Methods To Evaluate And Predict Student Success In Introduction To Animal Science At Western Kentucky University, Matthew Deppe

Masters Theses & Specialist Projects

Outcomes assessment is the process of determining student progress in a class or academic program. Students, (n = 306), from six freshman-level introductory animal science classes at Western Kentucky University (WKU) were given subjective and objective evaluation instruments on the first and last day of class. Students self evaluated competencies on each of forty-nine course outcomes using a scale of 1-100. Twenty-one demographic questions were also answered. Students were given the same 50-question examination following completion of the subjective assessment on the first and last day of class. Student high school performance measures including the American College Test scores (ACT), …

Within-Litter Birth Weight Variation In The Domestic Pig And Its Relation To Pre-Weaning Survival, Weight Gain, And Variation In Weaning Weights, Barry N. Milligan, David Fraser, Donald L. Kramer

Ontogeny Collection

To determine the relationship between within-litter birth weight variation and pre-weaning survival and weight gain, and to provide practical guidance on fostering low-birth-weight piglets, we analyzed piglet survival and weight gain in litters of piglets from 52 sows followed through eight consecutive parities. Litters with high variation in birth weight had more deaths, especially if the litter’s mean birth weight was low. High variation in birth weight was also associated with high variation in weaning weight, but was not significantly related to mean weaning weight. Piglets with birth weights well below the range of most of the litter (‘low-birth-weight piglets’) …

Fisheries Research Report No. 132 - A Review Of Food Availability, Sea Water Characteristics And Bivalve Growth Performance At Coastal Culture Sites In Temperate And Warm Temperate Regions Of The World, Sidney A. Saxby

Fisheries Research Reports

The suitability of a coastal area for bivalve farming, as well as the density at which bivalves can be farmed in that area, is limited by the available food supply and other environmental variables. In this review, a range of successful and marginal bivalve growing areas in temperate and warm temperate coastal areas around the world are characterised. These include areas of high food and nutrient levels, such as Saldanha Bay in South Africa, and the Seto Inland Sea, Japan, through to more oligotrophic areas, typified by parts of the South Australian coastline and the Mediterranean Sea. The latter areas …

Reseeding Of Grazing Gastropods And Bivalves Into The Marine Environment In Western Australia, Jane Borg

Fisheries Management Papers

The Department of Fisheries does not want to embark on what is ‘new territory’ in Western Australia without a policy framework to define what is to happen, why it is to happen, and what will happen if the project does or does not succeed. This paper therefore attempts to do three things. 1. It sets in place accepted definitions of reseeding and stock enhancement within the general context of fisheries management in Western Australia. 2. It discusses the policy issues associated with reseeding grazing gastropods and bivalves into the natural environment. 3. It proposes a framework or process to be …

Estimating Population Numbers Of Black Bears (Ursus Americanus) In Eastern Kentucky Using Microsatellite Analysis, Kelly Vowels

Masters Theses & Specialist Projects

Black bears (Ursus americanus) occur sporadically in eastern Kentucky, and there is some evidence that a breeding population exists. In order to establish management practices to enhance the black bear population in Kentucky, information about this population is needed. However, until recently, no population size estimate has been available. Gathering information on black bears is difficult because black bears are elusive animals. The development of new molecular methods has made it easier to track and gather information on black bear populations, including estimates of population size. Molecular markers are particularly useful in that they do not require physical contact with …

Effects Of Prescribed Burning On Vegetation And Fuel Loading In Three East Texas State Parks, S. Rideout, Brian P. Oswald

Faculty Publications

-This study was conducted to evaluate the initial effectiveness of prescribed burning in the ecological restoration of forests within selected parks in east Texas. Twenty-four permanent plots were installed to monitor fuel loads, overstory, sapling, seedling, shrub and herbaceous layers within bum and control units of Mission Tejas, Tyler and Village Creek state parks. Measurements were taken during the summers of 1999 and 2000. Prescribed burning was conducted between these sampling periods in early spring 2ooo. Results indicated that the current applications of prescribed burning do not significantly influence vegetation or fuels. Sustained drought, prior management practices and imposed local …

The Relationship Of Demographic Characteristics To Consumer Knowledge Of Diet And Health Relationships To Intake Of Soy Foods And Soy Supplements, Ashlyn K. Hosokawa

All-Inclusive List of Electronic Theses and Dissertations

In 1999, the FDA approved a health claim for a relationship between intake of 25 grams of soy protein per day and reduced risk of heart disease. Literature suggests that consumers are increasingly krtowledgeable about diet and disease risk factors. While gender, age, race, and family history cannot be altered, diet may be changed to decrease risks. This study explored the relationship of demographic characteristics to consumer knowledge and use of some of the more popular soy products and supplements. Surveys were completed by a random sample of 100 attendees at area festivals and 100 nutrition professionals at a national …

