- Description: James McKain Meek was a Victorian-era graphic artist, miniature calligrapher and colonial eccentric with polymathic interests, who fell into obscurity at the end of the nineteenth century. This research re-discovers, re-presents and re-evaluates his body of graphic art. A single lithograph by Meek held in the Art Gallery of Ballarat’s collection generated the research which uncovered a significant body of work in Australia and overseas. Inspired by this re-discovered oeuvre, an exhibition was curated to mark Meek’s bicentenary, returning him to public view. An illustrated companion catalogue, the first scholarly commentary on Meek’s oeuvre, presented a series of essays exploring Meek’s works and situating them in their Victorian context and within a longer tradition of prints. The exegesis, the final element of this project, reflects on the research design, addresses curatorial and related issues, and deepens the examination of Meek’s output. An analysis of key works informed by Word and Image Studies explores his trademark verbal and visual interplay. Valuable research outcomes discussed include the ongoing conservation of works, contextualisation of material held in collections around the world, Meek’s place in the larger narrative of Australian art history, and his legacy. This tri-partite PhD thesis is comprised of exhibition, catalogue and exegesis: these components are complementary and designed to be considered together. The catalogue addresses an educated lay readership and the exegesis is an overarching academic commentary. The exegesis extends and references the catalogue, and both are grounded in Meek’s works, in particular, key works displayed in the exhibition. This research contends that Meek’s work is singular and argues for his re-instatement in the Australian graphic arts canon. His highly individual style and the fact he is local (in his special links with Ballarat and his Trans-Tasman career), make him of particular interest in the Victorian and Australasian contexts.

- Description: The present study investigated the intergenerational transmission of problem gambling and the potential mediating role of parental psychopathology (problem drinking, drug use problems, and mental health issues). The study comprised 3953 participants (1938 males, 2015 females) recruited from a large-scale Australian community telephone survey of adults retrospectively reporting on parental problem gambling and psychopathology during their childhood. Overall, 4.0% [95%CI 3.0, 5.0] (n = 157) of participants reported paternal problem gambling and 1.7% [95%CI 1.0, 2.0] (n = 68) reported maternal problem gambling. Compared to their peers, participants reporting paternal problem gambling were 5.1 times more likely to be moderate risk gamblers and 10.7 times more likely to be problem gamblers. Participants reporting maternal problem gambling were 1.7 times more likely to be moderate risk gamblers and 10.6 times more likely to be problem gamblers. The results revealed that the relationships between paternal-and-participant and maternal-and-participant problem gambling were significant, but that only the relationship between paternal-and-participant problem gambling remained statistically significant after controlling for maternal problem gambling and sociodemographic factors. Paternal problem drinking and maternal drug use problems partially mediated the relationship between paternal-and-participant problem gambling, and fully mediated the relationship between maternal-and-participant problem gambling. In contrast, parental mental health issues failed to significantly mediate the transmission of gambling problems by either parent. When parental problem gambling was the mediator, there was full mediation of the effect between parental psychopathology and offspring problem gambling for fathers but not mothers. Overall, the study highlights the vulnerability of children from problem gambling households and suggests that it would be of value to target prevention and intervention efforts towards this cohort. © 2016 Elsevier Ltd. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Shane Thomas” is provided in this record**

- Description: Internalized homophobia has been linked to depression among gay men, lesbians, and bisexuals. Relatively little research has investigated the link between internalized homophobia and suicidal thoughts and behaviors. The current research investigated the interrelations among internalized homophobia, depressive symptoms, and suicidal ideation by testing additive, mediation, and moderation models. Self-identified Australian gay men (n = 360), lesbians (n = 444), and bisexual women (n = 114) completed the Internalized Homophobia Scale, the Center for Epidemiological Studies Depression Scale, and the suicide subscale of the General Health Questionnaire. Results supported the additive and partial mediation models for gay men and the mediation and moderation models for lesbians. None of the models were supported for bisexual women. The findings imply that clinicians should focus on reducing internalized homophobia and depressive symptoms among gay men and lesbians, and depressive symptoms among bisexual women, to reduce suicidal ideation. © 2016 Taylor & Francis.

