References to Trumpet Music in the Battle Chansons of Clement Janequin

This paper is an examination of the battle chansons of Clement Janequin for references to Renaissance trumpet music. The following issues are addressed: dating the early use of the clarino register; the history and evolution of the courtly trumpet ensemble; and the transition from the shorter trumpet of the Middle Ages to the longer instrument of the middle Renaissance and Baroque eras. Because the earliest Janequin battle chanson predates all known written trumpet sources by over fifty years, musical evidence gleaned from these battle chansons can help to establish the existence and character of trumpet performance practices in the first third of the sixteenth century. The first chapter summarizes all of the known primary sources of information on Renaissance trumpet performance, and identifies important issues worthy of further investigation. The second chapter examines trumpet music and trumpet style in the Renaissance, including trumpet ensemble performance, military trumpet calls, and the imitation of trumpet style in purely vocal music, and contains eight musical examples. The third chapter discusses the battle chansons of Janequin and their influence on other sixteenth-century works. Chapter £our analyzes the battle works of Janequin for allusions to trumpet music and includes eleven musical examples. The fifth and …

Selected Contemporary Performance Problems as Found in Karel Husa's Sonata No. 2 for Piano (open access)

Selected Contemporary Performance Problems as Found in Karel Husa's Sonata No. 2 for Piano

The purpose of this study is to identify some of the performance problems associated with contemporary piano music, using the Sonata No. 2 for Piano by Karel Husa (1921 - ) as the basis for the discussion. In so doing, this study identifies Karel Husa as an important contributor to twentieth century piano repertoire. Personal interviews and correspondence with the composer provided biographical, analytical, and stylistic insight for this study. Supplemental information on Karel Husa was obtained from journals, newspaper articles, and dissertations. The first chapter provides biographical information gleaned from the interview, with emphasis on Husa's keyboard compositions and early compositional influences. The second chapter offers a detailed formal analysis of the Sonata No. 2 from the perspective of motivlc development and cyclic unity. The final three chapters focus on twentieth century performance problems as exemplified in Karel Husa's Sonata No. 2 for Piano. In Chapter 3, the discussion of notation provides a general background on notational developments in pitch and rhythm in the twentieth century, with the Sonata illustrating these procedures. The fourth chapter concentrates specifically on Husa's individual rhythmic language. The final chapter is devoted to Husa's coloristic use of the piano, addressing his unique contributions to …

Parental Cultural Mistrust, Background Variables, and Attitudes Toward Seeking Mental Health Services for Their Children (open access)

Parental Cultural Mistrust, Background Variables, and Attitudes Toward Seeking Mental Health Services for Their Children

Attitudes toward mental illness and the willingness to seek psychological treatment for their children among ethnic minority group parents were investigated. Participants consisted of black, Hispanic, Native American and Asian parents. All parents were given the Terrell and Terrell Cultural Mistrust Inventory, Cohen and Struening Opinions About Mental Illness Scale, Reid-Gundlach Social Services Satisfaction Scale, Fischer-Turner Attitudes Toward Seeking Professional Help Scale, and Ahluwalia Parents' Psychological Help-Seeking Inventory. A multiple regression model was used to explore the purpose of this study. Parental mistrust level, ethnicity, education, income level, and opinions about mental illness served as predictor variables. The criterion variables consisted of scores on the Social Services Satisfaction Scale and Attitudes Toward Seeking Professional Psychological Help Scale. The results indicated that the most significant predictor of psychological help-seeking was parental cultural mistrust level. Parents with higher cultural mistrust levels were less likely to seek help. Education was also predictive of black and Native American parents' help-seeking attitude and willingness to seek psychological help for their children. Black and Native Americans with lower levels of education were less willing to seek treatment for their children than members of those ethnic groups with higher levels of education. Ethnicity was also related to …

Critical Expectations of Workers Undergoing a Major Change in the Workplace (open access)

