Understanding Food Waste Behavior And Ways To Influence Positive Change And Waste Reduction, David Hubinger

Dissertations

Environmental problems such as pollution, climate change, and food waste can be influenced by social attitudes and human behavior. Solutions to address environmental problems involve a series of actions by society and individuals, which can prove difficult to implement because changes induced by pro-environmental behavior often cannot be seen immediately by individuals or may not generate appreciable, direct benefits. The purposes of the quantitative correlational study are threefold: first, examine environmental attitudes, subjective norms, perceived behavioral control, and overall behavioral intent to reduce household consumer food waste among a sample of consumers; second, to examine the extent to which select …

Black Beyond Measure: An Antideficit Exploration Of Cultural Capital Within A National Society Of Black Engineers (Nsbe) Chapter At A Predominantly White Institution (Pwi), Rhonda Harley

Dissertations

Historically, Black students have been excluded from Predominately White institutions (PWI) longer than welcomed to attend and matriculate (Harper et al., 2009). Due to this lack of inclusion, African American students' educational experiences often center on academic disparities, inequality of opportunity, and under-preparedness in career planning within the American education system. While there has been a fair amount of research on the lack of representation of Black students in the engineering disciplines, the heavy focus on quantitative data offers little insight into the unique ways students succeed and overcome institutional and systemic barriers in pursuit of their degree. Undergraduate experiences, …

School Administrator Preparation In Special Education: A Cross-Case Analysis, Emily Ruiz

Dissertations

Special education has been part of public education for 46 years and has evolved considerably in that time. Despite improvements made in special education law, there remains a disconnect between law and current practices. Several studies suggest this disconnect is associated with administrators’ insufficient preparation for supporting special education in their schools.

This study utilized an explanatory sequential design to study Southern California school principals’ special education preparation. During the first phase of the study, the researcher emailed surveys to administrators who were selected using a stratified random sampling strategy. Unfortunately, the response rate was too low to employ the …

Constructing Roles And Discourse: Presidential Speech And European Union Accession In The Former Yugoslavia, 2000-2021, John Horner

Dissertations

Yugoslavia’s dissolution in the 1990s resulted in seven distinct nation-states vying for functional institutions, ethno-nationalistic coalescence, and external validation. To this end the European Union (EU) offered a pathway to nation-state building and membership via democratization, economic liberalization, and legal and civil improvements. However, to date only Slovenia (2004) and Croatia (2013) are EU member-states. Montenegro, North Macedonia, and Serbia are candidate countries. Bosnia and Herzegovina and Kosovo are potential candidates. What are the incentives for Western Balkan countries to reform and join the EU? Were motivations driven by rational, economic benefits of membership, or was the impetus identity-oriented to …

Examining Workplace Elearning Programs Using Persuasive Learning Design: A Hermeneutic Phenomenological Study, David Akanbi

Dissertations

eLearning platforms have become the primary method for employee development in organizations (Dellagiacoma et al., 2020). This shift from the in-person approach has increased resources and budget allocation for authoring software applications needed to develop interactive eLearning programs (Kshirsagar et al., 2020). Despite spending a considerable amount of money on eLearning authoring software, there are concerns that most workplace eLearning programs do not achieve the desired outcomes (Jones, 2016; Patel, 2017; Sidhu, 2019). Although studies show that eLearning programs have effectively enhanced learning transfer, the same studies suggest that employees do not retain information in some eLearning programs (Dellagiacoma et …

Characterization Of Sea Level Changes Along The Louisiana/Florida Shelf Using High Frequency (Hf) Radar Data And Sea Level Measurements, Uchenna Nwankwo

Dissertations

In this dissertation, three sea level studies in the Mississippi Bight (MSB) have been conducted. The first is an investigation into why VDatum, the vertical datum transformation tool of NOAA, has large errors in the western side of the MSB.

Does Optic Flow Provide Information About Actions?, Hannah Masoner

Dissertations

Optic flow, the pattern of light generated in the visual field by motion of objects and the observer’s body, serves as information that underwrites perception of events, actions and affordances. This visual pattern informs the observer about their own actions in relation to their surroundings, as well as those of others. This study explored the limits of action detection for others as well as the role of optic flow. First-person videos were created using camera recordings of the actor’s perspective as they performed various movements (jumping jacks, jumping, squatting, sitting, etc.). In three experiments participants attempted to detect the action …

The Influence Of Word Pair Associative Direction On Judgment Of Learning Reactivity, Nicholas Maxwell

Dissertations

Judgments of learning (JOLs) are commonly used by researchers to assess whether individuals can accurately predict later memory performance. While the JOL literature has generally operated under the assumption that providing judgments at study does not affect the learning process, recent studies have shown a reactivity effect in which memory differs between participants who do and do not make JOLs at study. The effects of providing JOLs on memory have been mixed: Some studies report memory improvements (i.e., positive reactivity), while others report memory costs (i.e., negative reactivity). Additionally, little work has evaluated the effects of associative direction (i.e., credit-card …

