Effects of Long-Term Moderate Ethanol Intake on the Stress Response in Rats

Description: The effect of ethanol on the stress response in rats was examined. Experimental animals were given 0.25 ml of 28 percent ethanol or 0.25 ml of water orally once a day, five days a week, for a period of twelve months and were then subjected to fifteen minute cold stress. Corticosterone levels in ethanol-treated males following stress were significantly lower (22 percent) than in the sham group. Adrenal weights in sham-treated females were significantly higher (15 percent) than in the ethanol group at the end of twelve months. Mortality in sham-treated males was significantly higher (60 percent) than in ethanol-treated males. The effects observed may be due to the sedative action of ethanol on cortical centers controlling the hypothalmus.

The Importance of Staff Cohesiveness in Treatment Effectiveness as Demonstrated by Client Self-Disclosure

Description: Much research has studied cohesiveness within client groups in terms of making therapeutic gains. These studies have defined cohesiveness in terms of a) attraction of the group as perceived by a group member, b) how clearly each member sees his/her role within the group, and c) the effectiveness of one's skills in attaining group goals. Little research has dealt with the role of staff cohesiveness in developing an effective treatment program. Effectiveness, in this study, is defined as the degree to which clients are willing to disclose personal information to the staff. The results show a positive correlation between staff's perceived effectiveness with clients and the clients' willingness to self-disclose. On-hand experience with clients seems important in involving clients in therapy.

An Exploratory Study of Laryngeal Movements During Performance on Alto Saxophone

Description: The purpose of this study was to investigate laryngeal movements in selected performance situations on alto saxophone. The specific research problems were to describe glottal activity in three selected musicians as they performed musical tasks with (1) various pitch ranges and registers, (2) fortissimo and pianissimo dynamic levels, (3) crescendo and decrescendo, (4) long tones with vibrato, and (5) legato and staccato styles of articulation. A fiberoptic laryngoscope was employed to gather the visual images, which were recorded on a sound synchronized video tape. A rating system was devised to provide graphic representation of the data. Results of the data indicated that the glottis was used as an airflow constrictor in certain performance situations, especially in pianissimo performance. Other conclusions were drawn, and suggestions for further research were discussed.

Helping Among Children

Description: This study investigated the effect of cost-of-escape on helping among children. Forty-four children between the approximate ages of six and twelve served as subjects. The experiment was performed in a natural setting using an ice cream truck. The driver (experimenter) manipulated the cost-of-escape and then had an "accident." The easy-to-escape group received their ice cream before the driver spilled 300 spoons on the ground. The difficult-to-escape group had paid for their ice cream but had not received it before the "accident" occurred. The number of spoons picked up by each condition and the lapse time before a member of each group began to help was recorded. No differences were found between the groups (all ps > .05). Implications for cost-of-escape were discussed.

Fatigue Related Changes in the Body Motion and Force Application During the Performance of Consecutive Chin-ups

Description: The purpose of this study was to examine the effects of fatigue on force application and resulting movement patterns during the performance of consecutive chin-ups. Special attention was directed toward relating any fatigue effects to upper limb strength dominance. Twenty male adult subjects each performed one trial. Each trial consisted of consecutive chin-ups. Fatigue caused changes in the movement patterns, duration of movement and force applied through the supporting hands. Throughout the performance greater vertical forces were applied through the dominant upper limb segment with the application of these forces resulting in horizontal displacement of the total body center of gravity toward the dominant hand.

Rorschach Interpreters: Relationship to Spatial Intelligence

Description: In an attempt to find meaningful predictors of the ability to interpret Rorschach protocols by clinicians, a paradigm change (Kuhn, 1962) was instigated by using as predictors the scores of the perceptual organizational abilities of 30 subjects, and their ratings of favorableness toward the Rorschach in terms of its usefulness as a clinical tool. The subjects were first year, graduate psychology students, and the Haptic Visual Discrimination Test (HVDT) was the instrument used to measure perceptual organization. A multiple linear regression analysis was computed, and the data supported the hypothesis that perceptual organization and favorableness are of significant predictive value (R = .54, F(2, 27) = 5.43, p = .01). The standardized beta for usefulness was .47 (p = .008) and the HVDT beta was .33, (p = .05). The results were interpreted as applying to Rorschach validity research methodology and pedagogy.

