A Sourcebook For The Interpretation Of Traditional Dance By Outdoor Museums And Historic Sites, Jan Alm

Library Faculty & Staff Publications

Folklife scholars often produce work which is valuable to outdoor museums and historic sites. Folklife scholars deal with functional, contextual, emic, and interdisciplinary studies--all approaches which produce valuable interpretive data for museums and sites. This thesis is an example of folklife work designed for use in the museum field.

Outdoor museums and historic sites are increasingly involved with the interpretation of social and emotional life. Because it is a social and emotional event, dance can be a valuable part of this interpretation.

Sites and museums developing programs of traditional dance interpretation may find it helpful to follow several steps: 1.) …

Aggregation Behavior Of Aplomyiopsis Xylota (Diptera: Tachinidae), Frank J. Messina

Biology Faculty Publications

The tachinid A. xylota is a common parasitoid of larvae of Trirhabda virgata and T. borealis (Coleoptera: Chrysomelidae) in central New York [USA]. Flies aggregated on herbaceous vegetation along the borders between old fields and more shaded habitats (shrubby fields or woodlots). Aggregations comprised from less than 100 to a few thousand individuals, almost all of which were male. Males continuously perched and moved about in sun flecks on the vegetation and frequently grappled with each other. In the old field adjacent to the primary aggregation site, the tachinid sex ratio was strongly skewed toward females. Aggregations of A. xylota …

Waste Oil Biodegradation And Changes In Microbial Populations In An Arid Soil, Susan Ollett Mcdonald

Biology

The biological degradation of waste oil in an arid soil was studied at the 16 ha EPA oil disposal site near Ogden Bay Wildlife Refuge, Utah. Upon addition of oil and fertilizer (N, P) amendments, the hydrocarbon and lipolytic utilizing microbial populations increased to 108g-1 soil. Decreases in numbers of these populations correlated with the decrease in amount of residual oil in the soil. Changes in actinomycetes, carbohydrate utilizers, fungi, and anaerobic bacterial populations were not significantly correlated with oil degradation. Increases in species known to be hydrocarbon utilizers (Corynebacterium, Pseudomonas, Arthrobacter, Acinetobacter, Flavobacterium, Penicillium, and Aspergillus) were noted upon …

The Immediate Effects Of Root Pruning On Plant Water Relations Of Helianthus Annuus L., George Murchie Briggs

Biology

This study investigated the effects of root pruning in plant water potential, leaf conductivity and transpiration. Roots of four-week-old Helianthus annuus L., grown either in soil or solution, were pruned 25, 50 or 75% and the plants observed for several days following pruning. The taproots of the plants had been removed at the age of one week. This resulted in a root system of more or less equal members. Pruning was performed on selected laterals where they attached to the taproot stub. Observations on root distribution within the soil indicated that the roots had a relatively uniform distribution both before …

Isozyme Variation Among Geographic Populations Of The Colorado Potato Beetle, Leptinotarsa Decemlineata (Say), James Western Jacobson

Biology

This study was conducted to estimate the arrount of genetic variability present in geographic populations of the Colorado potato beetle, Leptinotarsa decemlineata (Say)(Coleoptera:Chrysomelidae), and to estimate the degree of genetic divergence between these populations. Enzyme products of 11 genetic loci (Acid Phosphatase, Esterase-1, Esterase-2, Fumarase, Glucose-6-phosphate Dehydrogenase, Glutamate Oxalo-acetate Transaminase, α-Glycerophosphate Dehydrogenase, Isocitrate Dehydrogenase, Malic Dehydrogenase, Malic Enzyme, Superoxide Dismutase) were examined by starch gel electrophoresis for 11 geographic populations from the United States, Mexico, and Europe. The average heterozygosity of L. decemlineata was found to be 0. 201+ 0.043 with an average proportion of polymorphic loci of 0.516+0.078. The …

Studies To Further Evaluate Reoviruses As An Indicator Of Enteric Virus Pollution, Dennis Jack Adams

