Tracer Tests In Karst Hydrogeology And Speleology, Nico Goldscheider, Joe Meiman, Michiel Pronk, Christopher Smart

International Journal of Speleology

This article presents an introduction to the fundamentals of tracing techniques and their application in cave and karst environments, illustrated by case studies from the Mammoth Cave, USA, and a small experimental site in Switzerland. The properties and limitations of the most important artificial tracers are discussed, and the available methods of tracer injection, sampling, online monitoring and laboratory analysis are presented. Fully quantitative tracer experiments result in continuous or discrete concentration-time data series, i.e. breakthrough curves, and concomitant discharge data, which make it possible to obtain detailed information about groundwater flow and contaminant transport. Within the frame of speleological …

A Review Of Assistive Technology And Writing Skills For Students With Physical And Educational Disabilities, Howard P. Parette, Jack J. Hourcade, George R. Peterson-Karlan

Faculty Publications - College of Education

In recent years effective instruction in reading for learners with physical
and educational disabilities has received great attention in the schools.
However, instruction in the corollary skill of writing has received considerably less emphasis. This review paper notes that through the use of assistive technology, students with a variety of physical and educational
disabilities can learn to effectively (a) plan and organize their writing,
(b) draft and transcribe their work, and (c) edit and revise their narrative
and expository writing.
With teachers increasingly being held accountable for the development of
literacy skills in all students, including those students with physical …

Age is a value-laden cultural construct as it conveys social attitudes toward aging. This qualitative research, using a grounded theory approach and critical feminist gerontology as a theoretical framework, makes visible the experience of growing older and the renegotiation of self-identity among the ten single, professional, highly educated women ages 47-59 who resided in the Pacific Northwest and lets their voices be heard. In this study ten in-depth interviews and one focus group provided narrative data that captured women’s experiences of aging and uncovered common themes. The explored phenomenon of aging is experienced in the various socio-cultural contexts and conditions …

The Prevalence Of Delinquency In Depressed And Substance Abusing Adolescent Girls, Susan C. Hunt

Antioch University Dissertations & Theses

Research conducted on the role of depression in delinquency among adolescent girls has found that depression can predict delinquency. It has been indicated that research should be conducted on how substance use and abuse play a role in depression and delinquency. Several studies have been conducted on adolescent girls in juvenile delinquent centres and institutions. Few studies have sampled subjects from community-based resources, i.e., street youth clinics, youth programs, or alternative schools. The central goal of the study was to explore delinquency in a group of depressed and substance-abusing adolescent girls in community-based settings including street clinics, youth programs, and …

Life-Affirming Leadership: An Inquiry Into The Culture Of Social Justice, Raquel Delores Gutierrez

Antioch University Dissertations & Theses

A new paradigm for leading social change is emerging; a worldview acknowledging the importance of leadership that is life-affirming and lasts over time. The current inquiry explored the ways in which the social reality of Life-Affirming Leadership is created and the implications those realities have for the current and future generations of social justice workers, their organizations, and the communities in which they work. The dominant paradigm for social justice work needs to be radically renovated (see Horwitz, 2002; James, 2005; Ohlson, 2006; Polansky, 2005; Utne, 2006; Wheatley, 2005; Williamson, 1997; Yáhzí, 2005); as such, a re-evolution is in progress, …

The Leadership Self-Identity Of Women College Presidents, Robbie Hertneky Phd

Antioch University Dissertations & Theses

The purpose of this research study was to explore the concept of leadership self-identity in a particular population of formal leaders—women college presidents. Using narrative inquiry, the research examined the following: how these women describe and define themselves as leaders, what personal attributes they believe allow them to be leaders, their past and future career intentions, how their relationships with others influence their leadership self-identity, and the stories they tell about themselves and leadership. Participants were asked questions designed to reflect their core identity and personal narrative, and to describe their career and relationships. Common themes that emerge include: how …

Small School Leadership: A Q Method Study Of Elements Of Leadership Specific To A Small School Setting, Charis Eirene Sharp

Antioch University Dissertations & Theses

Smaller schools have become an extremely popular school reform model. Research that connects them to student achievement is being used to support and create autonomous small schools as well as schools-within-schools. While it would seem to be a logical application, the schools-within-schools model is not performing at the levels expected as indicated by the small schools research. Research on these two different school settings needs to be separated, examined, and applied independently. Areas lacking research include questions about which aspects of schools support the functioning of the school, such as leadership. This study used Q-methodology to study leadership in a …

