An 8-Step Program: Shaping and Fixed-Time Food Delivery Effects on Several Approximations and Undesired Responses in Goats.
This study investigated the effects of a shaping program for halter training across 8 steps in the program and 4 trial-terminating, or "undesirable," responses. Three La Mancha goats (Capra hircus) located at the Frank Buck Zoo in Gainesville, Texas were used for the study. A fixed-time 15 s (FT-15 s) was used during the baseline conditions, to examine the effects of response contingent and response-independent food deliveries, as well as to examine what preliminary steps might not necessarily have to be shaped. All 3 goats successfully learned to allow the halter to be placed on them and to lead on the halter, although 2 of the 3 goats required an additional task analysis for the fifth step to further break down that approximation. Several of the early steps selected by the researchers were not necessary to complete the program, as determined by the baseline condition.
Accessing Information on the World Wide Web: Predicting Usage Based on Involvement
Advice for Web designers often includes an admonition to use short, scannable, bullet-pointed text, reflecting the common belief that browsing the Web most often involves scanning rather than reading. Literature from several disciplines focuses on the myriad combinations of factors related to online reading but studies of the users' interests and motivations appear to offer a more promising avenue for understanding how users utilize information on Web pages. This study utilized the modified Personal Involvement Inventory (PII), a ten-item instrument used primarily in the marketing and advertising fields, to measure interest and motivation toward a topic presented on the Web. Two sites were constructed from Reader's Digest Association, Inc. online articles and a program written to track students' use of the site. Behavior was measured by the initial choice of short versus longer versions of the main page, the number of pages visited and the amount of time spent on the site. Data were gathered from students at a small, private university in the southwest part of the United States to answer six hypotheses which posited that subjects with higher involvement in a topic presented on the Web and a more positive attitude toward the Web would tend to select the longer text version, visit more pages, and spend more time on the site. While attitude toward the Web did not correlate significantly with any of the behavioral factors, the level of involvement was associated with the use of the sites in two of three hypotheses, but only partially in the manner hypothesized. Increased involvement with a Web topic did correlate with the choice of a longer, more detailed initial Web page, but was inversely related to the number of pages viewed so that the higher the involvement, the fewer pages visited. An additional indicator of usage, the average amount …
Acculturative Processes and Their Impact on Self-Reports of Psychological Distress in Mexican-American Adolescents
The current study examined the effects of acculturative processes on the self-report of behavioral problems in Hispanic children ages 11-14. Acculturation was measured by the Acculturation Rating Scale for Mexican Americans-II (ARSMA-II) (ã Sage Publications, Thousand Oaks, CA, www.sagepub.com) (Cuellar, Arnold, and Maldonado, 1995) and the self-report of behavioral symptoms was assessed using the Youth Self-Report (ã T.M. Achenbach, Burlington, VT, www.aseba.com) (Achenbach, 1991). It was hypothesized that while both the linear and orthogonal categories of acculturation would account for a significant proportion of the variance in behavior problems in this age group, the orthogonal model would account for a larger proportion of variance due to its multidimensional nature. As well, it was hypothesized that the experimental Marginalization scales of the ARSMA-II would be predictive of behavioral problems. Multivariate analysis of variance was used to test these hypotheses and results were non-significant for the linear, orthogonal, and marginalization categories. The effects of the ethnic/cultural homogeneity of the region from which the sample was drawn, the buffering of social support, and the developmental aspects of ethnic identity are discussed as factors which may have influenced the potential impact of acculturative stress on psychological and behavioral functioning.
An Approach to the Critical Evaluation of Settings of the Poetry of Walt Whitman: Lowell Liebermann's Symphony No. 2
Walt Whitman's poetry continues to inspire composers of choral music, and the growing collection of musical settings necessitates development of a standard evaluative tool. Critical evaluation of the musical settings of Whitman's work is difficult because the extensive body of verse is complex and of uneven quality, and lack of common text among compositions makes comparison problematical. The diversity of musical styles involved further complicates the issue. Previous studies have focused on either ideology or style, but none have united the two critical approaches, thus restricting potential for deeper understanding of the music. This study proposes an approach to critical evaluation of Whitman settings that applies hermeneutics, or a blend of analysis and criticism, to the process. The hermeneutic approach includes an examination of the interrelationship between musical form and style and the composer's ideology, which is revealed through his/her treatment of Whitman's poetry and analyzed in light of cultural influences. Lowell Liebermann (b. 1961) has composed a large scale choral/orchestral setting of Whitman texts in his Symphony No. 2, opus 67 (1999). The selection, placement, and treatment of poetry in Symphony No. 2 provide a window into the composer's mind and his place in the current musical climate. Liebermann's setting reveals his interest in Whitman's search for spirituality and the human spirit's transcendence over time and space. His understanding of Whitman is filtered through a postmodern cynicism, which he seeks to remedy with his nostalgic neo-Romantic style. Chapter One provides an introduction to Whitman's life and examination of his poetry's themes, style, and reception. Chapter Two outlines issues relevant to criticism of Whitman settings and proposes an approach to critical analysis. Chapter Three applies the critical method to Liebermann's Second Symphony, drawing conclusions about its place in contemporary culture.
The Benefits of Adult Piano Study as Self-Reported by Selected Adult Piano Students.
The purpose of this study was to assess the benefits that selected adult piano students reported receiving from their study. Adult piano students (N = 711) from 24 states representing all geographic regions of the U.S. each completed a questionnaire containing 31 individual benefit items. These benefits were organized into 3 categories: Personal, Skill, and Social/Cultural. The demographic characteristics of the study population were consistent with the findings of other adult music research. Students indicated the existence (yes or no) of each benefit and rated the importance of existing benefits on a scale of 1-10. The category of Skill Benefits was the most agreed upon and highest rated category in the study, with over 90% agreement for each of the 7 Skill Benefits. The 14 Personal Benefits were also rated highly, particularly benefits related to self-actualization and fun. Self-related Personal Benefits were rated moderately, while more introverted Personal Benefits such as Imagination/Creativity, Spirituality, and Aesthetic Appreciation were lower rated benefits. The 10 Social/Cultural benefits were the lowest rated and least important benefits in the study. The most agreed upon benefits were Skill Improvement, Musical Knowledge, Musicianship, Accomplishment, Skill Refinement, Technique, Play/Fun, Escape from Routine, and Music Listening. The highest rated benefits in terms of importance were Dream Fulfilled, Technique, Accomplishment, Escape from Routine, Skill Improvement, Musicianship, Musical Knowledge, Play/Fun, Skill Refinement, and Personal Growth.
