Occupational therapists' perceptions of predischarge home assessments with older adults in acute care
Predischarge occupational therapy home assessments are routinely performed with older adults in Europe, Australia and North America. Their primary aim is to facilitate a timely and safe discharge from hospital. However, there is a lack of published research on this topic, especially studies exploring occupational therapists' perceptions of home assessments. The paper aims to redress this by describing occupational therapists' perceptions of predischarge occupational therapy home assessments with older adults in acute care.
All occupational therapists who undertook home assessments in an acute care hospital with older adults during the duration of the study period were invited to complete a reflective diary. In total, 15 reflective diaries were completed by six therapists. The data were analysed using thematic content analysis.
The findings suggest that home assessments were carried out because of mobility or environmental concerns. Satisfaction and dissatisfaction with the outcome of the home assessment were related to the incidents that occurred during the assessment. Some of the occupational therapists' anxieties were related to the older adults' level of functioning or ill health, and the older adults' own concerns did have an impact upon the therapists' expectations of the home assessment process
Field-Induced Magnetic and Structural Domain Alignment in PrO2
We present a neutron diffraction study of the magnetic structure of single
crystal PrO2 under applied fields of 0-6 T. As the field is increased, changes
are observed in the magnetic Bragg intensities. These changes are found to be
irreversible when the field is reduced, but the original intensities can be
recovered by heating to T > 122 K, then re-cooling in zero field. The
antiferromagnetic ordering temperature TN = 13.5 K and the magnetic periodicity
are unaffected by the applied field. We also report measurements of the
magnetic susceptibility of single crystal PrO2 under applied fields of 0-7 T.
These show strong anisotropy, as well as an anomaly at T = 122 +/- 2 K which
coincides with the temperature TD = 120 +/- 2 K at which a structural
distortion occurs. For fields applied along the [100] direction the
susceptibility increases irreversibly with field in the temperature range TN <
T < TD. However, for fields along [110] the susceptibility is independent of
field in this range. We propose structural domain alignment, which strongly
influences the formation of magnetic domains below TN, as the mechanism behind
these changes.Comment: 11 pages, 13 figures, 5 tables. Minor typographical changes in v

The Interaction between the ISM and Star Formation in the Dwarf Starburst Galaxy NGC 4214
We present the first interferometric study of the molecular gas in the
metal-poor dwarf starburst galaxy NGC 4214. Our map of the 12CO(1-0) emission,
obtained at the OVRO millimeter array, reveals an unexpected structural wealth.
We detected three regions of molecular emission in the north-west (NW),
south-east (SE) and centre of NGC 4214 which are in very different and distinct
evolutionary stages (total molecular mass: 5.1 x 10^6 M_sun). These differences
are apparent most dramatically when the CO morphologies are compared to optical
ground based and HST imaging: massive star formation has not started yet in the
NW region; the well-known starburst in the centre is the most evolved and star
formation in the SE complex started more recently. We derive a star formation
efficiency of 8% for the SE complex. Using high--resolution VLA observations of
neutral hydrogen HI and our CO data we generated a total gas column density map
for NGC 4214 (HI + H_2). No clear correlation is seen between the peaks of HI,
CO and the sites of ongoing star formation. This emphasizes the irregular
nature of dwarf galaxies. The HI and CO velocities agree well, so do the
H-alpha velocities. In total, we cataloged 14 molecular clumps in NGC 4214. Our
results from a virial mass analysis are compatible with a Galactic CO-to-H_2
conversion factor for NGC 4214 (lower than what is usually found in metal-poor
dwarf galaxies).Comment: accepted for publication in the AJ (February 2001), full ps file at:

Independent registration for naturopaths and herbalists in Australia: The coming of age of an ancient profession in contemporary healthcare
Recent changes in the healthcare landscape in Australia have prompted renewed debate regarding the most appropriate regulatory model for naturopaths and herbalists. Numerous government reports have recommended independent statutory regulation yet naturopaths and Western herbalists are yet to be included in the National Registration and Accreditation Scheme. This has left professional associations to carry the administrative burden and manage the conflicting interests of practitioner regulation and professional advocacy. The outcome of this self-regulatory model has damaged advancement of these professions through limiting the scope of professional associations to promote the value of practitioners within contemporary healthcare. It has also left naturopaths and Western herbalists vulnerable to health policy reform which impact on unregistered practitioners. In response, an independent registration body, the Australian Register of Naturopaths and Herbalists (ARONAH) has been established which mirrors the NRAS process and offers legitimacy to the professions whilst also safeguarding the public. This paper outlines: the history of the registration debate in Australia; the scope and role of ARONAH; the relationship between ARONAH and the existing professional associations and the rationale underpinning important standards and guidelines developed by ARONAH for its members. © National Herbalists Association of Australia 2013
Spin gaps and magnetic structure of NaxCoO2
We present two experiments that provide information on spin anisotropy and
the magnetic structure of NaxCoO2. First, we report low-energy neutron
inelastic scattering measurements of the zone-center magnetic excitations in
the magnetically ordered phase of Na0.75CoO2. The energy spectra suggest the
existence of two gaps, and are very well fitted by a spin-wave model with both
in-plane and out-of-plane anisotropy terms. The gap energies decrease with
increasing temperature and both gaps are found to have closed when the
temperature exceeds the magnetic ordering temperature T_m~22 K. Secondly, we
present neutron diffraction studies of Na0.85CoO2 with a magnetic field applied
approximately parallel to the c axis. For fields in excess of ~8T a magnetic
Bragg peak was observed at the (0,0,3) position in reciprocal space. We
interpret this as a spin-flop transition of the A-type antiferromagnetic
structure, and we show that the spin-flop field is consistent with the size of
the anisotropy gap.Comment: 9 pages, 7 figure
Shot Noise Suppression in Avalanche Photodiodes
We identify a new shot noise suppression mechanism in a thin (~100 nm)
heterostructure avalanche photodiode. In the low-gain regime the shot noise is
suppressed due to temporal correlations within amplified current pulses. We
demonstrate in a Monte Carlo simulation that the effective excess noise factors
can be <1, and reconcile the apparent conflict between theory and experiments.
This shot noise suppression mechanism is independent of known mechanisms such
as Coulomb interaction, or reflection at heterojunction interfaces.Comment: Phys. Rev. Lett., accepted for publicatio
Cooperative Jahn-Teller Distortion in PrO2
We report neutron diffraction data on single crystal PrO2 which reveal a
cooperative Jahn-Teller distortion at TD = 120 +/- 2 K. Below this temperature
an internal distortion of the oxygen sublattice causes the unit cell of the
crystallographic structure to become doubled along one crystal axis. We discuss
several possible models for this structure. The antiferromagnetic structure
below TN = 13.5 K is found to consist of two components, one of which shares
the same doubled unit cell as the distorted crystallographic structure. We also
present measurements of the magnetic susceptibility, the specific heat capacity
and the electrical conductivity of PrO2. The susceptibility data show an
anomaly at a temperature close to TD. From the specific heat capacity data we
deduce that the ground state is doubly degenerate, consistent with a distortion
of the cubic local symmetry. We discuss possible mechanisms for this. The
conductivity shows an activated behaviour with an activation energy Ea = 0.262
+/- 0.003 eV.Comment: 12 pages, 14 figures, 2 tables. Additional suggested structure in v
