Regional differences in the reproductive parameters of the sparsely-spotted stingaree, Urolophus paucimaculatus, from South-Eastern Australia

Whether spatial variation occurs in the life-history traits of chondrichthyan species is important to fisheries modelling and assessments. A study on the reproductive parameters of Urolophus paucimaculatus from four separate regions across south-eastern Australia found regional differences in maximum total length (TL), size-at-maturity, size-at-maternity and litter sizes. Inshore embayments (Port Phillip Bay (PPB) and Corner Inlet (CI)) appear to allow for larger TLs (females and males) than do offshore areas (Lakes Entrance (LE) and Western Bass Strait (WBS)). Size-at-maturity and size-at-maternity decreased across longitude from west (PPB) to east (LE) and seasonality of parturition and ovulation occurred earlier in PPB (August-October) than in LE (September-December). Maximum litter size correlated with maximum TL (six in PPB, five in each of CI and LE, and four in WBS). There was uncertainty in classifying females for maternal condition because the reproductive cycle appears to range from a continuous annual cycle to a non-continuous biennial cycle. Much of the uncertainty arises from the ambiguity of observation of non-pregnant mature females, which have either aborted through capture and handling, or are in a 'resting year' between pregnancies. Most likely, the majority are reproducing annually with an unknown proportion of females non-continuous and resting between pregnancies.

An issues paper: the roots/routes of Australian architecture: elements of an alternative architectural history

The dynamism and mobility of architects in their approach to architecturaldesign practice provides a context that emphasises that architecture, likeculture, is not static or rooted in place, but is intricately configured throughthe dual processes of locality and mobility – both physical and theoretical. Theproduction of architecture in Australia, as in other immigrant-rich societies,provides a case for reinforcing the theory that architectural mobility and travelare integral to the architecture of place.This issues paper sets out to re-examine the contribution of geo-culturalinfluences upon Australia’s architectural lineage and considers a diverse rangeof themes across an equally broad timeframe; British colonial transpositions; thedissemination of Modernism in Australia; the latent contribution of mid-twentiethcentury European émigré architects; and the secreted history of Australia’sAsian architecture. Common to all, however, is the notion of architecturaltranslation as a process of influences transmitted, transposed or adapted toother contexts. It uses Australia as the focus from which to consider how globalcriticism, ideas and theories have travelled and continue to travel transverselyacross time and place, from the late-eighteenth century well into the twenty-first.This paper investigates translations through narratives, processes, networks andtraces of architectural manifestations and begins to draw lines of influence.

The Greek Diaspora of Melboure, Australia, through the eyes of the second generation Greek Australians

Melbourne has a large and dynamic Greek community that began to form in the 1950s with migration to Australia in the years following the Second World War and the Greek Civil War. The elders of this community, in particular, have tried to ensure that their culture and traditions are kept alive and are handed down from generation to generation. The long history and cultural richness of the Greek tradition is a great source of pride to its members, and this is a key characteristic of the Greek community of Australia. Young and old Greek Australians speak of their country of origin with great pride and passion, as it remains central to their perception of nationality and ethnicity. This importance placed on the retention of the language and culture of their nation of origin means that cultural transmission across generations is of great significance to the community and can provide valuable insight into their interpretation of their own experiences. This paper will present findings from a three generation study about health beliefs and practices of women in the Melbourne Greek community. The experience of granddaughters, who represent the second Australian generation, and how they see their grandmothers’ experience as migrants to Australia will be discussed. The impact of the Diaspora phenomenon and the creation of a Greek community in Melbourne will be considered in the context of health, memory, religion, Greek culture, food, and personal and group identity.

The Popular Education Network of Australia (PENA) and Twenty-First-Century critical education

Drawing on the philosophies and writings of Paulo Freire regarding education as activism, this paper will explore the history and activities of the Popular Education Network of Australia (PENA). The network, founded in 2009, involves educators, academics and community workers, working together on issues relating to critical pedagogy and social change in schools, communities and adult education contexts. Two symposia have been organised on critical education in Australia. In 2010, ‘Teaching and Learning for Social Justice and Action’ was the inaugural gathering. In 2012, ‘Freire Reloaded: Learning and Teaching to Change the World’ featured a diverse range of workshops and Professor Antonia Darder as keynote speaker and observer. Through the perspectives and experiences of five academics involved in PENA, this paper will explore the group’s activities and reflect on the inspiration drawn from the work of Freire, Darder and others. Creating spaces for discussion of critical pedagogy affords opportunities for academics, educators, teachers and activists to reflect on their practice and also leads to further spontaneous networking and planning of action. In this paper we argue that there is continuing importance, in fact urgency, in producing places and spaces for conscientisation to occur, and for examples of critical education to be shared amongst 21st century educators.

