A narrative interpretative research methodology was used to investigate collaboration between higher education students and an art educator with the aim of establishing a community of learners. Located, Cloud based and graphically built 3D virtual, socially networked, e-learning environments were used to encourage synchronous and asynchronous student participation in authentic learning and collaborative art practice. Discussion focuses on art educator observations, student visual journal entries, their virtual exhibition of artworks on Deakin Art Education Island in Second Life and student evaluations of the unit Navigating the Visual World. It was concluded that immersion in an e-technology rich blended learning environment resulted in the establishment of an effective e-learning community of art.

In this paper, we present an empirical analysis on transfer learning using the Fuzzy Min–Max (FMM) neural network with an online learning strategy. Three transfer learning benchmark data sets, i.e., 20 Newsgroups, WiFi Time, and Botswana, are used for evaluation. In addition, the data samples are corrupted with white Gaussian noise up to 50 %, in order to assess the robustness of the online FMM network in handling noisy transfer learning tasks. The results are analyzed and compared with those from other methods. The outcomes indicate that the online FMM network is effective for undertaking transfer learning tasks in noisy environments.

 In 2007, a young woman, Annabel Catt, died after consuming a capsule sold as “ecstasy” that contained para-methoxyamphetamine. In this paper, we describe how this death was depicted in online drug-user communities and illustrate how the meanings of drug use are negotiated in online settings. News articles, public online discussions, and online fieldwork formed the data. This paper demonstrates how dominant drug discourses may be resisted by drug users, drawing on theories of health resistance and Kane Race’s concept of counterpublic health. Online environments may offer ways of engaging people who use drugs that acknowledge both pleasure and safety. The study’s limitations are noted.

Restraining the spread of rumors in online social networks (OSNs) has long been an important but difficult problem to be addressed. Currently, there are mainly two types of methods 1) blocking rumors at the most influential users or community bridges, or 2) spreading truths to clarify the rumors. Each method claims the better performance among all the others according to their own considerations and environments. However, there must be one standing out of the rest. In this paper, we focus on this part of work. The difficulty is that there does not exist a universal standard to evaluate them. In order to address this problem, we carry out a series of empirical and theoretical analysis on the basis of the introduced mathematical model. Based on this mathematical platform, each method will be evaluated by using real OSN data.We have done three types of analysis in this work. First, we compare all the measures of locating important users. The results suggest that the degree and betweenness measures outperform all the others in the Facebook network. Second, we analyze the method of the truth clarification method, and find that this method has a long-term performance while the degree measure performs well only in the early stage. Third, in order to leverage these two methods, we further explore the strategy of different methods working together and their equivalence. Given a fixed budget in the real world, our analysis provides a potential solution to find out a better strategy by integrating both types of methods together. From both the academic and technical perspective, the work in this paper is an important step towards the most practical and optimal strategies of restraining rumors in OSNs.

BACKGROUND: Increasing participation in transportation cycling represents a useful strategy for increasing children's physical activity levels. Knowledge on how to design environments to encourage adoption and maintenance of transportation cycling is limited and relies mainly on observational studies. The current study experimentally investigates the relative importance of micro-scale environmental factors for children's transportation cycling, as these micro-scale factors are easier to change within an existing neighborhood compared to macro-scale environmental factors (i.e. connectivity, land-use mix, …). METHODS: Researchers recruited children and their parents (n = 1232) via 45 randomly selected schools across Flanders and completed an online questionnaire which consisted of 1) demographic questions; and 2) a choice-based conjoint (CBC) task. During this task, participants chose between two photographs which we had experimentally manipulated in seven micro-scale environmental factors: type of cycle path; evenness of cycle path; traffic speed; traffic density; presence of speed bumps; environmental maintenance; and vegetation. Participants indicated which route they preferred to (let their child) cycle along. To find the relative importance of these micro-scale environmental factors, we conducted Hierarchical Bayes analyses. RESULTS: Type of cycle path emerged as the most important factor by far among both children and their parents, followed by traffic density and maintenance, and evenness of the cycle path among children. Among parents, speed limits and maintenance emerged as second most important, followed by evenness of the cycle path, and traffic density. CONCLUSION: Findings indicate that improvements in micro-scale environmental factors might be effective for increasing children's transportation cycling, since they increase the perceived supportiveness of the physical environment for transportation cycling. Investments in creating a clearly designated space for the young cyclist, separated from motorized traffic, appears to be the most effective way to increase perceived supportiveness. Future research should confirm our laboratory findings with experimental on-site research.

