Empowering protest through social media

Advances in personal communications devices including smartphones, are enabling individuals to establish and form virtual communities in cyberspace. Such platforms now allow users to be in continuous contact, enabling them to receive information in real time, which allows them to act in support of other members of their network. This paper will discuss some of the capabilities afforded by social media to protest groups focused on civil disobedience. Direct action protests are now a common sight at gatherings of world leaders, most notably the meeting of the World Trade Organisation (WTO) in Seattle in 1999, the G20 meetings in Melbourne in 2006 and Toronto in 2010. Facebook and Twitter are becoming recognised as key mediums from which to drive change, exert influence and strategically and tactically outmaneuver conventional police deployments at protests. Police charged with managing protest activity now need to operate in both the physical and cyber worlds simultaneously

Material murmurings

This thesis, Material Murmurings, comprising of exegesis and creative practice, focuses on the central research question: “How do we understand the materiality of glass and what happens when said materiality is approached through feminist scholarship?” This question forms the basis for an investigation through creative practice and analysis via an interpretive framework of feminist knowledges of the body. The creative practice embraces glass as the central medium with a series of exhibitions that responded to the interpretive paradigm. It is expected that Material Murmurings will highlight and make evident the value of post-technical approaches in glass art which have only recently become an acknowledged form of contemporary visual arts within Australia and, to a lesser degree, the broader international context. The intention of this thesis is to address the lack of dialogue surrounding glass as a contemporary visual arts material by discussing how female artists have been using glass within their practice through a paradigm of feminist scholarship of the body. A lack of formalised inquiry into the material depth of glass exists. Through formalising this discussion via a framework of feminist knowledges, the study will open up the possibilities for writing about glass, allowing for the expansion of the dialogue surrounding contemporary glass art. The study will also make visible and highlight the breadth and diversity of contemporary glass works being produced particularly by female visual artists, embracing the material itself for its depth and wealth of possible meaning. The exegesis pays particular attention to the work of female artists who have embraced glass for its materiality. Materiality is understood as the insistence of meaning that a material contributes to a work of art; the qualities, history and function beyond the decorative or aesthetic value that the material contributes to the artwork. My feminist visual arts praxis has provided the motivation for this exegesis and my obsession with glass has driven the choices of artists and theorists discussed. The exegesis demonstrates how glass can be interpreted/read/understood within the visual arts through a feminist lens. Various exhibitions through the research period culminated in a final exhibition titled Material Murmurings (2013). These exhibitions revealed different ways of critically interpreting and locating glass works beyond the traditional craft paradigm. This research has responded to the contemporary scholarly call for a need for visual arts critical review to be more inclusive of contemporary glass works, and has provided through practice-led research that is inclusive of materiality, praxis and process, a basis for this, with significant outcomes exhibited as artefact/object/publication

Data-driven agriculture for rural smallholdings

Spatial information science has a critical role to play in meeting the major challenges facing society in the coming decades, including feeding a population of 10 billion by 2050, addressing environmental degradation, and acting on climate change. Agriculture and agri-food value-chains, dependent on spatial information, are also central. Due to agriculture\u27s dual role as not only a producer of food, fibre and fuel, but also as a major land, water and energy consumer, agriculture is at the centre of both the food-water-energy-environment nexus and resource security debates. The recent confluence of a number of advances in data analytics, cloud computing, remote sensing, computer vision, robotic and drone platforms, and IoT sensors and networks have lead to a significant reduction in the cost of acquiring and processing data for decision support in the agricultural sector. When combined with cost-effective automation through development of swarm farming technologies, the technology has the potential to decouple productivity and cost efficiency from economies of size, reducing the need to increase farm size to remain economically viable. We argue that these pressures and opportunities are driving agricultural value-chains towards high-resolution data-driven decision-making, where even decisions made by small rural landowners can be data-driven. We survey recent innovations in data, especially focusing on sensor, spatial and data mining technologies with a view to their agricultural application; discuss economic feasibility for small farmers; and identify some technical challenges that need to be solved to reap the benefits. Flexibly composable information resources, coupled with sophisticated data sharing technologies, and machine learning with transparently embedded spatial and aspatial methods are all required

Football\u27s world cup and its fans - reflections on national styles : a photo essay on Germany 2006

The football World Cup is the greatest multicultural sporting extravaganza of modern times. The notion of post-fandom tries to capture the ways in which fans now participate in and engage in self-aware and reflexive strategies to obtain their desired outcomes from attendance at or viewing such major events. This illustrated photo-essay on the World Cup looks at the experiences and behaviour of fans in three countries, Scotland, Germany and Australia, during the tournament with a view to extending our understanding of the relationships between fans and others temporarily interested in the World Cup and the promoters of such mega-events. It argues that the participants brought a wide range of expectations to the tournament and engaged in highly flexible and innovative approaches to ensure that they gained the maximum benefit, individually and collectively, from the experience. <br /

