Primary Stylistic Characteristics of Cindy McTee's Music as found in Timepiece, Ballet for Band and Finish Line
Cindy McTee, Regents Professor of Composition in the College of Music at the University of North Texas, is one of America's leading composers. Her music is an eclectic blend of the "American" sound that is created by the use of a multiplicity of techniques. This document uses three of McTee's most recent (to date) works for wind band: Timepiece, Ballet for Band and Finish Line, to identify the primary stylistic characteristic's of the composer's music, which include: jazz influence; use of ostinati, pseudo-ostinati and machine-like rhythmic patterns and figures; creation of extended and angular melodic lines; progressive "walking" bass lines; and the use of octatonic and chromatic collections. Through the identification of stylistic characteristics, concise stylistic analysis of the works, interview transcript, list of composer's works to date, and selected discography, this document will add to the limited body of scholarly writing on the composer.
La Primavera: Concertino for English Horn and Chamber Orchestra
La Primavera: Concertino for English Horn and Chamber Orchestra is a work in a traditional chamber orchestra instrumentation: single woodwinds (flute, oboe, clarinet, and bassoon), two French horns, trumpet, timpani and strings. A through-composed work of 14 minutes in duration, the Concertino is conceptually based on the idea that spring is not the first of the seasons, but rather the last. As a result, all of its motivic materials are organically linked to one another, and function as paired forces that struggle for supremacy. The introduction of the third motive functions as a motivic synthesis, since it contains intrinsic elements of previous motives. There are several important compositions based on the topic of the seasons among them we find: Vivaldi's Concerto Grosso Le Quatro Staggione, Haydn's oratorio The Seasons, and Piazzola's chamber work Las Estaciones. While researching this topic, the conceptual dilemma of spring as the last season was considered. This became a turning point in the compositional process strong enough to consider the spring as a singular topic of interest. The analysis of this work through Derrida's Deconstruction theory first came to me while reading Rose Rosengerd Subotnick's Deconstructive Variations: Music and Reason in Western Society. The Linguistic approach, was inspired in part by Leonard Bernstein's lecture “The Unanswered Question,” and Jean J. Nattiez's Music and Discourse: Toward a Semiology of Music.
Prime Ideals in Commutative Rings
This thesis is a study of some properties of prime ideals in commutative rings with unity.
Primitive Substitutive Numbers are Closed under Rational Multiplication
Lehr (1991) proved that, if M(q, r) denotes the set of real numbers whose expansion in base-r is q-automatic i.e., is recognized by an automaton A = (Aq, Ar, ao, δ, φ) (or is the image under a letter to letter morphism of a fixed point of a substitution of constant length q) then M(q, r) is closed under addition and rational multiplication. Similarly if we let M(r) denote the set of real numbers α whose base-r digit expansion is ultimately primitive substitutive, i.e., contains a tail which is the image (under a letter to letter morphism) of a fixed point of a primitive substitution then in an attempt to generalize Lehr's result we show that the set M(r) is closed under multiplication by rational numbers. We also show that M(r) is not closed under addition.
Primitivism and Progress in the Fiction of George S. Perry and Fred Gipson
This thesis examines the degree of primitivism in the fiction of George Sessions Perry and Fred Gipson for the purpose of determining their respective attitudes toward the effect of modern technology on rural Central Texas.
Prince Hall Freemasonry: The other invisible institution of the black community.
The black church and Prince Hall Freemasonry both played important roles in the black experience in America. Freemasonry and the black church; one secular, the other spiritual, played equally important, interrelated roles in the way the black community addressed social, political, and economic problems in the eighteenth and nineteenth centuries.
Principal Leadership Behaviors that Affect Teacher Collective Efficacy
Research continues to support the positive link between teacher collective efficacy and student achievement. The purpose of this study was to better understand how principal leadership behaviors affect teacher collective efficacy beliefs. The study was designed around Goddard, Hoy, and Hoy's construct of teacher collective efficacy, which is grounded on Bandura's efficacy constructs. The sequential mixed-methods study was designed to examine the perceptions of teacher participants from one Texas Title I middle school regarding principal leadership behaviors. A case study approach was used to construct meaning from teachers' perceptions about the effects of principal behaviors on teachers' beliefs regarding the components of collective efficacy. The quantitative portion of the study (a survey) examined teacher perceptions of their collective efficacy beliefs regarding various facets of the school organization. The qualitative portion (focus group and individual interviews) centered on what teachers perceive to be the impact of principal leadership behaviors on their teacher collective efficacy. Findings from the quantitative portion of the study suggest that teachers perceive their levels of collective efficacy to be higher when reflecting on factors that are primarily connected to school, like learning, motivating students, and handling student discipline issues. Findings from the qualitative portion of the study suggest that when principals exhibit collaboration, empowerment, relationship building, and trust, teachers perceive the leader to be effective. The study was limited to one Title I middle school so an extension to the study which would include other middle or additional high schools is recommended.
