A workplace-based Participatory Action Research project to investigate the effectiveness of nutrition and physical activity interventions for truck drivers in six Queensland transport industry workplaces: 2012-2015

The Queensland Transport Industry Workplace Health Intervention project was a Participatory Action Research (PAR) project to investigate the effectiveness of workplace-based nutrition and physical activity health promotion interventions for truck drivers in transport industry workplaces in south-east Queensland. The project was conducted by a research team at the Queensland University of Technology (QUT), and was funded by the Queensland Government under the Healthier.Happier.Workplaces initiative.

Patent-busting: The public patent foundation, gene patents and the Seed Wars

This chapter considers the Public Patent Foundation as a novel institution in the patent framework. It contends that such a model can play a productive role in challenging the validity of high-profile patents; working as an amicus curiae in significant court cases; and also promoting patent law reform. However, there are limits to the ‘patent-busting’ of the Foundation. The not-for-profit legal services organization has only had the time and resources to challenge a number of noteworthy patents. Other jurisdictions – such as Australia – lack such public-spirited "patent-busting" entities. This chapter considers a number of key disputes involving the Public Patent Foundation. Part I examines the role of the Public Patent Foundation in the landmark dispute over Myriad Genetics’ patents in respect of breast cancer and ovarian cancer. Part II considers the role of the Public Patent Foundation in litigation between organic farmers and Monsanto. Part III examines the role of the Public Patent Foundation in larger debates about patent law reform in the United States – particularly looking at the Leahy-Smith America Invents Act 2011 (US). The conclusion contends that the patent-busting model of the Public Patent Foundation should be emulated in respect of other technological fields, and other jurisdictions – such as Australia. The initiative could also be productively applied to other forms of intellectual property – such as trade mark law, designs law, plant breeders’ rights, plant breeders’ rights, and access to genetic resources.

Hawai’i, clean energy, and climate action

Hawai’i is a leader in clean energy and climate action in the Pacific and the United States. With the Mauna Loa Observatory, Hawai’i has been at the forefront of climate research. The state has a special vulnerability to the impacts of climate change — particularly in respect of the marine environment, water resources, biodiversity, and human costs. Hawaii has promoted a Clean Energy initiative and passed legislation on climate adaptation. State and national leaders — most notably, United States Senator Brian Schatz — have shown great initiative in respect of clean energy and climate action. As such, it is worthwhile considering Hawaii as a case study of climate leadership in the Pacific and the United States.

The Jean Chretien Pledge to Africa act: Patent law and humanitarian aid

This article evaluates the implementation of the WTO General Council Decision in 2003, which resolved that developed nations could export patented pharmaceutical drugs to member states in order to address public health issues - such as HIV/AIDS, tuberculosis, malaria and other epidemics. The Jean Chretien Pledge to Africa Act 2004 (Canada) provides authorisation for the export of pharmaceutical drugs from Canada to developing countries to address public health epidemics. The European Union has issued draft regulations governing the export of pharmaceutical drugs. A number of European countries - including Norway, the Netherlands, France, and Switzerland - are seeking to pass domestic legislation to give force to the WTO General Council Decision. Australia has shown little initiative in seeking to implement such international agreements dealing with access to essential medicines. It is argued that Australia should implement humanitarian legislation to embody the WTO General Council Decision, emulating models in Canada, Norway, and the European Union. Ideally, there should be no right of first refusal; the list of pharmaceutical drugs should be open-ended; and the eligible importing countries should not be limited to members of the WTO.

