The purpose of this experiment was to evaluate the effects of alternative contingencies on instruction following by an ABA design. Three college students consistently pressed keys 1-5-3 and 4-8-6 in the presence of the written instruction "Press 153" or "Press 486." During condition A, the contingencies for following and not following the instruction were the same: CON FR5 FR5 and CON FR20 FR20. During condition B, the contingencies for following and not following the instruction were different: CON FR20 FR5. For one participant, the schedule of reinforcement was then changed to FR30. The results showed that subjects followed instructions when the schedule of reinforcement was the same for instruction following and not following.

The recordings of the legendary pianist Ignacy Jan Paderewski are a valuable documentation of his piano performance style. Knowledge of late-Romantic performance practices gleaned from Paderewski's recordings suggest ways of approaching the performance of his Sonata in E-Flat Minor, Op. 21. This Sonata, composed in 1903 near the end of his compositional career, is a work of the highest caliber, deserving a permanent place in the concert pianist's repertoire. The purpose of this paper is to provide performance suggestions based on Paderewski's performance style which will produce a performance closer to the spirit of the times in which it was written. This study provides an overview of the project in Chapter 1, and a background of Paderewski's life as pianist, composer, and statesman in Chapter 2. A time-line chart of his complete works is included for reference. Chapter 3 analyzes Sonata, Op. 21 in regards to form, sound, melody, harmony, and rhythm. Following the analysis, the Sonata is compared compositionally to sonatas that appear alongside Sonata, Op. 21 on Paderewski's programs, including those by Chopin, Beethoven, and Liszt. Graphs summarize the form and dynamic density of the Sonata, and examples illustrate Paderewski's craft at thematic transformation. Chapter 4 examines Paderewski's …

Data warehousing (DW) in the last decade has become the technology of choice for building data management infrastructures to provide organizations the decision-making capabilities needed to effectively carry out its activities. Despite its phenomenal growth and importance to organizations the rate of DW implementation success has been less than stellar. Many DW implementation projects fail due to technical or organizational reasons. There has been limited research on organizational factors and their role in DW implementations. It is important to understand the role and impact of both technical but organizational factors in DW implementations and their relative importance to implementation performance. A research model was developed to test the significance of technical and organizational factors in the three phases of implementation with DW implementation performance. The independent variables were technical (data, technology, and expertise) and organizational (management, goals, users, organization). The dependent variable was performance (content, accuracy, format, ease of use, and timeliness). The data collection method was a Web based survey of DW implementers and DW users sampled (26) from a population of 108 identified DW implementations. Regression was used as the multivariate statistical technique to analyze the data. The results show that organization factors are significantly related to performance. …

Human auditory perception is suited to receiving and interpreting information from the environment but this knowledge has not been used extensively in designing computer-based information exploration tools. It is not known which aspects of sound are useful for accurately conveying information in an auditory display. An auditory display was created using PD, a graphical programming language used primarily to manipulate digital sound. The interface for the auditory display was a blank window. When the cursor is moved around in this window, the sound generated would changed based on the underlying data value at any given point. An experiment was conducted to determine which attribute of sound most accurately represents data values in an auditory display. The four attributes of sound tested were frequency-sine waveform, frequency-sawtooth waveform, loudness and tempo. 24 subjects were given the task of finding the highest data point using sound alone using each of the four sound treatments. Three dependent variables were measured: distance accuracy, numeric accuracy, and time on task. Repeated measures ANOVA procedures conducted on these variables did not rise to the level of statistical significance (α=.05). None of the sound treatments was more accurate than the other as representing the underlying data values. 52% …

Kurt Vonnegut's early science fiction novels depict societies and characters that, as in the real world, have become callous and downtrodden. These works use supercomputers, aliens, and space travel, often in a comical manner, to demonstrate that the future, unless people change their concepts of humanity, will not be the paradise of advanced technology and human harmony that some may expect. In fact, Vonnegut suggests that the human condition may gradually worsen if people continue to look further and further into the universe for happiness and purpose. To Vonnegut, the key to happiness is dignity, and this key is to be found within ourselves, not without.

