A Multi-Method Examination Of The Effects Of Students’ Unconscious Biases On Student Evaluations Of Instructors, Brittany M. Kowalski

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this dissertation, I complete three studies to evaluate potential reactions to target role congruity, especially gender role congruity, through an examination of Student Evaluations of Instructors (SEIs). Target role congruity refers to assessments an observer makes of whether or not the various roles a target person fills “fit” with one another. For example, a woman surgeon may be perceived as being in an incongruent role due to the masculine characteristics associated with the occupation and the continued dominance of men in the field. Researchers utilizing congruity theories has shown that both women and men in roles that are incongruent …

Localization Algorithms For Gnss-Denied And Challenging Environments, Chizhao Yang

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this dissertation, the problem about localization in GNSS-denied and challenging environments is addressed. Specifically, the challenging environments discussed in this dissertation include two different types, environments including only low-resolution features and environments containing moving objects. To achieve accurate pose estimates, the errors are always bounded through matching observations from sensors with surrounding environments. These challenging environments, unfortunately, would bring troubles into matching related methods, such as "fingerprint" matching, and ICP. For instance, in environments with low-resolution features, the on-board sensor measurements could match to multiple positions on a map, which creates ambiguity; in environments with moving objects included, the …
