Parent Involvement In A Year One In-Class Reading Practice Program, Sheelagh Tillotson

Theses : Honours

Parents play a crucial role in their children's literacy development, and their influence on early reading attitudes is profound. Many successful programs have been developed in England, US, Australia and New Zealand to involve parents in assisting their children's reading both at home and at school, but research has also shown that there are a number of difficulties associated with instigating classroom-based programs. The purpose of this study was to investigate an existing, classroom-based reading practice program involving parents and to analyse how and whether it was successful for each participating group: that is parents, students and the teacher. The …

To Develop And Implement A Quality Assurance System Based On Hazard Analysis Critical Control Points (Haccp) To A Cook-Freeze Operation: Research Project, Denisa Baca

Theses : Honours

The purpose of this study was to identify and develop a suitable quality assurance system based on Hazard Analysis Critical Control Points (HACCP), which was implemented to the ‘cook-freeze' operation, currently employed at Healthcarc Foods.

Theses : Honours

The search for the chemical or set of chemicals that act as a germination stimulant in Lactuca sativa v. Grand rapids (a variety of lettuce seed) was the underlying basis of this project. Through the development of a solid phase extraction (SPE) system different fractions of smoky water were tested for their effects on germination enhancement. The project targeted streamlining the amount of solvents as well as time used in past research on smoky water. Previously, several steps involving high perfo1mance liquid chromatography (HPLC), thin layer chromatography (TLC) and Gas Chromatography (GC) were employed. This project used SPE cartridges to …

The Effects Of Context And Number Of Presentations On Repetition Priming, Terry A. Simpson

Theses : Honours

When a stimulus such as a word is presented twice, the identification of the word on the second presentation is usually facilitated, reflecting repetition priming. This facilitation can occur without a person's awareness and is often referred to as reflecting implicit memory. The present study investigated the effects of number of presentations of words and the context in which words were presented on repetition priming. The study measured reaction times on a lexical decision task in which the participants decided whether a string of letters constituted a word or a non-word. Repetition priming on this task was determined by comparing …

El Gaucho Como Personaje Historico En La Literatura Argentina, Nora M. C. De Sidoruk

Theses : Honours

The aim of this study is to analyse how three different Argentinian writers: Domingo Faustino Sarmiento, José Hernández and Ricardo Güiraldes characterise in their work the life of the Argentinian cowboy, the gaucho. Using real life models, they describe the life and personality of this countryman after the colonial times and until the first part of the twentieth century. Domingo Faustino Sarmiento (1811-1888), an essayist, politician and educationalist, wrote Facundo in 1845, an essay about the life of the "caudillo" (chieftain) Juan Facundo Quiroga and one of the classics of Argentinian literature. Facundo is a study of the Argentinian customs …

Reefs As Contributors To The Diversity Of Epiphytic Algal Communities In Seagrass Meadows, B. R. Van Elvan

Theses : Honours

It has recently become dogma that reef systems arc a source of diversity to algal epiphyte communities in adjacent seagrass meadows. While this theory had not been tested, it was often cited as the reason for unexpected results in algal studies and marine pollution monitoring. This study examined whether reefs do in fact contribute to the diversity of seagrass epiphytes by testing the effect of distance from reef on seagrass epiphyte communities. The study was conducted in the vicinity of Carnac and Garden Islands and Parmelia Bank, off the coast of Fremantle, Western Australia. Three habitat types were selected as …

Comparison Of Median Indicator Kriging With Full Indicator Kriging In The Analysis Of Spatial Data, Donna Hill

Theses : Honours

In the earth sciences, and particularly in the mining of precious metals, data distributions are often strongly positively skewed. When making decisions on the potential profitability of a gold mine, for example, the high values of the distribution are of particular importance. Indicator kriging provides estimates of cumulative distribution functions from which grade tonnage curves may be calculated. Multiple or full indicator kriging requires a semivariogram to be modelled and a kriging system of equations to be solved for each cut off. This can be time consuming and modelling indicator semivariograms at high cut-offs may be difficult because of the …

