Incidence And Clinical Predictors Of Risk Factors For Inappropriate Shock In Patients With Implantable Cardioverter-Defibrillators, Shu-Ling Lo Phd

Dissertations

Sudden cardiac death (SCD) is a major unresolved medical problem worldwide. Although Implantable Cardioverter-Defibrillators (ICD) are highly effective in diagnosing and treating life threatening arrhythmias, inappropriate shock therapy (IST) occurs in approximately 5-20% of ICD recipients. IST results in pain, anxiety, induction of ventricular arrhythmias, decreased battery longevity, and even death. Researchers studying clinical predictors of IST have drawn findings based on single case studies with small samples or with outdated data. This study filled this gap by describing the incidence and co-existing clinical predictors of IST. Methodology This descriptive, retrospective study analyzed the incidence and clinical predictors of IST …

An Exploratory Study Of Functional Status In Post Cardiac Arrest Survivors Discharged To Home, John J. Whitcomb Phd

Dissertations

Cardiopulmonary arrest is a major health problem, claiming 350,000 to 450,000 lives per year in the United States, but survival has increased to 49% from the use of Automated External Defibrillators (AED) by lay personnel. Leidy's work on functional status is a comprehensive framework to describe functional status and has not been used in this population. The specific aims of the project were to describe perceived functional capacity, physical functional performance, mental health, symptom distress, and demographic factors in survivors of cardiopulmonary arrest after discharge to home and to examine the relationship among perceived functional capacity, mental health and physical …

Connecting The Dots: A Study Of An Innovative Principal Preparation Program's Impact On The Mental Models And On-The-Job Behaviors Of Aspiring School Leaders, Rich Newman Edd

Dissertations

Despite years of criticism aimed at university-based principal preparation programs, most of these programs continue to be judged less than successful in producing effective school leaders. Furthermore, there is also little rigorous and systemic research about principal preparation in general; there is even less work focused on understanding how preparation programs might assist emerging school leaders in developing the sorts of intellectual capacities needed to be successful in an era when principals are expected to be instructional leaders and work with teachers to improve student achievement. Consequently, little is known about how principal preparation programs can help individuals (a) incorporate …

Enhancing Motivation Using The Constructs Of Flow In Museum Education Activities, Maria C. Grant Edd

Dissertations

While many extol the general value of museum fieldtrips, few can describe the specific parameters needed to make the excursion an educational benefit. Oftentimes, a day at the Museum of Natural History or time spent at the local art gallery is casually put into place with little forethought or attention to activity details. This research intended to utilize the parameters of flow theory and children's interest to investigate the phenomenon of student motivation while viewing an exhibit. Informal learning environments offer educators the opportunity to look beyond the halls of their campus in a manner that allows augmentation of curriculum …

The Lost Journals Of Sylvia Plath, Kimberly Dawn Knutsen

Dissertations

Sylvia Plath is one of the few authors who has been posthumously awarded the Pulitzer Prize. Plath's exceptional literary career is not limited with that. When twentieth-century literary history is examined, it becomes patent that no writer has created such an enormous impact as Sylvia Plath. Furthermore, no writer or poet has been as misunderstood as in the case of Plath. In addition, no writer or poet has been labeled often as "schizophrenic" or "mad" by scholars or researchers who do not have the slightest education in psychology or psychopathology. Therefore, the works written on Plath, or the studies that …

The Role Of Embeddedness Factors In Predicting The Paths Of The Unfolding Model Of Voluntary Turnover, Lynn R. Kalnbach

Dissertations

A great deal of research has been conducted to determine the relationship between the job satisfaction of employees and the likelihood of their leaving or intending to leave an organization. However, research addressing other reasons why employees may leave their organizations has been lacking. Lee and Mitchell (1994) created the unfolding model of turnover to better define and classify the process employees go through in making decisions to leave their organizations. This model suggests that many people decide to leave their jobs/organizations for reasons other than job dissatisfaction.

