Time Series For The Boolean Random Sets, Kofi Kermah Wagya

Dissertations

Although Random closed sets (RACS) are rich in modeling complex objects, its model parameter inference is simple. The most important type of the RACS is Boolean random set (BRS). BRS is a parametric model that is formed by placing random closed sets (grains) at points of a Poisson process (germs), and taking union of these sets. The radius of these grains may be fixed and known, fixed but unknown, and random. Furthermore, the intensity parameter l, which is one source of randomness in the BRS model, has been estimated by the method of Intensity, method of Minimum contrast, method of …

Exploring How Andragogical Principles May Enhance Doctoral Students’ Persistence To Dissertation Completion, Bernice Bush

Dissertations

The Doctorate is a terminal degree, in that, a student has accomplished the ultimate academic achievement within an educational field of domain. Although industries worldwide continually demand ever-advancing scholarly workforces and the innovation developments of higher thinkers, this degree has been impeded by a staggering 50% attrition rate among colleges and universities for decades. Also obstructive to degree attainment has been the phenomenological trend of the All-But-Dissertation (ABD) phase experienced by multitudes of candidates within their courses’ timelines. Researchers have studied these issues over the last century, specifically seeking relevant sources of influence among dozens of student attributes and pursuing …

Schools’ Civil Rights Obligations To English Learners: Leadership Perceptions On Key Issues, Pamela R. Schwallier

Dissertations

English Learners (ELs), who now represent nearly 10% of all K-12 public school students, 4.8 million of who speak over 400 different languages and dialects, continue to lack equitable educational opportunities as demonstrated through gaps in achievement outcomes, poor graduation rates, and identified systemic barriers related to the intersectionality of language, culture, race, and racism (Crump, 2014; DeMatthews & Izquierdo, 2017; Menken & Solorza, 2015; Morita-Mullaney, 2018; National Clearinghouse for English Language Acquisition [NCELA], 2015, 2018). This quantitative study captured over 800 K-12 educational leaders’ perspectives, via an anonymous electronic survey, on key issues regarding equitable programs for ELs that …

Novice Second-Career Teachers: Experiences And Meaning-Making Of The Transition Process, Paula Dennisse Núñez Del Rosario

Dissertations

The world we live in is in constant change. During change, people focus on the observable part of what is not there anymore and what has come in its place, not being conscious of the adaptation process that underlies the change: the transition. The transition is a process that has different phases and the development of the process is differentiated depending on the individual. Transition is also directly related to the type of experience. Although circumstances differ among individuals, it is possible to say that there are some common aspects in terms of challenges faced by all novice teachers, both …

Providing Head Start Services Amid A Global Pandemic: A Mixed Methods Explanatory Study Of Capacity, Resources, And Support, Kelly L. Vigants

Dissertations

The COVID-19 pandemic altered education in dramatic ways including immediate building closures and the implementation of virtual instruction. In March of 2020, Michigan faced a statewide shutdown on all non-essential travel as Michiganders were ordered to “Stay Home. Stay Safe.” Head Start began to provide remote services to families and students. Head Start lead teachers were charged with using virtual methods to teach their students. With little direction in the beginning and many unknowns, Head Start lead teachers used innovative methods to promote family engagement.

This study used a mixed method, explanatory sequential design to evaluate the most effective methods …

A Program Evaluation Of The Effectiveness Of Fundations And Reading Strategies Professional Development, Cecile Amy Farino

Dissertations

This program evaluation focused on a research-based reading intervention program implemented in a public school district. It also considered the professional development provided in reading strategies and the use of the program to increase students’ reading achievement levels. A problem I identified with using a reading intervention program was it did not identify student deficiencies, and educators lacked the knowledge of basic reading foundational skills to help identify students’ deficiencies. In my research, I examined one elementary school and the administrative team members’ implementation of the reading intervention program. The literature I presented focused on two phases of reading: the …

