Convergence of Infinite Series (open access)

Convergence of Infinite Series

The purpose of this paper is to examine certain questions concerning infinite series. The first chapter introduces several basic definitions and theorems from calculus. In particular, this chapter contains the proofs for various convergence tests for series of real numbers. The second chapter deals primarily with the equivalence of absolute convergence, unconditional convergence, bounded multiplier convergence, and c0 multiplier convergence for series of real numbers. Also included in this chapter is a proof that an unconditionally convergent series may be rearranged so that it converges to any real number desired. The third chapter contains a proof of the Silverman-Toeplitz Theorem together with several applications.

Texas Outlaw Radio: the Prelude to United States v. Gregg et al. (1934) (open access)

Texas Outlaw Radio: the Prelude to United States v. Gregg et al. (1934)

Unlicensed radio stations in 1933 tested the Radio Act of 1927 as to whether or not the Federal Radio Commission (FRC) had the right to regulate radio stations whose signals were allegedly intrastate. The FRC believed it could regulate such radio stations and proceeded to confiscate equipment, charge individuals with violation of the law, and bring them to trial, either in an injunction hearing, a criminal trial, or both. The most formidable case was that of United States v. Gregg et al. The challenge was met by the FRC and the judge, whose decision is still quoted in legal documents. The decision upheld the Radio Act of 1927 and the FRC's right to regulate all radio stations, licensed or unlicensed.

Songs of Praise (open access)

Songs of Praise

Songs of Praise is a setting of four passages from the Psalms for soprano and chamber orchestra. The text is taken from Psalms 96, 114, 55, and 116 of the New American Standard Version, with each psalm scored as a separate movement. The duration of the work is approximately seventeen and one-half minutes. The instrumentation includes soprano, oboe, strings, and a percussion section of four players incorporating fourteen different instruments. The musical language employed is largely tonal, consisting generally of shifting tonal emphases achieved by exploiting the pitch relationships of traditional tonality. The movements are contrasting in character, according to the text, but generally of the same style. The vocal line predominates throughout spanning two octaves and a minor third from an A below middle C to a high C above the treble clef.

Types of Love in Selected Plays by Lillian Hellman (open access)

Types of Love in Selected Plays by Lillian Hellman

This study analyzed The Children's Hour, The Little Foxes, Watch on the Rhine, Toys in the Attic in terms of the forms of human love delineated by Erich Fromm in The Art of Loving. The motives and actions of one or more principal characters and their dramatic situations were studied. It was discovered that, in the plays that were examined, each character responded to his or her situation in a loving or a hateful manner and that these choices with regard to love provided the dramatic matrix of the play.

Foreign Direct Investment and Political Risk (open access)

Foreign Direct Investment and Political Risk

This paper will show that, despite the need for extension of foreign direct investment in the form of multinational corporations to capital-scarce, less developed countries, political risk creates a gap between the demand and supply of foreign investments. In Chapter II, the patterns of foreign direct investment are analyzed. Chapter III reviews the various sources of political risk and concludes that the existence of political risk is an obstacle to the formation of optimum level investment. Chapter IV discusses the relative positions of the less developed countries and the multinational corporations. Chapter V shows the problems caused by the absence of a universal, regulatory institution. Chapter VI presents case studies of corporations based in Chile, Peru, and Angola. Chapter VII suggests ways that political risk can be minimized.

The Effect of Human Alpha Interferon on Rat Kidney Cell Infected with Temperature-Sensitive Mutant of Rous Sarcoma Virus (open access)

The Effect of Human Alpha Interferon on Rat Kidney Cell Infected with Temperature-Sensitive Mutant of Rous Sarcoma Virus

LA31-NRK and B77-NRK are established cell lines that were normal rat kidney cells transformed with temperature-sensitive mutant (LA31) and wild-type Bratislava 77 (B77) of Rous sarcoma virus. It is recognized that many transformation-induced changes differentiate between normal and transformed cells. Morphology and four parameters of transformed cells such as saturation density, anchorage independence, plasminogen activator, and colony stimulating factor were used as indicators to observe the effect of human alpha interferon on the growth of NRK, LA31-NRK and B77-NRK. The results show that interferon could neither reverse the transformed cells to normal fashion nor change their behaviors or cause release of protease.

