Queensland Coastal Wetland Resources: the Northern Territory Border to Flinders River

Protection of coastal wetland environments is an important prerequisite to effective and sustainable fisheries management and conservation of habitats for the use of future generations. Mangroves, saltmarshes and seagrasses directly support local and offshore fisheries through the provision of food, shelter, breeding and nursery grounds. As such, these vegetated wetland environments along with sandbars, mudflats, rocky foreshores and reefs have significant economic value as well as their intrinsic aesthetic and ecological values. This report summarises the results of the mapping undertaken in the Gulf of Carpentaria Region from the Queensland/Northern Territory border eastwards to the western bank of the Flinders River (hereafter called the Gulf Study Area). The study was undertaken in order to: 1. document and map coastal wetlands of the Gulf Study Area; 2. document levels of existing disturbance to and protection of these wetlands; 3. examine existing recreational, indigenous and commercial fisheries of the region; 4. evaluate the conservation values of the areas investigated from the viewpoint of fisheries productivity and as habitat for important and/or threatened species for future FHA/Marine Protected Area (MPA) declaration.

Modelling the distribution and relative abundance of feral camels in the Northern Territory using count data

The objectives of this study were to predict the potential distribution, relative abundance and probability of habitat use by feral camels in southern Northern Territory. Aerial survey data were used to model habitat association. The characteristics of ‘used’ (where camels were observed) v. ‘unused’ (pseudo-absence) sites were compared. Habitat association and abundance were modelled using generalised additive model (GAM) methods. The models predicted habitat suitability and the relative abundance of camels in southern Northern Territory. The habitat suitability maps derived in the present study indicate that camels have suitable habitat in most areas of southern Northern Territory. The index of abundance model identified areas of relatively high camel abundance. Identifying preferred habitats and areas of high abundance can help focus control efforts.

Ongoing poor management of medicines in the older-aged living independently in a rental retirement village

Background In a low socioeconomic status, small, rental retirement village, we have shown the older-aged managed their medicines poorly [1]. Objective As the number of participants was only 25, and the population in the rental retirement village turns over regularly; our objective was to determine whether the findings were consistent and ongoing. Methods We returned to the rental retirement villages after one and two years, and reassessed the management of medicines, using the same semi-structured interview method. Main outcome measure The main outcome measure was the perception of present and ongoing adherence. Results Although similar numbers (23-25) participated in the studies in 2011-2013, the actual participants changed with only 3 being interviewed on 3 occasions. Nevertheless, the findings over the 3 years were similar: less than 50% of the participants were adherent at the time of the study and unlikely to have problems in the next 6-12 months; only 50% had a good knowledge of their illnesses. Conclusions The management of medicines by the older-aged living in a low socioeconomic, rental retirement village is poor, and this finding is ongoing and consistent. This supports the need for extra assistance and resources for the older-aged, living in rental retirement villages, to manage their medicines.

Wood properties and processing outcomes for plantation grown African mahogany (Khaya senegalensis) trees from Clare, Queensland (18 and 20 year-old trees) and Katherine, Northern Territory (14 year-old trees).

