- Description: The aim of this experiment was to determine which cybersickness symptoms are associated with simulated motion, by comparing responses to the Simulated Sickness Questionnaire (SSQ) between a control and experimental condition. Using non-parametric statistical tests, we found that general discomfort, fatigue, headache, eyestrain, difficulty in focusing eyes, increased sweating, nausea, difficulty in concentrating, stomach awareness and blurred vision were significantly higher in a high simulated motion task compared with a low simulated task. The implications for preventing cybersickness in virtual environments are discussed. © 2009 IEEE.

- Description: Flexible operation of post-combustion CO2 capture (PCC) plants can improve efficiency through coordinating the balance between consumer demands for electricity and CO2 emission reductions. This strategy however, will impose process disturbances and the immediate and long term impact is unclear. There is a justified need for the development of accurate dynamic PCC models, as well as practical experience in dynamic operation of PCC pilot plants. This paper presents CSIRO PCC pilot plant data from the 2012 and 2013 dynamic campaigns using MEA solvent. The step-change approach to dynamic plant operation was implemented and the use of density meters to instantaneously measure CO2 loading instantaneously was investigated.

- Description: For some children with impairments, playing on a playground with other children, is seldom or never experienced. Accessible playgrounds have features which can give children with disabilities the opportunity to gain access to play so that they can be included in play with other children, including peers who do not have impairments. In this paper, qualitative data drawn from the views and perceptions of children is explored. Interpretation through reflection on this data attempts to make sense of the lived experience of participants in school and community playgrounds as they try to engage with supposedly accessible play equipment that can facilitate participation, yet also create unintentional barriers to play. The social model of disability, which suggests that disability is created by an unequal social relationship, together with the 'new' sociology of childhood is adopted as a way of viewing the relationship between children, disability and the playground environment. An argument is advanced for broader implications that affect children who use school and community playgrounds which need to be considered to enhance inclusion of children with disabilities in play.

- Description: This paper describes an innovative cross-institutional learning partnership that was designed to foster the learning of both Pre-Service Teachers (PSTs) and students and teachers from a local regional Secondary College. Around 150 Grade Nine (13-14 year old) students took part in a purpose-designed activity day at the university that was organised and conducted by 34 second year PSTs as part of their teacher education program. This project was designed as an authentic teaching experience for PSTs that would enable them to translate theory from their teacher education course into teaching practice. At the same time the secondary students were offered a range of learning experiences informed by school-derived curriculum. These specifically focused activities contributed to the students’ school based learning programs whilst also encouraging them to think of university as a future option. In this paper reflections, utilizing a self-study methodology, are provided by the lecturers who developed and implemented the program. The lecturers describe and discuss what they observed about the learning of the PSTs. Many of the PSTs indicated strongly that they were able to engage in a scaffolded, authentic teaching experience as preparation for their initial school placements. Overall, the evidence suggests that the initiative offered a powerful learning experience that enabled PSTs to connect theory with teaching practice.

- Description: This paper will examine Pre-Service Teachers’ (PSTs) perspectives on their learning through their involvement in one of three workplace-based initiatives undertaken as part of their teacher education program. Research conducted by Darling-Hammond and colleagues (2008) confirms that highly effective teachers support meaningful learning in a number of ways, including ‘creating ambitious and meaningful tasks’ that reflect how knowledge is used in the field, by engaging students in active learning and by encouraging the type of thinking that enables students to learn to evaluate and guide their own learning (p. 5). The three school-based initiatives selected for this research project have been designed accordingly in an attempt to promote meaningful learning for PSTs. The initiatives that are examined are The Youth Festival, undertaken as part of the Graduate Diploma of Education Secondary (GDE Sec); Pathways to the Adult World (PAW); and, several Small Group Learning Projects in the Bachelor of Education (Physical Education). The study has been conducted as a University of Ballarat Institute of Professional and Organisational Learning (IPOL) teaching and learning fellowship. While the researchers employed a qualitative, self-study methodology in the research, this paper focuses on the PSTs self-study on their learning through their involvement in the various initiatives. Data were derived from an assessment task that was completed by the PSTs after their involvement in one of the work-place based initiatives and subjected to thematic analysis by the researchers. The research attempts to interrogate and reveal what students say that they are learning through their authentic experience in a professional education setting as part of their teacher education coursework.

Amass of data across all stages, from disease diagnosis to palliative care, is further indication of the opportunities and challenges created for effective data management, analysis, prediction and optimization techniques as parts of knowledge management in clinical environments. A Data-driven Decision Guidance Management System (DD-DGMS) architecture can encompass solutions into a single closed-loop integrated platform to empower clinical scientists to seamlessly explore a multivariate data space in search of novel patterns and correlations to inform their research and practice. The paper describes the components of such an architecture, which includes a robust data warehouse as an infrastructure for comprehensive clinical knowledge management.

