This dissertation is concerned with the relationship between the trumpet and organ in twentieth-century music for this ensemble and how that relationship effects performance with regard to organ registration and synchronization. The compositions discussed include "The Other Voices of the Trumpet," by Daniel Pinkham (1971); "Jericho: Battle Music," by William Albright (1976); "Three Pictures of Satan," by Jere Hutcheson (1975); and "Okna," by Petr Eben (1980). The theoretical writings of Pierre Boulez, Robert Erickson, and Donald Cogan deal with developing a contemporary concept of texture. This dissertation applies their theory that texture exists in two dimensions: vertical and horizontal. Stratification and blending of timbres comprise the vertical dimension. The succession of textures, governed by tempo, creates the second dimension. Chapter I provides an historical setting for the genre, introduces the theory of Boulez, Erickson, and Cogan, and supplies the programmatic content of the four works chosen for analysis. In Chapter II , the vertical elements of texture in these four works are isolated and examined. Chapter III deals with Pierre Boulez's theory that the succession of textures, governed by tempo, shapes the work. Each work is examined with regard to tempo, either mobile (fluctuating) or fixed. In Chapter IV the …

This study investigated the interactions of facially deformed infants (FD) with their mothers compared to a facially nondeformed control group (FND). All mother-infant dyads were videotaped for 10 minutes during a free play period. Mothers were instructed to spend time with their baby as they normally would. The videotaped interactions of 14 FD dyads and 14 FND dyads were rated by five raters for quality of interactions, amount of vocalization, touch, and face-to-face gaze. The infants were rated on their level of attractiveness from polaroid pictures and videotapes. Mothers also completed a questionnaire which assessed their infants' temperament. Three of the studies' four hypotheses were confirmed. First, the more attractive an infant was, the better his/her interactions with the mother were judged to be. Second, FD infant dyads were rated as significantly poorer in quality of interaction than FND dyads, although FD* dyads did not spend significantly less time vocalizing, touching, or in face-to-face gaze as predicted. A significantly higher percentage of FD infants were judged as having difficult temperament relative to FND infants. Finally, as predicted it was found that infants with difficult temperaments were more likely to exhibit poorer quality interactions than infants with less difficult temperaments. These …

The purpose of this research was to develop an empirical model which could be used to predict job tenure for sewing machine operators in a large garment factory. Although the model did accurately predict tenure in each of five scoring ranges, the results did not meet the level of significance set forth in the hypothesis. It can be fairly stated that the results were trending in the right direction, but were not statistically significant.

This lecture-recital deals with the two percussion sextets of Carlos Chavez. Each of the compositions is analyzed by examining compositional characteristics and performance problems. The selection, substitution, and construction of the necessary instruments for performance are explored. Suggestions for stage set-up are also included. The percussion ensemble has become an integral part of most high school and university percussion programs. Much of the literature composed for this medium has not become part of the standard literature. Chlvez's Toccata has obtained its place in the literature—it is one of the most often performed percussion works in the world. Although Tambuco has not yet attained the same status as Toccata, it is, nevertheless, an important contribution to the literature. An attempt is also made to identify the significance of these works by examining some of the early influences on Chavez's compositional style both from his native Mexico, and from other composers writing for percussion ensembles.

This study is concerned with the problem of whether the public's attitudes toward economic well-being could be compared with the types of television programs made popular over a thirty-year period. Two measures were used to determine the public's attitudes toward economic well-being: 1) answers to questions of an economic nature; and 2) answers to questions that asked what was the most important problem. All data were compiled from Gallup polls administered during 1955 through 1984. The television genre data were compiled from sources by Brooks and Marsh, McNeil and Norback and Broadcasting magazine. No association existed among the three measures.

