The study utilizes survey methodology to measure changes in organizational output, customer satisfaction, and employee behavior. In addition, number of employees supervised, strategies employed to adapt to the effects of activation on operations, organizational types, and the amount of time required for the organization to return to pre-activation levels of performance were measured. The sample was …


An Uncertainty-Based Approach To The Total Maximum Daily Load Development, Abhijit Patil Jan 2009

An Uncertainty-Based Approach To The Total Maximum Daily Load Development, Abhijit Patil

LSU Doctoral Dissertations

A Bayesian-updating approach is developed to the estimation of the total uncertainty-based Margin of Safety (MOS) for Total Maximum Daily Load calculations using the watershed modeling tool HSPF. In order to determine the prior, likelihood, and posterior distributions of uncertainties involved in Bayesian approach, various probability density functions are derived. The temperature measurement induced uncertainty in dissolved oxygen simulation is found to be normally distributed. The temporal scale uncertainty in weather data decreases with decreasing temporal resolution. The temporal-scale uncertainties in the rainfall and temperature data follow a Weibull and general extreme value distributions, respectively. The spatial-resolution uncertainty in simulated …


Carbon Capture And Sequestration: Identifying And Managing Risks, Alexandra B. Klass, Elizabeth J. Wilson Jan 2009

Carbon Capture And Sequestration: Identifying And Managing Risks, Alexandra B. Klass, Elizabeth J. Wilson

Articles

Carbon capture and geologic sequestration (CCS) technology promises to provide deep emissions cuts, particularly from coal power generation, but deploying CCS creates risks of its own. This article first considers the risks associated with CCS, which involves capturing CO{sub 2} emissions from industrial sources and power plants, transporting the CO{sub 2} by pipeline, and injecting it underground for permanent sequestration. The article then suggests ways in which these risks can be minimized and managed and considers more broadly when or if CCS should be deployed or whether its use should be limited or rejected in favor of other solutions.

A Metaheuristic For The Pickup And Delivery Problem With Split-Loads And Its Extension, Dai Yao Jan 2009

A Metaheuristic For The Pickup And Delivery Problem With Split-Loads And Its Extension, Dai Yao

Dissertations and Theses Collection (Open Access)

In this dissertation, we study improvements in the Pickup and Delivery Problem that can be achieved by allowing multiple vehicle trips to serve a common load. We explore how costs can be reduced through the elimination of the constraint that a load must be served by only one vehicle trip. Specifically, we investigate the problem of routing vehicles to serve loads that have distinct origins and destinations, with no constraint on the amount of a load that a vehicle may serve at a time. We develop a metaheuristic to solve large scale practical size problems in this form and apply …


Does Morningstar Shine In The Universe Of Mutual Funds? A Study On Morningstar Mutual Fund Ratings, Wee Seng Ng Jan 2009

Does Morningstar Shine In The Universe Of Mutual Funds? A Study On Morningstar Mutual Fund Ratings, Wee Seng Ng

Dissertations and Theses Collection (Open Access)

Using data from Morningstar Principia CDs and employing standard methodologies, we examine the extent to which two mutual fund ratings: Morningstar star ratings and Morningstar stewardship grades can predict future fund performance. In particular, we investigate whether the combined predictive power of the two ratings exceeds that of a single rating. We decompose funds into various groups characterized by fund age and fund categories in order to address such issues as whether predictive performance is uniform across characteristic-based groups. Although our analysis shows that none of the ratings alone possesses strong predictive power, there is statistical evidence to support the …


The Effects Of Patent Characteristics As Signals On The Growth Of Follow-On Innovations: Evidence From Chinese Patenting Activities In U.S, Wenxin Guo Jan 2009

The Effects Of Patent Characteristics As Signals On The Growth Of Follow-On Innovations: Evidence From Chinese Patenting Activities In U.S, Wenxin Guo

Dissertations and Theses Collection (Open Access)

As global trade and business activities intensified, cross-national patenting activities have been playing an increasingly important role in the process of innovation accumulation and growth. However, few studies (to my knowledge) have examined the characteristics of cross-national patents and their relationship to the accumulation and growth of innovation, especially in the context of a developing versus a developed country.
Motivated by the anecdotal evidence and `Patent Signaling Theory'(Spence, 1973), I investigate the possible influential factors on the `quality' of a US patent with a Chinese priority (thereafter `US-CN' patent) and their impact on the growth of follow-on innovation. By developing …

Youth Volunteerism: By Looking At Who Volunteers And Why Organizations May Be Able To Recruit Youth To Become Long-Standing Volunteers, Kathryn M. Zimmerly Jan 2009

Youth Volunteerism: By Looking At Who Volunteers And Why Organizations May Be Able To Recruit Youth To Become Long-Standing Volunteers, Kathryn M. Zimmerly

Graduate Research Papers

In 1835 Alexis de Tocqueville suggested volunteerism could reduce antisocial or criminal behavior (Uggen and Janikula, 1999). When looking at volunteerism today researchers have concluded similar aspects; for example, Uggen and Janikula found in their 1999 research that volunteers had increased self -acceptance, instrumentality, and civic identity.