Candidates' Perception of Training and Self-Efficacy in Traditional and Alternative Teacher Preparation Programs.
This research was encouraged by the tremendous demand for teachers. Two million new teachers will be needed in the United States over the next decade. The teacher shortage has school administration, school boards, education agencies, and institutions of higher education investigating how to train and retain more teachers. Alternative certification programs have been developed to address the teacher shortage. This study examined the effectiveness of traditionally and alternatively certified teachers in two separate programs with regard to their self-efficacy, perception of their training, and their ExCET scores. Traditional candidates (10) and alternative candidates (74) were examined using survey research. According to this data on self-efficacy, perception of training, and ExCET passing rates, there is no significant difference between those teachers who receive traditional training and those who are trained in alternative certification programs.
A Case Study of Characteristics and Means of Person-to-Person Influence in American Kodály Music Education: Katinka Scipiades Dániel
The purpose of this study was to investigate the characteristics and means of Katinka Dániel's interpersonal influences through the perceptions of 20 selected students, protégés, and colleagues, and to study the behavioral and attitudinal changes they attributed to her influence. A case study design and structured interview questionnaire were used to study four variables coming from the social sciences' literature on influence: legitimate authority, attractiveness, expert authority, and trustworthiness. Responses were qualitatively analyzed to determine the role those variables played in Dániel's interpersonal influence. All interviewees were music teachers who used the Kodály method in their teaching and have studied or worked with Dániel. Two images of Dániel emerged from the interviews. The first, a business-like image, emanated from Dániel's work in the classroom, and the second, a maternal image, came from personal relationships with her students and associates. Attractiveness (defined as a willingness to respond positively to the requests of an influential person because one respects that individual and wants to obtain that person's approval) proved to be the principal characteristic of influence, followed by legitimate authority, then expertise. Trustworthiness played a lesser role. The greatest effect of Dániel's influence was on the interviewees' teaching. Among the factors interviewees described as influential were her expectation they would succeed, her position as role model, praise and encouragement, and gestures of generosity and concern. Interviewees were not in agreement as to whether she used persuasion or coercion. Direct verbal communication served a principal role in Dániel's influence, and though her criticism was described as forthright and bluntly honest, interviewees often accepted it. This was because most believed she was focused on their best interest, because her motives were not considered self-serving, and because they saw the reasons for her criticism as stemming from her high ideals and the desire to see …
Characterization of Iron Oxide Deposits Formed at Comanche Peak Steam Electric Station
The presence of deposits leading to corrosion of the steam generator (SG) systems is a major contributor to operation and maintenance cost of pressurized water reactor (PWR) plants. Formation and transport of corrosion products formed due to the presence of impurities, metallic oxides and cations in the secondary side of the SG units result in formation of deposits. This research deals with the characterization of deposit samples collected from the two SG units (unit 1 and unit 2) at Comanche Peak Steam Electric Station (CPSES). X-ray diffraction (XRD), Fourier transform infrared spectrophotometry (FTIR), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) techniques have been used for studying the compositional and structural properties of iron oxides formed in the secondary side of unit 1 and unit 2. Magnetite (Fe3O4) was found to be predominant in samples from unit 1 and maghemite (g-Fe2O3) was found to be the dominant phase in case of unit 2. An attempt has been made to customize FTIR technique for analyzing different iron oxide phases present in the deposits of PWR-SG systems.
Coaching Behavior Preferences of Interscholastic Athletes
The purpose of this study was to determine whether coaching behavior preferences of interscholastic athletes differ as a function of gender and type of sport. The Coaching Behavior Questionnaire (CBQ; Martin & Barnes, 1999) was administered to 372 interscholastic athletes. The mean scores of the participants' responses to each subscale on the CBQ were the dependent variables and gender and type of sport were the independent variables. Descriptive statistics revealed that female and male interscholastic athletes who perform on coactive, mixed, and interactive sport teams preferred coaches who engage in supportive and instructional behaviors, as opposed to non-responses or negative responses. A 2 (Gender) X 3 (Type of Sport) MANOVA and discriminant function analyses indicated that gender and the degree of interdependency between group members affects preferred coaching behavior. Thus, coaches should consider situational factors and personal characteristics when working with interscholastic athletes.
Comparative Analysis of Management and Employee Job Satisfaction and Policy Perceptions.
The purpose of the study was to investigate the perceptions of job satisfaction as defined by management and nonmanagement employees and to compare both parties' perceptions of organizational benefits to a list prepared by the organization's benefit personnel. Turnover is costly to the organization, both in money and in the impact it has on those individuals remaining with the organization. Every effort should be undertaken to reduce the amount of turnover within the organization. A contributing factor leading to turnover may be a gap between what the employees believe is important to them and what management believes is important to the employees. The boundaries of the gap need to be identified before any effort can be made to reduce or bridge the gap. Once the boundaries are identified, policies can be analyzed and the possibility of reducing the gap investigated. Management as a whole must be aware of the needs and wants of their employees before any attempt to develop a retention strategy is undertaken. This knowledge can be acquired only through two-way communication with the employee. The communication process includes the simple process of asking employees for this information and then listening to how they respond. This study suggests that little difference exists in perception of job satisfaction importance for gender, age group, length of time with the organization, topic training hours, and between management and nonmanagement employees. However, perception gaps exist between the job satisfaction items addressed by organizational policies and procedures and those perceived by employees. Additional studies that include a number of varied organizations are needed before extensive generalizations can be made.