The energy states of C₃ᵥ symmetric top polyatomic molecules were studied. Both classical and quantum mechanical methods have been used to introduce the energy states of polyatomic molecules. Also, it is shown that the vibration-rotation spectra of polyatomic molecules in the ground and excited vibrational states can be predicted by group theory. A comprehensive model for predicting rotational frequency components in various v₁₀ vibrational levels of propyne was developed by using perturbation theory and those results were compared with other formulas for C₃ᵥ symmetric top molecules. The v₁₀=1,2,3 and ground rotational spectra of propyne in the frequency range 17-70 GHz have been reassigned by using the derived comprehensive model. The v₁₀=3 and v₁₀=4 rotational spectra of propyne have been investigated in the 70 GHz, and 17 to 52 GHz regions, respectively, and these spectral components assigned using the comprehensive model. Molecular constants for these vibrationally excited states have been determined from more than 100 observed rotational transitions. From these experimentally observed components and a model based upon first principles for C₃ᵥ symmetry molecules, rotational constants have been expressed in a form which enables one to predict rotational components for vibrational levels for propyne up to v₁₀=5. This comprehensive model also …

Incident 0.5 to 2.5 MeV charged particle beams were used to ionize the inner-shells of selected targets and study their subsequent emission of characteristic x-rays. ⁹Be⁺ ions were used to examine K-shell x-ray production from thin F, Na, Al, Si, P, Cl, and K targets, L-shell x-ray production from thin Cu, An, Ge, Br, Zr and Ag targets, and M-shell x-ray production from thin Pr, Nd, Eu, Dy, Ho, Hf, W, Au, Pb and Bi targets. L-shell x-ray production cross sections were also measured for ²⁷Al⁺ ions incident upon Ni, Cu, Zn, As, Zr, and Pd targets. M-shell x-ray production cross sections were measure for ²⁷Al⁺ and ⁴⁰Ar⁺ ions incident upon Pr, Nd, Gd, Dy, Lu, Hf, Au, Pb, Bi, and U targets. These measurements were performed using the 2.5 MV Van de Graaff accelerator at North Texas State University. The x-rays were detected with a Si(Li) detector whose efficiency was determined by fitting a theoretical photon absorption curve to experimentally measure values. The x-ray yields were normalized to the simultaneously measured Rutherford backscattered (RBS) yields which resulted in an x-ray production cross section per incident ion. The RBS spectrum was obtained using a standard surface barrier detector calibrated for …

Protons with energies ranging from 0.4 to 2.0 MeV were used to measure K-shell vacancy production cross sections (oVK) for N_2, CH_4, C_2H_4, C_2H_6, and CO_2 gas targets under single collision conditions. An electron-ion time-of-flight coincidence technique was used to determind the ration of the K-K electron capture cross section, OECK, to the K-vacancy production cross section, oVK. These ratios were then combined with the measured values of oVK to extract the K-K electron capture cross sections. Measurements were also made for protons of the same energy range but with regard to L-shell vacancy production and L-K electron capture for Ar targets. In addition, K-K electron capture cross sections were measured for 1.0 to 2.0 Mev 42He^_ ions on CH_4.

The purpose of this study was to determine the effectiveness of a transitional first grade program. A comparison of reading and math achievement and school attitude was the focus of the study. The study utilized a pretest/posttest design. The group of regular first grade students who qualified for the transitional program but attended regular first grade was the control group. The group of transitional first grade students was the experimental group. The regular first grade students received formal instruction in all academic areas. The experimental group received no formal instruction. All students were pretested and posttested using the Iowa Test of Basic Skills and the Minnesota School Attitude Survey. Testing was administered to small groups of five or less by the researcher. Scoring was done also by the researcher. An analysis of covariance was used to determine if a significant difference existed between the groups. The analysis of covariance did not produce a significant F at the .05 level when applied to the Iowa Test of Basic Skills except for reading for boys in both groups. The numbers in each cell were low and no further comparisons were made. Due to a testing date that was approved late in the …

Utilizing shift/share and economic base analysis, data covering employment, income, and population are analyzed for each of the nine regions of the United States as defined by the Census Bureau. The study covers 1970 through 1984 because widespread redistribution of employment and a shift toward more service-oriented, white collar jobs occurred during this period. This study presents currents trends and recommends ways in which people may better prepare for the future.