Aim: The need for dietetic students to develop interprofessional collaborative practice capabilities is well recognised. The aim of this study was to examine the ability of an online interprofessional education (IPE) unit (using asynchronous and synchronous media) to improve dietetic students' confidence in understanding professional roles and attitudes associated with interprofessional practice along with exploring their experience in the unit. Methods: Final year master of dietetic students undertaking a compulsory online unit in IPE were invited to complete a questionnaire examining their confidence in understanding professional roles and their interprofessional attitudes both pre- and post-delivery of the unit, and to participate in semi-structured telephone interviews to explore their experience in the unit. Results: Thirty-five dietetic students completed the questionnaire pre- and post-unit, along with seven students undertaking a telephone interview. Their confidence in understanding the roles of other health professions (P = 0.000 to 0.014), self-assessment of interprofessional communication and teamwork skills (P = 0.002) and attitudes towards interprofessional interaction (P = 0.001) and interprofessional relationships (P = 0.002) increased significantly from pre- to post-unit. The students articulated positives about the experience (flexibility of the delivery, opportunity to reflect on personal factors related to teamwork, increasing their knowledge of other professions) and some challenges (lack of body language, some technological difficulties, the need for regular contribution to the teams' asynchronous discussion boards). Conclusions: This study suggests that although there can be some challenges in online IPE, it can be a positive experience and can improve dietetic students' collaborative practice attitudes and confidence in understanding other professional roles.

BACKGROUND OR CONTEXT: A developing international engineering industry is dependent on competition and innovation, creating a market for highly skilled graduates from respected overseas and Australian Engineering universities. The delivery of engineering teaching and learning via blended faceto-face, problem based, research focused and online collaborative learning will continue to be the foundation of future engineering education, however, it will be those institutions who can reshape its learning spaces within a culture of innovation using 1:1 devices that will continue to attract the brightest minds. Investing in educational research that explores the preferred learning styles of learners and matching this to specifically designed 1:1 personalized web applications may be the ‘value add’ to improve student engagement. In this paper, a survey of Australian engineering education is presented and contrasted against a backdrop of internationally recognised educational pedagogy to demonstrate how engineering teaching and learning has changed over time. This paper draws on research and identifies a gap where a necessity to question the validity of 1:1 devices as the next step in the evolution of engineering education needs to be undertaken. How will teaching and learning look using 1:1 devices and will it drive student demand into engineering higher
education courses. Will this lead to improving professional standards within a dynamic engineering education context? How will current and future teaching and learning be influenced by constructivism using 1:1 device technologies? How will the engineering industry benefit from higher education investment in individualised engineering education
using 1:1 devices for teaching and learning?
PURPOSE OR GOAL: To review the current academic thinking around the topic of 1:1 devices within higher education engineering teaching and learning context in Australia. To identify any gaps in the current understandings and use of 1:1 devices within engineering courses in Australia. To generate discussion and better understanding about how the use of 1:1 devices may hinder and/or improve teaching and learning and student engagement.
APPROACH: A review covering the development of engineering education in Australia and a broader international review of engineering teaching methodology. To identify the extent of research into the use and effectiveness of online strategies within engineering education utilising 1:1 devices for teaching and learning. i.e. “Students must feel that they are part of a learning community and derive motivation to engage in the study material from the lecturer.’ (Lloyd et al., 2001) It is proposed to add to the current body of understandings and explore the effectiveness of a constructiveness teaching approach using course material specifically designed to cater for individual learning styles and delivered via the use of 1:1 devices in the classroom. It is anticipated the research will contrast current engineering teaching and learning practices and identify factors that will facilitate a greater understanding about student connectedness and engagement with the teaching and learning experience; where a constructiveness environment is supported with the use of 1:1 devices. Also, it is anticipated that the constructed learning environment will foster a culture of innovation and students will be empowered to take control of their own learning and be encouraged to contribute back to the discussion initiated by the lecture and/or course material with the aid of 1:1 device technologies. A gap has been identified in the academic literature that show there is a need to understand the relationship between engineering teaching, learning, students engagement and the use of 1:1 devices.

