  • Description: Variation in the song of the male Common Blackbird was investigated within and between two locations in western Victoria. Each of 400 phrases (100 phrases per male) was characterised by 61 measurements relating to 13 aspects of each phrase. Principal component and stepwise discriminant analyses were undertaken on these measurements. Classification of blackbird song for location and individuality was based on timing within the phrase of the loudest elements. Evidence was found for within-phrase variability, with the greatest variation in the middle of the phrase. Within- and between-site comparison found that blackbird song exhibited both individual and site-specific characteristics consistent with earlier suggestions of phrase sharing within local populations. The study demonstrated that an objective statistical approach to song analysis was able to disciminate between individual birds from different locations.

  • Description: The paper examines some axiomatic definitions of separation functions that can be employed fruitfully in the analysis of side-constrained extremum problems. A study of their general properties points out connections with abstract convex analysis and recent generalizations of Lagrangian approaches to duality and exact penalty methods. Many concrete examples are brought out.

  • Description: The processes of social negotiation which sanction the elevated occupational authority of professions remain understudied. However, the conventionally ascribed complexity of professional services suggests the importance of more discursive mediums rather than objective evaluations of occupational competence. Thus, what might previously have been dismissed as mere professional ephemera may actually function as key signifiers in the development of image and status. It is within this context that Bruce Marshall’s 1958 book The Bank Audit is reviewed. Authored by an accountant, this book is significant as a rare example of an “accounting novel” and for its often distinctive portrayal of accountants and their work. A call is made for accounting historians to enliven development of the social history of accounting by searching for and studying the expansive and eclectic range of texts and other sources which elucidate the often intriguing interface between this occupation and the broader society in which it is constituted.

Organic matter dynamics in willow and eucalypt lined central Victorian streams

  • Description: The spread of exotic willows (Salix spp.) in SE Australia, New Zealand and South Africa has provoked widespread debate in scientific, management and broader communities. In Australia, the extent of spread is unknown, but at least 30000 km of river frontage in Victoria are lined by willows. Management and research literature has identified the poor knowledge of willow impacts on Southern Hemisphere aquatic ecosystems. It has been speculated that the major distinction between deciduous willows and evergreen native vegetation will be the timing and quality of litterfall. This would have flow-on consequences for metabolic processes, stream biota and water quality at reach, stream and catchment scales. These two vegetation types were studied through the preparation of partial organic matter budgets for native and willow lined reaches in a central Victorian catchment. Organic matter inputs from litter, groundwater and gross primary production (GPP), organic matter standing crop . and respiratory output were quantified. Total inputs to willow and native reaches were similar (735 and 764 g ash free dry weight m•' yl, respectively). Inputs were dominated by litterfall (-60%) and there were no significant differences in annual litterfall between sites. GPP contributed -20% of total inputs and estimates suggested there were few significant differences in annual GPP, 24 h community respiration, ratio of GPP to community respiration (PIR) or net daily metabolism (NDM) between sites. Groundwater contributed -20% of total inputs with one third of the dissolved organic matter sourced during short flow paths through riparian sediments. Aggradation at willow sites appeared to increase the riparian flow path. Willow and native sites were heterotrophic and similarly dependent on allochthonous organic matter (P/R=O.2, NDM= -.6, and ratio of net primary production to total inputs -0.1). Willow research and management should also focus on retention capacity, including the recruitment and role of LWD and the structure and function of root systems. Removal of willows potentially facilitates native vegetation establishment but simultaneously decreases retention capacity and metabolic control by the canopy. Establishing native vegetation to fulfil broader biodiversity objectives whilst retaining willows for their potentially positive roles is a management challenge. In principle, establishing native species on the upland-sides of fringing willows and under willow canopies will direct succession toward a preferred outcome without destructive disturbance. Understanding of when benefits of willows outweigh their costs is a notable gap.

  • Description: Based on a sample of 89 aggressive clinic-referred children, aged between 9 and 11 years, a longitudinal study of 1-year duration was conducted to examine (a) whether the children's perception of control and support of their mothers' to them predicted their hostile attribution of intent and hostile response selection, and (b) whether these hostile biased social cognitions mediated the relationships between their perceived maternal behaviours and their aggression. Participants completed a questionnaire covering both the perceived maternal control and support. One year later, their hostile attribution of intent and response selection, and aggression, were measured. Results showed that perceived maternal control and perceived maternal support were associated positively and negatively, respectively, with both the social cognition measures. Also, the social cognition measures mediated the relationships of the perceived maternal measures with aggression. The findings are discussed in terms of how children's hostile biased relational schemas and scripts, developed from negative parenting and insecure attachment, favour more hostile social cognitions, and how these in turn mediate children's current hostile biased social behaviours.

