The Impact Of A Neurofeedback Training Intervention On College Students' Levels Of Anxiety, Stress, Depression, And Cortisol, Caitlyn Bennett

Electronic Theses and Dissertations

Anxiety, depression, and stress are three of the most common experiences that impact college student functioning and academic achievement. At least one in six college students struggle with anxiety, increasing risk for developing depressive symptoms or disorders that further impact wellness. However, as mental health concerns increase across campuses, universities are not equipped to meet the demand of mental health support for college students. Neurofeedback (NF) training presents as an innovative intervention to treat anxiety, depression, and stress as it is designed to regulate brain processes in an effort to increase more effective brain functioning. A quasi-experimental, nonequivalent control group …

Featured Bookshelf: 2017 Women's History Month, Megan M. Haught

Featured Bookshelf

Women’s History Month began as a week-long celebration by in Sonoma, California in 1978 which was centered around International Women’s Day on March 8. A year later during a women’s history conference at Sarah Lawrence College, participants learned how successful the week was and decided to initiate similar in their own areas. President Carter issued the first proclamation for a national Women’s History Week in 1980. In 1987, Congress (after being petitioned by the National Women’s History Project) passed Pub. L. 100-9 designating March as Women’s History Month. U.S. Presidents have issued proclamations on Women’s History Month since 1988.

Grace Hopper And The Marvelous Machine: Lessons For Modern Technical Communicators From The Mark I Ascc Manual, Jessica Meyr

Electronic Theses and Dissertations

Women's technical writing achievements often go unrecognized, both due to the invisibility of technical writing professionals in general, and a lack of famous technical communication role models in particular. The purpose of this thesis is to analyze and present an early major work in the technical writing of Rear Admiral "Amazing" Grace Hopper, inventor of the compiler and an important figure in computer science history. Although Hopper is arguably best known for popularizing the idea of the "computer bug," her achievements in computer science extend from invention of the software compiler to tireless promotion of the programming language COBOL. Her …

Mechanochemical Synthesis Of Fuels From Sustainable Sources Utilizing Solid Catalysts, Jacob Todd

Electronic Theses and Dissertations

Mechanochemistry requires less solvents which results in less waste generation. The question becomes can we apply mechanochemistry to current chemical reactions and reduce the generation of waste. This process can be simple or can be very extensive resulting in the generation of large amounts of waste and very little product. A significant advantage of mechanochemistry is the reduced need for solvents that would be common place for reactions. Mechanochemistry transfers energy to reagents via impacts from milling media. Energy can be transferred to the reagents no matter their state-of-matter. Much of the current studies in mechanochemistry today are done using …

Six Degree Of Freedom Dynamic Modeling Of A High Altitude Airship And Its Trajectory Optimization Using Direct Collocation Method, Pradens Pierre-Louis

Electronic Theses and Dissertations

The long duration airborne feature of airships makes them an attractive solution for many military and civil applications such as long-endurance surveillance, reconnaissance, environment monitoring, communication utilities, and energy harvesting. To achieve a minimum energy periodic motion in the air, an optimal trajectory problem is solved using basic direct collocation methods. In the direct approach, the optimal control problem is converted into a nonlinear programming (NLP). Pseudo-inverse and several discretization methods such as Trapezoidal and Hermite-Simpson are used to obtain a numerical approximated solution by discretizing the states and controls into a set of equal nodes. These nodes are approximated …
