The Distribution of Pathogenic Pseudomonas aeruginosa in Sewage: The purpose of this study was to extend our understanding of the ecological relationships of P. aeruginosa by investigating the differences or similarities between the strains of this organism found in sewage and those found as pathogens in human infections. This research was approached by comparing the serological types of P. aeruginosa isolated from sewage contaminated waters in Argentina (South America) to those isolated from sewage contaminated waters in Texas. They were typed with sera obtained using P. aeruginosa isolated from human infections. The data obtained revealed that bacteria isolated from sewage in Texas and from soil and water in Argentina are antigenically similar to those isolated from human infections.
Distribution of Phosphates in a Sewage Plant and its Receiving Waters: The purpose of this paper is to detail the distribution and quantity of soluble phosphates in an activated sludge plant, its discharge creek, and receiving reservoir. The resultant analyses and comparison of data should provide some better understanding of the fate of phosphorus in a Southwestern waterway system.
The Distribution of Prepositions in English Adverbial Phrases: This thesis describes the rules of prepositions in English adverbial phrases.
Distribution, Size, Condition, and Food Habits of Selected Fishes in a Reservoir Receiving Heated Effluent from a Power Plant: This study was undertaken in order to provide further insight into the effects of artificial heating on the fisheries of a small reservoir in the Southwest. The following specific objectives were established: (1) to map the reservoir for the distribution of heated water, (2) to determine the distribution of selected species of sports, rough, and forage fish in areas affected by the effluent and in areas not affected, (3) to compare size and condition of selected species of fish from areas affected by the effluent to size and condition of fish from areas not affected, and (4) to compare food habits of channel catfish in areas affected by the effluent to the food habits of channel catfish in areas not affected.
A Distributive Education Display Manual: The problem of this investigation is to prepare a merchandise display manual that can be used by the teacher-coordinator, students of distributive education, other trainees, training sponsors, and salespeople.
District Leadership Supporting PLC Implementation in a Rapid Growth District: A growing body of work has emerged regarding the responsibilities required of district leaders in establishing plans that initiate and create conditions for sustainability of continuous improvement achieved through a systemic reform structure such as professional learning communities. However, limited research exists in respect to sustaining cultures of continuous improvement in rapid growth districts. Rapid growth districts can be described as school systems, which construct and open multiple campuses annually. The underlying premise of this study considered how humans interact with one another within a rapidly changing professional organization. Change theory, professional capital, organizational learning theory, and system reform emerge as the conceptual framework in this study of district support of professional learning communities. Data collection for this qualitative descriptive case study included interviewing six K-12 principals, administering the PLCA-DS survey to 247 K-12 staff members, and document review. Recognition of the importance of the PLC framework, building capacity, development of collaborative culture, and issues resulting from constant change due to rapid growth were the four themes generated by the participants to support continuous improvement in a rapid growth district. The four themes combined with the components of the conceptual framework outline how district leaders in a rapidly changing environment cultivate a process leading to system-wide improvement.
District Support: Strategies for Building Capacity in Elementary Principals in a Rapid Growth District: The purpose of this descriptive case study was to examine the role of the central office staff and the strategies used to support capacity building in elementary principals in a rapid growth district. By synthesizing research and models from education reform scholars, the conceptual framework of professional capital, intrinsic motivation, the educational change process, and professional learning communities was generated to advance the understanding of utilizing PLCs as a foundation for central office to initiate and sustain continuous improvement in a rapid growth district. The Professional Learning Community Assessment - District Support developed by Olivier, Huffman, and Cowan was administered to 126 participants within the curriculum and instruction department and three elementary schools to collect data to analyze the five dimensions of PLCs within the school district. Eleven interviews were conducted with members of the curriculum and instruction department and elementary principals. According to the eleven interviewees, and PLCA-DS, six themes emerged to support the role of capacity building in elementary principals using the PLC model as a framework. The PLC infrastructure, supportive central office, collaborative culture, continuous improvement, differentiated opportunities to learn, and data use were the six themes generated by the participants to support continuous improvement in elementary principals. Each of the five PLC dimensions were visible throughout the themes as the findings illustrated six key practices currently in motion within the rapid growth school district used to build capacity in elementary principals.
District Systematic Supports of an Instructional Coaching Program: The purpose of this qualitative study was to identify the systems, structures, and behaviors district leaders employ and enact to assist elementary school principals' relationship with their school instructional coach. Through the synthesis of current research, the conceptual framework was developed with a focus on district leadership behaviors and instructional coaching programs. The conceptual framework consisted of professional capital theory, instructional coaching model, and principal leadership skills. This study assessed the perceptions of six instructional coaches, six elementary principals, and three district leaders from Comet ISD regarding the specific behaviors district leaders use to support the relationship between the school principal and instructional coach. The three-part data collection process included document analysis, face-to-face interviews, and focus group interviews to support the triangulation of data. Through the a priori coding process, four themes emerged that identified key district structures and leadership behaviors needed to support the relationship between the school principal and instructional coach: program clarity, principal leadership skills, professional learning opportunities, and culture of continuous learning. This study revealed a specific need to understand program implementation, accountability, and evaluation of the effectiveness of the instructional coaching program in a fast-growth district.