The objective of this study was to determine how a new experimental methodology for measuring Total-Harmonic-Distortion (THD) of operational amplifiers functioned when compared with two standard methodologies, and whether the new methodology offers any improvement in noise floor and dynamic range along with distortion canceling of the sine-wave source used in the testing. The new methodology (THD) is being tested against two standard methodologies: Spectral Analysis using a tuned receiver type Spectrum Analyzer with Notch Filter pre-processing, and a digitized Fast Fourier Transform (FFT) using Notch Filter pre-processing. The THD results appear to agree across all methodologies, and across all items of the sample within all methodologies, to within a percent or less. The distortion and noise canceling feature of the new methodology appeared to function as expected and in accordance with theory. The sample tested in the study consisted of thirty-five NE5534 operational amplifiers produced by Texas Instruments, Inc. and purchased from a local store. The NE5534 is a low-noise, low-distortion, operational amplifier that is widely used in industry and is representative of today's best audio amplifiers.

The immediate and subsequent effects of different durations of response restriction were evaluated in a multiple schedule design. Response restriction components of 15, 30, and 60 minutes were conducted between 15 minute alone components. Levels of responding subsequent to the termination of response restriction procedures were compared to free operant levels prior to the implementation of response restriction. Responding during response restriction components reduced to near zero levels. Subsequent levels of responding were similar to or exceeded free operant baseline levels. Results are discussed in terms of potential operant mechanisms responsible for levels of responding subsequent to response restriction.

Twenty-first century learners have bought into a cafeteria-style mentality for obtaining higher education that learning should be available at the student's convenience. Institutions that ignore this postmodern trend will likely find their applicant pools dwindling along with significant reductions in entering class sizes. Students will simply choose other schools able to provide respected, accredited, and useful learning which fits their busy lifestyles. Since 1987, Dallas Theological Seminary (Texas), a 76-year-old graduate school of theology in the conservative, evangelical, free-church movement, has offered distance learning classes in both extension and print-based delivery models. Because the faculty plays a pivotal role in the successful or unsuccessful implementation of online courses (McKenzie, Mims, Bennett, & Waugh, 2000), the present study uncovered the attitudes of full-time, graduate theological faculty at Dallas Theological Seminary (DTS) regarding distance learning and the likelihood of faculty to adopt this delivery innovation. Bruce Manning's (1976) Trouble-Shooting Checklist (TSC) for Higher Education Institutions was the instrument used in the study. The TSC is a nonparametric test designed to uncover differences between the observed and expected levels of acceptance that a department, program, or institution possesses regarding change toward distance learning in contrast to residential learning. The checklist's two major purposes …

The purpose of this study was to examine how male and female leaders view their own effectiveness as compared to their objective performance. This study also examined sex and gender differences in subordinate's views of male and female leaders. Forty-two mixed-sex groups led by appointed male and female leaders were observed to assess objective and perceived leader effectiveness. Gender role of participants was assessed using the Bem Sex Role Inventory (BSRI). No sex or gender differences were found in objective leadership effectiveness. An unexpected finding was that male and female leaders perceived themselves accurately as leaders. Significant differences were found in the way male subordinates rated men and women leaders when taking into account gender role. Results indicated that the study of gender bias in leadership is complex and should be examined in conjunction with gender role. Social role theory helps to explain this bias.

A functional analysis, conducted to assess the variables maintaining the chronic eye poking of a female diagnosed with profound mental retardation, indicated that the behavior persisted in the absence of social contingencies. A procedure was initiated in a training environment in which a punisher (mild reprimand) was delivered contingent on eye poking in the presence, but not in the absence, of a neutral stimulus (wristbands). Using a combination of multiple baseline and multielement experimental designs, it was determined that that eye poking was suppressed in the presence of the previously neutral stimulus, even in environments in which the reprimand contingency was inoperative.

Recently my creative process has led to a new area of investigation and exploration. I have discovered that I enjoy the unexpected occurrences that happen while painting. I have an appreciation for the parts of my works that do not follow the preliminary sketch and are produced more subconsciously. While usually this aspect has been restricted by the adherence to a preliminary sketch and narrative, the new works explore these occurrences more fully. In the new works, I worked in a more spontaneous manner to create work that does not focus strictly on narrative but reveals itself more as a journey or exploration.

