Mail Order Music: the Hinners Organ Company in the Dakotas, 1879-1936
Founded in 1879 by John L. Hinners, the Hinners Organ Company developed a number of stock models of small mechanical-action instruments that were advertised throughout the Midwest. Operating without outside salesmen, the company was one of the first to conduct all of its affairs by mail, including the financial arrangements, selection of the basic design, and custom alterations where required. Buyers first met a company representative when he arrived by train to set up the crated instrument that had been shipped ahead of him. Tracker organs with hand-operated bellows were easily repaired by local craftsmen, and were suited to an area that, for the most part, lacked electricity. In all, the company constructed nearly three thousand pipe organs during its sixty years of operation. Rapid decline of the firm began in the decade prior to 1936 during which the company sold fewer than one hundred instruments, and closed in that year when John's son Arthur found himself without sufficient financial resources to weather the lengthy depression. The studies of the original-condition Hinners organs in the Dakotas include extensive photographs and measurements, and provide an excellent cross section of the smaller instruments produced by the company. They are loud, excellently crafted, functionally attractive, tonally typical of the early twentieth-century American Romantic organ, and utilize designs and materials typical of this era. Only recently has it been acknowledged that these Hinners organs represent a "meat and potatoes" class of instrument, as it were, an honest meal without the pretense of delicate appetizers, vintage wine, and gourmet dessert. In this way the company offered churches a serviceable and respectable musical alternative to grandeur, and was able to fulfill the needs and meet the budget of a small congregation without the expense of a custom instrument. digital.library.unt.edu/ark:/67531/metadc278307/
Mainstream Success Following Placement in a Modified Type II Setting
The topic of alternative schools is widely available in the literature; however, once a student has been labeled a "troublemaker" and has been placed in a District Alternative Education Program (DAEP), a Type II setting, there is limited information about the overall success of students upon their return to the mainstream. This study compared the success of students formerly placed in a modified disciplinary Type II setting, once they have returned to the mainstream, with their success prior to disciplinary placement. The purpose of the study was to examine if disciplinary measures that remove students from the mainstream environment negatively impact the variables that measure school success, despite legislative mandates such as No Child Left Behind, which advocates success for every student. The population for this study was 86 7th- through 11th-grade students assigned to a DAEP in Texas during the spring of 2003. A comparison of pre- and post-placement dependent variables measuring school success-attendance, passing core courses, behavioral achievement, standardized test score achievement, recidivism, and dropout rates-comprised this study. The independent variables-gender, ethnicity, grade level, socioeconomic status, and disciplinary offense-were used to compare and analyze each dependent variable. The dependent variables of attendance, passing core courses, and behavior demonstrated a decline in the measurement of school success across time. The only dependent variable that demonstrated improvement between the pre- and post-placement periods was achievement on standardized test scores. From the number of students who withdrew from the mainstream during the post-placement semesters, large recidivism and dropout rates were determined, which reflected the large percentage of students who were not successful in the district's mainstream. The comparisons of dependent variables by independent variables resulted in significance only in the analyses of attendance by grade level. This interaction was determined to be significant since p < .05. During both post-placement semesters, 11th-grade attendance increased by 20.2 points. Students in the 7th, 8th, and 9th grades maintained a slight increase in attendance between the pre-placement and first post-placement semester yet experienced an attendance decline in the second post-placement semester. This decline was seen in all three grade levels between the pre-placement and the second post-placement semesters. Attendance among tenth graders declined throughout all semesters of the study. The comparison of attendance by disciplinary offense resulted in a large effect size (eta2). The eta2 reported within 29.8% accuracy in variability when attendance was compared by disciplinary offense. Students placed for assault demonstrated a 27.7 point increase in attendance by the second post-placement semester. Despite the comparison of attendance by the grade level of students being the only significant result, and the comparison of attendance by disciplinary offense resulting in a large effect size, several specific conclusions were drawn from the analyses of the pre- and post-placement data measuring school success. All dependent variable measurements, with the exception of standardized test score achievement, resulted in an overall reduction of mean scores across time. This decline indicates that students do demonstrate a decline in school success following a removal from a mainstream setting. digital.library.unt.edu/ark:/67531/metadc4753/
Maintaining behavior in a child with autism using a previously neutral stimulus, a remote control tactile stimulus, as the consequence
Access: Use of this item is restricted to the UNT Community.