Disturbing Nature's Beauty: Environmental Aesthetics in a New Ecological Paradigm: An ecological paradigm shift from the "balance of nature" to the "flux of nature" will change the way we aesthetically appreciate nature if we adopt scientific cognitivism-the view that aesthetic appreciation of nature must be informed by scientific knowledge. Aesthetic judgments are subjective, though we talk about aesthetic qualities as if they were objectively inherent in objects, events, or environments. Aesthetic judgments regarding nature are correct insofar as they are part of a community consensus regarding the currently dominant scientific paradigm. Ecological science is grounded in metaphors: nature is a divine order, a machine, an organism, a community, or a cybernetic system. These metaphors stimulate and guide scientific practice, but do not exist independent of a conceptual framework. They are at most useful fictions in terms of how they reflect the values underlying a paradigm. Contemporary ecology is a science driven more by aesthetic than metaphysical considerations. I review concepts in the history of nature aesthetics such as the picturesque, the sublime, disinterestedness, and formalism. I propose an analogy: just as knowledge of art history and theory should inform aesthetic appreciation of art, knowledge of natural history and ecological theory should inform aesthetic appreciation of nature. The "framing problem," is the problem that natural environments are not discrete objects, so knowing what to focus on in an environment is difficult. The "fusion problem" is the problem of how to fuse the sensory aspect of aesthetic appreciation with highly theoretical scientific knowledge. I resolve these two problems by defending a normative version of the theory-laden observation thesis. Positive aesthetics is the view that insofar as nature is untouched by humans, it is always beautiful and never ugly. I defend an amended and updated version of positive aesthetics that is consistent with the central elements of contemporary ecology, and emphasize the heuristic, …
Disturbing the Peace: Disturbing the Peace is a short, 16mm sync-sound fiction film. Alone one stormy night, a woman must contend with an intruder breaking into her home. The intruder turns out to be a teenage boy. He claims to have broken in only to retrieve a family heirloom he hid there when he and his parents lived in the same house years ago. When the boy finds the heirloom, the woman begins to believe his story, and soon realizes he doesn't have a good home life. The boy asks permission to stay until the storm breaks. She agrees. Should the boy be trusted, or is he telling one lie after another? The police arrive to witness the outcome of the story.
The Diurnal Variation of Cosmic Radiation: The primary purpose of this investigation was to study the diurnal variation of cosmic-ray intensity.
Diverging Perceptions of Emotional Black and White Female Leaders: Stereotypical beliefs about emotion have been shown to influence perceptions of competence. While emotional White women are often presumed to be generally less competent, emotional Black women receive variable competence ratings due to the intersecting stereotypes concerning both their race and gender. However, it is unclear how perceptions of competence fluctuate in response to anger, a stereotypically male emotion, in comparison to sadness, a stereotypically female emotion. The project at hand utilized participants' responses to a scenario of White and Black leaders engaging with subordinates in their workplace expressing either neutral, angry, or sad responses to an interaction. We aimed to identify if a Black woman leader's expression of anger garnered a more favorable response than a White woman leader's expression of anger in addition to whether both leader's expression of sadness would garner similarly low ratings of competence. Results reveal that perceptions of a woman leader's competence can be influenced by race alone with no significant influence from emotional expression. Specifically, a Black woman leader's competence can on average be rated lower than a White woman's competence regardless of emotional expression. This study provides further evidence that group stereotypes manifest differentially based on context.
Diverse Learners in the Classroom: Students with Special Needs Enrolled in Science, Technology, Engineering, and Mathematics (STEM) Texas Public Classrooms: The purpose of this study was to determine if students with special needs participating in an inclusive classroom can learn the skills related to a STEM career as compared to the general student population. The study involved seventh grade students from two rural middle schools in north central Texas and was framed through a constructivist lens using a quasi-experimental design with a convenience sample. The Solenoid Invention Kit Assessment and the STEM Semantics Survey used in this study were used from a previously large existing dataset from a grant funded by the National Science Foundation for Innovative Technology Experiences for Students and Teachers. Findings suggested that there were no significant differences between the general student population and students with special needs. However, STEM coursework in an inclusive classroom may impact students' decision to pursue STEM careers.
Diversity, Equity, and Inclusive Behaviors of School Librarians: Perceptions during Times of Crisis: School librarians create an atmosphere where learners feel empowered. Moreover, school library programming should support diversity, equity, and inclusive learning opportunities to facilitate student success. Thus, school librarians are expected to model and advocate for equitable learning spaces while considering the universal design for learning approach to improving accessibility, utilization, and relevance for all library patrons. Although it has been established that school library standards support diversity, equity, and inclusion (DEI), more is needed to know about the impact of a crisis on school library programming and services. In addition, extensive research has not been conducted to determine school librarians' responsiveness and strategies to provide services for their school communities during disruptive times. This study examines school librarians' perceptions of the opportunities and challenges encountered while endeavoring to engage in DEI practices during crises.
Diversity Revealed: Photovoice Methodology as a Means for Understanding How Teens Construct Diversity: Through the partnership of standpoint theory and photovoice method, the present study looked at how teenagers, attending a multicultural education camp, define diversity, as well as what the participants considered to be the benefits and limitations of diversity. Standpoint theory gives the theoretical perspective to understand the marginalized voice of teenagers, while photovoice provides the tools to better capture and understand their marginalized voice. This study was situated in a professionally-developed camp, Camp CommUNITY, that emphasizes multicultural awareness amongst teens. Nine participants and 46 pictures were analyzed. Resulting from open coding, 11 categories and 6 themes were identified. Each theme and definitions of diversity are approached with a dialectical perspective, yielding to the model of dialectical dimensions of diversity. To answer Research Question 2, participants identified both benefits and limitations for photovoice method. Additional theoretical, practical, and methodological implications, limitations, and directions for future research are addressed.