Research by the Independent Sector suggests that 70 percent of youth volunteers feel volunteering is important because it gives them a new perspective, allows them to participate for a good cause, and gives them a greater respect for the people they are helping. Youth volunteer levels have increased (to 70 percent from 59 …


Living Originalism, Peter J. Smith, Thomas Colby Jan 2009

Living Originalism, Peter J. Smith, Thomas Colby

GW Law Faculty Publications & Other Works

Originalists routinely argue that originalism is the only coherent and legitimate theory of constitutional interpretation. This Article endeavors to undermine those claims by demonstrating that, despite the suggestion of originalist rhetoric, originalism is not a single, coherent, unified theory of constitutional interpretation, but is rather a disparate collection of distinct constitutional theories that share little more than a misleading reliance on a common label. Originalists generally agree only on certain very broad precepts that serve as the fundamental underlying principles of constitutional interpretation: specifically, that the “writtenness” of the Constitution necessitates a fixed constitutional meaning, and that courts that see …

The Freshwater Mussels (Mollusca: Bivalvia: Unionidae) Of The Channelized Missouri River, Ellet Hoke Jan 2009

The Freshwater Mussels (Mollusca: Bivalvia: Unionidae) Of The Channelized Missouri River, Ellet Hoke

Journal of the Iowa Academy of Science: JIAS

The lower Missouri River has historically been viewed as a fauna! barrier for unionids due to high sediment load. However this survey of the lower (channelized) Missouri River documented the presence of 14 unionid species and the exotic Corbicula fluminea (Muller, 1774). Unionids are present in stable substrates sheltered from the effects of the river's strong currents. Analysis of early literature on the Missouri River suggests reports of an absence of unionids were not based upon thorough fieldwork, and the most commonly cited rationale for their reported absence, the high sediment load in the river, is not convincing. Pre-1938 unionid …


Casino Royale And Franchise Remix: James Bond As Superhero, Robert P. Arnett Jan 2009

Casino Royale And Franchise Remix: James Bond As Superhero, Robert P. Arnett

Communication & Theatre Arts Faculty Publications

The article discusses the role of the film "Casino Royale" in remixing the James Bond franchise. The author believes that the remixed Bond franchise has shifted its genre to a superhero franchise. When Sony acquired MGM in 2004, part of its plan was to transform the 007 franchise at par with "Spiderman." The remixed franchise re-aligns its franchise criteria with those established by superhero films. The author cites "Casino Royale's" narrative structure as an example of the success of the film as franchise remixed for the future. The portrayal of Bond as a superhero by actor Daniel Craig is discussed.

Children's Exposure To Lead And Nickel In Esperance - A Case Study, Matthew Tristan Winters Jan 2009

Children's Exposure To Lead And Nickel In Esperance - A Case Study, Matthew Tristan Winters

Theses : Honours

This is a cross-sectional study of lead and nickel exposure of children aged 2-12 years living at varying distances from a point source of pollution in Esperance. Esperance was an ideal case study location because of previous environmental contamination with lead and nickel above background levels. Non-invasive biological samples of hair, toenails and urine were collected from participating children, and environmental samples, including house dust, soil and drinking water were also sampled from each participant household. Exposure was assessed by measuring the concentration of metals found in the biological samples, and determining their relationships with the environmental samples from each …


An Investigation Into Student Reactions Towards Rad Versus Traditional Programming Environments For Novice Developers, Pansy Colkers Jan 2009

An Investigation Into Student Reactions Towards Rad Versus Traditional Programming Environments For Novice Developers, Pansy Colkers

Theses : Honours

The traditional approach to programming using text editors is widely used in many institutions to teach introductory programming. These types of traditional programming environments provide fundamental programming concepts for learning, especially in the context of novice developers. In recent years, teaching institutions have seen a trend towards the introduction of visual "drag-and-drop" rapid application development (RAD) environments for teaching novice programmers. These 'environments capture student interest in programming by allowing the construction of workable programs within a short time frame based on minimal pre-existing coding knowledge. However, some have argued that these visual RAD environments might not be suitable for …


Making The Invisible, Visible : Exploring Liminality Of Mind And Body Through Glass, Naomi Hunter Jan 2009

Making The Invisible, Visible : Exploring Liminality Of Mind And Body Through Glass, Naomi Hunter

Theses : Honours

It is through the discipline of visual arts that I research the subject of the mind-body relationship and the notion of liminality- this is the space in-between. To that end, the aim of this research is to investigate and construct a visible means of exhibiting liminal space. This creative work will be used as a metaphor for the synergy between body and mind, which I contend occurs within an internal liminal space. I investigate these concepts through the double articulation of creative practice and a written exegesis, based on the following research questions: 'In what ways can glass be used …


