An Exploration Of The Spatial Distribution Of National Park Units, Daniel Servian

Graduate Theses, Dissertations, and Problem Reports (ETD)

National Parks can reveal a glimpse into significant aspects of a culture. Visiting and experiencing a National Park can open a window into a culture's heritage, intellectual philosophy, triumphs, and sorrows. As of 2009, the National Park Service administered 393 National Park units, located across America and its territories. The purpose of this paper is to spatially investigate the National Park designation process. Examination of the trends and patterns within the National Park designation process required computation of the data via exploratory data analysis (EDA) and exploratory spatial data analysis (ESDA). This analysis will illustrate significant clusters and correlation between …

Effects Of Acid Mine Drainage And Acid Precipitation On Leaf Litter Breakdown Rates In Appalachian Headwater Streams, Mary Fiona Stewart

Graduate Theses, Dissertations, and Problem Reports (ETD)

Acid precipitation and acid mine drainage have dramatically altered chemical conditions and biological assemblages in streams throughout the central Appalachians. Effects of acidification on functional stream processes such as organic matter decomposition, however, remain poorly understood. The objectives of this study were to: (1) quantify differences in organic matter decomposition among reference streams, streams impacted by acid precipitation, and streams impacted by acid mine drainage; and (2) determine if lowered decomposition rates are the result of reduced microbial activity or altered invertebrate shredder assemblages or both. I quantified water chemistry, organic matter decomposition, microbial activity, and macroinvertebrate community structure in …

Hydrologic Soil Grouping Determination For Appalachian Minesoils, Anthony Willard

Graduate Theses, Dissertations, and Problem Reports (ETD)

The hydrologic soil group refers to the infiltration potential of the soil after prolonged wetting. This classification system separates soils into four hydrologic groups (A, B, C, and D), based upon the intake and transmission of water under conditions of maximum yearly wetness. Group A has the lowest runoff potential and D the highest. Several soil properties are used to determine the hydrologic soil groupings. In the study of the hydrologic soil nature, soil properties that affect infiltration, such as bulk density, porosity and texture, should be considered. Associated factors that affect infiltration in the field are slope and vegetation. …

Three Essays On Caps Market And Unspanned Volatility, Harumi Hattori

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this thesis we study the caps market. Caps are a contract where the interest rates are capped at some fixed value r¯. Caps consist of caplets which are European options on the forward rates called LIBOR (the London Inter-Bank Offer Rates). Caps are the derivatives of LIBOR. However, their relation is not so simple as the relation between a stock and its derivatives. One important difference is that the volatility in one market does not affect the volatility of the other market as much as in the stock and its derivative markets. This phenomenon is termed unspanned stochastic volatility …

Three Essays On The Foreign Exchange And Equity Returns, Alina F. Klein

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation contains three essays dealing with current issues in the foreign exchange and equity exchange markets. The first essay observes that both markets display behaviors akin to momentum and mean reversion. This essay implements a trading strategy combining mean reversion and momentum in foreign exchange markets. The strategy was originally designed for equity markets, but it also generates abnormal returns when applied to uncovered interest parity deviations for five countries. I find that the pattern for the positions thus created in the foreign exchange markets is qualitatively similar to that found in the equity markets. Quantitatively, this strategy performs …

Sub-Surface Stratigraphy And Petrophysical Analysis Of The Middle Devonian Interval Of The Central Appalachian Basin; West Virginia And Southwest Pennsylvania, Matthew Louis Boyce

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the central Appalachian basin, the Middle Devonian organic-rich shale interval, including the Marcellus Shale, is an important target for natural gas exploration. It has emerged as a giant unconventional resource play due to aerial extent and potential for individual wells to produce large volumes of gas. The Marcellus Shale is well studied on the surface without the incorporation of the subsurface stratigraphy. However, to fully understand the Marcellus economic potential it is important to investigate and map the related Middle Devonian sub-surface stratigraphic units. The interval studied includes the Onondaga Limestone (Eifelian), Marcellus Shale (Eifelian), Purcell Limestone (Eifelian), Mahantango …

Mandatory Reporting In The Context Of Home Visitation Programs, Danielle Marie Davidov

Graduate Theses, Dissertations, and Problem Reports (ETD)

