Rosenbloom, Iowa State University, UNITED STATES The results provide a new perspective on the functional economic geography of the United States from a megaregion perspective, and shed light on the old geographic problem of the division of space into areal units.Ĭitation: Dash Nelson G, Rae A (2016) An Economic Geography of the United States: From Commutes to Megaregions. We discuss how choices about input parameters and scale of analysis can lead to different results, and stress the importance of comparing computational results with “common sense” interpretations of geographic coherence. We compare a method which uses a visual heuristic for understanding areal aggregation to a method which uses a computational partitioning algorithm, and we reflect upon the strengths and limitations of both. This paper uses a data set of more than 4,000,000 commuter flows as the basis for an empirical approach to the identification of such megaregions. Instructions for what to do if an individual sees the signal, and how to check-in safely, were also created.The emergence in the United States of large-scale “megaregions” centered on major metropolitan areas is a phenomenon often taken for granted in both scholarly studies and popular accounts of contemporary economic geography. The signal has been recognized by over 40 organizations across Canada and the United States as a useful tool to help combat domestic violence.Īddressing concerns that abusers may become aware of such a widespread online initiative, the Canadian Women's Foundation and other organizations clarified that this signal is not "something that's going to save the day," but rather a tool someone could use to get help. It received widespread praise from local, national, and international news organizations for helping provide a modern solution to the issue of a rise in domestic violence cases. The Signal for Help was first introduced in Canada by the Canadian Women's Foundation on April 14, 2020, and on Apin the United States by the Women's Funding Network (WFN). It was intentionally designed as a single continuous hand movement, rather than a sign held in one position, that could be made easily visible. The signal is performed by holding your hand up with your thumb tucked into your palm, then folding your fingers down, symbolically trapping your thumb in your fingers. It was originally created as a tool to combat the rise in domestic violence cases around the world as a result of the self-isolation measures related to the COVID-19 pandemic. The Signal for Help (or the Violence at Home Signal for Help) is a single-handed gesture that can be used by an individual to alert others that they feel threatened and need help over a video call, or in-person.
