    This study focuses on the development of a Design Framework for Higher Education Curriculum Ecosystem design. The study views the world as a digital ecosystem where the physical and the virtual are fully intertwined and function through integrated social and technical architecture working together in a seamless mesh that is persistent and pervasive. This digital ecosystem is an open, flexible, demand driven, self-organising, collaborative environment. It has enhanced individuals’ abilities to connect with other people, share ideas, work collaboratively and form communities. This has inevitably impacted on educational practice in Higher Education. The thesis draws together educational theories, curriculum designs, and concepts drawn from ecological psychology, cognitive apprenticeship, distributed cognition and activity theory, and extends them through the application of a Complexity Science lens. A Complexity Science perspective views the world as comprised of Complex Adaptive Systems. This study explores how authentic learning processes can be scaffolded within a Complex Adaptive System. The iterative development and refinement, through three iterations over six years, of a curriculum ecosystem for a Built Environment Degree Program is used as a case study for the development of a Higher Education curriculum ecosystem exemplar. A Design Framework for a Curriculum Ecosystem for Higher Education which has emerged through this process is presented

    Background: Recommendations for the echocardiographic assessment of left ventricular (LV) mass in the athlete suggest the use of the linear method using a two-tiered classification system (2TC). The aims of this study were to compare the linear method and the area-length (A-L) method for LV mass in elite rugby football league (RFL) athletes and to establish how any differences impact the classification of LV geometry using 2TC and four-tier (4TC) classification systems. Methods: Two hundred and twenty (220) male RFL athletes aged 25 ± 5 (14–34 years) were recruited. All athletes underwent echocardiography and LV mass was calculated by the American Society of Echocardiography (ASE) corrected Linear equation (2D) and the A-L method. Left ventricular mass Index (LVMi) was used with relative wall thickness to determine geometry in the 2TC and with concentricity and LV end diastolic volume index for the 4TC. Method specific recommended cut-offs were utilised. Results: Higher values of absolute (197 ± 34 vs. 181 ± 34 g; p < 0.0001) and indexed (92 ± 13 vs. 85 ± 13 g/m2; p < 0.0001) measures of LV mass were obtained from A-L compared to the linear method. Normal LV geometry was demonstrated in 98.2% and 80% of athletes whilst eccentric hypertrophy in 1.4% and 19.5% for linear and A-L respectively. Both methods provided 0.5% as having concentric remodelling and 0% as having concentric hypertrophy. Allocation to the 4TC resulted in 97% and 80% with normal geometry, 0% and 8.6% with eccentric dilated hypertrophy, 0% and 7.7% with eccentric non-dilated hypertrophy, 1.4% and 0.5% with concentric remodelling and 1.4% and 3% with concentric non-dilated hypertrophy for linear and A-L methods respectively. No participants had concentric dilated hypertrophy from either methods. Conclusion: The linear and A-L method for calculation of LV mass in RFL athletes are not interchangeable with significantly higher values obtained using A-L method impacting on geometry classification. More athletes present with eccentric hypertrophy using 2TC and eccentric dilated/non-dilated using 4TC. Further studies should be aimed at establishing the association of A-L methods of LV mass and application of the 4TC to the multi-factorial demographics of the athlete

    Does the Dark Triad predict prejudice?: The role of machiavellianism, psychopathy, and narcissism in explaining negativity toward asylum seekers

    Objective: Personality has a long history of being linked to attitudes toward various social groups, but little research has explored how darker aspects of personality might contribute to social attitudes. In this article, we explore the role of the ominous personality traits in the Dark Triad (narcissism, Machiavellianism, and psychopathy) in accounting for prejudice, in the specific case of antipathy toward asylum seekers. Method: A community sample of 173 Australians (Mage = 23.37 years, SD = 7.88; 74% females) responded to measures of classical and modern explicit attitudes and implicit attitudes toward this group. This study used a correlational research design. Results: The sample reported neutral explicit attitudes (both classical and modern) but implicit attitudes were negative. Classical attitudes were less negative than modern attitudes. Multiple hierarchical regression analyses revealed political conservatism and psychopathy predicted modern explicit attitudes while political conservatism and Machiavellianism predicted classical attitudes. Narcissism was unrelated to all attitudes, and none of the Dark Triad personality traits were related to implicit attitudes. Conclusion: The implications of the relationships between sub‐clinical personality traits and social attitudes are discussed in reference to intervening with punitive attitudes towards this vulnerable social group. This article presents new evidence that Machiavellianism is related to classic attitudes, and provides more evidence that psychopathy is related to modern attitudes. Finally, this article adds to the scarce literature on implicit attitudes towards asylum seekers

