Effects Of Morrow's Honeysuckle Control And The Impact Of The Shrub On Invertebrates At Fort Necessity National Battlefield, Pennsylvania, Jason Patrick Love
Effects Of Morrow's Honeysuckle Control And The Impact Of The Shrub On Invertebrates At Fort Necessity National Battlefield, Pennsylvania, Jason Patrick Love
Graduate Theses, Dissertations, and Problem Reports
Lonicera morrowii (Morrow's honeysuckle) dominates a degraded meadow at Fort Necessity National Battlefield, Pennsylvania, U.S.A. We tested four removal methods of Morrow's honeysuckle during spring and autumn 2004. Cut, stump application of 20% glyphosate, and mechanical removal in autumn were not successful (<47% reduction), while mechanical removal in spring and foliar application of 2% glyphosate were somewhat successful (>66% reduction). We used a modified leaf blower to sample invertebrates at our site. Invertebrate biomass was lowest within the native shrub, Viburnum recognitum (southern arrowwood) (p<0.05). Biomass of larval leaf chewers was highest in the native shrub. Invertebrate abundance, biomass, and richness were reduced under dense thickets of Morrow's honeysuckle (p<0.05), due to low amount of herbaceous cover beneath the shrubs. The amount of leaf area consumed by herbivores was 10 times more on the native shrub. Overall, our findings reveal that the exotic shrubs negatively impact invertebrate communities.

Regulation Of Polymeric Immunoglobulin Receptor By Reovirus In Intestinal Epithelial Cells, Kasturi Pal
Graduate Theses, Dissertations, and Problem Reports
Most pathogens invade the human body through mucosal surfaces. Enteric viruses are one such group of pathogens that are of great public health significance because they cause a number of serious diseases including gastroenteritis, hepatitis and poliomyelitis. Gastrointestinal disease is the second most common cause of morbidity worldwide, with diarrhea ranking first among infectious diseases in the categories of frequency and mortality in children. The mucosal epithelium provides the first line of defense against invading pathogens by serving as the first sensors of microbial infection and launching an innate immune response that leads to the development of adaptive immunity. An …
Oxidative Stress In Skin Induced By Chemical And Physical Agents, Ashley Rebecca Murray
Oxidative Stress In Skin Induced By Chemical And Physical Agents, Ashley Rebecca Murray
Graduate Theses, Dissertations, and Problem Reports
Free radicals threaten various tissues and are involved in the development and progression of many pathological states and diseases. More than other tissues, the skin is exposed to a variety of chemical, environmental, and physical agents which are capable of inducing radical formation resulting in the development of oxidative stress. The skin possesses an elaborate antioxidant network to deal with reactive oxygen species (ROS); however, excessive exposure and/or radical production can overwhelm the antioxidant capabilities of the skin causing oxidative damage to proteins, DNA, and lipids. The central hypothesis of these studies is that exposure to oxidizible chemicals and/or environmental …

Effects Of Environmental Factors On The Paternal Brood Pouch And Sound Production In Two Sympatric Pipefish Species From The Chincoteague Bay, Virginia, Jennifer L. Ripley
Graduate Theses, Dissertations, and Problem Reports
Pipefishes and seahorses of the family Syngnathidae are important inhabitants of diminishing grass beds threatened by excessive nutrient loads, sedimentation, and chemical contaminants. This research examined the influence of these environmental factors on two sympatric pipefishes from the Chincoteague Bay, Virginia. Syngnathids are characterized by a unique mode of reproduction in which the male carries developing embryos in a placenta-like ventral brood pouch until the fry are free-swimming. Interspecific comparisons revealed differences in parental nutrient allocation to embryos. In Syngnathus fuscus, females produce nutritionally poor eggs and males implant developing embryos adjacent to blood vessels. The loose connection between eggs …
Social Status And Behavioral Observations Of Children Exhibiting Comorbid Anxiety And Adhd Symptoms, Daniel B. Chorney
Social Status And Behavioral Observations Of Children Exhibiting Comorbid Anxiety And Adhd Symptoms, Daniel B. Chorney
Graduate Theses, Dissertations, and Problem Reports
The development of strong and positive relationships early in childhood is key to later social adjustment. Many behaviors have been shown to be related to children's status among their peers, defining whether they will be seen as popular, rejected, neglected, controversial, or of average status in the child's peer group. Children who display anxious behaviors are often overlooked by their peers, while aggressive and disruptive behaviors can lead to rejection. A small proportion of students display both symptoms of anxiety and ADHD, and prior research fails to show what peer status group most represents these children, or what social interaction …

A Spatial Simultaneous Growth Equilibrium Modeling Of Agricultural Land Development In The Northeast United States, Yohannes G. Hailu
A Spatial Simultaneous Growth Equilibrium Modeling Of Agricultural Land Development In The Northeast United States, Yohannes G. Hailu
Graduate Theses, Dissertations, and Problem Reports
With population growth and expansion of economic activities, urbanized places have expanded; and with growing per capita income, residential location preferences have shifted towards suburban and rural locations. In many places, such new growth has been accommodated with the development of agricultural lands. The concern from natural resource economics perspective is that agricultural lands are multifunctional. They have production uses, for which there are efficient markets, and amenity and environmental benefits, for which there are no efficient markets to value these attributes. This multifunctionality and the possible under-valuation of agricultural lands, irreversibility of development, and speculative effects of development on …