Biology

A protamine sulfate precipitation procedure capable of concentrating IV/PIV reovirus and rotavirus particles from large volumes of diverse waters was developed. This procedure can be used effectively with rapid immunofluorescent cell assay techniques. Protamine precipitation of both reovirus and rotavirus particles recovered 88 to 100 percent of the viruses added to water, 79 to 100 percent from secondary sewage effluent without suspended solids, 79 to 95 percent from secondary effluent with suspended solids and 82 to 100 percent from raw sewage. Twenty-two precipitations of naturally occuring reovirus particles recovered an average of 5.0 x 104/l from raw sewage. This study …

Protoheme Formation In Barley In Response To Light And 5-Aminolevulinic Acid, Ibraheem M. Ameen

Biology

In vivo 5-aminolevulinic acid (ALA) was found to accumulate in the highest concentration during induced-greening by light flashes, in 8- to 9-day-old etiolated barley leaves, 4.5 and 9.0 hrs after light induction. Maximal concentrations of ALA were accumulated using 75 to 100 mM levulinic acid (LA), a competitive inhibitor of ALA-dehydratase. Only small quantities of ALA were detected in LA-treated tissues incubated in the dark. Protoheme concentrations increased significantly following two flashes of light, 9.0 and 24 hrs after light induction. Similar increases in protoheme were observed after 24 hrs of continuous light compared to no increase in dark controls. …

Characterization Of Bacteriophage For Selected Halobacterium Including Species Isolated From The Great Salt Lake, Utah, Tim J. Leslie

Biology

Twelve strains of Halobacterium halobium from the national Research Council of Canada (NRC) and three extreme halophiles isolated from the Great Salt Lake were used as hosts in an attempt to obtain bacteriophages from the lake. We were successful with 7 NRC hosts and two of the lake hosts for a total of 8 (one was later lost) bacteriophages. All eight have proven to be DNA phages. As determined from melting point the GC ratios fell into three distinct groups: a low 48-51 group, an intermediate 54 group, a high 62-65 group, and a group of 3 phages with no …

Electron Microscopic Observation Of The Development Of A Bovine Rotavirus In Madin-Darby Bovine Kidney Cells, Corey H. Mjaatvedt

Biology

The purpose of this study was to describe some of the ultrastructural events which occur in Madin-Darby bovine kidney cells infected with bovine rotavirus. Several observations were made in this study which have not been previously reported. First, distension of the rough endoplasmic reticulum cisternae was observed to occur before the entry of virus particles. Second, an increase in ribosome-like particles in the cytoplasm was seen to occur. Third, bundles of microfilaments were often seen near the nuclear envelope, mitochondria, and the rough endoplasmic reticulum. Fourth, two different densities of viroplasm were observed. Fifth, progeny virus particles were observed in …

Primary Genetic Analysis Of Bovine Rotavirus, John B. Syverud

Biology

Cell-culture adapted bovine rotavirus was inactivated by varying exposures to ultraviolet light. The purpose was twofold: (1) to ascertain if efficient recombination would be demonstrated with rotavirus and (2) to determine optimal radiation dosages required to induce lethal mutations while retaining a relatively high efficiency of recombination. When assayed by the immuno-fluorescent cell counting method, the irradiated virus exhibited the phenomenon of multiplicity reactivation, suggesting the existence of a mechanism of genetic recombination. Once it had been determined that the double-stranded genome was suitable for additional genetic studies, a modified plaque assay was employed to screen plaque-purified bovine rotavirus for …

The Ecological Relationship Between Pikas And Marmots In Northern Utah, Andrew G. Goliszek

Biology

1. Pikas coexisting in areas with marmots gathered marmot scats along with vegetation for their haypiles during the summer and fall months. In these areas, haypiles were much smaller than those in areas that did not contain marmot populations. 2. Winter survival rates of pikas which coexisted with marmots were high even though haypiles on the average were small. This high rate of survival is attributed to the energy content in marmot scats which increased the total energy available in the haypiles. 3. The consumption rate of haypile vegetation by pikas in the lab decreased with the addition of marmot …

The Effect Of Trypsin On Polypeptide Composition And Infectivity Of Bovine, Simian, And Porcine Rotaviruses, John C. Roth

