The Effect Of Photoperiod On The Regressive Phase Of The Ovarian Cycle Of The Lizard, Anolis Carolinensis., John Dickens Pinch

Master's Theses

The effects of constant photoperiod (14 hours of light) and decreasing photoperiod (13-8 hours of light) on the regressive phase of the ovarian cycle of the lizard Anolis carolinensis were investigated. Changes in body, liver, ovary and oviduct weights were measured and microscopic examinations of several ovarian parameters were made. In both light regimens body and liver weights decreased over the first four weeks of the experiment but both increased at the sixth week. In addition, ovary weight was highly variable but exhibited a decreasing trend and oviduct weight decreased. There were decreases in the number of previtellogonic follicles and …

Retention As A Function Of Transfer Paradign And Introversion-Extroversion, Glenna F. Hasslacher

Master's Theses

In an effort to investigate the effects of personality on paired-associate learning, sixty students from the Univer­ sity of Richmond were separated into three groups of extro­ vert, control, and introvert, on the basis of the Eysenck Personality Inventory (EPI). Five Ss from each group were randomly assigned to four paired-associate learning conditions (A-Br, A-C, C-B, C-D) and required to learn an A-B and a second paired-associate learning list to a criterion of one perfect score. Subjects were required to return to the lab after 24 hours for a retention test of both the second list and the original A-B …

Seasonal Nearshore Distributions Of Fishes In A Piedmont Section Of The James River, Virginia, Eugene George Maurakis

Master's Theses

The seasonal nearshore distributions of 17 species of fishes were determined in natural and artificially heated areas in a 9.6 km stretch of the Piedmont section of the James River, Virginia from July, 1973 to June, 1974. Analyses of the seasonal distributions were based on abundance and percent frequency of occurrence data. The maximum abundance and percent occurrence of ten of the 17 species of fishes in natural temperature areas occurred in early autumn. Deviations from this pattern included Notropis analostanus, equally abundant throughout the year, and Lepisosteus osseus, Notropis amoenus, Notropis ardens, Notropis rubellus, Catostomus commersoni and Lepomis macrochirus, …

The Modification By Temperature Of The Effects Of Mammalian Follicle Stimulating Hormone And 17b-Estradiol On The Process Of Vitellogenesis In The Lizard, Anolis Carolinensis, Susan Howard Early

Master's Theses

The effects of porcine follicle stimulating hormone, 17B-estradiol, and a combination of the two on the process of vitellogenesis were studied in Anolis carolinensis maintained at 15C with no light for one week, and then at 15C or 32C with 14 hours of light for two additional weeks.

At both temperatures, the control animals subjected to 14 hours of light possessed greater numbers of previtel­logenic follicles and lower liver weights than the control animals sacrificed after one week in the dark. Animals maintained at the higher temperature and given different hormonal treatments showed significant increases in ovary and oviduct weights, …

Anais Nin's Under A Glass Bell : From Interior Fatality To Psychological Motion, John Harty

Master's Theses

Most of the critic ism on Anais Nin has been an overview of her entire work. Under A Glass Bell is included but, to my knowledge, no one has explored each individual story deeply enough since Nin herself recommends Under A Glass Bell as the book to begin with when reading or studying her works. Ibelieve that her recommendation is correct because Under A Glass Bell contains the nucleus of themes which she conc entrates on in all of her works, including the Diaries.

