Three unusual amino acids, y-amino-n-butyric acid, pipecolic acid, and 4-hydroxypipecolic acid, and an uncommon dipeptide, y-glutamyltyrosine, have been isolated and characterized from the seeds of members of the genus Sophora. Structural proof of these compounds was carried out by paper chromatography, thin-layer chromatography, column chromatography on amino acid analyzer, infrared, nuclear magnetic resonance, mass spectrometry, and C, H, N analysis. The presence and absence of these compounds was used as a criterion for the classification of 23 species of the genus Sophora. A phylogenetic classification which seems to follow the morphological taxonomy of this genus was carried out on the basis of seeds that contained pipecolic acid, those which did not contain pipecolic acid, and plants which contained both pipecolic acid and 4-hydroxypipecolic acids. Another chemical classification was also introduced based on the presence and absence of y-amino-n-butyric acid and y-glutamyltyrosine.

The genetic structure of 49 natural populations of four species (P. attwateri, P. boylii, P. pectoralis, and P. polius) of the Peromyscus boylii species group was analyzed through application of chromosomal and electrophoretic techniques. Chromosomal variation within and among populations of the boylii species group was analyzed from 178 specimens. Electrophoretic techniques were utilized for the demonstration of variation in enzymes and other proteins encoded by structural loci and applied to the study of the evolution of the boylii species group by estimation of levels of genetic heterozygosity within populations, estimation of degree of genetic similarity between conspecific populations and between species, and determination of patterns of geographic variation in allelic frequencies and levels of heterozygosity. Six distinct chromosomal patterns were observed among the populations of the four species of the boylii species group. All specimens had a diploid number of 48 and the major difference in chromosomal morphology was in the number of pairs of large to medium biarmed autosomes. Little or no chromosomal variation was observed in three species (attwateri, pectoralis and polius), but considerable chromosomal variation occurred among populations of P. boylii. Generally, the chromosomal variation in P. bylii was between allopatric populations, with each chromosomal pattern …

The problem of this study is the identification of differences in reading interests and preferences of Indian, Black, and white adolescents of both sexes and from different high school grade levels as they are related to (a) educational background of the parents, (b) availability of reading materials, (c) community size, and (d) the extent to which these preferences are represented in the standard selection aids for secondary school reading materials. A reading interest inventory was administered in the fall term, 1972, through English classes in twenty integrated schools in Oklahoma, representing three levels of population concentration. Community resources in reading materials available through school libraries, public libraries, and bookstores were evaluated. The reading inventories of 3,581 students were chosen to be evaluated to determine if there were significant differences at the .05 level. Earlier studies have indicated that sex and age are major factors in determining what teenagers read about and that adolescents' reading interests tended to be unique, personal, and very unpredictable.- Few studies have been reported that involved ethnic origin or family levels of education.

This study was conducted to investigate the relationship between the subtests of the Wechsler Intelligence Scale for Children (WISC) and the Illinois Test of Psycholinuistic Abilities (ITPA) and to investigate whether High Verbal-Low Performance (HV-LP) scorers on the WISC score significantly higher on certain ITPA subtests than High Performance-Low Verbal (HP-LV) scorers, and whether HP-LV scorers on the WISC score significantly higher on certain other subtests of the ITPA. Two main hypotheses were investigated in an effort to accomplish these purposes.

The first purpose of this study is to determine whether significant differences exist among the perceptions of principals, librarians, and teachers with respect to the following categorical practices or conditions relative to the learning-center concept in open-space elementary schools: (1) teacher preparation for use of the learning center; (2) student preparation for use of the learning center; (3) learning center personnel and their role; (4) operation of the learning center; (5) facilities, materials, and equipment in the learning center; (6) use of the learning center for individualizing learning; and (7) use of the learning center for developing independent learning skills. The second purpose of this study is to determine whether a significant correlation exists among specific categories. The third purpose of this study is to establish the degree of emphasis placed upon various practices or conditions relative to the learning-center concept in open-space elementary schools of Texas.

