Progressive and reactionary rhetoric in the municipal reform debate in New South Wales,Australia

Albert Hirschman's rhetoric of reaction is a potentially powerful typology of the arguments made by both proponents and opponents of reform (1991. The rhetoric of reaction: Perversity, futility, jeopardy. Cambridge: Belknap Press of Harvard University Press). However, scholars have identified a number of gaps in the typology, in particular that it has struggled to explain the lines of rhetoric associated with disputed empirical evidence. This paper reviews Hirschman's typology before applying it to the contentious municipal amalgamation debates currently unfolding in New South Wales, Australia. We then examine the lines of attack open to progressives and reactionaries on the basis of empirical data. We conclude that the use of empirical data opens new lines of rhetoric for both ‘progressives’ and ‘reactionaries’ generally, but that both information costs and complexity significantly affect the timing and penetration of the arguments.     

The Old Kinchega Homestead: Doing Household Archaeology in Outback New South Wales, Australia

The Kinchega Pastoral Station in western New South Wales, Australia, was one of the earliest and largest in the area. A study of one of the station's homestead is demonstrating how the integration and negotiation of material and documentary evidence produces information on domestic behavior in rural Australia in the late nineteenth and early twentieth centuries and highlights the activities of women and children in an environment whose history has been dominated by the exploits of men.     

Broom (Cytisus scoparius) at Barrington Tops,New South Wales

Broom was introduced to the northern part of the Barrington Tops plateau in the 1840s Particularly since 1969, when cattle grazing and associated burning ceased in the area, Broom has spread over c 10,000 hectares, mostly in the State Forest and National Park In eucalypt-dominated vegetation, Broom invasion is shown to cause substantial reduction in species richness and foliage projective cover of native understorey vegetation, including number of eucalypt seedlings Reasons for Brooms success, and possible outcomes, are discussed Control measures to date have been ineffective; biological control appears to offer the best future prospects.     

A probable ankylosaurian (Dinosauria,Thyreophora) from the Early Cretaceous of New South Wales,Australia

Bell, P.R., Burns, M.E. & Smith, E.T. October 2017. A probable ankylosaurian (Dinosauria, Thyreophora) from the Early Cretaceous of New South Wales, Australia. Alcheringa 42, 120–124. ISSN 0311-5518.

We describe an isolated osteoderm from the Albian Griman Creek Formation where it is exposed near the town of Lightning Ridge in central-northern New South Wales, Australia. Several lines of evidence allow referral of this element to the Ankylosauria—a group that epitomises body armour and ubiquitous osteodermal coverage among dinosaurs. Despite the abundant record of fossil vertebrates from this interval, ankylosaurians have not been previously reported, although, they have been described from penecontemporaneous deposits in western Queensland and Victoria. This discovery, therefore, provides an important link between the northerly faunas (including the Griman Creek Formation) that flourished at the edge of the epeiric Eromanga Sea, with those from the sub-polar rift-valley system of Victoria during the mid-Cretaceous.

An Initial Analysis of River Discharge and Rainfall in Coastal New South Wales,Australia Using Wavelet Transforms

In many coastal catchments of south eastern New South Wales, Australia, changes in river morphology are a response to human impact superimposed on spatial and temporal patterns of variability in precipitation and discharge. Understanding, and preferably quantifying, spatial and temporal patterns of hydrologic variability are essential to understanding natural changes, and to separate these from artificial changes in river systems. Prediction and management of water resources are also dependent upon this understanding. We assess the variability in precipitation and discharge using the wavelet transform which projects the time series of data into a three dimensional surface of frequency, amplitude and time. The analysis reveals that changes across time often reflect changes in individual seasons and may be linked to changes in particular seasonal atmospheric circulation systems. Strong perturbations in the analysis of one catchment are consistent with documented, geomorphically‐effective, flooding sequences. The characteristics of the series in the transformed data reveal interesting differences at certain times and scales which may be a reflection of changes in larger scale atmospheric processes.     

Changes in stream channel morphology at tributary junctions,Lower Hunter Valley,New South Wales

Many empirically derived models of downstream changes in channel form are based on the concept of hydraulic geometry, whereby changes in channel morphological variables are related by a continuous power function to increasing discharge or its surrogate. However, changes in discharge throughout a drainage basin are normally concentrated at the junctions of stream channels. At junctions, the relationship between discharge and channel morphology is discontinuous. Some Lower Hunter Valley stream channels were surveyed upstream and downstream of tributary junctions. While significant regional downstream relationships were established, consistent trends at tributary junctions were not apparent from the data. It is possible that considerable scatter evident in ratios of change on either side of each junction was due to local within-site variability. In addition, the relative timing of discharge inputs and the nature of introduced sediment loads could be important in determining the magnitude and direction of channel change at tributary junctions. Interrelated changes in cross-sectional, profile and planform variables may be expected below junctions. The resultant channel morphology, in terms of these variables, might not be wholly determinate.     

Conodonts and tabulate corals from the Upper Ordovician Angullong Formation of central New South Wales,Australia

Zhen, Y.Y., Wang, G.X. &; Percival, I.G., August 2016. Conodonts and tabulate corals from the Upper Ordovician Angullong Formation of central New South Wales, Australia. Alcheringa 41, xxx–xxx. ISSN 0311-5518.

