In the last several years, there has been an interest in graphical user interfaces as compared with character user interfaces. The "mouse" is the device most closely associated with graphical user interfaces. Key strokes are more closely associated with character user interfaces. Given these associations, is there a preference for the keyboard or for the mouse as an input device? The determination of user preference was reduced to the determination of preference of key strokes or mouse clicks for selection of main menu items. The subjects, university students working with Microsoft Works by Microsoft Corporation, copyright 1987-1989, were learning how to use application software. While Microsoft Works was running, tracking software recorded every user key stroke and mouse click, together with data about these key strokes and mouse clicks. From the analysis of these data, common preference for the means of menu item selection was determined.

Polymer gels undergo a volume phase transition in solvent in response to an infinitesimal environmental change. This remarkable phenomenon has resulted in many potential applications of polymer gels. The understanding of its mechanical properties has both scientific and technological importance. For this purpose, we have developed a novel method for measuring Poisson's ratio, which is one of the most important parameters determining the mechanical property of gels. Using this method, Poisson's ratio in N-isopropyacrylamide (NIPA) and polyacrylamide (PAAM) gels has been studied.

Age/cohort differences in several aspects of the self-system were investigated utilizing a sentence completion paradigm. Eighty-eight adults over age sixty and one hundred eight adults under age forty served as subjects. Subjects were asked to complete 30 self-referent sentence stems which were pre-structured to elicit information from the self-system. Responses were subjected to a content analysis utilizing a coding system which contained concepts used by subjects in their self-representations. Contents were coded for dimensions conceptually related to Physical Health, Autonomy, Self-Evaluation, Depression, Spirituality, and Altruism. Frequencies of codings were counted and subjected to statistical analysis for performing age group comparisons.

IS outsourcing, especially large-scale IS outsourcing, is a comparatively recent and rapidly growing IS phenomenon, but it is also an inherently risky activity. In an IS outsourcing arrangement, the outsourcing vendor accepts responsibility for IS resources and functions formerly controlled directly by the firm. This research examines IS outsourcing from two perspectives. (1) From an IS perspective, it examines the risk perceptions of IS managers of fourteen Fortune-500 firms who had recently conducted an outsourcing evaluation. (2) From a financial perspective, it examines the theoretical relationship of IS outsourcing with financial performance, and investigates the empirical effects of IS outsourcing on the firm's market value and market risk. This research views IS outsourcing as an independent variable whose effects on the firm may be measured as changes in security returns, changes in asset risk, changes in capital structure, and long-term changes in profitability. To accomplish this, it characterizes IS outsourcing as a sale-and-leaseback transaction.

Significant passages in Alice Walker's writings give evidence of archetypal patterns from Carl Jung and feminine archetypal patterns from Annis Pratt. Since a knowledge of archetypal patterns can influence the total understanding of aspects of Walker's writings, a study of these patterns in the undergraduate classroom benefits the student and opens up another system of analyzing writings, particularly writings by African-American women.

The problem of this study was to determine the effects of implementing writing-to-learn tasks in mathematics instruction on fourth grade students' achievement and attitude toward mathematics. Also addressed in this study is whether or not achievement and attitude measures of female students and low achieving students are effected by the use of writing in mathematics.

A number of protein kinases have been shown to undergo autophosphorylation, but few have demonstrated a coordinate increase or decrease in enzymatic activity as a result. Described here is a novel S6 kinase isolated from human placenta which autoactivates through autophosphorylation in vitro. This S6/H4 kinase, purified in an inactive state, was shown to be a protein of Mr of 60,000 as estimated by SDS-PAGE and could catalyze the phosphorylation of the synthetic peptide S6-21, the histone H4, and myelin basic protein. Mild digestion of the inactive S6/H4 kinase with trypsin was necessary, but not sufficient, to activate the kinase fully

This study uses concurrent verbal protocol analysis to examine the decision processes of lenders as they evaluate the financial information of a loan applicant. Of specific interest is the lenders' use of Statement of Financial Accounting Standards Board No. 95 (FAS 95), Statement of Cash Flows, in that decision process.

This empirical study is aimed at understanding the patterns of relationships among the organization structure of self-managed work teams in terms of three sets of constructs: 1. organization-based self-esteem; 2. consequent behaviors of intrinsic work motivation, general job satisfaction, organization citizenship, and organization commitment; and 3. performance. The primary significance of this study is that it adds to the pool of empirical knowledge in the field of self-managed work team research. The significance of this study to practicing managers is that it can help them make better-informed decisions on the use of the self-managed work team structure. This study was a sample survey composed of five standardized questionnaires using a five-point Likert-type scale, open-ended questions, and demographic questions. Unstructured interviews supplemented the structured survey and for means of triangulation of results. The variables were analyzed using regression analysis for the purpose of path analysis. The site was a manufacturing plant structured around self-managed work teams. The population was full-time, first-line production employees.