Behavioural Contexts For The Expression Of Modern Racism: The Simulated Juror Paradigm, Murray Riggs

Theses : Honours

The central tenet of modem racism theory is that, although overt prejudice seems to have declined, subtle forms of prejudice are still pervasive. The theory predicts that members of a majority racial group will discriminate against members of a minority racial group only when they feel that they can do so without appearing to be prejudiced. Thus, the occurrence of discrimination depends upon the nature of the behavioural context. The purpose of the present study was to explore the implications of modern racism theory in the behavioural domain by employing the simulated juror paradigm. The participants, 338 randomly selected residents …

Categorical And Coordinate Spatial Judgements In Face Recognition, Jill E. Russell

Theses : Honours

The role of the cerebral hemispheres in processing spatial relationships is outlined in Kosslyn 's (1987) theory that states that there are two separate subsystems for processing spatial relations: one located in the left hemisphere (LHem) that is more efficient at processing categorical information, and one in the right hemisphere (RHem) that is more efficient at processing coordinate information. To test Kosslyn's theory, this study manipulated two IVs in a within-subjects design, task: categorical and coordinate; and visual field (VF): left and right Male and female face stimuli were presented in either the left visual field (LVF) to the (RHem) …

Theses : Honours

A replication and extension of Rigby and Slee's (1993) study and an investigation of Seligman, Reivich, Jaycox and Gillham's (1995) theory of self-esteem was conducted in one private primary school in Western Australia. The aim of the study was to examine the relationship between the age and gender of victims of bullying with self-esteem of the students and their attitudes towards attending school (Rigby & Slee, 1993), and their explanatory style (Seligman et al., I 995). Four anonymous questionnaires: Peer Relations Assessment Questionnaire (Rigby & Slee, 1997), Self-Esteem Inventory (Coopersmith, 1989), Children's Attributional Style Questionnaire (Seligman, Kaslow, Alloy, Peterson, Tanenbaum …

Policing For Profit: The Drug War’S Hidden Economic Agenda, Eric D. Blumenson, Eva Nilsen

Faculty Scholarship

In the following pages, we first describe in more detail how the Drug War’s financial largess has kept its soldiers in business. We then discuss the destructive impact of this economic regime, marshaling evidence to show that the corruption of law enforcement priorities and wholesale miscarriages of justice can be attributed to the operation of these incentives. Finally, we explore potential legal and legislative remedies through which law enforcement may regain its bearings.

Our investigation focuses on the economic underpinnings of current drug law enforcement policy. Drug policy also raises an extraordinarily broad range of moral, health, and criminological concerns, …

A Study Of Aeration Effects On Direct Acting Hydraulic Valve Train Systems, Deborah Green

Theses

The amount of research in the area of mass transfer of air as a bubble in hydraulic fluid or lubricant is very limited. There are only a few studies on the interaction of oils with air, especially knowledge of air solubility of the oil and diffusivity of dissolved air in oil, namely aeration. This paper will study the effect of aeration on a direct acting hydraulic valve lifter system in an internal combustion engine. Aeration is, primarily, influenced by hydrodynamic factors such as, design features of the oil system and the physicochemical characteristics of the oil. The direct acting hydraulic …

Cloning And Expression Of Heterologous Proteins In Bacteria And Yeast, Urvi J. Desai

All-Inclusive List of Electronic Theses and Dissertations

Heterologous proteins are proteins produced by foreign hosts. The ability to overexpress commercially important proteins in various biological systems has revolutionized the field of biotechnology. In this project three proteins, namely Taq DNA polymerase, E. coli β-galactosidase, and S. cerevisiae topoisomerase I, were cloned and overexpressed in heterologous host. Conventional methods to obtain DNA polymerase from T. aquaticus were cumbersome. Cloning of the gene had been reported but the purification scheme required several steps. To simplify the purification procedure and improve the yield, the DNA polymerase gene from T. aquaticus was cloned into E. coli expression vector pUC18. A single …

