1. Exploring Undergraduate Civil Engineering Students’ Perceptions of Infrastructure Inequities: A Pilot Study

   Bolding, C.J.; Ogle, J.; and Rapa, L. (July 2021, 2021 ASEE Annual Meeting)

   As social justice issues facing our nation continue to be placed in the foreground of everyday life, it is important to understand how undergraduate civil engineering students perceive and understand relations between social justice and our infrastructure systems. Additionally, as more civil engineering undergraduate programs increase the emphasis on ethics and equity issues in their curricula, we must also seek to understand students’ awareness of their influence, as civil engineering professionals, to improve infrastructure systems that contribute to injustice and inequity. This paper presents findings from a pilot study conducted as part of an NSF-funded grant implementing cultural and curricular changes in a medium-sized civil engineering department in the southeast. Drawing on frameworks that examine how individuals critically understand systems of oppression, and the justification used to explain these systems this work examined student perceptions of inequities in societal infrastructure systems. The present study was guided by the following research questions: (1) Are undergraduate civil engineering students critically aware of inequities in society’s infrastructure systems? (2) To what degree are undergraduate civil engineering students comfortable challenging the status quo? (3) Is there an association between students’ critical awareness of inequitable infrastructure systems and their agency to promote systemic change as civil engineering professionals? Study data included survey responses to validated scales measuring: critical consciousness, system justification beliefs, social empathy, and sociopolitical control beliefs. New instrumentation was also piloted assessing equity-related perceptions and beliefs about civil engineering and infrastructure systems. Participants were junior and senior undergraduate civil engineering students (n = 21) enrolled in a professional development, community, and strategic change course, with data collected throughout the Fall 2020 semester. Results suggest that students did have awareness of infrastructure inequities and, on average, did not have strong system justification beliefs. However, there was not an association between students’ awareness of inequities and their agency beliefs about promoting systemic change as civil engineers. After presenting study results, we discuss implications of study results and propose directions for future research.

2. Residents manage dynamic plant communities: Change over time in urban vegetation

   https://doi.org/10.3389/fevo.2022.944803  

   Wheeler, Megan M.; Larson, Kelli L.; Cook, Elizabeth M.; Hall, Sharon J. (December 2022, Frontiers in Ecology and Evolution)

   Introduction Integrated social and ecological processes shape urban plant communities, but the temporal dynamics and potential for change in these managed communities have rarely been explored. In residential yards, which cover about 40% of urban land area, individuals make decisions that control vegetation outcomes. These decisions may lead to relatively static plant composition and structure, as residents seek to expend little effort to maintain stable landscapes. Alternatively, residents may actively modify plant communities to meet their preferences or address perceived problems, or they may passively allow them to change. In this research, we ask, how and to what extent does residential yard vegetation change over time? Methods We conducted co-located ecological surveys of yards (in 2008, 2018, and 2019) and social surveys of residents (in 2018) in four diverse neighborhoods of Phoenix, Arizona. Results 94% of residents had made some changes to their front or back yards since moving in. On average, about 60% of woody vegetation per yard changed between 2008 and 2018, though the number of species present did not differ significantly. In comparison, about 30% of woody vegetation changed in native Sonoran Desert reference areas over 10 years. In yards, about 15% of woody vegetation changed on average in a single year, with up to 90% change in some yards. Greater turnover was observed for homes that were sold, indicating a “pulse” of management. Additionally, we observed greater vegetation turnover in the two older, lawn-dominated neighborhoods surveyed despite differences in neighborhood socioeconomic factors. Discussion These results indicate that residential plant communities are dynamic over time. Neighborhood age and other characteristics may be important drivers of change, while socioeconomic status neither promotes nor inhibits change at the neighborhood scale. Our findings highlight an opportunity for management interventions, wherein residents may be open to making conservation-friendly changes if they are already altering the composition of their yards.

