The contribution of three components of nutrition knowledge to socio-economic differences in food purchasing choices

Objectives: To assess socio-economic differences in three components of nutrition knowledge, i.e. knowledge of (i) the relationship between diet and disease, (ii) the nutrient content of foods and (iii) dietary guideline recommendations; furthermore, to determine if socio-economic differences in nutrition knowledge contribute to inequalities in food purchasing choices. Design: The cross-sectional study considered household food purchasing,nutrition knowledge, socio-economic and demographic information. Household food purchasing choices were summarised by three indices, based on self-reported purchasing of sixteen groceries, nineteen fruits and twenty-one vegetables. Socio-economic position (SEP) was measured by household income and education. Associations between SEP, nutrition knowledge and food purchasing were examined using general linear models adjusted for age, gender, household type and household size. Setting: Brisbane, Australia in 2000. Subjects: Main household food shoppers (n 1003, response rate 66?4 %), located in fifty small areas (Census Collectors Districts). Results: Shoppers in households of low SEP made food purchasing choices that were less consistent with dietary guideline recommendations: they were more likely to purchase grocery foods comparatively higher in salt, sugar and fat, and lower in fibre, and they purchased a narrower range of fruits and vegetables. Those of higher SEP had greater nutrition knowledge and this factor attenuated most associations between SEP and food purchasing choices. Among nutrition knowledge factors, knowledge of the relationship between diet and disease made the greatest and most consistent contribution to explaining socio-economic differences in food purchasing. Conclusions: Addressing inequalities in nutrition knowledge is likely to reduce socio-economic differences in compliance with dietary guidelines. Improving knowledge of the relationship between diet and disease appears to be a particularly relevant focus for health promotion aimed to reduce socio-economic differences in diet and related health inequalities.

Creating a legal framework for copyright management of open access within the Australian academic and research sector

This chapter analyses the copyright law framework needed to ensure open access to outputs of the Australian academic and research sector such as journal articles and theses. It overviews the new knowledge landscape, the principles of copyright law, the concept of open access to knowledge, the recently developed open content models of copyright licensing and the challenges faced in providing greater access to knowledge and research outputs.

Pacific Rim treaty threatens public health: Patent law and medical procedures

Doctors, surgeons, and physicians around the Pacific Rim should be concerned by the proposals revealed by WikiLeaks in the Trans-Pacific Partnership (TPP). One of the most controversial features of the TPP is the proposal to provide for patent protection in respect of medical procedures. As Public Citizen observed, ‘Health providers, including surgeons, could be liable for the methods they use to treat patients.’ The civil society group noted: ‘Essentially, except for when a surgeon uses her bare hands, surgical methods would be patentable under the U.S. proposal.’ The TPP takes a broad approach to patents and medicine; lacks appropriate safeguards; and fails to address larger questions about equity, development, and human rights. Such a measure could result in greater litigation against medical professionals; barriers to access to medical procedures for patients; and skyrocketing health costs.

Trick or treaty?: The Australian debate over the Anti-Counterfeiting Trade Agreement

