The Most Important Educational Problems Affecting the Growth of Elementary Schools of Texas, 1972
The problem with which this investigation is concerned is the identification of conditions, situations, and events that are important problems faced in the public elementary schools of Texas. Problems are categorized into sixteen areas: finance, desegregation and busing, school organization, school personnel, preschool and kindergarten, instructional improvement, reporting systems, pupil behavior, curriculum, in-service staff training, humanizing the schools, public relations, minority groups, migrant children, special education, and recent trends. The purpose of the study is to determine perceived importance of problems and to establish priorities of current issues from information obtained from education leaders of elementary schools. digital.library.unt.edu/ark:/67531/metadc164583/
Mother-child Relations and Social Expectations of Normal Children and Those with Learning Disabilities
The study explored the possibility that the perceived mother-child relationship of children with learning disabilities differs from that of normal children. It was further hypothesized that the manner in which the child perceives his relationship to his mother is related to the perception he has of his society in general. digital.library.unt.edu/ark:/67531/metadc164090/
Mothers' and Fathers' Parenting Characteristics in Relation to Family Earner Status and Self-perceived Interpersonal Competence
With an increasing number of married mothers who participated in paid work roles, fathers with full-time employed spouses now are expected to assume the role of caregiver and have higher frequency of engagement in parenting practices. This study of 235 university students from dual-earner and single-earner families investigated their retrospective perceptions of both mothers' and fathers' frequency of engagement in overall and specific parenting behaviors. These perceptions were measured by the Parent Behavior Frequency Questionnaire-Revised Scale, which includes seven parenting characteristics and related behaviors. Paired samples t-tests suggested that married mothers, whether fully employed outside the home or not, engaged more frequently, than their full-time employed spouses, in parenting characteristics related to bonding, education, general welfare and protection, responsivity, and sensitivity. However, mothers' employment status had little influence upon the frequency at which either parent engaged in any of the seven parenting characteristics and related behaviors. University students who perceived that both parents were more frequently engaged in specific parenting behaviors related to education, responsivity and sensitivity rated themselves higher on interpersonal competence, as measured by the Interpersonal Competence Questionnaire-Revised Scale. Students who perceived that both parents were less frequently engaged in negative parenting behaviors rated themselves higher on competence in conflict management. In addition, family earner status had no significant impact on university students' levels of interpersonal competence. Although there was no significant gender difference in the levels of total interpersonal competence, male students reported higher levels of interpersonal competence in the domains of asserting influence and conflict management than their female counterparts. These findings revealed that like parents from single-earner families, parents from dual-earner families also demonstrated a significant discrepancy in the frequency of engagement in parenting practices. Mothers still invested considerably more time with their children than do fathers. Therefore, there may be a need to develop parent education programs for fathers so that they have opportunities to shape paternal identity and parental self-efficacy. Also, it is necessary to develop friendly family- employment policies and enhance social support networks that enable both full-time employed mothers and fathers to achieve a satisfactory balance between family and work. digital.library.unt.edu/ark:/67531/metadc177184/
Mothers as Play Therapists for their Children
The problem with which this investigation is concerned is that of determining whether previously untrained, non-professional personnel, in this case mothers, can be trained to undertake and cope with the responsibilities of a play therapy situation with their own children. The hypothesis of this study is that by placing mothers in such a situation, the mother's ability to communicate with her child will be modified as well as modifying the child's perception of her as a warm and accepting parent. digital.library.unt.edu/ark:/67531/metadc131330/
Mothers' Perceptions and Preschoolers' Experiences: Cultural Perspectives of Early Childhood Education
In this qualitative investigation, the ways in which four ethnically diverse mothers' perceptions of early childhood education combined with the school experiences of their children were examined. Research tools included audiotaped interviews with Mexican-American, Korean-American, African-American, and Anglo mothers; videotaped school experiences; and a video message with a viewing guide requesting written reaction. digital.library.unt.edu/ark:/67531/metadc278495/
Motion Versus Non-Motion in Interactive Video Lessons in High School Physical Science
The most important question addresed in this study was whether there is any difference in student learning between a motion group and a non-motion group. The interactive video courseware is currently a part of the curriculum in this district. It was used in its original form with the contrast group. For the experimental group one unit of the courseware was modified to remove the motion video and replace it with photorealistic graphics that served as the non-motion part of the study. Covariates were selected to compensate for any differences in the two groups. A pretest and posttest was administered to both groups. Analysis of the posttest scores indicated that there was no difference in learning if motion in the presentation was the only variable. digital.library.unt.edu/ark:/67531/metadc279141/
Motivating Factors for Philanthropy at a Ministry Preparation Graduate Institution
A qualitative case study was conducted to determine whether major donors to an institution of higher education that existed to prepare ministers and missionaries were perceived by the institution's leaders as motivated by organizational effectiveness, financial efficiency, or evaluations by donor watchdog agencies. The case study was conducted with the Graduate Institute of Applied Linguistics. The interview process was utilized to gain information individually from the president, a development consultant, an academic dean, and a former development director. Each participant was asked a series of 19 questions during the interview process. The results indicated that the leaders perceived that organizational effectiveness was a philanthropic motivator for major donors and measured it by the accomplishments of those who were trained at the institution. The results also indicated that the ministry preparation institution's leaders perceived financial efficiency to provide philanthropic motivation to major donors, though to a lesser degree than organizational effectiveness, and measured it by stewardship of funds. The results further indicated that the ministry preparation institution's leaders perceived that donor watchdog agency evaluations, specifically those of the Evangelical Council for Financial Accountability and Guidestar, provided philanthropic motivation for major donors. Additional research recommendations included studying how to report about organizational effectiveness in a manner meeting the needs of major donors and what motivates major donors of other education and nonprofit organizations, organizational effectiveness and/or financial efficiency. digital.library.unt.edu/ark:/67531/metadc271886/

Motivation and Resilience in Art Education: Insight and Inspiration From the Lives and Careers of Two Taiwanese College Art Teachers
Access: Use of this item is restricted to the UNT Community.
