First record of contourites from Lower Devonian Liptrap Formation in southeast Australia

Typical contourite deposits associated with submarine turbidite fan deposits are recognized for the first time from the Lower Devonian Liptrap Formation at Cape Liatrap, Victoria in southeast Australia. The contourites are well integrated within the turbidite fan deposits and are characterized by thin (5–8 cm), lenticular, well-sorted coarse-grained siltstones to fine-grained sandstones with current-ripples and cross beddings. The palaeocurrent directions of the turbidite fan and contourites are perpendicular to each other, with the former directed generally westward while the latter varying from 165° to 190° southward. In view of the facies types and architecture, we suggest that the turbidite fan was developed at the base of a westward inclined palaeo-slope, at the front of which the contourites were deposited as a result of southward flowing deep-sea contour (geostrophic) currents. The depositional setting interpreted for the Liptrap Formation thus may provide a provisional model for the Lower Devonian continental slope and abyssal basin environment in the southeastern part of the Melbourne Trough.

First record of komodo dragon nesting activity and hatchling emergence from North Flores, Eastern Indonesia

For wild varanid populations, basic measures of reproductive ecology, such as distribution and selection of nest sites, are difficult to obtain. To date, nest distributions and nesting behavior for Komodo dragons (Varanus komodoensis) have only been reported from Komodo National Park. Here we report the first record of V. komodoensis nesting activity and hatchling emergence on Ontoloe Island, off the north coast of Flores. This is a significant finding for it suggests that this relatively small but well protected island supports a viable population of V. komodoensis

Reworked Devonian (Givetian-Frasnian) spores from a Permian glacially-derived sequence at Bacchus Marsh, Victoria

Emphanisporites rotatus McGregor emend. McGregor 1973 is a distinctive Devonian spore with a known primary source age range in Australia spanning the upper Givetian to early Frasnian (Middle to Late Devonian). This is the first record of the species from Victoria. It occurs as a reworked element in an Early Permian assemblage belonging to the Granularisporites confluens Zone derived from glacigene diamictite in the Bacchus Marsh area. As the predominant direction of Permian ice movement recorded in the Bacchus Marsh district was south-west to north-east, it is possible that the reworked spores were transported from Antarctica.

Addressing the potential adverse effects of school-based BMI assessments on children

Introduction. Do child obesity prevention research and intervention measures have the potential to generate adverse concerns about body image by focussing on food, physical activity and body weight? Research findings now demonstrate the emergence of body image concerns in children as young as 5 years. In the context of a large school-community-based child health promotion and obesity prevention study, we aimed to address the potential negative effects of height and weight measures on child wellbeing by developing and implementing an evidence-informed protocol to protect and prevent body image concerns. fun 'n healthy in Moreland! is a cluster randomised controlled trial of a child health promotion and obesity prevention intervention in 23 primary schools in an inner urban area of Melbourne, Australia. Body image considerations were incorporated into the study philosophies, aims, methods, staff training, language, data collection and reporting procedures of this study. This was informed by the published literature, professional body image expertise, pilot testing and implementation in the conduct of baseline data collection and the intervention. This study is the first record of a body image protection protocol being an integral part of the research processes of a child obesity prevention study. Whilst we are yet to measure its impact and outcome, we have developed and tested a protocol based on the evidence and with support from stakeholders in order to minimise the adverse impact of study processes on child body image concerns.