Identification and Characterization of a Calcium/Phospholipid-Dependent Protein Kinase in P1798 Lymphosarcomas

Description: Calcium/phospholipid-dependent protein kinase (PKC) was partially purified from P1798 lymphosarcoma. Phospholipid-dependence was specific for phosphatidylserine. PKC phosphorylated Histone 1, with an apparent K_m of 14.1 μM. Chlorpromazine, a lipid-binding drug, inhibited PKC activity by 100%. Further studies were undertaken to establish analytical conditions which could be applied to the study of PKC in intact cells. The conditions included (1) determining optimum cell concentration for measuring PKC activity, (2) recovering PKC into the soluble fraction of cell extracts, (3) evaluating calcium and phospholipid requirements of PKC in this fraction, and (4) inhibiting PKC in this fraction. Final studies involved treatment of intact cells with potential activators. Both phytohaemagglutinin and a phorbol ester increased PKC activation.

Syntheses of a New C₂₂H₂₈ Cage Hydrocarbon System and 2,2- Tetramethylene-1 /4-Dibromobutane

Description: (1). An improved method for synthesizing bicyclo (2,2,1) hepta-2,5-diene-7-spiro-1'-cyclopentane (5) has been developed. Thermal reaction of compound (5) with neat iron pentacarbonyl under nitrogen atmosphere affords the corresponding cage dimer (6). Some aspects of the syntheses, spectra, and chemistry of compound (5) and (6) are discussed. (2). A structure isomer of decamethyldodecahedrane (C₃₀H₄₀), molecule (11), is expected to be synthesized via thermal reaction of iron carbonyl complexes with compound (10). An intermediate in this synthesis, 2,2- tetramethylene-1,4-dibromobutane (9) was efficiently synthesized starting from cyclopentanone. Some aspects of the syntheses, spectra, and chemistry of compound (1) to (9) will be discussed.

Standardization of a Memory Test with an Elderly Population

Description: The Aronson Shopping List is a short-term memory test which integrates current knowledge of brain-behavior relationships in assessment. The test was designed to detect deficiency in fluid intelligence. The goal of this study was to standardize the test on an elderly population. The sample was composed of 67 males and females whose ages ranged from 62 to 89 years. It was found that recent stressful events did not account for variation of performance on the ASL. The reliability of the test, established by means of a test and alternate form retest procedure, was found to be .70 after an average of eleven months. Percentiles are presented indicating performance comparisons. Further experimentation would be needed to establish whether the test would be useful to designate organic brain pathology.

The Formation of a Theory on Screenplay Imaging Through the Adaptation of Eisenstein's Principles of Montage

Description: The purpose and problem of this thesis is to formulate a theory on screenplay aesthetics with Eisenstein's montage as the mother theory providing the aesthetic nourishment for the proposed concept of imaging. The theory of screenplay imaging proposes that the screenplay is a montage of sub-narratives occurring in the sensual, emotional, and intellectual dimensions and expressing the grand narrative theme. It further suggests that the interaction between the screenplay and the reader-interpreter should yield a prolificity of interpretation with a unified meaning. The thesis consists of five chapters. Chapter I, Introduction, lays the background for subsequent arguments. Chapter II, The Principles of Montage, discusses Eisenstein's theory. Chapter III, The Theory of Imaging, explains imaging and develops Gonzalez's Model of Imaging. Chapter IV, The Principles of Sensual, Emotional, and Intellectual Imaging, explains the three dimensions with examples. Chapter V, Conclusion and Recommendation, suggests improvements and applications of the theory.