Biology

Bovine, simian, porcine, and human rotaviruses exhibited 8.0, 10.3, 35.4 and 3.2 fold infectivity enhancement in the presence of trypsin although optimal conditions of treatment varied between strains. Infectious titers of bovine and simian rotavirus preparations treated with 10 μg/ml trypsin decreased substantially over a one hour incubation period at 37° C. Serial passage of rotaviruses in cells without trypsin enhancement resulted in significant losses of infectivity with each passage until no infectious virus could be detected. A specific, trypsin-mediated cleavage of rotavirus structural polypeptide P3, which was consistent between rotavirus strains, resulted in the formation of two major cleavage …

Nucleotide Sequence Homology Between Rotaviruses, Jai Myung Yang

Biology

By coelectrophoresis in polyacrylamide gels, bovine, simian, and porcine rotaviruses exhibited different migration patterns in their double stranded RNA genome. There was less variation between bovine and simian rotavirus migration patterns than between bovine and porcine rotavirus patterns. Nucleotide sequence homology determined by hybridization between 3H labeled double stranded RNA and in vitro produced single stranded RNA showed 74 percent homology between bovine and simian rotaviruses, and 8 percent homology between bovine and porcine rotaviruses. The lack of a close relationship between bovine and porcine rotaviruses was confirmed by hybridization between 3H labeled, in vitro produced, single stranded RNA and …

Evaluation Of Three Insect Chemosterilants (Hempa, Theotepa, And 2, 5 Dichloro-2, 4 Dinitro Benzenesulfonanilide) For Their Potential As Anti-Coccidial Agents In Mice And Chickens, Mikky A. Amoudi

Biology

Neither (insect chemosterilants) hempa nor thiotepa showed any anti-coccidial action against Eimeria vermiformis when administered orally at the rate of 0.33 mg per mouse. These doses were calculated from the LD50 data for each of the drugs in mice. There was, however, an apparent increase in oocyst discharge and also delay in the patent period. On the other hand, young chickens infected with Eimeria tenella and then treated with thiotepa and 2, 5 dichloro-2, 4 dinitro benzenesulfonanilide at different concentrations showed a significant decrease in oocyst production with increase of drug concentration.

Male Infertility And Excessive Neonatal Kit Loss In Finely-Bred Dark Mink (Mustela Vison), Michael Davies Groesbeck

Biology

A series of investigations were undertaken to ascertain the cause(s) of excessive male infertility and neonatal kit mortality in finely-bred dark mink. Two mechanisms of testicular sperm transport were examined, testicular capsular contractions and seminiferous tubular contractions, and found to be the same in fertile and infertile dark mink. Spontaneous testicular capsular contractions were absent in both groups of mink. Seminiferous tubular contractions were present in both groups and this appears to be the primary means of sperm transport in the mink testis. Epididymides from infertile animals were devoid of sperm and showed signs of epithelial degeneration (i.e., sperm granuloma). …

Effects Of The Herbicide Simazine Upon Production In A Two Member Aquatic Food Chain, John Gerald Carter

Biology

The direct effects of simazine, an s-triazine herbicide, upon the green alga, Chlamydomonas reinhardii; and the invertebrate, Daphnia pulex, were studied by exposure of both organisms to different concentrations of simazine over long time periods. The effects of simazine upon growth and reproduction in Daphnia pulex were evaluated using both C. reinhardii and mixed bacterial culture as a food source. A simulation model was developed to assess the effects of simazine introduction into natural aquatic systems. Simazine in concentrations of 0.5ppm and above was shown to inhibit growth in cultures of C. reinhardii. Daphnia pulex reproduction and growth increased as …

Ecological Energetics And Foraging Behavior Of Wintering Bald Eagles, Mark Victor Stalmaster

