Food Habits Of The Allegheny Woodrat (Neotoma Magister ), Nikole Lee Castleberry

Graduate Theses, Dissertations, and Problem Reports (ETD)

Regional declines in Allegheny woodrat (Neotoma magister ) populations suggest a better understanding of the ecology of this species is needed for proper management. I described seasonal food habits of the Allegheny woodrat in the Ridge and Valley and Allegheny Plateau physiographic provinces of West Virginia and Virginia using microhistological techniques. In the Allegheny Plateau, the top 5 food items were fungi, blueberries ( Vaccinium spp.), acorns (Quercus spp.), ferns ( Dryopteris spp.), and lichens. In the Ridge and Valley woodrats ate primarily blackberry (Rubus spp.) leaves, fungi, greenbrier (Smilax spp.) leaves, acorns, and oak leaves. Additionally, we examined the …

Factors Influencing Ruffed Grouse Productivity And Chick Survival In West Virginia, Christopher A. Dobony May 2000

Factors Influencing Ruffed Grouse Productivity And Chick Survival In West Virginia, Christopher A. Dobony

Graduate Theses, Dissertations, and Problem Reports (ETD)

I examined productivity, chick mortality, and factors influencing ruffed grouse (Bonasa umbellus) chick survival in West Virginia during 1998--1999. The proportion of hens that attempted to nest, hen success, average clutch size, and hatch dates were similar between age classes, between sites, and between years. Hatch dates were similar between age classes and between sites. Depredation was the major cause of nest failure. I examined 2 types of radio transmitter attachment methods (glue-on and collar type) to determine mortality and survival in ≤3-day-old grouse chicks. Glue-on transmitters performed poorly, whereas collar types had excellent retention time. Chick survival was low …

Aspects Of Attention That Affect Compliance And General Behavior In Disruptive And Typical Children, Holly Ann Filcheck May 2000

Aspects Of Attention That Affect Compliance And General Behavior In Disruptive And Typical Children, Holly Ann Filcheck

Graduate Theses, Dissertations, and Problem Reports (ETD)

Currently, there is some controversy concerning whether praise affects compliance and behavior other than compliance (i.e., general behavior) in children with disruptive behaviors. It is unclear whether it is praise or other aspects of general attention, such as descriptions and enthusiasm, that influences children's behavior. The current study examined the effects of enthusiastic praise, non-enthusiastic praise, and non-enthusiastic description on child compliance (measured by the Compliance Test) and general behavior (measured by the Marble-in-the-Hole Game) in 15 children with disruptive behavior problems and 15 typical children. Results indicated that the participants had significantly higher rates of compliance in the non-enthusiastic …

Acute Silica Toxicity: Attenuation By Amiodarone-Induced Pulmonary Phospholipidosis., J M. Antonini, C M. Mccloud, M J. Reasor Jan 2000

Acute Silica Toxicity: Attenuation By Amiodarone-Induced Pulmonary Phospholipidosis., J M. Antonini, C M. Mccloud, M J. Reasor

Faculty & Staff Scholarship

Exposure to the toxic mineral dust silica has been shown to produce an acute inflammatory response in the lungs of both humans and laboratory animals. Coating silica with phospholipids reduces its toxicity when studied with in vitro systems. The drug amiodarone increases phospholipid within the cells, airways, and alveoli of the lungs. This increase in phospholipid is due to amiodarone's ability to inhibit phospholipase activity within alveolar macrophages (AMs) and whole lung. The purpose of this study was to determine whether the amiodarone-induced increase in pulmonary phospholipid would protect the lungs from acute damage caused by the intratracheal instillation of …

Paradoxical Interventions With Severe Conduct-Disordered Adolescents: Research Of Treatment Effectiveness., Marsha Anne Mills

Graduate Theses, Dissertations, and Problem Reports (ETD)

Paradoxical interventions are therapeutic techniques in which the therapist appears to promote the worsening or continuation of the problem rather than its removal. The objective of this treatment is to lessen or eliminate the problematic behavior through the unusual means of encouraging it. Only two previous studies have empirically evaluated these techniques with resistant and defiant youths; those results suggested that paradoxical interventions may be effective with severely conduct-disordered adolescents. This study applied the techniques of symptom scheduling and restraining with three conduct-disordered adolescents residing in a therapeutic group home. The experimental design was a nonconcurrent multiple baseline across participants; …

