title: A Replication of the St. Louis Test for New Zealand

authors: Ng, Ah Kan

abstract: Monetary theory is less abstract than some economic theory in the sense that it cannot avoid a relation to reality. Its development has been to a considerable extent prompted by the experiences encountered by the writers in their own time, and monetary disturbances have always acted as a catalyst in its development. It seems that the role of money in an econmy has appeared to be more important in some periods than others, and writers on monetaryu issues, have therefore, had to adjust their theories accordingly.

title: A mathematical optimisation model of a New Zealand dairy farm: The integrated dairy enterprise (IDEA) framework

authors: Doole, Graeme J.

subjects: dairy production

abstract: Optimisation models are a key tool for the analysis of emerging policies, price sets, and technologies within grazing systems. A detailed nonlinear optimisation model of a New Zealand dairy farming system is described. The framework is notable for its rich portrayal of pasture and cow biology that add substantial descriptive power to standard approaches. Key processes incorporated in the model include: (1) pasture growth and digestibility that differ with residual pasture mass and rotation length, (2) pasture utilisation that varies by stocking rate, and (3) different levels of intake regulation. Model output is shown to closely match data from a more detailed simulation model (deviations between 0 and 5 per cent) and survey data (deviations between 1 and 11 per cent), providing confidence in its predictive capacity. Use of the model is demonstrated in an empirical application investigating the relative profitability of production systems involving different amounts of imported feed under price variation. The case study indicates superior profitability associated with the use of a moderate level of imported supplement, with Operating Profit ($NZ ha-1) of 934, 926, 1186, 1314, and 1093 when imported feed makes up 0, 5, 10, 20 and 30 per cent of the diet, respectively. Stocking rate and milk production per cow increase by 35 and 29 per cent, respectively, as the proportion of imported feed increases from 0 to 30 per cent of the diet. Pasture utilisation increases with stocking rate. Accordingly, pasture eaten and nitrogen fertiliser application increase by 20 and 213 per cent, respectively, as the proportion of imported feed increases from 0 to 30 per cent of the diet.

title: Ki te kapu o taku ringa - In the palm of my hand [Photography exhibition at Gallagher Academy of Performing Arts]

authors: Hill, Rodrigo

subjects: Mātauranga Māori

abstract: (Exhibition catalogue)
The title Ki te kapu o taku ringa is taken from a line of
‘Maioha mō Waikato’ by Kīngi Tāwhiao. Ejected from their
homelands he and his Waikato brethren took refuge with
their Maniapoto relations in Te Nehenehenui. The maioha
was composed expressing Kīngi Tāwhiao’s love for his
homelands, and his solastalgic holding fast to those lands
‘... in the palm of his hand.’ The words from the song-poem
were used as guide to our research and photography practice.
