Cardiovascular and Hormonal Responses to Orthostasis Following Four Hours of Head-Down Rest in Endurance-Exercise-Trained and Untrained Subjects

Description: Cardiovascular and hormonal responses to +700 head-up tilt (HUT: orthostatic challenge) were compared between six endurance exercise trained (ET) and six untrained (UT) subjects prior to and immediately following 4 hours of -60 head-down rest (HDR). The ET subjects showed a significant (P < 0.05) decrease in orthostatic tolerance time (pre syncopal symptoms) during post-HDR HUT, while no difference was observed between ET and UT groups in pre-HDR HUT. The volume regulatory hormonal responses were similar between ET and UT groups whether during HUT or HDR. The pre-syncopal subjects had a greater increase in plasma arginine vasopressin and less increase in plasma renin activity and plasma aldosterone during HUT than was observed in non syncopal subjects. These data suggest that HDR deconditioning was more effective in the ET subjects.

The Relationship Between Nightmare Frequency and Hypnotic Susceptibility: Valid Correlation or Context-Mediated Artifact?

Description: The possibility that a positive correlation between nightmare frequency and hypnotic susceptibility reported by Belicki and Belicki (1986) was an artifact of administering a sleep questionnaire in the context of a hypnosis experiment was tested in the present study. Measures of vividness and absorption were also administered. Forty subjects, twenty of whom were told that the measures were related to hypnotic responding, completed the questionnaires immediately prior to hypnosis. Twenty other subjects, who completed the questionnaires in contexts unrelated to hypnosis, were later hypnotized. The hypothesis that context of administration of the questionnaires influenced the relationship between the measures and hypnotic susceptibility was not supported. Replication using a larger sample was recommended.

Symptom Based Classification of Environmentally Ill Patients: an Exploratory Study

Description: The purpose of the present study was to discern a symptom pattern for environmentally ill patients and provide evidence of the uniqueness of the resultant pattern to this population. Patients' environmental exposure was confirmed by the presence of toxins in the blood serum. All patients were administered psychological and physical symptom checklists, the Clinical Analysis Questionnaire, and a standardized intermediate neuropsychological examination. Results indicate a response pattern of symptoms including fatigue, low energy, weakness, poor concentration, poor memory, poor comprehension, headaches, aches and pains, clumsiness, sinus discomfort, mucus, eye problems, restlessness, and present performance inferior to prior level of functioning. Presence of these symptoms, as well as the uniqueness of this symptom pattern was supported by comparisons of the patient and standardization groups on the two standardized tests.

A Concurrent Validation Study of a Paper and Pencil Test Battery for a Sales Position

Description: Participating in this study were 251 decorator consultants. The decorator consultant position is a direct sales position. The primary objective of this study was to demonstrate that a relationship existed between decorators' selection test scores and their job performance. The SRA Verbal Form, the EAS Numerical Ability Test, the EAS Space Visualization Test, and the Sales Attitude Checklist were evaluated as potential selection tests. Behavioral criteria and managerial ratings were used to assess job performance. Correlational analyses revealed that all the tests but the SRA Verbal Form were significantly correlated with two or more criteria.

Comparability of the WPPSI-R and the Stanford-Binet: Fourth Edition

Description: The purpose of this study was to compare the performance of children on the Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R) with their performance on the Stanford-Binet Intelligence Scale: Fourth Edition (SB:FE). One hundred and four children between 3 and 7 years of age were administered both tests. A moderate correlation was found between the WPPSI-R Full Scale IQ and the SB:FE Composite Score with a Pearson product-moment correlation of .46. This correlation suggests that the two tests are not interchangeable measures of children's intelligence. They may measure different, equally important aspects of intelligence. As both tests used are relatively new, the current findings should be considered one step in the accumulation of knowledge about the usefulness of the WPPSI-R.

Factors Relating to Upper Level Employee Support for Organizational Redesign

Description: Successful implementation of organizational redesign depends on the support of employees at all levels of the organization. This study looked at some of the factors that are related to employee support for organizational redesign. Subjects (82 support staff members of a small manufacturing plant undergoing organizational change) were administered a survey which measured employee perceptions about the change management process and the disruption the change caused to their daily routine. Eleven variables were assessed as independent variables in terms of their relationship to the dependent variable which was employee support of the organizational change. All eleven variables were significantly related to the dependent variable. The implications of these results and issues for further research was discussed.

Mutagenic Potential of Tetramethylthiuram Disulfide (42-S Thiram) on the Germ Cell Stages of Drosophila melanogaster

Description: Tetramethylthiuram disulfide (42-S Thiram), a carbamate fungicide was studied for its mutagenic potential on the germ cell stages of wild-type male Drosophila melanogaster. The mutagenicity was tested using the sex-linked recessive lethal assay (SLRL). Any lethals induced in the F2 generation were evidenced by the absence of wild-type males. Although there was an increase in mutation rates in the 42-S Thiram treated wild-type males over the control wild-type males, it was not significantly higher. According to the laboratory conditions in this preliminary study, tetramethylthiuram disulfide failed to produce mutagenic effect.