Diversity Without Inclusion: The Experience of Female Graduate Students of Color at a Minority Serving Institution: Graduate education can be psychologically taxing, and the academic tasks that graduate students are required to perform can cause a great level of stress, insecurity, and uncertainty. The unique experiences that female students of color face at the intersections of gender, race, and class may have negative effects on their academic performance and attainment. This research explored the experiences of discrimination among the female African American/Black and Hispanic/Latina graduate students and their coping strategies to survive in the program of study at the University of North Texas (UNT), as a minority serving institution (MSI). A narrative research method was applied and 13 in-depth interviews were conducted using a semi-structured interview protocol. The findings showed the participants experienced various types of intragroup and intergroup discrimination based on the intersections of their multiple identities, especially race, gender, and socioeconomic status. The findings of this study revealed structural discrimination that participants experienced through their education; starting with their low income neighborhood where they were raised and the discrimination at the university. They perceived that minorities are not represented in the management and faculty positions, and there is an inadequacy of support resources and lack of racially sensitive advising services for female graduate students of color. The findings of this research showed that a large majority of the participants perceived UNT as an institution with diversity but without inclusion. They had used two strategies to respond to the incidents of discrimination; building resilience to fulfil a purpose, and self-care and building support system. This research concludes that UNT is in need to create a climate that is more accessible, caring, and supportive for female graduate students of color. Implications for practice and policy are discussed.
Divided-Tenure, Divided Recovery: How Policy and Land Tenure Shape Disaster Recovery for Mobile Homeowners: People who live in mobile homes have heightened vulnerability to disasters, due in part to mobile homes increasingly occupying high-hazard risk lands and the precarious ownership status known as divided-tenure. Divided-tenure is when an individual owns a mobile home and rents the land underneath. To identify the challenges associated with divided-tenure and disaster recovery from a policy perspective, this study analyzed the content of key HUD policies and performed a comparative policy analysis of purchase opportunity laws (requirements of landowners to give mobile homeowners an opportunity to purchase the property their home resides on) in three states: California, Florida, and New York. Content analysis indicated few direct references to mobile homes. Inconsistencies and confusing messaging were found in the existing federal guidance. The lack of consistent terminology and guidance on addressing divided-tenure, limits mobile homeowner's options for disaster recovery, including eligibility for federal disaster aid and potentially participation in relocation or buyout programs. The three selected states' purchase opportunity laws reviewed in this study were rated as weak. Policies lacked alignment with federal documents and opportunities for mobile homeowners were difficult to navigate. A pathway to land ownership could give mobile homeowners more control over their disaster recovery options, but current laws still limit that ability. This study and future work have the potential to help mobile homeowners, an understudied yet growing population, experience a more equitable disaster recovery, which currently is lacking, based on the reviewed federal and state policies.
Divine and the Everyday Devil (Short Stories): Divine and the Everyday Devil contains a scholarly preface that discusses the experiences and literary works that influenced the author's writing with special attention in regards to spirituality and sexuality. The preface is followed by six original short stories. "Evil" is a work addressing a modern conception of evil. "Eschatology" concerns a man facing his own mortality. "The Gospel of Peter" tells the story of a husband grappling with his wife's religious beliefs. "The Mechanics of Projects" relates the experiences of a woman looking for love in Mexico. "The Rocky Normal Show" involves a husband growing apart from his wife and "Mutant: An Origin Story" is about a teenager trying to find his own unique identity.
The Divine Comedy as a Source for the Poetry of T. S. Eliot: In spite of the large amount of criticism written about T. S. Eliot, no attempt has been made to point out the great debt that Eliot owes to Dante Alighieri, and the pervasive influence of The Divine Comedy on Eliot's poetical works. This thesis endeavors to illustrate the extent of that debt and influence.
The Divine Coming of the Light: The Divine Coming of the Light is a memoir-in-essays that covers an experience, from 2007 to 2010, when I lived in Kosuge Village (population 900), nestled in the mountains of central Japan. I was the only foreigner there. My memoir uses these three years as a frame to investigate how landscape affects identity. The book profiles who I was before Japan (an evangelical and then wilderness guide), why I became obsessed with mountains, and the fall-out from mountain obsession to a humanistic outlook. The path my narrator takes is one of a mountain hike. I was born in tabletop-flat West Texas to conservative, Christian parents in the second most Republican county by votes in America. At 19, I made my first backpacking trip to the San Juan Mountains of western Colorado and was awed by their outer-planetary-like massiveness. However, two friends and I became lost in the wilderness for three days without cell phones. During this time, an obsession possessed me as we found our way back through the peaks to safety, a realization that I could die out there, yes, but amid previously unknown splendor. I developed an addiction to mountains that weakened my religious faith. Like the Romantic poets before me, God transferred from the sky to the immense landscape. I jettisoned my beliefs and became an outdoor wilderness instructor. On every peak I traveled up, I hoped to recreate that first conversion experience when I was lost in the woods. After college, while teaching English in Kosuge Village, I learned about the mountain-worshipping religion Shugendo: a mixture of Buddhism, Shintoism, and Shamanism. I climbed dozens of peaks, spending several days backpacking. However, while in Japan, I was nearly fatally injured on a solo, month-long hike. I saw the accident as a warning and turned my attention to …
The Divine Pilgrimage of Conrad Aiken: A Study of his Poetic Quest for Personal Identity: Because his search for self is such a dominant and important theme of his work and because it grows out of a rich tradition in western thought, it is the purpose of this thesis to examine this search and to clarify Aiken's ideas concerning the self and the methods and form he used to communicate these ideas.
