    The importance of understanding Indigenous employment in the Indigenous business sector

    Get PDF
    Indigenous employment has been the subject of numerous policies in Australia, with governments aiming to increase the workforce participation rate amongst Indigenous people in recent years. Indigenous-owned businesses, formally defined as businesses that are at least 50% Indigenous-owned, have been demonstrated in previous research to maintain substantially higher levels of proportional Indigenous employment than non-Indigenous businesses. This suggests that Indigenous-owned businesses maintain work environments that are more supportive of and conducive to Indigenous employment, meriting the influence of Indigenous-owned businesses' workplace practices in future Indigenous employment policy design. Using administrative data from two Indigenous business registries (Black Business Finder and Supply Nation), this paper provides an updated empirical analysis of the Indigenous business sector. This paper demonstrates that Indigenous-owned businesses of all sizes, industries, locations and profit statuses consistently average proportional Indigenous employment rates higher than the Indigenous proportional population. Of all the people employed in Supply Nation-listed businesses, over 35% are Indigenous. The potential impact of the Indigenous Procurement Policy is illustrated by differentials in the size of businesses and their capacity to employ Indigenous staff. This paper provides analysis of the Indigenous business sector that can inform future policy direction for both Indigenous employment and Indigenous business policies. © 2023 The Authors.

    An Overview of Legal Instruments and Other Measures to Aid in the Protection and Valuation of Indigenous Knowledge

    Get PDF
    This paper outlines the legal instruments and other measures used to support the protection of Indigenous Knowledge (IK), with a view to attributing market value to IK. These instruments are categorised as either enforceable instruments or voluntary protocols, standards and guides. Enforceable instruments have a clear connection to market value, typically being tradeable with a cost incurred to protect their attributable IK. While legal costs, patent prices and licence fees are private, it may be possible to gain access to summarised and de-identified data. Non-enforceable rights such as protocols, codes of conduct and certification may involve compensation or payments designed to protect IK. Price premiums may help to capture the market value of attributable IK, but require careful methodological consideration. A diverse range of instruments helps to provide choice to Indigenous Peoples and creates a system that may support the development of social and market norms that encourage the recognition and protection of IK

    Study protocol for Running for health (Run4Health CP) : a multicentre, assessor-blinded randomised controlled trial of 12 weeks of two times weekly Frame Running training versus usual care to improve cardiovascular health risk factors in children and youth with cerebral palsy

    Get PDF
    Introduction: Children and youth with moderate-severe (Gross Motor Function Classification System (GMFCS) levels II–V) cerebral palsy (CP) participate less frequently in physical activities compared with peers without CP and have elevated risk of cardiorespiratory morbidity and mortality in adulthood. Frame Running (RaceRunning) is a new athletics discipline that is an accessible option for physical activity participation for people with moderate-severe CP. There is no high-quality evidence for the effect of Frame Running on cardiovascular disease in children and young people with CP. The primary aim of this study is to conduct a randomised controlled trial of the effect of 12 weeks of Frame Running training on risk factors for cardiovascular disease. Methods and analysis: Sixty-two children and youth with CP (age 8–20 years) in GMFCS levels II–V will be recruited across four sites and randomised to receive either 12 weeks of Frame Running training two times weekly for 60 min, or usual care. Outcomes will be measured at baseline, immediately postintervention (primary endpoint) and 12 weeks later for retention of training effects. The primary outcome is cardiorespiratory fitness as measured by distance covered on Six Minute RaceRunner Test with 1 min heart rate recovery. Other outcomes include blood pressure, objectively measured physical activity, body mass index, waist circumference, percentage body fat, gross motor function capacity, community participation, feasibility, tolerability and safety. Adverse events will be monitored, and participants and their caregivers will be interviewed to discern their experiences of participation in Frame Running. Ethics and dissemination: The Children’s Health Queensland Hospital and Health Service and the University of Queensland Human Research Ethics Committees have approved this study. Results will be disseminated in peer-reviewed journals and scientific conferences; through professional and athletic organisations; and to people with CP and their families.

