The Study of Low Temperature Silene Generation

Description: The reactions of tert-butyl-, sec-butyl-, and n-butyllithium with dimethylfluorovinylsilane include addition to the double bond to give both silene and silenoid intermediates, fluorine substitution, and a novel vinyl substitution. For the tert-butyllithium reaction, product stereochemistry and trapping experiments using both cyclopentadiene and methoxytrimethylsilane show that silenes are not formed in THF. In hexane about 67% of the 1,3-disilacyclobutanes obtained arise from silene dimerization while 33% are formed by silenoid coupling. In hexane the order of reactivity for addition, t-Bu > sec-Bu > n-Bu, is opposite that for fluorine substitution. The vinyl substitution is most significant with secondary alkyllithium reagents including the tert-butyllithium adduct to dimethylfluorovinylsilane and with sec-butyllithium itself. Evidence for the formation of vinyllithium or ethylene in the process could not be obtained.

Childbirth and Locus of Control: The Role of Perceived Control in the Choice and Utilization of Birthing Alternatives

Description: The purpose of this study was to determine whether the wives' perceptions of personal control over the process of childbirth were related to couples' choices and utilization of three birthing alternatives (home birth, unmedicated hospital birth, and medicated hospital birth). The wives' perceived control over the childbirth process was expected to vary inversely with the level of medical intervention in the birthing alternative chosen. The home birth mothers were expected to perceive themselves as having more control over childbirth than were the unmedicated hospital group mothers, and the unmedicated hospital group mothers more than the medicated hospital group mothers. The husbands' perception of their wives' perceived control in childbirth and their participation was also measured.

Major Spelling Deficiencies Among Collegiate Business Students

Description: The problem of this study was an analysis of major spelling deficiencies among collegiate business students. The purposes were as follows: (1) to develop a diagnostic instrument that will measure spelling deficiencies; and (2) to make recommendations regarding the preparation of materials that will assist students in overcoming these deficiencies. Written assignments prepared by collegiate Business Communication students were examined for spelling errors. Errors were then classified into the following categories: (1) words with "ie" and "ei" ; (2) final "e"; (3) final consonant rule; (4) final "y"; (5) confusion over vowel sounds; (6) pronunciation problems; (7) sound-alikes; (8) plurals; (9) apostrophes; (10) omissions; (11) additions and repetitions; (12) substitutions; (13) demons; and (14) miscellaneous. Percentages of total errors served as a guideline for preparation of a Table of Specifications, and a Spelling Diagnostic Test was developed. Validity of the instrument was determined by a panel of experts. The test was then administered to 214 collegiate business students, and a reliability coefficient of .83 was determined using the split-half method.

Sexual Function in Women Following Treatment for Cervical Dysplasia and Microinvasive Cervical Carcinoma

Description: One hundred women aged 20 to 50 were asked to compare their sexual experience before diagnosis and following treatment for benign and malignant cervical disease. The subjects were divided into five groups: three groups had definite cervical intraepithelial neoplasia (CIN), (Class II or III). Two groups were treated with cryotherapy, and one with hysterectomy. One group had a provisional diagnosis of CIN I, but received no treatment. Subjects in the last group had microinvasive cervical carcinoma and were also treated with hysterectomy. All subjects had ovarian function; all were sexually active at the time of treatment. They were interviewed at least six months post-cryotherapy and 15 months post-hysterectomy. All subjects completed a variant version of the Derogatis Sexual Function Inventory (DSFI).

Degradation of Humic Substances by Aquatic Bacteria

Description: A variety of aquatic bacteria were isolated and tested for their ability to degrade humic substances and their aromatic residues/monomers which serve as precursors of the trihalomethanes (THMs) found in chlorinated drinking waters. The majority of them were Gram-negative, oxidative types dominated by pseudomonads. Most of the 146 isolates were found to utilize as their sole source of carbon several or more of ten aromatic compounds known to be products of degradation of humus and also to be precursors of THMs. The aromatics tested, with percent of the isolates utilizing the compound in parentheses, were: p-hydroxybenzoate (49), vanillic acid (48), 3,5-dihydroxybenzoic acid (16), syringic acid (19), vanillin (30), benzoic acid (27), ferulic acid (34), resorcinol (9), catechol (8) and protocatechuic acid (27).

