The Fate Of Nitrogen Pollution In High-Latitude Winter: Investigations Using A 1-D Photochemical Model, Patrick L. Joyce

Chemistry and Biochemistry

Simulations using a 1-D photochemical model were performed to analyze the fate of NOx pollution in a high-latitude winter environment. Modeled pollution emissions were constrained by observations from downtown Fairbanks and the model reproduced dilution of NOx on timescales in agreement with field measurements on the edge and outside of the urban area of Fairbanks. The model was updated from previous versions to include calculations of reactions of N₂O₅ on aerosol particles and an empirically-derived value for dry deposition velocity of N₂O₅ to the snowpack, which acts as a competing loss of N₂O₅. It was found that dry deposition of …

Assessment Of Fungal And Bacterial Bioaerosols In Ambient Air In Fairbanks, Alaska, Mitali S. Patil

Chemistry and Biochemistry

Bioaerosols are solid or liquid particles of biological origin that are suspended in the surrounding air or other gaseous environments. Bioaerosols can cause diseases, allergenic or toxicological reactions, respiratory distress, and can be potential bioterrorism threats. Studies concerning ambient bioaerosols have never focused upon central Alaska, and only one experiment has utilized the DRUM (Davis Rotating Unit for Monitoring) impactor as the collection apparatus. This study focuses on the assessment and identification of fungi and bacteria present in the ambient air collected by the DRUM impactor from March 2008 to January 2009. The samples were collected on MylarTM and aluminum …

Hydrodynamics Of Downstream Pointed Guidevanes: A Case Study Of The Hess Creek Meander Bend Realignment, Alexandre W. Lai

Engineering

The hydrodynamics of downstream pointed guidevanes installed to realign an eroding meander bend upstream of the Trans- Alaska Pipeline bridge is studied. The bridge is located at Hess Creek, 137 km north of Fairbanks, Alaska. Effect of the downstream pointed vanes on bed form, erosion, longitudinal and transverse slopes, three dimensional velocity profiles, flow patterns, and other hydraulic parameters for high and low flows are compared and analyzed. Six years after installation of the vanes the realigned thalweg remains in its original design location. The longitudinal bed profile changed from a dominant continuous pool typical of natural meander bends on …

A Study Of Organizational Structures Impacting Noncredit Workforce Education And Their Effects On Determining Workforce Development Strategies In Louisiana's Community And Technical Colleges, William S. Wainwright

LSU New Orleans Theses and Dissertations

The Lumina Foundation (2007) indicates that 54 million adults in the workforce are seeking noncredit education opportunities in a credit course/program delivery system designed to meet the needs of traditional college students. Working adults seeking continuing education coupled with dislocated workers as a result of changing economic situations represents this growing population. Community and technical colleges in Louisiana benefit from a for-credit formula funding model and do not benefit from a formula funding mechanism that supports noncredit education enrollments. As Louisiana’s community and technical colleges face continuous budget challenges resulting from economic recession, college leaders are making critical decisions in …

A Darker Shade Of Blue: From Public Servant To Professional Deviant; Law Enforcement's Special Operations Culture, Louis Scott Silverii

LSU New Orleans Theses and Dissertations

Abstract

The culture of law enforcement is an all or nothing proposition with no gray area where membership into this society is concerned. You are either “on the job” or you are not. Even references among officers to “the job” indicate there is only one job. Likened to a secret handshake, that initial phrase if answered correctly opens the door to instant fraternal acceptance, get out of violation passes, and the many other assumed privileges of brotherhood. Manning (1980) describes the powerful mystification of policing as the “sacred canopy”. He further asserts that “the police role conveys a sense of …

An Experimental Study Of Formation Of Circulation Patterns In Laminar Unsteady Driven Cavity Flows Using Particle Image Velocimeter (Piv) Techniques, Jon Farkas

LSU New Orleans Theses and Dissertations

Abstract

An experimental study is conducted to determine the velocity fields, from development to steady state, in a square enclosure due to movement of a constant velocity lid using Particle Image Velocitmetry (PIV). Experiments were conducted with water, seeded with hollow glass sphere particles 10 microns in diameter, at three different lid velocities leading to Reynolds numbers in the high laminar to transitional range. Driven Cavity Flow is a classic fluid dynamics case often used for benchmarking of computational codes. Previous work has primarily focused on improving computational codes, experimental work is lacking and focused on obtaining steady state readings. …

Multivariate Models And Algorithms For Systems Biology, Lipi Rani Acharya

LSU New Orleans Theses and Dissertations

Rapid advances in high-throughput data acquisition technologies, such as microarraysand next-generation sequencing, have enabled the scientists to interrogate the expression levels of tens of thousands of genes simultaneously. However, challenges remain in developingeffective computational methods for analyzing data generated from such platforms. In thisdissertation, we address some of these challenges. We divide our work into two parts. Inthe first part, we present a suite of multivariate approaches for a reliable discovery of geneclusters, often interpreted as pathway components, from molecular profiling data with replicated measurements. We translate our goal into learning an optimal correlation structure from replicated complete and incomplete …