Principal Professional Development and the Effect of a Structured Management Effectiveness Profile
An activity for principal improvement that has not received much attention is the structured management effectiveness profile. The concept is to provide the principal and a group of teachers at that campus with an opportunity for assessment of the principal's management and leadership skills. A comparison between the two provides the principal with information on their perceived management strengths and weaknesses. One such profile, available through the American Association of School Administrators is the Educational Administrator Effectiveness Profile (EAEP). The EAEP was originally given to 66 principals in Tarrant County, Texas. This study reports the results of reassessment of 40 of those principals after a five year period.
Principal Professional Development for Building Leadership Capacity
The findings of this study serve as an exploratory case-study examining the conditions of professional learning for in-service principals in one north Texas suburban district with changing student demographics. Quantitative and qualitative analysis of a variety of data collected sought to reveal how professional development of principals increased a principal's contingent leadership skills to positively affect student achievement through school improvement efforts. Perceptions were examined from the sample of seven executive directors at the district level; six campus principals (two elementary, two middle, and two high school); and eight teachers selected from among four of the six campuses whose principal participated in a semi-structured interview. Additionally, responses from a principal survey were examined. Findings were organized around three themes that surfaced from the deductive and inductive analysis of data collected in response to the three research questions. The themes were: instructional leadership and other principal responsibilities, principal professional development and components of professional learning, and measuring the effectiveness of principal professional learning. Findings revealed that there are many offerings of professional development opportunities available to principals in Learning ISD. The components essential in effective principal professional learning opportunities in the studied district consisted of embedding social capital, professional capital, and decisional capital to develop contingency leadership skills. Measuring the effectiveness of principal professional learning remains an area of growth for the district studied as well as the adherence to a meaningful principal evaluation system that can properly quantify and qualify a campus administrator's effect on school improvement and student learning.
Principals' Leadership Beliefs: Are Personal and Environmental Influences Related to Self-Efficacy?
The purpose of this study was to determine if there was a relationship between principal self-efficacy and personal characteristics, school conditions, and professional preparation among a selected group of Texas, public school principals. The survey instrument included the Principal Self-Efficacy Scale (PSES) developed by Tschannen-Moran & Garies in 2004, and other items. The survey instrument was electronically distributed to a random sample of 965 Texas, public school principals. From that population, 289 principals completed the survey for a response rate of 30%. Statistical Package for the Social Sciences (SPSS) was used for the analyses which included descriptive statistics, correlations, and analysis of variance. Additionally, factor analysis and reliability were calculated for the PSES. The factor structure and reliability found in this study closely mirrored the results of earlier investigations, providing further support for the reliability and validity of the PSES. Out of 12 variables examined in relation to principal self-efficacy, a statistically significant relationship was found for gender, years of teaching experience, level, SES, parental involvement, and student discipline. However, all six of the statistically significant variables had a small effect size indicating limited practical significance. The results of this study support the need for continued research of principal self-efficacy beliefs. Principal self-efficacy research may help explain the relationships between effective principals and effective schools.
Principals' Perceptions of Organizational Practices and Decision Making Roles in Middle Level Schools
The problem addressed in this study was whether middle level schools have adopted currently held research findings with respect to organizational structure and decision making processes promoted by the work of the Carnegie Foundation and various state agencies. Purposes included determining the perceptions of principals in schools utilizing interdisciplinary teams of teachers regarding the roles of principals and teachers in decision making processes, differences in campus performance on the Texas Assessment of Academic Skills and specific demographic variables in comparison to perceptions of principals in schools not utilizing interdisciplinary teams on these same questions.