Public School Teaching and Administrative Employment Applications in Texas: A Study of Compliance with and Awareness of the Civil Rights Acts of 1964 as Amended in 1972, and Equal Employment Opportunity Commission Policies and Regulations

Description: The purpose of this study was to determine whether application forms used in Texas public schools for teachers and administrators were in compliance with federal Equal Employment Opportunity Commission (EEOC) and Texas Human Rights Commission Act (THRCA) regulations regarding preemployment practices. Participating in the study were 740 public school districts in Texas. The study also attempted to determine if these application forms are in violation of EEOC regulations pertaining to pre-employment practices and whether classification based on the districts' size, wealth, student ethnicity and geographical location has a bearing on the degree of compliance with and awareness of EEOC and THRCA regulations. A model employment application form and set of guidelines were developed for school districts to use in securing pre-employment information. Inferential statistics were used through various applicable designs. Three different types of analysis were utilized. These were a Descriptive Analysis, a Goodman- Kruskal Gamma (y) Coefficient—chi-square analysis and a Multiple Regression analysis. The descriptive analysis included the calculation of percentages of the suspect questions appearing on teacher and administrator application forms utilizing the Criteria Used to Determine EEO Compliance and Awareness Among Texas School Districts. The Goodman-Kruskal Gamma (y) Coefficient and the chi-square analysis were employed in order to determine differences in compliance and awareness based on the districts' size, wealth, student ethnicity and geographical location. The GAMTAU. ASC Computer Program was used to test the Gamma values, with a standard z-score. The Multiple Regression analysis was employed to determine to what extent variation in the use of total suspect questions correlated with size, wealth, ethnicity and geographical location. The results of the data analyzed reveal that the size and ethnicity of the school district had a weak but significant correlation with EEO compliance and awareness based on employment application forms for teachers and administrators and that school ...

An Investigation of the Career Realities and Occupational Concerns of Selected Professional Performing Musicians

Description: The purpose was to investigate the career realities and occupational concerns of successful full-time performing instrumentalists. Four research problems were formulated; (1) the establishment of a demographic profile of musicians who perceived themselves successful; (2) the determination of the musicians' career realities; (3) the determination of the musicians' occupational concerns; and (4) a comparison of the relationship of the demographic profile to the career realities and occupational concerns. A pilot study was used to develop a questionnaire and an interview schedule. The sample for the main study was chosen by the questionnaire and consisted of twenty musicians, five each in the musical categories of jazz, classical, commercial and pop. To resolve research problem one, the questionnaire also collected general demographic data. Research problems two and three were fulfilled by an interview schedule based upon career realities and occupational concerns cited in previous sociological studies. The realities and concerns were either confirmed or refuted by each interviewee. The career realities were role conflict, career contingencies, musical labels, life style, hierarchies, audience relationships and environment. The occupational concerns were mobility, status, entrapment, personal contacts, dependency, security, competition, economic issues, working conditions, travel requirements, appearance, management control, auditions, maintenance of skills and training relevancy. The interviews were taped and transcribed by a court reporter and included in the text. An analysis of the interviews in relation to the demographic data fulfilled research problem four. Results showed that career contingencies, mobility and life style were positive influences for the sampled musicians. Also, a "hierarchy of expertise" appeared as the ultimate occupational hierarchy for the sampled musicians. Furthermore, a "hierarchy of dependency," based upon instrument played, affected the sampled musicians' attitudes toward their careers. It was concluded that performers who were devoting their full time to performance were more tolerant of imperfect career conditions than ...

