Mathematical Knowledge For Teaching In Co-Teachers At The Post-Secondary Level: A Cognitive And Enacted Approach, Lida Marie Lavelle Bentz

Dissertations

Mathematical Knowledge for Teaching (MKT), the knowledge used by a teacher to teach mathematics, has often been examined as a cognitive construct in K-6 teachers, but little research exists examining MKT in the post-secondary teaching context. Schoenfeld (2020) extended the definition of knowledge and thus MKT to include tacit and explicit perceptions. In doing so, Schoenfeld created the terms "big K" mKt and "little k" mkt, where mKt refers to the tacit and explicit perceptions used by a teacher to teach mathematics and mkt includes the teacher's understanding used in teaching mathematics (similar to cognitive MKT). Building from Schoenfeld’s conceptualization …

Examining The Effectiveness Of Virtual Instruction For Medication Administration Skill Acquisition In Prelicensure Nursing Students, Jenna E. Davis

Dissertations

A large number of men die by suicide every year, and many men struggle with mental health concerns. Various components of masculinities can serve as barriers that dissuade men from seeking treatment for these concerns. Man Therapy is a novel approach that attempts to better engage men with professional psychological …

Expanding The Conceptualization And Applied Role Of Shame, Nathaniel Michael Burrow

Dissertations

Prior research has shown shame to be a key component of a variety of mental health issues, symptoms, and disorders; however, a growing body of research also found it to be integral in the process of seeking to atone, ameliorate, or repair a prior transgression. This study sought to further explore what factors influenced this process. By utilizing a posttest-only control group experimental design and the Gausel and Leach (2011) model as a framework, this study was able to operationalize and investigate the role shame had in motivating a prosocial versus self-defensive response. Additionally, this study advanced this model by …

Stealth Dyslexia: Cognitive And Achievement Profiles Of Gifted Students With Dyslexia, Anne Hardy Boris

Dissertations

Identifying students who are gifted with dyslexia (GWD) has presented a host of challenges to practitioners in school and clinic settings because these individuals possess both qualities of giftedness and learning difficulties, yet do not ‘fit’ in either category. The term “stealth dyslexia” was coined to indicate the presence of high abilities that may mask dyslexia traits, complicate diagnostic accuracy, and allow individuals to compensate for their weaknesses. The masking of reading difficulties can cause dyslexia to remain undetected in gifted children for a prolonged period of time which may leave them prone to academic disengagement. The present study provided …

Comparing Collegiate Coaches’ And Players’ Perceptions Of The Coaches’ Multicultural Competence, Lee Arakawa

Dissertations

The coaching effectiveness model developed by Horn (2008) describes cultural context as a backdrop that forms beliefs, perceptions, and behaviors displayed by sport coaches. Sue et al.’s (1992) multicultural competencies model stresses the value of awareness, knowledge, and skills used in all service fields to strengthen cross-cultural relationships. Therefore, multicultural competence has been identified from these models as a critical component of effective sport coaching. Despite the growing importance of multicultural competencies expressed by, and for, sport coaches (Mesquita et al., 2011; Santos et al., 2010), there remains limited understanding of how coaches obtain and apply multiculturally competent behaviors and …

Common withdrawal symptoms include experiences of nausea, muscle pain, stomach and headaches, shakiness, restlessness, anxiety, and agitation. Rarer, but more severe, withdrawal symptoms can include hallucinations, seizures, and delirium tremens. Pharmacologic treatment of withdrawal symptoms is the primary, and often only, approach to intervention. The current study examined the incremental efficacy of adding a psychotherapeutic program based in Acceptance and Commitment Therapy (ACT) for individuals struggling with withdrawal during alcohol detoxification in a residential rehabilitation center. This study compared the standard of care, medication management, which was treatment as usual (TAU) at …

Peridynamic Modeling Of Crack Propagation In Brittle Materials With Electromechanical Coupling, Semsi Coskun

Dissertations

The bond-based peridynamics (BB-PD) is a widely used peridynamic model in the literature. Despite Poisson's ratio restriction, it still serves as a powerful tool to solve challenging engineering problems with a relatively cheap computational cost. Consider the Poisson ratio of the material does not deviate from the ones that BB-PD can model. In that case, it becomes advantageous to use the BB-PD compared to other PD models in terms of computational cost and simplicity. However, the BB-PD suffers from the so-called surface or skin effect where the material response at boundaries becomes softer than the bulk material points. As a …