Each year in the United States, 4.8 million physical assaults and rapes are committed against 1.5 million women by an intimate partner. An estimated 3.3 to 10 million children are exposed to some form of intimate partner violence (IPV) in their own homes annually. Although mandatory reporting laws regarding child abuse and/or neglect are implemented in all 50 U.S. states, the extent to which these laws are appropriate for IPV between adults and children exposed to IPV is undetermined. A comprehensive examination of the perspectives of those required to report abuse is critical, as their roles as mandated reporters often …

Understanding Plasmas Through Ion Velocity Distribution Function Measurements, Saikat Chakraborty Thakur

Graduate Theses, Dissertations, and Problem Reports (ETD)

This work concerns measurements of ion velocity distribution functions (IVDF) using three different diagnostic techniques in expanding argon plasmas generated by two different helicon plasma sources. A theoretical prediction by Lieberman et al., of enhanced upstream ionization by electrons accelerating upstream, due to the formation of a stable electrostatic current-free double layer (DL) in an expanding plasma, was verified through laser induced fluorescence (LIF) and retarding field energy analyzer (RFEA) measurements of the IVDF and Langmuir probe measurements of the plasma density. Keeping all other external source parameters constant and varying only the operating frequency of the helicon source HELIX, …

Spectral Approaches To Natural Mesh Processing, Takamitsu Kawai

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mesh design is a major bottleneck in the creation of computer games and animation. Therefore simplifying the process of mesh editing is an important problem. Natural mesh processing is generally difficult to perform since natural meshes often have nontrivial surface shapes and high degrees of freedom. In this study I present novel approaches to natural mesh processing utilizing spectral methods based on the manifold harmonic basis.;Geometric scaling transformations do not respect the biological processes which govern the size and shape of living creatures. I describe an approach to scaling which can be related to biological function. Known biological laws of …

Incarcerating Indigenous People Of The Wongatha Lands In The Eastern Goldfields Of Western Australia : Indigenous Leaders’ Perspectives, Stephen J. Bedells

Theses: Doctorates and Masters

The Wongi

people are Indigenous to the Goldfields region and account for just 10 per cent of the population; yet they make up 90 per cent of the prisoners. With Indigenous incarceration rates above 8,000 per 100,000 adult male population in Western Australia, imprisonment is clearly a common experience for Indigenous men and women that profoundly affect the lives of their families. Gaols are meant to be used as a sentence of last resort when the severity of the offence requires severe punishment and prevention of further offences requires close confinement. For this research, Wongi leaders were interviewed about their …

Selective Self-Stereotyping And Women’S Self-Esteem Maintenance, Debra L. Oswald, Kristine M. Chapleau

Psychology Faculty Research and Publications

The process and implications of gender-based self-stereotyping are examined in this paper. Women displayed a tendency to selectively self-stereotype for personality and physical traits such that they endorsed positive stereotypic traits and denied negative traits as descriptive of the self and closest women friends. However, negative traits were endorsed as descriptive of women in general. Cognitive stereotypes were endorsed as more descriptive of all women than of the general university student. The tendency to selectively self-stereotype on physical traits was positively associated with appearance, social, and performance self-esteem. The results are discussed for their theoretical and practical implications.

Normative Reflectance And Transmittance Measurements On Healthy Newborn And 1-Month-Old Infants, Gabrielle R. Merchant, Nicholas J. Horton, Susan E. Voss

Engineering: Faculty Publications

Objective:

Ear-canal-based wideband reflectance (WBR) measurements may provide objective measures to assess and monitor middle-ear status in young babies. This work presents WBR measurements of power reflectance and transmittance on populations of healthy newborn babies (3 to 5 days) and healthy 1-mo-old babies (28 to 34 days). Thus, this work determines how power reflectance and transmittance vary between newborn and 1-mo-old babies and characterizes the range of these measures in normal populations.

Design:

Power reflectance and transmittance were calculated from pressure measurements made in the ear canals of seven newborn (12 ears) and eleven 1-mo-old (19 ears) babies. Permutation tests, …

Examining The Effectiveness Of Dropout Prevention Practices And Their Implications For Intervention With Public School Students, Louisa Pollack

Dissertations

Schools face the dilemma of transforming both the trend of students dropping out of school and the associated negative socioeconomic outcomes into a positive path of persistence and school completion. Despite ongoing efforts of the federal and state government, as well as those of the local school districts, this problem continues to burden the educational system and society as a whole. The opinions of those with the experience of dropping out and returning to school are pertinent sources of information on educative practices that can help stem the dropout rate.