Khaya senegalensis, African mahogany, a high-value hardwood, was introduced in the Northern Territory (NT) in the 1950s; included in various trials there and at Weipa, Q in the 1960s-1970s; planted on ex mine sites at Weipa (160 ha) until 1985; revived in farm plantings in Queensland and in trials in the NT in the 1990s; adopted for large-scale, annual planting in the Douglas-Daly region, NT from 2006 and is to have the planted area in the NT extended to at least 20,000 ha. The recent serious interest from plantation growers, including Forest Enterprises Australia Ltd (FEA), has seen the establishment of some large scale commercial plantations. FEA initiated the current study to process relatively young plantation stands from both Northern Territory and Queensland plantations to investigate the sawn wood and veneer recovery and quality from trees ranging from 14 years (NT – 36 trees) to 18-20 years (North Queensland – 31 trees). Field measures of tree size and straightness were complemented with log end splitting assessment and cross-sectional disc sample collection for laboratory wood properties measurements including colour and shrinkage. End-splitting scores assessed on sawn logs were relatively low compared to fast grown plantation eucalypts and did not impact processing negatively. Heartwood proportion in individual trees ranged from 50% up to 92 % of butt cross-sectional disc area for the visually-assessed dark coloured central heartwood and lighter coloured transition wood combined. Dark central heartwood proportion was positively related to tree size (R2 = 0.57). Chemical tests failed to assist in determining heartwood – sapwood boundary. Mean basic density of whole disc samples was 658 kg/m3 and ranged among trees from 603 to 712 kg/m3. When freshly sawn, the heartwood of African mahogany was orange-red to red. Transition wood appeared to be pinkish and the sapwood was a pale yellow colour. Once air dried the heartwood colour generally darkens to pinkish-brown or orange-brown and the effect of prolonged time and sun exposure is to darken and change the heartwood to a red-brown colour. A portable colour measurement spectrophotometer was used to objectively assess colour variation in CIE L*, a* and b* values over time with drying and exposure to sunlight. Capacity to predict standard colour values accurately after varying periods of direct sunlight exposure using results obtained on initial air-dried surfaces decreased with increasing time to sun exposure. The predictions are more accurate for L* values which represent brightness than for variation in the a* values (red spectrum). Selection of superior breeding trees for colour is likely to be based on dried samples exposed to sunlight to reliably highlight wood colour differences. A generally low ratio between tangential and radial shrinkages was found, which was reflected in a low incidence of board distortion (particularly cupping) during drying. A preliminary experiment was carried out to investigate the quality of NIR models to predict shrinkage and density. NIR spectra correlated reasonably well with radial shrinkage and air dried density. When calibration models were applied to their validation sets, radial shrinkage was predicted to an accuracy of 76% with Standard Error of Prediction of 0.21%. There was also a strong predictive power for wood density. These are encouraging results suggesting that NIR spectroscopy has good potential to be used as a non-destructive method to predict shrinkage and wood density using 12mm diameter increment core samples. Average green off saw recovery was 49.5% (range 40 to 69%) for Burdekin Agricultural College (BAC) logs and 41.9% (range 20 to 61%) for Katherine (NT) logs. These figures are about 10% higher than compared to 30-year-old Khaya study by Armstrong et al. (2007) however they are inflated as the green boards were not docked to remove wane prior to being tallied. Of the recovered sawn, dried and dressed volume from the BAC logs, based on the cambial face of boards, 27% could potentially be used for select grade, 40% for medium feature grade and 26% for high feature grades. The heart faces had a slightly higher recovery of select (30%) and medium feature (43%) grade boards with a reduction in the volume of high feature (22%) and reject (6%) grade boards. Distribution of board grades for the NT site aged 14 years followed very similar trends to those of the BAC site boards with an average (between facial and cambial face) 27% could potentially be used for select grade, 42% for medium feature grade, 26% for high feature grade and 5% reject. Relatively to some other subtropical eucalypts, there was a low incidence of borer attack. The major grade limiting defects for both medium and high feature grade boards recovered from the BAC site were knots and wane. The presence of large knots may reflect both management practices and the nature of the genetic material at the site. This stand was not managed for timber production with a very late pruning implemented at about age 12 years. The large amount of wane affected boards is indicative of logs with a large taper and the presence of significant sweep. Wane, knots and skip were the major grade limiting defects for the NT site reflecting considerable amounts of sweep with large taper as might be expected in younger trees. The green veneer recovered from billets of seven Khaya trees rotary peeled on a spindleless lathe produced a recovery of 83% of green billet volume. Dried veneer recovery ranged from 40 to 74 % per billet with an average of 64%. All of the recovered grades were suitable for use in structural ply in accordance to AS/NZ 2269: 2008. The majority of veneer sheets recovered from all billets was C grade (27%) with 20% making D grade and 13% B grade. Total dry sliced veneer recovery from the logs of the two largest logs from each location was estimated to be 41.1%. Very positive results have been recorded in this small scale study. The amount of colour development observed and the very reasonable recoveries of both sawn and veneer products, with a good representation of higher grades in the product distribution, is encouraging. The prospects for significant improvement in these results from well managed and productive stands grown for high quality timber should be high. Additionally, the study has shown the utility of non-destructive evaluation techniques for use in tree improvement programs to improve the quality of future plantations. A few trees combined several of the traits desired of individuals for a first breeding population. Fortunately, the two most promising trees (32, 19) had already been selected for breeding on external traits, and grafts of them are established in the seed orchard.

Child Abuse and Neglect: A Socio-legal Study of Mandatory Reporting in Australia - Report for the Northern Territory Government

This report presents the results of a study exploring the law and practice of mandatory reporting of child abuse and neglect in the Northern Territory. Government administrative data over a decade (2003-2012) were accessed and analysed to map trends in reporting of different types of child abuse and neglect (physical abuse, sexual abuse, emotional abuse, and neglect) by different reporter groups (e.g., police, teachers, doctors, nurses, vs family members, neighbours), and the outcomes of these reports (whether investigated, and whether substantiated or not). The study was funded by the Australian Government and administered through the Government of Victoria.

Peopling of the Northern Territory part 1: a white elephant in a white Australia? The Northern Territory, 1901-1920

As a result of negative net immigration during the 1890s depression, Australians at the time of Federation were preoccupied about the slow rate of growth of the population. The non-Aboriginal population at the end of 1904 was approximately three and three-quarter million. and the publication in March 1904 of the Report of the New South Wales Royal Commission on the Decline of the Birth Rate and the Mortality of Infants did nothing to allay these concerns. Despite the perceived need for more people. the desire for racial unity was paramount. The main goals of policy makers at the time were to preserve a 'white' and essentially British Australia and create an imperial bastion in the Southern Hemisphere.

