Manifolds, patterns and transitions in a creative life

Using sculpture and drawing as my primary methods of investigation, this research explores ways of shifting the emphasis of my creative visual arts practice from object to process whilst still maintaining a primacy of material outcomes. My motivation was to locate ways of developing a sustained practice shaped as much by new works, as by a creative flow between works. I imagined a practice where a logic of structure within discrete forms and a logic of the broader practice might be developed as mutually informed processes. Using basic structural components of multiple wooden curves and linear modes of deployment – in both sculptures and drawings – I have identified both emergence theory and the image of rhizomic growth (Deleuze and Guattari, 1987) as theoretically integral to this imagining of a creative practice, both in terms of critiquing and developing works. Whilst I adopt a formalist approach for this exegesis, the emergence and rhizome models allow it to work as a critique of movement, of becoming and changing, rather than merely a formalism of static structure. In these models, therefore, I have identified a formal approach that can be applied not only to objects, but to practice over time. The thorough reading and application of these ontological models (emergence and rhizome) to visual arts practice, in terms of processes, objects and changes, is the primary contribution of this thesis. The works that form the major component of the research develop, reflect and embody these notions of movement and change.

Cultural economic geography and global media studies : the rise of asian media capitals?

This paper considers the scope to develop an approach to the spatial dimensions of media and culture that is informed by cultural-economic geography. I refer to cultural-economic geography as that strand of research in the field of geography that has been informed on the one hand by the ‘cultural turn’ in both geographical and economic thought, and which focuses on the relationship between, space, knowledge and identity in the spheres of production and consumption, and on the other to work by geographers that has sought to map the scale and significance of the cultural or creative industries as new drivers of the global economy. The paper considers the extent to which this work enables those engaged with urban cultural policy to get beyond some of the impasses that have arisen with the development of “creative cities” policies derived from the work of authors such as Richard Florida as well as the business management literature on clusters. It will frame these debates in the context of recent work by Michael Curtin on media capitals, and the question of whether cities in East Asia can emerge as media capitals from outside of the US-Europe-dominated transnational cultural axis.

Strengthening and formally verifying privacy in identity management systems

In a digital world, users’ Personally Identifiable Information (PII) is normally managed with a system called an Identity Management System (IMS). There are many types of IMSs. There are situations when two or more IMSs need to communicate with each other (such as when a service provider needs to obtain some identity information about a user from a trusted identity provider). There could be interoperability issues when communicating parties use different types of IMS. To facilitate interoperability between different IMSs, an Identity Meta System (IMetS) is normally used. An IMetS can, at least theoretically, join various types of IMSs to make them interoperable and give users the illusion that they are interacting with just one IMS. However, due to the complexity of an IMS, attempting to join various types of IMSs is a technically challenging task, let alone assessing how well an IMetS manages to integrate these IMSs. The first contribution of this thesis is the development of a generic IMS model called the Layered Identity Infrastructure Model (LIIM). Using this model, we develop a set of properties that an ideal IMetS should provide. This idealized form is then used as a benchmark to evaluate existing IMetSs. Different types of IMS provide varying levels of privacy protection support. Unfortunately, as observed by Jøsang et al (2007), there is insufficient privacy protection in many of the existing IMSs. In this thesis, we study and extend a type of privacy enhancing technology known as an Anonymous Credential System (ACS). In particular, we extend the ACS which is built on the cryptographic primitives proposed by Camenisch, Lysyanskaya, and Shoup. We call this system the Camenisch, Lysyanskaya, Shoup - Anonymous Credential System (CLS-ACS). The goal of CLS-ACS is to let users be as anonymous as possible. Unfortunately, CLS-ACS has problems, including (1) the concentration of power to a single entity - known as the Anonymity Revocation Manager (ARM) - who, if malicious, can trivially reveal a user’s PII (resulting in an illegal revocation of the user’s anonymity), and (2) poor performance due to the resource-intensive cryptographic operations required. The second and third contributions of this thesis are the proposal of two protocols that reduce the trust dependencies on the ARM during users’ anonymity revocation. Both protocols distribute trust from the ARM to a set of n referees (n > 1), resulting in a significant reduction of the probability of an anonymity revocation being performed illegally. The first protocol, called the User Centric Anonymity Revocation Protocol (UCARP), allows a user’s anonymity to be revoked in a user-centric manner (that is, the user is aware that his/her anonymity is about to be revoked). The second protocol, called the Anonymity Revocation Protocol with Re-encryption (ARPR), allows a user’s anonymity to be revoked by a service provider in an accountable manner (that is, there is a clear mechanism to determine which entity who can eventually learn - and possibly misuse - the identity of the user). The fourth contribution of this thesis is the proposal of a protocol called the Private Information Escrow bound to Multiple Conditions Protocol (PIEMCP). This protocol is designed to address the performance issue of CLS-ACS by applying the CLS-ACS in a federated single sign-on (FSSO) environment. Our analysis shows that PIEMCP can both reduce the amount of expensive modular exponentiation operations required and lower the risk of illegal revocation of users’ anonymity. Finally, the protocols proposed in this thesis are complex and need to be formally evaluated to ensure that their required security properties are satisfied. In this thesis, we use Coloured Petri nets (CPNs) and its corresponding state space analysis techniques. All of the protocols proposed in this thesis have been formally modeled and verified using these formal techniques. Therefore, the fifth contribution of this thesis is a demonstration of the applicability of CPN and its corresponding analysis techniques in modeling and verifying privacy enhancing protocols. To our knowledge, this is the first time that CPN has been comprehensively applied to model and verify privacy enhancing protocols. From our experience, we also propose several CPN modeling approaches, including complex cryptographic primitives (such as zero-knowledge proof protocol) modeling, attack parameterization, and others. The proposed approaches can be applied to other security protocols, not just privacy enhancing protocols.

