Rediscovering The Delta A Reassessment Of The Linkages Between Poverty, Economic Growth And Public Policy Using Geographically Weighted Regression Analysis, Dominique Duval-Diop

LSU Doctoral Dissertations

The nineties have witnessed broad economic growth and prosperity throughout the nation, with improvements in all major indicators of economic well-being. Yet, many rural and urban regions continued to experience economic distress during this period. At the same time, investments in infrastructure, human capital and poverty relief continue to be targeted to these failing areas. This work examines trends in demographic indicators, economic growth and federal funding experienced between 1990 and 2000 in the federally designated Mississippi Delta region in order to answer the following questions. What impact does federal funding have on poverty in the Mississippi Delta region overall? …

Residue Coevolution: Modeling And Interpretation, Zhengyuan Wang Jan 2006

Residue Coevolution: Modeling And Interpretation, Zhengyuan Wang

LSU Doctoral Dissertations

Coevolution between amino acid residues and its context-dependence are important for exploring protein structure and function, and critical for understanding protein structural and functional evolution. Coevolution has long been ignored because of its complexity and the lack of computing power. In the research presented here, I developed an efficient coevolution analysis methodology based on likelihood comparisons of statistical models. Likelihood ratios and Bayes factors, calculated using the Markov chain Monte Carlo algorithm, were employed as the statistics. Two types of models, 2-state and 3-state, were developed to allow for the context-dependence of coevolution. Computer programs implementing this methodology were coded …

Studies Of Pathogenesis-Related Proteins In The Strawberry Plant: Partial Purification Of A Chitinase-Containing Protein Complex And Analysis Of An Osmotin-Like Protein Gene, Yuhua Zhang Jan 2006

Studies Of Pathogenesis-Related Proteins In The Strawberry Plant: Partial Purification Of A Chitinase-Containing Protein Complex And Analysis Of An Osmotin-Like Protein Gene, Yuhua Zhang

LSU Doctoral Dissertations

Plant chitinases and osmotin-like proteins (OLPs) are both pathogenesis-related (PR) proteins, which are implicated in plant responses to pathogen attacks and environmental stresses. In this dissertation, a chitinase-containing protein complex was purified to near homogeneity from strawberry leaf extracts. This protein complex contained at least five different chitinase molecules as revealed by activity gel assays. A previous study showed that winter rye leaves contain seven protein complexes, which consist of various combinations of a chitinase, two glucanase-like proteins (GLPs) and a thaumatin-like protein (TLP). Western blot analysis of the strawberry chitinase complex, however, did not detect the presence of any …

The Multiple Dimensions Of The Interfirm Network: The Critical Sources Of Product Innovation, Thongchai Srivardhana Jan 2006

The Multiple Dimensions Of The Interfirm Network: The Critical Sources Of Product Innovation, Thongchai Srivardhana

LSU Doctoral Dissertations

This dissertation examines the impacts of interfirm variables on both invention and commercialization activities, following Greve’s (2003) suggestion that innovation research will be enriched if more studies integrate invention and commercialization activities to understand the entire innovation development process. Utilizing two established theoretical perspectives—organizational learning and institutional theory—six sets of hypotheses are developed containing the following interfirm variables: 1) direct and indirect ties, 2) strength of direct ties, 3) structural holes, 4) prominence of direct partners, 5) exploration and exploitation partners, and 6) horizontal and vertical networks. The dissertation also predicts that these interfirm variables would contribute to either invention …

Resonance Pacemakers In Excitable Media, Tabitha Ruvarashe Chigwada, P. Parmananda, Kenneth Showalter Jan 2006

Resonance Pacemakers In Excitable Media, Tabitha Ruvarashe Chigwada, P. Parmananda, Kenneth Showalter

Faculty & Staff Scholarship

Chemical waves are initiated in an excitable medium by resonance with local periodic forcing of the excitability. Experiments are carried out with a photosensitive Belousov-Zhabotinsky medium, in which the excitability is varied according to the intensity of the imposed illumination. Complex resonance patterns are exhibited as a function of the amplitude and frequency of the forcing. Local resonance-induced wave initiation transforms the medium globally from a quiescent excitable steady state to a periodic state of successive traveling waves.