Lichen flora of the Mount Donna Buang Scenic Reserve, Victoria

This report investigated the lichen flora of the Mt Donna Buang Scenic Reserve in Victoria, There were several aims: to describe the lichens of the region, to produce a pictorial key enabling field identification and to determine any distribution patterns. A floristic survey covering approximately 50 square km was undertaken to determine lichen diversity of the region generally. Lichens were sampled along roads, tracks, walking trails and in sections of bush, taking into account forest type and, particularly, areas that were lichen rich. Seventy-five lichen species in 43 genera and 27 families were identified and described from the region. An unknown, species H, also was described. Of the 76 lichen species, 22 were crastose and the remainder macrolichens. The best represented families were: Cladoniaceae (8 species), Hypogymniaceae (6), Lobariaceae (7), Lecideaceae (6), Pannariaceae (6) and Parmeliaccae (6). This study described 12 species (17%) which previously were not known for Victoria and which are a first record for the state. These include: Cladonia sarmentosa (J.D. Hook & Taylor) Dodge, Graphis librata Knight, Parmelinopsis neodamaziana (Elix & Johnston) Elix & Hale, Pertusaria novaezelandiae Szatala, Placopsis pardlina f. microphylla Lamb, Porina leptalea AX. Sm., Pseudocyphellaria ardesiaca Galloway, Trapeliopsis congregant (Zahlbr.) Brako, Menegazzia myriotrema (Mull. Arg.) P. James, Bunodophoron scrobiculatum (Church. Bab,) Wedin, Parmelia testacea Stirton and Menegazzia purpurascens S. Louwhoff sp. nov.. The last eight species are new to the mainland and, apart from Menegazzia purpurascens, previously were known only from Tasmania. Five main elements of distribution were identified for the lichen flora of the Mt Donna Buang Scenic Reserve: cosmopolitan, austral/australasian, paleotropical, pantropical and western pacific. The majority of species (68%) had austral/australasian distributions, eleven (16%) were endemic to Australia and nine (13%) occurred only in Tasmania , Victoria and New Zealand. A pictorial, dichotomous key was constructed for the lichen flora of the Mt Donna Buang Scenic Reserve. Previously, keys to the lichen flora of Tasmanian rainforests were suggested as appropriate to similar areas in Victoria, however, the Victorian forests include a significant sclerophyll element The key presented is specific for the study site but is appropriate to similar regions in Victoria and has been tested in a number of these areas. The key was designed to be ‘user-friendly’ so that the experienced and inexperienced alike are able to use it. A more detailed investigation of the lichen flora of the Mt Donna Buang Scenic Reserve was carried out in order to determine distribution. A total of 50 quadrats, each 20m x 20m in size, were sampled. Within each, the dominant vegetation type was determined and individuals were identified and location noted. The cover abundance of each lichen species on each individual tree was estimated using a modified Braun-Blanquet scale. A total of 710 trees, representing 13 different species, were examined. Nothofagus cunninghamii (Hook.) Oerst, Eucalyptus regnans R Mull., Acacia dealbata Link, A. melanoxylon R. Br., Hedycarya angustifolia A. Cunn. and Atherosperma moschatum Labill. were the six most common tree species encountered at the study site. Nothofagus cunninghamii supported the greatest lichen diversity (39 species), although most species occurred on less than 10% of the trees. The majority of lichens occurring on N. cunninghamii A. melanoxylon, A. dealbata and H. angustifolia were foliose or crustose, those on Ł. regnans fruticose and foliose and those on A moschatum crustose. Bunodophoron australe was the only lichen species at the study site to occur on one host, Nothofagus cunninghamiL Many occurred on a number of different hosts, but were most common on one particular tree species. The distribution of lichens at the study site was analysed with a rnultivariate statistical package (PATN) which dealt with ‘pattern analysis’. The program ‘SSH’ in PATN which uses the Bray-Curtis ordination technique, was used to create scatterplots displaying the degree of dissimilarity between quadrats in terms of presence/absence of lichen species. The program ‘TWAY’ in PATN was used to construct a two way table to display which lichen species occurred in each vegetation type. The pattern analysis revealed that the lichens of the Mt Donna Buang Scenic Reserve were not restricted to any particular forest type, but particular lichens, or groups of lichens, tended to predominate in certain vegetation communities. This concurs with work done by others in Tasmanian forests. Quadrats which were situated in cool temperate rainforest were grouped more closely with each other than with quadrats in other vegetation types. These also supported the greatest number of lichen species. This was not surprising since N. cunninghamii the dominant tree species in cool temperate rainforest, supported the greatest lichen diversity.

Races of Albugo candida causing white blister rust on brassica vegetables in Australia

Albugo Candida races of Australian isolates from B. oleracea var. italica (broccoli), B. rapa var. pekinensis (pak choi) and var. chinensis (Chinese cabbage), and Capsella bursa-pastoris (shepherd's purse) were identified on a set of Brassicaceae hosts. Isolates from broccoli were identified as A. candida race 9 (Ac 9), from pak choi and Chinese cabbage as the sub-race V of Ac 7 or as a mixed population of sub-races A and V of the same race. Isolates from Shepherd's purse were identified as Ac 4. Australian Ac 9 isolates caused white blister disease on broccoli, broccolini, cauliflower, Brussels sprout and other related Brassicaceae hosts including B. nigra (black mustard), B. napus (oilseed rape), and on B. rapa (turnip rape) 'Torch' (a differential host of Ac 7). All cultivars of cabbage (B. oleracea var. capitata) and one new broccoli 'Booster' inoculated with isolates from broccoli were immune to the isolate tested. This result indicates that the Australian A. candida varies from the European one that causes disease on cabbage as well as on other B. oleracea varieties and additionally on shepherd's purse and an American one that causes disease on cabbage. The genotype of B. nigra tested was susceptible to both Ac 9 and Ac 7. This result indicates that B. nigra can serve as a host for both races. This study provides the first record of white blister disease on B. napus ('Hobson' and 'Regent') in Australia.

