Determining Content Validity For The Transition Awareness And Possibilities Scale (Taps), Melynda Burck Ross

Dissertations

The Transition Awareness & Possibilities Scale (TAPS) was crafted after an extensive review of literature was conducted to find research that examined and described specific aspects of transition programming: inputs, including supports and skill instruction; processes, including parent and support provider perceptions of the transition experience; and outcomes, including quality of life and traditional, quantitatively-measured outcomes. Once developed, the TAPS will allow a teacher or transition coordinator to know what information a family is lacking about transition planning and adult service options for students with disabilities who need extensive or pervasive supports.

In this research, content validity was used as …

Barriers And Enablers Of Interdisciplinary Research At Academic Institutions, Leslie Suzanne Thornton Butler

Dissertations

This research study examines the factors that motivate and lead to the success of faculty members who conduct interdisciplinary research. Because a comprehensive study of the research patterns of interdisciplinary researchers has not been conducted, the main intent of this research project was to create an instrument that would measure research habits and attitudes. It is important that such research be conducted using individuals who are interdisciplinary researchers as well as disciplinary researchers. One intent of the research study was to provide comparisons between disciplinary researchers and interdisciplinary researchers. Another intent was to provide university administrators with a better understanding …

Ladies And Gentlemen, Robert John Bartholomew

Dissertations

This collection of short stories treats of the following diverse themes: the redemptive possibilities for seemingly despicable characters; the ways in which circumstances and the social environment affect characters' sexualities and personal relationships; the lengths to which characters are willing to go to get what they want, which want is often the desire to make contact with others; the struggle between characters' narcissism and their need to come to terms with a new self image, a self image which is often at odds with the one they wish for themselves; and the beauty of vulnerability. Additionally, one of the chief …

Development And Utilization Of Digital Image Correlation Techniques For The Study Of Structural Isomerism Effects On Strain Development In Epoxy Network Glasses, Stephen Robert Heinz

Dissertations

The specific aim of this dissertation is to present the findings regarding the effects of molecular structure on macroscopic mechanical performance and strain development in epoxy networks. Network molecular structure was altered through monomer isomerism and crosslink density/molecular weight between crosslinks. The use of structural isomerism provided a pathway for altering mechanical performance while maintaining identical chemical composition within the network. Isomerism was investigated primarily by the curing of diglycidyl ether of bisphenol A (DGEBA) using either the para- or meta-substituted derivatives of diaminodiphenyl sulfone (DDS). Additional insights into isomerism were gained through the investigation of networks composed of either …

Principals’ Perceptions Of Readiness For Their Evolving Roles In High-Stakes Environments, Angela Marie Huff

Dissertations

Principals are leading schools during an evolving time where preparation may not have prepared principals fully for the task of school leadership. The past decade has revealed an escalation in the disapproval of principal preparation programs and participants in these programs insist that these schools be held accountable (Levine, 2005). However, in revamping preparation programs, one must focus on student selection, curriculum and course content, pedagogical strategies, internships, and field experiences (Orr, 2006). Some have suggested that the job of principal may have become impossible for all but a few super leaders (Lashway, 2003). The requirements of the job may …

A Historical Perspective Of Testing And Assessment Including The Impact Of Summative And Formative Assessment On Student Achievement, Carole Sanger Brink

Dissertations

In 2007, Georgia developed a comprehensive framework to define what students need to know. One component of this framework emphasizes the use of both formative and summative assessments as part of an integral and specific component of the teachers' performance evaluation. Georgia administers the Criterion-Referenced Competency Test (CRCT) to every elementary student in Grades 1 though 8. Before 2008, the state tested eighth-grade students on a quality core curriculum. In 2008, the state began testing students on a Georgia Performance Standard curriculum. A direct comparison of the curriculum change should have contained items to test both curriculums. However, this was …

Effects Of Implementing A Formative Assessment Initiative, Thomas A. Stewart

Dissertations

This dissertation supports the work of Black and Wiliam (1998), who demonstrated that when teachers effectively utilize formative assessment strategies, student learning increases significantly. However, the researchers also found a “poverty of practice” among teachers, in that few fully understood how to effectively implement formative assessment in the classroom. This qualitative case study examined a series of voluntary workshops offered at one public middle school designed to address this poverty of practice. Data were gathered via semi-structured interviews. The researcher used constant comparative analysis to discover patterns in the data for the following four research questions: (1) What role did …

An Analysis Of Burmese And Iraqi Resettlement Location And Assimilation In A Midsized City: Implications For Educational And Other Community Leaders, Donna Schiess Renaud

Dissertations

Refugees face different circumstances than other immigrants regarding housing in initial resettlement in the U.S. Refugees have no choice of their initial residence as this is determined in advance by the resettlement agency. Refugees who belong to minority ethnic groups and who have little education or skills may experience discrimination and hostility from local citizens. Resettlement areas that are high in population density, rental units, minorities, crime, unemployment, inadequate transportation, and low income may present additional barriers to cultural and economic assimilation.

