An R2R3 MYB transcription factor associated with regulation of the anthocyanin biosynthetic pathway in Rosaceae

Background The control of plant anthocyanin accumulation is via transcriptional regulation of the genes encoding the biosynthetic enzymes. A key activator appears to be an R2R3 MYB transcription factor. In apple fruit, skin anthocyanin levels are controlled by a gene called MYBA or MYB1, while the gene determining fruit flesh and foliage anthocyanin has been termed MYB10. In order to further understand tissue-specific anthocyanin regulation we have isolated orthologous MYB genes from all the commercially important rosaceous species. Results We use gene specific primers to show that the three MYB activators of apple anthocyanin (MYB10/MYB1/MYBA) are likely alleles of each other. MYB transcription factors, with high sequence identity to the apple gene were isolated from across the rosaceous family (e.g. apples, pears, plums, cherries, peaches, raspberries, rose, strawberry). Key identifying amino acid residues were found in both the DNA-binding and C-terminal domains of these MYBs. The expression of these MYB10 genes correlates with fruit and flower anthocyanin levels. Their function was tested in tobacco and strawberry. In tobacco, these MYBs were shown to induce the anthocyanin pathway when co-expressed with bHLHs, while over-expression of strawberry and apple genes in the crop of origin elevates anthocyanins. Conclusions This family-wide study of rosaceous R2R3 MYBs provides insight into the evolution of this plant trait. It has implications for the development of new coloured fruit and flowers, as well as aiding the understanding of temporal-spatial colour change.

Neoliberal social inclusion? The agenda of the Australian Universities Community Engagement Alliance

University–community engagement (UCE) represents a hybrid discourse and a set of practices within contemporary higher education. As a modality of research and teaching, ‘engagement’ denotes the process of universities forming partnerships with external communities for the promised generation of mutually beneficial and socially responsive knowledge, leading to enhanced economic, social and cultural developments. A critical discourse analysis (Fairclough 2003. Analysing Discourse: Textual analysis for social research. London: Routledge) of the Australian Universities Community Engagement Alliance’s (AUCEA) ‘Position Paper’(2008 Universities and community engagement (Position paper 2008–2010)), as reported in this article, suggests that its uneasy synthesis of neoliberal, social inclusion and civic engagement discourses into a hybrid UCE discourse semantically privileges neoliberal forms of engagement. Perhaps, as a result, the AUCEA seems to have missed an opportunity to influence the Australian ‘widening participation’ debate on securing access and opportunity for marginalised students at universities and building social and cultural capital within their communities of origin.

A high performance liquid chromatography and electrospray ionization mass spectrometry method for the analysis of the natural medicine, Forsythia suspensa

Samples of Forsythia suspensa from raw (Laoqiao) and ripe (Qingqiao) fruit were analyzed with the use of HPLC-DAD and the EIS-MS techniques. Seventeen peaks were detected, and of these, twelve were identified. Most were related to the glucopyranoside molecular fragment. Samples collected from three geographical areas (Shanxi, Henan and Shandong Provinces), were discriminated with the use of hierarchical clustering analysis (HCA), discriminant analysis (DA), and principal component analysis (PCA) models, but only PCA was able to provide further information about the relationships between objects and loadings; eight peaks were related to the provinces of sample origin. The supervised classification models-K-nearest neighbor (KNN), least squares support vector machines (LS-SVM), and counter propagation artificial neural network (CP-ANN) methods, indicated successful classification but KNN produced 100% classification rate. Thus, the fruit were discriminated on the basis of their places of origin.

Therapeutic practice with refugee clients: a qualitative study of therapist experience

Background There is limited research on the subjective experience of therapists and their understanding of therapeutic process when working with people from refugee backgrounds. Objective The present study provides a qualitative account of therapists’ conceptions of therapeutic practice and experiences of working therapeutically with refugee clients. Method Participants were 12 mental health workers who had worked therapeutically with people from refugee backgrounds, with an average of 7.6 years (range 1.5-16 years) experience in this field. Participants completed a semi-structured interview and completed a brief quantitative survey. Findings Thematic analysis revealed a number of super-ordinate themes. Four key themes are explored in the current study: principles of therapeutic practice; therapy as a relational experience; the role of context in informing therapeutic work with refugee clients; and the impact of therapeutic work on the therapist. Discussion The results revealed the complexity and demands of working with people from refugee backgrounds. Further, the lack of research evidence for the methods of therapeutic practice described in the current study highlights the distinction between naturalistic therapeutic practice and the current state of the evidence regarding therapeutic interventions for refugee clients. The findings have important implications for training and supporting therapists to work with people who have fled their countries of origin and who have often been exposed to highly traumatic events.

