- Description: Students describe the Library as being central to their learning, offering focus and inspiration, enabling access to information and technologies, and collaboration with peers. Deakin University Library’s building redevelopment program has been integral to the Library’s re-imagined value proposition for students learning in the digital age. The introduction of new generation library and learning spaces strengthens the University’s offer to students for a brilliant education where you are and where you want to go through premium cloud and located learning experiences that are personal, engaging and relevant. The Library’s building projects are distinctive in terms of location and the built environment, as well as the characteristics of the university campus communities. Each progressive project has brought new aspirations and challenges. Through joint research with Deakin University’s School of Architecture and Built Environment, the Library has developed a quality framework for planning and assessing library and learning spaces. This paper will discuss the research findings to date on the quality framework and the need to continually review and assess indicators of quality in a highly dynamic digital environment. The Library’s experiences in introducing high-end multimedia provide some insights into planning for and delivering enduring value. The next steps in exploring the question of how library spaces assist students in achieving their learning goals are introduced.

- Description: Activists use digital as well as mainstream media tools to attract supporters, advertise their campaigns, and raise awareness of issues in the broader community. Activism and Digital Culture in Australia examines the use of digital tools and culture by Australian and international activist organisations to facilitate public engagement, participation and deliberation in issues and advance social change. In particular the book engages media studies, cultural studies, social theory and various ethical and political philosophical perspectives to examine the use of digital multi-platform tools by activist organisations and advocates for social change to a) disseminate information and raise public awareness; b) invoke, inform and shape public debate through the provision of information and invocation of affect; and c) garner public support (including funding) for issues and for associated social change. Engaging both qualitative and quantitative approaches, these case studies will demonstrate the richness of digital culture for activism and advocacy, examining the use by activist organisations of such digital media tools as apps, blogging, Facebook, RSS, Twitter, and YouTube. The shows that digital culture offers productive mechanisms and spaces for the reshaping of society itself to take more of a participatory role in progressing social change.

- Description: Negative stereotyping of alternative diets such as veganism and other plant-based diets has been common in Australia, conventionally a meat-eating culture (OECD qtd. in Ting). Indeed, meat consumption in Australia is sanctioned by the ubiquity of advertising linking meat-eating to health, vitality and nation-building, and public challenges to such plant-based diets as veganism. In addition, state, commercial enterprises, and various community groups overtly resist challenges to Australian meat-eating norms and to the intensive animal husbandry practices that underpin it. Hence activists, who may contest not simply this norm but many of the customary industry practices that comprise Australia’s meat production, have been accused of promoting a vegan agenda and even of undermining the “Australian way of life”...

- Description: An Internet of Multimedia Things (IoMT) architecture aims to provide a support for real-time multimedia applications by using wireless multimedia sensor nodes that are deployed for a long-term usage. These nodes are capable of capturing both multimedia and nonmultimedia data, and form a network known as Wireless Multimedia Sensor Network (WMSN). In a WMSN, underlying routing protocols need to provide an acceptable level of Quality of Service (QoS) support for multimedia traffic. In this paper, we propose a Seamless and Authorized Streaming (SAMS) framework for a cluster-based hierarchical WMSN. The SAMS uses authentication at different levels to form secured clusters. The formation of these clusters allows only legitimate nodes to transmit captured data to their Cluster Heads (CHs). Each node senses the environment, stores captured data in its buffer, and waits for its turn to transmit to its CH. This waiting may result in an excessive packet-loss and end-to-end delay for multimedia traffic. To address these issues, a channel allocation approach is proposed for an intercluster communication. In the case of a buffer overflow, a member node in one cluster switches to a neighboring CH provided that the latter has an available channel for allocation. The experimental results show that the SAMS provides an acceptable level of QoS and enhances security of an underlying network.