This narrative study explores how two Taiwanese college art teachers’ lives and teaching experiences illustrate the ways they cultivate resilience and motivation to sustain professional commitments amidst challenges in their teaching careers. I use the life story interview as my methodology and a three-dimensional space approach to code and analyze my data to retell their stories about how resilience and motivation have guided them as they negotiated dilemmas in teaching. The participants’ stories demonstrate that in order to be motivated, teachers must satisfy their basic needs, which, in the language of Maslow’s need theory, include secure income, safety, love and belonging, respect, and personal accomplishment. To be resilient, art teachers need to facilitate self-efficacy as an essential belief to face challenges, and they also must gain support from family members, students, school administrators, and fellow members of professional organizations as external support resources. This study also illuminates the significance of international educational exchanges, the teaching knowledge constructed through layers of life and professional experience, and the importance of creating dialogue to address teachers’ challenges. Recommendations for future study include exploring further the relationship between motivation and resilience, specifying how gender difference affects the ways participants tell their stories, investigating how teachers in diverse cultural and geographical settings develop motivation and resilience, considering how teachers construct career-affirming memories from both positive and negative life experiences, and exploring uses of social media to engage a broader audience, sharing participants’ stories without the limitations of time and space. digital.library.unt.edu/ark:/67531/metadc149570/
The Motivation of Characters in Othello, King Lear and Macbeth
By examining the critical comment of some of the best known critics, who fall roughly into two groups, the philosophical or psychological on the one hand, and the realistic on the other, I have endeavored to gather the ideas they have advanced in regard to the motives of them main characters from three of Shakespeare's tragedies--Othello, King Lear, and Macbeth. It is evident that the discussion of motives has not been the main consideration of any one of them, though the problem has naturally arisen in the analyses of characters and explanations of plot and dramatic art. Consequently it will be my purpose to study these plays from the standpoint of the motivation of the characters, having in mind two objects: the determination of which motives Shakespeare took from the sources of the plays and which ones he himself attributed to the characters, and the determination of which group of critics, the psychological or the realistic, is more nearly correct in their contentions in regard to the motivation of characters in Shakespeare's plays. digital.library.unt.edu/ark:/67531/metadc75359/
Motivational Differences between High and Low Normal Groups
The need for a concise definition of the normal, healthy personality prompted a study of high normal and low normal students enrolled at North Texas State University. Such a definition would facilitate the activities of several areas of applied psychology--psychotherapy, quantification of objective means of rating the general health of an individual's personality, the development of criteria against which to measure the success of mental health clinic programs. digital.library.unt.edu/ark:/67531/metadc130556/
The Motivational Impact of Incentive Programs on Young Adult Employees in Corporate Casual Restaurants

The server and bar staff of the Chili's division of Brinker International, Inc. were surveyed in 18 stores in the Dallas area. From the sample. 356 usable surveys were received. The study was designed to obtain feedback about existing and future incentive programs that will enhance development of a positive working environment, along with higher productivity and a lower turnover rate. digital.library.unt.edu/ark:/67531/metadc278724/
Motives, Allusions, and Eclecticism: A Panametric Analysis of the First Movement of Christian Lindberg's Mandrake in the Corner based on the Method of Jan LaRue
For more than 20 years, Christian Lindberg has been internationally recognized as the premiere trombone soloist of our time. Few, however, are familiar with his compositions. For over ten years, he has composed many solo and ensemble works for trombone. Many prominent musical organizations in the world have performed Lindberg's music, including the Chicago Symphony Orchestra, the St. Paul Chamber Orchestra, and the University of North Texas Wind Ensemble. Today, Christian Lindberg has commission requests up to 2010. Christian Lindberg completed Mandrake in the Corner, a three movement concerto for trombone, in 1999. The purpose of this dissertation is to present an analysis of the first movement of Mandrake in the Corner to provide the first in depth study of Lindberg's compositional style. This analysis borrows freely from the method of Jan LaRue, which focuses on sound, harmony, melody, rhythm, and growth of musical structure on the small, middle, and large levels. The focus of this study centers on the aspects of melody, harmony, and rhythm to explain how the piece works despite the lack of a second theme or change of key in the first movement. digital.library.unt.edu/ark:/67531/metadc3603/
Motivic development in the piano music of Karl Weigl (1881-1949).
In discussing the music of Karl Weigl (1881-1949), it is essential to estimate the state of research regarding the composer and his professional life. Although a copious account and collection of Weigl's papers exists at Yale University, much contribution in the form of editions, recordings, and scholarly texts is needed. Schooled by Adler, Schoenberg, and Zemlinsky, Weigl graduated from the Musikacademie of Vienna in 1899 with high honors, with later employment in the Vienna Opera as a vocal coach (where he worked with such figures as Bruno Walter, Friedrich Weidemann, and Lotte Lehmann.). A theory and composition appointment to the New Vienna Conservatory after 1918 dramatically opened Weigl's professional horizons. With the rise of anti-semitism in Nazi Germany, Weigl and his family escaped to New York in autumn 1938. Eventually, Weigl obtained positions in the Hartt School of Music, Brooklyn College, Boston Conservatory, and finally, the Philadelphia Academy of Music in 1948. Although Weigl's music has been commented upon by Stephen Davison, Wendell Davis, and Michael Kater, much literature in the form of published analysis, commentary, and biography has yet to come forward. This paper principally covers Weigl's Night Fantasies, Op. 13 as well as the 28 Variations for Piano, Op. 15 and the expressionist conventions they contain. digital.library.unt.edu/ark:/67531/metadc5175/
Mouse cortical cholinergic neurons: Ontogeny of phenotypes in vivo and in vitro.