Aesthetic tensions : evaluating outcomes for practice-led research and industry

This paper explores principles of contemporary aesthetics to suggest a basis for determining qualitative outcomes of artistic works in two contexts: the arts industry and the academy setting of practice-led research. Commonly articulated measures of quality—creativity and innovation—are questioned as mere rhetoric if not framed in specific ways in the two discrete settings. The paper also interrogates generally held assumptions that a longer time to develop work and greater periods of self-reflexivity will produce higher calibre artistic outcomes. The unease produced by apparent differences in qualitative outcomes between art works created in an industry setting and those created through practice-led research is analysed through three interconnected framing devices: intention, contextual parameters and criteria for evaluation, in conjunction with the relationships between the art work, the artist and the audience/viewer/listener. Common and differentiated criteria in the two contexts are explored, leading to the conclusion that innovation is more likely to be revealed in the end product in an industry context whereas in practice-led research it may be in the methodological processes of creating the work. While identifying and acknowledging that the two contexts encourage and produce distinctive qualitative artistic outcomes, both of value to the arts and the academy, the paper recommends ways in which closer formal liaison between industry artists and practice-led artists and supervisors might occur in order to ensure ongoing mutual influence and relevance.

What will the Apple iPad deliver for newspapers?

The launch of the Apple iPad in January 2010 was one of the most anticipated and publicised launched of a new technological device in recent history. Positioning itself as between a smart phone and a PC, but with the attributes of both, Apple have sought to develop a new market niche with the iPad for tablet PC devices, and early signs are that market expectations are being met.. The iPad’s launch was potentially fortuitous for the newspaper industry worldwide, as it offered the potential to address its two recurring problems: the slow but inexorable decline of print media circulation, and the inability to satisfactorily monetise online readerships. As a result, the Apple iPad has benefited from an enormous amount of free publicity in newspapers, as they develop their own applications (apps) for the device. This paper reports on findings from work undertaken through Smart Services CRC into potential take-up and likely uses of the iPad, and their implications for the news media industry. It reports on focus group analysis undertaken in the mid-2010 using “customer job mapping” methodologies, that draw attention to current gaps in user behaviour in terms of available devices, in order to anticipate possibilities beyond the current “three screens” of PC, mobile phone and television.

