Exploring The Impact Of Negative Ewom On Hotel Booking Intention Through The Lens Of Attribution Theory And The Moderating Role Of Recovery Justice, Antonio Jose Ogaz-Muñoz
Exploring The Impact Of Negative Ewom On Hotel Booking Intention Through The Lens Of Attribution Theory And The Moderating Role Of Recovery Justice, Antonio Jose Ogaz-Muñoz
Electronic Theses and Dissertations
Negative electronic word-of-mouth (EWOM) has emerged as a critical factor influencing customer behavior, particularly in the hospitality industry. Despite extensive research grounded in failure attributions and service recovery theories, few studies examine the combined impact of failure attribution and recovery justice on hotel booking intentions. Using a 2x2x2x2 between-subjects experimental design with 373 responses, this research investigates how customers' perceptions of failure attribution influence their booking intention after exposure to negative EWOM, and if perceived recovery justice can mitigate the negative effects of these attributions. Results show that booking intention declined most when reviews framed the failure as hotel-caused and …

New results are accompanied by proofs and unified methods using tools drawn from harmonic analysis, functional analysis, point set topology, the theory of charges (finitely additive measures), and mathematical logic. The central contribution of this work lies not only in its results, but in its exposition, which presents a coherent framework intended to bridge advanced research and graduate-level study, to further developments in related areas.
Do Algal Endosymbiont Communities In Coral Outplants Change Over Time? A Spatio-Temporal Analysis Of Algal Symbionts In A South Florida Coral Restoration Experiment, Milena Nesic
Electronic Theses and Dissertations
Increasingly frequent marine heatwaves and bleaching events threaten the persistence of corals on Florida’s Reefs. Active restoration through outplanting is being implemented across multiple species and regions, yet its effectiveness under rising thermal stress remains uncertain. We analyzed Symbiodiniaceae ITS2 sequence data from outplants of three coral species, Pseudodiploria clivosa, Montastraea cavernosa, and Orbicella faveolata, sampled before (2023) and after (2024) a mass bleaching event. Multivariate analyses revealed species-specific yet regionally divergent trends: southern restoration regions exhibited pronounced shifts toward thermotolerant Durusdinium, while northern regions remained comparatively stable. Although fine-scale ITS2 variation contributed to community heterogeneity, genus-level shifts …

This study focuses on the Brady Mountain area within the Benton Uplift, the orogenic core of the Ouachita Mountains in western Arkansas. The region is comprised of numerous ridges trending nearly east-west and are for the most part densely …
Floodplain Lake Hydrodynamic And Morphodynamic Connections Through Hydraulic Modeling Along The Pee Dee River, Sc, Charles Cj Mina
Floodplain Lake Hydrodynamic And Morphodynamic Connections Through Hydraulic Modeling Along The Pee Dee River, Sc, Charles Cj Mina
Electronic Theses and Dissertations
Rivers have been essential in the success of humankind. This reliance has created a vested interest in studying the rivers' environmental history through using floodplain deposits, with the assumption that coarser sediments correlate to higher discharge floods. However, shifting hydrological connectivity and hydrodynamics can complicate this correlation in primary repositories of flood deposits, oxbow lakes, by altering the texture of sediments delivered to them. Studying these complications is essential for quantifying paleoflood magnitude using the sediment record, but has been difficult, as the currently used index of hydrological connectivity relies on water stage, which does not reflect the sediment flux …

The Food Truck: A Multi-Product Newsvendor With Expectile Risk, Sekyiwaah Nuamah
The Food Truck: A Multi-Product Newsvendor With Expectile Risk, Sekyiwaah Nuamah
Electronic Theses and Dissertations
The Newsvendor Problem is a fundamental model in Operation Research and Supply Chain Management used to determine the optimal order quantity under uncertain demand to minimize expected costs.
This research extends the classical Newsvendor problem to a multi--product setting, addressing the risk of asymmetric cost structures faced by a food truck. This thesis introduces expectile risk measures to quantify and manage uncertainty in demand, moving beyond traditional risk metrics. To evaluate the impact of expectile-based decision-making, we analyze three types of demand distributions--simple, symmetric, and skewed. For skewed distributions, we apply linear spline inverse interpolation to derive expectile values from …
Deep Learning With Kalman Filter, Rexford Julius Quaye
Deep Learning With Kalman Filter, Rexford Julius Quaye
Electronic Theses and Dissertations
This thesis presents an extension of the Kalman filter to handle nonlinear and non-Gaussian systems. The standard Kalman filter is optimal under Gaussian assumptions but struggles with more complex noise models. This work introduces a novel loss function based on the Mahalanobis distance, which incorporates the covariance structure of measurement errors, enabling the filter to adapt to non-Gaussian scenarios. The neural network framework is applied to predict the system’s process model, while retaining the classical Kalman measurement update. The proposed methodology is demonstrated through examples of car position and rocket altitude tracking. The results show that the new approach performs …