- Description: The encoding of HD videos faces two challenges: requirements for a strong processing power and a large storage space. One time-efficient solution addressing these challenges is to use a cloud platform and to use a scalable video coding technique to generate multiple video streams with varying bit-rates. Packet-loss is very common during the transmission of these video streams over the Internet and becomes another challenge. One solution to address this challenge is to retransmit lost video packets, but this will create end-to-end delay. Therefore, it would be good if the problem of packet-loss can be dealt with at the user's side. In this paper, we present a novel system that encodes and stores the videos using the Amazon cloud computing platform, and recover lost video frames on user side using a new Error Concealment (EC) technique. To efficiently utilize the computation power of a user's mobile device, the EC is performed based on a multiple-thread and parallel process. The simulation results clearly show that, on average, our proposed EC technique outperforms the traditional Block Matching Algorithm (BMA) and the Frame Copy (FC) techniques.

- Description: •Thematic analysis investigating thoughts prior to social media ‘liking’ and posting.•Egoistic motivations were present in both posting and ‘liking’ behaviours.•Users commonly considered the effect of their content or ‘likes’ on viewers.•‘Liking’ appears to truly indicate enjoyment and appreciation of content.•Numerous considerations point to the importance of these simple online actions. This study aimed to investigate the thoughts that social media users have prior to posting or ‘liking’ images on social media particularly exploring the presence of egoistic, self-presentation considerations. Responses to two open-ended questions regarding considerations prior to posting (n = 203) and ‘liking’ (n = 195) images on social media were analysed using thematic analysis. Egoistic motivations influenced both posting and ‘liking’ an image on social media suggesting an awareness that self-presentation can be affected (and therefore manipulated) through image posting and ‘liking’. Users also considered who would see their content or behaviour, and the effect this might have on others. Finally, ‘liking’ actually represents liking, with enjoyment and image value considered prior to providing public, online appreciation.

- Description: •First to use Theory of Planned Behaviour (TPB) to predict ‘selfie’ editing.•TPB model extended through control variables and the inclusion of Narcissism.•Prior editing and Facebook Intensity significantly predicted editing intentions.•Attitudes and subjective norms, but not PBC, significantly contributed to the model.•Narcissism explained a small, significant proportion of intentions beyond the TPB. Little research has examined image-editing behaviour on social media, yet with images being a key form of online social communication, the importance of such research is evident. The aim of the current study was to examine the factors that influence peoples’ intentions to post digitally altered self-images on the Facebook platform, using an extended Theory of Planned Behaviour (TPB) model. It was hypothesised that after controlling for age, prior editing application use, and integration of Facebook in a user’s life, the TPB variables (attitudes, subjective norms, and perceived behavioural control [PBC]) would explain a significant proportion of intention to post digitally altered images on Facebook. Furthermore, that the addition of narcissism would explain further variation in intentions, beyond that explained by the control and TPB variables. Participants (N = 151 Mage = 25.6 years 76% female) completed an online survey assessing each of the aforementioned variables. Hierarchical multiple regression revealed that each of the hypotheses were supported, with all variables significantly contributing to the prediction of intentions, except PBC and age. This study sheds light on the predictors of image-editing behaviour, and sets the stage for subsequent research examining editing behaviours on Facebook as well as other social media platforms (e.g. Instagram).

- Description: Snapchat is emerging as a popular image-based instant messaging service. Aiming to provide the first insight into the characteristics of Snapchat users, this study (N = 235) drew on the limited existing Snapchat research base, uses and gratifications theory, and other social media research to derive a range of research questions about Snapchat users vs. non-users. As hypothesised, Snapchat users were younger, placed significantly more importance on social connectedness than non-users, reported significantly greater reliance on graphics in communication, were more likely engage with technology regularly, had greater comfort with technological multitasking, and showed a stronger preference for online social interaction than non-users. However, in contrast to predictions, a desire for instantaneous interaction and reward was not significantly associated with Snapchat use. The findings are considered in terms of a proposed research agenda, including relevant theoretical paradigms (such as belongingness, technology acceptance, psycholinguistic, and semiotic theories) and applied outcomes (such as social capital and communication). Frameworks for future Snapchat research are provided. •First investigation of Snapchat user vs. non-user characteristics.•Snapchat users were younger and use graphics, technology, and multitask more often.•Snapchat users place greater importance on social connectedness.•Snapchat users have a stronger preference for online social interaction.•Relevant theory and applications are suggested in terms of a Snapchat research agenda.
