Wake Up America: Conceptualizing The Social Determinants Of Sleep, Nicole Eve Bray

Masters Theses

This paper is an attempt to understand racial, ethnic and gender disparities in sleep as a sociological problem. Public health and sociological researchers have looked at the connection between sleep disparities among minorities and the impact it has on health. However, they haven’t explained and applied the social structural factors that cause these disparities, as well as address how stress can serve as a moderator. In my investigation, I found that sleep troubles differ across race, ethnicity and gender. These differences relate to the distinguishable life situations of women and minorities in American society, such as stressful life circumstances that …

Evaluation Of A Cue Associated With Alternative Reinforcement To Mitigate Resurgence, Hayley Brown

Masters Theses

Treatment relapse due to the extinction of a previously reinforced alternative behavior is known as resurgence. Understanding the conditions under which resurgence is mitigated may be important for improving the maintenance of the effects of interventions. One method that has been found to effectively mitigate resurgence is pairing a cue or stimulus with alternative reinforcement and then continuing to present that cue when alternative reinforcement is terminated. Animal studies have found that cues must be paired with alternative reinforcement and target extinction to be effective. However, this finding has not yet been replicated with humans. Demonstration of a similar effect …

Behavioral Economic Factors In Collective Bargaining, Cristal Cardoso Sao Mateus Cardoso Sao Mateus

Masters Theses

The present study evaluated the effects of delay, stake, and hypothetical group size on labor valuation in the context of increasing and decreasing labor demand. Challenges in collective bargaining are associated with work stoppages, which can cause economic losses, lack of service, and worker stress. Participants were asked to value their labor given a set of conditions in two experiments. Participants in experiment 1 (n = 49) valued their labor in both increasing and decreasing demand context. Conversely, participants in experiment 2 (n = 139) valued their labor in only one of the contexts. Delay to changes, stake size, and …

Trends Of Autumn Phenology In Response To Environmental And Meteorological Variables, Meagan Renee Maguire

Masters Theses

Previous studies have identified that changes in plant phenology are most likely induced by climate variability. One such change is the end of season (EOS) for deciduous forests in the United States. In essence, the EOS represents the end of plant productivity for a given year; the phase in which plant dormancy is reached. However, our wealth of knowledge on plant phenology largely overlooks the phases that occur in autumn, especially the EOS, with many previous studies focusing on spring phenology. This study uses remote sensing MODIS aerial imagery data and historical meteorological data to analyze any relationships that may …

Nonlinear Finite Element Model For Functionally Graded Porous Circular/Annular Micro-Plates Under Thermal And Mechanical Load, Enrique Nava Munoz

Masters Theses

A nonlinear finite element model for micro circular/annular plates under thermal and mechanical loading is developed using a third order shear deformation theory. In the kinematic assumptions, the change of plate thickness is allowed and no transverse shear strains are considered on the top and bottom surfaces. A power-law distribution is utilized to account for variations of two constituents through the thickness of the plate. Three different types of porosity distributions are considered. The strain gradient effect in micro scale structures is considered using the modified couple stress theory. The dynamic version of the principle of virtual displacements is used …

Development Of S.T.E.A.M. Daises In Formal And Informal Environments For Educating Primary I Learners, Frances Neville

Masters Theses

The federal government has made education a competition among ourselves. Learning is not a rivalry to be imposed on our physical and cognitive development as humans. Escalating beliefs recognize education is more encompassing than CCSS, assessments and the grade level time frames in which standards are to be taught. On the precipice of anti-intellect, low expectations, and what has been termed “The Dumbing of America” an investigation into what it would take to close the achievement gap and increase student learning is overdue.

The goal for my Michigan based project, S.T.E.A.M. Daises, was to develop a program focusing on the …

Investigating Disparities And Safety Equity In Pedestrian Nighttime Crashes In Michigan, Sia Isaria Mwende

Masters Theses

For the past eleven years (2011 - 2021) in Michigan, 76 percent of all fatal pedestrian crashes occurred at night. Over the same period, about 36 percent of pedestrian nighttime crashes were fatal or incapacitating (KA), while only 25 percent of daytime pedestrian crashes were fatal or incapacitating (KA). Previous studies suggest that, overall, poor neighborhoods and racial minorities are associated with more pedestrian crashes. With more fatal and incapacitating pedestrian crashes occurring at night, it is imperative to examine how these crashes are distributed by economic status and racial makeup. Therefore, this study aims to investigate the racial and …

On Hydrophobic Deep Eutectic Solvents: Thermo-Physical Properties And Applications In Gas Solubility, Shan Khai Liew

