An Eeg Study On Loneliness And Recognition Memory, Carmen Jia Wen Chek

Electronic Theses and Dissertations

Loneliness, the perception of unmet social needs, has been shown to relate to recollection-based recognition deficits, but the relationship between loneliness and recognition memory (i.e., recollection and familiarity) has not been thoroughly examined. The current study hypothesized that more lonely individuals would have lower recognition memory performance, specifically recollection, with smaller ERP parietal old-new effects than less lonely individuals. Forty participants, grouped into less (n = 13) and more (n = 9) lonely groups based on their R-UCLA responses, completed an associative memory task. EEG was used to assess recognition memory effects. Results showed no significant difference in …

Studies Of Quaternary Depositional Systems Of The Coastal Plain And Inner Continental Shelf Along The Georgia Bight: South Carolina And Georgia, U.S.A., Joshua H. Long

Electronic Theses and Dissertations

The Quaternary stratigraphy of the continental shelf offshore of South Carolina consists of stratigraphic units deposited in coastal plain, shallow marine, and shelfal environments bound by composite erosional surfaces that developed in response to numerous glacioeustatic cycles and overprinted by regional uplift. These units are commonly distributed laterally rather than stacked vertically, a function of the long-term, low shelf gradient and the resulting lack of accommodation. This study integrates high-resolution geological and geophysical data sets acquired offshore and onshore with existing data onshore into a comprehensive conceptual model describing the Quaternary geologic evolution of the coastal plain and continental shelf …

Creativity And The Evolution Of Musical Ideas: Putting The Creative Principles Of Austin Kleon To Work, Dustin Schulze

Electronic Theses and Dissertations

All composers internalize the musical ideas of other composers and infuse them into their own original work. But the fear of being labeled “derivative” causes most composers to shy away from talking about these influences openly and directly. In Austin Kleon’s book, Steal Like an Artist, he faces the issues of influence and imitation in a deliberately self-aware fashion. The principal objective of this thesis will be to internalize the musical ideas of other composers and infuse them into an original musical work of my own, entitled Kyros. By articulating the exact way in which I am using the work …

Salt In The Deep Marine, Rachel Bollinger

Electronic Theses and Dissertations

ABSTRACT

Rachel Allison Bollinger: Salt in the Deep Marine

(Under the direction of Dr. Christine Butterworth-McDermott and Dr. John McDermott)

The surface tension present between liquid and air is due to the fact that liquid molecules are highly attractive to one another. Because of this, the surface of water acts like an elastic membrane, allowing human hands or light insects to sit or slide on its surface. For a moment or two, the hand or the insect seems to occupy both the water and the air simultaneously. This commonplace phenomenon is explored in the poetry collection, Salt in the Deep …