Clavichord Traits in Selected Late Eighteenth-Century Keyboard Pieces (open access)

Clavichord Traits in Selected Late Eighteenth-Century Keyboard Pieces

Several late eighteenth-century keyboard composers indicated that some of their works were written specifically for the clavichord, as opposed to the harpsichord or pianoforte. This demand was indicated by a composer's commentary, remarks made by a contemporary, or by Bebung and Tragen der Tone indications in the music. The thesis examines selected works of C.P.E. Bach, Johann Eckard, Nathanael Gruner, Johann Hassler, Christian Neefe, F.S. Sander, and Daniel Tt*rk, and discusses elements of the music that seem particularly suited to clavichord performance. These elements are Bebung, Tragen der TOne, finely nuanced dynamic indications, certain types of melodic writing, and a thin textural composition.

Properties of Normal Rat Kidney Cells Transformed by a Temperature-Sensitive Mutant (LA31) of Rous Sarcoma Virus (open access)

Properties of Normal Rat Kidney Cells Transformed by a Temperature-Sensitive Mutant (LA31) of Rous Sarcoma Virus

The basis of this investigation is to characterize growth property differences in normal versus virally transformed cells. Using a temperature-sensitive mutant of Rous sarcoma virus, the cells' transformation state is regulated by the growth temperature; at 33°C the cells are transformed, while at 39°C the cells have normal characteristics. The morphology of NRK cells is elongated and fibroblastic; when transformed the cells are rounded. Normal cells grow to a monolayer and stop, while transformed cells grow to saturation densities greater than just a monolayer amount. Transformed cells can form foci when grown in mixture with normal cells. Normal cells must be in contact with the culture vessel in order to grow, but transformed cells lack anchorage dependence for growth.

An Analysis of the Overt Teaching of the Monitor to Students of English as a Second Language (open access)

An Analysis of the Overt Teaching of the Monitor to Students of English as a Second Language

The overt teaching of the Monitor, or conscious rule awareness, to native Spanish-speaking ESL students was examined to note possible benefits to the students' oral English production. Native Spanish-speaking students of English (the experimental group) were taught an awareness of their ability to self-correct their spoken English. They were then compared to another group of native Spanish-speaking ESL students (the control group) in four areas: Ilyin Oral Interview score, total words produced, errors produced, and interference errors produced. The results of the study lend support to the theory that overt Monitor teaching could be beneficial to native Spanish-speaking students of English. The experimental group showed a significant gain in Ilyin scores and a significant reduction in the number of errors produced.

An Analysis of the Development, Function and Implication of Selected Myths Toward the Aged in American Society

The development, content, societal and individual effects of selected myths toward the aged in American society were reviewed and analyzed. Emphasis was placed on factors associated with the development of the myths . The myths were compared with facts or reality relative to the major dimensions of the lives of the aged. The functions and dysfunctions of the myths for the aged as a group, for the individual, and for society were analyzed. Secondary sources of data were utilized in the preliminary identification of the selected myths. The sources were also used to justify the selection and analyze the development of myths within their socio-cultural milieus. Myths were utilized in the analysis of the attitudes toward the aged, and the effects.

Initial Starting Posture and Total Body Movement-Reaction Time for Lateral Movement

Eighteen subjects each performed fifty-five trials which consisted of assuming an initial stance and then in response to a visual stimulus running to either the left or right. For each trial both the foot width spacing and orientation of the feet were varied. Direct and indirect measurements were taken of selected temporal and kinematic parameters. The conclusions were that no interactions or differences exist among foot width spacing, foot orientation, and direction of movement; the jab step start is the preferred initial movement; the preferred foot width spacing is 46.6 centimeters; the preferred angular orientation of both feet is approximately 1.36 radians.

