Linguistic Correlates Of The Quiet Ego In Narratives About The Self, Katherine Maurer

Masters Theses

Increasingly, research has shown that the drive to elevate the self and the excessive pursuit of self-esteem have negative effects on well-being and mental health. In addition, many of the defensive and aggressive tendencies seen in psychological research can be seen as efforts to defend and elevate the self. In contrast to these tendencies, the quiet ego construct describes a state of ego balance characterized by an inclusive sense of identity, perspective-taking, detached awareness (mindfulness), and growth orientation. The quiet ego and related qualities have been associated with many positive outcomes. A body of research using the Linguistic Inquiry and …

Kids, Spouses, School, Oh My! The Non-Traditional Student Experience, Amber J. Webb

Masters Theses

According to the Hussar and Bailey (2017) the number of non-traditional students on college campuses are expected to rise, closing the size of gap in enrollment numbers between traditional and non-traditional students. Though, the non-traditional student has traditionally been defined as students aged 25 and older, this study used Horn and Carroll's (1996) definition, as students who possess certain characteristics that make them vulnerable to academic problems (i.e. delayed enrollment, part-time enrollment, financial independence, full-time employment while enrolled, having dependents, being a single parent, or not receiving a standard high school diploma). Horn and Carroll (1996) further used these characteristics …

Mixed-Criticality Real-Time Task Scheduling With Graceful Degradation, Samsil Arefin

Masters Theses

”The mixed-criticality real-time systems implement functionalities of different degrees of importance (or criticalities) upon a shared platform. In traditional mixed-criticality systems, under a hi mode switch, no guaranteed service is provided to lo-criticality tasks. After a mode switch, only hi-criticality tasks are considered for execution while no guarantee is made to the lo-criticality tasks. However, with careful optimistic design, a certain degree of service guarantee can be provided to lo-criticality tasks upon a mode switch. This concept is broadly known as graceful degradation. Guaranteed graceful degradation provides a better quality of service as well as it utilizes the system resource …

Numerical Simulation Study Of Factors Affecting Production Well Gel Treatment Using Linear Models With Crossflow, Kewei Shi

Masters Theses

"Conformance control is an inevitable topic related to water-flooding. Polymer gel has been proved to enhance oil recovery by blocking the existing water-breakthrough channels. Water that is injected subsequently will be directed to the unswept portion of the reservoir, replacing part of the remaining oil and increasing the oil-recovery factor. Prior to pilot tests of polymer gel treatment, laboratory experiments and numerical simulations are used to design the tests. Understanding physical meanings of key parameters that affect polymer gel treatment and relating the parameters from lab data and the simulator benefit field operation design.

Universal Wavefront Transmission Through Disordered Media, Jayson Robert Summers

Masters Theses

”When electromagnetic waves propagate through random dielectric media, they scatter in a predictable, deterministic way. The process is also fully reversible. If one sends an exiting wave backward through the same material, it will converge back to its original form and location in the same amount of time it took to originally propagate through the material. Due to this predictability, a great deal of research has went into studying these scattering processes in multimode fibers, diffusers, biological tissues, and other media. Scientists have turned random scattering material into focusing lenses, image transmitters, and highly transmitting media by controlling the impinging …

An Investigation Of The Influence Of The 2007-2009 Recession On The Day Of The Week Effect For The S&P 500 And Its Sectors, Marcel Alwin Trick

Masters Theses

"Several studies have shown that the mean returns and the volatility structure of stock markets change seasonally or by day of the week. For instance, some authors found out that Monday returns are lower compared to Friday returns or that volatility on Wednesdays are lower compared to the rest of the week. Other researchers showed that these effects have changed after certain periods of economic stress. This led to the question, whether the day of the week effects in returns and volatility are in the US stock market and if patterns have changed from pre-recession through the 2007-2009 recession into …
