Reasons For The Low Usage Of Scheduling Software And The Difference In Production Performance Between Users And Nonusers Of Scheduling Software From A Lean Manufacturing Perspective, Sandra Yveborg

Theses

It is more important than ever for printers to improve efficiency and productivity, and the means for doing so are available. Computer-assisted scheduling is one method that is claimed to increase throughput speed and reduce costs, among other benefits. Recently, scheduling applications have started to increase in popularity, and many management information systems (MISs) have built-in scheduling features. However, only 15% of the companies that own scheduling software utilize it. The first part of this research project seeks to determine the reasons for the low usage. Another way to increase efficiency is through Lean manufacturing, a strategy for eliminating non-value-added …

Shadows Over Goshen: Plain Whites, Progressives And Paternalism In The Depression South, Fred Carl Smith

Dissertations

This dissertation is about poverty and rural Southerners and the beginnings of America's rational assault on poverty. By 1932, a sense of emergency and desperation permeated American economic and political thinking. The apparent collapse of the industrial economy and credit markets created an environment in which politicians allowed and the public demanded bold experimentation. The period, 1933-1937, in which most of America approved or tolerated progressive notions, offered an opportunity for progressives to demonstrate their solutions to persistent southern poverty. The Division of Subsistence Homesteads (DSH), an agency of the Department of Interior, created communities that combined subsistence gardening with …

Metrics For Solar Wind Prediction Models: Comparison Of Empirical, Hybrid, And Physics‐Based Schemes With 8 Years Of L1 Observations, M. J. Owens, Harlan E. Spence, S. Mcgregor, W. J. Hughes, J. M. Quinn, C. N. Arge, P. Riley, J. Linker, D. Odstrcil

Physics & Astronomy

[1] Space weather effects on technological systems originate with energy carried from the Sun to the terrestrial environment by the solar wind. In this study, we present results of modeling of solar corona-heliosphere processes to predict solar wind conditions at the L1 Lagrangian point upstream of Earth. In particular we calculate performance metrics for (1) empirical, (2) hybrid empirical/physics-based, and (3) full physics-based coupled corona-heliosphere models over an 8-year period (1995–2002). L1 measurements of the radial solar wind speed are the primary basis for validation of the coronal and heliosphere models studied, though other solar wind parameters are also considered. …

Ambient Solar Wind's Effect On Icme Transit Times, A. W. Case, Harlan E. Spence, M. J. Owens, P. Riley, D. Odstrcil

Physics & Astronomy

[1] Most empirical and numerical models of Interplanetary Coronal Mass Ejection (ICME) propagation use the initial CME velocity as their primary, if not only, observational input. These models generally predict a wide spread of 1 AU transit times for ICMEs with the same initial velocity. We use a 3D coupled MHD model of the corona and heliosphere to determine the ambient solar wind's effect on the propagation of ICMEs from 30 solar radii to 1 AU. We quantitatively characterize this deceleration by the velocity of the upstream ambient solar wind. The effects of varying solar wind parameters on the ICME …

Prep Workshop Report: Expository Writing, Darren B. Glass

Math Faculty Publications

A significant part of the job of a mathematician involves writing - between research papers, expository writing, grant applications, letters of recommendation, and materials for our teaching, I know that I spend much of my days writing something or other. Yet most of us are never really trained to write mathematics, and even in our jobs we rarely find time to talk about the actual writing of the mathematics which has taken place. With this in mind, I chose to attend a PREP workshop held by the Mathematical Association of America at their headquarters in Washington, DC dedicated to the …

Specifying And Assessing Knowledge And Skills For Life, Geoff N. Masters

2008 – Touching the Future: Building Skills for Life and Work

In my presentation to this year’s Research Conference I will be taking as my starting point the proposition that a fundamental purpose of schooling is to provide every student with knowledge and skills to equip them for life beyond school. While acknowledging that schooling has broader purposes, I will argue that there are some fundamental understandings and skills that all students should develop during their school years, and that every student should be expected to demonstrate an acceptable level of these skills and understandings by the time they leave school.

The Emotional Intelligence And Resilience Of School Leaders: An Investigation Into Leadership Behaviors, Aileen Thompson Bumphus

Dissertations

Recent research suggests that leadership in schools and emotional intelligence are related. Furthermore, resiliency has been researched and found to be linked to successful leadership. As a result of these findings and the researcher's own professional experiences, it is speculated that emotional intelligence, resilience, and school leadership may be highly related factors in how one leads a school. The study of this three-factor relationship has been virtually overlooked in the research on school leadership and might prove useful in the recruitment, identification, development, and retention of effective school leaders.

