The Dynamics Of Dense Water Cascades: From Laboratory Scales To The Arctic Ocean, Fred Wobus Jan 2013

The Dynamics Of Dense Water Cascades: From Laboratory Scales To The Arctic Ocean, Fred Wobus

Other Faculty of Science and Engineering Theses

The sinking of dense shelf waters down the continental slope (or “cascading”) contributes to oceanic water mass formation and carbon cycling. Cascading is therefore of significant importance for the global overturning circulation and thus climate. The occurrence of cascades is highly intermittent in space and time and observations of the process itself (rather than its outcomes) are scarce. Global climate models do not typically resolve cascading owing to numerical challenges concerning turbulence, mixing and faithful representation of bottom boundary layer dynamics. This work was motivated by the need to improve the representation of cascading in numerical ocean circulation models. Typical …

Allelopathic Potential Of The Invasive Alien Himalayan Balsam (Impatiens Glandulifera Royle), Owen Peter Smith

Other Faculty of Science and Engineering Theses

Investigations were carried out into the allelopathic potential of the invasive alien annual Himalayan Balsam (Impatiens glandulifera Royle) using a series of bioassays, including ones developed or adapted for this study. They were evaluated for their suitability to detect three of the four main modes of allelochemical release, namely leaching, exudation and decomposition. Assays which involved the measurement of lettuce radicles and hypocotyls gave reliable results and allowed a range of different Impatiens material, both living and dead, to be assessed and ranked according to the allelopathic effects demonstrated. Attempts were made to isolate resource competition from allelopathy using separately …

Histopathological Effects Of Metal And Metalic Nanoparticles On The Body Systems Of Rainbow Trout (Oncorhynchus Mykiss), Genan Adnan Al-Bairuty Jan 2013

Histopathological Effects Of Metal And Metalic Nanoparticles On The Body Systems Of Rainbow Trout (Oncorhynchus Mykiss), Genan Adnan Al-Bairuty

Other Faculty of Science and Engineering Theses

Histopathology studies of metal nanoparticles (NPs) compared to traditional forms of metal in fish are scarce. Additionally, it is unclear whether metal nanoparticles cause greater or different pathologies compared to other forms of metal. The current study aimed to assess the pathological effects of Cu-NPs and TiO2 NPs on rainbow trout via various routes of exposure and, where appropriate, to compare them to either the equivalent dissolved metal salts or bulk powder forms. The first experiment showed that waterborne exposure to Cu-NPs and CuSO4 caused similar types of organ pathologies and alteration in the spleen content, however there were some …

A Comparison Of Carbon Sequestration Potential And Photosynthetic Efficiency In Evergreen And Deciduous Oaks Growing In Contrasting Environments In The Southwest Uk, Demelza Carne Jan 2013

A Comparison Of Carbon Sequestration Potential And Photosynthetic Efficiency In Evergreen And Deciduous Oaks Growing In Contrasting Environments In The Southwest Uk, Demelza Carne

Other Faculty of Science and Engineering Theses

Global climate change is predicted to alter the weather patterns around the world, as climatic zones shift, forest carbon sequestration projects (e.g. the UK woodland carbon code) need to take into account the specific requirements of planted species. In the UK, oaks are an important charismatic group of trees favoured in recent planting programmes. The English oak (Quercus robur L.), has poor water conservation, but is a major component of natural forests in lowland UK. On the other hand, Holm oak (Quercus ilex L.) is a Mediterranean oak that has high water conservation and can also tolerate cold despite being …

Rule Based Forecasting [Rbf] - Improving Efficacy Of Judgmental Forecasts Using Simplified Expert Rules, Monica Adya, Edward J. Lusk Jan 2013

Rule Based Forecasting [Rbf] - Improving Efficacy Of Judgmental Forecasts Using Simplified Expert Rules, Monica Adya, Edward J. Lusk

Management Faculty Research and Publications

Rule-based Forecasting (RBF) has emerged to be an effective forecasting model compared to well-accepted benchmarks. However, the original RBF model, introduced in1992, incorporates 99 production rules and is, therefore, difficult to apply judgmentally. In this research study, we present a core rule-set from RBF that can be used to inform both judgmental forecasting practice and pedagogy. The simplified rule-set, called coreRBF, is validated by asking forecasters to judgmentally apply the rules to time series forecasting tasks. Results demonstrate that forecasting accuracy from judgmental use of coreRBF is not statistically different from that reported from similar applications of RBF. Further, we …

