Parenting Stress And Child Attachment: Child Age Of 10 And 36 Months/Father And Mother, Jeng Hyun Ok

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parents are the most affective human environmental resources to children. Although the influences from parents continue even after parents passed away, very young children (up to age 3) get the biggest impact from their parents. According to children's independency to parents, parents' psychological well-being determines children's emotional-social development. However, in parenting stress, children also have their own influence to parents in the family context. Regarding parenting stress, many studies have been dedicated to defining the occurrence, co-occurrence, and predictors of parenting stress of parents in various conditions.

This longitudinal research conducted from surveys with 201 Early Head Start families reexamines …

Bats And Mines: Evaluating Townsend's Big-Eared Bat Maternity Colony Response To Reclamation, Gabrielle F. Diamond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With the loss or modification of natural roosting habitat afforded by caves, abandoned mines have assumed increased importance as surrogate roosting sites for Townsend's big-eared bats (Corynorhinus townsendii) and other chiropteran species. However, increasing concerns for human safety have led to accelerated programs for mine closure. In efforts to protect roosting sites in mines showing significant bat activity, "bat compatible" gates are installed, thus allowing continued access to mine workings. Aside from ensuring public safety, these structures afford protection from disturbance to roosting bats. To date few posting-gating studies have been conducted to obtain information on the effects …

Breeding Behavior And Space Use Of Male And Female Mule Deer: An Examination Of Potential Risk Differences For Chronic Wasting Disease Infection, Leslie R. Mcfarlane

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The dynamics of pathogen and host relationships relative to disease transmission in wildlife populations are important ecological processes to understand, particularly since spatial dynamics of disease can be driven by movement, behavior, and dispersal of animals. Chronic Wasting Disease (CWD) is an example of this important interface, where little is known regarding origin of the disease or routes of transmission. Surveillance data for CWD in free-ranging mule deer indicates that breeding-age male deer have 2-4 times higher prevalence rates than females or younger age males. In an effort to understand differences that might increase risk for exposure to CWD infective …

Factors Influencing Epiphytic Lichen Communities In Aspen-Associated Forests Of The Bear River Range, Idaho And Utah, Paul C. Rogers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In western North America, quaking aspen (Populus tremuloides Michx.) is the most common hardwood in montane landscapes. Fire suppression, grazing, wildlife management practices, and climate patterns of the past century are some of the threats to aspen coverage in this region. Researchers are concerned that aspen-dependent species may be losing habitat, thereby threatening their long-term local and regional viability. Though lichens have a rich history as air pollution indicators, I believe that they may also be useful as a metric of community diversity associated with habitat change. To date, few studies have specifically examined the status of aspen's epiphytic lichen …

Psychosocial Variables And Their Relationship To Diabetic Outcome Among The Strong Heart Study Cohort, Brian D. O'Leary

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Diabetes mellitus is one of the leading causes of death and disability in the United Sates. Certain Native American groups have been harder hit than the mainstream population, both in prevalence of the disease and in rates of related complications. The highest known prevalence in the world is found among a Southwestern U.S. Tribe, and other Native American Tribes have demonstrated similar prevalence rates. It has been shown that certain psychological factors such as depression and hostility impact both the occurrence and outcome of certain diseases, including diabetes.

This study examined whether those individuals who have not met the criteria …

Efficacy Of A Cognitive-Behavioral Treatment For Weight Loss In Adults With Type 2 Diabetes, Kathy Wickersham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The prevalence of type 2 diabetes is increasing across all sociodemographic groups. Obesity and overweight are major risk factors in the development of the disease and in the development of complications. Conversely, weight loss improves glycemic control, which reduces likelihood of complications. Interventions combining cognitive and behavioral components show promise in addressing the problem of weight loss maintenance. The objective of this study was to test the efficacy of a cognitive-behavioral intervention. Participants were 54 adults diagnosed with type 2 diabetes randomly assigned to either a treatment group or a control. The assessment measures utilized in this study were the …

The Marriage Of Eolian Rock Properties And Deformation Of The Nugget Formation; Anschutz Ranch East Field: Northeast Utah And Southwest Wyoming, Dustin J. Keele

