Measuring The Impact Of Church Externalities On House Prices, Gabriel K. Babawale

Khazar Journal of Humanities and Social Sciences

This study extends literature that empirically investigates the impact of the externalities generated by churches on prices of nearby residential properties with particular reference to selected areas in Lagos, Nigeria; but with some implications for economic studies in other parts of the world The study hypothesized that the proximity of a church has nosignificant effect (positive or negative) on house prices. The hypothesis is tested with a standard hedonic pricing model using the net rents of 450 apartments (flats) across the study area. The results confirmed the more common belief that neighborhood churches, particularly the larger ones, impact on the …

Reinforced Concrete Deterioration Of A 100 Year Old Structure In A Marine Environment, Ross O'Donovan

Theses

The current study investigates the deterioration of a 100 year old bridge located in a harsh marine environment. Constructed in 1908 - 1909 the Mizen Head Footbridge was one of the oldest reinforced concrete bridges in Ireland. The demolition of the bridge in 2009 provided a unique opportunity to examine its service life and to extract samples for analysis and investigation. A review of the construction of the bridge, and its maintenance history are presented, with a view to analysing their influence on the behaviour of the concrete.

Reinforcement corrosion due to chloride attack was identified. A focused study indicates …

An Investigation Into The Potential Of Increasing The Span Of Solid Slab Deck Bridges, Eamonn Kiernan

Theses

Solid slab deck bridges are a common type of structure employed for short to medium span bridges. They may be of rapid build nature if they are made up of prestressed precast sections with concrete infill deck.

The aim of this research was to investigate the potential to increase the span of solid slab deck bridges by the employment of high strength concrete (HSC), lightweight aggregate concrete (LWAC) and the use of a voided deck.

The analysis undertaken in the research was based on a bridge, which was recently constructed in Cork; the bridge was constructed using MY beam sections, …

Structural Behaviour Of Semi-Continuous Steel End Plate Connections, Niall Scollard

Theses

This report focuses on determining the joint stiffness and moment capacity values for semi-continuous (semi-rigid) connections in steel framed structures. When designing a beam to column connection, the assumption that the Joint is either fully continuous or fully pinned may not be entirely valid; it may be more realistic to classify the connection as intermediate between fully pinned and fully continuous.

The development of “the component method”, which is utilised in IS EN 1993-1-8 (EC3) to determine design values of the joint properties is described. A software solution was created using Microsoft Excel to carry out calculations in accordance with …

The Potential For The Elimination Of Expansion Joints And Bridge Bearings From Existing Road Bridges In Ireland, Conor Keena

Theses

This research was focused on determining the feasibility of eliminating expansion joints and bridge bearings from existing short to medium span road bridges in Ireland. It is possible that this could provide a significant long-term economic benefit to bridge owners. A literature review was carried out as part of the research. This included investigations into research conducted in the areas of thermal movements of bridges, concrete creep and shrinkage, soil-structure interaction, lifetime costing, design standards and finite element analysis, and the elimination of bridge expansion joints in other countries.

Finite element analyses were carried out on two existing road bridges. …

An Investigation Of Transverse Load Distribution In Masonry Arch Bridges, Helen Dunne

Theses

Masonry arch bridges comprise a significant proportion of the bridge stock both nationally and internationally. They have proven to be enduring structures, far surpassing their design lives and with relatively low life-cycle costs, are environmentally friendly (Sustainable Bridges, 2007).

New masonry arch bridges are not generally constructed. However, their ageing materials paired with ever increasing traffic loads have led to the necessity for their periodic re-assessment. Masonry arch bridge design was predominantly by rule of thumb and their re-assessment has been subject to a number of simplified assumptions. One such simplification, the bridge “effective width” is studied in this thesis. …

Polymer Micro-Grippers With An Integrated Force Sensor For Biological Manipulation, Re Mackay, Hr Le, S Clark, Ja Williams

School of Biological and Marine Sciences

The development of a novel micro-system integrating SU-8 polymer micro-grippers with a tensile force sensor for handling and characterizing the mechanical properties of delicate biological materials, such as fibrils, is presented. The micro-grippers are actuated by the electro-thermal effect and have gripping forces comparable to the common 'hot-and-cold-arm' grippers. A robust finite element model was developed to investigate system performance and validated experimentally. A new micro-mechanical calibration method using a piezoelectric manipulator with a micro-force measurement system was successfully applied to test the structure. Both FEA simulation and micro-mechanical testing results indicated that the system could fulfil the requirements for …

Modeling Speech Imitation And Ecological Learning Of Auditory-Motor Maps, C Canevari, L Badino, A D'Ausilio, L Fadiga, G Metta

