4-H Leaders: Factors That Affect Their Persistence In The 4-H Youth Development Program, Regina Schinker

Dissertations

For over one hundred years, the 4-H youth development program has educated millions of children across the country in a variety of programs; from livestock husbandry to leadership skills. Like all programs that have endured, 4-H has had to adjust its focus as society has changed. One area in the 4-H program that has not changed is the heavy reliance on adult volunteer leaders to deliver the educational programs to 4-H youth. Because of the reliance on volunteer 4-H leaders, 4-H professionals and extension office staff are concerned about issues of retention.

The case study examines two related issues: First, …

The Effects Of A Course On Statistical Literacy Upon Students' Challenges To Statistical Claims Made In The Media, Rose Martinez-Dawson

All Dissertations

Statistical literacy involves critically evaluating and questioning statistics encountered in everyday life. The purpose of this study was to evaluate students' questions (challenges) concerning statistics encountered in everyday life and how these challenges differed before and after taking an undergraduate statistics course, entitled Statistics in Everyday Life 200 (SIEL), which focused on statistical literacy. One hundred forty-four students were given three media articles to indicate questions they had concerning statistics cited in the articles and explain why these questions were important to ask. Students' responses were categorized based on the topic and were assessed using the Statistics Literacy Components Rubric …

Debugging Techniques For Locating Defects In Software Architectures, Kyungsoo Im

All Dissertations

The explicit design of the architecture for a software product is a well established part of development projects. As the software architecture descriptions are becoming larger and more complex, there is more likelihood of defects being present in the software architecture. Studies have shown that a defect in the software architecture that has propagated to the development phase is very expensive to fix. To prevent such propagation of defects, this research proposes to provide debugging support for software architecture design.
Debugging is commonly used in programming languages to effectively find the cause of a failure and locate the error to …

Identification And Characterization Of Micrornas In Porcine Gametes And Pre-Implantation Embryos, Erin Curry

All Dissertations

MicroRNAs (miRNAs) are short ribonucleic acids that ultimately affect the production of proteins. Although miRNAs are involved in nearly every biological process examined to date, little is known of the identity or function of miRNA in porcine reproductive tissues or their potential involvement in reproductive processes in pigs or other species. The objective of this dissertation research was to determine the presence of miRNAs in porcine gametes and both in vivo- and in vitro- produced pre-implantation embryos and to identify differences in miRNA expression between normal and aberrant samples. Using a heterologous RT-PCR approach, we demonstrated the presence of a …

Multilevel Antecedents Of Economic Stress, Mark Zajack

All Dissertations

Much of the literature on economic stress focuses on outcomes. This study assessed the antecedents that precede employee perceptions of economic strain. A multilevel framework of economic antecedents was proposed. The framework included objective indicators of the macroeconomic context as well as individual-level objective and subjective economic antecedents. It was hypothesized that antecedents within each of these categories of economic stress can fall into one of two dimensions: employment- or finance-related. Indicators of the macroeconomic context were gathered from the American Community Survey (ACS). Over 2,000 union employees of a large U.S. Midwestern retail chain provided individual employee-level economic information …

Deadly Discourse: Negotiating Bureaucratic Consensus For The Final Solution Through Organizational And Technical Communication, Mark Ward Sr

All Dissertations

The Final Solution was largely accomplished in eleven months; its executors, the Nazi SS, faced the constant problem that as killing and plunder escalated so did internal competition and corruption; and the SS deliberately cultivated an intensely competitive and polycratic organizational culture that fit the Nazi worldview of life-as-struggle. By tying these three observations together—that the Final Solution was punctuated, entropic, and polycratic—the problem arises: How did SS organizational communications manage, just barely long enough, to create a temporary social reality that regulated the internal contradictions of its genocidal project and fragmented bureaucracy? This study contends that through its organizational …

Approximation Algorithms For Network Interdiction And Fortification Problems, Adam Whitley

All Dissertations

This dissertation discusses algorithms and results on several NP–hard graph problems which can all be classified as network interdiction and network fortification problems.
The first problem studied, the multiway cut problem, is a generalization of the well–studied s–t min–cut problem, in which we must remove a minimum–cost subset of edges from a graph so that r > 2 designated terminals become disconnected from each other. We investigate an approximation algorithm for general r with a relatively simple analysis guaranteeing an approximation ratio ≤ 1.4647 − epsilon_r, where epsilon_r is a small constant related to the number of terminals …

Predictive Energy Management In Connected Vehicles: Utilizing Route Information Preview For Energy Saving, Chen Zhang