Impact Of Tier 2 Intervention Program On Student Achievement And Self-Efficacy, Barbara L. Georges

Dissertations

To address the challenges of drop-out rate and achievement gap, high schools have begun to implement intervention programs. Schools bear responsibility in addressing factors such as poor academic performance, lack of course credit, and low motivation to encourage post-secondary success. Intervention programs show promise in mitigating these factors despite variation due to lack of state or federal requirements. The most common frameworks used to address the skill gaps and deficiencies that prevent graduation are Response to Intervention (RtI) or Multi-Tiered Systems of Support (MTSS). The purpose of this study was to determine the impact of academic interventions on student achievement …

Dispositions Of Emotional Intelligence In School Principals, Efrain Martinez

The participants interviewed were novice school principals or principal coaches. The results showed that principals tend to address the needs of others more than their own. Strategies are shared on how to improve emotional intelligence. Additionally, the study provides recommendations that school districts can implement to ensure the success of school principals.

Frames Of Error: Three Behavioral Approaches To Reducing Stigma Towards People With Disabilities, Rocco Giovanni Catrone

Dissertations

What makes a person disabled is a much-debated topic with some focusing on the individuals impairments (putting the onus of disability on the individual) while others focus on how the environment (both architectural and social) exacerbates an individual’s impairments and creates the conceptualization of disability (putting the onus of disability on society). No matter how a person with a disability (PWD) is categorized, they are met with healthcare, education, and work disparities that are perpetuated both unintentionally and intentionally. This paper examines the various ways disability and subsequently stigma arises from a variety of viewpoints both within and outside the …

Preliminary Examination Of Methods For Identifying The Function Of Stealing, Brandon Ellis Mccord

Dissertations

Because low rate, covert responses are hard to observe and measure (e.g., Azrin & Wesolowski, 1974; Henderson, 1981; Jeffery, 1969; Reid & Patterson, 1976; Seymour & Epston, 1989), well-controlled behavior analytic investigations of stealing have been rare. In fact, systematic investigations to experimentally determine stealing functions have been limited to two studies targeting food (Lambert et al., 2019; Simmons, Akers, & Fisher, 2019). The dearth of studies examining stealing functions, partly attributable to low rate and covertness, may be forestalling additional intervention studies. Given the likely futility of unsystematic attempts to observe naturally occurring instances of an infrequent, clandestine response, …

Abstract

The world is struggling with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic and the need for disaster nursing education has never been more clear. Recently, the American Nurses Association reported that of the over 32,000 nurses surveyed; only 11% felt well prepared to care for a COVID-19 patient (ANA, 2020). Community health nurse educators are tasked with educating future nurses on disasters, yet, little is known about this population’s perceived competence in disaster preparedness. The purpose of this study is to describe community health nurse educators' perceived competence in disaster preparedness.

The study is a descriptive, correlational …

Tailoring Violence Prevention Programming To A Critical Care Area, Jaime Campbell

Dissertations

Abstract

Problem: Rising rates of violence in health care environments signal a need for health care workers, specifically frontline nurses, to be trained in effective de-escalation management skills. Since January 2017, there has been an increase in the number of patients categorized as aggressive with more violent patient events taking place at a selected midwestern hospital facility in the critical care department, particularly the intensive care and transitional care units.

Methods: Using a pre-post design, this project compared nurses’ verbal de-escalation skills using the English Modified De-escalating Aggressive Behaviour Scale (EMDABS) to determine effectiveness of de-escalation strategies in simulated scenarios …

Sustainability Of An Outpatient Antibiotic Stewardship Program, Kristin Smith

Dissertations

Abstract

Problem: Antibiotic stewardship is an effort to evaluate and improve the use of antibiotics by providers and patients. Antibiotic stewardship programs (ASPs) promote the appropriate use of antibiotics. There is increasing evidence that supports the use of antibiotic stewardship programs in reducing antibiotic prescribing rates while continuing to maintain safe patient care. Research supports approaches with multiple interventions and ongoing commitment to antibiotic stewardship. However, information regarding long-term sustainability of antibiotic stewardship programs is lacking. The purpose of this quality assurance project was to assess long-term sustainability of a previously implemented ASP promoting appropriate prescribing of antibiotics for the …