Divisibility in Abelian Groups: This thesis describes properties of Abelian groups, and develops a study of the properties of divisibility in Abelian groups.
Dmitri Shostakovich and the Fugues of Op. 87: A Bach Bicentennial Tribute: In 1950-51, for the bicentennial of the death of J. S. Bach, Dmitri Shostakovich wrote his collection of Twenty-four Preludes and Fugues, Op. 87. This thesis is a study of the fugal technique of Shostakovich as observed in Op. 87, in light of the fugal style of Bach as observed in The Well-Tempered Clavier, Volume One. Individual analyses of each of the twenty-four Shostakovich pieces yield the conclusion that Op. 87 is an emulation of Bachian fugal methods as observed in The Well-Tempered Clavier, Volume One.
DNA Degradation as an Indicator of Post-Mortem Interval: The question of post-mortem interval (PMI) or time since death is often the most sought after piece of information associated with a medical death investigation. Based on the observation that DNA degradation disproportionately affects the analysis of larger genetic loci, it was proposed that DNA degradation, as a result of autolysis or putrefaction, could prove suitable as a potential rate-of-change indicator of PMI. Nine randomly amplified polymorphic DNA (RAPD) analysis primers and three sets of directed amplification primers were evaluated to determine their suitability for use in assessing the degree of DNA fragmentation in tissue samples. They were assessed for amplicon specificity, total DNA target sensitivity, allele monomorphism and the observance of degradation-based profile changes. Markers meeting the requisite criteria were then used to assess a range samples degraded under controlled and uncontrolled conditions. Tissue samples collected from seven domestic pigs (Sus scrofa) were incubated under controlled laboratory or uncontrolled field conditions to produce samples simulating those potentially collected in a forensic case. DNA samples isolated from these specimens were then analyzed at those loci which had been determined to meet the requisite criteria. Collectively, data generated from these analyses indicate that genetic profiles generated by this approach can provide information useful for estimating the post-mortem interval, with the locus and amplicons used being most useful during the first 72 hours after death.
DNA-DNA Hybridization of Methane Oxidizing Bacteria: Bacteria classified in the family Methylomonadaceae must derive their carbon from one-carbon compounds. They are characterized by the possession of internal membranes of two types. Type I membranes are layered and fill the middle of the cells while type II membranes form concentric layers around the periphery of the cells. Also, there are two metabolic pathways by which the methylobacteria assimilate one-carbon compounds. Further evidence of this dichotomy was sought by DNA-DNA saturation hybridization of DNAs from both types of methylobacteria. Very low DNA-DNA homology was seen between types I and II or within the types. It was not possible, therefore, to correlate the degree of genetic relatedness with either the nature of the internal membranes or the pathway of carbon assimilation.
Dna Profiling of Captive Roseate Spoonbill (Ajaia Ajaja) Populations As a Mechanism of Determining Lineage in Colonial Nesting Birds.: Roseate spoonbills are colonial nesting birds with breeding grounds extending from the United States Gulf coast to the pampas of Argentina. The U.S. population suffered a severe bottleneck from 1890 to 1920. The population's recovery was slow and partially credited to migrations from Mexican rookeries, but a gene pool reduction would be expected. Five polymorphic Spoonbill autosomal short tandem repeat (STR) loci [three (GAT)n, one (AAAG)n and one (GT)n] and one Z/W-linked microsatellite exhibiting sex-specific dimorphism were isolated and characterized. The Z/W-linked STR locus accurately confirmed the sex of each bird. Allelic profiles for 51 spoonbills obtained from Dallas (Texas), Fort Worth (Texas) and Sedgwick County (Kansas) zoos revealed a non-continuous distribution of allele frequencies, consistent with the effects of a population bottleneck. Allelic frequencies also differed significantly between the isolated zoo populations. Although extra-pair copulations were suspected and difficult to document, zoos commonly used observational studies of mating pairs to determine familial relationships among adults and offspring. STR parentage analysis of recorded family relationships excluded one or both parents in 10/25 cases studied and it was further possible to identify alternative likely parents in each case. Mistaken familial relationships quickly lead to the loss of genetic variability in captive populations. Here, a decreased heterozygosity (HO) in 2nd generation captive-bred birds was observed at 3 out of 4 loci evaluated. Although these results could not be statistically validated because of the small number of individuals available for study (15 wild birds with no offspring vs. eight 2nd generation captive birds), they are considered biologically important, as decreased HO is an indicator of inbreeding and this apparent decrease occurred within two generations of removal from the wild. Collectively, the evidence obtained from this study suggests that captive spoonbill populations are experiencing rapid loss of diversity from an already depleted wild gene …
DNA Typing of HLA-B by PCR with Primer Mixes Utilizing Sequence-Specific Primers: The aim of this study was to design a resolution typing system for the HLA-B gene. This technique involves a one-step PCR reaction utilizing genomic DNA and sequence-specific primers to determine the specificity of each allele and to produce a larger primer data base ideal for serological analysis. The application of this technique to serological analysis can improve serology detection which is currently hindered by antibody cross-reactivity and the unavailability of useful typing reagents.