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Nugget Formation in the Anschutz Ranch East field, northeast Utah and southwest Wyoming, provides an exceptional example of how primary eolian rock properties have a considerable influence on the style of structural deformation. Both new and existing subsurface data were integrated for an overall characterization of sedimentologic and diagenetic heterogeneities, which demonstrate relationships with different styles of structural compartmentalization in reservoirs. The Anschutz Ranch East field is a large asymmetric anticlinal trap in the Utah-Wyoming thrust belt. Three cores were analyzed in order to investigate brittle deformation in eolian facies: dune, apron, and interdune. Selected cores are located along …

Pathologizing The Female Body: Phallocentrism In Western Science, Stephanie E. Libbon

Journal of International Women's Studies

In his well-known work Making Sex, Thomas Laqueur contends that the conception of human sexuality evolved from the ancient Greeks’ one-sex model to modernity’s two-sex model as events surrounding the French Revolution prompted a desire to see difference and therefore a need to create difference. In particular, Laqueur argues that it was the struggle for power between those advocating enfranchisement for women and those opposed to this which led to the reconstitution of the human body and in particular the female body. Extrapolating on Laqueur’s assertion that the female was conceived as an inferior version of the male in Antiquity …

The Fortunes And Misfortunes Of Women Rice Producers In Ndop, Cameroon And The Implications For Gender Roles, Lotsmart N. Fonjong, Mbah Fongkimeh Athanasia

Journal of International Women's Studies

In most communities in Cameroon, traditional norms mandate that rural women fulfill the reproductive roles of child bearing, home management and food provision for the family. Thus, these women are unable to exercise any influential economic voice- they can hardly earn income. Cash agriculture like rice production provides a possible outlet for the empowerment of these women in rice producing areas. However, this agricultural work would solve one problem for the women and create another. Any attempt to encourage these women to work outside their homes may increase their workload. This paper examines the situation of female rice farmers in …

China And Latin America: A Match Made In Trade Heaven Or Dependency Reloaded?, Meghan Skira

Senior Honors Projects

China’s economy is expanding rapidly, and the emerging powerhouse is searching for energy resources, raw materials, and markets to maintain its economic growth. China has shown an insatiable appetite for Latin American natural resources, commodities, and agricultural products, from oil to lumber to copper to soybeans. Trade values between the two regions increased greatly from $1.3 billion in 1980 to about $13 billion in 2000 to over $50 billion in 2005. Latin America has the raw materials that China needs to fuel its economic expansion and offers a large market for cheap Chinese manufactured goods. Many analysts claim that Sino-Latin …

Using Cross-Sectioned Multilayer Polymer Film And Surface Modification To Form Chemically Patterned Substrates , Chun Zhang

All Dissertations

Highly layered structures are important to micro- and nanofabrication technologies for understanding and controlling surface structures through manipulation of chemical and physical interactions. The objective of this work was to develop a new approach to create micro- and nanopatterned surfaces using multilayer polymer films of commercially available and inexpensive polymers instead of inorganic substrates. As an example, linear low density polyethylene (LLDPE) and ethylene-co-acrylic acid copolymer (EAA) were used as alternating inert and reactive polymers, respectively. Thin cross-sections of the multilayer molded sheets were prepared by ultra-microtoming.
As a precursor to the multilayer work, surface modification of EAA was conducted …

Biochemical Study Of Endonuclease V And Its Application In Mutation Scanning, Honghai Gao

All Dissertations

The integrity of the genetic information encoded by DNA is essential to all living organisms, yet the reactive bases of DNA are constantly attacked by endogenous and exogenous agents resulting in as many as one million individual molecular lesions per cell per day. Excessive DNA damage or deficiency in DNA repair enzymes may cause cancer, premature aging, and neurodegenerative diseases.
Endonuclease V (Endo V) is a DNA repair enzyme which can recognize all four types of DNA deamination products, specifically, uracil, hypoxanthine, xanthine and oxanine. It was also shown that endo V can recognize mismatches. We screened about 60 mutants …

