(4+2)-Cycloaddition Reactions of Ketenes; Pyranones
This study deals with the (4+2)-cycloaddition reactions of 4-Ï€ electron compounds with ketenes. Chloroketenes were generated in situ from the corresponding chlorinated acid chlorides in the presence of the ketenophiles. Chloro-, dichloro- and diphenylketenes reacted with 1-methoxy-3-trimethylsiloxy-l,3-butadiene, and 2,4-bis(trimethylsiloxy)-1,3-pentadiene to yield the corresponding dihydropyrans. The dihydropyrans yielded substituted 4-pyranones on hydrolysis.

Algebraic Numbers and Topologically Equivalent Measures
A set-theoretical point of view to study algebraic numbers has been introduced. We extend a result of Navarro-Bermudez concerning shift invariant measures in the Cantor space which are topologically equivalent to shift invariant measures which correspond to some algebraic integers. It is known that any transcendental numbers and rational numbers in the unit interval are not binomial. We proved that there are algebraic numbers of degree greater than two so that they are binomial numbers. Algebraic integers of degree 2 are proved not to be binomial numbers. A few compositive relations having to do with algebraic numbers on the unit interval have been studied; for instance, rationally related, integrally related, binomially related, B1-related relations. A formula between binomial numbers and binomial coefficients has been stated. A generalized algebraic equation related to topologically equivalent measures has also been stated.

An Analysis of Audit Risk in Associating with Reserve Information of Oil and Gas Companies
This research was designed to investigate the relationship between audit risk and the conduct of the audit engagement in the specific context of an oil and gas audit. Because reserve estimates are in the financial reports of oil and gas entities (in the depreciation, depletion and amortization calculation, the limitation on capitalized costs for companies using the full-cost method, and the required supplementary disclosure for companies subject to Securities and Exchange Commission requirements) and because the reserve estimation process is considerably affected by numerous factors, there is a chance that a material error could be incorporated into the financial statement representations with which the auditor is associated. The objective of the research was to (1) identify conditions which are important in an assessment of audit risk in associating with reserve estimates, and (2) determine the impact of some of these conditions on the conduct of the audit.

An Analysis of Classroom Management Procedures Utilized by Teachers of Emotionally Disturbed Students
The teacher of the emotionally disturbed student must provide an educational setting for pupils unable, or unwilling, to appropriately interact within the regular educational setting. The teacher, ultimately, decides classroom scheduling, academic experiences, social interactions and order of the room. In short, teaching style and the teaching personality shape the learning environment. Style of teaching is evidenced by the management techniques utilized within the classroom. The purpose of this study is to determine if differences exist in the classroom management techniques employed by educators of emotionally disturbed children and youth assigned to (a) resource rooms in the public school setting, (b) self-contained classrooms in the public school setting, and (c) residential treatment centers as determined by the Classroom Management Profile (Bullock & Zagar, 1980).

An Analysis of Factors Related to Texas Public School Nurses' Delivery of Health Services to Handicapped Children
This study investigated the factors related to the delivery of health care services by school nurses. The purposes of the study were divided into three categories. The first was the nurses' identification of the handicapping conditions of children in their caseloads and their perceptions of the children's health problems. The second involved data about the nurses' educational background and preparation they felt as useful in their work with children with handicaps; data on barriers which limit or prevent nursing care of these children was also solicited. Third, information was sought about future plans of nurses for obtaining more education, barriers perceived which hindered their plans, and special considerations in program planning that would facilitate their educational goals. Institutional guidelines were written based on findings of the study and the review of literature.

An Analysis of Perceptions of Teacher Effectiveness
The study was designed to determine and compare the perceptions of various groups with regard to the most and the last important characteristics and behaviors of effective teachers. The population for the study included (a) four groups of high school graduates selected at five year intervals beginning with 1980, (b) four groups of high school dropouts selected from the same five year intervals, (c) high school teachers, (d) high school principals and central office administrators, and (f) teacher educators. The instrument used to determine perceptions was a 28 item Q-sort. The items of the Q-sort were developed from a review of the literature on teacher effectiveness and from a review of the criteria for the evaluation of teacher effectiveness as used by the school district in which the study was conducted. The Q-sort items were deemed valid by a panel of teacher educators.

An Analysis of the Impact of a Behavioral Style Awareness Training Program on Retail Sales Effectiveness of Commission Sales Personnel in a Major Department Store Chain in the Southwest
The success of any retail institution depends upon many factors including personal selling effectiveness. Traditional sales training has focused primarily on the selling process with emphasis on how to close a sale. The idea of using behavioral style awareness training with salespeople has emerged only recently when behavioral training began to be recognized in the literature as a tool for sales training as well as for management training. The Social Style of Behavior concept developed by Dr. David Merrill was selected for use in this research study. Utilizing this concept, a behavioral style awareness training program was developed involving twenty hours of classroom training. Training methods used were lecture, role play, and videotaped materials with emphasis on behavioral identification and using versatility with applications to personal selling in a retail situation.