The development of cholinergic neurons in mouse frontal cortex was studied both in vivo and in vitro by immunocytochemistry with an antibody to choline acetyltransferase (ChAT), the enzyme responsible for acetylcholine synthesis. While cortical cholinergic neurons have previously been characterized in rat cortex, up until very recently, intrinsic cortical cholinergic neurons were considered to be absent in mouse, and little is known about their development or phenotypic characteristics. The present study found no ChAT-positive neurons in mouse frontal cortex on postnatal day 0 (P0, the day of birth). On P7 there were few, faintly stained, ChAT-positive neurons. The numerical density of ChAT-positive neurons increased substantially with age, from none on P0, to 9.2 + 1.4 on P7, to 14.8 + 0.9 on P16, and 41.6 + 3.9 in adulthood. Considering that the numerical density of total neurons decreases during this postnatal period, the data represent a marked developmental increase in the percentage of cholinergic neurons. The development of cholinergic neurons showed very similar timelines in rat and mouse frontal cortex. Cultures prepared from mouse frontal cortex on embryonic day 16 were maintained for 25, 76, or 100 days in vitro (div). The percentage of ChAT-positive neurons was considerably higher than in vivo, ranging from a mean 28% to 31% across the three age (div) groups. With increasing age of the cultures, the numerical density of total neurons and ChAT-positive neurons decreased while the percentage of ChAT-positive neurons did not change significantly. These observations suggest some temporal stability in the cultures. Using dual immunofluorescence, ChAT-positive neurons were tested for colocalization with GAD or TH. The majority of ChAT-positive neurons colocalized with GAD, both in vitro and in vivo. However, ChAT did not colocalize with TH, either in vitro or in vivo. Our comparison of intact frontal cortex and cultures suggest that while the percentage of cholinergic neurons was greater in the cultures, the cholinergic neurons developed phenotypic similarities in vitro and in vivo. digital.library.unt.edu/ark:/67531/metadc4890/

Moving in a New Direction: An Exploration in Kinetics
Movement, whether conveyed through an actual motion or a gestured implication, remains an underlying theme in my creative process that started with my earliest works. I explored different aspects of kinetic sculpture, because I am seeking new ways to create motion such as experimenting with circulating air, wind, and the use of water features. I created a series consisting of three to five kinetic sculptures which do not rely on sound or direct viewer manipulation. digital.library.unt.edu/ark:/67531/metadc4482/
Moving toward the 21st Century: American Association of Colleges of Nursing Guidelines and Baccalaureate Nursing Education
This study investigated current use of American Association of Colleges of Nursing guidelines in preparing the baccalaureate nurse graduate to practice nursing in the community health sector of the healthcare delivery system and use of community based healthcare delivery sites by baccalaureate programs located in non-urbanized and urbanized areas. The extent of guidelines adoption, plans by colleges not currently using them to do so in the future, and impact of accreditation visits on the adoption of the guidelines were also explored. A qualitative survey design was used to describe the use of AACN guidelines in the development of baccalaureate nursing education. digital.library.unt.edu/ark:/67531/metadc278423/
Mozartean Gesture and Rhetoric in Hummel's Concerto for Trumpet
Hummel's Concerto for Trumpet (Concerto a Tromba principale) is overtly operatic and is stylistically reminiscent of Mozart's Don Giovanni. Using the methodology of Leonard Ratner and Wye J. Allanbrook, it is possible to explore gesture and rhetoric in Hummel's Concerto for Trumpet and Mozart's Don Giovanni, and achieve a deeper understanding of the stylistic similarities shared between the two works. In the third movement, dance is the most significant link to Don Giovanni. In the second movement, Hummel alternates between the emotions of Donna Anna and Don Ottavio as they appear in act 1, scene 13. The first movement makes extensive use of contrasting topics identified with buffa and seria characters to advance the musical narrative. Comparing Hummel's concerto and Mozart's opera is a hermeneutical approach that illuminates several performance practice implications. Knowing the expressive similarities and rhetorical strategies common to both works clarifies several issues, such as tempo, ornamentation, and above all, expression. Though Mozart's Don Giovanni and Hummel's Concerto for Trumpet are unequal in significance, it would be valuable to any interpretation of Hummel's concerto if the performer and audience acknowledge that the work is rhetorically and stylistically similar to Mozart's Don Giovanni. digital.library.unt.edu/ark:/67531/metadc6062/
Mr. Citizen: Harry S. Truman and the Institutionalization of the Ex-Presidency
