A Study of the Anti-Catholic Bias Contained Within Jacob Burckhardt's The Civilization of the Renaissance in Italy
This work examines the anti-Catholic bias of Jacob Burckhardt as he employed it in the Civilization of the Renaissance in Italy. A biographical chapter examines his early education in the Lutheran seminary and the influence of his educators at the University of Berlin. The Civilization is examined in three critical areas: Burckhardt's treatment of the popes in his chapter "The State as a Work of Art," the reform tendencies of the Italian humanists which Burckhardt virtually ignored, and the rise of confraternities in Italy. In each instance, Burckhardt demonstrated a clear bias against the Catholic Church. Further study could reveal if this initial bias was perpetuated through later "Burckhardtian" historians.

Knowing is Seaing: Conceptual Metaphor in the Fiction of Kate Chopin
This paper examines the metaphoric structures that underlie Chopin's major novel, The Awakening, as well as those underlying selected short stories. Drawing on the modern theory of metaphor described by Mark Turner, George Lakoff, and Mark Johnson, the author argues that conceptual metaphors are the structural elements that underlie our experiences, thoughts, and words, and that their presence is revealed through our everyday language. Since these conceptual structures are representative of human thought and language, they are also present in literary texts, and specifically in Chopin's texts. Conceptual metaphors and the linguistic forms that result from them are so basic a part of our thinking that we automatically construct our utterances by means of them. Accordingly, conceptual metaphor mirrors human thought processes, as demonstrated by the way we describe our experiences.

College Students' Preference of Computer Input Device: Keyboard versus Mouse
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.

A Structural Approach to Four Theories of Group Development
The goal of this study was to attempt to develop a classification scheme that systematically related individual behavior, interpersonal behavior, and group interactions for the purpose of using the resulting classification scheme to evaluate theories of group development proposed by Bion, Bennis and Shepard, Bales, and Tuckman and Jensen. It was assumed that theorists' presuppositions about the structure of groups might influence their theories. Using a qualitative process of analysis, a structural classification scheme (SCS) was developed based upon transformative and generative rules, utilizing the General System Theory subsystem process of self-regulated boundary operations. The SCS protocol was employed to categorize and compare the theories of group development proposed by Bion, Bennis and Shepard, Bales, and Tuckman and Jensen. The resulting categorization of theories indicated that relationships existed among and between a group's structural properties, the complexity and type of communication connections among and between group members, and the size of the group. In addition, a common structural relationship was demonstrated to exist among and between individual, dyadic, and triadic group forms. A similar structural relationship was also speculated to exist between groups of any size. It was concluded that a structural approach to groups may offer insight to group …

The Effects of Project PACE on Adolescent Females' Physical Activity Readiness
This study evaluated the effects of Project PACE, a program designed to increase physical activity, on the physical activity level and selected psychosocial variables of sedentary adolescent females ages 12 to 18. Psychosocial variables included self efficacy, attitude, perception of barriers, perceived social support, and knowledge. Of the 69 participants, 40 were enrolled in the treatment group and 29 were enrolled in the control group at the start of the study. The only significant differences were found for attitudes towards physical activity at base line. Findings from this study suggest that implementation of Project PACE protocol in school settings may produce some positive effects, but no significant findings were detected.

Was Ist Silvia? Englanderin Oder Deutsche? Restoring the Orignial English Texts to Songs Schubert Set in Translation, a Lecture Recital, Together with Three Recitals of Selected Works of H. Purcell, G. F. Handel, W. A. Mozart, F. Schubert, J. Brahms, H. Wolf, F. Poulenc and Others
Because of the lack of information concerning the success or failure of Schubert's bilingual edition and concerning the relationship between the English texts and Schubert's settings, most performers take the conservative route of performing both the songs from Lady of the Lake and the rest of Schubert's English song repertoire only with the German translations. Because of the desirability of performing this repertoire in English for English-speaking audiences, this study examines all of the English songs of Schubert to determine whether the original poems can be successfully substituted for the German translations. Editions of the settings that can be effectively performed with the English texts are included in the appendix, in order to make available editions which reflect Schubert's ambition to make his songs easily accessible to non-German-speaking audiences.

Construction of a Physical Map of Moraxella (Branhamella) catarrhalis Strain ATCC25238
In order to gain a better understanding of this microorganismand its role in human pathogenesis, a physical map of Moraxella catarrhalis type strain ATCC25238 was constructed using pulsed field gel electrophoresis (PFGE) in combination with Southern hybridization techniques. Restriction endonucleases Not I, Rsr II, and Sma I were used to digest the chromosomal DNA. An overlapping circular map was generated by cross-hybridization of isolated radiolabeled fragments of Moraxella catarrhalis genomic DNA to dried PFGE gels. The number and location of the 16S and 23S ribosomal RNA genes were determined by digestion with l-Ceul enzyme and by Southern hybridization. Virulence-associated genes, the gene for β-lactamase, and housekeeping genes were also placed onto the physical map.

