Keller, Judith. "Songs of the Australian Landscape: The Art and Spirituality of Rosalie Gascoigne." Pacifica: Australasian Theological Studies 20, no. 3 (October 2007): 307–21. http://dx.doi.org/10.1177/1030570x0702000305.
Full textAbstract:
This article focuses upon the central motifs and symbols of the Australian abstract artist Rosalie Gascoigne (1917-1999) in an attempt to uncover the spirituality in her work, and to connect this with Australian spirituality and with spirituality in the wider Christian tradition. The author proposes such a connection to be the fruit of bringing to bear the religious imagination upon Gascoigne's work, that is, a capacity to attend to the contemplative, creative and sacramental layers in it. Such a capacity invites a response to the artist's work that is ultimately religious. For Australia to be known as land of the spirit ( Terra spiritus), theologians cannot neglect the work of artists such as Rosalie Gascoigne.

Abstract In March 2020, Michelle Ryan, Artistic Director of Restless Dance Theatre, an Australian dance company that includes both disabled and non-disabled dancers, was awarded Australia’s highest dance honour by the Australia Council, the federal arts funding body, for her transformative leadership of the company. Almost simultaneously, the very same Australia Council removed funding support for Restless, threatening the company’s survival. This essay examines Restless’s response to the fundamental incoherence of the Australia Council’s decision and situates it within the broader context of the company’s own evolving practice in disability art, which in effect saw it attempt to create policy in the field. I outline the government policy contexts that underpin both the funding cuts and Restless’s pivot to an alternate source of funding: the ideologically driven ‘culture wars’ underpinning the Coalition government’s hostility to the arts sector, and the establishment of a National Disability Insurance Scheme that enables individual ‘clients’ to access money for arts training. Finally, the essay examines the implications of a dance company receiving funding from a disability service provider rather than from a mainstream arts funding body, questioning whether this is a further ‘ghettoization’ of disability art.

Abstract Thinking about artistic representation as a form of political representation enables a better understanding of what can be seen and said, who has the ability to see it and say it, and how it is possible to know and do politics in different ways. In the case of Australia’s immigration system, this understanding is critical. Australia’s treatment of people seeking asylum and refugees is widely criticised by the international community as violating international human rights and humanitarian laws and norms. The legal and bureaucratic frameworks surrounding refugees in Australia not only render their stories largely invisible but continue to perpetrate harm and suffering which goes unaddressed. In the absence of state protection, artistic representation becomes an important intervention into the practices and narratives surrounding Australia’s treatment of people seeking asylum and refugees. In this article, I explore Hoda Afshar’s video and photographic artwork Remain (2018) which documents the experiences and struggles of a group of stateless men who were left to languish on Manus Island, Papua New Guinea, in the aftermath of the Australian government closing its Manus Regional Processing Centre. Remain is one of the only available avenues open to the men to share their stories and to communicate the harm caused by national policy and practices. I argue that the artistic representation of Remain becomes a crucial form of political representation in this aftermath; political representation which would not otherwise be possible.

Abstract From the nineteenth century, Sydney’s Art Gallery of New South Wales has been a marker of cultural ambition in Australia. This paper critically considers five large French paintings purchased at the end of the nineteenth century at significant expense by the gallery. Feted by contemporaries as examples of the French academic style, they formed part of plans to develop a representative collection to further understanding of art in the colony and, over time, they have taken on a rich role in the collective cultural memory. Through close examination of these paintings, their historical reception, criticism, reproduction and traces in the gallery’s archives this article reveals a history of taste, class and the formation of the cultural value of art. Using an object-based approach, it positions these works as evidence of changing cultural ideas within the context of a state collection to offer new insight into their status, the gallery itself, and the multiple roles of public art collections.

Full textAbstract:
Abstract In September 2018, the Federal Court of Australia found that a Victorian woman did not need her estranged husband’s consent to undergo in vitro fertilisation treatment (IVF) using donor sperm. The woman, who was 45 years of age, made an urgent application to the Court for permission to undergo IVF using donor sperm. In a single judge ruling, Griffiths J held that the requirement in the Assisted Reproductive Treatment Act 2008 (Vic) (‘ART Act’) for a married woman to obtain the consent of her husband discriminated against the woman in question on the basis of her marital status in contravention of the Commonwealth Sex Discrimination Act 1984 (Cth) (‘SD Act’). His Honour declared the Victorian law in this instance ‘invalid and inoperable’ by operation of section 109 of the Commonwealth Constitution to the extent it was inconsistent with the Commonwealth law. Although the declarations by the Federal Court were limited in their terms to the circumstances of the case, the judgment raises broader issues about equity of access to assisted reproductive treatment (ART) in Victoria. The issue of partner consent as a barrier to access to ART was specifically raised by an independent review of the ART Act in Victoria. The Victorian Government released an interim report late last year as a first stage of the review, which canvasses some options for reform. This raises a broader question as to whether prescriptive legislation imposing detailed access requirements for ART is necessary or even helpful.

Abstract STUDY QUESTION How has the performance of the European regional register of the European IVF-monitoring Consortium (EIM)/European Society of Human Reproduction and Embryology (ESHRE) evolved from 1997 to 2016, as compared to the register of the Centres for Disease Control and Prevention (CDC) of the USA and the Australia and New Zealand Assisted Reproduction Database (ANZARD)? SUMMARY ANSWER It was found that coherent and analogous changes are recorded in the three regional registers over time, with a different intensity and pace, that new technologies are taken up with considerable delay and that incidental complications and adverse events are only recorded sporadically. WHAT IS KNOWN ALREADY European data on ART have been collected since 1997 by EIM. Data collection on ART in Europe is particularly difficult due to its fragmented political and legal landscape. In 1997, approximately 78.1% of all known institutions offering ART services in 23 European countries submitted data and in 2016 this number rose to 91.8% in 40 countries. STUDY DESIGN, SIZE, DURATION We compared the changes in European ART data as published in the EIM reports (2001–2020) with those of the USA, as published by CDC, and with those of Australia and New Zealand, as published by ANZARD. PARTICIPANTS/MATERIALS, SETTING, METHODS We performed a retrospective analysis of the published EIM data sets spanning the 20 years observance period from 1997 to 2016, together with the published data sets of the USA as well as of Australia and New Zealand. By comparing the data sets in these three large registers, we analysed differences in the completeness of the recordings together with differences in the time intervals on the occurrence of important trends in each of them. Effects of suspected over- and under-reporting were also compared between the three registers. X2 log-rank analysis was used to assess differences in the data sets. MAIN RESULTS AND THE ROLE OF CHANCE During the period 1997–2016, the numbers of recorded ART treatments increased considerably (5.3-fold in Europe, 4.6-fold in the USA, 3.0-fold in Australia and New Zealand), while the number of registered treatment modalities rose from 3 to 7 in Europe, from 4 to 10 in the USA and from 5 to 8 in Australia and New Zealand, as published by EIM, CDC and ANZARD, respectively. The uptake of new treatment modalities over time has been very different in the three registers. There is a considerable degree of underreporting of the number of initiated treatment cycles in Europe. The relationship between IVF and ICSI and between fresh and thawing cycles evolved similarly in the three geographical areas. The freeze-all strategy is increasingly being adopted by all areas, but in Europe with much delay. Fewer cycles with the transfer of two or more embryos were reported in all three geographical areas. The delivery rate per embryo transfer in thawing cycles bypassed that in fresh cycles in the USA in 2012, in Australia and New Zealand in 2013, but not yet in Europe. As a result of these changing approaches, fewer multiple deliveries have been reported. Since 2012, the most documented adverse event of ART in all three registers has been premature birth (<37 weeks). Some adverse events, such as maternal death, ovarian hyperstimulation syndrome, haemorrhage and infections, were only recorded by EIM and ANZARD. LIMITATIONS, REASONS FOR CAUTION The methods of data collection and reporting were very different among European countries, but also among the three registers. The better the legal background on ART surveillance, the more complete are the data sets. Until the legal obligation to report is installed in all European countries together with an appropriate quality control of the submitted data the reported numbers and incidences should be interpreted with caution. WIDER IMPLICATIONS OF THE FINDINGS The growing number of reported treatments in ART, the higher variability in treatment modalities and the rising contribution to the birth rates over the last 20 years point towards the increasing impact of ART. High levels of completeness in data reporting have been reached, but inconsistencies and inaccuracies still remain and need to be identified and quantified. The current trend towards a higher diversity in treatment modalities and the rising impact of cryostorage, resulting in improved safety during and after ART treatment, require changes in the organization of surveillance in ART. The present comparison must stimulate all stakeholders in ART to optimize surveillance and data quality assurance in ART. STUDY FUNDING/COMPETING INTEREST(S) This study has no external funding and all costs are covered by ESHRE. There are no competing interests. TRIAL REGISTRATION NUMBER N/A.

Full textAbstract:
Reflecting on a specific case study commissioned for the 2020 Keir Choreographic Awards in Australia, this text investigates how the work De-Limit sought to negotiate the relationship between menial, process-driven labour and dance/installation art. Developed as a collaboration between dance maker Alison Currie and visual artist David Cross, the work interrogated how Walter Benjamin’s and Martin Heidegger’s ideas on boredom and suspended time, respectively, might offer new considerations of task-based practice. This study specifically seeks to test key thresholds in relation to task-orientated discourse with the insertion of a series of counter-moments informed by Freud’s thinking around the uncanny. Playing with ideas of staging and set making at the intersection of art and dance, this text also seeks to interrogate how the building of an art installation offers a frame in which to understand dance and its assorted modalities in different ways. De-Limit slips between functional and abstract, exploring live action as an unstable liminal space between labour and performance.

