Responses to Australian society and culture by Greek-Australian writers

Focuses on the themes and preoccupations in Greek-Australian literature that reflect the influence of Australia on the traditional sense of identity of Greek migrants. Predominant concerns connected with identity are those of nostalgic references to the homeland, feelings of alienation and discrimination. These themes are related to what is recognised in life and in literature as "xenitia". Second generation writers reveal an acceptance of belonging to two cultures and having dual identities.

Lithium toxicity in yeast is due to the inhibition of RNA processing enzymes

Hal2p is an enzyme that converts pAp (adenosine 3',5' bisphosphate), a product of sulfate assimilation, into 5' AMP and Pi. Overexpression of Hal2p confers lithium resistance in yeast, and its activity is inhibited by submillimolar amounts of Li+in vitro. Here we report that pAp accumulation in HAL2 mutants inhibits the 5'3' exoribonucleases Xrn1p and Rat1p. Li+ treatment of a wild-type yeast strain also inhibits the exonucleases, as a result of pAp accumulation due to inhibition of Hal2p; 5' processing of the 5.8S rRNA and snoRNAs, degradation of pre-rRNA spacer fragments and mRNA turnover are inhibited. Lithium also inhibits the activity of RNase MRP by a mechanism which is not mediated by pAp. A mutation in the RNase MRP RNA confers Li+ hypersensitivity and is synthetically lethal with mutations in either HAL2 or XRN1. We propose that Li+ toxicity in yeast is due to synthetic lethality evoked between Xrn1p and RNase MRP. Similar mechanisms may contribute to the effects of Li+ on development and in human neurobiology.

The in situ physiology of "Nostocoida limicola" II, a filamentous bacterial morphotype in bulking activated sludge, using fluorescence in situ hybridization and microautoradiography

The in situ physiology of the actinobacterial bulking and foaming filamentous bacterium "Nostocoida limicola" II was studied by fluorescence in situ hybridization/microautoradiography. Substrate assimilation patterns of pure cultures of this bacterium were different to those seen in activated sludge biomass samples. There was no evidence to suggest that "N. limicola" II preferred hydrophobic substrates, but evidence was produced to support the view that it is metabolically active under anaerobic conditions in activated sludge.

Challenges in conserving indigenous culture in Minahasa : culture, Genius Loci and the Indonesian Environmental Planning system

Culture and spirit of land is integral to Indigenous community meaning and identity. With colonisation, transmigration and assimilation policies and practices over the last 200 years, many Indigenous communities, like the Minahasa, have witnessed their culture, curatorial responsibilities, and their mythological associations to their lands eroded. Minahasa, meaning 'becoming one united', encompasses some eight ethnic communities who reside in the Minahasa regencies in the North Sulawesi Province on Sulawesi Island in Indonesia. The region was first colonised by the Portuguese in the 16th century, and then by the Dutch VOC (Verenigde Oostindische Compagnie) in the 17th and 18th centuries bringing a strong Christian Protestant faith to the communities that appropriated many of the cultural symbols and mythological narratives of the Minahasa, and now compromises the largest concentration of Christian faith in the Indonesian archipelago being one of the reasons why there was considerable political requests for the region to formally become a province of The Netherlands in the lead up to Indonesian independence in 1945.

North Sulawesi never developed any large empire like on other islands in the archipelago. In 670, the leaders of the different tribes, who all spoke different languages, met by a stone known as Watu Pinawetengan. There they founded a community of independent states, who would form one unit and stay together and would fight any outside enemies if they were attacked, and the Dutch used this cultural ethos to help unite the linguistically diverse Minahasa confederacy under their colonial regime. Integral to the Minahasa is the Watu Pinawetengan and the series of narratives that enjoin the Minahasan communities to this place and around Lake Tondano. With Indonesian governance considerable angst has been launched by the Minahasa about loss of local autonomy, generic Indonesian policies, and a lack of respect of Indigenous culture and non-mainstream religions within this predominantly Moslem nation. This paper reviews the state of knowledge as to the cultural associations and genius loci meanings of the Minahasa, to their landscape and place, cast against contemporary Indonesian 10 year plans and policies that seek to generically manage the collective Indonesian archipelago as one community and landscape. It is a critique about the Minahasan Indigenous land use and planning philosophies, against top-down generic land use and environmental policies and plans written in Jakarta for generic application across the Indonesian archipelago.

