administration costs of urban councils in NSW. However, we find no economies of scale for administrative intensity in rural and regional councils in NSW.

Representative Democracy in Australian Local Government
Publisher: University of Technology, Sydney (UTS)
Date: 20-01-2009
Abstract: In an assessment of representative democracy in Australian local government, this paper considers long-run changes in forms of political representation, methods of vote counting, franchise arrangements, numbers of local government bodies and elected representatives, as well as the thorny question of constitutional recognition. This discussion is set against the background of ongoing tensions between the drive for economic efficiency and the maintenance of political legitimacy, along with more deep-seated isions emerging from the legal relationship between local and state governments and the resultant problems inherent in local government autonomy versus state intervention.

Assessing fuel spill risks in polar waters: Temporal dynamics and behaviour of hydrocarbons from Antarctic diesel, marine gas oil and residual fuel oil
Publisher: Elsevier BV
Date: 09-2016
DOI: 10.1016/J.MARPOLBUL.2016.06.042
Abstract: As part of risk assessment of fuel oil spills in Antarctic and subantarctic waters, this study describes partitioning of hydrocarbons from three fuels (Special Antarctic Blend diesel, SAB marine gas oil, MGO and intermediate grade fuel oil, IFO 180) into seawater at 0 and 5°C and subsequent depletion over 7days. Initial total hydrocarbon content (THC) of water accommodated fraction (WAF) in seawater was highest for SAB. Rates of THC loss and proportions in equivalent carbon number fractions differed between fuels and over time. THC was most persistent in IFO 180 WAFs and most rapidly depleted in MGO WAF, with depletion for SAB WAF strongly affected by temperature. Concentration and composition remained proportionate in dilution series over time. This study significantly enhances our understanding of fuel behaviour in Antarctic and subantarctic waters, enabling improved predictions for estimates of sensitivities of marine organisms to toxic contaminants from fuels in the region.

Municipal Responses to COVID-19: the case of library closures in New South Wales local government
Publisher: FapUNIFESP (SciELO)
Date: 02-2021
DOI: 10.1590/0034-761220200174
Abstract: Abstract In response to the COVID-19 pandemic, the New South Wales (NSW) government ordered the closure of all municipal libraries in order to limit the impact of the contagion. As a result, 372 public libraries in NSW ceased operation on the 23rd March 2020. While the closure of public libraries will undoubtedly contribute to restricting the spread of the coronavirus, given the pivotal role played by municipal libraries in local communities, as well as the special characteristics of library patrons, it will have other negative consequences. In this paper we consider the impact of the closure of municipal libraries in NSW from two perspectives: (a) its effect on the fiscal circumstances of local authorities and (b) its impact on the spread of the corona contagion as well as its broader effects on local community wellbeing. We conclude that rather than complete closure, partial constraints on library use should have been considered.

Diversity and metagenome analysis of a hydrocarbon-degrading bacterial consortium from asphalt lakes located in Wietze, Germany
Publisher: Springer Science and Business Media LLC

DOI: 10.1186/S13568-021-01250-4
Abstract: The pollution of terrestrial and aquatic environments by petroleum contaminants, especially diesel fuel, is a persistent environmental threat requiring cost-effective and environmentally sensitive remediation approaches. Bioremediation is one such approach, but is dependent on the availability of microorganisms with the necessary metabolic abilities and environmental adaptability. The aim of this study was to examine the microbial community in a petroleum contaminated site, and isolate organisms potentially able to degrade hydrocarbons. Through successive enrichment of soil microorganisms from s les of an historic petroleum contaminated site in Wietze, Germany, we isolated a bacterial consortium using diesel fuel hydrocarbons as sole carbon and energy source. The 16S rRNA gene analysis revealed the dominance of Alphaproteobacteria . We further reconstructed a total of 18 genomes from both the original soil s le and the isolated consortium. The analysis of both the metagenome of the consortium and the reconstructed metagenome-assembled genomes show that the most abundant bacterial genus in the consortium, Acidocella , possess many of the genes required for the degradation of diesel fuel aromatic hydrocarbons, which are often the most toxic component. This can explain why this genus proliferated in all the enrichment cultures. Therefore, this study reveals that the microbial consortium isolated in this study and its dominant genus, Acidocella , could potentially serve as an effective inoculum for the bioremediation of sites polluted with diesel fuel or other organic contaminants.