Missed Appointment Rates And The Implication On Primary Care Practice, Kelly Martin

Dissertations

Problem: Missed appointments cost primary care facilities money and resources through lack of utilization. When patients fail to attend their scheduled appointment the providers are non-productive when they could be seeing other patients that are potentially moved to other days, sending patients to other providers, or worse sending patients to the prompt care or the Emergency Department for care. The missed appointment rate at Office A Primary Care is approximately ten percent, while Office B has a nearly 11% missed appointment rate. Both facilities make reminder calls to patients the day before their appointments to remind them of their appointment …

Dissertations

Ex-offenders return home to family and friends every day in the United States of America; seeking to reintegrate with family and society. Ex-offenders recidivate as well due to numerous reasons and fail at reintegration with family and society. The purpose of the investigation was to learn if substance abuse treatment and obtaining an education in the form of a General Equivalency Diploma (GED) would help the ex-offender avoid further recidivating The investigator was also interested in learning if trust played a vital role in gaining a GED and completion of substance abuse treatment with reintegration of the family for the …

Peace At Last Or Just A Piece Of Paper? Assessing The Utilization Of Civil Protection Orders And Reported Violations, Jennifer Medel

Dissertations

Over the past 50 years, attention to domestic violence as a social problem has grown substantially. With this heightened interest, remedies available to survivors have evolved in both scope and access. One popular avenue of help-seeking concerns civil protection orders (POs), which attempt to prevent subsequent abuse by setting conditions that regulate future interaction between abusers and survivors. Abusers, unfortunately, often violate POs with estimates of cases with violations ranging from 40 to 60%. Relatively little research, however, has examined the nature and determinants of PO violations using court records.

This dissertation addresses these little-studied issues by exploring variations in …

A Spectroscopic And Photometric Survey Of The W4 Hii Region And Its Young Stellar Population, Matt Wentzel-Long

Dissertations

The W4 HII region is home to a large number of O and B-type stars as well as the young open cluster IC 1805. OB-type produce intense photoionizing radiation and stellar winds that can induce star formation in surrounding molecular clouds and sometimes carve out large regions of decreased particle density called superbubbles. During the star formation process, young stellar objects (YSOs) are initially surrounded by circumstellar disks made of gas and dust which naturally dissipate after several million years. The dissipation of the disk is thought to occur for a variety of reasons, including photoevaporation by the encompassed protostar …

Automated Medication Dispensing Cabinet And Medication Errors, Marie Walsh

Dissertations

The number of deaths due to medical errors in hospitals ranges from 44,000 to 98,000 yearly. More than 7,000 of these deaths have taken place due to medication errors. This project evaluated the implementation of an automated medication dispensing cabinet or PYXIS machine in a 25-bed upper Midwestern critical access hospital. Lewin's stage theory of organizational change and Roger's diffusion of innovations theory supported the project. Nursing staff members were asked to complete an anonymous, qualitative survey approximately 1 month after the implementation of the PYXIS and again 1 year later. Questions were focused on the device and its use …

Nutritional Management Of The Extremely Low Birth Weight Infant: An Evidence Based Clinical Practice Guideline, Dana Lunde

Dissertations

Premature birth has risen steadily over the last decade resulting in an increased number of infants needing neonatal intensive care. The demand for neonatal intensive care has lead to many improvements in the delivery of such care with an increase in the survival of the smallest and most premature infants. However, most of these infants are being discharged from neonatal intensive care units (NICU) with severe extrauterine growth restriction (EUGR). Extremely low birth weight (ELBW) infants born at 23-27 weeks gestation and who have a weight of less than 1,000 grams are at the highest risk for EUGR because of …

