Effect of Light and Other Environmental Factors on Growth and Carotenogenesis of Corynebacterium Species Strain 7E1C (open access)

Effect of Light and Other Environmental Factors on Growth and Carotenogenesis of Corynebacterium Species Strain 7E1C

This investigation studies effects of environmental factors on growth and carotenogenesis in Corynebacterium strain 7ElC. Changes in pH were found to effect growth more than carotenogenesis. However, certain nutrients or long incubation periods stimulated carotenoid formation more than growth. Dark conditions in a mineral salts-glucose medium stimulated growth, but minimized carotenogenesis. Tryptic soy broth or yeast extract elicited carotenogenesis in darkness. Although brief light exposure during inoculation was photoinductive, continuous exposure to light following inoculation was required for maximum pigment synthesis. Dark grown stationary phase cells required 24-hours of light for maximum pigment synthesis. Chloramphenicol inhibition of carotenogenesis in dark grown cells exposed to light showed that enzymes needed for carotenoid synthesis were absent from dark grown cultures.

A Study of Press Freedom in South Africa (open access)

A Study of Press Freedom in South Africa

The problem of the study was to analyze conditions of the South African press, including effects of apartheid legislation on the free flow of information. The method of research was mail questionnaire to editors of twenty-two South African daily newspapers. The study showed that the South African press is restricted by legislation and additional laws are expected. Other information from the study includes the following: at least four main laws impede the free flow of information; the press has ready access to government officials; Die Burger and The Star are considered the most influential newspapers; and Prime Minister Vorster's recent advice that the press "put your house in order" seems aimed largely at key English-language newspapers.

The Treatment of the Heroines in Representative Novels of François Mauriac (open access)

The Treatment of the Heroines in Representative Novels of François Mauriac

This study analyzes specific scenes in the novels dealt with in order to determine the type of women characters Mauriac has created. This study covers Mauriac's early, middle, and late periods as a novelist. The heroines are nearly all examined in relation to each other chronologically. The study shows that Mauriac first portrays a religious and simple heroine. The heroines become agnostic, if not atheistic in several of the subsequent novels. Through Therese, they become progressively more psychologically complex. They then become less complicated and, except for the last heroine, are religious. The last heroine is psychologically portrayed but is the least original of the heroines. The examination of Mauriac's women characters seems to show that the author is deeply sympathetic with the majority of them.

The Relationship of Selected Variables, Including a Course of Study, to Attitude Change of School Bus Drivers (open access)

The Relationship of Selected Variables, Including a Course of Study, to Attitude Change of School Bus Drivers

The effect of selected driver and instructional variables on attitude change of school bus drivers was examined. A total of 113 male and 69 female in-service Texas school bus drivers participated. The course of instruction, totaling 20 classroom hours, consisted of 11 units related to driving efficiency. Driver attitude was measured by a multiple-choice check list, administered prior to and following the course of instruction. A significant positive change occurred in those variables related to driver age, educational attainment, and number of classroom participants. Those variables involving course participation status and sex difference resulted in no significant positive attitude change. These findings may prove helpful in designing training programs for school bus drivers.

An Application of Small-Group Methods to Judicial Decision Making by the Nixon Court (open access)

An Application of Small-Group Methods to Judicial Decision Making by the Nixon Court

This study isolates the impact of certain factors upon the decision making of the United States Supreme Court. Selected group theory methodology is applied to the Court's decisions from 1969 through 1973. The group structure of the Court, the impact of personnel change, and the effect of judicial attitudes on public policy are explored and statistically measured with a chisquare. Schubert's bloc analysis and a Guttman scale are used to order the data. Conclusions include that two stable blocs existed on the Court during these years. Personnel change is demonstrated as causative of alterations in judicial behavior. Seven of eight groups of cases are shown to stimulate values of the Justices. Suggestions are made for further research.

