Opthalmic Use Of Sodium Cephalothin: An In Vivo Comparison (open access)

Opthalmic Use Of Sodium Cephalothin: An In Vivo Comparison

A rabbit keratoconjunctivities model was used to evaluate ophthalmic formulations containing 1 percent sodium cephalothin in silicon oil, a 1 percent sodium cephalothin aqueous solution, and a 0.3 percent gentamicin sulfate solution. Rabit eyes were inoculated intracorneally with Pseudomonas aeruginosa, Staphylococcus aureus, or Streptococcus pneumoniae, After topical treatment, none of the antibiotic formulations were effective in the P. aeruginosa model; all three showed good activity against S. aureus, and against S. pneumoniae, the caphalothin formulations were more effective than gentamicin.In a related stability study, the cephalothin potency of the silicon formulation was maintained for 16 weeks at 4, 25, and 450 C These studies suggest that sodium cephalothin can be formulated as an effective and stable ophthalmic dosage form.

Scientific Reality in C. P. Snow (open access)

Scientific Reality in C. P. Snow

Twentieth-century science proves that heredity and environment function similarly in all named living species except one--Homo sapiens. Man alone, through his intellect, forms language and culture, thereby affecting his environment so that he participates in the process of his own creation. This participation so links humans that each man extends outside himself creating of the human race a single, whole fabric. C. P. Snow, aware of this communal reality, notes the present lack of communication between scientists and humanists. He contends that this lack, described as the two-cultures split, endangers both the practical survival of Western civilization and mankind's understanding of its own humanity. This study analyzes modern scientific reality and shows that Snow's articles, lectures, and novels articulate that reality and confirm the merit of Snow's observations.

Effects of Cigarette Smoke Condensates on Cultured Human Lymphocytes and Separation of Benzo-α-Pyrene Metabolites by High Pressure Liquid Chromatography (open access)

Effects of Cigarette Smoke Condensates on Cultured Human Lymphocytes and Separation of Benzo-α-Pyrene Metabolites by High Pressure Liquid Chromatography

Cigarette smoke condensates from all cigarettes tested were found to be potent inducers of AHH enzyme in cultured human lymphocytes and, with the exception of Kent Lights and Carlton CSC's, all were found to be toxic under the experiment conditions. Most of the AHH inducing activity was found in basic and neutral fractions of the lAl standard cigarettes. A radiometric assay of BP metabolites in cultured human lymphocytes was developed in which we were able to separate the primary metabolites and the secondary metabolites from the parent compound (BP) by neutral alumnia HPLC. The primary metabolites were further separated by a selective enzyme hydrolysis and/or reverse phase HPLC.

Thundershowers: A Novella, with a Commentary (open access)

Thundershowers: A Novella, with a Commentary

Thundershowers, an original novella, represents one person's perception of relationships between women and men. The first-person narrator, Anna Slone, records her limited observations of married and unmarried couples while she pursues her own involvement with a man. She observes nothing admirable in any of the relationships between men and women in the story, and her own romance falls short of her expectations. The only nurturing love that she records passes between herself and two other women, her mother and a friend. Thundershowers is not meant to be a suggestion that all woman-man relationships are soulless or that real love can exist only between women. Set in a Colorado resort, the action focuses on several concurrent love-interests, including a faltering marriage, a traditional marriage, the engagement of two young lovers, a lighthearted sexual affair, and the short-lived but painful romance of Anna and a man whom she meets at the resort.

Young Married Couples' Attitudes Toward Children (open access)

Young Married Couples' Attitudes Toward Children

This study investigated the relationship of certain independent variables and young married couples' attitudes toward children. Church leaders in Plano, Texas, administered the Hereford Parent Attitude Survey to couples from their churches. Ninety-seven subjects comprised the main sample group. The data were analyzed using t-tests and f-tests. Women had more positive attitudes toward children than men. Parents had more positive attitudes than childless subjects. Childless subjects who plan to have children had more positive attitudes toward children than subjects who did not plan to have children or who were not sure. Income level was related to confidence in parenting. Age and sex of children and education level were not related to attitudes toward children. Based on these findings, recommendations were made for future research and education.

The Effects of Selection Risk on Sex Discrimination in Employment Decisions (open access)

The Effects of Selection Risk on Sex Discrimination in Employment Decisions

Effects of selection risk on sex discrimination in hiring were investigated. Ninety-six male and female educational administration graduate students rated ficticious resumes on suitability for hiring for the female-oriented position of secondary school teacher. Sex and selection risk level were varied, with sex of rater as an assigned factor. Analysis of variance yielded significant main effects for sex (p < .01) and selection risk level (p < .05). All ratings were lower in high selection-risk situations, with males preferred over females across both levels of risk. Results suggested that ratings were based on a stereotype of female inferiority in work efficiency, overriding job sex-orientation as a decision factor.

