    plyranges: a grammar of genomic data transformation
    Lee, S ; Cook, D ; Lawrence, M (BMC, 2019-01-04)
    Bioconductor is a widely used R-based platform for genomics, but its host of complex genomic data structures places a cognitive burden on the user. For most tasks, the GRanges object would suffice, but there are gaps in the API that prevent its general use. By recognizing that the GRanges class follows "tidy" data principles, we create a grammar of genomic data transformation, defining verbs for performing actions on and between genomic interval data and providing a way of performing common data analysis tasks through a coherent interface to existing Bioconductor infrastructure. We implement this grammar as a Bioconductor/R package called plyranges.

    Editorial [AICCM Bulletin, 41(2)]
    Tse, N (Taylor & Francis, 2020-04-02)
    Papers in this volume focus on geographic locations drawn from Indonesia, Singapore, Taiwan, and the Eastern borders of Australia. In these parts of the world, we all know that there is a long record of active use and conservation of material culture through traditional systems, while the professionalised practice of conservation engendered by its existence, has a relatively recent history.

    Identification of cellulose nitrate based adhesive repairs in archaeological pottery of the University of Melbourne's Middle Eastern archaeological pottery collection using portable FTIR-ATR spectroscopy and PCA
    Noake, E ; Lau, D ; Nel, P (BMC, 2017-01-19)
    A previous study of the Cypriot pottery collection housed in the Ian Potter Museum of Art at the University of Melbourne found approximately two-thirds of adhesive repairs are primarily composed of cellulose nitrate (CN). This is of concern as CN has a limited lifespan (6–20 years), which has implications for the strategic management of the collection. To gain a greater understanding of the prevalence of CN based adhesive repairs in the archaeological context, the original FTIR-ATR spectroscopic survey was extended to incorporate the University’s Middle Eastern archaeological pottery collection. Micro-samples were removed from artefacts using acetone swabs. Analysis of adhesive FTIR spectra identified CN to be present not only as the primary polymer in approximately one-tenth of repairs, but also as a secondary polymer in poly(vinyl acetate) (PVAc) and acrylic adhesive formulations, observed as a weak peak at ~1656 cm−1. CN’s secondary presence in PVAc adhesive formulations is demonstrated using principal component analysis (PCA) and the diphenylamine spot test for CN. Re-analysis of adhesive IR spectra from the Cypriot pottery collection found CN to be present as a secondary polymer in this collection as well. It is concluded a combined methodology of collecting and identifying FTIR-ATR spectra of adhesive repairs from archaeological pottery collections followed by PCA analysis bring to light adhesive formulations which can inform the management of pottery collections.

    Tea: An Alternative Adsorbent for the Preservation of Cellulose Triacetate Film
    Nel, P ; Bell, J ; Newnham, M (Australian Institute for the Conversation of Cultural Material Inc, 2017)
    Cellulose triacetate (CTA) film, the main film base of the Twentieth Century, is inherently unstable, affected by autocatalytic deterioration through hydrolysis. The release of, and subsequent exposure to, acetic acid known as ‘vinegar syndrome’ accelerates deterioration, placing all cellulose acetate materials at risk or actively deteriorating. Preservation techniques rely on cold storage to slow deterioration or microenvironments with adsorbent materials to remove corrosives and/or pollutants. However, commercially available adsorbents can be expensive and difficult to access. This research investigated the potential for tea and tea waste to act as an alternative, low cost, accessible adsorbent for the preservation of CTA film. Adsorption capabilities of various tea varieties and treatments were compared with activated charcoal, silica gel and molecular sieves. Testing established tea as an effective adsorbent of water and acetic acid vapour, with an aversion to adsorption of the plasticiser dibutyl-phthalate. Use of tea waste also involves additional cost, sustainability and accessibility benefits along with lessened corrosive potential. These findings support tea as a potentially viable alternative adsorbent for the preservation of CTA film, requiring further research into optimum application systems.

    What is in the 'People's Interest'?" Discourses of Egalitarianism and 'Development as Compensation' in Contemporary Ecuador
    Fitz-Henry, E ; Rodriguez, D ; Gold, M ; Zagato, A (Berghahn Books, 2020)
    The left-wing Pink Tide movement that swept across Latin America seems now to be overturned, as a new wave of free-market thinkers emerge across the continent. This book analyses the emergence of corporate power within Latin America and the response of egalitarian movements across the continent trying to break open the constraints of the state. Through an ethnographically grounded and localized anthropological perspective, this book argues that at a time when the regular structures of political participation have been ruptured, the Latin American context reveals multiple expressions of egalitarian movements that strive (and sometimes momentarily manage) to break through the state’s apparatus.

    Shifting practice in domestic violence: child protection workers partnering with mothers
    Humphreys, C ; Kertesz, M ; Healey, L ; Mandel, D ; Zufferey, C ; Buchanan, F (Interdisciplinary Research in Motherhood, 2019-12-05)
    Child protection services have struggled with domestic and family violence (DV) and how to respond to it. Historically it has been slow to recognise the impact of domestic violence on children. Once identified, child protection services have been slow to recognise that affected children are usually best safeguarded by workers supporting the non-offending parent, typically, the child’s mother in situations of DFV. The focus on assessing mothers for their protection or failure to protect their children in the face of fathers who use violence has become characteristic of much child protection practice which has failed to engage constructively with the challenges of domestic violence. Many issues have emerged as problematic, highlighting the poor ‘fit’ between the traditional child protection lens and the demands of an effective response to domestic violence. These include: an exclusive focus on the ‘best interests’ of the child without due regard for two victims of domestic violence (child and usually the child’s mother); the lack of engagement with fathers who use violence; the necessities of engaging with diverse communities; the problems with developing effective domestic violence interventions when separation has not occurred. These are not the problems of an individual practitioner, but rather point to the structural and cultural change required by organisations to support workers to shift their practice. This chapter will draw on recent research (a national case reading of child protection files in Australia) to highlight the gaps in understanding the impacts of DV on parenting skills, and the gaps in recognising and documenting mothers’ strengths and efforts to keep their children safe. Sometimes this has involved mothers being deemed as ‘non-compliant’ with child protection instructions. An intersectional lens will be taken to explore a feminist perspective on child protection practice. The framework developed by Safe & Together™ will be used to inform the chapter and bring a feminist lens which is inclusive of the needs of children for agency, safety and protection. There is evidence that supporting the mother–child relationship is the most effective way of keeping children safe where there is domestic violence. Strategies required at an organisational and a practitioner level will be explored, including the need for a differential response to children exposed to DFV. This response recognises that not all children are significantly affected by DFV and not all mothers find their parenting significantly compromised. While partnering with mothers, it should be recognised that children may have different perspectives on violence and have their own views about what keeps them safe.
