The Managerial Activities And Leadership Roles Of Five Achieving The Dream Leader College Presidents, Teresa Marie Mace

Graduate Theses and Dissertations

A significant increase in community colleges' (CC) presidential retirements is resulting in a huge loss of critical knowledge and experience. Recognition of this has led to numerous efforts and initiatives to prepare future community college leaders. These efforts have included numerous attempts to identify the competencies, skills, and leadership traits considered essential to performing the president's job. Unfortunately, most of the topics identified in self-reported assessments and personal interviews were not based on actual observations of what successful presidents do.

Unlike studies about community college presidents over the last 30 years, this study utilized Henry Mintzberg's (1968) structured observation methodology …

Towards The Total Synthesis Of Antascomicin B. Efforts To Construct The C1-C21 Fragment, Juliette Rivero-Castro

Graduate Theses and Dissertations

Antascomicin B is a macrolide isolated from a strain of Micromonospora. It possesses structural similarities to FK506 and rapamycin and exhibits potent binding ability to FKBP12. Recent reports suggest that small molecule ligands of FKBP12 possess potent neuroprotective and neurodegenerative properties in mouse models of Parkinson's disease. Our approach to the C1-21 fragment of antascomicin B involves an asymmetric amino-Claisen rearrangement originally developed by Tsunoda et al.35 report the scalability of the preparation and rearrangement of an allylic amide possessing a silyloxy group at the terminal position of the alkene. The Tsunoda-Claisen rearrangement uses inexpensive (S)-α-methylbenzylamine as the chiral …

Molecular And Biochemical Mechanisms Of Pathogenesis In The Maize Foliar Pathogen Cercospora Zeae-Maydis, Winfred-Peck Dorleku

Graduate Theses and Dissertations

GLS is a serious foliar disease of maize, a major staple crop grown commercially in the USA for both human and animal feed production, and increasingly, for ethanol production. The disease is caused by two Cercospora species, C. zeae-maydis and C. zeina, both of which infect maize in the USA and in other parts of the world, with yield losses potentially greater than 50%, depending on local conditions. In culture, C. zeae-maydis produces a phytotoxic, host non-specific perylenequinone, cercosporin, and abscisic acid (ABA), for which there is no known pathological or physiological function in the fungus. Experimental evidence indicates …

Consumer Adoption Of Health Information Systems, Sankara Subramanian Srinivasan

Graduate Theses and Dissertations

At nearly 18 percent of the country's GDP, the U.S. healthcare industry continues to wrestle with growing cost and a quality of care that does not match the increased spending. The dominant focus to date has been on promoting Health IT (HIT) system implementation and digitizing health records at the provider's end, with scant attention to the role of the patient in the healthcare process. The source of inefficiency in the healthcare system is not only on account of shortcomings at the provider's end but also due to non-compliance (such as failing to adhere to medication advice and follow-up visits) …

Examining Written And Spoken Fast-Mapping Abilities In Children With And Without Language Impairment: A Feasibility Study, Brooke Rice

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Linguistic skills foundational to literacy success are skills such as phonology, morphology, and orthographic knowledge. Phonological awareness, the awareness of specific units of sounds within words, and morphological awareness, the meaningful units which make up words, have been studied in depth and received recent attention in research. Phonological awareness has been attributed to increased literacy abilities of written word decoding, syllable analysis, and word recognition (Stackhouse, 1997). Additionally, morphological awareness has been attributed to increased literacy abilities of sight word reading, decoding, reading comprehension, and spelling (Carlisle, 1995, 2000; Carlisle & Nomanbhoy, 1993; Wolter, Wood, & D’zatko, 2009). Orthographic awareness, …

Aerodynamic Performance And Particle Image Velocimetery Of Piezo Actuated Biomimetic Manduca Sexta Engineered Wings Towards The Design And Application Of A Flapping Wing Flight Vehicle, Anthony M. Deluca