The purpose of this study is to describe the history, development, problems, and issues related to achieving university status of South-East Asia College from 1974 to 1993. This historical research used records and documents from South-East Asia College and the Association of Private Higher Education Institutions of Thailand as primary sources. Also interviews with the president, faculty and staff of South-East Asia College were used. Secondary Sources were reports and publications from the Ministry of University Affairs in Thailand. The areas of emphasis in the study were government policies on private higher education, legislation that initiated the founding of the college, the founder, the college's goals, financial sources, curriculum, library, faculty, students, and buildings. It was found that the Thai government encourages the establishment of private higher education institutions. The Private Higher Educational Institution Act of 1979 was enacted to allow private universities to be equal to government universities. South-East Asia College was founded in 1974 by the Khunya Plak Muanpiew Foundation with the purpose of training Thai students for industrial technologies and business sectors. The college requested university status in April, 1987. The first attempt was turned down. Four areas not meeting the requirements were the library, faculty, students, …

Standardized tests are being administered to young children in greater numbers in recent years than ever before. Many more important educational decisions about children are being based on the results of these tests. This practice continues to escalate despite early childhood professional organizations' calls for a ban of standardized testing for children eight years of age and younger. Many early childhood educators have become dissatisfied with multiple-choice testing as a measure of student learning and are increasingly using various forms of alternative assessment to replace the more traditional testing formats. Teachers seem to be caught in the middle of the controversy between standardized testing and alternative assessment. This research examined what early childhood educators in one north Texas school district believe about assessment of young children and what assessment methods they report using in their classrooms, as well as factors which influence those beliefs and practices. The sample for this study was 84 teachers who taught prekindergarten through third grade. An eight-page questionnaire provided quantitative data and interviews and the researcher's journal provided qualitative data.

These poems deconstruct Mary Shelley's monster from a spiritually Chthonian, critically post-structuralist creative stance. But the process here is not simple disruption of the original discourse; this poetry cycle transforms the monster's traditional body, using what pieces are left from reception/vivisection to reconstruct, through gradual accretion, new authority for each new form, each new appendage.

Graduate students in the College of Education at the University of North Texas, Denton rated 57 teacher attributes on their relative importance in effective teaching. The data was analyzed across six demographic variables of department, sex, degree, nationality, teaching experience, and previous graduate school, using mean scores, one-way ANOVA, and t-tests for two independent samples.

The purpose of this dissertation is to examine the effects of activity-based costing (ABC) and activity-based management (ABM) on managerial and employee behavior.

This study examined the influences of a variety of verbal and non-verbal strategies on the language acquisition of six fourth grade ESL students in a discipline-based art education classroom. The art teacher/researcher spoke only English, and the students spoke Spanish almost exclusively. The art instruction occurred during eighteen 30 minute sessions, over a period of five months. The program involved the whole language approach, collaborative/cooperative learning, and the study of art concepts through verbal and graphic symbol cue cards and images of art works. Data were amassed from transcripts of video recordings, student and teacher interviews, and reflective notes. This study showed highly successful results with student growth in language acquisition and comprehension of art concepts.

This thesis examines the evolution of beams in synchrotrons. Following an introduction to accelerator physics in Chapter 1, in Chapter 2 I describe the Fermilab E778 'diffusion' experiment. Families of sextupoles were powered to drive the 2/5 resonance, and a beam was then kicked to populate a nonlinear region of the transverse phase space. The beam was then observed over periods of approximately 30 minutes for a variety of kick amplitudes and physical apertures. In Chapter 3 comments about the analytic treatment of such systems are discussed, including the assumptions inherent in the conventional treatment. I motivate my use of a simplified model in Chapter 4 after examining common computational methods. Deriving the model from the formalism of traditional accelerator physics, I discuss its implementation on a massively parallel computer, the Intel iPSC/860 hypercube, and examine the performance of this algorithm in detail. Using the simple model to perform the numerical experiment equivalent to E778 is the subject of Chapter 5. I derive the parameters needed for the simple model based upon the physical experiment. Both three dimensional cases and cases with reduced dimensionality are run. From power supply ripple data and an electrical model of the magnet string, I …

The purpose of this study was to assess on a national level, high school band directors' reasons for their bands' participation in six different types of competitive music activities, identify important reasons for participation in competitive music activities, and examine if statistically significant differences existed between the magnitudes of importance reasons for participation when subjects' responses were grouped by type of competitive activity, frequency of participation in a competitive activity, and by groupings of U. S. states similar in terms of general participation in competitive music activities, emphasis upon ratings or rankings as an indication of a high school band directors' success, and emphasis upon participation in competitive music activities.

