  • Description: The purpose of this paper is to summarise the methodology for the 5th International Consensus Conference on Concussion in Sport. The 18 months of preparation included engagement of a scientific committee, an expert panel of 33 individuals in the field of concussion and a modified Delphi technique to determine the primary questions to be answered. The methodology also involved the writing of 12 systematic reviews to inform the consensus conference and submission and review of scientific abstracts. The meeting itself followed a 2-day open format, a 1-day closed expert panel meeting and two additional half day meetings to develop the Concussion Recognition Tool 5 (Pocket CRT5), Sport Concussion Assessment Tool 5 (SCAT5) and Child SCAT5.

  • Description: Although the proapoptotic BH3-only protein, Bim, is required for deletion of autoreactive thymocytes, Bim-deficient mice do not succumb to extensive organ-specific autoimmune disease. To determine whether other BH3-only proteins safeguard tolerance in the absence of Bim, we screened mice lacking Bim as well as other BH3-only proteins. Most strains showed no additional defects; however, mice deficient for both Puma and Bim spontaneously developed autoimmunity in multiple organs, and their T cells could transfer organ-specific autoimmunity. Puma- and Bim-double-deficient mice had a striking accumulation of mature, single-positive thymocytes, suggesting an additional defect in thymic deletion was the basis for disease. Transgenic mouse models of thymocyte deletion by peripheral neoantigens confirmed that the loss of Bim and Puma allowed increased numbers of autoreactive thymocytes to escape deletion. Our data show that Puma cooperates with Bim to impose a thymic-deletion checkpoint to peripheral self-antigens and cement the notion that defects in apoptosis alone are sufficient to cause autoimmune disease.

  • Description: This paper focuses on what is known internationally from research about some aspects of men’s learning. It explores the similar and different factors that shape men’s attitudes towards learning in diverse national and cultural contexts. It also identifies some possible parallels (and differences) between the experiences, participation and outcomes in education of men and boys. The paper proceeds to make a case for recognising and addressing the factors that affect gender parity in educational contexts, including Australia, in which several tertiary outcome measures tend to be skewed towards girls and women. The paper forms part of background research for Phase 1 (in several Anglophone nations) of a major international research project into men's learning in community settings that includes several Australian study sites.

  • Description: Biomechanical studies of concussions have progressed from qualitative observations of head impacts to physical and numerical reconstructions, direct impact measurements, and finite element analyses. Supplementary to a previous study, which investigated maximum principal strain, the current study used a detailed finite element head model to simulate unhelmeted concussion and no-injury head impacts and evaluate the effectiveness of various tissue-level brain injury predictors: strain rate, product of strain and strain rate, cumulative strain damage measure, von Mises stress, and intracranial pressure. Von Mises stress was found to be the most effective predictor of concussion. It was also found that the thalamus and corpus callosum were brain regions with strong associations with concussion. Tentative tolerance limits for tissue-level predictors were proposed in an attempt to broaden the understanding of unhelmeted concussions. For the thalamus, tolerance limits were proposed for a 50% likelihood of concussion: 2.24 kPa, 24.0 s-1, and 2.49 s-1 for von Mises stress, strain rate, and the product of strain and strain rate, respectively. For the corpus callosum, tolerance limits were proposed for a 50% likelihood of concussion: 3.51 kPa, 25.1 s-1, and 2.76 s-1 for von Mises stress, strain rate, and the product of strain and strain rate, respectively. © 2015 Human Kinetics, Inc.

  • Description: Objective: Concussion is a prevalent brain injury in sport and the wider community. Despite this, little research has been conducted investigating the dynamics of impacts to the unprotected human head and injury causation in vivo, in particular the roles of linear and angular head acceleration. Setting: Professional contact football in Australia. Participants: Adult male professional Australian rules football players participating in 30 games randomly selected from 103 games. Cases selected based on an observable head impact, no observable symptoms (eg, loss-of-consciousness and convulsions), no on-field medical management and no injury recorded at the time. Primary and secondary outcome measures: A data set for no-injury head impact cases comprising head impact locations and head impact dynamic parameters estimated through rigid body simulations using the MAthematical DYnamic MOdels (MADYMO) human facet model. This data set was compared to previously reported concussion case data. Results: Qualitative analysis showed that the head was more vulnerable to lateral impacts. Logistic regression analyses of head acceleration and velocity components revealed that angular acceleration of the head in the coronal plane had the strongest association with concussion; tentative tolerance levels of 1747 rad/s2 and 2296 rad/s2 were reported for a 50% and 75% likelihood of concussion, respectively. The mean maximum resultant angular accelerations for the concussion and no-injury cases were 7951 rad/s2 (SD 3562 rad/s2) and 4300 rad/s2 (SD 3657 rad/s2), respectively. Linear acceleration is currently used in the assessment of helmets and padded headgear. The 50% and 75% likelihood of concussion values for resultant linear head acceleration in this study were 65.1 and 88.5 g, respectively. Conclusions: As hypothesised by Holbourn over 70 years ago, angular acceleration plays an important role in the pathomechanics of concussion, which has major ramifications in terms of helmet design and other efforts to prevent and manage concussion.