Assessing the Effect of Diesel Fuel on the Seed Viability and Germination of Medicago sativa Using the Event-Time Model
Publisher: MDPI AG
Date: 19-08-2020
Abstract: The remediation of contaminated sites using plant-based techniques has gained increasing attention in recent decades. However, information on the effects of contaminant imbibition on seed viability and germination rates are often lacking in the literature. To this end, our research investigated, by means of an event-time model, the effect of diesel fuel imbibition on the seed viability and germination rate of Medicago sativa, a plant species with great potential for remediation of organic contaminants. The event-time model provided an accurate and biologically relevant method for analysing germination data. Our results reveal that the direct imbibition of diesel fuel by M. sativa seeds for ≤48 h, or their exposure to soil diesel fuel concentrations of 0–10 g/kg diesel fuel, affects their germination rates, as shown by increasing t50 values from 90.6 (±2.78) to 114.2 (±2.67) hours, without significantly affecting seed viability. On the other hand, diesel fuel imbibition of longer duration, or the exposure of M. sativa seeds to ≥20 g/kg diesel fuel-contaminated soils, leads to no further effect on time to seed emergence. Instead, these conditions compromise seed viability, resulting in a decrease in the proportion of germinated seeds from 0.91 (±0.03) in 10 g/kg diesel fuel contaminated soil to 0.84 (±0.04) and 0.70 (±0.05) in 20 and 30 g/kg diesel fuel-contaminated soils, respectively. The fact that low concentrations of diesel fuel and 0–48 h of direct imbibition delayed seed emergence without adversely affecting the percentage of viable seeds suggests that this inhibitory effect on germination at low diesel fuel exposure could be attributed more to physical constraints rather than biological damage on the seeds. The models used in this study provide an accurate and biologically relevant method for the analyses of germination data. This is vital since expensive germination experiments, be it in the field of toxicology or agriculture, deserve to be accurately analysed.
Hydrocarbon biomarkers preserved in carbonate veins of potentially Paleoproterozoic age, and implications for the early biosphere
Publisher: Wiley
Date: 05-07-2018
DOI: 10.1111/GBI.12305
Abstract: Research on the early rise of oxygenic photosynthesis and eukaryotes has recently encountered a major pitfall, as some hopane and sterane biomarkers reported in Archaean rocks are the results of contamination. Following an extensive petrological framework in the Pilbara Craton, Western Australia, oil-bearing fluid inclusions and solid bitumens were identified in replacement and hydrothermal carbonate veins cross-cutting Archaean metasedimentary rocks. The 2.55-2.63 billion years old metasedimentary rocks were found to be depleted of indigenous biomarkers. Here we show novel biomarker results from the solvent extraction of the carbonate veins. Volcanic rock blanks, outside rinses, and instrumental blanks showed no biomarkers, and the surrounding rocks were metamorphosed to a sufficiently high extent to not yield any biomarkers, but the biomarkers found in the veins are most likely indigenous. Biomarkers detected include C

Structural reform, revenue adequacy and optimal tax assignment in local government
Publisher: University of Technology, Sydney (UTS)
Date: 14-05-2009
Abstract: A striking feature of local government reform in many Commonwealth countries has been a heavy reliance on structural reform, often in the form of forced local council amalgamation. This paper argues that the long-run success of structural change in local government hinges on several key factors, not least that voluntary rather than compulsory council mergers have a far greater chance of success. A second key ingredient resides in a high degree of local autonomy in both the composition and operation of decentralized governmental functions. A third vital factor lies in ensuring that revenue and tax assignment is sufficient to provide local government with financial autonomy. Finally, adequate powers of taxation need to be accorded to local government and this requires careful consideration of the types of taxes most suited to local government.