Absolute K-shell x-ray cross sections and Auger-electron cross sections are measured for carbon for 0.6 to 2.0 MeV proton incident on CH₄, n-C₄H₁₀ (n-Butane), i-C₄H₁₀ (isobutane), C₆H₆ (Benzene), C₂H₂ (Acetylene), CO and CO₂. Carbon K-shell fluorescence yields are calculated from the measurements of x-ray and Auger-electron cross sections. X-ray cross sections are measured using a variable geometry end window proportional counter. An alternate method is described for the measurement of the transmission of the proportional counter window. Auger electrons are detected by using a constant transmission energy Π/4 parallel pi ate electrostatic analyzer. Absolute carbon K-shell x-ray cross sections for CH₄ are compared to the known results of Khan et al. (1965). Auger-electron cross sections for proton impact on CH₄ are compared to the known experimental values of RΦdbro et al. (1979), and to the theoretical predictions of the first Born and ECPSSR. The data is in good agreement with both the first Born and ECPSSR, and within our experimental uncertainties with the measurements of RΦdbro et al. The x-ray cross sections, Auger-electron cross sections and fluorescence yields are plotted as a function of the Pauling charge, and show significant variations. These changes in the x-ray cross sections are compared …

Respiratory and metabolic patterns in response to variations in exercise workload (WL) and pedal frequency (RPM) were examined in 10 healthy males. Each subject performed WLs of low (L), moderate (M) and high (H) intensity, equivalent to 25%, 50% and 75% V02 m a x at 7 pedal frequencies (40, 50, 60, 70, 80, 90 and 100 RPM). ANOVA ( 3 X 7 design) indicated that WL and RPM had independent and significant effects on all respiratory and metabolic measures; i.e., the greater the WL and RPM, the higher the HR, V02, VC02, Ve, Fb, Vt, Vt/Ti, Vt/Te and Ti/TtQt and the lower the Ti and Te. However, analysis of the interaction effect revealed different response patterns for Fb, Vt, Ti, Vt/Ti, Vt/Te and Ve among the WLs. During L-WL, increases in RPM produced increases in Ve which were due to progressive increases in both Fb and Vt. However, during M-WL and H-WL, increases in RPM produced increases in Ve which were accomplished by a constant Vt and a progressive increase in Fb. My findings suggest that during low WLs, the signal for Vt is dependent on rate of contraction, while during M-WL and H-WL, the signal for Vt appears …

This study attempted to explore the strength and nature of relationships between specific intellectual information processing skills included in a multi-dimensional model conceived by Guilford, and measured by Meeker's Structure of Intellect - Learning Abilities Test, and specific musical aural discrimination skills as measured by Gordon's Musical Aptitude Profile. Three research questions were posed, which involved determining the strength and the nature of the relationship between MAP melodic, rhythmic, and aesthetic discrimination abilities and the intellectual information processing skills comprising the SOI - LA. Both instruments were administered to 387 fourth, fifth, and sixth graders from schools in the Dallas area. After a pilot study established the feasibility of the study and reliability estimates of the test instruments, multiple regression analysis determined that 10% to 15% of the variance between intellectual information-processing skills and the individual musical aural discrimination abilities was in common (r = +.32 to r = +.39). It was further determined that only six specific SOI intellectual dimensions, all involving the skills of "Cognition" and "Evaluation", were significantly related to the musical aural discrimination abilities. Through the use of the Coefficient of Partial Correlation, the strength of each individual information-processing skill's unique contribution to that covariance was …

The muscarinic agonist carbachol stimulates a rapid increase in ^32Pi incorporation into phosphatidic acid (PA) and phosphatidylinositol (PI) in calcium tolerant myocytes prepared from heart tissue. The density of muscarinic receptors, determined by [^3H]-QNB binding, is greater in the atria than in the ventricles. 250 uM carbachol decreased specific [^3H]-QNB binding to muscarinic receptors on myocyte membranes by fifty percent. Trifluoperazine, also a phospholipase C inhibitor, inhibited the carbachol stimulated increase in ^32Pi incorporation into PA and PI and did not interfere with muscarinic receptor binding. Therefore, isolated canine myocytes provide a suitable model system to further study the muscarinic receptor stimulated phospholipid effect, and its role in mediating biochemical processes and physiological function in the heart.