Full textAbstract:
Abstract This study draws on student engagement factors to examine the relationship between students’ non-school-based arts experiences on their intrinsic motivation and self-efficacy to participate in visual arts responding tasks. Visual arts responding in the curriculum includes learning about artists and artworks, decoding art and making critical judgements, and is important in building twenty-first century learning skills such as critical thinking and communication. A total of 266 Year 10 to 12 students from 18 schools in Western Australia (WA) participated in the quantitative research, which explored outside-school arts engagement as well as cognitive and psychological engagement factors in their current year of secondary schooling. The findings showed that while being an art consumer appears to impact on intrinsic motivation and self-efficacy, producing art as a hobby outside of school does not appear to do so. The research raised questions about links between practice and theory, and how to promote students’ engagement in responding.

Abstract: This paper critiques de Botton and Armstrong’s Art as Therapy project (2013-2015), a collaboration with art museums in Canada, the Netherlands, and Australia, in which labels in the gallery, as well a catalogue and website, explain how viewers might use works of art to serve therapeutic purposes in their lives. The paper argues that, instead of making art more accessible to those who, allegedly, do not find access to art on their own, the Art as Therapy project undermines the force and richness of art by first declaring it useless and inaccessible and then repurposing it as therapeutic life hack.KEYWORDS: Museum education; aesthetic experience; pedagogical intervention; interpretive freedom.Résumé: Cet article se veut une critique du projet Art as Therapy (2013-2015) de Botton et Armstrong, mené en collaboration avec des musées des beaux-arts canadiens, néerlandais et australiens, dans le cadre duquel les affichettes des musées, ainsi que catalogues et sites Web, expliquent aux visiteurs comment utiliser les œuvres d’art à des fins thérapeutiques dans leur quotidien. Dans cet article, je prétends que, plutôt que rendre l’art davantage accessible à ceux qui ne peuvent supposément y accéder de leur propre chef, le projet Art as Therapy sape la force et la richesse de l’art en le déclarant à prime abord inutile et inaccessible pour le transformer par la suite en « astuces de vie » thérapeutiquesMOTS CLES: Éducation muséale; d’expérience esthétique; intervention pédagogique; la liberté interprétative

Full textAbstract:
This paper gives a personal perspective on the application and relevance of generative processes to art production. This view is that of a computer programmer, rather than that of a user of computer programs written (or hardware constructed) by others. The programmer is in the unique position of being able to describe and manipulate abstract processes which may be used as a unique means of artistic expression. This gives a greater amount of freedom to the programmer/artist than is the case when he or she is limited by programmed procedures defined by others.Prior to the development of a formal means of specifying visual and aural events, a concrete machine or set of rules for their manipulation and a means of bringing these representations back into the world as physical events, abstract processes were things to be contemplated but not experienced. Musical and spatial notations employed by artists, engineers and others, in concert with the programming of computing hardware, have opened the way for those who wish to manipulate processes in their artistic practice.In order to focus study and practice in the area of such generative computer art, the Center for Electronic Media Art (CEMA) has been established in Melbourne, Australia. The Center has spawned an international conference series on generative/process-based electronic art called Iteration. The perceived roles of the Center and Iteration conferences are discussed in this paper.

Abstract STUDY QUESTION Do the epigenome-wide DNA methylation profiles of adolescents born from ART differ from the epigenome of naturally conceived counterparts? SUMMARY ANSWER No significant differences in the DNA methylation profiles of adolescents born from ART [IVF or ICSI] were observed when compared to their naturally conceived, similar aged counterparts. WHAT IS KNOWN ALREADY Short-term and longer-term studies have investigated the general health outcomes of children born from IVF treatment, albeit without common agreement as to the cause and underlying mechanisms of these adverse health findings. Growing evidence suggests that the reported adverse health outcomes in IVF-born offspring might have underlying epigenetic mechanisms. STUDY DESIGN, SIZE, DURATION The Growing Up Healthy Study (GUHS) is a prospective study that recruited 303 adolescents and young adults, conceived through ART, to compare various long-term health outcomes and DNA methylation profiles with similar aged counterparts from Generation 2 from the Raine Study. GUHS assessments were conducted between 2013 and 2017. The effect of ART on DNA methylation levels of 231 adolescents mean age 15.96 ± 1.59 years (52.8% male) was compared to 1188 naturally conceived counterparts, 17.25 ± 0.58 years (50.9% male) from the Raine Study. PARTICIPANTS/MATERIALS, SETTING, METHODS DNA methylation profiles from a subset of 231 adolescents (13–19.9 years) from the GUHS, generated using the Infinium Methylation Epic Bead Chip (EPIC) array were compared to 1188 profiles from the Raine Study previously measured using the Illumina 450K array. We conducted epigenome-wide association approach (EWAS) and tested for an association between the cohorts applying Firth’s bias reduced logistic regression against the outcome of ART versus naturally conceived offspring. Additionally, within the GUHS cohort, we investigated differences in methylation status in fresh versus frozen embryo transfers, cause of infertility as well as IVF versus ICSI conceived offspring. Following the EWAS analysis we investigated nominally significant probes using Gene Set Enrichment Analysis (GSEA) to identify enriched biological pathways. Finally, within GUHS we compared four estimates (Horvath, Hanuum, PhenoAge [Levine], and skin Horvath) of epigenetic age and their correlation with chronological age. MAIN RESULTS AND THE ROLE OF CHANCE Between the two cohorts, we did not identify any DNA methylation probes that reached a Bonferroni corrected P-value < 1.24E−0.7. When comparing IVF versus ICSI conceived adolescents within the GUHS cohort, after adjustment for participant age, sex, maternal smoking, multiple births, and batch effect, three methylation probes (cg15016734, cg26744878 and cg20233073) reached a Bonferroni correction of 6.31E−08. After correcting for cell count heterogeneity, two of the aforementioned probes remained significant and an additional two probes (cg 0331628 and cg 20235051) were identified. A general trend towards hypomethylation in the ICSI offspring was observed. All four measures of epigenetic age were highly correlated with chronological age and showed no evidence of accelerated epigenetic aging within their whole blood. LIMITATIONS, REASONS FOR CAUTION The small sample size coupled with the use of whole blood, where epigenetic differences may occur in other tissue. This was corrected by the utilized statistical method that accounts for imbalanced sample size between groups and adjusting for cell count heterogeneity. Only a small portion of the methylome was analysed and rare individual differences may be missed. WIDER IMPLICATIONS OF THE FINDINGS Our findings provide further reassurance that the effects of the ART manipulations occurring during early embryogenesis, existing in the neonatal period are indeed of a transient nature and do not persist into adolescence. However, we have not excluded that alternative epigenetic mechanisms may be at play.

Abstract. Narrative evidence contained within historical documents and inscriptions provides an important record of climate variability for periods prior to the onset of systematic meteorological data collection. A common approach used by historical climatologists to convert such qualitative information into continuous quantitative proxy data is through the generation of ordinal-scale climate indices. There is, however, considerable variability in the types of phenomena reconstructed using an index approach and the practice of index development in different parts of the world. This review, written by members of the PAGES (Past Global Changes) CRIAS working group – a collective of climate historians and historical climatologists researching Climate Reconstructions and Impacts from the Archives of Societies – provides the first global synthesis of the use of the index approach in climate reconstruction. We begin by summarising the range of studies that have used indices for climate reconstruction across six continents (Europe, Asia, Africa, the Americas, and Australia) as well as the world's oceans. We then outline the different methods by which indices are developed in each of these regions, including a discussion of the processes adopted to verify and calibrate index series, and the measures used to express confidence and uncertainty. We conclude with a series of recommendations to guide the development of future index-based climate reconstructions to maximise their effectiveness for use by climate modellers and in multiproxy climate reconstructions.

Abstract The field of bioaesthetics seeks to understand how modern humans may have first developed art appreciation and is informed by considering a broad range of fields including painting, sculpture, music and the built environment. In recent times there has been a diverse range of art and communication media representing bees, and such work is often linked to growing concerns about potential bee declines due to a variety of factors including natural habitat fragmentation, climate change, and pesticide use in agriculture. We take a broad view of human art representations of bees to ask if the current interest in artistic representations of bees is evidenced throughout history, and in different regions of the world prior to globalisation. We observe from the earliest records of human representations in cave art over 8,000 years old through to ancient Egyptian carvings of bees and hieroglyphics, that humans have had a long-term relationship with bees especially due to the benefits of honey, wax, and crop pollination. The relationship between humans and bees frequently links to religious and spiritual representations in different parts of the world from Australia to Europe, South America and Asia. Art mediums have frequently included the visual and musical, thus showing evidence of being deeply rooted in how different people around the world perceive and relate to bees in nature through creative practice. In modern times, artistic representations extend to installation arts, mixed-media, and the moving image. Through the examination of the diverse inclusion of bees in human culture and art, we show that there are links between the functional benefits of associating with bees, including sourcing sweet-tasting nutritious food that could have acted, we suggest, to condition positive responses in the brain, leading to the development of an aesthetic appreciation of work representing bees.

