Practitioners Or Researchers: Ed.D. Or Ph.D.? An Analysis Of Educational Leadership Doctoral Programs, Michael Dwyane Kennedy Jr.

Dissertations

This mostly descriptive study was conducted to analyze differences in doctoral degrees in educational leadership programs across the United States based on U.S. News and World Report (2011) rankings for Graduate Schools of Education. Specifically, this study explored admission, program, and final requirements as well as curriculum and faculty roles to determine the trends that have been evolving, increasing, decreasing, or remaining consistent in certain schools of the United States since the release of the Levine study of educational leadership programs in 2005. Five groups were used: 1) higher ranked 20; 2) lower ranked 20 graduate education schools; 3) top …

Development Of A Scale To Measure Local Residents' Perceived Social Impacts Of Hosting Large-Scale Sport Events, Wonyoung Kim

Dissertations

Existing studies have indicated that local residents‟ perceptions on both positive and negative social impacts toward hosting large-scale sport events have played as a key role for developing successful sport events based on getting community-wide support and involvement. However, examining local residents‟ perceived social impacts have been limited due to its intangible nature and lack of valid and reliable instrument for the adequate measurement. The purpose of this study was to explore a conceptual framework of social impacts and develop a valid and reliable instrument to measure local residents‟ perceived social impacts of hosting large-scale sport events. A preliminary questionnaire …

Genetic Associations With Borderline Personality Disorder And Related Traits And Behaviors, Casey Roy Guillot

Dissertations

Borderline personality disorder (BPD) and related traits and behaviors have been linked to a number of neurotransmitter systems, including serotonin, norepinephrine, GABA, and dopamine. Because three human single-nucleotide polymorphisms (SNPs), COMT rs4680, GABRA2 rs279871, and SNCA rs356195, have been linked to the abovementioned neurotransmitter systems, they may be associated with BPD and related traits and behaviors. The purpose of the current study is to examine associations of COMT rs4680, GABRA2 rs279871, and SNCA rs356195 with both categorical and continuous measures of BPD and with continuous measures of impulse control and self-harm in a nonclinical sample. Healthy volunteers were categorized into …

Evaluation Of Performance-Based And Pre-Set Conventional Criterion For Reinforcement In Check In-Check Out, Lauren Lestremau Harpole

Dissertations

The purpose of the present study was to compare the effectiveness of two methods of criterion-setting, performance-based or pre-set conventional, as evidenced by improvements in children’s behavior. Participant behavior was evaluated through teacher reports of appropriate behavior and observed academically engaged behavior as well as decreases in problem behavior and disruptive behavior. Eight elementary school students in a Southeastern town referred for exhibiting behavior problems served as participants in addition to their teachers. The effects of the different methods of criterion setting on the dependent variables were evaluated. Teacher ratings of appropriate behavior were assessed through evaluation of Daily Behavior …

Leptospiral Hemolysins Induce Proinflammatory Cytokines Through Toll-Like Receptor 2-And 4-Mediated Jnk And Nf-Κb Signaling Pathways, Huan Wang, Yifei Hu, David M. Ojcius, X. Frank Yang, Chenglin Zhang, Shibiao Ding, Xu'ai Lin, Jie Yan

All Dugoni School of Dentistry Faculty Articles

Infection with pathogenic Leptospira species causes serious systemic inflammation in patients. Although a few leptospiral proinflammatory molecules have been identified, Leptospira likely encodes other unidentified strong inflammation stimulators. The pathogenic L. interrogans genome encodes numerous putative hemolysin genes. Since hemolysins from other bacteria can cause inflammatory reactions, we hypothesized that leptospiral hemolysins may function as proinflammatory stimulators that contribute to the strong inflammation associated with Leptospira infection.

Influence Of Coffee Vermicompost On Growth And Nutrient Quality Of Greenhouse Spinach And Field Grown Green Bell Peppers, April Lorraine Vigardt

Theses

The vermicomposting of coffee grounds shows great promise for urban areas and university campuses. Several studies have examined using coffee grounds as a substrate for vermicomposting, however, little is known about its effect on plant growth, yield and quality. Therefore, two studies were conducted to assess these effects on greenhouse spinach and field grown bell peppers. Coffee vermicompost (VC) was utilized in a greenhouse spinach study over two spring growing seasons (2011 and 2012). Coffee VC was added to a 1:1:1 (peat, soil, sand) medium by volume (0, 25, 50 and 75%) in 4.5 L clay pots and seeded with …