The purpose for choosing this study was to compare the perceptions of the role of presidents in teachers colleges in Northeastern Thailand. The study groups included the presidents, the administrative staff, and the teaching faculty within these colleges.

This study examines nursing students' adoption of inferential sets in a clinical situation. The investigation determines (1) the particular inferential set(s) nursing students adopt toward a patient in a clinical situation; (2) the particular inferential set(s) adopted by sophomore and senior nursing students in a clinical situation; and (3) whether or not inferential sets adopted by the sophomore and senior nursing students differ. Sophomore and senior nursing students at a woman's university in Texas were asked to complete a research tool designed to determine inferential set adoption.

The purpose of this study was three-fold: 1. To determine the amount and direction of changes in sources of funding for the Regional Education Service Centers from 1979 to 1984. 2. To determine the percent of change in programming expenditures of the Regional Education Service Centers from 1979 to 1984. 3. To rate the changes in quality of programming as perceived by the superintendents of the local school districts receiving services from 1979 to 1984. A review of the literature and a brief history of the Regional Education Service Centers of Texas were followed by tabular and narrative descriptions of the findings. Deflated data, to account for inflation, were derived by applying Bureau of Labor statistics formulas to dollar amounts supplied by the Regional Education Service Centers. Each of the five Education Service Centers included in the study experienced a decrease in total funds, due chiefly to a cut in federal and state support. Although local contributions increased in four out of five of the Regions during the five-year period, the net result to the Centers was a decrease in funding ranging from 23.2 percent to 51.8 percent. The impact on programming was severe. Of the nine major services on …

Baroreflex function and cardiovascular responses to lower body negative pressure during selective autonomic blockade were evaluated in endurance exercise trained (ET) and untrained (UT) men. Baroreflex function was evaluated using a progressive intravenous infusion of phenylephrine HCL (PE) to a maximum of 0.12 mg/min. Heart rate, arterial blood pressure, cardiac output and forearm blood flow were measured at each infusion rate of PE. The reduction in forearm blood flow and concomitant rise in forearm vascular resistance was the same for each subject group. However, the heart rate decreases per unit increase of systolic or mean blood pressure were significantly (P<.05) less in the ET subjects (0.91 ± 0.30 versus 1.62 ± 0.28 for UT). During progressive lower body negative pressure with no drug intervention, the ET subjects had a significantly (P<.05) greater fall in systolic blood pressure (33.8 ± 4.8 torr versus 16.7 ± 3.9 torr). However, the change in forearm blood flow or resistance was not significantly different between groups. Blockade of parasympathetic receptors with atropine (0.04 mg/kg) eliminated the differences in response to lower body negative pressure. Blockade of cardiac sympathetic receptors with metoprolol (0.02 mg/kg) did not affect the differences observed during the control test. It was …

The purpose of the present study was to determine if psychological stress, defined as academic examination stress, would systematically produce changes in immune parameters (immunoglobulin concentration) and psychological functioning. It was hypothesized that as examination stress occurred there would be an effect on immunological function consistent with heightened psychological activity/stress. Subjects were 23 master's and doctoral students in psychology who volunteered for the research project. All subjects were administered a series of psychological tests to measure stress, personality factors, emotional states, and anxiety levels. All tests were administered and.blood samples drawn over a period of 15 months across two lowstress and two high-stress periods. Immunological tests included white blood cell (WBC) differential count and radial immunodiffusion (RID) for the determination of concentration of different immunoglobulin classes (IgA, IgG, IgM) in serum. Data were treated to a one-way analysis of variance (ANOVA) with repeated measures, t /test for correlated samples correlational matrix between variables across assessments and discriminant function analysis. Results showed (1) increased immunoglobulin levels during periods of stress; (2) immunoglobulin G most consistently related to stress and probably most indicative of the stressed condition and biological resistance to stress; (3) anxiety related to external events; (4) increase in anxiety …

Efforts were made to (1) enumerate and isolate the intestinal bacteria of Ascaris suum; (2) identify those bacteria isolated; and (3) assess the ability of intestinal bacteria to produce serotonin.

