This paper reports on part of a teacher/researcher’s PhD action research study. It explains the complexity of features that social media brings to the teaching and learning process while discussing the simplicity and power of its use. Through the action research cycle, learning programs were designed to take advantage of the unique communicative methods offered by social media and web 2.0 whilst maintaining the value of face-to-face learning. Students used social media spaces such as blogs, groups and discussion forums as well as developing their own profiles and avatars to communicate online by making friends, leaving comments and uploading content which included publishing, peer reviewing and self assessment. The author argues that, by designing learning that valued and combined the attributes of social media, Web 2.0 and face-to-face teaching she was able to produce a more student-centred approach; hence, developing a ‘Hybrid’ learning environment which supported many 21st Century skills.

This article reports on part of the author’s PhD action research study. It examines the complexity of features that social media and Web 2.0 offer when combined with face-to-face teaching and learning. Action research was used to help redesign the learning programs of thirteen Middle Years classes over an eighteen month period. These learning programs took advantage of the unique communicative methods offered by social media and provided spaces such as blogs, groups and discussion forums. Students developed their own identity when working online, made online friends, left comments for peers and uploaded content which included publishing, peer reviewing and self assessment. The research highlighted the simplicity in the creation and exchange of user-generated content and interaction while identifying a complex depth behind such interaction. Designing learning programs using social media enabled the students to be active and valued participants in the learning process and a ‘hybrid’ learning environment

This paper discusses how course design may draw upon social media in order to teach students appropriate skills for a network society in the context of team-work based learning. The emphasis is not upon web 2.0 and social media as inherently suited to providing educational solutions, but upon the ways in which they can be adapted by course designers within the framework of explicit learning objectives. More specifically, we provide a case study of how the use of social media in a blended or wholly-online learning environment provides affordances for team-based collaborative learning, especially when incorporated within a course design that encourages independent, self-directed and authentic learning. This paper argues we need to assess the social aspects of social media, rather than upon the technological, that is, avoid the fetishisation of 'apps,' through the creation of assessment that alternately foregrounds a critical appraisal of web 2.0 technologies and places onus upon the students to develop, with guidance, teamwork skills and processes. We provide an example of how it is possible to integrate web 2.0 technologies into their learning processes and assessment, in order to teach about the realities of collaborating with others in small teams in a work environment increasingly mediated by the Internet. In order to achieve these learning outcomes, course design needs to balance scaffolding with the need to place the imperative for learning specific content and skills upon the students, the latter through the provision of assessment outcomes and resources that the students need to work towards together.

This paper presents an integration of a novel document vector representation technique and a novel Growing Self Organizing Process. In this new approach, documents are represented as a low dimensional vector, which is composed of the indices and weights derived from the keywords of the document.

An index based similarity calculation method is employed on this low dimensional feature space and the growing self organizing process is modified to comply with the new feature representation model.

The initial experiments show that this novel integration outperforms the state-of-the-art Self Organizing Map based techniques of text clustering in terms of its efficiency while preserving the same accuracy level.

Here we report a viable route to fibrillar micelles and entrapped vesicles in aqueous solutions. Nanofibrillar micelles and entrapped vesicles were prepared from complexes of a biodegradable block copolymer poly(ethylene oxide)-block-poly(lactide) (PEO-b-PLA) and a polyelectrolyte poly(acrylic acid) (PAA) in aqueous media and directly visualized using cryogenic transmission electron microscopy (cryo-TEM). The self-assembly and the morphological changes in the complexes were induced by the addition of PAA/water solution into the PEO-b-PLA in tetrahydrofuran followed by dialysis against water. A variety of morphologies including spherical wormlike and fibrillar micelles, and both unilamellar and entrapped vesicles, were observed, depending on the composition, complementary binding sites of PAA and PEO, and the change in the interfacial energy. Increasing the water content in each [AA]/[EO] ratio led to a morphological transition from spheres to vesicles, displaying both the composition- and dilution-dependent micellar-to-vesicular morphological transitions.

his study investigates the dynamic interplay between news media and the Northern Territory’s policy of bilingual education for indigenous children living in some remote communities. It provides evidence to support the argument that the media-related practices of a range of policy actors resulted in policy processes being shaped to a significant degree by ‘media logic’. The research is based on depth interviews and uses the spoken words of participants to gain access to the local experiences and perspectives of those invested in developing, influencing and communicating the bilingual education policy. Through the analysis of more than 20 interviews with journalists, public servants, academics, and politicians as well as indigenous and non-indigenous bilingual education advocates, I have identified a range of media-related practices that have enabled policy actors to penetrate the policy debate, define problems for policymaking and public discussion through the news media, and thereby exert particular forms of influence in the policy process. The study also provides a ‘southern theory’ analysis of the Yolngu public sphere and a Bourdesian understanding of the journalism sub-field of indigenous reporting in the Northern Territory. It shows that issues of physical and cultural remoteness and the need for journalists to develop cultural competence are the hallmarks of this reporting specialization. It also identifies marked differences in journalists’ relationships with government, academic and indigenous sources and how these differences play out in the way participants understand the production and reception of media texts. This research makes an innovative contribution to Australian Journalism Studies by demonstrating how indigenous epistemologies and knowledges offer fresh perspectives and insights about news media and indigeneity that can be brought into balance with northern theories to build what Connell (2007) has called ‘southern theory’. This dovetails with another key outcome, which is the development of an academic form of journalism that serves indigenous peoples’ self-determinist aims for scholarly research, based in indigenous perspectives and research methodologies.

