7,8-Dihydroxyflavone, A Selective Tyrosine Kinase Receptor B Agonist And Bdnf Mimic, Promotes Angiogenesis., Jeremy Williams

Undergraduate Honors Theses

7,8-dihydroxyflavone (7,8-DHF), which is a member of the flavonoid family, is a selective tyrosine kinase receptor B (TrkB) agonist that has neurotrophic effects in various neurological diseases such as ischemic stroke and Parkinson’s disease [3]. In this study, we assessed the angiogeneic effect of 7,8-DHF in endothelial cells derived from resistance vessel of the brain. Angiogenesis by 7,8-DHF is an important factor that helps prevent and treat various ischemic diseases. In this study, we found that rat RV cells used in the experiment possess the TrkB receptor. Our data also demonstrates that 7,8-DHF is able to stimulate cell proliferation in …

Brain-Derived Neurotrophic Factor Levels In D2 Receptor Primed Adolescent Rats Given Twice Daily Nicotine Administrations., Josie Minnigh

Undergraduate Honors Theses

Nicotine use is very prevalent in the schizophrenic population, which is a 2.5 fold greater than the general population. In the present study, the drug quinpirole (dopamine D2/D3 agonist) or saline was given neonatally to 25 Sprague-Dawley male and female rats. Rats were randomly assigned to condition. Beginning postnatal day 33 animals were given twice daily administrations of nicotine (0.5 mg/kg free base). After the first of the daily injections they were placed in a locomotor arena every other day for behavioral testing.

Knowledge Of The Effects Of Alcohol On Fetal Development Among Women Of Childbearing Age., Mary Bales

Undergraduate Honors Theses

While Fetal Alcohol Syndrome Disorder is a recognized problem with alcohol ingestion during the formation of facial features, Fetal Alcohol Spectrum Disorders are not as widely recognized. These disorders result from exposure to alcohol throughout pregnancy when the brain and nervous system are developing. The resulting disorders include attention deficit disorders, social disorders, inappropriate behaviors, learning disorders, and intellectual disability. The incidence of children with alcohol-related disorders is increasing as evidenced by children needing special services in the educational systems. It is unknown how much alcohol ingestion is safe during pregnancy or how genetic factors are involved in the development …

The purpose of this project was to identify and develop tools that provide parents and other family members with the opportunity to learn ways to incorporate themselves as a support system for a grieving child in their family. Children express their feelings by showing rather than telling. Creativity allows bereaved children …

Hydrographic Controls And Seasonal Variability On The Carbonate System In The Northern Gulf Of Alaska, Kristen L. Shake

Marine Biology

The Northern Gulf of Alaska (GOA) supports a dynamic and economically viable marine ecosystem. One notable potential stressor to this ecosystem is ocean acidification (OA), a byproduct of the increased uptake of anthropogenic carbon dioxide (CO₂) by the ocean. Measurements of dissolved inorganic carbon (DIC) and total alkalinity (TA) were made along the continental shelf of the northern GOA and in Prince William Sound (PWS) and used to calculate seawater pH and the saturation state of aragonite Warp). Observations showed a high degree of seasonal variability in DIC concentrations in surface and bottom waters. TA was depleted relative to DIC …

Free Clinics And The Uninsured: The Need For Remote Area Medical In Central Appalachia After Health Reform., James W. Watson

Electronic Theses and Dissertations

In 2008, the election of President Barack Obama brought health care to the forefront of national discussions and led to the passage of the Patient Protection and Affordable Care Act (ACA). The legislation changed the rules of health care delivery in the United States, but the ACA did not do one fundamental thing: It did not end the need for many of the nation's most needy patients to seek free medical care from groups such as Remote Area Medical (RAM).

