Introduced Cyprinid (Carp) Fishes In Western Australia And Their Management Implications, K. R. Breheny
Introduced Cyprinid (Carp) Fishes In Western Australia And Their Management Implications, K. R. Breheny
Theses : Honours
Australia has no native cyprinid species and five introduced species have established self-sustaining populations. This study examines the cyprinid species present in Western Australia and estimates their distribution. The potential for introduced cyprinids to cause environmental impacts is explained and ameliorative action recommended. The presence and distribution of cyprinid species is assessed by examination of museum records, published literature, reported collections, anecdotal evidence and sampling of wetland habitats. Two species, Carassius nuratus (Goldfish) and Cyprinus carpio (Koi carp) are believed to have established populations and a map of estimated distribution is compiled. The capacity for introduced carp to undergo sudden …
The Filtration Rate, Oxygen Consumption And Biomass Of The Introduced Polychaete Sabella Spallanzanii Gmelin Within Cockburn Sound : Can It Control Phytoplankton Levels And Is It An Efficient Filter Feeder?, Geordie Clapin
Theses : Honours
Sabella spallanzanii, a filter feeding, sabellid polychaete worm which is common in the Mediterranean Sea, was recently discovered in Cockburn Sound, Western Australia. The species has been in Port Phillip Bay, Victoria for about 10 years, where it has spread widely, competes with native species and has economic impacts on the local scallop fishery. In Cockburn Sound, S. spallanzanii has colonised a shallow, sandy area known as the Southern Flats, reaching a mean biomass of 258 gDW m2 , as well as almost all artificial structures such as jetties and navigational marker pylons. A large biomass of this introduced …
Effect Of Carbohydrate Source, Auxin And Endogenous Ethylene Upon Root Induction Of Eucalyptus Marginata Donn Ex Sm. In Vitro, Meredith Magaret Fairbanks
Effect Of Carbohydrate Source, Auxin And Endogenous Ethylene Upon Root Induction Of Eucalyptus Marginata Donn Ex Sm. In Vitro, Meredith Magaret Fairbanks
Theses : Honours
The utilisation of eucalypts around the world is increasing, mainly through the development of plantations. Clonal propagation has become important in some countries for production of such plantation trees. Micropropagation has been utilised to produce clones of trees selected for specific characteristics such as disease resistance, salt tolerance and fast growth rates. However, a suitable micropropagation protocol for all eucalypts has not been produced. One component of the micropropagation protocol, in which there is considerable difficulty, is the induction of adventitious roots on micropropagated shoots. Of particular interest, is the development of these procedures for Eucalyptus marginata (Jarrah) that have …
Towards A Model For Software Project Estimating, Stuart Hope
Towards A Model For Software Project Estimating, Stuart Hope
Theses : Honours
The use and development of software is an integral and critical part of modern industrial society. The outcomes of many software development and maintenance projects have been less than satisfactory with significant numbers being over schedule, lacking in functionality and over budget. These problems are the result of poor management of both the process and the product. One of the major problems to overcome in the management of software development projects is the ability to predict the outcomes early in the project when there are a large number of unknowns. The ability to reliably predict the outcomes in a repeatable …
Growth And Properties Of Chemically Deposited Cds Thin Films, Edward A. Gluszak
Growth And Properties Of Chemically Deposited Cds Thin Films, Edward A. Gluszak
Theses : Honours
Polycrystalline thin films of undoped CdS and In doped CdS (i.e. CdS:In) have been deposited by chemical bath on glass slides and high purity silicon wafers. The effect of different processing conditions (e.g. substrate temperature, doping and air annealing) on film growth, optical transmittance and electrical properties were correlated with the film microstrucutre. The mechanism of chemical bath deposition of CdS thin films from the ammonia-thiourea system is studied. The influence of reaction parameters (i.e. concentration of reactants and pH) on film growth were determined and modeled. Thin film growth is thermally activated with an energy ≈ 5 x 10 …
Young Lions : The Changing Face Of South African Youth Politics 1944-1994, Jubalane Matsebula
Young Lions : The Changing Face Of South African Youth Politics 1944-1994, Jubalane Matsebula
Theses : Honours
The changing face of South African youth politics and the construction of youth identities in official discourse has always been an area of interest. During the struggle against apartheid, the youth category was contested by two diametrically opposed sets of discourse: the liberatory and the conservative. This study is about Black youth politics from 1944 to 1994 with especial reference to the changes in discourses of liberation and the construction of youth within these discourses. It explores the role of young people in the liberation struggle, how they were constituted by others and how they constituted themselves. This study posits …
The Use Of Subjective Ratings Of Perceived Exertion (Rpe) To Estimate Fixed Blood Lactate Concentrations During Incremental Cycle Ergometer Exercise, Keith Robert Scotson
