This paper explores women and bicycling, with the focus of looking at how to get more women onto the bicycle in Tempe, Arizona. The main areas of interest for this study are improvements to bicycling infrastructure and an increase in the safety and the perception of safety of women cyclists in the Tempe area. In order to explore this topic, an online survey of 75 Arizona State students was conducted. From the results women were primarily concerned with their safety due to the condition of the overall infrastructure and the lack of bicycle related improvements. Research such as this that examines women and cycling is significant due to the current underrepresentation of women in the cycling community and has the potential to improve safety and increase bicycle ridership.

Over the course of this paper, the overall role and effect street art has on a city and its development will be discussed. It will touch generally on the topic of street art history and how it stems from graffiti practices. While also mentioning two well known street artists that changed how the form can be perceived and applied to the streets, ultimately being a factor in growing city environments. The difference in definitions of street art and graffiti will also be discussed with reference to its overall subjectiveness, followed by street arts interconnectedness with the law. This will lead up to street art and whether it is a factor in gentrification and how this plays a part in the creative city. It will discuss later if keeping street art out is the response to stop gentrification, while also adding to the idea that street art is selling a false sense of city beautification and used as a ploy marketing tool. Several options of art-led gentrification will be analyzed, as well as its varying effects on the planning of a city. Eventually, this will all lead to an analysis of Roosevelt Row and how the presence of street art within the arts district will cause the district to grow and develop in the future, as it becomes a prime location in the contexts of the revitalizing downtown area.

Communicating climate risks is crucial when engaging the public to support climate action planning and addressing climate justice. How does evidence-based communication influence local residents’ risk perception and potential behavior change in support of climate planning? Built upon our previous study of Climate Justice maps illustrating high scores of both social and ecological vulnerability in Michigan’s Huron River watershed, USA, a quasi-experiment was conducted to examine the effects of Climate Justice mapping intervention on residents’ perceptions and preparedness for climate change associated hazards in Michigan. Two groups were compared: residents in Climate Justice areas with high social and ecological vulnerability scores in the watershed (n=76) and residents in comparison areas in Michigan (n=69). Measurements for risk perception include perceived exposure, sensitivity, and adaptability to hazards. Results indicate that risk information has a significant effect on perceived sensitivity and level of preparedness for future climate extremes among participants living in Climate Justice areas. Findings highlight the value of integrating scientific risk assessment information in risk communication to align calculated and perceived risks. This study suggests effective risk communication can influence local support of climate action plans and implementation of strategies that address climate justice and achieve social sustainability in local communities.

Nonlinear responses in the dynamics of climate system could be triggered by small change of forcing. Interactions between different components of Earth’s climate system are believed to cause abrupt and catastrophic transitions, of which anthropogenic forcing is a major and the most irreversible driver. Meantime, in the face of global climate change, extreme climatic events, such as extreme precipitations, heatwaves, droughts, etc., are projected to be more frequent, more intense, and longer in duration. These nonlinear responses in climate dynamics from tipping points to extreme events pose serious threats to human society on a large scale. Understanding the physical mechanisms behind them has potential to reduce related risks through different ways. The overarching objective of this dissertation is to quantify complex interactions, detect tipping points, and explore propagations of extreme events in the hydroclimate system from a new structure-based perspective, by integrating climate dynamics, causal inference, network theory, spectral analysis, and machine learning. More specifically, a network-based framework is developed to find responses of hydroclimate system to potential critical transitions in climate. Results show that system-based early warning signals towards tipping points can be located successfully, demonstrated by enhanced connections in the network topology. To further evaluate the long-term nonlinear interactions among the U.S. climate regions, causality inference is introduced and directed complex networks are constructed from climatology records over one century. Causality networks reveal that the Ohio valley region acts as a regional gateway and mediator to the moisture transport and thermal transfer in the U.S. Furthermore, it is found that cross-regional causality variability manifests intrinsic frequency ranging from interannual to interdecadal scales, and those frequencies are associated with the physics of climate oscillations. Besides the long-term climatology, this dissertation also aims to explore extreme events from the system-dynamic perspective, especially the contributions of human-induced activities to propagation of extreme heatwaves in the U.S. cities. Results suggest that there are long-range teleconnections among the U.S. cities and supernodes in heatwave spreading. Findings also confirm that anthropogenic activities contribute to extreme heatwaves by the fact that causality during heatwaves is positively associated with population in megacities.