Theses

Nowadays, the cancer topic has become a global concern. Furthermore, breast cancer persists to be the top leading cause of death to women population and the second cause of cancer death after the lung cancer globally. Various technologies and techniques have been searched, developed and studied over the years to detect the disease at the early stage; the early diagnosis saves many lives in both developed and developing countries. The detection of cancer through a screening process before its symptoms emerge increases the survival rate dramatically (Li, Meaney and Paulsen). Moreover, sufficient knowledge of the disease, qualified staff, accurate, appropriate …

Counting Points On Elliptic Curves Over Zp, Suresh Sundriyal

Theses

The mathematics of elliptic curves has been studied since ancient times. These mathematical structures have found applications in varied fields. More recently, there has been a growing interest in applying these structures to cryptography. Various such applications have been proposed. Elliptic curve based cryptographic algorithms have been shown to provide greater security with shorter key sizes than the conventional RSA based cryptosystems, making them more memory e cient and less processor intensive. One of the fundamental requirements of all such elliptic curve cryptographic algorithms is that the order of the group of points satisfying the elliptic curve meet a certain …

Elliptic Curve Cryptography: Generation And Validation Of Domain Parameters In Binary Galois Fields, Peter Wozny

Theses

Elliptic curve cryptography (ECC) is an increasingly popular method for securing many forms of data and communication via public key encryption. The algorithm utilizes key parameters, referred to as the domain parameters. These parameters must adhere to specific characteristics in order to be valid for use in the algorithm. The American National Standards Institute (ANSI), in ANSI X9.62, provides the process for generating and validating these parameters. The National Institute of Standards and Technology (NIST) has identified fifteen sets of parameters; five for prime fields, five for binary fields, and five for Koblitz curves. The parameter generation and validation processes …

This thesis is concerned with the Reverse Engineering of Mesa code. Mesa is a programming language used by the Xerox Corporation especially designed for ultra large scale software projects. Many Xerox projects have considerable amounts of code already developed and in service with very little up to date design documentation. The maintenance phase of Software requires that updates will occur continuously in response to customer demands. Software engineers, often not the original designers, will need to gain a thorough understanding of the code to make reliable changes. This thesis proposes to outline Software tools developed in Mesa that will extract …

Toward The Construction Of "Kentucky Food" In The Twenty-First Century: Food Localism And Commodification Of Place Identity Under Post-Tobacco Agricultural Restructuring, 1990-2006., Taro Futamura

University of Kentucky Doctoral Dissertations

This study examines the concept of local food and the discourses surrounding the concept, both of which have played a significant role during Kentuckys agricultural restructuring. Since the mid-1990s, Kentucky farmers who were dependent on tobacco production began to struggle financially after the substantial reduction of quota allotments, and they were encouraged to diversify their agricultural production. Subsequently, practices of producing, marketing, and consuming locally-grown food were implemented. Drawing primarily on qualitative data, this study investigates the meanings of Kentuckys local food discourse development in four dimensions: 1) the political economy of tobacco production and the structural change of Kentuckys …

Cultivating Change: New Products From Costa Ricas Countryside, Erin Michelle Ricci

University of Kentucky Doctoral Dissertations

This dissertation examines rural families responses to global and local situations that have made earning a livelihood as a farmer very difficult. Drawing from original research, including a household livelihood census of 195 households, interviews with 72 people, participant observation, and archival research, the dissertation explores how rural families have responded to declines in domestic agricultural markets fueled by global and national forces and local environmental change. It asks: what impact will small farming families responses to these forces of change have on peoples identities as peasants? I argue that while great change is underway in the countryside, peasant identity …

The Inheritance Of Cold Tolerance In A Seeded Bermudagrass (Cynodon Dactylon L. Pers.) Population, Thomas Richard Stefaniak

University of Kentucky Doctoral Dissertations

One of the principle factors that limits the areas to which seeded bermudagrass can be adapted is low temperature. Therefore, increasing the winter tolerance of seeded bermudagrass cultivars has been a goal of turfgrass breeders for many years. Design of an efficient breeding method for developing cultivars with increased tolerance to cool and freezing temperatures could be enhanced by having heritability estimates for cold tolerance traits. Additionally, the identification of correlated traits can be useful in improvement of cultivar development. Heritability estimates for winter tolerance can be obtained from cold treatments imposed artificially or from observations made in the field. …

Loline Alkaloid Biosynthesis Gene Expression In Epichloe Endophytes Of Grasses, Dong-Xiu Zhang