Recent Berlioz studies tend to stress the significance of the French tradition for a balanced understanding of Berlioz's music. Such is necessary because the customary emphasis on purely musical structure inclines to stress the influence of German masters to the neglect of vocal and therefore rhetorical character of this tradition. The present study, through a fresh examination of Berlioz's vocal-orchestral scores, sets forth the various orchestrational patterns and the rationales that lay behind them.

This study extended research on the influence of counselor Christian values on the client's perceptions of the counselor by adding consensus values to the description of the counselor and examining the effects of age and religious maturity of the client. Subjects consisted of two samples, one of 250 undergraduate students (younger group) and the other of adults of at least thirty-five years of age (older group). There were equal number of males and females in each group. Subjects read one of five descriptions of a counselor, which varied according to the religious values of the counselor, and then rated the counselor. The following instruments were used to rate the counselor: Counselor Rating Form, Confidence in Counselor's Helpfulness Scale, Willingness to Meet the Counselor Scale and the Similarity of Values and Opinions Scale. The religiosity of the subjects was measured with the Religious Orientation Scale, the Christian Orthodoxy Scale and the Religious Status Inventory. The major premise of the study that the Christian values of the counselor influence the client's perceptions of the counselor as the client increases in age and religious maturity was partially supported. A significant counselor Christian value by age interaction was obtained in which the older subjects …

Johann Joseph Fux's influence on the development of eighteenth-century alto trombone literature is significant. His music, when compared with that of other composers who wrote for the alto trombone before 1730, reveals a more elaborate and frequent use of the instrument. Many of Fux's compositions call for alto, tenor, or bass trombone, but his Sonata a Quattro K. 347 and Alma Redemptoris Mater K. 186 are of particular interest in regard to the composer's treatment of the alto trombone. This study points out the technical demands placed on the trombonist in Fux's works as compared to such contemporary composers as Antonio Caldara and Marc'Antonio Ziani. The primary goal of this study is to substantiate the importance of Fux's role in the development of the alto trombone repertoire. Published and unpublished works by Fux that significantly incorporate the instrument have been studied and compared to compositions of his contemporaries. A thorough discussion of Sonata a Quattro and Alma Redemptoris Mater illustrates the technical aspects of his alto trombone writing. The secondary goal of this study is to create a performing edition of Sonata a Quattro and Alma Redemptoris Mater. The existing editions in Denkmaler der Tonkunst in Osterreich and Johann Joseph …

The nonlinear dynamics of three physical systems has been investigated. Diode resonator systems are experimentally shown to display a period doubling route to chaos, quasiperiodic states, periodic locking states, and Hopf bifurcation to chaos. Particularly, the transition from quasiperiodic states to chaos in line-coupled systems agrees well with the Curry-Yorke model. The SPICE program has been modified to give realistic models for the diode resonator systems.

This dissertation is a study of the romantic elements in Bernard Malamud's fiction that can be seen as representing a romantic ideology closely related to the romanticism of William Wordsworth.

This study investigated relationships among and between psychological hardiness, coping style, and burnout in 101 female hospital nurses. The third generation (50-item) hardiness scale, scored by the revised scoring procedure, was used to measure hardiness and its components. The Maslach Burnout Inventory was used as the measurement for burnout. Coping style was assessed by the COPE Inventory. The components of hardiness, commitment, control, and challenge, were hypothesized to be negative predictors of emotional exhaustion and depersonalization and positive predictors of personal accomplishment. In addition, hardiness and its components were postulated to be positively related to adaptive coping styles and negatively related to maladaptive coping styles. Emotional exhaustion and depersonalization were thought to be related positively to maladaptive coping styles and negatively related to adaptive coping styles. Personal accomplishment was thought to be positively related to adaptive coping style and negatively related to maladaptive coping style. Simple and multiple regressions were used.

In comparing the means .of two normally distributed populations with unknown variance, two tests very often used are: the two independent sample and the paired sample t tests. There is a possible gain in the power of the significance test by using the paired sample design instead of the two independent samples design.