The Use Of Subjective Ratings Of Perceived Exertion (Rpe) To Estimate Fixed Blood Lactate Concentrations During Incremental Cycle Ergometer Exercise, Keith Robert Scotson
Theses : Honours
Prescription of exercise intensity based on blood lactate concentration has become widely accepted in recent years. The methods used to directly measure blood lactate concentration however, can be costly, time consuming and potentially hazardous to both subject and tester. Recent studies indicate that a strong relationship exists between subjective feelings of strain experienced during exercise and changes in the appearance of blood lactate. This raises the possibility that subjective ratings of perceived exertion (RPE) can be used to simply and effectively estimate and monitor appropriate exercise intensity based on blood lactate concentration. In order to test this theory two groups …
The Impact On Juries Of Pre-Recording Children's Evidence, Josephine Hubble
The Impact On Juries Of Pre-Recording Children's Evidence, Josephine Hubble
Theses : Honours
The impact on juries of pre-recording children's evidence was investigated. University undergraduate students (N = 123; 91 females, 32 males) volunteered to participate in the study as mock jurors. Participants either watched a videotape or read a transcript of a simulated trial involving a child sexual abuse case. Participants who watched the videotape saw the child give evidence either by closed circuit television or by a pre-re-cording. Participants who read the transcript were advised the child's evidence had been given via closed circuit television or had been pre-recorded. After viewing the videotape or reading the transcript, participants completed a questionnaire …
Developmental Aspects : Metacognition And Problem Solving, Roseanne Gibson
Developmental Aspects : Metacognition And Problem Solving, Roseanne Gibson
Theses : Honours
Mathematical problem solving has been the focus of recent curriculum reform. Researchers have investigated factors that appear to influence mathematical problem solving: one of these factors is metacognition. This study identified metacognitive aspects and investigated the relationship of metacognition and age in the context of mathematical problem solving. Twenty four children were randomly chosen: eight children from years two. four and six. The children were given the same non-routine problem to solve. A semi-structured interview and observation protocol were developed and used to determine students' metacognitive aspects. There was an extensive descriptive analysis of metacognitive aspects and a systematic quantification …
The Design And Implementation Of A Toolkit For The Creation Of Virtual Environments, Jesse Kinross-Smith
The Design And Implementation Of A Toolkit For The Creation Of Virtual Environments, Jesse Kinross-Smith
Theses : Honours
Virtual Reality is a field that is steadily increasing in popularity and interest. New developments in both hardware and software have empowered developers with new devices allowing faster and better quality interaction with virtual environments. However, the emphasis of research in virtual environments has been more concerned with development of new display and input devices, as opposed to the investigation of different methods of interaction that a three-dimensional environment offers. This project designs and implements a three-dimensional, interactive, virtual environment development system upon an existing three-dimensional rendering engine. The aim of the project is to allow users to generate virtual …
Nonresidential Father Perception Of Father-Child Relationships: An Exploratory Analysis Of Family Functioning, Wendy J. Nicholls
Nonresidential Father Perception Of Father-Child Relationships: An Exploratory Analysis Of Family Functioning, Wendy J. Nicholls
Theses : Honours
Nonresidential father experiences of family life with their children lack attention in the literature. Nonresidential fathers often suffer considerably, as they attempt to continue their parenting role with limited access lime. Consequently, their relationships with their children may suffer, sometimes resulting in visitation ceasing altogether. Father contact is important to the developmental and psychological well-being of children, yet is often hindered by restricted access, distance, parental conflict and the father's emotional state. Nonresidential father perspectives of family life with their children are explored in this study, to gain insight into nonresidential father experiences. This study replicated a study conducted by …
The Effects Of A Sense Of Humour On Empathic-Responses : Testing Positive And Negative Affect As Mediating Variables, Michael Francis Sheehan
The Effects Of A Sense Of Humour On Empathic-Responses : Testing Positive And Negative Affect As Mediating Variables, Michael Francis Sheehan
Theses : Honours
Research investigating individual differences in empathy-related responding has shown sympathy (an other oriented response involving concern) and perspective taking (the psychological adoption of another's point of view) to be related to emotional regulation and more positive affect, and personal distress (an egoistic reaction to another's distress) to be associated with overarousal and more negative affect Separate research investigating the stress-moderating effects of humour has linked coping humour to reduced negative affect and the maintenance of positive affect. The present study tested a model that hypothesised that coping humour would have an indirect affect on each empathy-related variable through positive and …
