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 …

Population Variability Of Rotylenchulus Reniformis In Cotton Agroecosystems, Megan Leach

All Dissertations

Rotylenchulus reniformis, reniform nematode, is a highly variable species and an economically important pest in many cotton fields across the southeast. Rotation to resistant or poor host crops is a prescribed method for management of reniform nematode. An increase in the incidence and prevalence of the nematode in the United States has been reported over the last two decades. However it is not clear whether the observed increase is related to the emergence of novel populations that are more aggressive or have a higher fitness or shifts in host availability or susceptibility. The objectives of this research were to determine …

Novel Vascular Grafts Based On Polyphenol-Stabilized Acellular Tissue Scaffolds, Ting-Hsien Chuang

All Dissertations

The Cardiovascular diseases (CVDs) continue to be the leading cause of morbidity and mortality worldwide. The most common form of CVDs is occlusion of blood flow thus limiting blood supply to specific tissues or organs. Atherosclerosis is a leading cause of coronary heart disease and stroke, which were responsible for more than 25% of deaths in 2004.
The demand for vascular graft is huge. In United States alone, approximately 500,000 coronary artery bypass graft surgeries are performed annually. Synthetic polymers such as Dacron and ePTFE have been successfully applied in large diameter blood vessel prosthesis; however, for small diameter (inner …

Evaluation Of Factors That Modulate Cellular Adipogenesis For Breast Tissue Engineering Strategies, Cheryl Gomillion

All Dissertations

It is estimated that this year more than 200,000 women in the United States will be diagnosed with breast cancer. Treatment for most occurrences of breast cancer will often include surgical removal of the tumorigenic tissue, resulting in a soft tissue defect within the subcutaneous tissue of the skin. Post-surgical reconstruction methods are often sought by patients to restore the aesthetic function of the breast via cellular or non-cellular methods; however, because of complications associated with currently used methods for breast reconstruction, researchers are investigating tissue engineering methods to produce viable autologous adipose tissue for breast reconstruction.
Previous research in …

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 …

Sequencing And Functional Analysis Of A Multi-Component Dioxygenase From Pah-Degrading Sphingomonas Paucimobilis Epa505, Renuka Miller

All Dissertations

Polycyclic aromatic hydrocarbons (PAHs) are hydrophobic organic compounds consisting of two or more fused benzene rings. PAHs derive from many different sources including petroleum refining, wood treatment, and coal coking industries. Because of their structural stability and water insolubility, PAHs are extremely resistant to degradation. These compounds are also believed to have mutagenic, carcinogenic, and teratogenic effects. Therefore, there are currently 16 PAH compounds on the EPA's list of priority pollutants.
Many species of bacteria have the ability to breakdown these persistent pollutants. However, bioremediation strategies using these organisms have many unresolved issues. While laboratory experiments can easily demonstrate the …

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 …

It notes that laws on abortion vary across different jurisdictions, like prohibiting abortion under all circumstances to freely allowing it without restriction as to reason.

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 …

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 …

Population Characteristics Of Central Stonerollers In Iowa Streams, Scott M. Bisping, Jesse R. Fischer, Michael C. Quist, Andrew J. Schaefer

The Prairie Naturalist

The central stoneroller (Campostoma anomalum) is a herbivore that can have substantial effects on algal communities, nutrient dynamics, and energy flow in streams. Despite its importance in lotic ecosystems, little is known about its population dynamics in streams of the Great Plains. Our objective was to describe age structure, age-specific mortality, and growth rates of central stonerollers in three Iowa streams. We sampled fish from 41 reaches during June-August 2007. We sampled 466 central stonerollers, of which we aged 192. Fish varied in length from 32 to 130 mm and in age from age 0 to 4 years. …

The Effect Of Explicitly Differentiated Reading Instruction Groups On Eighth-Grade Students' Achievement, Behavior, And Engagement In A School Seeking To Reestablish Adequate Yearly Progress Benchmarks, Sean P. Dunphy

Student Work

The purpose of this study was to determine the effect of explicitly differentiated reading instruction groups on eighth-grade students’ achievement, behavior, and engagement in a school seeking to reestablish adequate yearly progress benchmarks. The results of this study supported student participation in explicitly differentiated reading instruction groups. Because students in High Reading Ability (n = 25), Middle Reading Ability (n = 25), and Low Reading Ability (n = 25) groups maintained average to above average achievement test scores on several measures with commensurate classroom grade performance, and appropriate behavior and engagement to support school success during eighth grade, the results …

The Effect Of The Involvement Within Career Academies By Elective Participation Of Eleventh And Twelfth Grade High School Students During The Implementation Year, Nancy A. Johnston

Student Work

The purpose of this study was to determine the effect of elective participation in one of three implementation year Career Academies, Education, Entrepreneurship, or Finance, on upper-class high school academic grades, Grade Point Average, and school academy participation measures. Significance of the junior and senior year of high school, the meaning of a high school diploma and graduation requirements, and the connection to preparation for postsecondary studies and the world of work, career readiness, have become a focus of high school improvement efforts throughout the country. The implementation of the Millard Public Schools Career Academies in August of 2009 was …