Predicting the weathering of fuel and oil spills: A diffusion-limited evaporation model
Publisher: Elsevier BV
Date: 2018
DOI: 10.1016/J.CHEMOSPHERE.2017.09.142
Abstract: The majority of the evaporation models currently available in the literature for the prediction of oil spill weathering do not take into account diffusion-limited mass transport and the formation of a concentration gradient in the oil phase. The altered surface concentration of the spill caused by diffusion-limited transport leads to a slower evaporation rate compared to the predictions of diffusion-agnostic evaporation models. The model presented in this study incorporates a diffusive layer in the oil phase and predicts the diffusion-limited evaporation rate. The information required is the composition of the fluid from gas chromatography or alternatively the distillation data. If the density or a single viscosity measurement is available the accuracy of the predictions is higher. Environmental conditions such as water temperature, air pressure and wind velocity are taken into account. The model was tested with synthetic mixtures, petroleum fuels and crude oils with initial viscosities ranging from 2 to 13,000 cSt. The tested temperatures varied from 0 °C to 23.4 °C and wind velocities from 0.3 to 3.8 m/s. The average absolute deviation (AAD) of the diffusion-limited model ranged between 1.62% and 24.87%. In comparison, the AAD of a diffusion-agnostic model ranged between 2.34% and 136.62% against the same tested fluids.

The Influence of Administrative Intensity on Efficiency: An Empirical Analysis of Australian Universities
Publisher: Wiley
Date: 05-06-2023
Abstract: While a voluminous empirical literature has investigated university efficiency, much less attention has focused on the impact of administrative intensity on university performance. In this article, we seek to contribute to the empirical literature by examining the relationship between operational efficiency and administrative intensity in the Australian higher education sector over the period 2009/10–2018/19 using a second stage bootstrapping Data Envelopment Analysis (DEA) fractional regression model. We find that administrative intensity positively affects the performance of universities for both the standard and bias‐corrected efficiency models. Moreover, administrative intensity exhibits an inverted U‐shaped relationship with university efficiency. We also find that administrative intensity has a differential impact on the efficiency of the different types of university. Various public policy implications are considered.

Modelling Sectoral Energy Consumption in Malaysia: Assessing the Asymmetric Effects
Publisher: MDPI AG
Date: 05-02-2022
DOI: 10.3390/SU14031816
Abstract: Economic growth, energy prices, technological innovations, and financial depth all play a vital role in sectoral energy consumption. Early studies have extensively examined the interactions among these variables, which are important in developing policies on energy consumption. However, to date, most studies have estimated energy consumption in a linear fashion. If the actual relationship is non-linear or asymmetric, then the inferences drawn from a linear framework may be misleading. Hence, in this study, we employed a non-linear autoregressive distributed lag (NARDL) approach to analyse Malaysian sectoral energy consumption from 1978 to 2016. We found that the bounds test of the NARDL indicates the presence of cointegration among the variables. The key findings include: (1) a rise in income increases energy consumption throughout all sectors, but sectoral energy consumption does not respond significantly to a fall in income (2) both increases and decreases in energy prices reduce industrial energy consumption, but residential and commercial sectors’ energy consumption react positively to price falls (3) technological advancement increases transportation energy consumption and (4) both an increase and decrease of credit availability to private sectors reduce industrial energy consumption, but transportation energy consumption reacts positively to financial deepening. Moreover, the effects at the sectoral level were asymmetrical. The findings indicate that the changes in selected macroeconomic variables were found to have a Granger causality effect on sectoral energy consumption. Given these findings, our study offers empirical support for the inclusion of non-linearity or asymmetric effects when modelling sectoral energy consumption.

Abstract: Diesels and lubricants used at research stations can persist in terrestrial and marine sediments for decades, but knowledge of their effects on the surrounding environments is limited. In a 5 year in situ investigation, marine sediment spiked with Special Antarctic Blend (SAB) diesel was placed on the seabed of O'Brien Bay near Casey Station, Antarctica and s led after 5, 56, 65, 104 and 260 weeks. The rates and possible mechanisms of removal of the diesel from the marine sediments are presented here. The hydrocarbons within the spiked sediment were removed at an overall rate of 4.7mg total petroleum hydrocarbons kg(-1) sediment week(-1), or 245mgkg(-1)year(-1), although seasonal variation was evident. The concentration of total petroleum hydrocarbons fell markedly from 2020±340mgkg(-1) to 800±190mgkg(-1), but after 5 years the spiked sediment was still contaminated relative to natural organic matter (160±170mgkg(-1)). Specific compounds in SAB diesel preferentially decreased in concentration, but not as would be expected if biodegradation was the sole mechanism responsible. Naphthalene was removed more readily than n-alkanes, suggesting that aqueous dissolution played a major role in the reduction of SAB diesel. 1,3,5,7-Teramethyladamantane and 1,3-dimethyladamantane were the most recalcitrant isomers in the spiked marine sediment. Dissolution of aromatic compounds from marine sediment increases the availability of more soluble, aromatic compounds in the water column. This could increase the area of contamination and potentially broaden the region impacted by ecotoxicological effects from shallow sediment dwelling fauna, as noted during biodegradation, to shallow (<19m) water dwelling fauna.

