IC 3418: Star Formation in a Turbulent Wake

Galaxy Evolution Explorer observations of IC 3418, a low surface brightness galaxy in the Virgo Cluster, revealed a striking 17 kpc UV tail of bright knots and diffuse emission. H alpha imaging confirms that star formation is ongoing in the tail. IC 3418 was likely recently ram pressure stripped on its first pass through Virgo. We suggest that star formation is occurring in molecular clouds that formed in IC 3418's turbulent stripped wake. Tides and ram pressure stripping (RPS) of molecular clouds are both disfavored as tail formation mechanisms. The tail is similar to the few other observed star-forming tails, all of which likely formed during RPS. The tails' morphologies reflect the forces present during their formation and can be used to test for dynamical coupling between molecular and diffuse gas, thereby probing the origin of the star forming molecular gas.Comment: 5 pages, 4 figure

Organizing Venture Capital: The Rise and Demise of American Research & Development Corporation, 1946–1973

While venture capital (VC) has become an important element of the twentiethcentury US innovation system, few studies have systematically examined the origins and evolution of this financial institution. We take a step in this direction by analyzing the evolution of the early and influential VC firm, American Research & Development Corporation (ARD), in the period that it was independent from 1946 to 1973. We place the creation and subsequent evolution of ARD within its historical context and show how it was an innovation by Boston-area civic elites. Using new historical data, we examine the evolution of ARD’s practices over time. We argue that ARD’s funding model constrained its functioning as a venture capital firm and contributed to its demise. ARD was a pioneering organization whose business model ultimately failed as a newer organizational model, the limited partnership, was created and had a better fit with the business environment. Nevertheless, ARD has had a lasting imprint on the practice of modern venture capital

Computer and Internet Use by Great Plains Farmers

We use data from a 2001 survey of Great Plains farmers to explore the adoption, usage patterns, and perceived benefits of computers and the Internet. Our adoption results suggest that exposure to the technology through college, outside employment, friends, and family is ultimately more influential than farmer age and farm size. Notably, about half of those who use the Internet for farm-related business report zero economic benefits from it. Whether a farmer perceives that the Internet generates economic benefits depends primarily on how long the farmer has used the Internet for farm business and for what purposes.Farm Management, Research and Development/Tech Change/Emerging Technologies,
