Description
Geoscience educators commonly teach geology by projecting a photograph in front of the class. Geologic photographs often contain animals, people, and inanimate objects that help convey the scale of features in the photograph. Although scale items seem innocuous to instructors and other experts, the presence of such items is distracting and has a profound effect on student learning behavior. To evaluate how students visually interact with distracting scale items in photographs and to determine if cueing or signaling is an effective means to direct students to pertinent information, students were eye tracked while looking at geologically-rich photographs. Eye-tracking data revealed that learners primarily looked at the center of an image, focused on faces of both humans and animals if they were present, and repeatedly returned to looking at the scale item (distractor) for the duration an image was displayed. The presence of a distractor caused learners to look at less of an image than when a distractor was not present. Learners who received signaling tended to look at the distractor less, look at the geology more, and surveyed more of the photograph than learners who did not receive signaling. The San Antonio area in the southern part of the Baja California Peninsula is host to hydrothermal gold deposits. A field study, including drill-core analysis and detailed geologic mapping, was conducted to determine the types of mineralization present, the types of structures present, and the relationship between the two. This investigation revealed that two phases of mineralization have occurred in the area; the first is hydrothermal deposition of gold associated with sulfide deposits and the second is oxidation of sulfides to hematite, goethite, and jarosite. Mineralization varies as a function of depth, whereas sulfides occurring at depth, while minerals indicative of oxidation are limited to shallow depths. A structural analysis revealed that the oldest structures in the study area include low-grade to medium-grade metamorphic foliation and ductile mylonitic shear zones overprinted by brittle-ductile mylonitic fabrics, which were later overprinted by brittle deformation. Both primary and secondary mineralization in the area is restricted to the later brittle features. Alteration-bearing structures have an average NNW strike consistent with northeast-southwest-directed extension, whereas unaltered structures have an average NNE strike consistent with more recent northwest-southeast-directed extension.

Description
This research investigates the conditions under which people use consumption choices to signal accurate versus enhanced information about themselves to others. Across five studies, I demonstrate that activating a self-verification, as opposed to self-enhancement, motive leads consumers to choose products that signal accurate information about a self-view, even when this view is negative. I replicate this finding across several self-view domains, including physical attractiveness, power, and global self-esteem. However, I find that this effect is attenuated when consumers have a high fear of negative social evaluation. My findings suggest that this type of consumption, in which choice is driven by the desire to be seen accurately (vs. positively), can explain abundant real-world behavior; contradicting the notion that consumers choose products primarily for self-enhancement.

Description
The traditional action-response perspective has largely ignored the role of language in competitive dynamics. In this study, I treat language (i.e., word response) as an alternative way to react to rivals when a firm is attacked, in addition to no reaction and action-based reaction. Word response is a specific and public announcement of a focal firm’s potential move in reaction to a competitor’s word or action attack. To explore the underlying mechanism behind word responses, I aim to answer two major questions. The first question is under what situations are responders motivated to use words as competitive responses? For this question I emphasize characteristics of the action, the market, and the actor, using measures such as action type, market dependence of the responder, multimarket contact of the responder in the market, and the competitive aggressiveness of the actor. The second question is what kinds of responders are more likely to use words as competitive responses? For this question, I focus on responder characteristics, such as firm reputation, CEO tenure, and CEO duality. According to Porter’s competitive signaling theory, I argue that responders can use words in reaction to an attack in order to test the waters, deter rivalry, and demonstrate toughness because word responses require few resources, can be accomplished quickly, are reversible, while at the same time still carrying some commitment. Besides incorporating language into the action-response perspective, my dissertation also further integrates the upper-echelons perspective with competitive dynamics research, providing a more realistic and complete understanding of competitive engagement. I test my theory in the consumer electronics (CE) industry with 20 major global CE manufacturers between 2007 and 2014.

Description
Web-based learning resources have been criticized as being developed with minimal consideration as to the effectiveness of the design principles or guidelines used to create them. Extraneous material is oftentimes present and necessary for learners to engage in effective learning with multimedia learning material. Signaling learners towards important information between images and corresponding text has been shown to be an effective method for providing learners a way to quickly find information between the two parts of the learning material. However, not all signaling methods are equally effective in all applications. This study investigates a novel signaling method, using spatial isolation of text, as a way to signal learners in a web-based format compared to a traditional highlighting method and a non-signaled control group. Improved learning performance was observed for knowledge retention using text isolation as the signaling method, but no other significant effects were observed between the other conditions. Additionally, transfer of knowledge across all conditions showed no significant differences either. While minimal support for the effectiveness of isolated text signaling was demonstrated, the statistical means trend across all post-test knowledge assessments suggest that further evaluation of the novel signaling method is justified.
