The Applicability Of A Habitat Rating System For Low Gradient Streams In Wisconsin To Low Gradient Coldwater Streams In Northern Michigan, Eric Lawrence Forward
The Applicability Of A Habitat Rating System For Low Gradient Streams In Wisconsin To Low Gradient Coldwater Streams In Northern Michigan, Eric Lawrence Forward
Masters Theses
Habitat and fish assemblage data were collected on 12 streams in northern Michigan to assess the applicability of a habitat rating system developed for low gradient streams in Wisconsin in determining stream health in low gradient coldwater streams in northern Michigan. An Index of Biotic Integrity (IBI) developed for coldwater streams in the upper Midwest was used as the measure of stream health. Principal components analysis was used to select a small subset of habitat variables to describe the variation in IBI scores. The seven habitat variables chosen to describe the variation in IBI scores in the final model included: …

Shrinkage And Strength Characterizations Of Concrete Containing Supplementary Cementing Materials, Aniruddha Chatterjee
Shrinkage And Strength Characterizations Of Concrete Containing Supplementary Cementing Materials, Aniruddha Chatterjee
Graduate Theses, Dissertations, and Problem Reports (ETD)
Considerable differences in drying shrinkage strains and compressive strengths are observed in HPC containing supplementary cementing materials from normal concrete (without any supplementary cementing material). The differences in these properties due to addition of supplementary cementing materials occur because of different quantity of C-S-H gel formation. This limits the application to HPC of standard prediction equation for shrinkage and strength of normal concrete.;Therefore in this study a novel technique has been used to estimate the C-S-H gel for cement pastes containing supplementary cementing materials in varying replacement proportions and combinations. New shrinkage and compressive strength models have been developed using …
Comparison Of Chestnut Canker Treatment Procedures For Hypovirus Introduction, Brian C. Bell
Comparison Of Chestnut Canker Treatment Procedures For Hypovirus Introduction, Brian C. Bell
Graduate Theses, Dissertations, and Problem Reports (ETD)
Historically, hypovirulent strains of Cryphonectria parasitica have been introduced into cankers principally by inoculating wounds made to the margin of cankers. Twelve hypovirus introduction methods were tested. Seventy-two trees were inoculated in June 2002 with an orange-pigmented virulent strain of C. parasitica (two inoculations per tree). After 11 weeks, the resulting cankers were treated with a brown-pigmented hypovirulent C. parasitica isolate using one of the following methods: (1) a non-invasive treatment where the inoculum was painted onto the canker surface; (2) an invasive treatment where the canker face was wounded with a sharp blade prior to the painting application of …
Identity Development And Empathy As Related To Creative Activity Participation, Shana L. Blackshire
Identity Development And Empathy As Related To Creative Activity Participation, Shana L. Blackshire
Graduate Theses, Dissertations, and Problem Reports (ETD)
The focus of this study was the associations between identity, empathy as an emotional construct, and participation in creatively focused activities among adolescents in a largely rural population. A series of measures to assess identity status, the ego strength of fidelity, empathy, and level of participation in creative activities were administered to 212 male and 320 female adolescents in grades nine through eleven at public high schools in Appalachia. Analyses indicated that while the expected relationship between creative activity participation and identity was not statistically significant, gender may heavily influence that relationship as a mediating variable. Empathy, however, was found …
Potential Mechanisms Linking Nutrition And Neuroendocrine Control Of Reproduction In The Sheep, Adam Bradley Dobbins
Potential Mechanisms Linking Nutrition And Neuroendocrine Control Of Reproduction In The Sheep, Adam Bradley Dobbins
Graduate Theses, Dissertations, and Problem Reports (ETD)
Nutrition and reproduction are linked in that the nutritional status of an individual influences its reproductive performance, i.e. an individual in negative energy balance will have decreased ability to reproduce. The mechanisms in which nutrition influences reproduction are not understood. My data suggest that reductions in lutenizing hormone secretion resulting from photoperiod-induced increases in sensitivity to testosterone negative feedback may be mediated, at least in part, by elevated neuropeptide Y (NPY), a hypothalamic neuropeptide shown to alter gonadotropin releasing hormone release and potently affect food intake. The results from my second study support our hypothesis that the growth hormone mediated …
Natural Gas Exploration Associated With Fracture Systems In Alleghenian Thrust Faults In The Greenbrier Formation, Southern West Virginia, Craig A. Edmonds
Natural Gas Exploration Associated With Fracture Systems In Alleghenian Thrust Faults In The Greenbrier Formation, Southern West Virginia, Craig A. Edmonds
Graduate Theses, Dissertations, and Problem Reports (ETD)
A hydrocarbon play has been identified in southern West Virginia targeting the intersection of thrust faults with specific Mississippian reservoirs. Late Paleozoic sandstone and limestone reservoirs are traditional pays of the study area, often yielding economic natural gas production, with initial production rates ranging between 100 to 200 Mcf per day per well. In contrast, production rates from wells that encounter faults often exceed 500 Mcf per day. We believe this prolific production results from secondary fracture porosity and enhanced permeability from fracture zones associated with thrust faults, providing a conduit to the Union Oolite reservoir member of the Greenbrier …

