Press Independence In Newspaper Coverage Of The 2009 Health Care Debate, Matthew Holt Barnidge

LSU Master's Theses

This study examines press independence from the government in the 2009 national health care debate. Through a content analysis examining source expressions, or the words journalists attribute to various people in the news, the study captures the essence of the discourse represented in the news about the debate. This paper also outlines a distinction between various types of autonomy, and offers a new conceptualization of independence. Procedural autonomy, which is autonomy in journalistic norms and routines, does not necessarily result in content autonomy, which is autonomy of viewpoints expressed in the news. In other words, if non-governmental sources say substantially …

Laser-Assisted Zona Pellucida Hatching Of Frozen-Thawed In Vivo-Produced Bovine Embryos, Mindy Kaye Chiasson

LSU Master's Theses

Incomplete zona hatching or failure of the zona to rupture compromises post-transfer embryo viability and conceptus development. Assisted hatching prior to the transfer of frozen-thawed bovine embryos has been proposed as a means to increase recipient pregnancy rates. The objective of this study was to determine if laser-assisted hatching would improve in vivo-produced frozen-thawed bovine embryo hatching and pregnancy rates. In Experiment I,II and III frozen direct-transfer embryos received either two a or three symmetrical rents at either 40% or 80% through the outer zona surface using the Hamilton Thorne XYClone® (Hamilton Thorne Biosciences) diode laser at 90% power with …

Antisense Silver Nanoparticles For Photo-Activated Gene Silencing, Paige Kathleen Brown

LSU Master's Theses

The unique properties of noble metal nanoparticles, which include tunable electronic and photonic characteristics, contribute to their potential as novel delivery vectors with enhanced drug stability, cell uptake, and photo-activated functionalities. Silver, as one of best surface-enhancing substrates available for bulk nanostructure synthesis, is a prime choice for investigations of metal nanohybrids as antisense therapy vehicles with special surface plasmon resonance (SPR) enabled functional attributes. The singular photonic properties of silver nanoparticles (SNPs) may contribute to ease of delivery confirmation and in situ photo-activation of protected cargo packed on particle surfaces. Here we show the synthesis and characterization of 40-80nm …

Ephemeral Media, Persistent Action: Public Pedagogies Of Collective Resistance, Jessica Ketcham Weber

LSU Doctoral Dissertations

In Ephemeral Media, Persistent Action: Public Pedagogies of Collective Resistance, I argue that representations of contemporary activism against corporate globalization, as analyzed in three different sites of commercially-driven media texts—newspapers, film, and websites—teach people to move away from public forms of collective activism and towards privatized and institutionally-sponsored forms as part of the larger project of neoliberalism. Specifically, this dissertation focuses on the representations of, and responses to the representations of, two events—the protests against the World Trade Organization Ministerial Conference in Seattle, Washington in 1999 and the protests during the Republican National Convention in 2004 in New York City—as …

An Exploratory Study On The Perspectives Of Western Australian Drivers Towards Responding To Emergency Vehicles, Pauline Grant

Theses : Honours

Failing to give way to emergency vehicles has resulted in one crash per day on Australian roads (NRMA, 2009), and delayed emergency service responses to situations that constitute a serious threat to life and/or property. With an anticipated population increase in Western Australia (ABS, 2009) this problem will only worsen. Whilst there have been attempts to address the problem through information leaflets and media campaigns, the success of such initiatives is not clear because of a lack of empirical assessment. The little research available in the area, focused on crash scenarios, emergency vehicle drivers, or other non-psychological processes. The current …

Experiences And Perceptions Of How Community-Based Interventions Can Promote Young Adults' Resilience To Suicide Within Rural/Regional Communities, Tracy Evans

Theses : Honours

In the literature, both statistics and studies have noted that suicide in rural/regional young adults' is an important concern. Recent research suggests, that to facilitate a primary approach to suicide prevention in young people, there is a need to promote the protective construct of resilience at a community level, highlighting strategies such as connectedness, and decreasing the stigma related to mental illness and health-seeking behaviour (Commonwealth Department of Health & Aged Care, 2005; Injury Control Council of Western Australia, 2006). However, there is a need to investigate and identify the links or mediating factors that promote individual resilience within a …

To investigate this affect and treatment gap, a mixed-methods revelatory single-case design, built on evidence-based treatment elements was designed and tested. Solo pianist, David Helfgott rated, performed and provided musical performances by Louis Moreau Gottschalk and Claude Debussy which were listened to once each morning before school by a 10-year-old female with AD. Anxiety was recorded via a self-report Daily Journal and parent-report Spence Child Anxiety Scale for 20 consecutive school days. Results indicated support for the …

