In Australia and New Zealand (NZ) domestic wood heater emissions contribute to a substantial community burden of air pollution-related illness and death. Despite increasingly stringent emission standards for wood heaters in Australia, there has been frustratingly little progress in reducing ambient air pollution from this source. In contrast, Environment Canterbury NZ, has made impressive progress driving innovation in wood heater designs to improve air quality. Interventions have included the 2014 introduction of a new performance testing standard, the Canterbury Method One (CM1) that is used to define a class of Ultra Low Emission Burners (ULEBs). CM1 testing is conducted under conditions intended to simulate typical home usage and includes the heater's start-up phase which generates a significant portion of pollutant emissions. It is primarily designed to test the performance of appliances burning softwoods, the main source of fuel in NZ. We aimed to: (1) design a protocol based on the CM1 for testing appliances burning Australian hardwoods, and (2) conduct preliminary evaluations of exiting ULEBs fuelled with hardwoods as a test-of-concept for ULEBs in Australia. The main variation was that we used a single burn phase with double the weight of wood compared with the standard CM1. We tested two certified ULEBs of different designs using our protocol. Emissions from hardwood fuels were higher than for softwoods as anticipated because the appliances we tested had been optimised for softwood combustion. However, the overall performance of both heaters was promising. Our results provide proof-ofconcept that ULEBs could potentially be optimised for hardwoods and have a place in strategies for reducing the harm from air pollution in Australia.

Proponents of development projects (e.g., new roads, mines, dams) are frequently required to assess and manage their impacts on threatened biodiversity. Here, we propose that the environmental legislation and standards that mandate such assessments are failing those threatened species and ecological communities listed as vulnerable. Using a case study of Australia's key environmental legislation, we highlight that vulnerable ecological communities receive no statutory protection, while vulnerable species are held to a less stringent standard in the impact assessment process compared with those that are endangered or critically endangered. In the 19 years since Australia's Environment Protection and Biodiversity Conservation Act 1999 was enacted, four times as many vulnerable species have declined in their threat status than have improved. Beyond Australia, we demonstrate the global relevance of this issue, as it applies to internationally recognized best practice impact assessment guidelines. These cases provide a cautionary tale: without greater attention and stricter assessment criteria in the impact assessment process, the vulnerable species of today risk becoming the endangered species of tomorrow, with all the attendant costs and missed opportunities for recovery that this implies.

Many governments in Western democracies conduct the work of leading their societies forward through policy generation and implementation. Despite government attempts at extensive negotiation, collaboration and debate, the general populace in these same countries frequently express feelings of disempowerment and undue pressure to be compliant, often leading to disengagement. Here we outline Plan B: a process for examining how policies that emerge from good intentions are frequently interpreted as burdensome or irrelevant by those on whom they have an impact. Using a case study of professional standards for teachers in Australia, we describe how we distilled Foucault's notions of archaeology into a research approach centring on the creation of ‘polyhedrons of intelligibility’ as an alternative approach by which both policy-makers and those affected by their policies may understand how their respective causes are supported and adversely affected.

Objectives: The authors outline the difference between content and performance standards and the rationale for standard setting at a medical college. The principles of the college's standard setting processes for the written and objective structured clinical examination summative assessments are discussed in greater detail.Conclusion: There is no evidence of any single standard setting method to be the best. Multiple methods exist and will have varied results when applied. The judgement of a panel of subject experts remains an important component of the standard setting process. [ABSTRACT FROM AUTHOR]

Extensive efforts are currently being devoted to the establishment of soil spectral libraries on regional, national, continent-wide and global domains. In particular, a new development goes in the direction of global harmonized soil spectral databases that shall be acquired following common standards and procedures so that they can be merged with other soil spectral libraries. The choice of standards is important, especially with respect to their behaviors when laboratory conditions, such as humidity, change. In this study, we test the application and robustness of the Internal Soil Standard (ISS) spectral re-alignment procedure on an extended number of soil samples acquired at different laboratories. In particular, a focus is placed on the comparison between two standards Lucky Bay (LB) and Wylie Bay (WB), for their performance with different humidity laboratory conditions. LB and WB are almost pure quartz sands from Australia. For this, 71 soil samples from Israel with different mineralogical background and variable soil organic matter contents are scanned at two laboratories. The scanning took place with different spectral measurement protocols and extreme diverse conditions in terms of laboratory humidity and moist. All scans are completed by the repeated scans of the two Australian white sands through all scan batches to harmonize the spectral measurements. Our results show that the ISS minimizes the visual spectral variation, aligns the minor and extreme systematic changes of the protocols, and makes them more stable. Furthermore, the LB and WB standards do not exhibit equal performance regarding to relatively dry and humid conditions. The WB standard provides more stable and satisfactory results in humid condition. However, the high performance of the LB sample in spectral correction is still observed, particularly in laboratories with lower moist. Accordingly, these analyses suggest that in the ISS re-alignment procedure, the WB sample is more reliable to be used in humid laboratory condition. • Testing the ISS method for spectral harmonization of a large number of soil spectra acquired in different laboratories • Testing the effects of different setups and extreme different laboratory humidity conditions • Comparing the performances of two standards LB and WB in the ISS re-alignment procedure • WB is recommended to be used in laboratories with high moist condition [ABSTRACT FROM AUTHOR]