Gail used social and participatory media in the secondary school classroom, not just to engage students but also to enhance their learning. Her action research successfully used concepts of formal and informal learning as well as peer review and peer/self-assessment. For the teacher, unlearning many previous practices became essential.

The focus of this research was to explore how social and participatory media could be used to enhance the face-to-face teaching and learning process. Action research was used to design learning that valued the students’ own experiences and to encourage students to create, connect and form a partnership in the learning process: hence supporting students' strengths and abilities. To monitor and participate in the use of social media required an increase in the teacher's work time. As a partial counter-balance, it was found that the teacher/researcher successfully reduced her time spent on correction by implementing peer and self-assessment and by making more effective use of classroom observations. This led to a valuable triangulation of assessment data. Reviewing many of the screen clips collected in this study, one can see the diversity of roles and activities in which the students were engaged, and their development over time through the action research cycle. Combining Web 2.0, face-to-face teaching and social media, where students made online friends and used pseudonyms, provided students with more choices and flexibility when working, communicating and learning. This research may help curriculum developers interweave new technologies, new literacies and multimodal learning methods into day-to-day learning programs. The developed methods of learning and designs should also be transferable to other educational learning environments.

Rural/regional news is emerging as a vital area of media policy and research throughout the world as industry bodies, governments and academics grapple with debates concerning the future of news in a complex digital world. However, there has been little examination of media plurality at the rural/regional level, or research into the sustainability of the sector in Australia. Such concerns go to questions of what roles industry and government might play in ensuring its future. The Finkelstein report in 2012 noted that many rural/regional newspapers in Australia had limited resources and consequently low capacity for in-depth coverage of local issues. In the meantime, the funding model of the Australian Broadcasting Corporation (which services rural/regional areas as part of its charter) has come under intense scrutiny by the federal Liberal-National Party coalition government. Signs from abroad – especially from the United Kingdom – are troubling. Several independent inquiries have called for policy initiatives to address what British scholars describe as the growing “democratic deficit” created by the closure of hundreds of local UK newspapers since 2004. This paper canvasses current and emerging media policy settings in the UK, the United States and Australia before posing some broader questions on the future of rural/regional news in Australia.

Abstract: Waleed Aly is arguably the most visible and vocal Australian public intellectual from a non-Anglo-Australian background. The ubiquitous Aly is a veritable Renaissance man - he is a television presenter, radio host, academic and rock musician. He is also a former lawyer, and served on the executive committee of the Islamic Council of Victoria. In short, he is the 'go-to' Muslim for commentary on a wide range of political and civic affairs. This article argues that Aly's media profile and celebrity status have as much to do with an Australian cultural imaginary that posits 'whiteness' as an uncontestable normative value as it does with Aly's undoubted skills as a journalist, academic and cultural commentator. It examines Aly's career with reference to Ghassan Hage's concept of 'whiteness' as a form of aspirational cultural capital and various theories of persona and performativity. For Hage, 'whiteness' is not a literal skin colour; rather, it consists of elements that can be adopted by individuals and groups (such as nationally valued looks, accents, tastes, cultural preferences and modes of behaviour). While entry to what Hage calls Australia's 'national aristocracy' is generally predicated on possessing the correct skin tone, it is theoretically possible for dark-skinned people such as Waleed Aly to enter the field of national belonging and partake in public discourse about a range of topical issues. More specifically, the article substantiates its claims about Aly's status as a member of Australia's cultural aristocracy through a comparative discourse and performance analysis of his presentation of 'self' in four distinctive media contexts: Channel 10's The Project, the ABC RN Drive program, ABC TV's Q&A and the SBS comedy-talk show Salaam Caf , which looked at the 'funny side of life as an Australian Muslim' and showcased other multi-talented Muslim professionals of both genders.

Purpose: To review the literature relating to use of social media by people with a traumatic brain injury (TBI), specifically its use for social engagement, information exchange or rehabilitation.

Method: A systematic review with a qualitative meta-synthesis of content themes was conducted. In June 2014, 10 databases were searched for relevant, peer-reviewed research studies in English that related to both TBI and social media.