Journalism as social networking : the Australian youdecide project and the 2007 federal election

The increasing prevalence of new media technologies and the rise of citizen journalism has coincided with a crisis in industrial journalism –as the figure of the "journalist as hero" is fading, new media forms have facilitated the production of news content "from below" by citizens and "pro-am" journalists. Participation in an action-research project run during the 2007 Australian Federal Election, youdecide 2007, allowed the authors to gain first-hand insights into the progress of citizen-led news media in Australia, but also allowed us to develop an account of what the work of facilitating citizen journalism involves. These insights are important to understanding the future of professional journalism and journalism education, as more mainstream media organizations move to accommodate and harness user-created content. The paper considers the relevance of citizen journalism projects as forms of R&D for understanding news production and distribution in participatory media cultures, and the importance of grounded case studies for moving beyond normative debates about new media and the future of journalism.

Evaluation of accessibility for knowledge-based cities

Purpose: The purpose of the paper is to develop a framework for evaluation of accessibility for knowledge based cities. ----- ----- Design/methodology/approach: This approach notifies common mistakes and problems in accessibility assessment for knowledge cities. ----- ----- Originality/value: Accessibility plays a key role in transport sustainability and recognizes the crucial links between transport and sustainable goals like air quality, environmental resource consumption & social equity. In knowledge cities, accessibility has significant effects on quality of life and social equity by improving the mobility of people and goods. Accessibility also influences patterns of growth and economic health by providing access to land. Accessibility is not only one of the components of knowledge cities but also affects other elements of knowledge cities directly or indirectly. ----- ----- Practical implications: The outcomes of the application will be helpful for developing particular methodologies for evaluating knowledge cities. On other words, this methodology attempts to develop an assessment procedure for examining accessibility of knowledge-based cities.

Assessing and learning in internships: Reflecting on pedagogy and progress

An elective internship unit as part of a work integrated learning program in a business faculty is presented as a case study. In the unit, students complete a minimum of 120 hours work placement over the course of a 13 week semester. The students are majoring in advertising, marketing, or public relations and are placed in corporations, government agencies, and not for profit organisations. To support and scaffold the students’ learning in the work environment, a range of classroom and online learning activities are part of the unit. Classroom activities include an introductory workshop to prepare students for placement, an industry panel, and interview workshop. These are delivered as three workshops across the semester. Prior to commencing their placement, students complete a suite of online learning modules. The Work Placement Preparation Program assists students in securing obtaining a placement and make a successful transition to the work environment. It provides an opportunity for students to source possible work placement sites, prepare competitive applications, develop and rehearse interview skills, deal with workplace issues, and use a student ePortfolio to reflect on their skills and achievements. Students contribute to a reflective blog throughout their placement, with feedback from academic supervisors throughout the placement. The completion of the online learning modules and contribution to a reflective blog are assessed as part of the unit. Other assessment tools include a internship plan and learning contract between the student, industry supervisor, and academic supervisor; job application including responses to selection criteria; and presentation to peers, academics and industry representatives at a poster session. The paper discusses the development of the internship unit over three years, particularly learning activities and assessment. The reflection and refinement of the unit is informed by a pedagogical framework, and the development of processes to best manage placement for all stakeholders. A model of best practice is proposed, that can be adapted to a variety of discipline areas.

Developing reflective practitioners online: The business of blogs in work integrated learning