Few studies have investigated methods for establishing neutral stimuli as conditioned reinforcers in human subjects. Conditioned reinforcers, however, can alleviate some of the problems encountered in applied behavior analytic (ABA) therapy for children with autism, such as satiation and suitability of reinforcers for specific environments. A series of reversals evaluated the effects of a conditioning procedure involving pairing a neutral stimulus, the remote control stimulus (RCT), with an identified reinforcer. Phase 1 demonstrated that the RCT was neutral. In Phase 2, alternating pairing and testing conditions were run. During testing the effects of pairing were evaluated by the effectiveness of the RCT in maintaining a response in the absence of a previously available reinforcer (extinction test) and in increasing a new response over a baseline level (learning test). Results from the extinction test suggest that under some pairing conditions the RCT can acquire properties of a reinforcer. digital.library.unt.edu/ark:/67531/metadc2550/

Major Tipping Points in Earth’s Climate System and Consequences for the Insurance Sector Summary
The focus of climate change mitigation policy to date has been on "preventing dangerous anthropogenic interference with Earth's climate system". There is no global agreement or scientific consensus for delineating ‘dangerous’ from ‘acceptable’ climate change but limiting global average temperature rise to 2 °C above pre-industrial levels has emerged as a focus for international and national policymakers. digital.library.unt.edu/ark:/67531/metadc226557/
Major Tipping Points in the Earth’s Climate System and Consequences for the Insurance Sector
A 2°C rise in temperature from pre-industrial levels has been widely regarded as a tipping point for planet earth. Major Tipping Points in Earth's Climate System and Consequences for the Insurance Sector argues instead that sudden volatile transformations in earth's climate will occur long before this 2°C threshold is reached. digital.library.unt.edu/ark:/67531/metadc226687/
Makeshift Information Constructions: Information Flow and Undercover Police
This dissertation presents the social virtual interface (SVI) model, which was born out of a need to develop a viable model of the complex interactions, information flow and information seeking behaviors among undercover officers. The SVI model was created from a combination of various philosophies and models in the literature of information seeking, communication and philosophy. The questions this research paper answers are as follows: 1. Can we make use of models and concepts familiar to or drawn from Information Science to construct a model of undercover police work that effectively represents the large number of entities and relationships? and 2. Will undercover police officers recognize this model as realistic? This study used a descriptive qualitative research method to examine the research questions. An online survey and hard copy survey were distributed to police officers who had worked in an undercover capacity. In addition groups of officers were interviewed about their opinion of the SVI model. The data gathered was analyzed and the model was validated by the results of the survey and interviews. digital.library.unt.edu/ark:/67531/metadc4823/
Making a Good Soldier: a Historical and Quantitative Study of the 15th Texas Infantry, C. S. A.
In late 1861, the Confederate Texas government commissioned Joseph W. Speight to raise an infantry battalion. Speight's Battalion became the Fifteenth Texas Infantry in April 1862, and saw almost no action for the next year as it marched throughout Texas, Arkansas, and the Indian Territory. In May 1863 the regiment was ordered to Louisiana and for the next seven months took an active role against Federal troops in the bayou country. From March to May 1864 the unit helped turn away the Union Red River Campaign. The regiment remained in the trans-Mississippi region until it disbanded in May 1865. The final chapter quantifies age, family status, wealthholdings, and casualties among the regiment's members. digital.library.unt.edu/ark:/67531/metadc278431/

The making of the documentary film Women in Red.
