- Description: Aging is associated with diffuse impairments in vascular endothelial function and traditional aerobic exercise is known to ameliorate these changes. High intensity interval training (HIIT) is effective at improving vascular function in aging men with existing disease, but its effectiveness remains to be demonstrated in otherwise healthy sedentary aging. However, the frequency of commonly used HIIT protocols may be poorly tolerated in older cohorts. Therefore, the present study investigated the effectiveness of lower frequency HIIT (LfHIIT) on vascular function in a cohort of lifelong sedentary (SED; n = 22, age 62.7 +/- 5.2 years) men compared with a positive control group of lifelong exercisers (LEX; n = 17, age 61.1 +/- 5.4 years). The study consisted of three assessment phases; enrolment to the study (Phase A), following 6 weeks of conditioning exercise in SED (Phase B) and following 6 weeks of low frequency HIIT in both SED and LEX (LfHIIT; Phase C). Conditioning exercise improved FMD in SED (3.4 +/- 1.5% to 4.9 +/- 1.1%; P < 0.01) such that the difference between groups on enrolment (3.4 +/- 1.5% vs. 5.3 +/- 1.4%; P < 0.01) was abrogated. This was maintained but not further improved following LfHIIT in SED whilst FMD remained unaffected by LfHIIT in LEX. In conclusion, LfHIIT is effective at maintaining improvements in vascular function achieved during conditioning exercise in SED. LfHIIT is a well-tolerated and effective exercise mode for reducing cardiovascular risk and maintaining but does not improve vascular function beyond that achieved by conditioning exercise in aging men, irrespective of fitness level.

- Description: This review explores the differences between agility in invasion sports (defined as including reactive decision-making) and change-of-direction speed (CODS), and highlights the implications for training. Correlations between agility tests and CODS tests indicate that they represent independent skills. Agility tests discriminate higher-from lower-standard athletes better than CODS tests, indicating that the cognitive element of agility is important to performance. Training studies have shown that the development of strength qualities can transfer to gains in CODS, but this has never been shown for agility. There is some evidence that the importance of physical qualities is greater for CODS than for agility. It was concluded that the reactive element should be included in agility training, testing and research. While there appears to be no research evidence for the benefits of strength and power training, there is some support for the use of small-sided games for improving agility.

- Description: Estimate the amount of alcohol advertising in sport vs. non-sport programming in Australian free-to-air TV and identify children's viewing audience composition at different times of the day. Alcohol advertising and TV viewing audience data were purchased for free-to-air sport and non-sport TV in Australia for 2012. We counted alcohol advertisements in sport and non-sport TV in daytime (6 am-8.29 pm) and evening periods (8.30 pm-11.59 pm) and estimated viewing audiences for children and young adults (0-4 years, 5-13 years, 14-17 years, 18-29 years). During the daytime, most of the alcohol advertising (87%) was on sport TV. In the evening, most alcohol advertising (86%) was in non-sport TV. There was little difference in the mean number of children (0-17 years) viewing TV in the evening (N = 273,989), compared with the daytime (N = 235,233). In programs containing alcohol advertising, sport TV had a greater mean number of alcohol adverts per hour (mean 1.74, SD = 1.1) than non-sport TV (mean 1.35, SD = .94). Alcohol advertising during the daytime, when large numbers of children are watching TV, is predominantly in free-to-air sport TV. By permitting day-time advertising in sport programs and in any programs from 8.30 pm when many children are still watching TV, current regulations are not protecting children from exposure to alcohol advertising.

- Description: We introduce a subfamily of additive enlargements of a maximally monotone operator. Our definition is inspired by the early work of Simon Fitzpatrick. These enlargements constitute a subfamily of the family of enlargements introduced by Svaiter. When the operator under consideration is the subdifferential of a convex lower semicontinuous proper function, we prove that some members of the subfamily are smaller than the classical epsilon-subdifferential enlargement widely used in convex analysis. We also recover the epsilon-subdifferential within the subfamily. Since they are all additive, the enlargements in our subfamily can be seen as structurally closer to the epsilon-subdifferential enlargement.

