The Effect of Behavior Control Strategies Upon the Disruptive Student : A Case Study
No full textii, 40 leaves. Advisor: Richard Lampshire.The Problem. A fourth-grade student had disrupted
class, especially during specials, rather frequently. This case study was designed to determine if positive reinforcement and other techniques would decrease the frequency of
the problem.
Procedure. Meetings were held with staff. Data
was collected on a daily basis for more than nine months. Data including frequency and specification of reward and punishment was analyzed. Follow-up meetings were held.
Findings. Social reinforcement and extra privileges based on a reward system were found to be very effective. Activity curtailment and removal to a time-out room were also useful when the previous strategies were not successful. These programs must be very carefully structured

Single Parents' Preferences and Expectations for Home-School Communication
No full text281 leaves.
Advisor: Edward R. DucharmeThis study focuses on single parents' preferences and expectations for home-school communication in public schools. Home-school communication has received considerable attention from educators and parents in recent years.
Many see this communication as a vital link in establishing partnerships between educators and parents.Parents are the first teachers for most children and want the best for them. Parents have considerable influence on their children throughout the time they are in school. Studies show that parents want to know what is going on in school, how they can be a part of the school, and how they can assist their child at home. Parents prefer communication that is timely,understandable, and informal.Unfortunately, however, communication from the school
to home does not always meet these needs. Some parents believe that they are working in partnership with the schools. Single parents often believe they are left out of this partnership because of lack of time, economics, and
other issues which make it difficult for them to
communicate with educators. Educators cannot ignore these issues because the numbers of single parents and of students from single-parent homes have risen dramatically in the last two decades. Students from single-parent families now comprise almost one-third of all students. I conducted this study in several school districts inWestern Iowa. Interviews were used to determine single
rents' preferences and expectations for home-school communication. Many of these communications were initiated by the school. Some, however, were initiated by single parents. These contacts were also explored. Single parents had ample opportunities to share insights. The goal of the researcher was to look for themes and patterns in the lives at these parents, especially as th related to the school.
This study was done to gain a better understanding of situations facing single parents and their
expectations regarding communication with schools.
Several findings emerged from the research. One result is that educators should explore new means of communication with single-parent homes instead of assuming that present means are acceptable. Staff development is needed in order to accomplish this goal. I hope a result will be that students from single-parent homes will demonstrate higher levels of achievement
The Effects of Dimethyl Sulfoxide on the Mutagenic Action of Ethyl Methanesulfonate in Drosophila Melanogaster
No full text52 leaves.The problem. Ethyl methanesulfonate (EMS) is a potent alkylating agent, capable of inducing mutations in Drosophila at frequencies as great as 70%. EMS is often referred to as a radiomimetic substance because of the similarities between the clinical manifestations of radiation damage and injury due to alkylating agents. Dimethyl sulfoxide (DMSO) provides an effective protection against the mutagenic effects of radiation in many organisms including Drosophila. The major objective of this study was to determine the effects that topical application of DMSO would have on the mutagenic action of ingested EMS.
Procedure. Adult male Drosophila were treated in four ways. The five separate groups tested were treated with DMSO alone, EMS alone, DMSO followed by EMS, and EMS followed by DMSO. The fifth group was a control and received no treatment. Treated adult males were mated individually to three or four virgin Basc females. The Basc technique for detection of X-linked recessive lethal mutations was followed. Mutation frequencies were computed and subsequently submitted to chi square analysis.
Findings. The control group produced a mutation frequency of O.O%. This was used as a spontaneous X-linked recessive lethal mutation rate. The DMSO group demonstrated a 1.3% mutation rate. The EMS group produced a 35.9% mutation frequency. Pre-treatment with DMSO followed by EMS treatment resulted in a mutation rate of 31.6%. DMSO treatment following EMS treatment resulted in a 35.0% mutation frequency.
Conclusions. The data obtained from this study indicates that DMSO does not act as an antimutagenic substance against EMS in Drosophila. DMSO does appear to be slightly mutagenic after topical application and this application seems to reduce the overall reproductive capabilities of the treated males.
Recommendations. Further experimentation with various concentrations of DMSO and different methods of administration is necessary to fully elucidate the actual effects of DMSO in Drosophila
Lethal and Semilethal Mutation Frequency of the First and Second Chromosomes in Two Natural Populations of "Drosophila melanogaster"
No full textiii, 40 leaves. Advisor: Michael E. MyszewskiThe problem. The present study was undertaken to
examine potential genetic diversity as measured by the lethal gene frequencies between two natural populations of "Drosophila melanogaster".
High levels of trichloroethylene (TCE) and other
suspected mutagens and carcinogens, i.e., vinyl chloride, chloroform, etc., have reportedly been found in subsurface soil and waters near downtown Des Moines, Iowa. Lethal gene frequency of the first (X) and second chromosomes of the toxic population sample (captured within the toxic plume locale), was determined by genetic analysis and compared to that of a "control" population sample captured in an area believed to be free of chemical contamination.
Procedure. The Basc technique for determining
X-linked lethal mutation frequency and the Cy/Pm method for determining second chromosome lethal mutation frequency were employed. Mutation frequencies were calculated and data was analyzed by the Chi-square method.