Though the remnants of a stereotype created over two millennia ago still thrive in American popular culture today, redheaded women are enjoying a more positive role in society than they have ever seen before. Women in Red explores the experience of the redheaded woman in America today by examining how the stereotypes have affected a small group of them, how these women relate to the stereotypes, and why, given the verisimilitude of the stereotype, a non-redheaded woman would embrace such an identity with the simple act of dying her hair red. This is the story behind the experience that is Women in Red. digital.library.unt.edu/ark:/67531/metadc9088/

Making Sense of Teaching: A Holistic Approach to Teacher Reflection about Practice
The purpose of this study was to examine the lived experience of reflection and document how a holistic approach to teacher reflection contributes to teachers' understanding of, and improvement in their pedagogical practice. The investigation asked how classroom observations, when followed by a reflective dialogue, impact pedagogical practice. The particular focus included how teachers make sense of observational data during a post-observation, reflective dialogue; how teachers reflect on classroom observational data; and how the holistic reflection experience impacts teachers' pedagogical practice. Three research questions guided this study. How do teachers make sense of observational data during a post observation reflective dialogue? How do teachers reflect on classroom observational data? How might the holistic reflection experience impact teachers' pedagogical practice? Findings from this study provide implications for incorporating the practice of teacher reflection and reflective dialogue as professional development and for educational research. digital.library.unt.edu/ark:/67531/metadc11018/
Making the Connection: How Mentors Choose Protégés in Academic Mentoring Relationships
Among other things, mentoring research is concerned with how mentors go about the process of choosing who they should mentor. Even when mentoring relationships are assigned, mentors need to feel that the efforts they are putting forth are worth the time and energy. What protégé attributes best attract the attention of a mentor? What mentor attributes make some protégés more attractive to them than others? This study looks at 3 explanations for mentor-protégé attraction, shedding light on the mental processes that influence why some protégés find it easy to get mentors and why some have a much tougher time finding the right person to mentor them. Practical and theoretical implications of this study are included. digital.library.unt.edu/ark:/67531/metadc28469/
Maladaptive appraisals and intrusive thoughts associated with obsessive compulsive disorder: A semiidiographic approach.
This project investigated the metacognitive strategies used to appraise obsessive thoughts employed by individuals with different anxiety symptoms. Two hundred eighty-seven undergraduate students completed two repertory grids and three anxiety scales. The repertory grids respectively examined the appraisal process of intrusive thoughts both from the perspective of the rater and the rater's imagined average person. Variables quantified from the rep grid related to the construal process of raters' own intrusions, failed to demonstrate robust differences between OCD, non-OCD anxious, and non-anxious individuals. However, it appears that anxious individuals, not just those with OCD, use metacognitive strategies to suppress rigid constructions under perceived social evaluation. Future studies may wish to use related grid variables to explore the relation between obsessions and social anxiety. digital.library.unt.edu/ark:/67531/metadc4605/
Male Army Nurses: The Impact of the Vietnam War on Their Professional and Personal Lives
As American involvement in Vietnam escalated in the 1960s, the military's need for medical personnel rose as well. A shortage of qualified nurses in the United States coupled with the requirements of providing adequate troops abroad meant increased opportunity for male nurses. To meet the needs of Army personnel, the Army Nurse Corps actively recruited men, a segment of the nursing population that had previously faced daunting restrictions in the Army Nurse Corps (ANC). Amidst mounting tension, the Army Student Nurse Program began accepting men and provided educational funding and support. Additionally, Congress extended commissions in the Regular Army to previously excluded male nurses. Men answered the call and actively took advantage of the new opportunities afforded them by the demands of war. They entered the educational programs and committed to serve their country through the ANC. Once admitted to the corps, a large percentage of male nurses served in Vietnam. Their tours of duty proved invaluable for training in trauma medicine. Further, these men experienced personal and professional growth that they never would have received in the civilian world. They gained confidence in their skills and worked with wounds and diseases seldom seen at home. For many, the opportunities created by the war led to a career in military medicine and meant the chance to seek additional training after nursing school, often specialized training. Relying heavily on oral histories and the archives of the Army Nurse Corps, this study examined the role these nurses played in entrenching men as a vital part of the ANC. digital.library.unt.edu/ark:/67531/metadc2574/
Male-female Perceptions of Male and Female High and Low Achievement Using the Semantic Differential

Male Socialization Experience in Two Birth Cohorts
The purpose of this research was twofold; a quantitative examination of male socialization patterns along with an assessment of change over time in male socialization experiences. Men born in the 1950s and men born in the 1970s were compared to obtain an understanding of male socialization processes and possible changes since feminist issues have become a prevalent source of discourse in society. A survey questionnaire was utilized with a modified snowball sampling technique to explore male socialization experience. One hundred and one men participated in the project. Socialization experience for the men in this sample was five dimensional and while certain dimensions revealed change over time, others remained static. Findings indicate that quantitative measures can be successfully employed to study socialization processes. digital.library.unt.edu/ark:/67531/metadc279402/
Maleic anhydride grafted polypropylene coatings on steel: Adhesion and wear.