This paper presents the first analysis of diffractive photon dissociation events in deep inelastic positron-proton scattering at HERA in which the proton in the final state is detected and its momentum measured. The events are selected by requiring a scattered proton in the ZEUS leading proton spectrometer (LPS) with xL > 0.97, where xL is the fraction of the incoming proton beam momentum carried by the scattered proton. The use of the LPS significantly reduces the contamination from events with diffractive dissociation of the proton into low mass states and allows a direct measurement of t, the square of the four-momentum …

Dijet Cross Sections In Photoproduction At Hera, J. Breitweg, M. Derrick, D. Krakauer, S. Magill, D. Mikunas, B. Musgrave, J. Repond, R. Stanek, R. L. Talaga, R. Yoshida, H. Zhang, Margarita C. K.

Dijet cross sections are presented using photoproduction data obtained with the ZEUS detector during 1994. These measurements represent an extension of previous results, as the higher statistics allow cross sections to be measured at higher jet transverse energy (ETjet). Jets are identified in the hadronic final state using three different algorithms, and the cross sections compared to complete next-to-leading order QCD calculations. Agreement with these calculations is seen for the pseudorapidity dependence of the direct photon events with ETjet > 6 GeV and of the resolved photon events with ETjet > 11 GeV. Calculated cross sections for resolved photon processes with 6 …

Photon diffractive dissociation, γp → Xp, has been studied at HERA with the ZEUS detector using ep interactions where the virtuality Q2 of the exchanged photon is smaller than 0.02 GeV2. The squared four-momentum t exchanged at the proton vertex was determined in the range 0.073 < \t\ < 0.40 GeV2 by measuring the scattered proton in the ZEUS Leading Proton Spectrometer. In the photonproton centre-of-mass energy interval 176 < W < 225 GeV and for masses of the dissociated photon system 4 < Mx < 32 GeV, the t distribution has an exponential shape, dN/d\t\ ∝ exp (-b\t\), with a slope parameter b = 6.8 ± 0.9 (stat.) +1.2-1.1 (syst.) GeV-2.

The shape of jets produced in quasi-real photon-proton collisions at centre-of-mass energies in the range 134-277 GeV has been measured using the hadronic energy flow. The measurement was done with the ZEUS detector at HERA. Jets are identified using a cone algorithm in the η - φ plane with a cone radius of one unit. Measured jet shapes both in inclusive jet and dijet production with transverse energies EjetT > 14 GeV are presented. The jet shape broadens as the jet pseudorapidity (ηjet) increases and narrows as EjetT increases. In dijet photoproduction, the jet shapes have been measured separately for samples …

High-ET Inclusive Jet Cross Sections In Photoproduction At Hera, J. Breitweg, M. Derrick, D. Krakauer, S. Magill, D. Mikunas, B. Musgrave, J. Repond, R. Stanek, R. L. Talaga, R. Yoshida, H.

Inclusive jet differential cross sections for the reaction e+p → e+ + jet + X with quasi-real photons have been measured with the ZEUS detector at HERA. These cross sections are given for the photon-proton centre-of-mass energy interval 134 < W < 277 GeV and jet pseudorapidity in the range -1 < ηjet < 2 in the laboratory frame. The results are presented for three cone radii in the η - φ plane, R = 1.0, 0.7 and 0.5. Measurements of dσ/dηjet above various jet-transverse-energy thresholds up to 25 GeV and in three ranges of W are presented and compared to next-to-leading order (NLO) QCD calculations. For jets defined with R = 1.0 differences between data and NLO calculations are seen at high ηjet and low EjetT. The measured cross sections for jets defined with R = 0.7 are well described by the calculations in the entire measured range ηjet and EjetT. The inclusive jet cross section for EjetT > 21 GeV is consistent with an approximately linear variation with the cone radius R in the range between 0.5 and 1.0, and with NLO calculations.