Student's Attitude To Using The Internet At School After Limited Classroom Exposure, Anna Hu
Student's Attitude To Using The Internet At School After Limited Classroom Exposure, Anna Hu
Theses : Honours
This study focused on student's attitude to using the Internet at school. A questionnaire (the School Internet Attitude questionnaire) measuring student attitude to using the Internet at school incorporating three dimensions (cognitive, behavioural and affective) was administered twice to a sample of 64 Year 12 students from a Perth Metropolitan Independent school. The questionnaire was administered before and after a six lesson 'exposure' (the limited classroom exposure) to the Internet. Pre and post test attitude measures of all students were compared using dependent sample t_ test to determine if there were significant differences in student's attitude after the limited classroom …
Arbitrary Views Of High-Dimensional Space And Data, Andrew Ellerton
Arbitrary Views Of High-Dimensional Space And Data, Andrew Ellerton
Theses : Honours
Computer generated images of three dimensional scenes objects are the result of parallel/perspective projections of the objects onto a two dimensional plane. The computational techniques may be extended to project n-dimensional hyperobjects onto (n-1) dimensions, for n > 3. Projection to one less dimension may be applied recursively for data of any high dimension until that data is two-dimensional, when it may be directed to a computer screen or to some other two-dimensional output device. Arbitrary specification of eye location, target location, field-of-view angles and other parameters provide flexibility, so that data may be viewed-and hence perceived-in previously unavailable ways. However, …
Phenolic And Lignin Concentration As An Indicator Of Resistance To Phytophthora Cinnamomi In Banksia Species, Sandra Jane Nicoski
Phenolic And Lignin Concentration As An Indicator Of Resistance To Phytophthora Cinnamomi In Banksia Species, Sandra Jane Nicoski
Theses : Honours
Phytophthora cinnamomi Rands, a soilborne fungus, is regarded as one of the most devastating pathogens yet recorded in natural ecosystems. The disease, caused by P. cinnamomi, poses an enormous threat to the flora of the southwest. The Proteaceae, in particular, contribute considerably to species richness and provide the fundamental floristic structure of many south-western plant communities. The genus Banksia, a member of the Proteaceae, is very susceptible to disease caused by P. cinnamomi. Three species, namely B. attenuata, B. grandis and B. menziesii. Were established in an aeroponics system under glasshouse conditions. Trials were conducted to optimise growing conditions in …
Development And Optimisation Of A Micellar Electrokinetic Capillary Chromatography Method For The Separation And Identification Of Phenolics From Eucalypt Species, Andrew J. Tromans
Development And Optimisation Of A Micellar Electrokinetic Capillary Chromatography Method For The Separation And Identification Of Phenolics From Eucalypt Species, Andrew J. Tromans
Theses : Honours
Several buffers were examined for their ability to separate a complex mixture of phenolic compounds using micellar electrokinetic capillary chromatography (MEKC). The phenolic mixture included simple phenols, phenolic acids and coumarins. Of the different buffers examined, 6 mM borate, 10 mM phosphate, 100 mM SDS, pH 8.3 gave the best separation. The ability of organic modifiers, complexation agents such as α cyclodextrin, β cyclodextrin and mixed SDS I Brij 35 micelles to improve the separation and peak retention time reproducibility of the buffer system was investigated. Baseline separation of the 18 phenolics was achieved by the 6 mM borate, 10 …
Simulink Implementation Of A Cdma Transmitter, Visalakshi Ramakonar
Simulink Implementation Of A Cdma Transmitter, Visalakshi Ramakonar
Theses : Honours
An implementation of a Code Division Multiple Access (CDMA) transmitter has been developed using SIMULINK and MATLAB. This transmitter uses a modified carrier in modulation. This modified carrier, which is frequency modulated, has been shown to reduce intersymbol interference (ISI) and multiple access interference (MAl). These two types of interference are caused by multipath propagation which results in delayed versions of the original signal. The benefits of this modified modulation technique are apparent when there are delays involved. The spreading sequences used are 7- bit Gold codes which allow a maximum of nine users. The initial trials of the transmitter …
Modelling The Effects Of Rehabilitation And Changed Agricultural Practices In A Saline-Affected Rural Catchment, M. K. Heller
Modelling The Effects Of Rehabilitation And Changed Agricultural Practices In A Saline-Affected Rural Catchment, M. K. Heller
Theses : Honours
The Bremer river catchment, on the South-coast of Western Australia, is typical of most river catchments in this region in that it has been seriously affected by sedimentation, salinisation and eutrophication brought on by the gradual dominance of agricultural land management practices. Vegetated rehabilitation and changed agricultural land management practices (ie minimum / zero tillage) have now been widely adopted throughout the catchment in response to these degradation issues. This study examined the potential impact minimum / zero tillage, vegetated rehabilitation and remnant vegetation could have on both a farm and catchment wide scale. A Geographical Information System was developed …