The Mythical Speech Of Janine Antoni, Patrick L. Jones
The Mythical Speech Of Janine Antoni, Patrick L. Jones
Graduate Theses, Dissertations, and Problem Reports
The confrontation of societal myths has been a major concern of many female artists since the 1960s. However, confronting the ideological construction of myth is not enough to discredit it. The semiology of myth, according to Roland Barthes (1915-1980), simply absorbs this confrontation by placing the artist in the position of a signifier of the myth itself. Paradoxically, in order to discredit myth the artist must "speak the myth," in order to empty the ideological content of the myth through the adoption of mythical speech. This produces a counter-myth. Language as a vehicle of feminist expression has been a permeating …

An Evaluation Of Vibration And Other Effects On The Accuracy Of Grip And Push Force Recall, Thomas W. Mcdowell
An Evaluation Of Vibration And Other Effects On The Accuracy Of Grip And Push Force Recall, Thomas W. Mcdowell
Graduate Theses, Dissertations, and Problem Reports
Operators of vibratory hand tools can be at risk of developing health problems associated with repeated forceful actions and exposure to intense hand-transmitted vibration. To better assess health risks, comprehensive risk evaluations of these tasks must include quantitative assessments of hand-tool coupling forces. Researchers have used instrumentation for such measurements; but those techniques may be ill-suited for certain field environments. Psychophysical force-recall techniques have been proposed as alternatives to handle instrumentation. This study comprised two experiments that examined the effects of vibration and other factors upon force-recall accuracy and reliability. In each experiment, participants applied specific grip and push forces …

Empirical Analysis Of Software Reliability, Margaret L. Hamill
Empirical Analysis Of Software Reliability, Margaret L. Hamill
Graduate Theses, Dissertations, and Problem Reports
This thesis presents an empirical study of architecture-based software reliability based on large real case studies. It undoubtedly demonstrates the value of using open source software to empirically study software reliability. The major goal is to empirically analyze the applicability, adequacy and accuracy of architecture-based software reliability models. In both our studies we found evidence that the number of failures due to faults in more than one component is not insignificant. Consequently, existing models that make such simplifying assumptions must be improved to account for this phenomenon. This thesis' contributions include developing automatic methods for efficient extraction of necessary data …
Lossless Compression Of Hyperspectral Images, Sushil Kamalchand Jain
Lossless Compression Of Hyperspectral Images, Sushil Kamalchand Jain
Graduate Theses, Dissertations, and Problem Reports
Band ordering and the prediction scheme are the two major aspects of hyperspectral imaging which have been studied to improve the performance of the compression system. In the prediction module, we propose spatio-spectral prediction methods. Two non-linear spectral prediction methods have been proposed in this thesis. NPHI (Non-linear Prediction for Hyperspectral Images) is based on a band look-ahead technique wherein a reference band is included in the prediction of pixels in the current band. The prediction technique estimates the variation between the contexts of the two bands to modify the weights computed in the reference band to predict the pixels …
Predicting Inflation, And The Relationship Between Financial Integration, Financial *Development And Economic *Growth, Lillian T. Kamal
Predicting Inflation, And The Relationship Between Financial Integration, Financial *Development And Economic *Growth, Lillian T. Kamal
Graduate Theses, Dissertations, and Problem Reports
Three essays are presented. The first essay re-visits the P* model (developed by Hallman, Porter and Small, 1991) with an application to US data. The central idea behind the P* model is that the price level is determined by the money stock, output and velocity. This study brings together criticisms of the P* model together in an attempt to address the major concerns with an improvement upon the existing model. A horse race is then run between the original P* model, two variant P* models, and three other models---an atheoretic naive AR process and an ARMA process as well as …
Effect Of High Salt Intake On Arteriolar Responses To Metabolic Stimuli, Paul J. Marvar
Effect Of High Salt Intake On Arteriolar Responses To Metabolic Stimuli, Paul J. Marvar
Graduate Theses, Dissertations, and Problem Reports
Study I evaluated the possibility that a HS diet can reduce the arteriolar response to muscle contraction through reduced nitric oxide (NO) availability and increased reactive oxygen species (ROS) activity. Spinotrapezius muscle arterioles were examined in rats fed a normal salt (NS; 0.45%) or high salt (HS; 4%) diets. Arteriolar diameter responses to an increase in metabolic demand were significantly less in HS rats and these HS rats exhibited increased presence of arteriolar ROS. The attenuated responses to muscle contraction in HS rats were not restored in the presence of ROS scavengers, and inhibition of NO synthesis had no effect …