The Effects of Alternative Presentation Formats on Biases and Heuristics in Human Decision Making
The purpose of this research was to determine whether changes in the presentation format of items in a computer display could be used to alter the impact of specific cognitive biases, and to add to the knowledge needed to construct theory-based guidelines for output design. The problem motivating this study is twofold. The first part of the problem is the sub-optimal decision making caused by the use of heuristics and their associated cognitive biases. The second part of the problem is the lack of a theoretical basis to guide the design of information presentation formats to counter the effects of such biases. An availability model of the impact of changes in presentation format on biases and heuristics was constructed based on the findings of a literature review. A six-part laboratory experiment was conducted utilizing a sample of 205 student subjects from the college of business. The independent variable was presentation format which was manipulated by altering the visual salience or visual recency of items of information in a visual computer display. The dependent variables included recall, perceived importance, and the subjects' responses to three judgment tasks. The results clearly demonstrate that changes in presentation format can be used to alter …

Rollback Reduction Techniques Through Load Balancing in Optimistic Parallel Discrete Event Simulation
Discrete event simulation is an important tool for modeling and analysis. Some of the simulation applications such as telecommunication network performance, VLSI logic circuits design, battlefield simulation, require enormous amount of computing resources. One way to satisfy this demand for computing power is to decompose the simulation system into several logical processes (Ip) and run them concurrently. In any parallel discrete event simulation (PDES) system, the events are ordered according to their time of occurrence. In order for the simulation to be correct, this ordering has to be preserved. There are three approaches to maintain this ordering. In a conservative system, no lp executes an event unless it is certain that all events with earlier time-stamps have been executed. Such systems are prone to deadlock. In an optimistic system on the other hand, simulation progresses disregarding this ordering and saves the system states regularly. Whenever a causality violation is detected, the system rolls back to a state saved earlier and restarts processing after correcting the error. There is another approach in which all the lps participate in the computation of a safe time-window and all events with time-stamps within this window are processed concurrently. In optimistic simulation systems, there is …

An Empirical Investigation of Detail Design Tools and Cognitive Style of Software Developers
The purpose of this study is to identify what detail design tools are more productive for the different types of professional software developers. By establishing a match between the detail design tool and the cognitive style of the professional programmer, the end product (Information Systems) should be of a higher quality. Two laboratory experiments were conducted. The first experiment was with professional Software Developers; the second one was with students. The dependant variables considered in this study were the number of semantic errors and the time required to complete a design task for conditional logic. The independent variables were the cognitive style of the subject, the complexity of the task, and the detail design tools. Decision trees, flowcharts and pseudocode were used as detailed design tools. Field dependence was the only dimension of cognitive style that was tested.

Motion Versus Non-Motion in Interactive Video Lessons in High School Physical Science
The most important question addresed in this study was whether there is any difference in student learning between a motion group and a non-motion group. The interactive video courseware is currently a part of the curriculum in this district. It was used in its original form with the contrast group. For the experimental group one unit of the courseware was modified to remove the motion video and replace it with photorealistic graphics that served as the non-motion part of the study. Covariates were selected to compensate for any differences in the two groups. A pretest and posttest was administered to both groups. Analysis of the posttest scores indicated that there was no difference in learning if motion in the presentation was the only variable.

Structure and Performance of El Polifemo de Oro for Solo Guitar by Reginald Smith Brindle
El Polifemo de Oro was written in 1956 and revised by the composer in 1981. This two-fold investigation clarifies the structure of El Polifemo through careful analysis of the work and its revision, and by Smith Brindle's approach to composition based on his interviews and books. The second aspect is aimed toward the pragmatic performance issues of tempo, articulation, timbre, voice leading, and the other details of execution. Although the work was written according to serial techniques, the presence, in the twelve-note row, of triadic formations (minor triad, dominant seventh, fully-diminished seventh) juxtaposed with many tritone intervals suggests the use of tonal devices, which Smith Brindle does employ to effect tension and relaxation. It is assumed that tonal devices such as leading tones, stepwise movement in the bass, fourth and fifth relationships, and triadic constructions are heard against a traditional contextual basis and are therefore ways of implying resolution. Where tonal devices are not present, other structural components, i.e., rhythm, dynamics, timbre, etc., are examined with regard to their functions in creating or dissipating tension. Following the analysis of each of the four fragments is a discussion of performance implications based on the analysis. Both the analysis and performance aspects …