Principal's Role Behavior and Administrative Performance as Perceived by Selected Teachers
This study was based on the assumption that classroom teachers were in an advantageous position to judge their principal's role behavior and their principal's administrative performance. The problem of this study was to determine whether or not significant differences existed between teachers' perceptions of their principal's role behavior; whether or not significant differences existed between teachers' perceptions of their principal's administrative performance; and whether or not there was any relationship between teachers' perceptions of their principal's role behavior and his administrative performance. The findings in this study led to the following conclusions: Factors such as sex, education level, teaching experience, school level, school size, and school district do not effect principal’s behavior or administrative performance. However, differences were found in teacher perceptions for teachers with 5 years or less of teaching experience, rural/urban school setting, principal’s sex don’t differ in their role behavior; differing instead in educational leadership ability. It is concluded that principals are least effective in the area of educational leadership when comparing the four areas of administrative decision-making, communications, general administrative behavior, and educational leadership. They are most effective in general administrative behavior. Principals, in general, tend to exhibit transactional behavior. The majority of teachers do not indicate that their principal's role behavior has any relationship to their administrative performance as school principals.
The principle of "sankofa" in elementary music instruction in southern Ghana: selected school personnel's views of and their role in its implementation
The study ascertained elementary school teachers' and supervisors' views about their role in the implementation of Sankofa (Go back and retrieve) in school music. Sankofa mandates the integration of distinctive Ghanian traditional values and practices with Western educational concepts in the school curriculum. In music, it calls for the fusion of multi-ethnic musics of Ghana with Western musical concepts in public school music instruction. Some concerns expressed by Ghanian music educators regarding teachers' negative attitudes toward Sankofa in public school music had prompted the study.
Principle or Political Expediency: The Progressive Republicans, 1910-1916
Progressivism, which had invaded the conservative-controlled Republican party, provoked a split that affected local politics as well as the party's national leadership. The rebellion engulfing the party demanded that each Republican clearly define his position.... The available choices, ranging from reaction to insurgency, required that the professional Republican politician be painfully specific. The dilemma faced by these politicians, particularly those of the rank and file who were sympathetic with progressive ideals, is the major concern of this study.
Principles and Application of Numerically Controlled Machines
The purpose of this study is threefold. First, numerical control will be analyzed objectively to ascertain its justification in terms of meeting the requirements of the basic manufacturing process phases. Secondly, the study will consist of an evaluation of the field of industrial arts in the Dallas-Fort Worth area to determine how numerical control has been accepted in the educational field and what preparation, if any, is being made to include the teaching of this new industrial concept. Thirdly, the study will investigate the feasibility and cost of installing numerically controlled equipment in the industrial arts laboratories of North Texas State University.
Principles for Formulating and Evaluating Instructional Claims
The problem with which this investigation is concerned is that of developing (a) the concept of instructional claim, and (b) credible principles for instructional claim formulation and evaluation. The belief that these constructions are capable of contributing to the advancement of curricular and instructional research and practice is grounded in three major features. The first feature is that of increased precision of basic concepts and increased coherence among them. The second feature is the deliberate connecting of instructional strategies and goal-states and the connecting of instructional configurations with curricular configurations. The third feature is the introduction of fundamental logical principles as evaluative criteria and the framing of instructional plans in such a way as to be subject to empirical tests under the principles of hypothesis testing that are considered credible in the empirical sciences.
Principles Underlying a Program of Education for Nazi Germany
The purpose of this study is to point the directions a program of education might take in providing opportunities for the members and followers of the defeated Nazi political party of Germany to find their ways into normal constructive living in a new political order.
Print Making in the Junior High School
The general purpose of this investigation is to examine the values of print making as compared with drawing and painting in their respective relationships as a part of the junior-high-school art program. The specific purposes of the investigation are: 1. To determine the values which are common to both the print-making arts and the drawing-painting arts. 2. To discover the values which are unique in the print-making arts. 3. To determine which of the print-making processes belong in the junior high school. 4. To recommend the grade placement and limitations of print-making for the junior high school. A conservative general conclusion, based upon objective evidence, can safely be drawn to the effect that in all phases of the learning experiences print making was found to be as valuable as painting and drawing. Its values were compared with respect to specific art development, to general educational growth, to socialization, and to character training.
Printmaking from 1400 to 1700 with a Catalogue of the Print Collection at the Dallas Museum of Art
Because the Dallas Museum of Art has not compiled a catalogue of its graphic collection, the researcher has written a comprehensive catalogue of the museum's prints in conjunction with a history of printmaking from 1400 to 1700. The sources of data include observation of the prints plus catalogue raisonnés of major printmakers, and books and articles on printmaking. The thesis is organized as follows: a history of printmaking, which is divided into three chapters, Woodcut, Engraving, and Etching, and a catalogue which cites the pertinent data on each print. Gaps in the collection and recommendations for future acquisitions are discussed in the preface to the catalogue.
