Electrical Characterization And Detection Of Blood Cells And Stones In Urine, Nida Nasir

Dissertations

Urine contains an immense amount of information related to its physical, chemical, and biological components; hence, it is a promising tool in detecting various diseases. Available methods for detecting hematuria (blood in the urine) are not accurate. Results are influenced by many factors, such as, health and vitals of the patients, settings of the equipment and laboratories, which leads to false positive or false negative outputs. This necessitates the development of new, accurate, and easy-access methods that save time and effort. This study demonstrates a label-free and accurate method for detecting the presence of red and white blood cells (RBCs …

Do We All Agree? A Mixed-Methods Study Of The Impact Of Climate Strength On Psychological Safety, Team Learning, And Team Performance, Taylor Harrell

Dissertations

The majority of today’s organizations rely on teamwork to drive innovation and achieve success. Evidence suggests that two constructs—psychological safety and team learning behavior—demonstrate significant predictive power on performance. Existing research posits that the more psychologically safe a team feels, the more it can learn, which enhances its performance. While organizational literature has established links among psychological safety, team learning, and team performance, the conditions under which these relationships are enhanced or diminished are less clear.

Recent studies indicate that climate strength is a factor that significantly influences the relationship between climate variables and outcomes. Climate strength refers to the …

The Development Of The Simulation Thinking Rubric, Jessica Louise Doolen

Dissertations

High fidelity simulation has become a widespread and costly learning strategy in nursing education because it can fill the gap left by a shortage of clinical sites. In addition, high fidelity simulation is an active learning strategy that is thought to increase higher order thinking such as clinical reasoning and judgment skills in nursing students. Nursing educators who utilize curriculum planned high fidelity simulation activities measure simulation learning outcomes with various instruments. However, few can quantify learning in nursing students due to high fidelity simulation and most are not supported by a theory of learning. This methodological study sought to …

Predictors Of Quality Of Life Of Elderly End-Stage Renal Disease Patients: An Application Of Roy's Model, Celia G. Hay

Dissertations

There is increasing recognition that what matters most to chronically ill patients is how well they are able to function and how they evaluate the quality of day-to-life. Understanding the impact of chronic illness and associated treatment on functioning and well-being in the physical and psychosocial dimensions of older people's lives is essential. In 2004, over half of all new patients starting dialysis were 65 years of age or older (USRDS, 2004). The physical and psychosocial impact of end-stage renal disease may lead older hemodialysis patients to withdraw from treatment and die from uremia, rather than live with seriously diminished …

Maternity nurses work closely with biological families as they integrate the infant into the family unit; however, the nurse's role with adoptive families focuses on caring separately for the birth mother and the infant being relinquished for adoption. This study seeks to describe the process of adoptive parenting from the perspective of the adoptive parent. An exploratory field design based on grounded theory methodology was used.

The Experience Of Decision-Making Among Telephone Advice/Triage Nurses, Ann M. Mayo

Dissertations

The role of the telephone advice/triage nurse is both complex and demanding. All decisions are made while assessing patients without seeing or touching patients. In addition, the role is often developed to decrease health care costs which can be perceived by nurses as being in conflict with their nursing beliefs. The ambiguous nature of the role makes these nurses' daily experiences with decision-making a challenge. Using a phenomenological method, the lived experience of decision-making among telephone advice/triage nurses was explored by conducting multiple interviews with ten nurses.

Interventions included a) consistent use of a phlebitis infiltration scale; b) maintaining a clean, dry, and intact dressing with …

Effect Of Sedative Music And Scheduled Rest On Anxiety, Pain, And Myocardial Oxygen Demand During Chair Rest In Adult Postoperative Open-Heart Patients, Jo A. Voss

Dissertations

Open-heart surgery patients in ICU report anxiety and pain with chair rest despite administration of opioid analgesics. In addition, chair rest increases myocardial oxygen demand (MVO2). Non-pharmacological, complementary methods (such as sedative music and scheduled rest) used to reduce anxiety, pain, and MVO2 during chair rest warranted further investigation. The conceptual framework was based on the transactional model of stress and coping. A 3-group pretest-posttest repeated measures experimental design examined the effect of music and rest on anxiety, pain sensation, and pain distress and MVO2 during chair rest in adult postoperative open-heart surgery patients.

