title: Analytical solutions of fractional diffusion-advection equation for solar cosmic-ray transport

authors: Litvinenko, Yuri E.

abstract: Motivated by recent applications of superdiffusive transport models to shock-accelerated particle distributions in the heliosphere, we analytically solve a one-dimensional fractional diffusion-advection equation for the particle density. We derive an exact Fourier transform solution, simplify it in a weak diffusion approximation, and compare the new solution with previously available analytical results and with a semi-numerical solution based on a Fourier series expansion. We apply the results to the problem of describing the transport of energetic particles, accelerated at a traveling heliospheric shock. Our analysis shows that significant errors may result from assuming an infinite initial distance between the shock and the observer. We argue that the shock travel time should be a parameter of a realistic superdiffusive transport model.

title: Policy for Maori: values, assumptions and closing the gap

authors: Levy, Michelle Patricia

subjects: Maori

abstract: This paper looks at the issue of what it is about the way in which policy is developed which
influences whether or not policy meets the needs of Maori. To do this I will focus on one component
of policy making; the role of the values and assumptions of policy makers. Assumptions about the
nature of policy making and the way in which policy can be used to maintain and modify norms and
standards, determine values and define problems are briefly investigated. These issues are
highlighted using the Code of Family and Social Responsibility as an example of the way in which
dominant cultural value bases and assumptions have influenced the way in which policy issues are
framed and presented. The paper concludes by asking why the consideration of the values of policy
makers is important for Maori and how can I, as a Maori policy analyst working within the
Government policy making sector, contribute to the development of policy which is based on Maori
assumptions, realities, values and world views.