The biopsychosocial impact of Autism on families and the contribution of solar irradiance to its aetiology

  • Description: Autism Spectrum Disorder (ASD) is a lifelong disorder of unknown aetiology. A recent hypothesis is that a lack of Vitamin D is implicated in either the aetiology or maintenance of ASD. The human body synthesises Vitamin D from Ultraviolet-B (UVB) radiation found in sunlight. It follows that greater exposure to sunlight hours may be related to decreased rates of ASD. There are no interventions that target the causes of ASD rather therapies address either its symptoms or its comorbidities. ASD not only affects individuals, it also has an impact on their families. Family members have experienced social, occupational and personal costs associated with their child’s ASD which can result in parental separation or divorce. While researchers have established some of the factors which contribute to the impact on families, this research has not addressed families living in regional areas nor have empirical studies used domain-specific scales. The aims in this thesis were: Study 1) to determine whether the prevalence rates of ASD vary as a function of exposure to sunlight by reviewing reported prevalence rates by latitude where, the greater the distance from the equator, the higher the expected prevalence rates; Study 2) to conduct interviews with parents and caregivers of children with ASD who live in a regional area to determine the factors which affect them and those which might protect them; and Study 3) use the interview data to develop domain specific measures and test a model of living with a child with ASD. The results of Study 1 revealed that there is an increase in the prevalence of ASD as distance from the equator increases lending some support to the hypothesis that Vitamin D is implicated in ASD. The 16 interviews conducted in Study 2 revealed seven themes: impact on finances; family life; child’s health and behaviour, and schooling; child’s future; limited support, and regional living. In Study 3, with 178 participants, domain-specific scales were developed to test a model of the impact of living with a child with ASD. Resilience manifested by social support and coping strategies, explained 54% of the variance in impact of living with a child with ASD which, was operationalised by financial and relationship costs, social impact and feelings. Family life as assessed in this thesis, is significantly impacted by living with a child with ASD. The implications of these findings are discussed, especially around the need for greater exposure to outdoor activities and hence sunlight for children with ASD, more regional facilities and assistance for families, the importance of educational interventions for the public as well as enhancing levels of family resilience, as operationalised by support and coping strategies. Limitations of the studies and future research are discussed.

The blurred boundary between professional and lay home nursing knowledge and practice in New Zealand, 1900-1935

  • Description: In New Zealand, the state registration of nurses was instituted in 1901. This was a marker that nursing had achieved professional status. Although many registered nurses (RNs) worked in private practice or as district nurses in people's homes, lay home nurses had an essential role in caring for the sick. This article reports a comparative analysis of information available to lay home nurses in domestic health guides with information for RNs in professional nursing textbooks, for the period 1900–1935. It shows that despite RNs' professional status, domestic health guides gave more detailed information than nursing textbooks on many subjects until the end of the research time period. The boundary between registered and lay home nurses' knowledge and practice was therefore blurred. Exploring this indistinct boundary challenges understandings about the clear division between professional and lay knowledge and practice. This has particular relevance in a time when health systems increasingly depend on care provided in the home by family members. Home nursing has always been a crucial component in any system for the care of the sick. Historically, caring for people at the end of life or those with chronic and acute illnesses depended largely on the commitment of untrained women, nursing their own family members at home and supporting neighbors to care for the ill in other households.

The Body as Fiction / Fiction as a Way of Thinking: On Writing A Short (Personal) History of the Bra and its Contents

  • Description: This thesis uses fiction as a research technology for investigating and thinking about issues to do with bodies and knowledge at the cusp of the 20th and 21st centuries. It includes sample material from a novel in progress -- A Short (Personal) History of the Bra and its Contents -- to illustrate some of the unique outcomes of this approach to exploring cultural history and writing cultural criticism. One of the advantages of fiction is that it allows me to create a discursive field in which it is possible for the very wide range of issues raised by my topic to coexist, work off each other and cross-fertilise. These include ideas regarding gender, sexuality, nurture and subjectivity; issues to do with the implants controversy, the cancer industry and the corporatisation of medicine (and hence various current debates within science and medicine); as well as movements in fashion history and popular culture -- all of which contribute to making up the datasphere in which and through which we continually reproduce ourselves as subjects.