Critical Expectations of Workers Undergoing a Major Change in the Workplace

In an effort to determine whether job satisfaction and expectations in a group of workers undergoing major change in the workplace differ from groups of workers not undergoing major change, data were collected from three groups of workers at the operator level in a major U.S. electronics manufacturing company. Two of the groups were not undergoing a major work redesign and served as control groups. A group undergoing the early stages of a major work redesign, characterized primarily by their formation into a self-managed work team, served as the experimental group. The experimental group and one control group were located at the same manufacturing plant, while the other control group was located at another plant. It was hypothesized that the group of workers undergoing change would differ in job satisfaction and that over time, the difference would grow. It was also hypothesized that the group undergoing change would have different expectations about the nature of their jobs in the future. Data were collected from members of the three groups using a modified version of Hackman and Oldham's (1980) Job Diagnostic Survey, with two administrations of the survey seven months apart. Data were analyzed using a 3 (Groups) X 2 (Perception: …

Assessment of the Effects of Communication Training on the Adult Elderly and the Assisting Adult Child (open access)

Assessment of the Effects of Communication Training on the Adult Elderly and the Assisting Adult Child

This study examined the effects of Systematic Training for Effective Parenting (STEP) on affection, communication, and relationship between elderly parents and their assisting adult children. Twenty-eight pairs of parents and children were randomly assigned to treatment or control groups. Subjects took Quinn's Family Life Questionnaire as pre-, post-, and follow-up tests. Parents and children in the treatment groups attended a four-session STEP workshop. No significant differences were found on the 2 x 2 analysis of variance for repeated measures for the parents or adult children. Quinn's affection and relationship variables approached significance for the parents over time. His variable affection approached significance for the children over time, irrespective of group. Agreement approached significance for children in the treatment group. The results for the parents regarding affection suggest that the study may have emphasized their feelings of trust. Although the data for relationship approached significance, it was negative, indicating that parents in the treatment group may have reduced their interaction with their assisting children perhaps because they were learning new communication skills. The data for the children regarding affection approached significance, but it was negative, suggesting they felt free to question their feelings about themselves and their parents. The results for …

Uniqueness of Positive Solutions for Elliptic Dirichlet Problems (open access)

Uniqueness of Positive Solutions for Elliptic Dirichlet Problems

In this paper we consider the question of uniqueness of positive solutions for Dirichlet problems of the form - Δ u(x)= g(λ,u(x)) in B, u(x) = 0 on ϑB, where A is the Laplace operator, B is the unit ball in RˆN, and A>0. We show that if g(λ,u)=uˆ(N+2)/(N-2) + λ, that is g has "critical growth", then large positive solutions are unique. We also prove uniqueness of large solutions when g(λ,u)=A f(u) with f(0) < 0, f "superlinear" and monotone. We use a number of methods from nonlinear functional analysis such as variational identities, Sturm comparison theorems and methods of order. We also present a regularity result on linear elliptic equation where a coefficient has critical growth.

The Analysis of PCDD and PCDF Emissions from the Cofiring of Densified Refuse Derived Fuel and Coal (open access)

The Analysis of PCDD and PCDF Emissions from the Cofiring of Densified Refuse Derived Fuel and Coal

The United States leads the world in per capita production of Municipal Solid Waste (MSW), generating approximately 200 million tons per year. By 2000 A.D. the US EPA predicts a 20% rise in these numbers. Currently the major strategies of MSW disposal are (i) landfill and (ii) incineration. The amount of landfill space in the US is on a rapid decline. There are -10,000 landfill sites in the country, of which only 65-70% are still in use. The Office of Technology Assessment (OTA) predicts an 80% landfill closure rate in the next 20 years. The development of a viable energy resource from MSW, in the form of densified Refuse Derived Fuel (dRDF), provides solutions to the problems of MSW generation and fossil fuel depletions. Every 2 tons of MSW yields approximately 1 ton of dRDF. Each ton of dRDF has an energy equivalent of more than two barrels of oil. At current production rates the US is "throwing away" over 200,000,000 barrels of oil a year. In order to be considered a truly viable product dRDF must be extensively studied; in terms of it's cost of production, it's combustion properties, and it's potential for environmental pollution.