Energy and Archetype: A Jungian Analysis of The Four Zoas by William Blake (open access)

Energy and Archetype: A Jungian Analysis of The Four Zoas by William Blake

The purpose of this study is to examine the parallels between the tenets of Carl Jung's psychology and the mythopoeic structure of Blake's poem, The Four Zoas. The investigation is divided into three chapters. The first deals with the major conceptual parallels between the intellectual systems of the two men. The second is a detailed analysis of the poem, and the third concludes the study by discussing the originality of Blake's thought. Blake anticipated much of Jung's psychology. The parallels between the two are so strong that each man seems to corroborate and validate the opinions and insights of the other. The extent to which he foreshadows Jung reveals Blake to be one of the most original thinkers of any period of time.

Religion and Fantasy in Selected Novels of Ramon J. Sender (open access)

Religion and Fantasy in Selected Novels of Ramon J. Sender

This study is an assessment of the topics of religion and fantasy in several novels of Ram6n Sender which various critics have characterized as being particularly concerned with one or both of the topics. Both published and unpublished works of criticism and history have been, consulted. The "Introduction" provides biographical and critical information. Chapter II documents in the characterization and the observations and actions of characters significant reflections of the author's attitude toward religion. In Chapter III the primary emphasis is upon the illogical, the absurd, and the grotesque, The "Conclusion" states that in the opinion of critics, in the significance of characterization, and by his own admission, Sender is liberal, anticlerical, humanistic, and occasionally attracted to the fantastic.

Visuo-Spatial Abilities and Reading Achievement in First- and Fifth-Grade Children (open access)

Visuo-Spatial Abilities and Reading Achievement in First- and Fifth-Grade Children

This study attempted to clarify the relationship between visuo-spatial abilities and reading achievement at the first and fifth grades. Groups of good and poor readers were selected at each grade level on the basis of student's scores on the Wide Range Achievement Test in Reading. All subjects had obtained an I.Q. score of ninety or better. The sample was composed of twenty-one females and twenty-seven males. Four tests from the Reitan-Indiana Neuropsychological Battery were given to assess visuo-spatial ability. It was hypothesized that visuo-spatial abilities are related positively to reading achievement and that this relationship is approximately equal at the two grade levels. Statistical analyses of results gave partial support to the first hypothesis.

The Validity of the Torrance Tests of Creative Thinking (open access)

The Validity of the Torrance Tests of Creative Thinking

The purpose of this study was to assess content and concurrent validity of the Torrance Tests of Creative Thinking (TTCT). The subjects were thirty-four art majors at North Texas State University between the ages of nineteen and thirty-nine. Content validity for the TTCT, as assessed by seven judges (art professors), was very high; concurrent validity was very low. Only one judge's ranking of the criterion was significantly intercorrelated with that of the other judges (p<.05). There were no significant rho correlations between the TTCT and the criterion (p<.05). The t-ratio differences between the males and females, for all tasks of the TTCT, were non-significant (p<.05). It was concluded that the TTCT were not appropriate for use with adult art majors.

The Minor Choral Works of Hector Berlioz (open access)

The Minor Choral Works of Hector Berlioz

The minor choral works are those exclusive of the well-known choral works. Symphonic movements for chorus are also excluded. Conflicting and incomplete information from the composer himself and from secondary sources were principal research problems. The published letters, the memoirs, and a small number of secondary sources, containing little more than passing references, form the body of the research material beyond the scores themselves. The arrangement is by opus number, with unpublished works inserted chronologically by date of composition. A description of the circumstances surrounding each work' s composition precedes a study of the music within each chapter. The last chapter delineates stylistic characteristics of the minor choral works.

The Vacuum Ultraviolet Spectra of Cyclohexane, Cyclohexene, 1,4-Cyclohexadiene, Isotetralin, and Several Methyl Substituted Analogs (open access)

The Vacuum Ultraviolet Spectra of Cyclohexane, Cyclohexene, 1,4-Cyclohexadiene, Isotetralin, and Several Methyl Substituted Analogs

A paucity of literature exists on the Independent System analysis of adjacent, parallel transition dipoles. Applying this theory and certain spectral information semiemperical calculations were made to predict absorption profiles and band intensities. To aid in the assignment of the 7*+7 absorption bands it was necessary to obtain the vacuum ultraviolet spectra of cyclohexane and cyclohexene. Because the spectra of these molecules contained sharp, atomic-like absorption bands a Rydberg series could be fitted to certain absorptions, thus the determination of their ionization potentials. Using Independent System analysis profiles and intensities of 7*+q-- absorption bands ins 'several methyl substituted 1,4- cyclohexadienes and isotetralin were predicted where general agreement was found with observed experimental spectra.