Do American Adults Know How to Exercise for a Health Benefit?: Approximately 950,000 Americans die annually from cardiovascular disease. Physical activity is a major risk factor for the development of CVD and a risk factor for stroke. The purpose of this research was to determine whether American adults know how to exercise to achieve health benefits and whether this knowledge is a function of demographics. Items included knowledge of exercise guidelines and knowledge of traditional and non-traditional exercise activities. This information was obtained from 22 questions that were a part of a larger national survey of 2,002 American households. Statistical analyses of this sample, indicate American adults have knowledge which varies by demographic groups. Data revealed that overall the 61+, Less than High School, African-American, Hispanic-American, and Male groups have the least amount of knowledge about exercise. These data can provide health educators with important aspects of exercise knowledge for future health promotions/interventions.
Do As They Say, and As They Do: An Integrated Approach to the Study of Norm Influence on Truth Commission Initiation, 1976-2003: Truth commissions are bodies established in political transition, and they have the stated purpose of reckoning with human rights abuses committed by members of former regimes. The question driving this research is "Why have truth commissions increased so rapidly in the last 20 years?" This study moves beyond current research, which suggests that particular domestic political circumstances alone determine choice of transitional justice mechanisms. I argue that an international rule of behavior, the transitional restorative norm, has emerged and spread to decision-makers in countries of transition. In support of this notion, I perform a pre-theoretical historical analysis of transitional justice and develop a theory of decision-making in transition-which is later tested with quantitative statistics. This integrated approach allows for increased scientific rigor in the examination of international norms. Ultimately, the study demonstrates an interrelationship between shared ideas and political environments in the determination of domestic policy.
Do Banks' Dividends Signal Their Financial Health?: This paper examines the relation between banks' dividends and their future financial health. Using banks' Nonperforming Loans Ratio, Loan Loss Provision Ratio, and Z-score as proxies for their financial health, I show that there is a strong positive relation between banks' dividends lagged by one quarter and their financial health in the current quarter. This main finding continues to hold following several additional tests, including the application of an instrumental variable approach, the use of change in dividends as the key independent variable, the exclusion of banks that are subject to stress test, the addition of macroeconomic variables, the exclusion of too-big-to-fail banks, and the exclusion of non-depository banks. I also find that the positive relation between banks' dividends and their future financial health is more pronounced for banks with a higher degree of opacity, a lower Tier 1 capital ratio, and during the 2007-2009 financial crisis. This paper contributes to three strands of the finance literature, including the Risk Reduction Hypothesis of dividend signaling in corporate finance, bank dividend policies, and the determinants of banks' financial stability. First, I show that there is a positive relation between banks' dividends lagged by one quarter and their financial health in the current quarter, also meaning that banks' dividends are negatively associated with their future risk conditions. This finding is consistent with the Risk Reduction Hypothesis regarding dividend signaling. Second, Floyd, Li, and Skinner (2015) propose a new idea that banks use dividends to signal financial health, and they rely on this idea to explain why banks have a higher and more stable propensity to pay dividends vis-à-vis industrials during the past several decades. My finding that banks' dividends are positively associated with their future financial health empirically supports this idea proposed by Floyd, Li, and Skinner (2015). Last, to my knowledge, …
Do College Students with ADHD have Expressive Writing Difficulties as Do Children with ADHD?: This study analyzed the expressive writing of college students. Twenty-two ADHD students and 22 controls were asked to write a story based on a picture story and a personal challenge. The texts were compared based on several qualitative and quantitative parameters. The results show that students in both groups presented similar text quality. Out of six qualitative parameters only one was statistically different between the two groups: ADHD students performed worse in adequacy, but only in the picture task. Students writings were also investigated using corpus based analysis. This analysis showed that ADHD students used less unusually frequent words in the picture story but more in the challenge task. Taken together the findings indicate no significant difference in expressive writing between ADHD and non ADHD college students. An explanation to this result is that college students with ADHD may have passed the filter of prior education.
Do contingency-conflicting elements drop out of equivalence classes? Re-testing Sidman's (2000) theory: Sidman's (2000) theory of stimulus equivalence states that all positive elements in a reinforcement contingency enter an equivalence class. The theory also states that if an element from an equivalence class conflicts with a programmed reinforcement contingency, the conflicting element will drop out of the equivalence class. Minster et al. (2006) found evidence suggesting that a conflicting element does not drop out of an equivalence class. In an effort to explain maintained accuracy on programmed reinforcement contingencies, the authors seem to suggest that participants will behave in accordance with a particular partitioning of the equivalence class which continues to include the conflicting element. This hypothesis seems to explain their data well, but their particular procedures are not a good test of the notion of "dropping out" due to the pre-establishment of equivalence classes before the conflicting member entered the class. The current experiment first developed unpartitioned equivalence classes and only later exposed participants to reinforcement contingencies that conflicted with pre-established equivalence classes. The results are consistent with the notion that a partition developed such that the conflicting element had dropped out of certain subclasses of the original equivalence class. The notion of a partitioning of an equivalence class seems to provide a fuller description of the phenomenon Sidman (1994, 2000) described as "dropping out" of an equivalence class.
Do Different Political Regime Types Use Foreign Aid Differently to Improve Human Development?: Existing literature on foreign aid does not indicate what type of political regime is best to achieve human development outcomes or use aid funds more efficiently. I contend that political leaders of different regime types have personal incentives that motivate them to utilize foreign aid to reflect their interests in providing more or less basic social services for their citizens. Using a data set of 126 aid-recipient countries between the years of 1990 and 2007, I employ fixed effects estimation to test the model. The overall results of this research indicate that foreign aid and democratic institutionalization have a positive effect on total enrollment in primary education, while political regime types show little difference from one another in providing public health and education for their citizens.