Theses and Dissertations

Considerable research and investigation has been conducted on the aerodynamic performance, and the predominate flow physics of the Manduca sexta size of biomimetically designed and fabricated wings as part of the AFIT FWMAV design project. Despite a burgeoning interest and research into the diverse field of flapping wing flight and biomimicry, the aerodynamics of flapping wing flight remains a nebulous field of science with considerable variance into the theoretical abstractions surrounding aerodynamic mechanisms responsible for aerial performance. Traditional FWMAV flight models assume a form of a quasi-steady approximation of wing aerodynamics based on an infinite wing element model (BEM). An …

John Dewey's Instrumentalism: A Cultural And Humanist View Of Knowledge, Philip R. Allman

Theses

My thesis is an attempt to show the brilliance and novelty of John Dewey's theory of knowledge, instrumentalism. The main objective of my thesis is to explain Dewey's theory of knowledge, which he coined instrumentalism, and to describe how instrumentalism as a theory of knowledge overcomes the pitfalls of competing theories within the philosophical tradition. Dewey's theory of instrumentalism does not assume that ideas are mental entities nor that ideas are true if they somehow match or fit with the object in question; thus, Dewey's theory presents a different view opposed to what we have usually called coherence, or correspondence …

Energy Development In Africa And The Performance Of Renewable Energy Projects, Yohannes Haile

Student Scholarship

Africa has abundant energy resources; however, it is estimated that no more than 30% of its population has access to reliable and sustainable grid electricity. Furthermore, only 50% of the countries in Sub-Saharan Africa (SSA) are expected to have universal access to electricity by 2050. Literatures identify affordability, financing mechanisms, and policy instruments as key factors for the performance of renewable energy projects. Our research data has revealed that the performance of renewable energy systems cannot be viewed or determined in isolation (contextual reduction) from the social system of the host community. Furthermore, the performance of renewable energy projects is …

Soy Mi Cuento: Latina Students Bridging Multiple Worlds In Independent Schools, Lillian Díaz-Imbelli

Education Doctoral

The dissertation explores the hybrid identity, mestiza consciousness (Anzaldúa, 1999), of Latina graduates of independent schools. Latinas currently represent one of the lowest performing, fastest growing, youngest ethnic minority groups in the United States (United States Census, 2010), and the smallest demographic in independent schools (Torres, 2012). Education offers Latinas academic and social capital for economic advancement and college opportunity (Gándara & Contreras, 2009; Santiago, 2013); independent schools are an important entry to gaining this capital. Latinas attending independent schools often enter heterogeneous educational environments for the first time and find the need to explore their identity more salient (French, …

Implementing Innovation With Ambidextrous Leadership In Small And Medium Enterprises., Deborah L. Pearce

Education Doctoral

Implementation was an overlooked aspect, with a paucity of research until the 1990s. Although scholarly and practical research grew, the preponderance focused on large established organizations. Only more recently have small and medium enterprises (SMEs) received attention. Yet, economic vitality depends on SME success. The study investigated innovation implementation in SMEs. Focus was on ambidextrous leaderships, senior leaders’ efforts to advance their organizations by ensuring capabilities for both current and future innovations. The study identified how senior leaders’ individual orientations motivated innovation and its implementation. Using a concurrent embedded mixed method design (Creswell, 2009), quantitative data was collected using a …

The Effect Of Service Dog Partnership On The Mental Health Status Of United States Veterans: A Quantitative Analysis Using The Sf-36v2 Mental Health Survey, Colleen Mclaughlin

Education Doctoral

Post Traumatic Stress Disorder (PTSD) is a historically significant problem for soldiers and Marines in the United States military. A host of recent research supports this claim, and lends itself to the question of why more is not being done to help those who suffer from combat related stress (Friedman, 2011; Kuehn, 2012; Marlantes, 2011; Sher, Braquehais, & Casas, 2012). When considering what effect service dogs might have on the mental health status of United States veterans, this study focused on the following research questions based on the SF-36v2 Mental Health Survey: What effect does partnership with a service dog …

