Natal Dispersal And New Group Formation In Capybaras (Hydrochoerus Hydrochaeris) In A Seasonally Flooded Savanna Of Venezuela, Elizabeth Rae Congdon

Dissertations

This study examines natal dispersal and new group formation in capybaras (Hydrochoerus hydrochaeris) in a seasonally flooded savanna in Venezuela. The first section describes a novel approach to the study of dispersal that could be applied to many taxa. Dispersal is considered in three stages (emigration, transience, and immigration) and its proximate and ultimate mechanisms are clearly differentiated. The second chapter describes dispersal behavior in capybaras, including which individuals disperse, when, and to where. In the third chapter, I evaluate dispersal in capybaras with respect to social subordination and social cohesion hypotheses. In this population, some support was …

A Comparison Of An Individually Tailored And A Standardized Asthma Self-Management Education Program, Judy Ann Shackelford

Dissertations

Asthma is one of the most prevalent chronic diseases in the United States (Centers for Disease Control [CDC], 2003). According to the CDC (2003), prevalence of asthma continues to rise in epidemic proportions and is very costly. While asthma cannot be prevented or cured, it can be controlled to improve quality of life. Self-management is key to controlling asthma (CDC, 2003; National Heart, Lung, and Blood Institute [NHLBI], 2002). State of the science for asthma self-management establishes that health care costs decrease for self-management intervention groups (Lindberg et al, 2002; Thoonen et al, 2003).

Electron Beam Characterization Of Carbon Nanostructures, Eric Samuel Mandell

Dissertations

Atom-thick carbon nanostructures represent a class of novel materials that are of interest to those studying carbon's role in fossil fuel, hydrogen storage, scaled-down electronics, and other nanotechnology. Electron microscope images of "edge-on" graphene sheets show linear image features due to the projected potential of the sheets. Here, intensity profiles along these linear features can measure the curvature of the sheet, as well as the shape of the sheet (i.e. hexagonal, triangular). Also, electron diffraction powder profiles calculated for triangular graphene sheet shapes show a broadening of the low-frequency edge of diffraction rings, in comparison to those calculated for hexagonal …

Missouri Ozark Women's Experiences Of Living With Postpartum Depression Symptoms, Nathalie B. Williams

Dissertations

Depression is a serious complication of the postpartum period that affects not only women but their children and families as well. Rural women are of particular concern because of the significant barriers to health care that they experience as a result of isolation, poverty, traditional beliefs, and a lack of accessible and adequate health related services. A review of the literature to identify evidence based nursing interventions that focused on primary and secondary prevention of postpartum depression revealed few interventions and there were no studies identified that targeted or even included women living in rural areas of the United States. …

The Experience Of Technology Integration By Teacher Educators In Higher Education, Patricia Ann Suess

Dissertations

With the advancing use of technology globally, it is becoming essential for K-12 educators to have knowledge of educational technology and its appropriate classroom use. Thus, it is important for higher education faculty involved in the preparation of those K-12 teachers to achieve technology integration in their teacher education programs. It is not sufficient to simply provide computers and peripheral devices to future teachers. The critical issue is the way in which those tools are used to promote student learning. Therefore, it is necessary for faculty in higher education to model the use of technology as a teaching and learning …

Structural Changes And Neighborhood Homicide Trends In St. Louis, Missouri, 1980 - 2000: A Multi-Level And Spatial Analysis, Robert Jason Fornango

Dissertations

Social scientists have long observed strong correlations between social structure and violent crime rates at the neighborhood level. Yet little is known about the relationship between changes in social structure and violent crime trends. Furthermore, the spatial distribution of crime trends has received little attention in the literature. The dissertation explores the trajectories and spatial dynamics of neighborhood homicide rates and social structure in St. Louis, Missouri between 1980 and 2000. Multilevel growth curve models are used to describe the nature of, and variation in, census tract homicide trajectories as functions of structural characteristics and changes in those features. Exploratory …

Fiscal Impact Of American Indian Gaming On Non-Indian Local Governments, Courtney A. Andrews

