Thinking About Making A Connection: Exploring The Role Of Metacognition In Recognition Memory For Associative Information, Mario E. Doyle

Theses and Dissertations (Comprehensive)

In a set of six experiments, the relation between metacognition and associative memory was explored. The purpose was to determine whether the metacognitive behaviors that are used with item memory are also used with associative memory. Different memory systems have separate underlying processes which can cause mnemonic strategies to only be useful for some types of memory. People use metacognition to monitor and control their memory; however, it is uncertain whether metacognitive monitoring and control are the same for different types of memory. The research presented in this dissertation demonstrates the similarities and differences between metacognitive behavior for item and …

Exploring The Relationship Between Drought And Population Change On The North American Great Plains, 1970-2010, George Heath

Paper Gangsters: White Collar And Corporate Crime On Film, Jacob Kavoukis

Theses and Dissertations (Comprehensive)

Many of us have never been victims of a serious crime and as a result, rely on the media in its various forms to provide us with information that we can rely on as being accurate in order to learn about it. Information on white-collar crime in the media differs from more common street crime in that it receives very little attention. The lack of attention could be because these crimes are considered non-violent and victimless, are committed by those of high social stature and power and are often complex and challenging to understand. Films can play an important role …

Enemies, Allies, And Opportunities: The Politics Of Noblewomen’S Lawsuits In Early Modern Piedmont, Catherine Ferrari

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation considers early modern law courts as political venues in which noble families not only asserted claims to wealth, property, and inheritance but also sought to enhance their reputation and influence. By studying the archives of elite families in Piedmont from the mid-sixteenth to the mid-seventeenth centuries, I argue that noblewomen used the law to gain a political voice, defending their legal claims against other family members in highly visible conflicts in which not only their property but their standing at the court of the duke of Savoy was at stake. These women exploited legal procedures and drew on …

Modeling Of Inverter-Based Microgrid For Small-Signal And Large-Signal Stability Analysis, Vishal Verma

Graduate Theses, Dissertations, and Problem Reports (ETD)

Integration of inverter-based resources (IBRs) such as solar photovoltaic, wind, and battery storage, is both a boon and a bane for electric power systems. On one hand, IBRs have helped in making electrical energy a clean (carbon-free) source of energy. On other hand, the dynamics of IBRs have changed the way power system studies have been carried out. With the advantages IBRs offer over conventional resources, it is assumed that a small distribution power system (microgrid) will have a 100% IBRs penetration in the future. Such a microgrid can operate in grid-connected mode or in an islanded mode. Both modes …

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation sought to interrogate the ways in which White, rural students from West Virginia conceptualized diversity before, during, and since their transition to a large PWI in their home state. Using Critical Whiteness Studies and intersectionality as driving theory, student participants and I engaged in deconstruction of privilege through individual and culture circle conversations. Then, participants engaged in self-reflection using codes established in Critical Whiteness (White normativity, White complicity, epistemologies of ignorance) as well as participant-drive codes that reflected other forms of identity-based power. Three waves of reflection demonstrate the participants’ continued cycle of praxis (reflection, action, repeat) and …

The Largest Linear Subspace Contained In Darboux-Likr Functions On R, Gbrel Mohammad Albkwre

Graduate Theses, Dissertations, and Problem Reports (ETD)

Consider an arbitrary $\mathcal F\subset\mathbb R^\mathbb R$, where the family $\mathbb R^\mathbb R$ of all functions from $\mathbb R$ to $\mathbb R$ is considered as a linear space over $\mathbb R$. Does $\mathcal F\cup\{0\}$ contain a non-trivial lineal subspace? If so, how big the vector space can be? These questions are at the core of lineability theory. In particular, we say that a family $\mathcal F\subset\mathbb R^\mathbb R$ is {\em lineable (in $\mathbb R^\mathbb R$)}\/ provided there exists an infinite dimensional linear space contained in $\mathcal F\cup\{0\}$.

There has been a lot of attention devoted to lineability problem of subsets …

Passive wireless devices are generally classified as near-field and far-field devices based on the interrogation distance. Near-field sensors are placed at …

Pathfinding Fast Radio Bursts Localizations Using Very Long Baseline Interferometry, Pranav Rohit Sanghavi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fast radio bursts (FRBs) are millisecond-duration, bright radio transients of extragalactic origin. The Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope’s CHIME/FRB instrument and other radio telescopes across the globe have detected hundreds of FRBs. Their origins are a mystery. Precise localization within the host is critical to distinguish between progenitor models. This can be achieved through Very Long Baseline Interferometry (VLBI). Until now, VLBI localizations have only been carried out in targeted follow-up observations of some repeating sources which comprise a small fraction of the FRBs.

For this work, an interferometric array of 6m dishes was constructed at the Green …