Near Miss Reporting: An Educational Program, William Strub

Nursing Masters

In October 2007, the Medicare system contemplated future introduction of a new policy, which would no longer pay for eight preventable medical errors. With this potential new change in policy it becomes increasingly more important for health care institutions to monitor (track) medical errors and determine what measures can be taken proactively to prevent the occurrence of errors. The errors that might not be financially reimbursed under Medicare in the future include: - Sponges and/or surgical tools left in patients after surgery - Treatment of problems arising from air embolisms or incompatible blood transfusions - Treatment of bedsores developed while …

A Comparison Of Muscle Activity Responses Of Adults And Children During Whole Body Vibration, Dustin Blair Nash

Undergraduate Honors Capstone Projects

Results of recent studies have suggested that attenuation and transmissibility of WBV in adults and children are similar, but due to anatomical differences, it is hypothesized that children employ different strategies. One suggested strategy is that of muscle tuning, whereby muscle activity levels are adjusted to control potentially dangerous accelerations produced by vibration resonance. The purpose of the study was to compare muscle activity responses between children and adults exposed to whole body vibration. It was hypothesized that the muscle activity in children would be greater than that in adults due to muscle tuning strategies. Eleven adults and fourteen children …

The Epidemiology Of Bacterial Vaginosis In Relation To Sexual Behaviour, Hans Verstraelen, Rita Verhelst, Mario Vaneechoutte, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

Background: Bacterial vaginosis (BV) has been most consistently linked to sexual behaviour, and the epidemiological profile of BV mirrors that of established sexually transmitted infections (STIs). It remains a matter of debate however whether BV pathogenesis does actually involve sexual transmission of pathogenic microorganisms from men to women. We therefore made a critical appraisal of the literature on BV in relation to sexual behaviour.

Discussion: G. vaginalis carriage and BV occurs rarely with children, but has been observed among adolescent, even sexually non-experienced girls, contradicting that sexual transmission is a necessary prerequisite to disease acquisition. G. vaginalis carriage is enhanced …

In Service Of Mission: Assessing Catholic School Guidance Counselors, Robert J. Murray, Kristy S. Kane

Journal of Catholic Education

Catholic schools are set apart from public schools in that Catholic schools aim to create for the school community an atmosphere enlivened by the Gospel spirit of freedom and charity. Those who serve in Catholic schools, therefore, need to understand their role as unique, that is, faith driven. The purpose of this study was to assess this uniqueness as understood and practiced by Catholic school counselors. The findings of this study note positive trends among Catholic school counselors, particularly in terms of academic preparation and training as well as some incorporation of Catholic identity and mission into their ministry with …

Catholicism on Campus: Stability and Change in Catholic Student Faith by College Type

Introduction To The Special Issue: Homelessness In Canada, John R. Graham, Jeannette Waegemakers Schiff

The Journal of Sociology & Social Welfare

In February 2009, over 700 people gathered for more than three-days at 'Growing Home,' Canada's second national conference on housing and homelessness (www.nhc2009. ca) to explore causes and solutions to this urgent problem. Conference delegates included those who are experiencing or have experienced homelessness, their families, policy analysts, political activists, politicians, professionals, scholars, those in the affordable housing community, and concerned citizens generally. Over 140 academic papers and workshops were delivered by the country's leading researchers and homelessness- serving practitioners.

Perspectives Of Employed People Experiencing Homelessness Of Self And Being Homeless: Challenging Socially Constructed Perceptions And Stereotypes, Micheal L. Shier, Marion E. Jones, John R. Graham

The Journal of Sociology & Social Welfare

In a study that sought to identify the multiple factors resulting in homelessness from the perspective of 65 individuals in Calgary, Alberta, Canada who were both employed and homeless, we found that participants' perceptions of being homeless emerged as a major theme which impacts their entry to and exit from homelessness. Four sub-themes related to these perceptions were identified: (1) perceptions of self and situation; (2) impact of being homeless on self-reflection; (3) aspects of hope to consider; and (4) perspectives on having a permanent residence. Analytically, these findings help challenge present stereotypes about homelessness and usefully inform social service …

The Limits Of Social Capital: An Examination Of Immigrants' Housing Challenges In Calgary, Alina Tanasescu, Alan Smart

The Journal of Sociology & Social Welfare

A common explanation of immigrants' under-representation among the homeless population in Canada is that kinship and community networks act as a buffer to absolute homelessness. There are indications that immigrant homelessness is, however, increasing, suggesting that the buffering capacity of social networks reaches a limit. Further, evidence of precarious housing situations indicates that we should approach this form of housing provision with some caution. This paper draws on a larger study of housing difficulties among immigrants in Calgary to address the ways in which social capital serves a buffering role, and under what conditions it loses its ability to prevent …
