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.

The purpose of this study was to determine significant differences in test scores between LLD and MBI Special Education students. The records of thirty-seven LLD and fifty-six MBI students between the ages of six through eleven were obtained from a small Texas school district. The results indicated no significant differences between groups on WISC Full Scale, Performance and Verbal scales or on WISC subtests scores. No significant differences were found on WRAT scores. Significant differences were found on the Bender-Gestalt Test for Children and the Visual Aural Digit Span Test at the nine- through eleven-year level. No differences were found at the six- through eight-year level.

This study investigated the relationships between locus of control and perceived contingency of parental rewards and punishments. Questionnaires measuring subjects' locus of control and their perception of parental contingency behavior were administered to undergraduate college students. The obtained measures of contingency of parental rewards and punishments were correlated with scores on Rotter's I-E Scale. Of the maternal contingency factors, only noncontingent punishment related significantly and negatively to internality (males only). Paternal contingent punishment related positively and significantly to internality for both males and females. There was a significant negative relationship between paternal noncontingent punishment and internality (males only). None of the parental reward factors related significantly to locus of control.

This study examines interrelationships between Chinese students' associations with each other, with American friends, and their identification with American society. Fifty-three randomly-selected Chinese students at North Texas State University were interviewed in May, 1974. The resulting data was tested by Chi-square and Gamma tests. The finding are an follows In the United States, Chinese students are in a dynamic adjustment process. In their early stay, Chinese students with high scores of a affiliation with Americans have low scores of identification with American society. However, affiliation with other Chinese brings satisfaction and further identification. Therefore, Chinese students with high scores of affiliation with each other have high scores of identification with Americans.

This study explores the relationship of Royall Tyler's The Contrast with Richard Brinsley Sheridan's The School for Scandal, to determine whether Tyler used The School for Scandal as a model for The Contrast. Chapter I contains a statement of the problem and an introduction to the historical importance of Tyler and The Contrast. Chapter II discusses the theatrical background of Tyler and the city of Boston. Chapter III includes a brief history of Sheridan and an examination of The School for Scandal. Chapter IV compares The Contrast with The School for Scandal. Chapter V presents conclusions drawn from the evidence examined in Chapters III and IV. The Contrast is not an imitation of The School for Scandal, though both contain elements of similarity.

The purpose of this study was to identify certain aspects related to sight singing which tend to cause difficulty in teaching junior high school students and to suggest exercises that might be used to aid in overcoming these difficulties, Data included a questionnaire to junior high school teachers in three states. Subjects researched and discussed were the physical, intellectual, and emotional development of the adolescent; the changing voice and the range and vocal limitations of junior high singers; and rhythmic, melodic, harmonic, and other aspects of sight singing. Included were vocal procedures to be used with young voices, suggestions for choosing and/or arranging appropriate music, and original compositions designed to meet the needs and interests of junior high school students.

This study examines ultrastructural changes occurring in seven- and fourteen-day populations of Trypanosorfa lewisi when 60 mg sodium salicylate is administered to the host. These changes were related to the host-immune response. Seven-day trypanosomes showed approximately 10 posterior volutin granules. Seven-day trypanosomes whose host had received salicylate exhibited. 30 to 40 volutin granules, and their posterior tip exhibited volutin granules in high numbers sometimes excluding other cellular elements. Fourteen-day trypanosones showed fewer volutin granules than seven-day, salicylate-treated ones. Salicylate treatment caused no additional ultrastructural alterations. Thus the volutin granules are not linked to the reproduction inhibiting antibody (ablast in) but may be involved in the formation of the trypanocidal antibodies.

This study investigates how television coverage of the 1968 Democratic National Convention largely determined the negative public impression of the convention and its candidate. The coverage had a definite effect on the workings of the convention through the images and information it conveyed to the delegates. The coverage also shaped the broadcast picture of the event by linking the convention to the violence in the streets.

This working bibliography of 835 publications on the art of drawing is presented in five categories: Educational and Psychological, Historical, "How-to," Technical, and Techniques of Teaching Drawing. The latter category is annotated, offering a synthesis of the areas of art education and drawing. This bibliography is designed for scholars, artists, and teachers as well as students of the many facets of drawing.

The purpose was to verify ego states as objectively identifiable phenomena and the influence of early parent-child relationships on their identification using an audio tape of recorded examples of ego states, Thompson's Ego State Tape (EST), and the Roe-Siegleman Parent-Child Relations Questionaire (PCR). No relationship was found between SAT scores and scores on the EST, nor between PCR and EST scores. It was concluded that possibly (1) no relationship existed between how children perceive their parents and the identification of ego states, and (2) that the PCR might not be sampling child rearing practices relevant to the identification of ego states.

The problem with which this investigation was concerned was the comparison of cedar elm populations in different stands along creeks in Denton County, Texas, and the relationship of certain population parameters to various substrates present at stand sites, Parameters investigated eluded average basal area, basal-area density, transect-segment density, intertree distance, lateral distance, frequency, diameter breast-high, diameter breast-high size-class distribution, and immature-tree density. Variations among populations of Ulmus crassifolia Nutt were noted and analyzed in terms of soil particle size and existing community conditions.