The Use of Learning Theory in the Application of Artificial Intelligence to Computer-Assisted Instruction of Physics

Description: It was the purpose of this research, to develop and test an artificially intelligent, learner-based, computer-assisted physics tutor. The resulting expert system is named ARPHY, an acronym for ARtificially intelligent PHYsics tutor. The research was conducted in two phases. In the first phase of the research, the system was constructed using Ausubel's advance organizer as a guiding learning theory. The content of accelerated motion was encoded into this organizer after sub-classification according to the learning types identified by Gagnds. The measurement of the student's level of learning was accomplished through the development of questioning strategies based upon Bloom's taxonomy of educational objectives. The second phase of this research consisted of the testing of ARPHY. Volunteers from four levels of first-semester physics classes at North Texas State University were instructed that their goal was to solve three complex physics problems related to accelerated motion. The only students initially instructed by ARPHY were from the class of physics majors. When the threshold values of the pedagogical parameters stabilized, indicating the fact that ARPHY's instructional technique had adapted to the class' learning style, students from other classes were tutored. Nine of the ten students correctly solved the three problems after being tutored for an average of 116 minutes. ARPHY's pedagogical parameters stabilized after 6.3 students. The remaining students, each from a different class, were tutored, allowing ARPHY to self-improve, resulting in a new tutorial strategy after each session. It is recommended that future research into intelligent tutoring systems for science incorporate the principles and theories of learning which this research was based upon. An authoring system based upon the control structure of ARPHY should be developed, since the modular design of this system will allow any field which can be organized into a net-archy of problems, principles, and concepts, to be tutored.

Religious Inventory for the Assessment of Psychologically Healthy and Unhealthy Beliefs

Description: The problem concerns determining whether healthy and unhealthy religious beliefs can be distinguished. A 150 item Religious Beliefs Inventory (RBI) was developed to assess healthy and unhealthy religious beliefs. In a pilot study, RBI scales were developed and the MMPI-168 was used as the criteria measure. Fifteen of the 23 RBI scales yielded an average reliability of .79 and an average validity of .48 for 95 undergraduate university subjects. The present study seeks to cross-validate the results of the pilot study with a church-active sample. Six judges/pastors evaluated RBI items as healthy or unhealthy and their responses were used to formulate and validate the RBI scoring system. For the 196 church-active subjects, Hypothesis 1 is supported by eleven of the seventeen significant predicted correlations between the RBI and the validity criteria MMPI- 168, ranging from .14 to .28 with an average of .20. The average reliability of 15 RBI scales is .71. Hypothesis 2 is supported by five of eight significant predicted positive correlations between the RBI and the Rehfisch RI (Rigidity) scale, ranging from .18 to .25 with an average of .17. One or more of the following explanations may account for the absence of higher and more numerous significant correlations for support for Hypotheses 1 and 2 found in the present study: (a) the distribution of scores on 18 of 24 RBI scales are skewed to the right; (b) there are significant differences between characteristics of the pilot study undergraduate sample and the church-active sample participating in the present study; (c) there is a need to assess an individual's degree of involvement in his religious beliefs; (d) psychometric improvements are needed in the RBI; and (e) limitations of the validity criteria. In conclusion, although the RBI is not ready for clinical use, fifteen of the RBI scales appear ...

The Relationship Between Mood Elevation and Attribution Change in the Reduction of Depression

Description: This study investigated the relationship between the depressive attributional style described by Beck and Seligman and elevation of mood. It was proposed that mood elevation would reduce the level of depression and, in addition, would reduce the number of negative attributions. The reduction of negative attributions was assumed to be a more cognitively mediated process and was proposed to occur subsequent to mood change. These assumptions are contrary to the current cognitive theories of depression and attribution which view attributional style as a prerequisite to both the development and reduction of depression. Subjects were 30 undergraduate students between the ages of 19 and 40 years old who volunteered to participate in the study. They were screened on the basis of demonstrated depression (13 and above on the Beck Inventory) and susceptibility to hypnosis (high susceptibility on the Harvard Group Scale of Hypnotic Susceptibility) . Subjects were randcmly assigned to one of three groups; (1) hypnosis with mood elevation, (2) hypnosis with relaxation, and (3) no treatment control. The results supported the hypothesis that mood elevation would reduce level of depression. The mood elevation group demonstrated a lowering of depression. The effects of the treatment procedure did not appear until the fourth session. As anticipated, reduction in negative attributions did not precede or coincide with reduction in depression. It was not possible to determine the change in the attributional style of subject during the time period of this study. The results were discussed in terms of Bower's Associative Network Theory in which activation of mood facilitates the access to memories, behaviors, and interpretation of events which are congruent with the mood state.