In the last two decades of his life, Harry S. Truman formally established the office of the ex-presidency in the public eye. The goals he wanted to accomplish and the legislation passed to help Truman achieve these aims led the way for Truman and other former presidents to play a significant role in American public life. Men who had occupied the nation's highest office had a great deal to offer their country, and Truman saw to it that he and other former presidents had the financial and the institutional support to continue serving their nation in productive ways. Although out of the White House, Harry S. Truman wanted to continue to play an active role in the affairs of the nation and the Democratic party. In pursuing this goal, he found that he was limited by a lack of financial support and was forced to turn to the federal government for assistance. While Truman was active for more than a decade after he left Washington, his two most important legacies were helping push for federal legislation to provide financial support for ex-presidents and to organize and maintain presidential libraries. Truman believed that these endeavors were a small price for the nation to pay to support thee former occupants of the nation's highest office. Furthermore, Truman believed that presidential libraries were essential in preserving and disseminating the history of the nation's highest office. Truman's other activities including heavy involvement in partisan affairs. While he tried unsuccessfully to determine the party's presidential candidates, his involvement in the Democratic party and attendance at partisan events displayed his level of commitment to the party and his determination to play a role in its activities. digital.library.unt.edu/ark:/67531/metadc278731/
Mr Secrets and Social Media: the Confession of Richard Rodriguez
Richard Rodriguez's works create troubling situations for many scholars. Though numerous critics see him as the penultimate Chicano writer, many others see his writing as only pandering to the elite. However, all politics and controversies aside, he is a writer whose ideas upon language and public confession have been revolutionary. Throughout the thesis, I argue that Rodriguez's ideas upon language and identity are applicable to the social media landscape that we reside in currently, especially the public confession. Also, I use deconstructionism, along with postmodern criticism, to illustrate the changing arc of Rodriguez's confession from his first autobiography to his final one. In his first memoir, Rodriguez remains in the closet upon his sexuality, and the reader only catches glimpses of the 'real' character inside his work. In the second memoir, the reader sees a better glimpse because of his coming out; yet, even in this regard, he does not do so wholly and still leaves his confession unfinished. By the third, he applies themes and problems seen in his first and second works to discuss our browning nature, and how we are all sinners and that we desire to confess our sins. In my assessment of Rodriguez, I argue throughout all my chapters upon a measure of irreconcilability between the private world of the Hispanic immigrant family and the public sphere that they are forced to inhabit because of his citizenship and education. This irreconcilability creates a drastic limiting of identity for the author that Rodriguez is forced to navigate which creates his desire for confession. digital.library.unt.edu/ark:/67531/metadc271788/
Muerte Y Soledad En La Poesía De Manuel Altolaguirre Ante El Exilio
This study focuses on the Spanish poet of the Generation of '27 Manuel Altolaguirre. The purpose of this thesis is to show how the poetry of Manuel Altolaguirre evolves in relation to specific issues. Specifically, I study the changes in his work in regard to the themes of death and solitude, resulting from exile in 1939, to be enriched by new experiences, many of them dramatic, taking more personal ways, while offering them a more profound and complex and even in regard to the subject of the poet's death comes to contemplate a more positive way. The thesis is divided into five chapters. Following the introduction, the second chapter focuses on Altolaguirre's biography and the Generation in 1927 while the third focuses and analyzes his poetry before his exile in 1939. The fourth chapter examines his poetry after exile until his death in 1959, while the fifth and last chapter concludes this study. digital.library.unt.edu/ark:/67531/metadc271861/
Multi-Agent Architecture for Internet Information Extraction and Visualization
Access: Use of this item is restricted to the UNT Community.
The World Wide Web is one of the largest sources of information; more and more applications are being developed daily to make use of this information. This thesis presents a multi-agent architecture that deals with some of the issues related to Internet data extraction. The primary issue addresses the reliable, efficient and quick extraction of data through the use of HTTP performance monitoring agents. A second issue focuses on how to make use of available data to take decisions and alert the user when there is change in data; this is done with the help of user agents that are equipped with a Defeasible reasoning interpreter. An additional issue is the visualization of extracted data; this is done with the aid of VRML visualization agents. The cited issues are discussed using stock portfolio management as an example application. digital.library.unt.edu/ark:/67531/metadc2575/
Multi-Channel Retailing: Function of Consumers' Perceived Benefits and Costs and Retail Synergy
This study investigated the consumers' intention towards multi-channel shopping and the function of synergy in a multi-channel retailing format (i.e., brick-and-mortar stores, catalogs, and the Internet). Two questionnaires were developed, one for the multi-channel consumers and the other for the multi-channel retailers. The structural equation modeling was used to predict the effect of shopping benefits and costs perceived from each channel on the consumer's purchase intention. Data analysis (N = 500) indicated that the purchase intentions were affected by different shopping benefit and cost variables. Qualitative analysis of retailers (N= 10) revealed that the retailers considered synergy to be an important part of their multi-channels. Also, there existed a high level of synergy among the existing three retail channels. digital.library.unt.edu/ark:/67531/metadc4188/
A multi-dimensional entropy model of jazz improvisation for music information retrieval.