This study analyzed participants in an online professional development and certification program can to see if they could predict the learning value of individual distance education tools. The Texas Center for Educational Technology (TCET) funded by the Texas Telecommunications Infrastructure Fund (TIF) designed the Technology Applications Certification Program (TACP). In the TACP, students are offered four graduate level classes which, when combined, meet the standards for the State Board for Educator Certification (SBEC) Technology Applications certification. The four courses that comprise the TACP are Computers in Education, Introduction to the Internet, Multimedia in Technology Applications, and Introduction to Video Technologies. The first course started in January 2002 with approximately 706 participants in 40 cohorts across the state of Texas. The TACP combines two different worlds of technology training. Half of the coursework was completed through asynchronous content and discussions, while the remaining classes were hands-on classes in local district computer labs. These face-to-face meetings enabled learners to get hands-on training with direct assistance. Between the online and face-to-face segments, a variety of learning tools were introduced to the participants. Participants were surveyed through the online Snapshot Survey in January and again in September.

This study was designed to examine how four-year-old children might be able to respond and interpret works of art. Informed by Jean Piaget's and Lev Vygotsky's theories of cognitive development, and building on Micheal Parsons' and Abigail Housen's theories of aesthetic development, the study investigated whether or not four-year-olds are able to expand their initial responses to achieve deeper levels of understanding about works of art.

Three models are developed to analyze the state level conditions fostering the rise of far right parties in the European Union in the last two decades. The political background of these parties is examined. This study offers a definition for far right parties, which combines several previous attempts. The research has focused on the effects of the number of the parties, immigration, and unemployment on support for the far right in Europe. Empirical tests, using a random effects model of fifty elections in eight nations, suggest that there are political, social, and economic conditions that are conducive to electoral success. Specifically, increases in the number of "effective" parties favor the far right, while electoral thresholds serve to dampen support. Immigration proves to be a significant variable. Surprisingly, changes in crime and unemployment rates have a negative effect on support for the far right. Suggestions for future research are offered.

The primary purpose of this study was to determine the impact of a junior high school leadership program on the academic success and leadership development of its at-risk student participants. A secondary purpose, based on impact, was to evaluate the program as a potential school-based model for adolescent at-risk intervention. The leadership program investigated in this study is unique in three ways. First, the program is in a magnet school and the student population is heterogeneously mixed as to ethnicity and socio-economic status. Second, enrollment is open to all students. Third, its curriculum goals meet research-based criteria for effective intervention practices and leadership development. Academic success indicators associated with at-risk students included achievement, conduct, attendance, and school engagement. Leadership development indicators included leadership practices students had experienced and leadership positions students had held. The design of this post hoc study was the comparison of two groups of high school students who qualified as "at-risk" during their junior high years. Data collection included district or campus reports for cumulative attendance rates, grade point averages, and conduct demerits, as well as student survey responses for school activities, leadership practices experienced, and leadership positions held. Results of multivariate and univariate inferential analyses show …

In the last thirty years, there has been a significant increase in the globalization process, or as other refer to it, the internationalization, free trade, or liberalization. This trend was reflected in the increasing number of newly formed international organization (economic and security) as well as in the increased membership in the already existing ones. The evidence of this trend has been particularly visible since the end of the Cold War, when the race of the Eastern European countries to enter international organizations has been as competitive as ever. Nonetheless, a number of countries, upon careful evaluation and consideration of membership, has opted out of the opportunity to enter such international agreements. The question that this paper addresses is how do countries decided whether to enter or not international organizations? In other words, what elements, processes, and motives lie behind the decision of countries to commit to a new membership? Most of the studies that have addressed this topic have done so from an international perspective as they addressed the politics between countries, as well as the costs and benefits in terms of power, sovereignty, and national income once in the organizations. This paper, on the other hand, approaches the …

Agent-based architecture explains the rationale and basis for developing agents that can interact with users through natural language query/answer patterns developed systematically using AIML (artificial intelligence mark-up language) scripts. This thesis research document also explains the architecture for VISTA (virtual interactive story-telling agents), which is used for interactive querying in educational and recreational purposes. Agents are very effective as conversational interfaces when used along side with graphical user interface (GUI) in applications and Web pages. This architecture platform can support multiple agents with or with out sharing of knowledgebase. They are very useful as chat robots for recreational purposes, customer service and educational purposes. This platform is powered by Java servlet implementation of Program D and contained in Apache Tomcat server. The AIML scripting language defined here in is a generic form of XML language and forms the knowledgebase of the bot. Animation is provided with Microsoft® Agent technology and text-to-speech support engine.

