The assumed ordinal relationship between seriously considering, planning, and attempting suicide in the 1999 Youth Risk Behavior Survey was examined by constructing a trajectory that identified all possible response patterns among the four questions measuring suicidal activity. Statistical analysis tested for differences in frequency of risk behaviors across levels of the trajectory. Overall, the trajectory provided insight to the progression of adolescent suicidal activity and demonstrated usefulness as a measure of suicidal intent. Significant differences between means of dependent variables at each level of the normative trajectory supported the hypothesis that frequency of risk behaviors increases monotonically with successive suicidal thought and behavior.

Perceptions of sea-level rise in urban, environmental justice (EJ) communities are poorly understood. These communities' long-term vulnerability may increase as a result of the interaction of sea-level rise and legacy pollution. This article presents research on experience and perceptions of sea-level rise, flooding, legacy pollution/contamination, and health in an EJ community in northern Delaware. The community is in close proximity to documented brownfields and other hazardous sites, and is located where there are long-term projections of water inundation due to sea-level rise. Researchers administered quantitative surveys at local events that measured knowledge and concern for these issues; conducted focus groups that enabled a deeper understanding of survey results; and examined community perceptions relative to existing policy tools, including sea-level rise inundation maps and documentation of contaminated sites. The mixed-method approach created a baseline of perceptions on pollution, flooding, a health-environment connection, and sealevel rise. Key findings include the value of experiential knowledge of local flooding to improve efficacy of future policy prescriptions, and how a lack of knowledge of sea-level rise, coupled with great concern for it, might be explained by longtime familiarity with flooding issues in the community.

We highlight the potential for paradoxical impacts of green infrastructure integrated with urban redevelopment. Absent directly addressing social inequalities in parallel efforts, green infrastructure may lead to negative health outcomes of disadvantaged residents, including eventual displacement. We present the research literature and reviews on this topic. We next highlight the case of recent in-migration of higher-income Whites and others in South Wilmington, Delaware, spurred on by high-end Riverfront redevelopment at Christina Landing. This migration may obscure how greening efforts-such as a new wetlands park to control area flooding-influence health outcomes in Southbridge, a low-income, African American neighborhood also within South Wilmington. The area's Census tract boundary, often used in both health and equity assessments, is shared by these distinctive communities. When viewed through the lens of inequality, greening can have multi-faceted impacts that structure health outcomes. We underscore the importance of the mitigation of its potentially harmful effects.
