A Commonwealth Religious Discrimination Act for Australia?
There have been a number of attempts to create a constitutional bill of rights in Australia, but all have failed. The most recent exploration of the idea of a constitutional bill of rights by the Rudd government in 2010 stalled because of church opposition. Yet Australia has embraced international norms outlawing racial and sexual discrimination passed as ordinary legislation using the Commonwealth’s external affairs power.
This paper discusses whether religious freedom is a norm sufficiently well established in international law that it could also be passed as ordinary legislation in Australia. It then investigates what an Australian religious freedom law might look like and whether it could be crafted so as to allay the church opposition which has shut down previous attempts to create a constitutional bill of rights
Slow Diffusive Gravitational Instability Before Decoupling
Radiative diffusion damps acoustic modes at large comoving wavenumber (k)
before decoupling (``Silk damping''). In a simple WKB analysis, neglecting
moments of the temperature distribution beyond the quadrupole, damping appears
in the acoustic mode as a term of order ik^2/(taudot) where taudot is the
scattering rate per unit conformal time. Although the Jeans instability is
stabilized on scales smaller than the adiabatic Jeans length, I show that the
medium is linearly unstable to first order in (1/taudot) to a slow diffusive
mode. At large comoving wavenumber, the characteristic growth rate becomes
independent of spatial scale and constant: (t_{KH}a)^-1 ~ (128 pi G/9 kappa_T
c)(rho_m/rho_b), where "a" is the scale factor, rho_m and rho_b are the matter
and baryon energy density, respectively, and kappa_T is the Thomson opacity.
This is the characteristic timescale for a fluid parcel to radiate away its
thermal energy content at the Eddington limit, analogous to the Kelvin-Helmholz
(KH) time for a massive star or the Salpeter time for black hole growth.
Although this mode grows at all times prior to decoupling and on scales smaller
than the horizon, the growth time is long, about 100 times the age of the
universe at decoupling. Thus, it modifies the density and temperature
perturbations on small scales only at the percent level. The physics of this
mode is already accounted for in the popular codes CMBFAST and CAMB, but is
typically neglected in analytic studies of the growth of primordial
perturbations. This work clarifies the physics of this instability in the epoch
before decoupling, and emphasizes that the universe is formally unstable on
scales below the horizon, even in the limit of large taudot. Analogous
instabilities at yet earlier epochs are also mentioned. (Abridged)Comment: 6 pages, 1 figure, emulateapj, comments welcom
Practices of Nurse Practitioners in Screening for Hepatitis C

MASTER OF SCIENCEThe purpose of this project was to determine both hepatitis C virus (HCV) screening rates and the percentage of cases diagnosed among adults born between 1945 and 1965 in a general practice clinic staffed by nurse practitioners (NPs). A descriptive study was conducted using a chart review of all patients born between 1945 and 1965 seen by NPs in a primary care clinic during a three month period of time. Data was collected on the total number of patients in the target group, those born between 1945 and 1965, as well as each patient’s gender, birth date, if screened for HCV, result of screening, and the reason for screening. Findings revealed that screening rates were suboptimal, with only six out of 178 patients in the target group having been screened for HCV. Age and gender did not appear to be a factor in whether or not a patient was screened