All Dissertations

This dissertation formulates algorithms that use preview information of road terrain and traffic flow for reducing energy use and emissions of modern vehicles with conventional or hybrid powertrains. Energy crisis, long term energy deficit, and more restrictive environmental protection policies require developing more efficient and cleaner vehicle powertrain systems. An alternative to making advanced technology engines or electrifying the vehicle powertrain is utilizing ambient terrain and traffic information in the energy management of vehicles, a topic which has not been emphasized in the past. Today's advances in vehicular telematics and advances in GIS (Geographic Information System), GPS (Global Positioning Systems), …

Modeling The Galactic 511 Kev Positron Annihilation Emission, Production, And Propagation, Bethany Johns

All Dissertations

The Galactic 511 keV positron annihilation emission has a strong bulge component to the emission and a weak disk component. The bulge emission is about 1.4 -- 6 times as the disk emission. The bulge emission is defined to be a diffuse emission centered at the Galactic center and extends to about a FWHM of 8 degrees in Galactic longitude and latitude. An asymmetry has also been observed in the disk emission, where the negative longitudes are brighter than the positive longitudes by a factor of 1.8.
This research examines the morphology of the Galactic 511 keV positron annihilation emission …

A Study Of African American Forest Landowners In South Carolina: Implications For Land Ethic And Forest Stewardship, Keenan Adams

All Dissertations

African Americans account for a significant proportion of South Carolina`s
population but reportedly own a disproportionally smaller amount of land. Research indicates that landowners who hold significant sources of sustainable wealth and power can dramatically increase their quality of life and ultimately that of their communities. Current land loss trends for African Americans are increasing at an alarming rate, which may have larger social implications for this traditionally underserved population. The remaining African American landowners are a rapidly declining group, due to an assortment of factors (e.g., age, heirs property). Understanding the experiences of the residual African American forest landowners …

A Structural Equation Model Of Leader Attributes In The Principalship, Amy Young

All Dissertations

To become a principal in South Carolina, one must have teaching experience, a master's degree, and certification in the area of primary responsibility. Beyond what is learned through coursework, internships, and certification tests, what intangible factors critically influence a principal's actions and decisions, and (ultimately) success? Trait theory begs the question of whether any of these criteria truly influences the decisions and actions of the principalship. Are there interactive traits of leadership that describe the behaviors of school principals? This study revisits trait theory by examining leader attributes relative to the principalship of South Carolina public schools. This study replicates, …

The Impact Of University Housing Construction Type On Psychosocial Development Of First-Year Students, Justin Owens

Development And Characterization Of Novel Sub-Coatings With Polymorphic Brookite Titania Nanoparticles: Enhanced Uv/Vis Photocatalytic Antibacterial And Anticancer Properties, Donna Weinbrenner

All Dissertations

ABSTRACT
Nosocomial and community infections and biofilm formation from bacteria has increased significantly through adaptation combined with overuse of broad spectrum antibiotics. Because the world population continues to escalate, hospitals and long-term managed care will also escalate, thereby increasing transmission of infections, lowering patients' quality of health. Another disease on the rise throughout the world is skin cancer. A treatment modality that would cause less deleterious effects on the patient would be ideal. These two seemingly different issues could be solved with one product. First an inexpensive, safe, and non-selective antimicrobial surface coating would enhance the hospital arena and a …

Monetary And Fiscal Policy Interactions In Nigeria: An Application Of A State-Space Model With Markov-Switching, Chuku V. Chuku

CBN Journal of Applied Statistics (JAS)

This paper uses quarterly data to explore the monetary and fiscal policy interactions in Nigeria between 1970 and 2008. As a preliminary exercise, the paper examines the nature of fiscal policies in Nigeria using a vector autoregression (VAR) model. The simulated generalized impulse response graphs generated from the VAR estimation provides evidence of a non-Ricardian fiscal policy in Nigeria. Further, the paper analyzes the interactions between monetary and fiscal policies by applying a State-space model with Markov-switching to estimate the time-varying parameters of the relationship. The evidence indicates that monetary and fiscal policies in Nigeria have interacted in a counteractive …

A Distributional Analysis Of Out-Of-Pocket Healthcare Financing In Nigeria Using A New Decomposable Gini Index, Ichoku Eme Hyacinth, William M. Fonta, Abdelkrim Araar

CBN Journal of Applied Statistics (JAS)

This study applies a new method of decomposing total redistributive effect of taxation proposed by Duclos et al. (2003) to assess the redistributive effects of direct healthcare financing in Nigeria. This new framework makes it possible not only to introduce into the conventional Gini Index estimation framework a flexible ethical measure of aversion to inequality but also a novel concepts of horizontal inequity and re-ranking. The empirical results indicate that when the decision to utilize healthcare is always linked to the decision to pay for healthcare, as is the case in Nigeria, out-of-pocket payment, contrary to existing literature, may indeed …