Study Of Human Head Impact: Brain Tissue Constitutive Models., Toru Aida

Graduate Theses, Dissertations, and Problem Reports (ETD)

Finite element (FE) models of the human head have been used extensively to assess engineering response parameters (pressure, shear strain, etc.) that constitute the basis of various injury criteria including the Head Injury Criterion (HIC). There is a wide range of brain material properties reported in the literature, and linear elastic models are frequently used for the brain tissue which is viscoelastic in nature. The uncertainty around the properties of brain tissue affects the perceived importance of those response parameters under consideration. In this research, the effect on head injury criteria of five reported viscoelastic brain models and their linear …

The Relationships Between Snags And Cavity-Nesting Birds In A Gypsy Moth-Impacted Forest., Christopher Ryan Showalter Jan 2000

The Relationships Between Snags And Cavity-Nesting Birds In A Gypsy Moth-Impacted Forest., Christopher Ryan Showalter

Graduate Theses, Dissertations, and Problem Reports (ETD)

Gypsy moth defoliation can result in the death of trees and create snags (standing dead trees), a resource vital to cavity-nesting species. With this in mind, population trends of 11 cavity-nesting birds and their relationship to snags were investigated from 1984 to 1999 in an area that was impacted by gypsy moth defoliation. Data from before a major gypsy moth outbreak (1984-1986), during (1987-1988), and after (1989-1999) enabled inferences about this forest bird community to be made. The combined abundance of the 11 cavity-nesting species examined increased significantly during the years immediately after the outbreak (1989 – 1993) followed by …

Knowledge Acquisition From Video, Video With Animated Graphics, And Laboratory Experience: Predictors For Adolescents With Mild Mental Impairments., John D. Foshay

Graduate Theses, Dissertations, and Problem Reports (ETD)

The movement toward assistive technology (AT) and access to the general curriculum provided by the 1997 Amendments to the Individuals with Disabilities Education Act (IDEA) has resulted in the need to study instructional methods that employ computer-based multimedia. Although the definition of AT includes interactive multimedia (Blackhurst, 1997), there has been little research on the use of multimedia to provide access to the general education curriculum. The existing literature has provided a theoretical base and investigated the ability of multimedia presentations to improve academic skills, but has failed to identify instructional practices that promote such access through AT. This dissertation …

Endothelin-1 Gene Expression In The Porcine Ovary: Follicular Development., Hope Marie Sasway Jan 2000

Endothelin-1 Gene Expression In The Porcine Ovary: Follicular Development., Hope Marie Sasway

Graduate Theses, Dissertations, and Problem Reports (ETD)

Endothelin-1 (ET-1) is known to inhibit steroidogenesis in granulosa and luteal cells. This study investigates ET-1 gene expression to localize the source of synthesis. Previous studies showed the presence of ET-1 in porcine ovarian granulosa cell cultures. The present study provides the first evidence that gene expression of ET-1 occurs in the porcine ovary exclusively within the granulosa cells of antral follicles. ET-1 immunoreactivity was observed in 65.7% of the large antral follicles, particularly in more differentiated granulosa cells. An autocrine role for ET-1 is suggested because ET-1 binding sites were previously detected here. ET-1 expression and atresia (one aspect …

Legibility: How Precedents Established In Print Impact On-Screen And Dynamic Typography, Heidi Specht

Graduate Theses, Dissertations, and Problem Reports (ETD)

The printed word has been commonplace in society for over 500 years; the written word has been in existence for thousands. The primary intent of the written or printed word has historically been to be read. With that goal, rules and formats have developed over the centuries as aids to legibility. Naturally, these guidelines have been developed for the printed, or static typographic page. As our sophistication with and acceptance of technology grows, however, we increasingly turn to the computer or television screen for written information. Additionally, graphic designers and artists are questioning the role of the printed word as …