Do Minutes Matter? Connecting Tardiness to Academic Achievement: Within the scope of all that is expected to be accomplished in education, what difference does a tardy make? This study was designed to examine the significance of tardiness, as it relates to student achievement, as measured by the results of the state math test. It also investigated the generation of change by the campus administrator to improve punctuality, with a new method of enforcing the tardy policy with the use of an electronic data system. This study used archived data from the one high school in a suburban school district in Texas. From a student population of 2,631, two subject groups of 919 and 1,310 were determined. Spearman rho results confirmed a moderate inverse relationship between student tardiness and results on the state math test. Descriptive discriminant analysis indicated that tardiness contributed to 25% of the variance in the results on the state math test, when considered alone, and had a smaller contribution when considered with other variables. A visual review of the data portrayed an inverse relationship between the occurrences of tardiness and the pass/fail results on the state math test; as tardiness increased, passing rates decreased. Wilcoxon signed rank test results revealed a reduction in the magnitude of tardiness with the implementation of a new method of enforcing the tardy policy. Tardiness does impact academic achievement, as affirmed in this study. Also, the campus administrator can implement changes that improve punctuality. This study signified that the phenomenon of tardiness should be given greater consideration as a factor impacting both cognitive and non-cognitive development and endorsed that minutes do matter.
Do Non-Native Grammars Allow Verbs to Raise to Agreement?: The purpose of this thesis is to determine whether the setting of the verb movement parameter in L2 is dependent on agreement acquisition. The Optionality hypothesis (Eubank, 1994) is tested by examining the L2 grammar of Chinese learners of English. To test this hypothesis, the sentence matching procedure originally described in Freedman and Forster (1985) is used. It is found that no current theory truly accounts for the results that are obtained.
Do Not Eat Fish from These Waters and Other Stories: Earl suffers from a guilty obsession with a monster catfish. Eddie Klomp searches dog tracks for the ghosts of his lost childhood. Mike Towns is a hopeless blues musician who loses everything he cares for. Blair Evans learns to love a pesky wart. Americana becomes confused with the difference between knowledge and sex. Do Not Eat Fish from These Waters And Other Stories is a collection of short stories that explores the strange and often defeated lives of these Southern characters (and one from the point-of-view of a feral hog). Each man, woman, and hog flails through a period of potential metamorphosis trying to find some sort of meaning and worth in the past, present and future. Not all of these characters succeed.
Do Predictions of Professional Business Economists Conform to the Rational Expectations Hypothesis?: Tests on a Set of Survey Data: A set of forecast survey data is analyzed in this paper for properties consistent with the Rational Expectations Hypothesis. Standard statistical tests for "rational expectations" are employed utilizing consensus forecasts generated by an interest rate newsletter. Four selected variables (Fed Funds rate, M1 rate of growth, rate of change in CPI, and real GNP growth rate) are analyzed over multiple time horizons. Results tend to reject "rational expectations" for most variables and time horizons. Forecasts are more likely to meet "rationality" criteria the shorter the forecast horizon, with the notable exception of forecasts of real GNP growth.
Do Re Mi? Yes! Using Music and Visual Arts to Promote Thai Children's English Vocabulary Development: This research examines the efficacy, if any, of the Music and Visual Arts (MVA) program in improving the English vocabulary development of first grade Thai students. The researcher developed the Vocabulary Recognition Assessment (VRA) as a measure of English vocabulary development. It employs the accuracy and rapidity method of word recognition as a measurement of English language development in Thai children. Forty first grade Thai students in a Bangkok elementary school participated in the study. Participants were divided equally between an experimental group and a control group. During a nine-week period, students in the experimental group were instructed with the MVA strategy, while students in the control group were taught with the Visual Arts (VA) strategy. Paired sample t-test, ANOVA, and ANCOVA were used to analyze data from the VRA, to compare the pre-test and the post-test in terms of accuracy scores and rapidity scores of the control group and the experimental group. Data revealed that students instructed with the MVA strategy improved their English vocabulary development in terms of accuracy of word recognition significantly more than students taught English using the VA strategy. No significant difference was found between the MVA strategy and the VA strategy in terms of rapidity of word recognition. The MVA strategy could be a useful strategy for Thai early childhood teachers to use in helping Thai children learn English vocabulary.
Do Shared S-minus Functions Among Stimuli Lead to Equivalence?: We examined the claim that equivalence classes contain all positive elements in a reinforcement contingency by asking whether negative stimuli in a reinforcement contingency will also form an equivalence class, based on their shared function as S-minus stimuli. In Experiment 1, 5 subjects were tested for equivalence for positive and negative stimuli. Testing of positive stimuli preceded testing of negative stimuli. Two of five subjects demonstrated equivalence for positive stimuli, and three subjects demonstrated equivalence for negative stimuli. In Experiment 2, order of testing was reversed. Four of six subjects demonstrated equivalence for positive stimuli, and none demonstrated equivalence for negative stimuli. In Experiment 3, positive and negative stimuli were tested together. Only one of five subject demonstrated equivalence for positive and negative stimuli. These data suggest that negative stimuli may enter an equivalence class, and so Sidman paradigm should be expanded. Order of testing was found as a meaningful variable.
