Effect Of Perceptual Interference And Response Conflict On P300 Latency, Yu-Shen Huang, Fen-Fen Chen

Rehabilitation Practice and Science

Background: The latency of the P300 component of the event related-potential (ERP) is an index of stimulus classification speed. In this study, we assessed the mental chronometry of stimulus discrimination and decision execution by study the effect of congruence visual stimuli and and compatibility on ERP and reaction time.Methods: The reaction time was divided into two sections based on the peak amplitude of P300. P300 latency was defined as the discrimination time needed to interpret the stimulus. The time from the peak of P300 to the initiation of movement was defined as duration of response selection. We hypothesized that congruency …

Can Tax Expenditure Analysis Be Divorced From A Normative Tax Base?: A Critique Of The 'New Paradigm' And Its Denouement, J. Clifton Fleming Jr., Robert J. Peroni

Faculty Scholarship

Tax expenditure analysis (TEA) requires a baseline for identifying tax provisions that provide subsidies or incentives instead of serving to define the tax base and to implement the tax. With respect to the federal income tax, the baseline historically has been the Schanz-Haig-Simons (SHS) definition of income with a few modifications. Critics have continuously and strongly attacked TEA by characterizing the SHS baseline as unprincipled, imprecise, and insufficiently related to our hybrid income/consumption tax system as it actually exists. Since the baseline is hopelessly defective, so the critics argue, TEA is fatally dysfunctional and the results of its application to …

Design And Synthesis Of Beta-Hairpin Peptidomimetics For Modulating Integrin Mediated Cell Adhesion, Abeta Fibrillogenesis And P53-Mdm2 Protein-Protein Interactions, Priyesh Jain

USF Tampa Graduate Theses and Dissertations

Inhibiting therapeutically important protein-protein interactions has been a tremendous challenge for medicinal chemists. The folded 3D structures of peptides and proteins, mainly comprise secondary structural elements i.e α-helices and β-sheet have created an opportunity to design small molecules and peptidomimetic inhibitors of protein-protein interaction (PPI). Hence, information about the formation and stabilization of these secondary structures is vital for designing future drugs. In this dissertation, several cyclic beta-hairpin peptidomimetics that mimic the recognition surface have been designed and synthesized as inhibitors for different targets such as integrin mediated extracellular matrix -cell adhesion in multiple myeloma, p53-MDM2 PPI, amyloid beta fibrillogenesis …

Evaluation Of Common Inherited Variants In Mitochondrial-Related And Microrna-Related Genes As Novel Risk Factors For Ovarian Cancer, Jennifer Permuth Wey

USF Tampa Graduate Theses and Dissertations

Epithelial ovarian cancer (EOC) is a leading cause of morbidity and mortality among women in the United States, and the etiology is incompletely understood. Common, low penetrant genetic variants such as single nucleotide polymorphisms (SNPs) likely contribute to a significant proportion of EOC. We examined whether SNPs in two understudied yet biologically important types of genes, mitochondrial-related and miRNA-related genes, may contribute to EOC susceptibility using data from a large, homogeneous study population of 1,815 EOC cases and 1,900 controls (frequency-matched on age-group and race/ethnicity) genotyped through stage 1 of an ongoing genome-wide association study. Inter-individual variation in genes involved …

Epidemiological Study Of Contributing Factors In The Development Of Peptic Ulcer And Gastric Cancer Initiated By Helicobacter Pylori Infection In India, Rahul Suresh Mhaskar

USF Tampa Graduate Theses and Dissertations

Background: Helicobacter pylori (H. pylori) infection is a significant risk factor for peptic ulcer (PU) and gastric cancer (GC). Apart from the virulent CagA genotype of H. pylori environmental and dietary factors influence disease outcomes. There have been no studies addressing these factors in Western India. Hence, we conducted a case control study enrolling PU, GC patients and controls at Pune, India.

Methods: Risk factors for PU and H. pylori infection were assessed in participant interview. H. pylori status was assessed from stool by monoclonal antigen detection. To understand treatment effect, we followed 100 H. pylori positive patients.

Results: We …

Antecedents And Consequences Of Channel Alienation: An Empirical Investigation Within Franchised Channels Of Distribution, Ivan Lapuka

USF Tampa Graduate Theses and Dissertations

Investigating an important overlooked phase of interorganizational relationship evolution, which is currently hypothesized to progress through five stages of awareness, exploration, expansion, commitment, and dissolution, this dissertation proposes that in the long road between commitment and dissolution, the quintessential interfirm relationship is likely to be characterized by aprolonged period of relationship alienation, which then becomes the immediate precursor to the dissolution stage.

The dissertation utilizes social learning theory, behavior constraint theory, and alienation theory to explain apathetic behaviors of franchisees. The principal proposition is that certain characteristics of the franchise system’s operating environment inadvertently condition franchisee estrangement and failure, and …

Effects Of Mulching, Fertilizer, Seeding And Seedling Treatments On Plant Species Recovery In Kondoa Irangi Hills, Tanzania, H. V. M. Lyaruu

Tanzania Journal of Science

Fertilization, mulching, imported seed bank seeding and seedlings were applied to triplicates of 1m x1m plots at Chakwe and Gubali sites in Kondoa Irangi Hills, Tanzania. Responses tested were seedling recruitment, species turnover, species’ biomass, mortality of seedlings, total number of perennial and woody species recruited and leguminous species. There were high significant correlations of 0.85 and 0.87 between seedling recruitment and mortality in both sites, indicating that other factors, probably aridity, rather than prevailing site conditions were likely to be important determinants of mortality. Inorganic fertilization was not an efficient means of improving short-term productivity, seedling recruitment or increased …

Acetate Causes Alcohol Hangover Headache In Rats, Christina R. Maxwell, Rebecca Jay Spangenberg, Jan B. Hoek, Stephen D. Silberstein, Michael L. Oshinsky

Department of Neurology Faculty Papers

Background

The mechanism of veisalgia cephalgia or hangover headache is unknown. Despite a lack of mechanistic studies, there are a number of theories positing congeners, dehydration, or the ethanol metabolite acetaldehyde as causes of hangover headache.