Jazz improvisation provides a case context for examining information in music; entropy provides a means for representing music for retrieval. Entropy measures are shown to distinguish between different improvisations on the same theme, thus demonstrating their potential for representing jazz information for analysis and retrieval. The calculated entropy measures are calibrated against human representation by means of a case study of an advanced jazz improvisation course, in which synonyms for "entropy" are frequently used by the instructor. The data sets are examined for insights in music information retrieval, music information behavior, and music representation. digital.library.unt.edu/ark:/67531/metadc4929/

Multi-perspective, Multi-modal Image Registration and Fusion
Multi-modal image fusion is an active research area with many civilian and military applications. Fusion is defined as strategic combination of information collected by various sensors from different locations or different types in order to obtain a better understanding of an observed scene or situation. Fusion of multi-modal images cannot be completed unless these two modalities are spatially aligned. In this research, I consider two important problems. Multi-modal, multi-perspective image registration and decision level fusion of multi-modal images. In particular, LiDAR and visual imagery. Multi-modal image registration is a difficult task due to the different semantic interpretation of features extracted from each modality. This problem is decoupled into three sub-problems. The first step is identification and extraction of common features. The second step is the determination of corresponding points. The third step consists of determining the registration transformation parameters. Traditional registration methods use low level features such as lines and corners. Using these features require an extensive optimization search in order to determine the corresponding points. Many methods use global positioning systems (GPS), and a calibrated camera in order to obtain an initial estimate of the camera parameters. The advantages of our work over the previous works are the following. First, I used high level-features, which significantly reduce the search space for the optimization process. Second, the determination of corresponding points is modeled as an assignment problem between a small numbers of objects. On the other side, fusing LiDAR and visual images is beneficial, due to the different and rich characteristics of both modalities. LiDAR data contain 3D information, while images contain visual information. Developing a fusion technique that uses the characteristics of both modalities is very important. I establish a decision-level fusion technique using manifold models. digital.library.unt.edu/ark:/67531/metadc149562/
The Multi-reference Correlation Consistent Composite Approach: A New Vista In Quantitative Prediction Of Thermochemical And Spectroscopic Properties
The multi-reference correlation consistent composite approach (MR-ccCA) was designed to reproduce the accuracy of more computationally intensive ab initio quantum mechanical methods like MR-ACPF-DK/aug-cc-pCV?Z-DK, albeit at a significantly reduced cost. In this dissertation, the development and applications of the MR-ccCA method and a variant of its single reference equivalent (the relativistic pseudopotential ccCA method) are reported. MR-ccCA is shown to predict the energetic properties of reactive intermediates, excited states species and transition states to within chemical accuracy (i.e. ±1.0 kcal mol 1) of reliable experimental values. The accuracy and versatility of MR-ccCA are also demonstrated in the prediction of the thermochemical and spectroscopic properties (such as atomization energies, enthalpies of formation and adiabatic transition energies of spin-forbidden excited states) of a series of silicon-containing compounds. The thermodynamic and kinetic feasibilities of the oxidative addition of an archetypal arylglycerol ?-aryl ether (?-O-4 linkage) substructure of lignin to Ni, Cu, Pd and Pt transition metal atoms using the efficient relativistic pseudopotential correlation consistent composite approach within an ONIOM framework (rp-ccCA-ONIOM), a multi-level multi-layer QM/QM method formulated to enhance the quantitative predictions of the chemical properties of heavy element-containing systems larger than hitherto attainable, are also reported. digital.library.unt.edu/ark:/67531/metadc103368/
A multi-state political process analysis of the anti-testing movement.
I applied McAdam's political process model for social movement analysis to examine the level of collective resistance to high stakes testing in California, Massachusetts, New York, South Carolina, and Texas from 1985 to 2005. Data on protest occurrences in those states were gathered from online news reports, anti-testing organization websites, and electronic interviews from individuals associated with the anti-testing movement. Variables used in the analysis included each state's key educational accountability legislation, political affiliations of state political leaders, state political leaders' support of accountability issues, student ethnicity profiles, poverty indicators, dropout rates, and collective bargaining laws. I examined the relationship between those variables and protest development in terms of the political process model's three components: framing processes, mobilizing structures, and political opportunity. I concluded California and Massachusetts, with their strong networks of anti-testing organizations, showed more instances of protest than any other state. Slightly fewer protests occurred in New York. Texas showed few instances of anti-testing protests and there were no reports of protests in South Carolina. There was evidence of framing efforts from both proponents and opponents of high-stakes testing, with proponents' framing efforts tending to be more covert. I found that anti-testing protests were primarily initiated by middle-class and affluent groups of citizens, who demonstrated greater political access but whose major concerns differed by state. Evidence showed that although all five states have Republican governors, protests emerged more readily in the three states whose legislatures had a Democratic majority. I found that protest efforts were inhibited when protesters faced serious consequences as a result of their actions. In addition, state political leaders began to take part in the anti-testing protest movement once the state became subject to sanctions under the strict performance requirements imposed by No Child Left Behind. Overall, the political process model proved to be a highly efficient analytical tool in this context. digital.library.unt.edu/ark:/67531/metadc5501/
A Multi-Time Scale Learning Mechanism for Neuromimic Processing
Learning and representing and reasoning about temporal relations, particularly causal relations, is a deep problem in artificial intelligence (AI). Learning such representations in the real world is complicated by the fact that phenomena are subject to multiple time scale influences and may operate with a strange attractor dynamic. This dissertation proposes a new computational learning mechanism, the adaptrode, which, used in a neuromimic processing architecture may help to solve some of these problems. The adaptrode is shown to emulate the dynamics of real biological synapses and represents a significant departure from the classical weighted input scheme of conventional artificial neural networks. Indeed the adaptrode is shown, by analysis of the deep structure of real synapses, to have a strong structural correspondence with the latter in terms of multi-time scale biophysical processes. Simulations of an adaptrode-based neuron and a small network of neurons are shown to have the same learning capabilities as invertebrate animals in classical conditioning. Classical conditioning is considered a fundamental learning task in animals. Furthermore, it is subject to temporal ordering constraints that fulfill the criteria of causal relations in natural systems. It may offer clues to the learning of causal relations and mechanisms for causal reasoning. The adaptrode is shown to solve an advanced problem in classical conditioning that addresses the problem of real world dynamics. A network is able to learn multiple, contrary associations that separate in time domains, that is a long-term memory can co-exist with a short-term contrary memory without destroying the former. This solves the problem of how to deal with meaningful transients while maintaining long-term memories. Possible applications of adaptrode-based neural networks are explored and suggestions for future research are made. digital.library.unt.edu/ark:/67531/metadc278467/
A Multi-Variate Analysis of SMTP Paths and Relays to Restrict Spam and Phishing Attacks in Emails
Access: Use of this item is restricted to the UNT Community.
