Native populations and the opioid crisis: forging a path to recovery.

American Indian/Alaska Native (AI/AN) populations have proven particularly susceptible to the opioid crisis in the USA, but the White House's 2019 national opioid policy roadmap is not structured to address AI/AN vulnerabilities. The concept of resilience, usually considered a positive system attribute, can be applied to complex systems to understand the larger compensatory interactions that restore systems to previous structures despite disruptions or interventions. The opioid crisis is a case of detrimental resilience because even effective interventions have not succeeded in eradicating opioid abuses. Resilience-based systemic interventions are needed to disrupt various aspects of systems while enhancing the social and cognitive abilities of affected populations to withstand the threat. This paper examines community characteristics, healthcare, and law enforcement within the context of AI/AN populations to emphasize the mechanisms that promote undesirable resilience for the opioid crisis. A research agenda bringing together systems science and management is needed to coordinate sectoral interventions and establish strategies to disrupt the resilient cycle of opioid addiction.

Environmental and Economic Trade-Offs of City Vehicle Fleet Electrification and Photovoltaic Installation in the U.S. PJM Interconnection.

Several cities are considering both photovoltaic (PV) generation and electric vehicles (EVs). A city evaluating a transition to an EV fleet has different decision criteria than private actors. This paper conducts a life cycle assessment and cost-benefit analysis for city vehicle fleet electrification decisions, using Pittsburgh, PA as a case study. The analysis includes several electric-grid scenarios and assesses the installation of distributed PV at city-owned parking facilities. Costs were included while comparing vehicle options, as were the emissions and externality costs of GHGs, SO2, and NOx from direct and upstream effects. For the vehicles under consideration for Pittsburgh's fleet, BEVs were always found to have lower GHG emissions than Hybrids. Lowering external costs with fleet electrification, however, was found to be dependent on a rapid transition to a cleaner grid. A peak capacity of about 6000 kW of PV is possible on Pittsburgh city-owned parking facilities. This capacity would produce greater than 30 times the yearly energy needs of the city's municipal vehicle fleet. However, the PV canopy structures over parking spaces potentially make systems costs prohibitive. This study provides a method for cities, counties, and other stakeholders to evaluate the potential benefits and costs of EVs and PV generation.