The problem with which this investigation is concerned is that of determining the procedures and methods elementary school principals in Texas utilized to implement the state-supported kindergarten program. A questionnaire was developed and content validity established by five authorities in the field of early childhood education. The questionnaire was forwarded to 100 randomly selected elementary school principals in Texas, and 94 percent returned the completed form. This study has a twofold purpose. The first is to describe the most frequently used procedures to implement the state-supported kindergarten program. The second is to identify those procedures used that are not educationally beneficial to young children to assist in statewide planning.

This investigation compares the results of three different methods of teaching tumbling, the Trampoline Method, Mental Practice, and the Traditional Method. The study also investigates whether sex and ability level significantly affect the results of the teaching methods. The subjects were the ninety members of the junior-level gymnastics classes for physical education majors at New Mexico State University during the fall and spring semesters of the 1972-1973 school year. There were forty-five female and fortyfive male subjects. A stratified random sample was constructed to insure equality of the teaching-method groups. The motor educability scores of the Johnson-Metheny Test were used to develop high-, medium-, and low-ability groups. The subjects in the ability groups were randomly selected and assigned to one of the teaching methods.

To obtain information regarding the effects of two divergent thought processes used in a college mathematics course for prospective elementary school teachers, this study compared the effectiveness of an adaptation of the traditional, deductive teaching method with that of an inductive method reflecting the recommendations of the Committee on the Undergraduate Program in Mathematics. In the spring semester of 1973, two sections of Mathematics for Elementary Teachers I, at Cameron College, Lawton, Oklahoma, served as experimental groups to test the two adaptations. The course followed the Committee on the Undergraduate Program in Mathematics recommendations for a first course in mathematics for prospective elementary teachers.

The problem with which this investigation is concerned is the effect of work-study method instruction upon the achievement of students in fifth grade social studies. The purpose of this investigation is to determine the effects of the SQ3R (Survey, Question, Read, Recite, Review) Study Method instruction upon the achievement of students in fifth grade social studies. The subjects ranged in age from ten years two months to thirteen years three months. Th I.Q. for the subjects ranged from 70 to 135. Of the 102 subjects involved in the study, 42 were male and 60 were female. The I.Q. score from the California Test of Mental Maturity, S Form was used to structure the subjects into three intelligence levels. Fifty-four subjects served as the experimental group, and forty-eight served as the control group. The instrument used to obtain pretest and posttest scores on the variable relating to achievement was the SRA Assessment Survey, Blue Level. Form E was used for the pretest, and Form F was used for the posttest. The subjects were assigned to four classes which were near equal. Two classes were selected by the principal to serve as the experimental group. The other two classes served as the …

The problem with which this investigation is concerned is that of making experimental measurements of proton-induced K-shell x-ray production cross sections and to study the dependence of these cross sections upon the energy of the incident proton. The measurements were made by detection of the characteristic x-rays emitted as a consequence of the ionization of the K-shell of the atom. The method for relating this characteristic x-ray emission to the x-ray production cross section is discussed in this work.

The problem with which this investigation is concerned is that of achieving reliability of administrative judgment in the selection of beginning teachers. This study has a threefold purpose. The first is to determine the type and extent of investigation necessary to achieve reliability of judgment in the ratings of teacher applicants. The second is to investigate the feasibility of a Regional Education Service Center's providing personnel selection services to independent school districts. The final purpose is to develop recommendations relating to reliability in teacher selection.

This study is concerned with the problem of analyzing the attitudes of the faculty and administration of North Texas State University. The purposes of this study are to describe the North Texas State University campus environment as perceived by the faculty and administration through responses to the CUES II questionnaire, and to compare selected subgroups of the faculty with regard to their perceptions of the campus environment. The questionnaire used in this study is the College and University Environment Scales: Second Edition. The questionnaire consists of 160 items or statements about facilities and conditions that may or may not be characteristic of a particular campus. There are seven different scores on the scales for the measurement of campus environmental characteristics. These scales are Practicality, Scholarship, Community, Awareness, Propriety, Campus Morale, and Quality of Teaching and Faculty-Student Relations.

