Understanding Semi-Volatile Pesticides Fate and Transport: Field and Laboratory Studies with Modelling Approach
The use of pesticides in the agricultural sector, alongside other technological advances, caused dramatic increases in crop yield but also accompanying increases in environmental concerns. Pesticide volatilisation and ... -
Viscoelastic finite-difference modelling of gas hydrates in the Pegasus Basin, New Zealand
Gas hydrates are ice-like, solid clathrates that trap natural gas molecules inside a lattice of water molecules. They are common constituents of continental margins, which has led to extensive studies exploring their ... -
Information Package for Users of the New Zealand Estimated Food Costs 2019
Since the 1970s, the Department of Human Nutrition (previously Home Science Extension with the School of Home Science) at the University of Otago has conducted an annual Food Cost Survey. The Food Cost Survey is based on ... -
An Exploration of University Students’ Lived Experience with Alcohol within the Contexts of Family, Peers, and Orientation
Undergraduate students in New Zealand universities demonstrate high rates of hazardous drinking, as do other undergraduates in many universities around the world. There are a number of factors related to hazardous drinking ... -
Does the production value of a short science video hosted on YouTube influence how much the desired audience is likely to enjoy and engage with it?
This thesis continues the research of Welbourne and Grant (2016) within the field of science communication on YouTube, by following the study that Figueiredo, Almeida, & Benevenuto designed to evaluate whether content ... -
New macrocycles for polymerisation catalysis
This thesis concerns the synthesis of diphenylamine-based macrocycles for generating new dimetallic polymerisation catalysts. Chapter 1 introduces the target polymerisations we aim to catalyse, and reviews the current ... -
Hidden Markov Models for Time-Inhomogeneous and Incompletely Observed Point Processes
Many point processes such as earthquakes or volcanic eruptions usually have incomplete records with the degree of incompleteness varying over time. Consequently, hazard estimation from such time-inhomogeneous incomplete ... -
Morphology, phylogeny, and paleoecology of the Kekenodontidae (Mammalia: Cetacea) from the Late Oligocene of New Zealand
The increasingly dense fossil record of archaeocetes (stem cetaceans) is well represented in Eocene strata from the tropics to northern mid-temperate latitudes. Fossils provisionally identified as archaeocetes from Oligocene ... -
The relationship between social reinforcement and performance for individuals with depressive symptoms
Depression is associated with a reduced sensitivity to positive reinforcement. Research suggests this is due to an impaired response to historically rewarding stimuli. However, little experimental research has looked at ... -
Shared factors in autobiographical memory and theory of mind development
When humans use the mental states (e.g., beliefs, intentions) and the emotional states of others to predict or explain another person's behaviour, they have demonstrated their theory of mind understanding. Theory of mind ... -
The effects of the freshwater mussel Hyridella menziesi on the phytoplankton of a shallow Otago lake
Summary 1. Biomass, filtration rate and rhythmic activity data for Hyridella menziesi in Lake Tuakitoto were combined to calculate the filtration capability of this population. It was calculated that this population filters ... -
Improving the Quality of Experience of Over-the-top Video Delivery
The demand for over-the-top (OTT) video delivery (also known as video delivery over the Internet) is increasing rapidly. According to the statistics gathered by Cisco, IP video traffic will be 82% of all global IP traffic ... -
Nesting ecology and behaviour of tuatara (Sphenodon punctatus) at Ōrokonui Ecosanctuary
Understanding the ecology of reproductive behaviours is an essential aspect in studying an animal species. Tuatara (Sphenodon punctatus), once widespread across New Zealand, have become severely restricted in distribution ... -
Marine tourism in New Zealand : environmental issues and options
Tourism is the fastest growing sector of New Zealand's economy and accounts for more than $NZ 3.84 billion in foreign exchange. New Zealand's tourism is based predominantly on scenic attractions, wildlife and natural ... -
He Taoka Kōrerorero The Role of Kāi Tahu Grandparent-Grandchild Communication in Positive Identity Development: A Qualitative Inquiry
Over the last three decades, research into the effects of mother-child reminiscing conversations on children's development has provided a significant insight into how the conversations we have as children impact our ... -
Modification of Catalytically Active and/or Switchable Complexes for Surface Attachment
The overall aim of this project was to take robust complexes which exhibit reversible redox, catalytic activity, or spin crossover (SCO), and design, prepare and characterise suitably functionalised analogues of them, in ... -
Crystal Engineering of Transition Metal Complexes Containing Triple Hydrogen Bond Synthons: Towards the Co-crystallisation of Complexes
The understanding of the structural features within molecular compounds that facilitate their intermolecular assembly by hydrogen bonding, either with themselves or with complementary species, is important for the construction ... -
Collective Effects in Ultra-Cold Dipolar Atom Systems
In this thesis we investigate theoretically two distinct systems of dipole-coupled atoms. In Part I we investigate light scattering from a system of N ultracold atoms, with laser induced electric dipole interactions. We ... -
Lifestyle Factors as Keys to Wellness? Unlocking the Individual, Additive, and Synergistic Associations of Sleep, Diet, and Exercise with Mental Health and Well-Being
Various strategies have been proposed as entry points to promote better mental health and well-being. Among these entry points may be modifiable lifestyle behaviours such as sleep, diet, and exercise. These healthy lifestyle ... -
Hippocampal sharp wave ripple events and place cell activity in a ketamine model of schizophrenia
This experiment aimed to explore the role of hippocampal activity in a pharmacological model of schizophrenia, focusing on hippocampal place cell firing and associated sharp wave ripple events. In a within-subjects design, ...
