The van der Waals picture focuses on the differing roles of the strong short-ranged repulsive intermolecular forces and the longer ranged attractions in determining the structure and dynamics of dense fluids and solids. According to this physical picture, the attractive interactions help fix the volume of the system, but the arrangements and motions of(More)
This paper describes an in-depth, qualitative exploration of helping behavior among software engineers doing the same type of work in the U.S. and India. Consistent with research describing American culture as more individualist and Indian culture as more collectivist, we find that engineers at the American site provide help only to those from whom they(More)
We separate double stranded lambda phage DNA by applying a fixed force at a constant temperature ranging from 15 to 50 degrees C, and measure the minimum force required to separate the two strands. The measurements also offer information on the free energy of double stranded DNA (dsDNA) at temperatures where dsDNA does not thermally denature in the absence(More)
We examine the contagion processes whereby practices originating in one organizational population spread into and diffuse within a second. We theorize that " endemic " innovations native to one population spread to other populations through two distinct forms of contagion. We test this argument by observing information technology firms' adoption of(More)
Under constant applied force, the separation of double-stranded DNA into two single strands is known to proceed through a series of pauses and jumps. Given experimental traces of constant-force unzipping, we present a method whereby the locations of pause points can be extracted in the form of a pause point spectrum. A simple theoretical model of DNA(More)