Dissertations

Intense growth in American Indian gaming over the past two and a half decades has resulted in suggestions of impact on non-Indian communities with a resulting growth in tribal-local government interaction. Although there is mounting evidence of both positive and negative socio-economic impacts on non-Indian communities as a result of Indian gaming operations, to date, there has been very little exploration of the actual fiscal impact on non-Indian governments as a result of these operations. This thesis serves to examine this impact. This study uses a combination of an extensive literature review, tribal-local government survey, GIS techniques and a quantitative …

Attitudes Toward And Knowledge Of Affirmative Action In Higher Education, Erika Ann Carr

Dissertations

Affirmative action has become an increasingly important topic in higher education because colleges and universities are key battlegrounds regarding how affirmative action policies are enacted. Senior-level higher education administrators have historically taken the lead in shaping affirmative action policies in higher education, and knowing their own community's standpoints on the policies could assist them in deciding how to proceed in defending affirmative action in the face of increasing opposition.

This study measures individuals' attitudes toward and knowledge of affirmative action within one university in the state of Michigan, where affirmative action was banned through a state-wide election in November 2006. …

Evaluating The Effectiveness And Benefit-Cost Of Michigan Background Check Program Using Crime Opportunity Theory, Judith Brown Clarke

Adsorption Of Lead On Single And Mixed Solid Systems, Soumya Das

Dissertations

Metal oxy-hydroxides and phyllosilicate minerals play a significant role in the fate and transport of heavy metals in the environment (Bertsch and Seaman, 1999). Chemical speciation of metals affects their bioavailability and chemical reactivity (Stumm and Morgan, 1996). Surface complexation models (SCMs) based on equilibrium thermodynamic principles have been successfully used to quantify adsorption of heavy metals on pure solid minerals, including phyllosilicates and oxy-hydroxides. For natural sediments with mixed mineralogy, Davis et al. (1998) suggested two different SCM approaches, namely, the component additivity and generalized composite models. In this study, adsorption of lead on pure HFO, silica and kaolinite …

Audio-Assisted Reading With Digital Audiobooks For Upper Elementary Students With Reading Disabilities, Kelli J. Esteves

Dissertations

Audio-assisted reading has been used as an effective instructional intervention for students with learning disabilities (Carbo, 1978; Gilbert, Williams, & McLaughlin, 1996) and with struggling readers (Chomsky, 1976; Hollingsworth, 1978; Hoskisson & Krohm, 1974; Koskinen, Blum, Bisson, Phillips, Creamer, & Baker, 2000; Rasinski, 1990). The strategy involves reading along while listening to an audio recording of a fluent model (Evans, 1997).

The goal of this study was to compare the efficacy of audio-assisted reading with digital audiobooks against the traditional practice of sustained silent reading in terms of reading fluency rates and reading attitude scores with upper elementary students with …

Perceived Organizational Support And Ethical Work Climates As Predictors Of Turnover Intention Of Licensed Nurses In Skilled Nursing Facilities, Anna A. Filipova

Dissertations

The purpose of this study was twofold: (1) to replicate Victor and Cullen's (1987; 1988) studies to confirm whether ethical climates (ECs) arise in skilled nursing facilities (SNFs), and whether organizations and groups within organizations have identifiable ECs; and (2) to test a model that examines the effects of ECs and perceived organizational support (POS) on licensed nurses' turnover intention (TOI) through job satisfaction (JS) and organizational commitment (OC).

A cross-sectional survey design was implemented. Three hundred and fifty nine freestanding SNFs were selected in a midwestern state. While a total of 110 facilities (31%) agreed to participate, responses were …

A Mixed Methods Analysis Of The Concept Of Female Sexual Health, Laura C. Ford

Dissertations

The theoretical concept of health includes the ability to function physiologically, perceive a state of wellness, participate in social relationships, and be disease-free. Currently, the medical field approaches sexuality from a disease prevention and treatment perspective. Female sexual health must be understood holistically (i.e., emotionally, sociologically, and physiologically) for healthcare providers to help their patients optimize their sexual health; however, little research has been conducted from a holistic perspective. This study's purpose was to begin an exploration of the meaning of female sexual health.

