Engineering Solutions To Recycling Problems, O. N. Carlson

Proceedings of the Iowa Academy of Science

There are a large number of serious environmental problems that have received an increasing amount of attention in recent years. Most of them are by-products of our complex technological society and stem directly from our rising standard of living and unprecedented population growth. Their solutions are equally complex and will require a combination of scientific understanding, engineering ingenuity, economic sagacity and political courage. It would be impossible to cover all of these problems in a short time. Therefore, consistent with my interest in process metallurgy, these remarks are limited to the optimization of our dwindling mineral resources with emphasis on …

A Slide-Tape Introduction To A Unit On The American Indian, Linda L. Jones

Graduate Research Papers

In order to develop a curriculum which is more relevant to student interests and the school's needs, the librarian and teacher have certain duties to perform. The teacher defines the objectives desired; the librarian provides and develops media which achieve these bjectives. Therefore, the librarian and the Instructional Media Center are the best sources not only for commercially produced materials hut for those which the school produces. Possibly the most effective area to produce materials would be in units not covered adequately by the textbook, in this case, the American Indian.

Critical Analysis Of Mother Goose, Jeanne Opperman

Graduate Research Papers

Nursery rhymes have been considered trifles until comparatively recent times and consequently were never taken too seriously. It has only been with the increased interest in the science of folk-lore that they have begun to attract attention and their true purpose and meaning discovered.

My curiosity about the origin of Mother Goose rhymes · came through a course taken in children's literature. I wrote a paper at that time on some of my findings and observations. This paper is an enlargement and updating of that project including more information from historical sources, a study of selected foreign editions and some …

A Preliminary Stratigraphic Study Of The Galena Group Of Winneshiek County, Iowa, C. O. Levorson, A. J. Gerk

Proceedings of the Iowa Academy of Science

The rocks of the Galena Group have proved to be problematic in correlation. This problem is due to a variable lithofacies development. A preliminary investigation, although based upon exposures studied just within Winneshiek County, provides a method for field identification in Iowa of stratigraphic units currently used by the Illinois State Geological Survey within Illinois. Units under consideration at this time are restricted to the Dunleith, Wise Lake, and Dubuque Formations. Methods of identification and correlation employ in part such physical features as sequences of nodular chart bands, discontinuity surfaces, and sparry calcarenite bands. Investigation has disclosed a close relationship …

Engineering Solutions To Environmental Problems, Richard B. Miller

Proceedings of the Iowa Academy of Science

The environmental problems that we face today are largely associated with what we call the "good life." The "good life" consists of lots of leisure time, low cost of goods, lots of modem conveniences, etc. This means the convenience of prepackaged foods, throw-away containers, and all kinds of disposables. The free time gives us lots of time to travel, recreation, etc. We're able to afford it because we have mass production made possible primarily by electrical energy. We like to travel so we need lots of transportation: automobiles, airplanes, etc. Our income has gone up faster than our costs, and …

Effects Of Ddt On The Density And Diversity Of Tardigrades, Gary W. Barrett, Ronald G. Kimmel

Proceedings of the Iowa Academy of Science

Twenty lichen-bearing tree bark samples were collected from DDT sprayed American elm trees (Ulmus Americana L.) in central Iowa. Twenty comparable samples were collected from an adjacent nontreated habitat. A tardigrade density of 4 individuals collected from the treated habitat was found to differ significantly (P < .01) from a density of 97 individuals collected from the non-treated area. Margalef's diversity index (D=S-1/1n N) determinations were found to be 0.00 and 0.44 for the treated and non-treated habitats, respectively. Tardigrade species organization within the nontreated habitat did not differ significantly from that as predicted by MacArthur's broken-stick model, suggesting that tardigrade species occupy contiguous, non-overlapping niches within a …

Some Diatoms In Lacustrine Sediments Of Pillsbury And Sylvan Lake Beds In Northwest Iowa, James J. Hungerford

Proceedings of the Iowa Academy of Science

Diatom populations in two cores of lake sediments from Northwest Iowa have been analyzed as part of an investigation into the history of postglacial sediments in this region. The three member strata sequence of sediments indicate lacustrine diatoms were deposited in the upper two members. Diatoms and macroscopic organisms are scarce to non-existent in the deepest member. Evidence indicates that the level where diatom populations were first established represents the original bottom of the lake. Pollens, particularly spruce pollen, found immediately below the upper two members were possibly blown in and mixed with sediments from the receding glacier.

