This paper reports results of determining changes in content coverage of the Proceedings of the National Academy of Science (PNAS). Dominant keywords were extracted to visualize major research topics and their evolution in the 20-year time frame. Two time slices namely 1995 and 2001 are examined in detail. Latent Semantic Analysis [6] was applied to determine the space of semantically similar d...
Workers' compensation provides medical care and income maintenance protection to workers disabled from work-related injury or illness. This program is of considerable interest to the Social Security Administration (SSA) from several perspectives. For example, since 1965 Social Security Disability Insurance (DI) benefits and workers' compensation payments have been integrated. Information on the...
of n linearly independent vectors b1, . . . ,bn ∈ Rm in m-dimensional Euclidean space. For computational purposes, the lattice vectors b1, . . . ,bn are often assumed to have integer (or rational) entries, so that the lattice can be represented by an integer matrix B = [b1, . . . ,bn] ∈ Zm×n (called basis) having the generating vectors as columns. Using matrix notation, lattice points in L(B) c...
Elite mobilizations play a key role in shaping the contours of social institutions. Prior research has demonstrated that mobilizations and the resulting struggles between competing elites shape the social structure of markets (Fligstein 1996), corporate governance regimes (Davis and Thompson 1994), and organizations (Fligstein 1990; Zald and Berger 1978).
