This paper discusses the works of its author and includes images of the works. Douglas Parker Darracott discusses the process of creating an American portrait in 1992 and performs research on related literature and American society during this period.

The act of putting anything on a base isolates it and makes it seem more precious. The base separates the viewer from the sculpture and affects the relationship between the sculpture and viewer. The problem for me was to remove the base and experiment with the possibilities now opened to my work. The purpose of this study was to explore the presentation potentials of sculpture freed from the constraints of the plinth.

The objective of my problem in lieu of thesis was to produce twenty hand-built porcelain objects which reflected this conception of beauty. To review the success of my project, I asked three questions to evaluate my work. 1. Was there significant structure to my works? 2. Was there significant discord within these structures? 3. Did the tension created through the interaction of these two elements of my work create beauty?

This problem tries to bring together a comprehensive array of themes. There has been a duality between painterly techniques, recognizable images and disjunctive imagery. The subtractive painting technique used has created smooth transitions between images and made these hybrid realities more convincing.

It was impossible to document all of the important dancers of the era; however, certain individuals were notably exceptional. The purpose of this study was to document and illustrate some of those dancers who impacted and influenced the development of American vernacular dance during the early twentieth century through the mid-1940's. The individuals chosen were as follows: Dewey "Pigmeat" Markham, John Bubbles, Bill Robinson, Earl "Snakeships" Tucker, James Walker and Charles Green (Chuck and Chuckles), Katherine Dunham, Honi Coles and Cholly Akins (Coles and Akins) Josephine Baker, The Derry Brothers (Ananias, Jimmy and Warren), Eddie Rector, Willa Mae Ricker and Leon James. Emphasis was concentrated on capturing an accurate likeness of the individuals as well as on establishing a specific mood. Since all of the above-mentioned individuals were dancers, a special effort was made to recreate the lighting and aura of the stage.

Although drawing had offered me many avenues for image exploration and mark making, it lacked the actual physical relief surface that was a natural part of the printmaking plate process (i.e., intaglio plates or relief surfaces). Sculpture allowed the images and marks to be realized dimensionally in the round; therefore, the images became objects.

Prior to 1990 I worked exclusively with large scale formats, using traditional oil painting media on canvas. During that year I became interested in the effect produced by more intimate passages within larger works. Discovery of a scroll of Chinese ink drawings in 1992 increased my interest in small scale composition.

This study examines whether water conservation is actually being incorporated into municipal water management practices. The development of a conservation policy from a general goal declaration to specific programmatic practices is reviewed for a Texas state water agency, the Texas Water Development Board. From January 1986 through September 1989, 102 political units in Texas applied to the Board for water-related loan funds and thus were required to implement municipal water conservation plans. Two aspects of this conversation policy are assessed: one, the Board's procedural arrangements for the development and review of water conservation plans, and two, the conservation plans of each political unit. It is concluded that Texas state water managers, and local manager also, have yet to incorporate conservation as a significant planning tool for the achievement of water management goals.

The effect of pH upon the aquatic toxicity of cyfluthrin was determined in 48 h static acute toxicity tests using 2nd instar Chironomus tentans larvae. Tests were conducted in both dechlorinated tap water and lake water of pH 8.0, 7.2, and 6.6. After 48 h, immobilized and dead larvae were removed and replaced with 2nd instar larvae to assess the persistence of toxicity. Midges were cultured in water adjusted to the pH values used in testing. Toxicity if cyfluthrin varied inversely with pH. An increase in the pH of tap water by 2 units resulted in a 2-decrease in toxicity. Toxicity of cyfluthrin also varied between tap and lake water of the same pH. EC50 values in lake water were approximately 2-3 times lower than those in tap water. Toxicity in the lake water and tap water at every pH tested was also significantly different when regression line elevations were compared. Natural waters amended with cyfluthrin were consistently more toxi to the chironomids than tap water of the same pH. Persistence of cyfluthrin at low pH also influenced chironomid behavior. Recovery of normal behavior generally began within 24 h at pH 8.0 At pH 6.0, recovery did not begin until …

The rate constant for the reactions of oxygen atoms with nitric oxide and silane were determined using a discharge flow apparatus. A microwave discharge through O2N2 and Ar was used to produce oxygen atoms. The rate constant for the reaction O + NO + Ar was determined to be (7.0+0.4) x 10^32 cm^6 s^-1 and is in good agreement with previous measurements. Modeling of the O +SiH₄ reaction was performed to determine the correction to the rate constant due to secondary reactions. The rate constant for the reaction O + SiH₄ was determined to be (3.3 +/- 0.3) x 10⁻¹³ cm³ s⁻¹ and is in good agreement with previous measurements. Previous literature, thermochemistry, and spin conservation were used to determine a probable mechanism for the O + SiH₄ reaction.