A study of the emotional intelligence, resilience, and leadership of public …

A Spatial-Temporal Analysis Of Factors Influencing The Postsecondary Plans Of Indiana Public High School Graduates; 1996-2006, Anna Rosalie Carson

All-Inclusive List of Electronic Theses and Dissertations

Because a high school graduate's postsecondary expectations influence his or her chances of attaining a Bachelor's degree within eight years, this indicator deserves more consideration than it receives. Using survey results for the postsecondary educational plans of students graduated from Indiana public high schools between 1996 and 2006, this study identifies a typology of four significantly different patterns of postsecondary plans in Indiana school districts. Research literature in geography, political science, and education recognizes educational outcomes, family demographics, and school districts' financial and socioeconomic characteristics as factors that influence college attendance decisions. Many of them differ significantly by the typology …

Effect Of Long-Range Hopping On Tc In A Two-Dimensional Hubbard-Holstein Model Of The Cuprates, Ehsan Khatami, A. Macridin, M. Jarrell

Faculty Publications

We study the effect of long-range hoppings on Tc for the two-dimensional (2D) Hubbard model with and without Holstein phonons using parameters evaluated from band-structure calculations for cuprates. Employing the dynamical cluster approximation (DCA) with a quantum Monte Carlo (QMC) cluster solver for a 4-site cluster, we observe that without phonons, the long-range hoppings, t′ and t′′, generally suppress Tc. We argue that this trend remains valid for larger clusters. In the presence of the Holstein phonons, a finite t′ enhances Tc in the under-doped region for the hole-doped system, consistent with local-density approximation (LDA) calculations and experiment. This is …

Place Attachment And Recreational Constraints Relating To Fire Management, William W. Hendricks, Deborah J. Chavez, Kelly S. Bricker

Natural Resources Management and Environmental Sciences

This paper presents a study of visitors to the Big Sur region of California during summer 2001. An onsite survey was administered to visitors to USDA Forest Service day-use areas and at developed campgrounds. Place attachment, observations relating to fires and fire management, and perceived recreational constraints owing to wildland fire and fire management are examined. The results indicate that place dependence and place identity influence some perceived constraints and observations of fire conditions. A discussion of the findings is provided, emphasizing the importance of managers’ understanding of visitors’ perceptions relating to fire and fire management.

Kno.e.sis Publications

We developed a novel analytical environment to aid in the examination of the extensive amount of interconnected data available for genome projects. Our focus is to enable flexibility and abstraction from implementation details, while retaining the expressivity required for post-genomic research. To achieve this goal, we associated genomics data to ontologies and implemented a query formulation and execution environment with added visualization capabilities. We use ontology schemas to guide the user through the process of building complex queries in a flexible Web interface. Queries are serialized in SPARQL and sent to servers via Ajax. A component for visualization of the …

Proposed Route To Cyclopenta[C]Thiophenes Via Activated Methylene, Vineet V. Karambelkar

Masters Theses & Specialist Projects

The synthesis of cyclopenta[c]thiophenes has been sparsely reported in the literature owing to several difficulties involved in their synthesis. The present work involves the proposed synthesis of cyclopenta[c]thiophenes and their precursors using activated methylene. Cyclopenta[c]thiophene compounds show promise in the field of polymer and catalysis chemistry. These substituted polythiophenes are potential organic semiconductors and anti-tumor agents. The research presented shows the successful and novel conversion of 3,4-bis(chloromethyl)-2,5-dimethylthiophene and 3,4-bis(bromomethyl)-2,5-dimethylthiophene to a fused 5,5'-fused membered ring which is the precursor to cyclopenta[c]thiophene the sulfone ester, 5-carbomethoxy-5- phenylsulfonyl-1,3-dimethyl-5,6-dihydro-4H-cyclopenta[c]thiophene, in just two steps as compared to four steps previously reported in the literature. …

A Selectivity Study On The Use Of Caffeine And Theobromine Imprinted Polypyrrole Surface Electrodes, Anil Kiran Kumar Vinjamuri

Masters Theses & Specialist Projects

Molecularly imprinted polymers (MIPs) are proving to be very effective in development of synthetic recognition systems and are of great interest to those interested in the field of sensor technology. The use of MIPs is receiving considerable interest due to the ability to prepare recognition matrices that possess high substrate selectivity and specificity. Conducting polymers (CP) have proved to be an excellent tool for the preparation of nano-structured biologically selective systems. Polypyrrole (Ppy) is one such CP that is extensively used for the construction of bioanalytical sensors. Ppy has shown great promise primarily due to its biocompatibility and thermal stability …

Admicelle-Based Solid Phase Extraction Of Phenols Using Dialkylammonium Surfactant In The Hydroxide Form, Kali R. Pickering

Masters Theses & Specialist Projects

A technique for admicelle-based solid phase extraction is presented in which a dialkylammonium surfactant in the hydroxide form is immobilized on silica. By converting dihexadecyldimethylammonium bromide to the hydroxide form, the surfactant is allowed to have the property of a strong base, aiding in the extraction of acidic phenols which are difficult to extract because of their differing polarities. The surfactant-silica admicelle parameters were optimized for the efficient extraction of eight phenols. Adsorbed phenols were eluted from the sorbent using small volumes of methanol. The phenols were preconcentrated from drinking water samples and were determined using high performance liquid chromatography …

Geology And Hydrology Of Karst In West-Central And North-Central Florida, Lee J. Florea

Earth, Environmental, and Atmospheric Sciences Faculty Publications

The state of Florida is blessed with the highest density of large springs in North America and hundreds of smaller springs where the water from limestone aquifers returns to the surface (Scott et al., 2004). Spectacular underwater caves supply water to these springs. Lesser known are the equally fantastic air-filled caves of Florida and South Georgia (Florea, 2006; Lane, 1986). This paper features these underwater and airfilled caves, explores the impact of changes in sea level on karst in this near-coastal environment, and establishes several geologic and hydrologic characteristics that distinguish karst in the limestones of the southeast from karst …