A Comparison of Predicted and Actual Trophic Status of Lake Ray Roberts, Texas Based on Chlorophyll A
Two years before impoundment, the trophic status of Lake Ray Roberts was predicted by applying the total phosphorus input into the Organization for Economic Cooperation and Development (OECD) eutrophication model. Predicted mean summer epilimnetic (MSE) chlorophyll a of Elm Fork arm, Isle duBois arm and Main Body were in the eutrophic category of the OECD model. Observed MSE chlorophyll a two years after impoundment of Elm Fork arm, Isle duBois and Main Body had not reached their predicted means and were at the mesotrophic-eutrophic boundary of the OECD model. Six years after impoundment, observed MSE chlorophyll a for Main Body, was closer to its predicted mean and in the eutrophic category of the OECD model. Six years after impoundment, Elm Fork arm was the most productive area of Lake Ray Roberts. Observed means of chlorophyll a, total phosphates, suspended solids and turbidity were often highest in the Elm Fork arm. Wastewater effluent from Gainesville and Valley View, TX, had an impact on productivity in Elm Fork arm.

A Laboratory Study of the Asiatic Clam (Corbicula fluminea Müller) as Influenced by Substrate, Food Source and Water Type
Growth of Corbicula fluminea was monitored in the laboratory. Three experiments were conducted. Experiment I utilized three substrates and one food type. Experiment II utilized three substrates and two food types. Experiments I and II were conducted to determine if substrate type or food type effected growth. Experiment III used no substrates, one food type and was conducted to determine growth response to different types of water. Clams were maintained in three substrates: sand, gravel and clay. Clams were also maintained without substrate. Growth was monitored by measuring shell length (mm) and recording the weight (mg) of clams over a period of thirty days. At the end of the test period data were evaluated for normality and homogeneity.

A Study of the Influence of Kenneth Cooper's Work on the Teaching of Wellness and Fitness in Physical Education Programs in 2-Year Community Colleges in the United States
Kenneth H. Cooper is considered to be a noted scholar in the field of wellness and fitness. This study explored his contributions to the preventive medicine and wellness movement in community college physical education programs in the United States. It examined Cooper's influence on the development of preventive medicine and wellness from its inception and growth to its impact on changes and factors affecting curriculum in community college programs. A random sample of436 physical education division directors from the nation's 1,400 community colleges yielded a 62% survey response. For purposes of comparison, the sample was stratified into two regions taken fromeast and west of the Mississippi River. Chi-square analysis at the .01 level of significance found no difference between variables due to geographic region. The findings of this study indicate that Kenneth Cooper's contributions to preventive medicine and wellness in community college physical education curriculum are overshadowed by state and local governing bodies that are the force behind curricular development in the nation's 2-year community colleges. However, as an individual contributor, Cooper ranks highly in influencing the wellness and physical education curriculum primarily in the areas of aerobic exercise, physical fitness, and cardiovascular disease. The extent of Cooper's impact on …

Diagnosing Learner Deficiencies in Algorithmic Reasoning
It is hypothesized that useful diagnostic information can reside in the wrong answers of multiple-choice tests, and that properly designed distractors can yield indications of misinformation and missing information in algorithmic reasoning on the part of the test taker. In addition to summarizing the literature regarding diagnostic research as opposed to scoring research, this study proposes a methodology for analyzing test results and compares the findings with those from the research of Birenbaum and Tatsuoka and others. The proposed method identifies the conditions of misinformation and missing information, and it contains a statistical compensation for careless errors. Strengths and weaknesses of the method are explored, and suggestions for further research are offered.

Scaling Behaviors and Mechanical Properties of Polymer Gels
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.

Analysis of Thermoplastic Polyimide + Polymer Liquid Crystal Blends
Thermoplastic polyimides (TPIs) exhibit high glass transition temperatures (Tgs), which make them useful in high performance applications. Amorphous and semicrystalline TPIs show sub-Tg relaxations, which can aid in improving strength characteristics through energy absorption. The a relaxation of both types of TPIs indicates a cooperative nature. The semicrystalline TPI shows thermo-irreversible cold crystallization phenomenon. The polymer liquid crystal (PLC) used in the blends is thermotropic and with longitudinal molecular structure. The small heat capacity change (ACP) associated with the glass transition indicates the PLC to be rigid rod in nature. The PLC shows a small endotherm associated with the melting. The addition of PLC to the semicrystalline TPI does not significantly affect the Tg or the melting point (Tm). The cold crystallization temperature (Tc) increases with the addition of the PLC, indicating channeling phenomenon. The addition of PLC also causes a negative deviation of the ACP, which is another evidence for channeling. The TPI, PLC and their blends show high thermal stability. The semicrystalline TPI absorbs moisture; this effect decreases with the addition of the PLC. The absorbed moisture does not show any effect on the degradation. The addition of PLC beyond 30 wt.% does not result in an improvement …