The life and times of Dr Hermann Beckler (1828-1914) : An Australian - Barvarian Odyssey

- Description: The principal aim of this research thesis has been to reconstruct the life and times of Dr Hermann Beckler (1828-1914), a Bavarian-born scientist and adventurer who spent six years in Australia between 1856 and 1862. This study constitutes the first authoritative analysis of Beckler’s life. It focuses on the various turning points that influenced his odyssey-like journey from Bavaria to Australia and back again, as well as his travels within Australia, his interest in the natural environment and the botany of Australia, and his empathy towards the Indigenous people. Beckler was a product of the Age of Romanticism. He was an enigmatic and contemplative person, yet possessed a degree of toughness and resilience to overcome what appeared to be initially a self-imposed exile, replete with self-recriminations, as he tried to establish himself, firstly as a medical doctor and then as a pharmacist in the pioneering Moreton Bay region of colonial New South Wales. His interests in the natural sciences provided a solution to the problem of employment, and his botanical collecting skills ultimately gained him a position with Dr Ferdinand Mueller of the Melbourne Botanic Gardens. He worked as a botanical plant collector in northern New South Wales before his medical qualifications and botanical saw him appointed as medical doctor and botanist to the Victorian Exploring Expedition 1860-1861 led by Robert O’Hara Burke and William John Wills. Beckler recognized this appointment as an opportunity to explore the hitherto unknown parts of the interior of Australia and while he did his best to fulfill his role, he was frustrated by the mismanagement of the whole expedition by Burke’s erratic leadership and by the ineptitude of the Royal Society of Victoria’s Exploration Committee. He remains one of Australia’s and Germany’s forgotten explorer botanists. This thesis aims to bring to life Beckler’s contribution to this important episode in Australian colonial history.

- Description: Technical challenges in using diatoms for paleolimnological work are the identification and enumeration of diatom valves. Variations exist in the minimum number of valves to identify, ranging from 100 to 700 valves of the dominant species. This task can be very time consuming, particularly when the diatom valves are not abundant. This research was conducted to determine the minimum number of valves to be identified in the diatom assemblages from Rawapening Lake, Central Java, Indonesia. Based on the 314 samples obtained from Rawapening Lake, the diatom efficiency rose above 0.85 upon the minimum count of 300 valves. The number of diatom species identified remained stable after the minimum of 300 valves. Therefore, the minimum number of diatom's valves identified to represent the assemblage for paleolimnological analysis was 300.

In this paper, we provide a perspective that might be helpful to explain the success of this scam. In a similar way to the "The Nigerian letter", we propose that the scam techniques appeal to strong emotions, which are clearly involved in Romantic relationships. We also assume that the same success factors found in normal relationships contribute to the success of the romance scam. In an exploratory study using a qualitative analysis of fraudulent profiles from an international dating website, we examined this assumption. The findings show that personal affinities related to personal romantic imaginations, which are described by personal love stories, play an important role in the success of a romance scam. © 2016 International Journal of Cyber Criminology (IJCC).

- Description: This study examined various psychometric properties of the items comprising the shame and guilt scales of the Test of Self-Conscious Affect-Adolescent (TOSCA-A) in a group children between 8 and 11 years of age. A total of 699 children (367 females and 332 males) completed these scales, and also measures of depression and empathy. Confirmatory factor analysis (CFA) provided support for an oblique two-factor model, with the originally proposed shame and guilt items comprising shame and guilt factors, respectively. There was good internal consistency reliability for the shame and guilt scales, with omega coefficient values of 0.77 and 0.81 for shame and guilt, respectively. Also, shame correlated with depression symptoms positively (0.34, p < 0.001) and had no relation with empathy (-0.07, ns). Guilt correlated with depression symptoms negatively (-0.28, p < 0.001), and with empathy positively (0.13. p < 0.05). Thus there was support for the convergent and discriminant validity of the shame and guilt factors. Multiple-group CFA comparing this group of children with a separate group of adolescents (320 females and 242 males), based on the chi-square difference test, supported full metric invariance, the intercept invariance of 17 of the 30 shame and guilt items, and higher latent mean scores among children for both shame and guilt. The non-equivalency for intercepts and mean scores were of small effect sizes. Comparisons based on the difference in root mean squared error of approximation values supported full measurement invariance and no group difference for latent mean scores. The findings in the current study support the use of the TOSCA-A in children and the valid comparison of scores between children and adolescents, thereby opening up the possibility of evaluating change in the TOSCA-A shame and guilt factors over these developmental age groups. © 2016 Watson, Gomez and Gullone.

