Establishment and characterisation of an open mini-thoracotomy surgical approach to an ovine thoracic spine fusion model

Background A large animal model is required for assessment of minimally invasive, tissue engineering based approaches to thoracic spine fusion, with relevance to deformity correction surgery for human adolescent idiopathic scoliosis. Here we develop a novel open mini–thoracotomy approach in an ovine model of thoracic interbody fusion which allows assessment of various fusion constructs, with a focus on novel, tissue engineering based interventions. Methods The open mini-thoracotomy surgical approach was developed through a series of mock surgeries, and then applied in a live sheep study. Customized scaffolds were manufactured to conform with intervertebral disc space clearances required of the study. Twelve male Merino sheep aged 4 to 6 years and weighing 35 – 45 kg underwent the abovementioned procedure and were divided into two groups of six sheep at survival timelines of 6 and 12 months. Each sheep underwent a 3-level discectomy (T6/7, T8/9 and T10/11) with randomly allocated implantation of a different graft substitute at each of the three levels; (i) polycaprolactone (PCL) based scaffold plus 0.54μg rhBMP-2, (ii) PCL-based scaffold alone or (iii) autograft. The sheep were closely monitored post- operatively for signs of pain (i.e. gait abnormalities/ teeth gnawing/ social isolation). Fusion assessments were conducted post-sacrifice using Computed Tomography and hard-tissue histology. All scientific work was undertaken in accordance with the study protocol has been approved by the Institute's committee on animal research. Results. All twelve sheep were successfully operated on and reached the allotted survival timelines, thereby demonstrating the feasibility of the surgical procedure and post-operative care. There were no significant complications and during the post-operative period the animals did not exhibit marked signs of distress according to the described assessment criteria. Computed Tomographic scanning demonstrated higher fusion grades in the rhBMP-2 plus PCL-based scaffold group in comparison to either PCL-based scaffold alone or autograft. These results were supported by histological evaluation of the respective groups. Conclusion. This novel open mini-thoracotomy surgical approach to the ovine thoracic spine represents a safe surgical method which can reproducibly form the platform for research into various spine tissue engineered constructs (TEC) and their fusion promoting properties.

Empirical modelling of the relationship between bus and car speeds on signalised urban networks

Vehicle speed is an important attribute for the utility of a transport mode. The speed relationship between multiple modes of transport is of interest to the traffic planners and operators. This paper quantifies the relationship between bus speed and average car speed by integrating Bluetooth data and Transit Signal Priority data from the urban network in Brisbane, Australia. The method proposed in this paper is the first of its kind to relate bus speed and average car speed by integrating multi-source traffic data in a corridor-based method. Three transferable regression models relating not-in-service bus; in-service bus during peak; and in-service bus during off peak periods with average car are proposed. The models are cross-validated and the interrelationships are significant

Open up the building : architectural relevance of building-users and their participations

As buildings have become more advanced and complex, our ability to understand how they are operated and managed has diminished. Modern technologies have given us systems to look after us but it appears to have taken away our say in how we like our environment to be managed. The aim of this paper is to discuss our research concerning spaces that are sensitive to changing needs and allow building-users to have a certain level of freedom to understand and control their environment. We discuss why, what we call the Active Layer, is needed in modern buildings; how building inhabitants are to interact with it; and the development of interface prototypes to test consequences of having the Active Layer in our environment.

Differences in Epidural and Analgesic Use in Patients with Apparent Stage I Endometrial Cancer treated by open versus laparoscopic surgery: results from the randomised LACE trial

Objectives: We compared post-operative analgesic requirements between women with early stage endometrial cancer treated by total abdominal hysterectomy (TAH) or total laparoscopic hysterectomy (TLH). Methods: 760 patients with apparent stage I endometrial cancer were treated in the international, multicentre, prospective randomised trial (LACE) by TAH (n=353) or TLH (n=407) (2005-2010). Epidural, opioid and non-opioid analgesic requirements were collected until ten months after surgery. Results: Baseline demographics and analgesic use were comparable between treatment arms. TAH patients were more likely to receive epidural analgesia than TLH patients (33% vs 0.5%, p<0.001) during the early postoperative phase. Although opioid use was comparable in the TAH vs TLH groups during postoperative 0-2 days (99.7% vs 98.5%, p 0.09), a significantly higher proportion of TAH patients required opioids 3-5 days (70% vs 22%, p<0.0001), 6-14 days (35% vs 15%, p<0.0001), and 15-60 days (15% vs 9%, p 0.02) post-surgery. Mean pain scores were significantly higher in the TAH versus TLH group one (2.48 vs 1.62, p<0.0001) and four weeks (0.89 vs 0.63, p 0.01) following surgery. Conclusion: Treatment of early stage endometrial cancer with TLH is associated with less frequent use of epidural, lower post-operative opioid requirements and better pain scores than TAH.

Open educational resources in China : a governmentality analysis

Using a sociological approach, this study examines China’s reform of open educational resources (OER), which has prompted significant changes to the nation’s higher education sector. Through an analysis of the policy processes that have driven the reform, this study demonstrates that the reform has involved and brought significant changes to its participants as resource administrators, providers, and receivers. By using governmentality as a poststructuralist analytical framework, this study shows the particular ways in which the reform process has been governed and the ways in which the governing practices have changed the conduct of higher education. The study reveals the power relations exercised through the reform and offers a critique of China’s higher education sector.

