The Relationship Between A Measure Of Dogmatism And Retention Of Rogerian And Skinnerian Concepts, Richard A. Carpenter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present study attempted to investigate the relationship between a subject's degree of dogmatism and his attitudes towards the different theoretical positions held by B. F. Skinner and Carl Rogers regarding the control of man. This study utilized selective retention as an indicator of subjects' attitudes. No significant difference was found between Skinner's and Rogers' on their retention of high, medium, and low dogmatism groups. There was also a non-significant correlation between subjects' scores on the retention of Sinner's and Rogers' concept and subjects' dogmatism scores.

Regulation Of Rabbit Testicular Capsular Motility: The Interaction Of Prostaglandins, Acetylcholine And Sympathomimetic Agents, James L. Hargrove

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The regulation of the contractility and intratesticular pressure of rabbit testes was studied. The effects of, and interactions among, prostaglandins (PGs) E₁ and F_2α testosterone, acetylcholine, epinephrine and norepinephrine were ascertained both in vitro and in vivo. All of these compounds, except for high concentrations of PGE₁ and testosterone, stimulated the testicular capsule to contract. PGE₁ at low concentrations potentiated the contractions produced by epinephrine and acetylcholine. Above 10^-7M, PGE₁ inhibited contractions caused by PGF_2α epinephrine or acetylcholine. Testosterone inhibited contractions caused by PGF_2α in vitro.

Monoamine Oxidase As A Target Enzyme In Pineal And Testicular Tissue: Adrenal Cortical Steroids And Arginine Vasotocin, Randall James Merrill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of the research was twofold: (a) To ascertain what effects the adrenal glucocorticoids and catecholamines have on pineal N-acetyltransferase and monoamine oxidase activity, and (b) to observe what effect arginine vasotocin (a pineal polypeptide) has on testicular monoamine oxidase activity.

Rat pineal N-acetyltransferase activity was numerically increased when rats were injected with cortisol. It was increased significantly when the animals were injected with cortisol plus norepinephrine. Adrenal demedullation significantly increased N-acetyltransferase activity in starved rats when compared with intact control animals. Moreover, bovine pineal monoamine oxidase activity was markedly inhibited in a dose-dependent manner when incubated in vitro …

Factors Relating To Diapause In The Alfalfa Weevil Parasite Bathyplectes Curculionis (Thomson), David S. Parrish

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Biological and ecological factors regulating diapause in the ichneumonid parasite of the alfalfa weevil, Bathyplectes curculionis (Thomson), were studied. In most experiments, both parasites and weevil larvae were maintained in the environmental conditions under study from the emergence of the adult parasite until the evaluation of results.

The factors either preventing or inducing diapause in B. curculionis were found to be an interaction of environmental factors. A long scotophase with cool temperatures prevented diapause. The percentage of nondiapausing parasites increased as the scotophase was increased to 15 hours. Over 15 hours of scotophase, fewer nondiapausing parasites were produced. The optimum …

An Analysis Of Sound Communication In The Water Vole, Microtus Richardsoni (Rodentia: Microtinae), Dane R. Tang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adult members of the species Microtus richardsoni were used to study the importance of acoustic communication in these voles. Tests were run with single individuals and nonbreeding pairs of voles to obtain recordings and sonagraphs of sounds emitted during exploration of a new cage, agonistic encounters, encounters with a potential predator and in response to miscellaneous aversive stimuli. Of the four groups of tests conducted, sounds were used by M. richardsoni during the last three. The results of this study showed that the water vole emitted ten different call types or sounds. These sounds were separated by similarity into Group …

The Reproductive Cycle Of Male Uinta Ground Squirrels And Its Relationship To Pineal N-Acetyltransferase And Monoamine Oxidase In The Testes, Hypothalamus And Pituitary, Robert Alexander Palmer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study was made of the reproductive cycle of male Uinta ground squirrels (Spermophilus armatus) during the activity seasons of 1973 and 1974 and during the aestivation/hibernation (A/H) period of 1973-1974. Physiological data collected were compared to changes in monoamine oxidase (MAO) activity of the testes, pituitary and hypothalamus and to pineal N-acetyltransferase activity.

Male Uinta ground squirrels began emerging from their burrows on April 12, 1973, and April 8, 1974, with average body weights of 302 g and 301 g, respectively. Body weight did not increase greatly during breeding, but rose rapidly to over a 500 g …

A Fine-Structural Study Of Aberrant Meiotic Cytokinesis In An Autosomal Male Sterile Mutant (Ms(2)3r) Of Drosophila Melonogaster, Laura J. Laughran

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The ultrastructure of abnormal meiotic cytokinesis in an autosomal male sterile mutant of Drosophila melanogaster is described. In the mutant ms(2)3R mitotic cytokinesis proceeds normally, but abnormal meiotic divisions give rise to four spermatids developing in one cytoplasmic mass. The contractile ring which is responsible for cell constriction during cytokinesis appears to form and function normally during meiosis. Ring canals which form intercellular bridges between synchronously developing spermatids are also apparently normal. However, there is an apparent adhesion and subsequent disintegration of the furrow membranes after division is completed. In addition to double membrane fragments in areas of open …

Detection Of Neonatal Calf Diarrhea Virus (Ncdv) And Human Infant Reolike Diarrhea Virus, Martin Wyatt Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to develop a diagnostic test and conduct a survey for the neonatal calf diarrhea virus (NCDV) and human infant reolike diarrhea virus. Two immunologic methods were developed in this investigation.

Immune electron microscopy (IEM) and the fluorescent viral precipitin test (FVPT) are the methods used to detect NCDV and the human virus. Both methods are based upon the principle that viral aggregates form when the virus is reacted with anti-NCDV antibody. Aggregates in the IEM method are negatively stained and observed with the use of an electron microscope. Fluorescein labeled antibody is used in …

Effect Of Ronnel On The Honey Bee, William P. Nye

All PIRU Publications

LD₅₀ for worker honey bees of unknown ages exposed to topical applications was 1.5 micrograms/bee in 24 hours. LD₅₀ for similar bees fed ronnel in sugar syrup was 3.0 micrograms/bee in 24 hours. Honey bees did not visit materials treated with ronnel in laboratory tests where bees had a choice between food with and without ronnel added.