Reflective practice is widely considered across discussions around educational psychology, professional identity, employability of graduates, and generic or graduate capabilities. Critical reflection is essential for providing a bridge between the university and the workplace, and for ultimately preparing work ready graduates (Patrick et al, 2008). Work integrated learning, particularly through internships and work placements for students, is viewed as a valuable approach for students developing skills in reflective practice. Reflective journals are one of the tools often used to encourage and develop student reflection. Shifting the reflective journal to an online interface as a reflective blog presents opportunities for more meaningful, frequent and richer interaction between the key players in a work integrated learning experience. This paper examines the adoption, implementation and refinement of the use of reflective blogs in a work integrated learning unit for business students majoring in advertising, marketing and public relations disciplines. The reflective blog is discussed as a learning and assessment tool, including the approaches taken to integrate and scaffold the blog as part of the work integrated learning experience. Graduate capabilities were used as cornerstones for students to frame students’ thinking, experiences and reflection. These capabilities emphasise the value of coherent theoretical and practical knowledge, coupled with critical, creative and analytical thinking, problem solving skills, self reliance and resilience. Underlying these graduate capabilities is a focus on assessment for learning matched with assessment of learning. Using specific triggers and prompts as part of the reflective process, and incorporating ongoing feedback from academic supervisors, students moved from descriptive levels of reflection, to more meaningful and critical reflection. Students’ blogs are analysed to identify key themes, challenges and achievements in the work integrated learning experience. Suggestions for further development and improvement, together with a model of best practice, are proposed.

Support for gold open access publishing strategies at QUT

INTRODUCTION: Since the introduction of its QUT ePrints institutional repository of published research outputs, together with the world’s first mandate for author contributions to an institutional repository, Queensland University of Technology (QUT) has been a leader in support of green road open access. With QUT ePrints providing our mechanism for supporting the green road to open access, QUT has since then also continued to expand its secondary open access strategy supporting gold road open access, which is also designed to assist QUT researchers to maximise the accessibility and so impact of their research. ---------- METHODS: QUT Library has adopted the position of selectively supporting true gold road open access publishing by using the Library Resource Allocation budget to pay the author publication fees for QUT authors wishing to publish in the open access journals of a range of publishers including BioMed Central, Public Library of Science and Hindawi. QUT Library has been careful to support only true open access publishers and not those open access publishers with hybrid models which “double dip” by charging authors publication fees and libraries subscription fees for the same journal content. QUT Library has maintained a watch on the growing number of open access journals available from gold road open access publishers and their increased rate of success as measured by publication impact. ---------- RESULTS: This paper reports on the successes and challenges of QUT’s efforts to support true gold road open access publishers and promote these publishing strategy options to researchers at QUT. The number and spread of QUT papers submitted and published in the journals of each publisher is provided. Citation counts for papers and authors are also presented and analysed, with the intention of identifying the benefits to accessibility and research impact for early career and established researchers.---------- CONCLUSIONS: QUT Library is eager to continue and further develop support for this publishing strategy, and makes a number of recommendations to other research institutions, on how they can best achieve success with this strategy.

Preparing library staff for research support services at QUT

INTRODUCTION: Queensland University of Technology (QUT) Library is partnering with High Performance Computing (HPC) services and the Division of Research and Commercialisation to develop and deliver a range of integrated research support services and systems designed to enhance the research capabilities of the University. Existing and developing research support services include - support for publishing strategies including open access, bibliographic citation and ranking services, research data management, use of online collaboration tools, online survey tools, quantitative and qualitative data analysis, content management and storage solutions. In order to deliver timely and effective research referral and support services, it is imperative that library staff maintain their awareness of, and develop expertise in new eResearch methods and technologies. ---------- METHODS: In 2009/10 QUT Library initiated an online survey for support staff and researchers and a series of focus groups for researchers aimed at gaining a better understanding of current and future eresearch practices and skills. These would better inform the development of a research skills training program and the development of new research support services. The Library and HPC also implemented a program of seminars and workshops designed to introduce key library staff to a broad range of eresearch concepts and technologies. Feedback was obtained after each training session. A number of new services were implemented throughout 2009 and 2010. ---------- RESULTS: Key findings of the survey and focus groups are related to the development of the staff development program. Feedback from program attendees is provided and evaluated. The staff development program is assessed in terms of its success to support the implementation of new research support services. --------- CONCLUSIONS QUT Library has embarked on an ambitious awareness and skills development program to assist Library staff transition a period of rapid change and broadening scope for the Library. Successes and challenges of the program are discussed. A number of recommendations are made in retrospect and also looking forward to the future training needs of Library staff to support the University’s future research goals.

