An Experimental Study Into The Effect Of Varying The Join Selectivity Factor On The Performance Of Join Methods In Relational Databases, Ada Mallet Jan 1998

An Experimental Study Into The Effect Of Varying The Join Selectivity Factor On The Performance Of Join Methods In Relational Databases, Ada Mallet

Theses : Honours

Relational database systems use join queries to retrieve data from two relations. Several join methods can be used to execute these queries. This study investigated the effect of varying join selectivity factors on the performance of the join methods. Experiments using the ORACLE environment were set up to measure the performance of three join methods: nested loop join, sort merge join and hash join. The performance was measured in terms of total elapsed time, CPU time and the number of I/O reads. The study found that the hash join performs better than the nested loop and the sort merge under …

Sequential Testing Effects Re-Visited : Is The Effect Of Test Presentation Contingent Upon Slide Linearity?, John D. Jones Jan 1998

Sequential Testing Effects Re-Visited : Is The Effect Of Test Presentation Contingent Upon Slide Linearity?, John D. Jones

Theses : Honours

Evidence regarding the potential mediating effects sequential test presentation has upon eyewitness suggestibility is divided. Bekerian and Bowers' (1983) research suggested that sequential test presentation reduced misinformation effects, whilst McCloskey and Zaragoza's (1985) results failed to indicate any effect of this presentation method. A possible reason for these conflicting results is that the respective research groups have used different sets of slides. Bekerian and Bowers' (1983) slides appeared to contain more thematic content (i.e., linear content), which in turn increased participants' resistance to misleading postevent information. Conversely, McCloskey and Zaragoza's (1985) slides appeared to lack this feature (i.e., they are …

Testing The Matching Hypothesis : Implementing A Minimal Stress Intervention By Matching Writing Task To Emotional Coping Style, Pamela D. Mcneill Jan 1998

Testing The Matching Hypothesis : Implementing A Minimal Stress Intervention By Matching Writing Task To Emotional Coping Style, Pamela D. Mcneill

Theses : Honours

The theory of inhibition and psychosomatic disease supports the concept that failure to express emotion is psychologically and physically stressful, and associated with long-term health problems. One aspect of this study was to investigate the discrepancy hypothesis proposing that specific emotional coping styles elicit patterns of discrepant self-report and physiological responses. The major focus of the study tested whether matching therapeutic writing tasks to specific emotional coping styles would significantly decrease stress and somatic symptoms, and whether mismatching such writing tasks to emotional coping styles would not decrease stress and somatic symptoms. Undergraduate students were identified as having an emotional …

Skill Acquisition And Transfer : The Effect Of Practice On Performance, Tracy Piani Jan 1998

Skill Acquisition And Transfer : The Effect Of Practice On Performance, Tracy Piani

Theses : Honours

This study was designed to examine the effect of amount of training on the specificity of skill acquisition and transfer. Within the theoretical framework of two contemporary theories of skill acquisition, Anderson's ACT" theory (1982, 1987), and Logan's Instance theory of automisation (1988, 1990), the study extends research by Greig and Speelman (in press) that demonstrated skills can be both general (i.e., can apply beyond the training experience) and specific (i.e., are limited to training experiences). The experiment was divided into training and transfer phases. The amount of practice in the training phase was manipulated across three experimental conditions, with …

Gaas Implementation Of Fir Filter, Anup Savla Jan 1998

Gaas Implementation Of Fir Filter, Anup Savla

Theses : Honours

This thesis discusses the findings of the final year project involving Gallium Arsenide implementation of a triangular FIR filter to perform discrete wavelet transforms. The overall characteristics of Gallium Arsenide technology- its construction, behaviour and electrical charactersitics as they apply to VLSI technology - were investigated in this project. In depth understanding of its architecture is required to be able to understand the various design techniques employed. A comparison of Silicon and GaAs performance and other characteristics has also been made to fully justify the choice of this material for system implementation.

