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.

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.

Formulating Stains for use in 08 Temperature Salt Firing (open access)

Formulating Stains for use in 08 Temperature Salt Firing

I developed twenty-three stains to use in low-temperature salt firing for my work. The stains that i made were compared to the commercially made stains to determine the similarities and differences. I felt that after much experimentation using a variety of different oxides in different amounts and calcining these amounts together in an electric kiln (heating the oxides up to about 1733 degrees Fahrenheit) that I was able to produce stable and consistent stains.

Triangle: A Teaching Program of High School Geometry

Among the early applications of computers, one can find frequent mention of intelligent instructional systems. Such intelligent instructional systems represent a new generation of learner-based computer aided instruction, preceded in time by the original frame-based systems and an intervening generation of expert-based CAI. The history of CAI is characterized by three generations: Frame-based CAI, Expert-based CAI and Learner-based CAI.

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.

Initial Starting Posture and Total Body Movement-Reaction Time for Lateral Movement (open access)

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.

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.

Normative Assessment Technique for Bench Press and Leg Extension Strength in College Females on the Universal Gym (open access)

Normative Assessment Technique for Bench Press and Leg Extension Strength in College Females on the Universal Gym

This study was to develop normative data of isotonic muscular strength in college females using the Spartacus model Universal Gym bench press and leg extension and to control for the influence of body weight. Two hundred and two college age females enrolled in weight training and conditioning classes used the Universal Gym for twelve weeks. Subjects were tested for maximum strength on 2 exercises and their percent body fat was calculated. Pearson-product moment correlations between lean body weight , body weight and the bench press test and the leg extension test were correlated. After statistically controlling for the effects of body weight, percentile ranks were calculated for both tests.

The Acute Effects of Intermittent Running on Serum CK and LDH Enzyme Activities in Runners and Non-Runners (open access)

The Acute Effects of Intermittent Running on Serum CK and LDH Enzyme Activities in Runners and Non-Runners

Acute effects of repeated sprinting upon serum creatine kinase (CK), lactic dehydrogenase (LDH), and isozymal activities were studied in five collegiate runners (R_s) and six non-runners (NR_s ). After an intermittent running treadmill test, blood sampling showed three-fold mean increases in CK with no change in LDH in both groups; group differences were insignificant (p>.05). Results suggest (1) intense anaerobic exercise produces moderate enzyme elevations; (2) relatively equivalent exercise intensities are critical to enzyme responses in exercising individuals of varying fitness levels; and (3) exercise-induced enzyme release may be consequential to muscle cell membrane permeability changes from decreased intracellular high-energy phosphates.

Chronomorphosis (open access)

Chronomorphosis

Chronomorphosis is a chamber ensemble piece for flute, clarinet, viola, cello, piano, and percussion. The work, comprising three movements is approximately fourteen minuted in duration. One of the most apparent characteristics of the work is its progression from non-metrical time organization involving aleatoric elements to metrical time organization involving changing meters but no aleatoric elements. The Pitch set is a constant element throughout the piece. The instrumentation selected exhibits a variety of color in all ranges: the flute in the upper register, the clarinet, viola, and vibes in the middle register, and the cello and the timpani in the lower register, the piano having access to all registers.

A Comparison of Sight Word and Phonics Contingencies in the Remediation of Oral Reading and Comprehension (open access)

A Comparison of Sight Word and Phonics Contingencies in the Remediation of Oral Reading and Comprehension

A comparison of contingent word and phonics drilling exercises on oral reading errors was made and the effects of a work skipping contingency on reading comprehension were examined. Five learning disabled elementary school children served as subjects. Reading comprehension increased from 30 to 50% over baseline, while subjects progressed an average of two years through a reading series. Subjects responded differentially to the two drills on oral reading errors, but the combined effects of the drills produced a 50% average reduction in errors. Pre- and post-tests of reading achievement showed increases in reading grade levels ranging from .8 to 1.5 years during the 10 week, 30 session study. Results supported the efficacy of a behavioral approach to reading remediation.

A Study of the Effectiveness of Four Competing Scenarios in Explaining the Causes of Stagflation (open access)

A Study of the Effectiveness of Four Competing Scenarios in Explaining the Causes of Stagflation

This study investigates the relationship between stagflation and price stability and full employment and four economic scenarios and the economic condition. The data used in the study were obtained from government publications and were analyzed using hierarchical multiple regression. The standard inferential apparatus were employed. Give independent variables were found to be significant in explaining the causes of stagflation. These were: absolute change in M1, oil embargo of 1974, corporate profits, output per hour, and Iranian crisis of 1979. In conclusion, the causes of economic instability do not rest with one single theory or factor, but a combination of several.

Studies on the Purification and Phosphorylation of Phosphofructokinase from Ascaris suum (open access)

Studies on the Purification and Phosphorylation of Phosphofructokinase from Ascaris suum

A new procedure has been developed to concentrate the phosphofructokinase from muscle of Ascaris suum with minimum loss of activity. By utilizing this method, 50 ml fraction was concentrated to a final volume of 3 ml in about 1.5 h without loss in enzyme activity. The concentrated enzyme had a specific activity of 64 units per mg. Ascaris muscle-cuticle was incubated in 50 1M solutions of either acetylcholine, serotonin, y-aminobutyric acid, levamisole, or saline alone. Phosphate analysis of the isolated phosphofructokinase from each incubation revealed that the enzyme contained the following moles of phosphate per subunit: 2.9 (acetylcholine), 2.2 (serotonin), 2.0 (y-aminobutyric acid), 1.5 (levamisole), and 3.4 (salne alone). The present study did not establish a direct correlation between degree of phosphorylation and phosphofructokinase activity. Phosphofructokinase from muscle of Ascaris suum appears to contain several phosphorylation sites, and one of these sites is required to be phosphorylated in order for the enzyme to exhibit maximum activity under physiological conditions.

