Acupuncture and the Australian workers' compensation system : studies on the Chinese medicine profession's perceptions and interactions with the workers' compensation system and their treatment of work-related injuries
University of Technology, Sydney. Faculty of Science.The use of acupuncture by Chinese medicine (CM) practitioners has become an increasingly popular treatment modality of choice in Australia in the last four decades. Acupuncture is increasingly being used as part of an individual's health care strategy, with CM practitioners often integrated within a primary care context; they are being consulted on issues of both acute and chronic illness, as providers of treatment for musculoskeletal injury and as sources of lifestyle and dietary advice. As an extension of an individual's choice of treatment for their health has been their choice of treatment in work contexts where the individual as a 'worker', may have suffered an injury or illness during the course of their employment. Termed 'work-related injuries', this falls within the jurisdiction of the 'workers' compensation system' where the individual still retains the right to their choice of treatment(s).
Anecdotal reports from an Australian CM professional association and the New South Wales (NSW) workers' compensation industry indicates that acupuncture is being utilised in the Australian workers' compensation system; that injured workers are seeking acupuncture treatments from CM practitioners; while insurance companies are providing payments to CM practitioners on the workers behalf for acupuncture treatment. Where factual evidence for the use and integration of acupuncture was thought to exist, a preliminary search into the Australian workers' compensation system revealed a noticeable paucity of information on the use of acupuncture by CM practitioners. An extensive literature review was undertaken which identified no collated data or documented information in the available literature on the use of acupuncture by CM practitioners within the workers' compensation system beyond the anecdotal reports. In particular, no studies were located investigating the use of acupuncture as a treatment modality within the Australian workers' compensation system. Consequently, the use of acupuncture by CM practitioners to assist injured workers in the recovery of a work-related injury or illness is unknown.
Therefore, the primary aim of this thesis was to provide information and an understanding of the utilisation of acupuncture by CM practitioners within the workers' compensation system through a series of investigative studies. The present research is composed of two distinct but inter-related studies (termed Study 1 and Study 2). The aim of Study 1 was to obtain an overview of the CM profession's engagement with Australia's workers' compensation system and a consequent investigation into their perceptions of this system. Data were gathered on the following three areas:
• The proportion of CM practitioners engaging with the workers' compensation system as treatment providers of acupuncture to injured workers
• CM practitioners perceptions and views of this system, and
• To gather demographic profile of the CM practitioners in order to assist in contextualising the responses received with respect to a respondent's state and/or territory of residence.
Study 2 was an investigation into the demographic profile of injured workers who received acupuncture from CM practitioners as part of their workers' compensation claim. This was achieved through a retrospective analysis of workers' compensation claims data held by one Scheme Agent in NSW. The primary aims of Study 2 were:
• To gather a profile of the injured workers who utilised acupuncture treatment
• Profile the work-related injuries treated with acupuncture (identified as occurring during the acute or chronic phase of the injury, the anatomical location of the injury treated, the mechanism and agency of the injury), and
• An analysis of the acupuncture treatment cost
Together, the two studies begin to address the lack of information that currently exists in the Australian workers' compensation system on the use of acupuncture by Chinese medicine practitioners in the treatment of work-related injuries.
The findings from Study 1 confirmed anecdotal reports that CM practitioners have been treating injured workers in Australia's workers' compensation system, with the first reported workers' compensation 'patient' treated in 1970 by a CM practitioner. Study 1 also found significant associations between a CM practitioner's State of residence, perceptions of the State based workers' compensation Scheme and the difficulties faced when engaging with these Schemes. These relationships were attributed to the varying levels of recognition given to acupuncture (as a treatment modality) and CM practitioners (as therapy providers).