Abstract Urban metabolism is increasingly being adopted to guide city planning towards improved water, energy and material efficiency. Stakeholder participation in the adoption of this concept will be important, and hence effective communication will be crucial. This study aimed to determine how urban metabolism has been communicated and interpreted, with attention to water. The approach included (i) literature review, (ii) structured international interviews and (iii) thematic analysis. We demonstrate how diverse language, metaphors, methods, visual imagery, data and information have been used to communicate this complex topic. Maps, Sankey diagrams, concept figures, spider diagrams, pictorial flow diagrams, art, and animation have all been used. We observe barriers to communication in order to understand the communication techniques which may be effective, and clarify issues relating to awareness and target audiences. We include a discussion of the themes that emerged from the research that are relevant for integrated water planning and the power of visual imagery. Inconsistent language is influenced by widely different overarching metaphors which range from ‘organism’ to ‘ecosystem’ metabolism. Fragmented data are a major gap for shared understanding. The research provides new understanding of how stakeholders perceive urban water metabolism and its relationship to Integrated urban water management.

Abstract STUDY QUESTION What are the success rates for women returning to ART treatment in the hope of having a second ART-conceived child. SUMMARY ANSWER The cumulative live birth rate (LBR) for women returning to ART treatment was between 50.5% and 88.1% after six cycles depending on whether women commenced with a previously frozen embryo or a new ovarian stimulation cycle and the assumptions made regarding the success rates for women who dropped-out of treatment. WHAT IS KNOWN ALREADY Previous studies have reported the cumulative LBR for the first ART-conceived child to inform patients about their chances of success. However, most couples plan to have more than one child to complete their family and, for that reason, patients commonly return to ART treatment after the birth of their first ART-conceived child. To our knowledge, there are no published data to facilitate patient counseling and clinical decision-making regarding the success rates for these patients. STUDY DESIGN, SIZE, DURATION A population-based cohort study with 35 290 women who commenced autologous (using their own oocytes) ART treatment between January 2009 and December 2013 and achieved their first treatment-dependent live birth from treatment performed during this period. These women were then followed up for a further 2 years of treatment to December 2015, providing a minimum of 2 years and a maximum of 7 years of treatment follow-up. PARTICIPANTS/MATERIALS, SETTING, METHODS Cycle-specific LBR and cumulative LBR were calculated for up to six complete ART cycles (one ovarian stimulation and all associated transfers). Three cumulative LBR were calculated based on the likelihood of success in women who dropped-out of treatment (conservative, optimal and inverse probability-weighted (IPW)). A multivariable logistic regression model was used to predict the chance of returning to ART treatment for a second ART-conceived child, and a discrete time logistic regression model was used to predict the chance of achieving a second ART-conceived child up to a maximum of six complete cycles. The models were adjusted for patient characteristics and previous and current treatment characteristics. MAIN RESULTS AND THE ROLE OF CHANCE Among the women who had their first ART-conceived live birth, 15 325 (43%) returned to treatment by December 2015. LBRs were consistently better in women who recommenced treatment with a previously frozen embryo, compared to women who underwent a new ovarian stimulation cycle. After six complete cycles, plus any surplus frozen embryos, the cumulative LBR was between 60.9% (95% CI: 60.0–61.8%) (conservative) and 88.1% (95% CI: 86.7–89.5%) (optimal) [IPW 87.2% (95% CI: 86.2–88.2%)] for women who recommenced treatment with a frozen embryo, compared to between 50.5% (95% CI: 49.0–52.0%) and 69.8% (95% CI: 67.5–72.2%) [IPW 68.1% (95% CI: 67.3–68.9%)] for those who underwent a new ovarian stimulation cycle. The adjusted odds of a second ART-conceived live birth decreased for women ≥35 years, who waited at least 3 years before returning to treatment, or who required a higher number of ovarian stimulation cycles or double embryo transfer to achieve their first child. LIMITATIONS, REASONS FOR CAUTION Our estimates do not fully account for a number of individual prognostic factors, including duration of infertility, BMI and ovarian reserve. WIDER IMPLICATIONS OF THE FINDINGS This is the first study to report success rates for women returning to ART treatment to have second ART-conceived child. These age-specific success rates can facilitate individualized counseling for the large number of patients hoping to have a second child using ART treatment.

Abstract In December 2016 a group of researchers led by Professor Jiang Jiehong travelled to Jingdezhen as fieldwork for the Everyday Legend research project, funded by the Leverhulme Trust. Representing the White Rabbit Collection of Contemporary Chinese Art, Australia, I was invited to participate. This article developed from reflections on the fieldwork component of the research project, as well as the formal and informal discussions that took place, at the time and subsequently, in Shanghai, Birmingham, Groningen and London. In 2018, as a further development of this process of reflection, I conducted semi-structured interviews with two artists of different generations: the article examines how Liu Jianhua and Geng Xue approach the use of porcelain as a contemporary art material. Each has spent extensive periods of time in Jingdezhen and each is immersed in this particularly Chinese tradition. At the same time, each is identified (and identifies themselves) as practising in a global contemporary art context and participates in exhibitions and exchanges internationally. Considered in the context of current and historical discourses around global contemporaneity2 and its manifestations in twenty-first-century China, their work illuminates the key question that the Everyday Legend project was designed to examine: how can contemporary art and traditional Chinese craft practices intersect, informing and enriching each other? As representatives, respectively, of the generation who emerged into the first years of the post-Cultural Revolution Reform and Opening period, and of a younger generation educated partly outside China, they reveal how Chinese artists strategically negotiate local and global in positioning their work as contemporary reinventions of traditional forms and materiality.

Abstract Art gallery programs tailored to the needs of people living with dementia are becoming more popular worldwide. This study aimed to observe the effects of six consecutive weekly discussion-based small group visits to the National Gallery of Australia Art and Dementia program on the salivary cortisol (SC) diurnal rhythm, salivary interleukin-6, quality of life (QoL), depressive symptoms, and cognitive function. Twenty-five participants (17 female; mean age 84.6 ± 7.27 years) completed the study with data collection at baseline, post-intervention, and at a six-week follow-up. Statistical methods were selected based on data distribution. The waking to evening (WE) SC ratio was altered (p = 0.016) (Baseline: 1.35 (1.19, 1.64), Post-intervention: 1.72 (1.54, 1.96), Follow-up: 1.44 (1.22, 1.79)) in the 22 participants who provided viable saliva samples. The WE SC ratio was higher post-intervention compared with baseline (p = 0.011), indicating a more dynamic SC rhythm, but returned to baseline levels at follow-up (p = 0.020). Interleukin-6 levels were unchanged (p = 0.664). In the total sample, no improvements in QoL (Proxy) (p = 0.165) were observed. However, self-reported depressive symptoms differed (p = 0.006), decreasing post-intervention (2.00 (1.00, 2.00)) compared with baseline (3.00 (2.00, 4.50)) (p = 0.015), and verbal fluency was affected (p = 0.027), improving from baseline (2.00 (0.00, 3.00)) to post-intervention (2.00 (0.50, 4.00)) (p = 0.027). Art and Dementia programs appear to have quantifiable benefits, including improved hypothalamic-pituitary-adrenal axis function, justifying a longer controlled trial inclusive of physiological outcomes.

Abstract. The Indonesian archipelago is the gateway in the tropics connecting two oceans (Pacific and the Indian Ocean) and two continents (Asia and Australia). During the Indian Ocean Dipole 1997, record anomalous and unanticipated upwelling had occurred along the southern coasts of Java and Sumatra causing massive phytoplankton blooms. But the method/mode/process for such anomalous upwelling was not known. Using monthly SeaWifs chlorophyll-a anomalies, TOPEX Sea Surface Height (SSH) anomalies, Sea Surface Temperatures (SST) and currents from a state-of-the-art OGCM, we report the presence of a series of cyclonic eddies along southern coasts of Sumatra and Java during November, December 1997 and January 1998. Upwelling caused by these cyclonic eddies, as also supported by the SSH and SST anomalies, has been responsible for the phytoplankton blooms to persist and dissipate during the 3 months (November, December 1997 and January 1998).

Full textAbstract:
Abstract Homelessness is a global phenomenon that contributes to and exacerbates social exclusion and marginalisation. The objective of this study is to generate a rich description of the experience of participating in arts-based programming as told by adults experiencing homelessness using a qualitative interpretive meta-synthesis. The synthesis includes eight studies, using direct quotes provided by fifty-three individuals in Canada, the USA and Australia. Synthesis of the eight studies results in three themes that describe the experience of participating in arts-based programming across geographic locations and art mediums: ‘arts as healing’, ‘arts as advocacy’ and ‘arts as self-empowerment’. While social workers, homelessness service providers, arts-based educators and researchers may be intuitively aware of the power of the arts, the synergistic findings of these eight articles indicate its influence among marginally housed populations. Implications and opportunities for future research are discussed.