Abstract: The purpose of this paper is to contrast the marketing strategies of the New England Australia wine‐producing region with those of the Languedoc‐Roussillon region in France. While the two regions occupy similar market positions, they nonetheless reveal diametrically opposed marketing strategies. Against the background of this comparative discussion, the paper proposes methods to enhance the development of the New England Australia wine region so that it becomes a more complete ex le of successful rural restructuring. This paper uses a comparative, political economy approach to explore the marketing strategies of the New England Australia wine‐producing region, and the Languedoc‐Roussillon region in France. In particular, following the work of Garcea‐Parpet, the paper seeks to demonstrate that markets are most usefully viewed as social and political/legal constructs, as well as economic exchanges, and that focussing on the former elements is a fruitful way to proceed, both in terms of analysis and policy prescription for the industry. Comparison with the Languedoc‐Roussillon region in France generates future potential opportunities for New England Australia. A number of issues are discussed with respect to the organisation of the industry and its representation, particularly focusing on leadership and the extent to which leadership was both a catalyst for change and a driver of continued success in the case of Languedoc‐Roussillon. This paper represents the first exploration of the impact of regional status for the New England Australia wine region and the first comparative analysis of the region with Languedoc‐Roussillon.

From the Surface Ocean to the Seafloor: Linking Modern and Paleo-Genetics at the Sabrina Coast, East Antarctica (IN2017_V01)

DOI: 10.1029/2022JG007252
Abstract: With ongoing climate change, research into the biological changes occurring in particularly vulnerable ecosystems, such as Antarctica, is critical. The Totten Glacier region, Sabrina Coast, is currently experiencing some of the highest rates of thinning across all East Antarctica. An assessment of the microscopic organisms supporting the ecosystem of the marginal sea‐ice zone over the continental rise is important, yet there is a lack of knowledge about the ersity and distribution of these organisms throughout the water column, and their occurrence and/or preservation in the underlying sediments. Here, we provide a taxonomic overview of the modern and ancient marine bacterial and eukaryotic communities of the Totten Glacier region, using a combination of 16S and 18S rRNA licon sequencing (modern DNA) and shotgun metagenomics (sedimentary ancient DNA, sed aDNA). Our data show considerable differences between eukaryote and bacterial signals in the water column versus the sediments. Proteobacteria and diatoms dominate the bacterial and eukaryote composition in the upper water column, while diatoms, dinoflagellates, and haptophytes notably decrease in relative abundance with increasing water depth. Little diatom sed aDNA is preserved in the sediments, which are instead dominated by Proteobacteria and Retaria. We compare the diatom microfossil and sed aDNA record and link the weak preservation of diatom sed aDNA to DNA degradation while sinking through the water column to the seafloor. This study provides the first assessment of DNA transfer from ocean waters to sediments and an overview of the microscopic communities occurring in the climatically important Totten Glacier region.

