The purpose of this study was to develop information and understanding concerning the use of instructional resources, including library materials, by community junior college vocational-technical instructors.

Measurement of the line width parameters of a molecule is of interest because collision diameters can be calculated from them. This gives an effective size of the molecule when it is involved in interactions with other molecules. Further, specific types of interactions can be inferred from detailed information about the dependence of the line width upon pressure. In this paper, an experiment for measuring line width parameters for methyl cyanide is described and the results of the experiment are analyzed. This investigation was successful in obtaining precise values for the line width parameter for the J-J' = 0-1, J-J'= 1-2, and J-J' = 2-3 transitions of methyl cyanide which agree with experimental values of other researchers where available. It was found that standing waves were the dominant effect in the measurement of center frequency shift.

The problem of this study was to determine the criteria and procedures used by superintendents of selected public high schools districts in Texas in the selection of high school principals. This study had two main purposes : (1) to ascertain criteria and procedures that the superintendents of selected public school districts of Texas are using in the selection of high school principals, and (2) to make recommendations to improve the selecting of high school principals.

The problem with which this investigation is concerned is that of determining the effect of Biofeedback and/or Relaxation training on psycho-physical measures related to older persons' manifestations of stress. This is accomplished by assessing the differential outcomes obtained from using biofeedback plus relaxation with one group of subjects and relaxation training only with another group of subjects.

Methylgloxal synthase, which catalyzes the conversion of dihydroxyacetone phosphate to methylglyoxal and inorganic phosphate, has been found in several Enterobacteriaceae. The enzyme along with glyoxalase I and II and D-lactate oxidase, therefore, constitute a nonphosphorylated shunt of the normal glycolytic pathway

The problem of this study is differences in perceptions of priorities in selected areas of student teaching existing within the governance set, i.e., university directors of student teaching, public school administrators charged with implementing Senate Bill Eight, and presidents of local units of the Texas State Teachers Association. Six areas were chosen as the focal point of the study: selection of student teachers, selection of cooperating teachers, selection of college coordinators, placement of student teachers, evaluation of student teachers, and expenditure of Senate Bill Eight funds designated for the support of student teaching programs. The study concluded that the governance set is in overall agreement concerning the ordering of priorities. However, some significant differences were manifested concerning the implementation of specific priorities. Disagreements were noted in the following areas: selection body for student teachers, selection body for cooperating teachers, selection body for college coordinators, minimum grade point averages in education courses, and minimum grade point averages in major area courses.

The purpose of this study was to develop information and understanding concerning the use of instructional resources, including library materials, by community junior college vocational-technical instructors. The study sought to determine whether the kinds and amounts of instructional resources used by vocational technical instructors in their courses were related to their: (a) level of formal education, (b) number of courses in Higher Education completed, (c) years of teaching experience, and (d) teaching status (full or part-time). Further, the study sought to determine whether the attitudes toward use or non-use of the library were related to such instructor characteristics. The analyses of the data revealed that vocational technical instructors at Tarrant County Junior College utilized a wide variety of instructional resources in their courses. Instructional resources used in at least 50 percent of vocational-technical courses were: audio-visual materials, 88 percent; departmental books, 73 percent; personally owned books, 72 percent; manufacturers' literature other than service manuals, 63 percent; information from notes of previously taken courses, 63 percent; departmentally prepared syllabi, 58 percent; personally owned journals, 56 percent; self-prepared syllabi, 53 percent; manufacturers' service manuals, 52 percent; and association publications, 50 percent.

This dissertation reports research into the problem of how to teach mastery of the English writing system (MEWS) to students of English as a second language (ESL). The problem involves the relatedness of English orthography and phonology. The research had two purposes. First was development of classroom instructional materials for improving reading proficiency in ESL students by application of generative phonological principles. Second was use of the instructional materials in a pilot study of fifty-three ESL college freshmen. A major finding was that subjects' reading proficiency was far below that of native speakers at the college level. Another was that the subjects had more difficulty with English vowels than with consonants. The subjects' scores on nonsense-word tests correlated significantly with five other criteria, including measures of ability to use ESL. A uniform disparity between ESL-student and native-speaker scores on tests of nonsense words was identified. Native-speakers generally had perfect scores, and ESL students had low scores. A chief implication is the importance of understanding orthography in reading English. Recommendations are that ESL proficiency be determined by nonsense-word tests and that the MEWS program be used by students of English as a second dialect.