The Experience Of Early Mobility After One Week Of Hospital-Acquired Deconditioning, Lila S. Moersch

Dissertations

Abstract

Older adults who are hospitalized spend most of their time in bed. Prolonged bed rest and immobility in older adults may result in deconditioning of the muscles, leading to a loss of muscle mass and strength. The loss of muscle mass results in weakness and reduced physiological functioning post-hospital discharge. Immobility is especially problematic in older adults who naturally lose muscle mass and strength due to the aging process. Older adults who experience weakness post-hospital discharge face challenges with mobility. The purpose of this study was to describe the early mobility experiences of adults who are 60 years old …

Help Seeking For Mental Health Problems In Mental Health Counselors: Prevalence, Barriers, And Predictors, Carol A. Miller

Dissertations

This study surveyed a sample of 255 mental health counselors in the United States and used descriptive statistics, chi-square tests, one-way ANOVA, and logistic regression analysis to investigate the prevalence of mental health problems and help seeking, the perceived barriers to, and predictors of help seeking for mental health problems among mental health counselors. In this sample, 62.6% (n = 159) reported they had experienced a mental health problem during the time since licensure. Of those, 13.2% (n = 21) reported they had not received treatment. “Handling the problem on my own” was the most cited barrier to help seeking, …

A Mixed Methods Examination Of Generational Faculty Perceptions When Developing Online Courses, Jelena Fleming

Dissertations

As technology continues to change rapidly, online learning altered higher education. As a result, instructional designers and instructional technologists became more critical in supporting faculty in online course design. Transitioning courses to the online environment created external barriers, such as no training and support, primarily for faculty who never taught online. Instructional designers and instructional technologists helped address external barriers among full-time and adjunct faculty and provided a positive online course development experience. Therefore, the researcher conducted a mixed-methods examination of generational faculty perceptions experienced during online course development at a small Midwestern institution. The researcher investigated a difference between …

Stochastic Delay Differential Equations With Applications In Ecology And Epidemics, Hebatallah Jamil Alsakaji

Dissertations

Mathematical modeling with delay differential equations (DDEs) is widely used for analysis and predictions in various areas of life sciences, such as population dynamics, epidemiology, immunology, physiology, and neural networks. The memory or time-delays, in these models, are related to the duration of certain hidden processes like the stages of the life cycle, the time between infection of a cell and the production of new viruses, the duration of the infectious period, the immune period, and so on. In ordinary differential equations (ODEs), the unknown state and its derivatives are evaluated at the same time instant. In DDEs, however, the …

A Quantitative Study Of Collaborative Theories Of Action, Teacher Collective Efficacy, And The Behaviors Of Student Self-Directedness, Melissa Ann Huff

Dissertations

This quantitative study was conducted to investigate the relationships among teacher collective efficacy, espoused theories of collaboration, collaborative theories in use, the gap between these theories, and student self-directedness. Costa and Kallick (2014) and Tough (2016) suggested student success is more than just academic. Frey, Hattie, and Fisher (2018) indicated student success is achieved when students develop a self-directed disposition. Based on the historical work of Argyris, Putnam, and Smith (1987), establishing the difference between espoused theories and theories in use, espoused theories of collaboration, collaborative theories in use, and the gap between these theories of action were investigated. The …

Racial Battle Fatigue And Black Male Higher Education Administrators, Joshua Walehwa

Dissertations

Racial Battle Fatigue was first coined by Dr. William A. Smith as a theory describing the burnout of African Americans in higher education institutions. While much of the current research focuses on the faculty and student experiences, in various formats, this provides an autoethnography capturing the various phases of a Black Male higher education administrators experience with experiencing and coping through Racial Battle Fatigue. The belief behind this approach focuses on the value of storytelling and autoethnography in particular in research, the interconnected nature of life experiences that impact professional life as well as the reverse, and a call to …
