Different Approaches To Investigatory Journalism In The Muckraking Era, Tim Vest Klein

LSU Master's Theses

The muckraking era is seen as a golden age of investigatory journalism. This thesis argues that within the muckraking era, there were a number of distinct types of journalism. To understand the muckrakers, we must recognize these different types of investigatory journalism and the potential influence the different types of storytelling can have on public opinion. Fourteen of the preeminent muckrakers are analyzed based on their most important investigatory journalism articles

The Production Of Marketable Vegetable Transplants Using Sustainable Locally Sourced Soilless Media Amendments, Amber Dawn Parker

LSU Master's Theses

Public demand for sustainable local and organic food products has led these systems to become one of the fastest growing sectors in the agricultural food market. Consumers are willing to pay a premium for food produced using organic or sustainable practices. Local and small-scale farmers are striving to develop sustainable and in some cases USDA certified organic systems in production of vegetables and fruit. Warm season crops are commonly produced using transplants. Evaluation of nutrient availability is needed for the use of readily available local waste-streams byproducts, such as manures and composts, for amendments or fertilizers in order to manage …

Dynamical and physical features of a long range transported dust event originating in China affecting Korea early March 2008 are examined using an integrative multi-sensor and multi-algorithm approach. Aerosol loadings and their size mode were analyzed over both ocean and land surfaces using the Moderate Resolution Imaging Spectroradiometer (MODIS) aerosol optical depth (AOD), employing standard dark target (DT) and deep blue (DB) algorithms, and the Ångström exponent (AE). Anthropogenic absorbing aerosols and smoke were found to be significant over the Indochina Peninsula, the Philippines and southern China, while a mixture of dust and pollution were predominant over central to northern …

Fundamental Mathematics Of Consciousness, Menas Kafatos

Mathematics, Physics, and Computer Science Faculty Articles and Research

We explore a mathematical formalism that ties together the observer with the observed in the view that Consciousness is primary, operating through three principles which apply at all levels, the essence of qualia of experience. The formalism is a simplified version of Hilbert space mathematics encountered in quantum mechanics. It does, however, go beyond specific interpretations of quantum mechanics and has strong philosophical foundations in Western philosophy as well as monistic systems of the East. The implications are explored and steps for the full development of this axiomatic mathematical approach to Consciousness are discussed.

Detection And Tracking Of T Cells In Time-Lapse Imaging, Cody Arbuckle, Milton L. Greenberg, Erik J. Linstead

Mathematics, Physics, and Computer Science Faculty Articles and Research

The effective classification and tracking of cells obtained from modern staining techniques has significant limitations due to the necessity of having to train and utilize a human expert in the field who must manually identify each cell in each slide. Often times these slides are filled with noise cells that are not of particular interest to the researcher. The use of computational methods has the ability to effectively and efficiently enhance image quality, as well as identify and track target cell types over large data sets. Here we present a computational approach to the in vitro tracking of T cells …

An Extension Of Herglotz's Theorem To The Quaternions, Daniel Alpay, Fabrizio Colombo, David P. Kimsey, Irene Sabadini, David P. Kimsey

Mathematics, Physics, and Computer Science Faculty Articles and Research

A classical theorem of Herglotz states that a function n↦r(n) from Z into Cs×s is positive definite if and only there exists a Cs×s-valued positive measure dμ on [0,2π] such that r(n)=∫2π0eintdμ(t)for n∈Z. We prove a quaternionic analogue of this result when the function is allowed to have a number of negative squares. A key tool in the argument is the theory of slice hyperholomorphic functions, and the representation of such functions which have a positive real part in the unit ball of the quaternions. We study in great detail the case of positive definite functions.

Boundary Interpolation For Slice Hyperholomorphic Schur Functions, Khaled Abu-Ghanem, Daniel Alpay, Fabrizio Colombo, David P. Kimsey, Irene Sabadini

Mathematics, Physics, and Computer Science Faculty Articles and Research

A boundary Nevanlinna-Pick interpolation problem is posed and solved in the quaternionic setting. Given nonnegative real numbers κ1,…,κN, quaternions p1,…,pN all of modulus 1, so that the 2-spheres determined by each point do not intersect and pu≠1 for u=1,…,N, and quaternions s1,…,sN, we wish to find a slice hyperholomorphic Schur function s so that
limr→1r∈(0,1)s(rpu)=suforu=1,…,N,
and
limr→1r∈(0,1)1−s(rpu)su¯¯¯¯¯1−r≤κu,foru=1,…,N.
Our arguments relies on the theory of slice hyperholomorphic functions and reproducing kernel Hilbert spaces.