Appearance or Function: Factors Related to the Likeability of Handicapped Individuals

Descriptions of obesity, cerebral palsy, and scoliosis were rank-ordered (from one to twenty) and rated on a five-point scale by 75 college students. The descriptions were of two types: with the appearance of an individual on five levels of severity of a disorder and with the appearance and level of functioning of an individual on five levels of severity of a disorder. The ranking data indicated males rank-ordered descriptions of obese individuals different from cerebral palsy (p < 0.01) and scoliosis (p < 0.05) . The ratings of the descriptions were analyzed in two studies with 2 x 2 x 2 x 5 ANOVA's. Three-way interactions of the level of severity, complexity of description, and type of disorder rated were discussed in terms of likeability of handicapped individuals .

Plasma Ion Concentrations in Selected Fishes from Four North Central Texas Reservoirs with Different Salinities (open access)

Plasma Ion Concentrations in Selected Fishes from Four North Central Texas Reservoirs with Different Salinities

Mean salinity concentrations in the four reservoirs (Moss, Ray Hubbard, Texoma and Possum Kingdom) ranged from 0.2 ppt in Moss Lake to 2.01 ppt in Possum Kingdom Lake. Reservoir sodium and chloride concentrations were hypotonic to hypertonic to plasma levels in all species. Interspecific differences were seen in ionic concentrations within each reservoir. Total osmotic and sodium concentrations in carp, Cyprinus carpio, were correlated to their concentrations in the reservoirs. No such relationship was noted for chloride, potassium and calcium. A laboratory study indicated that fish collection by electroshock did not bias plasma ion concentrations. Exposures to wide variations in ionic concentrations did not appear to induce stress in the species studied.

The Effects of Surface Type on Experienced Foot Contact Pressures and Lower Limb Functioning During Running Performance

The purpose of this study was to examine the effects of different surfaces on lower limb motion and encountered pressures at two locations on the plantar surface of the right foot. Nine females performed five trials for each of four surface conditions. The results provided no evidence for surface-related changes in experienced foot contact pressures. Both asphalt and grass surfaces resulted in the shortest relative time of forefoot immobility. No surface related differences were found for the range of pronation.

Effects of Managerial Experience on Assertiveness, Anxiety, and Locus of Control

The purpose of this study was to examine the effects of managerial experience on the relationships between assertiveness, trait anxiety, and internality, and on each of these constructs individually. Hypotheses were as follows: a) managers would be more assertive, internal, and less trait anxious than business students; b) males would be more assertive than females when students, not managers; and c) assertiveness and internality would relate positively to each other and negatively to trait anxiety. Subjects consisted of 30 managers and 53 business students. The first and third hypotheses were confirmed, although the assertiveness differences were not significant. Reasons for the observed outcome are discussed as well as implications for these constructs' ability to predict management potential.

Mast Cells in the Brains of Mice of Different Genotypes: A Histological Study (open access)

Mast Cells in the Brains of Mice of Different Genotypes: A Histological Study

Histamine is present in the central nervous system and is believed to be derived from neurons (50 percent) and mast cells (50 percent). This experiment was designed to analyze histologically the numbers and distribution of brain-associated mast cells in normal (+/+), mast cell deficient (W/W^v) and heterozygote (W/+, W^v/+) mice of the WBB6F_1 /J strain. Significant variations in the number and distribution of mast cells between the various genotypes were found. Based on the results, a hypothesis is proposed to account for the observed genotypical differences in mast cell numbers and distribution. Based on the total number of mast cells and the content of histamine in a typical mast cell, it is apparent that the mast cell is not a major source of brain histamine, suggesting that another non-neuronal pool of histamine must be present in the brain.