Extraction Method Development And In Vivo And In Vitro Toxicity Studies Of The Etiologic Agent Of Avian Vacuolar Myelinopathy, Faith Wiley

All Dissertations

Avian vacuolar myelinopathy (AVM) is a neurological disease affecting birds in the southeastern United States. The cause of the disease has not yet been determined but is believed to be a naturally produced toxin and is associated with aquatic vegetation. Current research on AVM is limited to in vivo studies utilizing whole tissue or vegetative samples. The objectives of this research were to develop extraction methods for isolating the putative AVM toxin from vegetative samples and to develop an in vitro bioassay for detection and study of the toxin. Samples of vegetation were collected from reservoirs known to be affected …

Three Essays In Political Economy, Melissa Yeoh

All Dissertations

The first essay provides a theoretical framework that informs the ongoing debate regarding the effect of conservation easement subsidies on local property tax revenue. Supporters claim that conservation easements increase property tax revenue by providing environmental amenities that increase the value of adjacent properties. Critics argue that they decrease property tax revenue by lowering land values and shrinking the tax base. In instances when local property tax revenue decline due to the income tax deductibility of conservation easements, the decline is larger when the demand for land is more elastic, the proportion of non-agricultural land in the county is larger, …

Comparison Of Two Electrofishing Gears (Backpack And Parallel Wires) And Abundances Of Fishes Of The Upper Greenbrier River Drainage, Angela D. Burns

Graduate Theses, Dissertations, and Problem Reports (ETD)

The type of electrofishing gear influences capture efficiencies and abundance estimates of stream fishes. Few studies have examined the Holton and Sullivan (1954) parallel wires method of electrofishing. For this study, I modeled removal data with seven sampling occasions of three common species, western blacknose dace (Rhinichthys obtusus), fantail darter (Etheostoma flabellare), and mottled sculpin ( Cottus bairdi) from 10 paired sites in the upper Greenbrier River drainage, West Virginia, and estimated capture efficiencies of two electrofishing gear types (the Holton and Sullivan parallel wires method with alternating current and backpack units with pulsed-direct current). Ten candidate models represented alternative …

Development Of Water Production Type Curves For Horizontal Wells In Coalbed Methane Reservoirs, Praveen Kumar Burka Narayana

Graduate Theses, Dissertations, and Problem Reports (ETD)

Coalbed methane is an unconventional gas resource that consists of methane production from the coal seams. The key parameters for the evaluation of coalbed methane (CBM) prospects are the gas resources, reserves and deliverability. Coalbed methane reservoirs are dual-porosity media where the vast majority of the gas is stored in the low permeability coal matrix (primary porosity) by sorption. The flow to production wells, however, occurs through the coal's natural fracture system (secondary porosity), which stores relatively small amounts of gas, because coal matrix practically has no permeability.;For the gas to be released from the coal, its partial pressure must …

Regulation Of Alpha-1-Adrenoceptor-Mediated Contractions Of The Uterine Artery By Pkc, Hongying Zhang

Loma Linda University Electronic Theses, Dissertations & Projects

Pregnancy is associated with a significant decrease in uterine vascular tone and a striking increase in uterine blood flow, which ensures normal fetal development. Multiple mechanisms are involved in the adaptation of uterine artery contractility during pregnancy. Both protein kinase C (PKC) and activation of ai-adrenoceptors play important roles in the regulation of uterine artery contractility. In addition, PKC mediates the pregnancyassociated decrease in myogenic tone of the uterine artery, and interacts with ajadrenoceptors leading to modulation of ai-adrenoceptor-mediated contractions of vascular smooth muscle. Yet, whether or to what extent PKC regulates ai-adrenoceptormediated contractions of the uterine artery and their …

Cultural Icons And Urban Development In Asia: Economic Imperative, National Identity, And Global City Status, Lily Kong