The use of on-farm water points and artificial wildlife ponds in providing habitat for fauna in the Wimmera and Southern Mallee, Victoria, Australia
- Authors: Starks, Jonathan

- Description: Fauna living in arid environments face strong ecological and physiological constraints. Water is the key requirement and vertebrates exhibit a range of adaptations for survival. Some species obtain water from their diet, but those which require water to drink or as habitat must either live in or near permanent water, or move in search of water. This strongly influences the distribution and abundance of vertebrate species in arid environments. In arid agricultural landscapes, the development of artificial water sources for stock has benefited water-dependant native fauna, particularly frogs. Little is known about the effects of removal of artificial water sources in these environments. In North-western Victoria, completion of the Northern Mallee Pipeline and the proposed construction of the Wimmera Mallee Pipeline will ultimately replace over 20,000 farm dams, resulting in the widespread loss of an open water resource currently used by fauna across the Wimmera and southern Mallee. The wildlife values of the different on-farm water points in the Northern Mallee Pipeline region and the remaining Wimmera Mallee Domestic and Stock Channel System were examined. Species richness and abundance of vertebrates were surveyed at farm dams, channels and stock troughs in open paddocks, and at farm dams in Mallee woodlands. Mallee woodlands with no available water were also surveyed. Sites were surveyed once per season to determine which species were utilising the different on-farm water points and Mallee woodlands. Knowledge of their usage by different species allowed the importance of each water point type to be determined and the impact of the closure of the channel system to be assessed. The study recorded 57 vertebrate species in the Northern Mallee Pipeline region, including six reptile, 43 bird, seven mammal and zero frog species. Surveys in the Wimmera Mallee Channel/dam region recorded 74 different species, including three reptile , 57 bird, eight mammal and six frog species. Overall species richness and abundance was highest at sites with a farm dam in a Mallee woodland, and the levels of species richness and abundance were significantly higher than at sites with Mallee woodland and no available water. The differences between the two site types were due mainly to greater abundance of water- dependant species at farm dams in Mallee woodland sites. For water points in open paddocks, species richness and abundance was highest at sites with a farm dam in an open paddock and lowest at sites with a stock trough in an open paddock. The difference between the different open paddock water point types were significant, and like woodland sites, were driven by greater numbers of water-dependant species. The study also examined whether purpose-built artificial wildlife ponds could provide habitat for water-dependant fauna and whether artificial wildlife ponds could potentially maintain fauna populations after de-commissioning of the existing channel system. The results of this study showed that artificial wildlife ponds placed in Mallee woodlands can provide habitat for birds, both in the Northern Mallee Pipeline region and the Wimmera Mallee Channel/dam region. The results also showed that these wildlife ponds can support species assemblages at levels comparable to a farm dam in a Mallee woodland, demonstrating that wildlife ponds can be effective in providing a degree of ‘replacement’ habitat for birds on farms. Frogs were not recorded using wildlife ponds situated in Mallee woodlands and this was considered due to the wildlife ponds being placed at least 900 metres from a nearby water source potentially too far for many frog species to disperse in an arid environment. Given these findings, the position of ponds was adjusted for the ponds installed in Black Box woodlands. Wildlife ponds in Black Box woodlands were also successful in providing habitat for birds and functioned as an important source of water for water-dependant birds in summer. Frogs were recorded using the wildlife ponds situated in Black Box woodlands and this was most likely due to their close proximity (<200 metres) to a nearby water source, as well as being located in a wetland-associated vegetation type. The success of the wildlife ponds concept has been demonstrated both in their ability to function as habitat for water-dependant fauna and through widespread community acceptance and support. With the de-commissioning of the channel and dam system removing open water sources from the farming landscape, artificial wildlife ponds installed on farms across the region could provide not just a vital habitat resource supporting water-dependant fauna, but in many areas, the only source of water for wildlife within the Wimmera and southern Mallee regions.

