Absolute Continuity and the Integration of Bounded Set Functions
The first chapter gives basic definitions and theorems concerning set functions and set function integrals. The lemmas and theorems are presented without proof in this chapter. The second chapter deals with absolute continuity and Lipschitz condition. Particular emphasis is placed on the properties of max and min integrals. The third chapter deals with approximating absolutely continuous functions with bounded functions. It also deals with the existence of the integrals composed of various combinations of bounded functions and finitely additive functions. The concluding theorem states if the integral of the product of a bounded function and a non-negative finitely additive function exists, then the integral of the product of the bounded function with an absolutely continuous function exists over any element in a field of subsets of a set U.

A Comparative Analysis of the Educational Theories of Charles Dickens and John Holt
The purpose of this study is to determine. whether Charles Dickens's educational theories in England during the nineteenth century are conclusively juxtaposed to John Holt's educational theories in America during the twentieth century. Chapter One introduces the proposition and states the general nature of the discussion in -subsequent chapters. Chapter Two presents a history of economic conditions in nineteenth-century England and shows how its evolution influenced Dickens's educational theories. Chapter Three discusses the economic conditions in twentieth-century America, the moral crisis- and its affect on youth, and Holt's theories of how children fail and how they learn. Chapter Four synthesizes Dickens's and Holt's -theories and establishes that their philosophies and aims in the field of education are closely juxtaposed.

United States Army Scouts: the Southwestern Experience, 1886-1890
In the post-Civil War Southwest, the United States Army utilized civilians and Indians as scouts. As the mainstay of the reconnaissance force, enlisted Indians excelled as trackers, guides, and fighters. General George Crook became the foremost advocate of this service. A little-known aspect of the era was the international controversy created by the activities of native trackers under the 1882 reciprocal hot pursuit agreement between Mexico and the United States. Providing valuable information on Army scouts are numerous government records which include the Annual Report of the Secretary of War from 1866 to 1896 and Foreign Relations of the United States for 1883 and 1886. Memoirs, biographies, and articles in regional and national historical journals supplement government documents.

The American Southern Demogogue and His Effect on Personal Associates
The nature of the American Southern demagogue, best exemplified by Huey Pierce Long, is examined. Four novels which are based on Long's life: Sun in Capricorn by Hamilton Basso, Number One by John Dos Passos, A Lion Is in the Streets by Adria Locke Langley and All the King's Men by Robert Penn Warren, are used to exemplify literary representations of Long. First the individual personalities of the four demagogue characters are described. Next, the relationships of female associates to the demagogues are examined, then the relationships of male associates to them. The first conclusion is that virtually all associates of a demagogue, whether male or female, are in some manner affected by him. A second conclusion is that All the King's Men provides the best study of a Long-like character; its hero, Willie Stark, may consequently live longer in history than the real Huey Pierce Long.

The Crystal and Molecular Structure of 2, 2' bipyridylglycinatochloro Copper (II) Dihydrate
The three-dimensional x-ray structure of 2,2'-bipyridylglycinatochloro copper(II) dihydrate has been fully refined to a final R factor of 0.081. The bipyridyl and glycine ligands are arranged about the central copper atom in a square planar configuration while the chlorine atom is 2.635 angstroms above this plane directly over the copper atom. This unusually long distance is explained by the positioning of a glycine group on the opposite side of the square plane, resulting in a distorted octahedral arrangement. Also, the chlorine atom is linked to three oxygen atoms via hydrogen bonding, thus stabilizing the distorted octahedral complex.

Tolerance to the Behavioral Effects of Methylphenidate
Thirty-one rats were trained on a differential reinforcement of low rate schedule. After responding had stabilized, animals were injected with methylphenidate, twice weekly, presession. Methylphenidate produced dose-dependent increases in response rates and decreases in reinforcements. Repetition of these doses produced a reduced drug effect, and a third administration of the 10 mg/kg dose further reduced the drug effect. Subsequently, the effects of daily and intermittent administration were determined for this dose. Daily methylphenidate, pre-session, produced tolerance to the behavioral effects of methylphenidate and cross-tolerance to the amphetamines. Twice-weekly methylphenidate, pre-session, produced partial tolerance to methylphenidate and partial cross-tolerance to the amphetamines. Thus, periodic exposure to the behaviorally disruptive effects of a drug of the amphetamine class reduces the effects of subsequent exposure.