Full textAbstract:
Abstract STUDY QUESTION What is the number of oocytes where the maximum cumulative live birth rate per aspiration (CLBR) is observed during ART in women of different ages? SUMMARY ANSWER The maximum CLBR was observed when around 25 oocytes were retrieved in women between 18–35 years of age, around 9 oocytes in women more than 45 years of age and continued to increase beyond 30 oocytes in women between 36–44 years of age. WHAT IS KNOWN ALREADY The live birth rate per fresh or frozen/thaw embryo transfer (FET) procedure has traditionally been the main measure of ART success. However, with the introduction of highly efficient embryo cryopreservation methods, CLBR encompassing live delivery outcomes from the fresh and all subsequent FET following a single ovarian stimulation and oocyte collection is increasingly viewed as a more meaningful measure of treatment success. There is evidence suggesting that larger oocyte yields are associated with increased likelihood of cumulative live birth per aspiration. Whether this association is the same across female ages has not yet been properly investigated. STUDY DESIGN, SIZE, DURATION This is a large retrospective population-based cohort study using data from the Australian and New Zealand Assisted Reproduction Database (ANZARD). ANZARD contains information from all ART treatment cycles carried out in all fertility centres in Australia and New Zealand. Overall, 221 221 autologous oocyte aspiration cycles carried out between January 2009 to December 2015 were included in the analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS Cumulative live birth per aspiration was defined as at least one liveborn baby at ≥20 weeks gestation resulting from an ART aspiration cycle, including all fresh and FET resulting from the associated ovarian stimulation, until one live birth occurred or all embryos were used. Cycles where no oocytes were retrieved were excluded from analysis as there is no possibility of live birth. Analyses of data were performed using generalized estimating equations to account for the clustered nature of data (multiple cycles undertaken by a woman). Univariate and multivariable regression analysis was performed to identify and adjust for factors known to independently affect cumulative live birth per aspiration. An interaction term between female age and the number of oocytes retrieved was included to assess whether the age of the women was associated with a different optimal number of oocytes to achieve at least one live birth from an aspiration cycle (i.e. the effect-modifying role of female age). The likelihood of cumulative live birth per aspiration was calculated as odds ratios (ORs) with 95% CI. MAIN RESULTS AND THE ROLE OF CHANCE The median number of oocytes retrieved was 7 (interquartile range, 4–12) and median age of patients was 36 (interquartile range, 33–40). The overall CLBR was 32.2%. The results from the multivariable regression analysis showed that the number of oocytes retrieved remained a significant predictor (P < 0.001) of cumulative live birth per aspiration after adjusting for female age, parity and cycle count. Compared to the reference group of 10–14 oocytes retrieved, the adjusted odds for cumulative live birth per aspiration increased with the number of oocytes retrieved: 1–3 oocytes, 0.21 (95% CI, 0.20–0.22); 4–9 oocytes, 0.56 (95% CI, 0.55–0.58); 15–19 oocytes, 1.38 (95% CI, 1.34–1.43); 20–24 oocytes, 1.75 (95% CI, 1.67–1.84); and 2.10 (95% CI, 1.96–2.25) with more than 25 oocytes. After stratifying by female age group, the rate of increase in CLBR per additional oocyte retrieved was lower in the older age groups, indicating that higher oocyte yields were more beneficial in younger women. CLBR of patients in the <30 years and 30–34 years age groups appeared to reach a plateau (with only minimal increase in CLBR per additional oocyte retrieved) after retrieval of 25 oocytes at 73% and 72%, respectively, while CLBR of patients in the 35–39 years and 40–44 years age groups continued to increase with higher oocyte yields, reaching 68% and 40%, respectively, when 30 or more oocytes were retrieved. CLBR of patients aged 45 years and above remained consistently below 5%. Findings suggest that the number of oocytes retrieved where CLBR appears to be maximized is around 25 in women between 18–35 years, more than 30 in women between 36–44 years and around 9 in women 45 years and older. However, results for women aged 45 years and older may not be as robust due to the relatively small sample size available in this age group. LIMITATIONS, REASONS FOR CAUTION As with all large retrospective database studies, there are potential confounders that cannot be accounted for. Despite the current study being based on complete ascertainment of ART cycles across two countries, ovarian stimulation protocols, oocyte quality parameters and a number of important patient characteristics are not collected by ANZARD. Additionally, a small number of cycles were available for women over 45 years yielding more than 15 oocytes, making these estimates unreliable. WIDER IMPLICATIONS OF THE FINDINGS The results from this study demonstrate that the number of oocytes retrieved where the maximum CLBR is observed during ART is dependent on female age. This provides information for clinicians and patients to understand the modifying effect of age on the number of oocytes retrieved and the likelihood of success with ART.

Abstract Background While advances in treatment have dramatically improved the lives of people living with HIV (PLHIV), a number of important unmet needs remain. We conducted an international survey of PLHIV to explore their treatment experience and emotional challenges of ART. Methods Qualitative in-depth interviews were performed with PLHIV to identify key hypotheses. A steering group (led by community members) developed the survey tool which was fielded online from November 2016 to July 2017 in 8 high-income countries in North America (NA), Europe, and Australia. A mixed sampling/recruitment approach was used to ensure a broad cross-section of PLHIV. Respondents were screened for eligibility prior to receiving access to the online survey. Results 1111 PLHIV were surveyed (74% male, 41% 35–49 years; 39% from NA). The majority (98%) were currently taking ARTs with 53% taking a single tablet regimen. Of those on treatment, 87% were satisfied with their current ART. Overall, results for NA respondents were similar to the global results. Many participants reported emotional challenges associated with their daily HIV treatment experience: 66% agreed taking ART every day was a reminder of their HIV status; 25% agreed being tied to a daily medication limited their day-to-day life; and 29% agreed they felt stressed and under pressure to take their HIV medication at the right time every day. Those not “open” about their HIV status were more likely to feel stressed by their medication and felt that it limited them. 37% of participants frequently or quite often hid their HIV medication to avoid revealing their HIV status, particularly amongst those who reported experiencing stigma or high emotional impact of HIV. 89% felt that advances in treatment will improve their quality of life. Reducing long-term adverse effects of ART and lowering dosing frequency were considered the most important areas for improvement; this was similar across demographics such as country, age, and gender. Conclusion In this international survey of PLHIV, despite overall satisfaction with current ART, significant emotional burden and daily impact of treatment persists. PLHIV consider the reduction of long-term adverse effects and dosing frequency important areas for improving ART. Disclosures All authors: No reported disclosures.

Abstract. 2003 was a record year for wildfires worldwide. Severe forest fires killed four people, displaced 20 500 others and burnt 260 000 ha in South-East Australia in January 2003. The uncontrolled fires ignited in early January 2003 as a result of a prolonged El Niño drought in South-East Australia. Severe weather conditions resulted in a fast spread of the fires and poor air quality in a region where 70% of the population of Australia lives. We use state-of-art global chemistry and transport model GEOS-Chem in conjunction with ground- and space-based observations to study the ozone (O3) and aerosol enhancement due to fires. Firstly, the monthly mean surface O3 and Aerosol Optical Depth (AOD) in January 2003 are compared to January 2004 and, secondly, from sensitivity model simulations, four episodes are isolated and an attempt is made to quantify the contribution of the fires to air quality in south and South-East Australia. In January 2003 the observed monthly mean afternoon surface O3 in Victoria (VIC) and South Australia (SA) reached 27.5 ppb, which is 6.5 ppb (i.e. 30%) higher than in 2004. The simulated O3 is 29.5 ppb, which is 10 ppb higher than in 2004. While the model tends to overestimate the observed peak O3, it exhibits very good skill in reproducing the O3 temporal variability in January 2003 with a correlation of 0.83. In VIC, the air quality 4-h ozone (O3) standard exceedences are reported on 17, 24 and 25 January. On 12, 17, 24–25 and 29 January 2003, the observed O3 peaks above 40 ppb and the simulated fire contribution is higher than 10 ppb. During these 4 episodes, the range of observed O3 enhancement due to fires is 20–35 ppb, which is a factor of 3 to 5 higher than the monthly mean. The simulated fire O3 enhancement is in the range 15–50 ppb with a factor of 1.5 to 5 higher than the monthly mean. During two episodes, a well-formed surface wind channel stretches across the Tasman Sea facilitating the long range transport to New Zealand contributing to a 10% increase of surface O3. During the four episodes in January 2003, the observed AOD was up to a factor of five higher that the monthly mean AOD. The simulated and observed AODs agree on the spatial structure. Despite the model tendency to underestimate the AOD, it proves a useful tool in reconstructing the mostly patchy observations.

Abstract Background Because of progress in antiretroviral therapy (ART), fewer people with HIV experience virologic failure with multiclass resistance. We sought to estimate the prevalence of multiclass resistance since the introduction of INSTI-based regimens using a systematic literature review. Methods A systematic literature search using PubMed, Embase, and the Cochrane Library was conducted of articles published since 2008, the year when INSTI-based regimens for treatment-experienced people with HIV became widely used. Bibliographies of existing literature reviews, websites of European and International organizations reporting data on HIV and AIDS, and abstracts presented from 2016–2018 at conferences were searched to identify additional relevant studies. Using predefined criteria, two reviewers independently reviewed studies reporting multiclass (three-class or greater) resistance in persons with HIV infection who are treatment experienced and were either perinatally infected or infected as adults. Studies from Western Europe, Australia, Canada and the United States (US) using any type of resistance definitions and resistance tests were included. Results A total of 441 unique articles were identified, 343 were excluded during level 1 screening and 98 articles were included for full-text review. A total of 34 articles (11 US studies, 3 from Canada, 1 from Australia, and 19 from Western European countries.) met the inclusion criteria and were included in data extraction analysis. Over the past decade, a modest decrease in the prevalence of three-class (NNRTI, NRTI, PI) resistance was observed in studies from the United States and Canada, ranging from 8.3% in 2009 to 6.7% in 2014 (Figure 1). Western European countries and Australia showed similar trends. The prevalence of 4-class resistance (including INSTIs) with virologic failure in the current treatment era is low, less than 2% (Figure 2). Conclusion The prevalence of multiclass resistance has decreased over the past decade, with three-class resistance continuing to decline and four-class resistance rare. Although the population with treatment failure and no viable options for a suppressive regimen is currently small, this group of people with HIV are in urgent need of novel treatment options.