- Description: Fauna living in arid environments face strong ecological and physiological constraints. Water is the key requirement and vertebrates exhibit a range of adaptations for survival. Some species obtain water from their diet, but those which require water to drink or as habitat must either live in or near permanent water, or move in search of water. This strongly influences the distribution and abundance of vertebrate species in arid environments. In arid agricultural landscapes, the development of artificial water sources for stock has benefited water-dependant native fauna, particularly frogs. Little is known about the effects of removal of artificial water sources in these environments. In North-western Victoria, completion of the Northern Mallee Pipeline and the proposed construction of the Wimmera Mallee Pipeline will ultimately replace over 20,000 farm dams, resulting in the widespread loss of an open water resource currently used by fauna across the Wimmera and southern Mallee. The wildlife values of the different on-farm water points in the Northern Mallee Pipeline region and the remaining Wimmera Mallee Domestic and Stock Channel System were examined. Species richness and abundance of vertebrates were surveyed at farm dams, channels and stock troughs in open paddocks, and at farm dams in Mallee woodlands. Mallee woodlands with no available water were also surveyed. Sites were surveyed once per season to determine which species were utilising the different on-farm water points and Mallee woodlands. Knowledge of their usage by different species allowed the importance of each water point type to be determined and the impact of the closure of the channel system to be assessed. The study recorded 57 vertebrate species in the Northern Mallee Pipeline region, including six reptile, 43 bird, seven mammal and zero frog species. Surveys in the Wimmera Mallee Channel/dam region recorded 74 different species, including three reptile , 57 bird, eight mammal and six frog species. Overall species richness and abundance was highest at sites with a farm dam in a Mallee woodland, and the levels of species richness and abundance were significantly higher than at sites with Mallee woodland and no available water. The differences between the two site types were due mainly to greater abundance of water- dependant species at farm dams in Mallee woodland sites. For water points in open paddocks, species richness and abundance was highest at sites with a farm dam in an open paddock and lowest at sites with a stock trough in an open paddock. The difference between the different open paddock water point types were significant, and like woodland sites, were driven by greater numbers of water-dependant species. The study also examined whether purpose-built artificial wildlife ponds could provide habitat for water-dependant fauna and whether artificial wildlife ponds could potentially maintain fauna populations after de-commissioning of the existing channel system. The results of this study showed that artificial wildlife ponds placed in Mallee woodlands can provide habitat for birds, both in the Northern Mallee Pipeline region and the Wimmera Mallee Channel/dam region. The results also showed that these wildlife ponds can support species assemblages at levels comparable to a farm dam in a Mallee woodland, demonstrating that wildlife ponds can be effective in providing a degree of ‘replacement’ habitat for birds on farms. Frogs were not recorded using wildlife ponds situated in Mallee woodlands and this was considered due to the wildlife ponds being placed at least 900 metres from a nearby water source potentially too far for many frog species to disperse in an arid environment. Given these findings, the position of ponds was adjusted for the ponds installed in Black Box woodlands. Wildlife ponds in Black Box woodlands were also successful in providing habitat for birds and functioned as an important source of water for water-dependant birds in summer. Frogs were recorded using the wildlife ponds situated in Black Box woodlands and this was most likely due to their close proximity (<200 metres) to a nearby water source, as well as being located in a wetland-associated vegetation type. The success of the wildlife ponds concept has been demonstrated both in their ability to function as habitat for water-dependant fauna and through widespread community acceptance and support. With the de-commissioning of the channel and dam system removing open water sources from the farming landscape, artificial wildlife ponds installed on farms across the region could provide not just a vital habitat resource supporting water-dependant fauna, but in many areas, the only source of water for wildlife within the Wimmera and southern Mallee regions.

- Description: Studies in the literature describe the ability of dietary supplementation by omega-3 fish oil to increase the pumping efficiency of the left ventricle. Here we attempt to reconcile such studies with our own null results. We undertake a quantitative analysis of the improvement that could be expected theoretically, subject to physiological constraints, by posing the following question: By how much could efficiency be expected to increase if inefficiencies could be eliminated? Our approach utilizes thermodynamic analyses to investigate the contributions, both singly and collectively, of the major components of cardiac energetics to total cardiac efficiency. We conclude that it is unlikely that fish oils could achieve the required diminution of inefficiencies without greatly compromising cardiac performance.