Priorities for the Governance of Texas Student Teaching Programs
The problem of this study is differences in perceptions of priorities in selected areas of student teaching existing within the governance set, i.e., university directors of student teaching, public school administrators charged with implementing Senate Bill Eight, and presidents of local units of the Texas State Teachers Association. Six areas were chosen as the focal point of the study: selection of student teachers, selection of cooperating teachers, selection of college coordinators, placement of student teachers, evaluation of student teachers, and expenditure of Senate Bill Eight funds designated for the support of student teaching programs. The study concluded that the governance set is in overall agreement concerning the ordering of priorities. However, some significant differences were manifested concerning the implementation of specific priorities. Disagreements were noted in the following areas: selection body for student teachers, selection body for cooperating teachers, selection body for college coordinators, minimum grade point averages in education courses, and minimum grade point averages in major area courses.
Priorities of the Professoriate in Historically Black Private Colleges and Universities
The intent of the study was to ascertain the importance faculty at Historically Black Private Colleges and Universities in Texas place upon academic activities of research, teaching and service. A survey of faculty at 4 historically black private colleges and universities in Texas (HBCUs) was conducted to collect data from 158 faculty members; 107 usable questionnaires were returned. A response rate of 67.7 percent was achieved. The pattern that emerged from the data indicates the HBCU faculty in this study lean toward teaching and service as being a viable measure for tenure and promotion. The HBCU faculty in this study should remain cognizant that they are an intricate element within the higher education discipline. According to the perceptions of the HBCU faculty, several indicated that their college/university is important; however, they indicated that their academic discipline is less important in comparison. According to the perceptions of the HBCU faculty, many respondents indicated that their job is a source of considerable personal strain. A comparison with the findings of the 1989 Carnegie Foundation for the Advancement of Teaching reveals more similarities than differences.
Prison Inmates: Institutional Adjustment, Educational Levels, Recidivism, and Escapism, Related to 16 Personality Factor Scores
The present study investigated the relationship of 16 Personality Factor (16 PF) Scores to institutional adjustment, educational level, recidivism, and escapism of 665 prisoners in a maximum security prison. Two phases of data analysis were conducted. Multiple two-tailed Students' t tests resulted in significant differences on all 16 PF Factor Scores between prisoners and Cattell adult norm group. Significant differences were also found between prisoners and Cattell prisoner norms. In phase two, four multiple linear regression models were constructed. Significant 16 PF scales, age, and educational differences were found within the prisoner sample. Possible implications of the use of the 16 PF in regression models in paramorphic clinical prediction programs are discussed.
Prison Notes: an Introductory Study of Inmate Marginalia
This thesis introduces the study of inmate marginalia as a method for understanding inmates’ uses of texts in prison libraries and for understanding the motivations for these uses. Marginalia are the notes, drawings, underlining, and other markings left by readers in the texts with which they interact. I use the examples of the Talmudic projects to set a precedent for the integration of marginal discourses into the central discourse of society. Next, I discuss the arguments surrounding the use of texts in prison libraries, including an outline for an ideal study of inmate marginalia. Finally, I discuss the findings of my on-site research at four prison libraries in Washington State. After scanning evidence of marginalia from forty-eight texts, a relatively small sample, I divided the marginalia by gender of facility, genre of text, address of the marginalia, and type of marginalia and found statistically significant correlations (p < 0.05) between gender and genre, gender and address, gender and type, and genre and type. However, while these correlations are statistically weak and require further investigation, the statistically significant correlations indicate the potential for integrating inmate marginalia studies into the scholarly discussions regarding inmates’ interactions with texts in prison.
Prison Productions: Textiles and Other Military Supplies from State Penitentiaries in the Trans-Mississippi Theater during the American Civil War
This thesis examines the state penitentiaries of Louisiana, Arkansas, and Texas that became sources of wartime supplies during the Civil War. A shortage of industry in the southwest forced the Confederacy to use all manufactories efficiently. Penitentiary workshops and textile mills supplied a variety of cloth, wood, and iron products, but have received minimal attention in studies of logistics. Penitentiary textile mills became the largest domestic supplier of cloth to Confederate quartermasters, aid societies, citizens, slaves, and indigent families. This study examines how penitentiary workshops converted to wartime production and determines their contribution to the Confederate war effort. The identification of those who produced, purchased, distributed, and used penitentiary goods will enhance our knowledge of overall Confederate supply.
Prisoner classification by behavioral, biographical, and psychometric analysis in cross-validation of the Mini-mult prisoner questionnaire
The classification of adult criminal populations for training, treatment, and security purposes has been time-consuming and expensive. The main purpose of this study was to develop a classification system which considered a wide variety of behavioral, biographical, and psychometric variables and yet was efficient in terms of time and money.
