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.

The ‘feminine revolution in mining’ : a critique

This paper presents an analysis of media reports of Australian women in mine management. It argues that a dominant storyline in the texts is one of gender change; in fact, a ‘feminine revolution’ is said to have occurred in the mining industry and corporate Australia more generally. Despite this celebratory and transformative discourse the female mine managers interviewed in the media texts seek to distance themselves from women/female identity/femininity and take up a script of gender neutrality. It is demonstrated, however, that this script is saturated with the assumptions and definitions of managerial masculinity.

Numerical modelling of porous injection in a radical farming scramjet

A numerical investigation of the behaviour of fuel injection through a porous surface in an inlet-fuelled, radial-farming scramjet is presented. The performance of porous fuel injection is compared to discrete port hole injection at an equivalence ratio of φ ≈ 0.4 for both cases. The comparison is performed at a Mach 6.5 flow condition with a total specific enthalpy of 4.3 MJ/kg. The numerical results are compared to experiments performed in the T4 shock tunnel where available. The presented results demonstrate for the first time, that porous fuel injection has the potential to outperform port hole injectors in scramjet engines in terms of fuel-air mixing, ignition delays and achievable combustion efficiencies despite reduced fuel penetration heights.

H2-O2 porous fuel injection in a radical farming scramjet

This paper reports on the experimental testing of oxygen compatible ceramic matrix composite porous injectors in a nominally two-dimensional hydrogen fuelled and oxygen enriched radical farming scramjet in the T4 shock tunnel facility. All experiments were performed at a dynamic pressure of 146 kPa, an equivalent flight Mach number of 9.7, a stagnation pressure and enthalpy of 40MPa and 4.3 MJ/kg respectively and at a fuelling condition that resulted in an average equivalence ratio of 0.472. Oxygen was pre-mixed with the fuel prior to injection to achieve enrichment percentages of approximately 13%, 15% and 17%. These levels ensured that the hydrogen-oxidiser mix injected into the engine always remained too fuel rich to sustain a flame without any additional mixing with the captured air. Addition of pre-mixed oxygen with the fuel was found to significantly alter the performance of the engine; enhancing both combustion and ignition and converting a previously observed limited combustion condition into one with sustained and noticeable combustion induced pressure rise. Increases in the enrichment percentage lead to further increases in combustion levels and acted to reduce ignition lengths within the engine. Suppressed combustion runs, where a nitrogen test gas was used, confirmed that the pressure rise observed in these experiments as attributed to the oxygen enrichment and not associated with the increased mass injected.

Monitoring phase behavior of sub- and supercritical CO2 confined in porous fractal silica with 85% porosity

Phase behavior of CO2 confined in porous fractal silica with volume fraction of SiO2 φs = 0.15 was investigated using small-angle neutron scattering (SANS) and ultrasmall-angle neutron scattering (USANS) techniques. The range of fluid densities (0<(FCO2)bulk<0.977 g/cm3) and temperatures (T=22 °C, 35 and 60 °C) corresponded to gaseous, liquid, near critical and supercritical conditions of the bulk fluid. The results revealed formation of a dense adsorbed phase in small pores with sizes D<40 A° at all temperatures. At low pressure (P <55 bar, (FCO2)bulk <0.2 g/cm3) the average fluid density in pores may exceed the density of bulk fluid by a factor up to 6.5 at T=22 °C. This “enrichment factor” gradually decreases with temperature, however significant fluid densification in small pores still exists at temperature T=60°C, i.e., far above the liquid-gas critical temperature of bulk CO2 (TC=31.1 °C). Larger pores are only partially filled with liquid-like adsorbed layer which coexists with unadsorbed fluid in the pore core. With increasing pressure, all pores become uniformly filled with the fluid, showing no measurable enrichment or depletion of the porous matrix with CO2.

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.

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.