Polymeric coatings are being used in a growing number of applications, contributing to protection against weather conditions and localized corrosion, reducing the friction and erosion wear on the substrate. In this study, various polypropylene (PP) coatings were applied onto steel substrates by compression molding. Chemical modification of PP has been performed to increase its adhesion to metallic surfaces by grafting of maleic anhydride (MAH) onto PP in the presence of dicumyl peroxide (DCP). Influence of different concentrations of MAH and DCP on the properties of resulting materials have been examined. The coated steel samples are characterized by scanning electron microscopy (SEM), shear adhesion testing, FTIR and tribometry. The coatings with 3 wt. % MAH have shown the maximum adhesion strength due to maximum amount of grafting. The wear rates increased with increasing the amount of MAH due to simultaneous increase in un-reacted MAH. digital.library.unt.edu/ark:/67531/metadc28452/
Males' Support Toward Females After Sexual Assault
The current study explored the relations among rape myths, attitudes toward rape victims, perceived social support, sex role, and social reactions in a male undergraduate sample (N = 205). Males who have provided support to a sexual assault victim were compared to those who have not provided support to a sexual assault victim on several measures. Social reactions of those who have provided support to a sexual assault victim were compared to hypothetical reactions provided by individuals who have not previously provided support. Results indicated that rape related attitudes and beliefs did not differ between those who have and have not provided support to a sexual assault victim. In addition, individuals who were responding to a hypothetical situation reported that they would provide more positive social support than individuals who were responding to an actual situation. Implications for clinical work and future research in this area are discussed. digital.library.unt.edu/ark:/67531/metadc3625/
Mama D's 2 Blocks: A Documentary Film
Mama D's 2 Blocks tells the story of a neighborhood home in New Orleans that was transformed into a distribution center and used to assist residents impacted by Hurricane Katrina's devastation in 2005. Mama D stayed at her home throughout the storm and remained there until the floodwaters had subsided. After the water had drained, socially minded youth from all over the country were drawn to Mama D's home and stayed there while supporting local renewal efforts. The film documents their joining together, without electricity or running water, and assisting in the rebuilding process undertaken by Mama D and other neighborhood residents. This film captures a community in action, how it survived, and the first steps taken towards the rebuilding of New Orleans. digital.library.unt.edu/ark:/67531/metadc3674/

Management Tools for Prescribed Burning for Tallgrass Prairie Restoration at the Lewisville Lake Environmental Learning Area
The Lewisville Lake Environmental Learning Area (LLELA) is a wildlife management area with tallgrass prairie, an endangered ecosystem. Essential ecosystem processes, especially fire, are part of restoration. To support fire management efforts at LLELA and surrounding areas, this project evaluated and developed tools for fire restoration. The four primary prairie grasses respond favorably to burning. Fuel loads and fuel models vary by scale and survey method. One- and 10-hour fuel moisture can be predicted using a statistical model; 100- and 1,000-hour fuel moisture cannot. Historic weather data suggests that burning can occur when it is most effective. The production of ozone precursors produced by burning is comparable to those emitted every six minutes by regional automobiles. digital.library.unt.edu/ark:/67531/metadc4405/

Managerial self-awareness and its impact on leadership in high-performing managers.
