title: Lake models – fact sheet

authors: Hamilton, David P.

abstract: Models of lakes are used to provide insights into water quality at some future point in time, so that management actions may be targeted and cost-effective. In the past, small-scale physical models were used to simulate lake environments (Figure 1), but nowadays computer models are used to test potential management options. Computer models use a series of mathematical equations to describe the complex interactions amongst physical, chemical and biological processes that affect the water quality of a lake. The equations are stitched together consecutively in a computer program, allowing millions of calculations to take place in a single simulation.

title: Metadata and organizational structures in personal photograph digital libraries

authors: Cunningham, Sally Jo

subjects: computer science

abstract: We examine the ‘native’ metadata and organizational structures that individuals create for their personal photo digital libraries, by analyzing the behaviour of photo collectors as recorded in 37 autoethnographies and ethnographies. The findings confirm several common assumptions about how people organize their photos that have been the basis for features in earlier photo digital libraries- that photos are commonly organized by time, event, and location, and that collection owners create very little metadata manually. We discuss alternate sources of metadata that arise as a consequence of sharing photos, and consider additional features for photo digital libraries that may be useful in supporting searching and browsing of personal collections.

title: Keepa Te Wharau: a Ngati Rahiri rangatira

authors: Hart, Philip

abstract: Keepa Te Wharau’s whakapapa linked him, unusually, to both Ngati Maru and Ngati Haua. Through these connections he was associated with the Te Aroha district from an early age, visiting it on several occasions and even cultivating there, briefly. When the block was before the land court he gave evidence – though his evidence in a later succession case was clearly wrong, deliberately so. Having interests in several blocks of land, he falsely claimed not to have received money for the Aroha Block, using the excuse of drunkenness, for which he was before the court on several occasions. He would sell land, as would his children, to meet living expenses. He invested in two goldfields, Thames and Te Aroha, very modestly. A leading rangatira, he was notable for his loyalty to the Crown.