A Comparison of Skill Level of Parents Trained in the Landreth Filial Therapy Model and Graduate Students Trained in Play Therapy
The purpose of this study was to determine if parents trained in the Landreth Filial Therapy Model could demonstrate child-centered play therapy skills as effectively as graduate play therapy students who completed an Introduction to Play Therapy course. The participants in both the parent group and the graduate student group were videotaped in play sessions with children pre- and post-training in order to measure change in adult empathic behavior as defined on the Measurement of Empathy in Adult-Child Interaction (MEACI). The specific skills measured in this study were (a) communicating acceptance to the child, (b) allowing the child to direct his or her own play during the play sessions, (c) demonstrating appropriate levels of involvement in the child's play, and (d) demonstrating empathic behavior toward the child. The Landreth Filial Therapy Model is a training system that utilizes both didactic and dynamic means to train parents and other paraprofessionals to be therapeutic agents of change with children. Parents are taught child-centered play therapy skills to use in weekly home play sessions with their children in order to strengthen the emotional bond between parent and child. The Introduction to Play Therapy course is a graduate-level counseling course at the University of North Texas taught by Dr. Garry Landreth. The course focuses on the philosophy, theory, and skills of child-centered play therapy. Students enrolled in this course typically plan to use play therapy in professional settings. The filial-trained parent group (n = 21) consisted of the experimental group of single parents from Bratton and Landreth's (1995) study, Filial Therapy with Single Parents, Effects of Parental Acceptance, Empathy and Stress. The parents met for weekly 2-hour filial therapy sessions over the course of 10 weeks and conducted six or seven 30-minute play sessions at home with their child-of-focus. The graduate student group (n …
Comparisons of Improvement-Over-Chance Effect Sizes for Two Groups Under Variance Heterogeneity and Prior Probabilities
The distributional properties of improvement-over-chance, I, effect sizes derived from linear and quadratic predictive discriminant analysis (PDA) and from logistic regression analysis (LRA) for the two-group univariate classification were examined. Data were generated under varying levels of four data conditions: population separation, variance pattern, sample size, and prior probabilities. None of the indices provided acceptable estimates of effect for all the conditions examined. There were only a small number of conditions under which both accuracy and precision were acceptable. The results indicate that the decision of which method to choose is primarily determined by variance pattern and prior probabilities. Under variance homogeneity, any of the methods may be recommended. However, LRA is recommended when priors are equal or extreme and linear PDA is recommended when priors are moderate. Under variance heterogeneity, selecting a recommended method is more complex. In many cases, more than one method could be used appropriately.
Complexity as a Form of Transition From Dynamics to Thermodynamics: Application to Sociological and Biological Processes.
This dissertation addresses the delicate problem of establishing the statistical mechanical foundation of complex processes. These processes are characterized by a delicate balance of randomness and order, and a correct paradigm for them seems to be the concept of sporadic randomness. First of all, we have studied if it is possible to establish a foundation of these processes on the basis of a generalized version of thermodynamics, of non-extensive nature. A detailed account of this attempt is reported in Ignaccolo and Grigolini (2001), which shows that this approach leads to inconsistencies. It is shown that there is no need to generalize the Kolmogorov-Sinai entropy by means of a non-extensive indicator, and that the anomaly of these processes does not rest on their non-extensive nature, but rather in the fact that the process of transition from dynamics to thermodynamics, this being still extensive, occurs in an exceptionally extended time scale. Even, when the invariant distribution exists, the time necessary to reach the thermodynamic scaling regime is infinite. In the case where no invariant distribution exists, the complex system lives forever in a condition intermediate between dynamics and thermodynamics. This discovery has made it possible to create a new method of analysis of non-stationary time series which is currently applied to problems of sociological and physiological interest.
The Concept of Dignity in the Early Science Fiction Novels of Kurt Vonnegut.
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.
Construct Validity of Psychopathy in Mentally Disordered Offenders: A Multi-trait Multi-method Approach
Psychopathy continues to receive increased attention due to the negative outcomes, including recidivism, violence, and poor treatment amenability. Despite the vast amount of attention psychopathy has received, research on its applications to mentally disordered offenders remains sparse. The current study explored the relationship between psychopathy, depression, anxiety, and psychotic disorders. It also investigated the comparative fits of two and three-factor models of the PCL-R with mentally disordered offenders. Participants consisted of 96 inmates placed in the mental health pod at Tarrant County Jail. A Confirmatory Factor Analysis (CFA) with testlets found the three-factor PCL-R model had excellent fit (Robust Comparative Fit Index = 1.00). Psychopathy was found to be a construct independent of mental disorders. Two exceptions were (a) a modest correlation between anxiety and Impulsive and the Irresponsible Lifestyle factor of the PCL-R (r = 0.20) and (b) a modest negative correlation between Deficient Affective Experience of the PCL-R and mania (r = -.37). Based on the current data, treatment programs for mentally disordered offenders are suggested that focus on both behavioral and personality aspects of psychopathy.
The Czech Republic's Transition: The Environment and Human Rights
This exploratory case study considers the Czech Republic from 1993 thru 2002 by examining two links: first, between transition and the environment.; second, between the environment and human rights. The study examines data from the Czech Ministry of Environment, the European Union, the World Bank, and Freedom House. The purpose of this study is to better understand the Czech Republic and to generate hypotheses that might be used in future cross-national studies. Chapter III provides the underlying theory linking the environment and human rights. Chapters IV, V, and VI discuss the data and the two links and suggest hypotheses for future research. Chapter VII draws conclusions about states in transition, the environment, and human rights and encourages future integrative research.
Damned Good Daughter.
My dissertation is a memoir based on my childhood experiences growing up with a mentally ill mother. She exhibited violence both passive and aggressive, and the memoir explores my relationship with her and my relationship with the world through her. "Damned Good Daughter" developed with my interest in creative nonfiction as a genre. I came to it after studying poetry, discovering that creative nonfiction offers a form that accommodates both the lyric impulse in poetry and the shaping impulse of story in fiction. In addition, the genre makes a place for the first person I in relation to the order and meaning of a life story. Using reverse chronology, my story begins with the present and regresses toward childhood, revealing the way life experiences with a mentally ill parent build on one another.