A Descriptive Study of the Public Relations Practices at Hardin- Simmons University

Description: This study examined the public relations practices-- the concept, structure, functions, goals and objectives, procedures, and standards of performance--at Hardin-Simmons University in Abilene, Texas. The study concluded that the public relations practices provide an effective, well-organized, well-planned and well-executed program based on formal goals and objectives, definite philosophy and purpose, and criteria for measurement of effectiveness. Although the program has a good sense of direction, it lacks focus, largely because of the mingling of public relations and fund-raising responsibilities in some staff positions and a lack of separate standards of performance for each staff member. Recommendations to strengthen the program include separate and distinct public relations and fund-raising responsibilities in each staff position and standards of performance for each staff member.

The Adenosine Antagonist Aminophylline Attenuates Pacing-Induced Coronary Functional Hyperemia

Description: Left coronary blood flow (LCBF), left ventricular oxygen, extraction [(a-v)O₂ ], and myocardial oxygen consumption (MVO₂) were monitored in 10 dogs. HR was paced at 120 bpm and then increased to 180 bpm to elicit a hyperemic response (ΔLCBF). During the hyperemia, the vaso-dilatory response to exogenous adenosine (F_AD) was tested. Twenty min. after injection of aminophylline (100 mg/i.v.), HR was again increased. F_AD was again tested. The pacing-induced increase in MVO₂ (ΔMVO₂) was not affected by aminophylline (P>0.05). However, the slope ΔLCBF/ΔMVO₂ was decreased, and the slope (a-v)O₂ /ΔMVO₂ was increased. F_AD was also decreased and the magnitude of the reduction was correlated with the decrease in ΔLCBF/ΔMVO₂ (r=0.82). These results suggest that adenosine may play an role in coronary functional hyperemia induced by increases in heart rate.

Effects of Suspended Solids on Bioavailability of Chemicals to Daphnia magna and Pimephales promelas

Description: Three suspended solids types containing a range of physicochemical characteristics were used to determine the effect of suspended solids on the bioavailability of acenaphthene, 1,2,4,5-tetrachlorobenzene, zinc, and chlordane to Daphnia magna and Pimephales promelas. Generally, the bioavailability of zinc and chlordane decreased due to interactions with all suspended solids types while bioavailability of acenaphthene and 1,2,4,5-tetrachlorobenzene were not clearly reduced. Partition coefficients and slope of dose-response curves related chemical characteristics and organism sensitivity, respectively, to experimentally determined results. It is believed that the biologically available form of these chemicals to Daphnia magna and Pimephales promelas resides in the aqueous phase.

Dependency in the Clinical Ecology Patient

Description: Dependency is defined as authentic or pathological and is seen as a component important to the treatment of patients with chronic illness. It is hypothesized that a significant portion of ecology patients will meet the criteria for pathological dependence and differ on psychological and physiological parameters from those who do not. This study strongly supports the first two hypotheses but does not find that the two groups differ physiologically. One hundred eleven variables are surveyed. Fifty-two show significant differences between the groups and 29 are significant at greater than the .0001 level. A discriminant analysis was used to determine the least number of orthogonal variables that best discriminate between the groups. These are MMPI Scales 8, 3, subscale Ma2, employment status, and early childhood illness.

A Comparison of Attitudes of Photojournalists and Photojournalism Educators: The Best Literature About Photojournalism and Its Usefulness

Description: This study has two purposes: (1) to provide a reference tool--a list of the best books, articles, and audiovisual materials about photojournalism, and (2) to make a general evaluation of available literature. In response to a mail survey, photojournalists and photojournalism educators recommended twenty-four sources of information about photojournalism in twenty subject categories. Respondents believe reading about photojournalism is important in helping professionals do their jobs well. But, they do not think there is enough up-to-date information available. Further, a majority think photojournalism literature is unrealistic, poorly written and designed, and ineffective in preparing students.