- Description: This thesis seeks to develop a critical understanding of the impact of a particular Community Renewal project on the residents. The Wendouree West Community Renewal was part of a broader Victorian state government intervention, Neighbourhood Renewal, which worked ‘on’ communities identified as disadvantaged. The study investigated the experiences of key residents, along with those of the author, during the period 2001-2013. The main contention is that Wendouree West Community Renewal project colluded with the welfare sector to impose a hegemonic and alien set of understandings on the community. This study is passionate; it takes a stance that is unashamedly political, ideological and partisan. Its key premise is that government interventions of this kind are damaging to communities like the one investigated. The Wendouree West experience promoted a three-fold residualisation: at the level of a ‘breaking down’ of local economies; an undermining of formal and informal education at a community level; and a manipulation of understandings of place, belonging and community that resulted in the imposition of a fake ’aspirational community’ in Wendouree West. The impact of this three-fold residualisation was a deep stigmatisation of Wendouree West as a ‘non-place’ (Auge, 2008), enabling its ultimate ghettoisation, both within the broader context of the regional city of which Wendouree West forms a small part, and within the understandings of residents themselves. This thesis represents struggle at a number of levels: the struggle of the residents to push back against a hegemonic intervention; the struggle of a scholar to make sense of his own role within the action; and the struggle of how to represent the residents’ stories in ways that are powerful and ‘truthful’ within the context of a PhD thesis. ii The ‘critical hope’ of this work is that the residents are able to push back against this program through acts of resistance and that community organising, in the style of the American radical Saul Alinsky, may represent a possible longer term means for empowerment and self-determination.

- Description: A general nonlinear regularity model for a set-valued mapping F : X x R+ paired right arrows Y, where X and Y are metric spaces, is studied using special iteration procedures, going back to Banach, Schauder, Lyusternik, and Graves. Namely, we revise the induction theorem from Khanh [J. Math. Anal. Appl., 118 (1986), pp. 519-534] and employ it to obtain basic estimates for exploring regularity/openness properties. We also show that it can serve as a substitution for the Ekeland variational principle when establishing other regularity criteria. Then, we apply the induction theorem and the mentioned estimates to establish criteria for both global and local versions of regularity/openness properties for our model and demonstrate how the definitions and criteria translate into the conventional setting of a set-valued mapping F : X paired right arrows Y. An application to second-order necessary optimality conditions for a nonsmooth set-valued optimization problem with mixed constraints is provided.

- Description: Objectives: To review how enablement is conceptualized and practiced in primary health care and to explore the factors that influence patient enablement in this setting. Method: A narrative integrative literature review was undertaken. Results: Twenty-four articles specifically relating to enablement in primary health care were identified. Three literature reviews, 4 qualitative studies, and 17 quantitative studies were included in the analysis. Conclusions: In the primary health care setting, the concept of enablement is well defined as an outcome measure of quality. The literature exploring the practice of enablement is sparse, but 2 randomized controlled trials suggest enablement is linked to better outcomes for patients with asthma and diabetes. Primary factors influencing enablement included the practitioners’ open communication style, the degree to which the practitioner is patient centered, and longer consultations. Other factors found to be associated with enablement were the presenting health issue, general state of health, ethnicity, the patient’s own coping strategies and degree of independence, and socioeconomic status. The association between enablement and patients’ expectations and satisfaction is less clear. The majority of research on enablement was carried out among general practitioners. Further research into the degree to which patients are enabled by a wider range of health care providers is needed. Additional qualitative research would provide a deeper understanding of the attributes of enablement in the primary health care setting.

- Description: This research project concerns itself with the human desire for control, order and perfection through an investigation of our attempts to control nature. The museum case acts as a metaphor for this attempt to organise the natural world in a logical and systematised fashion. In my artwork I aim both to present and to challenge this imposition of order and control through my interpretation of the Glass Flower display at the Harvard Natural History Museum, formally known as the Ware Collection of Blaschka Glass Models of Plants. This examination of the Glass Flowers and their visual representation has been informed and challenged by an understanding of their paradoxical and enigmatic position between science and art, nature and culture. In my artwork this ambivalence about the Flowers as objects of scientific certainty, and about the museum as a site of control, is expressed as an increasing tension between representation and abstraction, the precise rendition of form and the visibility of the medium of oil paint. Together with the exegesis this project explores issues of museology and the nature of collected and displayed objects, particularly these Glass Flowers which were purpose-made for the museum. My visual work responds to the museum environment in ways which both embrace its aesthetic and question its attitudes to nature. In doing so, it reflects the paradoxical nature of the Flowers and the nature of seeing itself, creating a visual world in which ambiguities of scale, location and even subject undermine our certainty of what we see, creating a magical space out of the ordered world of the museum.