Isozymes and In Vivo Activity of Triosephosphate Isomerase
The distribution of isozymes of triosephosphate isomerase was normal in all human tissues examined. This finding argues against the existence of tissue-specific isozymes. Normal distributions of isozymes were also found in patients with cri-du-chat syndrome. Thus it is unlikely that a gene for triosephosphate isomerase is located on the short arm of chromosome five in man. When triosephosphate isomerases from a wide range of species were examined by starch gel electrophoresis, definite evolutionary patterns were found. Kinetic studies were conducted on human triosephosphate isomerase under conditions simulating the intracellular environment of the erythrocyte. Calculations using the kinetic parameters obtained indicate that even in triosephosphate isomerase deficiency disease, enough enzyme activity remains that the rate of glycolysis should not become inhibited.

Civic Life-Styles in Dallas, Texas
Abstract: The civic life-styles typology of Charles Adrian and Oliver Williams was tested as to its theoretical utility in explaining empirical patterns of civic life-style items, and its comparability to other forms of urban behavior. The data are from a 1970 survey of 3,025 families by the City of Dallas, Texas. An exploratory factor analysis was done on civic life-style items. The factor index scores were used as dependent variables, and demographic and associational items were independent variables in a step-wise regression analysis. Only two of ten factors were found to be civic lifestyles; both were interpretable using the Adrian and Williams typology. Civic life-style behavior was found to be similar to other patterns of differential participation in urban structures.

A Critical Analysis of the Writings of Samuel P. Huntington on Political Stability and Violence
Samuel P. Huntington has argued that political stability is dependent on the degree of institutionalization of participation in the political system. Critical analysis of hypotheses reveals serious flaws in his logic. His concepts were shown to be very hard to make operational and to test. The main hypothesis of a direct relationship between institutionalization and stability was shown to be influenced most likely by additional intervening variables. This study seeks to survey and analyze some of the problems which have arisen with the present state of theory in comparative politics. However, this thesis is particularly interested in .Huntington's work which covers the evolution of his thinking regarding the relation of violence and of political stability, i.e., the degree of government and not the form, with the institutionalization of participation.

Children's Attitudes Toward Death
Most of the research relating to children and death has been psychological or psychoanalytic in nature and has employed case studies or projective methodology. This study utilized a sociological perspective and was aimed at discovering the socialization processes that shape children's attitudes in this area of inquiry. The children's attitudes were examined in terms of four variables, their definitions of death, the relationship of age and death, their reaction to self-destruction and the destruction of others, and the affects of the media on them. Findings from this study of twenty-five children provided further support for the contention that attitudes are the result of learning experiences, i.e., socialization, involving significant others. For the most part, the children's responses were reflections of dominant social values and might therefore be considered the result of socializing factors.

The Application of Group Contingent Reinforcement to Hospitalized Adolescents
Fifteen hospitalized adolescents were used as subjects. An individually consequated token economy was in effect during baseline. Measures were taken of work output, attending behavior, and disruptive behavior. During the treatment phase, reinforcement was contingent upon the performance of a randomly selected subgroup. Following the treatment phase, the individual token system was reinstated for baseline-2 measures. The mean performance of the group during baseline was compared to performance under treatment conditions for work output and attending behaviors. In addition, performance of the contingent subgroup was compared to performance of the non-contingent group. No significant t values were obtained. With failure to obtain significant t values, the null hypothesis was not rejected, i.e., the two conditions were not proven significantly different.

An Interpreter for the Basic Programming Language
In this thesis, the first chapter provides the general description of this interpreter. The second chapter contains a formal definition of the syntax of BASIC along with an introduction to the semantics. The third chapter contains the design of data structure. The fourth chapter contains the description of algorithms along with stages for testing the interpreter and the design of debug output. The stages and actions-are represented internally to the computer in tabular forms. For statement parsing working syntax equations are established. They serve as standards for the conversion of source statements into object pseudocodes. As the statement is parsed for legal form, pseudocodes for this statement are created. For pseudocode execution, pseudocodes are represented internally to the computer in tabular forms.