The Case Of Microsoft's Surface Tablet: Going Behind The Strategy With Swot, David R. King, Todd Peterson Jan 2013

The Case Of Microsoft's Surface Tablet: Going Behind The Strategy With Swot, David R. King, Todd Peterson

Management Faculty Research and Publications

Following its development at Harvard Business School in the 1950s, the SWOT framework became a frequently used decision tool. While the complexity organizations confront in the modern business world has increased, SWOT provides an intuitive way to organize information into internal “Strengths and Weaknesses” and external “Opportunities and Threats.” Another reason that SWOT remains relevant is its flexibility that enables integrating other analysis tools. It also encompasses multiple steps of strategy development to cover analysis, formulating options, and implementation.

Bodies, Emotions And Tourism: A Study Of Costa Cruises Commercials, Mariangela Albano, Gaetano Sabato Jan 2013

Bodies, Emotions And Tourism: A Study Of Costa Cruises Commercials, Mariangela Albano, Gaetano Sabato

Journal of Tourism Consumption and Practice

Nowadays, tourism industry proposes different opportunities to live a vacation where the body is the main interest and the central focus of experience. Each form of tourism shows a particular universe of representation of the body and a corresponding emotional language. In this context, where bodies and spaces are associated and reciprocally constructed as symbolic languages for the benefit of the tourist’s extraordinary experience, cruise tourism is an interesting case in point to analyze above all because on cruises, people use the space of the ship in different ways and, at the same time, following general corporeal and spatial schemes. …

The Muslim Sports Tourist And The Olympic Games Movement, Karl A. Russell, Noëlle O'Connor Jan 2013

The Muslim Sports Tourist And The Olympic Games Movement, Karl A. Russell, Noëlle O'Connor

Journal of Tourism Consumption and Practice

This paper explores the view that the Olympic Games Movement and the modern day Olympic Games while seeking to be a secular event is regarded by many participants and spectators as an event where they are able to demonstrate expressions of their religious faith. The first Olympic Games were staged in ancient Greece and they comprised a series of sporting events staged as a way of honouring the Greek God; Zeus, considered by the Romans to be a pagan god. The origins and mythology surrounding the early Olympic Games had a non-secular basis and led to an almost intrinsic belief …

Learning, Self-Organisation And Homeostasis In Spiking Neuron Networks Using Spike-Timing Dependent Plasticity, James Humble Jan 2013

Learning, Self-Organisation And Homeostasis In Spiking Neuron Networks Using Spike-Timing Dependent Plasticity, James Humble

Other Faculty of Science and Engineering Theses

Spike-timing dependent plasticity is a learning mechanism used extensively within neural modelling. The learning rule has been shown to allow a neuron to find the onset of a spatio-temporal pattern repeated among its afferents. In this thesis, the first question addressed is ‘what does this neuron learn?’ With a spiking neuron model and linear prediction, evidence is adduced that the neuron learns two components: (1) the level of average background activity and (2) specific spike times of a pattern. Taking advantage of these findings, a network is developed that can train recognisers for longer spatio-temporal input signals using spike-timing dependent …

Mood, Emotive Content, And Reasoning, Daniel Zahra Jan 2013

Mood, Emotive Content, And Reasoning, Daniel Zahra

Other Faculty of Science and Engineering Theses

Mood, Emotive Content, and Reasoning - Daniel Zahra Theories of how individuals reason, and how they experience emotion abound in the psychological literature; yet, despite the common lay-theories of how emotions might affect a person’s reasoning, very little empirical work has been conducted on this relationship. The current thesis addresses this knowledge-gap by first distilling from the literature two classes of emotion theory; Information, and Load; and then systematically testing the explanatory power of these theories. A dual-process framework is employed in order to define low (Type One) and high effort (Type Two) strategies. Information theories predict that negative emotion …

The Characterisation Of The Freezing Damage Response During Flowering In European And Middle Eastern Wheat Cultivars (Triticum Aestivum L), Mohammed Hamdan Edan Al-Issawi

Other Faculty of Science and Engineering Theses

Wheat (Triticum aestivum L.) is occasionally exposed to low temperature during flowering and huge economic losses can occur especially in some key production countries such as Australia. Although it is generally predicted that there will be a rise in global temperature there are still predicted to be risks associated with low temperature for temperate crops. Post head emergence frost damage remains a major constraint to increasing wheat production. Five Iraqi varieties (Abu-Ghariab, Fatah, Sham6, IPA95 and IPA99) were screened for their frost hardiness (LT50). Abu-Ghariab was chosen for further investigations along with the European cv. Claire because the acclimated frost …