Demand for ecolabeled seafood in the Japanese market: A conjoint analysis of the impact of information and interaction with other labels

The use of seafood ecolabels is expanding in the world marketplace, but so are labels indicating other product attributes, such as country of origin and wild vs. farmed. The interactive effects of these labels and attributes in evaluating consumers' preferences for ecolabeled seafood are relatively unexplored. In this paper we investigate (1) the direct and interactive effects of seafood ecolabels with other common fish labels, and (2) how consumers' perceptions about the state of marine stocks and the valuation of ecolabels may be affected by different information. We find moderate interactive effects between ecolabels and country of origin labels, whereas the valuation for seafood ecolabels is fairly high. In terms of information, we find that consumers' perceptions about fish stock levels changed (negatively) after receiving information on declining stock levels, and more sensationalized information led to increased change. However, valuation for a seafood ecolabel increases only when the information was perceived positively (credible/interesting); whereas exaggerated information (which was also perceived less credible) had insignificant effects on WTP.

A commentary on the global position of South African accounting research

The South African designation of Chartered Accountant is comparable to similar designations in most developed countries. However, the research outputs of Accountancy academics in South Africa seem to lag far behind those of their counterparts abroad. This article discusses the results of several inquiries into the status of South African Accounting research in a global context, and identifies several reasons and possible remedies for low research output.

The grapes of wrath: The Coonawarra dispute, geographical indications and international trade

The famous wine region of Coonawarra in South Australia has been promoted as ’Australia's other Red Centre', emphasizing its terra rossa soil and its cabernet sauvignon. In his atlas of the wine regions of Australia, John Beeston comments upon the rich and contested history of the region: ’Coonawarra is certainly the most famous cabernet sauvignon region in Australia, and some would argue, the most renowned wine region in Australia per se'. A reporter, Penelope Debelle, captures a sense of the legal conflict over the parameters of the boundaries of Coonawarra: ’Behind the name Coonawarra, an inglorious contest is being waged that pits the romance of South Australia's terra rossa cool-climate wine region against the cold commercial reality of the label.'This Chapter tells the story behind the Coonawarra litigation, addressing the parties to the dispute; the legal and historical context of the case; and the immediate impact case, as well as its lingering significance. It considers the ’Coonawarra' case as, very literally, a landmark in Australian jurisprudence in respect of intellectual property. This chapter engages in the methodology of ’legal storytelling'. In the field of new historicism, the use of anecdotes - petite histoire - has been seen as a useful way of challenging grand historical narratives. Joel Fineman has observed that the anecdote is ’the literary form or genre that uniquely refers to the real.' This chapter has three parts. Part 1 outlines the European Community - Australia Wine Agreement 1994, and the operation of the Australian Wine and Brandy Corporation Act 1980 (Cth). Part 2 considers the various stages of the dispute over the Coonawarra region - moving from the decision of the Geographical Indications Committee, to the ruling of the Administrative Appeals Tribunal; and the conclusive decision of the Full Court of the Federal Court of Australia. Part 3 examines the implications of the Coonawarra litigation for other wine regions of Australia - most notably, the King Valley in Victoria; but also the Hunter Valley in the New South Wales; and the Margaret River in Western Australia. The conclusion considers the ramifications of the European Community-Australia Wine Agreement 2007, which has been initialed by both sides.

Blame it on Rio: Biodiscovery, native title, and traditional knowledge

This article examines the legal responses to protect traditional knowledge of biodiversity in the wake of the Rio Convention on Biological Diversity. It considers the relative merits of the inter-locking regimes of contract law, environmental law, intellectual property law, and native title law. Part 1 considers the natural drug discovery industry in Australia. In particular, it looks at the operations of Amrad, Astra Zeneca R & D, and the Australian Institute of Marine Science. This section examines the key features of the draft regulations proposed under the Environment Protection and Biodiversity Conservation Act 1999 (Cth) - model contracts, informed consent, benefit-sharing, and ministerial discretion. The use of Indigenous Land Use Agreements in the context of access to genetic resources is also explored. Part 2 considers the role played by native title law in dealing with tangible and intangible property interests. The High Court decision in Western Australia v Ward considers the relationship between native title rights and cultural knowledge. The Federal Court case of Neowarra v Western Australia provides an intriguing gloss on this High Court decision. Part 3 looks at whether traditional knowledge of biodiversity can be protected under intellectual property law. It focuses upon reforms such as Senator Aden Ridgeway's proposed amendments to the Plant Breeder's Rights Act 1994 (Cth), and the push to make disclosure of origin a requirement of patent law.