Specific Aspects Of Social Anxiety Related To Children's Peer Sociometric Status, Abby H. Friedman
Specific Aspects Of Social Anxiety Related To Children's Peer Sociometric Status, Abby H. Friedman
Graduate Theses, Dissertations, and Problem Reports (ETD)
The present study examined the association between specific aspects of social anxiety and sociometric status. Participants included 268 children in grades 4, 5, and 6. The children completed the Social Anxiety Scale for Children-Revised (SASC-R) and the Social Phobia and Anxiety Inventory for Children (SPAI-C). A sociometric nomination procedure was used to categorize participants into sociometric status groups (i.e., neglected, rejected, controversial, popular, and average). Results replicated and extended previous literature. Neglected children scored the highest on both measures of social anxiety, followed by rejected children. This was one of the first investigations to associate socometric status with SPAI-C factor …

This study focused on lysine catabolism by the lysine alpha-ketoglutarate reductase (LKR) pathway in rainbow trout (RBT). Selective breeding based on feed efficiency in 2 strains (A and B) of RBT generated 2 families within each strain. Eight fish from each of the four families were randomly allotted to individual tanks. Fish were fed until satiation for 3 wks at which time four fish within each family were randomly selected for 2 wks of starvation. After the 2 wk starvation, all fish were harvested. Hepatic in-vitro LKR activity and lysine oxidation (LOX) were measured as was LKR mRNA abundance. Strain …
Factors Underlying Stalking And Harassing Behavior In A College Population, Jill Johansson-Love
Factors Underlying Stalking And Harassing Behavior In A College Population, Jill Johansson-Love
Graduate Theses, Dissertations, and Problem Reports (ETD)
At the high end of unwanted pursuit behavior is stalking. This study, using questionnaires, investigated a sample of 48, college females, identified as potential stalkers. Factors examined included: demographic information, social desirability, psychological functioning, attachment, motive, rape myth acceptance, adversarial sexual beliefs, criminal thinking styles, and the actual unwanted pursuit behavior. Hypotheses regarding the criminal thinking styles of the individuals engaging in harassing and stalking behavior were supported at the .05 level. These findings indicate that harassers and stalkers exhibit criminal thinking patterns, such as sacrificing internal control to exert control over the external environment and justifying behavior by externalizing …

Factors Controlling Landslide Initiation As A Result Of July 2001 High-Precipitation Events In A Section Of The Lower New River Gorge, West Virginia, M. Patrick Kish
Graduate Theses, Dissertations, and Problem Reports (ETD)
Several geologic and physical factors affect the location of landslides associated with the July 2001 high precipitation events in Lower New River Gorge, West Virginia. The surficial geology of the heavily mined landscape was mapped using ArcGis 8.3 and four specific factors related to the landslides were identified. Road building was shown statistically to have a positive influence on the location of landslides. Slope aspect, slope angles, and elevation were also shown to have strong relationships with landslide initiations.;A landslide initiation risk map was created by overlaying the physical and geological factors favorable for landslide initiation. The risk map outlines …
Stream Ecosystem Response To Mitigative Limestone Treatment In Acid-Impaired, Central Appalachian Streams, Sarah Elizabeth Mcclurg
Stream Ecosystem Response To Mitigative Limestone Treatment In Acid-Impaired, Central Appalachian Streams, Sarah Elizabeth Mcclurg
Graduate Theses, Dissertations, and Problem Reports (ETD)
We quantified water chemistry, primary production, and benthic macroinvertebrate and fish community structure in 20 Central Appalachian streams: 4 acidic streams, 8 naturally circumneutral streams, and 8 historically acidic streams treated annually with limestone sand over varying lengths of time. The objective was to determine the extent of chemical and biological recovery and temporal trends in the recovery process of limestone treated streams compared to circumneutral reference conditions in Central Appalachia. Results indicate that the application of limestone sand to acidic streams is effective in fully and immediately recovering some of the chemical and biological characteristics of naturally functioning stream …

Examination Of Experimentally Engineered Larval Fish Habitat In The Marmet Pool, Kanawha River, West Virginia, Jonathan M. Niles
Graduate Theses, Dissertations, and Problem Reports (ETD)
In rivers, velocity shelters are thought to serve as limiting factors in the retention and recruitment of young fish. Such shelters are formed in backwaters and tributaries, however these areas are limited in the Marmet Pool of the Kanawha River, West Virginia. In response to this concern, several structures that are thought to serve as low velocity zones were placed within the Marmet Pool. This study was conducted to evaluate the experimental rock structures (Finger and Zipper Dikes) as potential mitigation for navigational impact and to determine which sampling gears are best to sample these shallow, structurally diverse areas. The …