Masters Theses

Carbon dioxide (CO2) has been widely recognized as one of the greenhouse gases (GHGs) in the atmosphere. GHGs cause global warming, which will bring a lot of problems and irreversible changes. To curb CO2 emissions, much effort has been done. There are many technologies available for CO2 capture, such as amine scrubbing, pressure or temperature swing adsorption, membrane separation, and many solvents and absorbents that have been proposed for CO2 capture (e.g., zeolite, silica materials, graphene, activated carbon, etc.) at every stage (pre-combustion, post-combustion, oxy-combustion). However, these materials have their own drawbacks. Hydrophobic deep eutectic solvents (HDES) is a green …

Examining The Use Of Video Modeling With Verbal Feedback To Enhance Performance In Springboard Divers, Erin M. J. Isola

Masters Theses

There is a growing body of literature examining the use of behavior analytic coaching techniques to enhance athlete performance across many different sports. To date, no studies have focused on performance improvement in springboard diving. Springboard diving skills are complex behavior chains and require the accurate performance of multiple smaller, component skills. Several studies have examined different types of feedback to teach and improve complex motor skills in sports other than springboard diving (BenitezSantiago & Miltenberger, 2016; Kelley and Miltenberger, 2016; Quinn et al., 2019; Walker et al., 2020). In one such study, Walker et al. (2020) combined video and …

Assessment Of Industrial Policies In Ghana: A Case Study On The Current Policy Of One District One Factory Policy (1d1f), Ama Nyamekye Obenewa Otoo

Masters Theses

Industrialization has been the weakest link in Ghana’s economic development efforts. Import-substitution industrialization policy of the 1960s-1980s and the outward liberalized industrialization policy of 1990-2020 (Vision 2020), have failed to achieve the goals of industrialization. This is due to several reasons including the selfish interests of these political leaders and lack of technological advancement. In 2017, the elected New Patriotic Party (NPP), announced a new industrialization policy known as “one district, one factory" (1D1F), which was a political campaign promise to realign industrial strategies. The goal of this policy is to ensure that industries are spread equitably among the country's …

Seeing Beyond: A Feminist Psychoanalytic Approach To The Politics Of The Cinematic Gaze, Sofia Koukia

Masters Theses

This essay presents a feminist psychoanalytic approach to the cinematic gaze which employs late Lacanian film theory in order to construct a conception of the gaze that allows for its political significance to emerge. The gaze is hereby understood as something that the subject (the spectator) encounters in the object (the film) and, also, as what constitutes the epitome of the cinematic experience. It is regarded as being inherently political, existing within the realm of the Lacanian real in the form of an objet petit a (or object-cause of desire), and exhibiting itself in the world(s) of fantasy and/or desire. …

Exploring The Effects Of Tree Roots On Infiltration Process, Nazife Onaral

Masters Theses

Effects of the root structures on soil infiltration dynamics are not clearly defined. Imaging the complex tree root structures and movement of water through the root ball is a challenging task to achieve without damaging the trees and roots by conventional methods. Commonly used methods are invasive, labor-intensive, and not easily accessible. Ground Penetrating Radar (GPR) has commonly been used to characterize soil profiles and it can be a reliable tool to map complex root structures with a novel high-resolution circular data collection technique. Electrical resistivity tomography (ERT) is another reliable geophysical method to image infiltration processes by the change …

Suicide At The Intersection Of Race And Gender, Marina Geider

Masters Theses

Sociological studies have examined suicide rate differences between groups since the work of Durkheim in 1897, and current literature still draws on his classic theories and methods. Although research has begun identifying the social factors that affect the suicides of Black and White populations differentially, little progress has been made towards an understanding of Black female suicide. The present study takes an intersectional approach to Durkheim's social integration-regulation thesis to bridge this gap. Several negative binomial regression analyses were employed to model suicide counts for Black men, Black women, non-Hispanic White men, and non-Hispanic White women in the United States. …

The Design And Development Of A Miniature Gridded Ecr Ion Thruster, Nicholas Nuzzo

Masters Theses

Plasma propulsion, a specific subset of electric propulsion (EP), is a class of space propulsion that produces plasma by excitation of a propellant at or above its ionization energy. This ionized propellant is then accelerated by an externally applied field (magnetic and/or electric) and produces thrust. There is an increasing need for miniaturization in spacecraft technology and the use of plasma EP devices in space propulsion. These systems provide an advantage over traditional chemical propulsion solutions which are less efficient and have more mass. Miniaturization of EP devices allows missions to have more space and mass available for their payloads …

The Impact Of A Realistic Job Preview Experience On Training Fluency, Learner Reactions, And Job Performance, Jessica Rocheleau

Masters Theses

Although the training and development literature has delineated which instructional approaches are most effective, training approaches are often selected based on entertainment value rather than empirical evidence of efficacy (Karthik et al., 2019). One reason for this trend may be learners’ positive reactions to entertaining instruction and negative reactions to effective instruction. Researchers may begin validating a means for addressing this problem by investigating methods for promoting job satisfaction within a training context. The proposed study compared the effects of two training orientation approaches on learner fluency, reactions, and job performance. A total of 175 participants were randomly assigned to …