In a separate stream of research, Lee and Mitchell and their colleagues …

Managing Susceptibility To Hereditary Breast And Ovarian Cancer, Cynthia E. Perry Phd, Msn, Rn

Dissertations

The recent identification of Breast Cancer 1 (BRCA1) and BRCA2 genes offers an opportunity for high-risk individuals to learn whether they may be genetically predisposed to develop breast and/or ovarian cancer. The purpose of this study was to examine how unaffected women, identified as BRCA positive and variant of uncertain significance (VUS) mutation carriers, managed their susceptibility to hereditary breast and ovarian cancer (HBOC). Thirty North American women ranging in age from 22 to 60 years responded to open-ended interviews. These interviews were analyzed using constant comparative method to generate a grounded theory. Managing Susceptibility was identified as the basic …

Development Of An Analogue Of A Response-Class Hierarchy, Daniel B. Shabani

Dissertations

Within the operant conditioning literature, there exists the concept of the functional response class. A functional response class is defined as a collection of responses that all produce the same outcome. If the members of a response class occur in a predictable order, a response-class hierarchy is said to exist. A hierarchy refers to a specific type of response class in which each member of the response class may be temporally determined along various dimensions (e.g., response effort, immediacy of reinforcement, magnitude of reinforcer). The response-class hierarchy has received relatively little conceptual attention over the years and, not surprisingly, there …

Single-Electron Capture Processes In Slow Collisions Of He^2+ Ions With Molecular Targets, Osama Abu-Haija

Dissertations

Translational energy-gain spectroscopy (TES) has been used to investigate state-selective dissociative and non-dissociative single-electron capture processes in low-energy collisions of He²⁺ ions with O₂ , H₂ O, CO₂ , N₂ , and NH3 at impact energies between 100 eV and 1600 eV. The measured energy spectra for theHe²⁺ -O₂ and H₂ O collision systems show that the dominant exit channel is due to dissociative transfer ionization (DTI), single-electron captureaccompanied by ionization of the molecular target-ion, at the lowest collision energies. As the impact energy is increased non-dissociative single-electron capture (SEC) into the …

The Relationship Of Race And Ethnic Identity To Perceptions Of Multicultural Counseling Competencies, Tonita C. Baines

Dissertations

Multicultural counseling competencies refer to the awareness, knowledge, and skills that are considered important for counselors to possess when working with culturally diverse clients (Constantine, 2002; Constantine & Ladany, 2001). Relatively few studies have looked at factors that may impact a client'sperception of a counselor's multicultural competence. The purpose of the present study was to investigate the relationship between a person's race, ethnic identity, and his/her ratings of the importance of 31 multicultural counseling competencies. A total of 304 undergraduate students (152 African-American and 152 White) from a large Midwestern university were surveyed to determine if there was a relationship …

A within-subject ABCB reversal design was used. Each participant was exposed to the following pay and feedback conditions: hourly pay …

A Behavioral Model For The Assessment And Management Of Dehydration In Older Adults, Leilani Feliciano

Dissertations

Dehydration is a serious health concern in the elderly, constituting 1 of the 10 most common causes for hospitalization in this population (Sanservo, 1997). Previous research on dehydration has typically been conducted within nursing home settings (Chidester & Spangler, 1997; Holbren, Hassell, Williams, & Helle, 1999; Spangler, Risley, & Bilyew, 1984) without specific attention to the variables maintaining dehydration for any given individual. A functional behavioral approach to assessment and prevention or intervention for dehydration would involve identifying maintaining variables in the environment that can be altered to produce effective, non-intrusive interventions to increase healthy fluid consumption. The current project …

Willa Cather: The Letters And Novels Of A Romantic Modernist, Lisa Bouma Garvelink