The thesis examines the reasons why the German National Assembly of 1919 chose proportional representation to elect officials to the German Reichstag. Sources include the series Quellen zur Geschichte des Parlamentarismus and die politische Parteien, the "Hajo Holborn Papers", and the Reich Ministry of Interior debates concerning the institutional draft. The thesis traces the arguments for proportional representation, its use throughout Europe before 1914, and voting reform in Germany during World War I. The thesis surveys the German provisional government's adoption of proportional representation, emphasizing the constitutional drafts of Hugo Preuss and the role of the provisional government. Finally, the thesis scrutinizes the National Assembly debates, concluding that most of its members had already decided to follow the provisional government's course and accept proportional representation.

This thesis focuses upon the impact of war upon the progressive movement in Texas during 1914-1918. Chapter I defines progressivism in Texas and presents an overview of the political situation in the state as relating to the period. Chapter II discusses the negative impact that the first two years of World War I had upon the reform movement. Chapter III examines the revival of the Anti-Saloon League and the 1916 Democratic state convention. Chapter IV covers the war between James E. Ferguson and the University of Texas. Chapter V tells how the European war became a catalyst for the reform movement in Texas following America's entry, and its subsequent influence upon the election of 1918. Chapter VI concludes that James E. Ferguson's war with the University of Texas as well as World War I were responsible for the prohibitionist victory in the election of 1918.

This study identified and defined leader behaviors with two levels of leadership in a self-managed team organization. Job analysis methodology was used. A comparison of task importance values was made within groups and between hierarchical levels in the organization. Identified leader behaviors were compared with effective, traditional leader performance. Qualitative data collected throughout the investigation clarified an integrative model for effective organizations developed from the literature. The model included leader characteristics and team member behaviors when using self-managed teams.

Adolescent fertility is a problem that is urgent in developing countries due to rapid population growth rates. To gain a better understanding of adolescent fertility within developing countries a study was undertaken to examine adolescent sexual behavior among teens within a developing country, Zambia. A self-administered questionnaire was given to secondary school going teenage women in Zambia. The sample population consisted of 503 women between the ages of 12 and 19. The survey was analyzed using both regression and univariate analysis of the data. The findings revealed that a high percentage of the teens have initiated sexual activity; yet few (4.2%) have ever used modern contraceptive methods. Suggestions were made for family planning programs that would involve both parents and their children.

This thesis presents a simple method for the concurrent manipulation of linearly ordered data structures on hypercubes. The method is based on the existence of a pruned binomial search tree rooted at any arbitrary node of the binary hypercube. The tree spans any arbitrary sequence of n consecutive nodes containing the root, using a fan-out of at most [log₂ 𝑛] and a depth of [log₂ 𝑛] +1. Search trees spanning non-overlapping processor lists are formed using only local information, and can be used concurrently without contention problems. Thus, they can be used for performing broadcast and merge operations simultaneously on sets with non-uniform sizes. Extensions to generalized and faulty hypercubes and applications to image processing algorithms and for m-way search are discussed.

This paper is the result of a study of the power method to find dominant eigenvalues of square matrices. It introduces ideas basic to the study and shows the development of the power method for the most well-behaved matrices possible, and it explores exactly which other types of matrices yield to the power method. The paper also discusses a type of matrix typically considered impossible for the power method, along with a modification of the power method which works for this type of matrix. It gives an overview of common extensions of the power method. The appendices contain BASIC versions of the power method and its modification.

This thesis is focused on informal sector establishments in Kenya and how they contributes to employment creation, income generation and economic development. The research examines how the informal sector has developed between the years 1986-1989. The study indicates that the informal sector can absorb those people who are unemployed and cannot find jobs in the formal sector. The first chapter describes the definition and interpretation of the informal sector. The discussion of the related .literature, development of the informal sector, politics of the urban informal sector and controversies are described in chapter II. Chapter III describes the regional and sectoral analysis in employment generation. Chapter IV focuses on projections and promotion policies. Concluding remarks and the importance of the informal sector are represented in chapter V.

