Development Of A Workflow For The Comparison Of Classification Techniques, Zanifa Omary

Dissertations

As the interest in machine learning and data mining springs up, the problem of how to assess learning algorithms and compare classifiers become more pressing. This has been associated with the lack of comprehensive and complete workflow depending on the project scale to provide guidance to its users. This means the success or failure of the project can be highly dependent on the person or team carrying it.

The standard practice adopted by many researchers and experimenters has been to follow steps or phases from existing workflows such as CRISP-DM, KDD and SASSEMMA. However, as machine learning and data mining …

The Role Of Teachers In School Safety, Leslie Lee Brown

Dissertations

This study examined teachers' perceptions of their abilities to effectively respond to crises on their school campuses. Teachers were surveyed in numerous southeastern states in contrasting demographic areas. Much of the literature addressed acts of violence, natural disasters, and threats of terrorism in schools. Past literature designates urban areas as places where violence has been a more prevalent element of everyday life. Current evidence shows that school shootings and natural disasters can occur anywhere. This shows that planning, practicing, and preparing for crises events are imperative no matter the demographic area in which a school is located. However, there is …

A Metamorphosis Of Thought: Parent Education Based On Transformative Learning Theory In A Title I-Funded Middle School, Ayanna Lichelle Shivers

Dissertations

Section 1118(e)(2) of the No Child Left Behind Act of 2001 encouraged public schools to conduct and evaluate parent education programs to assist with closing the achievement gap. In an effort to combat the existing problem, the researcher engaged in a mixed-methods study to address four research questions.

A comparative-quantitative study, using the Middle School Parent Perception Survey, was conducted to determine if there were statistically significant differences in perceptions of parents whose children attended Title I funded and non-Title l-funded schools in the following areas—barriers to parent involvement, their ability to assist their children with schoolwork, and the support …

This document sought to bring clarity and focus to sacred music through limitation, as well as causing sacred music composers to make changes in their compositional methods. While still being modern, music had to conform to certain rules and regulations in order to be functional within the Catholic liturgy. The document also provided a great deal of detailed information regarding day-to-day occurrences within …

Islamism, State Control Over Religion And Social Identity: Turkey And Egypt, Alper Y. Dede

Dissertations

In post Cold War politics, as a powerful alternative to the authoritarian "status-quo" regimes of the Muslim World, Islamism has become among the most critical political issues as various Islamist movements increasingly challenge governments for more political reforms, democratization, and greater participation and in the political process.

The current debates on Islamism, though useful, often emphasize the issues of security, democracy, or stability. However, they seem to overlook the importance of processes and the mechanisms of Islamism as well as how Islamists' concerns for preserving their Islamic social identity (Muslimness) and government control over religion contribute to their politicization. Thus, …

Dissertations

Five decades of English-only orthodoxy in American public schools came to an end with the passage of the Bilingual Education Act of 1968 (BEA). This research investigates how the convergence of community activism, ethnic pride, and union clout shaped and reshaped bilingual education programming at thelocal level within the broader context of post-WWII American society. By comparing and contrasting the experiences of communities in Texas and Michigan with the newly enacted BEA, this study illuminates the changing political culture of school governance from the high-water mark of Johnson-era liberalism tothe surging tide of Reaganite conservatism. It asserts that the tradition …

Sustainability Evaluation: Development And Validation Of An Evaluation Checklist, Daniela C. Schroeter

Dissertations

Sustainability permeates many levels of human activity. Interest in sustainability is grounded primarily in the sustainable development field which is concerned with the survival of humans on planet earth, and with the growing demands of meeting people's long-term needs. In the North American evaluation literature, however, sustainability is primarily thought of in terms of continuing program activity beyond initial funding cycles via diversification of funding streams or institutionalization.

Two distinct perspectives for evaluating sustainability were identified. The first is concerned with micro-level issues related to the continuation of programs, policies, and other types of human action. The second is a …

The Latino population, the largest ethnic minority in the United States, is a diverse group originating from numerous geographic regions of Latin America. Latinos vary in the risk for type 2 diabetes, a condition that exacts a costly burden on those who suffer with it. With the Latino population diversity, diverse strategies are needed. One strategy is to improve outcomes of life quality by improving knowledge of those who deliver health services to Latinos with type 2 diabetes. Through measurement of quality of life (QOL), the more precious aspects of living, how one feels about living with diabetes, can be …

Physical Education Content Knowledge And Physical Activity Behaviors Of Mississippi High School Students, Christina Leigh Lumpkin Martin