School of Engineering, Computing and Mathematics

Classical models of speech consider an antero-posterior distinction between perceptive and productive functions. However, the selective alteration of neural activity in speech motor centers, via transcranial magnetic stimulation, was shown to affect speech discrimination. On the automatic speech recognition (ASR) side, the recognition systems have classically relied solely on acoustic data, achieving rather good performance in optimal listening conditions. The main limitations of current ASR are mainly evident in the realistic use of such systems. These limitations can be partly reduced by using normalization strategies that minimize inter-speaker variability by either explicitly removing speakers' peculiarities or adapting different speakers to …

Herbivory By Parma Mccullochi (Pomacentridae) : Its Role As An Ecosystem Engineer In Temperate Algal-Dominated Reefs, Frederico Vitelli

Theses: Doctorates and Masters

Pomacentridae is one of the most representative families of herbivorous fishes inhabiting both tropical and temperate reefs, yet the vast majority of studies examining feeding within this family have been undertaken in tropical rather than temperate regions. Despite the high abundances of the pomacentrid Parma mccullochi in temperate waters of Western Australia, and their likely importance in removing algae from reefs in the region, there is a lack of information on their diet and their impact on the reef algal community. This study aims to determine the role of Parma mccullochi as an ecosystem engineer on temperate algal-dominated reefs in …

This study considered the impact of the changing nature VET policy on trainers of VET. The study …

Women Who Study: Balancing The Dual Roles Of Postgraduate Student And Mother, Bailey Bosch

Theses: Doctorates and Masters

Although the value of educating mothers has been established in the previous research, little is known about the experiences of mothers who participate in higher education. What is known supports a largely negative portrayal of the experience; it seems that it is a difficult journey, filled with tension. This thesis reports on an exploration of the experiences of mothers who are postgraduate students in Australia. The research comprised of two phases: the first phase was a narrative study of the experiences of 14 Australian postgraduate student mothers. The second phase comprised of a Q-method study of 75 postgraduate student mothers, …

Improving Evaluations Of Anti-Bullying Programs In Schools, Thérèse Shaw

Theses: Doctorates and Masters

Bullying at school is associated with negative social, psychological and academic outcomes for both the victimised student and the perpetrator. As a consequence, national strategies to address bullying have been implemented in numerous countries, and education sectors and schools have increasingly directed resources to the problem. To ensure resources are allocated to programs and strategies that will prevent and successfully respond to bullying in schools, and therefore prevent harm to students, evidence of program effectiveness is required. Evaluations of anti-bullying programs in schools have had mixed results and there is a lack of robust evidence as to their impact. Several …

At the same time, Perth’s local indie pop/rock music industry has undergone tremendous growth …

Factors Influencing The Capacity Of Communities To Respond To Coastal Erosion In The Upper Gulf Of Thailand, Chatchai Intatha

Theses: Doctorates and Masters

Local communities must have a capacity to ameliorate coastal erosion impacts. Since coastal erosion operates over long time frames, understanding this capacity, or the abilities of communities to respond to the impacts and recover to maintain community functions, requires analysis of the past and the present. This study explores factors which influence the capacity of communities to respond to coastal erosion and conversely how exposure to coastal erosion itself affects community capacity.

Mixed methods research was used to investigate the views of respondents in seven coastal villages in the upper Gulf of Thailand, three from an area that has experienced …

Effects Of Pulsed Electromagnetic Field Therapy On Symptoms Associated With Eccentric Exercise-Induced Muscle Damage, Henry Banyard

Theses: Doctorates and Masters

Unaccustomed exercise consisting of eccentric contractions induces muscle damage that is characterised by muscle weakness, soreness, swelling and increased muscle stiffness. These symptoms affect daily activities and athletic performance; therefore, interventions to attenuate the symptoms and enhance recovery from muscle damage are necessary. Pulsed electromagnetic field therapy (PEMFT) is anecdotally reported to increase muscle blood flow and oxygenation to enhance tissue healing. One previous study showed that PEMFT was effective for alleviating muscle soreness and losses in range of motion after exercise. However, studies investigating the effect of PEMFT on recovery of muscle strength following eccentric exercise are lacking. The …

Metapopulation Theory Explains Black-Stripe Minnow (Pisces: Galaxiidae, Galaxiella Nigrostriata) Distribution In Seasonal Wetlands In South-West Western Australia, David M. Galeotti

Theses: Doctorates and Masters

The objective of this project was to determine if Galaxiella nigrostriata populations could belong to a metapopulation. Metapopulation theory describes how multiple populations with occasional connectivity are a ‘population of populations’. Some populations’ habitats have optimal conditions (source habitats), others experience regular extinctions (sink habitats). Connectivity allows repopulation of extinct or uninhabited habitats. Galaxiella nigrostriata occurred randomly in 11 seasonal wetlands in the Kemerton wetland complex in south-west Western Australia over a 16 year period. The wetlands did not appear to be connected.