The purpose was to measure any statistically significant differences in pitch-matching skills among three classes of third grade students when using either adult male voice, piano, or resonator bells as melodic models for rote instruction of classroom singing. Each class was randomly assigned one of the three melodic models for a ten week treatment phase. Results indicated no significant differences in pitch matching skills between any of the three groups. No significant differences in pitch matching skills were found according to gender of subjects or among class piano students and non-piano students. Findings indicated overall improvement in pitch matching skills of subjects from pre-test to post-test phase.

Individuals responding in a socially desirable (SD) fashion, rather than in a manner that reflects their true behavior, has been a problem for self-report questionnaires since their inception. The purpose of this study was to examine the hypothesis that the probability an item is endorsed on a self-report measure of anger is directly proportional to the rated SD of that item. Eighty-two subjects completed the Buss-Durkee Hostility Inventory (BDHI), the Profile of Moods State (POMS), and the State- Trait Anger Expression Inventory (STAXI). A probability of endorsement was computed for each of the measures' items. Twenty additional subjects rated the measures' items for SD. Each item's SD rating was paired with the probability the item was endorsed to produce a correlation coefficient for each measure. Results strongly support the stated hypothesis. Directions for future research are discussed.

Ceriodaphnia dubia is widely used as a test organism in monitoring water quality. At the present time, cultures must be continuously maintained in the laboratory. In an attempt to avoid continuous culture and maintenance, the hatching of ephippial eggs of C. dubia would provide test organisms when needed. In order to determine the parameters required for maximum hatching, approximately ninety-four thousand ephippia were exposed to a variety of conditions ranging from light and temperature regimes to drying and freezing. A low hatching yield occurred which is believed to be caused by diminished ephippia viability and/or fertility. To evaluate factors influencing the viability and fertility rate, stains of embryos were examined as were male to female ratios and mating experiments.

Turkey is considering privatizing its telecommunications system. Any developing country must analyze whether its economic, social, and institutional environment is appropriate for the privatization of a utility. The purposes of this study are (1) to establish a model to assist policy makers, (2) to analyze whether Turkey meets the prerequisites for telecommunications privatization, and (3) to provide Turkish leaders pragmatic policy alternatives pertaining to privatization of the Turkish Telecommunications system.High inflation rate, weakness of the private sector and the lack of regulatory regime are the major impediments facing Turkey's privatization efforts. Turkey might consider several options including (1) not privatizing at all, (2) retaining public ownership of the network operations while privatizing only the physical equipment market, or (3) following the British privatization model.

The Reflection is a piece of chamber music that describes the human nature through the use of different "meanings" in music. By using various leitmotifs and different compositional techniques, the music becomes a helpful tool to reflect meanings. On the other hand, this piece uses one special idea, which is that the whole piece can be explained in terms of visual arts. Each primary motive represents a "primary color" that reflects various "moods" or "emotions." Through using combinations and mixtures of color, different "sceneries" are formed. Furthermore, The Reflection has three basic aspects: the function of transmitting messages through music; the exploration of different functions of fifth; and the emphasis of meaning, sound effect and timbre.

This thesis examines French architect Eugene-Emmanuel Viollet-le-Duc (1814-1879), who combined eighteenth-century Rationalism with the historicist, anti-academic message of Romanticism, which was impelling the nineteenth-century architectural reform movement into the industrial age. Sources used include Viollet-le-Duc's architectural drawings and published works, particularly volume one of his Entretiens sur l'Architecture. The study is arranged chronologically, and it discusses his career, his restoration work, and his demands for reform of architectural education. One chapter contains a detailed analysis of his Entretiens. This thesis concludes that Viollet-le-Duc was as much a historian as he was an architect, and it notes that his hopes for reform were realized in the twentieth century.

The effects of the inhibitory neurotransmitters gammaamino butyric acid (GABA) and glycine were characterized on spontaneous activity recorded from mouse spinal cord cultures. The GABA concentration which completely inhibited burst activity was chosen as a quantifiable measure of culture drug response and was used to 1) assess interculture and intraculture variability, 2) determine the influence of culture age and initial activity on GABA responses, and 3) compare the GABA responses between networks obtained from whole spinal cord and ventral half spinal cord. Results showed that 1) no significant variability existed either within or among cultures, 2) the initial culture activity directly affected GABA responses, 3) the culture age had no effect on GABA responses, and 4) there was no significant difference in GABA responses between the two spinal cord tissues.