Scholars often address the process of enlargement as one-sided argument. This work provides a general theory of organizational expansion by including strategies and actions of both, applicant states and members of international organizations. It is argued that dependent on the domestic characteristics of states an organization strategically implement a set of conditions to avoid the application and admission of states, which are either not able to conform with the rules or not willing to pay the costs of membership. This process incorporates two stages. I test this theory by utilizing a Heckman-Probit-Selection Model, which accounts for this two-stage procedure. The results confirm that conditions are important to avoid costs in the process of expansion.

Due to the rapid growth of wireless networking, the fallible security issues of the 802.11 standard have come under close scrutiny. Nowadays most of the organizations are eager to setup wireless local area networks to reduce the hassles of limited mobility provided by conventional wired network. There are serious security issues that need to be sorted out before everyone is willing to transmit valuable corporate information on a wireless network. This report documents the inherent flaws in wired equivalent privacy protocol used by the 802.11 standard and the ensuing security breaches that can occur to a wireless network due to these flaws. The solutions suggested in this report might not actually make the 802.11 standard secure, but will surely help in the lead up to a secure wireless network standard.

Martha Gellhorn and Ernest Hemingway met in Key West in 1937, married in 1941, and divorced in 1945. Gellhorn's work exhibits a strong influence from Hemingway's work, including collaboration on her work during their marriage. I will discuss three of her six novels: WMP (1934), Liana (1944), and Point of No Return (1948). The areas of influence that I will rely on in many ways follow the stages Harold Bloom outlines in Anxiety of Influence. Gellhorn's work exposes a stage of influence that Bloom does not describe-which I term collaborative. By looking at Hemingway's influence in Gellhorn's writing the difference between traditional literary influence and collaborative influence can be compared and analyzed, revealing the footprints left in a work by a collaborating author as opposed to simply an influential one.

This paper includes a 62-page book of original poems, 19 pages of which are visual poetry, and a 29-page preface which discusses visual poetry.

The unusually large hyperfine structure splittings in the 23P state of the 3He isotope is measured using electro-optic techniques with high precision laser spectroscopy. Originally designed to probe the fine structure of the 4He atom, this experimental setup along with special modifications I implemented to resolve certain 3He related issues has made possible new high precision hyperfine structure measurements. Discussed are the details of the experimental setup and the modifications, including in depth information necessary to consider while performing these measurements. The results of these hyperfine structure measurements give an order of magnitude improvement in precision over the best previously reported values.

This study explored the extent to which graduate students enrolled in Higher Education courses were proficient at writing. While writing proficiency has been extensively studied in elementary students, high school students, and undergraduates, little attention has been paid to formally evaluating graduate student proficiency. Despite the relatively new idea of assessing graduate student writing, it is a concern for graduate faculty and a valid area for study. This study was based on a sample of graduate students enrolled in at least one course in Higher Education at public institutions of higher education in the United States. A total sample size of 97 students was obtained. Two instruments were administered to the participants: A General Information and Writing Experience Questionnaire (G-WEQ) and the SAT II: Writing Test, Part B. The G-WEQ was designed to capture demographic information about the participants, as well as allow participants to provide a self-assessment of writing and describe the writing experiences they are currently encountering in graduate school. To assess writing proficiency for the participants, the SAT II: Writing Test, Part B was used. The purpose of the test is to "measure [test takers'] ability to...recognize faults in usage and structure, and to use language with …

This research shows that the Japanese rice policy has affected the volume of exported and imported rice; moreover, multilateral and bilateral agreements have also affected Japanese rice policy. Japan's institution of subsidies and trade barriers has made its rice products too expensive for foreign trade and its domestic consumers. Since the WTO agreement has forced Japan to open its market gradually over six years, Japan may be unable to compete internationally because of its limited land, high labor costs, and the field utility fees.