Development Of A Novel Electron-Transfer Secondary Reaction Matrix, Characterization Of The Site–Specificity Of Novel Bilin-Lyase, And Fundulus Grandis Protein Expression Investigation Using Mass Spectrometry, Mohamed N. Boutaghou

LSU New Orleans Theses and Dissertations

Reported in this dissertation are the results of investigations performed at the New Orleans Center for Mass Spectrometry at the University of New Orleans. The projects that are detailed in the coming pages take on a variety of subjects, but a common thread is that each employs matrix-assisted laser desorption/ionization (MALDI) mass spectrometry to solve a problem. Fundamental aspects of MALDI in-plume ionization are implicated in the introduction of a newly developed electron-transfer secondary ionization matrix. The remaining projects are related to the ever expanding field of proteomics. Mass spectrometry was used to investigate the site specificity of a newly …

Essays On An Asean Optimal Currency Area, Kathryn J. Whittaker Huff

LSU New Orleans Theses and Dissertations

Many regions of the world would like to replicate the financial and monetary integration of the European Monetary Union (EMU). Member countries of the Association of Southeast Asian Nations (ASEAN) have shown an interest in such an arrangement. ASEAN is a political, cultural, and economic association that includes Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam. Many of these nations are experiencing rapid economic development while others are still relatively poor and under developed. As such, they appear to be an unlikely group for currency unification. Older studies suggest that multiple currency union groupings may be …

Black Policemen In Jim Crow New Orleans, Vanessa Flores-Robert

LSU New Orleans Theses and Dissertations

Although historians have done in-­‐depth researched on Black police in the South, before the Civil War and during Reconstruction, they seldom assess black policemen’s role in New Orleans between the Battle of Liberty Place and 1913. The men discussed here argue that despite the hardening racial attitudes in Post-­‐ Reconstruction South, in New Orleans opportunity still existed for Blacks to serve in positions of authority, perhaps a heritage of the city’s earlier tri-­‐partite racial order. The information obtained from primary sources such as police manuals, beat books, and newspapers, counters the widely held belief that African American presence in the …

Exchange Flows In An Urban Water Body: Bayou St. John Responses To The Removal Of Flood Control Structures, Future Water Elevation Control, And Water Quality, Robin L. Schroeder

LSU New Orleans Theses and Dissertations

Bayou St. John, an urban water body extending south from Lake Pontchartrain, has two anthropogenic structures that regulate flow from the Lake . The City of New Orleans has plans to remove the inner control structure to improve water quality. Field and numerical methods used in this study show removing this structure increased water elevations throughout the Bayou but resulted in lower water elevation signal amplitudes that caused a lower tidal flow exchange from north to south. Bulk Richardson numbers showed mixing was inversely related to flow and the Bayou generally remains stratified. Resuspension of contaminated sediment could negatively impact …

The Women And Peace Hypothesis In The Age Of Nancy Pelosi: Can Female Leaders Bring About World Peace?, Jeannette Haynie

LSU New Orleans Theses and Dissertations

The women and peace hypothesis suggests that women are more likely than men to choose peace and compromise over violent conflict, whether as ordinary citizens or as government leaders. I test this concept by analyzing the percent of women in the parliaments and executive cabinets of 93 nations over a 31-year-period, comparing these figures to the presence of violent interstate conflicts for each country-year. Controlling for wealth, democratic status, national capabilities, military expenditures, and contiguity, I find moderate support for the women and peace hypothesis. This support continues when democratic system type is interacted with the measured office. While women …

The Effects Of Negative Publicity On The Performance Of Professional Baseball Athletes., Crystal M. Smallwood

Undergraduate Honors Theses

This study researched the effects of negative publicity on the performance of professional baseball athletes. Four athletes’ performance statistics were evaluated before a scandal that produced negative publicity, during the height of the negative publicity and after the scrutiny tapered off. Chipper Jones, Wade Boggs, Alex Rodriguez and David Justice were the athletes chosen for the study, and all four athletes experienced a similar scandal and negative publicity about their personal and professional lives. The results showed an effect on performance, but it was not always negative and could not be definitively linked to the negative exposure in the media. …

Saturday Extra: Guerilla Civic Engagement On The Landscape, John M. Rudy

Interpreting the Civil War: Connecting the Civil War to the American Public

Over at Civil War Memory, Kevin Levin brought the community's attention to some installations placed on the fences surrounding a few of the statues along Monument Avenue in Richmond, Virginia. The signs are a redress of sorts to the Confederate narrative told through granite, marble and bronze on the massive monuments. They highlight black citizens of Virginia who challenged the racist establishment of the state throughout its history. [excerpt]

Play Therapists’ Practice Patterns And Perceptions Of The Factors That Influence Caregiver Engagement In Play Therapy, Adrianne R. Lolan