Prisoner's Dilemma in Quantum Perspective
It is known that quantum strategies change the range of possible payoffs for the players in the prisoner's dilemma. In this paper, we examine the effect of the degree of entanglement in determining the payoffs. When both players play quantum strategies, we show that the payoff for both players is unaffected by the entanglement value and it leads to a new Nash equilibrium.
Prisoners of War in Texas During World War II
This study analyzes the prisoner of war program in Texas and evaluates the Army's role in carrying out this assignment. Additional questions were, how were POWs treated? What problems did they create? How did civilians react to the presence of 50,000 prisoners?
Prisoners' Self-Help Packets for Positive Behavioral Change
This study investigated the efficacy of bibiliotherapy in a correctional setting. Bibliotherapy (the utilization of books, pamphlets, or other literature) has been recommended as an adjunct to psychotherapy when professional time was at a premium or when the motivational level of the clientele was marginal. The experimental problem of this present study was to assess the usefulness of bibliotherapy in coping with psychological problems found within the correctional setting. This investigation was designed to explore the effects of two self-help packets on two diverse prison populations.
Privacy Concerns and Personality Traits Influencing Online Behavior: A Structural Model
The concept of privacy has proven difficult to analyze because of its subjective nature and susceptibility to psychological and contextual influences. This study challenges the concept of privacy as a valid construct for addressing individuals' concerns regarding online disclosure of personal information, based on the premise that underlying behavioral traits offer a more reliable and temporally stable measure of privacy-oriented behavior than do snapshots of environmentally induced emotional states typically measured by opinion polls. This study investigated the relationship of personality characteristics associated with individuals' general privacy-related behavior to their online privacy behaviors and concerns. Two latent constructs, Functional Privacy Orientation and Online Privacy Orientation, were formulated. Functional Privacy Orientation is defined as a general measure of individuals' perception of control over their privacy. It was measured using the factors General Disclosiveness, Locus of Control, Generalized Trust, Risk Orientation, and Risk Propensity as indicator variables. Online Privacy Orientation is defined as a measure of individuals' perception of control over their privacy in an online environment. It was measured using the factors Willingness to Disclose Online, Level of Privacy Concern, Information Management Privacy Concerns, and Reported Online Disclosure as indicator variables. A survey questionnaire that included two new instruments to measure online disclosure and a willingness to disclose online was used to collect data from a sample of 274 adults. Indicator variables for each of the latent constructs, Functional Privacy Orientation and Online Privacy Orientation, were evaluated using corrected item-total correlations, factor analysis, and coefficient alpha. The measurement models and relationship between Functional Privacy Orientation and Online Privacy Orientation were assessed using exploratory factor analysis and structural equation modeling respectively. The structural model supported the hypothesis that Functional Privacy Orientation significantly influences Online Privacy Orientation. Theoretical, methodological, and practical implications and suggestions for analysis of privacy concerns and behavior are presented.
Privacy Management for Online Social Networks
One in seven people in the world use online social networking for a variety of purposes -- to keep in touch with friends and family, to share special occasions, to broadcast announcements, and more. The majority of society has been bought into this new era of communication technology, which allows everyone on the internet to share information with friends. Since social networking has rapidly become a main form of communication, holes in privacy have become apparent. It has come to the point that the whole concept of sharing information requires restructuring. No longer are online social networks simply technology available for a niche market; they are in use by all of society. Thus it is important to not forget that a sense of privacy is inherent as an evolutionary by-product of social intelligence. In any context of society, privacy needs to be a part of the system in order to help users protect themselves from others. This dissertation attempts to address the lack of privacy management in online social networks by designing models which understand the social science behind how we form social groups and share information with each other. Social relationship strength was modeled using activity patterns, vocabulary usage, and behavioral patterns. In addition, automatic configuration for default privacy settings was proposed to help prevent new users from leaking personal information. This dissertation aims to mobilize a new era of social networking that understands social aspects of human network, and uses that knowledge to honor users' privacy.