The problem with which this investigation was concerned was that of the use of parents as therapeutic agents. The purpose of this study was twofold. The first was to determine the effect of filial therapy on parental acceptance, self-esteem, parent-child relationship, and family environment. A second was to analyze the results and make recommendations concerning the effectiveness of filial therapy as a treatment modality for parents and their children. The experimental design of the study was a nonrandomized, pretest-posttest, control group design.The sample (N=47) consisted of the experimental group (parents N=15, children N=9) who received filial therapy and the control group (parents N=12, children N=ll) who did not. The treatment included ten, two hour weekly parent training sessions. During these sessions the parents were taught the principles of client-centered play therapy and were instructed to conduct weekly one-half hour play sessions at home with their own children. Based on the findings of this study, the following conclusions were drawn: 1) Filial therapy does significantly increase the parents' feeling of unconditional love for their children and 2) Filial therapy does significantly increase the parents' perception of expressed conflict in their family. In addition to the statistically significant results, there were some …

This descriptive study with quantitative aspects examined the phenomenon of elder abuse through the systematic review of 60 cases of elder abuse. Cases were randomly selected from the files of an Adult Protective Services agency in the North Central Texas area. Research questions examined the characteristics of the victims and abusers, types and duration of abuse, descriptions of abusive situations, the reporting and verification of abuse, case management strategies utilized by caseworkers, and the consequences of those strategies. The results of this study point to the probability of the elderly abuse victim being 75 years of age or older, female, white, and widowed. There did appear to be some connection between race and type of abuse with white victims more likely to experience physical and financial abuse. Approximately half of the elderly abuse victims had severe limitations in physical and/or mental functioning leading to some degree of dependence upon their abusers. However, eighty percent of the elderly victims resided in their own homes and half of these individuals were functionally independent. This study provided descriptions of the various types of abuse that were observed: physical, financial, emotional, passive neglect, and active neglect. Financial abuse was noted most frequently, and multiple …

The problem of this study was the roles of the general assembly agencies of the Presbyterian Church in the U.S.A., the Presbyterian Church in the U.S., and the United Presbyterian Church of North America in the development of Barber- Scotia College, Knoxville College, Johnson C. Smith University, Stillman College, and Mary Holmes College. The historical records of these three churches for the period from 1866 to 1983 were examined to analyze the factors surrounding the establishment of the five colleges, the differences and similarities in the administrative practices of the general assembly agencies charged with operating the colleges, the relationships of the colleges to the churches in the transition from dependent mission schools to independent colleges, and to identify way in which the Presbyterian Church (U.S.A.) may improve its support of Black higher education. The Presbyterian Churches established the mission schools to meet the religious, educational, and economical needs of the emancipated Black slaves. Though the three 2 churches had differences over the issues of slavery and doctrine, the administrative systems developed for the operations of the schools were very similar. All treated the missions schools as remedial temporary measures necessitated by the refusal of Southern and border states to …

The psychological characteristics of programmers are believed to be important determinants of programming productivity. However, little evidence is available to support this contention. This investigation, motivated by the lack of such evidence, was concerned with determining the influence of the programmer's cognitive complexity (differentiation and integration) and experience on comprehending and modifying programs of different levels of complexity. Data were collected from ninty-three graduate and undergraduate students in a classroom experimental setting. In the first phase of the experiment, a background questionnaire was administered in order to collect experience and other demographic information. Also, a domain-specific Role Construct Repertory (REP) Test was administered to collect cognitive complexity information. In the second phase, the subjects were randomly assigned to either the program comprehension group or to the program modification group. Both groups used two COBOL programs of differing levels of complexity to do comprehension and modification exercises. Three sets of hypotheses were tested. The first set of hypotheses was designed to evaluate the direction and strength of the relationship between cognitive complexity and program comprehension and modification. The second set of hypotheses was designed to evaluate the combined influence of cognitive complexity and program complexity on the comprehension and modification of …