University of Kentucky Doctoral Dissertations

Loline alkaloids (LA) are secondary metabolites produced by Epichloandamp;euml; (anamorph, Neotyphodium) grass endophytes. They are toxic and deterrent to a broad range of herbivorous insects but not to livestock. This protective bioactivity has spurred considerable research into the LA biosynthetic pathway. LOL, the gene cluster containing nine genes, is required for LA biosynthesis. The regulation of LOL genes during LA production in culture and in symbio is of interest. In this study, coordinate regulation between LOL gene expression and LA production level was investigated in both MM culture and symbiota. Results showed that expression of LOL genes in N. uncinatum …

Production Of Low-Energy, 100% By-Product Cement Utilizing Coal Combustion Products, David E. Rust

University of Kentucky Master's Theses

The ever-increasing quantity of by-products generated from burning coal in the production of electricity has brought about the need for new areas of utilization. This study examined the use of FGD gypsum and fluidized bed combustion ash along with Class F fly ash in the production of low-energy, 100% by-product cement blends. The cement blends used the advantageous properties of the by-product materials to create cementing properties rather than energy intensive clinker used in ordinary portland cement. The FGD gypsum was converted to hemihydrate which rapidly hydrated to provide the cement with early strength gains, whilst the fluidized bed combustion …

Effects Of Fescue Herbicides Plateau® And Cimarron® On Pregnancy Maintenance In Broodmares And On Alkaloid Concentrations In Endophyte Infected Tall Fescue, Kathleen Scarlett Black

University of Kentucky Master's Theses

Ingestion of endophyte infected (E+) fescue by pregnant mares can cause significant reproductive problems. Plateau® and Cimarron® herbicides suppress fescue while leaving desired forages unharmed. To determine if these herbicides are harmful to pregnant mares, they were allowed to graze pastures treated with Plateau®, Cimarron®, or vehicle carrier. Pregnancies were monitored via ultrasonography, blood chemistry, and hematology. Of the components measured only creatinine differed among treatments over time (P=0.0003) and that increase was only significant in one of four studies.

Two additional experiments were conducted to determine the effect of the herbicides on alkaloids within E+ fescue. A greenhouse experiment …

Being A Man In Kentucky: Perspectives Of Rural Migrant Workers, Mitchell Beam Snider

University of Kentucky Master's Theses

This thesis concerns identity constructions among rural migrant workers in Kentucky in relation to experiences and articulations of transnational spaces, networks, and identities. It was conducted through semi-structured interviews of migrant laborers on two rural Kentucky horse farms with 13 men. In this project, the men’s identities could be seen to have access to and utilize social, economic, cultural, and familial connections across national borders. These aspects of transnational identities were contrasted and compared to aspects of these men’s masculine identities to problematize popular representations of masculinities. This thesis shows how traditional notions of masculinities are questioned, reinforced, discarded, touted …

Targeting The Metal Chelator D-Penicillamine To Exploit The Elevated Copper And Oxidative Stress Associated With Cancer, Anshul Gupte

University of Kentucky Doctoral Dissertations

The significantly increased copper and oxidative stress levels are characteristic hallmarks of cancer cells. These differences provide a unique opportunity for selective targeting of cancer cells. D-penicillamine (D-pen) has been proposed to generate reactive oxygen species (ROS) in presence of copper. Therefore, these studies were aimed at investigating the potential application of a currently marketed copper chelator, D-pen, as a novel cytotoxic anti-cancer agent. D-pen was shown to produce ROS, specifically hydrogen peroxide (H2O2), in the presence of cupric sulfate through a copper catalyzed oxidation reaction. During this process D-pen was converted to D-pen disulfide. The experimental proof of the …

Academic and governmental analyses of HOPE VI have used economic, political, and social perspectives to analyze this significant financial investment, radical landscape alteration, and change in residents lives. This dissertation analyzes the process of HOPE VI and its attendant landscapes using a critical humanist …

Innovative Techniques For Digitizing And Restoring Deteriorated Historical Documents, George V. Landon, Jr.

University of Kentucky Doctoral Dissertations

Recent large-scale document digitization initiatives have created new modes of access to modern library collections with the development of new hardware and software technologies. Most commonly, these digitization projects focus on accurately scanning bound texts, some reaching an efficiency of more than one million volumes per year. While vast digital collections are changing the way users access texts, current scanning paradigms can not handle many non-standard materials. Documentation forms such as manuscripts, scrolls, codices, deteriorated film, epigraphy, and rock art all hold a wealth of human knowledge in physical forms not accessible by standard book scanning technologies. This great omission …