Amerikanuak eta Asmoak: New World Basques and Immigration Theories

Description: The focus of this thesis is the relationship between immigration historiography and the history of Basque migration to the United States. The depictions of immigration presented by historians Oscar Handlin, Marcus Lee Hansen, and John Higham have been influential in immigration historiography and are presented in the first chapter. The second chapter contains a description of Old World Basque culture and the third chapter presents a brief history of Basque migration to the United States. The fourth chapter discusses to what extent the immigration theories presented in chapter one match the Basque experience in the New World. The concluding chapter contains some observations on the nature of immigration historiography, on the Basques, and on new directions for research.

Swinging Gait Patterns and Preferred Rung Spacing During Free Choice Horizontal Ladder Traverses

Description: Fifty-one subjects each performed two trials which consisted of traversing a horizontal ladder. Film records were made of each trial using a high-speed camera. Absolute and relative temporal and kinematic parameters were obtained from the film records. The conclusions were that there was no age related interaction or differences in preferred rung spacing or contact/airborne times. A Chi-Square analysis did show a preference for a specific gait pattern for the six year old age group.

Isolation and Partial Characterization of Lecithin Cholesterol Acyltransferase and High Density Lipoprotein from Hog Plasma

Description: Lecithin:cholesterol acyltransferase (LCAT) was purified 30,000-fold from hog plasma in a homogeneous state as indicated by polyacrylamide gel electrophoresis. The purified enzyme had an apparent molecular weight of 66,000 and was found to contain about 21.4 percent (w/w) carbohydrate. The properties of hog LCAT including amino acid composition were compared with human LCAT. High density lipoprotein (HDL) was isolated from the hog plasma by an immunoaffinity column chromatography. The isolated HDL showed nearly identical lipid-protein composition although it contained additional protein components when it was compared to HDL isolated by a traditional method involving ultracentrifugation.

A Functional Analysis of Connectives in English Composition: Implications for the Teaching of English as a Second Language

Description: Errors by ESL writers involving connectives show a need for changes in the current teaching approach of composition teachers, an approach which reflects a lack of attention to the discourse function of connectives on the part of linguists and rhetoricians. More recent studies in text and functional grammars reveal that factors other than syntax control conjunctive use. These include pragmatic differences between spoken and written language, the role of semantics in defining dependency, and discourse functions of connectives. Conjunction is seen as part of a continuum of semantic dependency that is manifested as degrees of syntactic complexity. Teaching methods should take into account semantic and pragmatic factors and encourage learning of connectives through activities such as revision of student writing for content as well as mechanics.

Program Components for a Corporate Wellness Program

Description: This study was to determine if the importance assigned by health educators (judges) to components of corporate health promotion programs is the same as or different from program components most frequently offered by corporations for employees. This involved establishing a list of program components that judges felt were important for wellness programs and comparing this list with programs actually existing in polled corporations. A literature review was used to establish an initial list of program components. Thirty-eight judges returned questionnaires incorporating the list. A Spearman's rho and scattergram were used to test for correlations between judges' opinions and corporate practices. The report concludes that no correlation exists but that there is agreement among the judges polled that corporations should promote employee wellness programs.

Perspectives on the Musical Essays of Lorenz Christoph Mizler (1711-1778)

Description: This study provides commentary on Mizler's Dissertatio and Anfangs-Gründe des General Basses. Chapter V is an annotated guide to his Neu eröffnete musikalische Bibliothek, one of the earliest German music periodicals. Translations of Mizler's biography in Mattheson's Grundlage einer Ehrenpforte and selected passages of Mizler's Der musikalischer Staarstecher contribute a sampling of the critical polemics among Mizler, Mattheson, and Scheibe. As a proponent of the Aufklärung, Mizler was influenced by Leibnitz, Thomasius, and Wolff. Though his attempts to apply mechanistic principles to music were rejected during his time, his founding of a society of musical sciences, which included J. S. Bach, Telemann, Handel, and C. H. Graun as members, and his efforts to establish music as a scholarly discipline deserve recognition.