Enabling innovation in information technology outsourcing : an empirical study

Information technology outsourcing has become a pervasive and important phenomenon in business organizations and there is substantial evidence about its benefits and pitfalls. Initially, firms used outsourcing as a way to lower costs, gain access to expertise and focus on core activities. Recently, there is a shift in focus and more firms are outsourcing to attain innovative products and services. However, current research is still unclear about how innovation can be achieved through outsourcing. Drawing predominantly from the dynamic capability theory, the objective of this paper is to explore how absorptive capacity unfolds as a process within and between firms when client firms outsource their information technology services with expectations of innovation generation. In this paper, we propose a research model that links absorptive capacity to innovation generation. We draw on three case studies to focus on how absorptive capacity, as a process, impacts innovation generation. Results show that assimilation and transformation stages are critical in generating radical innovation while acquisition and exploitation play a key role in incremental innovation. The implications of these findings for both researchers and practitioners are discussed.

Performing the 1950s New Australian

As a tentative beginning to locating a particularly local Australian brand of a post-colonial materialist (formalist) cinema this paper contextualises the recycling and re-samplings of mainstream industrial cinema that I have recently undertaken. I aim to place this practice within emerging discourses of hybridity, crossing-borders and a Global Cinema. This research speaks to my earliest experiences of migration into Australia, of becoming Australian, unfolding in my 50s childhood and enunciates the pressures my parents’ migration placed on them. The focus of this work articulates the somewhat emptied and gutted voice of the New Australian, a 50s term for the assimilated migrant (CAB 1948) of which the Dutch were considered exemplar performers, good white New Australians, who neatly left their Dutch identity at the door but who never-the-less witnessed the ambiguities of the ideologies they implicitly embraced.

Minahasan indigenous perspectives on place planning and management : tracing the indigenous culture through the lens of local wisdom

Indigenous cultures draw upon many thousands of years of residency and environmental adaptation offering unique knowledge resources to better understand our landscapes and environment. The Minahasan society, on the island of Sulawesi in the Indonesian archipelago, is one such Indigenous community. The Minahasan are the Indigenous community of northern Sulawesi, before the Portuguese and Dutch 1500-1900 colonization of this island, and the later nationalist cultural assimilation following post Indonesian independence. Thus, some 500 years of post-European contact and management can be contrasted against over I 00,000 years of Minahasan society. Further, the majority of this colonisation has been focused upon the coastal fringes resulting in a relatively intact Minahasan cultural landscape within the interior of northern Sulawesi focused upon the Tondano Lake catchment. This paper considers the importance of the Minahasan-formed cultural landscape, its importance to this culture, and the role and influence it continues to have in settlement formation and planning in northern Sulawesi despite conventional Indonesian and Western-informed sustainable urban and regional planning traditions and knowledge. It draws upon intensive qualitative research using 14 different villages, to analyse and compare local knowledge and land-relationships developed by the respective communities to manage and curate their unique characteristics as well as ensuring adaption without compromising their cultural, social and economic values. The research embodies this ethnoecological information in seeking to analyse historical and contemporary land use planning systems, and to offer a future planning perspective that will respect and endure this relationship and environmental management regime.

Sexual abuse in 'Disgrace' and 'Cereus Blooms at Night': the case for hope

Abuse is rife in Disgrace by J.M. Coetzee and Cereus Blooms at Night by Shani Mootoo. Sexual violence is in both narratives, part of their richly textured social, emotional and political worlds. Fiction involving various traumas seems bleak, almost hopeless, perhaps weighted by sadness. Yet both these novels, even through depictions of rupturing, disruptive rape, trigger a recognition of possibility and potential among characters and perhaps readers. It is in this open ended potential for betterment of some kind that hope lies. What is the nature of hope and to what extent is it present in these novels? In this paper, I explore the emotion of hope in relation to the notion of becoming as elaborated on by Gilles Deleuze and Felix Guattari particularly in A Thousand Plateaus. They expound on Remy Chauvin‟s term “aparallel evolution” in relation to becoming (Deleuze and Guattari, 11). Deleuze also states that becoming is not a “phenomena of imitation or assimilation”. Rather, it is an encounter, “a double capture” (Deleuze and Parnet 2) between heterogeneous elements. There is no end or destination in becoming; it is constant change. I examine the transformative potential of becoming to elicit signs of hope in these novels. David Lurie, the self-absorbed womaniser and arguably rapist, becomes-dog by the end of Disgrace. How does this contribute to any sense of redemption and consequently hope? And how does hope emanate from the beaten, broken, brutally raped Mala Ramchandin in Cereus Blooms at Night? At heart, this paper is an acknowledgment of the unique relation literature has with life and the enriching insight that it may provide into the expression of hope.