Do Large, Infrequent Disturbances Release Estuarine Wetlands From Coastal Squeezing?, Jesse Fruchter

Theses

As disturbance frequencies, intensities, and types have changed and continue to change in response to changing climate and land-use patterns, coastal communities undergo shifts in both species composition and dominant vegetation type. Over the past 100 years, fire suppression throughout the Northern Gulf of Mexico coast has resulted in shifts towards woody species dominance at the expense of marsh cover. Over the next 100 years, sea levels will rise and tropical storm activity is projected to increase; resultant changes in salinity could reduce cover of salt-intolerant fresh marsh species. Together, the effects of fire suppression upslope and rising salinities downslope …

Positron Emission Tomography Utilization Development In Hong Kong, Steve Sitt

Theses

The introduction of clinical Positron Emission Tomography (PET) in oncology in the 1990s has substantially changed the management of patients with cancer and become one of the diagnostic modalities with the fastest growth worldwide (Buck et al., 2010). The major hurdle delaying the proliferation of PET was partly due to its high initial investment and insufficient third-party reimbursement (Keppler & Conti, 2001). Hong Kong, a region with about half the economic strength of Germany, was able to sustain a higher ratio of PET-CT scanners than that of Germany. Through the study of the PET utilization in Hong Kong, this research …

Late Spring Survey And Richness Estimation Of The Aquatic Benthic Insect Community In The Upper Portion Of The Lusk Creek Watershed, Jacqueline Turner

Theses

The Lusk Creek Watershed, located in Pope County, IL, long has been recognized as a high quality area and as biologically significant. Yet, surveys of the macroinvertebrate fauna have been limited. Thus, a survey of the benthic insect community in the upper portion of Lusk Creek was conducted from May 2003 to April 2005. Eleven sites were selected and characterized by physical properties and water chemistry. Insect distribution patterns, abundance, and diversity (richness, evenness) were examined. A total of 20,888 specimens, mostly immatures, were examined during the study and represented eight orders. The Diptera, by far, was the most common …

State-Induced Famine And Penal Starvation In North Korea, Rhoda E. Howard-Hassmann

Genocide Studies and Prevention: An International Journal

This article discusses North Korea as a case of state-induced famine, or faminogenesis. A famine from 1994 to 2000 killed 3–5% of North Korea’s population, and mass hunger reappeared in 2010– 2012, despite reforms meant to address the shortage of food. In addition, a prison population of about 200,000 people is systematically deprived of food; this might be considered penal starvation. There seems little recourse under international law to punish the perpetrators of state-induced fam- ine and penal starvation. State-induced famine does, however, fit some of the criteria of genocide in the United Nations Convention against Genocide, and could also …

Thy Brother’S Keeper? The Relationship Between Social Distance And Intensity Of Dehumanization During Genocide, Lisa Haagensen, Marnix Croes

Genocide Studies and Prevention: An International Journal

This paper puts forth the hypothesis that the degree of social distance between perpetrator and vic- tim groups prior to the outbreak of genocide is inversely related to the degree of severity of dehu- manization employed by the perpetrator group during genocide. Derived from psychological theory, this hypothesis is illustrated by using a primarily literature-based method of analysis combined with a vignette-designed severity of dehumanization scale. Three genocides are compared: the Rwandan Genocide, the Holocaust as it occurred in Western Europe, and the Holocaust as it occurred in East- ern Europe. The findings for Rwanda and the Holocaust in Eastern …

The Consumption Of Dha During Embryogenesis As An Indicative Of The Need To Supply Dha During Early Larval Development: A Review, Joana Figueiredo, Junda Lin, Justin Anto, Luis Narciso

Ocean Engineering and Marine Sciences Faculty Publications

The establishment of an adequate larval diet for crustacean and fish often involves a series of time-consuming and expensive trial and errors. Despite being nutritionally poor, rotifers and Artemia are the most commonly used preys in larviculture. Whether (and to what extent) the prey needs to be enriched with essential fatty acids differs from species to species. We hypothesized that the DHA content of a newly spawned eggs and its consumption through embryogenesis can be a good indicator of the need to enrich the prey with DHA. In order to assess this hypothesis, we performed a search in the scientifc …

Investigation Of Enhancement Of Furosemide Solubilization With Cyclodextrins And A Novel Octenyl Succinate Anhydride Starch, Rui Zhu