Given the heterogeneous nature of clinical contexts and corresponding data, the dimensional data model presents itself as an adaptive model that facilitates knowledge discovery, distribution and application, which is essential for clinical decision support. The paper reports on a trial of the DD-DGMS system prototype conducted on diabetes screening data which further establishes the relevance of the proposed architecture to a clinical context.

- Description: In this paper we consider the aspect of teacher education which takes place, not in the school, but in the university classroom. Teaching about teaching, it is argued, must be grounded in students' understanding of the present, but must foster both hope and critique. Beginning from Maxine Greene's (2000) concept of imagination, this paper develops a notion of critical imagination as a way of conceptualizing a critical pedagogy in the university classroom. Two pedagogical strategies based on critical imagination are outlined and analyzed. Writing is prioritized as a pedagogical tool. Excerpts from our professional teaching journals, together with samples of students' writing in response to these strategies, clothe the strategies in the reality of teaching practice. We argue that the use of teaching strategies based on critical imagination as a means of 'jarring' students to think differently seems to move our students to think a little more humanely and a little more critically. But this is neither a simple nor unproblematic task.

- Description: Innovation, both technological and organisational, has become the top national priority in generating strong industrial development in order to stimulate economic development and strengthen competitiveness. From this perspective, it is crucial to identify how various aspects of business management in practice are responding to the challenge of supporting innovation. One crucial aspect under scrutiny lately has been the role of human resource management (HRM) in effectively building the capacity of organisations to innovate through motivation and learning. Recent research has found a positive relationship among HRM policies, innovation and industrial performance. This important relationship has been often mentioned, but without any clear theoretical framework or empirical evidence to identify the type of HRM strategies that support innovation. The aim of this paper is to examine the Australian situation with regard to HRM strategies and their support (or lack thereof) for innovation during the 2000s boom years prior to the recent “Great Recession”. This is done by comparing two distinct HRM systems and strategies implemented in Australia. One is centred around deregulation, the other is centred around regulation. A theoretical framework is developed based on the capability of firms to innovate and how it is strictly related to their ability to substitute between labour inputs, within these two strategies. This framework then provides the basis for examining HRM practices and industrial relations systems in order to identify the difference between the learning practices that are common to successful innovation, and the ones that hamper innovation. The focus of the paper is on the input of innovative individuals. For it is individuals who learn within a frame of reference created by their education and by their social and organisational systems of rewards. The paper will show how through HRM strategies, the process of learning can lead to innovation, but it can also hinder innovation. It is crucial that societies invest in practices that foster and maintain the individual’s motivation to innovate and ability to generate new knowledge.

- Description: Innovation in Australia has become the top national priority in strengthening competitiveness of firms and generating strong economic development. This paper investigates the building of workforce innovation capacity through human resource management (HRM) practices to foster innovation in Australia. Two HRM strategies are identified as having operated in Australia over 40 years. One is a ‘soft’ HRM strategy based on greater worker autonomy; a strategy which dominated in the 1970s and 1980s. The other is a ‘hard’ HRM strategy based on routine worker performance measurement which has increasingly become more relevant since the 1990s and into the 21st Century as the basis for stronger competitive advantage. A dynamic discrete choice model is developed to provide a method for capturing and explaining variations in the relationship between the two strategies and innovation. This approach reframes the economics of innovation using a unique ‘containment of structure and contingency of agency’ spectrum to explain innovation-successful HRM practices which can account for both internal firm management policies and external-to-the-firm effects of government economic policies. For this reason, this study provides a historical understanding that links effective HRM strategy to building innovation capacity from both firm and government levels. Such experience can assist building a stronger Australian Innovation System so often demanded.

- Description: Video coding techniques utilising background frames, provide better rate distortion performance by exploiting coding efficiency in uncovered background areas compared to the latest video coding standard. Parametric approaches such as the mixture of Gaussian (MoG) based background modeling has been widely used however they require prior knowledge about the test videos for parameter estimation. Recently introduced non-parametric (NP) based background modeling techniques successfully improved video coding performance through a HEVC integrated coding scheme. The inherent nature of the NP technique naturally exhibits superior performance in dynamic background scenarios compared to the MoG based technique without a priori knowledge of video data distribution. Although NP based coding schemes showed promising coding performances, they suffer from a number of key challenges - (a) determination of the optimal subset of training frames for generating a suitable background that can be used as a reference frame during coding, (b) incorporating dynamic changes in the background effectively after the initial background frame is generated, (c) managing frequent scene change leading to performance degradation, and (d) optimizing coding quality ratio between an I-frame and other frames under bit rate constraints. In this study we develop a new scene adaptive coding scheme using the NP based technique, capable of solving the current challenges by incorporating a new continuously updating background generation process. Extensive experimental results are also provided to validate the effectiveness of the new scheme.