"I feel I can no longer endure": Families and the limits of Commitment in Australia, 1914-1919

Civilian endurance has again become a significant issue in understanding the nature of the First World War, especially since so much emphasis has returned to questions of consent and commitment in making and sustaining the conflict. Fundamental to that enquiry is an acknowledgement of the reality and legitimacy of the sentiments that drove individuals and communities to support the war. By extension, this also implies a need to understand the limits of that commitment, and of the capacity to endure the strains of war. This chapter probes civilian endurance through an examination of Australian families’ experiences of war and separation. It argues that persistent anxiety over loved ones at the front consumed individuals’ emotional resources and, even among the most patriotic Australians, tested commitment to the war.

Differing impact of a major biogeographic barrier on genetic structure in two large kangaroos from the monsoon tropics of Northern Australia

Tropical savannas cover 20-30% of the world's land surface and exhibit high levels of regional endemism, but the evolutionary histories of their biota remain poorly studied. The most extensive and unmodified tropical savannas occur in Northern Australia, and recent studies suggest this region supports high levels of previously undetected genetic diversity. To examine the importance of barriers to gene flow and the environmental history of Northern Australia in influencing patterns of diversity, we investigated the phylogeography of two closely related, large, vagile macropodid marsupials, the antilopine wallaroo (Macropus antilopinus; n = 78), and the common wallaroo (Macropus robustus; n = 21). Both species are widespread across the tropical savannas of Australia except across the Carpentarian Barrier (CB) where there is a break in the distribution of M. antilopinus. We determined sequence variation in the hypervariable Domain I of the mitochondrial DNA control region and genotyped individuals at 12 polymorphic microsatellite loci to assess the historical and contemporary influence of the CB on these species. Surprisingly, we detected only limited differentiation between the disjunct Northern Territory and QueenslandM. antilopinus populations. In contrast, the continuously distributedM. robustus was highly divergent across the CB. Although unexpected, these contrasting responses appear related to minor differences in species biology. Our results suggest that vicariance may not explain well the phylogeographic patterns in Australia's dynamic monsoonal environments. This is because Quaternary environmental changes in this region have been complex, and diverse individual species' biologies have resulted in less predictable and idiosyncratic responses.

Why do some species have geographically varying responses to fire history?

A capacity to predict the effects of fire on biota is critical for conservation in fire-prone regions as it assists managers to anticipate the outcomes of different approaches to fire management. The task is complicated because species' responses to fire can vary geographically. This poses challenges, both for conceptual understanding of post-fire succession and fire management. We examine two hypotheses for why species may display geographically varying responses to fire. 1) Species' post-fire responses are driven by vegetation structure, but vegetation - fire relationships vary spatially (the 'dynamic vegetation' hypothesis). 2) Regional variation in ecological conditions leads species to select different post-fire ages as habitat (the 'dynamic habitat' hypothesis). Our case study uses data on lizards at 280 sites in a ~ 100 000 km2 region of south-eastern Australia. We compared the predictive capacity of models based on 1) habitat associations, with models based on 2) fire history and vegetation type, and 3) fire history alone, for four species of lizards. Habitat association models generally out-performed fire history models in terms of predictive capacity. For two species, habitat association models provided good discrimination capacity even though the species showed geographically varying post-fire responses. Our results support the dynamic vegetation hypothesis, that spatial variation in relationships between fire and vegetation structure results in regional variation in fauna-fire relationships. These observations explain how the widely recognised 'habitat accommodation' model of animal succession can be conceptually accurate yet predictively weak. © 2014 The Authors.