A mobile clinic, RAM brings together volunteer dentists, physicians, nurses, and other professionals as well as support staff for multi-day …

Mesoporous Functionalized Materials For Post-Combustion Carbon Dioxide Capture., Kolade Omoniyi Ojo

Electronic Theses and Dissertations

Novel highly functionalized hybrid organic-inorganic materials were synthesized by polycondensation of bis[3-(trimethoxysilyl)propyl]amine in presence of cationic and anionic surfactants. Reaction media strongly affected gelation time. Thus, in basic media gelation occurred immediately while acid increased gelation time. Material structures were studied by IR spectroscopy, porosimetry, XRD, and SAXS methods. In spite of the absence of an inorganic linker, obtained bridged silsesquioxanes had mesoporous structure. A material prepared in the presence of dodecylamine as a template had higher surface area and narrow pore size distribution while the use of sodium dodecylbenzene sulfate resulted in formation of mesopores with wide size ranges. …

Talking Heads: How Broadcast Media Frame The Public Relations Industry., Samara Rose Litvack

Electronic Theses and Dissertations

Researchers conducted a content analysis to measure framing of the public relations industry in 354 English language broadcast transcripts from the United States, Canada, and Australia from Sept. 1, 2009 to Aug. 31, 2010.

The overall tone toward public relations was strongly negative. Mentions reflected one-way forms of communication and mentions of the pejorative term "PR" appeared more frequently than mentions of "public relations". The profession was almost always mentioned within the body of the broadcast, as opposed to the headline or the lead paragraph.

Exploratory research showed 15 shows that included negative mentions 100% of the time. Additionally, 27 …

The Digital Folklore Project: Tracking The Oral Tradition On The World Wide Web., Jasen Bacon

Electronic Theses and Dissertations

I collected forty-two e-mail forwards over the course of four months, and from those I formulated a framework that adapts existing theory in collection and study of real-world folklore to the emerging folk communities that exist on the internet. Through this analysis I prove that the same genres of folklore that is routinely collected by folklorists have been adapted to fit the digital environment of the internet. I then use the framework that I lay out to perform a study of the e-mails themselves.

Investing In Citizenship: Free Men Of Color Of Color And The Case Against Citizens Bank ~ Antebellum Louisiana, Hannah J. Francis

LSU New Orleans Theses and Dissertations

Despite the popularity of free people of color in New Orleans as a research topic, the history of free people of color remains misunderstood. The prevailing view of free people of color is that of people who: engaged in plaçage, attended quadroon balls, were desperately dependent upon the dominant population, and were uninterested or afraid to garner rights for themselves. Contemporary historians have endeavored to amend this stereotypical perception; this study aims to be a part of the trend of revisionist history through an in-depth analysis of the co-plaintiffs in Boisdoré and Goulé, f.p.c., v. Citizens Bank and …

Voluntary Environmental Programs: An Examination Of Program Performance And The Role Of Institutional Design, Jessica Ll Sims

LSU New Orleans Theses and Dissertations

Many studies exist on whether Voluntary Environmental Programs (VEPs) improve firms’ environmental performance. Furthermore, the literature on VEPs theorizes that specific features contribute to program performance. This study examines the ability of Voluntary Environmental Programs to reduce emissions and the role of institutional design on their performance. Specifically, this study aimed to identify if specific features influence performance more than others do. The indicator of performance focuses on the overall emission reductions of firms across years 2007-2009. To analyze performance and features, the study examines the emission data and design features of each program. The results reveal the ability of …

Contextual Risk And The Association Between Sensitive Parenting And Social Competence During Early Childhood, Moira R. Riley

LSU New Orleans Theses and Dissertations

Both contextual risk and sensitive parenting have been associated with children’s social skills in early childhood (Brody, Stoneman, Smith & Gibson, 1999; Connell & Prinz, 2002; Oravecz, Koblinsky & Randolph, 2008, Trentacosta, 2008). However, it is not clear how sensitive parenting might impact children’s social skill development in the context of accumulation of risk. The current study tests two possible models. The first model, based on Rutters’ (1979) tests the theory that cumulative risk may moderate the relationship between sensitive parenting and social skills. The second model based on The Family Stress model (Conger, Conger, Elder, Lorenz, Simons & Whitbeck, …