The classifier discussed in this thesis considers the path traversed by an email (instead of its content) and reputation of the relays, features inaccessible to spammers. Groups of spammers and individual behaviors of a spammer in a given domain were analyzed to yield association patterns, which were then used to identify similar spammers. Unsolicited and phishing emails were successfully isolated from legitimate emails, using analysis results. Spammers and phishers are also categorized into serial spammers/phishers, recent spammers/phishers, prospective spammers/phishers, and suspects. Legitimate emails and trusted domains are classified into socially close (family members, friends), socially distinct (strangers etc), and opt-outs (resolved false positives and false negatives). Overall this classifier resulted in far less false positives when compared to current filters like SpamAssassin, achieving a 98.65% precision, which is well comparable to the precisions achieved by SPF, DNSRBL blacklists. digital.library.unt.edu/ark:/67531/metadc5402/
Multi-year Operation Effect of Geothermal Heat Exchanger on Soil Temperature for Unt Zero Energy Lab
Ground source heat pump (GSHP) uses earth’s heat to heat or cool space. Absorbing heat from earth or rejecting heat to the earth, changes soil’s constant temperature over the multiple years. In this report we have studied about Soil temperature change over multiple years due to Ground loop heat exchanger (GLHE) for Zero Energy Research Laboratory (ZØE) which is located in Discovery Park, University of North Texas, Denton, TX. We did 2D thermal analysis GLHP at particular Depth. For simulation we have used ANSYS workbench for pre-processing and FLUENT ANYS as solver. TAC Vista is software that monitors and controls various systems in ZØE. It also monitors temperature of water inlet/outlet of GLHE. For Monitoring Ground temperatures at various depths we have thermocouples installed till 8ft from earth surface, these temperatures are measured using LabVIEW. From TAC Vista and LabVIEW Reading’s we have studied five parameters in this report using FLUENT ANSYS, they are; (1) Effect of Time on soil Temperature change over Multi-years, (2) Effect of Load on soil temperature change over Multi-years, (3) Effect of Depth on soil temperature change over Multi-years, (4) Effect of Doubling ΔT of inlet and outlet of GLHE on soil temperature change over multi-years and (5) Effect on soil temperature change for same ZØE Laboratory, if it’s in Miami, Florida. For studying effect of time on soil temperature change for multi-years, we have varied heating and cooling seasons. We have four cases they are Case A: GSHP always “ON” (1) 7 months cooling and 5 month cooling and (2) 257 days are cooling and 108 days heating. Case B: GSHP “OFF” for 2 months (1) 7 months cooling and 3 months heating and (2) 6 months cooling and 4 month heating. For Studying Effect of Load on soil temperature change over multi-years, we have considered maximum temperature difference between inlet and outlet for heating and cooling season for simulation. For studying effect of doubling ΔT of inlet and outlet of GLHE, we have doubled the temperature difference between inlet and outlet of GLHP. There will be soil temperature change over year at various depths. For studying Effect of Depth on soil temperature change for multi-years, we have consider 5 depths, they are 4ft, 6ft, 8ft, 110ft and 220ft. The Densities of soil are known from site survey report of ZØE GSHP manufacturers till depth of 13ft. For studying effect of soil temperature over multi-years for same ZØE in Miami, Florida, we have considered equivalent cooling and heating season from weather data for past one year and assuming same number of days of cooling and heating for next 20 years we have simulated for soil temperature change. digital.library.unt.edu/ark:/67531/metadc407847/
Multifractal Analysis of Parabolic Rational Maps
The investigation of the multifractal spectrum of the equilibrium measure for a parabolic rational map with a Lipschitz continuous potential, φ, which satisfies sup φ < P(φ) x∈J(T) is conducted. More specifically, the multifractal spectrum or spectrum of singularities, f(α) is studied. digital.library.unt.edu/ark:/67531/metadc278398/
Multifractal Measures
The purpose of this dissertation is to introduce a natural and unifying multifractal formalism which contains the above mentioned multifractal parameters, and gives interesting results for a large class of natural measures. In Part 2 we introduce the proposed multifractal formalism and study it properties. We also show that this multifractal formalism gives natural and interesting results when applied to (nonrandom) graph directed self-similar measures in Rd and "cookie-cutter" measures in R. In Part 3 we use the multifractal formalism introduced in Part 2 to give a detailed discussion of the multifractal structure of random (and hence, as a special case, non-random) graph directed self-similar measures in R^d. digital.library.unt.edu/ark:/67531/metadc279084/
Multifunctional Organic-Inorganic Hybrid Nanophotonic Devices
The emergence of optical applications, such as lasers, fiber optics, and semiconductor based sources and detectors, has created a drive for smaller and more specialized devices. Nanophotonics is an emerging field of study that encompasses the disciplines of physics, engineering, chemistry, biology, applied sciences and biomedical technology. In particular, nanophotonics explores optical processes on a nanoscale. This dissertation presents nanophotonic applications that incorporate various forms of the organic polymer N-isopropylacrylamide (NIPA) with inorganic semiconductors. This includes the material characterization of NIPA, with such techniques as ellipsometry and dynamic light scattering. Two devices were constructed incorporating the NIPA hydrogel with semiconductors. The first device comprises a PNIPAM-CdTe hybrid material. The PNIPAM is a means for the control of distances between CdTe quantum dots encapsulated within the hydrogel. Controlling the distance between the quantum dots allows for the control of resonant energy transfer between neighboring quantum dots. Whereby, providing a means for controlling the temperature dependent red-shifts in photoluminescent peaks and FWHM. Further, enhancement of photoluminescent due to increased scattering in the medium is shown as a function of temperature. The second device incorporates NIPA into a 2D photonic crystal patterned on GaAs. The refractive index change of the NIPA hydrogel as it undergoes its phase change creates a controllable mechanism for adjusting the transmittance of light frequencies through a linear defect in a photonic crystal. The NIPA infiltrated photonic crystal shows greater shifts in the bandwidth per ºC than any liquid crystal methods. This dissertation demonstrates the versatile uses of hydrogel, as a means of control in nanophotonic devices, and will likely lead to development of other hybrid applications. The development of smaller light based applications will facilitate the need to augment the devices with control mechanism and will play an increasing important role in the future. digital.library.unt.edu/ark:/67531/metadc6108/
A Multimedia Atlas of Dissection for Comparative Anatomy of the Vertebrates
Access: Use of this item is restricted to the UNT Community.