    Marine Phytoplankton Temperature versus Growth Responses from Polar to Tropical Waters – Outcome of a Scientific Community-Wide Study

    "It takes a village to finish (marine) science these days" Paraphrased from Curtis Huttenhower (the Human Microbiome project) The rapidity and complexity of climate change and its potential effects on ocean biota are challenging how ocean scientists conduct research. One way in which we can begin to better tackle these challenges is to conduct community-wide scientific studies. This study provides physiological datasets fundamental to understanding functional responses of phytoplankton growth rates to temperature. While physiological experiments are not new, our experiments were conducted in many laboratories using agreed upon protocols and 25 strains of eukaryotic and prokaryotic phytoplankton isolated across a wide range of marine environments from polar to tropical, and from nearshore waters to the open ocean. This community-wide approach provides both comprehensive and internally consistent datasets produced over considerably shorter time scales than conventional individual and often uncoordinated lab efforts. Such datasets can be used to parameterise global ocean model projections of environmental change and to provide initial insights into the magnitude of regional biogeographic change in ocean biota in the coming decades. Here, we compare our datasets with a compilation of literature data on phytoplankton growth responses to temperature. A comparison with prior published data suggests that the optimal temperatures of individual species and, to a lesser degree, thermal niches were similar across studies. However, a comparison of the maximum growth rate across studies revealed significant departures between this and previously collected datasets, which may be due to differences in the cultured isolates, temporal changes in the clonal isolates in cultures, and/or differences in culture conditions. Such methodological differences mean that using particular trait measurements from the prior literature might introduce unknown errors and bias into modelling projections. Using our community-wide approach we can reduce such protocol-driven variability in culture studies, and can begin to address more complex issues such as the effect of multiple environmental drivers on ocean biota.EL and MKT were in part supported by the National Science Foundation (NSF) grants DEB-0845932 and OCE-0928819.

    The discovery of potent, selective, and reversible inhibitors of the house dust mite peptidase allergen Der p 1: an innovative approach to the treatment of allergic asthma.

    Get PDF
    Blocking the bioactivity of allergens is conceptually attractive as a small-molecule therapy for allergic diseases but has not been attempted previously. Group 1 allergens of house dust mites (HDM) are meaningful targets in this quest because they are globally prevalent and clinically important triggers of allergic asthma. Group 1 HDM allergens are cysteine peptidases whose proteolytic activity triggers essential steps in the allergy cascade. Using the HDM allergen Der p 1 as an archetype for structure-based drug discovery, we have identified a series of novel, reversible inhibitors. Potency and selectivity were manipulated by optimizing drug interactions with enzyme binding pockets, while variation of terminal groups conferred the physicochemical and pharmacokinetic attributes required for inhaled delivery. Studies in animals challenged with the gamut of HDM allergens showed an attenuation of allergic responses by targeting just a single component, namely, Der p 1. Our findings suggest that these inhibitors may be used as novel therapies for allergic asthma

    NACHOS, a CubeSat-Based High-Resolution UV-Visible Hyperspectral Imager for Remote Sensing of Trace Gases: System Overview, Science Objectives, and Preliminary Results

    Get PDF
    The Nano-satellite Atmospheric Chemistry Hyperspectral Observation System (NACHOS) is a high-throughput (f/2.9), high spectral resolution (1.3 nm optical, 0.57 nm sampling) hyperspectral imager covering the 300-500 nm spectral region with 350 spectral bands. The combined 1.5U instrument payload and 1.5U spacecraft bus comprise a 3U CubeSat. Spectroscopically similar to NASA’s Ozone Monitoring Instrument (OMI), which provides wide-field coverage at ~20 km spatial resolution, NACHOS offers complementary targeted measurements at far higher spatial resolution of ~0.4 km/pixel from 500 km altitude over its 15 ̊ across-track field of view. NACHOS incorporates highly streamlined onboard gas-retrieval algorithms, alleviating the need to routinely downlink massive hyperspectral data cubes. This paper discusses the instrument design, requirements leading to it, preliminary results, and science goals, including monitoring NO2 as a proxy for anthropogenic greenhouse gases, low-level degassing of SO2 and halogen oxides at pre-eruptive volcanoes, and formaldehyde from wildfires. Aiming for an eventual many-satellite constellation providing both high spatial resolution and frequent target revisits, the current NACHOS project is launching two CubeSats, the first already launched to the International Space Station aboard the NG-17 Cygnus vehicle on February 19, 2022 and awaiting deployment to its final orbit in June, and the second launching June 29, 2022
