The Participant's Perception Of The Contribution Of Lyengar Yoga To Their Health And Well-Being, Ann Dragon Jan 1998

The Participant's Perception Of The Contribution Of Lyengar Yoga To Their Health And Well-Being, Ann Dragon

Theses : Honours

To date little research has been conducted to substantiate the many anecdotal claims that yoga improves both physical and mental health. Berger and Owen (1992) demonstrated that yoga practice could enhance mood state. Mind-body exercise modalities, such as tai chi and yoga, potentially offer significant benefit in the areas of exercise rehabilitation and health promotion strategy (LaForge, 1997). Yoga is steadily gaining popularity amongst western culture with an increasing number of people participating in this mind-body exercise modality. Investigating the perceived contribution of regular yoga practice to health and well-being could uncover a number of positive 'indicators towards exercise adherence …

The Effects Of Context And Number Of Presentations On Repetition Priming, Terry A. Simpson Jan 1998

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 …

Women On The Move: A Qualitative Study Of Relocation To A Remote Area, Ann Jones Jan 1998

Women On The Move: A Qualitative Study Of Relocation To A Remote Area, Ann Jones

Theses : Honours

This study uses a feminist framework to explore women's experiences of relocating from a city or large regional centre to a small and isolated town. It comes in response to my personal and professional experience of remote relocation and to the dearth of feminist discussion in this area. The site of the study is a town of 2,500 people, situated in Northern Australia over 1200 kilometres from the nearest capital city and 800 kilometres from the nearest regional centre. Six women who relocated within the previous 18 months participated in the study. Two of the women were single and four …

Reefs As Contributors To The Diversity Of Epiphytic Algal Communities In Seagrass Meadows, B. R. Van Elvan Jan 1998

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 …

Bright Lights, Small City: New Beginnings Of The Singapore Film Industry, Samantha W.M. Tan Jan 1998

Bright Lights, Small City: New Beginnings Of The Singapore Film Industry, Samantha W.M. Tan

Theses : Honours

The Singapore government decided in J9H5 that making movies and turning the country into a regional film centre was an ideal venture to help develop and sustain the country's economic growth. The nation has about 3.7 million people, and although English is studied as the first language, about half of the population (especially the older generation) are more well-versed in their mother tongue, ie. Chinese, Malay or Tamil. Because of this disparity, it would appear that the Singapore market doesn't have the critical mass to sustain a film industry unless the movies are made for export. Little has been written …

Behaviour Of Gilbert's Potoroo (Potorous Gilbertii Gould) In Captivity, Kylie Dijon Burke Jan 1998

Behaviour Of Gilbert's Potoroo (Potorous Gilbertii Gould) In Captivity, Kylie Dijon Burke

Theses : Honours

In late 1994, Gilbert's Potoroo was rediscovered almost 120 years after it was believed to have become extinct. It was found at Two Peoples Bay Nature Reserve, near Albany, Western Australia. Since then, it has become urgent that detailed studies of the potoroo's behaviour and ecology be undertaken, so as to increase the understanding of the needs of 'this critically endangered marsupial. Due to its critical status, increasing the number of animals is of paramount importance to the continued survival of this species. An understanding of the behavioural repertoire of the species will aid in its recovery and provide the …

Comparison Of Median Indicator Kriging With Full Indicator Kriging In The Analysis Of Spatial Data, Donna Hill Jan 1998

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 …

The Soil Acarine Fauna Of Selected Agroecosystems Within The York Shire, Derek Juan Swarts Jan 1998

The Soil Acarine Fauna Of Selected Agroecosystems Within The York Shire, Derek Juan Swarts

Theses : Honours

The practice of broadacre, dryland farming is known to affect the physico-chemical structure of the soil but our knowledge or its impact on the biological structure is rudimentary. The soil acarine (mite) communities which inhabit these soils display a variety of responses to this agricultural practice. With the increasing focus on developing ecologically sustainable agricultural techniques, an understanding of the soil acari becomes increasingly important. This study investigated the impact of two agricultural practices (designated here us Conventional and Non-Conventional) upon the abundance and diversity of the soil acari. Conventional agricultural practice involved broad scale chemical application to weeds and …

Behavioural Contexts For The Expression Of Modern Racism: The Simulated Juror Paradigm, Murray Riggs Jan 1998

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 Jan 1998

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) …

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 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.

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.).

Retention Of Administrators In Nursing Homes: What Can Management Do?, Douglas A. Singh, Robert C. Schwab Jan 1998

Retention Of Administrators In Nursing Homes: What Can Management Do?, Douglas A. Singh, Robert C. Schwab

Faculty Publications

Annual turnover among nursing home administrators may be 40% or higher. To investigate the factors that could lead to greater administrator retention, responses to a survey (53% response rate) were analyzed using factor analysis and multiple regression models. Results show that higher retention is observed when administrators are allowed to function independently, are involved in decision making, are treated fairly, and are given reasonable goals to achieve. Organizations must hire administrators whose values match theirs. Multifacility chain organizations and for-profit facilities appear to have a greater need to embrace organizational principles that lead to greater job satisfaction.