Resilience In Families With Same-Sex Parents, Natasha Griffiths

Theses : Honours

Research suggests resilience can be viewed as a dynamic process facilitating positive functioning within the context of significant adversity. A nuclear family type that remains a controversial and stigmatized group is families with same-sex parents. Same-sex families face a great number of challenges, due to the presence of heterosexism in society and they are often heavily criticised within the broad public domain. The current study adopted a phenomenological methodology to identify the family resilience processes utilised by same-sex families. Five lesbian couples (n = 10) raising children in Perth, Western Australia were interviewed. A thematic analysis technique outlined by Glesne …

A purposive sample of thirteen young men, 25 to 30 years of age, living in urban areas of Perth, were interviewed using in-depth, semi-structured interviews. The ultimate aim of this study was to discover meaning and enhance the understanding of the essential experiences that influence help-seeking behaviours of these young men. The findings of this inquiry indicate a sophisticated emotional discourse …

The Impact Of Crime Outcomes On Public Opinions On Sentencing: In Particular Regards To Recent "One Punch" Legislation, Teneke Kuek

Theses : Honours

Australia has recently experienced a punitive swing in sentencing policies and legislation. Consequently, politicians have responded favourably to popular demands for harsher sentencing. A comprehensive review of the current literature has been undertaken to understand why the community has adopted such a punitive position. It has been suggested that the media have hypersensitised the public into believing that crime is much more prevalent than it actually is, resulting in the individual fearing becoming a victim of crime. The public then chooses to elect politicians who appear to be concerned with their safety and the associated legislation. Expectancy/value theory contends that …

From Junior To Senior Sport: Do Athletes Differ In Their Transitional Experiences?, Glen Ewen

One hundred and forty eight male and female elite athletes aged between 14 and 18 years, from a variety of sports in both city and country locations of Western Australia, were surveyed. Two test instruments were used; the newly developed Swedish, Transitional Monitoring Survey (TMS), and the Athletic Identity Measurement Scales (AIMS). Univariate descriptive statistics, One Way Analysis of Variance (ANOVA), and reliability measures were used to analyse …

Forty Years Of Movie Hacking: Considering The Potential Implications Of The Popular Media Representation Of Computer Hackers From 1968 To 2008, Damian Gordon

Articles

Increasingly movies are being produced which feature plots that incorporate elements of computer security and hacking, and cumulatively these movies are creating a public perception as to the nature of computer security. This research examines movies that feature hackers (and hacking) to identify if any common themes emerge from these movies in their representation of these issues. To achieve this, first a corpus of hacking movies is created, and then using a qualitative data analysis technique, guidelines are developed which distinguish those movies that actually have the potential to create a perception with the general public. The resultant dataset is …

Synthesis And Characterization Of Metal Decorated Bamboo Structured Carbon Nanotubes For Hydrogen Storage, Sean Charles Mickey

Doctoral Dissertations

"Although hydrogen has been considered as a viable alternative fuel, the storage systems used to contain the hydrogen must be improved for large scale use. A variety of conceivable storage options exist ranging from compressed gas, cryogenic liquid, chemical solid state storage, and adsorptive surfaces. Carbon nanotubes (CNTs) provide a potentially viable option for hydrogen storage applications as a high surface area, lightweight media for adsorptive storage, but do not efficiently store hydrogen at ambient temperatures. Metal hydrides, on the other hand, are able to store large weight percents of hydrogen in a chemical solid state, but generally have unfavorable …

Sintering And Microstructural Effects On Mechanical Properties Of Zirconium Carbide-Tungsten Cermets, Melissa M. Giles Craft

Masters Theses

"Zirconium carbide-tungsten cermets were prepared by in situ reaction sintering a mixture of zirconia and tungsten carbide. Tungsten is a refractory metal with a melting point of 3422⁰C; however, its mechanical strength decreases significantly with increasing temperature. One approach to improve the elevated temperature strength is to add ceramic particulates to the matrix. Zirconia and tungsten carbide were compacted and then reacted and sintered in a single step by heating to 2050⁰C. The resulting stoichiometric zirconium carbide-tungsten cermet had a relative density greater than 96%. Cermets with two different grain sizes were produced by altering the final sintering temperature. Sintering …