Mobile devices in social contexts

The development of mobile devices has occurred with unprecedented pace since the late nineties, and the increase of generic services has proliferated in most developed countries, driven by the expanding technological capabilities and performance of mobile platforms. This dissertation investigates how consumer objectives, orientation and behavior can aid in explaining the adoption and use of a new type of mobile devices: "app phones". This dissertation focuses its effort on two focal influences of adoption and use; social influences and competing forces. Through a qualitative case study and field study this dissertation explores early adoption and use of iPhones. The case study is a one-shot cross-sectional case study that investigates five individuals, related through the same social network, and their decision to adopt an iPhone prior to its release in Denmark. This adoption decision engenders high switching costs as adopters lack references to imitate and need skills to unlock and jailbreak their iPhones to make them work on Danish networks. The specific purpose of the case study is to explore how social influences impact mobile users' early adoption decisions, as it is well known in the literature that people with similar characteristics, tastes, and beliefs often associate in the same social networks and, hence, influence each other. The field study is cross-sectional with multiple snapshots and explores fifteen individuals part of the same university study, who recieves an iPhone for a period of seven months short after its release in Denmark. The specific purpose of the field study is to explore how competing forces of iPhone usage influence assimilation, i.e. the degree to which the iPhone is used, over time. The dissertation is reported through four articles and is directed at both academic researchers and practitioners. The study emphasizes the importance of social influences and competing forces in the investigation of adoption and use of certain mobile devices.

Changes in the nutritional composition of captive early-mid stage Panulirus ornatus phyllosoma over ecdysis and larval development

Elucidation of the key nutritional requirements for complete larval development of the tropical spiny rock lobster, Panulirus ornatus, presents a major challenge for the development of robust commercial aquaculture for this crustacean. As a foundation study in this area, the chemical composition of early-mid stage P. ornatus phyllosoma (Stages I-VI) receiving a novel formulated diet was analysed immediately prior and post-ecdysis to provide insight into the crude nutritional trends during the larval development cycle. From the onset of moulting, cyclical patterns were evident in the proximate composition of phyllosoma, resulting in substantial restructuring between the pre- and post-moult stages of the moult cycle. Proportions of protein, lipid and ash were high at the premoult stage, reflecting growth and nutrient accumulation over the intermoult period, and reduced at the post-moult stage, reflecting the large uptake of water to facilitate subsequent growth. Polar lipid was the dominant lipid class, accounting for >. 90% of the total lipid content. Conversely, triacylglycerol concentrations were low (<. 5%), despite being the principal lipid class available in the formulated diet. Likewise, despite receiving high concentrations of eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3) (9.2 and 7.6% of the dietary lipid source, respectively), levels of these fatty acids were comparatively low in phyllosoma (3.4 and 4.7%, respectively). In contrast, there is selective deposition of these fatty acids in wild caught phyllosoma. This finding suggests a poor assimilation of triacylglycerols by captive larvae and highlights the importance of future investigations into alternative sources of EPA and DHA. Ultimately, this study provides insight into the nutritional requirements of phyllosoma, providing valuable knowledge on diet formulation for commercially viable hatchery production of spiny rock lobsters. © 2014 Elsevier B.V.

Tracking spatial distribution of human-derived wastewater from Davis Station, East Antarctica, using δ15N and δ13C stable isotopes.

Stable isotope ratios, δ15N and δ13C were effectively used to determine the geographical dispersion of human derived sewage from Davis Station, East Antarctica, using Antarctic rock cod (Trematomus bernacchii). Fish within 0-4km downstream of the outfall exhibited higher δ15N and δ13C values relative to reference sites. Nitrogen in particular showed a stepped decrease in δ15N with increasing distance from the discharge point by 1-2‰. Stable isotopes were better able to detect the extent of wastewater contamination than other techniques including faecal coliform and sterol measures. Uptake and assimilation of δ15N and δ13C up to 4km from the outfall adds to growing evidence indicating the current level of wastewater treatment at Davis Station is not sufficient to avoid impact to the surrounding environment. Isotopic assimilation in T. bernacchii is a viable biomarker for investigation of initial sewage exposure and longer term monitoring in the future.