Land Use Planning After A Natural Disaster, Walter E. Lundin

LSU New Orleans Theses and Dissertations

Recovery from a natural disaster is difficult, expensive, and can take ten years or more. Many contend that recovery planning can be ordered, knowable, and predictable and that the destruction of buildings and displacement of the population provide an opportunity to build back better. This thesis examines the complexity of recovery through the lens of land use planning. Land use planning serves as the central focus because land provides an individual or family their livelihood and its use underlies the economy. The thesis considers two planning models -- rational comprehensive and incremental. The thesis concludes that incremental planning is more …

Terrestrial Invertebrate Prey For Juvenile Chinook Salmon: Abundance And Environmental Controls In An Interior Alaska River, Laura Gutierrez

Biological Sciences

Terrestrial prey subsidies can be a key food source for stream fish, but their importance and environmental controls on their abundance have not been widely documented in high latitude ecosystems. This study investigated terrestrial invertebrate prey availability and predation by age-0+ juvenile chinook salmon (Oncorhynchus tshawytscha), overlap between terrestrial infall and drift to diet, and the relationship between diet to stream temperature and discharge in the Chena River, Interior Alaska. Terrestrial infall, drift, and juvenile chinook diet varied widely through the summers (May-September) of 2008 and 2009. Drift was comprised of 33% terrestrial and 67% aquatic invertebrate mass, while juvenile …

Reproductive Ecology And Morphometric Subspecies Comparisons Of Dunlin (Calidris Alpina), An Arctic Shorebird, Heather River Gates

Biological Sciences

The Arctic region provides globally important breeding and migratory habitat for abundant wildlife populations including migratory shorebirds. Due to their remote breeding locations, basic information on breeding ecology, annual productivity, and factors that regulate their populations are poorly studied. Wildlife biologists managing migratory bird populations require detailed information on avian breeding biology, in addition to information on migration ecology including connectivity of migratory stopover and wintering locations. To address information gaps in fecundity, I conducted an experimental study investigating the renesting ecology of Dunlin (Calidris alpina arcticola) by removing clutches at two stages of incubation and by following adults marked …

Novel Fungal Taxa In An Alaskan Boreal Forest: Phylogenetic Affinities, Ecologies, And Ribosomal Rna Secondary Structures, Daniel Glass

Biological Sciences

Phylogenetic analyses suggest that a novel DNA sequence (NS1) found in a boreal forest soil-clone library belongs to the fungal kingdom but does not fall unambiguously within any known class. In order to determine if NS1 codes for an authentic ribosomal RNA (rRNA) gene-copy, I modeled ribosomal RNA secondary structure for four gene regions. Such analyses have never been used on environmental ribosomal sequences before. It appears that NS1 does code for an authentic gene-copy and is not a biological or lab artifact. I also elucidated the habitat preferences, horizon preferences, and fine-scale spatial structure of NS1 using molecular methods. …

Clinical Coverage Of An Archetype Repository Over Snomed-Ct., Sheng Yu, Damon Berry, Jesus Bisbal

Articles

Clinical archetypes provide a means for health professionals to design what should be communicated as part of an Electronic Health Record (EHR). An ever-growing number of archetype definitions follow this health information modelling approach, and this international archetype resource will eventually cover a large number of clinical concepts. On the other hand, clinical terminology systems that can be referenced by archetypes also have a wide coverage over many types of health-care information.

No existing work measures the clinical content coverage of archetypes using terminology systems as a metric. Archetype authors require guidance to identify under-covered clinical areas that may need …

Oscar James Dunn: A Case Study In Race & Politics In Reconstruction Louisiana, Brian Mitchell

LSU New Orleans Theses and Dissertations

The study of African American Reconstruction leadership has presented a variety of unique challenges for modern historians who struggle to piece together the lives of men, who prior to the Civil War, had little political identity. The scant amounts of primary source data in regard to these leaders’ lives before the war, the destruction of many documents in regard to their leadership following the Reconstruction Era, and the treatment of these figures by historians prior to the Revisionist movement have left this body of extremely important political figures largely unexplored. This dissertation will examine the life of one of Louisiana’s …

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 …