- Description: Video coding techniques utilising background frames, provide better rate distortion performance by exploiting coding efficiency in uncovered background areas compared to the latest video coding standard. Parametric approaches such as the mixture of Gaussian (MoG) based background modeling has been widely used however they require prior knowledge about the test videos for parameter estimation. Recently introduced non-parametric (NP) based background modeling techniques successfully improved video coding performance through a HEVC integrated coding scheme. The inherent nature of the NP technique naturally exhibits superior performance in dynamic background scenarios compared to the MoG based technique without a priori knowledge of video data distribution. Although NP based coding schemes showed promising coding performances, they suffer from a number of key challenges - (a) determination of the optimal subset of training frames for generating a suitable background that can be used as a reference frame during coding, (b) incorporating dynamic changes in the background effectively after the initial background frame is generated, (c) managing frequent scene change leading to performance degradation, and (d) optimizing coding quality ratio between an I-frame and other frames under bit rate constraints. In this study we develop a new scene adaptive coding scheme using the NP based technique, capable of solving the current challenges by incorporating a new continuously updating background generation process. Extensive experimental results are also provided to validate the effectiveness of the new scheme.

- Description: In cloud environments, IT solutions are delivered to users via shared infrastructure. One consequence of this model is that large cloud data centres consume large amounts of energy and produce significant carbon footprints. A key objective of cloud providers is thus to develop resource provisioning and management solutions at minimum energy consumption while still guaranteeing Service Level Agreements (SLAs). However, a thorough understanding of both system performance and energy consumption patterns in complex cloud systems is imperative to achieve a balance of energy efficiency and acceptable performance. In this paper, we present StressCloud, a performance and energy consumption analysis tool for cloud systems. StressCloud can automatically generate load tests and profile system performance and energy consumption data. Using StressCloud, we have conducted extensive experiments to profile and analyse system performance and energy consumption with different types and mixes of runtime tasks. We collected fine-grained energy consumption and performance data with different resource allocation strategies, system configurations and workloads. The experimental results show the correlation coefficients of energy consumption, system resource allocation strategies and workload, as well as the performance of the cloud applications. Our results can be used to guide the design and deployment of cloud applications to balance energy and performance requirements.

- Description: In contrast with the condition that the trajectory dataset of floating cars (taxis) can be easily obtained from the Internet, it is hard to get the trajectory data of social vehicles (private vehicles) because of personal privacy and government policies. This paper absorbs the idea of game theory, considers the influence of individuals in the group, and proposes a decision behavior based dataset generation (DBDG) model of vehicles to predict future inter-regional traffic. In addition, we adopt simulation tools and generative adversarial networks to train the trajectory prediction model so that the private vehicle trajectory dataset conforming to social rules (e.g., collisionless) is generated. Finally, we construct from macroscopic and microscopic perspectives to verify dataset generation methods proposed in this paper. The results show that the generated data not only has high accuracy and is valuable but can provide strong data support for the Internet of Vehicles and transportation research work. © 2021, Springer Nature Switzerland AG.

- Description: With the explosive growth of new graduates with research degrees every year, unprecedented challenges arise for early-career researchers to find a job at a suitable institution. This study aims to understand the behavior of academic job transition and hence recommend suitable institutions for PhD graduates. Specifically, we design a deep learning model to predict the career move of early-career researchers and provide suggestions. The design is built on top of scholarly/academic networks, which contains abundant information about scientific collaboration among scholars and institutions. We construct a heterogeneous scholarly network to facilitate the exploring of the behavior of career moves and the recommendation of institutions for scholars. We devise an unsupervised learning model called HAI (Heterogeneous graph Attention InfoMax) which aggregates attention mechanism and mutual information for institution recommendation. Moreover, we propose scholar attention and meta-path attention to discover the hidden relationships between several meta-paths. With these mechanisms, HAI provides ordered recommendations with explainability. We evaluate HAI upon a real-world dataset against baseline methods. Experimental results verify the effectiveness and efficiency of our approach. © 2021 ACM.

- Description: Evaluation of visual quality is essentially a multi-dimensional and multi-sensory experience of landscape assessment. Visual quality refers to the character, condition and quality of lakes/wetlands. It involves perceiving, preferring and valuing the visual quality by the public. Visual quality is an outcome of the perceptual, cognitive and emotional processes in response to visual stimuli of a lake environment. Visual quality therefore is dependent upon the perceptual and structural aspects of perceived scenes of wetlands. Visual assessment, an evaluating process of gaining non-material or intangible benefits by people from ecosystems, through spiritual enrichment, cognitive development, self-reflection, recreation, and aesthetic experiences, has now become one of significant research areas under cultural components of ecosystem services. Public perception in such studies is composed from both the objective and subjective elements of human–landscape interactions. However, it is still a matter of debate whether subjective–objective realities are dichotomous or supplementary to enhancing the quality of human experiences in natural settings. In fact, much research considers them as inseparable and integral parts of landscape perception, despite the tendency for disintegrating landscapes into their constituent components. There is a fundamental theoretical divergence of opinions over the question whether a landscape has an intrinsic or ‘objective’ beauty, which may be in some ways measurable or comparable, or whether beauty is a value that can be only attributed subjectively to an area or a specific landscape.
