title: Guarded operations, refinement and simulation

authors: Reeves, Steve

subjects: computer science

abstract: Simulation rules have long been used as an effective computational means to decide refinement relations in state-based formalisms. Here we investigate how they might be amended so as to decide the event-based notion of singleton failures refinement of abstract data types, or processes, that have operations with a “guarded” interpretation.

title: Using Engel curves to measure CPI bias for Indonesia

authors: Olivia, Susan

subjects: CPI bias

abstract: To measure real income growth over time a price index is needed to adjust for changes in the cost of living. The Consumer Price Index (CPI) is often used for this task but studies from several countries show the CPI is a biased measure of changes in the cost of living, leading to potentially wrong estimates of the rate of growth of real income. In this paper CPI bias for Indonesia is calculated by estimating food Engel curves for households with the same level of CPI-deflated incomes at four different points in time between 1993 and 2008. The results suggest CPI bias was initially negative during the Asian Crisis but has been positive since 2000. Over the entire period, CPI bias has averaged four percent annually, equivalent to almost one-third of the measured inflation rate.

title: Te Ika Huirua o Te Mate

authors: Maxwell, Te Kahautu

abstract: This composition is a lament to two staesman of the Māori world Apira Mahuika of Ngāti Porou and Tama Huata of Ngāti Kahungunu. Both men were giants in their respective areas, governance, tribal politics cultral revival language revitalisation, Treaty settlements they both died within days of each other. This compostion also talks about how Pākeha law clashes with Māori lore with the James Takamore case where his whanau took his body and returned it to James ancestral home Whakatohea and the widow laid charges to have her husbands remains dug up and returned to Christchuch. I thought it appropriate to protest about this being the Te Matatini World Championship Kapa Haka Competition was held in Christchurch March 2015. This composition was performed by Ōpōtiki Mai Tawhiti.