Chief Seattle's Speech(Es): Ambivalent Idealizations And Emplacing The Uprooted 'Origin', Paul J. O'Malley
Chief Seattle's Speech(Es): Ambivalent Idealizations And Emplacing The Uprooted 'Origin', Paul J. O'Malley
Theses : Honours
This thesis traces the narcissistic dynamics behind mounting idealizations of a Native American Indian, Chief Seattle, and his renowned speech of 1854. In my work I draw from psychoanalytic, poststructuralist, 'post-colonial', and translation theories, as well as from contemporary Indian scholarship. I develop my own provisional model of what I term "Narcissistic Drift", providing a means of charting the intertextual dynamics driving colonial representations of otherness to converge progressively with stereotypical norms. Where previous Seattle studies have tended to concern themselves with issues of textual 'authenticity', I build on such work to consider how an indigenous speech 'uprooted' from its …
An Analysis Of Potential Incompatibility Between The Acts Amendment (Evidence Of Children And Others) Act 1992 And Defendants' Rights, V. F. Pearson
An Analysis Of Potential Incompatibility Between The Acts Amendment (Evidence Of Children And Others) Act 1992 And Defendants' Rights, V. F. Pearson
Theses : Honours
The need to balance the needs and rights of all parties is a central consideration in legal procedure. This is no simple task, however, when the interests of the defendant are often in direct contrast to those of the witness. Much of the contention arises from the ambiguity associated with the nature of both victims' and defendants' rights and the lack of clear guidelines for the resolution of conflict where such competing interests are involved. Because Australia has no document precisely delineating the nature and content of individual rights, the result is a reliance on an ill-defined combination of common …
Patterns Of Anger, Attribution, And Appraisal, Andrew J. Ellis
Patterns Of Anger, Attribution, And Appraisal, Andrew J. Ellis
Theses : Honours
A single study investigates two cognitive theories of anger arousal, and the hostile attribution bias (HAB) phenomenon from the aggression literature. It was argued that the role of B. Weiner’s (1985, 1986) casual attribution dimension of intentionality has been underestimated in anger arousal; and it was hypothesised that when attributions of intentionality increase anger arousal increases. R. S. Lazarus and K. A. Smith's ( 1988) appraisal theory holds that emotions arc aroused in response to personally relevant events, and without this appraisal process causal attibutions are insufficient to evoke emotions. Based on this it was hypothesised that appraisal components are …
An Examination Of The Influence Of Court Interpreters Upon Attributions Of Defendant And Plaintiff Culpability, Grace Frances
An Examination Of The Influence Of Court Interpreters Upon Attributions Of Defendant And Plaintiff Culpability, Grace Frances
Theses : Honours
An expressed reluctance of the courts to employ interpreters has been challenged on the basis that a failure to provide such assistance to the Non-English Speaking (NES) witness contravenes the principles of natural justice. Further, NES defendants risk being misunderstood and incapacitated in their ability to effectively communicate the intended meaning of the evidence they are giving. In order to determine whether the presence of an interpreter exerts influence upon attributions of culpability given to a NES defendant, it was .important to identify whether evaluations were based on the interpreter's presence or on the defendant's ethnicity. Therefore, three trial conditions …
Word Processors In Secondary English : A Survey And Discussion Of Usage In West Australian High Schools, Stuart D. Hakeney
Word Processors In Secondary English : A Survey And Discussion Of Usage In West Australian High Schools, Stuart D. Hakeney
Theses : Honours
The word processor would seem to have many positive applications to student writing in the English classroom. Writers working in the field (Chandler, 1987; Jenkins, 1989; Snyder, 1994) all agree that whether the technology is used as an editing aid to help poor hand writers and weak spellers get through the "grind" of writing, or as a dynamic tool which can be used as a new and exciting way of making meaning, its usefulness in subject English should not be overlooked. However, initial inquiries undertaken as part of this study, suggested that word processing technology had been largely ignored in …
A Whole School Approach To Literacy Intervention, G. J. Raison
A Whole School Approach To Literacy Intervention, G. J. Raison
Theses : Honours
This research project reports on the process of developing a whole school approach to literacy intervention in one multi-ethnic, designated disadvantaged primary school. The study describes how teachers worked collaboratively, using items from a resource package Successful Intervention K-3 Literacy, to critically reflect on their pedagogy in their efforts to better address the needs of those students in their classes who appeared to have difficulties with literacy learning. A modified action research method was used by the teachers to devise a context-specific school plan. Within the plan, they allocated time and resources to assist them as they shared and developed …