Abstract Background Modern antiretroviral therapy (ART) has reduced HIV associated morbidity and mortality, and allowed a similar treatment approach of aggressive lymphomas in PLWH to that of their HIV negative counterparts. Australia is an ethnically diverse country with a low HIV prevalence and an excellent population-wide ART coverage and adherence in PLWH. We aimed to describe the real-world Australian experience in managing PLWH diagnosed with diffuse large B cell lymphoma (DLBCL) and Burkitt lymphoma (BL), and compare our treatment approach and outcomes against international data. Methods This was a retrospective, multicenter study conducted by the Australasian Lymphoma Alliance across 6 centers in 5 states. HIV positive patients with biopsy proven BL and DLBCL, diagnosed between 1st January 2009 and 31st December 2019 were identified through each institution's database. Baseline patient and disease characteristics, treatment exposure and outcomes were extracted from hospital medical records. Descriptive statistics, and survival analyses were performed as appropriate. Results 44 patients (24 DLBCL, 20 BL) were included in the analysis. The median age was 52 years (range 32-78). The median follow-up was 1.8 years (range 0.1-13.1). 36 (82%) patients presented with advanced stage (III-IV) disease. 28 (64%) were defined as high-risk based on disease specific IPI scoring systems. The mean CD4 count was 334 cells/μL at diagnosis and 10 (23%) patients had a CD4 count of <100 cells/μL. 23 (52%) had a HIV viral load <50 copies/ml. 12 (27%) were diagnosed with HIV at the time of lymphoma diagnosis (Mean CD4 count 191 cells/μL, mean viral load 665,612 copies/ml). 41 (93%) patients received chemotherapy with curative intent and 39 (88%) received Rituximab. 37 (84%) were given concurrent ART and chemo(immuno)therapy. 11 (55%) of BL patients were treated with CODOX-M/IVAC or HyperCVAD followed by 6 (30%) with Da-EPOCH. 14 (58%) of DLBCL patients received CHOP-based therapy with 11 (45%) receiving more intensive regimens (Da-EPOCH, HyperCVAD or CODOX-M/IVAC). In the whole cohort, median number of chemotherapy cycles delivered was 6, 6, 4 and 3 for CHOP, Da-EPOCH, CODOX-M/IVAC and HyperCVAD respectively. CR rates after first-line curative intent therapy were 75% and 83% in BL and DLBCL respectively. All treatment response assessments were made by positron emission tomography. Grade 3-4 toxicity was significant higher in patients receiving intensive chemotherapy (77% vs 29%, p=0.015). Total treatment related mortality was 5% (2 died of bacterial sepsis). The 2-year OS was 77% (95% CI 61-88); 67% for BL (95% CI 46-88) and 81% for DLBCL (95% CI 53-90)]. 2-year PFS was 67% for BL (95% CI 40-83) and 77% for DLBCL (95% CI 53-89). An initial drop of mean CD4 count post treatment was observed (334 to 214 cells/μL), followed by a rise after 6 and 12 months (290 and 431 cells/μL respectively) (fig 1). At 6 months post chemotherapy, 83% of patients had a HIV viral load of <50 copies/ml with 40% and 83% achieving a CD4 count of >350 cells/μL and >200 cells/μL respectively. Conclusions A significant proportion of PLWH still present with aggressive lymphoma as an AIDS-defining event prior to HIV diagnosis, despite high levels of health education and healthcare availability. Our results appear equivalent to those for non-HIV patients with acceptable toxicity. Current Australian practice favors treating aggressive lymphomas in PLWH similarly to the HIV negative population, with the addition of concurrent ART. CD4+ T-cell-related immune reconstitution appears to recover within 6 months post-therapy. The OS of this cohort appears similar to the HIV negative population and published cohort studies (Coutinho AIDS 2013, Evens Blood 2019, Alderuccio Blood Adv 2021). Figure 1 Figure 1.

Abstract. Recently, long filamentous bacteria have been reported conducting electrons over centimetre distances in marine sediments. These so-called cable bacteria perform an electrogenic form of sulfur oxidation, whereby long-distance electron transport links sulfide oxidation in deeper sediment horizons to oxygen reduction in the upper millimetres of the sediment. Electrogenic sulfur oxidation exerts a strong impact on the local sediment biogeochemistry, but it is currently unknown how prevalent the process is within the seafloor. Here we provide a state-of-the-art assessment of its global distribution by combining new field observations with previous reports from the literature. This synthesis demonstrates that electrogenic sulfur oxidation, and hence microbial long-distance electron transport, is a widespread phenomenon in the present-day seafloor. The process is found in coastal sediments within different climate zones (off the Netherlands, Greenland, the USA, Australia) and thrives on a range of different coastal habitats (estuaries, salt marshes, mangroves, coastal hypoxic basins, intertidal flats). The combination of a widespread occurrence and a strong local geochemical imprint suggests that electrogenic sulfur oxidation could be an important, and hitherto overlooked, component of the marine cycle of carbon, sulfur and other elements.

Abstract. Mineral dust aerosol constitutes an important component of the Earth's climate system, not only on short timescales due to direct and indirect influences on the radiation budget but also on long timescales by acting as a fertilizer for the biosphere and thus affecting the global carbon cycle. For a quantitative assessment of its impact on the global climate, state-of-the-art atmospheric and aerosol models can be utilized. In this study, we use the ECHAM6.3-HAM2.3 model to perform global simulations of the mineral dust cycle for present-day (PD), pre-industrial (PI), and last glacial maximum (LGM) climate conditions. The intercomparison with marine sediment and ice core data, as well as other modeling studies, shows that the obtained annual dust emissions of 1221, 923, and 5159 Tg for PD, PI, and LGM, respectively, generally agree well with previous findings. Our analyses focusing on the Southern Hemisphere suggest that over 90 % of the mineral dust deposited over Antarctica are of Australian or South American origin during both PI and LGM. However, contrary to previous studies, we find that Australia contributes a higher proportion during the LGM, which is mainly caused by changes in the precipitation patterns. Obtained increased particle radii during the LGM can be traced back to increased sulfate condensation on the particle surfaces as a consequence of longer particle lifetimes. The meridional transport of mineral dust from its source regions to the South Pole takes place at different altitudes depending on the grain size of the dust particles. We find a trend of generally lower transport heights during the LGM compared to PI as a consequence of reduced convection due to colder surfaces, indicating a vertically less extensive Polar cell.

Abstract This article investigates the policy and practice of Australia's so-called ‘eugenic phase’ of border control embedded within the 1912 Immigration Act. It highlights the efforts of the first London-based Commonwealth Medical Officer - Dr William Perrin Norris - who designed a medical bureaucratic system intended to keep ‘defectives’ out of Australia. Norris' vision is revealed to be befitting of his character, experience, and a passion for uniformity which went beyond his legal jurisdiction.

Abstract This article reflects upon a mobile art ethnography that sought to understand and rethink some of the tensions around regional/rural experiences of the digital. Using creative practice-based methods, it provides new insights into this regional/urban divide through the motif of working mother commuter as digital wayfarer, a term used to define on/offline digital entanglement through the lived experience of quotidian wayfaring. It contributes to debates around mobile communication and mobile media studies by connecting conceptual analysis of mobilities and its relationship to regional commuting with a creative approach to movement, play and a sense of place. Much of the academic research on mobile media and internet studies stems from an urban focus rather than engaging in the unevenness of the online as is much of the experience in the rural region of North Central Victoria, Australia. Being a working mother commuter for almost a decade, the researcher also took an autobiographical approach to aspects of this project through the lens of digital wayfaring. The artefact used ethnographic case study methods and is a creative non/ fiction sound and moving imagery work made using the mobile phone, within the context of the regional Vline train. Utilising sonified global positioning system (GPS) data as part of the soundscape, it addressed problems in the production of this train activity (i. e. work, creativity, play, rest and playbour) regarding social and material participation of the commute infrastructure and overlaid internet connections. It showed how multisensorial art-making highlights the commute to be a journey to and from - and of - work, within the ecology of the Vline train, and therefore provides new ways of perceiving this copresent, mediated and entangled digital experience.

Abstract There is a need for automatic systems that can reliably detect, track and classify fish and other marine species in underwater videos without human intervention. Conventional computer vision techniques do not perform well in underwater conditions where the background is complex and the shape and textural features of fish are subtle. Data-driven classification models like neural networks require a huge amount of labelled data, otherwise they tend to over-fit to the training data and fail on unseen test data which is not involved in training. We present a state-of-the-art computer vision method for fine-grained fish species classification based on deep learning techniques. A cross-layer pooling algorithm using a pre-trained Convolutional Neural Network as a generalized feature detector is proposed, thus avoiding the need for a large amount of training data. Classification on test data is performed by a SVM on the features computed through the proposed method, resulting in classification accuracy of 94.3% for fish species from typical underwater video imagery captured off the coast of Western Australia. This research advocates that the development of automated classification systems which can identify fish from underwater video imagery is feasible and a cost-effective alternative to manual identification by humans.

