Species Boundaries, Biogeography, And Intra-Archipelago Genetic Variation Within The Emoia Samoensis Species Group In The Vanuatu Archipelago And Oceania, Alison Madeline Hamilton

LSU Doctoral Dissertations

Speciation, geographic variation, and genetic differentiation are fundamental processes that generate diversity, and understanding these processes are major goals of evolutionary biology. Evolutionary phenomena may be more observable on islands as compared to continental landmasses as a result of small population sizes, unoccupied niches, and the relative simplicity of island systems and their populations: physical isolation, shorter (and often well documented) geologic time scale, reduced faunal diversity, and lack of outside faunal influence. Yet, despite their incredible diversity, Pacific island faunas have received little research attention relative to other tropical regions. Using molecular data from several species of scincid lizards …

The Impact Of Natural Disasters On Employee Turnover: The Shocks And After-Shocks Of Hurricane Katrina On It Professionals, James Davis

LSU Doctoral Dissertations

Hurricane Katrina was the most destructive natural disaster in American history and created the need for organizations along the Gulf Coast to employ disaster management and recovery plans. With the ubiquitous nature of computers and technology, IT professionals were critical organizational assets in executing those plans in order to insure the safety and recovery of valuable information. The purpose of this study is to gain a deeper understanding of the impact natural disasters have on IT professionals and their subsequent turnover decisions. The theoretical guide for this study was the Unfolding Model of Turnover (Lee and Mitchell 1994) that identifies …

Microchannels provide very high heat transfer coefficients because of their small hydraulic diameters. In this study, an investigation of fluid flow and heat transfer in microchannels is conducted. A review of the literature published regarding fluid flow and heat transfer in microchannels is provided in this study. A thorough background on the theory of internal convective heat transfer is provided as well. A critical analysis of some of the published heat transfer experiments on microchannels is also given. It was found that …

Comparisons Of Bacterial Community Within The Abdomens Of Formosan Subterranean Termites, Fresh- And Alcohol-Stored, From Their Native (China) And Introduced (U.S.) Range, Huei-Yang Ho

LSU Master's Theses

The Formosan subterranean termite (FST), a pest species native to China and introduced to the U.S., is obligatorily dependent on its gut microbiota. Using high-throughput 16S rRNA gene sequencing, the effects of long-term alcohol storage and geographic location on the bacteria composition of the FST colonies were investigated. Initial studies found the use of amplified ribosomal DNA restriction analysis (ARDRA) to be unpractical due to its higher costs compared to the direct sequencing of 16S rRNA gene sequences. Using nine FST colonies consisting of fresh and alcohol-stored Lousiana FST colonies and alcohol-stored China FST colonies, 237 bacteria ribotypes were identified …

It's Not Rocket Science: Nasa's Crisis Communication Efforts As A Public Sector Organization Following The Columbia Shuttle Disaster, Emily Ann Schult

LSU Master's Theses

Seventeen years after the Challenger accident, the space shuttle Columbia and its crew were only forty miles from Kennedy Space Center when the shuttle exploded during re-entry to the Earth’s atmosphere. The explosion killed all seven astronauts onboard. NASA, the National Aeronautics and Space Administrations immediately jumped into action, declaring a contingency and following the Agency Contingency Action Plan for Space Flight Operations. As a public sector organization, one that must report to Congress and the American public, NASA is held to different standards than private organizations when it comes to releasing information. To understand how public sector organizations handle …

The Impact Of Self-Reported Physical Activity Levels On The Prediction Of Body Fatness From Bmi In White And Black College Students, Michael Zanovec

LSU Master's Theses

The purpose of this study was to test the hypothesis that self-reported physical activity (PA) levels quantified from the International Physical Activity Questionnaire (IPAQ) could be used to improve the prediction of percent body fat (%BF) measured by dual-energy X-ray absorptiometry (DXA) from body mass index (BMI), gender, and race in White and Black college students. A total of 278 students, aged 18 – 24 yr, volunteered to participate. There were 133 males (85 White and 48 Black) and 145 females (77 White and 68 Black). Total activity levels were quantified in MET-hours per week (MET-hrs•wk-1) using the IPAQ short …

Hierarchical Linear Modeling Against The "Gold Standard" Of Visual Analysis In Single-Subject Design, Elizabeth S, Godbold

LSU Master's Theses

Visual analysis is the “Gold Standard” for single-subject data because of two assumptions: a low Type I error rate and consistency across raters. However, research has shown it less reliable and accurate than desired. Autocorrelation, variability, trend, lack of obvious mean shift, and differences in the physical presentation of graphs contribute to inconsistencies and higher error rates. Statistical analysis has been advocated as a judgmental aid to visual analysis, but an appropriate statistic has not been found. In the present study, the accuracy of Hierarchical Linear Modeling was compared to raters’ visual analysis of previously published data using Receiver Operating …