Elastic And Proton-Dissociative Ρ0 Photoproduction At Hera, J. Breitweg, M. Derrick, D. Krakauer, S. Magill, D. Mikunas, B. Musgrave, J. Repond, R. Stanek, R. L. Talaga, R. Yoshida, H.

Elastic and proton-dissociative ρ0 photoproduction (γp → p0p, γp → ρ0N, respectively, with p0 → π+π-) has been studied in ep interactions at HERA for photon-proton centre-of-mass energies in the range 50 < W < 100 GeV and for |t| < 0.5 GeV2, where t is the square of the four-momentum transfer at the proton vertex; the results on the proton-dissociative reaction are presented for masses of the dissociated proton system in the range M2N < 0.1W2. For the elastic process, the π+π- invariant mass spectrum has been investigated as a function of t. As in fixed target experiments, the ρ0 resonance shape is asymmetric; this asymmetry decreases with increasing |t|, as expected in models in which the asymmetry is ascribed to the interference of resonant and non-resonant π+π- production. The cross section has been studied as a function of W; a fit to the resonant part with the form Wa gives a = 0.16 ± 0.06 (stat.) +0.11-0.15 (syst.). The resonant part of the γp → π+π-p cross section is 11.2 ± 0.1 (stat.) +1.1-1.2 (syst.) μb at 〈W〉 = 71.7 GeV. The t dependence of the cross section can be described by a function of the type Aρ exp (-bρ|t| + cρt2) with bρ = 10.9 ± 0.3 (stat.) +1.0-0.5 (syst.) GeV-2 and cρ = 2.7 ± 0.9 (stat.) +1.9-1.7 (syst.) GeV-4. The t dependence has also been studied as a function of W and a value of the slope of the pomeron trajectory α IP′ = 0.23 ± 0.15 (stat.) +0.10-0.07 (syst.) GeV-2 has been deduced. The ρ0 spin density matrix elements r0400 r041-1 and ℜe[r0410] have been measured and found to be consistent with expectations based on s-channel helicity conservation. For proton-dissociative π+π- photoproduction in the ρ0 mass range, the distributions of the two-pion invariant mass, W and the polar and azimuthal angles of the pions in the helicity frame are the same within errors as those for the elastic process. The t distribution has been fitted to an exponential function with a slope parameter 5.8 ± 0.3 (stat.) ± 0.5 (syst.) GeV-2. The ratio of the elastic to proton-dissociative ρ0 photoproduction cross section is 2.0 ± 0.2 (stat.) ± 0.7 (syst.).

A Systematic Evaluation Of Methods To Separate X- And Y- Bearing Sperm, Jacquelyn Irving

Theses: Doctorates and Masters

This project was initiated to determine if was possible to enrich either X- or Y- bearing sperm, and hence to preselect the sex of a child. Two of the possible reasons why couple might want to select the sex of a child are firstly because of a family history of an X-linked recessive genetic disorder, which usually only affect sons, and secondly families who have had several children of one sex. For this study, men with three or more children of the same sex were recruited following the publication of an article in The West Australian newspaper. The percentage of …

The Role Of Management In The Movement Towards Sustainability: Perceived Responsibilities, Challenges, And Opportunities, Martin Brueckner

Theses: Doctorates and Masters

The aim of this thesis was to explore the role of management in the movement towards ecologically sustainable development (ESD), investigating perceived responsibilities, challenges, and opportunities facing business management today. The point of departure for this study was the acknowledgement of the present paucity of references to ESD within the management literature, widespread amoral business conduct, and the dominance of economic rationalism within business science. This research provided an analytical review of ESD related literature, concentrating on the history and rise of the ESD paradigm, its ethical underpinnings, and economic implications to management practice. The paper highlighted the importance of …