A Descriptive Study of the Intelligence Community in the United States of America
This treatise represents a descriptive study of the intelligence community in the United States. It explores the ramifications of terrorism on the intelligence function, post September 11, 2001. In-depth discussions concerning the structure of the U.S. intelligence community are presented as well as a focus on the defined steps of the intelligence process: planning and directions, collection, analysis, production, and dissemination. The final aspect of this study poses questions and issues relating to the restructuring of the U.S. intelligence community in light of the Homeland Security Act of 2002.
Developmental Patterns of Metabolism and Hematology in the Late Stage Chicken Embryo (Gallus Domesticus) at Two Incubation Temperatures.
How temperature affects physiological development in the chicken embryo is unknown. Embryos incubated at 38°C or 35°C showed no difference in growth or survival. The time to hatching was longer in 35°C than 38°C embryos (23.7 vs. 20.6 days), but unaffected was the relative timing of appearance of developmental landmarks (internal, external pipping). At stage 43-44, 38°C embryos maintained oxygen consumption around 1 mL/g/h despite acute temperature reduction (suggesting thermoregulatory maturation), unlike 35°C embryos. In 35°C embryos the lower oxygen-carrying capacity and temperature insensitive blood O2 affinity (P50 about 30 mmHg) may restrict O2 delivery to tissues, limiting metabolism during decreased ambient temperature. Reduced incubation temperature retards normal hematological and thermoregulatory development.
Dimensional Assessment of Empowerment in Organizations
This research project was inspired by a survey that was designed to help an organization determine how well it was doing in its efforts to empower associates and achieve a goal of continuous improvement. Initial review of the survey created suspicion that the survey was not built around the appropriate dimensions to accurately measure the level of empowerment in organizations. As such, the survey was psychometrically analyzed to determine the validity of the instrument as a measure of empowerment. Additionally, an extensive review of the literature was performed to determine new dimensions that would most accurately measure empowerment. Eight dimensions (culture, trust, accountability, leadership, ability, commitment, responsibility, and communication) were put forth as the most appropriate to measure empowerment. Subject matter experts with knowledge and experience in the area of organizational empowerment reviewed the new dimensions for accuracy and fit with the original survey items.

The Domestic Politics of Entering International Communities: An Exploratory Analysis
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 issue from a comparative perspective, both economic and political. It attempts to answer the research question by looking at the domestic sources of decision -making and how they influence this decision. Namely, a decision to become more open to trade has several implications for a country, depending on its size, and already established trade openness, among other factors. The impact of increased openness will most seriously affect the domestic players, both negatively and positively. Thus, in considering the impact that the policy could have on their welfare, players align their interests in order to express their preferences on the issue …
The Dynamic Foundation of Fractal Operators.
The fractal operators discussed in this dissertation are introduced in the form originally proposed in an earlier book of the candidate, which proves to be very convenient for physicists, due to its heuristic and intuitive nature. This dissertation proves that these fractal operators are the most convenient tools to address a number of problems in condensed matter, in accordance with the point of view of many other authors, and with the earlier book of the candidate. The microscopic foundation of the fractal calculus on the basis of either classical or quantum mechanics is still unknown, and the second part of this dissertation aims at this important task. This dissertation proves that the adoption of a master equation approach, and so of probabilistic as well as dynamical argument yields a satisfactory solution of the problem, as shown in a work by the candidate already published. At the same time, this dissertation shows that the foundation of Levy statistics is compatible with ordinary statistical mechanics and thermodynamics. The problem of the connection with the Kolmogorov-Sinai entropy is a delicate problem that, however, can be successfully solved. The derivation from a microscopic Liouville-like approach based on densities, however, is shown to be impossible. This dissertation, in fact, establishes the existence of a striking conflict between densities and trajectories. The third part of this dissertation is devoted to establishing the consequences of the conflict between trajectories and densities in quantum mechanics, and triggers a search for the experimental assessment of spontaneous wave-function collapses. The research work of this dissertation has been the object of several papers and two books.
The Effect of a Laboratory-based, In-context, Constructivist Teaching Approach on Preservice Teachers' Science Knowledge and Teaching Efficacy.
This study began with a concern about elementary teachers, as a whole, avoiding the teaching of science in the elementary classroom. The three main factors noted as reasons for this avoidance were: (1) minimum science requirements to reach certification, leading to a lack of preparedness; (2) lack of exposure to science in elementary school; and (3) general dislike for and understanding of science leading to a low self-efficacy in science teaching. The goal of the Environmental Science Lab for Elementary Educators (ESLEE) was to conduct an intervention. The intervention was lab-based and utilized in-context, constructivist approaches to positively influence participants' abilities to retain science content knowledge and to affect their belief in themselves as teachers. This intervention was created to respond to all three of the main avoidance factors noted above. The research utilized a quasi-experimental, pretest-posttest control group design. Two pretests and two posttests (science teaching efficacy and content knowledge) were given to all 1,100 environmental science lab students at the participating institution over two long semesters. Three experimental/control groups were formed from this population. The Experimental Group was comprised of 46 students who participated in the ESLEE Intervention. Control Group 1 was comprised of 232 self-described preservice educators (SDPEEs) in "regular" labs. Control Group 2 was comprised of 62 nonSDPEEs taught by ESLEE instructors in "regular" lab settings. A DM MANOVA was used to analyze the data. The results demonstrated that the ESLEE Intervention was statistically significant at the p> .05 level for science teaching efficacy between the Experimental Group and Control Group 1, and was statistically significant for both content knowledge and efficacy between the Experimental Group and Control Group 2. More notably, the effect size (delta) results ranged from .19 to .71 and .06 to .55 (partial eta squared) and demonstrated the practical significance of implementing …
The Effects of Alternative Contingencies on Instruction Following.
