Brain Potentials Elicited By Prose-Embedded Linguistic Anomalies, Mark D. Allen, Kayo Inoue, Judith Mclaughlin, Lee Osterhout
Brain Potentials Elicited By Prose-Embedded Linguistic Anomalies, Mark D. Allen, Kayo Inoue, Judith Mclaughlin, Lee Osterhout
Faculty Publications
Linguistic theories distinguish between syntax (sentence form) and semantics (sentence meaning). Correspondingly, recent studies have shown that syntactic and semantic anomalies elicit distinct changes in the event-related brain potential (ERP). However, these results have been obtained with highly artificial methodologies and have not yet been generalized to more natural reading conditions. Here, we recorded ERPs while subjects read a naturalistic prose passage. The subjects either read for comprehension with no other task being assigned or read for comprehension and made acceptability judgments after each sentence. Consistent with prior work and regardless of the subjects’ assigned task, syntactic anomalies elicited a …

Early Component-Based Reliability Assessment Using Uml Based Software Models, William Black Smith V
Graduate Theses, Dissertations, and Problem Reports (ETD)
In the last decade, software has grown in complexity and size, while development timelines have diminished. As a result, component-based software engineering is becoming routine. Component-based software reliability assessment combines the architecture of the system with the reliability of the components to obtain the system reliability. This allows developers to produce a reliable system and testers to focus on the vulnerable areas.;This thesis discusses a tool developed to implement the methodology previously created for early reliability assessment of component-based systems. The tool, Early Component-based Reliability Assessment (ECRA), uses Rational Rose Unified Modeling Language (UML) diagrams to predict the reliability of …
Job Reallocation And Productivity Growth Under Alternative Economic Systems And Policies: Evidence From The Soviet Transition, J. David Brown, John S. Earle
Job Reallocation And Productivity Growth Under Alternative Economic Systems And Policies: Evidence From The Soviet Transition, J. David Brown, John S. Earle
Upjohn Institute Working Papers
How do economic policies and institutions affect job reallocation processes and their consequences for productivity growth? This paper studies the extreme case of economic system change and alternative transitional policies in the former Soviet Republics of Russia and Ukraine. Exploiting annual industrial census data from 1985 to 2000, we find that Soviet Russia displayed job flow behavior quite different from market economies, with very low rates of job reallocation that bore little relationship to relative productivity across firms and sectors. Since liberalization began, the pace, heterogeneity, and productivity effects of job flows have increased substantially. The increases occurred more quickly …
Thermodynamic Effects Of Phospholamban On Ca-Atpase Kinetics, Patrick L. Apopa
Thermodynamic Effects Of Phospholamban On Ca-Atpase Kinetics, Patrick L. Apopa
Graduate Theses, Dissertations, and Problem Reports (ETD)
The Ca-ATPase of sarcoplasmic reticulum removes cytosolic calcium to promote muscle relaxation. In the heart, the Ca-ATPase is regulated by phospholamban, which inhibits the Ca-ATPase by decreasing Ca-ATPase calcium sensitivity. However, the kinetic and thermodynamic mechanisms of inhibition are not understood. The purpose of this research was to test the hypothesis that phospholamban regulates Ca-ATPase kinetics by increasing Ca-ATPase activation energy. The baculovirus-insect cell expression system was used to produce samples containing Ca-ATPase alone or Ca-ATPase with phospholamban. The temperature-dependence of Ca-ATPase activity and catalytic site density was measured in the absence and presence of phospholamban at sub-saturating calcium and …

The results were found to be in good agreement. The imaging part of BILS was calibrated using a target with known dimensions.;The terminal velocities and particle sizes of near-spherical, Nu-pareil …
Three Essays On Data Contaminants, Outliers And Macroeconomic Time Series, Joseph Michael Palardy
Three Essays On Data Contaminants, Outliers And Macroeconomic Time Series, Joseph Michael Palardy
Graduate Theses, Dissertations, and Problem Reports (ETD)
This thesis illustrates the effects of outliers on forecasting and on simulated general equilibrium models. The first essay demonstrates that using robust-estimation techniques may greatly improve long-run autoregressive forecasts if the model to be estimated is generated from a heavy-tailed distribution. The second essay continues with a similar theme. It shows that in the context of random contamination models, automatic autoregressive selection criteria may be severely inaccurate. If the estimated model is misspecified, forecasting accuracy may be considerably reduced. Once again, robust-estimation techniques limit the influence of the aberrant data---in this case from the contaminating distribution. The third essay demonstrates …