    The ‘sober eye’ : Examining attitudes towards non-drinkers in Australia

    Background The proportion of Australians who choose not to drink alcohol has increased in recent years; yet, non-drinkers report experiences of stigma and judgement from peers for this choice. This study aimed to explore the attitudes that exist towards non-drinkers and examine what drives this stigma. Method Thematic analysis of four focus groups was undertaken, comprising 37 drinking and non-drinking Australian adults. Results Three themes were identified that elucidate the stigma, with non-drinkers being perceived as a: (1) threat to fun, a judgemental ‘sober eye’ disrupting the desired hedonistic environment created by alcohol, (2) threat to connection, described as difficult to initiate and maintain a social connection with and (3) threat to self, with the presence of a non-drinker described by drinkers as encouraging an unwanted reflection on the problematic aspects of their own drinking. Participant responses also suggested that the gender of the non-drinker influenced these perceptions. Conclusion Through the lens of Integrated Threat Theory, this study proposes that the stigma experienced by non-drinkers may be understood as a response to threats non-drinkers are perceived to pose to drinkers’ group values (e.g. hedonism) and self-esteem. This study offers new direction for health promotion efforts to challenge negative perceptions of non-drinkers

    Background: A major challenge in providing mental health interventions for young people is making such interventions accessible and appealing to those most in need. Online and app-based forms of therapy for mental health are burgeoning. It is therefore crucial to identify features that are most effective and engaging for young users. Objectives: This study reports a systematic review and meta-analysis of digital mental health interventions and their effectiveness in addressing anxiety and depression in young people to determine factors that relate to outcomes, adherence, and engagement with such interventions. Methods: A mixed methods approach was taken, including a meta-analysis of 9 randomized controlled trials that compared use of a digital intervention for depression in young people to a no-intervention control group, and 6 comparing the intervention to an active control condition. A thematic analysis and narrative synthesis of 41 studies was also performed. Results: The pooled effect size of digital mental health interventions on depression in comparison to a no-intervention control was small (Cohen’s d = 0.33, 95% CI 0.11 to 0.55), while the pooled effect size of studies comparing an intervention group to an active control showed no significant differences (Cohen’s d = 0.14, 95% CI -.04 to 0.31). Pooled effect sizes were higher when supervision was involved (studies with no-intervention controls: Cohen’s d = 0.52, 95% CI 0.23 to 0.80; studies with active control: Cohen’s d = 0.49, 95% CI -0.11, 1.01). Engagement and adherence rates were low. Qualitative analysis revealed that users liked interventions with a game-like feel and relatable, interactive content. Educational materials were perceived as boring, and users were put off by non-appealing interfaces and technical glitches. Conclusions: Digital interventions work better than no intervention to improve depression in young people when results of different studies are pooled together. However, these interventions may only be of clinical significance when use is highly supervised. Digital interventions do not work better than active alternatives regardless of the level of support. Future interventions need to move beyond the use of digital educational materials, considering other ways to attract and engage young people and to ensure relevance and appeal

    Detection of prokaryotic mRNA signifies microbial viability and promotes immunity

    Live vaccines have long been known to trigger far more vigorous immune responses than their killed counterparts. This has been attributed to the ability of live microorganisms to replicate and express specialized virulence factors that facilitate invasion and infection of their hosts. However, protective immunization can often be achieved with a single injection of live, but not dead, attenuated microorganisms stripped of their virulence factors. Pathogen-associated molecular patterns (PAMPs), which are detected by the immune system, are present in both live and killed vaccines, indicating that certain poorly characterized aspects of live microorganisms, not incorporated in dead vaccines, are particularly effective at inducing protective immunity. Here we show that the mammalian innate immune system can directly sense microbial viability through detection of a special class of viability-associated PAMPs (vita-PAMPs). We identify prokaryotic messenger RNA as a vita-PAMP present only in viable bacteria, the recognition of which elicits a unique innate response and a robust adaptive antibody response. Notably, the innate response evoked by viability and prokaryotic mRNA was thus far considered to be reserved for pathogenic bacteria, but we show that even non-pathogenic bacteria in sterile tissues can trigger similar responses, provided that they are alive. Thus, the immune system actively gauges the infectious risk by searching PAMPs for signatures of microbial life and thus infectivity. Detection of vita-PAMPs triggers a state of alert not warranted for dead bacteria. Vaccine formulations that incorporate vita-PAMPs could thus combine the superior protection of live vaccines with the safety of dead vaccines