Methods

We used a chronic headache model to examine how pure ethanol produces increased sensitivity for nociceptive behaviors in normally hydrated rats.

Results

Ethanol initially decreased sensitivity to mechanical stimuli on the face (analgesia), followed 4 to 6 hours later by inflammatory pain. Inhibiting alcohol dehydrogenase extended the analgesia whereas inhibiting aldehyde dehydrogenase decreased analgesia. Neither treatment had nociceptive effects. Direct administration of acetate …

Oracle And Multiple Robustness Properties Of Survey Calibration Estimator In Missing Response Problem, Kwun Chuen Gary Chan

UW Biostatistics Working Paper Series

In the presence of missing response, reweighting the complete case subsample by the inverse of nonmissing probability is both intuitive and easy to implement. However, inverse probability weighting is not efficient in general and is not robust against misspecification of the missing probability model. Calibration was developed by survey statisticians for improving efficiency of inverse probability weighting estimators when population totals of auxiliary variables are known and when inclusion probability is known by design. In missing data problem we can calibrate auxiliary variables in the complete case subsample to the full sample. However, the inclusion probability is unknown in general …

Modification And Improvement Of Empirical Likelihood For Missing Response Problem, Kwun Chuen Gary Chan

UW Biostatistics Working Paper Series

An empirical likelihood (EL) estimator was proposed by Qin and Zhang (2007) for a missing response problem under a missing at random assumption. They showed by simulation studies that the finite sample performance of EL estimator is better than some existing estimators. However, the empirical likelihood estimator does not have a uniformly smaller asymptotic variance than other estimators in general. We consider several modifications to the empirical likelihood estimator and show that the proposed estimator dominates the empirical likelihood estimator and several other existing estimators in terms of asymptotic efficiencies. The proposed estimator also attains the minimum asymptotic variance among …

Spatial Distribution Of Calcium-Gated Chloride Channels In Olfactory Cilia, Donald A. French, Dorjsuren Badamdorj, Steven J. Kleene

Mathematical Sciences Faculty Research

Background

In vertebrate olfactory receptor neurons, sensory cilia transduce odor stimuli into changes in neuronal membrane potential. The voltage changes are primarily caused by the sequential openings of two types of channel: a cyclic-nucleotide-gated (CNG) cationic channel and a calcium-gated chloride channel. In frog, the cilia are 25 to 200 µm in length, so the spatial distributions of the channels may be an important determinant of odor sensitivity.

Principal Findings

To determine the spatial distribution of the chloride channels, we recorded from single cilia as calcium was allowed to diffuse down the length of the cilium and activate the channels. …

Measurements Of The Electric Form Factor Of The Neutron Up To Q(2)=3.4 Gev2 Using The Reaction (3)(He)Over-Right-Arrowe((E)Over-Right-Arrow, E ' N)Pp, S. Riordan, Timothy Holmstrom

Chemistry & Physics Faculty Publications

The electric form factor of the neutron was determined from studies of the reaction ³He⃗(e⃗,e^′n)pp in quasielastic kinematics in Hall A at Jefferson Lab. Longitudinally polarized electrons were scattered off a polarized target in which the nuclear polarization was oriented perpendicular to the momentum transfer. The scattered electrons were detected in a magnetic spectrometer in coincidence with neutrons that were registered in a large-solid-angle detector. More than doubling the Q² range over which it is known, we find G_Eⁿ=0.0236±0.0017(stat)±0.0026(syst), 0.0208±0.0024±0.0019, and 0.0147±0.0020±0.0014 for Q²=1.72, 2.48, and 3.41  GeV², respectively.

Jack - Height Adjustable Office Desk Mechanism, John Walsh

Other

This mechanism was developed out of the increasing requirement for individual users to be able to adjust the height of their desk to an ergonomically correct position for their physicality. Sitting at a standard height desk (usually 720-740mm) for long durations has been linked to health problems, including back and posture problems and DVT, for those who fall either side of the average user in terms of anthropometric height range. A typical problem with "systems furniture" which is widely installed in most corporate open-plan offices is that components are "shared" for cost, functionality and aesthetic purposes. Typically, this means that …

Next-To-Next-To-Leading Soft-Gluon Corrections For The Top Quark Cross Section And Transverse Momentum Distribution, Nikolaos Kidonakis

Faculty Articles

I present results for top quark production in hadronic collisions at LHC and Tevatron energies. The soft-gluon corrections to the differential cross section are resummed at next-to-next-to-leading-logarithm accuracy via the two-loop soft anomalous dimension matrices. Approximate next-to-next-to-leading-order differential and total cross sections are calculated. Detailed theoretical predictions are shown for the t (t) over bar cross section and the top quark p(T) distribution at the Tevatron and the LHC.