The first professors of accounting in Australia

A range of contributions in the accounting history literature deal with "the first". While such studies set out to identify key points in time in the development of accounting, they may also narrow perspectives on accounting's past. This study on the first professors of accounting in Australia seeks to clarify the historical record while, at the same time, pointing out the difficulties of the task. A call is also made to set such studies within the ambit of a theme identified by Carnegie and Napier (1996, 2000) as "comparative international accounting history".

First fossil finds of some Australian Bryozoa (Cheilostomata)

The abundant fossil record of well-preserved Bryozoa in samples from the Tertiary of Victoria and South Australia includes some 'first fossil finds' which are recorded here. Several are of species known from the Recent of the Australian or Indo-West-Pacific regions, but some represent genera with a much wider temporal and geographical range. Of the 11 species illustrated, six are known, or may be inferred, to have inhabited 'sand fauna' environments. Specimens of one species are complete enough to allow its formal description as Chlidoniopsis inopina sp. nov.

Oxygen delivery to patients after cardiac surgery : a medical record audit

OBJECTIVE: To describe how intensive care nurses manage the administration of supplemental oxygen to patients during the first 24 hours after cardiac surgery.
METHODS: A retrospective audit was conducted of the medical records of 245 adult patients who underwent cardiac surgery between 1 January 2005 and 31 May 2008 in an Australian metropolitan hospital. Physiological data (oxygen saturation measured by pulse oximetry and respiratory rate) and intensive care unit management data (oxygen delivery device, oxygen flow rate and duration of mechanical ventilation) were collected at hourly intervals over the first 24 hours of ICU care.
RESULTS: Of the 245 patients whose records were audited, 185 were male; mean age was 70 years (SD, 10), and mean APACHE II score was 17.5 (SD, 5.14). Almost half the patients (122, 49.8%) were extubated within 8 hours of ICU admission. The most common oxygen delivery device used immediately after extubation was the simple face mask (214 patients, 87%). Following extubation, patients received supplemental oxygen via, on average, two different delivery devices (range, 1-3), and had the delivery device changed an average of 1.38 times (range, 0-6) during the 24 hours studied. Twenty-two patients (9%) received non-invasive ventilation or high-flow oxygen therapy, and 16 (7%) experienced one or more episode of hypoxaemia during mechanical ventilation. A total of 148 patients (60%) experienced one or more episodes of low oxygenation or abnormal respiratory rate during the first 24 hours of ICU care despite receiving supplemental oxygen.
CONCLUSION: These findings suggest that the ICU environment does not protect cardiac surgical patients from suboptimal oxygen delivery, and highlights the need for strategies to prompt the early initiation of interventions aimed at optimising blood oxygen levels in cardiac surgical patients in the ICU.

Raising 'standards' in schools : considerations in the first stage of an improvement intervention

This article discusses the initial phase of a government-funded intervention to raise school achievement in a cluster of schools with below average standardised test results. Five schools - four primary schools and one secondary school - in the far outer reaches of Melbourne achieved lower standardised test scores in literacy and numeracy than the state average. Two departmental strategies were in place before my involvement the appointment of a coaching teacher in each school, and funding for a four day intensive residential professional learning workshop for these coaching teachers, to be held at the beginning of the 2009 school year. lt was at this stage that I became involved in what was planned to be an ongoing research program to record, monitor and evaluate the success of the intervention.

First records of dive durations for a hibernating sea turtle

The first published record, from the early 1970s, of hibernation in sea turtles is based on the reports of the indigenous Indians and fishermen from Mexico, who hunted dormant green turtles (Chelonia mydas) in the Gulf of California. However, there were no successful attempts to investigate the biology of this particular behaviour further. Hence, data such as the exact duration and energetic requirements of dormant winter submergences are lacking. We used new satellite relay data loggers to obtain the first records of up to 7 h long dives of a loggerhead turtle (Caretta caretta) overwintering in Greek waters. These represent the longest dives ever reported for a diving marine vertebrate. There is strong evidence that the dives were aerobic, because the turtle surfaced only for short intervals and before the calculated oxygen stores were depleted. This evidence suggests that the common belief that sea turtles hibernate underwater, as some freshwater turtles do, is incorrect.
