White masculinity: Jan Smuts, race and the South African war.

NO SINGLE FIGURE DID MORE to shape South Africa in the first fifty years of the twentieth century, or to establish it in the international imagination, than Jan Christiaan Smuts. Widely recognised in his day as an exceptional scholar, soldier, and scientist, he was also South Africa’s most outstanding white statesman in the twentieth century, the equivalent in terms of international stature the...

Jan Smuts and Personality Theory: The Problem of Holism in Psychology

∗ Jan

We formulate a complete path integral bosonization procedure for any fermionic theory in two dimensions. The classical action of the bosons in the bosonized theory is −i times the logarithm of the Jacobian of a local chiral transformation, with the boson fields as transformation parameters. Three examples, the Schwinger model, the massive Thirring model and massive non-Abelian bosonization, are...

Smooth objective functionals for seismic velocity inversion ∗ Christiaan

In seismic inverse scattering, the data are divided into subsets, each of which is used to reconstruct the medium discontinuities by linearized inversion. The reconstructions depend on an a priori unknown, smoothly varying background medium (velocity model). The semblance principle, which states that the images must agree, is the basis for the reconstruction of the background medium. Several es...

Online content have become an important medium to disseminate information and express opinions. With the proliferation of online document collections, users are faced with the problem of missing the big picture in a sea of irrelevant and/or diverse content. In this thesis, we addresses the problem of information organization of online document collections, and provide algorithms that create a s...