- Description: Traumatic brain injury (TBI) is the leading cause of death in alpine skiing. It has been found that helmet use can reduce the incidence of head injuries between 15% and 60%. However, knowledge on optimal helmet performance criteria in World Cup alpine skiing is currently limited owing to the lack of biomechanical data from real crash situations. Purpose: This study aimed to estimate impact velocities in a severe TBI case in World Cup alpine skiing. Methods: Video sequences from a TBI case in World Cup alpine skiing were analyzed using a model-based image matching technique. Video sequences from four camera views were obtained in full high-definition (1080p) format. A three-dimensional model of the course was built based on accurate measurements of piste landmarks and matched to the background video footage using the animation software Poser 4. A trunk-neck-head model was used for tracking the skier's trajectory. Results: Immediately before head impact, the downward velocity component was estimated to be 8 m.s(-1). After impact, the upward velocity was 3 m.s(-1), whereas the velocity parallel to the slope surface was reduced from 33 m.s(-1) to 22 m.s(-1). The frontal plane angular velocity of the head changed from 80 radIsj1 left tilt immediately before impact to 20 rad.s(-1) right tilt immediately after impact. Conclusions: A unique combination of high-definition video footage and accurate measurements of landmarks in the slope made possible a high-quality analysis of head impact velocity in a severe TBI case. The estimates can provide crucial information on how to prevent TBI through helmet performance criteria and design.

- Description: Substation plays an important role in power system communications for safe and reliable operation of entire power networks. Substation communication networks are connected with various substation intelligent electronic devices (IEDs), which is substation systems lifeblood and the system availability is decided by its real-Time performance. International Electro-Technical Commission (IEC) has been developed the standards based on object-oriented technologies for substation automation. IEC 61850 protocol has been applied widely in substation communication applications. It presents new challenges to realtime performance simulation and testing of protective relays. In this paper, an optimized network engineering tool (OPNET) or Riverbed modeler simulation tool/ software has been used for the modeling of IED in substation level network. Based on the simulation results, different types of data stream have been discussed, such as, periodic data stream, random data stream and burst data steam. The typical studies using these models, to construct substation automation system (SAS) network on the OPNET modeler or Riverbed modeler was made to reveal the impact of each affecting parameter or factor to the real-Time performance of substation communications system, which is also incorporated in this report.

- Description: Continuous, remote monitoring of patients using wearable sensors can facilitate early detection of many conditions and can help to manage the growing healthcare crisis worldwide. A remote patient monitoring application consists of many emerging services such as wireless wearable sensor configuration, patient registration and authentication, collaborative consultation of doctors, storage and maintenance of electronic health record. The provision of these services requires the development and maintenance of a remote healthcare monitoring application (HMA) that includes a body area wireless sensor network (BASWN) and Health Applications (HA) to detect specific health issues. In addition, the deployment of HMAs for different hospitals is not easily scalable owing to the heterogeneous nature of hardware and software involved. Cloud computing overcomes this aspect by allowing simple and easy maintenance of ICT infrastructure. In this work, we report a realtime- like cloud based architecture known as Assistive Patient monitoring cloud Platform for Active healthcare applications (AppA) using a delegate pattern. The built AppA is highly scalable and capable of spawning new instances based on the monitoring requirements from the health care providers, and is aligned with scalable economic models.

- Description: Large scale integration of wind power can be deterred by congestion following an outage that results in constrained network capacity. Post outage congestion can be mitigated by the application of event control strategies; however they may not always benefit large wind farms. This paper investigates this problem in detail and proposes an advanced mathematical framework to model network congestion as functions of stochastic limits of network assets to capture post contingency risk of network congestion resulting through the constrained network capacity that limits high penetration of wind. The benefit of this approach is that it can limit the generation to be curtailed or re-dispatched by dynamically enhancing the network latent capacity in the event of outages or as per the need. The uniqueness of the proposed mathematical model is that it converts conventional thermal constraints to dynamic constraints by using a discretized stochastic penalty function with quadratic approximation of constraint relaxation penalty. The case study results with large and small network models suggest that the following an outage, wind utilization under dynamic line rating can be increased considerably if the wind power producers maintain around a 15% margin of operation.

- Description: Dipeptide (Leu-Leu) and nitrate transport activities of 26 Arabidopsis NPF (NRT1/PTR Family) proteins were screened in Saccharomyces cerevisiae and Xenopus laevis oocytes, respectively. Dipeptide transport activity has been confirmed for 2 already known dipeptide transporters (AtNPF8.1 and AtNPF8.3) but none of the other tested NPFs displays dipeptide transport. The nitrate transport screen resulted in the identification of two new nitrate transporters, AtNPF5.5 and AtNPF5.10. The localization of the mRNA coding for NPF5.5 demonstrates that it is the first NPF transporter reported to be expressed in Arabidopsis embryo. Two independent homozygous npf5.5 KO lines display reduced total nitrogen content in the embryo as compared to WT plants, demonstrating an effect of NPF5.5 function on the embryo nitrogen content. Finally, NPF5.5 gene produces two different transcripts (AtNPF5.5a and AtNPF5.5b) encoding proteins with different N-terminal ends. Both proteins are able to transport nitrate in xenopus oocytes.