The Effects of Computer Assisted Instruction on the Development of Reading and Language Skills

Description: This research investigates the effects of a planned program of computer assisted instruction on reading and language development of fourth grade students. The purpose of the study was to determine the effectiveness of microcomputer usage in supplemental reading and language instruction. Fifty-one matched pairs of fourth graders completed the one school year study. A t test for related samples was used to analyze the data. Multiple linear regression was used to allow a more detailed review of the basic data, including gender and entering ability. The findings include the following. 1. Post test scores for total reading or total language on the Comprehensive Test of Basic Skills of the experimental group did not differ significantly from the scores of the control group. 2. The incremental differences in the post test scores for the boys or the girls in the experimental group did not differ significantly from those of the boys or the girls in the control group in either reading or language. 3. For students starting lower, toward the middle or higher on the Comprehensive Test of Basic Skills total reading or total language, the relative progress of the experimental group of any of the three groups did not differ significantly from those of the control groups. The general conclusion to be drawn from this study is that using prescribed software for thirty minutes a week did not significantly improve total reading or total language scores on the Comprehensive Test of Basic Skills. This study also indicates no significant differential effects on entering ability or gender. These recommendations were made. 1. More weekly computer time be utilized in further research. 2. Further evaluation of software as it relates to basic classroom curriculum for all levels of achievement should be studied. 3. Further study should be conducted on gender as it ...

A Content Analysis of Public Broadcasting Service Television Programming

Description: The problem with which this investigation is concerned is the description of the social map that is presented to the viewers of public television. Using content analysis methodology, the study describes how different genders, racial groups, and age groups are being portrayed on PBS programming. The sample consisted of one week of PBS 1984 fall programming broadcast on KERA-TV, the PBS station in Dallas-Ft. Worth, Texas. Research questions addressing proportions of groups, types of roles, length of scenes, occupational variation, conversational behaviors, conflict management modes, and cultural norms were answered. All coding was accomplished by the principal investigator. Upon completion of the coding sub-totals for the variables under study by program types and a grand total for the entire sample were then tabulated. After this extensive content analysis, the report concludes that females are still extremely underrepresented in PBS programming, accounting for only 32.7% of the total participants. Blacks and Hispanics are also underrepresented except in children's programming. Occupational variation for white males is evident for all types of PBS programming. Occupational variation for white females is evident in children's programming and informational/documentary programming. Minorities with delineated occupations are extremely limited in all types of programming except for children's programming. The exchange of information is the major conversational behavior that occurs on PBS programming with minority characters receiving orders considerably more than their white counterparts. Verbal aggression is the conflict management mode chosen most frequently on PBS programming. Explicit messages regarding racial and sexual equality and prosocial behavior occur on PBS programming. Implicit messages such as frequency of appearances, number of major roles, and prevalence of power cues suggest a white male domination of television programming on PBS. The findings of the study reveal that major inroads have been made by women and minorities in children's programming. This comprehensive analysis ...