Newspaper Editor Attitudes Toward Matters Involving Privacy (open access)

Newspaper Editor Attitudes Toward Matters Involving Privacy

The primary purpose of this study is to determine whether there has been a change in attitude of newspaper editors toward privacy matters. The study examines a 1976 survey of editors on some specific situations involving privacy and compares that survey with one done for this paper in the spring of 1983. The study also seeks to determine whether such factors as circulation size, type of readership and political philosophy have any influence on privacy decisions made by editors. The study shows that there has been a change in attitudes. A chi square test showed that the comparison of the two surveys was significant at .01. Figures gathered to determine influences on privacy decisions were scattered among many categories and too small to be statistically significant.

Impact of the 1965 Immigration Act on Countries of Origin and Occupational Groups of the International Migrants to the United States (open access)

Impact of the 1965 Immigration Act on Countries of Origin and Occupational Groups of the International Migrants to the United States

The purpose of this research is to investigate the changes in countries of origin and occupational groups of immigrants to the United States after the implementation of the 1965 Immigration Act. The basic policy change in the 1965 Immigration Act was essentially the abolition of the National Origins Quota System. The new law led to obvious changes in the origins of immigrants. The number of Southern European, Asian and Caribbean immigrants significantly increased since the implementation of the Act. The sources of the various occupational groups shifted to some extent. The number of immigrants in the professional and highly skilled categories increased significantly. The impact of the changes aggravated the "brain drain" problem.

A Study of Movement and Countermovement Organizations in the Abortion Movement (open access)

A Study of Movement and Countermovement Organizations in the Abortion Movement

This study begins to fill the gap in sociological literature on movements and countermovements by exploring the dynamic environment of two movement organizations. After documenting the climate of public opinion on abortion, it investigates the strategy and tactics employed by a movement to maintain that opinion and a countermovement to reverse that opinion. It relates social movements to their social environments, social change, opposition, and strategy and tactics. It illustrates the efficacy of single-issue groups in the American social and political environment. Finally, this thesis demonstrates the validity of exploratory studies by uncovering elements of social movements and countermovements that had not been previously investigated.

The Development of Television Broadcasting in Taiwan, The Republic of China (1949-1982) (open access)

The Development of Television Broadcasting in Taiwan, The Republic of China (1949-1982)

This study reviews the evolution of television broadcasting in Taiwan from 1949 to 1982, with emphasis on the period from 1970 to 1982. The problem was to examine the development of the television industry in Taiwan as influenced by law and regulation, politics, and social customs. This study concludes that the development of the television industry in Taiwan was indeed greatly influenced by the above three factors. Future growth of the industry, however, may be greatly hindered unless the government relaxes its close control of the medium in the future.

Relationship Between Self-Efficacy and Academic Behavior Among Students at an Alternative High School (open access)

Relationship Between Self-Efficacy and Academic Behavior Among Students at an Alternative High School

For many years, educators and psychologists have attempted to define the strength of the relationship between self-concept and school performance., A productive approach may be to investigate academic self-efficacy. In the present study, data were collected for students at an alternative high school on the Measure of Academic Self-Efficacy (MASE), Intellectual Achievement Responsibility Questionnaire (IAR), number of weeks spent in the program, and various descriptive and behavioral measures. Correlations were computed to attempt to demonstrate that participation in an alternative program analogous to participant modeling is associated with increases in academic self-efficacy and internal attributions for educational events, and that these gains are associated with improved academic outcomes.

Artistic Vibrato and Tremolo: A Survey of the Literature (open access)

Artistic Vibrato and Tremolo: A Survey of the Literature

This investigation surveys pertinent literature, from 1917 to 1982 inclusive, regarding artistic vibrato and tremolo in singing. The contents are subdivided into individual investigative reports by various vocal researchers. Due to mounting confusion within the amassed literature, the need for systematic organization and evaluation is evident. Misunderstandings within the context of the literature and misnomers within the terminology require clarification and resolution. The evaluation intends to produce a proper perspective on vibrato and tremolo, eradicating some of the confusion surrounding the terms. Artistic vibrato is recognized as a desirable component in Western vocal music. In contrast, tremolo is deemed a deviant vibrato, i.e., a vibrato which deviates from artistic norms. The study attempts to clarify the distinguishing traits of these two vocal phenomena.

Optimization of High Performance Liquid Chromatographic Separations (open access)

Optimization of High Performance Liquid Chromatographic Separations

This study had a twofold purpose. First, the usefulness of the simplex algorithm as a short method of optimization in high performance liquid chromatographic separations was investigated. The second was to test a modified simplex method. The volume fractions of mobile phase components were chosen as the variable factors in the optimization process. Four test cases were performed which included separation of cholesterol esters, naphthalene and its derivatives, polycyclic aromatic compounds, and the thiane compounds. The standard for accepting an optimum was based on the baseline separation of two adjacent peaks and the analysis time. In addition to successful separations, the correlation between the separation and the chemical characteristics of mobile phase compositions was calculated and this could then be used for further modification of simplex search strategy.
