Item Modeling the Influence of Family, Social Context, and Spatial Proximity on Use of Nonmotorized Transport Mode(National Academy of Sciences, 2011) Ferdous, Nazneen; Pendyala, Ram M.; Bhat, Chandra R.; Konduri Karthik C.This paper presents a joint model of walking and bicycling activity duration using a hazard based specification that recognizes the interval nature of time reported in activity-travel surveys. The model structure takes the form of a multilevel hazard-based model system that accounts for the range of interactions and spatial effects that might affect walking and bicycling mode use. In addition to the individual-specific factors, family (household-specific) interactions, social group (peer) influences, and spatial clustering effects are also considered as potential factors that contribute to heterogeneity in non-motorized transport mode use behavior. The model system presented is capable of accommodating grouped duration responses often encountered in activity-travel surveys. A composite marginal likelihood estimation approach is adopted to estimate parameters in a computationally tractable manner. The model system is applied to a survey sample drawn from the recent 2009 National Household Travel Survey in the United States. Model results show that there are significant unobserved family-level, social group, and spatial proximity effects that contribute to heterogeneity in walking and bicycling activity duration. The unobserved effects were also found to have a differential impact on bicycling activity duration, thus suggesting the need to treat and model walking and bicycling separately in transportation modeling systems.Item Revisiting “Black Downtown”: Spatial and Storytelling Practices in Austin, Texas(2020-05) Mata, Ryan Andrew; Campbell, CraigHarrison David Eppright, a multi-generational black artist, creates and participates in an everyday performance of culture and visibility through his capacity as a tour guide for the city and an ambassador for Austin’s visitor services. Harrison has a unique subjective experience affected by intersecting identities and oppressions, including those along the lines of race and sexuality. I examine how he assigns meaning to places that are fading, getting bulldozed, or enduring. This thesis explores how Harrison utilizes storytelling and walking tours in the shifting landscape of East Austin in order to find pride in “home” while making visible the cultural makeup being threatened by current circumstances such as gentrification and displacement. These neighborhoods in Austin, which were once designed as a “negro district”, now face the problem of losing their identity to a host of new development that has led to the pricing-out and displacement of mostly black and brown working-class residents and businesses.