Theses and Dissertations (ETD)

Solubility behavior is one of the most challenging aspects for drug commercialization and often the main reason of drug that do not reach to its full potential. Now nearly 60% new chemical entities possess solubility problems, whereas practically no drug products with less than 10 µg/ml solubility in 70’s or 80’s. There is an ever increasing need to develop new formulation techniques and exicipients with novel mechanisms of action. Various techniques have been applied to enhance the drug solubility such as co-solvents, particle size reduction, lipid based drug delivery systems, nanosuspension, use of surfactants, salt formation, cyclodextrin complexes and solid …

Against All Odds: Relations Between Nato And The Mena Region, Florence Gaub Dr.

Books, Monographs & Collaborative Studies

While NATO was created with a primary outlook to the East, its Southern rim was neglected strategically until the end of the Cold War. Since then, the Alliance has undertaken a number of efforts to build strategic relationships with the Middle East and North Africa, recognizing the region’s importance for Allied security. However, looming obstacles may well interfer with NATO's efforts to enhance relations with the region. Geostrategic realities are not in NATO’s favor: it is a region of crisis; suspicious of the West in general; riddled with internal instability; and is a difficult to build ties with. This monograph …

Objective—To characterize mucosal gene expression in dogs with chronic enteropathy (CE). Animals—18 dogs with CE and 6 healthy control dogs.

Procedures—Small intestinal mucosal biopsy specimens were endoscopically obtained from dogs. Disease severity in dogs with CE was determined via inflammatory bowel index scores and histologic grading of biopsy specimens. Total RNA was extracted from biopsy specimens and microchip array analysis (approx 43,000 probe sets) and quantitative reverse transcriptase PCR assays were performed.

Results—1,875 genes were differentially expressed between dogs with CE and healthy control dogs; 1,582 (85%) genes were downregulated in dogs with CE, including neurotensin, fatty …

Melanopsin Mediates Retrograde Visual Signaling In The Retina, Dao-Qi Zhang, Michael A. Belenky, Patricia J. Sollars, Gary E. Pickard, Douglas G. Mcmahon

School of Veterinary and Biomedical Sciences: Faculty Publications

The canonical flow of visual signals proceeds from outer to inner retina (photoreceptors→bipolar cells→ganglion cells). However, melanopsin-expressing ganglion cells are photosensitive and functional sustained light signaling to retinal dopaminergic interneurons persists in the absence of rods and cones. Here we show that the sustained-type light response of retinal dopamine neurons requires melanopsin and that the response is mediated by AMPA-type glutamate receptors, defining a retrograde retinal visual signaling pathway that fully reverses the usual flow of light signals in retinal circuits.

Economic Impact Of Double-Crested Cormorant, Phalacrocorax Auritus, Depredation On Channel Catfish, Ictalurus Punctatus, Aquaculture In Mississippi, Usa, Brian S. Dorr, Loren Wes Burger Jr, Scott Barras, Kristina Casscles-Godwin

United States Department of Agriculture Wildlife Services: Staff Publications

The Yazoo River Basin of Mississippi, USA, supports the largest concentration of hectares devoted to channel catfish, Ictalurus punctatus, aquaculture production in North America. The Yazoo Basin also supports large numbers of resident, wintering and migrating fish-eating birds, with the Doublecrested Cormorant, Phalacrocorax auritus, implicated as the most serious depredating species. We used data from aerial surveys of numbers and distribution of cormorants in the Yazoo Basin and on commercial catfish ponds during winters (November–April) 2000–2001 and 2003–2004 to refine estimates of regional economic losses due to cormorant depredation. In both periods, the greatest monthly estimates of cormorant …

Quorum Sensing And Other Aspects Of The Biology Of Candida Albicans, Kenneth W. Nickerson

Kenneth Nickerson Papers

Most dimorphic fungi exhibit cell density dependent effects in that they grow as yeasts when inoculated at > 10⁶ cells per ml and as mycelia when inoculated at < 10⁶ cells per ml. For Candida albicans, we discovered (2001) that this phenomenon (quorum sensing) is due to the production and secretion of the C₁₅ isoprenoid trans-trans farnesol. Since then, we found that C. albicans cells treated with sublethal levels of zaragozic acid (2003) or fluconazole (2004) produced 10-40X more farnesol and that these fluconazole treated cells were ca. 5X more toxic to mice following tail vein injection. This suggestion …