3. Living in the ‘Blue Zone’ of a sea-level rise inundation map: Community perceptions of coastal flooding in King Salmon, California

   https://doi.org/10.1016/j.crm.2024.100596  

   Richmond, Laurie; Kunkel, Kristina (January 2024, Climate Risk Management)

   As sea-level rise (SLR) inundation maps proliferate, it is important to study their politics – both how they are created and how they act upon and shape various lives and places. This paper uses the example of King Salmon, CA – a rural, low-income residential area projected to be one of the most at risk to SLR on the US West Coast – to examine how a community responds to external projections showing SLR risk to their homes and businesses. Through interviews with 17 King Salmon community members and observation of a county-hosted ‘communities at risk’ workshop, we examined the community’s social context, their past experiences with flooding, and their reaction to SLR projection maps including what next steps they would like to see taken. Residents expressed a strong connection to the place, noting that it is one of the few affordable places to live on the coast in California. We found that residents already live with regular flooding during larger tides of the year and have taken steps to adapt. We observed a strong generational component in responses to projection maps with many older respondents believing or hoping that the worst effects from SLR would not come until after they passed away. Residents expressed a lack of faith in government to address flooding concerns both at present and into the future, noting that general maintenance issues have gone unaddressed for decades. Many residents interviewed and observed seemed open or at least resigned to the possibility of relocation at a future undetermined time. This work reveals the power dynamics inherent in climate projections like SLR maps, which, due to their technical nature and mobility, can leave communities out of conversations related to potential futures. Findings also have implications related to climate and SLR work – highlighting the importance of understanding community context; contributing to equity considerations about how wealth and other demographic factors shape how communities interact with SLR planning; and spotlighting the need for sustained learning, engagement, and co-production with communities in the ‘blue zones’ of SLR inundation maps.

4. "Crime and Neighborhood Change in the Nation’s Capital: From Disinvestment to Gentrification."

   https://doi.org/10.1177/00111287211005394

   null (Ed.)

   Research on crime and neighborhood racial composition establishes that Black neighborhoods with high levels of violent crime will experience an increase in Black residents and concentrated disadvantage—due to the constrained housing choices Black people face. Some studies on the relationship between gentrification and crime, however, show that high-crime neighborhoods can experience reinvestment as well as displacement of Black residents. In Washington, DC, we have seen both trends—concentration of poverty and segregation as well as racial turnover and reinvestment. We employ a spatial analysis using a merged data set including crime data, Census data, and American Community Survey (ACS) data to analyze the relationship between crime and neighborhood change at the Census tract level. Our findings demonstrate the importance of distinguishing between periods of neighborhood decline and ascent, between the effects of property and violent crime, and between racial change and socioeconomic change.

5. Status, social norms, or safety? understanding intended and reported bottled water use in Urban Mashhad, Iran

   https://doi.org/10.2166/wh.2022.319  

   Mir Mohamad Tabar, Seyed Ahmad; Brewis, Alexandra; Sohrabi, Maryam (December 2022, Journal of Water and Health)

   Abstract Personal plastic-bottled water use is highly commodified, raising an array of cost and environmental concerns, and continues to grow globally. Studies in lower-income nations suggest safety as a primary motivation for such water purchases, but studies in high-income nations with greater relative affordability suggest it is more tied to socially situated consumer decisions like status and aesthetics. Here, we consider what motivates bottled water use in an urban city (Mashhad) in a middle-income predominantly Muslim country (Iran), where there is a likely intersection of safety (due to contamination), social norms, and status concerns. Surveys were collected with a random population-representative sample of resident adults from discrete households (n = 970). Structured equation modeling testing the relative effects on reported bottled water intentions and use shows that all these factors are shaping people's decisions. Both higher- and lower-income residents’ responses suggest that status and social norms considerably influence intentions to use. Overall, even despite real safety issues with tap water, social norms and status concerns seem to weigh more heavily on residents’ decisions to drink bottled water.