W-Boson Production With Large Transverse Momentum At The Lhc, Nikolaos Kidonakis, Richard J. Gonsalves, Agustin Sabio Vera Jan 2006

W-Boson Production With Large Transverse Momentum At The Lhc, Nikolaos Kidonakis, Richard J. Gonsalves, Agustin Sabio Vera

Faculty Articles

We study W-boson production with large transverse momentum, QT, in pp collisions at the LHC. We calculate the complete NLO corrections and the soft-gluon NNLO corrections to the differential cross section. The NLO corrections are large but they do not reduce the scale dependence relative to LO, while the NNLO soft-gluon corrections, although small, significantly reduce the scale dependence and thus provide a more stable result.

Production Of Large Transverse Momentum W Bosons At The Tevatron, Nikolaos Kidonakis, Agustin Sabio Vera Jan 2006

Production Of Large Transverse Momentum W Bosons At The Tevatron, Nikolaos Kidonakis, Agustin Sabio Vera

Faculty Articles

We discuss the production of W bosons at large transverse momentum in p pbar collisions at the Tevatron Run I and II. W boson hadroproduction is a process of relevance in testing the Standard Model and in estimates of backgrounds to new physics. The next-to-leading order cross section in the region of large transverse momentum is dominated by threshold soft-gluon corrections which arise from incomplete cancellations near partonic threshold between graphs with real emission and virtual graphs due to the limited phase space available for real gluon emission. In this contribution it is shown how, by including next-to-next-to-leading-order (NNLO) soft-gluon …

The Strength And Structure Of The Galactic Center Magnetic Field, Ted La Rosa, Steven N. Shore, T. Joseph W. Lazio, Namir E. Kassim Jan 2006

The Strength And Structure Of The Galactic Center Magnetic Field, Ted La Rosa, Steven N. Shore, T. Joseph W. Lazio, Namir E. Kassim

Faculty Articles

This paper summarizes recently obtained, strong evidence for a weak global field in the Galactic center (GC): the existence of a large-scale region of diffuse, low-frequency, nonthermal emission coincident with the central molecular zone. The overall energetics of this emission, considered along with constraints on GC cosmic ray energy density and diffusion, indicate clearly that the magnetic field pervading this region is ∼ 10 μG. For completeness, additional points on the orientation of the GC nonthermal filaments, rotation measures of extragalactic sources seen through the GC, and comparison with other normal spiral galaxies are also reviewed.

"The Sad (Or Angry) Lament:" An Exposition Of African American Struggles With Issues Of Gender In Relationships Depicted Through Works Of Literature., Bethany Joy Conner Jan 2006

"The Sad (Or Angry) Lament:" An Exposition Of African American Struggles With Issues Of Gender In Relationships Depicted Through Works Of Literature., Bethany Joy Conner

Honors Theses

African-American gender roles have traditionally been problematic in regards to studying the effects of traditional western nonns upon the black community. The purpose of this work is to elaborate on the particular difficulties that African-American women face when confronted with rigid social constraints in relationships (platonic, romantic, and familial). African- American fictitious literature is adept at depicting the many and varied subtleties and complexities of African-American female experiences in relationships and presents an intriguing slant to this topic. Thus, this work is mostly based upon fiction by African-American female writers who deal directly with the effects of African-American gender roles. …

Pharmacological Dissociation Of Anxiety Model In The Chick Separation Stress Paradigm, Robert Thomas Wicks Jan 2006

Pharmacological Dissociation Of Anxiety Model In The Chick Separation Stress Paradigm, Robert Thomas Wicks

Honors Theses

The chick separation stress paradigm has been validated as an anxiolytic screening assay. However, whether the paradigm better models Panic Disorder (PD) or Generalized Anxiety Disorder (GAD) is unknown. To pharmacologically dissociate the chick separation stress paradigm as a model of PD or GAD, subjects were administered drug probes that were either: 1) only effective in the treatment of PD (phenelzine 3.125-25.0 mg/kg), 2) effective in the treatment of both PD and GAD (alprazolam 0.065-0.5 mg/kg; clonidine 0.1-0.25 mg/kg; imipramine 1.0-15.0mg/kg), 3) only effective in the treatment of GAD (buspirone 2.5-10.0 mg/kg; trazodone 0.1-3.0 mg/kg), or 4) capable of exacerbating …
