Trace Elemental Analysis of Ashes in the Combustion of the Binder Enhanced d-RDF by Inductively Coupled Plasma Atomic Emission Spectroscopy (open access)

Trace Elemental Analysis of Ashes in the Combustion of the Binder Enhanced d-RDF by Inductively Coupled Plasma Atomic Emission Spectroscopy

Incineration is an attractive solution to the problems of disposing of municipal solid wastes and supplying energy. Because up to 25 percent of the waste in refuse-derived-fuel systems is ash, the physical and chemical characteristics of ash become more and more important for its potential impacts and methods suitable for their disposal. Trace elements concentration in ash is of great interest because of its relationship to regulatory criteria under the Resource Conservation and Recovery Act (RCRA) regarding toxicity and hazards. The applications of a microwave oven sample dissolution method has been tested on a variety of standard reference materials, with reproducible and accurate results. Fourteen trace elements, As, Ba, Be, Cd, Cr, Cu, Hg, Ni, Pb, Sb, Se, Tl, V, and Zn, from the dissolved ash samples were determined by inductively coupled plasma atomic emission spectrometry.

Transposition and the Transposed Modes in Late-Baroque France (open access)

Transposition and the Transposed Modes in Late-Baroque France

The purpose of the study is the investigation of the topics of transposition and the transposed major and minor modes as discussed principally by selected French authors of the final twenty years of the seventeenth century and the first three decades of the eighteenth. The sources are relatively varied and include manuals for singers and instrumentalists, dictionaries, independent essays, and tracts which were published in scholarly journals; special emphasis is placed on the observation and attempted explanation of both irregular signatures and the signatures of the minor modes. The paper concerns the following areas: definitions and related concepts, methods for singers and Instrumentalists, and signatures for the tones which were identified by the authors. The topics are interdependent, for the signatures both effected transposition and indicated written-out transpositions. The late Baroque was characterized by much diversity with regard to definitions of the natural and transposed modes. At the close of the seventeenth century, two concurrent and yet diverse notions were in evidence: the most widespread associated "natural" with inclusion within the gamme; that is, the criterion for naturalness was total diatonic pitch content, as specified by the signature. When the scale was reduced from two columns to a single one, …

The Trombone Sonatas of Richard A. Monaco (open access)

The Trombone Sonatas of Richard A. Monaco

This lecture-recital investigated the music of Richard A. Monaco, especially the two sonatas for trombone (1958 and 1985). Monaco (1930-1987) was a composer, trombonist and conductor whose instrumental works are largely unpublished and relatively little known. In the lecture, a fairly extensive biographical chapter is followed by an examination of some of Monaco's early influences, particularly those in the music of Hunter Johnson and Robert Palmer, professors of Monaco's at Cornell University. Later style characteristics are discussed in a chapter which examines the Divertimento for Brass Quintet (1977), the Duo for Trumpet and Piano (1982), and the Second Sonata for Trombone and Piano (1985). The two sonatas for trombone are compared stylistically and for their position of importance in the composer's total output. The program included a performance of both sonatas in their entirety.

Twenty-Six Two- and Three-Voiced Canons by Johann Walter Transcribed for French Horn (open access)

Twenty-Six Two- and Three-Voiced Canons by Johann Walter Transcribed for French Horn

This thesis provides modern transcriptions for horn of twenty-six two- and three-voiced canons by Johann Walter, thereby adding to the literature available from the sixteenth century for that instrument. This project specifically attempts to introduce the high school and college student hornist to modal music in strict fugal form; the transcriptions appear as an appendix. The topics discussed in the body of this thesis include the canon, Johann Walter's life and significant contributions, sixteenth-century instrumental music, musicians' guilds, the zink, and the horn. This work is not intended to offer a comprehensive history of any of these areas, but to aid the teacher and student in the preparation and performance of these transcriptions.

Unity, Ecstasy, Communion: The Tragic Perspective of W.B. Yeats (open access)

Unity, Ecstasy, Communion: The Tragic Perspective of W.B. Yeats

As a young man of twenty-one in 1886, William Butler Yeats announced his ambition to unify Ireland through heroic poetry. But this prophetic urge lacked structure. Yeats had only some callow notions about needing self-possession and appropriate control of his imagery. As a result, his search for essential knowledge and experience soon led him into occult and symbolist vagueness. Yeats' mind grew flaccid, and his art languished in preciosity for over a decade. Lotos-eating had replaced prophetic fervor. However, early in the new century, as Yeats neared middle age and permanent mediocrity, he recovered his early zeal and finally found the means to give it artistic shape. Through daily theatre work he had discovered tragedy. And through personal trials he had developed a tragic sense. Hence, an entire tragic perspective was born, one that would dominate Yeats' mind and art the rest of his life. Locating the contours of Yeats' shift in-viewpoint, then, provides the key to understanding the man and his mature work. The present study does just that, tracing the origin, development, and elaboration of Yeats' tragic perspective, from its theoretical underpinnings to its poetic triumphs. Above all, this study supplies the basic context of Yeats* careers why …