Molecular Characterisation Of Clinical And Environmental Isolates Of Vibrio Parahaemolyticus, Hadaf Mahdi Kadhim

Other Faculty of Science and Engineering Theses

The halophilic bacterium Vibrio parahaemolyticus is widely distributed as a natural inhabitant of marine and estuarine environments. Some strains cause gastroenteritis in humans. Clinical isolates are thought to possess virulence factors that are absent from the majority of environmental isolates. Studies were undertaken to differentiate clinical (virulent) and environmental (mainly avirulent) forms of Vibrio parahaemolyticus. Initially, identification and confirmation of a total of 55 V. parahaemolyticus isolates (23 clinical and 32 environmental) was carried out by using selective media, biochemical and nutritional tests. Identity was confirmed by specific polymerase chain reaction (PCR) targeting the toxR gene. In an attempt to …

Visual Images As A Motivational Bridge To Pro-Environmental Behaviour: A Cognitive Approach, Christine Boomsma Jan 2013

Visual Images As A Motivational Bridge To Pro-Environmental Behaviour: A Cognitive Approach, Christine Boomsma

Other Faculty of Science and Engineering Theses

Communicating climate change and other long-term environmental issues to the wider public is a challenging process involving many barriers to action. Visualisations have the ability to overcome these barriers. Furthermore, the benefits of visual images over verbal information have been supported. However, there is a lack of research on how visual images can motivate behaviour. Based on Elaborated Intrusion theory, it is proposed that visual images can be internalised as mental images which can act as a ‘motivational bridge’ for pro-environmental behaviour. Six studies exposed participants to visual pro-environmental messages. Throughout all studies images were internalised as mental images, associated …

The Effect Of Hyperbaric Oxygen Therapy On Osteoclast And Osteoblast Function, Hadil Al-Hadi Jan 2013

The Effect Of Hyperbaric Oxygen Therapy On Osteoclast And Osteoblast Function, Hadil Al-Hadi

Other Faculty of Science and Engineering Theses

Bone remodelling, the process by which the skeleton adapts to environmental changes, is dependent on the actions of osteoclasts that resorb bone and osteoblasts which make new bone matrix. Aberrant remodelling underpins bone loss in several debilitating skeletal diseases such as osteoporosis, metastatic breast cancer and multiple myeloma. Changes in remodelling activity can also arise as a consequence of therapeutic intervention for instance intravenous bisphosphonate treatment is associated with osteochemonecrosis of the jaw and localised osteoradionecrosis is a common side effect of radiotherapy. Hyperbaric oxygen is often used as an adjunctive therapy in the treatment of these disorders. HBO involves …

Motivated Reasoning And Response Bias: A Signal Detection Approach, Dries Trippas Jan 2013

Motivated Reasoning And Response Bias: A Signal Detection Approach, Dries Trippas

Other Faculty of Science and Engineering Theses

The aim of this dissertation was to address a theoretical debate on belief bias. Belief bias is the tendency for people to be influenced by their prior beliefs when engaged in deductive reasoning. Deduction is the act of drawing necessary conclusions from premises which are meant to be assumed as true. Given that the logical validity of an argument is independent of its content, being influenced by your prior beliefs in such content is considered a bias. Traditional theories posit there are two belief bias components. Motivated reasoning is the tendency to reason better for arguments with unbelievable conclusions relative …

Public Attitudes Towards Crime And Punishment In Greece And The Factors Underlying Their Construction, Magdalini Pipini Jan 2013

Public Attitudes Towards Crime And Punishment In Greece And The Factors Underlying Their Construction, Magdalini Pipini

Other Faculty of Arts, Humanities and Business Theses

Public opinion regarding crime-related issues is a challenging matter for researchers and politicians alike. An ill-informed public with regards to crime, punishment and other aspects of the criminal justice system leads to discontent and demands for harsher policies to strengthen public safety. Politicians harness public opinion to secure votes, and this can result in punitive policies that are founded on erroneous beliefs. The objective of this study is to look more deeply into people’s attitudes towards crime and punishment, and to consider why Greek people hold the views that they do and how these views are constructed. A multi-method approach …