Validation of a Test Battery for the Selection of Driver Managers in a Trucking Organization

Description: This study was a concurrent validation of a paper and pencil test battery used at a national trucking company. Forty-eight driver managers were rated by their immediate supervisors with the performance appraisal covering 12 dimensions of job behavior that was developed by the experimenter. The driver managers were also administered the Wesman Personnel Classification Test, the Watson-Glaser Critical Thinking Appraisal, and the California Psychological Inventory (CPI). A biographical information blank was also developed and validated. Most validity correlations were nonsignificant, with the exception of the Dominance scale r = .25 (p < .05), the Self-control scale r = -.25 (p < .05), the Communanlity scale r = .29 (p < .05), and the Flexibility scale r = -.39 (p < .05), with overall performance.

Anger/Hostility: Reliability of Measurement and Correlates of Health History

Description: The purpose of this study was to (1) assess the reliability and validity of anger/hostility measures, (2) examine the relationship between anger/hostility and other negative emotions, and (3) examine the relationship between anger/hostility and health history. Sixty-five subjects were given the Buss Durkee Hostility Inventory (BDHI), the State-Trait Anger Expression Inventory (STAXI), the Profile of Mood States pomsS), the Clinical Analysis Questionnaire (CAQ), the State-Trait Anxiety Inventory (STAI), the Health and Wellness Attitude Inventory (HWAI), and a health questionnaire designed to provide information about past disease and alcohol/drug use. Overall, the BDHI and POMS displayed good test-retest reliability. All six of the global indices of anger/hostility intercorrelated at a significant level, thus demonstrating good concurrent validity. The six global measures of anger/hostility also correlated at a significant level with other negative emotions.

Languages in Contact: Polish and English

Description: The purpose of this study was to examine the Polish language of immigrants who came to the United States during or after World War II and to test two related hypotheses: 1. Speakers of Polish use a number of lexical intrusions. 2. Lexical intrusions differ in scope depending on whether those speakers had immigrated with minimal education or they received at least 12 years of schooling prior to their immigration. The study was conducted in the Dallas-Fort Worth area in January and February of 1990. The sample consisted of 16 informants whose interviews were recorded and analyzed in terms of lexical borrowings, cultural branches, and parts of speech. Findings supported the two hypotheses.

Student Perception of Nonverbal Behaviors of International TAs

Description: Six hundred sixty-six students were queried at the University of North Texas. The appropriate use of nonverbal behaviors of international and U.S. American TAs was surveyed. An eleven item questionnaire (Teacher Nonverbal Measure) was utilized. These questions were tested by an ANOVA. Data indicated that international TAs are less likely to use appropriate nonverbal behaviors than U.S. American TAs. Thus, it is possible to assume that international TAs are more likely to be perceived as using inappropriate nonverbal behaviors than U.S. American TAs. Also, communication competence was investigated. The Communication Skill Rating Scale was utilized and tested by ANOVA. Results indicate that international TAs are viewed as significantly less competent than U.S. American TAs.

Assessment of Functional Communication Skills in Institutionalized and Non-Institutionalized Elderly Subjects Using the Spontaneous Speech and Auditory Comprehension Subtests of the Western Aphasia Battery

Description: The purpose of this study was to determine if there is a difference in functional communication skills between elderly persons in nursing homes and those living independently in the community. Thirty non-institutionalized elderly subjects were given the Western Aphasia Battery (WAB) screening tool. These scores were compared to WAB screening scores obtained from 20 institutionalized subjects. The difference between these scores was statistically significant. The institutionalized subjects' scores were also correlated with a Facilitators Evaluation of Communication Skills (FECS) inventory. Results showed a moderate correlation between the institutionalized subjects' WAB screening score and their FECS rating. The benefits of a screening tool for elderly populations are discussed.

Development and Validation of a Ramping Treadmill Protocol for the On-Line Measurement of Four Aerobic Parameters

Description: Previously, Whipp et. al. (J. Appl. Physiol.: Respirat. Environ. Exerc. Physiol. 50(1):217-221, 1981) demonstrated the feasibility of determining four parameters of aerobic function, identified as maximum oxygen uptake (μVO_2), VO_2 at anaerobic threshold (θan), the time constant for oxygen uptake kinetics (rVO_2) and work efficiency (η), using a short duration ramped bicycle ergometer exercise test. Because of the importance of being able to measure these parameters on a variety of measurement instruments a short duration ramping treadmill protocol has been developed. The ability of this protocol to determine the four aerobic parameters has been validated against conventional methods. The results of this investigation indicate that μVO_2, θan, rVO_2 and, η may be obtained from a single, short-duration ramping treadmill test.

Symphonic Poem "New Life" for Orchestra and Yang-Chin

Description: Symphonic Poem New Life is a composition in one movement for orchestra and yang-chin. The work is divided into six continuous sections. It is written in resultant form which is a cumulative process by which all major musical elements return at the end of the work. The tritone is the prominent interval used throughout the piece. Some graphic notation is also employed. The work has a performance time of approximately 13-15 minutes. The yang-chin is a Chinese string instrument similar to the Hungarian cymbalon, which is played with a pair of small beaters. These instruments have similar ranges, and either instrument can be used in this work.