Findings. The X-linked lethal mutation frequency of the control population sample was found to be 0%. Compared with the toxic population X-linked lethal mutation frequency of 1.47%, the difference is not significant. Drastic (lethal + semilethal) mutation frequency of the control population second chromosomes was found to be 48%. When compared to the toxic population second chromosome drastic mutation frequency of 56%, the difference is not significant.
Conclusion. The data obtained from this study showed that the chemical contamination of the toxic population sample habitat had no significant effect on the frequency of X-linked or second chromosome lethal mutation
Mountain Man : Fact and Fiction
No full text155 leaves. Advisor: Dr. Norman R. HaneThe problem. The purpose of this dissertation is to examine representative factual and fictional accounts of the mountain man, a pioneer to the Rockies in the early and mid-nineteenth century. Certain components are examined and weighed against each other in an attempt to ascertain the authentic image of the mountain man.
Procedure. Initially the historical mountain man is examined: his motives, his attitudes, his skills, his habits, his relations with the Indians. Next, the disagreement between William Goetzmann ("The Mountain Man as Jacksonian Man") and Harvey Lewis Carter and Marcia Carpenter Spencer ("Stereotypes of the Mountain Man") -is explored, and each image illustrated by examples from both history and fiction. Finally, through analysis of journals, accounts of travelers to the frontier, novels, poetry, and film, the
building of this sometime roughneck into an alltime hero is demonstrated. Extensive study is given to Hugh Glass, one of the first mountain men, and to John Johnston, one of the
last. The major sources dealing with Hugh Glass are Pirate, Pawnee and Mountain Man by John Myers Myers, The Song of Hugh Glass by John G. Neihardt, and Lord Grizzly by Frederick Manfred. Those dealing with John Johnston are Crow Killer: The saga of Liver-eating Johnson by Raymond W. Thorp and Robert
Bunker, Mountain Man by Vardis Fisher, and Jeremiah Johnson, a film directed by Sydney Pollack.
Conclusions. In the brief career of the mountain man (1822-1850) America found a culture hero. He was a loner and a wanderer, symbolizing the frontier spirit and American freedom. His thoroughness in trapping nearly exterminated his prey, the beaver. His expeditions led him deep into the Rocky Mountains where he discovered the mountain passes and river routes that would make possible western emigration. These two conditions signaled the end of his days in the
Rockies and showed him to be the unwitting agent of his own demise. He left little written record. One must therefore turn
to the journals of company men, accounts of travelers to the western frontier, and later research. Four images occur separately and in combination: the Jacksonian man engaging
in economic exploitation of the wilderness, the daring degenerate illustrating the effect of Frederick Jackson Turner's "corrosive influences" of the frontier, the explorer probing the Rockies, and the romantic hero moving away from the corruption of civilization to experience a oneness
with Nature. Rather than being a new type in American literature, he is an extension of the frontier hero seen in Davy Crockett and in Cooper's Leatherstocking. His life and habits are refined to suit public taste, and he emerges the romantic hero who is, most of all, free
Job Motivation Factors as Perceived by Teachers and Nurses
No full textv, 45 leaves. Advisor: Richard Lampshire.The problem. The two-factor theory of motivation to work developed by Frederick Herzberg provided the conceptual framework for this study. The general purposes of the study were to discover whether nurses and teachers perceived either motivation or hygiene factors to be greater
motivators, whether those job factors were present in their jobs, whether there was a difference between the job factors desired by nurses and the factors desired by teachers, and whether there was a difference in the degree to which nursing and education provide the needed job factors.
Procedure. Thirty-nine teachers and thirty-one nurses returned a questionnaire which indicated the degrees to which they perceived themselves as motivated by sixteen job factors and the degree to which the factors were present in their jobs. Means were computed for motivation factors needed, motivation factors present, hygiene factors
needed, hygiene factors present, and means were
tested by separate variance model t test for significant differences (a.O5) between means.
Conclusions. It was found that neither teachers nor nurses perceived a greater need for either motivation or for hygiene factors. Neither group felt that one set of job factors was present in their jobs to a greater degree than the other set. Nurses felt, however, that their jobs provided
motivation and hygiene factors to a greater degree
than teachers felt their jobs provided them. Both groups felt that they needed motivation and hygiene factors to a greater degree than those factors were present in their jobs
The Role of Herbert Hoover in the Formulation of the American Response to the Far Eastern Crisis of 1931-1932
No full text123 leaves. Advisor: Frederick AdamsThe problem. The problem concerns the extent to
which Herbert Hoover formulated the American response to the Far Eastern Crisis of 1931-1932, since most historians credit Secretary of State Henry L. Stimson for the major contributions and dismiss Hoover as too preoccupied with the domestic financial crisis to do more than agree to
Stimson's actions.
Procedure. The procedure has been to utilize primary sources available, such as the Stimson Diary, Foreign Relations of the United States, Documents on British Foreign Policy, materials at the Herbert Hoover Presidential Library and secondary accounts in determining Hoover's involvement, both in time spent and actions taken.
Findings. It has been found that although the greater part of Hoover's time was spent on domestic problems, he was fully knowledgeable of events, he set the parameters of the American response, and contributed several suggestions,
including the nonrecognition policy.
Conclusions. Hoover was the final authority on
policy. His main concerns were to retain order in the Orient for American business interests to prosper, to show moral outrage at Japanese aggression, and to avoid direct confrontation with Japan. Stimson executed these policies.
Although war was avoided in 1932, the policies formulated in this period failed to stop Japanese aggression