The demographic information reported in Study 2 found injured workers from across the State of NSW had utilised acupuncture to assist in the recovery of a work-related injury. There was a preference by injured workers to obtain acupuncture treatments from nonmedical acupuncture practitioners versus registered medical practitioners. The findings showed over half of the injured workers also sought acupuncture treatments during the acute stage of an injury (that is, within three months of sustaining the injury) and presented with injuries predominantly located in the trunk and upper limb areas. Injured workers aged between the years of 30-49 used acupuncture more than any other age group, while men who sustained a work-place injury were found to utilise acupuncture more than women. The cost associated with acupuncture treatments per claim were also shown to be reasonable when compared to physiotherapy and chiropractic costs within the study database. Together, the findings from Study 1 and Study 2 showed an overall increase in the number of CM practitioners treating injured workers, particularly during the years 1994 to 2004. The studies provided concrete evidence that acupuncture has been used as a treatment by injured workers within the Australian workers' compensation.
In conclusion, the research presented in this thesis provides the first evidence for the systematic use of acupuncture by Chinese medicine practitioners within the Australian workers' compensation system. The continued use of acupuncture within Australia will most likely see a greater number of injured workers seeking acupuncture treatment to assist in the recovery of their work-related injury or illness. This will have implications for Australia's workers' compensation system when CM practitioners become registered in 2012 as part of the National Registration and Accreditation scheme for health professions. In effect, the findings of the studies are valuable to the professional associations (to identify topics of continuing professional education) and to educators (for developing further necessary subjects on 'professional issues' in relation to workers' compensation). The workers' compensation Schemes themselves can draw upon the findings and better develop systems, policy and procedures governing the utilisation of acupuncture by CM practitioners where at present none exist or where it exists in limited form, with the exception of Victoria. Besides noting a need for information, the development of 'education' can be more specifically directed towards topics that have a practice oriented outcome to assist CM practitioners to better engage with the workers' compensation system. This will benefit the workers' compensation Schemes themselves, ensure suitably qualified practitioners are providing the acupuncture treatments and ultimately, ensure the appropriate and timely treatment of injured workers
Scene Graph Generation by Iterative Message Passing
Understanding a visual scene goes beyond recognizing individual objects in
isolation. Relationships between objects also constitute rich semantic
information about the scene. In this work, we explicitly model the objects and
their relationships using scene graphs, a visually-grounded graphical structure
of an image. We propose a novel end-to-end model that generates such structured
scene representation from an input image. The model solves the scene graph
inference problem using standard RNNs and learns to iteratively improves its
predictions via message passing. Our joint inference model can take advantage
of contextual cues to make better predictions on objects and their
relationships. The experiments show that our model significantly outperforms
previous methods for generating scene graphs using Visual Genome dataset and
inferring support relations with NYU Depth v2 dataset.Comment: CVPR 201
Doped Mott insulators are insulators: hole localization in the cuprates
We demonstrate that a Mott insulator lightly doped with holes is still an
insulator at low temperature even without disorder. Hole localization obtains
because the chemical potential lies in a pseudogap which has a vanishing
density of states at zero temperature. The energy scale for the pseudogap is
set by the nearest-neighbour singlet-triplet splitting. As this energy scale
vanishes if transitions, virtual or otherwise, to the upper Hubbard band are
not permitted, the fundamental length scale in the pseudogap regime is the
average distance between doubly occupied sites. Consequently, the pseudogap is
tied to the non-commutativity of the two limits ( the on-site
Coulomb repulsion) and (the system size).Comment: 4 pages, 3 .eps file
Weakly supervised 3D Reconstruction with Adversarial Constraint
Supervised 3D reconstruction has witnessed a significant progress through the
use of deep neural networks. However, this increase in performance requires
large scale annotations of 2D/3D data. In this paper, we explore inexpensive 2D