San Juan Ixcoi Mass: A Study of Liturgical Music in Northwestern Guatemala (open access)

San Juan Ixcoi Mass: A Study of Liturgical Music in Northwestern Guatemala

The San Juan Ixcoi Mass is part of the San Miguel Acatan Repertory which was found in the northwestern highlands of Guatemala before being purchased by the Lilly Library at Indiana University. Even though the authorship and date of the mass cannot be established, the mass is similar to works from the Josquin generation. Not discounting the few transcription difficulties as well as isolated compositional weaknesses, the San Juan Ixcoi Mass demonstrates the reasonably high quality of music that was performed and even possibly composed in northwestern Guatemala three centuries ago. A modern performance edition of the mass complete with critical notes and commentary on the transcription is included within the thesis.

Dehumanization in the Theater of Valle-Inclán and Muñiz (open access)

Dehumanization in the Theater of Valle-Inclán and Muñiz

This study proposes to establish an intrinsic relationship between Valle-Inclán and Muñiz based on the theme of dehumanization in their theater. It examines (1) the stylistic techniques which each playwright uses to depersonalize his characters, (2) the manner in which these characters dehumanize each other, (3) the role of society as the agent of dehumanization, and finally, due to each author's preoccupation with one social convention in particular (4) the devastating effects on men of the vestiges of an outmoded code of honor. The principal works used for the study are Valle-Inclán's Martes de carnaval, Luces de Bohemia, and Divinas palabras, and El tintero, Un solo de saxofón, Las viejas difíciles, and El grillo by Carlos Muñiz. Such an analysis proposes to reveal a profound literary affinity between these two writers, a bond which unites Valle-Inclán and Muñiz in a common protest against the dehumanization of mankind.

Effect of Operant Behavior on the Metabolism of 5-Hydroxytryptamine (open access)

Effect of Operant Behavior on the Metabolism of 5-Hydroxytryptamine

The role of operant behavior in the metabolism of brain 5-hydroxytryptamine (5-HT) turnover was investigated. Two and one-half hours following the administration of 150 mg/kg of para-chlorophenylalanine (PCPA), a specific inhibitor of tryptophan hydroxylase, levels of 5-HT were compared in sedentary and performing rats. Whole brain levels of serotonin were reduced in both responding and sedentary animals; however, differences between these groups were not statistically significant. The drug induced decrease in 5-HT levels was accompanied by a significant decrease in session responding. The degree of suppressed responding could be correlated with the level of 5-HT following PCPA, suggesting that the metabolism of serotonin is in part modulated by the rate of responding as maintained by the operant schedule.

The Romanticism of Harper Lee's To Kill a Mockingbird

The thesis examines the influence of the Romantic elements of Harper Lee's To Kill a Mockingbird upon the novel's characterizations, structure, tone, and themes. Chapter One contains a critical survey of criticism about the novel and a list of Romantic elements. Chapters Two, Three, and Four present the three most important of those elements. Chapter Two is the exploration of the novel's Gothic traits. Chapter Three explores the Romantic treatment of childhood's innocence and perspicacious vision as it pertains to Dill, Jem, and, in particular, Scout. Chapter Four is a detailed study of Atticus Finch, the novel's Romantic hero, who expresses or incorporates many of the most important elements of Romanticism in the novel.

Competence Theory and the Appreciation of Novel and Familiar Humor (open access)

Competence Theory and the Appreciation of Novel and Familiar Humor

According to Suls' (1972) incongruity model for the appreciation of jokes, humor with which recipients are familiar should not be perceived as funny because the ending is predictable. Suls (1975) later proposed that familiar humor is appreciated because of the sense of competence derived from adequately remembering the joke. This study examined Suls' theories by having subjects rate jokes on two occasions and supply their punch lines on the second occasion. Statistical significance was determined through the use of the t test for correlated means. Jokes for which punch lines were recalled were perceived as significantly less funny than on the first occasion. The results did not support predictions made from Suls' competence theory but did support those derived from Suls' incongruity model.

"I'm Leading Now": The Argument for Widmerpool as the Central Character of a Dance to the Music of Time

This study argues that the central character of Anthony Powell's novel, A Dance to the Music of Time, is Kenneth Widmerpool. A survey of the criticism available on The Music of Time, contained in this study's introduction, indicates that there are a few precedents for this argument but there there are no thorough analyses of the problem from which this argument arises: the identity and function of the novel's central character. This study is organized around separate analyses of three of the novel's elements. Chapter Two deals with characterization, Chapter Three with theme, and Chapter Four with structure. This study concludes that, based on evidence availabe in The Music of Time itself, Widmerpool is the central character.

Presidential Reconstruction in Texas 1865-1867 (open access)

Presidential Reconstruction in Texas 1865-1867

Presidential reconstruction in Texas proceeded under the direction of provisional governor Andrew Jackson Hamilton, a Texas Unionist. Texas Unionists had deep political roots in pre-war politics and sought to reconstruct along moderate lines. Following the constitutional convention of 1866, conservative James Webb Throckmorton won the gubernatorial race against Unionist Elisha Marshall Pease. Throckmorton's administration did very little to curb the intense violence directed at Unionists in Texas, and the conservative legislature passed legislation repressive to blacks. Texas Unionists grew increasingly radical, and Throckmorton clashed with the federal military over the question of authority. After the Radicals in Congress passed the Reconstruction Acts, Throckmorton was removed as governor, and E.M. Pease was appointed in his place, ending presidential reconstruction in Texas.