This study investigates the differences in receptive language of kindergarten children who are taught by different language systems. This study compares the effectiveness of the three most widely adopted oral language systems in the state of Texas. The systems used were (A) Alpha Time, (B) Beginning Readiness Kit; Beginning to Read, Write, and Listen Kits I and II, and (c) McMillan Series R, Bank Street, Threshold K. S. Analysis of variance techniques were used to analyze statistically pretest and posttest scores derived from the sample. The .05 level of significance was used throughout the statistical analyses for rejection or retention of the null hypotheses. Preliminary analysis of data determined no systematic bias for teacher variability or for within group variability. Hypotheses 1, 2, 3, and 5 were tested using a 2 x 3 analysis of covariance. The pretest was used as the covariant in this analysis. No statistically significant differences in the classroom mean scores were determined between teaching methods, teaching methods with only girls as subjects, teaching methods with only boys as subjects, and boys and girls. Hypothesis 4, concerning the pretest differences between boys and girls, was tested using a t-test for independent samples. No statistically significant differences …

Systematic desensitization and implosive therapy have surfaced as two of the primary behavioral therapy techniques to decrease phobic responses during the past decade. Although attempts have been made to compare the efficiency and effectiveness of these two techniques, results have been unclear because of the failure of researchers to duplicate the procedures as described by their respective originators. This experiment is designed to explore the joint effects of the therapies and level of therapeutic aspiration. A second objective, and a byproduct of the data produced in achieving the primary objective, was to analyze the goal discrepancy and attainment discrepancy scores accruing throughout the therapy sessions. Several hypotheses were advanced. Further analysis of the three criterion measures by means of ANOVA resulted in significant main sessions effects for each of the three independent analyses. Results suggest that all subjects, regardless of treatment subgroup, did make significant therapeutic gains in their approach scores, fear thermometer scores, and speed of approach scores from the first to the last session. Possible explanations for results were discussed. Furthermore, approach test absolute goal discrepancy, fear thermometer absolute goal discrepancy, approach test absolute attainment discrepancy, and fear thermometer absolute attainment discrepancy scores were calculated for all goal-setting …

The study then focuses on the Bernadotte candidacy as the practical expression of a Norwegian desire for a national monarchy. Reaction to the candidacy is analyzed and, although it proved unsuccessful, the strength of the idea is again evident when the government shifted its focus to the secondary candidacy of Denmark's Prince Carl. During the debate over the candidates for the throne, the underlying theme which developed was the question of Norway's form of government-- monarchy or republic.

In this study the choral-orchestral compositions produced by Hector Berlioz are examined in detail for characteristics of musical form, textual setting, and methods of scoring for chorus and orchestra. Reasons for the preponderance of the choral-orchestral medium in Berlioz' output are examined in two introductory chapters. The initial chapter concerns Berlioz' personal experiences as an observer, conductor, and critic of choral music, while the second is devoted to Parisian customs in regard to the choral-orchestral medium during the eighteenth and early nineteenth centuries. Included in the historical chapter is a discussion of the haute-contre (high tenor or countertenor) voice preferred in French choruses of that period plus a short review of French orchestral practices, operatic choruses, the French Chapel, Parisian concert societies, and the Paris Conservatory. Especially important is the segment on revolutionary musical fetes which fostered grandiose compositions for chorus and instruments of extremely simple structure. Berlioz' sense of form was governed by his Gallic heritage and for this reason many critics have accused him of formlessness, when in fact his compositions invaribly revolve around a succinct formal plan, admirably executed. Berlioz added to the conservative French tradition which favored the strophe and the Rondeau (an unvarying refrain following …

The problem of this study was to compare performances of college students given relaxation instructions and those not given those instructions on a paired-associate learning task. The results indicated that relaxation instructions alone produced a decrement in recall. When subjects received relaxation instructions as well as the suggestion that relaxation enhances learning, the decrement did not occur. Thus, situational demand characteristics appeared to be a significant variable in determining what effect relaxation instructions had on recall.

This problem was designed to evaluate the work performance change effected by each of three training programs; stepping, running, and bicycle ergometer riding. The study determined the specific work improvement of each training program by using a stress test designed from each of the training modes. Two of the purposes of the study were to determine the work performance effects and the specificity of training effect of each of the training procedures. The effect of body weight and leg strength were also measured in relation to performance, and the relative value of each of the three training procedures was evaluated. An analysis of the data showed that no training method was statistically superior to the others, but in order of improvement they ranked (1) bicycle ergometer riding, (2) stepping, and (3) running. Training by each method did appear to be specific to the type of work involved. In each method of training, the most significant improvement was in the work performance test related to that particular training procedure.

