Resilient Optical Multicasting Utilizing Cycles In Wdm Optical Networks, Abhishek Satyedranath Jan 2006

Resilient Optical Multicasting Utilizing Cycles In Wdm Optical Networks, Abhishek Satyedranath

LSU Master's Theses

High capacity telecommunications of today is possible only because of the presence of optical networks. At the heart of an optical network is an optical fiber whose data carrying capabilities are unparalleled. Multicasting is a form of communication in wavelength division multiplexed (WDM) networks that involves one source and multiple destinations. Light trees, which employ light splitting at various nodes, are used to deliver data to multiple destinations. A fiber cut has been estimated to occur, on an average, once every four days by TEN, a pan-European carrier network. This thesis presents algorithms to make multicast sessions survivable against component …

Evaluation Of An Amperometric Biosensor For The Detection Of Escherichia Coli O157:H7, Danyelle Denise Small Jan 2006

Evaluation Of An Amperometric Biosensor For The Detection Of Escherichia Coli O157:H7, Danyelle Denise Small

LSU Master's Theses

Escherichia coli O157:H7 contamination is a major hazard in the water supply, causing outbreaks of disease. Conventional methods of E. coli O157:H7 detection usually takes 1-2 days and require hands-on preparation. There is a need to develop a rapid, inexpensive means of detecting the organism. The amperometric biosensor technology has achieved success in the area of metabolite detection. In this study, a bench scale amperometric biosensor was investigated to rapidly detect Escherichia coli O157:H7. The amperometric biosensor consisted of a power source, Clark electrode, autoranging picoammeter, and fabricated polyvinyl chloride (PVC) outer insert with nitrocellulose membrane and attached horseradish peroxidase …

Association Genetics For Agronomic Traits In Rice And Cloning Of Als Herbicide Resistant Genes From Coreopsis Tinctoria Nutt, Nengyi Zhang Jan 2006

Association Genetics For Agronomic Traits In Rice And Cloning Of Als Herbicide Resistant Genes From Coreopsis Tinctoria Nutt, Nengyi Zhang

LSU Doctoral Dissertations

We have evaluated the potential of discriminant analysis (DA) to detect candidate markers associated with twelve economically important traits in a large population of unrelated U.S. and Asian inbred lines of rice. Associated marker alleles detected by DA mapped within the same genetic intervals when compared with previous traditional QTL mapping experiments that evaluated progeny derived from various controlled crosses. New markers identified by DA suggest that the procedure can also uncover relevant genetic regions not possible by standard genetic tests. With the same dataset, we also compared different modern regression approaches for selecting molecular markers associated with the twelve …

Measuring Player Perceptions Of Advertising In Online Games, Ben Lewis Jan 2006

Measuring Player Perceptions Of Advertising In Online Games, Ben Lewis

LSU Master's Theses

An experiment with 100 participants aged 18-24 was conducted to measure the effects of advertising in an online role-playing computer game on perceived interactivity and other aspects of gameplay experience. Results from a post-test questionnaire revealed insight into players' attitudes toward advertising in video game environments, and reflected varying levels of advertising awareness and recall, message recognition, and factors in purchasing habits. Results suggested that while advertising in online games can sometimes trigger high advertising awareness rates, it can also reduce a game's perceived sense of realism and genuinely annoy players if not appropriately coordinated with the game environment. Whereas …

Why Undergraduate Nurses Choose Not To Pursue Mental Health Nursing As A Career In Western Australia : A Descriptive Study, Therese Howell Jan 2006

Why Undergraduate Nurses Choose Not To Pursue Mental Health Nursing As A Career In Western Australia : A Descriptive Study, Therese Howell

Theses : Honours

Not only are fewer undergraduate nursing students opting to pursue a career in mental health nursing (Arnswald, 1987; Clinton & Hazelton, 2000; Happell, 1998; Lam, McMaster & Troup, 1993), but nursing students continue to rank mental health nursing as their lowest preference of career choice. Instead, nursing undergraduates appear to be opting for positions within the surgical or critical care specialties (Durkin, 2002; Happell, 1999; Happell1999; Happell, 2001). The aim of this descriptive study was to investigate and identify the potential reasons why undergraduate nursing students do not take up mental health nursing as a career. This descriptive study implemented …

Enrolled Nurses' Attitudes, Subjective Norms, Intentions And Behaviour Related To Independent Medication Administration, Donna Sayers Jan 2006

Enrolled Nurses' Attitudes, Subjective Norms, Intentions And Behaviour Related To Independent Medication Administration, Donna Sayers

