Identifying the Events That Connect Social Media Users : Charting Follower Accession on Twitter

Twitter is the focus of much research attention, both in traditional academic circles and in commercial market and media research, as analytics give increasing insight into the performance of the platform in areas as diverse as political communication, crisis management, television audiencing and other industries. While methods for tracking Twitter keywords and hashtags have developed apace and are well documented, the make-up of the Twitter user base and its evolution over time have been less understood to date. Recent research efforts have taken advantage of functionality provided by Twitter's Application Programming Interface to develop methodologies to extract information that allows us to understand the growth of Twitter, its geographic spread and the processes by which particular Twitter users have attracted followers. From politicians to sporting teams, and from YouTube personalities to reality television stars, this technique enables us to gain an understanding of what prompts users to follow others on Twitter. This article outlines how we came upon this approach, describes the method we adopted to produce accession graphs and discusses their use in Twitter research. It also addresses the wider ethical implications of social network analytics, particularly in the context of a detailed study of the Twitter user base.

Tracking spatio temporal movement of human in terms of space utilization using media access control address data

Using Media-Access-Control (MAC) address for data collection and tracking is a capable and cost effective approach as the traditional ways such as surveys and video surveillance have numerous drawbacks and limitations. Positioning cell-phones by Global System for Mobile communication was considered an attack on people's privacy. MAC addresses just keep a unique log of a WiFi or Bluetooth enabled device for connecting to another device that has not potential privacy infringements. This paper presents the use of MAC address data collection approach for analysis of spatio-temporal dynamics of human in terms of shared space utilization. This paper firstly discuses the critical challenges and key benefits of MAC address data as a tracking technology for monitoring human movement. Here, proximity-based MAC address tracking is postulated as an effective methodology for analysing the complex spatio-temporal dynamics of human movements at shared zones such as lounge and office areas. A case study of university staff lounge area is described in detail and results indicates a significant added value of the methodology for human movement tracking. By analysis of MAC address data in the study area, clear statistics such as staff’s utilisation frequency, utilisation peak periods, and staff time spent is obtained. The analyses also reveal staff’s socialising profiles in terms of group and solo gathering. The paper is concluded with a discussion on why MAC address tracking offers significant advantages for tracking human behaviour in terms of shared space utilisation with respect to other and more prominent technologies, and outlines some of its remaining deficiencies.

The Media and Communications in Australia, [4th Edition]

The most widely used introduction to the Australian media, fully updated to reflect the increasing prominence of the internet in the communication and entertainment industries. Description Traditional media are being reshaped by digital technologies. The funding model for quality journalism has been undermined by the drift of advertising online, demarcations between different forms of media are rapidly fading, and audiences have fragmented. We can catch up with our favourite TV show on a tablet, social media can be more important than mainstream radio in a crisis, and organisations large and small have become publishers in their own right on apps. Nevertheless mainstream media remain powerful. The Media and Communications in Australia offers a systematic introduction to this dynamic field. Fully updated and revised to take account of recent developments, this fourth edition outlines the key media industries and explains how communications technologies are impacting on them. It provides a thorough overview of the main approaches taken in studying the media, and includes an expanded 'issues' section with new chapters on social media, gaming, apps, the environment, media regulation, ethics and privacy. With contributions from some of Australia's best researchers and teachers in the field, The Media and Communications in Australia remains the most comprehensive and reliable introduction to media and communications available. It is an ideal student text, and a reference for teachers of media and anyone interested in this influential industry.

Making media participatory: Digital storytelling

From journalism to social media, the practices of our professional storytellers continue to evolve and change along with our storytelling institutions and their functions. Comprehending these developments is a key problem of contemporary media and cultural studies. Are the politics of representation giving way to a new progressive politics of self-representation and direct participation? Or, instead, are these new genres of self-representation part of a more general demotic turn in the function of contemporary media? Do media merely mediate or amplify cultural identities, or is media functionality becoming, closer to that of a translator or even an author of identities? How can we know if the changing actor-networks of storytelling contribute to a wider democratisation, a reshaping of the hierarchies of voice and agency? This chapter considers the place of one specific critical participatory media production practice known as 'digital storytelling’ in addressing these larger questions of socio-cultural change.

Social media and e-democracy in Fiji, Solomon Islands and Vanuatu

This paper examines the extent social media is enabling e-democracy in Fiji, Solomon Islands and Vanuatu. The study conducts an interpretative case study approach interviewing active social media users, political actors, civil servants, civilians, civil society actors and tertiary students. The study also conducts a content analysis of popular “political social media” Facebook pages in these three countries. The findings of the study suggest that social media is playing a role in facilitating citizen engagement with governments, making governments accountable and providing a means for citizens to be informed, to discuss and share views on political matters. However, social media usage is evolving quite differently in these three countries and factors such as high levels of militarism (Fiji), high levels of corruption (Solomon Islands) and also rapid ICT development (Vanuatu) have contributed towards shaping the potential of social media as a democratic enabler and political tool in these countries.

Co-creative media in remote Indigenous communities

This paper examines co-creative video outputs that have originated from, or relate to, remote Indigenous communities in Australia. Scholarly work on remote media has mostly operated at the interface of media studies and anthropology, seeking to identify how cultural systems shape the production, distribution and reception of media in Aboriginal communities. This paper looks instead at content themes, funding sources and institutions during the 2010-2013 period, and examines the factors that may be determining the quantity of co-creative outputs, as well as the types of stories that get produced. I argue that the focus on culture has obscured important shifts in remote media policy and funding, including a trend towards content designed to address social disadvantage.