Abstract STUDY QUESTION What was the utilization, effectiveness and safety of practices in ART globally in 2012 and what global trends could be observed? SUMMARY ANSWER The total number of ART cycles increased by almost 20% since 2011 and the main trends were an increase in frozen embryo transfers (FET), oocyte donation, preimplantation genetic testing and single embryo transfers (SET), whereas pregnancy and delivery rates (PR, DR) remained stable, and multiple deliveries decreased. WHAT IS KNOWN ALREADY ART is widely practiced throughout the world, but continues to be characterized by significant disparities in utilization, availability, practice, effectiveness and safety. The International Committee for Monitoring Assisted Reproductive Technologies (ICMART) annual world report provides a major tool for tracking trends in ART treatment for over 25 years and gives important data to ART professionals, public health authorities, patients and the general public. STUDY DESIGN, SIZE, DURATION A retrospective, cross-sectional survey on the utilization, effectiveness and safety of ART procedures performed globally during 2012 was carried out. PARTICIPANTS/MATERIALS, SETTING, METHODS Sixty-nine countries and 2600 ART clinics submitted data on ART cycles performed during the year 2012, and their pregnancy outcome, through national and regional ART registries. ART cycles and outcomes are described at country, regional and global levels. Aggregate country data were processed and analyzed based on methods developed by ICMART. MAIN RESULTS AND ROLE OF CHANCE A total of 1 149 817 ART cycles were reported for the treatment year 2012. After imputing data for missing values and non-reporting clinics in reporting countries, 1 948 898 cycles (an increase of 18.6% from 2011) resulted in >465 286 babies (+17.9%) in reporting countries. China did not report and is not included in this estimate. The best estimate of global utilization including China is ∼2.8 million cycles and 0.9 million babies. From 2011 to 2012, the number of reported aspirations and FET cycles increased by 6.9% and 16.0%, respectively. The proportion of women aged 40 years or older undergoing non-donor ART increased from 24.0% in 2011 to 25.2% in 2012. ICSI, as a percentage of non-donor aspiration cycles, increased from 66.5% in 2011 to 68.9% in 2012. The IVF/ICSI combined delivery rates per fresh aspiration and FET cycles were 19.8% and 22.1%, respectively. In fresh non-donor cycles, SET increased from 31.4% in 2011 to 33.7% in 2012, while the average number of transferred embryos decreased from 1.91 to 1.88, respectively—but with wide country variation. The rates of twin deliveries following fresh non-donor transfers decreased from 19.6% in 2011 to 18.0% in 2012, and the triplet rate decreased from 0.9% to 0.8%. In FET non-donor cycles, SET was 54.8%, with an average of 1.54 embryos transferred and twin and triplet rates of 11.1% and 0.4%, respectively. The cumulative DR per aspiration increased from 28.0% in 2011 to 28.9% in 2012. The overall perinatal mortality rate per 1000 births was 21.4 following fresh IVF/ICSI and 15.9 per 1000 following FET. LIMITATIONS, REASONS FOR CAUTION The data presented depend on the quality and completeness of data submitted by individual countries to ICMART directly or through regional registries. This report covers approximately two-thirds of` world ART activity, with a major missing country, China. Continued efforts to improve the quality and consistency of reporting ART data by registries are still needed, including the use of internationally agreed standard definitions (International Glossary of Infertility and Fertility Care). WIDER IMPLICATIONS OF THE FINDINGS The ICMART world reports provide the most comprehensive global statistical census and review of ART utilization, effectiveness, safety and quality. While ART treatment continues to increase globally, the wide disparities in access to treatment, procedures performed and embryo transfer practices warrant attention by clinicians and policy makers. With the increasing practice of SET and of freeze all and resulting increased proportion of FET cycles, it is clear that PR and DR per aspiration in fresh cycles do not give an overall accurate estimation of ART efficiency. It is time to use cumulative live birth rate per aspiration, combining the outcomes of FET cycles with the associated fresh cycle from which the embryos were obtained, and to obtain global consensus on this approach.

Abstract. Disastrous bushfires during the last months of 2019 and January 2020 affected Australia, raising the question to what extent the risk of these fires was exacerbated by anthropogenic climate change. To answer the question for southeastern Australia, where fires were particularly severe, affecting people and ecosystems, we use a physically based index of fire weather, the Fire Weather Index; long-term observations of heat and drought; and 11 large ensembles of state-of-the-art climate models. We find large trends in the Fire Weather Index in the fifth-generation European Centre for Medium-Range Weather Forecasts (ECMWF) Atmospheric Reanalysis (ERA5) since 1979 and a smaller but significant increase by at least 30 % in the models. Therefore, we find that climate change has induced a higher weather-induced risk of such an extreme fire season. This trend is mainly driven by the increase of temperature extremes. In agreement with previous analyses we find that heat extremes have become more likely by at least a factor of 2 due to the long-term warming trend. However, current climate models overestimate variability and tend to underestimate the long-term trend in these extremes, so the true change in the likelihood of extreme heat could be larger, suggesting that the attribution of the increased fire weather risk is a conservative estimate. We do not find an attributable trend in either extreme annual drought or the driest month of the fire season, September–February. The observations, however, show a weak drying trend in the annual mean. For the 2019/20 season more than half of the July–December drought was driven by record excursions of the Indian Ocean Dipole and Southern Annular Mode, factors which are included in the analysis here. The study reveals the complexity of the 2019/20 bushfire event, with some but not all drivers showing an imprint of anthropogenic climate change. Finally, the study concludes with a qualitative review of various vulnerability and exposure factors that each play a role, along with the hazard in increasing or decreasing the overall impact of the bushfires.

Abstract. Sea surface temperature (SST) reconstructions based on isoprenoid glycerol dialkyl glycerol tetraether (isoGDGT) distributions from the Eocene southwest (SW) Pacific Ocean are unequivocally warmer than can be reconciled with state-of-the-art fully coupled climate models. However, the SST signal preserved in sedimentary archives can be affected by contributions of additional isoGDGT sources. Methods now exist to identify and possibly correct for overprinting effects on the isoGDGT distribution in marine sediments. Here, we use the current proxy insights to (re-)assess the reliability of the isoGDGT-based SST signal in 69 newly analyzed and 242 reanalyzed sediments at Ocean Drilling Program (ODP) Site 1172 (East Tasman Plateau, Australia) following state-of-the-art chromatographic techniques. We compare our results with paleoenvironmental and paleoclimatologic reconstructions based on dinoflagellate cysts. The resulting ∼ 130 kyr resolution Maastrichtian–Oligocene SST record based on the TetraEther indeX of tetraethers with 86 carbon atoms (TEX86) confirms previous conclusions of anomalous warmth in the early Eocene SW Pacific and remarkably cool conditions during the mid-Paleocene. Dinocyst diversity and assemblages show a strong response to the local SST evolution, supporting the robustness of the TEX86 record. Soil-derived branched GDGTs stored in the same sediments are used to reconstruct mean annual air temperature (MAAT) of the nearby land using the Methylation index of Branched Tetraethers with 5-methyl bonds (MBT'5me) proxy. MAAT is consistently lower than SST during the early Eocene, independent of the calibration chosen. General trends in SST and MAAT are similar, except for (1) an enigmatic absence of MAAT rise during the Paleocene–Eocene Thermal Maximum and Middle Eocene Climatic Optimum, and (2) a subdued middle–late Eocene MAAT cooling relative to SST. Both dinocysts and GDGT signals suggest a mid-shelf depositional environment with strong river runoff during the Paleocene–early Eocene progressively becoming more marine thereafter. This trend reflects gradual subsidence and more pronounced wet/dry seasons in the northward-drifting Australian hinterland, which may also explain the subdued middle Eocene MAAT cooling relative to that of SST. The overall correlation between dinocyst assemblages, marine biodiversity and SST changes suggests that temperature exerted a strong influence on the surface-water ecosystem. Finally, we find support for a potential temperature control on compositional changes of branched glycerol monoalkyl glycerol tetraethers (brGMGTs) in marine sediments. It is encouraging that a critical evaluation of the GDGT signals confirms that most of the generated data are reliable. However, this also implies that the high TEX86-based SSTs for the Eocene SW Pacific and the systematic offset between absolute TEX86-based SST and MBT'5me-based MAAT estimates remain without definitive explanation.

As the title implies the paper deals with the architectural and design features of the Orthodox Churches of the Western Ukrainian Diaspora, the principles of their placement in the development of cities and towns. The purpose of the publication is to study the Orthodox architecture of the Ukrainian diaspora, to determine the main stages of formation, development of Orthodox Church building outside Ukraine.
The article spotlights a number of political, economic and social circumstances that have forced many Ukrainians to travel to other countries. The four largest waves of immigration have been identified. The importance of religion in the formation of the Ukrainian diaspora, which united immigrants, helped to organize their cultural and artistic aspects of life; revive traditions; to study the native Ukrainian language and be in the circle of like-minded people. Thus, Ukrainian Orthodox church architecture developed and became outside the ethnic Ukrainian lands.
At the moment, there is a lack of sufficient scientific base that covers the sacred development of the Ukrainian diaspora, especially Orthodox church architecture. The article presents scholars who have studied the architecture, art, culture and Orthodox shrines of the Ukrainian diaspora.
The article examines countries such as Canada, the United States, Australia and Western Europe. The author identifies architectural and design features and urban planning principles based on four architectural and spatial types.
Such stylistic trends as: eclectic were common; "Citation" of a certain style of architecture or "stylization"; creative reworking of historical styles of Ukrainian architecture "stylization"; modernist-abstract, which is characterized by geometrization and continuous simplification of form. To illustrate these statements, the author of the article developed diagrams and tables.
In conclusion, the purpose and objectives of the publication based on the studied temples were revealed. About 180 Orthodox churches in Canada, 60 churches in the United States, 12 Orthodox churches in Australia and sacred buildings in Western Europe of the Ukrainian diaspora were analyzed.