Masculinity Ideology As A Moderator On The Effects Of Lethal Means Counseling And Distribution Of Cable Locks On Firearm Storage Practices Among National Guard Personnel, Samantha E. Daruwala

Dissertations

Safer firearm storage practices, which may reduce suicide risk, can be promoted by lethal means counseling (LMC). A recent trial found that providing a single LMC session or distributing cable locks can lead to sustained changes in firearm storage practices within a sample of firearm-owning National Guard personnel (Anestis et al., 2021). An important next step is to consider if the intervention effects may differ based on participant characteristics. One particularly relevant sociodemographic characteristic to consider is traditional masculine norms, which are evident in the military and firearm cultures and associated with several negative outcomes. The current study evaluated if …

Examining P3 And N2 Amplitudes Following Social Exclusion And Provocation In College Students With High And Low Narcissistic Traits, Kathleen Ramsey

Dissertations

Adults with narcissistic traits are prone to reacting aggressively following provocation due to elevations in emotional reactivity and perceived threat to their grandiose self-views. Prior studies have examined event-related potentials (ERPs) measures in college students with narcissistic traits in the context of risky decision making and facial emotion processing; however, no known studies have examined how those with narcissistic traits react to rejection and provocation at the neurophysiological level during an externally valid social rejection task (i.e., Cyberball). For the purposes of this study, it was predicted that participants with higher levels of narcissistic traits (both total narcissism and grandiose …

Using Nudges To Increase Engagement With Suicide Prevention Resources In An Online Sample Of United State Military Veterans, Brian W. Bauer

Dissertations

Suicide rates have continually increased from 1999 to 2019 in the United States, with populations such as military Veterans showing substantially higher suicide death and attempt rates than civilians. Behavioral economics researchers have demonstrated that people regularly make decisions that are not aligned with their own self-interests (i.e., irrational decisions). These irrational decisions often stem from humans having bounded rationality (i.e., limited computational power), which produce reliable cognitive biases that occur outside of people’s awareness and influence the decisions they make. There are many important decisions leading up to a suicide attempt (e.g., whether to engage with suicide prevention resources), …

The Covid-19 Experience: An Intensive Care Nursing Perspective, Adrianna L. Watson

Dissertations

Frontline healthcare workers struggled to care for the patient after patient with limited knowledge of pathophysiology, risk of contagion, and resources. As the waves of patients became increasingly critical, the task of everyday human connection and care, as well as extraordinary life-saving measures, fell upon the shoulders of intensive care nurses. Little is known about how these nurses understand their experiences caring for patients with the novel coronavirus, or how their …

The Effect Of A Specific Teaching Intervention On The Perceptions Of Self-Regulation In Undergraduate Baccalaureate Nursing Students In Saudi Arabia, Zahra Alnasser

Dissertations

Self-regulation is an important aspect of learning. Students who are capable of self-regulation, plan self-monitoring at different points during the process of knowledge acquisition to increase their likelihood of success and knowledge retention. Using self-monitoring, self-instruction, and self-evaluation processes enables students to become decisive in their learning. Previous studies have confirmed that self-regulated students have great success in college courses, and provided evidence for the positive benefits of self-regulation interventions. Still, nursing education lacks empirical research that focuses on self-regulation quality. The current study explored individual differences in third and fourth-year nursing students' perceptions of self-regulation profiles in Saudi Arabia …

Career Mobility Among Immigrant Registered Nurses In Canada: Experiences Of Caribbean Women, Enid M. Collins

Dissertations

Since the late 1950s, the Canadian nursing workforce especially during periods of nursing shortage has added to its numbers through immigration. Changes in immigration laws since the 1960s have opened doors for increased numbers of immigrants from Asia, Africa, and the Caribbean coming to work in Canada. This qualitative research study investigated the experiences of immigrant women from the Caribbean who are registered nurses (RNs) in Canada. There has been no previously published studies that documented experiences of immigrant women of colour related to career mobility in nursing.

Exploring The Impact Of Simulation Anxiety On Clinical Judgment For Nursing Students, Janet M. Reed

Dissertations

Research literature provides evidence that new graduate nurses are often deficient in clinical judgment (CJ). One way to increase CJ is by using simulations. However, the literature is replete with descriptions of the high anxiety that simulation triggers. It is not currently known how anxiety in simulation affects clinical judgment for undergraduate nursing students. Therefore, the purpose of this study was to explore the effect of different types of anxiety on the clinical judgment of undergraduate nursing students in simulation.