The Angullong Formation is the youngest Ordovician unit exposed in the Cliefden Caves area of central New South Wales. Its maximum age is constrained by a Styracograptus uncinatus graptolite Biozone fauna at the very top of the underlying Malongulli Formation, but the few fossils previously reported from higher in the Angullong Formation are either long-ranging or poorly known. From allochthonous limestone clasts in the middle part of the formation, we document a conodont fauna comprising Aphelognathus grandis, A. solidum, Aphelognathus sp., Aphelognathus? sp., Belodina confluens, Drepanoistodus suberectus, Panderodus gracilis, Panderodus sp., Phragmodus undatus, Pseudobelodina inclinata and Pseudobelodina? sp. aff. P. obtusa, which supports correlation with the Aphelognathus grandis Biozone (late Katian) of the North American Midcontinent succession. The species concepts of Aphelognathus and Pseudobelodina are reviewed in detail. Associated corals are exclusively tabulates, dominated by agetolitids, including Agetolites angullongensis sp. nov., Heliolites orientalis, Hemiagetolites breviseptatus, Hemiagetolites sp. cf. H. spinimarginatus, Navoites sp. cf. N. circumflexa, Plasmoporella bacilliforma, P. marginata, Quepora sp. cf. Q. calamus and Sarcinula sp. Affinities of the coral fauna from the Angullong Formation are closer to faunas from northern NSW and northern Queensland than to the locally recognized Fauna III of late Eastonian age in central NSW. We propose a subdivision of Fauna III to account for this difference, with the late Katian Fauna IIIB characterized by the incoming of agetolitid corals. The currently known distribution of representatives of this group with adequate age constraints suggests that agetolitids possibly originated in North China, subsequently migrating to Tarim, South China and adjacent peri-Gondwanan terranes while also spreading eastward to northern Gondwana, where they progressively moved through eastern Australia to reach the central NSW region by the early Bolindian.

Character and Age of Lateritic Weathering at Jervis Bay,Southern New South Wales

Lateritic profiles near Jervis Bay developed under humid temperate climates on a surface of considerable relief. δ¹⁸O and TL dating of these profiles indicates that their ages range from Late Mesozoic-Early Tertiary to Late Pleistocene. These profiles thus demonstrate a complexity of development far greater than that allowed for in traditional explanations which attributed lateritic weathering to the effects of tropical climates on Middle Tertiary erosional surfaces.     

Roadside Memorials: Interpreting New Deathscapes in Newcastle,New South Wales

Over recent years, roadside memorials to commemorate people killed in motor vehicle accidents have become increasingly noticeable in parts of the Australian landscape. In Newcastle, New South Wales, roadside memorials are placed for young people. The age/gender group most at risk of road death, and those most memorialised, are young men. This is linked to spatially specific constructions of masculinity which circulate within youth milieux of Newcastle. Like other memorials and monuments these ‘deathscapes’ have multiple meanings, differing between those who build, maintain and interpret them. They function as conservative memorials of youth machismo; of heroic aggression, disregard for safety and egocentrism. Roadside memorials need to be re-read as symbolic of societal flaws; of a wasteful road toll, and a testament to dominant and problematic strains of masculinity.     

Pleistocene foraminifera from Botany Bay,New South Wales

Unconsolidated sediments from a borehole in Botany Bay have been analyzed for their foraminiferal content. Faunas from between 41 and 54 m below sea level are interpreted as Pleistocene in age. The foraminiferal assemblage from 54 m indicates marine conditions of moderately deep water (25–30 m), and a climate warmer than at present. The higher assemblages indicate a more brackish environment

The foraminifera, belonging to 123 species in 67 genera, are tabulated and 24 are discussed and illustrated. Three species, Oolina bifidocostata, Fissurina alatoquadrata and Elphidium botaniensis and one subpecies, Quinqueloculina affinis atrata, are described as new.     

Studies in Urban Ecology: the First Wave of Biological Invasion by Pistacia chinensis in Armidale,New South Wales,Australia

Biological invasions by deliberately introduced organisms seriously compromise the integrity of ecosystems, but their early stages have seldom been documented, especially in urban contexts. Since the 1940s, the small Asian tree Pistacia chinensis has been widely planted in streets and gardens in Armidale, New South Wales, Australia, where it makes a major contribution to the autumn colours that are exploited to promote the city. Numerous wild plants are now becoming established in and near Armidale. This ongoing biological invasion may have been accelerated by the large size of the initial (planted) population, and by the presence of efficient avian seed dispersers. It is now at the stage of the first wild generation reaching reproductive maturity. While it is probably still possible to halt the invasion, various human factors appear to make this an unlikely prospect.     

Late Quaternary ostracods from Lake George,New South Wales

Fossil ostracods from the uppermost 3m of core LG4 from Lake George all have modern living representatives. This part of the core is thought to represent deposition during the last 60,000 years (see Singh et al., 1981b) and the lake hisotry is traced from a knowledge of the ostracod ecology.

The following distinct phases, and their respective timing, are postulated for Lake George (the timing of events should be considered with caution as few ¹⁴C dates are available): water fresh and lake full for the periods of 10,200 – 12,000 yBP and 19,100 – 20,700 yBP, water fresh, ephemeral at times, for the periods of 3,200–4,000 yBP, 7,000 yBP, 7,500 yBP, 8,500–10,200 yBP, 12,000–13,500 yBP, 20,700–23,500 yBP, 23,800–27,600 yBP and at some stage between 27,000 and 60,000 yBP; ephemeral saline water for a few short episodes between 3,200 and 4,000 yBP and for the periods of 15,600–17,400 yBP and 23,800–27,600 yBP; lake definitely dry between 17,400 and 19,100 yBP.

Data obtained from the ostracods correlate reasonably well with those of lake level fluctuations based on the study of ancient shorelines by Coventry (1976) and others based on facies analyses and the record of plant microfossils by Singh et al. (1981b).