The Premenstrual Syndrome: Daily Stress and Coping Style

Description: The premenstrual syndrome (PMS) continues to be an enigma for many: those women who report PMS, for professionals who attempt to treat premenstrual symptoms, and for researchers attempting to identify PMS and to compare treatments. The present study investigated the responses from 86 subjects between the ages 30-45 for their perceptions of daily stress and coping styles by PMS level. Three levels of PMS were formulated by subject responses to the questionnaire (a) PMS for scores within the criteria, (b) Non-PMS for scores lower than the criteria, and (c) Psy-Non-PMS for certain scores higher than the criteria with a psychological, or neurotic, profile. Hassle intensity (daily stress) and coping style, whether problem-focused (P) or emotion-focused (E), were assessed by questionnaire. In addition, help seeking behavior, i.e., whether a woman sought help from a doctor in the past twelve months, was examined but did not significantly relate to level of PMS, hassle intensity, or coping style. Psy-Non-PMS women reported perceiving significantly more hassles and significantly greater use of four of the E coping styles, Detachment, Focusing on the Positive, Self-blame, and Keep to Self, than the Non-PMS women. PMS women endorsed perception of significantly more hassles and significantly greater use of two of the E coping styles, Detachment and Keep to Self, than the Non-PMS women. These E coping styles are consonant with detached, avoidant, escapist, and self-deriding coping mechanisms, typical of depressed and anxious persons. There was some difficulty in differentiating the PMS group from the Psy-Non-PMS group. Only one coping style, Focusing on the Positive, was endorsed by the Psy-Non-PMS group significantly more than the PMS group. Further statistical analysis of the data could determine psychological/behavioral PMS subtypes as distinct from physiological PMS subtypes, providing more clearly defined PMS groups. Future research involving a carefully controlled study for determining ...

Symphony No. 1 "Concertante"

Description: Symphony No. 1 "Concertante" is a work of approximately twenty-two minutes duration for chamber orchestra. The work is scored for flute (doubling piccolo), oboe (doubling English horn), B-flat clarinet, bassoon, trumpet, F horn, trombone, tuba, percussion, harp, piano (doubling celesta), solo violin, solo viola, solo cello, solo double bass, and strings.The percussion battery, which is to be played by one performer, includes three timpani, vibraphone, orchestra bells, xylophone, chimes, suspended cymbal, bass drum, snare drum, and two triangles. One group of instruments, including the eight winds, percussion, and the four solo strings, is treated primarily in a soloistic manner although it also functions as a part of the ensemble. The remaining group, piano, harp, and strings, functions primarily as an accompanying group although it does get some soloistic treatment. The work is in four movements, each of which uses the traditional symphonic form. Movement I is in sonata-allegro form, movement II a simple ternary "song" form, movement III a scherzo and trio, and the final movement is a theme and variations. These traditional forms apply only to thematic use and development, however, for the tonal scheme is developed in a broader design which unfolds throughout the course of the four movements. All important melodic ideas are based on the same pitch set that serves as the basis for the tonal scheme.

Cognitive Coping Strategies with Chronic Back Pain Patients

Description: Low back pain has long been estimated to be the most prevalent and debilitating source of chronic pain. The present study first reviews the literature addressing the various theories of pain, the physiological and psychological variables important in pain research, and the psychotherapeutic approaches that have been used to date to reduce pain. Thirty-seven hospitalized chronic back pain patients were administered the cold-pressor test and a medical pain stimulus procedure which was medically relevant to their back pathology. A card-sort method was utilized in order to assess the coping strategies employed by the patients during these two pain stimulus tasks. These procedures were repeated following treatment. Coping strategies used by patients during the two pain tasks were compared. Results demonstrated that there was a significant difference in the manner in which patients coped with the two types of pain. Cold-pressor measures of pain threshold and tolerance were not significantly different between pretreatment and post-treatment. These measures were also not positively correlated with treatment outcome. A multiple regression approach demonstrated that particular coping strategies were significantly predictive of treatment outcome. The medical pain stimulus procedure was found to provide more significant pedictor variables than the cold-pressor test. At pre-treatment assessment, patients who relied on dramatized coping strategies were less likely to be successful in treatment. Breathing activity and pain acknowledgement were positive coping techniques highly predictive of successful outcome in this study. The use of computers for assessment and other recommendations for future research were discussed.

A Comparison of the Effectiveness of Childbirth Preparatory Techniques

Description: Stress reduction techniques have been used to assist people in coping with stressful medical procedures and events. Labor and delivery training classes have utilized techniques to assist women with the childbirth process. The classes generally included basic education of labor and delivery, respiration behavior, relaxation of muscles, and participation of a coach. Reducing the amount of pain experienced in labor and delivery has been suggested for facilitating the process and decreasing the amount of medication received. The painful experience changed from an uncontrollable situation into a positive one, allowing women to feel more resourceful, less anxious, and less threatened.