This mixed-method study had a twofold purpose. The first was to describe quantitatively how the initial resettlement address …

The Exploration Of The Relationship Between Guessing And Latent Ability In Irt Models, Song Gao

Dissertations

This study explored the relationship between successful guessing and latent ability in IRT models. A new IRT model was developed with a guessing function integrating probability of guessing an item correctly with the examinee's ability and the item parameters. The conventional 3PL IRT model was compared with the new 2PL-Guessing model on parameter estimation using the Monte Carlo method. SAS program was used to implement the data simulation and the maximum likelihood estimation. Compared with the traditional 3PL model, the new model should reflect: a) the maximum probability of guessing should not be more than 0.5, even for the highest …

On The Interpenetration Of Nature And Spirit: A Loving Relationship With The Earth And Our Natural Environment, Christina Marie Gould

Dissertations

In this dissertation I examine our relationship with the Earth and our natural environment by clarifying what it means to be human. I do this by looking at the interpenetration of spheres of being or philosophical anthropology to articulate how the human being is the dynamic meeting point of life and spirit. In this interpenetration of life and spirit, the task of the human being as loving flashes forth. On the basis of this task, it is possible to realize a loving relationship with the Earth and our natural environment that is not based on domination or use. To understand …

Identifying Competencies Of Aoda Clinical Supervisors For Integration Into Rehabilitation Counselor Training Curriculum: A Delphi Study, Marissa Mckee

Dissertations

This study preliminarily identified clinical supervision competencies needed for alcohol and other drug abuse (AODA) clinical supervisors for integration into rehabilitation counselor training (RCT) curriculum. The Delphi method via LimeSurvey® was utilized to identify competencies specific to AODA clinical supervision. A panel of six experts in RCT and AODA clinical supervision completed five rounds of data collection beginning with an open-ended question. Consensus and stability of responses were calculated following Rounds 2-5 of data collection. Panelist fatigue resulted in data collection being discontinued after Round 5, prior to a consensus or stability of responses being reached. A total of 115 …

Evolution, Terror Management Theory, And Humans’ Relationship With Nature, Joshua Warren Vinocour

Dissertations

This study investigated the savannah hypothesis, an evolutionary explanation for human environmental preference. It aimed to address some of the methodological shortcomings of prior research while simultaneously investigating the role of non-evolutionary influences, such as existential anxiety and individual differences. Ninety-eight undergraduate participants were shown photos of Natural, Mixed, and Built settings and rated the visual attractiveness of each photo. Results showed that Built scenes were preferred over Natural and Mixed scenes, in contradiction to the savannah hypothesis. Existential anxiety, however, did not appear to influence photo ratings. Individual differences, such as ethnicity and the quality participants’ previous outdoor experiences …

Geometric Structures On Matrix-Valued Subdivision Schemes, James J. Smith

Dissertations

Surface subdivision schemes are used in computer graphics to generate visually smooth surfaces of arbitrary topology. Applications in computer graphics utilize surface normals and curvature. In this paper, formulas are obtained for the first and second partial derivatives of limit surfaces formed using 1-ring subdivision schemes that have 2 by 2 matrix-valued masks. Consequently, surface normals, and Gaussian and mean curvatures can be derived. Both quadrilateral and triangular schemes are considered and for each scheme both interpolatory and approximating schemes are examined. In each case, we look at both extraordinary and regular vertices. Every 3-D vertex of the refinement polyhedrons …

Feminist Advocacy In Community Based Responses To Domestic Violence: Gendered Identity, Ideology And Practices, Andrea J. Nichols

Dissertations

The anti-domestic violence movement began as a feminist grassroots effort. Early feminist advocates relied on survivor-defined and social change practices rooted in feminist identity and ideology. Advocacy has evolved over time, moving from grassroots efforts into professionalized organizations, and now includes collaboration with the justice system in community based responses to domestic violence (CBR). Through inductive analysis of interviews with 26 domestic violence victim advocates and drawing from a gendered organizations framework, I examine how advocates’ feminist identity and ideology shape their practices in CBR. Findings indicate that advocates both resist and reproduce various gendered practices within traditionally feminist anti-domestic …