Using Decision Analytic Modelling To Simulate Pregnancy, Jeffrey Cannon Jan 2009

Using Decision Analytic Modelling To Simulate Pregnancy, Jeffrey Cannon

Theses : Honours

Decision analytic modelling enables decision makers to assess the cost-effectiveness associated with a proposed change in a cunent system without physically implementing the changes. This can be achieved by formulating a mathematical model that represents all the major events occuning in the system through fmmulas and algorithms, and estimating the likely outcomes along with their costs. This type of modelling has been identified by the State Health Research Advisory Council (SHRAC) of the Western Australian Depmiment of Health as an asset for the plmming of health care investments in the future. One such area in which the Western Australian Department …


Quc-Tree: Integrating Query Context Information For Efficient Music Retrieval, Jialie Shen, Dacheng Tao, Xuelong Li Jan 2009

Quc-Tree: Integrating Query Context Information For Efficient Music Retrieval, Jialie Shen, Dacheng Tao, Xuelong Li

Research Collection School Of Computing and Information Systems

In this paper, we introduce a novel indexing scheme-query context tree (QUC-tree) to facilitate efficient query sensitive music search under different query contexts. Distinguished from the previous approaches, QUC-tree is a balanced multiway tree structure, where each level represents the data space at different dimensionality. Before the tree structure construction, principle component analysis (PCA) is applied for data analysis and transforming the raw composite features into a new feature space sorted by the importance of acoustic features. The PCA transformed data and reduced dimensions in the upper levels can alleviate suffering from dimensionality curse. To accurately mimic human perception, an …

For virtually all Filipinos, a college diploma symbolizes the attainment of a major life's goal, along with the hard work that led to its attainment, and the promise of professional success, financial stability, and personal stature.  Completion of a college education being a developmental milestone in actuality or from the perception of students and their families, it behooves human developmental specialists studying the transition from adolescence to adulthood to examine the Filipino college experience.  In particular, it is important to characterize, in the context of school experience, how Filipino youth develop the competencies and outlook for effectively recognizing and assuming …


A Framework For Temperature Imaging Using The Change In Backscattered Ultrasonic Signals, Yuzheng Guo Jan 2009

A Framework For Temperature Imaging Using The Change In Backscattered Ultrasonic Signals, Yuzheng Guo

All Theses and Dissertations (ETDs)

Hyperthermia is a cancer treatment that elevates tissue temperature to 40 to 43oC. It would benefit from a non-invasive, safe, inexpensive and convenient thermometry to monitor heating patterns. Ultrasound is a modality that meets these requirements. In our initial work, using both prediction and experimental data, we showed that the change in the backscattered energy: CBE) is a potential parameter for TI. CBE, however, was computed in a straightforward yet ad hoc manner. In this work, we developed and exploited a mathematical representation for our approach to TI to optimize temperature accuracy. Non-thermal effects of noise and motion confound the …


Factors Affecting Size And Swelling Of Poly(Ethylene Glycol) Hydrogel Microspheres Formed In Aqueous Sodium Sulfate Solutions, Michael Nichols Jan 2009

Factors Affecting Size And Swelling Of Poly(Ethylene Glycol) Hydrogel Microspheres Formed In Aqueous Sodium Sulfate Solutions, Michael Nichols

All Theses and Dissertations (ETDs)

The lower critical solution temperature: LCST) behavior of poly(ethylene glycol): PEG) in aqueous sodium sulfate solutions was exploited to fabricate hydrogel microspheres under mild conditions without the use of other monomers, polymers, surfactants or organic solvents. Reactive PEG derivatives underwent thermally induced phase separation to produce spherical PEG-rich domains that coarsened pending gelation, resulting in stable hydrogel microspheres that were polydisperse in size. The degree of reaction prior to phase separation, reaction rate within the PEG-rich domains, and duration of the reaction were independently varied to elucidate their effects on final microsphere size and gain insight regarding the mechanism of …

Modeling And Identification Of Differentially Regulated Genes Using Transcriptomics And Proteomics Data, Thanura Elvitigala

All Theses and Dissertations (ETDs)

Photosynthetic organisms are complex dynamical systems, showing a remarkable ability to adapt to different environmental conditions for their survival. Mechanisms underlying the coordination between different cellular processes in these organisms are still poorly understood. In this dissertation we utilize various computational and modeling techniques to analyze transcriptomics and proteomics data sets from several photosynthetic organisms. We try to use changes in expression levels of genes to study responses of these organisms to various environmental conditions such as availability of nutrients, concentrations of chemicals in growth media, and temperature. Three specific problems studied here are transcriptomics modifications in photosynthetic organisms under …