The Effect of Hypothalamic Stimulation on the Phagocytic Activity of the Reticuloendothelial System (open access)

The Effect of Hypothalamic Stimulation on the Phagocytic Activity of the Reticuloendothelial System

Although research has linked the central nervous system with changes in immunoresponsivity, research on the possible role of the central nervous system in altering reticuloendothelial activity is lacking. This study investigated the possible relationship between hypothalamic structures and changes in responsivity of the reticuloendothelial system. Eight male albino rats received bilateral electrode implants in the ventromedial area of the hypothalamus and, following brain stimulation, reticuloendothelial activity was assessed 3, 6, 12, 24, and 96 hours after stimulation. Brain stimulation decreased phagocytic activity of the reticuloendothelial system. These findings may increase our understanding of a possible neural mechanism underlying relationships between stress and resistance to disease states.

Prediction of Hearing Thresholds by Means of the Acoustic Reflex with Autistic and Normal Subjects (open access)

Prediction of Hearing Thresholds by Means of the Acoustic Reflex with Autistic and Normal Subjects

This study concerns audiometric evaluation and prediction of hearing loss in the autistic child based on information derived from acoustic reflex thresholds. Two groups (autistic males and normal children) of five subjects each were utilized. Results indicated that the acoustic reflex method consistently predicted significantly higher hearing thresholds for autistic subjects than operant pure-tone audiometric procedures. Furthermore, the acoustic reflex thresholds were significantly less sensitive in the autistic group than in the normal group, suggesting that the acoustic reflex response is somehow altered in autistic individuals. These findings are consistent with earlier work which hypothesized that autistics, manifest an organic brain lesion which interferes with the propagation of auditory information.

The Archetype of the Great Mother in Three Contemporary Films

This thesis is designed to determine the impact of the archetype of the Great Mother on the plot, characterizations, and interpersonal relationships in three contemporary films. Chapter I describes the elements and applications of the archetype and the Jungian analysis employed in the study. Chapter II details the phases of the Great Mother archetype and discusses Jung's process of individuation and how the Great Mother controls this quest. Chapters III, IV, and V focus on The Heretic, Network, and Looking for Mr. Goodbar respectively. Chapter VI summarizes the existence and power of the archetype in the films and postulates that the image of women in film may be stereotyped due to the Great Mother archetype.

NAD+-Dependent 15-Hydroxyprostaglandin Dehydrogenase from Swine Kidney: Characterization and Kinetic Mechanism

Cytoplasmic 15-hydroxyprostaglandin dehydrogenase from swine kidney was purified to specific activity of 1.2 U per mg protein, by chromatographic techniques. Native molecular weight of enzyme was estimated at 45,000. Enzyme was inhibited by sulfhydryls, diuretics, and various fatty acids. Substrate studies indicated NAD+ specificity and ability to catabolize prostaglandins, except prostaglandin B and thromboxane B. Initial velocity studies gave intersecting plots conforming to a sequential mechanism. 15-keto-prostaglandin exhibited linear noncompetitive production inhibition with respect to either prostaglandin or NAD+; NAD yielded linear competitive production inhibition with respect to NADH. Results, and those of dead-end inhibition and alternated substrate studies, are consistent with an ordered Bi-Bi mechanism: NAD+ is added first, then prostaglandin; then 15-keto-rostaglandin is released, then NADH.

Analysis of American College Test Scores and College Grade Point Average as Success Indicators on the State Nursing Board Examination

The purpose of this study was to compare the relationship between the American College Test (ACT) sub-test scores, nursing courses' grade point average, college cumulative grade point average and the State Board Test Pool Examination (SBTPE) sub-test scores. Data from 227 nurses were analyzed utilizing three procedures: Pearson product-moment coefficient; multiple correlation coefficient; and linear regression equations. Conclusions were that several ACT sub-test scores could yield useful information on admission; the college cumulative grade point average was the most reliable indicator of success on the SBTPE; and an ACT composite score of eleven was the minimum value required to pass the SBTPE sub-tests with a score of at least 350.

La violencia en el Teatro de Guillén de Castro (open access)

La violencia en el Teatro de Guillén de Castro

This analysis, written in Spanish, compares the use of violence in four of Castro's dramas with its use in their sources and in the works of other Golden Age authors. Chapter II investigates the manner in which the plays based on Greek myths compare with the original stories and with the ancient Classical theater. Each of the four following chapters compares one of Castro's plays to contemporary works with the same plot. The conclusion indicates that Castro's plays do not show an extraordinary use of violence. In some instances Castro demonstrates more restraint than the other dramatists. Thus, Castro, as a typical author of his epoch, does not deserve his reputation for writing excessively violent works.