Assessment of Visual Memory and Learning by Selective Reminding
A test of free recall visual memory and learning was developed for the present study. The purpose of the study was to determine the utility of the Visual Selective Reminding Test and the Verbal Selective Reminding Test for differentiating among groups of patients having memory impairments with organic etiologies. It was hypothesized that neurologically impaired patients would perform differently on the Visual and Verbal Selective Reminding Tests, the difference depending on the location of the underlying brain damage. Forty right handed male patients at a Veterans Administration hospital served as subjects. The patients were grouped according to the location of their brain damage; left hemisphere, right hemisphere, diffuse damage, and no brain damage. There were 10 patients in each group. Each patient was given the verbal and the visual memory tests in counterbalanced order and the Shipley estimate of intelligence.

Attitudes and Treatment Knowledge by Medical Students Regarding Rape Victims
The purpose of this study was to investigate the attitudes and treatment knowledge of medical student professionals regarding rape victims. In addition to generating normative data for a population which, as a function of their vocation may come in contact with victims, comparisons were made between a sample of those beginning their medical education process and those at the end of training in order to measure change in treatment knowledge and attitudes towards rape victims which occur during medical school. Also investigated were differences which exist in the attitude and treatment knowledge measures for rape victims compared to other emergency room patient populations, and the effect of gender of the physician upon those measures. A final element investigated the physicians' perceptions of a "real" rape as it relates to those measures.

Attitudes of Vocational Teacher Education Majors in the United States Toward Sex-Role Expectations in Regard to the Dual-Income Financial Support of the Family
The purpose of this study was to identify differences in attitudes of vocational teacher education majors based on age, sex, marital status, earner status, educational level, vocational program area, mother's work history, and familial attitudes. Data for the study were obtained from 1,182 vocational teacher education majors. The more contemporary attitudes were held by those who were female, aged 26 - 35, currently members of dual-income families, graduate students, identified as homemaking education majors, from families whose mothers had worked outside the home when they were growing up, and who were not brought up to believe that a woman's place is in the home.While females had more contemporary attitudes than males, both could be described as having moderate attitudes toward the dual-income financial support of the family. Both females and males felt that women should contribute financially to the support of the family, that it is just as important for a woman to be able to earn a living as it is for a man, and that women should expect to be permanent members of the labor force.

Bureaucratic Orientations as Related to the Need Fulfillment Deficiencies of Teachers in a Medium Size School District in Texas
The purpose of this study was to determine the direction and strength of the relationships that exist among teachers between bureaucratic orientation (the criterion) and each of the five human need variables that include security, social, esteem, autonomy, self—actualization, and four demographic factors that include sex, experience, educational level, and age. This study was also concerned with determining if the bureaucratic orientation of teachers is affected by deficiencies in their human needs and by their demographic differences. Determination of these relationships was accomplished by using an intercorrelation matrix of product-moment correlations and stepwise multiple regression.

The Cognitive Development Sequence of Music Skills in Elementary School Aged Children
The problem of this study was to determine the cognitive development sequence of music skills. This sequence was determined by finding the music skills level, the Piagetian developmental level, and the developmental art level for twelve students differing in reading ability and in the first through fourth grades.The students were individually tested, using Piaget's semi-clinical interview technique. The students were tested on seven Piagetian tasks, ten music tasks, and one art task. The validity was determined through the interview process. The examiner redirected questions until he was certain the subjects were responding from conviction. The reliability of the study was achieved through a test-retest procedure and impartial expert evaluation of the test sessions.

A Comparison of Adjunct Computer-Assisted Instruction and Traditional Instruction for Teaching Counseling Theories
This study examined differences in achievement over Person- Centered Therapy and Rational-Emotive Therapy taught by adjunct computer-assisted instruction tutorials (CAI) and traditional instruction (TI). The Achievement Instrument Over Person-Centered Therapy and Rational-Emotive Therapy was developed by the researcher to measure achievement. Content validity and test-retest reliability were established for the test. Analysis of covariance was utilized to test for differences in achievement gains between the CAI and TI groups. Cumulative university grade point averages and achievement pre-test scores were covariates. The Kolmogorov-Smirnov test was used to determine if the distribution of scores following instruction would be more positively skewed for the CAI group than for the TI group. This effect was expected if CAI was more effective than TI for low ability students.