Exclusion Mapping Of Polycystic Kidney Disease: A Third Locus, Eoin Thompson Jan 1998

Exclusion Mapping Of Polycystic Kidney Disease: A Third Locus, Eoin Thompson

Theses: Doctorates and Masters

The aim of this research was to perform exclusion on a rare form of hereditary autosomal dominant polycystic kidney disease (ADPKD). To-date, two genes for ADPKD have been identified: PKDI which has been localized to the short arm of chromosome 16 and PKD2 which has been localized to the long arm of chromosome 4. However, a small number of families have been reported that have not shown linkage to either of these two loci, thus suggesting the existence of at least one additional locus (PKD3). Two families that are affected with ADPKD and do not show linkage to PKDI or …

Using Multimedia Microworlds To Motivate And Engage Adult Learners, Susan B. Stoney Jan 1998

Using Multimedia Microworlds To Motivate And Engage Adult Learners, Susan B. Stoney

Theses: Doctorates and Masters

As educational institutions come under increasing pressure from outside forces to restructure the way students learn, efforts are being made by researchers to find ways to assist students to learn through independent thought and to solve problems in a resource-based, self-paced environment. Such an environment needs to be sufficiently interesting and novel to motivate students who begin to use it, and to continue to engage them as they progress through it. This study has sought to identify what such a learning environment needs to encompass in order to motivate and engage adult learners so that they will not only want …

Professional Development And Practice: A Study Of Early Childhood Teachers Of Mathematics, Wendy Hawthorne Jan 1998

Professional Development And Practice: A Study Of Early Childhood Teachers Of Mathematics, Wendy Hawthorne

Theses: Doctorates and Masters

In the past twenty years there has been increased interest in the ways in which teachers construct their professional lives. It is no longer assumed that preservice education alone will enable teachers to meet the challenges of their teaching lives. Ongoing professional development is seen as an essential component of contemporary teachers' lives but remains a challenge for professional development planners and providers. The nature and extent of teachers' participation in professional development was a significant dimension of the investigation of professional development contained in this thesis. The research questions which formed the basis for the data collection in this …

Stakeholders' Voices : A Socio-Cultural Approach To Describing And Extending An Understanding Of Primary Education In Mauritius, Michelle Griffiths

Theses: Doctorates and Masters

This study describes and expands an understanding of primary education in one developing country, Mauritius. The need for the study was argued from a review of literature which brought to notice the lack of social action perspectives in analysis of education in and about developing countries and the necessity and importance of knowing about the reality of schooling in developing countries. The research was conceptualised as a socio-cultural approach. It gave analytical priority to the actions, experiences and perceptions of teachers, pupils, parents and educationists in order to create an account of what Mauritian education was like and meant to …

Developing Performance Support Systems For Complex Tasks: Lessons From A Lesson Planning System, Martyn Wild Jan 1998

Developing Performance Support Systems For Complex Tasks: Lessons From A Lesson Planning System, Martyn Wild

Theses: Doctorates and Masters

There lacks coherent and persuasive rationales for the further development of computer-based, interactive educational materials, for tertiary settings. Indeed, educational software arising out of what might be coined the “multimedia era”, namely the mid and later 19902, has been marked by lacklustre products with an emphasis in development and evaluation placed largely on technological issues (such as the use of video, sound and animations). As such, the rapid increase in commercially available (usually CD based) products has generally met a cool adoption from academics and educationalists, with both these groups often bemoaning the paucity or non-existence of effective instructional design …

Predictability Of Everyday Task Performance By Perceived Health, Self-Efficacy And Cognitive Ability, Joan Klinger Jan 1998

Predictability Of Everyday Task Performance By Perceived Health, Self-Efficacy And Cognitive Ability, Joan Klinger