Quantifying and modelling the carbon sequestration capacity of seagrass meadows-a critical assessment

Seagrasses are among the planet's most effective natural ecosystems for sequestering (capturing and storing) carbon (C); but if degraded, they could leak stored C into the atmosphere and accelerate global warming. Quantifying and modelling the C sequestration capacity is therefore critical for successfully managing seagrass ecosystems to maintain their substantial abatement potential. At present, there is no mechanism to support carbon financing linked to seagrass. For seagrasses to be recognised by the IPCC and the voluntary C market, standard stock assessment methodologies and inventories of seagrass C stocks are required. Developing accurate C budgets for seagrass meadows is indeed complex; we discuss these complexities, and, in addition, we review techniques and methodologies that will aid development of C budgets. We also consider a simple process-based data assimilation model for predicting how seagrasses will respond to future change, accompanied by a practical list of research priorities.

Benefits of education at the intensive margin: childhood academic performance and adult outcomes among American immigrants

Using the Children of the Immigrants Longitudinal Study (CILS), we examine the associationbetween education at the intensive margin and twenty pecuniary and non-pecuniary adultoutcomes among first- and second-generation American immigrant youth. Education at theintensive margin is measured by two widely used standardized math and reading test scores,national percentile rankings on these tests and cumulative grade point average (GPA) in bothmiddle and high school. Our findings provide evidence that the academic achievement ofimmigrant children in early adolescence is an accurate predictor of later life outcomes. Wealso examine a novel hypothesis that relative academic performance of immigrant children inhigh school compared to middle school, which could be an indicator of change in adolescentaspirations and motivation as well as the degree of adaptation and assimilation to the hostcountry, has an effect on their adult outcomes even after controlling for the levels ofacademic performance in middle and high school. The results suggest that an improvementin GPA from middle school to high school is associated with favorable adult outcomes.Several sensitivity tests confirm the robustness of main findings.

Age at migration, language proficiency, and socioeconomic outcomes: evidence from Australia

This study estimates the causal effects of language proficiency on the economic and social integration of Australian immigrants. Identifying the effects of languages on socioeconomic outcomes is inherently difficult owing to the endogeneity of language skills. Using the phenomenon that younger children learn languages more easily than older children, we construct an instrumental variable for language proficiency. To achieve this, we consider the age at arrival of immigrants who came as children from Anglophone and non-Anglophone countries. We find a significant positive effect of English proficiency on wages and promotions among adults who immigrated to Australia as children. Higher levels of English proficiency are associated with increased risk-taking, more smoking, and more exercise for men, but have considerable health benefits for women. English language proficiency has a significant influence on partner choice and a number of social outcomes, as well as on children's outcomes, including their levels of academic achievement. The results are robust to alternative specifications, including accounting for between-sibling differences and alternative measures of English skills.

Effects of diet change on carbon and nitrogen stable-isotope ratios in blood cells and plasma of the long-nosed bandicoot (Perameles nasuta)

Carbon (C) and nitrogen (N) stable isotopes offer a powerful tool for assessing the extent of tissue assimilation of dietary components. However, the method relies on knowledge of diet-tissue isotopic discrimination and how quickly diet shifts become apparent in various tissues. In the present study, blood plasma and blood cells, tissues that are easily obtained under field conditions, were used to validate the stable isotope method over a period of 4-5 weeks using captive long-nosed bandicoots (Perameles nasuta). Diet-tissue discrimination effects appeared to be small. For C, derived diet-tissue isotopic discriminations were 1.4‰ for blood plasma and -0.2‰ for blood cells. For N the values were 2.8‰ and 2.1‰, respectively, and were independent of the nitrogen content of the food. C and N turnover measurements in the blood plasma and cells of the bandicoots indicated that blood plasma provides dietary information integrated over a period of ∼3 weeks, whereas blood cells give an impression of the assimilated diet over a period of as much as half a year. These turnover rates were low compared with the little information available for birds and eutherian mammals, and probably relate to the typically low metabolic rate of marsupials.