Filching the Argentine colonists : the encouragement of Patagonians to the Northern Territory in the early twentieth century

This paper explores the background to the emigration of 220 settlers from Patagonia in South America to the Northern Territory during the course of World War I. The group, which arrived in Darwin on the Kwanto Maru in 1915, comprised an unusual mixture of nationalities. The breakdown given in the passenger list and the contemporary press was 113 Spaniards, 45 Russians, 30 Italians. 28 British, I Argentinian [of British parents], 1 Frenchman, 1 Serbian and 1 Greek. Some of the 'Spaniards' were presumably Spanish speaking Argentinians but most were indeed of Spanish descent, such as the Martinez, Perez and Villalba families. Of the British amongst the group, almost all were Welsh. They came as a result of inducements held out to the Welsh amongst the party in the years immediately prior to the war by the Commonwealth Government, which administered the Northern Territory after 1911. This account provides a fascinating case study of the recruitment of immigrants to Australia, and particularly to the Northern Territory, in the early twentieth century.

Burden of disease and injury in Aboriginal and non-Aboriginal populations in the Northern Territory

Objective:
To quantify the burden of disease and injury for the Aboriginal and non-Aboriginal populations in the Northern Territory.

Design and setting:
Analysis of Northern Territory data for 1 January 1994 to 30 December 1998 from multiple sources.

Main outcome measures:
Disability-adjusted life-years (DALYs), by age, sex, cause and Aboriginality.

Results:
Cardiovascular disease was the leading contributor (14.9%) to the total burden of disease and injury in the NT, followed by mental disorders (14.5%) and malignant neoplasms (11.2%). There was also a substantial contribution from unintentional injury (10.4%) and intentional injury (4.9%). Overall, the NT Aboriginal population had a rate of burden of disease 2.5 times higher than the non-Aboriginal population; in the 35-54-year age group their DALY rate was 4.1 times higher. The leading causes of disease burden were cardiovascular disease for both Aboriginal men (19.1%) and women (15.7%) and mental disorders for both non-Aboriginal men (16.7%) and women (22.3%).

Conclusions:
A comprehensive assessment of fatal and non-fatal conditions is important in describing differentials in health status of the NT population. Our study provides comparative data to identify health priorities and facilitate a more equitable distribution of health funding.

Studies in supervisory practice : the effectiveness of the practicum in teacher education in the Northern Territory

In this thesis we descend into the swampy lowlands to meet with student-teachers and their supervisors and observe them working together at different sites across the Top End of Australia. In the process we discover the multiple relationships that comprise the practicum text and the discomforting untidiness and unwieldiness, as well as the awkwardness of complexity, which surrounds research into supervisory practice. The thesis demonstrates the need to attend to the subjectivities of the participants and highlights the conflicting attitudes, beliefs, interests, and desires which are only partially realised or understood. It moves us beyond language to the sentient world of anger, love, disgust, hope, fear, despair, joy, anguish, and pain and we become immersed in a murky, incoherent, interior world of hints, shadows, and unfamiliar sounds, a world of lost innocence and conflict in which knowledge is truly embodied. Encompassing a view of supervision as moral praxis, particular attention was given to the care and protection of the self and a romanticist conception of the self was seen to predominate. The thesis demonstrates the part played by positioning and agency in the process of subjectification, the importance of emotional and relational bonding in the emergence of collegiality, the tactics of power employed by supervisors, the struggle for personal autonomy, the presence of anxiety induced by failure to pro vide feedback, the inculcation of guilt, and the complex interplay of age-related and gender effects. Attention is also given to the degree to which supervisors adopt reflective and constructivist approaches to their work. The stories reveal that supervision is much more than advising student-teachers on curriculum content, resource availability and lesson presentation. It is a process of interiority in which supervisors may need to provide emotional support in the face of displacement and disorientation, and assume the role of an abiding presence, someone capable of imaginative introjection, someone who ‘knows’. Particular attention is paid to the language of supervision which was marked by indirection, diffidence, imprecision, irony, and understatement. At the same time, the agonistic nature of language associated with the politics of the personal is made apparent. Whilst in the opinion of Liaison Lecturers, context-of-site did not appear to matter as far as acquiring teaching competence was concerned, the failure to attend to context-of-site affected how student-teachers engaged with difference and diversity. In spite of attempts to contest the myths of Aboriginal education and interrupt the discourse of impoverishment, colonialist attitudes and resistance to liberatory education persisted. The thesis ends with suggestions for alternatives to the traditional practicum and discusses the introduction of Field-Based Teacher Education into Northern Territory schools.

Adult learning experience : learning in mixed-mode forms of professional development in the Northern Territory of Australia

This qualitative research is an examination of the experience of learning within a mixed-mode teachers' professional development program. It examines how learning is affected by 'location' - geographic, institutional and personal, and how teaching may take location into account. Approaches to study, influences on learning and transformational learning are explored.

Space : the final frontier : festivals, community and place in Darwin Northern Territory, Australia

The ethnographies of two festive public events are used to analyse some aspects of community and place in Darwin, Northern Territory, Australia. Place entails layers of physical and imaginal geographies and involves local and extra-local factors. Discourses about place among those who lived in Darwin are interwoven with discourses about community. A framework of border spaces and intersections are used to look at tensions and accommodations in presenting sometimes conflicting versions/visions of Darwin.