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 Effects of an Oral History Interview on Counselor Trainees' Confidence and Couples' Intimacy
A major concern many counselor trainees face when preparing to see their first couple-client is that of confidence because they have had little to no experience in interacting in a professional capacity with couples. Many beginning counselors experience anxiety, which can inhibit their effectiveness with clients (Scanlon & Baille, 1994). Introducing counselor trainees to a relatively non-threatening interaction with couples might reduce the initial anxiety that characterizes the neophyte counselor venturing into new clinical territory. The interaction may also enhance feelings of warmth and closeness of the couples. John Gottman's Oral History Interview (Gottman, 1999) was the protocol used in the interaction between trainee and couple. An instrument developed for this study to measure couple counseling confidence, the State Trait Anxiety Inventory (Spielberger, 1983), and the Personal Assessment of Intimacy in Relationships (Schaefer & Olson, 1981) were used to assess levels of counselor confidence, counselor anxiety, and couple intimacy, respectively. The confidence instrument and State-Trait Anxiety Inventory were administered to 37 students who were enrolled in four graduate level introductory couple counseling classes and who interviewed couples, as well as to 34 counselor-trainees who were enrolled in five graduate level counseling courses other than couple counseling and who did not interview couples. Analyses of the quantitative data revealed no statistically significant differences in confidence between trainees who interviewed a couple and trainees who did not interview a couple. Analyses of qualitative data suggested there were differences. The Personal Assessment of Intimacy in Relationships was administered to 67 individual couple participants who were interviewed by counselor trainees, and 35 individual couple participants who were not interviewed by counselor-trainees. Analyses of the quantitative data revealed no statistically significant differences in couples who participated in the Oral History Interview and those who did not. Analyses of qualitative data suggested there were differences. Regarding …
The Effects of Biofeedback and Verbal Feedback on the Training and Maintenance of Diaphragmatic Breathing
The purpose of this study was to evaluate the effects of a computer program on the training and maintenance of diaphragmatic breathing. The biofeedback portion was visual computer training and the results were displayed concurrently with participants' breathing responses to monitor display. The verbal feedback portion was praise that was given and recorded when participants responded with predominantly diaphragmatic breathing at the scheduled moment and response instruction that was given when participants responded with predominantly thoracic breathing. The results of this study indicate the computer program's effectiveness needs to be increased by supplementation with verbal feedback.
The Effects of Monitoring and Incompatible Contingencies on Say/Do Correspondence.
This study investigated effects of monitoring on correspondence between nonverbal responding and verbal descriptions of those contingencies, when verbal descriptions and contingencies were compatible and when incompatible. In the Nonverbal Component, the contingency for key pressing was either on a 0.8 s IRT or a 3.4 s IRT. In the Verbal Component, subjects made responses to a statement about the contingency for reinforcement in the Nonverbal Component. Shaping was used to establish targets of 0.8 s and 3.4 s in this component. Results indicated that across 7/8 opportunities subjects exhibited nonverbal and verbal behavior that was sensitive to their respective contingencies regardless of compatibility. This sensitivity to contingencies was not affected by the presence of a monitor.
The Effects of Practice Procedure and Task Difficulty on Tonal Pattern Accuracy.
The study investigated the relative effectiveness of different proportions of time spent on physical and mental practice, in the context of a music performance of a tonal pattern over harmonic progressions of two difficulty levels. Using a sampling without replacement procedure, sixty undergraduate students were assigned to four practice groups partially blocked for musical instrument. The groups included a physical practice group, a mental practice group and two combined mental and physical practice groups in the proportions of (a) 66% physical and 33% mental, and (b) 33% physical and 66% mental. Each subject performed a pretest, a 3 minute practice session, and a posttest on both harmonic progressions. Presentation of the harmonic progressions were counterbalanced to control for practice effects All pre- and posttests were recorded and scored according to number of note errors. An ANCOVA procedure using pretest scores as covariates revealed that: (a) there were no differences between the different practice groups on the measure of note errors, (b) there was a significant difference between the two harmonic progressions on the measure of note errors, such that performance on the easy progression was significantly better than performance on the hard progression, and (c) there was a significant interaction between harmonic difficulty level and the practice groups. Post hoc comparisons between the adjusted means of the practice groups on the two tasks revealed that for the mental and the 33:66 combined practice groups, groups consisting of a higher percentage of mental practice, performance on the easy harmonic progression was significantly better than on the hard harmonic progression. However for the physical and the 66:33 combined practice groups, groups consisting of a higher percentage of physical practice, performance on both harmonic progressions was not significantly different and was as good as the performance of all practice groups on the easy …
The Effects of Response Restriction on Non-Socially Maintained Self-Injury
This study examined the effects of response restriction (blocking and protective equipment) on subsequent durations of self-injury with two female participants with developmental disabilities. First, a functional analysis was conducted with each participant to identify potential maintaining variables of the self-injury. Second, access to the response was systematically restricted in a multiple schedule restriction paradigm. A baseline extended alone was conducted without the restriction component in place as a control condition. For one participant the results suggested that response restriction may have increased subsequent durations of responding once the restriction element was removed. For a second participant responding did not appear to be affected by the restriction component.
Effects of Web-based Instruction in High School Chemistry.
The intent of this study is to identify correlations that might exist between Web-based instruction and higher assessment scores in secondary education. The study framework was held within the confines of a public high school chemistry classroom. Within this population there were students identified as gifted and talented (GT) as well as those without this designation. These two classifications were examined for statistically higher assessment scores using a two-tailed t-test. Results indicated that females outperformed males on pre- and post- instructional unit tests. All subgroups improved their logical-thinking skills and exhibited positive attitudes towards Web-based instruction. In general, Web-based instruction proved beneficial to improving classroom performance of all GT and non-GT groups as compared to traditional classroom instruction.
Elementary Teacher Attrition and Factors of Organizational Climate
As the United States faces a critical teacher shortage, it is important to examine all factors that may contribute to the revolving door of teacher attrition. This study explored the climate of elementary schools to determine if there was a correlation between teacher attrition and school organizational climate. Three basic research questions were addressed: 1) Is there a relationship between school organizational climate and teacher attrition? 2) Is a change in campus leadership related to school organizational climate? 3) Is there a relationship between a change in campus leadership and teacher attrition? Thirty-seven elementary schools were examined in terms of their individual teacher attrition rates and their climate survey scores. The data utilized in this study came from one school district's climate survey and teacher attrition rates for the 2000-2001 school year. The findings of this study indicate that factors of organizational climate may predict teacher attrition rates. Specifically, instructiona support may be related to teacher attrition. Major components of instructional support include principal behaviors, respect for teaching and learning, and communication with administrators. Teacher attrition was not related to principal experience. Also, principal experience was not related to factors of school organizational climate.