Traditional methods of teaching the laboratory course for Comparative Anatomy of the Vertebrates could be improved by applying current computer technology to construct an interactive, multimedial atlas of dissection. Five specimens used in comparative anatomy courses at most institutions were chosen as representative members of the Phylum Chordata: amphioxus, lamprey, dogfish shark, mud puppy, and cat. Specimens were dissected according to the modified method of Wischnitzer, 1993, and each stage was photographed with a Kodak DC120 digital zoom camera. These images were processed on a Power Macintosh 7600 computer with Adobe Photoshop v. 5.0. The atlas was constructed from these images using Macromedia Authorware v. 4.0.3. Each image contains a series of interactive objects that display a highlight and descriptive text as the cursor passes over each object. digital.library.unt.edu/ark:/67531/metadc2224/

The Multipath Fault-Tolerant Protocol for Routing in Packet-Switched Communication Network
In order to provide improved service quality to applications, networks need to address the need for reliability of data delivery. Reliability can be improved by incorporating fault tolerance into network routing, wherein a set of multiple routes are used for routing between a given source and destination. This thesis proposes a new fault-tolerant protocol, called the Multipath Fault Tolerant Protocol for Routing (MFTPR), to improve the reliability of network routing services. The protocol is based on a multipath discovery algorithm, the Quasi-Shortest Multipath (QSMP), and is designed to work in conjunction with the routing protocol employed by the network. MFTPR improves upon the QSMP algorithm by finding more routes than QSMP, and also provides for maintenance of these routes in the event of failure of network components. In order to evaluate the resilience of a pair of paths to failure, this thesis proposes metrics that evaluate the non-disjointness of a pair of paths and measure the probability of simultaneous failure of these paths. The performance of MFTPR to find alternate routes based on these metrics is analyzed through simulation. digital.library.unt.edu/ark:/67531/metadc4199/
Multiple Activities of Aspartate Transcarbamoylase in Burkholderia cepacia: Requirement for an Active Dihydroorotase for Assembly into the Dodecameric Holoenzyme
The aspartate transcarbamoylase (ATCase) was purified from Burkholderia cepacia 25416. In the course of purification, three different ATCase activities appeared namely dodecameric 550 kDa holoenzyme, and two trimeric ATCases of 140 kDa (consists of 47 kDa PyrB subunits) and 120 kDa (consists of 40 kDa PyrB subunits) each. The 120 kDa PyrB polypeptide arose by specific cleavage of the PyrB polypeptide between Ser74 and Val75 creating an active polypeptide short by 74 amino acids. Both the 40 and 47 kDa polypeptides produced active trimers. To compare the enzyme activity of these trimers, an effector assay using nucleotides was performed. The 140 kDa trimer showed inhibition while the 120 kDa polypeptide showed less inhibition. To verify the composition of the pyrBC holoenzyme complex, B. cepacia dihydroorotase (DHOase, subunit size of 45 kDa) was purified by the pMAL protein fusion and purification system and holoenzyme reconstruction was performed using purified ATCase and DHOase. Both the 140 kDa and the 120 kDa trimers could produce holoenzymes of 550 kDa and 510 kDa, respectively. The reconstructed ATCase holoenzyme from cleaved ATCase showed better reconstruction compared to that from uncleaved ATCase in the conventional ATCase activity gel assay. To characterize the relationship between pyrimidine pathway and virulence factor production, motility tests and biofilm assays were conducted using pyrC- mutant. Even though no significant difference in growth rates was observed, there were significant differences between the wild type and mutant in the production of biofilm and virulence factors. This study will help us to understand the structure and regulation of ATCase holoenzyme with DHOase, and facilitate the use of B. cepacia as an applicable bio-tool. Additionally, we can potentially pursue more efficient drug targets for B. cepacia. digital.library.unt.edu/ark:/67531/metadc33176/
Multiple Measures of the Effectiveness of Public School Montessori Education in the Third Grade
The problem of this study was to measure the effectiveness of a public school Montessori program. The purpose of this study was to measure and compare student academic achievement and self-concept, attendance and promotion rates, and level of parental involvement in the schools of students enrolled in public school Montessori and traditional programs. The 95 subjects in this study were third-grade subjects selected from the student populations in Montessori and traditional school sites. The Iowa Test of Basic Skills (ITBS) was used as the pre-test scores, and the Norm-referenced Assessment Program for Texas (NAPT) was used as the post-test scores to compare academic achievement in reading and mathematics. Multiple regression was used to compare the levels of academic achievement and self-concept. Multiple regression was also used to test for possible relationship between the Montessori and traditional programs and gender and ethnicity. digital.library.unt.edu/ark:/67531/metadc278832/
Multiple Predictors of College Adjustment and Academic Performance for Undergraduates in Their First Semester
College success, as defined by adjustment to college and academic performance, is a multidetermined with a number of contributing influences, including academic factors, personality variables, family characteristics, and environmental factors. This study attempted to provide an organizing model of the college success literature that was based on previous research (e.g., Aspinwall & Taylor, 1994) and current stress-coping theory (Moos & Swindle, 1990). Structural equation modeling analyses indicated that the hypothesized model did not fit the data well. However, subsequent regression analyses did validate the view that college success is multidetermined. Specifically, academic performance was predicted by a combination of academic factors (SAT score and class rank) and academic adjustment. In turn, academic adjustment was predicted by locus of control, perceived social support, and high school class rank. Personal adjustment was predicted by coping strategies employed, parents who fostered autonomy, locus of control, self-esteem, and high school class rank. Finally, social adjustment was predicted by optimism, coping strategies employed, and locus of control. Treatment implications as well as directions for future research were discussed. digital.library.unt.edu/ark:/67531/metadc2778/
Multiple-respondent anecdotal assessments for behavior disorders: An analysis of interrater agreement and correspondence with a functional analysis and treatment outcomes.