Effect of Task Appropriateness, Social Comparison, and Feedback on Female Goals, Performance, and Self-Confidence with a Motor Task (open access)

Effect of Task Appropriateness, Social Comparison, and Feedback on Female Goals, Performance, and Self-Confidence with a Motor Task

Lenney (1977) concluded that achievement gender differences were predicted by females' lower self confidence and expectancies in competitive situations, identifying three variables that mediated female self confidence in achievement situations, (1) task appropriateness. (2) social comparison, and (3) feedback. The present study manipulated all three mediating variables with 240 undergraduate 18-25 year old female subjects with the pursuit rotor task that requires tracking a moving (40 rpm's) white light with a hand-held stylus for 60 seconds. Response measurement was based upon time on target. Subjects were tested over five trials while setting goals for each trial. Females were randomly assigned to a male appropriate, female appropriate, or gender neutral task condition, a competition or alone condition, and to one of four feedback conditions (no feedback, feedback about own performance only, feedback about own performance that provided the perception that subject was performing better than an opponent and/or average on each trial, or feedback about own performance that provided the perception that subject was performing poorer than an opponent and/or average on each of the five trials). Results from the 2 (social comparison) X 3 (task appropriateness) X 4 (feedback) ANOVA were contradictory to previous findings (Corbin, 1981; Petruzzello & Corbin, …

Opioid/Adrenergic Interaction in Regulating Canine Cardiac Function (open access)

Opioid/Adrenergic Interaction in Regulating Canine Cardiac Function

Opioid/adrenergic interactions were studied to evaluate two hypotheses: (1) naloxone potentiates the effect of epinephrine on cardiac contractility by increasing circulating epinephrine concentrations; and (2) endogenous and exogenous opioids alter left cardiac nerve stimulationinduced norepinephrine release and cardiac function. A canine isolated heart-lung preparation was used for the first study. Plasma epinephrine was determined and myocardial epinephrine uptake was calculated during intravenous epinephrine infusion. Naloxone (4 mg) was given and the epinephrine infusion was repeated. Naloxone increased cardiac contractility, coronary blood flow, and the coronary sinus epinephrine concentration. When coronary blood flow was subsequently held constant (100% above resting), naloxone increased only contractility. This result indicated that the previously observed increase in coronary sinus epinephrine was flow dependent. Corticosterone (an uptake II blocker) was employed as a positive control. Corticosterone increased the contractile response to epinephrine, but unlike naloxone, corticosterone was accompanied by a clear decrease in myocardial epinephrine uptake. The stereospecificity of the response to naloxone was investigated and (+) naloxone equaled or exceeded (-) naloxone in potentiating the inotropic effect of epinephrine. In the second study, the left cardiac nerve was isolated and electrically stimulated in intact dogs. Norepinephrine overflow gradually declined during successive control stimulations.

A Time Series Analysis of the Functional Performance of the United States Supreme Court (open access)

A Time Series Analysis of the Functional Performance of the United States Supreme Court

The focus of this investigation is the relationship of the United States Supreme Court's functional performance to its environment. Three functions of courts are noted in the literature: conflict resolution, social control and administration. These functions are operationalized for the United States Supreme Court. Hypotheses are developed relative to the general performance of these three functions by all courts. Box-Jenkins time series analysis is then used to test these hypotheses in relation to the performance of the United States Supreme Court. The primary analysis rests upon a data set that includes all non-unanimous decisions of the Supreme Court from 1916 to 1986. A supplemental analysis is conducted using all formal decisions for the 1953 to 1986 period. The results suggest that intellectual resources, legal resources, modernization, and court discretion are significant influences on the functional performance of the United States Supreme Court. Future research must consider these influences in the development of a general theory of courts.