The secretive 2011 Anti-Counterfeiting Trade Agreement – known in short by the catchy acronym ACTA – is a controversial trade pact designed to provide for stronger enforcement of intellectual property rights. The preamble to the treaty reads like pulp fiction – it raises moral panics about piracy, counterfeiting, organised crime, and border security. The agreement contains provisions on civil remedies and criminal offences; copyright law and trademark law; the regulation of the digital environment; and border measures. Memorably, Susan Sell called the international treaty a TRIPS Double-Plus Agreement, because its obligations far exceed those of the World Trade Organization's TRIPS Agreement 1994, and TRIPS-Plus Agreements, such as the Australia-United States Free Trade Agreement 2004. ACTA lacks the language of other international intellectual property agreements, which emphasise the need to balance the protection of intellectual property owners with the wider public interest in access to medicines, human development, and transfer of knowledge and technology. In Australia, there was much controversy both about the form and the substance of ACTA. While the Department of Foreign Affairs and Trade was a partisan supporter of the agreement, a wide range of stakeholders were openly critical. After holding hearings and taking note of the position of the European Parliament and the controversy in the United States, the Joint Standing Committee on Treaties in the Australian Parliament recommended the deferral of ratification of ACTA. This was striking as representatives of all the main parties agreed on the recommendation. The committee was concerned about the lack of transparency, due process, public participation, and substantive analysis of the treaty. There were also reservations about the ambiguity of the treaty text, and its potential implications for the digital economy, innovation and competition, plain packaging of tobacco products, and access to essential medicines. The treaty has provoked much soul-searching as to whether the Trick or Treaty reforms on the international treaty-making process in Australia have been compromised or undermined. Although ACTA stalled in the Australian Parliament, the debate over it is yet to conclude. There have been concerns in Australia and elsewhere that ACTA will be revived as a ‘zombie agreement’. Indeed, in March 2013, the Canadian government introduced a bill to ensure compliance with ACTA. Will it be also resurrected in Australia? Has it already been revived? There are three possibilities. First, the Australian government passed enhanced remedies with respect to piracy, counterfeiting and border measures in a separate piece of legislation – the Intellectual Property Laws Amendment (Raising the Bar) Act 2012 (Cth). Second, the Department of Foreign Affairs and Trade remains supportive of ACTA. It is possible, after further analysis, that the next Australian Parliament – to be elected in September 2013 – will ratify the treaty. Third, Australia is involved in the Trans-Pacific Partnership negotiations. The government has argued that ACTA should be a template for the Intellectual Property Chapter in the Trans-Pacific Partnership. The United States Trade Representative would prefer a regime even stronger than ACTA. This chapter provides a portrait of the Australian debate over ACTA. It is the account of an interested participant in the policy proceedings. This chapter will first consider the deliberations and recommendations of the Joint Standing Committee on Treaties on ACTA. Second, there was a concern that ACTA had failed to provide appropriate safeguards with respect to civil liberties, human rights, consumer protection and privacy laws. Third, there was a concern about the lack of balance in the treaty’s copyright measures; the definition of piracy is overbroad; the suite of civil remedies, criminal offences and border measures is excessive; and there is a lack of suitable protection for copyright exceptions, limitations and remedies. Fourth, there was a worry that the provisions on trademark law, intermediary liability and counterfeiting could have an adverse impact upon consumer interests, competition policy and innovation in the digital economy. Fifth, there was significant debate about the impact of ACTA on pharmaceutical drugs, access to essential medicines and health-care. Sixth, there was concern over the lobbying by tobacco industries for ACTA – particularly given Australia’s leadership on tobacco control and the plain packaging of tobacco products. Seventh, there were concerns about the operation of border measures in ACTA. Eighth, the Joint Standing Committee on Treaties was concerned about the jurisdiction of the ACTA Committee, and the treaty’s protean nature. Finally, the chapter raises fundamental issues about the relationship between the executive and the Australian Parliament with respect to treaty-making. There is a need to reconsider the efficacy of the Trick or Treaty reforms passed by the Australian Parliament in the 1990s.

A mercurial treaty: The Trans-Pacific Partnership (# TPP) and the United States

According to the United States Trade Representative (USTR), Ron Kirk, the Trans-Pacific Partnership is “an ambitious, next-generation, Asia-Pacific trade agreement that reflects U.S. priorities and values”.

A Supplementary Submission on The Commonwealth's Treaty-Making Process

This supplementary submission highlights two new developments, which have arisen since the initial submission. First, it considers the publication of the draft Investment Chapter of the Trans-Pacific Partnership (TPP) by WikiLeaks. Second, it looks at the introduction of the fast-track trade promotion authority bill, the Bipartisan Congressional Priorities and Accountability Act of 2015, into the United States Congress. The two topics have been inter-linked to a certain extent.

Key Role of Fe2+ in Epithiospecifier Protein Activity.

The chemical nature of the hydrolysis products from the glucosinolate-myrosinase system depends on the presence or absence of supplementary proteins such as epithiospecifier proteins (ESPs). ESPs promote the formation of epithionitriles from terminal alkenyl glucosinolates and, as recent evidence suggests, simple nitriles at the expense of isothiocyanates. From a human health perspective isothiocyanates are the most important because they are major inducers of carcinogen-detoxifying enzymes. Fe2+ is an essential factor in ESP activity, although several recent studies have highlighted discrepancies in the understanding of the ESP-iron interaction. To investigate further the role iron species play in regulating ESP activity, four ESP-containing seedpowders were analyzed for ESP and myrosinase activities, endogenous iron content, and glucosinolate degradation products after the addition of iron species, specific chelators, and reducing agents. For the first time this paper shows the effect of these additions on the hydrolysis of individual glucosinolates that constitute the total pool. Aged seeds and 3-day seedlings were also tested to investigate the effects of seed storage and early plant development on iron levels and ESP activity. The four ESP-containing plant systems tested gave two distinctive responses, thus providing strong evidence that ESPs vary markedly in their Fe2+ requirement for activity. The results also indicated that reduction of ferric to ferrous iron drives variations in ESP activity during early plant development. The reverse oxidation reaction provided a convincing explanation for the loss of ESP activity during seed storage. Aged seeds produced seedlings with substantially lower ESP activity, and there was a concomitant loss in germination rate. It was concluded that manipulation of endogenous iron levels of ESP-containing plants could increase the conversion of glucosinolates to isothiocyanates and enhance potential health benefits.