Data centre optimisation enhanced by software defined networking

Contemporary Cloud Computing infrastructures are being challenged by an increasing demand for evolved cloud services characterised by heterogeneous performance requirements including real-time, data-intensive and highly dynamic workloads. The classical way to deal with dynamicity is to scale computing and network resources horizontally. However, these techniques must be coupled effectively with advanced routing and switching in a multi-path environment, mixed with a high degree of flexibility to support dynamic adaptation and live-migration of virtual machines (VMs). We propose a management strategy to jointly optimise computing and networking resources in cloud infrastructures, where Software Defined Networking (SDN) plays a key enabling role

Contemporary Kitsch: An examination through creative practice

This exegesis examines the theoretical concept of contemporary kitsch within a creative practice that incorporates sculptural and installation art. Kitsch is a distinct aesthetic style. Once designated to the rubbish bin of culture, kitsch was considered to be low class, bad taste cheap fakes and copies (Greenberg, 1961; Adorno & Horkheimer, 1991; Calinescu, 1987; Dorfles, 1969). I argue, however, that this is no longer the case. This research critically examines the way in which contemporary kitsch now plays a vital and positive role in social and individual aesthetic life. Although there are conflicting points of view and distinct variations between recent cultural commentators (Olalquiaga, 1992; Binkley, 2000; Attfield, 2006) on what kitsch is, there is a common sentiment that “the repetitive qualities of kitsch address . . . a general problem of modernity” (Binkley, p. 131). The research aligns the repetitive qualities to what sociologist Anthony Giddens (1991) refers to as “dissembeddedness” (1991) or “the undermining of personal horizons of social and cosmic security” (Binkley, 1991, p.131). The research investigates: how the sensory affect of sentimentality imbued in the kitsch experiences, possessions and material objects people covet and collect, offer a way of the individual moving from disembeddedness to a state of being re-embedded; and locates the ways in which the artist can facilitate the re-embedding experience. Through this lens it is demonstrated that kitsch has become firmly rooted in our “lifeworlds” (Habermas, 1971), as an aesthetic that reveals “how people make sense of the world through artefacts” (Attfield, 2006, p. 201) and everyday objects; that the sensory affect of sentimentality on connections to possessions and material objects that contemporary kitsch offers is shared across cultures and societie

A survey on the cyber security of Small-to-Medium businesses: Challenges, research focus and recommendations

Small-to-medium sized businesses (SMBs) constitute a large fraction of many countries’ economies but according to the literature SMBs are not adequately implementing cyber security which leaves them susceptible to cyber-attacks. Furthermore, research in cyber security is rarely focused on SMBs, despite them representing a large proportion of businesses. In this paper we review recent research on the cyber security of SMBs, with a focus on the alignment of this research to the popular NIST Cyber Security Framework (CSF). From the literature we also summarise the key challenges SMBs face in implementing good cyber security and conclude with key recommendations on how to implement good cyber security. We find that research in SMB cyber security is mainly qualitative analysis and narrowly focused on the Identify and Protect functions of the NIST CSF with very little work on the other existing functions. SMBs should have the ability to detect, respond and recover from cyber-attacks, and if research lacks in those areas, then SMBs may have little guidance on how to act. Future research in SMB cyber security should be more balanced and researchers should adopt well-established powerful quantitative research approaches to refine and test research whilst governments and academia are urged to invest in incentivising researchers to expand their research focus

CloudNetSim - Simulation of Real-Time Cloud Computing Applications

In this paper, we describe CloudNetSim, a project aiming to realise a simulation platform supporting our ongoing and planned research activities in the area of resource management and scheduling for distributed QoS-sensitive and soft real-time applications. It is based on OMNeT++, integrating in the platform a set of modules for the simulation of CPU scheduling, including hierarchical scheduling at both levels of the hypervisor and guest Operating System, as needed when simulating cloud infrastructures. Thanks to the modularity of OMNeT++, CloudNetSim may easily leverage many existing simulation models already available for networking, including standard network components and protocols, such as TCP/IP. After a brief overview of related simulation tools found in the literature, and the discussion of their limitations, we provide a detailed description of the internals of our simulator. Then, we show results gathered from a few representative scenarios demonstrating how its behaviour matches with the one of simple real applications

Brokering SLAs for end-to-end QoS in cloud computing

In this paper, we present a brokering logic for providing precise end-to-end QoS levels to cloud applications distributed across a number of different business actors, such as network service providers (NSP) and cloud providers (CSP). The broker composes a number of available offerings from each provider, in a way that respects the QoS application constraints while minimizing costs incurred by cloud consumers.