Exploratory and Confirmatory Factor Analysis of the Clinical Scales of the Luria-Nebraska Neuropsychological Test Battery, Form II (open access)

Exploratory and Confirmatory Factor Analysis of the Clinical Scales of the Luria-Nebraska Neuropsychological Test Battery, Form II

The factor structure of the Luria Nebraska Neuropsychological Battery (LNNB) Form II was examined. A principle components factor analysis was performed on a sample of 102 psychiatric and neurologic subjects. It was necessary to remove 45 items from the analysis due to perfect performance by most subjects. The results were orthogonally rotated to simple structure using a Varimax method of rotation, and then compared to previous LNNB Form I and Form II results. Thirty-three factors were generated in the Exploratory Factor Analysis (EFA) . There was a very high agreement with the factors from Form I. Only one new factor was identified that didn't have a comparable Form I factor, and this factor appears to have neurological support. The similarity of the factor solutions between the two forms supports the continued use of factors derived from Form I for the interpretation of Form II, and supports the underlying structure presupposed by Lurian constructs. The present study also tested the significance of the hypothesized factor structures through confirmatory factor analysis (CFA). No hypothesis about the underlying factor structure based on previous exploratory studies was supported. The CFA did suggest that the best factor solution to the LNNB Form II is one …

Perceptions of the Sudanese Professional Working in Saudi Arabia on Migration and Economic Development of the Sudan (open access)

Perceptions of the Sudanese Professional Working in Saudi Arabia on Migration and Economic Development of the Sudan

The brain drain emerged as a phenomenon in the Sudan in the early 1970's when a change in the political system was followed by a change in the economic situation. The oil price increases created a dynamic process that led to attractive employment conditions in the petroleum producing countries such as Saudi Arabia and to depressed economic conditions in the developing countries like the Sudan. The purposes of the study are to (a) obtain information on the Sudanese professionals working in Saudi Arabia, (b) determine what major factors influence their migration, and (c) to develop policy recommendations on the flow of migration from the Sudan. The population of this study were Sudanese professionals living in Saudi Arabia. Data were generated through surveying a sample of 300 subjects selected randomly from the defined population. A survey questionnaire based on the research questions was developed for this study. Data from 263 respondents were analyzed. The findings of the study suggest that the majority of the Sudanese professionals working in Saudi Arabia are male, between 30 to 40 years of age. They have many years of experience and a high level of qualifications. The factors that led to their migration are: (a) high …

Educational Activities at the University of Jordan in Two Decades (1962-1982)

This study examined the educational activities at the University of Jordan, established in 1962, which is the oldest university in the country. The study traced the historical development of the university, which emphasizes highly-qualified graduates, and analyzed some of its educational practices. Research on this subject is limited. Jordanians have written little about their educational system, and there is little evidence of foreign scholars' interest in the subject. Some researchers argued that national pride was the main reason for establishing the university, since financial resources were not available to initiate and sustain serious research. The university started in the fall semester of 1962 with 167 students and one faculty, the Faculty of Arts. Two decades later, the university had ten faculties: Commerce and Administrative Sciences, Sciences, Medical Sciences (Medicine, Nursing, and Pharmacy), Agriculture, Education, Law, Engineering, Sharia, and Physical Education. The total number of staff continued to increase from 7 in 1962 to 627 by 1982. The size of the physical structure increased from one building to 40 buildings with approximately 18,000 square meters in 1982. As of 1982, more than 15,253 students had graduated from the university with bachelor's, master's, and diplomas-in-education degrees. In 1972, the University of Jordan …

A Comparison of Adult Children of Alcoholic Families with Adult Children From Non-Alcoholic Families on Depression, Self-Esteem, and Anxiety

The problem of this study was to test the differences between adult children from alcoholic families with adult children from non-alcoholic families on levels of depression, self-esteem, and anxiety. The sample consisted of 203 volunteers, all from the Counselor Education Department, 150 females and 53 males, ages 19 and older. Volunteers who were noted as being adult children of alcoholic families numbered 60. Measures used were the Children of Alcoholics Screening Test (CAST), the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), and the Coopersmith Adult Self-Esteem Inventory (SEI). Multivariate Analysis of Variance was used to test for differences between groups. In addition, a secondary analysis using a one-way MANOVA was used to test for differences between dysfunctional and functional family of origin status on the dependent variables of depression, self-esteem, and anxiety.