  • Description: This paper celebrates the life of a businessman and central banker who, in the depression years, outshone and prevailed over both Theodore and Jack Lang. One member of the Scullin Cabinet, the fiery radical Frank Anstey recalled that 'with his seven year tenure in his pocket he was more than ever Prime Minister and the elected government was only the tube through which he issued orders'. The puzzle then is why Gibson has not received the coverage and attention that he deserves. While there has been a brief memoir of Gibson by Schedvin, no biography of him exists. Just after Gibson dies in 1934 the Commonwealth Bank, with the support of Gibson's Melbourne-based business and banking associates, was intent upon commissioning a short biography with University of Melbourne historian Sir Ernest Scott (1867-1939) assigned to undertake the task. At the same time on one of Gibson's daughters, Phyllis, wrote a doting, but incomplete, memoir of her father. The draft was never completed nor circulated but it led to an interesting sequel.

  • Description: This paper revisits the matter of attracting students to study economics, an issue that faces every Australian university economics department. While the Australian economy has been in a boom phase for some period it has not led to a relative increase in economic degree enrolments for local universities. While some of the Go8 universities have seen a steady increase in economics degree enrolments between 1995 and 2007, the national picture, taken over a longer period, reveals that economic degree enrolments as a percentage of the overall student population is still falling. The paper concludes with the shy hope that, apart from improvement to the syllabus and teaching methodologies, the marked economic slowdown might elicit an increase in student interest in economics. The paper closes by suggesting that now might be an appropriate time for the regimen of the ideal economics degree offered by Australian universities to be re-examined.

  • Description: Abstract: National statistics indicate the ongoing challenge of catering for the unique needs of students with Autism Spectrum Disorder (ASD) within the context of inclusive education. Higher rates of difficulty and poorer outcomes are experienced by this cohort when compared to both the general population and others within the disability sector. The perspectives of educators from a variety of roles were examined to identify factors impacting upon the educational experience of high-functioning students with ASD to determine how they could be supported more effectively. Findings indicate despite extensive educational experience and considerable knowledge of ASD, many educators lack an understanding of how to identify individual student needs, and also of specific impacts of ASD and appropriate supportive strategies. Emerging from the data, the Bridges and Barriers Model of Support (BBMS) provides inclusive school communities with a framework for planning a shared understanding of student strengths, identified challenges, supportive strategies and specific targets for success.

The Broad-toothed Rat Mastacomys fuscus in Victoria : an update on research, occurrence records and future threats

  • Description: The Broad-toothed Rat (BTR) Mastacomys fuscus is a native murid rodent found in high rainfall areas of NSW, ACT, Victoria and Tasmania. It is classed as Vulnerable in each state, the ACT and by the Commonwealth. It is herbivorous, feeding on grasses (especially Poa spp.) and sedges. In Victoria, it occurs from sea level to the Alpine National Park but in patches and generally in low numbers. There were few scientific reports on BTRs in Australia until the 1960s when fossil and sub-fossil remains of the species were reported from several locations, including western Victoria and south-eastern South Australia, suggesting the species was once more widespread than it is today. Research in the 1960s described the habitat and biology of the BTR in Kosciuszko National Park and in 1971 a significant paper added several new locations of living BTR colonies in Victoria. Subsequent work located more sites, but little was published until the last 20 years, when threats to the future of the species and a reduction in its distribution were described. The BTR has thus undergone cycles of apparent abundance and occurrence. Climate change and other anthropogenic threats make the future survival of the BTR in Victoria uncertain.

  • Description: The Buchan Caves Reserve is some 360km east of Melbourne, near the township of Buchan. The Reserve is jointly managed by Parks Victoria and the Gunaikurnai Land and Water Aboriginal Corporation. It contains a visitor centre and facilities for overnight camping and day visitors. Within the reserve lies a honeycomb of caves with limestone formations – but there are only two show caves, Royal Cave (see Fig.3.1) and Fairy Cave (see Fig.3.2), and guided tours are conducted year round. The Buchan Caves Reserve falls within the Krauatungalung language area (Clark, 1998a: 189-190). This language or dialect, is one of five normally referred to as the ‘Ganai nation’ or ‘Kurnai nation’, a cluster of dialects sharing linguistic, social, cultural, political, and family associations.
