Emotional Labor: An Affective-Commitment Perspective, Matthew J. Vosburg

Doctoral Dissertations

The emotional-labor literature asserts that individuals respond to emotion-display requirements, called display rules, with surface and deep acting. However, surface acting, but not deep acting, relates to deleterious occupational-health outcomes. Deep acting, therefore, is a strategy organizations should promote, should they wish to prioritize the well-being of their employees. Unfortunately, little research exists that clarifies the emotional-labor-choice process. The current study used the job demands-resources model and self-determination theory to hypothesize that affective organizational commitment would differentially moderate the relationship between display rules and the methods of emotional labor. To evaluate this study's hypotheses, 320 participants on an online survey …

The Role Of Video Game Play, Gender Roles, And Career Decision Self-Efficacy In Development Of Stem Career Interests & Motivation, Michael Saunders

Doctoral Dissertations

The gender wage gap, disadvantaging working women, continues to grow despite progress toward women’s rights and occupational equity. With the world economy prioritizing growth in technological industries, the underrepresentation of women in science, technology, engineering, and mathematics (STEM) fields perpetuates systemic gender inequity. Further, given traditional social gender roles, women and girls may be less likely than boys and men to pursue STEM careers. Though specialized programs seek to grow the number of girls and young women engaged in STEM-related education and prepare them for the growing demand for STEM laborers, these programs are regional, seasonal, and not widely available …

In Vivo And In Vitro Expression And Interaction Of The Mediator Kinase Module Subunits During Adipogenesis, Sree Lakshmi Venigalla

Doctoral Dissertations

Selective gene expression is crucial in maintaining the self-renewing and differential potential of stem cells. Especially differentiation process requires a constellation of proteins that regulate expression of genes necessary for differentiation towards a specific lineage. Adipogenesis is a process of formation of mature fat cells from precursor cells that is tightly regulated by a number of transcription factors and their cofactors. Dysregulation in the process often leads to metabolic disorders, which is common due to prevalence of obesity. Mediator is a large, evolutionarily conserved, multi-subunit protein complex that functions as a transcriptional coactivator that modulates gene expression by relaying signals …

Novel Methods For Determining Polymer Content And Polymer Degradation In Asphalt Binder, Roksana Hossain

Doctoral Dissertations

Styrene-butadiene-styrene (SBS) is the most common modifier used in asphalt binder modification because of its superior performance compared to some others that are used. SBS modified asphalt binder increases the rutting resistance and decreases the fatigue and thermal cracking susceptibility of asphalt pavement. However, SBS modified asphalt binder tends to separate and is subjected to thermal degradation during construction and aging degradation during its service life. As a result, quality control of SBS modified asphalt binder is needed, although no standard test method is available to quantify SBS degradation due to aging.

In this study, two methods for quantifying SBS …

The Morphology Of Layered Non-Woven Fabrics., Adel El-Hadidy

Mansoura Engineering Journal

The morphology of layered NW fabrics has been studied in terms of fabric thickness (tL), packing density coefficient (ØL), fabric hardness (HL), and energy-absorbed index (bL). All these terms are obtained when the fabric is subjected to compression. For multi-layer NW fabric, energy-absorbed index was found to increase as fabric hard ness decreases. The product of fabric hardness and compression energy index for all tested NW fabrics is constant, i.e. Hb = 435. Also it was found that as the no. of layers increase the multi-layered thick ness and/or mass per unit area is increase While the packing density coefficient. …

A Novel Numerical Method For Solving Fractional Diffusion-Wave And Nonlinear Fredholm And Volterra Integral Equations With Zero Absolute Error, Mutaz Mohammad, Alexandre Trounev, Mohammed Alshbool

All Works

In this work, a new numerical method for the fractional diffusion-wave equation and nonlinear Fredholm and Volterra integro-differential equations is proposed. The method is based on Euler wavelet approximation and matrix inversion of an M × M collocation points. The proposed equations are presented based on Caputo fractional derivative where we reduce the resulting system to a system of algebraic equations by implementing the Gaussian quadrature discretization. The reduced system is generated via the truncated Euler wavelet expansion. Several examples with known exact solutions have been solved with zero absolute error. This method is also applied to the Fredholm and …

The Role Of Trust In Advice Acceptance From Non-Human Actors, Rahul Banerjee

Dissertations and Theses Collection (Open Access)

Advancements in technology are now allowing non-human actors in the form of robot-advisors, driverless cars, medical assistants to perform increasingly complex tasks. While technological change is as old as civilization, these non-human actors can do novel tasks. One such task is that they provide advice which is a credence service (Dulleck, & Kerschbamer, 2006). Using a financial services context this thesis studies the role trust plays in advice acceptance.