From Peaceful Militancy to Revolution: An Analysis of the Rhetorical Structure of the Women's Social and Political Union in Great Britain, 1903-1914

This study focused on the rhetorical structure of the Women's Social and Political Union. An interdisciplinary methodology was used to examine the components of rhetorical structure: ideology, goals, leaders, membership, and strategies. The rhetorical structure became the thread which held the movement together and provided the impetus for its progression and through four stages: formation and development, the beginning of militancy, the flourishing of membership, and the eruption of violence. The final stage brought about differing ideologies, inconsistent goals, and a divided membership. Although the rhetorical structure was shattered and the movement ended, it succeeded in changing the Victorian image of women and contributed to the larger women's movement.

The Motivation of Clarissa Harlowe (open access)

The Motivation of Clarissa Harlowe

This paper proposes that Samuel Richardson consciously created the motivational complexity of Clarissa Harlowe. The arguments are the following: eighteenth-century scientific interest in motivation influenced Richardson, his Puritanism led him to suspect and emphasize motive, his frequent use of the word motive suggests an awareness, his choice of the epistolary form is ideal for revealing motives, his attention to the ambiguity of motives indicates his interest, and his complexly motivated Clarissa demands a conscious creator. The last argument constitutes the principal section of the study, and Clarissa's motives are analyzed from the events prior to the elopement, through the rape in London, and finally to her death. She is studied as a product of eighteenth-century decorum, individualism, and Puritanism, but also as an intricate personality.

Microwave Line Widths of the Asymmetric Top Formic Acid Molecule (open access)

Microwave Line Widths of the Asymmetric Top Formic Acid Molecule

This work consisted of an experimental investigation of the formic acid (HCOOH) molecule's rotational spectrum. Measurements of line widths were obtained for J = 5, 12, 13, 19, and 20 for a pressure range from 1 to 10 microns. A linear behavior between Av and p was observed as predicted by theory. The line width parameter Avp was observed to depend on the quantum number J. Hard sphere collision diameters b1 were calculated using the obtained AvP values. These deduced hard sphere values were found to be larger than the physical size of the molecule. This result was found to be in general agreement with other investigation in which long range forces (dipole-dipole) dominate.

The Effect of Elimination of Subvocalization with Electromyographic Feedback on Reading Speed and Comprehension

The purpose of this experiment was to study the effect of audio feedback from an electromyograph on reading speed and comprehension. The subject reduced as much audio feedback, and thus laryngeal tension, as possible, thus permitting more efficient reading. After baseline, the subject received twelve half-hour practice sessions, six ten-minute testing sessions on easy, or light, material and six ten-minute testing sessions on difficult material. A post-test without feedback was given after training and a follow-up test, without feedback, was given. This method of training permits a higher rate of reading speed, while allowing the subject to process complex information and maintain a constant level of recall.

Economic Development in Ghana: Some Problems and Prospects (open access)

Economic Development in Ghana: Some Problems and Prospects

After independence on March 6, 1957, Ghana, under the late President Kwame Nkrumah, turned to diverse developmental activities. Economically, Ghana was on sound footing; the balance of payments was favorable and cocoa was yielding a good harvest. In 1967, Nkrumah was ousted due to his dictatorial rule. In this study the available primary and secondary sources were utilized. Primary sources were made available by the Ghana Embassy in Washington, D. C. and by friends and relatives in institutions of higher learning in Ghana. The study is divided into five chapters. Chapter I concerns itself with a geographical survey of the country, including land, climate, people, and natural resources. Chapter II explores political developments, and Chapter III examines some of the crucial economic problems. Chapter IV explores some economic progress and Chapter V makes suggestions, some of which may seem sordid and grim, but at least they offer a "stepping stone."