Implementation Of Remote Patient Monitoring To Improve Medication Adherence And Efficacy In Patients With Asthma And Chronic Obstructive Pulmonary Disease: A Quality Improvement Project, Barbara A. Werner

Dissertations

Asthma and chronic obstructive pulmonary disease (COPD) are long-term respiratory diseases that can adversely affect an individual's quality of life and inflict financial strain on the patient, family, and healthcare system (Kocks et al., 2018). Adherence to prescribed inhaler medication is an integral component of effective disease management. Remote patient monitoring may serve as an effective means to proactively measure adherence with inhaled medications to improve respiratory health outcomes and decrease avoidable healthcare utilization (George & Bender, 2019). An inobtrusive device attaches to the metered dose inhaler to passively monitor the use and electronically transmit the information to a digital …

Barcode Medication Administration In The Emergency Department To Mitigate Medication Errors, Holly E. Gauthier-Wetzel

Dissertations

Electronic health record systems (EHRs) have been adopted in healthcare facilities to unify the workflow process of healthcare professionals. Studies have demonstrated the addition of barcode medication administration (BCMA) software technology within the EHR has decreased medication errors within hospitals and long-term care facilities. However, limited research has been conducted to establish whether using BCMA in outpatient areas has had an influence on medication error rates. Literature reveals that many facilities have not adopted BCMA in outpatient areas. The purpose of this study was to investigate whether medication errors were mitigated after BCMA was implemented in the emergency department (ED). …

Youth Organizing From Within: A Case Study Of A District Youth Equity Council, Amy Elizabeth Nelson

Dissertations

The experiences of Black, indigenous, and person of color (BIPOC) youth in our school systems often share a common thread of having to navigate deficit thinking, institutionalized racism, marginalization, and discrimination (Hammond, 2015; Ladson-Billings, 2016; Roy et al., 2019). While youth organizing has emerged as a potential counter to deficit narratives, it is rarely seen in school settings (Arthurs, 2018; Kirshner & Ginwright, 2012; Roderick et al., 2020; Roy et al., 2019). Using critical race theory as a framework, this case study examined a sample of BIPOC middle and high school students serving on a district Youth Equity Council, their …

An Efficient Computational Method For Causal Inference In High-Dimensional Data: Neighborhood-Based Cross Fitting, Oluwagbenga David Agboola

Dissertations

High-dimensional data are increasingly popular in various physical science and social science disciplines. This study proposed a new computationally efficient sample splitting method called Neighborhood-Based Cross Fitting (NBCF) for double machine learning in causal inference on high-dimensional data. A common existing approach of repeatedly splitting data was suggested to address the overfitting problem in high-dimensional statistics, however it is computationally expensive. The proposed method deals well with the problem of post-selection bias in causal inference in the presence of high-dimensional confounders. Also, it provides an equivalent performance in unbiased estimation as repeated data splitting, which is suggested to expand the …

Bayesian Joint Modeling For Longitudinal Outcomes Of Exponential Families And Informative Time Points, Michael Safo Oduro

Dissertations

The benefits of longitudinal data in clinical research are immense, owing to the potential to detect phenomenon changes and trends over time. An avalanche of traditional methods exist for the analysis of this data kind, most of which are predicated on the assumption of fixed time design for study individuals. This assumption however, is not always tenable. Consider occurrences that can alter the time or visit profile of subjects in a clinical trial, such as adverse events. These may result in not just irregular visit times, but also unbalanced data on subject outcomes. Hence, one can consider visit times to …

Creating, Destroying And Preserving Coherence With Quantum Channels, Masaya Takahashi

Dissertations

Quantum coherence is a fundamental property of quantum systems that can be studied within the framework of a quantum resource theory. In chapter 2, we consider how much coherence can be either generated or destroyed on a bipartite system when the action is restricted to local unitary operations. For pure states, we find that the relative entropy of entanglement and the robustness of entanglement provide tight lower bounds on the amount of coherence that can be destroyed by local unitaries, as measured by the relative entropy and L1 measures of coherence, respectively. We then study the amount of bipartite pure …

Implementing Theory-Based Debriefing In The Clinical Learning Environment To Improve Teaching And Learning Outcomes, Adrienne Denise Wilk

Dissertations

For decades, the hallmark of nursing education has been experiential learning in a hands-on clinical environment (Kolb, 1984), allowing students to utilize clinical reasoning and decision-making skills and apply theoretical knowledge to patient encounters (Gubrud-Howe, 2020). To optimize student learning, nurse educators must develop skills to implement teaching methods that promote higher-level reasoning skills in students. One teaching method that is useful in the clinical setting and promotes higher-level reasoning is debriefing. While there were robust findings in the literature about debriefing simulated clinical experiences and the positive effect these had on students’ learning and reasoning (Cantrell, 2008; Dreifuerst, 2012; …
