A Quantum-Driven Time (QDT) Quantization of the Taub Cosmology
  We present here an application of a new quantization scheme. We quantize the Taub cosmology by quantizing only the anisotropy parameter $\beta$ and imposing the super-Hamiltonian constraint as an expectation-value equation to recover the relationship between the scale factor $\Omega$ and the time $t$. This approach appears to avoid the problem of time. (Paper to appear in the Seventh Marcel Grossmann Conference Proceedings.)