Migrant Woman As 'Undecidable' : Migrant Subjectivity, The Crocodile Fury By Beth Yahp And The Mule's Foal By Fontini Epanomitis, Sally Cloake
Theses : Honours
In this thesis I demonstrate how a notion of decentred subjectivity better describes marginal subject positions than the concept of unified subjectivity which depends on a discriminatory binary conceptualisation. I identify the migrant position as an aporia from which to deconstruct such concepts as unified subjectivity, as the migrant refuses classification according to dichotomous structures. I use Derridean metaphors to show the falseness and unexamined essentialism inherent in binary oppositions. I use a combination of theorists, and especially Helime Cixous, to augment my primarily Derridean reading of migrant subjectivity within the texts: The Crocodile Fury by Beth Yahp and The …
Nutritional Problems And Information Needs Of Patients Receiving Chemotherapy And Radiation Therapy, Margaret Joan Robinson
Nutritional Problems And Information Needs Of Patients Receiving Chemotherapy And Radiation Therapy, Margaret Joan Robinson
Theses : Honours
Nutritional status is a major factor in determining the successful outcome of treatment for cancer. The combined effect of cancer, and the treatment for cancer, has the potential to severely impair nutritional status. The purpose of this study was to investigate the incidence and severity of treatment-related side-effects which affect nutritional status in cancer patients and to determine the sources and helpfulness of information about nutrition which had been utilised by patients. A descriptive study was used to investigate two groups of patients, one group who was receiving chemotherapy, and the other, radiation therapy. A questionnaire developed by the researcher …
Someone's Calling Your Swatch: Youth, Technology And Power, Su-Lyn Tan
Someone's Calling Your Swatch: Youth, Technology And Power, Su-Lyn Tan
Theses : Honours
Common assumptions about youth and youth culture exist in academic, as well as other adult cultures. These assumptions underlie policy decisions, programming choices, and even the way we (as adults) treat youth. This study proposes to examine Singaporean youth and their use of pagers, in terms of Foucauldian theories of power; in an attempt to draw critical attention to these common assumptions. The intention is to explore the ambiguities of such common assumptions as sites of power relations; relations that are inherent to all societies in one way or another. The pager is not a conventional focus for communication research. …
The Effect Of Expert Testimony On Juror Decision Making In Eyewitness Identification Cases, Pamela J. Sullivan
The Effect Of Expert Testimony On Juror Decision Making In Eyewitness Identification Cases, Pamela J. Sullivan
Theses : Honours
The provision of expert testimony for the defence has been demonstrated to sensitise jurors to the variables that may reduce the reliability of an eyewitness identification (Cutler, Dexter, & Penrod, 1989). However, research examining the variables that reduce identification reliability has revealed conflicting findings (Yuille & Cutshall, 1986). Given this disparity in psychological opinion, a situation may arise where opposing expert testimony for the prosecution and the defence is delivered within the same criminal trial This thesis examined the effect of each form of expert testimony about eyewitness identification issues on the decision of the individual juror. The decision making …
An Investigation Into An Effective Method Of Automatically Analysing Oracle Applications To Count Function Points, J. L. Wong
Theses : Honours
Function Point Analysis (FPA) is a synthetic software estimation metric used for computing the size and complexity of applications. It was first introduced by Allan. J. Albrecht during the mid-seventies, as a result of a lengthy research based on applications that were developed using COBOL and PL/1 programming languages. The purpose of this research· is to investigate the possibility, and the most effective method, of automatically performing a Function Point Analysis on Oracle applications that consist of Oracle Forms and Oracle Reports. The research revealed a seemingly lack of other researches on this topic. As FPA was invented a few …
A Functional Group Approach To Detecting Shifts In Macroalgal Communities Along A Disturbance Gradient, J. C. Phillips
A Functional Group Approach To Detecting Shifts In Macroalgal Communities Along A Disturbance Gradient, J. C. Phillips
Theses : Honours
A recently proposed hypothesis argued that morphologically and functionally similar macroalgae could be grouped to study the structure of macroalgal communities. It was argued that these functional groups can be used to predict changes to community composition that result from disturbance. This study examined whether the functional group model held in detecting changes in macroalgal community structure within one bioregion, by applying it to a habitat exposed to different levels of physical disturbance associated with wave exposure. Results obtained using a functional group approach were compared to those obtained using a species level approach. Three parallel reef lines in Marmion …