An Exploratory Study of Curiosity in Three-, Four- and Five-Year-Old Children

Description: This study investigated the development of curiosity in young children. A previous study by Kreitler, Zigler, and Kreitler had identified five specific types of curiosity, manipulatory curiosity, perceptual curiosity, conceptual curiosity, curiosity about the complex, and adjustive-reactive curiosity. The basic problem was to describe the development of these five types of curiosity in three-, four-, and five-year-old children. A secondary problem was to determine if children follow a predictable pattern in their development of the five types of curiosity. Five tasks, measuring nineteen variables of curiosity, were administered individually to thirty three-year-olds, thirty four-year-olds, and thirty five-year-olds by a trained rater. Mean scores for each variable and each type of curiosity were calculated for each group.

Uniformed Military Counselors: Effects of Counselor Attire on Potential Client Initial Perceptions and Preferences

Description: This study was undertaken to investigate the influence of a military counselor s attire on potential clients expressed perceptions of and preferences for a counselor. Ninety volunteer participants were selected from a large southwestern Air Force base. Participants ranged in age from 18 to 46 years, with 68 male and 22 female volunteers. Rank was divided into 69 enlisted personnel (56 males and 13 females) and 21 officers (12 males and 9 females). Three videotapes were made depicting a counselor in three attire conditions: civilian; military officer; and military enlisted. A pilot study was completed which validated the research assumption that the videotapes differed only in the counselor's attire conditions. Participants were randomly assigned to three treatment groups. After each group was shown a videotape portraying the counselor in one of the three attire conditions, the participants were administered the Counselor Rating Form and the Referral Questionaire. The Counselor Rating Form is composed of three scales which assess perceptions of a counselors' trustworthiness, attractiveness, and expertness. The Referral Questionaire assesses subjects preferences to see a specific counselor in the event counseling is desired. Two main hypotheses, each having three subhypotheses, were developed for the study. The first hypothesis compared participants reactions to a counselor in civilian and military attire conditions. The second hypothesis compared participants' reactions to a counselor in two military attire conditions representing officer and enlisted ranks. Data was analyzed by analysis of variance procedures, with Scheffe' methods used, when appropriate, for multiple comparisons of mean scores.

Some Responses of Bacillus subtilis Spores to Glutaraldehyde

Description: Bacillus subtilis (ATCC 19659) were damaged by exposure to various concentrations of glutaraldehyde, as shown by decreased germination rates. The damage caused was repaired or otherwise obviated by the presence of sodium lactate in the holding medium. When two different salts of lactic acid were compared for ability to overcome the effect of glutaraldehyde, it was found that calcium salt of lactate was more effective than the sodium salt. The damage repair system involved l-alanine, lactate and either the sodium or calcium ions. The study involved in determining the difference in efficiency of spore repair was due to an organic or an amino acii snowed that the presence of two carboxylic functional groups did not effectively alter the reactivity.

Self-Perception of Health: A Proposed Explanatory Model and a Test of its Clinical Significance

Description: A multivariate model of health self-perceptions was postulated based upon a comprehensive set of health related variables suggested by previous bivariate research. Components of the model included measures of health attitudes, health practices, health locus of control, a measure of stress/ coping, and a physical health measure. A stratified random sampling technique was used to select 10 8 subjects based upon the external measure of physical health which included categories ranging from disability-severe to symptom free-high energy level. All subjects completed a health questionnaire comprised of measures of the model components, two measures of health self-perceptions, and the Health Resource Task, an author designed instrument measuring a subject's ability to generate flexible health alternatives/resources. Bivariate correlational analysis revealed that the physical health, stress/coping, health practices, and locus of control measures and certain of the health attitude subscales were significantly correlated to general health self-ratings. A multivariate model including these variables accounted for almost 50 percent of the variance in one of the general health self-ratings measures and approximately 38 percent of the variance in the Health Resource Task. Suggestions for refining the proposed model were made.
