Terrestrial apnoeas and the development of cardiac control in Australian fur seal (Arctocephalus pusillus doriferus) pups

The development of cardiac control in association with terrestrial respiration patterns was examined throughout the period of maternal dependence in Australian fur seal pups. Resting eupnoic heart rate and respiration rate were significantly correlated (r² = 0.49) and both decreased with age (P < 0.05 in both cases). From an early age (1 month), pups displayed terrestrial apnoeas (18.1 ± 0.5 s) accompanied by substantial bradycardia (127 beats min^-1, a 13% decrease from eupnoic HR). Terrestrial apnoea duration increased significantly with age reaching a mean of 41 s just prior to weaning, slightly lower than the mean dive duration (52 s) previously recorded for pups of the same age. Correspondingly, mean apnoic heart rate decreased with age to 74 beats min^-1 just prior to weaning, representing a 25% decrease on eupnoic heart rate. Importantly, concomitant with the decrease in mean apnoic heart rate with age, an increase in the control
of bradycardia was evident with the variability in instantaneous apnoic heart decreasing such that older pups were able to maintain a low steady heart rate for the duration of the apnoea. The changes seen in these parameters are similar to those reported during postnatal development in elephant seals (Mirounga spp.) and harbour seals (Phoca vitulina), and are considered indicative of the development of cardiac control. These findings suggest a common strategy for the development of bradycardia control in both otariid and phocid seals.

Managing the career development of Australian coaches

The sustainability of the sport industry is dependent upon skilled coaches. This thesis has demonstrated that unlike the corporate setting, career development in the profession of coaching is missing from both policy and practice. This omission was found to have profound detrimental impacts on sport industry sustainability and coaches' lives.

Changing perspectives : teaching and learning centres’ strategic contributions to academic development in Australian higher education

This article reports on a study of Australian teaching and learning centres to identify factors that contribute to their effective strategic leadership. These centres remain in a state of flux, with seemingly endless reconfiguration. The drivers for such change appear to lie in decision makers’ search for their centres to add more strategic value to organisational teaching, learning and the student experience. Through a synthesis of findings based on interviews, a survey of directors of centres and focus groups, the article identifies paradigmatic shifts in the ways centres see themselves, relate to their organisations and respond to external environmental forces. From an understanding of paradigm shifts, strategic contributions to academic development in the sector are framed organisationally through key points of leverage. Points of leverage are manageable actions that can be taken to maximise overall institutional impact and effectiveness.

The Civic School : Australian-Indonesian professional collaboration to model and audit the development of democratic primary classrooms and teacher language using the index for inclusion

The study is a pilot project in Australian-Indonesian institutional collaboration for the professional development of primary school teachers in West Sumatra in citizenship education. Senior staff in the department of Pancasila and Citizenship Education at the State University of Padang (UNP), West Sumatra initiated the project. UNP staff sought the collaboration of the Faculty of Education at the University of Tasmania for bringing about and sustaining changes in teacher practice needed to implement the new civic goals in the 1999 Suplemen. The Index for Inclusion was used to model and audit the development of democratic primary classrooms and language use in a cluster of Padang schools in West Sumatra. The paper describes the background to the project and how the Index for Inclusion was understood during the initial two-week implementation phase by teachers and school principals. The significance of the study lies in the potential of the Index for Inclusion internationally to citizenship education, a field of education that was not considered in the initial development of the Index project and the contribution of the multiple fields of inquiry to the evolving theoretical understandings of inclusive education.

The role of self-direction in Australian sonographers' professional development

Most sonographers are in favour of professional development; however, in the presence of deterrents and de-motivators, the utilisation of self-direction in their learning may be adversely affected. The mandatory input only nature of CPD and the large number of activities presented to sonographers may also prevent full utilisation of self-direction.