A Spectral Analysis of Selected Vowels Sung by Bass and Baritone Student Singers (open access)

A Spectral Analysis of Selected Vowels Sung by Bass and Baritone Student Singers

While a limited body of research pertaining to vocal sound quality exists, technological advances in sound analyses have facilitated a reexamination of vocal timbre. The sound quality of sung vowels ([ a], [e ], C i ]) produced by ten baritone/bass singers at the University of North Texas was analyzed by the use of Fourier analysis and electronic digital equipment. This procedure and equipment produced results over a wider frequency range with greater accuracy than prior studies on vocal timbre. The study sought to answer the following questions: (1) Using formant regions between 0-20 kHz for comparison, what similarities and differences can be observed among spectra produced from [a], [e], and [ i ] vowels sung by baritone/bass singers? (2) Using formant regions between 0-20 kHz for comparison, what similarities and differences can be observed among spectra produced from [a], [ e ], and [ i ] vowels sung by baritone/bass singers with regard to individual singers? (3) Approximately what vocal-tract tube lengths were used by baritone/bass singers when performing [a], [e ], and [ i ] vowels? (4) What similarities in vocal-tract tube lengths can be generalized as to [ a], L e ], and [ i ] vowels …

Anomalous Behavior in the Rotational Spectra of the v₈=2 and the v₈=3 Vibrations for the ¹³C and ¹⁵N Tagged Isotopes of the CH₃CN Molecule in the Frequency Range 17-95 GHz (open access)

Anomalous Behavior in the Rotational Spectra of the v₈=2 and the v₈=3 Vibrations for the ¹³C and ¹⁵N Tagged Isotopes of the CH₃CN Molecule in the Frequency Range 17-95 GHz

The rotational microwave spectra of the three isotopes (^13CH_3^12C^15N, ^12CH_3^13C^15N, and ^13CH_3^13C^15N) of the methyl cyanide molecule in the v_8=3, v_8=2, v_7=1 and v_4=1 vibrational energy levels for the rotational components 1£J£5 (for a range of frequency 17-95 GHz.) were experimentally and theoretically examined. Rotational components in each vibration were measured to determine the mutual interactions in each vibration between any of the vibrational levels investigated. The method of isotopic substitution was employed for internal tuning of each vibrational level by single and double substitution of ^13C in the two sites of the molecule. It was found that relative frequencies within each vibration with respect to another vibration were shifted in a systematic way. The results given in this work were interpreted on the basis of these energy shifts. Large departure between experimentally measured and theoretically predicted frequency for the quantum sets (J, K=±l, ϑ=±1), Kϑ-l in the v_8=3 vibrational states for the ^13c and ^15N tagged isotopes of CH_3CN showed anomalous behavior which was explained as being due to Fermi resonance. Accidently strong resonances (ASR) were introduced to account for some departures which were not explained by Fermi resonance.

A Study of the Influences Upon Pre-Service Teachers' Pre-Planning, Lesson Planning, and Bases for Interactive Decision Making During Lesson Implementation

The primary objective of this study was to describe the influences upon pre-service elementary teachers' preplanning, lesson planning, and bases for interactive decision making during their lesson implementation. Six female volunteer pre-service elementary teachers from the teacher preparation program at the University of North Texas planned and taught three separate lessons in one of the following content areas-social studies, language arts, mathematics, science, and safety, at six different schools in the north Texas area. Each element of the lesson plans (18 total) was classified for analysis. Following the presentation of each lesson, the pre-service teachers were asked to use the repertory-grid technique to sort out five decisions from a series of lesson-implementation decisions which had been observed and recorded by the investigator. Then the six pre-service teachers were interviewed by the investigator using the stimulated recall technique. During the interview, each decision was discussed with the pre-service teachers, who responded to seven structural questions that probed their concerns, attitude, type of concerns, and number of concerns. The six pre-service elementary teachers possessed some ability to direct students in their classroom learning using activities and instructional knowledge. This enabled them to notice individual student performance and that of students in the …