Stemming from data gathered in Project GEMS (Gifted Education in …

Reading Aloud And Student Achievement, Rebecka R. Spencer

Dissertations

Although numerous studies have been conducted on reading aloud to elementary students, there is a need for additional research in reading aloud to middle school students. The main question is: are the benefits of reading aloud to elementary students comparable to middle school students? Reading aloud has proven to increase elementary students‘ comprehension, vocabulary, fluency, motivation, and encourage students‘ understanding of content matter. While reading aloud is a common practice among elementary teachers and students, the practice all but diminishes by middle school (Delo, 2008; Trelease, 2006). This mixed method study was conducted in three public school districts in Missouri …

Evaluating Summer School Programs And The Effect On Student Achievement: The Correlation Between Stanford-10 Standardized Test Scores And Two Different Summer Programs, Alicia Kaye Bottorff

Dissertations

Educators have been looking for a solution to increasing yearly student achievement while at the same time ensuring that the achievement gap between students of high and low socioeconomic status does not continue to widen each year. Many studies examined show that students experience summer learning loss if not in school during the months of June through September. Because of this research, the district being studied extended their summer school program format from four-weeks to six-weeks. This collaborative, quantitative study examined assessment data from the SAT 10 to explore the correlation between middle school math and language arts test data …

Rational Ligand Design For Potential Applications In Transition Metal Catalysis, Sergey L. Sedinkin

Dissertations

Strategies to influence the steric and electronic properties of three classes of ligands were investigated. First, a compound class known as amino-dithiaphospholanes was studied. It is structurally related to phosphoramidites, which have been successfully applied in catalysis. The synthesis of amino-dithiaphospholanes was envisaged as an approach to electronically tuned phosphoramidites. General access to a variety of structurally modified amino-dithiaphospholanes from commercially available starting materials was developed. The electron donating properties of the new ligands were characterized by NMR. They were found to be more electron-donating than the corresponding phosphoramidites. The coordination chemistry of amino-dithiaphospholanes was investigated by synthesis of a …

Health Literacy And Health Promotion Behaviors Among Samoans, Katherine Tong Phd, Msn, Cfnp, Phn

Dissertations

Limited health literacy is associated with failure to engage in health promotion behaviors. Few studies examine this relationship among Samoans. This study used a cross-sectional correlational design to determine health literacy levels and their relationship to health promoting behaviors in a southern California Samoan population. Health literacy (Short form Test of Functional Health Literacy in Adults) and health promotion behaviors (Health Promotion Lifestyle Profile II) were measured in a convenience sample of 87 Samoans in southern California. Data analysis employed chi-square, t-test, and one- way ANOVA. Significant associations were found for health literacy and demographic characteristics of employment and marital …

Functional Characterization Of Putative Non-Specific Phospholipase C (Npc) In Arabidopsis Thaliana, Carlotta Antonetta Peters

Dissertations

Abstract Phospholipases are enzymes that hydrolyze phospholipids. In terms of the position of bond hydrolysis, phospholipases are classified into four major types: phospholipase C (PLC), phospholipase D (PLD), phospholipase A1 (PLA1) and phospholipase A2 (PLA2). PLC hydrolyzes phospholipids at the first phosphodiester bond, producing diacylglycerol (DAG) and a phosphorylated head group. Based on substrate specificity, PLC is divided into two distinctively different groups: phosphoinositide-specific phospholipase C (PI-PLC) and non-specific phospholipase C (NPC). There are six members of the NPC family in Arabidopsis, designated NPC1 through 6 that bears sequence homology to bacterial phosphatidylcholine hydrolyzing PLC (PC-PLC). However, their function remains …

The Police Caution As A Diversionary Mechanism. An Analysis Of The Garda Síochána Adult Caution Scheme, Graham Tolan

Dissertations

The Garda Síochána Adult Caution Scheme was established in 2006. It is among a range of alternate methods which have been introduced in recent years that are designed to divert adults away from the criminal justice system. The scheme provides a mechanism by which individuals receive a formal police caution in lieu of prosecution before the courts. It is only available to certain persons against whom there is evidence of the commission of a scheduled criminal offence and where the prosecution of such an offence is not in the public interest (An Garda Síochána, 2006:2009). This thesis examines the scheme …

Maslach's Burnout In Part-Time Faculty At A Four-Year Postsecondary Institution, Christiane Rene` Hubbard-Valentine

Dissertations

Previous researchers have suggested that many part-time faculty are over-worked, underpaid, frustrated with their faculty status, and experience stress and burnout (Antony & Valadez, 2002; Brown, 2009). Burnout may be attributed to the demands of pieced together work or other factors, but it is uncertain. Accordingly, the purpose of this quasi-experimental study was to examine burnout and demographic factors (age and gender) that contributed to burnout among part-time faculty (moonlighters, freeway flyers, and auxiliary) at a four-year postsecondary institution in the Midwest. Participants completed an online survey consisting of the Maslach Burnout Inventory Educators Survey, demographic questions, and open-ended questions. …