LSU New Orleans Theses and Dissertations

Much effort has been expended to increase the awareness and understanding of play therapy among consumers and practitioners (Landreth, 1991) since its introduction by Virginia Axline during the 1940s. As with any form of counseling, Leblanc and Ritchie (1999) have noted there are factors considered key to successful play therapy treatment outcomes. Play therapy research shows a positive relationship between parent's involvement in play therapy and successful outcomes (LeBlanc & Ritchie, 1999; Bratton, Ray, Rhine, & Jones, 2005) but little research exists to document specific practice patterns and perceptions of play therapists in relation to achieving caregiver engagement. The purpose …

Ecosystem Management And Its Application At The Local Level: Apnep, Cama And Local Land Use Planning In North Carolina, Traci L. Birch

LSU New Orleans Theses and Dissertations

A fundamental purpose of state-mandated growth management has been to infuse regional environmental concerns into local land use planning. Similarly, collaborative ecosystem planning efforts have attempted to encourage local communities to participate in regional planning efforts, and to adopt regional environmental goals and objectives into local land use plans. This paper presents results from a study of state-mandated local planning and collaborative regional planning, addressing in particular local ability to adopt and implement ecosystem planning initiatives for development management.

I found that a state mandate not only achieves plans from communities that would not otherwise plan, but also the plans …

The Operation Was Successful But The Patient Died: The Politics Of Crisis And Homelessness In Post-Katrina New Orleans, Evan Casper-Futterman

LSU New Orleans Theses and Dissertations

On July 4^th, 2007, a small group of housing activists set up a tent city encampment in a plaza adjacent to New Orleans City Hall. The action resulted in the creation of Homeless Pride, a small group of politicized Plaza residents. Six months later, hundreds of homeless people were moved from the park, and it was fenced off. Using archival videos, interviews, and news media, this thesis analyzes the opportunities and constraints that activists, service providers, and local officials faced in light of two intersecting and overlapping contexts. The first context is the immediate crisis of the levee …

Analysis Of Biomass/Coal Co-Gasification For Integrated Gasification Combined Cycle (Igcc) Systems With Carbon Capture, Henry A. Long Iii

LSU New Orleans Theses and Dissertations

In recent years, Integrated Gasification Combined Cycle Technology (IGCC) has become more common in clean coal power operations with carbon capture and sequestration (CCS). Great efforts have been spent on investigating ways to improve the efficiency, reduce costs, and further reduce greenhouse gas emissions. This study focuses on investigating two approaches to achieve these goals. First, replace the subcritical Rankine steam cycle with a supercritical steam cycle. Second, add different amounts of biomass as feedstock to reduce emissions. Finally, implement several types of CCS, including sweet- and sour-shift pre-combustion and post-combustion.

Using the software, Thermoflow®, this study shows that utilizing …

Therapist's Perceptions Of Walk And Talk Therapy: A Grounded Study, Bridget L. Mckinney

LSU New Orleans Theses and Dissertations

Our society has become less physically active (U.S. Department of Health and Human Services, 2010) and less connected to nature than ever before (Berger & Mcleod, 2006). Spending leisure time indoors, technological advancements, urban living, and car dependent communities have led to these changes (Dustin, Bricker, & Schwab, 2010; Hansen-Ketchum, Marck, & Reutter, 2009; Norman & Mills, 2004). As a result, physical health and mental health is deteriorating (Dustin et al., 2010; Maller, Townsend, Pryor, Brown & Leger, 2005). Physical activity and nature can each produce mental and physical health benefits; some approaches such as adventure-based counseling and wilderness therapy …

Milneburg, New Orleans: An Anthropological History Of A Troubled Neighborhood, Betty A. Smallwood

LSU New Orleans Theses and Dissertations

For nearly 200 years, there has been a neighborhood in New Orleans, Louisiana named Milneburg, which has been constantly reimagined by its inhabitants and others. From its inception as a port of entry in 1832 until the 2011, it has been called a world-class resort, the poor-man's Riviera, a seedy red-light district, a cradle of jazz, a village, a swath of suburbia and a neighborhood. It has been destroyed eight times due to storms, fires, and civic or governmental neglect. Each time its residents have rebuilt it. In its last iteration as a post-Katrina neighborhood, the residents reestablished the Milneburg …

Exploring Parent-Adolescent Conflict: An Examination Of Correlates And Longitudinal Predictors In Early Adolescence, Jessica A. Melching, Jessica A. Melching

LSU New Orleans Theses and Dissertations

Previous research has focused on developmental trends in parent-adolescent conflict without extensively describing individual differences in conflict. The current study tested child factors, parent factors, contextual factors, and adolescence-specific factors as concurrent correlates and longitudinal predictors of parent-adolescent conflict. Participants include 218 mother-child dyads, adolescents’ mean age (11years, 11months). Parent and adolescent data was collected during the summers following the adolescents’ 5^th and 6^th grade years. All four groups of variables were associated with parent-adolescent conflict. The child group of factors emerged as the most consistent group of variables concurrently and longitudinally.