- Description: Objectives: The field of sport injury prevention has seen a marked increase in published research in recent years, with concomitant proliferation of lay sport safety resources, such as policies, fact sheets and posters. The aim of this study was to catalogue and categorise the number, type and topic focus of sport safety resources from a representative set of key organisations. Design: Cataloguing and qualitative document analysis of resources available from the websites of six stakeholder organisations in Australia. Setting: This study was part of a larger investigation, the National Guidance for Australian Football Partnerships and Safety (NoGAPS) project. Participants: The NoGAPS study provided the context for a purposive sampling of six organisations involved in the promotion of safety in Australian football. These partners are recognised as being highly representative of organisations at national and state level that reflect similarly in their goals around sport safety promotion in Australia. Results: The catalogue comprised 284 resources. More of the practical and less prescriptive types of resources, such as fact sheets, than formal policies were found. Resources for the prevention of physical injuries were the predominant sport safety issue addressed, with risk management, environmental issues and social behaviours comprising other categories. Duplication of resources for specific safety issues, within and across organisations, was found. Conclusions: People working within sport settings have access to a proliferation of resources, which creates a potential rivalry for sourcing of injury prevention information. Important issues that are likely to influence the uptake of safety advice by the general sporting public include the sheer number of resources available, and the overlap and duplication of resources addressing the same issues. The existence of a large number of resources from reputable organisations does not mean that they are necessarily evidence based, fully up to date or even effective in supporting sport safety behaviour change. © 2016, BMJ Publishing Group.

- Description: If, as according to Robin (2015: online), “islands are idealised ecological worlds, the Edens of a fallen planet’”, the rationale underpinning tourism expansion should acknowledge MacLeod’s (2013) notion of “cultural realignment” that calls for optimal and resilient encounters. This introductory article to the subsequent theme section of the journal on sustainable tourism acts as a bridge toward the development of emergent themes that describe how island peoples adapt and respond in localised cultural islandscapes as a consequence of tourism expansion. The links between cultural alignment and social-ecological resilience are clear and the principal and overarching question posed in this introductory article is: To what extent are islandscapes resilient to rapidly changing utilities, significances and ways of life wrought by tourism expansion? The vulnerabilityresilience duality remains firmly entrenched in the discourse on islands where tourism has become prominent, and although tourism provides some resiliency, overall, islandscapes remain subject to externally driven fast and slow change that exercises an overwhelming influence. Islander agency will likely remain subject to the fluctuations in the demands of the tourism supply chain. Therefore, tourism as a standalone focus of islands is a high-risk proposition, especially in contexts where externally driven change is likely to intensify.

- Description: This thesis investigates tourism governance models for sustainable heritage tourism in Kandy, a world heritage city situated in central Sri Lanka. Additionally, it explains how the success of sustainable heritage tourism has underpinned sustainable livelihoods development from a socio-cultural perspective. The main objective is to find, identify and assess the influence of tourism governance on sustainable heritage tourism in Sri Lanka. Stemming from this approach is the development of a tourism governance model for sustainable heritage tourism in Kandy. This thesis is intended as a response to the challenges of adopting a sustainable livelihoods development approach. Accordingly, it investigates the role sustainable heritage tourism plays in host community development within the context of sociocultural, economic and environmental aspects in Kandy. Employing a qualitative methodological approach, this thesis is underpinned by an interpretive research philosophy. Research data was collected through field-based in-country interviews and open-ended questionnaires as this approach allowed respondents to offer more information and to include their feelings, attitudes and understanding of the subject. Research results from in-country fieldwork reveal that tourism governance models have a major influence on the viability of sustainable heritage tourism at Sri Lankan heritage destinations. Macro-scale and micro-scale factors were found to be influential in tourism governance models. Additionally, sustainable heritage tourism was found to be a persuasive factor in host community development. Research from this thesis provides policy recommendations and potential management frameworks for tourism practitioners and policy makers. These insights into Kandy and other Sri Lankan heritage localities enable improvement of tourism governance systems and sustainable heritage tourism.