Managerial self-awareness is thought to impact leadership. A multi-rater feedback instrument was used to gather performance data on 70 managers in a large multi-national airline in regards to five leadership dimensions: making sound decisions, driving for results, effective communication, self-management, and innovation. Difference scores between self and direct reports were calculated and used as the operational definition of managerial self-awareness. T-tests were run to examine the difference between high performers and average performers. No significant differences were found. Additionally, correlational measures between the five leadership competencies and the managerial self-awareness measure indicated statistically weak relationships. digital.library.unt.edu/ark:/67531/metadc3102/
Managing Cattail (Typha latifolia) Growth in Wetland Systems
Nutrient availability, water depth, competition, and soil management effects on cattail (Typha latifolia) growth in wetland systems were examined. Soluble reactive phosphorous (SRP), nitrate-nitrogen (NO3-N), and ammonia-nitrogen (NH3-N) removals were tested at a constructed wetland receiving municipal wastewater effluent. Over all, no significant differences in nutrients occurred between diverse planted and cattail areas. T. latifolia seeds, under the canopy of Eleochoris macrostachya, had low seed germination. Established stands of emergent vegetation can prevent cattail colonization and spread. Germination of T. latifolia at various water depths was tested, and depth impacts on cattail seedling growth and survival were ascertained using various moist soil management techniques in three ponds. Water levels at 0cm and >40cm can adversely impact cattail establishment. digital.library.unt.edu/ark:/67531/metadc3210/

Managing HIV: Self-Efficacy, Mindfulness, Optimism, and Meaning
The purpose of the current study is to investigate the extent to which mindfulness (observing and describing), dispositional optimism and personal meaning are associated with self-efficacy for managing a chronic disease (SEMCD) among 57 people living with HIV in the DFW Metroplex. Several statistical analyses, including a hierarchical linear regression analysis, were conducted. Results indicate, after controlling for age and gender, the overall model accounted for a significant proportion of the variance (adjusted R2 = .39) in self-efficacy for managing chronic disease, F (6, 50) = 5.80, p < .01. Both subscales of mindfulness were significantly related to self-efficacy. However, observing was negatively, associated with SEMCD (β = -0.44, p < .05), and describing was positively associated with self-efficacy (β = 0.60, p < .01). As a result, incorporating these mindfulness skills into self-efficacy based self-management programs may greatly improve self-management, thus positively influencing psychological and physiological health outcomes that are essential to the health and wellbeing of people living with HIV/AIDS. Future research should investigate methods of manipulating observing and describing, and determine what proficiency in these skills is most beneficial to improve self-efficacy. digital.library.unt.edu/ark:/67531/metadc84252/

Manipulating Sucrose Proton Symporters to Understand Phloem Loading
Phloem vascular tissues transport sugars synthesized by photosynthesis in mature leaves by a process called phloem loading in source tissues and unloading in sink tissues. Phloem loading in source leaves is catalyzed by Suc/H+ symporters (SUTs) which are energized by proton motive force. In Arabidopsis the principal and perhaps exclusive SUT catalyzing phloem loading is AtSUC2. In mutant plants harboring a T-DNA insertion in each of the functional SUT-family members, only Atsuc2 mutants demonstrate overtly debilitated phloem transport. Analysis of a mutant allele (Atsuc2-4) of AtSUC2 with a T-DNA insertion in the second intron showed severely stunted phenotype similar to previously analyzed Atsuc2 null alleles. However unlike previous alleles Atsuc2-4 produced viable seeds. Analysis of phloem specific promoters showed that promoter expression was regulated by Suc concentration. Unlike AtSUC2p, heterologous promoter CoYMVp was not repressed under high Suc conc. Further analysis was conducted using CoYMVp to test the capacity of diverse clades in SUT-gene family for transferring Suc in planta in Atsuc2 - / - mutant background. AtSUC1 and ZmSUT1 from maize complemented Atsuc2 mutant plants to the highest level compared to all other transporters. Over-expression of the above SUTs in phloem showed enhanced Suc loading and transport, but against expectations, plants were stunted. The implications of SUT over-expression to enhance phloem transport and loading are discussed and how it induces a perception of phosphate imbalance is presented. digital.library.unt.edu/ark:/67531/metadc283792/

Manuel M. Ponce: A critical study of his Concierto Romántico for piano and orchestra.
