Description
Affect is a domain of psychology that includes attitudes, emotions, interests, and values. My own affect influenced the choice of topics for my dissertation. After examining asteroid interiors and the Moon’s thermal evolution, I discuss the role of affect in online science education. I begin with asteroids, which are collections of smaller objects held together by gravity and possibly cohesion. These “rubble-pile” objects may experience the Brazil Nut Effect (BNE). When a collection of particles of similar densities, but of different sizes, is shaken, smaller particles will move parallel to the local gravity vector while larger objects will do the opposite. Thus, when asteroids are shaken by impacts, they may experience the BNE as possibly evidenced by large boulders seen on their surfaces. I found while the BNE is plausible on asteroids, it is confined to only the outer layers. The Moon, which formed with a Lunar Magma Ocean (LMO), is the next topic of this work. The LMO is due to the Moon forming rapidly after a giant impact between the proto-Earth and another planetary body. The first 80% of the LMO solidified rapidly at which point a floatation crust formed and slowed solidification of the remaining LMO. Impact bombardment during this cooling process, while an important component, has not been studied in detail. Impacts considered here are from debris generated during the formation of the Moon. I developed a thermal model that incorporates impacts and find that impacts may have either expedited or delayed LMO solidification. Finally, I return to affect to consider the differences in attitudes towards science between students enrolled in fully-online degree programs and those enrolled in traditional, in-person degree programs. I analyzed pre- and post-course survey data from the online astrobiology course Habitable Worlds. Unlike their traditional program counterparts, students enrolled in online programs started the course with better attitudes towards science and also further changed towards more positive attitudes during the course. Along with important conclusions in three research fields, this work aims to demonstrate the importance of affect in both scientific research and science education.

Description
The inspiration to undertake this pilot study came after observation and reflection by the clinician-researcher, a board-certified music therapist who has used the harp as the primary instrument when facilitating sessions, on hundreds of music therapy sessions that took place at a facility for behavioral health and chemical dependency. It was observed that the use of improvised harp music as a therapeutic intervention within the context of a music therapy session seemed to relax patients who reported that they were nervous or anxious, and it was also noted that following a listening exercise that consisted of improvised harp music, patients appeared calmer and reported that they felt more comfortable. This research aims to determine if improvised harp music at the opening of a music therapy session creates a calmer environment in which to share information, compared with a guided verbal relaxation and ambient ocean drum sounds for the opening of the music therapy session. Social-behavioral research was conducted in the form of a fifty minute individual music therapy session with six subjects. Each therapy session used improvised music and verbal processing with the therapist, with three subjects in the experimental group and three in the control group. Each individual rated two different types of affective responses on scales of one to ten and completed a five-question survey at the end of the session. All the research subjects showed an increase in positive affect at the end of the music therapy session.