13C Nmr Reveals No Evidence Of N–Π* Interactions In Proteins, Bradley Worley, Georgia Richard, Gerard S. Harbison, Robert Powers

Department of Chemistry: Faculty Publications

An n ‒ Π* interaction between neighboring carbonyl groups has been postulated to stabilize protein structures. Such an interaction would affect the ¹³C chemical shielding of the carbonyl groups, whose paramagnetic component is dominated by n ‒ Π* and Π ‒ Π* excitations. Model compound calculations indicate that both the interaction energetics and the chemical shielding of the carbonyl group are instead dominated by a classical dipole-dipole interaction. A set of high resolution protein structures with associated carbonyl ¹³C chemical shift assignments verifies this correlation and provides no evidence for an inter-carbonyl n ‒ Π* interaction.

Management Of Invasive Coqui Frog Populations In Hawaii, William C. Pitt, Karen H. Beard, Rogelio E. Doratt

United States Department of Agriculture Wildlife Services: Staff Publications

During the last 25 years, two species of Eleutherodactylus frogs, coqui and greenhouse frogs, have become established in Hawaii and other Pacific Islands. Coqui frogs, Eleutherodactylus coqui, were introduced to Hawaii prior to 1988 via the horticultural trade (Kraus & Campbell 2002). Since their introduction, the number and size of coqui frog infestations have rapidly increased and frogs have spread throughout the four main Hawaiian Islands with the largest infestation on the island of Hawaii. Coqui frogs are small (<65 mm in length) nocturnal tree frogs that are endemic to the island Puerto Rico (Beard et al. 2008). They are completely terrestrial and do not need open water for development because the frogs …

Mind The Gap: An Analysis Of The Function Of Love In The Works Of Tom Stoppard And C.S. Lewis., Jacqueline C. Lawler

Pell Scholars and Senior Theses

Writers C.S. Lewis and Tom Stoppard, though philosophically different, both write about love that embodies the natural law. The natural law can be defined as law that is inherent in man and can be discerned by reason rather than by revelation. Both writers use their observational style in order to reason their way to nearly identical laws of love. Stoppard’s The Invention of Love, Arcadia, Rock ‘n’ Roll and The Real Thing will be analyzed using the framework of C.S. Lewis’s book, The Four Loves.

The Prevention Of Victory: How The U.S. Government Crippled Support For The Iraq War, Jacob M. Petrarca

Pell Scholars and Senior Theses

Regulation Of Foxc2 Expression And Function During Epithelial-Mesenchymal Transition By Gsk-3Β, Maryam Shariati

Dissertations and Theses (Open Access)

Metastasis is the ultimate cause for the majority of cancer-related deaths. The forkhead box transcription factor FOXC2 is known to be involved in regulating metastasis as well as a variety of developmental processes, including the formation of lymphatic and cardiovascular systems. Previous studies have shown that FOXC2 protein is localized either in the nucleus and/or in the cytoplasm of human breast tumor cells. This pattern of localization is similar to that of another forkhead family member, FOXO3a. Additionally, localization of FOXO3a is known to be differentially regulated by upstream kinase AKT. Therefore, I investigated whether FOXC2 localization could also be …

A Classroom Experiment: Implementing A Math-Talk Environment In A University Setting, Janice Bodily

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

A need for reform in teaching mathematics has long been recognized. The traditional classroom with the sage on the stage lacks a higher level of engagement for the students and therefore, produces a lower level of student satisfaction. The math-talk classroom is one attempt to engage students and to raise the level of interaction and discussion, thus enabling students to increase their level of comprehension. In an effort to create a math-talk experience in my Calculus II course, I applied the methodology of Thinking Through a Lesson Protocol (TTLP) to test its effectiveness in assisting the instructor in creating an …

A Mechanistic Study Of Catalytic Promiscuity In Protein Phosphatase 1, Yuan Chu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

"Catalytic promiscuous" enzymes, which possess additional activities besides their "native" activity, albeit with a lower efficiency than the main reaction, have become a new frontier for biochemistry and have received considerable attention. Catalytic promiscuity has been suggested to contribute to enzyme evolution through the mechanism of gene duplication followed by specialization of one of the two copies for the new function. Mimicking this evolutionary shortcut could also provide a more efficient route to changing the function of proteins by directed evolution.

The promiscuous phosphatase PP1 is a member of the phosphoprotein phosphatase (PPP) gene family, which is critical for the …
