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.