Enhancing Security In Quantum Cryptography, Partha Basuchowdhuri

LSU Master's Theses

Quantum Key Distribution was named as one of the top ten emerging technologies by Technology Review Journal in 2003 in their annual edition. The growth in quantum cryptography since the beginning of the millennium has been expedited by new theories and ideas. The introduction of practical quantum cryptosystems offered by USA based company MagiQTech and its European rival idQuantique has changed the face of cryptography. With active experimental research in USA, Europe, Japan and Singapore, the scope of quantum cryptography seems to be growing daily. When Bennett and Brassard proposed their BB84 protocol in Bangalore in 1984, no one would …

An Evaluation Of The Perceived Obstacles For Policy Officials Regulating The Post Harvest Treatment Of Raw Oysters To Control The Human Health Vibrio Vulnificus Problem, Amy Leah Oestringer

LSU Master's Theses

Vibrio vulnificus is the leading pathogen linked to seafood-associated deaths. This naturally occurring marine bacterium presents a human health risk when it is consumed in raw oysters. Hospitalization is necessary in 90 % Vibrio vulnificus illnesses and 40% end in death. (CDC) Several guidelines and regulations have been enacted to combat this human health issue, but have failed to reduce the steadily rising illness rate. Post-harvest processing requirements for raw oysters could be used to reduce illness rates. A survey was conducted to measure the perceived obstacles that regulators and industry representatives of the raw oyster industry face in policymaking …

The Color Appearance Of Stimuli Detected Via Short-Wavelength-Sensitive Cones: Comparisons With Visual Adaptation And Visual Field Data For Peri- Or Post-Menopausal Women Under 70 Years Of Age, Alvin Eisner, Maureen D. Toomey

Community Health Faculty Publications and Presentations

Dynamics of foveal light adaptation for vision mediated via short-wavelength-sensitive (SWS) cones were compared for two groups of healthy amenorrheic (peri- or post-menopausal) women not using hormonal medication. Each subject was assigned to a group based on the color name – “lavender” (~2/3 of all subjects) or "white" (~1/3 of all subjects) – chosen in a forced-response paradigm to best describe a threshold-level 440-nm test presented on a larger 3.6 log td 580-nm background that had been viewed for ~5 minutes. During the first 20–30 seconds after this 3.6 log td background abruptly replaced a much dimmer background, the threshold …

Impact Of Agricultural Productivity Changes On Agricultural Exports, Ananda Bahadur Gurung

Agribusiness and Applied Economics

This study uses linear programming and econometric tools to determine the impact of agricultural productivity (technology) on agricultural exports. The study determines total factor productivity (TFP) using the Malmquist index method for a panel of 64 countries. Productivity impact on exports is determined by a two-stage estimation procedure. The results show agricultural productivity affects agricultural exports. This has important implications for developing countries. A 1 unit change in cumulative TFP increases agricultural output by .79% and a 1% increase in estimated agricultural output increases exports by .37%. Therefore, the total effect of technology on exports of primary and processed commodities …

Productivity Growth In The U.S. Trucking Industry, Steven Condon

Agribusiness and Applied Economics

The performance of the trucking industry is very important to the economy given that it moves nearly 70 percent of the nation's freight (Tall et al. 2005). The more efficient and productive trucking fins are, the less the shipping costs are for the trucking firm managers and the end consumers or businesses. Consequently, it has become vital to keep the trucking industry running efficiently and continuing to improve productivity. Productivity change of 115 of the largest firms in the United States was determined for the years 1999 and 2003. The Malmquist Productivity Index was decomposed into technical efficiency change and …

Factors Influencing Potato Production In North Dakota, Zoe Taryn Margaux Roberson Zetina

Agribusiness and Applied Economics

Spatial shifts and structural changes continue to occur in the United States agricultural industry. Researchers have documented that the potato industry has changed in response to demands of consumers, expectations of producers and improvements in research and development. The aim of this study was to provide empirical evidence that both institutional and infrastructural factors are important to potato production in North Dakota. Using secondary county-level potato production data for North Dakota, an empirical model was designed to estimate the direction and impact of growers' expectations of prices, yields and costs on their decision to produce potatoes. The results confirmed that …

Impact Of Climate Change And Weather Variability On North Dakota Agriculture, Chol Permina Mayom

Agribusiness and Applied Economics

This study used county-level yields and panel data (1950-2006) to explain the Impact of climate change and weather variability on North Dakota agriculture by estimating the effect of variation in temperature and precipitation on the yields of four major crops: com, durum, soybeans and wheat. In addition to yields, the study examined Impacts of climate change on crop gross revenues per acre for all 53 counties in North Dakota. An econometric model was developed to infer statistical relationships between weather variability and crop yields. Fixed and random effects models were employed to estimate the impacts of climate variables (temperature and …

Locke On Consciousness, Angela M. Coventry, Uriah Kriegel

Philosophy Faculty Publications and Presentations

Locke’s theory of consciousness is often appropriated as a forerunner of present-day Higher-Order Perception (HOP) theories, but not much is said about it beyond that. We offer an interpretation of Locke’s account of consciousness that portrays it as crucially different from current-day HOP theory, both in detail and in spirit. In this paper, it is argued that there are good historical and philosophical reasons to attribute to Locke the view not that conscious states are accompanied by higher-order perceptions, but rather that conscious states constitute perceptions of themselves.