The development of a naturalistic car following model for assessing managed motorway systems' safety effects

This thesis highlights the limitations of the existing car following models to emulate driver behaviour for safety study purposes. It also compares the capabilities of the mainstream car following models emulating driver behaviour precise parameters such as headways and Time to Collisions. The comparison evaluates the robustness of each car following model for safety metric reproductions. A new car following model, based on the personal space concept and fish school model is proposed to simulate more precise traffic metrics. This new model is capable of reflecting changes in the headway distribution after imposing the speed limit form VSL systems. This research facilitates assessing Intelligent Transportation Systems on motorways, using microscopic simulation.

Addressing Public and Private Issues in a Virtual Ethnography Study of an Open Online Community: a Reflective Paper

This paper discusses the ethical consequences of employing virtual ethnography to observe human behaviour in open online communities. In this paper, we discuss the nature of the online community being studied as well as the lessons learned from both literature and also the ethical clearance application process undertaken by the research team. A key finding was that despite the community being open to the public, generally community members expected the research team to employ strategies similar to those required when dealing with a private community.

A retrospective cohort investigation of active range of motion within one week of open reduction and internal fixation of distal radius fractures

Distal radius fractures stabilized by open reduction internal fixation (ORIF) have become increasingly common. There is currently no consensus on the optimal time to commence range of motion (ROM) exercises post-ORIF. A retrospective cohort review was conducted over a five-year period to compare wrist and forearm range of motion outcomes and number of therapy sessions between patients who commenced active ROM exercises within the first seven days and from day eight onward following ORIF of distal radius fractures. One hundred and twenty-one patient cases were identified. Clinical data, active ROM at initial and discharge therapy assessments, fracture type, surgical approaches, and number of therapy sessions attended were recorded. One hundred and seven (88.4%) cases had complete datasets. The early active ROM group (n = 37) commenced ROM a mean (SD) of 4.27 (1.8) days post-ORIF. The comparator group (n = 70) commenced ROM exercises 24.3 (13.6) days post-ORIF. No significant differences were identified between groups in ROM at initial or discharge assessments, or therapy sessions attended. The results from this study indicate that patients who commenced active ROM exercises an average of 24 days after surgery achieved comparable ROM outcomes with similar number of therapy sessions to those who commenced ROM exercises within the first week.

Sejong Park's Birthday Boy and Korean-Australian encounters

This chapter focuses on some of the flows of film work between Australia and South Korea and some of the roles taken by Australians in the performance (and particularly the sound) of Koreanness in different film contexts. We explore Korean-Australian collaboration on film, through case studies of Sejong Park's Oscar nominated short animated film Birthday Boy (2004) and two Korean feature films - Musa (Kim Sung-su, 2001) and Shadowless Sword (Kim Young-jun, 2005) - for which Australian firms provided sound post-production services. We show how these films instanciate and expand Korean, Australian, diasporic and transnational filmmaking.

Review : "Birthday Boy" -- Sejong Park

Synopsis and review of Sejong Park's film Birthday Boy. Includes credits. Birthday Boy has won over 40 awards at film festivals around the world including Best Animated Short at the prestigious SIGGRAPH Computer Animation Festival in 2004 which qualified the film for the 2005 Academy Awards even before Park and fellow students had graduated from the Australian Film, Television and Radio School (AFTRS). It was subsequently nominated for the Oscar for Best Animated Short Film, losing to another extraordinary short, Chris Landreth’s tribute to pioneering Canadian animator Ryan Larkin, Ryan. Other awards include the Prix Jean-Luc Xiberras at the Annecy International Animated Film Festival in 2005 (which had a special focus on Korea) and Best Short Animation at the 2005 BAFTA awards. It has screened at over 100 film festivals around the world, and is the most awarded film in the almost forty year history of the AFTRS...

Open and networked initiatives and the digital transformation of academic publishing in China

Many aspects of China's academic publishing system differ from the systems found in liberal market based economies of the United States, Western Europe and Australia. A high level of government intervention in both the publishing industry and academia and the challenges associated with attempting to make a transition from a centrally controlled towards a more market based publishing industry are two notable differences; however, as in other countries, academic communities and publishers are being transformed by digital technologies. This research explores the complex yet dynamic digital transformation of academic publishing in China, with a specific focus of the open and networked initiatives inspired by Web 2.0 and social media. The thesis draws on two case studies: Science Paper Online, a government-operated online preprint platform and open access mandate; and New Science, a social reference management website operated by a group of young PhD students. Its analysis of the innovations, business models, operating strategies, influences, and difficulties faced by these two initiatives highlights important characteristics and trends in digital publishing experiments in China. The central argument of this thesis is that the open and collaborative possibilities of Web 2.0 inspired initiatives are emerging outside the established journal and monograph publishing system in China, introducing innovative and somewhat disruptive approaches to the certification, communication and commercial exploitation of knowledge. Moreover, emerging publishing models are enabling and encouraging a new system of practising and communicating science in China, putting into practice some elements of the Open Science ethos. There is evidence of both disruptive change to old publishing structures and the adaptive modification of emergent replacements in the Chinese practice. As such, the transformation from traditional to digital and interactive modes of publishing, involves both competition and convergence between new and old publishers, as well as dynamics of co-evolution involving new technologies, business models, social norms, and government reform agendas. One key concern driving this work is whether there are new opportunities and new models for academic publishing in the Web 2.0 age and social media environment, which might allow the basic functions of communication and certification to be achieved more effectively. This thesis enriches existing knowledge of open and networked transformations of scholarly publishing by adding a Chinese story. Although the development of open and networked publishing platforms in China remains in its infancy, the lessons provided by this research are relevant to practitioners and stakeholders interested in understanding the transformative dynamics of networked technologies for publishing and advocating open access in practice, not only in China, but also internationally.