Do You Know the Storm?: The Forgotten Lieder of Franz Schreker: Franz Schreker (1878-1934) was a Jewish-Austrian composer of great success during the first decades of the twentieth century. Schreker’s reputation diminished after 1933 when Hitler came to power and, in 1938, his compositions were labeled Entartete Musik (“degenerate music”) by the Nazis in a public display in Düsseldorf. The Third Reich and post-war Germany saw Schreker as a decadent outcast, misunderstanding his unique style that combined elements of romanticism, expressionism, impressionism, symbolism, and atonality. This study of Schreker’s Lieder will pursue two goals. First, it will analyze the Mutterlieder (before 1898), the Fünf Gesänge (1909), and the first piece from Vom ewigen Leben (1923) stylistically. Schreker composed nearly four dozen Lieder, incorporating a wide range of styles and ideas. By studying and performing these songs written at various points in his career (including early songs, songs written after he met Schoenberg, and his last songs during the height of his fame), I hope to develop a clearer understanding of how Schreker synthesized the many cultural forces and artistic movements that seem to have influenced his compositional style. Second, this study will consider the sociopolitical circumstances that fueled the disintegration of his reputation. This disintegration occurred not just during the Third Reich, but also afterwards, notably in an often discussed essay by Theodor Adorno. Only in the last thirty years have scholarly voices critical of such rejections of Schreker emerged. My ultimate goal, then, is to join this reevaluation, studying and contextualizing this repertory to develop a new understanding of an oft-neglected chapter in the history of the German Lied.
"Do You Remember?": Remembering Gay Victims of the Holocaust Through Jake Heggie's Theater Piece, For a Look or a Touch: American composer Jake Heggie's For a Look or a Touch exists as the only classical music work of remembrance based on the topic of remembering homosexual victims of the Holocaust. The composer, after being approached by Mina Miller, wrote this 2007 composition as part of the Music of Remembrance concert series. The music of this work varies in style from a blazing swing dance to a haunting vocalise on "oo." Gene Scheer created the text, delivered in the work by the characters Manfred Lewin and Gad Beck, as a compilation of many influential stories from the documentary film Paragraph 175. For a Look or a Touch chronicles the horrendous treatment of homosexuals before, during, and after World War II. Chapters include an introduction to homosexual persecution during Hitler's reign, a look at current works of remembrance and how For a Look or a Touch came to fruition, an explanation of the texts created by Gene Scheer, a discussion on Jake Heggie's musical setting of this text, and avenues for possible future research. Appendices include text of the German anti-sodomy laws as written in Paragraph 175, the mission statement for the organization Music of Remembrance, transcripts from personal interviews with both Jake Heggie and Gene Scheer, correspondence with Heggie, and the source delineation of Gene Scheer's text.
"Doble Identidad": Doble Identidad conveys my experience as someone who struggles with their cultural identity. Through the expository modes of self-reflexivity, participatory, experimental, and poetics, the film displays the factors that molded my cultural identity. My childhood memories and interactions with my loved ones help me tell the story of how my cultural identity has and continues to leave me with feelings of inadequacy of not being Mexican or American enough.
"Doce Canciones Mexicanas": A Singer's Guide to Manuel M. Ponce's (1882-1948) Romantic Mexican Art Song as Described in His Essay "La Canción Mexicana": The underrepresentation of Mexican art song has left classical singers with few Spanish-language repertoire options. Currently, the music of Spain dominates this scene and Mexican art song has yet to earn a place in academic curricula and concert halls. Manuel María Ponce (1882-1948) retains an important position in Mexican music. However, Ponce's vocal repertoire—consisting of over 150 songs—remained dormant for many decades after his death due to its misclassification by music aristocrats in Mexico that greatly affected their diffusion. Consequently, few copies were published during Ponce's life, making them difficult to find. The need in the singing community for repertoire of this kind has raised many questions not only about its existence and availability, but also about its origins and relationship to the established Art Song canon. To promote the diffusion of this underrepresented repertoire, a style analysis of Ponce's Romantic Mexican Art Song is offered through the lens of his writings about Mexican Song. The analysis includes vital information about the origins, form, style, and subjects of these songs. Tangible examples of these traits are provided from Ponce's Doce Canciones Mexicanas along with historically-informed suggestions for singers and translations of the text with IPA transcriptions.
Doctoral Level Counseling Students’ Experiences and Perceptions of Learning in a Cohort Environment: Learning community literature supports the use of student cohorts to enhance learning through increased peer interaction and common course work. Researchers employed the qualitative method of phenomenography to identify various ways doctoral counseling students conceptualize and experience learning in a cohort over the course of a single academic year. Participants were all 10 members of a single southwestern U.S. university counseling program doctoral cohort of full-time students between 20 and 59 years of age with 5 members 20-29, 4 members 30-39, 1 member 50-59; 8 female, 2 male; 9 White non-Hispanic, 1 African-American. Data were transcripts from 30 one-hour interviews, three for each participant over the course of their first year of study. The research team that analyzed the data consisted of three advanced counseling program doctoral students, each with research methods coursework. Results revealed nine dynamic structural aspects of learning: dialogue, diversity, knowledge, motivation, support, shared experience, relationship development, interpersonal awareness, and conflict. Findings support the use of learning communities in doctoral level counselor education programs. Cohort members demonstrated increasing awareness of the potential learning benefits of cohort interaction and developed more in depth strategies over time to utilize the cohort to enhance learning. Future counselor educators may now with greater confidence design learning communities and curriculum to facilitate doctoral cohort development for optimal student interaction.
