Textual query languages based on Boolean logic are common amongst the search facilities of on-line information repositories. However, there is evidence to suggest that the syntactic and semantic demands of such languages lead to user errors and adversely affect the time that it takes users to form queries. Additionally, users are faced with user interfaces to these repositories which are... [Working or Discussion Paper]

Vacuum field emission devices have become a promising candidate for emerging display technology due to their interesting properties compared to conventional thermionic emission devices that require high temperature and power to operate. Unlike thermionic emission, field emission devices can induce the electrons to emit at low temperature; sharp and thin emitters on the cathode are desired in...

Previously published items are reproduced in accordance with the copyright policy of the publisher.Semistructured data is typically represented using XML. However, little semantic information can be captured using XML. Other data models, such as the object relationship attribute data model for semistructured data (ORA-SS), have been introduced to represent more detailed semantic information. Automatic analysis of the data models would enable us to reveal inconsistencies both at the schema... [Conference Paper]

This thesis covers a variety of analytical approaches that validate the use of the EvacuatioNZ model on high-rise building analysis. Through performing a number of sensitivity analyses, several model deficiencies as well as functional limitations were improved upon and part of the model developments are continued based on the previous research done by two Master's students at the...

The accuracy of the Lagrangian approach for predicting droplet trajectories and evaporation rates within a simple spray has been addressed. The turbulent dispersion and overall evaporation rates of droplets are modeled reasonably well, although the downstream velocity decay of the larger droplets is underpredicted, which is attributed to a poor estimate of the radial fluctuating velocity of...

Both marketing researchers and practitioners realise that having customer relationships that enhance a firm's competitive advantage is an important strategic issue and that there is a need for relationship value measurement. But the research on relationship value measurement is limited, especially from a seller's perspective, despite numerous calls for it. The reason for the limited... [Thesis or Dissertation]

The recent move to in situ conservation management world-wide is supported by, and stems from the 1992 International Convention on Biological Diversity. The Department of Conservation - charged with the conservation of New Zealand's natural resources - has directed efforts towards the restoration of natural processes as an avenue to halt local biodiversity decline. Ecosystem, habitat, and...

The Brown ADD Scale for Adolescents is used widely clinically yet no published studies have investigated divergent and concurrent validity, specificity and sensitivity to inattentive ADHD symptomatology. Ninety-eight participants (13 to 16 years) were classified as ADHD/I and/or reading disabled (RD) using K-SADS, Conners Rating Scales (CRS-R) and Ontario Child Health Study Scales (OCHSS),...

We investigate the value relevance of the financial statement information about convertible financial instruments. Our findings indicate that the classification of convertibles provides incremental information over and above the book value of equity and net income. This finding is not as strong for convertibles that are classified as a form of mezzanine financing between debt and equity as for...

Australian public sector reforms have emphasised the accountability of agencies for the performance of management. Despite considerable diversity in public sector organisations, annual reports have been promoted as an appropriate tool to discharge the accountability of all government agencies. However, there remains an absence of consistent empirical evidence as to the value of the annual...

This study examines the empirical relationship between the price-to-earnings (P/E) ratio and returns on the common stock of NZSE firms. The results show a substantial difference in raw returns between low P/E and high P/E stocks, and between negative earnings and high P/E stocks. However, once returns are adjusted for risk, using both the Capital Asset Pricing Model and the alternative model... [Thesis or Dissertation]

The fragility of the CAPM has led to a resurgence of research that frequently uses trading strategies based on sorting procedures to uncover relations between firm characteristics (such as “value” or “glamour”) and equity returns. We examine the propensity of these strategies to generate statistically and economically significant profits due to our familiarity with the data. Under... [Conference Item]

Paper presented at the 51st Annual Conference of the Australian Agricultural and Resource Economics Society, Queenstown, New Zealand, 13-16 February, 2007.The increase in greenhouse gas emissions and degradation of water quality and quantity in waterways due to dairy farming in New Zealand have become of growing concern. Compared to traditional sheep and beef cattle farming, dairy farming is more input intensive and more likely to cause such environmental damage. Our study uses choice modeling to explore New Zealanders ' willingness to pay... [Conference Paper]

Restricted Item. Print thesis available in the University of Auckland Library or available through Inter-Library Loan. Porous Titania Glass (PTG) is a novel meso-porous form of TiO2, which can have a surface area as high as 300 m2 g-1, depending on thermal pretreatment. Such high surface areas have given PTG the potential to be a better catalytic support than other forms of titania for many... [Thesis or Dissertation]

Restricted Item. Print thesis available in the University of Auckland Library or available through Inter-Library Loan. Vanilla is becoming an increasingly important crop in the South Pacific. Two different vanilla potyviruses infect the two commercial vanilla species grown in the region, Vanilla fragrans, which is grown mainly in Tonga, Cook Islands, Fiji and Vanuatu, is infected by vanilla...

In 1998/99 and 1999/2000, field trials were conducted to try to explain why grain legume yields and harvest index are more variable than many other crops. Treatments involved varying plant populations and sowing depths and were selected to maximize plant variability. Both yields and harvest index were variable. Total dry matter (TDM) production generally increased as plant population increased... [Journal Article]

The effects of plant population (one-tenth of the optimum to four times the optimum populations in 1998/99 and 10–400 plants/m² in 1999/2000) and sowing depth (2, 5 and 10 cm) on yield and yield components of four grain-legumes (Cicer arietinum, Lens culinaris, Lupinus angustifolius and Pisum sativum) were studied. Seed yields were strongly positively correlated with the number of pods and... [Journal Article]

Previously published items are reproduced in accordance with the copyright policy of the publisher.A practical dynamic inductor-tuning circuit for a parallel resonant ICPT power pickup operating at 38.4kHz is described. The method controls the current through a tuning inductor by varying the turn on delay of two power switches. This varies the inductor current so that the tank may be maintained at resonance. Supporting mathematical analysis, circuit simulation and prototype measurements are... [Conference Paper]

Pigeons were studied in concurrent chain schedules in which the terminal links were variable-interval (aperiodic) and fixed-interval (periodic) schedules. Choice was studied at various maintained percentages of body weight, (Experiment 1) and after various amounts of food had been pre-fed (Experiment 2). No effects on choice of the level of deprivation were found except in those choice... [Thesis or Dissertation]

Variance components were estimated using alternative structures for the additive genetic covariance matrix (G₀), for height (m) of trees measured at 10 unequally spaced ages in an open-pollinated progeny test. These structures reflected unstructured, autoregressive, banded correlation and random regressions models. The residual matrix (R₀) was unstructured, and the block and plot strata...

Variation in advertisement call structure of whistling frogs, Litoria ewingi, was studied among breeding sites in the vicinity of Christchurch on the East coast and Harihari on the West coast of the South Island. Males vocalized in breeding choruses throughout the year and females moved toward and appeared to evaluate calls of territorial males before initiating amplexus. Acoustic interactions...