Validation of the Non-Ah Speech Disturbance Ratio as a Measure of Transitory Anxiety

An investigation of concurrent validity of the Non-ah Speech Disturbance Ratio (Non-ah SDR) with the State Form of the State-Trait Anxiety Inventory (STAI). Twenty male college students talked on an anxiety-arousing topic before female audiences who rated observed anxiety. Each subject completed the State and Trait Forms of the STAI. Reliabilities were, by the Intraclass correlation for Raters on Day 1, .63 (p<.01) and Day 2, .20 (p<.05). Pearson's r for scorers was .98 (p<.01). The Non-ah SDR and all other measures of anxiety correlated. A partial correlation test found the naive ratings significantly determined by manifest speech disturbance, as measured by the Non-ah SDR. Certain categories of speech disturbance were only infrequently utilized and added little to the measure as a whole.

Sex Dimension of the Dogmatism Scale: A Factor Analysis

The problem of this study was to factor-analyze Rokeach's Dogmatism Scale and examine the factor structures of the scale for differences in the solutions obtained for the male and female groups. It was hypothesized that the Dogmatism Scale consists of several discriminable dimensions of the construct dogmatism and that these dimensions differ significantly for males and females. The dogmatism scale was administered to 186 male and 115 female college students. The male and female solutions yielded thirteen and sixteen orthogonal factors, respectively. Six male factors and eleven female factors were unique to their respective sex groups, indicating that the Dogmatism Scale is multidimensional and that significant sex differences are found when these dimensions are examined.

Transactional Analysis in the Elementary Classroom: PAC for Children

The focus of this study is on the development of an original script designed to introduce concepts of structural and transactional analysis to elementary school children. Included in Chapter One are reviews of Transactional Analysis and the PAC communication model. Classroom application of Transactional Analysis principles is examined in Chapter Two. Chapter Three examines needs and characteristics of young children. Qualities of good children's literature are discussed in relationship to the selection and explication of script material. The manuscript appears in Appendix B. This report accepts evidence that Transactional Analysis training can be an additive part of the elementary school curriculum. It further proposes that story material conscientiously designed for young children could prove effective and entertaining training vehicles for Transactional Analysis concepts.

Euclidean Rings

The cardinality of the set of units, and of the set of equivalence classes of primes in non-trivial Euclidean domains is discussed with reference to the categories "finite" and "infinite." It is shown that no Euclidean domains exist for which both of these sets are finite. The other three combinations are possible and examples are given. For the more general Euclidean rings, the first combination is possible and examples are likewise given. Prime factorization is also discussed in both Euclidean rings and Euclidean domains. For Euclidean rings, an alternative definition of prime elements in terms of associates is compared and contrasted to the usual definitions.

The Transcendental Experience of the English Romantic Poets

This study is an exploration into the Romantics' transcendence of the dualistic world view and their attainment of a holistic vision. Chapter I formulates a dichotomy between the archaic (sacrosanct) world view and the modern (mechanistic) world view. Chapter II discusses the reality of the religious experience in Romanticism. Chapter III elucidates the Romantics' use of mystic myths and noetic symbols. Chapter IV treats the Romantic transcendence of the dualistic world view and the problems of expressing the transcendental experience in aesthetic form. Supporting theories include those of Henri Bergson, Martin Buber, Samuel Taylor Coleridge, and M. H. Abrams. The study concludes by assessing the validity of the Romantic vision in the modern world.

Relationship of Internal-External Locus of Control and Performance in a Weight-Control Program

This study explores the relationship between internal-external locus of control and some characteristics of overweight subjects in a weight-control program in the summer and fall of 1973. Only white, female, over-weight, and obese subjects were used. From this study, it appears that Rotter's I-E concept applies to weight loss. This one significant finding lends support to research that internals control their impulses better than externals and that internals seem to learn and retain relevant information better than externals.