Results
: Sixteen studies met the inclusion criteria, with Facebook™ and Twitter™ being the most common social media represented in the included studies. Content analysis identified three major categories of meaning in relation to social media and TBI: (1) risks and benefits; (2) barriers and facilitators; and (3) purposes of use of social media. A greater emphasis was evident regarding potential risks and apparent barriers to social media use, with little focus on facilitators of successful use by people with TBI.

Conclusions:
Research to date reveals a range of benefits to the use of social media by people with TBI however there is little empirical research investigating its use. Further research focusing on ways to remove the barriers and increase facilitators for the use of social media by people with TBI is needed. Implications for Rehabilitation: Communication disabilities following traumatic brain injury (TBI) can be wide-ranging in scope and social isolation with loss of friendships after TBI is common. For many people, social media is rapidly becoming a usual part of everyday communication and its use has the potential to increase communication and social participation for people with TBI.There is emerging evidence and commentary regarding the perceived benefits and risks, barriers and facilitators and purposes of use of social media within the TBI population.Risks associated with using social media, and low accessibility of social media sites, form barriers to its use. Facilitators for social media use in people with TBI include training the person with TBI and their communication partners in ways to enjoy and use social media safely.There is minimal rigorous evaluation of social media use by people with TBI and scant information regarding social media use by people with communication disabilities after TBI. Further investigation is needed into the potential benefits of social media use on communication, social participation and social support with the aim of reducing social isolation in people with TBI.

Ageing well and successful ageing have become important themes to describe how older individuals should keep ageing at bay. Products and services aimed at controlling ageing have become associated with ageing well. In this study we aimed to analyse the representation of older women in advertisements specific to appearance and ageing. In particular, we sought to explore how ageing for women was presented in the media over a period 50 years and when advertisements began to use the term 'anti-ageing'. A content analysis of 710 advertisements from two prominent Australian women's magazines, from 1960 to 2010, was conducted. Analyses showed that advertisements provided a narrow range of images representing women's physical appearance. The underlying messages were that ageing is problematic and that it had become unforgivable to show any signs of ageing. Text contained in advertisements for beauty products from the two chosen Australian magazines often gave specific and prescriptive advice to women on ways to avoid losing their youthful appearance. It was concluded that media relay powerful messages to spread and modify cultural beliefs informing individuals of a range of options that propose liberation from the problem of ageing.

Traditionally, the main source of funding for university research comes from either private or government grants. Grant schemes are usually highly competitive with low success rates, favour experienced or senior researchers and take considerable time to be processed thereby delaying potential discoveries. In December 2012 pozible.com and Deakin University agreed to create an opportunity for the community funding of Australian university research. Research My World launched to the public in May 2013 with eight campaigns spanning a range of academic discipline areas and project types. Subsequent project cycles have occurred at approximately six monthly intervals and the program was expanded to include research bids from other universities and research centres. As of mid-November 2015, 19 successful research crowdfunding projects have raised more than more than AU$185,000 in funding at Deakin University alone. This paper presents the results of a research investigation into the Research My World crowdfunding initiative. We detail the method developed for the collection and visualisation of social media data related to the research crowdfunding projects, the analysis of the links between social media activity and project success, and the general guidance for future project cycles that we derived from this analysis.

BACKGROUND: Psychosocial interventions have an important role in promoting recovery in people with persisting psychotic disorders such as schizophrenia. Readily available, digital technology provides a means of developing therapeutic resources for use together by practitioners and mental health service users. As part of the Self-Management and Recovery Technology (SMART) research program, we have developed an online resource providing materials on illness self-management and personal recovery based on the Connectedness-Hope-Identity-Meaning-Empowerment (CHIME) framework. Content is communicated using videos featuring persons with lived experience of psychosis discussing how they have navigated issues in their own recovery. This was developed to be suitable for use on a tablet computer during sessions with a mental health worker to promote discussion about recovery.

METHODS/DESIGN: This is a rater-blinded randomised controlled trial comparing a low intensity recovery intervention of eight one-to-one face-to-face sessions with a mental health worker using the SMART website alongside routine care, versus an eight-session comparison condition, befriending. The recruitment target is 148 participants with a schizophrenia-related disorder or mood disorder with a history of psychosis, recruited from mental health services in Victoria, Australia. Following baseline assessment, participants are randomised to intervention, and complete follow up assessments at 3, 6 and 9 months post-baseline. The primary outcome is personal recovery measured using the Process of Recovery Questionnaire (QPR). Secondary outcomes include positive and negative symptoms assessed with the Positive and Negative Syndrome Scale, subjective experiences of psychosis, emotional symptoms, quality of life and resource use. Mechanisms of change via effects on self-stigma and self-efficacy will be examined.

DISCUSSION: This protocol describes a novel intervention which tests new therapeutic methods including in-session tablet computer use and video-based peer modelling. It also informs a possible low intensity intervention model potentially viable for delivery across the mental health workforce.