Factors, Preventions And Correction Methods For Non-Response In Sample Surveys, Godwin Nwanzu Amahi

CBN Journal of Applied Statistics (JAS)

Missing survey data occur because of unit and item non-response. This is practically independent of the method of data collection. As a result of the bias that non-response sometimes introduces in survey estimates, identifying factors that promote it, and taking measures of prevention and correction methods are clearly necessary. The standard method to compensate for unit non-response is by weighting adjustment, while item non-responses are handled by some form of imputation. This paper reviews factors that give rise to nonresponse and the corresponding methods used for its prevention and control. It also discusses their properties.

Addressing The Problem Of Non-Response And Response Bias, Fabian C. Okafor

CBN Journal of Applied Statistics (JAS)

Survey planners and analysts in Nigeria have devoted much more attention to sampling errors at the expense of nonsampling errors (non-response and response errors). Sampling error is the degree to which the sample estimate differs from the average value of the characteristic due to chance. The present discussion will be centered on non-sampling error, which may present serious deficiencies in the statistics and render the survey useless. According to Platek and Gray (1986), “Non-response has been generally recognized as important measure of the quality of data since it affects the estimates by introducing a possible bias in the estimates and …

Statistics For National Development, Sani I. Doguwa

CBN Journal of Applied Statistics (JAS)

Good statistics that has been collected according to agreed good practices are crucial as a tool for development. Gross domestic product (GDP) and other measures of economic activity such as Gross National Income (GNI) together with their individual components, show how the economy is responding to government policy and other influences. The balance of payments can demonstrate the requirement for policy adjustments and is also one of the indicators scrutinised by potential foreign investors in the country. Agricultural statistics clearly have implications for longer-term planning, particularly if they show a move away from the land into urban areas or a …

Lawmakers As Lawbreakers, Ittai Bar-Siman-Tov

William & Mary Law Review

How would Congress act in a world without judicial review? Can
lawmakers be trusted to police themselves? This Article examines
Congress’s capacity and incentives to enforce upon itself “the law of
congressional lawmaking”—a largely overlooked body of law that is
completely insulated from judicial enforcement. The Article explores
the political safeguards that may motivate lawmakers to engage in
self-policing and rule-following behavior. It identifies the major
political safeguards that can be garnered from the relevant legal,
political science, political economy, and social psychology scholarship,
and evaluates each safeguard by drawing on a combination of
theoretical, empirical, and descriptive studies about …

The Wrong Tool For The Job: The Ip Problem With Noncompetition Agreements, Viva R. Moffat

William & Mary Law Review

This Article argues that employee noncompetition agreements ought to be unenforceable. It begins by recognizing that there is momentum for change in the law of noncompetes: a number of states and the American Law Institute (ALI) are in the process of reconsidering noncompete doctrine, and recent empirical studies provide evidence as to the mostly negative effects of the agreements. Existing critiques have focused on the problematic nature of noncompetes within the employment relationship. This Article synthesizes those critiques, adding support from empirical studies, and then examines noncompetes from a new perspective.

Commentators have neither recognized nor evaluated the role noncompetes …

Why Are There Tax Havens?, Adam H. Rosenzweig

William & Mary Law Review

Recently, the issue of tax havens has risen to the fore of the fiscal policy debate, with tax havens being singled out as the root cause of many of the fiscal shortfalls plaguing the governments of the world. Surprisingly, however, although there has been a fair amount of literature on why tax havens are harmful to the modern international tax regime, which countries become tax havens, and what means are available to combat tax havens, there has been less written specifically on the underlying question of why, notwithstanding all these points, tax havens exist in the first place, or why …

Rejecting Refugees: Homeland Security's Administration Of The One-Year Bar To Asylum, Philip G. Schrag, Andrew I. Schoenholtz, Jaya Ramji-Nogales, James P. Dombach

William & Mary Law Review

Since 1980, the Refugee Act has offered asylum to people who flee to the United States to escape persecution in their homeland. In 1996, however, Congress amended the law to bar asylum—regardless of the merits of the underlying claim—for any applicant who fails to apply within one year of entering the United States, unless the applicant qualifies for one of two exceptions to the rule.