Theses : Honours

The purpose of this quantitative descriptive research study was to investigate Enrolled Nurses' attitudes, intentions and behaviour in relation to independent medication administration (IMA). This research was necessary as a significant number of Enrolled Nurses (ENs) are now able to administer medications up to Schedule Four level, without supervision when they have completed a medication administration programme (MAP). This change in the scope of practice for the EN will eventually be introduced nationally as recommended by the National Review of Nursing Education (2002). Anecdotal reports suggest that IMA is causing concern for the EN but little or no research has …

The Relationship Between Body Image And Self-Esteem In Older Adulthood, Lucie Guegan Jan 2006

The Relationship Between Body Image And Self-Esteem In Older Adulthood, Lucie Guegan

Theses : Honours

Purpose: Given the global trend of population ageing and the fact that Australia will experience a significant increase in the proportion of older adults, research into ageing issues has become a National priority. Whilst body image and self-esteem have been empirically linked, the relationship among older adults has been neglected. The present study investigated several body image variables and their relationship to self-esteem in a sample of older adults. Design and Methods: Questionnaires consisting of the Rosenberg Self-Esteem Scale and the Multidimensional Body-Self Relations Questionnaire were administered to 148 adults aged between 65 and 85 years, living independently in the …

Pollen Characteristics Of Grevillea Species Determined By In Vitro Germination, Rebecca Parsons Jan 2006

Pollen Characteristics Of Grevillea Species Determined By In Vitro Germination, Rebecca Parsons

Theses : Honours

Germination of pollen in vitro is a common technique used to assess the ability of pollen to germinate under a variety of conditions. The ability to determine the viability of a pollen grain, and optimal conditions for maximum germination and storage are important for hybridisation. A means of storing pollen, while maintaining viability, enables inter-species hybridisation between species that are spatially and temporally (flowering time) separated. The ultimate aim of hybridisation is seed set and in order to increase this in a genus renowned for a very low fruit to flower ratio, maximum pollen germination must be obtained. Therefore, by …

The Experience Of The Transition To An Aged-Care Facility: A Qualitative Exploration, Jenny M. Smith Jan 2006

The Experience Of The Transition To An Aged-Care Facility: A Qualitative Exploration, Jenny M. Smith

Theses : Honours

The transition from one's place of residence to an aged-care facility may be a daunting prospect, with many factors relevant to the degree of ease in which this change occurs. Whilst this is a significant life event, qualified information about older adults' experience of it is limited, with little found about Australia. Much of what is available focuses on the caregivers' and relatives' viewpoints or their interactions with staff and do not pertain to the transition period itself, but to aged care in general. The main findings from the available literature suggest that the way a new resident perceives their …

Natural Death In The West Australian Newspaper, Heinrich Benz Jan 2006

Natural Death In The West Australian Newspaper, Heinrich Benz

Theses : Honours

This thesis analyses the way The West Australian presents natural death to its readers. Previous research involving death notices and obituaries has focused on gender and numerical analysis. There are hundreds of books dealing with death, covering legal, biological, physical, sociological and spiritual aspects of death, but books on death in the media tend to skirt around natural death. The diverse areas of death research fail to postulate a common definition of natural death. A similar diversity of views exists on the good death and the concepts surrounding life after death. This encourages the analysis of material from daily life, …

Electoral Professionalism And The 2004 Australian Federal Election Campaign, Ryan Boyd Jan 2006

Electoral Professionalism And The 2004 Australian Federal Election Campaign, Ryan Boyd

Theses : Honours

Electoral professionalism, a. term first coined by Panebianco (1988), explains the changing organisational structure of modern political parties and changes to the way parties engage with the electorate. This thesis demonstrates the extent to which electoral professionalism was prevalent during the 2004 Australian federal election campaign. Australian democracy has undergone a process of professionalisation in recent decades. The Liberal Party and the Labor Party's ability to adapt to these changes has enabled Australia's two major parties to remain relevant and come to dominate Australia's political system. Campaign professionals skilled in areas such as polling, marketing, media management, computer technologies, direct …

The White Death: Representations Of Salt Affected Landscapes In The Wheatbelt, Grant Currall Jan 2006

The White Death: Representations Of Salt Affected Landscapes In The Wheatbelt, Grant Currall

Theses : Honours

This exegesis examines the significance of salt-affected landscapes in Western Australia's Wheatbelt, particularly sites affected due to pastoral settlement. It explores ways in which landscape imagery has been constructed and controlled by cultures to represent a particular relationship between settlement and the land. A focus on both American and Australian photographic practitioners and their understanding of landscape aesthetics will be incorporated to reveal how unconventional subject matter like dryland salinity can be re-presented to provide an alternative perspective of cultures relationship with nature in the Wheatbelt. Finally, an enquiry into the impact of national identity on landscape will also explore …

