Creating Collaboration in Economic Development
No full textAs the effects of globalization become more apparent and regions continue to emerge as the functional unit of international economic competition, many areas have engaged in regional visioning processes in order to create more unified and large-scale approaches to economic development and other planning-related issues. Successful regional visioning processes and the initiatives that are spurred by them encourage strong involvement on the part of both the public and private sectors – business leaders, elected officials, government agencies, and residents. Successful regional efforts have engaged a wide variety of stakeholders to create a balanced process with a variety of resources.
Upstate Reality Check, a regional visioning exercise comprising 10 counties in the Upstate of South Carolina, was held on April 8, 2009. More than 370 participants worked together to create a variety of possible scenarios to accommodate the significant population growth that is expected in the Upstate in coming years. Now, as the next steps process begins to move forward, a newly formed organization known as Ten at the Top will work on a variety of projects and collaborative efforts in this region.
This paper developed recommendations for future economic development actions for the region using the input of a number of economic development leaders in the Upstate and four case studies of organizations that have addressed economic development from a regional perspective based on increased regional collaboration. The case studies included the West Michigan Strategic Alliance, Central Florida’s MyRegion, Envision Utah, and Vision North Texas. Recommendations for future action include: engage the business community; work closely with news media; convene a group of supportive elected officials; create a series of ‘regional conversations’; create a set of regional indicators; explore grants and funding opportunities; develop a sourcebook to assist public agencies; utilize existing networks; and identify potential partnerships

Dual control of fault intersections on stop-start rupture in the 2016 Central Italy seismic sequence
No full textLarge continental earthquakes necessarily involve failure of multiple faults or segments. But these same critically-stressed systems sometimes fail in drawn-out sequences of smaller earthquakes over days or years instead. These two modes of failure have vastly different implications for seismic hazard and it is not known why fault systems sometimes fail in one mode or the other, or what controls the termination and reinitiation of slip in protracted seismic sequences. A paucity of modern observations of seismic sequences has hampered our understanding to-date, but a series of three Mw>6earthquakes from August to November 2016 in Central Italy represents a uniquely well-observed example. Here we exploit a wealth of geodetic, seismological and field data to understand the spatio-temporal evolution of the sequence. Our results suggest that intersections between major and subsidiary faults controlled the extent and termination of rupture in each event in the sequence, and that fluid diffusion, channelled along these same fault intersections, may have also determined the timing of rupture reinitiation. This dual control of subsurface structure on the stop-start rupture in seismic sequences may be common; future efforts should focus on investigating its prevalence
Surface faulting during the August 24, 2016, central Italy earthquake (Mw 6.0): Preliminary results
No full textWe present some preliminary results on the mapping of coseismically-induced ground ruptures following the Aug. 24, 2016, Central Italy earthquake (Mw 6.0). The seismogenic source, as highlighted by InSAR and seismological data, ruptured across two adjacent structures: the Mt. Vettore and Laga faults. We collected field data on ground breaks along the whole deformed area and two different scenarios of on-fault coseismic displacement arise from these observations. To the north, along the Mt. Vettore fault, surface faulting can be mapped quite continuously along a well-defined fault strand while such features are almost absent to the south, along the Laga fault, where flysch-like marly units are present. A major lithological control affects the surface expression of faulting, resulting in a complex deformation pattern