Militarization and Its Effects on Women's Economic Status: a Cross-National Study

Description: This research tested the hypothesis that militarization of societies, as defined by the percent of national budgets spent on military expenditures, has adverse effects on women's economic status relative to men's. This study also examined other predictor variables known to affect women's status. Data from sixty different nations were analyzed by means of multiple regression techniques. Results show that the militarization variable increased women's share of agriculture, which suggests that as men are mobilized into military activities, women are left to produce food for the country, a situation which can have contradictory effects on women's economic status. What is more important than militarization in predicting women's economic status relative to men's are high birth rates and sex ratios, which clearly depress women's economic opportunities.

The Effect of Long-Term Moderate Amounts of Ethanol on Paraventricular Nuclei Activity on Cold Stressed Adult Rats

Description: The effects of moderate, long-term intake of ethanol on the hypothalamic response to cold stress were examined. The long-term experimental animals were given .25 ml of 28% ethanol or .25 ml of water orally once a day, five days a week for fourteen months. A stainless steel electrode was then surgically implanted into the paraventricular nucleus, after which the animal was subjected to cold stress (-150 C, 10 min.). Recordings were taken in the forms of frequency and activity. The data clearly indicate that: (1) alcohol fed rats exhibited a suppressed response to cold stress compared to sham-fed rats; (2) this suppression of activity occurred at the level of the hypothalamus, and (3) mortality was significantly lower in alcohol-fed males than it was in sham fed males. This study clearly points out the need for further work in the area of the beneficial effects of moderate doses of alcohol.

Event Order in the Biathlon Does Not Have an Effect on Metabolic Response

Description: The purpose of this study was to examine the effects of event order on a cycling(C)/running(R) or R/C biathlon. Eight experienced male biathlete/triathletes with a mean age of 24.9 + 4.6 yr formed the sample of the study. Results show no significant interaction effects on oxygen consumption peak, oxygen consumption during steady-state, ventilation, and heart rate when C/R or R/C are performed at 70% oxygen consumption peak for subsequent R and C respectively. These results seem to indicate that the biathlete/triathlete is efficient in both C and R to the extent that event order does not significantly interact with metabolic response in submaximal cycling and running.

Topics in the Morphology and Phonology of Mandarin Chinese

Description: This thesis examines some selective cases of morphophonemic alternation in Mandarin Chinese. It presents analyses of the function -of the retroflex suffix -r and describes several conditions for tone sandhi. The suffix -r functions not simply as a noun formative. Some of the suffixed forms have consistently different meanings from the roots on which they are based. The suffix -r also plays a role in poetry as a time-filler to make each line of a poem fulfill the requirements of the strict number of characters and rhyme. This thesis also explains what causes the tone pattern of words such as xiaojie and jiejie to be pronounced differently. These tonal changes are found to be related to the way in which a word is formed. Compounding, reduplication and suffixation differ with respect to how they effect tone sandhi. Tone alternations in actual speech are explored to determine how tone sandhi produces each pronunciation and how grammatical structure and other factors are relevant.

Sensitive Microtiter Assays for NAD, NADP and Protein Quantification in Human Lymphocytes

Description: Intracellular levels of NAD are of renewed interest in clinical and basic science research due to the new discovery of enzymes which utilize NAD as a substrate. Microtiter assays for the determination of NAD, NADP and protein were developed as modifications of previously published methods. The resulting assays are simple, cost effective and sensitive. An improved method of isolating lymphocytes was also developed. The resultant procedure requires one hour and removes greater than 99.9% of the platelets. Lymphocyte pools were stabilized with the addition of ADP-ribosyltransferase inhibitors and a modified extraction procedure. These studies have led to the development of a method for evaluation of NAD in human lymphocytes that is sensitive, selective and suitable for automation.

In the Beginning was the Word: Hebraic Intertextuality and Critical Inquiry of Ambrose Bierce

Description: This study corroborates theories that ordinary representation of narrative time as a linear series of "nows" hides the true constitution of time and that it is advantageous for us as readers and critics to consider alternatives to progressive reality and linear discourse in order to comprehend many of Ambrose Bierce's stories, for his discourse is fluid and metonymic and defies explication within traditional western language concepts. The Hebraic theory of intertextuality encourages limitless considerations in textual analysis since language is perceived as a creative and dynamic force, not merely mimetic. As such it offers a means for reconsideration of fundamental theories concerning the natures of language and time in Bierce's stories.

Prediction of the Job Performance of Restaurant Workers Using a Service Orientation Measure

Description: Service orientation has been suggested to be a work-related behavioral trait that contributes toward overall job performance in certain occupations. Therefore, the Batrus Hollweg Service Questionnaire (SQ), a personality inventory, was hypothesized to predict performance in a sample (N=55) of fast-food restaurant workers whose jobs were primarily composed of service-related elements. A performance evaluation form was created for use as the criterion measure. An alternative scoring system for the SQ was developed, and showed it to be significantly correlated with the criterion. The potential for use of the alternative scoring procedure is discussed.