Abstract. Extreme wildfires are global phenomena that consistently result in loss of life and property and further impact the cultural, economic and political stability of communities. In their most severe form they cause widespread devastation of environmental assets and are capable of impacting the upper troposphere/lower stratosphere through the formation of a thunderstorm within the plume. Such fires are now often observed by a range of remote-sensing technologies, which together allow a greater understanding of a fire's complex dynamics. This paper considers one such fire that burnt in the Blue Mountains region of Australia in late November 2006, which is known to have generated significant pyrocumulonimbus clouds in a series of blow-up events. Observations of this fire are analysed in detail to investigate the localised processes contributing to extreme fire development. In particular, it has been possible to demonstrate for the first time that the most violent instances of pyroconvection were driven by, and not just associated with, atypical local fire dynamics, especially the fire channelling phenomenon, which arises due to an interaction between an active fire, local terrain attributes and critical fire weather and causes the fire to rapidly transition from a frontal to an areal burning pattern. The impacts of local variations in fire weather and of the atmospheric profile are also discussed, and the ability to predict extreme fire development with state-of-the-art tools is explored.

Abstract. The Last Interglacial (LIG; ca. 125 ka) is a period of interest for climate research as it is the most recent period of the Earth's history when the boreal climate was warmer than at present. Previous research, based on models and geological evidence, suggests that the LIG may have featured enhanced patterns of ocean storminess, but this remains hotly debated. Here, we apply state-of-the-art climate and hydrodynamic modeling to simulate changes in sea level extremes caused by storm surges, under LIG and pre-industrial climate forcings. Significantly higher seasonal LIG sea level extremes emerge for coastlines along northern Australia, the Indonesian archipelago, much of northern and eastern Africa, the Mediterranean Sea, the Gulf of Saint Lawrence, the Arabian Sea, the east coast of North America, and islands of the Pacific Ocean and of the Caribbean. Lower seasonal LIG sea level extremes emerge for coastlines along the North Sea, the Bay of Bengal, China, Vietnam, and parts of Central America. Most of these anomalies are associated with anomalies in seasonal sea level pressure minima and in eddy kinetic energy calculated from near-surface wind fields, and therefore seem to originate from anomalies in the meridional position and intensity of the predominant wind bands. In a qualitative comparison, LIG sea level extremes seem generally higher than those projected for future warmer climates. These results help to constrain the interpretation of coastal archives of LIG sea level indicators.

Abstract In 2016, the UK Parliament passed the Trade Union Act 2016 (TU Act 2016), which introduced new quorum and approval requirements for pre-strike ballots. In Australia, mandatory pre-strike ballots, including a quorum requirement, were first introduced in 2006. This article explains the key features of the Australian pre-strike ballot system and reports on quantitative and qualitative empirical research findings on the operation of the ballots process to analyse the majority and quorum requirements, mode of ballot (postal, attendance or electronic) and choice of ballot agent. Quorum is the biggest obstacle to Australian unions authorising strike action under the pre-strike ballot rules, and postal ballots fail to reach quorum at significantly higher rates than do attendance ballots. By introducing quorums and retaining the requirement that all pre-strike ballots must be conducted by post, the TU Act 2016 endorsed the two factors under the Australian regime most likely to impede the authorisation of strike action in a pre-strike ballot.

Abstract. One of the main tasks in 3D geological modeling is the boundary parametrization of the subsurface from geological observations and geophysical inversions. Several approaches have been developed for geometric inversion and joint inversion of geophysical datasets. However, the robust, quantitative integration of models and datasets with different spatial coverage, resolution, and levels of sparsity remains challenging. One promising approach for recovering the boundary of the geological units is the utilization of a level set inversion method with potential field data. We focus on constraining 3D geometric gravity inversion with sparse lower-uncertainty information from a 2D seismic section. We use a level set approach to recover the geometry of geological bodies using two synthetic examples and data from the geologically complex Yamarna Terrane (Yilgarn Craton, Western Australia). In this study, a 2D seismic section has been used for constraining the location of rock unit boundaries being solved during the 3D gravity geometric inversion. The proposed work is the first we know of that automates the process of adding spatially distributed constraints to the 3D level set inversion. In many hard-rock geoscientific investigations, seismic data are sparse, and our results indicate that unit boundaries from gravity inversion can be much better constrained with seismic information even though they are sparsely distributed within the model. Thus, we conclude that it has the potential to bring the state of the art a step further towards building a 3D geological model incorporating several sources of information in similar regions of investigation.

Abstract This paper discusses oral translation work carried out in Australia. It argues that the physical presence of the translator is a significant factor both for the act of translation and for the development of typologies of translation. In his highly readable and extremely thought-provoking book Grammatical Man Jeremy Campbell titles one of his chapters “The Struggle against Randomness” (Campbell, 1982:75). I believe that this is an apt definition of our particular concerns with the development of text typologies. I consider it a struggle because in my view we are still grappling with the randomness of phenomena; we are still in a high entropy state. The aim of this paper is to attempt to make a small contribution to the typology debate by outlining some observations of certain data which form part of the random world of texts; these data are different in at least two ways: one, they are derived from the Australian context and two, they refer to “oral translations” which, while being specific to the Australian context are firmly ensconced in the universe of oral translations. I intend to briefly describe the Australian context and then outline the characteristics of that context which sets it apart from others. I shall then discuss a theoretical framework for the observations which will be subsequently described and finally, I shall venture a possible avenue for further investigation.

Abstract. Accurate and long-term rainfall estimates are the main inputs for several applications, from crop modeling to climate analysis. In this study, we present a new rainfall data set (SM2RAIN-CCI) obtained from the inversion of the satellite soil moisture (SM) observations derived from the ESA Climate Change Initiative (CCI) via SM2RAIN (Brocca et al., 2014). Daily rainfall estimates are generated for an 18-year long period (1998–2015), with a spatial sampling of 0.25° on a global scale, and are based on the integration of the ACTIVE and the PASSIVE ESA CCI SM data sets.The quality of the SM2RAIN-CCI rainfall data set is evaluated by comparing it with two state-of-the-art rainfall satellite products, i.e. the Tropical Measurement Mission Multi-satellite Precipitation Analysis 3B42 real-time product (TMPA 3B42RT) and the Climate Prediction Center Morphing Technique (CMORPH), and one modeled data set (ERA-Interim). A quality check is carried out on a global scale at 1° of spatial sampling and 5 days of temporal sampling by comparing these products with the gauge-based Global Precipitation Climatology Centre Full Data Daily (GPCC-FDD) product. SM2RAIN-CCI shows relatively good results in terms of correlation coefficient (median value > 0.56), root mean square difference (RMSD, median value < 10.34 mm over 5 days) and bias (median value < −14.44 %) during the evaluation period. The validation has been carried out at original resolution (0.25°) over Europe, Australia and five other areas worldwide to test the capabilities of the data set to correctly identify rainfall events under different climate and precipitation regimes.The SM2RAIN-CCI rainfall data set is freely available at https://doi.org/10.5281/zenodo.846259.

Abstract The Beijing 2008 Forecast Demonstration Project (B08FDP) included a variety of nowcasting systems from China, Australia, Canada, and the United States. A goal of the B08FDP was to demonstrate state-of-the-art nowcasting systems within a mutual operational setting. The nowcasting systems were a mix of radar echo extrapolation methods, numerical models, techniques that blended numerical model and extrapolation methods, and systems incorporating forecaster input. This paper focuses on the skill of the nowcasting systems to forecast convective storms that threatened or affected the Summer Olympic Games held in Beijing, China. The topography surrounding Beijing provided unique challenges in that it often enhanced the degree and extent of storm initiation, growth, and dissipation, which took place over short time and space scales. The skill levels of the numerical techniques were inconsistent from hour to hour and day to day and it was speculated that without assimilation of real-time radar reflectivity and Doppler velocity fields to support model initialization, particularly for weakly forced convective events, it would be very difficult for models to provide accurate forecasts on the nowcasting time and space scales. Automated blending techniques tended to be no more skillful than extrapolation since they depended heavily on the models to provide storm initiation, growth, and dissipation. However, even with the cited limitations among individual nowcasting systems, the Chinese Olympic forecasters considered the B08FDP human consensus forecasts to be useful. Key to the success of the human forecasts was the development of nowcasting rules predicated on the character of Beijing convective weather realized over the previous two summers. Based on the B08FDP experience, the status of nowcasting convective storms and future directions are presented.

Abstract Moderate Resolution Imaging Spectroradiometer (MODIS) Level 2 observations from the Terra satellite are used to create a 3-yr climatology of cloud-top phase over a section of the Southern Ocean (south of Australia) and the North Pacific Ocean. The intent is to highlight the extensive presence of supercooled liquid water over the Southern Ocean region, particularly during summer. The phase of such clouds directly affects the absorbed shortwave radiation, which has recently been found to be “poorly simulated in both state-of-the-art reanalysis and coupled global climate models” (Trenberth and Fasullo). The climatology finds that supercooled liquid water is present year-round in the low-altitude clouds across this section of the Southern Ocean. Further, the MODIS cloud phase algorithm identifies very few glaciated cloud tops at temperatures above −20°C, rather inferring a large portion of “uncertain” cloud tops. Between 50° and 60°S during the summer, the albedo effect is compounded by a seasonal reduction in high-level cirrus. This is in direct contrast to the Bering Sea and Gulf of Alaska. Here MODIS finds a higher likelihood of observing warm liquid water clouds during summer and a reduction in the relative frequency of cloud tops within the 0° to −20°C temperature range. As the MODIS cloud phase product has limited ability to confidently identify cloud-top phase between −5° and −25°C, future research should include observations from the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) and other space-based sensors to help with the classification within this temperature range. Further, multiregion in situ verification of any remotely sensed observations is vital to further understanding the cloud phase processes.