Theses: Doctorates and Masters

This exploratory research investigated the relationship between a brief neuropsychological measure and everyday functional ability in older community dwelling adults. The association between these two areas is complex, as a specific functional domain often involves several of the cognitive skills typically assessed by a neuropsychological instrument. Whilst there is an extensive literature linking neuropyschological tests to everyday functioning in cognitively impaired older adults, little research has been directed at investigating the relationship between cognitive test performance and everyday competence in non-dementing older people who reside independently in the community. A brief cognitive instrument able to predict coping deficits in instrumental …

Women's Perceptions Of Birth Centre Care: A Qualitative Approach, Karen Coyle Jan 1998

Women's Perceptions Of Birth Centre Care: A Qualitative Approach, Karen Coyle

Theses: Doctorates and Masters

The purpose of this exploratory study was to describe women's perceptions of the care they received in a birth centre, compared to their previous experiences in a hospital. Australian statistics indicate that five percent of childbearing women now choose to receive care in a birth centre setting. Clinical outcomes of birth centre care are now well documented, but there is limited empirical data about women's experiences of this model of care. Seventeen women, who had recently given birth in a birth centre, and had previously experienced care in a hospital setting, were interviewed about their care experiences. Using content analysis, …

Parametric Software Project Estimating: An Analysis Of Current Practice, Stuart Hope Jan 1998

Parametric Software Project Estimating: An Analysis Of Current Practice, Stuart Hope

Theses: Doctorates and Masters

As society and the world economy moves into the second millennium. the service industries involving knowledge workers will continue to increase. Software is the enabling technology that is driving the knowledge industry. As the development of software is mostly a design process, where new artefacts are conceived and built, the prediction of outcomes in the process is fraught with difficulties. Software project estimating is one of the essential Software Engineering techniques that will enable the rationalisation of decision-making regarding software development. Estimates that are more accurate will increase the probability of success and lower the risk. This thesis analyses the …

Fitness To Stand Trial In Australia: The Investigation And Comparison Of Clinical Opinion And Legal Criteria, Miranda P. Hogg Jan 1998

Fitness To Stand Trial In Australia: The Investigation And Comparison Of Clinical Opinion And Legal Criteria, Miranda P. Hogg

Theses: Doctorates and Masters

The extent to which Australian psychologists and psychiatrists are cognisant of the legal standard for Fitness to Stand Trial (FST) was investigated. 198 psychologists from The Australian Psychological Society (APS), and 125 psychiatrists from The Royal Australian and New Zealand College of Psychiatrists (RANZCP) responded to a survey. Psychiatrists identified a greater number of legal criteria than psychologists. This finding extended across clinicians who had experience in the evaluation of fitness to stand trial and those who did not. No difference was found between psychologists and psychiatrists for mentioning irrelevant or insufficient considerations. However, a within-group analysis revealed that the …

"Hades" - A Remarkable Cave On Oldoinyo Lengai In The East African Rift Valley, Gordon J. Davies

International Journal of Speleology

Oldoinyo Lengai is the world’s only active carbonatite volcano, situated in northern Tanzania within the Eastern Rift Valley, al 2.751 degrees S, 35.902 degrees E. It forms an isolated symmetrical cone at the southern end of Lake Natron, with a summit elevation of 2,890 m (9,480 ft). Periodic eruptions of ash and lava have been recorded since about 1880, and with increasing precision during this century since 1904. In 1990 a routine expedition to monitor activity levels at the summit led to the discovery of a remarkable cave located in the crater floor, filled with numerous long delicate pale yellow …

Tectonic Caves Of Solai In The Kenyan Rift Valley, Robert A. Davis Jan 1998

Tectonic Caves Of Solai In The Kenyan Rift Valley, Robert A. Davis

International Journal of Speleology

Tectonic caves at Solai, Kenya, were explored in 1970. These lie in a complex geological area of the Great Rift Valley in columnar-faulted ignimbrite. Fissures are presumed to have been widened by later tectonic activity -e.g. the major earthquake of January, 1928. The caves and exploration are briefly described. Questions of formation, drainage and possibilities of steam reservoirs are discussed.