Biology

The ecological energetics and foraging ecology of wintering bald eagles (Haliaeetus leucocephalus) were studied for 2 years on the Nooksack River in northwestern Washington and in the laboratory at Utah State University. During 36 food consumption trials, daily consumption by 4 winter-acclimatized eagles was 92.0 g/kg on a chum salmon (Oncorhynchus keta) diet, 74.8 g/kg on a black-tailed jack-rabbit (Lepus californicus) diet, and 65.1 g/kg on a mallard duck (Anas platyrhynchos) diet which was inversely related to the wet energy contents (0.90, 1.22, and 1.96 kcal/g) of the diets, respectively. Daily consumption for combined diets was 88.4 g/kg at -10 …

Pollination And Seed Production Of The Onions Allium Cepa L. And Allium Acuminatum Hook, Cynthia L. Hatley

Biology

Pollination and seed production of the commercial onion, Allium cepa, and a native onion, A. acuminatum, were studied from 1978 to 1980. Insect densities on five fertile (male fertile) onion cultivars grown in Utah were high and there was a positive linear relationship between insect density and flower density. Insect densities on the cultivars were significantly different, suggesting differences in attractiveness of the cultivars. At peak bloom, pollination success was high and a mean of 91% of the flower styles examined contained pollen tubes. In four of the cultivars, 60% or greater of the flowers on an umbel set seed. …

The Inhibition Of Reoviruses, Rotaviruses And Orbiviruses By Selected Antiviral Substances, Donald Frederick Smee

Biology

Known RNA virus inhibitors were evaluated in vitro and in vivo to determine if any had specific inhibitory effects on reo-, rota- and orbivirus infections. Test compounds included 1-ß-D-ribofuranosyl-1,2,4-triazole-3-carboxamide (ribavirin), 3-deazaguanine (3-DG), 3-deazauridine (3-DU), and 9-(S)-(2,3-dihydroxypropyl) adenine ([S]-DHPA). Certain selected studies were also run with the following ribavirin derivatives: ribavirin 2' ,3' ,5'-triacetate, ribavirin 5'-monophosphate and ribavirin 5'-triphosphate. Viruses included types 1, 2, and 3 reovirus; bovine, porcine and simian rotaviruses; and bluetongue and Colorado tick fever orbiviruses. Results of the in vitro antiviral studies indicated ribavirin to be the most potent anti-reovirus agent, and 3-DG the strongest rota- and …

Approaches To Adult Probationary Supervision: A Positive Perspective, Douglas Wilson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The field of probationary supervision today is marked by division and confusion. The probation officer who attempts to define the most effective approach to supervision is confronted with conflicting advice or, perhaps even worse, no advice at all. As Allen, Carlson, and Parks (1979) point out:

• In summary, if we ask which caseload management strategies have been shown to be the more effective or efficient, we must answer that too little research has been done in this area to come to any definitive conclusion. (p. 67)

In spite of the lack of research to provide a "definitive conclusion," the literature …

The Emergence Of An Afro-American Society In Colonial Amelia County Virginia, Carol Noble Funk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The eighteenth century is a critical time in a study of American slavery. The colonial years witnessed the development of cultural, social and demographic processes affecting African and Afro-American slaves, the result of which was an Afro-American culture and society, unique to this nation. The slave family and kin network system of the antebellum south and the post Civil War era had its genesis in the decades preceeding the Revolutionary War.

There have been many studies done on slavery in colonial Virginia, but with few exceptions they have focused on the wealthy planters residing in the tidewater counties. They describe …

Effect Of Mild Water Stress And Enhanced Ultraviolet-B Irradiation On Leaf Growth Of Rumex Obtusifolius L. And Rumex Patientia L. (Polygonaceae)., Steve R. Holman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Leaves of Rumex obtusifolius L. and R. patientia L.were exposed to combinations of mild water stress and enhanced ultraviolet-B irradiation during their ontogeny. Two UV-B treatments (enhanced UV-B and control) and three water stress treatments (-0.0 MPa, -0.2 MPa and -0.4 MPa rooting medium matric potentials) were employed. The impact of the stress interaction was assessed on the basis of changes in leaf area, average adaxial epidermal cell size, and total number of adaxial epidermal cells per leaf. Although the level of UV-B irradiation applied was insufficient to significantly alter leaf growth at any given water stress, UV-B did interact …