An analysis of interrater agreement across multiple respondents on two anecdotal assessments, the Motivation Assessment Scale (MAS) and the Functional Analysis Screening Tool (FAST), was completed for an individual who displayed aggressive behavior. The results of the assessments indicated high agreement across assessments and respondents that the problem behavior was maintained by social positive reinforcement in the form of contingent delivery of tangible items. By contrast, a subsequent experimental analysis indicated that the behavior was maintained by escape from demands. A treatment was implemented based on the functional analysis outcomes to determine if the functional analysis had correctly identified the maintaining variable of the aberrant behavior. Results of the treatment analysis showed significant reductions in the occurrence of aberrant behavior suggesting that the MAS and FAST may not have accurately identified the maintaining variable of the aberrant behavior. digital.library.unt.edu/ark:/67531/metadc5139/
Multiple-Respondent Anecdotal Assessments for Behavior Disorders: An Analysis of Interrater Agreement and Correspondence With Functional Analysis Outcomes
An analysis of interrater agreement across multiple respondents on anecdotal assessments and correspondence between functional analysis outcomes was completed. Experiment I evaluated overall agreement among multiple respondents (direct-care staff) on the hypothesized function of each residents (28 adults with mental retardation) problematic behavior using the Motivational Assessment Scale (MAS) and the Functional Analysis Screening Tool (FAST). Results of the questionnaires indicated that respondents agreed on the function of the problematic behavior for 10 of the 28 residents. Experiment II examined whether, for selected cases in which 4 out of 5 respondents agreed on the function of the problematic behavior, correspondence occurred between functional analyses and anecdotal assessments outcomes. Two of the 6 functional analyses did not evoke the problematic behavior. However, 4 functional analyses did produce corresponding outcomes suggesting that, when the functional analyses produced interpretable data, the results of the functional analyses corresponded with those of the anecdotal assessments. digital.library.unt.edu/ark:/67531/metadc4616/
Multiple-respondent anecdotal assessments for behavior disorders; An analysis of interrater agreement and correspondence with treatment outcomes.
The current study was designed to further evaluate the usefulness of anecdotal assessments. The goal of this study was to evaluate the overall agreement between multiple respondents on the primary function of aberrant behavior using the Motivation Assessment Scale (MAS) and the Functional Analysis Screening Tool (FAST) and, if agreement was obtained, to assess the effectiveness of treatment based on the outcome of the assessments. Results showed that anecdotal assessments were able to identify the general type of contingency maintaining two participants' problem behavior. However, for one participant the assessments did not correctly identify the specific form of reinforcement (attention or tangible items) that maintained the aberrant behavior. digital.library.unt.edu/ark:/67531/metadc3596/
Multiresolution Signal Cross-correlation
Signal Correlation is a digital signal processing technique which has a wide variety of applications, ranging from geophysical exploration to acoustic signal enhancements, or beamforming. This dissertation will consider this technique in an underwater acoustics perspective, but the algorithms illustrated here can be readily applied to other areas. Although beamforming techniques have been studied for the past fifty years, modern beamforming systems still have difficulty in operating in noisy environments, especially in shallow water. digital.library.unt.edu/ark:/67531/metadc277645/

A Multiscalar Analysis of Buruli Ulcer in Ghana: Environmental and Behavioral Factors in Disease Prevalence
Buruli ulcer (BU), an infectious disease caused by Mycobacterium ulcerans, is the third most common mycobacterial disease after leprosy and tuberculosis and a WHO-defined neglected tropical disease. Despite years of research, the mode of transmission of BU remains unknown. This master’s thesis provides an integrated spatial analysis of disease dynamics in Ghana, West Africa, an area of comparatively high BU incidence. Within a case/matched control study design, environmental factors associated with BU infection and spatial behaviors are investigated to uncover possible links between individual daily activity spaces and terrains of risk across disturbed landscapes. This research relies upon archival and field-collected data and analyses conducted with geographical information systems (GIS). digital.library.unt.edu/ark:/67531/metadc115078/