REVIEW NOTE: Local Government Reform and Local Government Finance
Publisher: University of Technology, Sydney (UTS)
Date: 2009
Abstract: The multi-faceted problem of local government finance has attracted increasing attention in the new millennium. The reasons for the renewed interest in this thorny question are comparatively straightforward. In the first place, for the past two decades all public sector institutions have been profoundly affected by the twin revolutions simultaneously sweeping the world – the globalization of the international economy and the information revolution wrought by the computer age – and local government is no exception. Not only have these inexorable forces had dramatic implications for the structure of government as a whole, and relationships between the different tiers of government, but also for service provision and public finance, including local public finance. Secondly, substantially heightened demands on local government, together with limited access to adequate funding, have seen the genesis of a deepening crisis in the financial sustainability of local government entities.
The Local Capacity, Local Community and Local Governance Dimensions of Sustainability in Australian Local Government
Publisher: University of Technology, Sydney (UTS)
Date: 2011
Abstract: The problem of the ‘financial sustainability’ of in idual local councils represents the most significant policy question at issue in contemporary debate on Australian local government. This concern with financial sustainability has not only dominated almost all recent local government conferences across Australia, but it has also formed the capstone of several public inquiries into state local government systems. For instance, at the state level, both the South Australian Financial Sustainability Review Board’s (FSRB) (2005) Rising to the Challenge and the Independent Inquiry into the Financial Sustainability of NSW Local Government’ s (LGI) (2006) Are Councils Sustainable were centrally occupied with determining the meaning of financial sustainability in Australian local government and developing measures of financial sustainability. Moreover, the Queensland Local Government Association (LGAQ) (2006) Size, Shape and Sustainability (SSS) program, the Western Australian Local Government Association (WALGA) (2006) Systemic Sustainability Study and the Local Government Association of Tasmania (LGAT) (2007) Review of the Financial Sustainability of Local Government in Tasmania had at their core the problem of assessing financial sustainability in their respective local government systems.

Did amalgamation make local government more fit for the future?
Publisher: Wiley
Date: 09-12-2022
Abstract: Local government amalgamations, mostly aimed at improving financial sustainability, remain a strongly contested public policy option. Proponents of amalgamation tend to emphasise the advantages of scale and plan around population size targets. By contrast, some scholars note the importance of understanding the needs and tastes of residents for local public services and stress the dangers of amalgamation dominated by population size considerations alone. In this paper, we conduct a robust empirical investigation of a recent amalgamation program dominated by population size considerations. Our results suggest that local government boundaries constructed principally to secure scale benefits have largely failed to deliver on the pecuniary promise of its public policy proponents. We conclude by offering some central public policy recommendations aimed at ensuring that future amalgamation programs might be more successful.
Hydrocarbons preserved in a ~2.7 Ga outcrop sample from the Fortescue Group, Pilbara Craton, Western Australia
Publisher: Wiley
Date: 13-11-2015
DOI: 10.1111/GBI.12117
Abstract: The hydrocarbons preserved in an Archean rock were extracted, and their composition and distribution in consecutive slices from the outside to the inside of the rock were examined. The 2.7 Ga rock was collected from the Fortescue Group in the Pilbara region, Western Australia. The bitumen I (solvent-extracted rock) and bitumen II (solvent-extracted hydrochloric acid-treated rock) fractions have different hydrocarbon compositions. Bitumen I contains only trace amounts of aliphatic hydrocarbons and virtually no aromatic hydrocarbons. In contrast, bitumen II contains abundant aliphatic and aromatic hydrocarbons. The difference seems to reflect the weathering history and preservational environment of the investigated rock. Aliphatic hydrocarbons in bitumen I are considered to be mainly from later hydrocarbon inputs, after initial deposition and burial, and are therefore not indigenous. The lack of aromatic hydrocarbons in bitumen I suggests a severe weathering environment since uplift and exposure of the rock at the Earth's surface in the Cenozoic. On the other hand, the high abundance of aromatic hydrocarbons in bitumen II suggests that bitumen II hydrocarbons have been physically isolated from removal by their encapsulation within carbonate minerals. The richness of aromatic hydrocarbons and the relative scarcity of aliphatic hydrocarbons may reflect the original compositions of organic materials biosynthesised in ancient organisms in the Archean era, or the high thermal maturity of the rock. Cyanobacterial biomarkers were observed in the surficial slices of the rock, which may indicate that endolithic cyanobacteria inhabited the surface outcrop. The distribution of aliphatic and aromatic hydrocarbons implies a high thermal maturity, which is consistent with the lack of any specific biomarkers, such as hopanes and steranes, and the prehnite-pumpellyite facies metamorphic grade.