Privacy Preserving EEG-based Authentication Using Perceptual Hashing
The use of electroencephalogram (EEG), an electrophysiological monitoring method for recording the brain activity, for authentication has attracted the interest of researchers for over a decade. In addition to exhibiting qualities of biometric-based authentication, they are revocable, impossible to mimic, and resistant to coercion attacks. However, EEG signals carry a wealth of information about an individual and can reveal private information about the user. This brings significant privacy issues to EEG-based authentication systems as they have access to raw EEG signals. This thesis proposes a privacy-preserving EEG-based authentication system that preserves the privacy of the user by not revealing the raw EEG signals while allowing the system to authenticate the user accurately. In that, perceptual hashing is utilized and instead of raw EEG signals, their perceptually hashed values are used in the authentication process. In addition to describing the authentication process, algorithms to compute the perceptual hash are developed based on two feature extraction techniques. Experimental results show that an authentication system using perceptual hashing can achieve performance comparable to a system that has access to raw EEG signals if enough EEG channels are used in the process. This thesis also presents a security analysis to show that perceptual hashing can prevent information leakage.
Privacy Preserving Machine Learning as a Service
Machine learning algorithms based on neural networks have achieved remarkable results and are being extensively used in different domains. However, the machine learning algorithms requires access to raw data which is often privacy sensitive. To address this issue, we develop new techniques to provide solutions for running deep neural networks over encrypted data. In this paper, we develop new techniques to adopt deep neural networks within the practical limitation of current homomorphic encryption schemes. We focus on training and classification of the well-known neural networks and convolutional neural networks. First, we design methods for approximation of the activation functions commonly used in CNNs (i.e. ReLU, Sigmoid, and Tanh) with low degree polynomials which is essential for efficient homomorphic encryption schemes. Then, we train neural networks with the approximation polynomials instead of original activation functions and analyze the performance of the models. Finally, we implement neural networks and convolutional neural networks over encrypted data and measure performance of the models.
Private Affections: Miscegenation and the Literary Imagination in Israel-Palestine
This study politicizes the mixed relationship in Israeli-Palestinian literature. I examine Arab-Jewish and interethnic Jewish intimacy in works by Palestinian national poet Mahmoud Darwish, canonical Israeli novelist A. B. Yehoshua, select anthologized Anglophone and translated Palestinian and Israeli poetry, and Israeli feminist writer Orly Castel-Bloom. I also examine the material cultural discourses issuing from Israel’s textile industry, in which Arabs and Jews interact. Drawing from the methodology of twentieth-century Brazilian miscegenation theorist Gilberto Freyre, I argue that mixed intimacies in the Israeli-Palestinian imaginary represent a desire to restructure a hegemonic public sphere in the same way Freyre’s Brazilian mestizo was meant to rhetorically undermine what he deemed a Western cult of uniformity. This project constitutes a threefold contribution. I offer one of the few postcolonial perspectives on Israeli literature, as it remains underrepresented in the field in comparison to its Palestinian counterparts. I also present the first sustained critique of the hetero relationship and the figure of the hybrid in Israeli-Palestinian literature, especially as I focus on its representation for political options rather than its aesthetic intrigue. Finally, I reexamine and apply Gilberto Freyre in a way that excavates him from critical interment and advocates for his global relevance.
Private Beliefs of America's Financial Analysts--1953
This study will furnish the reader with general and specific investment advice as taken from questionnaires sent to a group of men who specialize in giving investment and financial advice -- financial analysts.
Private Group Influence in Public Policy Formulation: The Dallas Motion Picture Classification Ordinance of April 5, 1965
This thesis is an account of the events surrounding the passage of the Dallas Motion Picture Classification Ordinance of April 5, 1965. A stalemate between two disputing private factions in the city leads to public policy in the form of a municipal ordinance. Litigation quickly follows, and in the final analysis, a judicial determination temporarily ends the controversy...This investigation reveals that the council did not formulate public policy of its own volition, but only acted as an extension of the private struggle which had lasted for approximately thirty-six months.
Private Property in America: Land Use and the Ethics of Owning Land
Private property in the United States arose out of a tradition that emphasized the individual freedom to control holdings without interference from governmental influences. A sharp distinction between society as a whole and individual rights isolated ownership of private property from a notion of the common good. This dualistic framework excludes the possibility for forms of property that do not fall completely into either category. Property ownership attitudes are central to issues that often divide environmentalists and landowners. Property rights must be put in the context to understand the divergence between landowner attitudes and provisions made when the institution of private property was created. Finally, land itself as a type of property should be considered ethically distinct from other forms of property because of the interdependencies of human and nonhuman interests that the science of ecology has revealed.
Proactive Inhibition in Short-Term Memory
Experimental evidence was needed to help answer the question of whether the decrease in retention from Trial 1 to Trial 2 was caused by PI from Trial 1 decreasing retention of Trial 2, or by a primacy effect increasing retention of Trial 1 over the natural retention baseline of a S. The present experiment was designed to help answer this question.