- Description: It is widely acknowledged that learning and development (L&D) is key to well-being, innovation andsuccess for individuals, organizations and societies (Delahaye, 2011). Learning and development practice involves application of distinctive knowledge, skills and techniques in distinctive contexts. The sheer range of contexts and kinds of expertise associated with this work produces a complex challenge to any attempt to model L&D practice. The Australian Institute of Training and Development (AITD) took up this challenge in the Australian setting. A team of researchers was engaged to produce a model of L&D practice that the organization could use to conceptualize the work of its members and refine organizational strategy in areas such as professional development services. Although there have been attempts to represent the work of L&D practitioners (e.g. the ASTD ‘Competency Model’), the research presented here focused on the Australian setting and was also guided by a commitment to recognizing the role of organizational contexts in shaping L&D practice. This focus on context distinguishes the model from others that are concerned with the expertise and attributes of individual L&D practitioners. The model presented here thus represents contexts of L&D practice as well as knowledge and skills applied within them. The article describes the research process used to develop the model, including analysis of existing models, interviews with senior L&D practitioners and a survey of practitioners. The result is a model that acknowledges the complexity of L&D practice in a contemporary environment.

- Description: We give a formula for the subdifferential of the sum of two convex functions where one of them is the supremum of an arbitrary family of convex functions. This is carried out under a weak assumption expressing a natural relationship between the lower semicontinuous envelopes of the data functions in the domain of the sum function. We also provide a new rule for the subdifferential of the sum of two convex functions, which uses a strategy of augmenting the involved functions. The main feature of our analysis is that no continuity-type condition is required. Our approach allows us to unify, recover, and extend different results in the recent literature.

- Description: This chapter discusses the importance of flue-gas treatment and the effect of its impurities on post-combustion CO2 capture (PCC) process performance. Important consequences of nonoptimized flue-gas treatment include atmospheric emissions, amine degradation, extra maintenance requirements through corrosion or fly ash deposition, and waste handling. Each of these areas is strongly dependent on the others. We briefly describe existing flue-gas separation technologies and compare them to the requirements of PCC. Further pretreatment technologies are suggested to improve the composition and thereby the properties of the flue gas entering the PCC plant. For optimal plant operation, the overall process from boiler to atmosphere and waste needs to be analyzed holistically, because: certain approaches can increase efficiency when treating multiple contaminants compared with treating each component separately;most "cleaning" steps influence or generate other compounds that could reduce the performance of the process chain;all costs associated with the treatment chain increase production costs, with little or no increase in value. © 2016 Copyright © 2016 Elsevier Ltd All rights reserved.

- Description: Background: Body dissatisfaction is associated with a range of adverse outcomes, including impaired psychological health, low physical activity and disordered eating. This longitudinal study used the Factors Influencing Transitions in Girls' Active Leisure and Sport (FITGALS) dataset to examine trends in body image of adolescent females. Specifically, the study examined satisfaction with body size, physical appearance and dieting behaviour for two cohorts at transitional life phases in two geographic regions longitudinally over a 3-year period. Methods: A sample of 732 adolescent females in Grade 7 (n = 489, 66.8 %) and Grade 11 (n = 243, 33.2 %) at randomly selected Australian metropolitan and non-metropolitan secondary schools responded to a questionnaire in three successive years from 2008 to 2010. Participants reported perceptions about their body size and physical appearance and whether they were, or ought to be, on a diet. The data were analysed using a series of longitudinal logistic regression models. Results: Dieting and dissatisfaction with body size significantly increased over time and more so for older than younger girls. Region significantly moderated the effect of grade level regarding dissatisfaction with body size but not dieting. In non-metropolitan regions, those in the younger cohort were significantly more likely to be dissatisfied with their body size than the older cohort; whereas in metropolitan regions, those in the older cohort were significantly more likely to be dissatisfied with their body size than the younger cohort. Adolescent female's perceptions of their appearance were unchanged over time, region and grade level. Conclusions: Differences across time, region and grade level were found among adolescent females on body size and dieting behaviour, but not physical appearance. Adolescent females experience early and increasing body size dissatisfaction and dieting as they age, but stable perceptions of physical appearance. Age and geographic region are important considerations for the timing and targeting of interventions to address body image concerns. Further investigation of regional differences in body image perceptions and factors that affect these is warranted. The findings of this study highlight the ongoing need for strategies during adolescence to promote a healthy appreciation of body size and appearance. © 2016 The Author(s).