Studies Concerning Asparagine Metabolism in Lactobacillus plantarum
This study is concerned with the metabolism of L-asparagine in Lactobacillus plantarum (ATCC 8014). Theprimary area of investigation is the preliminary characterization of a previously unreported L-asparaginase enzyme in L. plantarum. This L-asparaginase was determined to be an inducible enzyme with variations in its activity level according to the L-asparagine level in the growth medium. L-Glutaminase could not be induced in this organism by L-glutamine, nor would L-glutamine induce the asparaginase activity. These and other studies with amino acid analogs demonstrated the high specificity of both induction and enzymic activity of the asparaginase. Various physical properties of the enzyme were studied. The enzyme was found to be inhibited by adenosine triphosphate (ATP). This inhibition appears to be cooperative in nature and of the type exhibited by allosteric enzymes. These studies should be confirmed on a highly purified enzyme as these preliminary experiments were performed using a crude cell-free extract.

A Comparison of Cloze Ability in Deficient and Non-Deficient Readers Matched According to Verbal Ability
The present study was designed to investigate whether a good reader, by the fifth grade, will have attained sufficient knowledge of the language structure to enable him to more exactly and more appropriately reconstruct mutilated texts than a poor reader, matched for verbal intelligence level. Four 250-word cloze-treated passages were administered to twelve deficient and twelve non-deficient sixth grade readers, matched according to sex and the verbal portion of the Wechsler Intelligence Scale for Children. Analyses of variance failed to show any significant differences between good and poor readers except for a weak indication that good readers produced more exact replacements.

A Content Analysis of Lexicons, Word Lists, and Basal Readers of the Elementary Grades: Their Relation to Art
In this investigation, a content analysis was made with eleven lexicographical sources and three basal reading series to determine if art and art-related words were present. The analysis was made with the use of two charts, in which each was divided into eight categories of word context. The Composite Chart contained 6,576 words found in six lexicons, five word lists and forty-two readers, and the Reader Chart contained 407 words found only in the readers. The analysis revealed: dominant categories and percentages, word and cumulative word frequencies, high and low frequency words, and the percentage of words found in the basal readers as compared to the lexicographical sources.

Some Basic Precursors of Learning Disabilities: The Maternal Deprivation Syndrome and the Failure-to-Thrive Syndrome
It is hypothesized in this study that children reared with "concerned" mothers (N) will display significantly superior intellectual performance and less neurological impairment as compared with children reared with neglectful mothers (MN) and children diagnosed as failure to thrive (FTT, falling below the third percentile in height and weight). The FTT children will show significantly more deficits than both N and MN groups. The participants in this study were forty-five children rigidly matched on all possible variables. F-tests and Newman-Keuls' analyses reveal severe intellectual deficits in both MN and FTT groups. The FTT group displayed significantly more neurological deficits lending support for a nutritional basis of this syndrome as opposed to the traditional psychogenic explanation.

Edgar Allan Poe's Journey and Abyss Motifs: Order vs. Disorder
The key to an understanding of what Poe attempted to accomplish with his art lies in his depictions of order and disorder in the universe. Poe's explorations of order and disorder revolve around journey and abyss motifs exemplified in his imaginative approaches toward nature, conscience, art, intuition, and apocalypse. These imaginative approaches serve to unify Poe's- work as a whole and emphasize his importance as a questing artist who not only sought to define the shape of reality in terms of stability and chaos but also sought to formulate a final metaphysical ordering of chaos and finitude.

The Self-Concept of the Hearing-Impaired Child
This study was an investigation of the relationship between the self-concepts of hearing-impaired children and the self-concepts of normal hearing children. Sixty-four hearing-impaired children and nineteen normal hearing children were given the Primary Self- Concept Inventory, the Piers-Harris Children's Self-Concept Scale, and were rated by a teacher using the Bristol Social Adjustment Guide. The differences between means were analyzed and tested for significance. It was concluded that there is no difference between the self concept of the hearing-impaired child and the self-concept of the normal hearing child. It was further concluded that the instruments currently available for measuring self-concept are poor and inadequate. Further research on the self-concept of the hearing impaired child was recommended.