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.

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.

The purpose of this thesis is to determine the limits of evidence concerning the biography of the Roman poet Catullus, the texts of his poems, and the earlier poetic influence on his longer works and to compare scholarly opinions about those topics. To attain those objectives, both classical authors and modern scholars were used as sources. This work has five chapters. The first outlines the problems of Catullan scholia. The second and third discuss his life and texts. The fourth and fifth concern Catullus' poetic creed and his borrowings from earlier poets and poetic traditions. This paper's conclusion is that, although no full assessment of the poet can be made without additional evidence, Catullus remains a major poetic figure deserving of additional study.

Internal-external locus of control was studied in relationship to the religious phenomena "glossolalia." Contrary to the main hypothesis formulated, glossolalics were found significantly more internal in locus of control than non-tongues speakers. Intercorrelations were studied between the variables of I-E, age, length of church membership, income level, educational level, and perceived control by God, for tongue-speaker and non-tongue-speaker groups. Chisquare comparisons were made between the groups on educational level, income level, and perceived control by God, with significant differences being found in educational level. Additional analysis was made between I-E and the variables of educational levels, income levels, and perceived control by God. Historical and current interpretations of the personality of glossolalics are challenged. The construct validity of the Rotter scale for use with religious populations is challenged.

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.

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.

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.

This study tests whether positive reinforcement consisting of a positive word, eye contact, and a smile would improve the self-concept of students. Sixty boys and girls in two sixth-grade classes were given an adaptation of Gordon's, How I See Myself scale. A baseline consisting of positive reinforcements given by the teacher to the students was taken. Then a positive reinforcement schedule was instituted by the sixth-grade teacher. The experimental group of thirty students received a mean of 24.78 positive reinforcements per class; the control group received a mean of 1.1 positive reinforcements. The subjects were again given the HISM scale, and no significant score differences were found between the experimental group and control group.

Inverse systems, inverse limit spaces, and bonding maps are defined. An investigation of the properties that an inverse limit space inherits, depending on the conditions placed on the factor spaces and bonding maps is made. Conditions necessary to ensure that the inverse limit space is compact, connected, locally connected, and semi-locally connected are examined. A mapping from one inverse system to another is defined and the nature of the function between the respective inverse limits, induced by this mapping, is investigated. Certain restrictions guarantee that the induced function is continuous, onto, monotone, periodic, or open. It is also shown that any compact metric space is the continuous image of the cantor set. Finally, any compact Hausdorff space is characterized as the inverse limit of an inverse system of polyhedra.

The purpose of this study is to set forth the history of radio in Nigeria. Chapters explore the history of Nigeria, the history of Nigerian radio, and the present structure of Nigerian radio. In a final chapter, specific historical factors are isolated that have made Nigerian radio what it is today. The study concludes that the present structure of Nigerian radio is a direct product of the peculiar history of Nigeria as a former British Colony. Little can be done to solve the problems of Nigerian radio unless the problems of Nigeria itself are first solved.

This study was a simple "before" and "after" attitude measurement experiment using an experimental group and a control group. The attitude measurements were made before and after the subjects in the experimental group were presented an informational briefing about the Air Force ROTC training program. Both the experimental group and the control group were subject to exposure to the Air Force mass communication advertising during the two-month study period. The results indicate that the increased knowledge gained by the experimental group through its exposure to the informational briefing caused a negative change of attitude within the group. However, the control group had no significant change of attitude during the study period even though more than 87 percent of those subjects were exposed to some form of Air Force advertising.

The life history and ecology of Neochoroterpes mexicanus was studied from data collected September, 1971, to August, 1972, and January to December, 1973, in the Brazos River, Texas. Nymphal development, instar analysis, voltinism, standing crops, and production estimates were determined from the quantitative samples taken in 1971 and 1972. Aspects of the life history and food habits of 230 specimens were arrived at from qualitative samples and light box captures in 1973. Laboratory investigation in 1973 helped in establishing instar analysis, egg incubation and description, and first instar descriptions. Neochoroterpes mexicanus appeared to have three generations per year with brood overlap in the summer and fall. It displayed 16 and 19 instars for overwintering and combined summer generations respectively.

This examination of the most popular plays of Rodolfo Usigli, Salvador Novo, and Emilio Carballido shows their concern with Mexico's social problems--especially as evidenced by their representation of contemporary social classes through characterization. Treating socio-political and sexual problems with special emphasis upon psychology, Usigli combines melodramatic reality and imagination. Psychoanalysis is also important in Novo's characterizations; his themes and characters express a social criticism which often becomes a malicious satire of Mexican life. Carballido's symbolic surrealism creates an atmosphere of fantasy, with scenic neo-realism representing everyday life, bourgeois ideas, and the Mexican psychology.