The Use of the Tenorhorn and Baryton in the Brass Chamber Music of Oskar Böhme and Victor Ewald: a Lecture Recital, Together with Three Recitals of Selected Works of J. Boda, J. Brahms, G. Jacobs, G. Mahler, T.R. George, J. Castérède, A. Capuzzi and Others (open access)

The Use of the Tenorhorn and Baryton in the Brass Chamber Music of Oskar Böhme and Victor Ewald: a Lecture Recital, Together with Three Recitals of Selected Works of J. Boda, J. Brahms, G. Jacobs, G. Mahler, T.R. George, J. Castérède, A. Capuzzi and Others

The tenorhorn and baryton (euphonium), as members of the valved conical brass family, were highly regarded by Oskar Böhme (1870-1938) and Victor Ewald (1860-1935). This study examines the role the tenorhorn and baryton played in selected works by these two composers of the Russian Chamber Brass School. A chronology of the research leading to the discovery and naming of the Russian Chamber Brass School is included as well as a discussion on brass chamber music performance practice both then and now.

Validating the Rorschach Defense Scale by Examining Defensive Functioning in College Students (open access)

Validating the Rorschach Defense Scale by Examining Defensive Functioning in College Students

This study attempted to provide validation for Lerner and Lerner's Rorschach Defense Scale by investigating the relationship between primitive defenses as measured by the Rorschach Defense Scale, level of object relations as measured by the Developmental Analysis of the Concept of the Object Scale, and characteristic defensive operations as assessed by the Minnesota Multiphasic Personality Inventory. One hundred and twenty undergraduates completed the Rorschach and MMPI, and the RDS and DACOS were applied to their Rorschach responses. The results show a significant positive correlation between use of primitive defenses and level of object relations development -and a significant negative correlation between the defense Projective Identification and MMPI scale 6 (Paranoia) elevation. Overall, these results did not support the validity of the RDS.

Validity of a Brief Self-Rating Visual Analogue Pain Questionnaire (open access)

Validity of a Brief Self-Rating Visual Analogue Pain Questionnaire

It is believed by many researchers that little attention has been given to patients' perceptions of the impact of chronic pain on their lives. In recognition of this need, G. Frank Lawlis, C. Edward McCoy, and David K. Selby developed the Dallas Pain Questionnaire (DPQ) to assess the amount of chronic pain that affects four aspects (daily activities, work-leisure activities, anxiety-depression, and social interest) of the patients' lives. The present study, conducted to validate the DPQ's statistical properties, first reviews the literature addressing the various theories and varieties of pain, its opiates, and the two current approaches to quantify pain. This study included a total of 143 subjects. Clinical subjects were 104 inpatients in the Spinal and Chronic Pain Center at Medical Arts Hospital and 15 chronic pain outpatients released to work. Normal subjects consisted of staffing personnel (n = 13) and flight assistance employees (U = 11)- Both clinical and normal groups completed the DPQ. The Minnesota Multiphasic Personality Inventory (MMPI) was administered only to the clinical population. Results suggest that the DPQ is both externally reliable (stability reliability coefficient of .970) as well as an internally consistent instrument. Two factors emerged from factor structure analysis. Factor one (63.2% …

Validity of the California Psychological Inventory for Police Selection (open access)

Validity of the California Psychological Inventory for Police Selection

The study examined the validity of using the California Psychological Inventory (CPI) as a tool for police selection. The mean CPI profile of 211 police applicants was first compared to that of the CPI norms. Five performance criterion measures--retention on the job, academy grades, supervisory ratings, commendations, and reprimands of police officers--were studied to investigate their relationships with the CPI scales. The results indicated that there were significant mean differences on all the CPI scales between police applicants and CPI norms. The scale of Flexibility significantly differentiated the criterion groups of retention on the job. The CPI was useful in predicting academy performance; however, it did not correlate well with job performance as measured by supervisory ratings, commendations, and reprimands.

The Validity of the MMPI in the Selection of Police Officers (open access)

The Validity of the MMPI in the Selection of Police Officers

This study examined the validity of the Minnesota Multiphasic Personality Inventory (MMPI) as a predictor for police officer selection. The MMPI profiles of 212 police officer applicants selected to enter the training academy were compared to the standardized MMPI norms. Significant differences between the police officers and the normative population were found on all but two scales. When the average profile of officers still on the police force was compared with the average profile of terminated officers, two scales were significantly different. Significant correlations were obtained between four MMPI scales and the academy score criterion and two scales each for the commendation and supervisory rating criteria. A prediction equation was developed for academy score using multiple regression analysis.

Variables Affecting Grandchildren's Perceptions of Grandparents (open access)

Variables Affecting Grandchildren's Perceptions of Grandparents

While many studies have investigated grandparenthood from the point of view of the grandparent, few have considered this issue from the perspective of the grandchild. In this respect, a number of variables (i.e., grandchild age and gender, parents' marital status, and grandparents' age, gender, education, kinship position, residential proximity to and frequency of visiting with grandchildren, perceived influence on the grandchild, style of grandparenting, and relationship with the parents) were investigated as determinants of the quality of the grandparent-grandchild relationship in a sample of 171 adolescents and young adults. It was found that different sets of variables operated for different grandparents to predict the quality of their relationships with grandchildren.