Exposures To Silica And Inducers Of Xenobiotic Metabolism In The Rat Lung, Lori A. Battelli
Exposures To Silica And Inducers Of Xenobiotic Metabolism In The Rat Lung, Lori A. Battelli
Graduate Theses, Dissertations, and Problem Reports (ETD)
CYP1A1 metabolizes polycyclic aromatic hydrocarbons (PAHs), such as those in cigarettes, to reactive intermediates which interact with DNA and lead to cancer. Silica is a lung carcinogen. Epidemiology studies of silica and lung cancer are not all positive. A possible explanation for these inconsistencies may be that silica is a modifier of PAH metabolism and, thus, cigarette smoke carcinogenesis. We hypothesize that crystalline silica exposure alters CYP1A1 expression, thereby modifying lung cancer risk. Rats exposed to both crystalline silica and the model PAH, beta-naphthoflavone (NF), a CYP1A1 inducer have significantly decreased CYP1A1 enzymatic activity and CYP1A1 protein expression. In the …

Today, more than 75 percent of women ages 25--34 and 75 percent of women with a child under six years of age participate in the labor force. When both parents work outside the home, they often want to send their child to preschool, but preschool classes aren't always available, and often those that are available are the government programs that are open only to those of lower socio-economic status.;In addition, parents often want to support the emergent literacy of their children and help prepare them for kindergarten but aren't sure of how to provide the type of assistance that might …
Use Of Commercial Cfd Software For Assessing The Performance Of Personal Aerosol Samplers, Aaron J. Bird
Use Of Commercial Cfd Software For Assessing The Performance Of Personal Aerosol Samplers, Aaron J. Bird
Graduate Theses, Dissertations, and Problem Reports (ETD)
Accurate performance of personal aerosol samplers is critical for industrial hygienists' successful efforts to protect workers. Performance assessments of personal samplers are necessarily conducted in controlled environments so unknown sources of variability will not influence the results. This is done in order that samplers may be used with confidence for monitoring workplace air quality. These performance evaluations are usually conducted in wind tunnels. However, recent advances in high-performance cluster computing---together with advanced flow modeling software---have made it possible to evaluate sampler performance with computer simulations. This was done in the current research. Simulations were conducted for air and particle behavior …

Hematotoxicity Of Heptachlor, Sarah Vanessa Meads Dodson
Graduate Theses, Dissertations, and Problem Reports (ETD)
Hematotoxicity has been documented in adults exposed to high levels of organochlorine pesticides. Our studies revealed that prenatal exposure to the organochlorine pesticide heptachlor resulted in alteration of lymphocyte development, while myeloid cell development was spared. To further investigate effects of heptachlor on lymphoid cells, we evaluated direct exposure of this compound on pro-B and pre-B cells. In these studies, the pro-B cell line C1.92 and the pre-B cell line 70Z/3 demonstrated concentration-dependent decreases in proliferation following heptachlor exposure. Pro-B cell viability decreased significantly; however, pre-B cell viability was not altered. Further investigation into mechanisms of diminished cell proliferation revealed …
Three Essays On The Profitability, Risk, And Viability Of Family Firms In A Developing Economy, Kamol Khaemasunun
Three Essays On The Profitability, Risk, And Viability Of Family Firms In A Developing Economy, Kamol Khaemasunun
Graduate Theses, Dissertations, and Problem Reports (ETD)
The objective of this dissertation is to examine the family firms in term of profit, risk and the probability of their survival in developing countries. The first chapter gives an introduction to this study. The second chapter provides an analysis of family businesses in regard to their performance, since there have been claims in the popular press that family-centered "crony capitalism" significantly contributed to the Asian financial crisis of 1997. Small, tightly focused firms can, however, be well managed by family hierarchies. As firms grow and diversify, family management is often displaced by diffuse ownership and independent managers. Between these …

The study expected that (a) positive affect would hold a significant, positive synchronous relation with physical activity and (b) negative affect would hold a significant, negative synchronous relation with physical activity over six consecutive days. Women over age 55 (M = 71.5, SD = 9.4) participated by completing four daily assessments (8am, 12pm, 4pm, 8pm) of positive and negative affect and physical activity on a hand-held computer Monday through Saturday. Affect was measured using the Positive and Negative Affect Schedule …
Pain-Related Acceptance And Physical Impairment In Individuals With Chronic Pain, Kevin E. Vowles
Pain-Related Acceptance And Physical Impairment In Individuals With Chronic Pain, Kevin E. Vowles
Graduate Theses, Dissertations, and Problem Reports (ETD)
Treatments using acceptance-based approaches have been utilized for a variety of health care concerns with data regarding their application to a chronic pain population recently emerging. These approaches may be particularly suited to chronic pain as they target potentially harmful avoidance and ineffective pain control strategies. Acceptance of chronic pain is related to psychosocial constructs generally (e.g., depression, pain-related anxiety); however, its relation to the overt behavioral variables associated with such states remains unevaluated. The present investigation assessed the specific effects of an acceptance-based versus control-based instructional set on demonstrated physical impairment in 74 individuals with chronic low back pain. …