Robo-advisors are rapidly replacing human financial advisors as the agent-provider for portfolio investment services. For centuries, it was the banker (human financial advisor) who was responsible for providing his investors with …

Let's Play A Story: Early Educators' Experience Implementing Story Drama With Support From Coaching, Amanda Wiehe Lopes

Graduate Doctoral Dissertations

While imaginative play, music, movement, and the visual arts are established components of the curriculum in early childhood education (ECE), teacher-guided story drama, or “improvised role play stimulated by a story” (Booth, 2005, p. 8), is an underutilized arts-based practice that supports children’s early literacy skills, creativity, and enjoyment of learning. There are numerous practitioner books and resources about the benefits of and strategies for how to incorporate storytelling, dramatic play, theater, and creative dramatics into the early learning environment (Bolton & Heathcote, 1999; Booth, 2005; V. Brown & Pleydell, 1999; Carleton, 2012), however, there is little research examining the …

The Activity Of Abstraction In Physical Chemistry Problem Solving And Instruction, Jessica M. Karch

Graduate Doctoral Dissertations

Productive problem solving, concept construction, and sense making occur through the core process of abstraction. Although the capacity for domain-general abstraction is developed at a young age, the role of abstraction in increasingly complex and disciplinary environments, such as those encountered in undergraduate STEM education, is not well understood. Undergraduate physical chemistry relies particularly heavily on abstraction because it uses many overlapping and imperfect mathematical models to represent and interpret phenomena occurring on multiple scales. To reconcile these models, extract meaning from them, and recognize when to apply them in problem solving requires processes of abstraction. This dissertation aims to …

Polarization Dynamics In Nonlinear Photonic Resonators, Saif A. Al Graiti

Theses

The global market demand for higher-bandwidth communication is increasing exponentially. Although optical networks provide high transmission speed using light to transmit signals, a bottleneck-inducing conversion is often needed to perform the processing of optical signals in the electrical domain. Such processing imposes a major barrier that would limit the high transmission speed of fiber-optic communications. This bottleneck conversion may be mitigated by extending signal-processing capabilities directly into the optical domain itself. Thus, I have studied the dynamics of optical polarization in a nonlinear photonic resonator to understand a new optical physical behavior to enhance the capabilities of optical signal processing. …

Examining The Tradeoffs Of Green Infrastructure For Stormwater Management: Ecosystem Services Vs. Environmental And Human Health Impacts, Ciara M. Heister

Theses

As green stormwater infrastructure (GI) practices become more widely implemented, it is important to develop a full understanding of both the positive and negative ways that GI practices may influence environmental and human health. Additionally, as climate change leads to shifts in precipitation patterns, it is necessary to understand how the resulting changes in stormwater runoff volume, soil moisture, and vegetation species composition will impact both biogeochemical cycling and the production of ecosystem services and disservices. The overall objective of this study was to compare green stormwater infrastructure practices by weighing the tradeoffs that exist between negative impacts such as …

Assessing The Degree Of Agreement Between Polarized And Unpolarized Densitometry In Offset Lithographic Applications, Devin J. Schneider

Theses

Automated color measurement systems have become significant components of offset lithographic printing presses for better process control and reduced job waste. In Europe, printers have broadly adopted polarized densitometry, which is uncommon in US standard operating procedures. It is recognized that some European press manufacturers provide automated color measurement instrumentation limited to polarized density readings. Introducing polarized densitometry into an environment where unpolarized densitometry is utilized can be problematic. The increasing significance of this issue has motivated print professionals to look for a solution. The present study applies the Bland-Altman method together with other statistical analyses to determine if a …

Marginalizing Over The Waveform Systematics Of Compact Binary Coalescence Models Using Rift, Aasim Zahoor Jan

Theses

As Einstein’s equations for binary compact object inspiral have only been approximately or intermittently solved by analytic or numerical methods, the models used to infer parameters of gravitational wave (GW) sources are subject to waveform modeling uncertainty. We illustrate these differences and then introduce a very efficient technique to marginalize over waveform uncertainties, relative to a prespecified sequence of waveform models. We also extend this technique to include dynamic weighting by calculating overlap of models with Numerical Relativity. Being based on RIFT, a very efficient parameter inference engine, our technique can directly account for any available models, including very accurate …

Investigating Expansion And Extinction In The Planetary Nebula Ngc 7027 With Hst, Paula M. Moraga Baez

Theses

Planetary nebulae are a late stage of the evolution of intermediate-mass (~1-8 solar mass) stars. A planetary nebula is formed after an asymptotic giant branch star's ejected mass becomes ionized by the stellar core, which is on its way to becoming a white dwarf. The shaping of planetary nebulae is slowly unveiled through studies of young and evolving nebulae such as NGC 7027. I have conducted an extensive analysis of the first-ever suite of contemporaneous panchromatic Hubble Space Telescope Wide Field Camera 3 (HST/WFC3) images of NGC 7027, extending from near-UV to near-IR. Extinction correction is performed successfully on several …

Housing And Urban Development Home Development And The Future Of The Industry: Case Study, Nolan J. Binkele

Construction Management

A HUD home is a 1-4 unit residential property acquired by HUD (Housing and Urban Development) as a result of a foreclosure action. These homes tend to be priced slightly below market value in order to regain past losses. The Department of Housing and Urban Development has developed a building code to classify manufactured homes as HUD. Although manufactured homes are typically sold to single property owners, I hypothesize that building them in a tract form can benefit a community by providing affordable, adequate housing for low income families and single families. I also hypothesize that HUD home development will …