A Study Of Cross-Cultural Groups At Malcolm Price Laboratory School; University Of Northern Iowa, Leander A. Brown, Richard F. Strub, Shirlee Rainey

Faculty Publications

A brief history of the integration efforts of the school and the resulting interracial conflict is presented. From this background evolved the cross-cultural groups which are the focus of this paper. Essentially; discussion was used for exploring the issues which were identified as impediments to good relationships within the school; (1) too few black faculty and students; (2) the impact of "Tomism;" (3) geographic location of students' homes; (4) differing interests of black and white students; (5) the need for extra-school interracial contact; and (6) inhibitions; both social and parental; against interracial contact; especially dating. The results of a questionnaire; …

A Study On How The Male And Female Are Portrayed In Children’S Literature, Diane Jean Reed

Graduate Research Papers

To the majority of Americans, women's liberation is a common term among most circles. Just recently another group is capturing the headlines and will be gaining more support with this publicity. This group has coined the name "Feminists on children's Media." Their attacks are becoming greater as more parents, librarians, and concerned citizens become actively involved in the way women and men are stereotyped in both juvenile literature and school textbooks. Previously, critics had concentrated on the intermediate level of reading, while now, more are becoming interested in picture books and beginning readers.

The Fighting Word Doctrine From Chaplinsky To Brown, Franklyn S. Haiman

Iowa Journal of Communication

On April 11, 1971, nineteen-year old Robert Vitek of Shaker Heights, Ohio, was stopped and ticketed for speeding by University Heights Police Sergeant Jay McKenna. While the officer was filling out his ticket, Vitek called McKenna a "pig." Judge Manuel Rocker of the Shaker Heights Municipal Court later found Vitek guilty of abusing a police officer, fined him $100, and sentenced him to spend three hours in a pigsty so that he might learn to "distinguish the difference between a pig and a police officer."¹ Since the young man in question apparently was not discontented with his sentence, this …

The Video Tape Recorder, Television And The High School Media Specialist, Margaret Kay White

Graduate Research Papers

An important part of using TV to teach centers around the use of the video tape recorder. A basic videotape recording unit consists of a videotape recorder, a playback monitor, a television camera and a microphone.

Integral to any discussion of the VTR is an investigation of the different aspects of using television for educational purposes. The first step in this paper, therefore, will be a careful exploration of the advantages and disadvantages of television and, indirectly, videotaping, in secondary education.

Without careful planning the VTR can become just another piece of mechanical equipment lost in the closet of a …

The purposes and procedures to be used were explained to them and they then indicated whether …

Stilicho: The Man And His Times, David Bliss Hanawalt

Dissertations and Theses @ UNI

The purpose of this thesis, Stilicho: The Man and His Times, is to study a period of the history of the Roman Empire through the life of Count Stilicho. The purpose is also to appraise the career of this barbarian Roman general in order to give what I think is a fairer evaluation of the man than has been presented by former historians. Stilicho was stigmatized by the historian Eunapius (fl. 400), and though some historians have commented favorably about Stilicho, few have attempted to assess his importance in Roman history. I have treated major interpretations of Stilicho 1 s …

How Do You Tell The Good Guys From The Bad Guys, Ruth J. Laws

Iowa Journal of Communication

The cover of the November 1968 issue of Psychology Today illustrates a political candidate standing on the rear platform of a whistle-stop train. The scene appears to depict a dilemma in the political arena today. On the candidate's right is a mother lifting her baby for the politician to kiss; on his left a television camera is held up to him. Actually the contemporary candidate is faced with no conflict of decision. He swiftly moves to plant his image on the video camera.

This situation makes it apparent that the popularity of television has done more than reduce the ticket …

Bacteriological Quality Of Lake Red Rock And The Des Moines River Between Des Moines, Iowa, And Lake Red Rock, Dean A. Hoganson, Stephen C. Elliott

Proceedings of the Iowa Academy of Science

The bacteriological quality of the Des Moines River from Des Moines, Iowa, to Lake Red Rock and the lake itself were studied on eleven sampling dates from July 1969 to May 1970. The examined river sites consistently had higher EMB plate counts than sites in the lake proper and counts from both river and lake were generally far above quoted standards of water to be used for contact and non-contact water sports. The pH readings were all within quoted normal ranges. The expected effects of seasonal variation and runoff on bacteriological counts were found. Seven isolations of pathogenic, enteric bacteria …

The Effect Of Preschool Experiences On The Achievement Of Kindergarten Children Enrolled In The 1971-1972 Follow Through Program In Waterloo, Iowa, David Phillip Stetson

Dissertations and Theses @ UNI

The problem of the investigation concerned itself with the effect of preschool experiences on the achievement of the kindergarten children enrolled in the 1971-1972 Follow Through Program in Waterloo, Iowa, which used the Pittsburgh, Pennsylvania, model of individually prescribed instruction. The study explored the effects of preschool experience upon kindergarten males and females as contrasted to the male and female kindergarten children without preschool experience.

