A Novel Vision Zero Leadership Training Model to Support Collaboration and Strategic Action Planning.

While collaboration and cooperation are regarded as foundational to Vision Zero (VZ) and Safe Systems initiatives, there is little guidance on structuring VZ collaboration, conducting collaborative goal setting, and aligning tangible action across organizations. As part of a larger VZ mutual learning model, we developed a VZ Leadership Team Institute to support communities in collaborative VZ strategic planning and goal setting. The purpose of this paper is to describe the development and evaluation of the Institute, which can serve as a foundation for other initiatives seeking to move VZ planning and implementation forward in a collaborative, systems-aware manner.

Cell Proliferation and Collective Cell Migration During Zebrafish Lateral Line System Development Are Regulated by Ncam/Fgf-Receptor Interactions.

The posterior lateral line system (pLLS) of aquatic animals comprises small clustered mechanosensory organs along the side of the animal. They develop from proneuromasts, which are deposited from a migratory primordium on its way to the tip of the tail. We here show, that the Neural Cell Adhesion Molecule Ncam1b is an integral part of the pathways initiating and regulating the development of the pLLS in zebrafish.

Systems thinking in the context of road safety: Can systems tools help us realize a true "Safe Systems" approach?

Purpose Of Review: Road traffic injuries are one of the leading causes of death in the U.S. and globally.

Integrating complex systems science into road safety research and practice, Part 2: applying systems tools to the problem of increasing pedestrian death rates.

Objectives: To provide a specific example of how systems dynamics tools can increase understanding of stakeholder 'mental models' and generate robust systems-based hypotheses about the escalating problem of rising pedestrian death rates in the USA.

Methods: We designed and facilitated two group model building (GMB) workshops. Participants generated causal loop diagrams (CLDs) individually and in small groups to explore hypotheses concerning time-dynamic interacting factors underlying the increasing rates of pedestrian deaths.

Diverse school community engagement with the North Carolina active routes to school project: a diffusion study.

Background: Schools located in rural parts of the United States and North Carolina have benefited proportionally less from the federal Safe Routes to School (SRTS) program than their more urban counterparts. We investigated whether and how diverse elementary and middle school communities throughout North Carolina have engaged in a SRTS-inspired, multi-sectoral initiative called the Active Routes to School (ARTS) project over the course of 5 years (2013 through 2017).

Methods: Analyses included a study sample of 2602 elementary and middle schools in North Carolina, 853 that participated in the ARTS project over the five-year study period and 1749 that had not.