The Relationship Between Gill Na+ + K+ -Activated Adenosine Triphosphatase Activity And Sodium Regulation In Acclimation Of The Blue Crab, John Lewis Harris

Master's Theses

Evidence from this study suggests that Na++K+-activated ATPase is involved in the ionic regulation of sodium in the hemo-lymph of the blue crab in low salinity environments. The time course of changes in gill Na++K+-ATPase specific activity follow- ing transfer of crabs from JO o/oo to 5 o/oo salinity indicates that a major increase in activity occurred within 2.5-3.0 hr. Apparently, a 8.8-11.1% decrease in hemolymph sodium ion concen-tration to about J55-J60 meq/1 in approximately 2-J hr was sufficient to activate the ATPase cation transport system in the gills of Callinectes sapidus. Following enzymatic activation, hemolymph sodium concentration gradually approached …

The Role Of An Eyestalk Extract In The Regulation Of The Blood Sodium And Calcium Concentrations Of The Blue Crab Callinectes Sapidus, Gregory Martin Ivy

Master's Theses

The effect of bilateral eyestalk ligation or ablation on the blood Na+ and ca++ concentrations of the euryhaline blue crab, Callinectes sapidus, was measured in 10 o/oo and 5 o/oo sea water. The ablations caused a significant decrease in the blood Na+ and ca++ over a 24 hour period. The serum Na+ level increased significantly 6 hours following injections of an eyestalk extract whereas the blood total ca++ level did not change significantly. Eyestalk ligation, however, did not cause significant blood Na+ and ca++ changes. The blood Na+ level of intact crabs increased significantly in acclimating to colder water when …

The Use Of Territory As A Natural Reinforcer In The Modification Of Academic Performance And Disruptive Classroom Behaviors, Sherwin Lynnwood Davis

Master's Theses

Emphasis is currently being placed upon the use of low-cost, naturally occurring reinforcers in classroom behavior modification programs. The effectiveness of students'territorial space as a natural reinforcer for social and academic classroom behaviors was investigated. Using the multiple baseline technique, student access to territorial space was systematically manipulated in an attempt to decelerate out-of-seat behaviors and to increase the percentage of assignments completed and graded either satisfactory or excellent. Student vocalization was also monitored; it was predicted that increases in desired academic behaviors would produce reciprocal decreases in vocalization. Finally, a fading procedure was utilized to remove gross territorial markings …

A Study Of The Symbol Of The Cross In Marcel Proust's A La Recherche Du Temps Perdu, Eugene Freedman

Master's Theses

Á la recherche du temps perdu, by Marcel Proust, is the story of a young, naive boy named Marcel who grew up to be a writer . In this paper, when the author of the novel is referred to, the name Proust will be employed, while the main character of the novel will be referred to as Marcel. For Marcel, the narrator of the work, the composition of a novel was his only hope for immortality and salvation from the passage of time, since time destroys. In his quest for immortality, it was his task to understand the ever-changing …

Master's Theses

A new scheme is presented for the preparation of 3~(4-chlorophenyl)-5,7-dichloro-l-methylnaphthalene, from which, four derivatives, 3~(4-chlorophenyl)-~-di(n-butyl)aminomethyl~5,7-dichloro-l-naphthalene-methanol hydrochloride, 3-(4-chlorophenyl)-5,7-dichloro-~-(2-piperidyl)-1-naphthalenemethanol acetate, l-[3-(4-chlorophenyl)-5,77dichloro-lnaphthyl]-3-di(n-butyl)aminopropanol hydrochloride, and 1-[3-(4-chlorophenyl)-5, 7-dichloro-l-naph,thyl]-2-(2-piperidyl) ethanol hydrochloride, were prepared. These four derivatives were submitted to Walter Reed Army Institute of Research for. the determination of their potential as antimalarial agents.

School Morale And Self-Esteem Involving Adolescents With Learning Disabilities, Ted E. Barrett

Master's Theses

A student's cognitive achievement may be facilitated or repressed by various elements that constitute his affective character; his feelings, attitudes, and expectations form a substantial relationship with achievement. Rather than limiting themselves to evaluating those cognitive areas that relate with various measures of achievement, the administrators and staff members at the New Community School (NCS) have specified a desire to investigate and measure both the attitudes toward school and the self held by their attending students. Within the domain of educational evaluation, greater significance is being accorded to the students' values, interests, and attitudes(Lockwood 1973). In keeping with such considerations, …