Two conceptual constructs gave direction and provided the rationale for this study. The first conceptual construct provided research related to early childhood education presented according to the Geneticist, Environmentalist, and the Interactionalist's positions. The second …

The Role Of The School Psychologist As Perceived By Elementary Principals And By School Psychologists, Joan Holliday Smith

Dissertations and Theses @ UNI

The problem that was considered in the study was whether the role of the school psychologist was perceived differently by elementary principals and school psychologists.

A questionnaire was developed which had two slightly differing forms, one for principals and one for psychologists. The items on the questionnaire sought to assess the opinions of both groups concerning: who is and who should be responsible for selected tasks, the effectiveness of psychological services and several aspects of authority. The questionnaires were sent to a randomly selected group of elementary principals (200) and all of the school psychologists in Iowa (170). Useable returns …

An Analysis Of Data And Records Of Two Selected Groups Of Students In The Context Of The Admissions Program At The University Of Northern Iowa, Jack Lloyd Wielenga

Dissertations and Theses @ UNI

This study was undertaken to compare the level of academic success of two groups of students as they were affected by admission policies and practices at the University of Northern Iowa. Students in both groups ranked in the lower half of their respective graduating classes. Students in Group I were denied admission, and students in Group II were admitted to the fall semester 1964.

High school counselors and college registrars at 232 schools were asked to provide transcripts of records and/or completed reporting forms for each of the 185 students in Group 1 who had previously attended their institutions. This …

The Development Of A Nutrition Education Game For The Expanded Nutrition Program In Black Hawk County, Iowa, Linda Foster Benedict

Dissertations and Theses @ UNI

The problem of the study was the lack of entertaining and effective ways to teach nutrition in the youth phase of the Expanded Nutrition Program in Black Hawk County, Iowa. The question of the study was can a game be developed which will teach the participants in the youth phase certain nutritional concepts and be appealing to the youth. The author developed a game for the population in the study which was effective in teaching certain cognitive information about nutrition and appeared to be appealing to them. The development of the game included three main steps--review of commercial games, designing …

Proposed Guidelines For An Iowa Local High School Chapter Of The Distributive Education Clubs Of America, Weldon Else

Dissertations and Theses @ UNI

It was the purpose of this study to secure, analyze, and present information that may be used by distributive education advisors to improve total chapter achievements. Since distributive education teacher-coordinators possess such information, this study sought to determine by means of questionnaires (1) the procedures and techniques used by local chapters of DECA, and (2) the opinions of local teacher-coordinators concerning DECA activities and recommendations for change based on their own experiences.

Video Tape Versus Live Demonstration In Yeast Bread Preparation, Ruth Martin Fisher

Dissertations and Theses @ UNI

The primary purpose of the study was to determine whether video tape demonstrations can be used effectively in teaching basic yeast bread knowledge and laboratory preparation activities that require accuracy and skill in obtaining a standard yeast bread product. The population of the study consisted of thirty-eight Home Economics II students in the Cedar Falls High School. Two classes, comparable in intelligence quotient range, mean, and standard deviation, were selected to serve as the experimental and control groups for the study. The experimental group was composed of eighteen students and the control group was composed of twenty-four students. Yeast bread …

Selected Choral Literature For The High School Chamber Choir: With Specific Reference To The Style And Performance Practice Of Renaissance Choral Music, Alan J. Hagen

Dissertations and Theses @ UNI

The decade of the 1960's witnessed a growing interest in choral chamber music. This became increasingly apparent in clinics and conventions across the country which devoted considerable attention to chamber choir literature, style , and performance practice. This trend was further manifested through informative articles, which appeared in music periodicals with growing regularity late in the decade, concerning the chamber choir and inherent problems. Choral chamber music took on added significance in Iowa in 1968 when the Iowa High School Music Association introduced chamber choir competition into the state music contest series. This action prompted numerous questions regarding the definition …

El Tiempo En La PoesíA De Machado, Mario O. Curbelo

Dissertations and Theses @ UNI

This study proposes to demonstrate that time is the general emotional basis for the lyric poetry of Antonio Machado, and to point out the human quality with which it is expressed in his verses. First we examined his poetic theory to determine how the sense of time is set forth in the composition of the poem, and noted the one specific example he offers as a demonstration of said theory. Then we went on to observe in many of his verses that he indeed follow the precept he laid down in prose, and through the analysis of these poems we …