The purpose of this study is to examine the extent to which fifth-grade teachers, teachers in special education, and child psychiatrists hold similar views regarding the seriousness of commonly observed student behaviors. In addition, the views of these three groups are compared to research regarding which behaviors in children are predictive of future delinquency. The Wickman Scale, consisting of fifty commonly observed children's behaviors, and a fifteen-pair Semantic Differential Scale, designed for use in this study, were administered to a group of fifth-grade teachers, a group of special education teachers, and a group of child psychiatrists.

The problem with which this investigation is concerned is that of determining the differential impact of informational delivery systems T1 (games and simulations), T2 (closed-circuit television), T3 (programmed learning), and T4 (standard lecture and discussion) on student understanding of elementary economic concepts as measured by the Test of Understanding in College Economics. In addition, the study seeks to determine whether a significant relationship exists between students' revealed preferences for specific informational delivery systems and increased economic understanding, and whether a significant relationship exists between students' evaluation of specific informational delivery systems as most effective in preparation for class examinations and increased economic understanding.

In the history of seventeenth-century European music the court of Christian IV (r. 1588-1648) occupies a position of prominence. Christian, eager for fame as a patron of the arts, drew to Denmark many of the musical giants of the age, among them the lutenist John Dowland and the composer Heinrich Schltz. Sadly, except for financial records and occasional letters still in the archives, few traces remain of these brilliant years in Denmark. The music composed and played during this half century has largely disappeared, most of it probably in the tragic fire of 1794 that destroyed the old Christiansborg Castle in Copenhagen and with it the court music archives. Except for the recently-discovered Clausholm Fragments, only three specimens of keyboard music from the period remain: Ny kgl. Saml. 1997 fol. (Obmaus Tablature), Gl. kgl. Saonl. 376 fol. (Copenhagen Tablature), and mu 6703.2131/6 (VoigtlaJnder Tablature). It has generally been assumed that the manuscripts were of German origin. The present study, however, demonstrates a probable Danish origin for the third, possible Danish connections for the second, and establishes that the first is of Austrian provenance. The Obmaus Tablature is an amateur's preservation of a German keyboard style already outdated. This slender manuscript, …

This study compares results of the six major forms of marriage counseling: individual interview, individual group, concurrent interview, concurrent group, conjoint interview, and conjoint group. Data are from five different approaches in research methodology. The first, termed the Pilot Study, reviewed the outcome records of 773 former marriage counseling clients. The second, termed the Experimental Study, assigned 63 couples on a random basis, although balanced for severity, to the three most popular forms of marriage counseling: concurrent interview, conjoint interview, or conjoint group. It included a pre- to post-counseling test comparison involving the MMPI, CPI, Polyfactor Test for Marital Difficulties, and the Marital Adjustment Inventory. The third approach, the Quasi-Experimental Study, compared test results from two groups of couples with serious marital problems: the first group comprised seven couples who had been in three forms of counseling, while the second group included twenty-one couples who had been in only one form. The fourth approach, the Survey Study, used a questionnaire to measure reactions of 200 subjects who had just completed various forms of marriage counseling sessions. The fifth approach, the Poll Study, involved a mail survey of 209 former marriage counseling clients who had been terminated from varying forms of …

The ancient artist's influences can still be felt in today's craftsmen. For example, the contemporary weaver Sheila Hick's prayer rugs are an assimulation of the textile techniques of ancient Peru, Persia, and India, and the macramed forms of the contemporary Spanish artist, Aurelis Munoz, are suggestive of the woven huts of many primitive cultures. Because of this influence upon the current investigation, the evolvement of weaving and its techniques, as well as the three-dimensional techniques of basketry, in different parts of the world and in different historical periods are reviewed briefly.

The objectives of the creative problem may be stated in two parts. First, the utilization of the self-portrait theme in order to explore a variety of drawing techniques, media combinations, and surface manipulations; and second, the maintenance of a sketchbook-diary which accompanies the study as supportive data. The sketchbook entries include not only pertinent visual material but also verbal commentary. The sketchbook-diary is sequential and denotes the various stages of development as well as the progression of the study.