Rethinking public service media and citizenship : digital strategies for news and current affairs at Australia’s Special Broadcasting Service (SBS)

This article considers the concept of media citizenship in relation to the digital strategies of the Special Broadcasting Service (SBS). At SBS, Australia’s multicultural public broadcaster, there is a critical appraisal of its strategies to harness user-created content (UCC) and social media to promote greater audience participation through its news and current affairs Web sites. The article looks at the opportunities and challenges that user-related content presents for public service media organizations as they consolidate multiplatform service delivery. Also analyzed are the implications of radio and television broadcasters’ moves to develop online services. It is proposed that case study methodologies enable an understanding of media citizenship to be developed that maintains a focus on the interaction between delivery technologies, organizational structures and cultures, and program content that is essential for understanding the changing focus of 21st-century public service media.

The determinants of multinational contractors' willingness to bid for Australian public sector major infrastructure projects : towards deploying the eclectic paradigm of internationalisation

Against a background of already thin markets in some sectors of major public sector infrastructure in Australia and the desire of Australian federal government to leverage private finance, concerns about ensuring sufficient levels of competition are prompting federal government to seek new sources of in-bound Foreign Direct Income. The aim of this paper is to justify and develop a means to deploying the eclectic paradigm of internationalisation that forms part of an Australian federally funded research project designed to explain the determinants of multinational contractors' willingness to bid for Australian public sector major infrastructure projects. Despite the dominance of the eclectic paradigm as a theory of internationalisation for over two decades, it has seen limited application in terms of multinational construction. It is expected that the research project will be the first empirical study to deploy the eclectic paradigm to inbound FDI to Australia whilst using the dominant economic theories advocated for use within the eclectic paradigm. Furthermore, the research project is anticipated to yield a number of practical benefits. These include estimates of the potential scope to attract more multinational contractors to bid for Australian public sector infrastructure, including the nature and extent to which this scope can be influenced by Australian governments responsible for the delivery of infrastructure. On the other hand, the research is also expected to indicate the extent to which indigenous and other multinational contractors domiciled in Australia are investing in special purpose technology and achieving productivity gains relative to foreign multinational contractors.

Engaging marketing students : student operated businesses in a simulated world

Engaged students are committed and more likely to continue their university studies. Subsequently, they are less resource intensive from a university’s perspective. This article details an experiential second-year marketing course that requires students to develop real products and services to sell on two organized market days. In the course, students participate as both consumers and marketers in a simulated world. The current article explores the effectiveness of this experiential assessment in terms of its ability to engage students. Comparing student engagement to a traditional lecture course and National Survey of Student Engagement benchmarks, the results suggest that the use of a simulated marketplace is capable of engaging students. Specifically, the assessment reported encourages more active learning and collaboration, is more academically challenging, and permits more student–faculty interaction than a traditional lecture-based course. The course structure outlined in this article permits the dynamics of a live marketing environment to be introduced into the classroom. The authors provide practical advice for educators seeking to design and implement engaging pedagogy.

Augmenting public urban spaces : the impact of the digital future on the design of public urban spaces

Social media digital and technologies surround us. We are moving into an age of ubiquitous (that is everywhere) computing. New media and information and communication technologies already impact on many aspects of everyday life including work, home and leisure. These new technologies are influencing the way that we develop social networks; understand places and location; how we navigate our cities; how we provide information about utilities and services; developing new ways to engage and participate in our communities, in planning, in governance and other decisions. This paper presents the initial findings of the impacts that digital communication technologies are having on public urban spaces. It develops a contextual review the nexus between urban planning and technological developments with examples and case studies from around the world to highlight some of the potential directions for urban planning in Queensland and Australia. It concludes with some thought provoking discussion points for urban planners, architects, designers and placemakers on the future of urban informatics and urban design, questions such as: how technology can enhance ‘place’, how technology can be used to improve public participation, and how technology will change our requirements of public places?