Abstract Modern slavery is considered a widely recognized issue within labour-intensive markets of the construction industry. The recent introduction of the Modern Slavery Act 2018 (Cth) in Australia, has pragmatically pressured construction companies into publishing modern slavery statements that explore the methods in how they have managed to tackle and address the presence of modern slavery within their business and supply chains. This paper, as a part of an ongoing research project, conducts a content analysis to examine Australian modern slavery statements to identify common practices among Australian construction firms. For this purpose, we collected 62 modern slavery statements from construction companies that had issued such statements after the introduction of the regulatory requirement in Australia. The analysis uncovers diverse reporting practices in relation to the corporate commitment and governance, traceability and risk assessment, recruitment, purchasing practices, worker voice, remediation, and monitoring. The paper provides a baseline of understanding about the content and substance of modern slavery statements as a foundation for future research into developing an integrated framework for evaluating the performance on addressing modern slavery.

Abstract The Australian government has expressed concerns about various ‘data challenges’ confronting the public sector. Similar concerns are reverberating throughout the globe. Other governments continue to voice and act upon their own apprehensions about the threats posed to public and private society by attenuations to their nations’ ‘digital sovereignty’. This article critically examines the Australian government’s potential justifications, particularly under international trade law, for introducing digital sovereignty policies explicitly targeted at protecting government cyber systems and government data. We explore the risks and vulnerabilities of hosting government data offshore or with foreign cloud providers onshore. We find that Australia has sufficient latitude under its existing trade commitments, and within its current procurement framework, to introduce legitimate and proportionate digital sovereignty measures for the public sector.

Abstract Harris, P. T., Heap, A. D., Anderson, T. J., and Brooke, B. 2009. Comment on: Williams et al. (2009) “Australia's deep-water reserve network: implications of false homogeneity for classifying abiotic surrogates of biodiversity”. ICES Journal of Marine Science, 66: 214–224. – ICES Journal of Marine Science, 66: 2082–2085. Williams et al. (2009) report on new multibeam sonar bathymetry and underwater video data collected from submarine canyons and seamounts on Australia's southeast continental margin to “investigate the degree to which geomorphic features act as surrogates for benthic megafaunal biodiversity” (p. 214). The authors describe what they view as deficiencies in the design of the Marine Protected Areas (MPAs) in the southeast region of Australia, in which geomorphology information was employed as a surrogate to infer regional-scale patterns of benthic biodiversity. This comment is designed to support and underscore the importance of evaluating MPA designs and the validity of using abiotic surrogates such as geomorphology to infer biodiversity patterns, and also seeks to clarify some of the discrepancies in geomorphic terminologies and approaches used between the original study and the Williams et al. (2009) evaluation. It is our opinion that the MPA design criteria used by the Australian Government are incorrectly reported by Williams et al. (2009). In particular, we emphasize the necessity for consistent terminology and approaches when undertaking comparative analyses of geomorphic features. We show that the MPA selection criteria used by the Australian Government addressed the issues of false homogeneity described by Williams et al. (2009), but that final placement of MPAs was based on additional stakeholder considerations. Finally, we argue that although the Williams et al. (2009) study provides valuable information on biological distributions within seamounts and canyons, the hypothesis that geomorphic features (particularly seamounts and submarine canyons) are surrogates for benthic biodiversity is not tested explicitly by their study.

Full textAbstract:
Abstract Background Patient-delivered partner therapy (PDPT) is a method for an index patient to give treatment for genital chlamydia to their sexual partner(s) directly. In Australia, PDPT is considered suitable for heterosexual partners of men and women, but is not uniformly endorsed. We explored the policy environment for PDPT in Australia and considered how PDPT might become a routine option. Methods: Structured interviews were conducted with 10 key informants (KIs) representing six of eight Australian jurisdictions and documents relevant to PDPT were appraised. Interview transcripts and documents were analysed together, drawing on KIs’ understanding of their jurisdiction to explore our research topics, namely the current context for PDPT, challenges, and actions needed for PDPT to become routine. Results: PDPT was allowable in three jurisdictions (Victoria, New South Wales, Northern Territory) where State governments have formally supported PDPT. In three jurisdictions (Western Australia, Australian Capital Territory, Tasmania), KIs viewed PDPT as potentially allowable under relevant prescribing regulations; however, no guidance was available. Concern about antimicrobial stewardship precluded PDPT inclusion in the South Australian strategy. For Queensland, KIs viewed PDPT as not allowable under current prescribing regulations and, although a Medicine and Poisons Act was passed in 2019, it is unclear if PDPT will be possible under new regulations. Clarifying the doctor–partner treating relationship and clinical guidance within a care standard were viewed as crucial for PDPT uptake, irrespective of regulatory contexts. Conclusion: Endorsement and guidance are essential so doctors can confidently and routinely offer PDPT in respect to professional standards and regulatory requirements.

Abstract. South-eastern Australia has been identified by modelling studies as a hotspot of biogenic volatile organic compound (VOC) emissions; however, long-term observational VOC studies are lacking in this region. Here, 2.5 years of multi-axis differential optical absorption spectroscopy (MAX-DOAS) formaldehyde (HCHO) measurements in Australasia are presented, from Broadmeadows, in northern Melbourne, Australia, and from Lauder, a rural site in the South Island of New Zealand. Across the measurement period from December 2016 to November 2019, the mean formaldehyde columns measured by the MAX-DOAS were 2.50±0.61×1015 molec. cm−2 at Lauder and 5.40±1.59×1015 molec. cm−2 at Broadmeadows. In both locations, the seasonal cycle showed a pronounced peak in Austral summer (December–January–February) consistent with temperature-dependent formaldehyde production from biogenic precursor gases. The amplitude of the seasonal cycle was 0.7×1015 molec. cm−2 at Lauder, and it was 2.0×1015 molec. cm−2 at Broadmeadows. The Lauder MAX-DOAS HCHO measurements are compared with 27 months of co-located Fourier transform infrared (FTIR) observations. The seasonal variation of Lauder MAX-DOAS HCHO, smoothed by the FTIR averaging kernels, showed good agreement with the FTIR measurements, with a linear regression slope of 1.03 and an R2 of 0.66 for monthly averaged formaldehyde partial columns (0–4 km). In addition to ground-based observations, a clear way to address the VOC measurement gap in areas such as Australasia is with satellite measurements. Here, we demonstrate that the TROPOspheric Monitoring Instrument (TROPOMI) can be used to distinguish formaldehyde hotspots in forested and agricultural regions of south-eastern Australia. The MAX-DOAS measurements are also compared to TROPOMI HCHO vertical columns at Lauder and Melbourne; very strong monthly average agreement is found for Melbourne (regression slope of 0.61 and R2 of 0.95) and a strong agreement is found at Lauder (regression slope of 0.73 and R2 of 0.61) for MAX-DOAS vs. TROPOMI between May 2018 and November 2019. This study, the first long-term satellite comparison study using MAX-DOAS in the Southern Hemisphere, highlights the improvement offered by TROPOMI's high resolution over previous satellite products and provides the groundwork for future studies using ground-based and satellite DOAS for studying VOCs in Australasia.

Abstract A portion of human-caused carbon dioxide emissions will stay in the atmosphere for hundreds of years, raising temperatures and sea levels globally. Most nations’ emissions-reduction policies and actions do not seem to reflect this long-term threat, as collectively they point toward widespread permanent inundation of many developed areas. Using state-of-the-art new global elevation and population data, we show here that, under high emissions scenarios leading to 4 ∘C warming and a median projected 8.9 m of global mean sea level rise within a roughly 200- to 2000-year envelope, at least 50 major cities, mostly in Asia, would need to defend against globally unprecedented levels of exposure, if feasible, or face partial to near-total extant area losses. Nationally, China, India, Indonesia, and Vietnam, global leaders in recent coal plant construction, have the largest contemporary populations occupying land below projected high tide lines, alongside Bangladesh. We employ this population-based metric as a rough index for the potential exposure of the largely immovable built environment embodying cultures and economies as they exist today. Based on median sea level projections, at least one large nation on every continent but Australia and Antarctica would face exceptionally high exposure: land home to at least one-tenth and up to two-thirds of current population falling below tideline. Many small island nations are threatened with near-total loss. The high tide line could encroach above land occupied by as much as 15% of the current global population (about one billion people). By contrast, meeting the most ambitious goals of the Paris Climate Agreement will likely reduce exposure by roughly half and may avoid globally unprecedented defense requirements for any coastal megacity exceeding a contemporary population of 10 million.

AbstractA growing body of literature indicates that corporal punishment (CP) has the potential to adversely affect the mental and physical wellbeing of children in childhood as well as into adulthood. Corporal punishment of children in the home is legal in all states and territories in Australia, but not much is known about this type of family violence in the Australian context. This article presents a review of the literature currently available on the prevalence of CP of children in the home in Australia, covering online surveys, academic research, government data and grey literature. The role of online surveys is examined, and the lack of data available from government studies concerned with the wellbeing of children is also explored. There is found to be an overall lack of consistent data available on CP of children in the home in Australia, and this article calls on researchers and policymakers to further research and act on this aspect of family violence.