Dissertations

The present study investigated physical education content knowledge, physical activity behaviors, and body mass indexes of 386 Mississippi ninth (n=236 ) and twelfth (n=150) grade students with a goal of establishing evidence-based needs to modify physical education curricula. Results of this study suggested that a significant, direct relationship did exist in the Assessment of Sub-disciplinary Knowledge in Physical Education: Exercise Physiology (ASK PE: EXP);(Ayers, 2004) scores and scores from the Modifiable Activity Questionnaire for Adolescents (M4<2^4);(Aaron & Kriska, 1997) for both ninth and twelfth grade students. Findings also suggested that physical education content knowledge (exercise physiology) is more likely to contribute to twelfth grade reported physical activity scores than ninth grade reported physical activity scores. However, ninth graders were more active than twelfth graders. This is possibly explained by the small difference (5%) in ASK PE: EXP scores between ninth (M ASK PE: EXP score = 52%, SD=.22) and twelfth graders (M ASKPE: EXP score = 57%, SD = .21). As a whole, results indicated that Mississippi ninth and twelfth grade students' average ASKPE: EXP score was lower (M = 53%, SD = .22) than students in 16 other states (M = 62%, SD = 7.65). Further, majority of Mississippi high school students are performing significantly below the established, research-based cutoff score of 62% (observed N below 62% = 236 and observed N above 62% = 150). This is notable, because findings also suggested that students who scored higher (M knowledge = 76%, SD = .08);(M activity = 8.6 hours/week, SD = 9.7) or above 62% on the ASK PE: EXP were more likely to be active during a weekly basis compared to those who scored lower (M knowledge = 39%, SD = .14);(M activity = 5.8 hours/week, SD = 9.8) or below a 62% on the ASK PE: EXP. With this noted, it was recommended that Mississippi high schools evaluate the current physical education programs, and strive to implement curricula that can provide students with the necessary knowledge and skills to make lifelong healthy decisions.

Health Anxiety And Cognition: Chronic Awareness Of Health Concerns Or Situational Activation Of Latent Dysfunctional Assumptions About Illness?, Desmon Craig Mitchell

Dissertations

Rationale: This study investigated if health anxious individuals have chronically aroused illness-related concerns or if these concerns remain latent, only to be activated when first primed by illness-related stimuli. To test these alternatives this study examined whether participants, with varying levels of health anxiety, differed as to their (a) performance on an emotional Stroop task that included health-related words, (b) memory tasks (free recall and recognition tasks), and (c) the participants' dream content, after either being exposed, or not exposed, to an illness-related trigger. Hypotheses: If illness concerns are chronically activated in health anxious individuals, then participants will perform worse …

Treatment Of A Wife's Body In The Fiction Of Indian Sub-Continental Muslim Women Writers, Hafiza Nilofar Khan

Dissertations

Ismat Chughtai of India, Tehmina Durrani of Pakistan, and Selina Hossain of Bangladesh depict some of the sociological, religious and legal aspects of wife abuse that is a chronic, yet little discussed anathema in a Sub-Continental Muslim wife's life. "Treatment of the Wife's Body in the Fiction of Indian Sub-Continental Muslim Women Writers," examines the fiction and autobiographical works of these women writers who problematize the deeply ingrained traditional modes of domestic violence as perpetuated upon the minds and bodies of Sub-Continental Muslim wives. Chughtai, Hossain and Durrani identify culture specific practices such as child marriage, dowry, polygamy, honor crimes, …

Exploring The Cognitive Underpinnings Of Word Retrieval Deficits In Dyslexia Using The Tip-Of-The-Tongue Paradigm, Sarah Margaret Hanly

Dissertations

Over the past thirty years a consensus has emerged that the word reading difficulties of dyslexic readers stem from deficits in phonological processing. One experimental paradigm that has provided support for this view is the finding that dyslexic readers demonstrate deficits in word retrieval from long term memory on picture naming tasks. Dyslexic readers are able to retrieve fewer words in their receptive vocabularies and are less accurate than normally developing readers. However, the conclusion that dyslexic readers? difficulties in picture naming are the consequence of deficits in phonological processing is inferential. The current study uses the tip-of-the-tongue (TOT) paradigm …

The Impact Of Gender Socialization On Women?S Learned Technological Helplessness And Its Andragogical Implications, Joy Elise Harris

Dissertations

This research investigated a proposed construct of learned technological helplessness (LTH) in female adult learners, which is believed to be impacted by socialization into traditional gender roles, teacher modeling, and age. A two-pronged approach was used to examine women?s attitudes and beliefs about their abilities to use technology as a learning and personal productivity tool. Participants were females, over age 18, on two campuses of a public Midwest research university. Prior to the primary research, a pilot study (n=204) was undertaken for the purpose of creating a teacher modeling instrument, which measured how teachers model the use of technology. The …

Does Institutional Capacity Matter? A Case Study Of The Zambian Forestry Department., Rosemary Fumpa Makano

Dissertations

Understanding why some organizations are more effective in their service delivery than others is a central discourse in both public administration and political organization. Scholars and practitioners all agree that the defining factor is institutional (state) capacity. Since the mid-1980s, deforestation in Zambia has been on the rise, especially in Protected Forest Areas, suggesting poor management by the Forestry Department, an institution mandated to manage these public lands. Ironically, despite the strategic position that forests hold in sustaining both the daily subsistence needs of over 90% of the Zambian population as well as the as the numerous industries that depend …