An Empirical Investigation of Critical Factors that Influence Data Warehouse Implementation Success in Higher Educational Institutions
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. Also, that some variables in the post-implementation phase have a significant relationship with performance. Based on the results of the tests the model was revised to reflect the relative impact of technical and organizational factors on DW performance. Results suggest that in some cases organizational factors have a significant relationship with DW implementation performance. The implications and interpretation of these results provide researchers and practitioners' insights and a new perspective in the area of DW implementations.
Explorations with optically active, cage-annulated crown ethers.
A variety of optically active macrocyclic crown ethers that serve as "host" systems that are capable of differentiating between enantiomeric "guest" molecules during host-guest complexation have been prepared via incorporation of chiral elements into the crown ring skeleton. The ability of these crown ethers to recognize the enantiomers of guest salts, i.e., (+) a-methyl benzylamine and to transport them enantioselectively in W-tube transport experiments were studied. The ability of these crown ethers to perform as chiral catalysts in an enantioselective Michael addition was studied. The extent of asymmetric induction, expressed in terms of the enantiomeric excess (%ee), was monitored by measuring the optical rotation of the product and comparing to the literature value.
Extreme Politics: An Analysis of the State Level Conditions Favoring Far Right Parties in the European Union
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.
Faculty Attitudes Toward Residential and Distance Learning: A Case Study in Instructional Mode Preferences Among Theological Seminary Faculty
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 are to provide an overall norm-referenced, predictive score estimating the organization's likelihood of adopting and implementing an innovation and to profile the strengths and weaknesses of an organization's environment (culture) relative to the adoption and implementation of innovations. Five scales provide a comprehensive understanding of the organizational climate, personality and leadership characteristics of participants, communication pathways within the organization, the degree of sophistication or expertise within the organization, and the receptivity of the students. An official administration of the instrument was conducted involving all full-time faculty at DTS. Frequency counts, percentage distributions, and the chi-square goodness-of-fit statistic were used to …
Financial Transfer and Its Impact on the Level of Democracy: A Pooled Cross-Sectional Time Series Model.
This dissertation is a pooled time series, cross-sectional, quantitative study of the impact of international financial transfer on the level of democracy. The study covers 174 developed and developing countries from 1976 through 1994. Through evaluating the democracy and democratization literature and other studies, the dissertation develops a theory and testable hypotheses about the impact of the international variables foreign aid and foreign direct investment on levels of democracy. This study sought to determine whether these two financial variables promote or nurture democracy and if so, how? A pooled time-series cross-sectional model is developed employing these two variables along with other relevant control variables. Control variables included the presence of the Cold War and existence of formal alliance with the United States, which account for the strategic dimension that might affect the financial transfer - level of democracy linkage. The model also includes an economic development variable (per capita Gross National Product) to account for the powerful impact for economic development on the level of democracy, as well as a control for each country's population size. By addressing and the inclusion of financial, economic, strategic, and population size effects, I consider whether change in these variables affect the level of democracy and in which direction. The dissertation tests this model by employing several techniques. The variables are subjected to bivariate and multivariate analysis including bivariate correlations, analysis of variance, and ordinary least square (OLS) multivariate regression with robust matrix and a lagged dependent variable. Panel corrected standard error (PCSE) was also employed to empirically test the pooled timeseries cross-sectional multivariate model. The dissertation analytical section concludes with path analysis testing which showed the impact of each of the independent variables on the dependent variable. The findings indicate less impact of international financial variables upon the level of democracy than hypothesized. …
"For Reformation and Uniformity": George Gillespie (1613-1648) and the Scottish Covenanter Revolution
As one of the most remarkable of the Scottish Covenanters, George Gillespie had a reputation in England and Scotland as an orthodox Puritan theologian and apologist for Scottish Presbyterianism. He was well known for his controversial works attacking the ceremonies of the Church of England, defending Presbyterianism, opposing religious toleration, and combating Erastianism. He is best remembered as one of the Scottish Commissioners to the Westminster Assembly in London, which sought to reform the English Church and establish a uniform religion for the two kingdoms. This study assesses his life, ideas, and legacy. In Gillespie's estimation revelation and reason played complementary roles in the Christian life. While the Fall had affected man's reasoning abilities, man could rely upon natural law and scholarship as long as one kept them within the limits of God's truth revealed in Scripture. Moreover, he insisted that the church structure its worship ceremonies, government, and discipline according to the pattern set forth in the Bible. In addition, he emphasized the central role of God's Word and the sacraments in the worship of God and stressed the importance of cultivating personal piety. At the heart of Gillespie's political thought lay the Melvillian theory of the two kingdoms, which led him to reject Erastianism as subordinating the church to the power of the state. Furthermore, his delineation of the limits of the authority of the civil magistrate, presented a challenge to the state's authority and led him to formulate a radical version of the Covenanter doctrine of resistance to the state. While Gillespie supported uniformity of religion between England and Scotland, opposed religious toleration, and rejected the Engagement with King Charles, none of these causes proved successful in his lifetime. Yet these ideas influenced generations of Resolutioners, Protestors, Cameronians, and other heirs of the Scottish Covenanter tradition.
The Great Debate continued: Does daily writing in kindergarten lead to invented spelling and reading?