Realizations Of Infinite Products, Ruelle Operators And Wavelet Filters, Daniel Alpay, Palle Jorgensen, Izchak Lewkowicz

Mathematics, Physics, and Computer Science Faculty Articles and Research

Using the system theory notion of state-space realization of matrix-valued rational functions, we describe the Ruelle operator associated with wavelet filters. The resulting realization of infinite products of rational functions have the following four features: 1) It is defined in an infinite-dimensional complex domain. 2) Starting with a realization of a single rational matrix-function M, we show that a resulting infinite product realization obtained from M takes the form of an (infinitedimensional) Toeplitz operator with the symbol that is a reflection of the initial realization for M. 3) Starting with a subclass of rational matrix functions, including scalar-valued ones corresponding …

Wiener-Chaos Approach To Optimal Prediction, Daniel Alpay, Alon Kipnis

Mathematics, Physics, and Computer Science Faculty Articles and Research

In this work we combine Wiener chaos expansion approach to study the dynamics of a stochastic system with the classical problem of the prediction of a Gaussian process based on part of its sample path. This is done by considering special bases for the Gaussian space G generated by the process, which allows us to obtain an orthogonal basis for the Fock space of G such that each basis element is either measurable or independent with respect to the given samples. This allows us to easily derive the chaos expansion of a random variable conditioned on part of the sample …

The Clinical Utility Of Multidisciplinary Rehabilitation In Individuals With Huntington’S Disease, Travis Miles Cruickshank

Theses: Doctorates and Masters

Background

Huntington’s disease (HD) is a chronic neurodegenerative disorder characterised by a progressive loss of cognitive function, motor control and psychiatric features. Individuals also display a variety of systemic features. Progressive neuronal dysfunction and neuronal cell death are thought to underlie the onset and progression of many clinical features of HD.

Despite scientific progress, there is still no cure or disease modifying therapy for HD, and available pharmaceutical agents only provide partial relief of motor and psychiatric features. An emerging body of evidence indicates that lifestyle enrichment may delay the onset and progression of clinical features, and exert favourable effects …

Engineering Characteristics Of Compacted Sand-Bentonite Mixtures, Ali Faisal Ghazi

Theses: Doctorates and Masters

Sand-clay mixtures are commonly used as a liner/barrier material in various engineering applications, such as construction of hydraulic and waste containments. Permeability, compressibility and strength are important properties of sand-clay mixtures and are often required for the design of the liner/barrier of the containments.

In states like Western Australia, which is covered mostly by sandy soils, engineers face difficulties with economically sourcing clays for liner/barrier applications. Any reliable research finding that recommends an optimum clay content to be used with sandy soil can be of significant importance. Such findings for the local Perth sandy soil are rarely available in the …

The N-Glycosylation Of Immunoglobulin G As A Novel Biomarker Of Parkinson’S Disease, Alyce Christine Russell

Theses: Doctorates and Masters

For neurodegenerative diseases, interventions during the early stages of the disease, before significant neurodegeneration has occurred, are associated with an increased probability of slowing or halting the disease process. In order to intervene early, it is essential that an accurate diagnosis is obtained and that disease progression can be monitored. This is particularly relevant for Parkinson’s disease (PD; International Classification of Diseases version 10) because significant neurodegeneration has already occurred by the time the clinical motor symptoms are present. Therefore, the development of translatable, high-throughput biomarkers for large scale population screening is a crucial area of research. Of promise are …

Just A “Click” Away From Evidence-Based Online Breast Cancer Information, Advice And Support Provided By A Specialist Nurse: An Ethnonetnographic Study, Cynthia Ann Witney

Theses: Doctorates and Masters

Breast cancer has had, and will continue to have, a devastating impact on the lives of many Australian women, their families, friends and the wider community. The concomitant treatment of this disease places a considerable burden on the health care system and the supporters of the person diagnosed with this disease. While there are many government and non-government organisations that provide treatment and support services for the person with breast cancer, these services are usually provided in person either in the home or at the organisation’s offices. This study extended the information advice and support aspects of these services to …

