title: The New Zealand public’s readiness for connected- and autonomous-vehicles (including driverless), car and ridesharing schemes and the social impacts of these

authors: Starkey, Nicola J.

subjects: attitudes

abstract: The NZ Transport Agency is a Crown entity established under the Land Transport Management Act 2003. The objective of the Agency is to undertake its functions in a way that contributes to an efficient, effective and safe land transport system in the public interest. Each year, the NZ Transport Agency funds innovative and relevant research that contributes to this objective.
The views expressed in research reports are the outcomes of the independent research, and should not be regarded as being the opinion or responsibility of the NZ Transport Agency. The material contained in the reports should not be construed in any way as policy adopted by the NZ Transport Agency or indeed any agency of the NZ Government. The reports may, however, be used by NZ Government agencies as a reference in the development of policy.
While research reports are believed to be correct at the time of their preparation, the NZ Transport Agency and agents involved in their preparation and publication do not accept any liability for use of the research. People using the research, whether directly or indirectly, should apply and rely on their own skill and judgement. They should not rely on the contents of the research reports in isolation from other sources of advice and information. If necessary, they should seek appropriate legal or other expert advice

title: Modelling water, sediment and nutrient fluxes from a mixed land-use catchment in New Zealand: effects of hydrologic conditions on SWAT model performance

authors: Me, W.

abstract: The Soil Water Assessment Tool (SWAT) was configured for the Puarenga Stream catchment (77 km2), Rotorua, New Zealand. The catchment land use is mostly plantation forest, some of which is spray-irrigated with treated wastewater. A Sequential Uncertainty Fitting (SUFI-2) procedure was used to auto-calibrate unknown parameter values in the SWAT model which was applied to the Puarenga catchment. Discharge, sediment, and nutrient variables were then partitioned into two components (base flow and quick flow) based on hydrograph separation. A manual procedure (one-at a-time sensitivity analysis) was then used to quantify parameter sensitivity for the two hydrologically-separated regimes. Comparison of simulated daily mean discharge, sediment and nutrient concentrations with high-frequency, event-based measurements allowed the error in model predictions to be quantified. This comparison highlighted the potential for model error associated with quick-flow fluxes in flashy lower-order streams to be underestimated compared with low-frequency (e.g. monthly) measurements derived predominantly from base flow measurements. To overcome this problem we advocate the use of high-frequency, event-based monitoring data during calibration and dynamic parameter values with some dependence on discharge regime. This study has important implications for quantifying uncertainty in hydrological models, particularly for studies where model simulations are used to simulate responses of stream discharge and composition to changes in irrigation and land management.

title: Dialogue as a method for evolving Mātauranga Māori: Perspectives on the use of embryos in research

authors: Hudson, Maui

subjects: New Zealand

abstract: This paper explores the epistemological divide between mātauranga Māori (Māori knowledge) and science, and considers which cultural concepts have relevance when considering the use of embryos in research. We argue that empowerment is a necessary precursor for a dialogue process to be effective and to maintain the cultural dignity and confidence of the participants. Negotiating spaces to share ideas, concepts and values between different knowledge systems is an important exercise that creates opportunities for innovative thinking. The identification of cultural cues and indigenous reference points for considering how knowledge relating to embryo research might be located within a traditional knowledge schema is a necessary type of activity to ensure mātauranga Māori maintains its usefulness for Māori in a changing society while retaining its indigenous spirit and cultural tradition.