Sodium Dodecyl Sulfate Hypersensitivity Of Clpp And Clpb Mutants Of Escherichia Coli, Soumitra Rajagopal, Narasimhan Sudarsan, Kenneth W. Nickerson

Papers in Microbiology

We studied the hypersensitivity of clpP and clpB mutants of Escherichia coli to sodium dodecyl sulfate (SDS). Both wild-type E. coli MC4100 and lon mutants grew in the presence of 10% SDS, whereas isogenic clpP and clpB single mutants could not grow above 0.5% SDS and clpA and clpX single mutants could not grow above 5.0% SDS. For wild-type E. coli, cellular ClpP levels as determined by Western immunoblot analysis increased ca. sixfold as the levels of added SDS increased from 0 to 2%. Capsular colanic acid, measured as uronic acid, increased ca. sixfold as the levels of added …

Testing For Genetic Evidence Of Population Expansion And Contraction: An Empirical Analysis Of Microsatellite Dna Variation Using A Hierarchical Bayesian Model, Jay F. Storz, Mark Beaumont

Jay F. Storz Publications

The role of past climatic change in shaping the distributions of tropical rain forest vertebrates is central to long-standing hypotheses about the legacy of the Quaternary ice ages. One approach to testing such hypotheses is to use genetic data to infer the demographic history of codistributed species. Population genetic theory that relates the structure of allelic genealogies to historical changes in effective population size can be used to detect a past history of demographic expansion or contraction. The fruit bats Cynopterus sphinx and C. brachyotis (Chiroptera: Pteropodidae) exhibit markedly different distribution patterns across the Indomalayan region and therefore represent an …

Human Exposure To Herpesvirus B–Seropositive Macaques, Bali, Indonesia, Gregory A. Engel, Lisa Jones-Engel, Michael A. Schillaci, Komang Gde Suaryana, Artha Putra, Agustin Fuentes, Richard Henkel

All Faculty Scholarship for the College of the Sciences

Herpesvirus B (Cercopithecine herpesvirus 1) has been implicated as the cause of approximately 40 cases of meningoencephalitis affecting persons in direct or indirect contact with laboratory macaques. However, the threat of herpesvirus B in nonlaboratory settings worldwide remains to be addressed. We investigated the potential for exposure to herpesvirus B in workers at a “monkey forest” (a temple that has become a tourist attraction because of its monkeys) in Bali, Indonesia. In July 2000, 105 workers at the Sangeh Monkey Forest in Central Bali were surveyed about contact with macaques (Macaca fascicularis). Nearly half of those interviewed had …

The Uv (Ribotoxic) Stress Response Of Human Keratinocytes Involves The Unexpected Uncoupling Of The Ras-Extracellular Signal-Regulated Kinase Signaling Cascade From The Activated Epidermal Growth Factor Receptor, Mihail S. Iordanov, Remy J. Choi, Olga P. Ryabinina, Thanh-Hoai Dinh, Robert K. Bright, Bruce E. Magun

CUP Faculty Research

In mammals, UVB radiation is of biological relevance primarily for the cells of the epidermis. We report here the existence of a UVB response that is specific for proliferating human epidermal keratinocytes. Unlike other cell types that also display a UVB response, keratinocytes respond to UVB irradiation with a transient but potent downregulation of the Ras-extracellular signal-regulated kinase (ERK) signaling cascade. The downregulation of ERK precedes a profound decrease in the steady-state levels of cyclin D1, a mediator of the proliferative action of ERK. Keratinocytes exhibit high constitutive activity of the Ras-ERK signaling cascade even in culture medium lacking supplemental …

A Mitochondrial Dna Phylogeny Of The Leptodactylus Fuscus Species-Complex (Leptodactylidae: Anura, Arley Camargo

Master's Theses

Leptodactylus fuscus is a broadly distributed frog species in the Neotropical region. Previous allozymic evidence supported the hypothesis of L. fuscus as a composite of several species. However, morphological and advertisement call data supported the hypothesis of a single-species taxon. These competing hypotheses were evaluated using cladistic analyses of mitochondrial DNA sequences. Fragments of 12S rRNA, 16S rRNA, and ND1 protein-coding genes from 17 populations were sequenced. Phylogenetic analyses were performed using: maximum parsimony, maximum likelihood, and Bayesian analysis. Data sets were analyzed separately and combined. Analyses of the combined data set show four exclusive clades of L. fuscus: …

Designing A Low Water Use Landscape, Teresa Cerny, Kelly L. Kopp, Maggie Wolf, Debbie Amundsen

All Current Publications

A landscape design should meet the needs of the people who will use and maintain the area while incorporating the site’s existing environmental conditions into the design. Water is a limiting resource in Utah, so designing the landscape to efficiently use water is important. Conserving water in the landscape can be accomplished by selecting low water use plants, designing and scheduling irrigation systems efficiently, grouping plants according to their water requirements, and using hardscaping materials (patios, stone paths, decks, etc.) appropriately to reduce the area requiring irrigation.