Spatial And Temporal Dynamics Of Lekking Behavior And Female Mate Choice In The Blue-Crowned Manakin (Lepidothrix Coronata, Aves: Pipridae), Renata Duraes Ribeiro

Dissertations

In lekking species, males aggregate at display grounds (?leks?) that females visit to copulate. Lekking systems are non-resource-based and males vary widely in reproductive output. This dissertation investigates how spatial and temporal factors influence lekking dynamics and female mate choice in the blue-crowned manakin Lepidothrix coronata. The first chapter deals with spatial dynamics of lekking behavior, and investigates whether leks are formed by the establishment of males on sites of high female density (?hotspot hypothesis?). Predictive maps of female spatial distribution were built based on field data and contrasted to the lek distribution. Leks were located in sites where males …

The Detection Of Malingering On Measures Of Competency To Stand Trial: A Study Of Coached And Uncoached Simulators, Rachael Elizabeth Springman

Dissertations

Competency to stand trial evaluations serve as the most frequently requested type of forensic evaluation. Despite the court?s need for accurate and credible information, defendants referred for competency evaluations may be motivated to malinger incompetency in order to avoid trial and gain personal liberty (Rogers, Sewell, Grandjean, & Vitacco, 2002). Furthermore, motivated malingerers can obtain information about tests prior to evaluations, particularly from the Internet and their attorneys. Previous research has demonstrated that coaching on test-taking strategies helps malingerers avoid detection on psychological tests like the MMPI-2 (e.g., Storm & Graham, 2000), but no research has examined the effects of …

Mechanistic Studies Of Specific Dna Cleavage By Pvuii Restriction Endonuclease, Xie Fuqian

Dissertations

PvuII restriction endonuclease is a homodimeric protein which recognizes and cleaves the palindromic sequence (CAG?CTG) in the presence of Mg(II) ions. Starting with PvuII as a model system, pKa calculations with crystallographically defined metal ligated water are applied to PD?D/ExK motif metallonucleases in order to investigate the activation of nucleophile in metal dependent DNA hydrolysis. These results establish the electrostatic contributions of the metal ions and the conserved Lys in lowering water pKa. The calculated pKa values of metal ligands have been used to simulate the pH dependence of Mg(II) binding to PvuII. The bell shaped pH-rate profile is dissected …

Academic Writing And The Pedagogical Practices Of Effective Teachers, Thomas Devere Wolsey Edd

Dissertations

Composition, particularly when academic register is required, is a complex task. Because cognitive flexibility theory explains how humans can spontaneously restructure knowledge and adapt to situational demands, it is ideally suited to the ill-structured domain of transactional writing. Global aspects related to paragraph and whole-text structure and local operations related to word and sentence-level features define academic writing. A mixed-methods design used quantitative methods for investigation of five corpora of 10th grade students' work. Qualitative methods were used to explore the means teachers used in promoting academic writing and the interactions they intended to promote via teaching cues, including prompts. …

The purpose of this study was to describe the relationships among symptom experience, symptom management, and symptom outcome based on spiritual well-being. A quantitative, descriptive, correlational, and noninterventional study design, …

Transformations With Tai Chi: The Experience Of Community-Dwelling Tai Chi Practitioners, Sunny Yim Alperson Phd

Dissertations

While Tai Chi practice has dramatically increased across the U.S., its mechanism is unknown, and overall understanding of the phenomenon is lacking. The purpose of this study was to explore the experience of community-dwelling Tai Chi practitioners through a qualitative study, detailing its social and personal appeal, the reasons for their continued involvement, its symbolic meanings, and its impact on their lives. Utilizing the grounded theory method and dimensional analysis, in-depth interview data from 23 practitioners, aged 49-82 were audio-recorded, transcribed, coded and analyzed to derive a grounded theory. A theoretical model, transformation with moving meditation was developed, reflecting the …

A Qualitative Study Of Buddhist Informed Psychotherapists, Michael Sean Harris

Dissertations

The field of psychology has a history of distancing itself, if not outright dismissing, both religion and spirituality. In recent years, however, psychology has come to move more toward an embrace of religious and spiritual experience. Buddhism, often expressed as a philosophical system without regard to theistic or nontheistic underpinnings, has been integrated with psychological theory in recent scholarly literature. This dissertation is an exploratory study regarding howBuddhist psychological perspectives are applied in actual psychotherapeutic practice. A participant pool of ten psychotherapists who self-identified as utilizing Buddhism in their work was studied along a variety of dimensions. Demographic questionnaires, audiotaped …

Intimacy, Elizabeth Knapp

Dissertations

In one of his finest poems, "Asphodel, That Greeny Flower," William Carlos Williams writes: "It is difficult / to get the news from poems / but men die miserably everyday / for lack / of what is found there." Earlier, his contemporary, W.H. Auden, had made his famous claim that "poetry makes nothing happen." While the views of the two great modernists appear to be at odds with each other, they are in fact two sides of the same argument, the yin and yang at the center of all true art. For what these poets saw as critical to both …