Around 70% of wetlands on the Swan Coastal Plain in south-west WA have been filled or degraded …

Evaluating Residential Satisfaction With An Innovative Dual Water Supply System In Water Sensitive Urban Development, Raju S. Dhakal

Theses: Doctorates and Masters

The Australian water industry is facing two major challenges: a rise in water demand due to a growing population and a decrease in rainfall availability due to a drying climate. This situation has triggered a re-evaluation of traditional water schemes and promoted consideration of alternatives for sustainable urban water management. One possibility is to replace drinking water usage in garden and outdoor irrigation with non-potable groundwater. This could save almost half of the water supplied in the residential sector, which is the biggest consumer of scheme water in most Australian cities. A major hurdle for the success of such fit-for-purpose …

Magnetocardiography In Unshielded Environment Based On Optical Magnetometry And Adaptive Noise Cancellation, Valentina Tiporlini

Theses: Doctorates and Masters

This thesis proposes and demonstrates the concept of a magnetocardiographic system employing an array of optically-pumped quantum magnetometers and an adaptive noise cancellation for heart magnetic field measurement within a magnetically-unshielded environment.

Optically-pumped quantum magnetometers are based on the use of the atomic-spin-dependent optical properties of an atomic medium. An Mxconfiguration- based optically-pumped quantum magnetometer employing two sensing cells containing caesium vapour is theoretically described and experimentally developed, and the dependence of its sensitivity and frequency bandwidth upon the light power and the alkali vapour temperature is experimentally demonstrated. Furthermore, the capability of the developed magnetometer of measuring very weak …

Stakeholders Perspective On Sustainable Technology Selection To Achieve Zero Carbon Retail Buildings, Syeda Zainab, Wei Pan, Steve Goodhew, Alba Fuertes

School of Art, Design and Architecture

In the design and construction of sustainable retail buildings, there are various stakeholders involved with the overall aim of selecting appropriate sustainable technologies to reduce energy consumption and carbon emissions. Previous studies and literature review indicate there is no comprehensive selection process to assist stakeholders. This can be classified as a complex multi-criteria decision problem due to the high number of alternatives, potential solutions and variety of stakeholders (e.g. clients, professional advisors, end-users) with multiple, often conflicting, objectives leading in turn to the slow take-up of sustainable technologies. There is a demand for a systematic and effective evaluation tool for …

Financial support is among the factors affecting the success of SMEs. However, studies on the financial practices among successful SMEs in Malaysia are still limited. An understanding of the financial practices of this particular group of SMEs is essential in developing a supportive financial framework to achieve national agenda for improving SMEs sustainability and increasing the overall SMEs’ contributions to the Malaysian economy. This research investigates the financial practices among successful …

The Mediating Role Of Entrepreneurial Leadership: An Investigation Of The Competitiveness Of Smes In The Uk South-West Food And Drink Manufacturing, Lise Hunter

Plymouth Business School Theses

ABSTRACT It has long been argued that Social Capital, a concept represented by the value embedded in the social relationships of individuals or collectives constitute strategic resources for individuals and organisations. Social networks are thus perceived by businesses, particularly small and medium enterprises, as a means to access those resources, for example gaining privileged access to strategic information that could secure financial resources. In reality, and because of the inherent characteristics of Social Capital, entrepreneurs or business owner/managers who effectively use resources available within social networks are driven by a clear and compelling vision and sustained by a set of …

Optimising Supply Chain Performance Via Information Sharing And Coordinated Management, Wei Xu

Plymouth Business School Theses

Supply chain management has attracted much attention in the last decade. There has been a noticeable shift from a traditional individual organisation-based management to an integrated management across the supply chain network since the end of the last century. The shift contributes to better decision making in the supply chain context, as it is necessary for a company to cooperate with other supply chain members by utilising relevant information such as inventory, demand and resource capacity. In other words, information sharing and coordinated management are essential mechanisms to improve supply chain performance. Supply chains may differ significantly in terms of …

The Construction Of Local Road Safety Issues: When Lay And Professional Discourses Collide, Stephen Ball

Plymouth Business School Theses

Highway Authorities in the United Kingdom have jurisdiction to control, maintain and improve the local highway network, and the Road Traffic Act 1988 places a duty on such authorities to take preventative measures to reduce road casualties. As such, engineers working for the Highway Authority are on the ‘front-line,’ and are required to deal directly with lay concerns relating to road safety. This study investigates the nature and characteristics of how local road safety issues are raised and how engineers respond to such issues in a local authority setting. A grounded theory methodology was applied in the collection and analysis …
