(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.

Actinide Production in the Reaction of Heavy Ions withCurium-248
Chemical experiments were performed to examine the usefulness of heavy ion transfer reactions in producing new, neutron-rich actinide nuclides. A general quasi-elastic to deep-inelastic mechanism is proposed, and the utility of this method as opposed to other methods (e.g. complete fusion) is discussed. The relative merits of various techniques of actinide target synthesis are discussed. A description is given of a target system designed to remove the large amounts of heat generated by the passage of a heavy ion beam through matter, thereby maximizing the beam intensity which can be safely used in an experiment. Also described is a general separation scheme for the actinide elements from protactinium (Z = 91) to mendelevium (Z = 101), and fast specific procedures for plutonium, americium and berkelium. The cross sections for the production of several nuclides from the bombardment of {sup 248}Cm with {sup 18}O, {sup 86}Kr and {sup 136}Xe projectiles at several energies near and below the Coulomb barrier were determined. The results are compared with yields from {sup 48}Ca and {sup 238}U bombardments of {sup 248}Cm. Simple extrapolation of the product yields into unknown regions of charge and mass indicates that the use of heavy ion transfer reactions to produce …

The Acute Effects of Intermittent Running on Serum CK and LDH Enzyme Activities in Runners and Non-Runners
Acute effects of repeated sprinting upon serum creatine kinase (CK), lactic dehydrogenase (LDH), and isozymal activities were studied in five collegiate runners (R_s) and six non-runners (NR_s ). After an intermittent running treadmill test, blood sampling showed three-fold mean increases in CK with no change in LDH in both groups; group differences were insignificant (p>.05). Results suggest (1) intense anaerobic exercise produces moderate enzyme elevations; (2) relatively equivalent exercise intensities are critical to enzyme responses in exercising individuals of varying fitness levels; and (3) exercise-induced enzyme release may be consequential to muscle cell membrane permeability changes from decreased intracellular high-energy phosphates.

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.

Algorithms of Schensted and Hillman-Grassl and Operations on Standard Bitableaux
In this thesis, we describe Schensted's algorithm for finding the length of a longest increasing subsequence of a finite sequence. Schensted's algorithm also constructs a bijection between permutations of the first N natural numbers and standard bitableaux of size N. We also describe the Hillman-Grassl algorithm which constructs a bijection between reverse plane partitions and the solutions in natural numbers of a linear equation involving hook lengths. Pascal programs and sample output for both algorithms appear in the appendix. In addition, we describe the operations on standard bitableaux corresponding to the operations of inverting and reversing permutations. Finally, we show that these operations generate the dihedral group D_4

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.

An Analysis of the Overt Teaching of the Monitor to Students of English as a Second Language
The overt teaching of the Monitor, or conscious rule awareness, to native Spanish-speaking ESL students was examined to note possible benefits to the students' oral English production. Native Spanish-speaking students of English (the experimental group) were taught an awareness of their ability to self-correct their spoken English. They were then compared to another group of native Spanish-speaking ESL students (the control group) in four areas: Ilyin Oral Interview score, total words produced, errors produced, and interference errors produced. The results of the study lend support to the theory that overt Monitor teaching could be beneficial to native Spanish-speaking students of English. The experimental group showed a significant gain in Ilyin scores and a significant reduction in the number of errors produced.

Appearance or Function: Factors Related to the Likeability of Handicapped Individuals
Descriptions of obesity, cerebral palsy, and scoliosis were rank-ordered (from one to twenty) and rated on a five-point scale by 75 college students. The descriptions were of two types: with the appearance of an individual on five levels of severity of a disorder and with the appearance and level of functioning of an individual on five levels of severity of a disorder. The ranking data indicated males rank-ordered descriptions of obese individuals different from cerebral palsy (p < 0.01) and scoliosis (p < 0.05) . The ratings of the descriptions were analyzed in two studies with 2 x 2 x 2 x 5 ANOVA's. Three-way interactions of the level of severity, complexity of description, and type of disorder rated were discussed in terms of likeability of handicapped individuals .

Artistic Vibrato and Tremolo: A Survey of the Literature
This investigation surveys pertinent literature, from 1917 to 1982 inclusive, regarding artistic vibrato and tremolo in singing. The contents are subdivided into individual investigative reports by various vocal researchers. Due to mounting confusion within the amassed literature, the need for systematic organization and evaluation is evident. Misunderstandings within the context of the literature and misnomers within the terminology require clarification and resolution. The evaluation intends to produce a proper perspective on vibrato and tremolo, eradicating some of the confusion surrounding the terms. Artistic vibrato is recognized as a desirable component in Western vocal music. In contrast, tremolo is deemed a deviant vibrato, i.e., a vibrato which deviates from artistic norms. The study attempts to clarify the distinguishing traits of these two vocal phenomena.

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.