Travelling bones: The repatriation of Indigenous ancestral remains

In the album Journey, Archie Roach -- the Australian Indigenous singer-songwriter hailing from Mooroopna in Victoria - has a melancholy song called ‘Travell’n Bones.' It is about the repatriation of Indigenous ancestral remains to their rightful home. This Chapter considers the legal, ethical, and cultural conflicts over Australian indigenous remains being held in museums, in Australia, the United Kingdom, the European Union, and the United States. James Nason comments: ‘The explosion of legal and extra legal attention on issues of cultural property and heritage was born of the frustration and anger of indigenous peoples whose rights and perspectives about cultural property and heritage issues had been largely absent and essentially unwanted by the museum of community.' Part I focuses upon disputes in Australia involving the repatriation of Indigenous Australian remains. In Bropho v HREOC, there was controversy over a cartoon, mocking the repatriation of the remains of Yagan, an Indigenous warrior, to Western Australia. There was a discussion about the operation of the Racial Discrimination Act 1975 (Cth), and the exemptions available from the operation of the regime. Part II considers the efforts by The Te Papa Tongarewa - the Museum of New Zealand - to repatriate Maori and Moriori ancestral remains to New Zealand, and to iwi communities of origin. The conclusion considers the relevance of the United Nations Declaration on the Rights of Indigenous Persons 2007, and issues raised by ventures such as the Genographic Project.

The dominant 55kDa allergen of the subtropical Bahia grass (Paspalum notatum) pollen is a group 13 pollen allergen, Pas n 13

Bahia grass, Paspalum notatum, is an important pollen allergen source with a long season of pollination and wide distribution in subtropical and temperate regions. We aimed to characterize the 55. kDa allergen of Bahia grass pollen (BaGP) and ascertain its clinical importance. BaGP extract was separated by 2D-PAGE and immunoblotted with serum IgE of a grass pollen-allergic patient. The amino-terminal protein sequence of the predominant allergen isoform at 55. kDa had similarity with the group 13 allergens of Timothy grass and maize pollen, Phl p 13 and Zea m 13. Four sequences obtained by rapid amplification of the allergen cDNA ends represented multiple isoforms of Pas n 13. The predicted full length cDNA for Pas n 13 encoded a 423 amino acid glycoprotein including a signal peptide of 28 residues and with a predicted pI of 7.0. Tandem mass spectrometry of tryptic peptides of 2D gel spots identified peptides specific to the deduced amino acid sequence for each of the four Pas n 13 cDNA, representing 47% of the predicted mature protein sequence of Pas n 13. There was 80.6% and 72.6% amino acid identity with Zea m 13 and Phl p 13, respectively. Reactivity with a Phl p 13-specific monoclonal antibody AF6 supported designation of this allergen as Pas n 13. The allergen was purified from BaGP extract by ammonium sulphate precipitation, hydrophobic interaction and size exclusion chromatography. Purified Pas n 13 reacted with serum IgE of 34 of 71 (48%) grass pollen-allergic patients and specifically inhibited IgE reactivity with the 55. kDa band of BaGP for two grass pollen-allergic donors. Four isoforms of Pas n 13 from pI 6.3-7.8 had IgE-reactivity with grass pollen allergic sera. The allergenic activity of purified Pas n 13 was demonstrated by activation of basophils from whole blood of three grass pollen-allergic donors tested but not control donors. Pas n 13 is thus a clinically relevant pollen allergen of the subtropical Bahia grass likely to be important in eliciting seasonal allergic rhinitis and asthma in grass pollen-allergic patients.

Rights and wrongs of Australian government asylum seeker policy

Worldwide, no fewer than 50 million people a year are now fleeing dangerous and often life threatening situations in their countries of origin (UNHCR, 2014c). As one part of this movement, thousands risk journeys through dangerous waters hoping to obtain asylum in Australia. However, Australian Government policies adopted since 2013 aim to ensure that no asylum seeker nor any of the 3,500 detainees held in offshore detention centres will ever be settled on the mainland. To this has now been added a declaration that none of the recent refugees or 6200 asylum seekers waiting in Indonesia in centres run by the United Nations High Commissioner for Refugees (UNHCR) will gain entry (Whyte, 2014a). These immigration policies differ dramatically from those adopted in earlier decades that produced the country’s decidedly multicultural identity. This article reviews these changing perspectives of Australian governments and communities within the context of international obligations and expectations; the experiences of those directly involved in border policing practices and in detention centres; and the attitudes of national media. Relations and conflicts among the interests of the different parties are discussed and the scope for less punitive responses to the plight of asylum seekers is examined. The authors then focus on alternative processes to better address the interests and objectives of legitimately interested parties by processes which successively examine, optimise and reconcile the concerns of each. In so doing, they aim to demonstrate that such methods of sequential problem solving can respond effectively to the multiple concerns of the many significant stakeholders involved in increasingly significant global issues, whereas recourse to such single-goal, top-down programs as are expressed in the government’s current determination to “Stop the boats” at all costs are unlikely to prove sustainable.