Research Collection School of Social Sciences

Global cities are characterized by the multiplicity of flows that they are implicated in - flows of people, goods, services, ideas, and images. Yet, global cities do not derive their status only on the basis that they are networked nodes. They also require particular forms of cultural capital. Cities with global aspirations have thus increasingly recognized the need to accumulate cultural capital, for which one means is to create new urban spaces, in particular, new cultural urban spaces (e.g. grand theatres, museums, libraries). These often monumental structures are intended to support a vibrant cultural life, in order to attract and …

Design Effects In The Transition To Web-Based Surveys, Don A. Dillman, Jolene D. Smyth

Department of Sociology: Faculty Publications

Innovation within survey modes should always be mitigated by concerns about survey quality and in particular sampling, coverage, nonresponse, and measurement error. This is as true today with the development of web surveying as it was in the 1970s when telephone surveying was being developed. This paper focuses on measurement error in web surveys. Although Internet technology provides significant opportunities for innovation in survey design, systematic research has yet to be conducted on how most of the possible innovations might affect measurement error, leaving many survey designers “out in the cold.” This paper summarizes recent research to provide an overview …

Adults’ Responses To The Art Process And Interaction With Art Media, Madeline Couch

EVMS School of Health Professions Theses & Dissertations

The art materials are a major component in art therapy. Their actual usage in sessions with clients, especially with adults, has rarely been the topic of investigation. The ideas about the qualities and purposes that the art materials bring to art therapy sessions are based on older theories, which were created without evidence-based research. The purpose of this study was to gain an understanding of how adults interact with and react to art media. Five adult volunteers, who were not formally trained as artists and who did not regularly engage in artistic processes, participated in the study. The participants experimented …

An Analysis Of The Economic Impact Of Biodiesel Production In Illinois, Kelly Uphoff

Master's Theses - Economics

The production of biodiesel in the United States has expanded greatly in recent years. A factor contributing to the growth of this industry is the perception that renewable fuel production is an economic boon to state and local economies, particularly those of rural areas. This study estimates the economic impact of biodiesel production in the state of Illinois. Through input-output analysis and by simulating the industry using IMPLAN, the impact of a 10 million gallon per year plant using soy oil as its only feedstock is modeled. The estimated effect on output, employment, and other parameters is substantial. However, the …

Anti-Insect Defensive Behaviors Of Equines After West Nile Virus Infection, Linsey Renee Cozzie

West Nile Virus is an important arbovirus (virus transmitted by arthropods) that has recently affected the health of both humans and animals in the United States. West Nile fever was first identified in the US in 1999. West Nile virus (WNV), vectored by mosquitoes, has had a detrimental impact on domestic horse health with over 23,000 equine cases in the United States since 1999. Previous research has focused on how this disease progresses and affects equids days to weeks post infection. The purpose of this study was to evaluate permanent equine behavioral changes. Specifically, I examined if surviving this disease …

Seasonal Habitat Use Of The Florida Manatee (Trichecus Manatus Latirostris) In The Crystal River Natural Refuge With Regards To Natural And Anthropogenic Factors, Ryan Willard Berger

College of Graduate Studies: Theses & Dissertations

Natural and anthropogenic factors work together to influence species habitat use. Kings Bay in Crystal River, Florida serves as critical habitat for the Florida manatee, but is also used extensively by humans. This study documented the seasonal dispersion and behavioral patterns of manatees in Kings Bay with regards to natural and anthropogenic factors from May 2005-June 2006. Survey stations were established across the bay and the number of manatees, people in the water, and boats were counted. The behavioral patterns of four major states were recorded using focal animal observations. During the winter, manatees aggregated in areas containing both springs …

Infaunal Abundance And Diversity In Vegetated And Unvegetated Areas Of A Georgia Salt Marsh, Anthony Lee Zukoff

College of Graduate Studies: Theses & Dissertations

Various commercially important marine species are known to utilize the salt marsh; research has shown that marsh infauna play an important role in the diets of these species. The distribution and abundance of some of these infauna has been shown to be influenced by vegetative cover. In 2001, salt marshes along the coast of Georgia began to die, resulting in the loss of the dominant vegetation. During the summer of 2005, six 0.5 x 0.5 meter quadrats were haphazardly placed and set up permanently in the low marsh at two study sites along the Crooked River in vegetated and unvegetated …