Genome-wide interaction analysis reveals replicated epistatic effects on brain structure

The discovery of several genes that affect the risk for Alzheimer's disease ignited a worldwide search for single-nucleotide polymorphisms (SNPs), common genetic variants that affect the brain. Genome-wide search of all possible SNP-SNP interactions is challenging and rarely attempted because of the complexity of conducting approximately 1011 pairwise statistical tests. However, recent advances in machine learning, for example, iterative sure independence screening, make it possible to analyze data sets with vastly more predictors than observations. Using an implementation of the sure independence screening algorithm (called EPISIS), we performed a genome-wide interaction analysis testing all possible SNP-SNP interactions affecting regional brain volumes measured on magnetic resonance imaging and mapped using tensor-based morphometry. We identified a significant SNP-SNP interaction between rs1345203 and rs1213205 that explains 1.9% of the variance in temporal lobe volume. We mapped the whole brain, voxelwise effects of the interaction in the Alzheimer's Disease Neuroimaging Initiative data set and separately in an independent replication data set of healthy twins (Queensland Twin Imaging). Each additional loading in the interaction effect was associated with approximately 5% greater brain regional brain volume (a protective effect) in both Alzheimer's Disease Neuroimaging Initiative and Queensland Twin Imaging samples.

Genome-wide association identifies genetic variants associated with lentiform nucleus volume in N = 1345 young and elderly subjects

Deficits in lentiform nucleus volume and morphometry are implicated in a number of genetically influenced disorders, including Parkinson's disease, schizophrenia, and ADHD. Here we performed genome-wide searches to discover common genetic variants associated with differences in lentiform nucleus volume in human populations. We assessed structural MRI scans of the brain in two large genotyped samples: the Alzheimer's Disease Neuroimaging Initiative (ADNI; N = 706) and the Queensland Twin Imaging Study (QTIM; N = 639). Statistics of association from each cohort were combined meta-analytically using a fixed-effects model to boost power and to reduce the prevalence of false positive findings. We identified a number of associations in and around the flavin-containing monooxygenase (FMO) gene cluster. The most highly associated SNP, rs1795240, was located in the FMO3 gene; after meta-analysis, it showed genome-wide significant evidence of association with lentiform nucleus volume (PMA = 4. 79 × 10-8). This commonly-carried genetic variant accounted for 2. 68 % and 0. 84 % of the trait variability in the ADNI and QTIM samples, respectively, even though the QTIM sample was on average 50 years younger. Pathway enrichment analysis revealed significant contributions of this gene to the cytochrome P450 pathway, which is involved in metabolizing numerous therapeutic drugs for pain, seizures, mania, depression, anxiety, and psychosis. The genetic variants we identified provide replicated, genome-wide significant evidence for the FMO gene cluster's involvement in lentiform nucleus volume differences in human populations.

Discovery and replication of gene influences on brain structure using LASSO regression

We implemented least absolute shrinkage and selection operator (LASSO) regression to evaluate gene effects in genome-wide association studies (GWAS) of brain images, using an MRI-derived temporal lobe volume measure from 729 subjects scanned as part of the Alzheimer's Disease Neuroimaging Initiative (ADNI). Sparse groups of SNPs in individual genes were selected by LASSO, which identifies efficient sets of variants influencing the data. These SNPs were considered jointly when assessing their association with neuroimaging measures. We discovered 22 genes that passed genome-wide significance for influencing temporal lobe volume. This was a substantially greater number of significant genes compared to those found with standard, univariate GWAS. These top genes are all expressed in the brain and include genes previously related to brain function or neuropsychiatric disorders such as MACROD2, SORCS2, GRIN2B, MAGI2, NPAS3, CLSTN2, GABRG3, NRXN3, PRKAG2, GAS7, RBFOX1, ADARB2, CHD4, and CDH13. The top genes we identified with this method also displayed significant and widespread post hoc effects on voxelwise, tensor-based morphometry (TBM) maps of the temporal lobes. The most significantly associated gene was an autism susceptibility gene known as MACROD2.We were able to successfully replicate the effect of the MACROD2 gene in an independent cohort of 564 young, Australian healthy adult twins and siblings scanned with MRI (mean age: 23.8±2.2 SD years). Our approach powerfully complements univariate techniques in detecting influences of genes on the living brain.