Bayesian predictive modeling and comparison of oil samples

Statistical comparison of oil samples is an integral part of oil spill identification, which deals with the process of linking an oil spill with its source of origin. In current practice, a frequentist hypothesis test is often used to evaluate evidence in support of a match between a spill and a source sample. As frequentist tests are only able to evaluate evidence against a hypothesis but not in support of it, we argue that this leads to unsound statistical reasoning. Moreover, currently only verbal conclusions on a very coarse scale can be made about the match between two samples, whereas a finer quantitative assessment would often be preferred. To address these issues, we propose a Bayesian predictive approach for evaluating the similarity between the chemical compositions of two oil samples. We derive the underlying statistical model from some basic assumptions on modeling assays in analytical chemistry, and to further facilitate and improve numerical evaluations, we develop analytical expressions for the key elements of Bayesian inference for this model. The approach is illustrated with both simulated and real data and is shown to have appealing properties in comparison with both standard frequentist and Bayesian approaches

A novel near-infrared spectroscopy and chemometrics method for rapid analysis of several chemical components and antioxidant activity of mint (mentha haplocalyx briq.) samples

A novel near-infrared spectroscopy (NIRS) method has been researched and developed for the simultaneous analyses of the chemical components and associated properties of mint (Mentha haplocalyx Briq.) tea samples. The common analytes were: total polysaccharide content, total flavonoid content, total phenolic content, and total antioxidant activity. To resolve the NIRS data matrix for such analyses, least squares support vector machines was found to be the best chemometrics method for prediction, although it was closely followed by the radial basis function/partial least squares model. Interestingly, the commonly used partial least squares was unsatisfactory in this case. Additionally, principal component analysis and hierarchical cluster analysis were able to distinguish the mint samples according to their four geographical provinces of origin, and this was further facilitated with the use of the chemometrics classification methods-K-nearest neighbors, linear discriminant analysis, and partial least squares discriminant analysis. In general, given the potential savings with sampling and analysis time as well as with the costs of special analytical reagents required for the standard individual methods, NIRS offered a very attractive alternative for the simultaneous analysis of mint samples.

Travel behaviours of immigrants in Queensland, Australia

The aim of this research is to determine if there is a significant difference in public transport usage between Australian-born and overseas-born travellers in South East Queensland and identify if further investigation into this demographic factor is necessary. Using the household travel survey data of Southeast Queensland, Australia, this paper analyses the travel behaviours of immigrants and non-immigrants in the region. The immigrant population is divided into six sub-groups based on their continent of origin. The analysis results suggest that immigrants are more likely to use public transit in Brisbane over other regions in the study. Overall, this research strongly suggests that in Australia, a higher proportion of the immigrant population is more likely to use public transit compared to the proportion of the local population.

Mitigating undesirable impacts in the marine environment: A review of market-based management measures

Internationally, marine biodiversity conservation objectives are having an increasing influence on the management of commercial fisheries. While this is largely being implemented through Marine Protected Areas (MPAs) other management measures, such as market based instruments (MBIs), have proved to be effective at managing target species catch in fisheries and reducing environmental impacts in industries such as mining and tourism. Market-based management measures aim to mitigate the impacts of activities by better aligning the incentives their participants face with the objectives of management, changing their behavior as a consequence. In this paper, we review the potential of MBIs as management tools to mitigate undesirable environmental impacts associated with commercial fishing. Where they exist, examples of previous applications are described and the factors that influence their applicability and effectiveness are discussed. Several fishing methods and impacts are considered and suggest that whilst no single approach is most appropriate in all circumstances either replacing or complementing existing management arrangements with MBIs has the potential to improve environmental performance. This has a number of implications. From the environmental perspective they should enable levels of undesirable impacts such as damage to sensitive habitat or the bycatch of protected species of turtles, marine mammals, and seabirds to be reduced. The increased flexibility MBIs allow industry when developing solutions also has the potential to reduce costs to both the industry and managers, improving the cost-effectiveness of regulation as a result. Further, in the increasingly relevant case of MPAs the need for publicly funded compensation, often paid to industry when vessels are excluded from grounds, may also be significantly reduced if improved environmental performance makes it possible for some industry members to continue operating.