Probabilistic Analysis of Contracting Ebola Virus Using Contextual Intelligence
The outbreak of the Ebola virus was declared a Public Health Emergency of International Concern by the World Health Organisation (WHO). Due to the complex nature of the outbreak, the Centers for Disease Control and Prevention (CDC) had created interim guidance for monitoring people potentially exposed to Ebola and for evaluating their intended travel and restricting the movements of carriers when needed. Tools to evaluate the risk of individuals and groups of individuals contracting the disease could mitigate the growing anxiety and fear. The goal is to understand and analyze the nature of risk an individual would face when he/she comes in contact with a carrier. This thesis presents a tool that makes use of contextual data intelligence to predict the risk factor of individuals who come in contact with the carrier.
A Probabilistic Model for Evaluating Capital Investment Proposals for Petroleum Refineries
The purpose of this study was to develop a probabilistic model that could be used by petroleum refiners to evaluate the economic potential of refinery capital investment proposals. The following two requirements were placed on the development at the outset: (1) that the model use linear programming to simulate refinery operations; and (2) that the model keep computer time within reasonable bounds. A probabilistic model was developed that requires the following steps for its application: (1) use linear programming to simulate both the operations of the existing refinery and the operations assuming that the investment is made; (2) select two variables that can be treated as probabilistic variables and assign either a theoretical or a subjective probability distribution to represent future values for the two variables; (3) develop return on investment interpolation data by computing a return on investment for all pair combinations of three tenth year values for each of the two probabilistic variables; (4) develop a return on investment distribution by selecting values at random from the two probability distributions and interpolating among the interpolation data to obtain return on investment data; (5) interpret the return on investment distribution. The model was applied to an actual refining situation that involved determining the expected internal rate of return of a proposed hydrocracker addition to a United States refinery. Total computer time required to evaluate the hydrocracker proposal was about 159 minutes. Accuracy of the interpolation feature of the model was also determined during the application. The average error of ten interpolated return figures that were selected at random for the accuracy check was 1.89 per cent.
Probabilistic Modeling for Whole Metagenome Profiling
To address the shortcomings in existing Markov model implementations in handling large amount of metagenomic data with comparable or better accuracy in classification, we developed a new algorithm based on pseudo-count supplemented standard Markov model (SMM), which leverages the power of higher order models to more robustly classify reads at different taxonomic levels. Assessment on simulated metagenomic datasets demonstrated that overall SMM was more accurate in classifying reads to their respective taxa at all ranks compared to the interpolated methods. Higher order SMMs (9th order or greater) also outperformed BLAST alignments in assigning taxonomic labels to metagenomic reads at different taxonomic ranks (genus and higher) on tests that masked the read originating species (genome models) in the database. Similar results were obtained by masking at other taxonomic ranks in order to simulate the plausible scenarios of non-representation of the source of a read at different taxonomic levels in the genome database. The performance gap became more pronounced with higher taxonomic levels. To eliminate contaminations in datasets and to further improve our alignment-free approach, we developed a new framework based on a genome segmentation and clustering algorithm. This framework allowed removal of adapter sequences and contaminant DNA, as well as generation of clusters of similar segments, which were then used to sample representative read fragments to constitute training datasets. The parameters of a logistic regression model were learnt from these training datasets using a Bayesian optimization procedure. This allowed us to establish thresholds for classifying metagenomic reads by SMM. This led to the development of a Python-based frontend that combines our SMM algorithm with the logistic regression optimization, named POSMM (Python Optimized Standard Markov Model). POSMM provides a much-needed alternative to metagenome profiling programs. Our algorithm that builds the genome models on the fly, and thus obviates the need to build …
The Probable Effect of the 1936 and the 1940 Ruling of the State Board of Education of the State of New Mexico on the High School Principal
The purposes of this study, dealing primarily with the principals of the four-year high school who are affected by the administrative requirements, are to determine (1) the probable effect of the higher standards upon the principals as judged by their responses in meeting the requirements of the 1936 ruling, (2) whether the State, the principal, or both are paying for the improvement of the administration in the public schools resulting from the 1936 ruling, (3) attitudes that resulted from the conditions arising from the demands of the standards of the 1936 ruling, and (4) the probable result of the 1940 ruling.
Probation and Constitutional Protection
This thesis analyzes the relationship between constitutional protections and probation in America. That relationship is not a clear one because traditional protections of individual rights focus on the person accused of a crime while probation focuses attention on the convicted defendant. Students of public law have paid little attention to the defendant following his conviction.