A commonly carried genetic variant in the delta opioid receptor gene, OPRD1, is associated with smaller regional brain volumes: Replication in elderly and young populations

Delta opioid receptors are implicated in a variety of psychiatric and neurological disorders. These receptors play a key role in the reinforcing properties of drugs of abuse, and polymorphisms in OPRD1 (the gene encoding delta opioid receptors) are associated with drug addiction. Delta opioid receptors are also involved in protecting neurons against hypoxic and ischemic stress. Here, we first examined a large sample of 738 elderly participants with neuroimaging and genetic data from the Alzheimer's Disease Neuroimaging Initiative. We hypothesized that common variants in OPRD1 would be associated with differences in brain structure, particularly in regions relevant to addictive and neurodegenerative disorders. One very common variant (rs678849) predicted differences in regional brain volumes. We replicated the association of this single-nucleotide polymorphism with regional tissue volumes in a large sample of young participants in the Queensland Twin Imaging study. Although the same allele was associated with reduced volumes in both cohorts, the brain regions affected differed between the two samples. In healthy elderly, exploratory analyses suggested that the genotype associated with reduced brain volumes in both cohorts may also predict cerebrospinal fluid levels of neurodegenerative biomarkers, but this requires confirmation. If opiate receptor genetic variants are related to individual differences in brain structure, genotyping of these variants may be helpful when designing clinical trials targeting delta opioid receptors to treat neurological disorders.

Discovery and replication of dopamine-related gene effects on caudate volume in young and elderly populations (N1198) using genome-wide search

The caudate is a subcortical brain structure implicated in many common neurological and psychiatric disorders. To identify specific genes associated with variations in caudate volume, structural magnetic resonance imaging and genome-wide genotypes were acquired from two large cohorts, the Alzheimer's Disease NeuroImaging Initiative (ADNI; N=734) and the Brisbane Adolescent/Young Adult Longitudinal Twin Study (BLTS; N=464). In a preliminary analysis of heritability, around 90% of the variation in caudate volume was due to genetic factors. We then conducted genome-wide association to find common variants that contribute to this relatively high heritability. Replicated genetic association was found for the right caudate volume at single-nucleotide polymorphism rs163030 in the ADNI discovery sample (P=2.36 × 10 -6) and in the BLTS replication sample (P=0.012). This genetic variation accounted for 2.79 and 1.61% of the trait variance, respectively. The peak of association was found in and around two genes, WDR41 and PDE8B, involved in dopamine signaling and development. In addition, a previously identified mutation in PDE8B causes a rare autosomal-dominant type of striatal degeneration. Searching across both samples offers a rigorous way to screen for genes consistently influencing brain structure at different stages of life. Variants identified here may be relevant to common disorders affecting the caudate.

'Create a better online you': Designing online learning resources to develop undergraduate social media skills

‘Create a Better Online You’ (CBOY) is an emerging initiative from QUT Library. CBOY focusses on developing the social media skills of undergraduates at QUT. While many students will have encountered ‘cybersafety’ training in primary or secondary school, a comprehensive environmental scan revealed little in the way of social media resources targeted at undergraduates. In particular, there was little to no focus on the ways in which social media could be used strategically to develop a positive online reputation and enhance chances of employability post tertiary education. The resources created as part of CBOY are the result of a literature review, environmental scan, and discussions with staff and students at QUT. Following the comprehensive environmental scan, it appears that CBOY represents one of the first free, openly accessible, interactive resources targeting the social media skills of undergraduates.

Implementing a holistic process for embedding sustainability: A case study in first year engineering, Monash University, Australia