- Description: When the Nobel prize-winning economist Joe Stiglitz visited Australia in 2010 he commended the Rudd Government’s policy response to the Global Financial Crisis as a proper and effective pre-emptive measure. The stimulus, which staved off any creeping sign of recession, bore a considerable Treasury imprint; and it could be said that the official family of economic advisers, that is, the Treasury and the Reserve Bank of Australia, were in their concerted action never so Keynesian in practice. It is appropriate then to visit the Keynesian revolution in post-war Australia recalling that three of the mandarins, Roland Wilson, John Crawford and H.C. ‘Nugget’ Coombs, were professionally trained economists. Moreover, as J.K. Galbraith reminds us, the Keynesian revolution was really a ‘mandarin revolution’, that is, an intellectually powered one.

- Description: This paper analyses Australian rural accountant's attitudes and levels of satisfaction with continuing professional development (CPD), based on whether the CPD was delivered by a professional accounting body in a rural or metropolitan area. The paper responds to prior research that finds rural accountants are dissatisfied with professional accounting bodies [Rural and regional Australian public accounting firm services: Service provision, concerns and tensions. Australian Accounting Review, 23(23), 163–176]. Findings of a survey to which 156 rural accountants responded were that when CPD is delivered into the rural areas, there are greater levels of CPD satisfaction. The study also found that cost was significantly better for rural-delivered CPD and that when more rural-based CPD was attended differences became more significant across a number of satisfaction measures. The findings have important implications for both rural accountants and professional accounting bodies. © 2015 Taylor & Francis.

Becoming "Brave and Gallant" : Decolonising the myths of Burke and Wills; Cross-cultural exchanges and the co-production of knowledge during the Victorian Exploring Expedition and the subsequent Relief Expeditions

- Description: The history of the Victorian Exploring Expedition (VEE), also known as ‘Burke and Wills’, has commonly been told as a story of ‘brave and gallant men’ who ventured into an unfamiliar landscape and became victims of the ‘ghastly blank’ interior of Australia. Visual artists and historians have memorialised these men as solo-hero explorers who sacrificed their youth and life potential for the sake of Australian nation. The myth of Burke and Wills is a constructed narrative and symbol of glory and achievement that denies the involvement of significant others in exploration and geographical knowledge creation. The path the VEE created through the centre of Australia opened up the broader continent for rapid colonisation and imperial expansion. The tragic legacy of the deaths of Burke and Wills is part of the Australian identity, however, some major aspects of the VEE successes and failures have been sidelined, silenced and even completely ignored in many historical accounts. The historical and visual art accounts that contributed to the memorialisation of Burke and Wills often denied the involvement of other exploration team members, the relief expeditions who went in search of the missing explorers, various intermediaries, guides, go-betweens and significantly Aboriginal peoples’ close involvement and or resistance to interior exploration. Yandruwandha people have been remembered as a friendly and accommodating community who assisted the explorers in their last days and who cared for John King. Within the archives and social memories are examples of agency, power, resistance, and varied perspectives of Burke and Wills. This ethnographic history asks why relations between the explorers, Aboriginal peoples and landscape have been told the way they have and provides examples of encounter and exchange, mutual adaptation and the co-production of knowledge as a way to decolonise the myths of Burke and Wills.

- Description: Newly democratising states experience challenges in reconciling 'traditional' or 'customary' dispute resolution practices with newly established state-based legal systems based on the rule of law. For Timor- Leste, these tensions are pronounced in continuing debates concerning the killing or injuring of women accused of witchcraft. Defences of extrajudicial punishments tend to conflate democracy with local support and fail to deal with the key institutions of democratic systems, including the rule of law, political equality, and civil rights. In Timor- Leste's case, where equality and social rights were incorporated into the Constitution as fundamental governmental obligations, localised extrajudicial punishments threaten internal and external state legitimacy and highlight the difficulties of ensuring the primacy of state-based institutions. Extrajudicial punishments challenge Timor-Leste's capacity to consolidate new liberal democratic political institutions. © 2015, GIGA German Institute of Global and Area Studies. All rights reserved.