How Does Culture Count In Legal Change?: A Review With A Proposal From A Social Movement Perspective, Setsuo Miyazawa

Faculty Scholarship

We have in this volume four articles on legal change in China and Japan written by four distinguished authors. These articles vary with regard to subject state, specificity of issues, and breadth of analytical scope. They commonly discuss one factor, however: culture. The purpose of this Comment is to examine the way each article uses culture in its explanations of legal change. The Comment concludes with a brief suggestion, from a social movement perspective, on employing culture as an explanatory tool in a non-essentialist way.

Education And The Age Profile Of Literacy Into Adulthood, Elizabeth Cascio, Damon Clark, Nora Gordon

Dartmouth Scholarship

American teenagers perform considerably worse on international assessments of achievement than do teenagers in other high-income countries. This observation has been a source of great concern since the first international tests were administered in the 1960s. But does this skill gap persist into adulthood? We examine this question using the first international assessment of adult literacy, conducted in the 1990s. We find that, consistent with other assessments of the school-age population, U.S. teenagers perform relatively poorly, ranking behind teenagers in the twelve other rich countries surveyed. However, by their late twenties, Americans compare much more favorably to their counterparts abroad: …

The Warps Survey. Vii. The Warps‐Ii Cluster Catalog, Donald J. Horner, Eric S. Perlman, Harald Ebeling, Laurence Jones, Caleb A. Scharf, Gary Wegner, Matthew Malkan, Ben Maughan

Dartmouth Scholarship

We present the galaxy cluster catalog from the second, larger phase of the Wide Angle ROSAT Pointed Survey (WARPS), an X-ray selected survey for high-redshift galaxy clusters. WARPS is among the largest deep X-ray cluster surveys and is being used to study the properties and evolution of galaxy clusters. The WARPS-II sample contains 125 clusters serendipitously detected in a survey of 301 ROSAT PSPC pointed observations and covers a sky area of 56.7 deg². Of these 125 clusters, 53 have not been previously reported in the literature. We have nearly complete spectroscopic follow-up of the clusters, which range …

Scaling Up And Moving In: Connecting Social Practices Views To Policies And Programs In Adult Education, Stephen Reder

Applied Linguistics Faculty Publications and Presentations

The social practices framework has had a major impact on adult literacy and numeracy research over the past quarter century in the US, the UK and other countries. To date, the social practices view has had far less influence on the development of policies and programs in adult literacy and numeracy education. To help this happen, new kinds of assessment tools aligned with the social practices framework are needed to support appropriate changes in curriculum design, learner assessment and program evaluation.
In this article research is presented that illustrates how measures of adults’ engagement in literacy and numeracy practices can …

Increased Hiv Risk Associated With Criminal Justice Involvement Among Men On Methadone, Matthew Epperson, Nabila El-Bassel, Louisa Gilbert, E. Roberto Orellana, Mingway Chang

School of Social Work Faculty Publications and Presentations

This paper examines the relationship between HIV risk and criminal justice involvement among a random sample of 356 men enrolled in methadone maintenance treatment programs in New York City. Bivariate and logistic regression analyses were performed to estimate the associations between measures of criminal justice involvement and participant HIV risk, controlling for socio-demographic variables. A lifetime history of incarceration was significantly associated with being HIV positive (Adjusted OR = 5.08). Recent arrest was associated with unprotected vaginal sex and having multiple female sexual partners. Sex trading was associated with both arrest and incarceration, and the strongest association was found between …

Bin Half Full: Construction Waste Recycling Solutions, Mary L. Grothaus, Melissa Johnston, Shaun Roland, Christina Skellenger, Amy Twilegar

Master of Urban and Regional Planning Workshop Projects

According to the City of Portland’s Office of Sustainable Development (OSD), construction, remodeling, and demolition (CR&D) waste comprises 20 percent of the City’s waste stream. Additionally, per capita waste generation in this sector is increasing faster than in the residential or commercial sectors. However, the current amount of CR&D waste that is landfilled can be reduced: 90 percent of the waste from a typical project can be diverted from landfill disposal. Although OSD currently requires that 50 percent of CR&D waste from every project is recycled, the City estimates that contractors recycle slightly less than this. OSD’s Portland Recycles! Plan …

Providing Information Literacy Instruction To Graduate Students Through Literature Review Workshops, Hannah Gascho Rempel, Jeanne R. Davidson

Library Faculty and Staff Publications and Presentations

As future professionals, graduate students must be information literate; however, information literacy instruction of graduate students is often neglected. To address this need, we created literature review workshops to serve graduate students from a wide range of subject disciplines at a point of shared need. Not only did this strategy prove to be successful in reaching a large number of students from a wide range of subject disciplines, the data gathered from the students identified some of the gaps graduate students have in their knowledge about library services.