Many children in the United States cannot read on level by fourth grade. Traditionally, teachers have delayed reading instruction until first grade. However, involving children sooner in literary activities may provide skills needed to enable them to read on grade level. The purpose for this study was to determine the extent to which daily writing in kindergarten influences the development of invented spelling and learning to read. Five teachers modeled writing with 78 kindergarten children who wrote every day or almost every day for 20 weeks. There were 51 children in an experimental group, and 27 in a control group who were given a pretest and a posttest using the Observation Study (Clay, 1993). Results from a mixed model ANOVA indicated a significant difference between the control group and the experimental group on the Dictation Task F (1, 76) = 11.76, P≤ .001 and the Writing Test F (1, 76) = 4.33, P≤ .01. Results from a z-Test of dependent proportions indicated there were significant differences in the reading levels of the control group from the pretest to the posttest (z = 7.51, P ≥ .05) because (z = 7.51, Zcv = 1.96). The experimental group results from pretest to posttest were also statistically significant (z = 6.48, P ≥ .05) because (z = 6.48, Zcv = 1.96). At the end of kindergarten 82.35% of the experimental group was reading, while only 48.15% of the control group was reading. This research indicates that if kindergarten children are encouraged to write daily and use invented spelling there is a greater possibility they will enter first grade reading.
Ignacy Jan Paderewski's Sonata in E-Flat Minor, Op. 21: Insights into his compositional technique and performance style.
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 performance style documented in recordings of his own compositions and of works by Chopin, Schumann, Liszt, and Beethoven. Consideration is given to various aspects of interpretation, including counterpoint, asynchrony, tempo rubato, rhythmic variance, and pedaling. Each of these aspects of Paderewski's performance style is illustrated with transcriptions of excerpts from Paderewski's recordings. The author proposes examples of application of these aspects to Paderewski's Sonata, Op. 21. Chapter 5 provides a summary of the project. Appendix A contains an analysis of the rhythmic grouping that performers may find useful, and Appendix B contains the recital programs required for the degree program.
The impact of a junior high school leadership program on the academic success and leadership development of at-risk students.
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 the leadership program had a slight positive impact on the achievement and leadership experiences of at-risk student participants. Descriptive data analyses indicated a positive trend toward better conduct from program participants as well. The program did not have a significant impact on attendance, school engagement, and leadership positions students had held. While the program met criteria for effective at-risk intervention as well as exemplary leadership development, results were mixed, so evaluation of the leadership program as a model for at-risk student intervention is inconclusive. Further longitudinal research is recommended with a larger sample, using pretest and posttest measurements, group comparisons, …
Increasing the Dynamic Range of Audio THD Measurements Using a Novel Noise and Distortion Canceling Methodology
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.
Interfacial Electrochemistry of Metal Nanoparticles Formation on Diamond and Copper Electroplating on Ruthenium Surface
An extremely facile and novel method called spontaneous deposition, to deposit noble metal nanoparticles on a most stable form of carbon (C) i.e. diamond is presented. Nanometer sized particles of such metals as platinum (Pt), palladium (Pd), gold (Au), copper (Cu) and silver (Ag) could be deposited on boron-doped (B-doped) polycrystalline diamond films grown on silicon (Si) substrates, by simply immersing the diamond/Si sample in hydrofluoric acid (HF) solution containing ions of the corresponding metal. The electrons for the reduction of metal ions came from the Si back substrate. The diamond/Si interfacial ohmic contact was of paramount importance to the observation of the spontaneous deposition process. The metal/diamond (M/C) surfaces were investigated using Raman spectroscopy, scanning electron microscopy (SEM), x-ray photoelectron spectroscopy (XPS) and x-ray diffractometry (XRD). The morphology (i.e. size and distribution) of metal nanoparticles deposits could be controlled by adjusting the metal ion concentration, HF concentration and deposition time. XRD data indicate the presence of textured and strained crystal lattices of Pd for different Pd/C morphologies, which seem to influence the electrocatalytic oxidation of formaldehyde (HCHO). The sensitivity of electrocatalytic reactions to surface crystal structure implies that M/C could be fabricated for specific electrocatalytic applications. The research also presents electroplating of Cu on ruthenium (Ru), which a priori is a promising barrier material for Cu interconnects in the sub 0.13 μm generation integrated circuits (ICs). Cu plates on Ru with over 90% efficiency. The electrochemical nucleation and growth studies using the potentiostatic current transient method showed a predominantly progressive nucleation of Cu on Ru. This was also supported by SEM imaging, which showed that continuous thin films of Cu (ca. 400 Å) with excellent conformity could be plated over Ru without dendrite formation. Scotch tape peel tests and SEM on Cu/Ru samples both at room temperature (RT) and …
An Investigation into the Effects of Long-term Staff Development on Teacher Perceptions and Reading Achievement on Young Children
The effectiveness of long-term staff development (Reading Academy Project-RAP) on students' reading scores on the Texas Assessment of Academic Skills (TAAS) test was examined to determine if teachers transferred newly learned teaching strategies into practice and changed their beliefs about reading instruction. In a four-year cohort longitudinal study in an East Texas rural community, the effects of long-term staff development on third grade students' TAAS test reading scores, teacher practices, and teacher beliefs were explored. Populations included a teacher group (N = 17), an experimental (N = 419), and a control (N = 419) group of students. Children's groups were matched pairs based on five demographic characteristics and membership or non-membership in one or more of six categories. An application survey and four end-of-the-year surveys provided teacher data regarding classroom practices. One interview question provided information about teacher beliefs. Results indicate students who had a RAP teacher for at least one year scored significantly higher on the TAAS reading test in the third grade than those without a RAP teacher. Examination of students having more than one year with an academy teacher failed to produce statistically significant differences in TAAS test reading scores; however, an upward trend was noted. Statistically significant differences were found in 6 of the 20 items on the survey investigating classroom practices. All teachers reported the RAP affected them positively, and 82% confirmed that changes took place in their classroom practices, student behaviors, and teacher responsibilities. Validation of or strengthening existing beliefs accounted for 76% of the teacher responses. Recommendations include adding a population of kindergarten through third graders and following them through high school to determine ultimate reading success, continue surveying teachers to see if effective strategies persist, add a parental involvement component, and replicate this investigation in suburban and metropolitan areas.