Nature Of Deaf Mentoring Dyads: Role Of Subjugated Knowledge, Jason D. Listman

Education Doctoral

Research has indicated that the United States is lagging behind the rest of the world in producing science, technology, engineering, and math (STEM) majors and career professionals. The National Science Foundation has launched one particular initiative to address this need which is centered on underrepresented communities. Matching mentoring dyads based on similar social identities may provide necessary role models (Davidson & Foster-Johnson, 2001) and unlock subjugated knowledge (Collins 2000) about how to be both deaf and scientist. Among their underrepresented counterparts, deaf individuals are disproportionately underrepresented in STEM careers (NSF, 2011). The leakage in the STEM pipeline between undergraduate enrollment …

Cross-Cultural Competence In Transnational Medical Education Partnership, Greta Rosalie Strong

Education Doctoral

The purposes of the study were to discover the knowledge, behaviors, and skills that foster cross-cultural competence in transnational medical education partnership and to unite the research process with theory development. Selected literature and a modicum of concepts limited the framing of this study from an existing theoretical framework. Such a framework would have been useful in providing the basis for training of health care professionals involved in transnational ventures. To accomplish this, the research used a qualitative grounded theory approach to explore the experiences of twenty-five professionals involved in transnational medical education partnership. The research was conducted at Weill …

The Relational Algebra Toolkit: A User-Friendly Approach To Presenting And Processing Relational Algebra Queries On The Web, Jeremy J. Miller

Theses and Dissertations - UTB/UTPA

Relational algebra is the mathematical basis of tools to express and optimize queries on relational data. However, there exists no convenient way to directly use, express, store, render, visualize, and execute relational algebra over the Web. Educators and practitioners are limited to creating relational algebra expressions using TeX or equation editors which cannot execute them. This work presents a solution to this issue: the Relational Algebra Toolkit (RAT). Relational data and queries are represented using purpose-built XML vocabularies, to be both machine-processable and serializable. Encoded relational algebra expressions can be rendered as parenthetical expressions and as syntax trees, translated to …

Theses and Dissertations

The purpose of this study was to further examine the relationship between family leisure variables and the dependent variables of family functioning and satisfaction with family life among a broad, national sample of Canadian families using the Core and Balance framework. Specifically, this study examined how both family leisure involvement (core and balance) and family leisure satisfaction contributed to the explanation of variance in family functioning and satisfaction with family life. Because the data were nested in families, this study accounted for family-level variance by incorporating mixed modeling. The sample consisted of 943 families across Canada including one parent and …

Doctor Of Philosophy, Ha Youn Shin

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Signal Transducer and Activator of Transcription 5 (STAT5) is a transcription factor that is critical for various biological processes including hematopoiesis, liver metabolism and mammary gland development. However, persistent activation of STAT5 has been causally linked to human leukemia and solid tumor formation. Since STAT5 is important for normal physiological functions and aberrant activity can promote cancer, accurate regulation of STAT5 is essential. As a transcription factor, STAT5 must gain entry into the nucleus to act, and one means of controlling its activity is to regulate its cellular localization. This study explores the nuclear trafficking mechanisms of STAT5a that may …

Entanglement In Low Dimensional Systems, Raul Santos

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

In the ground state of gapped systems, the entanglement entropy of a subsystem A scales with the length of the boundary of A. This observation suggests that the entanglement properties of the sub- system can be described in terms of degrees of freedom living in the boundary of A. We will discuss the the connection between en- tanglement properties and effective boundary descriptions in spin systems in one and two dimensions. In one dimension we present analytic results for the spin S = 1, Affleck-Kennedy-Lieb-Tasaki (AKLT) ground state entanglement, characterized by negativity and entanglement spectrum. We also discuss a generalization …

Stimulated Raman Adiabatic Passage Between Metastable And Rydberg States Of Helium, Yuan Sun

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

We investigate the coherent population transfer and associated effects for a three level atomic system, with the third level being a Rydberg state. The scheme adopted here is the stimulated Raman adiabatic passage (STIRAP). An atomic beam of metastable helium is orthogonally crossing two laser beams in a tunable dc electric field. The ir laser of 790 - 830 nm connects the triplet 3P state to the Rydberg states (n = 12 - 50) and the uv laser of 389 nm connects the metastable triplet 2S state to the triplet 3P state. A third laser of 1083 nm driving 2S-2P …