Automation Of The Superpave Mix Design Process For The West Virginia Division Of Highways, Martin Felix Padula
Graduate Theses, Dissertations, and Problem Reports (ETD)
During the fifty years between 1940 and 1990, the nation's bituminous roadways were predominantly designed using either the Marshall or Hveem method. The Superior Performing Asphalt Pavements (Superpave)(TM) method was later developed to address the issues of increased traffic volumes and heavier loads on the nation's roadways. This new mix design process relies on volumetric calculations and graphs, which are cumbersome to perform by hand. There is no current public domain Superpave software package available which is independent of any commercial laboratory product and available to an asphalt mix designer.

Graduate Theses, Dissertations, and Problem Reports (ETD)
The major contribution of this study is to quantify the economic impact of Kuwait's membership in the World Trade Organization (WTO) on supply, demand, welfare and terms of trade. A general equilibrium international trade model is used to obtain quantitative results. The model is theoretically static and based on the assumptions of perfect competition and constant returns to scale. However, it was estimated and simulated dynamically.;After specifying the model theoretically it is estimated empirically by linearizing the supply and demand equations that were obtained from solving the model analytically. The estimated model is used in a number of simulation exercises …
Differentially Expressed Genes In The Mutualistic Neotyphodium Coenophialum-Tall Fescue Interaction, Linda Joy Johnson
Differentially Expressed Genes In The Mutualistic Neotyphodium Coenophialum-Tall Fescue Interaction, Linda Joy Johnson
Graduate Theses, Dissertations, and Problem Reports (ETD)
Tall fescue (Lolium arundinaceum), an agronomically important forage grass, is typically associated with a mutualistic asexual fungus Neotyphodium coenophialum. Endophytic fungal growth is confined to the intercellular spaces of the plant and induces no symptoms. The endophyte partner enhances its host's fitness by improving nutrient acquisition as well as by providing protection from various abiotic and biotic stresses. However, grass-endophyte partnerships are detrimental to grazing livestock, due to the production of an array of fungal alkaloids. To investigate this interaction at the molecular level, suppressive subtractive hybridization was used to identify differentially expressed genes from the symbiosis. In total, twenty-nine …

Is Ricardo's Essay On Profits A Precursor Of The New Trade Theory?, Hian Teck Hoon
Is Ricardo's Essay On Profits A Precursor Of The New Trade Theory?, Hian Teck Hoon
Research Collection School Of Economics
This paper carefully analyzes a passage of Ricardo’s Essay on Profits ([1815] 1923), which suggests that he clearly understood the effects of both interindustry as well as intraindustry trade. In the context of the Essay model, Ricardo argues that free interindustry trade involving an exchange of manufactures for agricultural good (from England’s point of view) raises the rate of profit through lowering the relative price of the agricultural good. On the other hand, where trade involves simply an exchange of manufactures for manufactures, these being produced under conditions of economies of scale (division of labour in manufactures (pg. 25 of …
Rubber Toughening Of Glass-Fiber -Reinforced Nylon 66, Fares D. Alsewailem
Rubber Toughening Of Glass-Fiber -Reinforced Nylon 66, Fares D. Alsewailem
Graduate Theses, Dissertations, and Problem Reports (ETD)
Glass fibers are commonly added to thermoplastics by the process of extrusion compounding for a variety of reasons, mainly to enhance their strength and make them dimensionally stable. Since the extruder has to be flushed out each time product composition is changed, a large amount of incompatible polymeric waste is generated. This waste material is usually landfilled even though the polymers contained in it are valuable and worth being recycled. It is the drastic reduction in mechanical properties resulting from polymer incompatibility which restricts their recycling. A good strategy of recycling thermoplastics calls for separating materials from each other before …

Mode I Fracture And Durability Of The Cfrp -Concrete Interface Bond, David Moses Boyajian
Graduate Theses, Dissertations, and Problem Reports (ETD)
The continual degradation of civil infrastructures worldwide has prompted the need for effective solutions, posing major challenges to those involved with reinforced concrete structures. Externally bonded fiber reinforced polymer (FRP) composites have proven to be an efficient means of rehabilitation and enhancement to both existing and new structures alike. An important issue regarding this technology that needs further exploration, however, is the strength and integrity of the interface bond---the inadequacy of which can result in premature failure of the reinforced member.;Until now, there were no available methods to rigorously evaluate the interface bond strength and integrity for concrete structures externally …