ANTICIPATED OUTCOMES: It is anticipated the research will contrast current engineering teaching and learning practices and identify factors that will facilitate a greater understanding about student connectedness and engagement with the teaching and learning experience; where a constructiveness environment is supported with the use of 1:1 devices. Also, it is anticipated that the constructed learning environment will foster a culture of innovation and students will be empowered to take control of their own learning and be encouraged to contribute back to the discussion initiated by the lecture and/or course material with the aid of 1:1 device technologies. A gap has been identified in the academic literature that show there is a need to understand the relationship between engineering teaching, learning, students engagement and the use of 1:1 devices.
RECOMMENDATIONS/IMPLICATIONS/CONCLUSION: A gap exists in the current research about the effectiveness and use of 1:1 devices in engineering education; therefore, it is necessary to undertake further research in the area. It is proposed to hypothesize and conduct field research to identify any shortcomings and possible benefits for engineering educators and learners within a constructivist-teaching
context that explores the relationship between the use of personalized 1:1 devices for teaching and learning, adapting for individual learning styles, and identification and application of appropriate teaching and learning strategies within a constructiveness engineering course approach. Research is required to clarify the following research questions;
• What education teaching and learning strategies best facilitate the use of 1:1 devices for online teaching and learning?
• Does student engagement improve when 1:1 device technologies are used and adapted to cater for individual learning styles during online delivery of engineering courses?
• What are the factors within a university engineering faculty that may hinder and/or support the use of 1:1 devices for online teaching and learning?
• To what extent do 1:1 devices assist engineering educators and students to foster a culture of innovation? The study results will offer engineering educators and students an opportunity to reflect on
their current teaching and learning practice, and contextualise the use of 1:1 devices as a tool to improve student engagement. It is expected the learning benefits will outweigh the implementation costs and derive a unique learning experience that will empower engineering educators and students to inspire a culture of innovation.

Distance education has developed in the past 25 years or so as a way of supplying education to people who would not have access to local college education facilities. This includes students who live in remote regions, students who lack mobility, and students with full-time jobs. More recently this has been renamed to "online learning". Deakin University in Australia has been teaching freshman engineering physics simultaneously to on-campus and online students since the late1990's. The course is part of an online Bachelor of Engineering major that is accredited by the Institution of Engineers Australia.* In this way Deakin answers the call to provide engineering education "anywhere, anytime."**The course has developed and improved with the available educational technology. Starting with printed study guides, a textbook, CD-ROMS, and snail-mail, and telephone/email correspondence with students, the course has seen the rise of websites, online course notes, discussion boards, streamed video lectures, web-conferencing classes and lab sessions, and online submission of student work. Most recently the on-campus version of the course has shifted from a traditional lecture/tutorial/lab format to a flipped-classroom format. The use of lectures has been reduced while the use of tutorials and practical exercises has increased. Primary learning is now accomplished by watching videos prepared by the lecturer and studying the textbook.Offering this course for several years by distance education made this process considerably easier. Most of the educational "infrastructure" was already in place, and the course's delivery to a non-classroom cohort was already established. Thus many elements of the new structure did not have to be produced from scratch. Improvements to the course website and all the course material has benefited all students, both online and on-campus.The new course structure was delivered for the first time in 2014, has run for two semesters, and will continue in 2015. Student learning and performance is being measured by assignment and exam marks for both on-campus and off-campus students. Students are also surveyed to gauge how well they received the new innovations, especially the video presentations on the lab experiments. It was found that student performance in the new structure was no worse than that in the older structure (average on-campus grades increased 10%), and students in general welcomed the changes. Similar transitions are being implemented in other courses in Deakin's engineering degree program.This presentation will show how physics is taught to online students, outline the changes made to support flipping the on-campus classroom, and how that process benefited the off-campus cohort.