Analysis of the barley bract suppression gene Trd1

A typical barley (Hordeum vulgare) floret consists of reproductive organs three stamens and a pistil, and non-reproductive organs-lodicules and two floral bracts, abaxial called 'lemma' and adaxial 'palea'. The floret is subtended by two additional bracts called outer or empty glumes. Together these organs form the basic structural unit of the grass inflorescence, a spikelet. There are commonly three spikelets at each rachis (floral stem of the barley spike) node, one central and two lateral spikelets. Rare naturally occurring or induced phenotypic variants that contain a third bract subtending the central spikelets have been described in barley. The gene responsible for this phenotype was called the THIRD OUTER GLUME1 (Trd1). The Trd1 mutants fail to suppress bract growth and as a result produce leaf-like structures that subtend each rachis node in the basal portion of the spike. Also, floral development at the collar is not always suppressed. In rice and maize, recessive mutations in NECK LEAF1 (Nl1) and TASSEL SHEATH1 (Tsh1) genes, respectively, have been shown to be responsible for orthologous phenotypes. Fine mapping of the trd1 phenotype in an F-3 recombinant population enabled us to position on the long arm of chromosome 1H to a 10 cM region. We anchored this to a conserved syntenic region on rice chromosome Os05 and selected a set of candidate genes for validation by resequencing PCR amplicons from a series of independent mutant alleles. This analysis revealed that a GATA transcription factor, recently proposed to be Trd1, contained mutations in 10 out of 14 independent trd1 mutant alleles that would generate non-functional TRD1 proteins. Together with genetic linkage data, we confirm the identity of Trd1 as the GATA transcription factor ortholog of rice Nl1 and maize Tsh1 genes.

A Soul for Europe? : Contributions of European Churches to the Forum of the Convention on the Future of Europe

The aim of this research was to study how European churches contributed to the shaping of the Constitutional Treaty during the work of the Convention on the future of Europe through the public discussion forum, established by the Convention for this specific purpose in the years 2002 2003. In particular, this study sought to uncover the areas of interest brought up by the churches in their contributions, the objectives they pursued, and the approaches and arguments they employed to reach those objectives. The data for this study comprised all official submissions by European churches and church alliances to the Forum, totalling 21 contributions. A central criterion for inclusion of the data was that the organization can reasonably be assumed to represent the official position of one or more Christian churches within the European Union before the 2004 expansion. The contributing churches and organizations represent the vast majority of Christians in Europe. The data was analyzed using primarily qualitative content analysis. The research approach was a combination of abductive and inductive inference. Based on the analysis a two-fold theoretical framework was adopted, focusing on theories of public religion, secularization and deprivatization of religion, and of legitimation and collective identity. The main areas of interest found in the contributions of the churches were the value foundation of the European Union, which is demanded to coherently permeate all policies and actions of the EU, and the social dimension of Europe, which must be given equal status to the political and economic dimensions. In both areas the churches claim significant experience and expertise, which they want to see recognized in the Constituional Treaty through a formally guaranteed status for churches and religious communities in the EU. In their contributions the churches show a strong determination to secure a significant role for both religion and religious communities in the public life of Europe. As for the role of religion, they point out to its potential as a motivating and cohesive force in society and as a building block for a collective European identity, which is still missing. Churches also pursue a substantial public role for themselves beyond the spiritual dimension, permeating the secular areas of the social, political and economic dimensions. The arguments in suppport of such role are embedded in their interest and expertise in spiritual and other fundamental values and their broad involvement in providing social services. In this context churches use expressions inclusive of all religions and convictions, albeit clearly advocating the primacy of Europe's Christian heritage. Based on their historical role, their social involvement and their spiritual mission they use the public debate on the Constitutional Treaty to gain formal legitimacy for the public status of religion and religious communities, both nationally and on a European level, through appropriate provisions in the constitutional text. In return they offer the European Union ways of improving its own legitimacy by reducing the democratic and ideological deficit of the EU and advancing the development a collective European identity.