Mechanistic Assumptions and the East-West Conflict: a Critique (open access)

Mechanistic Assumptions and the East-West Conflict: a Critique

This paper addresses the influence of a mechanistic world view of East-West relations. The "classic" model of mechanism orders reality into a relationship akin to a simple clock or pump. In the model, discrete and unmodifiable parts, with no natural functional relationship to each other, are balanced and engineered into functional unity. This study shows how "environmental" conditions at the international level (ambiguity, complexity, and prolonged conflict) limit the ability of policy makers to define objective limits to containment, influencing them instead to follow the universal application of the "logic" of mechanism--that any imbalance must be checked by the container.

An Examination and Evaluation of the Role of Public Relations in Neiman-Marcus Fortnights

This study examines the organization, function, and role of public relations in Neiman-Marcus Fortnights. Fortnight is an annual October extravaganza combining cultural and community education with merchandising. Information was gathered by interviews with three people associated with Fortnight public relations. The public relations department follows general goals in planning Fortnight public relations activities. Audiences are not restricted. Public relations responsibilities are publicity, press relations, guest relations, community relations, and special events. Evaluations are made with respect to public relations activities of the previous Fortnight. Though public relations is of secondary importance to merchandising, the effectiveness of Fortnight activities would be improved with established objectives, specific audiences, and a formal means of evaluation.

Comparative Feeding Ecology of Leaf Pack-Inhabiting Systellognathan Stoneflies (Plecoptera) in the Upper Little Missouri River, Arkansas (open access)

Comparative Feeding Ecology of Leaf Pack-Inhabiting Systellognathan Stoneflies (Plecoptera) in the Upper Little Missouri River, Arkansas

The feeding ecologies of leaf pack-associated systellognathan stoneflies were examined from 6 June 1980 21 May 1981. Species composition, seasonal abundance, nymphal growth, feeding habits and mouthpart morphology were determined for the eight dominant stonefly species. Prey preferences and predator-prey size relationships were also examined for omnivorous and carnivorous species. Foregut analysis from 2860 individuals indicated opportunistic feeding on the most abundant prey insects, usually in proportion to prey frequency. Feeding preference studies generally indicated random feeding on major prey groups. Prey and predator sizes were usually highly correlated (p<0.01), with predators expanding their prey size thresholds with growth. The potential for competition between sympatric stoneflies for prey is discussed.

A Technique for Increasing the Optical Strength of Single-Crystal NaCl and KCl Through Temperature Cycling (open access)

A Technique for Increasing the Optical Strength of Single-Crystal NaCl and KCl Through Temperature Cycling

This thesis relates a technique for increasing the optical strength of NaCl and KCl single-crystal samples. The 1.06-μm pulsed laser damage thresholds were increased by factors as large as 4.6 for a bulk NaCl single-crystal sample. The bulk laser damage breakdown threshold (LDBT) of the crystal was measured prior to and after heat treatment at 800*C using a Nd:YAG laser operating at 1.06 μm. Bulk and surface LDBTs were also studied on samples annealed at 400° C. These samples showed differences in damage morphology on both cleaved and polished surfaces, and the cleaved surfaces had improved damage thresholds. However, neither the polished surfaces nor the bulk showed improved threshold at the lower annealing temperature.

An Investigation of Food Patterns and Defecation Habits of Texas Latter-Day Saint Adult Males

The objective of this study was to investigate food consumption frequency patterns, defecation habits, and incidence of disease states associated with colon cancer by active LDS adult males, residing in Texas, which may help explain the lower incidence of colon cancer observed in the religious group. To accomplish this objective, a sample of 50 was randomly selected and administered a questionnaire, designed to gather information covering personal and demographic characteristics, defecation habits, incidence of associated disease states, and frequency of consumption of 132 selected foods. Data was analyzed by comparison of percentages, means, and frequencies, and a Pearson Product Moment Correlation. Results reported LDS males chose a wide variety of foods with a high frequency of fruits, vegetables, and cereals. A low incidence of problems associated with colon cancer and "western" or refined diets was also reported. Defecation habits were more frequent than general population and compared favorably to another low-risk population, rural Scandinavians.