Between This World And The Next: The Lived Experience Of Having A Life-Threatening Illness, Janna C. Roop

Dissertations

Wonderings about hospice patients' experience of dying evolved into the question, "What is it like to have a life-threatening illness?" That question guided this interpretive phenomenological inquiry. Phenomenology is a philosophy that seeks to rediscover the rich meaning lying hidden beneath the surface of everyday. Phenomenology's quest is to coax that which has been concealed out into the light. It is a call to re-dis-cover what Martin Heidegger (1959/1966) might call the mystery of Being. What is it that anesthetizes us to the wonder of our everydays? What is it about the ordinary that blinds us to its depth? We …

The Relationship Between Perceived Clinical Decision Making Ability And Medication Dosage Calculation Ability Of Registered Nurses, Lynn Marie Stover Nichols

Dissertations

To be an effective registered nurse, one must be able to integrate clinical decision-making skills into the medication calculation process in order to provide safe and effective care.

Drug Reviews: Cross-Condition And Cross-Source Analysis By Review Quantification Using Regional Cnn-Lstm Models, Ajith Mathew Thoomkuzhy

Dissertations

Pharmaceutical drugs are usually rated by customers or patients (i.e. in a scale from 1 to 10). Often, they also give reviews or comments on the drug and its side effects. It is desirable to quantify the reviews to help analyze drug favorability in the market, in the absence of ratings. Since these reviews are in the form of text, we should use lexical methods for the analysis. The intent of this study was two-fold: First, to understand how better the efficiency will be if CNN-LSTM models are used to predict ratings or sentiment from reviews. These models are known …

Lightgwas: A Novel Genome-Wide Association Study Procedure, Bruno Ambrozio

Dissertations

This dissertation proposes LightGWAS, a novel machine learning procedure for genome-wide association study (GWAS) based on LightGBM and k-fold cross-validation. The conducted literature review identified that the currently available GWAS implementations rely on massive manual quality control steps to address statistical issues, such as controlling for false-positive inflation and power reduction. It also showed they demand a specific GWAS method for each type of genomic dataset morphology, which consequently increases the human dependency and open margins for misleadings. LightGWAS is a potential single, resilient, autonomous and scalable solution to address such concerns. Through this research, LightGWAS was contrasted against the …

Useful For Life: Women, Girls, And Vocational School Reform In Chicago, 1880-1930, Ruby Oram

Dissertations

This dissertation explores how the competing efforts of women to prepare girls for wage-earning and homemaking shaped the development of vocation programs for female students in Chicago schools between 1880 and 1930. Histories of vocational education have neglected the role of women as school reformers and suggested that boys rather than girls were the primary focus of new work-oriented classes in urban public schools. Using Chicago as a case study, this dissertation uncovers how groups of women social reformers, educators, and trade unionists promoted vocational programs to protect school-aged girls from dangerous working conditions, steer girls into "wholesome" occupations, and …

Black Males Accessing And Usage Of Sex Education In Mississippi, Devin D. Moss

Dissertations

A Single Camera 360-Degree Real Time Vision-Based Localization Method With Application To Mobile Robot Trajectory Tracking, Khomsun Singhirunnusorn

Dissertations

This dissertation proposes a new method for real time vision-based localization in the full 360-degree area around a 3D reference object. In the past, Mirage pose estimation was developed for multi-camera systems. To achieve 360-degree localization with a single camera, we introduce the Mirage-S pose estimation method that uses a single camera given a 3D reference object as input. Mirage-S finds the solution by using an iterative numerical method with non-linear equations. This dissertation splits the localization problem into three parts: 360-degree 3D object recognition, 360-degree pose estimation, and 360-degree localization application. First, 360-degree 3D object recognition is required to …