The Concierto Romántico for Piano and Orchestra is one of Manuel M. Ponce's outstanding compositional accomplishments from his Romantic period, reflecting both the state of Mexican music at the turn of the 20th century, and his early nationalist tendencies. However, it remains the only concerto in Ponce's output in need of a more comprehensive analysis. This treatise focuses on a global investigative that examines descriptive and analytic references to the work, as well as a comparison and clarification of the existing score sources. An analytical and stylistic musical study using conventional theoretical techniques leads to a musicological interpretation of the work's extra-musical meaning, based on close assessments of Ponce's compositional practice and social principles. digital.library.unt.edu/ark:/67531/metadc3909/

The Map and the Territory in the Poetry of Wallace Stevens
In this dissertation, Wallace Stevens' imagination-reality problem as depicted in his poetry is discussed in terms of an eco-critical map-territory divide. Stevens's metaphor of "the necessary angel" acts to mediate human necessity, the map, with natural necessity, the territory, in order to retain contact with changing cultural and environmental conditions. At stake in this mediation are individual freedom and the pertinence of the imagination to the experience of reality. In Chapter 2, the attempt at reconciliation of these two necessities will be described in terms of surrealism. Stevens's particular approach to surrealism emphasizes separating and delineating natural necessity from human necessity so that through the poem the reader can experience the miracle of their reconciliation. In Chapter 3, this delineation of the two necessities, map and territory, will be examined against Modernist "decreation," which is the stripping bare of human perception for the purpose of regaining glimpses of the first idea of the external world. And in Chapter 4, Stevens's approach to the problem of the map-territory divide will be considered against his alienation or internal exile: balancing nature and identity through mediating fictions results in a compromised approach to the marriage of mind and culture in a historically situated place. digital.library.unt.edu/ark:/67531/metadc12205/
Map-based cloning of the NIP gene in model legume Medicago truncatula.
Large amounts of industrial fertilizers are used to maximize crop yields. Unfortunately, they are not completely consumed by plants; consequently, this leads to soil pollution and negative effects on aquatic systems. An alternative to industrial fertilizers can be found in legume plants that provide a nitrogen source that is not harmful for the environment. Legume plants, through their symbiosis with soil bacteria called rhizobia, are able to reduce atmospheric nitrogen into ammonia, a biological nitrogen source. Establishment of the symbiosis requires communication on the molecular level between the two symbionts, which leads to changes on the cellular level and ultimately results in nitrogen-fixing nodule development. Inside the nodules hypoxic environment, the bacterial enzyme nitrogenase reduces atmospheric nitrogen to ammonia. Medicago truncatula is the model legume plant that is used to study symbiosis with mycorrhiza and with the bacteria Sinorhizobium meliloti. The focus of this work is the M. truncatula nodulation mutant nip (numerous infections and polyphenolics). The NIP gene plays a role in the formation and differentiation of nodules, and development of lateral roots. Studying this mutant will contribute knowledge to understanding the plant response to infection and how the invasion by rhizobia is regulated. Previous genetic mapping placed NIP at the top of linkage group 1 of the M. truncatula genome. A NIP mapping population was established with the purpose of performing fine mapping in the region containing NIP. DNA from two M. truncatula ecotypes A17 and A20 can be distinguished through polymorphisms. Positional mapping of the NIP gene is based on the A17/A20 genetic map of M. truncatula. The NIP mapping population of 2277 plants was scored for their nodulation phenotype and genotyped with flanking molecular genetic markers 146o17 and 23c16d, which are located ~1.5 cM apart and on either side of NIP. This resulted in the identification of 170 recombinant plants, These plants' DNAs were tested further with different available genetic markers located in the region of interest, to narrow the genetic interval that contains the NIP gene. Segregation data from genotyping analysis of recombinant plants placed NIP in the region between 4L4 and 807 genetic markers. digital.library.unt.edu/ark:/67531/metadc3638/
Mapping the Southwest: Final Performance Report
This report documents the Mapping the Southwest project, led by the University of North Texas (UNT) and with their partner, the University of Texas at Arlington (UTA) Libraries Special Collections. The project was supported by a grant from the National Endowment for the Humanities (NEH). This final report briefly describes the Mapping the Southwest project activities and accomplishments in six work areas, and provides a discussion of achievements, issues faced and resolved, and lessons learned that may be of benefit to others. Additional detail is provided in some areas with appendices. digital.library.unt.edu/ark:/67531/metadc179681/