supervision as an alternative for expensive 3D CAD annotation. Specifically, we
use foreground masks as weak supervision through a raytrace pooling layer that
enables perspective projection and backpropagation. Additionally, since the 3D
reconstruction from masks is an ill posed problem, we propose to constrain the
3D reconstruction to the manifold of unlabeled realistic 3D shapes that match
mask observations. We demonstrate that learning a log-barrier solution to this
constrained optimization problem resembles the GAN objective, enabling the use
of existing tools for training GANs. We evaluate and analyze the manifold
constrained reconstruction on various datasets for single and multi-view
reconstruction of both synthetic and real images
Dynamic analysis of multimesh-gear helicopter transmissions
A dynamic analysis of multimesh-gear helicopter transmission systems was performed by correlating analytical simulations with experimental investigations. The two computer programs used in this study, GRDYNMLT and PGT, were developed under NASA/Army sponsorship. Parametric studies of the numerical model with variations on mesh damping ratios, operating speeds, tip-relief tooth modifications, and tooth-spacing errors were performed to investigate the accuracy, application, and limitations of the two computer programs. Although similar levels of dynamic loading were predicted by both programs, the computer code GRDYNMLT was found to be superior and broader in scope. Results from analytical work were also compared with experimental data obtained from the U.S. Army's UH-60A Black Hawk 2240-kW (3000-hp) class, twin-engine helicopter transmission tested at the NASA Lewis Research Center. Good correlation in gear stresses was obtained between the analytical model simulated by GRDYNMLT and the experimental measurements. More realistic mesh damping can be predicted through experimental data correlation
Capacitors can radiate - some consequences of the two-capacitor problem with radiation
We fill a gap in the arguments of Boykin et al [American Journal of Physics,
Vol 70 No. 4, pp 415-420 (2002)] by not invoking an electric current loop (i.e.
magnetic dipole model) to account for the radiation energy loss, since an
obvious corollary of their results is that the capacitors should radiate
directly even if the connecting wires are shrunk to zero length. That this is
so is shown here by a direct derivation of capacitor radiation using an
oscillating electric dipole radiator model for the capacitors as well as the
alternative less widely known magnetic 'charge' current loop representation for
an electric dipole [see for example "Electromagnetic Waves" by S.A.Schlekunoff,
van Nostrand (1948)]. Implications for Electromagnetic Compliance (EMC) issues
as well as novel antenna designs further motivate the purpose of this paper.Comment: 5 Pages with No figure
SEGCloud: Semantic Segmentation of 3D Point Clouds
3D semantic scene labeling is fundamental to agents operating in the real
world. In particular, labeling raw 3D point sets from sensors provides
fine-grained semantics. Recent works leverage the capabilities of Neural
Networks (NNs), but are limited to coarse voxel predictions and do not
explicitly enforce global consistency. We present SEGCloud, an end-to-end
framework to obtain 3D point-level segmentation that combines the advantages of
NNs, trilinear interpolation(TI) and fully connected Conditional Random Fields
(FC-CRF). Coarse voxel predictions from a 3D Fully Convolutional NN are
transferred back to the raw 3D points via trilinear interpolation. Then the
FC-CRF enforces global consistency and provides fine-grained semantics on the
points. We implement the latter as a differentiable Recurrent NN to allow joint
optimization. We evaluate the framework on two indoor and two outdoor 3D
datasets (NYU V2, S3DIS, KITTI, Semantic3D.net), and show performance
comparable or superior to the state-of-the-art on all datasets.Comment: Accepted as a spotlight at the International Conference of 3D Vision

Vibration and noise analysis of a gear transmission system
This paper presents a comprehensive procedure to predict both the vibration and noise generated by a gear transmission system under normal operating conditions. The gearbox vibrations were obtained from both numerical simulation and experimental studies using a gear noise test rig. In addition, the noise generated by the gearbox vibrations was recorded during the experimental testing. A numerical method was used to develop linear relationships between the gearbox vibration and the generated noise. The hypercoherence function is introduced to correlate the nonlinear relationship between the fundamental noise frequency and its harmonics. A numerical procedure was developed using both the linear and nonlinear relationships generated from the experimental data to predict noise resulting from the gearbox vibrations. The application of this methodology is demonstrated by comparing the numerical and experimental results from the gear noise test rig