This research project used a one-group repeated measures quantitative design to answer the research questions using the conceptual framework of …

Retention of nurses is a major concern for the profession, especially in light of the nursing shortage; specifically, new graduate nurses are particularly susceptible to this phenomenon. While there are many causes for turnover and attrition within the profession, nurse burnout has been indicated as a central cause. As such, researchers have dedicated much energy and focus into pinpointing approaches that may mitigate the effects of burnout, turning to grit as a possible solution. However, research on grit in nursing is limited, with even less being included on how this trait can be developed. Nevertheless, researchers agree that strategies for …

The Effect Of Implementing A Cultural Change Toolkit On Burnout Among Emergency Nurses, Isabella Nassif

Dissertations

Burnout continues to be a significant problem that negatively affects healthcare providers, especially nursing staff in acute care settings, such as the emergency department. Burnout is the state and experience of continued and prolonged exposure to depersonalization, loss of motivation, emotional exhaustion, and reduced personal accomplishment (Harris & Griffin, 2015; Hutson Hendy, 2016). Burnout is manifested through depersonalization, having a loss of compassion and concern, a decreased sense of personal accomplishment from work, and emotional exhaustion from feeling emotionally drained (Li et al., 2018). The literature on burnout lacks a systemic analysis of evidence-based interventions that can mitigate burnout among …

Perceptions Of Instructor Caring Behaviors Between English As A Second Language And Non-English As A Second Language Nursing Students, John C. Dike

Dissertations

English as a second language (ESL) nursing students have a significantly higher attrition rate and lower National Council Licensure Examination (NCLEX) pass rate than their non-ESL counterparts. Instructor caring behaviors (ICBs) are the ways nursing instructors treat students with respect, taking care to avoid prejudices, stereotyping, and judgments in the teaching-learning process which present prelicensure faculty to grapple with the challenge of effectively meeting the learning needs of both ESL and non-ESL students. The purpose of this cross-sectional, comparative study, guided by Watson's theory of human caring, was to explore the differences in perceptions of ICBs between ESL and non-ESL …

Influences Of 12-Hour Shifts On Unhealthy Eating Habits Of Acute Care Nurses, Ruth Sawdy

Dissertations

Shift work is a necessary part of a nurses' work schedule to patients who need 24 hours of continuous care. Eating habits of nurses are influenced by working long hours, not having adequate time to take a meal break, and not having access to healthy food choices which can cause stress and exhaustion and results in weight gain and obesity. The purpose of this quantitative logistic regression analysis, guided by the health belief model and the theory of planned behavior, was to determine if there was a relationship between shift work and the unhealthy eating habits/obesity rates of acute care …

Choices Related To Maximizing Quality Of Life At End Of Life, Theresa Lynn

Dissertations

Humans, including those residing in the United States, can live in denial of their own mortality. Because of this, futile care is sometimes provided, often at great monetary expense and for little or no return in terms of quality or length of life. At least two opportunities exist for making choices regarding care at the end of life in the U.S.: completing advance directives and choosing hospice care.

An Exploratory Multiple Case Study Of Discipline Practices In A Major Metropolitan Public School District: A Look Into The School To Prison Pipeline, Neil French, Kristin Calvert-French, Phyllis Jackson, Erin King

Dissertations

The school to prison pipeline is a phenomenon fed by exclusionary discipline practices that increase the likelihood that a student will have an interaction with the juvenile or criminal justice system at some time in their life; this phenomenon disproportionately affects Black students. Understanding the problem is key to slowing down the school to prison pipeline. This study of a school district in Missouri explores questions about how interpersonal relationships, implicit bias awareness, and school policies influence the learning environment, and how those factors relate to school discipline, which ultimately can lead to the school to prison pipeline. Drawing data …

Relationship Of Leader-Member Exchange On Role Stress And Burnout: A Public Accounting Perspective, Sammie Parsley

Dissertations

An issue that concerns public accounting firms, both large and small, is that of employee burnout within the workplace. As a service-oriented industry, accommodating client needs is pivotal to long-term success. With that in mind, meeting client demands often means accountants must work long and strenuous hours, an attribute inherent to the industry. Consequently, public accounting firms often find themselves struggling with voluntary turnover as a result of burnout and opportunity for increased financial incentives elsewhere. The busy season in public accounting can be especially difficult, as accountants can find themselves working very long hours for weeks on end. This …