Problem-Based Learning for Training Teachers of Students with Behavioral Disorders in Hong Kong
This study attempts to explore the perceived value of Problem-Based Learning (PBL) in training teachers of students with behavioral disorders (E/BD) in Hong Kong. It represents an effort to improve the predominately lecture focussed approach adopted in many preparation programs. Data on the training needs of Hong Kong teachers were also acquired and 31 knowledge/skills areas related to teaching students with E/BD were identified. Subjects viewed the PBL approach as dynamic, interesting and incentive driven. It develops skills involved in group learning, self-directed learning, use of information resources and problem-solving. Most important, teachers felt they were supported to explore the practical problems they personally encountered in the classroom and actions they could take to resolve them. Difficulties in using PBL included a lack of resources and the tendencies of most Chinese students to accept rather than challenge others' ideas.

The Problem of Spelling Reform
Spelling is a tool by which one records his thoughts and ideas; therefore it is a vital part of life. To fulfill its task successfully, spelling must be accurate. Spelling is that tool by which the happenings of the past are revealed to the present and are preserved for the future. For any individual who attempts to transfer his thoughts and words by symbols onto paper, correct spelling is a prime essential. It follows, then, that to develop perfect habits of spelling in order that perfect transcriptions of thoughts might be made is the duty of the teacher. This duty has been attempted by teachers for many generations. But it is an established fact that the goal has not been reached, for there is a stupendous number of misspellings in the written work of students in high schools. Many methods have been advanced for correcting this incompetence in spelling; when these were tried, they have failed to secure the coveted goal. In some instances the cure has aggravated the disease. Successful abolishment of this handicap baffles the teaching profession. In a course in American pronunciation recently conducted at North Texas State College, the teacher presented the fact that there are factors in the English language which tend to become stumbling-blocks to the attainment of perfect spelling. For the first time it became evident to this writer that certain elements within the language might be the cause of the spelling problem. Therefore, the readings for this thesis were undertaken for the purpose of finding the logical causes for poor spelling habits and with the hope of discovering a workable remedy.
Problem of the Arrangement for Two Pianos of Iberia by I. Albeniz
The literal meaning of "transcription" is "written across"; in freer terminology it is "the musical counter-part of literary translation." The terms "arrangement" and "transcription: are used synonymously by nearly all musical dictionaries. However, even then , there is often a distinction made, an arrangement being considered to adhere strictly to the original text while a transcription admits of creative participation on part of the arranger, ranging from the simple transference of musical medium to the complete reworking of a composition with additions and modifications.
Problem of the Arrangement for two Pianos of Sedlak by Jindr. Jindrich and Prelude, op. 34, no. 5, by Dmitri Shostakovich
This study was prompted by the writer's interest and experience in the field of two-piano performance. At the beginning of this writer's two-piano work the available material was scarce, and much of it was inadequate in quality from the standpoint of both composition and arrangement. It seems strange that this particular form of chamber music, so delightful to play and so enjoyable to listen to, did not completely take popular fancy until the twentieth century. During the past ten years however, teachers are realizing the benefits derived from training students in two-piano playing. There is no doubt in the writer's opinion that two-piano concerts will henceforth always be in demand.
The Problem of the Artist in Society : Hawthorne, James, and Hemingway
The relationship of James to Hawthorne and of Hemingway to James certainly indicates the close literary relationship of the three writers. This development makes it seem only natural that three such self-conscious artists would have recourse to similar interests and would employ in their writings common themes, ideas, and methods.
The Problem of the Hero in Shakespeare's King John
This thesis is an attempt to evaluate the evidence for and against the presence of a hero in King John. As such, it is actually a search into the artistic abilities which Shakespeare exercised in this drama to determine whether he created a dramatic work of art which merits recognition for its own sake.
Problem-oriented approach to criminal investigation: implementation issues and challenges
As a proactive, information-based policing approach, problem-oriented policing emphasizes the use of crime analysis techniques in the analysis of the underlying causes of the problems that police deal with. In particular, analysis applications can be powerful tools for criminal investigation, such as crime reconstruction, profiling, IAFIS, VICAP, and CODIS. The SARA Model represents a problem-solving strategy of problemoriented policing. It aims to address the underlying causes of the problems and create substantial solutions. However, implementing problem-oriented policing requires a significant change in both the philosophy and structure of police agencies. Not only American policing but also the Turkish National Police should consider problem-oriented policing as an alternative approach for solving criminal activities.