Creating regional resilience in Australia

This paper explores the impact that extreme weather events can have on communities. Using the Brisbane floods of 2011 to examine the recovery operations, the paper highlights the effectiveness of recovery and rebuilding in already strong and resilient communities. Our research has shown that communities which have a strong sense of identity, as well as organized places to meet, develop resilient networks that come into play in times of crisis. The increasing trend of the fly-in/fly-out (FIFO) or drive-in/drive-out (DIDO) workforce to service regional areas has undermined the resilience of existing communities. The first hint of this occurs with community groups not knowing who their neighbours are. The paper is based on research examining the needs of groups in regional communities with the goal to better equip regional communities with the capacity to respond positively to change (and crisis) through in-novative, evidence-based policies, resilience strategies and tools. Part of this process was to build an evidence-base to address a range of challenges associated with the place-based environments and the sharing of information systems within communities and decision makers. The first part of the paper explores the context in which communities have been required to mobilize in response to crises; the issues that have galvanized a common purpose; and the methods by which these communities shared their knowledge. The second part of the paper examines how communities could plan for and mitigate natural disasters in the future by developing better decision making tools. The paper defines the requirements for information systems that will link data models of built infrastruc-ture with data from the disaster and response plans. These will then form the basis for the use of social media to coordinate activities between official crews and the public to improve response coordination and provide the technology that could reduce the time required to allow communities to resume some semblance of normality.

Amateur Media : Social, Cultural and Legal Perspectives

The rise of Web 2.0 has pushed the amateur to the forefront of public discourse, public policy and media scholarship. Typically non-salaried, non-specialist and untrained in media production, amateur producers are now seen as key drivers of the creative economy. But how do the activities of citizen journalists, fan fiction writers and bedroom musicians connect with longer traditions of extra-institutional media production? This edited collection provides a much-needed interdisciplinary contextualisation of amateur media before and after Web 2.0. Surveying the institutional, economic and legal construction of the amateur media producer via a series of case studies, it features contributions from experts in the fields of law, economics and media studies based in the UK, Europe and Singapore. Each section of the book contains a detailed case study on a selected topic, followed by two further pieces providing additional analysis and commentary. Using an extraordinary array of case studies and examples, from YouTube to online games, from subtitling communities to reality TV, the book is neither a celebration of amateur production nor a denunciation of the demise of professional media industries. Rather, this book presents a critical dialogue across law and the humanities, exploring the dynamic tensions and interdependencies between amateur and professional creative production. This book will appeal to both academics and students of intellectual property and media law, as well as to scholars and students of economics, media, cultural and internet studies.

Histories of user-generated content : between formal and informal media economies

Debates about user-generated content (UGC) often depend on a contrast with its normative opposite, the professionally produced content that is supported and sustained by commercial media businesses or public organisations. UGC is seen to appear within or in opposition to professional media, often as a disruptive, creative, change-making force. Our suggestion is to position UGC not in opposition to professional or "producer media", or in hybridised forms of subjective combination with it (the so-called "pro-sumer" or "pro-am" system), but in relation to different criteria, namely the formal and informal elements in media industries. In this article, we set out a framework for the comparative and historical analysis of UGC systems and their relations with other formal and informal media activity, illustrated with examples ranging from games to talkback radio. We also consider the policy implications that emerge from a historicised reading of UGC as a recurring dynamic within media industries, rather than a manifestation of consumer agency specific to digital cultures.

Media in a transitioning Nepal : does expansion translate to pluralism?

Characterized by socio-political changes, instability and conflict since 1990, Nepal is a nation in political transition. The media play a significant role in influencing this transition. Since 1990, various global and local factors have contributed to an unprecedented growth in the mass media in Nepal. This article analyses the expansion in the media against indicators of media pluralism to ask whether this expansion, within a difficult political transition, translates to media pluralism. The article draws upon qualitative research to assess the media market, the resources available for the media, diversity in media ownership and products, competition and ethics and policy and regulatory provisions within a struggling economy and an environment of poor law and order.

Antibodies mediate formation of neutrophil extracellular traps in the middle ear and facilitate secondary pneumococcal otitis media

Otitis media (OM) (a middle ear infection) is a common childhood illness that can leave some children with permanent hearing loss. OM can arise following infection with a variety of different pathogens, including a coinfection with influenza A virus (IAV) and Streptococcus pneumoniae (the pneumococcus). We and others have demonstrated that coinfection with IAV facilitates the replication of pneumococci in the middle ear. Specifically, we used a mouse model of OM to show that IAV facilitates the outgrowth of S. pneumoniae in the middle ear by inducing middle ear inflammation. Here, we seek to understand how the host inflammatory response facilitates bacterial outgrowth in the middle ear. Using B cell-deficient infant mice, we show that antibodies play a crucial role in facilitating pneumococcal replication. We subsequently show that this is due to antibody-dependent neutrophil extracellular trap (NET) formation in the middle ear, which, instead of clearing the infection, allows the bacteria to replicate. We further demonstrate the importance of these NETs as a potential therapeutic target through the transtympanic administration of a DNase, which effectively reduces the bacterial load in the middle ear. Taken together, these data provide novel insight into how pneumococci are able to replicate in the middle ear cavity and induce disease.