  • Description: Issue addressed: The Framework for Student Support Services (FSSS) in Victoria aims to foster resiliency among young people through an emphasis on prevention and early intervention. This study examined the implementation of the first 18 months of the Framework in a rural region. Methods: A process evaluation was conducted involving eight focus groups with student welfare staff and a survey of 79 schools. Results: Participants reported frustration with delays in professional development, a perceived lack of resources and difficulty engaging the community welfare and health sectors. The survey revealed that schools were targeting primary prevention activities. Conclusion: The student welfare system is successfully introducing some early intervention services. However, the system is still largely constrained to work clinically with individual high risk students. Staff are attempting to introduce a whole-school approach to promoting resiliency. There is significant variation between schools in their efforts and successes. So what?: The Framework is an ambitious, long term program. It presents major challenges for reorienting the priorities and activities of the student support system. Implementation could be improved through a statewide evaluation and learning from research on the delivery of other whole-school approaches to student support. (author abstract)

  • Description: This paper describes a model for future training in clinical and counselling psychology. The model is based on the results of psychotherapy outcome research, and the development of empirically supported therapies, as well as recent developments in the use of information technology in psychotherapeutic interventions. It is also argued that developments such as the increasing cost of mental health interventions, the wide disparities in access to specialised mental health assistance, and the rise of the mental health consumer movement all provide a context for recommendations as to optimum developments in training for clinical and counselling psychologists.

  • Description: The purpose of this study was to determine if straight sprint training transferred to agility performance tests that involved various change-of-direction complexities and if agility training transferred to straight sprinting speed. Thirty-six males were tested on a 30-m straight sprint and 6 agility tests with 2-5 changes of direction at various angles. The subjects participated in 2 training sessions per week for 6 weeks using 20-40-m straight sprints (speed) or 20-40-m change-of-direction sprints (3-5 changes of 100°) (agility). After the training period, the subjects were retested, and the speed training resulted in significant improvements (p < 0.05) in straight sprinting speed but limited gains in the agility tests. Generally, the more complex the agility task, the less the transfer from the speed training to the agility task. Conversely, the agility training resulted in significant improvements in the change-of-direction tests (p < 0.05) but no significant improvement (p > 0.05) in straight sprint performance. We concluded that straight speed and agility training methods are specific and produce limited transfer to the other. These findings have implications for the design of speed and agility training and testing protocols.

  • Description: This paper describes the MODDE (Model of Decision support system Design and Evaluation) framework in some detail. The work is in progress and is being currently applied to the EMBRACE project being developed for the Refugee Review Tribunal (RRT) of Australia. Refugee law is the general legal area we are working in, while the specific domain under investigation is that of the decision makers at the RRT. EMBRACE is a decision support system being designed to assist the RRT in maintaining consistency of decisions, and preserve discretion of decision makers as well as making it easier to cope with high volumes of work in decreasing time frames. The use of the MODDE framework is intended to facilitate systematic attention to important features of decision making in our specific legal domain and to provide a sound basis upon which to evaluate a part of the system intrinsic to user acceptance.

  • Description: Mafic to intermediate dykes are spatially and temporally closely associated with major post-tectonic granitic complexes in the western Lachlan Orogen of SE Australia. These dykes, which range petrographically from basaltic to andesitic, are concentrated within several, north- to northwest-trending zones and were emplaced during two broad intervals of extensive magmatic activity during the Silurian–Devonian period. Geochemical and Sm–Nd isotopic characteristics of these mafic intrusives are consistent with their formation in a complex subduction-related tectonic setting. Interaction between mantle-wedge material, sinking oceanic crust and input from the overlying continental crust resulted in the petrological and geochemical variations displayed by these and more felsic dykes throughout the study region. Field evidence and 40Ar/39Ar data show that in the eastern part of the Stawell Zone and in the northwest portion of the Bendigo Zone, mafic dyke were intruded between 410 and 400 Ma (Late Silurian/Early Devonian). Further emplacement in the Bendigo Zone and the eastern part of the Melbourne Zone took place at between 375 and 365 Ma (Middle to Late Devonian). Episodic mantle-derived magmatism was possibly related to step-wise rollback, slab detachment or changes in the angle and rate of westward subduction in response to periodically occurring accretionary pulses. A close spatial and temporal relationship also exists between the dykes and orogenic gold mineralisation in the central Victorian gold province. Mafic to intermediate dykes both crosscut, and are host to, mineralisation in a number of goldfields. Although there is little evidence for a direct genetic association, the two processes are linked by the common utilisation of translithospheric structures, which facilitated the rapid ascent into shallow crustal levels of both mantle-derived magma and crustal-scale ore-forming fluid systems. Previous studies have suggested that transfer of heat into the crust via ascending mafic mantle magmas can provide a thermal engine which triggers and sustains extensive crustal melting, thus explaining the commonly observed close association of mafic to intermediate and felsic intrusive suites. This study supports the viability of this mechanism and in addition, indicates that a causal link exists between the formation of mantle magmas in collisional zones and the generation of orogenic gold deposits.