Introduction and Aims The aim of this study was to determine changes in advertising expenditures across eight media channels for the four main alcohol beverage types and alcohol retailers in Australia. Design and Methods Yearly advertising expenditures between January 1997 and December 2011 obtained from a leading media-monitoring company. Media channels assessed were: free-to-air television, newspapers, magazines, radio, outdoors (billboards), cinema, direct mail (from 2005) and online (from 2008). Data were categorised into alcohol retailers (e.g. supermarkets, off-licences) or four alcoholic beverage types (beer, wine, spirits, premixed spirits/cider). Regression analyses examined associations between year and expenditure. Results Total alcohol advertising expenditure peaked in 2007, then declined to 2011 (P = 0.02). Television advertising expenditure declined between 2000 and 2011 (P < 0.001), while outdoor advertising expenditure increased between 1997 and 2007. Alcohol retailers' advertising expenditure increased over time (P < 0.001), and from the mid-2000s exceeded expenditure for any single beverage category. For both beer and spirits, television advertising expenditure declined over time (beer: P < 0.001; spirits: P < 0.001) while outdoor advertising expenditure increased (beer: P < 0.001; spirits: P = 0.02). However, the number of advertised beer (P < 0.001), spirits (P < 0.001) and wine (P = 0.01) products increased over time. Discussion and Conclusions Retailers are playing an increasing role in advertising alcohol. As our study excluded non-traditional advertising media (e.g. sponsorships, in-store) we cannot determine whether declines in television advertising have been offset by increases in advertising in newer media channels. However, our findings that media channels used for alcohol advertising have changed over time highlights the need for adequate controls on alcohol advertising in all media channels.

Overweight and obesity are one of the most salient issues within society today, and the stigmatisation of overweight individuals is prevalent and widespread. Utilising interviews with 44 individuals who blog within an online fat acceptance community known as the Fatosphere, participants' perceptions of inclusion and exclusion were examined within their offline and online environments. Additionally, the effect this had on their offline lives was examined. Participants described a profound sense of exclusion within their offline lives through three agencies: the medicalisation of 'fatness', the weight loss industry and the media, which echoed descriptions of moral judgement. Furthermore, a sense of inclusion was described within the Fatosphere through the protection and support that they found within this 'safe space'. The effects of the Fatosphere influenced their lives in both negative and positive ways, allowing them to better deal with stigma and discrimination, but sometimes effecting their offline relationships in a negative manner. The Fatosphere provides a unique opportunity for corpulent individuals to engage in a community that is removed from the prominent weight-related discourse within modern society.

Abstract:-Global language and cultural communicative competency is an ever increasing requirement in our connected world. Learners of Arabic at the only five Australian universities where Arabic is taught have access to predominantly on-campus delivery modes. One of the main challenges learners face when learning another language (L2) in an academic setting in countries where that language is not actively used – so little L2 exposure – is that it is harder to provide meaningful contexts for learning. This restriction in L2 exposure in the formal academic framework is due to the limited face-to-face learning time and, more significantly, is compounded by lack of exposure to the language‟s authentic use settings. Students are often isolated from the target language‟s authentic discourse communities and native speakers. This situation is exacerbated for Cloud (online) students, studying in relative isolation. All of these factors make developing communicative oral fluency in Modern Standard Arabic (MSA) moredifficult and challenging for many learners. This paper will discuss two innovative approaches used at Deakin University in Melbourne, Australia to enable learners of Arabic at Deakin University to practice their developing skills by listening, practising, and experiencing directly how the language is used outside the classroom boundaries as well as allow learners to develop their oral and cultural communicative competency by engaging them in simulating and evolving authentic language scenarios with native Arabic speakers through the Virtual World (VW).