Black sandstones in the Midland Valley of Scotland: Thermally metamorphosed hydrocarbon reservoirs?
Publisher: Cambridge University Press (CUP)
Date: 1993
DOI: 10.1017/S0263593300005927
Abstract: Carboniferous sandstones from within the thermal aureoles of igneous intrusions in the Midland Valley of Scotland sometimes have a strong, black colour and are termed ‘black sandstones’. Tait (1926) concluded that the black sandstones are the products of the thermal metamorphism of petroliferous sandstones, a theory which is discussed here in the light of modern petrological and geochemical techniques. The black colour of the sandstones is due to an amorphous, opaque bitumen which usually coats illitic clays, fills porosity and was mostly emplaced at a fairly late diagenetic stage. This solid bitumen has a low reflectance ( c . 0·15% R 0 ), no fluorescence under blue-light excitation, is insoluble in organic solvents, is isotopically heavy and has a very low H/C atomic ratio. These data, together with the field relationships of the black sandstones and igneous intrusions, suggest that the bitumen was formed by the thermal alteration of hydrocarbons, as described by Tait (1926), rather than by other possible mechanisms such as the deasphalting of an oil, or the generation of hydrocarbons from organic-rich rocks heated by igneous intrusions, followed by fractionation during migration. This conclusion suggests that by the time of emplacement of the quartz-dolerite intrusions, and some of the alkali-dolerite sills, there had been widespread generation and migration of hydrocarbons which possibly could have been preserved to the present day where not thermally altered.

Is bigger better? An empirical analysis of waste management in New South Wales
Publisher: Elsevier BV
Date: 05-2015
DOI: 10.1016/J.WASMAN.2015.01.024
Abstract: Across the world, rising demand for municipal solid waste services has seen an ongoing increase in the costs of providing these services. Moreover, municipal waste services have typically been provided through natural or legal monopolies, where few incentives exist to reduce costs. It is thus vital to examine empirically the cost structure of these services in order to develop effective public policies which can make these services more cost efficient. Accordingly, this paper considers economies of size and economies of output density in the municipal waste collection sector in the New South Wales (NSW) local government system in an effort to identify the optimal size of utilities from the perspective of cost efficiency. Our results show that - as presently constituted - NSW municipal waste services are not efficient in terms of costs, thereby demonstrating that 'bigger is not better.' The optimal size of waste utilities is estimated to fall in the range 12,000-20,000 inhabitants. However, significant economies of output density for unsorted (residual) municipal waste collection and recycling waste collection were found, which means it is advantageous to increase the amount of waste collected, but maintaining constant the number of customers and the intervention area.

Enhancing rhizoremediation of petroleum hydrocarbons through bioaugmentation with a plant growth-promoting bacterial consortium
Publisher: Elsevier BV
Date: 02-2022
DOI: 10.1016/J.CHEMOSPHERE.2021.133143
Abstract: The slow rate of natural attenuation of organic pollutants, together with unwanted environmental impacts of traditional remediation strategies, has necessitated the exploration of plant-microbe systems for enhanced bioremediation applications. The identification of microorganisms capable of promoting rhizoremediation through both plant growth-promoting and hydrocarbon-degrading processes is crucial to the success and adoption of plant-based remediation techniques. In this study, through successive enrichments of soil s les from a historic oil-contaminated site in Wietze, Germany, we isolated a plant growth-promoting and hydrocarbon-degrading bacterial consortium dominated by Alphaproteobacteria. In microcosm experiments involving Medicago sativa L. and the isolated bacterial consortium, we examined the ability of the consortium to enhance rhizoremediation of petroleum hydrocarbons. The inoculation of M. sativa with the consortium resulted in 66% increase in plant biomass, and achieved a 91% reduction in diesel fuel hydrocarbon concentrations in the soil within 60 days. Metagenome analysis led to the identification of genes and taxa putatively involved in these processes. The majority of the coding DNA sequences associated with plant growth promotion and hydrocarbon degradation in this study were affiliated to Acidocella aminolytica and Acidobacterium capsulatum indicating their potential for biotechnological applications in the rhizoremediation of sites contaminated by petroleum-derived organic pollutants.

Abstract: Academic books emerge in a variety of ways. Some are the result of pure serendipity. For instance, in February 2011 Brian Dollery and I were completing a report that delved into the conceptual and theoretical foundations of shared services. Brian had also co-authored several case studies of shared services in Australian local government over the years, some of which I had contributed to.