Electronic Theses and Dissertations
The purpose of this qualitative narrative inquiry was to examine how educators in high-performing districts that met or exceeded state targets for Individuals with Disabilities Education Act (IDEA) post-school outcomes implemented and sustained evidence-based practices to support successful transitions for students with disabilities. Despite decades of legislative mandates and educational reforms, students with disabilities continue to experience disproportionately lower rates of employment, postsecondary education, and independent living compared to their peers. This study sought to identify not only which practices are effective but also how they are operationalized and maintained within school systems.
Two Tennessee districts identified by exemplary performance …
“War Is God” And “Unguessed Kinships”: Blood Meridian And Cormac Mccarthy’S “Border Tetralogy”, Seth Reeves
“War Is God” And “Unguessed Kinships”: Blood Meridian And Cormac Mccarthy’S “Border Tetralogy”, Seth Reeves
Electronic Theses and Dissertations
This thesis applies the metaphysics of philosopher Gilles Deleuze to Cormac McCarthy’s novel Blood Meridian, arguing that the novel initiates a thread of immanent subjectivity that unfolds throughout the Border Trilogy that follows it. Against a hierarchical metaphysics of transcendence, specifically an inverted Platonic Idealism, Blood Meridian dramatizes an immanent world of “optical democracy,” a prose style that levels the human and nonhuman and eludes subject and object categories. The kid’s autonomy from Judge Holden’s violent domination marks the truncated beginning of a Deleuzian subjectivity of becoming-other and immanent kinship. This incomplete gesture continues in the Border Trilogy, where …

Mass Spectrometry- And Genomic-Based Characterization Of Novel Glycosphingolipid-Producing Bacteria And Their Glycosyltransferases, Tahir Ali
Electronic Theses and Dissertations
Glycosphingolipids (GSLs) are a type of membrane-lipids commonly found in eukaryotes, as well as in bacteria from the order Sphingomonadales. In these bacteria, GSLs replace lipopolysaccharides as key structural and functional components of the outer membrane. These molecules play a crucial role in maintaining membrane integrity and helping bacteria adapt to environmental stresses. Additionally, they hold significant potential in biomedical research due to their ability to modulate the immune response through interactions with the CD1d receptor. Despite their important biological and biomedical roles, the diversity and biosynthesis of bacterial GSLs are far less understood compared to their eukaryotic counterparts. In …
Essays On Corporate Finance And Dark Pool Trading, Sarath Valsalan
Essays On Corporate Finance And Dark Pool Trading, Sarath Valsalan
Electronic Theses and Dissertations
In the first essay, we analyze how dark pool trading changes surrounding one of the largest corporate informational events, mergers and acquisitions. Alfarhoud, Bowe, and Zhang (2021) and Ye and Zhu (2020) suggest that the ability to hide trading is most valuable when the cost of information leakage is high. Since recent studies (e.g. Brolley, 2020; Ye and Zhu, 2020) find detrimental effects of dark pool trading on market quality, we expect that trading surrounding mergers and acquisitions will be opportunistic. We find that the share of dark pool trading rises significantly prior to an announcement compared to trading on …

This study highlights Samaroo’s approaches to melodic and rhythmic development, thematic expansion, orchestration, and textural variation. “Pan in A Minor” retains much of Kitchener’s original material while introducing structural expansion, whereas “The …
Típica Style Vs. Latin Jazz: A Comparison Of Traditional Salsa Piano Accompaniment And Latin Jazz Comping, Victorino C. Perez
Típica Style Vs. Latin Jazz: A Comparison Of Traditional Salsa Piano Accompaniment And Latin Jazz Comping, Victorino C. Perez
Electronic Theses and Dissertations
Salsa is a popular Latin American musical genre that combines dance and vocal music with a unique rhythmic style that draws influences from jazz and African rhythms. Salsa shares characteristics with Latin jazz. Traditional salsa, or típica style, features traditional tonal harmonies with few alterations, whereas Latin jazz typically employs complex harmonies including tritone substitutions, chord extensions, and chords with extensions and alterations. The primary argument of this research is that Latin jazz pianists maintain the functions of the traditional salsa while infusing it with jazz harmonic, rhythmic, and textural elements. This thesis compares accompanying (“comping”) traits, including form, harmony, …

Robotic Monitoring System For Complex Aquatic Environments, William Fairman
Electronic Theses and Dissertations
Persistent monitoring in an aquatic environment is critical in many scientific and industrial applications. In-situ sensors that record water quality metrics, like dissolved oxygen, are essential in many aquaculture applications. Existing monitoring solutions can be cost prohibitive, difficult to maintain, and are typically deployed in fixed locations. This limits the usefulness of such systems in complex aquatic environments like coastal zones or pond aquaculture farms where bodies of water can be isolated from each other. In this dissertation research, an autonomous data collection framework is proposed to provide low-cost water quality monitoring through the combination of a variety of sensors …