In the years since the bar was established, anecdotal reports have suggested that genuine refugees, with strong claims to asylum, have been rejected solely because of the deadline. Many scholars and practitioners suspected that this …

性別差異在醫學生與醫師人數以及專科別選擇之10年趨勢探討, 韋君 陳, 大成 璩, 潤秋 陳, 聖原 張

Journal of Medical Education

Physician manpower is considered to be an important index when evaluating medical service quality. Furthermore, gender has become an important topic recently. Variations in the gender profile of physicians may influence outcomes in terms of medical services. As a result, concern has focused lately on differences in the distributions of male and female physicians across specialties. We collected data from the Department of Education, Taiwan, and the National Health Insurance Database, Taiwan, in order to examine the male/female distribution of first year medical students, graduated medical students and new physicians over the years 1998 to 2007. Furthermore, we evaluated the …

The Chicago Experiment: Finding The Voice And Charting The Course Of Religious Education In The Church, Casey P. Griffiths

BYU Studies

In many professions, Latter-day Saints often struggle to find harmony between their religion and their career. This has been especially true in academia, in most of its diverse disciplines. These challenges were particularly fierce when the Church began developing its own corps of professional religious educators to teach and lead in the newly founded seminary and institute programs of the early twentieth century. In the early 1930s, religious educators in the Church developed a close relationship with the School of Divinity at the University of Chicago. Eleven young Latter-day Saint scholars earned advanced degrees at the school at the Church's …

A Question On My Mind: Robert Mccorkle's 1844 Letter To Joseph Smith, Hal R. Boyd, Susan E. Black

BYU Studies

Robert McCorkle (1807–1873) was one of many Americans curious about Mormonism. In 1844 he visited Nauvoo, Illinois, then headquarters of the Latter-day Saints. He hoped to obtain an audience with Joseph Smith but was able only to hear Smith speak at public meetings. When he returned to his home in Tennessee, he wrote to Smith, asking questions and describing his willingness to relocate to Nauvoo if Smith could prove that he was a true prophet. Interestingly, McCorkle wrote much of his letter in rhymed verse and hoped that Joseph Smith would reply in verse. It does not appear that Smith …

St. Louis Luminary: The Latter-Day Saint Experience At The Mississippi River, 1854–1855, Susan E. Black

BYU Studies

The St. Louis Luminary, a Latter-day Saint newspaper printed in St. Louis, was printed for only one year but chronicles the status of the LDS Church on the American frontier in 1854 and 1855. The 2010 book The Best of the St. Louis Luminary gives an in-depth history of the newspaper and its contents and includes a DVD of scans of the entire volume of the newspaper in a searchable format. This article is excerpted from that book. The newspaper played a significant role in the national discussion of polygamy, which had not been publicly announced until 1852. The …

Dating The Birth Of Christ, Jeffrey R. Chadwick

BYU Studies

The Church of Jesus Christ of Latter-day Saints has taken no official position on the exact date of Christ's birth. In his 1915 classic Jesus the Christ, Elder James E. Talmage maintained that Jesus Christ was born on April 6 in the year 1 BC. Talmage was apparently the first LDS writer to propose this particular date. Nearly a century has passed since his book appeared, and in that time it has become practically axiomatic among Latter-day Saints that Jesus was born on April 6 in that year. Two other Apostles, President J. Reuben Clark and Elder Bruce R. …

Examination Of Owl Pellets For Northern Pocket Gophers At Crescent Lake National Wildlife Refuge, Nebraska, Stacey L. Bonner, Keith Geluso

The Prairie Naturalist

Analysis of regurgitated pellets from owls is a well-known and nondestructive method that provides useful information regarding diet (Errington 1930). This technique also is used to examine composition of small mammal communities and distribution of prey species (e.g. Kamler et al. 2003, Torre et al. 2004, Poole and Matlack 2007). In western Nebraska, two species of owls that regularly breed in the region are the common barn owl (Tyto alba) and great horned owl (Bubo virginianus). In the early 1970s, Rickart (1972) studied the diet of both species at Crescent Lake National Wildlife Refuge (CLNWR), Garden …

Seasonal Yellow Perch Harvest In Two Dissimilar South Dakota Fisheries, Casey W. Schoenebeck, Michael L. Brown, David O. Lucchesi

The Prairie Naturalist

Angler effort and fish harvest in South Dakota have historically been quantified through summer and winter creel surveys. However, the late-summer, pulsed recruitment of yellow perch (Perea flavescens) into a fishery combined with an increase in fall movement and feeding activity suggested September and October could be significant periods of perch harvest in South Dakota lakes. Seasonal trends in angler effort and yellow perch harvest during 2005-2007 were compared for high- and low-quality yellow perch fishery types commonly found in eastern South Dakota glacial lakes. High-quality yellow perch fisheries are characterized by fast growth (mean total length at age-3 greater …