A Regional Gis-Based Analysis Of Elk Habitat Suitability In Northwestern Nebraska, Justin W. Fischer

School of Natural Resources: Dissertations, Theses, and Student Research

The need to accurately assess the use and suitability of elk (Cervus elaphus spp.) habitat at regional scales will continue to increase as human development encroaches into what was once optimum elk habitat. The objectives of this research were to calculate the relative proportions of habitat use by elk in the Pine Ridge region of Northwestern Nebraska from a set of radio-collared elk locations and generate a habitat suitability model. Habitat variables (Iandcover type, aspect, slope, distance to a road, road density, and distance from the ponderosa pine edge) were measured for each elk location (n = 5,787 dating …

Competition For Pollination Between An Invasive Species (Purple Loosestrife) And A Native Congener, Beverly J. Brown, Randall J. Mitchell, Shirley A. Graham

Biology Faculty Research

Invasive species are frequently regarded as Superlative competitors that can vegetatively crowd Out natives, but little is known about whether invasives call compete for pollination services with native plants. We hypothesized that, when the showy invasive species Lythrum salicaria (purple loosestrife) was present, pollinator visitation and seed set would be reduced in a native congener, L. alatum (winged loosestrife). To test this hypothesis, we constructed mixed and monospecific plots of the two species. Over two years of study, we found that L. salicaria significantly reduced both pollinator visitation and seed set in L. alatum. Furthermore, pollinators moved frequently between the …

Effects Of Ethanol On The Toxicity And Metabolism Of Acetonitrile And Acrylonitrile, Nancy Ochoa-Garza

Theses and Dissertations - UTB/UTPA

This study examined the effects of ethanol on the toxicities and metabolism of two aliphatic nitriles: acetonitrile and acrylonitrile (one unsaturated and one saturated aliphatic nitrile, respectively) in male Sprague-Dawley rats at four different time intervals. Toxicity signs were apparent in all animals given the nitrile dosage, but those treated with ethanol dosages showed signs of toxicity earlier than those treated with glucose dosages. Both of the nitrites were metabolized to cyanide and thiocyanate. The concentration levels of each metabolite was apparent at 2 and 3 g/kg ethanol dosage for acetonitrile and 3 and 4.5 g/kg ethanol dosage for acrylonitrile …

Effect Of Guanosine Tetraphosphate On Growth Rate And Stable Rna Synthesis In Escherichia Coli, Heather Anne Quintanilla

Theses and Dissertations - UTB/UTPA

Guanosine tetraphosphate (ppGpp) is a good candidate for a stable RNA synthesis regulator at different growth rates because: high ppGpp levels present during the stringent response are known to inhibit stable RNA synthesis, and there is an inverse correlation between ppGpp concentration and stable RNA synthesis at different growth rates. A system was constructed allowing the user to control intracellular ppGpp levels within the range characteristic of exponentially growing strains, while not allowing cells to adjust ppGpp in response to environmental changes. E. coli strains were transformed with a plasmid containing a truncated relA allele to provide ppGpp. Results show …

Re-Test Of Rhinocyllus Conicus Host Specificity, And The Prediction Of Ecological Risk In Biological Control, Amy E. Arnett, Svata M. Louda

School of Biological Sciences: Faculty Publications

Biological control is proposed as an ecological strategy to manage the threat of invasive plants, especially in natural areas. To pursue this strategy, we need to know that the host specificity criteria used to evaluate ecological risk with deliberate introduction of an exotic insect for biocontrol are sufficient to predict potential impact on native species. Host specificity is defined by adult feeding and oviposition preferences and larval development. One way to evaluate the criteria is to re-examine case histories where ecological effects are recorded, such as that of Rhinocyllus conicus Frölich. This flower head weevil, released in North America in …

Linder-Aronson S Analysis Using Rhinomanometry And Newtom, Noel Moser

Loma Linda University Electronic Theses, Dissertations & Projects

Investigations into the effects of airway patency on craniofacial development are essential to ensure that interceptive orthodontic treatment provides the maximum benefit to the patient. The aims of this study were to (1) compare the size of the nasopharyngeal airway space on lateral cephalometric and 3D volumetric radiographs to determine if volumetric scans can be of greater diagnostic value than a lateral cephalometric film in determining the degree of airway blockage or patency and (2) to examine the correlation between functional airway resistance, as evaluated by rhinomanometry, and radiographic constriction due to nasal turbinate and adenoid size.