The Doctoral Program in Higher Education at North Texas State University: An Appraisal: Doctoral graduates of the program in Higher Education, Division of Higher Education, North Texas State University, from the fall of 1969 through spring, 1973, were selected as subjects for an evaluation of the program. To appraise the effectiveness of the program, the evaluation attempted to: (1) determine how the graduates viewed various aspects of their doctoral program and experiences at North Texas State University; (2) appraise the effectiveness of the doctoral program in Higher Education in light of the career goals and needs of the graduates and how the program served those needs; (3) present conclusions and recommendations based on the findings of the study which could aid in the administration of the program, provide information for planning new programs and policies, or in supporting those already in existence. A questionnaire was developed and used as the data-gathering instrument, after being revised according to suggestions given by a jury. The questionnaire was mailed to graduates on August 17, 1973, and a follow-up letter was mailed on September 19, 1973, to those non-respondents who could be identified. Of the total number of graduates who received the questionnaire, 69 (71 per cent) responded. Data contained in the questionnaires were numerically coded and recorded on keypunch worksheets. With the aid of the staff from the N.T.S.U. Computing Center, print-outs were produced from the worksheets which contained tabulated data. Tables were made from the data for analysis and interpretation. Analysis of the data led to the following conclusions. The program is producing graduates who have a marketable education with most of them teaching in four-year colleges and universities. The emphases on college teaching and administration are major strengths of the program and graduates rate a strong degree of satisfaction with the major program components, structure and curriculum. Competencies gained in educational research and statistics …

Document and Information Experience in Virtual Zenanas: An Exploration of a Diaspora Small World: The word diaspora is currently understood as the large scale voluntary movement of people, along with capital and goods due to the mechanisms of globalization. Adopting a diaspora, gender and leisure perspective, this dissertation looked at the information and document experiences of a particular fan community of women belonging to the Indian diaspora and the online spaces created and occupied by them (fan fiction blogs which can be viewed as book clubs). The study also looked at memory making and documenting of the same as a part of document experience, resulting in what can be termed as "serendipitous memory archives." The blogs hosting fan fiction and the mediated practices they support were viewed as documents for the study. The online spaces were conceptualized as small worlds and the theoretical framework used for the study consisted of a preliminary model of a small world (based on literature review and my understanding of the world under study), information experience as a concept as well as document experience models. The results show that social ties play a big role in the information and document experience, while memory making and documenting of the same are also seen to happen as part of the document experience. The results also show that adopting a document perspective enables us to see the myriad ways in which information is experienced, freeing us from considering as information only that which helps us in meeting a purpose or which fills a gap. Implications and suggestions for future research are discussed.
Documentary Film: Access Denied: Sculptor Eric McGehearty incorporates dyslexia, a learning disability, into his artwork to express his challenges with his limited ability to recognize and understand the written word. The film Access Denied focuses on Eric and his disability. Recognized in 1896, dyslexia has been studied and researched by scientists and educators. New assistive technology is now available to aid dyslexics in reading and writing. Specialized schools provide techniques to improve student learning. However, some options are not readily available to the general public; therefore, information about how to deal with the disability is not easily accessed. The aims of this documentary are to raise awareness of available resources to assist with learning as well as to demonstrate a relationship between art and dyslexia.
Documentary Film: Accidental Shakespeare: According to the American Heritage College Dictionary, the word “community” derives from the Latin roots: communitas and communis meaning “fellowship” and “common,” respectively. The word “amateur” derives from the Latin roots: amator meaning “lover.” A community of amateurs, who love to put on plays, exists within the Denton Community Theatre. Their first attempt at classical theatre was the January 2006 production of Romeo and Juliet, directed by Brad Speck. The film follows two actors (through observational shooting) - Kevin Wickersham, a waiter who is trying theatre for the first time, and Jeffrey Johnson, a theatre college student trying Shakespeare for the first time - as they relate to a process and community that is new to them.
Documentary Film: I Named Her Angel: Recent political developments in the world show us that different cultures need to know and understand each other better. Even though technological developments like the Internet, satellites, cable television and conglomeration of big media entities have made mass communication more effective and faster, we cannot easily say that these developments help to bring world cultures together. As a result, mass audiences are not very much able to see what few productions do speak to these issues in a constructive manner. The main aim of this documentary film project is to serve as a small step towards helping different cultures to understand each other better. This documentary film conveys the basics of Mevlevism by following the formal gatherings of a Mevlevi den in Istanbul, Turkey. A den or tekke is a place where Islamic people gather and perform their religious activities. During these gatherings they do the sema, they pray, they listen to music, and they discuss spiritual matters. Sema is the entire ritual they perform as part of their ceremonies including listening to music, singing and chanting to attain a state of religious emotion and ecstasy or vecd. The documentary film is structured around a twelve year old girl, Elif, who is learning the basics of Mevlevism. The interviews conducted with regulars from the den explain to the audience why people are attracted to this belief system. Filming the ceremonies at the 550-year-old Mevlevi temple in Galata, Istanbul accentuates the historic background of this belief system. The Night of Reunion is the day in which Mevlevis celebrate the passing of Mevlana Celaleddin Rumi, the founder of Mevlevism and provides the climax of the film. Elif performs on that night, a very important moment in her spiritual life.
