title: Investigating the relationships between the yield curve, output and inflation using an arbitrage-free version of the Nelson and Siegel class of yield curve models

authors: Krippner, Leo

subjects: yield curve

abstract: This article provides a theoretical economic foundation for the popular Nelson and Siegel (1987) class of yield curve models (which has been absent up to now). This foundation also offers a new framework for investigating and interpreting the relationships between the yield curve, output and inflation that have already been well-established empirically in the literature. Specifically, the level of the yield curve as measured by the VAO model is predicted to have a cointegrating relationship with inflation, and the shape of the yield curve as measured by the VAO model is predicted to correspond to the profile (that is, timing and magnitude) of future changes in the output gap (that is, output growth less the growth in potential output). These relationships are confirmed in the empirical analysis on 50 years of United States data.

title: Hidden Terminal Detection in Wide-Area 802.11 Wireless Networks

authors: Raynel, Scott McKenzie

subjects: hidden terminals

abstract: The hidden terminal problem is an important issue in wireless networks based on the CSMA medium access control scheme. Hidden terminals pose a complex challenge to network operators trying to identify the underlying cause of performance issues.
This thesis describes new methods for the detection and measurement of the hidden terminal problem in wireless networks based on commodity hardware and software platforms. These new methods allow network operators to identify areas of a network where hidden terminals are likely to exist; detect instances of the hidden terminal problem occurring; and estimate the total impact hidden terminals are having on the performance of the network.
A new framework for measurement of wireless networks is described which provides a new approach to wireless measurement on Linux based wireless routers. The new framework is used to implement the methods and they are deployed across an operational commercial wireless network and are shown to be useful.

title: A Way Forward for Te Reo Maori in English-Medium Education

authors: Waikari, Arihia

subjects: Maori

abstract: Aotearoa is the home of the Māori people and their language; te reo Māori. When European settlers arrived, they brought with them a new language; English. The Treaty of Waitangi was signed in 1840 and guaranteed Māori rangatiratanga (chiefly control) over their taonga, including te reo Māori. Over the years a negative language shift has occurred with many Māori moving from speaking te reo Māori to English. Although many initiatives, such as kōhanga reo were implemented in the 1980s, te reo Māori is still in a critical state. This research project is about te reo Māori experiences of both Māori and non-Māori whom were all attached to a English-medium primary school in Aotearoa/New Zealand. This study sought to understand the ways in which te reo Māori was being passed on, or not, from person to person and from one generation to the next.
