The Historical Development of Easter-Southern Freight Rate Relationships
A method for creating and presenting video-recorded synchronized audiovisual stimuli at a high frame rate-which would be highly useful for psychophysical studies on, for example, just-noticeable differences and gating-is presented. Methods for accomplishing this include recording audio and video separately using an exact synchronization signal, editing the recordings and finding exact synchronization points, and presenting the synchronized audiovisual stimuli with a desired frame rate on a cathode ray tube display using MATLAB and Psychophysics Toolbox 3. The methods from an empirical gating study (Moradi, Lidestam, and Ronnberg, Frontiers in Psychology 4: 359, 2013) are presented as an example of the implementation of playback at 120 fps

Simultaneous optical polarimetry and X-ray observations of the magnetic CV CP Tuc (AX J2315--592)
CP Tuc (AX J2315--592) shows a dip in X-rays which lasts for approximately
half the binary orbit and is deeper in soft X-rays compared with hard X-rays.
It has been proposed that this dip is due to the accretion stream obscuring the
accretion region from view. If CP Tuc was a polar, as has been suggested, then
the length of such a dip would make it unique amongst polars since in those
polars in which a dip is seen in hard X-rays the dip lasts for only 0.1 of the
orbit. We present optical polarimetry and RXTE observations of CP Tuc which
show circular polarisation levels of ~10 per cent and find evidence for only
one photometric period. These data confirm CP Tuc as a polar. Our modelling of
the polarisation data imply that the X-ray dip is due to the bulk of the
primary accretion region being self-eclipsed by the white dwarf. The energy
dependence of the dip is due to a combination of this self-eclipse and also the
presence of an X-ray temperature gradient over the primary accretion region.Comment: 6 pages, accepted for publication in MNRA
Numbers Don\u27t Tell the Whole Story: A Case Study of an Alternative Pathway to Tertiary Studies
This case study responds to the debate over
βtoxic teachersβ, tertiary entry ranking and
access to university. Implications for federal
and state policy are proposed. For 22 years
Avondale College of Higher Education has been
operating a tertiary pathway course designed
to widen access to higher education for nontraditional
applicants. The course, now known
as the Diploma of General Studies [DGS], has
been accredited as a 2-year higher education
sector diploma since 1995. Thus far, just over
1000 students have spent at least one semester
in the diploma. Not one has opted to complete
the diploma; instead students use it as a
pathway to a higher award, mostly Avondale
bachelor degrees in education, nursing, arts,
theology, business and occasionally science.
To date, 300 former pathway students have
completed an Avondale degree, and a further
250 are currently enrolled. DGS students
commence with Year 12 ranks (UAI, ENTER,
TER, now ATAR) ranging from 30 or less to
around 60; however, many have no rank. For
those who complete an Avondale degree, there
is no correlation between rank and average
college grade. Those who engage with the
academic program do well, regardless of their
entry rank; and those who fail to engage do
poorly, regardless of their entry rank. A low
Year 12 rank does not tell an applicantβs whole
story. A semester in the DGS pathway course
can open a new world of academic opportunity.
Some DGS students have gone on to complete
post-graduate study. Teachers can confidently
advise Year 12 students with potential, but
low tertiary ranking, to consider the option of
alternative pathways to tertiary studies as these
can provide a positive opportunity to achieve
their aspirations