Adolescent Religiosity And Conformity To Parents: Is Sex A Moderator?, Rebecca Kim Summers
Adolescent Religiosity And Conformity To Parents: Is Sex A Moderator?, Rebecca Kim Summers
Graduate Theses, Dissertations, and Problem Reports
This study examines relations between adolescent reports of conformity to their parents and religiosity and if these are moderated by the sex of the adolescent and parent. Self-report data was collected from 121 ninth and tenth graders enrolled in three non-metropolitan high schools. Religiosity was measured by Schumm et al.'s (1991) modified version of Gorsuch and Venable's (1983) scales. Conformity to Parents was assessed using Peterson's (Peterson, Rollins, & Thomas, 1985) Conformity to Parents scales. Four regressions were used. Results indicate that females: (a) report higher levels of conformity to parents and religiosity than males and (b) that when adolescent …
Iqgap1 Knockdown Enhances The Endothelial Barrier In Vitro, Wentao Zhang
Iqgap1 Knockdown Enhances The Endothelial Barrier In Vitro, Wentao Zhang
Graduate Theses, Dissertations, and Problem Reports
IQGAP1 overexpression inhibits E-cadherin-mediated epithelial cell-cell adhesion by distabilizing the adherens junctions, and activated Rac1 and Cdc42 may prevent these effects by removing IQGAP1 from the adherens junction complex. In the present study, we determined if IQGAP1 associates with the adherens junction of endothelial cells and affects endothelial barrier function. In human umbilical vein endothelial cells (HUVECs), IQGAP1 associated with VE-cadherin, the catenins, beta, gamma, alpha, and p120, but not with N-cadherin or the tight junction proteins, occludin, claudin-5, and ZO-1. Detergent extracted most of the IQGAP1 associated with VE-cadherin. Treatment of endothelial cells with sphingosine-1-phosphate (S1P), which increases the …
Filling The Silence --An Iserian Reading Of Ilse Aichinger's Work, Julia Sonja Brassat
Filling The Silence --An Iserian Reading Of Ilse Aichinger's Work, Julia Sonja Brassat
Graduate Theses, Dissertations, and Problem Reports
The works of the Austrian writer Ilse Aichinger are often considered impenetrable and incomprehensible. Aichinger’s doubt about conventional language serves as the basis for her use of highly pictorial and complex linguistic constructions. Although many literary scholars have alluded to the impenetrability of Aichinger’s works, few attempts have been made to investigate the meaning of her texts. In his theory of aesthetic response, Wolfgang Iser explains that literary works contain vacancies in the system of the text that need to be filled by the reader’s imagination. They serve as an impetus for the reader, during the process of reading, to …

"The Relapse Of Reconstruction:" Railroad -Building, Party Warfare And White Supremacy In Blue Ridge North Carolina, 1854-1888., Paul D. Yandle
Graduate Theses, Dissertations, and Problem Reports
In the early twentieth century, the men who had led North Carolina's mountain counties through Civil War and Reconstruction were praised by those who followed them for two "accomplishments:" bringing much-needed railroad service to the mountains and preserving white rule in North Carolina. The completion of the Western North Carolina Railroad to the Tennessee line in 1882 was, indeed, noteworthy for the perseverance it showed over physical and political obstacles. The preservation of white rule was equally if not more noteworthy for the suffering it brought to African Americans statewide. However, both railroad service and white supremacy were seen at …
The Transtheoretical Model And Psychological Skills Training: Application And Implications With Elite Female Athletes, Linda Ann Keeler
The Transtheoretical Model And Psychological Skills Training: Application And Implications With Elite Female Athletes, Linda Ann Keeler
Graduate Theses, Dissertations, and Problem Reports
There is abundant empirical evidence supporting the benefits of psychological skills training (PST) on performance (Vealey, 1994). Despite evidence of how PST can help athletic performance, some athletes still do not readily adopt its use (Gould, Tammen, Murphy, & May, 1989). Rather than ignoring individuals that are not interested (Weinberg & Williams, 2001), one possible method of approach would be to apply the transtheoretical model of behavior change (TTM) to the use of PST (Grove, Norton, Van Raalte, & Brewer, 1999). This model suggests that behavior change is a progression through a series of stages (Prochaska & DiClemente, 1983). There …
Investigation Of Techniques And Effects Of Diesel Particulate Filter Cleaning, Nathaniel Moles
Investigation Of Techniques And Effects Of Diesel Particulate Filter Cleaning, Nathaniel Moles
Graduate Theses, Dissertations, and Problem Reports
As the emissions standards placed on diesel engine exhaust become more stringent, the use of exhaust aftertreatment devices such as diesel particulate filters has become a more attractive means to meet those standards. During the use of these filters some of the particulate captured, usually ash, begins to restrict the flow through the filter. This increases the backpressure in the exhaust system and requires routine cleaning maintenance. This study reviewed engine technology used to reduce particulate emissions and investigated the effects of off-line cleaning of diesel particulate filters using compressed air and water flowing in the reverse direction of the …