Res Communis? A critical legal geography of outer space, Antarctica, and the deep seabed

This chapter provides a critical legal geography of outer Space, charting the topography of the debates and struggles around its definition, management, and possession. As the emerging field of critical legal geography demonstrates, law is not a neutral organiser of space, but is instead a powerful cultural technology of spatial production. Drawing on legal documents such as the Outer Space Treaty and the Moon Treaty, as well as on the analogous and precedent-setting legal geographies of Antarctica and the deep seabed, the chapter addresses key questions about the legal geography of outer Space, questions which are of growing importance as Space’s available satellite spaces in the geostationary orbit diminish, Space weapons and mining become increasingly viable, Space colonisation and tourism emerge, and questions about Space’s legal status grow in intensity. Who owns outer Space? Who, and whose rules, govern what may or may not (literally) take place there? Is the geostationary orbit the sovereign property of the equatorial states it supertends, as these states argued in the 1970s? Or is it a part of the res communis, or common property of humanity, which currently legally characterises outer Space? Does Space belong to no one, or to everyone? As challenges to the existing legal spatiality of outer Space emerge from spacefaring states, companies, and non-spacefaring states, it is particularly critical that the current spatiality of Space is understood and considered.

Kinetics of ceric ion oxidation of naphthalene and its derivatives. Formation of the radical cation intermediate in the rate limiting step

Ceric ammonium sulfate, CAS, oxidizes naphthalene to 1,4-naphthoquinone in essentially quantitative yield in CH3CN-dil. H2SO4. Stoichiometric studies indicate that 6 mol of CAS are required for the oxidation of 1 mol of naphthalene to 1,4-naphthoquinone. Kinetic investigations reveal that the reaction takes place through initial formation of a 1:1 complex of naphthalene and cerium(IV) in an equilibrium step followed by slow decomposition of the complex to naphthalene radical cation. Kinetic results on the effects of acid strength, polarity of the medium, temperature and substituents are in accordance with this mechanism. Further conversion of the radical cation into 1,4-naphthoquinone takes place in fast steps involving a further 5 mol of cerium(IV) and 2 mol of H2O.

Solution structure of BTK-2, a novel hK(v)1.1 inhibiting scorpion toxin, from the eastern Indian scorpion Mesobuthus tamulus

The three dimensional structure of a 32 residue three disulfide scorpion toxin, BTK-2, from the Indian red scorpion Mesobuthus tamulus has been determined using isotope edited solution NMR methods. Samples for structural and electrophysiological studies were prepared using recombinant DNA methods. Electrophysiological studies show that the peptide is active against hK(v)1.1 channels. The structure of BTK-2 was determined using 373 distance restraints from NOE data, 66 dihedral angle restraints from NOE, chemical shift and scalar coupling data, 6 constraints based on disulfide linkages and 8 constraints based on hydrogen bonds. The root mean square deviation (r.m.s.d) about the averaged co-ordinates of the backbone (N, C-alpha, C') and all heavy atoms are 0.81 +/- 0.23 angstrom and 1.51 +/- 0.29 angstrom respectively. The backbone dihedral angles (phi and psi) for all residues occupy the favorable and allowed regions of the Ramachandran map. The three dimensional structure of BTK-2 is composed of three well defined secondary structural regions that constitute the alpha-beta-beta, structural motif. Comparisons between the structure of BTK-2 and other closely related scorpion toxins pointed towards distinct differences in surface properties that provide insights into the structure-function relationships among this important class of voltage-gated potassium channel inhibiting peptides.

Conformational basis for substrate recognition and regulation of catalytic activity in Staphylococcus aureus nucleoside di-phosphate kinase

Nucleoside diphosphate kinases (NDK) are characterized by high catalytic turnover rates and diverse substrate specificity. These features make this enzyme an effective activator of a pro-drug an application that has been actively pursued for a variety of therapeutic strategies. The catalytic mechanism of this enzyme is governed by a conserved histidine that coordinates a magnesium ion at the active site. Despite substantial structural and biochemical information on NDK, the mechanistic feature of the phospho-transfer that leads to auto-phosphorylation remains unclear. While the role of the histidine residue is well documented, the other active site residues, in particular the conserved serine remains poorly characterized. Studies on some homologues suggest no role for the serine residue at the active site, while others suggest a crucial role for this serine in the regulation and quaternary association of this enzyme in some species. Here we report the biochemical features of the Staphylococcus aureus NDK and the mutant enzymes. We also describe the crystal structures of the apo-NDK, as a transition state mimic with vanadate and in complex with different nucleotide substrates. These structures formed the basis for molecular dynamics simulations to understand the broad substrate specificity of this enzyme and the role of active site residues in the phospho-transfer mechanism and oligomerization. Put together, these data suggest that concerted changes in the conformation of specific residues facilitate the stabilization of nucleotide complexes thereby enabling the steps involved in the ping-pong reaction mechanism without large changes to the overall structure of this enzyme.
