This chapter presents the preliminary findings of a qualitative study exploring people’s information experiences during the 2012 Queensland State election in Australia. Six residents of South East Queensland who were eligible to vote in the state election participated in a semi-structured interview. The interviews revealed five themes that depict participants’ information experience during the election: information sources, information flow, personal politics, party politics and sense making. Together these themes represent what is experienced as information, how information is experienced, as well as contextual aspects that were unique to voting in an election. The study outlined here is one in an emerging area of enquiry that has explored information experience as a research object. This study has revealed that people’s information experiences are rich, complex and dynamic, and that information experience as a construct of scholarly inquiry provides deep insights into the ways in which people relate to their information worlds. More studies exploring information experience within different contexts are needed to help develop our theoretical understanding of this important and emerging construct.

How do agents with limited cognitive capacities flourish in informationally impoverished or unexpected circumstances? Aristotle argued that human flourishing emerged from knowing about the world and our place within it. If he is right, then the virtuous processes that produce knowledge, best explain flourishing. Influenced by Aristotle, virtue epistemology defends an analysis of knowledge where beliefs are evaluated for their truth and the intellectual virtue or competences relied on in their creation. However, human flourishing may emerge from how degrees of ignorance are managed in an uncertain world. Perhaps decision-making in the shadow of knowledge best explains human wellbeing—a Bayesian approach? In this dissertation I argue that a hybrid of virtue and Bayesian epistemologies explains human flourishing—what I term homeostatic epistemology. Homeostatic epistemology supposes that an agent has a rational credence p when p is the product of reliable processes aligned with the norms of probability theory; whereas an agent knows that p when a rational credence p is the product of reliable processes such that: 1) p meets some relevant threshold for belief (such that the agent acts as though p were true and indeed p is true), 2) p coheres with a satisficing set of relevant beliefs and, 3) the relevant set of beliefs is coordinated appropriately to meet the integrated aims of the agent. Homeostatic epistemology recognizes that justificatory relationships between beliefs are constantly changing to combat uncertainties and to take advantage of predictable circumstances. Contrary to holism, justification is built up and broken down across limited sets like the anabolic and catabolic processes that maintain homeostasis in the cells, organs and systems of the body. It is the coordination of choristic sets of reliably produced beliefs that create the greatest flourishing given the limitations inherent in the situated agent.

University libraries worldwide are reconceptualising the ways in which they support the research agenda in their respective institutions. This paper is based on a survey completed by member libraries of the Queensland University Libraries Office of Cooperation (QUL OC), the findings of which may be informative for other university libraries. After briefly examining major emerging trends in research support, the paper discusses the results of the survey specifically focussing on support for researchers and the research agenda in their institutions. All responding libraries offer a high level of research support, however, eResearch support, in general, and research data management support, in particular, have the highest variance among the libraries, and signal possible areas for growth. Areas for follow-up, benchmarking and development are suggested.

The MPEG-21 Multimedia Framework provides for controlled distribution of multimedia works through its Intellectual Property Management and Protection ("IPMP") Components and Rights Expression Language ("MPEG REL"). The IPMP Components provide a framework by which the components of an MPEG-21 digital item can be protected from undesired access, while MPEG REL provides a mechanism for describing the conditions under which a component of a digital item may be used and distributed. This chapter describes how the IPMP Components and MPEG REL were used to implement a series of digital rights management applications at the Cooperative Research Centre for Smart Internet Technology in Australia. While the IPMP Components and MPEG REL were initially designed to facilitate the protection of copyright, the applications also show how the technology can be adapted to the protection of private personal information and sensitive corporate information.

This report analyses the copyright law framework needed to ensure open access to outputs of the Australian academic and research sector such as datasets, articles and theses. It is written in the context of an increasing recognition, in Australia and internationally, that access to knowledge is a key driver of social, cultural and economic development and that publicly funded research should be openly accessible. With the objective of enabling access to knowledge, this Report proposes the development of clear protocols for copyright management (designed as practical and effective tools) for implementation in the Australian academic and research sector The Report explains that with the rise of networked digital technologies our knowledge landscape and innovation system is more and more reliant on best practice copyright management strategies. Furthermore in the 21st century these strategies need to accommodate both the demands for open sharing of knowledge and traditional commercialisation models. To this end, this Report examines the way in which practices for managing copyright, interact with the new web based frameworks that have developed for knowledge creation and dissemination. It focuses on specific areas that are central to the promotion of innovation and creativity in Australia, with emphasis on various types of repositories. More specifically, this Report provides an overview of the principles of copyright law, the concept of open access to knowledge, the recently developed open content models of copyright licensing and proposes a framework for enhancing the management of copyright interests in research and academic output (including electronic theses and dissertations (ETD)). The Report describes a forward work program which, upon implementation, will provide the platform for the development of systems and practices designed to effectively promote open access to knowledge within the Australian academic and research sector. The Report calls upon Australian research and funding institutions to consider their commitment to open access and articulate this in clear polices and copyright management frameworks. It proposes a survey of researchers about their understanding of, attitudes towards and experience with publishing agreements and the provision of model agreements that can facilitate open access and commercialisation objectives. The Report details a methodology for cataloguing and better understanding publishers’ attitudes towards open access. This list aims to be interoperable with the existing SHERPA list based in the UK and accessible through a web interface known as the OAK List. Finally the Report looks at copyright management of open access to ETD and makes proposals for better managing this process. In all of these endeavours the OAK Law Project aims to undertake work that will be of relevance to and can be utilised by key stakeholders.

This paper describes how copyright compliance is managed in a large Australian university, with consideration of both the role the university library plays and also how copyright matters external to the library are managed. The paper looks at the changes in distribution technology and copyright legislation over the last decade, and examines the changes in the University’s ability to disseminate teaching materials, as well as the changes in the requirements for managing the use of copyright material.

We consider boundary layer flow of a micropolar fluid driven by a porous stretching sheet. A similarity solution is defined, and numerical solutions using Runge-Kutta and quasilinearisation schemes are obtained. A perturbation analysis is also used to derive analytic solutions to first order in the perturbing parameter. The resulting closed form solutions involve relatively complex expressions, and the analysis is made more tractable by a combination of offline and online work using a computational algebra system (CAS). For this combined numerical and analytic approach, the perturbation analysis yields a number of benefits with regard to the numerical work. The existence of a closed form solution helps to discriminate between acceptable and spurious numerical solutions. Also, the expressions obtained from the perturbation work can provide an accurate description of the solution for ranges of parameters where the numerical approaches considered here prove computationally more difficult.

We revisit the classical Karman rotating disk problem. A series analysis is used to derive estimates of boundary conditions at the surface. Using these estimates, computed thermal and flow fields for large mass transfer through the disk are readily obtained using a shooting method. The relevance of the problem to practical flows is discussed briefly.
