Auto-regulating New Media
Using Foucault's (1977, 1978) notion of panoptic method of governmentality and looking at the case of Singapore's Internet policy, this paper attempts to expand on the idea-and ideals-of 'auto-regulation'(Lee, 2000, pp. 4-5; Lee & Birch, 2000). Auto-regulation, as I shall posit in this paper, provides a way for regulatory enforcement and surveillance to become sufficiently transparent and 'normalised' so that 'the exercise of power may be supervised by society as a whole'(Foucault, 1977, pp.207-208) rather than by a select group of policy and law enforcement officers, or civil society /activist groups
Pion Production Model - Connection between Dynamics and Quark Models
We discuss the difficulties in testing the hadron models by using the N^*
parameters extracted from the empirical amplitude analyses of the pi-N and
gamma-N reaction data. As an alternative or perhaps a more advantageous
approach, we present a Hamiltonian formulation that can relate the pion
production dynamics and the constituent quark models of N^* structure. The
application of the approach in investigating the Delta and N^*(S_{11})
excitations is reviewed. It is found that while the Delta excitation can be
described satisfactory, the pi-N scattering in S_{11} channel can not be
described by the constituent quark models based on either the
one-gluon-exchange or one-meson-exchange mechanisms. A phenomenological
quark-quark potential has been constructed to reproduce the S_{11} amplitude.Comment: 11 pages, 4 figures, to be published in Proceedings of NSTAR2000

Semiempirical calculation of deep levels: divacancy in Si
A study of the electronic levels associated with the divacancy in silicon is reported. The extended Huckel theory is shown to reproduce the band structure of silicon. The electronic levels of the divacancy are calculated by considering a periodic array of large unit cells each containing 62 atoms; a 64 atom perfect cell with two atoms removed to form the divacancy. The results are found to be in qualitative agreement with the results of EPR and infrared absorption measurements