Variations on a Theme: The Monomyth in John Fowles's The French Lieutenant's Woman (open access)

Variations on a Theme: The Monomyth in John Fowles's The French Lieutenant's Woman

This study analyzes the development of the major characters in Fowles's novel - Charles, Sarah, and Sam - in terms of the heroic quest motif. Using the basic pattern of the heroic quest, the monomyth, that Joseph Campbell sets forth in his The Hero with a Thousand Faces, I attempt to show that Fowles's novel may best be understood as the story of three separate heroic quests whose paths cross rather than as the story of a single hero or heroine. This reading seems to account best for all elements of the novel and to explain best the final positions of the characters in question as well as providing a rich appreciation of the novel's wealth of imagery.

Visual Aspects of Internal Correspondence and Their Impact on Communication Effectiveness (open access)

Visual Aspects of Internal Correspondence and Their Impact on Communication Effectiveness

Technologists predict that electronic information dissemination will create a paperless work environment. In spite of such predictions, paper-based internal communication will remain the primary medium for disseminating information in organizations for decades to come. However, electronic technology will have an impact on paper information production that may be more profound than changes following word processing's introduction. Previously unavailable for everyday production to enhance word meaning, certain graphic techniques now can be used to access readers' preconditioned symbol meanings to increase comprehension of routine correspondence and information internalization. This quasi-experimental field study examines interactions among laser-printer graphic treatment and communication variables as contributors to explaining variance in comprehension. Set Multiple Regression/Correlation analysis identifies significant variance explained by conditional relationships between near-typeset quality text and readers' self-interest and between near-typeset quality text and text's readability. The conditional relationship of near-typeset quality and self-interest shows increase in reader comprehension at a greater rate than the comprehension increase rate attributed to the reader's self-interest increase alone. This suggests that conditional relationships may be accessing an internal judgment process interpreting greater self-interest in near-typeset printed text. The conditional relationship between near-typeset quality and readability reveals that at more difficult reading levels comprehension is greater for …

The West Indies College and its Educational Activities in Jamaica, 1961-1987 (open access)

The West Indies College and its Educational Activities in Jamaica, 1961-1987

The West Indies College is an institution of higher education in Jamaica which was established by the Seventh-Day Adventist Church in 1909. It has had three names: 1909-1923, West Indian Training School; 1924-1958, West Indian Training College, and 1959-present, West Indies College. The school has been served by over 20 presidents. The needs of the Seventh-Day Adventist Church, the Mandeville community, Jamaica, and the West Indies region continue to play an important role in the addition and elimination of academic programs at the college. Present programs have attracted students from Africa, North and South America, the West Indies, and Europe. The college has industries that are used as facilities to provide the work-study program for students to fulfill the college's operational philosophy of educating the entire person. The industries assist students in the development of manual skills and in the payment of tuition. The West Indies College is funded by grants of the Seventh-Day Adventist Church, tuition fees, profits from industries, and individual contributions. The school also receives a financial advantage in the form of tax exemption from the Jamaican government. An organized Department of Alumni Affairs assists the college in moral, professional, and material support. Due to the generosity …

Wild Nights! Wild Nights! The Dickinsons and the Todds: A Screenplay (open access)

Wild Nights! Wild Nights! The Dickinsons and the Todds: A Screenplay

Emily Dickinson's seclusion is explored in light of her family's strange entanglement with the Todds. Austin Dickinson's affair with Mabel Loomis Todd, and the effect on the lives of Susan Dickinson, Lavinia Dickinson, Martha Dickinson Bianchi, David Todd, and Millicent Todd Bingham, provide a steamy context for the posthumous publication of Emily Dickinson's poetry. The screenplay includes original music (inspired by the dashes and an old hymn) for two poems: "Wild Nightsl Wild Nights!" and "Better - than Music!" Also included are visualizations of many of Dickinson's images, including "circumference," "Eden," "the bee," and "immortality."

The Word and Tragedy the Revelation of Divine Mystery in the Portrayal of Man as Language (open access)

The Word and Tragedy the Revelation of Divine Mystery in the Portrayal of Man as Language

This study suggests that tragedy sees human action as synonymous with language and that it uses a method similar to that of a hermeneutic phenomenology to portray man as experiencing spirituality in a confrontation with expression. This confrontation takes the form of a pattern that leads to a revelation that all human action springs from the spirit. Word as action is thus placed into a spiritual context, containing in itself the key to the divine significance of the human experience. As a cultural manifestation, this pattern exists not only in literary tragedy, but also in the Hebrew Scriptures as narratives and poetry. This study examines this tragic pattern in Genesis, the Book of Job, Oedipus, and King Lear.