Carbon Storage And Preservation In Seagrass Meadows, Mohammad Rozaimi Jamaludin

Saying ‘No’: A Biographical Analysis Of The Experiences Of Women With A Genetic Predisposition To Developing Breast/Ovarian Cancer Who Reject Risk Reducing Surgery, Doreen Molloy

Theses: Doctorates and Masters

Background: Genetic technologies have identified some of the genes implicated in cancer susceptibility. Women with mutations in breast/ovarian cancer-susceptibility genes (BRCA1 and 2) have a lifetime combined risk of breast/ovarian cancer of more than 80%. Risk reducing surgery (RRS) reduces cancer risk by as much as 90% in high risk populations. Despite this, some BRCA1/2 mutation-positive women say no to RRS.

Purpose: To illuminate an understanding of why women at high risk of developing breast/ovarian cancer say no to risk reducing surgery (RRS).

Design: Denzin’s (1989) interpretive biography was combined with Dolby-Stahl’s (1985) literary folkloristic methodology to provide a contextualised …

Theses: Doctorates and Masters

New educational directives have an effect on the practice of teachers in schools. This study is propelled by the introduction of a national Australian Curriculum and subsequent changes to the Arts curriculum. As one of the five arts subjects, drama has been included in the primary school curriculum in Western Australia since 1997, however, its inclusion and the teaching of drama has not been consistently realised.

Teacher perspectives and beliefs about specific Learning Areas influence their planning and practice; often this is related to past experiences. This study aims to determine Year 1 teachers’ perspectives of, and practices in, drama. …

Stand-Alone Solar-Pv Hydrogen Energy Systems Incorporating Reverse Osmosis, Daniel Clarke

Theses: Doctorates and Masters

The world’s increasing energy demand means the rate at which fossil fuels are consumed has increased resulting in greater carbon dioxide emissions. For many small (marginalised) or coastal communities, access to potable water is limited alongside good availability of renewable energy sources (solar or wind). One solution is to utilise small-scale renewably powered stand-alone energy systems to help supply power for everyday utilities and to operate desalination systems serving potable water (drinking) needs reducing diesel generator dependence. In such systems, on-site water production is essential so as to service electrolysis for hydrogen generation for Proton Exchange Membrane (PEM) fuel cells. …

Antenatal Clinic: Using Ethnographic Methods To Listen To The Voices Of Pregnant Adolescents, Deborah Ireson

Theses: Doctorates and Masters

Aim: This research aims to explore the motivating reasons and external influences that affect pregnant adolescents’ reasons for attending an antenatal clinic. Background: Pregnancy during adolescence has been researched from perceived ‘poor’ decision making during pregnancy and postnatal perspectives involving high-risk outcomes for mother and baby. Antenatal clinic attendance by pregnant adolescents is often characterised by late and infrequent attendance, limiting midwifery contact with this inexperienced group. Gaps in the literature exist where the real-time voices of pregnant adolescents offer their current experiences of antenatal clinic as a relevant means to inform midwifery practice.

Research design: Using ethnographic methods, this …

Landing Performance And Lower Extremity Injuries In Competitive Surfing, Lina Elizabeth Lundgren

Theses: Doctorates and Masters

Competitive surfing involves highXrisk manoeuvres that may impose injury risk, especially in the lower extremity. Although the dynamic environment of surfing is a major factor of unpredictable determinants for injury risk, there may be athlete qualities with importance for prevention. Previous studies suggest that dynamic loading and landing tasks represent major risk factors, and should therefore be included in athlete assessments and risk analysis.

The purpose of this thesis was to investigate landing tasks that may be related to surfing performance and injury risk. It involved studying manoeuvres and landing tasks to establish its relevance for surfing athletes, develop multifactorial …

Thinking Differently About Reflective Practice In Australian Social Work Education: A Rhapsody, Lynelle Watts

Theses: Doctorates and Masters

There are many different ways of thinking about reflective practice in social work education in Australia. This research utilises a musical metaphor to illustrate this diversity. Written as a piece of music with album notes, the study utilises a reflexive methodology with a qualitative mixed method approach. Three studies were conducted to explore how reflective practice is understood in social work education and practice in Australia. The first study examined my own learning and teaching of reflective practice through an autoethnographic process. The findings indicated a range of models of reflective practice potentially available to the educator. Also explored in …