Benchmarking journalism courses with a focus on graduate employability : case Studies from three Australian universities

Benchmarking is commonly perceived as a key part of quality assurance and enhancement, and universities have had limited success to date in benchmarking, nationally or internationally, in matters concerning teaching and learning. This is partly due to the paucity of comparable quantitative indicators. The challenges are even greater when benchmarking is at course (program) level. As part of an Australian Learning and Teaching Council fellowship (Benchmarking partnerships for graduate employability), a process was designed to enable course leaders to engage in collaborative and confidential benchmarking at course level, with a particular focus on graduate employability (or, more specifically, the assurance of graduate capability development and achievement). Among the 24 benchmarking partners were three course leaders in undergraduate journalism. This paper describes their collective experiences and some of the outcomes of the benchmarking exercise. It also highlights some of the challenges of benchmarking in a discipline where graduates may follow a range of career paths, and where technology means professional practice is evolving at a very rapid pace. Given these underpinning uncertainties, discussions around employability and appropriate graduate capabilities are best had face to face with adequate time for establishing common understandings. This has also been a focused way of building capacity and scholarly networking.

Risk management, player welfare and privacy : player development managers and dilemmas for employee relations in Australian football league clubs

This paper reports on one aspect of a research project that was funded by the Australian Football League (AFL) to explore the emergence and evolution of a ‘professional identity’ for AFL footballers. The research was informed by Foucault's later work on the care of the Self to focus on the ways in which player identities are governed by coaches, club officials, and the AFL Commission/Executive; and the manner in which players conduct themselves in ways that can be characterised as professional - or not. The paper explores the roles of Player Development Managers (PDMs) in emerging processes of risk and player management. These roles increasingly involve PDMs in risk management practices and processes that can be seen as intrusive in players’ lives. These risk management processes raise a number of concerns about player privacy and the rights of Clubs to know what their employees are up to away from the workplace.

I'm the slice of pie that's ostracised.... : Foucault's technologies, and personal agency, in the voice of women who are homeless, Adelaide, South Australia

In contrast to the international research (particularly in the United Kingdom and North America), much of the Australian literature regarding homelessness to date omits the perspective of people who are homeless. In contributing to the fledgling Australian literature in the field, the following article adopts a secondary approach to the data analysis of original research. When analysed, the voices of homeless women from an agency in Adelaide, South Australia exhibit elements of both Foucault’s technologies of domination and the self. While the results show that the women do have a powerful sense of the broader external issues exerted on them (reflecting both technologies of domination and the self), the analysis also reveals ambiguities in their responses. Apparent in the voice of homeless women is a sense of personal agency which appears to be absent in Foucault’s technologies. By considering the viewpoints of homeless women, various policy implications can also be drawn. Indeed, this is one of the motivations of the article, namely to inject into policy debate and development the voices of the people most adversely affected by it. The policy implications of the women’s voices centre around the desire to be included rather than remain on the margins, the need for supportive relationships, the necessity to take small steps to independent living, and the need for more affordable, independent housing.

The development of 20 microsatellite loci for the Australian marine mollusk, Donax deltoides, through next generation DNA sequencing

 Next Generation DNA sequencing was used to develop a suite of microsatellite markers for the marine mollusk, Donax deltoides. A total of 20 polymorphic loci were identified and 12 characterized using 30 individuals from a single population (Venus Bay) in south eastern Australia. We observed moderate to high genetic variation across most loci (mean number of alleles per locus = 7.3; mean heterozygosity = 0.633) with only a single locus (Ddel32) displaying significant deviation from Hardy–Weinberg equilibrium. Marker independence was confirmed with tests for linkage disequilibrium, however two loci were found to be influenced by null alleles. The 10 viable markers characterized in the present study provide a valuable resource for future population genetic assessments and fisheries management of D. deltoides in Australia.

Challenges in the development of standards for synthetic turf for Australian football and cricket

Given the escalating drought conditions in Australia, synthetic surfaces have recently been explored as a viable surface option for community-level Australian football–cricket ovals. The vast majority of Australian football ovals are transformed into cricket pitches during the football off-season and hence the characteristics of both sports had to be duly considered in the development of standards that could be tested in a laboratory setting, for a synthetic turf surface. This paper describes the data collection and test methods undertaken in the development of the standards for synthetic surface use in Australian football and cricket. The paper also discusses the issues and challenges encountered during the development of standards for multi-sport synthetic surfaces to ensure player safety while maintaining the performance characteristics of both sports. Surface property and ball interaction tests were undertaken on natural playing surfaces, both in situ and in the laboratory to determine the properties of the current playing surface for each sport. This paper highlights the importance of careful consideration of the characteristics of both games and the use of equipment from both sports in the testing methods. The standards described in this paper have now been accepted by the Australian Football League and Cricket Australia and the product approval process and use of synthetic surfaces for Australian football and cricket is imminent.