This study utilized focus groups and a survey to explore the concept female sexual health as …

Quantum Properties Of Light Emitted By Dipole Nano-Laser, Talal Ghannam

Dissertations

Recent technological advances allow entire optical systems to be lithographically implanted on small silicon chips. These systems include tiny semiconductor lasers that function as light sources for digital optical signals. Future advances will rely on even smaller components. At the theoretical limit of this process, the smallest lasers will have an active medium consisting of a single atom (natural or artificial). Several suggestions for how this can be accomplished have already been published, such as nano-lasers based on photonic crystals and nano wires. In particular, the "dipole nanolaser" consists of a single quantum dot functioning as the active medium. It …

Synthesis, Study Of Self-Assembly, And Trivalent Lanthanide Metal Ion Recognition Characteristics Of Amphiphilic Acylpyrazolones And Amphiphilic Acylisoxazolones, Venkat Reddy Guduru

Dissertations

This research project focused on the separation of trivalent lanthanide metal ions by HPLC using amphiphilic acylpyrazolones and amphiphilic acylisoxazolones. The central hypothesis of our research project is that the nanoscale self-assembly nature of amphiphilic ligands (chelating lingads) can influence their metal ion recognition and separation. To test the central hypothesis, we have synthesized a family of novel amphiphilic ligands and employed them as model systems for the separation of trivalent lanthanide metal ions. Several novel intermediates such as 4-acylated. N -acylated, O -acylated pyrazolones and isoxazolones, have been efficiently synthesized and fully characterized.*

The trivalent lanthanide metal ion recognition …

Differences In Bachelors Degree Attainment: Are College Degrees A Function Of Habitus?, Colin S. Mccaleb

Dissertations

This study sought evidence that Pierre Bourdieu's habitus influences college graduation and college transferring patterns. Hypothesizing that low socio-economic students have to change their habitus in the elitist environment of higher education, two research questions were advanced to explore this phenomenon, the first asking if there was evidence consistent with the idea that habitus influenced graduation rates, the second question asking if there was evidence consistent with the idea that habitus influenced transferring patterns. Under each research question, several hypotheses were tested using descriptive statistics, analysis of variance, Chi square tests of independence, and logistic regressions. Income and civic participation …

Gender Disparity In Nigerian Education: Women’S Experience Of Barriers To Equal Educational Opportunity, Eugene Okoli

Dissertations

Discrepancies between males and females in access to schooling, school completion rates, and participation in employment opportunities are still more the norm in some regions of the world than others. Limited access to education plagues women in Nigeria as well as in Sub-Saharan Africa. Disparity in access to educational opportunity is a pressing gender equity issue in Nigeria (World Bank, 2003).

Relatively few studies have focused on obtaining the viewpoints of women who experience this phenomenon. To hear the voices of these women regarding how they gained or were denied access to education in the Nigerian context, a cross-section of …

Economic Impacts Of Casino Gambling On Rural Michigan Communities, Mark Steven Reece

Dissertations

When considering future casino development, it is important to know whether the magnitude of a casino's economic impact.

A way to understand the impact of adding a casino to a rural Michigan community is to study the economic changes during the 6 years surrounding casino's opening. If significant changes occur in population, employment, and commercial, industrial, and residential property values, it may be possible to attribute this change to the introduction of a casino.

Township level data is used for an index of annual percentage change, preceding and following an opening. This study tests for movement in the community's economics …

Estimating The Impact, Transmission Mechanism And Reaction Function Of Monetary Policy: A Factor-Augmented Vector Autoregressive (Favar) Approach, Dawit Legesse Senbet

Dissertations

This dissertation employs factor-augmented vector autoregressive (FAVAR) models to investigate the impact, transmission mechanism and reaction function of monetary policy. The recent development of augmenting dynamic factor analysis with the vector autoregressive (VAR) models, pioneered by Bernanke et al. (2005), has led to advances in monetary policy analysis. The new approach bases measurements of monetary policy on large data sets that approximate the true information set of policymakers. This is in contrast to low dimensional VAR models. The FAVAR model summarizes information from large data set by a few factors that are incorporated into VAR models.

The first essay investigates …