Dissertations

Willa Cather believed the primary goal of art was to simplify, but she never believed the world to be a simple place. Her letters reveal abundant conflicted feelings about her own place in the world, while also revealing a concomitant determination to succeed at any cost. From O Pioneers! (1913) to Sapphira andthe Slave Girl (1940), her novels vary vastly, evidencing a complex dialectic between romantic absolutes and modernist uncertainties. Even in the novelsmost critics would see as notably romantic--specifically her earlier works--the modernist temperament and techniques create recognizable tension. Just as significantly, in her later, darker novels the romantic …

Rank-Based Methods For Repeated Measures Data Under Exchangeable Errors, John Kloke

Dissertations

Rank-based estimation methods provide alternatives to least squares. Estimators derived via least squares are generally not robust to aberrant observations.Rank-based methods for linear models generalize traditional Wilcoxon procedures in the simple location models and are robust.

In the usual linear model it is assumed that the errors are independent. In the case of repeated measures data several observations are taken on each experimental unit. In the case of longitudinal data the measures are taken on the same subject over time. As such an independence assumption does not seem valid. A common solution to this is to make an assumption on …

Starlight Drive, William R. Reynolds Jr.

Dissertations

Starlight Drive is a book-length manuscript of poems that reflects my abiding interest in how poetry can use the fiction writer's tools, such as characterization and setting, without sacrificing the beauty of the lyric. Like Rodney Jones, I write about my north Alabama childhood filtered through the lens of my adult life here in the Midwest. My field of perception does not begin in a cotton field like Jones', but on a cul-de-sac in a middle-class neighborhood of Huntsville, where my father was an engineer for NASA. The poems in my manuscript show my protagonist moving through a landscape peopled …

The Practice Of Continuous Improvement In Higher Education, Deborah M. Thalner

Dissertations

Studies on the use of Total Quality Management (TQM) within higher education have primarily focused on the implementation of TQM as an institutional initiative. While TQM has been successful in business and industry and has seen some limited success in higher education, the most recent studies on its usein higher education indicate that it has not been successful institution-wide, and in many cases has been abandoned after two to three years. The problem, therefore, is one of a perceived need for continuous improvement in coupled with mixed results from previous attempts at implementation. This research study focused on higher education's …

Essential Features Of Cultural Proficiency In American International Schools In Latin America: A Delphi Study, Rebecca Mcbride Bustamante Edd

Dissertations

American international schools in Latin America can play a vital role in preparing future leaders to effectively interact with people of diverse cultures. These schools provide ideal settings for exploring how policies, programs, and practices that reflect diverse perspectives and encourage intercultural learning might enhance global leadership development. Multidisciplinary reviews of the literature reveal a dearth of studies examining culture and leadership development in American international schools in Latin America. The model of cultural proficiency provides a comprehensive framework for exploring how these schools might proactively and effectively respond to diversity in a cross-cultural environment and develop globally competent leaders. …

Unintended Pregnancy Prevention And Active Duty Women, Min S. Chung-Park Phd, Msn, Whnp

Dissertations

Studies have shown that a structured education program for women decreases risky sexual behavior identified as vulnerable for AIDS. However, the outcomes from a structured, repeated, educational intervention in reducing the rates of unintended pregnancies have not been studied in military females who are considered as a high risk. The purpose of this quasi-experimental longitudinal study was to implement and evaluate the effects of a reproductive health educational program regarding knowledge, attitudes, decisional balance, self-efficacy, stages of change, and contraceptive use, and to identify independent variables most likely to predict behavior change in the use of contraceptives among single, active …

Stabilization Of Curtain Coater At High Speeds, Peeyush Tripathi

Dissertations

High-speed curtain coating is an emerging technology trying to gain commercial acceptance by the paper industry as a pre-metered and non-impact coating process. Curtain coating could offer enormous economic and process advantages over conventional coating methods due to non-impact and excellent coverageat reduced coat weights. Due to non-impact and non-contact type of coating operation, curtain coating can operate with fewer sheet breaks or the strength requirements of the base sheet can be greatly reduced. High speed curtain coating for commodity coated grades like LWC is still a challenge. Relationship between various process, basesheet and coating variables and their mechanism must …
