The Teaching Interaction Procedure As Microintervention Training For Lgbtq+ Adults, Arianna Ty Lipton

Theses and Dissertations

Microaggressions are verbal behavior and environmental arrangements that communicate bias towards individuals of marginalized social groups (Sue, 2010). The LGBTQ+ community experiences high rates of interpersonal microaggressions, which have been associated with financial loss, community rejection, and mental health problems (Nadal et al., 2016). Sue et al., (2019) proposed the term “microintervention” to refer to behavioral strategies that function to reduce the harmful effects or the future frequency of microaggressions (Sue et al., 2019). Traditional inclusivity trainings have generally been developed outside of behavior analysis and focus on solely teaching skills to bystanders rather than training targets of discrimination actionable …

Low Reynolds Number Locomotion Near Interfaces In Two-Fluid Media, Avriel Rowena Mae Cartwright

Theses and Dissertations

Microorganisms often swim within complex fluid environments composed of multiple materials with very different properties. Biological locomotion, including swimming speed, is significantly impacted by the physical composition and rheology of the surrounding fluid environment, as well as the presence of phase boundaries and free interfaces, across which physical properties of the fluid media may vary greatly. Through computational simulations, we first investigate the classical Taylor’s swimming sheet problem near interfaces within multi-fluid environments using a two-fluid immersed boundary method. The accuracy of the methodology is illustrated through comparisons with analytical solutions. Our simulation results indicate that the interface dynamics and …