Population genetic structure of the Australian caddisfly Lectrides varians Mosely (Trichoptera: Leptoceridae) and the identification of cryptic species in south-eastern Australia

Lectrides varians (Mosely) is a large, ecologically-important, caddisfly found in perennial and intermittent streams throughout much of eastern Australia. We conducted a population genetic analysis to investigate the dispersal potential of L. varians, building on previous works that have assessed life-history traits associated with drought resistance. Genetic analyses of L. varians from the Grampians region of Victoria, based on mitochondrial DNA sequence data, revealed extensive gene flow and a lack of genetic structure across the sample range (ΦST = 0.04). This suggests that the species is a strong disperser and is likely to be resilient to increased drying and habitat fragmentation under climate change considering other known resistance traits. However, during this study, two divergent genotypes were identified, indicating a potential species complex. A comprehensive phylogenetic analysis of L. varians across its current range was subsequently performed, confirming the species is indeed paraphyletic, consisting of one lineage that is restricted to the Grampians National Park and the other being widespread throughout south-eastern Australia. Further analyses revealed consistent morphological differences between these lineages supporting the notion that L. varians is a species complex. We discuss the implications of these findings with regard to conservation and taxonomy of this important invertebrate group.

Hungry for change: the food banking industry in Australia

Purpose – Over the last 20 years, food banks in Australia have expanded nationwide and are a well-organised “industry” operating as a third tier of the emergency food relief system. The purpose of this paper is to overview the expansion and operation of food banks as an additional self-perpetuating “tier” in the response to hunger.

Design/methodology/approach – This paper draws on secondary data sourced from the internet; as well as information provided by Foodbank Australia and Food Bank South Australia (known as Food Bank SA) to outline the history, development and operation of food banks. Food banking is then critically analysed by examining the nature and framing of the social problems and policies that food banking seeks to address. This critique challenges the dominant intellectual paradigm that focuses on
solving problems; rather it questions how problem representation may imply certain understandings.

Findings – The issue of food banks is framed as one of food re-distribution and feeding hungry people; however, the paper argue that “the problem” underpinning the food bank industry is one of maintaining food system efficiency. Food banks continue as a neo-liberal mechanism to deflect query, debate and structural action on food poverty and hunger. Consequently their existence does little to ameliorate the problem of food poverty.

Practical implications – New approaches and partnerships with stakeholders remain key challenges for food banks to work more effectively to address food poverty.

Social implications – While the food bank industry remains the dominant solution to food poverty in Australia, debate will be deflected from the underlying structural causes of hunger.

Originality/value – This paper contributes to the limited academic literature and minimal critique of the food bank industry in Australia. It proposes that the rapid expansion of food banks is a salient marker of government and policy failure to address food poverty.

Migration and obesity : the experience of Iranian migrants in Australia

 This thesis provided valuable data to better understand how migration relates to obesity trends. The research expanded the concepts and models of the impact of migration and acculturation on obesity by testing them in a population of Iranian immigrants to Australia.

Museum exhibition practice: recent developments in Europe, Canada and Australia

'Permanent' museum exhibitions or galleries are usually planned for a life of seven to ten years, but not infrequently survive for thirty years or more. When change finally occurs, it addresses new approaches in ideology, disciplines, technology and fashion. This chapter surveys such shifts in transnational history and Aboriginal cultures presented in museums.

Jail up; crime down does not justify Australia becoming an incarceration nation

The imprisonment rate in Australia is at unprecedented high levels, both interms of actual prisoner numbers and the rate at which it is increasing. Forthe first time in recorded history the incarceration rate in Australia has morethan doubled in less than 25 years. Prison is the harshest form ofpunishment in our system of justice and imposes considerable hardship onoffenders. It also comes at a considerable financial cost to the community.Accordingly, the surge in prisoner numbers is a significant macro social,economic and legal development. The increase did not occur pursuant to anoverarching strategic plan and is an area that is under-researched. Theprison population increase has arisen as a result of a ‘tough on crime’approach that continues without any sign of abatement. The use ofimprisonment should only be increased if there is a demonstrable benefit tothe community. This article examines whether there is a sound rationalebehind the rising trend in prison numbers. The increasing incarceration ratehas coincided with a significant reduction in the crime rate. A causalconnection between the two events (increased prisoner numbers andreduced crime) could constitute a powerful argument in favour of the surgein prison numbers. However, an examination of the empirical data inAustralia fails to demonstrate even a tenable link between these events. Wealso conclude that at the theoretical level there is no rationale for theincreased use of imprisonment. If the imprisonment rate continues to rise,there is a risk of a prison and financial crisis similar to that currently beingexperienced in the United States, which has resulted in an extremecounter-reaction in the form of a retrospective reduction of some prison terms.