A survey was conducted to gather the opinions of students …

Administrators' And Teachers' Perceptions Of In-School Suspension, Amelia Shondra Jackson

Dissertations

Providing a safe and orderly school environment for students to learn is of paramount importance to school administrators, teachers, students, and the general public; however, the learning process should not be compromised while trying to maintain such an environment. There are many alternative approaches that can be utilized that would rectify the problem we as educators face in providing a safe and orderly environment. At-risk students are usually the ones who have the most serious infractions. These students exhibit a cyclical pattern of recalcitrant behavior. It is imperative that these at-risk students be identified as early as possible, and intervention …

Emotional Maturity Of Adolescents And Adults In Ged Programs, Billy Joe Riffle

Dissertations

When discussing issues relating to students in General Educational Development (GED) Option and pre-GED programs with educators, the contention exists that it is possible to make reasonably accurate predictions on the success or failure of a student by observing a number of items. Looking at their cumulative records shows their academic and attendance history. Insight is gained by looking at their family dynamics and how they relate to adults. Much can be learned about them from their discipline reports and the nature of any infractions. One of the most intriguing aspects gained through experience and observation is the perception of …

Life History And Habitat Use Of The Juvenile Alabama Shad (Alosa Alabamae) In Northern Gulf Of Mexico Rivers, Paul Fraser Mickle

Dissertations

The Alabama shad, Alosa alabamae, is an anadromous species that is in decline and has seen extirpations from impoundments as well as decreased water quality. Alabama shad live in the Gulf of Mexico and ascend Northern Gulf of Mexico Drainages to reproduce early in the year (January-May). The juveniles spend the majority of the year in these freshwater systems before emigrating out to the Gulf of Mexico as late as December.

This dissertation focuses on the juvenile life stages that occur within the Northern Gulf of Mexico drainages. Spawning conditions of the river, as well as the habitat and diet, …

Stereo Matching Using A Modified Efficient Belief Propagation In A Level Set Framework, Stephen Goyer Rogers

Dissertations

Stereo matching determines correspondence between pixels in two or more images of the same scene taken from different angles; this can be handled either locally or globally. The two most common global approaches are belief propagation (BP) and graph cuts.

Efficient belief propagation (EBP), which is the most widely used BP approach, uses a multi-scale message passing strategy, an O(k) smoothness cost algorithm, and a bipartite message passing strategy to speed up the convergence of the standard BP approach. As in standard belief propagation, every pixel sends messages to and receives messages from its four neighboring pixels in EBP. Each …

Folate Receptor-Targeted Delivery Of Small Interfering Rna To Cancer Cells, Yilin Zhang

Dissertations

The vitamin folic acid (folate, FA) has been extensively explored as a targeting ligand to deliver a variety of diagnostic/prognostic/therapeutic agents into various tumors through the assistance of its receptor – the folate receptor (FR). FR is over-expressed in many types of human cancer and can mediate internalization of FA-conjugates through an endocytic pathway. The discovery of small interfering RNA (siRNA), which is cable of inducing potent gene silencing in a sequence-specific manner, provides an excellent molecular tool to suppress aberrant gene expression in malignancies, and therefore siRNA has the potential to revolutionize cancer therapeutics. Towards the goal of developing …

A Psychometric Investigation Of The Young Adult Social Behavior Scale (Yasb), Michelle Rene Augustin

Dissertations

Aggressive behavior is a serious public health concern that has resulted in several problems in contemporary society. Despite a considerable body of literature on human aggression, both popular and scientific, a focus on overt physical aggression has obscured other forms of aggression. As a result, considerably less is known about other, more subtle forms of aggression, such as relational aggression. Moreover, research on relational aggression, particularly among older adolescents and adults, has been hindered by the lack of psychometrically sound measures. Research in this area would be enhanced by the availability of such a measure, facilitating comparison of data across …

Geological And Ichthyological Investigations Into Palaeodrainage Hypothesis For The Tennessee River, Andrea Karen Persons

Dissertations

The course of the ancestral Tennessee River has been debated in both the geological and biological literature for over 100 years. Several of the proposed courses for the ancestral Tennessee place its course across the state of Mississippi. Geochemical analysis of sedimentary rocks in the Pascagoula River basin supports these hypotheses suggesting that the rocks in the Pascagoula basin were derived from the Highland Rim of Tennessee and northern Alabama, while geochemical analysis of rocks from the Pearl River basin point to deposition from a mixture of sources including the ancestral Mississippi River and perhaps the ancestral Tennessee. To delve …