Hogarth To Monster Wheels : A Grotesque Connection, Christopher Ridley Jan 2006

Hogarth To Monster Wheels : A Grotesque Connection, Christopher Ridley

Theses : Honours

When an audience is exposed to deformed, altered and abnormal entities, their interpretation relies on some form of cultural awareness of both the expected and the altered shape to stimulate a reaction. I maintain that the stimulus for this reaction has its roots in a dark and terrifying primal force, the manifestation of which we regard as the grotesque. This thesis looks for a commonality in a satirical interpretation afforded to this grotesque force. By using the caricatures in William Hogarth's engravings and the altered cars in three contemporary films. I search for a correlation between the way Hogarth and …

The Filmmaker, The Subject And The Audience : A Dialectical Exploration Of Documentary Performance, Ben Stewart Jan 2006

The Filmmaker, The Subject And The Audience : A Dialectical Exploration Of Documentary Performance, Ben Stewart

Theses : Honours

Documentary filmmakers 11 engage directly in the study of the phenomena of life that surrounds us. We hold the ability to show and elucidate life as it is, considerably higher than the occasionally diverting droll games that people call theatre, cinema etc." (Vertov, 1984, p. 47). The ability to 'show and elucidate life as it is' is a controversial claim that the majority of academic documentary discussion is concerned with. I intend to add to this discussion through an exploration of performance and its pertinence to the ability of documentary to represent reality truthfully. The reception of documentary is significantly …

Cyberactivism : Public Relations In A Wired World, Shane Newton Jan 2006

Cyberactivism : Public Relations In A Wired World, Shane Newton

Theses : Honours

Computer-mediated communication has revolutionised the way activist groups influence the opinion of corporations, governments and the community. It has never been so cheap or convenient to publish high-quality material to push a specific issue or cause. Activists are no longer restricted to satisfy the news values of media corporations to reach wide publics. Nor do these businesses (or governments) have any apparent advantage, despite their more economically sustainable and highly-resourced positions. Current literature is able to examine and explore how the Internet is used and the problems involved, yet much research fails to examine how these constraints and opportunities are …

Tacticians, Talent, Transmitters And Targets : The Power Of Pictures In The Howard Prime Ministership, Richard Goodwin Jan 2006

Tacticians, Talent, Transmitters And Targets : The Power Of Pictures In The Howard Prime Ministership, Richard Goodwin

Theses : Honours

After a decade as Prime Minister of Australia, John Howard has attained a substantial place in the nation's political history. His success can be measured in numerous ways: four successive victories for his Liberal National Party Coalition in general elections since 1996, five opponents in turn at the head of the rival Australian Labor Party and consistently high approval ratings in opinion polls for his performance as prime minister. He has also dominated the political discourse of Australia. His views and policy positions have become progressively entrenched. This is especially true in the areas of international affairs, military engagement and …

Death Lilly : Performing The 'Flower Girl' Role In The Age Of Consumption, Catherine Gomersall Jan 2006

Death Lilly : Performing The 'Flower Girl' Role In The Age Of Consumption, Catherine Gomersall

Theses : Honours

This self-reflexive photomedia project interrogates the 'flower girl' role as a cultural fetishism of 'innocent' white-girl femininity, which I claim is perpetuated in the bridal fantasy. In my photomedia work the theme of 'death' and the uncanny is explored as well as the themes of 'wildness' and 'violence' in order to subvert the dominant discourse of ideal white femininity which is defined in popular culture by a sanitised bourgeois aesthetic. I attack the bourgeois surface of the bridal magazine in my artwork as I perform the 'flower girl' role in the context of popular culture and capitalism. The flower girl …

The Distribution Of Diatom Flora In Ice Caves Of The Northern Yukon Territory, Canada: Relationship To Air Circulation And Freezing, Bernard Lauriol, Clément Prévost, Denis Lacelle Jan 2006

The Distribution Of Diatom Flora In Ice Caves Of The Northern Yukon Territory, Canada: Relationship To Air Circulation And Freezing, Bernard Lauriol, Clément Prévost, Denis Lacelle

International Journal of Speleology

In the late 1980’s and early 1990’s, various media in karst environments in the Northern Yukon Territory were examined for their diatom content. Cryogenic cave calcite powders, grus and various ice formations (ice plugs, ice stalagmites and floor ice) were collected from three freezing caves and one slope cave to make an inventory of the diatom content, and to explain the spatial distribution of the diatoms within the caves. The results show that approximately 20% of diatoms in the caves originate from external biotopes and habitats (e.g., river, lake, stream), with the remaining 80% of local origin (i.e., from subaerial …