Investigation of Pyrimidine Salvage Pathways to Categorize Indigenous Soil Bacteria of Agricultural and Medical Importance and Analysis of the Pyrimidine Biosynthetic Pathway's Enzyme Properties for Correlating Cell Morphology to Function in All Phases of Growth
This dissertation comprises three parts and is presented in two chapters. Chapter 1 concerns Arthrobacter, a bacterium with an intriguing growth cycle. Whereas most bacteria exist as either a rod or coccus, this bacterium shares the rod/coccus lifestyle. It therefore seemed important to examine the growth regulatory pathways from the rod and coccus. The committed step, that catalyzed by aspartate transcarbamoylase (ATCase), in the pyrimidine biosynthetic pathway was chosen. The ATCase in Arthrobacter is like the well known Pseudomonas enzyme except that it has an active dihydroorotase (DHOase) associated. Included in Chapter 1 is the description of a microorganism, Burkholderia cepacia, whose ATCase has characteristics that are at once reminiscent of bacteria, mammals, and fungi. It differs in size or aggregation based on environmental conditions. In addition, it has an active DHOase associated with the ATCase, like Arthrobacter. B. cepacia is important both medically and for bioremediation. Since B. cepacia is resistant to most antibiotics, its unique ATCase is a prime target for inhibition. Whereas the first chapter deals with the de novo pathway to making pyrimidines, which is found mainly in the lag and log phase, Chapter 2 addresses the salvage pathway, which comes more into play during the stationary phase. This section focuses on the isolation, identification, and grouping of a number of natural soil bacteria from various soil locations. These organisms are important agriculturally, medically, and industrially. Addition of these soil isolates to poor soils has been found to improve the soil. In a previous study by D.A. Beck, the salvage schemes for a number of laboratory strains of microorganisms were determined. Nine separate classes of salvage were designated by determining the salvage enzymes present. In this study emphasis has been placed on soil bacteria, which had not previously been analyzed. A number of species of soil …
Jean-Georges Kastner's Traité general d'instrumentation: A Translation and Commentary
Georges Kastner's (b Strasbourg 9 March 1810; d Paris 19 December 1867) Traite général d'instrumentation (1837), an important contribution to instrumentation study, is often overlooked because of its chronological proximity to Berlioz's Grand traité d'instrumentation (1843). Kastner's complete and concise treatise discusses the standard orchestral instruments and several obscure and ancient instruments. Intended principally for young composers, it provides the most detailed descriptions of the standard wind instruments of his day and discusses recent developments like the ophicleide and valved brass instruments. After the publication of the Traité, Kastner released a supplement including Aldophe Sax's newest innovations, entitled Cours d'instrumentation, which included musical examples of principals discussed in the Traité. Both the Traité and the Cours were accepted by the Academy and adopted by the Paris Conservatoire.
jn4.gesture: An interactive composition for dance.
jn4.gesture is an interactive multimedia composition for dancer and computer designed to extend the possibilities of artistic expression through the use of contemporary technology. The software produces the audiovisual materials, which are controlled by the movement of the dancer on a custom rug sensor. The software that produces the graphic and sonic material is created using a modular design. During run-time, the software's modules are directed by a scripting language developed to control and adjust the audiovisual production through time. The visual material provides the only illumination of the performer, and the projections follow the performer's movements. The human form is isolated in darkness and it remains the focal point in the visual environment. These same movements are used to create the sonic material and control the diffusion of sound in an eight channel sound system. The video recording of the performance was made on April 22, 2002. The work was produced in a specialized performance space using two computer projectors and a state of the art sound system. Arleen Sugano designed the costumes, choreographed and performed the composition in the Merrill Ellis Intermedia Theatre (MEIT) at the University of North Texas. The paper focuses on the design of the program that controls the production of the audiovisual environment. This is achieved with a discussion of background issues associated with gesture capture. A brief discussion of human-computer interface and its relationship with the arts provides an overview to the software design and mapping scenarios used to create the composition. The design of the score, a graphical user interface, is discussed as the element that synchronizes the media creation in "scenes" of the composition. This score delivers a hybrid script to the modules that controls the production of audiovisual elements. Particular modules are discussed and related to sensor mapping routines that …
Journey for Jazz
This written thesis accompanies a 32-minute documentary video, Journey for Jazz, which explores four Korean students who major in jazz at the University of North Texas in Denton. Detailed accounts of the pre-production, production, and post-production of the video guide the reader to understand the challenging and rewarding process of making this documentary. Theoretical issues are also discussed, including Bill Nichols's typology of documentary modes as a useful tool for analysis of hybrid documentaries and conventions of the observational and interactive mode in Journey for Jazz, which is considered a hybrid of both modes. The film focuses mainly on the scholarly and artistic experiences that the four students undergo while studying jazz in the United States.
Just $10 A Month: A Television Advertising Campaign
This written thesis accompanies three television public service announcement spots. Two of the spots are 60 seconds and one of the spots is 45 seconds in length. I produced this public service television advertising campaign to highlight the issue of child illiteracy in Pakistan and to encourage expatriate and resident Pakistani's to donate to educational charities. A Website created by the filmmaker is promoted in the campaign. This Website provides information about various charities that educate children in Pakistan. Detailed accounts of pre-production, production and post-production of the campaign allow the viewer to comprehend the challenges in producing television campaigns for social causes. Theoretical issues are also discussed, including the causes of illiteracy, the importance and role of social campaigns, the history and uses of propaganda as well as the aesthetic concerns of a public service campaign producer. I discuss the importance of creating the culture of public service campaigns in a third world country like Pakistan, and states that the Pakistani community needs to look inwards to overcome the challenge of illiteracy.
Latin Mass for Choir, Orchestra, Soprano and Mezzo-Soprano Soloists
The Latin Mass is a musical composition in five movements, scored for large choir, standard orchestra, and two soloists. The movements are the standard parts of the Roman Catholic Mass Ordinary. The language is set mainly in Latin with two exceptions: the Kyrie movement is set in Greek (which is the standard Roman Catholic setting), and the Credo is simultaneously recited in English and sung in Latin. The work is scored using conventional notation techniques and employs rather conservative technical demands on both the choir and orchestra. No extended techniques are required of any of the performers. It is set in a modal harmonic language.