The Lyric, Elegiac, and Euphonic Qualities of Ernst Krenek's Compositional Style as Exemplified in the Early Toccata und Chaconne über en Chorale, "Ja, ich glaub an Jesum Christum," Op. 13: Together with Three Recitals of Selected Works of W.A. Mozart, F. Schubert, C. Nielsen, L.v. Beethoven, J. Brahms, F. Liszt, A. Berg and F. Martin

Ernst Krenek is noted and often criticized for the diversity of his overall output. However, one finds that his entire output is held together by a unique temperament regardless of stylistic changes. It is significant to compare the piano works to one another as the piano was the instrument he repeatedly turned to while testing new stylistic ideas. In writing about Krenek's music, Glenn Gould states eloquently and concisely that three qualities prevail in all of Krenek's mature output: the lyric, elegiac, and euphonic. These qualities are present in the early Toccata und Chaconne uber den Chorale, "Ja, ich glaub an Jesum Christum," Op. 13. It is lyrical in that melody is of utmost importance. One finds that melodic writing prevails in the other piano works as well regardless of when they were written. The elegiac also permeates the work. The Toccata and Chaconne shares with other later works this quality of seriousness, repose, and deep meaning. The Toccata and Chaconne is also euphonic. Krenek's overall style is one which does not shock or offend an audience. In a detailed comparison of the Toccata and Chaconne to later piano works, one may clearly see what Krenek specifically does musically to …

Individual Resources, Social Environment, and Flood Victimization (open access)

Individual Resources, Social Environment, and Flood Victimization

The study is a contextual analysis of flood victimization. Victimization is defined as the social, psychological, and physiological aftermath experienced by victims of a disaster. Disaster researchers concentrate on the victims' characteristics to explain the varying degrees of their victimization, providing only ambiguous results. Theorists such as Kreps, Wildavsky, and Douglas contend that the outcomes of disasters are contingent upon social structure. This analysis treats victimization as one such outcome. The condition and behavior of individuals can be explained by the presence of disaster and the conditions of social organization. A model explains victimization based on individual's attributes (individual resources), his social environment, and the disaster characteristics. This study uses the 1984 Mingo Creek Flood Victims Survey data to test the model. The data contain information measuring victimization. The survey data are linked with 1980 Census tract data. The tract data provide indicators of the social networks. This tract information, the contextual variables, taps the social conditions, including poverty, unemployment, geographic mobility, and family patterns. This study uses factor analysis to identify the dimensions of victimization. Regression tests the relationship between the contextual variables, the individual resource variables, the disaster characteristic variables, and victimization. The results of the analysis show …

"Beowulf": Myth as a Structural and Thematic Key (open access)

"Beowulf": Myth as a Structural and Thematic Key

Very little of the huge corpus of Beowulf criticism has been directed at discovering the function and meaning of myth in the poem. Scholars have noted many mythological elements, but there has never been a satisfactory explanation of the poet's use of this material. A close analysis of Beowulf reveals that myth does, in fact, inform its structure, plot, characters and even imagery. More significant than the poet's use of myth, however, is the way he interlaces the historical and Christian elements with the mythological story to reflect his understanding of the cyclic nature of human existence. The examination in Chapter II of the religious component in eighth-century Anglo-Saxon culture demonstrates that the traditional Germanic religion or mythology was still very much alive. Thus the Beowulf poet was certainly aware of pre-Christian beliefs. Furthermore, he seems to have perceived basic similarities between the old and new religions, and this understanding is reflected in the poem. Chapter III discusses the way in which the characterization of the monsters is enriched by their mythological connotations. Chapter IV demonstrates that the poet also imbued the hero Beowulf with mythological significance. The discussion in Chapter V of themes and type-scenes reveals the origins of …