While there is clear recognition of the need to incorporate sustainable development into university curricula, there is limited research that examines how to achieve that integration or evaluates its impacts on student learning. This paper responds to these knowledge gaps through a case study of curriculum renewal that involved embedding sustainability into a first year engineering curriculum. The initiative was guided by a deliberative and dynamic model for curriculum renewal that brought together internal and external stakeholders through a structured sequence of facilitated workshops and meetings. That process identified sustainability-related knowledge and skills relevant for first year engineering, and faculty members teaching in the first year program were guided through a process of curriculum renewal to meet those needs. The process through which the whole of curriculum renewal was undertaken is innovative and provides a case study of precedent in the field of education for sustainability. The study demonstrates the contribution that can be made by a web-based sustainability portal in supporting curriculum renewal. Learning and teaching outcomes were evaluated through ‘before and after surveys’ of the first year engineering students. Statistically significant increases in student's self-reported knowledge of sustainability were measured as a result of exposure to the renewed first year curriculum and this confirmed the value of the initiative in terms of enhancing student learning. While applied in this case to engineering, the process to achieve integration of sustainability into the curriculum approach is likely to have value for other academic disciplines. Considering student performance on assignments and exam questions relating to sustainability would provide a stronger basis for future research to understand the impact of initiatives like this on student learning.

Global rules on conflict-of-laws matters in international insolvency law cases: An Australian perspective

The 2012 Report “Transnational Insolvency: Global Principles for Co-operation in International Insolvency Cases” – commissioned by The American Law Institute in conjunction with The International Insolvency Institute – annexed 23 “Global Rules on Conflict-of-Laws Matters in International Insolvency Cases”. These proposed “Global Rules” are intended to “serve as legislative recommendations” to (inter alia) promote uniformity and greater certainty in the unpredictable area of conflict of laws. This article provides a brief commentary upon the 23 proposed Global Rules from an Australian perspective (comparing the effect and intent of each rule with the current Australian conflict-of-laws position) and offers some conclusions as to the merits of the “Global Rules” initiative.

The sequence: Inside the race for the human genome

The human genome project was a grand scientific enterprise which attracted both hyperbole and ridicule alike. The project was lauded as “the moon shot of the life sciences”, the “holy grail of man”, “the code of codes”, and “the book of life”. Such rhetoric has also received scorn. President George Bush senior managed to deflate the pretensions of the project with the accidental slip that it was the “human gnome initiative”. In The Sequence, Kevin Davies seeks to go beyond such metaphors, and provide a candid and honest account of the race of the human genome project. The author is indebted to the authoritative book The Gene Wars, which considered the early struggles over the human genome project. Robert Cook-Deegan observes that there was initially much debate over whether there should be a Human Genome Project at all: The debate became one of “big” science versus “small” science. The reliance on systematic technology development and goal-directed gene-mapping efforts presaged a new style for biology, one that elicited excitement from those attracted to whiz-bang technologies but drew gasps of revulsion from those who aspired to cultivate biology on a more modest scale and with decentralized organisation. The battle was, among other things, over whose vision would control the budget and which scientific aesthetic would prevail.

The Sorcerer II expedition: Intellectual property and biodiscovery

This article considers the significance of a leading marine biodiscovery initiative. In March 2004, Dr. J. Craig Venter announced the official launch of the Sorcerer II Expedition, a scientific expedition of discovery, which would survey marine and terrestrial microbial populations. The Expedition has the potential to uncover tens of thousands of new microbial species and tens of millions of new genes. Venter has disavowed that the Sorcerer II Expedition has any commercial ambitions. However, some have viewed the Sorcerer II Expedition with suspicion. Various civil society groups have accused the Expedition of engaging in 'biopiracy'. This article investigates the Convention on Biological Diversity 1992 and other relevant international treaties, various national and regional regimes to govern access to genetic resources, and benefit-sharing agreements. It considers the intersection of intellectual property law, contract law, environmental law, and international law in this field. This article provides a blueprint for a nationally consistent scheme for access to genetic resources, and a model for future international developments.

The plain truth: Australia, tobacco control, and Southeast Asia

As of December 2012, Australia will be the first country in the world where tobacco products will be sold in olive plain packaging without branding. There has been much discussion as to whether this pioneering initiative will spark an ‘Olive Revolution’ around the world — with other countries adopting the plain packaging of tobacco products. Australia’s neighbours in Southeast Asia would particularly benefit from tobacco control measures such as the plain packaging.