Thin target L-Shell x-ray production cross sections for protons incident on ₆₂Sm and ₇₀Yb in the energy range of 0.3 to 2.4 MeV/amu, alpha particles incident on ₆₂Sm, ₇₀Yb, and ₈₂Pb in the energy range of 0.15 to 4.8 MeV/amu, and lithium ions incident on ₅₈Ce, ₆₀Nd, ₆₂Sm, ₆₆Dy, ₆₇Ho, ₇₀Yb, and ₈₂Pb in the energy range of 0.8 to 4.4 MeV/amu have been measured. The cross section data have been compared to the planewave Born approximation (PWBA) and the PWBA modified to include binding energy and Coulomb deflection effects. The Lα₁,₂ x-ray production cross sections are best represented by the PWBA modified to include both the binding energy and Coulomb deflection effects (PWBA-BC) over the entire incident ion, incident energy, and target ranges studied. However, the Lγ₁ and Lγ₂,₃,₍₆₎ x-ray production cross sections are best represented by the PWBA except at the lower ion energies, where both the PWBA and PWBA-BC are in disagreement with the data. The comparison of Lα₁,₂/Lγ₂,₃,₍₆₎ ratios to theory reveals that the PWBA-BC does not predict the inflection point substantiated by the data, and the agreement between the data and the PWBA-BC becomes worse as the atomic number of the incident ion increases. Comparison …

This study examines the efforts of the Union and Confederate diplomatic agents to influence the events along the Rio Grande during the Civil War. The paper compares the successful accomplishments of Confederate agent Jose Quintero to the hindered maneuverings of the Union representatives, Leonard Pierce and M. M. Kimuey. Utilizing microfilmed sources from State Department records and Confederate despatches, the paper relates the steps Quintero took to secure the Confederate-Mexico border trade, obtain favorable responses from the various ruling parties in northern Mexico, and hamper the Union agents' attempts to quell the border trade.

Assertive training was investigated to determine its usefulness in teaching mildly retarded women to become more assertive. The 10 subjects (ages 18-35, WAIS VIQ 50-75) were randomly assigned to either the assertive training or the control group. Experimental subjects received 5 weeks of daily assertive training sessions which employed modeling, behavior rehearsal, and focused instructions in a group setting. Specific components of assertive behavior were taught in the following order: (a) assertive refusals, (b) assertive requests, (c) posture, (d) eye contact, and (e) loudness, Results of a behavioral role-playing task administered to both groups before and after treatment revealed that assertaive training subjects made significantly greater improvement than controls in their assertive content, Additionally, these subjects manifested significantly more improvement than control subjects on a global assertiveness measure.

This study investigated the perceptions of administrators of the YMCA and municipal recreation departments in the state of Texas concerning their cooperative relationship in the use of areas and facilities, personnel management, and program planning. A questionnaire was used to obtain their perceptions. Of the 140 questionnaires mailed, ninety-two were returned that were able to be utilized in the study. Their responses were analyzed using the Chi-Square test. The findings revealed a general agreement concerning the lack of cooperation between them. This wat evidenced in that they "never" or "seldom" communicated, consulted with the other, initiated joint sponsorship of programs, or cooperated in the three specified areas of recreational programming.

Annual energy budgets of dominant benthic macro-invertebrates were examined during November 1973 to October 1974 from the benthos of a small pond ecosystem in north-central Texas. Estimates of annual secondary production (Hynes and Coleman 1968) were Procladius s. (Diptera, Chironimidae), 2.4 g m^-2 y^-1 (13 kcal m^-2 y^-1 ); Tendipes decorus (Diptera, Chironomidae), 6.0 g m^-2 y^-1 (40 kcal m^-2 y^-1 ); Brachycercus sp. (Ephemeroptera, Caenidae), 1.9 g m^-2 y^-1 (11 kcal m^-2 y^-1). Energy metabolism was measured in the laboratory at six seasonally encountered temperatures (5, 10, 15, 20, 25, and 30 C) on an acclimatization basis, and then extrapolated to the field. Estimates of annual energy metabolism are Procladius sp., 5.0 kcal m^-2 y^-1 ; Tendipes decorus, 17.2 kcal m^-2 y^-1 ; Brachycercus sp. 40.0 kcal m^-2 y^-1.

One of the outgrowths of legislation enacted during the 1960's has been the deinstitutionalization of mentally retarded persons and the retention of others within the community. This study addressed the problem of nurses' perception of their competency to deal with this population wherever they might be encountered within community health care settings. The first hypothesis looked for differences in perceived competency based on the level of basic nursing education. Since sample sizes were not equal, the Kruskal Wallis test was utilized and a significant difference at the .001 alpha level was found. Hypothesis two looked for a relationship between perceived competency and degree of clinical contact with a mentally retarded population provided by the basic nursing preparation. Hypotheses three through six looked for relationships between perceived competency and adequacy of samples of content related to mental retardation provided by the basic nursing education: (1) risk factors; (2) etiology; (3) skills and techniques; (4) support systems. Hypothesis seven looked at the relationship between perception of competency and the adequacy of continuing education offerings to which nurses have been exposed. Hypothesis eight looked for a relationship between perceived competency and sustained personal contact with a mentally retarded person. A Pearson product moment …
